Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting technology, and in particular to a double-blade carriage mechanism. Background Technology
[0002] In eccentric cutting devices, especially those used for cutting flexible materials such as films and composite films, the sliding damping of the cutting tool and the cutting pressure are crucial factors directly affecting the cutting quality. However, most existing devices have relatively simple adjustment structures, generally employing mechanical clamping or spring preload for adjustment. While this method is cost-effective, it is prone to insufficient adjustment precision in practical applications.
[0003] First, existing clamping or pre-tightening mechanisms mostly rely on tightening or loosening fasteners to change the clamping force. The adjustment process depends entirely on the operator's feel and experience, lacking precise guiding and positioning structures. This results in large adjustment ranges each time, making it impossible to achieve fine control within a small range and accurately adapt to the cutting needs of film materials with different thicknesses, hardnesses, and surface properties. Second, thin film materials are extremely sensitive to tool pressure and sliding damping. Excessive pressure can easily cause film deformation, wrinkling, or tearing of the cut; insufficient pressure can easily lead to burrs, stringing, or incomplete cuts. Existing coarse adjustment structures cannot find the optimal balance between these two factors, resulting in reduced yield and increased rework rate.
[0004] Therefore, a double-blade car mechanism is proposed to solve the above problems. Utility Model Content

[0045] Reference Figures 1 to 6 The present invention relates to a double-blade courier mechanism, characterized in that it comprises:
[0046] Install the main body 100;
[0047] The cutting assembly 200 is connected to the mounting body 100 and is used to cut the workpiece;
[0048] A drive component 500 is disposed on the mounting body 100 and connected to the cutting component 200, and is used to drive the cutting component 200 to move;
[0049] An adjustment assembly is connected to the cutting assembly 200. The adjustment assembly includes a pin 600 and an adjustment plate assembly 700, the adjustment plate assembly 700 clamping the pin 600.
[0050] When the adjusting plate assembly 700 is slid horizontally, the adjusting plate assembly 700 clamps / releases the pin 600.
[0051] This invention aims to solve the problems of poor tool movement stability, insufficient cutting accuracy, and inflexible adjustment in existing eccentric cutting devices during the processing of thin materials such as films. To address these issues, an adjustment component is installed between the mounting body 100 and the cutting assembly 200. Within this component, a mating structure is introduced between a pin 600 and an adjustment plate assembly 700. This allows the operator to control the clamping or loosening of the pin 600 via the adjustment plate assembly 700, thereby altering the smoothness of the sliding and the damping of the cutting assembly 200, achieving precise adjustment of the cutting state. This solution not only simplifies the structural layout but also improves the adaptability of the device to different working conditions and the cutting quality. Furthermore, it achieves a compact dual-blade carriage structure with a small overall size, making it suitable for integrated applications in miniaturized film cutting equipment.
[0052] This device includes a mounting body 100, a cutting assembly 200, a drive assembly 500, and an adjustment assembly. The drive assembly 500 is fixed to the mounting body 100 and connected to the cutting assembly 200. Under the action of the drive assembly 500, the cutting assembly 200 reciprocates along a preset direction to cut the workpiece. The adjustment assembly is connected to the cutting assembly 200, and the adjustment plate assembly 700 therein clamps the pin 600. When the adjustment plate assembly 700 slides horizontally, its clamping state changes. In the clamped state, the fixation of the pin 600 is increased, the sliding damping of the cutting assembly 200 increases, and the movement is more stable. In the released state, the damping decreases, and the sliding of the cutting assembly 200 is smoother. By finely sliding the adjustment plate assembly 700 at different positions, the clamping force of the pin 600 can be continuously controlled, thereby achieving micro-adjustment of cutting pressure, damping, and sliding performance to adapt to the cutting needs of different film or thin materials. This fine adjustment function allows for continuous and controllable parameter adjustments within a minute range, based on the material, thickness, and tension of different film materials, to achieve optimal film cutting results. Under this fine adjustment, the cutter operates more stably, significantly reducing defects such as burrs, stringing, and chipping during the film cutting process, thus improving cut accuracy and consistency. Simultaneously, the adjustment structure is simple and compact, occupying little space and facilitating integration into miniaturized equipment. Changing the cutter or adjusting the cutting state can be quickly accomplished simply by sliding the adjustment plate assembly 700, minimizing downtime. Furthermore, by preventing over- or under-clamping of the cutter, cutter wear and vibration are effectively reduced, extending cutter life and improving the overall stability and economy of the machine.
[0053] Based on the above embodiments, the adjusting plate assembly 700 includes a mounting plate 710 and an adjusting unit 720. The mounting plate 710 is connected to the mounting body 100. The mounting plate 710 has a sliding groove 730. The adjusting unit 720 is connected to the sliding groove 730 through an adjusting screw 740. The adjusting screw 740 slides along the sliding groove 730 so that the adjusting unit 720 clamps / releases the pin 600.
[0054] In the adjustment assembly of the dual-head carriage mechanism, to further improve the adjustment accuracy and stability of the clamping force on the pin 600, this embodiment introduces a mating structure between the mounting plate 710 and the adjustment unit 720 in the adjustment plate assembly 700. The mounting plate 710 is fixed to the mounting body 100 and is provided with a slide groove 730 to provide a controllable sliding path for the adjustment unit 720. The adjustment unit 720 engages with the slide groove 730 via an adjusting screw 740. The operator can move the adjusting screw 740 along the direction of the slide groove 730 to precisely change the clamping state of the adjustment unit 720 on the pin 600, thereby achieving continuous and controllable adjustment of the clamping force. This design not only makes the adjustment action more stable and reliable, but also facilitates rapid fine-tuning according to working conditions during production, ensuring the stability of the cutting effect. The mounting plate 710 is fixed to the mounting body 100 by fasteners, and its surface is provided with a slide groove 730 consistent with the preset adjustment direction. The adjustment unit 720 is installed in conjunction with the slide 730 via the adjustment screw 740. The adjustment screw 740 serves both as a guide and as a position lock, thereby improving the accuracy and stability of the clamping force adjustment of the pin 600. Furthermore, the tightness and smoothness of the sliding of the two tool holders 420 can be adjusted by the cross fastening screw and the adjustment plate assembly 700, ensuring the stability of the cutting effect.
[0055] The drive assembly 500 includes an electromagnet 510, two linear bearings 520, and a carriage axle 530. The electromagnet 510 is bolted to the mounting body 100. The two linear bearings 520 are respectively mounted on the mounting body 100 by locking screws. The carriage axle 530 passes through the linear bearings 520. One end of the carriage axle 530 is connected to the electromagnet 510 through a connecting rod 540, and the other end of the carriage axle 530 is connected to the cutting assembly 200.
[0056] When the electromagnet 510 is energized, the linear bearing 520 and the carriage shaft 530 drive the cutting assembly 200 to move along the direction of the workpiece.
[0057] It also includes an elastic element 800. The carriage shaft core 530 is provided with a lower cutter cap 550. The connecting rod 540 is connected to the carriage shaft core 530 through the lower cutter cap 550. The elastic element 800 is disposed between the lower cutter cap 550 and the linear bearing 520. The elastic element 800 is configured to reset the lower cutter clamp 300 after the electromagnet 510 is de-energized.
[0058] The locking screws are arranged in a straight line in the vertical direction.
[0059] This embodiment also includes an electronic control board 900. The drive assembly 500 includes a mating structure of an electromagnet 510, a linear bearing 520, and a carriage shaft 530. The electronic control board 900 is electrically connected to the electromagnet 510. The electromagnet 510 serves as the power source, and the linear bearing 520 provides high-precision linear guidance to the carriage shaft 530, ensuring that the cutting assembly 200 makes smooth linear motion along the workpiece direction. One end of the carriage shaft 530 is connected to the electromagnet 510 via a connecting rod 540, and the other end is connected to the cutting assembly 200, allowing the driving force to be directly transmitted to the cutting assembly 200, achieving efficient and low-vibration linear cutting. This structure aims to reduce sway and vibration during the cutting process, improving film cutting quality and processing efficiency. The electromagnet 510 is bolted to the mounting body 100, and its output end is connected to one end of the carriage shaft 530 via a connecting rod 540. Two linear bearings 520 are mounted on the mounting body 100 in a cross-arranged manner using locking screws, which are arranged in a straight line in the vertical direction to reduce the overall front-to-back width of the carriage mechanism. The carriage shaft 530 passes through the linear bearings 520, which provide high-precision guiding support for the carriage shaft 530, limiting its non-linear movement. When the electromagnet 510 is energized, the driving connecting rod 540 pushes the carriage shaft 530 to move linearly along the workpiece direction, thereby driving the cutting assembly 200 at the other end to cut the film material. When the power is off, the driving force disappears, and the cutting assembly 200 returns to its initial position under the action of the elastic element 800.
[0060] The cutting assembly 200 includes a lower blade clamp 300 and a cutting unit 400. The cutting unit 400 is connected to the lower blade clamp 300, and the lower blade clamp 300 is connected to the sports car axle core 530 and the pin 600.
[0061] When the electromagnet 510 is energized, the carriage shaft core 530 drives the lower blade holder 300 to move along the direction of the workpiece, so that the cutting unit 400 cuts the workpiece.
[0062] The cutting unit 400 includes a fixing block 410 and a tool holder 420. The fixing block 410 is connected to the lower tool clamp 300 and the tool holder 420 is connected to the tool holder 420. The fixing block 410 is configured to fix the tool holder 420. A cutting blade for cutting the workpiece is installed at the lower end of the tool holder 420.
[0063] The lower blade clamp 300 includes a left blade clamp 310 and a right blade clamp 320, which are arranged in a straight line adjacent to each other in the horizontal direction.
[0064] The lower tool holder 300 has a hollow structure.
[0065] In this embodiment, the cutting assembly 200 adopts a separate combination of the lower blade clamp 300 and the cutting unit 400. The lower blade clamp 300 is connected to the drive and adjustment mechanism through the carriage shaft core 530 and the pin shaft 600, respectively, to achieve stable linear drive and controllable clamping force. The cutting unit 400 consists of a fixing block 410 and a blade holder 420. The fixing block 410 reliably fixes the blade holder 420 to the lower blade clamp 300. The cutting blade is installed at the lower end of the blade holder 420 for direct cutting of the film surface. The lower blade clamp 300 adopts a layout with the left and right blade clamps 320 arranged adjacently in a straight line, achieving a compact arrangement of the two blade heads, reducing space occupation and facilitating simultaneous or individual operation. The body of the lower blade clamp 300 is designed as a hollow structure, which reduces the overall weight while ensuring strength, reduces the drive load, and improves response speed and cutting stability.
[0066] When the electromagnet 510 is energized, its driving force is transmitted to the carriage shaft 530 through the connecting rod 540. The carriage shaft 530 moves along the linear bearing 520 and drives the lower blade holder 300 to move smoothly along the workpiece direction. The lower blade holder 300, through an adjustment component that cooperates with the pin 600, can adjust its clamping state and sliding damping as needed, thereby controlling the pressure of the cutting blade on the film material and the smoothness of operation. The fixing block 410 ensures that the blade holder 420 is stable and does not shift, so that the cutting blade maintains a precise blade path during movement to cut the film material. The left and right blade holders 320 are arranged adjacent to each other to achieve simultaneous cutting with two blades, improving cutting efficiency; when single-blade operation is required, only the blade holder 420 corresponding to one blade holder can be driven to work. The hollow structure of the lower blade holder 300 reduces weight, decreases inertia, and improves drive response speed while maintaining structural strength.
[0067] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
