Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a slitting device for an indicator. Background Technology

[0002] In machining processes, common cutting methods include manual cutting, semi-automatic cutting machine cutting, and CNC cutting machine cutting. Manual cutting is flexible and convenient, but it suffers from poor quality, large dimensional errors, significant material waste, and a large workload for subsequent processing. It also involves harsh working conditions and low production efficiency. Among semi-automatic cutting machines, contour cutting machines produce relatively high-quality cuts, but due to the use of cutting molds, they are not suitable for single-piece, small-batch, or large workpiece cutting. Other types of semi-automatic cutting machines, while reducing the labor intensity of workers, have simple functions and are only suitable for cutting parts with relatively regular shapes.

[0003] For example, the Chinese authorized patent with announcement number CN220364778U, entitled "(A Fabric Cutting and Slitting Device)," includes: a frame, a cutting assembly, and a lifting assembly. The cutting assembly is equipped with a cutting blade holder, a drive structure, a rotating shaft structure, and a cutting tool structure. The cutting blade holder is mounted on the frame, the drive structure is mounted on the cutting blade holder, the rotating shaft structure is rotatably mounted on the cutting blade holder and connected to the drive structure, and the cutting tool structure is mounted on the rotating shaft structure. The frame is provided with a cutting groove structure that cooperates with the cutting tool structure. The lifting assembly is mounted on the frame and connected to the cutting blade holder, and is used to drive the cutting blade holder to move up and down. This utility model has a simple structure and reasonable design. During cutting and slitting, the lifting assembly controls the lifting of the cutting blade holder, and the drive structure drives the rotating shaft structure to rotate, thereby causing the cutting tool structure to rotate and cut, so as to cut the incoming fabric into the required small strips of fabric with openings, achieving high-precision and high-efficiency cutting and slitting for subsequent processing.

[0004] However, existing methods for slitting indicator material rolls suffer from the problem that adsorbed impurities on the rollers can damage the cutting blades during the slitting process; therefore, they do not meet the current requirements. To address this, we propose a slitting device for indicators. Utility Model Content

[0028] Example 2

[0029] Please see Figure 1 and Figure 3 A first roller 200 is provided between two first mounting plates 101. A first gear 201 is provided on the outside of both ends of the first roller 200. A first semicircular cover 202 and a second semicircular cover 20201 are provided on the outer wall of the first roller 200. The first semicircular cover 202 and the second semicircular cover 20201 wrap the first roller 200 and are connected by bolts.

[0030] The first semicircular cover 202 and the second semicircular cover 20201 can be installed and disassembled separately and then threadedly assembled on the first roller shaft 200.

[0031] Please see Figure 1 The lower end face of the external connecting rod 303 is provided with a second mounting plate 301, and there are two second mounting plates 301. A second roller shaft 300 is provided between the two second mounting plates 301. A second gear 302 is provided on the outside of both ends of the second roller shaft 300. The second gear 302 is meshed with the first gear 201.

[0032] The second gear 302 meshes with the first gear 201, which can make the first roller shaft 200 rotate synchronously with the second roller shaft 300.

[0033] Please see Figure 1 The outer wall of the second roller 300 is provided with a third semicircular cover 304 and a fourth semicircular cover 30401, which wrap around the second roller 300. A cutting blade 30402 is provided around the outer wall of the third semicircular cover 304 and the fourth semicircular cover 30401, and the cutting blade 30402 is welded to the third semicircular cover 304 and the fourth semicircular cover 30401.

[0034] The cutting blade 30402 can effectively slit materials. The third semicircular cover 304 and the fourth semicircular cover 30401 can be installed and disassembled separately and then threaded together on the second roller shaft 300.

[0035] Please see Figure 1 One of the two second mounting plates 301 has a motor 102 on its outer wall. The motor 102 is rotatably connected to the second roller shaft 300.

[0036] The recessed cavity 20202 provides an inner groove for the cutting blade 30402 during use, preventing hard contact between components.

[0037] Working principle: The mounting base plate 100 is installed on the conveying device. When the externally conveyed material needs to be cut, the second mounting plate 301 connects the second gear 302 with the first gear 301 through the external connecting rod 303. At the same time, the second mounting plate 301 is installed on the upper surface of the first mounting plate 101. When the slitting operation is started, the first semicircular cover 202 and the second semicircular cover 20201, along with the third semicircular cover 304 and the fourth semicircular cover, enclose the first roller shaft 200 and the second roller shaft 300. A set is formed by one first semicircular cover 202, one second semicircular cover 20201, one third semicircular cover 304, and one fourth semicircular cover 30401. The motor 102 is turned on to drive the first roller shaft 200 to rotate, and the synchronous belt... The first gear 201 is driven, which in turn drives the second gear 302, which in turn drives the second roller shaft 300 to rotate. This allows the cutting blade 30402 to cut strips by using the concave cavity 20202 inside the first semicircular cover 202 and the second semicircular cover 20201 to provide an inner groove for the cutting blade 30402. The position of the corresponding adjusting connecting plate 105 below each set of the first semicircular cover 202 and the second semicircular cover 20201 can be adjusted by the pulley 107 in the second built-in moving groove 103, thereby placing the scraper 106 against the outer wall of the first semicircular cover 202 and the second semicircular cover 20201. The cut strips are then conveyed by the conveying device.
