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 knife beam, an upper knife holder 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 holder is connected to the bottom of the knife beam, and the two ends of the upper knife holder are slidably mounted on the mounting seat, and the upper knife holder is separable from the mounting seat; a knife die assembly is arranged below the upper knife holder, and the lower end surface of the upper knife holder serves as the upper support of the knife die assembly, and when the upper knife holder is removed upward, the upper knife holder and the knife die assembly can be separated up and down; the upper guide member is installed on the side of the upper knife holder or below the knife beam, 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 holder 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 holder 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 holder and the knife beam.

[0007] Preferably, the mounting seat is a guide rail member, the two ends of the upper knife holder are respectively guided and matched on the guide rail member, and the knife beam can be installed above the guide rail member in a disassembled manner in the up and down direction. With this structure, it is convenient to separate the upper knife holder from the mounting seat, so that the knife beam, the upper knife holder and the upper guide member can be lifted upward as a whole, so as to quickly deal with paper jams.

[0008] Preferably, the guide rail member is provided with an upper slide groove that can guide the upper knife holder, and upper sliding convex strips that slide with the upper slide groove are provided at both ends of the upper knife holder, and the upper knife holder can slide upward until the upper sliding convex strips at both ends are separated from the corresponding upper slide grooves to separate the upper knife holder from the guide rail member. With this structure, it is convenient to separate the upper knife holder from the mounting seat, so that the knife beam, the upper knife holder and the upper guide member can be lifted upward as a whole, and paper jams can be quickly handled.

[0009] Preferably, the knife die assembly is a one-piece knife die assembly in which an upper knife die and a lower knife die are connected up and down into one body, and a plane support or a concave-convex support is provided between the lower end surface of the upper knife holder and the upper knife die. With this structure, the one-piece knife die assembly does not affect the alignment accuracy of the upper and lower knife dies when disassembling and assembling the jam handling structure of the creasing machine, and after disassembling and assembling the jam handling structure of the creasing machine, the upper knife die and the lower knife die of the one-piece knife die assembly can be separated, and the paper can be pulled out from between the upper knife die and the lower knife die; a plane support or a concave-convex support is provided between the lower end surface of the upper knife holder and the upper knife die, so that when the upper knife holder is removed upward, the upper knife holder and the knife die assembly can be separated up and down; the concave-convex fit between the lower end surface of the upper knife holder and the upper knife die enables the upper knife holder to have a limiting effect on the knife die assembly when the upper knife holder is installed.

[0010] Preferably, the upper guide is provided with a plurality of longitudinal holes, and the upper guide is assembled on the side of the upper knife holder through the longitudinal holes. With this structure, the height of the upper guide relative to the upper knife holder can be adjusted by adjusting the position of the screw in the longitudinal hole, and the height of the upper guide surface for guiding the paper can be adjusted to reduce the probability of paper jam.

[0011] Preferably, the upper guide can float up and down. With this structure, the upper guide can adapt to the thickness of the paper and reduce the probability of paper jam. As long as the screw connecting the upper guide and the upper knife holder is not locked in the longitudinal hole, the upper guide can float up and down.

[0012] Preferably, a sensor seat for mounting the sensor is provided on the mounting seat, and the upper guide member avoids the sensor seat. With this structure, the guide member avoids the sensor seat, which can prevent the upper guide member from interfering with the sensor seat during the process of being raised upward with the upper tool holder and the tool beam.

[0013] Preferably, an auxiliary upper guide surface is provided at a position on the mounting seat corresponding to the sensor seat, and the upper guide surface and the auxiliary upper guide surface 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 seat, the auxiliary upper guide surface guides the end of the paper head corresponding to the sensor seat, which can prevent the paper head from warping up and causing paper jams.

[0014] Preferably, a secondary guide is provided at a position corresponding to the sensor seat on the upper knife holder, and a secondary guide surface is provided on the lower surface of the secondary guide, and the upper guide surface and the secondary guide surface are used together to guide the paper. With this structure, when the width of the upper guide is shortened due to avoiding the sensor seat, the secondary guide surface guides the end of the paper head corresponding to the sensor seat, which can prevent the paper head from warping up and causing paper jams.

[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 a paper jam handling structure of the creasing machine as described above is arranged between the paper feeding unit and the creasing unit.

The upper tool holder 2 is connected below the tool beam 1, and a buffer member 12 is further provided between the upper tool holder 2 and the tool beam 1. Upper sliding convex strips 2-1 are provided at both ends of the upper tool holder 2. The first mounting seat 9 and the second mounting seat 10 are both guide rail members and are both provided with upper slide grooves. The upper sliding convex strips 2-1 at both ends of the upper tool holder 2 are respectively limited in the corresponding upper slide grooves and can slide up and down along the upper slide grooves. The upper tool holder 2 can slide upward to cause the upper sliding convex strips 2-1 at both ends to be separated from the corresponding upper slide grooves. The upper guide 6 is provided with a plurality of longitudinal holes 6-1, and the upper guide 6 is assembled on the side of the upper knife holder 2 through the longitudinal holes 6-1. The lower surface of the upper guide 6 is provided with an upper guide surface 6-2 for guiding the paper. The height of the upper guide 6 relative to the upper knife holder 2 can be adjusted by adjusting the position of the screw in the longitudinal hole 6-1, that is, the height of the upper guide surface 6-2 for guiding the paper can be adjusted. The screws for connecting the upper guide and the upper knife holder can also be unlocked, so that the upper guide can float up and down adaptively with the thickness of the paper.

[0032] A lower tool holder 3 is also provided below the upper tool holder 2. Lower sliding ridges 3-1 are provided at both ends of the lower tool holder 3. A sliding groove is provided on the first mounting seat 9. A sliding groove 10-5 is also provided on the second mounting seat 10. The lower sliding ridges 3-1 at both ends of the lower tool holder 3 are respectively limited in the corresponding sliding grooves and can slide up and down along the sliding grooves.

[0033] A cutting die assembly 4 is arranged between the upper tool holder 2 and the lower tool holder 3. The cutting die assembly is mounted on the first mounting seat 9 and the second mounting seat 10. The lower end surface of the upper tool holder 2 serves as the upper support of the cutting die assembly, and the upper end surface of the lower tool holder 3 serves as the lower support of the cutting die assembly. A planar support or a concave-convex support can be provided between the upper tool holder 2 and the cutting die assembly. The concave-convex support can be a convex strip provided on the upper tool holder 2, and a groove matched with the convex strip is provided on the cutting die assembly.

[0034] The cutting die assembly includes an upper cutting die 4-1 and a lower cutting die 4-2. The upper cutting die 4-1 is located above the lower cutting die 4-2. A connecting rod is arranged between the upper cutting die 4-1 and the lower cutting die 4-2. The connecting rod connects the upper cutting die 4-1 and the lower cutting die 4-2 into a whole. A spring is arranged on the connecting rod. The two ends of the spring respectively contact with the two opposite surfaces of the upper cutting die 4-1 and the lower cutting die 4-2.

[0035] A first mounting hole 9-3 is provided between the upper slide groove and the lower slide groove on the first mounting seat 9, and a second mounting hole 10-3 is provided between the upper slide groove 10-2 and the lower slide groove 10-5 on the second mounting seat 10. The two ends of the upper cutting die 4-1 and the lower cutting die 4-2 are respectively plugged into the first mounting hole 9-3 and the second mounting hole 10-3, and the two ends of the upper cutting die 4-1 and the lower cutting die 4-2 can move up and down along the hole walls of the first mounting hole 9-3 and the second mounting hole 10-3. A pull rod 4-5 is provided on the lower cutting die 4-2, and the push-pull pull rod 4-5 can install the cutting die assembly 4 into the first mounting hole 9-3 and the second mounting hole 10-3 or extract it from the first mounting hole 9-3 and the second mounting hole 10-3. Cutting die guide plates 5 are also provided on both sides of the lower tool holder 3, and the cutting die guide plates 5 can guide the cutting die assembly 4 during the installation of the cutting die assembly 4.

[0036] The lower knife holder 3 supports the knife die assembly 4 and can drive the lower knife die 4-2 to move in the direction of the upper knife die 4-1. During this process, the spring on the connecting rod is compressed; when the lower knife holder 3 moves downward, the spring rebounds and causes the lower knife die 4-2 to move away from the upper knife die 4-1. The upper knife holder 2 supports the upper knife die 4-1. When the lower knife die 4-2 squeezes the upper knife die 4-1 to move the upper knife die 4-1 upward, the upper knife die 4-1 contacts and drives the upper knife holder 2 to move upward; when the lower knife die 4-2 moves in the direction away from the upper knife die 4-1, the upper knife die 4-1 moves downward under the action of gravity until it returns to its original position, and the upper knife holder 2 also moves downward under the action of gravity until it returns to its original position. At this time, the upper knife die 4-1 does not contact the upper knife holder 2.

[0037] In this embodiment, the paper feeding unit adopts a paper feeding roller group 8, the upper guide member 6 is opposite to the paper feeding roller group 8, and the front end of the upper guide member is arranged to avoid the paper feeding roller group 8, so that the upper guide member 6 will not interfere with the paper feeding roller group 8 when it is lifted upward together with the upper knife holder and the knife beam. The upper guide surface 6-2 includes an upper guide plane 6-21 and an upper guide inclined surface 6-22 inclined toward the upper guide plane, the upper guide inclined surface 6-22 is opposite to the paper feeding roller group 8, and the upper guide plane (6-21) is opposite to the paper feeding end of the knife die assembly.

[0038] The lower guide member 7 is arranged below the upper guide member 6, and the left and right ends of the lower guide member 7 are respectively mounted on the first mounting seat 9 and the second mounting seat 10 by screws, and the lower guide member 7 is also opposite to the paper feed roller group 8. The upper surface of the lower guide member 7 is provided with a lower guide surface 7-2, and the lower guide surface 7-2 is opposite to the upper guide surface 6-2. The lower guide surface 7-2 includes a lower guide plane 7-21 and a lower guide inclined surface 7-22 inclined toward the lower guide plane. The lower guide inclined surface 7-22 is opposite to the paper feed roller group 8, and the lower guide plane 7-21 is opposite to the paper feed end of the die cutter assembly.

[0039] The upper guide plane 6-21 is opposite to the lower guide plane 7-21, and the upper guide slope 6-22 and the lower guide slope 7-22 form an eight-shaped guide structure relative to the paper feed roller group 8. The eight-shaped guide structure has a large end on the side opposite to the paper feed roller group 8, which is beneficial for guiding the paper to between the upper guide plane 6-21 and the lower guide plane 7-21.

[0040] An upper cutting die guide plane and an upper cutting die guide inclined plane inclined toward the upper cutting die guide plane are arranged on the lower end surface of the upper cutting die 4-1; a lower cutting die guide plane and a lower cutting die guide inclined plane inclined toward the downward cutting die guide plane are arranged on the upper end surface of the lower cutting die 4-2; the upper cutting die guide inclined plane and the lower cutting die guide inclined plane form an eight-shaped guide structure, and the large end of the eight-shaped guide structure is opposite to the upper guide plane 6-21 and the lower guide plane 7-21, which is conducive to guiding the paper to between the upper cutting die guide plane 4-1 and the lower cutting die guide plane for creasing processing.

[0041] If a paper jam occurs, it is necessary to disassemble the paper jam handling structure of the creasing machine of the present invention and remove the jammed paper. Simply remove the knife beam 1 from the first mounting seat 9 and the second mounting seat 10, and the knife beam 1, the upper knife holder 2 and the upper guide member 6 can be lifted upward as a whole, which is easy to operate; when reinstalling, just put the knife beam 1, the upper knife holder 2 and the upper guide member 6 back in place as a whole, install the knife beam 1 above the mounting seat 9, and then insert the knife die assembly into 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. Since the left and right ends of the lower guide member 7 are correspondingly installed on the two mounting seats 9, disassembling the lower guide member 7 will not affect the knife die assembly and the knife seat.

[0042] like Figures 3 to 5 As shown in , a sensor seat 11 for installing a sensor is provided at a position on the second mounting seat 10 opposite to the upper guide member 6. The width of the upper guide member 6 is smaller than the width of the paper feed roller group 8 and the upper guide member 6 avoids the sensor seat 11. The upper guide member 6 will not interfere with the sensor seat 11 when it is lifted upward together with the upper knife holder 2 and the knife beam 1. An auxiliary upper guide surface 10-1 is provided at a position on the second mounting seat 10 corresponding to the sensor seat 11. The auxiliary upper guide surface 10-1 is substantially aligned with the orientation of the upper guide surface 6-2. The auxiliary upper guide surface 10-1 and the upper guide surface 6-2 are used together to guide the paper. When the width of the upper guide member 6 is shortened due to avoiding the sensor seat 11, the head of the paper is prevented from warping up and jamming due to the lack of guidance of the upper guide surface 6-2. An auxiliary guide piece 10-4 is provided on the auxiliary upper guide surface 10-1, and the auxiliary guide piece 10-4 is close to the auxiliary upper guide surface 10-1. The auxiliary guide piece 10-4 and the upper guide surface 6-2 are used together to guide the paper, which can reduce the processing accuracy of the auxiliary upper guide surface 10-1 and also reduce the manufacturing difficulty of the second mounting seat 10.

[0043] Embodiment 2:

[0044] like Figures 6 to 8 As shown in the figure, the paper jam handling structure of the creasing machine in this embodiment is different from that in embodiment 1 in that the upper part of the upper guide member 6 is close to the lower bottom surface of the knife beam 1 and is connected to the knife beam 1 by screws, and a secondary guide member 13 is arranged at a position corresponding to the sensor seat 11 on the upper knife holder 2, and a secondary guide surface 13-1 is arranged on the lower surface of the secondary guide member 13, and the upper guide surface 6-2 and the secondary guide surface 13-1 are used together to guide the paper to prevent the head of the paper from curling up.

[0045] Embodiment 3:

[0046] The present invention also discloses a creasing machine, including a machine body, on which a paper feeding unit, a creasing unit and a paper discharging unit are arranged, and an anti-paper jam structure is arranged between the paper feeding unit and the creasing unit. The anti-paper jam structure adopts the paper jam processing structure of the creasing machine in Example 1 or Example 2, the paper feeding unit and the paper discharging unit both adopt a paper feeding roller group, and the creasing unit adopts a knife die assembly, including the upper knife die 4-1 and the lower knife die 4-2 in the above-mentioned embodiment.

[0047] When the creasing machine of the present invention is working normally, after the paper feed roller group of the paper feeding unit outputs the paper, the paper must first pass through the anti-paper jam structure. Since the upper guide slope 6-22 and the lower guide slope 7-22 form an eight-shaped guide structure relative to the output end of the paper feeding unit, the paper enters between the lower guide surface 7-2 and the upper guide surface 6-2 from the large end of the eight-shaped guide structure. The eight-shaped guide structure can guide the paper with the head tilted upward to avoid the paper hitting the anti-paper jam structure and causing paper jam, thereby solving the problem of paper jam caused by the upward tilt of the paper head; after the paper is output from between the lower guide surface 7-2 and the upper guide surface 6-2, it will enter between the upper knife die 4-1 and the lower knife die 4-2 along the upper knife die guide slope and the lower knife die guide slope, that is, enter the creasing unit, and the upper knife die and the lower knife die jointly perform a creasing operation on the paper. The upper knife die guide slope can further solve the problem of paper jam caused by the upward tilt of the paper head, and avoid the paper hitting the side wall of the upper knife die and causing paper jam.

[0048] If a paper jam occurs, it is necessary to dismantle the anti-paper jam structure in the creasing machine of the present invention, and the method for dismantling the anti-paper jam structure described in Example 1 or Example 2 is adopted.

[0049] The above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
