Description

Technical Field

[0001] This utility model relates to the field of woodworking equipment, and in particular to an edge banding strip cutting device for edge banding machines. Background Technology

[0002] In industries such as furniture manufacturing and board processing, edge banding machines are the core equipment for edge banding of boards. By wrapping the edges of the boards with edge banding strips, they can effectively improve the aesthetics, moisture resistance and structural stability of the boards. As a key supporting component of the edge banding machine, the edge banding strip cutting device directly determines the dimensional accuracy and cut flatness of the edge banding strip after cutting, which has an important impact on the final product quality.

[0003] The cutting mechanism has a fixed height and cannot be flexibly adjusted according to the thickness range of the edge banding. When dealing with thicker edge banding, the blade cannot fully contact the cutting surface, which can easily lead to problems such as incomplete cutting and rough edges. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an edge banding strip cutting device for edge banding machines, which aims to improve the problem that existing cutting devices cannot adaptively adjust according to the thickness of the edge banding strip and have low cutting accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an edge banding strip cutting device for an edge banding machine, comprising a mounting base, a worm gear rotatably connected to the inner wall of the mounting base, a lifting rod threadedly connected to the inner wall of the worm gear, a knife holder slidably connected to the outer wall of the lifting rod, a first spring slidably connected to the outer wall of the lifting rod, a first guide rod fixedly connected to the inner wall of the mounting base, a motor mounted on the inner wall of the knife holder, a knife fixedly connected to the output end of the motor, an adapter block fixedly connected to the outer wall of the knife holder, a worm gear rotatably connected to the inner wall of the mounting base, and a collecting assembly provided at the bottom end of the mounting base.

[0006] According to the above technical solution, the worm gear is rotated to drive the worm wheel to rotate, which in turn causes the lifting rod to rotate, thereby realizing the up and down movement of the lifting rod. Under the action of the frustum on the surface of the lifting rod, the tool holder rises with the lifting rod, and under the action of its own weight, it falls with the lifting rod. The first guide rod is used to guide the movement path of the tool holder and prevent deviation. The above components can realize the height adjustment of the tool to adapt to the cutting of edge banding strips of different widths. The adapter block and the first spring work together to compensate for the slight fluctuations in the thickness of the edge banding strip during the cutting process, ensuring that the tool and the cutting surface are in close contact.

[0007] Preferably, the collecting component includes a collecting port, the upper surface of which is mounted on the bottom end of the mounting base, a bolt threaded to the inner wall of the collecting port, a hose fixedly connected to the bottom end of the collecting port, a collecting chamber fixedly connected to the other end of the hose, and a drawer slidably connected to the inner wall of the collecting chamber.

[0008] Preferably, a second guide rod is fixedly connected to the inner wall of the mounting base, a slider is slidably connected to the outer wall of the second guide rod, a rubber roller is fixedly connected to the outer wall of the slider, and a second spring is slidably connected to the outer wall of the second guide rod.

[0009] Preferably, the upper surface of the mounting base is provided with a limiting plate, and the surface of the mounting base is provided with multiple mounting holes.

[0010] Preferably, a rocker arm is provided at one end of the worm gear.

[0011] Preferably, the surface of the lifting rod is provided with a frustum, the lower surface of the tool holder is slidably connected to the upper surface of the frustum, and the surface of the lifting rod is rotatably connected to the inner wall of the tool holder.

[0012] Preferably, the upper surface of the collection chamber is provided with a connecting threaded hole.

[0013] Preferably, the lower surface of the mounting base has a threaded hole, and the surface thread of the bolt is connected to the threaded hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the worm gear drives the worm wheel to rotate the lifting rod, thereby moving the lifting rod up and down, which in turn moves the knife holder. The first guide rod ensures that the knife holder does not deviate during movement, thus accurately adjusting the knife height to adapt to cutting edge banding strips of different widths. The adapter block and the first spring work together to compensate for slight fluctuations in the thickness of the edge banding strip, ensuring that the knife and the cutting surface are always in close contact, resulting in more stable cutting.

[0016] 2. In this utility model, a negative pressure system is connected to the collection chamber to create a negative pressure space inside the collection chamber. Suction is generated from the collection port to suck in the corners generated during the cutting process. The corners are then drawn into the collection chamber through a hose to complete the collection. The waste can then be quickly cleaned through a drawer, achieving simultaneous collection and rapid cleaning of waste materials and improving work efficiency. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of an edge banding machine edge banding strip cutting device, including a mounting base 1, a worm gear 17 rotatably connected to the inner wall of the mounting base 1, a lifting rod 3 threadedly connected to the inner wall of the worm gear 17, a knife holder 2 slidably connected to the outer wall of the lifting rod 3, a first spring 4 slidably connected to the outer wall of the lifting rod 3, a first guide rod 5 fixedly connected to the inner wall of the mounting base 1, a motor 6 mounted on the inner wall of the knife holder 2, a knife 7 fixedly connected to the output end of the motor 6, an adapter block 8 fixedly connected to the outer wall of the knife holder 2, a worm gear 18 rotatably connected to the inner wall of the mounting base 1, and a collecting assembly provided at the bottom end of the mounting base 1.

[0025] Specifically, the worm gear 18 drives the worm wheel 17 to rotate, which in turn drives the lifting rod 3 to rotate and move up and down. When rising, the frustum on the surface of the lifting rod 3 actively pushes the tool holder 2. When falling, the tool holder 2 falls due to its own weight. With the first guide rod 5 constraining the movement path, this component can quickly and accurately complete the height adjustment of the tool 7, easily adapting to the cutting needs of edge banding strips of different widths, greatly improving the versatility of the equipment. At the same time, the adapter block 8 and the first spring 4 form a flexible compensation mechanism. When the edge banding strip is too thick, the adapter block 8 is lifted up, and the tool holder 2 also moves upward. Under the action of the first spring 4, the tool 7 is made to fit tightly with the cutting surface. The adapter block 8 has an arc design, which makes it easier for the board to pass through, effectively ensuring the stability of cutting accuracy and cut quality.

[0026] Reference Figure 4 The collection component includes a collection port 13, the upper surface of which is mounted on the bottom of the mounting base 1. A bolt 19 is threadedly connected to the inner wall of the collection port 13. A hose 15 is fixedly connected to the bottom of the collection port 13. A collection chamber 14 is fixedly connected to the other end of the hose 15. A drawer 16 is slidably connected to the inner wall of the collection chamber 14.

[0027] Specifically, the scraps generated during the cutting process can be sucked up immediately and quickly transported to the collection bin 14 through the hose 15, achieving simultaneous collection of waste materials and the cutting process, thus preventing waste accumulation at the source. After collection, the bin can be quickly cleaned by simply pulling out the drawer 16. The entire process is convenient, maintaining a clean working environment, significantly reducing manual cleaning time, and greatly improving overall work efficiency.

[0028] Reference Figure 1 The inner wall of the mounting base 1 is fixedly connected to a second guide rod 11, the outer wall of the second guide rod 11 is slidably connected to a slider 10, the outer wall of the slider 10 is fixedly connected to a rubber roller 9, and the outer wall of the second guide rod 11 is slidably connected to a second spring 12.

[0029] Specifically, this prevents the board from shifting under stress during the cutting process, which could affect the cutting results.

[0030] Reference Figure 1 A limit plate is provided on the upper surface of the mounting base 1, and multiple mounting holes are provided on the surface of the mounting base 1.

[0031] Specifically, the limiting plate ensures the stability of the material's movement trajectory, allows the cutter 7 to fit tightly against the cutting surface, and the mounting hole allows the entire device to be fixed on the outside of the edge banding machine.

[0032] Reference Figure 2 A rocker arm is provided at one end of the worm gear 18.

[0033] Specifically, the increased torque of the rocker arm allows the user to rotate the worm gear 18 with less force, reducing the force required for manual operation and balancing ease of operation with labor-saving features.

[0034] Reference Figure 2 The surface of the lifting rod 3 is provided with a frustum, the lower surface of the tool holder 2 is slidably connected to the upper surface of the frustum, and the surface of the lifting rod 3 is rotatably connected to the inner wall of the tool holder 2.

[0035] Specifically, the truncated cone provides stable upper surface support for the tool holder 2, effectively limiting the downward travel of the tool holder 2 along the lifting rod 3, and also ensuring the stability of the tool holder 2 during sliding, avoiding deviation and swaying.

[0036] Reference Figure 4The upper surface of the collection chamber 14 is provided with a connecting threaded hole.

[0037] Specifically, the threaded hole is used to connect to a negative pressure system.

[0038] Reference Figure 4 The lower surface of the mounting base 1 has a threaded hole, and the surface of the bolt 19 is threaded into the threaded hole.

[0039] Specifically, the collection port 13 can be fixed to the lower surface of the mounting base 1.

[0040] Working principle: When using this device, first fix the device to the outside of the edge banding machine through the mounting holes of the mounting base 1. Rotate the rocker arm at one end of the worm gear 18 to drive the worm gear 18 to mesh with the worm wheel 17 and rotate, so that the lifting rod 3, which is threaded to the worm wheel 17, moves up and down. The truncated cone on the surface of the lifting rod 3 pushes the knife holder 2 along the first guide rod 5, thereby adjusting the height of the knife 7 to adapt to edge banding strips of different widths. When the board enters along the limiting plate, it pushes the rubber roller 9 to compress the second spring 12. The elasticity of the second spring 12 makes the rubber roller 9 press the board tightly to prevent displacement. Start the motor 6 to drive the knife 7 to cut. If the edge banding strip is too thick, the arc-shaped adapter block 8 is lifted, which drives the knife holder 2 to move up and compress the first spring 4. The restoring force of the first spring 4 ensures that the knife 7 is in close contact with the cutting surface to stabilize the cutting accuracy. The waste generated by cutting enters the collection chamber 14 through the collection port 13 and the hose 15 under the action of the negative pressure system. Finally, the drawer 16 can be pulled out to complete the cleaning, realizing the precision, stability and efficiency of the entire cutting process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
