Description

Technical Field

[0001] This utility model relates to a fast feeding and clamping device for printing lines, belonging to the field of printing line technology. Background Technology

[0002] In the printing line production process, the feeding and clamping of the paper roll is a crucial step in ensuring printing continuity and stability. Traditional printing lines typically use a gear-driven transmission structure for the paper roll, with a drive component rotating the roll to transport it. However, during paper roll feeding, the gear at the end of the roll must directly mesh with the gear on the support frame, which can easily lead to rigid collisions between the gear teeth, causing gear wear and severely reducing the equipment's lifespan. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fast feeding clamping device for printing lines, which solves the problem in the prior art that the gear at the end of the paper roll needs to be directly meshed with the gear on the support frame, which is very easy to cause rigid collision of the gear tooth surface, resulting in gear wear and seriously reducing the service life of the equipment.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: A printing line quick feeding clamping device includes a support frame, a fixed groove on the support frame, a placement groove communicating with the fixed groove on the support frame, a rotating shaft inside the placement groove, a roll of paper sleeved on the outer surface of the rotating shaft, one end of the rotating shaft extending into the interior of the fixed groove and fixedly mounted with a driven gear, a driving gear on one side of the driven gear, an idler gear between the driving gear and the driven gear, a driving structure for driving the driving gear on the support frame, a limiting hole at one end of the rotating shaft located in the fixed groove, a limiting rod on the support frame, a fixed rod fixedly mounted on the limiting rod, a fixed shaft fixedly mounted at the end of the fixed rod away from the limiting rod, the fixed shaft and the idler gear being rotatably mounted, and a pushing structure for pushing the limiting rod to insert into the limiting hole on the support frame.

[0005] By adopting the above technical solution, firstly, the pushing structure moves the limiting rod, which in turn moves the fixed rod and fixed shaft. This causes the fixed shaft to move the idler gear within the fixed groove, achieving misalignment between the idler gear and the driven gear. Then, the rotating shaft moves the driven gear into the interior of the fixed groove, bringing it into contact with the inner wall of the groove. Because the idler gear and driven gear are misaligned, rigid collisions between them are avoided during driven gear installation, preventing damage and extending the device's service life. At this point, the limiting hole aligns with the limiting rod. The pushing structure then pushes the limiting rod towards the limiting hole again. The directional movement allows the limiting rod to be inserted into the limiting hole. Simultaneously, under the action of the fixed rod and fixed shaft, the limiting rod drives the idler gear and the driven gear to mesh, thus completing the quick installation and clamping of the rotating shaft. The cooperation of the limiting rod and the limiting hole radially limits the rotating shaft, preventing displacement or shaking during rotation and ensuring stable rotation of the rotating shaft. This, in turn, ensures the normal working state of the paper roll. Then, the start-up drive structure drives the drive gear to rotate. The drive gear, under the action of the idler gear, drives the driven gear to rotate, causing the driven gear to drive the rotating shaft to rotate, and the rotating shaft to drive the paper roll to rotate.

[0006] The present invention is further configured such that: the pushing structure includes a mounting block, a mounting groove, a mounting plate, a sliding rod, and a lever plate; the mounting block is fixedly connected to the support frame; the mounting groove is opened on the mounting block and communicates with the fixed groove; the mounting plate is slidably disposed inside the mounting groove; the limiting rod is fixedly connected to the end of the mounting plate facing the fixed groove; the end of the limiting rod away from the mounting plate can extend into the interior of the fixed groove and be inserted into the limiting hole; the sliding rod is fixedly disposed on the end of the mounting plate away from the limiting rod; the end of the sliding rod away from the mounting plate extends to the outside of the mounting block and is fixedly connected to the lever plate.

[0007] The present invention is further configured such that: a first spring is provided between the end of the mounting plate away from the limiting rod and the inner wall of the mounting groove, the first spring is sleeved on the outside of the sliding rod, and the two ends of the first spring are respectively fixedly connected to the inner wall of the mounting groove and the mounting plate.

[0008] By adopting the above technical solution, pulling the lever moves the sliding rod, which in turn moves the mounting plate in the mounting groove. The mounting plate moves the limiting rod away from the limiting hole, thus separating the limiting rod from the limiting hole. When the mounting plate moves, it compresses the first spring, thereby removing the limit on the rotating shaft and facilitating the disassembly of the rotating shaft for replacement of the paper roll.

[0009] The present invention is further configured such that: a first positioning groove is provided on the inner wall of the mounting groove, and a first positioning block is fixedly provided on the mounting plate, the first positioning block being slidably disposed with the first positioning groove.

[0010] The present invention is further configured such that: the drive structure includes a motor, a rotating shaft, a sliding groove, a connecting shaft, and a connecting plate; the motor is fixedly mounted on the support frame; the rotating shaft is poweredly connected to the motor; the sliding groove is opened on the rotating shaft; the connecting shaft is located inside the sliding groove; one end of the connecting shaft extends to the outside of the rotating shaft and is fixedly connected to the connecting plate; and the drive gear is fixedly connected to the connecting plate.

[0011] By adopting the above technical solution, the starting motor drives the rotating shaft to rotate, which in turn drives the connecting shaft to rotate, which in turn drives the connecting plate to rotate, which in turn drives the drive gear to rotate.

[0012] The present invention is further configured such that: a second positioning groove is provided on the inner wall of the sliding groove, a second positioning block is fixedly provided on the outer side of the connecting shaft, the second positioning block is slidably disposed with the second positioning groove, and a second spring is fixedly provided between one end of the connecting shaft located in the sliding groove and the inner wall of the sliding groove.

[0013] The present invention is further configured such that a protective cover is hinged to the support frame, and the protective cover is used to close the fixing groove.

[0014] The beneficial effects of this utility model are as follows: First, the pushing structure drives the limiting rod to move, which in turn drives the fixed rod and fixed shaft to move. This causes the fixed shaft to move the idler gear within the fixed groove, achieving misalignment between the idler gear and the driven gear. Then, the rotating shaft drives the driven gear to move into the interior of the fixed groove, making the rotating shaft abut against the inner wall of the groove. Because the idler gear and driven gear are misaligned, rigid collisions between the driven gear and the idler gear are avoided during the installation of the driven gear, preventing damage to the gear and extending the service life of the device. At this point, the limiting hole is aligned with the limiting rod. The pushing structure then pushes the limiting rod towards the limiting hole, thus achieving the desired alignment. The rod is inserted into the limiting hole. At the same time, the limiting rod, under the action of the fixed rod and the fixed shaft, drives the idler gear and the driven gear to mesh, thus completing the quick installation and clamping of the rotating shaft. The limiting rod and the limiting hole work together to radially limit the rotating shaft, preventing displacement or shaking during rotation and ensuring stable rotation of the rotating shaft. This ensures the normal working state of the paper roll. Then, the drive structure is activated to drive the drive gear to rotate. The drive gear, under the action of the idler gear, drives the driven gear to rotate, causing the driven gear to drive the rotating shaft to rotate. The rotating shaft drives the paper roll to rotate and is then conveyed by an external conveying mechanism. Attached Figure Description

[0023] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] like Figures 1 to 6As shown, a rapid feeding and clamping device for a printing line includes a support frame 1 connected to an external conveying mechanism. A fixed groove 2 is vertically formed on the support frame 1, and a placement groove 3 communicating with the fixed groove 2 is also formed on the support frame 1. The support frame 1 also has an assembly groove and a placement groove 3 corresponding to the fixed groove 2. A rotating shaft 4 is disposed inside the placement groove 3, and a roll of paper 10 is sleeved on the outer surface of the rotating shaft 4. One end of the rotating shaft 4 extends into the interior of the fixed groove 2 and is fixedly mounted with a driven gear 5. The other end of the rotating shaft 4 is installed inside the assembly groove through the corresponding placement groove 3. A driving gear 6 is disposed on one side of the driven gear 5. The driving gear 6 and... An idler gear 7 is provided between the driven gears 5. A drive structure for driving the driving gear 6 is provided on the support frame 1. A limit hole 8 is opened at one end of the rotating shaft 4 located in the fixed groove 2. The limit hole 8 is opened along the axial direction of the rotating shaft 4. A limit rod 9 is provided on the support frame 1. A fixed rod 1061 is fixedly provided on the limit rod 9. The fixed rod 1061 extends in the fixed groove 2 toward the idler gear 7. A fixed shaft 1062 is fixedly provided at the end of the fixed rod 1061 away from the limit rod 9. The fixed shaft 1062 is rotatably connected with the idler gear 7. A push structure for pushing the limit rod 9 to insert into the limit hole 8 is also provided on the support frame 1.

[0025] like Figure 4 As shown, the pushing structure includes a mounting block 1011, a mounting groove 1012, a mounting plate 1013, a sliding rod 1014, and a lever 1015. The mounting block 1011 is fixedly connected to the support frame 1. The mounting groove 1012 is horizontally opened on the mounting block 1011 and communicates with the fixed groove 2. The mounting plate 1013 is slidably disposed inside the mounting groove 1012 and slides along the opening direction of the mounting groove 1012. The limiting rod 9 is fixedly connected to the end of the mounting plate 1013 facing the fixed groove 2. The end of the limiting rod 9 away from the mounting plate 1013 can extend into the interior of the fixed groove 2 and be inserted into the limiting hole 8. The sliding rod 1014 is fixedly disposed on the end of the mounting plate 1013 away from the limiting rod 9. The end of the sliding rod 1014 away from the mounting plate 1013 extends to the outside of the mounting block 1011 and is fixedly connected to the lever 1015. A first spring 1021 is provided between the end of the mounting plate 1013 furthest from the limiting rod 9 and the inner wall of the mounting groove 1012. The first spring 1021 is in a tensioned state when not under force. The first spring 1021 is sleeved on the outside of the sliding rod 1014, and the two ends of the first spring 1021 are fixedly connected to the inner wall of the mounting groove 1012 and the mounting plate 1013, respectively. A first positioning groove 1031 is provided on the inner wall of the mounting groove 1012. The opening direction of the first positioning groove 1031 is the same as that of the mounting groove 1012. A first positioning block 1032 is fixedly provided on the mounting plate 1013. The first positioning block 1032 is slidably disposed with the first positioning groove 1031, and the first positioning block 1032 moves synchronously with the mounting plate 1013.

[0026] like Figures 5 to 7 As shown, the drive structure includes a motor 1041, a rotating shaft 1042, a sliding groove 1043, a connecting shaft 1044, and a connecting plate 1045. The motor 1041 is fixedly mounted on the support frame 1 and is connected to an external power source to provide power to the motor 1041. The rotating shaft 1042 is poweredly connected to the motor 1041 and extends toward the fixed groove 2. The sliding groove 1043 is formed on the rotating shaft 1042 and extends along the axial direction of the rotating shaft 1042. The connecting shaft 1044 is located inside the sliding groove 1043, and one end of the connecting shaft 1044 extends to the outside of the rotating shaft 1042 and is fixedly connected to the connecting plate 1045. The drive gear 6 is fixedly connected to the connecting plate 1045. A second positioning groove 1051 is provided on the inner wall of the sliding groove 1043. The opening direction of the second positioning groove 1051 is the same as that of the sliding groove 1043. A second positioning block 1052 is fixedly provided on the outer side of the connecting shaft 1044. The second positioning block 1052 is slidably disposed with the second positioning groove 1051. A second spring 1053 is fixedly provided between one end of the connecting shaft 1044 located in the sliding groove 1043 and the inner wall of the sliding groove 1043. The second spring 1053 is in a tensioned state when it is not under force. The second positioning block 1052 moves synchronously with the connecting shaft 1044.

[0027] like Figure 1 As shown, a protective cover 1071 is hinged to the support frame 1. The protective cover 1071 is used to close the fixing groove 2. By closing the fixing groove 2 with the protective cover 1071, personnel are prevented from accidentally contacting rotating gears and other parts, thereby improving the safety during the use of the equipment.

[0028] First, the limiting rod 9 is moved by the pushing structure. The limiting rod 9 moves the fixed rod 1061 and the fixed shaft 1062, causing the fixed shaft 1062 to move the idler gear 7 within the fixed groove 2, thus achieving misalignment between the idler gear 7 and the driven gear 5. Then, the rotating shaft 4 moves the driven gear 5 into the interior of the fixed groove 2, so that the rotating shaft 4 abuts against the inner wall of the placement groove 3. Because the idler gear 7 and the driven gear 5 are misaligned, rigid collisions between the driven gear 5 and the idler gear 7 are avoided during the installation of the driven gear 5, preventing damage to the gears and extending the service life of the device. At this point, the limiting hole 8 is aligned with the limiting rod 9. The limiting rod 9 is then pushed towards the limiting hole 8 by the pushing structure again, so that the limiting rod 9 is inserted into the limiting position. Inside hole 8, the limiting rod 9, under the action of the fixed rod 1061 and the fixed shaft 1062, drives the idler gear 7 to mesh with the driven gear 5, thus completing the quick installation and clamping of the rotating shaft 4. Through the cooperation of the limiting rod 9 and the limiting hole 8, the rotating shaft 4 is radially limited to prevent displacement or shaking during rotation, ensuring the stable rotation of the rotating shaft 4, thereby ensuring the normal working state of the paper roll 10. Then, the starting drive structure drives the driving gear 6 to rotate. The driving gear 6, under the action of the idler gear 7, drives the driven gear 5 to rotate, causing the driven gear 5 to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the paper roll 10 to rotate and then conveys the paper roll 10 through the external conveying mechanism.

[0029] When the rotating shaft 4 needs to be replaced, first pull the lever 1015 to move the sliding rod 1014, so that the sliding rod 1014 moves the mounting plate 1013 in the mounting groove 1012. The mounting plate 1013 moves the limiting rod 9 away from the limiting hole 8. At this time, the limiting rod 9 moves the fixing rod 1061 and the fixing shaft 1062, so that the fixing shaft 1062 moves the idler gear 7 in the fixing groove 2, realizing the misalignment of the idler gear 7 and the driven gear 5. When the mounting plate 1013 moves, it will compress the first spring 1021, so that the limiting rod 9 and the limiting hole 8 are separated. The limiting of the rotating shaft 4 and the abutment engagement of the driven gear 5 can be canceled. Then the rotating shaft 4 can be disassembled, so that the paper roll 10 can be replaced.

[0030] Pulling the lever 1015 moves the sliding rod 1014, causing the sliding rod 1014 to move the mounting plate 1013 in the mounting groove 1012, and the mounting plate 1013 moves the limiting rod.

[0031] When the limiting rod 9 drives the idler gear 7 to move via the fixed rod 1061 and the fixed shaft 1062, the idler gear 7 synchronously pushes the connecting plate 1045 to move. Under the action of abutting against the idler gear 7, the connecting plate 1045 drives the connecting shaft 1044 to slide in the sliding groove 1043. At the same time, the connecting shaft 1044 compresses the second spring 1053 during the movement, causing the connecting shaft 1044 to be housed inside the sliding groove 1043. Simultaneously, the connecting plate 1045 also drives the driving gear 6 to move. At this time, the driven gear 5 is installed into the fixed groove 2 via the rotating shaft 4. Then, the lever 1015 is released, and the first spring 102... 1. The reset pushes the limiting rod 9 to move towards the limiting hole 8, so that the limiting rod 9 is inserted into the limiting hole 8. At the same time, the second spring 1053 resets and pushes the connecting shaft 1044 to move, so that the connecting shaft 1044 drives the connecting plate 1045 and the driving gear 6 to move. At the same time, under the pushing action of the fixed shaft 1062 and the connecting plate 1045, the idler gear 7 and the driven gear 5 are engaged. When feeding the paper roll 10, the idler gear 7 and the driving gear 6 are always engaged, avoiding the situation where the idler gear 7 disengages from both the driving gear 6 and the driven gear 5 at the same time. This allows the idler gear 7 to quickly engage with the driven gear 5, improving the feeding efficiency.

[0032] The starting motor 1041 drives the rotating shaft 1042 to rotate, which in turn drives the connecting shaft 1044 to rotate. The connecting shaft 1044 then drives the connecting plate 1045 to rotate, which in turn drives the drive gear 6 to rotate.

[0033] The limit stroke of the fixing rod 1061 in the fixing groove 2 is the same as the stroke of the limiting rod 9 in the limiting hole 8, so as to avoid the fixing rod 1061 from getting stuck against the inner wall of the fixing groove 2. During the movement of the mounting plate 1013, the cooperation of the first positioning block 1032 and the first positioning groove 1031 prevents the mounting plate 1013 from rotating in the mounting groove 1012. During the sliding process, the connecting shaft 1044 is positioned and guided by the cooperation of the second positioning block 1052 and the second positioning groove 1051. At the same time, the rotating shaft 1042 will drive the connecting shaft 1044 to rotate synchronously with the cooperation of the second positioning block 1052 and the second positioning groove 1051, so as to avoid the connecting shaft 1044 from spinning freely.
