[0003] In the working environment of PP nonwoven fabric hot rolling processing, the hot rolling process is crucial. It uses high temperature and strong pressure to melt PP fibers and bond them together to form a stable mesh structure. However, this process is full of challenges. Due to the complex working environment, the material may experience uneven heating and pressure differences, which can lead to shrinkage, twisting, or wavy deformation of the PP nonwoven fabric. Therefore, this utility model proposes a PP nonwoven fabric hot rolling processing device to solve the above problems. Utility Model Content

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a PP nonwoven fabric hot rolling processing device, including a main frame, a support frame and a fixed frame. The support frame is fixedly connected to one side of the top of the main frame, and the fixed frame is fixedly connected to the other side of the top of the main frame. The fixed frame is provided with a feeding mechanism, the top of the fixed frame is provided with a rolling mechanism, the bottom of the fixed frame is provided with a pressure platform, and a hot rolling chamber is provided on one side of the pressure platform.

The cylinder is fixedly installed on the top of the sliding frame, and the output end of the cylinder is fixedly connected to the top of the connecting frame.

[0007] A further improvement is that: the top of the fixed frame is symmetrically fixedly connected to two track rods on both sides, the two sides of the sliding frame are slidably connected to the outer sides of the two track rods respectively, and the top of the fixed frame is provided with a drive mechanism.

[0008] A further improvement is that the driving mechanism includes a lead screw and a drive motor. The lead screw is rotatably connected to the middle of the top of the fixed frame, and the drive motor is fixedly installed on one side of the top of the fixed frame. The output end of the drive motor is fixedly connected to one end of the lead screw, and the lead screw passes through the interior of the sliding frame and is threadedly connected to it.

[0009] A further improvement is that the feeding mechanism includes a rotary motor, a rotary shaft, pulleys and a belt. The top of the support frame is rotatably connected to the rotary shaft, and a rotary motor is fixedly installed on one side of the support frame. The output end of the rotary motor and one end of the rotary shaft are both fixedly connected to pulleys, and the two pulleys are connected to each other by a belt.

[0010] A further improvement is that the hot rolling silo includes hot rolling rolls and a shell, with two hot rolling rolls rotatably mounted on the top and bottom of the shell, respectively, and one end of the hot rolling rolls being rotatably connected to a connecting pipe via a sealed bearing.

[0011] A further improvement is that a speed-regulating motor is fixedly installed on one side of the housing, and transmission teeth are fixedly connected to the ends of the two hot rolling rollers away from the connecting pipe. The two transmission teeth mesh with each other, and one section of them is fixedly connected to the output end of the speed-regulating motor.

[0012] The beneficial effects of this utility model are as follows: the output end of the cylinder can drive the connecting frame to move downward along the length of the guide rod, thereby driving the rolling roller to squeeze the nonwoven fabric. The drive motor drives the lead screw to rotate forward and backward, which can drive the sliding frame to move linearly back and forth. The rolling roller is hinged below the sliding frame and is used to drive the rolling roller to roll back and forth on the nonwoven fabric.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a PP nonwoven fabric hot rolling processing device, including a main frame 1, a support frame 2, and a fixed frame 3. The support frame 2 is fixedly connected to one side of the top of the main frame 1, and the fixed frame 3 is fixedly connected to the other side of the top of the main frame 1. The fixed frame 3 is provided with a feeding mechanism, a rolling mechanism is provided at the top of the fixed frame 3, a pressure platform 4 is provided below the fixed frame 3, and a hot rolling chamber 5 is provided on one side of the pressure platform 4. The feeding mechanism drives one end of the fiber web roll to move forward automatically, so that one end of the fiber web roll passes through the interior of the hot rolling chamber 5 and is hot rolled into nonwoven fabric. Then the nonwoven fabric falls on the top of the pressure platform 4, and the rolling mechanism squeezes the nonwoven fabric downwards, flattening it before it is completely solidified.

[0019] The rolling mechanism includes a sliding frame 6, a guide rod 7, a connecting frame 8, a rolling roller 9, and a cylinder 10. The sliding frame 6 is installed on the top of the fixed frame 3. The guide rods 7 are symmetrically slidably connected to both sides of the sliding frame 6. The connecting frame 8 is fixedly connected to the bottom end of the guide rod 7. The rolling roller 9 is hinged to the bottom of the connecting frame 8. The cylinder 10 is fixedly installed on the top of the sliding frame 6. The output end of the cylinder 10 is fixedly connected to the top of the connecting frame 8. The output end of the cylinder 10 can drive the connecting frame 8 to move downward along the length of the guide rod 7, thereby driving the rolling roller 9 to squeeze the nonwoven fabric and flatten it before it is completely solidified. Then, the output end of the cylinder 10 can drive the rolling roller 9 to move upward and reset.

[0020] The fixed frame 3 has symmetrically fixed track rods 11 on both sides of its top. The sliding frame 6 is slidably connected to the outer sides of the two track rods 11 on both sides. The fixed frame 3 has a drive mechanism on its top, which includes a lead screw 12 and a drive motor 13. The lead screw 12 is rotatably connected to the middle of the top of the fixed frame 3. The drive motor 13 is fixedly installed on one side of the top of the fixed frame 3. The output end of the drive motor 13 is fixedly connected to one end of the lead screw 12. The lead screw 12 passes through the interior of the sliding frame 6 and is threadedly connected to it. The track rods 11 restrict the movement trajectory of the sliding frame 6. The lead screw 12 is threadedly engaged with the sliding frame 6. The drive motor 13 drives the lead screw 12 to rotate in both directions, which can drive the sliding frame 6 to move back and forth in a straight line. The rolling roller 9 is hinged below the sliding frame 6 and is used to drive the rolling roller 9 to roll back and forth on the non-woven fabric to ensure the flatness of the non-woven fabric.

[0021] The feeding mechanism includes a rotary motor 14, a rotary shaft 15, pulleys 16, and a belt 17. The rotary shaft 15 is rotatably connected to the top of the support frame 2, and the rotary motor 14 is fixedly installed on one side of the support frame 2. The output end of the rotary motor 14 and one end of the rotary shaft 15 are both fixedly connected to pulleys 16. The two pulleys 16 are connected to each other by a belt 17. The belt 17 and the pulleys 16 are designed with a toothed structure to adapt to high-precision transmission. The output end of the rotary motor 14 drives the rotary shaft 15 to rotate through the pulleys 16 and the belt 17. The rotary shaft 15 can drive the fiber web roll to rotate, thereby driving the fiber web roll to move forward automatically for feeding.

[0022] The hot rolling chamber 5 includes hot rolling rolls and a shell. Two hot rolling rolls are rotatably mounted on the top and bottom of the shell, respectively. One end of the hot rolling rolls is rotatably connected to a connecting pipe through a sealed bearing. A speed-regulating motor is fixedly installed on one side of the shell. The ends of the two hot rolling rolls away from the connecting pipe are fixedly connected to transmission teeth. The two transmission teeth mesh with each other, and one section is fixedly connected to the output end of the speed-regulating motor. The heat transfer oil is heated to the target temperature by an electric furnace and circulated to the inside of the hot rolling rolls by a hot oil pump. The speed-regulating motor and the transmission teeth drive the two hot rolling rolls to rotate simultaneously in different directions. After the fiber web enters the hot rolling chamber 5, the upper and lower hot rolling rolls melt the fiber contact points through a high temperature (usually 235-240℃) and a pressure (0.8-1.2MPa). After cooling, thermal bonding points are formed, giving the nonwoven fabric strength and stability.

[0023] In this PP nonwoven fabric hot rolling processing device, the output end of the cylinder 10 can drive the connecting frame 8 to move downward along the length of the guide rod 7, thereby driving the rolling roller 9 to squeeze the nonwoven fabric. The drive motor 13 drives the lead screw 12 to rotate forward and backward, which can drive the sliding frame 6 to move linearly back and forth. The rolling roller 9 is hinged below the sliding frame 6 and is used to drive the rolling roller 9 to roll back and forth on the nonwoven fabric, flattening the nonwoven fabric before it is completely solidified.
