Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to an oven for a coating machine. Background Technology

[0002] Coating machines are typically used to apply functional coatings to rolls of substrate and to rewind the dried products.

[0003] In the prior art, a Chinese patent entitled "A Coating Machine Oven" (patent application number: CN202220828201.0) discloses a coating machine oven. After the heating and drying are completed, the heating device stops heating, but the residual heat of the heating device will still heat the substrate. At this time, the exhaust fan starts to work. The exhaust fan carries away the heat of the heating device through the exhaust pipe, which can quickly dissipate heat from the heating device and prevent the residual heat from affecting the quality of the substrate. However, the heating device is still inside the oven and dissipates heat only through the exhaust fan, so the efficiency is generally low.

[0004] Therefore, it is necessary to propose a new oven for coating machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oven for a coating machine to solve the problem that the heating device is still inside the oven and heat is dissipated only through an exhaust fan, resulting in general inefficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oven for a coating machine, comprising an operating box, wherein both ends of the operating box are rotatably connected to first guide columns, and a second guide column is rotatably disposed above the middle of the two first guide columns. Heating components are disposed on both sides of the second guide column, and each heating component includes a connecting plate and heating devices. Two heating devices are configured, and the heating devices are fixedly connected to the connecting plate. The connecting plate and the two heating devices are distributed in a U-shape, forming a heating channel between the two heating devices for the base fabric to pass through. An insulation box is fixedly connected to the outer wall of the operating box, and a through groove is provided on the side wall of the operating box for the heating components to pass through. The operating box is connected to the insulation box through the through groove, and an exhaust pipe is connected to the top of the operating box. An exhaust fan is installed inside the exhaust pipe.

[0007] Preferably, a sliding groove is provided through the top of the side wall of the control box, a sliding plate is slidably disposed inside the sliding groove, and the sliding plate is attached to the lower surface of the top of the control box, and a second round rod is fixedly connected to one end of the sliding plate outside the control box.

[0008] Preferably, the interior of the insulated box is provided with a connecting frame, the two ends of which are fixedly connected to two connecting plates respectively. A first round rod is fixedly connected to the connecting frame, and the insulated box has a round hole for the first round rod to pass through.

[0009] Preferably, a vertical plate is fixedly connected to the end of the second round rod away from the slide plate, and the end of the vertical plate away from the second round rod is fixedly connected to the first round rod. A first electric push rod is fixedly connected to the outer wall of the operation box, and the vertical plate is fixedly connected to the telescopic end of the first electric push rod.

[0010] Preferably, a closing component is provided at the through slot, and the closing component is located inside the insulation box. The closing component includes a baffle and a second electric push rod. The second electric push rod is fixedly connected to the outer wall of the operating box, and the baffle is fixedly connected to the telescopic end of the second electric push rod.

[0011] Preferably, the heating components are inclined and the two sets of heating components are distributed in an inverted V shape.

[0012] The technical advantages of this utility model are as follows: By setting up a heating component and an insulation box, the heating component is recycled from the through groove into the interior of the insulation box, so that the heating component is away from the substrate. At the same time, the exhaust fan is activated, and the exhaust fan carries away the residual heat through the exhaust pipe, preventing the residual heat from affecting the quality of the substrate. After the heating component is recycled into the interior of the insulation box, it can achieve the effect of heat preservation. In the next round of drying operation, it can be quickly heated to the set temperature, reducing energy consumption.

[0013] During the drying process, the slide plate closes the bottom of the exhaust pipe to prevent heat from escaping; while during the heat dissipation process, the slide plate slides outward from the inside of the groove, allowing the bottom of the exhaust pipe to open without affecting the operation of the exhaust fan.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, this utility model provides an oven for a coating machine, including an operating box 1. An insulated box 4 is fixedly connected to the outer wall of the operating box 1. First guide pillars 2 are rotatably connected to both ends inside the operating box 1. A second guide pillar 3 is rotatably positioned above the middle of the two first guide pillars 2. Heating components are provided on both sides of the second guide pillar 3. Each heating component includes a connecting plate 5 and two heating devices 7, which are fixedly connected to the connecting plate 5. The connecting plate 5 and the two heating devices 7 are arranged in a U-shape. Each heating device 7 includes an electric heating plate, a shell, and other structures, and can dry the coated substrate. A heating channel 8 is formed between the two heating devices 7 for the base fabric to pass through. The heating components are inclined, and the two sets of heating components are arranged in an inverted V-shape.

[0022] Specifically, the substrate passes through (refer to) Figure 4 ): The left side is below the first guide post 2, the left heating channel 8, and above the second guide post 3; the right side is below the first guide post 2 and the right side heating channel 8; the side of the operation box 1 away from the heat preservation box 4 can be set as a detachable structure to facilitate the loading of the substrate.

[0023] Considering that when the coating machine and winding device stop working, the substrate will dry quickly if it stays in the operating box 1 for a long time. At this time, although the heating device 7 has stopped heating, the temperature of the heating device 7 is still high, which can easily cause the substrate to deform. In order to avoid the substrate deformation, a through groove 9 is provided on the side wall of the operating box 1 for the heating component to pass through. The operating box 1 is connected to the heat preservation box 4 through the through groove 9. The top of the operating box 1 is connected to the exhaust pipe 18, and an exhaust fan 10 is installed inside the exhaust pipe 18.

[0024] In actual use, when the coating machine and winding device stop working, the heating component is recycled from the through groove 9 into the heat preservation box 4, so that the heating component is away from the substrate. At the same time, the exhaust fan 10 is started, and the exhaust fan 10 carries away the residual heat through the exhaust pipe 18 to prevent the residual heat from affecting the quality of the substrate.

[0025] Furthermore, after the heating components are recycled into the heat preservation box 4, they can achieve the effect of heat preservation, and can be quickly heated to the set temperature in the next drying operation, reducing energy consumption.

[0026] In addition, exhaust fans 10, exhaust pipes 18 and other structures can be installed at the bottom of the control box 1, which can be adjusted according to the specific usage.

[0027] A sliding groove 11 is provided through the top of the side wall of the control box 1. A sliding plate 12 is slidably arranged inside the sliding groove 11 and is attached to the lower surface of the top of the control box 1. A second round rod 15 is fixedly connected to one end of the sliding plate 12 located outside the control box 1.

[0028] During the drying process, the slide plate 12 closes the bottom of the exhaust pipe 18 to prevent heat from escaping; while during the heat dissipation process, the slide plate 12 slides outward from the inside of the slide groove 11, causing the bottom of the exhaust pipe 18 to open, without affecting the operation of the exhaust fan 10.

[0029] The interior of the insulated box 4 is equipped with a connecting frame 13, with both ends of the connecting frame 13 fixedly connected to two connecting plates 5 respectively. A first round rod 14 is fixedly connected to the connecting frame 13, and the insulated box 4 has a round hole for the first round rod 14 to pass through. A vertical plate 16 is fixedly connected to the end of the second round rod 15 away from the sliding plate 12, and the end of the vertical plate 16 away from the second round rod 15 is fixedly connected to the first round rod 14. The vertical plate 16 is set so that the first round rod 14 and the second round rod 15 can move synchronously.

[0030] A first electric push rod 17 is fixedly connected to the outer wall of the control box 1, and a vertical plate 16 is fixedly connected to the telescopic end of the first electric push rod 17.

[0031] To separate the insulation box 4 and the control box 1, a closing assembly is provided at the through slot 9, and the closing assembly is located inside the insulation box 4. The closing assembly includes a baffle 6 and a second electric push rod 19. The second electric push rod 19 is fixedly connected to the outer wall of the control box 1, and the baffle 6 is fixedly connected to the telescopic end of the second electric push rod 19. When the telescopic end of the second electric push rod 19 extends, the baffle 6 closes the through slot 9; when the telescopic end of the second electric push rod 19 retracts, the baffle 6 is offset from the through slot 9, and the through slot 9 opens.

[0032] When the coating machine and winding device stop working, the telescopic end of the second electric push rod 19 is retracted, causing the through groove 9 to open; then the telescopic end of the first electric push rod 17 is extended, and the slide plate 12 is driven to slide outward from the inside of the slide groove 11 through the second round rod 15, causing the bottom end of the exhaust pipe 18 to open; at the same time, the first round rod 14 drives the heating component to retract from the through groove 9 into the interior of the heat preservation box 4 through the connecting frame 13, and the heating component moves away from the substrate. After the heating component has completely entered the interior of the heat preservation box 4, the telescopic end of the second electric push rod 19 is extended, and the baffle 6 closes the through groove 9, isolating the heat preservation box 4 and the operation box 1; the exhaust fan 10 is started, and the exhaust fan 10 quickly exhausts the residual heat through the exhaust pipe 18.
