Technical Field
[0001] This utility model relates to the field of automatic belt threading machine technology, and in particular to a belt structure for an automatic belt threading machine. Background Technology
[0002] An automatic strapping machine is a device that automatically feeds strapping or other strip-shaped materials through the object being packaged. Using photoelectric sensors, proximity sensors, and other sensors, it detects the position, shape, and size of the item to be packaged, transmitting signals to the control system. This system then determines the starting position and path for the strapping. The strapping is pulled from the reel and conveyed along a preset path, passing through the object being packaged.
[0003] In existing automatic belt threading machines, one end of the belt extends out of the machine housing and connects to the trolley. However, the length of the belt is usually fixed, which makes it difficult to control the extension distance of the belt and thus difficult to limit the movement of the trolley. To address these issues, we have designed a belt structure for the automatic belt threading machine. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a belt structure for an automatic belt threading machine. The belt body is provided with a limit stop at the tail end. By inserting the stop rod on the belt mounting shell into different stop holes to block the limit stop, the extension distance of the belt can be controlled, thereby limiting the movement of the trolley.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic belt threading machine includes a belt mounting shell and a belt body. The belt mounting shell consists of a belt storage plate and a user-side storage plate. Multiple support columns and spacing stripes are connected inside the belt mounting shell via locking screws, creating an internal storage space. The belt mounting shell houses the belt storage plate, and the belt body is housed within the belt storage plate. Multiple positioning pins are located inside the belt mounting shell. A brake wheel is rotatably connected inside the belt mounting shell, and the brake wheel meshes with the belt body. An opening at the bottom of the belt mounting shell allows the front end of the belt body to pass through. A trolley is connected to the front end of the belt body, and a limit stop is provided at the rear end of the belt body. A limiting component on the belt mounting shell controls the extension distance of the belt body.
[0007] Preferably, the limiting component includes multiple stop holes extending through the user-side storage board, with a stop rod inserted into one of the stop holes to limit the limiting block.
[0008] Preferably, the end of the stop lever located on the outside of the user-side storage board is connected to a plug.
[0009] Preferably, the bottom of the belt mounting housing is connected to a guide shaft by screws, the guide shaft is provided with stress relief grooves, the belt body passes through the guide shaft and exits the opening of the belt mounting housing, and the screws are locked by a serrated locking washer located on the outside of the guide shaft.
[0010] Preferably, the bottom of the belt mounting housing is connected to a guide frame located outside the guide shaft via a self-locking nut.
[0011] Preferably, the user-side storage board is provided with an operation port, and an upper guide rail sliding window and a lower guide rail sliding window are installed in the operation port and fixed by a first fixing screw. The upper guide rail sliding window and the lower guide rail sliding window are jointly installed with a sliding window that is controlled to open and close by a door control switch.

The operation port is provided with a partition plate and an operation board.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] The belt structure of this automatic belt threading machine has a belt body that extends out of the front end of the belt mounting housing and connects to the trolley. The rear end of the belt body, located inside the belt threading machine housing, is equipped with a limit stop. By stably inserting a stop rod into the corresponding stop hole, when the belt body moves and causes the limit stop to abut against the stop rod, the stop rod can restrict the limit stop, preventing the belt body from continuing to move out of the belt mounting housing. This controls the extension distance of the belt body and thus limits the movement of the trolley. Attached Figure Description
