Description

A head rack device capable of automatically adjusting tension

Technical Field

The utility model relates to the technical field of textiles, in particular to a headstock device capable of automatically adjusting tension.

Background technique

Warp knitting machines are widely used in the fabric processing and production process. They mainly unwind the yarn from the drum and send it into the machine body for weaving. Through the interweaving of warp and weft, they are processed into fabrics commonly used in daily life.

During the warp yarn feeding process of the warp knitting machine, it is necessary to control the tension of the warp yarn. The conventional mechanism is to install a brake device with a belt at one end of the warp shaft, and adjust the tightness of the brake belt to achieve the tension control of the warp yarn feeding. This method of tension adjustment will cause the problem of uneven tension of each warp head. Because in actual use, multiple groups of warps are feeding yarn at the same time, it is easy to cause uneven tension of each warp head, thereby affecting the quality of the woven fabric. Therefore, we propose a warp head frame device that can automatically adjust the tension to solve the above problem.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. In this embodiment, a head frame device capable of automatically adjusting tension includes two frame bases 1. Two sets of locking components are arranged above the two frame bases 1. An automatic head tension adjustment mechanism is arranged above the two frame bases 1.

Specifically, by providing a locking assembly, the purpose of adjusting one or more groups of disc head frames 4 to move and fix them is achieved, thereby improving the use efficiency. By providing an automatic disc head tension adjustment mechanism and utilizing the electromagnetic powder clutch 7, the user only needs to adjust the size of the excitation current to accurately control and transmit the required torque, and the tension of the disc head frame 4 can be accurately adjusted through the gear drive, while making the tension adjustment visual and uniform.

In this embodiment, the automatic adjustment of the disk tension mechanism includes two frames 2 fixedly installed on the top of four support plates 9, an electromagnetic powder clutch 7 is fixedly installed on the right side of the right frame 2, the output shaft of the electromagnetic powder clutch 7 passes through and extends to the left side of the right frame 2, a disk frame 4 is movably installed between the opposite sides of the two frames 2, and a warp shaft 5 with two ends passing through and extending to the outside of the two frames 2 is fixedly installed inside the disk frame 4, the outer surface of the warp shaft 5 is rotatably connected to the frame 2, a gear 1 3 is fixedly installed on the outer surface of the output shaft of the electromagnetic powder clutch 7, a gear 2 8 is fixedly installed on the outer surface of the warp shaft 5, the outer surface of the gear 1 3 is meshed with the outer surface of the gear 2 8, and mounting frames 10 are fixedly installed on the backs of the two frames 2, and the interiors of the two mounting frames 10 are detachably connected with a yarn guide roller component 6.

Among them, gear 1 3 and gear 2 8 are both located in the same vertical direction, and gear 1 3 is located below gear 2 8, so that the disk head frame 4 can rotate through the rotation of the gears.

Among them, the mounting frame 10 is in the shape of an 'Ω' placed on its side when viewed from the side, and the yarn guide roller component 6 includes a yarn guide roller and a rotor, and the rotor is rotatably mounted on the outer surface of the yarn guide roller, and the outer surface of the rotor is pressed against the inner surface of the mounting frame 10, which is convenient for the installation and use of the yarn guide roller.

It should be explained that the outer surface of the rotor is squeezed and fixed by the mounting frame 10 , and when the yarn guide roller rotates, the rotor does not rotate inside the mounting frame 10 .

Specifically, by providing an electromagnetic powder clutch 7 to adjust the magnitude of the exciting current, the required torque can be accurately controlled and transmitted, causing the gear 1 3 to drive the gear 2 8 to rotate, thereby rotating the warp shaft 5 and driving the disc head frame 4 for tension adjustment.

In this embodiment, the locking assembly includes a support plate 9 slidably connected to the top of the frame base 1, and a locking plate 11 is movably installed at the bottom of the support plate 9. The external thread connection of the locking plate 11 is connected to a torsion rod 12 with one end passing through and extending into the interior of the support plate 9.

Among them, the rack base 1 is I-shaped when viewed from the side, and the side of the clamping plate 11 close to the rack base 1 is in contact with the outer surface of the rack base 1. The support plate 9 is provided with a threaded hole that penetrates and extends to the outside thereof, and the threaded hole corresponds to the torsion bar 12, which facilitates the clamping plate 11 to squeeze and fix the rack base 1.

The torsion bar 12 is in an inverted "T" shape when viewed from the side, and the outer surface of the torsion bar 12 located outside the locking plate 11 is engraved with vertical edges to increase the friction with the hand and facilitate twisting.

Specifically, by providing a torsion bar 12, twisting it can drive the clamping plate 11 to move up and down, thereby achieving the effect of being installed and fixed with the rack base 1, thereby facilitating the installation and use of one or more groups of pan head racks 4, and because the rack base 1 is in a long strip shape, the pan head rack 4 can be controlled to be fixed and used in any position by clamping the clamping plate 11 and the support plate 9.

It should be noted that the electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

The working principle of the above embodiment is:

The disc head frame device which can automatically adjust the tension, when in use, controls the electromagnetic powder clutch 7 to rotate, drives the gear 1 3 to rotate the gear 2 8, that is, the warp shaft 5 rotates, and drives the disc head frame 4 to adjust the tension. By setting the torsion bar 12 and twisting the torsion bar 12 to disengage the support plate 9, the position adjustment of the frame base 1 can be completed at any position. After the adjustment, the support plate 9 can be squeezed and fixed by twisting the torsion bar 12 again, that is, the position of the frame base 1 is fixed, thereby achieving the effect of fixing the disc head frame 4. If there are multiple groups of disc head frames 4, they can be placed as needed and can be used after being fixed through the above operation.
