[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a bag making machine that is easy to unload, including a workbench 1, a cylinder 2 is fixedly installed on the top of the workbench 1, and the piston at the output end of the cylinder 2 is connected to a piston rod 3, and a cutting knife 4 is fixedly installed on the bottom of the piston rod 3, and a sealer 5 is fixedly installed on the bottom of the piston rod 3. When the cylinder 2 is started, the piston rod 3 can be driven to make the sealer 5 and the cutting knife 4 move up and down, so that the bag body can be sealed and cut. A motor 6 is fixedly installed on the back of the workbench 1, and a rotating shaft 7 is fixedly installed on the output end of the motor 6. A transmission wheel 8 is fixedly installed on the outer wall of the rotating shaft 7. The outer wall of the transmission wheel 8 is connected to the outer wall of another transmission wheel 8 by a conveyor belt 9, which can drive the transmission wheel 8 to rotate when the motor 6 is started, so that the conveyor belt 9 can rotate, so that the cut bags can be transported. An alignment mechanism 10 is provided on the right side of the workbench 1 to sort the bags.
[0024] Specifically, the alignment mechanism 10 includes: a U-shaped plate 101, a pull-out plate 102, a disc 103, a connecting rod 104, a slider 105, a U-shaped rod 106, a push rod 107, a push plate 108, a threaded rod 109, an extrusion plate 110, a guide rod 111, a positioning bolt 112, and a spring 113. The left side of the U-shaped plate 101 is fixedly installed on the right side of the workbench 1, the top of the U-shaped plate 101 is slidably installed with the pull-out plate 102, the front of the rotating shaft 7 is fixedly installed with the disc 103 and the connecting rod 104, the back of the connecting rod 104 is hinged at the eccentric position of the disc 103, the end of the connecting rod 104 away from the disc 103 is hinged with the slider 105, and the outer wall of the slider 105 is slidably installed on the In the slide groove of the U-shaped plate 101, a U-shaped rod 106 is fixedly installed at the bottom of the slider 105, which can drive the disc 103 to rotate when the rotating shaft 7 rotates, so that the connecting rod 104 can push the slider 105 to move. At the same time, the U-shaped rod 106 will drive the other slider 105 to move at the same time. A push rod 107 is hinged on the left side of the slider 105, and a push plate 108 is hinged on the end of the push rod 107 away from the slider 105. A threaded rod 109 is threadedly connected to the through hole of the push plate 108. There are two groups of push rods 107, push plates 108, and threaded rods 109, and they are symmetrical with the central symmetry axis of the front side of the U-shaped plate 101, and are symmetrically distributed on the front and back sides of the U-shaped plate 101. The two sides of the bag body can be slapped at the same time to align them. The outer wall of the threaded rod 109 is slidably installed at the through hole of the U-shaped plate 101. The left side of the threaded rod 109 is rotatably installed with an extrusion plate 110. When the slider 105 moves, it will push the push rod 107 to move, so that the push plate 108 moves toward the center of the U-shaped plate 101, and at the same time drive the threaded rod 109 to move. When the threaded rod 109 moves, it will drive the extrusion plate 110 to slap the bag body to align it. A guide rod 111 is fixedly installed on the right side of the extrusion plate 110, and the guide rod 111 is slidably installed on the U-shaped plate 1 01 and the through hole of the push plate 108, a positioning bolt 112 is slidably installed at the through hole of the U-shaped plate 101, and a spring 113 is fixedly installed on the right side of the U-shaped plate 101. By pulling out the positioning bolt 112, the spring 113 is stretched, which can make the positioning bolt 112 disengage from the hole of the pull-out plate 102, and the pull-out plate 102 can be easily pulled out. Conversely, when the positioning bolt 112 is inserted, the spring 113 will insert the positioning bolt 112 into the hole of the pull-out plate 102 to prevent it from falling off. The end of the spring 113 away from the U-shaped plate 101 is fixedly installed on the left side of the protrusion of the positioning bolt 112.
[0025] Working principle: By starting the cylinder 2, the piston rod 3 drives the cutting knife 4 and the sealer 5 to move up and down, the bag can be cut and sealed, and then by starting the motor 6, the shaft 7 drives the transmission wheel 8 to rotate, and the conveyor belt 9 rotates, so that the cut bag can be moved to the inside of the U-shaped plate 101 through the conveyor belt 9. At the same time, the shaft 7 will drive the disc 103 to rotate when it rotates. The disc 103 will then drive the connecting rod 104 to push the slider 105 to move. When the slider 105 moves, it will drive the U-shaped rod 106 to move, causing the other slider 105 to slide at the same time. Slider 1 When 05 moves, it will push the pushing rod 107, so that the pushing rod 107 pushes the pushing plate 108 to move, and the pushing plate 108 drives the threaded rod 109 to move the extrusion plate 110, so that the extrusion plates 110 on both sides can simultaneously beat and align the bag bodies, so that the bag bodies can be neatly placed inside the U-shaped plate 101, and then the positioning bolt 112 is pulled out. At this time, the spring 113 will be stretched and pulled out from the hole of the pull-out plate 102. After pulling out the pull-out plate 102, the collected bags can be placed, which is convenient for the operator to unload them and there is no need to re-arrange them.
[0026] When the width of the bag is relatively small, the threaded rod 109 can be rotated to rotate in the pushing plate 108, and the extrusion plate 110 will be pushed out at the same time. At this time, the guide rod 111 will also move. The guide rod 111 can prevent the extrusion plate 110 from rotating. In this way, the gap between the extrusion plate 110 and the pushing plate 108 can be enlarged and narrowed, so that bags of different sizes can be slapped and aligned, which increases the versatility of the equipment.
[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
