[0002] Paper-plastic packaging machines are important equipment for the automatic packaging of paper-plastic powders. They are mainly used for the plastic sealing of products and are widely used in many industries such as pharmaceuticals, food, biology, hardware, electronics, chemicals, textiles, and dyes.

[0003] However, existing heat-sealing devices for paper packaging suffer from item misalignment during the packaging process, which severely affects packaging quality, leading to loose packaging, uneven appearance, and reduced product competitiveness. To address these issues, there is a need for a paper packaging heat-sealing device that can accurately position items, effectively improve packaging quality, and features an energy-saving mode. Utility Model Content

[0004] In order to overcome the shortcomings of existing paper packaging heat sealing devices that affect packaging quality due to the misalignment of the items, this utility model provides a paper packaging heat sealing device with an energy-saving mode.

[0005] The technical solution is as follows: A paper packaging heat sealing device with an energy-saving mode includes a base, conveyor belts, a lower mold, a first cylinder, an upper mold, a sensor, a fixed seat, a rotating shaft, a positioning plate, a rotating plate, a torsion spring, a second cylinder, and a pusher frame. Two conveyor belts are mounted on the base, and a lower mold is located in the center of the base, installed between the two conveyor belts. A first cylinder is fixed at the upper center of the base, and its piston is connected to the upper mold. A sensor is mounted on the upper mold, and the sensor has a built-in controller. Both the upper and lower molds are electrically connected to the controller. A fixed seat is located at one end of the base, and two rotating shafts are rotatably mounted on the fixed seat. A positioning plate and a rotating plate are respectively mounted at the upper and lower ends of the two rotating shafts. Torsion springs are wound around the outer sides of both rotating shafts, connecting the rotating plate and the fixed seat. A second cylinder is mounted on the base, and its piston is connected to a pusher frame, which contacts the two rotating plates.

[0006] Furthermore, it also includes an electric push rod, a cooling cover, a cooling pipe, a ventilation plate, a connecting pipe, an air intake cover, and an air pump. An electric push rod is located in the center of the base, and a cooling cover is fixed on the push rod of the electric push rod. A cooling pipe is installed inside the cooling cover, and a ventilation plate is installed at the bottom of the cooling cover. The ventilation plate has multiple through holes. An air intake cover is located on the base, and the two ends of the connecting pipe are connected to the cooling cover and the air intake cover, respectively. An air pump is located at the connection between the cooling cover and the connecting pipe.

[0007] Furthermore, the length and width of the cooling shroud are greater than the heat-sealed area of ​​the paper packaging.

[0008] Furthermore, there are two air pumps, two connecting pipes, and two suction hoods. The two connecting pipes are respectively connected to both ends of the cooling hood. Two air pumps are installed at the connection points between the connecting pipes and the cooling hood. The other ends of the two connecting pipes are respectively connected to two suction hoods.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A heat-sealing device for paper packaging with an energy-saving mode, such as Figures 1-6 As shown, the device includes a base 1, conveyor belts 2, a lower mold 4, a first cylinder 5, an upper mold 6, a sensor 7, a fixed base 8, a rotating shaft 9, a positioning plate 10, a rotating plate 11, a torsion spring 12, a second cylinder 13, and a pusher frame 14. Two conveyor belts 2 are mounted on the base 1, and the lower mold 4 is located in the center of the base 1, installed between the two conveyor belts 2. The first cylinder 5 is fixed to the upper center of the base 1, and its piston is connected to the upper mold 6. The upper mold 6 is equipped with a sensor 7, which has a built-in controller. Both the upper mold 6 and the lower mold 4 are electrically connected to the controller. The upper mold 6 and the lower mold 4 are heated to perform heat sealing operation on the paper. One end of the base 1 is provided with a fixed seat 8. Two rotating shafts 9 are rotatably provided on the fixed seat 8. The upper and lower ends of the two rotating shafts 9 are respectively provided with a positioning plate 10 and a rotating plate 11. Torsion springs 12 are wound around the outside of the two rotating shafts 9. The torsion springs 12 connect the rotating plate 11 and the fixed seat 8. The base 1 is provided with a second cylinder 13. The piston of the second cylinder 13 is connected to a push frame 14. The push frame 14 is in contact with the two rotating plates 11.

[0024] When using this equipment to package paper products, conveyor belt 2 transports the paper products to the right. Second cylinder 13 drives pusher frame 14 to slide on guide plate 15. Pusher frame 14 pushes rotating plate 11 and positioning plate 10 to rotate, causing torsion spring 12 to deform. Positioning plate 10 positions the paper products to prevent positional deviation from affecting heat sealing quality. Upper mold 6 and lower mold 4 are preheated. When the paper products pass lower mold 4, first cylinder 5 drives upper mold 6 to descend. The two work together to achieve heat sealing of the paper products. Sensor 7 can monitor whether there are paper products on the left conveyor belt 2. When there are no paper products, upper mold 6 and lower mold 4 stop heating, and the equipment stops packaging in time, achieving energy saving.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes an electric push rod 16, a cooling cover 17, a cooling pipe 18, a ventilation plate 19, a connecting pipe 20, an air suction hood 21, and an air pump 23. An electric push rod 16 is located in the center of the base 1. The cooling cover 17 is fixed to the push rod of the electric push rod 16. The length and width of the cooling cover 17 are larger than the heat-sealing area of ​​the paper packaging. A cooling pipe 18 is located inside the cooling cover 17. A ventilation plate 19 is installed at the bottom of the cooling cover 17, and the ventilation plate 19 has multiple through holes. An air suction hood 21 is located on the base 1. The two ends of the connecting pipe 20 are connected to the cooling cover 17 and the air suction hood 21, respectively. An air pump 23 is located at the connection point between the cooling cover 17 and the connecting pipe 20. There are two air pumps 23, two connecting pipes 20, and two air suction hoods 21. The two connecting pipes 20 are connected to the two ends of the cooling cover 17, respectively. Two air pumps 23 are installed at the connection points between the connecting pipes 20 and the cooling cover 17, and the other ends of the two connecting pipes 20 are connected to the two air suction hoods 21, respectively. After the paper products are packaged, they still retain residual heat. The electric push rod 16 moves the cooling cover 17 toward the paper products. The air pump 23 operates to generate negative pressure. External air enters the connecting pipe 20 through the suction cover 21. After the air is cooled by the cooling pipe 18, the cold air is blown out from the through hole of the ventilation plate 19, which cools the packaged paper products in time, ensuring the quality of heat sealing and preventing workers from accidentally touching the hot paper products and getting burned. The cooling cover 17 is equipped with connecting pipes 20 at both ends, and the two air pumps 23 increase the suction efficiency and improve the cooling speed, which is conducive to the rapid cooling of the paper products.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a pulley assembly 3, which connects the two conveyor belts 2. One of the conveyor belts 2 contains a motor. When the motor drives the left conveyor belt 2, the pulley assembly 3 transmits power, driving the right conveyor belt 2. The two conveyor belts 2 transport the paper to the right. The pulley assembly 3 enables one motor to drive two conveyor belts 2, achieving the effect of saving energy.

[0027] like Figures 1-4 As shown, it also includes a guide plate 15, which is provided on the fixed base 8, and the push frame 14 is slidably connected to the guide plate 15. When the push frame 14 slides on the guide plate 15, the guide plate 15 guides the sliding direction of the push frame 14 and assists the push frame 14 to slide smoothly.

[0028] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a filter screen 22, which is installed on the outside of the suction hood 21. The filter screen 22 installed on the suction hood 21 can block large debris, prevent debris from clogging the connecting pipe 20, and avoid affecting the cooling effect of the device.

[0029] The pusher frame 14 adopts a semi-circular structure design at one end, and its arc-shaped end face contacts the rotating plate 11, providing a smooth contact interface, reducing the friction generated when the pusher plate pushes the rotating plate 11 to rotate, and ensuring the stable rotation of the rotating plate 11.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
