Description

Technical Field

[0001] The utility model relates to the technical field of plate edge banding equipment, in particular to a connection structure between an edge banding machine encoder and a rotating shaft. Background Art

[0002] The board sections of wooden furniture are usually equipped with edge banding to seal the board sections, prevent moisture from damaging the board, and prevent formaldehyde from volatilizing inside the board, while achieving a decorative effect. Nowadays, edge banding machines are generally used to stick edge banding on the sides of the board.

[0003] The edge banding machine in the prior art needs to measure the length of the edge banding tape to achieve the purpose of automatic control or automatic counting. Generally, an encoder is connected to the laminating wheel or the tape feed wheel or other components. In the prior art, the encoder is connected to the rotating shaft of the laminating wheel or the tape feed wheel or other components on which the encoder is installed by a coupling. However, the use of a coupling as an intermediate connecting piece will cause a certain error in the rotation angle between the rotating shaft and the rotating shaft of the encoder, thereby reducing the accuracy of the data measured by the encoder; on the other hand, the coupling has a short service life, which increases the damage rate of the equipment and affects the overall quality of the product. Utility Model Content

[0004] In view of the above problems, the utility model provides a connection structure between an edge banding machine encoder and a rotating shaft, which improves the rotation synchronization between the encoder and the rotating shaft, thereby improving the accuracy of encoder detection data and reducing the maintenance frequency of the equipment.

[0005] The technical solution of the utility model to solve the technical problem is:

[0006] A connection structure between an edge banding machine encoder and a rotating shaft, wherein the rotating shaft is rotatably arranged on a body of the edge banding machine, the rotating shaft of the encoder is coaxially connected to the bottom of the rotating shaft, the main body of the encoder is fixedly connected with a swing plate, a support block is arranged in the rotation direction of the swing plate, the support block is fixedly arranged on the body of the edge banding machine, the support block prevents the swing plate from rotating, a spring is arranged between the support block and the swing plate, and the spring gives elastic force to the swing plate to rotate toward the support block.

[0007] Furthermore, the coaxial connection between the rotating shaft of the encoder and the rotating shaft is a fixed connection or a detachable connection.

[0008] Furthermore, the rotating shaft of the encoder is detachably connected to the rotating shaft, the bottom of the rotating shaft is provided with a blind hole that cooperates with the rotating shaft of the encoder, the side of the rotating shaft is provided with a pressing bolt, the pressing bolt presses the side of the rotating shaft, and the side of the rotating shaft is provided with a plane that cooperates with the pressing bolt.

[0009] Furthermore, the rotating shaft is rotatably mounted on the body of the edge banding machine via a bearing.

[0010] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. One of the above technical solutions has the following advantages or beneficial effects:

[0011] 1. The utility model directly connects the rotating shaft with the rotating shaft of the encoder, thereby improving the rotation synchronization of the rotating shaft and the rotating shaft of the encoder, thereby improving the accuracy of the encoder in detecting the rotation angle of the rotating shaft. In addition, the main body of the encoder is connected through a swing plate, and the support block and the swing plate are limited in one direction, and the other rotation direction is limited by a spring, which solves the problem that the main body of the encoder must have a certain amount of free space for movement due to some reasons, wherein some of the reasons include the rotating shaft driving the encoder to rotate eccentrically during the rotation process due to insufficient coaxiality accuracy between the rotating shaft and the rotating shaft of the encoder. In addition, the present invention eliminates the coupling component, effectively avoiding the problem of high frequency of equipment maintenance due to the short life of the coupling.

[0012] 2. The utility model improves the replaceability of components by detachably connecting the rotating shaft of the encoder, and the components can be disassembled and replaced during maintenance to reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
