[0001] This utility model relates to the field of plastic processing technology, and in particular to a feeding auxiliary mechanism based on a plastic processing injection molding machine. Background Technology
[0002] Plastic processing technology refers to the technical field of processing plastic materials using various methods and equipment to produce various plastic products. It covers the entire process from raw material preparation to final product manufacturing. Plastic processing technology is widely used in many industries such as automobiles, electronics, packaging, daily consumer goods, and medical. In the plastic processing process, the injection molding machine is the key equipment that heats and melts the plastic raw material and injects it into the mold for molding.
[0003] The existing feeding auxiliary mechanisms for plastic injection molding machines often involve complex filter plate replacement processes, making it impossible to change filter plates with different pore sizes according to different production needs. This reduces the adaptability and flexibility of the equipment. In addition, the complex replacement process makes the filter plates prone to clogging after long-term use. Once clogged, it is difficult to clean in time, which leads to the accumulation and waste of raw materials and reduces production efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing feeding auxiliary mechanism based on plastic processing injection molding machine has the disadvantages of complicated filter plate replacement, difficulty in adapting to different production needs, easy clogging, and difficult cleaning, resulting in raw material waste and reduced production efficiency. Therefore, we propose a feeding auxiliary mechanism based on plastic processing injection molding machine.
[0005] To achieve the above objectives, this application adopts the following technical solution: a feeding auxiliary mechanism based on a plastic injection molding machine, comprising a feeding hopper, a plurality of inclined tubes fixed to one side of the feeding hopper, a vertical tube fixed to the other end of the inclined tubes, a discharge hopper fixed to the bottom end of the vertical tube, a rotating shaft rotatably connected inside the feeding hopper, a first motor installed on one side of the feeding hopper, the output end of the first motor fixed to one end of the rotating shaft, a filter plate slidably connected inside the feeding hopper, a fixed shell fixed to the other side of the feeding hopper, a connecting block fixed to one side of the filter plate, a shaped block provided inside the fixed shell, a rotating rod fixed to one side of the shaped block, a circular plate fixed to one end of the rotating rod, a moving plate fixed to the bottom end of the shaped block, an insert block fixed to the bottom end of the moving plate, a slot for cooperating with the insert block provided inside the connecting block, a pull plate slidably connected to the surface of the rotating rod, fixed blocks fixed to both ends of the pull plate, and four fixing holes for cooperating with the fixing blocks provided on one side of the fixed shell.
[0006] Preferably, a first spring is slidably connected to the surface of the rotating rod, one end of the first spring is fixed to the circular plate, and the other end of the first spring is fixed to the pull plate.
[0007] Preferably, two fixing rods are fixed inside the fixed shell, the fixing rods are located on both sides of the irregular block, and the surface of the fixing rods is slidably connected to the inside of the moving plate.
[0008] Preferably, a second spring is slidably connected to the surface of the fixing rod, one end of the second spring is fixed to the inside of the fixing shell, and the other end of the second spring is fixed to the moving plate.
[0009] Preferably, both ends of the filter plate are fixed with sliders, and both ends of the feed hopper are provided with grooves that cooperate with the sliders.
[0010] Preferably, a lead screw is rotatably connected inside the feed hopper, a second motor is installed on one side of the feed hopper, the output end of the second motor is fixed to one end of the lead screw, and a scraper is threaded onto the surface of the lead screw.
[0011] Preferably, guide rods are fixed on both sides inside the feed hopper, and the surface of the guide rods is slidably connected to the inside of the scraper.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, pulling the pull plate outward causes the fixed block to leave the interior of the fixed hole, and pulling the rotating rod causes the irregular block to move away from the connecting block. During this process, the irregular block pulls the moving plate, causing it to move the insert block away from the interior of the slot, thereby disconnecting the connection between the feed hopper and the filter plate.

At the same time, it facilitates the maintenance and cleaning of the filter plates by operators, reducing the accumulation and waste of raw materials caused by filter plate blockage and improving production efficiency.

One side of the fixed shell 8 is provided with fixing holes 18 that cooperate with the fixing blocks 17. There are four fixing holes 18. By pulling the pull plate 16 outward, the fixing blocks 17 are moved away from the interior of the fixing holes 18. The rotating rod 11 is pulled to move the irregular block 10 away from the connecting block 9. During this process, the irregular block 10 pulls the moving plate 13 to move, so that it moves the insert block 14 away from the interior of the slot 15, thereby disconnecting the connection between the feed hopper 1 and the filter plate 7. With the above settings, filter plates 7 with different apertures can be selected according to different production needs, improving the adaptability and flexibility of the equipment, so that it can better meet the diverse production needs. At the same time, it is convenient for operators to maintain and clean the filter plates 7, reduce the accumulation and waste of raw materials caused by the clogging of the filter plates 7, and improve production efficiency.
[0022] Reference Figure 4As shown in this embodiment: a first spring 19 is slidably connected to the surface of the rotating rod 11. One end of the first spring 19 is fixed to the circular plate 12, and the other end of the first spring 19 is fixed to the pull plate 16. By setting the structure of the first spring 19, the pull plate 16 can be quickly pulled to drive the fixing block 17 away from the inside of the fixing hole 18, which is convenient for the next use.
[0023] Reference Figure 5 As shown in this embodiment: two fixing rods 20 are fixed inside the fixed shell 8. The fixing rods 20 are located on both sides of the irregular block 10. The surface of the fixing rods 20 is slidably connected to the inside of the moving plate 13. By setting the structure of the fixing rods 20, the moving path of the moving plate 13 is effectively constrained and deviation is prevented.
[0024] Reference Figure 5 As shown in this embodiment: a second spring 21 is slidably connected to the surface of the fixed rod 20. One end of the second spring 21 is fixed to the inside of the fixed shell 8, and the other end of the second spring 21 is fixed to the moving plate 13. By setting the structure of the second spring 21, after selecting a suitable filter plate 7, the rotating rod 11 is pulled to drive the irregular block 10 to move towards the connecting block 9. At the same time, the rebound force of the second spring 21 is used to push the moving plate 13 to drive the insert block 14 into the interior of the slot 15, thereby realizing the connection between the filter plate 7 and the feed hopper 1. The operation is very simple and reduces labor intensity.

The surface of the guide rods 27 is slidably connected to the inside of the scraper 26. By setting the structure of the guide rods 27, the movement trajectory of the scraper 26 can be restricted, ensuring the consistency of its movement.
[0028] Working principle: By pulling the pull plate 16 outward, the user moves the fixing block 17 away from the fixing hole 18. Pulling the rotating rod 11 moves the shaped block 10 away from the connecting block 9. During this process, the shaped block 10 pulls the moving plate 13, causing it to move the insert block 14 away from the slot 15, thus disconnecting the feed hopper 1 and the filter plate 7. This design allows for the selection of filter plates 7 with different apertures according to different production needs, improving the adaptability and flexibility of the equipment and better meeting diverse production requirements. It also facilitates maintenance and cleaning of the filter plate 7 by operators, reducing material accumulation and waste caused by filter plate 7 blockage and improving production efficiency. The structure of the first spring 19 allows for quick pulling of the pull plate 16 to move the fixing block 17 away from the fixing hole 18, facilitating future use. The structure of the fixing rod 20 effectively... The structure constrains the movement path of the moving plate 13 to prevent deviation. By setting the structure of the second spring 21, after selecting a suitable filter plate 7, the rotating rod 11 is pulled to drive the irregular block 10 to move towards the connecting block 9. At the same time, the rebound force of the second spring 21 is used to push the moving plate 13 to drive the insert block 14 into the interior of the slot 15, thereby realizing the connection between the filter plate 7 and the feed hopper 1. The operation is very simple and reduces labor intensity. By setting the structure of the slider 22 and the slide 23, the stability of the filter plate 7 during movement is ensured and jamming is avoided. By setting the structure of the lead screw 24, the second motor 25 and the scraper 26, the surface of the filter plate 7 can be continuously cleaned to prevent impurities and raw material particles from accumulating on the surface of the filter plate 7, keeping the holes of the filter plate 7 unobstructed and reducing the frequency of filter plate 7 clogging. By setting the structure of the guide rod 27, the movement trajectory of the scraper 26 can be restricted to ensure its consistency during movement.
