The plastic waste to be recycled can be manufactured into products with specific shapes, functions and performances through various processing techniques and equipment, so that the required plastic products are formed after the injection molded plastic is cooled and solidified, thereby realizing the recycling of plastic waste.

[0003] For example, the patent with publication number CN220331817U discloses a plastic product injection molding machine, including an injection molding machine body and a feed hopper body, an electric telescopic rod is installed on the right side of the top of the injection molding machine body, and a connecting plate is fixed on the top of the output shaft of the electric telescopic rod, a lifting platform is fixed on the left side of the connecting plate, a first motor is fixed on the top of the lifting platform, and the output shaft of the first motor passes through the lifting platform and is bolted to a rotating rod, and the bottom end of the rotating rod is bolted to a mounting frame; when the injection molding machine is idle, the dust on the inner wall of the feed hopper is automatically and effectively cleaned to avoid a large amount of dust accumulation inside the feed hopper, thereby improving the processing quality of the plastic product, and the injection molding machine also has a lifting function, which can lift the plastic raw materials, reduce the labor burden of the staff, facilitate the staff to carry out feeding operations, and provide convenience for the staff.

[0004] For example, the patent with publication number CN218906120U discloses a PP plastic injection molding machine, including a feed barrel, a feed motor installed on the right side of the feed barrel, and a discharge channel installed on the left side of the feed barrel, a feeding mechanism for crushing PP plastic particles is installed above the feed barrel, a sealing mechanism for preventing raw materials from overflowing is installed on the left side of the feed barrel and on the outer surface of the discharge channel, and the feeding mechanism includes a feeding box arranged above the feed barrel; the PP plastic injection molding machine solves the problem that the commonly used injection molding machine adds plastic particles into the inside of the feed barrel for heating and melting and conveying them to the discharge channel when in use, if the plastic particles are large, incomplete melting will occur, thereby affecting the quality of the later products, and at the same time, during the injection process, the sealing between the discharge channel and the pouring port of the mold is not high, resulting in the problem of raw materials overflowing.

[0005] Another example is a patent with publication number CN221540552U that discloses a plastic injection molding machine, including an injection molding machine body, a driving device is installed inside the injection molding machine body, an upper template is installed at the output end of the driving device, a lower template is fixedly connected inside the injection molding machine, an adjustment structure is provided on one side of the upper template, the adjustment structure includes a fixed plate, the fixed plate is fixedly connected to the upper template, a fixed frame is fixedly connected to the side of the fixed plate away from the upper template, and a servo motor is fixedly connected inside the fixed frame; after the injection molding is completed, the plastic product is attached to the upper template, the servo motor is started, the servo motor drives the adjustment disk to rotate, and the adjustment disk uses the adjustment rod to make the adjustment frame move back and forth horizontally, thereby making the two The impact plate repeatedly collides with the upper template, and the vibration generated by the collision causes the plastic product to separate from the upper template, thereby improving the demoulding efficiency and thus improving the production efficiency. When the hot melt liquid in the injection molding machine is injected into the clamping structure, the injection head of the injection molding machine needs to be cleaned first, such as the waste solidified from the previous injection processing that is blocked in the injection head, so as to maintain the smoothness of the injection processing plastic. Some existing injection molding machines are not convenient for mechanically processing the solidified material in the injection head, which is not conducive to the intelligent operation of the injection molding machine. In addition, the solidified material cleaned from the injection head is plastic material, which can be recycled and reused. Some existing injection molding machines do not have the function of autonomously recycling plastic materials, resulting in a certain material waste rate during injection molding.

[0045] Embodiment 2: Based on Embodiment 1, a transmission mechanism is further disclosed, and its specific structure is as follows: a transmission mechanism for recycling plastic waste discharged from the discharge channel 12 is arranged on the processing table 1.

[0046] A slide groove 21 is provided on the inner wall of the material receiving box 17 , a positioning slider 22 is slidably installed in the slide groove 21 , a scraper 23 is fixedly installed on the positioning slider 22 , and a sharp surface of the lower end of the scraper 23 is attached to the inner bottom surface of the material receiving box 17 .

[0047] A hollow column 24 is fixedly installed on the outer surface of the material receiving box 17, and a rotating rod 25 is rotatably connected to the hollow column 24, and a volute spring 27 is elastically connected to the rotating rod 25 and the inner wall of the hollow column 24; a transmission telescopic rod 26 is rotatably connected to the scraper 23, and the telescopic end of the transmission telescopic rod 26 is fixedly connected to the rotating rod 25; a lifting frame 28 is fixedly installed on the sliding bracket 14, and a rack 29 is fixedly installed on the lifting frame 28, and a gear 30 is meshed and connected to the rack 29, and the gear 30 is coaxially fixedly connected to the rotating rod 25.

[0048] A vibrating feeding base 31 is embedded and installed on the bottom surface of the material transfer box 18, and the surface of the vibrating feeding base 31 is inclined; an electric telescopic rod 32 is fixedly installed on the bottom of the processing table 1, and the output end of the electric telescopic rod 32 is fixedly connected to a bottom bracket 33, and a plurality of vibrating cylinders 34 are installed at equal intervals on the bottom bracket 33, and the vibrating cylinders 34 are correspondingly arranged below the vibrating feeding base 31.

[0049] A cylindrical rod 35 is fixedly connected to the bottom of the processing table 1 , and a vibration spring 36 is sleeved on the outside of the cylindrical rod 35 . The vibration spring 36 is elastically connected between the processing table 1 and the bottom bracket 33 .

[0050] The discharge channel 12 moves downward and is engaged with the material receiving box 17, and the plastic waste in the discharge channel 12 enters the material receiving box 17.

The vibration cylinder 34 vibrates up and down to act on the surface of the vibration feeding base 31, keeping the vibration feeding base 31 in a vibrating state, so as to better transfer the plastic waste in the material transfer box 18 to the position of the lifting pipe 19, thereby assisting in completing the recycling of plastics.
