[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a defoaming component to defoam the molten plastic liquid. A small motor drives the eccentric wheel to rotate. The rotation of the eccentric wheel can intermittently push the sliding ring. When the eccentric wheel pushes the sliding ring downward, the sliding ring slides downward on the outer side of the mounting column.

When the sliding ring loses its driving force as the eccentric wheel rotates, the first spring and the second spring drive the sliding ring to slide upward by relying on the elastic restoring force. As the eccentric wheel rotates, the sliding sleeve can vibrate up and down reciprocatingly. The sliding sleeve drives the vibration plate to vibrate inside the molten barrel, thereby achieving defoaming of the plastic melt in the molten barrel.

[0017] 2. The present invention cools the extruded plastic strips through a spray head installed on the top of the inner wall of the collection cabinet, and can remove dust particles and harmful gases in the collection cabinet. The sprayed liquid mist reacts with the harmful gases in the collection cabinet to remove the harmful gases. The harmful gases are treated by the water mist formed by the liquid medicine and finally escape outward through the filter cartridge. The filter cartridge further purifies the gas in the collection cabinet to prevent the harmful gases from affecting the surrounding environment.

[0018] 3. The present invention facilitates the installation and fixation of the filter cartridge by installing a fixing component. The position of the T-shaped block is moved by pulling the pull rod and utilizing the elastic restoring force of the third spring so that the T-shaped block and the card slot on the filter cartridge match each other, thereby achieving the installation and fixation of the filter cartridge and improving the convenience of the operator in replacing the filter cartridge.

[0019] 4. The present invention achieves insulation of the plastic melt by providing an insulation tube and insulation cotton.

A sliding ring 10 is slidably installed on the outer side of the mounting column 8, and the top of the sliding ring 10 is intermittently in contact with the eccentric wheel 9. The bottom of the sliding ring 10 is connected to a first spring 11, and the first spring 11 is located on the outer side of the mounting column 8. The bottom end of the first spring 11 is connected to a sliding sleeve 12. A limiting groove 16 is symmetrically provided on the outer surface of the mounting column 8. A limiting clip 17 is symmetrically installed on the inner side of the sliding sleeve 12, and the limiting clip 17 is slidably connected to the limiting groove 16.

A fixing sleeve 15 is fixedly installed on the outer side of the mounting column 8, and the top of the fixing sleeve 15 is connected to the second spring 14.

[0026] Further, after the raw material of the heat-resistant plastic particles is put into the melting tube 5, a plastic melt is formed under the heating effect of the melting tube 5. There may be bubbles in the plastic melt inside the melting tube 5. The small motor 7 drives the eccentric wheel 9 to rotate. The rotation of the eccentric wheel 9 can intermittently push the sliding ring 10. When the eccentric wheel 9 pushes the sliding ring 10 downward, the sliding ring 10 slides downward on the outer side of the mounting column 8. The first spring 11 and the second spring 14 are squeezed and compressed, so that the sliding sleeve 12 slides downward under the limiting effect of the limiting groove 16 and the limiting card strip 17. The sliding ring 1 When the eccentric wheel 9 loses its driving force as it rotates, the first spring 11 and the second spring 14 drive the sliding ring 10 to slide upwards by means of elastic restoring force. As the eccentric wheel 9 rotates, the sliding sleeve 12 can vibrate up and down reciprocatingly. The sliding sleeve 12 drives the vibration plate 13 to vibrate inside the melting tube 5, thereby achieving defoaming treatment of the plastic melt in the melting tube 5. The defoaming treatment of the plastic melt in the melting tube 5 by the defoaming component avoids the influence of bubbles on the extruded plastic particles, thereby improving the quality and performance of the plastic particle products produced by the plastic particle granulation equipment.

[0027] See also Figure 1 and Figure 3 An embodiment of the present invention is: a heat-resistant plastic particle granulation equipment for cable production, wherein a driving motor 18 is installed on the top of the support frame 1, and the driving motor 18 is located on the left side of the spiral extrusion box 2, and the output end of the driving motor 18 passes through the inner wall of one side of the spiral extrusion box 2 and is connected to a rotating shaft 19, and the rotating shaft 19 passes through the outer wall of the other side of the spiral extrusion box 2, and a spiral feeding piece 20 is installed on the outer surface of the rotating shaft 19, and the spiral feeding piece 20 is located inside the spiral extrusion box 2.

[0029] Furthermore, when the device is used, the raw materials for producing heat-resistant plastic particles are firstly fed from the feed hopper 6 into the interior of the melting tube 5, and the heating plate 23 inside the melting tube 5 heats and liquefies the raw materials inside, and after the defoaming component defoams the molten liquid, the control valve 4 is opened to allow the molten liquid to pass through the filter residue net 24 and enter the interior of the spiral extrusion box 2 along the feed pipe 3, and the large particles in the molten liquid that have not been liquefied will stay on the filter residue net 24; The driving motor 18 drives the rotating shaft 19 to rotate. After the molten plastic liquid enters the spiral extrusion box 2, the rotation of the rotating shaft 19 drives the spiral feeding piece 20 to rotate together, so that the spiral feeding piece 20 transports the molten plastic liquid to the discharge hole 21. As the spiral feeding piece 20 transports the plastic melt, the plastic in the discharge hole 21 is squeezed, thereby realizing extrusion discharge. The outer wall of the spiral extrusion box 2 is installed with the rotating shaft 19 through a sealing shaft ring. The cutting knife 22 installed on the outer surface of the rotating shaft 19 rotates with the rotating shaft 19. The rotating cutting knife 22 cuts the extruded plastic particle strips, so that the plastic particle strips are cut into smaller particles.

[0030] See also Figure 1 An embodiment of the present invention is a heat-resistant plastic particle granulation equipment for cable production, wherein an opening is provided at the top of the melting cylinder 5, and a first filter screen 26 is embedded and installed at the top opening of the melting cylinder 5, an air collecting hood 27 is installed at the top of the melting cylinder 5, and the air collecting hood 27 is located above the first filter screen 26, a collecting cabinet 25 is installed on the right side surface of the spiral extrusion box 2 and the support frame 1, a ventilation pipe 28 is connected to one side of the ventilation pipe 28, and one end of the ventilation pipe 28 is connected to the left side of the collecting cabinet 25.

[0031] The inner wall of the filter cartridge 38 is symmetrically installed with a separation filter screen 40, and the two groups of separation filter screens 40 of the filter cartridge 38 are internally installed with activated carbon 41. The fixing assembly includes a limit ring 32, a groove 34, a pull rod 35, a T-shaped block 36, a third spring 37 and a groove 39. The inner wall of the installation cartridge 31 is installed with a limit ring 32, and a sealing ring 33 is installed on the right surface of the limit ring 32. The inner wall of the installation cartridge 31 is symmetrically provided with a groove 34. The outer surface of the installation cartridge 31 is movably provided with a pull rod 35, and part of the pull rod 35 is located inside the groove 34.

One end of the third spring 37 is connected to the T-shaped block 36. The outer surface of the filter cartridge 38 is symmetrically provided with a groove 39, and the groove 39 matches the T-shaped block 36. .

[0032] Furthermore, in the process of heating and liquefying the plastic particles, some gas is generated by the melting of the raw materials. The gas enters the gas collecting hood 27 through the first filter screen 26 and enters the interior of the collection cabinet 25 along the ventilation pipe 28. The external delivery pump delivers the cooling liquid water to the spray head 30 installed on the top of the collection cabinet 25 through the liquid inlet pipe 29. The water mist sprayed by the spray head 30 can cool the plastic particle strips extruded from the spiral extrusion box 2. At the same time, the sprayed liquid water mist can also remove dust particles and harmful gases in the collection cabinet 25. The harmful gases are finally processed by the water mist formed by the liquid medicine and escape outward through the filter cartridge 38. The filter cartridge 38 further purifies the gas in the collection cabinet 25 to prevent the harmful gases from affecting the surrounding environment. When the harmful gas treated by the water mist formed by the liquid medicine passes through the filter cartridge 38, the activated carbon 41 in the filter cartridge 38 adsorbs the harmful substances, further purifies the gas in the collection cabinet 25, thereby ensuring that the gas escaping from the collection cabinet 25 is harmless to the environment; The activated carbon 41 in the filter cartridge 38 will become ineffective after being used for a long time, and the filter cartridge 38 needs to be replaced. When disassembling the filter cartridge 38, the staff pulls the pull rod 35 outward to make the protruding block part of the T-shaped block 36 withdraw from the slot 39. At this time, the filter cartridge 38 can be disassembled by pulling it outward; when installing a new filter cartridge 38, the pull rod 35 is pulled outward to drive the T-shaped block 36 to move to the inside of the groove 34, so that the left end of the filter cartridge 38 is squeezed and contacts the sealing ring 33 on the limit ring 32, and the filter cartridge 38 is rotated so that the position of the slot 39 corresponds to the T-shaped block 36. After loosening the pull rod 35, the T-shaped block 36 enters the inside of the slot 39 under the elastic restoring force of the third spring 37, thereby fixing the filter cartridge 38; the fixing assembly is convenient for the staff to install and replace the filter cartridge 38.

[0033] See also Figure 1 An embodiment of the present invention is a heat-resistant plastic particle granulation equipment for cable production, wherein a liquid inlet pipe 29 is connected to the top of a collection cabinet 25, a spray head 30 is symmetrically installed on the inner top wall of the collection cabinet 25, and the spray head 30 is connected to the liquid inlet pipe 29, an outer wall on one side of the collection cabinet 25 and a right side wall of the collection cabinet 25 are connected to a mounting cylinder 31, a filter cylinder 38 is movably installed inside the mounting cylinder 31, a fixing component is arranged inside the mounting cylinder 31, and the fixing component is used to fix the filter cylinder 38, a second filter screen 44 is installed on the inner wall of the collection cabinet 25, a drain pipe 45 is connected to one side of the collection cabinet 25, and the drain pipe 45 is located below the second filter screen 44.

[0034] Furthermore, the cut plastic particles fall onto the second filter screen 44 due to gravity. As time goes by, the liquid medicine on the surface of the plastic particles drips from the second filter screen 44 to the bottom of the collection cabinet 25 under the action of gravity, and is discharged from the interior of the collection cabinet 25 through the drain pipe 45. The plastic particles and the sprayed liquid medicine are separated, which is convenient for the subsequent collection and treatment of the plastic particles. A cabinet door is provided on the front or back of the collection cabinet 25, and the bottom end height of the cabinet door is the same as that of the support frame 1. The cabinet door of the collection cabinet 25 can facilitate the staff to collect the plastic particles.

[0035] See also Figure 1 and Figure 5 An embodiment of the present invention is a heat-resistant plastic particle granulation equipment for cable production, wherein the outer surface of the spiral extrusion box 2 is installed with insulation cotton 43, the outer side of the insulation cotton 43 is installed with an insulation tube 42, and the bottom of the insulation tube 42 is connected to the top of the support frame 1.

[0036] Furthermore, after the molten plastic liquid enters the interior of the spiral extrusion box 2, if the external ambient temperature is low, the low temperature may affect the molten plastic liquid in the spiral extrusion box 2, causing the molten plastic liquid to agglomerate, thereby having a negative impact on the quality of the produced plastic particles. The insulation tube 42 and the insulation cotton 43 outside the spiral extrusion box 2 can insulate the molten plastic liquid in the spiral extrusion box 2, reduce heat loss, and achieve the effect of thermal insulation, thereby avoiding the impact of the low external ambient temperature on the quality of the plastic particles.

[0037] Furthermore, a method for using a heat-resistant plastic particle granulation equipment for cable production is provided, and the method for using the plastic particle granulation equipment is as follows: S1, after the production raw materials are put into the melting tube 5 from the feed hopper 6, the heating plate 23 heats and liquefies the raw materials inside; S2, the molten plastic liquid passes through the filter residue net 24, and enters the interior of the spiral extrusion box 2 through the opened control valve 4 and the feed pipe 3; S3, the spiral extrusion box 2 discharges the molten plastic liquid through the discharge hole 21, and the cutting knife 22 cuts the extruded plastic strips into plastic particles; S4, the spray head 30 in the collection cabinet 25 sprays the water mist formed by the liquid medicine to purify the dust particles and harmful gases in the collection cabinet 25 and cool the extruded plastic strips; S5 , the cut plastic particles fall onto the second filter screen 44 , so that the liquid medicine on the surface of the plastic particles drips along the second filter screen 44 .

[0038] In S1, the following steps are also included: S11, after the raw material is heated and liquefied, the defoaming component performs defoaming treatment on the plastic melt inside the melting cylinder 5; In S4, the following steps are also included: S41, the harmful gas in the collection cabinet 25 is treated by the water mist formed by the liquid medicine, and finally escapes after being further purified by the filter cartridge 38. The installation and fixation of the filter cartridge 38 is facilitated by the fixing assembly.

[0039] Working principle: After the production raw materials are put into the melting tube 5 from the feed hopper 6, the heating plate 23 heats and liquefies the raw materials inside. After the raw materials are heated and liquefied, the defoaming component defoams the plastic melt inside the melting tube 5; The molten plastic liquid passes through the filter screen 24, and enters the interior of the spiral extrusion box 2 through the opened control valve 4 and the feed pipe 3. The spiral extrusion box 2 discharges the molten plastic liquid through the discharge hole 21. The spray head 30 in the collection cabinet 25 sprays the liquid to form a water mist to cool the extruded plastic strips. The rotating cutting knife 22 cuts the extruded plastic strips into plastic particles. The water mist formed by the spray head 30 spraying the liquid medicine can also purify the dust particles and harmful gases in the collection cabinet 25. After the harmful gases in the collection cabinet 25 are treated by the water mist formed by the liquid medicine, they are finally further purified by the activated carbon 41 in the filter cartridge 38 and finally escape to the outside. The fixing assembly facilitates the installation and fixing of the filter cartridge 38. When removing the filter cartridge 38, the staff pulls the pull rod 35 outward to make the protruding block part of the T-shaped block 36 withdraw from the slot 39. At this time, the filter cartridge 38 can be pulled outward to complete the removal of the filter cartridge 38. When installing a new filter cartridge 38, the pull rod 35 is pulled outward to drive the T-shaped block 36 to move into the groove 34, so that the left end of the filter cartridge 38 is pressed and contacts the sealing ring 33 on the limit ring 32, and the filter cartridge 38 is rotated to make the slot 39 correspond to the T-shaped block 36. After loosening the pull rod 35, the T-shaped block 36 enters the slot 39 under the elastic restoring force of the third spring 37, thereby fixing the filter cartridge 38. The fixing assembly facilitates the installation and replacement of the filter cartridge 38 by the staff. The cut plastic particles fall onto the second filter screen 44, so that the liquid medicine on the surface of the plastic particles drips along the second filter screen 44 and is discharged from the inside of the collection cabinet 25 through the drain pipe 45.
