Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of spraying equipment. Specifically, this utility model relates to a paint spraying line anti-fouling connecting rod shielding device. Background Technology
[0002] During the painting process, most manufacturers currently produce small batches of multiple varieties of paint and customized colors, which means that the paint color needs to be changed multiple times a day. At present, all manufacturers adopt the method of scheduling the same color together and leaving one or two workstations empty in between when changing paint colors. If the workstation is not empty, the paint of the previous workstation will be contaminated.
[0003] However, existing antifouling paint methods have the following drawbacks:
[0004] 1. Low workstation utilization: Empty workstations result in the incomplete utilization of workstations on the production line, reducing overall production efficiency.
[0005] 2. Paint staining issue still exists: Even if the workstation is empty, a small amount of paint will still contaminate the subsequent parts, affecting product quality.
[0006] 3. Increased costs: The problem of stained paint not only increases production and manufacturing costs, but also leads to higher rework costs, while wasting a lot of human and material resources. Utility Model Content
[0007] This utility model provides a paint-contamination-proof connecting rod shielding device for paint spraying lines, which solves the problems mentioned in the background art.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a paint spraying line anti-fouling connecting rod shielding device, including a fixed frame, a bellows protective cover installed at the rear end of the fixed frame, a drive component installed on the fixed frame, and a shielding component connected to the drive component.
[0009] Preferably, the drive assembly includes a servo motor mounted on one side of the fixed frame, a drive bevel gear connected to the output shaft of the servo motor, and a transmission bevel gear adapted to the drive bevel gear.
[0010] Preferably, the blocking component includes a blocking unit, and the blocking unit is provided in several groups. The first group of blocking units is connected to the transmission bevel gear, and every two groups of blocking units are connected by a gear set. Each gear set is provided with a connecting rod arm.
[0011] Preferably, each pair of the connecting arms is rotatably connected by an unfolding connecting rod, and the gear set consists of two meshing spur gears.
[0012] Preferably, the blocking unit consists of two sets of protective fixed crossbars, two sets of protective fixed connecting rods, and a shielding cloth.
[0013] The beneficial effects of adopting the above technical solutions are:
[0014] I. This solution, by deploying the shielding components, confines the paint to a specific area, effectively isolating the front and rear workstations, preventing paint drift and resulting paint contamination, greatly improving the first-time coating pass rate, and ensuring that the product surface coating is uniform, beautiful, and flawless.
[0015] Second, this solution does not require any empty workstations, and can make full use of all workstations on the production line, ensuring efficient operation of each workstation and greatly improving production efficiency. It is especially suitable for small-batch, multi-variety spraying scenarios.
[0016] Third, by effectively solving the problem of paint contamination, this solution reduces the number of reworks required due to paint contamination on the products, avoids the waste of human and material resources caused by paint contamination, improves resource utilization efficiency, and further reduces production costs.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.
[0025] Specifically, such as Figures 1 to 5 As shown, a paint spraying line anti-fouling linkage shielding device includes a fixed frame 1, a bellows protective cover 2 installed at the rear end of the fixed frame 1, a drive assembly 3 installed on the fixed frame 1, and a shielding assembly 4 connected to the drive assembly 3.
[0026] It should be noted that this solution effectively isolates the front and rear workstations by unfolding the shielding component 4, preventing paint drift and ensuring the quality of product spraying.
[0027] The drive assembly 3 includes a servo motor 31 mounted on one side of the fixed frame 1, a drive bevel gear 32 connected to the output shaft of the servo motor 31, and a transmission bevel gear 33 adapted to the drive bevel gear 32.
[0028] It should be noted that after the servo motor 31 starts, it drives the drive bevel gear 32 to rotate, and then transmits the power to the shielding component 4 through the transmission bevel gear 33.
[0029] The blocking component 4 includes a blocking unit 41, and the blocking unit 41 is provided in several groups. The first group of blocking units 41 is connected to the transmission bevel gear 33. Every two groups of blocking units 41 are connected by a gear set 42. Each gear set 42 is provided with a connecting rod arm 43.
[0030] Each pair of connecting arms 43 is rotatably connected by an unfolding connecting rod 44, and the gear set 42 consists of two meshing spur gears.
[0031] The blocking unit 41 consists of two sets of protective fixed crossbars, two sets of protective fixed connecting rods, and a shielding cloth.
[0032] It should be noted that when the transmission bevel gear 33 rotates, it drives the first set of blocking units 41 connected to it to move. Through the transmission of the gear set 42, each blocking unit 41 moves in sequence. Through the linkage of the connecting arm 43 and the unfolding connecting rod 44, the shielding assembly 4 is unfolded and closed. The shielding cloth plays the role of preventing paint from splashing.
[0033] The specific working method is described below using specific embodiments: Example 1:
[0034] Assuming this device is installed on a paint spraying line, the mounting bracket 1 is securely installed at a suitable location near the spraying station, providing stable support for the entire device. When a paint color change is required, the servo motor 31 is activated, driving the drive bevel gear 32 to rotate. The drive bevel gear 32 interacts with the transmission bevel gear 33, transmitting power to the first set of blocking units 41 connected to the transmission bevel gear 33. The first set of blocking units 41 drives the next set of blocking units 41 through the gear set 42. During this process, the connecting arm 43 and the unfolding connecting rod 44 work together to gradually unfold the shielding component 4. As the shielding component 4 unfolds, the shielding cloth on the blocking unit 41 is fully unfolded, forming an effective shielding barrier to prevent paint from splashing from the spraying station to subsequent stations, thereby avoiding contamination of the components at subsequent stations. Example 2:
[0035] When the painting process is completed and the masking device needs to be retracted, the servo motor 31 reverses, driving the bevel gear 32 to rotate in the opposite direction, which in turn drives the transmission bevel gear 33 to rotate in the opposite direction. This causes the blocking units 41 of the masking assembly 4 to gradually close under the coordinated action of the gear set 42, the connecting arm 43 and the unfolding connecting rod 44. Finally, the masking assembly 4 returns to the closed state, without affecting the normal operation of the painting line, and at the same time preparing for the next anti-fouling operation. Throughout the process, the accordion cover 2 protects the relevant components at the rear end of the fixing frame 1 and prevents paint from seeping in.
[0036] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
