Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to a cable sheathing anti-blocking extruder for cable processing. Background Art

[0002] In plastic extrusion molding equipment, plastic extruder is usually called the main machine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. Plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, films, rods, monofilaments, flat wires, strapping tapes, extruded nets, plates, profiles, granulation, cable coating, etc. to form various plastic extrusion molding production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry now or in the future.

[0003] Traditional plastic extruders use large-particle raw materials during processing. In order to allow the material enough time to melt, the equipment speed needs to be reduced during the processing to increase the material melting time, but this will reduce the overall processing efficiency of the equipment. Similarly, when large-particle raw materials are melted, the outer side of the raw materials is easy to melt, while the middle part is not easy to melt, which will cause unmelted fine particles to be mixed into the finished product, resulting in uneven overall strength distribution of the finished product and reduced quality of the finished product. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cable sheathing anti-blocking extruder for cable processing, comprising a frame, a lifting block is arranged on the top of the frame, and a connecting piece is arranged on the top of the frame;

[0005] A motor, the motor is fixedly mounted on the top of the frame, and the motor is located on one side of the lifting block;

[0006] An extrusion assembly, wherein the extrusion assembly is fixedly mounted on the outside of the lifting block, one end of the extrusion assembly away from the lifting block is fixedly connected to the frame through a connecting piece, and the motor is connected to the extrusion assembly through a transmission piece;

[0007] A feed assembly, the feed assembly is fixedly mounted on one end of the extrusion assembly close to the lifting block, and a feed pipe is fixedly connected to the outer side of the feed assembly;

[0008] A discharging assembly, the discharging assembly being fixedly connected to an end of the extrusion assembly away from the motor;

[0009] Among them, the extrusion assembly includes a fixed cylinder, which is set as a cylinder with a large middle and small ends, the fixed cylinder is fixedly connected to the frame, the inner wall of the fixed cylinder is provided with a rotating shaft, the rotating shaft is connected to the motor through a transmission member, the outer side of the rotating shaft is fixedly connected with a spiral plate, the outer wall of the spiral plate is adapted to the inner wall of the fixed cylinder, the middle part of the rotating shaft is fixedly connected with a limiting cylinder, the cavity of the limiting cylinder is set to be conical, and the outer side of the rotating shaft is fixedly connected with a sleeve. When working, the plastic enters the feed barrel through the feed pipe, and falls into the fixed cylinder under the action of gravity. At this time, the external power supply of the motor works, and the motor drives the rotating shaft to rotate, so that the rotating shaft drives the spiral plate to rotate, and the spiral plate drives the plastic to The plastic is transported in the direction of the discharging component. At this time, the heating plate inside the limiting cylinder heats the plastic, and the plastic is plasticized. By setting the limiting cylinder, the conical melting cavity is used to increase the stroke of the material movement, thereby achieving the improvement of the heating time of the material without changing the length of the existing device, and improving the working efficiency of the device. At the same time, the rotating shaft speed increases. Under the action of centrifugal force and reset spring, the round rod drives the heating plate to move toward the inner wall of the limiting cylinder, so that the distance between the heating plate and the plastic is shortened, so that heat can be transferred to the plastic more quickly, and the heating speed of the plastic is accelerated, which helps to shorten the plasticization time and improve production efficiency, and avoid the high speed that shortens the residence time of the material in the extruder. In order to ensure that the material can be fully plasticized, it is usually necessary to increase the heating temperature accordingly to ensure that a good plasticization effect is achieved in a shorter time. The sleeve is located inside the limiting cylinder, and the outer side of the sleeve is slidably connected with a round rod, and the round rod passes through the sleeve. The end of the round rod away from the sleeve is fixedly connected with a heating plate, and the side of the heating plate close to the round rod is fixedly connected with a reset spring, and the end of the reset spring away from the heating plate is fixedly connected with the sleeve.

[0010] Preferably, the fixed cylinder is fixedly connected to a limiting member near the inside of the discharging assembly, and there are multiple limiting members, which are evenly distributed around the rotating shaft.

[0011] Preferably, the limit member includes a fixed block, which is fixedly connected to the inner wall of the fixed cylinder, an annular groove is provided on the outer side of the fixed block, and a compression spring is fixedly connected to the inner wall of the annular groove, the fixed frame is magnetic, and the magnetic properties of the fixed frame are the same as those of the magnetic plate. In the initial state, the magnetic plate is close to the fixed frame, and under the action of the mutual repulsion between the magnetic plate and the fixed frame, the fixed frame squeezes the compression spring, and the compression spring is deformed under the force, so that the fixed frame drives the clamping plate away from the rotating shaft. At this time, the equipment works normally. When the filter component is blocked, the filter component is forced to drive the magnetic plate to move in the direction away from the fixed frame on the rotating shaft, so that the mutual repulsion between the fixed frame and the magnetic plate becomes smaller, and then the fixed frame moves in the direction of the rotating shaft under the elastic force of the compression spring. At this time, the clamping plate contacts the rotating shaft. By setting a plurality of clamping plates, the equipment stops working after the filter component is blocked. The end of the compression spring away from the fixed block is fixedly connected to the fixed frame, and the fixed frame is slidably connected to the fixed block through the annular groove. The end of the fixed frame away from the compression spring is fixedly connected to the clamping plate.

[0012] The discharge assembly comprises a cylinder, which is fixedly connected to a fixed cylinder, an end of the cylinder away from the fixed cylinder is fixedly connected to a discharge pipe, and an inner wall of the cylinder is fixedly connected to a filter assembly.

The molten material particles are stacked to help disperse the pressure of the melt, make the extrusion more uniform, and extend the service life of the filter assembly. At the same time, a spring plate is set to play a buffering role. The end of the spring plate away from the second filter plate is fixedly connected to the third filter plate, and the third filter plate is slidably connected to the rotating shaft. The first filter plate, the second filter plate and the third filter plate are connected by the spring plate, and the diameters of the first filter plate, the second filter plate and the third filter plate decrease successively. The end of the third filter plate away from the second filter plate is fixedly connected to the magnetic plate, and the magnetic plate is slidably connected to the rotating shaft.

[0014] Preferably, the feed assembly includes a feed barrel, which is fixedly connected to a fixed barrel, and a motor is fixedly connected to the top of the feed barrel, which is fan-shaped through a rotating plate so that the rotating plate can block the connection between the feed pipe and the feed barrel. When working, the motor is connected to an external power supply, and the motor drives the rotating rod to rotate, and the rotating rod drives the rotating plate to rotate, so that the rotating plate is away from the connection between the feed pipe and the feed barrel, so that the plastic can be added to the inside of the feed barrel from the feed pipe, and then the material is fed indirectly, so that the feeding is uniform, and blockage at the feed point caused by a large amount of material is avoided. The output end of the motor passes through the feed barrel, and the feed barrel is fixedly connected to the feed pipe. A circular plate is fixedly connected to the inner wall of the feed barrel close to the fixed barrel, and filter holes are provided on the outer side of the circular plate. By setting the filter plate, foreign matter such as metal, stone, fiber, etc. can be prevented from being mixed into the plastic raw material. These impurities can be removed by the filter plate to prevent them from entering the extruder and damaging the equipment or affecting the material. The invention relates to a method for screening the crushed plastic and making the size of the plastic particles entering the extruder more uniform, which is beneficial to improving the stability of the extrusion process and the consistency of product quality. The feed barrel is fixedly connected with a filter plate near the inner wall of the feed pipe, and the output end of the motor is fixedly connected with a rotating rod, and the outer side of the rotating rod is fixedly connected with a fixing seat. The plastic raw material passing through the filter plate falls into the gap between the fixing seat and the feed barrel. At this time, the rotating rod drives the fixing seat to rotate, so that the crushing rod crushes the plastic and breaks it into smaller particles. The specific surface area of ​​the crushed plastic particles is increased, and it is easier to be heated and plasticized during the extrusion process, which is beneficial to improving production efficiency and product quality. The fixing seat is located in the middle of the circular plate and the filter plate, and the outer wall of the fixing seat is fixedly connected with a crushing rod, and one end of the rotating rod close to the circular plate is fixedly connected with a straight rod, and the rotating rod is fixedly connected with a rotating plate close to the outer side of the filter plate.

[0017] 2. The cable sheathing anti-blocking extruder for cable processing uses a round rod to drive the heating plate to move toward the inner wall of the limiting cylinder under the action of centrifugal force and a reset spring, thereby shortening the distance between the heating plate and the plastic, so that heat can be transferred to the plastic more quickly, accelerating the heating rate of the plastic, helping to shorten the plasticizing time, improve production efficiency, and avoid the situation where a higher rotation speed will shorten the residence time of the material in the extruder.

[0018] 3. The cable sheathing anti-blocking extruder for cable processing drives the magnetic plate to move in the direction of the rotating shaft away from the fixed frame through the force of the filter component, so that the mutual repulsion between the fixed frame and the magnetic plate becomes smaller, and then the fixed frame moves toward the direction of the rotating shaft under the elastic force of the compression spring. At this time, the clamping plate contacts the rotating shaft. By setting up multiple clamping plates, the equipment stops working after the filter component is blocked.

[0019] 4. The cable sheathing anti-blocking extruder for cable processing filters the plastic in a molten state by setting a first filter plate, a second filter plate and a third filter plate, removes impurities and unmelted material particles in the plastic melt, and through the stacking setting, it helps to disperse the pressure of the melt, make the extrusion more uniform, and extend the service life of the filter component.

[0020] 5. The cable sheathing anti-blocking extruder for cable processing, the plastic raw material passes through the filter plate and falls into the gap between the fixed seat and the feed barrel. At this time, the rotating rod drives the fixed seat to rotate, so that the crushing rod crushes the plastic and breaks it into smaller particles.

[0035] A discharging assembly 6, which is fixedly connected to an end of the extrusion assembly 3 away from the motor 2;

[0036] Wherein, the extrusion assembly 3 includes a fixed cylinder 31, which is set as a cylinder with a large middle and small ends, and the fixed cylinder 31 is fixedly connected to the frame 1. The inner wall of the fixed cylinder 31 is provided with a rotating shaft 32, and the rotating shaft 32 is connected to the motor 2 through a transmission member. The outer side of the rotating shaft 32 is fixedly connected with a spiral plate 33, and the outer wall of the spiral plate 33 is adapted to the inner wall of the fixed cylinder 31. The middle part of the rotating shaft 32 is fixedly connected with a limiting cylinder 34, and the cavity of the limiting cylinder 34 is set to be conical, and the outer side of the rotating shaft 32 is fixedly connected with a sleeve 36. When working, the plastic enters the inside of the feeding barrel 41 through the feeding pipe 5, and falls into the fixed cylinder 31 under the action of gravity. At this time, the motor 2 is connected to the external power supply to work, and the motor 2 drives the rotating shaft 32 to rotate, so that the rotating shaft 32 drives the spiral plate 33 to rotate, and the spiral plate 33 The plastic is driven to be transported in the direction of the discharge component 6. At this time, the heating plate 39 inside the limiting cylinder 34 heats the plastic, and the plastic is plasticized. By setting the limiting cylinder 34 and utilizing the conical melting cavity to increase the travel of the material movement, the heating time of the material is increased without changing the length of the existing device, thereby improving the working efficiency of the device. At the same time, the rotation speed of the rotating shaft 32 is increased. Under the action of centrifugal force and the return spring 37, the round rod 38 drives the heating plate 39 to move toward the inner wall of the limiting cylinder 34, so that the distance between the heating plate 39 and the plastic is shortened, so that heat can be transferred to the plastic more quickly, and the heating speed of the plastic is accelerated, which helps to shorten the plasticization time, improve production efficiency, and avoid the high rotation speed that shortens the residence time of the material in the extruder. In order to ensure that the material can be fully plasticized, it is usually necessary to increase the heating temperature accordingly to ensure that a good plasticizing effect is achieved in a shorter time. The sleeve 36 is located inside the limiting cylinder 34, and the outer side of the sleeve 36 is slidably connected to a round rod 38, which passes through the sleeve 36, and the end of the round rod 38 away from the sleeve 36 is fixedly connected to a heating plate 39, and the side of the heating plate 39 close to the round rod 38 is fixedly connected to a return spring 37, and the end of the return spring 37 away from the heating plate 39 is fixedly connected to the sleeve 36.

[0037] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the fixed cylinder 31 is fixedly connected to the inner part of the discharging assembly 6 with a limiting member 35 . There are multiple limiting members 35 , and the multiple limiting members 35 are evenly distributed around the rotating shaft 32 .

[0038] The limiting member 35 includes a fixing block 351, which is fixedly connected to the inner wall of the fixing cylinder 31. An annular groove 352 is provided on the outer side of the fixing block 351. A compression spring 353 is fixedly connected to the inner wall of the annular groove 352. The fixing frame 354 is magnetic. The fixing frame 354 has the same magnetism as the magnetic plate 625. In the initial state, the magnetic plate 625 is close to the fixing frame 354. Under the action of the mutual repulsion between the magnetic plate 625 and the fixing frame 354, the fixing frame 354 squeezes the compression spring 353. The compression spring 353 is deformed by the force, so that the fixing frame 354 drives the clamping plate 355 away from the rotating shaft 32. At this time, the equipment works normally. When the filter component 62 is blocked, the filter element 62 is blocked. The filter assembly 62 is driven by the force to move the magnetic plate 625 in the direction away from the fixed frame 354 on the rotating shaft 32, so that the mutual repulsion between the fixed frame 354 and the magnetic plate 625 becomes smaller, and then the fixed frame 354 moves in the direction of the rotating shaft 32 under the elastic force of the compression spring 353. At this time, the clamping plate 355 is in contact with the rotating shaft 32. By setting a plurality of clamping plates 355, the equipment stops working after the filter assembly 62 is blocked. The end of the compression spring 353 away from the fixed block 351 is fixedly connected to the fixed frame 354, and the fixed frame 354 is slidably connected to the fixed block 351 through the annular groove 352. The end of the fixed frame 354 away from the compression spring 353 is fixedly connected to the clamping plate 355.

[0039] The discharge assembly 6 includes a cylinder 61 , which is fixedly connected to the fixed cylinder 31 , an end of the cylinder 61 away from the fixed cylinder 31 is fixedly connected to a discharge pipe 63 , and an inner wall of the cylinder 61 is fixedly connected to a filter assembly 62 .

[0040] The filter assembly 62 includes a fixing ring 621, which is fixedly connected to the inner wall of the cylinder 61, a first filter plate 622 is fixedly connected to the outer side of the fixing ring 621, the first filter plate 622 is slidably connected to the rotating shaft 32, a spring plate 626 is fixedly connected to the side of the first filter plate 622 away from the fixing ring 621, a second filter plate 623 is fixedly connected to the end of the spring plate 626 away from the first filter plate 622, the second filter plate 623 is slidably connected to the rotating shaft 32, and a spring plate 626 is fixedly connected to the outer side of the second filter plate 623. By arranging the first filter plate 622, the second filter plate 623 and the third filter plate 624, the plastic in the molten state is filtered to remove impurities and unmelted plastic in the plastic melt. The material particles are stacked and arranged, which helps to disperse the pressure of the melt, make the extrusion more uniform, and extend the service life of the filter assembly 62.

The end of the third filter plate 624 away from the second filter plate 623 is fixedly connected to the magnetic plate 625, and the magnetic plate 625 is slidably connected to the rotating shaft 32.

[0041] The third embodiment is based on the first and second embodiments. Figure 8As shown, the feed assembly 4 includes a feed barrel 41, which is fixedly connected to the fixed cylinder 31, and a motor 42 is fixedly connected to the top of the feed barrel 41. The rotating plate 47 is set to be fan-shaped, so that the rotating plate 47 can block the connection between the feed pipe 5 and the feed barrel 41. When working, the motor 42 is connected to an external power supply, and the motor 42 drives the rotating rod 43 to rotate, and the rotating rod 43 drives the rotating plate 47 to rotate, so that the rotating plate 47 is away from the connection between the feed pipe 5 and the feed barrel 41, so that the plastic can be added to the feed from the feed pipe 5. The inside of the barrel 41 is indirectly fed, so that the feeding is uniform and the clogging of the feeding place caused by a large amount of feeding is avoided. The output end of the motor 42 passes through the feed barrel 41, and the feed barrel 41 is fixedly connected to the feed pipe 5. The inner wall of the feed barrel 41 close to the fixed cylinder 31 is fixedly connected with a circular plate 45. The outer side of the circular plate 45 is provided with a filter hole. By setting a filter plate 46, foreign matter such as metal, stone, fiber, etc. can be prevented from being mixed into the plastic raw material. These impurities can be removed by the filter plate 46 to prevent them from entering the extruder and damaging it. The equipment may affect the product quality. By setting a circular plate 45, the crushed plastic is screened so that the size of the plastic particles entering the extruder is more uniform, which is beneficial to improving the stability of the extrusion process and the consistency of product quality. The inner wall of the feed barrel 41 near the feed pipe 5 is fixedly connected with a filter plate 46, the output end of the motor 42 is fixedly connected with a rotating rod 43, and the outer side of the rotating rod 43 is fixedly connected with a fixed seat 44. The plastic raw material passing through the filter plate 46 falls into the gap between the fixed seat 44 and the feed barrel 41. At this time, the rotating rod 43 drives the fixed seat 44 to rotate, so that the crushing rod 49 crushes the plastic and breaks it into smaller particles. The specific surface area of ​​the crushed plastic particles is increased, and it is easier to heat and plasticize during the extrusion process, which is helpful to improve production efficiency and product quality. The fixed seat 44 is located between the circular plate 45 and the filter plate 46, and the outer wall of the fixed seat 44 is fixedly connected with a crushing rod 49. The end of the rotating rod 43 near the circular plate 45 is fixedly connected with a straight rod 48, and the outer side of the rotating rod 43 near the filter plate 46 is fixedly connected with a rotating plate 47.

[0042] When in use, the motor 42 is connected to an external power source to work, and the motor 42 drives the rotating rod 43 to rotate, and the rotating rod 43 drives the rotating plate 47 to rotate, so that the rotating plate 47 is away from the connection between the feed pipe 5 and the feed barrel 41, so that the plastic can be added to the inside of the feed barrel 41 from the feed pipe 5, and then indirectly fed, so that the feeding is uniform, and these impurities can be removed by the filter plate 46 to prevent them from entering the extruder and damaging the equipment or affecting the product quality. The plastic raw material passes through the filter plate 46 and falls into the gap between the fixed seat 44 and the feed barrel 41. At this time, the rotating rod 43 drives the fixed seat 44 to rotate, so that the crushing rod 49 crushes the plastic and breaks it into smaller particles. Then, the crushed plastic is screened through the circular plate 45, so that the size of the plastic particles entering the extruder is relatively uniform, which is beneficial to improving the stability of the extrusion process and the consistency of product quality.

[0043] The plastic enters the feed barrel 41 through the feed pipe 5, and falls into the fixed cylinder 31 under the action of gravity. At this time, the external power supply of the motor 2 is working, and the motor 2 drives the rotating shaft 32 to rotate, so that the rotating shaft 32 drives the spiral plate 33 to rotate, and the spiral plate 33 drives the plastic to be transported in the direction of the discharge component 6. At this time, the heating plate 39 inside the limiting cylinder 34 heats the plastic, and the plastic is plasticized. By setting the limiting cylinder 34 and utilizing the conical melting cavity to increase the stroke of the material movement, it is achieved that the heating time of the material is increased without changing the length of the existing device, and the working efficiency of the device is improved. At the same time, the rotation speed of the rotating shaft 32 increases. Under the action of centrifugal force and the return spring 37, the round rod 38 drives the heating plate 39 to move toward the inner wall of the limiting cylinder 34, so that the distance between the heating plate 39 and the plastic is shortened, so that the heat can be transferred to the plastic more quickly, the heating speed of the plastic is accelerated, which helps to shorten the plasticization time and improve production efficiency.

[0044] The fixed frame 354 has the same magnetic properties as the magnetic plate 625. In the initial state, the magnetic plate 625 is close to the fixed frame 354. Under the action of the mutual repulsion between the magnetic plate 625 and the fixed frame 354, the fixed frame 354 squeezes the compression spring 353. The compression spring 353 is deformed by the force, so that the fixed frame 354 drives the clamping plate 355 away from the rotating shaft 32. At this time, the equipment works normally. When the filter component 62 is blocked, the filter component 62 is forced to drive the magnetic plate 625 to move away from the fixed frame 354 on the rotating shaft 32, so that the mutual repulsion between the fixed frame 354 and the magnetic plate 625 becomes smaller, and then the fixed frame 354 moves toward the direction of the rotating shaft 32 under the elastic force of the compression spring 353. At this time, the clamping plate 355 is in contact with the rotating shaft 32. By setting a plurality of clamping plates 355, the equipment stops working after the filter component 62 is blocked.
