The plurality of partition bottom plates are spaced apart, and the air outlet gap is formed between adjacent partition bottom plates.

[0009] In one optional embodiment, one end of the partition base plate is provided with a first inclined portion that is radially deflected at a first angle, and the other end of the partition base plate is provided with a second inclined portion that is radially deflected at a second angle.

[0014] According to another aspect of this application, a drying system is provided, including a drying chamber as described above.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment includes a mounting bracket, a drying roller, a wind box assembly, and a heating element. The mounting bracket has a receiving cavity, the drying roller is disposed within the receiving cavity and rotatably connected to the mounting bracket, the wind box assembly is disposed within the receiving cavity and connected to the mounting bracket, and the wind box assembly and the drying roller are radially spaced apart. The wind box assembly has multiple air outlet gaps on the side near the drying roller, and these gaps are inclined at an angle to the radial direction of the drying roller. The heating element is connected to the wind box assembly and is used to heat the airflow. The heated airflow flows into the wind box assembly and exits through the multiple air outlet gaps on the wind box assembly. Because the multiple air outlet gaps are inclined at an angle to the radial direction of the drying roller… In this configuration, the heated airflow flows at an inclined angle from multiple air outlet gaps to the outer wall of the drying roller. Since the paper is located on the outer wall of the drying roller, the heated airflow impacts the paper surface at an inclined angle. As the airflow is blown out at an inclined angle, the impact force is decomposed into a tangential component parallel to the paper surface and a smaller vertical component. The smaller vertical component allows the paper to adhere stably to the outer surface of the drying roller. At the same time, the wind speed gradient of the tangential airflow on the paper surface is relatively gentle, making it less likely for the wind speed to be high in the central area and low in the surrounding area. This reduces uneven temperature distribution on the paper surface and minimizes curling, wrinkling, and deformation of the paper surface. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Furthermore, 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.

[0021] Please see Figure 1The drying oven 1000 includes a mounting bracket 10, a drying roller 20, an air box assembly 30, and a heating element 40. The drying roller 20 is rotatably connected to the mounting bracket 10, the air box assembly 30 is disposed on the mounting bracket 10, and the air box assembly 30 and the drying roller 20 are radially spaced upwards. The air box assembly 30 is in communication with the heating element 40, and the heated airflow in the heating element 40 flows through the air box assembly 30 and at least partially flows to the outer wall of the drying roller 20.

[0022] Regarding the aforementioned mounting bracket 10 and drying roller 20, as Figure 1 and Figure 2 As shown, the mounting bracket 10 is provided with a receiving cavity 10a, and the drying roller 20 is disposed within the receiving cavity 10a. The drying roller 20 is rotatably connected to the mounting bracket 10, and the paper to be dried is wound around at least a portion of the drying roller 20. The drying roller 20 can be used to guide the paper in a circular, surrounding manner to a preset position, wherein the paper is located on the outer wall of the drying roller 20, and the paper moves, driving the drying roller 20 to rotate through friction. Optionally, the mounting bracket 10 includes a first fixing plate 101 and a second fixing plate 102, the first fixing plate 101 and the second fixing plate 102 are connected to each other and spaced apart from each other, and the receiving cavity 10a is formed between the first fixing plate 101 and the second fixing plate 102. One end of the drying roller 20 is rotatably connected to the first fixing plate 101, and the other end of the drying roller 20 is rotatably connected to the second fixing plate 102.

[0023] For the aforementioned bellows assembly 30 and heating assembly 40, such as Figure 1 and Figure 2As shown, the bellows assembly 30 is disposed in the receiving cavity 10a and connected to the mounting bracket 10. The bellows assembly 30 and the drying roller 20 are arranged radially upwards at intervals. The bellows assembly 30 has multiple air outlet gaps 30a on the side near the drying roller 20. The heating element 40 is connected to the bellows assembly 30 and is used to heat the airflow. The heated airflow flows into the bellows assembly 30 and flows at least partially to the drying roller 20 through the multiple air outlet gaps 30a. In some embodiments, the plurality of air outlet gaps 30a are arranged at an inclined angle to the radial direction of the drying roller 20. Thus, the heated airflow flows at an inclined angle from the plurality of air outlet gaps 30a to the outer wall of the drying roller 20. Since the paper is located on the outer wall of the drying roller 20, the heated airflow impacts the paper surface at an inclined angle. Due to the inclined airflow, the impact force is decomposed into a tangential component parallel to the paper surface and a smaller vertical component. The smaller vertical component allows the paper to stably adhere to the outer surface of the drying roller. Simultaneously, the wind speed gradient of the tangentially flowing airflow on the paper surface is relatively gentle, reducing the likelihood of high wind speed in the central area and low wind speed in the surrounding area. This reduces uneven temperature distribution on the paper surface, minimizing curling, wrinkling, and deformation. It is understood that this application does not specifically limit whether the drying roller 20 feeds paper clockwise or counterclockwise; the rotation direction of the drying roller 20 and the airflow direction of the air outlet gaps 30a can be the same or opposite. Optionally, the rotation direction of the drying roller 20 is opposite to the airflow direction of the air outlet gap 30a.

[0024] In some embodiments, please refer to the following: Figure 3 and Figure 4 The air box assembly 30 includes a fan-shaped air box 301. The fan-shaped air box 301 is provided with a receiving space 301a and an air outlet 301b communicating with the receiving space 301a. The receiving space 301a is connected to the heating element 40. The air outlet 301b is at least partially opposite to a plurality of air outlet gaps 30a and faces the drying roller 20. The airflow heated by the heating element 40 flows into the receiving space 301a and flows out through the plurality of air outlet gaps 30a. At least a portion of the airflow flowing out from the air outlet gaps 30a flows from the air outlet 301b to the drying roller 20 to dry the paper located on the drying roller 20. It is understood that there can be multiple fan-shaped air boxes 301, which are arranged around the drying roller 20, with adjacent fan-shaped air boxes 301 spaced apart. The number of fan-shaped air boxes 301 can be two or more.

[0025] In some embodiments, when viewed axially upwards, the air outlet 301b is arc-shaped. Since the outer wall of the drying roller 20 is arc-shaped, the arc-shaped arrangement of the air outlet 301b can increase the contact area between the hot airflow flowing out of the air outlet 301b and the outer wall of the drying roller 20, thereby improving the drying efficiency of the paper on the drying roller 20.

[0026] In some embodiments, the fan-shaped air box 301 is provided with a first air cavity 301aa and a second air cavity 301ab. The first air cavity 301aa is connected to the second air cavity 301ab through multiple air outlet gaps 30a. The fan-shaped air box 301 is also provided with a first air outlet 301c and a second air outlet 301d. The first air outlet 301c is connected to the first air cavity 301aa, and the second air outlet 301d is connected to the second air cavity 301ab. The first air cavity 301aa is connected to the heating element 40. It should be noted that the second air outlet 301d is usually connected to an external exhaust component to remove humid and hot gas and to create a slight negative pressure in the containing space 301a to prevent humid and hot gas from leaking out, so as not to affect the ambient temperature around the printing carriage and to prevent the ink from drying on the print head of the printing carriage. The hot airflow heated by the heating element 40 flows into the first air chamber 301aa and flows out through multiple air outlet gaps 30a. The hot airflow flows from the air outlet 301b to the drying roller 20 to dry the paper on the drying roller 20. After contacting the paper surface, the hot airflow flows along the outer circle of the drying roller 20 to the second air chamber 301ab and flows to the exhaust component through the second air outlet 301d.

[0027] In some embodiments, please refer to the following: Figure 5 The fan-shaped air box 301 also includes a first partition plate 3011, a second partition plate 3012, a partition side plate 3013, and a plurality of partition bottom plates 3014. The first partition plate 3011, the second partition plate 3012, the partition side plate 3013, and the plurality of partition bottom plates 3014 are all disposed within the accommodating space 301a. The first partition plate 3011 and the second partition plate 3012 are spaced apart along the axial direction. The two ends of the plurality of partition bottom plates 3014 are respectively connected to the first partition plate 3011 and the second partition plate 3012 along the axial direction. The plurality of partition bottom plates 3014 are spaced apart from the inner wall of the fan-shaped air box 301 along the radial direction. The first partition plate 3011, the second partition plate 3012, the partition side plate 3013, and the plurality of partition bottom plates 3014 enclose a first air cavity 301aa. The plurality of partition bottom plates 3014 are spaced apart, and an air outlet gap 30a is formed between adjacent partition bottom plates 3014. The partition side plate 3013 is located between the first air cavity 301aa and the second air cavity 301ab. It can be understood that in other embodiments, the first partition plate 3011 and the second partition plate 3012 can be omitted, thereby, the two ends of the plurality of partition bottom plates 3014 are directly connected to the two inner walls of the fan-shaped air box 301 along the axial direction.

[0028] In some embodiments, please refer to the following: Figure 6 One end of the partition base plate 3014 is provided with a first inclined portion 30141 that is radially deflected by a first angle, and the other end of the partition base plate 3014 is provided with a second inclined portion 30142 that is radially deflected by a second angle. The first inclined portion 30141 and the second inclined portion 30142 on a single partition base plate 3014 are arranged opposite to each other. The second inclined portion 30142 is also provided with a bent portion 30143. The first inclined portion 30141 of one partition base plate 3014 and the second inclined portion 30142 of another adjacent partition base plate 3014 are... The first inclined portion 30141 of one partition base plate 3014 and the bent portion 30143 of another adjacent partition base plate 3014 are arranged at an angle and spaced apart. An air guide gap 30b is formed between the first inclined portion 30141 of one partition base plate 3014 and the second inclined portion 30142 of another adjacent partition base plate 3014, and an air outlet gap 30a is formed between the first inclined portion 30141 of one partition base plate 3014 and the bent portion 30143 of another adjacent partition base plate 3014. The air guide gap 30b guides the hot airflow flowing into the first air cavity 301aa, directing at least a portion of the hot airflow to the air outlet gap 30a, through which the hot airflow flows to the outer wall of the drying roller 20. It should be noted that the specific values ​​of the first and second angles are not specifically limited in this application; users can set them according to actual needs.

[0029] In some embodiments, please refer to the following: Figure 7 and Figure 8 The bellows assembly 30 also includes a rotating shaft 302, a first mounting base 303, and a second mounting base 304. The first mounting base 303 is detachably connected to one side of the fan-shaped bellows 301. One end of the second mounting base 304 is connected to the mounting bracket 10, and the other end of the second mounting base 304 abuts against the other side of the fan-shaped bellows 301. One end of the rotating shaft 302 is connected to the first mounting base 303, and the other end of the rotating shaft 302 is rotatably connected to the mounting bracket 10. One side of the fan-shaped bellows 301 can rotate relative to the mounting bracket 10 at a preset angle. This configuration allows the other side of the fan-shaped bellows 301 to be lifted, which facilitates the passage of paper on the drying roller 20 and also facilitates the cleaning of impurities in the gap between the fan-shaped bellows 301 and the drying roller 20. It should be noted that in order to enable one side of the fan-shaped bellows 301 to rotate relative to the mounting bracket 10, the rotating shaft 302 and the first mounting base 303 form a rotating assembly. There are two rotating assemblies, which are respectively arranged at both ends of the fan-shaped bellows 301 along the axial direction.

[0030] In some embodiments, please refer to the following: Figure 9 and Figure 10 A connecting hole 301e is provided on one side of the fan-shaped air box 301. A connector (not shown) and a connecting groove 303a are provided on the first mounting base 303. The connecting groove 303a extends radially upward, and at least a portion of the connecting groove 303a is positioned opposite to the connecting hole 301e. The connector passes through the connecting groove 303a and is connected to the connecting hole 301e. The first mounting base 303 is connected to the connecting hole 301e through the connector passing through the connecting groove 303a, thereby achieving the connection between the first mounting base 303 and the fan-shaped air box 301. It should be noted that since the connecting groove 303a extends radially upward, the user can adjust the position of the connector within the connecting groove 303a to correspondingly move the position of the fan-shaped air box 301 radially upward. This allows adjustment of the radially upward spacing between the fan-shaped air box 301 and the drying roller 20. Optionally, the connector can be a screw, rivet, or other connecting component.

[0031] In some embodiments, there are multiple connecting holes 301e, which are arranged radially upwards at intervals. The connecting groove 303a can be moved radially upwards to a preset position to connect one of the connecting holes 301e.

[0032] In some embodiments, the bellows assembly 30 further includes a connecting pipe 305 and a temperature sensor 306. One end of the connecting pipe 305 is connected to a first air outlet 301c, and the other end of the connecting pipe 305 is connected to a heating element 40. A portion of the temperature sensor 306 is located at the first air outlet 301c. Hot airflow within the heating element 40 can be transmitted through the connecting pipe 305 to the first air outlet 301c and flows into the first air cavity 301aa through the first air outlet 301c. The temperature sensor 306 can detect the temperature of the airflow entering the first air cavity 301aa.

[0033] In some embodiments, such as Figure 7 and Figure 11 As shown, the heating component 40 includes a heating chamber 401 and a heating tube 402. The heating chamber 401 is provided with a mounting cavity 401a and a first opening 401b and a second opening 401c communicating with the mounting cavity 401a. The heating tube 402 is disposed in the mounting cavity 401a, and the first opening 401b communicates with a first air outlet 301c. External airflow can enter the heating chamber 401 through the second opening 401c. The heating tube 402 can generate heat to heat the external airflow entering the heating chamber 401. The heated airflow flows through the first opening 401b into the first air outlet 301c, and then through the first air outlet 301c into the first air cavity 301aa.

[0034] In some embodiments, the heating element 40 includes a heavy-duty connector 403 that connects to the heating element 402. The heavy-duty connector 403 can be used to connect other external electrical devices.

[0035] In this embodiment, a mounting bracket 10, a drying roller 20, a bellows assembly 30, and a heating element 40 are provided. The mounting bracket 10 has a receiving cavity 10a, and the drying roller 20 is disposed within the receiving cavity 10a and rotatably connected to the mounting bracket 10. The bellows assembly 30 is disposed within the receiving cavity 10a and connected to the mounting bracket 10. The bellows assembly 30 and the drying roller 20 are radially spaced apart. Multiple air outlet gaps 30a are provided on the side of the bellows assembly 30 closest to the drying roller 20, and these gaps are inclined at an angle to the radial direction of the drying roller 20. The heating element 40 is connected to the bellows assembly 30 and is used to heat the airflow. The heated airflow flows into the bellows assembly 30 and exits through the multiple air outlet gaps 30a on the bellows assembly 30. Multiple air outlet gaps 30a are set at an inclined angle to the radial direction of the drying roller 20. As a result, the heated airflow flows from the multiple air outlet gaps 30a at an inclined angle to the outer wall of the drying roller 20. Since the paper is located on the outer wall of the drying roller 20, the heated airflow impacts the paper surface at an inclined angle. Due to the inclined airflow, the impact force is decomposed into a tangential component parallel to the paper surface and a smaller vertical component. The smaller vertical component allows the paper to be stably attached to the outer surface of the drying roller. At the same time, the wind speed gradient of the tangential airflow on the paper surface is relatively gentle, and it is not easy for the wind speed to be high in the central area and low in the surrounding area. This can reduce the uneven temperature distribution on the paper surface and reduce the curling, wrinkling and deformation of the paper surface.

[0036] This application also provides an embodiment of a drying system, which includes a drying chamber 1000 as described above. The function and structure of the drying chamber 1000 can be found in the above embodiments, and will not be repeated here.

[0037] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
