Description

[0001] This invention relates to an automatic packaging device for waterproof roll materials, belonging to the technical field of packaging. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project. The main products are asphalt waterproof membranes and polymer waterproof membranes.

[0003] After the waterproof membrane is produced, it needs to be wrapped with a packaging film before leaving the factory to prevent it from falling apart and to protect the surface of the waterproof membrane from damage. Existing waterproof membrane packaging equipment and the membrane production line are often located in different areas, and the two cannot be well connected. Furthermore, the wrapping of the waterproof membrane with the packaging film lacks a constant tension control system, resulting in uneven wrapping at the front and rear ends and poor packaging performance. Therefore, those skilled in the art have proposed an automatic waterproof membrane packaging device to solve the problems mentioned in the background art. Summary of the Invention

Detailed Implementation

[0018] like Figure 1 and Figure 2 As shown, an automatic packaging device for waterproof roll material includes an infeed conveyor belt 1 and an outfeed conveyor belt 2. Protective plates 16 are provided on both sides of the infeed conveyor belt 1 and the outfeed conveyor belt 2. The protective plates 16 are placed at an angle. A packaging structure is provided between the infeed conveyor belt 1 and the outfeed conveyor belt 2.

[0019] The packaging structure includes a workbench 3 with a notch in the middle. A rotary motor 5 is provided on one side of the workbench 3, and a set gear 6 is evenly distributed on the surface of the other side of the workbench 3. The rotary motor 5 is connected to a set gear 6 through a connecting rod. A ring 4 is provided between the set gears 6. The side of the ring 4 has a recess, and teeth are distributed in the recess on the side of the ring 4. The set gear 6 meshes with the teeth in the recess on the side of the ring 4.

[0020] The surface of the ring 4 is also fixedly connected to an unwinding block 8. The surface of the unwinding block 8 is provided with a groove. A sliding column 9 is provided in the groove on the surface of the unwinding block 8. An unwinding roller 10 is fixedly connected to the end of the sliding column 9. An air cylinder 11 is fixedly connected to the surface of the unwinding block 8. A piston 12 and a pressure sensor 13 are provided inside the air cylinder 11. The pressure sensor 13 is used to detect the air pressure inside the air cylinder 11. The piston 12 and the sliding column 9 are connected by a connecting rod.

[0021] One side of the air cylinder 11 is connected to an inflation pipe with an inflation valve 14, and the other side of the air cylinder 11 is connected to a deflation pipe with a deflation valve 15.

[0022] A reset platform 18 is provided below the transfer conveyor belt 2. A reset cylinder 17 is provided on one side of the reset platform 18, and a tension plate 19 is provided on the other side of the reset platform 18. A tension rod 7 is connected between the tension plate 19 and the reset cylinder 17. The tension rod 7 passes through the reset platform 18. Normally, the packaging film is placed on the surface of the unwinding roller 10, and the end of the packaging film is located on the surface of the tension rod 7. When the reset cylinder 17 retracts, it attaches the end of the packaging film to the side of the reset platform 18.

[0023] The waterproof membrane produced at the lower film stage is placed on the surface of the conveyor belt 1. When the waterproof membrane on the surface of the conveyor belt 1 passes through the notch in the workbench 3 and reaches below the unwinding roller 10, the rotary motor 5 starts to rotate, the locking gear 6 rotates, and the rotation of the locking gear 6 drives the ring 4 and the unwinding roller 10 to rotate. The packaging film on the surface of the unwinding roller 10 is wrapped around the surface of the waterproof membrane. The reset cylinder 17 extends to release the packaging film attached to the side of the reset table 18. Then the reset cylinder 17 retracts. When the waterproof membrane is completely away from below the unwinding roller 10, the reset cylinder 17 extends again and then retracts to pull the packaging film back onto the side of the reset table 18.

[0024] When the packaging film is wrapped around the surface of the waterproof membrane, if the tension of the packaging film between the waterproof membrane and the unwinding roller 10 increases, the piston 12 is pressed towards the waterproof membrane, increasing the gas pressure in the air cylinder 11 and the pressure sensor 13. This causes the vent valve 15 to open, reducing the gas pressure in the air cylinder 11. The unwinding roller 10 then moves towards the waterproof membrane, reducing the tension of the packaging film between the waterproof membrane and the unwinding roller 10. Conversely, if the pressure sensor 13 decreases, the inflation valve 14 opens, increasing the gas pressure in the air cylinder 11. The unwinding roller 10 then moves away from the waterproof membrane, increasing the tension of the packaging film between the waterproof membrane and the unwinding roller 10. By maintaining the pressure in the pressure sensor 13 at a set value, the tension of the packaging film between the waterproof membrane and the unwinding roller 10 is kept constant.

[0025] like Figure 3 As shown, the packaging structure also includes a chip U1, model STC12C5628AD. Pin 1 of chip U1 is connected to one end of resistor R1 and one end of capacitor C1. The other end of resistor R1 is connected to ground. The other end of capacitor C1 is connected to a +3.3V power supply. Pin 4 of chip U1 is connected to one end of crystal oscillator Y1 and one end of capacitor C2. Pin 5 of chip U1 is connected to the other end of crystal oscillator Y1 and one end of capacitor C3. The other ends of capacitor C2 and capacitor C3 are connected to ground. Pin 20 of chip U1 is connected to a +3.3V power supply. Pin 10 of chip U1 is connected to ground.

[0026] The packaging structure also includes a chip U2. Pins 1 and 8 of chip U2 are connected to a +3.3V power supply, pins 2, 4 and 7 of chip U2 are connected to a ground wire, pin 3 of chip U2 is connected to a current signal AI1, which comes from the signal output of the pressure sensor, pin 5 of chip U2 is connected to pin 17 of chip U1, and pin 6 of chip U2 is connected to pin 18 of chip U1. The pressure sensor collects the pressure of the gas in the air cylinder and then transmits it to chip U1 through pins 17 and 18 of chip U1.

[0027] Pin 11 of chip U1 is connected to one end of resistor R2, and the other end of resistor R2 is connected to pin 1 of chip U3. Chip U3 is an optocoupler chip, model number 6N138. Pin 2 of chip U3 is connected to ground, pin 3 of chip U3 is connected to a +24V power supply, and pin 4 of chip U3 is connected to an electrical signal CQF, which is the inflation valve start signal.

[0028] Pin 12 of chip U1 is connected to one end of resistor R3, and the other end of resistor R3 is connected to pin 1 of chip U4. Chip U4 is an optocoupler chip, model number 6N138. Pin 2 of chip U4 is connected to ground, pin 3 of chip U4 is connected to a +24V power supply, and pin 4 of chip U4 is connected to an electrical signal FQF, which is the venting valve start signal.

[0029] When pin 11 of chip U1 outputs a high level, chip U3 is turned on, and pins 3 and 4 of chip U3 are connected, thereby opening the inflation valve.

[0030] When pin 12 of chip U1 outputs a high level, chip U4 is turned on, and pins 3 and 4 of chip U4 are connected, thereby opening the vent valve.
