Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and particularly to a raw material crushing equipment for plastic production. Background Art

[0002] Plastic raw materials are the basic materials for plastic product production, and their main component is synthetic resin. And during the plastic processing process, in order to facilitate subsequent reuse or further processing, it is usually necessary to crush raw materials whose form or size does not meet the requirements.

[0003] In the recycling link, common plastic raw materials include waste plastic bottles, plastic barrels, as well as scraps and sprue materials generated during processes such as injection molding, extrusion, and blow molding. After the materials are usually centrally collected, they are continuously fed into the crushing device through a conveying device for processing. This makes it so that in the actual operation process, recycled plastics are directly fed into the crushing equipment in a whole batch manner through a conveyor, and thus lack a necessary pre-treatment link. Since there is still liquid remaining in some waste plastic bottles, and there may be large plastic lumps in the scraps, this batchwise direct crushing method has many problems. On the one hand, the liquid is not effectively separated and easily enters the interior of the crushing equipment together with the materials, especially the cutting tool area of the crushing equipment, resulting in the liquid mixing and adhering with the crushing residues, and then causing equipment blockage and generating odors; on the other hand, putting in too much raw materials at one time or the materials containing large lumps are likely to cause blockage of the feeding port and material accumulation, which not only affects the crushing efficiency, but may also reduce the stability and safety of the equipment operation.

[0004] Therefore, there is an urgent need to design a raw material crushing equipment for plastic production that has a function of pre-treating residual liquid and can achieve continuous batch processing, so as to improve the overall crushing efficiency and ensure the stability and safety of the equipment operation.

Detailed implementation manners

[0028] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0029] Embodiment 1: A raw material crushing device for plastic production, as Figures 1 - 5 and Figures 7 - 9 shown, includes: A frame 1, with a machine frame 10 fixedly arranged on the front side of the frame 1. Inside the machine frame 10, electric crushing rollers 11 are symmetrically installed left and right. The electric crushing rollers 11 are used for crushing the pre-treated plastic products. The conveying and cutting mechanism 2, the conveying and cutting mechanism 2 includes a casing 21 which is fixedly arranged obliquely at the rear side of the frame 1, so that the casing 21 has a ramp structure from top to bottom, and a feeding hopper 22 communicating with the machine frame 10 is arranged at the upper end of the casing 21 for receiving the discharged plastic products after pretreatment. A feeding hopper 23 is communicated with the lower side of the casing 21 as the feeding inlet of the plastic products to be processed. A conveyor 24 for conveying plastic products is arranged inside the casing 21, so that the plastic products to be processed are smoothly conveyed from bottom to top, providing guarantee for subsequent cutting and batch discharging processes. And partition plates 25 are arranged at intervals on the conveyor belt of the conveyor 24. Liquid leakage holes 251 are opened on the partition plates 25. The arrangement of the liquid leakage holes 251 enables the liquid generated during the cutting process to be discharged smoothly downward. And a multi-saw blade cutting group 26 is installed in the casing 21. The partition plates 25 have equally spaced plates, and the intervals between the plates are for the blades of the multi-saw blade cutting group 26 to pass through, so as to facilitate efficient and continuous cutting of plastic products; The blowing mechanism 3 for liquid removal, which is arranged on the casing 21 and above the multi-saw blade cutting group 26; Specifically, through the coordinated cooperation of the conveying and cutting mechanism 2 and the blowing mechanism 3, the segmented cutting and preliminary quantitative separation of plastic products are realized, and the pretreatment of drying and segmenting plastic products is achieved, so as to facilitate subsequent batch crushing operations. At the same time, the arrangement of the liquid leakage holes 251 and the overall inclined trend design of the conveyor 24 effectively ensure the effective discharge of the liquid inside the cut plastic segments, avoiding the influence of liquid accumulation on the crushing efficiency. The arrangement of the blowing mechanism 3 further dries the plastic segments, thus completing a complete pretreatment process; In this way, compared with the traditional centralized feeding and direct processing methods, this solution adopts a pretreatment method of quantitative batching, cutting first and then crushing, significantly improving the operating efficiency of subsequent equipment, reducing the failure rate, realizing the integration of the process, simplifying the operation steps, and optimizing the overall processing effect.

[0030] The weighing mechanism 4, the weighing mechanism 4 includes a mounting plate 41 arranged on the top of the machine frame 10. Two groups of vertical plates 411 symmetrically arranged front and back are fixedly arranged at the bottom of the mounting plate 41. The front and rear vertical plates 411 are respectively attached to the side walls on the same side of the machine frame 10. Guide grooves 412 are opened on the vertical plates 411. Electric push rods 42 are symmetrically arranged left and right on the mounting plate 41. The telescopic ends of the two electric push rods 42 are connected with a retaining shell 43. Arc-shaped plates 44 are hinged at the bottoms of the retaining shells 43. By the telescopic operation of the electric push rods 42, the retaining shell 43 and the arc-shaped plates 44 are driven to move up and down. Fitting ends 441 slidably embedded in the adjacent guide grooves 412 are respectively arranged on the front and rear sides of the arc-shaped plates 44; Specifically, the width of the upper section of the guide groove 412 is wider than that of the lower section, and the upper sections of the left and right opposite guide grooves 412 are provided with an oblique angle on the opposite side, so that the corresponding fitting end 441 of the arc-shaped plate 44 can be tilted and rotated along the oblique angle. This makes the rotation and tilting tendency of the arc plate 44 limited by the moving height. When the fitting end 441 drops to the narrow groove area, it is stably limited in the groove body and maintains a horizontal state, so that the arc plate 44 is in a flat closed state (see Figure 8 ), thereby closing the feed channel; on the contrary, when the engaging end 441 is located in the wide groove area, it is less restricted and, under the action of its own gravity, it tilts and expands along the oblique angle, driving the arc-shaped plates 44 on both sides to open (see Figure 9 ), to allow the plastic product to fall smoothly into the interior of the frame 10; Through the above structural design, the quantitative feeding of plastic products in batches can be realized, effectively preventing the blockage problem caused by a large amount of material being fed at one time, and improving the continuity and stability of subsequent crushing operations.

[0031] like Figures 2 - 4 As shown, the multi-saw blade cutting group 26 includes a drive shaft 261 that rotates at intervals between the left and right sides of the casing 21, and a plurality of circular saw blades 262 are arranged at intervals on the drive shaft 261. Two adjacent groups of circular saw blades 262 are staggered to improve cutting efficiency and uniformity, and mutually meshing drive gears 263 are provided at the ends of the drive shaft 261. A drive motor 264 with an output end connected to the shaft end of one of the drive shafts 261 is installed on the right side of the casing 21.

[0032] like Figure 2 、 Figure 3 and Figure 5 As shown, the blowing mechanism 3 includes a turbine fan 31 fixedly mounted on the bottom of the housing 21. The air outlet of the turbine fan 31 is connected to a three-way frame 32. The left and right ends of the three-way frame 32 extend to the two sides of the housing 21 respectively. The left and right ends of the three-way frame 32 are respectively arranged and connected with four air outlet frames 33. The air outlet frames 33 are connected to the housing 21, and a centralized frame 36 for collecting waste liquid is provided at the bottom of the housing 21, thereby achieving effective drying of plastic products and avoiding the problem of plastic agglomeration caused by waste liquid residue. like Figure 5 As shown, the blowing mechanism 3 also includes a motor 34 installed on the tee frame 32. The output end of the motor 34 is connected to a dial plate 35 located inside the tee frame 32. The end of the dial plate 35 contacts and cooperates with the side wall of the main channel of the tee frame 32. The motor 34 drives the dial plate 35 to rotate, which can periodically change the airflow direction of the main channel, so that the airflow intermittently flows to the branch channels on both sides, thereby improving the blowing efficiency and avoiding the problem of uneven local drying.

[0033] During use, first ensure that the device is placed stably. Subsequently, the plastic products to be processed are put in through the feed hopper 23, so that they enter the interior of the machine casing 21 and are placed on the conveyor belt of the conveyor 24. Driven by the conveyor 24, the plastic products are conveyed from bottom to top, and a partition plate 25 is provided on the conveyor belt, which can divide the incoming plastic products into areas, realizing preliminary quantitative batching.

[0034] As the conveyor belt runs, the plastic products are sent to the area of the multi-saw blade cutting group 26. Driven by the drive motor 264, the connected drive shaft 261 rotates, driving the drive gear one 263 at the end to rotate. The adjacent drive gears one 263 mesh with each other, enabling the synchronous operation of each drive shaft 261, thereby driving the circular saw blades 262 thereon to rotate at high speed and perform cutting on the conveyed plastic products. After cutting, the plastic products are in segments, and the residual liquid inside flows out accordingly, drips through the liquid leakage holes 251 on the conveyor belt, and converges to the centralized frame 36 at the bottom along the inclined direction of the conveyor belt, and is finally discharged uniformly, realizing the effective recovery and discharge of the residual liquid. At the same time, the segmented plastic products are more convenient for subsequent crushing treatment, effectively avoiding the risks of blockage and material accumulation.

[0035] Immediately afterwards, the cut plastic products continue to be conveyed to the blowing mechanism 3 area. The turbine fan 31 generates air flow, and the air flow circulates into the interior of the three-way frame 32, and respectively enters the interior of the machine casing 21 from the air outlet frame 33 through the branch channels of the drive shaft 261 to blow the plastic segments on the conveyor 24. At the same time, the motor 34 is started to drive the deflector 35 to rotate, periodically deflecting the air flow in the main channel of the three-way frame 32, and cooperating with the branch channels on both sides to form a two-way air flow that alternates left and right, further removing the residual liquid adhering to the surface of the plastic products and ensuring the effect of subsequent crushing operations.

[0036] Subsequently, the dried plastic segments fall into the machine frame 10 through the blanking hopper 22. At this time, the arc plates 44 are in an open state: the two arc plates 44 are located in the wide slot of the guide groove 412, and the fitting end 441 is inclined due to the bevel angle, making the arc plates 44 in an open state, facilitating the plastic segments to pass smoothly through the interval channel between the two arc plates 44 and then fall between the lower electric crushing rollers 11.

[0037] When a certain amount of plastic products have fallen, the electric push rod 42 is started to push the retaining shell 43 and the arc plates 44 as a whole to move downward. The fitting end 441 moves downward along the guide groove 412 and enters the narrow slot section, returning to a straight state, prompting the two arc plates 44 to close, temporarily blocking the falling of the upper plastic segments, and realizing batch quantitative control. At the same time, the closed arc plates 44 continue to move downward and are used as pressing plates to apply pressure to the plastic segments being crushed below, prompting them to closely adhere to the electric crushing rollers 11, thereby improving the crushing efficiency and effect.

[0038] Finally, the plastic fragments that have completed the crushing process are discharged from the bottom of the machine frame 10, and the crushing process of the entire plastic product is completed.

[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 3 and Figure 6 shown, it further includes a filter frame 5 connected to the bottom of the casing 21. The filter frame 5 is located at a lower position of the casing 21, and an infusion pump 51 is also installed at the bottom of the casing 21. A spray pipe 52 extending into the interior of the filter frame 5 is connected to the liquid outlet of the infusion pump 51, and spiral spray nozzles 53 are rotatably arranged at intervals on the spray pipe 52.

[0040] During the operation of the conveyor 24, the infusion pump 51 is started synchronously to convey the cleaning liquid or clean water to the spray pipe 52 and the spiral spray nozzles 53. Under the action of water pressure, when the water flow sprays out from the spiral spray nozzles 53, it drives the nozzles themselves to rotate, realizing uniform coverage spraying, so as to efficiently clean the surface of the conveyor belt running in rotation, ensure its cleanliness, and further guarantee the overall effect of the pretreatment of plastic products.

[0041] As Figure 1 , Figure 7 and Figure 10 shown, it further includes a cleaning mechanism 6. The cleaning mechanism 6 includes an assembly shell 61 arranged on the front side of the machine frame 10. A hot air blower 62 is installed on the assembly shell 61. Two delivery pipes are connected to the air outlet of the hot air blower 62. One guide frame 63 connected to the end of the adjacent delivery pipe is respectively communicated on the left and right sides of the machine frame 10. The air outlets of the guide frames 63 are respectively aligned with the electric crushing rollers 11 on the same side, ensuring that the flowing gas directly blows to the surface of the corresponding electric crushing roller 11, so that the air flow generated by the guide frame 63 can fully cover the electric crushing roller 11. This not only further effectively dries the plastic sections, improves the overall drying effect, but also synchronously blows the fragments stuck inside the electric crushing roller 11 during the crushing process by the air flow, and at the same time promotes the plastic sections inside the machine frame 10 to maintain a concentrated state in the middle area, ensuring good crushing effect, maintaining the good operating state of the equipment, improving work efficiency, extending service life, and reducing maintenance requirements.

[0042] As Figure 10 and Figure 11As shown in the figure, the cleaning mechanism 6 further includes drive gears two 64 respectively arranged at the shaft ends of the electric crushing rollers 11 on both sides. Between the two sides of the machine frame 10, cleaning rollers 65 adapted to the layout of the electric crushing rollers 11 are symmetrically arranged. The cleaning rollers 65 are respectively located below the electric crushing rollers 11 on the same side, and driven gears 66 meshing with the drive gears two 64 on the same side are arranged at the shaft ends of the cleaning rollers 65. With the driving rotation of the electric crushing rollers 11, the connected drive gears two 64 rotate accordingly and mesh with the corresponding driven gears 66, thereby driving the cleaning rollers 65 to rotate. The surface of the cleaning rollers 65 has tough cluster-shaped bristles, which can closely fit the surface of the electric crushing rollers 11, effectively removing the debris stuck between them, ensuring the continuous and efficient operation of the equipment and maintaining the overall performance.

[0043] The above are only examples of the present invention and are not intended to limit the present invention. All equivalent replacements made within the principles of the present invention shall be included within the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art of those skilled in the art.
