Description

The invention relates to a heald frame device of a ribbon loom.

With the development of social economy, people's consumption of clothing is increasing day by day, not only in terms of quantity, but also more and more in quality requirements. Therefore, people in the textile industry have also made more changes according to the different preferences of consumers. More development and research to earn profits. Among them, whether the service life of the machine and its performance can increase production and reduce the chance of failure has always been the key to improving production quality. Along with the development of textile industry, ribbon weaving machine arises at the historic moment, though the ribbon weaving machine is through the continuous improvement of relevant personage, research, but still its deficiency that needs improvement. As shown in Figure 4, it is the partial structure of a kind of ribbon loom commonly used nowadays, wherein the ribbon loom needs to be provided with several heald frames 5 to achieve the function of the ribbon loom, and the heald frame 5 is a frame, and the upper end of the frame is An upper beam 55, the lower end of the heald frame 5 is the lower beam 52, and a piece 64 is arranged longitudinally in the middle of the heald frame 5, and the chute 641 runs through its upper and lower ends; it is arranged parallel to one side of the lower beam 52 A linkage eccentric rod 53, protruding guide rails 51 are formed on both sides of the heald frame 5. It can be seen that the heald frame 5 is embedded in the two sides of the loom frame 7 with the guide rails 51; Establish a center fixing frame 61, the upper and lower end faces of the side of the center fixing frame 61 are parallelly attached with a positioning ring piece 62, and a central fixing column 63 is connected to the central through hole of the positioning ring piece 62, and the center fixing column 63 then runs through the support chute 641 of the piece 64, so that the center fixing column 63 is locked to the center fixing frame 61 on the other side of the piece 64; .

The operation of the ribbon loom is based on the arrangement of multiple heald frames 5, and cams with different track grooves are required in the transmission mechanism of the ribbon loom to drive the traction of the heald frames 5, so that the heald pieces 54 that pass through the yarn produce various heald frames. A kind of weaving pattern; structure as shown in Figure 4, wherein each piece of heald frame 5 all has support piece 64 longitudinally stretching to be embedded and fixed, and from the central fixed column 63 that vertically penetrates through the chute 641 of support piece 64, adds heald frame 5 The guide rails 51 on both sides are embedded in the setting of the frame 7, which can generally make the operation of the heald frame 5 suitable for high-speed up and down movement and take into account the balance of the movement of the heald frame 5. However, under long-term operation, it will appear Several missing. Wherein, the chute 641 of the support piece 64 is elliptical, mainly to make the central fixed column 63 running through the chute 641 restrain the heald frame 5 when the heald frame 5 moves up and down to keep the linear trajectory movement, but due to the width of the chute 641 It does not have a good and precise fit with the outer diameter of the central fixed column 63, so that the heald frame 5 still shakes from side to side under high-speed motion, and, in consideration of cost, the supporting pieces 64 are all made of iron or general metal materials Its wear resistance is limited, and it is bound to increase the wear rate of the peripheral edge of the chute 641 after years of operation, and the chute 641 of the supporting piece 64 is continuously pushed back and forth, pressing down on the center fixed column 63. Accelerate the wear of the chute 641, and then make the up and down trajectory of the heald frame 5 inaccurate, reduce the weaving tightness of the yarn, and affect the quality of the finished product.

Furthermore, as far as the heald frame 5 is concerned as a whole, the positions of its upper and lower beams are uniform and appropriate, and as a mechanism for pivoting transmission, a linkage eccentric rod 53 is horizontally added below one side of the lower beam 52, so that the heald frame 5. In the case of fast and staggered movements, it is easy to cause the center of gravity to be biased and unstable, so that the finished product woven by the yarn has poor overall density uniformity, and even the unfavorable phenomenon that the yarn is rolled off. Waste of manpower and working hours, in the sophisticated industrial age, this shortcoming is in urgent need of improvement.

The object of the present invention is to provide a heald frame device of a loom that is more stable in high-speed motion, which is mainly to set a balance bar horizontally at the side of the lower beam of the heald frame relative to the interlocking eccentric rod, so as to Balance the weight of the linked eccentric rod to make the heald frame more stable in high-speed operation; set up a pair of clamping blocks to lock and clamp on the side of the center positioning rod in the center of each heald frame, and use the clamping block to The gaps formed on the side faces face each other closely to the central positioning rod, and a fixed block is locked at the end of the pair of clamping blocks, so that the heald frame can closely surround the central positioning rod, and it can better ensure that the heald frame device maintains up and down Stability in linear motion.

The heald frame device of the ribbon loom of the present invention mainly forms guide rails on both sides of a heald frame. The connection between the support beam and the lower support beam, and the interlocking eccentric rod is parallel and horizontally installed under the lower support beam;
