Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically to a waste recycling mechanism for injection molds. Background Technology

[0002] With the booming development of the injection molding industry, the amount of waste generated during the injection mold production process is increasing day by day. As a by-product of the production process, although these wastes no longer have the complete function of the original products, they still contain considerable residual value. Through professional recycling technology, the plastic components in the wastes can be transformed back into renewable resources, which not only conforms to the sustainable development concept of resource recycling, but also reduces the raw material procurement costs for enterprises. At the same time, the construction of a waste recycling system helps to reduce the pressure of solid waste on the environment, promotes the industry's transformation towards green manufacturing, and achieves a synergistic improvement in economic and ecological benefits.

[0003] Injection mold waste recycling facilities generate a lot of fine dust and debris during the crushing of waste materials. However, existing recycling facilities generally lack the ability to separate the waste materials from the generated dust and debris. During the discharge process, these fine dust particles are discharged along with the normal waste materials. Workers in such an environment are easily exposed to these particles, which can damage the respiratory system and cause respiratory diseases over time, affecting their health. Furthermore, the waste mixed with these particles will have higher impurity levels during subsequent processing, affecting the quality and performance of recycled products and significantly reducing the recycling efficiency. Therefore, we propose an injection mold waste recycling facility. Utility Model Content

[0004] The purpose of this invention is to provide a waste recycling mechanism for injection molds, addressing the problem that existing recycling mechanisms generally lack the function of separating waste materials from the generated fine dust and debris. During the discharge stage, these fine dust particles are discharged along with normal waste. Workers in such an environment are easily exposed to these particles, which can damage the respiratory system and cause respiratory diseases with prolonged exposure, affecting their health. Furthermore, this waste mixed with dust particles will have higher impurity levels during subsequent processing, affecting the quality and performance of recycled products and significantly reducing the recycling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste injection mold recycling mechanism, comprising a processing box, two crushing rollers arranged near the top of the processing box, motors fixedly installed on the front surface of the processing box corresponding to the front ends of the two crushing rollers, a sieve plate arranged near the bottom of the processing box, a screen fixedly installed on the top of the sieve plate, a vibrator fixedly installed at the center of the bottom of the sieve plate, support columns arranged at the four corners of the lower end of the sieve plate, springs fixedly connected to the bottom of the support columns, and connecting columns fixedly connected to the top of the springs, a collection box arranged on one side of the processing box, a fan fixedly installed at the center of the top of the collection box, an isolation mesh plate fixedly installed at the bottom of the collection box corresponding to the fan, a suction hood fixedly installed near the bottom of one side of the processing box, a suction pipe connected to one end of the suction hood, a feed hopper fixedly connected to the center of the top of the processing box, and a discharge pipe fixedly connected to the bottom of the other side of the processing box.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This injection mold waste recycling mechanism, through the design of a sieve plate, sieve mesh, vibrator, support column, spring, connecting column, collection box, isolation mesh plate, fan, suction pipe, and suction hood, allows waste materials to fall onto the sieve plate after being crushed by the crushing roller. At this time, the fan and vibrator are turned on to make the sieve plate vibrate. Since the sieve plate is set at an incline, the crushed waste materials are shaken off and discharged through the discharge pipe. Some fine fragments and dust pass through the sieve mesh through vibration, and at the same time, the suction force generated by the fan draws the fragments and dust into the collection box, preventing fragments and dust from mixing with qualified waste materials. This greatly improves the quality and purity of the recycled waste materials, ensures the stable performance of the recycled products, and significantly improves the working environment, reduces the risk of workers inhaling harmful dust, and effectively protects the health of the workers.

Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a waste recycling mechanism for injection molds, comprising a processing box 1, characterized in that: two crushing rollers 2 are arranged at the top position inside the processing box 1, motors 3 are fixedly installed on the front surface of the processing box 1 corresponding to the front ends of the two crushing rollers 2, a sieve plate 6 is arranged at the bottom position inside the processing box 1, a screen 7 is fixedly installed on the top of the sieve plate 6, a vibrator 8 is fixedly installed at the center of the bottom of the sieve plate 6, support columns 9 are arranged at the four corners of the lower end of the sieve plate 6, springs 10 are fixedly connected to the bottom of the support columns 9, and connecting columns 11 are fixedly connected to the top of the springs 10, a collection box 14 is arranged on one side of the processing box 1, a fan 16 is fixedly installed at the center of the top of the collection box 14, an isolation mesh plate 15 is fixedly installed inside the collection box 14 corresponding to the bottom of the fan 16, a suction hood 18 is fixedly installed at the bottom position on one side of the processing box 1, a suction pipe 17 is connected to one end of the suction hood 18, a feed hopper 20 is fixedly connected to the center of the top of the processing box 1, and a discharge pipe 21 is fixedly connected to the bottom of the other side of the processing box 1.

[0015] The crushing teeth fixedly installed on the surfaces of the two crushing rollers 2 are set to mesh with each other. The motor 3 is fixedly connected to the output shaft through the output end of its rear surface. The rear ends of the two output shafts pass through the interior of the processing box 1 and are fixedly connected to the center of the front surface of the two crushing rollers 2 respectively. When the motor 3 drives the output shaft to rotate the two crushing rollers 2, the input injection mold waste can be efficiently and thoroughly crushed.

[0016] Both sides of the top of the processing box 1 are fixedly installed with first guide plates 4. The two first guide plates 4 are symmetrically inclined. The inner wall of the processing box 1 is fixedly installed with a second guide plate 5 corresponding to the lower end of the right crushing roller 2. The second guide plate 5 is inclined. When the waste is poured into the processing box 1, the two first guide plates 4 will guide the waste into the space between the two crushing rollers 2. At the same time, after crushing, the second guide plate 5 will guide the waste to slide down to one side of the screen plate 6, thereby improving the screening efficiency.

[0017] The tops of the four connecting columns 11 extend through to the outside of the four support columns 9 and are fixedly connected to the bottom of the screen plate 6. The bottoms of the four support columns 9 on both sides are fixedly connected to support plates. The opposite sides of the four support plates on both sides are fixedly connected to the inner wall of the processing box 1, so that the screen plate 6 has a certain buffering effect when vibrating.

[0018] The top of both sides of the support column 9 is provided with a sliding groove 12, and the bottom of both sides of the connecting column 11 is fixedly connected with a slider 13. The opposite sides of the two sliders 13 extend into the interior of the two sliding grooves 12 and slide in connection with the inner wall of the sliding grooves 12, thus ensuring the stability of the connecting column 11 when it moves up and down due to vibration.

[0019] One side of the suction hood 18 extends into the interior of the processing box 1. One end of the suction pipe 17 is fixedly connected to the bottom side of the collection box 14. A door is movably installed on the bottom side of the front surface of the collection box 14. Under the action of the fan 16, the fine waste particles at the bottom of the processing box 1 will enter the suction pipe 17 through the suction hood 18 and finally be drawn into the collection box 14. Users can clean the dust and debris collected in the collection box 14 by opening the door.

[0020] Both the sieve plate 6 and the discharge pipe 21 are inclined structures. One side of the sieve plate 6 extends to the outside of the discharge pipe 21. Through vibration, the crushed waste material is easily shaken off into the discharge pipe 21.

[0021] A base plate 19 is fixedly installed at the bottom of the processing box 1 and the collection box 14.

[0022] During operation, the injection mold waste recycling mechanism first feeds the waste material through the feed hopper 20 at the top center of the processing box 1. Once inside the processing box 1, the first guide plates 4, symmetrically inclined on both sides of the top, guide the waste material accurately between two interlocking crushing rollers 2. The motor 3 starts, driving the two crushing rollers 2 to rotate synchronously in opposite directions via its output shaft. The crushing teeth on the surface of the crushing rollers 2 work together to efficiently and thoroughly crush the waste material, breaking large pieces of injection mold waste into smaller particles. The crushed waste material then disintegrates under its own weight and... Under the inclined guiding action of the second guide plate 5, the material slides down to one side of the screen plate 6. The vibrator 8 at the bottom center of the screen plate 6 starts to work and generates vibration. At this time, the springs 10 at the bottom of the four support columns 9 cooperate with the connecting columns 11 to provide buffering and support for the vibration of the screen plate 6. At the same time, the sliding grooves 12 opened at the top of both sides of the support columns 9 are slidably connected with the sliders 13 fixed at the bottom of both sides of the connecting columns 11, ensuring the stability of the screen plate 6 during vibration and enabling it to perform vibration screening smoothly and effectively. Because the screen plate 6 is set with an inclined structure, under the action of the vibrator 8, Qualified waste particles that meet the particle size requirements will pass through the screen 7 and gradually roll down the inclined screen plate 6 to the discharge pipe 21, and finally be discharged from the treatment box 1 through the discharge pipe 21 for subsequent recycling. Some fine debris and dust will remain on the screen plate 6. With the continuous vibration of the screen plate 6, some of these debris and dust will further pass through the screen 7 and fall to the bottom of the treatment box 1. At the same time, the fan 16 installed at the top center of the collection box 14 starts to operate, generating negative pressure in the collection box 14. The suction hood installed on one side of the treatment box 1 near the bottom starts to operate. One side of the suction hood 18 extends into the interior of the treatment box 1. Under negative pressure, fine dust particles at the bottom of the treatment box 1 are sucked into the suction pipe 17 through the suction hood 18 and enter the collection box 14 along the suction pipe 17. The isolation mesh plate 15 installed inside the collection box 14 corresponding to the bottom of the fan 16 can effectively block dust particles from entering the fan 16 and protect the safe operation of the fan 16. When the dust particles collected in the collection box 14 accumulate to a certain level, the staff can clean the collected dust particles by opening the door installed at the bottom of the front surface of the collection box 14.

[0023] In summary, this injection mold waste recycling mechanism, through the design of screen plate 6, screen 7, vibrator 8, support column 9, spring 10, connecting column 11, collection box 14, isolation screen plate 15, fan 16, suction pipe 17, and suction hood 18, allows waste materials to be crushed by crushing roller 2 and fall onto screen plate 6. At this time, the fan 16 and vibrator 8 are turned on to make screen plate 6 vibrate. Since screen plate 6 is inclined, the crushed waste materials will fall into discharge pipe 21 and be discharged. Some fine fragments and dust pass through screen 7 through vibration, and at the same time, the suction force generated by the fan 16 sucks the fragments and dust into collection box 14, avoiding the mixing of fragments and dust with qualified waste materials. This greatly improves the quality and purity of recycled waste materials, ensures the stable performance of recycled products, and greatly improves the working environment, reduces the risk of workers inhaling harmful dust, and effectively protects the health of workers.
