Description

Technical Field

[0001] This utility model relates to a rust-proof paper roll slitting device, specifically a rust-proof paper roll slitting device, belonging to the field of rust-proof paper rolls. Background Technology

[0002] Rust-preventive paper, also known as vapor phase corrosion inhibitor paper or VCI paper, is a rust-preventive packaging material made from packaging kraft paper as the base material and coated with a vapor phase corrosion inhibitor (VCI). It is widely used in the automotive, machinery, and electronics industries for anti-oxidation packaging of metal products. Its principle is that the VCI components vaporize in a sealed environment to form a protective film, blocking water and oxygen from contacting the metal, thus achieving rust protection for metal materials such as iron, copper, and alloys.

[0003] In traditional sheet production, the hub size of the winding device is usually fixed. This means that when producing sheets of different sizes, it is necessary to frequently change hubs of different sizes, which not only increases production costs but also reduces production efficiency.

The control system consists of a controller and counter installed on the machine body 1, as well as control and sensing devices such as sensors;

[0028] After adjusting the position of the limiting rod 32 using the adjusting rod 10, the threaded rod 4 can be manually turned.

A wire groove is opened at the corresponding position of the slider 34 relative to the wire rod, and the wire rod is slidably set in the wire groove.

An adjusting rod 10 is rotatably connected between the limiting rod 32 and the side wall of the adjusting ring 9.

[0030] Example 3, please refer to Figure 1 and Figure 5 Two stabilizer bars 11 are fixedly connected between the two mounting plates 6. A through-hole stabilizer is provided at the corresponding position of the threaded sleeve plate 8 relative to the stabilizer bar 11, and the threaded sleeve plate 8 is slidably sleeved on the outside of the stabilizer bar 11 through the stabilizer hole.

[0031] Example 4, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Two turntables 31 are fixedly connected by connecting rods 5 arranged in a circular array.

[0033] Example 6, please refer to Figure 1 A servo motor 2 14 is mounted on one side of the mounting plate 6, and the output shaft of the servo motor 2 14 is fixedly connected to one end of the bidirectional screw 7.

[0034] Specifically, both servo motor 214 and servo motor 12 are electrically connected to the controller, and the controller is electrically connected to the power supply. The models of servo motor 214 and servo motor 12 are not limited, and the appropriate equipment shall prevail.

[0037] Working principle:

[0038] The winding circumference is adjusted by changing the position of the limit rod 32 on the turntable 31 according to the required sheet size. The servo motor 14 is started to drive the bidirectional screw 7 to rotate. The bidirectional screw 7 then drives the two threaded sleeves 8 to move closer or further apart. The threaded sleeves 8, in turn, use the adjusting rod 10 to push the limit rod 32 to move, causing the slider 34 on the limit rod 32 to slide within the groove 33, thereby quickly adjusting the position of each limit rod 32. This changes the winding circumference, achieving stepless adjustment of the sheet production size.

[0039] The turntable 31 is driven to rotate by the servo motor 12, thereby using the contour assembly 3 to wind the sheet.
