DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0025] See also Figure 1-Figure 7 In an embodiment of the utility model, a dislocated distributed single-specification four-sided embossing mechanism comprises a frame 1 and an embossing roller group arranged on the frame 1; wherein, the embossing roller group is provided with two groups on the frame 1, and the two groups of the embossing roller groups are symmetrically arranged, and the embossing roller group comprises: a flower roller 2, a guide roller 4 and a guide roller 8, the paper towel to be processed bypasses the guide roller 8 and passes between the flower roller 2 and the guide roller 4, the guide roller 4 is located on the upper part of the flower roller 2 and abuts against the flower roller 2, and the flower roller 2 can be driven to rotate by a driving motor 6 installed on the side of the frame 1, and the flower roller 2 is provided with a pattern; a distributed support structure is provided on the frame 1, distributed along the axial direction of the flower roller 2, and cooperates with the flower roller 2, and the distributed support structure can move toward the flower roller 2 to support the paper towel passing through the flower roller 2.

[0026] It should be further explained that the guide roller 4 has the function of guiding, limiting and fixing the paper towel to achieve the effect of pre-pressing. In the specific implementation, the patterns on the two flower rollers 2 on the frame 1 are different to achieve the pressing of different patterns. The flower roller 2 is detachable so that it can be replaced according to the processing requirements. The paper towel after embossing is then cross-cut and longitudinally cut to form a single packaged paper towel; secondly, the distributed support structure is arranged in multiple sections and is equidistantly distributed along the axial direction of the flower roller 2. When working, the distributed support structure will move toward the flower roller 2 to provide a stable support surface for the flower roller 2, ensuring that the flower roller 2 can apply pressure evenly, thereby ensuring the uniformity and consistency of the embossing effect. In addition, during the embossing process, the distributed support structure works together with the flower roller 2. By adjusting the gap between the two, the embossing depth and effect of the paper can be accurately controlled.

[0027] Please refer again Figure 2 , Figure 5 , Figure 6 as well as Figure 7 The distributed support structure includes a square tube 10 mounted on the frame 1 and a plurality of bottom rollers 3 movably mounted on the square tube 10. The plurality of bottom rollers 3 are equidistantly distributed along the length direction of the square tube 10 and connected to an inflatable drive assembly mounted on the square tube 10. The inflatable drive assembly can cause the bottom roller 3 to swing toward the pattern roller 2. In detail, the present application replaces the existing integrated roller body setting by arranging and distributing a plurality of bottom rollers 3 equidistantly along the axial direction of the pattern roller 2, thereby improving the accuracy of the cooperation between the bottom roller 3 and the pattern roller 2, and making the embossed pattern more uniform and consistent in depth.

[0028] The inflatable drive assembly includes a mounting frame arranged on the square tube 10 and a booster matched with the mounting frame. The bottom roller 3 is arranged on the mounting frame, and the booster can cause the mounting frame to drive the bottom roller 3 to swing toward the flower roller 2. The mounting frame includes two mounting arms 11 fixed on the square tube 10, a roller 14 rotatably mounted between the two mounting arms 11, and an assembly plate 12 fixedly connected to the roller 14. The bottom roller 3 is rotatably mounted on the assembly plate 12, and the assembly plate 12 is also connected to a buffer assembly arranged on the square tube 10. The booster includes an airbag 16 arranged on the square tube 10, and the airbag 16 is provided with an inflation port, and the inflation port is connected to an inflation pump arranged in the square tube 10. The inflation pump can inflate the airbag 16 through the inflation port to expand the airbag 16 and push the assembly plate 12 to swing.

[0029] During specific implementation, the air pump inflates air into the airbag 16 through the inflation port, causing the airbag 16 to expand. Therefore, during the expansion of the airbag 16, pressure is applied to the assembly plate 12, causing the assembly plate 12 to drive the bottom roller 3 to deflect, so that the bottom roller 3 moves toward the flower roller 2, and pressure is applied to the paper towel passing through the flower roller 2 to ensure the embossing effect. In general, the present application improves the original integrated roller body setting into a plurality of bottom rollers 3 equidistantly distributed along the axial direction of the flower roller 2, and the clamping force between the bottom roller 3 and the flower roller 2 is achieved by using the expansion of the airbag 16. Compared with the existing springs, the distributed setting can offset the deformation caused by the left and right fluctuations of the springs.

[0030] The buffer assembly includes a hydraulic buffer 13 disposed on the square tube 10 , and a collision-receiving head of the hydraulic buffer 13 abuts against the assembly plate 12 .

[0031] To elaborate, the oil pressure buffer 13 is an application of the prior art. Specifically, its working principle is based on the hydraulic damping mechanism. When an object is impacted, the kinetic energy is transferred to the piston through the impact head and the axis, pushing the piston to move to the other end. The movement of the piston squeezes the hydraulic oil in the inner tube, and the hydraulic oil is squeezed out from the oil drain hole between the piston and the axis and enters the oil chamber. As the piston continues to move, the hole on the surface of the inner tube is blocked, and the piston resistance increases, thereby consuming a large amount of kinetic energy and achieving a buffering effect. When the external force disappears, the return spring bounces the piston back to its original position, completing the working cycle.

[0032] In the present application, the oil pressure buffer 13 is of the AirTac brand, and its setting can play a buffering role when the bottom roller 3 and the flower roller 2 are in close contact, thereby preventing the bottom roller 3 and the flower roller 2 from being too closely contacted, and ensuring that the paper towels can pass normally at a uniform speed.

[0033] Please refer again Figure 5 , Figure 6 as well as Figure 7 A felt cloth 9 is also installed on the assembly plate 12, and the felt cloth 9 is in contact with the outer wall of the bottom roller 3, and the felt cloth 9 is connected to an external oil pump through an oil pipe, and the oil pump is used to transport lubricating oil to the felt cloth 9 through the oil pipe; wherein a scraper 15 is also provided at the bottom of the assembly plate 12, and the scraper 15 is in contact with the outer wall of the bottom roller 3, and a long strip-shaped mounting hole is provided on the scraper 15.

[0034] During the operation of the mechanism, the scraper 15 can scrape off the paper towel dust adhering to the outer wall of the bottom roller 3, thereby ensuring the cleanliness of the components for a long time and avoiding excessive accumulation of paper towel dust and causing adverse effects on the embossing effect. The installation hole of the scraper 15 is in the shape of a long strip, so that the scraper 15 can control the distance from the bottom roller 3 during installation, which is convenient for translation. Secondly, in order to improve the problem of paper towel dust adhering to the bottom roller 3 from the source, during the operation of the mechanism, the external oil pump can deliver lubricating oil to the felt cloth 9 through the oil pipe in a timely and quantitative manner, thereby realizing the function of providing lubricating oil to the bottom roller 3, thereby avoiding the bottom roller 3 from being too dry and easily adhering to paper towel dust.

[0035] The displaced distributed single-specification four-side embossing mechanism further includes a cleaning mechanism disposed on the frame 1 , and the cleaning mechanism is used to clean paper towel dust adhered to the pattern roller 2 .

[0036] Please refer again Figure 1 , Figure 3 as well as Figure 4The cleaning mechanism includes a cleaning roller 5 rotatably mounted on the frame 1, the outer periphery of the cleaning roller 5 is provided with cleaning fluff in contact with the outer wall of the flower roller 2, and a dust collecting plate 7 is also installed on the frame 1, and the dust collecting plate 7 is used to receive the paper towel dust swept by the cleaning fluff.

[0037] During the operation of the mechanism, the cleaning roller 5 can use the cleaning fluff thereon to clean the outer wall of the pattern roller 2, thereby avoiding the problem of excessive paper towel dust accumulating in the pattern of the pattern roller 2 after the mechanism has been running for a long time, thereby causing poor embossing effect.
