Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to a cutting machine feeding device. Background Technology

[0002] In the field of batch processing of flexible or semi-flexible sheet materials such as fabrics, leather, foam plastics, and paper, the cutting machine feeding device is the core equipment for realizing automated material cutting and improving production efficiency.

[0003] A search revealed a cutting machine feeding device disclosed in Chinese Patent No. CN222038756U. The device mainly consists of a workbench, a conveyor belt, a drive assembly, and a cutting assembly. The conveyor belt is laid on the workbench, and the drive assembly provides power to the conveyor belt to realize continuous material conveying. The cutting assembly is correspondingly set above the conveyor belt to complete the material cutting operation.

[0004] However, the width specifications of materials to be cut vary greatly in industrial production. Existing devices often have fixed or cumbersome limiting structures, which cannot be quickly and accurately adapted to the width of the materials. This causes the materials to easily deviate to the left or right during the conveyor belt transport process. Furthermore, during the cutting process, the materials are subjected to the combined effects of the vertical pressure and horizontal friction of the cutting blade, which can easily cause localized lifting. Some materials may even move upwards as the cutting blade rises due to excessive friction with it. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has shortcomings and defects such as the limiting structure of existing devices being mostly fixed or the adjustment method being cumbersome, and the material being prone to left and right deviation during the conveyor belt transportation process.

[0006] The cutting machine feeding device disclosed in this utility model includes a workbench and a conveyor belt. The conveyor belt is installed on the workbench, and a driving component is provided between the conveyor belt and the workbench. A fixed frame is installed on the upper end of the workbench, and a cutting component is provided on the fixed frame. A horizontal plate is provided on one side of the fixed frame, and sliding plates are slidably installed at both ends of the horizontal plate. An adjustment component is provided between the sliding plates and the horizontal plate. A vertical plate is installed on the side of the two sliding plates that are far apart from each other, and a limit component is installed on the side of the two sliding plates that are close to each other.

[0007] Furthermore, the lower end of the vertical plate contacts the conveyor belt, and a rubber pad is fixedly installed on the side of the two vertical plates that are close to each other.

[0008] Furthermore, the limiting component includes a rotating frame, with a roller mounted on the lower end of the rotating frame, a slide rod rotatably mounted on the upper end of the rotating frame, a fixed cylinder slidably disposed on the upper end of the slide rod, the fixed cylinder being mounted on the slide plate, and a spring being disposed between the slide rod and the fixed cylinder.

[0009] Furthermore, the spring is disposed inside the slide rod, and a pressure plate is disposed above the spring. An adjusting rod is installed at the upper end of the pressure plate, and the adjusting rod is threadedly connected to the fixed cylinder.

[0010] Furthermore, the adjustment assembly includes a bidirectional threaded rod, both ends of which are rotatably mounted on the horizontal plate. Both ends of the bidirectional threaded rod are threadedly connected to the corresponding sliding plate. A drive source is provided between the middle of the bidirectional threaded rod and the horizontal plate, and the drive source is fixedly mounted on the fixed frame.

[0011] Furthermore, the drive assembly includes a drive motor, a drive roller, and a driven roller; the drive roller and the driven roller are rotatably mounted at both ends of the worktable along its length, and the conveyor belt is tensioned and sleeved on the outside of the drive roller and the driven roller; the drive motor is fixed to the worktable by a motor bracket, and its output shaft is connected to the drive roller via a coupling.

[0012] Furthermore, the cutting assembly includes a lifting plate, which is disposed between the conveyor belt and the fixed frame. A cutting blade is installed at the lower end of the lifting plate, and a telescopic cylinder is disposed between the upper end of the lifting plate and the fixed frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a drive source in the adjustment component to drive the bidirectional threaded rod to rotate, which can drive the two slide plates and the vertical plate to move synchronously in opposite directions. This enables rapid and precise adaptation and adjustment of materials to be cut with different widths and specifications, without the need for cumbersome operations. At the same time, the lower end of the vertical plate contacts the conveyor belt and is equipped with a rubber pad on the inner side, which can form a stable limit on both ends of the material, preventing the material from deviating to the left or right during the conveyor belt transport process. This solves the problem that the limit structure of the existing device is fixed or cumbersome to adjust and cannot adapt to multiple specifications of materials, thus improving the stability of material conveying.

[0014] 2. This utility model utilizes the elastic force of the spring in the limiting component to push the slide bar and rotating frame downwards, allowing the rollers to closely adhere to the material surface. When the cutting blade presses down to cut, the rollers effectively suppress localized material lifting, and the rolling characteristics of the rollers reduce frictional resistance with the material, preventing the material from moving upwards with the cutting blade due to excessive friction between it and the blade. This ensures a stable cutting process, guarantees cutting accuracy, and ensures the continuity of subsequent material conveying. Attached Figure Description

The drive roller and the driven roller are rotatably installed at both ends of the workbench 1 in the length direction. The conveyor belt 2 is tensioned and sleeved on the outside of the drive roller and the driven roller. The drive motor is fixed on the workbench 1 by a motor bracket. The drive motor is a three-phase asynchronous motor, and its output shaft is connected to the drive roller through a coupling.

[0019] See Figure 1 , Figure 4 As shown, a fixed frame 3 is installed on the upper end of the workbench 1. A cutting assembly is provided on the fixed frame 3. The cutting assembly includes a lifting plate 4. The lifting plate 4 is located between the conveyor belt 2 and the fixed frame 3. A cutting blade 6 is installed at the lower end of the lifting plate 4. The cutting blade 6 is connected to the lifting plate 4 by a detachable bolt. A support plate is provided on the inner side of the conveyor belt 2 below the cutting blade 6. The support plate is fixedly connected to the workbench 1.

[0020] See Figure 1 , Figure 2 , Figure 4 As shown, a telescopic cylinder 5 is provided between the upper end of the lifting plate 4 and the fixed frame 3. The telescopic cylinder 5 is a standard cylinder. The end of the cylinder piston rod is connected to the lifting plate 4 through a floating joint to compensate for installation errors and prevent the lifting plate 4 from jamming. A horizontal plate 7 is provided on one side of the fixed frame 3. Slide plates 8 are slidably installed at both ends of the horizontal plate 7. An adjustment component is provided between the slide plates 8 and the horizontal plate 7. The adjustment component includes a bidirectional threaded rod 9. The two ends of the bidirectional threaded rod 9 are rotatably installed on the horizontal plate 7. The two ends of the bidirectional threaded rod 9 are connected to the horizontal plate 7 through deep groove ball bearings.

[0021] See Figure 2 , Figure 3 As shown, the two ends of the bidirectional threaded rod 9 are respectively threaded to the corresponding slide plate 8. A drive source 18 is provided between the middle of the bidirectional threaded rod 9 and the horizontal plate 7. The drive source 18 is a servo motor. The drive source 18 is fixedly installed on the fixed frame 3. A vertical plate 10 is installed on the side of the two slide plates 8 that is far apart from each other. The lower end of the vertical plate 10 is in contact with the conveyor belt 2. A rubber pad is fixedly installed on the side of the two vertical plates 10 that is close to each other.

[0022] In this embodiment, a limiting component is installed on the side of the two sliding plates 8 that are close to each other. The limiting component includes a rotating frame 11, a roller 12 is installed at the lower end of the rotating frame 11, the roller 12 is made of polyurethane, a sliding rod 13 is rotatably installed at the upper end of the rotating frame 11, the sliding rod 13 is made of 45 steel, and a fixed cylinder 14 is slidably arranged at the upper end of the sliding rod 13. The fixed cylinder 14 is a seamless steel pipe, and the inner wall is coated with graphite grease to reduce the frictional resistance when the sliding rod 13 slides up and down. The fixed cylinder 14 is installed on the sliding plate 8.

[0023] In this embodiment, a spring 15 is provided between the slide rod 13 and the fixed cylinder 14. The spring 15 is a cylindrical helical compression spring. The spring 15 is located inside the slide rod 13. A pressure plate 16 is provided above the spring 15. An adjusting rod 17 is installed on the upper end of the pressure plate 16. The adjusting rod 17 is threadedly connected to the fixed cylinder 14. By rotating the adjusting rod 17 to change the position of the pressure plate 16, the preload of the spring 15 can be adjusted to adapt to materials of different thicknesses.

[0024] The implementation principle is as follows: The drive source 18 in the adjustment assembly is activated, causing the bidirectional threaded rod 9 to rotate around its own axis. When the bidirectional threaded rod 9 rotates, it drives two sliding plates 8 to slide synchronously in opposite directions along the length of the horizontal plate 7. The two sliding plates 8 cause the vertical plate 10 to move accordingly, ensuring that the distance between the two vertical plates 10 perfectly matches the width of the material to be cut. At this point, the drive source 18 is stopped. One end of the material to be cut is laid flat on the feed end of the conveyor belt 2. The drive motor is started, causing the drive motor's active roller to rotate. The rotation of the active roller drives the conveyor belt 2 to move at a set speed, thus smoothly conveying the material to be cut on the conveyor belt 2 towards the direction of the cutting assembly until the material to be cut is directly below the cutting blade 6. The conveyor belt 2 then pauses to ensure... Cutting position; then the telescopic cylinder 5 is activated, its piston rod extends downward, pushing the lifting plate 4 downward, and the cutting blade 6 installed at the lower end of the lifting plate 4 presses down, contacting the material surface and applying cutting force, finally completing a single material cut; during the downward pressing of the cutting blade 6, the spring 15 of the limiting component acts on the slide rod 13 through elastic force, and the slide rod 13 acts on the roller 12 through the rotating frame 11, so that the roller 12 is in close contact with the material surface; the roller 12 can directly suppress the local lifting phenomenon of the material caused by the vertical pressure of the cutting blade 6; when the cutting is completed and the telescopic cylinder 5 drives the cutting blade 6 to rise upward, the material will not move upward with the cutting blade 6 due to excessive friction with the cutting blade 6, ensuring cutting accuracy and material position stability.
