Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate processing, and specifically, to a glue coating and drying device for the production of reflective aluminum plates. Background Art

[0002] Reflective aluminum can be applied to fields such as signs, nameplates, vehicle license plates, vehicle body reflectors, and building decoration, with a very wide range of applications. It mainly has a reflective glue layer and a protective glue layer coated on the upper end of the aluminum base, and needs to go through multiple processes such as unwinding, coating an adhesive glue layer, bonding a metal reflective layer, drying, coating a reflective glue layer, drying, coating a protective glue layer, drying, and winding. In the prior art, the drying devices commonly used on existing aluminum plate production lines mostly use a blower to directly blow dry the surface of the aluminum base to achieve aluminum drying, and rely on the rapid flow of air to improve the drying effect.

[0003] The utility model with the authorization announcement number CN219693800U provides a drying device for aluminum plate finished products to prevent primer scratching. By installing a conveying mechanism, when the device body is performing a drying operation on the aluminum plate, it can complete the placement of the aluminum plate by adjusting the position of the U-shaped clamping plate, solving the problem that the bottom surface of the aluminum plate is easily scratched during the traditional conveying process, and improving the protection performance of the drying device for aluminum plate finished products to prevent primer scratching.

[0004] When drying the paint layer or glue layer on the surface of the aluminum plate by the above-mentioned drying device for aluminum plate finished products, there is a problem that the U-shaped clamping plate blocks the bottom area of the aluminum plate, resulting in the hot air flow being unable to directly blow the side surface of the aluminum plate comprehensively, so that the paint layer or glue layer on the aluminum plate cannot be evenly dried, reducing the drying quality. In view of this, we propose a glue coating and drying device for the production of reflective aluminum plates. Summary of the Invention

[0005] The purpose of the present utility model is to provide a glue coating and drying device for the production of reflective aluminum plates to solve the problems raised in the above background art.

[0006] To achieve the above purpose, one of the purposes of the present utility model is to provide a glue coating and drying device for the production of reflective aluminum plates, including a box body. A C-shaped frame is arranged inside the box body. The bottom surface inside the C-shaped frame is used to place the aluminum plate. A pressing plate is arranged above the aluminum plate inside the C-shaped frame. A limiting mechanism is arranged on the pressing plate, and the limiting mechanism is used to drive the pressing plate to move vertically. The two sides of the C-shaped frame are symmetrically hinged with turning plates near the top. When the limiting mechanism drives the pressing plate to move vertically downward to press the aluminum plate downward, the limiting mechanism drives the two turning plates to turn upward synchronously. A drying mechanism is arranged on the top of the box body, and a displacement mechanism is arranged at the bottom of the box body. The displacement mechanism is used to drive the C-shaped frame to move horizontally.

[0007] As a further improvement of the technical solution, the limiting mechanism includes extension rods symmetrically and fixedly connected to the upper surface of the pressing plate. A sleeve is slidably sleeved on the outer side of each extension rod. The upper ends of the two sleeves slidably penetrate through the upper side wall of the C-shaped frame and are fixedly connected to a top plate. A threaded rod is rotatably connected to the upper surface of the C-shaped frame, and the threaded rod is threadedly connected to the top plate. An internal spring is arranged inside the sleeve, and two ends of the internal spring are respectively fixedly connected to the upper end surface of the extension rod and the lower surface of the top plate.

[0008] As a further improvement of the technical solution, four blocking frames are fixedly connected to the positions of the side wall of the top plate near the four corners. When the four blocking frames respectively contact the sides of the two flipping plates away from the C-shaped frame, the flipping plates are in a vertical state. Two spring telescopic rods are fixedly connected to the lower surface of the box body. The two flipping plates in the vertical state respectively contact one end of the two spring telescopic rods, so that the spring telescopic rods are in an elastically contracted state.

[0009] As a further improvement of the technical solution, the drying mechanism includes a flow dividing cylinder arranged inside the box body. The flow dividing cylinder is of an N-shaped structure. A plurality of air outlets are fixedly connected to the side of the vertical section of the flow dividing cylinder close to the C-shaped frame. The plurality of air outlets are arranged in a vertical array. A hot air blower is fixedly connected to the top of the box body. An air supply pipe is fixedly connected to the bottom of the hot air blower, and the lower end of the air supply pipe is fixedly connected to the flow dividing cylinder.

[0010] As a further improvement of the technical solution, the displacement mechanism includes a moving groove opened at the inner bottom of the box body. A lead screw is rotatably connected inside the moving groove. A moving frame is threadedly connected to the lead screw. The moving frame is slidably arranged inside the moving groove. The C-shaped frame is fixedly connected to the upper surface of the moving frame. A motor is fixedly connected to one side of the box body. The output shaft of the motor extends into the moving groove and is fixedly connected to the lead screw coaxially.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the glue coating and drying device for producing reflective aluminum plates, after keeping the two flipping plates in a vertical state to facilitate clamping and fixing the aluminum plates in a vertical posture inside the C-shaped frame, the flipping plates automatically flip upwards to a horizontal state. Then, when hot air blows out from the air outlets to dry the glue layer of the aluminum plates, the flipping plates will not block part of the hot air flow from contacting the glue layer of the aluminum plates, thereby realizing the comprehensive and uniform drying of the glue layers on both sides of the aluminum plates, improving the drying efficiency and drying quality.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0025] Please refer to Figure 1 and Figure 2As shown in the figure, one of the purposes of this embodiment is to provide a glue - applying and drying device for the production of reflective aluminum plates, including a box body 1. Inside the box body 1, there is a C - shaped frame 2. The bottom surface inside the C - shaped frame 2 is used to place aluminum plates. On both sides of the C - shaped frame 2 near the top, there are symmetrically hinged turning plates 4. When the two turning plates 4 are in the vertical state, they play a limiting role on the aluminum plates placed inside the C - shaped frame 2. That is, after the aluminum plates are placed at the position between the two turning plates 4 on the bottom surface inside the C - shaped frame 2, the two turning plates 4 respectively contact both sides of the aluminum plates, restricting the aluminum plates from tipping to both sides and preventing the aluminum plates from tipping over, thus standing the aluminum plates inside the C - shaped frame 2. Above the aluminum plates inside the C - shaped frame 2, there is a pressing plate 3. On the pressing plate 3, there is a limiting mechanism 5. The limiting mechanism 5 is used to drive the pressing plate 3 to move vertically. When the limiting mechanism 5 drives the pressing plate 3 to move vertically downward so that the pressing plate 3 presses the aluminum plates downward, the pressing plate 3 cooperates with the bottom surface inside the C - shaped frame 2 to clamp and fix the aluminum plates inside the C - shaped frame 2, ensuring the stability of the aluminum plates during drying.

[0026] On the top of the box body 1, there is a drying mechanism 6. On the bottom of the box body 1, there is a displacement mechanism 7. The displacement mechanism 7 is used to drive the C - shaped frame 2 to move horizontally. After the aluminum plates are clamped and fixed inside the C - shaped frame 2, one side of the box body 1 is set as an opening. The farther away from the opening inside the box body 1, the deeper the position is. During the process of driving the C - shaped frame 2 and the aluminum plates to move deeper into the box body 1 through the displacement mechanism 7, the C - shaped frame 2 and the aluminum plates will pass through the drying mechanism 6. The drying mechanism 6 evenly dries the glue layers on both sides of the aluminum plates, thereby improving the drying efficiency and drying quality of the glue applied on the aluminum plates.

[0027] To drive the C - shaped frame 2 to move horizontally, the structure of the displacement mechanism 7 is refined as follows. Refer to Figure 3 , the displacement mechanism 7 includes a moving groove 71 opened at the bottom inside the box body 1. Inside the moving groove 71, there is a screw rod 72 rotatably connected. A moving frame 74 is thread - connected to the screw rod 72. The moving frame 74 is slidably arranged inside the moving groove 71. The C - shaped frame 2 is fixedly connected to the upper surface of the moving frame 74. On one side of the box body 1, there is a fixed - connected motor 73. The output shaft of the motor 73 extends into the moving groove 71 and is coaxially fixedly connected to the screw rod 72. After the motor 73 is started, its output shaft drives the screw rod 72 to rotate. Through the threaded connection between the screw rod 72 and the moving frame 74, the moving frame 74 drives the C - shaped frame 2 to move horizontally along the axis direction of the screw rod 72, and then smoothly moves the C - shaped frame 2 and the aluminum plates deeper into the box body 1, so that the drying mechanism 6 dries the aluminum plates.

[0028] To enable the drying mechanism 6 to evenly dry the glue layers on both sides of the aluminum plates, the structure of the drying mechanism 6 is refined as follows. Refer to Figure 5, the drying mechanism 6 includes a flow dividing cylinder 61 arranged inside the box body 1. The flow dividing cylinder 61 is of an N-shaped structure. A plurality of air outlets 62 are fixedly connected to one side of the vertical section of the flow dividing cylinder 61 close to the C-shaped frame 2. The plurality of air outlets 62 are arranged in a vertical array. A hot air blower 63 is fixedly connected to the top of the box body 1. A air supply pipe is fixedly connected to the bottom of the hot air blower 63. The lower end of the air supply pipe is fixedly connected to the flow dividing cylinder 61. After the hot air blower 63 is started, dry hot air flow is blown into the flow dividing cylinder 61 through the air supply pipe. The hot air flow in the flow dividing cylinder 61 is then blown out through the plurality of air outlets 62. When the C-shaped frame 2 and the aluminum plate pass through the inside of the flow dividing cylinder 61, the plurality of air outlets 62 are respectively located on both sides of the aluminum plate. After the hot air flow blown out by the vertically arranged plurality of air outlets 62 contacts both sides of the aluminum plate, the adhesive layers in the vertical areas on both sides of the aluminum plate are dried. When the aluminum plate slowly moves horizontally in the flow dividing cylinder 61, the vertical areas on both sides of the aluminum plate that have contacted the hot air flow continuously expand horizontally until all areas on both sides of the aluminum plate have been baked by the hot air flow, thereby realizing uniform drying of the adhesive layer of the aluminum plate and improving the drying efficiency and drying quality.

[0029] However, the flipping plate 4 in the vertical state will block some areas on both sides of the aluminum plate, and the hot air flow blown out by the air outlets 62 cannot blow to the areas on the aluminum plate blocked by the flipping plate 4, resulting in poor drying effect of the adhesive layer in this area. To solve this problem, the structure of the limiting mechanism 5 is refined as follows. Refer to Figure 4 and Figure 6 , the limiting mechanism 5 includes extension rods 52 symmetrically and fixedly connected to the upper surface of the pressing plate 3. Sleeve tubes 53 are slidably sleeved on the outer sides of the extension rods 52. The upper ends of the two sleeve tubes 53 slidably penetrate through the upper side wall of the C-shaped frame 2 and are fixedly connected to a top plate 54. The two sleeve tubes 53 limit the top plate 54 to only move vertically. A threaded rod 51 is rotatably connected to the upper surface of the C-shaped frame 2. The threaded rod 51 is threadedly connected to the top plate 54. When the threaded rod 51 is rotated, due to the threaded connection between the threaded rod 51 and the top plate 54, the top plate 54 moves vertically downward under the guiding action of the two sleeve tubes 53. An internal spring 55 is arranged inside the sleeve tube 53. Both ends of the internal spring 55 are respectively fixedly connected to the upper end surface of the extension rod 52 and the lower surface of the top plate 54. The downward moving top plate 54 drives the pressing plate 3 to move downward synchronously through the sleeve tube 53, the internal spring 55 and the extension rod 52. When the pressing plate 3 contacts the aluminum plate vertically placed on the inner bottom surface of the C-shaped frame 2 and clamps and fixes the aluminum plate, the positions of the pressing plate 3 and the extension rod 52 remain unchanged. The downward moving top plate 54 drives the sleeve tube 53 to move towards the pressing plate 3, causing the internal spring 55 to elastically contract. The resilience of the internal spring 55 presses the extension rod 52 and the pressing plate 3 downward, strengthening the clamping and fixing of the aluminum plate by the pressing plate 3.

[0030] Four retaining frames 57 are fixedly connected to the positions of the side walls of the top plate 54 near the four corners. When the pressing plate 3 does not clamp and fix the aluminum plate, the four retaining frames 57 are respectively in contact with the sides of the two flipping plates 4 away from the C-shaped frame 2, and the flipping plates 4 are in a vertical state. Two spring telescopic rods 56 are fixedly connected to the lower surface of the box body 1. In the vertical state, the two flipping plates 4 are respectively in contact with one end of the two spring telescopic rods 56, so that the spring telescopic rods 56 are in an elastically contracted state. The force of the spring telescopic rods 56 rebounding pushes the flipping plates 4 in the direction away from the C-shaped frame 2, and the retaining frames 57 limit the flipping of the flipping plates 4, so that the flipping plates 4 are kept in a vertical state, and the flipping plates 4 prevent the aluminum plate from tipping over. When the top plate 54 drives the pressing plate 3 to move downward to the position in contact with the aluminum plate and clamps and fixes the aluminum plate, the top plate 54 drives the retaining frames 57 to move below the flipping plates 4. After the retaining frames 57 are separated from the flipping plates 4, the spring telescopic rods 56 rebound and push the flipping plates 4 to flip upward until the flipping plates 4 flip to a horizontal state. Thus, when the hot air is blown out from the air outlet 62 to dry the adhesive layer of the aluminum plate, the flipping plates 4 do not block part of the hot air flow from contacting the adhesive layer of the aluminum plate, so that the adhesive layers on both sides of the aluminum plate can be dried comprehensively and evenly.
