Description

Technical Field

[0001] This invention relates to the field of fiber cutting machine technology, and more specifically to a fiber cutting machine that cuts fibers horizontally and vertically without any excess material. Background Technology

[0002] Fiber materials are common raw materials. For example, in composite materials, fiber materials are often added to achieve or enhance the performance of the composite material. Fibers used as raw materials are usually in the form of long fibers, such as fiber bundles, or produced, processed, transported, and stored as fine threads. When used as a raw material, long fibers must usually be cut into short fibers. For example, LFT, or long fiber reinforced thermoplastic, refers to fibers used in contrast to those used in ordinary fiber reinforced thermoplastic. Typically, the fiber length in fiber reinforced thermoplastic is less than 1 mm, while in LFT, the fiber length is generally greater than 2 mm, and can even be maintained above 5 mm.

[0003] Existing cutting machines can only cut fiber materials in one direction during use. However, the fiber materials are often piled up haphazardly on the tray during operation, resulting in most of the fiber materials not being effectively cut.

[0004] Therefore, how to provide a fiber cutting machine that can cut randomly stacked fiber materials in multiple directions without any excess material in both the horizontal and vertical directions is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a fiber cutting machine with no excess material in both horizontal and vertical directions, which aims to solve the problems in the background art mentioned above and realize the cutting of randomly stacked fiber materials in multiple directions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fiber cutting machine with no excess material in both horizontal and vertical directions, comprising: Mounting plate, on which a first motor is fixedly connected; Mounting box, the mounting box being mounted on the mounting plate; A guide slide plate is mounted on the mounting plate and extends laterally through the bottom of the mounting box.

A switch, the top of which is rotatably connected to the two upper swing arms, the switch being disposed above the guide slide plate; A push rod is hinged to one side of the guillotine, and a crank wheel is hinged to the end of the push rod away from the guillotine. The crank wheel is connected to the first motor for transmission.

[0007] Furthermore, a push plate is provided on the top of the switch, a lifting plate is provided on the top of the push plate, vertical sliding rods are provided at both ends of the lifting plate, a vertical sliding seat is provided on the inner wall of the mounting box, the vertical sliding seat is vertically penetrating the vertical sliding seat and slidably connected to the vertical sliding seat, and a pressure plate is connected to the bottom of the two vertical sliding rods, the pressure plate abutting against the sliding pad.

[0008] Furthermore, a wheel hole is vertically provided through the lifting plate, and a roller is rotatably connected in the wheel hole, and the roller rolls on the push plate.

[0009] Furthermore, a spring is fitted onto the vertical sliding rod, with one end of the spring abutting against the bottom of the vertical sliding seat and the other end of the spring abutting against the pressure plate.

[0010] Furthermore, the bottom of the pressure plate is provided with pressure teeth.

[0011] Furthermore, the gate includes a gate plate, a blade, a first mounting shaft, and a second mounting shaft. Two first mounting shafts are provided and are both located on the top of the gate plate. The two upper swing arms are rotatably connected to the two first mounting shafts respectively. The second mounting shaft is located on one side of the gate plate and passes through the gate plate. The push rod is rotatably connected to the second mounting shaft. A blade groove is provided at the bottom of the gate plate, and the blade is located in the blade groove. The blade is detachably connected to the gate plate.

[0012] Furthermore, the guide slide plate includes a base plate, side plates, and a pusher plate.

[0013] Furthermore, a sliding groove is provided on the base plate along its length, a sliding block is slidably disposed in the sliding groove, an internal threaded sleeve is provided at the bottom of the sliding block, a threaded rod is provided at the bottom of the base plate, the threaded rod cooperates with the internal threaded sleeve, a second motor is provided at the bottom of the base plate, and the threaded rod is connected to the second motor for transmission.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a fiber cutting machine with no excess material in both horizontal and vertical directions. By setting a guide slide plate to pass through the mounting box horizontally, and setting a sliding pad on the guide slide plate, in use, the sliding pad plate moves the stacked fiber material to below the gate. The gate cuts the fiber material on the sliding pad plate. After the gate completes the first cut of the fiber material, the sliding pad plate removes the fiber material. Then, by manually rotating the sliding pad plate, the sliding pad plate and the fiber material on the sliding pad plate are rotated 90°. Then, the sliding pad plate slides in the opposite direction along the guide slide plate, and the gate cuts the fiber material on the sliding pad plate again after rotating 90°. This can realize the horizontal and vertical cutting of fiber material, and achieve the cutting of messy stacked fiber material in multiple directions, thereby achieving efficient cutting of fiber material.

The two boxes are parallel to each other, and the two ends of fixed shaft 6 are rotatably connected to the two boxes respectively.

[0021] The guide slide plate 4 is mounted on the mounting plate 1 and extends laterally through the bottom of the mounting box 3. A sliding pad 5 is slidably connected to the guide slide plate 4. In this embodiment, the length direction of the guide slide plate 4 is perpendicular to the length direction of the mounting box 3, and the guide slide plate 4 allows the sliding pad 5 to slide in a direction perpendicular to the gate 8.

[0022] Fixed shaft 6 is installed inside the mounting box 3. There are two fixed shafts 6, which are parallel to the guide slide plate 4. In this embodiment, the two fixed shafts 6 are at the same height and have a large gap between them. One end of each of the two upper swing arms 7 is connected to the fixed shaft 6 through bearings.

[0023] There are two upper swing arms 7, which are respectively hinged to the fixed shaft 6. The two upper swing arms 7 are parallel to each other and swing synchronously. In this embodiment, the upper swing arm 7 includes two swing plates with round holes at both ends. The two swing plates are respectively arranged on both sides of the gate 8, which can pull the gate 8 on both sides to prevent the gate 8 from shaking and deviating.

[0024] A gate 8 is rotatably connected at its top to two upper swing arms 7 and is positioned above the guide slide plate 4. The gate 8 includes a gate plate 81, a blade 82, a first mounting shaft 83, and a second mounting shaft 84. Two first mounting shafts 83 are provided, each positioned at the top of the gate plate 81. The two upper swing arms 7 are rotatably connected to the two first mounting shafts 83 respectively. The second mounting shaft 84 is located on one side of the gate plate 81 and passes through it. A push rod 9 is rotatably connected to the second mounting shaft 84. A blade groove is provided at the bottom of the gate plate 81. The blade 82 is set in the blade groove and is detachably connected to the gate plate 81. In this embodiment, the blade 82 is fixedly installed in the blade groove by a set bolt. When the blade 82 needs to be replaced due to wear or chipping defects during long-term use, the old blade 82 can be taken out of the blade groove simply by loosening the set bolt, and the new blade 82 can be installed and the set bolt tightened again to complete the replacement. There is no need to replace the entire gate plate 8 component, which effectively reduces the later maintenance cost of the equipment and simplifies the maintenance operation process.

[0025] Push rod 9 is hinged to one side of the gate 8. A crank wheel 10 is hinged to the end of push rod 9 away from the gate 8. The crank wheel 10 is connected to the first motor 2 for transmission. In this embodiment, push rod 9 is equivalent to the connecting rod in the crank-slider mechanism, and crank wheel 10 is equivalent to the crank in the crank-slider mechanism. A shaft for push rod 9 to hinge is provided on the outer wall of crank wheel 10. The shaft of crank wheel 10 and the axis of the shaft are not on the same axis. The axis of crank wheel 10 and the axis of the shaft are parallel to each other. Gate plate 81 is equivalent to the slider in the crank-slider mechanism. Push rod 9 pushes gate plate 81 to reciprocate in the inclined direction.

[0026] A push plate 11 is provided on the top of the guillotine 8, and a lifting plate 12 is provided on the top of the push plate 11. Vertical sliding rods 13 are provided at both ends of the lifting plate 12. A vertical sliding seat 14 is provided on the inner wall of the mounting box 3. The vertical sliding seat 14 is vertically penetrated and slidably connected to the vertical sliding seat 14. A pressure plate 15 is connected to the bottom of the two vertical sliding rods 13, and the pressure plate 15 abuts against the sliding pad 5. In this embodiment, during the cutting operation, the first motor 2 outputs torque to drive the crank wheel 10 to rotate. The crank wheel 10 pushes the guillotine 8 downward to perform a cutting feed action through the push rod 9. The push plate 11 moves down synchronously with the guillotine 8. At this time, the spring 1 8. Release the pre-tightening force to push the vertical slide rod 13 downward along the vertical slide seat 14, which in turn drives the pressure plate 15 to move downward. It contacts the fiber material stacked on the sliding pad 5 before the blade 82, pressing and fixing the fiber material to the surface of the sliding pad 5. The pressure teeth 19 set at the bottom of the pressure plate 15 can increase the friction between the pressure plate 15 and the fiber material, further improving the reliability of the pressing and fixing. It can effectively prevent the fiber material from shifting or moving during the cutting process, ensuring the cutting accuracy of the blade 82, and avoiding the problem of some fibers not being cut off and residual material due to material shifting. This meets the design goal of the present invention of cutting without residual material.

[0027] A wheel hole 16 is vertically through the lifting plate 12, and a roller 17 is rotatably connected in the wheel hole 16. The roller 17 rolls on the push plate 11. A spring 18 is sleeved on the vertical slide rod 13. One end of the spring 18 abuts against the bottom of the vertical slide seat 14, and the other end of the spring 18 abuts against the pressure plate 15. The bottom of the pressure plate 15 is provided with pressure teeth 19. In this embodiment, after the gate 8 completes a cutting operation, the gate 8 moves upward at an angle away from the push rod 9. The push plate 11 moves upward at an angle in sync with the gate 8. The push plate 11 can push the roller 17 to move upward. The roller 17 also rolls on the push plate 11, thereby enabling the lifting plate 12 to move laterally when it is pushed upward.

[0028] The guide slide plate 4 includes a base plate 41, side plates 42, and a pusher plate 43. The bottom of the base plate 41 is connected to the mounting plate 1. The side plates 42 are arranged on both sides of the base plate 41 along its length. The pusher plate 43 slides on the base plate 41 on the side plates 42. A groove is provided on the base plate 41 along its length. A sliding block 20 is slidably arranged in the groove. An internal threaded sleeve 21 is provided at the bottom of the sliding block 20. A threaded rod 22 is provided at the bottom of the base plate 41. The threaded rod 22 cooperates with the internal threaded sleeve 21. A second motor 23 is provided at the bottom of the base plate 41. The threaded rod 22 is connected to the second motor 23 for transmission. In this example, when the fiber material needs to be cut in another direction, simply move the sliding pad 5 out of the mounting box 3 along the guide slide plate 4, manually rotate the sliding pad 5 90°, and then put it back into the mounting box 3 along the guide slide plate 4. This changes the extension direction of the fiber material relative to the blade edge of the guillotine 8. The equipment can then be started to complete the cutting operation in the other direction. The entire operation is simple and requires no adjustment to the equipment structure. It can achieve cutting operations in both horizontal and vertical directions, effectively adapting to the cutting needs of randomly stacked fiber materials, ensuring that all fibers are effectively cut, and ultimately achieving a zero-residue cutting effect. During operation, the second motor 23 drives the threaded rod 22 to rotate. Through the cooperation of the internal threaded sleeve 21 and the threaded rod 22, the sliding block 20 moves along the slide groove, which in turn drives the pusher plate 43 to push the sliding pad 5 along the guide slide plate 4, automatically completing the feeding operation. This further improves the automation level of the cutting process and reduces the intensity of manual operation.
