Description

Technical Field

[0001] The invention relates to the technical field of bobbin paper production, in particular to a bobbin paper winding and unwinding device. Background Art

[0002] Paper bobbin is a thin steel paper with tough and wear-resistant texture and smooth surface. After the bobbin paper is made, it needs to be rolled up and stored using a winding and unwinding device.

[0003] The bobbin paper winding and unwinding device generally drives the roller to wind or unwind the base paper through a motor. During this process, the paper roll needs to be tensioned with the tension device to ensure smooth winding and unwinding. In the patent with publication number CN221234859U of the inventor, a spring cooperates with a pressure rod to abut against the paper roll. The spring allows the pressure rod to adaptively follow and abut according to the thickness of the paper roll, thereby solving the tension adjustment problem. However, there is still room for improvement as follows. First, the expansion and contraction characteristics of the spring are utilized to follow and drive the pressure rod when the thickness of the paper roll changes. However, the pressure provided by the spring is not constant under different contraction and expansion lengths, so it is easy for the spring to gradually provide insufficient tension during unwinding and excessive tension during winding. Second, during the winding process, debris is attached to the surface of the paper roll, and direct winding will make the paper roll loose. Therefore, a bobbin paper winding and unwinding device is proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a bobbin paper winding and unwinding device, which has the advantages of being easy to wind and having a good winding effect.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-6 A bobbin paper winding and unwinding device in the present application comprises a workbench 1, on which a longitudinally extending vertical plate 11 is provided, on which a winding mechanism is rotatably provided and a pressure rod 23 is movably provided above the winding mechanism, a mounting shell 2 is fixedly provided on the vertical plate 11, a spring 25 is provided in the mounting shell 2, a follower block 26 sliding in the mounting shell 2 is fixedly provided at the lower end of the spring 25, the follower block 26 abuts against the paper roll on the winding mechanism, a pressure rod 23 is provided in the mounting shell 2 which is lifted and lowered by a driving member, a synchronous sensor 24 is provided on the pressure rod 23, and the synchronous sensor 24 is electrically connected to the follower block 26 and the driving member respectively, so that the pressure rod 23 and the follower block 26 are placed at the same horizontal height to press the paper roll.

[0022] The device is provided with an extension shell 21 on one side of the mounting shell 2. The mounting shell 2 is closed from top to bottom, and the lower part of the extension shell 21 is connected. A spring 25 is arranged in the extension shell 21, and a follower block 26 is provided at the lower end thereof. The follower block 26 extends the shell 21 and contacts the paper roll. When the paper roll becomes thinner, the spring 25 is extended, and when the paper roll becomes thicker, the spring 25 is compressed. In this way, the follower block 26 can be driven to maintain a constant contact state with the paper roll. The pressure rod 23 is driven to rise and fall by the driving member. The driving member can be a screw 22, and the pressure rod 23 is threadedly connected with the screw 22. The pressure rod 23 contacts the inner wall of the mounting shell 2 to limit the pressure. The rod 23 rotates, so that the screw rod 22 can drive the pressure rod 23 to rise and fall when it rotates. A bearing assembly 27 is set at the other end of the pressure rod 23 to follow the rise and fall of the pressure rod 23 to ensure that the pressure rod 23 is balanced. The synchronous sensor 24 on the pressure rod 23 can be a photoelectric sensor or an infrared sensor. A corresponding sensor element is set on the follower block to keep the pressure rod 23 and the follower block 26 at the same height to ensure that the pressure rod 23 has a constant pressure and normally presses the paper roll, avoiding the problem of uneven force supply when the spring 25 changes in length, affecting normal winding.

[0023] Furthermore, a cleaning assembly is rotatably provided on the vertical plate 11, and the cleaning assembly extends to the outer periphery of the paper roll. The cleaning assembly includes a fixed cleaning roller 3 and a movable cleaning roller 31 that swings back and forth around the outer periphery of the paper roll. An arc groove 111 is opened on the vertical plate 11, and the movable cleaning roller 31 is slidably arranged in the arc groove 111. A main gear 25 is sleeved on the outer periphery of the fixed cleaning roller 3, and a planetary gear 34 is meshed with the main gear 25. A sliding rod 33 is fixed at the axis of the planetary gear 34, and also includes a connecting rod 32. The connecting rod 32 is rotatably connected to the sliding rod 33 and the movable cleaning roller 31 respectively, so that the movable cleaning roller 31 swings back and forth as the main gear 25 rotates. In this way, the fixed cleaning roller 3 can rotate to clean the paper roll in the rewinding and unwinding, and the movable cleaning roller 31 can periodically reciprocate and rub the outer periphery of the paper roll to improve the cleaning effect. Moreover, the transmission through the planetary gear 34 does not require an additional driving member to drive, and simultaneously realizes self-rotation cleaning and swing cleaning.

[0024] The device is arranged to drive the fixed cleaning roller 3 to rotate using a motor, and a main gear 25 is sleeved on the fixed cleaning roller 3, and the main gear 25 meshes with the planetary gear 34, so that when the main gear 25 rotates, the planetary gear 34 rotates around its outer circumference, and is driven by the connecting rod 32, and the movable cleaning roller 31 swings back and forth in the arc groove 111, thereby rubbing back and forth on the outer circumference of the paper roll being reeled and unwound to clean impurities.

[0025] Furthermore, a slide rail seat 36 is fixedly disposed on the workbench 1 . A circular slide groove 361 is formed on one side of the slide rail seat 36 facing the slide rod 33 . The slide rod 33 is slidably disposed in the slide groove 361 .

[0026] The device supports the planetary gear 34 to move around the main gear 25 by providing an annular sliding groove 361 that is consistent with the movement trajectory of the planetary gear 34 .

[0027] See also Figure 1 Further, the winding mechanism includes a reel 4, a fixed baffle 41 is fixedly sleeved on the outer periphery of the reel 4, and a movable baffle 43 is slidably sleeved, and the middle portion of the movable baffle 43 can be bent in one direction.

[0028] When in use, the paper roll is sleeved onto the outer periphery of the reel 4 for winding and unwinding. When the paper roll needs to be limited to rotate and prevented from sliding left and right, the device is fixedly provided with a fixed baffle 41 on one side and a movable baffle 43 is slidably sleeved on the other side, so that when loading the paper roll, the movable baffle 43 moves out of the reel 4, allowing the paper roll to be smoothly loaded into the reel 4 and abut against the fixed baffle 41. After loading, the movable baffle 43 is moved back into the movable baffle 43. The movable baffle 43 fits the paper roll so that the two baffles do not prevent the paper roll from rotating, but can limit the paper roll from sliding. The device positions the paper roll by abutting the opposite sides of the two baffles. In order to facilitate the paper roll to be sleeved onto the outer periphery of the reel 4 After the movable baffle 43 is moved out of the reel 4, it can be bent toward the fixed baffle 41 without blocking the paper roll from being connected. After the paper roll is connected, the movable baffle 43 is restored and moved toward the fixed baffle 41 until the two baffles abut the paper roll. Since the movable baffle 43 can only rotate in one direction, it can meet the needs of limiting and positioning the paper roll. The design of driving the movable baffle 43 to move is a prior art, and can be directly driven by a driving member or threadedly connected to the screw rod 42 and limit its rotation tendency, so that the screw rod 42 drives it to move when it rotates. This design is not an innovative invention of this patent and will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
