Description

Technical Field

[0001] The utility model relates to the field of clothing production, in particular to a hot-melt hole-opening device for clothing production. Background Art

[0002] The positions of the collar holes under the collar flowers of clothing vary according to different types. Therefore, during the production process, the collar parts need to be made with corresponding and qualified collar holes. Direct manual production often results in the collar hole positions not being standardized and the hole sizes not being up to standard.

[0003] Prior art CN202122576772.8 discloses a collar drilling machine, comprising a machine platform, a support base is provided on the machine platform, a drilling assembly is slidably provided on the support base, and a driving assembly for driving the drilling assembly to slide is provided at the bottom of the machine platform. Although the utility model can open a collar installation hole on the clothes to be opened by a drilling needle, the following problems still exist:

[0004] 1. After the existing collar drilling machine completes the drilling, the material formed by the melted fabric at the opening will be sticky, which can easily cause the fabric to be lifted up when the hot melt head is lifted, causing the hot melt hole to become larger and affecting the opening quality.

[0005] 2. When the existing collar drilling machine is drilling, the material produced during hot melting will be distributed on the collar outside the hole along the hole axis under the downward pressure of the drill needle, which requires staff to grind and remove it later, affecting work efficiency.

[0006] 3. After the collar holes generated by the existing collar drilling machine are used many times, the fabric around the holes is easy to fall apart, which affects the use. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a hot melt hole opening device for clothing production, which uses a cloth pressing assembly to press the cloth, which can not only prevent the collar from being displaced when the hot melt head moves, thereby improving the accuracy and efficiency of the hole opening, but also prevent the hot melt needle from being unable to contact the cloth when it is offset, thereby ensuring product quality.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is a hot-melt hole-opening device for garment production, comprising: a workbench, a lifting device, a hot-melt assembly and a cloth-pressing assembly; the hot-melt assembly and the cloth-pressing assembly are arranged on the workbench through the lifting device and can be moved up and down by the lifting device;

[0010] The cloth pressing assembly is arranged below the hot melt assembly and can be pressed toward the workbench through a lifting device. The hot melt assembly includes a telescopic cylinder, an electric heating device and a hot melt needle. The telescopic cylinder is vertically arranged on the lifting device, and its driving end is arranged toward the workbench. The electric heating device is arranged on the driving end of the telescopic cylinder. A hot melt needle is vertically arranged at the lower end of the electric heating device. Hot melt through holes are arranged on the cloth pressing assembly and the workbench for the hot melt needle to pass through, and the diameter of the hot melt through hole is not less than the diameter of the hot melt needle.

[0011] It should be noted that the hot melt through hole refers to the through hole of the cloth pressing assembly and the through hole of the workbench that the hot melt needle needs to pass through during the hole opening process. The present solution can press the cloth tightly on the workbench or gasket by adding the cloth pressing assembly. When performing hot melt hole opening, the telescopic cylinder pushes the electric heating device and the hot melt needle downward, so that the hot melt needle passes through the cloth pressing assembly and the hot melt through hole on the workbench. The electric heating device heats the cloth around the hot melt needle to melt and form a hole in the cloth. During this process, even if the cloth is subjected to a certain pressure, it will not move under the pressure of the cloth pressing assembly, thereby ensuring the accuracy of the hole opening. After the hole opening is completed, the friction or adhesion force generated between the hot melt needle and the cloth when it rises can effectively prevent the cloth from moving under the action of the cloth pressing assembly, thereby ensuring the quality of the hole opening.

[0012] Preferably, the cloth pressing assembly comprises a pressing plate and a connecting piece, the pressing plate is fixedly arranged on the lifting device through the connecting piece, and the hot melt through holes are correspondingly arranged on the pressing plate.

[0013] It should be noted that the cloth pressing assembly consists of a pressing plate and a connecting part. The hot melt through hole on the pressing plate corresponds to the hot melt needle, which can ensure that the hot melt needle can accurately penetrate the cloth. When the hot melt needle is offset, it cannot pass through the hot melt hole on the pressing plate and damage the cloth.

[0014] Preferably, the lower surface of the pressing plate of the cloth pressing assembly is provided with anti-slip textures.

[0015] It should be noted that the anti-slip texture on the lower surface of the pressing plate increases the friction between the pressing plate and the fabric, which helps to fix the fabric more firmly during the hot melt hole opening process and prevent the fabric from sliding between the pressing plate and the workbench. Especially when the hot melt head applies downward pressure, the anti-slip texture can effectively resist the lateral force transmitted by the hot melt needle, avoid fabric displacement, and ensure the accuracy of the hole opening position.

[0016] Preferably, a pad is correspondingly provided on the workbench, the pad can abut against the downward pressing plate, and a hot melt through hole is provided on the pad corresponding to the hot melt needle.

[0017] It should be noted that the setting of the pad provides additional support and protection, avoiding the damage that may be caused by the hot melt needle directly contacting the workbench surface. At the same time, the hot melt holes on the pad cooperate with the hot melt holes on the pressure plate to ensure that the hot melt needle can smoothly penetrate the fabric and achieve accurate hole opening. The use of the pad can also reduce the impact of the heat energy generated during the hot melt process on the workbench and extend the service life of the workbench.

[0018] Preferably, the inner diameter of the hot melt through hole is the same as the outer diameter of the hot melt needle.

[0019] It should be noted that the design of keeping the inner diameter of the hot melt hole consistent with the outer diameter of the hot melt needle can ensure that the hot melt needle can accurately align and penetrate the fabric during the process of passing through the pressure plate and the pad, while reducing the gap between the hot melt needle and the hot melt hole, so that the material generated by the hot melting of the fabric cannot overflow through the hot melt hole, and can only be squeezed between the pressure plate and the pad around the collar hole to fill and reinforce the gap in the fabric around the collar hole, thereby improving the durability of the collar hole.

[0020] Preferably, a positioning block for locating the position of punching holes in clothes is provided on the pad.

[0021] It should be noted that the setting of the positioning block allows the operator to quickly and accurately align the part of the clothing to be opened with the hot melt component, reducing the time and error of manual alignment, and improving production efficiency and consistency of hole positions; the positioning block can be designed into a shape that matches a specific clothing style or size to meet the requirements of different types of collar holes.

[0022] Preferably, the hot melt assembly further comprises a temperature controller, which is connected to the electric heating device and is capable of monitoring and controlling the operating temperature of the electric heating device.

[0023] It should be noted that the addition of the temperature controller ensures temperature stability during the hot melt process, avoiding the problem of unstable hole opening effect caused by temperature fluctuations; by setting the appropriate temperature range, the hot melt treatment can be optimized for fabrics of different materials, which not only ensures the quality of the hole opening, but also avoids the risk of damage to the fabric due to overheating.

[0024] Preferably, the lower end of the hot melt needle is conical, the upper part of the conical section is a cylindrical section, and the conical section can pass through the hot melt through hole of the workbench.

[0025] It should be noted that the tapered front end of the hot melt needle can penetrate the fabric more easily and reduce the resistance when opening the hole, while the cylindrical section is conducive to maintaining the roundness of the hole and the smoothness of the edge, avoiding the generation of sharp angles or burrs.

[0026] Preferably, the lifting device includes a lifting frame, a sliding block, a driving motor and a lifting screw. The lifting frame is arranged on a workbench. The lifting screw is vertically arranged in a sliding groove of the lifting frame and is connected to the driving motor. The driving motor is arranged at the upper end of the lifting frame. The sliding block is sleeved on the lifting frame and moves up and down along the sliding groove through the lifting screw. The hot melt assembly and the cloth pressing assembly are arranged on the sliding block.

[0027] Beneficial effects of the utility model:

[0028] The utility model provides a hot-melt hole-opening device for clothing production. Through the arrangement of a cloth pressing component, the cloth can be firmly fixed during the hot-melt hole-opening process to prevent the cloth from being displaced during the hole-opening, thereby ensuring the accuracy and consistency of the hole-opening and improving the production efficiency at the same time. The hot-melt through-hole and the hot-melt needle are closely matched to limit the material generated during the hot-melt process from overflowing outward, so that the hot-melt material is filled to reinforce the cloth gap around the collar hole, reducing the amount of material that needs to be removed by later grinding, simplifying the production process, improving the tensile strength of the collar hole, and reducing the problem of cloth line scattering around the hole after repeated use. The integration of the temperature controller ensures the stability of the working temperature of the electric heating device, making the hot-melt process more controllable, and is suitable for cloths of different materials, ensuring the hole-opening quality and the safety of the cloth.

[0049] The working principle and use method of a hot melt hole opening device for clothing production in this embodiment:

[0050] The hot-melt hole-opening device for clothing production provided in this embodiment is preheated to a temperature suitable for a specific type of fabric under the monitoring of a temperature controller 34 by an electric heating device 32, ensuring that the fabric can be effectively melted without causing damage when opening the hole; the hot-melt through-hole 5 on the cloth pressing assembly 4 and the workbench 1 not only provides a channel for the hot-melt needle 33, but also effectively limits the overflow of molten material through its precisely matched size (the inner diameter is the same as the outer diameter of the hot-melt needle 33), ensuring the cleanliness of the hole-opening process and the neatness of the hole edge, but also applies constant pressure to the clothing during the hole-opening process, ensuring that the fabric does not move during the hot-melt process, thereby ensuring that the position of the hole is accurate; the conical design of the hot-melt needle 33 facilitates penetration of the fabric, and the cylindrical section above the conical section ensures that the hole shape is regular.

[0051] When in use, first, place the collar of the clothing to be processed flatly on the pad 6 on the workbench 1, ensure that the edge of the collar is aligned with the positioning block 61 on the pad 6, so that the hole position can be quickly and accurately determined, then turn on the power, preheat the electric heating device 32 to the set temperature, the temperature controller 34 monitors and adjusts the temperature of the electric heating device 32, ensure that the temperature during the hot melting process is stable and suitable for the current fabric type; and adjust the height of the cloth pressing assembly 4 and the hot melting assembly 3 through the lifting device 2, so that the pressing plate 42 is lightly pressed on the clothing, and the anti-slip grooves 421 on the pressing plate 42 increase the friction with the clothing to ensure that the clothing does not slide during the processing, and then the operator starts the telescopic cylinder 31, the electric heating device 32 moves down accordingly, and the hot melting needle 33 passes through the hot melting through hole 5 on the pressing plate 42 and the pad 6, contacts and penetrates the clothing, at this time, the electric heating device 32 heats the hot melting needle 3 3 is melted to form a hole. Since the inner diameter of the hot-melt through hole 5 is the same as the outer diameter of the hot-melt needle 33, this limits the overflow of the molten material and ensures the cleanliness and efficiency of the hole-opening process. While the hot-melt needle 33 moves downward, the cloth-pressing assembly 4 continues to apply a certain pressure to the clothes to prevent the cloth from unnecessary displacement during the hot-melt process and ensure the accurate position and size of the hole. When the hot-melt needle 33 reaches the predetermined depth, the telescopic cylinder 31 moves in the reverse direction, and the electric heating device 32 and the hot-melt needle 33 retreat to complete the hole-opening operation of the collar hole. During this process, the cloth-pressing assembly 4 continues to work until the hot-melt needle 33 is completely withdrawn to prevent the cloth from moving with the hot-melt needle 33 and ensure the neatness of the hole edge. The above steps are repeated until all the predetermined hole positions of the clothes are opened. After all operations are completed, the hole quality is checked, the clothes are sorted, the equipment is turned off, and the processing flow is ended.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, and is not used to limit the protection scope of the utility model.
