Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric composite device for transferring adhesive dots. Background Technology

[0002] In existing technologies, fabric lamination often employs adhesive application, where adhesive is applied between two or more layers of fabric to bond them together. This method consumes a large amount of adhesive during actual use and can negatively impact the environmental friendliness of the fabric. Another method uses adhesive dot transfer, which involves applying adhesive to a flat surface and transferring it onto the fabric. This transfer method is inefficient and affects the lamination efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides an adhesive dot transfer fabric lamination device that enables rapid and uniform transfer of adhesive dots onto the fabric for fabric adhesive dot lamination with high efficiency.

A first power mechanism is mounted on the frame, driving the transfer roller to rotate. One or more sets of heating rollers are mounted at the other end of the frame. Each set of heating rollers consists of two heating rollers spaced vertically apart. A first guide roller and a second guide roller are rotatably mounted on the frame outside and below the transfer roller. An arc-shaped cooling plate is mounted on the frame between the first and second guide rollers, forming an adhesive dot transfer channel between the arc-shaped cooling plate and the circumferential sidewall of the transfer roller. A [further details about the device are missing from the original text]. The third guide roller receives one layer of fabric from the first guide roller, passes through the glue dot transfer channel and the second guide roller, and then passes between each set of hot rollers. Another layer of fabric passes around the third guide roller and then passes between each set of hot rollers. A glue tank is installed on the frame above the transfer roller, and a glue discharge pipe is installed at the bottom of the glue tank. The glue discharge pipe is arranged along the axial direction of the transfer roller, and a glue dispensing valve is installed on the glue dispensing pipe. A glue dispensing head is installed at the bottom of the glue dispensing valve, and the glue dispensing head is located above the circumferential side wall of the transfer roller. A glue pipe is installed on the glue tank, and a control valve is installed on the glue pipe. A high-pressure air pipe is installed on the glue tank to maintain a high-pressure state inside the glue tank.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1:

[0016] like Figures 1-5As shown, this utility model discloses an adhesive dot transfer fabric composite device, including a frame 1 and a transfer roller 2. The transfer roller 2 is rotatably mounted at one end of the frame 1. A first power mechanism 18 is mounted on the frame 1, which drives the transfer roller 2 to rotate. One or more sets of hot rollers 6 are mounted at the other end of the frame 1. Each set of hot rollers 6 consists of two hot rollers 6 spaced vertically apart. A first guide roller 3 and a second guide roller 4 are rotatably mounted on the frame 1 outside and below the transfer roller 2. An arc-shaped cooling plate 7 is mounted on the frame 1 between the first guide roller 3 and the second guide roller 4. The arc-shaped cooling plate 7 forms an adhesive dot transfer channel between the arc-shaped cooling plate 7 and the circumferential sidewall of the transfer roller 2. A third guide roller 5 is mounted on the frame 1 between the transfer roller 2 and the hot roller 6. Fabric 17 is input from the first guide roller 3, passes through the glue dot transfer channel and the second guide roller 4, and then passes between each group of hot rollers 6. Another layer of fabric 17 passes around the third guide roller 5 and then passes between each group of hot rollers 6. A glue tank 10 is provided on the frame 1 above the transfer roller 2. A glue discharge pipe 14 is provided at the bottom of the glue tank 10. The glue discharge pipe 14 is arranged along the axial direction of the transfer roller 2. A glue dispensing valve 15 is provided on the glue dispensing pipe 14. A glue dispensing head 16 is provided at the bottom of the glue dispensing valve 15. The glue dispensing head 16 is located above the circumferential side wall of the transfer roller 2. A glue pipe 11 is provided on the glue tank 10. A control valve 12 is provided on the glue pipe 11. A high-pressure air pipe 13 is provided on the glue tank 10 to maintain the glue tank 10 under high pressure.

[0017] In this embodiment, a set of hot rollers 6 are used to hot-press the glued fabric 17. The glue dispensing valve 15 and glue dispensing head 16 are commercially available products commonly used in the art; their specific structures are not described in detail or are not limited in any way. The glue dispensing valve 15 opens and closes intermittently, allowing the glue to be transported from the glue tank 10 through the glue outlet pipe 14 to the glue dispensing head 16, where it is intermittently output in dots. The glue dispensing head 16 is used to output the glue; it is located directly above the transfer roller 2, with the glue outlet facing the transfer roller 2.

[0018] A first guide roller 3 and a second guide roller 4 are arranged on the outer and lower sides of the transfer roller 2, and an arc-shaped cooling plate 7 is arranged between the first guide roller 3 and the second guide roller 4, forming a transfer channel between the arc-shaped cooling plate 7 and the transfer roller 2. The first power mechanism 18 is a drive motor, which is connected to the transfer roller 2 and drives the transfer roller 2 to rotate. One layer of fabric 17 is input from the first guide roller 3 into the transfer channel between the arc-shaped cooling plate 7 and the transfer roller 2, and then output from the second guide roller 4. Another layer of fabric 17 is input from the third guide roller 5. The two layers of fabric 17 are combined and conveyed between the hot rollers 6. During the process of the fabric 17 passing through the transfer channel, the adhesive dots are transferred. Specifically, the adhesive tank 10 is in a sealed state, and a high-pressure air pipe 13 is provided on the adhesive tank 10. The high-pressure air pipe 13 is connected to a high-pressure air source to provide stable pressure inside the adhesive tank 10 and provide power for the output of the adhesive. The glue tank 10 has a glue pipe 11 to replenish the glue in the tank, maintaining a stable glue level. During normal glue dispensing, the transfer roller 2 rotates at a constant speed, and the dispensing valve 15 opens and closes intermittently according to a set setting. When the dispensing valve 15 is open, the high pressure in the glue tank 10 forces the glue out through the glue pipe 14, and through the dispensing valve 15, glue dots are output from the dispensing head 16 onto the transfer roller 2. When the glue dots on the transfer roller 2 rotate to the transfer channel, they come into contact with the fabric 17 and adhere to it, thus achieving glue dot transfer. Of course, according to the actual design, the gap between the arc-shaped cooling plate 7 and the transfer roller 2 must be greater than the thickness of the fabric 17, but it needs to be less than the sum of the thickness of the fabric 17 and the height of the glue dot. That is, when the fabric 17 passes through the transfer channel, it is in contact with the glue dot, allowing the glue dot to adhere to the fabric 17. In practical use, to ensure better adhesion of the adhesive dots to the fabric 17, an arc-shaped cooling plate 7 is used to support and cool the fabric 17. When the adhesive dots come into contact with the fabric 17, one side of the fabric 17 is cooled by the arc-shaped cooling plate 7, thus lowering the temperature of the first side where the adhesive dots contact the fabric 17. Therefore, the side where the adhesive dots contact the fabric 17 is more firmly bonded, making it easier to transfer the adhesive dots to the fabric 17. The adhesive dots transferred to the fabric 17 are sandwiched between the two layers of fabric 17 during the lamination process. After entering the hot roller 6, under the heating and pressing action of the hot roller 6, the adhesive dots melt, achieving lamination between the fabric 17 layers.

[0019] The arc-shaped cooling plate 7 has a hollow structure. A cooling water inlet pipe 8 is provided at one end of the arc-shaped cooling plate 7, and a cooling water outlet pipe 9 is provided at the other end of the arc-shaped cooling plate 7. The arc-shaped cooling plate 7 is hollow inside, and cooling water is introduced into it through the cooling water inlet pipe 8 and the cooling water outlet pipe 9. The temperature of the arc-shaped cooling plate 7 is maintained by circulating the cooling water, so as to cool the fabric 17.

[0020] The transfer roller 2 is an electrically heated roller. By using an electrically heated tube for the transfer roller 2, in actual use, after the adhesive forms adhesive dots on the surface of the transfer roller 2 through the dispensing head 16, the transfer roller 2 heats the adhesive dots. Meanwhile, the other end of the adhesive dot contacts the fabric 17 and is cooled by the arc-shaped cooling plate 7. This results in localized solidification at the contact end of the adhesive dot and the fabric 17, creating a stronger bond. The heating of the adhesive dot and the end of the transfer roller 2 increases their relative temperature, making separation easier and more thorough. This achieves more stable and smooth adhesive dot transfer, improving efficiency.

[0021] Each set of hot rollers 6 has a second power mechanism 19 mounted on the frame 1 at its end, which drives the hot rollers 6 to rotate. The second power mechanism 19 at the end of the hot rollers 6 may include a gearbox and a drive motor. The drive motor drives the two hot rollers 6 to move synchronously through the gearbox. The specific structure of the gearbox is existing publicly known technology and is not limited thereto. For example, gears can be provided at the ends of the two hot rollers 6, meshing with each other. A gear is also provided at the output end of the drive motor, meshing with the gear at one end of the hot roller 6 to achieve sequential transmission of the three gears. Of course, the gearbox structure can also be other structures.

[0022] In this embodiment, the transfer roller 2 is used to quickly, stably and evenly transfer the glue dots on the transfer roller 2 onto the fabric 17, thereby achieving glue application to the fabric 17 with high efficiency and high stability.
