Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing, and specifically to a flash recycling device for plastic processing. Background Art

[0002] Plastic processing refers to the process of processing plastic raw materials (usually plastic pellets or resins) into various forms and applications through a series of physical, chemical, or mechanical means. During plastic processing, flash refers to the excess plastic material formed when the plastic product is molded due to incomplete closure of the mold or excessive injection of plastic into the edges of the mold. These flashes are usually thin and fine plastic edges that do not conform to the standard shape of the product and often require subsequent removal or trimming.

[0003] The recycling of flash generated during plastic processing is an important link, especially helpful for improving production efficiency, reducing material waste, and lowering costs. Flash recycling can not only minimize resource waste but also reduce environmental impact through a reasonable treatment process.

[0004] In the prior art, after removing the flash during plastic processing, the staff will collect the flash that has fallen to the ground and place it inside the collection box on one side of the plastic processing device. After a certain amount, it is transported to the flash recycling device area, and the flash inside the collection box is uniformly introduced into the recycling device for crushing. However, when the staff collects the flash, the dust on the ground will be collected into the collection box together with the flash, and the outer wall of the flash will be contaminated with dust, which affects the quality of the plastic during recycling. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a flash recycling device for plastic processing to solve the technical problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A flash recycling device for plastic processing, including a device main body, a recycling box, and a feeding pipe. The recycling box is installed on the inner wall of the device main body, and the feeding pipe is installed at the upper end of the recycling box. The upper end of the feeding pipe is provided with a feeding port; A plurality of groups of first crushing disks are movably installed at the bottom end of the feeding pipe. The recycling box internally is provided with a first collection bin, a screening bin, and a second collection bin. First air outlet plates are symmetrically installed on the inner wall of the screening bin. A second air outlet plate is installed on one side of the upper end inner wall of the screening bin, and a dust suction plate is installed on the other side of the upper end inner wall of the screening bin, and the second air outlet plate corresponds to the dust suction plate. A collection box is movably installed at the bottom end of the second collection bin; Inside the device body, a first air box and a second air box are installed. At one end of the first air box, multiple groups of first air outlet pipes are installed. One ends of two groups of the first air outlet pipes are respectively connected to two first air outlet plates. At one end of the second air box, a second air outlet pipe is installed, and one end of the second air outlet pipe is connected to the second air outlet plate; At the other end of the second air box, a second air inlet pipe is installed.

At the upper end of the dust collection box, a dust suction pipe is installed, and one end of the dust suction pipe is connected to the dust suction plate.

[0007] By adopting the above technical solution, the problem of dust adhering to the outer wall of the flash is solved. Multiple groups of first crushing disks initially perform crushing operations on the flash, reducing the adhesion degree of the dust adhering to the outer wall of the flash. If some of the dust adhering to the outer wall of the flash agglomerates into mud blocks, the mud blocks will be crushed. Then, the initially crushed flash and dust fall into the first collection bin and then into the screening bin. The two first air outlet plates blow air from the bottom end of the screening bin, thereby blowing some of the initially crushed flash and the dust in the flash upward. Then, the second air outlet plate blows out air, causing some of the initially crushed flash and dust to float towards the dust suction plate. Then, the dust suction plate absorbs the dust and some of the initially crushed flash. The dust enters the dust suction pipe through the dust suction plate, and then the dust enters the dust collection box through the dust suction pipe, thereby cleaning the dust mixed in the flash and improving the quality of the plastic after flash recycling.

[0048] Please refer to Figure 19 - Figure 20 , one end of the dust suction plate 51 is provided with a filter screen. A reciprocating thread groove is formed on the outer wall of the third movable shaft 52. A movable block 53 is movably installed on the outer wall of the third movable shaft 52, and the inner wall of the movable block 53 is movably connected to the outer wall of the third movable shaft 52. A scraper 54 is installed on the outer wall of the movable block 53, and the scraper 54 is movably connected to the outer wall of the filter screen. The third movable shaft 52 rotates. The outer wall of the third movable shaft 52 is threadedly connected to the inner wall of the movable block 53, and the thread groove on the outer wall of the third movable shaft 52 is a reciprocating thread groove. Therefore, the movable block 53 makes a reciprocating displacement, thereby driving the scraper 54 to make a reciprocating displacement.

[0049] The working principle of the present invention is as follows: When the staff uses the device to recycle the flash generated during plastic processing, the staff starts the first drive motor 6 and the second drive motor 13 through the control screen 2. The first drive motor 6 drives a set of first drive shafts 7 to rotate, thereby driving a set of first drive gears 9 to rotate. Multiple sets of first drive gears 9 are meshed and connected. When multiple sets of first drive gears 9 rotate, multiple sets of first drive shafts 7 rotate, and the rotation directions of adjacent first drive shafts 7 are opposite, thereby driving multiple sets of first crushing disks 8 to rotate. The second drive motor 13 drives a set of second drive shafts 14 to rotate, thereby driving the second drive gear 16 to rotate. The second drive gear 16 is meshed and connected with the transmission gear 18. When the transmission gear 18 rotates, it drives the first transmission shaft 17 to rotate. The first rotating shaft 17 is connected to another set of second drive shafts 14 through a synchronous belt. Another set of second drive shafts 14 rotates, and the rotation directions of the two sets of second drive shafts 14 are opposite, thereby driving two sets of second crushing disks 15 to rotate; When another set of second drive shafts 14 rotates, there is a synchronous belt connection between another set of second drive shafts 14 and the limit shaft 19. The limit shaft 19 rotates. The outer wall of the limit shaft 19 is threadedly connected to the inner wall of the movable ring 20, and the thread groove on the outer wall of the limit shaft 19 is a reciprocating thread groove. Therefore, the movable ring 20 reciprocates. The movable ring 20 first moves towards the third speed change gearbox 57, thereby driving the toothed plate 21 and the convex plate 22 to move, and further driving the telescopic column 23 to move; When the movable ring 20 moves, it first drives the telescopic column 23 to move out of the contraction cylinder 31. The outer wall of the telescopic column 23 is threadedly connected to the inner wall of the contraction cylinder 31. The contraction cylinder 31 rotates. One end of the contraction cylinder 31 is connected to the input end of the second speed change gearbox 30, thereby conducting the kinetic energy into the second speed change gearbox 30. After the second speed change gearbox 30 increases the rotational speed, it drives the second output shaft 32 to rotate. The second output shaft 32 is connected to a set of second movable shafts 34 through a synchronous belt. A set of second movable shafts 34 rotates, and multiple sets of second movable shafts 34 are respectively connected through synchronous belts. Multiple sets of second movable shafts 34 rotate. The outer walls of multiple sets of second movable shafts 34 are threadedly connected to the inner wall of the second partition plate 33. Therefore, the second partition plate 33 moves, and the second partition plate 33 closes the connection end between the screening bin 11 and the second collection bin 12; After the telescopic column 23 is separated from the contraction cylinder 31, the movable ring 20 continues to displace, thereby driving the toothed plate 21 to continuously displace. The toothed plate 21 is meshed and connected with the input gear 26, and the input gear 26 rotates, thereby driving the input shaft 25 to rotate. The input shaft 25 conducts kinetic energy into the first variable-speed gearbox 24. After the first variable-speed gearbox 24 increases the rotational speed, it drives the first output shaft 27 to rotate. The first output shaft 27 is connected to a group of first movable shafts 28 through a synchronous belt. A group of first movable shafts 28 rotate, and multiple groups of first movable shafts 28 are respectively connected through synchronous belts. Multiple groups of first movable shafts 28 rotate, and the outer walls of multiple groups of first movable shafts 28 are all threadedly connected to the inner wall of the first partition plate 29. The first partition plate 29 displaces, and the first partition plate 29 moves into the device main body 1, making the first collection bin 10 communicate with the screening bin 11; When the limit shaft 19 rotates, the limit shaft 19 conducts kinetic energy into the third variable-speed gearbox 57. After the third variable-speed gearbox 57 increases the rotational speed, it drives the third output shaft 58 to rotate. The third output shaft 58 is connected to the second transmission shaft 35 through a synchronous belt. The second transmission shaft 35 rotates, and one end of the second transmission shaft 35 is connected to the first linkage shaft 37 through a synchronous belt. The first linkage shaft 37 rotates, thereby driving the fan inside the first air box 36 to rotate, generating an air flow inside the first air box 36. The air flow enters the first air box 36 through the first air inlet pipe 41. The air flow enters multiple groups of first air outlet pipes 38 respectively, and multiple groups of first air outlet pipes 38 discharge the air flow through two groups of first air outlet plates 39 and the air outlet seat 40; When the air flow enters the first air box 36 through the first air inlet pipe 41, it drives the wind wheel 43 to rotate, thereby driving the third transmission shaft 42 to rotate. The third linkage shaft 42 is connected to the second linkage shaft 45 through a synchronous belt. The second linkage shaft 45 rotates, thereby driving the fan inside the second air box 44 to rotate, generating an air flow inside the second air box 44. The air flow enters the second air box 44 through the second air inlet pipe 48, generating a negative pressure inside the dust collection box 49. Therefore, the dust suction plate 51 generates suction, and the air flow is discharged through the second air outlet pipe 46. Then the air flow is discharged through the second air outlet plate 47, and the wind force of the second air outlet plate 47 is less than the wind force of the two groups of first air outlet plates 39; When the second linkage shaft 45 rotates, the other end of the second linkage shaft 45 is connected to the third movable shaft 52 through a synchronous belt. The third movable shaft 52 rotates, and the outer wall of the third movable shaft 52 is threadedly connected to the inner wall of the movable block 53. And the thread groove on the outer wall of the third movable shaft 52 is a reciprocating thread groove. Therefore, the movable block 53 makes a reciprocating displacement, and further drives the scraper 54 to make a reciprocating displacement; After the staff starts the first drive motor 6 and the second drive motor 13, the staff introduces the flash from the feed inlet 5 into the interior of the feed pipe 4, and the air outlet seat 40 blows the air flow towards the feed pipe 4, thereby assisting the flash in displacing inside the feed pipe 4, avoiding blockage of the flash inside the feed pipe 4. When the flash moves to the area of multiple groups of first crushing discs 8, the multiple groups of first crushing discs 8 initially crush the flash. After the flash is initially crushed, it enters the interior of the first collection bin 10. When the first collection bin 10 is connected to the screening bin 11, the screening bin 11 and the second collection bin 12 are in a closed state. The initially crushed flash falls into the interior of the screening bin 11. Two groups of first air outlet plates 39 blow the air flow out from the bottom end of the screening bin 11, thereby blowing part of the initially crushed flash and the dust in the flash upwards. Then, the air flow is blown out from the end of the second air outlet plate 47, causing part of the initially crushed flash and the dust to float towards the dust suction plate 51. Then, the dust suction plate 51 absorbs the dust and part of the initially crushed flash. The dust enters the interior of the dust suction pipe 50 through the dust suction plate 51, and then the dust enters the interior of the dust collection box 49 through the dust suction pipe 20. And the filter screen at the end of the dust suction plate 51 blocks part of the crushed flash. Then, the scraper 54 reciprocates to clean the part of the crushed flash adhering to the outer wall of the filter screen, avoiding the part of the crushed flash adhering to the outer wall of the filter screen from affecting the dust absorption effect; After the first partition plate 29 closes the connection end between the first collection bin 10 and the screening bin 11, the flash initially crushed by multiple groups of first crushing discs 8 falls onto the upper end of the first partition plate 29. Then, the second partition plate 33 moves into the device main body 1, and the connection end between the screening bin 11 and the second collection bin 12 is opened. The flash initially crushed and screened inside the screening bin 11 falls into the interior of the second collection bin 12. Two groups of guide plates 56 guide the initially crushed flash between two groups of second crushing discs 15, and the two groups of second crushing discs 15 crush the flash a second time, thereby improving the crushing effect of the flash. The flash after secondary crushing falls into the collection box 55.
