Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, in particular to a dust removal device for screen printing machines. Background Art

[0002] A flat screen printing machine is a type of printing machine. It is a machine that mainly prints text and images on the surface of flat profiles. It is a general term for machines or equipment used to produce printed products. When it comes to flat profiles, it is necessary to remove dust from the surface of the profiles to improve the printing quality. Modern screen printing processes are mostly integrated printing, that is, loading, dust removal, drying, and unloading are integrated. During the dust removal process, it is necessary to ensure that the position of the printed matter is accurate. In this way, after the dust removal is completed, when it flows directly to the printing process, printing deviation can be avoided. Existing screen printing machines use dust removal devices.

[0003] For example, a dust removal device for a screen printing machine is disclosed in the utility model patent with the announcement number CN215321321U. When removing dust, the printed matter needs to be self-centered and fixed before the surface of the glass cover plate can be dusted by a cleaning roller. After the dust removal is completed, the cleaning roller cleans the surface of the cleaning roller through a sleeve ring and an annular scraper. Such operation is not conducive to efficient printing on the assembly line of the screen printing machine. Based on this, a dust removal device for a screen printing machine is proposed.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 4 A dust removal device for a screen printing machine in this embodiment includes two track plates 1. The dust removal device for a screen printing machine can be directly connected to the assembly line of the screen printing machine. Two limiting rollers 4 are rotatably connected between the two track plates 1. Four limiting wheels 10 are fixedly connected to the two limiting rollers 4 respectively. The limiting wheels 10 arranged on two adjacent limiting rollers 4 are arranged alternately, and each limiting wheel 10 is arranged at equal intervals. The outer edge of the limiting wheel 10 is made of rubber material to increase the gripping force and ensure the correction effect. A positioning roller 11 is rotatably connected between the two track plates 1. The positioning roller 11 is located on one side of the four limiting rollers 4. A feeding mechanism for feeding a plate-type printed part into the center of the screen printing machine for printing is provided at one end of the track plate 1. A dust removal mechanism for removing dust from the surface of the plate-type printed part is provided between the two track plates 1.

[0024] Please combine Figure 1As shown, the feeding mechanism includes a driving roller 5 rotatably connected between two track plates 1. A printed protrusion structure is provided on the surface of the driving roller 5, which can increase the friction force when the driving roller 5 contacts the printed part, and the pushing effect is more obvious and anti-slip. A No. 2 servo motor 3 is fixedly connected to the outer side of one of the track plates 1, and the output end of the No. 2 servo motor 3 is connected to one end of the driving roller 5. An automatic pressing mechanism for pressing down the plate-type printed matter is provided above the driving roller 5.

[0025] Please combine Figure 1 As shown, the automatic pressing mechanism includes a limit platform 7 fixedly connected to one end of the two track plates 1, a slide groove is provided on the inner side of the limit platform 7, and sliders 8 are slidably connected to the inner sides of the two limit platforms 7. Elastic components 9 are provided between the upper sides of the two sliders 8 and the limit platform 7, and a pressing roller 6 is rotatably connected between the two sliders 8, and the pressing roller 6 cooperates with the driving roller 5.

[0026] Please combine Figure 1 As shown, the dust removal mechanism includes a chemical duster roller 12 rotatably connected between two track plates 1. The duster of the chemical duster roller 12 is made of a material with good softness to avoid damage to the printed part. A servo motor No. 2 is fixedly connected to the outer side of one of the track plates 1. The output end of the servo motor No. 2 passes through the track plate 1 and is connected to one end of the chemical duster roller 12. The lower side of the chemical duster roller 12 abuts against the upper surface of the plate-type printed part. A dust drainage mechanism is provided on one side of the chemical duster roller 12 for draining the dust raised by the chemical duster roller 12 from the surface of the plate-type printed part.

[0027] Please combine Figure 3 As shown, the dust drainage mechanism includes an inclined partition 16 fixedly connected between two track plates 1, and an ionization channel 13 is fixedly connected to the upper side of the inclined partition 16. The inlet of the ionization channel 13 and the chemical duster roller 12 are closely adjacent to and matched with each other. The lower edge of the inlet of the ionization channel 13 is slightly lower than the lowest point of the chemical duster roller 12, and the upper edge of the inlet of the ionization channel 13 is slightly higher than the highest point of the chemical duster roller 12, which can ensure that the dust raised by the chemical duster roller 12 is more fully captured by the ionization channel 13 to avoid polluting the working environment. An electrostatic dust removal mechanism for performing electrostatic dust removal operations on the airflow containing dust is arranged on the upper side of the ionization channel 13.

[0028] Please combine Figure 1 As shown, the electrostatic dust removal mechanism includes an electrostatic dust removal assembly 14 fixedly connected to the upper side of the ionization channel 13, and one end of the ionization channel 13 is connected to a centrifugal fan assembly 15.

[0029] Please combine Figure 2As shown, six rollers 17 are rotatably connected between the two track plates 1, and the six rollers 17 are located below the inclined partition 16. It should be particularly noted that the horizontal height of the rollers 17 is consistent with the limiting wheel 10 and the limiting roller 4, and when the plate printing piece is transferred from the limiting roller 4 to the roller 17, a smooth and seamless transition can be achieved.

[0030] The implementation principle of a dust removal device for a screen printing machine in the embodiment of the present application is as follows: the user feeds the plate-shaped printed piece to be printed between the driving roller 5 and the lower pressure roller 6. Since the driving roller 5 is provided with a printing structure that increases the friction force, when the elastic component 9 pushes the lower pressure roller 6 to press against the upper surface of the plate-shaped printed piece, the friction force generated by the driving roller 5 can push the plate-shaped printed piece to one side. Benefiting from the staggered arrangement of each set of limiting wheels 10, the plate-shaped printed piece can be transported in a straight line with high precision. It should be noted that the positioning roller 11 is located at the conveying The space formed between the positioning roller 11 and the roller 17 constitutes a channel for the plate-printed piece to move forward. The channel is adjacent to and located at the lower side of the chemical duster roller 12. Therefore, when the plate-printed piece passes under the chemical duster roller 12, the dust on the upper surface of the plate-printed piece can be cleaned by the high-speed rotating chemical duster roller 12. The raised dust enters the ionization channel 13 under the action of the airflow driven by the centrifugal fan assembly 15, and the dust in the air is adsorbed by the electrostatic dust removal assembly 14 to achieve the dust removal effect.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
