Description

Technical Field

[0001] This utility model relates to the field of roller machine technology, and in particular to a presser foot adjustment structure for a computer roller machine. Background Technology

[0002] The presser foot is one of the components on a roller sewing machine. In order to cooperate with the sewing work of the roller sewing machine, the height of the presser foot needs to be adjusted through a lifting mechanism.

[0003] According to prior art, a double-needle computerized roller presser with a presser foot adjustment structure is disclosed (publication number: CN215163598U), which includes a mounting ring and an adjustment mechanism, and a presser foot body is provided below the mounting ring;

[0004] The adjustment mechanism includes a graduated slide rod, the outer wall of which is fixedly connected to the inner wall of the mounting ring. A movable sleeve is slidably fitted onto the outer wall of the graduated slide rod. A rotating groove is provided at the bottom of the movable sleeve. A through hole is provided at the top of the inner wall of the rotating groove. A rotating rod is rotatably connected to the inner cavity of the through hole. A threaded rod is fixedly connected to the top of the rotating rod. A threaded hole is provided at the bottom of the graduated slide rod. The outer wall of the threaded rod is threadedly connected to the inner cavity of the threaded hole. A pusher is fixedly connected to the bottom end of the rotating rod.

[0005] Existing technology proposes to adjust the position of the pressure foot by moving the sleeve through a screw. However, the screw itself does not have a self-locking feature. The mechanical vibration generated during the operation of the roller machine can easily cause the screw to rotate, which in turn causes the position of the pressure foot to drift and affects the stability of the pressure foot position. Therefore, the existing method of adjusting the sleeve has room for optimization.

[0006] Therefore, we propose a presser foot adjustment structure for a computerized roller press. Utility Model Content

[0007] The present invention mainly solves the technical problem of easy displacement of the sleeve position mentioned above, and provides a presser foot adjustment structure for a computer roller press.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a pressure foot adjustment structure for a computerized roller press, comprising:

[0009] The outer casing has a screw inside, which is slidably connected to the screw. The upper end of the screw is fixedly mounted with a mounting base, and the outer casing is rotatably connected with an adjusting nut, which is threadedly connected to the screw.

[0010] A stop structure is provided at the upper end of the adjusting nut to restrict the rotation of the adjusting nut. The stop structure includes a limiting ring, an anti-slip block, and stop ribs. Several stop ribs are fixedly installed at the upper end of the adjusting nut. Several slots adapted to the stop ribs are opened at the bottom of the limiting ring. The stop ribs can be inserted into the slots. The anti-slip block is fixedly connected to the limiting ring, and the limiting ring is slidably connected to the screw through the anti-slip block.

[0011] In a preferred embodiment of this utility model, the circumferential surface of the screw is provided with threads, the end of the screw is provided with a limiting groove along its radial direction, and the inner wall of the outer sleeve is provided with a protrusion, which is in clearance fit with the limiting groove and slidably connected.

[0012] In a preferred embodiment of this utility model, the adjusting nut is rotatably mounted on the upper end of the outer sleeve, and the inner circumferential surface of the adjusting nut is provided with a threaded groove adapted to the screw rod, and the inner wall of the adjusting nut is threadedly connected to the screw rod.

[0013] In a preferred embodiment of this utility model, the limiting ring forms an annular plate, the anti-detachment block is integrally formed with the limiting ring, the anti-detachment block is slidably connected with the outer sleeve, the diameter of the limiting ring is smaller than the diameter of the adjusting nut, and the limiting ring is located above the adjusting nut.

[0014] In a preferred embodiment of this utility model, the stop rib is integrally formed with the adjusting nut, the stop rib is a prism, and several identical stop ribs are distributed in a ring array on the top surface of the adjusting nut.

[0015] In a preferred embodiment of this utility model, the stop structure further includes a pushing block and a guide groove. The guide groove is formed on the top surface of the adjusting nut. The pushing block is slidably connected to the guide groove. The pushing block can push the limiting ring upward so that the limiting ring separates from the adjusting nut.

[0016] In a preferred embodiment of this utility model, the pushing block is a wedge-shaped block, with the inclined surface of the pushing block facing the circumferential surface of the limiting ring, and an annular groove for the pushing block to enter is provided on the lower end surface of the limiting ring.

[0017] This utility model provides a presser foot adjustment structure for a computerized roller press. It has the following beneficial effects:

[0018] 1. This is a presser foot adjustment structure for a computerized roller press. By rotating the adjusting nut, the adjusting nut pulls the outer sleeve to slide radially along the outer sleeve. The protrusion of the outer sleeve slides within a limiting groove to ensure stable movement of the outer sleeve. Considering that the roller press will vibrate during operation, which can easily cause the adjusting nut to rotate and the outer sleeve to drift, a limiting ring is set. The limiting ring can be made of neodymium iron boron. The limiting ring attracts the metal adjusting nut, and the stop rib is locked into the corresponding slot. The anti-disengagement block is located in the slide groove of the screw, so the limiting ring can only slide radially along the screw and cannot rotate. When the stop rib is engaged with the slot of the limiting ring, the adjusting nut is also locked circumferentially and cannot rotate. This structure not only allows for flexible adjustment of the outer sleeve position but also has excellent stability, preventing the outer sleeve from drifting due to roller press vibration after the position is adjusted.

[0019] 2. This computer roller presser foot adjustment structure, by pinching the circumferential surface of the adjusting nut and pressing the push block with the fingers, allows the push block to slide within the presser. The inclined surface of the push block inserts into the bottom of the limiting ring, and the limiting ring is moved upward by the pressure of the inclined surface of the push block. The anti-detachment block of the limiting ring slides in the limiting groove of the outer sleeve, thereby separating the limiting ring from the adjusting nut. The stop rib disengages from the slot at the bottom of the limiting ring. At this time, the adjusting nut can be freely rotated to adjust the position of the outer sleeve. At the same time, the inclined surface of the push block sliding against the lower end of the limiting ring will not interfere with the rotation of the adjusting nut, which has the characteristics of convenient operation and ensures ease of use.

[0026] A pressure foot adjustment mechanism for a computerized roller press, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The outer sleeve 10 has a screw 11 inside, and the outer sleeve 10 is slidably connected to the screw 11. The upper end of the screw 11 is fixedly installed with a mounting seat. The outer sleeve 10 is rotatably connected with an adjusting nut 12, which is threadedly connected to the screw 11. In this design, the presser foot is fixedly installed on the outer wall of the outer sleeve 10 by bolts, and the mounting seat at the upper end of the outer sleeve 10 is fixed to the roller carriage by bolts.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a stop structure is provided at the upper end of the adjusting nut 12 to restrict its rotation. The stop structure includes a limiting ring 20, an anti-detachment block 21, and stop ribs 22. Several stop ribs 22 are fixedly installed at the upper end of the adjusting nut 12. Several slots for the stop ribs 22 are provided at the bottom of the limiting ring 20, allowing the stop ribs 22 to be inserted into the slots. The anti-detachment block 21 is fixedly connected to the limiting ring 20, and the limiting ring 20 is slidably connected to the screw 11 through the anti-detachment block 21. The circumferential surface of the screw 11 is threaded, and a limit groove is provided at the end of the screw 11 along its radial direction. The inner wall of the outer sleeve 10 is provided with a protrusion, which interacts with the limit groove. The adjusting nut 12 is rotatably mounted on the upper end of the outer sleeve 10. The inner circumferential surface of the adjusting nut 12 is provided with a threaded groove that adapts to the screw 11. The inner wall of the adjusting nut 12 is threadedly connected to the screw 11. The limiting ring 20 forms an annular plate. The anti-detachment block 21 is integrally formed with the limiting ring 20. The anti-detachment block 21 is slidably connected with the outer sleeve 10. The diameter of the limiting ring 20 is smaller than the diameter of the adjusting nut 12. The limiting ring 20 is located above the adjusting nut 12. The stop rib 22 is integrally formed with the adjusting nut 12. The stop rib 22 is a prism. Several identical stop ribs 22 are distributed in a ring array on the top surface of the adjusting nut 12.

[0029] In this design, to flexibly adjust the height of the outer sleeve 10 and thus control the position of the presser foot, the adjusting nut 12 is rotated. The adjusting nut 12 pulls the outer sleeve 10 to slide radially along the outer sleeve 10. The protrusion of the outer sleeve 10 slides within the limiting groove to ensure stable movement of the outer sleeve 10. Considering that the roller carriage will vibrate during operation, which could easily cause the adjusting nut 12 to rotate and cause the position of the outer sleeve 10 to drift, a limiting ring 20 is set. The limiting ring 20 can be made of neodymium iron boron. The limiting ring 20 adsorbs gold... The adjusting nut 12 is made of a metal material, and the stop rib 22 is inserted into the corresponding slot. The anti-disengagement block 21 is located in the slide groove of the screw 11, so the limit ring 20 can only slide radially along the screw 11 and cannot rotate. When the stop rib 22 and the limit ring 20 are engaged in the slot, the adjusting nut 12 is also locked in the circumference and cannot rotate. This not only enables flexible adjustment of the position of the outer sleeve 10, but also has excellent stability and is not easy to drift due to the vibration of the roller after the position of the outer sleeve 10 is adjusted.

[0030] like Figure 4 As shown, the blocking structure also includes a pushing block 23 and a guide groove 24. The top surface of the adjusting nut 12 is provided with a guide groove 24. The pushing block 23 is slidably connected to the guide groove 24. The pushing block 23 can push the limiting ring 20 to move upward so that the limiting ring 20 is separated from the adjusting nut 12. The pushing block 23 is a wedge-shaped block. The inclined surface of the pushing block 23 faces the circumferential surface of the limiting ring 20. The lower end surface of the limiting ring 20 is provided with an annular groove for the pushing block 23 to enter.

[0031] Since the limiting ring 20 and the adjusting nut 12 are fixed by adsorption, when the adjusting nut 12 needs to be rotated to adjust the position of the outer sleeve 10, the limiting ring 20 needs to be manually lifted. The circumferential surface of the adjusting nut 12 is provided with an anti-slip groove. By pinching the circumferential surface of the adjusting nut 12 and pressing the pushing block 23 with your fingers, the pushing block 23 slides inside the pushing block 23. The inclined surface of the pushing block 23 inserts into the bottom of the limiting ring 20. The limiting ring 20 is moved upward by the pressure of the inclined surface of the pushing block 23. The anti-detachment block 21 of the limiting ring 20 slides in the limiting groove of the outer sleeve 10, and then the limiting ring 20 separates from the adjusting nut 12. The stop rib 22 disengages from the slot at the bottom of the limiting ring 20. At this time, the adjusting nut 12 can be rotated freely to adjust the position of the outer sleeve 10. At the same time, the sliding of the inclined surface of the pushing block 23 against the lower end of the limiting ring 20 will not interfere with the rotation of the adjusting nut 12. It has the characteristics of convenient operation and ensures ease of use.

[0032] The working principle of this utility model is as follows: Hold the circumferential surface of the adjusting nut 12 and press the pushing block 23 with your fingers. The pushing block 23 slides within the adjusting nut 12. The inclined surface of the pushing block 23 inserts into the bottom of the limiting ring 20. The limiting ring 20 is pushed upwards by the inclined surface of the pushing block 23. The anti-detachment block 21 of the limiting ring 20 slides within the limiting groove of the outer sleeve 10, thereby separating the limiting ring 20 from the adjusting nut 12. The stop rib 22 disengages from the slot at the bottom of the limiting ring 20. At this point, the adjusting nut 12 can be freely rotated to adjust the position of the outer sleeve 10. 12. The adjusting nut 12 pulls the outer sleeve 10 to slide radially along the outer sleeve 10, thereby adjusting the position of the presser foot. The limiting ring 20 can be made of neodymium iron boron. The limiting ring 20 adsorbs the metal adjusting nut 12, and the stop rib 22 is inserted into the corresponding slot. The anti-disengagement block 21 is located in the slide groove of the screw 11, so the limiting ring 20 can only slide radially along the screw 11 and cannot rotate. When the stop rib 22 is engaged with the slot of the limiting ring 20, the adjusting nut 12 is also locked in the circumferential direction and cannot rotate, thereby achieving circumferential locking and limiting of the adjusting nut 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
