Description

Technical Field

[0001] The utility model belongs to the technical field of resin tile crushing, in particular to a flame-retardant resin synthetic tile recycling and shredding device. Background Art

[0002] The current market demand for resin tiles is huge. Although the technology has been continuously improved, it is still inevitable that many defective products will be produced, and cracks will appear during the processing. The above defective products are usually crushed and then reused. Since there are many types of resin tiles, such as large plates, long strips, small pieces, etc., the processing process will also be different. Generally, resin tiles with larger areas will be crushed once or twice to achieve the best crushing effect.

[0003] After searching, the prior art publication number CN 116572431 A is an automatic recycling and crushing device for waste resin tiles. The waste resin tiles are screened and preliminarily crushed in the first crushing chamber. The crushed waste enters the second crushing chamber and is heated and softened while being crushed by the intermeshing blades that rotate and move at high speed. By cutting and crushing the waste with the intermeshing blades after softening, the crushing efficiency is improved, and a large amount of dust generated by the waste crushing is avoided. This scheme performs primary and secondary crushing by the first crushing unit and the second crushing unit to improve the crushing effect. The crushing roller is used for crushing and the edge blade is used in combination with the intermeshing blade for crushing. Furthermore, the resin tiles will become relatively soft after preheating, and then there will be inclusions between the edge blade and the intermeshing blade during crushing, and there will be inclusions between the protrusions on the crushing roller, which will affect the overall crushing effect.

[0004] After searching, the prior art announcement number CN 220390024 U is a waste collection device for synthetic resin tile processing. When the resin waste is crushed, the resin waste that is not completely crushed will not fall through the discharge port below, but will be repeatedly crushed in the crushing box before passing through the screen net and falling onto the connecting slide plate, ensuring that in the subsequent extrusion process, the extrusion efficiency will not be reduced or even the extrusion components will be damaged due to the excessive volume of the waste. This solution uses a crushing roller to continuously crush the resin tiles in situ until all of them pass through the screen net. The above method has a slow crushing efficiency, and the vertical setting of the crushing roller is not good. The same rotation speed will produce the same efficiency for the crushing of the newly fed material on the top and the crushing of the resin tiles that have not passed through the screen at the bottom. However, the initial crushing speed or rotation speed required for the newly fed material to crush the support blocks is different from that for the bottom resin tiles to be crushed into a state that can pass through the screen. The new feed can be initially crushed at a slower speed, while the resin tile particles at the bottom that need to pass through the screen require a faster speed and increased power. Therefore, at the same speed, when the bottom end of the crushing roller continues to act on the resin tiles that have not passed through the screen at the bottom, the subsequent newly fed resin tiles will quickly accumulate on the top, affecting the feeding and crushing efficiency. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a flame-retardant resin synthetic tile recycling and reuse shredding device, in which the shredding mechanism can be adjusted to change the shape to avoid the situation where the resin tile particles are mixed and affect the shredding efficiency.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1) The crushing mechanism includes a pair of crushing rollers, namely the first crushing roller and the second crushing roller. The second crushing roller can drive the lead screw to rotate through the fifth motor and then push the second crushing roller to slide along the through groove to adjust the spacing between the first crushing roller and the second crushing roller, so that resin tiles of different types and sizes can be crushed; further, the second motor can drive the bidirectional lead screw to rotate, and then the fixed seat and the first arm can drive the top plate to touch or retract the inner cavity of the crushing roller, so as to switch the state of the top plate being ejected as a convex roller and the top plate being retracted as a smooth roller, which can meet the needs of primary crushing and secondary crushing. The convex roller state of the top plate can initially crush the resin tiles into larger resin tile pieces; the smooth roller state of the top plate retracted can The resin blocks are crushed for the second time. The crushing roller in the smooth roller state can squeeze and crush the large resin tiles into smaller particles to pass through the screen plate smoothly. The speed of the crushing roller can also be adjusted according to the needs of the two crushings. The optimal speed is used to carry out targeted crushing of different batches of resin tiles. The initial crushing speed is low, and the secondary crushing speed is high. This avoids the situation that when only one-time crushing is used, the bottom resin tiles need to be crushed and filtered as soon as possible and the top resin tiles need to be crushed at a relatively slow speed at one speed. Therefore, the crushing efficiency can be improved by crushing in batches twice. At the same time, the retraction effect of the top plate can remove the support force of the resin tiles mixed between the top plates when ejected, and then clean up the inclusions of the resin tiles, ensuring the cleanliness of the crushing roller surface and the crushing effect.

[0014] 2) The vibration mechanism can strike and vibrate the "human" shaped screen plate in sequence, thereby improving the screening efficiency of the screen plate through vibration. The further lifting mechanism will lift a certain amount of resin tiles accumulated after screening to the feed port for secondary crushing, completing the process of primary crushing and secondary crushing. The two crushing processes can avoid the continuous accumulation of crushed materials compared to the one-time mixed crushing process, and can carry out orderly crushing processing; among them, the oil cylinder can control the inclination angle of the frame and the conveyor belt to accurately feed the material to the feed port. After the lifting is completed, the frame is reset to keep the frame away from the feed port, which can effectively ensure the smooth filling of the feed port. BRIEF DESCRIPTION OF THE DRAWINGS
