Technical Field
[0001] This invention belongs to the technical field of hot stamping agent mixing systems, specifically relating to an automatic dispensing and conveying system for adhesives in hot stamping processes. Background Technology
[0002] Hot stamping fabrics, with their rich colors, strong fashion sense, and the ability to impart special functions such as windproofing, downproofing, and fire resistance, have become one of the most popular textiles today. Traditional hot stamping processes primarily use solvent-based polyurethane as an adhesive because solvent-based polyurethane adhesives offer advantages such as low cost, uniform viscosity, good rheological properties, clean edge finishing, easy drying, and excellent fastness, giving the hot stamping fabric high abrasion resistance and washability. However, with increasingly stringent environmental protection requirements and stricter requirements for the working environment of employees in manufacturing plants, traditional solvent-based products suffer from drawbacks such as high static electricity, strong odor, high energy consumption during heat preservation and curing, and significant safety risks. Furthermore, the inherent odor remains a problem. Therefore, the traditional solvent-based polyurethane adhesive process and final product do not meet environmental protection requirements and are not considered green production. In contrast, the adhesive production process and final product fully meet environmental protection requirements and are considered green production. Therefore, improving and adopting environmentally friendly hot stamping materials is particularly important.
[0003] However, the preparation of general adhesives requires precise proportions and long-term stirring. In large-scale production, manual proportioning and stirring are inefficient in the preparation of adhesives. The ingredients need to be weighed first, then the prepared ingredients need to be placed in a mixing drum and stirred. After that, they need to be taken out and placed on the hot stamping equipment for use. The whole process is time-consuming and the labor intensity of the operators is high. Summary of the Invention
[0004] The present invention mainly addresses the technical problems existing in the prior art and provides an automatic dispensing and conveying system for adhesives in hot stamping processes.
[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: an automatic dispensing and conveying system for adhesive in hot stamping process, comprising a hot stamping feeding scraper, two material tanks and a mixing drum, wherein the hot stamping feeding scraper is a hollow structure, including a front-end adhesive application strip, the front-end adhesive application strip and the hot stamping feeding scraper are integrally formed, the front-end adhesive application strip includes two adhesive application slopes, and multiple adhesive outlet holes are equidistantly provided on the two adhesive application slopes; a feed inlet is provided at the rear end of the hot stamping feeding scraper; a feed port and a discharge port are provided at the bottom of each of the two material tanks; and a material inlet is provided at the bottom of the mixing drum. The system includes a feed pipe and a discharge pipe. Control valves are installed at the feed inlet, discharge inlet, and the openings of the feed pipe and discharge pipe. A three-way pipe connects the two feed tanks to the mixing drum. The three-way pipe includes two inlet ends and one outlet end. The two inlet ends are respectively connected to the control valves connected to the discharge inlets at the bottom of the two feed tanks. The outlet end is connected to the control valve on the feed pipe at the bottom of the mixing drum. A mixing pipe connects the mixing drum to the hot stamping scraper. One end of the mixing pipe is connected to the feed inlet on the hot stamping scraper, and the other end is connected to the control valve on the discharge pipe at the bottom of the mixing drum.
[0006] Preferably, the conveying system further includes a booster pump, and a first air inlet pipe is provided on the top of each of the two tanks and the top of the mixing drum. A first control air valve is provided on each of the first air inlet pipes, and a first booster pipe is connected between the booster pump and the first control air valves on the three first air inlet pipes.
[0007] Preferably, the conveying system further includes a pigment supply system, which includes a distributor and multiple pigment tanks. Each pigment tank has a second control air valve and a pigment inlet pipe at its top, and a pigment outlet control valve connected to its bottom. A gas distribution pipe is connected between the booster pump and the pigment supply system. The gas distribution pipe includes an air inlet and multiple air outlets. The air inlet is connected to the booster pump, and the multiple air outlets are connected one-to-one to the second control air valve at the top of each pigment tank.
[0008] Preferably, a color paste outlet pipe is connected between the distributor and each color paste tank. One end of the color paste outlet pipe is connected to the slurry control valve at the bottom of the color paste tank, and the other end is connected to the distributor. A shut-off valve is installed at the connection point between the color paste outlet pipe and the distributor.
[0009] Preferably, a distributor outlet pipe is connected between the distributor and the stirring drum, and a color paste feed control valve is provided at the upper end of the stirring drum wall. One end of the distributor storage tank is connected to the distributor, and the other end is connected to the color paste feed control valve.
[0010] Preferably, the stirring drum is equipped with a viscosity meter.
[0011] Preferably, the dispenser is equipped with a rinsing water pipe connector, which is a self-sealing connector.
[0012] Preferably, the stirring drum is equipped with a negative pressure pump, which is connected to the interior of the stirring drum.
[0013] The beneficial effects of this invention are as follows: by setting up a hot stamping feeding scraper, a material tank and a mixing drum, and using the three-way pipe connecting the tank and the mixing drum, the pre-assembled material in the tank can be proportionally transported to the mixing drum for mixing. The mixing drum is used for mixing, and the mixing pipe connecting the mixing drum and the hot stamping feeding scraper can directly pass the mixed material into the hollow hot stamping feeding scraper and directly extrude it onto the glue roller of the hot stamping machine through the glue outlet. No manual handling is required, which greatly improves the efficiency of adhesive preparation. Moreover, the pipeline transportation can greatly reduce the labor intensity of the operators.
[0014] By setting up a booster pump and applying different pressures to the material tank, different amounts of material can be extruded through the material pipe, thereby adjusting the proportions. At the same time, by using the booster pump to pressurize the mixing drum, the mixture in the mixing drum can be directly extruded through the mixing pipe, thus realizing automatic batching and conveying of the equipment.
[0015] By setting up a color paste supply system and using a booster pump to pressurize different color paste tanks, color pastes of different colors can be mixed in the mixture, thereby enabling the preparation of colored adhesives. Attached Figure Description

The bottom of the mixing drum 3 is provided with a material feed pipe 10 and a discharge pipe 11. The feed port 8, discharge port 9, material feed pipe 10, and discharge pipe 11 are connected together. A control valve 12 is installed at the inlet of pipe 11. A three-way pipe 13 is connected between the two material tanks 2 and the mixing drum 3. The three-way pipe 13 includes two inlet ends 14 and one outlet end 15. The two inlet ends 14 are respectively connected to the control valve 12 connected to the bottom discharge port 9 of the two material tanks. The outlet end 15 is connected to the control valve 12 on the material feed pipe 10 at the bottom of the mixing drum 3. A mixing pipe 16 is connected between the mixing drum 3 and the hot stamping scraper 1. One end of the mixing pipe 16 is connected to the feed port 7 on the hot stamping scraper 1, and the other end is connected to the control valve 12 connected to the bottom discharge pipe 11 of the mixing drum 3.
[0022] The conveying system also includes a booster pump 17. The top of the two tanks and the top of the mixing drum 3 are each provided with a first air inlet pipe 18. Each first air inlet pipe 18 is provided with a first control air valve 19. A first booster pipe 20 is connected between the booster pump 17 and the first control air valves 19 on the three first air inlet pipes 18.
[0023] The conveying system also includes a color paste supply system, which includes a distributor 21 and multiple color paste tanks 22. Each color paste tank 22 has a second control air valve 26 and a color paste inlet pipe 24 at its top. The bottom of each color paste tank 22 is provided with a slurry outlet control valve 25. A gas distribution pipe 27 is connected between the booster pump 17 and the color paste supply system. The gas distribution pipe 27 includes an air inlet 28 and multiple air outlets 29. The air inlet 28 is connected to the booster pump 17, and the multiple air outlets 29 are connected one-to-one to the second control air valve 26 at the top of each color paste tank 22.
[0024] Each color paste tank 22 is connected to a color paste outlet pipe 31. One end of the color paste outlet pipe 31 is connected to the color paste control valve 25 at the bottom of the color paste tank 22, and the other end is connected to the color paste distributor 21. A shut-off valve 32 is installed at the connection between the color paste outlet pipe 31 and the color paste distributor 21.
[0025] A distributor outlet pipe 33 is connected between the distributor 21 and the stirring drum 3. A color paste feed control valve 12 is provided at the upper end of the wall of the stirring drum 3. One end of the storage tank 2 of the distributor 21 is connected to the distributor 21, and the other end is connected to the color paste feed control valve 12.
[0026] The stirring drum 3 is equipped with a viscosity meter 34.
[0027] The separator 21 is equipped with a rinsing water pipe connector 35, which is a self-sealing connector.
[0028] The principle of this invention: In use, two materials, A and B, are added to the material tank 2, both of which are in a flowing state. The two material tanks 2 are pressurized in stages by the booster pump 17. Due to the different pressurization, the materials in the material tanks 2 will enter the mixing drum 3 in proportion through the three-way pipe 13. After the proportion is completed, the corresponding control valve 12 is closed. The mixed materials are stirred in the mixing drum 3. After the stirring is completed, the mixture is directly fed into the hot stamping feeding scraper 1 of the hot stamping machine through the mixing pipe 16, and extruded through the glue outlet 6 and scraped onto the glue roller.
[0029] When there is a color requirement for the adhesive, the different color paste tanks 22 are pressurized by the booster pump 17, and the color paste can be transported to the mixing drum 3 through the distributor 21 and the distributor outlet pipe 33 to increase the color of the adhesive.
[0030] Both the control valve 12 and the control air valve in the system can be operated manually or electrically. The manual valve needs to be manually closed after each material conveying is completed, while the electric valve is controlled by an external controller.
[0031] The number of material tanks 2 can be increased according to actual needs, and they are connected to the mixing drum 3 through a multi-port pipe. The number of color paste tanks 22 can also be increased or decreased according to needs.
[0032] A viscosity meter 34 is installed in the mixing drum 3. The adhesive has viscosity requirements. The discharge of the material tank 2 can be controlled in real time by the booster pump 17, thereby realizing real-time viscosity adjustment.
[0033] After using the color paste supply system, the distributor 21 and the mixing drum 3 will have residual color paste and adhesive inside. By closing the shut-off valve 32 and the corresponding control valve 12, the distributor 21, the distributor outlet pipe 33 and the mixing drum 3 can be sealed. The inside can be rinsed by connecting the water pipe with the rinsing water pipe connector 35.
[0034] Preferably, the mixing drum 3 is equipped with a negative pressure pump 35, which is connected to the interior of the mixing drum 3. After the equipment is used, the negative pressure pump 35 draws the adhesive in the hot stamping scraper 1 and the mixing pipe 16 into the mixing drum 2, thereby avoiding clogging of the hot stamping scraper 1.
[0035] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
