Description

Technical Field

[0001] This utility model relates to a rubber roller processing equipment, and more particularly to a surface spraying equipment for rubber roller production. Background Technology

[0002] Surface coating is a crucial step in the production of rubber rollers. Traditional rubber roller coating often involves manual operation with handheld spray guns, which has several drawbacks. Firstly, manual coating makes it difficult to ensure the uniformity of the coating on each roller, easily resulting in areas that are too thick or too thin, affecting the consistency of the roller's quality and performance. For example, in the production of some high-precision printing rollers, uneven surface coating can lead to quality problems such as color differences and blurriness in the printed patterns. Secondly, manual coating is inefficient and cannot meet the demands of large-scale industrial production. Especially in large rubber roller manufacturers, where a large number of rollers need to be processed daily, the speed of manual coating cannot keep up with the production pace. Furthermore, manual operation poses certain safety hazards. Long-term exposure of operators to the volatile organic compounds (VOCs) in the coating can harm human health, potentially causing respiratory diseases and skin allergies. Simultaneously, traditional coating equipment has low paint utilization rates; a large amount of paint is scattered into the surrounding environment with the spray gun, not only wasting materials but also increasing production costs and the burden of subsequent environmental remediation.

[0003] Therefore, how to design a surface coating equipment for rubber roller production that can improve the quality of rubber roller surface coating, increase production efficiency, ensure operator safety, and effectively utilize coatings has become a technical problem that the rubber roller manufacturing industry urgently needs to solve. Summary of the Invention

[0004] The purpose of this invention is to provide a surface coating equipment for rubber roller production.

[0005] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0006] This utility model includes a spraying tank assembly, a rubber roller conveying assembly, and a spraying assembly. The rubber roller conveying assembly is arranged on both sides of the spraying tank assembly, and a plurality of rubber rollers to be sprayed are located at the upper end of the spraying tank assembly. The spraying assembly is located inside the spraying tank assembly.

[0007] Furthermore, the spraying tank assembly includes a rubber roller spraying tank and inclined sidewalls of the spraying tank. The inclined sidewalls of the spraying tank are provided on both sides of the rubber roller spraying tank. The upper end of the inclined sidewalls of the spraying tank is an inclined surface. The two mandrels of the rubber roller to be sprayed are located at the upper end of the inclined sidewalls of the spraying tank. The middle section of the rubber roller to be sprayed is located between the two inclined sidewalls of the spraying tank. The spraying assembly is provided below the rubber roller spraying tank. The rubber roller conveying assembly is provided on the outside of the inclined sidewalls of the spraying tank. The driving end of the rubber roller conveying assembly is in contact with the two ends of the mandrels of the rubber roller to be sprayed.

[0008] The rubber roller conveying assembly includes a rubber roller actuating conveyor belt, actuating conveyor belt stops, and a conveyor belt drive motor.

Multiple actuating conveyor belt stops are provided on the outer wall of the rubber roller actuating conveyor belt. The other end of the actuating conveyor belt stops is higher than the upper end of the inclined sidewall of the spraying tank. The drive end of the rubber roller actuating conveyor belt is connected to the drive shaft of the conveyor belt drive motor. One side of the actuating conveyor belt stops can contact one side of the spindle of the rubber roller to be sprayed.

[0009] The spraying assembly includes a top spraying baffle, a spraying circulation pump, and multiple spraying nozzles. The multiple spraying nozzles are connected to the outlet of the spraying circulation pump through pipes. The multiple spraying nozzles are located below the rubber roller spraying groove and face the rubber roller to be sprayed above. The water inlet pipe of the spraying circulation pump is connected to the lower part of the rubber roller spraying groove. The top spraying baffle is located above the rubber roller spraying groove.

[0010] As an improvement, the outlet of the spray tank assembly is also provided with a drying component.

[0011] Specifically, the drying assembly includes a drying tank, a drying tank roller conveyor belt, drying tank conveyor belt actuating blocks, a drying tank electric heating element, and a drying tank blower. The drying tank roller conveyor belt is located on both sides outside the drying tank. There are multiple drying tank conveyor belt actuating blocks, which are evenly distributed on the drying tank roller conveyor belt.

[0013] The beneficial effects of this utility model are:

[0014] This utility model has the following technical effects compared with the prior art:

[0015] High-efficiency spraying: Multiple spray nozzles operate simultaneously, enabling rapid and comprehensive coverage of the roller surface, effectively improving spraying efficiency and meeting the needs of large-scale industrial production. Compared to traditional manual spraying methods, production efficiency is significantly improved, greatly shortening the roller production cycle.

[0016] Uniform spraying: The roller to be sprayed rolls along the inclined side wall under the action of gravity. At the same time, the roller moves the conveyor belt stop at a uniform speed. This dual action ensures that the roller is in a uniform rolling state during the spraying process, so that multiple spray nozzles can evenly spray the paint onto the surface of the roller. This avoids the uneven coating problem that may occur in traditional spraying methods and improves the quality and performance consistency of the roller.

[0017] Paint recycling: The design of the top spray baffle can effectively prevent paint from splashing upwards, allowing excess paint to drip back into the roller spray tank along the baffle, realizing the recycling of paint, reducing paint waste, and lowering production costs.

[0018] High degree of automation: The rubber roller conveying assembly works in conjunction with the spraying assembly and the drying assembly to realize the automated production process of rubber rollers from feeding, spraying, drying to discharge, reducing manual intervention, lowering labor costs, and improving the stability and reliability of the production process.

[0019] Excellent drying effect: The electric heating elements in the drying tank work in conjunction with the air blower to evenly blow heated air onto the surface of the rollers to be dried, accelerating the drying speed of the coating and improving production efficiency. Furthermore, the conveyor belt actuation blocks ensure even transport of the rollers during the drying process, allowing all parts of the rollers to be fully heated and ensuring drying quality.

The spraying assembly is provided at the lower part of the rubber roller spraying tank 1. The rubber roller conveying assembly is provided on the outer side of the spraying tank inclined sidewall 2. The driving end of the rubber roller conveying assembly is in contact with the two ends of the mandrel of the rubber roller 7 to be sprayed.

[0027] The rubber roller conveying assembly includes a rubber roller actuating conveyor belt 3, actuating conveyor belt stops 4, and a conveyor belt drive motor 5. The rubber roller actuating conveyor belt 3 is located outside the inclined side wall 2 of the spraying tank. Multiple actuating conveyor belt stops 4 are provided on the outer wall of the rubber roller actuating conveyor belt 3. The other end of the actuating conveyor belt stops 4 is higher than the upper end of the inclined side wall 2 of the spraying tank. The driving end of the rubber roller actuating conveyor belt 3 is connected to the drive shaft of the conveyor belt drive motor 5. One side of the actuating conveyor belt stops 4 can contact the spindle side of the rubber roller 7 to be sprayed.

[0028] The spraying assembly includes a top spraying baffle 6, a spraying circulation pump 8, and spraying nozzles 9. There are multiple spraying nozzles 9, and the multiple spraying nozzles 9 are connected to the outlet of the spraying circulation pump 8 through pipes.

[0029] As an improvement, the outlet of the spray tank assembly is also provided with a drying component.

[0030] Specifically, the drying assembly includes a drying trough 10, a drying trough rubber roller conveyor belt 11, a drying trough conveyor belt actuating blocks 12, a drying trough electric heating element 13, and a drying trough blower 14. The drying trough rubber roller conveyor belt 11 is disposed on both sides outside the drying trough 10. There are multiple drying trough conveyor belt actuating blocks 12, which are evenly distributed on the drying trough rubber roller conveyor belt 11. The height of the drying trough conveyor belt actuating blocks 12 is higher than the top of the drying trough 10. One side of the drying trough conveyor belt actuating blocks 12 can contact the mandrel side of the rubber roller 7 to be sprayed.

[0032] The working principle of this utility model is as follows:

[0033] In use, the roller 7 to be sprayed is placed on the upper feed side of the inclined sidewall 2 of the spraying tank via the discharge conveyor of the previous processing equipment. The inclined surface of the feed side is higher than that of the discharge side. Under the action of gravity, the roller 7 will roll along the inclined sidewall 2 of the spraying tank. As the roller 7 rolls, the spraying circulation pump 8 draws the spraying liquid from the lower end of the roller spraying tank 1 and sprays it upward through the spray nozzle 9. Due to the multiple nozzles, the surface of the roller 7 is evenly sprayed while it rolls naturally. To ensure that multiple rollers 7 roll evenly and simultaneously without contact between them, the conveyor belt drive motor 5 drives the roller-driven conveyor belt 3 to rotate. Multiple conveyor belt stops 4 are provided on the conveyor belt 3 to prevent the roller 7 from rolling at a uniform speed. The moving conveyor belt stops 4 allow multiple rubber rollers 7 to be sprayed to maintain a uniform interval while rolling, and to roll. Excess spray liquid is sprayed onto the top of the top spray baffle 6 and drips into the rubber roller spraying trough 1 for reuse. After being discharged from the discharge side of the rubber roller spraying trough 1, the rubber rollers 7 fall into the upper end of the drying trough 10. Similarly, the drying trough rubber roller conveyor belt 11 drives the drying trough conveyor belt actuating block 12 to actuate the rubber rollers 7 to be sprayed evenly on the drying trough 10. The drying trough rubber roller conveyor belt 11 is synchronously connected with the rubber roller actuating conveyor belt 3. The drying trough electric heating element 13 heats the rubber rollers. The drying trough blower 14 delivers air to the area below the drying trough electric heating element 13. After being heated by the drying trough electric heating element 13, the air heats and dries the rubber rollers 7 above the drying trough 10. Finally, the rubber rollers are discharged through the rubber roller discharge rack 15 and enter the next process or end the process.
