[0021] For the convenience of understanding of those skilled in the art, the utility model is further explained below in combination with examples and drawings, and the content mentioned in the implementation mode is not a limitation on the utility model. The utility model is described in detail below in combination with drawings.

[0022] As shown in Figures 1 to 4 The utility model provides a three roll coating module of easy to adjust gap, including pressure roller 1, coating roll 2 and transfer roll 3 that are sequentially arranged from top to bottom, and the gap 6 for letting film material pass through is formed between coating roll 2 and pressure roller 1, and the both ends of transfer roll 3 are respectively provided with height adjusting mechanism 4, height adjusting mechanism 4 includes transfer bearing seat 41, height adjusting drive part 42 and height adjusting transmission assembly 43, and the both ends of transfer roll 3 are respectively rotationally arranged in the transfer bearing seat 41 of two height adjusting mechanism 4, and height adjusting drive part 42 is drivenly connected with transfer bearing seat 41 through height adjusting transmission assembly 43.

[0023] The utility model is applied to coating machine, and pressure roller 1, coating roll 2 and transfer roll 3 have drive module (not shown in the drawing) for driving respectively. After being dipped with paint, transfer roll 3 is transferred to coating roll 2, and then coating roll 2 coats the paint on the film material passing through gap 6, thereby completing the coating action.

[0024] When the depth of gap 6 needs to be adjusted, height adjusting drive part 42 only needs to act, and transfer bearing seat 41 is lifted through height adjusting transmission assembly 43, thereby realizing the effect of controlling the lifting of transfer roll 3: if it needs to rise, then coating roll 2 is lifted together by the rising of transfer roll 3; if it needs to descend, then coating roll 2 descends under the action of gravity while transfer roll 3 descends.

[0025] In the embodiment, height adjusting transmission assembly 43 includes lever 431 and rotating part 432, height adjusting drive part 42 is rotationally connected to one end of lever 431, and height adjusting drive part 42 is used to drive the lifting of one end of lever 431, and the other end of lever 431 is used to rotationally connect the external coating machine; the both ends of rotating part 432 are respectively rotationally connected to lever 431 and transfer bearing seat 41.

[0026] In actual use, height adjusting drive part 42 includes a cylinder, and the piston rod of the cylinder is rotationally connected to one end of lever 431. The above-mentioned rotationally arranged structure is to ensure that the linear action of the corresponding structure will not deviate. When height adjustment is needed, height adjusting drive part 42 acts, and the lifting of rotating part 432 is controlled by using the lever principle, thereby driving the lifting of transfer bearing seat 41. Rotating part 432 is preferably rotationally connected to the middle part of lever 431, thereby the height variation of transfer bearing seat 41 is half of the driving stroke of height adjusting drive part 42 when transmission, and it is more beneficial to improve the accuracy of height adjustment.

[0027] Specifically, the height adjusting mechanism 4 further comprises a guide rail 44, and the transfer bearing seat 41 is slidingly arranged on the guide rail 44, and the guide rail 44 is used for guiding the transfer bearing seat 41 to ascend or descend in the vertical direction, so as to ensure that the transfer roller 3 does not deviate.

[0028] In the embodiment, the limiting mechanism 5 is further included, the limiting mechanism 5 comprises a limiting block 51, a position adjusting piece 52 and a contact piece 53, the contact piece 53 is arranged on the coating roller 2, the limiting block 51 is located directly above the contact piece 53, the limiting block 51 is provided with an inclined surface used for abutting against the contact piece 53, and the position adjusting piece 52 is used for driving the limiting block 51 to move so as to adjust the relative position between the inclined surface and the contact piece 53.

[0029] In actual use, the limiting mechanism 5 is arranged at both ends of the coating roller 2, and before the gap 6 is adjusted, the position adjusting piece 52 is used to control the limiting block 51 to move (for example, leftward or rightward in the drawing) so as to adjust the position at which the inclined surface abuts against the contact piece 53 according to the depth of the gap 6 after the adjustment, and then the height adjusting mechanism 4 is used to control the transfer roller 3 and the coating roller 2 to ascend until the contact piece 53 contacts the inclined surface, that is, the depth of the gap 6 between the coating roller 2 and the compression roller 1 reaches the required depth.

[0030] Through the arrangement of the limiting mechanism 5, the depth precision of the gap 6 can be ensured, and the influence of the depth of the cylinder on the specific adjustment effect can be avoided.

[0031] Specifically, the coating roller 2 is provided with a coating bearing seat 21 at each end, the contact piece 53 has a wheel structure, the coating bearing seat 21 is provided with a mounting groove 22, the contact piece 53 is arranged in the mounting groove 22, and the top of the contact piece 53 protrudes above the mounting groove 22.

[0032] The coating bearing seat 21 is also slidingly arranged on the guide rail 44, and the wheel structure is used as the contact piece 53, so that the contact surface between the contact piece 53 and the inclined surface is smooth, and the stability and safety of the abutment are ensured.

[0033] Preferably, a fixing structure 56 is arranged between the coating bearing seat 21 and the contact piece 53, the fixing structure 56 is used for preventing the contact piece 53 from rotating and moving in the mounting groove 22, and the stability of the abutment with the inclined surface is ensured.

[0034] Specifically, the limiting mechanism 5 further comprises a limiting seat 54 and a limiting screw 55, the limiting screw 55 is screwed on the coating bearing seat 21, and the limiting seat 54 is used for abutting against the top of the limiting screw 55.

[0035] After the height is adjusted, the limiting screw 55 is supported by the limiting seat 54 to keep the height of the coating roller 2 by screwing the limiting screw 55, so that the coating roller 2 does not drop when the distance between the coating roller 2 and the transfer roller 3 needs to be adjusted.

[0036] Specifically, the position adjusting member 52 comprises a handle 521, a screw rod 522 and two fixing blocks 523. The limiting block 51 is screwed with the screw rod 522. The handle 521 is arranged at one end of the screw rod 522. The two fixing blocks 523 are used to prevent the screw rod 522 from moving along the length direction of the screw rod 522. That is, the handle 521 controls the screw rod 522 to rotate without moving forward and backward, so as to drive the limiting block 51 to move along the length direction of the screw rod 522, thereby achieving the effect of adjusting the relative position of the limiting block 51 and the abutting member 53.
