[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] Specific implementation method one: Combining Figure 1-7 As shown, a conveyor belt for cleaning powder particles includes: a conveyor belt 1, which is divided into left and right conveyor belt structures, and the conveyor belt itself is divided into upper, middle and lower parts. The middle part extends towards the rotary frame 2. The middle part of the conveyor belt 1 has a receiving space 101. The rotary frame 2 is installed in the receiving space 101 through a rotating shaft. A power device for driving the rotary frame 2 to rotate is arranged at the front end of the conveyor belt 1. The rotary frame 2 has four parking slots 201 arranged at 90 degrees to each other. A support 102 is provided in the middle part of the conveyor belt 1. An air jet assembly 3 is installed above the support 102. Limiting components 4 are arranged in pairs in front of and behind the support 102 and can be moved relative to each other. After docking, they complete the covering of the area around the parking slots 201.

[0030] During operation, the parking trough 201 on the left side of the rotary frame 2 remains horizontal. The left conveyor belt carries the packaging bags into the parking trough 201. Then, the power unit drives the rotary frame 2 to rotate 90 degrees, making the packaging belt vertical. After the limiting component 4 docks, it covers the area around the parking trough 201. Then, the air jet component 3 above generates airflow to quickly blow away the dust on the surface of the packaging bags. Under the negative pressure of the limiting component 4, the collection operation is completed. After cleaning, the limiting component 4 quickly resets. At this time, the left conveyor belt also transfers the next packaging bag into the parking trough 201. The power unit drives the rotary frame 2 to rotate 90 degrees again. The cleaned packaging bags contact the right conveyor belt to complete the transfer, which greatly improves the cleaning efficiency and avoids the occurrence of dirt or omissions. Moreover, covering the area around the parking trough 201 can prevent dust from drifting outward and protect the working environment.

[0031] Preferred embodiments, in combination Figure 2 As shown, the parking slot 201 is provided with limiting plates 202 at the front and rear, which can play the role of limiting and guiding the packaging bag.

Guide rods 303 are symmetrically arranged above the carriage 301, and an air chamber 304 is arranged below it. Multiple nozzles 305 are evenly arranged on both sides of the air chamber 304. An air pipe for connecting to an air supply device is located above the air chamber 304. External threads are machined on the area above the guide rods 303. The guide rods 303 pass through the upper part of the bracket 102 to form a sliding connection. A spring 306 is sleeved on the guide rods 303, with the top of the spring 306 contacting the upper part of the bracket 102. The positioning plate 302 is threadedly connected to the upper part of the guide rods 303. During installation, the height of the nozzles 305 can be adjusted by rotating the positioning plate 302, while the spring 306 serves as a positioning support.

[0034] Preferred embodiments, in combination Figure 2As shown, the top of the bracket 102 is equipped with a first hydraulic cylinder 103. The push rod of the first hydraulic cylinder 103 is connected to the slide 301. By adjusting the positioning plate 302 to a suitable position, under normal conditions, the first hydraulic cylinder 103 lifts the slide 301 upward a certain distance and compresses the spring 306. When air needs to be blown, the first hydraulic cylinder 103 is released, and the air chamber 304 moves downward into a certain position inside the parking slot 201. With the help of the limiting component 4, the sealing of the parking slot 201 can be further improved to prevent dust from spreading.

[0035] Preferred embodiments, in combination Figure 3 , Figure 5 and Figure 6 As shown, the limiting component 4 includes a frame 401 and a second hydraulic cylinder 402.

At the same time, the hollow structure is provided with multiple suction ports 403. The frame 401 is provided with a sliding rod 404 that passes through the bracket 102 to achieve positioning support for the frame 401. The second hydraulic cylinder 402 is fixedly connected to the bracket 102, and the push rod is connected to the frame 401. Driven by the second hydraulic cylinder 402, the two frames 401 can be docked. At the same time, negative pressure suction is generated at the suction ports 403, which can collect dust and prevent it from spreading to the external space area, ensuring a clean working environment and meeting the requirements of dust-free production.

[0036] Preferred embodiments, in combination Figure 4 and Figure 6 As shown, the air intake 403 is provided with side intakes 405 on both sides, which can collect the dust that diffuses from the rectangular notch in the middle of the parking slot 201 and improve the extraction efficiency.

[0037] Preferred embodiments, in combination Figure 5 and Figure 6 As shown, splicing channels 406 are symmetrically provided on both sides of the frame 401 to increase the dust diffusion area at the rectangular notch of the parking slot 201 and improve the extraction speed.

[0038] Preferred embodiments, in combination Figure 6 As shown, a fixed bracket 407 is provided in the middle of the frame 401 to connect with the second hydraulic cylinder 402, which facilitates the connection with the second hydraulic cylinder 402 and avoids affecting the installation of the exhaust pipe, making the structural layout more reasonable.

[0039] The power unit is driven by an electric motor. A worm gear is installed at the end of the shaft on the slewing frame 2, and a worm is arranged at the worm gear. The electric motor is connected to the worm through a gear. The slewing frame 2 is rotated by the electric motor and can also be positioned by the worm gear. The structure is stable and reliable. Alternatively, a grooved wheel mechanism can be used to rotate the slewing frame 2 90 degrees each time.
