[0002] Plastic bags are bags made primarily of plastic and are commonly used in daily life to hold other items. Common materials for plastic bags include polypropylene, polyester, and nylon. They are widely used because of their light weight, large capacity, and ease of storage. In the processing and production of plastic bags, a multi-functional plastic bag forming machine is required.

[0003] Existing multi-functional plastic bag forming machines generally use heated cutting blades to cut plastic bags that have undergone heat sealing. While this ensures a smooth cut without burrs or rough edges, guaranteeing the appearance quality of the plastic bag, the blades tend to dull due to plastic adhesion after prolonged use. This results in the blades not being able to cut the plastic bag cleanly in subsequent uses, and the blades may squeeze and tear the plastic bag, leading to rough edges, jagged edges, or tears. Consequently, the cutting quality of the heated cutting blades is reduced, thus diminishing both the effectiveness and efficiency of the multi-functional plastic bag forming machine.

[0004] Therefore, a new type of multifunctional plastic bag forming machine is needed to solve the aforementioned technical problems. Utility Model Content

[0026] Please see Figures 1-6 This utility model provides a technical solution: a multifunctional plastic bag forming machine, including a workbench 1, a cutter assembly 2 installed on the workbench 1, and a processing mechanism 3 provided on the workbench 1;

[0027] The processing mechanism 3 includes a rectangular plate 301. A groove 302 is provided on the top of the rectangular plate 301. A slider 303 is slidably connected inside the groove 302. A round rod 304 is fixed on one side of the slider 303. A perforated block 305 is fixedly sleeved on the outer surface of one end of the round rod 304. An L-shaped block 306 is fixed on the top of the slider 303. An auxiliary block 307 is installed on the front surface of the L-shaped block 306. A housing 308 is fixed on the bottom of the auxiliary block 307. Mounting plates 309 are installed on both the front and rear surfaces of the auxiliary block 307.

[0028] like Figures 1-4 and Figure 6 As shown, the bottom of the inner walls of the two through holes of the workbench 1 are fixed to the bottom of the rectangular plate 301. The perforated block 305 is installed on the bottom of the inner wall of the slide 302 by screws, so that the slide 302 can provide an installation position for the perforated block 305.

[0029] like Figure 1 , Figures 3-6 As shown, the top of the slider 303 is on the same horizontal plane as the top of the rectangular plate 301, and the bottoms of the two mounting plates 309 are in contact with the top of the housing 308. Under the action of the housing 308, the scraped plastic can be collected.

[0030] like Figures 1-3 As shown, a conveying assembly 4 is fixed on the front surface of the workbench 1 near the bottom. A guide assembly 5 is installed on the front surface of the conveying assembly 4. Four rectangular slots 6 are provided at the bottom of the workbench 1, which facilitates the fixing of the U-shaped frame 7 to the workbench 1 with the cooperation of the rectangular slots 6, threaded holes 8 and hand-tightening bolts 9.

[0031] like Figure 1 and Figure 2As shown, the four rectangular slots 6 are divided into two groups. Each group of rectangular slots 6 has a U-shaped frame 7 that is movably connected between them. Each U-shaped frame 7 has four threaded holes 8 on one side. With the cooperation of the threaded holes 8, the worktable 1 and the hand-tightening bolts 9, the U-shaped frame 7 can be fixed between the interiors of the two rectangular slots 6.

[0032] like Figures 1-5 As shown, a driver 11 is installed on the side of the worktable 1 near the slider 303, and a controller 10 is installed on the side of the worktable 1 near the slider 303. Two hand-tightened bolts 9 are threaded through both sides of the worktable 1 to provide installation positions for the controller 10 and the driver 11 under the action of the worktable 1.

[0033] like Figures 1-3 As shown, the threaded ends of the four hand-tightening bolts 9 are respectively threaded into the four threaded holes 8. The driver 11 is electrically connected to the controller 10, and can start the conveyor assembly 4 with the cooperation of the controller 10, the worktable 1 and the driver 11.

[0034] The operating method and working principle of this device are as follows: When it is necessary to cut a plastic bag after heat sealing, first connect the controller 10 (PLC controller) to the external power supply. Then, place one end of the heat-sealed plastic bag inside the guide assembly 5 and make contact with the conveyor assembly 4. Next, using the cooperation of the controller 10 and the driver 11, directly start the conveyor assembly 4. At this time, the started conveyor assembly 4 will convey the plastic bag into the worktable 1 with the cooperation of the guide assembly 5. When one end of the plastic bag moves to the appropriate position, first use the cooperation of the controller 10 and the driver 11 to shut down the conveyor assembly 4. Then, use the controller 10 to start the cutter assembly 2. At this time, the started cutter assembly 2 will first cut the plastic bag in the appropriate position. Press and secure the plastic bag directly below it, then cut the plastic bag directly below it. When the cutter assembly 2 completes the cutting operation, first use the controller 10 to shut down the cutter assembly 2, then use the controller 10 and the driver 11 to start the conveyor assembly 4. The started conveyor assembly 4 will continue to convey the plastic bag. When the plastic bag moves to the appropriate position, simply follow the above operating steps. When it is necessary to process the plastic adhering to the hot cutting blade on the cutter assembly 2, first use the controller 10 to heat the hot cutting blade on the cutter assembly 2, then remove the screw on the perforated block 305. When the hot cutting blade on the cutter assembly 2 completes the heating operation, the plastic adhering to the hot cutting blade will be removed. The plastic softens again upon heating, and a force is applied to the perforated block 305, causing it to move away from the slider 303. This moving block 305, in conjunction with the round rod 304, drives the slider 303 to move inside the groove 302. The moving slider 303, in conjunction with the L-shaped block 306, drives the auxiliary block 307 to move. Simultaneously, the moving auxiliary block 307 moves the housing 308 and the two mounting plates 309 together. When the inner wall of the auxiliary block 307 contacts the cutting edge of the hot-cutting blade, one side of the continuing-moving auxiliary block 307 scrapes off the softened plastic adhering to the blade surface. Then, with the cooperation of the two mounting plates 309, the plastic is removed by the auxiliary block. The plastic scraped off by block 307 will fall into the interior of housing 308. When the auxiliary block 307 is not in contact with the hot cutting blade, the processing of the plastic adhering to the blade of the hot cutting blade on the cutting blade assembly 2 is completed. At the same time, the movement of the perforated block 305 should be stopped. When it is necessary to lower the height between the workbench 1 and the ground, first use a tool to lift the workbench 1 until the bottom of both U-shaped frames 7 are separated from the ground. Then remove all four hand-tightening bolts 9. At this time, the threaded ends of the four hand-tightening bolts 9 are separated from the corresponding threaded holes 8. Next, apply a force to each of the two U-shaped frames 7 to make both U-shaped frames 7 move vertically upward. When both U-shaped frames 7 have moved to the point where they can no longer move, stop the movement of the two U-shaped frames 7.Simultaneously, the tops of both U-shaped brackets 7 contact the top of the inner wall of their corresponding set of rectangular slots 6. Then, the four removed hand-tightening bolts 9 are returned to their original positions. At this point, the threaded ends of the four hand-tightening bolts 9 pass through the four threaded holes 8. Finally, the worktable 1 is lowered, thus completing the operation of reducing the height of the worktable 1.

[0035] Screws are common parts in real life.

[0036] The cutter assembly 2 includes a servo electric cylinder, a mounting base, a hot cutting blade, multiple T-shaped rods, a spring, and a pressing block. The servo electric cylinder is mounted on the top of the inner wall of the worktable 1, and the fixed end of the servo electric cylinder moves through the top of the inner wall of the worktable 1. Both the servo electric cylinder and the hot cutting blade are electrically connected to the controller 10. When the cutter assembly 2 is needed, the plastic bag to be cut can be fixed by the cooperation of the controller 10, the servo electric cylinder, the mounting base, the spring, the multiple T-shaped rods, and the pressing block. Then, the fixed plastic bag can be cut by the cooperation of the controller 10, the servo electric cylinder, the mounting base, and the hot cutting blade.

[0037] The conveying assembly 4 includes two motors, two drive rollers, and two mounting blocks. The guide assembly 5 includes two single-hole blocks, two connecting rods, two bolts, and two grooved blocks. When the conveying assembly 4 and guide assembly 5 are to be used, the two motors are first electrically connected to the driver 11. Then, the distance between the two grooved blocks is adjusted according to the size of the plastic bag. Then, the plastic bag is conveyed by the cooperation of the controller 10, the driver 11, and the two motors. At the same time, the plastic bag is guided by the cooperation of the two single-hole blocks, the two connecting rods, the two bolts, and the two grooved blocks to prevent the plastic bag from shifting during conveying.
