When the hot cutting bag sealing mechanism performs hot cutting and bag sealing, the driving cylinder drives, and the piston rod of the driving cylinder drives the hot cutting component to move toward the direction close to the double-layer film until the abutment plate presses the double-layer film against the workbench, and then the abutment plate remains stationary and slides toward the direction close to the heat insulation plate relative to the heat insulation plate, and the hot cutting knife continues to move toward the direction close to the double-layer film until it passes through the hot cutting groove to complete the hot cutting packaging of the double-layer film.

The two upper sliding rods 211 are slidably matched with the fixed frame 1 along the vertical direction. The two ends of the hot cutting frame 212 are fixedly connected to the two upper sliding rods 211, so that the hot cutting frame 212 is slidably matched with the fixed frame 1. The two shock-absorbing springs 213 are located at the top of the hot cutting frame 212. The two upper sliding rods 211 are respectively penetrated by the two shock-absorbing springs 213. One end of the two shock-absorbing springs 213 is fixedly connected to the hot cutting frame 212, and the other ends of the two shock-absorbing springs 213 are fixedly connected to the two upper sliding rods 211.

The contact block 214 is provided with a sliding groove that is penetrated, and the hot cutting frame 212 is fixedly provided with a limited axis 2121. The limited axis 2121 is passed through and slidably matched in the sliding groove, so that the first connecting portion 2141 and the second connecting portion 21 46 can be slidably matched with the hot cutting frame 212 in the vertical direction, and the first connecting part 2141 can also rotate around the limiting shaft 2121, and the second connecting part 2146 can also rotate around the limiting shaft 2121. A hot cutting groove 2144 is formed between the first abutting part 2142 and the second abutting part 2143. The hot cutting groove 2144 in the embodiment of the present application is a groove-shaped gap. Each abutting spring 215 is evenly distributed on both sides of the hot cutting frame 212, one end of each abutting spring 215 is fixedly connected to the hot cutting frame 212, and the other end of each abutting spring 215 is fixedly connected to the first connecting part 2141 or the second connecting part 2146.

[0036] Reference Figure 5 and Figure 6 The first abutting portion 2142 is provided with a first cooling channel 21421 which is arranged through it, and the second abutting portion 2143 is provided with a second cooling channel 21431 which is arranged through it. The first abutting portion 2142 is connected with a water inlet pipe 21422, and the second abutting portion 2143 is connected with a water outlet pipe 21432. A connecting pipe 2145 is connected between the first abutting portion 2142 and the second abutting portion 2143. The first cooling channel 21421 and the second cooling channel 21431 are connected through the connecting pipe 2145, thereby realizing water cooling of the first abutting portion 2142 and the second abutting portion 2143, so that the first abutting portion 2142 and the second abutting portion 2143 always maintain a suitable working temperature, thereby improving the service life of the first abutting portion 2142 and the second abutting portion 2143.

[0037] Reference Figure 3 and Figure 7 The first abutting portion 2142 is provided with a plurality of first cooling grooves 21423 which are arranged through the first abutting portion 2142, and each of the first cooling grooves 21423 is evenly distributed along the length direction of the first abutting portion 2142, and each of the first cooling grooves 21423 is connected to the hot cutting groove 2144; the second abutting portion 2143 is provided with a plurality of second cooling grooves 21433 which are arranged through the second abutting portion 2143, and each of the second cooling grooves 21433 is evenly distributed along the length direction of the second abutting portion 2143, and each of the second cooling grooves 21433 is connected to the hot cutting groove 2144.

[0038] Reference Figure 5The upper hot cutting component 21 further includes a heat insulating plate 216 and a hot cutting knife 217. The heat insulating plate 216 is fixedly arranged on the hot cutting frame 212, and the heat insulating plate 216 is arranged through the hot cutting groove 2144 and is located at the bottom of the first connecting portion 2141 and the second connecting portion 2146. The hot cutting knife 217 is arranged through the hot cutting groove 2144 and is fixedly arranged at the bottom of the hot cutting frame 212 together with the heat insulating plate 216, so that the heat of the hot cutting knife 217 is not easily transferred to the hot cutting frame 212, the first connecting portion 2141 and the second connecting portion 2146. In addition, the provision of the first cooling groove 21423 and the second cooling groove 21433 reduces the radiation area between the hot cutting knife 217 and the abutment block 214, thereby making it difficult for the heat of the hot cutting knife 217 to be transferred to the abutment block 214, thereby further making the abutment block 214 always maintain a suitable working temperature, so that when the abutment block 214 abuts against the double-layer film, it is not easy for the double-layer film to undergo plastic deformation due to overheating of the abutment block 214, thereby improving the heat sealing yield rate of the double-layer film.

[0039] Reference Figure 8 The hot cutting assembly 2 also includes a lower hot cutting component 22, which includes two lower sliding rods 221, abutment seats 222 and a connecting rod 223. The two sliding rods 221 are slidably matched with the fixed frame 1 along the vertical direction. The abutment seats 222 are located at the top of the two sliding rods 221, and the abutment seats 222 are fixedly connected to the two sliding rods 221, thereby realizing the sliding match between the abutment seats 222 and the fixed frame 1. The connecting rod 223 is located at the bottom of the two sliding rods, and the two ends of the connecting rod 223 are respectively fixedly connected to the two sliding rods 221.

[0040] Reference Figure 8 A knife pad 2221 is fixedly provided on the top of the abutment seat 222. In the embodiment of the present application, the knife pad 2221 has heat-resistant performance. When the abutment seat 222 abuts and cooperates with one side of the double-layer film, the knife pad 2221 abuts and cooperates with the double-layer film, so that when the double-layer film is hot-cut and sealed, it is not easy for the double-layer film to undergo plastic deformation due to overheating of the knife pad 2221, thereby improving the heat-sealing yield rate of the double-layer film.

[0041] Reference Fig. 9 The driving assembly 3 includes a main driving component 31, which includes a main driving shaft 311, a driving motor 312, a main driving wheel 313, a slave driving wheel 314 and a driving belt 315. The main driving shaft 311 is rotatably arranged on the fixed frame 1, the driving motor 312 is arranged on the fixed frame 1, the main driving wheel 313 is coaxially fixedly arranged on the output shaft of the driving motor 312, the slave driving wheel 314 is coaxially fixedly arranged on the main driving shaft 311, and the driving belt 315 is wound around the outer circumference of the main driving wheel 313 and the slave driving wheel 314. The driving motor 312 drives the main driving wheel 313 to rotate through the driving belt 315, thereby driving the slave driving wheel 314 to rotate, thereby driving the main driving shaft 311 to rotate.

The upper driving component 32 includes an upper return spring 321, an eccentric driving wheel 322 and a driving connecting rod 323. The upper return spring 321 is located between the hot cutting frame 212 and the fixed frame 1, and the upper sliding rod 211 is penetrated by the upper return spring 321. One end of the upper return spring 321 is fixedly connected to the hot cutting frame 212, and the other end of the upper return spring 321 is fixedly connected to the fixed frame 1. The eccentric driving wheel 322 is coaxially fixedly arranged at one end of the main driving shaft 311, and one end of the driving connecting rod 323 is eccentrically connected to the eccentric driving wheel 322 away from the main driving shaft 311. The other end of the driving connecting rod 323 is connected to the upper sliding rod 211.

[0043] Reference Fig. 9 When the main driving shaft 311 rotates, the eccentric driving wheel 322 rotates, thereby driving the driving connecting rod 323 to swing, thereby driving the upper sliding rod 211 to slide toward or away from the fixed frame 1, thereby driving the hot cutting frame 212 to slide toward or away from the abutment seat 222. At the same time, the setting of the upper reset spring 321 allows the hot cutting frame 212 to reset more quickly in the direction away from the abutment seat 222.

The abutment wheel 332 is coaxially fixed on the connecting rod 223, and the driving cam 333 is coaxially fixed on the main driving shaft 311. The abutment wheel 332 abuts and cooperates with the driving cam 333.

[0045] Reference Fig. 9 When the main driving shaft 311 rotates, the driving cam 333 rotates, thereby pushing the connecting rod 223 to move toward or away from the fixing frame 1 through the abutment wheel 332, thereby driving the two lower sliding rods 221 to slide toward or away from the fixing frame 1, thereby driving the abutment seat 222 to slide toward or away from the hot cutting frame 212, thereby completing the driving of the abutment seat 222. At the same time, the setting of the lower return spring 331 enables the abutment wheel 332 to always maintain abutment and cooperation with the driving cam 333, thereby making the driving stability of the driving cam 333 on the abutment seat 222 better.

[0046] The implementation principle of the cutting device of a fully automatic bagging machine in the embodiment of the present application is as follows: when the hot-cut bag sealing mechanism needs to hot-cut and seal the double-layer film on which the product has been placed, the driving component 3 is driven, and the hot-cutting frame 212 and the abutting seat 222 slide towards each other at the same time until the abutting block 214 abuts and cooperates with the top of the double-layer film, and the abutting seat 222 abuts and cooperates with the lower part of the double-layer film, thereby simultaneously pressing both sides of the double-layer film, and then the abutting block 214 is stationary, and the hot-cutting knife 217 moves with the hot-cutting frame 212 towards the double-layer film until the hot-cutting knife 217 completes the hot-cutting and sealing of the double-layer film. When the hot-cutting and sealing mechanism is hot-cutting and sealing, the abutting block 214 is in contact with the top of the double-layer film, and the abutting seat 222 abuts and cooperates with the lower part of the double-layer film. 4 and the abutment seat 222 abut both sides of the double-layer envelope at the same time, so that the pressure on both sides of the double-layer envelope is uniform, thereby reducing bubbles at the hot-cutting and sealing position of the double-layer envelope, thereby reducing the occurrence of problems such as wrinkles or virtual sealing when the double-layer envelope is heat-sealed, thereby improving the yield rate of the heat-sealing of the double-layer envelope, improving the double-layer envelope The film is pressed tightly against the workbench by the abutment plate and then hot-cut by the hot cutting knife 217, which easily causes local stress concentration on the double-layer envelope, and then bubbles are easily generated at the hot-cutting and sealing position of the double-layer envelope, which in turn causes problems such as wrinkles or virtual sealing when the double-layer envelope is heat-sealed, resulting in a poor heat-sealing yield rate of the double-layer envelope.
