Large-scale mechanical automatic three-dimensional integral square knitting device

Abstract

The invention discloses a large-scale mechanical automatic three-dimensional integral square knitting device, which comprises a frame, a shell, a spindle, a square chassis, a guide rail, a transversedriving mechanism and a longitudinal driving mechanism. A plurality of guide rails are arranged side by side in the square chassis, and the guide rails are uniformly provided with several grooves in the longitudinal direction; several grooves are arranged side by side in the horizontal direction of the guide rail to form a sliding groove for the spindle to slide; the spindles are arranged in a rowto slide in the sliding groove; the spindles are ellipsoidal and the length is greater than the width of the groove; both ends of the guide rail are connected with the longitudinal driving mechanism;the longitudinal driving mechanism drives the guide rail to move in the longitudinal direction of the guide rail; the transverse driving mechanism drives the spindle to move in the sliding groove. According to the large-scale mechanical automatic three-dimensional integral square knitting device, the spindle clamping phenomenon is not easy to occur in the manufacturing process of three-dimensional knitted fabric, the spindle and the guide rail are controlled to move in the weaving space by full automation, the yarn can form the three-dimensional knitted fabric at the knitted surface so as toachieve the mechanization and automation of the three-dimensional knitting machine and achieve the goal of improving the production efficiency of the product.

Description

technical field [0001] The invention relates to the technical field of three-dimensional weaving, in particular to a large-scale mechanical automatic three-dimensional integral square weaving equipment. Background technique [0002] The three-dimensional braiding machine is the core of equipment for preparing composite material preforms. In the three-dimensional weaving method, the most widely used method is the four-step method for three-dimensional weaving. The weaving yarns are arranged in a matrix in rows and columns, and each weaving yarn is individually controlled by a spindle, and the spindles move alternately along the rows and columns to form an overall preform with a certain size and shape. [0003] During the operation of the existing three-dimensional knitting machine, due to the problem of positioning, misalignment often occurs, causing jams; moreover, the noise and vibration are large during the operation; this not only increases the labor intensity and danger...

Problems solved by technology

[0003] During the operation of the existing three-dimensional knitting machine, due to the problem of positioning, misalignment often occurs, causing jams; moreover, the noise and vibration are large during the operation; this not only increases the labor intensity and danger of the workers, but also It is necessary to suspend production to check and repair the machine, which is undoubtedly time-consuming and laborious, and also reduces the efficiency of production; at the same time, the traditional three-dimensional knitting machine is carried out by manual weaving, which requires the coordination of multiple people to weave, and the labor intensity is high. The tightness of the action connection between multi-person manual operation and machine operation will become the main decisive factor that the degree of coordination cannot be effectively improved. The consistency of the quality of the three-dimensional braided fabric cannot be guaranteed, and the production efficiency is very low.

With the progress of society and the development of economy, manual weaving of three-dimensional fabrics can no longer meet the needs of the market, so an automatic three-dimensional fabric weaving machine is urgently needed to solve the problems caused by manual weaving
