Description

Technical Field

[0001] The utility model relates to the technical field of unloading racks, in particular to a carbon fiber unloading rack. Background Art

[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It is the most resistant to high temperatures among all chemical fibers. It is made of acrylic and viscose fibers and is oxidized and carbonized at high temperatures. After processing, the carbon fiber line is usually wound on a yarn roller. When the carbon fiber line is needed to weave carbon fiber products, it is usually necessary to place multiple yarn rollers on a feed rack, on which a mounting shaft is provided. The yarn rollers are plugged into the mounting shaft. The current mounting shafts are all horizontally arranged on the feed rack, and then the yarn rollers are horizontally inserted into the mounting shaft. In this way, the gravity generated by the yarn rollers themselves is completely offset by the upward reaction force of the mounting shaft on the yarn rollers. When the yarn rollers rotate forward, due to the reaction force, a backward lateral friction resistance is generated between the yarn rollers and the mounting shaft. The friction resistance changes with the change of the weight of the yarn rollers themselves, and then the weight of the yarn rollers themselves affects the lateral tension of the yarns. In order to keep the lateral tension of the yarns unchanged, it is necessary to set an adjustment mechanism on the subsequent traction equipment, which greatly increases the manufacturing cost of the equipment. In view of this, overcoming the defects of the above-mentioned prior art is a problem to be solved in this technical field. Utility Model Content

[0003] In view of this, the utility model provides a carbon fiber unwinding rack, which aims to change the current horizontal arrangement of the yarn roller on the unwinding rack. The weight of the yarn roller itself affects the lateral tension of the yarn. In order to keep the lateral tension of the yarn unchanged, an adjustment mechanism needs to be set on the subsequent traction equipment, which greatly increases the manufacturing cost of the equipment.

[0004] To achieve the above purpose, the specific technical solution of a carbon fiber unwinding rack of the utility model is as follows:

[0005] The utility model provides a carbon fiber unwinding rack, comprising a supporting mechanism, wherein the supporting mechanism comprises a supporting frame, a mounting rod is fixed on the supporting frame, a mounting shaft is fixed on the mounting rod, a wire roller is rotatably mounted on the mounting shaft, an angle α is set between the axis of the mounting shaft and a perpendicular line in the vertical direction of the supporting frame, and the gravity G of the wire roller itself is offset by the reaction force F1 of the mounting rod to the wire roller and the reaction force F2 of the mounting shaft to the wire roller.

[0006] In one embodiment of the present invention, the angle α is 10-20°

[0007] In an embodiment of the present invention, an angle β is set between the installation rod and the horizontal line of the support frame.

[0008] In an embodiment of the present invention, the angle β is 10-30°.

[0009] In an embodiment of the present utility model, a connecting rib is fixed between the upper and lower mounting rods.

[0010] In one embodiment of the utility model, an angle adjustment mechanism is provided between the mounting rod and the support frame, and the angle adjustment mechanism can adjust the size of the angle α according to needs. The angle adjustment mechanism includes a rotating shaft, and the rotating shaft is fixedly installed at the two end portions of the mounting rod, and the rotating shaft is rotatably connected to the support frame. A knob is fixed to the end of one of the rotating shafts, and the knob is arranged on the outside of the support frame. Turning the knob drives the rotating shaft to rotate, and then the rotating shaft drives the mounting rod to rotate around the axis of the rotating shaft, so that the mounting rod drives the mounting shaft thereon to rotate around the axis of the rotating shaft, and then the size of the angle α between the axis of the mounting shaft and the vertical direction of the support frame changes.

[0011] In an embodiment of the utility model, a handle is fixed to one side of the knob, and a rubber sleeve is sleeved on the outer side of the handle.

[0012] In an embodiment of the utility model, an indicator line is provided on the end surface of the knob, and a scale line matching the indicator line is provided on the support frame, and the value of the current angle α can be indicated by the cooperation of the indicator line and the scale line.

[0013] In one embodiment of the utility model, a locking mechanism is provided between the rotating shaft and the support frame, and the locking mechanism can lock the rotating shaft. The locking mechanism includes a top shaft bolt, and the top shaft bolt is threadedly connected to the support frame, and the top shaft bolt can penetrate the support frame and come into contact with the outer cylindrical surface of the rotating shaft.

[0014] In an embodiment of the utility model, two groups of locking mechanisms are provided, and the two groups of locking mechanisms are respectively distributed at two rotating shaft positions at both ends of the mounting rod, and the two groups of locking mechanisms are symmetrically distributed on both sides of the rotating shaft.

[0015] The beneficial effects of the utility model are:

[0016] 1. Because the angle α is set between the axis of the installation shaft and the vertical line of the support frame, the gravity G of the wire roller itself is offset by the force F1 of the installation rod and the force F2 of the installation shaft. Since the value range of the angle α is 10-20°, the angle is small. According to the force analysis, F1 is much larger than F2. Therefore, the gravity G of the wire roller itself is basically offset by F1. The force direction of F1 is perpendicular to the forward lateral tension of the yarn. Therefore, F1 does not affect the forward lateral tension of the yarn. Therefore, the weight of the wire roller itself has little effect on the forward lateral tension of the yarn. Therefore, there is no need to add a device for adjusting the lateral tension of the yarn on the subsequent equipment, which greatly saves the equipment manufacturing cost.

[0017] 2. An angle β is set between the mounting rod and the horizontal line of the support frame, so the multiple wire rollers installed on the mounting rod are radially distributed outward along the direction of the yarn moving forward, and the yarn is pulled by the front traction device, so the yarn on each different wire roller has a certain distance in the horizontal direction, and will not contact each other and affect each other, avoiding the occurrence of yarn entanglement or contact friction between the yarns, so that each yarn is subjected to uniform force;

[0018] 3. An angle adjustment mechanism is provided between the mounting rod and the support frame. The number of wire rollers required varies according to different products, and the weight of the wire rollers also varies. In order to be able to adjust the size of the angle α at any time according to different situations, an angle adjustment mechanism is provided. The mounting rod is rotated by a knob, and the mounting rod can drive the wire roller thereon to rotate along the axis of the rotating shaft, thereby realizing the adjustment of the size of the angle α, improving the mobility and flexibility of the device, facilitating work, and greatly improving work efficiency;

[0019] 4. By setting a locking mechanism between the rotating shaft and the support frame, when the angle α is adjusted, the top shaft bolt is rotated to make it tightly contact with the rotating shafts at both ends of the mounting rod, so that the rotating shaft cannot rotate and is locked. Then the mounting rod is locked, and the size of the angle α cannot be changed, so the position of the alignment roller is locked, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example

[0040] At present, the mounting shaft is horizontally arranged on the unwinding frame, and then the yarn roller is horizontally inserted on the mounting shaft, so that the gravity generated by the yarn roller itself is completely offset by the upward reaction force F of the mounting shaft on the yarn roller (such as Figure 5 As shown in the figure, when the yarn roller rotates forward, due to the reaction force, a backward lateral friction resistance is generated between the yarn roller and the mounting shaft. The friction resistance changes with the weight of the yarn roller itself. Then the weight of the yarn roller itself affects the lateral tension of the yarn. In order to keep the lateral tension of the yarn unchanged, an adjustment mechanism needs to be set on the subsequent traction equipment, which greatly increases the manufacturing cost of the equipment. Therefore, it is urgent to solve the above problem.

[0041] See also Figure 1 and Figure 2In view of the above problems, the utility model provides a carbon fiber unwinding rack, including a support mechanism 100, the support mechanism 100 includes a support frame 110, the support frame 110 includes a plurality of horizontally and vertically arranged metal rods, the support frames 110 are welded to form the entire frame, a mounting rod 120 is fixed to the support frame 110 by welding, a plurality of mounting rods 120 can be arranged from top to bottom, and two rows of mounting rods 120 can also be arranged in the horizontal direction. Preferably, because the mounting rod 120 is long and the mounting rod 120 is subjected to a large pressure after the wire roller 140 is installed on the mounting rod 120, the middle position of the mounting rod 120 is easy to be concave or even broken, so between the upper and lower mounting rods 120, a connecting rib 121 (such as Figure 2 As shown), each row of mounting rods 120 is fixedly connected into one piece by connecting ribs 121, thereby improving the stability and firmness of the installation of the mounting rods 120.

[0042] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 Specifically, a mounting shaft 130 is fixed to the upper end surface of the mounting rod 120 by bolts, and the mounting shaft 130 is vertically arranged with the upper end surface of the mounting rod 120. A plurality of mounting shafts 130 are arranged equidistantly along the mounting rod 120 in the horizontal direction, and a wire roller 140 is inserted into each mounting shaft 130. The wire roller 140 is wound with carbon fiber yarn, and a gap is left between the wire roller 140 and the mounting shaft 130. The wire roller 140 can rotate on the mounting shaft 130, thereby realizing the wire release function, because the angle α (such as α) between the axis of the mounting shaft 130 and the vertical line of the support frame 110 in the vertical direction is set. Figure 4 As shown), the weight G of the wire roller itself is offset by the force F1 of the mounting rod acting on the wire roller and the force F2 of the mounting shaft acting on the wire roller (as shown). Figure 6 As shown in Figure 2), since the value range of the angle α is 10-20°, the angle is small. According to the force analysis, F1 is much larger than F2 (as shown in Figure 2). Figure 6 As shown in the figure, the gravity G of the wire roller itself is basically offset by F1, and the force direction of F1 is perpendicular to the forward lateral tension of the yarn, so F1 does not affect the forward lateral tension of the yarn. Therefore, the weight of the wire roller itself has little effect on the forward lateral tension of the yarn. Therefore, there is no need to add a device for adjusting the lateral tension of the yarn on the subsequent equipment, which greatly saves the equipment manufacturing cost.

[0043] See also Figure 7 , Figure 8 and Fig. 9It should be noted that an angle β is set between the installation rod 120 and the horizontal line of the support frame 110. The installation rods 120 are preferably arranged in two rows and stacked on the support frame 110. Therefore, the multiple wire rollers 140 installed on the installation rod 120 are radially distributed outward along the direction of the forward movement of the yarn. Under the pulling of the front traction device, the yarn moves forward, so the yarns on each different wire roller have a certain distance in the horizontal direction, and will not contact each other or affect each other, thereby avoiding the occurrence of entanglement between the yarns, or contact friction, etc., so that each yarn is subjected to uniform force. In order to make the space occupied by the entire support frame 110 not too large and to ensure that each yarn has a certain safety distance from each other, the angle β is 10-30°.

[0044] See also Fig.10 and Fig.11 The number of wire rollers 140 required for different products is different, and the weight of the wire rollers 140 is also different. In order to be able to adjust the size of the angle α at any time according to different situations, an angle adjustment mechanism 200 is provided between the mounting rod 120 and the support frame 110. The angle adjustment mechanism 200 can adjust the size of the angle α according to needs. Specifically, the angle adjustment mechanism 200 includes a rotating shaft 210. The rotating shaft 210 is fixedly installed at both ends of the mounting rod 120 by welding. The rotating shaft 210 is rotatably connected to the vertical support frames 110 at the front and rear ends of the mounting rod 120. The rotating shaft 210 penetrates the support frame 110. And extends to the outside, a knob 220 is fixed at the end of one of the rotating shafts 210, and the knob 220 is arranged on the outside of the support frame 110. Specifically, a handle 221 is fixed to one side of the knob 220 by welding, and the handle 221 is a metal rod with a first length. By utilizing the principle of leverage, a worker can quickly and labor-savingly turn the knob 220 by turning the handle 221, thereby driving the installation rod 120 to rotate. Preferably, a rubber sleeve 2211 is sleeved on the outside of the handle 221, so that when the worker turns the handle 221 by hand, the hand contacts the rubber sleeve 2211 to avoid slipping, making it convenient for the worker to apply force.

[0045] See also Fig.10 and Fig.11 When the angle α needs to be adjusted, the knob 220 is rotated by the handle 221, and the knob 220 drives the rotating shaft 210 to rotate, and the rotating shaft 210 drives the mounting rod 120 to rotate around the axis of the rotating shaft 210, so that the mounting rod 120 drives the mounting shaft 130 thereon to rotate around the axis of the rotating shaft 210, and the angle α between the axis of the mounting shaft 130 and the vertical direction of the support frame 110 changes.

[0046] See also Fig.10 and Fig.11It should be noted that an indicator line 222 is provided on the end face of the knob 220, and a scale line 111 matching the indicator line 222 is provided on the support frame 110. The scale line 111 is an angle line. The cooperation between the indicator line 222 and the scale line 111 can indicate the value of the current angle α. Workers can accurately and quickly adjust the verticality of the angle α according to the scale line, so that the adjustment accuracy is high, the work is convenient, and the work efficiency is greatly improved.

[0047] See also Fig.12 , Fig.13 and Fig.14 In addition, a locking mechanism 300 is provided between the rotating shaft 210 and the support frame 110. The locking mechanism 300 can lock the rotating shaft 210. The locking mechanism 300 includes a top shaft bolt 310. The top shaft bolt 310 is preferably a butterfly bolt. The top shaft bolt 310 is threadedly connected to the support frame 110, and the top shaft bolt 310 can penetrate the support frame 110 and contact the outer cylindrical surface of the rotating shaft 210. The locking mechanism 300 is provided with two groups. The two groups of locking mechanisms 300 are respectively distributed at the two rotating shaft 210 positions at both ends of the mounting rod 120, and the two groups of locking mechanisms 300 are symmetrically distributed on both sides of the rotating shaft 210.

[0048] See also Fig.14 By providing a locking mechanism 300 between the rotating shaft 210 and the support frame 110, when the angle α is adjusted, the top shaft bolt 310 is rotated to make it tightly contact with the rotating shaft 210 at both ends of the mounting rod 120, so that the rotating shaft 210 cannot rotate, and the mounting rod 120 is locked, and then the mounting shaft 130 is locked, and the size of the angle α cannot be changed, and the position of the alignment roller 140 is locked, which greatly improves the safety after the angle α is adjusted.
