[0026] Example:

[0027] See also Figure 1-4A feeding device for blister forming of a blister packaging box comprises a feeding rack 1, a feeding roller 2 is rotatably connected inside the feeding rack 1, a driving motor 3 is fixedly connected to the feeding rack 1, and the output end of the driving motor 3 movably passes through the feeding rack 1 and is fixedly connected to one end of the feeding roller 2, a fixing rod 4 is fixedly connected inside the feeding rack 1, two positioning frames 5 are slidably connected to the fixing rod 4, a group of rollers 6 are rotatably connected in the two positioning frames 5, a synchronization mechanism and a limiting mechanism are arranged between the two positioning frames 5 and the fixing rod 4, the synchronization mechanism is used to simultaneously control the movement of the two positioning frames 5, and the limiting mechanism is used to fix the two positioning frames 5 after movement.

[0028] In this embodiment, the space between the two positioning frames 5 corresponds to the blister equipment. When the blister packaging box is being blister formed, the raw material coil of the blister packaging box is placed on the discharge roller 2, and one end of the coil passes through the two positioning frames 5 and enters the blister equipment. The two positioning frames 5 adjust the spacing on the fixed rod 4 according to the width of the coil. The synchronization mechanism enables the two positioning frames 5 to move simultaneously during adjustment. The adjusted two positioning frames 5 are fixed by the limiting mechanism. The two fixed positioning frames 5 enable the coil to accurately correspond to the blister equipment when loading. Finally, the driving motor 3 controls the discharge roller 2 to rotate to discharge the coil, so that the coil is loaded into the blister equipment. The two sets of rollers 6 ensure smooth loading of the coil.

[0029] Specifically, the synchronization mechanism includes two sliding blocks 71, two racks 72 and a gear 73. The two sliding blocks 71 are respectively fixedly connected to the bottom ends of the two positioning frames 5, and the two sliding blocks 71 are both slidably connected to the outer surface of the fixed rod 4. The two racks 72 are respectively fixedly connected to the two sliding blocks 71 and are distributed in a staggered manner. The gear 73 is rotatably connected to the bottom end of the fixed rod 4, and the two racks 72 are both meshed with the gear 73.

[0030] In this embodiment, when the coil is fed, it passes between the two positioning frames 5. The two positioning frames 5 slide on the fixed rod 4 through the two sliding blocks 71. Through the engagement of the two racks 72 and the gear 73, the two positioning frames 5 move the same distance in the direction of approaching each other. After the movement, the two positioning frames 5 center the coil, so that the coil can be stably aligned with the blister equipment when fed, preventing deviation from affecting the blister forming process of the packaging box.

[0031] Specifically, the limiting mechanism includes a limiting strip 81 and a limiting snap-in 82 . The limiting strip 81 is rotatably connected to a positioning frame 5 , and the limiting snap-in 82 is bored on the fixing rod 4 and corresponds to the limiting strip 81 .

[0032] In this embodiment, after the two positioning frames 5 are moved and adjusted, the limit bar 81 is rotated to make them snap into the limit slot 82. The limit slot 82 restricts the limit bar 81, so that one positioning frame 5 cannot move. The other positioning frame 5 is also unable to move through the setting of the synchronization mechanism. The two positioning frames 5 are restricted at the same time. After the restriction, the two positioning frames 5 are stably positioned in the center of the coil.

[0033] Specifically, a conveying roller 9 is rotatably connected inside the unloading rack 1 , and the conveying roller 9 corresponds to the unloading roller 2 and the two positioning frames 5 .

[0034] In this embodiment, the coil is fed from the unwinding roller 2 and the two positioning frames 5 by bypassing the conveying roller 9, and the conveying roller 9 is used to ensure the tension of the coil when feeding, and prevent the loosening of the feeding material from affecting the blister processing of the packaging box.

[0035] Specifically, one end of the unloading roller 2 away from the driving motor 3 is fixedly connected to a fixing block 11 , and a stop rod 12 is rotatably connected to the unloading frame 1 , and the stop rod 12 corresponds to the fixing block 11 .

[0036] In this embodiment, after the coil is placed on the unwinding roller 2, the blocking rod 12 rotates to the fixed block 11, and the blocking rod 12 restricts the coil to prevent the coil from falling during unwinding.

[0037] Specifically, a baffle 13 is fixedly connected to one end of the discharge roller 2 close to the driving motor 3 , and anti-slip grooves are engraved on the circumferential surface of the discharge roller 2 .

[0038] In this embodiment, the baffle 13 cooperates with the baffle rod 12 to limit the coil, so that the coil is stably discharged on the unloading roller 2, and the anti-slip pattern increases the friction between the unloading roller 2 and the coil, so that the coil is stably discharged by the unloading roller 2.

[0039] Working principle: When the blister packaging box is being blister formed, the raw material coil of the blister packaging box is placed on the discharge roller 2, and one end of the coil passes through the two positioning frames 5 and enters the blister equipment. The two positioning frames 5 adjust the spacing on the fixed rod 4 through two sliding blocks 71 according to the width of the coil. Through the meshing of the two racks 72 and the gear 73, the two positioning frames 5 move simultaneously during adjustment. After the two positioning frames 5 are adjusted, the limit bar 81 is rotated to make it snap into the limit bayonet 82. The limit bayonet 82 limits the limit bar 81, so that one positioning frame 5 cannot move, and the other positioning frame 5 cannot move through the meshing of the two racks 72 and the gear 73. The two positioning frames 5 are restricted at the same time. The two positioning frames 5 after restriction stably center the coil, so that the coil accurately corresponds to the blister equipment when loading. Finally, the driving motor 3 controls the discharge roller 2 to rotate to discharge the coil, so that the coil is loaded into the blister equipment, and the two sets of rollers 6 keep the coil loading smooth.

[0040] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
