Then the air shaft is installed on the uncoiler. After the paper roll reaches the specified requirements, a new air shaft is replaced, and the air shaft of the completed wound paper roll is replaced and deflated through the air nozzle at the end face of the shaft. The pressing strip of the air shaft will quickly retract after the air bag is deflated, so as to take out the air shaft from the paper core and prepare for the next winding operation. The whole process is relatively complicated and the loading operation is inconvenient. Content of the Utility Model

Specific implementation manner

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 and Figure 2 , the figure is a preferred implementation manner of the present invention, which discloses a movable arm rotary unwinder. The movable arm rotary unwinder includes a frame 1, a moving assembly and an unwinding assembly.

[0028] A swivel arm main shaft 15 is provided on the frame 1. One end of the swivel arm main shaft 15 passes through the frame 1 and is connected to a swivel arm speed reducer 16. The swivel arm speed reducer 16 is installed on the frame 1. The swivel arm main shaft 15 and its upper components can be driven to rotate by the swivel arm speed reducer 16, which is beneficial to realizing non-stop operation.

[0029] Two moving assemblies are arranged on the main shaft 15 of the rotating arm, and the two moving assemblies are arranged on the front and rear sides of the main shaft 15 of the rotating arm, respectively. Each moving assembly includes a traveling assembly, two moving arms arranged on the main shaft 15 of the rotating arm, and a guide rail 7 installed on the main shaft 15 of the rotating arm. The two moving arms are respectively a first moving arm 11 and a second moving arm 12. The two moving arms in the same moving assembly are arranged at both ends of the main shaft 15 of the rotating arm, and a traveling assembly is installed in each moving arm. Each traveling assembly includes a traveling motor 9, a gear rack 10 connected to the traveling motor 9, and a moving seat arranged corresponding to the guide rail 7. The moving seat is connected to the moving arm, and the moving seat is embedded in the guide rail 7. The moving seat can move along the guide rail 7. The moving arm can reciprocate along the guide rail 7 under the action of the traveling motor 9 and the gear rack 10. Each moving assembly is provided with an unwinding assembly. The guide rail 7 described herein can be a linear guide. A steering roller 4 is respectively arranged on the upper and lower sides of the main shaft 15 of the rotating arm, and the two side ends of the steering roller 4 are respectively connected to the main shaft 15 of the rotating arm through brackets. The arrangement of the moving arms facilitates the adjustment of the distance between the two moving arms in the same moving assembly, thereby achieving the adjustment of the distance between the two corresponding air inflation heads 8, so as to better adapt to paper rolls of different widths. Each moving arm is equipped with a travel motor 9 and a corresponding gear rack 10, etc., which can realize the independent control and movement of the moving arms. In the same moving assembly, only one of the moving arms can be moved as needed; the travel motors 9 in each moving arm can also be controlled at the same time to achieve synchronous movement towards each other (the two moving arms in the same moving assembly are close to each other), away from each other (the two moving arms in the same moving assembly are away from each other), and in the same direction (all the moving arms are in the same direction), so as to facilitate the alignment of the two paper rolls corresponding to the two moving assemblies.

[0030] Each unwinding assembly includes an unwinding motor 5, a synchronous wheel assembly 17 and two rotatable air heads 8. The two air heads 8 are coaxially arranged and used to connect the paper roll 2. However, the two air heads 8 are arranged on two moving arms in the same moving assembly. The synchronous wheel assembly 17 and the unwinding motor 5 are arranged on the same moving arm with one of the air heads 8, and the unwinding motor 5 drives the air head 8 to rotate through the synchronous wheel assembly 17. The synchronous wheel assembly 17 involved here includes a synchronous wheel and a synchronous belt, which can be directly implemented by the existing technology. It mainly plays the role of transmitting the power of the unwinding motor 5 to the air head 8 to achieve the purpose of driving the air head 8 to rotate, so it is not repeated here. The air head 8 is used here to replace the traditional air shaft, so that the paper roll 2 is more convenient. The unwinding motor 5 is set in both unwinding assemblies, and the air head 8 is driven to rotate by the synchronous wheel assembly 17. Such an arrangement facilitates the tension of the unwinding and rolling paper belts to be more stable. The air head 8 described here can be an existing air-expanding winding chuck, etc.

[0031] In some specific implementation manners, each moving component includes two guide rails 7, which are respectively arranged on both sides of the rack and pinion 10. At least one moving seat is provided on each guide rail 7. Such a setting is beneficial to the more stable movement of the moving arm.

[0032] In some specific implementation manners, the two turning rollers 4 are symmetrically distributed with respect to the swivel arm main shaft 15.

[0033] In some specific implementation manners, a diameter sensor 6 is respectively connected to the upper and lower end faces of the swivel arm main shaft 15. The two diameter sensors 6 are arranged in one-to-one correspondence with the two unwinding assemblies. The setting of the diameter sensor 6 is beneficial to the accurate calculation of the diameter on the subsequent corresponding unwinding assembly.

[0034] In some specific implementation manners, a paper surface sensor 13 is connected to the frame 1 through an auxiliary bracket, and the paper surface sensor 13 is arranged corresponding to one of the unwinding assemblies.

[0035] In some specific implementation manners, a button handle bracket 3 is further provided on the frame 1. A button handle 14 for controlling the working state of the movable arm rotary unwinder is arranged through the button handle bracket 3. Both the button handle bracket 3 and the button handle 14 are arranged to avoid the paper surface sensor 13. Of course, when there is a need, two paper surface sensors 13 can also be respectively arranged on the frame 1 corresponding to the two unwinding assemblies.

[0036] In some specific implementation manners, a lifting mechanism can be added to the side of the frame 1 corresponding to the unwinding assembly. The lifting mechanism can directly adopt an existing device to directly implement it, as long as it can place the paper roll and drive the paper roll to rise and fall.

[0037] The working principle of the above-mentioned movable arm rotary unwinder can be as follows:

[0038] 1. Loading the paper roll

[0039] Control the two moving arms in the required moving component to move away from each other, so that the distance between the two moving arms is expanded to be greater than the width of the paper roll 1;

[0040] Through the lifting mechanism or manually, etc., lift the paper roll to the position where the air shaft is located, so that the center line of the paper roll is on the same straight line as the central axis of the air shaft (that is, the state of coaxial setting of the paper roll and the air shaft is achieved);

[0041] Then control the corresponding two moving arms to move towards each other, so that the air shaft is inserted into the core of the paper roll and inflated and tightened.

[0042] If the end faces of the paper rolls on this moving component and the paper rolls on another moving component are not flush, then the two moving arms in one of the moving components can be controlled to move in the same direction for adjustment.

[0043] 2. Unwinding Line Speed Calculation and Control

[0044] The diameter of the paper roll is measured in real time through a roll diameter sensor;

[0045] According to the speed of the production line, the required rotational speed of the paper roll can be calculated through the existing technology, so that the speed of the paper roll is consistent with the speed of the production line.

[0046] The required rotational speed of the paper roll can be adjusted through the unwinding motor (the unwinding motor drives the air shaft and the paper roll connected to the air shaft to rotate). The adjustment of the unwinding motor can be achieved by directly adopting the existing technology (such as: frequency converter, etc.), so it will not be elaborated here.

[0047] 3. Station Flipping

[0048] The alternation of the two stations (mobile components) can be realized by driving the rotating arm main shaft 15 to rotate through the rotating arm speed reducer 16.

[0049] All the above undisclosed matters can be realized by the existing technology, so they will not be elaborated here.

[0050] Finally, it should be noted that: in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0051] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
