Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging equipment, and more specifically, to an automatic cover folding and sealing machine. Background Art
[0002] A carton sealer is a mechanical device used for packaging, which is specially used to seal cartons. The main function of a carton sealer is to use tape to firmly bond the lid and bottom of the carton together to ensure the safety of the items in the box. A carton sealer can not only be used alone, but also be used in conjunction with other packaging equipment such as carton openers, case packers, labeling machines, etc. to form a complete automated packaging production line. In addition to common automatic carton sealers, there are also special types of carton sealers, such as corner carton sealers, which are suitable for products with higher packaging requirements. Carton sealers are indispensable equipment in the modern packaging industry. They improve packaging efficiency and ensure product safety through automation, and help reduce production costs and protect the environment.
[0003] In the prior art, after the box is sealed, it is necessary to send the sealed box to the labeling line to continue the labeling work, which wastes a lot of working time and is also very difficult to carry, greatly affecting the production efficiency. In addition, in the prior art, the folding of the left and right covers of the carton is only completed by two swing arms. The disadvantage is that if the left and right covers are opened outward, the swing arm will easily poke the cardboard, affecting the appearance of the subsequent carton packaging.
[0004] Therefore, in order to solve the above technical problems, the present application proposes an automatic folding and sealing machine. Utility Model Content

DETAILED DESCRIPTION
[0025] like Figure 1-4As shown, the utility model provides an automatic folding and sealing machine, comprising a workbench 1, a sealing mechanism 5, and a conveying mechanism 2 arranged on the workbench 1, lifting mechanisms 6 are arranged on both sides of the workbench 1, and a mounting bracket 11 is arranged between the lifting mechanisms 6, and a left and right plate folding mechanism 9 for folding the left and right cover plates of the carton is arranged on the mounting bracket 11, and a labeling mechanism 10 is arranged near the sealing mechanism 5.
[0026] The left and right plate folding mechanism 9 includes an electric telescopic rod 92, and a square plate 91 is symmetrically arranged at the bottom of the first mounting plate 96. The electric telescopic rod 92 is installed on the first mounting plate 96 on one side, and the end of the electric telescopic rod 92 is connected to the square plate 91. A plurality of groups of slide rails 95 are arranged at the bottom of the first mounting plate 96. The square plate 91 is slidably connected to the slide rails 95, and a rotating disk 93 is arranged at the center of the first mounting plate 96.
[0027] The labeling mechanism 10 comprises a mounting rod 102 on which the labeling mechanism 10 for attaching labels to cartons is disposed.
[0028] The cylinder 31 is extended and retracted to rotate the part connected to the first mounting block 32, thereby pushing the folding rod 33 to swing inward, thereby folding the rear cover of the carton, and then the front cover contacts the rear cover folding plate 4 to close the front cover, and the first spring 7 on the first connecting column 8 will cushion the impact of the carton to prevent damage to the carton.
[0029] The electric telescopic rod 92 contracts to pull back the square plate 91, and the square plate 91 slides in the slide rail 95. The rotating rod 94 connected to the square plate 91 moves inward, so that the rotating disk 93 rotates, pulling the square plate 91 on the other side to move inward, thereby closing the left and right cover plates of the carton.
[0030] The motor 101 drives the rotating column 103 to rotate, thereby driving the cam 104 on the rotating column 103 to rotate. When the protruding part of the cam 104 contacts the roller 108, it will push it outward, and then the second connecting column 111 moves outward, thereby the second installation moves outward, and then the labeling block 106 sticks the label on the carton.
[0031] Working principle: The staff first adjusts the lifting mechanism 6 to control the entire device at a suitable working height, and then puts the carton on the conveying mechanism 2 on the workbench 1. The cylinder 31 is extended and retracted to rotate the part connected to the first mounting block 32, thereby pushing the folding rod 33 to swing inward, so that the rear cover of the carton is folded, and then the front cover contacts the rear cover folding plate 4 to close the front cover, and the carton is sealed through the sealing mechanism 5. The first spring 7 on the first connecting column 8 will buffer the impact of the carton to prevent the carton from being damaged. The electric telescopic rod 92 contracts to pull back the square plate 91, and the square plate 91 slides in the slide rail 95. The rotating rod 94 connected to the square plate 91 moves inward, so that the rotating disk 93 rotates, pulling The square plate 91 on the other side moves inward, thereby closing the left and right covers of the carton. The motor 101 drives the rotating column 103 to rotate, thereby driving the cam 104 on the rotating column 103 to rotate. When the protruding part of the cam 104 contacts the roller 108, it will be pushed outward, and the second spring 109 is stretched by the tension, and then the second connecting column 111 moves outward, so that the second installation moves outward, and then the labeling block 106 sticks the label on the carton to facilitate subsequent identification. When the protruding part of the cam 104 does not contact the roller 108, the second spring 109 restores its deformation and pulls the labeling block 106 in the second installation block 105 back inward, and then the second connecting column 111 shrinks into the fourth installation block 112.
[0032] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
