Problems solved by technology

[0003] The surface of disposable paper cups is also formed by printing. Because paper cups need to hold water, they need to have good water resistance. At present, most of the paper cups on the market achieve the corresponding waterproof purpose by setting a PE layer on the paper cups. In the actual production process, printing is required. And adding two links of PE layer to achieve, and it needs to be carried out on two different equipment, there is a problem of low production efficiency

Embodiment 1

[0043] refer to figure 1, a kind of flexo printing equipment includes a strip-shaped body 1, and an unwinding mechanism 2 is arranged at the head end of the body 1, a winding mechanism 3 is arranged at the end of the body 1, and a winding mechanism 3 is arranged in the middle of the body 1 along the conveying direction Coating mechanism 4, drying mechanism 6 and printing mechanism 5, wherein coating mechanism 4 is used for coating degradable plastic layer; Wherein unwinding mechanism 2 comprises the unwinding roller 21 that is rotatably connected on the body 1, and rewinding mechanism 3 comprises rotatably connected The winding roller 31 on the body 1, and the drive motor (not shown in the figure) that drives the winding roller 31 to rotate is arranged on the body 1, so that the winding and unwinding can be realized by the rotation of the winding roller 31 The roller 21 is continuously discharging, and the paper tape passes through the coating mechanism 4, the drying mechanism...

Embodiment 2

[0051] refer to Figure 4 , a kind of flexo printing equipment, its main difference from Embodiment 1 lies in the difference of the drying mechanism 6, in this embodiment, the second pulling roller 72 is located on the top outside the box body 61, and the third pulling roller 73 is located on the top outside the box body 61 At the bottom, the middle part of the box body 61 is provided with a partition 67 to form an upper chamber 65 and a lower chamber 66. The first traction roller 71 is located in the upper chamber 65, and the partition 67 is provided with a perforation 68, and the infrared heating tube 62 is arranged on the upper chamber. On the opposite inner wall of the cavity 65; on the opposite side wall of the box body 61 corresponding to the lower cavity 66, there is a slot 69 for the paper tape to pass through, so that the paper tape penetrates into the box body 61 and first passes through the upper cavity 65 to achieve the first drying and curing , then pass through t...

Embodiment 3

[0053] Such as Figure 5 As shown, a flexographic printing equipment differs from Embodiment 1 in that the traction mechanism includes a fourth traction roller 81 and a fifth traction roller 82, and the fourth traction roller 81 and the fifth traction roller 82 are both Rotationally connected on the machine body 1, the fourth traction roller 81 is positioned obliquely above the coating roller 42, that is, the fourth traction roller 81 is higher than the coating roller 42, and the fifth traction roller 82 is arranged at the bottom of the corresponding body 1, so that after coating The paper tape of the cover roller 42 will be continuously conveyed obliquely for a certain distance, and the machine body 1 is also provided with a drying mechanism 6 at the corresponding distance. The drying mechanism 6 includes an infrared heating tube 62 and is located near the paper tape coated with a degradable plastic layer. On one side of the degradable plastic layer, the degradable plastic la...

Abstract

The invention relates to flexographic printing equipment. The flexographic printing equipment comprises a body and an unwinding mechanism, a printing mechanism and a winding mechanism which are sequentially arranged, wherein a coating mechanism for coating a degradable plastic layer is arranged between the unwinding mechanism and the printing mechanism, the coating mechanism comprises a conveyingroller, a coating roller and a supporting roller rotationally connected on the body, the conveying roller abuts against the coating roller, a gap allowing paper tapes to pass through is formed betweenthe coating roller and the supporting roller, and a drying mechanism is arranged between the coating mechanism and the printing mechanism. The coating mechanism and the drying mechanism are arrangedon the body, the coating mechanism coats the surface of the paper tape with the degradable plastic layer to improve the waterproof performance of the paper tape, the drying mechanism timely dries thepaper tape, and the continuously conveyed paper tape is subjected to surface printing by the printing mechanism and finally wound well, so that coating of the degradable plastic layer and coating canbe completed on the degradable plastic layer on the surface of the paper tape through one device, the production is simplified effectively, and the space of a plant occupied by the equipment can be effectively reduced while the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of printing equipment, in particular to a flexographic printing equipment. Background technique [0002] The flexographic printing machine uses fluid ink with strong fluidity. The ink is transferred to the graphic part of the printing plate by the ink fountain rubber roller and the anilox transfer roller to make it inked, and then the printing pressure is applied by the pressing roller to transfer the printing plate The ink on the surface is transferred to the substrate, and finally the printing process is completed on the dry side. [0003] The surface of disposable paper cups is also formed by printing. Because paper cups need to hold water, they need to have good water resistance. At present, most of the paper cups on the market achieve the corresponding waterproof purpose by setting a PE layer on the paper cups. In the actual production process, printing is required. And it needs to be realized by addin...
