[0030] Reference Figure 1 to Figure 7A snap-fit ​​device comprises a snap-fit ​​frame 013, a fixing plate 7, a clamp fixing assembly, a first plug mounting shaft 9, an expansion assembly 10 and a push assembly 011; the fixing plate 7 is fixed on the snap-fit ​​frame 013, and the fixing plate 7 is arranged vertically; the clamp fixing assembly is used to fix the supporting clamp 63, and the clamp fixing assembly is fixed on the right side of the fixing plate 7; the first plug mounting shaft 9 is arranged on the snap-fit ​​frame 013, and the first plug mounting shaft 9 can slide left and right relative to the snap-fit ​​frame 013, and the first plug mounting shaft 9 extends in the left and right direction The first plug mounting shaft 9 is used for inserting and placing the plug; the expansion component 10 is arranged on the first plug mounting shaft 9, and the expansion component 10 is used to position the through hole 61 on the supporting clamp, and the expansion component 10 is used to position the core of the film roll 62, so that the through hole on the clamp is concentric with the core of the film roll; the pushing component 011 is arranged on the snap-fit ​​frame 013, and the pushing component 011 is driven and connected to the first plug mounting shaft 9, and the pushing component 011 drives the first plug mounting shaft 9 to reciprocate along the left and right directions.

[0031] From the above, it can be concluded that when in use, the user can first place the plug 64 on the first plug mounting shaft 9, so that the first plug mounting shaft 9 passes through the through hole on the supporting splint, and the through hole is tensioned by the expansion of the expansion component 10, so as to realize the positioning of the through hole, and the first mounting plug is driven to move in the left and right directions by the pushing component 011, and the relative position of the splint fixing component and the first mounting plug is adjusted, so that the supporting splint is fixed by the splint fixing component. After fixing the supporting splint, the expansion component 10 loosens the through hole, and the user can move the film roll to the left relative to the first plug mounting shaft 9, so that the first plug mounting shaft 9 is inserted into the roll core, and then the expansion component 10 expands again to realize the positioning of the roll core of the film roll, and fine-tune the film roll to realize centering, ensure that the through hole on the supporting splint and the center of the roll core are concentric, so that the plug on the first plug mounting shaft 9 can be smoothly inserted into the through hole and the roll core to achieve buckling.

[0032] In some embodiments, the clamp fixing assembly includes a plurality of suction cups 8 disposed on the right side of the fixing plate 7, and the suction cups 8 are used to absorb and support the clamp. The structure is simple and convenient to set up. When in use, the support clamp is absorbed and fixed by the suction cups 8.

[0033] Preferably, a plurality of suction cups 8 are provided, and all suction cups 8 are distributed in a circular array with the axis of the first plug installation shaft 9 as the center.

[0034] In some embodiments, the fixing plate 7 is provided with an avoidance hole 70 for passing the first plug installation shaft 9. With the arrangement of this structure, the expansion assembly 10 on the first plug installation shaft 9 can be easily tensioned to support the through hole on the clamping plate to achieve positioning and centering.

[0035] In some embodiments, a cavity is provided in the first plug installation shaft 9, the expansion assembly 10 is arranged in the cavity, a plurality of openings 90 are provided on the side of the first plug installation shaft 9, the openings 90 extend along the radial direction of the first plug installation shaft 9, the openings 90 are connected to the cavity, and the expansion assembly 10 extends out from the openings 90. The structure is simple and convenient to set up. The expansion assembly 10 is arranged in the cavity, and its structure is compact, which can reduce the weight of the plug installation shaft. In addition, the expansion assembly 10 can extend from the opening 90, which can facilitate the expansion and centering positioning of the winding core and the through hole.

[0036] In some embodiments, the expansion assembly 10 includes a pusher 101 fixedly connected to the first plug mounting shaft 9, a push shaft 103 disposed in the cavity, and a plurality of clamping claw blocks 102 disposed on the push shaft 103. The movable portion of the pusher 101 is fixedly connected to the push shaft 103, the clamping claw block 102 is disposed in the opening 90, the clamping claw block 102 is slidably matched with the opening 90, the opening 90 and the clamping claw block 102 are disposed one by one, and the push shaft 103 is disposed one by one. 03 is provided with a plurality of slots 1031, the depth of the slots 1031 gradually decreases from right to left, the inner wall of the slots 1031 is provided with a raised rib 1032, the extension direction of the raised rib 1032 is arranged along the extension direction of the depth of the slots 1031, the raised rib 1032 and the slots 1031 are respectively matched with the jaw block 102 in a concave and convex manner, the jaw block 102 and the slots 1031 are slidably matched, and the jaw block 102 is slidably matched with the raised rib 1032.

[0037] When the pusher 101 drives the push shaft 103 to move from left to right, the clamping jaw block 102 is pushed out along the depth direction of the opening 90 away from the axial direction of the first plug installation shaft 9 as the depth of the slot 1031 decreases under the limiting action of the raised rib 1032, thereby achieving a tightening action.

[0038] When the pusher 101 drives the push shaft 103 to move from right to left, the clamping block increases along the depth of the slot 1031 under the limit of the raised rib 1032 and retracts into the cavity along the depth direction of the opening 90 toward the axial direction of the first plug mounting shaft 9 to achieve the loosening action.

[0039] In some embodiments, the end surface of the clamp block 102 away from the axis of the first plug installation shaft 9 is provided with an inclined surface, and the height of the inclined surface gradually increases from right to left. Through the setting of this structure, it is convenient to guide during the insertion into the through hole or the winding core.

[0043] Preferably, the opening 90 is disposed between the second plug mounting axis 012 and the flange 91 .

[0044] For some smaller apertures, such as Figure 3 As shown, for example, when a plug of about three inches is buckled, a plug of the corresponding size can be directly inserted on the second installation shaft and buckled and installed in the through hole and winding core that match the size of the plug. Since the plug is small in size, the interference area caused by the deviation is small, and the damage to the film roll caused by forced insertion is small. Moreover, when forced insertion is made into the winding core and through hole, the through hole and winding core can also be aligned under the guidance of the plug itself. Therefore, the expansion component 10 can be omitted. In the case of Figure 2 As shown, an expansion assembly 10 is required for a plug of approximately six inches in size.

[0045] In some embodiments, the buckle frame 013 includes a main frame 0131, a sleeve 0132 fixed on the main frame 0131, the fixing plate 7 is fixedly connected to the sleeve 0132 through a transition frame 0133, and the first plug installation shaft 9 slides in the left and right directions through a bearing to cooperate with the sleeve 0132.

The structure is simple and convenient to set up. Through the setting of the structure, it is convenient to control the left and right sliding distance of the first plug installation shaft 9, so that the user can adjust the relative position of the first plug installation shaft 9 and the clamping plate fixing assembly according to different film roll sizes, so as to facilitate the positioning of the through hole.
