Description

Technical Field

[0001] The invention relates to the technical field of paper towel production and processing, in particular to a cream coating machine. Background Art

[0002] The role of cream in the cream coating machine is to evenly coat the cream on the surface of the paper through coating technology to form a protective film, which is mainly used to improve the moisturizing, softness and smoothness of the paper. The invention patent with application number 202211303617.2 uses a double-layer paper formed by two single-layer papers to enter the coating machine together. After one of the papers is coated with cream, it is conducted out and compounded with the other paper, which can greatly save efficiency and does not require a single application of cream and then compounding again.

[0003] However, during the conduction process, after the paper reaches the coating position, it is coated with a layer of cream to form a relatively smooth film. At the secondary position, the roughness of the paper transmitted front and back is different. It is easy to slide horizontally on the conduction rod during conduction, and then the cream outlet and the paper are easily misaligned, affecting the accurate coating of the cream on the paper. In addition, when the cream is coated, the paper is tangent to the coating position of the roller. The roller rotates in the direction of the paper, which is easy to apply too much cream, causing the cream to be uneven on the paper. Summary of the invention

[0006] A preferred technical solution: A hydraulic piston is provided inside the material box, and the hydraulic piston is controlled to be sealed and retracted into the material box when the pressure is reduced, so that the cream in the material box maintains a certain pressure and overflows from the lower left side.

[0007] A preferred technical solution: heating elements are provided on the left and right sides of the dryer, and the paper after the cream is applied by the application structure is transmitted to the dryer position for heating and condensation.

[0008] A preferred technical solution: the transmission structure is provided with transmission teeth, a first roller, a gear rod, a second roller, and a gear block.

When the horizontal rod moves, the triangular bar squeezes the plastic bar and moves, and when the horizontal rod stops, the triangular bar stops moving and is blocked and fixed at the position of the plastic bar.

[0015] A better technical solution: the limit groove forms a concave shape on the upper and lower sides of the horizontal rod, and the horizontal rod and the limit rod are vertically translated relative to each other through the concave position, and the limit rod maintains a fixed position in the two horizontal rods that translate relative to each other.

[0016] Compared with the prior art, this technical solution has the following advantages: When applying the cream in the present invention, the paper passes through the middle of the movable structure, and the width of the movable structure is adjusted according to the size of the paper.

[0031] like Figures 1 to 6 As shown, the present invention proposes a cream coating machine, including a coating structure 1, a fixed plate 2, a guide roller 3, a guide roller 4, a machine 5, a dryer 6, and a support plate 7. The support plate 7, the fixed plate 2, and the machine 5 are sequentially connected and arranged from top to bottom. The coating structure 1 is slidably engaged with the inner side of the fixed plate 2, the guide roller 3 is arranged on the side of the fixed plate 2, and the two guide rollers 4 are horizontally arranged on the side of the support plate 7, and the leftmost guide roller 4 is located directly above the dryer 6. When the paper is guided upward by the guide roller 3, the paper passes through the coating structure 1 and is vertically dried in the dryer 6, and the paper is pulled out by the external winding force under the guidance of the guide roller 4; The machine 5 is provided with two first slide shafts 51 and second slide shafts 52 arranged horizontally. The double-layer paper is tangent to the first slide shaft 51 on the left side of the machine 5. After being driven by the first slide shaft 51 on the left side, the double-layer paper is separately driven on the first slide shaft 51 on the right side toward the guide roller 3 and the second slide shaft 52. The smearing structure 1 is provided with a conducting structure 11, a material box 12, a movable structure 13, and a cardboard 14. The conducting structure 11 and the movable structure 13 are respectively arranged on the side of the cardboard 14, and the movable structure 13 slides and translates with the conducting structure 11 at the top. One side of the movable structure 13 blocks the outlet of the material box 12. The material box 12 is fixed on the side of the cardboard 14, and the cream overflows from the lower left end of the material box 12 to the right side of the conducting structure 11. The cream is rotated and taken out by the conducting structure 11. The conducting structure 11 and the movable structure 13 are provided with two groups, which are staggered left and right with the vertical line of the cardboard 14 as the center, and are arranged to The paper driven by the guide roller 3 changes direction continuously between the two groups of conductive structures 11 and contacts the side of the conductive structure 11. A moving rod 131 is provided in the movable structure 13, and a connecting plate 132 and a baffle 133 are provided at the lower end of the moving rod 131, wherein the baffle 133 is aligned with the exit at the lower left end of the material box 12. When the moving rod 131 is manually translated, the two connecting plates 132 move to both sides of the paper to guide it, and drive the baffle 133 outside the connecting plate 132 to block the movement at the notch at the lower left end of the material box 12. At this time, the width of the notch at the lower left end of the material box 12 is aligned with the paper contacting the conductive structure 11.

[0032] In the present invention, the paper changes direction between the two conductive structures 11 and contacts each other, so that the contact points of the paper on the two conductive structures 11 are increased, and the stability of the paper during conduction is increased by guiding at different angles. In addition, according to whether the paper needs to be coated on both sides, the material box 12 can be controlled to overflow the cream to coat the paper, so that the paper is suitable for double-sided lamination.

[0033] In addition, a hydraulic piston is provided inside the material box 12, and the hydraulic piston is controlled to be sealed and retracted into the material box 12 when the pressure is reduced, so that the cream in the material box 12 maintains a certain pressure and overflows from the lower left side.

[0034] In addition, heating elements are provided on the left and right sides of the dryer 6, and the paper after the cream is applied by the application structure 1 is transmitted to the dryer 6 for heating and condensation.

[0035] In the present invention, the double-layer paper is separated after being conducted by the first sliding shaft 51, so that one of the papers enters the coating structure 1 from the guide roller 3, and the paper continuously changes direction in the coating structure 1 and contacts the side of the conductive structure 11. At this time, the cream in the material box 12 overflows from the lower left side with a certain pressure and is conducted to the side in contact with the paper, so that the left and right sides of the paper are coated with the cream. When applying the cream, the paper passes through the middle of the movable structure 13, and the width of the movable structure 13 is adjusted according to the size of the paper. At the same time, the movement of the movable structure 13 will drive the width of the outlet at the lower left end of the material box 12, so that the width of the cream overflowing from the material box 12 is consistent with the width of the paper, and the cream is conducted by the conductive structure 11 within the width range of the conductive structure 11 and accurately coated on the paper, preventing the paper transmission from easily sliding on the conductive structure 11 and staggered from the coating range, thereby avoiding inadequate coating of the cream.

[0036] Among them, the transmission structure 11 is provided with a transmission tooth 111, a first roller 112, a gear rod 113, a second roller 114, and a gear block 115. The gear rod 113 and the gear block 115 are respectively arranged on the central axes of the first roller 112 and the second roller 114, and the gear rod 113 and the gear block 115 are arranged in parallel on the inner side of the card plate 14. The transmission tooth 111 is arranged on the inner side of the card plate 14 and transmits rotation to the gear block 115 and the gear rod 113. The gear of the gear rod 113 is connected to the motor arranged inside the card plate 14. The motor drives the gear rod 113 to rotate counterclockwise, and rotates the gear block 115 counterclockwise under the gear transmission of the transmission tooth 111, so that the gear block 115 and the gear rod 113 rotate counterclockwise synchronously. After the first roller 112 drives the cream overflowing from the material box 12, the cream on the outer side of the first roller 112 is scraped and transferred by the counterclockwise rotation of the second roller 114.

[0037] In the present invention, the motor drives the gear rod 113 to rotate, and cooperates with the gear block 115 under the transmission of the conduction tooth 111, and drives the first roller 112 and the second roller 114 to rotate counterclockwise synchronously. At this time, the cream overflowing from the right side material box 12 is rotated upward and adhered by the first roller 112, and the cream is scraped off by the tangency between the second roller 114 and the first roller 112. The second roller 114 accurately scrapes and transfers the cream on the outside of the first roller 112, so the paper is transmitted upward on the outside of the second roller 114, and the second roller 114 on the right side of the paper rotates counterclockwise. The second roller 114 guides the paper frictionally and squeezes the cream out of the paper again, and presses the paper with cream adhered to it at the position of the movable structure 13 to make the cream on its surface flat.

[0038] Among them, the movable structure 13 is provided with a connecting rod 134 and a scraping structure 135 in a fixed state, and the moving rod 131 moves through the scraping structure 135 while sliding in the connecting rod 134. The two connecting rods 134 are fixed in parallel on the inner side of the clamping plate 14, and the left and right ends of the two moving rods 131 are arranged in the two connecting rods 134 and move parallel to each other. The moving rod 131 passes through the scraping structure 135 and slides vertically to each other. When the moving rod 131 moves horizontally, the scraping structure 135 remains fixed in a fixed state at the upper left position of the second roller shaft 114. When the connecting plate 132 moves horizontally following the moving rod 131, it drives the baffle 133 arranged on the outside of the connecting plate 132 to press and move against the notch at the lower left end of the material box 12.

[0039] In addition, the connecting plate 132 is formed by two arcs, the curvature of the arc is consistent with the outer sides of the first roller 112 and the second roller 114, and when the two moving rods 131 translate, the connecting plate 132, the second roller 114 and the surface of the first roller 112 are driven to slide, so that the width between the two connecting plates 132 is consistent with the width of the lower left outlet of the right material box 12. After the second roller 114 guides the paper, both sides of the paper pass through between the two moving rods 131, so that the width of the paper, the width of the cream transferred by the second roller 114 and the width of the lower left outlet of the material box 12 are all located between the two moving rods 131.

[0040] The paper passes through the two moving rods 131 in the present invention, and the width of the moving rod 131 is manually adjusted according to the width of the paper. When the width of the moving rod 131 is adjusted, the moving rod 131 moves in the connecting rod 134, and the moving rod 131 drives the connecting plate 132 to slide on the surface of the first roller 112 and the second roller 114. At this time, the baffle 133 moves at the lower left end outlet of the material box 12, and blocks a part of the lower left end outlet of the material box 12, so that the paper width is consistent with the width of the lower left end outlet of the material box 12, and the cream overflowing from the lower left end of the material box 12 is accurately transferred to the side of the paper through the first roller 112 and the second roller 114. In the process of transferring the cream, the scraping structure 135 is adjusted in advance to adjust the gap between the scraping structure 135 and the second roller 114, so that the lower end of the scraping structure 135 scrapes the thickness of the cream on the outer side of the second roller 114, controls the thickness of the cream, and makes the cream on the paper scraped and flattened on the side of the lower end of the scraping structure 135.

[0041] Among them, the scraping structure 135 is provided with a limiting rod 1351, a scraping strip 1352, a micrometer 1353, and a movable rod 1354. The micrometer 1353 is fixed and passes through the inside of the limiting rod 1351, so that the lower end of the micrometer 1353 is connected to the movable rod 1354. The scraping strip 1352 is arranged on the side of the movable rod 1354, and the scraping strip 1352 is against the paper guided by the second roller 114. When the micrometer 1353 is rotated, it drives the movable rod 1354 to rise and fall. The triangle plate 1355 is arranged at the lower end of the movable rod 1354, and there is a gap between the lowermost end of the triangle plate 1355 and the second roller 114. When the second roller 114 rotates counterclockwise, the cream on the outside is blocked by the triangle plate 1355 and scraped flat. When the second roller 114 rotates counterclockwise, it rubs against the paper in the opposite direction and transfers the cream from the second roller 114 to the side of the paper.

[0042] Furthermore, after the second roller 114 transfers the cream onto the paper, the paper moves vertically upward and contacts the outermost end of the scraper bar 1352 . Under the tension of the moving paper, the scraper bar 1352 presses the paper and smoothes the uneven cream.

[0043] Furthermore, the scraper bar 1352 is made of rubber, and bends and blocks a portion of the cream when it comes into contact with the paper, so that the contact between the moving paper and the scraper bar 1352 forms a scraping effect.

[0044] In the present invention, the micrometer 1353 is screwed to adjust the height of the movable rod 1354, so that the triangle plate 1355 forms a gap on the outside of the second roller 114 and scrapes off the excess cream, and smoothes the uneven cream. The paper moves upward after being stained with cream on the left side of the second roller 114. At this time, the cream on the paper is in an uneven state. As the paper moves upward and contacts the scraper bar 1352, the scraper bar 1352 resists the cream on the paper and scrapes it on the side of the paper, preventing the cream smeared on the paper from being uneven.

[0045] Among them, the moving rod 131 is provided with a triangular bar 1311, a horizontal rod 1312, a plastic bar 1313, and a limiting groove 1314. The limiting groove 1314 is located on the upper and lower sides of the horizontal rod 1312. The lower sides of both ends of the horizontal rod 1312 are provided with equidistantly arranged triangular bars 1311. The triangular bar 1311 and the plastic bar 1313 arranged on the inner side of the connecting rod 134 are consistent with each other. When the horizontal rod 1312 moves, the triangular bar 1311 squeezes the plastic bar 1313 and moves. When the horizontal rod 1312 stops, the triangular bar 1311 stops moving and is blocked and fixed at the position of the plastic bar 1313.

[0046] In addition, the limiting groove 1314 forms a concave shape on the upper and lower sides of the horizontal rod 1312, and the horizontal rod 1312 and the limiting rod 1351 are vertically translated relative to each other through the concave position, and the limiting rod 1351 maintains a fixed position in the two horizontal rods 1312 that translate relative to each other.

[0047] When the horizontal rod 1312 in the present invention moves, the limiting groove 1314 maintains vertical cross translation in the limiting rod 1351, ensuring that the two horizontal rods 1312 are parallel to each other, and when the horizontal rod 1312 moves, it drives the triangular bar 1311 to extrude the plastic strip 1313. When the horizontal rod 1312 stops, the triangular bar 1311 fits in the position of the plastic strip 1313 and is fixed. When the paper and the second roller 114 move laterally, the horizontal rod 1312 blocks the paper. By fixing the horizontal rod 1312, the paper is kept within a certain range for applying the cream, thereby preventing the problem of inaccurate application of the cream due to paper movement.

[0048] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
