[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Specific examples are given below.

[0033] like Figure 1-6As shown, a slit coater and a slit adjustment method thereof, comprising a coater body 1; a mover 11 is slidably connected to the middle of the coater body 1; a coating head 12 is slidably connected to the middle of the mover 11; two groups of tooth plates 13 are fixedly connected to the top of the coating head 12; two groups of first brackets 14 are fixedly connected to the top of the mover 11; a movable rod 15 is slidably connected to the inner wall of the first bracket 14; an elastic member 16 is fixedly connected to the side wall of one group of the first brackets 14; a metal plate 17 is fixedly connected to the end of the elastic member 16, and the inner wall of the metal plate 17 and the end of the movable rod 15 are rotatably connected; the movable Two sets of gears 18 are fixedly connected to the middle of the rod 15, and the two sets of gears 18 and the two sets of tooth plates 13 are meshed with each other; a card frame 19 is fixedly connected to the top of the mover 11; a fixed block 110 is fixedly connected to the middle of the movable rod 15, and the fixed block 110 and the card frame 19 are matched in shape; when working, the staff can install the coating machine body 1 in the designated working area, and connect the pipeline in the middle of the coating head 12 with the external pump body. At this time, when the staff needs to adjust the total working height of the coating head 12, they can hold the end of the tool and sink it into the inner wall of the adjustment groove 111, and then squeeze it The movable rod 15 as a whole slides in the middle of the two groups of first brackets 14, so that the movable rod 15 can squeeze the middle of the elastic member 16 and stretch it when moving, until the fixed block 110 is completely separated from the inner wall of the card frame 19, the staff can rotate the movable rod 15 as a whole, and make the two groups of gears 18 drive the toothed plate 13 to move downward, until the coating head 12 is adjusted to the specified position as a whole, and then the support for the adjustment slot 111 can be released, and under the action of the resetting of the elastic member 16, the fixed block 110 is sunk into the inner wall of the card frame 19 again and the movable rod 15 as a whole is fixed, and then the base cloth can be placed It is arranged in the top area of ​​the coating machine body 1, and cooperates with the moving mover 11 to enable the coating head 12 to coat the base cloth. This step cooperates with the two sets of gears 18 to improve the convenience of adjusting the position of the coating head 12, and reduces the problem of unequal forces when the two sets of adjustment rods rotate in sequence, causing the coating head 12 to get stuck when moving downward. At the same time, a polygonal fixing block 110 is provided to improve the stability of the working position of the coating head 12 as a whole when it is moving. Under the action of the elastic member 16, the problem of needing to manually reset the movable rod 15 later can be reduced.

[0034] like Figure 3 and 6As shown, the side wall of the mover 11 is fixedly connected to a fixed plate 2; the top of the fixed plate 2 is fixedly connected to an elastic sheet 21; the end of the elastic sheet 21 is fixedly connected to a metal cavity 22, and the metal cavity 22 is arranged close to the side of the metal plate 17; the inner wall of the metal cavity 22 is provided with a plurality of groups of impact balls 23; the outer wall of the metal cavity 22 is fixedly connected to a magnetic block 24, and the magnetic block 24 and the metal plate 17 are arranged to attract each other; when working, by providing the metal cavity 22 on the outer wall, when the staff squeezes the movable rod 15 to expand outward, the position of the metal plate 17 will gradually approach the position of the magnetic block 24 until the two are in contact and adsorbed together, and after continuing to push the movable rod 15, the middle part of the elastic sheet 21 can be squeezed to bend and deform, and the subsequent After the movable rod 15 is reset in the reverse direction, it can simultaneously pull the middle part of the elastic sheet 21 to bend and deform again, so that after the pulling force reaches a certain amount, the magnetic block 24 and the metal plate 17 can be separated, and the elastic sheet 21 drives the metal cavity 22 to shake, and multiple groups of impact balls 23 will collide together and produce sound. This step, combined with the sound produced by the shaking of the impact balls 23, can be used to remind the staff that the card frame 19 and the fixed block 110 are completely closed, reducing the problem that the staff is difficult to detect between the fixed block 110 and the card frame 19 after the position misalignment between the two. The set magnetic block 24 can enhance the adhesion between the metal cavity 22 and the metal plate 17, thereby increasing the overall shaking frequency of the metal cavity 22.

[0035] like Figure 1 , 2 As shown in Figure 5, the side wall of the coater body 1 is provided with two groups of second brackets 3; the inner wall of the second bracket 3 is slidably connected to a slide bar 31; the end of the slide bar 31 is fixedly connected to a counterweight 32; the other end of the slide bar 31 is fixedly connected to a frame rod 33; the middle of the frame rod 33 is rotatably connected to a rotating wheel 34; the side wall of the mover 11 is fixedly connected to two groups of top plates 35, and the top plates 35 are arranged close to the side of the rotating wheel 34; the top of the top plates 35 is gradually inclined; when working, by arranging two groups of counterweights 32 in the middle of the coater body 1, when the mover 11 is reset as a whole, the inclined top plate 35 can contact the middle of the magnetic block 24 and move the counterweight 32 as a whole Lift it up, and then the base cloth can be placed on the top of the coater body 1 and located in the bottom area of ​​the two sets of counterweights 32. After the subsequent mover 11 moves again and performs the coating work, the wheel 34 will rotate in the middle of the frame rod 33 under the action of friction, and the two sets of counterweights 32 will synchronously descend and press down and clamp the ends of the base cloth. Under the action of the two sets of counterweights 32, this step can improve the stability of the base cloth when it is placed on the top of the coater body 1, and reduce the problem of the base cloth offset when the coating head 12 is performing the coating work. At the same time, the top plate 35 is set to achieve synchronization when the base cloth is stored or placed, and cooperate with the wheel 34 to reduce the resistance generated when the two are in contact.

[0036] like Figure 5 As shown, the side wall of the coater body 1 is slidably connected with an adjustment plate 4, and the adjustment plate 4 and the second bracket 3 are fixedly connected; two sets of fixing parts 41 are fixedly connected to the end of the coater body 1; a screw 42 is rotatably connected to the middle of the fixing part 41, and the other end of the screw 42 is rotatably connected to the inner wall of the coater body 1; the adjustment plate 4 and the screw 42 are threadedly connected; a handle 43 is fixedly connected to the end of the screw 42; when working, the fixing part 41 is arranged on the outer wall of the coater body 1, and the counterweight needs to be adjusted later When the block 32 is not adjusted, the staff can hold the middle part of the handle 43 and rotate it, so that the screw 42 can rotate synchronously, and drive the adjustment plate 4 as a whole to slide in the side wall area of ​​the coater body 1, and complete the position adjustment of the counterweight block 32. This step is combined with the setting of a slidable adjustment plate 4 to enhance the flexibility of the counterweight block 32 during use and reduce the basic size inequality placed on the top of the coater body 1, which makes it difficult for the subsequent counterweight block 32 and the top plate 35 to cooperate in fixing one end of the base cloth.

[0037] like Figure 3 As shown, the side wall of the mover 11 is fixedly connected to a support frame 5; the middle part of the support frame 5 is fixedly connected to a scale plate 51; the side wall of the coating head 12 is fixedly connected to an arrow 52, ​​and the arrow 52 is arranged close to the scale plate 51; during operation, by arranging the support frame 5 in the middle part of the coating machine body 1, the support frame 5 can support the position of the scale plate 51, and when the coating head 12 is subsequently adjusted to a high spacing, the arrow 52 can be made to move synchronously, and cooperate with the area of ​​the scale plate 51 indicated by the end of the arrow 52, ​​so as to complete the adjustment. This step cooperates with the set scale plate 51 and arrow 52 to improve the adjustment accuracy of the coating head 12, and reduce the trouble of the staff having to repeatedly bend over to observe the spacing between the coating head 12 and the top of the coating machine body 1.

[0038] like Figure 5 As shown, a storage groove 6 is provided on the top of the counterweight block 32; an elastic strip 61 is fixedly connected to the inner wall of the storage groove 6; during operation, the storage groove 6 is provided in the middle of the counterweight block 32, and subsequent staff can place an appropriate amount of heavy objects on the inner wall of the storage groove 6, and pull the elastic strip 61 upwards, and cooperate with its reverse force to reinforce the position of the heavy objects. In this step, under the action of the elastic strip 61, the damage caused by the heavier counterweight block 32 to the thinner base cloth can be reduced. At the same time, the elastic strip 61 can improve the stability of the heavy objects when they are placed on the inner wall of the storage groove 6.

[0039] like Figure 5As shown, an elastic cloth 7 is fixedly connected to the middle of the adjustment plate 4, and the other end of the elastic cloth 7 is fixedly connected to the side wall of the coater body 1; when working, the elastic cloth 7 is arranged in the middle of the adjustment plate 4, and the stretched elastic cloth 7 can cover the inner groove of the screw 42 exposed to the outside. Under the action of the elastic cloth 7, this step can reduce the problem of large resistance when the handle 43 is subsequently turned due to one side of the screw 42 not being used for a long time.

[0040] like Figure 5 As shown, a friction pad 8 is fixedly connected to the bottom of the counterweight block 32; during operation, by arranging the friction pad 8 at the bottom of the counterweight block 32, when the counterweight block 32 approaches the base cloth, the friction pad 8 can first contact the base cloth. Under the action of the friction pad 8, this step can further improve the stability when fixing one end of the base cloth, thereby improving the friction between the two.

[0041] like Figure 7 As shown, a method for adjusting the slit of a slit coater is applicable to the above-mentioned slit coater, and the method comprises the following steps:

[0042] S1: After connecting the external pump body to the coating head 12, check and confirm that the power supply of the coating machine body 1 and the pump body is connected so that it can provide a stable power supply to the coating machine body 1, and then take out the hexagonal wrench matching the adjustment slot 111 from the tool box;

[0043] S2: Insert the hexagonal wrench into the inner groove of the adjustment groove 111, push the movable rod 15 to completely disengage the fixed block 110 from the clamping frame 19, and rotate the movable rod 15 to make the coating head 12 drop as a whole, and the coating head 12 can be supported by the elastic device at the bottom thereof, so that the output end of the coating head 12 gradually approaches the base cloth at the top of the coating machine body 1;

[0044] S3: After the coating head 12 is lowered, the staff can observe the position of the synchronously moving arrow 52. When the end of the arrow 52 indicates the required scale, the support for the adjustment slot 111 can be released, and the fixing block 110 and the card frame 19 can be cooperated to complete the overall fixing work.

[0045] Working principle: After the coating machine body 1 is installed in the designated working area, and the pipe in the middle of the coating head 12 is connected to the external pump body, when the staff needs to adjust the total working height of the coating head 12, the end of the tool can be held and sunk into the inner wall of the adjustment groove 111, and the movable rod 15 can be squeezed to slide in the middle of the two groups of first brackets 14, so that the movable rod 15 can squeeze the middle of the elastic member 16 and stretch it during movement, until the fixed block 110 is completely separated from the inner wall of the card frame 19, the staff can rotate the movable rod 15 as a whole, and make the two groups of gears 18 drive the tooth plate 13 to move downward, until the coating head 12 is adjusted to the designated position as a whole, and then the support for the adjustment groove 111 can be released, and the elastic member 16 can be adjusted to the designated position as a whole. Under the action of the reset of the member 16, the fixed block 110 is again sunk into the inner wall of the card frame 19 and the movable rod 15 is fixed as a whole. Then the base cloth can be placed in the top area of ​​the coating machine body 1, and the coating head 12 is used to coat the base cloth in cooperation with the moving mover 11. By providing a metal cavity 22 on the outer wall, when the staff squeezes the movable rod 15 to expand outward, the position of the metal plate 17 will gradually approach the position of the magnetic block 24 until the two are in contact and adsorbed together. After continuing to push the movable rod 15, the middle part of the elastic sheet 21 can be squeezed to bend and deform. At the same time, after the subsequent movable rod 15 is reset in the reverse direction, the middle part of the elastic sheet 21 can be pulled to bend and deform again, so that after the pulling force reaches a certain amount, the magnetic block 24 and the metal plate 17 can be separated, and the elastic sheet 21 drives the metal cavity 22 to shake, and the multiple groups of impact balls 23 will collide with each other and produce sound. By setting two groups of counterweight blocks 32 in the middle of the coater body 1, when the mover 11 is reset as a whole, the inclined top plate 35 can contact the middle of the magnetic block 24 and lift the counterweight block 32 as a whole, and then the base cloth can be placed on the top of the coater body 1 and located at the bottom area of ​​the two groups of counterweight blocks 32. After the subsequent mover 11 moves again and performs the coating work, the rotating wheel 34 will rotate in the middle of the frame rod 33 under the action of friction, and the two groups of counterweight blocks 32 will synchronously descend and press down the end of the base cloth. , and when the position of the counterweight block 32 needs to be adjusted later, the staff can hold the middle part of the handle 43 and rotate it, so that the screw 42 can rotate synchronously, and drive the adjustment plate 4 as a whole to slide in the side wall area of ​​the coater body 1, and complete the position adjustment of the counterweight block 32. By providing a support frame 5 in the middle part of the coater body 1, the support frame 5 can support the position of the scale plate 51, and when the coating head 12 is subsequently adjusted in height, the arrow 52 can be moved synchronously, and cooperate with the scale plate 51 area indicated by the end of the arrow 52 to complete the adjustment. By providing a storage groove 6 in the middle part of the counterweight block 32, the staff can subsequently place an appropriate amount of weight on the inner wall of the storage groove 6 and pull the elastic strip 61 upwards,In order to reinforce the position of the weight with the reverse force, an elastic cloth 7 is arranged in the middle of the adjustment plate 4, and the stretched elastic cloth 7 can cover the inner groove of the screw 42 exposed to the outside, and a friction pad 8 is arranged at the bottom of the counterweight 32, and when the counterweight 32 approaches the base cloth, the friction pad 8 can first contact the base cloth.
