Description

Technical Field

[0001] This utility model relates to the field of thousand-sheet folding packaging technology, specifically a thousand-sheet continuous folding packaging machine. Background Technology

[0002] In the automated production process of soy products, the continuous folding packaging machine for tofu skin and tofu sheets is mainly used to realize the automated packaging of soy products such as tofu skin and tofu sheets. When it is working, the equipment realizes the continuous production of tofu skin through automatic grabbing, folding and conveying processes. Compared with traditional manual production, it can greatly improve production efficiency. The hourly output of a single machine can reach 100-500 catties, which meets the needs of large-scale production.

[0003] Currently, existing continuous folding packaging machines for thousand sheets mainly use suction cup robotic arms to grasp and feed the thousand sheets to be folded. However, due to external environmental factors, the surface of the thousand sheets is prone to dryness. In subsequent continuous operations, this problem directly affects the stability of the suction cup robotic arms in grasping and feeding operations, increases the probability of grasping failure, and also easily leads to an increase in the breakage rate of the thousand sheets during grasping. Therefore, a continuous folding packaging machine for thousand sheets is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous folding packaging machine for thousands of sheets, so as to solve the problem mentioned in the background art that the existing continuous folding packaging machine for thousands of sheets will have unstable feeding and failure to grip due to lack of water on the surface of the sheets.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A continuous folding packaging machine for 1000 sheets includes a main control box. An auxiliary frame is fixedly connected to the top of the main control box. A movable plate covers the top guide rail of the auxiliary frame. Push rods are fixedly connected to the left and right sides of the bottom of the movable plate. The front ends of the push rods abut against side fasteners. A spray square tube is fixedly connected between the two side fasteners. A spray tee is fixedly installed at the top center of the spray square tube. A clean water conveying pipe is connected to the top inlet end of the spray tee. Diverter bends are connected to the left and right sides of the spray tee. A solenoid valve is fixedly installed at the front end of the spray tee. An atomizing nozzle is connected to the bottom of the spray square tube. Guide grooves are opened on opposite sides of the two auxiliary frames. A slider, fixedly connected to the side fastener, is slidably connected to the inner side of the guide groove. A guide rod is slidably connected to the middle of the slider, and a spring is sleeved on the outside of the guide rod.

[0007] Preferably, the movable block located at the bottom edge of the mobile flat panel is slidably connected to the guide rail located at the top of the auxiliary frame. A drag chain drive host is fixedly installed at the upper left position of the top surface of the control main box. A traction drag chain is located at the lower front end of the drag chain drive host. The traction drag chain is slidably connected to the top position of the control main box. The head end of the traction drag chain is fixedly connected to the movable block located at the bottom left edge of the mobile flat panel.

[0008] Preferably, a lifting suction cup robot is provided in the gap between the two push rods on the left and right sides and is fixedly connected to the upper end of the moving plate. There are two lifting suction cup robots in total. The lifting suction cup robots and the atomizing nozzle are arranged adjacent to each other in front and behind. A shelf is fixedly installed at the front end of the control box directly below the atomizing nozzle.

[0009] Preferably, a conveyor belt is provided at the rear top of the control box, and an electric telescopic rod is fixedly installed at the front of the conveyor belt at the top of the control box. A folding flip plate is provided adjacent to the side of the conveyor belt away from the middle of the control box, and there are two folding flip plates in total.

[0010] Preferably, the front and rear ends of the guide rod are fixedly connected to the inner side of the guide groove, the front and rear ends of the spring are fixedly connected to the inner side of the guide groove and one end of the slider, one side of the side buckle plate and one side of the auxiliary frame are tightly fitted together, the liquid inlet end of the spray square tube and the liquid outlet end of the diversion bend are connected, and two sets of atomizing nozzles are provided.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, the push rod, side buckle plate, spray square tube, spray tee, clean water conveying pipe, solenoid valve, diversion bend, atomizing nozzle, guide groove, slider, guide rod, and spring facilitate the continuous folding and packaging machine for thousand sheets. Before the lifting suction cup robot mounted on the moving plate grasps and feeds the thousand sheets to be folded, the machine, with the auxiliary connection of the auxiliary frame, utilizes the push rod, side buckle plate, spray square tube, spray tee, clean water conveying pipe, solenoid valve, diversion bend, and atomizing nozzle. The water replenishment and humidification structure, composed of guide channels, sliders, guide rods, and springs, pre-hydrates and humidifies the tofu sheets placed on the shelf, ensuring that the surface of the tofu sheets remains moist. This facilitates the subsequent precise adsorption of the lifting suction cup robot, reduces the impact of external factors on the entire gripping and feeding process, lowers the probability of gripping failure, and reduces the breakage rate of the tofu sheets during gripping and feeding. At the same time, the inherent elastic stretching effect of the water replenishment and humidification structure also ensures that it does not interfere with the normal gripping operation of the lifting suction cup robot.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A continuous folding packaging machine for 1000 sheets includes a main control box 1. An auxiliary frame 2 is fixedly connected to the top of the main control box 1. A movable plate 3 covers the top guide rail of the auxiliary frame 2. Push rods 4 are fixedly connected to the left and right sides of the bottom of the movable plate 3. The front ends of the push rods 4 abut against side fasteners 5 that are slidably connected to the auxiliary frame 2. A spray square tube 6 is fixedly connected between the two side fasteners 5. A spray tee 7 is fixedly installed at the top center of the spray square tube 6. The top inlet is connected to a clean water delivery pipe 8. Both sides of the spray tee 7 are connected to diversion bends 10. A solenoid valve 9 is fixedly installed at the front end of the spray tee 7. The bottom of the spray square tube 6 is connected to an atomizing nozzle 11. The two auxiliary uprights 2 on opposite sides are provided with guide grooves 12. The inner side of the guide groove 12 is slidably connected to a slider 13 that is fixedly connected to the side buckle plate 5. The middle position of the slider 13 is slidably connected to a guide rod 14. A spring 15 is sleeved on the outside of the guide rod 14.

[0021] like Figure 1 and Figure 4 As shown, a movable block located at the bottom edge of the mobile tablet 3 is slidably connected to a guide rail located at the top of the auxiliary frame 2. A drag chain drive host 18 is fixedly installed on the upper left side of the top surface of the control main box 1. A traction drag chain 17 is located at the lower front end of the drag chain drive host 18. The traction drag chain 17 is slidably connected to the top of the control main box 1. The head end of the traction drag chain 17 is fixedly connected to the movable block located at the bottom left edge of the mobile tablet 3. Under the auxiliary traction of the drag chain drive host 18 and the traction drag chain 17, the mobile tablet 3 can move back and forth with the two lifting suction cup manipulators 16 on the left and right sides. The gap between the two push rods 4 is provided with the lifting suction cup manipulator 16, which is fixedly connected to the upper end of the mobile tablet 3. Two lifting suction cup robotic arms 16 are provided, and they are arranged adjacent to each other in front and behind the atomizing nozzles 11. A shelf 22 is fixedly installed at the front end of the control main box 1 directly below the atomizing nozzles 11. The corresponding vertical arrangement facilitates the packaging equipment to accurately replenish and humidify the tofu sheets through multiple atomizing nozzles 11. A conveyor belt 19 is located at the rear of the top of the control main box 1. An electric telescopic rod 21 is fixedly installed at the top of the control main box 1 in front of the conveyor belt 19. A folding flip plate 20 is located adjacent to the side of the conveyor belt 19 away from the middle of the control main box 1. There are two folding flip plates 20 in total. This structure allows the packaging equipment to perform efficient folding operations on two sets of tofu sheets at the same time during operation.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front and rear ends of the guide rod 14 are fixedly connected to the inner side of the guide groove 12, the front and rear ends of the spring 15 are fixedly connected to the inner side of the guide groove 12 and one end of the slider 13, one side of the side buckle plate 5 is tightly fitted to one side of the auxiliary frame 2, the liquid inlet end of the spray square tube 6 and the liquid outlet end of the diversion bend 10 are connected, and there are two sets of atomizing nozzles 11. After the spring 15 is deformed under pressure, it will generate rebound potential energy so that after the lifting suction cup robot 16 completes the gripping work, the water replenishment and humidification structure can use the rebound potential energy to achieve rapid reset work.

[0023] Workflow: The electrical energy required for the packaging equipment in this utility model to start and run is all from an external power source. When the equipment starts and runs, the movable end of the electric telescopic rod 21 is in a state of transmission connection with the rotating shaft of the folding and turning plate 20. In the process of automatic production of bean products, this continuous folding packaging machine for tofu sheets is required. When processing the tofu sheets to be processed, first place the tofu sheets to be processed flat on the shelf 22. Under the connection of the control main box 1 and the auxiliary upright frame 2, first open the solenoid valve 9, and send the water into the spray tee 7 through the clean water well conveying pipe 8. Then, the liquid is fed into the spray square tube 6 through the diversion bend 10. With the upper and lower positions relatively opposite, the packaging equipment will use the mist brought out by multiple atomizing nozzles 11 to replenish and humidify the tofu sheets placed on the shelf 22. Subsequently, under the automatic control of the PLC main control system, the drag chain drive host 18 moves the drag chain 17 back and forth. Under the guidance of the top guide rail, the moving plate 3 moves back and forth with the two lifting suction cup robotic arms 16 on the left and right. The push rod 4 presses the side buckle plate 5 forward, and the slider 13 moves the side... The mounting plate 5, spray square pipe 6, spray tee 7, clean water delivery pipe 8, solenoid valve 9, diversion bend 10, and atomizing nozzle 11 move forward, compressing spring 15. Once the water replenishment and humidification assembly has moved into position, the lifting suction cup robot 16 moves to a position directly above the shelf 22 and then suctions and grabs the tofu sheets placed on the shelf 22. After the grabbing is completed, the moving plate 3, along with the traction chain 17, moves backward with the lifting suction cup robot 16, and the water replenishment and humidification assembly resets. Once the moving plate 3 has moved backward to a certain position, the lifting suction cup robot 16... 6. Place the tofu sheets to be processed onto the conveyor belt 19, with half of the sheets falling onto the folding and turning plate 20. At this time, start the electric telescopic rod 21 to drive the folding and turning plate 20. The folding and turning plate 20 will be rotated by the transmission force, thus completing the folding of the other half of the tofu sheets. Then, start the conveyor belt 19 to transport the folded tofu sheets backward so that they can be sent out of the entire packaging equipment. The single folding operation of the tofu sheets can be completed. The entire packaging equipment can then be used to continuously fold and package multiple tofu sheets by repeating the same operation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
