Problems solved by technology

However, since the relative position cannot be determined when bonding materials, this mechanism can meet the requirements of use when bonding materials without patterns, but it cannot satisfy the alignment of the two material patterns after bonding materials when bonding materials with patterns. As a result, the pattern of the produced product cannot be fixed at the required position of the product, resulting in waste products, and it is difficult to adapt to market demand

Embodiment 1

[0044] In this embodiment, a method for positioning and splicing patterned sheets comprises the following steps:

[0045] (1) Position the spare material and the used material first, so that the pattern on the spare material is aligned with the pattern on the used material;

[0046] Among them, the method for positioning the spare material is: set the positioning alignment marking line on the waste material extraction mechanism of the spare material and the conveying mechanism of the used material respectively, and use the pattern of the spare material at the positioning alignment marking line as the mark point, When the same pattern as the marked point on the used material is sent to the positioning alignment line of the used material, the pattern on the spare material is aligned with the pattern on the used material;

[0047] (2) Separately cut off the spare material and the used material to form aligned incisions;

[0048] Among them, before the spare material and the used...

Embodiment 2

[0053] In this embodiment, a device for positioning and splicing patterned sheets that can realize the method described in Embodiment 1 includes an unwinding mechanism, a lower clamping mechanism, an upper clamping mechanism, a shearing and fixing mechanism, a waste material extraction mechanism, and a left pattern The positioning target and the right pattern positioning target, the upper clamping mechanism, the shearing fixing mechanism and the lower clamping mechanism are arranged in sequence between the unwinding mechanism and the waste material extraction mechanism, and the left pattern positioning target is set on the left side of the waste material extraction mechanism , the right pattern positioning target plate is set on the right side of the waste material extraction mechanism.

[0054] Such as Figure 3-9 As shown, the unwinding mechanism includes a left unwinding shaft and a right unwinding shaft, and the left unwinding shaft and the right unwinding shaft alternatel...

Abstract

The invention discloses a positioning splicing method and device for sheets with patterns. The method comprises the following steps: firstly, positioning a standby material and a used material to enable the patterns of the standby material and the used material to be aligned, then, cutting off the standby material and the used material respectively to form aligned cutting openings, and connecting the materials at the cutting openings through sticking a transparent adhesive tape. The device comprises an unreeling mechanism, a lower clamping mechanism, an upper clamping mechanism, a shearing fixing mechanism, a waste separation mechanism, a left pattern positioning standard-board and a right pattern positioning standard-board, wherein the upper clamping mechanism, the shearing fixing mechanism and the lower clamping mechanism are sequentially distributed between the unreeling mechanism and the waste separation mechanism; the left pattern positioning standard-boar and the right pattern positioning standard-boar are respectively arranged on the left side and the right side of the waste separation mechanism. The process method disclosed by the invention is simple in principle, good in splicing effect, particularly suitable for the positioning splicing process of the sheets with the patterns, low in rejection rate, and suitable for high-speed high-yield production of products, better meets market demands and the device can realize seamless positioning non-waste splicing of the sheets with the patterns.

Description

technical field [0001] The invention relates to the technical field of sheet splicing, in particular to a method and device for positioning and splicing patterned sheets. Background technique [0002] Disposable hygiene products such as sanitary napkins and panty liners, as well as equipment such as plaster packaging, have a common feature, that is, most of the raw materials used in the production of these equipment are sheet-shaped coils, and often need 24-hour continuous operation. Since the existing similar equipment has required that the machine can replace the coil without stopping the machine to meet the efficient and stable operation of the equipment. However, as the market's requirements for products increase, more and more materials are continuously and evenly printed with beautiful patterns on the materials, or evenly printed with color barcodes for machine inspection, etc., which are patterned sheet materials. . [0003] The existing material splicing process is...
