Description

Technical Field

[0001] This utility model relates to the field of workpiece coating processing technology, and in particular to a coating machine anti-splash mechanism. Background Technology

[0002] Coating machines mainly use spraying, roller coating, scraping, and curtain coating methods. Roller coating machines, also known as roller coaters, can coat plates and fabrics. The object to be coated passes under the rollers as they are conveyed by rollers, and the rollers drive the rollers to rotate, ensuring that the coating covers the object completely and spreads it evenly, preventing drips on the workpiece surface.

[0003] When a roller coater is used to coat objects, paint splattering can occur if the paint viscosity and the rotation speed of the roller are mismatched. To solve this problem, a protective cover is added to the outside of the roller to cover it and prevent paint from splashing onto other parts and affecting the coating effect. However, during long-term roller coating, the paint splashed onto the protective cover will accumulate and form a drip phenomenon, eventually dripping onto the fabric or board and affecting the coating effect of the fabric or board. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a paint anti-splatter mechanism for a coating machine to solve the problem that paint on the protective cover will accumulate and form drips, eventually falling onto the fabric or board and affecting the coating effect of the fabric or board.

[0005] Based on the above objectives, this utility model provides a paint splash prevention mechanism for a coating machine, including a protective cover. The anti-splash mechanism also includes ventilation grooves respectively disposed on both sides of the protective cover. Several inclined baffles are fixedly disposed in the ventilation grooves, and ventilation channels are formed between two adjacent inclined baffles. The inclined baffles are used to intercept splashed paint.

[0006] The two material collection channels located at the bottom of the protective cover are used to collect the paint dripping from the inclined baffle. The bottom of the material collection channels is provided with a protective air duct facing the inside of the protective cover.

[0007] The air supply section is used to deliver airflow to the protective air duct, so that the airflow blows the paint splashed towards the aggregate chute onto the inclined baffle.

[0008] A cleaning section is provided in the ventilation slot, which is used to scrape off the paint splashed onto the surface of the inclined baffle.

[0009] A drive unit used to drive the two cleaning sections to move linearly back and forth.

[0010] Preferably, the inclined baffles are inclined from the inside of the protective cover to the outside, and several inclined baffles are arranged vertically side by side inside the ventilation slot.

[0011] Preferably, the cleaning part includes a nut sleeve and a scraper that is slidably disposed inside the ventilation groove.

[0012] A connecting frame is fixedly disposed between several scraper blades, and the connecting frame is fixedly disposed on a nut sleeve.

[0013] Preferably, the connecting frame is located between the nut sleeve and the scraper, and the top and bottom of the scraper contact the opposite surfaces of two adjacent inclined baffles, respectively.

[0014] Preferably, the material collection chute is located on the long side of the bottom of the protective cover, and the inclined baffle is located within the horizontal range of the material collection chute in the horizontal direction.

[0015] Preferably, the ventilation groove is located on the long side vertical surface of the protective cover, and the bottom of the ventilation groove is connected to the interior of the material collection chute.

[0016] Preferably, the drive unit includes horizontal supports that are fixed to both ends of the protective cover. One of the horizontal supports is rotatably provided with a double drive wheel and a servo motor for driving the double drive wheel to rotate. A reciprocating screw is rotatably provided between the two horizontal supports. A driven wheel is fixed to one end of the reciprocating screw. Belts are respectively rotatably sleeved between the double drive wheel and the two driven wheels.

[0017] Preferably, the two driven wheels are staggered in the axial direction of the reciprocating screw, and the nut sleeve is slidably sleeved on the reciprocating screw.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes a combination of a material collection chute, several inclined baffles, and a protective air duct at the bottom of the protective cover. This allows paint dripping from the inner wall of the protective cover to flow into the material collection chute, preventing paint from dripping onto the workpiece and affecting the uniformity of the coating distribution and the aesthetic appearance of the workpiece. A high-speed airflow is delivered into the protective air duct by a fan and directed towards the bottom of the protective cover, effectively preventing paint from splashing onto the bottom of the material collection chute. The upward-blowing airflow also carries some of the splashed paint towards the ventilation groove, causing it to collect outside the inclined baffles. A drive unit then drives a scraper to reciprocate linearly, scraping away the paint from the surface of the inclined baffles. The paint collects into a flowable liquid and flows into the material collection chute for final collection, facilitating subsequent centralized cleaning. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] like Figures 1 to 4 As shown, a coating machine's anti-splash mechanism includes a protective cover 1. The anti-splash mechanism also includes ventilation channels 2 respectively disposed on both sides of the protective cover 1. Several inclined baffles 3 are fixedly disposed in the ventilation channels 2. A ventilation groove 4 is formed between two adjacent inclined baffles 3. The inclined baffles 3 are used to intercept splashed coating. After the coating on the inclined baffles 3 accumulates to a certain amount, the coating will slide down the surface of the inclined baffles 3 to the outside of the protective cover 1, preventing excess coating on the inclined baffles 3 from falling onto the workpiece to be coated and affecting the uniformity of the coating sprayed on the workpiece surface.

[0030] The two material collection channels 6 located at the bottom of the protective cover 1 are used to collect the paint dripping from the inclined baffle 3. The bottom of the material collection channel 6 is provided with a protective air duct 9 facing the inside of the protective cover 1.

[0031] The air supply unit 8 is used to deliver airflow to the protective air duct 9. The air supply unit 8 includes an air compressor and an air supply duct connecting the output end of the air compressor and the protective air duct 9, so that the airflow blows the paint splashed onto the collection slide 6 onto the inclined baffle 3, further improving the shielding and collection of the splashed paint, and avoiding affecting the uniformity of the coating thickness on the workpiece.

[0032] The cleaning section 5 is located in the ventilation slot 2 and is used to scrape off the paint that splashes onto the surface of the inclined baffle 3.

[0033] The drive unit 7, which drives the two cleaning units 5 to move linearly back and forth, allows the paint adhering to the surface of the inclined baffle 3 to converge and slide down the surface of the inclined baffle 3 into the collection chute 6 under the cleaning of the reciprocating cleaning units 5, thus completing the centralized collection of waste paint and facilitating subsequent centralized cleaning.

[0034] like Figures 1 to 4 As shown, the inclined baffle 3 is inclined from the inside of the protective cover 1 to the outside, and several inclined baffles 3 are arranged vertically side by side inside the ventilation channel 2. This design allows the waste paint falling on the surface of the inclined baffle 3 to gather into flowable paint droplets, which can then slide into the collection channel 6, thus successfully collecting the waste paint. This prevents the waste paint from falling onto the workpiece during the spraying process, which would affect the uniformity of the coating thickness on the workpiece surface. It also allows for the complete blocking and collection of splashed paint, preventing the waste paint from splashing onto other items outside the protective cover 1.

[0035] like Figures 2 to 4 As shown, the cleaning part 5 includes a nut sleeve 51 and a scraper 53 that is slidably disposed inside the ventilation groove 4.

[0036] A connecting frame 52 is fixedly disposed between several scraper blades 53, and the connecting frame 52 is fixedly disposed on the nut sleeve 51.

[0037] The connecting frame 52 is located between the nut sleeve 51 and the scraper 53. The top and bottom of the scraper 53 respectively contact the opposite surfaces of two adjacent inclined baffles 3. This design allows the scraper 53 to completely scrape off the waste paint splashed onto both sides of the inclined baffles 3 when scraping the waste paint on the surface of the inclined baffles 3, and to collect the waste paint in the collection chute 6 for easy subsequent cleaning.

[0038] like Figures 1 to 4 As shown, the aggregate chute 6 is located on the long side of the bottom of the protective cover 1, and the inclined baffle 3 is located within the horizontal range of the aggregate chute 6 in the horizontal direction.

[0039] The ventilation duct 2 is located on the long vertical surface of the protective cover 1, and the bottom of the ventilation duct 2 is connected to the interior of the material collection channel 6. This design allows most of the splashed waste paint during the spraying process to fall between the inclined baffles 3 with the airflow blown out of the protective air duct 9, and to impact the surface of the inclined baffles 3 with the airflow. As the spraying time increases, the waste paint splashed on the inclined baffles 3 will gradually accumulate to a flowable state, and can then automatically flow along the surface of the inclined baffles 3 to the interior of the material collection channel 6, completing the collection of waste paint and facilitating subsequent cleaning.

[0040] like Figure 3 and Figure 4 As shown, the drive unit 7 includes a horizontal support 71 that is fixed to both ends of the protective cover 1. A double drive wheel 73 is rotatably mounted on one of the horizontal supports 71. A servo motor 72 is used to drive the double drive wheel 73 to rotate. A reciprocating screw 74 is rotatably mounted between the two horizontal supports 71. A driven wheel 75 is fixedly mounted on one end of the reciprocating screw 74. A belt 76 is rotatably mounted between the double drive wheel 73 and the two driven wheels 75.

[0041] Two driven wheels 75 are offset along the axial direction of the reciprocating screw 74, and the nut sleeve 51 is slidably sleeved on the reciprocating screw 74. The servo motor 72 drives the double drive wheels 73 to rotate, and the power can be transmitted through the belt 76 and the driven wheels 75 to drive the reciprocating screw 74 to rotate. The rotating reciprocating screw 74 drives the nut sleeve 51 to move back and forth linearly along the axial direction of the reciprocating screw 74. The nut sleeve 51 drives the connecting frame 52 and several scrapers 53 to move linearly in sync, which can remove the paint on the surface of the inclined baffle 3 in a timely manner, and avoid excessive paint accumulation and solidification on the surface of the inclined baffle 3, which would affect cleaning.

[0042] Working principle: The air supply unit 8 delivers airflow into the protective air duct 9, causing the airflow to blow out from inside the protective air duct 9. This creates an airflow wall between the bottom of the collecting chute 6 and the inside of the protective cover 1, preventing paint from splashing onto the bottom of the collecting chute 6. The blown airflow also blows the splashed paint between two adjacent inclined baffles 3, where it impacts the surface of the inclined baffles 3, allowing the inclined baffles 3 to successfully intercept the splashed paint and prevent it from splashing onto other items outside the protective cover 1, thus reducing the workload of subsequent cleaning. At the same time, the servo motor 72 is started, driving the double drive wheel 73 to rotate. Through the power transmission of the belt 76 and the driven wheel 75, the reciprocating screw 74 is driven to rotate. The rotating reciprocating screw 74 drives the nut sleeve 51 to move reciprocally in a straight line along the axial direction of the reciprocating screw 74. The nut sleeve 51 drives the connecting frame 52 and several scraper blades 53 to move in a straight line synchronously, which can scrape off the paint on the surface of the inclined baffles 3 in a timely manner, preventing excessive paint accumulation and hardening on the surface of the inclined baffles 3, which would affect cleaning.
