[0002] During the production process, products such as paper and cloth are typically wound onto reels, which are then used to transfer these products between the various processing steps. The reels are attached to the corresponding equipment using reels, meaning the reel is first attached to the reel, which is then attached to the equipment. These equipment typically also have motors to drive the reels. For example, in laminating equipment, there are two unwinding reels at the initial position, which rotate to unwind the product from the reels. At the final position, there is a rewinding reel, which rotates to wind the laminated product back onto the reel. The reels and reels are typically secured together by friction. Currently, the reel surface is typically coated with a flexible, compressible layer. The diameter of the flexible layer is smaller at the ends than in the middle, causing the reel to press against the middle. This type of reel also presents challenges: installing and removing the reel from the reel can be difficult. Utility Model Content

[0033] See also Figure 1 、 Figure 2 and Figure 3 A reel for reel installation includes a shaft body 1, a mounting sleeve 2, a plurality of movable blocks 3 and a plurality of elastic members 4.

[0034] The two ends of the shaft body 1 are stepped and are used to be installed in the installation opening 2b of the corresponding equipment. More specifically, bearings can also be installed at both ends of the shaft body 1, and the outer ring of the bearing is installed in the installation opening 2b of the corresponding equipment.

[0035] See also Figure 2 The outer wall of the middle portion of the shaft body 1 is provided with a plurality of air guide grooves 1a, which are interconnected. More specifically, the air guide grooves 1a may include a plurality of strip grooves 1a1 and an annular groove 1a2. The plurality of strip grooves 1a1 may be arranged in a circular array around the axis of the shaft body 1, and the first ends of the plurality of strip grooves 1a1 may all be connected to the annular groove 1a2.

[0036] See also Figure 3 and Figure 4 The mounting sleeve 2 is annular and fixedly connected to the shaft body 1, perhaps using screws. In other words, the inner diameter of the mounting sleeve 2 matches the outer diameter of the middle portion of the shaft body 1. The axial length of the mounting sleeve 2 is designed to be the same as the middle portion of the shaft body 1, so that the mounting sleeve 2 covers the air guide groove 1a.

[0037] The mounting sleeve 2 is further provided with an air valve 2a connected to the air guide groove 1a. More specifically, the air valve 2a may correspond to the annular groove 1a2.

[0038] See also Figure 3 and Figure 5 The mounting sleeve 2 has multiple groups of mounting openings 2b, each radially corresponding to one air guide groove 1a. If the aforementioned embodiment where the air guide groove 1a comprises multiple strip grooves 1a1 and one annular groove 1a2 is adopted, the multiple groups of mounting openings 2b are also arranged in a circular array around the axis of the shaft body 1, corresponding one-to-one to the multiple strip grooves. The figures illustrate six groups of mounting openings 2b as an example.

[0039] Multiple movable blocks 3 are sequentially slidably connected to all mounting openings 2b along the radial direction of the shaft body 1. In other words, the number of movable blocks 3 is the same as the number of mounting openings 2b, with a one-to-one correspondence between the two. More specifically, the mounting openings 2b may include a larger inner opening 2b1 and a smaller outer opening 2b2, and the movable blocks 3 may include an inner block 3a that matches the inner opening 2b1 and an outer block 3b that matches the outer opening 2b2.

[0040] The plurality of sets of elastic members 4 act on the plurality of movable blocks 3 in sequence. In other words, the number of sets of elastic members 4 is the same as the number of movable blocks 3, and the two correspond one to one.

[0041] The elastic member 4 has the following function on the movable block 3: when the air guide groove 1a is not inflated, the movable block 3 is kept close to the shaft 1 for loading and unloading. More specifically, a set of elastic members 4 can be two compression springs, and the surface connecting the inner block 3a and the outer block 3b can have two blind holes 3c for the compression springs to enter.

[0042] Considering that the mounting sleeve 2 and shaft body 1 are installed by inserting the mounting sleeve 2 into the shaft body 1, a blocking portion may be detachably connected to the inner opening 2b1 of the mounting opening 2b. Before installing the mounting sleeve 2 and shaft body 1, the compression spring is inserted into the blind hole 3c of the movable block 3, the movable block 3 is inserted into the mounting opening 2b, and the blocking portion is installed into the inner opening 2b1. During loading and unloading, the movable block 3 abuts against the blocking portion. Neither the blocking portion nor the movable block 3 protrudes beyond the inner wall of the mounting sleeve 2, and there is no interference during the insertion of the mounting sleeve 2 into the shaft body 1.

[0043] See also Figure 5 In some embodiments, the mounting sleeve 2 is composed of at least two annular modules 2c. Two modules 2c are shown as an example in the accompanying drawings. Accordingly, multiple sets of mounting openings 2b are provided on these modules 2c. The modules 2c do not need to be directly connected to each other. Once these modules 2c are sequentially fixed to the shaft body 1, the mounting sleeve 2 is naturally formed.

[0044] See also Figure 5 In some embodiments, based on the aforementioned embodiment where "the mounting sleeve 2 is composed of at least two sector-shaped modules 2c," the movable block 3 abuts the middle portion of the shaft body 1 during loading and unloading. In other words, the width of the movable block 3 is greater than the width of the strip groove 1a1, and the portions on both sides that extend beyond the strip groove 1a1 are used to abut the middle portion of the shaft body 1.

[0045] Module 2c can move radially along shaft body 1 until it rests against shaft body 1 and is then fixedly connected. Therefore, a suitable compression spring is selected and inserted into blind hole 3c of movable block 3, and movable block 3 is inserted into mounting opening 2b. Under the action of the compression spring, movable block 3 can partially protrude beyond the inner wall of module 2c. While module 2c rests against shaft body 1, it naturally overcomes the compression spring, allowing movable block 3 to enter mounting opening 2b. While module 2c and shaft body 1 are fixedly connected, movable block 3 can naturally remain in a loading and unloading state resting against the middle portion of shaft body 1.

[0046] See also Figure 6 In some embodiments, based on the aforementioned embodiment in which "the mounting sleeve 2 is composed of at least two sector-shaped modules 2c," a sealing strip 5 is provided on the outer wall of the middle portion of the shaft body 1 along the air guide groove 1a. More specifically, an embedding groove is provided on the outer wall of the middle portion of the shaft body 1 along the air guide groove 1a. If the aforementioned embodiment in which "the air guide groove 1a may include a plurality of strip grooves 1a1 and an annular groove 1a2" is adopted, the embedding groove includes a first groove and a second groove, the first groove being provided along a first side of the plurality of strip grooves 1a1 and the annular groove 1a2, and the second groove being provided along a second side of the annular groove 1a2.

[0047] The sealing strip 5 is embedded in the embedding groove and partially protrudes from the embedding groove. When the module 2c is pressed against the shaft body 1, the sealing strip 5 is naturally squeezed. When the module 2c and the shaft body 1 are fixedly connected, the squeezed sealing strip 5 is naturally kept in contact with the groove wall of the embedding groove and the inner wall of the module 2c, thereby improving the airtightness.

[0048] The air guide groove 1a is in an uninflated state, and the inner diameter of the reel is slightly larger than the outer diameter of the mounting sleeve 2, so it can be easily inserted into the reel. Adjust the position of the reel on the reel. Inflate the air guide groove 1a from the valve nozzle 2a, overcome the elastic member 4, and move all the movable blocks 3 away from the shaft body 1 until the movable blocks 3 are pressed against the inner wall of the reel, and the reel is fixed to the reel. Install the reel and the reel together on the corresponding equipment for use. During use, there is a corresponding drive unit to drive the reel to rotate. After the reel is used, the reel and the reel are removed from the corresponding equipment together, and the air is deflated through the valve nozzle 2a. The air guide groove 1a returns to an uninflated state, and the reel and the reel can be easily separated.

[0049] See also Figure 7 and Figure 8 In some embodiments, the shaft body 1 has a cavity 1b and an exhaust hole 1c, and the exhaust hole 1c connects the cavity 1b and the air guide groove 1a. A telescopic part 6 that can be extended and retracted is provided in the cavity 1b. The telescopic part 6 rotates with the shaft body 1. More specifically, the cross-section of the telescopic part 6 may be square. One end of the telescopic part 6 can also pass through the first end of the shaft body 1. More specifically, the telescopic part 6 can be extended in a manner such that one end of the telescopic part 6 is rotatably connected to a screw rod 7, the other end of the screw rod 7 passes through the second end of the shaft body 1 and is fixedly connected to a handwheel, and a screw rod 7 nut of a matching screw rod 7 is also fixedly connected to the shaft body 1. When the telescopic part 6 is in the extended state, it blocks the exhaust hole 1c, and when the telescopic part 6 is in the retracted state, it connects the exhaust hole 1c with the outside world. More specifically, the end of the telescopic part 6 that passes through the shaft body 1 may be provided with a section of an exhaust groove 6a.

[0050] When the telescopic portion 6 is extended, the drive unit connects to the end of the telescopic portion 6 that extends beyond the shaft 1, driving the reel to rotate. After the reel is used, the telescopic portion 6 retracts, disconnecting it from the drive unit and simultaneously venting the air guide groove 1a. This allows the air guide groove 1a to return to its deflated state without the need for the valve 2a.

[0051] See also Figure 4 In some embodiments, the surface of the movable block 3 away from the shaft 1 has a soft layer 3d that can be squeezed and deformed. For example, a layer of rubber can be bonded and fixed. Through squeezing and deformation, it fully contacts the inner wall of the reel.
