Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a digital paper slitting mechanism. Background Technology

[0002] The papermaking process is as follows: pulping → beating → forming → drying → creping → winding → base paper → rewinding. Rewinding includes three steps: unwinding the base paper, slitting the base paper, and rewinding the base paper. Slitting a large roll of paper and rewinding it breaks it down into several smaller rolls of the desired size, facilitating subsequent processing into finished products. The most commonly used equipment in the rewinding process is the paper slitting device. Traditional paper slitting equipment is inconvenient to operate, and produces poor slitting results and low quality. Furthermore, existing paper slitting equipment struggles to adjust the slitting width across multiple dimensions, resulting in limited cutting flexibility.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a paper slitting device [CN201510310426.1], which includes a bottom flange and a steel shell cylinder welded to the upper side of the bottom flange. The end of the steel shell cylinder that connects to the bottom flange is necked, and the bottom flange is a closed ring formed by bending and welding steel plates.

[0004] The above solution has solved the problems of inconvenient operation and poor cutting effect of paper cutting equipment in the prior art to a certain extent. However, the solution still has many shortcomings, such as difficulty in adjusting the cutting width in multiple dimensions and poor paper cutting flexibility. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paper digital slitting mechanism, including a feeding platform and a discharging platform, a slitting frame positioned between the feeding platform and the discharging platform, a slitting cavity provided on the slitting frame, a sliding pressing structure provided at one end of the feeding platform near the slitting frame and on both sides of the slitting cavity, a rotating blowing assembly provided inside the slitting frame and at the upper end of the slitting cavity, and a slitting cutter assembly linked to the lower end of the rotating blowing assembly through a lifting structure.

[0007] In the aforementioned paper digital slitting mechanism, the sliding clamping structure includes a limiting part provided at one end of the discharge table, and a sliding adjustment groove arranged in a strip shape is provided on the limiting part. An alignment clamping frame is slidably connected to the sliding adjustment groove through a connecting slider.

[0008] In the aforementioned paper digital slitting mechanism, a telescopic adjustment slider is provided at the bottom of the inner side of the alignment and clamping frame.

One end of the rotating linkage rod is driven by a rotating drive motor set on the outer wall of the slitting frame, and the other end is rotatably set on the slitting frame.

[0011] In the aforementioned paper digital slitting mechanism, the lifting structure includes a horizontally arranged lifting connecting seat. The lower ends of the lifting connecting seat are connected to slitting blade holders via lifting slides on both sides. The lifting connecting seat is equipped with stamping slitting cylinders at both ends. The output ends of the stamping slitting cylinders act on the slitting blade holders and drive the slitting blade holders as a whole to move up and down.

[0015] In the aforementioned paper digital slitting mechanism, a receiving conveyor belt is provided on the discharge platform, corresponding to the outlet of the slitting chamber.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the positioning and clamping frame can achieve flexible adjustment of the clamping position, and it can be used with paper of different widths to ensure stable clamping when cutting paper of different widths; secondly, the adjustment cylinder drives the limit seat to drive the slitting cutter to adjust its height, and the adjustment gap between the lifting connecting seat and the slitting cutter holder provides space and operation basis for adjusting the lateral spacing of the slitting cutter, and the cutter spacing can be flexibly changed according to the needs, directly realizing multi-size adjustment of the slitting width.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-5 As shown, a digital paper slitting mechanism includes a feeding platform 1 and a discharging platform 2. A slitting frame 3 is positioned between the feeding platform 1 and the discharging platform 2. A slitting cavity 31 is provided on the slitting frame 3. A sliding pressing structure 4 is provided on one end of the feeding platform 1 near the slitting frame 3 and on both sides of the slitting cavity 31. A rotating blowing assembly 5 is provided inside the slitting frame 3 and at the upper end of the slitting cavity 31. The lower end of the rotating blowing assembly 5 is linked to a slitting cutter assembly 7 through a lifting structure 6.

[0020] The slitting frame 3 is equipped with a touch screen and control area, which is connected to a control module. The control module is connected to the stamping slitting cylinder 64 and the regulating cylinder 73 for driving.

[0021] The sliding clamping structure 4 includes a limiting part 41 provided at one end of the discharge platform 2. The limiting part 41 is provided with a sliding adjustment groove 42 arranged in a strip shape. The alignment clamping frame 44 is slidably connected in the sliding adjustment groove 42 through a connecting slider 43.

[0022] The alignment and clamping frame 44 can slide laterally along the sliding adjustment groove 42. Combined with the telescopic adjustment slider 45 on the bottom inner side of the alignment and clamping frame 44, it can flexibly clamp and position papers of different widths and thicknesses, ensuring stable feeding.

[0023] As can be seen, a telescopic adjustment slider 45 is provided on the bottom inner side of the alignment and clamping frame 44.

[0024] Obviously, the rotary purging assembly 5 includes a purging rotary plate 51, a plurality of purging air outlets 52 are provided on the lower side of the purging rotary plate 51, and the purging rotary plate 51 is connected to an external air compressor.

[0025] Furthermore, a rotating linkage rod 53 is connected inside the purging rotating plate 51. One end of the rotating linkage rod 53 is driven by a rotating drive motor 54 set on the outer wall of the slitting frame 3, and the other end is rotatably set on the slitting frame 3.

[0026] The rotary blowing assembly 5 drives the rotary linkage rod 53 through the rotary drive motor 54, so that the blowing rotating plate 51 rotates at the upper end of the slitting chamber 31. In conjunction with the blowing air outlet 52 on the lower side of the blowing rotating plate 51, it can blow away paper scraps generated during the slitting process from multiple angles and in all directions, keeping the slitting environment clean.

[0027] Specifically, the lifting structure 6 includes a horizontally arranged lifting connecting seat 61. The lower ends of the lifting connecting seat 61 are connected to the slitting blade holder 63 via lifting slides 62. The lifting connecting seat 61 is provided with stamping slitting cylinders 64 at both ends. The output end of the stamping slitting cylinders 64 acts on the slitting blade holder 63 and drives the slitting blade holder 63 to move up and down as a whole.

[0028] The output force of the stamping slitting cylinders 64 at both ends of the lifting connecting seat 61 acts on the slitting knife holder 63. Combined with the guidance of the lifting sliding grooves 62 on both sides of the lifting connecting seat 61 and the slitting knife holder 63, the slitting knife holder 63 is driven to rise and fall stably as a whole, so as to realize the execution and reset of the slitting action.

[0029] Furthermore, the slitting tool assembly 7 includes a plurality of slitting tools 71 disposed at the lower end of the slitting tool holder 63, and the upper end of the slitting tool 71 is connected to the limiting seat 72 disposed on the upper end surface of the slitting tool holder 63 via a connecting rod.

[0030] More specifically, an adjusting cylinder 73 is provided on the upper end of the lifting connecting seat 61. The output end of the adjusting cylinder 73 is connected to the limiting seat 72 and drives the limiting seat 72 to drive the slitting cutter 71 to adjust its height.

[0031] In detail, there is an adjustable gap 74 between the lifting connecting seat 61 and the slitting knife holder 63.

[0032] When adjusting the paper cutting spacing, the unused slitting cutter 71 is driven to move upward by the adjusting cylinder 73, while the slitting cutter 71 that is in the paper cutting position is retained. The limit seat 72 is used to limit the downward cutting position to ensure that the slitting cutter 71 that needs to cut paper is at the same height.

[0033] The slitting gap is detected by an infrared distance sensor, and the paper cutting width is set by the control module in conjunction with the touch screen.

[0034] Preferably, the discharge platform 2 is provided with a receiving conveyor belt 21 that corresponds to the outlet of the cutting cavity 31.

[0035] In summary, the principle of this embodiment is as follows: the sliding clamping structure 4 achieves stable clamping of different types of paper when they enter the slitting chamber 31 through the sliding adjustment groove 42 and the telescopic adjustment slider 45. Before cutting, the slitting knife assembly 7 uses the adjusting cylinder 73 to drive the unused slitting knife 71 to move upward, retaining the slitting knife 71 in the paper cutting position, thus achieving flexible adjustment of the slitting size. During paper cutting, the lifting structure 6 drives the slitting knife holder 63 to move up and down along the lifting slide 62 through the stamping slitting cylinder 64 to complete the slitting action. After the paper is cut, the rotating blowing assembly 5 removes the paper scraps generated by the slitting with the help of the rotating drive motor 54 and the blowing air hole 52. The receiving conveyor belt 21 transports the slitting paper from the outlet of the slitting chamber 31 to the outside in an orderly manner.
