Description

Technical Field

[0001] The utility model relates to the technical field of yarn pressing rods, in particular to a trolley yarn pressing rod adjusting device. Background Art

[0002] Yarn pressing rods are primarily used in textile machinery, particularly on knitting equipment such as automatic circular knitting machines, to guide, position, and press the yarn. They ensure stable yarn tension during the knitting process, preventing long floating yarns from flying out of the yarn feeder, thus ensuring fabric quality and production efficiency.

[0003] Different yarn specifications have different requirements for the height of the yarn pressing rod. By adjusting the height of the yarn pressing rod, the yarn can be properly pressed during the unwinding process, thereby avoiding problems such as yarn twisting and loosening. Currently, traditional yarn pressing rods on the market often use a screw to adjust their height. Over long-term use, due to wear and looseness, the screw's stability will decrease, affecting the fixing effect of the yarn pressing rod after the height adjustment is completed, making it inconvenient for users. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a trolley yarn pressing rod adjusting device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6 A trolley yarn pressure rod adjustment device includes a connecting seat 1 and a yarn pressure rod body 2. The connecting seat 1 is fixedly provided with multiple side fixing seats 11 and a middle fixing seat 12. The yarn pressure rod body 2 is provided with two parallel rods, and the top of the yarn pressure rod body 2 is adapted to be fixedly provided with side vertical rods 21 and a middle vertical rod 22 corresponding to the side fixing seats 11 and the middle fixing seat 12. Adjustment seats 3 are fixedly provided on both sides of the top of the middle fixing seat 12. Limiting members 31 are movably provided on the adjustment seats 3, and multiple limiting grooves 221 are adapted to be opened on both sides of the middle vertical rod 22 corresponding to the limiting members 31.

[0022] Among them, two side fixing seats 11 are fixedly provided on each side of the connecting seat 1, and a middle fixing seat 12 is fixedly provided between the two side fixing seats 11, and the yarn pressing rod body 2 on each side is located below the corresponding side fixing seat 11 and the middle fixing seat 12.

[0023] The side uprights 21 all pass through the side fixing seats 11, the center uprights 22 all pass through the center fixing seats 12, and anti-dropping parts are fixedly provided on the tops of the side uprights 21. The anti-dropping parts prevent the side uprights 21 from falling off from the side fixing seats 11.

[0024] The adjustment base 3 has an inwardly defined cavity on the side facing the neutral rod 22, and a movable stopper 31 is disposed within each cavity. Multiple springs 32 are attached to the side of the stopper 31 facing away from the neutral rod 22, with the other ends of the springs 32 connected to the inner wall of the cavity. The springs 32 push the stopper 31 toward the neutral rod 22, thereby pushing the stopper 31 into the stop slot 221.

[0025] A connecting rod 33 is fixedly and vertically provided on one side of the spring 32 on the limiting member 31 , and the other end of the connecting rod 33 extends out from the adjustment seat 3 and is fixedly connected to a magnetic plate 34 .

[0026] The top of each magnetic plate 34 is fixed with a pull plate 35, and both sides of the top of the middle fixing seat 12 are fixed with magnetic blocks 4 that match the magnetic plate 34. The magnetic plates 34 and the magnetic blocks 4 are adapted to attract each other, so that the pulled-out limiter 31 can be prevented from being pushed out again by the elastic force of the spring 32.

[0027] In this embodiment, when the user needs to adjust the height of the yarn pressing rod body 2, he only needs to pull the magnetic plates 34 on both sides outward, so that the connecting rod 33 on the magnetic plate 34 can drive the limiter 31 to retract into the adjustment seat 3. At this time, the spring 32 is compressed, and the pulled-out magnetic plate 34 is attracted by the magnetic block 4 and cannot be reset.

[0028] The user only needs to pull the magnetic plates 34 on both sides outward to contact the clamping between the limiting grooves 221 of the limiting members 31 on both sides, thereby controlling the vertical movement of the neutral rod 22 and adjusting the height of the yarn pressing rod body 2.

[0029] Once the user has adjusted the height of the yarn-pressing rod body 2, they simply move the pull plates 35 inward. The magnetic plates 34 are then forced inward by the pull plates 35, overcoming the magnetic attraction of the magnetic block 4 and automatically returning to their original position due to the elastic force of the spring 32. This allows the stopper 31 to return to its original position within the stop slot 221, re-engaging the centering rod 22 and thus re-securing the yarn-pressing rod body 2.

[0030] Furthermore, when the limiting member 31 is not locked in the limiting groove 221 after being reset, the user only needs to control the neutral rod 21 to move slightly vertically. In this way, when the limiting member 31 is aligned with the limiting groove 221, the limiting member 31 can be automatically pushed into the limiting groove 221 by the elastic force of the spring 32, thereby improving the stability of the device.

[0031] In the present invention, by controlling the limiting members 31 on both sides to be clamped in different limiting grooves 221, the yarn pressing rod body 2 can be adjusted and fixed at different heights, thereby realizing the adjustment of the height of the yarn pressing rod body 2. After the adjustment is completed, the fixing method of the limiting members 31 and the limiting grooves 221 is relatively stable, the yarn pressing rod body 2 is not easy to loosen, and is convenient for users to use.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
