DETAILED DESCRIPTION

[0013] Preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to illustrate the technical solutions of the present invention in detail.

[0014] Figure 1A closed view of a multifunctional weaving opening device provided by the present invention, Figure 2 An opening diagram of a multifunctional weaving opening device provided by the present invention, the multifunctional weaving opening device of the present invention comprises: a heald frame device and a heald piece device, wherein the heald frame device is the bearing part of the opening operation and comprises an upper heald frame and a lower heald frame, and the upper and lower heald frames cooperate with the movement of the fabric tissue to form an opening for weaving; the heald piece device is used to support the passage of yarn, monitor the yarn tension, flatten the yarn, and perform spatial conversion according to different stages of the opening operation.

[0015] like Figure 1 , 2 As shown: the present invention specifically includes an upper heald frame 1, a lower heald frame 2, a transverse sliding device 3, a longitudinal sliding device 4, a transverse slide rail 5, a longitudinal slide rail 6, a guide block 7, a groove drum 8, a telescopic frame 9, a heald 10, an upper rotating disk 11, a lower rotating disk 12, a contact sensor 13, a porcelain eye 14, an induction ring 15, a yarn 16, and a yarn groove 17; the upper heald frame 1 makes a two-dimensional movement up and down and left and right along the longitudinal sliding device 4 and the transverse sliding device 3, the lower heald frame 2 makes a one-dimensional movement up and down along the longitudinal sliding device 4, the contact sensor 13 is installed on the heald 10, a telescopic rod is set in the steel frame of the telescopic frame, and the telescopic frame and the upper heald frame 1 are fixedly installed in one It is used to cooperate with the upper heald frame to move stably up, down, left and right; the longitudinal sliding device 4 and the longitudinal slide rail 6 are respectively installed on both sides of the upper heald frame 1, the groove drum 8 is installed under the transverse slide rail 5, and a guide block 7 is arranged between the transverse sliding device 3 and the groove drum 8. One end of the telescopic frame 9 is connected to the transverse sliding device 3, and the other end is connected to the upper heald frame 1. The upper rotating disk 11 and the lower rotating disk 12 are respectively installed on the upper heald frame 1 and the lower heald frame 2. The porcelain eye 14 is opened on the upper rotating disk 11 and the lower rotating disk 12. The yarn groove 17 is arranged on the upper rotating disk 11 and the lower rotating disk 12. The yarn passes through the yarn groove 17, and the porcelain eye 14 is installed with an induction ring 15.

[0016] In the present invention, the upper heald frame 1 performs two-dimensional movement up and down and left and right along the longitudinal sliding device 4 and the transverse sliding device 3 according to the product design requirements, and the lower heald frame 2 performs one-dimensional movement up and down along the longitudinal sliding device 4. During production, when the heald frame is opened, the healds 10 are arranged with the front side facing outward, and the porcelain eyes 14 are facing outward for the yarn 16 to pass through. When the heald frame is closed, the healds 10 on the upper and lower heald frames perform partial cross movement. Before the cross occurs, the contact sensor 13 on the heald 10 senses that the distance between the upper and lower healds reaches the safe distance before the healds 10 cross, and then returns the signal to make a The command for the heald 10 to rotate causes the heald 10 to turn sideways outward, and the spacing between the healds is adjusted for the healds on the upper and lower heald frames to cross and complete the closing movement. After the closing is completed, the upper and lower heald frames begin to move in opposite directions, that is, the upper heald frame 1 moves upward, and the lower heald frame 2 moves downward. After the healds 10 on the heald frames leave the crossing position, the contact sensor 13 will issue a rotation command when sensing a safe distance, so that the front of the heald faces outward. In the process of the heald rotating from the front to the outside to the side and from the side to the outside to the front, the surface of the heald 10 will have a positive effect on the widening of the yarn, such as Figure 3 As described, when the yarn passes through the surface of the porcelain eye 14, the temperature of the surface of the porcelain eye increases due to friction. At the same time, during the rotation of the heald, the side of the heald has an expanding effect on the yarn. Because the heald is made of ceramic material, the appearance surface will not have a negative effect of damaging the carbon yarn. The porcelain eye 14 on the heald is equipped with an induction ring 15. When the yarn passes through, the induction ring 15 will sense the tension of the yarn. According to the theoretical tension value of the yarn input by the computer input end, it is judged whether the tension of the yarn passing through the porcelain eye on the heald during production is within a normal range. If the yarn tension is too large, the yarn will produce a sense of pressure on the induction ring 15. The induction ring 15 will convert the sense of pressure of the yarn to itself into the tension of the yarn and return it to the computer for comparison with the input theoretical tension value of the yarn. If it exceeds the normal range, the computer will issue an alarm instruction, and the production needs to be stopped for detection and adjustment. The fabric produced by the multifunctional weaving opening device of the present invention can ensure the consistency of the tension of the yarn, and can solve the problems of unstable mechanical properties of the fabric and poor subsequent prepreg processing effect. At the same time, the space of one page of heald frames on the original equipment is changed into two pages of heald frames, that is, under the condition of a certain space, the number of heald frames that can be installed in the present invention is twice the number of heald frames of the existing equipment.

[0017] The heald of the present invention is embedded with a sensor line, connecting the sensor and the encoder, and the encoder is responsible for converting the signal returned by the sensor into a coding language and transmitting it to the computer for controlling the rotation angle of the heald at different positions, wherein the induction ring is made of ceramic material, because the ceramic material has the advantages of high melting point, high hardness, high wear resistance, oxidation resistance, etc., and the induction ring is set to an elliptical shape. When the yarn passes through friction, heat is generated, and the surface temperature of the induction ring rises, and the yarn groove 17 becomes a semi-elliptical groove, which is conducive to the flattening and sliding of the carbon yarn. When the heald forms an opening in the heald frame movement, the space between the healds in one page of the heald frame becomes larger, and the healds are rotated 90 degrees in the forward direction, and the front of the heald faces outward. When the heald frame moves to form a closed mouth, the healds in the two pages of the heald frame are staggered, and the space between the healds becomes smaller, and then the reverse rotation is 90 degrees, and the side of the heald faces outward. The lateral sliding and longitudinal sliding devices in the present invention are driven by the computer to rotate the groove drum by controlling the rotation of the motor, so as to achieve the effect of the lateral movement of the upper heald frame, and the distance and direction of the lateral movement of the upper heald frame are achieved by inputting the computer program. If the product is a non-twisted fabric or a non-mesh fabric, you can select the variety when inputting the computer program and select the lateral movement parameter of the upper heald frame as 0, that is, the upper heald frame only has longitudinal movement but no lateral movement, and the simple up and down movement cooperates with the lower heald frame to complete the opening and closing heald frame movement to beat the weft and weave the fabric. If the product is a twisted fabric or a mesh fabric, you can select the distance and direction of the upper heald frame to be lateral when inputting the computer program, so that when the upper and lower heald frames are opening, the left and right positions of the warp yarns and the warp yarns change, so as to achieve the twisting effect between the warp yarns and the weft yarns, and form a mesh fabric with the weft yarns, and the carbon yarn passes through the induction ring in the heald.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
