Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and specifically to an injection molding machine feeding device. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, and often referred to as injection molding machines in many factories, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding machines typically consist of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system.

[0003] Existing injection molding machine feeding devices typically require strict control over the amount of plastic raw material added during production to ensure product quality. Furthermore, because various raw materials are added during injection molding, frequent changes in material types are necessary. During this process, residues of other materials may remain on the feeding device, affecting the control of raw material addition and ultimately impacting product quality. Therefore, we propose an injection molding machine feeding device to address the aforementioned problems. Utility Model Content

In addition, since various raw materials need to be added during the injection molding process, the types of raw materials need to be changed frequently. During this process, there may be residues of other raw materials on the feeding device, which will affect the control of raw material addition and affect the final quality of the product.

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.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a feeding device for an injection molding machine, including a drive roller component 1, a driven roller component 2 at one end of the drive roller component 1, a conveyor belt 3 on the outside of the drive roller component 1, a support frame 4 on one side of the driven roller component 2, a rubber scraper component 5 at the end of the driven roller component 2 away from the drive roller component 1, a funnel 6 at the top of the support frame 4 near the end of the drive roller component 1, a cylinder 7 at the other end of the top of the support frame 4, a rotating plate 8 at the other end of the cylinder 7, two movable baffles 9 symmetrically arranged at both ends of the rotating plate 8, and a baffle limiting plate 10 at the bottom of the rotating plate 8.

[0022] The drive roller assembly 1 includes two main roller mounting seats 101, with drive rollers 102 disposed inside the two main roller mounting seats 101. A motor 103 is disposed on one side of each main roller mounting seat 101. The two ends of the drive rollers 102 are rotatably connected to the two main roller mounting seats 101. The motor 103 is fixedly connected to the drive roller mounting seats, and the drive shaft of the motor 103 is fixedly connected to the drive rollers 102. In this example, the motor 103 drives the drive rollers 102 to rotate, thereby driving the conveyor belt 3 to transport plastic raw materials.

[0023] The driven roller component 2 includes two driven roller mounting seats 201, and driven rollers 202 are disposed inside the two driven roller mounting seats 201. The driven roller mounting seats 201 are lower than the main roller mounting seat 101, and the two ends of the driven rollers 202 are rotatably connected to the two driven roller mounting seats 201. In this example, by setting the driven roller mounting seats 201 to be lower than the main roller mounting seat 101, it is convenient for the plastic raw material to slide down and for feeding.

[0024] The conveyor belt 3 is connected to the drive roller 102 and the driven roller 202 at both ends. The rubber scraper component 5 includes two scraper mounting seats 501, and mounting rods 502 are provided inside the two scraper mounting seats 501. The scraper mounting seats 501 are fixedly connected to the two driven roller mounting seats 201 respectively. A rubber scraper 503 is provided on the mounting rod 502. Both ends of the mounting rod 502 are fixedly connected to the two scraper mounting seats 501 respectively. One side of the rubber scraper 503 is fixedly connected to the mounting rod 502, and the other side of the rubber scraper 503 is in close contact with the surface of the conveyor belt 3. In this example, by setting the rubber scraper 503 to be in close contact with the surface of the conveyor belt 3, the residue of plastic raw materials can be cleaned and the amount of feed can be accurately controlled.

[0025] The funnel 6 is fixedly connected to the top of the support frame 4. One end of the cylinder 7 is rotatably connected to the top of the support frame 4, and the other end of the cylinder 7 is rotatably connected to the top of the rotating plate 8. Two waist-shaped grooves 801 are symmetrically arranged on both sides of the rotating plate 8. The rotating plate 8 is rotatably connected to the side of the support frame 4 near the conveyor belt 3. Two sliding grooves 1001 are symmetrically arranged on both sides of the baffle limiting plate 10. The baffle limiting plate 10 is fixedly connected to one side of the support frame 4. In this example, by setting the sliding grooves 1001, the movable baffle 9 can slide smoothly inside the baffle limiting plate 10, thereby controlling the amount of raw materials fed in.

[0026] The top two ends of the movable baffle 9 are slidably connected to the rotating plate 8 via two waist-shaped grooves 801, and the movable baffle 9 is slidably connected to the baffle limiting plate 10 via a sliding groove 1001. In this example, the waist-shaped grooves 801 are provided to facilitate the sliding of the movable baffle 9 inside the rotating plate 8.

[0027] Working principle: Plastic raw materials are placed into the funnel 6 and fall onto the conveyor belt 3. The motor 103 drives the drive roller 102, which in turn drives the conveyor belt 3 to move and transport the plastic raw materials. The conveyor belt 3 drives the driven roller 202 to rotate. During this process, the cylinder 7 drives the rotating plate 8 to rotate, which in turn drives the movable baffles 9 on both sides to slide inside the baffle limiting plate 10 and alternately block the plastic raw materials on the conveyor belt 3, controlling the amount of plastic raw materials fed in. The rubber scraper 503 is in close contact with the conveyor belt 3 and can scrape off the residual plastic raw materials on the conveyor belt 3, avoiding residue from affecting the control of the feeding amount and preventing the accumulation of raw materials from affecting the control of subsequent raw materials.
