Technical Field
[0001] This invention relates to the field of injection molding technology, specifically to an injection molding device for recycling waste materials from bag production. Background Technology
[0002] In the current luggage manufacturing industry, with increasing environmental awareness and consideration of production costs, the efficient recycling and reuse of waste generated during the production process has become an important trend in industry development.
[0003] In existing technologies, traditional waste recycling methods mostly employ manual sorting and simple crushing followed by remelting. This method is not only inefficient but also labor-intensive. Therefore, it is particularly important to develop a device that can automatically, efficiently, and environmentally friendly process waste materials from bag manufacturing and achieve high-quality injection molding for reuse. To this end, this invention provides a bag manufacturing waste recycling injection molding device. Summary of the Invention
[0004] The purpose of this invention is to provide an injection molding device for recycling waste materials from bag manufacturing, so as to solve the problems mentioned in the background art.
[0005] The technical solution of this invention is: a bag manufacturing waste recycling injection molding device, comprising a mounting base plate, a supporting mounting column fixedly connected to the top of the mounting base plate, a mounting top plate fixedly connected to the top of the supporting mounting column, a fixing side ring fixedly connected to the outer side of the supporting mounting column, an extrusion chamber fixedly connected to the inner side of the fixing side ring, an outer mounting ring fixedly connected to the inner side of the extrusion chamber, a heating bottom ring fixedly connected to the inner side of the extrusion chamber, a guide inclined plate fixedly connected to the top of the heating bottom ring, and an injection port fixedly connected to the top of the outer mounting ring. An extrusion slide post is slidably engaged with the inner side of the outer mounting ring. An extrusion push ball is fixedly connected to the top of the extrusion slide post. An inner mounting ring is fixedly connected to the bottom of the extrusion push ball. A fixing inner ring is fixedly connected to the inside of the outer mounting ring. A protective top ring is fixedly connected to the bottom of the outer mounting ring. An extrusion mesh post is fixedly connected to the top of the heating bottom ring. The extrusion mesh post is fixedly connected to the bottom of the protective top ring. A reset telescopic cylinder is fixedly connected to the bottom of the extrusion push ball. The reset telescopic cylinder is movably fitted onto the outside of the extrusion slide post. The reset telescopic cylinder is fixedly connected to... At the top of the outer ring, a return spring is installed inside the return telescopic cylinder. The return spring is movably sleeved on the outside of the extrusion slide column. A rotary motor is fixedly connected to the top of the mounting top plate. A motor rotating column is fixedly connected to the output end of the rotary motor. An extrusion push ring is fixedly connected to the outside of the motor rotating column, and the extrusion push ring is located at the top of the extrusion push ball. In use: waste material is dropped into the outside of the guide inclined plate through the injection port, and then slides between the two guide inclined plates. Then the rotary motor is started, driving the motor rotating column to rotate, which in turn drives the extrusion push ring to rotate, extruding... The bottom of the extrusion ring has four quarter-sloping surfaces. The extrusion push ball is in close contact with the slope of the extrusion push ring. When the extrusion push ring rotates, it pushes the extrusion push ball downward, compressing the return spring and causing the mounting inner ring to insert between the two guide slopes. The bottom ring is heated to melt the waste material, which is then extruded through the extrusion screen column. The melted plastic enters the bottom of the extrusion chamber for injection molding. When the extrusion push ball passes one of the slopes at the bottom of the extrusion push ring, the return spring rebounds, pushing the extrusion push ball upward, which in turn moves the extrusion slide column and the mounting inner ring upward, thus resetting them.
[0006] Preferably, the bottom of the inner wall of the extrusion chamber is a conical chamber. An extrusion pressure plate is fixedly connected to the outer side of the motor column, and the extrusion pressure plate is in close contact with the conical chamber. A transport inner plate is fixedly connected to the outer side of the support mounting column. Transport column feet are fixedly connected to both ends of the transport inner plate. Transport rollers are fixed to the inner side of the transport column feet. Two transport belts are rotatably connected to the outer side of the transport rollers. An upward push cylinder is fixedly connected to the top of the mounting base plate. An upward push plate is fixedly connected to the top output end of the upward push cylinder. An upper template is connected to the bottom of the extrusion chamber. A lower template is engaged with the top of the transport belt. In use: by engaging the bottom of the lower template with the top of the transport belt, the transport roller drives the transport belt to move, transporting the lower template to the bottom of the upper template. The upward push cylinder is activated, pushing the upper push plate upward, pushing the lower template upward, so that the lower template and the upper template are tightly engaged. The extrusion pressure plate pushes the extrusion, injecting plastic into the interior of the lower template and the upper template. After completion, the upward push cylinder retracts, the lower template moves downward, and transport is carried out for continuous production.
[0007] This invention provides an improved injection molding device for recycling waste materials from bag manufacturing, which has the following improvements and advantages compared to the prior art: Firstly, the bag manufacturing waste recycling injection molding device of the present invention allows waste material to fall through the injection port onto the outside of the guide inclined plate, and then slides between the two guide inclined plates. A rotary motor is then started, driving the motor column to rotate, which in turn drives the extrusion push ring to rotate. The bottom of the extrusion push ring has four quarter-sloping surfaces. The extrusion push ball is in close contact with the slope of the extrusion push ring. When the extrusion push ring rotates, it pushes the extrusion push ball downwards, compressing the return spring and causing the mounting inner ring to insert between the two guide inclined plates. Heating of the bottom ring melts the waste material, which is then extruded through the extrusion screen column. The melted plastic enters the bottom of the extrusion chamber for injection molding. When the extrusion push ball passes one slope at the bottom of the extrusion push ring, the return spring rebounds, pushing the extrusion push ball upwards, which in turn moves the extrusion slide column and the mounting inner ring upwards, thus resetting them. Secondly, the bag manufacturing waste recycling injection molding device of the present invention, by clamping the bottom of the lower mold plate to the top of the conveyor belt, moves the conveyor belt through the conveyor roller, so that the lower mold plate is transported to the bottom of the upper mold plate. The upper push cylinder is activated, pushing the upper push plate to move upward, pushing the lower mold plate to move upward, so that the lower mold plate and the upper mold plate are tightly locked together. The extrusion plate pushes the extrusion, so that the plastic is injected into the interior of the lower mold plate and the upper mold plate. After completion, the upper push cylinder retracts, the lower mold plate moves downward, and the transportation is carried out for continuous production. In summary, the bag manufacturing waste recycling and injection molding device described in this invention achieves multiple goals of automation, high efficiency, and environmental protection by optimizing the waste recycling and injection molding process. Its unique structural design not only improves the efficiency of waste treatment but also significantly reduces labor intensity, effectively solving the problems of low efficiency and high labor intensity in traditional waste recycling methods.

[0010] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0011] This invention provides an improved injection molding device for recycling waste materials from bag manufacturing. The technical solution of this invention is as follows: like Figures 1-7As shown, a bag manufacturing waste recycling injection molding device includes a mounting base plate 1, a supporting mounting column 2 fixedly connected to the top of the mounting base plate 1, a mounting top plate 3 fixedly connected to the top of the supporting mounting column 2, a fixing side ring 5 fixedly connected to the outer side of the supporting mounting column 2, an extrusion chamber 11 fixedly connected to the inner side of the fixing side ring 5, an outer mounting ring 13 fixedly connected to the inner side of the extrusion chamber 11, a heating bottom ring 14 fixedly connected to the inner side of the extrusion chamber 11, a guide inclined plate 15 fixedly connected to the top of the heating bottom ring 14, an injection port 16 fixedly connected to the top of the outer mounting ring 13, and an extrusion slide plate 16 slidably engaged on the inner side of the outer mounting ring 13. The top of the extrusion slide column 17 is fixedly connected to an extrusion pusher ball 18. The bottom of the extrusion pusher ball 18 is fixedly connected to an inner mounting ring 22. The inner mounting ring 13 is fixedly connected to a fixing inner ring 29. The bottom of the outer mounting ring 13 is fixedly connected to a protective top ring 26. The top of the heating bottom ring 14 is fixedly connected to an extrusion mesh column 25. The extrusion mesh column 25 is fixedly connected to the bottom of the protective top ring 26. The bottom of the extrusion pusher ball 18 is fixedly connected to a reset telescopic cylinder 23. The reset telescopic cylinder 23 is movably fitted onto the outside of the extrusion slide column 17. The reset telescopic cylinder 23 is fixedly connected to the top of the outer mounting ring 13. An internal return spring 24 is installed, which is movably sleeved on the outside of the extrusion slide column 17. A rotary motor 4 is fixedly connected to the top of the mounting plate 3. A motor rotating column 19 is fixedly connected to the output end of the rotary motor 4. An extrusion push ring 20 is fixedly connected to the outside of the motor rotating column 19. The extrusion push ring 20 is located on top of the extrusion push ball 18. In use: the waste material falls into the outside of the guide inclined plate 15 through the injection port 16, and then slides between the two guide inclined plates 15. Then the rotary motor 4 starts, driving the motor rotating column 19 to rotate, driving the extrusion push ring 20 to rotate. The bottom of the extrusion push ring 20 has four quarter-sized parts. The extrusion push ball 18 is pressed against the inclined surface of the extrusion push ring 20. When the extrusion push ring 20 rotates, it pushes the extrusion push ball 18 downward, compressing the return spring 24 and causing the mounting inner ring 22 to insert between the two guide inclined plates 15. The waste material is melted by heating the bottom ring 14, and the melted waste material is extruded through the extrusion mesh column 25. The melted plastic enters the bottom of the extrusion chamber 11 for injection molding. When the extrusion push ball 18 passes over one inclined surface at the bottom of the extrusion push ring 20, the return spring 24 rebounds, pushing the extrusion push ball 18 upward, which in turn drives the extrusion slide column 17 and the mounting inner ring 22 upward, thus resetting them.
[0012] Furthermore, the bottom of the inner wall of the extrusion chamber 11 is a conical chamber. An extrusion pressure plate 21 is fixedly connected to the outer side of the motor rotating column 19, and the extrusion pressure plate 21 is in close contact with the conical chamber. A transport inner plate 7 is fixedly connected to the outer side of the support mounting column 2. Transport column feet 6 are fixedly connected to both ends of the transport inner plate 7. A transport roller 27 is fixed to the inner side of the transport column feet 6. Two transport belts 8 are rotatably connected to the outer side of the transport roller 27. An upward pushing cylinder 9 is fixedly connected to the top of the mounting base plate 1. An upward pushing plate 10 is fixedly connected to the top output end of the upward pushing cylinder 9. The bottom of the extrusion chamber 11 is connected to the upper template 12. The top of the conveyor belt 8 is fitted with a lower template 28. In use: by attaching the bottom of the lower template 28 to the top of the conveyor belt 8, the conveyor belt 8 is moved by the conveyor roller 27, so that the lower template 28 is transported to the bottom of the upper template 12. The upper push cylinder 9 is activated, pushing the upper push plate 10 upward, which in turn pushes the lower template 28 upward, so that the lower template 28 and the upper template 12 are tightly fitted together. The extrusion plate 21 pushes the extrusion, so that the plastic is injected into the interior of the lower template 28 and the upper template 12. After completion, the upper push cylinder 9 retracts, the lower template 28 moves downward, and the conveyor belt is transported for continuous production.
[0013] Working principle: During use: Waste material falls through the injection port 16 onto the outside of the guide ramp 15, then slides between the two guide ramps 15. The rotary motor 4 then starts, driving the motor column 19 to rotate, which in turn drives the extrusion push ring 20 to rotate. The bottom of the extrusion push ring 20 has four quarter-sloping surfaces. The extrusion push ball 18 is in close contact with the slope of the extrusion push ring 20. When the extrusion push ring 20 rotates, it pushes the extrusion push ball 18 downwards, squeezing the return spring 24, causing the inner mounting ring 22 to insert between the two guide ramps 15. Heating by the heating bottom ring 14 melts the waste material, which is then extruded through the extrusion mesh column 25. The melted plastic enters the bottom of the extrusion chamber 11 for injection molding. When the extrusion push ball 18... When the extrusion pusher ring 20 passes through a slope at its bottom, the return spring 24 rebounds, pushing the extrusion pusher ball 18 upward, which in turn moves the extrusion slide column 17 and the mounting inner ring 22 upward, thus resetting them. By locking the bottom of the lower template 28 onto the top of the conveyor belt 8, the conveyor roller 27 drives the conveyor belt 8 to move, transporting the lower template 28 to the bottom of the upper template 12. The upward pusher cylinder 9 is activated, pushing the upper pusher plate 10 upward, which in turn pushes the lower template 28 upward, so that the lower template 28 and the upper template 12 are tightly engaged. The extrusion plate 21 pushes the extrusion, injecting plastic into the interior of the lower template 28 and the upper template 12. After completion, the upward pusher cylinder 9 retracts, the lower template 28 moves downward, and transportation continues for continuous production.
