Description

Technical Field

[0001] This utility model relates to the field of printing machine technology, and in particular to a magnetic table for a rotary screen printing machine. Background Technology

[0002] The magnetic table of a rotary screen printing machine is a crucial component. It relies on magnetic force to hold the fabric and other substrates in place. It typically contains magnetic materials, and through a well-designed magnetic pole distribution, sufficient attraction is generated when the fabric is placed on the magnetic table. This ensures the fabric adheres smoothly and securely to the table, preventing displacement during printing and guaranteeing that the printed pattern is accurately positioned on the fabric.

[0003] Existing technologies, such as the utility model with publication number CN2710894Y, describe an improved magnetic rod rotary screen printing machine magnetic table. This improvement is achieved through the following technical solution: the improved magnetic rod rotary screen printing machine magnetic table includes a worktable, an electromagnet, and a housing, characterized by a cooling water channel on the back of the worktable, which is a concealed pipe integrated with the worktable. According to this solution, the magnetic rod rotary screen printing machine magnetic table, due to the cooling circulating water channel on the back of the worktable, effectively prevents deformation of the worktable caused by overheating during printing and operation, as the continuously flowing circulating water absorbs and carries away the heat generated by the magnet and transferred to the worktable. This invention significantly improves the printing quality and productivity of the products. It is a beneficial improvement. However, with existing printing magnetic tables, the pigments tend to fade after printing on the fabric. When the pigments stick to the magnetic table, these residual pigments may re-adhere to the new fabric when the fabric is printed on the magnetic table, resulting in additional color spots and blemishes on the fabric surface, which damages the purity and integrity of the originally designed printing pattern.

[0004] To address the issue that when pigments adhere to the magnetic platform, these residual pigments may re-adhere to new fabrics during subsequent printing processes, resulting in additional color spots and blemishes on the fabric surface and compromising the purity and integrity of the original printed pattern, existing technologies employ reprocessing. However, this increases the operational complexity of the equipment, leading to low processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after pigments adhere to the magnetic table, these residual pigments may re-adhere to new fabrics when the fabric is printed on the magnetic table, resulting in additional color spots and blemishes on the fabric surface, which damages the purity and integrity of the originally designed printed pattern. Therefore, this invention proposes a magnetic table for a rotary screen printing machine.

[0006] The specific solution of this utility model is as follows: A magnetic table for a rotary screen printing machine includes a magnetic suction table and a drying device. A printing roller is installed on the surface of the magnetic suction table. The drying device is located on one side of the magnetic suction table. The drying device includes a first support, which is fixedly connected to the surface of the magnetic suction table. An air cylinder is fixedly connected to the upper surface of the first support, and an air pipe is fixedly connected to the lower surface of the air cylinder. An air inlet sleeve is fixedly connected to the side of the air cylinder away from the first support, and an air suction pump is fixedly connected to the side of the air inlet sleeve away from the air cylinder. By setting up the drying device, the problem of dye sticking to the magnetic suction table and being contaminated with excess dye when the fabric passes through is effectively reduced. This ensures that the printed pattern on each piece of fabric can be accurately presented according to the design, guaranteeing the stability and high standard of printing quality. At the same time, it reduces the cleaning burden of the magnetic suction table, facilitates maintenance, and increases the working efficiency of the equipment.

[0007] Preferably, a second bracket is fixedly connected to the lower surface of the air intake sleeve. The side of the second bracket away from the air intake sleeve is fixedly connected to the magnetic suction table. By setting the air intake sleeve, it can introduce outside air into the system, so that under the drive of the suction pump, the airflow can flow smoothly along the pipe, be heated by the heating wire in sequence, enter the air cylinder, and finally be sprayed onto the fabric surface.

[0008] Preferably, the inner wall of the air inlet sleeve is equipped with an electric heating wire, and the air pipe is connected to the air cylinder. By setting the electric heating wire, the electric heating wire generates heat after being energized, which can heat the airflow and make the heated airflow spray onto the fabric surface, thereby quickly removing the moisture and other volatile components in the dye on the fabric surface and promoting the dye to solidify faster.

[0009] Preferably, there are multiple air tubes arranged in a linear array, the air cylinder is hollow, and the air inlet sleeve is connected to the air cylinder. By setting up the air cylinder, the hot air flow from the heating wire first enters the air cylinder. The air cylinder is like a hot air storage chamber, which allows the hot air flow to accumulate and form a certain pressure. Then, it is evenly and powerfully sprayed onto the fabric surface through the air tubes.

[0010] Preferably, a cleaning device is provided on one side of the magnetic suction table. The cleaning device includes a mounting block, which is fixedly connected to the magnetic suction table. A circular roller is rotatably connected to the surface of the mounting block, and soft bristles are fixedly connected to the surface of the circular roller. By setting up the cleaning device, the soft bristles rub and clean the underside of the fabric, which can effectively remove impurities carried by the fabric and prevent these impurities from being carried to the magnetic suction table. If the magnetic suction table adsorbs too many impurities, its adsorption stability on the fabric will be affected. For example, uneven local adsorption force may occur, causing the fabric to shift during the printing process, affecting the accuracy and integrity of the printed pattern.

[0011] Preferably, a servo motor is fixedly connected to one side of the mounting block. The drive end of the servo motor passes through the mounting block and is fixedly connected to the roller. By setting the servo motor, the servo motor can accurately adjust the rotation speed according to actual needs through a precise control system. In the process of driving the roller to rotate to use soft bristles to rub and clean the fabric underneath, the required cleaning speed is different depending on the fabric material, thickness, and printing process requirements.

[0012] Preferably, there are two mounting blocks, and the two mounting blocks are arranged in a mirror-symmetrical manner.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention effectively reduces the amount of dye adhering to the magnetic suction table, preventing the fabric from picking up excess dye as it passes through. It ensures that the printed pattern on each piece of fabric is accurately presented according to the design, guaranteeing the stability and high standard of printing quality. At the same time, it reduces the cleaning burden on the magnetic suction table, making maintenance easier and increasing the working efficiency of the equipment. Attached Figure Description

An air cylinder 31 is fixedly connected to the upper surface of the first support 32, and an air pipe 33 is fixedly connected to the lower surface of the air cylinder 31. An air inlet sleeve 35 is fixedly connected to the side of the air cylinder 31 away from the first support 32, and an air suction pump 36 is fixedly connected to the side of the air inlet sleeve 35 away from the air cylinder 31. By setting up the drying device 3, the amount of dye adhering to the magnetic suction table 1 is effectively reduced, and the fabric is not contaminated with excess dye when passing through. This ensures that the printed pattern on each piece of fabric can be accurately presented according to the design, guaranteeing the stability and high standard of printing quality. At the same time, it reduces the cleaning burden of the magnetic suction table 1, facilitates maintenance, and increases the working efficiency of the equipment.

[0022] Furthermore, a second bracket 34 is fixedly connected to the lower surface of the air intake sleeve 35. The side of the second bracket 34 away from the air intake sleeve 35 is fixedly connected to the magnetic suction table 1. By setting the air intake sleeve 35, it can introduce outside air into the system, so that under the drive of the suction pump 36, the airflow can flow smoothly along the pipe, be heated by the heating wire 37 in sequence, enter the air cylinder 31, and finally be sprayed onto the surface of the fabric.

[0023] Furthermore, an electric heating wire 37 is installed on the inner wall of the air inlet sleeve 35, and the air pipe 33 is connected to the air cylinder 31. By setting the electric heating wire 37, the electric heating wire 37 generates heat after being energized, which can heat the airflow and make the heated airflow spray onto the fabric surface, thereby quickly removing the moisture and other volatile components in the dye on the fabric surface and promoting the dye to solidify faster.

[0024] Furthermore, there are multiple air tubes 33 arranged in a linear array. The air cylinder 31 is hollow. The air inlet sleeve 35 is connected to the air cylinder 31. By setting up the air cylinder 31, the hot air flow from the heating wire 37 first enters the air cylinder 31. The air cylinder 31 is similar to a hot air storage chamber, which allows the hot air flow to accumulate and form a certain pressure. Then, it is evenly and powerfully sprayed onto the fabric surface through the air tubes 33.

[0025] Furthermore, a cleaning device 4 is provided on one side of the magnetic suction table 1. The cleaning device 4 includes a mounting block 43, which is fixedly connected to the magnetic suction table 1. A roller 42 is rotatably connected to the surface of the mounting block 43, and soft bristles 41 are fixedly connected to the surface of the roller 42. By setting up the cleaning device 4, the soft bristles 41 rub and clean the underside of the fabric, effectively removing impurities carried by the fabric and preventing these impurities from being carried onto the magnetic suction table 1. If the magnetic suction table 1 adsorbs too many impurities, its adsorption stability on the fabric will be affected. For example, uneven local adsorption force may occur, causing the fabric to shift during the printing process, affecting the accuracy and integrity of the printed pattern.

[0026] Furthermore, a servo motor 44 is fixedly connected to one side of the mounting block 43. The drive end of the servo motor 44 passes through the mounting block 43 and is fixedly connected to the circular roller 42. By setting the servo motor 44, the servo motor 44 can accurately adjust the rotation speed according to actual needs through a precise control system. In the process of driving the circular roller 42 to rotate and use the soft bristles 41 to rub and clean the fabric underneath, the required cleaning speed varies depending on the fabric material, thickness, and printing process requirements. There are two mounting blocks 43, which are arranged in a mirror-symmetrical manner.

[0027] The working principle of this utility model is as follows: By setting up a drying device 3 and a cleaning device 4, after the printing roller 2 prints the dye onto the fabric, the suction pump 36 is started. The suction pump 36 drives the airflow into the air inlet sleeve 35. At the same time, the heating wire 37 is energized to generate heat. The airflow enters the air cylinder 31 through the heating wire 37, and then is sprayed onto the fabric surface through the air pipe 33. The heating wire 37 heats the airflow, which facilitates the solidification of the dye on the fabric and increases the working efficiency of the equipment. When the fabric passes through the magnetic suction table 1, the servo motor 44 is started, and the servo motor 44 drives... The rotating roller 42 drives the soft bristles 41 to rub and clean the underside of the fabric, reducing the amount of impurities adhering to the underside of the fabric and bringing them onto the magnetic suction table 1, which could cause the magnetic suction table 1 to become unstable. By setting up this utility model, the amount of dye adhering to the magnetic suction table 1 is effectively reduced, and the fabric will be contaminated with this excess dye when it passes by. This ensures that the printed pattern on each piece of fabric can be accurately presented according to the design, guaranteeing the stability and high standard of printing quality. At the same time, it reduces the cleaning burden on the magnetic suction table 1, making maintenance easier and increasing the working efficiency of the equipment.
