Abstract

The utility model relates to a roller cutting mechanism with cutters, which comprises an upper roller shaft, a lower roller shaft, a circular blade, a common sleeve, a stepped sleeve and a fixed key. The specific structure and connection method are as follows: the upper roller is alternately covered with ordinary sleeves and annular blades, the ordinary sleeves and annular blades are interspersed on the upper roller through fixed keys, the lower roller is covered with several stepped sleeves, and the adjacent steps A sipe gap is formed between the sleeves, and a small part of the annular blade on the upper roller just submerges in the sipe gap formed by the stepped sleeve. Adopting the present invention can form different intervals by replacing common sleeves and stepped sleeves of different specifications, and can cut articles into strips of different widths.

Description

A roller cutting mechanism with group knives

technical field

The invention relates to the field of cutting tools for strips, in particular to a roller cutting mechanism with group knives.

Background technique

In many industries, it is necessary to cut plate-shaped items into strip-shaped items for subsequent use, and cutting devices play an indispensable role in it. There are many kinds of cutting tools on the market, but there are not many cutting tools that can adjust the cutting width, and the abnormal wear and tear of the tools is also common.

Contents of the invention

The object of the present invention is to provide a roller cutting mechanism with group knives, which solves the problem of adjustable cutting width and effectively prevents abnormal wear of the knives.

The technical solution adopted by the present invention is: a cutter group roller cutting mechanism, including an upper roller, a lower roller, an annular blade, a common sleeve, a stepped sleeve and a fixed key. The specific structure and connection method are as follows: the upper roller is alternately covered with ordinary sleeves and annular blades, the ordinary sleeves and annular blades are interspersed on the upper roller through fixed keys, and the lower roller is covered with several stepped sleeves. A sipe gap is formed between the sleeves, and a small part of the annular blade on the upper roller just submerges in the sipe gap formed by the stepped sleeve.

The common sleeve, the annular blade and the stepped sleeve are connected with the roller shaft through a fixed key.

The gap between the sipes formed between the stepped sleeves is 5 mm.

The common sleeve and the stepped sleeve are used as a set, and the total length of each set of stepped sleeve is equal to the length of the common sleeve plus the thickness of the blade plus 2 to 3 millimeters.

The outstanding technical effect of the present invention is:

1. By replacing the ordinary sleeve on the upper roller and the stepped sleeve on the lower roller, the ring blade can be kept at the required distance, so as to obtain different cutting widths.

2. The gap formed by the stepped sleeve on the lower roller just accommodates the rotating circular blade to avoid its abnormal wear and protect the cutter.

3. The ring blade and the ordinary sleeve are combined with the upper roller through the positioning key, so that the ordinary sleeve and the ring blade can be easily removed from the upper roller for replacement.

Detailed ways

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

The knife group roller cutting mechanism of the present invention comprises an upper roller 8, a lower roller 11, an annular blade 5, a common sleeve 6, a stepped sleeve 10 and a fixed key 7, and the specific structure and connection mode are: an upper roller Ordinary sleeves 6 and annular blades 5 are alternately sleeved on the shaft 8, and the ordinary sleeves 6 and annular blades 5 are interspersed on the upper roller 8 through the fixed key 7, and the lower roller 11 is covered with several stepped sleeves 10, adjacent steps A sipe gap 9 is formed between the sleeves 11 ; the annular blade 5 on the upper roller 8 just submerges in a small part into the sipe gap 9 formed by the stepped sleeve 10 .

Working principle and process:

As shown in Figure 1, Figure 2 and Figure 3, the upper roller 8 and the lower roller 11 are meshed through the gear 1 and the gear 2, so that the power is transmitted to the upper roller 8 through the lower roller 11, and the upper roller 8 has The rolling bearing support seat 3 is supported to increase the stability of the transmission; the annular blade 5 and the ordinary sleeve 6 are combined with the upper roller 8 through the fixed key 7, and the lower roller 11 is covered with a stepped sleeve 10, and the adjacent stepped sleeve 10 Form the sipe gap 9 of about 5 millimeters, make the annular blade 5 on the upper roller 8 just a small part submerge in the sipe gap 9, form the protection to the annular blade.

As shown in Figure 3 and Figure 4, according to actual needs, by replacing the ordinary sleeve 6 on the upper roller 8 and the stepped sleeve 11 on the lower roller 11, the cutting width can be changed to achieve the requirements of cutting with different widths.
