Description

Technical Field

[0001] The invention belongs to the field of plastic processing, in particular to a polymer plastic film crushing and granulating device. Background Art

[0002] Polymer plastic film is a film made of polymer materials, such as polytetrafluoroethylene film, polyvinylidene fluoride film, etc. If the polymer plastic film is not recycled after use, it may cause pollution to the environment. Crushing and granulation can convert waste polymer plastic film into reusable particles to achieve resource recycling and reuse.

[0003] The utility model patent with announcement number CN216831731U discloses a plastic crushing and granulating device, including a screw extrusion granulator, which includes a sleeve, a screw is arranged in the sleeve, one end of the sleeve is connected to the feeding bin, and the other end of the sleeve is connected to the machine head, a cutter is arranged at the outlet of the machine head, a rotating rod is arranged horizontally below the feeding port in the feeding bin, a crushing knife is arranged on the rotating rod, one end of the rotating rod is connected to the output shaft of the driving motor through a rotating shaft, a drying device is arranged in the feeding bin, and the discharge port at the bottom of the feeding bin is connected to the feed port at the top of the sleeve. The device described in the utility model can realize the crushing function and the extrusion granulation function at the same time, which facilitates the processing process, improves the processing efficiency, and reduces the labor burden of workers. Moreover, while crushing the plastic, it can also realize the drying of the plastic, ensuring the smooth progress of the subsequent processing process.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] During the extrusion process of the screw, some extrusion dead corners will appear, resulting in part of the raw materials remaining in the sleeve. The remaining raw materials may block or affect the flow channel in the sleeve, thereby reducing the extrusion efficiency. In addition, it is difficult to ensure that the raw materials are completely crushed during the shredding process. Therefore, if the raw materials are not completely crushed, there will be larger particles or lumps. If the raw materials are too large, the internal part may not reach the required plasticizing temperature, thereby maintaining hardness and being difficult to extrude.

[0043] A baffle 47 is rotatably provided on one side of the material receiving box 46, a motor 11 48 is fixedly connected to one side of the material receiving box 46, and an output end of the motor 11 48 is fixedly connected to one side of the baffle 47;

[0044] Specifically, polymer plastic film is a film made of polymer materials, such as polytetrafluoroethylene film, polyvinylidene fluoride film, etc. After use, if the polymer plastic film is not recycled, it may cause pollution to the environment. Grinding and granulation can convert the waste polymer plastic film into particles that can be used again, so as to realize the recycling and reuse of resources. When the existing grinding and granulation equipment is used, the raw materials are first chopped, and the chopped raw materials enter the sleeve, and then melted under high temperature and extrusion of the screw. The molten raw materials are transported to the head through the screw, extruded outward after cooling, and then cut by the cutter at the outlet. However, due to the partial extrusion dead angle in the process of extruding the raw materials by the screw, part of the raw materials will remain in the sleeve. The residual raw materials may block or affect the flow channel in the sleeve, thereby reducing the extrusion efficiency. In addition, it is difficult to ensure that the raw materials are completely crushed during the shredding process. Therefore, if the raw materials are not completely crushed, there will be larger particles or lumps. If the raw materials are too large, the required plasticizing temperature may not be reached inside, thereby maintaining hardness and being difficult to extrude. In addition, when the raw materials remain inside the sleeve, this part of the raw materials cannot be effectively utilized, thereby reducing the overall utilization rate of the raw materials.

[0045] Therefore, when the present embodiment is in use, the motor 14 is turned on to drive the rotating shaft 16 to rotate, so that the crushing blade 17 rotates, and then the polymer plastic film raw material is added to the crushing bucket 7, and the crushing blade 17 can be used to cut and crush the raw material. The cut and crushed raw material enters the extrusion barrel 11 through the feeding pipe 38, and then the inside of the extrusion barrel 11 is heated under the action of the electric heating coil 39 to make the raw material molten. Then, the spiral blade 37 is rotated under the action of the motor 9 36 to move the raw material downward and pass through the extrusion hole. 34 is extruded, and then the reciprocating screw rod 30 is rotated under the action of the motor 8 29, so that the slider 32 moves back and forth left and right, so that the blade 33 pelletizes the extruded raw material, and the particles fall into the collection box 12 for collection. When the blade 33 moves to the scraper 45, the bottom of the scraper 45 is attached to the upper and lower surfaces of the blade 33 under the action of the spring damper 43, so that the raw material remaining due to the cutting of the blade 33 can be scraped off, and the scraped raw material falls to the unloading plate 54, and falls into the receiving box 46 under the action of gravity for collection;

[0046] When the extrusion barrel 11 no longer extrude raw materials, it means that most of the raw materials have been extruded. At this time, there is still residual raw material on the inner wall of the extrusion barrel 11. The two-way threaded rod 4 can be driven to rotate by starting the motor 15 so that the adjustment blocks 40 on both sides slide and move away from each other at the same time, so that the two extrusion barrels 11 can be separated. In addition, the extrusion barrel 11 is moved above the blanking plate 54, and then the motor 10 41 is started to drive the extrusion barrel 11 to rotate 90 degrees to make the extrusion barrel 11 straight. When the extrusion barrels 11 move away from each other, the raw materials attached to the inner wall will be cooled, so the viscosity will be reduced, and the extrusion barrels 11 can be straightened. The raw materials attached to the inner cavity of the cylinder 11 fall onto the unloading plate 54 under the action of gravity, and then fall into the receiving box 46. In addition, the motor 6 22 can be started to drive the threaded rod 21 to rotate, so that the lifting plate 19 rises, and the scraper 23 rises and fits the inner wall of the extrusion cylinder 11. Then, the motor 5 20 is started to drive the scraper 23 to rotate, so that the scraper 23 can scrape the raw materials on the inner wall of the extrusion cylinder 11, further promoting the falling of the raw materials and increasing the collection amount. At the same time, the through hole of the fixed disk 24 is aligned with the extrusion hole 34, and then the motor 7 25 is started to drive the threaded rod 3 26 to rotate. The mounting plate 27 is moved, and the dredging column 28 passes through the through hole of the fixing plate 24 and the extrusion hole 34, so that the raw material attached to the wall of the extrusion hole 34 can be pushed down and also dropped into the inside of the material receiving box 46. When the raw materials on the inner wall of the extrusion cylinder 11 and the wall of the extrusion hole 34 are scraped off, the two extrusion cylinders 11 are driven back to the initial position, and then the threaded rod 10 is rotated under the action of the motor 29, so that the material receiving box 46 rises until the material receiving box 46 is higher than the crushing bucket 7, and then the threaded rod 4 50 is rotated under the action of the motor 12 52, so that one end of the material receiving box 46 is Above the crushing bucket 7, the motor 13 53 is then used to drive the material receiving box 46 to rotate and tilt it, and then the baffle 47 is rotated under the action of the motor 11 48 to open one end of the material receiving box 46, so that the raw materials inside the material receiving box 46 can be poured into the crushing bucket 7, and then crushed again, so that large pieces of raw materials can be crushed again, and enter the extrusion barrel 11 again for melting, and then extrusion granulation is carried out; and when the surface of the blade 33 and the inner wall of the extrusion barrel 11 are scraped, the structures used for the two scraping operations are staggered and will not interfere with each other;

[0047] Therefore, by utilizing the scraping collection mechanism, the raw materials adhered to the surface of the blade 33 can be scraped off during the pelletizing process, thereby avoiding the situation where the size of the cut particles is uneven due to the raw materials adhered to the blade. Moreover, when the extruder 11 no longer extrude the raw materials, the raw materials adhered to the inner cavity wall of the extruder 11 and the wall of the extrusion hole 34 can be scraped off, thereby avoiding the situation where the raw materials remain on the inner wall of the extruder 11 and the wall of the extrusion hole 34, causing the raw materials to block the internal channel of the extruder 11 and the extrusion hole 34, which helps to maintain the extrusion efficiency. In addition, the scraped raw materials can be collected and re-conveyed to the crushing bucket 7 for secondary crushing and granulation, thereby avoiding the situation where part of the raw materials cannot be effectively utilized due to the raw materials remaining in the sleeve, thereby reducing the overall utilization rate of the raw materials.

[0048] In this embodiment, Figure 5 As shown, a cover body 6 is rotatably provided on one side of the upper end of the crushing bucket 7, a motor 3 13 is fixedly connected to one side of the upper end of the crushing bucket 7, and an output end of the motor 3 13 is fixedly connected to one end of the cover body 6;

[0049] Specifically, when the crushing bucket 7 is crushing, the cover body 6 can be rotated under the action of the motor 3 13, so that the cover body 6 covers the upper end of the crushing bucket 7, thereby avoiding the splashing of raw materials during the crushing process, thereby protecting the safety of operators, avoiding injuries from splashing materials, reducing pollution to the working environment, and ensuring the cleanliness of the working area.

[0050] Working principle: Turn on the motor 4 14 to drive the rotating shaft 16 to rotate, so that the crushing blade 17 rotates, and then the polymer plastic film raw material is added to the crushing bucket 7, and the crushing blade 17 can be used to cut and crush the raw material. When the crushing work is carried out inside the crushing bucket 7, the cover body 6 can be rotated under the action of the motor 3 13, so that the cover body 6 covers the upper end of the crushing bucket 7, which can avoid the splashing of the raw material during the crushing process, thereby protecting the safety of the operator, avoiding injury by the splashing material, and reducing the pollution to the working environment, ensuring the cleanliness of the working area; the cut and crushed raw material enters the extruder 11 through the feed pipe 38, and then under the action of the electric heating coil 39 , so that the temperature inside the extrusion barrel 11 is increased, so that the raw material is in a molten state, and then the spiral blade 37 is rotated under the action of the motor 9 36, so that the raw material moves downward and is extruded through the extrusion hole 34, and then the reciprocating screw rod 30 is rotated under the action of the motor 8 29, so that the slider 32 reciprocates left and right, so that the blade 33 pelletizes the extruded raw material, and the particles fall into the collection box 12 for collection. When the blade 33 moves to the scraper 45, the bottom of the scraper 45 is attached to the upper and lower surfaces of the blade 33 under the action of the spring damper 43, so that the raw material remaining due to the cutting of the blade 33 can be scraped off, and the scraped raw material falls to the unloading plate 54, and falls into the receiving box 46 under the action of gravity for collection;When the extrusion barrel 11 no longer extrude raw materials, it means that most of the raw materials have been extruded. At this time, there is still residual raw material on the inner wall of the extrusion barrel 11. The two-way threaded rod 4 can be driven to rotate by starting the motor 15 so that the adjustment blocks 40 on both sides slide and move away from each other at the same time, so that the two extrusion barrels 11 can be separated, and the extrusion barrel 11 is moved above the discharge plate 54, and then the motor 10 41 is started to drive the extrusion barrel 11 to rotate 90 degrees to make the extrusion barrel 11 straight. When the extrusion barrels 11 move away from each other, the raw material attached to the inner wall thereof will be cooled down, so the viscosity will be reduced, and the raw material attached to the inner cavity of the extrusion barrel 11 can fall onto the discharge plate 54 and fall into the receiving box 46 under the action of gravity. In addition, the motor 6 22 can be started to drive the extrusion barrel 11 to rotate 90 degrees to make the extrusion barrel 11 straight. The movable threaded rod 21 rotates, so that the lifting plate 19 rises, so that the scraper 23 rises and fits the inner wall of the extrusion tube 11, and then the motor 5 20 is started to drive the scraper 23 to rotate, so that the scraper 23 can scrape the raw material on the inner wall of the extrusion tube 11, further promoting the falling of the raw material and increasing the collection amount. At the same time, the through hole of the fixed disk 24 is aligned with the extrusion hole 34, and then the motor 7 25 is started to drive the threaded rod 3 26 to rotate, so that the mounting disk 27 moves, so that the dredging column 28 passes through the through hole of the fixed disk 24 and passes through the extrusion hole 34, so that the raw material attached to the hole wall of the extrusion hole 34 can be pushed down and also falls into the inside of the material receiving box 46. When the raw materials on the inner cavity wall of the extrusion tube 11 and the hole wall of the extrusion hole 34 are scraped off, the two extrusion tubes are driven to move. 11 returns to the initial position, and then the threaded rod 10 is rotated under the action of the motor 2 9, so that the material receiving box 46 rises until the material receiving box 46 is higher than the crushing bucket 7, and then the threaded rod 4 50 is rotated under the action of the motor 12 52, so that one end of the material receiving box 46 is above the crushing bucket 7, and then the motor 13 53 is used to drive the material receiving box 46 to rotate and tilt it, and then the baffle 47 is rotated under the action of the motor 11 48 to open one end of the material receiving box 46, so that the raw materials in the material receiving box 46 can be poured into the crushing bucket 7, and then crushed again, so that large pieces of raw materials can be crushed again and enter the extrusion barrel 11 again for melting, and then extrusion granulation work is carried out; thereby, the scraping collection mechanism can be used to During the pelletizing process of the blade 33, the raw materials attached to the surface are scraped off, thereby avoiding the situation that the size of the cut particles is uneven due to the raw materials attached to the blade. Moreover, when the extruder 11 no longer extrude the raw materials, the raw materials attached to the inner wall of the extruder 11 and the wall of the extrusion hole 34 are scraped off, thereby avoiding the situation that the raw materials remain on the inner wall of the extruder 11 and the wall of the extrusion hole 34, thereby avoiding the situation that the raw materials block the internal channel of the extruder 11 and the extrusion hole 34, which helps to maintain the extrusion efficiency. Moreover, the scraped raw materials can be collected and re-transported to the crushing bucket 7 for secondary crushing and granulation, thereby avoiding the situation that part of the raw materials cannot be effectively utilized due to the raw materials remaining in the sleeve, thereby reducing the overall utilization rate of the raw materials. ;
