Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of printing equipment, and particularly relates to a continuous printing machine for sandwich mesh materials. Background Art
[0002] The sandwich mesh material is composed of sandwich mesh cloth and polymer thin films adhered to both sides thereof, and has good corrosion resistance, wear resistance and bending resistance. At the same time, it also has advantages such as waterproof and anti-ultraviolet, and can be used for preparing outdoor luggage, tents and the like. According to the requirements of different products, various patterns need to be printed on the sandwich mesh material. For some patterns, such as trademarks, logos, etc., the printing requirements are very strict, and printing needs to be carried out strictly in accordance with the design drawings. However, the sandwich mesh material is relatively hard, and when printing with the common continuous printing machines on the market at present, problems such as misregistration and running of the plate are likely to occur during multi-plate printing. Since the sandwich mesh material is a rolled material, once misregistration and running of the plate occur during continuous printing, it will cause the scrapping of a large area or even the entire roll of sandwich mesh material, undoubtedly resulting in a waste of resources and an increase in production costs. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a continuous printing machine for sandwich mesh materials that can perform continuous printing without misregistration and running of the plate.

[0024] To describe in detail the technical content, achieved objectives, and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.
[0025] Please refer toFigures 1 to 3 , a continuous printing machine for sandwich mesh materials, comprising a calendering device, a tension adjusting device and a printing mechanism which are arranged in a production line in sequence;
[0026] The tension adjusting device includes a moving device and a top roller. The moving device is used to drive the top roller to approach or move away from the sandwich mesh material in transmission.
[0027] As can be seen from the above description, the beneficial effects of the present utility model are as follows: At present, most sandwich mesh materials are processed by a film printing machine, that is, patterns are first printed on the film, and then the patterns are bonded to the sandwich mesh cloth. However, due to stretching deformation during the bonding process of the film and the sandwich mesh cloth, this method and related equipment cannot be used for patterns that are prone to showing deformation. Moreover, traditional continuous printing machines have problems such as easy printing plate misalignment and poor printing effects. By providing a new continuous printing machine and applying it to sandwich mesh materials, by arranging a calendering device and a tension adjusting device in front of the printing mechanism, it can be ensured that the sandwich mesh material is completely flat and not overly stretched when it is transmitted to the printing machine, thereby avoiding the problems of printing plate running and misalignment of the printed pattern compared with the designed pattern, and improving the yield of the product.
[0028] Among them, the moving device includes two linear guide rails. The linear guide rail includes a slide rail and a slider connected in a sliding manner; the top roller includes a roller shaft and a roller body sleeved on the roller shaft. Both ends of the roller shaft are respectively connected to a slider. By driving the slider to reciprocate along the slide rail through a motor, the top roller is driven to approach or move away from the sandwich mesh material in transmission. The structure of the moving device is not limited to the linear guide rail, and can also be an electric push rod, a ball screw linear motion mechanism, etc., as long as the movement of the top roller can be achieved.
[0029] Referring to Figure 3 as shown, among them, it includes at least two printing mechanisms arranged in sequence, and a tension adjusting device is arranged between the printing mechanisms, that is, multiple sets of the structures within the dotted square boxes in Figure 3 are continuously arranged. For example, it includes a calendering device, a first tension adjusting device, a first printing mechanism, a second tension adjusting device, a second printing mechanism, a third tension adjusting device, a third printing mechanism, a fourth tension adjusting device, a fourth printing mechanism, a fifth tension adjusting device, and a fifth printing mechanism arranged in sequence.
[0030] As can be seen from the above description, according to different requirements, the patterns vary greatly, and multiple multi-color printings are often required to form the final pattern. Therefore, more than one printing mechanism can be set, and a tension adjusting device is added between two printing mechanisms, which can make the material in transmission relax or tighten slightly, ensure that it is completely flat but not overly stretched when entering the next printing mechanism, thereby ensuring accurate alignment and avoiding problems such as printing plate misalignment and running.
[0031] Among them, it also includes a winding device arranged after the printing mechanism, which is used to wind the printed material for subsequent packaging and transportation.
[0032] Among them, the printing mechanism includes a printing device and a drying device arranged in sequence. The printing is ink printing, and it needs to be dried after printing before entering the next process to avoid problems such as ink sticking to the rollers when the ink is not completely dry.
[0033] Among them, the printing device includes a rubber roller, an impression roller, and an ink tank arranged in sequence from top to bottom. The wire mesh material passes between the rubber roller and the impression roller. During the rotation of the impression roller, it dips ink from the ink tank and prints on the material. To avoid excessive ink dipping on the impression roller, a scraper can be set on one side of the impression roller to scrape off the excess ink.
[0034] Among them, the drying device is a vertical oven or a tunnel furnace. This type of assembly line oven can provide a longer drying stroke. During the drying process, the ink is dried, and at the same time, the wire mesh material will be slightly softened, which is beneficial for the subsequent tension adjustment device to further flatten it, ensuring that the subsequent printed pattern will not deviate from the previous printing and there will be no problems such as misregistration or running of the plate. The drying temperature is 90 - 130 °C, and the specific temperature can be adjusted according to the type of ink and the situation of the printed pattern, but the temperature cannot be too low to ensure that it can play a role in softening the wire mesh material. The drying time is generally 8 - 15 s.
[0035] Among them, the ironing device includes a first hot roller, a second hot roller, a first cold roller, and a second cold roller arranged in sequence. The temperatures of the first hot roller and the second hot roller are 80 - 120 °C. By first using the hot roller for high-temperature ironing to soften the wire mesh material, then using the cold roller to cool and flatten it, and cooperating with the subsequent tension adjustment device for adjustment, it is flat and without deformation when entering the printing mechanism.
