Description

Technical Field

[0001] This utility model relates to the field of microfiber membrane production technology, specifically to a multi-color printing and dyeing process device for microfiber membrane. Background Technology

[0002] Microfiber membrane fabric is a membrane material made of ultra-fine fibers. As consumers increasingly demand higher product and lifestyle quality, microfiber membrane fabric will find wider application in clothing, furniture, automotive interiors, and other fields, with a very promising market prospect. However, the production of microfiber membrane fabric requires the use of dyeing and printing equipment to apply colors and patterns.

[0003] In existing multi-color printing and dyeing equipment for microfiber membrane fabrics, the color paste on the fabric is usually rolled evenly by an impression roller during printing and dyeing. Excess color paste is squeezed out, but it is difficult to collect and adheres to the equipment, wasting raw materials and requiring workers to clean it regularly, thus increasing the manufacturing cost of microfiber membrane fabrics. Maintaining the appropriate tension of the membrane fabric during the printing and dyeing process is also crucial. Excessive tension will cause the membrane fabric to stretch and break, while insufficient tension will cause the membrane fabric to loosen, hindering the penetration of color paste on the surface of the membrane fabric and resulting in mottled and uneven printing. However, the equipment usually does not have a tension adjustment mechanism, making it impossible to adjust the tension of the membrane fabric during printing and dyeing, which reduces the production quality of microfiber membrane fabrics. Utility Model Content

[0004] The purpose of this invention is to provide a multi-color printing and dyeing process device for microfiber membrane fabric to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-color printing and dyeing process device for microfiber membrane fabric, comprising:

[0006] A frame, wherein a fixed bracket is fixedly connected to the top of the frame, a storage box is installed at the bottom of the frame, and a connecting bracket is slidably connected to the inner side of the frame;

[0007] An unwinding assembly is located at one end of the inner side of the frame, and a guide fabric assembly is located on the side away from the unwinding assembly. A dyeing assembly and an imprinting assembly are located on the inner side of the frame, and a conveyor belt is located on the outer side of the dyeing assembly and the imprinting assembly. A winding assembly is located at the other end of the inner side of the frame.

[0008] The sensor is located on the inside of the fixed frame, and the controller is located on the outside of the frame;

[0009] A drive assembly is located on the top of the fixed frame. Two sets of transmission assemblies are symmetrically arranged on the outside of the drive assembly. Tension rollers for adjusting the tension of the microfiber membrane are arranged on the outside of both sets of transmission assemblies. Two sets of guide assemblies for improving the stability of movement are symmetrically arranged on the outside of the tension rollers.

[0010] Four sponges are installed on the top of the connecting frame, and a collection component is provided on the inner side of the connecting frame;

[0011] The connecting components are located on the outside of the connecting frame, and there are two sets of them. The two sets of connecting components are provided with positioning components on their outer sides.

[0012] Preferably, the drive assembly includes a motor disposed on the top of the fixed frame, and the output end of the motor is provided with a worm gear, the outer side of which is meshed with two worm wheels.

[0013] Preferably, the transmission assembly includes a connecting seat disposed on the outside of the worm gear, a first rotating rod fixedly connected to the outside of the worm gear, a second rotating rod rotatably connected to the other end of the first rotating rod, and the other end of the second rotating rod rotatably connected to the top of the tension roller.

[0014] Preferably, the guiding assembly includes a guide block fixed to the outside of the tension roller, and the inner wall of the fixing frame is provided with a guide groove, wherein the outer side of the guide block is slidably connected to the inner side of the guide groove.

[0015] Preferably, the collection assembly includes a plurality of guide holes formed on the inner side of the connecting frame, and a filter screen is installed on the inner side of the connecting frame.

[0016] Preferably, the connecting assembly includes a fixing rod fixed to the outside of the connecting frame, and a spring is sleeved on the outside of the fixing rod.

[0017] Preferably, the positioning component includes a movable seat that slides on the outside of the fixed rod, a positioning block is fixedly connected to one side of the movable seat, and a limit groove is slidably connected to the outside of the positioning block.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a continuously rotating conveyor belt. Four sponges attached to the bottom of the conveyor belt absorb the pigment paste due to their material properties, while simultaneously cleaning the outside of the conveyor belt. As the pigment paste accumulates, it flows downwards from the inside of the sponges under its own gravity, then falls through guide holes to a filter screen below. The filter screen filters out impurities in the pigment paste, which then continues to fall downwards through the pores of the filter screen under gravity, entering the storage tank for collection. This saves raw materials and reduces the manufacturing cost of the membrane fabric. A worm gear drives a worm wheel to rotate. Since the first rotating rod is L-shaped, one end of the first rotating rod rotates with the worm wheel, while the other end moves one end of the second rotating rod by changing the rotation angle. Then, by changing the height, the second rotating rod moves downwards as a whole, and the other end of the second rotating rod moves synchronously with the tension roller. The tension roller stretches the microfiber membrane fabric to a certain extent. Once the appropriate tension range is reached, the controller shuts off the motor, and the tension roller stops moving, completing the tension adjustment. This achieves tension adjustment during the membrane fabric printing and dyeing process, improving the production quality of the microfiber membrane fabric. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, a multi-color printing and dyeing process device for microfiber membrane fabric includes a frame 1, a fixed frame 2 fixedly connected to the top of the frame 1, and a storage box 3 installed at the bottom of the frame 1 for storing recycled color paste. A drain pipe, controlled by a solenoid valve, is installed at the bottom of the storage box 3 to discharge the internal color paste. A connecting frame 19 is slidably connected to the inner side of the frame 1. An unwinding assembly 4 is located at one end of the inner side of the frame 1 for unwinding the microfiber membrane fabric. A guide assembly 5 is located on the side away from the unwinding assembly 4, consisting of a motor, two gears, and two rotating rollers. The motor drives the two gears to rotate in opposite directions, and simultaneously, the gears drive the fixedly connected rotating rollers to rotate. The microfiber membrane fabric located between two rotating rollers is guided to move along a predetermined route; the inner side of the frame 1 is provided with a dyeing component 6 and an imprinting component 7. The dyeing component 6 consists of a motor and a dyeing roller. The inner side of the dyeing roller is connected to the pigment supply system. Its surface has laser-engraved grooves for transferring pigment to the microfiber membrane fabric for dyeing. This is existing technology and will not be described in detail here. The imprinting component 7 consists of a motor and an imprinting roller. The motor drives the imprinting roller to rotate and roll the pigment on the membrane fabric evenly. The outer side of the dyeing component 6 and the imprinting component 7 is provided with a conveyor belt 20, and the other end of the inner side of the frame 1 is provided with a winding component 8.

[0028] Sensor 9, located inside the fixed frame 2, is installed inside the fixed frame 2 via a connector. It can monitor the surface tension of the microfiber membrane fabric during the printing and dyeing process. When the tension exceeds a suitable range, sensor 9 will transmit the result via a signal. This is existing technology and will not be described in detail here. A controller 10 is located on the outside of the frame 1. It is connected to sensor 9 via a signal and is used to receive the signal transmitted by sensor 9 and control other components to complete the corresponding adjustments. The drive assembly 11 is located on the top of the fixed frame 2. Two sets of transmission assemblies 12 are symmetrically arranged on the outside of the drive assembly 11. Tension rollers 13 for adjusting the tension of the microfiber membrane fabric are arranged on the outside of each set of transmission assemblies 12. Two sets of guide assemblies 14 for improving the stability of movement are symmetrically arranged on the outside of the tension rollers 13.

[0029] Sponge 15 is installed on the top of the connecting frame 19 and is fixed to the top of the connecting frame 19 by a connector. It can be removed for cleaning or replacement. Due to the characteristics of the material, it will absorb the pigment on the outside of the conveyor belt 20. There are four sponges. A collection component 16 is provided on the inside of the connecting frame 19. Two sets of connecting components 17 are provided on the outside of the connecting frame 19. Positioning components 18 are provided on the outside of the two sets of connecting components 17.

[0030] The drive assembly 11 includes a motor 111 mounted on the top of the fixed frame 2. A worm gear 112 is mounted on the output end of the motor 111. Two worm wheels 113 are meshed with the outer side of the worm gear 112. The motor 111 is connected to the controller 10 via a signal. When the motor 111 starts, it drives the two worm wheels 113 to rotate in opposite directions via the worm gear 112. The transmission assembly 12 includes a connecting seat 121 mounted on the outer side of the worm wheel 113. The connecting seat 121 is fixed to the inner bottom of the fixed frame 2, and its inner side is rotatably connected to the worm wheel 113 via a rotating shaft. A first rotating rod 122 is fixedly connected to the outer side of the worm wheel 113. A second rotating rod 123 is rotatably connected to the other end of the first rotating rod 122. The other end of the second rotating rod 123 is rotatably connected to the top of the tension roller 13. The first rotating rod 122 is L-shaped. One end of the first rotating rod 122 rotates with the worm gear 113, while the other end drives one end of the second rotating rod 123 to move by changing the rotation angle. Then, by changing the height, the second rotating rod 123 will move as a whole, moving the tension roller 13 up and down. The guide assembly 14 includes a guide block 141 fixed to the outside of the tension roller 13. The inner wall of the fixing frame 2 is provided with a guide groove 142. The outer side of the guide block 141 is slidably connected to the inner side of the guide groove 142. When the tension roller 13 moves, it will drive the guide block 141 to slide along the inner side of the guide groove 142. The guide groove 142 restricts the movement path of the tension roller 13, making it move along a predetermined route, thereby improving the stability of the tension roller 13 adjustment.

[0031] The collecting component 16 includes several guide holes 161 formed inside the connecting frame 19 for guiding the pigment paste to flow downwards; a filter screen 162 is installed inside the connecting frame 19, which can filter impurities in the pigment paste. Then, the filtered pigment paste will continue to fall downwards through the pores of the filter screen 162 by gravity, while the impurities will remain on the top side of the filter screen 162.

[0032] The connecting assembly 17 includes a fixing rod 171 fixed to the outside of the connecting frame 19. A spring 172 is sleeved on the outside of the fixing rod 171. The spring 172 can slide on the outside of the fixing rod 171. When it is compressed, the spring 172 will accumulate elastic force. When one end of it loses its limit, it will reset through the elastic force. The positioning assembly 18 includes a movable seat 181 that slides on the outside of the fixing rod 171. A positioning block 182 is fixedly connected to one side of the movable seat 181. A limiting groove 183 is slidably connected to the outside of the positioning block 182. The limiting groove 183 is opened on one side of the filter screen 162. When the movable seat 181 is pulled backward, the positioning block 182 is disengaged from the inside of the limiting groove 183. The filter screen 162 loses its limit and can be disassembled. The positioning block 182 enters the inside of the limiting groove 183. The filter screen 162 is then fixed to the inside of the connecting frame 19, completing the installation.

[0033] Working principle: In use, the unwinding assembly 4 first unwinds the microfiber membrane fabric, the guiding assembly 5 guides the microfiber membrane fabric in the device, the printing and dyeing assembly 6 transfers the color paste onto the microfiber membrane fabric for printing and dyeing, and the pressing assembly 7 rolls the color paste on the membrane fabric evenly. Excess color paste adheres to the surface of the conveyor belt 20. As the conveyor belt 20 rotates continuously, the four sponges 15 attached to the bottom of the conveyor belt 20 absorb the color paste due to the characteristics of their material, while simultaneously cleaning the outside of the conveyor belt 20. As the color paste accumulates, it is removed from the sponges 15 by its own gravity. The ink flows downwards from the inside and then falls through the guide hole 161 to the filter screen 162. After the filter screen 162 filters out impurities in the ink, the ink continues to fall downwards through the pores of the filter screen 162 by gravity and enters the inside of the storage tank 3 to complete the collection. When maintaining the device, the connecting bracket 19 can be pulled out from the inside of the frame 1 to clean or replace the sponge 15. When the filter screen 162 needs to be removed for cleaning, the moving seat 181 can be pulled back. The moving seat 181 slides along the outside of the fixed rod 171, and at the same time, it takes the positioning block 182 out of the inner side of the limiting groove 183, so that the filter screen 162 loses its limit, and then filter 162 can be removed. After cleaning, filter 162 is placed back in its original position. Then, release the moving seat 181. Spring 172 will push the moving seat 181 to reset through the accumulated elastic force, so that positioning block 182 re-enters the inner side of limit groove 183. Filter 162 is then fixed to the inner side of connecting bracket 19, completing the installation. When the microfiber membrane fabric is printed and dyed, if sensor 9 detects that the microfiber membrane fabric tension is too low, it will transmit a signal to controller 10. Then, controller 10 controls motor 111 to start according to the signal content. The worm gear 112 drives the worm wheel 113 to rotate. Since the first rotating rod 122 is L-shaped, one end of the first rotating rod 122 rotates with the worm wheel 113, while the other end drives one end of the second rotating rod 123 to move by changing the rotation angle. Then, by changing the height, the second rotating rod 123 moves downward as a whole. The other end of the second rotating rod 123 moves synchronously with the tension roller 13. The tension roller 13 causes the microfiber membrane to be stretched to a certain extent. After reaching the appropriate tension range, the controller 10 turns off the motor 111, and the tension roller 13 stops moving, thus completing the tension adjustment.
