Description

Technical Field

[0001] This utility model relates to a waste material crushing device, and more particularly to a waste material crushing device used in the processing of fireproof partitions. Background Technology

[0002] During the processing of fireproof boards, various chemical fiber raw materials need to be crushed and mixed. During crushing, some fibers may remain clump together without being broken, making it impossible to mix them evenly with other fibers. Therefore, these clumps need to be removed and crushed again. However, whole-bag crushing devices have large gaps in their structure, resulting in low crushing efficiency for scattered residue. Furthermore, fibers generate static electricity during transportation, causing them to adhere to the machine and affecting its operation. Therefore, it is crucial to prevent static electricity generation during crushing. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a waste material crushing device with high crushing efficiency and avoids the generation of static electricity in fibers.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a waste material crushing device, including a frame, a conveyor belt on the frame, a feeding roller group at the end of the conveyor belt, the feeding roller group consisting of two feeding rollers symmetrically arranged vertically, the surface of the feeding rollers being evenly distributed with anti-slip textures, a hook roller being provided behind the feeding roller group, the surface of the hook roller being distributed with protruding spikes, an exhaust port being provided above the hook roller, the exhaust port being connected to a collection box, and a discharge port being provided at the bottom of the collection box.

[0005] The frame is equipped with a spray frame, the spray frame is equipped with spray pipes, and the ends of the spray pipes are equipped with multiple nozzles. The spray pipes are connected to a water tank through a water pump.

[0006] The conveyor belt is symmetrically equipped with baffles on both sides, and each baffle is equipped with a rubber sheet. The bottom of the rubber sheet is in contact with the conveyor belt. A connecting strip is provided above the rubber sheet, and a dustproof plate with a dustproof net on its surface is supported on the connecting strips of the two side baffles.

[0007] Its beneficial effects are as follows: The structure of this utility model is reasonable and ingenious. The leftover material from processing fireproof boards is placed on the conveyor belt, and after being conveyed to the feeding roller group, it is clamped and moved backward at a set speed. The spikes on the hook roller break the leftover material. The broken fibers are sucked into the collection box by the exhaust port and fall from the discharge port. It can efficiently process small and compact leftover materials. The spray frame sprays water on the leftover material on the conveyor belt to increase the ambient humidity to eliminate static electricity on the leftover material and prevent static electricity-generating leftover material from adsorbing onto the equipment. Attached Figure Description

[0008] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0009] Figure 1 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0011] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] like Figure 1 The waste material crushing device shown includes a frame 1, on which a conveyor belt 3 is mounted. At the end of the conveyor belt 3 is a feed roller assembly 6, consisting of two symmetrically arranged feed rollers with uniformly distributed anti-slip textures on their surfaces. Driven by a motor, the feed rollers, as they rotate, clamp the waste material transmitted from the conveyor belt 3 and transfer it backward. Behind the feed roller assembly 6 is a hook roller 7, with protruding spikes on its surface. One end of the waste material is clamped by the feed roller assembly, while the other end is hooked by the spikes and rotated upward, gradually peeling off the agglomerated waste material. Above the hook roller 7 is an exhaust port 9, connected to a collection box 8. The bottom of the collection box 8 has a discharge port. The small pieces of waste material that have been peeled off are sucked into the collection box 8 through the exhaust port 9 and fall from the discharge port, continuing to be conveyed to a mixing device for mixing, thus achieving efficient crushing of smaller waste materials.

[0014] A spray frame 10 is installed on the frame 1, and a spray pipe is installed on the spray frame 10. Multiple nozzles are installed at the ends of the spray pipes, and the spray pipes are connected to a water tank via a water pump. The spray pipes on the spray frame 10 spray water onto the residual material on the conveyor belt 3 to increase its humidity, thereby removing static electricity from the residual material and preventing the fiber lint from the residual material from flying and sticking to the working equipment, which could cause damage to the equipment.

[0015] The conveyor belt 3 is symmetrically equipped with baffles 2 on both sides. Each baffle 2 has a rubber sheet 4 on it. The bottom of the rubber sheet 4 contacts the conveyor belt 3, blocking the gap between the conveyor belt 3 and the baffle 2, preventing residual material from entering the gap and causing the conveyor device to jam. A connecting strip 5 is provided above the rubber sheet 4. A dustproof plate with a dustproof netting is mounted on the connecting strip 5 on both sides of the baffles 2. The dustproof plate can prevent dust from falling on the residual material and prevent the residual material lint from spreading everywhere. The dustproof plate can be directly removed for easy and quick maintenance of the device.

[0016] A cover plate is connected to the exhaust port 9 by a pin. The two ends of the cover plate rest against the frame 1, so that the cover plate covers the top of the feed roller group 6. This can concentrate the air force of the exhaust port 9, so that the fibers on the hook roller 7 are sucked away as much as possible, avoiding accumulation and preventing the fibers from flying.

[0017] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
