A pelletizer blade adjustment device

Abstract

This utility model discloses a pelletizer blade adjustment device, belonging to the technical field. The device includes a fixed plate, with a second fixed plate on its outer wall, an adjustment mechanism, a locking mechanism, and a collection mechanism. By manually rotating a knob, the worm gear rotates, causing the worm wheel to rotate, which in turn rotates the threaded rod. This rotation of the threaded rod causes the second sliding block to slide within a groove, thus moving the rotating shaft. The rotating shaft then moves the motor, which in turn moves the first sliding block within the groove. This mechanism allows for manual adjustment of the distance between the blade and the second fixed plate according to the material characteristics, ensuring uniform particle size, improving cutting accuracy, and meeting production requirements.

Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a pelletizer blade adjustment device. Background Technology

[0002] A pelletizer is a piece of equipment commonly used in industries such as plastics, rubber, chemicals, and food. It is mainly used to cut large pieces of material into small particles or granular materials. These materials are cut to the required particle size through the high-speed movement and relative position of the blades. For different types of materials and production requirements, the design and adjustment of the pelletizer blades become crucial.

[0003] According to the published patent CN211566577U, an adjustable plastic pelletizer includes a pelletizing box, an air pump at the top of the pelletizing box, a discharge port on the lower surface of the pelletizing box, and a motor at the bottom. The pelletizing box has a feeding trough inside, and a feeding device is installed above the feeding trough. The air pump is connected to an outer rod and an inner rod inside the pelletizing box. The outer rod is sleeved on the outside of the inner rod, and a pressure plate is connected below the inner rod. A rotating shaft is connected to one side of the feeding trough, and the rotating shaft is connected to the motor via a belt. A blade is sleeved on the outside of the rotating shaft, and a screw is connected to one side of the blade. The screw is connected to an adjustment knob. This invention solves the problem that traditional pelletizers cannot adjust the position of the cutting blades, resulting in uniform plastic pellet sizes. It introduces adjustable blades to cut plastic pellets of custom sizes, facilitating further processing of different types of plastic pellets. However, it still has the following shortcomings:

[0004] The mechanism adjusts the position of the blades by means of a screw, but the screw itself does not have a self-locking function. During long-term use, the position of the blades may deviate, making it impossible for the blades to maintain an accurate cutting angle. Therefore, we propose a pelletizer blade adjustment device. Summary of the Invention

[0005] The purpose of this invention is to provide a pelletizer blade adjustment device. When the rotating shaft moves, it drives the limiting block to move, thereby causing the limiting block to engage inside the knob, thus solving the problem of possible blade position deviation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a pelletizer blade adjustment device, including a fixing plate, a second fixing plate provided on the outer wall of the fixing plate, an adjustment mechanism provided on the fixing plate, a locking mechanism provided on the fixing plate, and a collection mechanism provided on the fixing plate;

[0008] The adjustment mechanism includes a fixed block 1 fixedly connected to the outer wall of a fixed plate, a controller fixedly connected to the outer wall of the fixed block 1, a sliding groove 1 inside the fixed block 1, a sliding block 1 slidably connected to the inner wall of the sliding groove 1, a motor fixedly connected to the inner wall of the sliding block 1, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, a round shaft fixedly connected to the outer wall of the rotating shaft, a blade fixedly connected to the outer wall of the round shaft, a second sliding block 2 rotatably connected to the rotating shaft away from the motor, a second fixed block 2 fixedly connected to the outer wall of the fixed plate, a second sliding groove 2 inside the fixed block 2, and a threaded rod threadedly connected to the inner wall of the second sliding block 2.

[0009] Furthermore, a total of several blades are provided, the inner wall of the second sliding groove is slidably connected to the outer wall of the second sliding block, and the outer wall of the threaded rod is rotatably connected to the outer wall of the fixed plate.

[0010] Furthermore, the locking mechanism includes a worm gear fixedly connected to the outer wall of the threaded rod, a worm engaging with the outer wall of the worm gear, the outer wall of the worm being rotatably connected to the inner wall of the second fixed block, and a knob fixedly connected to the outer wall of the worm.

[0011] Furthermore, a limiting block is engaged with the inner wall of the knob, a second rotating shaft is fixedly connected to the outer wall of the limiting block, a third fixing block is rotatably connected to the outer wall of the second rotating shaft, and a telescopic rod is fixedly connected to the outer wall of the third fixing block.

[0012] Furthermore, the outer wall of the telescopic rod is fixedly connected to the outer wall of the second fixed block, and the outer wall of the third fixed block is fixedly connected to a spring. The end of the spring away from the third fixed block is fixedly connected to the outer wall of the second fixed block, and the telescopic rod is located inside the spring.

[0013] Furthermore, the collecting mechanism includes a through groove inside the fixed plate, and a fixed frame is fixedly connected to the bottom of the fixed plate. There are two fixed frames, and a telescopic rod is fixedly connected to the inner wall of the fixed frame.

[0014] Furthermore, a locking block is fixedly connected to the outer wall of the telescopic rod two, and a spring is fixedly connected to the side of the locking block near the telescopic rod two.

[0015] Furthermore, a collection shell is fixedly connected to the outer wall of the fixed column, a sliding groove three is provided inside the card block, a fixed column two is slidably connected to the inner wall of the sliding groove three, a sliding groove four is provided inside the fixed frame, and the inner wall of the sliding groove four is slidably connected to the outer wall of the fixed column two.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a blade, firstly, manually rotates the knob to drive the worm gear to rotate. When the worm gear rotates, it drives the worm wheel to rotate, thereby causing the threaded rod to rotate. When the threaded rod rotates, it drives the sliding block two to slide in the sliding groove two, thereby driving the rotating shaft to move. When the rotating shaft moves, it drives the motor to move, which in turn drives the sliding block one to move in the sliding groove one, thereby changing the distance between the blade and the fixed plate two. This mechanism can manually adjust the distance between the blade and the fixed plate two according to the characteristics of the material, thereby ensuring the uniformity of the cutting particle size, improving the cutting accuracy, and meeting production needs.

[0018] 2. This utility model features a collection housing. After cutting, the particles fall into the collection housing through the through groove. After the cutting is completed, the second fixing column is manually moved upward, causing it to slide in the fourth sliding groove. This causes the locking block to move, and as the locking block moves, it squeezes the second telescopic rod and the spring. This mechanism can collect the cut particles in a timely and effective manner, avoiding scattering and waste, thereby ensuring the continuity and efficient operation of the production line.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a pelletizer blade adjustment device, including a fixing plate 101, a fixing plate 2 102 provided on the outer wall of the fixing plate 101, an adjustment mechanism 2 provided on the fixing plate 101, a locking mechanism 3 provided on the fixing plate 101, and a collecting mechanism 4 provided on the fixing plate 101.

[0030] The adjusting mechanism 2 includes a fixed block 201 fixedly connected to the outer wall of the fixed plate 101. A controller 202 is fixedly connected to the outer wall of the fixed block 201. A slide groove 203 is provided inside the fixed block 201. A sliding block 204 is slidably connected to the inner wall of the slide groove 203. By setting the slide groove 203, when the sliding block 204 slides inside the slide groove 203, the slide groove 203 will limit the movement position of the sliding block 204, so that it maintains a linear upward or linear downward movement. The inner wall of the sliding block 204 is fixedly connected to the controller 202. A motor 205 is fixedly connected to the rotating shaft 206 via a coupling. A circular shaft 207 is fixedly connected to the outer wall of the rotating shaft 206, and a blade 208 is fixedly connected to the outer wall of the circular shaft 207. The motor 205 is started by a controller 202, which drives the rotating shaft 206 to rotate. As the rotating shaft 206 rotates, it drives the circular shaft 207 to rotate, which in turn drives the blade 208 to perform circular motion. A sliding block 209 is connected to the rotating shaft 206, which is rotatably connected away from the motor 205. A fixing block 210 is fixedly connected to the outer wall of the fixing plate 101. A sliding groove 211 is provided inside the fixing block 210. A threaded rod 212 is threadedly connected to the inner wall of the sliding block 209. By setting the threaded rod 212, when the threaded rod 212 rotates, it will drive the sliding block 209 to slide within the sliding groove 211. The sliding groove 211 will limit the sliding block 209, causing it to rise or fall linearly. Several blades 208 are provided. The inner wall of the sliding groove 211 and the sliding... The outer wall of block 209 is slidably connected, the outer wall of threaded rod 212 is rotatably connected to the outer wall of fixed plate 101, and the locking mechanism 3 includes a worm wheel 301 fixedly connected to the outer wall of threaded rod 212. By setting blade 208, when blade 208 rotates in a circle, it uses its own shearing force to cut the long strip material that slides into the upper part of fixed plate 102 into granules. The outer wall of worm wheel 301 is engaged with worm 302, the outer wall of worm 302 is rotatably connected to the inner wall of fixed block 210, and a knob 303 is fixedly connected to the outer wall of worm 302.

[0031] A limit block 304 is engaged with the inner wall of the knob 303. A rotating shaft 305 is fixedly connected to the outer wall of the limit block 304. A fixing block 306 is rotatably connected to the outer wall of the rotating shaft 305. A telescopic rod 307 is fixedly connected to the outer wall of the fixing block 306. By manually rotating the knob 303, the worm gear 302 is driven to rotate. When the worm gear 302 rotates, it drives the worm wheel 301 to rotate, thereby causing the threaded rod 212 to rotate. The outer wall of the telescopic rod 307 is fixedly connected to the outer wall of the fixing block 210. A spring 308 is fixedly connected to the outer wall of the fixing block 306. The end of the spring 308 away from the fixing block 306 is fixedly connected to the outer wall of the fixing block 210. The telescopic rod 307 is located inside the spring 308. On the side, a spring 308 is provided. Since the spring 308 has its own tension, it will pull the fixed block 306 to move, thereby causing the rotating shaft 305 to move. When the rotating shaft 305 moves, the limiting block 304 will be inserted into the inner wall of the knob 303, thereby fixing the angle of the knob 303. The collecting mechanism 4 includes a through groove 401 opened inside the fixed plate 101. A fixed frame 402 is fixedly connected to the bottom of the fixed plate 101. There are two fixed frames 402. A telescopic rod 403 is fixedly connected to the inner wall of the fixed frame 402. By providing the through groove 401, when the material is cut into granules, it will flow into the bottom of the device through the through groove 401 for convenient unified collection.

[0032] A locking block 404 is fixedly connected to the outer wall of the telescopic rod 403. A spring 405 is fixedly connected to the side of the locking block 404 near the telescopic rod 403. The end of the spring 405 away from the locking block 404 is fixedly connected to the inner wall of the fixed frame 402. The telescopic rod 403 is located inside the spring 405. By setting the spring 405, due to the reaction force of the spring 405, it will continuously compress the locking block 404, thereby enabling the locking block 404 to have a clamping and fixing function. The inner wall of the locking block 404 is engaged. There is a fixed column 406, and a collection shell 407 is fixedly connected to the outer wall of the fixed column 406. A sliding groove 408 is opened inside the locking block 404, and a fixed column 409 is slidably connected to the inner wall of the sliding groove 408. By setting up the collection shell 407, it is convenient to collect the particles falling from the through groove 401 in a unified manner, avoid scattering and waste, and ensure the continuity and efficient operation of the production line. A sliding groove 410 is opened inside the fixed frame 402, and the inner wall of the sliding groove 410 is slidably connected to the outer wall of the fixed column 409.

[0033] One specific application of this embodiment is:

[0034] First, manually turn knob 303 to rotate worm gear 302. As worm gear 302 rotates, it drives worm wheel 301 to rotate, causing threaded rod 212 to rotate. Simultaneously, threaded rod 212 rotates, causing sliding block 209 to slide within groove 211, thus moving rotating shaft 206. The movement of rotating shaft 206 moves motor 205, which in turn moves sliding block 204 within groove 203, changing the distance between blade 208 and fixed plate 102. After adjustment, pull limit block 304 outwards, moving rotating shaft 305 and thus fixed block 306. When the fixed block 306 moves, it stretches the telescopic rod 307 and the spring 308. Then, the limiting block 304 rotates around the fixed block 306, aligning the limiting block 304 with the inside of the knob 303. Then, the limiting block 304 is released. At this time, due to the reaction force of the spring 308, the fixed block 306 is pulled by the spring 308, which in turn drives the rotating shaft 305 to move. When the rotating shaft 305 moves, it drives the limiting block 304 to move, causing the limiting block 304 to engage with the inside of the knob 303, fixing the rotation angle of the knob 303. Then, the controller 202 starts the motor 205, driving the rotating shaft 206 to rotate. As the rotating shaft 206 rotates, it drives the rotating shaft 207 to rotate, which in turn drives the blade 208 to perform a circular motion. This mechanism allows manual adjustment of the distance between the blade 208 and the fixed plate 102 according to the characteristics of the material, thereby ensuring uniform cutting particle size, improving cutting accuracy, and meeting production requirements. After cutting, the particles fall into the collection housing 407 through the through groove 401. After the cutting is completed, the fixed column 409 is manually moved upward, causing it to slide in the slide groove 410, thereby moving the locking block 404. When the locking block 404 moves, it compresses the telescopic rod 403 and the spring 405, and then moves the fixed column 409 along the direction of the slide groove 408. 09, allowing the slide 410 to lock the position of the fixed post 409, thereby fixing the position of the locking block 404. Then, the collecting shell 407 can be removed to collect the particles inside. After the collecting shell 407 is put back in its original position, the fixed post 409 slides in the opposite direction along the slide 3 408. At this time, since the slide 410 cannot limit the fixed post 409, the spring 405 will squeeze the locking block 404 due to its own reaction force, thereby fixing the position of the locking block 404, and thus fixing the position of the collecting shell 407. This mechanism can collect the cut particles in a timely and effective manner, avoiding scattering and waste, thereby ensuring the continuity and efficient operation of the production line.
