Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printers, and in particular relates to a material collecting and releasing device of an inkjet printer. Background Art

[0002] Inkjet printers print images or text by spraying ink droplets onto the print medium through a nozzle. The quality of the machine's printing depends partly on the precision of the print carriage nozzle and partly on the speed at which the printing ink dries and the way the material is collected. The printing precision of the carriage can be achieved by configuring a high-precision nozzle, but the quality of the printing ink drying or drying directly affects the quality of the final product. Most of the existing material collection and release methods use a low-resistance follow-up with a light roller, but this method of collecting and releasing materials has the following problems: on the one hand, large amounts of ink are prone to deformation, and the rigid light roller cannot absorb uneven paper deformation well, resulting in wrinkles; on the other hand, the material is collected before the printing ink has dried or dried, resulting in scratches on the pattern and poor color development of the ink transfer. This method of collecting and releasing materials seriously affects the quality of the printed product.

[0003] In view of this, it is necessary to improve and provide a material collecting and releasing device for a large ink volume inkjet printer. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an improved material collection and unloading device for an inkjet printer to solve the problem that paper is easily deformed and wrinkled when printing with a large amount of ink, and is difficult to dry, resulting in poor quality of the printed product.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A paper-retracting and unreeling device for an inkjet printer comprises a frame, a paper-reeling shaft, a paper-reeling swing rod, a material-feeding guide roller, a printing platform, a material-discharging guide roller, a paper-collecting swing rod, a banner roller, a paper-collecting shaft, a first infrared drying device, a second infrared drying device, and a third infrared drying device. Side panels are provided on both sides of the frame. The paper-reeling shaft, the paper-reeling swing rod, the paper-collecting swing rod, the banner roller, and the paper-collecting shaft are all arranged between the side panels on both sides of the frame. The first infrared drying device is arranged between the material-discharging guide roller and the paper-collecting swing rod, the second infrared drying device is arranged between the paper-collecting swing rod and the banner roller, and the third infrared drying device is arranged between the banner roller and the paper-collecting shaft.

[0007] Furthermore, the paper-releasing swing arm and the paper-collecting swing arm are composed of a support shaft, two side brackets, and a swing shaft. Both ends of the support shaft are respectively fixed on the side plates on both sides of the frame. The paper-releasing swing arm is arranged at a corresponding position below the feed guide roller, and the paper-collecting swing arm is arranged at a corresponding position below the discharge guide roller.

[0008] Furthermore, a paper placing motor is installed on a side plate on one side of the frame, and the paper placing motor is connected to the paper placing shaft.

[0009] Furthermore, a paper collecting motor is installed on a side plate on one side of the frame, and the paper collecting motor is connected to the paper collecting shaft.

[0010] Furthermore, a bottom beam is provided below the printing platform, the bottom beam is mounted on the frame, and the feed guide roller and the discharge guide roller are mounted on the bottom beam and are respectively located on both sides of the printing platform.

[0011] Furthermore, the first infrared drying device includes an infrared drying box, and mounting brackets are provided at both ends of the infrared drying box, and the mounting brackets are connected to the side panels on both sides of the frame. The infrared drying box is parallel to the paper passing between the discharge guide roller and the paper collection rocker.

[0012] Furthermore, a plurality of rollers are provided at the bottom of the second infrared drying device, which are arranged below the paper passing between the paper receiving swing rod and the banner roller and between the side plates on both sides of the frame.

[0013] Furthermore, two ends of the third infrared drying device are connected to the side panels on both sides of the frame and are located below the paper receiving shaft.

[0014] Furthermore, at least two feet and at least two universal wheels are provided at the bottom of the side panel.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) Three infrared drying devices are set at the paper receiving end. The first infrared drying device quickly dries the wet ink, the second infrared drying device basically dries the moisture absorbed by the paper, and the third infrared drying device ensures that the paper is completely dried, solving the problem that a single infrared drying device is difficult to dry when printing a large amount of ink.

[0017] (2) Rocker bars are provided at the paper feeding end and the paper receiving end to flatten the paper and ensure the stability of the tension of the paper. The double rocker bar structure can effectively alleviate the tension fluctuation of the paper, thus solving the problem of excessive fluctuation of the tension of the paper during printing in the traditional paper feeding and receiving device.

[0018] (3) An elastic banner roller is set at the paper receiving end to ensure that the paper is not easily wrinkled when it is rolled up. BRIEF DESCRIPTION OF THE DRAWINGS
