Description

Technical Field

[0001] The utility model relates to the technical field of digital printing processing, in particular to a drying device for a digital printing machine. Background Technique

[0002] Digital inkjet printing has been widely used in the digital textile printing industry. Digital inkjet printing requires the use of a digital printing machine. During the printing process, the digital printing machine performs printing and dyeing by means of inkjet, and there is no need to directly contact the item during this process, so as to ensure the integrity of the printed item and prevent the item from being deformed due to heat and pressure. The digital printing machine uses the direct output printing method of the computer and does not require any preparatory printing work in the early stage, which is convenient and fast. In order to ensure the drying of the product after processing and avoid the pattern from becoming distorted during storage, etc., and to ensure the quality of the printing, a drying device is needed to dry it.

[0003] However, the existing drying devices have certain defects in actual use. During printing processing, most of them perform drying operations on continuously printed products. When drying a single printed product, it cannot be positioned and fixed during drying. Therefore, when using hot air, etc. for drying, it is easy to cause it to move or even flip, which will affect the drying effect and may also cause the printed pattern to become distorted, affecting the quality of the product. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drying device for a digital printing machine to solve the problems raised in the above background technique.

A drying hood is arranged at one end of the digital printing machine main body. A drying component is arranged inside the drying hood. Empty slots are symmetrically opened at both ends of the drying hood. Transverse plates are symmetrically arranged on both sides inside the drying hood. Lifting components are equidistantly arranged under the transverse plates. A guiding component and a positioning component are arranged under the lifting components, and the guiding component and the positioning component are arranged alternately.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A drying device for a digital printing machine includes a processing table 1 for printing and processing fabrics, etc., in which a conveying device 2 (which can be a conveyor belt, convenient for conveying fabrics, etc., facilitating printing and drying operations, a relatively mature technology, not elaborated here) is installed. And on both sides of the conveying device 2 on the processing table 1, mounting plates 4 of the adjusting component are symmetrically installed. On the mounting plate 4, a mounting plate 4 is also installed through a hydraulic telescopic rod 5, and the mounting plate 4 at its top is fixedly connected to the digital printing machine main body 3 (a relatively mature technology, not elaborated here) (can be fixedly connected by bolts).

[0023] Please refer to Figures 1-5, and in order to be able to dry after printing to facilitate subsequent processing or storage operations, a drying hood 6 is installed at the rear end of the processing table 1 of the digital printing machine main body 3. Empty slots 9 that do not affect the passage of the product are provided at both ends of the drying hood 6. A hot air blower 8 of the drying component is installed at its top end, and the output end is connected to a connecting pipe 13, which penetrates the drying hood 6 and extends to the inside to be provided with an air outlet pipe 14. A plurality of groups of drying ports 15 are equidistantly and obliquely arranged on the side wall of the air outlet pipe 14, which can be four, five or six groups, etc., to ensure the drying effect. In order to assist drying, a heating device 10 (which can be a heating rod, using the resistance heating method, or other heating equipment, a relatively mature technology, will not be elaborated here) is installed at the top end inside the drying hood 6, which can perform heating-assisted drying. And an exhaust pipe 7 is provided on the side wall of the drying hood 6 to facilitate the discharge of the dried gas, which is connected to a purification device (not shown in the figure), and can purify harmful substances and the like during the drying process and then discharge them to ensure safety.

[0024] Please refer to Figures 1-5 , on both sides inside the drying hood 6, horizontal plates 11 are symmetrically welded. And four groups of electric push rods 17 of the lifting components are equidistantly arranged under the corresponding horizontal plates 11. The top ends are fixedly connected to the horizontal plates 11 through connecting pieces 16, and the bottom ends are fixedly connected to the lifting plates 12 of the guiding component and the positioning component through connecting pieces 16. The guiding component and the positioning component are staggered. For the connecting piece 16, it can be rotatable or non-rotatable, and is set according to the actual situation. And the guiding component includes guiding rollers 18 arranged under the lifting plate 12, which is applicable to continuous fabric printing processing, and can perform guiding and pressing during drying. And a pressing plate 19 of the positioning component is welded under the adjacent lifting plate 12, and an anti-slip pad 20 is bonded to its bottom end, which can be adapted to the pressing and positioning during the drying of a single piece of fabric or paper for printing.

[0025] Working principle: When the utility model is in use, when printing and processing the product, the hydraulic telescopic rod 5 can be extended and retracted to drive the digital printing machine main body 3 to move up and down, adjusting the height between it and the product to facilitate printing and processing. Then it moves into the drying hood 6 through the empty slot 9. And when it is a continuous product, the electric push rod 17 can be extended to drive the lifting plate 12 on the guiding roller 18 to move down, which can contact both sides of the product to perform pressing and guiding. And through the operation of the hot air blower 8, the dry hot air is blown out through the drying ports 15 on the connecting pipe 13 and the air outlet pipe 14. At the same time, the heating device 10 works to assist the drying operation. The dried gas is discharged through the exhaust pipe 7. And when drying a single piece of product, when the product moves to directly below the drying hood 6, the electric push rod 17 on the pressing plate 19 is extended to drive it to move down, and the anti-slip pad 20 can be used to press and position the product. Then the hot air blower 8 and the heating device 10 work for drying operation. After completion, the electric push rod 17 contracts and resets, which can facilitate subsequent processing or storage operations.
