Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically to a pelletizing device for modified masterbatch of insulating materials. Background Technology

[0002] As an effective modification method, modified insulating masterbatch is prepared by mixing, melting, and extruding specific modifiers with base insulating resins to produce modified insulating materials with excellent properties. This provides a more reliable material guarantee for the electrical and electronic fields. In the production process, modified insulating masterbatch needs to be extruded through an extruder, and then granulated by a pelletizing device. The pelletizing device uses high-speed rotating blades or rollers to cut the extruded strips of material into uniform particles, ensuring that the cut particles are of consistent size and regular shape. This improves the filling and flowability of the modified insulating masterbatch, providing a strong guarantee for subsequent processing and application.

[0003] Existing devices have some drawbacks during use. For example, existing pelletizing devices cannot adjust the level between the blades and the extrusion section of the extruder. When the level between the blades and the extrusion section is not parallel, the extruded material will have uneven cut surfaces and burrs due to changes in angle, which reduces the aesthetics and performance of the product. Utility Model Content

[0004] The purpose of this invention is to provide a pelletizing device for modified masterbatch of insulating materials, which solves the problem that existing pelletizing devices cannot adjust the level between the blades and the extrusion section of the extruder.

[0005] This utility model provides the following technical solution: a pelletizing device for modified masterbatch of insulating material, comprising a base, with support feet fixedly connected to the four corners of the lower end face of the base; a first mounting plate and a second mounting plate fixedly connected to both sides of the upper end face of the base; a lead screw disposed between the first mounting plate and the second mounting plate; the two ends of the lead screw passing through the corresponding first mounting plate and the second mounting plate respectively and being rotatably connected to the corresponding first mounting plate and the second mounting plate; a first motor fixedly connected to the outer wall of one side of the first mounting plate; the end of the lead screw near the first motor fixedly connected to the output end of the first motor; and sliding rods fixedly connected between the two ends of the first mounting plate and the second mounting plate; the outer sides of the two sliding rods are respectively... The device has two sliding blocks in a sliding sleeve. A support plate is fixedly connected to the top of each of the four sliding blocks. A movable block is fixedly connected to the lower end of the support plate at a position corresponding to the lead screw, and the movable block is threaded onto the outside of the lead screw. Mounting seats are fixedly connected to both sides of the upper surface of the support plate. A support base is provided between the tops of two mounting seats. Rotating shafts are fixedly connected to the opposite outer walls of the support bases. The ends of the two rotating shafts furthest from the support bases pass laterally through the corresponding mounting seats and are rotatably connected to them. The support bases are rotatably connected to the corresponding mounting seats via the corresponding rotating shafts. A pelletizing assembly for pelletizing is provided on the support base. An angle adjustment assembly for adjusting the angle of the pelletizing assembly is provided on the support plate.

[0006] In the above solution, the first motor drives the lead screw to move the moving block so that the support plate moves along the slide bar through the sliding block. This can achieve precise positioning of the pelletizing component and ensure that it performs cutting operations within the optimal working area. The angle adjustment component can keep the blade horizontal with the extrusion part of the extruder, thereby achieving the best cutting effect.

[0007] As a preferred embodiment of the above technical solution, the pelletizing assembly includes a reducer fixedly connected to the upper surface of the support base. A second motor is fixedly installed on one side of the reducer. The output end of the second motor is used in conjunction with the input end of the reducer. A rotating rod is fixedly connected to the output end of the reducer. A connecting hole is laterally opened at the end of the rotating rod away from the reducer. A connecting rod is slidably connected inside the connecting hole. A blade holder is fixedly connected to the end of the connecting rod away from the rotating rod. Multiple blades are installed on the blade holder by screws.

[0008] In the above solution, the combination of the second motor and the drive reducer enables the blade to cut quickly and stably. The use of the reducer increases the torque, making the cutting process more powerful and able to handle harder materials.

[0009] As a preferred embodiment of the above technical solution, the outer side of the connecting rod is provided with four limiting grooves arranged in a ring array laterally. The inner sidewall of the connecting hole is fixedly connected with a limiting block that is adapted to the size of the limiting groove at the position corresponding to the four limiting grooves. The connecting rod is slidably connected to the limiting block through the limiting groove.

[0010] In the above scheme, the cooperation between the limiting groove and the limiting block keeps the connecting rod stable during rotation and sliding.

[0011] As a preferred embodiment of the above technical solution, a mounting ring is fixedly sleeved on the outer side of the rotating rod away from the tool holder, and a spring is fixedly connected to the outer wall of the mounting ring near the tool holder. The spring is sleeved on the outer side of the rotating rod, and the end of the spring away from the mounting ring is fixedly connected to the outer wall of the tool holder.

[0012] In the above scheme, the preload provided by the spring ensures that the blade fits tightly against the extrusion section of the extruder.

[0013] As a preferred embodiment of the above technical solution, the angle adjustment assembly includes a fixed base fixedly connected to the outer walls of two opposing mounting seats on both sides. A worm gear is laterally arranged between the two fixed bases. The two ends of the worm gear pass through the corresponding fixed bases and are rotatably connected to the corresponding fixed bases. A third motor is fixedly connected to one side of the outer wall of one of the mounting seats at the position corresponding to the worm gear. The end of the worm gear near the third motor is fixedly connected to the output end of the third motor. A sector-shaped worm wheel is fixedly connected to the lower end of the support seat at the position corresponding to the worm gear.

[0014] In the above scheme, the angle adjustment of the sector worm wheel can be precisely controlled by driving the worm gear to rotate through the third motor.

[0015] As a preferred embodiment of the above technical solution, the sector-shaped worm gear is meshed with the worm.

[0016] In the above scheme, the worm gear transmission has a self-locking function. When the worm stops rotating, the sector worm wheel will be locked in the current position and will not change angle due to external force.

[0017] As a preferred embodiment of the above technical solution, retractable casters are fixedly connected to the four corners of the lower end face of the base, corresponding to the positions of the four support feet.

[0018] In the above solution, the retractable casters allow the entire device to be easily moved to the desired working position.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this invention, the angle between the blade and the extrusion part of the extruder is adjusted by the angle adjustment component, so that the blade and the extrusion part of the extruder are kept horizontal. This ensures that the contact surface between the blade and the material is more uniform during cutting, thereby avoiding problems such as uneven cutting surface and burrs caused by mismatched angles.

[0028] Example

[0029] like Figures 1-5As shown, this utility model provides a technical solution: a pelletizing device for modified masterbatch of insulating material, including a base 10, with support feet 11 fixedly connected to the four corners of the lower end face of the base 10. A first mounting plate 12 and a second mounting plate 13 are fixedly connected to both sides of the upper end face of the base 10, respectively. A lead screw 14 is provided between the first mounting plate 12 and the second mounting plate 13, with both ends of the lead screw 14 passing through the corresponding first mounting plate 12 and the corresponding second mounting plate 13 and rotatably connected to them. A first motor 15 is fixedly connected to the outer wall of one side of the first mounting plate 12, and the end of the lead screw 14 near the first motor 15 is fixedly connected to the output end of the first motor 15. Slide rods 16 are fixedly connected between both ends of the second mounting plate 12 and the second mounting plate 13. Two sliding blocks 17 are slidably sleeved on the outer sides of each of the two slide rods 16. A support plate 192 is fixedly connected to the top of each of the four sliding blocks 17. A moving block 18 is fixedly connected to the lower end of the support plate 192 at the position corresponding to the lead screw 14, and the moving block 18 is threaded onto the outer side of the lead screw 14. Mounting seats 19 are fixedly connected to both sides of the upper end of the support plate 192. A support seat 190 is provided between the tops of the two mounting seats 19. Rotating shafts 191 are fixedly connected to the opposite outer walls of the support seats 190. The ends of the two rotating shafts 191 furthest from the support seats 190 transversely pass through the corresponding mounting seats 19 and are rotatably connected to them. The support base 190 is rotatably connected to the corresponding mounting base 19 via a corresponding rotating shaft 191. A pelletizing assembly 2 for pelletizing is provided on the support base 190. An angle adjustment assembly 5 for adjusting the angle of the pelletizing assembly 2 is provided on the support plate 192. Retractable casters 60 are fixedly connected to the four corners of the lower end face of the base 10, corresponding to the positions of the four support feet 11. The pelletizing assembly 2 includes a reducer 201 fixedly connected to the upper end face of the support base 190. A second motor 202 is fixedly installed on one side of the reducer 201. The output end of the second motor 202 cooperates with the input end of the reducer 201. A rotating rod 203 is fixedly connected to the output end of the reducer 201, and the rotating rod 203 is located away from the reducer 201. A connecting hole 204 is laterally opened at one end, and a connecting rod 205 is slidably connected to the inner side of the connecting hole 204. A tool holder 206 is fixedly connected to the end of the connecting rod 205 away from the rotating rod 203. Multiple blades 207 are installed on the tool holder 206 by screws. Four limiting grooves 30 are laterally opened in a circular array on the outer side of the connecting rod 205. A limiting block 31, which is adapted to the size of the limiting groove 30, is fixedly connected to the inner side wall of the connecting hole 204 at the position corresponding to the four limiting grooves 30. The connecting rod 205 is slidably connected to the limiting block 31 through the limiting grooves 30. An installation ring 40 is fixedly sleeved on the outer side of the rotating rod 203 away from the tool holder 206. A spring 41 is fixedly connected to the outer wall of the installation ring 40 on the side near the tool holder 206.Furthermore, the spring 41 is sleeved on the outside of the rotating rod 203, and the end of the spring 41 away from the mounting ring 40 is fixedly connected to the outer wall of one side of the blade holder 206. In actual use, the entire device is moved to a suitable position by means of the retractable universal wheels 60. After the entire device is moved, the retractable universal wheels 60 are adjusted to keep the entire device stable by the support feet 11. Using the angle adjustment component 5, the angle of the pelletizing component 2 is adjusted according to production needs to keep the blade 207 horizontal with the extrusion part of the extruder to achieve the best cutting effect. The first motor 15 drives the lead screw 14 to drive the moving block 18 so that the support plate 192 moves along the slide rod 16 through the sliding block 17. The movement of the support plate 192 drives the pelletizing component 2 to move. During the movement of the pelletizing component 2, the blade 207 gradually comes into contact with the extrusion part of the extruder. During the extrusion process, the blade holder 206 moves along the rotating rod 203 via the connecting rod 205. During this movement, the spring 41 is compressed, and the preload provided by the spring 41 ensures that the blade 207 is in close contact with the extrusion section of the extruder. The second motor 202 is then started, and its output transmits power to the reducer 201. The reducer 201 receives power from the second motor 202, reducing the rotational speed while increasing the torque. The rotating rod 203 rotates at a stable speed, causing the connecting rod 205 and the blade holder 206 to rotate together. The rotation of the blade holder 206 drives the blade 207 to rotate, cutting the material in the extrusion section of the extruder into uniform particles.

[0030] As one implementation method in this embodiment, such as Figure 1 and Figure 3As shown, the angle adjustment assembly 5 includes fixed seats 501 fixedly connected to the outer walls of two opposing mounting seats 19. A worm gear 502 is horizontally arranged between the two fixed seats 501. The two ends of the worm gear 502 pass through the corresponding fixed seats 501 and are rotatably connected to the corresponding fixed seats 501. A third motor 503 is fixedly connected to one side of the outer wall of one of the mounting seats 19 at the position corresponding to the worm gear 502. The end of the worm gear 502 near the third motor 503 is fixedly connected to the output end of the third motor 503. A sector-shaped worm wheel 504 is fixedly connected to the lower end of the support seat 190 at the position corresponding to the worm gear 502. The sector-shaped worm wheel 504 and... The worm gear 502 is engaged. In actual use, the third motor 503 is started, and the power of the third motor 503 is transmitted to the worm gear 502 through the output end, causing the worm gear 502 to start rotating. The rotation of the worm gear 502 drives the sector worm wheel 504, which meshes with it, to adjust its angle. Driven by the worm gear 502, the sector worm wheel 504 rotates along the axial direction of the worm gear 502, thereby realizing the change of angle. Since the sector worm wheel 504 is fixedly connected to the lower end face of the support base 190, the angle adjustment of the sector worm wheel 504 will drive the support base 190 and the pelletizing assembly 2 to adjust their angles, so that the blade 207 and the extrusion part of the extruder remain horizontal.

[0031] Working Principle: The entire device is moved to a suitable position via the retractable casters 60. After the device is moved, the retractable casters 60 are adjusted to ensure stability with the support feet 11. The third motor 503 is started, and its power is transmitted to the worm gear 502 through its output end, causing the worm gear 502 to rotate. The rotation of the worm gear 502 drives the meshing sector worm wheel 504 to adjust its angle. Driven by the worm gear 502, the sector worm wheel 504 rotates along the axial direction of the worm gear 502, thus changing its angle. Since the sector worm wheel 504 is fixedly connected to the lower end face of the support base 190, the angle adjustment of the sector worm wheel 504 will drive the support base 190 and the pelletizing assembly 2 to adjust their angles, keeping the blade 207 horizontal with the extrusion part of the extruder to achieve the best cutting effect. The first motor 15 drives the lead screw 14 to move the moving block 18, causing the support plate 192 to pass through... The sliding block 17 moves along the sliding rod 16, and the movement of the support plate 192 drives the pelletizing assembly 2 to move. During the movement of the pelletizing assembly 2, the blade 207 gradually comes into contact with the extrusion part of the extruder. When the blade 207 comes into contact with the extrusion part of the extruder, the blade holder 206 moves along the rotating rod 203 through the connecting rod 205. During the movement of the blade holder 206, the spring 41 is compressed. The preload provided by the spring 41 makes the blade 207 fit tightly with the extrusion part of the extruder. The second motor 202 is started, and the output end of the second motor 202 transmits power to the reducer 201. The reducer 201 receives the power from the second motor 202 and slows down the speed while increasing the torque. The rotating rod 203 rotates at a stable speed, driving the connecting rod 205 and the blade holder 206 to rotate together. The rotation of the blade holder 206 drives the blade 207 to rotate. The rotating blade 207 cuts the material in the extrusion part of the extruder to form uniform pellets.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
