Description

Technical Field

[0001] This utility model relates to the field of glove manufacturing technology, specifically to a glove manufacturing anti-cut layer sewing device. Background Technology

[0002] In utility model patent application CN222809679U, published on April 29, 2025, entitled "A Sewing Machine for Processing Leather Gloves with Anti-Hand-Pressing Function," this utility model discloses a sewing machine for processing leather gloves with an anti-hand-pressing function, relating to the field of sewing machine technology. It includes an adjustment mechanism comprising a worktable with a collection groove extending through one side of the top of the worktable, a knob on one side of the worktable, a lead screw installed in a slot on the worktable, a bearing seat at the end of the lead screw away from the knob, and two moving blocks on the outside of the lead screw, each with a slider on both sides. This utility model uses clockwise rotation of the adjustment mechanism to press down a pressure plate, which can press and fix the leather gloves laid flat on the platform, preventing the operator from holding the gloves and reducing the risk of hand injury from needle pressure. Rotating the knob drives the lead screw to rotate, causing the leather gloves on the platform to move synchronously, thus achieving the purpose of sewing the leather gloves.

[0003] In the production process of cut-resistant gloves, the stitching precision between the cut-resistant layer and the base fabric directly affects the glove's protection level and wearing comfort. Existing stitching devices have the following key problems: First, uneven stress on the fabric during manual feeding easily leads to wrinkles, affecting the smoothness and strength of the stitches; second, the operating platform is mostly a fixed structure, making it impossible to flexibly adjust the processing position according to the glove size, resulting in low changeover efficiency; third, there is a lack of a dedicated glove contour positioning structure, relying on manual fabric alignment, which is prone to displacement of the cut-resistant layer due to operational errors, resulting in substandard local protection performance after stitching.

[0004] While some devices attempt to integrate positioning components, most are fixed templates of a single specification, lacking versatility and difficult to coordinate with punching and sewing processes. Therefore, developing a cut-resistant layer sewing device with an adjustable positioning template that enables multi-process coordination has become a key requirement for improving glove production quality and efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cut-resistant layer sewing device for glove production, in order to solve the problems of low positioning accuracy, poor changeover efficiency, and unstable feeding mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glove production anti-cut layer sewing device, comprising a sewing table, a base mounted on the top of the sewing table, a single-needle sewing machine mounted on the top of the base, a drive mechanism mounted on the bottom of the sewing table, a punching assembly mounted on the top of the base, a limit assembly mounted on the bottom of the sewing table, a housing mounted on the top of the sewing table, and an operating assembly mounted inside the housing.

[0007] Furthermore, the punching assembly includes an adjustable slide rail base, a bracket, a drive robotic arm, and a punch. The adjustable slide rail base is mounted on the top of the base, the bracket is slidably mounted on the top of the adjustable slide rail base, the drive robotic arm is mounted on the top of the bracket, and the punch is fixedly connected to the output end of the drive robotic arm.

[0008] Furthermore, the punch is made of cemented carbide and has a rounded transition cutting edge at the bottom. A pressure sensor is installed inside the drive robotic arm and is in contact with the top of the punch. The top of the adjusting slide rail base is provided with scale lines.

[0009] Furthermore, the limiting component includes a mounting frame, a support shaft, a drive cylinder, a connecting shaft, and a fabric-pressing limiting fork. The mounting frame is installed at the bottom of the sewing table, the support shaft is installed on the inner wall of the mounting frame, the drive cylinder is installed on the inner side of the support shaft, the output end of the drive cylinder is fixedly connected to the fabric-pressing limiting fork, and the connecting shaft is installed at the front end of the mounting frame.

[0010] Furthermore, the support shaft and the connecting shaft are parallel to each other, and the mounting bracket is connected to the pressure cloth limiting fork through the connecting shaft.

[0011] Furthermore, a silicone pressure block is installed at the top of the fabric pressing and limiting fork, and the bottom of the silicone pressure block is provided with a diamond-shaped anti-slip pattern, and the fabric pressing and limiting fork is located at the edge of the sewing table.

[0012] Furthermore, the operating component includes a transverse lead screw slide rail, a longitudinal lead screw slide rail, a sliding platform, a slot, a connecting rod, and a glove sewing template. The top of the sewing table is fixedly connected to the transverse lead screw slide rail, the top of the transverse lead screw slide rail is mounted with the longitudinal lead screw slide rail, the top of the longitudinal lead screw slide rail is slidably mounted with the sliding platform, a slot is mounted on one side of the sliding platform, a connecting rod is engaged inside the slot, and one end of the connecting rod is fixedly connected to the glove sewing template.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cut-resistant layer sewing device for glove production is reasonable and has the following advantages: (1) The utility uses a silicone pressure block at the top of the pressure fork to provide constant pressure through a driving cylinder. Its bottom anti-slip texture forms multiple points of contact with the fabric surface, increasing the friction coefficient and effectively constraining the displacement of the fabric edge. The limiting component can be used to adopt a non-overlapping sewing method, such as stacking anti-cut and non-anti-cut fabric pieces in parallel. By adjusting the ratio of their feeding speeds, uniform sewing is ensured, avoiding wrinkles or looseness. Then, the combined pieces are placed parallel and symmetrically inside the glove sewing template and fed horizontally at the same speed for sewing, forming a flat combined seam and avoiding high bulging of the seam. The device uses a controller to link and match the conveying speed of the sliding platform with the sewing speed of the single needle sewing machine in real time, avoiding fabric pulling or accumulation caused by asynchronous speeds. This dual guarantee mechanism greatly reduces the problem of fabric wrinkles caused by hand shaking and uneven force when feeding manually. According to actual testing, the flatness error of the sewing stitches is reduced from traditional manual feeding, the flatness is improved, and the aesthetics and firmness of the stitches are significantly enhanced. (2) The glove sewing template adopts a high-precision contour design with a 1:1 ratio to the finished glove contour. The tolerance of the template edge contour is controlled within a reasonable range. The template is also segmented with arc transitions according to the curvature characteristics of different parts of the glove, such as the fingertips, finger seams, and palms, to perfectly fit the three-dimensional structure of the cut-resistant glove. The template surface is also provided with guide grooves that are consistent with the stitch path. After the cut-resistant layer and the base fabric are superimposed, they can be directly embedded into the guide grooves to achieve pre-positioning. The magnetic positioning pins at the four corners of the template are used to fix the material and effectively prevent slippage during the bonding process. On this basis, the horizontal and vertical ball screw slides are precisely controlled by the controller through pulse signals. This dual positioning mechanism of "mechanical contour positioning + precise screw drive" transforms the sewing offset from manual positioning to mechanical positioning, ensuring that the cut-resistant layer can accurately cover all key protective parts of the glove and that the protective performance is evenly distributed. This avoids the problem of reduced cut resistance due to local offset. The glove sewing template is connected to the slot of the sliding platform through the connecting rod. When changing templates of different specifications, there is no need to disassemble other parts. Attached Figure Description

The top of the adjustable slide rail base 501 is provided with scale lines.

[0019] The above structure enables precise control of the punching position and pressure.

[0020] Furthermore, the limiting component 6 includes a mounting frame 601, a support shaft 602, a drive cylinder 603, a connecting shaft 604, and a fabric-pressing limiting fork 605. The mounting frame 601 is installed at the bottom of the sewing table 1. The support shaft 602 is installed on the inner wall of the mounting frame 601. The drive cylinder 603 is installed on the inner side of the support shaft 602. The output end of the drive cylinder 603 is fixedly connected to the fabric-pressing limiting fork 605. The connecting shaft 604 is installed at the front end of the mounting frame 601. The support shaft 602 and the connecting shaft 604 are parallel to each other.

[0021] The above structure features a diamond-shaped anti-slip pattern on the bottom of the silicone pressure block, and the fabric pressing and limiting fork position 605 is located at the edge of the sewing table, ensuring the stability of the fabric during the conveying process.

[0022] Furthermore, the operating component 8 includes a transverse lead screw slide rail 801, a longitudinal lead screw slide rail 802, a sliding platform 803, a slot 804, a connecting rod 805, and a glove sewing template 806. The transverse lead screw slide rail 801 is fixedly connected to the top of the sewing table 1. The longitudinal lead screw slide rail 802 is installed on the top of the transverse lead screw slide rail 801.

The connecting rod 805 is engaged with the inside of the slot 804. One end of the connecting rod 805 is fixedly connected to the glove sewing template 806.

[0023] The above structure achieves multi-directional adjustment of the template through a lead screw and slide rail drive, adapting to the processing of gloves of different specifications.

[0024] Working principle: In use, the operator first lays the glove base fabric and the cut-resistant layer flat on the working surface of the sewing table 1. The sewing speed, stitch length, and punching pressure are set through the external control cabinet. The device is started, and the drive cylinder 603 pushes the fabric pressure limit fork 605 upward, and the silicone pressure block presses the fabric tightly and fixes it. According to the punching requirements, the sliding bracket 502 is moved to the corresponding scale position of the adjusting slide rail base 501, and the locking bolt is tightened. The drive robotic arm 503 drives the punch 504 downward to punch the material. The pressure sensor monitors the pressure in real time. If it exceeds 60N, the drive robotic arm 503 stops. After punching is completed, the servo motor 401 starts, and drives the single-needle sewing machine 3 to work through the gear and transmission belt 404. At the same time, the fabric pressure limit fork 605 moves synchronously with the fabric conveyor to ensure the stability of the fabric during the sewing process. After the sewing is completed, the servo motor 401 stops, the drive cylinder 603 resets, and the processed glove semi-finished product is taken out.

[0025] Secondly, according to the size of the gloves to be produced, the glove sewing template 806 of the corresponding specification is engaged and fixed with the slot 804 of the sliding platform 803 through the connecting rod 805; the starting device controls the transverse lead screw slide rail 801 and the longitudinal lead screw slide rail 802 to drive the sliding platform 803 to move, so that the glove sewing template 806 is aligned with the bottom of the punching assembly 5.

[0026] Finally, the operator overlaps the cut-resistant layer with the glove base fabric and attaches it to the surface of the glove sewing template 806, initially fixing it through the positioning holes on the template; the drive cylinder 603 pushes the fabric pressure limiting fork 605 upward, and the silicone pressure block presses the edge of the fabric tightly; the drive robotic arm 503 drives the punch 504 downward to complete the punching at the preset position, and the pressure sensor monitors the pressure in real time. If the pressure exceeds the set value, the machine will stop immediately for protection; after the punching is completed, the transverse lead screw slide rail 801 and the longitudinal lead screw slide rail 802 drive the sliding platform 803 to move, sending the template and fabric to the bottom of the single-needle sewing machine 3, and simultaneously starting the drive mechanism 4 to drive the sewing machine to work and complete the sewing process; after the sewing is completed, the sliding platform 803 resets, the fabric pressure limiting fork 605 descends, the processed glove semi-finished product is taken out, and the next cycle begins.
