[0002] Embossing is an important process in the production of paper towels. Its purpose is to form certain patterns or designs on the surface of paper towels to improve the aesthetics and user experience of paper towels. At the same time, embossing can also increase the compactness and water absorption of paper towels, making them more durable and practical. In the production process of paper towels, the embossing device is one of the indispensable equipment. By embossing the paper towels with the embossing roller of the embossing device, the embossing operation can be completed quickly and efficiently, thereby improving the production efficiency of paper towels. Chinese patent CN217863073U discloses an embossing device for paper product production, which can meet the embossing requirements of paper products of different thicknesses by adjusting the spacing between the embossing roller and the conveying roller. However, when the embossing depth needs to be adjusted, the embossing roller with the required embossing height needs to be disassembled and replaced to achieve the purpose of adjusting the embossing depth. Utility Model Content

[0003] The utility model aims to solve the above-mentioned technical problems and to provide an embossing device for paper production, which can adjust the embossing depth of the embossing roller without replacing the embossing roller.

[0004] In view of this, the utility model provides an embossing device for paper production, comprising a frame and an embossing kit arranged on the frame, the embossing kit comprising an embossing roller and a pressing roller, the embossing roller comprising: an outer sleeve, the outer sleeve being provided with an embossing channel; an embossing block, the embossing block being provided with embossings capable of exposing the embossing channel; an inner sleeve, the inner sleeve being coaxially fixedly connected in the outer sleeve, a bidirectional screw being coaxially arranged in the inner sleeve; and an extrusion piece, the extrusion piece being threadedly connected to both sides of the bidirectional screw.

[0005] In the present technical solution, when the embossing depth needs to be deepened, the bidirectional screw is rotated to make the extrusion parts threadedly connected to the two ends of the bidirectional screw move toward each other, and the extrusion block presses the embossing block to move, so that the embossing on the embossing block is more exposed to the outer sleeve through the embossing channel, thereby deepening the embossing depth of the paper towel. The embossing depth is convenient to adjust, and there is no need to disassemble and replace the embossing roller with the required embossing height to achieve the purpose of adjusting the embossing depth.

[0006] In the above technical solution, further, the stamping block is arranged along the circumference of the inner sleeve, and a sliding channel is arranged on the side of the stamping block away from the embossing. A sliding column is slidably connected in the sliding channel, and the sliding column is fixedly connected to the surface of the inner sleeve.

[0007] In this technical solution, the sliding connection between the sliding channel and the sliding column is used to limit the directional movement of the stamping block during movement, thereby preventing the stamping block from rotating in the outer sleeve, causing the embossing of the stamping block and the embossing channel on the outer sleeve to be misaligned and interfere with each other.

[0008] In the above technical solution, further, the extruded part is a hollow conical block, a connecting block is arranged in the middle of the conical block, and the connecting block passes through a slide groove arranged on the inner sleeve and is fixedly connected to a threaded sleeve threadedly connected to the bidirectional screw rod.

[0009] In this technical solution, the bidirectional screw rod rotates to drive the threaded sleeve to move, and the threaded sleeve drives the stamping block to move along the slide groove through the connecting block.

[0010] In the above technical solution, further, the stamping block is provided with arc-shaped notches at both ends of one side of the sliding channel corresponding to the extrusion piece.

[0011] In the present technical solution, the angle of the arc-shaped notch of the stamping block is consistent with the angle of the extrusion piece. When the bidirectional screw rotates, the stamping blocks on both sides move toward each other, squeezing the arc-shaped notch of the stamping block arranged on the circumference, forcing the stamping block to move outward, so that the embossing on the stamping block exposes more of the embossing channel, thereby achieving the purpose of adjusting the embossing depth.

[0012] In the above technical solution, further, one end of the bidirectional screw rod passes through the embossing roller body and is fixedly connected to a rotating wheel.

[0013] In this technical solution, the operator can directly rotate the internal bidirectional screw more conveniently through the rotating wheel, thereby controlling the extrusion of the extrusion piece on the stamping block, and more accurately controlling the length of the embossing channel exposed by the embossing, thereby adjusting the embossing depth.

[0014] In the above technical solution, further, the embossing roller is rotatably arranged on a support block, the support block is fixedly connected to the support plate, and the embossing roller and the first motor are driven by a pulley belt.

[0015] In this technical solution, the embossing roller is connected to the support block bearing, and a pulley is coaxially fixedly connected to one side of the embossing roller. The pulley and the coaxially fixed connection to the first motor are driven by a belt transmission, and the belt passes through the empty groove on the support plate.

[0016] In the above technical solution, further, a pressure roller is threadedly connected to the threaded rods on both sides through a support assembly, the threaded rods are vertically arranged in the fixed plates on both sides, a transmission rod is arranged under the support plate, a second motor is coaxially fixed at one end of the transmission rod, and the transmission rod and the threaded rods on both sides are driven by a bevel gear set.

[0017] In this technical solution, the second motor drives the transmission rod to rotate synchronously, and the transmission rod transmits the threaded rods on both sides through the bevel gear set, driving the threaded rods on both sides to rotate synchronously, so that the supporting assembly threadedly connected to the threaded rod moves, completing the operation of the embossing roller approaching or moving away from the embossing roller. The transmission of the thread by the bevel gear set and the transmission rod is a mature existing technology, so it will not be elaborated in detail.

[0018] In the above technical solution, further, the supporting assembly includes a cross bar, the two sides of which are slidably arranged on the outer wall of the slide, the slide and the threaded rod are threadedly connected, limiting rings are arranged on the upper and lower sides of the slide, a first spring is fixedly arranged between the cross bar and the upper limiting ring, and the cross bar is connected to the lower pressure roller through a connecting plate.

[0019] In this technical solution, the pressing roller is connected to the connecting plates on both sides through the bearing. The threaded rod rotates to drive the slide to move, and the pressing roller is driven to move through the cross bar. At the same time, the cross bar abuts against the lower limit ring of the slide, and is connected to the upper limit ring through the first spring. Under the squeezing and buffering action of the first spring, the embossing roller and the pressing roller can be better squeezed and contacted, which is beneficial to improving the quality of paper embossing.

[0020] The beneficial effects of the utility model are:

[0037] Embodiment 1:

[0038] The present embodiment provides an embossing device for paper production, comprising a frame and an embossing kit 1 arranged on the frame, the embossing kit 1 comprising an embossing roller 2 and a pressing roller 3, the embossing roller 2 comprising: an outer sleeve 4, the outer sleeve 4 having an embossing channel 5 extending therethrough; an embossing block 6, the embossing block 6 having an embossing pattern 7 capable of exposing the embossing channel 5; an inner sleeve 8, the inner sleeve 8 being coaxially fixedly connected in the outer sleeve 4, the inner sleeve 8 having a bidirectional screw 9 coaxially arranged therein; and an extrusion piece 10, the extrusion piece 10 being threadedly connected to both sides of the bidirectional screw 9. When the embossing depth needs to be deepened, the bidirectional screw 9 is rotated to make the extrusion pieces 10 threadedly connected to both ends of the bidirectional screw 9 move toward each other, the extrusion block presses the embossing block 6 to move, so that the embossing pattern 7 on the embossing block 6 is more exposed to the outer sleeve 4 through the embossing channel 5, thereby deepening the embossing depth of the paper towel, and the embossing depth can be adjusted conveniently, and the embossing depth can be adjusted without disassembling and replacing the embossing roller 2 having the required embossing pattern 7 height.

[0039] In this embodiment, the embossing channel 5 is a round hole, and the corresponding embossing 7 on the embossing block 6 is set to be columnar. In other embodiments of the utility model, the embossing channel 5 can be any pattern that needs to be embossed on the paper towel, and the embossing 7 on the embossing block 6 can be set corresponding to the embossing channel 5.

[0040] The stamping block 6 is arranged along the circumference of the inner sleeve 8, and a sliding channel 11 is arranged on the side of the stamping block 6 away from the embossing 7. A sliding column 12 is slidably connected in the sliding channel 11, and the sliding column 12 is fixedly connected to the surface of the inner sleeve 8. Through the sliding connection between the sliding channel 11 and the sliding column 12, the directional movement of the stamping block 6 is restricted when it moves, so as to avoid the stamping block 6 rotating in the outer sleeve 4, which causes the embossing 7 of the stamping block 6 and the embossing channel 5 on the outer sleeve 4 to be misaligned and interfere with each other.

[0041] The extrusion piece 10 is a hollow conical block, and a connecting block 13 is arranged in the middle of the conical block. The connecting block 13 passes through the slide groove 14 arranged on the inner sleeve 8 and is fixedly connected with the threaded sleeve 15 threadedly connected to the bidirectional screw 9. The bidirectional screw 9 rotates to drive the threaded sleeve 15 to move, and the threaded sleeve 15 drives the stamping block 6 to move along the slide groove 14 through the connecting block 13.

[0042] The two ends of the stamping block 6 on one side of the sliding channel 11 are provided with arc-shaped notches 16 corresponding to the extrusion piece 10. The angle of the arc-shaped notch 16 of the stamping block 6 is consistent with the angle of the extrusion piece 10. When the bidirectional screw 9 rotates, the stamping blocks 6 on both sides move toward each other, and the arc-shaped notches 16 of the stamping block 6 set on the circumference are squeezed, forcing the stamping block 6 to move outward, so that the embossing 7 on the stamping block 6 is more exposed to the embossing channel 5, so as to achieve the purpose of adjusting the embossing depth.

[0043] One end of the bidirectional screw 9 passes through the roller body of the embossing roller 2 and is fixedly connected to a rotating wheel 17. The operator can conveniently and directly rotate the internal bidirectional screw 9 through the rotating wheel 17, thereby controlling the extrusion of the extrusion member 10 on the stamping block 6, and more accurately controlling the length of the embossing channel 5 exposed by the embossing 7, thereby adjusting the embossing depth.
