Description

Technical Field

[0001] This application relates to the field of printing technology, and more particularly to a drying apparatus and printing equipment. Background Technology

[0002] In digital inkjet printing, the printed paper needs to be dried. During printing, the combination of ink and pre-coating can easily lead to ink drying problems, thus requiring a drying unit to dry the printed paper. Since the temperature in the drying oven can typically reach over 800℃ (at the lamp surface) and the printing speed is high, even exceeding 180M / min, the paper may curl at the edges. In this case, some paper may come into contact with the drying lamp, and due to the high temperature of the lamp, the drying paper could easily catch fire, posing a safety hazard. Utility Model Content

[0003] This application aims to provide a drying apparatus and printing equipment to reduce the problem of paper catching fire during drying.

[0004] In a first aspect, this application proposes a drying apparatus, including a mounting frame, a drying lamp, a light-transmitting plate, and a fan. Specifically, the mounting frame includes a shelf, which encloses a drying area. The drying lamp is mounted on the shelf and faces the drying area. The light-transmitting plate is located on the side of the mounting frame closest to the drying area, with the drying lamp positioned between the shelf and the light-transmitting plate along a first direction. The first direction is the thickness direction of the shelf. The fan is located on the side of the shelf facing away from the drying area, and the shelf has several through holes communicating with the drying area.

[0005] In the above scheme, the mounting frame provides support for the drying lamps, improving their stability during the drying operation. The drying lamps face the drying area to dry the paper. A light-transmitting plate separates the drying lamps from the drying area, reducing contact between the lamps and paper even if the paper warps or jams, thus minimizing damage to the lamps and the risk of fire. The light-transmitting properties of the plate allow the lamps to dry the paper through it. A fan reduces the risk of damage to the lamps due to continuously rising internal temperatures. Simultaneously, the fan transfers heat to the drying area, and the airflow helps the paper adhere more closely to the conveyor platform, reducing warping. These features effectively reduce the risk of paper warping and jamming, thereby minimizing damage to the lamps and the risk of fire, improving the safety of paper printing.

[0006] In some embodiments, the mounting bracket further includes a top shell connected to the frame plate, and the fan is disposed on the top shell. By providing a top shell and mounting the fan on it, the stability of the fan can be improved, resulting in a more stable airflow.

[0007] In some embodiments, the drying apparatus further includes a first mounting plate and a second mounting plate, which are disposed opposite to each other on a mounting frame along a second direction. The second direction is perpendicular to the first direction. The first mounting plate has a first protruding plate and a second protruding plate protruding towards the second mounting plate, which are spaced apart along the first direction to form a first clamping space. The second mounting plate has a third protruding plate and a fourth protruding plate protruding towards the first mounting plate, which are spaced apart along a direction perpendicular to the mounting frame to form a second clamping space. One end of the light-transmitting plate is clamped in the first clamping space, and the other end is clamped in the second clamping space. The first and second mounting plates, with protrusions on them forming the first and second clamping spaces, provide a more stable mounting space for the light-transmitting plate. This mounting method allows for pull-out installation and removal of the light-transmitting plate, improving its ease of installation and removal.

[0008] In some embodiments, the drying apparatus further includes a baffle disposed on the mounting frame. The baffle faces the light-transmitting plate and is used to limit the displacement of the light-transmitting plate along a third direction. The first direction, the second direction, and the third direction are all perpendicular to each other. By providing a baffle on the mounting frame to limit the displacement of the light-transmitting plate in the third direction, the stability of the light-transmitting plate is improved.

[0009] In some embodiments, the baffle includes a first stop plate and a second stop plate, with the first stop plate extending toward the light-transmitting plate. The second stop plate includes a first portion and a second portion connected together. The first portion and the first stop plate are arranged parallel to each other and extend toward the light-transmitting plate, while the second portion is inclined relative to the first portion. A first stopping space is formed between the first stop plate and the second stop plate, which is used to restrict the displacement of the light-transmitting plate. By providing a first stop plate and a second stop plate on the baffle to form the first stopping space, the displacement of the light-transmitting plate in a third direction can be more effectively restricted.

[0010] In some embodiments, the mounting bracket is provided with a third stop plate and a fourth stop plate. Along a third direction, the third stop plate is opposite to the first stop plate, and the fourth stop plate is opposite to the second stop plate. The third stop plate extends toward the light-transmitting plate, and the fourth stop plate includes a third portion and a fourth portion connected together. The third portion and the third stop plate are parallel and extend toward the light-transmitting plate, with the fourth portion inclined relative to the third portion. A second stop space is formed between the third and fourth stop plates. Along a third direction, one end of the light-transmitting plate is disposed in the first stop space, and the other end of the light-transmitting plate is disposed in the second stop space. By providing the third and fourth stop plates in the mounting bracket to form the second stop space, it can cooperate with the first stop space to more effectively restrict the displacement of the light-transmitting plate in the third direction, reducing the reduction in the drying effect of the drying lamps due to instability of the light-transmitting plate during the drying operation, and improving drying efficiency.

[0011] In some embodiments, the first stop plate, the second stop plate, the third stop plate, and the fourth stop plate are provided with multiple ventilation holes. Providing multiple ventilation holes on the first stop plate, the second stop plate, the third stop plate, and the fourth stop plate can more effectively carry the heat from the fan to the drying area, improving drying efficiency. It can also provide more effective blowing force, allowing the paper to better adhere to the conveyor platform and reducing the occurrence of paper curling and jamming.

[0012] Secondly, this application proposes a printing apparatus, including a drying device as described in any embodiment of the first aspect and a paper feeding device, wherein the paper feeding device is disposed in the drying area. The drying device, in conjunction with the paper feeding device, can improve the efficiency of the drying operation.

[0013] In some embodiments, the drying apparatus further includes an adjustment assembly. The adjustment assembly includes a first cylinder and a second cylinder. Along a second direction, the first cylinder and the second cylinder are respectively disposed on opposite sides of the mounting frame. Along a third direction, one end of the mounting frame is hinged to the paper feeding device, and the other end is connected to the first cylinder and the second cylinder. By providing the adjustment assembly and using the cylinders to adjust the angle of components such as the drying lamp, drying efficiency can be improved. Furthermore, when drying is not required, the cylinders can be used to support the drying components, providing the paper feeding device with better operating space.

[0014] In some embodiments, the adjustment assembly further includes a first gas spring and a second gas spring. Along a second direction, the first and second gas springs are disposed on both sides of the mounting bracket and connected to the mounting bracket. The addition of the first and second gas springs to the adjustment assembly assists the pushing action of the first and second cylinders, resulting in smoother angle adjustment of the drying component and reducing the possibility of damage to parts due to angle adjustment.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0020] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0021] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0022] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0023] Firstly, this application proposes a drying apparatus 10, including a mounting frame 1, a drying lamp tube 2, a light-transmitting plate 3, and a fan 4. Specifically, please refer to... Figure 1 , Figure 2 and Figure 3 The mounting frame 1 includes a frame plate 11, which encloses a drying area 101. A drying lamp 2 is mounted on the frame plate 11 and faces the drying area 101. A light-transmitting plate 3 is located on the side of the mounting frame 1 closest to the drying area 101, with the drying lamp 2 positioned between the frame plate 11 and the light-transmitting plate 3 along a first direction X. The first direction X is the thickness direction of the frame plate 11. A fan 4 is located on the side of the frame plate 11 facing away from the drying area 101, and the frame plate 11 has several through holes 111 communicating with the drying area 101.

[0024] For the aforementioned mounting bracket 1, side plates can be added to both sides of the bracket plate 11. The bracket plate 11 and the side plates can be integrally installed or detachably installed to improve the strength and stability of the mounting bracket 1. The drying lamp tube 2 can be installed on the bracket plate 11 by means of threaded connection. Furthermore, the mounting bracket 1 can be made of high-temperature resistant alloy material to reduce the impact of the high temperature of the drying lamp tube 2 on the mounting bracket 1.

[0025] For the aforementioned drying lamp tube 2, different wavelengths of drying lamp tube 2 can be selected according to different drying scenarios to improve the drying efficiency of the drying lamp tube 2. The outer shell of the drying lamp tube 2 can be made of high-temperature resistant and thermal shock resistant materials, such as quartz. The lamp holder and wiring part can be made of flame-retardant materials such as high-temperature resistant PBT plastic, ceramics, etc., to improve the safety of the drying lamp tube 2.

[0026] Regarding the aforementioned light-transmitting plate 3, it is understood that, in order not to affect the drying operation of the drying lamp tube 2, the light-transmitting plate 3 is made of a light-transmitting material, and can be made of a high-temperature resistant material such as quartz glass. Light-transmitting plates 3 of different thicknesses can be provided according to different requirements.

[0027] For the aforementioned fan 4, due to its working environment, the fan blades can be made of heat-resistant materials such as stainless steel to reduce the impact of high temperatures on the fan 4. Furthermore, a breathable protective cover can be installed around the fan 4 to reduce the risk of exposed fan blades.

[0028] In the above scheme, the mounting frame 1 provides support for the drying lamp tube 2, improving its stability. The drying lamp tube 2 faces the drying area 101 to dry the paper. The light-transmitting plate 3 separates the drying lamp tube 2 from the drying area 101, reducing contact between the drying lamp tube 2 and the paper even if the paper curls or jams, thus reducing damage to the drying lamp tube 2 and the risk of paper ignition due to contact. The light-transmitting properties of the light-transmitting plate 3 allow the drying lamp tube 2 to dry the paper through it. The fan 4 reduces the risk of damage to the drying lamp tube 2 due to continuous rise in internal temperature. Simultaneously, the fan 4 transfers heat to the drying area 101, and the airflow helps the paper adhere more closely to the conveyor platform, reducing paper curling. Through these settings, the risk of paper curling and jamming, and consequently damage to the drying lamp tube 2 and the risk of fire due to contact with it, can be effectively reduced.

[0029] In some embodiments, please refer to Figure 1 and Figure 2 The mounting bracket 1 also includes a top shell 12, which is connected to the frame plate 11, and the fan 4 is mounted on the top shell 12. By mounting the fan 4 on the top shell 12, the stability of the fan 4 can be improved, making the airflow more stable.

[0030] In some embodiments, please refer to Figure 3 and Figure 4The drying device 10 also includes a first mounting plate 51 and a second mounting plate 52, which are disposed opposite to each other on the mounting frame 1 along a second direction Y. The second direction Y is perpendicular to the first direction X. The first mounting plate 51 has a first protruding plate 511 and a second protruding plate 512 protruding towards the second mounting plate 52, which are spaced apart along the first direction X to form a first clamping space 104. The second mounting plate 52 has a third protruding plate 521 and a fourth protruding plate 522 protruding towards the first mounting plate 51, which are spaced apart along a direction perpendicular to the mounting frame 1 to form a second clamping space 105. One end of the light-transmitting plate 3 is clamped to the first clamping space 104, and the other end is clamped to the second clamping space 105. The first mounting plate 51 and the second mounting plate 52 are provided, and the protruding plates on the first mounting plate 51 and the second mounting plate 52 are provided to form the first clamping space 104 and the second clamping space 105. This provides a more stable installation space for the light-transmitting panel 3, and this installation method allows the light-transmitting panel 3 to be installed and removed in a pull-out manner, improving the convenience of installing and removing the light-transmitting panel 3.

[0031] In some embodiments, please refer to Figure 3 and Figure 5 The drying device 10 also includes a baffle 6, which is disposed on the mounting frame 1. The baffle 6 faces the light-transmitting plate 3 and is used to limit the displacement of the light-transmitting plate 3 along the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. The baffle 6, disposed on the mounting frame 1, limits the displacement of the light-transmitting plate 3 in the third direction Z, thereby improving the stability of the light-transmitting plate 3.

[0032] In some embodiments, please refer to Figure 4 The baffle 6 is provided with a first stop plate 61 and a second stop plate 62. The first stop plate 61 extends toward the light-transmitting plate 3. The second stop plate 62 includes a first part 621 and a second part 622, which are connected. The first part 621 and the first stop plate 61 are arranged parallel to each other and extend toward the light-transmitting plate 3. The second part 622 is inclined relative to the first part 621. A first stopping space 102 is formed between the first stop plate 61 and the second stop plate 62, which is used to limit the displacement of the light-transmitting plate 3. By providing the first stop plate 61 and the second stop plate 62 to form the first stopping space 102, the displacement of the light-transmitting plate 3 in the third direction Z can be more effectively limited.

[0033] In some embodiments, please refer to Figure 7The mounting bracket 1 is provided with a third stop plate 13 and a fourth stop plate 14. Along the third direction Z, the third stop plate 13 is positioned opposite the first stop plate 61, and the fourth stop plate 14 is positioned opposite the second stop plate 62. The third stop plate 13 extends towards the light-transmitting plate 3. The fourth stop plate 14 includes a third part 141 and a fourth part 142, which are connected. The third part 141 and the third stop plate 13 are parallel and extend towards the light-transmitting plate 3. The fourth part 142 is inclined relative to the third part 141. A second stop space 103 is formed between the third stop plate 13 and the fourth stop plate 14. Along the third direction Z, one end of the light-transmitting plate 3 is located in the first stop space 102, and the other end of the light-transmitting plate 3 is located in the second stop space 103. The mounting bracket 1 is equipped with a third stop plate 13 and a fourth stop plate 14 to form a second stop space 103, which can cooperate with the first stop space 102 to more effectively restrict the displacement of the light-transmitting plate 3 in the third direction Z, reduce the reduction of the drying effect of the drying lamp tube 2 caused by the instability of the light-transmitting plate 3 during the drying operation, and improve the drying efficiency.

[0034] In some embodiments, please refer to Figure 6 and Figure 7 Multiple ventilation holes 81 are provided on the first stop plate 61, the second stop plate 62, the third stop plate 13, and the fourth stop plate 14. The multiple ventilation holes 81 on the first stop plate 61, the second stop plate 62, the third stop plate 13, and the fourth stop plate 14 can more effectively carry the heat from the fan 4 to the drying area 101, improving drying efficiency. They also provide more effective blowing force, allowing the paper to better adhere to the conveyor platform and reducing the occurrence of edge curling and paper jams.

[0035] Secondly, this application proposes a printing apparatus, please refer to... Figure 7 The device includes a drying apparatus 10 as described in any embodiment of the first aspect and a paper feeding device 20, the paper feeding device 20 being disposed in the drying zone 101. The drying apparatus 10, in conjunction with the paper feeding device 20, can improve the efficiency of the drying operation.

[0036] In some embodiments, please refer to Figure 1 and Figure 8 The drying device 10 also includes an adjustment assembly. The adjustment assembly includes a first cylinder 71 and a second cylinder 72. Along the second direction Y, the first cylinder 71 and the second cylinder 72 are respectively disposed on both sides of the mounting frame 1. Along the third direction Z, one end of the mounting frame 1 is hinged to the paper feeding device 20, and the other end is connected to the first cylinder 71 and the second cylinder 72. By setting up the adjustment assembly and using the cylinders to adjust the angle of components such as the drying lamp tube 2, the drying efficiency can be improved. Furthermore, when drying is not required, the cylinders can be used to support the drying components, giving the paper feeding device 20 more operating space.

[0037] In some embodiments, please refer to Figure 1 and Figure 8 The adjustment assembly also includes a first gas spring 73 and a second gas spring 74. Along the second direction Y, the first gas spring 73 and the second gas spring 74 are disposed on both sides of the mounting bracket 1 and connected to the mounting bracket 1. The addition of the first gas spring 73 and the second gas spring 74 to the adjustment assembly assists the pushing action of the first cylinder 71 and the second cylinder 72, resulting in smoother angle adjustment of the drying component and reducing the possibility of damage to parts due to angle adjustment.

[0038] In this application, the drying lamp 2 generates high temperatures (up to 800℃~2000℃) when energized, transferring energy to the paper to be dried through thermal radiation. The light-transmitting characteristics of the light-transmitting plate 3 do not affect the energy transfer of the drying lamp 2, and the light-transmitting plate 3 isolates the drying lamp 2 and the paper, thereby reducing the possibility of lamp damage or fire caused by the paper coming into contact with the drying lamp 2 due to edge curling or other factors. The fan 4 blows air, and the airflow carries some heat to the drying area 101, which not only improves the drying efficiency, but also makes the paper adhere more closely to the paper feeding platform, reducing the occurrence of paper curling.
