[0026] A lead screw 1001 is rotatably connected to the inside of one side of the frame 10 , and a slider 1002 is slidably connected to the other side of the frame 10 .
[0027] The clamp assembly 11 is integrally connected with the nut and the slider 1002 on the surface of the lead screw 1001 through the clamping groove 1101 provided therein, and the clamping groove 1101 is fittedly connected with the clamping plate 1103 through the third cylinder 1102 provided on one side thereof.
[0028] A fourth cylinder 1201 and a telescopic support rod 1202 are respectively provided at the bottom of the lower tensioning roller 12 , and the telescopic support rod 1202 is located at both ends of the fourth cylinder 1201 .
[0029] The top of the upper tensioning roller 13 is rotatably connected with a screw rod 1301 , which passes through the axis of the internal thread gear 1302 and is threadedly connected with its inner wall. One end of the external part of the internal thread gear 1302 is meshedly connected with a driving gear 1303 .
[0030] In this embodiment, Figure 2As shown, the outside of the conveying roller 3 is covered with a conveyor belt, and the conveying rollers 3 are connected by a sprocket assembly 2 to form a transmission structure, and the distance between the conveying rollers 3 is consistent with the distance between the push roller 4 and the pressure roller 5. At the same time, one side of the cutting table 9 is arc-shaped and fits on one side of the push roller 4; the combed fiber bundle is put in through one side of the feed box 1, and the sprocket assembly 2 is fixed to one of the upper and lower groups of conveying rollers 3 through an axle rod, thereby achieving the purpose of conveying materials. At the same time, when the raw material reaches the push roller 4, it is pushed to the surface of the cutting table 9 through its rolling structure, and one side of the cutting table 9 is arc-shaped and fits on one side of the push roller 4 to make the transportation between materials smoother.
[0031] In this embodiment, Figure 2 As shown, the pressing roller 5 is rollingly connected to the shaft heads at both ends thereof, and the two ends of the pressing roller 5 are respectively provided with support slide blocks 14 glued to the shaft heads, and one end of the first cylinder 6 passes through the feed box 1 and is integrally connected with the support slide block 14, and at the same time, the pressing roller 5 forms a lifting structure on the surface of the pushing roller 4 through the first cylinder 6; the rotating structure of the pushing roller 4 can continue to push the fiber raw material, and at the same time, the pressing roller 5 assists in the transportation of the raw material by fitting the raw material continuously transported between it and the pushing roller 4 with a driven rolling motion structure, and when it is transported to the required shearing specifications, the pushing roller 4 stops rotating and uses the first cylinder 6 to make the pressing roller 5 descend and fit the surface of the pushing roller 4, so that the fiber material between them will be tightly pressed, and the pressing roller 5 not only achieves the structure of assisting in pushing the raw material, but also plays the role of fixing and limiting.
[0032] In this embodiment, Figure 3 As shown, the clamp assembly 11 forms a transmission structure through a lead screw 1001 and a slider 1002, and the clamping plate 1103 forms an opening and closing structure with the clamping groove 1101 through a third cylinder 1102, and the highest point of the inner wall surface of the clamping groove 1101 is at the same horizontal position as the surface of the cutting table 9, and at the same time, the surface of the clamping groove 1101 and the clamping plate 1103 at the joint position are respectively covered with a corrugated rubber strip; when the inner wall of the clamping groove 1101 is in contact with the cutting table 9 at the same horizontal position, when the fiber bundle pushed by the push roller 4 falls on the surface of the cutting table 9 During the continuous pushing process, it will fall into the clamping groove 1101, and the clamping plate 1103 can be tightly closed with the clamping groove 1101 through the pneumatic structure. At the same time, the rubber strip coated on the inner wall increases the friction coefficient between the fiber bundle and the fiber bundle, thereby improving the clamping force of the fiber bundle. After the raw material is clamped, it is pulled by the transmission structure. Since one end of the fiber bundle is compacted by the pressing roller 5 and the pushing roller 4, the clamp assembly 11 can effectively straighten and tighten the fiber through the transmission structure when pulling the fiber bundle clamped at the other end to improve its ductility.
[0033] In this embodiment, Figure 4As shown, the lower tensioning rollers 12 are horizontally distributed and arranged in a triangle with the upper tensioning roller 13, and the lower tensioning rollers 12 are respectively formed into a lifting structure through the fourth cylinder 1201; since the fiber bundle being stretched is suspended, in order to avoid the lack of stability of the lower tensioning roller 12 through the fourth cylinder 1201, which leads to uneven pressure when contacting with the fiber bundle, telescopic support rods 1202 are added on both sides thereof to improve its balance stability during operation, so as to achieve more uniform pressure on the fiber bundle when contacting with the fiber bundle, thereby improving production quality.
[0034] In this embodiment, Figure 5 As shown, a servo motor is installed at the axis of the driving gear 1303, and the internal threaded gear 1302 forms a rotating structure through the driving gear 1303, and the screw 1301 forms a transmission structure through the internal threaded gear 1302, and the upper tensioning roller 13 forms a lifting movement; in order to prevent the structure of the upper tensioning roller 13 from affecting the transmission of the clamp assembly 11, the structure of the screw 1301 is used to drive the upper tensioning roller 13 to apply pressure from above, and the structure in which the upper tensioning roller 13 and the lower tensioning roller 12 are staggered and arranged in a triangular shape applies a certain pressure to the fiber bundle from the upper and lower sides during the stretching process, thereby increasing its stretching strength, which helps to improve the strength and elasticity of the fiber, thereby improving the quality of the material, and at the same time, the three sets of tensioning structures can be adjusted separately, and the operator can intuitively make corresponding adjustment measures according to the stretching degree of the fiber bundle, and then the stretching process can be optimized by separate adjustment according to different processing conditions to achieve the best processing effect of the product.
[0035] The use method and advantages of the utility model: The working process of the stretch cutter which is easy to adjust the tension is as follows:
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, the combed fiber bundle raw material is put into one end of the feed box 1, and the sprocket assembly 2 is driven by the servo motor to rotate so that the two groups of conveying rollers 3 connected thereto rotate at the same time, and then the belt outside the conveying roller 3 drives the raw material between them to be pushed inward under the transmission structure, and is transmitted to the surface of the pushing roller 4, and the pushing roller 4 driven by the servo motor continues to push the raw material to the cutting table 9 under the transmission structure. At the same time, one end of the raw material will fall into the inside of the clamping groove 1101 during continuous pushing, and the third cylinder 1102 will drive the clamping plate 1103 to close the clamping groove 1101 to clamp one end of the raw material inside. It should be noted that the surface of the pushing roller 4 The surface is provided with a rotary encoder (model E6B2-C2Z6C), and its principle is that it will output a series of pulse signals as the push roller 4 rotates. The number of revolutions of the push roller 4 can be determined by counting the pulses, and since the circumferences of the two bottom surfaces of the push roller 4 are fixed, the length of the raw material pushed by the push roller 4 can be calculated according to the diameter specification of the push roller 4. The surface parts of the push roller 4 are electrically connected to the external control system. After the control system calculates, it can turn off the servo motor driving the push roller 4 to stop it from continuing to push the raw material, and drive the first cylinder 6 to make the pressure roller 5 fit and mortgage on the surface of the push roller 4, clamping one end of the fiber bundle, and at the same time At the same time, the pre-fixed clamp assembly 11 will drive one end of the raw material from one side of the cutting table 9 to the other side of the frame 10 through the transmission structure of the lead screw 1001 and the slider 1002 on the other side. The fiber bundles fixed at both ends will be stretched through the transmission structure. The operator can adjust the lower tensioning roller 12 and the upper tensioning roller 13 according to the stretching condition of the fiber bundle. The lower tensioning roller 12 will push upward through the fourth cylinder 1201 to apply pressure to the lower surface of the fiber bundle, and the telescopic support rods 1202 on both sides will stretch together with it as it rises, thereby improving the balance stability during operation at both ends, so as to achieve a more uniform pressure on the fiber bundle when in contact with the fiber bundle. At the same time, the servo motor driving gear 1303 rotates to rotate the internal thread gear 1302 meshing with it. Under the threaded structure, the screw 1301 drives the upper tensioning roller 13 to apply pressure downward from the upper surface of the fiber bundle, thereby increasing its stretching force, which helps to improve the strength and elasticity of the fiber. After completing the stretching of this section of material, the second cylinder 7 drives the tool 8 to shear at one end of the pushing roller 4 and then completes the second round of stretching and shearing process again. It should be noted that each group of cylinder components and servo motors of the equipment are electrically connected to the external control system, which is a prior art and can effectively reduce manual intervention and provide convenience in the operation process.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
