Description

Sleeve feeding mechanism Technical Field The utility model relates to the technical field of mechanical equipment, in particular to a sleeve feeding mechanism. Background The soft plastic sleeve is widely applied to industries such as electric power, water conservancy and the like, for example, the plastic sleeve can be applied to conveying liquid substances and also can be applied to a coating layer of an electric power cable. The soft plastic sleeve is cut to a fixed length according to different requirements of use scenes. Existing cannula cutting devices mainly comprise two types, namely a mechanical cutting device and a laser cutting device, but whatever type of cutting device requires that the cannula is continuously fed into the cutting device. The existing common feeding device is of a forward pushing type structure, the pushing type structure can only be suitable for the sleeve with a specific caliber, if the caliber of the sleeve is too large or too small, the feeding mechanism can not effectively clamp the sleeve and the feeding is failed, and therefore the design of the feeding mechanism suitable for the sleeve with different calibers is a problem to be considered at present. Disclosure of utility model Based on the expression, the utility model provides a sleeve feeding mechanism to solve the technical problem that the sleeve feeding device in the prior art cannot convey sleeves of different specifications. The technical scheme for solving the technical problems is as follows: The sleeve feeding mechanism comprises a base plate, a first motor, a second motor, a first roller mounting seat, a second roller mounting seat, a first driving roller, a second driving roller, a first driven roller, a second driven roller, a sliding component, a baffle plate and an elastic piece; The first driving roller and the first driven roller are respectively and rotatably arranged on the first roller mounting seat, the second driving roller and the second driven roller are respectively and rotatably arranged on the second roller mounting seat, the sliding component is arranged at the lower end of the base plate, the sliding direction of the sliding component is perpendicular to the feeding direction of the sleeve, the first roller mounting seat is arranged on the sliding component, the second roller mounting seat is fixed at the lower end of the base plate, the first driving roller, the first driven roller, the second driving roller and the second driven roller are distributed above the base plate in a regular quadrilateral shape, a first waist-shaped hole and a second waist-shaped hole which are perpendicular to the feeding direction of the sleeve are formed in the base plate, the first driving roller penetrates through the first waist-shaped hole to be connected with the first roller mounting seat, and the first driven roller penetrates through the second waist-shaped hole to be connected with the first roller mounting seat; The first driving roller is matched with the first driven roller, the second driving roller is matched with the second driven roller, the sleeve is sequentially conveyed forwards through the middle position of the first driven roller and the middle position of the second driven roller and the middle position of the first driving roller and the middle position of the second driving roller, the output end of the first motor is connected with the lower end of the first driving roller, the output end of the second motor is connected with the lower end of the second driving roller, the shell of the first motor is fixedly connected with the first roller mounting seat, the baffle is fixedly connected with the shell of the first motor, one end of the spring is connected with the baffle, the other end of the spring is connected with the shell, the spring is in a compressed state in a normal state, and the first driving roller moves to the limit position close to the first driven roller under the action of the spring.
