[0002] Currently, small commodities or small accessories sold on consignment in the market are usually individually packaged, which usually include a packaging bag and a plastic hook attached to the packaging bag. The commodity is wrapped in the packaging bag, such as Figure 1 As shown, one end of the plastic hook 10 is a hook portion 101 for hanging, and the other end has a boss portion 102. The boss portion 102 extends toward the position of the hook portion 101 to have a groove portion 103 that can engage with the boss portion 102. The boss portion 102 and the groove portion 103 are connected together by a plastic strip 104. The packaging bag has a through hole for the boss portion 102 to pass through. When packaging, after the boss portion 102 of the plastic hook is passed through the through hole, the groove portion 103 needs to be manually fastened to the boss portion 102, so that the plastic hook and the packaging bag are fixed. The plastic hook can then be hung on the sales pole for consignment.

[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 3 As shown, an automatic fastening device for a plastic hook includes a machine 1, a placement slot 11 for placing a plastic hook 10 is opened on the machine 1, a first mounting seat 12 is provided at a position corresponding to the placement slot 11 of the machine 1, a first cylinder 2 is provided on the first mounting seat 12, and a piston end of the first cylinder 2 is provided with a pressure plate 21 for pressing the plastic hook 10 in the placement slot 11. Specifically, the first cylinder 2 is arranged vertically, the first cylinder 2 is located above the placement slot 11, and the piston end of the first cylinder 2 is arranged toward the position of the placement slot 11. Preferably, in the present utility model, the placement slot 11 Corresponding to the shape of the plastic hook 10, after the plastic hook 10 is located in the placement groove 11, the top surface of the plastic hook 10 is flush with the top surface of the machine 1, and the pressing plate 21 is located above the placement groove 11. A through groove 22 corresponding to the shape of the placement groove 11 is opened in the middle of the pressing plate 21. It should be noted that the edge of the through groove 22 is slightly smaller than the outer edge of the plastic hook 10, so that when the bottom surface of the pressing plate 21 contacts the top of the placement groove 11, the edge of the through groove 22 can be pressed against the plastic hook 10 in the placement groove 11, thereby pressing the plastic hook 10.

[0031] One end of the plastic hook 10 is a hook portion 101 for hanging, and the other end has a boss portion 102. The boss portion 102 extends toward the position of the hook portion 101 with a groove portion 103 that can engage with the boss portion 102; a through-hole 13 is provided in the placement groove 11 at a position corresponding to the groove portion 103 of the plastic hook 10, and the through-hole 13 passes through the top surface of the machine 1 from the bottom of the machine 1. A second cylinder 14 is provided at the bottom of the machine 1 for pushing the groove portion 103 to the top of the boss portion 102. Specifically, a fixing plate 15 for fixing the second cylinder 14 is fixed to the bottom of the machine 1. The second cylinder 14 is arranged obliquely, and the piston end of the second cylinder 14 is arranged opposite to the position of the through-hole 13. When the second cylinder 14 is working, the piston end of the second cylinder 14 extends from the bottom of the machine 1 into the through-hole 13 and pushes the groove portion 103 toward the top of the boss portion 102.

[0032] It should be noted that the automatic buckling device of the plastic hook of the present invention is mainly used to automatically buckle the plastic hook 10 available on the market. Figure 1 As shown, a plastic strip 104 is integrally connected between the convex column portion 102 and the groove portion 103 of the plastic hook 10, and a dent 105 is provided in the middle of the plastic strip 104. Furthermore, a stop bar 221 for resisting the dent 105 is provided at a position corresponding to the dent 105 in the through groove 22. When the stop bar 221 is provided, when the piston end of the second cylinder 14 pushes the groove portion 103 toward the top of the convex column portion 102, the dent 105 is resisted by the stop bar 221, so that the groove portion 103 can be better bent to the top of the convex column portion 102.

[0033] The first cylinder 2 is also fixed with a second mounting seat 23, and the second mounting seat 23 is provided with a third cylinder 24 for snapping the groove portion 103 located on the boss portion 102 onto the boss portion 102. Preferably, in the present utility model, the third cylinder 24 is arranged vertically, the third cylinder 24 is located above the boss portion 102, and the piston end of the third cylinder 24 is set toward the boss portion 102. When the second cylinder 14 pushes the groove portion 103 toward the top of the boss portion 102 so that the groove portion 103 is located above the boss portion 102, the third cylinder 24 works, and the piston end of the third cylinder 24 moves downward through the through slot 22 to press the groove portion 103 against the boss portion 102, so that the groove portion 103 and the boss portion 102 snap into each other; the through slot 22 is opened on the pressure plate 21 to facilitate the subsequent work of the second cylinder 14 and the third cylinder 24.

[0034] The working principle of the automatic buckling device of the plastic hook of this utility model:

[0035] The operator places the plastic hook 10 in the placement groove 11 on the machine 1, and then places the through hole of the packaging bag 20 on the convex column 102 of the plastic hook 10. The first cylinder 2 works, and the piston end of the first cylinder 2 moves downward, driving the pressure plate 21 to press the edge of the side of the plastic hook 10 located in the placement groove 11. The second cylinder 14 is activated, and the piston end of the second cylinder 14 extends from the bottom of the machine 1 into the through hole 13 and pushes the groove part 103 to the top of the convex column 102, so that the groove After the part 103 is located above the convex column part 102, the third cylinder 24 works (at this time, the second cylinder 14 is at a certain distance from the piston end of the third cylinder 24 to avoid touching the piston end of the third cylinder 24), the piston end of the third cylinder 24 moves downward to press the groove part 103 against the convex column part 102, so that the groove part 103 and the convex column part 102 are engaged with each other. After engagement, the third cylinder 24 returns to its original position, the second cylinder 14 returns to its original position, and the first cylinder 2 returns to its original position. The operator can then take out the engaged plastic hook 10.

[0036] The automatic fastening device of the plastic hook of the present invention has a simple structure and a high degree of automation. When in use, the operator only needs to insert the convex column part 102 of the plastic hook 10 into the through hole of the packaging bag 20, and then place the plastic hook 10 in the placement groove 11 of the machine 1. The first cylinder 2, the second cylinder 14 and the third cylinder 24 cooperate with each other in sequence to automatically fasten the groove part 103 on the convex column part 102, effectively avoiding finger damage and fatigue caused by frequent manual pressing operations.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
