Description

Technical Field

[0001] This utility model relates to the field of sewing device technology, and in particular to a sewing device for processing waterproof sportswear. Background Technology

[0002] In the production and processing of sportswear fabrics, it is often necessary to use sewing devices to sew the edges of the fabric. However, ordinary sewing devices do not have the function of smoothing and defining the edges of the fabric. Because the fabric is flexible, wrinkles will appear on the surface of the fabric when the workers place the sportswear to be processed on the workbench. Workers need to spend a lot of time smoothing it out. Moreover, during the sewing process, due to the lack of bottom fixation, the garment is still prone to wrinkling when it moves forward under the action of the sewing machine, thus affecting the quality of the sewing.

[0003] Chinese utility model patent CN214362081U discloses a right-angle binding and sewing device, including a sewing machine, an operating table, a sewing area, and a support rod. The operating table is fixedly mounted on the support rod, the sewing machine is mounted on the operating table, the sewing area is provided on the operating table, and a binding mechanism is provided on the sewing area. The binding mechanism includes a base with a U-shaped cross-section. A sliding groove is provided on the inner wall of the base, and an adjusting baffle is slidably connected to the sliding groove. The adjusting baffle has a U-shaped cross-section and an adjustment part on its upper part. A first limiting baffle and a second limiting baffle are provided at the open end of the base. First through grooves are provided on both the upper and lower surfaces of the base, and second through grooves are provided on both the upper and lower surfaces of the adjusting baffle. This utility model can ensure that the binding and fabric do not wrinkle during the sewing process, effectively ensuring the quality of the sewing.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: While the device reduces the difficulty for workers to edge the fabric by placing the edge binding strip using an edge binding mechanism mounted on the operating table, in actual use, the edge binding mechanism has a limited length to prevent it from interfering with the worker's operation. When the edge binding strip is connected to the edge binding mechanism, part of the mechanism is directly exposed outside the edge binding mechanism. Workers are prone to touching this exposed portion of the edge binding strip during edge binding operations, causing the edge binding strip's position to change and resulting in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a sewing device for processing waterproof sportswear.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sewing device for processing waterproof sportswear, comprising an operating table, a connecting rod connected to the operating table, a roller installed at the bottom of the connecting rod, and a sewing machine installed on the operating table. A first C-shaped plate is installed on the upper surface of the operating table, a fixing plate is fixed on the side wall of the first C-shaped plate, and the fixing plate has a mounting hole for installing the fixing plate. A sliding groove is opened on the upper surface of the first C-shaped plate, and a sliding block is slidably arranged in the sliding groove. A first C-shaped block is slidably arranged on the inner wall of the first C-shaped plate, and the first C-shaped block and the sliding block are fixed to each other. A first L-shaped block is integrally formed on the inner top wall and inner bottom wall of the first C-shaped plate. A limiting component for limiting the end of the binding strip is provided on the operating table.

[0007] By adopting the above technical solution, the production process of sportswear requires the splicing and sewing of multiple fabrics. Before sewing, the edges of the fabrics need to be hemmed. At this time, the worker needs to connect the fixing plate to the operating table, align the mounting holes on the fixing plate with the corresponding fixing holes on the operating table, and connect the fixing bolts through the mounting holes to the operating table. This ensures that the first C-shaped plate and the fixing plate remain stable under the action of the fixing bolts.

[0008] Next, the worker needs to fold the binding strip into a C-shape and place it between the first C-shaped block and the two first L-shaped blocks to initially stabilize one end of the binding strip. Then, the worker needs to hold one end of the binding strip and adjust the other end to connect it with the second C-shaped plate, thus initially stabilizing the binding strip. Next, the worker needs to slide the sliding block to adjust the positions of the first and second C-shaped blocks, allowing the first and second L-shaped blocks to cooperate and limit the binding strip's movement. Finally, the worker needs to rotate the second C-shaped plate to change it from a vertical to a horizontal position. When the second C-shaped plate is stable, the end of the binding strip furthest from the first C-shaped plate moves with it and remains stable, reducing the probability of accidental contact and improving the user experience. Then, the staff only needs to place the fabric to be bound on the presser foot of the sewing machine and turn on the sewing machine to bind the edge of the fabric with the binding strip, thus reducing the difficulty of operation for the staff.

[0009] Furthermore, the limiting component includes a silicone strip fixed at one end to the side wall of the first C-shaped block, a second C-shaped plate connected to the other end of the silicone strip, a second C-shaped block slidably disposed on the inner wall of the second C-shaped plate, two second L-shaped blocks respectively installed on the inner top wall and inner bottom wall of the second C-shaped plate, and a fixing device disposed on the second C-shaped plate for fixing the second C-shaped plate.

[0010] By adopting the above technical solution, when the second C-shaped plate is not subjected to external force, its right side is flush with the right side of the first C-shaped plate under the action of the silicone strip. When the worker needs to perform edge binding, the worker needs to fold the edge binding strip into a C-shape, placing one end of the edge binding strip between the first C-shaped block and the two first L-shaped blocks, and then smoothing the other end of the edge binding strip to move it between the second C-shaped block and the two second L-shaped blocks. Subsequently, the worker needs to adjust the positions of the first C-shaped block and the second C-shaped block in sequence so that the widths of the first C-shaped block, the second C-shaped block, and the edge binding strip are compatible. Further, the worker needs to rotate the second C-shaped plate, which will cause the second C-shaped plate to bend and change from a vertical state to a horizontal state, thereby causing one end of the edge binding strip to move with the second C-shaped plate. Subsequently, the worker needs to activate the fixing device to stabilize the second C-shaped plate, thereby keeping the edge binding strip in an arc state, thus reducing the probability of the worker accidentally touching the edge binding strip in subsequent operations, and thus improving the user experience of the device.

[0011] Furthermore, both the first C-shaped plate and the second C-shaped plate have threaded rods threadedly connected to their upper surfaces.

[0012] By adopting the above technical solution, when the staff adjusts the positions of the first C-shaped block and the second C-shaped block to match the width of the first C-shaped block and the second C-shaped block with the edge banding strip, the staff only needs to rotate the two threaded rods in sequence to make the two threaded rods press against the first C-shaped block and the second C-shaped block in sequence, thereby keeping the first C-shaped block and the second C-shaped block stable and reducing the probability of the positions of the first C-shaped block and the second C-shaped block changing during the edge banding process.

[0013] Furthermore, a stabilizing groove is provided on the side wall of the second C-shaped plate, and a moving groove is provided through the inner bottom wall of the stabilizing groove. The fixing device includes a stabilizing rod slidably disposed in the stabilizing groove and a moving rod slidably disposed in the moving groove. The stabilizing rod and the moving rod are fixed to each other. A moving hole matching the moving rod is provided on the upper surface of the operating table.

[0014] By adopting the above technical solution, when both ends of the binding strip are located within the first C-shaped block and the second C-shaped block respectively, the operator only needs to rotate the second C-shaped plate to make the binding strip rotate with it, thereby bending the end of the binding strip outside the first C-shaped plate. This reduces the probability of the operator accidentally touching the binding strip during subsequent operations. Furthermore, when the moving groove and the moving hole are aligned, the operator only needs to press down on the stabilizing rod to make the moving rod move with the stabilizing rod, thereby connecting the lower end of the moving rod with the moving hole. This allows the moving rod to block the second C-shaped plate, thus stabilizing the second C-shaped plate and the binding strip. Subsequently, the operator only needs to place the fabric to be bound on the presser foot of the sewing machine and start the sewing machine to bind the edge of the fabric with the binding strip, thereby reducing the operator's operational difficulty.

[0015] Furthermore, a first magnetic strip is embedded on the bottom surface of the second C-shaped plate, and a second magnetic strip is embedded on the upper surface of the operating table, with the first and second magnetic strips attracting each other.

[0016] By adopting the above technical solution, when the worker rotates the second C-shaped plate, the edge banding strip rotates along with the second C-shaped plate, eventually aligning the moving groove with the moving hole. At this point, if the worker releases the second C-shaped plate, the second C-shaped plate remains stable because the first and second magnetic strips attract each other, thus reducing the difficulty for the worker to move the moving rod subsequently.

[0017] Furthermore, a support plate is slidably disposed on the side wall of the second C-shaped block near the first C-shaped block, and a receiving groove matching the support plate is formed on the side wall of the first C-shaped block near the second C-shaped block.

[0018] By adopting the above technical solution, when the second C-shaped plate is not subjected to external force, its right side is flush with the right side of the first C-shaped plate under the action of the silicone strip. At this time, the worker needs to move both ends of the binding strip into the first and second C-shaped blocks respectively, and slide the support plate to connect the support plate with the receiving groove, so that the first and second C-shaped blocks can move synchronously. At this time, the worker only needs to slide the sliding block to adjust the position of the first and second C-shaped blocks simultaneously, thereby reducing the difficulty for the worker to match the position of the first and second C-shaped blocks with the width of the binding strip.

[0019] Furthermore, the sidewalls of the support plate are equipped with sliders to reduce the difficulty for workers to move the support plate.

[0020] Furthermore, reinforcing ribs are provided on the side wall of the silicone strip away from the first L-shaped block.

[0021] By adopting the above technical solution, the reinforcing ribs improve the structural strength of the silicone strip, thereby increasing the probability that the silicone strip remains vertical when it is not subjected to external force. This, in turn, increases the probability that the right side of the second C-shaped plate is flush with the right side of the first C-shaped plate when it is not subjected to external force, thus improving the user experience for staff.

[0022] In summary, this utility model has the following beneficial effects: 1. In this application, the production process of sportswear requires the splicing and sewing of multiple fabrics. Before sewing, the workers need to hem the edges of the fabrics. At this time, the workers need to connect the fixing plate to the operating table, aligning the mounting holes on the fixing plate with the corresponding fixing holes on the operating table, and connecting the fixing bolts through the mounting holes to the operating table, thus stabilizing the first C-shaped plate and the fixing plate under the action of the fixing bolts. Subsequently, the workers need to fold the binding strip into a C-shape and place it between the first C-shaped block and the two first L-shaped blocks, thus initially stabilizing one end of the binding strip. Further, the workers need to hold one end of the binding strip and adjust the other end, thus connecting the other end of the binding strip with the second C-shaped plate, thereby initially stabilizing the binding strip. Subsequently, the workers need to slide the sliding block to adjust the position of the first C-shaped block and the second C-shaped block, thereby allowing the first L-shaped block and the second L-shaped block to cooperate and limit the binding strip. Furthermore, the operator needs to rotate the second C-shaped plate to change it from a vertical to a horizontal position. When the second C-shaped plate remains stable, the end of the edge banding strip furthest from the first C-shaped plate moves with the second C-shaped plate and remains stable, thereby reducing the probability of the operator accidentally touching the edge banding strip and improving the user experience of the device. 2. In this application, when the second C-shaped plate is not subjected to external force, its right side is flush with the right side of the first C-shaped plate under the action of the silicone strip. When the worker needs to perform edge binding, the worker needs to fold the edge binding strip into a C-shape, placing one end of the edge binding strip between the first C-shaped block and the two first L-shaped blocks, and then smoothing the other end of the edge binding strip to move it between the second C-shaped block and the two second L-shaped blocks. Subsequently, the worker needs to adjust the positions of the first C-shaped block and the second C-shaped block in sequence to make the widths of the first C-shaped block, the second C-shaped block, and the edge binding strip compatible. Further, the worker needs to rotate the second C-shaped plate, which will cause the second C-shaped plate to bend and change from a vertical state to a horizontal state, thereby causing one end of the edge binding strip to move with the second C-shaped plate. Subsequently, the worker needs to activate the fixing device to keep the second C-shaped plate stable, thereby keeping the edge binding strip in an arc state, thus reducing the probability of the worker accidentally touching the edge binding strip during subsequent operations, and thus improving the user experience of the device. 3. In this application, when the worker adjusts the positions of the first C-shaped block and the second C-shaped block so that the widths of the first C-shaped block, the second C-shaped block and the binding strip are adapted to each other, the worker only needs to rotate the two threaded rods in sequence to make the two threaded rods press against the first C-shaped block and the second C-shaped block in sequence, thereby keeping the first C-shaped block and the second C-shaped block stable, and thus reducing the probability of the positions of the first C-shaped block and the second C-shaped block changing during the binding process.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-6As shown in the embodiment of this application, a sewing device for processing waterproof sportswear is disclosed, including an operating table 1, a connecting rod 11, rollers 2, a sewing machine 21, a first C-shaped plate 3, a fixing plate 32, a sliding block 4, a first C-shaped block 41, a first L-shaped block 42, a limiting component 5, a threaded rod 7, a first magnetic strip 8, a second magnetic strip 81, a support plate 82, a slider 84, and a reinforcing rib 9. The connecting rod 11 is connected to the operating table 1 and is used to support the operating table 1. The rollers 2 are installed at the bottom of the connecting rod 11, and the sewing machine 21 is installed on the operating table 1. The first C-shaped plate 3 is a plate-like structure with a C-shaped cross-section and is installed on the upper surface of the operating table 1. The fixing plate 32 is a plate-like structure and is fixed to the side wall of the first C-shaped plate 3. The fixing plate 32 has mounting holes 33 for mounting the fixing plate 32. The upper surface of the first C-shaped plate 3 has a sliding groove 31. The sliding block 4 is a block structure and is slidably disposed in the sliding groove 31. The first C-shaped block 41 is a block structure with a C-shaped cross-section and is slidably disposed on the inner wall of the first C-shaped plate 3. The first L-shaped block 42 is a block structure with an L-shaped cross-section. Two first L-shaped blocks 42 are provided and are respectively installed on the inner top wall and inner bottom wall of the first C-shaped plate 3.

[0027] A limiting component 5 is mounted on the operating table 1 to limit the end of the binding strip. The limiting component 5 includes a silicone strip 51, a second C-shaped plate 52, a second C-shaped block 53, a second L-shaped block 54, and a fixing device 6. One end of the silicone strip 51 is fixed to the side wall of the first C-shaped block 41. The second C-shaped plate 52 is a plate-like structure with a C-shaped cross-section, and the other end of the second C-shaped plate 52 is connected to the silicone strip 51. The second C-shaped block 53 is a block-like structure with a C-shaped cross-section, and the second C-shaped block 53 is slidably mounted on the inner wall of the second C-shaped plate 52. The second L-shaped block 54 is a block-like structure with an L-shaped cross-section, and two second L-shaped blocks 54 are provided and respectively installed on the inner top wall and inner bottom wall of the second C-shaped plate 52.

[0028] When the second C-shaped plate 52 is not subjected to external force, its right side is flush with the right side of the first C-shaped plate 3 under the action of the silicone strip 51. When the worker needs to perform edge binding, the worker needs to fold the edge binding strip into a C-shape, placing one end of the edge binding strip between the first C-shaped block 41 and the two first L-shaped blocks 42, and then smoothing the other end of the edge binding strip to move it between the second C-shaped block 53 and the two second L-shaped blocks 54. Subsequently, the worker needs to adjust the positions of the first C-shaped block 41 and the second C-shaped block 53 in sequence so that the widths of the first C-shaped block 41, the second C-shaped block 53, and the edge binding strip are compatible. Further, the worker needs to rotate the second C-shaped plate 52, which will cause the second C-shaped plate 52 to bend and change from a vertical state to a horizontal state, thereby causing one end of the edge binding strip to move with the second C-shaped plate 52. Subsequently, the staff needs to activate the fixing device 6 to stabilize the second C-shaped plate 52, thereby keeping the edge banding strip in an arc state. This reduces the probability of the staff accidentally touching the edge banding strip during subsequent operations, thus improving the user experience of the device.

[0029] The bottom surface of the second C-shaped plate 52 has a movable groove 55, and a stabilizing groove 56 is formed through the inner wall of the movable groove 55. A fixing device 6 is installed on the second C-shaped plate 52 to fix the second C-shaped plate 52. The fixing device 6 includes a movable rod 61 and a stabilizing rod 62. The stabilizing rod 62 is a rod-shaped structure and is slidably disposed in the stabilizing groove 56. The movable rod 61 is a rod-shaped structure and is slidably disposed in the movable groove 55. The stabilizing rod 62 and the movable rod 61 are fixed to each other, and the upper surface of the operating table 1 has a movable hole 71 that matches the movable rod 61.

[0030] When both ends of the binding strip are located within the first C-shaped block 41 and the second C-shaped block 53 respectively, the operator only needs to rotate the second C-shaped plate 52 to make the binding strip rotate with it, thus bending the end of the binding strip outside the first C-shaped plate 3, thereby reducing the probability of the operator accidentally touching the binding strip in subsequent operations. Furthermore, when the moving groove 55 is aligned with the moving hole 71, the operator only needs to press down on the stabilizing rod 62 to make the moving rod 61 move with it, thus connecting the lower end of the moving rod 61 with the moving hole 71, thereby blocking the second C-shaped plate 52 and stabilizing the second C-shaped plate 52 and the binding strip. Then, the operator only needs to place the fabric to be bound on the presser foot of the sewing machine 21 and turn on the sewing machine 21 to bind the edge of the fabric with the binding strip, thus reducing the difficulty of operation for the operator.

[0031] Two threaded rods 7 are provided and are sequentially threaded to the upper surfaces of the first C-shaped plate 3 and the second C-shaped plate 52. When the worker adjusts the positions of the first C-shaped block 41 and the second C-shaped block 53 so that the width of the first C-shaped block 41 and the second C-shaped block 53 matches the width of the binding strip, the worker only needs to rotate the two threaded rods 7 in sequence to make the two threaded rods 7 press against the first C-shaped block 41 and the second C-shaped block 53 in sequence, thereby keeping the first C-shaped block 41 and the second C-shaped block 53 stable, and thus reducing the probability of the positions of the first C-shaped block 41 and the second C-shaped block 53 changing during the binding process.

[0032] The first magnet strip 8 has a sheet-like structure and is embedded in the bottom surface of the second C-shaped plate 52. The second magnet strip 81 has a sheet-like structure and is embedded in the upper surface of the operating table 1, and the first magnet strip 8 and the second magnet strip 81 are attracted to each other.

[0033] When the worker rotates the second C-shaped plate 52, the binding strip rotates along with the second C-shaped plate 52, eventually aligning the moving groove 55 with the moving hole 71. At this point, if the worker releases the second C-shaped plate 52, the second C-shaped plate 52 remains stable because the first magnetic strip 8 and the second magnetic strip 81 attract each other, thus reducing the difficulty for the worker to move the moving rod 61 subsequently.

[0034] The support plate 82 is a plate-shaped structure. The support plate 82 is slidably disposed on the side wall of the second C-shaped block 53 near the first C-shaped block 41, and the side wall of the first C-shaped block 41 near the second C-shaped block 53 is provided with a receiving groove 83 that matches the support plate 82.

[0035] When the second C-shaped plate 52 is not subjected to external force, its right side is flush with the right side of the first C-shaped plate 3 under the action of the silicone strip 51. At this time, the worker needs to move both ends of the binding strip into the first C-shaped block 41 and the second C-shaped block 53 respectively, and slide the support plate 82 to connect the support plate 82 with the receiving groove 83, so that the first C-shaped block 41 and the second C-shaped block 53 can move synchronously. At this time, the worker only needs to slide the sliding block 4 to adjust the position of the first C-shaped block 41 and the second C-shaped block 53 at the same time, thereby reducing the difficulty for the worker to match the position of the first C-shaped block 41 and the second C-shaped block 53 with the width of the binding strip.

[0036] The slider 84 is a block structure and is installed on the side wall of the support plate 82 to reduce the difficulty for workers to move the support plate 82.

[0037] The reinforcing rib 9 is set on the side wall of the silicone strip 51 away from the first L-shaped block 42. The reinforcing rib 9 improves the structural strength of the silicone strip 51, thereby increasing the probability that the silicone strip 51 will remain vertical when it is not subjected to external force. This, in turn, increases the probability that the right side of the second C-shaped plate 52 will be flush with the right side of the first C-shaped plate 3 when it is not subjected to external force, thus improving the user experience of the staff.

[0038] The working principle of the seam-sewing device for waterproof sportswear processing in this embodiment is as follows: During the production of sportswear, multiple fabrics need to be spliced ​​and sewn together. Before sewing, the workers need to seam the edges of the fabrics. At this time, the workers need to connect the fixing plate 32 to the operating table 1, align the mounting holes 33 on the fixing plate 32 with the corresponding fixing holes on the operating table 1, and connect the fixing bolts through the mounting holes 33 to the operating table 1. This allows the first C-shaped plate 3 and the fixing plate 32 to remain stable under the action of the fixing bolts.

[0039] Subsequently, the worker needs to fold the binding strip into a C-shape and place it between the first C-shaped block 41 and the two first L-shaped blocks 42 to initially stabilize one end of the binding strip. Next, the worker needs to hold one end of the binding strip and adjust the other end to connect it with the second C-shaped plate 52, thus initially stabilizing the binding strip. Then, the worker needs to slide the sliding block 4 to adjust the positions of the first C-shaped block 41 and the second C-shaped block 53, allowing the first L-shaped block 42 and the second L-shaped block 54 to cooperate and limit the binding strip. Further, the worker needs to rotate the second C-shaped plate 52 to change it from a vertical to a horizontal position. When the second C-shaped plate 52 is stable, the end of the binding strip away from the first C-shaped plate 3 moves with the second C-shaped plate 52 and remains stable, reducing the probability of the worker accidentally touching the binding strip and improving the user experience of the device. Then, the staff only needs to place the fabric to be bound on the presser foot of the sewing machine 21 and turn on the sewing machine 21 to bind the edge of the fabric with the binding strip, thereby reducing the difficulty of operation for the staff.
