Description

Technical Field

[0001] The utility model relates to textile equipment, in particular to a carbon fiber slitting device. Background Art

[0002] As the production efficiency of carbon fiber production equipment becomes higher and higher, the market has an overcapacity. The production cost of large-tow carbon fiber is low, and its price is getting closer to the cost. Small-tow carbon fiber is more difficult to produce, and its price is also higher. Therefore, slitting equipment has appeared to cut large-tow carbon fiber into small-tow carbon fiber. However, when the current slitting equipment cuts the carbon fiber, fuzzing will occur at the cutting point. Since the tension of the carbon fiber changes during the transportation process, the carbon fiber cannot be cut normally when the tension is small. Summary of the Invention

DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0040] First, combine Figures 1 to 8 A carbon fiber slitting device according to an embodiment of the present invention is described, which is used to slit a carbon fiber roll.

[0041] like Figures 1 to 6 As shown, a carbon fiber slitting device according to an embodiment of the present invention comprises: an unwinding assembly 1, a slitting assembly 2 and a winding assembly 3;

[0042] The unwinding assembly 1 is used to unwind the material to the slitting assembly 2;

[0043] The slitting assembly 2 includes: a sizing mechanism 5 and a slitting mechanism 6;

[0044] The sizing mechanism 5 is used to sizing a single side of the roll, and the slitting mechanism 6 is suitable for slitting the roll;

[0045] The slitting mechanism 6 includes a slitting plate 66, a slitting tool 67 and an elastic member 68;

[0046] The slitting plate 66 is provided with a groove for mounting a slitting tool 67. The slitting tool 67 is located in the groove. The slitting tool 67 has a center hole. A connecting hole is opened on the slitting plate 66 corresponding to the center hole. The elastic member 68 passes through the center hole and the connecting hole to elastically connect the slitting tool 67 to the slitting plate 66.

[0047] The winding assembly 3 is used to collect the material rolls that have passed through the slitting assembly 2 .

[0048] The unwinding component 1 provides the material roll to the slitting component 2, and the sizing mechanism 5 takes up the line to sizing one side of the material roll, effectively avoiding the problem of fuzzing of the material roll during slitting. The slitting tool 67 is connected to the slitting plate 66 through the elastic part 68, and the elastic part 68 enables the slitting tool 67 to always maintain the position of slitting the material roll, avoiding the problem of normal slitting due to low tension of the material roll.

[0049] like Figure 5~Figure 6 As shown, the sizing mechanism 5 includes: a slurry tank 51 and a feeding roller 52;

[0050] The slurry tank 51 contains slurry for sizing, and part of the loading roller 52 is located in the slurry tank 51. The upper part of the loading roller 52 contacts the lower surface of the material roll and is used to apply the slurry in the slurry tank 51 to the lower surface of the material roll.

[0051] The loading roller 52 rotates on the slurry tank 51, and can adhere the slurry in the slurry tank 51 to the surface of the loading roller 52. After the material roll passes over the top of the loading roller 52, the slurry on the loading roller 52 will adhere to the surface of the material roll. In this embodiment, the slurry is a sizing agent.

[0052] like Figure 6 As shown, the slitting mechanism 6 includes: a mounting plate 61, a guide post 62, a sliding block 63, a spring 64 and a fixing bolt 65;

[0053] A guide column 62 is provided on one side of the mounting plate 61, and the sliding block 63 is slidably set on the guide column 62. The two ends of the spring 64 are respectively connected to the mounting plate 61 and the sliding block 63. The cutting plate 66 is provided on the sliding block 63, and the fixing bolt 65 is used to connect the mounting plate 61 with the cutting plate 66.

[0054] The mounting plate 61 is fixed on the slitting frame 21, and the sliding block 63 is slidably set on the mounting plate 61 through the guide column 62. The spring 64 makes the sliding block 63 close to the mounting plate 61. The position of the sliding block 63 on the guide column 62 can be adjusted by the fixing bolt 65, and the sliding block 63 is fixed to the position where the material roll can be slit.

[0055] like Figure 5As shown, the slitting assembly 2 includes: a slitting frame 21, a tension adjustment mechanism 4, a yarn deviation correction adjustment mechanism 24, a drying mechanism 22 and a first traction mechanism 23;

[0056] The tension adjustment mechanism 4, the yarn deviation correction adjustment mechanism 24, the drying mechanism 22 and the first traction mechanism 23 are all arranged on the slitting frame 21. The tension adjustment mechanism 4 is used to adjust the tension of the material roll, the yarn deviation correction adjustment mechanism 24 is used to adjust the position of the material roll when it is transported to the slitting mechanism 6, the drying mechanism 22 is used to dry the material rack after slitting, and the first traction mechanism 23 is used to pull the dried material roll to the winding component 3.

[0057] When the tension of the material roll is low, the tension adjustment mechanism 4 can control the second traction mechanism 15 of the unwinding assembly 1 to stop for a certain period of time, thereby increasing the tension of the material roll. The yarn deviation correction adjustment mechanism 24 adjusts the position of the material roll when it is delivered to the slitting mechanism 6, ensuring that the material roll is in a suitable position for slitting each time it is delivered to the slitting mechanism 6. In this embodiment, the yarn deviation correction adjustment mechanism 24 consists of a motor, a material roll rod and two sensors. The two sensors are respectively arranged on both sides of the material roll. When the material roll triggers one of the sensors, the motor drives the material roll rod to move in the opposite direction. The material roll rod changes the position of the material roll through friction, so that the material roll is between the two sensors, ensuring that the material roll can be cut normally when it is delivered to the slitting mechanism 6.

[0058] like Figure 5 As shown, the tension adjustment mechanism 4 includes: a first roller 41, a second roller 42, an adjustment wheel 43, an adjustment rod 44 and a trigger 45;

[0059] The first roller 41 and the second roller 42 are arranged in parallel on the slitting frame 21, one end of the adjusting rod 44 is rotatably connected to the slitting frame 21, and the other end is connected to the adjusting wheel 43. The adjusting wheel 43 is suspended between the first roller 41 and the second roller 42 through the material roll. The trigger 45 is set on the slitting frame 21. When the tension of the material roll is low, the adjusting rod 44 can trigger the trigger 45. The trigger 45 is used to control the opening and closing of the unwinding assembly 1.

[0060] When the tension of the roll becomes low, the hanging height of the adjusting wheel 43 will become low, and the adjusting rod 44 will rotate downward, so that the adjusting rod 44 triggers the trigger 45. The trigger 45 can stop the second traction mechanism 15 of the unwinding assembly 1, so that the hanging height of the adjusting wheel 43 rises, thereby increasing the tension of the roll. When the tension of the roll changes, the position of the adjusting wheel 43 changes, so that the tension of the roll will not be too low, thereby ensuring that the tension of the roll remains within a range suitable for slitting.

[0061] like Figures 2 to 4 As shown, the unwinding assembly 1 includes: a material unwinding mechanism and a second traction mechanism 15;

[0062] The unwinding mechanism is used to provide the material roll to the second traction mechanism 15 . The unwinding mechanism can keep the unwinding direction of the material roll unchanged. The second traction mechanism 15 is used to pull the material roll to the slitting assembly 2 .

[0063] The unloading mechanism includes: an unloading roller 11, a linear mechanism 12, an unloading sensor 13 and a pressure sensor 14;

[0064] The unloading roller 11 is used to provide the material roll, the unloading sensor 13 is used to detect the direction of the unloading roller 11, the linear mechanism 12 moves the unloading roller 11 according to the detection of the unloading sensor 13, and the pressure sensor 14 is used to detect the tension of the material roll and control the unloading speed of the unloading roller 11 according to the detection result.

[0065] The unwinding roller 11 is driven by a motor to unwind the material. The material roll first passes through the unwinding sensor 13, which detects the position of the material roll being unwound by the unwinding roller 11. The linear mechanism 12 moves the unwinding roller 11 based on the detection result of the unwinding sensor 13, keeping the position of the material roll unchanged. The material roll then passes under the pressure sensor 14. The pressure sensor 14 detects the pulling force of the material roll on the pressure sensor 14, thereby detecting the tension of the material roll. The pressure sensor 14 controls the unwinding speed of the unwinding roller 11 based on the detected force. In this embodiment, the linear mechanism 12 is a linear module. The pressure sensor 14 is rotatably connected to the frame supporting the unwinding assembly 1 via a connecting rod, so that the pressure sensor 14 changes position according to the tension of the material roll, maintaining the tension of the material roll balanced.

[0066] like Figures 2 to 4 As shown, the discharge sensor 13 includes: a detection rod, a first sensor and a second sensor;

[0067] The first sensor and the second sensor are arranged on the detection rod, and the material roll passes between the first sensor and the second sensor. When the first sensor and the second sensor detect the material roll, they control the linear mechanism 12 to move the unwinding roller 11.

[0068] The material roll passes between the first sensor and the second sensor. When the material roll triggers the first sensor or the second sensor during the conveying process, the first sensor or the second sensor will control the linear mechanism 12 to move in the opposite direction to ensure that the material roll is between the first sensor and the second sensor.

[0069] like Figures 2 to 4 As shown, the winding assembly 3 includes: a winding frame 31, a tension roller 32, a rotating rod 33, a detection roller 34, a pressure detector 35, a winding wheel 36, a winding linear mechanism 37 and a winding detector;

[0070] One end of the rotating rod 33 is rotatably connected to the winding frame 31 and the other end is connected to the tension roller 32. The material roll passes around from the bottom of the tension roller 32 and then passes around from the top of the detection roller 34. Pressure detectors 35 are provided below both ends of the detection roller 34. The pressure detectors 35 are fixed on the winding frame 31. The pressure detectors 35 can close the slitting assembly 2.

[0071] The winding linear mechanism 37 is arranged on the winding frame 31, the winding wheel 36 is arranged at the output end of the winding linear mechanism 37, the winding detector is arranged on the winding frame 31, and is used to detect the material roll conveying position. The winding linear mechanism 37 is used to move the winding wheel 36 according to the detection result of the winding detector.

[0072] The material roll passes around the bottom of the tension roller 32, then passes around the top of the detection roller 34, and is finally collected by the winding wheel 36. The tension roller 32 can be rotated by the rotating rod 33 to adjust the position of the tension roller 32. When the tension of the material roll becomes low, the tension roller 32 rotates downward to keep the tension of the material roll balanced. The material roll exerts a certain pressure on the detection roller 34. When the detection result of the pressure detector 35 becomes low to a certain extent, the pressure detector 35 will control the first traction mechanism 23 to stop, so that the tension of the material roll increases, and the tension roller 32 rotates upward.

[0073] The winding detector can detect the position of the roll, and the winding linear mechanism 37 can adjust the position of the winding wheel 36 according to the detection result of the winding detector so that the winding wheel 36 can keep collecting the roll. In this embodiment, the winding linear mechanism 37 is a linear module.

[0074] In this application, the material rolls after slitting by the slitting component 2 can be collected through the carbon fiber widening yarn winding drum. When the slitting component 2 stops working, the material rolls are large tow carbon fibers, and the material rolls can be wound through a conventional winding machine.

[0075] Above, refer to Figures 1 to 8 A carbon fiber slitting device according to an embodiment of the present invention is described. The unwinding component 1 provides a material roll to the slitting component 2, and the sizing mechanism 5 takes up the line to sizing a single side of the material roll, effectively avoiding the problem of fuzzing of the material roll during slitting. The slitting tool 67 is connected to the slitting plate 66 through an elastic member 68. The elastic member 68 enables the slitting tool 67 to always maintain the position of slitting the material roll, avoiding the problem of normal slitting due to low tension of the material roll.
