Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of paper cutter technology, and more specifically, to a multi-station synchronous paper cutting device and method. Background Technology

[0002] A paper cutter is a machine used to handle the paper cutting needs in the later stages of printing. Stacks of paper are placed on the platform of the paper cutter. The paper pushing system on the paper cutter limits the position of the paper. Then, the paper pressing device holds the paper down, and the cutting device cuts the paper. Afterwards, the paper is rotated on the platform by the operator, so that the other uncut side faces the cutting device. The paper pushing system adjusts the pushing distance according to the different widths of the paper, thus completing the cutting of multiple edges of the paper in one go.

[0003] Existing paper cutters are often equipped with a long cutting blade and a paper pushing system of the same width. However, most of the paper being cut is less than half the length of the cutting blade. When an operator rotates and aligns the paper, a large portion of the cutting blade will not cut the paper, resulting in low utilization of the equipment. Summary of the Invention

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

[0005] According to one aspect, at least one embodiment of this disclosure provides a multi-station synchronous paper cutting device, including a base, an operating platform, a paper pushing platform, and a knife holder. The operating platform, the paper pushing platform, and the knife holder are all fixedly mounted on the base. The operating platform and the paper pushing platform are respectively disposed on both sides of the knife holder. The knife holder is provided with a cutting blade device. The device also includes a paper pushing frame, a paper pushing mechanism, and a C-shaped partition plate. The paper pushing frame is slidably disposed on the paper pushing platform. The paper pushing mechanism is fixedly connected to the paper pushing frame. The paper pushing mechanism is used to push and limit multiple sheets of different sizes of paper. The paper pushing frame can drive the paper pushing mechanism to move. The C-shaped partition plate is detachably disposed on the knife holder. The paper pushing platform and the operating platform are both in contact with the C-shaped partition plate. The C-shaped partition plate is used to align the sheets.

[0006] The drive device on the base drives the paper pusher to slide on the paper pusher platform. The paper pusher mechanism includes a drive cylinder, a bracket, and a multi-stage paper pusher assembly. Multiple drive cylinders are provided, and all of them are fixedly installed on the paper pusher. The output end of the drive cylinder passes through the paper pusher and faces the knife holder. The bracket is fixedly connected to the side of the paper pusher away from the knife holder and contacts the paper pusher platform. Multiple multi-stage paper pusher assemblies are provided, and all of them are fixedly connected to the output end of the drive cylinder. The multi-stage paper pusher assembly is used to push paper of various sizes. The multi-stage paper pusher assembly includes multiple paper push plates, and each paper push plate is fixedly connected to the output end of one of the drive cylinders. A toothed plate is provided on the side of the paper push plate near the knife holder.

[0007] The paper pusher plate in each of the multi-stage paper pusher assemblies has the same width as the paper pusher plate in the other multi-stage paper pusher assemblies, but the length between the toothed plate and the drive cylinder is different. The multiple multi-stage paper pusher assemblies are arranged at equal intervals on the paper pusher frame. When the output end of each drive cylinder extends by the same length, the distance between the toothed plate and the knife holder in the multiple multi-stage paper pusher assemblies becomes shorter in sequence.

[0008] The knife holder is provided with multiple slots, and the C-shaped divider is detachably mounted on the slots. The C-shaped divider is aligned with the gap between the adjacent paper pusher plate. When the paper pusher slides towards the knife holder, the C-shaped divider plate extends into the gap between the adjacent paper pusher plates.

[0009] A multi-station starting mechanism is fixedly installed on the side of the operating platform. The multi-station starting mechanism is used to control the start of the cutting knife device. When all operators control the multi-station starting mechanism, the cutting knife device starts. The multi-station starting mechanism includes a docking rail, a placement slot, a connection port, and a start switch. The docking rail is located on the side of the operating platform. There are two placement slots, which are respectively located at both ends of the operating platform. There are multiple connection ports, which are equally spaced in the docking rail. There are multiple start switches, which are detachably installed in the placement slot and the connection port.

[0010] When the multiple start switches are connected to the multiple connection sockets respectively, 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 device starts to cut the paper.

[0011] The toothed plates on the paper pushers of different lengths in the two multi-stage paper pusher assemblies can be kept aligned by the push of the output ends of multiple drive cylinders.

[0012] A multi-station synchronous paper cutting method, based on the aforementioned multi-station synchronous paper cutting equipment, includes the following steps: Step 1: Adjust the width: According to the size of the paper to be cut, set up multiple drive cylinders to push the paper pusher plate respectively, and place the C-shaped divider plate between adjacent workers; Step 2, Personnel Configuration: Each worker connects one of the aforementioned start switches to the corresponding connection port at their work position; Step 3, Paper Pushing: The paper pusher slides toward the cutter holder, the toothed plate on the paper pusher pushes the paper, and the C-shaped divider extends into the gap between adjacent paper pushers; Step 4: Cutting: Push multiple sets of paper until the edges of the paper are aligned with the cutting device. After each worker activates the start switch, the cutting device cuts the paper. Step 5, Cyclic Cutting: After cutting, the worker rotates the paper so that the uncut side is aligned with the cutting blade device. The paper pusher drives the multi-stage paper pusher assembly to push the paper. The worker can push the paper onto the C-shaped divider plate to align the papers, and then cut it again.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this invention, multiple paper push plates and driving cylinders are set up. The paper push plates are connected by multiple independent sets of driving cylinders. According to the size of the paper, a corresponding number of driving cylinders and paper push plates are set to push the paper to a limit position. Other paper push plates push other papers, thereby making full use of the cutting knife device. 2. In this invention, by setting a start switch, all staff members press the start switch after placing the paper, and the cutting device then cuts the paper, which can avoid cutting the paper before it is properly placed. 3. In this invention, by setting a paper pushing mechanism, the pushing width can be set according to the different sizes of the paper, thereby making full use of the cutting knife device and the paper pushing frame. By setting a multi-station starting mechanism, when multiple workers are performing multi-station operations, it can be confirmed that multiple workers are ready before cutting, which can avoid damage and injury caused by simultaneous cutting.

[0023] Example 1 like Figures 1-6 The diagram illustrates a multi-station synchronous paper cutting device according to an embodiment of this disclosure. It includes a base 1, an operating platform 2, a paper pushing platform 3, and a blade holder 4. The operating platform 2, paper pushing platform 3, and blade holder 4 are all fixedly mounted on the base 1. The operating platform 2 and paper pushing platform 3 are respectively positioned on opposite sides of the blade holder 4. A cutting blade device 5 is mounted on the blade holder 4. The device also includes a paper pushing frame 6, a paper pushing mechanism, a multi-station starting mechanism, and a C-shaped partition plate. The paper pushing frame 6 is slidably mounted on the paper pushing platform 3. The paper pushing mechanism is fixedly connected to the paper pushing frame 6 and is used to push and limit multiple sheets of different sizes. The paper pushing frame 6 can drive the paper pushing mechanism to move. The C-shaped partition plate 7 is detachably mounted on the blade holder 4. Both the paper pushing platform 3 and the operating platform 2 are in contact with the C-shaped partition plate 7. The C-shaped partition plate 7 is used to align the sheets. The sheets are positioned on the paper pushing platform 3 by the pushing mechanism.

[0024] like Figures 1-6 As shown, the drive unit on the base 1 drives the paper pusher 6 to slide on the paper pusher platform 3. The paper pusher mechanism includes drive cylinders 8, brackets 9, and a multi-stage paper pusher assembly. Multiple drive cylinders 8 are provided, all fixedly mounted on the paper pusher 6. The output ends of the drive cylinders 8 pass through the paper pusher 6 and face the knife holder 4. The bracket 9 is fixedly connected to the side of the paper pusher 6 away from the knife holder 4. The bracket 9 contacts the paper pusher platform 3, supporting the paper pusher 6 and preventing it from tilting due to the multiple drive cylinders 8. The multi-stage paper pusher assembly is... The device has multiple multi-stage paper pushing assemblies, each fixedly connected to the output end of a drive cylinder 8. The multi-stage paper pushing assemblies are used to push various sizes of paper. Each multi-stage paper pushing assembly includes multiple paper push plates 10, each of which is fixedly connected to the output end of a drive cylinder 8. A toothed plate 11 is provided on the side of the paper push plate 10 near the cutter holder 4. The paper pushing frame 6 drives the three multi-stage paper pushing assemblies to move as a whole. When cutting the paper into multiple shapes, the drive cylinders 8 on the three multi-stage paper pushing assemblies push the paper push plates 10 of different sizes respectively.

[0025] like Figures 1-4 As shown, the paper pusher plate 10 in each multi-stage paper pusher assembly has the same width as the paper pusher plate 10 in other multi-stage paper pusher assemblies, but the length between the toothed plate 11 and the drive cylinder 8 is different. Multiple multi-stage paper pusher assemblies are arranged at equal intervals on the paper pusher frame 6. When the extension length of the output end of each drive cylinder 8 is the same, the distance between the toothed plate 11 and the cutter holder 4 in multiple multi-stage paper pusher assemblies becomes shorter in sequence. In this embodiment, there are three multi-stage paper pusher assemblies, each including three paper pusher plates 10, for a total of nine paper pusher plates 10 and nine drive cylinders 8. The nine paper pusher plates 10 are arranged at equal intervals, with gaps between them. From left to right, the length of the paper pusher plate 10 in different multi-stage paper pusher assemblies becomes shorter in sequence. When cutting paper of different sizes, larger paper can be placed on the right side of the operating platform 2, and smaller paper can be placed on the left side of the operating platform 2, which facilitates paper alignment and rotation adjustment.

[0026] like Figures 1-4 As shown, the cutter holder 4 is provided with multiple slots 12. The C-shaped divider 7 is detachably mounted on the slot 12. The gap between the C-shaped divider 7 and the adjacent paper pusher 10 is aligned. When the paper pusher 6 slides towards the cutter holder 4, the C-shaped divider 7 extends into the gap between the adjacent paper pusher 10. After the C-shaped divider 7 is fixed on the slot 12, the operator can push the paper onto the C-shaped divider 7 to align multiple sheets of paper. At the same time, the paper can also be aligned through both sides of the cutter holder 4. Therefore, when cutting N different sheets of paper at the same time, N-2 C-shaped dividers 7 can be set.

[0027] like Figures 5-6 As shown, a multi-station starting mechanism is fixedly installed on the side of the operating platform 2. This mechanism controls the starting of the cutting blade device 5. When all operators control the multi-station starting mechanism, the cutting blade device 5 starts. The multi-station starting mechanism includes a docking rail 13, a placement slot 14, a connecting socket 15, and a start switch 16. The docking rail 13 is located on the side of the operating platform 2. There are two placement slots 14, located at opposite ends of the operating platform 2. Multiple connecting sockets 15 are evenly spaced within the docking rail 13. Multiple start switches 16 are detachably installed in the placement slot 14 and connecting sockets 15. When multiple start switches 16 are connected to multiple connecting sockets 15, the start switches 16 and connecting sockets 15 activate. Electrical connection: After all the start switches 16, which are electrically connected to the connection socket 15, are turned on, the cutting device 5 starts to cut the paper. Multiple sheets of paper are cut by one cutting device 5. Each worker connects a start switch 16 to the connection socket 15 near their work position. After everyone aligns the paper, they press the start switch 16. This is considered as the paper placement being completed before cutting. This is to avoid danger caused by someone not placing the paper properly or a worker's hand under the cutting device 5 without others noticing. Each person pressing the start switch 16 is considered as having completed the paper adjustment and is ready to cut. The start switch 16 and the docking rail 13 can be referenced from the structure of the rail socket. When the start switch 16 is in the placement slot 14, it is not connected.

[0028] like Figures 1-4 As shown, the toothed plates 11 on the paper pushers 10 of different lengths in the two multi-stage paper pusher assemblies can be kept aligned by the push of the output ends of multiple drive cylinders 8. In this embodiment, the three multi-stage paper pusher assemblies push the paper. When the size of the paper being pushed is large, five or six paper pushers 10 can be used to push the paper. By coordinating the extension lengths of the output ends of multiple drive cylinders 8, the toothed plates 11 of paper pushers 10 of different lengths can be kept aligned. Through multiple independent drive cylinders 8, various sizes of paper can be cut. One paper cutter can push and cut three smaller pieces of paper, or two pieces of paper of different sizes, or one larger piece of paper. Through the mutual cooperation of the nine paper pushers 10 in this embodiment, various sizes of paper can be cut simultaneously, thus enabling more flexible multi-station cutting.

[0029] In some examples, multiple sizes of paper can be cut simultaneously, and the length of the cutting blade device 5 can be fully utilized. The number of paper pushers 10 is set according to the size of the paper and pushed. Through multiple independent drive cylinders 8 and paper pushers 10 of different lengths, various sizes of paper can be accommodated, thereby making full use of the cutting blade device 5. Furthermore, through multiple start switches 16, incorrect paper cutting or personal injury can be avoided.

[0030] Example 2 A multi-station synchronous paper cutting method, based on the aforementioned multi-station synchronous paper cutting equipment, includes the following steps: Step 1: Adjust the width: According to the size of the paper to be cut, set multiple drive cylinders 8 to push the paper pusher plate 10 respectively, and place the C-shaped divider plate 7 between adjacent workers. Step 2, Personnel Configuration: Each worker connects a start switch 16 to the corresponding connection port 15 at their work position; Step 3, Paper Pushing: The paper pusher 6 slides towards the knife holder 4, the toothed plate 11 on the paper pusher 10 pushes the paper, and the C-shaped divider 7 extends into the gap between adjacent paper pushers 10. Step 4: Cutting: Push multiple sets of paper until the edge of the paper is aligned with the cutting device 5. After each worker starts the start switch 16, the cutting device 5 cuts the paper. Step 5, Cyclic Cutting: After cutting, the worker rotates the paper so that the uncut side is aligned with the cutting blade device 5. The paper pusher 6 drives the multi-stage paper pusher assembly to push the paper. The worker can push the paper onto the C-shaped divider 7 to align the papers, and then cut it again.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
