[0002] Current water-based ink printed matter drying device in order to accelerate drying process, improve drying quality, often equipped with shaking mechanism. This is because shaking can make printed matter surface air flow more fully, accelerate moisture evaporation, while preventing sticking, bubble and flow mark and other problems caused by ink not dry, to improve printing efficiency and product quality.
[0003] When the shaking mechanism is running, the contact block is a key component that directly contacts the printed matter bearing part and transmits shaking power, and bears frequent friction and impact. Since the printed matter needs to be continuously pushed by the contact block to make high-frequency reciprocating motion during the shaking process, the relative motion between the two is extremely frequent. Under this working condition for a long time, the surface of the contact block is prone to wear. Once the contact block is worn, a series of problems will be caused. On the one hand, wear will cause the contact precision between the contact block and the bearing part to decrease, making the motion trajectory of the printed matter unstable during shaking, and thus affecting the uniformity of drying. It may occur that some printed matters are over-dried, while some are under-dried, reducing the quality of printed matters. On the other hand, when the wear is serious, the contact block may not be able to normally transmit shaking power, causing the shaking mechanism to fail, the drying device to be unable to normally operate, increasing equipment maintenance cost and downtime, and affecting the continuity and efficiency of printing production.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] Please refer to Figures 1-4 The present application provides a technical solution:
[0023] Please refer to Figures 1-4 As shown in the figure, a water-based ink printed matter drying device includes a box 1, two groups of guide rollers 2 are rotatably connected to the box 1, a mounting block 3 is fixedly installed on the shaft body of the guide rollers 2 and is triangular in shape; an arc-shaped groove 6 is formed on the top corner of the mounting block 3, the arc-shaped groove 6 is arc-shaped in shape, and two fixed plates 4 are arranged on the two sides of the arc-shaped groove 6; the fixed plates 4 are installed on the two sides of the mounting block 3, a first roller 5 is rotatably arranged on the arc-shaped groove 6, and the two ends of the first roller 5 are rotatably arranged on the fixed plates 4; a mounting rod 7 is fixedly installed on the inner wall of the box 1, a return spring 8 is installed on the top of the mounting rod 7, and a top plate 9 is installed on the top of the return spring 8.
[0024] When the device is started, the two groups of guide rollers 2 start to rotate. Since the mounting block 3 is fixedly installed on the shaft body of the guide rollers 2, the mounting block 3 will rotate synchronously with the guide rollers 2. Because the mounting block 3 is triangular in shape, the position of the arc-shaped groove 6 formed on the top corner of the mounting block 3 changes constantly during rotation.
[0025] The fixed plates 4 are installed on the two sides of the arc-shaped groove 6, and the first roller 5 is rotatably arranged between the fixed plates 4 and on the arc-shaped groove 6. With the rotation of the mounting block 3, the first roller 5 rolls in the arc-shaped groove 6. This rolling mode makes the friction force between the first roller 5 and the arc-shaped groove 6 mainly rolling friction, which greatly reduces the friction coefficient compared with the sliding friction of the traditional contact block.
[0026] The mounting rod 7 is fixed on the inner wall of the box body 1, and the top reset spring 8 is connected with the top plate 9. When the guide roller 2 drives the mounting block 3 to rotate, the first roller 5 will intermittently act on the top plate 9. When the first roller 5 rotates to contact the top plate 9 and pushes the top plate 9 to move upward, the top plate 9 pushes the printed matter body 14 upward against the elastic force of the reset spring 8; when the first roller 5 rotates away from the top plate 9, the elastic force of the reset spring 8 makes the top plate 9 and the printed matter body 14 fall back. Thus, the high-frequency reciprocating shaking of the printed matter body 14 is realized.
[0027] The traditional contact block and the bearing part are in sliding friction, which is easy to wear. In the device, the first roller 5 and the arc-shaped groove 6 are mainly in rolling friction, which greatly reduces the friction and impact that the contact block, i.e. the first roller 5, and the contact part, i.e. the top plate 9, bear, prolongs the service life of the contact block, and reduces the cost of frequent replacement of the contact block due to wear.
[0028] The reduced wear keeps the contact precision between the contact block and the bearing part, i.e. the top plate 9, and the printed matter body 14, stable. In the shaking process, the printed matter body 14 can maintain a stable movement track, avoiding the problem of uneven drying caused by unstable movement track, improving the uniformity of drying of the printed matter, and ensuring the quality of the printed matter.
[0029] Due to the reduced wear of the contact block, the failure probability of the shaking mechanism is greatly reduced. The contact block will not be unable to normally transmit the shaking power due to serious wear, reducing the equipment maintenance cost and downtime, improving the continuity and efficiency of the printing production, and ensuring that the drying device can stably and efficiently operate.
[0030] Referring to Figure 3 , the two ends of the top plate 9 are provided in a circular arc shape.
[0031] The circular arc-shaped ends of the top plate 9 help the first roller 5 to more smoothly push the top plate 9 to move up and down. In the high-frequency reciprocating shaking process, it can avoid the jamming or sudden change caused by the irregular shape of the ends of the top plate 9, so that the shaking of the printed matter body 14 is more stable, which is conducive to keeping the movement track of the printed matter stable during the shaking process, further improving the drying uniformity, and improving the quality of the printed matter.
[0032] Referring to Figure 4 , the mounting rod 7 and the top plate 9 are fixedly installed with a guide telescopic rod 10, and the reset spring 8 is sleeved outside the top plate 9.
[0033] The guide telescopic rod 10 is fixedly installed between the mounting rod 7 and the top plate 9, and can provide accurate guidance for the up-down movement of the top plate 9. In the process of pushing the top plate 9 to move up and down by the first roller 5 to realize the shaking of the printed matter body 14, the guide telescopic rod 10 can limit the top plate 9 to move only along a specific straight line, avoiding the left-right deviation or shaking of the top plate 9. This helps to ensure the stability of the movement track of the printed matter body 14, and further ensures the uniformity of drying and improves the quality of the printed matter.
[0034] The guide telescopic rod 10 plays a role in connecting the mounting rod 7 and the top plate 9, making the connection between them more stable. In the high-frequency reciprocating shaking process, it can effectively disperse the force received by the top plate 9, prevent the parts from loosening or damaging due to uneven force, improve the stability and reliability of the structure of the whole device, reduce the probability of equipment failure, and reduce maintenance costs.
[0035] Referring to Figure 4 , the height of the guide roller 2 is greater than the height of the top plate 9 in the static state of the return spring 8.
[0036] It is ensured that the guide roller 2 will not collide or interfere with the top plate 9 during rotation. If the height of the guide roller 2 is less than or equal to the height of the top plate 9 in the static state of the return spring 8, the guide roller 2 may contact and hinder the normal rotation of the top plate 9 during rotation, or cause the top plate 9 to shake or be damaged due to unnecessary external force, affecting the normal operation of the whole drying device.
[0037] Referring to Figure 4 , the height of the first roller 5 is greater than the fixed plate 4, and the shape of the fixed plate 4 is circular.
[0038] The first roller 5 with a larger size has a larger contact area with the arc-shaped groove 6, and the pressure per unit area is relatively small. In the high-frequency reciprocating rolling process, the wear degree of the surface of the first roller 5 and the arc-shaped groove 6 can be effectively reduced, the service life of the first roller 5 and the mounting block 3 is prolonged, the frequency of equipment maintenance and replacement of parts is reduced, and long-term stable operation of the drying device is ensured.
[0039] The circular fixed plate 4 is matched with the cylindrical shape of the first roller 5, and the edge of the circular fixed plate 4 will not hinder the rotation of the first roller 5 during the rotation of the first roller 5. Compared with other shapes, the circular shape can ensure that the rotation of the first roller 5 at both ends is smoother, reduces the jamming or additional friction caused by the irregular shape of the fixed plate 4, and ensures the smooth operation of the shaking mechanism.
[0040] Referring to Figures 1-2 , the inner top wall of the box body 1 is fixedly installed with a drying device 11, and the drying device 11 is composed of a plurality of drying lamps which are arranged in an array.
[0041] Multiple drying lamps arranged in an array can ensure a more uniform heat distribution on the surface of the printed material 14. Drying lamps in different positions can heat different areas of the printed material separately, avoiding localized overheating or undercooling, thus improving the uniformity of drying and ensuring print quality.
[0042] Multiple drying lamps working simultaneously can provide greater heat output, accelerate the evaporation of moisture on printed materials, thereby improving drying efficiency, shortening drying time, and increasing production efficiency.
[0043] See Figures 1-2 A transmission device 12 is installed at one end of the guide roller 2, and a servo motor 13 is installed at one end of one set of guide rollers 2.
[0044] The transmission device 12 can effectively transmit the power of the servo motor 13 to each guide roller 2, ensuring that multiple guide rollers 2 can work together. By rationally designing the transmission device 12, power can be distributed to different guide rollers 2 as needed, so that they rotate at appropriate speeds and torques, thereby achieving stable conveying and precise vibration control of the printed material body 14.
[0045] It can act as a buffer and shock absorber during power transmission, reducing the impact of vibration during motor start-up, shutdown, or operation on the guide roller 2 and the entire drying device, improving the stability and reliability of the system, and avoiding damage to printed materials or poor drying effect due to vibration.
[0046] See Figure 1 The guide roller 2 is provided with the printed body 14, which is located below the drying device 11.
[0047] The drying device 11 is located above the printed matter body 14, which enables the heat emitted by the drying lamp to be transferred vertically downward to the printed matter body 14. The heat transfer path is short and concentrated, which reduces the heat loss during the transfer process and can effectively improve the drying efficiency and dry the printed matter quickly.
[0048] The printed matter body 14 is located below the drying device 11, which allows the multiple drying lamps arranged in an array in the drying device 11 to heat the printed matter body 14 more evenly, avoiding local overheating or undercooling, ensuring the uniformity of drying of the printed matter, and helping to improve the quality of the printed matter.
