Description

Technical Field

[0001] This invention relates to the field of backpack sewing technology, and more particularly to a sewing device for backpacks. Background Technology

[0002] Backpacks are a common type of backpack, widely used in daily life, travel, and outdoor sports. Sewing is a crucial step in backpack manufacturing. Common sewing equipment includes sewing machines, scissors, needles, and thread. These tools play a vital role in cutting, sewing, and decorating the fabric. The main body of a backpack is typically made of multiple pieces of fabric sewn together using a sewing machine. When sewing the main body, it's essential to ensure strong seams and neat stitches to guarantee the backpack's structural stability and aesthetic appeal. The shoulder straps and back straps are also critical for supporting the backpack's weight and require sewing. Special sewing techniques or tools are often used to reinforce the connections between the shoulder straps and back straps, increasing comfort and durability. Furthermore, details such as the bottom of the backpack, zipper openings, and shoulder strap connections require special treatment. Reinforcing these parts with sewing techniques such as double stitching and zigzag stitching can increase the backpack's durability and stability.

[0003] A search revealed Chinese patent application CN2022216358346, which discloses a sewing device for backpacks. The device includes an operating table. A push rod is slidably connected to the top right side of the operating table. A transmission frame is fixedly connected to the left end of the push rod. Several clamping plates are fixedly connected to the inner wall of the bottom end of the transmission frame. A cylinder is fixedly connected to the top of each clamping plate. A connecting seat is fixedly connected to the top of the connecting seat, and a frame is fixedly connected to the top of the connecting seat. By placing an item between the clamping plates and the positioning post, the item is positioned more quickly. Based on the position of the positioned item, the push rod drives the transmission frame to slide forward, and the cylinders drive the clamping plates to quickly clamp or release the item, thus allowing for manipulation of the item. However, the aforementioned backpack sewing device has the following shortcomings:

[0004] While the aforementioned device replaces manual placement of items, providing safety protection for workers, and is simple to operate, thus improving work efficiency, its overall structure occupies a large area, making it difficult to move and causing transportation inconvenience. Furthermore, its spatial mobility is limited. Therefore, there is an urgent need for a convenient sewing device for backpacks. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sewing device for backpacks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sewing device for backpacks includes a workbench and a mounting frame. The four corners of the workbench and the bottom of the mounting frame are bolted with casters. A guide plate is fixedly connected to one outer wall of the workbench. Sliding holes are provided on both sides of the bottom of the mounting frame, with the guide plate slidingly engaging with the sliding holes. Limit plates are bolted to both sides of the front of the mounting frame. A housing is bolted to both sides of the back of the mounting frame, housing a battery. A mounting plate is bolted to one outer wall of the mounting frame, with a push-pull mechanism on one side of the mounting plate. A rectangular guide groove is provided on the outer periphery of the top of the workbench, with a fixing mechanism slidably connected within the groove. A clamp is fixedly connected to the output end of the fixing mechanism. An anti-slip plate is adhered to the center of the top of the workbench. A sewing machine is fixedly connected to the push-pull end of the push-pull mechanism.

[0008] Furthermore, the push-pull mechanism includes a connecting plate, an L-shaped sliding hole, an oblique hole, a sliding plate, a push-pull handle, a limiting ring, a sliding column, and a groove. A guide groove is provided on one side of the mounting plate, and the sliding plate is slidably connected to the guide groove. The groove is provided at the top and bottom of the sliding plate, and the groove is adapted to the inner side of the guide groove. An oblique hole is provided on one side of the sliding plate, and an L-shaped sliding hole is provided in the guide groove.

[0009] Based on the aforementioned scheme: the push-pull handle is fixed to the outer wall of one side of the slide plate by bolts, the sliding post is inserted into the oblique hole and the L-shaped sliding hole, and the sliding post forms a sliding fit with the L-shaped sliding hole and the oblique hole.

[0010] A better embodiment of the aforementioned scheme is that the limiting ring is threaded to one end of the sliding column, the connecting plate is welded to the other end of the sliding column, and the end of the connecting plate is fixedly connected to one side of the sewing machine.

[0011] Pull the slide plate outward from the end of the mounting plate near the mounting bracket by pushing and pulling the handle. At this time, the sliding column located at the bottom of the L-shaped sliding hole and the bottom of the inclined hole moves upward and moves forward along the horizontal position of the L-shaped sliding hole, which drives the sewing machine at the end of the connecting plate to move forward and be placed above the worktable. At this time, place the backpack to be processed on the anti-slip plate on the top of the worktable.

[0012] As a further aspect of the present invention: the bottom outer wall of the mounting frame is fixed with a bearing plate by bolts, and the top outer wall of the bearing plate is fixed with a wireless charging platform by bolts, and a wireless charging plate is provided on the bottom side of the sewing machine.

[0013] Meanwhile, the fixing mechanism includes a base plate, guide post, U-shaped plate, guide plate, guide wheel, fixing ring, inclined surface, screw, fixing plate, moving post, fixing pin, U-shaped groove, guide hole and rotating ring, and the moving post is slidably connected in the rectangular guide groove, the fixing plate is threaded to the top of the moving post, and the screw is rotatably connected to one corner of the top of the fixing plate.

[0014] The rotating ring drives the screw to rotate, and the rotating screw drives the fixed ring at the top to rotate at a certain angle. At this time, the guide wheel rolls up and down on the inclined plane. The rolling guide wheel drives the guide plate to swing. One end of the guide plate pulls the guide post to move vertically up and down in the U-shaped plate, which in turn drives the clamp on one side of the bottom plate of the guide post to press and position the side of the backpack to be processed.

[0015] As a preferred embodiment of the present invention: the swivel is fixedly connected to the circumference of the screw, the fixing ring is threadedly connected to the top circumference of the screw, and the inclined surface is provided on the top circumference of the screw, and an L-shaped plate is welded to the other corner of the top of the fixing plate.

[0016] Meanwhile, the U-shaped plate is fixedly connected to the top side of the L-shaped plate, and the guide post is slidably connected to both ends of the U-shaped plate, and the bottom plate is fixedly connected to the bottom end of the guide post. The middle section of the guide plate is rotatably connected to one side of the L-shaped plate through a rotating shaft.

[0017] Preferably, the guide wheel is rotatably connected to one end of the guide plate, and the guide wheel and the inclined surface form a rolling fit. The guide hole is opened on one side of the guide post, and the fixing pin is inserted into one side of the middle section of the guide hole.

[0018] As a preferred embodiment of the present invention: the U-shaped groove is formed at the other end of the guide plate, and the U-shaped groove and the fixing pin roll against each other, and one side of the base plate is connected to one side of the clamping piece by bolts.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This is a sewing device for backpacks. During operation, the sliding plate is pulled outward from the end of the mounting plate near the mounting frame by pushing and pulling the handle. At this time, the sliding column located at the bottom of the L-shaped sliding hole and the bottom of the oblique hole moves upward and forward along the horizontal position of the L-shaped sliding hole, driving the sewing machine at the end of the connecting plate forward and placing it above the worktable. The backpack to be processed is then placed on the anti-slip plate on the top of the worktable, and the four corners of the backpack are clamped and fixed by the fixing mechanism. Then, the sewing machine is started to sew. When it is necessary to move the whole device, it can be moved by the universal wheels at the bottom of the worktable and the mounting frame, realizing the freedom of movement of the whole device. At the same time, by pulling back the push and pull handle, the sewing machine moves backward and downward simultaneously. At this time, the wireless charging plate at the bottom of the sewing machine is in contact with the wireless charging platform to complete the charging of the sewing machine. Thus, it not only solves the problem of traditional equipment having a large footprint and being difficult to move, but also improves the sewing efficiency and quality of backpacks.

[0021] 2. This backpack sewing device uses a rotating ring to drive a screw, which in turn rotates a fixed ring at its top. Meanwhile, a guide wheel rolls up and down on an inclined plane, causing a guide plate to swing. One end of the guide plate pulls a guide post vertically up and down within a U-shaped plate, which in turn causes a clamping piece on one side of the bottom plate of the guide post to press and position the side of the backpack to be processed. This effectively ensures the accuracy of the backpack sewing, guarantees the quality of the stitching, avoids sewing skewing due to positioning deviation, and improves the stability of backpack sewing. Simultaneously, the moving post can slide and rotate freely within a rectangular guide groove, facilitating the adjustment of the horizontal angle of the clamping piece and expanding the gripping angle of the backpack.

A sewing machine 7 is fixedly connected to the push-pull end of the push-pull mechanism 11.

[0035] To improve the sewing efficiency and quality of backpacks; such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the push-pull mechanism 11 includes a connecting plate 1101, an L-shaped sliding hole 1102, an oblique hole 1103, a sliding plate 1104, a push-pull handle 1105, a limiting ring 1106, a sliding post 1107, and a groove 1108. A guide groove is provided on one side of the mounting plate 8, and the sliding plate 1104 is slidably connected to the guide groove. The groove 1108 is located at the top and bottom of the sliding plate 1104, and the groove 1108 is adapted to the inner side of the guide groove. The oblique hole 1103 is located on one side of the sliding plate 1104. The L-shaped sliding hole 1104... 102 is opened in the guide groove, and the push-pull handle 1105 is fixed to the outer wall of one side of the slide plate 1104 by bolts. The sliding column 1107 is inserted into the inclined hole 1103 and the L-shaped sliding hole 1102, and the sliding column 1107 forms a sliding fit with the L-shaped sliding hole 1102 and the inclined hole 1103. The limiting ring 1106 is connected to one end of the sliding column 1107 by thread. The connecting plate 1101 is welded to the other end of the sliding column 1107, and the end of the connecting plate 1101 is fixedly connected to one side of the sewing machine 7.

[0036] The bottom outer wall of the mounting frame 4 is fixed with a bearing plate 9 by bolts, and the top outer wall of the bearing plate 9 is fixed with a wireless charging platform 10 by bolts. A wireless charging plate is provided on the bottom side of the sewing machine 7. The wireless charging plate and the wireless charging platform 10 are in close contact with each other and achieve power transmission through magnetic resonance coupling.

[0037] During operation, the sliding plate 1104 is pulled outward from the end of the mounting plate 8 near the mounting bracket 4 by pushing and pulling the handle 1105. At this time, the sliding column 1107 located at the bottom of the L-shaped sliding hole 1102 and the bottom of the oblique hole 1103 moves upward, and the sliding column 1107 moves forward along the horizontal position of the L-shaped sliding hole 1102, driving the sewing machine 7 at the end of the connecting plate 1101 to move forward and be placed above the workbench 2. At this time, the backpack to be processed is placed on the anti-slip plate 12 on the top of the workbench 2, and the four corners of the backpack are clamped and fixed by the fixing mechanism 3 using the clips 15. Then, the sewing machine 7 is started to sew. When the whole device needs to be moved, it can be moved by the casters 1 at the bottom of the workbench 2 and the mounting frame 4, realizing the freedom of movement of the whole device. At the same time, by pulling back the push handle 1105, the sewing machine 7 moves backward and downward. At this time, the wireless charging plate at the bottom of the sewing machine 7 is in contact with the wireless charging platform 10, completing the charging of the sewing machine 7. Thus, not only is the problem of traditional equipment taking up a large area and being difficult to move solved, but the sewing efficiency and quality of the backpack are also improved.

[0038] To facilitate the positioning and fixation of the backpacks to be processed; such as Figure 5 and Figure 6As shown, the fixing mechanism 3 includes a base plate 301, a guide post 302, a U-shaped plate 303, a guide plate 304, a guide wheel 305, a fixing ring 306, an inclined surface 307, a screw 308, a fixing plate 309, a moving post 310, a fixing pin 311, a U-shaped groove 312, a guide hole 313, and a rotating ring 314. The moving post 310 is slidably connected to the rectangular guide groove 13. The fixing plate 309 is threaded to the top of the moving post 310. The screw 308 is rotatably connected to one corner of the top of the fixing plate 309. The rotating ring 314 is fixedly connected to the circumference of the screw 308. The fixing ring 306 is threaded to the top circumference of the screw 308. The inclined surface 307 is provided on the top circumference of the screw 308. An L-shaped plate is welded to the other corner of the top of 9. A U-shaped plate 303 is fixedly connected to the top side of the L-shaped plate, and a guide post 302 is slidably connected to both ends of the U-shape of the U-shaped plate 303.

At the same time, the moving post 310 can slide and rotate freely in the rectangular guide groove 13, which promotes the adjustment of the horizontal angle of the clamping piece 15 and expands the angle of backpack clamping.

[0040] In this embodiment, the sliding plate 1104 is pulled outward from the end of the mounting plate 8 near the mounting bracket 4 by pushing and pulling the handle 1105. At this time, the sliding column 1107 located at the bottom of the L-shaped sliding hole 1102 and the bottom of the inclined hole 1103 moves upward and moves forward along the horizontal position of the L-shaped sliding hole 1102, which drives the sewing machine 7 at the end of the connecting plate 1101 to move forward and be placed above the workbench 2. At this time, the backpack to be processed is placed on the anti-slip plate 12 on the top of the workbench 2.

[0041] The rotating ring 314 drives the screw 308 to rotate, and the rotating screw 308 drives the fixed ring 306 at its top to rotate at a certain angle. At this time, the guide wheel 305 rolls up and down on the inclined plane 307. The rolling guide wheel 305 drives the guide plate 304 to swing. One end of the guide plate 304 pulls the guide post 302 to move vertically up and down in the U-shaped plate 303, which in turn drives the clamping piece 15 on one side of the bottom plate 301 at the bottom end of the guide post 302 to press and position the side of the backpack to be processed.

[0042] Subsequently, the sewing machine 7 is started to perform sewing work. When it is necessary to move the entire device, it can be moved by the casters 1 at the bottom of the worktable 2 and the mounting frame 4, realizing the freedom of movement of the entire device. At the same time, by pulling back the push-pull handle 1105, the sewing machine 7 moves backward and downward simultaneously. At this time, the wireless charging plate at the bottom of the sewing machine 7 is in contact with the wireless charging platform 10, completing the charging of the sewing machine 7.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
