High precision slitting equipment and slitting knife jig thereof

Abstract

The invention relates to high precision slitting equipment and a slitting knife jig thereof. The slitting knife jig comprises a large die, a fixing shaft and a small die, wherein the large die comprises a left side plate, a right side plate and a base plate connected between the left side plate and the right side plate; the fixing shaft is arranged between the left side plate and the right side plate of the large die; the small die is arranged on the large die through the fixing shaft and comprises a lower die and an upper die; the fixing shaft is arranged on the lower die in a penetrating manner; the upper die is connected onto the lower die and comprises an outer frame, a plurality of positioning blocks arranged in the outer frame side by side in the left-right direction and a slitting knife blade tightly clamped between every two adjacent positioning blocks; the slitting knife blades extend into the lower die. According to the high precision slitting equipment and the slitting knife jig thereof, a printing material can be cut into strips having various predetermined widths according to requirements, and precision slitting is realized.

Description

technical field [0001] The invention relates to a high-precision slitting device and a slitting knife fixture. Background technique [0002] At present, in the printing industry, many products need to use small-sized self-adhesive materials. For example, when the battery is packaged with aluminum-plastic film, the edge of the product should be sealed with a small-width double-sided adhesive label. The labels are usually in the shape of a long strip without spacing, and are wrapped around the battery to prevent the battery from spontaneously igniting and play a role of safety protection. When making these labels, it is necessary to cut the material by means of a slitting device to form a predetermined width. [0003] Conventional slitting equipment is provided with two circular slitting blades, and these slitting blades are located on both sides of the base, and the material passes through the base and is cut by the slitting knives on both sides to form a predetermined widt...

AI Technical Summary

Problems solved by technology

The defect of this kind of slitting equipment is: the thickness of the slitting blade is relatively thick, up to about 11mm, and the processing tolerance is relatively large. When slitting the material, the slitting width can only be carried out in multiples of 5mm, and the slitting The minimum width is 15mm

With the development of the label market, this has been unable to meet the size requirements of customers for labels
