Description

Technical Field

[0001] This utility model relates to the technical field of water transfer printing manufacturing equipment, and in particular to a quick-release structure for a sealing strip and a water transfer printing oven. Background Technology

[0002] Water transfer printing paper is a product designed to transfer printed images. It uses special paper as its base material, which is made by forming different fibers into paper with special functions using a papermaking machine.

[0003] In the existing water transfer printing paper manufacturing process, drying operations are indispensable for activating the substrate, pattern, product, or UV protective layer, and drying operations usually require the use of an oven.

[0004] like Figure 1 and Figure 5 As shown, a typical tunnel-type drying oven 1 mainly includes an upper drying oven 11 and a lower drying oven 12. The upper drying oven 11 can rotate and cover the lower drying oven 12 to form a drying conveying chamber between them. Hot air is introduced into the drying conveying chamber by a heating component for drying operations. At the same time, a strip-shaped high-temperature resistant sealing strip 3 is provided along the edge of the lower drying oven 12 on the human-machine operation side. The high-temperature resistant sealing strip 3 is pressed and fixed by one end of a pressure plate 2, and the other end of the pressure plate 2 is fixed to the lower drying oven 12 body by multiple linearly distributed fastening screws 21. In this way, when the upper drying oven 11 rotates and covers the lower drying oven 12, the upper drying oven 11 abuts against the lower high-temperature resistant sealing strip 3, thereby sealing and insulating the internal drying conveying chamber and preventing heat loss.

[0005] However, the high-temperature resistant sealing strip 3 mentioned above is prone to wear or breakage during long-term use, and the disassembly of multiple fastening screws 21 is very cumbersome, resulting in poor ease of disassembly and replacement of the high-temperature resistant sealing strip 3. Utility Model Content

[0010] The quick-release pressure plate includes an inclined insertion part and a fixing part; the fixing part and the positioning protrusion are stacked in a staggered manner on the end face of the lower oven along the human-machine operation side, the inclined insertion part is engaged in the inclined slot, so that the fixing part abuts and presses against the positioning protrusion, wherein the back of the inclined insertion part is provided with multiple disassembly pry holes, and the multiple disassembly pry holes are connected to the multiple clearance slots one by one.

[0011] In one embodiment, the flexible sealing strip is made of glass fiber cloth or ceramic fiber cloth.

[0012] In one embodiment, the resilient sealing portion is cylindrical, and the resilient sealing portion contains a resilient cylindrical component.

[0013] In one embodiment, the elastic cylindrical member is an elastic metal mesh component, and the elastic cylindrical member is hollow.

[0014] In one embodiment, the positioning protrusion is flat.

[0015] In one embodiment, the inclined insertion portion protrudes from a plurality of snap-fit ​​protrusions;

[0016] The lower oven is also provided with multiple slots along the human-machine operation side. The multiple slots are set on the inner wall of the inclined slot opening, and the multiple locking protrusions are locked in one-to-one with the multiple slots.

[0017] In one embodiment, the lower end face of the fixing part is provided with a plurality of conical barbs, which are used to be inserted into the positioning protrusion.

[0018] In one embodiment, the plurality of the conical barbs are all inclined, and the inclination angle of each conical barb is the same as the inclination angle of the inclined slot opening.

[0019] In one embodiment, the quick-release pressure plate is a bent, integrally formed structure.

[0020] A water transfer printing oven includes an upper oven, a lower oven, and a quick-release sealing strip structure as described in any of the above embodiments; the upper oven and the lower oven are rotatably connected at one end away from the human-machine operation side, and the lower oven has an oblique slot opening and a plurality of clearance slots along the human-machine operation side, and the plurality of clearance slots are all connected to the oblique slot opening.

[0021] Compared with the prior art, the present invention has at least the following advantages:

[0022] When installing the flexible sealing strip, the slanted insert of the quick-release pressure plate is engaged with the slanted slot, and the fixing part of the quick-release pressure plate abuts and presses against the positioning protrusion, thus quickly completing the installation and fixing of the flexible sealing strip. This way, when the upper oven rotating cover is placed on the lower oven, the elastic sealing part deforms under pressure and seals between the upper and lower ovens. Conversely, when disassembling the flexible sealing strip, an external tool is used to apply leverage through the clearance groove to the disassembly pry hole, easily prying the slanted insert out along the slanted slot, thus quickly completing the disassembly and replacement of the flexible sealing strip. This utility model's quick-release sealing strip structure eliminates the need for multiple fastening screws to fix the pressure plate, improving the convenience of installing and removing the flexible sealing strip.

[0033] This disclosure provides a quick-release structure for a sealing strip, including a flexible sealing strip and a quick-release pressure plate. The flexible sealing strip includes a positioning protrusion and an elastic sealing portion. The elastic sealing portion is used to seal between an upper oven and a lower oven after being deformed under pressure. The lower oven has an inclined slot and multiple clearance slots on its end face along the human-machine operation side, and the multiple clearance slots are all connected to the inclined slot. The quick-release pressure plate includes an inclined insertion portion and a fixing portion. The fixing portion and the positioning protrusion are stacked in a staggered manner on the end face of the lower oven along the human-machine operation side. The inclined insertion portion is engaged in the inclined slot, so that the fixing portion abuts and presses against the positioning protrusion. The back of the inclined insertion portion has multiple disassembly pry holes, and the multiple disassembly pry holes are connected to the multiple clearance slots one by one.

[0034] Please see Figures 2 to 5 To better understand the quick-release structure 10 of the sealing strip in this application, the following further explanation of the quick-release structure 10 of the sealing strip is provided:

[0035] One embodiment of the quick-release sealing strip structure 10 includes a flexible sealing strip 100 and a quick-release pressure plate 200. The flexible sealing strip 100 includes a positioning protrusion 110 and an elastic sealing part 120. The elastic sealing part 120 is used to seal between the upper oven 11 and the lower oven 12 after being deformed under pressure. The lower oven 12 has a slanted slot 1201 and a plurality of clearance grooves 1202 on the end face along the human-machine operation side. The plurality of clearance grooves 1202 are all connected to the slanted slot 1201. The quick-release pressure plate 200 includes a slanted insertion part 210 and a fixing part 220. The fixing part 220 and the positioning protrusion 110 are stacked in a staggered manner on the end face of the lower oven 12 along the human-machine operation side. The slanted insertion part 210 is engaged in the slanted slot 1201, so that the fixing part 220 abuts and presses against the positioning protrusion 110. The back of the slanted insertion part 210 has a plurality of disassembly pry holes 2101, and the plurality of disassembly pry holes 2101 are connected to the plurality of clearance grooves 1202 one by one.

[0036] In this embodiment, when the flexible sealing strip 100 needs to be installed, the inclined insertion portion 210 of the quick-release pressure plate 200 is engaged into the inclined slot opening 1201, and the fixing portion 220 of the quick-release pressure plate 200 abuts and presses against the positioning protrusion 110, thereby quickly completing the installation and fixing of the flexible sealing strip 100. Thus, when the upper oven 11 rotates and covers the lower oven 12, the elastic sealing portion 120 is deformed under pressure and sealed between the upper oven 11 and the lower oven 12. Conversely, when the flexible sealing strip 100 needs to be disassembled, an external tool is used to apply leverage force to the disassembly pry hole 2101 through the clearance groove 1202, easily prying the inclined insertion portion 210 out along the inclined slot opening 1201, thereby quickly completing the disassembly and replacement of the flexible sealing strip 100. The quick-release structure 10 of this utility model eliminates the need for multiple fastening screws to fix the pressure plate, improving the convenience of installing and disassembling the flexible sealing strip 100.

[0037] It should be noted that the structural principle of the upper oven 11 being able to rotate and cover the lower oven 12 is existing technology and will not be elaborated here.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the flexible sealing strip 100 is made of fiberglass cloth or ceramic fiber cloth. In one embodiment, the elastic sealing portion 120 is cylindrical, and the elastic sealing portion 120 has an elastic cylindrical member 1210 built inside.

[0039] It is understandable that by using fiberglass cloth or ceramic fiber cloth to manufacture the flexible sealing strip 100, that is, by using fiberglass cloth or ceramic fiber cloth to wrap the outer peripheral wall of the elastic cylindrical part 1210, the elastic sealing part 120 has elastic deformation properties as well as fireproof and high temperature resistance properties. In this way, when the upper oven 11 rotates and covers the lower oven 12, the elastic cylindrical part 1210 inside the elastic sealing part 120 is compressed and deformed, so that the fiberglass cloth or ceramic fiber cloth on the outer peripheral wall of the elastic cylindrical part 1210 is sealed between the upper oven 11 and the lower oven 12, thereby achieving a sealing and heat preservation effect and preventing heat loss.

[0040] like Figure 3 and Figure 5 As shown, in one embodiment, the elastic cylindrical member 1210 is an elastic metal mesh component, and the elastic cylindrical member 1210 is hollow.

[0041] It is understood that the elastic cylindrical component 1210 is made of metal wire or metal strip wound into a cylindrical mesh structure, and the elastic cylindrical component 1210 is hollow, so that the elastic metal mesh component has elastic deformation properties, thereby providing elastic deformation properties for the elastic sealing part 120. This allows it to fit better between the upper oven 11 and the lower oven 12, and play a better sealing and heat preservation role.

[0042] like Figures 3 to 5 As shown, in one embodiment, the positioning protrusion 110 is flat. This allows the fixing part 220 to better abut and fit with the positioning protrusion 110, ensuring the fixing effect of the positioning protrusion 110.

[0043] like Figure 3 and Figure 5 As shown, in one embodiment, the inclined insertion part 210 is provided with a plurality of snap-fit ​​protrusions 2110; the lower oven 12 is also provided with a plurality of slots 1203 along the human-machine operation side, the plurality of slots 1203 are provided on the inner wall of the inclined slot opening 1201, and the plurality of snap-fit ​​protrusions 2110 are snapped into the plurality of slots 1203 one by one.

[0044] It can be understood that the angled insertion part 210 is snapped into the angled slot opening 1201. Specifically, multiple snap-fit ​​protrusions 2110 are snapped into multiple slots 1203 one by one, so that the angled insertion part 210 and the angled slot opening 1201 are snapped into connection, which improves the ease of disassembly and assembly of the quick-release pressure plate 200. It eliminates the need to use multiple fastening screws to fix the pressure plate during installation, and improves the ease of disassembly and assembly of the flexible sealing strip 100.

[0045] like Figure 3 and Figure 5As shown, in one embodiment, the lower end face of the fixing part 220 is provided with a plurality of conical barbs 2210, which are used to insert into the positioning protrusion 110. In this way, the stability of the positioning protrusion 110 is well ensured and the positioning protrusion 110 is prevented from loosening, that is, the structural stability of the flexible sealing strip 100 after it is fixedly installed is well ensured.

[0046] like Figure 3 and Figure 5 As shown, in one embodiment, the plurality of tapered barbs 2210 are all inclined, and the inclination angle of each tapered barb 2210 is the same as the inclination angle of the inclined slot opening 1201. Thus, when the inclined insertion part 210 is engaged in the inclined slot opening 1201, the tapered barbs 2210 are simultaneously inserted into the positioning protrusion 110. The tapered barbs 2210 provide resistance against dislodgement to the positioning protrusion 110, effectively ensuring the structural stability of the flexible sealing strip 100 after fixed installation.

[0047] Furthermore, since the flexible sealing strip 100 is made of glass fiber cloth or ceramic fiber cloth, even if the positioning protrusion 110 is made of glass fiber cloth or ceramic fiber cloth, the cone-shaped barb 2210 can penetrate the positioning protrusion 110 to prevent it from falling off.

[0048] like Figure 3 and Figure 5 As shown, in one embodiment, the quick-release pressure plate 200 is a bent, integrally formed structure. This ensures that the inclined insertion portion 210 and the fixing portion 220 are bent at a preset angle, while also ensuring that the quick-release pressure plate 200 has better structural strength.

[0049] Please see Figures 2 to 5 This application also provides a water transfer printing oven 1, including an upper oven 11, a lower oven 12, and the quick-release sealing strip structure 10 described in any of the above embodiments; the upper oven 11 and the lower oven 12 are rotatably connected at one end away from the human-machine operation side, and the lower oven 12 is provided with an oblique slot 1201 and a plurality of clearance slots 1202 along the human-machine operation side, and the plurality of clearance slots 1202 are all connected to the oblique slot 1201.

[0050] In this embodiment, the water transfer printing oven 1 employs the aforementioned quick-release sealing strip structure 10. When the flexible sealing strip 100 needs to be installed, the quick-release pressure plate 200's oblique insertion portion 210 is engaged with the oblique slot opening 1201, causing the fixing portion 220 of the quick-release pressure plate 200 to abut against and press against the positioning protrusion 110, thus quickly completing the installation and fixing of the flexible sealing strip 100. This way, when the upper oven 11 rotates and covers the lower oven 12, the elastic sealing portion 120 is deformed under pressure and sealed between the upper oven 11 and the lower oven 12. Conversely, when the flexible sealing strip 100 needs to be disassembled, an external tool is used to apply leverage force through the clearance groove 1202 to the disassembly pry hole 2101, easily prying the oblique insertion portion 210 out along the oblique slot opening 1201, thus quickly completing the disassembly and replacement of the flexible sealing strip 100. The water transfer printing oven 1 of this utility model does not require the installation method of fixing the pressure plate with multiple fastening screws, which makes the flexible sealing strip 100 easier to disassemble and replace.

[0051] It should be noted that when it is necessary to use external tools to apply leverage force to the disassembly pry hole 2101 through the clearance groove 1202, specific tools such as pry bars, pry sticks or common screwdrivers can be used to apply leverage force to the disassembly pry hole 2101, that is, using the oven 12 as the fulcrum to pry the inclined insertion part 210.

[0052] Compared with the prior art, the present invention has at least the following advantages:

[0053] When installing the flexible sealing strip, the slanted insert of the quick-release pressure plate is engaged with the slanted slot, and the fixing part of the quick-release pressure plate abuts and presses against the positioning protrusion, thus quickly completing the installation and fixing of the flexible sealing strip. This way, when the upper oven rotating cover is placed on the lower oven, the elastic sealing part deforms under pressure and seals between the upper and lower ovens. Conversely, when disassembling the flexible sealing strip, an external tool is used to apply leverage through the clearance groove to the disassembly pry hole, easily prying the slanted insert out along the slanted slot, thus quickly completing the disassembly and replacement of the flexible sealing strip. This utility model's quick-release sealing strip structure eliminates the need for multiple fastening screws to fix the pressure plate, improving the convenience of installing and removing the flexible sealing strip.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
