Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a weft storage device for water jet looms. Background Art

[0002] The weft storage device of a water jet loom refers to a temporary storage device for the weft yarn unwound from the bobbin before it is introduced into the shed. It is used in rapier and projectile looms and is usually composed of an electric motor, a yarn storage drum, a yarn winding disk, a yarn storage amount detector, a damping ring, a tensioner, a yarn arrangement mechanism, etc.

[0003] After searching, a new type of weft storage device for a water jet loom is mentioned in the published application number CN202120526252.3, including a weft storage device for a water jet loom and a yarn winding hub. A wire break self-power-off alarm device is provided on one side of the weft storage device for the water jet loom, a wire jam prevention device is provided on the front of the yarn winding hub, a buckle anti-misalignment device is provided on one side of the yarn winding hub, and a first limit plate is provided on one side of the weft storage device for the water jet loom. The utility model is provided with a first metal conductor, a first spring, a fixing plate, a first insulating plate, a tuning fork, a second insulating plate and a second metal conductor, so that when a water jet loom fails and the yarn breaks, the water jet loom circuit is disconnected in time, and the water jet loom stops working, thereby preventing the water jet loom from continuing to work and producing defective products to cause economic losses. At the same time, the tuning fork makes a loud noise to remind the staff to deal with the water jet loom that stops automatically due to a fault in time, thereby reducing the economic losses caused by yarn breakage.

[0004] Although the above scheme solves the problems mentioned in the background technology, the following shortcomings still exist: when the weft storage device is working, the internal drive motor and other components of the weft storage device will generate noise when working, and this noise will cause discomfort to the staff during use. However, the weft storage device of the water jet loom lacks a structure to reduce the noise, and there is no protective structure above the weft storage device, so it will be hit by objects falling from above and cause damage, affecting the normal use of the weft storage device.

[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] A weft accumulator for a water jet loom comprises a weft accumulator body 1, a support base 11 is arranged at the bottom of the weft accumulator body 1, a first connecting plate 2 and a second connecting plate 3 are respectively connected to the middle position of the top of the support base 11, a driving motor 4 is connected between the first connecting plate 2 and the second connecting plate 3, a winding body 5 is connected to the side of the second connecting plate 3 away from the driving motor 4, a connecting disk 6 is connected to the side of the winding body 5 away from the second connecting plate 3, a driving shaft 7 is connected through the output end of the driving motor 4, the second connecting plate 3, the winding body 5 and the connecting disk 6, and a protective cover 8 is sleeved and connected to the outer side of the weft accumulator body 1.

[0026] In this embodiment, please refer to Figure 1 and Figure 2 The output end of the driving motor 4 is connected to one side of the driving shaft 7 and the connection method is a key connection. The side of the driving shaft 7 away from the driving motor 4 passes through and is connected to the inside of the winding body 5 and is rotatably connected to the center position of the connecting disk 6. One side of the protective cover 8 is connected to a fixing seat 81 and the connection method is welding. The protective cover 8 is installed on the supporting base 11 through the fixing seat 81 using mounting bolts 82 and the installation method is threaded installation. The protective cover 8 is made of high-strength stainless steel and has a semicircular arc structure as a whole. The protective cover 8 is integrally sleeved on the periphery of the weft storage device body 1. The fixing seat 81 is installed on the supporting base 11 by mounting bolts 82, so that the protective cover 8 is sleeved on the upper outer end of the weft storage device to protect the weft storage device body 1.

[0027] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 A plurality of sound-absorbing balls 83 are arranged around one side of the protective cover 8 close to the main body 1 of the weft feeder. The sound-absorbing balls 83 are made of sound-absorbing material. A groove 84 is provided between two sound-absorbing balls 83. The groove 84 is used to increase the diffuse reflection of sound, so that the noise is transmitted between the protective cover 8 and the main body 1 of the weft feeder and absorbed by the sound-absorbing balls 83, so as to achieve noise reduction of the weft feeder.

[0028] The working process of the utility model is as follows: when the weft storage device for a water jet loom is used, first, a fixing seat 81 is connected to one side of the protective cover 8 by welding, the protective cover 8 is installed on the support base 11 by means of mounting bolts 82 through the fixing seat 81, and the installation method is threaded installation, the fixing seat 81 is installed on the support base 11 by means of mounting bolts 82, and at the same time, the protective cover 8 is sleeved on the upper outer end of the weft storage device body 1 to realize the combination of the protective structure and the weft storage device body 1, and the protective cover 8 is made of high-strength stainless steel. Under the condition, the protective cover 8 is used to protect the weft feeder body 1 to prevent the weft feeder from being damaged by falling objects from above. Afterwards, the driving motor 4 and the winding body 5 inside the weft feeder body 1 will generate noise when working and rotating. Since the protective cover 8 is completely placed above the weft feeder body 1, and the sound-absorbing ball 83 is located at an appropriate position above the weft feeder body 1, the groove 84 is used to increase the diffuse reflection of the sound, so that the noise is transmitted between the protective cover 8 and the weft feeder body 1 and absorbed by the sound-absorbing ball 83, so as to achieve noise reduction of the weft feeder.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
