There are many components of the waste paper hydraulic baler. Among them, the hydraulic pump, hydraulic motor and engine of the waste paper hydraulic baler are the two core components in the hydraulic system. Their reasonable selection can improve the efficiency of the system and ensure the horizontal waste paper baling. It is very important for the machine to work reliably, reduce energy consumption, and reduce noise. The compression frame of the mineral water bottle packing machine is basically similar in structure to the compression frame, but there are 4 packing heads and 1 set of thread feeding device arranged on it. The packing heads of the waste paper hydraulic baler (4 in total) are the most complex parts of the whole equipment and the most interlocked parts. The packing heads of each waste paper hydraulic baler have exactly the same structure and can be interchanged. The lead frame of the automatic waste paper baler is composed of 4 sets of wire devices installed on a frame. The entire lead frame is suspended on a central axis of the compression frame, and moves horizontally relative to the compression frame under the action of a hydraulic motor. The compression frame is a welded component, and the bottom is equipped with wheels, which can move horizontally along the main slide rail under the push of a hydraulic cylinder. The lifting platform is mainly formed by bolting two horizontal beams, and the lifting platform can move up and down in the vertical direction under the push of two hydraulic cylinders. The automatic waste paper baler is a mechatronic product, mainly composed of mechanical systems, control systems, feeding systems and power systems. The whole packing process is composed of auxiliary time such as pressing, returning, carrying, transferring, outgoing up, outgoing down, and receiving. The hydraulic pump is a power component that provides a certain flow rate (unit: cubic meters per second) and pressure to the hydraulic system of the waste paper hydraulic baler. The waste paper baler is an indispensable core component of every hydraulic system. It is reasonable The selection of hydraulic pump is very important for reducing the energy consumption of the hydraulic system of the waste paper hydraulic baler, improving the efficiency of the system, reducing noise, improving the performance and ensuring the reliability of the system. The principle of selecting the hydraulic pump is: according to the working condition of the main machine of the waste paper hydraulic baler, the power (referring to the amount of work done by the object in a unit time) and the performance requirements of the system, first determine the type of hydraulic pump, and then Determine its specifications and models according to the pressure and flow required by the system. Generally, gear pumps and double-acting vane pumps can be selected for light-load and low-power hydraulic equipment; for mechanical equipment with higher precision (small waste paper baler), double-acting vane pumps and incandescent rod pumps can be used; For mechanical equipment with fast and slow feed (horizontal waste paper baler), the waste paper baler in Chongli County can choose pressure-limiting variable vane pump and double vane pump; equipment with large load and high power ( Waste paper baler), plunger pump can be used; auxiliary equipment of mechanical equipment, such as feeding, clamping and other unimportant occasions, can choose low-cost gear pump. Customers can purchase auxiliary materials for these waste paper hydraulic balers at low prices. Save long-term costs.
