Description

Technical Field

[0001] The utility model relates to the technical field of single-sided machines, in particular to a corrugating line single-sided machine. Background Art

[0002] The single-facer consists of a paper roll holder and a single-faced corrugated forming machine. First, the corrugated core paper is heated, then passed through the corrugating roller to form the required flute shape, and finally glue (starch adhesive) is applied to the flute peaks and bonded with the single-faced corrugated surface paper to form a single-faced corrugated board. The single-facer is one of the important equipment in the corrugated board production line.

[0003] In order to improve the efficiency of corrugated cardboard production, the existing technology has made many improvements to the single-facer of the corrugated line. For example, the patent with patent publication number CN215551391U discloses a single-facer for a corrugated production line, which belongs to the technical field of production equipment. It includes a frame and an upper corrugated roller, a lower corrugated roller, a pressure roller and a glue coating roller. A rotating shaft is provided in the middle of the pressure roller. Both ends of the rotating shaft cross the frame and are exposed outside the frame. A limiting hole adapted to the rotating shaft is provided on the side wall of the frame. An external bearing is sleeved on the end of the rotating shaft. An adjusting device and a lifting device are provided at the bottom of the external bearing; the adjusting device includes a fixed seat, a worm is provided in the fixed seat, a worm wheel meshing with the worm, a screw longitudinally arranged in the middle of the worm wheel, and a support member screwed to the top of the screw, and the support member is connected to the external bearing; the lifting device includes a base, a telescopic rod and a loose screw on the base, a support plate is provided on the top of the telescopic rod, and the support plate is connected to the external bearing. The single-facer machine of the utility model is provided with an adjusting device and a lifting device on both sides of the frame to ensure that the pressure roller can be moved, and can produce corrugated paper boards of different thicknesses, with high production efficiency and low cost.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the pressure roller can be adjusted by the adjusting device and the lifting device, thereby realizing the production of corrugated cardboards of different thicknesses. However, in actual operation, the glue coating thickness of the corrugated cardboard also determines the final quality of the corrugated cardboard. The distance between the glue coating roller and the corrugated paper determines the gluing effect on the corrugated paper. Therefore, the position of the glue coating roller must also be appropriately adjusted according to the thickness of the corrugated paper. Therefore, there is an urgent need in this field to improve the corrugated line single-facer to solve the defects of the existing technology. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1-Figure 5 , a single-sided corrugator comprises a chassis 1, with a feed port 2 and a discharge port 3 respectively provided on opposite sides of the chassis 1, and a pressure roller 4, an upper corrugated roller 5, a lower corrugated roller 6, a glue coating roller 7 adapted to the side of the lower corrugated roller 6, and a glue-distributing roller 9 adapted to the glue coating roller 7 are rotatably connected inside the chassis 1. A glue groove 8 adapted to the glue coating roller 7 and the glue-distributing roller 9 is fixedly connected between the inner side walls of the chassis 1. Both ends of the glue coating roller 7 and the glue-distributing roller 9 are fixedly connected to a rotating shaft 10 extending to the outside of the chassis 1, and a limit block 11 with a rectangular cross-section is rotatably connected to the side of the rotating shaft 10. Limiting grooves 14 adapted to the limit block 11 are opened on both sides of the chassis 1, and adjustment units 12 for adjusting the position of the limit block 11 in the limit groove 14 are provided on both sides of the chassis 1. A driving unit 13 for simultaneously driving the two rotating shafts 10 is provided on one side of the chassis 1. The horizontal height of the limit groove 14 is higher than the upper part of the glue groove 8.

[0028] Specifically, the corrugated cardboard enters through the feed port 2, passes through the pressure roller 4, the lower corrugated roller 6 and the upper corrugated roller 5, and is output from the discharge port 3. Glue is provided in the glue groove 8, and the horizontal height of the glue groove 8 is lower than the limit groove 14. During processing, the distance between the glue roller 7 and the lower corrugated roller 6 is adjusted by the adjustment unit 12 according to the thickness of the corrugated cardboard, and the distance between the glue roller 9 and the glue roller 7 is adjusted by the adjustment unit 12. When the positions of the glue roller 7 and the glue roller 9 are adjusted, the limit block 11 slides in the limit groove 14, and the glue roller 9 is used to control the thickness of the colloid on the surface of the glue roller 7. After the positions of the glue roller 7 and the glue roller 9 are adjusted, the cardboard is conveyed, and the glue roller 7 applies glue to the surface of the corrugated cardboard. By adjusting the position of the glue roller 7, the effect of gluing the surface of the corrugated cardboard is improved. At the same time, the setting of the glue roller 9 further improves the uniformity of gluing the corrugated cardboard.

[0029] As a technical optimization solution of the present invention, the adjustment unit 12 includes several first fixing plates 15 fixedly installed on both sides of the chassis 1, and the first fixing plate 15 is threadedly connected to an adjustment bolt 16, one end of which is rotatably connected to one side of the limit block 11, and the side of the adjustment bolt 16 is threadedly connected to a limit nut 17.

[0030] Specifically, when it is necessary to adjust the position of the glue coating roller 7 or the glue distributing roller 9, the adjusting bolt 16 is rotated. When the adjusting bolt 16 rotates, the limit block 11 is driven to move. When the limit block 11 moves, the rotating shaft 10 is driven to move, thereby achieving the effect of adjusting the position of the glue coating roller 7 or the glue distributing roller 9. After the positions of the glue coating roller 7 and the glue distributing roller 9 are adjusted, the limit nut 17 is tightened to limit and fix the position of the adjusting bolt 16.

[0031] As a technical optimization solution of the present invention, the drive unit 13 includes a drive motor 18 fixedly mounted on one side of the chassis 1, and transmission wheels 19 are fixedly mounted on the side surfaces of the ends of the two rotating shafts 10 and the side surfaces of the output ends of the drive motor 18. The sides of the three transmission wheels 19 are provided with transmission belts 20 for transmission, and a tensioning unit 21 for tensioning the transmission belt 20 is provided on one side of the chassis 1.

[0032] Specifically, the drive motor 18 is started, and the output end of the drive motor 18 drives one of the transmission wheels 19 to rotate, and the transmission wheel 19 drives the other two transmission wheels 19 to rotate through the transmission belt 20, thereby achieving the effect of driving the glue coating roller 7 and the glue distributing roller 9 at the same time. Through the setting of the tensioning unit 21, after the positions of the glue coating roller 7 and the glue distributing roller 9 are adjusted, the glue coating roller 7 and the glue distributing roller 9 can still be driven.

[0033] As a technical optimization solution of the present invention, the tensioning unit 21 includes two second fixing plates 22 fixedly installed on one side of the chassis 1, and a movable column 23 passes through the second fixing plate 22. One end of the movable column 23 is fixedly connected to a U-shaped fixing frame 24, and a pressure wheel 25 adapted to the transmission belt 20 is rotatably connected between the opposite side walls of the fixing frame 24. A spring 26 mounted on the side of the movable column 23 is fixedly connected between one side of the second fixing plate 22 and the fixing frame 24.

[0034] Specifically, the cross section of the movable column 23 is rectangular, which limits the position of the fixed frame 24. The tension of the spring 26 pushes the fixed frame 24, and the fixed frame 24 always pushes the pressure wheel 25 on the transmission belt 20, thereby having a tensioning effect on the transmission belt 20.

[0035] As a technical optimization solution of the present invention, a receiving frame 27 is fixedly installed at the bottom of the chassis 1, and a cleaning plate 28 is fixedly connected to the upper part of the receiving frame 27, one side of which is against the side of the glue coating roller 7, and the cleaning plate 28 is elastic.

[0036] Specifically, when the gluing roller 7 is gluing the corrugated cardboard, a large number of fine impurities will adhere to its surface. As time goes by, the impurities on the surface of the gluing roller 7 will increase, thereby affecting the gluing effect on the corrugated cardboard. In this embodiment, the impurities adhered to the side of the gluing roller 7 are cleaned by the cleaning plate 28. The cleaned impurities will flow into the receiving frame 27 and will be centrally processed later. The cleaning plate 28 is elastic, and even if the position of the gluing roller 7 changes, one side of the cleaning plate 28 will be tightly attached to the side of the gluing roller 7, further improving the gluing effect on the corrugated cardboard.

[0037] As a technical optimization solution of the present invention, a scale 29 with scales is fixedly installed on the side of the chassis 1, and an indicator plate 30 adapted to the scale 29 is fixedly connected to the upper side of the limit block 11.

[0038] Specifically, when adjusting the positions of the glue coating roller 7 and the glue distributing roller 9 , the scale position of the scale 29 can be observed through the indicator plate 30 to improve the accuracy of adjusting the positions of the glue coating roller 7 and the glue distributing roller 9 .

[0039] Among them, the above-mentioned drive motor 18 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 18 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
