Abstract
Description
Technical Field
[0001] This utility model relates to the field of masterbatch pelletizing technology, specifically a masterbatch pelletizing device. Background Technology
[0002] Masterbatch pelleting is a crucial step in the production process. It involves cooling and solidifying the molten polymer mixture into appropriately sized pellets. The polymer melt extruded from the extruder needs to be cooled and solidified in a cooling water tank. Circulating water or air is used to rapidly transform the melt into a solid state, forming polymer strips. Cooling water may adhere to the polymer strips after cooling, requiring a blower to dry their surface to ensure they can smoothly enter the pelleting process. Existing pelletizing equipment lacks corresponding screening capabilities, necessitating a second screening process after cutting. This adds a step to the production flow, extending the overall production time. Utility Model Content
[0003] The purpose of this invention is to provide a masterbatch pelletizing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a masterbatch pelletizing device, comprising:
[0005] The device box contains the drive unit;
[0006] A protective cover is placed on top of the equipment box. Inside the protective cover, a pelletizing knife is rotatably connected to the drive unit. Inside the protective cover, a support platform for supporting the material to be cut is fixed. On one side of the support platform, a conveying unit for conveying the material forward is provided.
[0007] The screening section is located inside the equipment box. A sieve plate is installed inside the screening section. An elastic part is provided at the bottom of the sieve plate. An electromagnet is fixed to one side of the sieve plate. A permanent magnet with the same magnetic poles as the electromagnet is provided above the electromagnet. The permanent magnet is connected to the pelletizing knife in a transmission.
[0008] Preferably, the conveying unit includes a first conveying roller and a second conveying roller. Two support plates are fixedly connected inside the protective cover. The pelletizer, the first conveying roller, and the second conveying roller are all rotatably installed between the two support plates. The first conveying roller is located above the second conveying roller. The support platform is fixedly connected to the support plates.
[0009] Preferably, a feed inlet is provided on one side of the protective cover, and a support roller is installed on the side of the protective cover located at the feed inlet.
[0010] Preferably, the drive unit includes a motor fixed inside the equipment housing, the motor being connected to the pelletizer via a synchronous belt assembly, a gear being fixed to one end of the pelletizer, and the conveyor rollers being connected to each other via a spur gear set, with the gear being connected to the gear at the end of the conveyor roller.
[0011] Preferably, the equipment housing is rotatably connected to a second gear that meshes with the first gear, and the permanent magnet is fixed to the outside of the second gear.
[0012] Preferably, the elastic part includes a slide rod fixed to the bottom of the screen plate, the slide rod being slidably connected to the inner wall of the equipment box, and a spring being sleeved on the outside of the slide rod and at the bottom of the screen plate.
[0013] Preferably, a material distribution hopper is installed inside the equipment box and below the sieve plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the device integrates the pelletizing knife and the conveying part into the protective cover, which has a compact structure and a small footprint; through the cooperation of conveying roller one and conveying roller two, synchronous rotation is achieved by using spur gear transmission, and the groove of conveying roller two increases the friction force, which can effectively convey the material forward to the support platform, ensuring that the material enters the cutting area smoothly and improving the cutting efficiency. The screening part uses the principle of repulsion generated by the same magnetic poles of electromagnet and permanent magnet, combined with the elastic part to realize the up and down shaking of the screen plate; when the permanent magnet rotates with gear two, the change in the relative position with the electromagnet causes the repulsive force to change, causing the screen plate to move downward under the action of repulsion force, and then reset under the action of the elastic part. The cyclic shaking realizes the screening of the pelletized material, allowing smaller materials to be discharged from the bottom of the screen plate, effectively separating materials of different particle sizes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this utility model provides a technical solution: a masterbatch pelletizing device, comprising: an equipment box 1 with a drive unit inside; a protective cover 2 fixedly connected to the top of the equipment box 1, a pelletizing blade 4 rotatably connected inside the protective cover 2 and driven by the drive unit, a support platform 7 for supporting the material to be cut fixedly connected inside the protective cover 2, a conveying unit for conveying the material forward on one side of the support platform 7; a screening unit placed inside the equipment box 1, the support platform 7 located between the pelletizing blade 4 and the conveying unit, a screen plate 13 slidably arranged inside the screening unit, an elastic part arranged at the bottom of the screen plate 13, an electromagnet 12 fixedly connected to one side of the screen plate 13, a permanent magnet 11 with the same magnetic poles as the electromagnet 12 arranged above the electromagnet 12, and the permanent magnet 11 being driven by the pelletizing blade 4.
[0025] It should be noted that in this embodiment, a controller and an operation panel are provided. The operation panel controls the drive unit to work. The drive unit drives the pelletizing blade 4 and the conveying unit to move. The plastic to be cut is placed in the protective cover 2. Under the action of the conveying unit, the material box pelletizing blade 4 moves in the direction of the material box. The material moves from the top of the support platform 7 towards the pelletizing blade 4. The pelletizing blade 4 rotates to cut the material that extends out of the top of the support platform 7. A feeding channel is provided on the top of the equipment box 1 below the pelletizing blade 4. The pelletized material enters the screen plate 13. Because the permanent magnet 11 rotates above the electromagnet 12, and the magnetic poles of the electromagnet 12 when energized are the same as the magnetic poles of the permanent magnet 11, the screen plate 13 moves downward under the action of repulsion. When the permanent magnet 11 rotates to the top, the elastic part drives the screen plate 13 to reset, thereby realizing the up and down shaking of the screen plate 13, thereby screening the material falling into the top of the screen plate 13, so that the smaller material is discharged from the bottom of the screen plate 13.
[0026] In one embodiment, the conveying unit includes a first conveying roller 5 and a second conveying roller 6. Two support plates 3 are fixedly connected inside the protective cover 2. The pelletizing knife 4, the first conveying roller 5 and the second conveying roller 6 are rotatably installed between the two support plates 3. The first conveying roller 5 is located above the second conveying roller 6. The support platform 7 is fixedly connected to the support plate 3. A feed inlet is opened on one side of the protective cover 2. A support roller 17 is installed on the side of the protective cover 2 located at the feed inlet.
[0027] It should be noted that in this embodiment, the ends of both conveyor roller 5 and conveyor roller 6 are fixed with the same spur gears. The two spur gears mesh with each other. The top of conveyor roller 6 is provided with multiple grooves along the axial direction to increase friction and convey the material forward. The material is conveyed to the top of the support platform 7, and its part extending from the top of the support platform 7 contacts the pelletizer 4. Under the high-speed rotation of the pelletizer 4, it is cut. The support roller 17 is installed at the entrance on one side of the protective cover 2. Multiple guide grooves are equidistantly provided on the outer side of the support roller 17 to ensure that the material can be conveyed horizontally forward and reduce the probability of tilting during conveying.
[0028] In one embodiment, the pelletizing blade 4 has a hollow structure, and rotary joints are installed at both ends of the pelletizing blade 4.
[0029] It should be noted that in this embodiment, the cooling medium is pumped through a rotary joint to the pelletizer 4 to cool the pelletizer 4. The cooling medium is then pumped out of the pelletizer 4 through the rotary joint at the other end.
[0030] In one embodiment, the drive unit includes a motor 8 fixed inside the equipment housing 1. The motor 8 is connected to the pelletizer 4 via a synchronous belt assembly. One end of the pelletizer 4 is fixedly connected to a gear 9. The conveyor roller 5 and the conveyor roller 6 are connected via a spur gear set. The gear 9 is connected to the gear at the end of the conveyor roller 6. The equipment housing 1 is rotatably connected to a gear 10 that meshes with the gear 9. The permanent magnet 11 is fixed to the outside of the gear 10.
[0031] It should be noted that in this embodiment, the motor 8 drives the synchronous pulley at the end of the pelletizing blade 4 to rotate via the synchronous pulley and synchronous belt, thereby enabling the pelletizing blade 4 to rotate at high speed. At the same time, the pelletizing blade 4 drives the lower gear 10 to rotate via gear 9. Gear 10 drives the permanent magnet 11 to rotate above the electromagnet 12. When the permanent magnet 11 approaches the electromagnet 12, the sieve plate 13 moves downward under the action of repulsive force. When the permanent magnet 11 moves away from the electromagnet 12, it resets under the action of the elastic part. This cycle is used to achieve the up and down shaking of the sieve plate 13, thereby realizing screening.
[0032] In one embodiment, the elastic part includes a slide rod 16 fixed to the bottom of the screen plate 13. The slide rod 16 is slidably connected to the inner wall of the equipment box 1. A spring 14 is sleeved on the outside of the slide rod 16 and at the bottom of the screen plate 13. A material distribution hopper 15 is installed inside the equipment box 1 and below the screen plate 13.
[0033] It should be noted that, in this embodiment, a support beam is welded inside the equipment box 1, the slide rod 16 is slidably connected to the support beam, and the spring 14 is located between the screen plate 13 and the support beam. Under the action of repulsive force, the screen plate 13 drives the slide rod 16 to move downward, and the screen plate 13 compresses the spring 14. When the repulsive force between the permanent magnet 11 and the electromagnet 12 decreases, the spring 14 drives the screen plate 13 to reset.
