Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating board processing technology, specifically a coating board drying oven. Background Technology
[0002] In the production process of coated panels, the coatings applied to the surface of the panels usually contain volatile components such as solvents. These components need to be removed by drying to form a solid coating with certain properties. The drying process can not only improve the drying speed of the coating, but also improve the quality and performance of the coating, such as enhancing the adhesion, hardness, gloss, and corrosion resistance of the coating.
[0003] After the existing coated boards are processed, they need to be dried. Traditionally, the coated boards are placed directly inside the oven, and heat is generated by resistance wires to dry them. However, the resistance wires are often located at the top or bottom of the oven, making it difficult to dry most of the coated boards on the racks evenly. This results in poor drying effect and can easily cause quality and aesthetic problems with the coated boards. To address these issues, an improved and upgraded coated board drying oven is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a coating board drying oven to solve the technical problems of uneven and insufficient drying of coating boards and poor drying effect in existing devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a paint panel drying oven, comprising an oven cabinet, a sealed cabinet door rotatably mounted on the outer wall of the oven cabinet, a transparent glass cover inside the sealed cabinet door, a sealing structure between the oven cabinet and the sealed cabinet door, a placement rack fixedly mounted inside the oven cabinet, a plurality of paint panels placed inside the placement rack, a resistance wire fixedly mounted inside the oven cabinet directly below the placement rack, a blower structure located inside the oven cabinet behind the placement rack, the blower structure comprising a blower, the blower fixedly mounted on a support plate with one end of the support plate fixedly mounted on the outer wall of the oven cabinet, a connecting pipe connected to the output end of the blower with a U-shaped pipe at one end, air boxes fixedly connected to both ends of the U-shaped pipe, and two air outlets symmetrically opened on the outer wall of each air box.
[0006] Furthermore, one end of the connecting pipe extends through the inside of the oven cabinet and the extended end is fixedly connected to a U-shaped pipe. Both of the bellows are fixedly installed on the inner wall of the oven cabinet, and the two bellows are the same size.
[0007] Furthermore, the outer air outlets of the two air boxes are rectangular in shape, and a filter screen is fixedly installed inside the air outlet, with a number of filter holes inside the filter screen.
[0008] Furthermore, the sealing structure includes a sealing ring, which is fixedly installed on the inner wall of the sealed cabinet door. A fixing rod is fixedly installed on one side of the inner wall of the sealed cabinet door, and one end of the fixing rod passes through the sealing ring.
[0009] Furthermore, a limiting frame is provided inside the oven cabinet on the front side of the placement rack. The limiting frame has a placement groove inside, and a sealing gasket is installed inside the placement groove. The sealing ring and the sealing gasket are adapted to the size of the placement groove.
[0010] Furthermore, two hinge seats are symmetrically fixed on the outer wall of the oven cabinet on one side of the sealed cabinet door. A pressing plate is rotatably installed inside the hinge seat, and a clamping tube is rotatably installed on the outer wall of the pressing plate. The clamping tube is U-shaped.
[0011] Furthermore, one end of the connecting pipe is connected to the connecting block, and the connecting block is fixedly installed on the outer wall of the sealed cabinet door. The connecting pipe and the connecting block are compatible.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1) By setting up a blower structure, when the coating board inside the oven is dried by the resistance wire, the blower drives the U-shaped tube on the connecting pipe to blow the air out through the air outlet on the air box, thereby accelerating the circulation speed of hot air inside the oven, which is conducive to the uniform drying of the coating board inside the oven and speeding up the drying speed of the coating board.
[0014] 2) By setting up a sealing structure, when the operator places the paint board on the placement rack, the sealing ring and the sealing gasket on the limit frame are squeezed together by closing the sealing cabinet door to make it seal. Finally, the pressing plate drives the clamping pipe and the clamping block to tighten. This helps to improve the sealing performance of the oven when drying the paint board, avoids problems such as heat leakage caused by poor oven sealing, and saves energy and is environmentally friendly.

Detailed Implementation
[0021] 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.
[0022] Example 1
[0023] Combination Figures 1-5 A coating board drying oven includes an oven cabinet 1, a sealed cabinet door 2 rotatably mounted on the outer wall of the oven cabinet 1, a transparent glass cover inside the sealed cabinet door 2, a sealing structure 3 between the oven cabinet 1 and the sealed cabinet door 2, a placement rack 7 fixedly mounted inside the oven cabinet 1, a number of coating boards placed inside the placement rack 7, a resistance wire 6 fixedly mounted inside the oven cabinet 1 directly below the placement rack 7, a blower structure 4 located inside the oven cabinet 1 behind the placement rack 7, the blower structure 4 including a blower 41, the blower 41 fixedly mounted on a support plate with one end of the support plate fixedly mounted on the outer wall of the oven cabinet 1, a connecting pipe 42 connected to the output end of the blower 41, a U-shaped pipe 43 provided at one end of the connecting pipe 42, and bellows 44 fixedly connected to both ends of the U-shaped pipe 43, with two air outlets 45 symmetrically opened on the outer wall of each bellows 44.
[0024] See Figure 4 and Figure 5 Furthermore, one end of the connecting pipe 42 passes through the inside of the oven cabinet 1 and the extended end is fixedly connected to a U-shaped pipe 43. Both air boxes 44 are fixedly installed on the inner wall of the oven cabinet 1, and the two air boxes 44 are the same size. The air outlets 45 on the outside of the two air boxes 44 are rectangular in shape. A filter screen 46 is fixedly installed inside the air outlet 45, and the filter screen 46 has several filter holes inside.
[0025] Specifically, the connection pipe 42 and the U-shaped pipe 43 are relatively sealed. The inner wall of the U-shaped pipe 43 is attached to the inside of the oven cabinet 1 for easy support. The air outlet 45 of the air box 44 is set in a rectangle to accelerate the air blowing efficiency and thus drive the hot air in the oven to circulate fully, thereby drying the upper coating plate.
[0026] Example 2
[0027] See Figure 2 Based on Embodiment 1, the sealing structure 3 includes a sealing ring 35, which is fixedly installed on the inner wall of the sealed cabinet door 2. A fixing rod 36 is fixedly installed on one side of the inner wall of the sealed cabinet door 2, and one end of the fixing rod 36 passes through the sealing ring 35. A limiting frame 5 is provided inside the oven cabinet 1 in front of the placement rack 7. The limiting frame 5 has a placement groove inside, and a sealing gasket 51 is installed inside the placement groove. The sealing ring 35 and the sealing gasket 51 are adapted to the size of the placement groove. Two hinge seats 31 are symmetrically fixedly installed on the outer wall of the oven cabinet 1 on one side of the sealed cabinet door 2. A pressing plate 32 is rotatably installed inside the hinge seat 31, and a clamping tube 33 is rotatably installed on the outer wall of the pressing plate 32. The clamping tube 33 is U-shaped, and one end of the clamping tube 33 is connected to the clamping block 34. The clamping block 34 is fixedly installed on the outer wall of the sealed cabinet door 2, and the clamping tube 33 and the clamping block 34 are adapted to each other.
[0028] Specifically, the limiting frame 5 is rectangular in shape, which makes it easy for the sealing ring 35 on the fixing rod 36 of the sealing cabinet door 2 to be precisely pressed into the inside of the limiting frame 5, so that the sealing ring 35 and the sealing gasket 51 fit together to achieve a seal. Finally, the clamping pipe 33 is fastened to the clamping block 34 on the sealing cabinet door 2 by two sets of pressing plates 32, which improves the sealing effect. A transparent glass cover is set on the sealing cabinet door 2 to facilitate the operator to observe the internal coating board during drying.
[0029] In actual operation, when it is necessary to dry the coated panels, the operator first places multiple coated panels on the rack 7 inside the oven cabinet 1, and then rotates the sealing cabinet door 2, so that the fixing rod 36 on the back of the sealing cabinet door 2, along with the sealing ring 35, presses against the limiting frame 5 inside the oven cabinet 1. This causes the sealing ring 35 to press against the sealing gasket 51 in the placement groove, so that the sealing cabinet door 2 can be relatively sealed when closed. After closing, the two clamping pipes 33 are manually pulled so that one end of them engages with the clamping block 34. Then, the pressing plate 32 is pressed, which causes the clamping pipes 33 to tighten the sealing cabinet door 2 when it is closed, thus avoiding problems such as poor sealing effect and heat leakage when drying the coated panels. After the sealing cabinet door 2 is closed;
[0030] At this time, the external power supply is turned on, and the driving resistance wire 6 generates heat to heat and bake the paint panels inside the oven. The blower 41 on the drive support plate drives the generated cold air to flow through the connecting pipe 42 into the U-shaped pipe 43, which in turn delivers the cold air to the two air boxes 44. The air flow layout inside the air boxes 44 blows the hot air out through the two air outlets 45, continuously circulating and accelerating the flow speed. At the same time, a filter screen 46 is set at the air outlet 45 to block dust and prevent other impurities from affecting the operation of the air boxes 44, thereby realizing the temperature circulation inside the oven cabinet 1 and accelerating the drying speed of multiple paint panels.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
