Description

Technical Field

[0001] This utility model relates to the technical field of wear-resistant coating spraying equipment, specifically to a wear-resistant coating spraying equipment for the surface of plastic products. Background Technology

[0002] Wear-resistant coating spraying equipment for plastic products is a special equipment used to spray wear-resistant coatings onto the surface of plastic products. The coating is atomized and evenly sprayed onto the surface of plastic products through tools such as spray guns to improve their wear resistance, corrosion resistance and decorative properties. This equipment is widely used in the industrial field and can quickly process and form a durable protective layer.

[0003] Plastic products have low hardness and are easily scratched or worn due to friction. By spraying a wear-resistant coating, a protective layer with high hardness and high toughness can be formed on the plastic surface, which significantly improves its wear resistance and scratch resistance. At the same time, the wear-resistant coating can effectively reduce surface damage caused by friction, impact or mechanical stress, thereby extending the service life of plastic products.

[0004] Traditional spray gun spraying methods have many shortcomings when applying wear-resistant coatings to large-area sheet plastics. On the one hand, the spraying range of traditional spray guns is relatively limited, making it difficult to achieve efficient spraying of large-area sheet plastics and ensure uniform coating coverage. On the other hand, traditional spraying methods are difficult to precisely control the spraying area, which can easily lead to ineffective spraying, causing the coating to cover non-target areas and resulting in coating waste. Therefore, a wear-resistant coating spraying device for the surface of plastic products is proposed to address the above problems. Utility Model Content

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-8 This utility model provides a technical solution:

[0030] A wear-resistant coating spraying device for the surface of plastic products includes a support frame 1, an electric telescopic rod 2, and a guide rod 3. A spraying assembly 4 is fixedly connected to the left side of the electric telescopic rod 2, and an adjusting assembly 5 is fixedly connected to the inner side of the spraying assembly 4. The spraying assembly 4 includes a clamping plate 41, a load-bearing ring 43 is fixedly connected to one side of the clamping plate 41, a material collecting seat 44 is fixedly connected to the inner side of the load-bearing ring 43, a nozzle 42 is fixedly connected to the lower end of the material collecting seat 44, and a servo motor 45 is fixedly connected to the top end of the material collecting seat 44. The servo motor 45 has a main shaft. The end is fixedly connected to a folding plate 49. The adjusting component 5 includes a fixed cylinder 51. The fixed cylinder 51 has a movable opening 52 on its inner side. A rubber sealing ring 53 is fixedly connected to the inner side of the movable opening 52. A spring 54 is fixedly connected to the inner side of the fixed cylinder 51. A fixed ring 55 is fixedly connected to the upper end of the spring 54. An extension rod 56 is fixedly connected to the inner side of the fixed ring 55. A rubber plug 57 is fixedly connected to the lower end of the extension rod 56. A ball head 58 is fixedly connected to the top end of the extension rod 56. The outer side of the fixed cylinder 51 is fixedly connected to the inner side of the collecting seat 44.

[0031] As a further implementation of this solution, a reinforcing ring 46 is fixedly connected to the outer side of the folding plate 49, and a caster wheel 47 is fixedly connected to the bottom end of the reinforcing ring 46. The bottom end of the caster wheel 47 is in contact with the upper end of the load-bearing ring 43, and a gap is provided between the bottom end of the folding plate 49 and the upper end of the material collection seat 44. Through the above arrangement, space is provided for the movement of the ball head 58. At the same time, the contact between the caster wheel 47 and the load-bearing ring 43 can provide stable support for the rotation of the folding plate 49, ensuring the stability of the device operation.

[0032] As a further implementation of this solution, a sprayer 48 is fixedly connected to the top of the folding plate 49, and a through hole is opened at the right end of the material collection seat 44. The inner side of the material collection seat 44 is a hollow structure. The outlet of the sprayer 48 is connected to the inner side of the material collection seat 44. The storage tank of the sprayer 48 is inserted between the folding plate 49 and the reinforcing ring 46. Through the above arrangement, the paint can smoothly enter the inner side of the material collection seat 44 from the storage tank of the sprayer 48, and be evenly distributed to each spraying area through the through hole of the material collection seat 44, thereby improving the efficiency and uniformity of paint delivery.

[0033] As a further implementation of this solution, a universal wheel 47 is fixed to the bottom of the clamping plate 41. The bottom of the clamping plate 41 is attached to the upper end of the bracket 1 through the universal wheel 47. The left side of the electric telescopic rod 2 is fixedly connected to the right side of the load-bearing ring 43. A guide rod 3 is fixedly connected to the inner side of the bracket 1. A sliding hole is opened on the inner side of the clamping plate 41. The clamping plate 41 slides on the outside of the guide rod 3 through the sliding hole. Through the above settings, the overall stable connection and support of the device can be achieved, while reducing the resistance when the clamping plate 41 moves, and playing the role of limiting the movement of the clamping plate 41.

[0034] As a further implementation of this solution, the inner side of the material collection seat 44 near the nozzle 42 is provided with a through hole, and the inner side of the material collection seat 44 is connected to the inner side of the nozzle 42. The inner side of the material collection seat 44 near the adjustment component 5 is provided with an installation hole. The number of adjustment components 5 is the same as the number of nozzles 42. The position of the adjustment components 5 is vertically aligned with the position of the nozzles 42. Through the above settings, the paint can smoothly enter the inner side of the nozzle 42 from the inner side of the material collection seat 44 through the through hole. And through the vertical alignment of the adjustment components 5 with the nozzles 42, precise spraying control is achieved, which improves the accuracy and uniformity of spraying.

[0035] As a further implementation of this solution, the upper and lower ends of the extension rod 56 extend out of the outer side of the fixed cylinder 51. The inner side of the rubber sealing ring 53 is in contact with the outer side of the extension rod 56, and the outer side of the fixing ring 55 is in contact with the inner side of the fixed cylinder 51. The extension rod 56 extends out of the upper end of the material collection seat 44, and the ball head 58 is located at the lower end of the folding plate 49. Through the above settings, the extension rod 56 can slide stably within the fixed cylinder 51, and the sealing and guiding functions are achieved through the contact of the rubber sealing ring 53 and the fixing ring 55. At the same time, the cooperation between the ball head 58 and the folding plate 49 can achieve precise adjustment of the spraying range, effectively preventing paint from splashing onto non-target areas and reducing paint waste.

[0036] Workflow: When spraying a wear-resistant coating onto sheet-shaped plastic products, the spraying range is first adjusted according to the size of the plastic sheet. The servo motor 45 is started, causing the folding plate 49 to rotate. The folding plate 49 then rotates the reinforcing ring 46 and the caster 47. The pipe of the spraying machine 48 is a flexible hose, which does not affect the normal rotation of the folding plate 49. The caster 47 rolls on the upper end of the load-bearing ring 43, supporting the folding plate 49 and the reinforcing ring 46. When the folding plate 49 rotates, the end of the folding plate 49 near the adjusting component 5 has a slope, and the top view of the folding plate 49 is an inclined structure. When the folding plate 49 contacts the ball head 58, the ball head 58 moves downwards by the push of the folding plate 49. The ball head 58 drives the fixing ring 55, the extension rod 56, and the rubber plug 57 to move downwards. The fixing ring 55 compresses the spring 54, which resets the fixing ring 55. The extension rod 56 and the fixing ring 55 slide simultaneously on the fixed cylinder. Inside 51, the rubber sealing ring 53 acts as a guide, sealing the space between the fixed cylinder 51 and the extension rod 56. This prevents paint from the inside of the collecting seat 44 from entering the fixed cylinder 51. When the rubber plug 57 moves downward, it enters the nozzle 42, sealing it and adjusting the spraying range of the plastic sheet. When the spraying machine 48 is started, the paint is delivered to the inside of the collecting seat 44, and then enters the unsealed nozzle 42. It is then sprayed out in a mist form from the nozzle 42. The electric telescopic rod 2 is activated to move the spraying assembly 4 and the adjusting assembly 5 left and right, achieving the effect of spraying a corrosion-resistant coating onto the plastic sheet. Based on the above design principle, the device can spray a corrosion-resistant coating onto large-area plastic sheet products. At the same time, the spraying range can be adjusted according to the size of the plastic sheet, avoiding ineffective spraying and reducing paint waste.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
