Description

Technical Field

[0001] This utility model relates to the field of fiber web cutting technology, specifically a fixed-length cutting structure for preparing composite fiber webs. Background Technology

[0002] In the production and processing of composite fiber mesh, fixed-length cutting is a key step to ensure product specifications are consistent and to meet the needs of subsequent production and application. With the widespread application of composite materials in high-end fields such as aerospace, automobile manufacturing, and construction engineering, the market has increasingly stringent requirements for the quality and cutting precision of composite fiber mesh.

[0003] Traditional composite fiber mesh fixed-length cutting structures mostly adopt simple mechanical and manual cutting methods. These structures have some shortcomings. During the cutting process, due to the lack of effective fiber mesh fixing measures, fiber mesh displacement or wrinkling is very likely to occur, resulting in uneven edges and large dimensional deviations of the cut fiber mesh, which cannot meet high-precision production standards and cause a lot of waste of raw materials. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fixed-length cutting structure for preparing composite fiber mesh, which solves the problem that traditional composite fiber mesh cutting structures lack effective fiber mesh fixing measures and are prone to fiber mesh displacement or wrinkling.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fixed-length cutting structure for preparing composite fiber webs includes: a base, with a conveying roller assembly fixedly connected to the outer wall of the top of the base; and a cutting device, with the outer wall of the bottom of the cutting device fixedly connected to the outer wall of the top of the base. The cutting device includes a cutting seat, with a cutting groove and an inclined groove formed on the outer wall of the top of the cutting seat. Sensors are symmetrically fixedly connected to the outer wall of the top of the cutting seat, and a support plate is symmetrically fixedly connected to the outer wall of the top of the cutting seat. A hydraulic rod is fixedly connected to the outer wall of the top of the support plate, and a mounting block is fixedly connected to the outer wall of the bottom of the hydraulic rod. Bolts are symmetrically threaded onto the inner wall of the mounting block, and a mounting groove is formed on the outer wall of the mounting block. A gate is slidably connected to the inner wall of the mounting groove, and positioning holes are symmetrically formed on the outer wall of the gate.

[0009] Preferably, the outer wall of the bottom of the cutting seat is fixedly connected to the outer wall of the top of the base, the outer wall of the sensor side is fixedly connected to the outer wall of the support plate side, and the sensor is set at both ends of the cutting seat. The sensor adopts a commercially available BGS-ZLN / P type sensor. The sensor has a transmitting lens and a receiving lens inside. In the direction of light emission, the angle at which the light reflected from the target object at different positions hits the receiving lens is different. The receiving lens is a focusing lens, which will focus the light reflected back from the same position onto a certain point on the receiving chip. The position of the focal point on the chip reflects the position information of the measured object. The chip converts the position information into an electrical signal and sends it to the processor. When the set distance is reached, a signal is sent to perform the cutting operation. The outer wall of the guillotine is slidably connected to the inner wall of the cutting groove.

[0010] Preferably, the outer wall of the bottom of the telescopic rod on the hydraulic rod is fixedly connected to the outer wall of the top of the mounting block, the outer wall of the mounting block is slidably connected to the inner wall of the support plate, and the inner wall of the positioning hole is slidably connected to the outer wall of the bolt. When the hydraulic rod is activated, its telescopic rod extends downward, causing the mounting block at the bottom to slide downward along the inner wall of the support plate. The guillotine on the mounting block then moves downward along the inner wall of the cutting groove to cut the fiber web.

[0012] Preferably, the outer wall of the compression spring away from the pressure plate is fixedly connected to the outer wall of the bottom of the horizontal plate, and the outer wall of the bottom of the pressure plate is in contact with the outer wall of the top of the cutting seat. During the cutting process, the pressure plate at the bottom of the sliding rod on the horizontal plate of the mounting block first contacts the fiber web. As the pressure plate continues to press down, the compression spring is compressed, and the pressure plate presses the fiber web tightly onto the cutting seat to prevent the fiber web from moving during cutting and to ensure the accuracy of cutting.

[0013] Preferably, a collection frame is fixedly connected to the outer wall of the base on the side away from the conveying roller group, a guide plate is slidably connected to the inner wall of the collection frame, an expansion frame is fixedly connected to the outer wall of the guide plate, and the outer wall of the expansion frame is in contact with the outer wall of the collection frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5This utility model provides a technical solution: a fixed-length cutting structure for preparing composite fiber web, comprising: a base 1, a conveying roller group 2 fixedly connected to the outer wall of the top of the base 1, and a cutting device 3, the outer wall of the bottom of the cutting device 3 being fixedly connected to the outer wall of the top of the base 1; the cutting device 3 includes a cutting seat 31, the outer wall of the top of the cutting seat 31 having a cutting groove 32 and a slanted groove 33, a sensor 34 symmetrically fixedly connected to the outer wall of the top of the cutting seat 31, a support plate 35 symmetrically fixedly connected to the outer wall of the top of the cutting seat 31, a hydraulic rod 36 fixedly connected to the outer wall of the top of the support plate 35, an installation block 37 fixedly connected to the outer wall of the bottom of the hydraulic rod 36, bolts 38 symmetrically threadedly connected to the inner wall of the installation block 37, an installation groove 39 opening on the outer wall of the installation block 37, a gate 391 slidably connected to the inner wall of the installation groove 39, and positioning holes 392 symmetrically opening on the outer wall of the gate 39.

[0027] The outer wall of the bottom of the cutting seat 31 is fixedly connected to the outer wall of the top of the base 1. The outer wall of the side of the sensor 34 is fixedly connected to the outer wall of the side of the support plate 35. The sensor 34 is set at both ends of the cutting seat 31. The sensor 34 adopts the commercially available BGS-ZL30N / P type sensor. The sensor 34 has a transmitting lens and a receiving lens inside. In the direction of light emission, the angle at which the light reflected by the target object at different positions hits the receiving lens is different. The receiving lens is a focusing lens, which will focus the light reflected back from the same position onto a certain point on the receiving chip. The position of the focal point on the chip reflects the position information of the measured object. The chip converts the position information into an electrical signal and sends it to the processor. When the set distance is reached, a signal is sent to perform the cutting operation. The outer wall of the guillotine 391 is slidably connected to the inner wall of the cutting groove 32.

[0028] The outer wall of the bottom of the telescopic rod on the hydraulic rod 36 is fixedly connected to the outer wall of the top of the mounting block 37. The outer wall of the mounting block 37 is slidably connected to the inner wall of the support plate 35. The inner wall of the positioning hole 392 is slidably connected to the outer wall of the bolt 38. When the hydraulic rod 36 is activated, its telescopic rod extends downward, causing the mounting block 37 at the bottom to slide downward along the inner wall of the support plate 35. The gate 391 on the mounting block 37 then moves downward along the inner wall of the cutting groove 32 to cut the fiber web.

[0029] A horizontal plate 393 is fixedly connected to the outer wall of the mounting block 37. A slide rod 394 is slidably connected to the inner wall of the horizontal plate 393. A pressure plate 395 is fixedly connected to the outer wall at the bottom of the slide rod 394. A compression spring 396 is fixedly connected to the outer wall at the top of the pressure plate 395. An anti-detachment plate 397 is fixedly connected to the outer wall at the top of the slide rod 394.

[0030] The outer wall of the compression spring 396 on the side away from the pressure plate 395 is fixedly connected to the outer wall of the bottom of the horizontal plate 393. The outer wall of the bottom of the pressure plate 395 is in contact with the outer wall of the top of the cutting seat 31. During the cutting process of the guillotine 391 pressing down, the pressure plate 395 at the bottom of the slide rod 394 on the horizontal plate 393 on the outer wall of the mounting block 37 first contacts the fiber web. As the guillotine 391 continues to press down, the compression spring 396 is compressed, and the pressure plate 395 presses the fiber web tightly onto the cutting seat 31 to prevent the fiber web from moving during cutting and to ensure the accuracy of cutting.

[0031] A collection frame 4 is fixedly connected to the outer wall of the base 1 on the side away from the conveyor roller group 2. A guide plate 5 is slidably connected to the inner wall of the collection frame 4. An extension frame 6 is fixedly connected to the outer wall of the guide plate 5, and the outer wall of the extension frame 6 is in contact with the outer wall of the collection frame 4. The collection frame 4 can be extended and retracted through the guide plate 5 on the extension frame 6 to adjust the size of the collection frame 4.

[0032] In use, the conveying roller group 2 at the top of the base 1 is responsible for conveying the composite material fiber web and moving it toward the cutting device 3. The cutting device 3 causes the cut fiber web to fall into the collection frame 4 on the side of the base 1 away from the conveying roller group 2.

[0033] The BGS-ZL30N / P type sensors installed at both ends of the top of the cutting seat 31 work based on the principle of triangulation using their internal transmitting and receiving lenses. The transmitting lens emits laser light, which is reflected at different positions on the fiber web. The angle at which the light hits the receiving lens is different. The receiving lens focuses the light reflected from the same position onto the corresponding point on the receiving chip. The chip obtains position information based on the position of the focal point and converts it into an electrical signal for the processor. When the sensor 34 detects that the fiber web has moved to a set fixed distance, it sends a signal. After the signal is triggered, the conveyor roller group 2 stops, the hydraulic rod 36 at the top of the support plate 35 moves, and its telescopic rod extends downward, driving the mounting block 37 at the bottom to slide down along the inner wall of the support plate 35. The guillotine 391 on the mounting block 37 then moves down along the inner wall of the cutting groove 32 to cut the fiber web.

[0034] During the cutting process of the guillotine 391 pressing down, the pressure plate 395 at the bottom of the slide rod 394 on the horizontal plate 393 on the outer wall of the mounting block 37 first contacts the fiber web. As the guillotine 391 continues to press down, the compression spring 396 is compressed, and the pressure plate 395 presses the fiber web tightly onto the cutting seat 31 to prevent the fiber web from moving during cutting and to ensure the accuracy of cutting. The anti-detachment plate 397 can limit the slide rod 394.

[0035] After cutting, the hydraulic rod 36 retracts, driving the gate 391 and mounting block 37 and other components to rise and reset. The cut fiber web falls through the inclined groove 33 into the collection frame 4 on the side of the base 1 away from the conveyor roller group 2. The collection frame 4 can be extended and retracted through the guide plate 5 on the extension frame 6 to adjust the size of the collection frame 4.

[0036] When the switch 391 needs to be replaced or maintained, unscrew the symmetrical bolts 38 on the mounting block 37. Since the inner wall of the positioning hole 392 is slidably connected to the outer wall of the bolt 38, after the bolt 38 is unscrewed, the switch 391 can be removed from the mounting groove 39 to complete the disassembly. The reverse is also true.
