DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the utility model provides an automatic paddle device for feeding foam raw materials, comprising a vertically distributed cylindrical tank 3, and two connecting pipes 4 arranged horizontally opposite to each other are fixedly connected on both sides of the cylindrical tank 3. Specifically, when in use, one of the connecting pipes 4 is connected to an inverted T-shaped discharge pipe 18 connected to a silo 17, and a feeding device is installed at the connecting position between the silo 17 and the inverted T-shaped discharge pipe 18; in addition, a blower 19 is provided at one end of the inverted T-shaped discharge pipe 18 away from the connecting pipe 4, and the blower 19 runs continuously to avoid causing the inverted T-shaped discharge pipe 18 to discharge materials unsmoothly; and the other connecting pipe 4 is connected to a feeding pipe 20; a rotating shaft 2 arranged coaxially with the cylindrical tank 3 is rotatably connected to the top surface of the cylindrical tank 3, and the top end of the rotating shaft 2 passes through the cylindrical tank 3 and is transmission-connected to a stepping motor 5 installed on the cylindrical tank 3, and the bottom end of the rotating shaft 2 passes through the cylindrical tank 3 and is located in the cylindrical tank 3 and fixedly connected A paddle 1 is connected and arranged coaxially with the rotating shaft 2. The paddle 1 is a rectangular plate-shaped structure adapted to the inside of the cylindrical tank 3. The stepper motor 5 rotates 90 degrees each time. Specifically, in the initial state, the paddle 1 is perpendicular to the vertical section of the connecting tube 4. At this time, the two connecting tubes 4 can be in a connected state through the cylindrical tank 3, so that under the action of the blower 19, the foam raw material can be transported to the feeding tube 20; and when the stepper motor 5 drives the paddle 1 to rotate 90 degrees, that is, the paddle 1 is parallel to the vertical section of the connecting tube 4, the paddle 1 can block the two connecting tubes 4 to prevent the foam raw material from entering the feeding tube 20. In this way, when the paddle 1 changes its position back and forth, the foam raw material can be fed intermittently when being fed into the mold, that is, the foam raw material can enter the mold in batches. In this way, when the foam raw material expands in the mold, the occurrence of hardening can be reduced, thereby improving the quality of the foam product.

[0023] When the paddle 1 blocks the connection between the two connecting pipes 4, since the blower 19 is continuously running, the foam raw material may sometimes accumulate in the feed pipe 20 connected to the inverted T-shaped feed pipe 18. Figure 1 , Figure 3 and Figure 4 As shown, a vertically distributed loosening device 6 is installed on one of the connecting tubes 4, and the loosening device 6 includes a loosening motor 61 vertically installed on the connecting tube 4. The output shaft of the loosening motor 61 passes through the connecting tube 4 and is transmission-connected to a rotating rod 62 coaxially arranged with the output shaft of the loosening motor 61. Both sides of the rotating rod 62 are installed from top to bottom with a number of horizontally arranged loosening rods 63 adapted to the connecting tube 4. Specifically, when in use, the connecting tube 4 equipped with the loosening device 6 is connected to the inverted T-shaped feeding tube 18, and when the paddle 1 blocks the two connecting tubes 4, the loosening motor 61 is in a stopped state; and when the paddle 1 is perpendicular to the vertical section of the connecting tube 4, the loosening motor 61 can drive the rotating rod 62 to rotate, and the rotating rod 62 can drive the loosening rod 63 to rotate during the rotation process, thereby loosening the foam raw materials accumulated in the connecting tube 4 to avoid affecting the normal feeding; in addition, the loosening device 6 can also break up the agglomerated foam raw materials.

[0024] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, it also includes a control device 7, a time relay 8 and a power supply 9. The power supply 9 is electrically connected to the stepper motor 5, the time relay 8, the control device 7 and the loosening motor 61 respectively. Specifically, the power supply 9 can supply power to the stepper motor 5, the time relay 8, the control device 7 and the loosening motor 61; and the control device 7 is electrically connected to the stepper motor 5, the time relay 8 and the loosening motor 61 respectively. Specifically, the control device 7 is a PLC controller in the prior art. When in use, the time relay 8 can feed back to the control device 7 the time when the paddle 1 blocks the two connecting pipes 4, so that the control device 7 can automatically control the operation of the stepper motor 5 and the loosening motor 61.

[0025] Since the paddle 1 has a certain thickness, and in order to avoid affecting the rotation of the paddle 1 in the cylindrical can 3, there will be a gap between the outer periphery of the paddle 1 and the inner wall of the cylindrical can 3, and in order to make the paddle 1 completely block the two connecting tubes 4, a rubber strip 10 is installed on the outer periphery of the paddle 1 along the circumferential direction of the paddle 1. Specifically, the rubber strip 10 can be deformed when squeezed, so as not to affect the rotation of the paddle 1 in the cylindrical can 3, and when the paddle 1 blocks the two connecting tubes 4, the rubber strip 10 can fit with the inner wall of the cylindrical can 3 to improve the airtightness, so that the paddle 1 can completely block the two connecting tubes 4.

[0026] Further, such as Figure 1 and Figure 2As shown, the rubber strip 10 is connected to the plectrum 1 by a plurality of countersunk bolts 11 distributed circumferentially along the plectrum 1. Specifically, a countersunk hole is provided on the rubber strip 10, and the countersunk hole penetrates the rubber strip 10. When in use, when the rubber strip 10 is connected to the plectrum 1, the screw end of the countersunk bolt 11 penetrates the rubber strip 10 through the countersunk hole and is threadedly connected to the plectrum 1, and the head of the countersunk bolt 11 is located in the countersunk hole, which makes it easy to disassemble and assemble the rubber strip 10 on the plectrum 1.

[0027] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the top surface of the cylindrical tank 3 is opened, and a tank cover 31 is installed at the top surface opening position of the cylindrical tank 3. The tank cover 31 and the cylindrical tank 3 are connected by a plurality of first connecting bolts 32 equidistantly distributed along the circumference of the cylindrical tank 3. Specifically, when the tank cover 31 is connected to the cylindrical tank 3, the screw end of the first connecting bolt 32 is threadedly connected to the cylindrical tank 3 after passing through the tank cover 31, and the head of the first connecting bolt 32 abuts against the tank cover 31, which makes it easy to remove and install the tank cover 31 on the cylindrical tank 3; in addition, the output shaft of the stepping motor 5 is connected to the rotating shaft 2 through a coupling, so that after the tank cover 31 is removed, the paddle 1 can be pulled out of the cylindrical tank 3, and after the coupling is removed, the rotating shaft 2 can be pulled out from the tank cover 31, and at this time, it is easy to replace the rubber strip 10 on the paddle 1.

[0028] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, a circular shaft 12 arranged with the axis of the cylindrical tank 3 is fixedly connected to the bottom surface of the paddle 1, and the circular shaft 12 is plugged into the inner bottom surface of the cylindrical tank 3, so that the bottom of the paddle 1 can be limited to prevent the bottom of the paddle 1 from shaking during the rotation process, thereby improving the stability of the paddle 1 during the rotation process.

[0029] The specific way of installing the stepper motor 5 on the cylindrical tank 3 is as follows: Figure 1 , Figure 3 and Figure 4 As shown, an inverted U-shaped plate 13 is detachably fixedly connected to the top surface of the tank cover 31. Specifically, horizontally distributed connecting plates 14 are fixedly connected to both sides of the bottom of the inverted U-shaped plate 13. The connecting plate 14 is connected to the top surface of the tank cover 31 by a second connecting bolt 15, which makes it easy to disassemble and assemble the inverted U-shaped plate 13 on the tank cover 31; and the stepper motor 5 is installed on the top surface of the inverted U-shaped plate 13, and the output shaft of the stepper motor 5 passes through the inverted U-shaped plate 13 and is connected to the rotating shaft 2 by the coupling. Specifically, when in use, after the inverted U-shaped plate 13 and the coupling are removed in turn, the stepper motor 5 can be removed from the cylindrical tank 3, which makes it easy to disassemble and assemble the stepper motor 5 on the cylindrical tank 3.

[0030] The specific method of connecting the connecting pipe 4 with the feeding pipe 20 and the inverted T-shaped feeding pipe 18 is as follows: Figure 1 , Figure 3 and Figure 4 As shown, the end of the connecting pipe 4 away from the cylindrical tank 3 is equipped with a flange 16 coaxially arranged with the connecting pipe 4. Specifically, when in use, the flange 16 is also installed on the feed pipe 20 and the inverted T-shaped discharge pipe 18, so that the connecting pipe 4 can be connected to the feed pipe 20 and the inverted T-shaped discharge pipe 18 by a bolt connection pair.
