DETAILED DESCRIPTION

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] As used herein, the terms “parallel,” “perpendicular,” etc., are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0023] The technical solution provided by this utility model is as follows: Figure 1 , 2 As shown in Figure 3, an additive coating device for producing washing machine lids includes a frame 10. A roller conveying mechanism is mounted on the frame 10 for horizontally conveying a circular metal plate 00 for processing the lid. An additive distribution mechanism is located above the conveying path of the roller conveying mechanism. The additive distribution mechanism applies the additive to the upper surface of the circular metal plate 00 using a roller brush. Using a roller brush to apply the additive ensures a uniform additive layer on the surface of the circular metal plate 00, and the amount of additive applied can be well controlled, facilitating subsequent transfer of the circular metal plate 00 and avoiding the negative impact of excessive coating on subsequent processes.

[0024] A further embodiment is as follows: The additive distribution mechanism includes an additive distribution roller 30 located on the upper side of the roller conveying mechanism. The additive distribution roller 30 is rotatably mounted on the frame 10. The length direction of the additive distribution roller 30 matches the length direction of the conveying roller 11 on the roller conveying mechanism. The outer surface layer of the coating conveying roller is composed of a liquid storage material capable of absorbing additives. When implemented in this way, as the circular metal plate 00 passes under it, the liquid storage material is squeezed, causing the additives inside to seep out, thereby uniformly coating the upper surface of the circular metal plate 00 passing under it, improving the uniformity and efficiency of additive coating on the circular metal plate. The additive distribution roller 30 can be connected to a drive mechanism that adjusts its rotation. A replenishment mechanism is also included, which is used to replenish the additives to the outer surface layer of the additive distribution roller 30. Since the amount of additive adsorbed on the additive distribution roller 30 will decrease after the additive is coated, in order to achieve continuous production, it is necessary to continuously replenish the additive to the additive distribution roller 30 through a set replenishment mechanism to ensure the reliability and continuity of production.

[0025] The detailed operation is: further comprising a storage rack 22 for stacking and storing the circular metal plates, a feeding mechanism is arranged between the storage rack 22 and the feeding end of the roller conveying mechanism for transferring the circular metal plates 00. The feeding mechanism comprises a feeding rack 21 arranged on the upper side of the roller conveying mechanism, the feeding rack 21 is provided with a feeding mounting seat 23 slidingly installed along the length direction of the conveying roller 11, and the feeding mounting seat 23 is provided with a feeding grabbing mechanism for grabbing the circular metal plates 00. The feeding grabbing mechanism comprises a feeding grabbing mounting frame which is liftably installed on the feeding mounting seat 23, and the feeding grabbing mounting frame is provided with feeding grabbing suction cups 24 arranged in a suspended stand shape, and the feeding grabbing suction cups 24 are used for adsorbing and grabbing the circular metal plates 00. In the specific operation, the feeding grabbing mounting frame can also be arranged as an upper feeding mounting frame and a lower feeding mounting frame, the lower feeding mounting frame is movably installed on the upper feeding mounting frame in the horizontal direction, the horizontal direction here can be one horizontal direction or multiple horizontal directions, the upper feeding mounting frame is movably installed on the feeding grabbing mounting seat in the vertical direction, the feeding grabbing suction cups 24 are installed on the lower feeding mounting frame, and the movement of the feeding grabbing mounting seat, the upper feeding mounting frame and the lower feeding mounting frame is adjusted through the feeding adjusting assembly, so as to meet different material taking requirements. The storage racks 22 are arranged on both outer sides of the roller conveying mechanism. Such arrangement can avoid the situation that the equipment needs to be stopped for loading the circular metal plates after the material taking is completed, and ensures the reliability of the equipment operation.

[0026] Further scheme is that the discharging end of the roller conveying mechanism is provided with a limiting mechanism for limiting the movement of the round metal plate 00 after the uniform distribution of the auxiliary agent, and a material transfer mechanism for transferring the round metal plate 00 limited to the next process for other processing. The limiting mechanism is provided to ensure the reliability of the material taking of the material transfer mechanism, so that the position of the round metal plate 00 passing each time is consistent, thereby realizing reliable material transfer to the subsequent process. The material transfer mechanism can be a material transfer robot, and a material transfer grabbing mechanism consistent with the feeding grabbing mounting rack structure is arranged on the mechanical arm of the material transfer robot. Of course, it can also be implemented in a manner consistent with the feeding mechanism, and the specific selection is made according to the actual situation. The roller conveying mechanism includes conveying rollers 11 arranged at intervals, the limiting mechanism includes a limiting mounting block arranged corresponding to the middle part of the conveying roller 11, a limiting magnet 12 is mounted on the limiting mounting block, the height of the limiting magnet 12 is greater than the height of the round metal plate 00 when conveying on the roller conveying line, and the limiting magnet 12 adsorbs the abutting edge of the round metal plate 00 abutting against the limiting mounting block and makes it uplift. Since the metal plate for producing the cover plate is a round metal plate 00, the round metal plate 00 is hindered when moving to the discharging end, and due to the driving action of the roller conveying line, the round metal plate 00 will move along the width direction of the roller conveying line, resulting in inaccurate positioning and affecting the subsequent material transfer processing. At the same time, different sizes of round metal plates 00 need to use different types or structures of limiting mechanisms for limiting. By using the limiting magnet 12 arranged, after the round metal plate 00 moves to the position, the adsorption action of the limiting magnet 12 makes the abutting edge of the round metal plate 00 uplift at a small angle, so that the driving force between the round metal plate 00 and the roller conveying mechanism is weakened, and the resistance of the round metal plate 00 moving along the length direction of the conveying roller 11 is increased, so that the round metal plate 00 cannot move and can stay at the preset position according to the setting each time, ensuring the accuracy of the subsequent transfer and other processing. At the same time, it can adapt to the material limiting demand of round metal plates 00 of different sizes, improve the application range and the reliability of material limiting. The limiting magnet 12 is composed of a magnet block.

[0027] As shown in Figure 3 , the lower side of the conveying roller 11 is provided with a receiving groove 13 for receiving and recycling the auxiliary agent dripping, and a curtain 14 is arranged between the receiving grooves 13 of the roller conveying mechanism in a suspended manner, and the curtain 14 is arranged around the receiving groove 13. The curtain 14 is mainly arranged to avoid dust and sundries from entering the receiving groove 13. The frame 10 is provided with a cover body 30, and the feeding mechanism and the auxiliary agent uniform distribution mechanism are arranged in the cover body 30.

[0028] As shown in Figure 4The replenishing mechanism is composed of replenishing units arranged at intervals along the length direction of the auxiliary agent uniformizing roller 30, and the replenishing units replenish the auxiliary agent to different sections of the auxiliary agent uniformizing roller 30 respectively. The replenishing unit comprises a replenishing tank 41 arranged at the side of the auxiliary agent tank, the lower part of the replenishing tank 41 is connected with the tank cavity of the auxiliary agent tank 40 through a connecting pipe, the bottom of the replenishing tank 41 is connected with a replenishing needle 46 through a liquid outlet pipe 42, the replenishing needle 46 is vertically fixed and installed on the upper side of the auxiliary agent uniformizing roller 30, the liquid outlet pipe 42 is provided with an adjuster 43 for adjusting the dripping speed of the replenishing needle 46, the liquid outlet pipe 42 is a soft plastic pipe, the adjuster 43 comprises an adjusting seat arranged on the liquid outlet pipe 42, the adjusting seat is provided with a rotatingly installed adjusting cam 44, the adjusting cam 44 is provided with a rotating handle 45, rotating the adjusting cam 44 causes the outer circumferential surface of the adjusting cam 44 to extrude and deform the pipe body of the liquid outlet pipe 42, so as to adjust the liquid outlet speed of the replenishing needle 46, and the liquid outlet speed of each adjusting unit gradually decreases from the middle part to the two outer sides of the auxiliary agent uniformizing roller 30. The replenishing tank 41 can be made of transparent material, the upper end of the replenishing tank 41 is provided with a pressure regulating pipe joint, and the pressure regulating pipe joint is provided with an adjusting valve. The replenishing tank 41 can be arranged in a staggered manner at the two outer sides of the auxiliary agent tank 40, a row of replenishing needles 46 are arranged on the lower side of the tank bottom of the auxiliary agent tank 40, the replenishing needles 46 are connected with the replenishing tanks 41 respectively, and rotating the adjusting cam 44 causes the outflow speed of the replenishing needles 46 to be preset. The replenishing needle is located on the upper side of the auxiliary agent uniformizing roller 30. Since the object to be coated is a circular metal plate, the coating area of the auxiliary agent uniformizing roller 30 is different at different sections, so that the consumption of the auxiliary agent at different sections is different. Generally, the replenishing mechanism uniformly replenishes the auxiliary agent, so that the coating amount of the auxiliary agent on the two sides of the circular metal plate 00 along the conveying direction of the roller cylinder conveying mechanism is less than the coating amount of the auxiliary agent on the middle part. In the above scheme, the dripping speed of the replenishing needle 46 corresponding to different sections is adjusted, so that more consumption is replenished more and less consumption is replenished less, so that the consistency of the auxiliary agent content on each section of the uniformizing roller 30 is consistent during each coating, and the auxiliary agent is uniformly coated on the surface of the circular metal plate along the length direction of the auxiliary agent uniformizing roller 30, thereby improving the coating uniformity.

[0029] The above is only the preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
