Description

Technical Field

[0001] The invention relates to the technical field of fabric cutting machines, in particular to a linkage mould for cutting dislocated lattice patterns at high speed for a vertical fabric cutting machine. Background Art

[0002] As the core component of special textile processing equipment, the high-speed cutting and dislocation pattern linkage mold has significant technical bottlenecks in its traditional process. The current process uses double-sided moving baffles to carry the pattern mold, and needs to execute the cyclic action sequence of "cutting → retracting the mold → lateral displacement → secondary feeding" to achieve alternating cutting of dislocation patterns. This operation mode has the following systematic defects: (1) The motion control is highly complex. The program instructions for multi-axis linkage need to coordinate the baffle displacement, die advance and retreat, and lateral compensation movements, which leads to an exponential increase in the complexity of CNC system programming, significantly increasing the debugging cycle and the risk of misoperation.

[0003] (2) Mechanical efficiency and reliability are limited. Frequent reciprocating and lateral movement of the knife makes the effective cutting time account for less than 40%. In addition, under high-speed conditions, precision transmission components such as ball screw pairs are subjected to alternating impact loads, which accelerates the wear of the guide rails and the expansion of the transmission backlash. The overall energy efficiency of the equipment is reduced by 25%-30% compared with the theoretical value.

[0004] (3) Processing quality defects are uncontrollable. The knife die assembly produces non-orthogonal friction with the velvet fabric during the process of retracting and displacing the knife, causing the following quality problems: the fibers on the fleece surface undergo axial stretching due to shear stress ("hair pulling" effect); a grain deviation of ≥0.2mm occurs at the misaligned joint; and high-density fabrics (≥300g / m²) produce irreversible weft deformation.

[0005] The above-mentioned process defects have caused three common contradictions in the industry: the negative correlation between processing accuracy and efficiency, the inverted phenomenon between equipment maintenance costs and production capacity, and the technical barriers between the yield rate of high-end fabrics and process matching. At present, it is urgent to achieve an efficient and stable staggered grid cutting process by kinematically optimizing the mold structure. Summary of the invention

[0044] The guide assembly 5-7 includes a guide column fixing seat 5-71, a guide column 5-72 and a guide column fixing sleeve 5-73, the guide column fixing seat 5-71 is installed on the base plate 4, the guide column 5-72 is slidably installed on the guide column fixing seat 5-71, and the guide column 5-72 is arranged parallel to the telescopic direction of the telescopic driving assembly 5-1, and the top end of the guide column 5-72 is fixedly connected to the connecting rod 5-2 through the guide column fixing sleeve 5-73.

[0045] In this embodiment 1, the template driving device 5 may be damaged by lateral deviation during the pushing process due to uneven load, inertia or external interference. The guide assembly 5-7 can ensure that the motion trajectory is strictly along the axis direction through rigid constraints, while playing a role in balancing the driving force and always maintaining the linearity of the action.

[0046] The working principle of the present invention is as follows: Two sets of cloth-cutting mold mechanisms 1 are installed along the transverse direction of the bottom plate 4, and the fabric to be cut passes between the two sets of cloth-cutting mold mechanisms 1. The template driving devices 5 in the two sets of cloth-cutting mold mechanisms perform synchronous telescopic movements, and the front knife template 2-2 of one cloth-cutting mold mechanism and the rear knife template 3-2 of the other cloth-cutting mold mechanism cooperate to close the mold. When the fabric to be cut passes through the two sets of cloth-cutting mold mechanisms 1, the template teeth of the two sets of cloth-cutting mold mechanisms are alternately matched and distributed in the transverse direction to form a staggered grid pattern (with different hair heights). After a staggered grid of a certain size is formed, the front and rear template teeth of the two sets of cloth-cutting mold mechanisms are alternately extended and retracted, and the molds are closed accordingly, thereby forming a staggered grid (with different hair heights) in the longitudinal direction, thereby achieving the following Figure 7 The fabric shown is cut in a staggered pattern.

[0047] In the present invention, the shapes of the front template teeth 2-1 and the rear template teeth 3-1 are determined according to the actual staggered grid pattern, and can be, but are not limited to, a square structure.

[0048] In the present invention, the specific process of the alternating extension and retraction of the front and rear template teeth in the cloth cutting mold mechanism is as follows: The template driving device 5 at both ends of the cutting mold mechanism 1 is controlled to make an extending movement, and the template driving device 5 drives the connecting rod 5-2 to be ejected away from the mold closing direction. At this time, the connecting rod 5-2 drives the linkage plate II 5-4 and the knife mold telescopic linkage plate assembly 5-5 to move away from the mold closing direction through the linkage plate I 5-3, and the linkage plate II 5-4 drives the front knife mold plate 2-2 to make a linear motion along the linear guide rod 5-63 of the linear bearing assembly 5-6 away from the mold closing direction. At the same time, one end of the knife mold telescopic linkage plate assembly 5-5 is swung in a circle around the bearing positioning shaft 5-55 away from the mold closing direction by the linkage plate I 5-3, and the other end of the mold telescopic linkage plate assembly 5-5 drives the rear knife mold plate 3-2 to make a linear motion along the linear guide rod 5-63 of the linear bearing assembly 5-6 toward the mold closing direction. At this time, the front knife mold plate 2-2 and the rear knife mold plate 3-2 make a relative closing motion, that is, the front mold plate teeth 2-1 on the front knife mold plate 2-2 make a contraction motion, and the rear mold plate teeth 3-1 make an extension motion. On the contrary, when the template driving devices 5 at both ends of the cloth cutting mold mechanism 1 make a contraction movement, the front knife template 2-2 and the rear knife template 3-2 make a relative opening movement, that is, the front template teeth 2-1 on the front knife template 2-2 make an extension movement, and the rear template teeth 3-1 make a contraction movement. In this way, the template driving device 5 drives the front knife template 2-2 and the rear knife template 3-2 to make an opening and closing movement, thereby driving the front template teeth 2-1 and the rear template teeth 3-1 to make an alternating extension and contraction movement, so that the pattern knife template can complete the cutting work of the single-side dislocation grid pattern without retracting the knife and moving horizontally, which is beneficial to improving the working efficiency of the machine and the quality of the cloth surface.
