Description

Technical Field

[0001] The invention relates to a carton sealing machine, in particular to an integrated I-shaped carton sealing machine. Background Art

[0002] In the packaging industry, the efficiency and space utilization of packaging equipment are of great significance to production efficiency and cost control. Taking a certain type of industrial shell packaging as an example, the traditional packaging process usually relies on two devices to work together to complete the sealing process: the straight sealer is responsible for the initial packaging of the main part of the shell, and the corner sealer is responsible for reinforcing and sealing the corners of the box. The two devices need to run synchronously. The operator not only needs to debug and monitor the equipment parameters separately, but also needs to coordinate the working rhythm between the equipment to ensure the consistency of packaging quality, which undoubtedly increases the complexity of manual operation and management costs.

[0003] In terms of the space occupied by the equipment, the simultaneous operation of two independent devices requires a large installation site, which places high demands on the factory space. In the modern industrial production environment where every inch of land is valuable, this high-space-consuming equipment configuration solution not only limits the flexibility of the company's production line layout, but also increases operating costs such as site rental and equipment maintenance. In addition, the collaborative operation of multiple devices also has problems such as high energy consumption, scattered fault points, and difficult equipment maintenance, which to a certain extent restricts the improvement of packaging efficiency and production benefits.

[0004] With the increasing requirements of industrial production for intelligence and integration, traditional split packaging equipment can no longer meet the high-efficiency, compact and low-cost production needs of modern manufacturing. Therefore, the development of a compact, functionally integrated one-piece I-shaped carton sealing machine to solve the problems of scattered equipment, low space utilization and complex operation in the existing technology has become a technical problem that needs to be solved urgently in the industry.

[0033] When using this device, the staff place the box on the electric conveyor roller 2 on the left side, start the motor of the electric conveyor roller 2, and the motor drives all the conveyor rollers to rotate through the sprocket and chain drive. Then the box is conveyed to the left. The top of the middle side of the box presses against the one-way roller 104 of the middle side sealing component 10 of the mounting frame 5, and the top of the middle side of the box presses against the one-way roller 104 of the middle side sealing component 10 of the frame 1. The one-way rollers 104 on the two first swing rods 103 all swing leftward around the first rotating shaft 102, and the tape adheres to the middle side position of the box. The upper part of the first swing rod 103 swings rightward and drives the second swing rod 107 to swing leftward through the connecting rod 109, and the rotating roller 108 correspondingly lifts upward. The first elastic member 1010 is compressed. The motor of the belt conveyor component 8 starts and drives the box to continue moving leftward through the belt pulley and flat belt. Under the guiding action of the two auxiliary plates 144, the box can be kept from tilting, which is beneficial to the sealing process. The second elastic member 143 enables the auxiliary plates 144 to adapt to boxes of different widths. The box presses against the top block 1014 and swings, and then the swing block 1011 drives the cutting knife 1012 to swing upward. When the box conveys to the position of the left electric conveyor roller 2 and disengages from the top block 1014, the swing block 1011 drives the cutting knife 1012 to reset, and the cutting knife 1012 cuts off the tape. The rotating roller 108 can press the adhered tape firmly against the box. When the box is transmitted to the position of the cross 35, the cylinder 37 extends and drives the mounting plate 33 to move upward. The rotating shaft 34 on the mounting plate 33 and the cross 35 lift the box. The servo motor 36 drives the box to rotate 90°. The servo motor 36 stops moving, and the cylinder 37 resets. Then the cross 35 drives the box to reset. At the same time, control the motor of the electric conveyor roller 2 to rotate in the reverse direction, drive the conveyor roller to rotate in the reverse direction through the chain, and the motor of the belt conveyor component 8 rotates in the reverse direction. At the same time, the staff control the operation of the electric slide rail 92, and then drive the sealing components 10 on the front and rear sides of the mounting frame 5 to move downward, the sealing component 10 in the middle side of the mounting frame 5 to move upward, the sealing components 10 on the front and rear sides of the frame 1 to move upward, and the sealing component 10 in the middle side of the frame 1 to move downward. Then when the box is conveyed to the right, the sealing components 10 on the front and rear sides can package both sides of the box. The L-shaped guide plate 122 of the bonding component 12 contacts the tape on both sides of the box, and realizes the bonding of the suspended side of the tape to the side wall of the box. The pressing wheel 135 further presses the tape adhered to the side wall firmly against the box, completing the I-shaped packaging of the box. The wiping roller 112 of the wiping component 11 can remove the impurities on the box, which is beneficial to the tape packaging. The structure of this device is simple and can realize the I-shaped packaging operation of the box.
