Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, and particularly relates to an adaptive connecting device for a roller cleaning scraper. Background Art

[0002] During the tobacco processing process, materials need to be conveyed through the conveyor belt of the conveying equipment, and the bottom of the conveyor belt is supported by rollers. When dirt accumulates on the rollers, it may affect the smoothness of the conveyor belt or cause the conveyor belt to deviate. The roller scraper can be used to scrape debris on the rollers, thereby ensuring the smoothness of the conveyor belt during conveying and preventing the conveyor belt from deviating. However, the traditional installation method of the scraper is fixed installation. After using for a period of time, due to the wear of the scraper, the gap between it and the roller becomes larger, resulting in a poor cleaning effect on the roller, thus affecting the smooth conveying of the conveyor belt.

[0014] The embodiments of the utility model will be described in detail below. The embodiments are implemented on the premise of the technical solution of the utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the utility model is not limited to the following embodiments.

[0015] See Figure 1 and Figure 2, this embodiment discloses an adaptive idler cleaning scraper connection device. The idler 1 is rotatably installed on the U-shaped conveyor equipment base 2. A scraper 3 is provided on the conveyor equipment base 2. The scraper 3 is installed on the conveyor equipment base 2 through at least two sets of movable connection components 4. Each set of movable connection components 4 includes a movable lining plate 5, a support rod, and an elastic member. The movable lining plate 5 and the support rod are arranged crosswise and obliquely. The bottom end of the movable lining plate 5 is rotatably installed on the conveyor equipment base 2. The top end of the movable lining plate 5 is fixedly installed with the scraper 3 by means of screw connection. A perforation is formed on the movable lining plate 5. The bottom end of the support rod is rotatably installed on the conveyor equipment base 2. The top end of the support rod obliquely penetrates through the perforation of the movable lining plate 5. Elastic members are respectively provided on the support rod at positions on both sides of the movable lining plate 5. The two sides of the movable lining plate 5 are elastically pressed and supported by the elastic members on both sides, so that the blade of the scraper 3 is always in elastic contact with the idler 1.

[0016] Among them, the elastic member adopts a spring 7, the support rod is a lead screw 6. Nuts 8 are respectively threadedly sleeved on the lead screw 6 at positions on both sides of the movable lining plate 5. The elastic member is sleeved on the lead screw 6, and both ends of the elastic member are elastically pressed against the movable lining plate 5 and the nut 8 respectively. A gasket 9 is provided between the nut 8 and the elastic member. The setting of the gasket 9 can ensure stable contact with the elastic member. By adjusting the positions of the two nuts 8 on the lead screw 6, the pre-tightening force of the two springs 7 can be adjusted, so as to adjust the pressure of the two springs 7 on the movable lining plate 5, and further adjust the pressure applied by the scraper 3 to the idler 1.

[0017] The bottom end of the movable lining plate 5 is hinged to the scraper fixing seat 11 of the conveyor equipment base 2 through a first pin shaft 10, so that the movable lining plate 5 can rotate around the first pin shaft 10. The ring at the bottom end of the support rod is hinged to the support seat 13 of the conveyor equipment base 2 through a second pin shaft 12, so that the support rod can rotate around the second pin shaft 12 to meet the elastic support requirements at different angles of the movable lining plate 5. The axes of the first pin shaft 10 and the second pin shaft 12 are both parallel to the axis of the idler 1.

[0018] The adaptive idler 1 cleaning scraper 3 connection device provided by this embodiment elastically presses and supports both sides of the movable lining plate 5 through two elastic members, so that the blade of the scraper 3 is always in elastic contact with the idler 1. Even if the scraper 3 wears after long-term use, the blade of the scraper 3 can still be in elastic contact with the idler 1, thus ensuring the adaptive cleaning of the scraper 3 to the idler 1, ensuring the cleaning effect of the idler 1, and further ensuring the smooth conveying of the conveyor belt.

[0019] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
