Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, and more specifically, to a corrugated paperboard forming device. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is a multi-layer adhesive body, which is made of at least one layer of corrugated paper and one layer of boxboard (also called boxboard) and has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons and other packaging materials for fragile goods. It is mainly made of traditional straw pulp and waste paper through pulping to make a raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface. It has high mechanical strength and can withstand collisions and falls during transportation.

[0003] When corrugated cardboard is composite-formed, the multiple layers of cardboard need to be pressed after gluing and stacking. However, the efficiency of traditional pressure pressing is low. In order to improve the pressing efficiency, some forming devices will use electric heating, mostly heating rods or heating wires. However, this method also has certain problems. The heating rods and heating wires are distributed linearly, resulting in uneven heating temperature, which makes various parts of the multiple layers of cardboard flat when pressed, affecting the quality of the finished product.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0018] like Figure 1-4 A corrugated cardboard forming device shown in the figure comprises a conveyor belt 1 for conveying corrugated base cardboard, support frames 2 for installing and fixing the conveyor belt 1 are arranged on both sides of the conveyor belt 1, servo motors 3 are installed on the tops of the two support frames 2, and a lifting member fixed on the inner wall of the support frame 2 is arranged below the servo motor 3. The number of the lifting members is two, and the two lifting members are symmetrically arranged on both sides of the conveyor belt 1. A forming roller member is connected between the two lifting members, and the forming roller member is located above the conveyor belt 1 and moves up and down above the conveyor belt 1 through the lifting member;

[0019] During operation, the corrugated paperboard after multi-layer glue coating and lamination is transported to the conveyor belt 1 of this device through the conveying device, and the corrugated paperboard is transported to the bottom of the lifting member by the conveyor belt 1. The servo motor 3 drives the lifting member to drive the forming roller to move downward above the conveyor belt 1, and the forming roller acts on the corrugated paperboard to press it into shape.

[0020] A limit plate 4 is provided on the inner side walls of the two support frame plates 2, the bottom of the limit plate 4 is flush with the top of the conveyor belt 1, the limit plate 4 is bent in an "L" shape and the edge is flush with the edges of both sides of the conveyor belt 1;

[0021] The limiting plate 4 is used to limit the position of the corrugated paperboard during transportation to prevent jamming and collision between its edge and the edge of the conveyor belt 1.

[0022] The lifting member includes two limit bars 5 fixed on the inner side wall of the support frame plate 2, the two limit bars 5 extend vertically and the bottom ends extend to the inner side of the limit plate 4, and a slider 6 is embedded between the two limit bars 5 and moves up and down along the limit bars 5, and the slider 6 is also attached to the inner side wall of the support frame plate 2;

[0023] A vertically extending screw hole is opened and closed on the slider 6, a rotating screw rod 7 is inserted in the screw hole, the top of the screw rod 7 is connected to the output shaft of the servo motor 3, the bottom of the screw rod 7 extends to the inner side of the limit bar 5 and is flush with the bottom of the limit bar 5, a bearing 8 is fixed on the outer wall of the slider 6 away from the inner side wall of the support frame plate 2, and a rotating shaft 9 is inserted in the bearing 8;

[0024] On the basis of the above, when the servo motor 3 is working, it drives the screw 7 to rotate in the screw hole in the slider 6. The slider 6 is limited by the limit bar 5. When the screw 7 rotates, it drives the slider 6 to move up and down between the limit bars 5. By controlling the rotation direction of the screw 7, the slider 6 can be raised or lowered.

[0025] Furthermore, the limiting plate 4 is located at the bottom end of the limiting strip 5 and the screw rod 7 and fits with them, so as to limit the lifting movable slider 6 and prevent it from falling off the screw rod 7 .

[0026] The forming roller member includes a hollow roller tube 10 and a heating roller 11 located inside the roller tube 10. The heating roller 11 and the roller tube 10 are coaxially arranged. The two ends of the heating roller 11 are fixed on the two side walls of the inner cavity of the roller tube 10. A heating cavity 12 is formed between the outer wall of the heating roller 11 and the inner wall of the roller tube 10. The heating cavity 12 is filled with heat transfer oil 13.

[0027] Among them, the two ends of the pressing roller tube 10 are respectively connected to the rotating shafts 9 of the lifting parts on both sides, and the pressing roller tube 10 is connected to the sliders 6 on both sides through the rotating shafts 9 and bearings 8. When working, the servo motor 3 drives the screw 7 to rotate, drives the sliders 6 on both sides to perform lifting activities, and drives the pressing roller tube 10 to perform lifting activities above the conveyor belt 1, so that the pressing roller tube 10 can act on the corrugated original cardboard on the conveyor belt 1 during the downward movement, and press the corrugated original cardboard into shape.

[0028] A plurality of heating rods 14 arranged in a circular ring are installed inside the heating roller 11 .

[0029] Furthermore, the heating chamber 12 is filled with heat-conducting oil 13, and the heating rod 14 is used to heat the heat-conducting oil 13 by releasing heat, thereby increasing the temperature of the heat-conducting oil 13 and heating the outer roller tube 10. The high thermal conductivity of the heat-conducting oil 13 improves the heating efficiency while making the surface temperature of the roller tube 10 more uniform, so that the surface of the corrugated paperboard is evenly hot-pressed during the hot-pressing of the roller tube 10, and the problem of uneven flatness of some areas of the corrugated paperboard will not occur, thereby improving the quality of the finished product;

[0030] Furthermore, the pressing roller tube 10 will rotate through the rotating shaft 9 and the bearing 8 during operation, which can not only facilitate the hot pressing of the corrugated paperboard, but also mix and stir the internal heat transfer oil 13 to make the temperature more uniform. The heated heat transfer oil 13 is at high temperature and high pressure inside the heating chamber 12, which can provide support for the tube body of the pressing roller tube 10, improve the strength of the tube body, and avoid the phenomenon of depression due to internal hollowness during the hot pressing process.
