A glass film spraying equipment

Abstract

This utility model discloses a glass film spraying device, belonging to the technical field of spraying equipment. It includes a roller conveyor, which comprises a drive frame with several arrayed rollers installed between the drive frame members; anti-slip sleeves fitted over the rollers; a spraying frame spanning the middle of the roller conveyor; and a guide plate seat mounted on the drive frame, on which a slidingly connected anti-deviation frame is installed. The anti-deviation frame includes several roller limiting units. Its key technical features are: the structure in direct contact with the glass plate within the roller limiting unit is a rolling roller, and its contact with the glass plate is line contact, thus adapting to glass plates of different sizes and preventing damage to the glass plate during spacing adjustments.

Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a glass film spraying equipment. Background Technology

[0002] Window film spraying is a process that involves uniformly spraying a specific coating onto the glass surface. Specialized equipment is used during the process to ensure precise coating adhesion. The resulting window film offers significant benefits: it effectively blocks ultraviolet rays, protecting occupants and items from harmful UV radiation; it also enhances the glass's thermal insulation, reducing indoor temperature fluctuations and saving energy; it improves privacy, making it difficult to see inside from the outside; and it increases the glass's strength, providing cushioning against impacts and reducing the risk of breakage, thus ensuring safety.

[0003] The utility model with announcement number CN219950848U discloses a glass coating spraying machine. When the glass is being transported, the electric telescopic rod drives the push plate to move laterally until the push plate contacts both sides of the glass. As the glass moves with the conveyor belt, the glass will cause the balls to roll in the groove due to friction. In this way, the glass can be limited without affecting the movement of the glass, and the position of the glass will be avoided during the transport process.

[0004] While the aforementioned spraying machine can limit the movement of the glass plate by using ball bearings to hold it against both sides, the contact between the ball bearings and the glass plate can be considered point contact. Based on this contact method, there are matching requirements between the height of the ball bearings and the thickness of the glass plate. When the glass plate is thin, its side cannot make direct contact with the ball bearings. In this case, the ball bearings contact the upper edge of the glass plate, which can easily cause the glass plate to break at the corners under pressure. When the glass plate is thick, since the ball bearings can roll freely 360 degrees, the glass plate may be warped by the ball bearings squeezing and rolling when the push plate moves inward, affecting its normal placement. In addition, the aforementioned spraying machine uses a conveyor belt to transport the glass plate. During the spraying process, the surface of the conveyor belt will inevitably be contaminated with liquid paint. After long-term use, a layer of paint will be separated between the conveyor belt and the glass plate, resulting in insufficient friction between the conveyor belt and the glass plate, causing slippage when transporting the glass plate. Therefore, to address the above problems, a glass film spraying device is proposed. Utility Model Content

[0005] To address the technical problems in comparative technologies, such as the ball bearing limiting method easily causing damage to the glass plate and failing to restrain the glass plate from tilting, and the conveyor belt method easily causing slippage due to paint accumulation, this utility model provides a glass film spraying device.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A glass film spraying device includes a roller conveyor, which includes a drive frame with a plurality of rollers arranged in an array between the drive frame; an anti-slip sleeve fitted over the rollers; a spraying frame spanning the middle of the roller conveyor; a guide plate seat mounted on the drive frame, on which a slidingly connected anti-deviation frame is mounted; and a spacing adjustment mechanism for driving the anti-deviation frame to slide inward and outward; wherein the anti-deviation frame includes a plurality of roller limiting units slidably connected to the guide plate seat, which are disposed between the rollers, and the ends of the roller limiting units are connected as one unit by connecting plates.

[0008] In one possible implementation, a guide cylinder is fixedly mounted on the guide plate seat; the roller limiting unit includes a slide rod slidably mounted in the guide cylinder, with a shaft core installed at its end, and a rotating roller cylinder mounted outside the shaft core.

[0009] In one possible implementation, the horizontal plane at the bottom of the rolling cylinder is lower than the horizontal plane at the highest point of the anti-slip sleeve.

[0010] In one possible implementation, the anti-slip sleeve includes a base cylinder with a plurality of slots arranged in a circumferential array on its inner wall, and a plurality of locking ridges corresponding to the slots are fixedly provided on the outer wall of the rolling shaft, with the slots and locking ridges engaging and connecting.

[0011] In one possible implementation, a plurality of friction ridges arranged in a circumferential array are fixedly provided on the base cylinder, and a drainage groove is formed between adjacent friction ridges.

[0012] In one possible implementation, the outer end face of the friction ridge is provided with a plurality of anti-slip grooves arranged in a circumferential array, the length of the anti-slip grooves being consistent with the length of the friction ridge.

[0013] In one possible implementation, the spacing adjustment mechanism includes a mounting bracket installed on a spraying rack, with electric push rods installed at both ends, the ends of which are fixedly connected to a connecting plate.

[0014] In one possible implementation, the spray frame includes a gantry on which a centrally located spraying mechanism is mounted.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The anti-deviation frame consists of several roller limiting units, which are slidably connected to the guide plate seat. The distance between the roller limiting units on both sides can be adjusted by sliding to accommodate glass plates of different sizes. Since the structure in the roller limiting unit that directly contacts the glass plate is a rolling cylinder, the contact method between the cylinder and the glass plate is line contact. Therefore, it can accommodate glass plates of different sizes and will not damage the glass plate during the adjustment of the distance. At the same time, since the rolling cylinder can only rotate around the axis, and the glass plate needs to slide and rub against it during the flipping and tilting process, the rolling cylinder can restrain the glass plate to prevent it from sliding and tilting.

[0017] Because the roller conveyor transports the glass plate placed on it through multiple rollers with gaps between them, excess paint will fall through the gaps during spraying, preventing excessive accumulation and thus reducing the likelihood of slippage. Furthermore, the rollers are fitted with anti-slip sleeves, and the base of the anti-slip sleeve has several friction ridges. The drainage channels formed between these ridges can discharge the liquid paint adhering to the surface during the rotation of the base sleeve, while simultaneously preventing the formation of a liquid film on the surface of the anti-slip sleeve. This significantly enhances the friction between the anti-slip sleeve and the glass plate. Attached Figure Description

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 As shown, this embodiment provides a glass film spraying device, including a roller conveyor 1, which includes a drive frame 11, with a plurality of rollers 12 arranged in an array between the drive frame 11; an anti-slip sleeve 2, which is sleeved on the outside of the rollers 12; a spraying frame 3, which is arranged across the middle of the roller conveyor 1; a guide plate seat 4, which is mounted on the drive frame 11, and a slidingly connected anti-deviation frame 5 is mounted on it; and a spacing adjustment mechanism 6, which is used to drive the anti-deviation frame 5 to slide inward and outward.

[0026] With the above-described structure, during operation, the roller conveyor 1 drives the roller shaft 12 to rotate, which in turn drives the glass plate placed on it to move forward through friction. The glass plate passes through the spraying frame 3, which works continuously during this process to complete the spraying work on the entire glass plate. Before the roller conveyor 1 starts working, when the glass plate is placed on it, the anti-deviation frame 5 needs to be slid by the spacing adjustment mechanism 6 to fit against both sides of the glass plate to limit its movement. This ensures that the glass plate does not deviate or rotate during its forward movement, thus ensuring the smooth progress of the spraying work.

[0027] The anti-deviation frame 5 includes several roller limiting units 51 slidably connected to the guide plate seat 4, which are arranged between the rolling shafts 12. The ends of the roller limiting units 51 are connected as one unit by a connecting plate 52. The spacing adjustment mechanism 6 includes a mounting bracket 61 installed on the spraying frame 3, with electric push rods 62 installed at both ends. The ends of the electric push rods 62 are fixedly connected to the connecting plate 52. Figure 2 - Figure 3 As shown, when the size of the glass plate to be transported changes, the electric push rod 62 pulls the connecting plate 52 to move the several roller limiting units 51 installed on it outward, which facilitates the placement of the glass plate. After the glass plate is placed, the electric push rod 62 pushes the roller limiting units 51 inward through the connecting plate 52 to make them fit against the two sides of the glass plate, ensuring the effectiveness of the limiting effect.

[0028] like Figure 3As shown, a guide cylinder 41 is fixedly installed on the guide plate seat 4; the roller limiting unit 51 includes a slide rod 511 slidably installed in the guide cylinder 41, with a shaft core 512 installed at its end, and a rotating roller cylinder 513 installed outside the shaft core 512. In particular, the horizontal plane where the bottom end of the roller cylinder 513 is located is lower than the horizontal plane where the highest point of the anti-slip sleeve 2 is located. Since the structure in the roller limiting unit 51 that directly contacts the glass plate is the rolling roller cylinder 513, its contact with the glass plate is a line contact. Therefore, it can adapt to glass plates of different sizes and will not cause damage to the glass plate during the adjustment of the spacing. At the same time, since the roller cylinder 513 can only rotate around the axis, and the glass plate needs to slide and rub against it during the flipping and tilting process, the roller cylinder 513 can constrain the glass plate so that it does not slide and tilt.

[0029] like Figure 4 As shown, the anti-slip sleeve 2 includes a base cylinder 21, on which a plurality of friction ridges 22 arranged in a circumferential array are fixedly provided. A drain groove 23 is formed between adjacent friction ridges 22. The drain groove 23 can drain the liquid coating adhering to the surface during the rotation of the base cylinder 21, and at the same time prevent the formation of a liquid film on the surface of the anti-slip sleeve 2, thereby significantly enhancing the friction between it and the glass plate. In addition, a plurality of anti-slip grooves 221 arranged in a circumferential array are provided on the outer end face of the friction ridges 22. The length of the anti-slip grooves 221 is the same as the length of the friction ridges 22. The above structure can significantly improve the friction between the friction ridges 22 and the glass plate, and the anti-slip grooves 221 can also prevent the formation of a liquid film on the surface of the friction ridges 22, thus avoiding slippage.

[0030] The inner wall of the base cylinder 21 is provided with a number of slots 211 arranged in a circular array, and the outer wall of the rolling shaft 12 is fixedly provided with a number of ridges 121 corresponding to the slots 211. The slots 211 and the ridges 121 are engaged and connected. The above structure can realize the detachable connection between the anti-slip sleeve 2 and the rolling shaft 12, thereby facilitating the disassembly, cleaning or replacement of the anti-slip sleeve 2.

[0031] like Figure 2 As shown, the spraying frame 3 includes a gantry 31 on which a centrally arranged spraying mechanism 32 is installed. The spraying mechanism 32 can spray atomized paint to form a film layer on the glass plate surface. The structure and working principle of the spraying mechanism 32 are the same as those of the sprayer in the announcement number CN219950848U.

[0032] The working principle and usage process of this utility model:

[0033] When placing the glass plate on it, the anti-deviation frame 5 is driven to slide by the spacing adjustment mechanism 6 to fit against the sides of the glass plate and play a limiting role, thereby ensuring that the glass plate does not deviate or rotate during its forward movement and ensuring the smooth progress of the spraying work. Specifically, when the size of the glass plate to be transported changes, the electric push rod 62 pulls the connecting plate 52 to move several roller limiting units 51 installed on it outward, which facilitates the placement of the glass plate. After the glass plate is placed, the electric push rod 62 pushes the roller limiting units 51 inward through the connecting plate 52 to fit against the sides of the glass plate, ensuring the effectiveness of the limiting effect.

[0034] Subsequently, the roller conveyor 1 drives the roller shaft 12 to rotate, which in turn drives the glass plate placed on it to move forward through friction, and through the spraying frame 3. During this process, the spraying frame 3 works continuously to complete the spraying work on the entire glass plate.

[0035] To prevent slippage during transport, an anti-slip sleeve 2 is provided on the outer sleeve of the rolling shaft 12. The base cylinder 21 of the anti-slip sleeve 2 is provided with several friction ridges 22. The drainage grooves 23 formed therebetween can discharge the liquid coating adhering to the surface during the rotation of the base cylinder 21, while preventing the formation of a liquid film on the surface of the anti-slip sleeve 2, thereby significantly enhancing the friction between it and the glass plate.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
