[0002] Labels typically need to be rolled up after production for storage and transportation.

[0003] In current equipment used for winding label paper, an air shaft is generally used to clamp the paper tube and then wind the label paper onto the paper tube. However, this clamping method makes it difficult to control the left and right position of the paper tube, and it is prone to misalignment. In addition, the air shaft is expensive, complex in structure, and difficult to maintain. To solve the above problems, a label winding device for label production is disclosed in application number CN202320290883.9. In this device, an adjusting plate is set to press the paper tube onto the movable block, thereby driving the paper tube to rotate and adjust its position, eliminating the need for an air shaft. However, this device has certain drawbacks, such as the need to remove the right support plate before disassembling and assembling the paper tube, which is cumbersome. Therefore, improvements are needed. Utility Model Content

[0018] Reference Figures 1-5According to an embodiment of the positioning and winding device of the present invention, it includes a base plate 11, a fixing plate 12 mounted on the base plate 11, an inner support shaft 13 rotatably connected inside the fixing plate 12, a winding drum 14 sleeved on the inner support shaft 13, and a fixing mechanism for clamping the outer paper tube sleeved on the winding drum 14. A drive box 15 is fixed on the fixing plate 12, and a No. 1 motor 16 for driving the inner support shaft 13 to rotate is installed inside the drive box 15.

[0019] When the winding operation is performed, the worker puts the paper tube over the winding drum 14 and fixes it with a fixing mechanism. Then, the No. 1 motor 16 drives the inner support shaft 13 and the winding drum 14 to rotate, thereby enabling the winding operation.

[0020] In order to ensure that the inner support shaft 13 and the winding drum 14 can rotate stably after carrying the paper tube and label roll, the base plate 11 is also fixedly provided with a mounting plate 21. A translation plate 22 is slidably connected to the mounting plate 21. A horizontal plate 23 is connected to the left side of the translation plate 22 through a rotating shaft, and a protruding rod 24 is rotatably connected to the left side of the horizontal plate 23. The translation plate 22 is equipped with a driving component for controlling the angle of the horizontal plate 23 by driving the rotating shaft to rotate. The mounting plate 21 is equipped with a first cylinder 25 for controlling the left and right position of the translation plate 22. The right end face of the inner support shaft 13 is provided with an insertion hole 26 for accommodating the protruding rod 24.

[0021] The first cylinder 25 can control the lateral movement of the translation plate 22, the horizontal plate 23 and the protruding rod 24. When the protruding rod 24 is aligned with the insertion hole 26, the first cylinder 25 can control the protruding rod 24 to enter and exit the insertion hole 26. When the protruding rod 24 is inserted into the insertion hole 26, it can provide support for the right end of the inner support shaft 13. When it is necessary to disassemble or assemble the paper tube, the operator controls the translation plate 22 to move to the right through the first cylinder 25, thereby causing the protruding rod 24 to leave the insertion hole 26. Then, the operator controls the horizontal plate 23 to swing at a certain angle through the driving component to avoid interfering with the disassembly and assembly of the paper tube on the winding drum 14.

[0022] In this embodiment, the driving component is a second motor 27 fixed on the translation plate 22. The output shaft of the second motor 27 is connected to the rotating shaft. The second motor 27 needs to have a self-locking function to prevent it from falling after power failure. Similarly, the driving component can also be a rotary cylinder, which can achieve the same technical purpose.

[0023] The fixing mechanism includes a left push cylinder assembly and a right support assembly; The left pusher assembly includes a slide plate 31 that is slidably connected to the base plate 11. A vertical plate 32 is fixed on the slide plate 31, and a rotating ring 33 is rotatably connected inside the vertical plate 32. The rotating ring 33 is sleeved on the take-up drum 14. A No. 3 motor 34 is installed in the drive box 15. The output shaft of the No. 3 motor 34 is connected to a threaded shaft 91, and the threaded shaft 91 is threadedly connected to the slide plate 31. The right support assembly includes two mounting slots 41 symmetrically distributed within the curved surface of the inner support shaft 13. A baffle 42 is hinged within the mounting slot 41. A sliding groove is provided within the baffle 42, and a pin 43 is slidably connected within the sliding groove. A control plate 44 is mounted on the end of the pin 43 extending outside the baffle 42. A spring is installed between the control plate 44 and the end face of the baffle 42. A slot adapted to the pin 43 and opening into the insertion hole 26 is provided on the side of the mounting slot 41.

[0024] During the paper tube clamping operation, the operator pulls the control plate 44 outward, causing the pin 43 to disengage from the slot. Then, the baffle 42 is brought into a parallel state. At this time, the baffle 42 will not obstruct the installation or removal of the paper tube fitted on the take-up drum 14. After the operation is completed, the operator moves the baffle 42 and makes it perpendicular to the inner support shaft 13. At this time, the pin 43 will be inserted into the slot under the action of the spring to complete the angle locking operation. Then, the slide plate 31 moves to the right, causing the rotating ring 33 to press on the left end of the paper tube and press the paper tube onto the baffle 42 to complete the clamping and locking operation of the paper tube. In this state, the inner support shaft 13 can drive the paper tube to rotate through the take-up drum 14, the baffle 42 and the rotating ring 33.

[0025] It should be noted that there needs to be a certain amount of friction between the baffle 42 and the mounting groove 41 to prevent it from falling directly due to gravity when it is retracted into the mounting groove 41.

[0026] In a second embodiment of the positioning and winding device, in order to adapt to more paper tube sizes, the winding tube 14 can be replaced with different outer diameters, and in this embodiment, such as Figure 2 As shown, the inner diameter of the swivel ring 33 is larger than the outer diameter of the winding drum 14, and a boss 51 is integrally formed on the outer curved surface of the swivel ring 33. A locking plate 52 is slidably connected inside the boss 51, and a push ring 53 is installed at the end of the locking plate 52 extending into the swivel ring 33. Fasteners for locking the position of the locking plate 52 are also provided on the side of the boss 51, and two sets of the boss 51, the locking plate 52 and the push ring 53 are provided, one above the other.

[0027] In this embodiment, when the paper tube is clamped, the operator selects and installs the take-up drum 14 with a suitable outer diameter according to the inner diameter of the paper tube. This ensures that when the paper tube is clamped, the inner wall of the paper tube fits against the outer curved surface of the take-up drum 14, avoiding the slippage and unstable rotation caused by the misalignment of the paper tube and the take-up drum 14. After the take-up drum 14 is installed, the operator can adjust the position of the locking plate 52 and the push ring 53 according to the outer diameter of the take-up drum 14, so that the push ring 53 is close to but not against the take-up drum 14. When the slide plate 31 moves to the right and fixes the position of the paper tube, the push ring 53 replaces the rotating ring 33 in the first embodiment to press against the paper tube and fix it. In this embodiment, the inner and outer positions of the push ring 53 are adjustable to adapt to different specifications of the take-up drum 14 and paper tube.

[0028] The connection between the take-up drum 14 and the inner support shaft 13 is as follows: the inner support shaft 13 is provided with an abutment plate 61 that abuts against the left end of the take-up drum 14; the outer curved surface of the inner support shaft 13 is provided with a transversely extending protrusion; and the inner curved surface of the take-up drum 14 is provided with a transverse groove for accommodating the protrusion. The protrusion and the transverse groove prevent the take-up drum 14 from rotating relative to the inner support shaft 13. The abutment plate 61 is used to position the take-up drum 14 to prevent the take-up drum 14 from pressing against the fixing plate 12.

[0029] To prevent the winding drum 14 from sliding left and right relative to the inner support shaft 13 when the worker moves the wound paper tube to unload, the winding drum 14 is designed with a fixing ring at the left edge of its outer curved surface, and the fixing ring is connected to the abutment plate 61 (not shown in the figure) by fasteners.

[0030] It should be noted that the fastener used to lock the locking plate 52 can be a bolt. The bolt can be pressed directly against the locking plate 52, or it can be pressed against the locking plate 52 by means of a threaded connection to the bolt and a sliding connection to the pressure plate in the boss. This is a conventional setting in the prior art and will not be described in detail here. The winding drum 14 has a notch in its curved surface to accommodate the passage of the baffle 42, and when the baffle 42 is in the upright state, it can extend outside the winding drum 14.

[0031] It should be noted that if the label paper roll is of a smaller diameter, it is not necessary to control the protruding rod 24 to reinforce the inner support shaft 13.

[0032] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
