Description

Technical Field

[0002] Glass fiber reinforced plastic (GFRP), a core material for lightweight structures, is widely used in aerospace, new energy vehicles, and other fields. Its cutting quality directly affects component fatigue strength and assembly accuracy, with strict standards for edge burr content and length tolerances being particularly demanding. However, existing cutting equipment still has some drawbacks, specifically: First, when the existing device is cutting, the cutting edge of the tool will squeeze the resin matrix, causing the glass fiber to be pulled out before it is cut, forming a "whisker-like" burr defect. After cutting, it needs to be polished several times before it can be used.

[0003] Secondly, traditional equipment relies on the feed roller encoder to indirectly calculate the length, but the friction coefficient between the coil and the drive roller fluctuates, resulting in the actual feed length being less than the encoder count, which can easily lead to different storage amounts for each group of coils, affecting the average degree.

[0023] It should be noted that the front of the isolation cover 11 is hinged with a box door, which is designed to facilitate the maintenance of the internal device; The box door of the isolation cover 11 is made of transparent material, which is convenient for observing the processing situation inside.

[0024] In this embodiment, when in use, the winding disc for receiving the composite material is placed on the storage tray 15, then the lifting frame 53 is pulled up, and the storage tray 15 on the lifting frame 53 is inserted into the other end of the winding disc, then the winding disc is connected with the composite material, the conveying roller 21 runs to convey the material, and the length of the conveying is recorded by the counter 24, at the same time, the arc-shaped frame 62 also adheres to the inside of the winding disc, and gradually moves to the right side with the receiving of the composite material, until the counter 24 records the appropriate number, and the arc-shaped frame 62 also touches the switch 66, indicating that the receiving length has reached the appropriate number, at this time, the control assembly 30 operates to fix the two ends of the composite material, at the same time, the control assembly 30 drives the blade 43 to approach the material, then the heating disc 44 operates to heat the blade 43, and the blade 43 after heating is used to cut the material, which produces a slight heat melting phenomenon on the cutting surface of the material, thereby reducing the generation of burrs.

[0025] Secondly, please refer to Figures 1 to 3 , Figure 12The upper end of the rear side of the bracket two 13 is fixedly provided with a motor one 14, the output shaft of the motor one 14 is fixedly connected with the rotating shaft of the receiving disc 15 and penetrates the bracket two 13, two groups of hollow grooves are formed in the axis of the receiving disc 15, two groups of convex strips 16 are slidably connected in the two groups of hollow grooves, the middle part of the end of the two groups of convex strips 16 extending out of the inner cavity of the receiving disc 15 is fixedly connected with a spring one 17, and the other end of the spring one 17 is fixedly connected in the middle part of the inner cavity of the receiving disc 15.

[0026] It should be noted that the upper end of the convex strip 16 is provided with an inclined slope, and the bottom end of the inclined slope is close to the outer side of the receiving disc 15, which is designed to enable the convex strip 16 to be squeezed into the groove in the inner ring of the winding disc for adaptive fixing when the winding disc of different sizes is installed, so as to avoid the winding disc of different sizes from being unable to be installed. The lower end of the convex strip 16 is fixedly connected with two limiting strips, which is designed to limit the movement range of the convex strip 16 and avoid the convex strip 16 from completely extending out of the receiving disc 15 to affect the use.

[0027] Preferably, in order to ensure the normal operation of the device, a device for receiving waste materials should be placed below the discharging groove 18 to avoid the waste materials from spreading everywhere and affecting the surrounding environment.

[0028] In this embodiment, when in use, the winding disc for receiving composite materials is placed on the receiving disc 15, at this time, the groove in the inner ring of the winding disc will squeeze the convex strip 16, so that the convex strip 16 shrinks into the hollow groove of the receiving disc 15, when the winding disc is completely placed, the spring one 17 pushes the convex strip 16 to rebound and is clamped in the groove in the inner ring of the winding disc, so as to realize the fixation of winding discs of different sizes and avoid the winding disc from deviating when receiving materials. Then the motor one 14 drives the receiving disc 15 to rotate to perform the receiving work of the composite materials.

[0029] Secondly, referring again to Figures 3 to 4 The conveying roller 21 is provided in two groups and is distributed in the middle part of the inner cavity of the bracket one 12 in an up-down manner, the driving assembly 20 further comprises a gear one 22, the rear end of the two groups of conveying rollers 21 is fixedly connected with the gear one 22 penetrating the bracket one 12, the outer rings of the two groups of gear ones 22 are meshed together, the upper end of the rear side of the bracket one 12 is fixedly provided with a motor two 23, and the output shaft of the motor two 23 is fixedly connected with the center of the gear one 22 located on the upper side; The driving assembly 20 further comprises a gear two 25, the gear two 25 is fixedly connected with the rotating shaft of the counter 24, and the axis of the gear one 22 located on the lower side is fixedly connected with a gear three 26, the outer ring of the gear three 26 is meshed with a chain 27, and the inner ring of the lower end of the chain 27 is meshed with the outer ring of the gear two 25.

[0030] It should be noted that the outer ring of the conveying roller 21 is provided with a rubber anti-skid pad, and the distance between the two groups of conveying rollers 21 should be less than 1mm, which aims to convey the composite material by the conveying roller 21, and to enhance the friction and elasticity by the rubber anti-skid pad, so as to cope with composite materials of different thicknesses; The outer diameter of gear two 25 is the same as that of gear three 26, aiming to make the rotation speed and number of turns of the counter 24 the same as the rotation speed of the conveying roller 21; The counter 24 is a device for judging the conveying length of the composite material by counting the number of turns of the gear two 25, and uses the anti-skid pad on the outer ring of the conveying roller 21 to improve the accuracy of the calculation and reduce the occurrence of composite material slipping, pulling and transverse movement.

[0031] Preferably, in order to prolong the service life of the device, protective shells can be installed on the outer rings of each group of gears and chains 27 to isolate them, so as to prevent glass fibers from falling into the gaps of the structures and affecting use.

[0032] In this embodiment, in use, the motor two 23 drives the upper gear one 22 to rotate and synchronously drives the lower gear one 22 to rotate, at this time the two groups of conveying rollers 21 will rotate with the rotation of the two groups of gear one 22, thereby conveying the composite material, and the lower gear one 22 will drive the gear three 26 to rotate, the gear three 26 will drive the gear two 25 to rotate through the chain 27, thereby making the counter 24 rotate with the rotation of the conveying roller 21, and recording the number of turns, and the length of the composite material conveyed by the conveying roller 21 can be known by calculating the number of turns.

[0033] Secondly, please refer to Figures 5 to 7 , the control assembly 30 further comprises two groups of extrusion frames 31, which are respectively installed on the left and right sides of the lower end of the inner cavity of the isolation cover 11, and the inner cavities of the two groups of extrusion frames 31 are both slidingly connected with lifting blocks 32, the middle parts of the two groups of lifting blocks 32 and the middle parts of the extrusion frames 31 are both fixedly connected with extrusion rollers 33, and the two groups of extrusion rollers 33 are distributed above and below, the inner cavity of the upper end of the isolation cover 11 is fixedly installed with an electric guide rail 34, a sliding block in the inner cavity of the electric guide rail 34 is fixedly installed with an electric push rod 35, and the lower end of the electric push rod 35 is fixedly connected with an assembly plate 36.

[0034] It should be noted that the inner cavity of the extrusion frame 31 is built-in with a pneumatic telescopic rod (as shown in Figure 5 ), aiming to drive the lifting block 32 to lift and operate by the pneumatic telescopic rod, and a control device should be arranged in series between the front and rear two groups of extrusion frames 31 to ensure that the two groups of lifting blocks 32 can lift synchronously; The electric guide rail 34 is an electric drive sliding rail, aiming to adjust the position of the electric push rod 35 by the electric guide rail 34; The outer ring of the extrusion roller 33 is provided with a non-slip material pad, which is designed to fix the composite material with the extrusion roller 33, avoid slipping or deviation of the composite material during cutting, cause damage to the material during cutting, affect the use effect, and also fix the composite material to reduce the slipping and deviation of the material in the conveying roller 21, improve the accuracy; In use, the left extrusion roller 33 can first drive the material to be clamped and fixed, and then the material can be pulled tight by the rotation of the motor 14 before the right extrusion roller 33 is driven to fix the material, improving the tightness of the material during cutting and improving the flatness of the cut.

[0035] In this embodiment, after the material is conveyed, the extrusion frame 31 drives the lifting block 32 to lower the extrusion roller 33 to clamp and fix the composite material. At this time, the electric guide rail 34 drives the electric push rod 35 to move the assembly plate 36 until the blade 43 is above the composite material, and then the electric push rod 35 drives the blade 43 to approach the material. After cutting is completed, the electric guide rail 34 drives the electric push rod 35 to reset, releasing the fixation of the composite material, and then the motor 14 drives the storage disc 15 to continue rotating for the next round of composite material storage work.

[0036] Please refer again to Figures 5 to 7 The mounting frame 41 is installed at the lower end of the assembly plate 36, and the cutting assembly 40 further comprises a control component 42 installed at the left side of the mounting frame 41, and the output shaft of the control component 42 is fixedly connected with the rotating shaft of the blade 43. The cutting assembly 40 further comprises a gas pipe 45 fixedly connected at the middle of the assembly plate 36, and the upper end of the gas pipe 45 extends out of the isolation cover 11 and is fixedly connected at the left upper end of the isolation cover 11. The lower end of the gas pipe 45 is provided with two groups of air inlets, and each of the two groups of air inlets is communicated with an adsorption cover 46.

[0037] It should be noted that the control component 42 is a component for driving the blade 43 to operate and controlling the use of the heating disc 44; The heating disc 44 is an electric heating assembly with an electric heating wire built-in; The temperature range of the heating disc 44 during operation should be controlled between 100℃ and 120℃, which is designed to heat the blade 43 with the heating disc 44, so that a slight hot melting phenomenon can be formed on the surface of the material during cutting, reducing the burr of the cutting surface of the composite material; The adsorption cover 46 is provided with two groups, and the inlet of each of the two groups of adsorption covers 46 faces the lower end of the blade 43, which is designed to adsorb the debris generated during cutting with the adsorption cover 46; The gas pipe 45 is a relatively hard hose, which is designed to move with the assembly plate 36 when the assembly plate 36 moves, avoiding damage, and using the relatively hard material of the gas pipe 45 to avoid the inner wall bending and fitting, affecting the dust collection effect.

[0038] Preferably, the device needs to be connected with a suction component such as an air pump during use, and the component is communicated with the air pipe 45 (this is a common technical structure in the prior art, but more elaboration is not needed), and then the suction component can be used to suck the debris generated during cutting through the air pipe 45 and the suction cover 46.

[0039] In this embodiment, when cutting, the heating disc 44 operates to preheat the blade 43, and when the temperature of the blade 43 reaches a preset range, the control component 42 drives the blade 43 to rotate, thereby cutting the composite material below. At this time, the external air pump transports negative pressure to the suction cover 46 through the air pipe 45, so that the suction cover 46 generates suction force to suck the debris generated during cutting, avoiding the debris flying everywhere and affecting the working environment. The heated blade 43 will cause slight heat melting phenomenon on the cutting surface of the material during cutting, so that the fibers on the cutting surface are fused and adhered, thereby reducing the generation of burrs and improving the flatness of the cutting surface.

[0041] It should be noted that the moving block 52 is a cross-shaped block, which is designed to allow the moving block 52 to slide in the sliding groove 51 and prevent the moving block 52 from coming off the sliding groove 51; Here, in order to ensure that the moving block 52 can be fixed at different positions, a locking assembly should be installed on the moving block 52, such as a manual guide rail lock and a clamp.

[0042] The length of the storage disc 15 on the sliding block 55 should be less than that of the storage disc 15 on the support two 13, which is designed to use the two sets of storage discs 15 to limit the two ends of the winding disc and improve the stability of the limiting disc when rolling; The upper end of the lifting frame 53 and the upper end of the inserting rod 57 are provided with a handle, which is used to pull the lifting frame 53 and the inserting rod 57 upwards.

Then, the inserting rod 57 is pulled upwards to be separated from the inserting slot 56, and then the sliding block 55 is pushed to make the receiving disc 15 on the sliding block 55 inserted into the winding disc to stabilize the other end of the winding disc, and then the inserting rod 57 is released, and the spring 58 pushes the inserting rod 57 to rebound into the inserting slot 56 to fix the sliding block 55, at which time the two sets of receiving discs 15 limit the two ends of the winding disc to improve the stability of the winding disc when rotating. After the winding disc is received, the handle 59 is pulled to make the sliding block 55 slide on the lifting frame 53, so that the sliding block 55 and the receiving disc 15 on the upper end of the sliding block 55 are separated from the winding disc, and then the lifting frame 53 is lowered to reset, and then the received winding disc can be disassembled.

[0045] It should be noted that the switch 66 is a component for controlling the opening and closing of the motor 14, and an alarm component such as an alarm lamp can be externally connected when in use, so that the motor 14 can be controlled to stop running when the arc-shaped frame 62 hits the switch 66, and an alarm can be given to the staff; The arc-shaped frame 62 is provided with an arc-shaped plate near one end of the support 13, and the upper and lower ends of the arc-shaped plate are smoothly treated, aiming to make the winding disc gradually widen in diameter when rotating to store the composite material, so as to push the arc-shaped frame 62 to move, until the winding disc is stored to the appropriate outer diameter width, the arc-shaped frame 62 will contact the switch 66, and then the arc-shaped frame 62 and the conveying roller 21 are used to improve the accuracy and uniformity of each group of winding discs to store the composite material; The spring 63 is used to improve the close degree of the composite material when the winding disc rotates to store; The surface of the sliding frame 65 is provided with a scale groove (as shown in Figure 14 The scale groove is used to accurately position the position of the sliding frame 65, so as to cope with winding discs of different models and storage needs; The left end of the lead screw 67 is provided with a handle, aiming to facilitate the rotation of the lead screw 67; The cable 68 is made of soft material, which can avoid damage to the cable 68 when the sliding frame 65 moves, and aims to transmit the signal released by the switch 66 through the cable 68.

[0046] In this embodiment, the rotating lead screw 67 drives the sliding frame 65 to slide left and right in the through groove, and then the position of the switch 66 can be adjusted to facilitate the winding discs with different storage needs. When the winding disc rotates to store the composite material, the gradually widening outer diameter will push the arc-shaped frame 62 to move to the right, and when the winding disc is stored to the appropriate outer diameter, the arc-shaped frame 62 will touch the switch 66 at the upper end of the sliding frame 65, at this time the switch 66 controls the motor 14 to stop running and sends an alarm to prompt the staff that the winding disc is stored. At the same time, the double verification method of the arc-shaped frame 62 and the conveying roller 21 can improve the accuracy and uniformity of each group of winding discs to store the composite material.

[0047] The working principle of the present application is as follows: when in use, the winding disc for accommodating composite materials is placed on the accommodating disc 15, at this time the groove in the inner circle of the winding disc will extrude the convex strip 16, so that the convex strip 16 shrinks into the empty groove of the accommodating disc 15, and when the winding disc is completely placed, it is fixed in the groove in the inner circle of the winding disc, then the moving block 52 is pushed to make the lifting frame 53 close to the other end of the winding disc, and the lifting frame 53 is pulled up to contact the other end of the winding disc. Then the pull-up plug rod 57 is pulled out of the plug groove 56, then the sliding block 55 is pushed to make the accommodating disc 15 on the sliding block 55 inserted into the winding disc, and the other end of the winding disc is stabilized. Then the screw rod 67 is rotated to drive the sliding frame 65 to slide in the through groove to adjust the position of the switch 66. Then the motor two 23 drives the two sets of conveying rollers 21 to rotate to convey the composite materials, and at the same time, the gear one 22 below drives the gear three 26 to rotate, so that the counter 24 can record the number of rotations of the conveying roller 21, and the length of the composite materials conveyed by the conveying roller 21 can be known by calculating the number of rotations. And when the winding disc rotates to accommodate the composite materials, the outer diameter gradually increases to push the arc-shaped frame 62 to move to the right, and when the winding disc is accommodated to the appropriate outer diameter, the arc-shaped frame 62 will touch the switch 66 at the upper end of the sliding frame 65, at this time the switch 66 controls the motor one 14 to stop running and sends out an alarm to prompt the staff that the winding disc is completed. Further, the double verification method is used to improve the accuracy and uniformity of the number of winding discs accommodated in each set. After the accommodation is completed, the extrusion frame 31 drives the lifting block 32 and the extrusion roller 33 to descend to clamp and fix the composite materials, at the same time, the electric guide rail 34 drives the electric push rod 35 to move the assembly plate 36 until the blade 43 is above the composite materials, then the electric push rod 35 drives the blade 43 to approach the materials, the heating disc 44 operates to preheat the blade 43, when the temperature of the blade 43 reaches the preset range, the control component 42 drives the blade 43 to rotate to cut off the composite materials below. At this time, the external air pump absorbs the debris generated during cutting through the air pipe 45 and the adsorption cover 46. After cutting is completed, the electric guide rail 34 drives the electric push rod 35 to reset to release the fixation of the composite materials, then the motor one 14 drives the accommodating disc 15 to continue rotating to accommodate the remaining materials, and waits for the next round of composite material accommodation work.
