Abstract
Description
Technical Field
[0001] This utility model relates to the field of compression molding machine technology, and more specifically, it relates to a plastic compression molding machine for plastic granulation production. Background Technology
[0002] In the existing technology field, plastic compression molding machines used for plastic granulation production face a series of operational convenience issues during actual use, resulting in low production efficiency. Specifically, existing compression molding machines cannot easily complete the compression molding process for plastic granulation, requiring operators to perform tedious adjustments and frequent maintenance, which increases production costs and time costs.
[0003] In existing plastic granulation processes, the fixing process between the filter plate and the feed box cannot be quickly disassembled during use. This technical defect leads to many challenges when producing plastic granules of different specifications. When it is necessary to replace the filter plate with a different pore size, the operator usually needs to stop the machine, cool the equipment, and then use specific tools to disassemble it. The whole process is time-consuming and cumbersome. Especially in high-temperature environments, the connecting parts between the filter plate and the feed box are prone to deformation or adhesion due to thermal expansion and contraction.
[0004] Similarly, existing plastic pelleting processes cannot quickly complete the fixing process between the filter plate and the feed box. After replacing the filter plate, it is also difficult to reinstall it onto the feed box. Traditional fixing methods usually rely on multiple bolts or clips, which require precise alignment and even force application. Otherwise, improper installation of the filter plate can easily lead to the product quality being affected. Utility Model Content

[0033] Please see Figures 1-8 A plastic compression molding machine for plastic granulation production includes a feeding box 1, on which a conveying assembly is provided. The conveying assembly includes a fixed frame 2 and a feeding box 3. The fixed frame 2 is located at one end of the feeding box 1, and the feeding box 3 is located on the fixed frame 2. A second motor 4 is installed on the fixed frame 2. The output end of the second motor 4 is connected to a drive assembly 5, and the output end of the drive assembly 5 is connected to a tilting plate 6. The tilting plate 6 is rotatably connected in the feeding box 3. A splitting assembly is provided on the feeding box 3. The splitting assembly includes a filter plate 7 and a placement plate 8. The filter plate 7 is slidably connected to the feeding box 3, and the placement plate 8 is connected to the filter plate 7. A placement sleeve 9 is detachably installed on the placement plate 8.
[0034] One end of the feed box 3 is connected to an inclined bucket 10, and a feed hopper 11 is installed on the conveying box 1. The inclined bucket 10 is aligned with the feed box 3. A first motor 12 is installed on the conveying box 1, and a conveying rod 13 is connected to the output end of the first motor 12.
[0035] The conveying rod 13 is fitted with a spiral blade 14, and a collecting cylinder 15 is installed on one side of the conveying box 1. An extraction pipe 16 is connected between the collecting cylinder 15 and the conveying box, and a pump body is connected to the extraction pipe 16.
[0036] A rotating sleeve 17 is rotatably connected to the placement sleeve 9, a rotating block 18 is installed on the rotating sleeve 17, and a rotating rod 19 is connected to the rotating block 18.
[0037] A placement block 20 is installed on the placement sleeve 9. The placement block 20 is rotatably connected to the rotating rod 19. A second spring 21 is sleeved on the rotating rod 19. The two ends of the second spring 21 are connected to the rotating block 18 and the placement block 20.
[0038] In this embodiment, material is injected into the feed box 3 through the feed inlet 27. The second motor 4 is activated, driving the drive assembly 5 to rotate the tilting plate 6, thus tilting the material. The tilted material falls onto the filter plate 7 for filtration, while material with a pore size larger than the holes in the filter plate 7 is retained. The filtered material then falls into the conveying box 1 through the feed hopper 11. The first motor 12 is activated, rotating the conveying rod 13, which uses the spiral blades 14 to complete the filtration process. For material conveying, the conveyed material is discharged and drawn into the collection cylinder 15 by the extraction pipe 16. When it is necessary to filter granular materials of different sizes, the filter plate 7 needs to be replaced. At this time, the rotating sleeve 17 is rotated along the placement sleeve 9. During the rotation, the rotating block 18 drives the rotating rod 19 to rotate along the placement block 20. During the rotation, the second spring 21 between the placement block 20 and the rotating block 18 is compressed. When the empty slot 25 is aligned with the locking block 23, the abutment of the locking block 23 is released.
[0039] Please see Figure 5-8 As an embodiment of a plastic compression molding machine for plastic granulation production with a fixed component: a fixed component is provided on the placement sleeve 9. The fixed component includes a placement rod 22 and a locking block 23. The placement rod 22 is installed on the feed box 3 and is detachably connected to the placement sleeve 9.

[0041] The placement rod 22 has a locking groove 26, which is compatible with the locking block 23. The feed box 3 has a feed inlet 27.
[0042] More specifically, after releasing the locking block 23, the placement sleeve 9 is slid out along the placement rod 22. When it is removed, under the elastic potential energy of the first spring 24, one end of the locking block 23 is moved out of the locking groove 26, releasing the fixation of the placement rod 22. At this time, the filter plate 7 and the placement plate 8 can be slid out along the placement rod 22 to replace the filter plate 7. After replacement, the above operation is repeated in reverse to fix the filter plate 7, thereby completing the filtration of materials of different particle sizes.
[0043] In summary, during the use or operation of the entire equipment: material is injected into the feed box 3 through the feed inlet 27, and by starting the second motor 4, the drive assembly 5 is activated, thereby driving the rotating plate 6 to rotate, thus completing the rotation of the material. The rotated material falls onto the filter plate 7 for filtration, while material with a pore size larger than the pores on the filter plate 7 is retained. The filtered material falls into the conveying box 1 through the feed hopper 11, and by starting the first motor 12, the conveying rod 13 is rotated, so that the spiral plate 1... 4. The material is conveyed and discharged. The material is then drawn into the collection cylinder 15 using the extraction pipe 16. When it is necessary to filter granular materials of different sizes, the filter plate 7 needs to be replaced. At this time, the rotating sleeve 17 is rotated along the placement sleeve 9. During the rotation, the rotating block 18 drives the rotating rod 19 to rotate along the placement block 20. During the rotation, the second spring 21 between the placement block 20 and the rotating block 18 is compressed. When the empty slot 25 is aligned with the locking block 23, the contact with the locking block 23 is released.
[0044] After releasing the locking block 23, the placement sleeve 9 is slid out along the placement rod 22. When it is removed, under the elastic potential energy of the first spring 24, one end of the locking block 23 is moved out of the locking groove 26, releasing the fixation of the placement rod 22. At this time, the filter plate 7 and the placement plate 8 can be slid out along the placement rod 22 to replace the filter plate 7. After replacement, the above operation is repeated in reverse to fix the filter plate 7, thereby completing the filtration of materials of different particle sizes.
[0045] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
