Description

Technical Field

[0001] This utility model relates to the field of automotive film technology, specifically to a polyurethane flame-retardant invisible automotive film drying device. Background Technology

[0002] Car coating is a popular car maintenance service. After coating, a hard inorganic film layer is formed on the car paint surface, bonding tightly to the paint and improving its hardness and smoothness. It completely isolates the paint from the air and will never peel off without external force, significantly enhancing the gloss of the clear coat. During the production process, car coatings undergo a drying process to prevent defects such as watermarks, bubbles, and air streaks from appearing in the finished product.

[0003] Application No. CN202122642956.X discloses a polyurethane flame-retardant invisible automotive film drying device, including a drying box, a drying mechanism, and an adjusting mechanism. The drying box has a drying chamber inside. The drying mechanism includes a concentrating hood fixed to the inner wall of the drying chamber, a fan fixed to the concentrating hood, an electric heating plate disposed inside the concentrating hood, and a protective plate fixed to the bottom of the concentrating hood. In this utility model, the symmetrically arranged electric heating plates and fan can simultaneously perform convection drying on both the upper and lower surfaces of the automotive film, avoiding uneven or insufficient drying. Furthermore, the concentrating hood and protective plate can concentrate the generated heat, reducing heat loss and improving the drying effect. Simultaneously, the adjusting rollers and elastic elements can automatically adjust the tension of the automotive film during transport.

[0004] However, the drying mechanism of this device is fixedly installed inside the drying chamber. When a component, such as the electric heating plate or the fan, malfunctions, maintenance personnel must enter the drying chamber for repair. The operating space is extremely narrow, which not only increases the difficulty of maintenance but also may cause accidental damage to other normal components due to the inconvenience of operation. Moreover, the fixed installation structure makes it difficult to thoroughly clean the drying mechanism. After long-term use, dust and impurities easily accumulate on the electric heating plate, fan blades, and other parts, affecting heating efficiency and airflow uniformity, thereby reducing the drying effect. Therefore, a polyurethane flame-retardant invisible automotive film drying device is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a polyurethane flame-retardant invisible automotive film drying device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A polyurethane flame-retardant invisible automotive film drying device includes a drying box, the top of which has a groove for a first drying mechanism to be installed and inserted. The top of the first drying mechanism is fixedly connected to the output end of an electric cylinder, and the electric cylinder is fixedly installed on the top of a top plate.

[0008] A slide rail seat is inserted and installed on one side of the drying box. There are two slide rail seats. The two slide rail seats have a sliding groove on the side that is close to each other. The sliding groove is used for sliding installation of sliders. There are two sliders. The two sliders are fixedly installed on opposite sides of the second drying mechanism.

[0009] By adopting the above technical solution, the first drying mechanism is lifted and disengaged from the groove by an electric cylinder, and the second drying mechanism is pulled out with one click by a slide rail structure. Both mechanisms can be completely removed from the outside of the drying box. This design completely solves the maintenance problem of traditional fixed installation. During maintenance, there is no need for personnel to enter the narrow box to operate. The drying mechanism can be cleaned or replaced in an open space, avoiding the risk of accidental damage.

[0010] Specifically, a support rod is vertically fixed to the bottom end of the top plate, and there are four support rods. The top plate is located directly above the groove.

[0011] By adopting the above technical solution, the support rod provides rigid support to ensure that the top plate remains stable when the electric cylinder is operated. At the same time, the vertical fixed connection of the support rod ensures that the top plate is always located directly above the groove, ensuring that the first drying mechanism can be accurately embedded in the groove.

[0012] Specifically, one side of the drying oven is movably connected to a door via a hinge. The door has two slots inside, which are used for two slide rail seats to pass through.

[0013] By adopting the above technical solution, the compartment door is opened and closed by hinges, which makes it easy to open the compartment door and pull out the second drying mechanism during maintenance or cleaning; the slot and slide rail seat plug-in design allows the slide rail seat to be fixedly passed through when the compartment door is closed.

[0014] Specifically, a handle is fixedly connected to one side of the second drying mechanism, and a magnetic block is provided at the end of the slider away from the handle. The magnetic block is magnetically connected to the inner side of the slide groove.

[0015] By adopting the above technical solution, the handle provides a manual operation point, which makes it easy for users to pull the second drying mechanism along the slide when inspecting or cleaning; after the second drying mechanism is pushed into place, the magnetic block automatically adheres to one side of the slide, forming a magnetic fixation, preventing the mechanism from loosening or shifting during the drying process, and ensuring that the convective hot air from the second drying mechanism and the first drying mechanism acts stably on the car film.

[0016] Specifically, air inlets are provided on the outer side of the first drying mechanism and at the bottom of the second drying mechanism.

[0017] By adopting the above technical solution, the air inlet is used to provide an air circulation channel for the fans in the first and second drying mechanisms.

[0018] Specifically, the drying box has a feed inlet at one end.

[0019] By adopting the above technical solution, the feed port serves as an inlet channel through which the automotive film to be dried enters the drying chamber for drying.

[0020] The beneficial effects of this utility model are:

[0021] The polyurethane flame-retardant invisible car film drying device of this utility model uses an electric cylinder to drive the first drying mechanism to lift and detach from the groove, and a slide rail structure to realize the one-click pull-out of the second drying mechanism. Both mechanisms can be completely removed from the outside of the drying box. This design completely solves the maintenance problem of traditional fixed installation. During maintenance, there is no need for personnel to enter the narrow box to operate. The drying mechanism can be cleaned or replaced in an open space, avoiding the risk of accidental damage.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As one embodiment of this utility model, such as Figures 1-3As shown, the polyurethane flame-retardant invisible car film drying device of this utility model includes a drying box 2. The top of the drying box 2 is provided with a groove 1. The groove 1 is used for the first drying mechanism 8 to be installed and inserted. The top of the first drying mechanism 8 is fixedly connected to the output end of the electric cylinder 10. The electric cylinder 10 is fixedly installed on the top of the top plate 9.

[0029] A slide rail seat 4 is inserted and installed on one side of the drying box 2. There are two slide rail seats 4. A slide groove 5 is opened on the side of the two slide rail seats 4 that are close to each other. The slide groove 5 is used for sliding installation of slider 14. There are two sliders 14. The two sliders 14 are respectively fixedly installed on opposite sides of the second drying mechanism 13.

[0030] In use, the groove 1 allows the first drying mechanism 8 to descend precisely and embed under the drive of the electric cylinder 10, achieving docking with the drying box 2; at the same time, the slide rail seat 4 and the slide groove 5 provide guide rails, so that the second drying mechanism 13 can be smoothly pushed into the drying box 2 by the slider 14, ensuring that the first drying mechanism 8 and the second drying mechanism 13 can be quickly positioned above and below the automotive film during the drying process, forming a stable drying structure.

[0031] The present invention also includes a support rod 7 vertically fixedly connected to the bottom end of the top plate 9, and four support rods 7 are provided. The top plate 9 is located directly above the groove 1.

[0032] During use, the support rod 7 provides rigid support to ensure that the top plate 9 remains stable when the electric cylinder 10 is operated. At the same time, the vertical fixed connection of the support rod 7 ensures that the top plate 9 is always located directly above the groove 1, so that the first drying mechanism 8 can be accurately embedded in the groove 1.

[0033] This utility model also includes a door 3 that is movably connected to one side of the drying oven 2 via a hinge. The door 3 has a slot 11 inside, and there are two slots 11 for two slide rail seats 4 to pass through.

[0034] In use, the door 3 is opened and closed by a hinge, making it easy to open the door 3 and pull out the second drying mechanism 13 during maintenance or cleaning; the slot 11 and the slide rail seat 4 are designed to be inserted into each other, allowing the slide rail seat 4 to be fixedly passed through when the door 3 is closed.

[0035] The present invention also includes a handle 12 fixedly connected to one side of the second drying mechanism 13, and a magnetic block 16 provided at the end of the slider 14 away from the handle 12, wherein the magnetic block 16 is magnetically connected to the inner side of the slide groove 5.

[0036] In use, the handle 12 provides a manual operation point, making it easy for users to pull the second drying mechanism 13 along the slide 5 during maintenance or cleaning; after the second drying mechanism 13 is pushed into place, the magnetic block 16 automatically adheres to one side of the slide 5 to form a magnetic fixation, preventing the mechanism from loosening or shifting during the drying process, and ensuring that the convective hot air from the second drying mechanism 13 and the first drying mechanism 8 acts stably on the car film.

[0037] The present invention also includes air inlets 15 on the outer side of the first drying mechanism 8 and at the bottom of the second drying mechanism 13.

[0038] In use, the air inlet 15 provides an airflow channel for the fans in the first drying unit 8 and the second drying unit 13.

[0039] It should be noted that the working principles of the first drying mechanism 8 and the second drying mechanism 13 can be found in the existing mature technologies mentioned in the background section. The air inlet 15 of the second drying mechanism 13 is not shown in the figure.

[0040] This utility model also includes a feed inlet 6 at one end of the drying box 2.

[0041] In use, the feed port 6 serves as the inlet channel, through which the automotive film to be dried enters the drying chamber 2 for drying.

[0042] In use, the car film to be dried enters the drying chamber 2 through the feed inlet 6. The electric cylinder 10 drives the first drying mechanism 8 to descend and embed itself into the groove 1. At the same time, the second drying mechanism 13 is pushed into the drying chamber 2 along the slide groove 5 on the slide rail seat 4 by the sliders 14 on both sides, so that the magnetic block 16 is attracted and fixed to one side of the slide groove 5. At this time, the first drying mechanism 8 is above the car film and the second drying mechanism 13 is below the car film. Both draw in air through the air inlet 15 and are heated by the electric heating plate inside, forming a uniform hot air flow from top to bottom to dry both sides of the car film. When maintenance or cleaning is required, the electric cylinder 10 lifts the first drying mechanism 8 out of the groove 1 and opens the chamber door 3. The second drying mechanism 13 is pulled out of the drying chamber 2 to the chamber door 3 area along the slide groove 5 by the handle 12, so that all components are fully exposed to the external space for maintenance.
