Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a pre-pressing roller assembly for improving heat conduction effect. Background Technique

[0002] In the process of producing non-woven fabrics, steps such as melting, spinning, hot pressing, and winding are required. The pre-pressing roller is one of the important equipment in hot pressing. Through its structural design, such as the cooperation of the upper pressing roller and the lower pressing roller, the pre-pressing roller ensures that the non-woven fabric is subjected to uniform pressure during production, avoids the phenomenon of web turning and breaking, and ensures the tightness and uniformity of the non-woven fabric.

[0003] The prior art discloses the patent application number "CN202220977417.3", a pre-pressing roller for a non-woven fabric lapping machine, including an installation table, an upper pressing roller, a lower pressing roller and a cross plate. The upper pressing roller is installed at the bottom of the cross plate through an installation frame, and the upper pressing roller is rotatably connected to the installation frame. The setting of the positioning component can move the cross plate to the outside of the lower pressing roller, which is time-saving and labor-saving. One person can complete the operation during operation, which is convenient for users to maintain the lower pressing roller and the upper pressing roller, expands the maintenance space, and reduces the visual blind area.

[0004] This pre-pressing roller can only realize the maintenance of the lower pressing roller and the upper pressing roller. However, in actual use, the installation space of the pre-pressing roller is limited as described above, making it impossible to conveniently install pre-pressing rollers of different specifications and lengths, resulting in poor applicability of the pre-pressing roller. At the same time, the heat conduction of the pre-pressing roller itself is poor, so the hot pressing of the pre-pressing roller is not uniform enough, which affects the hot pressing effect of the pre-pressing roller assembly and is not convenient to use. Content of the Utility Model

[0028] The hot pressing roller body 4 is clamped inside the telescopic seat 7. A ring 10 is fixedly connected to the outer surface of the hot pressing roller body 4. Positioning columns 11 are arrayedly connected to the left side of the ring 10. A ceramic outer shell 8 is clamped to the outer surface of the hot pressing roller body 4.

First springs 13 are connected between the two telescopic convex rods 12 and the hot pressing roller body 4. Heating rods 23 are fixedly arranged in an array inside the hot pressing roller body 4.

[0029] The second guide frame 5 is located below the first guide frame 3. Fastening bolts 9 for fixing the telescopic seat 7 are threadedly connected to one side of the four rotating shafts 6. Rubber sleeves 14 are connected inside the four telescopic seats 7. Through the setting of the rubber sleeves 14, the rubber sleeves 14 can be more tightly attached to the hot pressing roller body 4, ensuring the stability during the installation of the hot pressing roller body 4.

[0030] A plurality of movable circular seats 21 are slidably connected to one side inside the hot pressing roller body 4. A plurality of U-shaped limiting plates 24 are slidably connected to the inner side surface of the hot pressing roller body 4. Second springs 22 are installed between the movable circular seats 21 and the hot pressing roller body 4. Third springs 25 are installed between the U-shaped limiting plates 24 and the hot pressing roller body 4. The movable circular seats 21 and the U-shaped limiting plates 24 are used to fix the heating rods 23.

[0031] Inside the main body 2 of the pre-pressing roller assembly, a double-headed lead screw 15 is rotatably connected. Symmetrically arranged first lifting support plates 16 and second lifting support plates 17 are threadedly connected to the outer surface of the double-headed lead screw 15. The second lifting support plate 17 is located below the first lifting support plate 16. A servo motor 20 is fixedly connected to the lower side of the double-headed lead screw 15 through a motor mounting plate. Inside the main body 2 of the pre-pressing roller assembly, two smooth rods 18 arranged in parallel are connected. Through the arrangement of the smooth rods 18, the two guide frames can drive the two hot pressing roller bodies 4 to move and adjust smoothly by cooperating with the smooth rods 18 and the first guide frame 3 and the second guide frame 5, improving the reliability of the pre-pressing roller assembly during use.

[0034] The working principle of a pre-pressing roller assembly for improving heat conduction effect provided by the present utility model is as follows:

[0035] By moving the ceramic shell 8 to the left side of the hot pressing roller body 4, and then pressing the two telescopic convex rods 12 with the first springs 13 installed at the hot pressing roller body 4, the two telescopic convex rods 12 can be retracted. Subsequently, the ceramic shell 8 is pushed and clamped to the hot pressing roller body 4. At the same time, the positioning columns 11 at the ring 10 can further position the ceramic shell 8. At this time, the ceramic shell 8 can cover the hot pressing roller body 4 to improve the heat conduction effect of the hot pressing roller body 4, reduce the adhesion of the hot pressing roller body 4 to the material. The heat conduction efficiency of the ceramic shell 8 itself is high, making the heat distribution uniform, thereby affecting the hot pressing effect of the pre-pressing roller assembly and reducing energy consumption. Then, the two hot pressing roller bodies 4 are respectively moved to the two telescopic seats 7, and then the telescopic seats 7 at the rotating shaft 6 are pushed, so that the telescopic seats 7 can be clamped and fixed to both ends of the hot pressing roller body 4. Then, the fastening bolts 9 are rotated to squeeze and position the telescopic seats 7 to ensure the stability of the two hot pressing roller bodies 4 during installation. In this way, hot pressing roller bodies 4 with different specifications and lengths can be conveniently installed, improving the installation efficiency of the pre-pressing roller assembly;

[0036] By inserting the heating rod 23 into the U-shaped limiting plate 24 equipped with the third spring 25 and then moving the heating rod 23, the heating rod 23 is clamped into the movable circular seat 21 equipped with the second spring 22, so that the heating rod 23 can be limited and fixed, facilitating the flexible loading and unloading of the heating rod 23, saving time and effort. At the same time, the heating rods 23 are fixed inside the hot pressing roller body 4 in an array distribution manner to further improve the heat conduction effect of the pre-pressing roller assembly. Then, the output shaft of the servo motor 20 drives the double-headed lead screw 15 to rotate, enabling the first lifting support plate 16 and the second lifting support plate 17 on the double-headed lead screw 15 to move towards each other, for adjusting the hot pressing pressure of the upper and lower hot pressing roller bodies 4 to uniformly hot press the non-woven fabric and improve the hot pressing effect of the pre-pressing roller assembly.
