Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber cloth processing, in particular to carbon fiber cloth processing equipment based on positioning cutting. Background Art

[0002] Carbon fiber cloth processing equipment based on positioning cutting is usually a CNC cutting machine, which can accurately position and cut on the cloth through pre-programmed programs to achieve high-precision and high-efficiency carbon fiber cloth processing.

[0003] There are many existing technologies for cutting carbon fiber cloth, such as:

[0004] Chinese patent publication number CN117418386A discloses a rotating carbon fiber cloth cutting device to avoid uneven cuts, including a fixing device and a control device arranged on the top of the fixing device, the fixing device is used to fix the positions of the carbon fiber cloth and the control device, and the control device includes a cutting mechanism. When the present invention cuts the carbon fiber cloth, two leveling frames press and fix the carbon fiber cloth at the cutting position, and in the cutting process, in order to avoid the carbon fiber cloth from wrinkling when cutting, when the cutting knife moves downward to cut the carbon fiber cloth, the leveling frame rotates to smooth the carbon fiber cloth to ensure that the cut of the carbon fiber cloth is neat, and when the cutting knife moves upward, the leveling frame presses the carbon fiber cloth down to avoid the problem of uneven cut position caused by the cutting position of the carbon fiber cloth being tilted, and the cut is smoother than the common vibration knife cutting method.

[0005] Therefore, it can be known that most carbon fiber cloth cutting devices use a cutting knife to cut the carbon fiber cloth. In order to facilitate cutting, a fixing device is usually used to fix the two sides of the carbon fiber cloth, and then the carbon fiber cloth is cut by the cutting knife. However, when the fixing device only fixes the two sides of the carbon fiber cloth without tensioning it, the carbon fiber cloth itself is in a relaxed state. At this time, the carbon fiber cloth is cut by a cutting knife. During the cutting process, the vibration of the cutting knife on the carbon fiber cloth will cause the carbon fiber cloth, which is in a relaxed state, to slide slightly during cutting, thereby causing the cut of the carbon fiber cloth to be uneven.

[0006] In view of this, the present invention provides a carbon fiber cloth processing device based on positioning cutting. Summary of the invention

At the same time, when the rotating frame is pressed to rotate horizontally and move to one side, the movable shell of the stabilizing rod contacts the carbon fiber cloth and is forced to slide, driving the friction block fixed on one side of the grabbing rod to be exposed from the through groove of the movable shell, thereby increasing the friction force of the stabilizing rod on the carbon fiber cloth and avoiding the situation that the pressure of the rotating frame on the carbon fiber cloth is insufficient to fix the carbon fiber cloth due to the smooth surface of the carbon fiber cloth.

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] Most carbon fiber cloth cutting devices use a cutting knife to cut the carbon fiber cloth. In order to facilitate cutting, a fixing device is usually used to fix the two sides of the carbon fiber cloth, and then the carbon fiber cloth is cut by the cutting knife. However, when the fixing device only fixes the two sides of the carbon fiber cloth without tensioning it, the carbon fiber cloth itself is in a relaxed state. At this time, the carbon fiber cloth is cut by the cutting knife. During the cutting process, the vibration of the cutting knife on the carbon fiber cloth will cause the carbon fiber cloth, which is in a relaxed state, to slide slightly during cutting, thereby causing the cut of the carbon fiber cloth to be uneven.

[0042] See also Figure 1-Figure 10As shown, the purpose of this embodiment is to provide a carbon fiber cloth processing equipment based on positioning cutting, including a workbench 100, the workbench 100 includes two symmetrically arranged machine bases 101, a conveying group 102 for conveying the carbon fiber cloth is provided between the two machine bases 101, a fixed cutting group 200 is provided above the conveying group 102, the fixed cutting group 200 is used to fix the position to be cut of the carbon fiber cloth above the conveying group 102, and further tension it after fixing, and the fixed cutting group 200 cuts the carbon fiber cloth transversely after fixing and tensioning the carbon fiber cloth.

[0043] The fixed cutting group 200 includes a cross column 210 and a connecting rod group 220. The two ends of the cross column 210 are fixedly connected to the two machine bases 101 respectively. The connecting rod group 220 is located between the two machine bases 101 and between the cross column 210 and the transmission group 102. The lower end of the connecting rod group 220 is in contact with the surface of the transmission group 102 and guides the forward direction of the carbon fiber cloth on the transmission group 102. A driving group 230 is connected between the two ends of the cross column 210 and the connecting rod group 220. The driving group 230 is used to drive the connecting rod group 220 to move up and down. The carbon fiber cloth can be fixed in the first step by moving the connecting rod group 220 downward. The carbon fiber cloth can be tensioned in the second step by driving the connecting rod group 220 to continue to move downward by the driving group 230.

[0044] The fixed cutting group 200 further includes a cutting member 240 . The cutting member 240 is located between the two driving groups 230 and moves horizontally. The carbon fiber cloth is cut during the horizontal movement of the cutting member 240 .

[0045] When the driving group 230 drives the connecting rod group 220 to move up and down, the connecting rod group 220 descends and moves to both sides, and fixes and tensions the carbon fiber cloth in the connecting rod group 220 to avoid uneven cuts on the carbon fiber cloth when the carbon fiber cloth is cut.

[0046] Depend on Figure 5-Figure 7 As shown, considering that the carbon fiber cloth is fixed while the portion to be cut is tensioned, thereby reducing the stretching and deformation of the carbon fiber cloth during the cutting process, the connecting rod group 220 includes a main rod 221 and a rotating frame 224. The lower end of the main rod 221 is rotatably connected to the center of the rotating frame 224. A stabilizing rod 250 is provided at one end of the rotating frame 224 away from the roller 225. When the driving group 230 drives the connecting rod group 220 to move downward, the rotating frame 224 is pressed to rotate horizontally, driving the stabilizing rod 250 to fix the carbon fiber cloth.

[0047] Depend on Figure 7-Figure 8As shown, considering that the surface of the carbon fiber cloth is smooth, the clamping force formed by the roller 225 and the stabilizing rod 250 and the pressure of the stabilizing rod 250 on the carbon fiber cloth are not enough to fix the carbon fiber cloth when the rotating frame 224 moves, and the carbon fiber cloth slides between the roller 225 and the stabilizing rod 250 during the tensioning process. Therefore, the stabilizing rod 250 includes a movable shell 251 and a grabbing rod 253, and a plurality of groups of second springs 252 are fixed between the movable shell 251 and the grabbing rod 253. A plurality of friction blocks are equidistantly fixed on one side of the grabbing rod 253, and a plurality of friction blocks are provided on one side of the movable shell 251 to contact with the grabbing rod. The movable shell 251 has a through slot 254 with the same distance as the friction block of the grab bar 253, and a third sliding cavity 255 is provided on both sides of the movable shell 251. The two ends of the grab bar 253 pass through the third sliding cavity 255 and are fixed to the end of the rotating frame 224 away from the roller 225. When the rotating frame 224 is pressed and rotates horizontally and moves to one side, the movable shell 251 contacts the carbon fiber cloth and is forced to slide along the third sliding cavity 255, driving the friction block fixed on one side of the grab bar 253 to be exposed from the through slot 254 of the movable shell 251, thereby increasing the friction force of the rotating frame 224 on the carbon fiber cloth, thereby fixing the carbon fiber cloth.

[0048] Depend on Figure 3-Figure 4 As shown, in order to realize the tensioning of the carbon fiber cloth by the connecting rod group 220, the driving group 230 includes two driving members 232, each of which is provided with a hydraulic rod 231 above, and third installation cavities 234 are symmetrically provided on both sides of the driving members 232, and the upper end of the main rod 221 is rotatably connected to the third installation cavity 234.

[0049] A support rod 222 is provided on one side of both ends of the main rod 221, wherein a first spring 223 is provided between the support rod 222 at the upper end of the main rod 221 and the driving member 232, and between the support rod 222 at the lower end of the main rod 221 and the rotating frame 224. When the driving group 230 drives the connecting rod group 220 to continue to move downward, the main rod 221 rotates in a direction away from the driving member 232, and at the same time drives the rotating frame 224 to move in the same direction, thereby tensioning the carbon fiber cloth.

[0050] The fixed cutting group 200 includes a transverse column 210, in which a second installation cavity 211 is provided. One end of a hydraulic rod 231 is fixed in the second installation cavity 211, and first sliding cavities 212 are symmetrically provided on both sides of the second installation cavity 211; a sliding block 233 is symmetrically provided on one side of the driving member 232, and the sliding block 233 is slidably connected in the first sliding cavity 212 to limit the sliding direction of the driving member 232.

[0051] Depend on Figure 4-Figure 10As shown, taking into account the mobile cutting of the carbon fiber cloth and avoiding the cutting device from cutting the conveyor belt 103 during cutting, causing damage to the surface of the conveyor belt 103 or the conveyor belt 103 being cut off as a whole, a guide rail 235 is provided between the driving members 232, and the cutting member 240 includes a main body 241, and a track cavity 242 is provided in the main body 241. The guide rail 235 is slidably connected in the track cavity 242 to limit the moving direction of the cutting member 240.

[0052] A laser cutter 244 and a separator 245 are provided below the main body 241 . A second sliding cavity 243 is provided on one side below the track cavity 242 . The separator 245 is slidably connected in the second sliding cavity 243 to limit the moving direction of the separator 245 .

[0053] The separator 245 includes a base 247. The cutting point of the laser cutter 244 faces the base 247. A separator 246 is fixed above the base 247. Limiting blocks 248 are fixed on both sides of the separator 246. A plurality of balls 249 are provided below the base 247. The balls 249 are used to keep the cutting piece 240 stable when the conveying group 102 moves and the cutting piece 240 performs transverse cutting of the carbon fiber cloth.

[0054] Depend on Figure 2 As shown, considering the transmission of carbon fiber cloth, the transmission group 102 includes a conveyor belt 103 and a first motor 104. A first installation cavity 105 is provided on one side of the machine base 101. The conveyor belt 103 is installed in the first installation cavity 105. The output shaft of the first motor 104 is fixed to the driving shaft of the conveyor belt 103.

[0055] A roller 225 is provided at one end of the rotating frame 224 that is in contact with the surface of the conveying group 102, and a second motor 226 is provided at one end of the roller 225. The second motor 226 drives the roller 225 close to the conveying group 102 to rotate in the same direction as the conveying group 102, guiding the moving direction of the carbon fiber cloth so that the carbon fiber cloth passes through the space formed between the roller 225 and the stabilizing rod 250.

[0056] Example 2

[0057] This embodiment provides a method for using a carbon fiber cloth processing device based on positioning cutting according to the content of the above embodiment 1, and the specific steps are as follows:

[0058] S1, start the first motor 104 and the second motor 226, place the carbon fiber cloth on the conveyor belt 103, and the conveyor belt 103 drives the carbon fiber cloth to move toward the roller 225, and when the carbon fiber cloth contacts the roller 225, the roller 225 and the conveyor belt 103 synchronously drive the carbon fiber cloth to pass over the roller 225 and continue to move forward until it passes through the connecting rod assembly 220;

[0059] S2, stop the first motor 104 and the second motor 226, start the hydraulic rod 231, and the hydraulic rod 231 performs hydraulic movement, so that the driving member 232 moves up and down in the first sliding cavity 212 of the horizontal column 210, and drives the rotating frame 224 of the connecting rod group 220 to rotate horizontally, so that the stabilizing rod 250 of the rotating frame 224 exerts a downward pressure on the carbon fiber cloth;

[0060] S3. During the continuous descent of the driving member 232, the main rod 221 rotates in the direction away from the driving member 232 and drives the roller 225 in the rotating frame 224 to move in the same direction. At the same time, the movable shell 251 of the stabilizing rod 250 is forced to move along the third sliding cavity 255, so that the friction block on one side of the grab bar 253 in the movable shell 251 is exposed from the through groove 254 of the movable shell 251 and presses against the carbon fiber cloth, thereby increasing the friction force of the rotating frame 224 on the carbon fiber cloth, and finally the carbon fiber cloth is tensioned;

[0061] S4, start the cutting piece 240, and the laser cutter 244 in the cutting piece 240 cuts the carbon fiber cloth transversely along the guide rail 235. At the same time, the separating piece 245 on one side of the laser cutter 244 moves with the laser cutter 244 to separate the carbon fiber cloth cut by the laser cutter 244.
