Description

Double fastening hoop for warp beam of warp knitting machine

technical field

The utility model relates to the technical field of warp knitting machines, in particular to a double fastening hoop for warp beams of warp knitting machines.

Background technique

In the warp knitting machine, the warp beam is driven by the rotating shaft. In order to reduce its own weight, the rotating shaft is generally hollow. How to better fix the warp shaft on the rotating shaft has always been a problem that technicians need to overcome. Difficulties, the traditional fastening method is mainly to connect the warp beam and the rotating shaft through a set key, and set hoops at both ends of the warp beam, the hoops are tightened before the shaft and then fastened with bolts , that is: after the screw passes through the two connecting ears in the hoop, screw the nut on the screw, and the distance between the connecting ears is shortened by the shoulder on the nut and the screw pressing the two connecting ears, so as to realize the connection with the rotating shaft. Then fix the hoop on the warp beam through bolts; however, the cooperation between the screw and the nut is prone to the phenomenon of nut detachment. After a long time, the nut is easy to fall off from the screw, causing the two connecting ears to separate, and the hoop is loose Take off, finally cause the separation of warp beam and rotating shaft, make warp beam stop rotating, affect the use of warp knitting machine, reduce the efficiency of warp knitting.

Utility model content

The technical problem to be solved by the utility model is: in order to overcome the hoop used in the warp knitting machine in the prior art, the two connecting ears are fastened with screws, but the cooperation between the screws and the nuts is prone to the phenomenon that the nuts come off the wire, and it takes a long time. Finally, the nut is easy to fall off from the screw, resulting in the separation of the two connecting ears, the loosening of the hoop, and finally the separation of the warp beam and the rotating shaft, so that the warp beam stops rotating, which affects the use of the warp knitting machine and reduces the efficiency of warp knitting. The invention provides a double fastening hoop for a warp beam of a warp knitting machine.

The technical solution adopted by the utility model to solve the technical problem is: a double fastening hoop for the warp beam of a warp knitting machine, including a hoop plate, a screw and a nut matched with the screw, and the hoop plate is an open ring , the outer peripheral surface of the hoop plate is evenly distributed with a number of mounting holes, the inner peripheral surface of the hoop plate is provided with key grooves, and the two ends of the hoop plate are respectively fixedly installed with the first connecting ear and the second Connecting ears, the first connecting ear and the second connecting ear are arranged in parallel, the upper surface of the first connecting ear is provided with a threaded hole and a first counterbore coaxial with the threaded hole, the first A thread is provided on the inner peripheral surface of a countersunk hole, and the lower surface of the second connecting ear is provided with a through hole and a second countersink coaxial with the through hole, and the inner surface of the second countersink is The circumferential surface is also provided with threads, and the screw thread is installed in the threaded hole and passes through the through hole. The nut is threaded on the screw, the upper surface of the nut is provided with an annular protrusion, and the annular protrusion is threadedly engaged with the second counterbore.

In order to prevent the hoop from moving axially on the warp beam, a number of anti-slip protrusions are provided on the inner peripheral surface of the hoop plate.

The beneficial effects of the utility model are: the shoulder and the countersunk hole of the screw in the utility model are also fixed by threaded connection, which is one more fastening than the fixing of only the screw and the threaded hole, and can effectively prevent the screw from being connected to the second screw hole. The loosening of the first connecting ear; at the same time, the nut thread is installed on the second connecting ear and then connected with the screw thread. The thread cooperation between the nut and the second connecting ear makes the nut also tightened again, which can effectively prevent the nut from falling off. thread, so that the cooperation between the screw and the nut is firmer; the utility model uses a double fastening method to fasten the first connecting ear and the second connecting ear thread, so that the fastening method of the hoop is firmer, and the connection between the rotating shaft and the warp beam There is a relatively firm connection between them, which avoids the phenomenon that the warp beam stops rotating due to the loosening of the hoop, so that the warp knitting efficiency of the warp knitting machine is higher.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, a double fastening hoop for the warp beam of a warp knitting machine includes a hoop plate 1, a screw 2 and a nut 3 matched with the screw 2 as shown in Figure 4, and the hoop plate 1 is an opening There are three installation holes 4 evenly distributed on the outer circumference of the hoop plate 1, key grooves 5 are provided on the inner circumference of the hoop plate 1, and both ends of the hoop plate 1 are respectively fixed and installed. There are a first connecting ear 6 and a second connecting ear 7, the first connecting ear 6 is arranged parallel to the second connecting ear 7, the upper surface of the first connecting ear 6 has a threaded hole 8 and is connected with the The threaded hole 8 is coaxial with the first counterbore 9, the inner peripheral surface of the first counterbore 9 is provided with threads, and the lower surface of the second connecting ear 7 has a through hole 10 and is connected with the through hole. Hole 10 coaxial second countersunk hole 11, as shown in Figure 5, the inner peripheral surface of described second countersunk hole 11 is also provided with screw thread, and described screw 2 is threadedly installed in described threaded hole 8, And through the through hole 10, the outer peripheral surface of the shoulder 12 of the screw 2 is provided with a screw thread that is screwed with the first counterbore 9, and the nut 3 is screwed on the screw 2 , the upper surface of the nut 3 is provided with an annular protrusion 13, and the annular protrusion 13 is threadedly engaged with the second counterbore 11.
