Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, and more specifically, to a cutting machine device. Background Technology

[0002] With the development of technology and the continuous improvement of industrial automation, new paper cutting machines are gradually replacing traditional manual cutting methods. Paper cutting machines can cut various types of paper, such as craft paper, packaging boxes, book covers, and self-adhesive labels, offering higher quality and processing efficiency than manual cutting.

[0003] Existing paper cutting machines cut paper by having a blade mounted on the machine head slice through it. The primary drive mechanism is a cylinder. To adapt the blade to paper of varying thicknesses, the height of both the cylinder and the blade needs to be adjusted. However, existing adjusting cylinders have a relatively simple structure and are prone to wobbling, especially during cutting when vibrations can cause them to loosen, further destabilizing the cylinder and blade positions. Summary of the Invention

[0004] The problem solved by this invention is that the structure of the regulating cylinder of the existing cutting machine is relatively simple and prone to shaking. Especially during the cutting process, the vibration can cause the structure of the regulating cylinder to loosen, which in turn makes the position of the cylinder and the cutter head more unstable.

[0005] To address the above problems, the present invention proposes the following technical solution:

[0006] A cutting machine device includes a mounting plate, a cylinder structure, and a height adjustment assembly. A first fixed plate and a sliding frame are arranged sequentially from bottom to top on one side of the mounting plate. The first fixed plate is fixed to the side wall of the mounting plate, and the sliding frame is slidably connected to the side wall of the mounting plate in a vertical direction. The cylinder structure is mounted on the sliding frame, and the height adjustment assembly is installed between the first fixed plate and the sliding frame.

[0007] The height adjustment assembly includes a locking screw, a rotating sleeve, a rotating rod, and a limiting rod. A rotating hole is provided through the first fixed plate, and a threaded hole is provided through the sliding frame. The locking screw passes through the rotating hole and is rotatably connected to the rotating hole, and the locking screw passes through the threaded hole and is threadedly connected to the threaded hole.

[0008] The lower end of the locking screw has a rotating groove on its outer peripheral wall, and the lower end of the locking screw is fitted with the rotating sleeve. The inner wall of the rotating sleeve is provided with a rotating groove for insertion and matching with the rotating groove. The lower end face of the first fixing plate has a plurality of limiting grooves evenly spaced along the circumferential direction of the locking screw, and the upper end of the rotating sleeve is provided with a limiting rod for insertion and matching with the limiting groove.

[0009] The cutting machine device provided by this invention, compared with the prior art, has, but is not limited to, the following advantages:

[0010] Beneficial effects:

[0011] Under normal conditions, the limiting rod of the rotating sleeve is inserted into the limiting groove. When it is necessary to adjust the height of the cylinder structure and the cutter assembly connected to the lower end of the cylinder structure, firstly, the rotating sleeve is moved downwards, causing the limiting rod to disengage from the limiting groove, while the rotating rod enters the rotating groove. Then, the rotating sleeve is rotated, causing the rotating rod to rotate. Since the rotating rod is engaged with the rotating groove, it in turn causes the locking screw to rotate. Because the first fixed plate has a through-hole and the sliding frame has a through-hole, the locking screw passes through the through-hole and is rotatably connected to the through-hole. The locking screw also passes through the through-hole and is threadedly connected to the through-hole. That is, when the locking screw rotates in the through-hole, the locking screw does not undergo axial displacement, while the sliding frame moves on the locking screw through the through-hole. Thus, the sliding frame, the cylinder structure mounted on the sliding frame, and the cutter assembly connected to the lower end of the cylinder structure move axially along the locking screw without rotating, thereby adjusting the height of the cylinder structure and the cutter assembly to adapt to the thickness of the paper. After adjustment, move the rotating sleeve upward so that the limiting rod is inserted into the limiting groove, so that the rotating sleeve will no longer rotate. This prevents the rotating sleeve from loosening or rotating due to vibration, which could cause instability in the cylinder structure and cutter head assembly.

[0012] Preferably, the locking screw includes a screw body, a screw head, and a limiting ring. The screw body passes through the rotating hole and the threaded hole.

The meanings of the Z-axis, X-axis, and Y-axis are only for the convenience of describing the present invention and simplifying the description, and are not intended to 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 the present invention.

[0036] See Figures 1-8The present invention provides a cutting machine device, comprising a mounting plate 1, a cylinder structure 2, and a height adjustment assembly 3. A first fixing plate 11 and a sliding frame 12 are sequentially arranged from bottom to top on one side of the mounting plate 1. The first fixing plate 11 is fixed to the side wall of the mounting plate 1, and the sliding frame 12 is slidably connected to the side wall of the mounting plate 1 in a vertical direction. The cylinder structure 2 is mounted on the sliding frame 12, and the height adjustment assembly 3 is installed between the first fixing plate 11 and the sliding frame 12. The height adjustment assembly 3 includes a locking screw 31, a rotating sleeve 32, a rotating rod 33, and a limiting rod 34. A rotating hole 110 is provided through the first fixing plate 11, and a cylinder structure 2 is provided through the sliding frame 12. The locking screw 31 passes through the threaded hole 120 and is rotatably connected to the rotating hole 110. The locking screw 31 also passes through the threaded hole 120 and is threadedly connected to it. A rotating groove 311 is provided on the outer peripheral wall of the lower end of the locking screw 31. A rotating sleeve 32 is fitted onto the lower end of the locking screw 31. A rotating 33 is provided on the inner wall of the rotating sleeve 32 for insertion and matching with the rotating groove 311. A plurality of limiting grooves 14 are evenly spaced along the circumferential direction of the locking screw 31 on the lower end face of the first fixing plate 11. A limiting rod 34 is provided on the upper end of the rotating sleeve 32 for insertion and matching with the limiting grooves 14.

[0037] Specifically, a movable hole is provided through the first fixed plate 11, and the piston rod 20 of the cylinder structure 2 is used to pass through the movable hole; the movable hole facilitates the piston rod 20 of the cylinder structure 2 to perform cutting and pressing work.

[0038] The cylinder structure 2 is further provided with a housing, which serves to prevent dust and dirt from entering the cylinder structure 2.

[0039] In this embodiment, under normal conditions, the limiting rod 34 of the rotating sleeve 32 is inserted into the limiting groove 14. The mounting plate 1 and the first fixing plate 11 are configured to provide a mounting carrier for the locking screw 31. When it is necessary to adjust the height of the cylinder structure 2 and the cutter head assembly 7 connected to the lower end of the cylinder structure 2, the insertion relationship between the limiting rod 34 of the rotating sleeve 32 and the limiting groove 14 can be released first. Then, through the insertion relationship between the rotating rod 33 and the rotating groove 311, the rotating sleeve 32 can be used to adjust the height of the cylinder structure 2 and the cutting head assembly 7 connected to the lower end of the cylinder structure 2. 2. The locking screw 31 is rotated, thereby enabling the sliding frame 12, cylinder structure 2, and cutter head assembly 7 to move up and down through the threaded connection between the locking screw 31 and the sliding frame 12. Specifically, for example, the rotating sleeve 32 is first moved downwards, causing the limiting rod 34 to disengage from the limiting groove 14, while the rotating rod 33 enters the rotating groove 311. Then, the rotating sleeve 32 is rotated, causing the rotating rod 33 to rotate. Since the rotating rod 33 is connected to the rotating groove 311, the cylinder structure 2 and the cutter head assembly 7 can move up and down through the threaded connection between the locking screw 31 and the sliding frame 12. The 11-phase engagement causes the locking screw to rotate. Since the first fixing plate 11 has a through-hole 110 and the sliding frame 12 has a through-hole 120, the locking screw 31 passes through the through-hole 110 and is rotatably connected to it. Furthermore, the locking screw 31 passes through the threaded hole 120 and is threadedly connected to it. Thus, rotating the locking screw 31 drives the sliding frame 12 onto the locking screw 31. The sliding frame 12, the cylinder structure 2 mounted on the sliding frame 12, and the cutter head assembly 7 connected to the lower end of the cylinder structure 2 move axially along the locking screw 31 without rotation. This adjusts the height of the cylinder structure 2 and the cutter head assembly 7 to accommodate the paper thickness. The rotating hole 110 limits the rotation of the locking screw 31, preventing radial displacement during the drive process and ensuring stability. After adjustment, the rotating sleeve 32 is moved upward, causing the limiting rod 34 to insert into the limiting groove 14, preventing further rotation of the rotating sleeve 32. This prevents the rotating sleeve 32 from loosening or rotating due to vibration, which could cause instability in the cylinder structure 2 and the cutter head assembly 7.

[0040] Specifically, the lower side wall of the rotating sleeve 32 is provided with an operating hole 320, which is used to insert a wrench to extend the lever arm, so that the user can rotate the rotating sleeve 32 and the locking screw 31 by rotating the wrench, saving time and effort.

[0041] The sliding frame 12 slides vertically and is located above the first fixed plate 11. The vertical direction is shown as the Z-axis direction in the figure.

[0042] See Figures 5-6 Preferably, the locking screw 31 includes a screw body 313, a screw head 314, and a limiting ring 315. The screw body 313 passes through the rotating hole 110 and the threaded hole 120. The limiting ring 315 is fixedly sleeved on the outside of the screw body 313 and integrally formed with the screw body 313. The screw head 314 is fixed to one end of the screw body 313 by a screw, and the diameter of the screw head 314 is larger than the diameter of the screw body 313. When the screw body 313 is rotatably connected to the rotating hole 110, the limiting ring 315 and the screw head 314 abut against the upper and lower end faces of the first fixing plate 11, respectively.

[0043] Specifically, a washer groove is provided on the upper end face of the first fixing plate 11 outside the rotating hole 110, and a rubber washer is installed in the washer groove. When the screw body 313 is rotatably connected to the rotating hole 110, the limiting ring 315 and the screw head 314 abut against the upper and lower end faces of the first fixing plate 11, respectively, and the limiting ring 315 contacts the rubber washer. The rubber washer is provided to reduce frictional damage between the limiting ring 315 and the first fixing plate 11, and also helps to ensure that the screw body 313 rotates with a certain amount of friction, avoiding inaccurate adjustment due to too easy rotation.

[0044] In this embodiment, the setting of the limiting ring 315 and the screw head 314 increases the convenience of installing the locking screw 31, as the screw head 314 can be removed for installation. On the other hand, it helps to restrict the axial displacement of the screw body 313, thereby allowing the sliding frame 12 to move.

[0045] See Figures 5-6 Preferably, the height adjustment assembly 3 further includes a limiting spring 38, the outer wall of the screw head 314 is provided with a mounting groove 312, and the limiting spring 38 is sleeved in the mounting groove 312 of the screw head 314; the rotating sleeve 32 is sleeved on the outside of the screw head 314 and the upper end of the rotating sleeve 32 is connected to the upper end of the limiting spring 38.

[0046] Specifically, the limiting spring 38 is sleeved on the outside of the screw head 314 and located in the mounting groove 312; the inner diameter of the rotating sleeve 32 is larger than the diameter of the screw head 314, the rotating sleeve 32 is sleeved on the outside of the screw head 314, the top end of the rotating sleeve 32 has an upper ring cover, and the upper end of the limiting spring 38 abuts against the lower end face of the upper ring cover.

[0047] In this embodiment, under normal conditions, the limiting spring 38 abuts against the rotating sleeve 32, causing the rotating sleeve 32 to be located at the upper end of the screw head 314, that is, the limiting rod 34 is inserted into the limiting groove 14. When it is necessary to adjust the height of the cylinder structure 2 and the cutter head assembly 7 connected to the lower end of the cylinder structure 2, firstly, the rotating sleeve 32 is pressed against the limiting spring 38 to move downward, causing the limiting rod 34 to disengage from the limiting groove 14, and at the same time, the rotating rod 33 enters the rotating groove 311. Then, the rotating sleeve 32 is rotated, and the rotating sleeve 32 drives the rotating rod 33 to rotate, thereby driving the locking screw to rotate, realizing the movement of the sliding frame 12. After adjustment, the rotating sleeve 32 is moved upward so that the limiting rod 34 is inserted into the limiting groove 14. The rotating sleeve 32 will no longer rotate. In addition, the limiting spring 38 ensures that the limiting rod 34 will not easily fall out of the limiting groove 14, further preventing the rotating sleeve 32 from loosening or rotating due to vibration.

[0048] See Figures 2-3 Preferably, the rotating groove 311 is disposed on the outer peripheral wall of the screw head 314 and penetrates the upper edge of the screw head 314 to form an opening, and the limiting rod 34 is used to enter the rotating groove 311 from the opening.

[0049] Specifically, the rotating groove 311 includes a horizontal groove and a vertical groove, which together form an inverted "T" shape. The upper end of the vertical groove passes through the upper edge of the screw head 314 to form the opening.

[0050] In this embodiment, when the rotating sleeve 32 moves downward, the rotating rod 33 enters the vertical groove from the opening and then enters the horizontal groove. When the rotating rod 33 rotates with the rotating sleeve 32, the rotating rod 33 engages with the rotating groove 311 at the horizontal groove, thereby driving the screw head 314 and the screw body 313 to rotate together. The horizontal groove and the vertical groove of the rotating groove 311 can prevent the rotating rod 33 from easily falling out of the rotating groove 311. After adjustment, the rotating sleeve 32 needs to be rotated in the opposite direction of rotation so that the rotating rod 33 rotates to face the vertical groove, and then the rotating sleeve 32 is moved upward so that the rotating rod 33 disengages from the vertical groove and the opening.

[0051] See Figure 4Preferably, the cutting machine device further includes a slide rail 4, and the slide rail 4 is fixed vertically on the mounting plate 1 facing the side wall of the first fixing plate 11 and located above the first fixing plate 11; one end of the sliding frame 12 is provided with a first sliding groove, and the sliding frame 12 is slidably connected to the slide rail 4 through the first sliding groove.

[0052] Specifically, a limiting plate is provided at the upper end of the slide rail 4. After the sliding frame 12 is installed on the slide rail 4 through the first slide groove, the limiting plate is installed at the top of the slide rail 4 to restrict the sliding frame 12 from detaching from the slide rail 4.

[0053] In this embodiment, the slide rail 4 and the first slide groove are arranged so that the sliding frame 12 moves along the slide rail 4 when it moves. On the one hand, this helps to ensure that the sliding frame 12 moves under the rotation of the screw body 313 without rotating. On the other hand, it helps to ensure that the sliding frame 12 moves more smoothly without being misaligned.

[0054] See Figures 4-6 Preferably, the height adjustment assembly 3 further includes an adjusting plate 35, a mounting screw 36, and a stress-relieving screw 37. The adjusting plate 35 has a through mounting screw hole 350, and the adjusting plate 35 is mounted on the screw body 313 through the mounting screw hole 350 and located on the upper end face of the sliding frame 12. The mounting screw 36 is used to fix the adjusting plate 35 to the sliding frame 12. The adjusting plate 35 has a stress-relieving screw hole, and the stress-relieving screw 37 is used to be installed in the stress-relieving screw hole, with the lower end face of the stress-relieving screw 37 abutting against the upper end face of the sliding frame 12.

[0055] In this embodiment, in order to eliminate the return gap between the screw body 313 and the threaded hole 120 of the sliding frame 12 during punching of the cylinder structure 2 and improve the punching accuracy, an adjusting plate 35 is provided above the sliding frame 12. The adjusting plate 35 is screwed onto the screw body 313 through the mounting screw hole 350. After adjusting the relative position between the adjusting plate 35 and the sliding frame 12, the adjusting plate 35 is fixed onto the sliding frame 12 by the mounting screw 36. At this time, the gaps between the screw body 313 and the sliding frame 12, and between the screw body 313 and the adjusting plate 35 are all zero. However, due to the tightening force of the mounting screw 36, the screw body 313 cannot rotate easily. To solve this problem, two unloading screw holes are provided on the adjusting plate 35. The unloading screw 37 is installed in the unloading screw hole, and the lower end face of the unloading screw 37 abuts against the upper end face of the sliding frame 12. This adjusts the tightening force of the unloading screw 37 to counteract the tightening force of the mounting screw 36. In this way, the screw body 313 can rotate more easily, and the mounting screw 36 can also be prevented from loosening.

[0056] See Figure 5 and Figure 7 Preferably, the height adjustment assembly 3 further includes a floating joint 5, a mating shaft 6, and a cutter head assembly 7. The lower end of the piston rod 20 of the cylinder structure 2 is connected to the mating shaft 6 through the floating joint 5, and the lower end of the mating shaft 6 is connected to the cutter head assembly 7.

[0057] In this embodiment, the floating joint 5 is configured to connect the mating shaft 6 and the piston rod 20, so that when adjusting the height of the sliding frame 12 and the cylinder structure 2, the blade assembly 7 is moved to adjust the height of the blade assembly 7 to adapt to the thickness of the paper.

[0058] See Figure 7 Preferably, the floating joint 5 includes a floating sleeve 51, a connecting sleeve 52, a connecting bolt 53, and a shock-absorbing pad 54. The floating sleeve 51 is fixedly connected to the connecting sleeve 52, and the connecting bolt 53 is threadedly connected to the connection point inside the floating sleeve 51 and the connecting sleeve 52. A radial gap is provided between the connecting bolt 53 and the inner wall of the floating sleeve 51. The lower end of the piston rod 20 of the cylinder structure 2 is inserted and fixed inside the floating sleeve 51, and the shock-absorbing pad 54 is used to be installed between the piston rod 20 and the connecting bolt 53.

[0059] In this embodiment, when the piston rod 20 of the cylinder structure 2 moves up and down in a linear motion, the shock-absorbing pad 54 has a shock-absorbing effect; if there is a slight deviation between the axis of the piston rod 20 and the axis of the mating shaft 6, it can be compensated by the radial clearance between the connecting bolt 53 and the floating sleeve 51, thereby avoiding jamming and ensuring that the cutter head assembly 7 can cut smoothly.

[0060] See Figure 7 Preferably, a second fixing plate 13 is fixedly connected to one side of the mounting plate 1 below the first fixing plate 11, and a mounting hole 130 is provided through the second fixing plate 13; the cutting machine device further includes an angle adjustment component 8, which includes a limiting sleeve 81 and a slider 82. The limiting sleeve 81 is used to be installed in the mounting hole 130, and the slider 82 is fixed to the inner wall of the limiting sleeve 81; a second sliding groove 60 is provided on the side wall of the mating shaft 6, and the mating shaft 6 is used to pass through the inner ring of the limiting sleeve 81 and the slider 82 is used to slide in connection with the second sliding groove 60.

[0061] In this embodiment, the mating shaft 6 passes through the inner ring of the limiting sleeve 81, and the slider 82 is slidably connected to the second sliding groove 60. On the one hand, this allows the slider 82 to move along the second sliding groove 60 when the cutter head assembly 7 and the mating shaft 6 move, thus providing a guiding function and preventing the mating shaft 6 and the cutter head assembly 7 from becoming misaligned during movement. On the other hand, it also provides reinforcement, making the mating shaft 6 more stable when moving up and down, which helps to reduce vibration.

[0062] See Figure 7 Preferably, the angle adjustment assembly 8 further includes a first bearing 84, a second bearing 85, and an adjustment structure 83 for adjusting the rotation of the mating shaft 6. The upper end of the mating shaft 6 is connected to the first bearing 84, and the connecting sleeve 52 of the floating joint 5 is sleeved on the outside of the first bearing 84. The limiting sleeve 81 is rotatably installed inside the mounting hole 130 through the second bearing 85.

[0063] Specifically, the adjustment structure 83 includes a motor 831, an adjustment cylinder 832, and a timing belt 833. The adjustment cylinder 832 is fixedly sleeved on the outside of the limiting sleeve 81, and the timing belt 833 is connected between the output shaft of the motor 831 and the adjustment cylinder 832.

[0064] In this embodiment, when the motor 831 is working, the output shaft of the motor 831 rotates, driving the adjusting cylinder 832 and the mating shaft 6 to rotate via the synchronous belt 833, thereby adjusting the rotation of the cutter head assembly 7. This facilitates adjusting the angle of the cutter head assembly 7 to cut different shapes. When the mating shaft 6 rotates, its upper end is connected to the floating joint 5 via the first bearing 84, without affecting the rotation and movement of the mating shaft 6. The limiting sleeve 81 also rotates via the second bearing 85, without affecting the sliding fit between the slider 82 and the second slide groove 60.

[0065] See Figure 8 Preferably, the cutter head assembly 7 includes a cutter sleeve 71, a mounting block 72, a punch 73, a pressure foot spring 74, a pressure foot inner shell 75, and a pressure foot outer shell 76. The cutter sleeve 71 is fixed to the lower end of the mating shaft 6 by screws. The mounting block 72 is fixed inside the cutter sleeve 71. The punch 73 is inserted into the lower end of the mounting block 72 and fixed by screws. The pressure foot inner shell 75 is fixed to the outside of the cutter sleeve 71. The lower end of the pressure foot inner shell 75 is provided with an inner shell hole. The punch 73 extends through the inner shell hole to the lower end of the pressure foot inner shell 75. The pressure foot outer shell 76 is sleeved on the lower end of the pressure foot inner shell 75. The lower end of the pressure foot outer shell 76 is provided with an outer shell hole that matches the punch 73. The pressure foot spring 74 is connected between the outer bottom surface of the pressure foot inner shell 75 and the inner bottom surface of the pressure foot outer shell 76.

[0066] See Figure 8 Specifically, the cutter head assembly 7 further includes a retaining ring 77 and a retaining protrusion 78. The outer wall of the presser foot inner shell 75 is provided with a groove. The retaining ring 77 is installed in the groove and partially protrudes from the groove. The retaining protrusion 78 is fixed to the inner wall of the presser foot outer shell 76. When the presser foot outer shell 76 is sleeved on the lower end of the presser foot inner shell 75, the retaining protrusion 78 is engaged with the upper surface of the portion of the retaining ring 77 that protrudes from the groove.

[0067] In this embodiment, the punch 73 rises after cutting, carrying paper and other materials. The arrangement of the pressure foot spring 74 and the pressure foot housing 76 facilitates the falling of the paper and other materials. When the cutter assembly 7 falls to cut, the pressure foot housing 76 first contacts the paper, then compresses the pressure foot spring 74, causing the pressure foot housing 76 to move upward relative to the inner pressure foot housing 75. This causes the punch 73 to extend from the housing hole and cut the paper. After cutting, the cylinder structure 2 drives the cutter assembly 7 to move upward. As the punch 73 moves upward, the pressure foot housing 76 is continuously pressed against the paper surface by the restoring force of the pressure foot spring 74 until the punch 73 completely detaches from the paper and retracts into the pressure foot housing 76. The pressure foot housing 76 pushes the paper off the punch 73, separating the paper from the punch 73 and preventing the paper from being carried along and affecting the next cut.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
