[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] like Figure 1 and 2 As shown, some embodiments of the utility model provide a heating device, which is mainly used for heating and drying the coating 1000, so as to improve the heating efficiency of the coating 1000, improve the uniformity of heating the coating 1000, and improve the drying speed, drying efficiency and drying uniformity of the coating on the coating 1000.

[0043] The heating device includes a housing 100 , a rotating roller 200 and a heating element 300 .

[0044] It should be noted that the box 100 has a first direction, a second direction and a third direction which are perpendicular to each other. Specifically, the first direction refers to the length direction of the box 100 , the second direction refers to the height direction, and the third direction refers to the width direction of the box 100 .

[0045] The box body 100 defines a receiving cavity 110 having a ventilation hole 130 . It should be noted that, along the second direction, a ventilation hole 130 is provided on one side of the box body 100 .

[0046] Along the first direction, a first connecting hole 120 is provided on one side of the box body 100, and a second connecting hole 140 is provided on the other side of the box body 100. The first connecting hole 120 and the second connecting hole 140 are respectively connected to the accommodating cavity 110, so that one end of the coating 1000 can enter the accommodating cavity 110 through the first connecting hole 120 and extend out from the second connecting hole 140.

[0047] In this embodiment, the heating device includes a plurality of rotating rollers 200 , which are arranged in the accommodating cavity 110 at intervals and staggered along the first direction, and each rotating roller 200 is connected to the inner wall of the box body 100 .

[0048] It should be noted that the multiple rotating rollers 200 described here are staggered and spaced apart along the first direction in the accommodating cavity 110, which means that the multiple rotating rollers 200 are divided into at least two columns along the first direction, there is a gap between each column of rotating rollers 200 along the second direction, and two adjacent columns of rotating rollers 200 are staggered in the second direction.

[0049] Furthermore, the axis direction of each rotating roller 200 is parallel to the third direction.

[0050] It can be understood that by staggeredly arranging multiple rotating rollers 200 in the accommodating chamber 110, when the coating 1000 enters the accommodating chamber 110 through the first connecting hole 120, it can alternately pass through each rotating roller 200 in sequence along the first direction from the end close to the first connecting hole 120 to the end close to the second connecting hole 140, so that the coating 1000 forms a wavy structure in the accommodating chamber 110. This not only avoids overlapping of the coating 1000, but also improves the space utilization rate in the accommodating chamber 110.

[0051] The number of the rotating rollers 200 may be two or more than two, and may be set according to actual conditions.

[0052] The plurality of heating elements 300 are arranged in the accommodating cavity 110 at intervals. Specifically, the plurality of heating elements 300 are arranged along the first direction. It should be noted that the plurality of heating elements 300 are arranged in the accommodating cavity 110 at intervals means that the plurality of heating elements 300 are arranged at intervals along the first direction, and two adjacent heating elements 300 are arranged in an offset manner in the first direction.

[0053] Specifically, along the first direction, the heating elements 300 are respectively disposed on two opposite sides of the rotating roller 200 , and a gap is provided between the heating elements 300 and the rotating roller 200 .

[0054] It should be noted that by arranging multiple heating elements 300 at intervals to form a clearance space between two adjacent heating elements 300, when the coating 1000 passes through the surface of one of the rotating rollers 200, it can pass through the clearance space to contact the other rotating roller 200, thereby ensuring that the coating 1000 forms a wavy structure in the accommodating chamber 110, and the two opposite sides of the coating 1000 can be heated simultaneously by the heating elements 300, which not only improves the heating efficiency of the coating 1000, but also improves the uniformity of heating the coating 1000, thereby ensuring the heating quality and drying quality of the coating 1000.

[0055] It should be noted that the heating element 300 can be any one of a heating net, a heating wire, and a heating plate.

[0056] In this embodiment, the heating element 300 is taken as a heating plate as an example for detailed description as follows.

[0057] like Figure 2 As shown, in some embodiments of the present invention, the plurality of rotating rollers 200 include a plurality of first rotating rollers 210 and a plurality of second rotating rollers 220 .

[0058] The number of the first rotating rollers 210 and the number of the second rotating rollers 220 can be two or more than two arbitrary numerical values, and can be specifically set according to actual conditions.

[0059] In addition, a plurality of first rotating rollers 210 are arranged at intervals along the first direction, and a plurality of second rotating rollers 220 are arranged at intervals along the first direction. Along the first direction, the interval between two adjacent first rotating rollers 210 is equal to the interval between two adjacent second rotating rollers 220.

[0060] Furthermore, the first rotating roller 210 and the second rotating roller 220 are staggered along the second direction to form a zigzag rotating roller 200 structure in the accommodating cavity 110 .

[0061] like Figure 2 As shown, in some embodiments of the present invention, the heating assembly includes a first heating element 310 and a second heating element 320 .

[0062] Along the first direction, the first heating elements 310 are respectively provided on two opposite sides of the inner wall of the box body 100. Specifically, one of the first heating elements 310 is arranged on a side of the box body 100 close to the first connecting hole 120, and the other first heating element 310 is arranged on a side of the box body 100 close to the second connecting hole 140.

[0063] Along the second direction, each of the first rotating rollers 210 is provided with a second heating element 320 on the side facing the second rotating roller 220, and each of the second rotating rollers 220 is provided with a second heating element 320 on the side facing the first rotating roller 210, so as to form a clearance space between two adjacent second heating elements 320, so that the coating 1000 can pass through the clearance space after passing through the surface of the first rotating roller 210 and pass through the surface of the second rotating roller 220, thereby ensuring that both opposite sides of the coating 1000 can be heated by the first heating element 310 or the second heating element 320, so as to improve the heating efficiency and heating uniformity of the coating 1000, thereby ensuring the drying speed and drying quality of the coating 1000.

[0064] It should be noted that there is a gap between the first rotating roller 210 and the second rotating roller 220 and the second heating element 320 respectively to prevent the coating 1000 from contacting the second heating element 320 when passing through the first rotating roller 210 and the second rotating roller 220 respectively, thereby ensuring the stability and safety of the coating 1000 being heated and dried in the heating device.

[0065] like Figure 2As shown, in this embodiment, a first inclined surface is provided on the side of the first heating element 310 facing the second heating element 320, so that when the coating 1000 passes through the first connection hole 120 and the surface of the rotating roller 200, the first inclined surface can be directly opposite to the side of the coating 1000 close to the first heating element 310, so as to further improve the heating quality and heating efficiency of the first heating element 310 on the coating 1000 entering the accommodating chamber 110. Further, in this embodiment, the first inclined surface is parallel to the side of the coating 1000 facing the first heating element 310, so as to improve the uniformity of the first heating element 310 heating the coating 1000, thereby improving the uniformity of drying the coating 1000.

[0066] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the rotating roller 200 includes a rotating rod 230 , a first substrate layer 240 , a heating layer 250 and a second substrate layer 260 .

[0067] The first substrate layer 240 is sleeved on the rotating rod 230 , the heating layer 250 is sleeved on the first substrate layer 240 , and the second substrate layer 260 is sleeved on the heating layer 250 , so that the second substrate layer 260 is heated by the heating layer 250 to increase the surface temperature of the second substrate layer 260 .

[0068] It can be understood that the coating 1000 entering the accommodating cavity 110 can contact the surface of the second substrate layer 260 in the rotating roller 200, and the temperature of the surface of the second substrate layer 260 can be increased through the heating layer 250, so that the heat is transferred to the side of the coating 1000 that is attached to the second substrate layer 260 through the second substrate layer 260, so as to achieve the purpose of heating the coating 1000, so as to further improve the heating efficiency and drying efficiency of the coating 1000.

[0069] In addition, a plurality of air holes 261 are provided on the surface of the second substrate layer 260, and the plurality of air holes 261 are arranged in a circular array on the surface of the second substrate layer 260 to improve the uniformity of the hot air generated by the heating layer 250 being discharged from the air holes 261, thereby achieving uniform heating of the coating 1000 on the bonding rotating roller 200, so as to further improve the heating and drying efficiency of the coating 1000.

[0070] like Figure 2 As shown, in some embodiments of the present invention, a one-way valve 900 is further provided in the ventilation hole 130, and the one-way valve 900 is connected to the hole wall of the ventilation hole 130. The one-way valve 900 is a directional control valve that allows airflow to flow in only one direction but not in the reverse direction.

[0071] Specifically, the air inlet end of the one-way valve 900 is communicated with the accommodating chamber 110, that is, the air inlet end of the one-way valve 900 faces the accommodating chamber 110, and the air outlet end of the one-way valve 900 is communicated with the accommodating chamber 110 through the air inlet end. It can be understood that the gas in the accommodating chamber 110 can enter the one-way valve 900 through the air inlet end and be discharged from the air outlet end of the one-way valve 900, so that the gas in the accommodating chamber 110 is discharged to the outside of the box body 100 through the one-way valve 900.

[0072] By setting a one-way valve 900 in the ventilation hole 130, not only can the gas or steam in the accommodating chamber 110 be discharged through the one-way valve 900, but also dust, liquid, gas or other impurities outside the box body 100 can be prevented from entering the accommodating chamber 110 through the ventilation hole 130.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, a dustproof net 400 is provided in the ventilation hole 130, and the edge of the dustproof net 400 is connected to the hole wall of the ventilation hole 130, so as to filter dust through the dustproof net 400, thereby preventing dust outside the box 100 from entering the one-way valve 900, thereby providing protection for the one-way valve 900 through the dustproof net 400.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, a protective pad 500 is respectively provided in the first connecting hole 120 and the second connecting hole 140, so that when the coating 1000 passes through the first connecting hole 120 and the second connecting hole 140, one side of the coating 1000 can overlap the surface of the protective pad 500, so as to provide a buffering and protective effect to the coating 1000 through the protective pad 500, reduce the friction between the coating 1000 and the box body 100, and thus ensure the integrity of the coating 1000.

[0075] It should be noted that, in this embodiment, the protection pad 500 is a sponge pad.

[0076] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the heating device includes a fan structure 600 , which is disposed in the accommodating cavity 110 , and the fan structure 600 is connected to the inner wall of the box body 100 .

[0077] It can be understood that when the fan structure 600 is running, it can drive the gas flow in the accommodating cavity 110, thereby forming a circulating airflow in the accommodating cavity 110, so as to improve the evaporation efficiency of the moisture on the surface of the coating 1000 through the circulation of air, and further improve the drying speed of the coating 1000.

[0078] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the fan structure 600 includes a mounting block 610 , a driving motor 620 and a fan 630 .

[0079] The mounting block 610 is disposed on one side of the box body 100 and is close to the ventilation hole 130 . The connection between the mounting block 610 and the box body 100 includes any one of bolt connection, bonding, and clamping.

[0080] The driving motor 620 is disposed on a side of the mounting block 610 facing the rotating roller 200 , and the output end of the driving motor 620 faces the rotating roller 200 . The fan 630 is connected to the output end of the driving motor 620 to drive the fan 630 to rotate.

[0081] It is understandable that the rotation speed of the fan 630 is adjusted by driving the motor 620 to adjust the circulation speed of the gas in the receiving chamber 110 , thereby adjusting the drying efficiency of the coating 1000 in the receiving chamber 110 .

[0082] like Figure 1 As shown, in some embodiments of the present invention, the box body 100 is provided with an opening on one side along the third direction, and the box body 100 is provided with a door 150 on the side facing the opening, and the door 150 is rotatably connected to the box body 100 and covers the opening.

[0083] The box door 150 is embedded with an observation window 151 , so that the user can observe the drying condition of the coating 1000 in the accommodating chamber 110 through the observation window 151 .

[0084] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, along the second direction, a support structure is provided at the bottom of the box 100, and the support structure includes a support plate 700 and a support column 800. A support column 800 is provided at the top corner of the support plate 700 to provide support for the box 100 through the support structure, thereby improving the stability of the box 100 on the support platform.

[0085] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0086] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0087] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
