Description

Technical Field

[0001] This utility model relates to the technical field of electronic device protection, and in particular to a red steel paper cutting machine. Background Technology

[0002] Red steel cardboard, a special paper-based composite insulation material, is widely used in electronics, high-end equipment, and packaging protection. Its processing requires cutting the original board into strips of varying widths or customized blanks according to product specifications. Therefore, red steel cardboard cutting machines are the core equipment for achieving large-scale production in this field. Existing red steel cardboard cutting machines typically employ a multi-blade parallel arrangement structure, achieving multiple cuts through synchronous operation of multiple blades to improve processing efficiency. Due to the diverse applications of red steel cardboard and the frequent changes in the required width specifications of the cut products, the cutting machine must have the ability to flexibly adjust the spacing between the blades.

[0003] However, existing red cardboard cutting machines have the following shortcomings in practical use: Due to the lack of an integrated measuring mechanism, operators need to use specialized measuring tools such as steel rulers and vernier calipers to adjust the spacing between the cutters. During adjustment, one hand must hold the measuring tool close to the cutter, while the other hand slowly moves the cutter, simultaneously observing the scale on the measuring tool and repeatedly fine-tuning the cutter position to achieve the desired cutting width. This process requires simultaneous cutter movement and measuring, which is cumbersome, demanding a high level of operator skill and significantly impacting work efficiency. Furthermore, frequent changes in product width specifications consume considerable debugging time, increasing both time and labor costs. Therefore, this red cardboard cutting machine application is proposed. Utility Model Content

[0019] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0020] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] like Figures 1 to 10As shown, in one embodiment, a red steel cardboard cutting machine 1 includes a worktable 10 and a cutting assembly. A support frame 100 is provided on the worktable 10. The cutting assembly includes a lifting frame 20, a measuring tool 21, a shaft column 22, several clamping blocks 23, and several cutters 24. The lifting frame 20 is slidably mounted on the support frame 100. The measuring tool 21 is mounted on the lifting frame 20. The shaft column 22 is rotatably mounted on the lifting frame 20. Each cutter 24 is coaxially mounted on the shaft column 22 and is spaced apart along the axial direction of the shaft column 22. One end of each clamping block 23 is slidably mounted on the lifting frame 20, and the other end of each clamping block 23 is respectively engaged with each cutter 24. When a cutter 24 is driven by an external force to slide the corresponding clamping block 23 to any position on the lifting frame 20, the clamping block 23 stops at the corresponding scale of the measuring tool 21.

[0024] It should be noted that the support frame 100 tends to be a gantry structure, and it is fixed to the table surface of the worktable 10 by screws; the lifting frame 20 is height-adjustable on the support frame 100, so that the lifting frame 20 can slide relative to the support frame 100 to move closer to or further away from the table surface of the worktable 10. Further, the two ends of the shaft column 22 are rotatably connected to the two ends of the lifting frame 20, and the shaft column 22 and the lifting frame 20 are parallel to each other; each cutter 24 is coaxially sleeved on the shaft column 22, so that each cutter 24 can slide along the axial direction of the shaft column 22, and can rotate about the axis of the shaft column 22; one end of each clamping block 23 is slidably disposed at the upper end of the lifting frame 20 along the axial direction at intervals; the measuring tool 21 is disposed on the side of the lifting frame 20, and the measuring tool 21 is a measuring tool (e.g., a steel ruler), so that when each clamping block 23 slides on the lifting frame 20; each clamping block 23 The sides of each cutter 24 can reciprocate on the surface of the measuring tool 21. Furthermore, the ends of each clamping block 23 that are away from the lifting frame 20 are respectively engaged with each cutter 24. Thus, when each cutter 24 is slid to any position along the axial direction of the shaft column 22 by external force, one cutter 24 will synchronously drive the corresponding clamping block 23 to slide on the lifting frame 20, thereby making the clamping block 23 stop on the corresponding scale of the measuring tool 21. This enables quick adjustment of the interval between any two adjacent cutters 24, reducing unnecessary adjustment actions and adjustment time for different specifications of cutting requirements, thereby improving work efficiency and reducing production costs.

[0025] like Figure 1 , Figure 4 As shown, in one embodiment, the support frame 100 includes a frame body 101 and a screw 102. The frame body 101 is disposed on the workbench 10. One end of the screw 102 is rotatably connected to the lifting frame 20, and the other end of the screw 102 is screwed to the frame body 101.

[0026] It should be noted that the frame 101 includes a top plate 1010, two base blocks 1011, and several uprights 1012. The two base blocks 1011 are fixed to the workbench 10 with screws and are located on opposite sides of the workbench 10. The four corners of the top plate 1010 are fixedly connected to the base blocks 1011 via uprights 1012, making the support frame 100 a gantry structure. Furthermore, one end of the screw 102 is rotatably connected to the middle position of the side of the lifting frame 20 away from the workbench 10, while the other end of the screw 102 passes through the middle position of the top plate 1010 and is screwed to it. Thus, when the screw 102 is rotated by an external force, the lifting position of the lifting frame 20 relative to the uprights 1012 is adjustable, thereby allowing the distance between the lifting frame 20 and the shaft 22 and the workbench 10 to be adjusted.

[0027] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, in one embodiment, the lifting frame 20 includes a horizontal plate 200 and two sliders 201. The two sliders 201 are slidably disposed at both ends of the frame 101. The two ends of the horizontal plate 200 are respectively connected to the two sliders 201. The middle position of the horizontal plate 200 is rotatably connected to the screw 102. The two ends of the shaft column 22 are rotatably connected to the two sliders 201.

[0028] It should be noted that two uprights 1012 are provided on one base block 1011, and both ends of one slider 201 are slidably mounted on the two uprights 1012 on one base block 1011. Correspondingly, both ends of another slider 201 are slidably mounted on the two uprights 1012 on another base block 1011. Furthermore, both ends of the shaft 22 are rotatably connected to the sides of the two sliders 201 that are close to each other, so that the shaft 22 can rotate relative to the two sliders 201. Furthermore, both ends of the horizontal plate 200 are fixedly connected to the sides of the two sliders 201 that are away from the worktable 10 through two cylinders, so that there is a gap between the horizontal plate 200 and the sides of the sliders 201 that are close to each other, and this gap is greater than the radius of the cutter 24. Thus, when each cutter 24 is coaxially mounted on the shaft 22, the blade of each cutter 24 cannot abut against the horizontal plate 200, so that each cutter 24 can rotate around the axis of the shaft 22.

[0029] like Figure 1 , Figure 2 , Figures 4 to 9 As shown, in one embodiment, a slide rail 2000 is provided on the horizontal plate 200, and a sliding groove 230 and a slot 231 are provided on the clamping block 23. The sliding groove 230 is engaged with the slide rail 2000, and the slot 231 is engaged with the cutter 24.

[0030] It should be noted that a raised slide rail 2000 is provided on the top surface of the horizontal plate 200 near the top plate 1010, and the slide rail 2000 is close to the side of the horizontal plate 200, with both ends extending to the end faces of the horizontal plate 200 near the two sliders 201; furthermore, a groove 230 is provided on one end of the clamping block 23, and the groove 230 slides and engages with the slide rail 2000 on the horizontal plate 200, so that each clamping block 23 can slide along the axial direction of the horizontal plate 200; furthermore, since the horizontal plate 200 and the shaft column 22 are parallel to each other... The cutter 24 is sleeved on the shaft post 22, so that the radial surface of the cutter 24 is perpendicular to the extension direction of the slide rail 2000. Therefore, a slot 231 is provided on the end face of the clamping block 23 away from the horizontal plate 200, and the extension direction of both ends of the slot 231 is perpendicular to the extension direction of the slide rail 2000, so that the slot 231 can engage with the cutter 24 perpendicular to the shaft post 22. The width of the slot 231 is adapted to the thickness of the cutter 24, so that when the slot 231 engages with the cutter 24, the cutter 24 can drive the clamping block 23 to slide precisely under the push of external force.

[0031] In one embodiment, two raised slide rails 2000 are provided on the top surface of the horizontal plate 200 near the top plate 1010. The two slide rails 2000 are respectively close to two opposing sides of the top surface of the horizontal plate 200, and the two ends of the two slide rails 2000 extend to the end faces of the horizontal plate 200 near the two sliders 201. Further, the clamping block 23 tends to be C-shaped, and a sliding groove 230 is provided on both ends of the clamping block 230. The two sliding grooves 230 are respectively slidably engaged with the two slide rails 2000, so that the clamping block 23 can slide stably on the horizontal plate 200. Further, when the two ends of the clamping block 23 are slidably engaged with the horizontal plate 200, the middle position of the clamping block 23 protrudes relative to the horizontal plate 200 towards the shaft 22. The slot 231 is located in the middle of the clamping block 23 and extends from the end of the clamping block 23 away from the horizontal plate 200 toward the slide groove 230. The two ends of the slot 231 pass through both sides of the clamping block 23, so that the end face of the clamping block 23 near the cutter 24 forms a U-shaped structure that engages with the cutter 24. From the axial direction of the cutter 24, the clamping block 23 will be tangential to the cutter 24. In this way, when the operator pushes the cutter 24 to slide relative to the shaft 22, the clamping block 23 can be more stably driven to slide relative to the horizontal plate 200. The width of the slot 231 is adapted to the thickness of the cutter 24, thereby improving the accuracy of the clamping block 23 stopping at the scale position on the measuring tool 21.

[0032] like Figure 1 , Figure 2 , Figures 4 to 9As shown, in one embodiment, a ruler groove 2001 is also provided on the horizontal plate 200, and the measuring tool 21 is disposed in the ruler groove 2001.

[0033] It should be noted that a ruler groove 2001 is provided on the side of the horizontal plate 200. One side of the ruler groove 2001 is connected to the bottom surface of the horizontal plate 200 near the shaft column 22, and both ends of the ruler groove 2001 are connected to the end surfaces of the horizontal plate 200 near the two sliders 201 respectively. Furthermore, the depth of the ruler groove 2001 is adapted to the thickness of the measuring tool 21, so that when the measuring tool 21 is fixed in the ruler groove 2001 by screws, the surface of the measuring tool 21 with the scale is on the same plane as the side of the horizontal plate 200, so as to avoid the measuring tool 21 from affecting the sliding of the clamping block 23 due to protrusion.

[0034] like Figure 1 , Figure 2 , Figures 4 to 7 , Figure 10 As shown, in one embodiment, an indicator 2310 is provided on the inner bottom wall of the slot 231. The indicator 2310 is aligned with the ruler slot 2001 and is used to read the scale on the measuring tool 21.

[0035] It should be noted that, since the clamping block 23 has a C-shaped structure, for ease of description, the bottom and two sides of the clamping block 23 are respectively defined as the bottom rod 232, the first side rod 233, and the second side rod 234. The two ends of the bottom rod 232 are connected to the first side rod 233 and the second side rod 234 respectively. A sliding groove 230 is provided on the side surface of the first side rod 233 and the side surface of the second side rod 234 that is furthest from the bottom rod 232 and closest to each other, so that the first side rod 233 and the second side rod 234 together drive the bottom rod 232 to slide on the horizontal plate 200; furthermore, the bottom rod 232 furthest from the first side rod 233 / A slot 231 is provided on one side surface of the second side rod 234, and the inner bottom wall of the slot 231 extends into the first side rod 233 and the second side rod 234. When the first side rod 233 and the second side rod 234 are slidably engaged with the horizontal plate 200, the slot 231 extends relative to the clamping block 23 to a position aligned with the measuring tool 21. The indicator part 2310 is provided on the inner bottom wall of the slot 231, and the indicator part 2310 extends inward from the middle of the inner bottom wall to form a pointed structure. When the slot 231 is engaged with the cutter 24, the pointed position of the indicator part 2310 is aligned with the blade of the cutter 24. Since the inner bottom wall of the slot 231 is aligned with the measuring tool 21, when it is necessary to adjust the interval between each cutter 24, the operator can slide the cutter 24 along the axial direction of the shaft column 22 and read the scale on the measuring tool 21 through the sharp corner position on the indicator 2310, thereby achieving precise adjustment of the interval distance between each cutter 24.

[0036] It should be noted that a circular hole 2330 is provided on the first side rod 233, and a threaded structure is provided on the inner side wall of the circular hole 2330; a side groove 2002 is provided on the side surface of the horizontal plate 200 near the first side rod 233; in one embodiment, the first side rod 233 is screwed into the circular hole 2330 by screws and extends into the side groove 2002 to abut against its inner bottom wall; in this way, when the cutter 24 drives the clamping block 23 to slide to the position to be adjusted, the clamping block 23 can be locked to the horizontal plate 200 by tightening the screws.

[0037] like Figure 1 , Figure 2 , 4 to Figure 7 As shown, in one embodiment, the cutter 24 includes a blade 240 and a blade holder 241. The blade holder 241 is sleeved on the shaft post 22, and the blade 240 is coaxially disposed on the blade holder 241. The slot 231 engages with the blade 240.

[0038] It should be noted that the tool holder 241 has a ring-shaped structure, and the blade 240 also has a ring-shaped structure. The tool holder 241 is fitted onto the shaft 22, and the blade 240 is also fitted onto the shaft 22. The blade 240 is fixedly connected to the side of the tool holder 241 by screws, so that the axis of the blade 240 can be kept coincident with the axis of the shaft 22, and the blade 240 and the tool holder 241 can rotate synchronously. Furthermore, a fixing hole is opened on the circumferential surface of the tool holder 241, and a groove 220 is opened along the axial direction on the outer wall of the shaft 22. The operator screws the screw into the fixing hole from one end near the outer wall of the tool holder 241 and out from the other end of the fixing hole to extend into the groove 220. It should be noted that the width of the groove 220 is adapted to the diameter of the screw. In this way, the tool holder 241 cannot drive the blade 240 to rotate relative to the shaft 22. Similarly, each blade holder 241 is screwed into a fixing hole and abuts against the inner bottom wall of the groove 220, so that when the shaft 22 rotates, it can drive each cutting blade 24 to rotate synchronously. Furthermore, when the operator needs to adjust the spacing between the blades 240, by loosening the screws so that the end face of the screws is away from the inner bottom wall of the groove 220, the operator can manually push the blade holder 241 to make the blades 240 slide against the shaft 22 for adjustment.

[0039] like Figure 1 , Figure 4 As shown, in one embodiment, the cutting assembly further includes a carrier plate 25 and a drive member 26. The carrier plate 25 is slidably disposed on the worktable 10, and the drive member 26 is disposed on the worktable 10. The output shaft of the drive member 26 is connected to the carrier plate 25, and the carrier plate 25 is used to carry the red steel cardboard.

[0040] It should be noted that the drive component 26 is a push cylinder structure. The drive component 26 is set on the table surface of the worktable 10. The material plate 25 slides on the table surface of the worktable 10 through the guide rail, and the upper surface of the material plate 25 is perpendicular to the sliding direction of the lifting frame 20. Furthermore, the output shaft of the drive component 26 is connected to the side of the material plate 25 away from the shaft column 22, so that the drive component 26 can drive the material plate 25 to slide closer to or away from the shaft column 22, thereby causing the material plate 25 to drive the red steel paperboard closer to or away from each blade 240. Specifically, when the drive unit 26 drives the carrier plate 25 to slide towards the shaft column 22, and the carrier plate 25 completely passes the shaft column 22, the operator rotates the screw 102 to make the horizontal plate 200 slide downward. The horizontal plate 200 will drive the shaft column 22 downward through the two sliders 201, and at the same time, the shaft column 22 will drive the blades 240 on each blade holder 241 to approach the carrier plate 25. With the continuous pushing of the drive unit 26, each blade 240 can simultaneously cut the red cardboard. Furthermore, in actual operation, the operator can also rotate the screw 102 to make each cutter 24 move downward towards the carrier plate 25, thereby adjusting the cutting depth of each cutter 24 on the red cardboard to meet different cutting needs.

[0041] It should be noted that two baffles 250 are respectively provided on the upper surface of the carrier plate 25 along the sliding direction, and the two baffles 250 are located near the two ends of the carrier plate 25 close to the two bottom blocks 1011, to prevent the red steel cardboard from sliding off the sides of the carrier plate 25 or shifting during the cutting process, thereby ensuring the stability of the cutting; furthermore, two top blocks 251 are also provided on the carrier plate 25, both of which are located on the upper surface of the carrier plate 25, and one of the two top blocks 251 is positioned close to the bottom block 1011. Each side is connected to one end of two baffles 250. When the red steel cardboard is placed on the carrier plate 25, the two top blocks 251 push the red steel cardboard away from the end face of each cutter 24. This ensures that when the drive member 26 pushes the carrier plate 25, the carrier plate 25 can keep the red steel cardboard close to each cutter 24, so as to prevent the red steel cardboard from sliding out from the end face of the carrier plate 25 close to the drive member 26 when the red steel cardboard is pushed by each cutter 24, thereby further improving the cutting stability.

[0042] like Figure 1 , Figure 2 , Figure 4 , Figures 6 to 8 As shown, in one embodiment, the support frame 100 further includes two guide rods 1013, one end of each guide rod 1013 is connected to the horizontal plate 200, and the other end of each guide rod 1013 passes through the support frame 100.

[0043] It should be noted that one end of the two guide rods 1013 is fixedly connected to the top surface of the horizontal plate 200 near the top plate 1010, and the two guide rods 1013 are located on both sides of the screw 102, while the other end of the two guide rods 1013 passes through the top plate 1010. This improves the smoothness of the sliding of the horizontal plate 200 relative to the frame 101, improves the parallelism between the shaft column 22 and the worktable 10, and further improves the consistency of the cutting depth of each blade 240 during the cutting process.

[0044] like Figure 1 , Figure 4 As shown, in one embodiment, the cutting assembly further includes a handwheel 27, which is disposed on the end of the screw 102 away from the horizontal plate 200, and is used to drive the screw 102 to rotate.

[0045] It should be noted that a handwheel 27 is coaxially mounted on the end of the screw 102 away from the horizontal plate 200, and a rotatable cap is provided on the edge of the side of the handwheel 27 away from the screw 102. In this way, the operator can rotate the handwheel 27 by rotating the cap, which in turn quickly rotates the screw 102, thereby improving the convenience of adjustment.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
