Description

Technical Field

[0001] The utility model relates to the technical field of coating and drying, in particular to an integral oven. Background Art

[0002] An oven is an important machine in the coating operation. Generally, in the coating operation, it is necessary to unwind the substrate, apply glue, dry, and wind up the substrate. The oven is an essential mechanical equipment in the drying step. At present, the existing dryer is usually as shown in a drying device disclosed in CN210497116U, which includes a hull and a bracket fixedly installed below the hull for supporting the hull. An air duct assembly is provided on the back of the hull. There are three layers of air nozzles arranged in an S-shaped distribution inside the hull. A driving roller for driving the substrate is provided above or below the air nozzles. The driving roller includes a driving roller and a semi-driving roller. A single-section oven drives the substrate in a three-layer S-shaped tape-running manner and dries it. In this patent, the top layer of the oven equipment is opened by a cylinder, and the top structure of the oven equipment is opened by a cylinder.

[0003] The dryer designed in this way with the cylinder-opening method has requirements for the actual space of the factory building during actual installation and use. Usually, the factory building needs to have a height of at least 5.5 meters to meet the installation and use requirements of the dryer. For relatively low factory buildings, the existing cylinder-opening dryers cannot be installed or used. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: In order to overcome the deficiencies of the prior art, the utility model provides an integral oven. An exhaust hood is integrated in the oven box body. The top layer of the oven can complete the drying operation without using a cylinder to open it, and it is applicable to factory buildings with relatively low and narrow spaces.

[0005] The technical solution adopted by the utility model to solve its technical problem is: An integral oven for drying the coated substrate, including an oven box body, which has an inner cavity. A conveying bracket is arranged in the inner cavity along the conveying direction of the substrate. A number of oven rollers are arranged in sequence along the conveying direction on the conveying bracket. An air outlet pipe communicated with an external air source pipeline is arranged in the oven box body. A number of air nozzles are arranged on the air outlet pipe. The air outlet direction of the air nozzles points to the direction where the oven rollers support the substrate. An air exhaust port is opened on the upper end surface of the oven box body. An exhaust hood is connected and fixed below the air exhaust port. The exhaust hood covers the upper part of the oven rollers.

[0006] In the above solution, compared with the traditional oven with a cylinder top-opening type that requires a relatively high height for the workshop floor, in this application, a nozzle and an exhaust hood are integrated inside the oven box. The internal space of the box is reasonably arranged and utilized, and the blowing and exhaust operations required for drying can be achieved without opening the upper layer of the oven. The oven does not need to be opened by a cylinder, so the installation limitation of the overall installation height of the oven can be effectively reduced, and it is effectively applicable to workshops with a relatively low floor height.

[0007] Further, the number of the air outlet pipes is two, and they are respectively fixed at the bottom of both sides of the exhaust hood along the substrate conveying direction. The nozzles are arranged on the air outlet pipes and supplied with air by the air outlet pipes. The air outlet pipes are arranged at the bottom of the exhaust hood, making reasonable and effective use of the space.

[0008] Further, an opening and closing door is opened on any one side of the box body on both sides of the oven box corresponding to the conveying direction. Through the design of the opening and closing door, it can be opened according to the drying and maintenance requirements, which is convenient for operating the inside of the oven box.

[0009] Furthermore, opening and closing doors are opened on both sides of the box body on both sides of the oven box corresponding to the conveying direction, and the opening and closing doors on both sides are arranged staggeredly in the height direction. The staggered arrangement further optimizes the orientation of opening the door.

[0010] Preferably, the opening and closing door is hinged to the oven box through a hinge.

[0011] The beneficial effect of the present utility model is that the integral oven provided by the present utility model has a reasonable structural design. The exhaust hood is integrally arranged inside the oven box, and there is no need to separately design a cylinder to cover the upper layer of the oven, which can effectively save the space required for the installation and use of the cylinder and is suitable for installation in low workshops.

[0016] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model, and directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents.

[0017] As Figures 1 to 2 shown, an integral oven for drying the coated substrate is the optimal embodiment of the present utility model.

[0018] The integral oven includes an oven body 1, and the oven body 1 has an inner cavity 7. The inner cavity 7 is used to arrange and install various mechanisms for heating, drying, blowing and exhausting air.

[0019] As Figure 1 shown, in the layout of the inner cavity 7, a conveying bracket 9 is arranged in the inner cavity 7 of the oven body 1 along the substrate conveying direction, and a plurality of oven rollers 5 are arranged in sequence along the conveying direction on the conveying bracket 9. The oven rollers 5 are driven by a speed reducer to rotate, so as to realize the conveying and drying operation of the material to be dried in the oven.

[0020] During drying, in order to facilitate air exhaust, as Figure 1 and Figure 2 shown, an air exhaust port 2 is opened on the upper end surface of the oven body 1. The lower end of the air exhaust port 2 is connected and fixed with an exhaust hood 4 through a hoisting structure 11, and the exhaust hood 4 is externally covered above the oven rollers 5. An air outlet pipe 3 communicating with an external gas source pipeline is arranged in the oven body 1. A plurality of air nozzles 8 are evenly distributed at intervals on the air outlet pipe 3, and the air outlet direction of the air nozzles 8 points to the direction where the oven rollers 5 support the substrate. The number of the air outlet pipes 3 is two, and they are respectively fixed at the two bottom sides of the exhaust hood 4 along the substrate conveying direction. The air nozzles 8 are arranged on the air outlet pipes 3 and are supplied with air by the air outlet pipes 3. The air outlet pipes 3 are integrally arranged at the bottom of the exhaust hood 4, and no additional bracket needs to be designed, and they can be positioned along the exhaust hood 4, further rationally and effectively utilizing the space.

[0021] As Figure 2 shown, corresponding to the opening and inspection of the inner cavity 7 of the oven body 1 required during the drying operation process and oven maintenance and repair, for this purpose, opening doors 6 are opened on both sides of the oven body 1 corresponding to the two sides in the conveying direction, and the opening doors 6 are hinged to the oven body 1 through hinges.

[0022] At the same time, in this embodiment, the position of opening the door is further optimized, that is, the opening doors 6 on both sides are arranged staggeredly, one above the other in the height direction. They can be opened according to the drying and maintenance requirements, which is convenient for operating the inside of the oven body 1. At the same time, the staggered distribution is convenient for opening the door operation and maintenance at different positions.

[0023] The integrally designed oven, compared with the traditional cylinder-lifted oven that has a relatively high requirement for the height of the workshop, makes more reasonable use of the space inside the oven. The air nozzles 8 and the exhaust hood 4 are integrated in the oven body 1, and the blowing and exhaust operations required for drying can be realized without opening the upper layer of the oven. The oven does not need to be lifted by a cylinder, so the installation limitation of the overall installation height of the oven can be effectively reduced, and the space required for the installation and use of the cylinder can be effectively saved. It is suitable for workshops with relatively low ceilings and has good market prospects.

[0024] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can make various changes and modifications completely within the scope not deviating from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
