According to thin film materials of different sizes, air shafts of different lengths need to be used.

[0003] The air shaft is usually located above the rewinder. In a conventional rewinder, one end of the air shaft is quickly lifted from the rewinder by a cylinder or other power components, and then a paper tube is manually loaded. However, after the length of the air shaft increases, the air shaft will shake significantly during the lifting process, and it takes a lot of time to wait for the air shaft to stabilize, which affects the efficiency. At the same time, the significant shaking of the air shaft poses a safety hazard. Summary of the Utility Model

[0006] Further, the downward pressure positioning component includes a sliding rod slidably connected to the positioning and fixing component. The sliding rod has a downward pressure end, and a downward pressure member facing the shaft-lifting component is disposed at the downward pressure end.

[0026] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature.

[0027] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0028] Refer to Figure 1 and Figure 2 , an air shaft lifting and positioning device, including a winding mechanism 1, the winding mechanism 1 includes a machine base 11, a winding assembly 12 disposed on the machine base 11 and a shaft lifting assembly 13, and further includes a positioning mechanism 2 disposed on the machine base 11, a material storage mechanism 3 disposed on one side of the winding mechanism 1 and a feeding mechanism 4. When the air shaft lifting and positioning device operates, the winding mechanism 1 drives the air shaft to lift, and the positioning mechanism 2 restricts the movement of the air shaft so as to reduce the stabilization time of the air shaft. After the air shaft is stabilized, the material storage mechanism 3 and the feeding mechanism 4 convey and install a paper tube onto the air shaft.

[0029] Refer to Figure 1 , Figure 2 and Figure 3, specifically, the machine base 11 is used to support and install the winding assembly 12 and the shaft lifting assembly 13. The winding assembly 12 includes a shaft connection block 121 disposed on the machine base 11 and a drive motor 122 for driving the shaft connection block 121. The shaft connection block 121 is provided with an air shaft member 123. In order to achieve shaft lifting, a shaft lifting sliding groove is formed on the machine base 11. The shaft connection block 121 and the drive motor 122 are inserted into the shaft lifting sliding groove and can move up and down within a certain range in the shaft lifting sliding groove. Correspondingly, the shaft lifting assembly 13 includes a shaft lifting connection seat 131 disposed on the shaft connection block 121 and several shaft lifting cylinders 132 disposed on the machine base 11. In this embodiment, the shaft lifting connection seat 131 is disposed above the shaft connection block 121. Both ends in the length direction of the shaft lifting connection seat 131 respectively have connection ends 1311. There are two shaft lifting cylinders 132, and the two shaft lifting cylinders 132 are respectively located on both sides in the length direction of the shaft lifting connection seat 131. The connection ends 1311 are connected to the piston ends of the shaft lifting cylinders 132. Under the combined drive of the two shaft lifting cylinders 132, the shaft lifting connection seat 131 can drive the entire winding assembly 12 to lift, so that the air shaft member 123 is tilted up. The specific structure and working principle of the winding mechanism 1 are both prior arts and can be obtained by purchase, so no further description will be given.

[0030] Referring to Figure 1 , Figure 2 and Figure 4 , in order to ensure efficiency, the shaft lifting assembly 13 needs to quickly lift the air shaft member 123 for the installation of the paper tube. However, when the length of the air shaft member 123 increases, it will vibrate significantly and take a long time to stabilize. By setting the positioning mechanism 2, the stabilization time of the air shaft member 123 can be reduced. Specifically, the positioning mechanism 2 includes a positioning and fixing component 21 disposed on the machine base 11, a downward pressing and positioning component 22 slidably connected to the positioning and fixing component 21, and a driving component 23 for driving the downward pressing and positioning component 22.

[0031] In this embodiment, the positioning and fixing component 21 includes a fixing block 211 fixedly arranged on the machine base 11 and an assembling block 212 arranged on the fixing block 211. For the convenience of installation and disassembly, the assembling block 212 is threadedly connected to the fixing block 211 to achieve detachable connection. The assembling block 212 is also detachably connected to a sliding connection block 213 by threaded connection. The sliding connection block 213 has a chute for cooperating with the downward pressing and positioning component 22. The downward pressing and positioning component 22 moves up and down along the positioning and fixing component 21 and faces the shaft lifting component 13. The downward pressing and positioning component 22 contacts or disengages from the air shaft. In this embodiment, the downward pressing and positioning component 22 includes a sliding rod 221 slidably connected to the positioning and fixing component 21, and the sliding rod 221 is slidably connected to the chute. The sliding rod 221 has a downward pressing end, and a downward pressing member 222 facing the shaft lifting component 13 is arranged at the downward pressing end. In this embodiment, the downward pressing member 222 is a pressing wheel. The downward pressing member 222 has a downward pressing portion 2221 adapted to the shape of the air shaft. The downward pressing portion 2221 is smooth and arc-shaped so as to protect the air shaft during the downward pressing process and avoid hard contact with the air shaft. It can be understood that a sponge layer or a rubber layer can be added to the downward pressing member 222 to further protect the air shaft. The driving component 23 includes a driving member 231 arranged on the assembling block 212 and a connecting member. The driving member 231 is a cylinder, and the connecting member connects the output end of the driving member 231 and the sliding rod 221. Driven by the driving member 231, the sliding rod 221 drives the downward pressing member 222 to move along a predetermined path so as to limit the lifted air shaft member 123, effectively reducing the required stabilization time of the air shaft.

[0032] Refer to Figure 5 , the material storage mechanism 3 is used for storing materials and sending the materials to the feeding mechanism 4. The material storage mechanism 3 includes a material storage frame 31. The material storage frame 31 is located on one side of the machine base 11. When the air shaft member 123 is lifted, the air shaft member 123 will face the material storage frame 31. The material storage frame 31 has a material storage inlet and a material storage outlet 311. The paper tube will be introduced from the material storage inlet and stored in the material storage frame 31. A plurality of guide blocks 32 are arranged between the material storage inlet and the material storage outlet 311. Driven by a conveyor belt, the guide blocks 32 continuously export the paper tube to the material storage outlet 311. An outlet inclined plate 33 connected to the feeding mechanism 4 is arranged at the material storage outlet 311. After the paper tube is transported to the outlet inclined plate 33, it will move along the outlet inclined plate 33 to the feeding mechanism 4.

[0033] The loading mechanism 4 includes a loading frame 41 and a loading limit component 42 arranged on the loading frame 41. The loading frame 41 is located between the shaft-lifting component 13 and the storage mechanism 3. The loading frame 41 has an inclined loading channel 411. One end of the loading channel 411 is located below the discharge inclined plate 33, and the other end of the loading channel 411 faces the shaft-lifting component 13. When the air-expansion shaft member 123 is lifted, one end of the air-expansion shaft member 123 will face the loading channel 411, and the paper tube sliding down from the loading channel 411 will directly sleeve onto the air-expansion shaft member 123. The loading limit component 42 is used to limit the sliding of the paper tube. The loading limit component 42 includes a limit driving cylinder arranged on the loading frame 41 and a loading limit block arranged on the limit driving cylinder. The loading limit block faces the loading channel 411. Driven by the limit driving cylinder, the loading limit block will approach or move away from the loading channel 411 so as to limit or release the limit on the paper tube.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0035] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
