DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example: Reference Figure 1-Figure 7 A tension-adjustable yarn rack comprises: a base 1, a yarn roller group 2, a yarn passing roller 3, an intermediate yarn passing roller group 4 and a tension adjustment mechanism 5. The yarn roller group 2 is installed on the base 1, and multiple yarn passing rollers 3 are provided parallel to one side of the yarn roller group 2. The yarn passing roller 3 is connected to the base 1 through the tension adjustment mechanism 5. The base 1 is equipped with an intermediate yarn passing roller group 4, and the intermediate yarn passing roller group 4 is arranged below the yarn passing roller 3.

[0028] The principles and beneficial effects of the above scheme are:

[0029] The operator winds the carbon cloth on the yarn roller group 2, pulls the end of the carbon cloth through the middle yarn roller group 4 and multiple yarn rollers 3 in turn, and places the end of the carbon cloth in the loom, and adjusts the tension adjustment mechanism 5 to control the overall tension of the carbon cloth. By setting the tension adjustment mechanism 5, the overall tension of the carbon cloth can be adjusted according to actual conditions. While placing the yarn rack to transport the carbon cloth, the tension of the carbon cloth can be accurately controlled to improve the protection of the carbon cloth and prevent the carbon cloth from being torn or loose.

[0030] The tension adjustment mechanism 5 includes: a vertical plate 6, a seat bearing 8, a return spring 9 and a locking bolt 10. A vertical plate 6 is installed on each side of the base 1. The end faces of the two vertical plates 6 are provided with longitudinal sliding grooves. The seat bearing 8 is slidably connected in the longitudinal sliding grooves. The bottom surface of one end of the seat bearing 8 is connected to the bottom wall of the longitudinal sliding groove through the return spring 9. The end of the yarn roller 3 is rotatably connected to the seat bearing 8. The other end of the seat bearing 8 is threadedly connected to the locking bolt 10. The bottom end of the locking bolt 10 is frictionally engaged with the side wall of the yarn roller 3.

[0031] The principles and beneficial effects of the above scheme are:

[0032] When the fiber strength of the carbon cloth is small and the required tension is small, the locking bolt 10 is turned left to disengage the end of the locking bolt 10 from the contact with the side wall of the yarn roller 3. When the loom is weaving, the carbon cloth is transported into the loom. The transportation of the carbon cloth drives the yarn roller 3 to move downward a small distance. The movement of the yarn roller 3 drives the seat bearing 8 to move downward. The seat bearing 8 compresses the return spring 9. The distance the return spring 9 is compressed is short, and the range of change of the carbon cloth tension is small.

[0033] When the fiber strength of the carbon cloth is high and the required tension is large, the locking bolt 10 is turned to the right to make the end of the locking bolt 10 rub against the side wall of the yarn roller 3. When the loom is weaving, the carbon cloth is transported into the loom. The transportation of the carbon cloth drives the yarn roller 3 to move downward a large distance. The movement of the yarn roller 3 drives the seat bearing 8 to move downward. The seat bearing 8 compresses the reset spring 9. The reset spring 9 is compressed over a long distance, and the range of change of the carbon cloth tension is large. By setting the tension adjustment mechanism 5, the tension can be preset according to actual conditions, which improves the stability of the carbon cloth during transportation, prevents the carbon cloth from being torn, and prevents the carbon cloth from being loose. A longitudinal slide groove is provided on the vertical plate 6, and the bottom wall of the longitudinal slide groove is connected to the seat bearing 8 through the reset spring 9, which makes full use of the space in the device.

[0034] The intermediate yarn passing roller group 4 includes: a second vertical plate 11, an intermediate yarn passing roller 12 and a second seat bearing 13. A second vertical plate 11 is installed on each side of the base 1. The second vertical plate 11 is arranged between the two vertical plates 6. A second longitudinal slide groove is opened on the second vertical plate 11. A second seat bearing 13 is slidably connected in the second longitudinal slide groove. The bottom surface of the second seat bearing 13 is connected to the bottom wall of the second longitudinal slide groove through a yarn passing return spring. The end of the intermediate yarn passing roller 12 is rotatably connected to the second seat bearing 13, and the intermediate yarn passing roller 12 is arranged below the yarn passing roller 3.

[0035] The principles and beneficial effects of the above scheme are:

[0036] After the preset tension adjustment of the device is completed, the carbon cloth is conveyed by the power of the loom. When the carbon cloth is being conveyed, the carbon cloth and the middle yarn roller 12 are frictionally matched. When the carbon cloth is pulled, the middle yarn roller 12 moves upward while rotating. The upward movement of the middle yarn roller 12 drives the second belt seat bearing 13 to move upward. The yarn return spring is pulled upward by the second belt seat bearing 13 to prevent the carbon cloth from being torn.

[0037] When the carbon cloth is pulled to stop, the yarn returning spring is reset, and the yarn returning spring resets to drive the second belt seat bearing 13 to move downward, and the second belt seat bearing 13 moves downward to drive the middle yarn passing roller 12 to move downward, and the middle yarn passing roller 12 moves downward to apply tension to the carbon cloth to prevent the carbon cloth from loosening. By setting the middle yarn passing roller group 4, the control effect of the device on the tension applied to the carbon cloth is improved; at the same time, the buffering effect of the device on the tension applied to the carbon cloth is improved. The middle yarn passing roller group 4 cooperates with the yarn passing roller 3 and the tension adjustment mechanism 5 to further improve the device's ability to control the tension applied to the carbon cloth.

[0038] The yarn roller group 2 includes: a yarn roller 14, a mounting plate 15, a guide wheel 16 and an upper guide mechanism 17. A mounting plate 15 is installed on each side of the base 1. Two guide wheels 16 are rotatably connected to the mounting plate 15. The top walls of the two guide wheels 16 are frictionally engaged with the side walls of one end of the yarn roller 14. An upper guide mechanism 17 is installed on the base 1. The upper guide mechanism 17 is adjacent to the mounting plate 15. The bottom end of the upper guide mechanism 17 is frictionally engaged with the side wall of one end of the yarn roller 14.

[0039] The principles and beneficial effects of the above scheme are:

[0040] When the loom is weaving the carbon cloth, the end of the carbon cloth moves into the loom, and the movement of the carbon cloth drives the rotation of the yarn roller 14, and the rotation of the yarn roller 14 drives the two guide wheels 16 that are frictionally engaged with it to rotate, and the guide mechanism 17 is frictionally engaged with the yarn roller 14; by setting two guide wheels 16, each guide wheel 16 is frictionally engaged with the side wall of one end of the yarn roller 14, thereby improving the rotation effect of the yarn roller 14; at the same time, reducing the heat generated by the yarn roller 14 during rotation; by having two guide wheels 16 rotatably connected to the mounting plate 15, the stability of the installation of the guide wheel 16 is improved, and the guide wheel 16 is prevented from being offset and causing the yarn roller 14 to wear.

[0041] The upper guide mechanism 17 includes: an L-shaped plate 18, a lifting mechanism 19 and an upper guide wheel 20. An L-shaped plate 18 is installed on each side of the base 1. The L-shaped plate 18 is arranged parallel to the side wall of the mounting plate 15. The L-shaped plate 18 is equipped with a lifting mechanism 19. The bottom end of the lifting mechanism 19 is rotatably connected to two upper guide wheels 20. The bottom wall of the upper guide wheel 20 is frictionally engaged with the side wall of one end of the yarn roller 14.

[0042] The principles and beneficial effects of the above scheme are:

[0043] By installing a lifting mechanism 19 on the L-shaped plate 18, two upper guide wheels 20 are installed on the lifting mechanism 19. Each upper guide wheel 20 is frictionally engaged with the side wall of one end of the yarn roller 14. The upper guide wheel 20 and the guide wheel 16 cooperate with each other, which improves the rotation efficiency of the yarn roller 14 and also improves the stability of the yarn roller 14 during rotation.

[0044] The lifting mechanism 19 includes: a second L-shaped plate 21, a guide column 22 and a lifting bolt 23. The lifting screw hole of the L-shaped plate 18 is threadedly connected to the lifting bolt 23. The bottom side wall of the lifting bolt 23 is provided with an annular groove. The side wall of the second L-shaped plate 21 is provided with a second mounting groove. The annular groove is slidably connected to the second mounting groove. The guide column 22 on the top surface of the second L-shaped plate 21 is slidably connected to the guide hole on the top surface of the L-shaped plate 18. Two upper guide wheels 20 are rotatably connected to the second L-shaped plate 21.

[0045] The principles and beneficial effects of the above scheme are:

[0046] When the yarn roller 14 needs to be installed or replaced, the lifting bolt 23 is turned leftward, and the lifting bolt 23 moves upward relative to the L-shaped plate 18, and at the same time drives the second L-shaped plate 21 connected thereto to move upward, and the second L-shaped plate 21 drives the upper guide wheel 20 to move upward, and the guide column 22 on the second L-shaped plate 21 is slidably connected to the guide hole on the top surface of the L-shaped plate 18, and the guide column 22 moves upward guided by the guide hole;

[0047] After the yarn roller 14 is placed, the lifting bolt 23 is rotated to the right. The lifting bolt 23 moves downward relative to the L-shaped plate 18, and at the same time drives the second L-shaped plate 21 connected thereto to move downward. The second L-shaped plate 21 drives the upper guide wheel 20 to move downward. The guide column 22 moves downward through the guide hole until the side wall of the upper guide wheel 20 contacts the side wall of the yarn roller 14. The rightward rotation of the lifting bolt 23 is stopped.

[0048] By providing an annular groove on the side wall of the lifting bolt 23, the annular groove is slidably connected to the second mounting groove. When the lifting bolt 23 moves upward or downward relative to the L-shaped plate 18, the second L-shaped plate 21 can be driven to move, thereby improving the lifting efficiency of the mechanism;

[0049] By providing a guide post 22 on the top surface of the second L-shaped plate 21, the guide post 22 is slidably connected with the guide hole on the top surface of the L-shaped plate 18, thereby improving the accuracy of the lifting and lowering of the mechanism;

[0050] Two upper guide wheels 20 are rotatably connected to the second L-shaped plate 21. The upper guide wheels 20 are frictionally engaged with the yarn roller 14, thereby improving the stability of the yarn roller 14 during rotation and preventing the yarn roller 14 from escaping from the device.

[0051] A hand wheel 24 is installed on the top of the lifting bolt 23 .

[0052] The principles and beneficial effects of the above scheme are:

[0053] The lifting bolt 23 is driven to rotate by rotating the hand wheel 24 , which improves the convenience for the operator to screw the lifting bolt 23 . Since the diameter of the hand wheel 24 is larger than the diameter of the lifting bolt 23 , the efficiency of the rotation of the lifting bolt 23 is improved.

[0054] A third L-shaped plate 25 is installed on each side wall of the base 1. The inner wall of the third L-shaped plate 25 is frictionally matched with the end wall of the yarn roller 14. The top of the third L-shaped plate 25 is connected to a guide plate 26, and the top of the guide plate 26 is set away from the end of the yarn roller 14.

[0055] The principles and beneficial effects of the above scheme are:

[0056] When the yarn roller 14 needs to be installed, the second L-shaped plate 21 is moved upward to reserve space for the installation of the yarn roller 14. After the end of the yarn roller 14 is moved to the inner wall of the third L-shaped plate 25, the end of the yarn roller 14 can be accurately placed on the two guide wheels 16 through the guidance of the guide plate 26, and the end wall of the yarn roller 14 is frictionally matched with the inner wall of the third L-shaped plate 25, which reduces the difficulty of installing the yarn roller 14.

[0057] The inner wall of the third L-shaped plate 25 is provided with a circular groove, and the bottom end of the circular groove is connected to a second circular groove. The inner diameter of the second circular groove is larger than the inner diameter of the circular groove. A turntable 27 is rotatably connected in the circular groove. The end face of the turntable 27 is frictionally matched with the end wall of the yarn roller 14. The other end face of the turntable 27 is connected to a power disk 28. The power disk 28 is placed in the second circular groove. The side wall of the power disk 28 is equipped with multiple blades 29. The bottom end of the second circular groove is connected to one end of the drainage hole, and the top end of the second circular groove is connected to one end of the liquid inlet hole. The other ends of the drainage hole and the liquid inlet hole are both provided on the inner wall of the third L-shaped plate 25. The drainage hole and the liquid inlet hole are respectively plugged into and matched with the two ends of the coil 30. The coil 30 is connected to the bottom wall of the L-shaped plate 18 through multiple fins 31.

[0058] The principles and beneficial effects of the above scheme are:

[0059] When the end wall of the yarn roller 14 contacts the turntable 27, the rotation of the yarn roller 14 drives the turntable 27 that is frictionally engaged with it to rotate, and the rotation of the turntable 27 drives the power disk 28 to rotate. The power disk 28 drives the paddle 29 on its side wall to rotate in the second circular groove. The second circular groove and the coil 30 are filled with lubricating oil. Through the rotation of the paddle 29, the lubricating oil can be sucked from the liquid inlet hole and discharged from the liquid inlet hole into the coil 30. Since the second circular groove and the coil 30 are filled with lubricating oil, the lubricating oil can provide lubrication for the turntable 27 when it rotates.

[0060] At the same time, since the turntable 27 rotates at a high speed, the temperature of the lubricating oil rises quickly, and the lubricating oil can be driven by the blades 29 to flow and cooled by the coil 30, thereby increasing the service life of the lubricating oil;

[0061] The inner walls of the two third L-shaped plates 25 cooperate with each other, and the turntable 27 of the third L-shaped plate 25 positions the yarn roller 14 in the longitudinal direction to prevent the yarn roller 14 from moving during rotation, thereby further improving the stability of the yarn roller 14 after installation;

[0062] At the same time, by setting the turntable 27 in contact with the end wall of the yarn roller 14, the wear of the third L-shaped plate 25 itself is reduced, and the service life of the third L-shaped plate 25 is increased;

[0063] Since lubricating oil is injected into the second circular groove, the power disk 28 connected to the turntable 27 rotates in cooperation with the second circular groove, and the lubricating oil covers the power disk 28 in the second circular groove, when the yarn roller 14 rotates, while cooperating with the guide wheel 16 and the upper guide wheel 20 to fix the yarn roller 14, the lubricating oil can absorb and buffer the force of the end of the yarn roller 14 in all directions in space, thereby preventing the vibration of the yarn roller 14 or the end of the yarn roller 14 from being transmitted to the third L-shaped plate 25;

[0064] By setting a turntable 27 that is rotatably connected to the circular groove, one side of the turntable 27 contacts and cooperates with the end wall of the yarn roller 14. The turntable 27 can guide the rotating yarn roller 14 in a circumferential direction and can replace ordinary bearings. When disassembling and assembling the yarn roller 14, the assembly efficiency between the mechanisms is improved.

[0065] The side wall of the yarn roller 14 is provided with a plurality of heat dissipation plates 32 . The heat dissipation plates 32 are located between the mounting plate 15 and the L-shaped plate 18 . The heat dissipation plates 32 are arranged perpendicular to the fins 31 .

[0066] The principles and beneficial effects of the above scheme are:

[0067] When the yarn roller 14 is rotating, the yarn roller 14, the guide wheel 16 and the upper guide wheel 20 are in friction with each other to generate heat. The yarn roller 14 can be cooled by arranging a heat sink 32 on the yarn roller 14. After the rotating heat sink 32 comes into contact with the air, the heat dissipation efficiency of the yarn roller 14 is further increased, and the yarn roller 14 is prevented from being deformed due to heat after working for a long time. The flatness of the carbon cloth can be always maintained, and the tension of the carbon cloth is prevented from changing when the loom pulls the end of the carbon cloth, thereby preventing the carbon cloth from being torn or loosened.

[0068] It also includes: a filter device 33; the filter device 33 includes: a filter screen 34, a sealing disk 35, a second return spring 36, a power piece 37, a cleaning plate 38, a baffle 39 and a second filter screen 40, the liquid inlet is equipped with a filter screen 34, the two inner walls of the liquid inlet are respectively provided with a mounting groove and a collection groove, the mounting groove is connected to the mounting cavity, a sealing disk 35 is slidably connected in the mounting cavity, the side wall of the sealing disk 35 is connected to the second return spring 36, the second return spring 36 is connected to the inner wall of the mounting cavity, the inner wall of the mounting cavity is connected to the power piece 37, and the other side wall of the sealing disk 35 is connected to On one side of the cleaning plate 38, a plurality of through holes are opened on the cleaning plate 38, and the cleaning plate 38 slides with the mounting groove and the filter screen 34 respectively. The bottom end of the other side of the cleaning plate 38 is provided with a chamfer, and a second mounting groove is opened on the inner wall of the collecting groove. A baffle 39 is slidably connected in the second mounting groove. The top side wall of the baffle 39 is provided with a second chamfer, and the second chamfer is set toward the chamfer. The bottom end of the baffle 39 is connected to the bottom wall of the second mounting groove through a third return spring. The bottom end of the collecting groove is connected to one end of the balancing hole, and the other end of the balancing hole is opened on the inner wall of the liquid inlet hole. A second filter screen 40 is installed in the balancing hole.

[0069] One end of the fluid replenishing hole is formed in the balancing hole, and the other end of the fluid replenishing hole is formed on the third L-shaped plate 25. The fluid replenishing hole is equipped with a one-way valve.

[0070] The principles and beneficial effects of the above scheme are:

[0071] When the lubricating oil in the liquid inlet hole flows, the filter 34 filters the impurities in the lubricating oil. When the amount of impurities filtered on the filter 34 is large, the pressure in the liquid inlet hole above the top of the filter 34 increases, the power piece 37 is started, and the power piece 37 drives the sealing disk 35 to drive the cleaning plate 38 to move toward the baffle 39. The second return spring 36 is stretched, and the side wall of the cleaning plate 38 contacts the filter 34 to clean the impurities on the filter 34. The chamfer on the cleaning plate 38 pushes the impurities toward the baffle 39. When the chamfer contacts the second chamfer of the baffle 39, the impurities are removed. The baffle 39 is pushed into the second mounting groove, the third return spring is compressed, and the cleaning plate 38 continues to move into the collection groove, bringing impurities into the collection groove. Since the cleaning plate 38 has multiple through holes, the cleaned filter 34 cooperates with the through holes on the cleaning plate 38 to connect the liquid inlet. When the pressure in the liquid inlet above the top of the filter 34 decreases, the power member 37 is reset, and the reset of the second return spring 36 drives the reset of the sealing disk 35. After the baffle 39 is out of contact with the cleaning plate 38, it is reset under the action of the elastic force of the third return spring.

[0072] The bottom of the collecting tank is connected to one end of the balancing hole, and the other end of the balancing hole is opened on the inner wall of the liquid inlet hole. A second filter 40 is installed in the balancing hole. When impurities are replaced by the cleaning plate 38 into the collecting tank, the second filter 40 intercepts the impurities in the balancing hole to prevent the impurities from entering the liquid inlet hole again. The synchronous baffle 39 intercepts the impurities, further improving the collection effect of the mechanism on impurities.

[0073] By providing a balancing hole, a second filter 40 is installed in the balancing hole, and the balancing hole can store impurities and part of the lubricating oil at the same time. When the lubricating oil in the device is reduced, the stored lubricating oil can be discharged into the liquid inlet hole due to the negative pressure of the liquid inlet hole.

[0074] Since the filter device 33 works under sealed conditions, the second filter screen 40 is installed in the balancing hole to prevent excessive lubricating oil and impurities collected in the balancing hole, which may result in the impurities being unable to be continuously collected;

[0075] The cleaning plate 38 is slidably connected to the filter screen 34. The end of the cleaning plate 38 is chamfered. When the cleaning plate 38 moves toward the collecting tank, the chamfer forms an angle between the end of the cleaning plate 38 and the filter screen 34. While collecting impurities, the chamfer prevents the impurities from diffusing during movement.

[0076] Since the end of the baffle 39 is provided with a second chamfer, which is parallel to the chamfer, when the chamfer of the end of the cleaning plate 38 contacts the second chamfer of the end of the baffle 39, the baffle 39 can be quickly opened. At the same time, when the cleaning plate 38 is separated from the collection tank, the end of the baffle 39 with the second chamfer can clean the cleaning plate 38, further improving the collection effect of the mechanism on impurities.

[0077] When it is necessary to clean the impurities in the balancing hole or the collecting tank, the one-way valve and the coil can be removed, and cleaning liquid can be injected into the liquid inlet hole. The cleaning liquid enters the balancing hole and the collecting tank through the second filter 40. The impurities and part of the cleaning liquid are discharged through the liquid replenishment hole, and the other part of the cleaning liquid is discharged through the drainage hole, reducing the difficulty of cleaning the mechanism.

[0078] The power part 37 includes: a mounting ring 41 and a pressure plate 42. One end of the power hole is opened on the inner wall of the liquid inlet hole, and the other end of the power hole is connected to the mounting cavity. The mounting ring 41 is installed in the power hole. The mounting ring 41 is connected to the side wall of the pressure plate 42 through a fourth return spring. The pressure plate 42 and the power hole are slidably sealed.

[0079] The principles and beneficial effects of the above scheme are:

[0080] Gas or lubricating oil is filled between the pressure plate 42 and the sealing plate 35. When the filter 34 is clogged, the pressure on one side of the pressure plate 42 increases due to the pressure in the liquid inlet pipe, causing the pressure plate 42 to move toward the inside of the power hole. The fourth return spring is compressed, and at the same time, the pressure plate 42 applies pressure to the gas or lubricating oil, causing the sealing plate 35 to move toward the filter 34 to remove impurities. After the impurities on the filter 34 are removed, the pressure in the liquid inlet pipe returns to normal, and the pressure plate 42 is reset under the elastic force of the fourth return spring. The pressure applied to the gas or lubricating oil decreases, causing the sealing plate 35 to reset.

[0081] By providing the pressure plate 42, the mechanism can be operated according to the actual pressure conditions in the device, driving the sealing plate 35 to work or reset it, thereby improving the efficiency of the automatic operation of the device.

[0082] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
