The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.
[0017] like Figure 1-3 As shown, the utility model is a conductive foam processing rapid coating device, including a support frame 1, a transmission component 2 is provided above the support frame 1, and the transmission component 2 can transmit the conductive foam to be coated, a shell 3 is provided on one side above the transmission component 2, and a first motor 4 is provided on one side above the shell 3. The rotating shaft of the first motor 4 passes through the shell 3 and is fixedly connected to the hot pressing roller 5. When the first motor 4 is working, the first motor 4 drives the hot pressing roller 5 to rotate, and the conductive foam can be coated by the rotating hot pressing roller 5. A mounting frame 13 is provided above the transmission component 2 away from the shell 3, and a second mounting frame 13 is provided in the middle above the mounting frame 13. Hydraulic cylinder 14, the stroke end of the second hydraulic cylinder 14 passes through the mounting frame 13 and is fixedly connected to the fixed plate 15, an air outlet pipe 16 is provided in the middle part below the fixed plate 15, and a plurality of equally spaced nozzles 17 are provided below the air outlet pipe 16. When the second hydraulic cylinder 14 is working, the second hydraulic cylinder 14 can push the fixed plate 15 to move in the vertical direction. By adjusting the position of the fixed plate 15, the height of the air outlet pipe 16 also changes accordingly. The air outlet pipe 16 can be connected to an external air intake device. After the airflow enters the air outlet pipe 16, the airflow can be ejected through the nozzle 17, so that the airflow ejected by the nozzle 17 can clean the surface of the conductive foam.
[0018] A first hydraulic cylinder 7 is inserted into the upper part of the housing 3 away from the first motor 4. The stroke end of the first hydraulic cylinder 7 passes through the housing 3 and is fixedly connected to the movable plate 8. Four matrix-arranged movable rods 9 are inserted into the outer side of the movable plate 8. The movable rods 9 are movably connected to the movable plate 8, and the movable rods 9 can move vertically on the movable plate 8. The four movable rods 9 are fixedly connected to the U-shaped mounting plate 10 below. An extrusion roller 11 is fixedly installed in the middle of the U-shaped mounting plate 10. When the first hydraulic cylinder 7 is working, the first hydraulic cylinder 7 pushes the movable plate 8 to move in the vertical direction. Through the transmission of the movable rod 9, the U-shaped mounting plate 10 and the extrusion roller 11 also move accordingly. When the extrusion roller 11 contacts the coated conductive foam, the extrusion roller 11 squeezes the coated conductive foam again, thereby effectively improving the tightness of the conductive foam coating.
[0019] A spring 12 is sleeved between the movable plate 8 and the U-shaped mounting plate 10. When the squeezing roller 11 contacts the conductive foam, the spring 12 buffers the pressure exerted by the squeezing roller 11 on the conductive foam, thereby preventing the conductive foam from deforming.
[0020] The transmission assembly 2 includes a fixed frame 21, which is fixedly connected to the support frame 1. A second motor 22 is provided on one side of the fixed frame 21. The rotating shaft of the second motor 22 passes through the fixed frame 21 and is fixedly connected to the active roller 23. A driven roller 24 is provided on the side of the fixed frame 21 away from the active roller 23. The active roller 23 and the driven roller 24 are connected by a transmission belt 25. Both ends of the active roller 23 and the driven roller 24 are movably connected to the fixed frame 21. When the second motor 22 is working, the second motor 22 drives the active roller 23 to rotate, and the driven roller 24 is also rotated through the transmission of the transmission belt 25. The mutual cooperation between the active roller 23 and the driven roller 24 enables the transmission belt 25 to transmit the conductive foam to be coated.
[0021] The shell 3 is located on both sides of the first hydraulic cylinder 7 and is plugged with a first guide rod 6. The first guide rod 6 is fixedly connected to the movable plate 8 below, and the first guide rod 6 and the shell 3 are movably connected. Through the mutual cooperation between the first guide rod 6 and the shell 3, the movement stability of the movable plate 8 is effectively improved.
[0022] The mounting frame 13 is located on both sides of the second hydraulic cylinder 14 and is plugged with a second guide rod 18. The second guide rod 18 is fixedly connected to the fixed plate 15 below, and the second guide rod 18 and the mounting frame 13 are movably connected. Through the mutual cooperation between the second guide rod 18 and the mounting frame 13, the movement stability of the fixed plate 15 is effectively improved.
[0023] Specifically, in the present invention, the second motor 22 drives the active roller 23 to rotate, and the driven roller 24 is also rotated through the transmission of the transmission belt 25. The active roller 23 and the driven roller 24 cooperate with each other, so that the transmission belt 25 can transmit the conductive foam to be coated. The second hydraulic cylinder 14 can push the fixed plate 15 to move in the vertical direction. By adjusting the position of the fixed plate 15, the height of the air outlet pipe 16 is also changed. The air outlet pipe 16 can be connected to an air intake device. After the airflow enters the air outlet pipe 16, the airflow can be ejected through the nozzle 17, so that the airflow ejected by the nozzle 17 can be used to move the surface of the conductive foam. Cleaning, the first motor 4 drives the hot pressing roller 5 to rotate, and the conductive foam can be coated by the rotating hot pressing roller 5. The first hydraulic cylinder 7 pushes the movable plate 8 to move in the vertical direction. Through the transmission of the movable rod 9, the U-shaped mounting plate 10 and the squeezing roller 11 also move accordingly. When the squeezing roller 11 contacts the coated conductive foam, the squeezing roller 11 squeezes the coated conductive foam again, thereby effectively improving the tightness of the conductive foam coating. At the same time, when the squeezing roller 11 contacts the conductive foam, the spring 12 buffers the pressure of the squeezing roller 11 on the conductive foam, thereby avoiding deformation of the conductive foam.
[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
