Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a protective mechanism of a slitting machine. Background Art

[0002] Slitting machines are divided into multiple application fields. Paper tube slitting machines have many advantages. They are also called roll paper slitting machines. They are suitable for cutting various paper tubes with short lengths and high output. The paper tubes produced by paper tube slitting machines are used in various industries, including tubes for chemical fiber industry, film industry, printing industry, papermaking industry, leather industry, food packaging, construction industry, exhibition industry, etc.

[0003] When the existing slitting machine is in use, the cutting head will fit against the surface of the paper tube, and slitting is performed by rotating the paper tube and the cutter head. However, the cutter head of the slitting machine is generally exposed to the outside, which easily increases the danger of use during the operation of the cutting head. Therefore, we propose a protective mechanism for the slitting machine to solve the above problem. Utility Model Content

[0025] Further, see Figure 2 and Figure 3 It can be known that the driving mechanism 6 includes a pushing cylinder 61, and the pushing cylinder 61 is installed above the limit frame 5, and the end of the pushing cylinder 61 passes through the limit frame 5 and is connected to a driving cross bar 62, both ends of the driving cross bar 62 are fixedly connected to connecting rods 63, and the bottom of the connecting rod 63 is fixedly connected to a connecting baffle rod 64, and the bottom of the connecting baffle rod 64 is fixedly connected to an installation cross bar 65. By pushing the cylinder 61, the driving cross bar 62 can drive multiple groups of connecting baffle rods 64 and the installation cross bar 65 to move synchronously through the connecting rod 63.

[0026] Further, see Figure 2 and Figure 3It can be known that the cross-section of the driving cross bar 62 is set to be rectangular, and strip through grooves compatible with the driving cross bar 62 are opened on both sides of the limit frame 5. Through the strip through grooves opened on both sides of the limit frame 5, the driving cross bar 62 can move along the strip through grooves, thereby playing the role of limiting the driving cross bar 62.

[0027] Further, see Figure 3 and Figure 4 It can be known that multiple groups of connecting baffle rods 64 are arranged at equal distances between the connecting rod 63 and the mounting cross bar 65, and the lengths of the multiple groups of connecting baffle rods 64 are the same as the surface height of the fixed cover 4. By arranging multiple groups of connecting baffle rods 64 at equal distances, it is convenient to block both sides of the fixed cover 4.

[0028] Further, see Figure 3 and Figure 4 It can be known that the protective mechanism 7 includes a mounting bolt 71, the mounting bolt 71 is inserted into the inside of the mounting cross bar 65, and the mounting bolt 71 is threadedly connected to the protective side plate 72, the inner side of the mounting bolt 71 is connected to a connecting block 73 through the mounting bolt 71, and the end of the connecting block 73 away from the protective side plate 72 is fixedly connected to the protective front plate 74, and the protective side plate 72 can be connected to the protective front plate 74 by passing the mounting bolt 71 through the protective side plate 72 and the connecting block 73.

At this time, the installation cross bar 65 can make the protective side plate 72 drive the protective front plate 74 to move synchronously through the connecting block 73, so that when the slitting cutter head 3 is in use, the protective side plate 72 and the protective front plate 74 can be used to shield the outer side of the slitting cutter head 3 to reduce the use of dangerous objects, and when the slitting cutter head 3 is not in use, the push cylinder 61 can drive the cross bar 62 to reset, so that the connecting rod 63 and the connecting baffle rod 64 can pull the protective side plate 72 and the protective front plate 74 to reset;
