Description

Technical Field

[0001] This utility model relates to the field of single-sided machines, and more particularly to a belt assembly and a single-sided machine. Background Technology

[0002] A single-facer is a type of paperboard production machine used to produce corrugated cardboard.

[0003] During the lamination process, a belt is used to apply pressure to the face paper to ensure a tight bond between the face paper and the core paper. The characteristic of this type of single-facer is that the corrugated board produced has light indentations (the face paper surface is minimally affected by the indentations).

[0004] However, belts are consumables. Even with continuous 24-hour operation, the lifespan of a belt is only a few months. If maintenance is not timely, the belt will break, leading to a production stoppage. For corrugated paper manufacturers, the number of workers usually includes several hundred, and in this situation, all several hundred workers will have to stop working.

[0005] More importantly, belt replacement is not a simple part replacement, but requires disassembly of the equipment. The entire process requires professional maintenance personnel and will disrupt normal production in the short term. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a belt assembly and a single-facer. By adjusting the gap between the belt roller and the corrugated roller, and by temporarily replacing the belt with a belt roller, production can be quickly restored to cope with situations where all operators are unable to work normally in the short term.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a belt assembly, which is hinged to the gantry frame in a single-facer, with one end of the belt assembly acting as a limiting component against a pad in the gantry frame, the belt assembly including a belt roller, characterized in that the limiting component is provided with a gap adjustment mechanism for shortening the gap between the belt roller and the corrugated roller, so that the belt roller is mounted on the corrugated roller.

[0008] The beneficial effects of this utility model are:

[0009] Adjusting the gap between the belt roller and the corrugating roller provides an emergency solution for this belt assembly. After fine-tuning, the function of the belt roller is changed, and the belt roller temporarily replaces the belt to provide pressure to the corrugated cardboard. As a result, the corrugated cardboard produced can meet other low-requirement orders, ensuring that the entire production line can operate in the most basic state.

[0010] The gap adjustment mechanism includes an eccentric wheel and a lifting block. The lifting block is located at the bottom where the limiting component contacts the pad. The bottom has an opening for installing the lifting block. The opening is reserved with a depth for the lifting block to move inward. The lifting block is fitted onto the eccentric wheel. During the rotation of the lifting block, it drives the lifting block to make fine adjustments in raising and lowering within the opening.

[0011] The adjustment is achieved through a thread. A handle is fitted onto either end of the eccentric wheel. The limiting component is provided with a bolt mounting seat, which has a positioning groove for the positioning adjustment bolt. In this specific embodiment, the bolt mounting seat is inclined, so that the adjustment bolt in the positioning groove is threadedly connected to the handle in an inclined state. In this state, turning the adjustment bolt causes the entire handle to rotate, and the rotation of the handle drives the rotation of the eccentric wheel.

[0012] It should be noted that the lifting block and the eccentric wheel slide together, the bottom surface of the lifting block is parallel, and the eccentric wheel passes through the area above or near the top of the lifting block. This allows the bottom surface of the lifting block to always face downwards under natural gravity.

[0013] The belt assembly includes a pressure roller and a belt roller seat. The belt roller seat is provided in pairs. The belt roller and the pressure roller are located at the two ends of the belt roller seat and are rotatably connected to the belt roller seat. The end of the belt roller seat corresponding to the belt roller is a hinged end that is rotatably connected to the gantry frame. There is a gap between the belt roller and the pressure roller. The belt roller and the pressure roller are fitted with the same belt. The belt roller seat presses the belt onto the corrugated roller by rotating.

[0014] When a belt breaks, the entire belt roller seat is lifted, the pad is removed, and the eccentric wheel is adjusted to retract the lifting block into the opening. This changes the distance between the belt roller and the corrugated roller, altering the roles of the belt roller and the pressure roller in subsequent production. For example, previously there was a 4mm gap between the belt roller and the corrugated roller, which ensured that the belt pressed the face paper firmly onto the core paper on the corrugated roller. When the belt breaks, it is pulled out directly, and the distance between the belt roller and the corrugated roller is readjusted using the eccentric wheel. This allows the belt roller to directly press the paper onto the corrugated roller. In other words, the belt roller replaces the belt, pressing the face paper onto the core paper of the corrugated roller, while the pressure roller acts as a guide for the corrugated board.

[0024] A belt assembly is hinged to a gantry frame 2 in a single-facer. One end of the belt assembly 1 serves as a limiting component 3 and abuts against a pad 4 in the gantry frame 2. The belt assembly includes a belt roller 100. The limiting component 3 is provided with a gap adjustment mechanism 5 for shortening the gap between the belt roller 100 and the corrugated roller, so that the belt roller 100 is mounted on the corrugated roller.

[0025] The beneficial effects of this utility model are:

[0026] Adjusting the gap between the belt roller 100 and the corrugated roller provides an emergency measure for this belt assembly 1. After fine-tuning, the function of the belt roller 100 is changed, and the belt roller 100 temporarily replaces the function of the belt to provide pressure to the corrugated cardboard. As a result, the corrugated cardboard produced can meet other low-requirement orders, ensuring that the entire production line can be in the most basic operating condition.

[0027] The gap adjustment mechanism 5 includes an eccentric wheel 51 and a lifting block 52. The lifting block 52 is located at the bottom where the limiting member 3 contacts the pad 4. The bottom has an opening for installing the lifting block 52. The opening is reserved with a depth for the lifting block 52 to move inward. The lifting block 52 is sleeved on the eccentric wheel 51. During the rotation of the lifting block 52, the lifting block 52 is driven to make fine adjustments in raising and lowering within the opening.

[0028] The adjustment is achieved through a thread. A handle 53 is fitted onto either end of the eccentric wheel 51. The limiting component 3 is provided with a bolt mounting seat 54. The bolt mounting seat 54 has a positioning groove 54a for the positioning adjustment bolt 55. In this specific embodiment, the bolt mounting seat 54 is inclined, so that the adjustment bolt 55 in the positioning groove 54a is threadedly connected to the handle 53 in an inclined state. In this state, turning the adjustment bolt 55 causes the entire handle 53 to rotate, and the rotation of the handle 53 drives the rotation of the eccentric wheel 51.

[0029] It should be noted that the lifting block 52 and the eccentric wheel 51 slide together. The bottom surface of the lifting block 52 is parallel, and the eccentric wheel 51 passes through the upper part or near the upper part of the lifting block 52. This allows the bottom surface of the lifting block 52 to always face downwards under natural gravity.

[0030] The belt assembly 1 includes a pressure roller 101 and a belt roller seat 102. The belt roller seat 102 is provided with a pair of belt rollers 100 and pressure rollers 101 located at the two ends of the belt roller seat 102 and rotatably connected to the belt roller seat 102. The end of the belt roller seat 102 corresponding to the pressure roller 101 is a hinged end rotatably connected to the gantry frame 2. There is a gap between the belt roller 100 and the pressure roller 101. The belt roller 100 and the pressure roller 101 are fitted with the same belt 6. The belt roller seat 102 presses the belt 6 onto the corrugated roller by rotating.

[0031] When the belt breaks, the entire belt roller seat 102 is lifted, the pad 4 is removed, and the eccentric wheel 51 is adjusted to retract the lifting block 52 into the opening. This changes the distance between the belt roller 100 and the corrugated roll, altering the function of the belt roller 100 and the pressure roller 101 in subsequent production. For example, previously, there was a 4mm gap between the belt roller 100, the pressure roller 101, and the corrugated roll. This gap ensured that the belt 6 pressed the face paper firmly onto the core paper on the corrugated roll. When the belt 6 breaks, it is pulled out directly, and the distance between the belt roller 100, the pressure roller 101, and the corrugated roll is readjusted using the eccentric wheel 51. This allows the belt roller 100 to directly press the paper onto the corrugated roll. In other words, the belt roller 100 replaces the function of the belt 6, pressing the face paper onto the core paper of the corrugated roll, while the pressure roller 101 acts as a guide for the corrugated board.
