Description

TECHNICAL FIELD

[0001] The present application relates to the field of card packaging, in particular to a sealing device of a bagging machine. BACKGROUND

[0002] With the wide application of card, sheet, box or other products, the market demands for high-efficiency, precision and automatic new bagging machines are increasingly urgent. Under the background of deep integration of digital economy and intelligent manufacturing, traditional manual or semi-automatic packaging methods have been difficult to meet the needs of large-scale production, especially in terms of product quality consistency, production efficiency and cost control. There are significant shortcomings. The current new automatic bagging machine generally includes a sealing device for sealing the bag opening of a self-adhesive bag containing a card, sheet, box or other product. The self-adhesive bag needs to be bent twice when it is sealed. The first bending is to make the bag tongue of the self-adhesive bag turn from a horizontal state to a vertical state to complete the initial closure of the self-adhesive bag. The second bending is to make the bag tongue of the self-adhesive bag fixed with the bag body of the self-adhesive bag.

[0003] The existing sealing device generally includes a bending plate for bending the bag tongue of the self-adhesive bag and a sealing plate for sealing. When the bag tongue of the self-adhesive bag passes through the bending plate, it is bent from a horizontal state to a vertical state. When the bag tongue of the self-adhesive bag is bent to a vertical state, the sealing plate moves towards the bag tongue of the self-adhesive bag and pushes the bag tongue of the self-adhesive bag to bend again towards the bag body of the self-adhesive bag until the bag tongue of the self-adhesive bag is fixed with the bag body of the self-adhesive bag.

[0004] In the process of pushing the bag opening of the self-adhesive bag to bend and complete the fixation of the bag tongue of the self-adhesive bag with the bag body of the self-adhesive bag, the bag tongue of the self-adhesive bag is not easy to maintain a flat state and is prone to wrinkles, which leads to poor quality of the fixation of the bag tongue of the self-adhesive bag with the bag body of the self-adhesive bag. SUMMARY

[0005] In order to improve the quality of the fixation of the bag tongue of the self-adhesive bag with the bag body of the self-adhesive bag, the present application provides a sealing device of a bagging machine.

[0006] The sealing device of the bagging machine provided by the present application adopts the following technical scheme:

[0007] A sealing device of a bagging machine, comprising a sealing seat and a sealing mechanism, the sealing mechanism is arranged on the sealing seat, the sealing mechanism comprises a sealing plate, a pressing plate, a first driving assembly and a second driving assembly, the sealing plate and the pressing plate are slidably connected to the sealing seat, the pressing plate can slide towards or away from the sealing plate, the first driving assembly is used to drive the sealing plate to slide, and the second driving assembly is used to drive the pressing plate to slide.

[0008] Optionally, the first drive assembly includes a first drive motor, a first drive gear, and a first drive rack. The first drive motor is disposed on the adhesive sealing seat, the first drive gear is coaxially fixed to the output shaft of the first drive motor, and the first drive rack is slidably engaged with the adhesive sealing seat and fixedly connected to the adhesive sealing plate.

[0009] Optionally, the sealing mechanism further includes at least one sealing guide rod, which is slidably fitted to the sealing seat and fixedly connected to the pressure plate, and the sealing plate is slidably fitted to the sealing guide rod.

[0010] Optionally, the second drive assembly includes a second connecting rod, a second drive motor, a second drive gear, and a second drive rack. The second connecting rod and each of the adhesive guide rods are fixedly connected. The second drive motor is disposed on the adhesive seat. The second drive gear is coaxially fixed to the output shaft of the second drive motor. The second drive rack is slidably engaged with the adhesive seat and fixedly connected to the second connecting rod.

[0011] Optionally, the sealing mechanism further includes a first connecting rod, and the first driving assembly includes a first driving motor, a first driving gear and a first driving rack. The first driving motor is disposed on the sealing seat, the first driving gear is coaxially fixed to the output shaft of the first driving motor, and the first driving rack is slidably engaged with the sealing seat and fixedly connected to the sealing plate.

[0012] The first connecting rod slides into the sealing guide rod, the first connecting rod is fixedly connected to the first drive rack, and the first drive assembly drives the sealing plate.

[0013] Optionally, the sealing plate is provided with a soft brush, which is used to smooth the opening of the self-adhesive bag and seal the opening of the self-adhesive bag.

[0014] Optionally, the pressing plate is provided with a pressing spring, and when the pressing plate presses the opening of the self-adhesive bag to the sealing plate, the pressing spring abuts against the opening of the self-adhesive bag.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] When the sealing device of the bagging machine seals the opening of the self-adhesive bag, after the self-adhesive bag is conveyed to the sealing mechanism, the pressure plate moves towards the sealing plate until the pressure plate presses the bag flap against the sealing plate. Then, the sealing plate and the pressure plate move simultaneously towards the bag body, causing the bag flap to continuously bend and adhere to the bag body until the bag flap is fixed to the bag body. The pressure plate then presses the bag flap firmly against the sealing plate, preventing wrinkles from forming on the bag flap. Simultaneously, the bag flap and bag body... During the fixing process, the flap of the self-adhesive bag continuously bends and adheres to the body of the bag, resulting in better stability and preventing wrinkles from forming on the flap. This improves the quality of the fixation between the flap and the body, addressing the issue where the flap is prone to wrinkling and poor adhesion when the sealing plate pushes it to bend, leading to a poorly fixed fit.

[0023] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0024] This application discloses a sealing device for a bagging machine. (Refer to...) Figure 1 A sealing device for a bagging machine includes a sealing base 1 and a sealing mechanism 3, wherein the sealing mechanism 3 is disposed on the sealing base 1.

[0025] Reference Figure 1 The sealing mechanism 3 includes a sealing guide rod 31, a sealing plate 32, a pressing plate 33, a first driving assembly 34, a first connecting rod 35, and a second driving assembly 36. The sealing guide rod 31 is slidably fitted to the sealing seat 1. The sealing guide rod 31 is fixedly connected to the pressing plate 33. The sealing plate 32 is slidably fitted to the sealing guide rod 31 so that both the sealing plate 32 and the pressing plate 33 are slidably fitted to the sealing seat 1. The pressing plate 33 can slide towards or away from the sealing plate 32. When the sealing mechanism 3 performs sealing, the pressing plate 33 presses the flap of the self-adhesive bag against the sealing plate 32.

[0026] Reference Figure 2 The sealing mechanism 3 also includes a first drive assembly 34 and a first connecting rod 35. The first drive assembly 34 includes a first drive motor 341, a first drive gear 342 and a first drive rack 343. The first drive motor 341 is fixedly mounted on the sealing base 1. The first drive gear 342 is coaxially fixed to the output shaft of the first drive motor 341. The first drive rack 343 is slidably engaged with the sealing base 1 and fixedly connected to the sealing plate 32. The first connecting rod 35 is slidably engaged with both sealing guide rods 31. The first connecting rod 35 is fixedly connected to the first drive rack 343.

[0027] Reference Figure 2 The sealing mechanism 3 also includes a second drive assembly 36, which includes a second connecting rod 361, a second drive motor 362, a second drive gear 363, and a second drive rack 364. The second connecting rod 361 and each sealing guide rod 31 are fixedly connected. The first connecting rod 35 is located between the second connecting rod 361 and the sealing plate 32. The second drive motor 362 is fixedly mounted on the sealing seat 1. The second drive gear 363 is coaxially fixed to the output shaft of the second drive motor 362. The second drive rack 364 is slidably fitted on the sealing seat 1 and fixedly connected to the second connecting rod 361.

[0028] Reference Figure 2When the sealing mechanism 3 bends and seals the opening of the self-adhesive bag, the second drive assembly 36 is driven, which moves the pressure plate 33 toward the sealing plate 32 until the pressure plate 33 presses the flap of the self-adhesive bag against the sealing plate 32. Then the first drive assembly 34 is driven, which moves the sealing plate 32 toward the body of the self-adhesive bag. At the same time, the second drive assembly 36 and the first drive assembly 34 push the pressure plate 33 to move in the same direction and at the same speed. Alternatively, the first drive assembly 34 is driven, which moves the sealing plate 32 toward the pressure plate 33 until the sealing plate 32 presses the flap of the self-adhesive bag against the pressure plate 33. Then the second drive assembly 36 is driven, which moves the pressure plate 33 toward the body of the self-adhesive bag in the same direction and at the same speed as the first drive assembly 34. This makes the flap of the self-adhesive bag and the body of the self-adhesive bag sealed and fixed.

[0029] After the sealing mechanism 3 completes the sealing and fixing of the self-adhesive bag, the first drive assembly 34 is driven, which moves the sealing plate 32 away from the self-adhesive bag and simultaneously moves the first connecting rod 35 away from the self-adhesive bag. When the first connecting rod 35 moves to a certain distance, the distance between the sealing plate 32 and the pressing plate 33 is reset to the initial distance between the sealing plate 32 and the pressing plate 33. Then, the second drive assembly 36 is driven, which pushes the second connecting rod 361 away from the self-adhesive bag in the same direction and at the same speed as the first drive assembly 34. The second connecting rod 361 moves the pressing plate 33 away from the self-adhesive bag, so that the pressing plate 33 and the sealing plate 32 maintain the initial distance and move away from the self-adhesive bag at the same time until the sealing mechanism 3 is reset.

[0030] Reference Figure 3 and Figure 4 The sealing plate 32 may be provided with a soft brush 321, which is used to smooth the opening of the self-adhesive bag and make the opening of the self-adhesive bag stick together. The material of the soft brush 321 can be a soft material such as a brush, silicone, or rubber. This embodiment does not limit this. The pressing plate 33 may be provided with a pressing spring 331. When the pressing plate 33 presses the bag tongue of the self-adhesive bag to the sealing plate 32, the pressing spring 331 abuts against the bag tongue of the self-adhesive bag. In this embodiment, the pressing spring 331 is elastic.

[0031] The principle of the sealing device of a bagging machine according to an embodiment of this application is as follows: The flap of a self-adhesive bag is conveyed to the sealing mechanism 3 in a vertical state. The pressing plate 33 moves towards the sealing plate 32, or the sealing plate 32 moves towards the pressing plate 33, until the sealing plate 32 and the pressing plate 33 press the flap of the self-adhesive bag tightly. Then, the sealing plate 32 and the pressing plate 33 move simultaneously and in the same direction towards the body of the self-adhesive bag, causing the flap of the self-adhesive bag to continuously bend and adhere to the body of the bag until the flap and body are fixed. The pressing plate 33 then presses the flap of the self-adhesive bag against the sealing plate 32, thus sealing the flap of the self-adhesive bag. It is less prone to wrinkles. Furthermore, when the flap of the self-adhesive bag is fixed to the bag body, the flap continuously bends and adheres to the bag body, resulting in better stability and preventing wrinkles. This improves the quality of the fixation between the flap and the bag body, addressing the problem of the flap not maintaining a flat surface and prone to wrinkles during the process of the sealing plate 32 pushing the flap to bend and fix the flap to the bag body, which leads to poor fixation quality.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
