Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a device for removing fiber clusters from a shaping roller in non-woven fabric processing. Background Art
[0002] Non-woven fabric, also known as non-woven cloth, is a fabric formed without the need for spinning and weaving. It is only formed by arranging textile staple fibers or filaments in a directional or random manner to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is not woven by interweaving and knitting individual yarns, but by directly bonding the fibers together physically. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple raw material sources.
[0003] During the production process of non-woven fabric, generally, embossing printing or shaping operations of embossed plates are required. The printing and shaping operations can produce various patterns on the non-woven fabric. On the one hand, it can improve the physical bonding effect of the fibers, and on the other hand, it can endow the non-woven fabric with unique visual effects and handfeel, which is an important process in the production process of non-woven fabric.
[0004] Special attention should be paid to the phenomenon of fiber cluster burrs in non-woven fabric production, that is, there are excess fibers remaining on the fabric surface. The remaining fibers mainly come from the surface of the extrusion roller. During the processing, it is easy to leave tiny fiber clusters on the surface of the extrusion roller. If not processed in time, these fiber clusters will entangle or adsorb fibers again, grow larger and larger, and eventually transfer to the non-woven fabric, forming a protrusion phenomenon, resulting in defective fabric. Summary of the Invention
[0005] The purpose of the utility model is to provide a device for removing fiber clusters from a shaping roller in non-woven fabric processing, which can reduce the phenomenon of fiber cluster burrs in non-woven fabric while ensuring stable production of non-woven fabric.
[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0007] A device for removing fiber clusters from a shaping roller in non-woven fabric processing includes an extrusion roller and a blowing component arranged on one side of the extrusion roller. A pressure roller is arranged above the extrusion roller, and the non-woven fabric is conveyed between the shaping roller and the pressure roller. The blowing component includes a guide roller arranged outside the feeding direction of the extrusion roller. An installation block is arranged on the guide roller in a matching manner, and a blowing head is arranged on the installation block. The blowing head has a flat air outlet, and the rear end of the blowing head is connected to an air guide pipe and a blower. The blowing head blows air obliquely downward towards the surface of the extrusion roller. The guide roller is a lead screw structure, and one end of it is connected to a motor.
[0008] Furthermore, the blowing head and the installation block are in a hinged structure, and an angle adjustment mechanism is arranged between the two.
[0009] Further, the adjusting mechanism includes an adjusting screw and an adjusting nut.
[0010] Further, a collection box is arranged below the mounting block, and the front end of the lower plate of the collection box is attached close to the outer wall of the squeezing roller.
[0011] Further, a bin door structure is provided on the rear plate of the collection box.
[0012] Further, a filter screen structure is provided on the upper part of the rear plate of the collection box.
[0013] Further, after the motor drives the guide roller to make a reciprocating motion once, the distance that the air blowing head travels at the starting point and the ending point is greater than the circumference of the squeezing roller.
[0014] Further, the guide roller is a reciprocating lead screw structure.
[0015] Adopting this solution, compared with the prior art, it has the following advantages:
[0016] For the fiber mass removing device of the shaping roller in the non-woven fabric processing of this solution, the squeezing roller is blown for dust removal by an oblique air blowing method, and a flat air outlet is designed. At the same time, the reciprocating air blowing head is implemented, which greatly improves the efficiency of removing fiber masses from the squeezing roller, and further improves the stability of non-woven fabric production;
[0017] A collection box is arranged below the air blowing head for collecting the fiber masses blown off from the squeezing roller, which can prevent the fiber masses and fibers from running around in the workshop and ensure the neatness of the workshop;
[0018] This solution uses a reciprocating lead screw structure to implement the reciprocating motion of the air blowing head, and can ensure that its reciprocation is slightly greater than the circumference of the squeezing roller. Therefore, it can ensure that the outer surface of the squeezing roller can be comprehensively blown, and thus improve the stability of the system operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figures 1 to 5 , a device for removing fiber clusters from a setting roller in non-woven fabric processing, including an extrusion roller 1 and a blowing component 2 arranged on one side of the extrusion roller. A pressure roller 11 is arranged above the extrusion roller 1. The non-woven fabric is conveyed between the setting roller 1 and the pressure roller 11 to achieve the setting operation. The blowing component 2 includes a horizontally arranged guide roller 21 and a balance rod 22 arranged outside the feeding direction of the extrusion roller. An installation block 23 is arranged in cooperation with 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 lead screw structure, drive the installation block 23 to achieve a horizontal reciprocating translational motion outside the setting roller 1.
[0025] In some embodiments, the guide roller 21 is a reciprocating lead screw structure, that is, its surface has a forward thread and a reverse thread, and the forward thread and the reverse thread are smoothly transitioned in an arc at both ends thereof. Therefore, when the motor 20 drives the guide roller 21 at a constant speed, the cooperating installation block 23 can switch between the two threads and achieve continuous reciprocating motion.
[0026] A blowing head 24 is arranged on the installation block 23. The blowing head 24 has a flat air outlet. The rear end of the blowing head 24 is connected to an air guide pipe 25 and a blower. Under the action of the blower and the air guide pipe 25, the blowing head 24 can continuously perform positive-pressure blowing operations. The blowing head 24 blows air obliquely downward toward the surface of the extrusion roller 1 to remove the fibers and fiber clusters accumulated on the surface of the oiling roller 1.
[0027] In some embodiments, the blowing head 24 and the installation block 23 are in a hinged structure through an installation frame 26, and an angle adjustment mechanism is arranged between the two. This mechanism is adjusted to a screw 27 and an adjustment nut 28 structure. The rear end of the adjustment screw 27 is rotatably connected to the installation frame 26. Therefore, by adjusting the adjustment nut 28, the angle between the installation frame 26 and the blowing head 24 relative to the installation block 23 can be adjusted, and further the blowing angle of the blowing head 24 relative to the surface of the setting roller 1 can be adjusted. As a preferred solution, the blowing head 24 should blow air in the tangential direction of the outer surface of the setting roller 1 and blow air in the opposite direction of the rotation of the setting roller 1 in real time.
[0028] In some embodiments, a collection box 3 is arranged below the installation block 23. The collection box 3 is used to collect the fibers and fiber clusters separated from the surface of the setting roller 1.
[0029] The front end of the lower plate of the collection box 3 is arranged close to the outer wall of the extrusion roller 1. A warehouse door 31 is provided on the rear plate of the collection box 3. The warehouse door is used for the operator to clean the fiber clusters inside at an appropriate time. A filter screen 32 is provided on the upper part of the rear plate of the collection box 3. The filter screen is used to play a role of filtering and isolation, and to make the fibers and fiber clusters be collected inside the collection box 3 as much as possible under the blowing air flow.
[0030] In order to perform a comprehensive and complete blowing and cleaning operation on the surface of the extrusion roller 1, when the reciprocating movement of the blowing head 24 is once, ensure that its reciprocation is slightly greater than the circumference of the extrusion roller 1. Specifically, when the blowing action of the blowing head 24 acts on the surface of the extrusion roller 1, in its cross-sectional direction, it is within a range of about 1 / 24 of the circumference. Then, when the blowing head 24 reciprocates once, its starting point is ( Figure 5 middle) point A, and the end point is point B, and the distance between points A and B is preferably 1 / 48 of the circumference of the extrusion roller 1. Therefore, through such a design, after continuous blowing operations for multiple times, the surface of the extrusion roller 1 can be subjected to a comprehensive and complete blowing operation, ensuring the cleanliness of the surface of the extrusion roller 1.
[0031] To sum up, for the fiber mass removal device of the shaping roller in the non-woven fabric processing of this solution, an inclined blowing method is adopted to perform a blowing and dust removal operation on the extrusion roller, and a flat-shaped air outlet design is adopted. At the same time, a reciprocating blowing head is implemented, which greatly improves the efficiency of fiber mass removal of the extrusion roller, and further improves the stability of non-woven fabric production;
[0032] A collection box is arranged below the blowing head to collect the fiber masses blown off from the extrusion roller, which can prevent the fiber masses and fibers from running around in the workshop and ensure the neatness of the workshop;
[0033] This solution adopts a reciprocating lead screw structure to implement the reciprocating movement of the blowing head, and can ensure that its reciprocation is slightly greater than the circumference of the extrusion roller. Therefore, it can ensure that the outer surface of the extrusion roller can be subjected to a comprehensive blowing operation, and thus improve the stability of the system operation.
