[0002] With the wide application of card, sheet, block or box products, the market demand for efficient, accurate and automatic bagging machines is increasingly urgent. At present, when the automatic bagging machines package card, sheet, block or box products, they generally push the card, sheet, block or box products to the double-layer packaging film, and then cut and seal the bag on both sides of the double-layer packaging film through a cutting device, thereby completing the packaging of the card, sheet, block or box products.

[0003] The existing cutting device generally includes a fixed frame, a driving cylinder and a hot cutting assembly. The fixed frame is fixedly arranged on a workbench. The driving cylinder is fixedly arranged on the fixed frame. The hot cutting assembly includes a heat insulation plate, a hot cutting knife and an abutting plate. The heat insulation plate is fixedly arranged on the piston rod of the driving cylinder. The hot cutting knife is fixedly arranged at the bottom of the heat insulation plate. The abutting plate is slidingly fitted in the heat insulation plate. A return spring is fixedly arranged between the abutting plate and the heat insulation plate. The hot cutting knife is located inside the abutting plate. The abutting plate is provided with a hot cutting groove arranged therethrough. When the hot cutting and sealing mechanism cuts and seals the bag, the driving cylinder is driven. The piston rod of the driving cylinder drives the hot cutting assembly to move towards the double-layer packaging film.

[0039] With reference to Figure 8 The heat cutting assembly 2 further comprises a lower heat cutting component 22. The lower heat cutting component 22 comprises two lower sliding rods 221, an abutting seat 222 and a connecting rod 223.

[0041] With reference to Figure 9 The driving assembly 3 comprises a main driving component 31. The main driving component 31 comprises a main driving shaft 311, a driving motor 312, a main driving wheel 313, a driven wheel 314 and a driving belt 315.

The main driving wheel 313 is coaxially and fixedly arranged on the output shaft of the driving motor 312. The driven wheel 314 is coaxially and fixedly arranged on the main driving shaft 311. The driving belt 315 is arranged on the outer circumferential surface of the main driving wheel 313 and the driven wheel 314. The driving motor 312 drives the main driving wheel 313 to rotate through the driving belt 315, thereby driving the driven wheel 314 to rotate, and driving the main driving shaft 311 to rotate.

[0042] With reference to Figure 9 The driving assembly 3 further comprises two sets of upper driving components 32, which are respectively located at two ends of the main driving shaft 311. The upper driving component 32 comprises an upper reset spring 321, an eccentric driving wheel 322 and a driving connecting rod 323. The upper reset spring 321 is located between the hot cutting frame 212 and the fixed frame 1, and the upper sliding rod 211 passes through the upper reset spring 321. One end of the upper reset spring 321 is fixedly connected with the hot cutting frame 212, and the other end of the upper reset spring 321 is fixedly connected with the fixed frame 1. The eccentric driving wheel 322 is coaxially fixedly arranged at one end of the main driving shaft 311. One end of the driving connecting rod 323 is eccentrically rotatably connected to the side of the eccentric driving wheel 322 away from the main driving shaft 311, and the other end of the driving connecting rod 323 is rotatably connected to the upper sliding rod 211.

[0043] With reference to Figure 9 When the main driving shaft 311 rotates, the eccentric driving wheel 322 rotates, thereby driving the driving connecting rod 323 to swing, and driving the upper sliding rod 211 to slide towards or away from the fixed frame 1, thereby driving the hot cutting frame 212 to slide towards or away from the abutting seat 222. Meanwhile, the arrangement of the upper reset spring 321 enables the hot cutting frame 212 to be more quickly reset away from the abutting seat 222.

One end of the lower reset spring 331 is fixedly connected with the connecting rod 223, and the other end of the lower reset spring 331 is fixedly connected with the fixed frame 1. The abutting wheel 332 is coaxially fixedly arranged on the connecting rod 223. The driving cam 333 is coaxially fixedly arranged on the main driving shaft 311. The abutting wheel 332 abuts against the driving cam 333.

[0045] With reference to Figure 9 When the main driving shaft 311 rotates, the driving cam 333 rotates, thereby driving the connecting rod 223 to move towards or away from the fixed frame 1 through the abutting wheel 332, thereby driving the two lower sliding rods 221 to slide towards or away from the fixed frame 1, thereby driving the abutting seat 222 to slide towards or away from the hot cutting frame 212, thereby completing the driving of the abutting seat 222. Meanwhile, the arrangement of the lower reset spring 331 enables the abutting wheel 332 to always abut against the driving cam 333, thereby making the driving of the abutting seat 222 by the driving cam 333 more stable.

[0046] The implementation principle of the cutting device of the full-automatic bagging machine is as follows: when the hot cutting and sealing bag mechanism needs to cut and seal the double-layer film bag in which the product has been placed, the driving assembly 3 is driven, the hot cutting frame 212 and the abutting seat 222 slide towards each other at the same time, until the abutting block 214 and the top of the double-layer film bag abut and cooperate, and the abutting seat 222 and the bottom of the double-layer film bag abut and cooperate, so that the double-layer film bag is abutted on both sides at the same time, then the abutting block 214 is stationary, the hot cutter 217 moves with the hot cutting frame 212 towards the double-layer film bag, until the hot cutter 217 completes the hot cutting and sealing of the double-layer film bag, when the hot cutting and sealing bag mechanism cuts and seals the bag, the abutting block 214 and the abutting seat 222 abut the double-layer film bag on both sides at the same time, so that the pressure on both sides of the double-layer film bag is uniform, thereby reducing the air bubbles at the hot cutting and sealing position of the double-layer film bag, thereby reducing the problems such as wrinkles or virtual sealing during the hot sealing of the double-layer film bag, thereby improving the yield of the double-layer film bag hot sealing, and improving the problem that the double-layer film bag is easily subjected to local stress concentration by abutting the double-layer film bag to the workbench through the abutting plate and then cutting the double-layer film bag through the hot cutter 217, thereby causing air bubbles at the hot cutting and sealing position of the double-layer film bag, and further causing problems such as wrinkles or virtual sealing during the hot sealing of the double-layer film bag, thereby causing the problem of poor yield of the double-layer film bag hot sealing.
