[0029] In a preferred embodiment, a rectangular hole 4 is provided on the outer surface of the connecting tube 332, and the rectangular hole 4 passes through the interior of the connecting tube 332. A limit plate 34 is slidably connected to the interior of the rectangular hole 4. The limit plate 34 is fixedly installed on the outer surface of the screw rod 32. In order to make the connecting tube 332 rotate with the rotation of the screw rod 32, a rectangular hole 4 is provided on the outer surface of the connecting tube 332. By setting the limit plate 34 on the outer surface of the screw rod 32 inside the rectangular hole 4, the connecting tube 332 can be driven to rotate by rotating the limit plate 34, thereby driving the scraping rod 31 to rotate, which is convenient for scraping the attached raw materials, thereby transporting all the raw materials to the interior of the mold bin 112.
[0030] In a preferred embodiment, a sliding groove 5 is provided on the inner wall of the delivery pipe 311, and a moving block 6 is arranged inside the sliding groove 5. One side of the moving block 6 is fixedly connected to the connecting rod 7, and one end of the connecting rod 7 is fixedly connected to the nut 331. The screw rod 32 is threadedly connected to the nut 331. The device pushes the connecting pipe 332 to move by moving the nut 331, thereby changing the position of the scraping rod 31. In order to move the nut 331, a sliding groove 5 is provided on the inner wall of the delivery pipe 311, and the moving block 6 inside the sliding groove 5 is fixedly connected to the connecting rod 7, and the connecting rod 7 is fixedly connected to the nut 331, so that the nut 331 does not rotate.
[0031] In a preferred embodiment, the top of the conveying pipe 311 is fixedly connected to the feed bin 8, and the interior of the feed bin 8 is connected to the interior of the conveying pipe 311. In order to facilitate the addition of materials to the interior of the conveying pipe 311, the feed bin 8 is fixedly connected to the top of the conveying pipe 311, and the interior of the feed bin 8 is connected to the interior of the conveying pipe 311, thereby facilitating loading and producing products.
[0032] The device controls the rotation of the connecting tube 332, thereby driving the scraper rod 31 to rotate and stirring the attached raw materials. To ensure the stable rotation of the connecting tube 332, an annular groove 9 is opened on one side of the annular plate 33, and a sliding block 10 is arranged inside the annular groove 9. One side of the sliding block 10 is fixedly connected to the connecting tube 332. The connecting tube 332 is sleeved on the outside of the screw rod 32, and a movable sliding block 10 is arranged inside the annular plate 33. The sliding block 10 is fixedly connected to the connecting tube 332, thereby controlling the stable rotation of the connecting tube 332.
[0033] After the circular plate 312 pushes the raw material into the mold bin 112, the circular plate 312 will be controlled to move back. When moving back, some of the raw material will be brought back into the conveying pipe 311, resulting in insufficient raw material for the produced product, which will affect the quality of the product. To solve this problem, an anti-back-suction mechanism 11 is installed inside the conveying pipe 311. The anti-back-suction mechanism 11 includes a magnet 111 and a mold bin 112. The mold bin 112 is fixedly installed at one end of the conveying pipe 311 and is connected to the inside of the conveying pipe 311. The interior of the mold bin 112 is fixedly connected to the positioning frame 12, and one side of the positioning frame 12 is fixedly connected to the magnet 111. The magnet 11 1 is set to two, and are respectively arranged inside the mold bin 112 and inside the conveying pipe 311. The magnetic poles of the two magnets 111 are the same. In actual use, the magnet 111 is installed inside the mold bin 112, and the magnet 111 is also installed inside the conveying pipe 311. The magnetic poles of the two magnets 111 are the same. Therefore, when feeding, the scraper rod 31 pushes it away. When not feeding, the two magnets 111 repel one end of the conveying pipe 311, so that when the circular plate 312 moves back, it is avoided that the raw material is sucked back, thereby ensuring that the raw material can all enter the mold bin 112 and ensure the normal processing of the product.
[0034] Specifically, the working process or working principle of an injection connection device for an injection molding machine is as follows: when the injection molding machine is in use, the raw materials will be added to the interior of the conveying device through the feed bin 8, and the raw materials will be pushed into the mold bin 112 through the pushing device so as to process and shape the raw materials. However, in actual use, since one end of the conveying device is mostly in a conical shape, when the raw materials are pushed, a part of the raw materials will be pressed against the inner wall of the conical end. As the raw materials at this position continue to accumulate, a blockage point will be formed, which will affect the amount of raw materials entering the mold bin 112 later, thereby affecting the processing and molding of the product. Therefore, this device is designed to solve this problem, connect an external power supply, and install the raw materials in the conveying pipe 311 through the feed bin 8. When the amount added to the inside of the conveying pipe 311 is just enough to make a complete product, by turning on the servo motor 321, the screw rod 32 will be controlled to rotate. Since the outer surface of the nut 331 is fixedly connected to the connecting rod 7, the nut 331 will not rotate, and the nut 331 will be controlled to move, so as to push the connecting pipe 332 to move.
[0035] Since a limit plate 34 is provided inside the connecting tube 332, and the limit plate 34 is fixedly connected to the screw rod 32, the connecting tube 332 will be driven to rotate when the screw rod 32 rotates, and the connecting tube 332 will rotate and move at the same time, and the raw material will be pushed inside the conveying tube 311 through the circular plate 312, and the raw material will be conveyed to the inside of the mold bin 112. The corresponding products can be manufactured by using the mold bin 112 in conjunction with the mold bin 2. When the circular plate 312 moves, the scraper rod 31 will be driven to move, and the magnet 111 inside the conveying tube 311 will be pushed to move, so that one end of the magnet 111 is clamped into the space surrounded by the scraper rod 31, and the inside of the conveying tube 311 is opened, so that the raw material can be conveyed into the inside of the mold bin 112, which is convenient for producing products.
[0036] Since one end of the conveying tube 311 is set to a conical shape, some raw materials will accumulate on the inner wall of the conveying tube 311 due to the limitation of the shape. In order to ensure that all the raw materials can be conveyed in, while pushing the circular plate 312 to move, it will drive the scraper rod 31 to rotate continuously and scrape the attached raw materials so that they can be conveyed to the inside of the mold bin 112 together with other raw materials, thereby ensuring the processing effect of the product.
[0037] After the circular plate 312 pushes a batch of raw materials, it will reverse through the servo motor 321, which can drive the screw rod 32 to reverse, thereby driving the connecting tube 332 to move back, and then driving the scraper rod 31 to move back. At this time, the magnet 111 inside the conveying tube 311 will repel the magnet 111 inside the conveying tube 311 under the action of the magnet 111 inside the mold bin 112, and stably install it at the end of the conveying tube 311. Closing one end of the conveying tube 311 can prevent the raw materials from flowing back, ensuring that all the raw materials are moved into the mold bin 112, thereby improving the processing effect of the product.
[0038] It should be noted that the servo motor 321 is a device or equipment existing in the prior art, or a device or equipment that can be implemented in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
