Description

Technical Field

[0001] The utility model relates to the technical field of shredders, and specifically relates to a screen for a shredder. Background Art

[0002] A shredder is a machine used for coarse crushing, generally used to process unprocessed raw materials or scraps in the recycling and regeneration industry to make their sizes smaller. Compared with other crushers, it has a low cutter shaft speed, low noise, and low energy consumption. A shredder is a machine used for fine crushing, generally used to process unprocessed raw materials or scraps to make their sizes smaller. A typical example is shredding the scraps of plastics or rubbers and then melting and granulating them as raw materials to remanufacture plastic bottles, tires, trash cans, etc. Shredders are applied in the plastic recycling and regeneration industry and are often used for crushing large-caliber PE plastic pipes, bundled plastic films, large stacks of plastic sheets, and head materials of waste products. Currently, when people screen the materials in a shredder, they often use a screen.

[0003] The prior art patent document with the publication number CN220144020U provides a screen for a shredder. In this device, teeth are arranged in a staggered manner on both sides of the screen part to form a continuous Z-shaped groove structure, and a plurality of the teeth in a column in the axial direction of the screen body face the same side. The teeth on the partition ribs are distributed in a staggered manner towards both sides, and the width of the teeth compensates for the width of the partition ribs. This avoids the situations of material hanging and blocking caused by the inability of materials to fall due to lack of force, improves the passing rate of the screen materials, and ensures the normal operation of the overall equipment.

[0004] However, in the prior art, when replacing or cleaning the screen of a shredder, the screen often needs to be completely disassembled. As a result, the screen and the matching screen frame structure are heavy, which increases the difficulty of cleaning the screen by people and reduces the practicability of screen replacement. Therefore, we need a screen for a shredder. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a screen for a shredder to solve the existing problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A screen for a shredder includes a screen frame. A screen assembly is arranged on one side of the screen frame. An installation assembly is fixedly connected to one side of the screen frame. A top plate is bolted to the top of the installation assembly. The screen assembly includes a limiting groove. A spring is fixedly connected inside the limiting groove. One end of the spring is fixedly connected to a fixing frame. A screen is snap-fitted to one side of the fixing frame. A handle is fixedly connected to one side of the screen.

[0007] Preferably, the screen frame is fixedly structured with the spring through a limiting groove, and the number of springs is three, and the three springs are equally spaced in the limiting groove.

[0008] Preferably, the screen frame is elastically structured with the fixed frame through a spring, and the spring is arranged between the screen frame and the fixed frame.

[0009] Preferably, the screen is fixedly structured with the handle, and the handle is arranged higher than the screen frame.

[0010] Preferably, the installation assembly includes side plates. A first bolt is arranged on one side of the side plates. A chute is opened inside the side plates, and a sliding plate is slidably connected inside the chute. A positioning hole is opened inside the sliding plate. A second bolt is arranged on the top of the top plate. The top plate is fixedly structured with the shredding mechanism through the second bolt, and one end of the second bolt penetrates through the top plate and extends into the shredding machine for connection.

[0011] Preferably, the side plates are fixedly structured with the top plate through the first bolt, and one end of the first bolt penetrates through the side plates and is connected with the nut through the positioning hole on the top plate.

[0012] Preferably, the side plates are slidably structured with the sliding plate through the chute, and the shape and size of the chute match those of the sliding plate. Moreover, the outer diameter of the sliding plate matches the inner diameter of the chute, and the outer wall of the sliding plate is in close contact with the inside of the chute.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The screen frame is provided to install multiple screens. By pulling the handle held by hand, the handle can drive the screen to move to one side, enabling the screen to push the fixed frame in the limiting groove. Supported by the spring, it is convenient to support and limit the fixed frame, and it can meet the needs of disassembling and installing the screen. The screen in a single area can be disassembled and cleaned separately, improving the convenience of replacing or using the screen. There is no need to disassemble the entire screen, enhancing the practicality of the screen.

[0015] 2. The side plates on the screen frame can be docked with the top plate, and the side plates can be stuck on the outer wall of the sliding plate on the top plate by relying on the chute inside. The chute can slide along the outer wall of the sliding plate on the top plate, thereby achieving the installation of the screen frame. After installation, the side plates and the top plate can be fixedly installed together by relying on the provided first bolt, further strengthening the fixing effect between the side plates and the top plate, and facilitating the installation of the screen on the shredding machine.
