The outer circumferential side of the ferrule 3 is evenly provided with multiple slots 28, and the bottom of the slots 28 is a circular structure, which supports the first steel ball 5 and prevents the steel ball 5 from falling freely downward (center of the circle) (after the pull rod 6 is pulled out). The outer circumferential side of the pull rod 6 is provided with an annular groove 30, and the first steel ball 5 is located in the slots 28 and the annular groove 30, and the ferrule 3 and the pull rod 6 are connected through the first steel ball 5. The width of the annular groove 30 is slightly larger than the contact width of the first steel ball 5 assembled therewith, and the first steel ball 5 is evenly installed in the circumferential slots 28 of the ferrule 3, and is embedded in the annular groove 30 of the pull rod 6, so that the relative axial movement of the pull rod 6 and the ferrule 3 is linked, and the design is simple and stable.

[0037] The connecting frame 4 further comprises a plunger 7, an access hole 27 is provided at the upper right end of the connecting frame 4, and the plunger 7 is connected to the access hole 27. The number of the access hole 27 is one, which is convenient for the first steel ball 5 to enter and exit.

[0038] The right end of the connecting frame 4 is provided with two grooves, which are symmetrically distributed up and down, and a slider 10 is movably connected in each groove. The slider 10 is installed in the two grooves 29 and can slide along the two slots to prevent the reel 18 from axial movement; the structure is simple and stable.

[0039] It also includes a tail spacer 13, a tail bearing cover 14, a pressure ring 19 and a head spacer 21. The tail spacer 13 is sleeved on the outer side of the sleeve 17 and is located between the cylinder seat 12 and the first bearing 16; the left side of the first bearing 16 and the frame 15 are connected through the tail bearing cover 14; the pressure ring 19 is sleeved on the outer side of the sleeve 17 and the right side of the pressure ring 19 is connected to the large gear 20; the head spacer 21 is sleeved on the outer side of the sleeve 17 and is located between the large gear 20 and the second bearing 22.

[0040] It also includes a key 24 and a screw 2. The rotary expansion and contraction oil cylinder 1 and the ferrule 3 are connected by the screw 2. The right inner side of the sleeve 17 is sleeved with the reel 18 by the key 24. The rotary expansion and contraction oil cylinder 1 and the connecting frame 4 are connected by bolts and nuts. The rotary expansion and contraction oil cylinder 1 and the ferrule 3 are connected by the screw 2. The key 24 is used to connect the reel 18 and the sleeve 17. The connections are all detachable, simple in structure, reliable in connection, and easy to assemble and disassemble.

[0041] The upper surface of the second steel ball 9 is higher than the upper surface of the pressing plate 8. The second steel ball 9 is assembled in the slider 10 and fixed by the pressing plate 8, and the second steel ball 9 can rotate in the mounting hole. The upper surface of the second steel ball 9 is higher than the upper surface of the pressing plate 8, so that the upper surface of the pressing plate 8 and the slot 26 of the reel 18 are always not in contact, thereby forming a rolling friction pair between the second steel ball 9 and the slot 26 of the reel 18, so that the operation of the equipment is more stable and reliable, and the service life of the equipment is also extended.

[0042] A displacement sensor is installed at the right end of the rotating expansion and contraction oil cylinder 1 to accurately control the position of the oil rod extension and contraction, thereby improving work efficiency and accuracy.

[0043] Embodiment 3:

[0044] Based on Example 2, a reel quick change method includes the following specific steps:

[0045] When the reel 18 is working, the oil cylinder 11 extends to push the slider 10 into the slot 26 of the reel 18, the large gear 20 drives the sleeve 17 to rotate, and the sleeve 17 drives the reel 18 to rotate through the key 24;

[0046] When the incoming material production specifications change and the reel 18 is disassembled, the oil cylinder 11 retracts and pulls the slider 10 out of the slot 26 at the tail of the reel 18, and the rotating expansion and contraction oil cylinder 1 continues to push to the right until the first steel ball 5 moves to the access hole 27 of the connecting frame 4. At this time, the reel 18 is further pulled out, and the first steel ball 5 is squeezed by the annular groove 30 of the pull rod 6 and withdraws to the access hole 27 of the connecting frame 4, and the reel 18 and the pull rod 6 are completely pulled out;

[0047] When installing the reel 18, the rotating expansion and contraction cylinder 1 pulls the reel 18 to the left through the pull rod 6 until the cylinder 11 extends out of the slider 10 and enters the slot 26 of the reel 18 and the first steel ball 5 enters the annular groove 30 of the pull rod 6, and the installation is completed.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, a plurality of slots are evenly formed on the ferrule 3. The bottom of the slot 28 is a circular structure, which holds the first steel ball 5 and prevents the steel ball 5 from falling freely downward (center of the circle) (after the pull rod 6 is pulled out). When the oil rod of the rotating expansion and contraction oil cylinder 1 is fully retracted, there is a gap between the ferrule 3 and the pull rod 6, and the gap size is a.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, the pull rod 6 is provided with an annular groove, the width of which is slightly larger than the contact width of the first steel ball 5 assembled therewith, and the ferrule 3 together with the first steel ball 5 can move relative to each other along the annular groove on the pull rod 6, and the relative movement distance is b. Dimension b is larger than dimension a.

[0050] from Figure 1 and Figure 4 At the beginning, when the oil rod of the rotating expansion and contraction oil cylinder 1 extends from the zero position (the position where the oil rod is fully retracted), it pushes the ferrule 3 to move forward, and the ferrule 3 pushes the first steel ball 5 to move forward; when the oil rod of the rotating expansion and contraction oil cylinder 1 extends from the zero position (the position where the oil rod is fully retracted) by a distance a, the ferrule 3 pushes the first steel ball 5 to move forward by a distance a, at which time the ferrule 3 has contacted the upper pull rod 6, and since the dimension b is greater than the dimension a, the front end face of the first steel ball 5 has not yet contacted the rear end face of the pull rod 6 slot, and during this process, the outer diameter of the reel 18 does not change at all; when the oil rod of the rotating expansion and contraction oil cylinder 1 continues to extend, the oil rod of the rotating expansion and contraction oil cylinder 1 pushes the ferrule 3, and the ferrule 3 pushes the pull rod 6 to move forward, and the reel 18 begins to shrink in diameter, and the outer diameter of the reel 18 becomes smaller, and when the oil rod of the rotating expansion and contraction oil cylinder 1 continues to extend by a displacement c, the outer diameter of the reel 18 shrinks to the minimum, and at this time the pull rod 6 begins to push up the reel 18, and the outer diameter of the reel 18 cannot continue to shrink.

[0051] It can be seen from the above process that when the oil rod of the rotating expansion and contraction oil cylinder 1 is extended from the zero position (the oil rod is fully retracted position) to the limit position (the process of the reel 18 shrinking in diameter), the first steel ball 5 is always free from force.

[0052] When the oil rod of the rotating expansion and contraction oil cylinder 1 begins to retract, the ferrule 3 is pulled to move backward, and the ferrule 3 pulls the first steel ball 5 to move backward; when the oil rod of the rotating expansion and contraction oil cylinder 1 is retracted to a distance a, the ferrule 3 pulls the first steel ball 5 to move backward, and the pull rod 6 does not move during this process. At this time, the ferrule 3 and the pull rod 6 have a distance a, and the first steel ball 5 in the ferrule 3 begins to contact the groove surface of the pull rod 6. During this process, the outer diameter of the reel 18 does not change; when the oil rod of the rotating expansion and contraction oil cylinder 1 continues to retract, the oil rod of the rotating expansion and contraction oil cylinder 1 pulls the ferrule 3 to move backward, and the ferrule 3 pulls the first steel ball 5 to move backward. The ferrule 3 pushes the pull rod 6 to move backward by squeezing the first steel ball 5. At this time, the outer diameter of the reel 18 begins to change, and the outer diameter of the reel 18 begins to increase.

[0053] like Figure 1 , Figure 2 and Figure 4 As shown, a ring groove is provided on the inner hole of the connecting frame 4, and an access hole is provided at the position of the ring groove, and the plunger 7 is installed on the access hole; the width of the ring groove on the inner hole of the ring groove of the connecting frame 4 is slightly larger than the diameter of the first steel ball 5, which is convenient for assembly and disassembly; and when the first steel ball 5 moves to the ring groove of the connecting frame 4, the first steel ball 5 can completely withdraw from the ring groove on the pull rod 6, so that the pull rod 6 and the first steel ball 5 can be completely separated, as shown in FIG. Figure 5 shown.

[0054] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting frame 4 has two grooves, and the slider 10 is installed in the two grooves and can slide along the two grooves. When the reel 18 needs to be replaced, the cylinder 11 drives the slider 10 to retract, and the reel 18 is pushed out by rotating the expansion and contraction cylinder 1. Figure 5 shown.

[0055] like Figure 1 , Figure 3 and Figure 4 As shown, the second steel ball 9 is assembled in the slider 10 and fixed by the pressure plate 8, and the second steel ball 9 can rotate in the mounting hole. The upper surface of the second steel ball 9 is higher than the upper surface of the pressure plate 8, so that the upper surface of the pressure plate 8 and the card slot at the tail of the reel 18 are always not in contact, thereby forming a rolling friction pair between the second steel ball 9 and the card slot at the tail of the reel 18, so that the operation of the equipment is more stable and reliable, and the service life of the equipment is also extended.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, an annular groove is provided on the reel 18. When the slider 10 slides into the annular groove, the reel 18 can be prevented from axially moving.

[0057] like Figure 1 and Figure 4 As shown, the reel 18 and the sleeve 017 are connected by a key 024.

[0058] A displacement sensor is installed at the tail of the rotating expansion and contraction oil cylinder 1 to accurately control the position of the oil rod extension and contraction.

[0059] When the reel 18 works normally, the oil rod of the oil cylinder 11 extends to push the slider 10 to slide into the slot at the tail end of the reel 18, and the large gear 020 drives the sleeve 017 to rotate; the sleeve 017 drives the reel 18 to rotate through the key 024, and the second steel ball 9 in the slider 10 forms rolling friction with the slot at the tail end of the reel 18 to prevent the reel 18 from axial stringing.

[0060] Figure 1 and Figure 4 The position shown is the state when the reel 18 expands to its maximum diameter.

[0061] When the specifications of incoming materials change and the reel 18 needs to be replaced, the oil rod of the oil cylinder 11 is retracted, the slider 10 is pulled out of the slot at the tail of the reel 18, and the oil rod of the rotating expansion and contraction oil cylinder 1 continues to be pushed forward until the first steel ball 5 moves to the annular groove of the inner hole of the connecting frame 4 (see Figure 5 ), at this time, the unloading trolley (or the loading trolley) can hold the reel 18 and continue to pull the reel outward, and the first steel ball 5 is squeezed by the annular groove of the pull rod 6 and withdraws into the annular groove of the connecting frame 4, and the entire reel 18 together with the pull rod 6 can be completely pulled out. Figure 5 shown.

[0062] The process of loading the reel 18 of the new specification is exactly opposite to the process of pulling out the reel 18 of the old specification, which will not be described in detail here.

[0063] During the entire roll replacement process, the roll replacement can be completed by relying on the equipment's own mechanism and system. The operation process can be automated, the replacement process is fast and efficient, and the equipment runs stably and reliably after assembly.
