[0002] The slitting machine, also known as the slitting machine, separates the double-layer warp knitted fabric into two pieces with a plush surface by cutting with a band knife. The double-layer warp knitted fabric is introduced into the working area of ​​the slitting machine through an induction device. The guide device fixes the fabric on the cutting path to ensure that the fabric maintains tension and flatness throughout the slitting process to improve cutting accuracy. The band knife is usually a thin and sharp circular blade that can move in a high-speed cycle to ensure smooth cutting. The speed and angle of the band knife can be adjusted according to the fabric thickness, tissue pile density and cutting requirements. The warp knitted fabric moves slowly with the stable support of the guide device, and the band knife makes precise cuts along the tissue pile connection area in the middle of the fabric. The band knife splits the pile connecting the two sides of the base fabric from the middle, so that the warp knitted fabric is separated into two independent plush fabrics. The cutting process is fast and accurate, ensuring a neat cut and minimizing fiber loss.

[0025] Accordingly, a working method of a slitting mechanism capable of forming a variety of patterns is disclosed, comprising:

[0026] Conventional slitting method: the warp knitted fabric enters the slitting mechanism through the cloth feed roller, and the tissue pile in the center of the two base fabrics of the warp knitted fabric is cut by the band knife to form two pieces of plush fabric. The plush fabric is respectively sent out by the cloth feed roller and then rolled up; two pattern molds are located on both sides of the warp knitted fabric, respectively against the base fabrics on both sides of the warp knitted fabric, so that the warp knitted fabric cooperates with the grooves and protrusions of the pattern molds, and the cloth feed roller makes the warp knitted fabric tensile, so that the tissue pile moves accordingly. After the band knife cuts, the base fabric of the plush fabric is restored to flatness, and the pile on the surface of the base fabric forms a pattern similar to the pattern mold;

[0027] Switching to different patterns: The warp knitted fabric stops feeding, the mold switching assembly drives the two mold shafts to descend, and then the mold shafts rotate to switch to another pattern mold. After the switching is completed, the two mold shafts rise and reset, and the warp knitted fabric resumes feeding;

[0028] Adjustment method when warp knitted fabric thickness changes: After the warp knitted fabric is replaced, the spacing adjustment motor of the spacing adjustment assembly drives the two moving stands to move closer or farther away, so that the spacing between the two pattern molds is adjusted to be consistent with the thickness of the new warp knitted fabric;

[0029] The staggered pattern is formed as follows: after the warp knitted fabric is fed for a specified length, the warp knitted fabric stops feeding, and the baffle longitudinal movement motor of the baffle longitudinal movement assembly drives the baffle longitudinal movement base to move, driving the baffle transverse movement fixed seat, the baffle bracket, and the baffle to approach the belt knife. After the baffle abuts against the warp knitted fabric, the mold transverse movement motor of the mold transverse movement assembly drives the second seat plate of the mold to move, driving the mold shaft and the pattern mold to move transversely for a certain distance, and the baffle longitudinal movement motor drives the baffle to retract, the pattern mold abuts against the warp knitted fabric, and the warp knitted fabric resumes feeding and feeds the specified length; the warp knitted fabric stops feeding, and the baffle longitudinal movement motor drives the baffle to extend and abut against the warp knitted fabric, and the mold transverse movement assembly drives the pattern mold to retreat the previous transverse movement distance, and the pattern mold returns to its original position, and the baffle longitudinal movement motor drives the baffle to retract, the pattern mold abuts against the warp knitted fabric, and the warp knitted fabric resumes feeding; repeat the above actions to form a staggered pattern;

[0030] Production method of plush cloth of different specifications: the warp knitted cloth stops feeding, the overall adjustment motor of the overall adjustment component drives the moving platform to move synchronously and in the same direction, and the warp knitted cloth moves accordingly due to the action of the pattern mold. At this time, the position of the belt knife remains unchanged, and the fluff remaining on one side of the base cloth after the tissue pile is cut by the belt knife becomes longer as a whole, and the fluff on the other side of the base cloth becomes shorter as a whole, so as to produce plush cloth of different specifications.

[0034] 3. The pattern mold of the present invention can be moved laterally, and can form a staggered pattern by cooperating with the start and stop of the feeding of the warp knitted fabric; the present invention is provided with a baffle, which can be moved longitudinally before the pattern mold is moved laterally, abutting the warp knitted fabric, and avoiding disturbance of the warp knitted fabric when the pattern mold moves;

[0035] 4. The present invention can switch multiple pattern molds through the mold rotating shaft, and the baffle can be provided with grooves and protrusions. The baffle can also be used as a spare pattern mold to form more types of patterns;

[0036] 5. The structure of the present invention is stable, reliable and easy to operate. The control components are arranged at both ends of the flower mold instead of in the middle of the flower mold, which is convenient for installation, maintenance and repair. The maintenance and installation personnel do not need to enter the middle of the whole machine, but only need to disassemble and repair at both ends of the equipment.

[0072] Conventional slitting method: the warp knitted cloth enters the slitting mechanism through the cloth feed roller, and the tissue pile in the center of the two base fabrics of the warp knitted cloth is cut by the band knife to form two pieces of plush cloth. The plush cloth is respectively sent out by the cloth feed roller and then rolled up; two pattern molds 001 are located on both sides of the warp knitted cloth, respectively against the base fabrics on both sides of the warp knitted cloth, so that the warp knitted cloth cooperates with the grooves and protrusions of the pattern mold 001, and the cloth feed roller makes the warp knitted cloth have tension, so that the tissue pile moves accordingly. After the band knife cutting, the base fabric of the plush cloth is restored to flatness, and the pile on the surface of the base fabric forms a pattern similar to that of the pattern mold 001.

[0073] Switching to different patterns: the warp knitted fabric stops feeding, the mold switching assembly 200 drives the two mold shafts 006 to descend, and then the mold shafts 006 rotate and switch to another pattern mold 001. After the switching is completed, the two mold shafts 006 rise and reset, and the warp knitted fabric resumes feeding.

[0074] Adjustment method when the thickness of the warp knitted cloth changes: After the warp knitted cloth is replaced, the spacing adjustment motor 501 of the spacing adjustment assembly 500 drives the two moving stands 004 to move closer or farther away, so that the spacing between the two pattern molds 001 is adjusted to be consistent with the thickness of the new warp knitted cloth.

[0075] Staggered pattern formation method: After the warp knitted fabric is fed for a specified length, the warp knitted fabric stops feeding, and the baffle longitudinal movement motor 401 of the baffle longitudinal movement assembly 400 drives the baffle longitudinal movement base 403 to move, driving the baffle transverse movement fixed seat 303, the baffle bracket 005, and the baffle 002 to approach the belt knife. After the baffle 002 abuts against the warp knitted fabric, the mold transverse movement motor 101 of the mold transverse movement assembly 100 drives the mold second seat plate 103 to move, driving the mold shaft 006 and the pattern mold 001 to move horizontally for a distance, and the baffle longitudinal movement motor 401 drives the baffle 002 to retract, the pattern mold 001 abuts against the warp knitted cloth, and the warp knitted cloth resumes feeding and feeds a specified length; the warp knitted cloth stops feeding, and the baffle longitudinal movement motor 401 drives the baffle 002 to extend and abut against the warp knitted cloth, and the mold transverse movement assembly 100 drives the pattern mold 001 to retreat the previous transverse movement distance, and the pattern mold 001 returns to its original position, and the baffle longitudinal movement motor 401 drives the baffle 002 to retract, and the pattern mold 001 abuts against the warp knitted cloth, and the warp knitted cloth resumes feeding; repeat the above actions to form a staggered pattern. Alternatively, the following method is adopted: the baffle 002 is replaced with a pattern structure identical to that of the pattern mold 001, the pattern of the baffle 002 is staggered with the pattern mold 001 along the length of the pattern mold 001, and the baffle 002 and the pattern mold 001, driven by the baffle longitudinal movement component 400 and the spacing adjustment component 500, move forward or backward in turn to abut against or move away from the warp knitted cloth, and the warp knitted cloth stops feeding during the rotation.

[0076] Production method of plush cloth of different specifications: the warp knitted cloth stops feeding, the overall adjustment motor 601 of the overall adjustment component 600 drives the moving stand 004 to move synchronously and in the same direction, and the warp knitted cloth moves accordingly under the action of the pattern mold 001. At this time, the position of the belt knife remains unchanged, and the fluff remaining on one side of the base cloth after the tissue pile is cut by the belt knife becomes longer as a whole, and the fluff on the other side of the base cloth becomes shorter as a whole, so as to produce plush cloth of different specifications.

[0077] Working principle of the present invention:

[0078] In the process of cutting the tissue pile of the warp knitted cloth with a knife to form two pieces of plush cloth, the warp knitted cloth is squeezed by a mold with grooves and protrusions. When the knife is cutting, although the knife cuts in the form of a straight line, the shape of the base fabric of the warp knitted cloth changes, so that the length of the pile remaining on the base fabric changes, and plush cloths with different pile heights are formed after cutting, so that the surface of the plush cloth has flower patterns with different patterns.

[0079] The groove and protrusion design of the mold can control the height and distribution of the fluff. Different mold shapes and spacing can achieve different fluff height effects, making the surface of the plush cloth present a rich three-dimensional and layered sense. For example, rectangular protrusions and grooves can form stripes and checkered patterns on the surface of the plush cloth; arc-shaped protrusions and grooves can form waves, polka dots, hemispheres and other patterns on the surface of the plush cloth; conical protrusions and grooves can form lawns, spikes and other patterns on the surface of the plush cloth. Since the length of the tissue pile is constant, the shapes of the molds on both sides of the knife need to fit each other, that is, if one mold is convex, the mold on the other side should be concave to evenly distribute the hair height. On the cross section perpendicular to the knife, the spacing between the two molds should be equal to the maximum length of the tissue pile under natural stretch.

[0080] Since the thickness of warp knitted fabrics is not uniform, that is, the length of the tissue pile is not uniform, plush fabrics of different thicknesses have different pile structures and elasticity. Adjusting the mold spacing can ensure that the mold spacing and the length of the warp knitted fabric tissue pile remain the same, thereby achieving a better molding effect and a smoother and more consistent surface of the formed plush fabric. The spacing adjustment component 500 of the present invention drives the lead screw to rotate through the spacing adjustment motor 501, and the two spacing adjustment nut seats 505 with reverse teeth drive the two moving platforms 004 to move in the opposite direction, thereby moving closer or farther away, and adjusting the mold spacing.

[0081] Ordinary cloth-cutting machines can only form plush cloth with the same average hair height on both sides. The present invention uses the overall adjustment component 600 and the overall adjustment motor 601 to drive the moving platform 004 to move in the same direction, thereby forming a "favor one side and thin the other side" effect, so that more tissue hair is distributed on one side of the plush cloth, and correspondingly, the hair height of the other side of the plush cloth becomes smaller overall. Therefore, the effect of overall hair height change on the surface of the plush cloth can be formed, and two pieces of plush cloth with different hair specifications can also be formed.

[0082] The present invention can also form a pattern of staggered patterns by moving the pattern mold 001 horizontally. However, when the pattern mold 001 moves, since the two pieces of plush cloth maintain tension through the pattern mold 001, the protrusions on the pattern mold 001 will hook the base fabric of the plush cloth, causing the plush cloth to wrinkle and stack, thereby interfering with the plush cloth. If the pattern mold 001 retreats, the plush cloth will retreat along with it, and the tissue pile will be torn off. The present invention is provided with a baffle 002. When the pattern mold 001 moves, the baffle 002 moves longitudinally in the direction close to the band knife, abuts against the warp knitted cloth, and replaces the pattern mold 001 to keep the two base fabrics of the warp knitted cloth at a suitable distance, so that the tissue pile will not be broken, and the warp knitted cloth will not be pulled horizontally.

[0083] At the same time, the baffle 002 can be flush with the warp knitted fabric on one side, or can be provided with grooves and protrusions to play the role of a mold. Therefore, the baffle 002 is provided with a baffle transverse shifting assembly 300, which can also form a staggered pattern.

[0084] The molds of the present invention can be switched, and by switching the molds, a combination of patterns of different shapes on the plush cloth can be achieved to form a more complex and beautiful style.
