Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and particularly relates to a pattern processing die switching mechanism for a slitting machine. Background Art

[0002] A slitting machine, also known as a cloth slitting machine, is primarily used to slit double-layer velvet fabrics into two pieces of velvet. This equipment is specifically designed for warp-knitted fabrics with a double-layer structure. The two base fabrics are connected by a velvet pile. A band knife cuts the fabric down the middle, creating two pieces of velvet-lined fabric. As the warp-knitted fabric passes through the slitting machine, a guide device secures it in the cutting path. The slitting machine uses a band knife to precisely slit the fabric down the middle, creating two pieces of velvet, while maintaining clean edges and fabric integrity.

[0003] The cut fabric creates a three-dimensional pattern on the cross section. Traditional plush fabrics have a fixed pile height and a relatively simple pattern. The new slitting machine uses different dies to apply pressure to the warp knitted fabric during slitting, controlling the pile height on the surface of the plush fabric. By moving the dies, a staggered pattern is formed.

[0004] The Chinese invention patent with publication number CN117535916A discloses a multi-pattern cloth-cutting mechanism, a cloth-cutting machine and a cloth-cutting method thereof, which are equipped with two cloth-cutting molds. By alternating the cloth-cutting and / or adjusting the opening spacing of the two cloth-cutting molds, textiles with various types of interlaced patterns such as bubbles, squares, and stripes can be achieved, thereby improving the surface quality and three-dimensional sense of the textiles and further increasing the added value of the textiles.

[0005] The first cloth-cutting mold in the above-mentioned invention patent is fixed, and the second cloth-cutting mold is located above the first cloth-cutting mold and can extend and retract toward the warp knitted fabric. Since the two pieces of plush fabric formed after the band knife cutting form a V-shape during transportation, and since the position of the guide roller remains unchanged, when the second cloth-cutting mold alternates with the first cloth-cutting mold, the height of the cloth-cutting mold against the warp knitted fabric also changes accordingly, making it impossible for the cloth-cutting mold to maintain a constant relative position with the band knife cutting point, that is, the V-shaped tip, which will affect the consistency of the pattern formation.

[0006] Furthermore, there are only two types of slitting molds, each with either rectangular or arc-shaped protrusions and grooves. This limits the variety of patterns that can be expanded, such as diamonds or other irregular shapes, and also restricts the curvature of the arcs and the width of the rectangles. Due to the spatial limitations of the slitting machine and the aforementioned issues of varying the abutment position, simply adding a third or fourth slitting mold in the height direction is not an option.

[0007] Therefore, it is urgent to design a new pattern processing mold switching structure to avoid changing the abutment position between the mold and the warp knitted fabric, and to add more mold types to form more patterns and their combinations. Utility model content

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0038] As shown in Figure 1 , 2 , 3, 4, two splitting machine pattern processing die switching mechanisms are symmetrically installed on the splitting machine, and the pattern dies 3 are concave-convexly embedded. A splitting machine pattern processing die switching mechanism comprises a rotating rod 1, a rotating motor 6, a base 7 and a lifting assembly. The base 7 is connected with a transverse and longitudinal moving mechanism. The length direction of the rotating rod 1 is set as the transverse direction, and when moving transversely, the pattern swings in the width direction of the warp-knitted fabric, for example, forming a wavy stripe; the direction perpendicular to the direction of the cutter is set as the longitudinal direction, and when the two splitting machine pattern processing die switching mechanisms move longitudinally in the same direction, the pile height of the two pieces of pile fabric is changed.

[0039] As shown in Figure 3 , 8As shown in Figures 9 and 9, a plurality of pattern molds 3 arranged uniformly or non-uniformly in the annular direction are installed on the rotating rod 1. The rotating motor 6 is connected to the rotating rod 1 and drives the rotating rod 1 to rotate at a specific angle, thereby switching the pattern mold 3 that is in contact with the warp knitted fabric. The rotating motor 6 is connected to the rotating rod 1 through a coupling 8, and the coupling 8 is connected to the through hole of the base 7 through a bearing. The provision of bearings can avoid wear of the coupling caused by long-term rotation. Each slitting machine pattern processing mold switching mechanism is provided with two synchronously running rotating motors 6, which are servo motors or stepper motors or ordinary motors with encoders and sensors. The cross-section of the rotating rod 1 is polygonal or circular.

[0040] Preferably, if Figure 9 、 10 As shown, the rotating rod 1 has a triangular cross-section, and each rod 1 is mounted with three pattern dies 3. The area where the pattern dies 3 are mounted on the rotating rod 1 is flat, and a retaining block is provided to abut against the rear of the pattern dies 3. This prevents the pattern dies 3 from moving when abutting the warp knitted fabric, maintaining a stable pile height. The pattern dies 3 are removably mounted to the rotating rod 1 via multiple bolts, providing a secure and easy-to-install installation and disassembly solution.

[0041] like Figure 3 、 4 As shown in FIG9 , there are two bases 7, which are installed at both ends of the rotating rod 1. The rotating rod 1 can rotate relative to the base 7. A lifting assembly is provided at the bottom of the base 7. The lifting assembly drives the base 7, the rotating rod 1, and the rotating motor 6 to rise and fall, thereby moving away from the pressure plate 2 on the upper part of the flower mold 3 or resetting.

[0042] like Figure 4 、 5 As shown in Figures 6 and 7, the lifting assembly includes one of the following: a cylinder, a gear and rack, a synchronous belt, and a lead screw 4. The lead screw 4 is preferably used. The lifting assembly includes two sets of lifting motors 5, a lead screw 4, a coupling 8, and a nut holder. The output shaft of the lifting motor 5 is connected to the lead screw 4 via the coupling 8. The lead screw 4 is movably connected to the nut holder, which is mounted on the two bases 7 of the switching mechanism. The two lifting motors 5 simultaneously drive the lead screw 4 to rotate, causing the bases 7 at both ends of the rotating rod 1 to rise and fall synchronously.

[0043] The working principle of this utility model:

[0044] The utility model discloses a plurality of different shapes of cloth cutting dies are installed on the rotating rod 1 of the cloth cutting machine, such as different width or curvature, slope, rectangle, arc, cone, rhombus or other geometric patterns, can form staggered blocks, waves, stripes, triangles and other patterns. Compared with the design of single die, the integrated multiple dies on the same rotating rod 1 reduces the downtime and maintenance requirements of the equipment, without the need for shutdown for disassembly, replacement of pattern dies 3 and debugging, greatly improving production efficiency and reducing production cost. These pattern dies 3 can be quickly switched by rotating the rotating rod 1 to adapt to different pattern requirements. The multi-die design makes the pattern of the plush cloth more diversified, allowing quick replacement of patterns according to market demand, increasing the visual appeal and competitiveness of the product. It is convenient to realize personalized custom production, meet the needs of different customers for patterns and improve the added value of the product.

[0045] The rotating rod 1 is controlled by a servo motor or a stepper motor. When it is necessary to switch patterns, the rotating rod 1 is rotated to the corresponding die position, and cloth cutting of different shapes can be performed, realizing the diversification of patterns.

[0046] The pattern die 3 can move longitudinally and transversely on the horizontal plane with the cloth pattern processing die switching mechanism. The direction of the rotating rod 1 is transverse, and the direction perpendicular to the cutter is longitudinal. The height and position of the pattern can be controlled. When it is necessary to change the style of the pattern, such as changing waves to blocks or adjusting the curvature of the waves, the switching action is performed. Since the rotating rod 1 die rotates and interferes with the pressing plate 2 close to the top of the pattern die 3, the utility model solves the problem in the following way: before the rotating rod 1 rotates, the lifting motor 5 lowers the base 7 and the rotating rod 1 through the lead screw 4, avoiding the pressing plate 2 at the top of the pattern die 3; after the rotating rod 1 rotates to switch the pattern die 3, the base 7 and the rotating rod 1 are reset by the lifting motor 5. At this time, the pattern die 3 is parallel to the pressing plate 2 and the height of the tricot cloth remains unchanged.

[0047] Compared with the traditional telescopic pattern die 3, the utility model can maintain consistent pattern visual effects because the replaced pattern die 3 and the original die are at the same height and position. At the same time, the structure of the rotating rod 1 can install a variety of pattern dies 3, realizing the processing of more styles of patterns.

[0048] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of the utility model should be covered within the protection scope of the utility model.
