Technical Field

[0001] The invention relates to the technical field of plastic foam processing and crushing, and in particular to a foam processing and crushing device. Background Art

[0002] Plastic foam is a type of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, and dielectric properties are better than the base resin, and it has a wide range of uses. Plastic foam can be divided into closed-cell foam plastics, open-cell foam plastics and reticulated foam plastics. All the pores of closed-cell foam plastics are almost unconnected, all the pores of open-cell foam plastics are almost connected, and reticulated foam plastics have almost no pore walls.

[0003] Foam materials are widely used in packaging, construction and other fields, but their disposal has always been a technical difficulty. Existing foam crushing devices mostly use a single-stage crushing structure, which has problems such as low efficiency, uneven crushing particles, and high energy consumption.

[0004] For example, traditional crushers only cut once with a rotating cutter, resulting in large pieces of foam remaining and requiring secondary processing; some equipment adopts a multi-stage series structure, but has defects such as large size, high cost, and complex maintenance. In addition, blockage is prone to occur during the feeding process, affecting continuous operation. Therefore, there is an urgent need for an efficient, energy-saving, and compact two-stage crushing device to improve the efficiency of foam recovery and processing. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a foam processing and crushing device, which solves the problems of low efficiency, high energy consumption, and easy clogging of traditional equipment through innovative designs such as two-stage crushing, linked feeding, negative pressure conveying and gradually shrinking crushing gap. While improving the crushing uniformity and processing efficiency, it achieves the comprehensive performance of compact structure and stable operation, and is suitable for various plastic foam recycling scenarios to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

When the pusher retreats, the feed port opens and the material enters the push chamber. When the pusher advances, the feed port closes to prevent the material from splashing back. This design ensures continuous and uniform feeding and avoids the blockage problem caused by material accumulation or backflow in traditional equipment.

[0017] Preferably, the foam conveying pipe comprises a suction pipe connected to the outer wall of one side of the foam board crushing chamber, a pushing pipe fixedly connected to one end of the suction pipe, and a negative pressure air duct fixedly connected to the outer wall of the bottom of the pushing pipe.

[0019] Preferably, the pushing member comprises a pushing rod slidably connected to the inner wall of one end of the pushing tube, and a pushing plate welded to the outer wall of one end of the pushing rod, wherein the pushing plate is slidably connected to the inner wall of the pushing tube.

[0020] Through the above scheme, the push rod is driven by the connecting rod, and the push plate reciprocates in the push tube to push the crushed materials to the secondary crushing assembly.

[0021] Preferably, the buffer member includes a baffle slidably connected to the inner wall of the push tube and a spring fixedly connected between the baffle and the push tube, wherein when the spring is in a relaxed state, the baffle is located on the shorter side of the connection between the suction tube and the push tube.

[0022] Through the above scheme, the baffle of the buffer member can block the broken materials under the action of the spring, preventing the broken materials from flowing back to the end of the push pipe and causing blockage, thereby controlling the broken materials to flow back into the suction pipe normally.

[0024] Through the above solution, the second servo motor drives the rotating rod to drive the conical crushing disk to rotate at high speed. As the gap between the conical crushing disk and the crushing cover gradually decreases, the crushing block can squeeze and shear the crushed material, and finally the powder falls into the storage tank.

[0025] Preferably, a feed frame is welded to the top outer wall of the body, and an inclined feed plate is welded to the top of the feed frame, a feed port is opened on the top outer wall of the body located inside the feed frame, and the inclined baffle plate is slidably connected to the inner wall of the feed port.

[0029] The beneficial effects of the present invention are:

[0030] 1. The foam processing and crushing device of the present invention adopts a double-stage crushing design combining pre-crushing and secondary crushing. The horizontal cutting knife and the vertical cutting knife of the pre-crushing component cut the foam in multiple dimensions to form uniform fragments. The secondary crushing component uses the gradually shrinking gap between the conical crushing disk and the crushing cover to perform secondary extrusion and shearing on the fragments, which significantly improves the crushing efficiency and finally obtains powder with uniform particle size, avoiding the problem of residual large pieces caused by traditional single-stage crushing.

[0082] 2. Pushing and feeding linkage control

[0083] The reciprocating screw 43 at the end of the worm 42 drives the internal thread plate 46 and the push piece 47 to reciprocate along the guide groove 10. At this time, the sawtooth block 472 of the push seat 471 can squeeze the crushed material in the process of approaching the pre-crushing component 45, so that it can tightly enter the foam board crushing chamber 3. And when the push piece 47 retreats, the oblique material baffle plate 48 will move to open the feed port 9, and new materials will enter the machine body 1 at this time. When the push piece 47 moves forward, the material baffle plate closes, forming a closed-loop control of continuous feeding and crushing.

[0084] 3. Material conveying and secondary crushing

[0085] The pre-crushed crushed material enters the pusher tube 612 through the suction tube 611, and the negative pressure air duct 613 blows toward the pusher tube 612 to form a negative pressure auxiliary suction. Since the pusher rod 621 of the pusher 62 is driven by the connecting rod 5, the pusher plate 622 pushes the crushed material to the secondary crushing assembly 66. The second servo motor 68 drives the conical crushing plate 662 to rotate at a high speed, and the gradually shrinking gap between the crushing plate and the crushing cover 661 causes the crushed material to be subjected to multi-stage shearing and extrusion, and finally refined into powder and fall into the storage tank 67. With the repeated blowing of the negative pressure air duct 613, the crushed powder foam will be continuously discharged from the bottom of the storage tank 67.

[0086] 4. Anti-backflow and sealing design

[0087] The baffle 631 of the buffer 63 blocks the crushed material from flowing back to the end of the push tube 612 under the action of the spring 632, preventing the crushed material from flowing back to the end of the push tube 612 and causing blockage, thereby controlling the crushed material to flow back normally into the suction tube 611. The size adaptation design of the sealing plate 12 and the chute 11, as well as the close fit between the guide strip 473 and the guide groove 10, effectively prevent material leakage and ensure the sealing performance and operation stability of the equipment.
