DETAILED DESCRIPTION

[0017] Reference Figs. 1 to 3 Further illustrate the embodiments of the utility model.

[0018] A brush 1 device for a computerized flat knitting machine, comprising a head 100, the head 100 is connected with a brush unit 200 and an adjusting part 300, the brush unit 200 comprises a brush 1, a mounting plate 2, a spring 3 and two sliding blocks 4, one end of the adjusting part 300 is connected to the head 100, the other end of the adjusting part 300 is connected to the upper surface of the mounting plate 2, the lower surface of the mounting plate 2 is provided with a sliding groove 5 which is slidably connected with the two sliding blocks 4, the sliding block 4 is clamped with the sliding groove 5, the spring 3 is connected with the two sliding blocks 4 at both ends, and the spring 3 is in a compressed state, the brush 1 is arranged on the lower surface of the mounting plate 2, and the brush 1 is connected with two connecting pieces 6 corresponding to the two sliding blocks 4, the connecting piece 6 is provided with a limiting hole 7 matched with the sliding block 4, the sliding block 4 is connected with a plug-in rod 18 inserted into the limiting hole 7, the plug-in rod 18 is screwed with a nut 19, the mounting plate 2 is provided with two stop grooves 20 corresponding to the two sliding blocks, the two stop grooves 20 are communicated with the sliding groove 5, and the stop groove 20 is connected with a stop plate 21, the stop plate 21 passes through the stop groove 20 and extends into the sliding groove 5 and abuts against the sliding block, and the stop plate 21 is L-shaped and is installed on the mounting plate 2 by screws.

[0019] When the computerized flat knitting machine works, the brush 1 is damaged during use, the damaged brush 1 becomes lighter in weight and the bristles thereon become shorter, the adjusting part 300 is used to lower the brush 1 so that the brush 1 can continue to be used to open the latch of the knitting needle.

[0020] When the brush 1 is damaged to the extent that it cannot be used any more and needs to be replaced by a new brush 1, the screw cap 19 is rotated to be separated from the insertion rod 18, the two sliding blocks are smoothly slid in the sliding groove 5 by applying force to the two sliding blocks to compress the spring 3, and the two sliding blocks are close to each other, so that the insertion rod 18 on the sliding block is separated from the limiting hole 7 of the connecting piece 6 on the old brush 1 to achieve the purpose of disassembling the old brush 1, and then the insertion rod 18 on the sliding block is inserted into the limiting hole 7 of the connecting piece 6 on the new brush 1 to achieve the installation of the new brush 1. The insertion rod 18 is a threaded screw rod, and the screw cap 19 is installed on the insertion rod 18 to prevent the insertion rod 18 from being separated from the limiting hole 7 when the brush 1 is in use, which affects the use of the brush 1. At this time, the spring 3 returns to its original state to make the two sliding blocks respectively abut against the corresponding stop plates 21. Without external force, the sliding blocks are stably connected in the sliding groove 5, the new brush 1 is stably installed, the old brush 1 is easily disassembled and the new brush 1 is easily installed, the operation of disassembling the old brush 1 and installing the new brush 1 is convenient, the damaged brush 1 can be quickly and timely replaced, the difficulty of replacing the new brush 1 is reduced, and professional operation is not required.

[0021] The adjusting part 300 includes a fixed column 8, a movable rod 9, a controller 10, a gravity sensor 11 and a gas cylinder 12. One end of the fixed column 8 is installed on the machine head 100, and the other end of the fixed column 8 is provided with a movable groove 13 matched with the movable rod 9. One end of the movable rod 9 is movably arranged in the movable groove 13. The controller 10 is installed on the fixed column 8 and electrically connected with the gravity sensor 11. The gravity sensor 11 is installed on the other end of the movable rod 9 and connected with the installation plate 2. The gas cylinder 12 is installed on the top of the fixed column 8 and electrically connected with the controller 10. The output end of the gas cylinder 12 extends into the movable groove 13 through the fixed column 8 and is connected with one end of the movable rod 9. The output end of the gas cylinder 12 is movably connected with the fixed column 8. The movable rod 9 is provided with a positioning groove 14. The other end of the fixed column 8 is connected with a positioning strip 15 which is slidably connected with the positioning groove 14. The positioning strip 15 is in L shape.

[0022] The damaged brush 1 is lighter in weight and the bristles thereon are shorter, so that the gravity value detected by the gravity sensor 11 is reduced. The gravity sensor 11 sends a signal to the controller 10. The controller 10 controls the gas cylinder 12 to work, so that the output end of the gas cylinder 12 drives the movable rod 9 to move downward, thereby driving the installation plate 2 to descend, and further driving the brush 1 to descend to continue to be used to open the latch of the knitting needle. In the process of moving downward, the positioning strip 15 moves in the positioning groove 14 to guide the movement of the movable rod 9, so that the movable rod 9 moves stably without deviation, thereby driving the installation plate 2 to stably descend and driving the brush 1 to stably descend without deviation, so as to avoid affecting the subsequent use effect of the descended brush 1, and finally realizing that the brush 1 is continuously damaged in use, the damaged brush 1 is lighter in weight, and the brush 1 is descended by the adjusting part 300 to continue to be used to open the latch of the knitting needle.

[0023] A limiting ring 16 is connected to the fixed column 8, and a guide rod 17 matched with the limiting ring 16 is connected to the mounting plate 2 and moves in the limiting ring 16.

[0024] During the working driving of the cylinder 12 to move the movable rod 9 downward, the movable rod 9 drives the mounting plate 2 to descend, and the guide rod 17 moves in the limiting ring 16 to facilitate the guide rod 17 to descend with the mounting plate 2, so that the mounting plate 2 keeps stable during the descending process and will not deviate, and further, the brush 1 keeps stable during the descending process and will not deviate, thereby avoiding affecting the subsequent use effect of the brush 1 after descending.

[0025] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any common change and replacement within the technical scheme range of the present application should be included in the protection range of the present application.
