[0002] Plastic products are a general term for industrial and household goods made from plastics. Their main component is resin. Because the properties of plastics change when heated, plastics are divided into thermoplastic plastics and thermosetting plastics.

[0003] When recycling waste plastics, they need to be crushed by a crushing device. Most existing crushing devices consist of crushing rollers and a drive unit. The crushing rollers crush the waste plastics. During the crushing process, the plastic is crushed by the upper plastic pressing the lower plastic. However, due to the lack of a downward pressing mechanism, when only a small amount of plastic remains, the crushing rollers are prone to jamming, affecting the recycling efficiency of the equipment. To solve the above problems, a waste plastic recycling device for plastic product manufacturing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a waste plastic recycling device for plastic product manufacturing, which solves the problem that most existing crushing devices consist of a crushing roller and a drive device. The crushing roller crushes the waste plastic. During the crushing process, the plastic is crushed by the plastic above pressing the plastic below. However, because there is no downward pressing mechanism, when only a small amount of plastic remains, the crushing roller is prone to jamming, which affects the recycling efficiency of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a waste plastic recycling device for plastic product manufacturing, comprising a recycling bin.

Crushing rollers 19 are fixedly connected to one surface of both the main gear 9 and the secondary gear 10. Crushing plates 20 are fixedly installed on both sides of the inner wall of the recycling bin 1. A mounting plate 2 is fixedly connected to one side of the recycling bin 1. A vertical rod 3 is fixedly connected to the upper surface of the mounting plate 2. A spring 4 and a slider 18 are installed on the circumferential side of the vertical rod 3. A lifting plate 5 is fixedly connected to one surface of the slider 18. A rack 16 is fixedly connected to one side of the lifting plate 5. A connecting... The frame 6 has a pressure plate 7 fixedly connected to one end. The frame consists of the pressure plate 7, a local gear 15, a rack 16, and a spring 4. The motor 8 drives the main gear 9 to rotate, which meshes with the auxiliary gear 10, causing the two crushing rollers 19 to work together to crush the waste plastic. During crushing, the transmission wheel drives the local gear 15 to rotate. When the local gear 15 meshes with the rack 16, the rack 16 moves the connecting frame 6 downwards, further pressing the pressure plate 7 down on the plastic. At this time, the slider 18 presses down on the spring 4, allowing the crushing rollers 19 to crush the plastic more effectively and preventing jamming. When the local gear 15 is not meshing with the rack 16, the spring 4 resets, and the slider 18 moves the lifting plate 5 upwards, further moving the pressure plate 7 upwards, facilitating continued feeding into the recycling bin 1 and improving the equipment's recycling efficiency.

[0025] A feed inlet is provided on one side of the recycling bin 1, and a feed hopper 14 is fixedly installed inside the feed inlet. A discharge outlet 22 is provided on the bottom surface of the recycling bin 1, and several support columns 17 are fixedly installed on the bottom surface of the recycling bin 1. Guide plates 21 are fixedly installed on both sides of the inner wall of the recycling bin 1.

[0026] The main gear 9, the auxiliary gear 10, the partial gear 15, and the crushing roller 19 are all rotatably connected to the recycling box 1.

[0027] The main gear 9 meshes with the secondary gear 10, and the partial gear 15 meshes with the rack 16.

[0028] The slider 18 is in sliding engagement with the vertical rod 3, and the pressing plate 7 is in sliding engagement with the recycling bin 1.

[0029] The two crushing rollers 19 cooperate with each other, and the crushing rollers 19 cooperate with the crushing plate 20.

[0030] The guide plate 21 is positioned to match the discharge port 22.

[0031] Example:

[0032] like Figures 1-4 As shown, the method of using the waste plastic recycling device for plastic product manufacturing according to this utility model is as follows: When using this utility model, firstly, waste plastic is put into the recycling box 1 through the feeding hopper 14. The motor 8 drives the main gear 9 to rotate. Through the meshing between the main gear 9 and the auxiliary gear 10, the two crushing rollers 19 cooperate to crush the waste plastic. During the crushing process, the transmission wheel drives the partial gear 15 to rotate. When the partial gear 15 meshes with the rack 16, the rack 16 drives the connecting frame 6 to move downward, further causing the pressing plate 7 to press down on the plastic from above, applying pressure to the plastic. At this time, the slider 18 squeezes the spring 4 downward, so that the crushing rollers 19 can better crush the plastic. The crushing process avoids jamming. When the local gear 15 is not engaged with the rack 16, the spring 4 resets, and the slider 18 moves the lifting plate 5 upward, further moving the pressing plate 7 upward, facilitating continued feeding into the recycling box 1 and improving the recycling efficiency of the equipment. The crushed waste plastic falls onto the guide plate 21, which is inclined, allowing the crushed plastic to pass smoothly through the discharge port 22. It should be noted that the crushing roller 19 and the crushing plate 20 are not meshed; there is a certain gap between them. When the plastic passes through the gap between the crushing roller 19 and the crushing plate 20, it will be squeezed and crushed by the two working together.
