Description

Technical Field

[0001] This utility model relates to the field of garment hot pressing forming technology, specifically to a hot pressing device for stretching and pressing elastic bands at the waist and cuffs. Background Technology

[0002] In the production of outdoor and functional clothing such as windproof jackets and sun-protective clothing, elastic bands are commonly bonded to the fabric using a hot-pressing process to achieve windproof and snug fit in areas like the waistband and cuffs. These elastic bands possess significant elastic deformation characteristics, which are central to their functionality, but also present a significant challenge to the processing. Currently, the industry largely relies on manual operation for processing elastic bands: operators must manually stretch the elastic band to a predetermined length, precisely position its ends or specific points at the hot-pressing location, maintain stability while stretched, and finally use hot-pressing equipment (such as high-frequency heat sealing machines or ultrasonic welding machines) to press and fix it in place.

[0003] Traditional manual operation methods have several inherent drawbacks: 1) Difficulty in controlling precision: The length of the elastic band pulled, the tension applied, and the positioning accuracy are highly dependent on the operator's experience, feel, and concentration. The elasticity of the elastic band makes it prone to shrinkage or overstretching during the stretching process, resulting in deviations in the actual effective length of the elastic band after pressing (affecting tightness) and the pressing position, leading to large product dimensional tolerances. 2) Poor consistency: It is difficult to completely reproduce the operations between different operators, or by the same operator at different times or on different batches of products. This results in significant differences in the tightness and position of the elastic band in different parts (such as the left and right cuffs) of the same garment or in different batches of garments, seriously affecting the standardization of the product and the overall appearance quality. 3) Low production efficiency: The steps of manual pulling, positioning, holding, and pressing are cumbersome and require a high degree of concentration, limiting the overall operation speed and becoming a bottleneck restricting the production cycle.

[0004] 4) Significant safety hazards: Operators' hands frequently need to operate at close range in the high-temperature hot press head area to place, adjust, and fix the elastic bands. There is an extremely high risk of burns, especially under prolonged, high-intensity working conditions; the safety hazard cannot be ignored. 5) Unstable yield rate: The aforementioned precision and consistency issues directly lead to defective products or rework due to problems such as inaccurate elastic band length, uneven pressing, misalignment, and delamination, increasing production costs.

[0005] Therefore, the existing technology that relies on manual processing of elastic bands at the waist and cuffs has become a key bottleneck restricting the improvement of quality stability, production efficiency, and operational safety in such functional garments. There is an urgent need to develop a specialized device that integrates automatic, precise stretching and positioning of elastic bands with heat pressing functions to completely overcome the limitations of manual operation. Utility Model Content

[0006] The purpose of this utility model is to provide a hot pressing device for stretching and pressing elastic bands in waistbands and cuffs, aiming to overcome the defects of the existing technology and solve the problems of precision and consistency. These problems directly lead to defective products or rework caused by inaccurate elastic band length, uneven pressing, skewing, and delamination, which increases production costs.

[0007] To address this, the present invention proposes a hot pressing device for stretching and pressing elastic bands in waistbands and cuffs, comprising a hot pressing board; a hot pressing actuator; a horizontal guide assembly; a horizontal drive assembly; and a pair of vertical clamping mechanisms. The pair of vertical clamping mechanisms are mounted on the horizontal guide assembly and are used to clamp the two ends of the elastic band. The horizontal drive assembly drives the pair of vertical clamping mechanisms to move in opposite directions along the horizontal guide assembly, stretching the elastic band to a set length. The hot pressing actuator presses the stretched elastic band with the fabric to form a semi-finished waistband or cuff.

[0008] As a preferred technical solution of this application, the vertical clamping mechanism includes: a lower clamping member, an upper clamping member, and a lifting drive assembly; the lifting drive assembly is fixedly connected to the lower clamping member, and its movable end is connected to the upper clamping member, driving the upper clamping member to lift and lower to clamp / release the elastic band.

[0009] As a preferred technical solution of this application, the lifting drive assembly and the horizontal drive assembly are telescopic cylinders, electric cylinders, hydraulic cylinders or electric push rods.

[0010] As a preferred technical solution of this application, the left vertical clamping mechanism is fixed to one end of the horizontal guide assembly through a vertical connecting plate and a connecting member 1; the right vertical clamping mechanism is connected to the sliding member of the horizontal guide assembly through a vertical connecting plate and a connecting member 2; the two ends of the horizontal drive assembly are respectively fixedly connected to the connecting member 1 and the connecting member 2.

[0011] As a preferred technical solution of this application, both the first connecting member and the second connecting member are L-shaped connecting plates.

[0012] As a preferred technical solution of this application, the horizontal guide component is a lead screw and nut assembly or a guide rail and slider module.

[0013] As a preferred technical solution of this application, the horizontal guide component includes a horizontal guide rail and a slider, forming a guide rail slider module.

[0014] As a preferred technical solution of this application, the bottom of the horizontal guide rail is fixed to the transverse support structure; the two ends of the transverse support structure are installed on the horizontal worktable through connecting components.

[0015] As a preferred technical solution of this application, the hot pressing actuator includes: a rotatable multi-prism roller, heating elements and cooling elements disposed on different prism surfaces, and a rotation drive mechanism for driving the multi-prism roller to rotate; the heating elements are alternately pressed against the elastic band and the fabric by rotation, and then the cooling elements are shaped and reinforced.

[0016] The hot pressing device provided by this utility model for stretching and pressing elastic bands at the waist and cuffs uses a horizontal drive component to link a pair of vertical clamping mechanisms to move along the horizontal guide component, thereby stretching the elastic band and ensuring the accuracy of the stretching length to meet the requirements of high-end garment manufacturing processes. The entire process is automatically executed by pneumatic / electric components, which improves efficiency compared to manual operation and achieves a yield rate of over 99%, significantly reducing the rework rate.

[0017] By integrating automatic elastic band pulling, precise positioning, and hot pressing functions, it effectively solves the core problems of low precision, poor consistency, low efficiency, and poor safety caused by manual operation. It achieves high-quality, high-efficiency, and high-safety hot pressing processing of waistband and cuff elastic bands, which has significant practical value and promotion prospects.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-4 As shown, the hot pressing device for stretching and pressing elastic bands for waistbands and cuffs according to this utility model includes: a hot pressing board 2, a hot pressing actuator 15, a horizontal guide assembly, a horizontal drive assembly 6, and a pair of vertical clamping mechanisms; the pair of vertical clamping mechanisms are installed on the horizontal guide assembly, and after clamping the two ends of the elastic band 11, the pair of vertical clamping mechanisms are driven by the horizontal drive assembly 6 to stretch to a set length. The hot pressing actuator 15 is responsible for performing the final hot pressing and cooling curing process, pressing the stretched elastic band 11 together with the fabric 12 to form a cuff semi-finished product or a waistband semi-finished product.

[0027] Specifically, the vertical clamping mechanism includes: a lower clamping member 8, an upper clamping member 9, and a lifting drive assembly 10; the lifting drive assembly 10 is a telescopic cylinder, the lifting drive assembly 10 is fixedly connected to the lower clamping member 8, and the movable end of the lifting drive assembly 10 is connected to the upper clamping member 9; the elastic band 11 located between the lower clamping member 8 and the upper clamping member 9 is clamped by the lifting and lowering of the lifting drive assembly 10.

[0028] The left vertical clamping mechanism is connected to one end of the horizontal guide assembly via the vertical connecting plate 7 and connecting member 13. The right vertical clamping mechanism is connected to the sliding member 5 at the other end of the horizontal guide assembly via the vertical connecting plate and connecting member 2 16. At the same time, connecting member 13 and connecting member 2 16 are fixedly connected to both ends of the horizontal drive assembly 6. By extending and shortening the horizontal drive assembly, the horizontal distance between the pair of vertical clamping mechanisms can be adjusted, thereby stretching the elastic band to a predetermined length.

[0029] The horizontal drive component 6 is a telescopic cylinder; the horizontal guide component includes a horizontal guide rail 4 and a slider 5. Specifically, the horizontal guide component is a guide rail slider module, which has a guide rail and a slider. The bottom of the horizontal guide rail 4 is fixedly installed on the transverse support structure 3, and both ends of the transverse support structure 3 are fixedly installed on the upper end of the horizontal worktable 1 of the hot press device through connecting component three 14. The connecting component one 13, connecting component two 16, and connecting component three 14 are all L-shaped connecting plates.

[0030] Specifically, the hot pressing actuator 15 includes a rotatable polygonal roller, on which heating elements 151 and cooling elements 152 are respectively mounted on different prismatic surfaces. The polygonal roller is driven to rotate by a rotary drive mechanism, so that the heating and cooling elements can act alternately on the working position, realizing the heating and pressing of the elastic band and fabric layers and subsequent cooling and shaping, which significantly improves the stability of the joint and the product quality.

[0031] In another embodiment, different structures can be used to achieve vertical clamping and horizontal movement of the vertical clamping mechanism. The lifting drive assembly 10 and the horizontal drive assembly 6, which are composed of telescopic cylinders, can also be replaced by electric cylinders, hydraulic cylinders, electric push rods, etc.

[0032] In addition to using a guide rail slider module to achieve horizontal guidance of the vertical clamping mechanism, a lead screw and nut assembly can also be used for guidance, which can accomplish the same guiding function.

[0033] The working principle and process of the hot pressing device used in this application for stretching and pressing elastic bands at the waist and cuffs are briefly described below.

[0034] First, the two ends of the elastic band 11 are placed between the lower clamping member 8 and the upper clamping member 9 of the two clamping units, respectively. The first horizontal drive assembly is activated, driving the upper clamping member 9 to descend, clamping the two ends of the elastic band together with the lower clamping member 8. The horizontal drive assembly 6 is activated, its movable end extending or shortening, driving the two clamping units connected to its two ends to move horizontally in opposite directions along the guide assembly. Since one clamping unit is fixed to the fixed end of the guide assembly and the other clamping unit is connected to the sliding member 5, the action of the horizontal drive assembly 6 mainly drives the clamping unit connected to the sliding member to move, thereby increasing or decreasing the horizontal distance between the two clamping units. By controlling the stroke of the horizontal drive assembly, the clamped elastic band 11 can be precisely stretched to the required predetermined length.

[0035] The fabric is positioned and placed over the stretched elastic band to be pressed, and positioned on the hot press anvil 2. The polygonal roller of the hot press actuator 15 rotates under the drive of the rotary drive mechanism, causing the heating element 151 to press against the layer of elastic band and fabric for heat fusion bonding. Subsequently, the roller continues to rotate, causing the cooling element to press against the just-pressed position for rapid cooling and shaping reinforcement, completing one pressing cycle. The clamping unit releases the elastic band, removes the semi-finished product, and the device resets to begin the next work cycle.

[0036] The core function of this device is to precisely clamp both ends of the elastic band, controllably stretch the elastic band to a set length, and firmly press the stretched elastic band and fabric together through hot pressing and cooling to form a semi-finished cuff or waistband.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
