Weft feeding automatic adjusting device in ball net machine

Abstract

The invention provides a weft feeding automatic adjusting device in a ball net machine. The device comprises a mesh detection device, a connecting sleeve, an adjusting block, a universal joint, a controller, a rack, a servo motor and a gear, wherein the gear is in transition fit with an output shaft of the servo motor, the gear is meshed with the rack, one end of the rack is connected with the adjusting block through the universal joint, and the adjusting block is installed at one end of a weft feeding moving shaft through a key; the connecting sleeve is arranged on the weft feeding moving shaft in a sleeving mode and is axially fixed, and the connecting sleeve is matched with the adjusting block in a wedge shape; the controller is electrically connected with the servo motor and the mesh detection device separately, the mesh detection device detects the mesh size in real time and transmits signals to the controller, and the controller compares the detected data with set mesh parameters, so that the relative displacement of the adjusting block and the connecting sleeve is controlled, and therefore the weft feeding amount is adjusted. The adjusting device is simple in structure, high in control precision and capable of automatically adjusting the weft feeding amount in the ball net machine, the labor intensity of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a control device, in particular to an automatic adjusting device for weft feeding in a tennis machine. Background technique [0002] Due to the structure problem of self, the net machine produced on the market can only manually detect and adjust the mesh size. Chinese patent No. 98242711.5 discloses a utility model patent for a ball net machine enlarging the mesh control device. Although the device can control the enlarging mesh, there is no automatic detection in the technical solution disclosed in this patent. , Finally, manual detection and manual adjustment are required, so the adjustment ability is limited and cannot meet the needs of automatic mesh size adjustment. During the operation of the netting machine, when the size of the mesh to be knotted changes and is too large or too small compared to the set mesh size, it must be shut down and adjusted manually by the operator, and cannot be adjusted automatically. This pr...

Problems solved by technology

[0002] At present, due to the structural problems of the ball net machine produced on the market, the mesh size can only be manually detected and adjusted.

Chinese patent No. 98242711.5 discloses a utility model patent for a ball net machine enlarging the mesh control device. Although the device can control the enlarging mesh, there is no automatic detection in the technical solution disclosed in this patent. , Finally, manual detection and manual adjustment are required, so the adjustment ability is limited and cannot meet the needs of automatic mesh size adjustment.

This method is relatively simple in terms of mechanical structure, but it is time-consuming and labor-intensive. In particular, the net machine must be suspended to adjust. Therefore, it is necessary to design an automatic adjustment device for weft feeding, so that the amount of weft feeding can be completed during the operation of the net machine. Adjust the size to reduce the labor intensity of the staff and improve work efficiency
