Description

Technical Field

[0001] This utility model relates to the field of plastic bags, and in particular to a plastic bag making machine. Background Technology

[0002] In the field of plastic product manufacturing, plastic bags are a widely used packaging product. The performance and function of the production equipment directly affect production efficiency, product quality, and market adaptability. As the market demand for plastic bags continues to change and upgrade, the limitations of traditional plastic bag making machines in terms of function and performance are becoming increasingly prominent.

[0003] Currently, most plastic bag making machines require cutting after sealing the plastic bags. However, the cutting methods are relatively simple, mainly involving cutting individual plastic bags completely. This fails to meet the market demand for plastic bags with perforated lines. Perforated lines allow consumers to easily tear the plastic bags, improving convenience. Traditional bag making machines lack the ability to precisely cut through perforated lines between plastic bags, thus failing to meet this market demand. Even when some machines attempt similar cutting operations, problems such as low cutting accuracy, discontinuous lines, and inconsistent depth exist. These problems not only affect the aesthetic appearance of the plastic bags but may also lead to... In actual tearing processes, uneven tearing and difficulty in tearing occur, reducing the user experience. Secondly, in the winding stage, traditional bag making machines usually only perform simple winding operations on individual plastic bags after sealing and cutting, lacking special consideration for winding plastic bags with dotted lines. Due to the presence of dotted lines, plastic bags are prone to misalignment, wrinkles, or even breakage during winding, affecting winding quality and efficiency. The various stages (sealing, cutting, and winding) of traditional plastic bag making machines are relatively independent, requiring multiple drive components to cooperate, thus increasing production costs. To solve the above problems, we propose a new plastic bag making machine. Utility Model Content

[0004] The main objective of this invention is to provide a plastic bag making machine that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic bag making machine includes a support table, a conveyor belt sleeved on the outer side of the support table, a gantry frame installed at the upper end of the support table, a buffer groove at the lower end of the gantry frame, a movable plate slidably connected to the inner side of the buffer groove, a sealing heating block fixedly installed at the lower end of the movable plate, a cutting head fixedly connected to the lower end of the movable plate on one side of the sealing heating block, and a winding assembly at the rear end of the support table.

[0007] Preferably, a drive motor is provided on one side of the support table, the drive motor is located at the front end of the winding assembly, the output end of the drive motor is fixedly connected to a drive roller, the drive roller is located on the inner side of the rear end of the conveyor belt, and the drive roller is rotatably connected to the support table, and a driven roller is sleeved on the inner side of the front end of the conveyor belt, the driven roller is rotatably connected to the support table.

[0008] Preferably, two cylinders are fixedly installed at the upper end of the gantry frame, and the output ends of the two cylinders are both fixedly connected to the upper end of the moving plate.

[0009] Preferably, the winding assembly includes a winding roller, one end of which is rotatably connected to a mounting frame. The mounting frame is located behind the drive motor. The lower end of the mounting frame has a mounting groove. A driven wheel is fixedly connected to the outside of the winding roller on the inner side of the mounting groove. A belt is sleeved on the outside of the driven wheel. A drive wheel is fixedly connected to the outside of the drive roller. The drive wheel is connected to the driven wheel via a belt.

[0010] Preferably, a lifting leg is provided at the lower end of the take-up roller on the side away from the driven wheel, and a main support leg is sleeved on the outer side of the lower end of the lifting leg.

[0011] Preferably, a rack is fixedly connected to the inner side of the lifting leg, a gear meshes with the outer side of the rack, a rotating shaft is fixedly connected to the inner side of the gear, the rotating shaft is rotatably connected to the main support leg, and a handwheel is fixedly connected to one side of the rotating shaft, the handwheel being located on the outer side of the main support leg.

[0012] Preferably, a mounting base is fixedly connected to one side of the drive motor, and the mounting base is fixedly mounted on the support table.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This plastic bag making machine uses two cylinders that are started simultaneously. The output ends of the two cylinders work together to move the moving plate downwards. At this time, the plastic bag tube can be easily sealed by the sealing heating block and the cutting head. At the same time, the sealing strip is cut on one side, causing a row of through-cut dotted lines to be formed on the plastic bag tube.

[0015] This plastic bag making machine uses a drive motor to rotate the active roller. With the guidance of the driven roller, the conveyor belt can easily move the plastic bag cylinder backward. At the same time, the active roller rotates, which also drives the active wheel to rotate. With the help of the belt, the driven wheel can easily drive the winding roller to wind up the plastic bag.

[0016] This type of plastic bag making machine, when the plastic bag on the take-up roller is rolled to a certain size, turns the hand dial. The turn of the hand dial will drive the rotating shaft to rotate, and the rotating shaft will drive the gear to rotate. At this time, through the meshing connection of the rack and pinion, the lifting leg can be easily slid into the inner cavity of the main support leg, releasing the support on the take-up roller, and thus the rolled-up plastic bag can be easily unwound.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] In this embodiment, a drive motor 3 is provided on one side of the support table 1. The drive motor 3 is located at the front end of the winding assembly. The output end of the drive motor 3 is fixedly connected to an active roller 5. The active roller 5 is located on the inner side of the rear end of the conveyor belt 2 and is rotatably connected to the support table 1. A driven roller 6 is sleeved on the inner side of the front end of the conveyor belt 2 and is rotatably connected to the support table 1.

[0026] Specifically, by starting the drive motor 3, the output end of the drive motor 3 will drive the active roller 5 to rotate. At this time, with the guidance of the driven roller 6, the conveyor belt 2 can easily move the plastic bag cylinder backward.

[0027] In this embodiment, two cylinders 13 are fixedly installed on the upper end of the gantry frame 12, and the output ends of the two cylinders 13 are both fixedly connected to the upper end of the moving plate 15.

[0028] Specifically, when two cylinders 13 are activated simultaneously, the output ends of the two cylinders 13 will jointly drive the moving plate 15 to move downward. At this time, the plastic bag tube can be easily sealed by the sealing heating block 16 and the cutting head 17, and at the same time, it is cut on one side of the sealing strip, so that a row of through-cut dotted lines is formed on the plastic bag tube.

[0029] In this embodiment, the winding assembly includes a winding roller 11. A mounting frame 24 is rotatably connected to the outer side of one end of the winding roller 11. The mounting frame 24 is located behind the drive motor 3. A mounting groove 25 is provided at the lower end of the mounting frame 24. A driven wheel 10 is fixedly connected to the outer side of the winding roller 11 on the inner side of the mounting groove 25. A belt 9 is sleeved on the outer side of the driven wheel 10. A drive wheel 8 is fixedly connected to the outer side of the drive roller 5. The drive wheel 8 is connected to the driven wheel 10 through the belt 9.

[0030] Specifically, while the drive roller 5 is rotating, it will also drive the drive wheel 8 to rotate. At this time, with the cooperation of the belt 9, the driven wheel 10 can easily drive the take-up roller 11 to take up the plastic bag.

[0031] In this embodiment, a lifting leg 19 is provided at the lower end of the take-up roller 11 on the side away from the driven wheel 10. A main support leg 18 is sleeved on the outer side of the lower end of the lifting leg 19. A rack 20 is fixedly connected to the inner side of the lifting leg 19. A gear 21 meshes with the outer side of the rack 20. A rotating shaft 22 is fixedly connected to the inner side of the gear 21. The rotating shaft 22 is rotatably connected to the main support leg 18. A handwheel 23 is fixedly connected to one side of the rotating shaft 22. The handwheel 23 is located on the outer side of the main support leg 18.

[0032] Specifically, when the plastic bag on the take-up roller 11 is rolled to a certain size, the handwheel 23 is turned. The rotation of the handwheel 23 will drive the rotating shaft 22 to rotate, and the rotation of the rotating shaft 22 will drive the gear 21 to rotate. At this time, through the meshing connection of the rack 20, the lifting leg 19 can be easily slid into the inner cavity of the main support leg 18, releasing the support on the take-up roller 11, and thus the rolled-up plastic bag can be easily unrolled.

[0033] In this embodiment, a mounting base 4 is fixedly connected to one side of the drive motor 3, and the mounting base 4 is fixedly installed on the support table 1.

[0034] Specifically, the design of the mounting base 4 can improve the stability of the drive motor 3 during operation. After the drive motor 3 has been working for a period of time, the plastic bag tube will move backward a certain distance. At this time, the drive motor 3 will stop rotating, and the two cylinders 13 will start again to seal and cut the plastic bag tube. Similarly, through the intermittent cooperation between the cylinders 13 and the drive motor 3, the plastic bag tube can be produced into finished plastic bags.

[0035] It should be noted that this utility model is a plastic bag making machine. The user fixes one end of the plastic bag tube to be cut and sealed to the outside of the winding roller 11, while placing the other end on the upper end of the conveyor belt 2. At this time, two cylinders 13 are started simultaneously. The output ends of the two cylinders 13 will jointly drive the moving plate 15 to move downward. At this time, through the sealing heating block 16 and the cutting head 17, the plastic bag tube can be easily sealed, and at the same time, a cut is made on one side of the sealing strip, so that a row of through-cut dotted lines is formed on the plastic bag tube. After the plastic bag tube is sealed and cut, the cylinders 13 will start in reverse. The output end of the cylinders 13 will drive the moving plate 15 to slide into the inner cavity of the buffer groove 14. At this time, the drive motor 3 will start, and the output end of the drive motor 3 will drive the drive roller 5 to rotate. At this time, with the guidance of the driven roller 6, the conveyor belt 2 can easily move the plastic bag tube backward, and the drive roller... While rotating, the drive wheel 8 will also rotate. With the help of the belt 9, the driven wheel 10 can easily drive the take-up roller 11 to take up the plastic bag. When the plastic bag tube moves backward a certain distance, the drive motor 3 will stop rotating. At this time, the two cylinders 13 will start again to seal and cut the plastic bag tube. Similarly, through the intermittent cooperation between the cylinders 13 and the drive motor 3, the plastic bag tube can be produced into a finished plastic bag. When the plastic bag on the take-up roller 11 is rolled to a certain size, the handwheel 23 is turned. The rotation of the handwheel 23 will drive the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 will drive the gear 21 to rotate. At this time, through the meshing connection of the rack 20, the lifting leg 19 can easily slide into the inner cavity of the main support leg 18, releasing the support of the take-up roller 11, and thus the rolled-up plastic bag can be easily unrolled, which is quite practical.
