[0002] Electric heating fabric is a type of fabric that is heated by an electric current, generating heat when electricity is applied. It is used for purposes such as warmth, heating, or physiotherapy. This fabric not only provides immediate warmth but also maintains a lightweight wearing experience, while possessing good breathability and water resistance, meeting people's diverse needs in cold weather.

[0003] Currently, the preparation of electric heating cloth is still mostly still in the manual production stage. Due to its complex internal structure, which includes multiple components such as conductive fibers, heating elements, and insulation layers, the installation sequence of each component is crucial during the production process, requiring the coordination of multiple processes.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] like Figures 1 to 7The electrically heated cloth continuous forming device shown is arranged in an assembly line and includes the following stations in sequence: electrode layer attachment station 1, lower adhesive film attachment station 2, silver paste coating station 3, carbon film attachment station 4, upper adhesive film attachment station 5, upper lining cloth attachment station 6, hot pressing forming station 7, and inspection station 8. Electrode layer attachment station 1 is used to automatically attach the first electrode layer 02 and the second electrode layer 03 to both ends of the lower lining cloth 01; lower adhesive film attachment station 2 is used to automatically attach the lower adhesive film 04 to the lower lining cloth 01 between the first electrode layer 02 and the second electrode layer 03; silver paste coating station 3 is used to automatically attach the first electrode layer 02 to the lower lining cloth 01 between the first electrode layer 02 and the second electrode layer 03; and the silver paste coating station 8 is used to automatically attach the first electrode layer 02 to the lower lining cloth 01 between the first electrode layer 02 and the second electrode layer 03. Silver paste 05 is automatically coated onto the conductive areas of the first electrode layer 02 and the second electrode layer 03; carbon film attaching station 4 is used to automatically attach carbon film 06 between the conductive areas of the first electrode layer 02 and the second electrode layer 03; adhesive film attaching station 5 is used to automatically attach adhesive film 08 onto carbon film 06, the first electrode layer 02 and the second electrode layer 03; upper lining cloth attaching station 6 is used to align and attach upper lining cloth 07 onto lower lining cloth 01; hot pressing forming station 7 is used to hot press and form the semi-finished product after bonding; detection station 8 is used to measure the resistance and resistance coding of the formed electric heating cloth, and to sense the temperature of the red-hot area.

[0054] Among them, a lower lining fabric conveying assembly 9 is provided across each workstation to convey several cut lower lining fabrics 01 through the base fabric to each workstation; the lower lining fabric conveying assembly 9 includes an unwinding roller and a winding roller for driving the base fabric conveying, and multiple material feeding platforms 91 set in the processing area of ​​each workstation to support the base fabric.

[0055] In this invention, a base fabric is wound on a unwinding shaft, and several cut underlay fabrics 01 are distributed on the base fabric. One end of the base fabric is pulled and wound by the winding shaft, so that the base fabric between the two spans multiple feeding platforms 91 at each station. The electrode layer attaching station 1, the under-adhesive film attaching station 2, the silver paste coating station 3, the carbon film attaching station 4, the upper adhesive film attaching station 5, the upper underlay fabric attaching station 6, the hot pressing forming station 7, and the inspection station 8 are set independently. During the operation, the equipment executes the process precisely, and each station is set up in an assembly line to process the underlay fabrics 01 conveyed on the base fabric one by one, finally obtaining the finished electric heating cloth.

[0056] In this invention, each workstation is completed automatically by the equipment, reducing errors caused by manual operation and effectively ensuring the consistency of product quality. Furthermore, each workstation adopts an assembly line design, which can complete specific processes sequentially, effectively avoiding process omissions or errors and reducing the scrap rate. The continuous conveying of the base fabric through the unwinding and rewinding rollers enables the uninterrupted preparation of the electric heating fabric, greatly improving production efficiency and meeting the needs of large-scale production.

[0057] In this invention, each workstation is set up independently and can be adjusted or expanded according to production needs to adapt to the production of electric heating cloth of different specifications or functions; by adjusting the equipment parameters of each workstation, the production of different types of products can be quickly switched, improving production flexibility.

[0058] In a preferred embodiment of the present invention, a plurality of through-hole groups 91a are regularly distributed in the two end regions of the material feeding platform 91, and a negative pressure zone 91b is provided below the plurality of through-hole groups 91a. Through the negative pressure, the plurality of through-hole groups 91a adsorb and position a section of base fabric conveyed to the work station.

[0059] Adsorption positioning ensures that the base fabric remains flat and in a fixed position throughout the conveying process, preventing errors in subsequent processes caused by fabric shifting or wrinkling. This positioning method ensures that the base fabric maintains a consistent position and state throughout the processing at each station, thereby improving the stability of the production process and the consistency of product quality.

[0060] In this invention, each workstation is set independently, and the upper surface of the feeding platform 91 on each workstation is located on the same horizontal plane. The distance between two adjacent workstations may cause the base fabric to lose its support and sag slightly. In order to ensure that the base fabric can smoothly enter the next workstation, the ends of two adjacent feeding platforms 91 are provided with arc-shaped guide plates 92.

[0061] The horizontally positioned feeding platform 91 effectively prevents the base fabric from wrinkling or twisting due to height differences during transport, ensuring that the base fabric remains flat at all times. The arc-shaped guide plate 92 guides the drooping base fabric smoothly into the feeding platform 91, preventing the base fabric from rubbing against or getting stuck on the edge of the platform. In addition, the arc-shaped guide plate 92 can disperse the tension of the base fabric, reduce the stretching or wear caused by sudden changes in direction, and extend the service life of the base fabric.

[0062] The material feeding platform 91 of this invention is set on one side of each workstation, and the other side is the material preparation area. The conveying component located between the material feeding platform 91 and the material preparation area transfers the parts to the lower lining fabric 01. However, during the conveying process, the base fabric is prone to offset in the direction perpendicular to the conveying direction, which causes the lower lining fabric 01 to fail to reach the designated position accurately, making it difficult to control the product quality. In order to solve this problem, the material feeding platform 91 is provided with centering adjustment components 10 at both ends along the conveying direction. The centering adjustment components 10 include a bridge plate 101 flush with the material feeding platform 91, a first limiting member 102 and a second limiting member 103 set on the bridge plate 101, and a driving component 104 for driving the first limiting member 102 and the second limiting member 103 to move closer or further away from each other in the direction perpendicular to the conveying direction.

[0063] By adjusting the distance between the first limiting member 102 and the second limiting member 103 through the drive component 104, the slight fluctuations of the base fabric during the conveying process can be accommodated. This dynamic adjustment mechanism can correct the positional deviation of the base fabric in the direction perpendicular to the conveying direction in real time, ensuring the precise alignment of the base fabric on the feeding platform 91. Consequently, the components can be accurately placed at the designated position of the lower lining fabric 01, avoiding installation errors caused by base fabric offset, and significantly improving the consistency of product quality.

[0064] The spacing between the equipment at each workstation causes the base fabric to sag slightly due to lack of support. When the base fabric is pulled and moved again, the equipment needs to straighten the sag before it can be properly pulled and moved on the feeding platform 91. This causes a delay in the movement of the base fabric at each workstation, affecting processing efficiency and making it difficult to ensure the positioning accuracy of the lining fabric to be processed at each workstation. To solve this problem, as a preferred solution, an auxiliary traction component 11 is provided at the discharge end of the feeding platform 91, including an active roller 111, a driven roller 112, a rotary drive component 113, and a linear drive component 114. The linear drive component 114 drives the driven roller 112 to move vertically toward the active roller 111, so that the rubber wheels at both ends of the driven roller 112 clamp the edge of the base fabric with the active roller 111. The rotary drive component 113 drives the active roller 111 to rotate, providing auxiliary traction for the base fabric.

[0065] Specifically, a support frame is provided at the discharge end of the feeding platform 91. The active roller 111 is installed inside the support frame, and its upper surface is flush with the feeding platform 91. A suspension is provided directly above the active roller 111. The driven roller 112 is installed inside the suspension. The linear drive component 114 is installed above the support frame, and its drive end is connected to the suspension. The driven roller 112 includes an intermediate roller and rubber rollers installed at both ends of the intermediate roller. The two ends of the intermediate roller are rotatably connected to the suspension via bearings. The two rubber rollers are fixed to the intermediate roller. After the previous lining fabric 01 completes processing at this station, the auxiliary traction component 11 is used to pull the base fabric, so that the next lining fabric 01 moves to the processing area of ​​this station to continue processing. Preferably, the rotary drive component 113 is a motor, and the linear drive component 114 is a cylinder, but it is not limited to the above drive forms.

[0066] In this invention, the clamping action of the driving roller 111 and the driven roller 112 enables direct traction of the base fabric, eliminating the need for conveying waiting time and significantly improving the conveying efficiency of the base fabric between various workstations. Furthermore, the cooperation of the linear drive 114 and the rotary drive 113 precisely controls the position and movement of the driven roller 112 and the driving roller 111, thereby accurately controlling the movement of the lower lining fabric 01 and effectively ensuring the accuracy of its positioning. In addition, the linear drive 114 can adjust the gap between the driven roller 112 and the driving roller 111, allowing it to adapt to base fabrics of different thicknesses, enhancing the versatility and flexibility of the equipment.

[0067] As a preferred embodiment, a distance sensor is provided between two adjacent feeding platforms 91. The distance sensor is used to detect the sag distance of the base fabric in real time, and the auxiliary traction component 11 can dynamically adjust the traction speed according to the sag distance detected by the distance sensor at the feeding end of the feeding platform 91. In this way, the auxiliary traction component 11 can ensure that the base fabric maintains appropriate tension during the conveying process, avoiding problems caused by sag or overstretching. At the same time, adjusting the traction speed in real time according to the actual state of the base fabric can effectively avoid conveying delays or jamming, thereby significantly improving overall production efficiency. In the specific process of traction speed adjustment, the sag distance detected by the sensor is input as a feedback signal to the PID controller. The PID controller calculates the adjustment amount of the traction speed according to the set target value, which is the ideal tension state of the base fabric, and sends the adjustment command to the driver of the traction motor, thereby achieving high-precision dynamic adjustment and ensuring that the base fabric maintains appropriate tension during the conveying process.

[0068] As a preferred embodiment, in this invention, auxiliary traction components 11 are provided at each station between the unwinding roller and the winding roller to achieve segmented traction, so that the base fabric can be processed sequentially starting from the first station without having to pull the base fabric directly to the winding roller. This reduces the waste at the end of the base fabric caused by the traction of the winding roller, while ensuring the maximum utilization rate of the base fabric.

[0069] In this invention, the electrode layer attaching station 1 is provided with a first attaching fixture 1a and a second attaching fixture 1b in sequence along the conveying direction of the base fabric; the first attaching fixture 1a is used to attach the first electrode layer 02 to one end of the lower lining fabric 01; the second attaching fixture 1b is used to attach the second electrode layer 03 to the other end of the lower lining fabric 01; wherein the first electrode layer 02 or the second electrode layer 03 adopts a single flexible electrode sheet, a combination of two flexible electrode sheets, or a combination of multiple flexible electrode sheets.

[0070] By dividing the electrode layer attachment station 1 into a first attachment fixture 1a and a second attachment fixture 1b, the first electrode layer 02 and the second electrode layer 03 can be accurately attached respectively, ensuring that the position of the electrode layer on the lower lining cloth 01 is more accurate, thereby improving the consistency of product quality; while the electrode layer composed of multiple flexible electrode sheets is attached to the lower lining cloth 01 in an assembled form to adapt to different product requirements.

[0071] In the preferred embodiment, a preheating heating plate 93 is provided on the feeding platform 91 located at the upper lining attaching station 6, which is used to preheat the upper adhesive film 08 and the lower adhesive film 04 on the lower lining 01 before the upper lining 07 is attached.

[0072] Preheating allows the upper adhesive film 08 and lower adhesive film 04 on the lower lining fabric 01 to reach a more suitable temperature, so that when the upper lining fabric 07 is laminated, the upper adhesive film 08 can better adhere to the upper lining fabric 07, reducing the generation of bubbles and wrinkles, and improving the flatness and firmness of the lamination; in addition, preheating allows the upper adhesive film 08 and lower adhesive film 04 to reach part of the curing temperature in advance, reducing the heating time in the subsequent hot pressing process, thereby improving production efficiency.

[0073] In a preferred embodiment of the present invention, a coding mechanism 12 is provided before the electrode layer attachment station 1 to perform coding and positioning on several underlay fabrics 01 on the base fabric; a barcode scanner is provided at each station to determine the position of the underlay fabric 01 to be processed by scanning the barcode. The coding mechanism 12 pre-prints barcodes on the underlay fabrics 01 on the base fabric before processing, and the barcode scanner quickly reads the barcode information at each station, thereby achieving accurate positioning and rapid identification of the underlay fabrics 01. This automated information processing method significantly reduces manual operation time and improves production efficiency. By recording the position and processing status of each underlay fabric 01 by the barcode scanner, a complete product production history can be constructed, facilitating the traceability of later quality issues. This data recording method provides strong support for the transparency of the production process and quality control.

[0074] The forming device in this invention also includes a receiving station 13, which includes a peeling plate disposed at the discharge end of the inspection station 8 and a receiving box for conveying and storing the finished electric heating fabric peeled from the base fabric. The receiving station 13, through the peeling plate and the receiving box, realizes the automatic collection and storage of the finished product, reduces manual intervention, and significantly improves the receiving efficiency.
