Technical Field

[0001] This utility model relates to the field of plastic processing, and in particular to a high-efficiency continuous plastic pelletizing device. Background Technology

[0002] High heat-resistant glass fiber reinforced ABS material is a composite material with acrylonitrile-butadiene-styrene copolymer (ABS) as the matrix and glass fiber (GF) as the reinforcing phase. In the production and processing of high heat-resistant glass fiber reinforced ABS material, plastic pelletizing equipment is required to pelletize the raw materials or semi-finished products of high heat-resistant glass fiber reinforced ABS material into specified specifications, shapes and sizes.

[0003] The existing technology has the following drawbacks: traditional plastic pelletizing equipment often has many shortcomings. In the screening stage, the screening device is mostly statically designed, and the material is prone to accumulate and block the screen during the screening process, resulting in low screening efficiency. Frequent shutdowns to clean the blockages not only consume a lot of time, but also seriously affect the overall production progress, making the plastic pelletizing process intermittent and difficult to meet the needs of high-efficiency production. Therefore, a high-efficiency and continuous plastic pelletizing equipment is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-efficiency continuous plastic pelletizing device, including a cutting box 1. A door 2 is hinged to the outer wall of the cutting box 1, allowing for the replacement of the cutting blade 6 by opening the door 2, ensuring the stability of subsequent pelletizing of high heat-resistant glass fiber reinforced ABS material. A feeding hopper 3 is fixedly connected to the inner wall of the cutting box 1, through which the cut plastic pellets are discharged. An existing collection bucket can be placed at the bottom of the feeding hopper 3. A hydraulic rod 4 is installed through the inner wall of the cutting box 1, allowing the cutting blade 6 to move vertically, enabling pelletizing of high heat-resistant glass fiber reinforced ABS material, thus providing a new type of plastic pelletizing equipment. The technical details are omitted here. The bottom of the hydraulic rod 4 is fixedly connected to the mounting bracket 5. The mounting bracket 5 mainly connects to and supports the cutting blade 6. The cutting blade 6 is detachably installed on the inner wall of the mounting bracket 5. The side wall of the mounting bracket 5 is fixedly connected to the L-frame 7. The inner wall of the cutting box 1 is fixedly connected to the guide rod 10. The guide rod 10 allows the slider 9 to move back and forth without deviation from the movement trajectory. The inner wall of the cutting box 1 is equipped with a screening mechanism. The top of the screening mechanism is fixedly connected to the wedge block 12. The wedge block 12 is inclined. When the inclined surface is squeezed, it will cause the wedge block 12 to move along with the screening frame 11. The inner wall of the mounting bracket 5 is equipped with a limit component.

[0032] The screening mechanism includes a slider 9, which is slidably connected to the inner wall of the cutting box 1. The cutting box 1 has a corresponding slot for the slider 9, which allows the slider 9 to move back and forth. The outer wall of the slider 9 is elastically connected to the cutting box 1 through a return spring 8. A screening frame 11 is fixedly connected to the side wall of the slider 9. A filter screen is provided on the screening frame 11, which can screen the cut particles through the filter screen to prevent the collection of particles of poor quality.

[0033] Reference Figure 3 - Figure 4 The limiting component includes a limiting block 13, which is inclined. When the inclined surface is squeezed, the limiting block 13 will move vertically. The limiting block 13 is slidably connected to the inner wall of the mounting frame 5. The inner side wall of the limiting block 13 is elastically connected to the mounting frame 5 through a movable spring 14. The inner side wall of the limiting block 13 is fixedly connected to one end of the movable spring 14. When the limiting block 13 moves upward, it will stretch the movable spring 14. When resetting, the elastic force of the movable spring 14 will bring the limiting block 13 back to its original position. The other end of the movable spring 14 is fixedly connected to the top of the mounting frame 5. The limiting block 13 is inserted into the top of the cutting blade 6. The cutting blade 6 has a slot corresponding to the limiting block 13, which can satisfy the one-way limiting of the cutting blade 6 by its insertion.

[0034] Reference Figure 1 - Figure 3 The outer wall of the slider 9 is fixedly connected to one end of the return spring 8. When the slider 9 moves backward, it will compress the return spring 8. When resetting, the elasticity of the return spring 8 will be used to reset the slider 9. The other end of the return spring 8 is fixedly connected to the inner wall of the rear end of the cutting box 1. The slider 9 is slidably connected to the outer wall of the guide rod 10. The top of the wedge block 12 is in contact with the bottom of the L frame 7. The screening frame 11 is slidably connected to the inner wall of the cutting box 1. The inner wall of the cutting box 1 is provided with a feed pipe, which allows the high heat-resistant glass fiber reinforced ABS material to enter the feed pipe and be cut by the cutting blade 6.

[0035] Working principle: When cutting and screening high heat-resistant glass fiber reinforced ABS material particles, simply activate the hydraulic rod 4 to move the mounting frame 5, cutting blade 6, and L-frame 7 downwards. The L-frame 7 then presses the wedge 12, causing the screening frame 11 and slider 9 to move backwards. The slider 9 then presses the return spring 8 to compress the particles. After cutting, the high heat-resistant glass fiber reinforced ABS material particles will fall into the screening frame 11 for screening. Then, the hydraulic rod 4 will move the mounting frame 5, cutting blade 6, and L-frame 7 upwards. When the L-frame 7 is not in contact with the wedge 12, the return spring 8 will use its reverse force to move the slider 9, screening frame 11, and wedge 12 forwards to reset. This ensures that the screening frame 11 moves back and forth during the cutting process, maintaining continuity in the screening process and reducing the risk of clogging.

[0036] When the cutting blade 6 needs to be replaced, simply move the limiting block 13 upward and stretch the movable spring 14 to separate the limiting block 13 from the groove of the cutting blade 6. Then, pull the cutting blade 6 out from the mounting bracket 5 to the right. Finally, release the limiting block 13 and use the reverse elastic force of the movable spring 14 to reset the limiting block 13. When a new cutting blade 6 needs to be installed, simply insert the cutting blade 6 from the right end of the mounting bracket 5, let the left end of the cutting blade 6 press against the inclined surface of the limiting block 13, let the limiting block 13 move upward and stretch the movable spring 14. When the limiting block 13 coincides with the top groove of the cutting blade 6, use the reverse elastic force of the movable spring 14 to reset the limiting block 13, so that the limiting block 13 is inserted into the top of the cutting blade 6. The entire cutting blade 6 can be quickly disassembled and assembled.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
