Description

Technical Field

[0001] This utility model relates to the field of water-based UV plastic coating materials, specifically a preheating processing device for water-based UV plastic coating materials. Background Technology

[0002] Water-based UV plastic coating material is an environmentally friendly coating specially designed for coating the surface of plastics (such as PVC, ABS, PC, PS, PET, etc.) and rubber products. Under ultraviolet (UV) light, it can quickly transform from a liquid state to a solid, hard coating within seconds.

[0003] Before curing, water-based UV plastic coating processes require preheating in an oven to completely evaporate the moisture in the coating. However, the hot air outlets of ovens are usually on both sides, while the materials inside the oven are in a fixed position. Even if there is a hot air circulation device inside the oven, the materials in each position will be heated unevenly, thus affecting the drying effect. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the hot air outlets of general ovens are located on both sides, while the materials placed inside the oven are in a fixed position. Even if there is a hot air circulation device inside the oven, it will still cause uneven heating of the materials in each position, thus affecting the drying effect. This utility model proposes a preheating processing device for water-based UV plastic coating materials.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a preheating processing device for water-based UV plastic coating materials, including an oven, wherein a rotating device is provided in the inner cavity of the oven;

[0006] The rotating device includes a mounting frame, an mounting plate is movably connected to the inner cavity of the mounting frame, a motor is fixedly connected to the inner cavity of the mounting plate, the output end of the motor passes through the mounting plate and is fixedly connected to a rotating column, the inner cavity of the rotating column is movably connected to the inner cavity of the mounting frame, and a hollow placement frame is fixedly sleeved on the surface of the rotating column, the number of which is five.

[0007] Preferably, each of the hollowed-out placement racks has a baffle fixedly fitted on its surface, and the height of the baffle is higher than the top of the hollowed-out placement rack.

[0008] Preferably, the surface of the rotating column is fixedly fitted with a reinforcing frame, and the number of the reinforcing frames is five. The top of each reinforcing frame is fixedly connected to the bottom of a hollow placement frame.

[0009] Preferably, the surface of the oven is provided with heat dissipation holes, and the number of heat dissipation holes is several, with one end of each heat dissipation hole extending into the inner cavity of the mounting frame.

[0010] Preferably, the top of the mounting plate is fixedly connected to a limiting block, and the number of limiting blocks is two. The top of the inner cavity of the mounting frame is provided with a limiting groove, and the number of limiting grooves is two. The inner cavity of each limiting groove is movably connected to the surface of a limiting block.

[0011] Preferably, each of the limiting blocks is fixedly fitted with a rubber sleeve, the surface of the rubber sleeve being in close contact with the inner cavity of the limiting groove, and the surface of the mounting bracket is provided with a storage groove.

[0012] Preferably, the surface of the mounting bracket is provided with a sliding groove, and the inner cavity of the sliding groove is movably connected to the surface of the rotating column.

[0013] The advantages of this utility model are:

[0014] This invention combines an oven and a rotating device. Materials requiring preheating and drying are placed on the surface of a perforated rack. A motor drives the rack to rotate slowly, indirectly changing the position of the materials. This allows materials in different positions to work with the oven's hot air circulation system to achieve a uniform drying effect. This solves the problem that in general ovens, the hot air outlets are on both sides while the materials inside are in a fixed position. Even with a hot air circulation system, this can lead to uneven heating of materials in different positions, thus affecting the drying effect. Attached Figure Description

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a preheating processing apparatus for water-based UV plastic coating materials. (Refer to...) Figure 1 and Figure 5 A preheating processing device for water-based UV plastic coating materials includes an oven 1, with a rotating device 2 installed inside the oven 1. The oven 1 includes a heating device, a hot air circulation device, a control system, an exhaust system, and a heat preservation system. Through the coordinated use of a series of devices, the materials inside that need to be dried are dried.

[0025] The rotating device 2 includes a mounting frame 206, an mounting plate 208 is movably connected to the inner cavity of the mounting frame 206, a motor 201 is fixedly connected to the inner cavity of the mounting plate 208, the output end of the motor 201 passes through the mounting plate 208 and is fixedly connected to a rotating column 202, the inner cavity of the rotating column 202 is movably connected to the inner cavity of the mounting frame 206, and a hollow placement frame 204 is fixedly sleeved on the surface of the rotating column 202, and the number of hollow placement frames 204 is five.

[0026] Reference Figure 3 Each hollowed-out placement rack 204 has a baffle 205 fixedly fitted on its surface, and the height of the baffle 205 is higher than the top of the hollowed-out placement rack 204;

[0027] Reference Figure 3 Five reinforcing frames 203 are fixedly fitted on the surface of the rotating column 202. The top of each reinforcing frame 203 is fixedly connected to the bottom of a hollow placement frame 204. The reinforcing frames 203 provide reinforcement and support for the position of the hollow placement frame 204, thereby improving the stability of the hollow placement frame 204 installed on the surface of the rotating column 202.

[0028] Reference Figure 2 and Figure 3 The surface of the oven 1 is provided with heat dissipation holes 207. There are several heat dissipation holes 207. One end of the heat dissipation hole 207 extends into the inner cavity of the mounting frame 206. The heat dissipation holes 207 are provided to dissipate the heat generated in the inner cavity of the mounting frame 206 and to prevent the motor 201 from being affected by excessive temperature.

[0029] Reference Figure 4 The top of the mounting plate 208 is fixedly connected to a limiting block 212, and there are two limiting blocks 212. The top of the inner cavity of the mounting frame 206 is provided with a limiting groove 210, and there are two limiting grooves 210. The inner cavity of each limiting groove 210 is movably connected to the surface of a limiting block 212. Through the cooperation of the limiting block 212 and the limiting groove 210, the mounting plate 208 moves on the surface of the mounting frame 206, while also preventing the mounting plate 208 from rotating, thereby indirectly preventing the position of the motor 201 from rotating, so that the motor 201 can smoothly drive the rotating column 202 to rotate.

[0030] Reference Figure 4 Each limiting block 212 has a rubber sleeve 211 fixedly fitted on its surface. The surface of the rubber sleeve 211 is in close contact with the inner cavity of the limiting groove 210. The surface of the mounting frame 206 has a storage groove 213. The rubber sleeve 211 increases the friction of the limiting block 212 sliding in the inner cavity of the limiting groove 210, thereby indirectly preventing the mounting plate 208 from moving easily and indirectly improving the stability of the rotation position of the hollow placement frame 204. The rubber sleeve 211 prevents the mounting plate 208 and motor 201 from being blocked by the inner wall of the mounting frame 206 when the rotating column 202 slides forward in the inner cavity of the sliding groove 209, which would prevent the rotating column 202 from sliding to the front of the inner cavity of the sliding groove 209 and ultimately result in insufficient space for the hollow placement frame 204 to move out of the inner cavity of the oven 1.

[0031] Reference Figure 3 and Figure 5 The surface of the mounting bracket 206 is provided with a sliding groove 209. The inner cavity of the sliding groove 209 is movably connected to the surface of the rotating column 202. The sliding groove 209 provides sliding space and guidance for the rotating column 202 to slide in the inner cavity of the mounting bracket 206, thereby improving the stability of the rotating column 202 sliding in the inner cavity of the mounting bracket 206.

[0032] Working Principle: The oven 1 includes a heating device, a hot air circulation device, a control system, an exhaust system, and a heat preservation system. These devices work together to dry the materials inside. To improve the uniformity of heating, a rotating device 2 rotates the materials. When drying is required, the oven lid is first opened, and the rotating column 202 or baffle 205 is pulled outwards. The rotating column 202 or baffle 205 ultimately drives the motor 201 to move outwards. The motor 201 then moves the mounting plate 208, which in turn moves the limiting block 212 into the inner cavity of the limiting groove 210. Simultaneously, the rotating column 202 slides into the inner cavity of the sliding groove 209 until it reaches the frontmost side of the sliding groove 209. This indirectly moves the hollowed-out placement rack 204 outwards from the inner cavity of the oven 1, facilitating the placement of materials requiring drying and preheating. The material is placed on the surface of the hollowed-out placement rack 204. To prevent the mounting plate 208 and motor 201 from getting stuck in the inner cavity of the mounting rack 206, a storage slot 213 with the same shape as its front side is opened. After the material is placed on the surface of the hollowed-out placement rack 204, the rotating column 202 is pushed into the inner cavity of the oven 1 to the initial position. At this time, due to the damping of the rubber sleeve 211, the movement of the motor 201 during operation is indirectly prevented to a certain extent, and the stability of the position of the hollowed-out placement rack 204 during rotation is also improved to a certain extent. Then, the oven door is closed and the oven 1 is started. At the same time, the motor 201 will start working. The output end of the motor 201 slowly drives the rotating column 202 to rotate, and the rotating column 202 drives the hollowed-out placement rack 204 to rotate slowly, so that the position of the material on the surface of the hollowed-out placement rack 204 rotates slowly. Through rotation, each material is evenly close to the hot air outlets on both sides of the inner cavity of the oven 1, thereby improving the uniformity of the material heating.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
