Description

Technical Field

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

[0002] In the structure of a roving frame, a layer of apron is wrapped around the front apron roller. This component is made of leather or high-performance synthetic rubber and presents a ring-shaped structure. It is an essential key component of the roving frame. The apron plays a crucial role in the roving frame. It closely cooperates with the roller and jointly undertakes the complex tasks of controlling the movement of fibers, realizing yarn drafting and twisting.

[0003] The roller, usually made of metal material, forms a complementary pair with the apron. However, during the actual operation process, due to the continuous contact and friction between the apron and the roller, the apron will gradually wear and become thinner. This wear not only changes the original shape of the apron but also has a profound impact on its cooperation relationship with the roller.

[0004] After the apron wears 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 field, making the movement state of the fibers during the drafting process become unstable, the force distribution of the fibers become uneven, and further affecting the evenness and strength of the yarn, greatly reducing the overall quality of the yarn.

[0005] Even more seriously, the wear and thinning of the apron also weaken its holding force on the fibers. The apron that originally tightly wrapped around the fibers can no longer provide sufficient support and holding due to wear, resulting in the fibers being more likely to slip or break during the drafting process. This situation not only exacerbates the unevenness of the yarn but also significantly increases the breakage rate, bringing many inconveniences and losses to production. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an improved front apron roller of a roving frame, which can automatically adjust the extrusion pressure between the apron and the roller when the extrusion pressure between the apron and the roller is less than a preset pressure value.

[0061] Please refer to Figures 1 to 10, An improved front apron roller of a roving frame, comprising a mounting frame 1 and a support plate 2. There are two groups of support plates 2, which are respectively arranged on the left and right sides of the mounting frame 1; a driving motor 6, which is installed on the upper surface of the support plate 2; an apron roller 7, which is installed on the output shaft of the driving motor 6; an apron 8, which is wrapped around the outer circumferential surface of the apron roller 7; a mounting plate 3, which is installed on the upper surface of the support plate 2, and the mounting plate 3 is close to the outer side surface of the mounting frame 1; a T-shaped chute 5, which is opened on the side surface of the support plate 2 and corresponds to the position of the mounting plate 3; a T-shaped slider 4, which is slidably arranged in the T-shaped chute 5, and one end of the T-shaped slider 4 is fixedly connected to the mounting plate 3; a first spring 15, which is fixedly installed on the lower end surface of the support plate 2; a detection plate 21, which is installed at the lower end of the first spring 15, and one end of the detection plate 21 is fixedly connected to the mounting frame 1; a control component, which is arranged on one side of the driving motor 6, and the control component is used to control the distance between the apron 8 and the roller 18. The control component includes a triangular block 14 and a rhombic column 12. The rhombic column 12 is used to squeeze the inclined surface of the triangular block 14 to control the downward movement of the apron 8; a detection component, which is installed on the apron roller 7, and the detection component includes a pressure sensor 19, which is used to detect the pressure received by the apron roller 7;

[0062] The control component further includes a baffle 9, which is fixedly installed on the upper end surface of the support plate 2 and is arranged at a position close to the side surface of the driving motor 6. The triangular block 14 is fixedly installed on the side surface of the baffle 9, and the triangular block 14 is installed on the side of the baffle 9 facing away from the driving motor 6. The rhombic column 12 is arranged on one side of the triangular block 14; a limiting column plate 11, which is sleeved on the side surface of the rhombic column 12, and one end of the limiting column plate 11 is fixedly connected to the mounting frame 1; a threaded column 13, which is arranged inside the rhombic column 12, and the threaded column 13 is threadedly connected to the inner wall of the rhombic column 12. One end of the threaded column 13 penetrates through the rhombic 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 further includes a pressing rod 16, which is arranged inside the apron roller 7 and one end extends out of the apron roller 7 to the outside. The pressing rod 16 at the outside is flush with the surface of the apron roller 7. The pressure sensor 19 is installed inside the apron roller 7 and the pressure sensor 19 is located at one end of the pressing rod 16; a conductive slip ring 17, which is installed at one end of the apron roller 7 away from the driving 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] According to the distance that the apron 8 moves down each time measured by the optoelectronic sensor 20, the processing unit records the distance that the apron 8 moves down each time. The processing unit also records the corresponding working duration when the apron 8 moves down each time. The remaining thickness of the apron 8 is calculated based on the initial thickness of the apron 8 and the distance that the apron 8 moves down each time;

[0068] Based on the recorded distance that the apron 8 moves down each time and the corresponding working duration, the wear amount of the apron 8 per unit time is calculated. Based on the wear amount of the apron 8 per unit time and the remaining thickness of the apron 8, the remaining service duration of the apron 8 is calculated.

[0069] By adopting the above technical solution, the thickness of the apron 8 is determined in advance. The optoelectronic sensor 20 measures the distance between the optoelectronic sensor 20 and the detection plate 21 in advance. The distance that the apron 8 moves down each time due to wear is the same as the distance that the optoelectronic sensor 20 moves down. The change amount of the distance between the optoelectronic sensor 20 and the detection plate 21 detected is the distance that the apron 8 moves down. By recording the distance that the apron 8 moves down each time through the processing unit, 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 down each time. Assuming the initial thickness of the apron 8 is , and the distance moved down each time is , where represents the number of times of moving down, and the remaining thickness of the apron 8 can be expressed as: , where represents the number of times of moving down.

[0070] The processing unit will record the corresponding working duration when the apron 8 moves down each time. Based on the recorded distance that the apron 8 moves down each time and the corresponding working duration, the wear amount of the apron 8 per unit time can be calculated. First, the total wear amount of the apron 8 is calculated as , , according to the total wear amount being and the total working duration of the apron 8 being , the average wear rate of the apron 8 can be calculated, , according to the average wear rate of the apron 8 and the remaining thickness of the apron 8, the time that the remaining thickness of the apron 8 can still be used can be calculated, , the obtained data information and the data information detected by the sensor can be transmitted to the operation panel of the roving frame through wire transmission, so that the staff can directly know the remaining service life of the apron 8, the current thickness and the remaining thickness of the apron 8 on the operation panel, etc., which is convenient for the staff to timely understand the current state of the apron 8. By real-time monitoring the wear condition of the apron 8, the wear problem can be found and processed in time, the downtime caused by the damage of the apron 8 can be reduced, and the equipment maintenance efficiency can be improved. By reasonably predicting the replacement time of the apron 8, the unnecessary replacement times of the apron 8 can be reduced, the production cost can be lowered, and the potential safety hazards such as the fracture of the apron 8 can be found in time by real-time monitoring the wear condition of the apron 8, so as to take corresponding measures to avoid the occurrence of safety accidents.

[0071] In some embodiments of the present invention, a rotating roller 23 is provided directly above the apron 8; a plurality of elastic hooks 24 are provided, and the plurality of elastic hooks 24 are evenly distributed on the side surface of the rotating roller 23;

[0072] A fixing plate 22 is installed on the upper end surface of the support plate 2; an installation cylinder 31 is rotatably installed on the support plate 2, and a rectangular groove is formed inside the installation cylinder 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 rotating roller 23.

[0073] By adopting the above technical solution, since the apron 8 is usually made of rubber or other synthetic materials, the apron 8 is subjected to large tension and pressure during use, which causes the fibrous material to be more easily compressed and adhered to the surface of the apron 8. When the fibrous material is adhered to the apron 8 in the present invention, the fibrous material will rotate along with the apron 8. As the fibrous material accumulates, the thickness of the apron 8 will increase. When the fibrous material moves to the upper end of the apron 8, it will contact the elastic hook 24, and the elastic hook 24 will hook the fibrous material on the apron 8, and at the same time drive the rotating roller 23 to rotate, so that the next set of elastic hooks 24 contacts the fibrous material on the apron 8, so that the fibrous material adhered to the apron 8 can be effectively removed, and the twisting effect of the apron 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 rotating roller 23, and the right end of the push rod 25 movably penetrates through the rotating roller 23 and extends to the outside; the number of cotton removal holes 26 corresponds to the number of elastic hooks 24, the cotton removal holes 26 are opened on the outer side surface of the rotating roller 23, and the shank of the elastic hook 24 passes through the cotton removal hole 26 and is fixedly connected to the push rod 25; a second spring 30 is fixedly connected to the left end of the push rod 25, and the second spring 30 is arranged inside the square rod 29; a push piece 27 is fixedly connected to the right end of the push rod 25; a finger sleeve 28 is fixedly connected to the right end of the rotating 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 cylinder 31. Then, the index finger and middle finger of the operator 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. The push rod 25 will move towards the inside of the square rod 29. When the push rod 25 moves, it will pull the hook handle of the elastic hook 24, causing the elastic hook 24 to move towards the cotton removal hole 26. The hook part of the elastic hook 24 is restricted by the cotton removal hole 26 and will change from the previous bent shape to a straight bar shape and enter the cotton removal 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 the cleaning is completed, the push piece 27 is released, and the second spring 30 resets and drives the push rod 25 to move in the reverse direction. At this time, the elastic hook 24 will protrude from the cotton removal hole 26. The elastic hook 24 is made of an elastic material and will return to its original state.

[0076] In some embodiments of the present invention, the square rod 29 is made of a ferromagnetic material, specifically iron and iron alloy materials, and the mounting cylinder 31 is made of a permanent magnetic material, cobalt, nickel or an alloy material of cobalt and nickel. This can make the square rod 29 magnetically attracted to the mounting cylinder 31, increasing the stability of the square rod 29 after installation and facilitating disassembly when cleaning the fiber cotton on the rotating roller 23.

[0077] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
