[0001] This utility model is a mixing device for the production of plastic products, belonging to the field of plastic product technology. Background Technology

[0002] Plastic products are a general term for everyday and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of malleable synthetic polymers, forming, along with synthetic rubber and synthetic fibers, the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins, with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and retain those shapes at room temperature.

[0003] Publication number CN214187928U discloses a mixing device for plastic product processing raw materials. The device involves pouring raw materials into a mixing tank through an inlet, controlling a stirring motor to rotate the agitator, thus mixing the raw materials. Simultaneously, a swing motor is controlled to rotate a swing arm, which in turn swings. Fixed blocks are connected to both the swing arm and the mixing tank, enabling the mixing tank to swing. A first, second, and third side plate are interconnected to further support the mixing tank. However, when mixing plastic products, the mixing tank is only slightly affected by the agitator's operation. When processing large quantities of plastic products, the device requires prolonged operation, resulting in low mixing efficiency. Therefore, a mixing device for plastic product production is urgently needed to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mixing device for the production of plastic products, thereby solving the problems mentioned in the background section. This invention is highly practical. While the mixing drum rotates to mix the plastic products, the mixing paddle rapidly stirs the plastic products in the opposite direction, which increases the mixing efficiency of the plastic products and reduces working time.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mixing device for producing plastic products, comprising a mixing drum and two support frames, wherein a protective cover is fixedly connected to the right end of one of the support frames, a motor is fixedly connected inside the protective cover, a first gear is fixedly connected to the output end of the motor, a second gear is rotatably connected inside the protective cover via a rotating rod, a retaining ring is rotatably connected to the left end of the protective cover, a gear ring is fixedly connected to the right end of the retaining ring, a rotating rod is rotatably connected inside the protective cover, the right end of the second gear rotating rod is connected to the right end of the rotating rod via a belt pulley, the first gear and the gear ring mesh with each other, a stirring rod is fixedly connected to the circumferential surface of the rotating rod, and multiple stirring paddles are fixedly connected to the circumferential surface of the stirring rod.

[0006] Furthermore, an electric push rod is fixedly connected to the circumferential surface of the stirring cylinder, and a sealing plate is fixedly connected to the telescopic end of the electric push rod.

[0007] Furthermore, an observation window is provided on the circumferential surface of the stirring drum, a fixed base plate is fixedly connected to the lower end of the two support frames, and a fixed rib is fixedly connected to the adjacent ends of the two support frames.

[0008] Furthermore, a placement slide box is slidably connected to the upper end of the fixed base plate, and a rubber pad is provided at the lower end of the placement slide box.

[0009] Furthermore, a support ring is fixedly connected to the left end of the stirring cylinder, and the support ring is rotatably connected to the right end of one of the support frames.

[0010] Furthermore, a placement slot is provided at the right end of another support frame, and a sensor is fixedly connected to the inner left wall of the placement slot.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a mixing device for the production of plastic products. Because this utility model adds a mixing drum, a gear ring, a first gear, a second gear, a motor, a rotating rod, a mixing paddle, and a stirring paddle, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. While the mixing drum drives the plastic products to rotate and mix through its own rotation, the stirring paddle will quickly stir the plastic products in the opposite direction, which can increase the mixing efficiency of plastic products and reduce working time.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a mixing device for producing plastic products, including a mixing drum 1 and two support frames 21. A protective cover 5 is fixedly connected to the right end of one of the support frames 21. A motor 13 is fixedly connected inside the protective cover 5. A first gear 14 is fixedly connected to the output end of the motor 13. A second gear 17 is rotatably connected inside the protective cover 5 via a rotating rod. A retaining ring 6 is rotatably connected to the left end of the protective cover 5. A toothed ring 15 is fixedly connected to the right end of the retaining ring 6. A rotating rod 16 is rotatably connected inside the protective cover 5. The right end of the rotating rod of the second gear 17 is connected to the right end of the rotating rod 16 via a belt pulley. The first gear 14 and the toothed ring 15 mesh with each other. A stirring rod 18 is fixedly connected to the circumferential surface of the rotating rod 16. Multiple stirring paddles 19 are fixedly connected to the circumferential surface of the stirring rod 18. This design solves the problem that in the original device, when mixing plastic products, the mixing tank is less affected by the operation of the stirring device, and the equipment needs to run for a long time to mix when processing a large amount of plastic products, resulting in low mixing efficiency.

[0021] As the first embodiment of this utility model: an electric push rod 3 is fixedly connected to the circumferential surface of the mixing drum 1. A sealing plate 4 is fixedly connected to the telescopic end of the electric push rod 3. The electric push rod 3 installed on the mixing drum 1 can drive the sealing plate 4 to move left and right. The sealing plate 4 seals the through hole on the surface of the mixing drum 1, allowing plastic products to be introduced into the mixing drum 1 for mixing. It can also control the electric push rod 3 to discharge the plastic products from the mixing drum 1. An observation window 2 is provided on the circumferential surface of the mixing drum 1. A fixed base plate 7 is fixedly connected to the lower end of the two support frames 21. Fixed ribs 11 are fixedly connected to the adjacent ends of the two support frames 21. The observation window 2 on the surface of the mixing drum 1 allows the user to observe the mixing of the plastic products in the mixing drum 1 from the outside, facilitating the user to control the amount of mixing. The fixed ribs 11 installed at both ends of the support frames 21 can stably support the mixing drum 1 to rotate between the two support frames 21, allowing the mixing drum 1 and the mixing paddle 19 to stably mix the plastic products. A placement slide box 12 is slidably connected to the upper end of the fixed base plate 7. A rubber pad is provided at the lower end of the placement slide box 12. The placement slide box 12 slides within the fixed base plate 7, allowing the user to place a mixing bucket for easy collection of plastic product mixtures. The rubber pad at the bottom of the placement slide box 12 protects its bottom, preventing wear from the ground and thus increasing its service life. A support ring 20 is fixedly connected to the left end of the mixing drum 1. The support ring 20 is rotatably connected to the right end of one of the support frames 21. The support ring 20 on the left end of the mixing drum 1 supports the mixing drum 1 to rotate between the two support frames 21, thereby increasing the stability of the plastic product mixing. Another support frame 21 has a placement slot 9 at its right end. A sensor 8 is fixedly connected to the inner wall of the left side of the placement slot 9. The placement slot 9 on the right side of the support frame 21 can be used to install the sensor 8, which can prevent the electric push rod 3 on the mixing drum 1 from touching the sensor 8. The sensor 8 installed in the placement slot 9 can sense the rotation angle of the mixing drum 1, making it convenient for the user to operate the mixing drum 1.

[0022] As a second embodiment of this utility model: First, the mixing barrel is placed in the placement slide box 12. The electric push rod 3 is controlled to move the sealing plate 4 to the left, so that the through hole on the upper surface of the mixing drum 1 is exposed. Then, the plastic product is introduced into the mixing drum 1. The electric push rod 3 is then controlled to seal the through hole of the mixing drum 1 with the sealing plate 4. The running motor 13 drives the mixing drum 1 to rotate through the gear ring 15. At the same time, the second gear 17 rotates in the opposite direction under the transmission power of the gear ring 15. According to the shape and structure of the gear ring 15 and the second gear 17, the second gear 17 rotates faster and the mixing drum 1 rotates slower. When the mixing drum 1 is rotating, the stirring paddle 19 can quickly mix and stir the plastic product in the opposite direction. Then, the electric push rod 3 is controlled to move downward and the electric push rod 3 drives the sealing plate 4 to retract, so that the plastic product in the mixing drum 1 is discharged through the through hole and introduced into the mixing barrel.
