Description

Technical Field

[0001] The utility model relates to the technical field of fiber cutting machine tool holders, in particular to a numerically controlled fiber cutting machine tool holder device. Background Art

[0002] The blade holder assembly of a CNC fiber cutter is a key component of the machine, responsible for achieving high-speed and precise cutting of fiber materials. The blades can be either rotating or fixed, and the material is delivered to the cutting edge via a conveyor belt. The relative motion between the rotating and fixed blades completes the cut. The blade holder assembly allows for adjustable blade spacing to accommodate varying cutting lengths. It is the core of automated, precise cutting, and its performance directly impacts cutting efficiency and quality.

[0003] However, in practice, due to the lack of fiber-holding devices at both ends of the blade holder, the fiber material may shift or vibrate during the cutting process, resulting in inaccurate cutting positions and affecting cutting accuracy. This not only affects product quality but also increases the difficulty of subsequent processing. Fiber material easily bends and folds during the cutting process, affecting cutting speed. The lack of a close fit with the blade increases cutting resistance and reduces efficiency. The increased friction between the blade and the fiber causes accelerated blade wear, increasing maintenance costs and potentially affecting cutting results.

[0004] In addition, the shaking and folding of the fiber material during the cutting process may cause fiber fragments to fly, posing a safety hazard to operators. Utility Model Content

[0005] The main purpose of the utility model is to provide a tool holder device for a numerically controlled fiber cutting machine, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A tool holder device for a numerically controlled fiber cutting machine comprises a support frame, a hydraulic cylinder, and a stabilizing rod, wherein the hydraulic cylinder is installed in the middle section of the support frame, and two stabilizing rods are connected to both ends of the support frame;

[0008] The telescopic end of the hydraulic cylinder is connected to a connecting knife holder, and a cutting knife is installed on the connecting knife holder through a bolt. The stabilizing rod is connected to the connecting knife holder, and the connecting knife holder and the cutting knife are moved up and down by the hydraulic cylinder and the stabilizing rod, and the fiber object is cut by the cutting knife.

[0009] A mounting frame is installed on the upper end of the connecting knife holder, and waist holes are opened at both ends of the mounting frame. A connecting rod is inserted into each waist hole, and the lower ends of the two connecting rods are connected to tightening strips. The connecting knife holder is driven by a hydraulic cylinder and the tightening strips are driven to press against the two ends of the fiber object, which facilitates the cutting tool to realize the cutting operation.

[0010] As a further preferred embodiment of the present application, a docking knife seat adapted to the cutting knife is provided inside the support frame, and a feed rack is installed at the rear end of the docking knife seat, and a conveyor belt is installed on the feed rack, and a discharge rack is installed at the front end of the docking knife seat, and the fiber objects are transmitted by the conveyor belt and discharged from the discharge rack after being cut by the cutting knife;

[0011] As a further preferred embodiment of the present invention, the two pressing bars are aligned with the feed rack and the discharge rack and driven by a hydraulic cylinder to press against the rack body, and the lower ends of the pressing bars are designed to be arc-shaped;

[0012] As a further preferred embodiment of the present invention, the connecting rod and the abutting strip are perpendicular to each other and are integrally designed. The connecting rod is a screw rod, which passes through a waist hole and is sleeved with a plurality of nuts and anti-slip washers, and is fixed to the mounting frame by the nuts and anti-slip washers.

[0017] The lower end of the abutment bar is designed to be curved, which can adapt to fiber objects of different shapes and sizes, increasing the applicability of the device. The abutment bar can quickly and firmly press against the ends of the fiber object, allowing the cutting tool to cut quickly, thereby improving the efficiency of the entire cutting process.

[0018] The lower end of the abutment strip is bonded with a non-slip rubber strip, increasing friction with the fiber material, ensuring a secure hold and preventing it from slipping during the cutting process. The lower end of the abutment strip is beveled to better adapt to the shape of the fiber material, optimizing the cutting process and minimizing damage.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0026] like Figures 1 to 4 As shown, this embodiment illustrates a tool holder assembly for a CNC fiber cutting machine. Its main components include a support frame 1, a hydraulic cylinder 2, and stabilizer bars 3. The hydraulic cylinder 2 is mounted in the middle of the support frame 1, while two stabilizer bars 3 are connected to each end of the support frame 1. The telescopic end of the hydraulic cylinder 2 is connected to a connecting tool holder 4, to which a cutting tool 5 is bolted. The stabilizer bars 3 are connected to the connecting tool holder 4. The hydraulic cylinder 2 and stabilizer bars 3 work together to achieve the vertical movement of the connecting tool holder 4 and the cutting tool 5, thereby using the cutting tool 5 to cut the fiber material.

[0027] Mounting bracket 6 is mounted on the upper end of connecting blade holder 4, with two ends of mounting bracket 6 having waist holes 7. Connecting rods 8 are inserted into and connected to each waist hole 7. The lower ends of the two connecting rods 8 are connected to retaining bars 9. Driven by hydraulic cylinder 2, connecting blade holder 4 and retaining bars 9 operate together, pressing against the ends of the fiber object, facilitating the cutting operation of cutting blade 5.

[0028] Two abutment bars 9 are aligned with the feed frame 11 and the discharge frame 13, respectively, and are driven by hydraulic cylinder 2 to abut against the frames. The lower end of the abutment bars 9 is designed to be curved to accommodate fibrous objects of varying shapes. The connecting rod 8 is perpendicular to the abutment bars 9 and is an integrated design. The connecting rod 8 is a threaded rod that passes through the waist hole 7 and is fitted with multiple nuts and anti-slip washers. These nuts and anti-slip washers secure the connecting rod 8 to the mounting frame 6.

[0029] The mounting bracket 6 is mounted on the telescopic end of the hydraulic cylinder 2 and bolted to the connecting tool holder 4. The lower end of the clamping bar 9 is bonded with a non-slip rubber strip to increase friction and ensure the clamping effect. The lower end surface of the clamping bar 9 is designed to be inclined to better adapt to the shape of the fiber object. Example

[0030] This embodiment also demonstrates a tool holder assembly for a CNC fiber cutting machine. Its structure is similar to that of the first embodiment, comprising a support frame 1, a hydraulic cylinder 2, and stabilizer bars 3. The hydraulic cylinder 2 is mounted in the middle of the support frame 1, with two stabilizer bars 3 connected to each end of the support frame 1. The telescopic end of the hydraulic cylinder 2 is connected to a connecting tool holder 4, to which a cutting tool 5 is bolted. The stabilizer bars 3 are connected to the connecting tool holder 4. The coordinated action of the hydraulic cylinder 2 and stabilizer bars 3 enables the connecting tool holder 4 and the cutting tool 5 to move up and down, thereby enabling the cutting tool 5 to cut the fiber material.

[0031] Mounting bracket 6 is mounted on the upper end of connecting blade holder 4, with two ends of mounting bracket 6 having waist holes 7. Connecting rods 8 are inserted into and connected to each waist hole 7. The lower ends of the two connecting rods 8 are connected to retaining bars 9. Driven by hydraulic cylinder 2, connecting blade holder 4 and retaining bars 9 operate together, pressing against the ends of the fiber object, facilitating the cutting operation of cutting blade 5.

[0032] Two abutment bars 9 are aligned with the feed frame 11 and the discharge frame 13, respectively, and are driven by hydraulic cylinder 2 to abut against the frames. The lower end of the abutment bars 9 is designed to be curved to accommodate fibrous objects of varying shapes. The connecting rod 8 is perpendicular to the abutment bars 9 and is an integrated design. The connecting rod 8 is a threaded rod that passes through the waist hole 7 and is fitted with multiple nuts and anti-slip washers. These nuts and anti-slip washers secure the connecting rod 8 to the mounting frame 6.

[0033] The mounting bracket 6 is mounted on the telescopic end of the hydraulic cylinder 2 and bolted to the connecting tool holder 4. The lower end of the clamping bar 9 is bonded with a non-slip rubber strip to increase friction and ensure the clamping effect. The lower end surface of the clamping bar 9 is designed to be inclined to better adapt to the shape of the fiber object.

[0034] Furthermore, support frame 1 houses a butt-jointing blade holder 10 compatible with cutting blade 5. A feed frame 11 is mounted at the rear end of butt-jointing blade holder 10, on which a conveyor belt 12 is mounted for transporting fiber objects. A discharge frame 13 is mounted at the front end of butt-jointing blade holder 10. The fiber objects are transported via conveyor belt 12 and discharged from discharge frame 13 after being cut by cutting blade 5.

[0035] Instructions for Use: Activate hydraulic cylinder 2, causing it to push the connecting blade holder 4 downward. At this point, the stabilizing rod 3 works in conjunction with the connecting blade holder 4 to maintain its stability. As the connecting blade holder 4 descends, the abutment bar 9 also descends. Since the abutment bar 9 is aligned with the feed frame 11 and the discharge frame 13, they rest against the frames, thereby securing the fiber material in place. Once the abutment bar 9 securely abuts the fiber material, the cutting tool 5 begins its cutting operation. Driven by the connecting blade holder 4, the cutting tool 5 moves upward, traversing the fiber material and severing it. During the cutting process, the curved lower end of the abutment bar 9 accommodates fiber materials of varying shapes, ensuring optimal cutting performance. After cutting is complete, the hydraulic cylinder 2 reverses its motion, causing the connecting blade holder 4 and the abutment bar 9 to ascend together, clearing the fiber material. As the connecting blade holder 4 ascends, the stabilizing rod 3 continues to stabilize the blade holder, ensuring a smooth ascent. When the connecting blade holder 4 reaches a certain position, the cutting tool 5 separates from the docking blade holder 10, and the fiber material is discharged from the discharge frame 13. After the entire cutting process is completed, the hydraulic cylinder 2 is readjusted to its initial position, ready for the next cutting operation. The connecting rod 8, mounting bracket 6, waist hole 7, and other components work together to ensure the coordinated movement of the connecting blade holder 4 and the abutment bar 9. Furthermore, the anti-slip rubber strip and bevel design allow the abutment bar 9 to better adapt to the shape of the fiber object, improving the cutting effect.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the electric fusion connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0037] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
