Description

Technical Field

[0001] The utility model relates to the technical field of raw material crushers, in particular to a raw material crushing device for the production of heat-dissipating plastic particles. Background Art

[0002] Raw material crushers play a crucial role in modern industry and are widely used in industries such as mining, building materials, chemical engineering, and food. With the progress of technology, the technology of raw material crushers is also constantly developing, integrating more and more intelligent control and automation functions. New crushers use high-strength materials and advanced designs, enhancing the durability and processing capacity of the equipment. With the increasingly strict environmental protection regulations, energy-saving and emission-reducing crushers have gradually become the mainstream of the market, promoting the development of green manufacturing. Raw material crushers will develop towards intelligence, modularization, and high efficiency to meet diverse industrial needs.

[0003] In practical applications, raw material crushers often face some challenges in use. Especially when crushing raw materials at one time, due to the design of the equipment usually being targeted at specific material characteristics, raw materials with larger volumes are likely to cause blockages at the feed inlet during the crushing process. This situation not only interrupts the continuous crushing process of the raw materials but also greatly reduces the production efficiency. After the feed inlet is blocked, the operator needs to stop the machine for cleaning, which not only wastes time but also affects the operating efficiency of the entire production line. Frequent blockages may lead to excessive wear of the equipment, shortening its service life and failing to meet actual requirements. Summary of the Utility Model

[0004] The utility model discloses a raw material crushing device for the production of heat-dissipating plastic particles, aiming to solve the technical problems that raw material crushers often face some challenges in use. Especially when crushing raw materials at one time, due to the design of the equipment usually being targeted at specific material characteristics, raw materials with larger volumes are likely to cause blockages at the feed inlet during the crushing process. This situation not only interrupts the continuous crushing process of the raw materials but also greatly reduces the production efficiency. After the feed inlet is blocked, the operator needs to stop the machine for cleaning, which not only wastes time but also affects the operating efficiency of the entire production line. Frequent blockages may lead to excessive wear of the equipment, shortening its service life.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A raw material crushing device for producing heat-dissipating plastic particles, comprising a housing. A feed box is fixedly connected to the top of the housing. A second rotating shaft is rotatably connected inside the housing. One end of the second rotating shaft is fixedly connected with a first belt pulley. A crushing roller is fixedly connected to the middle position of the second rotating shaft. A motor is fixedly connected to the other end of the second rotating shaft. A third rotating shaft is rotatably connected to the top position of the crushing roller on one side of the housing. One end of the third rotating shaft is fixedly connected with a rotating disc. A second belt pulley is fixedly connected to the other end of the third rotating shaft. A connecting plate is rotatably connected to one side of the rotating disc. A sliding plate is slidably connected to the top of the feed box. One end of the sliding plate is fixedly connected with a pressing block. Two rotating knives are respectively rotatably connected to the other side of the pressing block. Installation grooves are respectively arranged at positions close to the rotating knives on the other side of the pressing block. Two springs are arranged on the inner wall of the installation groove. A fixing plate is fixedly connected to the bottom inner wall of the feed box at a position close to the rotating knife. A fixed knife is fixedly connected to the position on one side of the crushing roller inside the housing. A discharge box is fixedly connected to the other side of the crushing roller inside the housing. Two first rotating shafts are rotatably connected inside the feed box. Conveyor rollers are fixed on the outer surface of the first rotating shafts. A third belt pulley is fixedly connected to one end of the first rotating shaft. A transmission belt is arranged between the first belt pulley, the second belt pulley and the third belt pulley. An arc surface is arranged on one side of the fixing plate.

[0007] As can be seen from the above, a raw material crushing device for producing heat-dissipating plastic particles provided by the present utility model has the following technical effects.

[0008] First: By putting the raw materials for producing heat-dissipating plastic particles into the inside of the feed box, during the rotation of the rotating disc, the sliding plate and the pressing block are driven to slide back and forth through the connecting plate. The raw materials for producing heat-dissipating plastic particles are squeezed through the cooperation of the pressing block and the fixing plate, making the raw materials for producing heat-dissipating plastic particles become flat. The flat raw materials are cut off by the rotating knife and the fixing plate. When the rotating knife touches the arc surface, the spring will be squeezed. The upper rotating knife rotates upward and the lower rotating knife rotates downward, tearing the cut raw materials into small pieces, achieving the effect of preventing the raw materials for producing heat-dissipating plastic particles from being blocked inside the feed box.

[0009] Second: The raw materials torn into small pieces slide downward and contact the crushing roller. During the rotation of the crushing roller, the cutting knives on the crushing roller cooperate with the fixed knife to crush the raw materials torn into small pieces into smaller fragments. Since the cutting knives are spiral-shaped, during the process of cutting the raw materials, the fixed knife can only contact one point on the cutting knife. Due to the small contact area, the shearing pressure between the cutting knife and the fixed knife is greater, achieving the effect of increasing the shearing pressure of the cutting knife.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0017] A raw material crushing device for producing heat-dissipating plastic particles disclosed by the present utility model is mainly applied to the situation where raw material crushers often face some challenges in use. Especially when crushing raw materials at one time, due to the design of the equipment usually being targeted at specific material characteristics, raw materials with a larger volume are likely to cause blockage of the feed inlet during the crushing process. This situation not only interrupts the continuous crushing process of the raw materials, but also greatly reduces the production efficiency. When the feed inlet is blocked, the operator needs to stop the machine for cleaning, which not only wastes time but also affects the operating efficiency of the entire production line. Frequent blockages may lead to excessive wear of the equipment and shorten its service life.

[0018] Refer to Figure 1, Figure 2 , Figure 3 and Figure 4 , a raw material crushing device for producing heat-dissipating plastic particles, comprising a housing 1, a feed box 2 fixedly connected to the top of the housing 1, a second rotating shaft 9 rotatably connected to the inside of the housing 1, a first pulley 8 fixedly connected to one end of the second rotating shaft 9, a crushing roller 14 fixedly connected to the middle position of the second rotating shaft 9, a motor 4 fixedly connected to the other end of the second rotating shaft 9, a third rotating shaft 10 rotatably connected to the top position of the crushing roller 14 on one side of the housing 1, a rotating disc 19 fixedly connected to one end of the third rotating shaft 10, a second pulley 11 fixedly connected to the other end of the third rotating shaft 10, a connecting plate 18 rotatably connected to one side of the rotating disc 19, a sliding plate 16 slidably connected to the top of the feed box 2, an extrusion block 20 fixedly connected to one end of the sliding plate 16, two rotating knives 23 rotatably connected to the other side of the extrusion block 20 respectively, mounting grooves 22 respectively arranged at positions close to the rotating knives 23 on the other side of the extrusion block 20, two springs 21 arranged on the inner wall of the mounting grooves 22, a fixing plate 24 fixedly connected to the bottom inner wall of the feed box 2 at a position close to the rotating knives 23, a fixed knife 15 fixedly connected to the inner side of the housing 1 close to the crushing roller 14, a discharge box 13 fixedly connected to the other side of the housing 1 close to the crushing roller 14, two first rotating shafts 6 rotatably connected to the inside of the feed box 2, conveyor rollers 17 fixed on the outer surface of the first rotating shafts 6, a third pulley 12 fixedly connected to one end of the first rotating shafts 6, a transmission belt 7 arranged between the first pulley 8, the second pulley 11 and the third pulley 12, and an arc surface arranged on one side of the fixing plate 24.

[0019] Specifically, one end of the connecting plate 18 is rotatably connected to the other end of the sliding plate 16.

[0020] In this embodiment, the raw materials for producing heat-dissipating plastic particles are put into the inside of the feed box 2. The motor 4 rotates to drive the second rotating shaft 9, the first pulley 8 and the crushing roller 14 to rotate. The third rotating shaft 10 and the rotating disc 19 are driven to rotate through the transmission belt 7 and the second pulley 11. During the rotation of the rotating disc 19, the sliding plate 16 and the extrusion block 20 are driven to slide back and forth through the connecting plate 18. The raw materials for producing heat-dissipating plastic particles are extruded through the cooperation of the extrusion block 20 and the fixing plate 24, so that the raw materials for producing heat-dissipating plastic particles become flat. The flat raw materials are cut off by the rotating knives 23 and the fixing plate 24. Since an arc surface is arranged on one side of the fixing plate 24, when the rotating knives 23 contact the arc surface, the springs 21 will be compressed. The upper rotating knife 23 rotates upward, and the lower rotating knife 23 rotates downward, tearing the cut raw materials into small pieces, which has the effect of preventing the raw materials for producing heat-dissipating plastic particles from being blocked inside the feed box 2.

[0021] Referring to Figure 1 , Figure 2 andFigure 3 , in a preferred embodiment, the crushing roller 14 rotates inside the discharge box 13, and a plurality of cutting blades are provided on the crushing roller 14, and the shape of the cutting blades is spiral.

[0022] Specifically, there is a distance of five millimeters between the fixed blade 15 and the cutting blade.

[0023] Universal wheels 5 are respectively rotatably connected to the four corners of the bottom of the housing 1, facilitating the movement of the equipment.

[0024] In this embodiment, the shredded raw materials slide downward and come into contact with the crushing roller 14. During the rotation of the crushing roller 14, the cutting blades on the crushing roller 14 cooperate with the fixed blade 15 to crush the shredded raw materials into smaller pieces. Since the cutting blades are spiral, during the process of cutting the raw materials, the fixed blade 15 can only contact one point on the cutting blade. Due to the small contact area, the shearing pressure between the cutting blade and the fixed blade 15 is greater, achieving the effect of increasing the shearing pressure of the cutting blade.

[0025] Furthermore, the conveyor roller 17, the third pulley 12 and the first rotating shaft 6 are driven to rotate by the transmission belt 7. A conveyor belt 3 is arranged between the two conveyor rollers 17. The rotation of the conveyor belt 3 drives the raw materials for producing heat-dissipating plastic particles that have just entered the feeding box 2 to be conveyed downward, achieving the effect of improving the conveying efficiency of the raw materials.

[0026] Working principle: When in use, put the raw materials for producing heat dissipation plastic particles into the interior of the feeding box 2. The motor 4 rotates to drive the second rotating shaft 9, the first pulley 8 and the crushing roller 14 to rotate. The third rotating shaft 10 and the rotating disc 19 are driven to rotate through the transmission belt 7 and the second pulley 11. During the rotation of the rotating disc 19, the sliding plate 16 and the extrusion block 20 are driven to slide back and forth through the connecting plate 18. The raw materials for producing heat dissipation plastic particles are extruded through the cooperation of the extrusion block 20 and the fixed plate 24, making the raw materials for producing heat dissipation plastic particles become flat. The flat raw materials are cut off by the rotating knife 23 and the fixed plate 24. Since there is an arc surface on one side of the fixed plate 24, when the rotating knife 23 contacts the arc surface, the spring 21 will be extruded. The upper rotating knife 23 rotates upward, and the lower rotating knife 23 rotates downward, tearing the cut raw materials into small pieces, which has the effect of preventing the raw materials for producing heat dissipation plastic particles from being blocked inside the feeding box 2. The raw materials torn into small pieces slide downward and contact the crushing roller 14. During the rotation of the crushing roller 14, the cutter on the crushing roller 14 and the fixed knife 15 cooperate to crush the raw materials torn into small pieces into smaller pieces. Since the cutter is spiral-shaped, during the process of cutting the raw materials, the fixed knife 15 can only contact one point on the cutter. Due to the small contact area, the shearing pressure between the cutter and the fixed knife 15 is greater, which has the effect of increasing the shearing pressure of the cutter. The conveyor roller 17, the third pulley 12 and the first rotating shaft 6 are driven to rotate through the transmission belt 7. The rotation of the conveyor belt 3 drives the raw materials for producing heat dissipation plastic particles that have just entered the interior of the feeding box 2 to be conveyed downward, which has the effect of improving the conveying efficiency of the raw materials.

The substitution may be the substitution of some structures, devices, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
