Description

Technical Field

[0001] The utility model relates to the technical field of granulating devices, in particular to a PVC cable material granulating device. Background Art

[0002] PVC cable material is particles prepared by taking polyvinyl chloride as the base resin, adding plasticizers such as stabilizers, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate, and inorganic fillers such as calcium carbonate, and mixing, kneading and extruding. The output and scale of PVC resin in China rank first in the world. Correspondingly, various additives and fillers used in PVC modification are also extremely developed, and a complete industrial chain has been formed. This gives China's PVC cable material resource and cost advantages that are difficult to match by other countries, so it has obtained greater development. When producing, it is necessary to granulate through a PVC cable material granulating device to make the material in a granular state.

[0003] In the related art, after the PVC cable material granulating equipment extrudes the cable material for granulation, the extruded material needs to be cooled due to the heat it carries. However, after the existing material is extruded, due to insufficient and poor cooling in time, the material adheres to each other, resulting in poor quality of PVC cable material granulation production. For this reason, we propose a PVC cable material granulating device.

[0004] The above information disclosed in this background art section is only used to understand the background art of the inventive concept, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a PVC cable material granulating device to solve the problem that after the existing material is extruded, due to insufficient and poor cooling in time, the material adheres to each other, resulting in poor quality of PVC cable material granulation production as mentioned in the above background art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A PVC cable material granulation device, comprising a mounting base plate, an extrusion tube, a mounting seat and a cooling coil. Multiple groups of support plates are vertically and spacedly installed at the upper end of the mounting base plate. The extrusion tube is horizontally installed at the upper end of the support plates. A feed tube is provided at the upper left end of the extrusion tube. A heat insulation plate is fixedly installed at the right end of the extrusion tube. A fixing plate is detachably installed on the right side of the heat insulation plate. A mounting seat is integrally formed on the right side of the fixing plate. Multiple groups of cooling fans are symmetrically installed on the side surface of the mounting seat. The cooling fans are fixedly connected to the right side of the fixing plate through brackets. A cooling coil is arranged around the inside of the mounting seat. One end of the cooling coil is communicated with a circulation tube. A water pump is installed on the circulation tube. The lower end of the circulation tube is communicated with the inside of a water tank. A temperature sensor is installed inside the water tank. An outlet plate is integrally formed on the right side of the mounting seat. Multiple groups of outlet holes are regularly arranged on the outlet plate. A collecting cover is detachably installed on the right side of the outlet plate. A driving motor is installed at the central position on the right side of the collecting cover. A transmission shaft is connected to the left output end of the driving motor. The transmission shaft penetrates through the collecting cover and extends into the inside of the collecting cover.

[0008] In some embodiments, cutting knives are symmetrically welded on the side surface of one end of the transmission shaft close to the outlet plate. The ends of the cutting knives far from the transmission shaft are rotatably arranged in the rotation grooves on the inner side of the collecting cover. An outlet groove is provided at the lower end of the side surface of the collecting cover.

[0009] In some embodiments, connecting plates are symmetrically and integrally formed on the peripheral side surfaces of the heat insulation plate. Corresponding connecting plates are provided on the peripheral side surfaces of the fixing plate. Connecting studs are welded on the side of the connecting plate on the heat insulation plate close to the fixing plate.

[0010] In some embodiments, one end of the connecting stud penetrates through the connecting plate on the side surface of the fixing plate, and a fastening nut is provided on the side surface of the connecting stud.

[0011] In some embodiments, heating sleeves are sleeved at intervals on the side surface of the extrusion tube. The heating sleeves are electric heating sleeves.

[0012] In some embodiments, a supplementary water pipe is communicated at the front end of the water tank. A drain pipe is communicated at the front end of the water tank below the supplementary water pipe. Stop valves are provided on the supplementary water pipe and the drain pipe.

[0013] The beneficial effects of the present utility model are:

[0014] By installing multiple groups of cooling fans on the side of the mounting base and arranging cooling coils around the inside of the mounting base, effective cooling of the discharging area is achieved, thereby reducing the adhesiveness of the extruded material. This not only improves the separability of the material after cutting, reduces the adhesion phenomenon, but also ensures the quality and efficiency of granulation, and avoids the difficulties in subsequent processing caused by material adhesion. In the design, the structure of connecting studs and fastening nuts is adopted, making it easy to quickly replace granulation components such as heat insulation plates and fixing plates, significantly reducing the downtime for equipment maintenance and improving the overall production efficiency. The cutting knife equipped at the end of the transmission shaft is ingeniously designed and can accurately cut the extruded material, ensuring the uniformity and consistency of the finished product particles. Combined with the discharge chute and optional conveying device or storage box, orderly collection of the finished product is realized, facilitating subsequent processing and storage. The heating sleeve configured on the side of the extrusion pipe can provide necessary heat control. Combined with the water circulation cooling system (including water tank, water pump, circulation pipe and temperature sensor), precise temperature management during the extrusion process is achieved, which not only ensures the smooth extrusion of the material but also maintains the efficient operation of the entire system. Through the setting of the makeup water pipe and drain pipe, as well as the supporting stop valve, the replenishment and replacement of cooling water become simple and fast, which is beneficial to the system maintenance during long-term operation and the continuous optimization of the cooling effect.

[0023] Refer to Figure 1 、 2, 3, 4, a PVC cable material granulation device, including a mounting base plate 1, an extrusion tube 2, a mounting seat 11 and a cooling coil 23. Multiple groups of support plates 8 are vertically and spacedly installed on the upper end of the mounting base plate 1. The upper end of the support plate 8 is horizontally installed with an extrusion tube 2. A feed tube 3 is opened at the upper left end of the extrusion tube 2. A heat insulation plate 9 is fixedly installed at the right end of the extrusion tube 2. A fixing plate 10 is detachably installed on the right side of the heat insulation plate 9. A mounting seat 11 is integrally formed on the right side of the fixing plate 10. Multiple groups of cooling fans 12 are symmetrically installed on the side surface of the mounting seat 11. The cooling fans 12 are connected and fixed to the right side of the fixing plate 10 through brackets 13. A cooling coil 23 is arranged around the inside of the mounting seat 11. One end of the cooling coil 23 is connected to a circulation pipe 14. A water pump 16 is installed on the circulation pipe 14. The lower end of the circulation pipe 14 is connected to the inside of a water tank 15. A temperature sensor is installed inside the water tank 15. An outlet plate 19 is integrally formed on the right side of the mounting seat 11. Multiple groups of outlet holes 20 are regularly opened on the outlet plate 19. A receiving cover 17 is detachably installed on the right side of the outlet plate 19. A driving motor 18 is installed at the central position on the right side of the receiving cover 17. The left output end of the driving motor 18 is connected with a transmission shaft 21. The transmission shaft 21 penetrates through the receiving cover 17 and extends into the inside of the receiving cover 17. Through the cooling fans 12 arranged on the side surface of the mounting seat 11 and the cooling coil 23 arranged around the inside of the mounting seat 11, before the material is extruded, the area near the outlet plate 19 is cooled, so that the extruded material is cooled, reducing the adhesiveness of the material, preventing mutual adsorption and adhesion after cutting, and ensuring the granulation effect.

[0024] When the embodiment of the present invention is specifically implemented, as Figure 1 , 3 shown, on the side surface of one end of the transmission shaft 21 close to the outlet plate 19, cutting knives 22 are symmetrically welded. The end of the cutting knife 22 far from the transmission shaft 21 is rotatably arranged in a rotating groove on the inner side of the receiving cover 17. An outlet groove 24 is opened at the lower end of the side surface of the receiving cover 17. The cutting knife 22 is close to the outlet plate 19 to ensure the granulation effect. The formed material particles are discharged through the outlet groove 24. A transmission device or a storage box can be arranged at the lower end of the outlet groove 24 to collect the formed material particles, facilitating subsequent use.

[0025] When the embodiment of the present invention is specifically implemented, as Figure 1 , 2As shown, connecting plates 5 are integrally formed symmetrically on the peripheral sides of the heat insulation plate 9. Corresponding connecting plates 5 are provided on the peripheral sides of the fixing plate 10. A connecting stud 7 is welded on the side of the connecting plate on the side of the heat insulation plate 9 close to the fixing plate 10. One end of the connecting stud 7 penetrates through the connecting plate 5 on the side of the fixing plate 10. A fastening nut 6 is provided in a matching manner on the side of the connecting stud 7. Through the connecting stud 7 and the fastening nut 6, it is convenient to replace the granulation assembly, reduce the downtime, and improve the production efficiency. The fixing plate 10 and the mounting seat 11 in the granulation assembly are adapted to the extrusion pipe 2 to ensure the normal progress of the granulation process. The extrusion pipe 2 is a commonly used extrusion pipe in the granulation field and is not particularly limited.

[0026] When the embodiment of the present utility model is specifically implemented, as Figure 1 , 2 shown, heating sleeves 4 are sleeved at intervals on the side of the extrusion pipe 2. The heating sleeves 4 are electric heating sleeves. A supplementary water pipe is connected to the front end of the water tank 15. A drain pipe is connected to the front end of the water tank below the supplementary water pipe. Stop valves are provided on the supplementary water pipe and the drain pipe. The water tank 15 is used to store and convey cooling water, and the supplementary water pipe and the drain pipe can facilitate the replacement of the cooling water.

[0027] In this embodiment, the components are all common standard parts or parts known to those skilled in the art. Their structures and connection principles can be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. The electrical components are uniformly controlled by a controller provided at the rear end of the device. First, the PVC cable material enters the interior of the extrusion tube 2 installed on the support plate 8 through the feed pipe 3. The extrusion tube 2 plays a role in conveying and preliminary processing during this process; the heating sleeve 4 (electric heating sleeve) configured on the side of the extrusion tube 2 heats the incoming raw material to soften and gradually plasticize it, preparing for subsequent extrusion molding; the PVC cable material after heating and plasticization moves in the extrusion direction under the driving force of the screw and is affected by its specific shape through the extrusion tube 2; at the moment when the material is about to leave the extrusion tube 2, the cooling coil 23 inside the mounting seat 11 effectively cools it through the circulating cold water. At the same time, the cooling fan 12 on the side of the mounting seat 11 also assists in reducing the temperature of the discharging area. This measure significantly reduces the adhesiveness of the material and ensures the smooth progress of subsequent cutting and granulation; the transmission shaft 21 drives the cutting knife 22 installed at one end of it to rotate, and cuts the cooled but still plastic material near the discharging plate 19 to form uniform particles. These particles then fall into the material collection cover 17 and are discharged through the discharging groove 24 for easy collection; the cooling water in the water tank 15 circulates through the water pump 16 to maintain the effective operation of the entire cooling system. The temperature sensor installed in the water tank 15 monitors the water temperature to ensure the cooling effect. The presence of the makeup water pipe and the drain pipe allows the makeup or replacement of the cooling water as needed to maintain the system efficiency; if it is necessary to replace or maintain the granulation assembly, it can be easily achieved through the structure of the connecting stud 7 and the fastening nut 6, greatly shortening the equipment downtime and improving the production efficiency.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
