Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of paper cutters, and more specifically, to a paper cutting device and method for multi-station synchronous cutting. Background Art

[0002] A paper cutter is a machine used to meet the paper cutting requirements in the late stage of printing. A stack of papers is placed on the platform of the paper cutter. Through the paper pushing system on the paper cutter, the position of the papers is limited. Then, the paper pressing device presses the papers, and the cutting knife device cuts the papers. After that, the papers are manually rotated on the platform to turn the uncut side towards the cutting knife device. The paper pushing system will change the pushing distance according to the vertical and horizontal widths of the papers, so as to complete the cutting of multiple edges of the papers at one time.

[0003] Most existing paper cutters are equipped with a relatively long cutting knife device and a paper pushing system of the same width. However, most of the papers to be cut are less than half the length of the cutting knife. A worker performs the operations of rotating and aligning the papers. During cutting, a large part of the cutting edge on the cutting knife does not cut the papers, resulting in low utilization rate of the device. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide a paper cutting device and method for multi-station synchronous cutting, which are used to solve the technical problem that the utilization rate of the paper cutter is sometimes low in the prior art when cutting papers.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a paper cutting device for multi-station synchronous cutting, including a machine base, an operation platform, a paper pushing platform and a tool rest. The operation platform, the paper pushing platform and the tool rest are all fixedly installed on the machine base. The operation platform and the paper pushing platform are respectively arranged on both sides of the tool rest. A cutting knife device is arranged on the tool rest. The paper cutting device further includes a paper pushing frame, a paper pushing mechanism and a C-shaped separator. The paper pushing frame is slidably arranged on the paper pushing platform. The paper pushing mechanism is fixedly connected to the paper pushing frame. The paper pushing mechanism is used to respectively push and limit papers of multiple different sizes. The paper pushing frame can drive the paper pushing mechanism to move. The C-shaped separator is detachably arranged on the tool rest. The paper pushing platform and the operation platform are both in contact with the C-shaped separator. The C-shaped separator is used to align the papers.

[0006] The driving device on the machine base drives the paper pushing frame to slide on the paper pushing platform. The paper pushing mechanism includes driving cylinders, a bracket, and multiple-stage paper pushing components. There are multiple driving cylinders, and all of the multiple driving cylinders are fixedly installed on the paper pushing frame. The output end of the driving cylinder penetrates the paper pushing frame, and the output end of the driving cylinder faces the cutter frame. The bracket is fixedly connected to the side of the paper pushing frame away from the cutter frame, and the bracket is in contact with the paper pushing platform. There are multiple multiple-stage paper pushing components, and all of the multiple multiple-stage paper pushing components are fixedly connected to the output end of the driving cylinder. The multiple-stage paper pushing components are used to push papers of various sizes respectively. The multiple-stage paper pushing component includes multiple paper pushing plates, and each paper pushing plate is fixedly connected to the output end of one driving cylinder. A toothed plate is arranged on the side of the paper pushing plate close to the cutter frame.

[0007] The width of the paper pushing plates in each multiple-stage paper pushing component is the same as that of the paper pushing plates in other multiple-stage paper pushing components, and the length between the toothed plate and the driving cylinder is different. The multiple multiple-stage paper pushing components are arranged at equal intervals on the paper pushing frame. When the output ends of all driving cylinders extend by the same length, the distances between the toothed plates and the cutter frame in the multiple multiple-stage paper pushing components gradually become shorter in sequence.

[0008] Multiple card slots are arranged on the cutter frame, and the C-shaped separator is detachably arranged on the card slots. The gap between the C-shaped separator and the adjacent paper pushing plate is aligned. When the paper pushing frame slides towards the cutter frame, the C-shaped separator extends into the gap between the adjacent paper pushing plates.

[0009] The multi-station starting mechanism is fixedly arranged on the side of the operation platform. The multi-station starting mechanism is used to control the start of the cutting knife device. When all staff control the multi-station starting mechanism, the cutting knife device starts. The multi-station starting mechanism includes a docking track, a placement groove, connection sockets, and start switches. The docking track is opened on the side of the operation platform. There are two placement grooves, and the two placement grooves are respectively opened at both ends of the operation platform. There are multiple connection sockets, and the multiple connection sockets are opened at equal intervals in the docking track. There are multiple start switches, and the start switches are detachably arranged in the placement grooves and the connection sockets.

[0010] After multiple start switches are respectively connected to multiple connection sockets, the start switches and the connection sockets are electrically connected. After all the start switches electrically connected to the connection sockets are turned on, the cutting knife device starts to cut the paper.

[0011] The toothed plates on the paper pushing plates with different lengths in the two multi-stage paper pushing assemblies can be aligned under the pushing of the output ends of multiple driving cylinders.

[0012] A paper cutting method for multi-station synchronous cutting, according to the above-mentioned paper cutting equipment for multi-station synchronous cutting, includes the following steps: Step 1. Adjust the width: According to the size of the paper to be cut, set multiple driving cylinders to push the paper pushing plates respectively, and set the C-shaped partition plate between adjacent workers; Step 2. Personnel configuration: Each worker docks one of the start switches with the connection socket corresponding to the working position; Step 3. Paper pushing: The paper pushing frame slides towards the knife rest, the toothed plate on the paper pushing plate pushes the paper, and the C-shaped partition plate extends into the gap between adjacent paper pushing plates; Step 4. Perform cutting: Push multiple groups of papers to align the edges of the papers with the cutting knife device. After each worker starts the start switch, the cutting knife device cuts the papers; Step 5. Circular cutting: After cutting is completed, the worker rotates the paper so that the uncut side is aligned with the cutting knife device. The paper pushing frame drives the multi-stage paper pushing assembly to push the paper. The worker can push the paper onto the C-shaped partition plate to align the papers, and then perform cutting again.

[0013] The beneficial effects of the embodiments of the present disclosure are as follows: 1. In the present invention, by setting multiple paper pushing plates and driving cylinders, independent multiple groups of driving cylinders are connected to the paper pushing plates. According to the size of the paper, the corresponding number of driving cylinders push the paper pushing plates to limit the paper, and other paper pushing plates push other papers, thereby making full use of the cutting knife device; 2. In the present invention, by setting the start switch, after all workers have placed the papers, they press the start switch, and then the cutting knife device performs cutting, which can avoid cutting the papers when they are not properly placed; 3. In the present invention, by setting the paper pushing mechanism, the pushing width can be set according to the different sizes of the papers, thereby making full use of the cutting knife device and the paper pushing frame. By setting the multi-station start mechanism, when multiple workers perform multi-station operations, it can be confirmed that all multiple workers are ready before cutting, which can avoid damage and personal injury caused by simultaneous cutting.

[0022] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0023] Embodiment 1 As Figures 1 to 6 shown, it shows a paper cutting device for multi-station synchronous cutting in an embodiment of this disclosure, including a machine base 1, an operation platform 2, a paper pushing platform 3, and a tool rest 4. The operation platform 2, the paper pushing platform 3, and the tool rest 4 are all fixedly installed on the machine base 1. The operation platform 2 and the paper pushing platform 3 are respectively arranged on both sides of the tool rest 4. A cutting knife device 5 is arranged on the tool rest 4. It also includes a paper pushing frame 6, a paper pushing mechanism, a multi-station starting mechanism, and a C-shaped separator. The paper pushing frame 6 is slidably arranged on the paper pushing platform 3. The paper pushing mechanism is fixedly connected to the paper pushing frame 6. The paper pushing mechanism is used to respectively push and limit multiple papers of different sizes. The paper pushing frame 6 can drive the paper pushing mechanism to move. The C-shaped separator 7 is detachably arranged on the tool rest 4. The paper pushing platform 3 and the operation platform 2 are both in contact with the C-shaped separator 7. The C-shaped separator 7 is used to align the papers. The papers are positioned on the paper pushing platform 3 under the push of the paper pushing mechanism.

[0024] As Figures 1 to 6 shown, the driving device on the machine base 1 drives the paper pushing frame 6 to slide on the paper pushing platform 3. The paper pushing mechanism includes a driving cylinder 8, a bracket 9 and multiple-stage paper pushing components. There are multiple driving cylinders 8, and multiple driving cylinders 8 are all fixedly installed on the paper pushing frame 6. The output end of the driving cylinder 8 penetrates through the paper pushing frame 6, and the output end of the driving cylinder 8 faces the tool rest 4. The bracket 9 is fixedly connected to the side of the paper pushing frame 6 away from the tool rest 4. The bracket 9 is in contact with the paper pushing platform 3, and the paper pushing frame 6 is supported by the bracket 9 to prevent the multiple driving cylinders 8 from causing the paper pushing frame 6 to tilt. There are multiple multiple-stage paper pushing components, and multiple multiple-stage paper pushing components are all fixedly connected to the output end of the driving cylinder 8. The multiple-stage paper pushing components are used to push papers of various sizes respectively. The multiple-stage paper pushing components include multiple paper pushing plates 10. Each paper pushing plate 10 is fixedly connected to the output end of one driving cylinder 8. A toothed plate 11 is arranged on the side of the paper pushing plate 10 close to the tool rest 4. The whole paper pushing frame 6 drives three multiple-stage paper pushing components to move. When performing multi-sided cutting of papers, the driving cylinders 8 on the three multiple-stage paper pushing components push the paper pushing plates 10 of different sizes respectively.

[0025] As Figures 1 to 4 shown, compared with the paper pushing plates 10 in other multiple-stage paper pushing components, the paper pushing plates 10 in each multiple-stage paper pushing component have the same width, and the length between the toothed plate 11 and the driving cylinder 8 is different. The multiple multiple-stage paper pushing components are arranged on the paper pushing frame 6 at equal intervals. When the output ends of each driving cylinder 8 extend by the same length, the distances between the toothed plate 11 and the tool rest 4 in the multiple multiple-stage paper pushing components gradually become shorter in turn. In this embodiment, the multiple-stage paper pushing components are specifically three. The multiple-stage paper pushing components include three paper pushing plates 10, a total of nine paper pushing plates 10 and nine driving cylinders 8. The nine paper pushing plates 10 are arranged at equal intervals, and there are gaps between them. From left to right, the lengths of the paper pushing plates 10 in different multiple-stage paper pushing components gradually become shorter. When cutting papers of different sizes, the larger papers can be placed on the right side of the operation platform 2, and the smaller papers are placed on the left side of the operation platform 2, which is convenient for paper alignment and rotation adjustment.

[0026] As Figures 1 to 4 shown, multiple card slots 12 are arranged on the tool rest 4. The C-shaped separator 7 is detachably arranged on the card slots 12, and the gap between the C-shaped separator 7 and the adjacent paper pushing plate 10 is aligned. When the paper pushing frame 6 slides towards the tool rest 4, the C-shaped separator 7 extends into the gap between the adjacent paper pushing plates 10. After the C-shaped separator 7 is fixed on the card slots 12, the staff can align multiple papers by pushing the papers onto the C-shaped separator 7. At the same time, the papers can also be aligned through both sides of the tool rest 4. Therefore, when cutting N different papers at the same time, N - 2 C-shaped separators 7 can be set.

[0027] AsFigures 5 to 6 As shown, the multi-station starting mechanism is fixedly arranged on the side of the operation platform 2. The multi-station starting mechanism is used to control the start of the cutting knife device 5. When all the staff control the multi-station starting mechanism, the cutting knife device 5 starts. The multi-station starting mechanism includes a docking track 13, a placement groove 14, a connection socket 15 and a start switch 16. The docking track 13 is opened on the side of the operation platform 2. There are two placement grooves 14, and the two placement grooves 14 are respectively opened at both ends of the operation platform 2. There are multiple connection sockets 15, and the multiple connection sockets 15 are equidistantly opened in the docking track 13. There are multiple start switches 16, and the start switches 16 are detachably arranged in the placement groove 14 and the connection socket 15. When the multiple start switches 16 are respectively connected to the multiple connection sockets 15, the start switch 16 and the connection socket 15 are electrically connected. After all the start switches 16 electrically connected to the connection socket 15 are turned on, the cutting knife device 5 starts to cut the paper. By using one cutting knife device 5 to cut multiple papers, after each staff member docks one start switch 16 with the connection socket 15 near their working position and all align the positions of the papers, and then all press the start switch 16, it is considered that the placement of the papers is completed and then the cutting will be carried out, avoiding the situation that someone's paper is not placed properly or someone's hand is under the cutting knife device 5 and others do not notice and cause danger. Each person pressing the start switch 16 can be regarded as having completed the adjustment of the paper and being ready for cutting. The start switch 16 and the docking track 13 can refer to the structure of the track socket. When the start switch 16 is in the placement groove 14, it is not connected.

[0028] As Figures 1 to 4 As shown, the toothed plates 11 on the paper pushing plates 10 with different lengths in the two multi-stage paper pushing components can be kept aligned under the push of the output ends of multiple driving cylinders 8. In this embodiment, three multi-stage paper pushing components push the paper. When the size of the paper to be pushed is relatively large, five or six paper pushing plates 10 can be used to push the paper. Through the cooperation of the extended lengths of the output ends of multiple driving cylinders 8, the toothed plates 11 on the paper pushing plates 10 with different lengths can be kept flush. Through multiple independent driving cylinders 8, papers of various different sizes can be cut. One paper cutting machine can push and cut three smaller papers, or one large and one small paper, or one larger paper. Through the mutual cooperation of a total of nine paper pushing plates 10 in this embodiment, papers of various sizes can be cut simultaneously, and thus multi-station cutting can be carried out more flexibly.

[0029] In some examples, papers of multiple sizes can be cut simultaneously, making full use of the length of the cutting knife device 5. The corresponding number of paper push plates 10 are set to push according to the size of the paper. With multiple independent driving cylinders 8 and paper push plates 10 of different lengths, papers of various sizes can be accommodated, thus making full use of the cutting knife device 5. Moreover, through multiple start switches 16, incorrect cutting of the paper or injury to personnel can be avoided.

[0030] Embodiment 2 A paper cutting method for multi-station synchronous cutting, according to the above-mentioned paper cutting equipment for multi-station synchronous cutting, includes the following steps: Step 1. Adjust the width: According to the size of the paper to be cut, set multiple driving cylinders 8 to push the paper push plates 10 respectively, and set the C-shaped partition plate 7 between adjacent workers. Step 2. Personnel configuration: Each worker docks a start switch 16 with the connection socket 15 corresponding to the working position. Step 3. Paper pushing: The paper pushing frame 6 slides towards the knife rest 4, and the toothed plate 11 on the paper push plate 10 pushes the paper, and the C-shaped partition plate 7 extends into the gap between adjacent paper push plates 10. Step 4. Perform cutting: Push multiple groups of papers to align the edges of the papers with the cutting knife device 5. After each worker starts the start switch 16, the cutting knife device 5 cuts the paper. Step 5. Circular cutting: After cutting is completed, the worker rotates the paper so that the uncut side is aligned with the cutting knife device 5. The paper pushing frame 6 drives the multi-stage paper pushing assembly to push the paper. The worker can push the paper onto the C-shaped partition plate 7 to align the papers, and then perform cutting again.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
