[0007] According to the above technical solution, the supply device also includes a ratchet, a pawl and an output plate. The ratchet is fixedly mounted on the circumferential surface of the driving rod, the pawl is slidably mounted on the surface of the fixed frame, and the output plate is fixedly mounted on the rear side of the collecting frame. When the driving rod rotates counterclockwise, the ratchet is driven to rotate. At this time, the ratchet will contact the inclined surface of the pawl, causing the pawl to move outward while compressing spring No. 1.

[0008] According to the above technical solution, the side of the pawl close to the ratchet is set as an inclined surface, and a No. 1 spring is arranged between the pawl and the fixed frame. The pawl is reset by the arranged No. 1 spring. When the driving rod rotates counterclockwise, it will contact the non-inclined surface of the pawl.

[0011] According to the above technical solution, the input device includes an L-shaped frame, a baffle and a buffer button. The L-shaped frame is slidably installed on the fixed end of the telescopic plate, the baffle is fixedly installed on the movable end of the telescopic plate, and the buffer button is rotatably installed on the movable end of the telescopic plate.

The movement of the limit plate will move the vacuum bag that exceeds the range of the stepping frame.

[0014] The present invention provides an automatic finishing device for a PEPA heat shrink vacuum bag packaging machine. It has the following beneficial effects: (1) The invention, through the setting of the supply device, when the bundled vacuum bag is input into the first groove of the collection rack, the vacuum bag is moved from the first groove to the second groove through the servo motor, the connecting plate and the stepping frame, and the vacuum bag is supplied step by step until it is delivered to the output plate for output. The stepping supply can accurately control the delivery position and spacing of the vacuum bag, ensuring that each vacuum bag can accurately reach the specified position, facilitating the subsequent vacuum packaging and other processes to be carried out accurately, reducing the operation delay caused by position deviation, and improving the overall production rhythm. The driving rod, round rod, collection rack, connecting rod, sliding plate, brake frame and stepping frame enable the vacuum bags of different lengths to be adjusted in time, and the ratchet and ratchet wheel are used to prevent the adjustment from losing the effect due to operation error when the spacing of the collection rack is adjusted.

[0015] (2) In the present invention, through the setting of the input device, the waiting area of ​​the vacuum bag is located at the movable end of the telescopic plate, and its movement is restricted by the barrier plate. The movable ends of the telescopic plates on both sides are driven to move inward by adjusting the spacing of the collection rack to match the spacing of the collection rack. The vacuum bag is released and falls through the stepping rack, driving button, brake button and barrier plate. When the vacuum bag falls, it will contact the buffer button, and the falling of the vacuum bag will be buffered by the buffer button.

[0016] (3) The invention, through the setting of the limiting device, uses the brake button and the rotating rod to move the card plate downward. The downward movement of the card plate will block the subsequent vacuum bags, preventing multiple vacuum bags from falling at the same time due to the failure of the blocking plate to reset in time, causing the exit to be blocked. When the vacuum bag is in the first groove, the vacuum bag that exceeds the range of the stepping frame is moved by rotating the motor, reciprocating screw and limit plate, preventing the vacuum bag from deviating during the stepping conveying process and falling out of the equipment, causing unnecessary losses.

The ratchet 13 is fixedly mounted on the circumferential surface of the driving rod 2, the pawl 14 is slidably mounted on the surface of the fixed frame 1, and the output plate 15 is fixedly mounted on the rear side of the collecting frame 8 to prevent the adjustment from losing its effect due to operational errors when the spacing of the collecting frame 8 is adjusted.

[0021] The side of the pawl 14 close to the ratchet wheel 13 is set as an inclined surface, and a spring No. 1 is arranged between the pawl 14 and the fixing frame 1, and the pawl 14 is driven to reset by the arranged spring No. 1.

[0022] When the present embodiment is working, when the bundled vacuum bag is input to the first groove of the collecting rack 8, the output end of the servo motor 9 drives the connecting plate 6 to rotate, and the rotation of the connecting plate 6 causes the stepping rack 7 to rotate, and the rotation of the stepping rack 7 causes the vacuum bag to be moved from the first groove to the second groove, and the vacuum bag is supplied step by step in this way until it is delivered to the output plate 15 for output.

[0026] The limiting device includes a card plate 30 and a rotating rod 31. The card plate 30 is slidably installed on the fixed end of the telescopic plate 20. One side of the rotating rod 31 is fixedly installed on the left side of the brake button 23, and the other side of the rotating rod 31 is fixedly installed on the left side of the card plate 30 to prevent multiple vacuum bags from falling at the same time due to the failure of the blocking plate 22 to reset in time, causing the exit to be blocked.

[0027] The limiting device also includes a circular groove frame 32, a rotating motor 33, a reciprocating screw rod 34 and a limit plate 35.
