Technical Field
[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a non-woven fabric printing roller component. Background Art
[0002] Non-woven fabric, also known as non-woven fabric, is a kind of fabric that does not require spinning and weaving. It is just that the textile short fibers or filaments are oriented or randomly arranged to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is not made of yarns interwoven and knitted together one by one, but the fibers are directly bonded together by physical methods. Non-woven fabrics break through the traditional textile principles and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple sources of raw materials.
[0003] In the production process of non-woven fabrics, it is generally necessary to perform embossed extrusion printing operations. The printing and shaping operations can produce various patterns on the non-woven fabrics. On the one hand, it can improve the physical bonding effect of the fibers, and on the other hand, it can make the non-woven fabrics have unique visual effects and feel. It is an important process in the production process of non-woven fabrics.
[0004] In the existing non-woven fabric production, printing rollers are usually used. Since the existing non-woven fabric printing rollers use flexible mesh structures, it is easy to have uneven printing. The main manifestation is the distortion or loss of roundness of the printing roller in the middle, which causes uneven printing of the non-woven fabric. After working for a long time, the distortion will be gradually magnified, and eventually cause unstable equipment operation and defective fabrics. Summary of the invention

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0007] A non-woven fabric printing roller shaft component comprises a printing roller and a pressure roller arranged above the printing roller, the non-woven fabric is transported between the printing roller and the pressure roller, the printing roller is a hollow structure, and its surface is a porous pattern structure, a support roller is arranged at the top of the interior of the printing roller, the upper end of the support roller is arranged in contact with the inner wall of the printing roller, and a balancing roller is arranged in contact with the pressure roller, and the balancing roller, the pressure roller, the printing roller and the support roller are arranged in a vertical alignment from top to bottom.
[0008] Furthermore, the outer rings of the pressure roller and the support roller have a rubber structure to achieve a certain elasticity.
[0009] Furthermore, the rubber structure of the pressure roller is larger than the rubber structure of the support roller.
[0010] Furthermore, the printing roller comprises a sheet barrel-shaped body and end portions arranged at both ends of the body, wherein the end portions are provided with a circle of slots, and the slots are used to insert and install the two ends of the body at the end portions.
[0011] Furthermore, a group of guide wheels are arranged below the end portion, and the guide wheels can carry the printing roller and keep it in a balanced rotation state.
[0012] Furthermore, a mounting plate is arranged at the outer end of the printing roller, and the mounting plate has an upper slide groove and a lower slide groove. The two ends of the pressure roller and the balance roller are installed in cooperation with the upper slide groove through bearings and slider structures, and the two ends of the support roller are installed in cooperation with the lower slide groove through bearings and slider structures.
[0013] Furthermore, an upper cylinder is connected to the outer end of the balancing roller, and the upper cylinder can adjust the downward or upward pressure of the balancing roller, and then apply force to the pressure roller. A lower cylinder is connected to the outer end of the supporting roller, and the lower cylinder can adjust the upward or downward pressure of the supporting roller.
[0014] Compared with the existing technology, this solution has the following advantages:
[0015] The present invention relates to a non-woven fabric printing roller shaft component, in which a balanced printing balance structure is formed by a balance roller, a pressure roller, a printing roller and a support roller structure aligned in a vertical direction from top to bottom, wherein the upward support force of the support roller and the downward pressure of the pressure roller are used to implement the printing operation of the non-woven fabric at the printing roller, and the balance roller is used to prevent the pressure roller from twisting and deforming, so it is particularly suitable for the printing processing operation of large-format non-woven fabrics;
[0016] The outer rings of the pressure roller and the support roller have a rubber structure, which has a certain elasticity and can ensure the stability of the printing operation. The rubber structure of the pressure roller is larger than that of the support roller, so the support roller can play a better supporting and elastic role inside the printing roller.
[0017] The printing roller of this scheme only participates in the printing operation without bearing its own printing pressure, so its pattern can be more varied, the pattern cycle can be larger and more natural, and the stability of its operation is improved. It can adapt to large-format printing operations of multiple replicated patterns, greatly improve the stability of its printing operation, and reduce its maintenance cost.

[0026] refer to Figures 1 to 5 A non-woven fabric printing device includes a printing roller shaft component and a blowing component. The printing roller shaft component includes a printing roller 1 and a pressure roller 11 arranged above the printing roller. The non-woven fabric is transported between the printing roller 1 and the pressure roller 11. The printing roller 1 is a hollow structure with a porous pattern structure on its surface, which is used to realize embossing printing operation on the non-woven fabric under extrusion.
[0027] The printing roller 1 includes a thin barrel-shaped body 101 and end portions 102 arranged at both ends of the body. The end portions 102 have a circle of slots 103, and the slots 103 are used to insert and install the two ends of the body 101 to the end portions 102. When necessary, a corresponding screw structure can be provided so that the body 101 and the end portions 102 are firmly installed, thereby constructing a complete printing roller 1. In some cases, to replace different printing patterns, only the corresponding body 101 needs to be replaced without replacing the entire printing roller 1. In some embodiments, the porous thin sheet-shaped body 101 is combined and installed to reduce its production difficulty and improve its use efficiency.
[0028] A group of guide wheels 104 are arranged below the end portion 102. The guide wheels 104 can carry the embossing roller 1 and keep it in a balanced rotation state.
[0029] A supporting roller 13 is arranged at the top of the inside of the printing roller 1, and the upper end of the supporting roller 13 is arranged in contact with the inner wall of the printing roller 1, and a balancing roller 13 is arranged in contact with the top of the pressure roller 11, wherein the outer rings of the pressure roller 11 and the supporting roller 13 have rubber structures to achieve a certain elasticity, and at the same time, the rubber structure of the pressure roller 11 is larger than the rubber structure of the supporting roller 13, so under the clamping operation of the pressure roller 11 and the supporting roller 13, the precise printing operation of the non-woven fabric at the printing roller 1 can be achieved, and the balancing roller 13 is used to maintain a balancing effect on the pressure roller 11, which can be supported by metal materials and has good structural strength as a whole, and is used to fit the pressure roller 11 from directly above to prevent the pressure roller 11 from being twisted or out of round.
[0030] In this embodiment, the balancing roller 13, the pressure roller 11, the printing roller 1 and the supporting roller 13 are arranged in a vertical alignment from top to bottom. In order to better realize pressure regulation and ensure the stability of its operation, mounting plates 14 are arranged on both sides thereof. The mounting plates 14 have an upper slide groove 15 and a lower slide groove 16. The two ends of the pressure roller 11 and the balancing roller 13 are installed in cooperation with the upper slide groove 15 through a bearing and a slider structure, and realize vertical up and down displacement within the range and limit of the upper slide groove 15. The two ends of the supporting roller 13 are also installed in cooperation with the lower slide groove 16 through a bearing and a slider structure.
[0031] In order to achieve pressure regulation of non-woven fabric printing extrusion, an upper cylinder 18 is connected to the outer end of the balancing roller 12, and the upper cylinder 18 can adjust the downward or upward pressure of the balancing roller 12, and then apply force to the pressure roller 11, and a lower cylinder 19 is connected to the outer end of the supporting roller 13, and the lower cylinder 19 can adjust the upward or downward pressure of the supporting roller 13. Finally, through the joint force and pressure regulation operation of the upper cylinder 18 and the lower cylinder 19, the precise printing operation of the non-woven fabric at the printing roller 1 is achieved, and the stability of its long-term printing work is achieved.
[0032] refer to Figures 6 to 8 The blowing component includes an outer blowing mechanism 2 and an inner blowing mechanism 4. The outer blowing mechanism 2 is arranged on the outside of the printing roller 1 in the material feeding direction, and implements an operation of blowing air obliquely downward on the surface of the printing roller 1. The inner blowing mechanism 4 is arranged inside the printing roller 1, close to the outer blowing mechanism 2, and implements an operation of blowing air from the inside to the outside through the printing holes of the printing roller 1.
[0033] The external blowing component 2 includes a horizontally arranged guide roller 21 and a balance rod 22 arranged on the outside of the printing roller 1 in the material feeding direction. A mounting block 23 is arranged on the guide roller 21 and the balance rod 22. A motor 20 is arranged at one end of the guide roller 21. The motor 20 can drive the guide roller 21 to rotate, and through its screw structure, drive the mounting block 23 to realize horizontal reciprocating translational motion on the outside of the printing roller 1.
[0034] The internal blowing mechanism 4 has a driving structure similar to that of the external blowing component 2, which agrees with the arrangement of guide rollers, balance bars and mounting blocks. The guide roller and the guide roller 21 of the external blowing component are driven by pulleys and belts, and driven by the motor 20 to achieve synchronous rotation of the two, thereby achieving synchronous reciprocating motion of the two mounting blocks inside and outside the printing roller 1.
[0035] In some embodiments, the guide roller 21 is a reciprocating screw structure, that is, its surface has forward threads and reverse threads, and the forward threads and reverse threads at both ends have a smooth arc transition. Therefore, when the motor 20 drives the guide roller 21 at a constant speed, its matching mounting block 23 can switch between the two threads and realize continuous reciprocating motion.
[0036] A first blowing head 24 is arranged on the mounting block 23. The first blowing head 24 has a flat air outlet. The rear end of the first blowing head 24 is connected to an air duct 25 and a fan. Under the action of the fan and the air duct 25, the first blowing head 24 can continuously perform a positive pressure blowing operation. The first blowing head 24 blows air in an oblique downward direction toward the surface of the printing roller 1 to remove fibers and fiber clumps accumulated on the surface of the oiling roller 1.
[0037] In some embodiments, the first blowing head 24 is hingedly connected to the mounting block 23 through the mounting frame 26, and an angle adjustment mechanism is arranged between the two. The mechanism is adjusted to a screw 27 and an adjustment nut 28 structure, wherein the rear end of the adjustment screw 27 is in a rotational connection with the mounting frame 26, so the adjustment nut 28 can be used to adjust the angle between the mounting frame 26 and the first blowing head 24 and the mounting block 23, thereby adjusting the blowing angle of the first blowing head 24 relative to the surface of the printing roller 1. As a preferred solution, the first blowing head 24 should blow in the tangent direction of the outer surface of the printing roller 1, and blow in the opposite direction of the rotation of the printing roller 1 in real time.
[0038] At the inner blowing mechanism 4, a second blowing head 41 is arranged. The second blowing head 41 is also connected to a blower and an air duct, and also has a flat air outlet with the same size as the first blowing head 41, but it is in a fixed state and blows air in a horizontal outward direction, and always keeps in sync with the first blowing head 24.
[0039] In some embodiments, a collecting frame 3 is arranged below the mounting block 23 , and the collecting frame 3 is used to collect the fibers and fiber clusters separated from the surface of the printing roller 1 .
[0040] The front end of the lower plate of the collecting frame 3 is arranged close to the outer wall of the printing roller 1, and the rear plate of the collecting frame 3 is provided with a bin door 31, which is used for the operator to clean the fiber clusters inside it when appropriate. A filter screen 32 is provided on the upper part of the rear plate of the collecting frame 3, which is used for filtering and isolating, and realizes that under the common blowing airflow of the first blowing head 24 and the second blowing head 41, the fibers and fiber clusters are collected inside the collecting frame 3 as much as possible.
[0041] In order to perform a comprehensive and complete blowing cleaning operation on the surface of the embossing roller 1, the first blowing head 24 and the second blowing head 41 synchronously reciprocate once, and the reciprocating distance is slightly greater than the circumference of the embossing roller 1. Specifically, when the first blowing head 24 and the second blowing head 41 blow air on the embossing roller 1, the blowing action is about 1 / 24 of the circumference in the cross-sectional direction. Then, the first blowing head 24 and the second blowing head 41 reciprocate once, and the starting point is ( Figure 8 The first point is point A, the second point is point B, and the distance between the two points AB is preferably 1 / 48 of the circumference of the printing roller 1. Therefore, through such a design, after multiple consecutive blowing operations, the surface of the printing roller 1 can always be fully and completely blown, ensuring the cleanliness of the surface of the printing roller 1.
[0042] In summary, the present invention provides a non-woven fabric printing device, in which a balanced printing balance structure is formed by balancing rollers, pressure rollers, printing rollers and support rollers aligned vertically from top to bottom in the printing roller shaft component, wherein the upward support force of the support roller and the downward pressure of the pressure roller are used to implement the printing operation of the non-woven fabric at the printing roller, and the balancing roller is used to prevent the pressure roller from twisting and deforming, so it is particularly suitable for the printing processing operation of large-format non-woven fabrics;
[0043] The printing roller of this scheme only participates in the printing operation without bearing its own printing pressure, so its pattern can be more varied, the pattern cycle can be larger and more natural, and its operation stability is improved, it can adapt to large-format printing operations of multiple replicated patterns, and reduce its maintenance cost;
[0044] This solution adopts the structure of an external air blowing mechanism and an internal air blowing mechanism to implement the blowing operation, wherein the external air blowing mechanism adopts an oblique blowing method to blow and remove dust from the outer surface of the printing roller, while the internal air blowing mechanism has a horizontal outward blowing structure, which greatly improves the efficiency of the printing roller in removing fiber clusters, and can prevent the accumulation of fibers or fiber patterns at the pattern of the printing roller, thereby improving the stability of non-woven fabric production;
[0045] A collecting frame is arranged under the first blowing head to collect the fiber clumps blown off from the printing roller, which can prevent the fiber clumps and fibers from running around in the workshop and ensure the neatness of the workshop;
[0046] This solution adopts a reciprocating screw structure to implement the synchronous reciprocating motion of the first blowing head and the second blowing head, and can ensure that the reciprocating motion is slightly larger than the circumference of the printing roller, so that the printing roller can be fully blown, thereby improving the stability of the system operation.
