Abstract
Description
Technical Field
[0001] The utility model belongs to the field of textile equipment, and in particular relates to a pay-off guide device that can be used for yarn coils. Background Art
[0002] Yarn reels are take-up / pay-off drums with yarn wound around them. During textile production, the raw yarn used for weaving or blending will swing violently when it is paid out from the pay-off drum at high speed. If not restricted, the swing amplitude will be too large and it will become entangled with other surrounding transmitted yarns, brackets or equipment parts. Utility Model Content
[0003] In response to the problems in the background technology, the utility model provides a pay-off guide device that can be used for yarn winding materials. The device has a tension adjustment function and, more importantly, can effectively limit the swinging of the yarn during high-speed pay-off.
[0004] Disclosed is a pay-off guide device that can be used for yarn winding materials, comprising a bracket, a fixing rod, a first guide member, a second guide member, a guide wheel, a linear bearing, an adjusting nut block, a spring, and a locking nut;
[0005] The fixing rod is integrally composed of a first screw portion, a polished rod portion and a second screw portion. The middle portion of the fixing rod is the polished rod portion, and the two ends of the fixing rod are the first screw portion and the second screw portion respectively. The end of the first screw portion of the fixing rod is fixedly connected to the bracket.
[0006] The guide wheel is mounted on the polished rod portion of the fixed rod through a linear bearing, and the guide wheel can slide on the middle polished rod of the fixed rod when subjected to external force;
[0007] An adjusting nut block is screwed onto the first screw portion and the second screw portion of the fixing rod, respectively. A spring is provided between the two adjusting nut blocks and the guide wheel, one end of the spring is fixedly connected to the corresponding side surface of the guide wheel, and the other end of the spring is fixedly connected to the corresponding adjusting nut block.
[0008] The first guide member is integrally formed by an adjustment plate and a guide plate, the adjustment plate and the guide plate are arranged perpendicular to each other, the end of the adjustment plate is hinged to the first screw portion of the fixing rod and is locked by a locking nut, and a guide hole is opened on the guide plate;
[0009] The second guide member is arranged behind the guide wheel, the second guide member is fixedly connected to the bracket, and a guide notch is provided on the second guide member.
[0010] The working principle of the above-mentioned pay-off guide device is as follows:
[0011] The yarn coil is placed under the first guide member. When the raw yarn is paid off from the pay-off drum at high speed, it first passes through the guide hole on the guide plate, then passes around the guide notch of the second guide member from below, and finally passes around the guide wheel from below.
[0012] When the locking nut is loosened, the first guide member can swing a certain angle around the first screw portion of the fixing rod through the adjusting plate, and then the locking nut is tightened to fix the first guide member, thereby adjusting the tension of the yarn;
[0013] The first guide member, the second guide member and the guide wheel of the present pay-off guide device can all limit the swinging of the yarn during high-speed pay-off, especially the guide wheel. After being subjected to the external force of the yarn swinging, the guide wheel can slide on the middle light rod of the fixed rod, and reduce the shaking by buffering through the springs on both sides. This buffering-type swing-reducing mechanism can avoid the yarn breakage caused by excessive swinging force at a certain moment and being subject to greater restriction by conventional guide devices; and this device can also adjust the compression degree of the springs on both sides by rotating the adjusting nut block, so that the guide wheel can adapt to different pay-off speeds, that is, adapt to yarns with different swinging amplitudes.
[0014] Preferably, the bracket is integrally formed by a first support plate, a second support plate, and a mounting plate, wherein the first support plate and the second support plate are arranged in parallel and are integrally connected through the mounting plate;
[0015] The end of the first screw portion of the fixing rod is fixedly connected to the first support plate, and the second guide member is fixedly connected to the second support plate through a bolt rod. A plurality of mounting holes are provided on the mounting plate. With such a bracket, the entire device can be installed to a designated position by fastening bolts or screws through the mounting holes of the mounting plate.
[0016] Preferably, an annular groove is provided on the wheel surface of the guide wheel, and the yarn passing around the guide wheel is located in the annular groove, which can prevent the yarn from slipping off the guide wheel.
[0017] Preferably, a stopper is integrally provided above the guide notch of the second guide member to prevent the yarn in the guide notch from slipping off the second guide member.
[0018] Preferably, a rubber ring is fixedly installed in the guide hole of the first guide member to prevent the yarn from being worn when passing through the guide hole.
[0019] Through the above technical solution, the utility model has at least the following beneficial effects:
[0020] The pay-off guide device for yarn winding described in the present application has a tension adjustment function through the design of the locking nut and the first guide member.
[0021] The present invention can effectively limit the swinging of the yarn during high-speed pay-off through the design of the first guide member, the second guide member and the guide wheel; in particular, the guide wheel can slide on the middle rod of the fixed rod after being subjected to the external force of the yarn swinging, and reduce the shaking by buffering through the springs on both sides. Compared with conventional guide devices, it can avoid the yarn breaking caused by excessive swinging force at a certain moment and being subject to greater restriction; and the present invention can also adjust the compression degree of the springs on both sides by rotating the adjusting nut block, so that the guide wheel can adapt to different pay-off speeds, that is, adapt to yarns with different swinging amplitudes.
