[0028] In this embodiment, the spreading mechanism 7 includes a cylinder 701, the end of the cylinder 701 is fixedly connected to a first rectangular plate 702, the bottom of the first rectangular plate 702 is connected to a second rectangular plate 703 via an opening and closing hinge, and the bottom of the second rectangular plate 703 is designed with a sharp corner. Through the setting of the second rectangular plate 703, the powdered material can be pushed and spread under the push of the cylinder 701 to ensure that the material is heated evenly. The bottom of the second rectangular plate 703 is designed with a sharp corner, which can assist the cleaning mechanism 6 in scraping off some sticky materials on the conveyor platform 1 to increase the cleaning effect.

[0029] In this embodiment, a Velcro 704 is provided on the back side of the first rectangular plate 702, and a wet cleaning cloth 705 is adhered to the surface of the Velcro 704. Through the wet cleaning cloth 705, dirt on the rolling brush 603 will adhere to it, so the rolling brush 603 can be self-cleaned, and after cleaning, it can be torn off the Velcro 704 and replaced.

[0030] In this embodiment, a threaded column 604 is provided at the top center of the connecting frame 601, and a docking port is provided at the end of the telescopic rod 5. The inner wall of the docking port is provided with an internal thread.

[0037] In actual application, the telescopic pull rod 5 is pulled down, the rolling brush 603 contacts the surface of the conveying platform 1, and the motor 602 drives the rolling brush 603 to rotate to clean the conveying platform 1. The second rectangular plate 703 can push the powdered material to spread it under the push of the cylinder 701 to ensure that the material is evenly heated. Its bottom is designed with a sharp angle, which can assist the cleaning mechanism 6 to scrape off some sticky materials on the conveying platform 1 to increase the cleaning effect. Since the bristles of the rolling brush 603 will contact the wet cleaning cloth 705 when it rotates, the dirt on the rolling brush 603 will adhere to it, so the rolling brush 603 can be self-cleaned. After cleaning, it can be torn off the Velcro 704 and replaced. After the equipment is used, the docking jack on the side of the connecting cover 3 is inserted into the docking protrusion on the lower side of the conveying platform 1. At this time, the height of the connecting cover 3 is lowered to cover the conveying platform 1, and then the two sets of dust cover plates 9 are turned out through the hinge to cover the equipment in all directions, which not only blocks dust but also protects the equipment.

[0038] To sum up, with the help of the above-mentioned technical scheme of the utility model, the conveyor platform 1 can be quickly cleaned by setting up the cleaning mechanism 6, and the spreading mechanism 7 can push the powdered material to spread it to ensure that the material is heated evenly. The bottom of the utility model is designed with sharp corners, which can assist the cleaning mechanism 6 to scrape off some sticky materials on the conveyor platform 1 to increase the cleaning effect. After the connecting cover 3 is lowered, it can cover the equipment to prevent dust from falling onto the equipment. When used with the dust cover plates 9 on both sides, the dustproof effect is further improved.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
