An intermediate plate 4-7 is fixedly connected to the top of the fixed frame 4-5, and the intermediate plate 4-7 is located in the shaping cover 4-6. A pressure rod 4-8 is fixedly connected to the side end surface of the intermediate plate 4-7. A pair of clamping wheels 4-9 are rotatably connected to both ends of the top of the fixed frame 4-5, and the clamping wheels 4-9 are driven to rotate by a motor. A heating pressing block 4-10 is provided on the fixed frame 4-5.

[0033] In this embodiment, in order to achieve the effect of sealing the edge after folding the paper bag in half, a shaping pre-sealing component 4 is designed. Two side frames 4-1 are arranged on the surface of the frame 1. A shaft roller 4-2 is installed between the side frames 4-1. The shaft roller 4-2 is used to insert the packaging bag roll. A plurality of tensioning rollers 4-3 are also arranged. One of the tensioning rollers 4-3 is driven to rotate by a motor. Both tensioning rollers 4-3 are provided with a transmission wheel 4-4 and are driven by a belt. The rotation of the two tensioning rollers 4-3 can be controlled by the motor. The tensioning rollers 4-3 are used to convey the packaging bag after bypassing the packaging bag. The surface of the frame 1 A fixing frame 4-5 is fixedly connected, and a shaping cover 4-6 and a middle plate 4-7 are arranged in the fixing frame 4-5. The packaging bag will be folded in half when passing through the shaping cover 4-6 and the middle plate 4-7, and a pressure rod 4-8 is also arranged. The pressure rod 4-8 is used to press in the middle of the packaging bag to assist in folding the packaging bag. Two pairs of pressing wheels 4-9 are arranged on the top of the fixing frame 4-5. The pressing wheels 4-9 are used to press the sealed edges and convey them. A heating pressing block 4-10 is arranged between the pressing wheels 4-9 on both sides, which is used to heat the packaging bag to seal the edges and continue to convey it backwards after sealing the edges.

[0034] Furthermore, the sealing and cutting assembly 5 includes a pair of conveying rollers 5-1, which are rotatably connected between the frame 1 and the outer cover 3. The conveying rollers 5-1 are driven to rotate by a motor. A transmission gear 5-2 is provided at the upper end of the conveying roller 5-1, and the transmission gears 5-2 are meshed with each other. A pair of clamping plates 5-3 are fixedly connected to the top of the outer cover 3, and a cutting opening 5-4 is provided on the side surface of the clamping plate 5-3. A telescopic cylinder 5-5 is provided on the inner surface of the outer cover 3, and a cutting tool holder 5-6 is connected to the output end of the telescopic cylinder 5-5. A rectangular opening 5-7 is provided on the side surface of the clamping plate 5-3. An edge sealing roller 5-8 is rotatably connected to the outer cover 3, and the edge sealing roller 5-8 is driven to rotate by a motor.

[0035] In this embodiment, two conveying rollers 5-1 are arranged in the outer cover 3, and a transmission gear 5-2 is arranged on the top of the conveying rollers 5-1. The transmission gears 5-2 are meshed with each other. The conveying rollers 5-1 are driven to rotate by a motor, and cooperate with the transmission gear 5-2 to make the two conveying rollers 5-1 rotate synchronously for conveying. Two clamping plates 5-3 are arranged in the outer cover 3. The clamping plates 5-3 further press and fit the package after edge sealing. A cutting opening 5-4 and a rectangular opening 5-7 are opened on the surface of the clamping plate 5-3 on one side. An edge sealing roller 5-8 driven to rotate by a motor is arranged in the outer cover 3. The edge sealing roller 5-8 is pressed and sealed at a certain distance during rotation. A telescopic cylinder 5-5 is arranged on the inner surface of the outer cover 3. A cutting tool holder 5-6 is arranged at the output end of the telescopic cylinder 5-5, which can enter the cutting opening 5-4 to cut the packaging bag after edge sealing.

[0036] Furthermore, the edge-sealing rollers 5-8 are of a self-heating structure.

[0037] In this embodiment, the self-heating structure is used in conjunction with the protrusions on the surface to perform edge sealing at intervals according to the size of the packaging bag.

[0038] Furthermore, the top of the middle plate 4-7 is a V-shaped structure, and the clamping wheel 4-9 matches the shape of the middle plate 4-7.

[0039] In this embodiment, the V-shaped structure facilitates fitting the edges of the packaging bag, and the edge sealing can be stably performed in cooperation with the clamping wheels 4-9.

[0040] Furthermore, the cross section of the shaping cover 4-6 is a U-shaped structure, and the bottom of the middle plate 4-7 and the bottom of the shaping cover 4-6 are both arc-shaped structures.

[0041] In this embodiment, the U-shaped structure can prevent the packaging bag from getting stuck due to the folding angle being too large when the packaging bag is folded in half.

[0042] When packaging is required, the packaging bag roll is installed on the shaft roller 4-2, pulled out and passed around the tensioning roller 4-3 in turn, and after being stretched to the bottom, it is inserted between the shaping cover 4-6 and the middle plate 4-7 at the bottom of the pressure rod 4-8, and the folded edge is located on the top of the middle plate 4-7. It is pressed by the clamping wheel 4-9 and continued to be pulled through the conveying roller 5-1, and then passed through the clamping plates 5-3. Then the processing is started. The moving packaging bag is first single-sidedly sealed by the heating pressing block 4-10 on the top of the fixed frame 4-5. When it is conveyed to the clamping plates 5-3, the edge sealing roller 5-8 rotates at a constant speed to seal the packaging bag at intervals. Finally, it is cut by the cutting knife holder 5-6 and falls onto the finished product conveyor belt 2 for transportation. It can be single-sidedly sealed by the edge sealing roller 5-8 and can be switched at will.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
