Description

Technical Field

[0001] The utility model relates to a yarn storage device for a water jet loom, belonging to the technical field of loom equipment. Background Art

[0002] A "yarn accumulator" is a device that temporarily stores the weft yarn unwound from the bobbin before it is introduced into the shed. It is used on rapier and projectile looms. It typically consists of a motor, a storage drum, a winding disc, a storage quantity detector, a damping ring, a tensioner, and a yarn arrangement mechanism. Yarn breakage is common due to malfunctioning weft accumulators on water jet looms. If the water jet loom is not stopped immediately after a yarn break, the remaining yarn will produce defective products, resulting in considerable economic losses.

[0003] However, in the process of the existing yarn being wound in the yarn storage device, once the yarn breaks, an alarm cannot be issued to remind the surrounding personnel. Now, a water jet loom yarn storage device is urgently needed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a yarn storage device for a water jet loom to solve the problems raised in the above-mentioned background technology. The utility model designs a roller-mounted alarm structure, which can use the spring elasticity to click the alarm switch when the yarn breaks, thereby reminding the surrounding people.

[0005] The lifting of the lifting of the lifting of the lifting of the lifting of the lifting gear is increased, and the lifting of the lifting gear is increased in the amount of lifting power provided on the lifting gear. The lifting of the lifting gear is increased, and the amount of lifting power is increased. The lifting gear is increased in the amount of lifting power provided on the lifting gear.

[0006] Furthermore, casters with foot brakes are installed around the lower end of the movable seat.

[0007] Furthermore, the first limiting wheel and the second limiting wheel are slidably attached to each other.

[0008] Furthermore, the lower end of the movable plate is fixed to a return spring, and the return spring is in an extended state.

[0009] Furthermore, the smooth limiting plate slides inside the upper end of the third limiting wheel.

[0010] Furthermore, the alarm switch is located on the upper side of the third limiting wheel, and the alarm switch is connected to the alarm through a wire.

[0011] The beneficial effects of the utility model: the utility model is a yarn storage device for a water jet loom. Since the utility model adds a welding block, a fixed frame, a first limiting wheel, a second limiting wheel, a reset spring, a movable plate, a third limiting wheel, a smooth limiting plate, an alarm switch and an alarm, our design improvements and actual use have shown that the structure of the device is reasonable. A roller-mounted alarm structure is designed, which can use the spring elasticity to click the alarm switch when the yarn breaks, thereby reminding people around. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a yarn storage device for a water jet loom, comprising a movable seat 1, a fixed frame 7, a movable plate 12 and an alarm switch 15, a yarn storage device support rod 3 is longitudinally mounted on the upper end of the movable seat 1 through a bolt, a yarn storage device support rod 3 is horizontally fixed to the upper end of the yarn storage device support rod 3, a yarn storage device support seat 4 is mounted on the upper end of the yarn storage device support seat 4, a yarn storage device body 5 is fixed to the front end of the yarn storage device body 5 with a welding block 6, a fixed frame 7 is welded to the front end of the welding block 6, a first limiting wheel 8 and a second limiting wheel 9 are fixed to the lower side of the front end of the fixed frame 7, and a fixing frame 7 is fixed to the front end of the fixing frame 7. A return spring 10 is longitudinally installed at the lower end of the interior, strip grooves 11 are opened on the left and right sides of the fixed frame 7, the movable plate 12 slides between the two strip grooves 11, and a third limiting wheel 13 is installed on the upper end of the movable plate 12. A smooth limiting plate 14 is longitudinally fixed to the upper end of the interior of the fixed frame 7, an alarm switch 15 is longitudinally installed on the right side of the upper end of the interior of the fixed frame 7, and an alarm 16 is installed on the right side of the fixed frame 7. This design solves the problem that the existing yarn cannot be alarmed to remind the surrounding people once it breaks during the yarn storage process.

[0019] As a first embodiment of the present invention, casters 2 with brakes are installed around the lower end of the movable base 1. The added casters 2 with brakes facilitate the movement of the movable base 1. The first limiting wheel 8 and the second limiting wheel 9 slide against each other, and the added first limiting wheel 8 and the second limiting wheel 9 can limit the passing yarn.

[0020] The lower end of the movable plate 12 is fixed to the return spring 10, which is in an extended state. The added return spring 10 provides movable support for the movable plate 12 and the third limiting wheel 13. A smooth limiting plate 14 slides inside the upper end of the third limiting wheel 13. The added smooth limiting plate 14 and the third limiting wheel 13 limit the yarn passing through. An alarm switch 15 is located above the third limiting wheel 13 and is connected to an alarm 16 via a wire. When the added third limiting wheel 13 moves upward, it touches the alarm switch 15, causing the alarm switch 15 to control the alarm 16 to sound an alarm.

[0021] As a second embodiment of the present invention: in actual use, the yarn is passed between the first limiting wheel 8 and the second limiting wheel 9, and then passed between the smooth limiting plate 14 and the third limiting wheel 13, and then the yarn is wound around the yarn storage portion of the yarn storage body 5, and then the yarn storage body 5 is controlled to work and the yarn is wound counterclockwise. In this process, because the position of the third limiting wheel 13 is higher than the first limiting wheel 8, the second limiting wheel 9 and the yarn storage portion of the yarn storage body 5, when the yarn storage body 5 is winding the yarn counterclockwise, the yarn storage body 5 is wound around the yarn storage portion. , it will slightly press down the third limiting wheel 13, so that the third limiting wheel 13 slightly presses down the reset spring 10 through the movable plate 12 (at this time, the reset spring 10 is in a slightly compressed state). When the yarn breaks, the reset spring 10 rebounds upward, and the rebound force is transmitted to the third limiting wheel 13 through the movable plate 12, so that the third limiting wheel 13 will move upward instantly and contact the smooth limiting plate 14 and the alarm switch 15, and the alarm switch 15 will control the alarm 16 to sound an alarm to remind people around.

[0022] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
