Description

Technical Field

[0001] The utility model belongs to the technical field of circular knitting machine needle production, in particular to a circular knitting machine needle tempering pneumatic clamp. Background Art

[0002] Circular knitting needles, as the name suggests, are key components of circular knitting machines used to weave yarns into fabrics. They are inserted into the needle grooves of the circular knitting machine. With the rotation of the drum and the movement of the knitting needles, the yarns are tightly woven together to eventually form various knitted fabrics. During the manufacturing process of circular knitting needles, multiple processes are required, including tempering heat treatment, to ensure that the circular knitting needles reach the required hardness. When tempering the circular knitting needles, in order to avoid deformation of the circular knitting needles, the staff needs to place the circular knitting needles on a fixture. For example, Chinese Patent Publication No. CN218059083U discloses a method that can The self-adjusting gap tempering fixture includes a fixture frame, a fixture body is fixedly installed in the fixture frame, and a fixing component is movably installed above the fixture body. The utility model can automatically adjust the angle according to different product models by using the fixture during the tempering process, thereby avoiding side bending due to front and back thickness errors and reducing labor costs. The knitting needles are placed on the fixture body, and then the knitting needles are firmly fixed by various side plates, baffles, pressure blocks, pressure strips, and pressure irons in the front, back, left and right directions to ensure shaping during the heat treatment process, while avoiding the generation of front and back bending and scars. The quality of the knitting needles after the heat treatment process is better.

[0003] However, there are some problems with the existing technology: although the clamp can firmly fix the needle and ensure the shaping during the hot working process, in actual use, the staff needs to manually tighten the screws and squeeze the pressure block downward to fix it. This method not only increases the labor intensity of the staff, but also reduces work efficiency. Therefore, we propose a pneumatic clamp for tempering circular knitting machine needles.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5As shown, an embodiment of the utility model provides a pneumatic clamp for tempering needles of a circular knitting machine, comprising a base 1, brackets 2 are fixedly installed on both sides of the top of the base 1, a box body 3 is fixedly installed on the bracket 2, a pressure plate 4 is provided on the box body 3, the pressure plate 4 and the box body 3 are connected by a pneumatic mechanism, the pneumatic mechanism comprises a horizontal plate 5, the horizontal plate 5 is fixedly installed on the top of the pressure plate 4, both ends of the horizontal plate 5 are movably sleeved with vertical rods 6, the bottom end of the vertical rod 6 is fixedly connected to a lifting block 7, a cylinder 8 is fixedly installed on the base 1, the telescopic end of the cylinder 8 is fixedly connected to a push-pull rod 9, and a connecting rod 10 is hinged between the push-pull rod 9 and the lifting block 7.

[0026] After the staff puts the circular knitting needle into the box body 3, by starting the cylinder 8, they can pull the push-pull rod 9 to drive the connecting rod 10 to move, so that the lifting block 7 can drive the vertical rod 6, the horizontal plate 5 and the pressure plate 4 to move downward together.

[0027] Furthermore, a first pressure block 13 is fixedly installed in the middle of the bottom end of the pressure plate 4, and a second pressure block 14 is provided on both sides of the bottom of the pressure plate 4. A slot 15 is provided on the pressure plate 4 above the second pressure block 14, and the second pressure block 14 is connected to the pressure plate 4 through an adjustment component.

[0028] When the pressure plate 4 moves downward, it can drive the first pressure block 13 and the second pressure block 14 to move downward, so that the middle and both ends of the circular machine needle placed inside the box body 3 can be compressed, thereby preventing the middle and both ends of the circular machine needle from bending and deforming during the tempering heat treatment process, thereby improving the production quality of the circular machine needle.

[0029] Furthermore, the adjustment assembly includes a bolt 16, which is movably installed on the top of the pressure plate 4. The bottom end of the bolt 16 passes through the slot 15 and is threadedly sleeved on the second pressure block 14. The second pressure block 14 is movably connected to the pressure plate 4, and the top of the bolt 16 is fixedly connected with a rotary handle 17.

[0030] By loosening the bolt 16 by turning it, the staff can move the second pressure block 14 to adjust the position of the second pressure block 14. After adjustment, the second pressure block 14 can be fixed by tightening the bolt 16. Due to the change in the position of the second pressure block 14, the distance between the two second pressure blocks 14 can be increased or decreased, so that circular machine needles of different lengths can be tightened, thereby improving applicability.

[0031] Furthermore, a round block 11 is fixedly installed on the top of the vertical rod 6, and a spring 12 located between the horizontal plate 5 and the round block 11 is movably sleeved on the outer surface of the vertical rod 6. The two ends of the spring 12 are respectively fixedly connected to the surface of the horizontal plate 5 and the round block 11.

[0032] The spring 12 has good elasticity. When the vertical rod 6 moves downward to drive the first pressure block 13 and the second pressure block 14 to press on the circular knitting needle, the spring 12 can play a buffering role to prevent the first pressure block 13 and the second pressure block 14 from exerting excessive pressure on the circular knitting needle, causing damage and deformation of the circular knitting needle.

[0033] Furthermore, blocks 18 are fixedly mounted on the bottom of the inner wall of the box body 3 , and the blocks 18 are evenly distributed on the inner wall of the box body 3 .

[0034] Through the design of block 18, the staff can place a large number of circular machine needles in the space between the blocks 18, so that the directions of the two ends of a large number of circular machine needles can be basically consistent, avoiding the situation where the circular machine needles are not arranged horizontally or vertically inside the box body 3, which is more conducive to the subsequent first pressing block 13 and the second pressing block 14 to press the circular machine needles in batches.

[0035] Furthermore, movable plates 19 are movably mounted on both ends of the inner wall of the box body 3 , and the movable plates 19 are connected to the box body 3 via a driving mechanism. A through hole 20 is opened on the right side of the box body 3 .

[0036] Furthermore, the driving mechanism includes a bidirectional screw rod 21, which is rotatably connected to the box body 3. Both sides of the outer surface of the bidirectional screw rod 21 are threadedly sleeved with connecting blocks 22, and the other end of the connecting block 22 passes through the through hole 20 and is connected to the movable plate 19.

[0037] By rotating the bidirectional screw 21, the two connecting blocks 22 can drive the two movable plates 19 to move toward or away from each other. When the two movable plates 19 move toward each other, the two ends of a large number of circular knitting needles placed inside the box body 3 can be aligned, so that the second pressing block 14 can simultaneously press the two ends of the circular knitting needles.

[0038] Furthermore, the handle 17 is provided in a sheet shape, and the surface of the handle 17 is provided with anti-slip grooves.

[0039] Since the rotating handle 17 is in a sheet shape and has anti-skid patterns on its surface, it is convenient for a worker to rotate the bolt 16 through the rotating handle 17 , making it convenient for the worker to use.

[0040] When in use, the staff first puts a large number of circular machine needles into the box body 3, so that the two ends of the circular machine needles face the two movable plates 19 respectively and are distributed in the interval between the blocks 18, and then the bidirectional screw rod 21 can be rotated, so that the two connecting blocks 22 can drive the two movable plates 19 to move toward each other, and the two ends of the large number of circular machine needles placed in the box body 3 can be aligned. Then the staff can adjust the position of the second pressing block 14 according to the length of the circular machine needles. When moving the second pressing block 14, the staff can loosen the bolt 16 by turning the handle 17, and then move the two second pressing blocks 14 to increase or decrease the distance between the two second pressing blocks 14, so that it can be moved. The second pressure block 14 is moved to the top of the end of the circular machine needle. After adjustment, the bolt 16 is tightened to fix the second pressure block 14, so that the second pressure block 14 can compress circular machine needles of different lengths, thereby improving applicability. The staff can then start the cylinder 8. Due to the operation of the cylinder 8, the push-pull rod 9 can be pulled to drive the connecting rod 10 to move, so that the lifting block 7 can drive the vertical rod 6, the horizontal plate 5 and the pressure plate 4 to move downward together, and then the first pressure block 13 and the second pressure block 14 can respectively compress and fix the middle and both ends of the circular machine needle, without the need for the staff to manually tighten the screws to fix it, thereby reducing the labor intensity of the staff.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
