[0001] This application relates to the field of cutting tool technology, and in particular to a quick-release cutting tool. Background Technology

[0002] Cutting tools are key tools in mechanical manufacturing. Their performance directly affects processing efficiency, precision, and surface quality. Cutting knives are specialized tools used to cut, trim, or slit materials and are widely used in food processing, wood processing, and many other fields.

[0003] After a period of operation, the cutting edge of a cutting tool will wear down, so it needs to be replaced regularly to ensure milling performance. In related technologies, the cutting tool is installed by fixing the cutter head to the drive end of the processing equipment with mounting bolts.

[0004] The aforementioned cutting blades require operators to use tools during disassembly, making it difficult to quickly replace worn cutting blades, resulting in low disassembly and assembly efficiency and affecting the production efficiency of processing equipment. Summary of the Invention

[0005] To address the problem in related technologies where disassembly of cutting blades requires manual tools, hindering rapid replacement of worn blades and resulting in low disassembly efficiency, this application provides a quick-release cutting blade with the following technical solution: It includes a mounting frame and a cutting unit. The mounting frame has a fixed base with a sliding hole. A mounting sleeve is slidably connected within the sliding hole. A connector is slidably connected to the inner edge of the mounting sleeve. The cutting unit is mounted on the connector. A quick-release groove is formed on the wall of the sliding hole, and a placement groove is formed on the mounting sleeve. A ball bearing is placed in the placement groove. When the mounting sleeve slides along the sliding hole, the ball bearing moves between the quick-release groove and the sliding hole.

[0006] In one specific implementation, the connector is a CNC rivet, which includes a connecting block connected to the cutting unit. The connecting block is provided with a locking block, and the outer edge of the locking block is provided with a locking groove. When the ball is pressed against the sliding hole and the locking groove, the cutting unit is in a locked state. When the ball is pressed against the quick-release groove and the placement groove, the cutting unit is in a disassembled state.

[0007] In one specific implementation, the mounting bracket is provided with a drive unit for driving the mounting sleeve to slide along the sliding hole. The drive unit includes a drive cylinder disposed on the mounting bracket, and the output end of the drive cylinder is provided with a drive plate. The mounting sleeve is disposed on the drive plate.

[0008] In one specific implementation, the drive cylinder is positioned on one side of the fixed base.

[0009] In one specific implementation, a compression spring is fitted around the outer edge of the fixed base, and the compression spring abuts against the drive plate and the fixed base.

[0010] In one specific implementation, the cutting unit includes a blade holder disposed on a connector, the blade holder having a cutting blade.

[0011] In one specific implementation, the mounting bracket has a trapezoidal groove that matches the tool holder, and the tool holder is partially inserted into the inner edge of the trapezoidal groove.

[0012] In one specific implementation, the mounting frame has two mounting holes, and pressure rods are slidably connected in the two mounting holes. Pressure blocks are provided at the ends of the two pressure rods away from the mounting frame. The two pressure blocks are connected by a connecting plate, and a guide groove is provided between the two pressure blocks. The cutting blade is located between the guide grooves. An elastic element is provided between the pressure block and the mounting frame. A limiting component for controlling the movement direction of the pressure block is provided on the blade holder.

[0014] In one specific implementation, a bushing is provided between the pressure rod and the mounting hole.

[0015] In summary, this application has the following beneficial technical effects: when the cutting unit needs to be disassembled, the mounting sleeve moves down along the sliding hole, driving the ball located at the sliding hole to move to the quick-release groove. The ball releases its limit on the connector, allowing the connector to be smoothly pulled out from the inner edge of the mounting sleeve, realizing the quick disassembly and replacement of the cutting unit. Operators do not need to use external tools for disassembly and assembly, making it easy and convenient, improving the efficiency of tool replacement, and thus improving the production efficiency of the processing equipment.

[0020] The present application will be further described in detail below with reference to Figures 1-3.

[0021] This application discloses a quick-release cutting knife.

[0022] Referring to Figures 1 and 2, the quick-release cutting blade 14 includes a mounting frame 1 and a cutting unit. A fixing seat 2 is bolted to the mounting frame 1. A sliding hole 3 is provided on the fixing seat 2. A mounting sleeve 4 matching the size of the sliding hole 3 is slidably connected in the sliding hole 3. A connector is slidably connected to the inner edge of the mounting sleeve 4. The cutting unit is set on the connector. In this embodiment, the connector is a CNC rivet. The CNC rivet includes a connecting block 7 connected to the cutting unit. A locking block 8 is fixedly connected to the top of the connecting block 7. A locking groove 9 is provided on the outer edge of the locking block 8. The locking block 8 passes through the mounting frame 1 and is located on the inner edge of the mounting sleeve 4.

[0023] Referring to Figures 1 and 2, a quick-release groove 5 is provided on the wall of the sliding hole 3. In this embodiment, a transition groove is provided between the quick-release groove 5 and the sliding hole 3, and the diameter of the quick-release groove 5 is larger than the diameter of the sliding hole 3. A placement groove is provided on the mounting sleeve 4, and a ball bearing 6 is placed in the placement groove. In this embodiment, the number of balls bearing 6 can be set to several according to the actual situation, and the several balls bearing 6 are evenly distributed along the outer edge of the mounting sleeve 4. When the mounting sleeve 4 slides along the sliding hole 3, the balls bearing 6 move between the quick-release groove 5 and the sliding hole 3. When the ball bearing 6 is pressed between the sliding hole 3 and the locking groove 9, the ball bearing 6 is located in the small-diameter sliding hole 3. The ball bearing 6 presses against the locking block 8 at the locking groove 9 to limit the position of the connector, thereby gripping the connector and the cutting unit is in a locked state. When the ball bearing 6 is pressed between the quick release groove 5 and the placement groove, the ball bearing 6 is located in the large-diameter quick release groove 5. The ball bearing 6 releases the limit on the connector, allowing the connector to be smoothly pulled out from the inner edge of the mounting sleeve 4, and the cutting unit is in a detachable state.

[0024] Referring to Figures 1 and 2, the cutting unit includes a blade holder 13 mounted on the connecting block 7, and a cutting blade 14 is mounted on the blade holder 13. The mounting frame 1 has a trapezoidal groove 15 that matches the size of the blade holder 13. The blade holder 13 is partially inserted into the inner edge of the trapezoidal groove 15. The trapezoidal groove 15 limits the position of the mounting frame 1, reduces the possibility of positional deviation of the mounting frame 1, and improves the stability of the mounting frame 1.

[0025] Therefore, when the tool holder 13 needs to be disassembled, the mounting sleeve 4 moves downward along the sliding hole 3, causing the ball bearing 6 located at the sliding hole 3 to move to the quick-release groove 5. The ball bearing 6 releases its restraint on the connector, allowing the connector to be smoothly pulled out from the inner edge of the mounting sleeve 4, realizing the quick disassembly and replacement of the cutting unit. Operators do not need to use external tools for disassembly and assembly, making it easy and convenient, improving tool replacement efficiency, and thus improving the production efficiency of the processing equipment. When the tool holder 13 needs to be installed, the mounting sleeve 4 is moved upward along the sliding hole 3, and the ball bearing 6 enters the small-diameter sliding hole 3. The ball bearing 6 presses against the locking block 8 at the locking groove 9 to restrain the position of the connector, thereby gripping the connector and realizing the installation of the tool holder 13.

[0026] Referring to Figures 1 and 2, the mounting frame 1 is equipped with a drive unit for driving the mounting sleeve 4 to slide along the sliding hole 3. The drive unit includes a drive cylinder 10 vertically mounted on the mounting frame 1, and a drive plate 11 is mounted on the output end of the drive cylinder 10. The mounting sleeve 4 is mounted on the drive plate 11. Therefore, when the drive cylinder 10 is activated, the drive plate 11 at the output end of the drive cylinder 10 is raised and lowered. During the raising and lowering of the drive plate 11, the mounting sleeve 4 is raised and lowered along the sliding hole 3. The drive cylinder 10 is located on one side of the fixed base 2, which saves space in the mounting frame 1 while driving the drive plate 11. A compression spring 12 is sleeved on the outer edge of the fixed base 2. The compression spring 12 is pressed between the drive plate 11 and the fixed base 2. Through the elastic compression of the compression spring 12, the compression spring 12 absorbs the impact energy generated during movement through elastic deformation and converts it into elastic potential energy for slow release. This can effectively reduce the vibration amplitude during operation and improve the stability of the drive plate 11 during the raising and lowering process.

[0027] Referring to Figures 1 and 2, the mounting bracket 1 has two mounting holes, and pressure rods 16 are slidably connected in the two mounting holes respectively. A bushing 22 is provided between the pressure rod 16 and the mounting hole. The bushing 22 can reduce the direct contact between the pressure rod 16 and the mounting hole, reduce the coefficient of friction between the two, thereby reducing wear caused by friction and extending the service life of the pressure rod 16 and the mounting bracket 1.

[0028] Referring to Figures 1 and 2, two pressure rods 16 are bolted to pressure blocks 17 at their ends away from the mounting frame 1. The two pressure blocks 17 are connected by a connecting plate 23, and a guide groove 18 is provided between the two pressure blocks 17. The cutting blade 14 is located between the guide grooves 18. The guide grooves 18 limit the lifting and lowering of the cutting blade 14, improving the accuracy of the cutting blade 14 during the cutting process. An elastic element 19 is provided between the pressure block 17 and the mounting frame 1. In this embodiment, the elastic element 19 is a return spring. A limiting component for controlling the movement direction of the pressure block 17 is provided on the blade holder 13. The limiting component includes a guide rail 20 vertically arranged on the blade holder 13. A slider 21 matching the size of the guide rail 20 is slidably connected on the guide rail 20. The pressure block 17 is placed on the slider 21. The guide rail 20 limits the movement direction of the slider 21, thereby further improving the stability of the pressure block 17 during the lifting and lowering process.

[0029] Therefore, when material needs to be cut, the mounting frame 1 is pressed down by an external drive component, which in this embodiment can be a cylinder. The pressing down of the mounting frame 1 causes the pressure block 17 to first press against the material, reducing the possibility of positional displacement during material slicing. The material provides a reaction force to the pressure block 17, compressing the elastic element 19. The cutting blade rises and falls to achieve cutting. After the material is sliced, the external drive component causes the mounting frame 1 to rise, and the elastic element 19 loses the force of the material and resets, resetting the cutting blade 14 back into the guide groove 18, reducing the possibility of the cutting blade 14 being exposed.

[0030] The implementation principle of this application embodiment is as follows: When the tool holder 13 needs to be disassembled, the drive cylinder 10 is activated, which drives the drive plate 11 at the output end of the drive cylinder 10 to descend. During the descent of the drive plate 11, the mounting sleeve 4 moves down along the sliding hole 3, which moves the ball bearing 6 located at the sliding hole 3 to the quick-release groove 5. The ball bearing 6 releases its limit on the connecting part, allowing the connecting part to be smoothly pulled out from the inner edge of the mounting sleeve 4, realizing the quick disassembly and replacement of the cutting unit. The operator does not need to use external tools for disassembly and assembly, which is easy and convenient, improving the efficiency of tool replacement and thus improving the production efficiency of the processing equipment. When the tool holder 13 needs to be installed, the drive cylinder 10 is activated, which drives the drive plate 11 at the output end of the drive cylinder 10 to rise, which drives the mounting sleeve 4 to move up along the sliding hole 3. The ball bearing 6 enters the small-diameter sliding hole 3. The ball bearing 6 presses the locking block 8 at the locking groove 9 to limit the position of the connecting part, thereby gripping the connecting part and realizing the installation of the tool holder 13.
