[0034] Reference Figure 1-Figure 7 On the one hand, the present application provides a shaft supporting device, including a shaft transporting mechanism 1, a shaft supporting mechanism 2 and a sleeve mechanism 3 arranged on one side of the winder. The shaft transporting mechanism 1 transports the winding shaft to the corresponding side of the winder, and then the shaft supporting mechanism 2 is started to lift the winding shaft to facilitate the sleeve mechanism 3 to sleeve the tube onto the winding shaft.

[0035] Reference Figure 2 and Figure 3Specifically, the shaft transport mechanism 1 includes a shaft transport base 11, which is horizontally arranged and located at the discharge end of the winder. The shaft transport base 11 is provided with a shaft transport guide rail 12, which is extended and laid along the length direction of the shaft transport base 11. The shaft transport guide rail 12 is provided with a support assembly 13, and the support assembly 13 includes a shaft transport tray 131 for supporting the winding shaft and a flip structure 132, the flip structure 132 is installed on the shaft transport guide rail 12, and the shaft transport tray 131 is connected to the shaft transport guide rail 12 through the flip structure 132, and the shaft transport tray 131 is "V"-shaped and is slidably connected to the shaft transport guide rail 12, that is, the shaft transport tray 131 can reciprocate along the length of the shaft transport guide rail 12. In order to drive the support component 13, an axis transport rack is provided on the inner side of the axis transport guide rail 12. Correspondingly, a tray driving component 133 is provided on one side of the axis transport tray 131. The tray driving component 133 includes a motor and an axis transport gear connected to the motor. The axis transport gear is meshed with the axis transport rack. Under the drive of the motor, the operation of the axis transport gear can drive the axis transport tray 131 and the flip structure 132 to move. It can be understood that the support component 13 can be driven by other methods such as motor screw, linear module or belt drive.

[0036] The flipping structure 132 includes a plurality of flipping cylinders arranged along the length direction of the shaft transport guide rail 12 and a flipping rod set on the flipping cylinder. The flipping rod is connected to one side of the shaft transport tray 131. Driven by the flipping cylinder, the shaft transport tray 131 can achieve a certain degree of flipping so as to switch between a supporting state and an upper shaft state: in the supporting state, the shaft transport tray 131 flips vertically upward, and the shaft transport tray 131 will limit the winding shaft placed in the shaft transport tray 131; in the upper shaft state, the side of the shaft transport tray 131 away from the flipping rod will flip to a horizontal state, thereby facilitating the placement of the winding shaft on the shaft transport tray 131.

[0037] In order to cooperate with the shaft transport tray 131, the shaft transport mechanism 1 also includes a placement table 14 for placing the winding shaft, one end of the shaft transport guide rail 12 is located on one side of the placement table 14, and the other end of the shaft transport guide rail 12 is located on one side of the winding machine. By setting the placement table 14 to support and place the winding shaft and cooperating with the support assembly 13, a plurality of winding shafts can be placed on the placement table 14. When a new winding shaft needs to be loaded, the shaft transport tray 131 moves to one side of the placement table 14 and flips to the upper shaft state, and the winding shaft is pushed to the shaft transport tray 131 manually or by using a cylinder, and then the shaft transport tray 131 returns to one side of the winding machine to cooperate with the shaft support mechanism 2.

[0038] Reference Figure 4 and Figure 5The shaft support mechanism 2 includes a shaft support arm 21 for supporting the winding shaft on the shaft transport tray 131, a shaft lifting assembly 22 for cooperating with the shaft support arm 21, and a shaft support driving member 23 for driving the shaft support arm 21. In the present embodiment, there are two shaft support arms 21, and the two shaft support arms 21 are rotatably connected to the two ends of the inner side of the winding machine. One end of the shaft support arm 21 has an adapting groove for cooperating with the winding shaft, and the shape of the adapting groove is adapted to the shape of the end of the winding shaft so that the winding shaft can be conveniently supported and limited; the other end of the shaft support arm 21 has a support arm rotating shaft, and the support arm rotating shaft is coaxially provided with a gear; the support shaft driving member 23 includes a rack meshed with the gear and a cylinder for driving the rack to move, and the cylinder is fixedly mounted on the outer wall of the winding machine.

[0039] By providing the shaft supporting arm 21 and the shaft supporting driving member 23, when it is necessary to lift the winding shaft, the shaft supporting driving member 23 drives the shaft supporting arm 21 to be lowered to the lowest end, at which time the shaft supporting arm 21 is misaligned with the shaft transporting mechanism 1, that is, the shaft supporting arm 21 will not interfere with the shaft transporting mechanism 1. Then the shaft transporting mechanism 1 transports the new winding shaft to the bottom of the shaft supporting arm 21, and the shaft supporting driving member 23 drives the shaft supporting arm 21 to rotate. During the rotation process, the shaft supporting arm 21 contacts the two ends of the winding shaft and lifts the winding shaft, and then the shaft lifting assembly 22 takes over the winding shaft from the shaft supporting arm 21.

[0040] The shaft lifting assembly 22 is used to cooperate with the winding shaft lifted by the shaft supporting arm 21, and lift it to cooperate with the sleeve mechanism 3. Specifically, the shaft lifting assembly 22 includes a shaft lifting base 221. In this embodiment, the shaft lifting base 221 is installed on the winding machine. The shaft lifting base 221 is slidably connected with a first supporting wheel 222 for supporting and lifting the winding shaft, a second supporting wheel 223, a first supporting wheel driving member 224 for driving the first supporting wheel 222, and a second supporting wheel driving member 225 for driving the second supporting wheel 223.

[0041] Specifically, the first supporting wheel driving member 224 includes a first horizontal driving member 2241 arranged on the shaft lifting base 221 and a first vertical driving member 2242 arranged on the first horizontal driving member 2241. In the present embodiment, the first horizontal driving member 2241 is a linear guide rail, which faces the winding machine; the first vertical driving member 2242 is a cylinder, which is vertically arranged. The first supporting wheel 222 is arranged on the first vertical driving member 2242. The first supporting wheel 222 has a first supporting groove for cooperating with the winding shaft, and the shape of the first supporting groove is adapted to the shape of the end of the winding shaft. The second supporting wheel driving member 225 includes a second vertical driving member 2252 arranged on the first horizontal driving member 2241 and a second horizontal driving member 2251 arranged on the second vertical driving member 2252. The second horizontal driving member 2251 and the second vertical driving member 2252 are both cylinders. The second supporting wheel 223 is arranged on the second horizontal driving member 2251. The second supporting wheel 223 has a second supporting groove for cooperating with the winding shaft; the shape of the second supporting groove is adapted to the shape of the end of the winding shaft.

[0042] The second supporting wheel 223 is located on the side of the first supporting wheel 222 away from the sleeve mechanism 3. When the supporting shaft arm 21 lifts the winding shaft, the first vertical driving member drives the first supporting wheel 222 to descend, and the first horizontal driving member 2241 drives the first supporting wheel 222 to move forward to the bottom of the winding shaft. The first vertical driving member drives the first supporting wheel 222 to rise and lift the winding shaft to be flush with the sleeve mechanism 3. With the cooperation of the second supporting wheel 223, the sleeve mechanism 3 inserts the tube into the winding shaft. It can be understood that the supporting shaft mechanism 2 can be installed in the winding machine, or it can be an independent mechanism arranged on one side of the winding machine.

[0043] Reference Figure 6 and Figure 7 The sleeve mechanism 3 is used for sleeve tubes. The sleeve mechanism 3 includes a sleeve base 31. The sleeve base 31 is provided with a sleeve guide rail group 32. The sleeve guide rail group 32 includes a first sleeve guide rail 321 and a second sleeve guide rail 322. The first sleeve guide rail 321 and the second sleeve guide rail 322 are parallel to each other. The first sleeve guide rail 321 and the second sleeve guide rail 322 can be belt drive, chain drive, or linear module. The first sleeve guide rail 321 is provided with a tube transport mechanism 4 for transporting tubes on the side away from the second sleeve guide rail 322. The tube transport mechanism 4 includes a machine base and a tube outlet inclined plate 41 provided on the machine base. The tube outlet inclined plate 41 faces the first sleeve guide rail 321. The tube is led out from the tube outlet inclined plate 41 to the first sleeve guide rail 321. A baffle is provided at one end of the first sleeve guide rail 321 close to the tube outlet inclined plate 41 . After the tube is led out, it will be blocked by the baffle and then transported along the first sleeve guide rail 321 .

[0044] The second sleeve guide 322 is provided with a sleeve tray 33. When the tube of the first sleeve guide 321 is in place, the tube on the first sleeve guide 321 is transferred to the sleeve tray 33 of the second sleeve guide 322. The sleeve tray 33 is in a "V" shape and parallel to the winding shaft to facilitate the subsequent insertion of the tube. In order to drive the sleeve tray 33 to move, a rack is provided on one side of the second sleeve guide 322. Correspondingly, the sleeve base 31 is provided with a sleeve driving member 34 that cooperates with the rack. In this embodiment, the sleeve driving member 34 includes a motor. The output shaft of the motor is coaxially provided with a gear meshing with the rack. When the motor is started, the gear drives the rack to move, thereby driving the second sleeve guide 322 to drive the sleeve tray 33 to continuously move toward the direction of the winding shaft.

[0045] When the tube needs to be sleeved, the first supporting wheel 222 first receives and supports the reel from the supporting arm 21, and then the second supporting wheel 223 lifts the reel, and the reel is separated from the first supporting wheel 222 to make way. At this time, the tube is driven by the sleeve mechanism 3 to continuously move toward the reel, and the tube will not be blocked by the first supporting wheel 222 when it is sleeved into the reel. When one end of the tube begins to be sleeved into the reel, the second supporting wheel 223 is separated from the reel so that the reel returns to the first supporting wheel 222. Since the tube has been sleeved into the reel at this time, it only needs to continue to be sleeved to complete the installation of the tube. The whole process does not require manual sleeve installation, ensuring efficiency while ensuring safety.

[0046] On the other hand, the present application also provides a winding machine, comprising a shaft supporting device as described in any of the above items, wherein the shaft supporting device is arranged on one side of the winding machine.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
