Description

Technical Field

[0001] The present invention relates to the technical field of paper processing equipment, and more specifically to a paper jam processing structure of a creasing machine and a creasing machine. Background Art

[0002] In the paper post-processing industry, when post-press equipment such as laminators, creasing machines, and binders are working, the paper head often warps up when it enters the next processing device from the paper feed device, especially the laminated paper is more prone to warping. The upturned paper head makes it easy for the front end of the paper to hit the paper feed side of the next processing device. Continuing to transport the paper forward will cause the paper to pile up between the next processing device and the paper feed device, causing paper jams. Paper jams seriously affect the normal use of post-press equipment.

[0003] In the prior art, an anti-jam structure is provided in the creasing machine to prevent paper from piling up and jamming. The anti-jam structure is generally installed at the front end of the upper and lower cutting dies. When the paper is transported by the paper feeding device, it will first pass through the anti-jam structure to eliminate the problem of the paper head curling up, and then enter the upper and lower cutting dies for stamping and forming. However, the anti-jam structure can only eliminate the problem of the paper head curling up slightly. If the paper head curls up severely, the front end of the paper is likely to hit the anti-jam structure and cause a paper jam, causing the creasing machine to fail to work properly, and the jammed paper must be removed. Since the structure between the creasing unit and the output end of the paper feeding unit is often compact and the gap is extremely small, it is impossible for a person to reach in. To clear out all the jammed paper, the anti-jam structure must be removed. In the prior art, to remove the anti-jam structure, the cutting die, the knife beam and the entire knife seat must be removed, and it will also be affected by the installation position of the sensor in the creasing unit. When reinstalling, the high alignment accuracy of the upper and lower cutting dies must also be considered, and the operation is very cumbersome and inconvenient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a paper jam processing structure for a creasing machine, which can quickly remove the anti-paper jam structure when a paper jam occurs, and take out the jammed paper. When reinstalling, there is no need to consider the alignment accuracy of the upper and lower cutting dies, thereby improving the disassembly and assembly efficiency of the paper jam processing structure of the creasing machine.

[0005] The technical solution of the present invention is to provide a paper jam processing structure of a creasing machine, including a mounting seat, a guide rail member, a knife beam, an upper knife die seat and an upper guide member; the knife beam is installed above the mounting seat so as to be disassembled and assembled in the up and down directions; the upper knife die seat is connected to the bottom of the knife beam, and an upper knife die is installed in the upper knife die seat or below the upper knife die seat; both ends of the upper knife die seat are slidably installed on the guide rail member, and the upper knife die seat and the guide rail member are separable; an upper guide member is installed on the side of the upper knife die seat, and the front end of the upper guide member and the output end of the paper feeding unit are arranged to avoid each other, and the lower surface of the upper guide member is provided with an upper guide surface for guiding the paper.

[0006] Compared with the prior art, the paper jam handling structure of the creasing machine of the present invention has the following advantages: when a paper jam occurs, the knife beam is removed from above the mounting seat, and then the knife beam, the upper knife die seat and the upper guide member can be lifted upward as a whole, the anti-paper jam structure can be quickly removed, and the jammed paper can be taken out, and the operation is convenient; when reinstalling, just put the knife beam, the upper knife die seat and the upper guide member back in place as a whole, and install the knife beam above the mounting seat to complete the installation, without considering the alignment accuracy of the upper and lower knife dies, which greatly improves the disassembly and assembly efficiency of the paper jam handling structure of the creasing machine; the front end of the upper guide member and the output end of the paper feeding unit are arranged to avoid each other, ensuring that the upper guide member will not interfere with the output end of the paper feeding unit during the process of being lifted upward together with the upper knife die seat and the knife beam.

[0007] Preferably, the guide rail is provided with a disassembly channel, and the two ends of the upper die holder are respectively slidably fitted in the disassembly channel, and the upper die holder can be disassembled upward along the disassembly channel. With this structure, it is convenient to separate the upper die holder from the guide rail, so that the knife beam, the upper die holder and the upper guide can be disassembled upward along the disassembly channel as a whole, and paper jams can be quickly handled.

[0008] Preferably, the guide rail member on one side of the upper die holder is composed of two guide rail blocks, the two guide rail blocks are spaced opposite to each other, and the disassembly channel is located between the two guide rail blocks. With this structure, the guide rail member is composed of two guide rail blocks, which is convenient for processing and manufacturing, and reduces the difficulty and cost of processing and manufacturing.

[0009] Preferably, a mounting block is provided above each guide rail block, and the two mounting blocks above the two guide rail blocks on the same side are spaced apart from each other and together form a mounting seat, and the disassembly passage is also located between the two mounting blocks. With this structure, it is convenient to dismantle the knife beam, the upper knife die seat and the upper guide piece upward along the disassembly passage as a whole; the mounting seat is composed of two mounting blocks, which is convenient for processing and manufacturing, and reduces the difficulty and cost of processing and manufacturing.

[0010] Preferably, the mounting block is provided with at least two positioning pin holes and at least one fastener locking hole. With this structure, the mounting block can be accurately positioned, so that the installation position of the knife beam is accurate, and thus the installation position of the upper knife die seat is accurate, which is conducive to accurate alignment of the upper and lower knife dies.

[0011] Preferably, friction plates are provided at both ends of the upper die seat, and both ends of the upper die seat are slidably matched with the guide rail through the friction plates, and assembly holes are provided on the friction plates, and the assembly holes are avoided from the mounting seat. With this structure, only fine processing of the friction plates is required to achieve the sliding matching accuracy between the two ends of the upper die seat and the guide rail, reducing the overall processing and manufacturing difficulty of the upper die seat; the assembly holes are avoided from the mounting seat, and in the process of the upper die seat and the knife beam being raised upward together, the assembly parts on the upper die seat, such as screws, can avoid interference with the mounting seat.

[0012] Preferably, a bending portion is provided on the friction plate, and the two ends of the bending portion are respectively matched with the side surface and the bottom surface of the upper die seat, and a friction plate is provided on each of the two side surfaces of the end of the upper die seat. The friction plate used in the prior art has two bends, which can be tightly attached to the two side surfaces and one bottom surface of the upper die seat at the same time. The tolerance between the two bends is large, so that the two side surfaces of the upper die seat and the friction plate are poorly matched. During the up and down movement of the upper die seat, the friction plate may swing, resulting in poor sliding fit accuracy between the friction plate and the guide rail. With this structure, it is possible to avoid the friction plate swinging when the upper die seat moves up and down, which may cause the sliding fit accuracy between the friction plate and the guide rail to deteriorate, and it is also possible to reduce the processing difficulty of the friction plate.

[0013] Preferably, a sensor seat for installing a sensor is provided on the mounting seat or the guide rail, and the upper guide member avoids the sensor seat. With this structure, when the upper guide member is lifted upward together with the upper die holder and the knife beam, interference between the upper guide member and the sensor seat can be avoided, which facilitates the removal of the upper guide member, the upper die holder and the knife beam upward together, and also facilitates the installation of the upper guide member, the upper die holder and the knife beam in place.

[0014] Preferably, a guide chamfer is provided at the lower part of the upper die holder at a position corresponding to the sensor holder, and the upper guide surface and the guide chamfer are used together to guide the paper. With this structure, when the width of the upper guide member is shortened due to avoiding the sensor holder, the upper guide surface and the guide chamfer are used together to guide the paper, which can prevent the head of the paper from warping up and causing paper jam.

[0015] Another technical problem to be solved by the present invention is to provide a creasing machine, which is equipped with a paper jam processing structure of the creasing machine. When a paper jam occurs, the anti-paper jam structure can be quickly removed to remove the jammed paper. When reinstalling, there is no need to consider the alignment accuracy of the upper and lower cutting dies, thereby improving the disassembly and assembly efficiency of the paper jam processing structure of the creasing machine.

[0016] The technical solution of the present invention is to provide a creasing machine, including a machine body, on which a paper feeding unit and a creasing unit are arranged, and also includes a paper jam handling structure of the creasing machine as described above, wherein the paper feeding unit is used to convey paper to the creasing unit, and the paper jam handling structure of the creasing machine can quickly remove the knife beam, the upper knife die seat and the upper guide when a paper jam occurs.

[0017] Compared with the prior art, the creasing machine of the present invention has the following advantages: when a paper jam occurs, the knife beam is removed from above the mounting seat, and then the knife beam, the upper knife die seat and the upper guide member can be lifted upward as a whole, the anti-paper jam structure can be quickly removed, and the jammed paper can be taken out, and the operation is convenient; when reinstalling, just put the knife beam, the upper knife die seat and the upper guide member back in place as a whole, and install the knife beam above the mounting seat to complete the installation, without considering the alignment accuracy of the upper and lower knife dies, greatly improving the disassembly and assembly efficiency of the paper jam processing structure of the creasing machine; the front end of the upper guide member and the output end of the paper feeding unit are arranged to avoid each other, ensuring that the upper guide member will not interfere with the output end of the paper feeding unit during the process of being lifted upward together with the upper knife die seat and the knife beam.

[0018] Preferably, the mounting seat is arranged on both sides of the machine body, and a position avoidance structure is arranged on the machine body at positions corresponding to the two ends of the blade beam, and the said position avoidance structure is used to avoid the two ends of the blade beam. With this structure, the mounting seat can be as close to the two sides of the machine body as possible, shortening the force arm, which is conducive to improving the load capacity of the mounting seat.
