[0007] A pair of material crushing rollers, with a crushing channel formed between the two rollers, the crushing channel being located below the heating channel;

[0008] The feed plate, with its inlet corresponding to the bottom of the crushing channel, is used to discharge crushed material;

[0009] The power mechanism is used to drive a pair of material block heating rollers and a pair of material block crushing rollers to rotate.

[0010] By adopting the above technical solution, the injection molding edge material crusher of this utility model has the following significant beneficial effects:

[0011] 1. High-efficiency crushing performance: The heating rollers and shredding rollers work together. When the edge material passes through the heating channel, a pair of heating rollers heat and flatten the material, effectively reducing its hardness and toughness. Then, a pair of crushing rollers shear and crush the flat material, ensuring high-efficiency crushing even for thick and hard injection molded edge materials, significantly improving crushing efficiency and quality.

[0012] 2. Durability and energy saving advantages: The material blocks are pre-treated by heating and flattening a pair of material block heating rollers, which facilitates the crushing operation of the material blocks by a pair of material block crushing rollers, thereby effectively reducing crushing energy consumption, reducing wear on the material block crushing rollers, and extending the service life of the equipment.

[0013] 3. Cost Advantage: The machine has significant advantages in waste recycling and processing, improving production efficiency and reducing enterprise costs. Preliminary estimates suggest that this machine can save enterprises approximately 3 million yuan annually in electricity costs, material costs, and environmental treatment expenses.

[0014] A further feature of this invention is that the spacing between the heating channels and the pulverizing channels are both adjustable.

[0015] By further configuring the heating and crushing channels as described above, the system can accommodate injection molding scraps of different sizes and types, improving the versatility and flexibility of the equipment. This adjustable configuration allows the invention to be more widely applied in various injection molding production scenarios, further enhancing crushing efficiency and quality.

[0016] A further feature of this invention is that the two ends of a material block heating roller are supported by a first roller adjuster. The first roller adjuster includes a first roller seat and a first adjusting screw. The first roller seat is slidably connected to the frame and is used to support the ends of the material block heating roller. When the first adjusting screw rotates, it can drive the first roller seat to slide, thereby adjusting the spacing of the heating channels.

[0017] With the further configuration described above, the spacing of the heating channels can be easily adjusted via the first adjusting roller to accommodate injection molding edge materials of different sizes and types.

This adjustment method is not only simple to operate but also has a wide adjustment range, greatly improving the adaptability and flexibility of the equipment.

[0018] A further feature of this invention is that the two ends of one of the material crushing rollers are supported by a second roller adjuster. The second roller adjuster includes a second roller seat and a second adjusting screw. The second roller seat is slidably connected to the frame and is used to support the ends of the material crushing roller. When the second adjusting screw rotates, it can drive the second roller seat to slide, thereby adjusting the spacing of the crushing channel.

[0019] With the further configuration described above, the spacing of the heating channels can be easily adjusted via the first adjusting roller to accommodate injection molding edge materials of different sizes and types. When the first adjusting screw rotates, it drives the first roller seat to slide on the frame, thereby achieving precise adjustment of the heating channel spacing. This adjustment method is not only simple to operate but also has a wide adjustment range, greatly improving the adaptability and flexibility of the equipment.

[0020] A further feature of this invention is as follows: the frame is provided with two supporting walls on the left and right sides. The feeding plate, a pair of material block heating rollers, a pair of material block crushing rollers, and the feeding plate are all installed between the two supporting walls.

The pair of material block crushing rollers are arranged in parallel front to back. The two ends of the front material block crushing roller are supported by a second roller adjuster and are in a rotating fit. The second roller adjuster is set on the corresponding supporting wall. The two ends of the rear material block crushing roller are supported by the two supporting walls and are in a rotating fit.

[0021] By further configuring the above-described structure, this invention achieves efficient recycling and processing of waste materials. A pair of heating rollers uniformly heats and flattens the waste material through precise temperature control, and then a pair of crushing rollers crushes it, ultimately producing fine waste particles. These particles are easy to injection mold, greatly improving the production efficiency and quality of plastic products. Simultaneously, the first and second roller adjusters allow for adjustable positions of the heating and crushing rollers, enabling adjustments based on different waste characteristics or processing requirements, further enhancing the adaptability and flexibility of this invention. Overall, this invention features a compact structure, simple operation, and significant effects, with broad application prospects.

[0022] A further feature of this invention is as follows: each of the two supporting wall panels has a first movable hole and a first mounting hole communicating with the front end of the first movable hole; the first roller seat of the first roller adjuster can be slidably disposed back and forth in the first movable hole; and the first adjusting screw passes through the first mounting hole. Each of the two supporting wall panels also has a second movable hole and a second mounting hole communicating with the front end of the second movable hole; the second roller seat can be slidably disposed back and forth in the second movable hole; and the second adjusting screw passes through the second mounting hole.

[0023] With the above-mentioned further design, the design of the first and second movable holes allows the roller seat to be flexibly adjusted on the support wall, while also ensuring the stability of the roller seat during movement, effectively avoiding the impact of positional displacement on the heating or crushing effect.

[0024] A further feature of this invention is that the power mechanism includes a motor and a transmission gear set, wherein the motor drives a pair of material block heating rollers and a pair of material block crushing rollers to rotate synchronously through the transmission gear set.

[0025] With the above-mentioned further configuration, the motor serves as the power source, and through the precise transmission of the gear set, it ensures that the heating roller and the crushing roller can work in a coordinated manner, thereby improving the overall operating efficiency of the equipment.

[0026] A further feature of this invention is that the frame is equipped with a power switch and a heating switch.

[0039] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] like Figure 1-6 As shown, the present invention discloses an injection molding edge material crusher, comprising a frame 1, wherein the frame 1 is provided with: a feeding plate 2, a pair of material block heating rollers 3, a pair of material block crushing rollers 4, a discharging plate 5, and a power mechanism 6, wherein the feeding plate 2, the pair of material block heating rollers 3, the pair of material block crushing rollers 4, and the discharging plate 5 are arranged sequentially from top to bottom, and the power mechanism 6 is used to drive the pair of material block heating rollers 3 and the pair of material block crushing rollers 4 to rotate;

[0041] The feeding plate 2 is used to receive the material blocks discharged from the injection molding machine. The feeding plate 2 is inclined, with its lower end being the outlet and adjacent to a pair of material block heating rollers 3, so as to guide the plastic edge material to be processed between the pair of material block heating rollers 3.

[0042] A pair of material block heating rollers 3 form a heating channel 31 between them. The heating channel 31 corresponds to the area below the outlet of the loading plate 2. The material block heating rollers are electric heating elements, containing heating wires or heating rods. The spacing of the heating channel 31 (i.e., the roller distance between the pair of material block heating rollers) is adjustable. Specifically, one end of one of the material block heating rollers 3 is supported by a first roller adjuster 7. The first roller adjuster 7 includes a first roller seat 71 and a first adjusting screw 72. The first roller seat 71 is slidably connected to the frame 1 and is used to support the end of the material block heating roller. When the first adjusting screw 72 rotates, it can drive the first roller seat 72 to rotate. The roller seat 71 slides, thereby adjusting the spacing of the heating channels 31. A first handwheel 73 is provided on the first adjusting screw. The first adjusting screw 72 is rotatably connected to the frame 1 and threadedly engaged with the first roller seat. By rotating the first handwheel 73, the first adjusting screw is rotated, which in turn drives the first roller seat 71, which is threadedly engaged with it, to slide, thereby causing the supported material block heating roller 3 to adjust its position (moving closer to or away from another material block heating roller). Of course, the first adjusting screw 72 can also be threadedly connected to the frame 1, and the user can push the first roller seat to slide by rotating the first adjusting screw.

[0043] A pair of material crushing rollers 4 form a crushing channel 41 between them, which corresponds to the area below the heating channel 31. Each material crushing roller 4 has multiple cutter wheels 42 spaced axially along its axis, and these cutter wheels 42 on the pair of material crushing rollers are staggered. The spacing of the crushing channel 41 (i.e., the roller distance between the pair of material crushing rollers) is adjustable. Specifically, both ends of one of the material crushing rollers 4 are supported by a second roller adjuster 8. The second roller adjuster 8 includes a second roller seat 81 and a second adjusting screw 82. The second roller seat 81 is slidably connected to the frame 1 and is used to support the ends of the material crushing roller. When the second adjusting screw 82 rotates, it can drive the second roller seat 81 to slide, thereby adjusting the spacing of the crushing channel 41. A second handwheel is provided on the second adjusting screw. The second adjusting screw is rotatably connected to the frame and threadedly engaged with the second roller seat. By rotating the second handwheel, the second adjusting screw is driven to rotate, which in turn drives the threadedly engaged second roller seat to slide, thereby adjusting the position of the supported material crushing roller (moving closer to or away from another material crushing roller). Of course, the second adjusting screw can also be threadedly connected to the frame, and the user can push the second roller seat to slide by rotating the second adjusting screw.

[0044] The aforementioned adjusting screw can also be driven to rotate by a motor;

[0045] The frame 1 is provided with two supporting wall plates 11 on the left and right. The feeding plate 2, a pair of material block heating rollers 3, a pair of material block crushing rollers 4 and the unloading plate 5 are all installed between the two supporting wall plates 11. The pair of material block heating rollers 3 are arranged in parallel front to back. The two ends of the front material block heating roller 3 are supported by the first roller adjuster 7 and are rotated by bearings. The first roller adjuster 7 is set on the corresponding supporting wall plate 11. The two ends of the rear material block heating roller 3 are supported by the two supporting wall plates 11 and are rotated by bearings. The pair of material block crushing rollers 4 are arranged in parallel front to back. The two ends of the front material block crushing roller 4 are supported by the second roller adjuster 8 and are rotated by bearings. The second roller adjuster 8 is set on the corresponding supporting wall plate 11. The two ends of the rear material block crushing roller 4 are supported by the two supporting wall plates 11 and are rotated by bearings. Both support wall plates 11 have a first movable hole 111 and a first mounting hole 112 communicating with the front end of the first movable hole. The first roller seat 71 of the first roller adjuster 7 can be slidably arranged back and forth in the first movable hole 111. The first adjusting screw 72 passes through the first mounting hole 112. Both support wall plates 11 have a second movable hole 113 and a second mounting hole 114 communicating with the front end of the second movable hole. The second roller seat 81 can be slidably arranged back and forth in the second movable hole 113. The second adjusting screw 82 passes through the second mounting hole 114.

[0046] The feeding plate 5 has its inlet corresponding to the lower part of the crushing channel 41. The feeding plate 5 is inclined, with its higher end serving as the inlet and adjacent to a pair of material crushing rollers 4, so as to receive the crushed edge material falling out of the pair of material crushing rollers 4 and discharge it outward.

[0047] The power mechanism 6 includes a motor 61 and a transmission gear set 62. The motor 61 drives a pair of material block heating rollers 3 and a pair of material block crushing rollers 4 to rotate synchronously through the transmission gear set 62. The motor is installed in the rear space between two support wall plates 11, and the pair of material block heating rollers 3 and the pair of material block crushing rollers 4 are installed in the front space between the two support wall plates 11. A transmission pulley set 63 is set on the outer side of one support wall plate 11, and the transmission gear set 62 is set on the outer side of the other support wall plate 11. The output shaft of the motor 61 is connected to the transmission pulley set 63, and the transmission pulley set 63 and the transmission gear set 62 are directly or indirectly transmitted through a transmission shaft 64. The transmission gear set 62 includes multiple meshing gears, which can synchronously drive the pair of material block heating rollers 3 and the pair of material block crushing rollers to rotate. By setting the size of the gears, the pair of material block heating rollers 3 and the pair of material block crushing rollers can be designed to rotate at the same speed or at different speeds.

[0048] The frame 1 is equipped with a power switch 9 and a heating switch 10. The power switch 9 controls the start and stop of the power mechanism 6 through a circuit control module. The heating switch 10 controls the start and stop of the heating function of a pair of material block heating rollers 3 through a circuit control module. The frame 1 is also equipped with two temperature controllers 20, which independently control the heating temperature of the pair of material block heating rollers 3.

[0049] The working process of this utility model pulverizer is as follows:

[0050] 1. Connect the power supply, turn on the power switch and heating switch, and the power mechanism will drive a pair of material block heating rollers and a pair of material block crushing rollers to start rotating, and the pair of material block heating rollers will start heating;

[0051] 2. The material block injected from the injection molding machine nozzle falls from the upper platen and is heated and flattened by a pair of material block heating rollers;

[0052] 3. The flattened material is shredded by a pair of crushing rollers, breaking it down into smaller particles;

[0053] 4. The fragments fall from the feed plate into the fragment recycling bin for easy collection and utilization later.

[0054] This equipment utilizes a combination of heating rollers and crushing rollers to work together. First, large blocks of material are heated by a pair of heating rollers to prevent them from hardening upon cooling, and simultaneously flattened. They are then fed into a pair of crushing rollers, ultimately yielding crushed pieces. The entire process is highly automated, simple to operate, and significantly improves work efficiency and material utilization. Furthermore, the equipment is equipped with a temperature controller that can independently control the heating temperature of the pair of heating rollers, ensuring uniform heating of the material and improving product quality.
