Description

Technical Field

[0001] This utility model relates to the field of glass fiber tube processing technology, and in particular to a glass fiber tube cutting device. Background Technology

[0002] The continuous production process of fiberglass tubes typically includes the following steps: fiber impregnation, mandrel forming, curing oven shaping, traction, online length cutting, and stacking. The online length cutting station, located downstream of the traction device, is used to cut the continuously cured fiberglass tubes to a preset length. Its precision and stability directly affect the geometric quality of the finished product and its subsequent assembly performance.

[0003] In existing technologies, the traction and fixed-length cutting of fiberglass tubes generally employs a "traction-synchronous cutting" scheme. The traction device clamps the outer side of the fiberglass tube, conveying it from front to back while maintaining axial tension, keeping the tube straight. The cutting device typically includes a cutting frame that can slide back and forth on a linear guide rail, a clamping mechanism mounted on the cutting frame, a cutting mechanism mounted on the cutting frame, and a resetting mechanism for moving the cutting frame forward and resetting. When cutting is required, the clamping mechanism clamps the outer side of the fiberglass tube, causing the cutting frame and the fiberglass tube to move synchronously. Then, the cutting mechanism begins to cut the fiberglass tube. The clamping mechanism releases its grip on the fiberglass tube, and the resetting mechanism drives the cutting frame to reset, entering the next work cycle.

[0004] However, the aforementioned "traction-synchronous cutting" method has significant drawbacks in actual production. First, the traction device has already established axial tension inside the fiberglass tube. During cutting, the clamping mechanism of the cutting device tightens again, resulting in the tube being double-clamped from both ends at the same axial position. The instantaneous speed difference and sudden change in clamping force can easily cause a large impact on the tube wall, which can easily lead to local dents, deformation, or cracking, reducing the appearance quality of the fiberglass tube. Second, the clamping mechanism of the cutting device is prone to leaving scratches on the outer surface of the fiberglass tube during high-speed clamping, further reducing the appearance quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass fiber tube cutting device that can improve the appearance quality of glass fiber tubes.

[0006] To solve the above-mentioned technical problems, the present invention provides a glass fiber tube cutting device, including a conveying frame, a cutting assembly, and multiple sets of traction assemblies arranged at intervals in front of the cutting assembly. The traction assembly includes a traction frame slidably connected to the conveying frame, a synchronous arm fixed on the traction frame and extending rearward, a clamping mechanism mounted on the traction frame for clamping the glass fiber tube, and a translational drive mechanism mounted on the conveying frame for driving the traction frame to move back and forth. The cutting assembly includes a cutting frame slidably connected to the conveying frame, a cutting mechanism mounted on the cutting frame for cutting the glass fiber tube, a reset mechanism mounted on the cutting frame for driving the cutting frame to reset, and multiple sets of clamping mechanisms for clamping multiple sets of synchronous arms one-to-one.

[0007] As an improvement to the above solution, a synchronous arm is provided on both the left and right sides of the traction frame, and each clamping mechanism includes two clamping members that are applied to clamp the two synchronous arms.

[0008] As an improvement to the above solution, the synchronous arms of the multiple traction frames are arranged at vertical intervals.

[0009] As an improvement to the above solution, the clamping component includes two clamping blocks for correspondingly clamping the left and right sides of the synchronous arm, and a clamping cylinder mounted on the cutting frame for driving the clamping blocks to open and close.

[0010] As an improvement to the above solution, the left and right sides of the synchronizing arm are outwardly convex arc surfaces, and the inner side of the clamping block is provided with an arc groove that matches the arc surface.

[0011] As an improvement to the above solution, the cutting frame is horizontally rotatably connected to two support rollers that are spaced apart front to back and used to support the lower side of the glass fiber tube, and the cutting mechanism is positioned between the two support rollers.

[0012] As an improvement to the above solution, the cutting mechanism includes a slide block that is slidably connected to the cutting frame, a saw mounted on the slide block, a lead screw that is rotatably connected to the cutting frame and threadedly connected to the slide block, and a servo motor mounted on the cutting frame for driving the lead screw to rotate.

[0013] As an improvement to the above solution, the cutting frame is vertically rotatably connected to two limiting rollers for abutting against the left or right side of the glass fiber tube, and the cutting mechanism is positioned between the two limiting rollers.

[0014] Implementing this utility model has the following beneficial effects:

[0015] This utility model discloses a glass fiber tube cutting device. Through the cooperation of a conveyor frame, a cutting component, multiple sets of traction components, multiple sets of synchronous arms, and multiple sets of clamping mechanisms, during the glass fiber tube cutting process, only the clamping mechanism of the traction component clamps the outside of the glass fiber tube, reducing the impact force on the glass fiber tube, reducing the occurrence of local dents, deformation, or cracks in the glass fiber tube, and at the same time reducing the clamping of the outside of the glass fiber tube on the cutting frame, reducing the scratches left on the outer surface of the glass fiber tube, and improving the appearance quality of the glass fiber tube.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0030] like Figures 1 to 6 As shown in the figure, a glass fiber tube cutting device according to an embodiment of the present invention includes a conveying frame 100, a cutting assembly 200, and multiple sets of traction assemblies 300 spaced apart in front of the cutting assembly 200. The traction assembly 300 includes a traction frame 310 slidably connected to the conveying frame 100, a synchronous arm 320 fixed on the traction frame 310 and extending rearward, a clamping mechanism 340 mounted on the traction frame 310 for clamping the glass fiber tube, and a translational drive mechanism 330 mounted on the conveying frame 100 for driving the traction frame 310 to move back and forth. In practice, the clamping mechanism 340 may include an upper clamping block, a lower clamping block, and a clamping drive cylinder for driving the upper and lower clamping blocks to open and close, capable of clamping the outer side of the glass fiber; the translational drive mechanism 330 may be a hydraulic push rod or a single-axis translation stage, capable of driving the traction frame 310 to move back and forth.

[0031] It should be noted that the traction assembly 300 has at least two sets for continuously conveying the glass fiber from front to back. Taking two sets of traction assemblies 300 as an example, their working principle is as follows: First, the clamping mechanism 340 of one set of traction assemblies 300 clamps the glass fiber tube and, under the action of the translation drive mechanism 330, moves the glass fiber tube from front to back. The other set of traction assemblies 300 releases the glass fiber tube and remains in place. After conveying a certain distance, the other set of traction assemblies 300 clamps the glass fiber tube in the same way and continues to convey it from front to back, while the initially clamping set of traction assemblies 300 moves forward to reset after releasing the glass fiber tube. In this way, the two sets of traction assemblies 300 work alternately to achieve continuous conveying of the glass fiber tube. When the number of traction assemblies 300 increases, there is always one or more sets of traction assemblies 300 clamping and conveying the glass fiber tube, while the remaining sets of traction assemblies 300 simultaneously release and reset. By staggering the timing (such as the second group being pre-reset while the first group is being conveyed, and the third group being clamped), uninterrupted relay conveying is formed. The redundant design allows for dynamic adjustment of the alternating rhythm, further improving the continuity and efficiency of conveying.

[0032] The cutting assembly 200 includes a cutting frame 210 slidably connected to the conveyor frame 100, a cutting mechanism 220 mounted on the cutting frame 210 for cutting glass fiber tubes, a reset mechanism 230 mounted on the cutting frame 210 for driving the cutting frame 210 to reset, and multiple clamping mechanisms for clamping multiple sets of synchronous arms 320 one-to-one. In practice, the cutting mechanism 220 can be an automatic circular saw or an automatic band saw, capable of moving back and forth on the cutting frame 210 to cut the glass fiber tubes; the reset mechanism 230 can be a hydraulic push rod or a single-axis translation stage, capable of driving the cutting frame 210 forward to reset, with the output end tracking the forward movement of the cutting frame 210.

[0033] The synchronizing arm 320 can be mounted on the traction frame 310 via a connecting frame, and the front-to-back extension range of the synchronizing arm 320 does not exceed the reciprocating stroke of the cutting frame 210. The clamping mechanism 340 can be a pneumatic gripper or an electric gripper, etc., which can clamp the outside of the synchronizing arm 320 so that the cutting frame 210 and the synchronizing arm 320 move synchronously, thereby causing the cutting mechanism 220 mounted on the cutting frame 210 to move backward synchronously with the glass fiber tube conveyed from front to back by the traction assembly 300, reducing the clamping of the outside of the glass fiber tube on the cutting frame.

[0034] At the start of operation, the cutting frame 210 is in its initial position. When the fiberglass tube needs to be cut, the clamping mechanism clamps the synchronous arm 320 of the traction component 300, which is driving the fiberglass tube backward, ensuring that the cutting frame 210 moves backward synchronously with the fiberglass tube. Since the number of clamping mechanisms is the same as the number of traction components 300, when the cutting frame 210 needs to move synchronously with the fiberglass tube, and when the traction component 300 needs to be switched, the corresponding clamping mechanism simultaneously tightens or loosens its clamping of the corresponding synchronous arm 320, ensuring that the cutting frame 210 moves backward synchronously with the fiberglass tube during cutting. During the cutting process of the fiberglass tube, only the clamping mechanism 340 of the traction component 300 clamps the outside of the fiberglass tube, reducing the impact force on the fiberglass tube. When the cutting frame 210 needs to be reset, multiple clamping mechanisms release the corresponding synchronous arms 320, and the reset mechanism 230 drives the cutting frame 210 to reset, ready for the next cutting operation.

[0035] It should be noted that this utility model can be equipped with control components such as PLC (Programmable Logic Controller) or a working device, which can control the coordinated operation of each component, ensure the accuracy of automatic operation of each component, and improve the automation level of the cutting device.

[0036] The glass fiber tube cutting device of this utility model uses a conveyor frame 100, a cutting component 200, multiple sets of traction components 300, multiple sets of synchronous arms 320 and multiple sets of clamping mechanisms to cooperate with each other. During the glass fiber tube cutting process, only the clamping mechanism 340 of the traction component 300 clamps the outside of the glass fiber tube, which reduces the impact force on the glass fiber tube, reduces the occurrence of local dents, deformation or cracks in the glass fiber tube, and at the same time reduces the clamping of the outside of the glass fiber tube on the cutting frame, reduces the scratches left on the outer surface of the glass fiber tube, and improves the appearance quality of the glass fiber tube.

[0037] Specifically, the traction frame 310 preferably has a synchronous arm 320 on both its left and right sides. Each clamping mechanism includes two clamping members 240, one in each pair, used to clamp the two synchronous arms 320. The clamping members 240 can be pneumatic grippers or electric grippers, etc., which can clamp the outer side of the synchronous arm 320 to make the cutting frame 210 move synchronously with the synchronous arm 320. By setting a synchronous arm 320 on each side of the traction frame 310 and cooperating with the two corresponding clamping members 240 of each clamping mechanism, the impact force during clamping is distributed to both sides of the traction frame 310 and both sides of the cutting frame 210, which increases the difficulty of swaying when the traction frame 310 and the cutting frame 210 move and improves the operational stability of the traction frame 310 and the cutting frame 210.

[0038] Preferably, the synchronous arms 320 of the plurality of traction frames 310 are arranged at intervals between each other, so that the synchronous arms 320 between different groups of traction components 300 do not interfere with each other, ensuring that the traction components 300 operate smoothly to continuously transport the glass fiber tube from front to back.

[0039] More specifically, the clamping member 240 preferably includes two clamping blocks 241 for correspondingly clamping the left and right sides of the synchronous arm 320, and a clamping cylinder 242 mounted on the cutting frame 210 for driving the clamping blocks 241 to open and close. In effect, the clamping cylinder 242 and the clamping blocks 241 form pneumatic fingers for clamping the left and right sides of the synchronous arm 320, capable of clamping or releasing the left and right sides of the synchronous arm 320, ensuring that the clamping mechanism can clamp the synchronous arm 320 so that the cutting frame 210 and the traction frame 310 move backward synchronously. Furthermore, the left and right sides of the synchronous arm 320 are preferably outwardly convex arc surfaces 321, and the inner side of the clamping block 241 is provided with an arc groove 243 that matches the arc surface 321. In fact, the radius of the arc of the convex surface 321 is equal to the radius of the arc of the groove 243, so that the convex surface 321 can fit into the groove 243. When the clamping cylinder 242 drives the two clamping blocks 241 to approach each other, the groove 243 and the convex surface 321 form a face-to-face embracing clamp, which increases the contact area, reduces local pressure, and reduces damage to the clamping blocks 241 and the synchronous arm 320.

[0040] It should be noted that the cutting frame 210 is preferably horizontally rotatably connected to two support rollers 211 spaced apart front to back for supporting the lower side of the glass fiber tube, and the cutting mechanism 220 is positioned between the two support rollers 211. During cutting, the two support rollers 211 support the glass fiber tube from bottom to top; during resetting, the support rollers 211 move back with the cutting frame 210 and roll relative to the outside of the glass fiber tube, reducing friction and surface damage.

[0041] Specifically, the cutting mechanism 220 preferably includes a slide 221 slidably connected to the cutting frame 210, a saw 222 mounted on the slide 221, a lead screw 223 horizontally rotatably connected to the cutting frame 210 and threadedly connected to the slide 221, and a servo motor 224 mounted on the cutting frame 210 for driving the lead screw 223 to rotate. During operation, the servo motor 224 converts the rotational motion into left-right movement of the slide 221 relative to the cutting frame 210 via the lead screw 223, causing the saw 222 to move left-right to achieve feeding or resetting, thus cutting the glass fiber tube.

[0042] It is worth mentioning that the cutting frame 210 is preferably vertically rotatably connected with two limiting rollers 212 for abutting against the left or right side of the glass fiber tube, and the cutting mechanism 220 is positioned between the two limiting rollers 212. In fact, as... Figure 2 and Figure 4 As shown, during cutting by the cutting mechanism 220, the servo motor 224 drives the sawing machine 222 to move from left to right via the lead screw 223 and the slide block 221, achieving cutting feed. When cutting the glass fiber tube, the two limiting rollers 212 are positioned on the right side of the glass fiber tube and abut against the right side of the glass fiber tube to reduce deformation of the glass fiber tube during cutting, until the cutting mechanism 220 finishes cutting and moves to the left to reset. Similarly, if the sawing machine 222 moves from right to left during the cutting feed of the cutting mechanism 220, the limiting rollers 212 are correspondingly positioned on the left side of the glass fiber tube and abut against the left side of the glass fiber tube. In addition, when the cutting frame 210 resets, the limiting rollers 212 move back with the cutting frame 210 and roll relative to the outside of the glass fiber tube to reduce friction and surface damage.

[0043] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Although embodiments of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
