Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic balers, specifically relating to a frame-type pusher head for a lift-door horizontal baler. Background Technology

[0002] The pusher head structure of a horizontal baler is one of the core components of the equipment. It is mainly responsible for pushing materials (such as waste paper, plastic, metal, etc.) into the compression chamber for compression and shaping. Its structural design directly affects the baling efficiency, stability, and durability. The pusher head of a horizontal baler needs to compress materials periodically. Over time, the guide of the pusher head is prone to wear, which directly affects the compression stability of the pusher head, resulting in uneven force on the material, insufficient compression, or poor compression shape.

[0003] To address this issue, we designed a frame-type pusher for a lift-door horizontal packing machine, providing an alternative technical solution to the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a frame-type push head for a lift-door horizontal baler, so as to solve the problems mentioned in the background art regarding the use of existing hydraulic balers.

The front end of the frame is connected to the pusher, and the rear end of the frame is welded to the upper baffle. The main pressure cylinder is disposed inside the baffle and the frame, and the front end of the main pressure cylinder is connected to the pusher via a connector. A guide bar is provided on the upper side of the main pressure cylinder, and a guide wheel that mates with the guide bar is provided at the rear end of the upper baffle. Nylon guide plates are provided on both the left and right sides of the upper baffle and the frame.

[0006] Preferably, the bottom of the frame is provided with a wear-resistant guide block, and a guide groove adapted to the wear-resistant guide block is formed on the bottom end face of the frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-3 A frame-type pusher head 6 for a lift-door horizontal baler includes an upper baffle 4, a frame 5, a pusher head 6, and a main pressure cylinder 3. The front end of the frame 5 is connected to the pusher head 6, and the rear end of the frame 5 is welded to the upper baffle 4. The main pressure cylinder 3 is located inside the baffle and the frame 5, and the front end of the main pressure cylinder 3 is connected to the pusher head 6 through a connector 10. A guide bar is provided on the upper side of the main pressure cylinder 3. A guide wheel 1 that docks with the guide bar is provided at the rear end of the upper baffle 4. Nylon guide plates 14 are provided on both the left and right sides of the upper baffle 4 and the frame 5.

[0018] The horizontal baler structure of this design uses the frame 5 as the core load-bearing frame. The front end is rigidly connected to the pusher head 6 via a connector 10 to ensure precise transmission of the pushing action. The rear end of the frame 5 is welded to the upper baffle 4 using continuous welds, forming a stable box-type support structure. The main pressure cylinder 3, as the core power unit, is longitudinally arranged inside the enclosed space formed by the upper baffle 4 and the frame 5. A hardened steel guide bar is parallel to the top of the cylinder barrel of the main pressure cylinder 3, forming a rolling guide mechanism with the guide wheel 1 installed at the end of the upper baffle 4. This mechanism utilizes a V-shaped... The precise fit between the groove and the flange effectively constrains the lateral displacement of the pusher head 6 under high pressure conditions. Nylon guide plates 14 are fixed on the mounting surfaces of the upper baffle 4 and the left and right sides of the frame 5. This not only reduces the friction coefficient during the reciprocating motion of the pusher head 6, but also enables modular maintenance of key friction pairs through the replaceable design of the wear-resistant liner. At the same time, it further limits the movement trajectory of the main pressure cylinder 3, making the compression of the pusher head 6 in this solution more stable and having better guidance, significantly improving the motion accuracy and durability of the equipment under continuous heavy load conditions.

[0019] Furthermore, a wear-resistant guide block 13 is provided at the bottom of the frame 5, and a guide groove adapted to the wear-resistant guide block 13 is provided on the bottom end face of the frame 5.

[0020] In the bottom structure design of the frame 5, two parallel rectangular guide grooves are machined on the bottom plate of the frame 5. NM500 wear-resistant plates with surface hardening treatment are fixed in the grooves to ensure the precise linear movement of the push head 6 assembly under high pressure conditions, and to effectively absorb the vibration energy during equipment operation. The top of the guide block is designed with a continuous V-shaped oil guide groove, which is connected to the automatic lubrication oil injection hole integrated on the side wall of the frame 5 to form a closed-loop lubrication channel, ensuring that a lubricating oil film is continuously formed between the sliding surfaces, which greatly improves the reliability of continuous equipment operation.

[0021] Furthermore, two sets of blades 7 are provided on the upper opening of the pusher head 6, and the blades 7 are detachably connected to the pusher head 6.

[0022] With this technical solution, the pusher head 6 is equipped with a detachable blade 7. When the pusher head 6 moves forward, the blade 7 can cut the long material in the hopper, making the compressed material more regular in shape and easier to bundle later.

[0023] Furthermore, a connector 10 is provided at the front end of the piston rod of the main pressure cylinder 3, and a connector pad 9 is provided at the rear side of the pusher 6. The connector 10 and the connector pad 9 are fixedly connected by a retaining ring 11 and a retaining ring screw 12.

[0024] Furthermore, the front end of the pusher head 6 is provided with multiple sets of wire grooves 8, and the specifications of the wire grooves 8 are set to 70*30mm.

[0025] Working principle: The main structure of this solution includes a pusher head 6, an upper baffle 4, a frame 5, and a main pressure cylinder 3. A guide bar is installed on the main pressure cylinder 3. The rear end of the upper baffle 4 is equipped with a guide wheel 1 that matches the guide bar. Two nylon guide plates 14 are installed on the left and right sides of the upper baffle 4 and the frame 5, which makes the compression of the pusher head 6 more stable and has better guidance, significantly improving the motion accuracy and durability of the equipment under continuous heavy load conditions. The upper opening of the pusher head 6 is designed with two detachable blades 7. When the pusher head 6 moves forward, it cuts long materials in the material box. The front end of the pusher head 6 is designed with a 70x30mm wire groove 8. The blades 7 can cut long materials in the material box, making the compressed material have a regular shape, which is more convenient for bundling and processing, and is easy to use.
