Description

Technical Field

[0001] This utility model relates to the field of fabric splitting machine technology, specifically a linkage mold for high-speed cutting of misaligned grid patterns in a vertical fabric splitting machine. Background Technology

[0002] The high-speed slitting die for misaligned grid patterns, as a core component of special textile processing equipment, faces significant technical bottlenecks in its traditional process. Current technology uses double-sided moving baffles to mount the pattern die, requiring a cyclical sequence of actions: "slitting → die retraction and reset → lateral displacement → secondary feed" to achieve alternating cutting of the misaligned grid pattern. This operating mode suffers from the following systemic defects:

[0003] (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 actions, which leads to an exponential increase in the programming complexity of the CNC system, significantly increasing the debugging cycle and the risk of misoperation.

[0004] (2) Mechanical efficiency and reliability are limited. Frequent reciprocating retraction and lateral movement of the blade reduces the effective cutting time to less than 40%. Furthermore, under high-speed conditions, precision transmission components such as ball screw pairs are subjected to alternating impact loads, which accelerates guide rail wear and increases transmission backlash. The overall energy efficiency of the equipment decreases by 25%-30% compared to the theoretical value.

[0005] (3) The processing quality defects are uncontrollable. During the retraction-displacement process, the die assembly generates non-orthogonal friction with the velvet fabric, which causes the following quality problems: the fibers on the surface are stretched axially due to shear stress ("fuzzing" effect); the texture deviation of ≥0.2mm appears at the misaligned die joint; and the high-density fabric (≥300g / m²) produces irreversible weft skew deformation.

[0006] The aforementioned technological defects have created three major contradictions prevalent in the industry: a negative correlation between processing accuracy and efficiency, a discrepancy between equipment maintenance costs and production capacity, and technical barriers to the yield of high-end fabrics and process compatibility. Currently, there is an urgent need to optimize the kinematics of the mold structure to achieve a highly efficient and stable staggered grid cutting process. Utility Model Content

[0017] Beneficial effects: This utility model provides a high-speed linkage mold for cutting staggered grid patterns in a vertical fabric cutting machine, which has the following advantages:

[0018] (1) This utility model controls the template driving device on one side to drive the front and rear templates to open and close, thereby driving the front and rear template teeth to move alternately. This allows the pattern template to complete the cutting of the single-sided staggered pattern without retracting the blade or moving laterally. This simplifies the cutting action of the staggered pattern, improves the stability of the machine in the process of cutting the staggered pattern, greatly improves the machine's working efficiency and fabric quality, and reduces the defect rate caused by the "fuzzing" phenomenon.

[0019] (2) This utility model takes into account the force problem of the template driving device. By designing and installing linear bearing components and guide components, it ensures the balance and stability of the mechanism during linkage. It can not only prevent rotation due to torque during the extension and retraction process, which is conducive to maintaining the linearity of the action, but also eliminate the hidden danger of top rod deformation, improve the accuracy of extension and retraction movement, and help improve the service life of precision parts, reduce the frequency of machine maintenance, reduce machine noise, and improve the working environment and work intensity of workshop workers.

[0049] Combination Figure 6 The specific structure of linear bearing assembly 5-6 will be further explained.

[0050] The linear bearing assembly 5-6 includes a linear guide rod 5-63, a fixed support 5-64, a front fixed plate 5-61, and a rear fixed plate 5-62.

[0051] When the front and rear die templates open and close, the linear bearing assembly 5-6 can help maintain the balance of motion, improve the stability of the die drive device 5 during extension and retraction, eliminate the risk of deformation of the telescopic top rod, improve the accuracy of linear motion, extend the service life of precision parts, and reduce machine noise.

[0052] In this embodiment 1, the fabric cutting mold mechanism 1 also includes guide components 5-6, combined with Figure 5 The specific structure of guide components 5-7 will be further explained.

[0053] The guide assembly 5-7 includes a guide post fixing seat 5-71, a guide post 5-72, and a guide post fixing sleeve 5-73. The guide post fixing seat 5-71 is mounted on the base plate 4. The guide post 5-72 is slidably mounted on the guide post fixing seat 5-71, and the guide post 5-72 is arranged parallel to the telescopic drive assembly 5-1 in the telescopic direction. The top end of the guide post 5-72 is fixedly connected to the connecting rod 5-2 through the guide post fixing sleeve 5-73.

[0054] In this embodiment 1, the template driving device 5 may be damaged by lateral displacement due to uneven load, inertia, or external interference during the pushing process. The guide components 5-7 can ensure that the movement trajectory is strictly along the axial direction through rigid constraints, while also balancing the pushing force and maintaining the linearity of the movement at all times.

[0055] The working principle of this utility model is as follows:

[0056] Two sets of fabric splitting mold mechanisms 1 are installed transversely along the base plate 4, and the fabric to be split passes between the two sets of fabric splitting mold mechanisms 1. The template driving devices 5 in the two sets of fabric splitting mold mechanisms perform synchronous telescopic movements, and the front blade template 2-2 of one fabric splitting mold mechanism and the rear blade template 3-2 of the other fabric splitting mold mechanism cooperate to close the mold. When the fabric to be split passes through the two sets of fabric splitting mold mechanisms 1, the template teeth of the two sets of fabric splitting mold mechanisms are alternately distributed in the transverse direction to form a staggered grid pattern (different pile height). After a certain size of staggered grid is formed, the front and rear template teeth of the two sets of fabric splitting mold mechanisms alternately telescopic, corresponding to close the mold, thereby forming a staggered grid (different pile height) in the longitudinal direction as well, thus achieving the desired effect. Figure 7 The fabric shown has a staggered checkered pattern cut.

[0057] In this 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, square structures.

[0058] In this utility model, the specific process of alternating extension and retraction of the front and rear template teeth in the fabric splitting mold mechanism is as follows:

[0059] The template drive devices 5 at both ends of the fabric cutting mold mechanism 1 extend, and the template drive devices 5 drive the connecting rod 5-2 to push it away from the mold closing direction. At this time, the connecting rod 5-2 drives the connecting plate 2-4 and the die telescopic linkage plate assembly 5-5 to move away from the mold closing direction through the linkage plate I 5-3. The linkage plate II 5-4 drives the front die template 2-2 to move linearly away from the mold closing direction along the linear guide rod 5-63 of the linear bearing assembly 5-6. At the same time, one end of the die telescopic linkage plate assembly 5-5 swings in a circular motion away from the mold closing direction around the bearing positioning shaft 5-55 by the linkage plate I 5-3, while the other end of the die telescopic linkage plate assembly 5-5 drives the rear die template 3-2 to move linearly towards the mold closing direction along the linear guide rod 5-63 of the linear bearing assembly 5-6. At this time, the front die template 2-2 and the rear die template 3-2 perform a relative closing motion, that is, the front template teeth 2-1 on the front die template 2-2 retracts and the rear template teeth 3-1 extend. Conversely, when the template drive devices 5 at both ends of the fabric cutting mold mechanism 1 retract, the front template 2-2 and the rear template 3-2 open relative to each other. That is, the front template teeth 2-1 on the front template 2-2 extend, and the rear template teeth 3-1 retract. This cycle repeats, with the template drive device 5 driving the front template 2-2 and the rear template 3-2 to open and close, thereby driving the front template teeth 2-1 and the rear template teeth 3-1 to alternately extend and retract. This allows the pattern cutting template to complete the cutting of a single-sided staggered grid pattern without retraction or lateral movement, which is beneficial for improving machine efficiency and fabric quality.
