Description

Technical Field

[0001] This utility model relates to the field of carton sealing technology, and in particular to a carton top sealing device. Background Technology

[0002] A carton top sealing device is a device used to seal and close carton lids. It is now widely used in industries such as home appliances, electronics, food, and logistics. For example, it is used to seal carton packaging for products such as biscuits, beverages, and express delivery, or to ensure the sealing and stability of cartons during express delivery.

[0003] In the production of cardboard boxes, the quality of the top sealing of the cardboard box directly affects the integrity and aesthetics of the product packaging. However, during the current transportation process, due to the variety of cardboard box sizes and specifications, the instability of its own center of gravity, and the vibration of the conveying device, the cardboard box is very prone to displacement. This not only leads to deviations in the sealing position and affects the sealing effect, but may also cause equipment failure and reduce production efficiency. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Example: A cardboard box top sealing device, such as Figure 1-2As shown, the system includes: an operating table 1, a transmission device 101, a support block 2, a sliding block 3, a sliding rod 4, a positioning block 5, a sealing machine 6, a spring 7, a double-headed motor 8, a screw 9, a slider 10, a limiting rod 11, and a pressure plate 12. The operating table 1 is fixedly connected to the transmission device 101. The support blocks 2 are fixedly connected to both sides of the top surface of the operating table 1. Each support block 2 has a sliding groove. The support blocks 2 are slidably connected to the sliding blocks 3 through the sliding grooves. The sliding blocks 3 have through holes at both ends of the upper part. The sliding blocks 3 are slidably connected to the sliding rod 4 through the through holes. The sliding rod 4 is fixedly connected to the positioning block 5. The positioning block 5 is fixedly connected to the sealing machine 6 for sealing the carton. The sliding block 3 and the positioning block 5 are connected to each other. The spring 7 is provided, with its two ends fixedly connected to the sliding block 3 and the positioning block 5, respectively. The double-headed motor 8 is fixedly connected to the front and rear ends of the bottom of the positioning block 5, respectively. One end of the screw 9 is rotatably connected to the positioning block 5, and the other end of the screw 9 is fixedly connected to the output shaft of the double-headed motor 8. There are four screws 9. The positioning block 5 has a sliding groove, and the slider 10 is slidably connected to the positioning block 5 through the sliding groove. The slider 10 is threadedly engaged with the screw 9. The slider 10 is symmetrically arranged at the four corners of the bottom surface of the positioning block 5. The slider 10 is fixedly connected to the limiting rod 11 for straightening the carton. The pressure plate 12 for flattening the carton lid is fixedly connected to the front side of the positioning block 5.

[0020] like Figure 1 and Figure 3 As shown, it also includes a drive block 13 and a cylinder 14. The drive block 13 is fixedly connected to the outside of the sliding block 3, and the cylinder 14 is fixedly connected to the operating table 1. The telescopic rod of the cylinder 14 is fixedly connected to the drive block 13.

[0021] like Figure 1 As shown, it also includes a support frame 15 and a roller 16. The support frame 15 is fixedly connected to the bottom surface of the rear end of the sliding block 3, and the roller 16 for compacting the tape is rotatably connected to the support frame 15.

[0022] like Figure 1 As shown, it also includes a limiting strip 17. The limiting strip 17 is fixedly connected to both the left and right sides of the transmission device 101 to prevent the carton from falling off. The limiting strip 17 serves to prevent the carton from falling off the operating table 1.

[0023] like Figure 1 As shown, it also includes a protective plate 18, and the top surface of the conveying device 101 is fixedly connected to the protective plate 18 for preventing the carton from getting stuck; the protective plate 18 serves to prevent smaller cartons from getting stuck in the gap.

[0024] It also includes a lighting lamp 19, which is fixedly connected to the operating table 1 for easy observation later; the lighting lamp 19 serves to facilitate observation of the sealing area.

[0025] When sealing a carton, after starting the equipment, place the carton on the conveying device 101, aligning the position of the carton to be sealed with the direction of the sealing machine 6. The conveying device 101 will then transport the carton to the sealing machine 6. At this time, the carton may be tilted. When the carton contacts the limiting rod 11, since the limiting rod 11 is fixed, the tilted carton will be straightened by the limiting rod 11. If the carton is too small to contact the limiting rod 11, the dual-head motor 8 can be started. The dual-head motor 8 drives the screws 9 on both sides to rotate. The screws 9 drive the slider 10 that cooperates with them to move inward, thereby driving the connected limiting rod 11 to retract inward. In this way, the distance between the left and right limiting rods 11 will be reduced to be able to contact smaller cartons. For larger cartons, the dual-head motor 8 is controlled to reverse, and the screws 9 also reverse, driving the slider 10 and the connected... The limiting rod 11 moves outward until the gap between the two limiting rods 11 is large enough to accommodate the carton. After the carton continues to move, it will contact the pressure plate 12. The pressure plate 12 will press down the raised carton lid to facilitate subsequent sealing. If the overall position of the carton is offset, when it contacts the limiting rod 11, the limiting rod 11 will drive the positioning block 5 and the sealing machine 6 connected to it to shift to the left or right. Since the sliding rod 4 and the sliding block 3 are slidably connected, there will be no jamming during the offset process, aligning the position of the sealing machine 6 with the position where the carton will be sealed. At this time, the spring 7 on one side is compressed and the spring 7 on the other side is stretched. After the carton is sealed, the limiting rod 11 disengages from the carton, and the spring 7 will return to its original position, driving the positioning block 5 and the sliding rod 4 to return to their original positions. This achieves the effect of self-adaptive centering and improves the overall sealing efficiency.

[0026] When sealing shorter cartons, the cylinder 14 needs to be activated. The telescopic rod of the cylinder 14 will move the driving block 13 downwards. At the same time, the sliding block 3 connected to the driving block 13 will also move downwards along the groove in the support block 2, so that the sealing machine 6 lowers its height synchronously and fits against the shorter cartons. Conversely, when sealing taller cartons, the telescopic rod of the cylinder 14 extends outwards, which will push the driving block 13 upwards. At this time, the sliding block 3 rises synchronously, which will raise the sealing machine 6 and fit against the taller cartons. This allows it to adapt to cartons of various sizes and improves the flexibility of the device.

[0027] After the carton is sealed, it continues to be conveyed backward. The carton will then come into contact with the roller 16 at the rear. The roller 16 will press the sealed part of the carton firmly, making the seal tighter. The support frame 15 that fixes the roller 16 is directly connected to the sliding block 3. When the sealing machine 6 rises and falls to adapt to different carton sizes, the sliding block 3 will drive the support frame 15 to change its height, and at the same time drive the roller 16 to move synchronously. This will prevent the carton from being blocked and will effectively press the sealed part firmly, thereby improving the sealing quality.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
