Description

Technical Field

[0001] This invention relates to the field of water-resistant clothing sewing, specifically to a sewing device and method for using water-resistant clothing. Background Technology

[0002] Wading means stepping into water, wading into rivers, oceans, and other bodies of water. With economic development, agriculture and industry require water-related work, some of which requires manual labor. However, prolonged immersion in water can easily lead to skin damage and may cause disease infection due to unsanitary water sources. Therefore, a wading suit is needed to isolate workers from the external water source and protect their bodies when they are working in the water.

[0003] Existing water-resistant clothing mainly uses PVC as its primary material. PVC has excellent water-repellent properties, and it does not peel or age after being submerged in water. At the same time, PVC is lightweight and inexpensive, resulting in low manufacturing costs. Because water-resistant clothing needs to be sealed to effectively prevent water from entering, the PVC fabric is typically sewn together using a sewing machine. After sewing, the fabric joints are then heat-pressed through a heat treatment process to secure the connection.

[0004] However, current water-resistant clothing uses PVC as its main material. Because PVC is harder than common fabrics, sewing machine needles require more force to pierce it, resulting in a shorter machine lifespan. Furthermore, due to the hardness of PVC, the sewing thread cannot effectively tighten the fabric during stitching. Additionally, after sewing, perforations remain in the fabric, requiring heat sealing. Current production methods typically involve using an additional heat-pressing plate to heat-press the fabric, with manual assistance. However, the high temperatures required for heat-pressing PVC can cause burns to the user while assisting with fabric movement. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a sewing device and method for using a water-resistant garment, in order to solve the technical problems of current water-resistant garments, which use PVC as the main material. However, because PVC is harder than common fabrics, it requires more force to pierce through when sewing with a common sewing machine needle, resulting in a shorter machine lifespan. Furthermore, because PVC is harder, the sewing thread cannot effectively tighten the PVC fabric during sewing. In addition, because there are still perforations in the fabric after sewing, heat pressing is required to seal the perforations. Existing production methods generally use an additional heat press plate to heat press the fabric, with manual assistance. However, because heat pressing PVC fabric requires high temperatures, it may cause burns to the user when assisting in the movement of the fabric.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sewing device and method for using a water-resistant garment, comprising a tooling plate, a sewing machine body disposed on the tooling plate, a first support column and a second support column symmetrically disposed on the sewing machine head of the sewing machine body, a needle disposed on the end of the first support column away from the sewing machine body, a connecting rod disposed on the first support column at the connection point with the needle, a heat-pressing structure disposed on the end of the connecting rod away from the first support column, a pressing element disposed on the end of the first support column away from the sewing machine body, a top plate disposed on the first support column, and the sewing machine body... Near the threaded shaft, a slot is provided on the sewing machine body. A threaded barrel is rotatably mounted on the top of the slot, and the threaded shaft extends into the threaded barrel. A first rotating shaft is provided on one side of the threaded barrel in the slot. A control device is provided on the first rotating shaft and the slot. The first rotating shaft extends outside the sewing machine body and extends outward through the control device to outside the slot. A second rotating shaft is provided outside the sewing machine body, cooperating with the first rotating shaft. A transmission track is fitted on the second rotating shaft, and the other end of the transmission track is connected to a preheating structure mounted on a tooling plate.

[0007] By adopting the above technical solution, through the set hot-pressing structure and preheating structure, the PVC fabric is softened before sewing the water-resistant clothing, making it easier for the knitting needles to pass through and extending the service life of the device. After the sewing is completed, the set hot-pressing structure is used to heat-press the joint of the PVC fabric, so that the PVC fabric is more tightly connected and waterproof.

[0008] The invention is further configured such that the control device includes an airbag, which is disposed on one side near the top plate. An air supply pipe is disposed in the slot in conjunction with the airbag, and the air supply pipe extends into the sewing machine body on one side of the first rotating shaft. A sliding groove is provided on the sewing machine body in conjunction with the first rotating shaft, and the sliding groove is connected to the inside of the slot. A cylinder structure is disposed in the sliding groove on the side away from the threaded barrel. A connecting block is disposed on the side of the cylinder structure near the threaded barrel. The connecting block is rotatably connected to the first rotating shaft. A second spring is disposed on the side of the connecting block away from the cylinder structure.

[0009] By adopting the above technical solution and through the set control device, when the first support column moves upward, it drives the top plate set on the first support column to squeeze the air bag set on the sewing machine main body, so that the gas in the air bag enters the cylinder structure through the air supply pipe, thereby causing the cylinder structure to push the connecting block to move, so that the first rotating shaft contacts the threaded barrel. At the same time, the threaded shaft is pushed upward to cooperate with the rotating threaded barrel, causing the first rotating shaft to rotate. When the first support column moves downward, under the action of the second spring, the connecting block resets and no longer contacts the threaded barrel.

[0010] The present invention is further configured such that the preheating structure includes a limiting block, the limiting block is a hollow structure, the limiting block is disposed on a tooling plate located below the first rotating shaft, a fourth rotating shaft is rotatably disposed inside the limiting block, one end of the fourth rotating shaft extends out of the limiting block and connects to the transmission track, a partition block is disposed at the bottom of the limiting block and connects to the tooling plate, a first transmission belt and a second transmission belt are respectively disposed on both sides of the partition block inside the limiting block, the first transmission belt and the second transmission belt are in contact with the fourth rotating shaft, and a second heating block is disposed on one side of the fourth rotating shaft inside the limiting block.

[0011] By adopting the above technical solution, the rotation of the first rotating shaft drives the transmission track to rotate, which in turn drives the fourth rotating shaft to rotate. This causes the fourth rotating shaft to drive the first and second transmission belts in contact with it to rotate, thereby moving the fabric. At the same time, the second heating block set in the limiting block heats the transmission belt, thereby preheating the fabric.

[0012] The invention is further configured such that a fixing member is provided on the sewing machine body in conjunction with the second rotating shaft, the second rotating shaft extends to the top of the other end of the tooling plate, and a support frame is provided on the tooling plate in conjunction with the second rotating shaft.

[0013] By adopting the above technical solution, the second rotating shaft is supported by the set fixing parts and the set support frame, thereby ensuring the normal operation of the whole device.

[0014] The invention is further configured such that the hot-pressing structure includes a clamping block connected to a connecting rod; a support block is provided on the tooling plate in conjunction with the clamping block; a connector is provided on the side of the clamping block near the support block; connecting columns are symmetrically arranged on the side of the connector near the support block; a third rotating shaft is rotatably arranged on the connecting column; a roller is rotatably arranged on the third rotating shaft; a first heating block is provided on the side of the connector near the support block; the first heating block is disposed between a pair of connecting columns; the connecting column extends into the connector; a first spring is provided inside the connector in conjunction with it; and a guide block is provided on the side of the support block near the first support column.

[0015] By adopting the above technical solution, when the first support column moves upward, the rollers press against the fabric under the action of the first spring to fix it to a certain extent. When the first support column moves downward, the connecting column squeezes the first spring inward, causing the rollers to retract into the connecting piece, thereby allowing the second heating block set on the connecting piece to heat press the PVC fabric.

[0016] The present invention is further configured such that a curved guide is provided on the side of the separator block near the first support column, and the curved guide has a gradual structure from flat to vertical.

[0017] The invention is further configured such that the fabric of the set partition block and the set curved guide will become a symmetrical vertical design, thereby facilitating subsequent processing.

[0018] The present invention also provides a method for using a sewing device for a water-resistant garment, the specific steps of which are as follows:

[0019] Step 1: Place the two pieces of fabric used to make the wading suit on either side of the divider;

[0020] Step 2: The main body of the sewing machine is working. The up and down movement of the first support column triggers the control device, causing the first and second transmission belts to rotate and pull the fabric to move. After passing through the preheating structure, the fabric is heated and softened.

[0021] Step 3: The fabric continues to move past the curved guide, and then, with manual assistance, it is pressed to present a three-layer structure.

[0022] Step 4: The fabric is limited by the clamping device, and the needle sews the superimposed fabric. As the fabric softens due to heat, the threads will be trapped inside the fabric.

[0023] Step 5: After the fabric is sewn, continue to move it to the support block via the guide block. The sewn fabric is then heat-pressed through the heat-pressing structure to seal the needle holes in the fabric.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] 1. This invention utilizes a top plate mounted on a first support column. When the first support column moves upward, it compresses an air bladder, causing gas inside the air bladder to enter the cylinder structure through an air supply pipe. This cylinder structure then pushes the connecting block, bringing the first rotating shaft into contact with the threaded barrel. Simultaneously, the top plate compresses the threaded shaft, causing it to move upward and rotate within the threaded barrel. This rotation of the movable threaded barrel drives the first rotating shaft to rotate. The rotation of the first rotating shaft then drives the fourth rotating shaft at the bottom, which in turn drives the first and second transmission belts to move. The movement of the belt causes the fabric to move, and the heating block inside the limiting block heats and softens the PVC fabric, making it easier for the needle to pass through. After sewing, the sewn fabric is pushed under the pressing block by the drive belt. At this time, the up and down movement of the first support column causes the second heating block below the pressing block to directly heat press the fabric, thereby closing the needle holes at the sewn part of the fabric to prevent water from entering. The preheating structure softens the fabric, allowing the sewn threads to be inserted into the fabric, making the fabric connection tighter.

[0026] 2. This invention uses a curved guide on one side of the partition block. After the fabric is preheated and softened, it is pushed by the transmission belt through the surface of the curved guide, thus gradually changing from a flat position to a vertical position. At this time, by manually pressing it to one side, the fabric presents a three-layer structure. Then, it is sewn and heat-pressed to achieve a better connection effect and waterproof effect.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of the present invention will now be described.

[0042] This invention is a sewing device designed for sewing water-resistant clothing. Since the water-resistant clothing is made of PVC material, after shaping and sewing, it is necessary to seal the needle holes with heat to ensure its waterproofness. Therefore, a preheating structure and a heat-pressing structure are added to the existing sewing machine body 2.

[0043] Specifically, the sewing device used for water-resistant clothing, such as Figure 1 As shown, the sewing machine includes a tooling plate 1, on which a sewing machine body 2 is mounted. One end of the sewing machine body 2 is fixedly mounted on the tooling plate 1 as the main structure of the sewing machine, while the other end is a distance away from the tooling plate 1 and serves as the machine head. A first support column 3 and a second support column 12 are symmetrically arranged on the machine head. The first support column 3 extends above the tooling plate 1 and is connected to a needle 30. The second support column 12 extends above the tooling plate 1 and is connected to a clamping member 4. The clamping member 4 is U-shaped in conjunction with the needle 30, so that the fabric can be fixed to a certain extent while being sewn, preventing it from shifting.

[0044] Because PVC is a common material for water-resistant clothing, and although it has a certain degree of softness, it is relatively stiff compared to traditional fabrics. When sewing PVC fabric with a sewing machine, more force is needed to pierce it, which results in a short service life for the needle 30. To address this, this device provides a preheating structure that can preheat the PVC fabric, making it easier for the needle 30 to sew it.

[0045] For details, please refer to Figure 1 , Figure 7 , Figure 8 As shown, the preheating structure includes a limiting block 10, which is disposed on the tooling plate 1 at a position parallel to the needle 30. The limiting block 10 is a hollow structure, and a partition block 105 is provided at the bottom of the limiting block 10. The limiting block 10 is connected to the tooling plate 1 through the partition block 105. A first transmission belt 103 and a second transmission belt 104 are respectively provided on both sides of the partition block 105 at the bottom of the limiting block 10. The limiting block 10 has grooves that cooperate with the first transmission belt 103 and the second transmission belt 104. The limiting block 10 is located within the grooves of the first transmission belt 103 and the second transmission belt 104. A fourth rotating shaft 102 is arranged above the two transmission belts 104 and is in contact with them. The fourth rotating shaft 102 extends to the outside of the limiting block 10 and is connected to the control structure. The fourth rotating shaft 102 is controlled by the control structure. A second heating block 101 is arranged inside the limiting block 10 on one side of the fourth rotating shaft 102. The second heating block 101 heats the PVC fabric, softening it and making it easier to sew the fabric later. The preheating structure softens the fabric, allowing the sewing threads to be inserted into the fabric, making the fabric connection tighter.

[0046] Further reference Figure 2-4 As shown, the control structure includes a top plate 19, which is mounted on the first support column 3. During normal operation, the sewing machine moves the needle 30 up and down via the up-and-down movement of the first support column 3, thus sewing the fabric. For this purpose, an airbag 20 and a threaded shaft 17 are mounted on the sewing machine head near the top plate 19. A slot 13 is formed inside the sewing machine body 2, and the threaded shaft 17 extends into the slot 13. A threaded barrel 16 is mounted inside the slot 13, rotatably positioned on top of the slot 13. A first rotating shaft 7 is located on one side of the threaded barrel 16 within the slot 13, with one end extending outside the sewing machine body 2. The sewing machine body 2 and the slot... The inner quota and the second rotating shaft 8 are provided with a pair of sliding grooves. A connecting block 18 is slidably arranged in the pair of sliding grooves. The connecting block 18 is rotatably arranged with the first rotating shaft 7. A cylinder structure 27 is provided on the side of the connecting block 18 away from the threaded barrel 16 in the sliding groove. The cylinder structure 27 is connected to one end of the air supply pipe 15. The other end of the air supply pipe 15 passes through the sewing machine body 2 and is connected to the air bag 20. When the air bag 20 is squeezed, the cylinder structure 27 can be pushed out, thereby pushing the connecting block 18 a certain distance. A second spring 28 is provided on the side of the connecting block 18 away from the cylinder structure 27 in the sliding groove. When the first support column 3 drives the top plate 19 to move down and no longer squeezes the air bag 20, the connecting block 18 is pushed open by the second spring 28, thereby making the first rotating shaft 7 no longer contact the threaded barrel 16.

[0047] The first rotating shaft 7 extends to one end outside the sewing machine body 2 and is fitted with a second rotating shaft 8. One end of the second rotating shaft 8 extends above the other end of the tooling plate 1. A support frame 9 is fitted on the tooling plate 1 to support the second rotating shaft 8. A support member is fitted on the sewing machine body 2 to assist in supporting the second rotating shaft 8. A transmission track 11 is fitted on the second rotating shaft 8. The other end of the transmission track 11 contacts the fourth rotating shaft 102. Thus, through the control device, when the first support column 3 is raised, the first rotating shaft 7 contacts the threaded barrel 16. Under the transmission of the transmission track 11, the fourth rotating shaft 102 rotates, thereby driving the first transmission belt 103 and the second transmission belt 104, which are in contact with the fourth rotating shaft 102, to rotate inside the limiting block 10. This, in turn, propels and guides the PVC fabric at the bottom of the limiting block 10.

[0048] Because sewing PVC fabric with needle 30 leaves holes on the fabric surface, the water-resistant clothing will leak when used, making it unusable. To address this, this device also provides a heat-pressing structure to heat-press the sewn PVC fabric, closing the holes and preventing the water-resistant clothing from leaking during use.

[0049] For details, please refer to Figure 3 , Figure 5 , Figure 6The hot-pressing structure includes a connecting rod 31, which is located at the connection between the first support column 3 and the needle 30 and extends away from the second support column 12. A clamping block 5 is located at the bottom of the other end of the connecting rod 31. A support block 24 is mounted on the tooling plate 1 to cooperate with the clamping block 5. A guide block 14 is located on the side of the support block 24 near the needle 30. The guide block 14 allows the fabric to be pushed under the connector 6. A connector 6 is located on the side of the clamping block 5 near the support block 24. A pair of connecting columns 26 are symmetrically arranged on the side of the connector 6 near the support block 24. A third rotating shaft 21 is rotatably mounted on the connecting column 26, and a roller 23 is rotatably mounted on the third rotating shaft 21. The roller 23 contacts the support block 24. The other end of the connecting column 26 extends to the connecting... Inside component 6, a T-slot is provided to cooperate with connecting post 26 and roller 23. A first spring 25 is provided in the T-slot. Connecting post 26 is connected to the first spring 25. A first heating block 22 is provided between a pair of connecting posts 26. When the first support post 3 is raised, the connecting post 26 fixes the fabric on the support block 24 under the action of the first spring 25. However, when the fabric is pushed, the roller 23 rotates and can drive the fabric to move. When the first support post 3 is lowered, the connecting component 6 is pressed downward, thereby squeezing the connecting post 26 and causing the connecting post 26 and roller 23 to be drawn into the T-slot on the connecting component 6. At this time, the first heating block 22 on the connecting component 6 squeezes the sewn PVC fabric, thereby achieving the effect of heat-pressing to seal the needle holes.

[0050] Based on the above structure, refer to Figure 11 The partition block 105 is provided with a curved guide 29 on the side near the first support column 3. The curved guide 29 is designed to have a structure that gradually transforms from a plane to a vertical surface. This allows the fabric to stand up while it moves, and then be adjusted manually and sewn by needle 30.

[0051] Further reference Figure 9 In this device, the fabric is stacked in a three-layer structure with manual assistance. Compared with the traditional two-layer stacking of fabric, this stacking method has better connection strength and waterproof performance after sewing and heat pressing.

[0052] Instructions for use: Before use, power on the device to heat the first heating block 22 and the second heating block 101. The first support column 3 will begin to move up and down. After preheating, push the two pieces of PVC fabric to be sewn forward through the two sides of the separator 105. When the fabric reaches the bottom of the first transmission belt 103 and the second transmission belt 104, the top plate 19 squeezes the airbag 20, causing the cylinder structure 27 to push out the connecting block 18, making the first rotating shaft 7 contact the threaded barrel 16. At the same time, the top plate 19 squeezes the threaded shaft 17. With the cooperation of the threaded shaft 17 and the threaded barrel 16, the threaded barrel 16 rotates, thereby driving the first rotating shaft 7 to contact the threaded barrel 16. When the first rotating shaft 7 rotates, and the first support column 3 moves downward, it loses its compression on the airbag 20. Under the action of the second spring 28, it pushes the connecting block 18 away, so that the first rotating shaft 7 no longer contacts the threaded barrel 16. This allows the first support column 3 to move upward each time, causing the first rotating shaft 7 to rotate a certain distance in one direction. The rotation of the first rotating shaft 7 drives the second rotating shaft 8 to rotate. Under the action of the transmission track 11, the fourth rotating shaft 102 rotates, which in turn causes the first transmission belt 103 and the second transmission belt 104 to rotate, thereby guiding the PVC fabric forward. After passing the limit block 10, the curved guide 29 transforms the fabric into... Figure 12 The fabric is then transformed into the state shown in the image, with manual assistance. Figure 9 The three-layer structure shown is then sewn together with needle 30. After the fabric is sewn, it enters the heat-pressing structure. The first heating block 22 heats and presses the fabric to seal the holes caused by sewing, thereby ensuring the waterproofness of the wading suit.
