Description

Technical Field

[0001] This utility model relates to a flipping device, and more particularly to a flipping table for a rewinding machine. Background Technology

[0002] The toilet paper initially rolled out by the paper machine is rewound by the rewinder to the required number of layers, width, and diameter. After rewinding, the roll is unwound onto a tilting table for unwinding, cutting, and tidying. The tidyed roll is then fed to the rear platform by the tilting table. The rear platform has stops; lowering the stops sends the roll to the packaging machine via a conveyor belt. The stops on the rear platform can be partially or fully lowered to allow for selection of the roll's unwinding amount and also serve as a buffer. Normally, the tilting table faces the rewinder platform; it only turns towards the rear platform when the rewound roll needs to be sent. When the tilting table is on either the rewinder or the rear platform, there is a gap between the tilting table and the other platform. This gap only exists briefly when the tilting table is transporting the roll; however, the gap between the tilting table and the rear platform is approximately 45cm and is present normally. During this time, workers may be working in this gap, increasing the risk of falling and sustaining injuries such as pinching, fractures, or even more serious personal injury. Furthermore, the rear platform of the turnover table has a stop. When the turnover table conveys the paper roll to the rear platform, the paper roll is easily bounced back by the stop and rolls back to hit the edge of the turnover table. Since the contact surface is a narrow and sharp line, it can easily cut the paper roll. The damaged part needs to be cut off and remelted. The diameter of the remelted paper roll is reduced. When the roll diameter is smaller than the specifications required by the order, it will affect normal warehousing and requires downgrading or remelting, which affects the production line capacity and increases the company's production costs. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a rewinding table for preventing personnel or damaged paper from falling into the gap between the rewinding table and the front and rear worktables and causing injury.

[0004] Technical solution: The rewinding machine turning table of this utility model includes a base, a lifting hydraulic cylinder and a U-shaped worktable. The top of both sides of the U-shaped worktable is inclined downward with baffles, and a support plate is provided on the baffles. The support plate is inclined on the baffles, and the support plate is on the same plane as the platform on the other side when the turning table turns to the rewinding platform or the rear platform.

[0005] Furthermore, the angle between the baffle and the two sides of the U-shaped worktable is 80-90°, and the length of the baffle is equal to the length of the two sides of the U-shaped worktable. The baffle is seamlessly welded to the sides of the U-shaped worktable. When the paper roll rebounds at the rear platform, the baffle replaces the side of the U-shaped worktable in contact with the paper roll, increasing the contact area by replacing line contact with surface contact and preventing the paper roll from being cut and requiring remelting. The length of the support plate is equal to the length of the baffle, and the width is 10cm-15cm. Combined with adjusting the angle between the baffle and the two sides of the U-shaped worktable, it is designed to cover the gap between the flipping platform and the two end platforms as much as possible when flipping, preventing personnel or items from falling into the gap and causing impact. At the same time, it ensures that when the flipping platform turns to the rewinding platform or the rear platform, it is on the same plane as the platform on the other side, preventing steps between the platform and the support plate from causing personnel to fall or bump into each other.

[0006] Furthermore, the baffle is divided into upper and lower parts by the support plate. The upper part is 30cm to 40cm wide and the lower part is 10cm to 20cm wide. The width of the baffle and the width of the upper and lower parts of the baffle are set according to the distance relationship with other surrounding equipment and the position of the support plate on the baffle, so as to prevent the baffle from contacting the platform, other equipment or the ground during the flipping process.

[0007] Furthermore, a support block is provided between the bottom of the support plate and the baffle to enhance the support strength of the support plate. The support block is seamlessly welded to the support plate and the baffle, increasing the support strength of the support plate and further ensuring safety when the upper end bears heavy objects. The support block is inverted conical with an arc-shaped end face at the bottom and a height of 15cm to 25cm. The bottom of the support block slightly exceeds the bottom of the baffle to prevent personnel or paper rolls from being cut by sharp edges. The maximum width of the support block is the same as the width of the support plate, ensuring that the support block does not contact the work platform at the near end or the equipment support or the ground during the tilting process, thus ensuring the safety of the improved tilting table during tilting.

[0008] Furthermore, the tilting table also includes an alarm device connected in series with the tilting table switch, which sounds an alarm when the tilting table tilts to alert nearby workers to pay attention to safety.

[0009] Beneficial effects: Compared with the prior art, the present invention has the following advantages: 1. The gap between the flipping table and the front and rear platform is reduced to a safe range to prevent personnel or damaged paper from falling, thus avoiding personnel injury and increasing the workload and intensity of paper handling; 2. The contact area between the rebounding paper roll and the flipping table is increased, reducing the risk of the paper roll being bumped or cut, improving production efficiency and reducing losses.

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 and 2 The rewinding machine tilting table shown includes a base 1, a lifting hydraulic cylinder 2, and a U-shaped worktable 3. The top of both sides of the U-shaped worktable 3 are welded downwards to baffles 4. Support plates 5 are mounted on the baffles 4 and are welded obliquely to them. Support blocks 6, used to enhance the support strength of the support plates 5, are welded between the bottom of the support plates 5 and the baffles 4. The table also includes an alarm device connected in series with a tilting table switch. The length d of the baffles 4, support plates 5, and support blocks 6 is equal to the length of both sides of the U-shaped worktable 3. The included angle between the baffle 4 and the two sides of the U-shaped worktable 3 is 80-90°. When the tilting table turns to the rewinding platform 7 or the rear platform 8, the support plate 5 is on the same plane as the platform on the other side. The width c of the support plate 5 is 15cm. In actual application, it can be set to 10cm-15cm according to the gap between the tilting table and the rewinding platform 7 or the rear platform 8. The baffle 4 is divided into upper and lower parts by the support plate 5. The width a of the upper end is 40cm and the width b of the lower end is 10cm. In actual application, according to the distance relationship with other surrounding equipment and the position of the support plate 5 on the baffle 4, the width a of the upper end of the baffle 4 is set to 30cm-40cm and the width b of the lower end is set to 10cm-20cm. The support block 6 is an inverted cone shape with an arc-shaped end face at the bottom. The maximum width of the support block 6 is the same as the width c of the support plate 5, and the height h is 15cm. The bottom of the support block 6 slightly exceeds the bottom of the baffle 4. In actual application, the height h of the support block 6 is set to 15cm to 25cm according to the lower width b of the baffle 4.

[0016] Before the improvement, the tilting table typically tilted towards the rewinding machine platform 7. A gap of approximately 45cm was always present between the tilting table and the rear platform 8, posing a risk of falls and injuries to workers. After the improvement, as... Figure 3As shown, when the tilting table flips towards the rewinding machine platform 7, a baffle 4 and a support plate 5 are installed on the side of the U-shaped workbench 3 near the rear platform 8. The support plate 5 is on the same plane as the rear platform 8, thus filling the gap between the tilting table and the rear platform 8 to prevent personnel from falling or paper from falling into the gap and increasing the difficulty of cleaning. At the same time, a support block 6 is installed at the bottom of the support plate 5 to ensure the safety of operators when working on the platform. After the paper is rewound, the tilting table receives the paper roll, removes the roll, and arranges it, as shown in the image. Figure 4 The tilting table, as shown, tilts to deliver the paper roll to the rear platform 8. At this time, a baffle 4 and a support plate 5 are also installed on the side of the U-shaped workbench 3 near the rewinding platform 7. The support plate 5 is on the same plane as the rewinding platform 7, thus filling the gap between the tilting table and the rewinding platform 7 to prevent personnel from falling or damaged paper from falling into the gap. Simultaneously, after the paper roll is delivered to the rear platform 8, the stop block on the rear platform 8 is lowered to deliver the paper roll to the next process. If the paper roll springs back, the baffle 4 replaces the side of the U-shaped workbench 3 to contact the paper roll, increasing the contact area and preventing the paper roll from being cut, thus avoiding the risk of damaged paper rolls needing to be remelted. An alarm device connected in series with the tilting table switch sounds an alarm when the tilting table tilts, alerting nearby workers to pay attention to safety.
