[0002] In the hat production process, the sewing of the brim is an important step. The fixtures used in traditional hat single-needle sewing automation equipment usually use a three-point clamping method to fix the brim for subsequent sewing operations. Although this three-point clamping method can fix the brim to a certain extent, there are some problems in the actual processing process.

[0003] Specifically, since the brim of a hat usually has an arc-shaped structure, the three-point clamping method is difficult to fully adapt to its shape, resulting in wrinkles on the outside of the brim during the sewing process. Such wrinkles not only affect the appearance quality of the hat, but may also reduce its service life and comfort. In addition, the existing clamps lack the force to pull outward when clamping the brim of the hat, and cannot effectively prevent wrinkles from occurring during the sewing process.

DETAILED DESCRIPTION

[0035] 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.

[0037] Reference Figure 1-Figure 13The present invention discloses a tool fixture for a single-needle sewing automation device for hats, comprising a base 100, the base 100 is provided with an arc-shaped needle and thread groove 103, the base 100 is provided with a mounting seat 101, the base 100 is provided with a first pin seat 201, the first pin seat 201 is rotatably connected with a first flip plate 202, the mounting seat 101 is provided with a first driving component 200 for driving the first flip plate 202 to flip around the first pin seat 201, the first flip plate 202 is provided with a first through slot 203, and a second clamping portion 500 is provided in the first through slot 203; a second pin seat 301 is installed on the base 100, the second pin seat 301 is rotatably connected with a first flip plate 202, There are two flip plates 302, a first support plate 303 is provided on the second flip plate 302, a support frame 305 is connected between the first support plate 303 and the second flip plate 302, a second driving assembly 300 for driving the second flip plate 302 to flip around the second pin seat 301 is installed on the base 100, the second flip plate 302 is semi-annular, and the semi-annular second flip plate 302 is provided with second through grooves 304 distributed in a circumference, and each second through groove 304 is provided with a first clamping part 400. After the object to be processed is put into the workstation and the second clamping part 500 contacts the object to be processed, the second flip plate 302 flips and drives the first clamping part 400 to contact the object to be processed.

[0038] According to the solution of the present invention, the brim to be processed is first placed at an appropriate position of the base 100 to ensure that the brim matches the arc-shaped needle and thread groove 103. The second clamping portion 500 first contacts a specific part of the brim to prepare for subsequent fixation. The first driving component 200 is started to drive the first flip plate 202 to flip around the first pin seat 201. Since the first flip plate 202 is provided with a first through groove 203 and the first through groove 203 is provided with a second clamping portion 500, as the first flip plate 202 flips, the second clamping portion 500 will perform a preliminary clamping of the brim to be processed. The second driving assembly 300 is then started to drive the second flip plate 302 to flip around the second pin seat 301. Since the second flip plate 302 is semi-annular in design and is provided with second through grooves 304 distributed in a circumference, each second through groove 304 is provided with a first clamping portion 400. Therefore, during the flipping process of the second flip plate 302, the first clamping portion 400 will be pressed along the edge of the brim, thereby achieving multi-point clamping of the brim, ensuring its stability during the sewing process, and effectively preventing wrinkles from occurring during the sewing process.

[0039] In one embodiment, the first clamping portion 400 includes a first clamping base 401 installed in each second through slot 304, a lifting plate 402 is slidably connected to the center of the first clamping base 401, a first roller 403 is provided at the bottom of the lifting plate 402, one end of the first clamping base 401 is connected to an elastic winding assembly 404, and the other end of the first clamping base 401 is rotatably connected to a third roller 417, and a soft cloth 405 is provided at the output end of the elastic winding assembly 404, and the end of the soft cloth 405 away from the elastic winding assembly 404 is sequentially passed through After passing through the first roller 403 and the third roller 417, it is connected to the top of the lifting plate 402. When the lifting plate 402 moves upward, a pulling force is applied to the soft fabric 405, and the soft fabric 405 extends from the elastic winding component 404. When the lifting plate 402 moves downward, the elastic winding component 404 stores the soft fabric 405. A reset component is provided in the first clamping base 401. In a natural state, the reset component is used to drive the lifting plate 402 to move downward. A tensioning component is also provided on the first clamping base 401, and the tensioning component is used to tension the soft fabric 405.

[0040] With such a solution, when the fixture starts working, the lifting plate 402 in each first clamping base 401 is first at the lowest position of its motion range. At this time, the reset component (such as a spring or other elastic element) keeps the lifting plate 402 in a downward motion state, and the soft fabric 405 is in a state of being received by the elastic winding component 404. When the brim to be processed is placed at a predetermined position and the second flip plate 302 starts to flip, so that the first clamping part 400 approaches the brim, the lifting plate 402 starts to move upward. As the lifting plate 402 rises, the lifting plate 402 applies a pulling force to the soft fabric 405, causing the soft fabric 405 to gradually extend out of the elastic winding component 404, and the bottom surface of the soft fabric 405 and the fabric on the surface of the brim form an effect of pulling outward, and the annular design can synchronously pull the soft fabric 405 outward. , thereby avoiding wrinkles. The tensioning component is used to ensure that the soft fabric 405 maintains appropriate tension during the clamping process, which can prevent unstable clamping caused by fabric relaxation, and can also ensure that the clamping force is evenly distributed to avoid unnecessary pressure or deformation on the hat. When the hat is sewn and the tooling fixture releases the hat, the lifting plate 402 moves downward under the action of the reset component, and the soft fabric 405 is re-stored under the drive of the elastic winding component 404, ready for the next clamping operation. The soft fabric 405 is used as the clamping medium, which can better adapt to the shape of the brim of the hat, and can avoid indentations or damages that may be caused by traditional rigid clamps while preventing wrinkles. Through the innovative clamping mechanism of the soft fabric 405, flexible and uniform clamping of the brim of the hat is achieved, thereby improving the sewing quality and production efficiency.

[0041] Optionally, in one embodiment, the reset assembly includes two third baffles 413 installed on the lifting plate 402, a second slide bar 415 is connected between the two third baffles 413, a fourth baffle 414 is installed on the first clamping base 401, the second slide bar 415 is slidably connected to the fourth baffle 414, a second spring 416 is sleeved on the second slide bar 415, and both ends of the second spring 416 are respectively against the third baffle 413 and the fourth baffle 414 at the bottom.

[0042] When the lifting plate 402 is lowered, the second spring 416 is pressed against the lifting plate 402, and the second spring 416 is pressed against the lifting plate 402, and the second spring 416 is pressed against the lifting plate 402, and the second spring 416 is pressed against the lifting plate 402.

[0043] Optionally, in one embodiment, the tensioning assembly includes a support rod 406 installed on both sides of the first clamping base 401, a sliding frame 407 is slidably connected to the inner side of the support rod 406, a second roller 412 is rotatably arranged on the inner side of the sliding frame 407, a first baffle 408 is connected to the inner side of the support rod 406, a first slide bar 409 is fixedly connected to the first baffle 408, the sliding frame 407 is slidably connected to the first slide bar 409, the end of the first slide bar 409 away from the first baffle 408 is connected to the second baffle 410, the first slide bar 409 is sleeved with a first spring 411, and the two ends of the first spring 411 are respectively against the sliding frame 407 and the second baffle 410.

[0044] With such a scheme, the tensioning assembly is designed to ensure that the soft fabric 405 can maintain an appropriate tension during the clamping process, thereby ensuring the stability and effectiveness of the clamping. When the lifting plate 402 moves upward, the soft fabric 405 is subjected to tension and extends out of the elastic winding assembly 404. Under the tension of the soft fabric 405, the sliding frame 407 slides along the sliding direction of the first sliding rod 409 toward the first baffle 408. Since the first spring 411 is sleeved on the first sliding rod 409, and its two ends are respectively against the sliding frame 407 and the second baffle 410, the first spring 411 will be compressed and store elastic potential energy. As the sliding frame 407 slides, the position of the second roller 412 also changes accordingly. The shaft 412 applies a reverse tension to the soft fabric 405 through the elasticity of the first spring 411, thereby ensuring that the soft fabric 405 maintains an appropriate tension during the clamping process. The magnitude of the tension can be adjusted by adjusting the initial compression of the first spring 411 or selecting springs with different stiffness. When the lifting plate 402 moves downward, the soft fabric 405 is retracted under the action of the elastic winding assembly 404, and the first spring 411 releases the stored elastic potential energy, pushing the sliding frame 407 to slide along the first sliding rod 409 in a direction away from the first baffle 408, thereby returning to the initial position. The tensioning assembly can dynamically adjust the tension of the soft fabric 405 through the interaction between the sliding frame 407 and the first spring 411. This dynamic adjustment mechanism ensures that the soft fabric 405 can always fit the shape of the brim during the clamping process, thereby improving the stability and effectiveness of the clamping.

[0045] In one embodiment, the second clamping portion 500 includes a second clamping base 501 slidably connected to the first through slot 203, the second clamping base 501 is rotatably connected to a rotating wheel 505, a pin shaft 504 is connected between the rotating wheel 505 and the second clamping base 501, the bottom of the rotating wheel 505 is connected to a pressure plate 506 through a connecting rod, a buffer portion is provided at the bottom of the pressure plate 506, and an elastic unit is provided in the first through slot 203.

[0046] With such a solution, when the brim needs to be clamped, the second clamping base 501 is connected to the first through slot 203 by sliding, and can reciprocate along the direction of the through slot. The rotating wheel 505 is rotatably connected to the second clamping base 501 through the pin 504, allowing the rotating wheel 505 to rotate within a certain range. When the first flip plate 202 flips and clamps, the buffer part at the bottom of the pressure plate 506 contacts the brim and applies pressure. Due to the possible differences in the shape and material of the brim, the clamping force is unevenly distributed or there is rigid pulling. At this time, the elastic unit plays a role in the first through slot 203. An adjustable movement space can be provided for the second clamping base 501. If the clamping force is too large or the shape of the brim is irregular, the elastic unit will allow the second clamping base 501 to perform a small reciprocating motion in the first through groove 203 to buffer the clamping force and avoid damage to the surface of the brim. The movement is automatically adjusted and can change in real time according to the change of the clamping force, thereby ensuring the stability and safety of the clamping. This embodiment can effectively buffer the rigid pulling of the clamping force on the surface of the brim, avoid damage caused by excessive clamping force or uneven distribution, and protect the integrity and aesthetics of the brim.

[0047] Optionally, in one embodiment, the elastic unit includes two groups of third sliding bars 502 installed in the first through groove 203, each group has two third sliding bars 502 and are arranged in parallel up and down, the second clamping base 501 is slidably connected to the two groups of third sliding bars 502, and two groups of third springs 503 are sleeved on the third sliding bars 502, the two groups of third springs 503 are symmetrically arranged, and the two ends of the third springs 503 are respectively against the second clamping base 501 and the inner wall of the first through groove 203.

[0048] Optionally, in one embodiment, the buffer portion includes a buffer plate 507, which is detachably connected to the bottom of the pressure plate 506, and a fourth slide bar 509 is connected to the buffer plate 507, and the fourth slide bar 509 is slidably connected to the pressure plate 506. A fourth spring 510 is sleeved on the fourth slide bar 509, and two ends of the fourth spring 510 are respectively against the pressure plate 506 and the buffer plate 507.

[0049] The buffer part also includes a protective plate 508, and the fourth sliding rod 509 is divided into multiple groups and fixedly connected to the bottom of the protective plate 508. Each fourth sliding rod 509 is provided with a screw hole. A through hole is provided on the buffer plate 507 at a position corresponding to the fourth sliding rod 509, and a bolt 511 is connected between the buffer plate 507 and the fourth sliding rod 509.

[0050] With such a solution, the buffer plate 507 is detachably connected to the protective plate 508 through the cooperation of the bolt 511, the through hole and the screw hole. This detachable design makes it convenient to replace and repair the buffer plate 507, and improves the maintenance efficiency of the fixture. When the pressing plate 506 moves downward to clamp the brim of the hat, the buffer plate 507 first contacts the brim of the hat. Due to the sliding connection between the fourth slide bar 509 and the pressure plate 506, when the brim surface is irregular or there is a large resistance, the buffer plate 507 can slide on the fourth slide bar 509 and compress the fourth spring 510 at the same time. The function of the fourth spring 510 is to provide a reverse elastic force for the buffer plate 507. This elastic force can help the buffer plate 507 better adapt to the shape of the brim surface and avoid rigid contact and damage. Since the buffer plate 507 and the protective plate 508 are connected by multiple groups of fourth slide bars 509, this multi-point support structure can enhance the stability of the buffer plate 507 and the uniformity of clamping. By setting the buffer part, the damage to the brim surface caused by the clamping force can be effectively buffered, thereby improving the stability of the clamping.

[0051] Optionally, in one embodiment, a mounting hole 102 is provided on the base 100 .

[0052] Optionally, in one embodiment, a stopper 204 is provided on the base 100 and located at the needle and thread groove 103 , and the stopper 204 is used to achieve preliminary positioning of the brim of the hat.

[0053] The present invention solves the problem that wrinkles are easily formed on the outer side of the brim during the single-needle sewing process of the hat in the prior art by improving the design of the tooling fixture. By combining middle clamping with re-clamping of the edge arc, and applying a pulling force to the outside, the brim is firmly fixed and the sewing surface is flat, thereby improving the overall quality of the hat.

[0054] Since the second flip plate 302 is semi-circular in design and is provided with second through grooves 304 distributed in a circumference, and each second through groove 304 is provided with a first clamping portion 400, during the flipping process of the second flip plate 302, the first clamping portion 400 will be pressed along the edge of the brim, thereby achieving multi-point clamping of the brim, ensuring its stability during the sewing process, and effectively preventing wrinkles from occurring during the sewing process.

[0055] Using soft fabric 405 as the clamping medium can better adapt to the shape of the brim, prevent wrinkles and avoid indentations or damage that may be caused by traditional rigid clamps. Through the innovative soft fabric 405 clamping mechanism, flexible and uniform clamping of the hat brim is achieved, improving sewing quality and production efficiency.

[0056] By arranging an elastic unit in the first through slot 203, the second clamping base 501 is allowed to perform a small reciprocating motion in the first through slot 203 to buffer the clamping force and avoid damage to the brim surface.
