Description

Technical Field

[0001] This utility model relates to a sewing device for webbing, and more particularly to a sewing machine for heat-pressed braided webbing. Background Technology

[0002] In the garment manufacturing industry, it is often necessary to sew strips of webbing into loops before attaching them to clothing, such as belts. Currently, the commonly used sewing method is heat pressing, which involves aligning the two ends of the strip of webbing and placing it on a heat press to fix the ends of the webbing. However, the temperature at the joint of the webbing is high after heat pressing, while the adhesive used to fix the webbing cools relatively slowly. If external force is applied to the joint of the webbing at this time, the molten adhesive layer is prone to deformation, resulting in a decrease in the quality of heat pressing or even scrapping the garment. This is especially true for non-fully automated production lines, where the process is usually completed once the webbing is looped, and the webbing is collected and transported to the next process after reaching a certain quantity. In this case, the webbing is very likely to squeeze against each other, causing deformation at the joint. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a hot-pressed braided tape sewing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0025] Reference Figure 1-6 A heat-pressing braided tape sewing machine includes a machine base 1. The upper side of the machine base 1 is equipped with a first feeding mechanism 2 for conveying adhesive tape, several arranged heat-pressing devices 3, and a second feeding mechanism 8 for picking up the adhesive tape. The first feeding mechanism 2 is equipped with a cutter 7 for cutting the adhesive tape. The heat-pressing devices 3 are equipped with an adhesive cold-pressing mechanism. The front side of the machine base 1 is equipped with a third feeding mechanism 4 for conveying webbing and a conveying clamping mechanism 5 for transporting looped webbing to the heat-pressing devices 3 for heat-pressing. The front end of the third feeding mechanism 4 is equipped with a looping mechanism 6 for looping the webbing. After looping, the webbing is conveyed to the heat-pressing devices 3 via the conveying clamping mechanism 5. The second feeding mechanism 8 picks up the adhesive tape and places it at the connection point of the webbing. After heat-pressing by the heat-pressing devices 3, the adhesive is rapidly cooled and solidified by the adhesive cold-pressing mechanism. This prevents deformation caused by external force while the adhesive is in a molten state, effectively improving production quality.

[0026] The conveying clamping mechanism 5 and the coiling mechanism 6 can adopt a high-efficiency coiling mechanism for webbing disclosed in CN222455621U and a feeding mechanism for webbing coiling and sewing disclosed in CN222455466U.

[0027] The first feeding mechanism 2 includes a first mounting base 9. From back to front, the first mounting base 9 is sequentially equipped with an adhesive tape release paper separator 10, an adhesive tape traction roller assembly, the cutter 7, and an adhesive tape receiving portion 12. The adhesive tape release paper separator 10 is provided with a separation hole 13. The adhesive tape receiving portion 12 is provided with a placement groove 14 for placing the adhesive tape. The separation hole 13 is located at the rear end of the adhesive tape release paper separator 10. The raw material roll 34 of the adhesive tape is mounted on the first... When using the feeding mechanism 2, manually tear off the release paper at the front end of the adhesive tape (the adhesive tape includes a fabric strip, an adhesive layer, and a release paper. At room temperature, the adhesive layer is not sticky. After being molten through high-temperature hot pressing, it will be pressed into the webbing. After cooling and solidification, the webbing can be fixed and connected. The adhesive tape is a commercially available product). Insert the adhesive tape into the separation hole 13. The release paper is located outside the separation hole 13. When the adhesive tape is fed forward, the release paper and the adhesive tape can be separated.

[0028] The front end of the adhesive tape release paper separator 10 is provided with a guide hole 15. After the adhesive tape passes through the guide hole 15, it is pulled by the adhesive tape pull roller, which ensures the position and angle of the adhesive tape pull roller. The structure of the guide hole 15 is the same as that of the separation hole 13. They are symmetrically arranged at the front and rear ends of the adhesive tape release paper separator 10 and can be used interchangeably to further improve convenience.

[0029] The adhesive tape pulling roller assembly includes a replenishing roller 11 and a feeding roller 16. An adhesive tape detection device is installed on the first mounting base 9 between the replenishing roller 11 and the feeding roller 16. During normal use, the adhesive tape is in a concave state between the replenishing roller 11 and the feeding roller 16. When the feeding roller 16 conveys the adhesive tape to the adhesive tape waiting section 12 (the adhesive tape will be directly inserted into the placement groove 14), the placement groove 14 has a chamfered structure at one end near the feeding roller 16 for guidance, facilitating the adhesive tape... (Adhesive tape insertion) The adhesive tape between the replenishing roller 11 and the feeding roller 16 rises upwards due to its reduced length. When the adhesive tape detection device detects the adhesive tape (a laser sensor can be used; when the adhesive tape blocks the laser, the receiver of the laser sensor does not receive the laser signal, and it will control the replenishing roller 11 to rotate), the replenishing roller 11 replenishes the adhesive tape, increasing the length of the adhesive tape between the replenishing roller 11 and the feeding roller 16, and then it recoils downwards again, thus completing the replenishment operation.

[0030] The second feeding mechanism 8 includes a first slide rail 25 along the arrangement direction of the hot pressing devices 3. A second mounting base 26 is slidably mounted on the first slide rail 25. A negative pressure suction cup 27 that can slide up and down is mounted on the second mounting base 26. A mounting bracket 33 is mounted on the machine base 1. The first slide rail 25 is mounted on the mounting bracket 33. A sliding seat 28 that can slide back and forth is mounted on the second mounting base 26. The negative pressure suction cup 27 can slide up and down at the lower end of the sliding seat 28. The negative pressure suction cup 27 conveys the adhesive tape to each hot pressing device 3 for hot pressing by sliding forward, backward, up, and down.

[0031] The hot pressing device 3 includes a first mounting base 17, on which a first heat insulation block 18 is fixedly mounted. A second heat insulation block 19 that can be pressed down is mounted above the first heat insulation block 18. A hot pressing block 20 is mounted on the bottom surface of the second heat insulation block 19. The hot pressing block 20 is located between the first heat insulation block 18 and the second heat insulation block 19, avoiding direct contact with other components that could lead to heat loss or damage to other components, thereby reducing service life. The adhesive cold pressing mechanism includes a first heat dissipation block 21 mounted on the first mounting base 17 and a second heat dissipation block 22 that can be pressed down. The second heat dissipation block 22 is located above the first heat dissipation block 21. The first mounting base 17 is equipped with a clamp 23 for clamping the webbing from the first heat insulation block 18 to the first heat dissipation block 21.

[0032] The clamp 23 has push blocks 24 installed on both sides for pushing the webbing out of the hot pressing device 3. The webbing collecting device 29 includes a rotating motor 30, and a collecting rod 31 is installed on the rotating shaft of the rotating motor 30. A limiting ring 32 is installed on the collecting rod 31. When the webbing in one of the hot pressing devices 3 has cooled down, the webbing collecting device 29 moves to the corresponding position so that the front end of the collecting rod 31 is in front of the hot pressing device 3 and is in an oblique upward state. At this time, the push block 24 pushes out the webbing, and the webbing is directly put into the collecting rod 31. Due to the presence of the limiting ring 32, when the webbing abuts against the limiting ring 32, the movement stops. The webbing collecting device 29 moves to the collecting box and controls the rotating motor 30 to rotate so that the collecting rod 31 is in an oblique downward state. The webbing automatically slides into the collecting box, thus completing the collection operation.

[0033] The operation process of this product:

[0034] First, the first feeding mechanism 2 transports the adhesive tape to the adhesive tape waiting section 12, where it is cut by the cutter 7. The third feeding mechanism 4 then conveys the webbing to the front end, and production begins. The third feeding mechanism 4 continues to transport the webbing forward, where the looping mechanism 6 loops the webbing. The conveyor clamping mechanism 5 then transports the webbing to the first hot press device 3. The second feeding mechanism 8 transports the adhesive tape from the adhesive tape waiting section 12 to the bonding area of ​​the webbing on the hot press device 3. The hot press block 20 presses down, heating the adhesive tape to melt the adhesive layer. While waiting for the adhesive layer to completely melt and bond, the third feeding mechanism 4, the looping mechanism 6, and the conveyor clamping mechanism 5... The clamping mechanism 5 is restarted, transporting the webbing to each hot pressing device 3. The second feeding mechanism 8 picks up the adhesive tape, causing each hot pressing device 3 to start working sequentially. Once the adhesive layer has completely melted and the ends of the webbing are bonded, the clamp 23 moves the webbing onto the first heat sink 21. The second heat sink 22 presses down to press the connection of the webbing until the adhesive layer has cured (the cold pressing time needs to be adjusted depending on the different adhesive layer composition and the material of the heat sink). Then, the pusher 24 pushes it out (before the pusher 24 is activated, the webbing collection device 29 needs to be moved to the corresponding hot pressing device), thus completing one hot pressing connection.

[0035] In this embodiment, there are six hot pressing devices 3, three of which are installed on the left side of the machine base 1 and the other three are installed on the right side of the machine base 1. The first feeding mechanism 2 is installed in the middle of the machine base 1. There are two webbing collection devices 29, which are installed on the left and right sides of the machine base 1 respectively. Each webbing collection device 29 is responsible for collecting the webbing processed by the hot pressing device 3 on the same side.

[0036] In this application, linearly movable components (such as clamp 23) can be implemented using slide rails and sliders to increase stability. The driving device can be a linear motor, cylinder, or rotary motor in combination with gears, racks, transmission belts, etc. Rotary movable components (such as collecting rod 31) can be implemented using rotary motors, etc.
