Description

Technical Field

[0001] This utility model relates to the field of tea packaging technology, and more specifically, to the feeding mechanism of a wrapping machine for tea packaging. Background Technology

[0002] Tea packaging machines, also known as tea laminating machines, are used to coat tea boxes of various sizes and types depending on the weight and grade of the tea. To ensure the airtightness of the tea packaging boxes, a laminating machine is generally used to coat them.

[0003] A search revealed that application CN202323498792.3, entitled "A Tea Outer Packaging Laminating Machine," describes a tea outer packaging laminating machine that can only clean the top surface of the tea outer packaging box, leaving the bottom and sides uncleaned. This allows dust and impurities adhering to the bottom and sides of the tea outer packaging box to affect the laminating process. The proposed solution involves opening the first and second conveyor belts, allowing the tea outer packaging to pass through the first conveyor belt first. As the tea outer packaging passes between two first cleaning rollers, the rollers rotate, cleaning the sides of the tea outer packaging box. Then, when one top end of the tea outer packaging box abuts against the lower surface of a third cleaning roller, the third cleaning roller moves upward, causing two movable blocks to move in their corresponding slots. The inner and outer surfaces slide upwards, causing the two springs to deform and stretch, thus allowing the third cleaning roller to better adhere to the upper surface of the tea packaging box. When the tea packaging box passes between the second and third cleaning rollers, it drives the second and third cleaning rollers to rotate. The rotating second and third cleaning rollers clean the top and bottom surfaces of the tea packaging box, thereby removing dust and impurities adhering to the surface of the tea packaging box. This reduces the likelihood of the film not adhering well to the tea packaging box or wrinkling during the subsequent lamination process. However, in actual operation, this application can only clean the side walls, top, and bottom surfaces of the tea packaging box. The two end surfaces of the tea packaging box cannot be effectively cleaned. The coverage area could be further expanded. At the same time, the structure of this application is complex, and the dust generated during cleaning is prone to escape and leakage. The work efficiency could be further improved.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a feeding mechanism for a tea packaging wrapping machine is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the feeding mechanism of the tea packaging wrapping machine according to an embodiment of the present invention includes a main feeding channel 1 and a side feeding channel 5. The side feeding channel 5 is connected to one side of the main feeding channel 1, and a conveyor 16 is installed inside the side feeding channel 5. The conveyor 16 is driven by a stepper motor and extends into the main feeding channel 1. A ring box 2 is fixedly connected to one end of the main feeding channel 1, and a first dust suction hole 4 is opened on the inner surface of the ring box 2. A first brush bristle 3 is fixedly installed on the inner surface of the ring box 2 outside the first dust suction hole 4. The first brush bristle 3 is distributed in four directions. Side boxes 17 are fixedly installed on the side walls of the side feeding channel 5 on both sides of the conveyor 16, and a second dust suction hole 1 is opened on one side surface of the side box 17. 9. A second brush bristle 18 is fixedly installed on the outer side of the second dust suction hole 19 on the surface of the side box 17. An electric cylinder 14 is fixedly connected to the other end of the main feeding channel 1, and a push plate 15 is installed at the output end of the electric cylinder 14. A dust collection box 9 is fixedly installed on the top surface of the main feeding channel 1, and an air pump 12 is fixedly installed on the top surface of the dust collection box 9. The input end of the air pump 12 is connected to the dust collection box 9 through the air suction pipe 13. A dust conveying pipe 6 is connected through one side surface of the dust collection box 9, and the dust conveying pipe 6 is connected through the first dust suction pipe 7 and the second dust suction pipe 8 to the ring box 2 and the side box 17 respectively. A perforated plate 10 is fixedly installed inside the dust collection box 9, and a filter cotton 11 is fixedly installed on one side surface of the perforated plate 10. One end of the main feeding channel 1 is connected to the tea wrapping machine for feeding. The packaged tea boxes are placed on top of conveyor 16 and conveyed through the side boxes 17. The second brush 18 on the surface of the side boxes 17 cleans both ends of the tea box. Then, the tea box moves to the side of push plate 15, and electric cylinder 14 extends, pushing push plate 15 and moving the tea box into the ring box 2. After passing through the ring box 2, the tea box enters the tea wrapping machine for wrapping. As the tea box passes through the first brush 3 on the surface of the ring box 2, the first brush 3 cleans the remaining four sides of the tea box. This device can clean all six surfaces of the tea box by rotating and moving it, resulting in high cleaning and dust removal efficiency, wide coverage, and improved performance. To improve work efficiency, the vacuum pump 12 is activated when the tea packaging box is moved, drawing out the air from inside the dust collection box 9. This air is then drawn out from inside the ring box 2 and side box 17 through the dust conveying pipe 6, the first suction pipe 7, and the second suction pipe 8. This creates a negative pressure state for the first suction hole 4 and the second suction hole 19. The dust that has been swept away is drawn into the ring box 2 and side box 17 by the air pressure and then transported into the dust collection box 9 through the dust conveying pipe 6. After being filtered by the filter cotton 11, the dust remains inside the dust collection box 9, completing the dust collection process. This avoids the problem of dust escaping, maintains the cleanliness of the equipment, eliminates the trouble of frequent manual cleaning, and further improves work efficiency and ease of use.

[0031] In one embodiment, the perforated plate 10 and the filter cotton 11 are located between the dust conveying pipe 6 and the air extraction pipe 13, and the side wall of the filter cotton 11 is pressed against the inner wall of the dust collection box 9 to prevent dust leakage. The filter cotton 11 plays the role of filtering dust and preventing dust from entering the air extraction pump 12.

[0032] In one embodiment, the first suction hole 4 and the second suction hole 19 are densely distributed at equal intervals, and the diameters of the first suction hole 4 and the second suction hole 19 are the same, thereby expanding the suction range and improving the suction effect.

[0033] In one embodiment, the first bristles 3 and the second bristles 18 are densely distributed at equal intervals, and both the first bristles 3 and the second bristles 18 are made of flexible materials, thereby expanding the cleaning range and improving the cleaning effect.

[0034] In one embodiment, the stroke of the electric cylinder 14 is greater than the length of the main feed channel 1, and the electric cylinder 14 is used in conjunction with a controller to facilitate operation by the staff.

[0035] In one embodiment, both the ring box 2 and the side box 17 are hollow structures, and the ring box 2 is a rectangular ring structure. The hollow structure of the ring box 2 and the side box 17 facilitates airflow and thus facilitates dust flow.

[0036] In one embodiment, one end of the main feeding channel 1 is aligned with the feeding end of the tea wrapping machine, making it convenient to directly push the tea packaging box into the tea wrapping machine.

[0037] In one embodiment, the dust collection box 9 has a sealed door hinged to its rear facade for easy opening and cleaning of dust.

[0038] Working principle:

[0039] The packaged boxed tea is placed on top of conveyor 16 and conveyed through the side boxes 17. The second brush 18 on the surface of the side box 17 cleans both ends of the tea packaging box. Then, the tea packaging box moves to the side of push plate 15, electric cylinder 14 extends, pushes push plate 15, and pushes the tea packaging box into the ring box 2. After passing through the ring box 2, the tea packaging box enters the tea wrapping machine for wrapping. When the tea packaging box passes through the first brush 3 on the surface of the ring box 2, the first brush 3 cleans the remaining four sides of the tea packaging box. This device can clean all six surfaces of the tea packaging box by turning and moving the tea packaging box, with high cleaning and dust removal efficiency, wide coverage, and improved work efficiency. In addition to improving efficiency, when the tea packaging box is moved, the vacuum pump 12 starts to extract the air from inside the dust collection box 9. The air is then extracted from inside the ring box 2 and side box 17 through the dust conveying pipe 6, the first suction pipe 7, and the second suction pipe 8. This creates a negative pressure state for the first suction hole 4 and the second suction hole 19. The dust that has been swept away is forced by the air pressure to enter the ring box 2 and side box 17 through the first suction hole 4 and the second suction hole 19. After being transported by the dust conveying pipe 6, it enters the dust collection box 9, is filtered by the filter cotton 11, and remains inside the dust collection box 9, thus completing the dust collection and avoiding the problem of dust escaping. This maintains the cleanliness of the equipment, eliminates the trouble of frequent manual cleaning, and further improves work efficiency and ease of use.
