The present invention has a compact design, a simple structure, is practical and reliable, solves the problem of inconvenient operation of threading and yarn guiding, shortens the time of yarn jointing, and improves the working efficiency of the warping machine.

Description

Technical Field

[0001] The present invention relates to the field of textile machinery, in particular to a yarn breakage detection device for warping equipment. Background Art

[0002] The yarn break detection device is an important device in the warping process. When guiding the yarn, the wire collecting plate type yarn break detection device needs to use a hook needle to pass through the porcelain eyelet of the front yarn guide plate, then lift up the porcelain eyelet of the fallen yarn guide hook, and then pass through the porcelain eyelet of the yarn guide plate to hook and guide the yarn. The number of yarns is as many as one thousand, and the workload is so large. In order to improve the efficiency of threading and facilitate operation, it is necessary to develop an automated yarn guide hook support mechanism to solve this problem. Summary of the invention

[0003] The invention provides a yarn guide hook support mechanism of a yarn collecting plate type yarn break detection device of a warping machine. When yarn is guided, a hook support rod is used to lift up all fallen yarn guide hooks, which is convenient for needle threading and yarn guiding, and improves the efficiency of yarn guiding joints.

[0004] The technical solution for achieving the purpose of the present invention is as follows:

[0005] 1. A yarn guide hook mechanism of a yarn collecting plate type yarn break detection device for a warping machine, characterized in that it is composed of a hook support rod, a swing arm, a set screw, a detent pin, a pull rod, a cylinder and a bracket. The hook support rods of each layer are below the yarn guide hook and are separated into left and right parts. The left end of the left hook support rod passes through and extends out of the left vertical plate, and the right end passes through the middle plate. The right end of the right hook support rod passes through and extends out of the right vertical plate, and the left end passes through the middle plate. The hook support rod is supported by the left vertical plate, the middle plate and the right vertical plate and can rotate. The protruding ends of the left hook support rod and the right hook support rod are respectively equipped with swing arms fixed with set screws. There is a groove in the swing arm, and there is a detent pin in the groove. The pin is connected to the pull rod, and the upper part of the pull rod is connected to the cylinder. The left and right cylinders are fixed on the upper part of the left vertical plate and the right vertical plate respectively by the bracket. When leading the yarn, the cylinder pulls the pull rod upward to move upward, and the pin on the pull rod slides in the swing arm, so that the swing arm rotates along the center of the hook support rod, and at the same time drives the hook support rod to rotate, and lifts up all the yarn guide hooks, so that the long porcelain eye holes of the yarn guide hooks are aligned with the porcelain eye holes of the front yarn guide plate and the porcelain eye holes of the rear yarn guide plate, which is convenient for threading the needle and leading the yarn. During warping, the cylinder pushes the pull rod downward to move, so that the hook support rod swings back to the lower position, and the yarn guide hook is kept in the upper position by the tension of the yarn. When the yarn breaks, the yarn guide hook falls down by its own weight.

[0006] 2. The yarn guide hook mechanism of the warping machine's wire collecting plate type yarn break detection device is characterized in that the hook rod is formed by welding two round rods, with rotating shafts at both ends and a hook body in the middle, or with rotating shafts at both ends and a strip-shaped hook body in the middle. When the hook body of the hook rod rotates upward, the eccentric surface of the hook body will lift up all the fallen yarn guide hooks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] Depend on Figure 1 It can be known that the yarn guide hook mechanism of the yarn collecting plate type yarn break detection device of the warping machine of the present invention is composed of a hook rod 16, a swing arm 6, a set screw 8, a pin 7, a pull rod 11, a cylinder 9 and a bracket 10. The hook rods 16 of each layer are below the yarn guide hook 12 and are separated left and right. The left end of the left hook rod 16 passes through and extends out of the left vertical plate 1, and the right end passes through the neutral plate 2. The right end of the right hook rod 16 passes through and extends out of the right vertical plate 5, and the left end passes through the neutral plate 2. The hook rod 16 is supported by the left vertical plate 1, the neutral plate 2, and the right vertical plate 5 and can rotate. The protruding ends of the left hook rod 16 and the right hook rod 16 are respectively equipped with a swing arm 6 fixed with a set screw 8. There is a groove in the swing arm 6, and there is a pin 7 in the groove. The pin 7 of each layer is connected to the pull rod 1 1, the upper part of the pull rod 11 is connected with the cylinder 9, and the left and right cylinders 9 are respectively fixed on the upper part of the left vertical plate 1 and the right vertical plate 5 by the bracket 10. When the yarn is introduced, the cylinder 9 pulls the pull rod 11 upward to move upward, and the pin 7 on the pull rod 11 slides in the swing arm 6, so that the swing arm 6 rotates along the center of the hook support rod 16, and at the same time drives the hook support rod 16 to rotate, and lifts all the yarn guide hooks 12, so that the long porcelain eye 13 hole of the yarn guide hook 12 is aligned with the porcelain eye 15 hole of the front yarn guide plate 4 and the porcelain eye 15 hole of the rear yarn guide plate 3, which is convenient for needle threading and yarn introduction. When warping, the cylinder 9 pushes the pull rod 11 downward to move, so that the hook support rod 16 swings back to the lower position, and the yarn guide hook 12 is kept in the upper position by the tension of the yarn. When the yarn is broken, the yarn guide hook 12 falls down by its own weight.

[0013] Depend on Figure 2 It can be seen that the hook rod 16 is formed by welding two round rods 17, with rotating shafts at both ends and a hook body 14 in the middle. The round rod 17 can also be bent into an eccentric crankshaft, or with rotating shafts at both ends and a slat-shaped hook body 14 in the middle. When the hook body 14 of the hook rod 16 rotates upward, the eccentric surface of the hook body 14 will lift up all the fallen yarn guide hooks 12.

[0014] The yarn guide hook 12 supporting mechanism of the yarn break detection device of the warping machine collecting plate of the present invention utilizes the cylinder 9 to drive the multi-layer yarn supporting rods to rotate through the pin 7 on the pull rod 11 through the swing arm 6, so as to lift all the yarn guide hooks 12, so that the yarn break detection device can thread the needle and guide the yarn quickly and conveniently, shortens the yarn guiding time, and improves the working efficiency of the warping machine.

[0015] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
