Description

Technical Field

[0001] This invention belongs to the field of printing machine technology, and in particular relates to a novel medium-based printing equipment and its preparation process. Background Technology

[0002] Printing is a process of applying patterns to textiles using dyes or pigments. Printing can be categorized into fabric printing, yarn printing, and thread printing, with fabric printing being the most common.

[0003] With economic development, the textile industry has gradually become saturated. In order to seek new development directions and achieve new economic growth, the textile industry has also innovated and implemented new industrial reforms. New media printing technologies have emerged, such as eco-friendly printing technology, foam printing technology, luminous printing technology, color-changing printing technology, and other new printing technologies. Among them, eco-friendly textile printing technology is widely used, which includes digital inkjet printing technology, electrostatic electronic printing technology, and transfer printing technology.

[0004] Currently, the general printing process for new media methods is as follows: warp knitting → pre-drying → pre-conditioning → printing → steaming → washing → dehydration → stretching and setting → finishing → finished product. While the printed fabrics produced using this process have good forming effects, for some high-grammage fabrics, poor ink penetration during printing affects the quality of the finished product. The conventional method involves setting up two parallel printing machines. After the high-grammage fabric is printed once, it is then transported to the next printing machine for a second printing. While this can compensate for poor ink penetration, it has several drawbacks. First, the increased number of machines increases purchase costs, impacting the factory's economic efficiency. Second, it requires precise positioning of the fabric during transport from one printing machine to the next. Even slight misalignment during transport can lead to overlapping prints and blurred patterns, increasing dye and chemical consumption and production costs, and also hindering the production process, thus failing to meet the factory's production needs. Summary of the Invention

[0005] This invention addresses the technical problems existing in the printing process of some high-grammage fabrics in the above-mentioned existing printing equipment. It proposes a new type of medium-method printing equipment and preparation process that is reasonably designed, simple in structure, easy to process, and can improve the functionality of the equipment. It is also convenient to make adjustments for the adaptability of fabrics of different specifications, especially the penetration effect of printing ink on the fabric. On the one hand, it reduces the amount of dyes and chemicals used and saves production costs. On the other hand, it fully improves the forming effect of the fabric, speeds up the work process, and effectively meets the production and processing needs in the factory.

[0008] Preferably, the first lifting drive mechanism includes a lifting sleeve, a lifting rod is provided inside the lifting sleeve, a first worm gear is provided at the lower end of the lifting rod, a first transmission rod is provided on the housing located below the first lifting drive mechanism, and a first worm is provided on the outer side of the first transmission rod and meshes with the first worm gear.

[0009] Preferably, a scraping mechanism is also provided between the two lifting plates. The two scraping mechanisms are arranged symmetrically at the center and are located above the pressure roller and the paint roller, respectively. The scraping mechanism includes a rotating support rod. A rotating frame with a π-shaped design is provided on the outside of the rotating support rod and can rotate together with the rotating support rod. A scraper is provided below the rotating frame. A worm gear transmission assembly is provided on the support rod located on one side of the lifting plate to facilitate the rotation of the rotating support rod.

[0010] Preferably, the conveying mechanism includes an L-shaped plate, with an abutting roller, a carrying roller, and a limiting roller arranged sequentially from left to right between the two L-shaped plates. An abutting roller is arranged below the abutting roller and the carrying roller. A second lifting drive mechanism is arranged below the L-shaped plate, and a matching roller is arranged at the corner of the screen near the conveying mechanism.

[0011] Preferably, a receiving roller is provided at one corner of the screen near the washing mechanism. The washing mechanism includes a concave mounting frame. A third lifting drive mechanism is provided inside the mounting frame. A triangular plate that can be adjusted vertically is provided below the third lifting drive mechanism. A receiving roller for receiving the printed fabric is provided at the upper corner of the triangular plate. A pressing roller for pressing down the printing guide belt is provided below the triangular plate. A washing tank is provided inside the box located below the washing mechanism.

[0012] Preferably, a lifting roller that can be adjusted vertically is provided on the housing located on one side of the washing mechanism, and a wiping roller is provided on the housing located below the lifting roller.

[0013] As a preferred embodiment, a novel medium-based printing preparation process, using a novel medium-based printing equipment, includes the following steps:

[0014] S1: First, install the printing guide belt. The installation position of the printing guide belt is described as follows: it is installed on a drive roller and runs around from below the coating roller and pressure roller toward the conveying mechanism. The printing guide belt runs from below the limiting roller to the carrying roller, then passes between the abutting roller and the abutting roller and runs around from below the mating roller. After passing the screen, it runs around to the receiving roller, then around below the downward pressure roller, and then runs around to another drive roller and is led out and connected to the other end of the printing guide belt. The installation length of the printing guide belt is greater than the length of one loop.

[0015] S2: The pre-formed blank fabric to be printed is placed on the printing guide belt. First, it is guided out according to the upper conveying position of the printing guide belt until the blank fabric is separated from the printing guide belt by the washing mechanism and exported.

[0016] S3: Control the operation of the printing guide belt to transport the blank fabric. When the fabric passes through the cleaning mechanism, control the drive motor to drive the cleaning scraper to clean the fabric surface in a gentle brushing manner to remove small impurities.

[0017] S4: When the fabric passes through the scraping mechanism, the feeding mechanism controls the colorless paste to drip between the coating roller and the pressure roller. As the coating roller and the pressure roller rotate, the colorless paste is scraped onto the fabric. At the same time, the colorless paste is pressed down to penetrate into the fabric. During this process, the position of the scraping mechanism is adjusted in time to scrape off the excess paste on the coating roller and the pressure roller, and then collect and discharge it. In addition, the position of the lifting plate is adjusted according to the different types of fabric to adjust the gap between it and the printing guide belt, so as to achieve different downward pressure.

[0018] S5: When a blank fabric with colorless paste is scraped and passed through the conveyor mechanism, the position of the conveyor mechanism can be freely adjusted according to the type of fabric so that the tension effect of the fabric during the exit process is changed when it is wrapped on the mating roller.

[0019] S6: The fabric guided by the matching roller is printed when it passes through the screen. The printed fabric is then guided out along with the printing guide belt. The printed fabric is wrapped around the receiving roller and then guided out by the lifting roller. The printing guide belt is wrapped around the bottom of the pressure roller and then guided to the bottom of the box by the drive roller.

[0020] S7: The printing guide belt in S6 can be pressed into the washing tank for washing under the drive of the third lifting drive mechanism. After washing, the printing guide belt can be wiped by the wiping roller.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] 1. This invention provides a novel medium-based printing equipment and preparation process. A cleaning mechanism pre-cleans the surface of the fabric being transported to the equipment, ensuring its cleanliness and facilitating subsequent printing. A scraping and feeding mechanism allows for the export of colorless paste, while the scraping mechanism evenly coats the paste onto the fabric, improving its permeability and ensuring sufficient penetration of the printing ink. This enhances the printing process, improves efficiency, and guarantees quality. The conveying mechanism, in conjunction with the scraping mechanism, allows for adjustable pressure during the paste penetration process, ensuring thorough fabric penetration. This device also improves the conveying process of fabrics, ensuring smooth operation and meeting usage requirements. The washing mechanism separates the fabric from the printing guide belt, facilitating the removal of the finished product, and cleans the printing guide belt, ensuring its cleanliness and preventing it from affecting subsequent fabric transport, thus improving the work process. The device is rationally designed, simple in structure, easy to process, and enhances its functionality. It allows for adaptation to different fabric specifications, particularly improving the penetration of printing ink into the fabric. This reduces the amount of dyes and chemicals used, saving production costs, while significantly improving the fabric's forming effect, thus accelerating the work process and effectively meeting the production and processing needs of the factory.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Examples, such as Figures 1 to 7As shown, a novel media printing device includes a printing device body, which comprises a housing 1. Drive rollers 2 are arranged on both the left and right sides of the housing 1. Printing guide belts 3, which transport the printed fabric, are mounted on the drive rollers 2. A stand 4 is mounted on one side of the housing 1. A printing column 5, which is rotatable and adjustable and located above the geometric center of the housing 1, is mounted on one side of the stand 4. A longitudinally movable squeegee 6 is mounted below the printing column 5. Spreading plates 7 are located on both sides of the squeegee 6. A screen 8 is also mounted below the printing column 5. The above-mentioned devices are all conventional and commonly used techniques in existing printing equipment and are readily understood by those skilled in the art. The specific working principle and method are not elaborated here; this embodiment aims to solve the problem of poor coloring effect of printing ink on fabrics, that is, to increase the permeability of the fabric and provide convenient conditions for subsequent printing penetration. In more detail: along the fabric printing direction, the box 1 is sequentially provided with a cleaning mechanism 9 for cleaning the fabric by gently brushing, a scraping mechanism 11 for improving the penetration effect of printing ink on the fabric, a conveying mechanism 10 for facilitating smooth fabric transport, and a washing mechanism 12 for facilitating water washing of the printing guide belt 3. In more detail, the scraping mechanism 11 includes a lifting plate 111, and a first lifting drive mechanism 13 is provided below the two lifting plates 111. A pressure roller 112 and a coating roller 113 are arranged laterally between the two lifting plates 111. By controlling the operation of the first lifting drive mechanism 13, the lifting plates 111, pressure rollers 112, and coating rollers 113 can be vertically adjusted to accommodate different types of fabrics for paste application. Simultaneously, the lifting adjustment allows for adjustment of the pressure during paste penetration, ensuring complete penetration and facilitating subsequent printing on the fabric, thus meeting diverse usage requirements. Furthermore, a feeding mechanism 14 is located above the lifting plates 111. The feeding mechanism 14 includes a longitudinally placed screw moving assembly 141, with a moving end of the screw moving assembly 141 equipped with a moving... The movable plate 142 is equipped with a vertically adjustable discharge pipe 143. Specifically, the movable plate 142 is equipped with a vertical sliding component, which facilitates the vertical adjustment of the discharge pipe 143. Of course, the vertical sliding component can be driven by a drive cylinder to adjust the gap between the lower end of the discharge pipe 143 and the pressure roller 112 and the coating roller 113, thus facilitating the discharge of colorless paste. Furthermore, the screw moving component 141 drives the discharge pipe 143 to move and adjust longitudinally, so that the colorless paste is evenly discharged onto the coating roller 113 and the pressure roller 112, thus providing a prerequisite for subsequent penetration.

[0035] In the above process: the cleaning mechanism 9 cleans the surface of the fabric before it is conveyed to the equipment, ensuring its cleanliness and providing convenient conditions for subsequent printing; the scraping mechanism 11 and the feeding mechanism 14 are used to discharge the colorless paste, and the scraping mechanism 11 evenly scrapes the colorless paste onto the fabric, thereby improving the fabric's permeability to a certain extent, ensuring that the printing ink can fully penetrate the fabric, thus completing the corresponding printing work, improving the work process, and ensuring the forming quality; the conveying mechanism 10, on the one hand, can cooperate with the scraping mechanism 11 to make the pressure adjustable during the penetration of the colorless paste, ensuring its penetration onto the fabric, and on the other hand, it also improves the... The conveying process of fabrics is ensured to be smooth and meet usage requirements. The washing mechanism 12 separates the fabric from the printing guide belt 3, facilitating the unloading of the formed workpiece. It also cleans the printing guide belt 3, ensuring its cleanliness and preventing it from affecting the subsequent fabric conveying, thus improving the work process. This device is reasonably designed, simple in structure, easy to process, and improves the functionality of the equipment. It is easy to adapt to different specifications of fabrics, especially the penetration effect of printing ink on the fabric. On the one hand, it reduces the amount of dyes and chemicals used, saving production costs, and on the other hand, it fully improves the forming effect of the fabric, improves the work process, and effectively meets the production and processing needs in the factory.

[0036] To effectively clean the incoming fabric to be printed, ensuring effective penetration and guaranteeing printing quality, the cleaning mechanism 9 includes a support base 91 connected to the housing 1. A support frame 92 is mounted on the housing 1 on one side of the support base 91. A support sleeve 93 is mounted on one side of the support frame 92. An L-shaped rotating rod 94 is installed inside the support sleeve 93. A drive motor 95 is mounted on the support base 91. A rotating plate 96 is mounted at the output end of the drive motor 95. A connecting rod 97 is mounted on the rotating plate 96. A ball joint rod 98 is mounted at the other end of the connecting rod 97, and the lower end of the ball joint rod 98 is connected to the rotating rod 94. A support rod 99 is mounted above the rotating rod 94, and the end of the support rod 99 is hinged. There is a connecting rod 910, and the lower end of the connecting rod 910 is equipped with a cleaning scraper 911 with an arc shape. Specifically, when the fabric to be printed is conveyed from the printing guide belt 3, the drive motor 95 is controlled to run, so that the rotating plate 96 rotates relative to the drive end of the drive motor 95. The driving power acts on the connecting rod 97, and under the action of the ball joint rod 98, the rotating rod 94 can be driven to rotate relative to the support sleeve 93. The cleaning scraper 911 above the rotating rod 94 also rotates with it. At the same time, the cleaning scraper 911 will rotate in a semi-fan shape and act on the fabric to complete the gentle cleaning, effectively removing the possibility of small impurities on the fabric during the conveying process, fully ensuring the forming quality of the workpiece and meeting the usage requirements.

[0037] To ensure the equipment can be raised and lowered vertically, the first lifting drive mechanism 13 includes a lifting sleeve 131, within which a lifting rod 132 is installed. A first worm gear 133 is installed at the lower end of the lifting rod 132. A first transmission rod 134 is installed on the housing 1 located below the first lifting drive mechanism 13. A first worm gear 135 is installed on the outer side of the first transmission rod 134 and meshes with the first worm gear 133. Specifically, the first rotating rod receives the driving power and acts on the first worm gear 135. The first worm gear 135 rotates and meshes with the first worm gear 133, thus transmitting the driving power to... The lifting rod 132 allows it to rotate vertically relative to the lifting sleeve 131 to achieve lifting and lowering. This working principle is the same as that of the lead screw converting rotation into linear movement, which will not be elaborated further. In this way, the first lifting drive mechanism 13 can easily drive the scraping mechanism 11 to move freely vertically, thereby adjusting the position of the pressure roller 112 and the coating roller 113. This allows for pressure adjustment during the penetration process to adapt to different types of fabrics, ensuring that the colorless paste can effectively penetrate into the fabric, providing a prerequisite for the completion of subsequent printing work and meeting the usage requirements.

[0038] To avoid wasting the colorless paste used to penetrate the blank fabric, a scraping mechanism 15 is provided between the two lifting plates 111. The two scraping mechanisms 15 are arranged symmetrically at the center and are located above the pressure roller 112 and the coating roller 113, respectively. The scraping mechanism 15 includes a rotating support rod 151. A rotating frame 152 with a π-shaped design is provided on the outside of the rotating support rod 151 and can rotate together with the rotating support rod 151. A scraper 153 is provided below the rotating frame 152. A scraper 153 is provided on the support rod located on one side of the lifting plate 111. A worm gear transmission assembly 154 is provided to facilitate the rotation of the rotating support rod 151. Specifically, the worm gear transmission assembly 154 receives driving power and acts on the rotating support rod 151, causing it to drive the rotating frame 152 to rotate. This allows for adjustment of the position of the scraper 153, i.e., adjusting the gap between it and the pressure roller 112 and the coating roller 113. Thus, when a large amount of colorless paste is fed out, the scraper 153 can scrape the paste between the pressure roller 112 and the coating roller 113. To facilitate the discharge of the paste by the pressure roller 112 and its application on the fabric, a collection hood is provided inside the housing 1 located below both ends of the pressure roller 112 and the coating roller 113. This hood collects and discharges excess paste, preventing waste and saving costs. It should be further noted that since the coating roller 113 and the pressure roller 112 rotate in the same direction, the scraping mechanism 15 located above the coating roller 113 primarily scrapes off the paste as the coating roller 113 rotates outward. This ensures that the paste remains between the pressure roller 112 and the coating roller 113. For the scraping mechanism 15 above the pressure roller 112, since the paste is between the pressure roller 112 and the coating roller 113, some of the paste will be carried out with the rotation of the pressure roller 112 and then scraped onto the fabric. When the pressure roller 112 rotates, the scraping mechanism 15 can scrape off the remaining paste and guide it from both sides of the scraper 153 into the collection hood, providing convenient conditions for the collection of the paste and meeting the needs of production and processing.

[0039] To effectively coordinate with the scraping mechanism 11 to press the paste on the blank fabric, thereby improving its penetration and ensuring the printing effect, the conveying mechanism 10 includes an L-shaped plate 101. Between the two L-shaped plates 101, from left to right, are arranged abutment roller 102, a support roller 103, and a limiting roller 104. Below the abutment roller 102 and the support roller 103, a stop roller 105 is positioned. Below the L-shaped plates 101, a second lifting drive mechanism 106 is located. A matching roller 81 is positioned on one corner of the screen 8 near the conveying mechanism 10. The components of the second lifting drive mechanism 106 are the same as those of the first lifting drive mechanism 13, and their working principle and method are the same. Both utilize the transmission between a worm gear and a worm to output lifting drive power, which then acts on the L-shaped plates 101, making their vertical position adjustable and thus adjusting the downward pressure to a certain extent. This provides a prerequisite for the penetration of colorless paste. Specifically, for blank fabric with colorless paste applied, it is guided out from the pressure roller 112, then wrapped around the carrying roller 103 under the limit of the limiting roller 104, and then passed through the space between the abutment roller 105 and the abutment roller 102. On the one hand, the fabric after this winding method can better penetrate the colorless paste. On the other hand, the position of the conveying mechanism 10 can be adjusted vertically by controlling the operation of the second lifting drive mechanism 106. In particular, it can improve the tension of the blank fabric in the area between the limiting roller 104 and the pressure roller 112 and between the abutment roller 102 and the cooperating roller 81. In other words, the height can be adjusted according to different types of fabric, thereby achieving tension in the above-mentioned areas to a certain extent. This makes the downward pressure during the penetration process adjustable, fully ensuring the forming quality of the workpiece and improving the work process.

[0040] To effectively clean the printing guide belt 3 and prevent the printing ink from affecting its cleanliness and thus the subsequent conveying process of the blank fabric, a receiving roller 82 is provided at one corner of the screen 8 near the washing mechanism 12. This provides convenient conditions for the conveying of the printing guide belt 3 toward the washing mechanism 12, and in particular, reduces the possibility of wear. Further, the washing mechanism 12 includes a concave mounting frame 121. A third lifting drive mechanism 122 is provided inside the mounting frame 121. Below the third lifting drive mechanism 122 is a triangular plate 123 that can be adjusted vertically. A receiving roller 124 is provided at the upper corner of the triangular plate 123 to receive the printed fabric. Below the triangular plate 123 is a pressing roller 125 to press down on the printing guide belt 3. A washing tank is provided inside the housing 1 located below the washing mechanism 12. Specifically, the components of the third lifting drive mechanism 122 are connected to the first lifting drive mechanism 122. Mechanism 13 is the same, and its working principle and operation are the same. It uses the transmission between the worm gear and the worm to output the lifting drive power, which then acts on the triangle plate 123. Of course, when the triangle plate 123 is lifting, the receiving roller 124 and the pressing roller 125 move up and down together. When the printing guide belt 3 passes through this mechanism, the third lifting drive mechanism 122 presses the printing guide belt 3 down into the washing tank to complete the washing work. Of course, when it descends to the maximum distance, the upper end of the receiving roller 124 is higher than the position of the screen 8 to prevent the fabric from being contaminated by the washing process and to ensure the product forming quality. It should be further explained that, considering the integrity of the printing guide belt 3, the printing guide belt 3 after washing is guided into the box 1 by the drive roller 2 on one side. In the box 1 located below the washing tank, there is also a roller that limits and guides the printing guide belt 3 to move away from the washing tank, thereby ensuring its smooth operation and fully meeting the needs of production and processing.

[0041] To further improve the rationality of the device setup, a lifting roller 16 that can be vertically adjusted is installed on the housing 1 located on one side of the washing mechanism 12. A wiping roller 17 is installed on the housing 1 located below the lifting roller 16. Specifically, for the separated printed fabric and printing guide belt 3, the printed fabric wraps around from above the receiving roller 124 to below the lifting roller 16, especially separating it from the printing guide belt 3. That is, the lifting roller 16 is raised to a relatively high position, ensuring that the printed fabric adheres to the lifting roller 16 and is fully away from the washed printing guide belt 3. The other end of the printed fabric is connected to the external receiving roller to provide convenient conditions for subsequent production processing. After being washed again, the printing guide belt 3 continues to be conveyed in the housing 1. The wiping roller 17 is installed to wipe the washed printing guide belt 3 to ensure its cleanliness and dryness, providing convenient conditions for the subsequent fabric conveying and effectively meeting the usage requirements.

[0042] To develop a novel medium-based printing process, a novel medium-based printing device is used for preparation, including the following steps:

[0043] S1: First, install the printing guide belt 3. The installation position of the printing guide belt 3 is described as follows: it is installed on a drive roller 2 and extends from below the coating roller and pressure roller 112 toward the conveying mechanism 10. The printing guide belt 3 extends from below the limiting roller 104 to the carrying roller 103, then passes between the abutting roller 102 and the abutting roller 105 and extends from below the mating roller 81. After passing the screen 8, it extends to the receiving roller 82, then extends below the downward pressure roller 125, and then extends to another drive roller 2 for output and is connected to the other end of the printing guide belt 3.

[0044] Specifically, the installation length of the printing guide belt 3 is greater than the length of one loop. In other words, the length of the printing guide belt 3 is adapted to the maximum movement position of each device. Of course, a mechanism for assisting in tensioning the printing guide belt 3 can also be set up inside the housing 1. This technology is a mature and commonly used technology. The specific selection of the tensioning mechanism can be effectively known by those skilled in the art, and will not be elaborated here. In this way, the rationality of the device is improved to a certain extent, and the effect of use is guaranteed.

[0045] S2: The pre-formed blank fabric to be printed is placed on the printing guide belt 3. First, it is guided out according to the upper conveying position of the printing guide belt 3 until the blank fabric is separated from the printing guide belt 3 at the washing mechanism 12 and exported.

[0046] Specifically, in the fabric printing process direction, the fabric is laid flat on the printing guide belt 3 to facilitate the printing work. Then the two are separated at the washing mechanism 12. The printed fabric is collected by the external collection roller or conveyed to the next processing area. The printing guide belt 3 moves back and forth between the drive rollers 2 to ensure the subsequent production and processing work.

[0047] S3: Control the operation of the printing guide belt 3 to transport the blank fabric. When the fabric passes through the cleaning mechanism, control the drive motor 95 to drive the cleaning scraper 911 to clean the fabric surface in a light brushing manner to remove small impurities.

[0048] S4: When the fabric passes through the scraping mechanism 11, the feeding mechanism 14 controls the colorless paste to drip between the coating roller 113 and the pressure roller 112. As the coating roller 113 and the pressure roller 112 rotate, the colorless paste is scraped onto the fabric. At the same time, the colorless paste is pressed down to penetrate into the fabric. During this process, the position of the scraping mechanism 15 is adjusted in time to scrape off the excess paste on the coating roller 113 and the pressure roller 112 and collect it out. In addition, the position of the lifting plate 111 is adjusted according to the different types of fabric to adjust the gap between it and the printing guide belt 3, so as to achieve different pressing pressures.

[0049] Specifically, the fabric to be printed is laid flat on the printing guide belt 3. The colorless paste is scraped onto the fabric using the established scraping mechanism 11 to fully saturate the yarn. This improves the penetration of the subsequent printing ink to a certain extent. Fabrics processed in this way, especially high-grammage fabrics, can avoid the need for two printing passes due to poor penetration, thereby improving the printing production efficiency and ensuring the quality of the finished product.

[0050] S5: When the blank fabric with colorless paste is scraped and passed through the conveying mechanism 10, the position of the conveying mechanism 10 can be freely adjusted according to the type of fabric, so as to change the tension effect of the fabric during the output process when it is wrapped on the mating roller 81.

[0051] S6: The fabric led out by the cooperating roller 81 is printed when it passes through the screen 8. The printed fabric is led out together with the printing guide belt 3. The printed fabric is wrapped around the receiving roller 124 and then led out by the lifting roller 16. The printing guide belt 3 is wrapped around the lower pressure roller 125 and then guided by the drive roller 2 to the lower part of the box 1.

[0052] S7: The printing guide belt 3 in S6 can be pressed into the washing tank for washing under the drive of the third lifting drive mechanism 122. After washing, the printing guide belt 3 can be wiped by the wiping roller 17.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
