Description

Technical Field

[0002] SMC is a new composite material that emerged in the 20th century. It has excellent characteristics such as light weight, low cost, good heat resistance and insulation, stable performance, corrosion resistance, easy molding, good electrical performance and insulation performance. With the gradual maturity of its materials and processes, the application range of SMC sheets is getting wider and wider. However, with the increasingly high requirements of modern manufacturing on the performance of materials, the performance of SMC sheets needs to be further improved; during the production process of SMC sheet machine, the materials in the reactor need to be evenly laid on the film surface of the conveyor belt for production and processing by SMC sheet machine.

[0003] A Chinese patent with authorization announcement number CN206733642U discloses a new type of SMC sheet machine, which relates to the field of SMC sheet machines. A sheet film conveying device is arranged on the left side of the glass fiber conveying device, located in the middle of the table top of the machine body. A second resin collecting tank is arranged on the sheet film conveying device, and a second resin conveying pipe is arranged above the second resin collecting tank. A first molded rolling belt is arranged below the sheet film conveying device, and rolling belt conveying shafts are respectively arranged at both ends of the first molded rolling belt. Several rolling belt molded conveying shafts are arranged below the molded rolling belt, and a second molded rolling belt is arranged on the left side of the first molded rolling belt.

[0004] The above-mentioned disclosed patent still has the following technical defects: when the resin collection tank is applied with glue to the membrane body, since the resin collection tank is arranged above the membrane body, the length of the discharge hole of the resin collection tank needs to be set equal to the width of the membrane body (if the discharge hole is set shorter, the glue coating will not be comprehensive; if the discharge hole is set too long, excess glue will drip into the working area, causing waste of glue), so it can only be applicable to the glue coating needs of membranes of specific sizes, and the valve needs to be started when the glue coating work is turned on or off.

DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-Figure 2 As shown, an automatic unloading device proposed in this embodiment includes a frame 1, a material box 2, a motor b20, a heating device 13, a stirring device, a winding roller 4, an unwinding roller a5, an unwinding roller b6, an unwinding roller c7, a transmission roller 8, two clamping rollers 3 and two material boxes 9.

[0025] The winding roller 4, unwinding roller a5, unwinding roller b6, unwinding roller c7, transmission roller 8 and two clamping rollers 3 are all rotatably mounted on the frame 1. The two clamping rollers 3 are arranged side by side up and down with a gap reserved. The unwinding roller b6 is located above the clamping roller 3, and the unwinding roller a5 is located below the clamping roller 3; the motor b20 is installed on the frame 1 and its output shaft is connected to the rotating shaft of the winding roller 4; the two material boxes 9 are installed on the frame 1, and the two material boxes 9 are rotatably mounted with glue coating rollers 10.

[0026] The heating device 13 and the stirring device are both installed on the material box 2; the stirring device includes a motor a12, a stirring shaft 14 and a stirring blade 15, the stirring shaft 14 is rotatably installed on the inner side of the material box 2, the stirring blade 15 is installed on the stirring shaft 14, the motor a12 is installed on the outer end of the material box 2 and its output shaft is connected to the stirring shaft 14, the motor a12 is started to drive the stirring shaft 14 to rotate, and then drive the stirring blade 15 to rotate, the rotation of the stirring blade 15 can stir the rubber inside the material box 2 to prevent the rubber from precipitating and help the rubber to be evenly heated to prevent the rubber from solidifying; a discharge pipe 21 is connected between the material box 2 and the two material boxes 9, and the two discharge pipes 21 are installed with solenoid valves 22; a distance sensor 11 is arranged above the material box 2, and the distance sensor 11 is installed on the frame 1; a controller 19 is installed on the frame 1, and the controller 19 is electrically connected to the distance sensor 11 and the two solenoid valves 22.

[0027] The unwinding roller b6 and the unwinding roller a5 are used for unwinding the upper film and the lower film respectively, the unwinding roller c7 is used for unwinding the glass fiber, and the winding roller 4 is used for winding the pressed composite film. The motor b20 drives the winding roller 4 to rotate to pull and wind the composite film. The outer surface of the upper film faces the bottom end during the movement and contacts with the glue coating roller 10 at the upper end, and the upper film drives the glue coating roller 10 to rotate during the movement. The rotation of the glue coating roller 10 can make the glue inside the material box 9 evenly coated on the surface of the glue coating roller 10, and finally coated on the surface of the upper film. The outer surface of the lower film contacts with the glue coating roller 10 during the movement, so that it is covered with glue. Through the setting of the transmission roller 8, the outer surface of the lower film moves from toward the bottom end to toward the top end. The upper and lower films are respectively pressed against the upper and lower surfaces of the glass fiber, thereby completing the production. Working, the distance measuring sensor 11 set can monitor the liquid level height of the material box 9 in real time and feed back the signal to the controller 19. When the liquid level drops below the bottom of the glue coating roller 10, the controller 19 controls the solenoid valve 22 to open, and the glue inside the material box 2 flows into the interior of the material box 9 through the discharge pipe 21. When the internal liquid level height of the material box 9 exceeds the set value, the controller 19 controls the solenoid valve 22 to close, thereby stopping the feeding work; in summary, the upper and lower films drive the glue coating roller 10 to rotate during the movement, and the glue coating roller 10 has its surface covered with glue and coated on the surface of the film body during the rotation, which can complete the automatic gluing work without the aid of any electronic control equipment and valves, can be suitable for the gluing needs of films of different widths, and has the function of automatic gluing, and its applicability is strong.
