[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 6 As shown, in this embodiment, a pizza bag forming machine includes a bag cutting and flanging mechanism 2, a punching mechanism 4, an edge sealing mechanism 5, a cutting mechanism 7, and a frame 9;

[0039] The bag cutting and flanging mechanism 2 includes a cutting roller shaft 201, a flanging shaft 202, a feeding traction roller 203, and a feeding motor 204. The flanging shaft 202 is located above the cutting roller shaft 201. Both the flanging shaft 202 and the cutting roller shaft 201 are fixed on the frame 9. Two blades are provided in the middle of the cutting roller shaft 201. The drive end of the feeding motor 204 and the end of the feeding traction roller 203 are both equipped with first synchronous pulleys. The first synchronous pulleys are driven by a chain 205.

[0040] The punching mechanism 4 includes a punching cylinder 401 and a punching cutter 402, wherein the punching cutter 402 is fixed on the fixed end of the punching cylinder 401.

[0041] The edge sealing mechanism 5 includes a heat sealing cylinder 501, a V-shaped hot knife and a pressure plate 502. The pressure plate 502 is located above the heat sealing cylinder 501. Both the heat sealing cylinder 501 and the pressure plate 502 are fixed on the frame 9. The V-shaped hot knife is fixed on the drive end of the heat sealing cylinder 501.

[0042] The cutting mechanism 7 includes a cutting frame 701, a V-shaped waste cutter 702, a cutting cylinder 703, and a conveyor belt 704. The two ends of the cutting frame 701 are respectively installed on both sides of the conveyor belt 704. The cutting cylinder 703 is located above the conveyor belt 704. The fixed end of the cutting cylinder 703 is fixed on the cutting frame 701. The V-shaped waste cutter 702 is fixed on the driving end of the cutting cylinder 703.

[0043] The bag material first enters the bag cutting and flanging mechanism 2. When it passes the cutting roller 201, the blade cuts the entire bag material. As the bag material moves, the middle part is continuously cut open. The cut bag material passes through the two ends of the flanging shaft 202 and pushes open the cut part. Then, the feeding motor 204 controls the feeding traction roller 203 to pull and stretch the flanged bag material.

[0044] After exiting the bag cutting and flanging mechanism 2, the bag enters the punching mechanism 4, and the punching cylinders 401 on both sides control the punching cutter 402 to penetrate through both ends of the bag to form bag ears.

[0045] When the bag moves to the sealing mechanism 5, the heat sealing cylinder 501 controls the V-shaped hot knife to rise, pressing the bag onto the pressure plate 502 and performing heat sealing.

[0046] After the heat-sealing is completed, the bag enters the conveyor belt 704 for smooth transport. The cutting cylinder 703 controls the V-shaped waste cutter 702 to descend. The V-shaped waste cutter 702 cuts off the heat-sealed edge to remove the scraps. The conveyor belt 704 collects the complete pizza bag.

[0047] Specifically, the lower end of the bag cutting and flanging mechanism 2 is also fixed with a fixing rod 206. A swing frame 207 and a sensor are connected to the fixing rod 206. One end of the swing frame 207 is oscillatingly connected to the fixing rod 206. An auxiliary adjusting roller 208 is provided on the swing frame 207.

[0048] When the bag material passes through the sensor, if the subsequent conveying is too slow, the auxiliary adjusting roller 208 will tighten, and the conveying speed at the front end will increase. Conversely, if the subsequent conveying is too fast, the auxiliary adjusting roller 208 will loosen, and the conveying speed at the front end will decrease. Both are adjusted by the swing frame 207 swinging.

[0049] Furthermore, a waste strip recycling mechanism 3 is provided between the bag cutting and flanging mechanism 2 and the punching mechanism 4. The waste strip recycling mechanism 3 includes a waste strip recycling fixing rod 301 and a waste strip recycling roller 302. The waste strip recycling fixing rod 301 is fixed on the frame 9, and the waste strip recycling roller 302 is installed on the top of the waste strip recycling fixing rod 301.

[0050] After the bag raw material passes through the bag cutting and flanging mechanism 2, the waste strip in the middle is recycled around the waste strip recycling roller 302.

[0051] Specifically, the V-shaped hot knife includes a front hot knife 503, a rear hot knife 504, and a V-shaped knife holder 505. The angle between the front hot knife 503 and the rear hot knife 504 is 90°. Both the front hot knife 503 and the rear hot knife 504 are fixed on the V-shaped knife holder 505. The driving end of the heat sealing cylinder 501 is connected to the lower surface of the V-shaped knife holder 505.

[0052] The front hot knife 503 and the rear hot knife 504 form an angle of 90° between the scraps of the two pizza bags, which facilitates the formation of right angles on the edges of the pizza bags.

[0053] The edge sealing mechanism 5 is also provided with an adjusting screw 506, and an adjusting nut 507 is threadedly connected to the adjusting screw 506. A hot knife mounting plate 508 is fixed on the adjusting nut 507, and the fixed end of the heat sealing cylinder 501 is fixed on the hot knife mounting plate 508.

[0054] The position of the heat-sealing cylinder 501 can be controlled by controlling the position of the hot knife mounting plate 508, thereby meeting the size requirements of pizza bags with different production needs. More importantly, the adjustment is controlled by the movement of the adjusting nut 507 along the adjusting screw 506, which has high precision.

[0055] A bag edge cutting mechanism 6 is also provided between the sealing mechanism 5 and the cutting mechanism 7. The bag edge cutting mechanism 6 includes a feeding roller 601, a cutter motor 602, a bag edge cutter 603, and an adjusting cutter frame 604. A guide roller shaft 605 is provided on the adjusting cutter frame 604. The guide roller shaft 605 moves vertically on the adjusting cutter frame 604. The cutter motor 602 is located at the lower end of the frame 9. The drive end of the cutter motor 602 is connected to the feeding roller 601. The bag edge cutter 603 is located at the rear end of the bag edge cutting mechanism 6.

[0056] The cutting motor 602 controls the rotation of the feeding roller 601, which pushes the sealed pizza bag forward. The bag edge cutter 603 cuts the two pizza bags in the middle, making the pizza bags into independent units. The length of the pizza bag is controlled by the guide roller shaft 605 on the adjusting cutter 604.

[0057] More specifically, the front end of the frame 9 is provided with a plastic bag feeding mechanism 1, which includes a feeding frame 101 and a feeding roller shaft 102. The front end of the feeding frame 101 is provided with a roll material clamp 103, and the end of the feeding roller shaft 102 is clamped in the roll material clamp 103.

[0058] The bag material is wound around the feeding roller 102 in units of rollers. Each time the material is fed, the new feeding roller 102 can be fastened to the roll clamp 103 for use.

[0059] More specifically, a plastic bag collecting mechanism 8 is provided at the end of the frame 9. The plastic bag collecting mechanism 8 includes a gripper 801, a clamping cylinder 802, and a hook 803. The hook 803 is hinged to the front end of the gripper 801, the fixed end of the clamping cylinder 802 is hinged to the rear end of the gripper 801, and the driving end of the clamping cylinder 802 is connected to the hook 803.

[0060] The conveyor belt 704 is provided with guide rails 804 on both sides, the bag receiving mechanism 8 is provided with a moving plate 805, the gripper 801 is fixed on the moving plate 805, and the moving plate 805 is provided with guide rollers 806 at both ends, and the guide rollers 806 are movable on the guide rails 804.

[0061] The pizza bags, after passing through the edge cutting mechanism 6, fall onto the cutting mechanism 7. When 50 or 100 pizza bags are stacked, the bag collecting mechanism 8 can move forward or backward under the interaction of the guide rail 804 and the guide roller 806. When the bag collecting mechanism 8 moves forward, the clamping cylinder 802 extends, forcing the hook 803 to rotate at a certain angle and clamp the stacked pizza bags together with the gripper 801. Then the bag collecting mechanism 8 pulls the stacked pizza bags backward together, and then the cutting mechanism 7 cuts the edge of the pizza bag that has been heat-sealed.

[0062] It should be stated that the above specific embodiments are merely preferred embodiments of the present invention and the technical principles applied thereto. Within the scope of the technology disclosed in the present invention, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of the present invention.
