Description

Technical Field

[0001] This utility model relates to the field of box sealing technology, and in particular to an adaptive size box sealing machine for sealing foam boxes. Background Technology

[0002] With the continuous development of the logistics industry, the use of packaging boxes is constantly increasing. Especially for the logistics packaging of glass products, the fragility of glass presents new challenges to packaging processes and mechanization. Highly automated, mechanized, and efficient packaging machinery is beginning to attract attention across various industries. Traditional packaging requires manual operation, resulting in low efficiency and high costs. While carton sealing machines on the market are already highly efficient, they suffer from problems such as excessive size, high price, and inability to fully adapt to box sizes. Although some carton sealing machine production lines can adapt to different box sizes, they still require additional vacuum pumps, making them suitable only for large-scale factory production lines and not for small businesses such as e-commerce and express delivery shops.

[0003] There are some products on the market that use stepper motors to achieve adaptive contouring of foam box height. However, due to unreasonable structures, there are issues with the sequence of actions when cooperating with width adaptive mechanisms.

The length of the push plate 61 in the design is slightly shorter than the length of the front roller platform 81, which can push the foam box located on the front roller platform 81 and adjust the left and right positions of the foam box.

[0059] Two infrared distance meters 7 are also provided, and the two infrared distance meters 7 are fixed on the two sides of the front roller platform 81 and located at the front side of the push plate guiding mechanism 6. The infrared distance meters 7 cooperate with the push plate guiding mechanism 6 to adjust the left and right positions of the foam box.

[0060] Working principle:

[0061] First, lock the casters to prevent the machine from moving. After adjustment, turn on the power supply of the device, and the sealing machine starts to operate. The transportation motor 811 starts to drive the chain wheel to rotate, and the chain transmits power to each front roller 812, which drives the foam box on the front roller platform 81 to move forward.

[0062] When the foam box passes through, the infrared distance meter 7 fixed on the front roller platform 81 measures the height position of the box, and transmits the electrical signal to the height adjustment motor 44 and the vertical lead screw motor 54 through PLC control, thereby adjusting the height of the upper and lower sealing mechanisms 2 and the two side sealing mechanisms 23 to adapt to the size of the foam box.

[0063] At the same time, the infrared distance meters 7 fixed on the two sides of the front roller platform 81 measure the distance between the box and the two sides of the front roller platform 81, and transmit the electrical signal of the PLC to the push rod motor 62 and the width adjustment motor 56 through data comparison. The push rod motor 62 pushes the foam box through the push plate 61 to adjust the left and right positions of the foam box, so that the foam box always moves in the middle position of the front roller platform 81.

[0064] While the foam box moves on the front roller platform 81, the width adjustment motor 56 drives the second vertical lead screw 53 to rotate to adjust the horizontal distance between the two side sealing mechanisms 23 to adapt to the width of the foam box.

[0065] When the foam box enters the sealing mechanism 2 of the machine, i.e. enters the rack 1, the front sealing wheels 209 of the upper and lower sealing mechanisms 2 and the two side sealing mechanisms 23 are supported by the foam box and are lifted towards the inside of the sealing mechanism 2. Under the action of the connecting rod 205, the rear sealing wheels 210 of the upper and lower sealing mechanisms 2 and the two side sealing mechanisms 23 naturally lift up along with the front sealing wheels 209.

[0066] At this time, the friction force between the adhesive tape passing through the front sealing wheel 209 and the surface of the box causes the adhesive tape to be pasted at the opening of the foam box and on both sides. As the foam box moves, the adhesive tape completely seals the opening of the foam box and on both sides. After the foam box leaves, the rear sealing wheel 210 will drive the front sealing wheel 209 back to the initial state under the restoring force of the spring 208. At the same time, the blade 212 quickly falls and cuts off the adhesive tape in an instant. When the foam box passes through the rear sealing wheel 210, the rear sealing wheel 210 will again press the sealing adhesive tape to achieve the sealing of the upper and lower horizontal surfaces and the two sides of the foam box.

[0067] The above-described specific embodiments further specifically describe the technical problems, technical solutions and beneficial effects solved by the present application. It should be understood that the above-described embodiments are merely specific embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
