Description

Technical Field

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

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity. When using an injection molding machine, a feeding device is required to add raw materials into the machine.

[0003] Current injection molding machine feeding devices, such as the one proposed in publication number CN220841201U, have a stop block and an anti-blocking block that rotate synchronously to agitate the raw material in the connecting pipe, preventing blockage during the material's fall into the connecting pipe and storage hopper, thus ensuring the stability of the injection molding machine's operation and the uniformity and stability of the feeding device.

[0004] While existing injection molding machine feeding devices can ensure the uniformity and stability of material feeding and prevent material blockage, it has been found that the raw materials are prone to moisture absorption during storage. Therefore, drying equipment is needed to dry the raw materials before feeding to prevent them from entering the injection molding machine. Existing feeding devices cannot dry the raw materials during the feeding process, making them inconvenient to use. Therefore, we propose an injection molding machine feeding device to solve the aforementioned problems. Utility Model Content

A hot air blower is installed on the side of the injection molding machine near the hopper. The hot air blower injects high-temperature air into the rotating shaft through the air intake mechanism.

[0015] 1. In this utility model, raw materials flow from the hopper into the injection molding machine. An electric mechanism drives a rotating shaft to rotate, and the rotating shaft agitates the raw materials in the hopper via a stirring rod, causing the raw materials in the hopper to flow and preventing blockage. At the same time, a hot air blower injects high-temperature air into the rotating shaft through an air intake mechanism.

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.

[0022] Example:

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a material feeding device for an injection molding machine, including an injection molding machine 1, a feeding hopper 2 connected to the top of one side of the injection molding machine 1, and a bracket 3 installed on the inner middle of the feeding hopper 2 near the top.

[0024] A rotating shaft 4 is rotatably connected to the middle of the support 3. The rotating shaft 4 is driven to rotate by an electric mechanism. A stirring rod 9 is symmetrically fixed to the outer side of the rotating shaft 4 inside the feeding hopper 2.

[0025] Both the rotating shaft 4 and the stirring rod 9 are hollow structures. The stirring rod 9 has air jet holes 10 equidistantly opened on the ring side. A hot air blower 11 is installed on the side of the injection molding machine 1 near the hopper 2. The hot air blower 11 injects high-temperature air into the rotating shaft 4 through the air intake mechanism.

[0026] Raw materials flow from the hopper 2 into the injection molding machine 1. The electric mechanism drives the rotating shaft 4 to rotate. The rotating shaft 4 agitates the raw materials in the hopper 2 through the stirring rod 9, causing the raw materials in the hopper 2 to flow and preventing blockage. At the same time, the hot air blower 11 injects high-temperature air into the rotating shaft 4 through the air intake mechanism. The high-temperature air is ejected through the jet hole 10 of the stirring rod 9, so that the hot air can come into uniform contact with the raw materials in the hopper 2. The hot air dries the raw materials in the hopper 2, preventing them from becoming damp. This feeding device of the injection molding machine 1 not only prevents blockage during feeding but also dries the raw materials, effectively improving the practicality of the feeding device.

[0027] Please see Figures 1 to 3 The hollow groove inside the rotating shaft 4 is connected to the hollow groove inside the stirring rod 9. The electric mechanism includes a motor 5. The motor 5 is installed on the outer side of the hopper 2 at the height of the bracket 3. The top of the rotating shaft 4 is fixedly connected to a first reversing gear 6. The motor 5 is installed on the shaft end corresponding to the first reversing gear 6. A protective cover 8 is installed on the outer side of the bracket 3 near the first reversing gear 6 and the second reversing gear 7. The first reversing gear 6 and the second reversing gear 7 are perpendicular to each other and mesh with each other. When the motor 5 is working, it drives the second reversing gear 7 to rotate. The second reversing gear 7 drives the first reversing gear 6 to rotate through meshing, so that the first reversing gear 6 drives the rotating shaft 4 to rotate. The rotating shaft 4 is controlled to rotate through this electric mechanism.

[0028] Please see Figures 1 to 3 The air intake mechanism includes a rectangular cover 12. The rectangular cover 12 is installed at the bottom of the bracket 3. A tube groove 13 is formed in the middle of the rectangular cover 12. The rotating shaft 4 passes through the inside of the rectangular cover 12 through the tube groove 13. A sealing ring 14 is installed on the inner wall of the tube groove 13. The hot air blower 11 is connected to the rectangular cover 12 through a connecting pipe 15. An air inlet 16 is opened on the side wall of the rotating shaft 4 inside the rectangular cover 12. The inner wall of the tube groove 13 is sealed to the outside of the rotating shaft 4 through the sealing ring 14. When the hot air blower 11 is working, high-temperature air is injected into the rectangular cover 12 through the connecting pipe 15. When the rotating shaft 4 rotates, the rectangular cover 12 avoids obstructing the rotation of the rotating shaft 4 through the tube groove 13, and seals the connection between the rotating shaft 4 and the rectangular cover 12 through the sealing ring 14. The high-temperature air inside the rectangular cover 12 enters the hollow groove of the rotating shaft 4 through the air inlet 16. Through this air intake mechanism, the hot air blower 11 injects high-temperature air into the hollow groove of the rotating shaft 4.

[0029] Working principle: This injection molding machine feeding device allows raw materials to flow from the feeding hopper 2 into the injection molding machine 1. An electric mechanism drives the rotating shaft 4 to rotate, and the rotating shaft 4 agitates the raw materials in the feeding hopper 2 via the stirring rod 9, ensuring the materials flow smoothly and preventing blockage. Simultaneously, a hot air blower 11 injects high-temperature air into the rotating shaft 4 through the air intake mechanism. The high-temperature air is then ejected through the jet nozzle 10 of the stirring rod 9, allowing the hot air to evenly contact the raw materials in the feeding hopper 2. This hot air dries the raw materials in the feeding hopper 2, preventing them from becoming damp. This feeding device for the injection molding machine 1 not only prevents blockage during feeding but also dries the raw materials, effectively improving the practicality of the feeding device.

[0030] When the motor 5 is working, it drives the second reversing gear 7 to rotate. The second reversing gear 7 drives the first reversing gear 6 to rotate through meshing, so that the first reversing gear 6 drives the rotating shaft 4 to rotate. Through this electric mechanism, the rotation of the rotating shaft 4 can be controlled. When the hot air blower 11 is working, high-temperature air is injected into the rectangular cover 12 through the connecting pipe 15. When the rotating shaft 4 rotates, the rectangular cover 12 avoids obstructing the rotation of the rotating shaft 4 through the pipe groove 13, and seals the connection between the rotating shaft 4 and the rectangular cover 12 through the sealing ring 14. The high-temperature air in the rectangular cover 12 enters the hollow groove of the rotating shaft 4 through the air inlet 16. Through this air intake mechanism, the hot air blower 11 injects high-temperature air into the hollow groove of the rotating shaft 4.
