Description

Technical Field

[0001] This invention belongs to the field of garment production technology, and in particular relates to a hot-melt wrapping method that can prevent the buckle from collapsing. Background Technology

[0002] With the continuous development of the garment industry, the requirements for automation and intelligence in garment production are increasing. When using a button sewing machine or manually to fix four-hole, two-hole, or mushroom-shaped buttons to clothing with sewing thread, it becomes very difficult to fasten the buttons if there is not enough space between the buttons and the fabric. This also stretches the buttonhole and leaves unsightly creases and wrinkles on the fabric around the buttonhole. Therefore, people sometimes intentionally leave a gap between the button and the fabric when sewing. However, this makes the buttons difficult to fasten securely, causing them to easily fall off and not stand upright on the fabric, affecting the appearance. Furthermore, four-hole buttons, fixed to the fabric by four sets of sewing thread, still stretch the buttonhole. To ensure secure and aesthetically pleasing button sewing, current technology uses a manual winding method to combine the four sets of thread into a single thick thread. The disadvantages of this manual winding method are: slow winding speed and poor consistency. To increase the winding speed, knot-tying winding machines were developed. However, existing winding machines use knots to bind the four sets of thread together with sewing thread. This method is prone to coming undone, failing to achieve the purpose of securing the buttonhole thread and preventing the button from falling off. Furthermore, the knotted method leaves two thread tails during finishing, requiring manual trimming. While it significantly improves efficiency compared to the original purely manual processing, it still cannot meet the demands of large-scale garment production and high-quality garment craftsmanship.

[0003] Chinese patent CN112048833B discloses a processing method for an intelligent fully automatic hot-melt button wrapping machine, comprising the following steps: A. Start the button wrapping machine and sequentially place buttons connected to fabric into the button feeding channel of the automatic button placement device; B. When the button at the bottom of the button feeding channel enters the waiting position and touches the touch switch, the button feeding device moves the button at the waiting position to the processing position for processing, and after processing, proceed to the next step; C. The buttons in the button feeding channel continue to fall, and when the button at the bottom of the button feeding channel enters the waiting position and touches the touch switch, the button feeding device moves the processed button at the processing position to the button dropping position, and at the same time moves the button at the waiting position to the processing position for processing; D. Repeat step C until there are no buttons in the button feeding channel, completing the processing of all buttons. The entire processing process of this invention does not require manual assistance, saving manpower and improving processing efficiency;

[0004] The aforementioned patent enables automatic button wrapping. However, the button needs to move to the processing position and stop after wrapping. After wrapping, the button stops to wrap the wire again before moving to the next position, which wastes time and reduces work efficiency. Summary of the Invention

[0055] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0056] Example 1

[0057] This invention provides a hot-melt wrapping method to prevent buckle feet from collapsing, such as... Figures 1-4 As shown, it includes the following steps:

[0058] a. Start the button wrapping machine, which includes:

[0059] frame;

[0060] The loading station 13 and unloading station 12 are located on the machine frame;

[0061] The transfer unit, located on the frame, is used to transfer buttons from the loading station 13 to the unloading station 12;

[0062] The winding unit, located on the frame, winds hot melt wire at the connection between the button and the fabric during the movement of the button from the loading station 13 to the unloading station 12.

[0063] The hot-melt unit, located on the frame, is used to secure the wound hot-melt thread at the junction of the button and the fabric;

[0064] Place the button with the attached fabric into the feeding station 13;

[0065] b. The material transfer unit includes a material transfer plate 4 and a power component for driving the material transfer plate 4 to rotate. The material transfer plate 4 has multiple openings circumferentially spaced in the button slots 26. The buttons enter the button slots 26 from the loading station 13 and are driven to rotate by the power component. The material transfer plate 4 drives the buttons to move. Specifically, the outer side of the material transfer plate 4 is provided with an arc-shaped outer baffle 3 to prevent the buttons from detaching from the material transfer plate 4 during the material transfer process.

[0066] c. The winding unit includes a mounting ring 5 and a winding mechanism 7 opposite to the button slot 26. The number of winding mechanisms 7 is equal to the number of button slots 26 and they correspond one-to-one. Multiple sets of winding mechanisms 7 are fixedly fixed to the mounting ring 5 at circumferential intervals. The mounting ring 5 is opposite to the material transfer plate 4 and is fixedly connected to the material transfer plate 4 through a connecting rod 8. During the movement of the button, the winding mechanism 7 simultaneously winds hot melt wire around the connection between the button and the fabric.

[0067] d. After the hot melt thread is wrapped around the button, the hot melt unit heats the hot melt thread at the connection between the button and the fabric to melt the head and tail of the hot melt thread. Then, the material turntable 4 drives the button to the unloading station 12 to complete the processing.

[0068] Understandably, by setting up multiple winding mechanisms 7, and having the winding mechanisms 7 move synchronously with the buttons, the winding mechanisms 7 simultaneously wrap the hot melt wire around the connection between the buttons and the fabric during the button's movement. This eliminates the need for the buttons to stop at the winding processing station to wind the wire before moving to the hot melt station, saving time and improving work efficiency.

[0069] The winding mechanism 7 includes:

[0070] The telescopic rod 15 is rotatably mounted on the mounting ring 5. Preferably, the telescopic rod 15 can be an electric push rod, which can be rotatably mounted via a bearing. In the prior art, for rotating electrical components, brush power supply can be used, which will not be elaborated here.

[0071] A support rod 16 is fixed to the telescopic end of the telescopic rod 15 and perpendicular to it. A threading rod 17 is fixed to the end of the support rod 16 away from the telescopic rod 15. It can be fixed by welding. A threading hole 21 is provided on the threading rod 17 along its radial direction. The distance between the threading rod 17 and the rotating material plate 4 can be adjusted by the telescopic rod 15.

[0072] The driven drive wheel 25 fixed on the telescopic rod 15 can be fixed with screws. The frame is fixed with fixed drive wheels 6 that cooperate with multiple driven drive wheels 25 respectively. In this embodiment, the fixed drive wheels 6 are fixedly connected to the frame through the fixed rod 14. The driven drive wheel 25 and the fixed drive wheel 6 can be meshing gears or friction-fitting rubber wheels. The fixed drive wheel 6 is coaxial with the rotating disc 4.

[0073] It needs to be explained that when the material transfer plate 4 rotates, it drives the mounting ring 5 and the telescopic rod 15 to revolve. The telescopic rod 15 drives the driven drive wheel 25 to move relative to the fixed drive wheel 6, causing the driven drive wheel 25 to rotate, thus causing the telescopic rod 15 to rotate. The telescopic rod 15 drives the threading rod 17 to revolve around the center, winding the hot melt thread around the connection between the button and the fabric.

[0074] Preferably, the fixed drive wheel 6 and the driven drive wheel 25 are pneumatic wheels, which can adjust their diameter by inflating and deflating the air, thereby adjusting the transmission ratio between the fixed drive wheel 6 and the driven drive wheel 25, and achieving the effect of adjusting the number of windings.

[0075] Specifically, at least one gripper 27 for fixing the head of the hot melt wire is installed on the transfer tray 4 and at the movement trajectory of the threading rod 17. Preferably, the gripper 27 is pneumatic, similar to the principle of a telescopic cylinder, which is existing technology. The gripper 27 is provided with an adsorption hole for adsorbing the wire head to move toward the gripper 27. The adsorption hole can be connected to a vacuum tube. Of course, an air nozzle can also be set on the mounting ring 5 at a position opposite to the gripper 27. By blowing the head of the hot melt wire toward the gripper 27, the gripper 27 clamps the wire head. Alternatively, the existing method of fixing the wire head of the winding machine can be used without too many restrictions.

[0076] Furthermore, the threading rod 17 is provided with a wire-cutting mechanism, which includes:

[0077] A cutter 19 is slidably mounted on the outer wall of the threading rod 17 and located on one side of the threading hole 21. The cutter 19 can be set in an arc shape. An anvil plate that cooperates with the cutter 19 is provided on the outer wall of the threading rod 17 and on the other side of the threading hole 21. A first spring is fixedly connected between the end of the cutter 19 away from the threading hole 21 and the outer wall of the threading rod 17. The force of the first spring on the cutter 19 is directed towards the threading hole 21.

[0078] An electromagnet 18 is fixed inside the threading rod 17, and the electromagnet 18 cooperates with the first iron block 20 fixed on the cutter 19.

[0079] During winding, electromagnet 18 is energized and attracts the first iron block 20 of the column. Before the wire melts after winding, electromagnet 18 is de-energized. Under the action of the first spring, cutter 19 moves toward wire hole 21 to cut the wire. At the same time, gripper 27 releases the wire end. Then the hot-melting unit performs the hot-melting operation. At the beginning of the hot-melting unit, an infrared receiver can be fixed on the frame, and an infrared transmitter can be installed on the turntable on one side of the slot 26. When the signal emitted by the infrared transmitter is received by the infrared receiver, it is fed back to the controller. The controller is a microcontroller. The controller controls the electromagnet 18 to be de-energized. Of course, other wire breaking schemes in existing winding machines can also be used. The tail of the hot-melting wire can also be melted directly by the heat of the hot-melting unit without the need for a wire breaking mechanism. As long as the work can be completed, there are no too many restrictions.

[0080] In practice, the spool 28 can be fitted onto the telescopic rod 15, and then a nut can be threaded onto the end of the telescopic rod 15 to prevent the spool 28 from falling off.

[0081] Furthermore, it also includes a wire clamping mechanism, which comprises:

[0082] The drive roller 24 and the squeeze roller 23 are rotatably mounted on the wire rod 17 and located on both sides of the wire hole 21. The drive roller 24, which is away from the electromagnet 18, is driven to rotate by a micro motor. The squeeze roller 23, which is close to the electromagnet 18, is rotatably mounted on the second iron block 22. The second iron block 22 is sleeved on the pin fixed on the electromagnet 18.

[0083] The second spring is installed inside the second iron block 22. One end of the second spring abuts against the end of the pin. The force exerted by the second spring on the second iron block 22 is directed toward the drive roller 24.

[0084] After the electromagnet 18 is de-energized, the cutter 19 moves toward the anvil to cut the hot melt wire. At the same time, the second spring pushes the second iron block 22 to move the extrusion roller 23 toward the drive roller 24. The extrusion roller 23 and the drive roller 24 clamp the hot melt wire to prevent it from separating from the threading rod 17. Of course, the drive roller 24 can be rotated by a micro motor. The drive roller 24 drives the head of the hot melt wire to move and extend it out of the threading rod 17. The longer length outside the threading rod 17 can be better clamped and held by the gripper 27.

[0085] In this embodiment, the hot-melt unit includes:

[0086] Two arc-shaped heating bars 9 are arranged radially at intervals along the transfer tray 4. The space between the two arc-shaped heating bars 9 is a movement channel for the connection between the button and the fabric.

[0087] Two arc-shaped heating bars 9 are respectively fixed on two elastic movable rods 10. The outer elastic movable rod 10 can be fixedly connected to the frame, and the inner elastic movable rod 10 can be fixedly connected to the fixed rod 14. The elastic movable rod 10 is composed of two rods, one rod is movably inserted into the other rod, and the other rod is provided with a third spring. The third spring is a compression spring, which can push one rod and the arc-shaped heating bar 9 fixed on it to move. In the natural state, the two arc-shaped heating bars 9 are brought closer together. In this embodiment, the fixed connection can be fixed by welding.

[0088] After the winding mechanism 7 winds the thread, the transfer tray 4 continues to rotate, driving the button into the space between the two arc-shaped heating strips 9. The two arc-shaped heating strips 9 heat the hot melt thread wound at the connection between the button and the fabric, fusing them together. After melting and bonding, the thread opening will not come loose during future use, thus preventing the button from falling off. At the same time, the appearance is neat and clean. The arc-shaped heating strips 9 can be used with a temperature controller to adjust the heating temperature and improve adaptability. Of course, heating can also be achieved using the existing hot melt clamp, but the hot melt clamp method requires the button to stop before heating can be performed. The solution in this embodiment heats the button simultaneously during its movement, further improving work efficiency.

[0089] In specific implementation, it also includes a loading and unloading unit, which includes:

[0090] The loading platform 1 is fixedly installed on the frame and located on the side of the loading station 13. The end of the loading platform 1 is attached to the outer wall of the rotating tray 4.

[0091] The feeding conveyor belt 2, which is installed on the frame and located above the feeding platform 1, is used to drive the buttons to move one by one from the feeding platform 1 to the rotating tray 4.

[0092] The unloading conveyor belt 11 is installed below the unloading station 12.

[0093] In use, the buttons are placed side by side between the loading platform 1 and the loading conveyor belt 2 at the connection points with the fabric. The friction of the buttons on the loading conveyor belt 2 during its movement drives the buttons to move one by one to the loading station 13. After the heat-melting process is completed, the buttons move to the unloading station 12 and then fall onto the unloading conveyor belt 11, completing the automatic loading and unloading and improving work efficiency.

[0094] Example 2

[0095] This embodiment is based on embodiment 1, such as Figures 5-6 As shown, it also includes a tensioning unit, which is mounted on the mounting ring 5 and located on one side of the corresponding winding mechanism 7. The tensioning unit includes:

[0096] A guide plate 36 is fixed on the mounting ring 5, and the guide plate 36 has a guide hole through which the heating wire passes;

[0097] Rotate the mounting plate 31 mounted on the mounting ring 5. A torsion spring 30 connects the mounting plate 31 and the mounting ring 5. Figure 5 As shown, the force exerted by the torsion spring 30 on the mounting rod is clockwise;

[0098] Rotate the tensioning wheels 29 installed at both ends of the mounting plate 31, and the hot melt wire passes between the two tensioning wheels 29;

[0099] Furthermore, a detection unit is provided on a tensioning wheel 29 for detecting whether a wire breakage has occurred. The detection unit includes:

[0100] The movable block 33 has a mounting groove on the side wall of the tensioning wheel 29 for mounting the movable block 33, and the movable block 33 is slidably connected to the groove wall of the mounting groove.

[0101] A pressure sensor 34 is fixed in the mounting slot and is electrically connected to the alarm light via a wire.

[0102] A fourth spring 35 is provided between the pressure sensor 34 and the movable block 33. The force exerted by the fourth spring 35 on the movable block 33 is directed toward the outside of the tension wheel 29.

[0103] When the wire breaks, the hot melt wire loses its force on the movable block 33, causing the movable block 33 to move outward. The value of the pressure sensor 34 changes, and when it exceeds the set value, it is fed back to the controller of the alarm light, causing the alarm light to light up and triggering an alarm to remind the staff to perform maintenance.

[0104] In summary, this invention provides a hot-melt wrapping method that can prevent the buckle from collapsing, and its working principle is as follows:

[0105] The buttons are placed side-by-side between the loading platform 1 and the loading conveyor belt 2, with the connection points between the buttons and the fabric. The friction between the buttons and the conveyor belt 2 during its movement causes them to move one by one to the loading station 13. From the loading station 13, the buttons enter the button slot 26. A power unit drives the rotating disc 4 to rotate, which in turn moves the buttons. As the disc 4 rotates, it causes the mounting ring 5 and the telescopic rod 15 to revolve. The telescopic rod 15 then drives the driven drive wheel 25 to rotate relative to the fixed drive wheel 6, causing the driven drive wheel 25 to rotate on its own axis. The telescopic rod 15 rotates, which in turn drives the threading rod 17 to revolve around the central axis, winding the hot melt wire around the connection between the button and the fabric. After the winding mechanism 7 winds the wire, the material transfer plate 4 continues to rotate, driving the button between the two arc-shaped heating strips 9. The two arc-shaped heating strips 9 heat the hot melt wire wound around the connection between the button and the fabric, fusing it into one piece. After the hot melt process is completed, the button moves to the unloading station 12 and then falls onto the unloading conveyor belt 11, completing the automatic loading and unloading and improving work efficiency.
