[0028] Please see Figure 1 , Figure 3 and Figure 4 The feeding assembly 1 includes a frame body 11, with rollers 15 rotatably connected to both sides of the frame body 11. Adjacent rollers 15 are connected by a transmission belt, and a conveyor belt 14 is provided on the outer side of adjacent rollers 15. Specifically, the conveyor belt 14 is a belt. A drive motor 13 is provided on one side of any roller 15. The drive motor 13 is connected to a control switch via a wire. The drive motor 13 is fixedly installed on the frame body 11, and the output shaft of the drive motor 13 is connected to the corresponding roller 15. When the drive motor 13 is turned on, the conveyor belt 14 can transport the express waybill from left to right.
[0029] Furthermore, baffles 12 are symmetrically arranged on the front and rear sides of the conveyor belt 14. The baffles 12 are movably sleeved on the roller shaft 15. Screws 16 are rotatably connected to the opposite faces of the symmetrical baffles 12. Screw sleeves 17 are threadedly connected between adjacent screws 16. After rotating the screw sleeves 17, the distance between adjacent screws 16 can be reduced or increased, thereby realizing the adjustment of the distance between the symmetrical baffles 12. As needed, it can meet the needs of conveying sheet of different sizes.
[0030] Please see Figure 1 , Figure 3 and Figure 5 The coating assembly 2 includes a mounting frame 21, which is fixedly mounted to the main frame 11. An upper winding shaft 22 and a lower winding shaft 23 are rotatably connected to the upper and lower sides of the mounting frame 21, respectively. A transparent film 24 is provided on both the upper winding shaft 22 and the lower winding shaft 23. Notably, the ends of the transparent films 24 wound on the upper winding shaft 22 and the lower winding shaft 23 are connected by heat fusion. Figure 1 and Figure 3 As shown, the connected transparent film 24 wraps around the left side of the mounting bracket 21.
[0031] Furthermore, guide members 25 are provided on both sides of the transparent film 24. The guide members 25 are fixedly installed on the mounting bracket 21. The guide members 25 form a V-shaped angle of less than 90 degrees, and the larger opening side of the guide members 25 faces away from the support base 31. The guide members 25 can press down on both sides of the transparent film 24, making it easier for it to enter the edge sealing assembly 3.
[0032] In this example, several rollers are evenly arranged on the mounting frame 21. The rollers are connected to the roller shafts 15 at corresponding positions through the transmission assembly 7. The transmission assembly 7 includes a transmission belt and a corresponding pulley group. The pulley group is connected through the transmission belt, which can transmit the rotational force of the roller shafts 15 to the rollers, thereby conveying the workpiece above the rollers from left to right.
[0033] Please see Figure 1 and Figure 5 The edge sealing assembly 3 includes a support base 31, which is fixedly mounted on the mounting frame 21. An electric push rod 33 is fixedly mounted on the upper center of the support base 31. Guide rods 32 are provided on both the front and rear sides of the electric push rod 33. The guide rods 32 are movably inserted into the support base 31, and a push plate 34 is fixedly mounted on the lower ends of the guide rods 32 and the electric push rod 33. The electric push rod 33 is connected to a control switch via wires, enabling it to drive the push plate 34 to move upwards or downwards. Slide rods 30 are arranged in a square pattern on the upper surface of the inner cavity of the support base 31. The center lines of the slide rods 30 and the guide rods 32 are parallel, and the slide rods 30 are higher than the mounting frame 21. Upper plastic sealing components 37 are connected to both the front and rear sides of the push plate 34 via connectors 35. A return spring 36 is sleeved on the connector 35, and the return spring 36 is located between the push plate 34 and the upper plastic sealing component 37. A lower plastic seal 38 is provided below the upper plastic seal 37. Both the upper plastic seal 37 and the lower plastic seal 38 are sleeved on the slide rod 30. The upper plastic seal 37 and the lower plastic seal 38 are connected by a linkage 391. The upper and lower sides of the linkage 391 are connected to the upper plastic seal 37 and the lower plastic seal 38 on the corresponding sides through auxiliary pins 392. The outer surfaces of the upper plastic seal 37 and the lower plastic seal 38 are provided with sliding grooves for the auxiliary pins 392 to slide. The linkage 391 is connected to the support base 31 through the main pin 39. The push plate 34 is perpendicular to the upper plastic seal 37 and the lower plastic seal 38, and the upper plastic seal 37 and the lower plastic seal 38 are parallel to each other. Guided by the guide member 25, the transparent film 24 can quickly enter between the upper sealing member 37 and the lower sealing member 38. After the electric push rod 33 is opened, the push plate 34 moves from top to bottom through the guide rod 32. At this time, the upper sealing member 37 moves with the push plate 34. Through the connection of the linkage member 391, the upper sealing member 37 and the lower sealing member 38 move closer to each other, and the two sides of the transparent film 24 can be sealed.
[0034] Please see Figure 1 and Figure 5 The cutting assembly 4 includes a cutting plate 41, a cutting blade 42, and a heating element 43. The cutting plate 41 is fixedly mounted on the push plate 34, and the cutting plate 41 and cutting blade 42 are also fixedly mounted. The cutting blade 42 is movably engaged with the heating element 43, which is fixedly mounted on the mounting bracket 21. The drive motor 13, heat shrink machine 5, electric push rod 33, and heating element 43 are all electrically connected to the controller and power supply equipment via wires. The spacing between adjacent guide members 25, the cutting plate 41, and the guide plate 62 are all larger than the spacing between the symmetrical baffles 12. The cutting assembly 4 is powered by the electric push rod 33. After the electric push rod 33 moves, it can drive the cutting plate 41 and cutting blade 42 to move downwards, thus enabling the cutting operation of the next process to be carried out simultaneously with the edge sealing process of the previous process. This results in high utilization and further reduces costs.
[0035] In this example, the feeding assembly 6 includes a collection frame 61 and a guide plate 62. The collection frame 61 is located on the right side of the mounting frame 21, and the guide plate 62 is fixedly installed on the mounting frame 21. The guide plate 62 facilitates the entry of the packaged express waybill into the collection frame 61.
[0036] Working Principle: This fully automatic heat shrink packaging machine for express delivery labels operates by conveying stacks of labels from left to right via the conveyor belt 14. Once the labels enter the mounting frame 21, they pull the transparent film 24 from left to right. At this time, the guide component 25 gradually reduces the distance between the upper and lower transparent films 24, facilitating their entry into the sealing assembly 3. After entering the sealing assembly 3, the electric push rod 33 opens, and guided by the guide rod 32, the film... The push plate 34 moves downwards, and the upper sealing element 37 follows the push plate 34. Through the connection of the linkage 391, the upper sealing element 37 and the lower sealing element 38 move closer together, allowing for edge sealing of both sides of the transparent film 24. As the waybill is conveyed from left to right, the electric push rod 33 moves, pushing out and driving the cutting plate 41 and cutting blade 42 downwards. This allows for cutting operations in the next process while the previous edge sealing is being performed. After edge sealing and cutting, the heat shrink machine 5 heat shrinks the transparent film 24 to fit the waybill. After completion, the packaged waybill is automatically guided into the collection frame 61 by the guide plate 62.
[0037] It is worth noting that the startup sequence of the above-mentioned components can be set by programming the controller to determine their startup time, thereby meeting the needs of continuous processing.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
