Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment, specifically a paper roll unwinding machine. Background Technology

[0002] In the paper processing process, the raw paper is wound on a roller and called a paper roll. When the paper needs to be processed, such as slitting, the paper roll must first be transferred to the unwinding mechanism using a crane transfer mechanism and then unwound. This transfer method is limited by the space of the factory, and if the factory does not have a crane transfer mechanism, it will be even more inconvenient to transfer the paper roll to the unwinding mechanism.

[0003] Therefore, it is necessary to provide a paper roll unwinding machine. Summary of the Invention

[0004] The present invention provides a paper roll unwinding carriage, which effectively solves the problem that existing unwinding carriages can only accept paper rolls hoisted by external transfer mechanisms, resulting in low efficiency due to the hoisting process.

[0005] The technical solution adopted in this utility model is:

[0006] A paper roll unwinding carriage includes a base frame, a tray mounted on the base frame, a first linear guide rail and a second linear guide rail arranged along the X direction and symmetrically mounted on the base frame along the tray, a left unwinding mechanism slidably mounted on the first linear guide rail, a right unwinding mechanism slidably mounted on the second linear guide rail, a first drive mechanism fixedly mounted on the base for driving the left unwinding mechanism to slide along the first linear guide rail, and a second drive mechanism for driving the right unwinding mechanism to slide along the second linear guide rail. The left and right unwinding mechanisms are identical. The left unwinding mechanism includes a sliding frame that slides along the first linear guide rail, a lifting frame that slides vertically on the sliding frame, a third drive mechanism fixedly mounted on the sliding frame for driving the lifting frame to rise and fall, a top paper roll rotating assembly mounted on the lifting frame, and a roller shaft rotatably mounted on the lifting frame about the Y-axis as the central axis. The roller shaft is provided with an annular groove for lifting the paper roll, and the tray plate is provided with a lifting groove for lifting the paper roll.

[0007] Furthermore, the base frame includes two No. 1 beams extending along the X direction and several No. 2 beams connecting the No. 1 beams. The two ends of the No. 1 beams are fixedly connected to the upper end faces of the two different No. 1 beams respectively. The roller shaft can extend between the two No. 1 beams so that the upper edge of the roller shaft is lower than the upper end face of the pallet.

[0008] Furthermore, the top paper roll rotating assembly includes a timing belt, a mounting base fixedly mounted on the sliding frame, a top cone head rotatably mounted on the mounting base, a motor mounted on the sliding frame, a drive pulley mounted on the motor's rotating shaft, and a driven pulley coaxially fixedly mounted on the top cone head. The drive pulley and the driven pulley are connected by a timing belt drive.

[0009] Furthermore, the sliding frame is also vertically equipped with a third linear guide rail, the lifting frame is slidably mounted on the third linear guide rail, the third driving mechanism is a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to the lifting frame.

[0010] Furthermore, the annular groove has a circular arc cross-section, and the lifting groove is a circular arc groove.

[0011] Furthermore, each of the lifting frames is provided with at least two rollers arranged along the X direction.

[0012] The beneficial effects of the utility model are: it can eliminate the need for a crane during the paper roll transfer process, and can use a pallet to directly connect with the unwinding table or reference surface for receiving the paper roll, so that the paper roll can be rolled into place in one go, saving working time and improving work efficiency, and making the transfer of paper rolls to the unwinding mechanism no longer restricted by factory space.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown in the embodiment of this application, a paper roll unwinding carriage includes a base frame 1, a tray 2 mounted on the base frame, a first linear guide rail 3 and a second linear guide rail 4 arranged along the X direction and symmetrically mounted on the base frame 1 along the tray 2, a left unwinding mechanism 5 slidably mounted on the first linear guide rail 3, a right unwinding mechanism 6 slidably mounted on the second linear guide rail 4, a first driving mechanism fixedly mounted on the base for driving the left unwinding mechanism 5 to slide along the first linear guide rail 3, and a second driving mechanism fixedly mounted on the base for driving the right unwinding mechanism 6 to move along the second linear guide rail 4. The drive mechanism is the same as the left support unwinding mechanism 5 and the right support unwinding mechanism 6. The left support unwinding mechanism 5 includes a sliding frame 51 that slides with the first linear guide rail 3, a lifting frame 52 that slides vertically on the sliding frame 51, a third drive mechanism 53 that is fixedly mounted on the sliding frame 51 for driving the lifting frame 52 to rise and fall, a top paper roll rotating assembly 54 mounted on the lifting frame 52, and a roller 55 that rotates on the lifting frame 52 with the Y-axis as the central axis. The roller 55 is provided with an annular groove 501 for lifting the paper roll, and the pallet 2 is provided with a lifting groove 201 for lifting the paper roll.

[0018] It should be noted that the diagrams for drive mechanism 1 and drive mechanism 2 are not shown.

[0019] In actual use, the tray 2 connects with the paper roll conveying station or the table of the conveying mechanism, so that the fixture rolls onto the tray 2. Then, the left support unwinding mechanism 5 and the right support unwinding mechanism 6 move synchronously. Taking the left support unwinding mechanism 5 as an example: the lifting frame 52 is driven to move upward by the third drive mechanism 53, so that the annular groove 501 of the roller 55 supports the paper roll until the fixture is raised to the position where it is assembled with the top paper roll rotating assembly 54. Then, the first drive mechanism and the second drive mechanism drive the left support unwinding mechanism 5 and the right support unwinding mechanism 6 to move towards each other. After the roller 55 rolls relative to the paper roll in the X direction, the top paper roll rotating assembly 54 extends into the mounting hole of the paper roll and forms a coaxial fixed connection with the paper roll. Then, the fixed cone head drives the paper roll to rotate to achieve unwinding.

[0020] The above design eliminates the need for a crane during the paper roll transfer process. The pallet 2 can directly connect with the unwinding table or reference surface to receive the paper roll, allowing the paper roll to roll into place in one go. This saves working time, improves work efficiency, and makes the transfer of the paper roll to the unwinding mechanism no longer restricted by factory space.

[0021] Specifically: such as Figure 2 As shown, the base frame 1 includes two first beams 11 extending along the X direction and several second beams 12 connecting the first beams 11. The two ends of the support plate 2 are fixedly connected to the upper end faces of the two different first beams 11 respectively. The roller shaft 55 can extend between the two first beams 11 so that the upper edge of the roller shaft 55 is lower than the upper end face of the support plate 2.

[0022] In actual use, the paper roll rolls from one end of the pallet 2 onto the support groove. Then, the roller 55 lifts the paper roll under the lifting frame 52.

[0023] In the above design, the structural design and specific implementation of the base frame 1 facilitate the installation of the left support unwinding mechanism 5 and the right support unwinding mechanism 6, ensuring the overall structural stability.

[0024] Specifically: such as Figure 1 and Figure 2 As shown, the top paper roll rotating assembly 54 includes a timing belt, a mounting base 542 fixedly mounted on a sliding frame 51, a top cone head 543 rotatably mounted on the mounting base 542, a motor 544 mounted on the sliding frame 51, a drive pulley 545 mounted on the rotating shaft of the motor 544, and a driven pulley 541 coaxially fixedly mounted on the top cone head 543. The drive pulley 545 and the driven pulley 541 are connected by a timing belt drive.

[0025] It should be noted that the top cone head 543 can be a tensioning head, which fixes the paper roll by tensioning, or it can be a key with a convex key, which fixes the paper roll by the keyway of the roll.

[0026] In actual use, after the paper roll is lifted to be coaxial with the top cone 543, taking the left support unwinding mechanism 5 as an example: the left sliding frame 51 moves along the first linear guide rail 3 towards the left end of the paper roll under the drive of the first drive cylinder, so that the top cone 543 extends into the shaft hole of the paper roll and forms a coaxial fixed structure with the paper roll. Then, the motor 544 drives the drive pulley 545 to rotate, and with the cooperation of the synchronous belt, the driven pulley 541 is rotated. Since the driven pulley 541 is coaxially fixedly connected with the top cone 543, when the driven pulley 541 rotates, the top cone 543 drives the paper roll to move synchronously, realizing unwinding.

[0027] In the above design, the structural design and specific implementation of the top paper roll rotating assembly 54 can effectively fix the paper roll quickly and rotate it stably.

[0028] Specifically: such as Figure 1 and Figure 2 As shown, the sliding frame 51 is also vertically provided with a third linear guide rail 56, the lifting frame 52 is slidably disposed on the third linear guide rail 56, the third drive mechanism 53 is a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to the lifting frame 52.

[0029] In actual use, the lifting frame 52 is driven by a hydraulic cylinder to move up and down along the No. 3 linear guide rail 56.

[0030] In the above design, the No. 3 linear guide rail 56 is set to reduce the friction during the lifting process of the lifting frame 52. The hydraulic cylinder has the advantage of sufficient power, which can ensure that the lifting frame 52 can be lifted and lowered stably.

[0031] Specifically: such as Figure 1 and Figure 2 As shown, the annular groove 501 has an arc-shaped cross-section, and the lifting groove 201 is an arc-shaped groove.

[0032] In actual use, when the paper roll is lifted by the roller 55 and the pallet 2, the circular groove 501 and the arc groove can prevent the paper roll from continuing to roll. When the roller 55 rolls relative to the paper roll, the circular groove 501 with the arc cross section can reduce the rolling friction and avoid damage to the paper roll.

[0033] In the above design, the annular groove 501 has a circular arc cross-section and the lifting groove 201 has a circular arc groove, which facilitates the positioning of the paper roll after it is loaded, and at the same time can prevent the roller 55 from damaging the paper roll during the relative rolling process.

[0034] Specifically: such as Figure 1 and Figure 2 As shown, each of the lifting frames 52 is provided with at least two rollers 55, which are arranged along the X direction.

[0035] In the above design, multiple rollers 55 can improve the support for the paper roll and ensure the stability of the paper roll during the lifting process.

[0036] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
