Description

Technical Field

[0001] This utility model relates to the field of carbon material processing technology, specifically to a carbon fiber prepreg positioning and cutting device. Background Technology

[0002] Cutting is a crucial step in the prepreg production process. Currently, the industry standard is to use a wheeled cutter, which cuts the prepreg by moving it in a straight line. However, this method requires the cutter to rotate while moving laterally, necessitating two motors to control both the lateral movement and rotation of the cutter in tandem. This dual-motor drive mode has several drawbacks. From an economic perspective, adding an extra motor significantly increases the equipment's purchase cost and, over long-term use, leads to increased energy consumption and higher operating costs. In terms of efficiency, the coordinated operation of the two motors requires a complex control system to ensure synchronized operation. Any misalignment can result in decreased cutting accuracy or even cutting interruptions, severely impacting production schedules. Furthermore, the two motors and their associated systems complicate the equipment structure, increasing the difficulty and cost of daily maintenance and troubleshooting. Summary of the Invention

[0003] The purpose of this invention is to provide a single-motor driven, compact carbon fiber prepreg positioning and cutting device.

[0004] To achieve the above-mentioned invention objectives, the technical solution adopted by this utility model is: a carbon fiber prepreg positioning and cutting device, including a worktable, an installation cavity is provided inside the worktable, and a cutting hole extending along the width direction of the worktable is provided on the worktable surface.

[0005] The mounting cavity is equipped with a blade holder and a drive bar. The blade holder can move laterally along the worktable under the drive of the drive mechanism. The blade holder is equipped with a wheel-type cutter that rotates with the blade holder. The wheel-type cutter is positioned opposite the cutting hole, and the upper part of the wheel-type cutter passes through the cutting hole. The drive bar is located on one side of the blade holder and extends along the width direction of the worktable. The axle of the wheel-type cutter extends above the drive bar and is equipped with a friction drive wheel that cooperates with the drive bar.

[0006] Preferably, one section of the axle is a rubber vibration-damping section.

[0007] Preferably, the cutter holder includes a base and a support frame disposed above the base, and the wheel cutter is mounted on the support frame; the base moves laterally along the worktable under the drive of the drive mechanism.

[0008] Preferably, the drive mechanism includes a lead screw and a guide rod extending laterally along the worktable and passing through the base body. The lead screw is threadedly engaged with the base body, and one end of the lead screw is connected to the prime mover. The guide rod is slidably engaged with the base body.

[0009] The beneficial effects of this invention are mainly reflected in its ability to synchronously control the rotation and lateral movement of the wheel cutter through a single prime mover, resulting in a simple and compact structure and low maintenance costs. Specifically, during use, the prepreg workpiece is positioned on top of the worktable (positioned with the aid of adjustable pressure bars, etc.). The cutter holder moves under the drive mechanism, causing it to move laterally along the worktable (in the width direction of the prepreg). As the cutter holder continues to move, the friction drive wheel cooperates with the drive bar to rotate the axle, which in turn drives the wheel cutter to rotate, thus achieving cutting of the workpiece during the lateral movement. Because this invention can achieve both lateral and rotational drive with only one prime mover (motor), the overall structure is simpler and maintenance costs are lower. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0011] like Figure 1 As shown in the figure, a carbon fiber prepreg positioning and cutting device is used to cut prepreg. It includes a worktable 1, an installation cavity 2 is provided inside the worktable 1, and a cutting hole 3 extending along the width direction of the worktable 1 is provided on the table surface of the worktable 1, as shown in the figure. The width direction or transverse direction is the front-back direction in the figure.

[0012] The mounting cavity 2 is equipped with a blade holder 4 and a drive bar 5. The blade holder 4 is used to mount the wheel-type cutter 6. Generally, the blade holder 4 includes a base and a support frame mounted on the base, with the wheel-type cutter mounted on the support frame. The blade holder 4 can move laterally along the worktable 1 under the drive of the drive mechanism. In the above structure, the base moves laterally along the worktable 1 under the drive of the drive mechanism. The drive mechanism can be a linear cylinder, a linear electric actuator, etc., or as shown in the figure, the drive mechanism includes a lead screw 10 and a guide rod 11 extending laterally along the worktable 1 through the base. The lead screw 10 is threadedly engaged with the base, and one end of the lead screw 10 is connected to the prime mover (i.e., a motor). The guide rod 11 is slidably engaged with the base.

[0013] The present invention describes a tool holder 4 equipped with a wheel-type cutter 6 that rotates with the tool holder 4. The wheel-type cutter 6 is positioned opposite the cutting hole 3, and its upper part passes through the cutting hole 3. The wheel-type cutter 6 rotates along the cutting hole 3 to cut the material. The drive bar 5 is located on one side of the tool holder 4 and extends along the width of the worktable 1, and is used to drive the wheel-type cutter 6 to rotate. The axle 7 of the wheel-type cutter 6 extends above the drive bar 5 and is equipped with a friction drive wheel 8 that cooperates with the drive bar 5. The friction drive wheel 8 is driven to rotate through contact with the drive bar 5.

[0014] During use, the prepreg workpiece is positioned on top of the workbench 1 (with auxiliary positioning via adjustable pressure bars, etc.). The cutter holder 4 moves under the drive of the drive mechanism, causing it to move laterally along the workbench 1 (in the direction of the prepreg width). As the cutter holder 4 continues to move, the friction drive wheel 8 cooperates with the drive bar 5 to drive the axle 7 to rotate, which in turn drives the wheel cutter 6 to rotate, thus achieving cutting of the workpiece during the lateral movement. Since this invention can achieve both lateral and rotary drive with only one prime mover (motor), the overall structure is simpler and the maintenance cost is lower.

[0015] Since the friction drive wheel 8 and drive bar 5 will vibrate during the friction drive process, in order to prevent the vibration from being transmitted to the wheel cutter 6, a better approach of this utility model is to make a section of the wheel axle 7 a rubber vibration filtering section 9, so as to buffer and eliminate the vibration through the vibration filtering section 9, thereby ensuring the stability of the wheel cutter 6 and improving the cutting quality.
