Description

Technical Field

[0001] The present disclosure relates to the technical field of non-woven fabric processing equipment, and particularly to a non-woven fabric slitter. Background Art

[0002] Non-woven fabrics are widely used due to their high strength, wide application fields, short production process, and relatively low comprehensive cost. However, during the manufacturing process, particulate matter residues often occur due to insufficient cleaning, which affects the quality. Traditional manual cleaning is costly and inefficient. Therefore, improving the cleaning efficiency in non-woven fabric production has become a key challenge.

[0003] After retrieval, it can be known that in the prior art, for example, patent CN202021399035.4 discloses an improved non-woven fabric printing and slitting machine, which includes a base, a printing box, and left and right sliding plates. The left part of the base is rotatably connected to a raw material roller through a first sliding module, and the right part of the base is rotatably connected to a winding roller through a second sliding module; during operation, the second servo reduction motor provides power, and finally drives the horizontal sliding plate to move relatively, quickly assembling the raw material roller and the winding roller. The operation is simple, and it is applicable to a wide range of non-woven fabric widths. Dye from the dye box is applied to the printing roller through a brush, and then printed on the non-woven fabric. At the same time, the cleaning roller rotates to clean contaminants such as fluff on the surface of the non-woven fabric, ensuring the printing quality. The fluff and the like fall into the waste collection box for easy cleaning. The blower blows air and discharges it through the air outlet to quickly dry the non-woven fabric, reducing the process time and improving the work efficiency. The above improved non-woven fabric printing and slitting machine still has the following defects in practical applications:

[0004] By rotating the cleaning roller to clean contaminants such as fluff on the surface of the non-woven fabric, the printing quality is ensured, and the fluff and the like fall into the waste collection box for easy cleaning. Cleaning with only one set cleaning roller set like this results in the inability to comprehensively clean both the front and back sides of the non-woven fabric, and the cleaning efficiency is low and the cleaning quality is poor. Summary of the Utility Model

[0005] In order to solve the problems existing in the above prior art, the purpose of the present disclosure is to provide a non-woven fabric slitter. Since the adjacent cleaning rollers are arranged at intervals with misalignment, when the non-woven fabric passes through the cloth guiding assembly, both its front and back sides can come into contact with the cleaning rollers, thereby realizing the simultaneous cleaning of both the front and back sides of the non-woven fabric and ensuring the comprehensiveness and thoroughness of the cleaning.

[0006] A non-woven fabric slitter described in the present disclosure includes a frame, and a feeding roll assembly, a cloth guiding assembly, a slitting assembly, and a winding roll assembly that are sequentially arranged on the frame along the movement track of the non-woven fabric;

[0007] The cloth guiding assembly includes a plurality of cloth guiding rollers and at least two cleaning rollers disposed between the plurality of cloth guiding rollers, and adjacent cleaning rollers are arranged at intervals and offset, so that both the front and back sides of the non-woven fabric can contact the cleaning rollers.

[0008] Preferably, the axial center distance between two adjacent cleaning rollers is 38 cm to 42 cm.

[0009] Preferably, a dust removal non-woven fabric is provided on the outer surface of the cleaning roller.

[0010] Preferably, the dust removal non-woven fabric is coated with an adhesive solution, and the adhesive solution is one of an epoxy resin adhesive solution, a urethane adhesive solution or a polyvinyl acetate adhesive solution.

[0011] Preferably, the upper winding assembly includes an upper cloth air shaft, and the upper cloth air shaft is used to guide the non-woven fabric to the cloth guiding assembly.

[0012] Preferably, the cloth guiding assembly further includes an expanding roller, and the expanding roller is disposed near the slitting assembly, and the expanding roller is used to adjust the width of the non-woven fabric.

[0013] Preferably, the slitting assembly includes a cutting guide roller and a slitting mechanism, the cutting guide roller is adjacent to the slitting mechanism, and the slitting mechanism is used to cut the non-woven fabric passing through the cutting guide roller.

[0014] Preferably, the lower winding assembly includes a main driving wheel, a sub-driving wheel and a lower winding air shaft, and the lower winding air shaft is disposed between the main driving wheel and the sub-driving wheel.

[0015] The advantages of the non-woven fabric slitting machine described in the present disclosure are as follows:

[0016] A non-woven fabric slitting machine of the present disclosure includes a frame, and an upper winding assembly, a cloth guiding assembly, a slitting assembly and a lower winding assembly which are sequentially arranged on the frame along the movement track of the non-woven fabric; the cloth guiding assembly includes a plurality of cloth guiding rollers and at least two cleaning rollers disposed between the plurality of cloth guiding rollers, and adjacent cleaning rollers are arranged at intervals and offset, so that both the front and back sides of the non-woven fabric can contact the cleaning rollers. Due to the offset arrangement of adjacent cleaning rollers, when the non-woven fabric passes through the cloth guiding assembly, both its front and back sides can contact the cleaning rollers, thereby realizing the simultaneous cleaning of both sides of the non-woven fabric, ensuring the comprehensiveness and thoroughness of the cleaning; the offset cleaning rollers can more effectively remove impurities and residues on the surface of the non-woven fabric, reducing subsequent processing problems caused by incomplete cleaning; the clean non-woven fabric can reduce the wear of the slitting tool and equipment during the slitting process, helping to extend the service life of the equipment; and the thoroughly cleaned non-woven fabric is less likely to have defects caused by impurities or residues in subsequent processing, thereby improving the overall quality of the product.

[0031] As Figure 1 - Figure 2 shown, a non-woven fabric slitting machine described in the present disclosure includes a frame 10, and an upper winding assembly, a fabric guiding assembly, a slitting assembly, and a lower winding assembly that are sequentially arranged on the frame along the movement track of the non-woven fabric;

[0032] The fabric guiding assembly includes a plurality of fabric guiding rollers 20 and at least two cleaning rollers 30 arranged between the plurality of fabric guiding rollers 20, and the adjacent cleaning rollers 30 are arranged at intervals and offset, so that both the front and back sides of the non-woven fabric can contact the cleaning rollers 30; specifically, when the non-woven fabric passes through the fabric guiding assembly, it first passes through the fabric guiding rollers 20 and then through the cleaning rollers 30. When passing through the two cleaning rollers 30, it is wound in an S shape so that both the front and back sides of the non-woven fabric can be comprehensively cleaned of fine particles and dust, and finally it is combed and formed by the fabric guiding rollers 20; in this embodiment, the number of cleaning rollers 30 is selected to be two;

[0033] Due to the staggered arrangement of adjacent cleaning rollers 30 in the above structure, when the non-woven fabric passes through the cloth guiding assembly, both the front and back sides of the non-woven fabric can come into contact with the cleaning rollers 30, thus realizing the simultaneous cleaning of both sides of the non-woven fabric and ensuring the comprehensiveness and thoroughness of the cleaning; the staggered cleaning rollers 30 can more effectively remove impurities and residues on the surface of the non-woven fabric, reducing subsequent processing problems caused by incomplete cleaning; the cleaned non-woven fabric can reduce the wear of the cutting tools and equipment during the slitting process, helping to extend the service life of the equipment; and the thoroughly cleaned non-woven fabric is less likely to have defects caused by impurities or residues in subsequent processing, thereby improving the overall quality of the product.

[0034] Further, in this embodiment, the axial center distance between two adjacent cleaning rollers 30 is 38 cm to 42 cm; the optimal choice is 40 cm.

[0035] Further, in this embodiment, a dust removal non-woven fabric 110 is provided on the outer surface of the cleaning roller 30; the dust removal non-woven fabric 110 can be adhesively attached to the outer surface of the cleaning roller 30 by double-sided tape; the dust removal non-woven fabric 110 is a filtering material composed of oriented or random fibers and is reinforced by physical, chemical or mechanical methods, and is widely used in various industrial dust removal equipment.

[0036] Further, in this embodiment, the dust removal non-woven fabric 110 is coated with an adhesive solution, and the adhesive solution is one of an epoxy resin adhesive solution, a urethane adhesive solution or a polyvinyl acetate adhesive solution; by coating the adhesive solution on the dust removal non-woven fabric 110, the dust removal non-woven fabric 110 has adhesiveness, can effectively enhance the adsorption capacity for dust or dirt, and can prevent secondary pollution caused by the shedding of dust particles.

[0037] Further, in this embodiment, the upper roll assembly includes an upper cloth air shaft 40, and the upper cloth air shaft 40 is used to guide the non-woven fabric to the cloth guiding assembly;

[0038] The upper cloth air shaft 40 is respectively installed in the upper cloth arm card slots of the frame 10 and locked, and the non-woven fabric on the upper cloth air shaft 40 can be lifted to the specified slitting height by the upper cloth arm cylinder.

[0039] Further, in this embodiment, the cloth guiding assembly further includes an expanding roller 50, and the expanding roller 50 is arranged near the slitting assembly, and the expanding roller 50 is used to adjust the width of the non-woven fabric; by adjusting the width of the non-woven fabric with the expanding roller 50, the width of the non-woven fabric entering the slitting assembly can be changed.

[0040] Further, in this embodiment, the slitting assembly includes a cutting guide roller 60 and a slitting mechanism 70. The cutting guide roller 60 is disposed adjacent to the slitting mechanism 70, and the slitting mechanism 70 is configured to cut the non-woven fabric passing through the cutting guide roller 60. The cutting guide roller 60 is a pneumatic cutting guide roller, and the slitting mechanism 70 includes a pneumatic slitting knife.

[0041] Further, in this embodiment, the winding-down assembly includes a main driving pulley 80, a sub-driving pulley 90, and a winding-down air shaft 100. The winding-down air shaft 100 is disposed between the main driving pulley 80 and the sub-driving pulley 90. The non-woven fabric passes through the main driving pulley 80 and the sub-driving pulley 90 and then reaches the winding-down air shaft 100. After a paper tube of the required size is cut and loaded into the winding-down air shaft 100, it is inflated. The winding-down air shaft 100 is disposed between the main driving pulley 80 and the sub-driving pulley 90 and can be locked by the main driving pulley 80 and the sub-driving pulley 90.

[0042] The working process of a non-woven fabric slitting machine according to this embodiment will be fully described below in combination with the above content.

[0043] First, the non-woven fabric to be slit is accurately inserted into the upper fabric air shaft 40 of the slitting machine to ensure that the fabric remains flat and wrinkle-free during subsequent processing. Subsequently, both ends of the upper fabric air shaft 40 are firmly installed in the upper fabric arm slots of the frame 10 and fastened using a locking device to prevent sliding or deviation during processing. After installation, the cylinder device of the upper fabric arm is started, and the strong power of the cylinder will drive the upper fabric air shaft 40 to slowly rise to the preset slitting height. At the same time, the left and right edges of the non-woven fabric in the horizontal direction are adjusted to ensure that the edges of the non-woven fabric are neat and consistent without skewing. After confirming that everything is correct, the upper fabric air shaft 40 is inflated to expand and closely fit the fabric, providing a stable support for the subsequent cutting process.

[0044] Next, several fabric guiding rollers 20 are provided in the fabric guiding assembly, and two cleaning rollers 30 are provided between the several fabric guiding rollers 20. The two adjacent cleaning rollers 30 are arranged at intervals and offset. This arrangement of the two cleaning rollers 30 can guide the non-woven fabric to pass through an S-shaped winding path. The purpose of this setting is to comprehensively and deeply clean both the front and back sides of the non-woven fabric. As the fabric moves slowly, the particulate matter, fiber debris, and fine dust attached to its surface will be firmly captured by the adhesive layer on the cleaning roller and adhered to the roller surface, thereby effectively reducing the impurity residue on the fabric. More effectively remove the impurities and residues on the surface of the non-woven fabric. And by providing a dust removal non-woven fabric 110 on the outer surface of the cleaning roller 30, the dust removal non-woven fabric 110 is coated with an adhesive solution, and the adhesive solution is one of an epoxy resin adhesive solution, a urethane adhesive solution, or a polyvinyl acetate adhesive solution, so that the dust removal non-woven fabric 110 has adhesiveness, can effectively enhance the adsorption capacity for dust or dirt, and can prevent secondary pollution caused by the shedding of dust particles.

[0045] Then, after the upper cloth air shaft 40 is inflated and the fabric is confirmed to be stable, the fabric will move forward along the preset path. First, it is smoothly guided by the fabric guiding roller, then cleaned by the cleaning roller 30, and finally combed and formed by the fabric guiding roller 20. Subsequently, it enters the expansion roller 50 to adjust the width of the non-woven fabric, that is, to perform a slight stretching and flattening operation on the non-woven fabric to ensure that the fabric is in the best state during cutting. Immediately afterwards, the non-woven fabric passes through the cutting guide roller 60. The cutting guide roller 60 is a pneumatic cutting guide roller. In this link, the non-woven fabric is precisely cut by the slitting mechanism 70 or high-speed air flow. The cut fabric continues to move forward, passes through the main driving wheel 80 and the auxiliary driving wheel 90, and finally reaches the lower winding air shaft 100. At this time, a paper tube meeting the required size needs to be installed on the lower winding air shaft 100 in advance and the lower winding air shaft 100 is inflated to make it expand and ready to receive the cut fabric. Subsequently, the lower winding air shaft 100 is placed between the main driving wheel 80 and the auxiliary driving wheel 90, and the product discharging button is pressed to start the locking mechanism to lock the main driving wheel 80 and the auxiliary driving wheel 90, and then the lower winding air shaft 100 is locked through the main driving wheel 80 and the auxiliary driving wheel 90 to ensure that the cut non-woven fabric can be firmly wound on the paper tube during the winding process.

[0046] Finally, gently pull out a suitable length of non-woven fabric from the lower winding air shaft 100, and use scissors or special tools to cut off the front section of the non-woven fabric that does not meet the required size; at this time, start the pneumatic cutting knife device, and make the cutting knife perform fast and accurate cutting according to the preset size through an accurate control system; after the cutting is completed, wind the cut fabric of the appropriate size onto the lower winding air shaft 100 until the required winding amount is reached; during the winding process, the magnetic powder brake mechanism needs to be turned on in advance, and adjusted to an appropriate tension value according to factors such as the material, thickness, and processing speed of the fabric; this can not only ensure that the fabric remains flat and wrinkle-free during the winding process, but also effectively prevent the fabric from deforming or breaking due to excessive tension; at the same time, turn on the automatic edge sensor adjustment device to achieve real-time monitoring and automatic adjustment of the edge of the non-woven fabric, ensuring the neatness and consistency of the edges of the finished product.
