Referring to fig. 1 to 5, the present invention provides a dialysis paper 1 coating machine, which comprises a guiding device 2, a coating device 3 and an adjusting device; the guide device 2 is used for tensioning the dialyzing paper 1 and enabling the dialyzing paper 1 to move directionally on a preset path of the coating machine; the coating device 3 comprises a glue container and a belt material roller 31; the glue container is provided with a glue containing cavity 32; the material carrying roller 31 is connected with the glue containing cavity 32 and the coating position S1 of the dialyzing paper 1; the adjusting device comprises a first adjusting component 41 and a second adjusting component 42; the first adjusting assembly 41 includes a scraper 412 located at a first adjusting position S2 and acting on the tape roll 31 to adjust the amount of tape of the tape roll 31, the first adjusting position S2 being located at one side of the tape roll 31; the second regulating member 42 includes a bar 422 at a second regulating position S3 to regulate the coating amount and the coating uniformity of the dialysis paper 1, and the second regulating position S3 is located behind the coating position S1 of the preset path.

It should be noted that the preset path is located inside the coating machine, and the position of the preset path is not fixed and can be changed due to the change of the position or model of each part in the guiding device 2; further, the coating position S1, the first adjustment position S2, and the second adjustment position S3 are also variably set inside the coater.

Further, the coating position S1 is a position where the coated surface of the dialysis paper 1 is in contact with the tape roll 31, and the tape roll 31 is rotated by a second motor (not shown) to tape the dialysis paper 1 in the glue containing chamber 32 to the coating position S1 and coat on the dialysis paper 1.

As shown in fig. 1, 2, 4 and 5, the guide device 2 includes a front guide roller 21, a front adjusting guide roller 22, a first enveloping roller 23, a second enveloping roller 24, a third enveloping roller 25, a rear adjusting guide roller 26 and a rear guide roller 27 in sequence on a preset path, and the dialyzing paper 1 is introduced into the coater from the front guide roller 21 and is led out of the coater from the rear guide roller 27. In addition, the dialysis paper 1 has a certain friction force with the material carrying roller 31 at the coating position S1, so that the glue on the material carrying roller 31 can be left on the coating surface of the dialysis paper 1; similarly, the dialysis paper 1 has a certain friction force against the bars 422 at the second adjusting position S3, so that the excess glue on the dialysis paper 1 can be removed from the coated surface by the bars 422, and the excess glue can flow to the area with insufficient glue or back to the glue containing cavity 32 by the squeezing action of the bars 422, so that the glue can be uniformly distributed on the coated surface.

As shown in fig. 3 and 4 and 5, the coating position S1 is located between the first wrapping roller 23 and the second wrapping roller 24; the second adjustment position S3 is located between the second enveloping roller 24 and the third enveloping roller 25.

It should be noted that the scraper 412 is mounted on a scraper seat 411 on one side of the tape roll 31, and the scraper seat 411 can drive the scraper 412 to move in the X-axis direction to approach or separate from the tape roll 31 to adjust the amount of glue carried by the tape roll 31 and thus the amount of glue applied by the tape roll 31 on the dialysis paper 1.

Furthermore, the guiding device 2 comprises a first air cylinder 231 for driving the first enveloping roller 23 in motion, a second air cylinder 241 for driving the second enveloping roller 24 in motion and a third air cylinder 251 for driving the third enveloping roller 25 in motion; the first cylinder 231 and the second cylinder 241 work together to bring the dialysis paper 1 into contact with the tape roll 31 at the coating position S1; the second cylinder 241 and the third cylinder 251 work together to bring the dialysis paper 1 into contact with the bars 422 in the second adjustment position S3. The common action in this embodiment means that the first cylinder 231, the second cylinder 241, and the third cylinder 251 are in a stretched state, which is a coating state of the dialysis paper 1; when the coating of one dialysis paper 1 is completed, the first cylinder 231, the second cylinder 241 and the third cylinder 251 should be changed from the extended state to the retracted state to form a space in which a new dialysis paper 1 is loaded.

In addition, it should be noted that the front adjusting guide roller 22 is movably disposed in the X direction to tension the dialyzing paper 1 and adjust the angle of the dialyzing paper 1 with respect to the first wrapping roller 23; the post-adjustment guide roller 26 is movably disposed in the X direction to tension the dialysis paper 1 and adjust the angle of the dialysis paper 1 with the third enveloping roller 25. When the wrap angle between the dialyzing paper 1 and the first enveloping roller 23 and the wrap angle between the dialyzing paper 1 and the third enveloping roller 25 need to be increased, the front adjusting guide roller 22 and the rear adjusting guide roller 26 can be driven to move towards the inner direction of the coating machine; on the contrary, the front and rear regulating

guide rollers

22 and 26 are driven to move toward the outside of the coater.

The top-view projection of the first adjusting position S2 and the second adjusting position S3 is located inside the opening of the glue containing cavity 32, so that the excess glue is recycled to the glue containing cavity 32, that is, the scraper 412 and the line bar 422 are located above the opening of the glue containing cavity 32, and the excess glue expelled by the first adjusting assembly 41 and the second adjusting assembly 42 can be recycled to the inside of the glue containing cavity 32 under the action of gravity. The second adjustment assembly 42 also includes a first motor 421 that drives rotation of a bar 422.

As shown in fig. 3, the coating device 3 further includes a second motor (not shown) for driving the belt roller 31 to rotate and a lifting assembly for driving the glue container to move up and down, the lifting assembly includes a hand wheel 33, a worm gear reducer 36 and a gear 34 and rack 35 lifting mechanism, one end of the hand wheel 33 is connected with a worm, the worm is meshed with a worm wheel, and the gear 34 is connected to an output end of the worm wheel and meshed with the rack 35. When the operator rotates the hand wheel 33, the motion is transmitted to the rack 35 through the worm, the worm wheel and the gear 34, so that the rack 35 drives the glue container to move up and down.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
