[0002] In the textile production process, the quality and performance of yarn directly affect the quality of final textile product. And the stability of yarn tension is crucial in the process of conveying, winding and other processes. If the yarn tension is uneven, it will lead to uneven thickness of yarn, and problems such as broken yarn and uneven density of fabric may occur in subsequent weaving.

[0003] Traditional yarn tension adjusting device is extremely inconvenient to adjust. On the one hand, the adjustment operation of many devices relies on manual operation, such as changing tension by rotating nut, adjusting bolt and other methods. In large-scale production scenarios, frequent adjustment requirements greatly increase the labor intensity of workers, and manual operation is prone to adjustment errors, making it difficult to accurately control tension. On the other hand, even if some devices have automatic adjustment function, the setting and modification process of adjustment parameters is very complicated, often requiring operators to access the equipment control system and adjust through complex menu options and code input. This not only requires operators to have high professional technical level, but also in the production process, if the tension needs to be temporarily adjusted to adapt to different batches of yarn or production conditions, this complicated adjustment process will waste a lot of time, seriously affecting production efficiency. At the same time, during production, transportation and storage, the surface of yarn is prone to contamination with dust, lint and other impurities. If these impurities are not cleaned in time, they will be embedded in the fabric during the weaving process, forming defects and reducing the appearance quality and performance of the textile product.

DETAILED DESCRIPTION

[0023] The embodiment of the utility model is further explained in connection with the drawings.

[0024] Embodiment:

[0025] As Figures 1-4 shown, a kind of yarn tension adjusting device for weaving, including base 1 and installation vertical plate 2 of being installed on base 1 and the three transmission rollers 3 of being connected on installation vertical plate 2, center transmission roller 3 is equipped with adjusting assembly 4, adjusting assembly 4 includes adjusting mechanism 40 and cleaning mechanism 41;

[0026] The adjusting mechanism 40 comprises an adjusting motor 401, an adjusting screw rod 402 and a pressure sensor 404, the adjusting motor 401 is connected to the mounting stand 2, the adjusting screw rod 402 is installed on the output shaft of the adjusting motor 401, the adjusting screw rod 402 is connected with an adjusting moving plate 403 which is attached to the mounting stand 2, the adjusting moving plate 403 is located at the position of one end of the center conveying roller 3, the adjusting moving plate 403 is connected with the conveying roller 3 through a rotating shaft, the pressure sensor 404 is installed on the surface of a placing groove which is opened on the conveying roller 3, two symmetrical adjusting first return springs 405 are further connected to the surface of the placing groove, a pressure transmission bottom plate 406 is further connected to the free end of the two adjusting first return springs 405 which are away from the placing groove, the two adjusting first return springs 405 are respectively located at the positions of the two sides of the pressure sensor 404, the two ends of the two adjusting first return springs 405 are respectively connected with the placing groove and the pressure transmission bottom plate 406, at least four positioning inserting rods are fixedly installed on the surface of the placing groove, the positioning inserting rods penetrate through the surface of the pressure transmission bottom plate 406, and a pressure pressing plate 407 is further installed on the pressure transmission bottom plate 406.

[0027] The working principle of the above technical scheme is as follows:

[0028] When the yarn is wound around the center conveying roller 3, the tension of the yarn will generate a force on the conveying roller 3, since one end of the conveying roller 3 is connected with the output shaft of the adjusting motor 401 through the adjusting moving plate 403, the force will be transmitted to the pressure transmission bottom plate 406, if the yarn tension is too large, the pressure transmission bottom plate 406 will overcome the elastic force of the adjusting first return spring 405 and move towards the placing groove, thereby pressing the pressure sensor 404, the positioning inserting rods ensure the stability of the pressure transmission bottom plate 406 during the movement, so that it will not deviate, the pressure sensor 404 will monitor the pressure in real time, when the pressure reaches the preset threshold value, it means that the yarn tension exceeds the normal range, the pressure sensor 404 will transmit the signal to the control system, after receiving the signal, the control system will start the adjusting motor 401.

[0029] After the adjusting motor 401 is started, the output shaft drives the adjusting screw rod 402 to rotate, since the adjusting moving plate 403 is connected with the adjusting screw rod 402 and attached to the mounting stand 2, the rotation of the adjusting screw rod 402 will make the adjusting moving plate 403 move up and down along the surface of the mounting stand 2, since the adjusting moving plate 403 is connected with the conveying roller 3 through a rotating shaft, the movement of the adjusting moving plate 403 will drive one end of the conveying roller 3 to move up and down, thereby changing the angle and position of the yarn on the conveying roller 3, and realizing the adjustment of the yarn tension.

[0030] By setting the adjusting motor 401, the pressure sensor 404, and the adjusting first reset spring 405 to cooperate with each other, when the yarn passes through the center transmission roller 3, the tension of the yarn makes the pressure transmission bottom plate 406 overcome the elastic force of the adjusting first reset spring 405 to press the pressure sensor 404, and the pressure sensor 404 monitors the pressure in real time. Once the preset threshold is reached, a signal is transmitted to the control system, without frequent manual intervention, the automatic adjustment function is realized, the production efficiency is greatly improved, and the manual operation error and labor intensity are reduced.

[0031] In another embodiment, as shown in Figure 3 and Figure 4 The cleaning mechanism 41 includes a cross plate 410, a protective rubber pad 411, and four plug plates 412. The cross plate 410 is arranged on the center transmission roller 3, and the opposite surfaces of the cross plate 410 and the pressure pressing plate 407 are each provided with a protective rubber pad 411. The plug plates 412 are arranged in two groups, and each group of plug plates 412 is arranged on the pressure pressing plate 407 and the cross plate 410 through screws. The cleaning mechanism 41 further includes two mounting blocks 413, a positioning rod 414, and a second reset spring 415. The two mounting blocks 413 are symmetrically connected to the cross plate 410. The positioning rod 414 is arranged on the slot surface of the transmission roller 3. The second reset spring 415 is arranged in compression between the slot and the mounting block 413. The opposite surfaces of the two protective rubber pads 411 are arc-shaped, and the surfaces of the two protective rubber pads 411 are each provided with a plurality of cleaning grooves.

[0032] When the yarn is transmitted on the center transmission roller 3, it will contact the protective rubber pads 411 on the pressure pressing plate 407 and the cross plate 410. Since the opposite surfaces of the two protective rubber pads 411 are arc-shaped, they can better fit the surface of the yarn. During the movement of the yarn, the cleaning grooves on the surface of the protective rubber pad 411 will scrape the impurities on the surface of the yarn. After the impurities are scraped off, they will remain in the cleaning grooves, thereby achieving the cleaning of the impurities on the surface of the yarn.

[0033] The mounting block 413 is symmetrically connected to the cross plate 410. The positioning rod 414 is arranged on the slot surface of the transmission roller 3. The second reset spring 415 is arranged in compression between the slot and the mounting block 413. When the thickness of the yarn changes or the position of the yarn fluctuates during transmission, the pressure of the yarn on the protective rubber pad 411 will change. At this time, the cross plate 410 will move in the direction of the positioning rod 414 under the action of the second reset spring 415 through the mounting block 413. The second reset spring 415 can not only ensure that the protective rubber pad 411 always maintains appropriate contact pressure with the yarn, but also avoid damaging the yarn due to excessive pressure. The plug plates 412 are arranged on the pressure pressing plate 407 and the cross plate 410 through screws, which ensures the stability of the installation of the protective rubber pad 411 and prevents it from moving during the cleaning of impurities.

[0034] Through setting the mounting block 413, the positioning rod 414 and the second reset spring 415, when the thickness, position and the like of the yarn change, the cross plate 410 can be self-adaptively adjusted in position under the action of the second reset spring 415, meanwhile, the protective rubber pad 411 and the cleaning grooves on the surface thereof can effectively scrape and collect the impurities on the surface of the yarn when the yarn passes between the protective rubber pad 411, thus realizing the good adaptability of the cleaning mechanism 41 to the yarn under different working conditions.

[0035] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
