Description

Technical Field

[0001] This utility model mainly relates to the field of corrugated cardboard production technology, specifically to a corrugated cardboard single-facer. Background Technology

[0002] The single-facer is one of the important pieces of equipment in the corrugated carton production line. It mainly consists of a paper roll support and a single-face corrugation forming machine. First, the corrugated core paper is heated, then it is formed into the required flute shape by the corrugating rollers. Finally, glue is applied to the flute peaks and bonded to the single-face corrugated paper to form single-face corrugated cardboard.

[0003] The corrugated roll assembly mainly consists of an upper corrugated roll and a lower corrugated roll. The upper and lower corrugated rolls heat-press the base paper into corrugated paper with corrugated ripples.

[0004] During the actual implementation process, the inventors discovered the following defects:

[0005] The existing corrugated rolls are difficult to install, and are not convenient for maintenance and replacement. When the corrugated core paper is compressed, paper dust will be generated. After long-term production, it is easy to remain in the gaps between the teeth of the corrugated roll, which is difficult to clean, and is not conducive to the production and shaping of corrugated paper, thus affecting the production quality.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0030] See attached document Figure 1-3 A corrugated cardboard single-facer includes a frame 1. An active compression roller 2 and an auxiliary compression roller 3 are respectively installed within the frame 1 and are meshed together. One end of the active compression roller 2 is connected to a servo motor 4. A silicone dust removal roller 6 and a dust removal roll module 7 are provided on the upper end of the active compression roller 2. One end of the silicone dust removal roller 6 is connected to an eccentric turntable 8 and a hydraulic cylinder 9. The dust removal roll module 7 includes an unwinding assembly 701 and a winding assembly 702. A traction mechanism 703 is provided on one side of the winding assembly 702. The traction mechanism 703 includes a traction roller 7031 and a traction motor 7032. The unwinding assembly 701 and the winding assembly 702 are respectively located on both sides of the silicone dust removal roller 6.

[0031] See attached document Figure 1-3 The silicone dust removal roller 6 is located above the active extrusion roller 2. The width of the silicone dust removal roller 6 is half the width of the active extrusion roller 2. One end of the silicone dust removal roller 6 is fixedly connected to the eccentric turntable 8. The end of the eccentric turntable 8 away from the silicone dust removal roller 6 is provided with a positioning plate 10. The eccentric turntable 8 and the positioning plate 10 are rotatably connected. A rocker arm 5 is also provided on one side of the eccentric turntable 8. The silicone dust removal roller 6 is fixed to the eccentric turntable 8 through a roller shaft. The silicone dust removal roller 6 can rotate on its own. By pushing the rocker arm 5, the eccentric turntable 8 is rotated, causing it to rotate in the direction of the active extrusion roller 2, pressing the silicone dust removal roller 6 against the active extrusion roller 2.

[0032] See attached document Figure 1-3 The positioning disk 10 is provided with a guide assembly 11, and the lower end of the positioning disk 10 is also provided with a sliding rod 12 movably connected thereto. The two ends of the sliding rod 12 are fixedly connected to the frame 1. The guide assembly 11 includes multiple guide posts 1101. One end of the multiple guide posts 1101 is provided with a linkage plate 1102. The other end of the multiple guide posts 1101 away from the linkage plate 1102 passes through the frame 1 and is fixedly connected to the positioning disk 10. One end of the extension rod of the hydraulic cylinder 9 passes through the linkage plate 1102 and is fixedly connected to the frame 1. The positioning disk 10 is connected to the hydraulic cylinder 9 through the guide assembly. After the hydraulic cylinder 9 extends, it pushes out the positioning disk 10, which drives the eccentric turntable 8 and the silicone dust removal roller 6 connected thereto to push out together.

[0033] See attached document Figure 1-3 The unwinding assembly 701 and the winding assembly 702 have the same structure. The unwinding assembly 701 includes a rotary motor 7011, and the drive end of the rotary motor 7011 is connected to a lead screw 7012. The lead screw 7012 is provided with a core 7013, and the dust removal roll paper is installed on the core 7013. After the rotary motor 7011 drives the lead screw 7012, the core 7013 moves back and forth along the lead screw 7012 and is used after cooperating with the position of the silicone dust removal roller 6. The winding assembly 702 is driven by the traction mechanism 703 to rotate and achieve continuous winding.

[0034] In this embodiment, the silicone dust removal roller 6 and the dust removal roll module 7 are placed above the active extrusion roller 2 when not in use. When dust removal is required, the rocker arm 5 is pushed to rotate the eccentric turntable 8, pressing the silicone dust removal roller 6 against the active extrusion roller 2. When the silicone dust removal roller 6 presses down, it presses the dust removal roll paper into the gap between the outer teeth of the active extrusion roller 2. At the same time, the traction mechanism 703 and the servo motor 4 are activated. The traction roller 7031 in the traction mechanism 703 is a cam roller, and the servo motor 4 drives the active extrusion roller 2 to rotate. As the active extrusion roller 2 rotates, the dust removal roll paper removes corrugated paper debris from the gap between the outer teeth of the active extrusion roller 2. Since the width of the dust removal roll paper is limited, this also prevents the dust removal roll paper from being damaged due to its width. If the dimensions are too large, adhesion occurs. Therefore, the silicone dust removal roller 6 can only remove dust from half of the active extrusion roller 2 in sequence. After half of the dust removal is completed, the rocker arm 5 is pushed in the opposite direction to reset the silicone dust removal roller 6 upward. The hydraulic cylinder 9 is activated to push out the guide assembly 11, positioning plate 10, eccentric turntable 8 and silicone dust removal roller 6, so that they are located in the other half of the active extrusion roller 2. At the same time, the unwinding assembly 701 and the winding assembly 702 are activated to move the dust removal roll paper to the position corresponding to the silicone dust removal roller 6. The rocker arm 5 is pushed again to press the dust removal roll paper into the gap between the outer teeth of the active extrusion roller 2. The traction mechanism 703 is activated to remove dust from the other half of the active extrusion roller 2 again.

[0035] In summary, the combined use of silicone dust removal rollers and unwinding components achieves dust and chip removal from the active extrusion rollers. Dust removal can be performed periodically according to production needs, effectively keeping the gap between the active extrusion roller teeth clean and avoiding affecting the quality of corrugated paper production.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
