Description

Technical Field

[0001] This utility model relates to a roller assembly formed by extrusion of double honeycomb panels, belonging to the technical field of honeycomb panel processing. Background Technology

[0002] In the field of double honeycomb panel manufacturing, vacuum roller adsorption molding technology has become a key means of extrusion molding process due to its advantages of high precision and high efficiency. By constructing a vacuum system inside the roller, the adsorption force generated by the air pressure difference is used to tightly adhere the heated and softened extruded material to the roller surface, thereby achieving precise molding of the honeycomb structure. However, in the actual production process, due to the structural characteristics of the extruded material itself, the adsorption and bonding effect of the two sides of the extruded material during vacuum roller adsorption molding is significantly different from that of the middle area due to the presence of cross sections. Air can easily penetrate through the cross sections on both sides, resulting in a significant reduction in the air pressure difference at the edges, which greatly weakens the vacuum adsorption force. This phenomenon makes it difficult for the two sides of the extruded material to be tightly adhered to the surface of the vacuum roller, which not only causes a decrease in the precision of the honeycomb panel edge structure and damage to the surface flatness, but may also cause local stress concentration, reducing the mechanical properties and appearance quality of the product. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a roller assembly for extruding double honeycomb panels, which solves the problem of poor adhesion between the two edges of the extruded body during the vacuum roller adsorption process.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A roller assembly for extruding double honeycomb panels includes a frame, a vacuum roller shaft is provided inside the frame, and pressure rollers are provided at both ends of the side of the vacuum roller shaft. A U-shaped frame is also provided on the side of the vacuum roller shaft, and mounting plates are provided at the front and rear ends of the U-shaped frame. The pressure rollers are provided on the side of the mounting plates.

[0006] The U-shaped frame is equipped with an adjustment mechanism, which is used to drive the mounting plate to move vertically.

[0007] Preferably, the adjustment mechanism includes a motor, which is installed outside the U-shaped frame, and a lead screw and a guide rod are respectively provided at both ends inside the U-shaped frame. The lead screw and the guide rod both pass through the mounting plate, and the lead screw is connected to the output end of the motor.

[0008] Preferably, a cylinder is fixed through the side of the frame, and the output end of the cylinder is connected to the U-shaped frame.

[0009] Preferably, the mounting plate has a groove, and a slider is slidably connected in the groove. A spring is fixed to the inner wall of the groove and connected to the slider. One end of the pressure roller is mounted on the slider through a bearing.

[0010] Preferably, the mounting plate has a threaded hole and a through hole, and the lead screw and guide rod pass through the threaded hole and the through hole respectively.

[0011] Preferably, a rubber ring is provided on the outside of the pressure roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) When the extruded body is vacuum adsorbed by the vacuum roller to form the honeycomb panel, the two sets of pressure rollers can apply pressure to both sides of the extruded body, which can directly make up for the problem of insufficient adsorption force caused by the cross section, press the two sides of the extruded body tightly onto the surface of the vacuum roller, reduce air infiltration, enhance the fit between the edge and the vacuum roller, thereby improving the edge structure accuracy and surface flatness of the honeycomb panel and ensuring the overall quality of the product.

[0014] (2) The distance between the two sets of pressure rollers can be adjusted by the adjustment mechanism, which can be flexibly adjusted according to the width of the extruded body. This makes the technical solution applicable to the production of extruded bodies of different specifications and widths. Whether it is a narrow or wide honeycomb panel, good edge bonding can be achieved by adjusting the distance between the pressure rollers, which significantly improves the versatility and flexibility of the production process.

[0022] A roller assembly for extruding double honeycomb panels includes: a frame 1, a vacuum roller 2 is provided inside the frame 1, and pressure rollers 3 are provided at both ends of the side of the vacuum roller 2. A U-shaped frame 4 is also provided on the side of the vacuum roller 2, and mounting plates 5 are provided at the front and rear ends of the U-shaped frame 4. The pressure rollers 3 are provided on the side of the mounting plates 5.

[0023] The U-shaped frame 4 is equipped with an adjustment mechanism 6, which is used to drive the mounting plate 5 to move vertically.

[0024] Furthermore, by applying pressure to both sides of the extruded body through two sets of pressure rollers 3, the problem of insufficient adsorption force caused by the cross section can be directly compensated, and the two sides of the extruded body can be tightly pressed onto the surface of the vacuum roller shaft 2, reducing air infiltration and enhancing the fit between the edges and the vacuum roller shaft 2.

[0025] In this embodiment: the adjustment mechanism 6 includes a motor 601, which is installed outside the U-shaped frame 4. The U-shaped frame 4 has a lead screw 602 and a guide rod 603 at both ends inside. The lead screw 602 and the guide rod 603 both pass through the mounting plate 5, and the lead screw 602 is connected to the output end of the motor 601.

[0026] Furthermore, by driving the lead screw 602 to rotate via the motor 601, the lead screw 602 can cause the two sets of mounting plates 5 connected to it by threads to move closer or further apart, thereby adjusting the distance between the two sets of pressure rollers 3 and realizing the production of extruded materials of different specifications and widths.

[0027] In this embodiment: a cylinder 7 is fixed through the side of the frame 1, and the output end of the cylinder 7 is connected to the U-shaped frame 4.

[0028] Furthermore, the cylinder 7 can drive the U-shaped frame to move laterally, so as to adjust the distance between the pressure roller 3 and the vacuum roller shaft 2 and improve its functionality.

[0029] In this embodiment: a groove 8 is provided on the mounting plate 5, and a slider 9 is slidably connected in the groove 8. A spring 10 is fixed on the inner wall of the groove 8, and the spring 10 is connected to the slider 9. One end of the pressure roller 3 is mounted on the slider 9 through a bearing.

[0030] Furthermore, the spring 10 allows the slider 9 and the pressure roller 10 to move adaptively when the pressure roller 3 applies pressure to the extruded material, so as to avoid excessive pressure on the extruded material and deformation.

[0031] In this embodiment: the mounting plate 5 has threaded holes and through holes, and the lead screw 602 and guide rod 603 pass through the threaded holes and through holes respectively.

[0032] Furthermore, the guide rod 603 can guide the movement of the mounting plate 5.

[0033] In this embodiment: a rubber ring is provided on the outside of the pressure roller 3.

[0034] Furthermore, the rubber ring also prevents the pressure roller 3 from damaging the extruded material.

[0035] The workflow of this embodiment is as follows: When the extruded body is bonded to the surface of the vacuum roller shaft 2 for negative pressure forming, the cylinder 7 can be opened to drive the U-shaped frame 4 and the pressure roller 3 to approach the vacuum roller shaft 2, so that the pressure roller 3 applies pressure to both sides of the extruded body on the surface of the vacuum roller shaft 2, thereby making the two sides of the extruded body tightly bonded to the surface of the vacuum roller shaft 2. In addition, the spring 10 in the side groove 8 of the mounting plate 5 can make the slider 9 and the pressure roller 10 move adaptively when the pressure roller 3 applies pressure to the extruded body, so as to avoid excessive pressure on the extruded body and deformation. When it is necessary to vacuum form extruded bodies of different widths, the motor 601 can be turned on to drive the lead screw 602 to rotate, so that the lead screw 602 drives the two sets of mounting plates 5 connected to it to move closer or further apart, thereby adjusting the distance between the two sets of pressure rollers 3, so as to realize the production of extruded bodies of different specifications and widths.
