Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology, specifically relating to a heat sealing device for fabric processing. Background Technology

[0002] In the fabric processing industry, heat sealing technology, as a key process for achieving fabric bonding, has been continuously innovated along with industry development and market demands. Traditional direct heat sealing processes, relying solely on high temperature and pressure to bond the fabrics, have many drawbacks. Due to the lack of an intermediate adhesive medium, the bonding strength between the fabrics is insufficient, and the joints are prone to separation during product use after heat sealing, significantly affecting the product's durability and limiting its application in scenarios requiring high strength.

[0003] To overcome these challenges, the adhesive-coated heat sealing process was developed. This process significantly improves the bonding strength between fabrics by applying adhesive between them. However, traditional adhesive application methods suffer from insufficient uniformity in adhesive application, leading to inconsistent heat sealing results and adhesive waste. Furthermore, conventional heat sealing equipment lacks precision in pressure and temperature control, making it difficult to ensure that the fabric is subjected to stable and suitable high temperature and pressure during heat sealing, thus affecting the stability of the heat sealing quality. Utility Model Content

[0004] The purpose of this invention is to provide a heat-sealing device for fabric processing. Through the cooperation of the airbag, the second cylinder, and the first cylinder, the adhesive located in the second cylinder is applied more evenly to the fabric body. The area on the fabric body with adhesive is heat-sealed under high temperature and pressure, increasing the tighter bonding between the two fabric bodies during heat sealing. Compared with direct heat sealing, adhesive application can greatly improve the bonding strength between the fabrics, ensuring that the heat-sealed fabric is not easily separated during use and increasing the durability of the product.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A heat-sealing device for fabric processing includes an operating table, on which the main body of the heat-sealing device is mounted.

[0008] Furthermore, the glue application device includes a U-shaped bracket, which is rotatably connected to the lower side of the two screws. A second cylinder is rotatably connected inside the U-shaped bracket. The second cylinder has a hollow structure and multiple first glue outlet holes are opened on the second cylinder.

A servo motor is fixedly connected to one side of the U-shaped bracket, and the output end of the servo motor extends into the interior of the U-shaped bracket and is fixedly connected to one end of the second cylinder.

[0009] Furthermore, an airbag is fixedly connected to the outer side of the cylindrical shaft body, an air pump is fixedly connected to the U-shaped bracket, and a connecting pipe is fixedly connected to the lower side of the air pump.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-3 As shown, a heat sealing device for fabric processing includes an operating table 1, on which the heat sealing device body 13 is installed. An L-shaped bracket 3 is fixedly connected to the upper side of the operating table 1. The L-shaped bracket 3 is composed of a horizontal plate and a vertical plate. A height adjustment group is provided on the lower side of the horizontal plate. A glue brushing device is installed on the lower side of the height adjustment group. A circular groove is opened on the operating table 1. A roller shaft 8 is rotatably connected in the circular groove. The glue brushing device and the roller shaft 8 are opposite to each other.

[0021] In use, the fabric body 2 is placed on the operating table 1. The fabric body 2 is moved by the rotation of the glue application device and the roller 8. Since the roller 8 is connected and rotates within a circular groove, it can roll smoothly, providing power for the conveying of the fabric body 2. This allows the fabric body 2 to move in a certain direction on the operating table 1 for subsequent processing. Simultaneously, the glue application device is installed below the height adjustment group. The height adjustment group can adjust the height of the glue application device according to actual needs, adapting it to different thicknesses of fabric body 2. When the fabric body 2 is below the roller 8 and the glue application device, the glue application device... The device begins operation by evenly applying adhesive to the fabric body 2, preparing for the subsequent heat sealing process. When the adhesive-coated fabric body 2 moves to the working area of ​​the heat sealing device body 13, the heat sealing device body 13 generates heat to heat and pressurize the fabric body 2, allowing the adhesive-coated parts of the fabric body 2 to achieve heat sealing connection under high temperature and high pressure. This increases the tighter bonding between the two fabric bodies 2 during heat sealing. Compared to direct heat sealing, adhesive application can greatly improve the bonding strength between the fabrics, ensuring that the heat-sealed fabrics are not easily separated during use and increasing the durability of the product.

[0022] The main body 13 of the heat sealing device includes a heating system for generating heat to bring the material to the temperature required for heat sealing.

[0023] The main body 13 of the heat sealing device includes a pressurization system, a control system, a heat sealing mold, a transmission system, and a cooling system.

[0024] Pressurization system: During the heat sealing process, a certain pressure needs to be applied to the materials so that the heated materials can be tightly bonded together to achieve a good heat sealing effect.

[0025] Control system: Used to control various parameters of the heat sealing device, such as heating temperature, heating time, pressurization pressure, and pressurization time, to ensure the stability and consistency of the heat sealing process. The control system typically includes components such as a temperature controller, pressure controller, and time relays. Operators can input set parameters through the control panel, and the control system will automatically adjust the heating and pressurization processes according to the set values.

[0026] Heat sealing mold: Designed and manufactured according to the shape and size requirements of the heat-sealed product, it is a component that directly contacts the material and achieves heat sealing.

[0027] Transmission system: Used to transport and position materials, enabling them to accurately enter the heat-sealing area and be smoothly output after heat sealing.

[0028] Cooling system: After heat sealing, a cooling system is required to quickly cool and solidify the heat-sealed area, thereby improving production efficiency and product quality.

[0029] like Figure 1 , Figure 2 As shown, the height adjustment assembly includes two screws 4. Two threaded holes are opened on the horizontal plate, and the two screws 4 are threadedly connected to the two threaded holes. The lower side of the two screws 4 is rotatably connected to the upper side of the glue application device. A round block 5 is fixedly connected to the upper side of the screws 4. When it is necessary to adjust the height of the glue application device, rotating the round block 5 will drive the screws 4 to rotate. The screws 4 will move up and down in the threaded holes. Since the lower side of the two screws 4 is rotatably connected to the upper side of the glue application device, the up and down movement of the screws 4 will drive the glue application device to move up and down synchronously, thereby realizing the precise adjustment of the height of the glue application device to meet the glue application requirements of fabrics of different thicknesses.

[0030] like Figure 2 As shown, the glue application device includes a U-shaped bracket 6, which is rotatably connected to the lower side of two screws 4. A second cylinder 14 is rotatably connected inside the U-shaped bracket 6. The second cylinder 14 has a hollow structure and multiple first glue outlet holes are opened on the second cylinder 14. A cylindrical shaft body 16 is rotatably connected inside the second cylinder 14. A glue storage tank 9 is fixedly connected to one side of the U-shaped bracket 6. A delivery pipe 10 is fixedly connected to one side of the glue storage tank 9. The delivery pipe 10 and the glue storage tank 9 are connected. The other end of the delivery pipe 10 passes through the U-shaped bracket 6 and extends into the interior of the second cylinder 14. A servo motor 17 is fixedly connected to one side of the U-shaped bracket 6. The output end of the servo motor 17 extends into the interior of the U-shaped bracket 6 and is fixedly connected to one end of the second cylinder 14.

[0031] When in use, when the servo motor 17 is started, its output end will drive the second cylinder 14, which is fixedly connected to it, to rotate, thereby moving the fabric body 2. At the same time, the glue in the glue storage tank 9 will be transported to the internal space of the second cylinder 14 through the delivery pipe 10. Then, the second cylinder 14 will contact the surface of the fabric body 2. As the second cylinder 14 rotates, the glue inside will flow out from these first glue outlet holes, thereby coating the surface of the fabric body 2 that needs to be glued, so as to realize the glue application operation.

[0032] like Figure 2 As shown, an airbag 15 is fixedly connected to the outside of the cylindrical shaft body 16, and an air pump 12 is fixedly connected to the U-shaped bracket 6. A connecting pipe is fixedly connected to the lower side of the air pump 12. The connecting pipe passes through the U-shaped bracket 6 and extends into the airbag 15. During use, the air pump 12 will deliver gas to the airbag 15 through the connecting pipe, causing the airbag 15 to expand further, thereby increasing the pressure on the glue and causing more glue to be squeezed out from the first glue outlet, increasing the thickness and coverage of the glue application. When the glue application is completed or the glue application needs to be adjusted, the air pump 12 can extract the gas from the airbag 15 through the connecting pipe, so that the airbag 15 returns to its initial state for reuse next time.

[0033] like Figure 1 , Figure 2 As shown, a first cylinder 7 is rotatably connected to the outer side of the second cylinder 14. The first cylinder 7 has multiple second glue outlet holes, with each first glue outlet hole facing the other. The overlapping area of ​​the first and second glue outlet holes is the effective glue outlet area. In use, when multiple glue outlet holes are needed to adjust the glue dispensing amount, the first cylinder 7 is rotated to gradually align the first and second glue outlet holes. As the effective glue dispensing area increases, more glue can be squeezed out from the aligned glue outlet holes and coated onto the fabric. When the first and second glue outlet holes gradually become misaligned and the effective glue dispensing area decreases, the glue dispensing amount decreases accordingly, thereby achieving adjustment of the glue dispensing amount.

[0034] like Figure 1 , Figure 2 As shown, a valve 11 is fixedly connected to the delivery pipe 10. When in use, the valve 11 can reduce the accidental flow and unnecessary leakage of glue.

[0035] The working principle of this utility model is as follows: In use, the fabric body 2 is placed on the operating table 1. The fabric body 2 is moved by the rotation of the glue-applying device and the roller 8. Since the roller 8 is connected and rotates within a circular groove, it can roll smoothly, providing power for the conveying of the fabric body 2. This allows the fabric body 2 to move in a certain direction on the operating table 1 for subsequent processing. Simultaneously, the glue-applying device is installed below the height adjustment group. The height adjustment group can adjust the height of the glue-applying device according to actual needs, adapting it to different thicknesses of fabric body 2. When the fabric body 2 is under the roller 8 and the glue-applying device... At this time, the glue application device starts working, evenly applying glue to the fabric body 2 to prepare for the subsequent heat sealing process. When the glued fabric body 2 moves to the working area of ​​the heat sealing device body 13, the heat sealing device body 13 generates heat to heat and pressurize the fabric body 2, so that the glued parts on the fabric body 2 achieve heat sealing connection under high temperature and high pressure. This increases the tighter bonding between the two fabric bodies 2 during heat sealing. Compared with direct heat sealing, glue application can greatly improve the bonding strength between the fabrics, ensuring that the heat-sealed fabric is not easy to separate during use and increasing the durability of the product.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
