Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically a positioning sewing device for garment production. Background Technology

[0002] According to their purpose, sewing machines can be divided into household sewing machines, industrial sewing machines, and service industry sewing machines that fall between the two; according to their drive method, they can be divided into hand-cranked, foot-operated, and electric sewing machines; according to the stitches they sew, they can be divided into sewing machines with imitation hand-sewing stitches, lockstitch, single-thread chain stitch, double-thread or multi-thread chain stitch, single-thread or multi-thread overlock chain stitch, and multi-thread cover chain stitch.

[0003] Publication No. CN216738841U discloses a novel high-efficiency industrial garment sewing machine. This device achieves the limiting and fixing effect of the extension table through a connector, folding head, connecting tube, knobs, and an extension platform. When the extension table needs to be used, it is pulled upwards until it is level with the operating table. At this time, the extension table drives the folding head to rotate inside the connector. After the extension table is level with the operating table, two knobs are rotated, causing each of the two folding heads to rotate. The two folding heads then drive the two connecting tubes to rotate until the bending points of the folding heads and connectors change from a vertical to a horizontal position. At this point, the folding heads and connectors can no longer change angle vertically, and due to the limitation of the extension table being level with the operating table, they cannot rotate horizontally either. This achieves the limiting and fixing effect of the extension table. However, this patent still has the following problems in actual use:

[0004] The device achieves the limiting and fixing effect of the extension platform through connectors, folding heads, connecting tubes, knobs, and extension platforms. However, the device lacks a limiting structure, which requires workers to constantly adjust the fabric position when sewing longer garments, greatly reducing the device's efficiency and causing inconvenience to workers.

[0005] A positioning sewing device for garment production is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning sewing device for garment production, in order to solve the problem mentioned in the background art that the current device achieves the limiting and fixing effect of the extension table by means of connectors, folds, connecting tubes, knobs, extension tables, etc., thereby achieving the limiting and fixing effect of the extension table. However, the device does not have a limiting structure, which means that when workers sew long garments, they need to constantly adjust the position of the fabric, thus greatly reducing the efficiency of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a positioning sewing device for garment production, comprising a workbench, wherein a sewing machine body is provided on one side of the top of the workbench; a limiting mechanism is provided on one side of the top of the workbench, and a fixing component is provided inside the limiting mechanism;

[0008] The limiting mechanism includes a support plate disposed on one side of the top of the worktable, a rotating plate disposed on the top of the support plate, a groove formed at the bottom of the rotating plate, a rotating shaft rotatably connected to the upper interior of the support plate, both ends of the rotating shaft passing through the rotating plate and fixedly connected to the rotating plate, fixed rods symmetrically slidably connected inside the rotating plate, a pressing plate fixedly connected between the bottom of the fixed rods, and ball bearings rollingly connected to the lower interior of the pressing plate, a first contraction spring sleeved on the outside of the fixed rods, a pull ring fixedly connected between the top of the fixed rods, a gear fixedly installed at one end of the rotating shaft, an installation groove formed on one side of the support plate, a toothed plate slidably connected inside the installation groove, contraction rods symmetrically fixedly installed between the inner side of the installation groove and the toothed plate, and a second contraction spring sleeved on the outside of the contraction rods.

[0009] Preferably, a support rod is symmetrically fixedly installed on the top of the extrusion plate, and the top of the support rod passes through the rotating plate and is slidably connected to the rotating plate, and a stop block is fixedly installed on the top of the support rod.

[0010] Preferably, a fixing plate is fixedly installed at the bottom of the support plate, and a cabinet is fixedly installed on one side of the fixing plate, and drawers are slidably connected inside one side of the cabinet.

[0011] Preferably, the fixing component includes a positioning plate fixedly installed on one side of the support plate, and a positioning groove is provided on the top side of the worktable, and the positioning plate is inserted into the positioning groove. A limit box is embedded on the top side of the worktable, and a screw is rotatably connected to the bottom inner side of the limit box. A movable frame is threadedly connected to the outside of the screw. An insert plate is slidably connected to the upper inner side of the limit box, and a movable rod is rotatably connected between the movable frame and the insert plate. A slot is provided on the bottom side of the positioning plate, and the insert plate is inserted into the slot.

[0012] Preferably, a telescopic rod is fixedly installed between the movable frame and the inner side of the limiting box, and a third retraction spring is sleeved on the outside of the telescopic rod.

[0013] Preferably, the teeth on the top of the toothed plate are meshed with the gear.

[0014] Preferably, the outer side of the support plate is fitted and connected to the inner side of the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A positioning sewing device for garment production is described, in detail, as follows: An operator rotates a rotating plate on top of a support plate. The rotation of the rotating plate drives the rotation of the pressing plate. At this time, multiple sets of ball bearings at the bottom of the pressing plate contact the worktable surface. The operator then pulls the toothed plate to slide within the mounting groove. This causes the contraction rod and the second contraction spring to contract. The tension generated by the second contraction spring allows the teeth on the top of the toothed plate to mesh with the gear. The contractile property of the first contraction spring allows the pressing plate to move downwards quickly. At this time, the multiple sets of ball bearings press against the fabric surface, thereby achieving the effect of quickly fixing and limiting the fabric. Furthermore, it allows for flexible adjustment based on the subsequent fabric movement. This design effectively avoids the need for constant adjustments when sewing longer fabrics, significantly reducing wrinkles and improving sewing quality. The mechanism works by rotating a screw to move the movable frame, which in turn extends and resets the telescopic rod and the third contraction spring. The rotation of the movable rod pushes the insert plate to slide inside the limit box, allowing it to connect with the slot. This enables quick installation and removal of the support plate, facilitating flexible assembly of the rotating plate. This greatly improves the flexibility of the device and makes subsequent inspection and maintenance of the limit mechanism easier.

[0016] 1. The operator rotates the rotating plate on top of the support plate. This rotation drives the rotating shaft, which in turn rotates the extrusion plate. Multiple sets of ball bearings at the bottom of the extrusion plate contact the worktable surface. The operator then pulls the toothed plate, causing it to slide within the mounting groove. This retracts the retraction rod and the second retraction spring. Releasing the toothed plate utilizes the tension generated by the second retraction spring, allowing the teeth on the top of the toothed plate to mesh with the gear, thus limiting the angle of the rotating plate. The operator then places the fabric on top of the worktable and pulls the pull ring, moving the two sets of fixed rods. This extends the first retraction spring, and the movement of the fixed rods moves the extrusion plate. Releasing the pull ring again, since the two ends of the first retraction spring are fixedly connected to the pull ring and the rotating plate respectively... Then, by utilizing the contractile property of the first compression spring, the extrusion plate can be moved down quickly. At this time, multiple sets of ball bearings squeeze the fabric surface. Meanwhile, the worker slowly pushes the fabric, and the ball bearings roll on the top of the fabric. The worker then operates the sewing machine to sew the fabric stably, thereby achieving the effect of quickly fixing and limiting the fabric. It also allows for flexible adjustment based on the subsequent fabric movement, effectively avoiding the need for constant adjustments when sewing longer fabrics. This greatly reduces wrinkles and other issues that may occur when sewing longer fabrics, significantly improving the sewing quality of garment fabrics and providing convenience for workers. The worker can also rotate and limit the extrusion plate away from the worktable, making it easier to place excess fabric on the extrusion plate.

[0017] 2. The support plate is initially fixed by inserting the positioning plate into the positioning slot. Then, the operator rotates the screw to move the moving frame. The movement of the moving frame causes the extension rod and the third retraction spring to extend and return to their original positions. When the moving frame moves, it drives the movable rod to rotate. The rotation of the movable rod pushes the insert plate to slide inside the limit box, thereby allowing the insert plate to be inserted into the slot. This enables the quick installation and removal of the support plate, and allows the operator to flexibly assemble the rotating plate. This greatly improves the flexibility of the device during use and facilitates subsequent inspection and maintenance of the limit mechanism, bringing convenience to the operator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a positioning sewing device for garment production, including a workbench 1, a sewing machine body 101 is provided on one side of the top of the workbench 1; a limiting mechanism 2 is provided on one side of the top of the workbench 1, and a fixing component 3 is provided inside the limiting mechanism 2.

[0026] The limiting mechanism 2 includes a support plate 201 disposed on one side of the top of the workbench 1, a rotating plate 202 disposed on the top of the support plate 201, and a groove 203 formed at the bottom of the rotating plate 202. The outside of the support plate 201 is fitted and connected to the inside of the groove 203. A rotating shaft 204 is rotatably connected to the upper inside of the support plate 201, and both ends of the rotating shaft 204 pass through the rotating plate 202 and are fixedly connected to it. Fixed rods 205 are symmetrically slidably connected inside the rotating plate 202. A pressing plate 206 is fixedly connected between the bottom of the fixed rods 205, and ball bearings 207 are rolledly connected to the lower inside of the pressing plate 206. A first contraction spring 208 is sleeved on the outside of the fixed rods 205, and a pull ring 209 is fixedly connected between the top of the fixed rods 205. A gear 210 is fixedly installed at one end of the rotating shaft 204. A mounting groove 211 is provided on one side of the 1, and a toothed plate 212 is slidably connected inside the mounting groove 211.

A shrinking rod 213 is symmetrically fixedly installed between the inner side of the mounting groove 211 and the toothed plate 212. A second shrinking spring 214 is sleeved on the outside of the shrinking rod 213. This can achieve the effect of quickly fixing and limiting the fabric, and can be flexibly adjusted according to the subsequent movement of the fabric. This can effectively avoid the phenomenon that workers need to constantly adjust when sewing long fabrics, thereby greatly reducing the phenomenon of wrinkles and other issues that occur during the sewing of long fabrics, and thus greatly improving the sewing quality of clothing fabrics. This brings convenience to workers when using the device. Workers can also rotate the rotating plate 202 away from the worktable 1 and limit it, so that workers can place excess fabric on the extrusion plate 206.

[0027] Support rods 215 are symmetrically fixedly installed on the top of the extrusion plate 206, and the top of the support rods 215 passes through the rotating plate 202 and is slidably connected to the rotating plate 202. A stop block 216 is fixedly installed on the top of the support rods 215. When the extrusion plate 206 moves, it drives multiple sets of support rods 215 to slide inside the rotating plate 202, thereby achieving the effect of guiding the extrusion plate 206. The design of the stop block 216 can effectively prevent the support rods 215 from falling off. A fixing plate 217 is fixedly installed on the bottom of the support plate 201, and a cabinet 218 is fixedly installed on one side of the fixing plate 217. Drawers 219 are slidably connected inside one side of the cabinet 218. The cooperation between the drawers 219 and the cabinet 218 makes it convenient for workers to store sewing tools, bringing convenience to workers when using them.

[0028] The fixing component 3 includes a positioning plate 301 fixedly installed on one side of the support plate 201, and a positioning groove 302 is provided on one side of the top of the workbench 1. The positioning plate 301 is inserted into the positioning groove 302. A limit box 303 is embedded in one side of the top of the workbench 1. A screw 304 is rotatably connected to the inner bottom of the limit box 303. A movable frame 305 is threadedly connected to the outer side of the screw 304. An insert plate 306 is slidably connected to the upper interior of the limit box 303. A movable rod 307 is rotatably connected between the movable frame 305 and the insert plate 306. The bottom of the positioning plate 301 has a... There is a slot 308, and the insertion plate 306 is inserted into the slot 308. A telescopic rod 309 is fixedly installed between the moving frame 305 and the inner side of the limit box 303, and a third retraction spring 310 is sleeved on the outside of the telescopic rod 309. This enables the quick installation and disassembly of the support plate 201, and facilitates the flexible assembly of the rotating plate 202 by the staff. This allows the staff to use the device according to the actual situation, greatly improving the flexibility of the device during use and facilitating the subsequent inspection and maintenance of the limit mechanism 2 by the staff, bringing convenience to the staff during use.

[0029] Working principle: Before using this positioning sewing device for garment production, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5As shown, the operator rotates the rotating plate 202 on top of the support plate 201. This rotation drives the rotating shaft 204 to rotate, which is located inside the top of the support plate 201. The rotation of the rotating plate 202 causes the extrusion plate 206 to rotate. At this time, multiple sets of ball bearings 207 at the bottom of the extrusion plate 206 contact the surface of the worktable 1. Then, the operator pulls the toothed plate 212 to slide it inside the mounting groove 211. This causes the retraction rod 213 and the second retraction spring 214 to retract. By releasing the toothed plate 212, the tension generated by the second retraction spring 214 allows the... The teeth on the top of the toothed plate 212 mesh with the gear 210, achieving the effect of limiting the angle of the rotating plate 202. Then, the worker places the fabric on the top of the workbench 1. At this time, the worker pulls the pull ring 209, causing the two sets of fixed rods 205 to move. The first contraction spring 208 extends, and the movement of the fixed rods 205 causes the pressing plate 206 to move. The worker then releases the pull ring 209. Since the two ends of the first contraction spring 208 are fixedly connected to the pull ring 209 and the rotating plate 202 respectively, the contractile property of the first contraction spring 208 allows the pressing plate 206 to move. 06. Rapid downward movement: At this time, multiple sets of ball bearings 207 compress the fabric surface. Simultaneously, the worker slowly pushes the fabric forward. The ball bearings 207 roll on top of the fabric, and the worker operates the sewing machine body 101 to stably sew the fabric. This achieves the effect of quickly fixing and limiting the fabric position, and allows for flexible adjustment based on the subsequent fabric movement. This effectively avoids the need for constant adjustments when sewing longer fabrics, significantly reducing wrinkles and other issues during sewing, thus greatly improving the quality of garment fabric sewing and providing a better experience for workers. This provides convenience, allowing staff to rotate the rotating plate 202 away from the workbench 1 and limit its movement. This makes it easier for staff to place excess fabric on the pressing plate 206. When the pressing plate 206 moves, it causes multiple sets of support rods 215 to slide inside the rotating plate 202, thus guiding the pressing plate 206. The design of the stop block 216 effectively prevents the support rods 215 from falling off. The cooperation between the drawer 219 and the cabinet 218 facilitates the storage of sewing tools, bringing convenience to staff during use.

[0030] The support plate 201 is initially fixed by inserting the positioning plate 301 into the positioning slot 302. Then, the operator rotates the screw 304 to move the moving frame 305. The movement of the moving frame 305 causes the telescopic rod 309 and the third retraction spring 310 to extend and return to their original positions. When the moving frame 305 moves, it drives the movable rod 307 to rotate. The rotation of the movable rod 307 pushes the insert plate 306 to slide inside the limit box 303, thereby allowing the insert plate 306 to be inserted into the slot 308. This enables the quick installation and removal of the support plate 201, and facilitates the flexible assembly of the rotating plate 202 by the operator. This greatly improves the flexibility of the device during use and facilitates the subsequent inspection and maintenance of the limit mechanism 2, bringing convenience to the operator during use.
