[0036] See also Figures 3 to 5 The frame traction device for continuous production of foamed materials of the utility model comprises an active roller 1, a calendering roller 2, a bearing connection block 3, a gap adjustment cylinder 4 and a spare pressure roller assembly 5. The active roller 1 and the calendering roller 2 are arranged opposite to each other, and the two ends of the calendering roller 2 are connected to the bearing connection block 3, and the top of the bearing connection block 3 is detachably mounted on the frame through a bracket, and the bracket is connected to a slide rail (not shown in the figure) on the frame; the side of the bearing connection block 3 is detachably connected to the gap adjustment cylinder 4, and under the guidance of the slide rail, the gap between the calendering roller 2 and the active roller 1 is controlled by the extension and contraction of the piston end of the gap adjustment cylinder 4, so as to adjust the thickness of the foamed material after being taken out of the furnace. The detachable connection method of the bearing connection block 3 and the bracket and the gap adjustment cylinder 4 includes but is not limited to bolts, screws and other connection methods. A spare pressure roller assembly 5 is provided below the active roller 1 and the calendering roller 2, which can realize the lifting and lowering of the spare calendering roller, so that the calendering roller can be disassembled and replaced.

[0037] Specifically, the spare calender roller assembly 5 includes a spare calender roller 51, a spare calender roller bearing connection block 52, a calender roller crossbeam 53 and a crossbeam slide 54. The calender roller crossbeam 53 is provided on the frame below the active roller 1 and the calender roller 2. The calender roller crossbeam 53 is provided on both sides of the frame for placing the spare calender roller 51 and the replaced calender roller 3. Both ends of the calender roller crossbeam 53 are matched and connected with the vertical crossbeam slide 54 on the frame, respectively, for making the calender roller crossbeam 53 move vertically along the crossbeam slide 54.

[0038] As shown in the figure, a plurality of spare calender rollers 51 are placed on the calender roller beam 53, and spare calender roller bearing connection blocks 52 are arranged at both ends of the spare calender rollers 51, and the calender roller bearing connection blocks 52 are placed on the corresponding calender roller beams 53. Preferably, the spare calender roller bearing connection blocks 52 and the calender roller beams 53 are matched and connected by a concave-convex structure. That is, the groove structure at the bottom of the spare calender roller bearing connection block 52 can be matched and connected with the convex structure at the top of the calender roller beam 53, or the convex structure at the bottom of the spare calender roller bearing connection block 52 can be matched and connected with the groove structure at the top of the calender roller beam 53. On the one hand, the spare calender roller bearing connection block 52 can be moved along the length direction of the calender roller beam 53, and on the other hand, the stability of the spare calender roller 51 during the movement along the calender roller beam 53 and the vertical movement of the calender roller beam 53 along the beam slide 54 can be improved to prevent the spare calender roller from falling.

[0039] When replacing the production of surface pattern products, control the calendering roller beam 53 to move upward along the beam slide groove 54, separate the bearing connecting blocks 3 at both ends of the calendering roller 2 from the frame and the piston end of the gap adjusting cylinder 4 respectively, make the bearing connecting block 3 of the calendering roller 2 fall onto the calendering roller beam 53, move the position of the calendering roller 2 left and right, connect and fix the spare calendering roller bearing connecting block 52 to the frame and the piston end of the gap adjusting cylinder 4 respectively, and then control the calendering roller beam 53 to move downward, thus completing the replacement operation of the calendering roller 2 and the spare calendering roller 51.

[0040] The utility model provides a spare calendering roller assembly, which can quickly replace the calendering roller to produce products with patterns on the surface. Both ends of the spare calendering roller are provided with bearing connecting blocks. At the same time, the connection accuracy of the spare calendering roller and its bearing connecting block is pre-adjusted to ensure the accuracy requirements of the produced products, avoid on-site debugging when replacing the calendering roller, greatly shorten the roller replacement cycle, reduce production costs, and improve production efficiency.

[0041] In a preferred embodiment, a calendering adjustment roller assembly 6 is provided below the spare pressing roller assembly 5 to achieve the production of products with different surface roughness requirements. Figures 3 to 5 As shown, the calendering adjustment roller assembly 6 includes a calendering adjustment roller 61, a roller fixing block 62 and a roller cross beam 63 arranged below the spare calendering roller assembly 5. The roller cross beam 63 is arranged below the calendering roller cross beam 53 and is preferably arranged parallel to it. Roller fixing blocks 62 are arranged at both ends of the calendering adjustment roller 61, and are connected to the roller cross beam 63 through the roller fixing blocks 62. Further preferably, a plurality of mounting holes corresponding to the roller fixing blocks 62 are arranged in the length direction of the roller cross beam 63, so that the calendering adjustment roller 61 can be fixed at different positions in the length direction of the roller cross beam 63. After adjusting the position of the calendering adjustment roller 61 along the length direction of the roller cross beam 63, the roller fixing blocks 62 and the roller cross beam 63 can be fixed by bolts or other mounting parts.

[0042] When producing products with different surface roughness requirements, adjusting the position of the calendering roller 61 can change the size of the wrapping roller between the foaming material and the calendering roller, thereby producing products that meet different surface roughness requirements. Figure 5 As shown, when the calendering adjustment roller 61 moves to the right (the side of the gap adjustment cylinder 4), the larger the area of ​​the foaming material covering the calendering roller 2, the more frictional contact the calendering roller 2 has with the surface of the foaming material when the calendering roller 2 rotates, and the smoother the material surface; conversely, when the calendering adjustment roller 61 moves to the left (away from the side of the gap adjustment cylinder 4), the smaller the area of ​​the foaming material covering the calendering roller 2, the less frictional contact the calendering roller 2 has with the surface of the foaming material when the calendering roller 2 rotates, and the rougher the material surface.

[0043] The utility model can adjust the position of the calendering adjustment roller through the setting of the calendering adjustment roller assembly, and can fix the calendering adjustment roller through the roller fixing block, so as to freely adjust the surface roughness of the produced product, quickly produce products that meet the requirements, reduce debugging production waste, and improve production efficiency.

[0044] In a preferred embodiment, the frame traction device of the utility model further includes a plurality of rollers 7 arranged in the traction path of the foaming material, and the rollers 7 are parallel to the active roller 1 and the calender roller 2. In the specific embodiment shown in the drawings of the utility model, two rollers 7 are arranged, and after the foaming material passes between the active roller 1 and the calender roller 2 to adjust the thickness, it passes through the calender adjustment roller 61 and the two rollers 7 in sequence to be pulled out.

[0045] In a preferred embodiment, the frame traction device of the utility model further comprises a power motor 8 and a belt 10. The power motor 8, the active roller 1 and the over roller 7 are connected by the belt 10, and the power motor 8 outputs the main force, and the belt 10 ensures that the rollers rotate at the same speed.

[0046] In more detail, the frame traction device also includes a steering wheel 9 to adjust the rotation direction of the roller 7. It can be understood by those skilled in the art that the rollers connected under the same belt rotate in the same direction, but in combination with the Figure 5 In order to pull the foaming material out from the traction device, the rotation direction of the last roller 7 needs to be opposite to the rotation direction of other rollers. Therefore, a steering wheel 9 is arranged between the connecting belt of the roller 7 and the power motor 8, so that the rotation direction of the roller 7 can be adjusted to ensure that the foaming material discharged from the oven can be normally and continuously produced along the rotation direction of the roller.

[0047] The utility model makes the active roller and the passing roller rotate autonomously by setting the motor and the belt, and the rotation speed is consistent with the speed of the foaming material coming out of the furnace, so as to avoid the passing roller from stretching and damaging the foaming material which has not been completely cooled and formed, and to avoid the passing roller from getting stuck and slipping to affect the cooling and forming of the foaming material.

[0048] Further preferably, the active roller 1, calender roller 2, roller 7, spare calender roller 51, and calender adjustment roller 61 of the utility model can all pass water to control the roller temperature so as to cool and shape the foaming material in contact with them. The roller passing water can be realized by using the existing technology and will not be described in detail here.

[0049] In addition, the active roller 1, the calendering roller 2, the pass roller 7, the spare calendering roller assembly 5, the calendering adjustment pass roller assembly 6 and the steering wheel 9 are all arranged on the frame, but the utility model does not limit the specific structure of the frame, as long as it can provide support and meet the design conditions of the above structure.

[0050] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
