Description

Technical Field

[0001] The invention relates to the technical field of textile processing, and more particularly to an improved front roller of a roving frame. Background Art

[0002] In the structure of the roving frame, a layer of leather ring is wrapped around the front roller. This component is made of leather or high-performance synthetic rubber and has a ring-shaped structure. It is an indispensable key component of the roving frame. The leather ring plays a vital role in the roving frame. It works closely with the rollers to undertake the complex tasks of controlling fiber movement and realizing yarn drawing and twisting.

[0003] Rollers, usually made of metal materials, form a complementary pair with the leather rings. However, in actual operation, due to the continuous contact and friction between the leather rings and the rollers, the leather rings will gradually wear and become thinner. This wear not only changes the original shape of the leather rings, but also has a profound impact on the coordination between them and the rollers.

[0004] When the leather ring is worn and becomes thinner, the extrusion pressure between it and the roller decreases, resulting in a corresponding reduction in the contact area between the two. This change directly affects the stability of the friction force boundary, making the movement state of the fiber in the drafting process no longer stable, and the force distribution of the fiber becomes uneven, which in turn affects the uniformity and strength of the yarn, greatly reducing the overall quality of the yarn.

[0005] What is more serious is that the wear and thinning of the leather ring also weakens its grip on the fiber. The leather ring that was originally tightly wrapped around the fiber can no longer provide sufficient support and grip due to wear, causing the fiber to slip or break more easily during the drafting process. This situation not only aggravates the unevenness of the yarn, but also significantly increases the breakage rate, causing many inconveniences and losses to production. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide an improved front roller of the roving machine, which can automatically adjust the extrusion pressure between the leather ring and the roller when the extrusion pressure between the leather ring and the roller is less than a preset pressure value. This can ensure that the pressure between the leather ring and the roller is always in an optimal state, avoid the problem of reduced twisting quality due to leather ring wear, and ensure the twisting effect of the fiber strips and the product quality.

[0062] The control assembly also includes a baffle 9, which is fixedly mounted on the upper end surface of the support plate 2 and is arranged at a position close to the side surface of the drive motor 6, a triangular block 14 is fixedly mounted on the side surface of the baffle 9, and the triangular block 14 is mounted on the side of the baffle 9 facing away from the drive motor 6, and a prismatic column 12 is arranged on one side of the triangular block 14; a column limiting plate 11, which is sleeved on the side surface of the prismatic column 12, and one end of the column limiting plate 11 is fixedly connected to the mounting frame 1; a threaded column 13, which is arranged in the prismatic column 12, and the threaded column 13 is threadedly connected to the inner wall of the prismatic column 12, and one end of the threaded column 13 passes through the prismatic column 12 and extends to the outside; a servo motor 10, and the output shaft of the servo motor 10 is fixedly connected to the threaded column 13;

[0063] The detection component also includes an extrusion rod 16, which is arranged inside the leather roller 7 and one end of which extends out of the leather roller 7 to the outside. The extrusion rod 16 is located outside and is flush with the surface of the leather roller 7. The pressure sensor 19 is installed inside the leather roller 7, and the pressure sensor 19 is located at one end of the extrusion rod 16; a conductive slip ring 17, which is installed at one end of the leather roller 7 away from the drive motor 6, and the conductive slip ring 17 is electrically connected to the pressure sensor 19.

[0064] By adopting the above technical scheme, the fiber passes between the leather ring 8 and the roller 18, and then the roller 18 is driven to rotate by the transmission component in the roving machine. The spinning machinery in the prior art generally drives the leather ring 8 to rotate by rotating the roller 18. The present invention provides a method in which the rotation of the leather roller 7 can be controlled by the driving motor 6. The rotation of the leather ring 8 is controlled by the leather roller 7. This method can achieve precise control of the rotation speed and position of the leather roller 7, thereby improving the uniformity and strength of the yarn.

[0065] Initially, the extrusion pressure between the leather ring 8 and the roller 18 is set to a preset pressure threshold. Because the leather ring 8 is deformable, when the leather ring 8 and the roller 18 are squeezed against each other, the deformation of the leather ring 8 will squeeze the squeezing rod 16, and the squeezing rod 16 will squeeze the pressure sensor 19 after being squeezed. The squeezing force between the leather ring 8 and the roller 18 can be detected by the pressure sensor 19. When the leather roller 7 and the leather ring 8 rotate, the external power supply equipment can supply power to the pressure sensor 19 through the conductive slip ring 17. By installing the conductive slip ring 17, the problem of the transmission wire being entangled or twisted due to rotation can be avoided. When the leather ring 8 is worn, it will become thinner, the extrusion force between the leather ring 8 and the roller 18 will become smaller, and the pressure value monitored by the pressure sensor 19 will become smaller. When the detected pressure value is lower than the preset pressure threshold, the servo motor 10 is controlled to drive the threaded column 13 to rotate. When the threaded column 13 rotates, it will drive the prismatic column 12 to gradually approach the triangular block 14. Because the prismatic column 12 is worn on the limiting column plate 11, it can limit the prismatic column 12 from rotating. Therefore, the threaded column 13 can drive the prismatic column 12 to move left and right when rotating forward and reverse. When the prismatic column 12 is close to the triangular block 14, it will squeeze the triangular block 14, and the triangular block 14 will move downward after being squeezed. When the triangular block 14 moves downward, it will drive the baffle plate 9 and the support plate 2 to move downward synchronously. When the support plate 2 moves downward, it will compress the first spring 15. At the same time, the support plate 2 will also drive the baffle plate 9 and the leather roller 7 to move downward together. The downward movement of the leather roller 7 will drive the leather ring 8 to squeeze the roller 18. When the pressure sensor 19 detects that the pressure reaches the preset pressure threshold, the servo motor 10 is powered off at the same time, and the control of the movement of the prismatic column 12 is stopped. This can ensure that the pressure between the leather ring 8 and the roller 18 is always in the best state, avoiding the problem of reduced twisting quality due to wear of the leather ring 8, and ensuring the twisting effect of the fiber strips and the product quality.

[0066] In some embodiments of the present invention, a computing component is installed outside the mounting frame 1, and the computing component includes a processing unit, and the processing unit is used to calculate the remaining use time of the leather ring 8 according to the spacing and working time of each downward movement of the leather ring 8; the computing component also includes: a photoelectric sensor 20, the photoelectric sensor 20 is installed on the lower end surface of the support plate 2, and the photoelectric sensor 20 is set at a position directly above the detection plate 21;

[0067] The distance of each downward movement of the apron 8 is measured by the photoelectric sensor 20, and the distance of each downward movement of the apron 8 is recorded by the processing unit. The processing unit also records the corresponding working time of each downward movement of the apron 8, and calculates the remaining thickness of the apron 8 according to the initial thickness of the apron 8 and the distance of each downward movement of the apron 8;

[0068] The wear amount of the apron 8 per unit time is calculated by recording each downward movement distance of the apron 8 and the corresponding working time. The remaining use time of the apron 8 is calculated according to the wear amount of the apron 8 per unit time and the remaining thickness of the apron 8 .

[0069] By adopting the above technical solution, the thickness of the apron 8 is determined in advance, and the photoelectric sensor 20 measures the distance between the photoelectric sensor 20 and the detection plate 21 in advance. The distance that the apron 8 moves downward each time due to wear is the same as the distance that the photoelectric sensor 20 moves downward. The change in the distance detected by the photoelectric sensor 20 from the detection plate 21 is the distance that the apron 8 moves downward. The processing unit records the distance that the apron 8 moves downward each time, and the remaining thickness of the apron 8 can be calculated based on the initial thickness of the apron 8 and the distance that the apron 8 moves downward each time. Assuming that the initial thickness of the apron 8 is , the distance of each downward movement is ,in Expressed as the number of downward movements, the remaining thickness of the apron 8 It can be expressed as: ,in Expressed as the number of downshifts.

[0070] The processing unit will record the corresponding working time of the leather ring 8 each time it moves down. According to the recorded downward distance of the leather ring 8 each time and the corresponding working time, the wear amount of the leather ring 8 per unit time can be calculated. First, the total wear amount of the leather ring 8 is calculated as , , according to the total wear amount The total working time of the leather ring 8 is , the average wear rate of apron 8 can be calculated , , according to the average wear rate of the apron 8 and the remaining thickness of the apron 8 , the remaining thickness of the leather ring 8 can be calculated to determine the time it can be used. , , the obtained data information and the data information detected by the sensor can be transmitted to the operation panel of the roving machine through wire, so that the staff can directly know the remaining service life of the leather ring 8, the current thickness and remaining thickness of the leather ring 8 on the operation panel, so that the staff can timely understand the current status of the leather ring 8. By real-time monitoring of the wear of the leather ring 8, the wear problem can be discovered and dealt with in time, the downtime caused by damage to the leather ring 8 can be reduced, and the equipment maintenance efficiency can be improved. By reasonably predicting the replacement time of the leather ring 8, the number of unnecessary replacements of the leather ring 8 can be reduced, and the production cost can be reduced. Real-time monitoring of the wear of the leather ring 8 can timely discover potential safety hazards, such as the breakage of the leather ring 8, so that corresponding measures can be taken to avoid the occurrence of safety accidents.

[0071] In some embodiments of the present invention, the roller 23 is arranged just above the leather ring 8; the elastic hooks 24 are arranged in multiple groups, and the multiple groups of elastic hooks 24 are evenly distributed on the side surface of the roller 23;

[0072] A fixed plate 22 is installed on the upper end surface of the support plate 2; a mounting tube 31 is rotatably installed on the support plate 2, and a rectangular groove is provided inside the mounting tube 31; a square rod 29 is inserted into the rectangular groove, and the right end of the square rod 29 is fixedly connected to the roller 23.

[0073] By adopting the above technical solution, because the leather ring 8 is usually made of rubber or other synthetic materials, the leather ring 8 is subjected to greater tension and pressure when in use, which makes the fiber material more easily compressed and adhered to the surface of the leather ring 8. When the fiber material is stuck on the leather ring 8 of the present invention, the fiber material will rotate with the leather ring 8. As the fiber material accumulates, the thickness of the leather ring 8 will increase. When the fiber material moves to the upper end of the leather ring 8, it will contact the elastic hook 24. The elastic hook 24 will hook the fiber material on the leather ring 8 and drive the roller 23 to rotate at the same time, so that the next group of elastic hooks 24 will contact the fiber material on the leather ring 8. In this way, the sticky fiber material on the leather ring 8 can be effectively removed, and the twisting effect of the leather ring 8 and the roller 18 on the fiber can be ensured.

[0074] In some embodiments of the present invention, a push rod 25 is provided inside the roller 23, and the right end of the push rod 25 movably passes through the roller 23 and extends to the outside; a cotton doffing hole 26, the number of the cotton doffing holes 26 corresponds to the number of the elastic hooks 24, the cotton doffing holes 26 are opened on the outer surface of the roller 23, and the hook handle of the elastic hook 24 passes through the cotton doffing hole 26 and is fixedly connected to the push rod 25; a second spring 30, the second spring 30 is fixedly connected to the left end of the push rod 25, and the second spring 30 is provided in the square rod 29; a push sheet 27, the push sheet 27 is fixedly connected to the right end of the push rod 25; a finger sleeve 28, the finger sleeve 28 is fixedly connected to the right end of the roller 23.

[0075] By adopting the above technical solution, when it is necessary to clean the fiber material on the rotating roller 23, the square rod 29 is directly pulled out from the mounting tube 31, and then the operator's index finger and middle finger are inserted into the finger sleeve 28, and the thumb presses the push piece 27 to drive the push rod 25 to compress the second spring 30, and the push rod 25 will move toward the inside of the square rod 29. When moving, the push rod 25 will pull the hook handle of the elastic hook 24, so that the elastic hook 24 moves into the cotton doffing hole 26. The hook portion of the elastic hook 24 is restricted by the cotton doffing hole 26 and will change from the previous curved shape to a straight strip shape and enter the cotton doffing hole 26. At this time, the elastic hook 24 is separated from the fiber cotton, and the operator can easily clean the fiber cotton on the rotating roller 23. After cleaning, the push piece 27 is sent away, the second spring 30 is reset and drives the push rod 25 to move in the opposite direction. At this time, the elastic hook 24 will extend out of the cotton doffing hole 26. The elastic hook 24 is made of elastic material and the elastic hook 24 will return to its original state.

[0076] In some embodiments of the present invention, the square rod 29 is made of magnetic conductive material, specifically iron and iron alloy material, and the mounting tube 31 is made of permanent magnetic material, such as cobalt, nickel or cobalt-nickel alloy material. This allows the square rod 29 to be magnetically coupled with the mounting tube 31, thereby increasing the stability of the square rod 29 after installation and facilitating disassembly when cleaning the fiber cotton on the rotating roller 23.
