[0001] The utility model belongs to the technical field related to trouser loop machines, in particular to a foot presser device for trouser loop machines. Background Art
[0002] In the clothing industry, there are currently many types of trouser loop machines that can automatically sew trouser loops. Therefore, in order to enable the trouser loop machine to sew the clothes and pants fabric stably, a presser foot device needs to be installed on the trouser loop machine, so that the position of the clothes and pants fabric is pressed by the presser foot device, so that the trouser loop machine can sew stably. However, it still has the following disadvantages in actual use:
[0003] When the existing trouser loop machine presser foot device is used, the trouser loop machine presser foot device will drag the clothes and pants fabric, so that the trouser loop machine presser foot device can continuously sew different positions of the clothes and pants fabric. However, since the existing device does not have the function of limiting the position of the clothes and pants fabric, the clothes and pants fabric is prone to deviation when moving, which will cause the trouser loop machine to sew the wrong position;
[0004] When using the presser foot device of the trouser loop machine, since the device itself does not have the function of auxiliary sliding, when the clothes and pants fabrics are simply pressed by the presser foot device, the clothes and pants fabrics cannot be quickly pulled out at the position of the lower surface of the device. Utility Model Content
[0005] The utility model aims to provide a trouser loop machine presser foot device, which can move the limit strip by rotating the progressive screw rod inside the progressive screw hole, so that the clothes and pants fabric can move along the side of the limit strip and the auxiliary roller is assembled with the presser foot plate, so that the lower surface of the auxiliary roller is flush with the lower surface of the presser foot plate, thereby solving the problem that the clothes and pants fabric is not capable of limiting the position and is prone to deviation when moving, and the problem that the clothes and pants fabric is not capable of assisting sliding.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses a presser foot device for a trouser loop machine, comprising a presser foot plate, a limit strip is arranged at the front position of the presser foot plate, a rotating plate is arranged at the front side of the limit strip, a middle character block is fixed at the rear side of the rotating plate, a progressive screw is fixed at the rear side of the middle character block, a progressive screw hole is penetrated and opened at the position of the progressive screw at the front side of the presser foot plate, the progressive screw spirally passes through the inner position of the progressive screw hole, an auxiliary roller is arranged at the right position of the presser foot plate, a mounting ring is fixed at the position of the right side of the presser foot plate just above the auxiliary roller, and a spring connected with the lower surface of the mounting ring is fixed to the upper surface of the auxiliary roller.
[0008] Furthermore, a center-character hole is formed through the side wall of the limiting strip, and the center-character block is rotatably engaged in the inner position of the center-character hole.
[0009] Furthermore, a movable hole is formed through the front side of the pressure foot plate located on the left side of the progressive screw hole, and a movable rod passing through the inner position of the movable hole is fixed to the rear side of the limiting strip.
[0010] Furthermore, a positioning rod passing through the inner position of the spring is fixed on the upper surface of the auxiliary roller, and the upper end of the positioning rod is located at the inner position of the mounting ring.
[0011] Furthermore, a baffle is provided at the upper end of the positioning rod and is located at the upper surface of the mounting ring.
[0012] Furthermore, a locking screw hole is formed on the upper end surface of the positioning rod, and a locking screw which is spirally disposed inside the locking screw hole is fixed on the lower surface of the baffle.
[0013] The utility model has the following beneficial effects:
[0014] When the utility model is in use, the rotating plate is rotated, thereby the rotating plate drives the middle character block to rotate inside the middle character hole, and thereby drives the progressive screw to move inside the progressive screw hole, and then the rotating plate drives the limiting strip to move away through the middle character block, so that the limiting strip is located at the side edge position of the clothing fabric to be sewn relative to the side of the presser foot plate. Therefore, after the clothing fabric to be sewn is moved, the clothing fabric to be sewn can be slid along the position of the limiting strip, so that the clothing fabric to be sewn can be accurately sewn and the sewing position misalignment is avoided.
[0015] When the utility model is in use, when the auxiliary roller is at different height positions, the auxiliary roller will move upward, and will drive the positioning rod to move upward inside the mounting ring, and will squeeze the spring, thereby allowing the auxiliary roller to be reset at will, and when the clothes and pants fabric to be sewn is moved, the auxiliary roller rotates and rolls, so that the clothes and pants fabric to be sewn can be dragged and slid, which can facilitate the movement of the clothes and pants fabric to be sewn.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0024] See also Figure 1-4 As shown, the utility model is a trouser loop machine presser device, comprising a presser plate 1, a limit strip 2 is arranged at the front position of the presser plate 1, a rotating plate 4 is arranged at the front side of the limit strip 2, a middle character block 401 is fixed to the rear side of the rotating plate 4, a progressive screw 402 is fixed to the rear side of the middle character block 401, a progressive screw hole 102 is penetrated and opened at the position of the progressive screw 402 on the front side of the presser plate 1, and the progressive screw 402 is spirally located in the internal position of the progressive screw hole 102. Therefore, when the staff does not rotate the progressive screw 402, the progressive screw 402 will be limited in the internal position of the progressive screw hole 102, so that the limit strip 2 is positioned, thereby avoiding the position of the limit strip 2. Random deviation occurs, the progressive screw 402 spirally passes through the internal position of the progressive screw hole 102, an auxiliary roller 3 is arranged on the right side of the presser foot 1, and a mounting ring 103 is fixed to the right side surface of the presser foot 1 just above the auxiliary roller 3, and a spring 302 connected to the lower surface of the mounting ring 103 is fixed to the upper surface of the auxiliary roller 3. Since the spring 302 is located between the mounting ring 103 and the auxiliary roller 3, the auxiliary roller 3 will move upward when the auxiliary roller 3 is at different height positions, and will drive the positioning rod 301 to move upward inside the mounting ring 103, squeezing the spring 302, thereby allowing the auxiliary roller 3 to be reset at will.
[0025] Among them Figure 2 , 3 As shown, a center hole 202 is penetrated on the side wall of the limit strip 2, and a center block 401 is rotatably engaged in the internal position of the center hole 202. A movable hole 101 is penetrated on the front side of the presser foot 1 on the left side of the progressive screw hole 102, and a movable rod 201 passing through the internal position of the movable hole 101 is fixed on the rear side of the limit strip 2. When the limit strip 2 is controlled to move away from or close to the presser foot 1, the limit strip 2 will drive the movable rod 201 to slide inside the movable hole 101, thereby ensuring that the limit strip 2 will not rotate when moving.
[0026] Among them Figure 1 , 2 As shown in Figure 4, a positioning rod 301 passing through the inner position of the spring 302 is fixed on the upper surface of the auxiliary roller 3, and the upper end of the positioning rod 301 is located in the inner position of the mounting ring 103, and a baffle 304 is provided on the upper end of the positioning rod 301 and is located on the upper surface of the mounting ring 103. A locking screw hole 303 is opened on the upper end surface of the positioning rod 301, and a locking screw 305 spirally located in the locking screw hole 303 is fixed on the lower surface of the baffle 304. When the auxiliary roller 3 needs to be disassembled, it is only necessary to rotate the baffle 304 so that the baffle 304 drives the locking screw 305 to be screwed out of the locking screw hole 303, so that the locking screw 305 can be removed. The tightening screw 305 is no longer installed inside the mounting ring 103, and the locking screw 305 can be taken out from the mounting ring 103, so that the auxiliary roller 3 can be disassembled. At the same time, when installing the auxiliary roller 3, the positioning rod 301 can be inserted into the mounting ring 103, and the locking screw 305 can be aligned with the position of the locking screw hole 303 and screwed in, so that the baffle 304 can be installed on the positioning rod 301, and the baffle 304 can be supported by the mounting ring 103, so that the baffle 304 drags the auxiliary roller 3, and the lower surface of the auxiliary roller 3 is flush with the lower surface of the presser foot 1.
[0027] A specific application of this embodiment is: through the setting and use of the above-mentioned structure, when the presser foot 1 is used to press the trouser loop, the rotating plate 4 is rotated, thereby the rotating plate 4 drives the middle character block 401 to rotate inside the middle character hole 202, and thereby drives the progressive screw 402 to move inside the progressive screw hole 102, and then the rotating plate 4 will drive the limiting strip 2 to move away through the middle character block 401, so that the limiting strip 2 is located at the side of the clothes and pants fabric to be sewn relative to the side of the presser foot 1. Therefore, after the clothes and pants fabric to be sewn is moved, the clothes and pants fabric to be sewn can be slid along the position of the limiting strip 2, so that the clothes and pants fabric to be sewn can be accurately sewn and the sewing position misalignment can be avoided. At the same time, since the auxiliary roller 3 is located on the left side of the presser foot 1, after the presser foot 1 presses the clothes and pants fabric to be sewn, when the clothes and pants fabric to be sewn is moved, the auxiliary roller 3 rotates and rolls, so that the clothes and pants fabric to be sewn can be dragged and slid.
[0028] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
