Description

Dropper

Technical Field

A dropper relates to the field of textile machinery, in particular to a dropper with a warp breakage protection and indication function in the working of textile machinery.

Background

The warp yarn breaking of the loom is an inevitable problem in production in the textile industry, and at the present stage, each loom manufacturer or textile enterprise adds a warp stopping sheet on the loom to avoid the problem that the loom does not stop to continue working after the warp yarn is broken in production. However, the number of warp threads of the weaving machine for producing large-width fabrics is hundreds of warp threads, and the conventional dropper only has the protection function of power-off shutdown after warp breakage and cannot give the number and the specific direction of the broken warp threads. After the large-width loom is broken and stops, the broken warp position needs to be identified manually by visual inspection and touching a dropper with hands, if a plurality of warps are broken at different positions, the phenomenon that the loom cannot be started and stopped can be caused by manual identification due to time and labor consumption and slight negligence, and the product delivery period and the yield of a textile enterprise can be seriously influenced.

Detailed Description

The dropper 1 of the present invention is integrally formed by a printed circuit board, and has a beam-passing hole 112 formed in the upper portion thereof, a warp-passing hole 113 formed in the middle portion thereof, and an opening structure 114 formed in the lower portion thereof, as shown in fig. 1. The plurality of warp stop sheets 1 are threaded and hung on a loom warp stop beam 2 through beam penetrating strip holes 112, and the warp stop beam 2 comprises a metal U-shaped outer layer body 21, a middle insulator 22 and a metal strip inner layer body 23. The warp 3 passes through the warp through hole 113 of the drop wire 1 and supports the drop wire 1, and the upper end of the beam through hole 112 of the supported drop wire 1 is separated from the top end of the drop wire 2. In order to prevent the swing amplitude of the drop wire 1 after being lifted up from being too large, the opening structure 114 is internally provided with a swing stop rod 3.

In a first embodiment of the drop wire 1 of the present invention, as shown in fig. 2, the upper end of the beam-penetrating hole 112 of the drop wire 1 is provided with

metal contact points

12, 13, 14 and a light-emitting body 11, and the light-emitting body 11 is connected with the

metal contact points

12, 13, 14 through

electric conductors

15, 16, 17.

Preferably, in order to increase the contact area of the

metal contacts

12, 13, 14, the

metal contacts

12, 13, 14 of the second embodiment of the drop wire 1 of the present invention shown in fig. 3 can be configured as

metal strip plates

12a, 13a, 14 a.

More preferably, as shown in fig. 2, 3 and 4, the top end of the beam penetrating hole 112 of the dropper 1 can be made into an inclined plane with an acute angle 111, and the third embodiment of the dropper 1 of the present invention, as shown in fig. 4, two

metal strip plates

12a and 13a are respectively disposed on two connected edges of the upper end of the beam penetrating hole 112 of the dropper 1, which form the acute angle 111.

In the three specific embodiments, the metal contact points or the metal strip plates, the electric conductors and the light-emitting bodies (11) are arranged on the same surface of the dropper 1.

In order to enhance the light emitting effect of the drop wire 1 in the above three embodiments, a light emitting body 11 is additionally arranged on the other surface of the drop wire 1 arranged on the light emitting body 11. The two luminous bodies 11 are connected in series with the metal contact points or the metal strip plates and the electric conductors.

In order to reduce the influence of the circuit on the device after the two light emitters 11 are serially connected and the single light emitter 11 is damaged, it is preferable that a group of electrical conductors are additionally connected to the same surface of the additional light emitter 11, and the additional light emitter 11 and the additional group of electrical conductors are separately connected to the metal contact points or the metal strip plates.

Preferably, in order to enhance the oxidation resistance of the metal contact points, the metal strip plates and the electric conductors in the three embodiments, and improve the service life of the dropper and the sensitivity of electric contact, the surfaces of the metal contact points or the metal strip plates and the electric conductors are coated with gold-plated coatings.

The light emitting body (11) in all the above embodiments is specifically an LED lamp or an LED.

The working principle of the dropper of the utility model is as follows.

As shown in fig. 1, one end of the metal strip inner layer body 23 of the warp stop beam 2 is electrically connected with the positive pole of the loom controller, and one end of the metal U-shaped outer layer body 21 is connected with the negative pole of the loom controller. Because the insulator 22 is arranged between the metal U-shaped outer layer body 21 and the metal strip-shaped inner layer body 23 of the dropper beam 2, no electric loop signal is transmitted to the loom controller by the metal strip-shaped inner layer body 23 which is connected with the power supply of the loom controller. (in this example, the positive electrode of the metal strip inner layer body 23 is electrified for example) when the warp 3 of the loom is pulled off by the pulling force shown in fig. 5, the dropper 1 falls downward. The metal strip plate 13a of the dropper 1 shown in fig. 6 after dropping comes into contact with the metal strip inner 23 of the dropper beam 2. Due to the inclined plane design of the top acute angle 111 of the beam penetrating hole 112 of the dropper beam 2, the metal strip plate 12a of the dropper 1 is fully contacted with the metal U-shaped outer layer body 21 of the dropper beam 2. The current of the loom controller passes through the metal strip inner body 23, the metal strip plate 13a and the conductor 16, when the current passes through the luminous body 11 and lights the luminous body, the current loop is conducted back to the cathode of the loom controller through the conductor 15, the metal strip plate 12a and the metal U-shaped outer layer body 21, and the loom controller cuts off the external power supply of the loom and sends an alarm signal.

The above is the detailed introduction of the power failure piece provided by the embodiment of the present invention, and to the general technical personnel in the field, the idea of the embodiment of the present invention has a change part on the concrete implementation and the application range. In summary, the content of the present specification should not be understood as a limitation of the present invention, and any changes made according to the design concept of the present invention are all within the protection scope of the present invention.
