Description

Technical Field

[0001] This utility model relates to the field of printing machinery, specifically to a rotary printing machine for continuous paper feeding and uninterrupted printing. Background Technology

[0002] A rotary printing press is a high-speed printing device that uses continuous roll paper. Its core feature is that the printing plate rotates around a cylinder, and the image information is transferred to the paper through the pressure of the cylinders. It is widely used in large-scale printing tasks, such as newspapers, magazines, books, and packaging materials. Because it is suitable for large-scale printing tasks, the roll paper often runs out during the printing process. At this time, it is necessary to replace the roll paper and splice the paper together to ensure that the printed image is continuous and complete.

[0003] Traditional printers require manual replacement of two paper rolls after slowing down and depressurizing. This method consumes a lot of manpower, especially during large-scale printing, where someone needs to be on duty next to the printer to ensure that the paper rolls are replenished immediately after each use, otherwise the production and printing schedule will be greatly delayed.

[0004] Therefore, there is a need for a rotary printing press that can automatically and stably complete the roll paper changing process, reducing the need for human resources. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a rotary printing machine that can automatically and stably complete the roll paper changing process and reduce the occupation of human resources.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A rotary printing press for continuous paper feeding and uninterrupted printing includes a printing mechanism and a continuous paper feeding mechanism; the continuous paper feeding mechanism includes a continuous paper feeding channel, a current paper feeding area, a preparatory paper feeding area, a storage paper feeding area, and a paper feeding management component.

[0008] The continuous paper feeding channel leads to the printing mechanism at its end and is able to transport printing paper to the printing mechanism;

[0009] The existing paper supply area is provided with a paper supply frame, and a paper supply slot is movably provided on the paper supply frame, and a first paper tube is provided in the paper supply slot;

[0010] Specifically, the first paper tube includes a first core and a first paper material surrounding the first core; the front end of the first paper material is guided to the printing mechanism by the continuous paper feeding channel;

[0011] The pre-feeding area is equipped with a pre-feeding chute, and a pre-feeding slot is provided on the pre-feeding chute. A second paper tube is provided in the pre-feeding slot.

[0012] Specifically, the second paper tube includes a second core and a second paper material surrounding the second core; the front end of the second paper material extends to the end of the continuous paper feeding channel to replace the first paper material;

[0013] The storage and paper supply area stores a third paper tube and is also equipped with a barrier to prevent the third paper tube from entering the pre-supply area; the third paper tube includes a third core and a third paper material surrounding the third core;

[0014] Specifically, the first, second, and third paper tubes have the same structure; the distinction is made here because they are located in different structural and production processes.

[0015] The paper supply management component includes a first replacement component for removing a first core without first paper material, a second replacement component for transferring a second paper tube that has replaced the first paper material to the current paper supply area, and a third replacement component for guiding a third paper tube to the pre-supply area.

[0016] By adopting the above technical solution, during printing operations, when the first paper roll in the current paper supply area runs out of paper, the second paper roll extending from the second paper roll in the preparatory paper supply area takes over and continues printing. Then, the first replacement component removes the first paper roll core from the paper supply slot in the current paper supply area, and the second replacement component transfers the second paper roll located in the preparatory paper supply area to the paper supply slot in the current paper supply area, thus replacing the used first paper roll with the second paper roll. The third replacement component guides the third paper roll stored in the storage paper supply area to the preparatory slot in the preparatory paper supply area, thus replacing the original second paper roll with the third paper roll. Since the actual structures of the first, second, and third paper rolls are the same, the printer can print continuously until the first, second, and all third paper rolls on the continuous paper feeding mechanism are used up. This process does not require manual replenishment of paper rolls, reducing the occupation of human resources and improving production efficiency.

[0017] As an improvement, a pressure roller is provided above the continuous paper feeding channel near the printing mechanism; a gluing assembly is provided below the current paper feeding area in the continuous paper feeding channel. The gluing assembly includes a glue strip placement platform located below the paper feeding slot, a glue strip replenishment device located on the side of the glue strip placement platform, and a glue strip cutter slidably disposed on the edge of the glue strip placement platform. Specifically, when the first paper tube in the paper feeding slot is used up due to printing, the end of the first paper detaches from the first core and falls from the paper feeding slot, landing on the glue strip placement platform below, contacting the connecting glue strip (glued on one side, with the glued side facing upward) on the glue strip placement platform and partially adhering to it; then, the end of the first paper, with the partially adhesive connecting glue strip behind it, moves past the front end of the second paper, where the connecting glue strip adheres to the second paper, connecting the end of the first paper to the front end of the second paper, and the printing operation continues, achieving the effect of continuous paper feeding and continuous printing.

[0018] By adopting the above technical solution, when the first paper tube is consumed, the end of the first paper falls and sticks to the connecting strip placed below, which drives the connecting strip to move and stick to the front end of the second paper, thus completing the paper connection action of the first and second paper. The pressure roller of the continuous paper feeding channel can further press the first paper, the second paper and the connecting strip together, thereby enhancing the connection stability of the first and second paper.

[0019] As an improvement, the existing paper feeding area includes a support frame located above the continuous paper feeding channel; it also includes a movable paper feeding platform, which is rotatably connected to the support frame; the movable paper feeding platform is provided with a paper feeding slot, and the first core is rotatably disposed in the paper feeding slot.

[0020] Specifically, the support frame is arranged on both sides above the continuous paper feeding channel, and the movable paper feeding platform is rotatably connected between the support frame, that is, above the continuous paper feeding channel; the paper feeding slot matches the two ends of the first core, so that the first paper falls into the continuous paper feeding channel when the first paper tube rotates.

[0021] By adopting the above technical solution, staff can manually operate the movable paper feeding platform, flip the movable paper feeding platform to tilt the paper feeding slot and pour out the remaining first core, and then manually flip the movable paper feeding platform in the opposite direction to reset it.

[0022] As an improvement, the first replacement component includes a first replacement motor that is drivenly connected to the movable paper feeding platform, and also includes a discharge guide rail that is inclined, with the higher end of the discharge guide rail extending below the paper feeding slot and the lower end of the discharge guide rail extending to a collection container for collecting the first core.

[0023] Specifically, when the first replacement motor rotates, it drives the movable paper feeding platform to flip up and down, causing the paper feeding slot to fall and tilt until the first core in the paper feeding slot slides out of the slot. After that, the first replacement motor drives the movable paper feeding platform to flip in the opposite direction to return to its original position. After the first core slides out of the paper feeding slot, it is caught by the unloading guide rail and slides down from the upper end of the unloading guide rail until it enters the collection container.

[0024] By adopting the above technical solution, the existing paper feeding area can start the first replacement motor after the first paper tube is used up, flip the movable paper feeding platform so that the remaining first core slides out of the paper feeding slot and is guided into the collection container by the unloading guide rail. The first replacement motor will also drive the movable paper feeding platform to reset, ready to welcome the second paper tube to replace the used first paper tube.

[0025] As an improvement, the pre-feeding chute of the pre-feeding area includes two parallel and opposite pre-feeding guide rails. The pre-feeding guide rails match the two ends of the second core and allow the two ends of the second core to slide on the pre-feeding guide rails. The pre-feeding slot is set on the pre-feeding guide rails, and the second core is rotatably set in the pre-feeding slot.

[0026] By adopting the above technical solution, the pre-slide chute allows the second paper roll, which slides along the pre-slide guide rail, to slide into the current paper feed area to replace the first paper roll. Additionally, the pre-slide chute can temporarily store the second paper roll, preventing it from entering the current paper feed area before the first paper roll has been used up.

[0027] As an improvement, the second replacement component includes a blocking block movably mounted on the pre-feeding guide rail. The blocking block is connected to a second replacement motor and, driven by the motor, can prevent the second core from moving towards the current paper feeding area or release the obstruction. The pre-feeding guide rail is inclined to guide the second core to slide towards the current paper feeding area. Specifically, the blocking block is strip-shaped and positioned within a groove in the pre-feeding guide rail. The second replacement motor can rotate the blocking block to an upright position, thereby preventing the second core from moving towards the current paper feeding area and simultaneously forming a pre-feeding slot with the pre-feeding guide rail. The second replacement motor can then rotate the blocking block from the upright position to a releasing position, at which point the blocking block lies flat and retracts into the groove, releasing the obstruction of the second core.

[0028] By adopting the above technical solution, when the current paper feeding area removes the first core from the paper feeding slot and resets the paper feeding slot, the second replacement motor can drive the blocking block to rotate from the upright state to the release state, guiding the second core to slide down due to the tilt of the guide rail, so that the second paper tube slides towards the current paper feeding area and finally reaches the paper feeding slot to replace the first paper tube.

[0029] As an improvement, the paper storage area includes a paper storage compartment with its bottom inclined and the lower end of the bottom of the paper storage compartment extending toward the preparation slot. A third paper tube is placed inside the paper storage compartment, and a barrier component is provided between the preparation slot and the paper storage compartment.

[0030] By adopting the above technical solution, the third paper tube in the paper supply area is blocked by the blocking component and will not fall out of the paper storage compartment. When the blocking component is released, the third paper tube can slide down and leave the paper supply area to reach the prepared slot and replace the original second paper tube.

[0031] As an improvement, the third replacement assembly includes a roller shutter body serving as a blocking member. The roller shutter body includes a rotating shaft parallel to the axis of the third paper tube, and a plurality of blocking rollers arranged around the rotating shaft. The third replacement assembly also includes a third replacement motor, and the rotating shaft is drively connected to the third replacement motor. Specifically, the rotating shaft of the roller shutter body is horizontally positioned, and the blocking rollers are symmetrically distributed around the rotating shaft with respect to its center. The spacing between the blocking rollers is preferably such that the space between adjacent blocking rollers is only sufficient to insert one third paper tube.

[0032] The main purpose of using the roller shutter as a blocking component here is to ensure that only one third paper tube passes through at a time. Other structures that ensure that only one object passes through at a time can also be used instead.

[0033] By adopting the above technical solution, the third replacement motor can drive the blocking roller to rotate through the rotating shaft. Each time it rotates a certain angle, it can release a third paper tube from the storage paper supply area. It will not release two by accident because there is only room for one third paper tube between adjacent blocking rollers. The next third paper tube is blocked behind by the blocking roller.

[0034] Compared with the prior art, the beneficial effects of this utility model are:

[0035] During printing, when the first paper roll in the current paper supply area runs out of paper, the second paper roll extending from the second paper roll in the pre-feed area takes over and continues printing. Then, the first replacement component removes the first paper roll core from the paper supply slot in the current paper supply area, and the second replacement component transfers the second paper roll from the pre-feed area to the paper supply slot in the current paper supply area, thus replacing the used first paper roll. Finally, the third replacement component guides the third paper roll stored in the storage paper supply area to the pre-feed slot in the pre-feed area, replacing the original second paper roll. Since the first, second, and third paper rolls have the same actual structure, the printer can print continuously until the first, second, and all third paper rolls on the continuous paper feeding mechanism are used up. This process eliminates the need for manual replenishment of paper rolls, reducing manpower requirements and improving production efficiency. Attached Figure Description

[0063] Implementation Case 1:

[0064] As attached Figure 1-13 As shown, a rotary printing press for continuous paper feeding and uninterrupted printing includes a printing mechanism 1 and a continuous paper feeding mechanism; the continuous paper feeding mechanism includes a continuous paper feeding channel 2, a current paper feeding area 3, a preparatory paper feeding area 4, a storage paper feeding area 5, and a paper feeding management component;

[0065] The continuous paper feeding channel 2 leads to the printing mechanism 1 at its end and is able to transport printing paper to the printing mechanism 1;

[0066] The existing paper feeding area 3 is provided with a paper feeding frame 301, and a paper feeding slot 302 is movably provided on the paper feeding frame 301. A first paper tube 303 is provided in the paper feeding slot 302. The first paper tube 303 includes a first core 3031 and a first paper material 3032 surrounding the first core 3031. The front end of the first paper material 3032 is guided to the printing mechanism 1 by the continuous paper feeding channel 2.

[0067] The pre-feeding area 4 is provided with a pre-slide chute, and a pre-slot 405 is provided on the pre-slide chute. A second paper tube 402 is provided in the pre-slot 405. The second paper tube 402 includes a second core 4021 and a second paper material 4022 surrounding the second core 4021. The front end of the second paper material 4022 extends to the end of the continuous paper feeding channel 2 to replace the first paper material 3032.

[0068] The storage and paper supply area 5 stores a third paper tube 501 and is also provided with a blocking member 503 to prevent the third paper tube 501 from entering the pre-supply area 4; the third paper tube 501 includes a third core 5011 and a third paper material 5012 surrounding the third core 5011.

[0069] Specifically, the first paper tube 303, the second paper tube 402, and the third paper tube 501 have the same structure. The distinction is made here because they are located in different structures and production processes.

[0070] The paper supply management component includes a first replacement component for removing a first core 3031 without first paper 3032, a second replacement component for transferring a second paper tube 402 that has replaced the first paper 3032 to the current paper supply area 3, and a third replacement component for guiding a third paper tube 501 to the preparatory paper supply area 4.

[0071] During printing operations, when the first paper tube 303 in the current paper supply area 3 runs out of the first paper material 3032, the second paper material 4022 extending from the second paper tube 402 in the preparatory paper supply area 4 first takes over the first paper material 3032 to continue printing; then the first replacement component removes the first core 3031 from the paper supply slot 302 in the current paper supply area 3, and the second replacement component transfers the second paper tube 402 located in the preparatory paper supply area 4 to the paper supply slot 302 in the current paper supply area 3, so that the second paper tube 402 takes over the used first paper tube 303; the third replacement component guides the third paper tube 501 stored in the storage paper supply area 5 to the preparatory slot 405 in the preparatory paper supply area 4, so that the third paper tube 501 takes over the original second paper tube 402. Since the actual structures of the first paper roll 303, the second paper roll 402, and the third paper roll 501 are the same, the printer can print continuously until the first paper roll 303, the second paper roll 402, and all the third paper rolls 501 on the continuous paper feeding mechanism are used up. This process does not require manual replenishment of paper rolls, reducing the occupation of human resources and improving production efficiency.

[0072] The continuous paper feeding channel 2 is provided with a pressure roller 6 above the position of the printing mechanism 1; the continuous paper feeding channel 2 is provided with a gluing assembly below the current paper feeding area 3. The gluing assembly includes a glue strip placement platform 7 located below the paper feeding slot 302, a glue strip replenishment device 8 located on the side of the glue strip placement platform 7, and a glue strip cutter 9 slidably disposed on the edge of the glue strip placement platform 7. Specifically, when the first paper tube 303 of the paper feed slot 302 is used up due to printing, the end of the first paper 3032 detaches from the first core 3031 and falls from the paper feed slot 302, landing on the adhesive strip placement platform 7 below. It contacts the connecting adhesive strip 10 (with adhesive applied on one side, with the adhesive side facing upward) on the adhesive strip placement platform 7 and partially adheres to it. Then, the end of the first paper 3032, with the partially adhesive connecting adhesive strip 10 facing upward, moves past the front end of the second paper 4022. The connecting adhesive strip 10 adheres to the second paper 4022, so that the end of the first paper 3032 connects to the front end of the second paper 4022, and the printing operation continues, achieving the effect of continuous paper feeding and continuous printing.

[0073] When the first paper roll 303 is consumed, the end of the first paper 3032 falls and sticks to the adhesive strip placed below, causing the adhesive strip to move and stick to the front end of the second paper 4022, completing the paper receiving action of the first paper 3032 and the second paper 4022. The pressure roller 6 of the continuous paper feeding channel 2 can further press the first paper 3032, the second paper 4022 and the adhesive strip together, thereby enhancing the connection stability of the first paper 3032 and the second paper 4022.

[0074] The paper feeding frame 301 of the current paper feeding area 3 includes a support frame 3011 located above the continuous paper feeding channel 2; it also includes a movable paper feeding platform 3012, which is rotatably connected to the support frame 3011 by flipping up and down; the movable paper feeding platform 3012 is provided with a paper feeding slot 302, and the first core 3031 is rotatably disposed in the paper feeding slot 302.

[0075] Specifically, the support frame 3011 is arranged on both sides above the continuous paper feeding channel 2, and the movable paper feeding platform 3012 is rotatably connected between the support frame 3011, that is, above the continuous paper feeding channel 2; the paper feeding slot 302 matches the two ends of the first core 3031, so that when the first paper tube 303 rotates, the first paper 3032 falls into the continuous paper feeding channel 2.

[0076] The operator is allowed to manually operate the movable paper feeding platform 3012, flip the movable paper feeding platform 3012 to tilt the paper feeding slot 302 and pour out the remaining first core 3031, and then manually flip the movable paper feeding platform 3012 in the opposite direction to reset it.

[0077] The first replacement component includes a first replacement motor 304 that is drivenly connected to the movable paper feeding platform 3012, and also includes a discharge guide rail 305. The discharge guide rail 305 is inclined, with its higher end extending below the paper feeding slot 302 and its lower end extending to a collection container for collecting the first core 3031.

[0078] Specifically, when the first replacement motor 304 rotates, it can drive the movable paper feeding platform 3012 to rotate up and down, thereby causing the paper feeding slot 302 to fall and tilt until the first core 3031 in the paper feeding slot 302 slides out of the paper feeding slot 302. After that, the first replacement motor 304 can drive the movable paper feeding platform 3012 to rotate in the opposite direction to return to its original position. After the first core 3031 slides out of the paper feeding slot 302, it is received by the unloading guide rail 305 and slides down from the upper end of the unloading guide rail 305 until it enters the collection container.

[0079] After the first paper roll 303 is used up, the current paper supply area 3 can start the first replacement motor 304 to flip the movable paper supply platform 3012 so that the remaining first core 3031 slides out of the paper supply slot 302 and is guided into the collection container by the unloading guide rail 305. The first replacement motor 304 will also drive the movable paper supply platform 3012 to reset, ready to welcome the second paper roll 402 to replace the used first paper roll 303.

[0080] The pre-feeding area 4 includes two parallel and opposite pre-guide rails 401. The pre-guide rails 401 match the two ends of the second core 4021 and allow the two ends of the second core 4021 to slide on the pre-guide rails 401. The pre-slot 405 is provided on the pre-guide rails 401, and the second core 4021 is rotatably disposed in the pre-slot 405.

[0081] The preparatory chute allows the second paper roll 402 to slide into the current paper feed area 3 to replace the first paper roll 303, relying on the second core 4021 that slides on the preparatory guide rail 401. In addition, the preparatory slot 405 can temporarily store the second paper roll 402 to prevent the second paper roll 402 from entering the current paper feed area 3 before the first paper roll 303 is used up.

[0082] The second replacement component includes a blocking block 403 movably mounted on the preparatory guide rail 401. The blocking block 403 is connected to the second replacement motor 404 and, driven by the second replacement motor 404, can prevent the second core 4021 from moving towards the current paper feeding area 3 or release the obstruction of the second core 4021. The preparatory guide rail 401 is inclined to guide the second core 4021 to slide towards the current paper feeding area 3. Specifically, the blocking block 403 is strip-shaped and disposed in the groove of the preparatory guide rail 401. The second replacement motor 404 can drive the blocking block 403 to rotate to an upright state, thereby preventing the second core 4021 from moving towards the current paper feeding area 3, and also forming a preparatory slot 405 with the preparatory guide rail 401. The second replacement motor 404 can drive the blocking block 403 from the upright state to the release state. At this time, the blocking block 403 lies flat and retracts into the groove, releasing the obstruction of the second core 4021.

[0083] When the current paper feeding area 3 removes the first core 3031 from the paper feeding slot 302 and resets the paper feeding slot 302, the second replacement motor 404 can drive the blocking block 403 to rotate from the upright state to the release state, guiding the second core 4021 to slide down due to the tilt of the guide rail, so that the second paper tube 402 slides into the current paper feeding area 3 and finally reaches the paper feeding slot 302 to replace the first paper tube 303.

[0084] The paper storage and supply area 5 includes a paper storage compartment. The bottom of the paper storage compartment is inclined, and the lower end of the bottom of the paper storage compartment extends toward the preparation slot 405. A third paper tube 501 is placed in the paper storage compartment. A blocking member 503 is provided between the preparation slot 405 and the paper storage compartment.

[0085] The third paper tube 501 in the storage and paper supply area 5 is blocked by the blocking member 503 and will not fall out of the paper storage compartment. When the blocking member 503 is released, the third paper tube 501 can slide down and leave the storage and paper supply area 5, reach the prepared slot 405, and replace the original second paper tube 402.

[0086] The third replacement assembly includes a roller shutter body serving as a blocking member. The roller shutter body includes a rotating shaft 5031 parallel to the axis of the third paper tube 501, and a plurality of blocking rollers 5032 arranged around the rotating shaft 5031. The third replacement assembly also includes a third replacement motor 5033, and the rotating shaft 5031 is driveably connected to the third replacement motor 5033. Specifically, the rotating shaft 5031 of the roller shutter body is horizontally arranged, and the blocking rollers 5032 are symmetrically distributed around the rotating shaft 5031. The spacing of the blocking rollers 5032 is preferably such that the space between adjacent blocking rollers 5032 is only sufficient to insert one third paper tube 501.

[0087] The third replacement motor 5033 can drive the blocking roller 5032 to rotate via the rotating shaft 5031. Each rotation at a certain angle can release a third paper tube 501 from the paper storage area 5. It will not release two by accident because there is only room for one third paper tube 501 between adjacent blocking rollers 5032. The next third paper tube 501 is blocked behind by the blocking roller 5032.

[0088] In summary, after reading this utility model document, those skilled in the art can make various other corresponding modifications based on the technical solution and concept of this utility model without creative mental effort. Different application scenarios are all within the scope of protection of this utility model.
