AI Technical Summary
The existing unwinding drive mechanism of ribbon looms has a large motor size, which makes it impossible to install more than three parallel warp unwinding drums, increasing the modification cost and the size of the equipment.
The design features a housing that is thicker at the front and wider at the back. The motor output shaft extends to the front of the housing and meshes with a large gear at the end of the warp unwinding drum shaft via a pinion. The worm gear transmission system enables the transmission. The pinion at the front of the housing is placed within the unwinding drum interval, while the motor is located on the outer side at the rear. The controller and housing are located below the motor, and the mounting base is connected to the frame.
Without modifying the warp unwinding drum mounting bracket, a compact installation of more than three warp unwinding drums was achieved, reducing modification costs and minimizing equipment size.

[0002] The loom comprises warp unwinding drums and unwinding transmission mechanisms, each warp unwinding drum is driven by the unwinding transmission mechanism to unwind warp, and the unwound warp enters the weaving mechanism to be woven. Usually, two warp unwinding drums are arranged side by side, and the unwinding transmission mechanism is arranged on the outer side of the warp unwinding drums. When more than three warp unwinding drums are arranged side by side, the distance between adjacent warp unwinding drums is small, and the unwinding transmission mechanism has a large volume (the volume is limited by the size of the motor, and the size of the motor cannot be further reduced to ensure sufficient power), which makes it difficult to install, and the original warp unwinding drum mounting bracket needs to be modified to increase the distance between the warp unwinding drums. This increases the modification cost and increases the overall size of the equipment. SUMMARY

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: the unwinding transmission mechanism of the loom comprises a motor, a pinion and a shell, the motor is provided with a controller, characterized in that: the thickness of the shell is narrow in front and wide in back, a pinion is rotatably arranged on one side of the front part of the shell, the front part of the shell and the pinion can be matched to extend into the space between two adjacent warp unwinding drums of the loom, the pinion is engaged with a large gear on the shaft end of the corresponding warp unwinding drum, and the corresponding shell of the pinion is provided with a worm gear which is coaxially linked with the pinion, a shaft seat for mounting a shaft body, and a worm which is in transmission cooperation with the worm gear, the motor is matched and mounted on the rear part of the shell, the output shaft of the motor extends to the front part of the shell and is in transmission cooperation with the rear end of the worm, and the front end of the shell is provided with a mounting seat which is connected and matched with the rack of the loom.
[0005] The controller is provided with a shell, a control button is arranged on the shell, the shell is connected with the shell, and the thickness of the shell is less than or equal to the thickness of the front part of the shell.

[0007] The mounting seat is provided with a mounting hole, and the mounting hole is arranged on the upper and lower ears of the mounting seat.
[0008] The warp unwinding drums of the loom are arranged in a spaced-apart and side-by-side manner and are more than three in number.
[0009] The unwinding drive mechanism is installed between or on the outside of adjacent warp unwinding drums.
[0010] The beneficial effect of this utility model is that the improved unwinding transmission mechanism of the ribbon loom places the larger motor outside the interval between the two warp unwinding drums by extending the motor output shaft, and places only the front part of the smaller housing and the pinion inside the interval between the warp unwinding drums. In this way, the unwinding transmission mechanism of three or more warp unwinding drums arranged side by side can be installed without modifying the warp unwinding drum mounting bracket, which has substantial features and progress.
