Description

An automatic tensioning device for an electronic jacquard machine

technical field

The utility model relates to an automatic tensioning device for an electronic jacquard machine, which belongs to the technical field of electronic machinery.

Background technique

The tensioning device is mainly used to adjust the tightness of transmission tools such as belts and sprockets. At present, the tensioning device used in electronic jacquard machines is generally adjusted manually. The second is that if the tightness of the chain is not adjusted in time, the chain will be stretched and damaged, and the two sprockets will not be synchronized, causing the opening of the jacquard to be unclear.

In view of this, the inventor studies this, and specially develops an automatic tensioning device for electronic jacquard machines, and this case results from this.

Utility model content

The purpose of the utility model is to provide an automatic tensioning device for an electronic jacquard machine, which can automatically tension the chain, improve production efficiency, reduce production cost, and solve the problem of unclear openings.

In order to achieve the above object, the solution of the present utility model is:

An automatic tensioning device for an electronic jacquard machine, comprising a sprocket, a bearing, a sprocket shaft, a slider, an inner wall panel, an outer wall panel, a guide rail, a spring, a fixing seat and a spring guide shaft, wherein the fixing seat is fixedly mounted on Between the inner wall panel and the outer wall panel, the spring guide shaft is fixed on the fixed seat, the inner wall panel and the outer wall panel are further installed with a guide rail, and a slider is slidably installed on the guide rail, and the sprocket shaft is connected with the slider through a screw One end of the spring is hung on the slider, the other end is fixed on the spring guide shaft, and the sprocket is installed on the sprocket shaft through the bearing.

Preferably, the automatic tensioning device further includes an adjusting nut installed at the lower part of the center of the inner wall panel for adjusting the length of the spring and further controlling the tension of the spring.

The working principle of the automatic tensioning device of the electronic jacquard machine is that the automatic tensioning device is installed on the chain used to connect the driving sprocket and the driven link of the electronic jacquard machine. The slider can reciprocate in the guide rail along with the tension of the chain, thereby driving the sprocket to reciprocate, so as to achieve the purpose of automatically adjusting the tightness of the chain. The automatic tensioning device of the electronic jacquard machine described in the utility model adopts spring automatic tensioning, which not only saves labor and time, improves production efficiency, but also makes the chain not easy to be damaged, has a low failure rate, prolongs the service life, reduces production cost and maintenance cost.

The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Description of drawings

Fig. 1 is the installation structural diagram of the electronic jacquard automatic tensioning device of the present embodiment;

Fig. 2 is a sectional view taken along line A-A of Fig. 1 .

Detailed ways

As shown in Figure 1-2, an automatic tensioning device for an electronic jacquard machine includes a sprocket 7, a bearing 8, a sprocket shaft 9, a slider 11, an inner wall panel 6, an outer wall panel 10, a guide rail 12, a spring 13, Fixed seat 14, spring guide shaft 15, wherein, said fixed seat 14 is fixedly installed between the inner wall panel 6 and the outer wall panel 10, the spring guide shaft 15 is fixed on the fixed seat 14, the inner wall panel 6 and the outer wall panel 10 are equipped with a guide rail 12, the guide rail 12 is slidingly installed with a slider 11, the sprocket shaft 9 is connected with the slider 11 through a screw 16, one end of the spring 13 is hung on the slider 11, and the other end is fixed on the spring guide shaft 15 On, the sprocket 7 is installed on the sprocket shaft 9 through the bearing 8. The automatic tensioning device further includes an adjusting nut installed at the lower part of the center of the inner wall panel 6 for adjusting the length of the spring 13 and further controlling the tension of the spring 13 .

The automatic tensioning device 5 described in this embodiment is installed on the chain 2 for connecting the driving sprocket 1 of the electronic jacquard machine and the first driven sprocket 3 and the second driven sprocket 4, and the sprocket 7 and the chain 2 Engaging, the automatic tensioning device 5 can make the slider 11 reciprocate in the guide rail 12 along with the tightness of the chain 2 under the action of the spring 13, thereby driving the sprocket 1 to reciprocate, so as to achieve the purpose of automatically adjusting the tightness of the chain 2. The automatic tensioning device of the electronic jacquard machine described in the utility model adopts spring automatic tensioning, which not only saves labor and time, improves production efficiency, but also makes the chain not easy to be damaged, has a low failure rate, prolongs the service life, reduces production cost and maintenance cost.

The above-mentioned embodiments and drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present utility model.
