Specific implementation
[0022] The utility model is described below in detail, the technical scheme in the embodiment of the utility model is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.
[0023] The utility model discloses a printing board full-size coating roll coating device that is improved, and the technical scheme of the utility model is:
[0024] As Figure 1 Indicated, a printing board full-size coating roll coating device, including roll coater body 1, the double roll roll coater of being adopted in this application, and this kind of roll coater has complete control system, and basically can realize full-automatic coating function, and the discharge port of roll coater body 1 is provided with conveying belt 2, still includes;
[0025] Support frame 3, support frame 3 is set up in conveying belt 2 top, and support frame 3 is provided with drying assembly 4 in, and drying assembly 4 includes the drying groove 401 setting in conveying belt 2 top, when conveying belt 2 transports board, and hot air is blown out below drying groove 401, and the hot air drying operation of directly being coated to one side of board can be carried out;
[0026] Hot air machine 5, hot air machine 5 is set up in one side of conveying belt 2, and drying groove 401 is connected with the air outlet end of hot air machine 5 through pipeline;
[0027] Impurity removal box 6, the inner chamber of impurity removal box 6 is connected with the air inlet end of hot air machine 5 through pipeline, and the side, far from hot air machine 5 of impurity removal box 6, is connected with external air through pipeline;Although most of the time board is exposed in air during coating process, but under the guidance of hot air flow of hot air machine 5, air is more likely to contact board frequently, resulting in that dirt in air adheres on coating, and coating effect is influenced;Before this part of air is introduced, impurity removal box 6 is taken to remove dirt in air, and the adverse effect of this part is reduced.
[0028] AsFigure 2 As shown, in one embodiment, the drying assembly 4 includes a light rod 402 fixedly connected to the inner wall of the support frame 3, a movable screw 403 rotatably connected to the inner wall of the support frame 3, a motor 404 fixedly connected to one side of the support frame 3, the output end of the motor 404 being coaxially fixed with the movable screw 403, and the motor 404 being a servo motor 404 that can be electrically controlled to rotate.
[0029] The drying trough 401 expands outward from top to bottom. The expansion design of the drying trough 401 allows the hot air of the drying trough 401 to contact the board more comprehensively, thus accelerating the drying speed. In addition, the overall length of the moving screw 403 is greater than the width of the conveyor belt 2. The length of the moving screw 403 affects the range that the drying trough 401 can move in the horizontal direction.
[0030] Two connecting blocks 405 are fixedly connected to the upper surface of the drying tank 401. One of the connecting blocks 405 has a sliding hole that matches the smooth rod 402. The other connecting block 405 has a threaded hole that matches the moving screw 403. The other connecting block 405 is screwed to the moving screw 403.
[0031] like Figure 3 As shown, in one embodiment, a filter frame 7 is provided inside the impurity removal box 6. Ventilation holes are provided on both sides of the filter frame 7. The filter frame 7 can be directly separated from the impurity removal box 6 for easy replacement of consumables. An activated carbon adsorption layer 8 is provided inside the filter frame 7. A top cover 9 is provided on the top of the impurity removal box 6.
[0032] The specific working method is as follows: When the full-size coating roller coating device for the printed board is in use, the board material is placed into the roller coating machine body 1, and the roller coating machine body 1 is turned on to start the automatic coating operation. After the current board is coated, when a new board is placed in, the already coated board will be pushed onto the conveyor belt 2 located behind the roller coating machine body 1 (the roller coating machine body 1 also has material conveying capabilities). At this time, the hot air fan 5 and the motor 404 are turned on. The hot air fan 5 draws air from the outside through the pipe, which has been filtered and cleaned by the impurity removal box 6, and then heats it before introducing it into the drying tank 401 through the pipe. Afterwards, the hot air from the drying tank 401 blows directly onto the board, drying and curing the coating on the board. At the same time, the motor 404 drives the moving screw 403 to rotate. Under the action of the screw, the moving block moves the drying tank 401 left and right. With the delivery action of the conveyor belt 2, the entire board area is dried, accelerating the curing process. This can speed up the curing time of the coating, improve the efficiency of coating work, and since the curing can be completed on the conveyor belt 2 before unloading, the staff can also perform the loading and unloading operations more promptly, which can improve the continuity of the coating work to a certain extent.
[0033] The technical means disclosed by the utility model scheme are not limited to the technical means disclosed by the above technical means, and also include technical schemes composed of equivalent replacement of the above technical features. The unfinished matters of the utility model belong to the common knowledge of the person skilled in the art.
