Abstract
Description
Technical Field
[0001] This utility model relates to the field of express bag sealing technology, and in particular to an express bag sealing adhesive coating device. Background Technology
[0002] Express delivery, also known as mailing, is a common way to transport goods. When express bags used for mailing paper documents need to be sealed for preservation, they are often sealed with glue or paste.
[0003] In the application document CN202022082766.2, the inflation device 7 transmits gas through the air guide pipe 5 to the inside of the glue storage cylinder 3. At this time, the movable block 6 pushes and squeezes the glue inside the glue storage cylinder 3, so that the glue enters the dispersion cylinder 8 through the connecting pipe 9, and finally adheres to the sealing of the express bag through the glue leakage hole 10. This makes the glue application process of sealing the express bag simple and convenient, the glue is applied evenly, and the work efficiency and glue application effect are improved.
[0004] After the glue application is completed, a small amount of glue will remain at the bottom of the glue leakage hole. The residual glue is prone to falling off as the dispersing cylinder moves upward. The fallen glue falls into the limiting frame and will stick to the surface of the next quick bag that needs to be glued, thus affecting the glue application effect of the quick bag. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the existing technology where residual glue at the bottom of the glue leakage hole falls into the limiting frame and sticks to the surface of the next express bag that needs to be glued, thus affecting the glue application effect of the express bag. Therefore, this invention proposes a courier bag sealing and glue application device.

[0008] Preferably, the support platform and the support plate are an integral structure, and an anti-slip pad, which is a rubber pad, is fixedly connected to the bottom end of the support platform.
[0009] Preferably, guide rods are fixedly connected to both sides of the upper end of the box, and one end of each guide rod passes through the support plate.
[0010] Preferably, the second electric telescopic rod is provided in two sets and is symmetrically arranged on both sides of the upper end of the box.
[0011] Preferably, the elastic ring is a heat-resistant rubber ring.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1: Refer to Figure 1-3 A sealing and gluing device for express delivery bags includes a support platform 1, a support plate 2 fixedly connected to the upper end of the support platform 1, the support platform 1 and the support plate 2 being an integral structure, an anti-slip pad (rubber pad) fixedly connected to the bottom end of the support platform 1, a first electric telescopic rod 3 fixedly connected to the upper end of the support plate 2, the telescopic end of the first electric telescopic rod 3 passing through the support plate 2 and fixedly connected to a box body 4, guide rods 5 fixedly connected to both sides of the upper end of the box body 4, one end of each guide rod 5 passing through the support plate 2, a plurality of conical holes 6 evenly spaced along the length direction at the bottom end of the box body 4, a piston plate 7 slidably connected to the box body 4, and a second electric telescopic rod for driving the piston plate 7 to move vertically connected to the upper end of the box body 4. 8. Two sets of second electric telescopic rods 8 are provided and symmetrically arranged on both sides of the upper end of the box body 4. An elastic ring 10 is fixedly connected to the bottom end of the box body 4. The elastic ring 10 is a heat-resistant rubber ring. Several conical holes 6 are located inside the elastic ring 10. A limiting frame 9 for limiting the express bag is connected to the upper end of the support platform 1. A first mounting groove is opened at the upper end of the support platform 1. A sensor 11 is connected in the first mounting groove. A second mounting groove is opened on both sides of the upper end of the support platform 1. A heating plate 12 is connected in each mounting groove. The heating plate 12 is located inside the limiting frame 9. A controller is fixedly connected to the support plate 2. The controller signal connects the first electric telescopic rod 3, the second electric telescopic rod 8, the sensor 11 and the heating plate 12.
[0025] Work process:
[0026] When sealing and applying glue, the opening of the express bag is placed inside the limiting frame 9. The limiting frame 9 limits the opening of the express bag. After the express bag is placed, it is sensed by the sensor 11 and the signal is transmitted to the controller. The controller controls the first electric telescopic rod 3 to be powered on and started. After the first electric telescopic rod 3 is started, it drives the box 4 to move downward a set distance. The box 4 moves smoothly under the guidance of the guide rod 5. After the box 4 moves downward a set distance, it is squeezed and contacted with the opening of the express bag through the elastic ring 10.
[0027] The controller controls the second electric telescopic rod 8 to move the piston plate 7 downwards by a set distance and then resets it. After the piston plate 7 moves downwards, the space between it and the bottom of the box 4 decreases, and the pressure between the piston plate 7 and the bottom of the box 4 increases, thereby squeezing the glue out from the conical hole 6. The squeezed glue falls onto the opening of the express bag. During the process of the piston plate 7 moving upwards to reset, the space between it and the bottom of the box 4 increases, and the pressure between the piston plate 7 and the bottom of the box 4 decreases, resulting in a negative pressure between the piston plate 7 and the bottom of the box 4. External gas enters the box 4 through the conical hole 6. During the gas entry process, the glue at the bottom of the conical hole 6 is drawn into the box 4, so that no glue remains at the bottom of the box 4. The glue cannot be released from the conical hole 6 under the action of gravity. After the glue is applied, the glue dripping from the conical hole 6 is prevented, and the glue sticks to the surface of the express bag.
[0028] Example 2: After applying glue to the opening of the express bag, it is inconvenient to fold and cover the opening, making it difficult to seal. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the box body 4 is connected to an indentation device 13 for indenting express bags. The indentation device 13 includes a groove plate 131. One side of the groove plate 131 is fixedly connected to the box body 4. An indentation plate 132 is slidably connected to the groove plate 131. A spring 133 is fixedly connected to the upper end of the indentation plate 132. One end of the spring 133 is fixedly connected to the groove plate 131. Several springs 133 are provided and are evenly spaced along the length direction of the indentation plate 132. The bottom end of the indentation plate 132 is a pointed structure. An indentation groove is opened at the upper end of the support platform 1. The indentation groove cooperates with the pointed structure.
[0029] As the box 4 moves downward, it drives the groove plate 131 to move downward. The groove plate 131 drives the indentation plate 132 to move downward through the spring 133. The pointed structure of the indentation plate 132 contacts the opening of the express bag. After the indentation groove cooperates with the pointed structure, it indents the opening of the express bag. The indentation groove limits the bottom end of the indentation plate 132, so that the indentation plate 132 squeezes the spring 133. The spring 133 generates elastic force after being compressed. The elastic force generated by the spring 133 makes the indentation plate 132 press tightly against the opening of the express bag, creating an indentation at the opening of the express bag, which facilitates folding and sealing at the opening of the bag, thus facilitating glue sealing.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
