Description

Technical Field

[0001] The utility model relates to the technical field of candy packaging and processing, in particular to an easy-tearing opening mechanism for the sugar paper of a packaging machine. Background Art

[0002] In the application of conventional kink-type packaging, there is no glue on the inner side of the sugar paper. After the sugar paper is conveyed in place, the two sides of the sugar paper are directly bundled together, and then the sugar paper at both ends of the candy is kinked. At present, no easy-tearing opening is provided in the conventional kink-type packaging method. When unpacking the candy, only the kinks at one end or both ends can be unknotted, and the operation is complex. Since the candy wrapping paper is generally made of paper or plastic, and the material is relatively hard, there will be many folds after being used to wrap the candy. Therefore, the feel is not good when opening the kink, which will more or less affect the customer's experience satisfaction. Content of the Utility Model

[0026] A sugar paper tear notch opening mechanism of a packaging machine, the sugar paper tear notch opening mechanism is arranged above the sugar paper conveying mechanism, as Figure 1 、 Figure 2 shown, including a connecting rod assembly and a linear sliding assembly. The lower part of the linear sliding assembly is fixedly provided with a mounting plate 9, and a cutting knife 10 is arranged on the mounting plate 9. The cutting knife 10 is parallel to the sugar paper conveying direction. The connecting rod assembly drives the linear sliding assembly to perform a reciprocating linear motion up and down under the action of power, driving the cutting knife 10 to perform a reciprocating motion up and down to complete the opening of the sugar paper tear notch.

[0027] Further, the cutter 10 is as Figure 3 shown, including a tool holder 101 and a blade 102. The tool holder 101 is located on both sides of the blade 102. An elastic protective pad 103 is fixedly provided at the tip portion of the blade 102 corresponding to the tool holder 101. When the cutter 10 moves downward, the protective pad 103 presses the candy wrapper. The protective pad has a certain elasticity. The protective pad compresses to expose the blade inside and cuts a small opening in the candy wrapper, achieving the purpose of easily tearing the candy wrapper. Preferably, the material of the protective pad 103 is foam; the protective pad 103 protrudes from the tip of the blade 102 to protect the blade tip during the non-working state to avoid accidentally injuring maintenance personnel.

[0028] Further, a strip-shaped notch is transversely formed on the mounting plate 9. The cutter 10 slides in the strip-shaped notch and is locked and fixed by a fastening screw. The position of the cutter 10 on the mounting plate 9 can be adjusted according to the requirements of the opening position of the easy tear opening of the candy wrapper. Further, a strip-shaped avoidance groove is formed on the bottom plate 11 of the candy wrapper conveying mechanism corresponding to the position of the blade to prevent the blade from directly contacting the bottom plate 11 when cutting the candy wrapper.

[0029] The link assembly includes link A1, link B2, L-shaped link 3, link C8, and connecting block 5. One end of link A1 is fixedly connected to the driven shaft and the other end is hinged to link B2. The other end of link B2 is hinged to one end of L-shaped link 3. The middle of L-shaped link 3 is rotationally connected to the box body, and the other end is hinged to link C8. The other end of link C8 is hinged to one end of connecting block 5; the other end of connecting block 5 is fixedly connected to the slider 6 of the linear sliding assembly. The driven shaft is driven by the power shaft on the packaging machine, and the power shaft and the driven shaft are connected by a cam link mechanism. The power shaft makes a circular motion to drive the driven shaft to make a reciprocating swing. Link A1 follows the reciprocating swing motion of the driven shaft, drives L-shaped link 3 to reciprocate through link B2, and L-shaped link 3 drives connecting block 5 and the slider 6 of the linear sliding assembly to make a vertical linear motion through link C8.

[0030] The linear sliding assembly includes a base 7, a slider 6, and an adapter plate 4. The base 7 is fixed to the side wall of the box body. A slide rail is vertically provided on the base 7. The adapter plate 4 is fixedly connected to the slider 6. The slider 6 is slidably connected to the slide rail, and the mounting plate 9 is fixedly connected to the adapter plate 4. Preferably, the connecting block 5 is L-shaped. One end of the connecting block 5 is hinged to link C8, and the other end is fixedly clamped between the adapter plate 4 and the slider 6. The slider 6 makes a vertical linear motion along the slide rail driven by the link assembly, drives the adapter plate 4 and the mounting plate 9 to make a vertical linear motion, and thus drives the cutter to move up and down to complete the opening of the easy tear opening of the candy wrapper.

[0031] As Figure 4As shown, under the action of the sugar paper conveying mechanism, the sugar paper moves from right to left. The sugar paper splitting mechanism cuts the sugar paper into a predetermined specification, and then the sugar paper easy-tearing opening mechanism opens the middle part of one side of the sugar paper. When packaging candies, the two ends of the sugar paper in the length direction are knotted, and the opening in the middle is used as an easy-tearing opening, which can facilitate directly tearing the sugar paper.
