Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical cutting machines, specifically to a vertical cutting machine with quick-release blades. Background Technology
[0002] Vertical cutting machine technology is primarily used in the precision cutting of various materials. Through vertical cutting, it can quickly and efficiently divide materials, ensuring the flatness and accuracy of the cut surface. In EPE (Expanded Polyethylene) foam production, vertical cutting machines ensure dimensional consistency after cutting, meeting the needs of packaging and protective materials. Using vertical cutting machines with quick-release blades reduces downtime, improves production line continuity, lowers maintenance costs, and enhances overall production efficiency.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] Currently, the blades of common vertical cutting machines have relatively complex installation and disassembly structures. When disassembling and assembling the blades, they are usually assembled by combining multiple bolts and nuts, which makes the disassembly and assembly operations laborious and cumbersome. They also require additional tools, which reduces operating efficiency, increases operating costs, and has poor practicality. Utility Model Content
[0005] The purpose of this invention is to provide a vertical cutting machine with quick-release blades, in order to solve the problem mentioned in the background art that the disassembly and assembly operations are laborious, cumbersome, and require additional tools.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic cylinder is installed in the middle of the upper surface of the support frame, a piston rod is inserted into the inside of the hydraulic cylinder, a quick-release assembly is installed at the bottom of the piston rod, a knife holder is installed at the bottom of the quick-release assembly, and a cutter is installed at the bottom of the knife holder.
[0007] The quick-release assembly includes a sleeve mounted to the bottom of the piston rod. The bottom of the sleeve has a slot, and a connecting post is inserted into the slot. The tops of both sides of the connecting post are fitted with locking blocks.
[0008] A slider is installed in the middle of both sides of the connecting column.
[0009] The bottom ends of both sides of the connecting column are equipped with columns.
[0010] Mounting brackets are installed at the top ends of both sides of the sleeve. A sliding rod is slidably connected inside the mounting bracket, and a pressing block is installed on one side of the sliding rod.
[0011] A return spring is fitted onto the end of the slide rod near the compression block.
[0012] The top ends of both sides of the sleeve are rotatably connected to hanging rods, and the top end of the hanging rods near the sleeve is fitted with a torque spring.
[0013] The beneficial effects of this utility model are as follows: by moving one side of the hanging rod, the slot at the bottom of the hanging rod can be disengaged from the column, thereby eliminating the supporting effect on the column. Then, by simultaneously pulling the handle outward, and cooperating with the sliding rod, the pressing block can be disengaged from the through groove, thereby eliminating the obstruction of the locking block. This allows the tool holder to be gradually pulled downward, and the tool can be quickly removed. This simplifies the tool installation and disassembly structure, making tool installation and disassembly faster and more convenient, without the need for additional tools, thus improving operating efficiency, reducing operating costs, and enhancing the practicality of the equipment.
[0014] To enable the cutter to reciprocate in height along the vertical direction for cutting operations:
[0015] The cutter is further configured such that it forms a lifting structure with a hydraulic cylinder and a piston rod.
[0016] By adopting the above technical solution, the hydraulic cylinder is started by an external oil pump, which causes hydraulic oil to enter and exit the hydraulic cylinder and reciprocate to push the piston rod, thereby pushing the tool holder and the cutting blade installed inside it to perform lifting and cutting operations.
[0017] To allow the extrusion block to be pulled out from inside the through groove by the sliding rod:
[0018] The further configuration is as follows: a handle is installed on one side of the slide rod, and the extrusion block forms a pull-out structure with the slide rod through the handle. The sleeve surface has through grooves on both sides near the mounting bracket, and the internal size of the through grooves is consistent with the external size of the extrusion block.
[0019] By adopting the above technical solution, by holding the handle and pulling it outward, the slide bar and the extrusion block are moved horizontally, thereby causing the extrusion block to disengage from the through groove and eliminating the obstruction to the jamming block inside the sleeve.
[0020] To ensure the card block can be pressed into the slotted inner cavity by the extrusion block:
[0021] The configuration is further defined as follows: both the pressing block and the card block have one inclined surface.
[0022] By adopting the above technical solution, the connecting post is aligned with the slot opened at the bottom of the sleeve and slid in. As it moves, the locking block is squeezed into the inner cavity of the slot through the inclined surface of one side of the squeezing block.
[0023] To ensure the locking block is continuously subjected to the elastic thrust of the return spring and remains embedded inside the slot:
[0024] The compression block is further configured such that it forms a buffer structure with the mounting frame via a reset spring.
[0025] By adopting the above technical solution, the reset sleeve is attached to one end of the slide bar that extends into the mounting bracket, so that one side of it is in contact with the inner wall of the mounting bracket and the other side is in contact with the extrusion block. The reset spring is compressed and its elastic force is used to continuously push the extrusion block into the through groove, thereby blocking the internal locking block.
[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0033] Please see Figures 1 to 4 A vertical cutting machine with quick-release blades includes a worktable 1, a support frame 2 installed in the middle of the upper surface of the worktable 1, a hydraulic cylinder 3 installed in the middle of the upper surface of the support frame 2, a piston rod 4 inserted inside the hydraulic cylinder 3, a quick-release assembly 5 installed at the bottom of the piston rod 4, a blade holder 6 installed at the bottom of the quick-release assembly 5, and a cutting blade 7 installed at the bottom of the blade holder 6.
[0034] The quick-release assembly 5 includes a sleeve 501 installed at the bottom of the piston rod 4. The bottom of the sleeve 501 has a slot 502, and a connecting post 503 is inserted into the slot 502. The top of both sides of the connecting post 503 is fitted with a locking block 504.
[0035] Slider 505 is installed in the middle of both sides of the connecting column 503.
[0036] Uprights 506 are installed at the bottom of both sides of the connecting column 503.
[0037] Mounting brackets 507 are installed at the top of both sides of the sleeve 501. A sliding rod 508 is slidably connected inside the mounting bracket 507. An extrusion block 509 is installed on one side of the sliding rod 508.
[0038] A return spring 510 is sleeved on one end of the slide bar 508 near the pressing block 509.
[0039] The top ends of both sides of the sleeve 501 are rotatably connected to the hanging rods 511, and the top end of the hanging rods 511 near the sleeve 501 is fitted with a torque spring 512.
[0040] In this embodiment, as Figure 2 As shown, the cutter 7 forms a lifting structure with the piston rod 4 via the hydraulic cylinder 3.
[0041] In this embodiment, as Figure 3 As shown, a handle is installed on one side of the slide bar 508, and the extrusion block 509 forms a pull-out structure with the slide bar 508 through the handle. The sleeve 501 has through slots on both sides near the mounting bracket 507, and the internal size of the through slots is consistent with the external size of the extrusion block 509.
[0042] In this embodiment, as Figure 4 As shown, both the pressing block 509 and the clamping block 504 have inclined surfaces on one side.
[0043] In this embodiment, as Figure 3 As shown, the compression block 509 forms a buffer structure with the mounting bracket 507 via the return spring 510.
[0044] The working process of this vertical cutting machine with quick-release blades is as follows:
[0045] First, when it is necessary to disassemble and replace the cutter 7 built into the vertical cutter, by moving one side of the hanging rod 511, the slot at the bottom of the hanging rod 511 is driven to disengage from the column 506. Then, the handles at both ends of the sleeve 501 are held and pulled outward, thereby using the slide rod 508 to drive the extrusion block 509 out of the through groove. This removes the obstruction of the internal locking block 504. At this point, slowly drag the tool holder 6 downwards to disengage the connecting post 503 from the slot 502, allowing the cutter 7 to be removed for easy maintenance and replacement. Once the cutter 7 is maintained or replaced, align the connecting post 503 with the slot 502 at the bottom of the sleeve 501 and lift the tool holder 6 upwards. The connecting post 503 will then slide into the slot 502. At this time, the inclined surface of the locking block 504 will be compressed by the pressing block 509, causing the pressing block 509 to move outwards. Simultaneously, the return spring 510 retracts. Once the locking block 504 is fully embedded in the inner cavity of the slot 502, it will no longer be subjected to pressure. When the extrusion block 509 is pressed, the elastic force of the return spring 510 pushes the extrusion block 509 back into the through groove, blocking the locking block 504. Finally, by moving the hanging rod 511 again, the slot at the bottom of the hanging rod 511 is locked onto the surface of the column 506. At the same time, the elastic force of the torque spring 512 ensures the supporting effect of the hanging rod 511 on the column 506. This completes the quick-release replacement of the cutter 7. After completion, the hydraulic cylinder 3 can be started by the external oil pump, which causes the hydraulic oil to enter the hydraulic cylinder 3 and push the piston rod 4 to work, thereby pushing the cutter holder 6 and the cutter 7 installed inside it to perform the cutting operation.
