[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0017] Example

[0018] See also Figure 1-2 In this embodiment, a packaging machine conveyor belt cleaning device is provided, including a support frame 1, the support frame 1 is used as a frame body, a conveyor belt 2 is installed on it, and a power component 3 is arranged at the end position of one side of the support frame 1. The power component 3 is composed of a motor, a gear and a rotating shaft, etc., which is used as a transmission structure. The power component 3 drives the conveyor belt 2 to rotate on the support frame 1, thereby realizing the function of the conveyor belt 2 to transport materials. The specific structure and installation method of the power component 3 and the conveyor belt 2 are all existing technologies, and no detailed description is given here.

[0019] A cleaning mechanism 4 is arranged at the bottom of the support frame 1 below the conveyor belt 2, and the cleaning mechanism 4 can clean the dust or residual materials on the surface of the conveyor belt 2;

[0020] Specifically, the cleaning mechanism 4 includes a fixed bracket 41, which is installed on the side wall of the support frame 1. A mounting shaft 42 is arranged in the fixed bracket 41, and an arc-shaped cleaning piece 43 is arranged on the mounting shaft 42. The cleaning piece 43 is made of polyurethane material. Polyurethane has physical properties of high strength, high elasticity and high wear resistance, and has good oxidation resistance. Even in a high temperature and humid environment, it can maintain stability and improve the service life of the cleaning piece 43. The top of the cleaning piece 43 contacts the lower surface of the conveyor belt 2, so that during the movement of the conveyor belt 2, it can rub against the cleaning piece 43, thereby cleaning the dust or residual materials on its surface. The conveyor belt 2 of the utility model is used on a packaging machine, so after cleaning, it is beneficial to improve the packaging quality of the product;

[0021] An adjusting bracket 44 is also provided at one end of the mounting shaft 42 close to the fixed bracket 41, and an adjusting rod 45 is installed on the adjusting bracket 44, and an adjusting spring 46 is sleeved on the adjusting rod 45, and an adjusting nut 47 is threadedly connected to the top of the adjusting rod 45 located on the upper side of the adjusting spring 46. When the adjusting nut 47 is screwed, it compresses the adjusting spring 46. After the adjusting spring 46 is compressed, its elastic force increases and is transmitted to the adjusting bracket 44, so that the cleaning sheet 43 can be in elastic contact with the conveyor belt 2. After the cleaning sheet 43 is worn out after long-term use, it can still maintain good contact with the conveyor belt 2.

[0022] The utility model provides a cleaning sheet 43 at the bottom of the conveyor belt 2, and the cleaning sheet 43 is in close contact with the conveyor belt 2. When the conveyor belt 2 rotates, dust is scraped off by the cleaning sheet 43, and the scraped dust slides onto the ground along the cleaning sheet 43. During operation, due to the long-term contact between the cleaning sheet 43 of the polyurethane and the conveyor belt 2, the friction generated will cause the cleaning sheet 43 to wear, and the contact tightness after wear will definitely decrease. In this way, it is necessary to frequently adjust the contact gap by adjusting the bracket 44. In addition, the conveyor belt 2 will also shake when rotating, which will also affect the cleaning effect. Therefore, an adjusting spring 46 extends from the adjusting bracket 44, and the adjusting nut 47 rotates, and the adjusting spring 46 is compressed. The elastic force becomes larger and is transmitted to the cleaning sheet 43 through the adjusting bracket 44, so that the contact between the cleaning sheet 43 of the polyurethane and the conveyor belt 2 has a certain elastic force, which is not a rigid contact. In this way, even if the cleaning sheet 43 is worn, it can still maintain close contact with the conveyor belt 2, so that the cleaning effect remains long-lasting and stable.

[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
