Description

Technical Field

[0001] The utility model relates to the technical field of coating and winding mechanisms, and more specifically to a coating and winding shaft. Background Art

[0002] For the coating winding mechanism, there are three conventional winding methods: cantilever type, support locking type, and removing and then putting the entire air shaft back on. However, the cantilever type has two defects that affect the service life of the air shaft. Because the air shaft is hollow and needs to be installed with an airbag and a key strip, the entire cantilever winding pole piece has low load-bearing strength. In addition, the entire air shaft may be deformed due to uneven force during cantilever operation; the locking type conventionally uses a cylinder-driven pin to lock. The cylinder shaft extends to drive the connecting pin to fix the tail end of the air shaft. An air source must be supplied during operation. For example, the utility model patent No. CN220722948U discloses a lithium battery winding guide plate locking and positioning device. The biggest drawback of this method is that the consumption of the air source may cause unnecessary waste during long-term operation. The cylinder has a certain service life and may wear out after long-term work. It cannot be locked tightly after wear and needs regular inspection or replacement, which increases maintenance costs and operational complexity. Utility Model Content

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] Please refer to Figure 1 An embodiment of the present invention provides a coating reel, including a fixed seat 1, a rotating seat 11, a support seat 2, an inflatable shaft 3, a power transmission assembly 4, a tensioning assembly 5, an indexing positioning pin 6, a bearing positioning sleeve handle 7, a raceway support plate 8 and other components. The following is a detailed description of the various components of this embodiment in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the rotating seat 11 can be slidably connected to the fixed seat 1, and the transmission end of the inflatable shaft 3 is rotatably set on the rotating seat 11 through the first rotating bearing 91. The upper end of the support seat 2 is provided with a card slot 21 opening outward and is parallel to the rotating seat 11 in the horizontal direction. The locking end of the inflatable shaft 3 is rotatably set on the bearing seat 22 in the card slot 21 through the second rotating bearing 92.

[0022] Preferably, the tensioning assembly 5 is rotatably arranged on the outside of the fixed seat 1 and is located on the lower side of the rotating seat 11. The outer side of the transmission end of the inflatable shaft 3 is coaxially connected with the first spur gear 31 located on the outside of the fixed seat 1. The power transmission assembly 4 is rotatably arranged on the fixed seat 1 through the support 13 and is fixed to the other side of the rotating seat 11. The power transmission assembly 4 is transmission-connected to the first spur gear 31 and can be transmission-connected to the tensioning assembly 5 through a transmission member.

[0023] like Figure 4 As shown, specifically, the bearing positioning sleeve handle 7 is fixedly connected to the locking end of the inflatable shaft 3 and extends out of the outer end of the slot 21. Two symmetrically arranged waist-shaped positioning grooves 221 are provided on the outer cylindrical surface of the bearing seat 22. There are two indexing positioning pins 6, which pass through the two outer side walls of the slot 21 respectively and are rotatably inserted into their respective corresponding waist-shaped positioning grooves 221. The raceway support plate 8 is fixedly set on the inner side surface of the fixed seat 1 through the mounting plate and is located below the inflatable shaft 3. A third rotating bearing 93 is sleeved on the side of the inflatable shaft 3 close to its transmission end. The outer wall surface of the third rotating bearing 93 is in rolling contact with the top surface of the raceway support plate 8. A limiting screw 81 is vertically provided on the top surface of the opening end of the raceway support plate 8 corresponding to the slot 21.

[0024] During specific implementation, when it is necessary to lock the locking end of the air shaft 3, after inserting the two indexing pins 6 into their respective corresponding waist-shaped positioning grooves 221 and inserting them downward to the lower stop position, the indexing pins 6 are rotated 90° to lock the locking end of the air shaft 3.

[0025] As Figure 3 shown, in this embodiment, the fixed seat 1 may include an upper rotating pin fixing plate 101 and a lower rotating pin fixing plate 102. The structure of the upper rotating pin fixing plate 101 is set as an inverted U shape. The opening of the upper rotating pin fixing plate 101 faces downward and is fixedly connected to one side of the support 13 and the two outer sides of the lower rotating pin fixing plate 102 through locking screws.

[0026] Furthermore, in order to make the sliding of the rotating seat 11 smooth and stable, an upper rotating pin 14 and a lower rotating pin 15 may also be included. Coaxial rotating pin holes are respectively opened at the upper and lower ends of the rotating seat 11. The upper rotating pin 14 and the lower rotating pin 15 are respectively arranged at the bottom of the upper rotating pin fixing plate 101 and the top of the lower rotating pin fixing plate 102 and are respectively in rolling contact with the two rotating pin holes of the rotating seat 11.

[0027] Preferably, the power transmission component 4 may include a second spur gear 41, a synchronous pulley 42 and a fourth rotating bearing 94. The second spur gear 41 is rotatably arranged on the outside of the support 13 through the fourth rotating bearing 94. The synchronous pulley 42 is coaxially arranged with the second spur gear 41 and is fixed on the outer end face of the second spur gear 41. The second spur gear 41 meshes with the first spur gear 31. The synchronous pulley 42 and the second spur gear 41 can be rotated by a rotation driving device to drive the air shaft 3 to rotate.

[0028] During specific implementation, when it is necessary to remove the coating material roll from the air shaft 3, first pull the two indexing pins 6 outward to the upper stop position and rotate them 90°, so that each indexing pin 6 is separated from the waist-shaped positioning groove 221. Hold the bearing positioning sleeve handle 7 at one end of the air shaft 3 and pull it outward in the direction of the opening of the card slot 21. At the same time, the rotating seat 11 moves away from the support 13 on the fixed seat 1, so that the first spur gear 31 is disengaged from the second spur gear 41. Then, the third rotating bearing 93 rolls a certain distance on the raceway support plate 8 in the direction of the limit screw 81 and is limited by the limit screw 81. Finally, the air shaft 3 is deflated and the coating material roll is removed.

[0029] Preferably, the first rotating bearing 91, the second rotating bearing 92, the third rotating bearing 93 and the fourth rotating bearing 94 are all preferably set as deep groove ball bearings.

[0030] Furthermore, the tensioning assembly 5 may include a tensioning wheel shaft 51 and a tensioning pulley 52. The tensioning wheel shaft 51 is fixedly arranged on the outside of the fixed seat 1 and is located on the lower side of the inflatable shaft 3. The tensioning pulley 52 is rotatably sleeved on the outer end of the tensioning wheel shaft 51 and is arranged parallel to the synchronous wheel 42.

[0031] The transmission member may be configured as a tensioning belt that can be sleeved on the tensioning pulley 52 and the synchronous pulley 42 .

[0032] In practice, an external rotary drive device can be connected to the synchronous wheel 42 of the power transmission assembly 4 to drive the synchronous wheel 42 and the second spur gear 41 to rotate, thereby driving the first spur gear 31 meshing with the second spur gear 41 and the inflatable shaft 3 to rotate. In addition, the tensioning pulley 52 applies appropriate tension to the tensioning belt, helping to prevent the tensioning belt from slipping. The tension level can be easily adjusted to ensure effective power transmission.

[0033] Preferably, in order to provide a more stable support connection for the support 13 , a connecting plate 16 may be further included, and the bottom of the support 13 is fixedly connected to the inner side surface of the fixing base 1 through the connecting plate 16 .

[0034] To sum up, the utility model adopts a design of unlocking and locking the locking end of the inflatable shaft by adopting an indexing positioning pin and driving the transmission end of the inflatable shaft to slide in translation through a rotating seat. The locking end of the inflatable shaft can be quickly unlocked and locked by simply pulling up or inserting and rotating the indexing positioning pin. The operation is simple and convenient, which reduces the complexity of the operation, greatly reduces the manual burden, improves the roll changing efficiency, and ensures the continuity of production.

[0035] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
