Application principle of hydraulic servo system 2020-02-16

Servo hydraulic drive system is an automatic control system that takes mechanical position or angle as the control object, for example, hydraulic baler machine, CNC machine tool, etc.

  The driving motor used in the servo system requires fast response speed, accurate positioning and moment of inertia (the moment of inertia of the servo motor used in the electromechanical system is large, in order to be directly connected to mechanical parts such as the screw. There is a special type of servo motor Small inertia motor, in order to obtain extremely high response speed. However, this type of motor has low overload capacity, when used in the feed servo system, it must be accelerated and decelerated. The moment of inertia reflects the acceleration characteristics of the system. The moment of inertia of the system cannot be greater than 3 times of the moment of inertia of the motor.) This type of special motor is called a servo motor.

  Of course, its basic working principle is no different from ordinary AC and DC motors. The dedicated drive unit for this type of motor is called a servo drive unit, sometimes referred to as a servo, and generally contains a closed loop of current, speed, and / or position.

  Servo is a term for performance. Generally, as long as the approximation of the command and control results reaches a certain level, it can be called servo, which has no direct relationship with the structure of the machine. For example, the servo system does not have a precise range of inertia matching. This is because the result of inertia matching is only as long as it does not affect the control object to follow or influence the main command, and it does not matter whether it is 3 or 3.5. The servo system is not necessarily a motor system, and some pneumatic systems are called pneumatic servos.

The servo system is essentially a servo system. It's just that the quantity being controlled is displacement or its derivative with time.

  If you want to ask what a servo system is, the output of a system reproduces the input signal in the fastest and most accurate way possible. Its measurement indicators are overshoot and delay.

The servo system is an automatic control system that enables the output controlled quantity of the object such as the position, orientation and state to follow the arbitrary change of the input target (or given value).

The main task of the servo is to amplify, transform and adjust the power according to the requirements of the control command, so that the torque, speed and position control output by the drive device are very flexible and convenient.as more information ,please visit : www.nickbaler.net

Waste paper baler supply and demand receives the impact of logistics after the Spring Festival 2020-02-13

Affected by the prolongation of the Spring Festival holiday, the operating rate of paper enterprises is not high, and downstream enterprises are still in a state of rest.
In terms of logistics: transportation is blocked, and the new order volume is not large. At present, most local production enterprises resume work in accordance with the postponement plan, but the possibility of postponing the resumption of production in some regional production companies will not be ruled out.
In terms of raw materials: most baling stations have slow resumption of work, and domestic baling stations have a low rate of resumption, and paper mills' procurement enthusiasm and arrival volume are relatively low. Affected by the simultaneous delay in supply and demand in the waste paper market, the current price of waste paper is temporarily stable. The amount of approval for waste is reduced, and it is also in the off-season of seasonal trading. Most domestic paper mills choose to wait and see.
On the supply side: Delaying the start of the paper mill has reduced the supply of finished paper to a certain extent, but some traders and downstream customers have been actively preparing for the warehouse before the holiday. In addition, during the Spring Festival, the production lines of large-scale enterprises normally schedule or rotate production, and corrugated box board. The overall supply of the paper market is still relatively sufficient, and the base paper inventory of enterprises that regularly schedule production and rotate production has increased slightly.
On the demand side: the holiday market is mainly closed, and downstream demand recovery is relatively slow after the holiday. Coupled with poor logistics and transportation, paper mills mainly focus on small-scale supply in the surrounding area, and mainly to protect the packaging needs of medical supplies. The overall market demand recovery will take time.
It is expected that in the short term, the corrugated and containerboard market will continue to run lightly and steadily. As downstream demand gradually recovers, the end of February or early March may usher in a small-scale outbreak, but the duration is expected to be short. Therefore, the price of corrugated and containerboard is expected to increase slightly.as more information ,please visit :www.nkbaler.com

Features of straw baler 2020-02-03

The straw baler has the following characteristics:
1. The packing speed is fast. It only takes 1 minute to complete each strap.
2. The use of imported relays for circuit control effectively extends the service life of the equipment;
3. A 2 mm thick rigid plate is used, and the fixed box with warp and weft threads is never welded.
4. The hydraulic baler has a moderate operation height, simple and convenient operation, and more convenient operation, which is suitable for packing lighter items.
5. After improved design and meticulous manufacturing by professional R & D center, the scope of use of hydraulic balers has been continuously expanded, and straw, plastic, pulp, powder, and paper scraps can be packed.
7. The hydraulic baler is a mechanical structure, and some key components use domestic famous brand parts.
Horizontal hydraulic straw baler
The semi-automatic horizontal straw baler equipment is composed of two parts: the host and the conveyor. The main parts are oil pump, PLC, push plate, oil cylinder, etc. The main work purpose is to provide sufficient pressure to compress the straw; the conveyor is controlled by the motor, mainly to coordinate the host to transport the straw. The two cooperate with each other to complete the baling task of straw.
The pressure of the mainframe of the hydraulic straw baler is adjustable, but according to the characteristics of the straw itself, there will be a relatively suitable pressure. Pressure of 140 tons or 160 tons. Of course, if there are special needs, the pressure can be set. Two oil pumps support the work of its pressure and moving speed of the push plate. An oil pump can be used for both pressure and speed, but the moving speed of the push plate is slower. In order to increase the moving speed and increase production efficiency, it is necessary to use another motor to support the pushing and moving of the push disk.
The main purpose of the conveyor is to provide the host with compressible raw materials in a timely manner, because manual feeding is almost impossible. The working efficiency of the main machine is high. If the supply of raw materials is insufficient, the efficiency of the whole machine will be reduced. The conveyor of the straw baler works in unison with the host without affecting each other. When the host silo is full, the conveyor will automatically stop feeding and wait for the host to compress and pack. When the host finishes the compression and packing process, the conveyor will automatically supply straw. The uninterrupted work using the time gap between the two improves the overall efficiency of the equipment.

Straw balers are widely used in various types of straw baler waste paper mills, old waste recycling companies and other unit enterprises. They are used to pack and recycle used waste paper and plastic straws, which improves labor efficiency, reduces labor intensity, saves manpower, and reduces transportation Good equipment.
However, due to the wear and tear of the parts and poor lubrication in the straw baler, the parts may be damaged, and the occurrence of faults and accidents may be enlarged. Therefore, it is very important to quickly find and troubleshoot the fault. Don't call on the manufacturing plant for a glitch, and earn valuable time and money.
Straw balers are used to squeeze waste paper and similar products into knots under normal conditions, and use special packaging tapes to form and reduce the volume, so as to reduce the volume of transportation, save freight, and increase benefits for enterprises.
In order to solve the problem of straw collection, a village began to use straw balers on a trial basis. Each machine can bale 40 acres per day. Farmers will be charged 20 yuan per mu. The baled grass will be sold to the grass station for 160 yuan / ton. From an economic point of view, straw balers have greatly improved work efficiency, reduced the collection and storage process, and reduced costs, thereby promoting the formation of a market-based collection and storage mechanism. From the perspective of environmental protection, the use of straw balers reduces weeds piled up in the field, protects river water conservancy, and further consolidates the results of village environmental improvement.
