[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. In order to test some properties of the paint after it is applied to the product, during the paint production process, the produced paint needs to be sprayed on the corresponding sample plate, and then the sample plate needs to be fixed on the fixture inside the oven to heat the sample plate and dry the paint.

[0003] In conventional ovens for drying anti-corrosion coatings, the limited internal space makes it difficult to install and remove the sample plates from the fixture. Furthermore, the sample plates are fixed in the oven, resulting in varying hot air temperatures at different locations within the oven, which in turn causes uneven heating of the coating on the sample plates and reduces drying efficiency. Therefore, the present invention provides an oven for anti-corrosion coatings. Utility Model Content

[0004] The utility model proposes an oven for anti-corrosion coatings, which solves the problems in the related art of an oven for drying anti-corrosion coatings, such as limited internal space in the oven during the process of fixing a sample plate, inconvenience in installing and removing the sample plate on a fixture, different hot air temperatures at different positions inside the oven, uneven heating of the coating on the sample plate, and low drying efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, this embodiment proposes an oven for anti-corrosion coatings, including a box body 1, a cover 11 is rotatably connected to the top of the box body 1, two vertical plates 2 are fixed to the inner bottom wall of the box body 1, and a slide groove 21 is provided on the side walls of the vertical plates 2. The sides of the vertical plates 2 that are away from each other are slidably connected to a lifting plate 22, and the vertical plates 2 are slidably connected to a lifting rod 23 through the slide groove 21. The lifting rods 23 are rotatably connected to the lifting plate 22, and the ends of the lifting rods 23 that are close to each other are commonly fixed to a placement frame 24, and teeth 25 are provided on the inner side walls of the slide groove 21, and an insertion rod 26 is fixed on the opposite sides of the slide groove 21, and a tooth groove adapted to the teeth 25 and a through groove adapted to the insertion rod 26 are provided on the outer side walls of the lifting rod 23, and the lifting rod 23 is meshed with the teeth 25 through the tooth groove.

[0024] Two cylinders 3 are fixed on the inner bottom wall of the box body 1. The telescopic ends of the cylinders 3 are fixed to the lifting plate 22. The lifting plate 22 is fixed to two limiting oblique blocks 31 on one side of the vertical plate 2. The vertical plate 2 is provided with a limiting oblique groove 32 adapted to the limiting oblique block 31 on one side of the lifting plate 22. The lifting plates 22 are slidably connected to the limiting oblique groove 32 through the limiting oblique blocks 31. By setting two limiting oblique blocks 31, the two lifting plates 22 are slidably connected to the limiting oblique groove 32 through the limiting oblique blocks 31, and the lifting plates 22 are limited so that the cylinder 3 can be extended and retracted. The end drives the lifting plate 22 to slide stably along the vertical plate 2; the inner bottom wall of the placement frame 24 is provided with two sets of vertical rods 6. By setting two sets of vertical rods 6, the vertical rods 6 are in conflict with both sides of the sample plate, and the placement frame 24 drives the sample plate to rotate to prevent the sample plate from deflecting; a pair of arc-shaped stoppers 4 are fixed on the opposite side walls inside the box body 1, and the top of the lifting plate 22 is provided with an arc-shaped groove 41 adapted to the arc-shaped stopper 4. By setting a pair of arc-shaped stoppers 4, when the cylinder 3 drives the lifting plate 22 to slide upward, the lifting plate 22 passes through the arc-shaped groove 41 and the arc-shaped stopper The stopper 4 interferes to prevent the lifting plate 22 from driving the limiting inclined block 31 to slide upward and separate from the limiting inclined groove 32; a plurality of rectangular grooves 7 are provided on the opposite sides of the placement frame 24, and the inner side walls of the rectangular grooves 7 are slidably connected with a card block 71, and a spring 72 is fixed between the card block 71 and the rectangular groove 7, and the side of the card block 71 close to the spring 72 is fixed with a connecting rod 73, and the end of the connecting rod 73 away from the card block 71 passes through the side wall of the placement frame 24 and is fixedly connected to a pull rod 74; arc-shaped short blocks 8 are fixed on both sides of the card block 71, and the inner side walls of the rectangular grooves 7 are relatively close. A card slot 81 is provided on both sides of the pair, and the card block 71 is slidably connected to the card slot 81 through an arc-shaped short block 8. By setting a plurality of card blocks 71, when the sample plate moves downward, the sample plate pushes the card blocks 71 on both sides thereof to slide along the rectangular groove 7 toward the two sides of the placement frame 24 until the sample plate is in contact with the inner bottom wall of the placement frame 24. Under the elastic action of the spring 72 itself, the spring 72 pushes the card block 71 to slide along the rectangular groove 7 toward the sample plate, so that one end of the card block 71 extends to the outside of the rectangular groove 7 and is in contact with the upper surface of the sample plate, thereby fixing the position of the sample plate on the placement frame 24.

[0025] In this embodiment, by opening the cover 11 and starting the cylinder 3, the cylinder 3 drives the two lifting plates 22 and the limiting oblique block 31 to slide upward along the limiting oblique groove 32 through the telescopic end, and the two lifting plates 22 drive the placement frame 24 to move upward between the two vertical plates 2 through the lifting rod 23. The teeth 25 engage the lifting rod 23 through the tooth groove, so that after the lifting rod 23 rotates to a certain angle, the lifting rod 23 is slidably connected with the insertion rod 26 through the through groove. Under the limiting action of the insertion rod 26, the two lifting rods 23 are prevented from rotating between the two vertical plates 2, thereby making the placement frame 24 maintain a horizontal state and move upward until the two lifting plates 22 contact the arc-shaped stopper 4 through the arc-shaped groove 41, so that the placement frame 24 is located at the top of the box body 1. By pushing the sample plate downward along the vertical rod 6 into the interior of the placement frame 24, the sample plate pushes the blocks 71 on both sides of the sample plate to slide along the rectangular groove 7 toward the sides of the placement frame 24 under the action of the inclined surface until the sample plate fits into the inner bottom wall of the placement frame 24. Under the elastic action of the spring 72 itself, the spring 72 pushes the block 71 to slide along the rectangular groove 7 toward the sample plate, so that one end of the block 71 extends to the outside of the rectangular groove 7 and fits into the upper surface of the sample plate, thereby fixing the position of the sample plate on the placement frame 24. The cover 11 is closed and the cylinder 3 is started. The cylinder 3 drives the two lifting plates 22 and the lifting rod 23 to slide downward through the telescopic end. The lifting rod 23 and the insertion rod After the teeth 26 are separated, the limit of the lifting rod 23 is released, and the teeth 25 engage the lifting rod 23 through the tooth grooves. After the lifting rod 23 moves downward to the middle position of the teeth 25, the cylinder 3 drives the lifting rod 23 to reciprocate up and down on one side of the teeth 25 through the two lifting plates 22. Under the action of the teeth 25, the lifting rod 23 drives the placement frame 24 and the sample plate to rotate forward and reverse inside the box body 1, and the sample plate is rotated and heated. After the drying is completed, the cover 11 is opened again and the cylinder 3 is started. The cylinder 3 drives the placement frame 24 to move upward through the two lifting plates 22 and the lifting rod 23, so that the placement frame 24 is located at the top of the box body 1. By pulling the placement frame 24 The pull rods 74 on both sides drive the blocks 71 on both sides of the sample plate to slide toward the two sides of the placement frame 24 through the connecting rods 73, so that the blocks 71 are separated from the sample plate, the limit on the sample plate is released, and the sample plate is taken out from the placement frame 24. The sample plate is installed and removed by moving the placement frame 24 to the top of the box body 1, which expands the operating space for workers to install and remove, and facilitates workers to install and remove the sample plate on the placement frame 24. By controlling the cylinder 3 to drive the placement frame 24 and the sample plate to rotate inside the box body 1, the sample plate is rotationally heated, and the position of the sample plate inside the box body 1 is changed, so that the paint on the surface of the sample plate is evenly heated, thereby improving the drying efficiency of the sample plate.

[0026] Example 2

[0027] like Figure 4As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a through hole is provided on the outer wall of the lifting plate 22, and the lifting plate 22 is rotatably connected to the lifting rod 23 through the through hole. A pair of annular protrusions 5 are fixed on the inner wall of the through hole, and a groove 51 adapted to the annular protrusion 5 is provided on the outer wall of the lifting rod 23, and the lifting rod 23 is rotatably connected to the annular protrusion 5 through the groove 51.

[0028] In this embodiment, a pair of annular protrusions 5 are fixedly connected to the lifting plate 22 through the through holes, and the two lifting rods 23 are rotatably connected to the annular protrusions 5 through the grooves 51, thereby limiting the lifting rods 23 and preventing the lifting rods 23 from sliding laterally along the inner wall of the through hole inside the lifting plate 22, thereby allowing the lifting rods 23 to rotate stably inside the lifting plate 22.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
