[0027] The present utility model provides a drainage board cutting device 100.

[0028] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the drainage board cutting device 100 includes: a base 1; a first connecting seat 2, the first connecting seat 2 is connected to the base 1, and the first connecting seat 2 and the base 1 enclose a cutting channel 2a; and a cutting part 3, the cutting part 3 is located in the cutting channel 2a, the cutting part 3 is slidably connected to the first connecting seat 2, and the cutting part 3 includes a positioning seat 31, a slider 32 and a cutter 33; the positioning seat 31 has a mounting groove 31a with the notch facing downwards, the slider 32 is slidably arranged in the mounting groove 31a and can be fixed at any position when sliding up and down relative to the positioning seat 31.

[0029] In this embodiment, the base 1 is the basic support of the cutting device. The base 1 has a cutting plane and four legs. The cutting plane of the base 1 is relatively horizontal, and the operator can easily place and cut the drainage board; the base 1 is generally made of steel or high-strength alloy materials. Since the base 1 needs to bear the weight of the entire cutting device and the drainage board raw material, the material for making the base 1 needs to have good stability and durability to ensure that the base 1 does not vibrate or deform during the normal cutting process of the drainage board cutting device 100.

[0030] A cutting channel 2a is formed by enclosing between the first connecting seat 2 and the base 1. One end of the first connecting seat 2 is connected to the base 1 by means of bolt connection or snap connection, etc., or both ends of the first connecting seat 2 are respectively connected to the base 1 by means of bolt connection or snap connection, etc.; The first connecting seat 2 is generally made of steel or aluminum alloy material. Steel is a widely used metal material, known for its excellent mechanical properties and workability. It has a high tensile strength and good toughness, can withstand heavy loads and impacts, and is easy to process by methods such as forging, rolling and welding. In addition, the durability of steel enables it to resist various environmental factors, and due to its recyclability, steel is also an environmentally friendly material. The aluminum alloy material is lighter in weight and has a high thermal conductivity. Especially in applications where weight reduction and energy efficiency improvement are required, the corrosion resistance of the aluminum alloy benefits from the natural oxide film formed on its surface, which gives it a long service life in outdoor applications. Its high thermal conductivity can also be used for the heat dissipation of the cutting part 3. The aluminum alloy is also very easy to process and can be made into various shapes by methods such as casting and extrusion. The first connecting seat 2 has high stability and wear resistance, and is mainly used to carry the operation of the cutting part 3 on the base 1.

[0031] In one embodiment, the cutting part 3 is located in the cutting channel 2a. The cutting part 3 is slidably arranged on the first connecting seat 2. The cutting part 3 includes a positioning seat 31, a slider 32 and a cutting tool 33; The slider 32 is slidably arranged in the installation groove 31a and can be fixed at any position when sliding up and down relative to the positioning seat 31. The height of the slider 32 can be accurately positioned by bolts in cooperation with thread locking, or the positioning of the slider 32 and the adjustment of the height of the cutting tool 33 can be achieved by setting pin holes on the slider 32 and using a pin shaft to cooperate with the pin holes. The cutting part 3 drives the cutting tool 33 to cut the drainage board material by sliding on the first connecting seat 2; The cutting tool 33 is detachably connected to the slider 32 by means of bolts or pins, etc. The slider 32 is slidably arranged in the installation groove 31a of the positioning seat 31, and the height adjustment of the cutting tool 33 is realized by the up and down sliding of the slider 32 in the installation groove 31a.

[0032] The technical solution of the present utility model adopts a split design of the cutting knife 33 and the mounting seat. The cutting knife 33 is detachably connected to the slider 32 by means of bolt connection or pin connection. The height of the cutting knife 33 is adjusted by the up and down sliding of the slider 32 in the mounting groove 31a of the mounting seat, and the position of the slider 32 is fixed by means of bolt connection or pin connection. The height of the cutting knife 33 can be adjusted according to the thickness of the cutting material. The cutting knife 33 makes a reciprocating motion on the first connecting seat 2 through the mounting seat to cut the drainage board. After use, the cutting knife 33 is adjusted upward to separate the cutting knife 33 from the drainage board, so as to solve the problem that when the existing cutting device for drainage board production is in use, the height of the cutting knife 33 is not easy to adjust, which results in easy dulling of the contact between the cutting edge of the cutting knife 33 and the drainage board, affecting the service life of the cutting knife 33 and thus affecting the cutting quality.

[0033] In an embodiment of the present utility model, please refer to Figure 3 , the cutting part 3 includes a positioning knob 34. A locking hole 311 communicating with the mounting groove 31a is provided on the side wall of the positioning seat 31. The outer wall of the positioning knob 34 is in threaded cooperation with the inner wall of the locking hole 311, and the positioning knob 34 abuts against the slider 32.

[0034] In this embodiment, the positioning seat 31 has four side walls. A locking hole 311 communicating with the mounting groove 31a is provided on one of the side walls. The outer wall of the positioning knob 34 is in threaded cooperation with the inner wall of the locking hole 311. The positioning knob 34 abuts against the slider 32 through the locking hole 311, so as to precisely control the position of the slider 32. This design enables the operator to lock or release the slider 32 by rotating the positioning knob 34, realizing the rapid adjustment of the height of the cutting knife 33. We not only improve the positioning accuracy of the height of the cutting knife 33, but also enhance the operation convenience and flexibility of the entire cutting device.

Specifically, a cutting groove 12 is provided directly below the guide rod 21. When the operator needs to perform a cutting operation, the cutting edge of the cutting knife 33 needs to be adjusted to be lower than the cutting groove 12 on the base 1. When the guide rod 21 drives the slider 32 and the cutting knife 33 to move along the direction of the guide rod 21, the cutting edge of the cutting knife 33 can cut the material along the cutting groove 12. The width of the cutting groove 12 matches the shape and size of the cutting knife 33, ensuring the stability and safety of the cutting knife 33 during the cutting process and increasing the cutting force of the cutting knife 33.

The guiding rods 21 are generally made of alloy steel or stainless steel, and such materials have good corrosion resistance and wear resistance, and can be rotatably matched with the cutting part 3 for a long time to realize the reciprocating movement of the cutting part 3. The internal threads on the inner wall of the guiding hole 312 are matched with the external threads on the outer periphery of the guiding rod 21. When the guiding rod 21 rotates, the positioning seat 31 slides along the axial direction of the guiding rod 21 and realizes precise positioning. Through the meshing of such threads, the guiding rod 21 can stably rotate in the guiding hole 312 to ensure that the slider 32 and the cutter 33 assembly perform accurate cutting along a predetermined direction. This design not only provides a stable guiding function, but also can adjust the cutting position by screwing in and out the threads, so as to adapt to different cutting requirements.

[0039] In an embodiment of the present utility model, please refer to Figure 2 , the first connecting seat 2 is provided with a servo motor 22, the servo motor 22 is detachably connected to the first connecting seat 2, and the guiding rod 21 is detachably connected to the output end of the servo motor 22.
