Technical Field

The utility model belongs to the technical field of the loom, in particular to loom feed carrier of adjustable clamp force.

Background

The textile machine is called a textile machine, a weaving machine, a cotton spinning machine and the like, the ancient textile machine is a weaving machine driven by manpower, the textile machine is a tool for processing raw materials such as threads, silks, hemp and the like into silk threads and then weaving the silk threads into cloth, and the development of the ancient and modern textile technological processes and equipment is designed due to textile raw materials, so that the raw materials have an important position in the textile technology, a yarn guide mechanism of the textile machine is a component on the textile machine and used for conveying the cloth, the cloth is prevented from being loosened in the conveying process, but the clamping force can not be adjusted by the yarn guide mechanism of the existing textile machine.

Disclosure of Invention

The utility model aims at overcoming the shortcoming that the prior art can not adjust the clamp force, providing a loom feed carrier of adjustable clamp force.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a yarn guide mechanism of a loom capable of adjusting clamping force comprises an upper roller and a lower roller which are arranged up and down, and further comprises a guide cylinder body rotationally connected to two ends of the upper roller, a lifting block positioned in the guide cylinder body, a spring with the upper end connected to the lifting block, a U-shaped support positioned below the lower roller, a lifting cylinder used for lifting the U-shaped support, guide shafts positioned at two ends of the upper roller, and a rotating mechanism used for rotating the guide shafts; the guide shaft penetrates through the end part of the U-shaped support and is in sliding connection with the U-shaped support, two ends of the U-shaped support are in rotating connection with the end part of the lower roller, the lower end of the spring is connected to the lower end of the cavity of the guide cylinder body, the guide shaft penetrates through the guide cylinder body and is in sliding connection with the guide cylinder body, and the upper end of the guide shaft is provided with threads and is in threaded fit with the lifting block. Through the rotation of the rotating shaft, the left adjusting lifting block adjusts the compression amount of the spring, and therefore the adjustment of the clamping force is achieved.

Preferably, the rotating mechanism comprises a first bevel gear fixedly connected to the end of the guide shaft, a rotating shaft, a second bevel gear located at both ends of the rotating shaft and matched with the first bevel gear, and a motor for rotating the rotating shaft.

Preferably, the lift cylinder is an electric cylinder.

The utility model has the advantages that: the utility model provides a loom feed carrier of adjustable clamp force. Through the rotation of the rotating shaft, the left adjusting lifting block adjusts the compression amount of the spring, and therefore the adjustment of the clamping force is achieved.

Drawings

Fig. 1 is a schematic view of the present invention.

In the figure: the device comprises a guide cylinder body 1, an upper roller 2, a lower roller 3, a U-shaped support 4, a lifting cylinder 5, a guide shaft 6, a lifting block 7, a spring 8, a first bevel gear 9, a rotating shaft 10 and a second bevel gear 11.

Detailed Description

The invention will be further explained in detail with reference to the drawings and the following detailed description:

example (b):

referring to fig. 1, a yarn guide mechanism of a loom capable of adjusting a clamping force comprises an upper roller 2 and a lower roller 3 which are arranged up and down, and further comprises a guide cylinder body 1 rotatably connected to two ends of the upper roller 2, a lifting block 7 positioned in the guide cylinder body 1, a spring 8 with the upper end connected to the lifting block 7, a U-shaped support 4 positioned below the lower roller 3, a lifting cylinder 5 for lifting the U-shaped support 4, a guide shaft 6 positioned at two ends of the upper roller 2, and a rotating mechanism for rotating the guide shaft 6. The lift cylinder 5 is an electric cylinder.

The guide shaft 6 penetrates through the end part of the U-shaped support 4 and is in sliding connection with the U-shaped support 4, two ends of the U-shaped support 4 are rotatably connected with the end part of the lower roller 3, the lower end of the spring 8 is connected to the lower end of the cavity of the guide cylinder body 1, the guide shaft 6 penetrates through the guide cylinder body 1 and is in sliding connection with the guide cylinder body 1, and the upper end of the guide shaft 6 is provided with threads and is in threaded fit with the lifting block 7.

The rotating mechanism comprises a first bevel gear 9 fixedly connected at the end part of the guide shaft 6, a rotating shaft 10, a second bevel gear 11 positioned at the two ends of the rotating shaft 10 and matched with the first bevel gear 9, and a motor for rotating the rotating shaft 10.

Principle of embodiment:

when the motor is operated, the rotating shaft 10 rotates, the second bevel gear 11 rotates, the first bevel gear 9 rotates, the guide shaft 6 rotates, the lifting block 7 moves downward, and the spring 8 shortens, thereby increasing the clamping force between the upper roller 2 and the lower roller 3. When the clamping force needs to be reduced, the motor runs reversely, the lifting block 7 moves upwards, the spring 8 extends, the elastic force of the spring 8 is reduced, and the clamping force is reduced.

The electric cylinder can lift the height of the lower roller 3 up and down.

In addition, when it is required to separate the upper and

lower rolls

2 and 3, the elevating block 7 is moved upward until the elevating block 7 is moved to the upper end of the cavity in the guide cylinder 1, and then the elevating block 7 continues to be moved upward to lift the guide cylinder 1 upward, thereby separating the upper and

lower rolls

2 and 3.
