Description

Technical Field

[0001] This invention relates to the field of tissue paper production technology, and in particular to a high-efficiency tissue paper embossing device. Background Technology

[0002] Paper towels are used to dry off moisture or remove dirt. To increase the density of the paper, embossing is required during the paper towel production process. In addition, embossing can reduce the chance of the paper being flattened or deformed and the fibers being damaged during transportation. Embossing adds a textured feel and plays a proper cushioning role during transportation.

[0003] Chinese invention patent application CN114953606A discloses a high-efficiency tissue printing device, including a machine body and a monitoring system. Two pressure rollers are rotatably installed inside the machine body. A support plate is provided in front of the pressure rollers and is located inside the machine body. Two L-shaped limiting blocks are slidably installed on the support plate. A limiting mechanism is provided between the L-shaped limiting blocks and the support plate. The limiting mechanism includes a strip-shaped slide, a pressing block, and an inner slider. The inner slider is fixedly installed at the bottom of the L-shaped limiting block. A strip-shaped slide is provided on the surface of the support plate. The inner slider is slidably installed inside the strip-shaped slide. A bottom plate is provided at the bottom of the inner slider. The bottom of the support plate is in close contact with both ends of the bottom plate. A rod hole is provided on the inner slider. A rectangular groove is provided at the top of the L-shaped limiting block. A pressure rod passes through the rod hole. The bottom of the pressure rod is fixedly installed with the bottom plate. The top of the pressure rod is fixedly connected with the pressing block. A reset mechanism is provided between the pressure rod and the rod hole.

[0004] Existing technology utilizes a limiting mechanism to restrict the position of the L-shaped limiting blocks on the tray, which allows operators to adjust the positions of the two L-shaped limiting blocks in a timely manner, thereby improving adjustment efficiency and embossing efficiency. This solves the technical problem that the position of the L-shaped limiting blocks is not conducive to adjustment. However, for embossing, the embossing patterns are limited, and when different patterns need to be embossed, the pressure rollers need to be replaced. Furthermore, the embossing effect is poor for thicker tissues, and the cumbersome operation steps result in low embossing efficiency. Therefore, there is an urgent need for a high-efficiency tissue embossing device. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a high-efficiency tissue embossing device, comprising an extrusion mechanism and an embossing mechanism. The extrusion mechanism includes two sets of vertical frames and two sets of rollers. The two sets of vertical frames are symmetrically arranged at both ends of the rollers. The first set of rollers is rotatably mounted on the vertical frames at both ends. The second set of rollers has rectangular blocks rotatably mounted on both ends. The rectangular blocks are slidably mounted on the vertical frames. A cylinder is arranged between the rectangular blocks and the vertical frames. The cylinder adjusts the distance between the two sets of rollers. A pitch-changing component is arranged between the two sets of rollers. The pitch-changing component drives the two sets of rollers to rotate in opposite directions. Each set of rollers is provided with multiple embossing mechanisms. Each embossing mechanism includes a ring frame and multiple sets of patterned arc plates. The protrusions of the ring frame are slidably mounted on the axial grooves of the rollers. An adjustment component is arranged between the protrusions and the rollers. The adjustment component adjusts the position of the ring frame on the rollers. The patterned arc plates are slidably mounted on the axial rails of the ring frame. A baffle is slidably mounted on the arc rails of the ring frame. A positioning component is arranged on the baffle. The positioning component and the baffle help to fix the patterned arc plates. The patterns on the patterned arc plates have different shapes.

[0006] Furthermore, the pitch-changing assembly includes two sets of main gears and driven gears. Each set of main gears corresponds to a set of rollers, and the main gears are fixedly installed at the ends of the two sets of rollers respectively. A keyway is provided on the vertical frame, and the ends of the second set of rollers are rotatably and slidably mounted on the keyway. A motor is mounted on the motor frame of the vertical frame. The first set of main gears is fixedly installed on the output shaft of the motor, and the driven gear is rotatably mounted on the vertical frame, meshing with the first set of main gears. The motor drives the first set of main gears to rotate, and the first set of main gears drives the driven gears to rotate.

[0007] Furthermore, the pitch-changing assembly also includes a transmission gear and two sets of connecting rods. The first ends of the two sets of connecting rods are rotatably mounted on the transmission gear, the second ends of one set of connecting rods are rotatably mounted on a driven gear, and the second ends of the other set of connecting rods are rotatably mounted on a second set of main gears. The driven gear meshes with the transmission gear, and the transmission gear meshes with the second set of main gears. When the driven gear rotates, it drives the transmission gear to rotate. The transmission gear drives the second set of rollers to rotate through the second set of main gears. The two sets of rollers rotate in opposite directions. When the second set of rollers slides on the keyway of the vertical frame, it does not affect the rotation of the two sets of rollers.

[0008] Furthermore, the protrusion has a cavity inside, and the adjusting components are disposed inside the cavity. Two pairs of adjusting components are symmetrically arranged on each set of ring frames. Each adjusting component includes an adjusting rod, which is slidably mounted on the protrusion. The adjusting rods of each pair of adjusting components are coaxial. The two pairs of adjusting components make the position of the ring frame on the roller more stable. When the adjusting rods of each pair of adjusting components are working, the sliding directions of the adjusting rods are opposite.

[0009] Furthermore, the adjustment assembly also includes two sets of adjustment columns and an adjustment spring. Limiting holes are symmetrically arranged on both sides of the protrusion. The two sets of adjustment columns are symmetrically slidably mounted on the limiting holes of the protrusion. A pin seat is provided at the end of the adjustment rod, and a rocker arm is rotatably connected between the pin seat and the adjustment column. A spring plate is provided inside the protrusion, and the adjustment spring is located between the spring plate and the pin seat. Pressing the adjustment rod of each pair of adjustment components causes the two sets of adjustment rods to move towards each other, compressing the adjustment spring and causing the rocker arm to move towards the spring plate. The rocker arm then drives the two sets of adjustment columns to move towards each other, and the two sets of adjustment columns move closer to the axis of the adjustment rod.

[0010] Furthermore, multiple sets of adjusting holes are symmetrically arranged on both sides of the axial groove of the roller, and the adjusting holes are in contact with the adjusting columns. When the force applied to the adjusting rod of each pair of adjusting components is disconnected, the adjusting rod of each pair of adjusting components is pushed to move in the opposite direction under the elastic action of the adjusting spring, pushing the two sets of adjusting columns to move away from the axis of the adjusting rod. The adjusting columns slide on the limiting holes until the adjusting columns are in contact with the adjusting holes, at which point both the adjusting rod and the adjusting columns stop moving, and the position of the ring frame is fixed.

[0011] Furthermore, each set of baffles corresponds to a set of patterned arc plates, and each set of baffles corresponds to a set of positioning components. The baffles are provided with spring holes, and the positioning components are disposed on the spring holes. Each positioning component includes a positioning rod and a positioning spring. The positioning rod is slidably mounted on the baffle, and a positioning block is fixedly mounted on the end of the positioning rod. The positioning block is slidably mounted on the baffle, and a positioning groove is provided on the ring frame, with the positioning block contacting and engaging with the positioning groove. The positioning spring is disposed inside the spring hole, between the positioning block and the spring hole, and is slidably mounted on the positioning rod. When the positioning block engages with the positioning groove, the baffle closes the ring frame's axis, fixing the patterned arc plate on the ring frame. Pulling the positioning rod outward compresses the positioning spring, causing the positioning block to move outward from the positioning groove, breaking the engagement between the positioning block and the positioning groove. The positioning rod then pushes the baffle to slide on the arc track, releasing the restriction on the patterned arc plate, allowing it to be removed.

[0012] Furthermore, the adjusting component adjusts the distance between multiple sets of ring frames on the adjusting roller; according to the different patterns of the patterned arc plates, the combination of multiple sets of patterned arc plates on the ring frames is changed. Different distances between the ring frames can change the embossing distance, allowing embossing of paper towels of different widths; different patterns on the patterned arc plates on the ring frames allow for embossing with various pattern combinations.

[0013] The beneficial effects of this invention compared with the prior art are: (1) This invention is equipped with a variable pitch component, which can adjust the distance between two sets of rollers, thereby changing the distance between the embossing mechanisms on the rollers to adapt to paper towels of different thicknesses; (2) This invention is equipped with an embossing mechanism, which uses the adjustment component to change the distance between the adjustment mechanisms on the rollers to adapt to paper towels of different lengths, and has a wide range of applications; (3) This invention is equipped with a positioning component and a pattern arc plate. The positioning component fixes the pattern arc plate, which is convenient for disassembly and installation of the pattern arc plate. Different patterns are set on the pattern arc plate, so the combination of the pattern arc plates on the ring frame can be changed to perform different styles of embossing. This makes it convenient for workers to change the embossing style and the width of the paper towel. The operation is convenient, time-saving and labor-saving, and improves the embossing efficiency.

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example: Figures 1-15 The illustrated high-efficiency tissue embossing device includes an extrusion mechanism and an embossing mechanism. The extrusion mechanism includes two sets of vertical frames 11 and two sets of rollers 12. The two sets of vertical frames 11 are symmetrically arranged at both ends of the rollers 12. The first set of rollers 12 has rectangular blocks 13 rotatably mounted at both ends. The rectangular blocks 13 are slidably mounted on the vertical frames 11. A cylinder 14 is arranged between the rectangular blocks 13 and the vertical frames 11. The cylinder 14 adjusts the distance between the two sets of rollers 12. A pitch-changing assembly 15 is arranged between the two sets of rollers 12. The pitch-changing assembly 15 drives... Two sets of rollers 12 rotate in opposite directions; each set of rollers 12 is equipped with multiple embossing mechanisms, including a ring frame 2 and multiple sets of patterned arc plates 3. The protrusions 21 of the ring frame 2 are slidably installed on the axial grooves 121 of the rollers 12. An adjustment component is provided between the protrusions 21 and the rollers 12 to adjust the position of the ring frame 2 on the rollers 12. The patterned arc plates 3 are slidably installed on the axial rails of the ring frame 2. A baffle 5 is slidably installed on the arc rails 23 of the ring frame 2. A positioning component is provided on the baffle 5. The positioning component and the baffle 5 help to fix the patterned arc plates 3. The patterns on the patterned arc plates 3 are different shapes.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 7As shown, the extrusion mechanism includes a vertical frame 11, rollers 12, rectangular blocks 13, cylinders 14, a pitch-changing assembly 15, and a motor 16. There are two sets of vertical frames 11 and rollers 12, with the two sets of vertical frames 11 symmetrically arranged at both ends of the rollers 12. The first set of rollers 12 is rotatably mounted on the vertical frame 11 at both ends. There are two sets of rectangular blocks 13, symmetrically and slidably mounted on the vertical frame 11. The second set of rollers 12 is rotatably mounted on the rectangular blocks 13 at both ends. The vertical frame 11 is equipped with a motor frame 111 and a keyway 112. The second set of rollers 12 rotates at both ends. It is slidably mounted on the keyway 112. The cylinder 14 is positioned between the rectangular block 13 and the vertical frame 11. The cylinder 14 extends and retracts to adjust the distance between the two sets of rollers 12 to accommodate paper towels of different thicknesses. One set of motors 16 corresponds to one set of vertical frames 11. The motors 16 are fixedly mounted on the motor frame 111. There are two sets of pitch-changing components 15, one set of which corresponds to one set of vertical frames 11. The pitch-changing component 15 includes two sets of main gears 151, driven gears 152, transmission gears 153, and two sets of connecting rods 154. One set of main gears 151 corresponds to one set of rollers 12. The main gear 151 is fixedly installed at the ends of the two sets of rollers 12. The first set of main gears 151 is fixedly installed on the output shaft of the motor 16. The motor 16 drives the first set of main gears 151 to rotate, and the first set of main gears 151 drives the first set of rollers 12 to rotate. The driven gear 152 is rotatably installed on the vertical frame 11. The driven gear 152 meshes with the first set of main gears 151, and the first set of main gears 151 drives the driven gear 152 to rotate. The first ends of the two sets of connecting rods 154 are rotatably installed on the transmission gear 153, and the second end of one set of connecting rods 154 is connected to the driven gear 152. The second end of the other connecting rod 154 is rotatably mounted to the second set of main gears 151. The driven gear 152 meshes with the transmission gear 153, and the transmission gear 153 meshes with the second set of main gears 151. When the driven gear 152 rotates, it drives the transmission gear 153 to rotate. The transmission gear 153 drives the second set of rollers 12 to rotate through the second set of main gears 151. The two sets of rollers 12 rotate in opposite directions. When the second set of rollers 12 slides on the keyway 112 of the vertical frame 11, it changes the distance between the two sets of rollers 12 without affecting their rotation.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 11 , Figure 12 , Figure 13 , Figure 15As shown, each set of rollers 12 is provided with multiple sets of embossing mechanisms. Two sets of axial grooves 121 are symmetrically arranged on the rollers 12. Multiple sets of adjustment holes 122 are provided on the axial grooves 121. The embossing mechanism includes a ring frame 2 and two pairs of adjustment components. The ring frame 2 is provided with a protrusion 21. The ring frame 2 is slidably mounted on the axial groove 121 of the roller 12 through the protrusion 21. A cavity 22 is provided inside the protrusion 21. The adjustment components are located inside the cavity 22 and between the protrusion 21 and the axial groove 121. Two pairs of adjustment components are symmetrically arranged on each set of ring frames 2. The two pairs of adjustment components make the position of the ring frame 2 on the roller 12 more stable. The adjustment assembly includes an adjustment rod 41, a rocker arm 42, an adjustment column 43, and an adjustment spring 44. The adjustment rod 41 is slidably mounted on the protrusion 21. The adjustment rods 41 of each pair of adjustment assemblies are coaxial, and when the adjustment rods 41 of each pair of adjustment assemblies are working, the sliding directions of the adjustment rods 41 are opposite. There are two sets of rocker arms 42 and two sets of adjustment columns 43, with one set of rocker arms 42 corresponding to one set of adjustment columns 43. Limiting holes 212 are symmetrically provided on both sides of the protrusion 21. The two sets of adjustment columns 43 are symmetrically slidably mounted on the limiting holes 212 of the protrusion 21. A pin seat 411 is provided at the end of the adjustment rod 41, and the rocker arm 42 is positioned between the pin seat 411 and the adjustment column 43. One end of rod 42 is rotatably connected to pin seat 411, and the other end of rocker arm 42 is rotatably connected to adjusting column 43. A spring plate 211 is provided inside the protrusion 21, and an adjusting spring 44 is located between the spring plate 211 and pin seat 411. Pressing the adjusting rod 41 of each pair of adjusting components causes the two sets of adjusting rods 41 to move towards each other. The adjusting spring 44 is compressed, causing the rocker arm 42 to move towards the spring plate 211. The rocker arm 42 drives the two sets of adjusting columns 43 to move towards each other, and the two sets of adjusting columns 43 move closer to the axis of the adjusting rod 41. Multiple sets of adjusting holes 122 are symmetrically arranged on both sides of the axial groove 121 of roller 12. The adjusting holes 122 contact and engage with the adjusting columns 43. When the force applied to the adjusting rod 41 of each pair of adjusting components is released, the adjusting rod 41 of each pair of adjusting components is pushed to move in the opposite direction under the elastic action of the adjusting spring 44, pushing the two sets of adjusting columns 43 to move away from the axis of the adjusting rod 41. The adjusting column 43 slides on the limiting hole 212 until the adjusting column 43 contacts and engages with the adjusting hole 122. The adjusting rod 41 and the adjusting column 43 both stop moving, and the position of the ring frame 2 is fixed. By changing the distance between adjacent ring frames 2 through the adjusting components, the distance between adjacent embossing mechanisms and the number of embossing mechanisms are changed, thereby changing the embossing distance of the paper towel and changing the length of the formed paper towel.

[0034] like Figure 4 , Figure 5 , Figure 10 , Figure 14 , Figure 15As shown, the embossing mechanism also includes multiple sets of patterned arc plates 3, multiple sets of baffles 5, and multiple sets of positioning components. Each set of baffles 5 corresponds to a set of patterned arc plates 3, and the patterned arc plates 3 are slidably mounted on the shaft rail of the ring frame 2. Each set of baffles 5 corresponds to a set of positioning components. The ring frame 2 is provided with arc rails 23 and positioning grooves 24. Each set of arc rails 23 corresponds to a set of baffles 5, and the baffles 5 are slidably mounted on the arc rails 23. Each set of positioning grooves 24 corresponds to a set of positioning components. The positioning components include a positioning rod 61, a positioning block 62, and a positioning spring 63. The positioning rod 61 is slidably mounted on the baffle 5, and the positioning block 62 is fixedly mounted on the end of the positioning rod 61. The positioning block 62 is slidably mounted on the baffle 5. The positioning spring 63 is located inside the spring hole 51 and between the positioning block 62 and the spring hole 51. The positioning spring 63 is slidably mounted on the positioning rod 61. The positioning block 62 is in contact with the positioning groove 24. When the positioning block 62 and the positioning groove 24 are engaged, the baffle 5 closes the shaft rail of the ring frame 2, fixing the patterned arc plate 3 on the ring frame 2. Pulling the positioning rod 61 outward compresses the positioning spring 63, causing the positioning block 62 to move outward from the positioning groove 24, breaking the engagement between the positioning block 62 and the positioning groove 24. The positioning rod 61 pushes the baffle 5 to slide on the arc rail 23, breaking the restriction on the patterned arc plate 3, and the patterned arc plate 3 can be removed.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 11 As shown, the patterns on the patterned arc plates 3 are different. Depending on the different patterns on the patterned arc plates 3, the combination of multiple sets of patterned arc plates 3 on the ring frame 2 can be changed to perform various pattern combinations for embossing. If the patterns on the patterned arc plates 3 are the same, the width of the tissue embossing can be changed. Depending on the thickness of the tissue, single-sided embossing or double-sided embossing can be performed. When the tissue is thin, single-sided embossing is performed, and the patterns on the patterned arc plates 3 on one set of rollers 12 are freely combined, while the patterned arc plates 3 on the other set of rollers 12 have no patterns. If the tissue is thick, double-sided embossing is performed. When the combination of patterned arc plates 3 on the two sets of rollers 12 is the same, the tissue is embossed on both sides in the same way. When the combination of patterned arc plates 3 on the two sets of rollers 12 is different, the tissue is embossed on both sides in different ways. The combination methods are diverse, and the embossing efficiency is improved.

[0036] Working principle: Adjust the distance between the two sets of rollers 12 according to the thickness of the paper towel, start the cylinder 14, the cylinder 14 extends and retracts, driving the rectangular block 13 to slide on the vertical frame 11. The rectangular block 13 drives the second set of rollers 12 to slide on the vertical frame 11, so that the distance between the two sets of rollers 12 is adapted to the thickness of the paper towel when the embossing mechanism is installed.

[0037] Based on the thickness of the tissue paper, determine the combination of the pattern arc plates 3 on each set of embossing mechanisms. When the tissue paper is thin, single-sided embossing is performed, and the patterns on the pattern arc plates 3 on one set of rollers 12 are freely combined, while the pattern arc plates 3 on the other set of rollers 12 have no patterns. If the tissue paper is thick, double-sided embossing is performed. When the combination of pattern arc plates 3 on the two sets of rollers 12 is the same, the tissue paper is embossed on both sides in the same way. When the combination of pattern arc plates 3 on the two sets of rollers 12 is different, the tissue paper is embossed on both sides in different ways. Based on the width of the tissue paper, different pattern arc plates 3 are installed on the ring frame 2. Disengage the positioning block 62 from the positioning groove 24, and disconnect the baffle 5 from the shaft rail of the ring frame 2. In the closed state, the positioning spring 63 of the positioning component is in a compressed state; the limiting block 31 of the patterned arc plate 3 is slidably installed on the shaft rail of the ring frame 2, the positioning rod 61 is pushed, and the baffle 5 is driven to slide on the arc rail 23 of the ring frame 2 until the positioning block 62 is coaxial with the positioning groove 24. The force applied to the positioning rod 61 is disconnected, and under the elastic action of the positioning spring 63, the positioning block 62 is pushed to slide into the positioning groove 24. The positioning block 62 and the positioning groove 24 are engaged. At this time, the baffle 5 closes the shaft rail of the ring frame 2, and the patterned arc plate 3 is fixed. Repeat the above steps to make different combinations of the patterned arc plates 3 on the ring frame 2 and fix the patterned arc plates 3.

[0038] Depending on the length of the tissue paper, different numbers of embossing mechanisms are installed. For example, to cut the tissue paper into three pieces, three embossing mechanisms are needed; to cut it into five pieces, five embossing mechanisms are needed. Squeezing the adjusting rods 41 of the two pairs of adjusting components on the embossing mechanism causes each pair of adjusting rods 41 to move towards each other, compressing the adjusting spring 44. This compresses the rocker arm 42, causing it to move towards the spring plate 211. The rocker arm 42 then drives the two sets of adjusting columns 43 to move towards each other, causing the two sets of adjusting columns 43 to move closer to the axis of the adjusting rod 41, thus sliding the protrusion 21 onto the paper. Mounted on the axial groove 121, the target position of the embossing mechanism is determined as needed. After the embossing mechanism moves to the target position, the force applied to the adjusting rod 41 of each pair of adjusting components is disconnected. Under the elastic action of the adjusting spring 44, the adjusting rod 41 of each pair of adjusting components is pushed to move in the opposite direction, pushing the two sets of adjusting columns 43 to move away from the axis of the adjusting rod 41. The adjusting column 43 slides on the limiting hole 212 until the adjusting column 43 contacts and engages with the adjusting hole 122. The adjusting rod 41 and the adjusting column 43 both stop moving, and the position of the ring frame 2 is fixed.

[0039] After the embossing mechanism is installed, the tissue paper to be embossed is passed between the two sets of rollers 12. The motor 16 is started, and the motor 16 drives the first set of main gears 151 to rotate. The first set of main gears 151 drives the first set of rollers 12 to rotate. The first set of main gears 151 drives the driven gear 152 to rotate. When the driven gear 152 rotates, it drives the transmission gear 153 to rotate. The transmission gear 153 drives the second set of rollers 12 to rotate through the second set of main gears 151. The two sets of rollers 12 rotate in opposite directions. The rollers 12 drive the embossing mechanism to rotate. When the pattern arc plate 3 on the embossing mechanism rotates, it embosses the tissue paper.

[0040] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
