Then, a specific structure of the material receiving mechanism 302 is disclosed, the material receiving mechanism 302 includes side grooves 331 formed in two sides of the first side pressing plate 322 and the second side pressing plate 323, side rollers 332 are rotatably arranged in the four side grooves 331, material receiving grooves 333 are formed in the first side pressing plate 322 and the second side pressing plate 323, the side grooves 331 on two sides of the first side pressing plate 322 are communicated with the material receiving grooves 333 in the first side pressing plate 322, the side grooves 331 on two sides of the second side pressing plate 323 are communicated with the material receiving grooves 333 in the second side pressing plate 323, and the side rollers 332 have certain gravity and can improve the fixing effect of the molded plastic body 10 while not affecting the sliding of the first side pressing plate 322 and the second side pressing plate 323.
Referring to fig. 8, the receiving slots 333 are respectively formed in the first side pressing plate 322 and the second side pressing plate 323, meanwhile, the side slots 331 on two sides of the first side pressing plate 322 are mutually communicated with the receiving slots 333 in the first side pressing plate 322, and the second side pressing plate 323 is the same as the first side pressing plate, so that the side rollers 332 roll on the surface of the molding plastic body 10 during the operation of the device, in this process, the side rollers 332 can bring impurities on the surface of the molding plastic body 10 into the side slots 331, and because the side slots 331 are communicated with the receiving slots 333, when the side rollers 332 continuously rotate, the impurities can be thrown into the receiving slots 333, thereby realizing the collection of the impurities such as fine dust on the surface of the molding plastic body 10.
It should be noted that, the side of the first side pressing plate 322 and the second side pressing plate 323 far away from the cross supporting rod 321 are provided with discharge ports, and the cover plates of the two discharge ports are in sealing clamping connection with the first side pressing plate 322 and the second side pressing plate 323, so that the material collecting groove 333 is cleaned after the device stops running.
And finally, the concrete structure of the crushing mechanism 2 is disclosed, the crushing mechanism 2 comprises a crushing box 22 positioned at the bottom of the workbench 1, two discharging cavities 21 are formed between two sides of the conveying belt 11, which are close to the inner wall of the workbench 1, and the inner wall of the workbench 1, wherein a crushing roller 23 is rotatably arranged in the crushing box 22, the outer wall of the crushing box 22 is fixedly connected with a motor, a rotating shaft of the crushing roller 23 is fixedly connected with an output shaft of the motor, and the crushing box 22 can be used for overturning and discharging.
As shown in fig. 4, with the sliding cutting of the cutter body 314, the first side pressing plate 322 and the second side pressing plate 323 can clamp the cutting periphery of the molding compound body 10 in real time, when the cut large scrap is separated from the cutting molding compound body 10, the large scrap has a gravity effect in view of the fact that the large scrap itself has, and the clamping position after cutting is moved, so that the scrap does not have the characteristic of clamping at both sides, and the scrap can fall into the crushing box 22 from the side end of the conveying belt 11 to be crushed (if the scrap body is large, the manual auxiliary falling can also be performed).
When the bulk waste generated by cutting the molding compound body 10 falls into the crushing box 22 from the blanking cavity 21, the crushing roller 23 which is rotatably arranged inside the crushing box 22 starts to act, the motor fixedly connected with the outer wall of the crushing box 22 is started, the output shaft of the motor drives the rotating shaft of the crushing roller 23 to rotate, the crushing roller 23 extrudes and crushes the bulk waste which falls into the crushing box 22 in the rotating process, and after the crushing work is finished, the crushing box 22 can overturn and discharge, and the crushed waste is poured out for subsequent treatment or recycling.
Because there is certain clearance between first side clamp plate 322 and second side clamp plate 323 and the cutting seam, consequently, in order to promote the collection condition of cutting impurity, the both sides of first side clamp plate 322 and second side clamp plate 323 are all fixedly connected with aggregate plate 4.
The improvement is that as shown in fig. 6, the collecting plate 4 can scrape impurities to the side roller 332 in the moving process of the first side pressing plate 322 and the second side pressing plate 323, when the impurities are scraped to the side roller 332, the side roller 332 can collect fine dust impurities more easily, more cutting impurities can be collected, and the collection efficiency of the cutting impurities is improved.
Considering the driving condition of the fine dust generated in the cutting process by the side rollers 332, in order to further improve the collecting effect of the fine dust, the surfaces of the four side rollers 332 are all sleeved with the sticky sleeves 5 for sticky adsorption of the impurity dust.
The improvement is that as shown in fig. 8 and 9, the side roller 332 contacts with the molding compound body 10 in the rotation process and drives surrounding air to flow, so that fine dust generated in the cutting process is more easily attached to the side roller 332, the adhesive sleeve 5 increases the adsorption capacity of the side roller 332 to the fine dust, so that more fine dust can be adsorbed and finally brought into the side groove 331 through the rotation of the side roller 332, wherein the adhesive sleeve 5 can be made of a sticky silica gel material, and can be better attached to the surface when contacting with the SMC molding compound body 10, thereby more effectively adhering the fine dust, simultaneously, the silica gel material has better heat resistance and wear resistance, can bear a certain temperature and friction in the cutting process of the molding compound, is not easy to damage, and ensures the service life of the adhesive sleeve 5 and the continuous adsorption capacity to the fine dust.
Because the sticky impurities are adhered by the sticky sleeve 5, the removing effect of the impurities is easily affected, and then the collection condition of the side roller 332 on fine dust is affected in the whole flow, therefore, the scraper blades 6 are fixedly connected to the tops of one sides of the two material collecting grooves 333, which are close to the side grooves 331, and the scraper blades 6 are used for scraping the impurity dust adhered to the surface of the side roller 332 when the side roller 332 rotates.
The improvement lies in that, combining with the illustration of fig. 10, the top of one side of two receiving tanks 333 close to the side tank 331 is fixedly connected with a scraper blade 6, when the side roller 332 rotates, the scraper blade 6 can scrape the impurity dust stuck on the surface of the side roller 332, thus ensuring that the surface of the side roller 332 always keeps better adsorption capacity, continuously and effectively collecting fine dust, the scraped impurity dust can fall into the receiving tanks 333, realizing the centralized collection and treatment of the fine dust, and further ensuring the cleanliness and the fine dust collection efficiency in the whole cutting process.
In order to reduce the impurity falling between the first side pressing plate 322 and the second side pressing plate 323, the inner walls of one side of the first side pressing plate 322 and one side of the second side pressing plate 323, which are close to the cutter body 314, are provided with drainage walls 7.
The improvement lies in that as shown in fig. 8, the drainage wall 7 is in an arc state, and is used for guiding the fine dust splashed when the cutter body 314 cuts, and when the cutter body 314 cuts the molding plastic body 10, the fine dust splashed can be generated, and in combination with fig. 11, the arc-shaped drainage wall 7 can change the movement direction of the fine dust, so that the fine dust can accurately fall on the outside of the collecting plate 4, thereby avoiding the accumulation of impurities between the first side pressing plate 322 and the second side pressing plate 323, and being beneficial to timely collecting and processing the fine dust.
