Description

Technical Field

[0001] This utility model relates to the field of slitting device technology, specifically a slitting device with a guiding mechanism. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes and single-layer cardboard boxes. Common cardboard boxes have three or five layers, with each layer consisting of linerboard, corrugated paper, core paper, and facing paper. In cardboard box production, the cardboard needs to be cut, thus requiring a cutting device. A Chinese utility model patent (publication number: CN221517957U) discloses a cutting device that uses a fixed plate within the cutting mechanism. This fixed plate exerts external pressure on the cardboard to be cut, solving the problem of cardboard shifting during cutting due to the lack of external pressure. Furthermore, the cutter is a single blade, eliminating the problem of a rough cut surface.

[0003] However, the above-mentioned device still has some shortcomings in use: since the cutter is mounted on the support frame and there are fixed plates and support rods on both sides of the cutter, when the cutter is worn out after long-term use and needs to be replaced, the disassembly process is inconvenient and time-consuming due to the limitations of the above-mentioned structure, which reduces work efficiency. Therefore, in view of the above situation, a slitting device with a guiding mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device with a guiding mechanism. Through the design of structures such as Z-shaped rods, mounting plates, cross grooves and positioning blocks, the disassembly and replacement process is simplified, thereby significantly improving the convenience of disassembly and replacement and solving the problems of inconvenience and time-consuming disassembly process, which reduces work efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a cutting device with a guiding mechanism, including a worktable and a positioning block. Two Z-shaped rods are provided on each side of the top of the worktable, with a gap between the two Z-shaped rods on the same side. A top plate is provided on the top of the four Z-shaped rods, and a guide rod is provided at the bottom of the top plate. The bottom of the guide rod is fixedly connected to the worktable. A mounting plate is mounted on the top plate in a height-adjustable manner. The mounting plate has a cross groove and two notches, both of which communicate with the cross groove. Screw holes are provided on both notches. A round hole is provided on the mounting plate, which fits with the guide rod with a clearance fit. The positioning block is convex and has two perforated plates. When a tool is slidably fitted in the cross groove, the positioning block is inserted into the cross groove and abuts against the end of the tool. The perforated plates fit with the notches, and bolts are inserted into the holes of the perforated plates, with the protruding ends of the bolts threaded into the screw holes.

[0007] Furthermore, a through hole is provided at the top of the top plate, and a first cylinder is provided at the top of the top plate. The moving end of the first cylinder passes through the through hole and is fixedly connected to a connecting block. A mounting plate is fixedly connected to the bottom of the connecting block.

[0008] Furthermore, the connecting block is shaped like an inverted "U".

[0009] Furthermore, a slot is provided on the top of the worktable, located directly below the cutting tool.

[0010] Furthermore, the cutting tool includes a convex seat that slides in conjunction with a cross groove. A cutting blade body is provided at the bottom of the convex seat and extends downward through the cross groove.

[0011] Furthermore, a guide assembly is provided on the top of the workbench. The guide assembly includes a second cylinder, which is fixed on the workbench. A guide plate is fixedly connected to the moving end of the second cylinder.

[0012] Furthermore, there are two fixing components at the bottom of the mounting plate.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, through the design of structures such as Z-shaped rods, mounting plates, cross grooves, and positioning blocks, allows workers to easily disassemble and replace tools through the gap between the two Z-shaped rods when it is necessary to change them. The disassembly process is not interfered with by other structures, simplifying the disassembly and replacement process and thus significantly improving the convenience of disassembly and replacement.

[0015] This utility model, through its structural design of notches, screw holes, hole plates, and bolts, allows workers to unscrew the bolts and remove the positioning block, enabling the tool to slide out of the cross groove for disassembly and replacement, making the operation convenient.

[0016] This invention, through the structural design of a circular hole and a guide rod, can guide the top plate when it descends to allow the cutter to perform the cutting operation. This can effectively reduce the shaking and tilting of the top plate during the descent process and improve the quality of the cutting operation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a slitting device with a guiding mechanism, including a worktable 1 and a positioning block 8. Z-shaped rods 2 are provided on both sides of the top of the worktable 1, with two Z-shaped rods 2 on each side. There is a gap between the two Z-shaped rods 2 on the same side. A top plate 3 is provided on the top of the four Z-shaped rods 2, and a guide rod 9 is provided at the bottom of the top plate 3. The bottom of the guide rod 9 is fixedly connected to the worktable 1.

[0025] There are four guide rods 9, arranged in a rectangular pattern.

[0026] A mounting plate 6 is mounted on the top plate 3 in a height-adjustable manner. The mounting plate 6 has a cross groove 601 and a notch 602. There are two notches 602, and both notches 602 are connected to the cross groove 601. Each notch 602 has a screw hole 6020. There are four round holes 603 on the mounting plate 6, which are arranged in a rectangular shape. The round holes 603 are clearance-fitted with the guide rod 9.

[0027] The top plate 3 has a through hole at its top, and a first cylinder 4 is installed at the top of the top plate 3. The moving end of the first cylinder 4 passes through the through hole and is fixedly connected to a connecting block 5. The bottom of the connecting block 5 is fixedly connected to an mounting plate 6.

[0028] The connecting block 5 is in the shape of an inverted "U". The inverted "U" shaped connecting block 5 is connected to the mounting plate 6, which will not interfere with the subsequent installation and removal of the tool 7.

[0029] The positioning block 8 is convex and has a hole plate 801. There are two hole plates 801. When the cutting tool 7 is slidably fitted in the cross groove 601, the positioning block 8 is inserted into the cross groove 601 and abuts against the end of the cutting tool 7. The hole plate 801 fits with the notch 602. The bolt 802 is inserted into the hole of the hole plate 801 and the protruding end of the bolt 802 is threaded into the screw hole 6020.

[0030] In this embodiment, when it is necessary to replace the fixing component 10, first unscrew the bolt 802 from the gap between the two Z-shaped rods 2 on the same side, then slide the positioning block 8 out from the cross groove 601, then slide the cutter 7 out from the cross groove 601 and remove it through the gap between the two Z-shaped rods 2, take out the new cutter 7, and the new cutter 7 can be installed and fixed by reversing the operation.

[0031] By connecting the power supply and external switch to the first cylinder 4, the switch of the first cylinder 4 is turned on, and the first cylinder 4 works, causing the connecting block 5 to descend. Under the guidance of the guide rod 9, the connecting block 5 descends, which in turn causes the mounting plate 6 to descend, and then causes the cutter 7 to descend to perform the cutting operation.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, a slot 101 is provided on the top of the worktable 1, and the slot 101 is located directly below the tool 7.

[0033] In this embodiment, the size of the cutting tool 7 is smaller than that of the slot 101, and the cutting tool 7 can completely pass through the slot 101.

[0035] In this embodiment, the convex seat is used to assemble with the mounting plate 6, and the cutter body performs the cutting operation on the cardboard.

[0036] In this embodiment, as Figure 1 As shown, a guide assembly 102 is also provided on the top of the workbench 1. The guide assembly 102 includes a second cylinder, which is fixed on the workbench 1. A guide plate is fixedly connected to the moving end of the second cylinder.

[0037] In this embodiment, there are two guide components 102, located at both ends of the top of the workbench 1. The second cylinder is connected to an external power supply and switch. By starting the second cylinder, the distance between the two guide plates can be changed through the synchronous operation of the two second cylinders, which is suitable for guiding paperboard of different sizes.

[0038] In this embodiment, as Figure 1 As shown, there are two fixing components 10 at the bottom of the mounting plate 6.

[0039] In this embodiment, the guide assembly includes two vertical rods, which are fixed to one side of the bottom of the mounting plate 6. A spring is provided at the bottom of each of the two vertical rods, and a pressure plate is fixedly connected to the bottom of each spring.

[0040] The fixing principle of the fixing component 10 is the same as that of the positioning principle of the cardboard when cutting the cardboard in the prior art (announcement number: CN221517957U), and will not be elaborated on here.
