Description

Technical Field

[0001] The present invention belongs to the technical field of tea packaging, and particularly relates to a fully automatic tea packaging machine. Background Art

[0002] In order to facilitate storage and making tea, most of the tea in China currently adopts small packages of 5 to 10 grams. According to the usage requirements of customers, such packages are generally divided into two methods. The first is to use only one outer bag for packaging, that is, directly put the tea into the outer bag, and then seal the outer bag. This method of packaging is fast. The second uses an inner and outer bag packaging. First, put the tea into the inner bag, then put the inner bag into the outer bag, and then seal it. Using this packaging method can better protect the tea, and at the same time, it is not easy to cause the tea to scatter when the outer bag is removed.

[0003] The existing packaging method using inner and outer bags is generally carried out manually. Put the small inner bag of tea into the outer bag, and then seal it with a sealing machine. Manual loading is prone to errors in the number of bags loaded, and the work efficiency is slow. After loading, the tea in the small bag is concentrated on one side of the tea bag, with uneven distribution and low loading efficiency. Summary of the Invention

[0057] As Figure 6 and Figure 9 shown, the lower suction cup assembly 61 includes a suction cup cylinder 611, a first connecting plate 612 and a first air suction cup 613. The lower end of the suction cup cylinder 611 is connected to the lead screw 72 through a slider 614.

[0058] As Figure 10 and Figure 11As shown in the figure, the lower heat-sealing assembly 81 includes a lower heat-sealing cylinder 811 and a lower heat-sealing plate 812. The lower heat-sealing cylinder 811 is fixed below the support table 10, and the lower heat-sealing plate 812 is connected to the piston rod of the lower heat-sealing cylinder 811. The upper heat-sealing assembly 82 includes a heat-sealing support frame 821, an upper heat-sealing cylinder 822, and an upper heat-sealing plate 823.

The upper heat-sealing plate 823 corresponds to the lower heat-sealing plate 812.

[0059] As Figure 2 shown in the figure, the pushing mechanism 9 is arranged on one side of the support table 10 and is used to push small packets of tea into empty tea bags. The pushing mechanism 9 includes a pushing cylinder 91 and a pushing plate 92. The pushing mechanism 9 includes a pushing cylinder 91 and a pushing plate 92. The pushing cylinder 91 is installed on one side of the tea conveying mechanism 2, and the pushing plate 92 is connected to the pushing cylinder 91. The pushing plate 92 corresponds to the discharge port 251 of the tea packet baffle 25 on the tea conveying mechanism 2.

[0060] As Figure 6 and Figure 7 shown in the figure, on the support table 10 between the packaging mechanism 8 and the pushing mechanism 9, there is an opening piece 11 for limiting the positions of both sides inside the empty tea bag, and on the support table 10 on one side of the packaging mechanism 8, there is a discharge groove 12.

[0061] The working principle of the present invention is:

[0062] Stacking of small packets of tea: Place the small packets of tea at the loading end 33 of the conveyor belt 31. The conveyor belt 31 continuously conveys the small packets of tea to the unloading end 34 and then into the lower tea packet box 24 for stacking. The four stacking stations of the stacking mechanisms 3 at both ends of the tea conveyor 2 simultaneously perform conveying and stacking. Each station stacks 6 packets each time, for a total of 24 packets. The 24 small packets of tea are stacked in the tea packet box 24. The stepping motor drives the driving sprocket 21 to rotate. The subsequent empty tea packet boxes 24 enter the feeding end 26 for continued stacking, and the tea packet boxes 24 already filled with small packets of tea move forward. When reaching the tea stack vibrating mechanism 4, the air vibrator 46 drives the vibrating chassis 43 to vibrate. The vibrating chassis 43 acts on the small packets of tea. Since when stacking by falling, the tea in the small packets of tea will tilt to one side, resulting in uneven distribution of the tea in the small packets of tea. Through the vibration of the vibrating chassis 43, the tea in the small packets of tea is evenly distributed. Then the stacked tea continues to move towards the discharge end 27. The number of packets filled in the present invention can be counted according to the infrared light sensor. When the number of small packets of tea in the tea packet box 24 reaches the set requirement, the stepping motor rotates once.

[0063] Bagging and Sealing: Empty tea bags are stacked one by one in the bag storage mechanism 5. The moving motor 61 drives the lead screw 62 to rotate. The lead screw 62 drives the suction cup cylinder 711 to move under the bag storage mechanism 5. The suction cup cylinder 711 pushes upward, and the first air suction cup 713 sucks an empty tea bag from the bottom of the bag storage mechanism 5. The first air suction cup 713 is driven by the lead screw 62 to move under the second air suction cup 722 again. At the same time, the second air suction cup 722 is opened to suck the upper surface of the empty tea bag. The suction cup cylinder 711 moves down a certain distance. Since the upper and lower ends of the empty tea bag are sucked by the first air suction cup 713 and the second air suction cup 722, the empty tea bag is opened. The upper suction cup assembly 72 and the lower suction cup assembly 71 move simultaneously, and the opening piece 11 is inserted into the opening of the empty tea bag to limit both ends of the empty tea bag. The pushing cylinder 91 pushes the push plate 92 to push the small package of tea in front of the push plate into the empty tea bag. Then, the upper heat sealing cylinder 822 moves down, and the lower heat sealing cylinder 811 moves up. The upper heat sealing plate 823 and the lower heat sealing plate 812 cooperate with each other to seal the opening of the tea bag. At the same time, the upper suction cup assembly 72 and the lower suction cup assembly 71 are removed. The lower suction cup assembly 71 returns to the bottom of the bag storage mechanism 5 to store bags again. After heat sealing, the tea bag falls into the discharge chute 12 under the action of gravity for discharging, completing the packaging.

[0064] The above has schematically described the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only the implementation scheme of the present invention, and the actual structure is not limited thereto. Therefore, those of ordinary skill in the art, inspired by it, without departing from the purpose of the present invention creation, without creative design, structures and embodiments similar to this technical solution should all fall within the protection scope of the present invention.
