Abstract
Description
Technical Field
[0001] This invention relates to the field of high-speed printer technology, and more specifically, to an automatic mounting device for a high-speed printer dryer. Background Technology
[0002] With the comprehensive development of printer printhead technology, ink technology, and printing media technology, printers are booming towards wide-format and high-speed printing. High-speed printers have become the high-end R&D direction in the printer industry, and many aspects of printers need to be adapted and upgraded.
[0003] Among them, the printer's dryer is one of the main core functional components that needs to be upgraded.
[0004] In high-speed printing, the entire roller system operates at a faster speed, including unwinding speed, rewinding speed, printing speed, and drying speed. However, temperature and time are essential for drying results. If the dryer structure is not changed and the time is shortened, simply increasing the temperature will cause most printing media to be unable to withstand the high temperature, affecting the printing effect.
[0005] In the roller system, the simplest way to extend the drying path length is by winding the roller system. However, when the travel speed is too fast, the printed surface may need to travel a sufficiently long path to be dried. The winding process will cause the undried surface to be wound and contact the roller shaft, resulting in damage to the printed area.
[0006] Simply stretching the drying channel into a straight line would result in an excessively narrow slit through which the fabric passes, making it impossible to operate during the fabric feeding process after roll replacement. Moreover, an excessively long drying channel occupies a large processing space, making it inflexible in terms of space.
[0007] In order to resolve the contradictions among the above-mentioned issues and enable the fabric feeding, drying path, drying efficiency, and printing speed to coexist in a coordinated manner, it is urgent to modify and upgrade the dryer.
[0008] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention
[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic drying device for high-speed printers that offers sufficient drying paths, a controllable drying process, and meets the requirements of high-speed printing.
[0010] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic fabric laying device for a high-speed printer dryer, comprising a dryer support, an L-shaped track, several drying units, a drive mechanism, a first fabric winding roller, a second fabric winding roller, and a third fabric winding roller; On both side plates of the dryer bracket, there is respectively provided a said L-shaped track. The horizontal section of the L-shaped track forms the laying section of the drying unit, and the vertical section of the L-shaped track forms the stacking section of the drying unit; The drying unit includes a housing with an open upper end, a heating rod arranged in the housing, rotating shafts arranged at both ends of the housing, rollers fixedly installed at the ends of the rotating shafts, and a gear set fixedly installed in the middle of the rotating shafts. The gear set includes a sleeve and a first gear and a second gear fixed at both ends of the sleeve. The rollers are in rolling cooperation with the L-shaped track; The driving mechanism includes a driving motor installed on one side at the corner of the L-shaped track, a first driving chain parallel to the horizontal section of the L-shaped track, and a second driving chain parallel to the vertical section of the L-shaped track. The driving motor drives the first driving chain and the second driving chain to perform rotary motions respectively through the gear set. The first driving chain is in transmission cooperation with the first gear, and the second driving chain is in transmission cooperation with the second gear; The first cloth winding roller and the second cloth winding roller are arranged outside the first drying unit. The first drying unit is located at the uppermost layer in the stacked state. The first cloth winding roller is overall higher than the upper end face of the drying unit so as to introduce the printing medium above the drying unit. The second cloth winding roller is located below the first cloth winding roller and the lower roller surface is lower than the lower end face of the drying unit so as to turn the printing medium. The third cloth winding roller is located near the vertical section of the L-shaped track in the dryer bracket so as to guide the printing medium from the second cloth winding roller.
[0011] Based on the above, the first driving chain is a rotary belt body structure evenly distributed with holes. The lower belt body of the first driving chain is higher than the height of the horizontal section of the L-shaped track. The teeth of the first gear are in transmission cooperation with the holes on the lower belt body of the first driving chain.
[0012] The teeth of the second gear are in transmission cooperation with the holes on the front belt body of the second driving chain. Based on the above, the second driving chain is a rotary belt body structure evenly distributed with holes. The front belt body of the second driving chain is located behind the vertical section of the L-shaped track.
[0013] Based on the above, a radiation plate with undulating bends is arranged in the housing of the drying unit. The heating rod is installed at the undulating low position of the radiation plate.
[0014] Based on the above, the cross-section of the radiation plate is in the shape of a "mountain".
[0015] Based on the above, in the undulating structure of the radiation plate, hollow perforations are provided at higher positions, and a hot air flow channel is formed between the radiation plate and the housing.
[0016] Based on the above, an additional heating unit is installed in the housing of the first drying unit.
[0017] Based on the above, the shell has an overall inverted trapezoidal structure that narrows at the bottom.
[0018] Based on the above, the dryer support frame is either an integrally rotatable structure or a two-section foldable structure.
[0019] Based on the above, a folding door is installed above the dryer support.
[0020] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention has the following advantages: 1. To ensure the dryer's flexibility, simplify fabric loading, and provide a longer drying channel, the entire dryer is designed as a flexibly adjustable structure consisting of several drying units. Based on the cooperation of the L-shaped track and drive mechanism, the drying units are laid flat in a row when in use, forming a long drying area above to meet the needs of high-speed printing. When not in use, the drying units are stacked vertically to save space. At the same time, during fabric loading, the printing media only needs to be wound around the first and second fabric rollers on the first drying unit, simplifying the fabric loading operation.
[0021] 2. The transmission method adopted, including the gear kit and two transmission chains, is specifically designed for this structure to ensure that the drying unit can move flexibly in the L-shaped track.
[0022] 3. In the drying unit, auxiliary structures such as radiant panels and hot air flow channels are designed. In particular, an additional heating unit is added to the first drying unit. The purpose is to improve drying efficiency and reduce the drying stroke to a certain extent. Attached Figure Description

[0032] The technical solution of the present invention will be further described in detail below through specific embodiments.
[0033] like Figures 1-8 As shown, an automatic fabric laying device for a high-speed printer dryer includes a dryer support 1, an L-shaped track 2, several drying units 3, a drive mechanism 4, a first fabric winding roller 5, a second fabric winding roller 6, and a third fabric winding roller 7.
[0034] An L-shaped track 2 is provided on each of the two side plates of the dryer support 1. The horizontal section of the L-shaped track 2 constitutes the flat section of the drying unit, and the vertical section of the L-shaped track 2 constitutes the stacking section of the drying unit.
[0035] The drying unit 3 includes a shell 31 with an open upper end, a heating rod 32 disposed in the shell 31, a rotating shaft 33 disposed at both ends of the shell 31, a roller 34 fixedly installed at the end of the rotating shaft 33, and a gear assembly 35 fixedly installed in the middle of the rotating shaft 33. The gear assembly 35 includes a sleeve 351 and a first gear 352 and a second gear 353 fixed at both ends of the sleeve. The roller 34 rolls in cooperation with the L-shaped track 2.
[0036] The drive mechanism 4 includes a drive motor 41 installed on one side of the corner of the L-shaped track 2, a first drive chain 42 parallel to the horizontal section of the L-shaped track, and a second drive chain 43 parallel to the vertical section of the L-shaped track. The drive motor 41 drives the first drive chain 42 and the second drive chain 43 to rotate through a gear kit. The first drive chain 42 is connected to the first gear 352 for transmission, and the second drive chain 43 is connected to the second gear 353 for transmission.
[0037] In this embodiment, the first drive chain 42 is a rotary belt structure with evenly distributed holes. The lower end of the first drive chain 42 is higher than the horizontal section of the L-shaped track. The teeth of the first gear 352 engage with the holes on the lower end of the first drive chain 42 for transmission.
[0038] The second drive chain 43 is a rotary belt structure with evenly distributed holes. The front belt of the second drive chain 43 is located behind the vertical section of the L-shaped track 2. The teeth of the second gear 353 are engaged with the holes of the front belt of the second drive chain 43 for transmission.
[0039] The first wrapping roller 5 and the second wrapping roller 6 are located outside the first drying unit, which is located on the top layer in the stacked state. The first wrapping roller 5 is higher than the upper surface of the drying unit 3 so as to introduce the printing medium 8 above the drying unit 3. The second wrapping roller 6 is located below the first wrapping roller 5 and its lower roller surface is lower than the lower surface of the drying unit 3 so as to turn the printing medium. The third wrapping roller 7 is located near the vertical section of the L-shaped track 2 in the dryer bracket 1 so as to guide the printing medium from the second wrapping roller.
[0040] Working principle explanation: Due to the fast stepping speed of the printing media during high-speed printing, it is difficult to adjust the drying temperature and drying time during the drying process. Therefore, it is necessary to increase the drying stroke to meet the requirements of drying time at a certain drying temperature.
[0041] Taking three drying units as an example, in the state of cloth loading or not in use, the drive mechanism 4 drives the first drive chain and the second drive chain, so that the three drying units are stored in the vertical section of the L-shaped track 2. The first cloth winding roller 5, the second cloth winding roller 6 and the third cloth winding roller 7 are located on the same side of the drying bracket 1. The cloth loading operation can be completed simply by passing the printing medium 8 from top to bottom through the three cloth winding rollers. It does not need to span the entire drying bracket, which is very convenient.
[0042] After the fabric is applied, the drive mechanism 4 drives the first drive chain and the second drive chain, so that the three drying units enter the horizontal section of the L-shaped track 2 and are arranged in a straight line. The drying surface of the drying units faces upward, forming a drying space above the three drying units. At the same time, due to the transfer of the first drying unit, the first wrapping roller 5 and the second wrapping roller 6 are also transferred to the other end of the dryer bracket 1, and the printing medium is guided to the other end, so that the printing medium spans across the drying space.
[0043] When printing begins, the dryer is turned on, and the heating rod generates heat to dry the printing media passing above it over a long path, effectively improving the drying effect. Moreover, there are no rollers supporting this span, so there is no need to worry about the printing surface being contaminated.
[0044] In other embodiments, in this embodiment, the housing 31 is integrally in an inverted trapezoidal structure with a narrowed bottom. A radiation plate 36 with undulating bends is provided in the housing 31 of the drying unit 3. The heating rod 32 is installed at the undulating low position of the radiation plate 36, and the cross-section of the radiation plate 36 is in a "mountain" shape. In the undulating structure of the radiation plate 36, hollow perforations 37 are provided at higher positions, and a hot air flow channel is formed between the radiation plate 36 and the housing 31.
[0045] To ensure the improvement of heating efficiency and the heating efficiency in the drying area, an additional heating unit 38 is installed in the housing of the first drying unit to quickly raise the temperature to a range with higher drying efficiency.
[0046] In other embodiments, the dryer support is a structure that can be rotated as a whole or a two-section foldable structure, which can be retracted when not in use to save floor space. The dryer can also be directly designed as a structure independent of the printer and transferred to other positions when not in use.
[0047] In other embodiments, a folding door is installed above the dryer support to ensure drying efficiency.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
