Description

Technical Field

[0001] This utility model relates to the field of fabric overlocking technology, specifically a hot melt overlocking device for fabric. Background Technology

[0002] The overlock structure formed by hot melt adhesive lines can enhance the strength of the fabric edges and reduce fraying and unraveling. Hot melt overlocking requires a hot melt device. Existing hot melt devices have a heating box and a heating module set in the heating box. The heating module heats the hot melt adhesive lines on the fabric. However, because the opening of the heating box is relatively narrow and the fabric itself is relatively soft, auxiliary tools are needed when passing the fabric through the heating box, which is cumbersome and difficult to meet the usage requirements. Utility Model Content

[0003] The purpose of this invention is to provide a hot-melt overlock device for fabrics, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the hot-melt overlock device for fabric includes: The material feeding section is used to store the material roller, on which fabric is wound. Hot melt adhesive threads are sewn on both sides of the fabric. When the fabric is subjected to external traction, the material roller can rotate on the material feeding section. The heating section is capable of heating the hot melt adhesive lines on both sides of the fabric; The driving unit is disposed on the heating unit and is used to pull the fabric to move, so that the fabric on the material roller is unwound, and at the same time the unwound fabric passes through the heating unit; A cooling section is provided at one end of the heating section, and the cooling section is used to cool the hot melt adhesive lines on both sides of the heated fabric.

[0005] Preferably, the feeding section includes a base plate, and support plates are respectively provided on both sides of the upper surface of the base plate. An arc-shaped groove is provided on the support plate, and bearings are respectively provided at both ends of the material roller. Both bearings can be placed in the arc-shaped groove.

[0006] Preferably, the heating part includes a heating box, with two heating modules respectively arranged on the left and right sides inside the heating box, the two heating modules being arranged vertically, a fixing plate being provided inside the heating box, and a support roller being provided at one end of the heating box, the width of the support roller being smaller than the width of the fabric roll.

[0007] Preferably, the drive unit includes two mounting slots on the heating box, each mounting slot having a rotating module inside. Each rotating module includes two rollers rotatably connected to the mounting slot, and also includes an annular toothed belt with a patterned outer surface. The toothed belt connects the two rollers, and the rollers between the two sets of rotating modules are connected by a synchronous shaft. A mounting plate is provided on one side of the heating box, and a motor is provided on the mounting plate. The output end of the motor is connected to one end of the rotating shaft.

[0008] Preferably, the cooling section includes two side plates disposed at one end of the heating box, the two side plates being located on both sides of the support roller, and cooling fans are installed on the side plates.

[0009] The beneficial effects of this utility model are: When using this overlocking device, simply place the front end of the fabric under the two toothed belts. Then, through the action of the motor and synchronous shaft, the toothed belts will rotate. The friction between the toothed belts and the fabric will move the fabric and allow it to pass through the heating box. This improves the convenience of the fabric passing through the heating box. In addition, the mounting slot can prevent the heat generated by the heating module from diffusing to the center of the heating box, reducing the rate of heat loss from the heating module.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, a hot-melt overlock device for fabric includes: The feeding section is used to store the material roller 1. The material roller 1 is wound with fabric 2. Hot melt adhesive threads 3 are sewn on both sides of the fabric 2. When the fabric 2 is subjected to external traction, the material roller 1 can rotate on the feeding section. The heating section is capable of heating the hot melt adhesive lines 3 on both sides of the fabric 2; The drive unit is mounted on the heating unit and is used to pull the fabric 2 to move, so that the fabric 2 on the material roller 1 is unwound, and at the same time the unwound fabric 2 passes through the heating unit. The cooling section is located at one end of the heating section and is used to cool the hot melt adhesive lines 3 on both sides of the heated fabric 2.

[0018] The hot melt adhesive yarn 3 is prepared by coating the outer periphery of the core yarn 1 with a vinyl acetate copolymer resin layer 2, which preferably has a vinyl acetate content of 5-50 wt%, and the fineness preferably is 400-6000 denier. The amounts of the core yarn and the ethylene-vinyl acetate copolymer resin are 10-50 wt% and 90-50 wt%, respectively.

[0019] The fabric 2 used in this application is a plain weave fabric made of fiberglass, which has high temperature resistance. A schematic diagram of the plain weave fabric and the hot melt adhesive line 3 is shown below. Figure 5 As shown.

[0020] Furthermore, the feeding section includes a base plate 5, and support plates 6 are respectively provided on both sides of the upper surface of the base plate 5. Arc-shaped grooves are provided on the support plates 6, and bearings 4 are respectively provided at both ends of the material roller 1. Both bearings 4 can be placed in the arc-shaped grooves.

[0021] The bearing 4 is fixedly connected to the material roller 1. When the material roller 1 is placed in the arc groove on the two support plates 6, the outer surface of the bearing 4 is in contact with the inner surface of the arc groove. Through the weight of the material roller 1 itself and the weight of the fabric 2 on the material roller 1, the outer ring of the bearing 4 can generate sufficient friction with the support plate 6. When the fabric 2 on the material roller 1 is subjected to external traction, the material roller 1 can rotate, but the bearing 4 basically remains stationary.

[0022] Furthermore, the heating section includes a heating box 18, with two heating modules 7 respectively arranged on the left and right sides inside the heating box 18. The two heating modules 7 are arranged vertically. A fixing plate 8 is provided inside the heating box 18, and a support roller 9 is provided at one end of the heating box 18. The width of the support roller 9 is smaller than the width of the fabric roll.

[0023] Heating module 7 is a resistance wire heater and is equipped with a temperature control module to control the heating temperature. The distance between the upper and lower heating modules 7 is about 6cm. At the same time, the fabric 2 needs to be laid flat on the fixing plate 8. When the fabric 2 moves on the fixing plate 8, the fabric 2 will pass through the middle of the two heating modules 7. The upper and lower heating modules 7 can heat the hot melt adhesive lines 3 on the upper and lower sides of the fabric 2 at the same time. When the hot melt adhesive lines 3 are heated by the heating modules 7, the moving speed of the fabric 2 in the heating box 18 needs to be controlled by the drive unit so that the hot melt adhesive on the surface of the hot melt adhesive lines 3 can melt, but the hot melt adhesive will not detach from the core wire. Since the core wire inside the hot melt adhesive lines 3 does not directly contact the electric heating module 7, when the heat generated by the heating module 7 melts the hot melt adhesive on the surface of the hot melt adhesive lines 3, it will not burn out the core wire inside the hot melt adhesive lines 3.

[0024] Hot melt adhesive thread 3 is pre-sewn onto both sides of fabric 2 using sewing equipment. When the hot melt adhesive on the surface of hot melt adhesive thread 3 melts, the melted hot melt adhesive can fuse with fabric 2. After the hot melt adhesive cools and solidifies, hot melt adhesive thread 3 and fabric 2 become one, thereby achieving the edge-locking effect of fabric 2.

[0025] Furthermore, the drive unit includes two mounting slots 10 disposed on the heating chamber 18. Each mounting slot 10 is equipped with a rotating module. The rotating module includes two rollers 11 rotatably connected to the mounting slots 10. It also includes an annular toothed belt 12 with a patterned outer surface. The toothed belt 12 is used to connect the two rollers 11. The rollers 11 between the two sets of rotating modules are connected by a synchronous shaft 13. A mounting plate 14 is disposed on one side of the heating chamber 18. A motor 15 is disposed on the mounting plate 14. The output end of the motor 15 is connected to one end of the rotating shaft.

[0026] The surface of the roller 11 is provided with teeth, and the inner side of the toothed belt 12 is provided with teeth. The teeth on the roller 11 can mesh with the teeth on the toothed belt 12. When the motor 15 drives the synchronous shaft 13 to rotate, it can simultaneously drive the roller 11 in the two rotating modules to rotate, and then drive the two toothed belts 12 to move synchronously. Since the surface of the toothed belt 12 has a pattern, when the toothed belt 12 moves, sufficient friction is generated between the pattern on the surface of the toothed belt 12 and the fabric 2, so that the fabric 2 can move along with the movement of the toothed belt 12. That is, through the movement of the toothed belt 12, the fabric 2 on the material roller 1 can be continuously released, and at the same time, the fabric 2 passes through the heating box 18.

[0027] The motor 15 is controlled by the controller, which can control the speed of the motor 15. It is necessary to keep the toothed belt 12 at an appropriate moving speed to avoid serious slippage between the toothed belt 12 and the fabric 2. In addition, the distance between the toothed belt 12 and the fixing plate 8 should be less than the thickness of the fabric 2 to increase the friction between the toothed belt 12 and the fabric 2.

[0028] Furthermore, the cooling section includes two side plates 16 located at one end of the heating box 18. The two side plates 16 are respectively located on both sides of the support roller 9. A cooling fan 17 is installed on the side plate 16. When the hot melt adhesive line 3 on the fabric 2 has been heated and melted and fused with the fabric 2, the fabric 2 will be continuously moved out of the heating box 18. During the removal process, the cooling fan 17 will blow air towards the hot melt adhesive line 3 to accelerate the curing efficiency of the hot melt adhesive line 3. After being cooled by the cooling fan 17, the curing time of the hot melt adhesive line 3 is about 7 seconds. After the hot melt adhesive has cured, the fabric 2 can be wound up by a winding device. The winding speed of the winding device is matched with the moving speed of the fabric 2.

[0029] The support roller 9 can support the fabric 2, and at the same time, the support roller 9 can also avoid contact with the hot melt adhesive lines 3 on both sides of the fabric 2, and prevent the hot melt adhesive on the hot melt adhesive lines 3 from adhering to the support roller 9 before it is fully cured.
