Description

Technical Field

[0001] The present application relates to the field of printing equipment, and in particular to an automatic plate adjustment structure of packaging box printing equipment. Background Art

[0002] Screen printing refers to using a silk screen as a base plate and making a screen printing plate with images through a photosensitive plate-making method; printing is performed based on the basic principle that the mesh holes of the image part of the screen printing plate can pass through the ink, while the mesh holes of the non-image part cannot pass through the ink; when printing, pour ink into one end of the screen printing plate, apply a certain pressure to the ink part on the screen printing plate with a scraper, and move at a constant speed toward the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh holes of the image part by the scraper onto the substrate. This method is usually used for printing packaging boxes;

[0003] Referring to the Chinese patent application with publication number CN116749636B, a printing machine for printing patterns on packaging paper boxes is disclosed. Through the action of a clamping component and a lifting component, an air bag squeezes the packaging paperboard and presses it against a screen printing device. Since the air bag is a flexible squeeze, it avoids the irreversible thinning of the packaging paperboard caused by the squeeze deformation of the packaging paperboard by hard squeeze, which reduces the heat preservation, heat insulation and shock absorption performance of the corrugated paperboard when in use.

[0004] In the prior art, when a batch of packaging box cardboards passes under the printing plate in sequence, a fixing mechanism is set on the conveying mechanism to ensure the printing effect of the printing equipment on the packaging box cardboard. However, the packaging box cardboard usually needs to be printed at different positions. The conventional adjustment method is that the staff removes the packaging box cardboard from the fixing mechanism, adjusts the corresponding position and reprints. However, when printing a batch of packaging box cardboards, the operation is cumbersome, which affects the printing efficiency of the packaging box cardboard. For this reason, we designed an automatic plate adjustment structure for packaging box printing equipment. Utility Model Content

[0037] Screen printing refers to the use of a silk screen as a base, and through the photosensitive platemaking method, a screen printing plate with images is made; printing is performed based on the basic principle that the mesh holes of the image and text part of the screen printing plate can pass ink, while the mesh holes of the non-image and text part cannot pass ink. When printing on packaging box cardboard, it is usually necessary to manually adjust the printing plate.

[0038] In the related art, a printing machine for printing patterns on packaging paper boxes uses an air bag to squeeze the packaging box cardboard and press it against the screen printing device through the action of a clamping component and a lifting component. Since the air bag is a flexible squeeze, it avoids the irreversible thinning of the packaging box cardboard caused by hard squeezing, which reduces the thermal insulation, heat insulation and shock absorption performance of the corrugated cardboard during use.

[0039] Based on this, in order to improve the problem in the related art that when adjusting the printing plate, the staff needs to remove the packaging box cardboard on the fixing mechanism, adjust the corresponding position and re-fix it, but when printing a batch of packaging box cardboards, the operation is cumbersome, which affects the printing efficiency of the packaging box cardboard. The embodiment of the present application provides the following solution.

[0040] See also Figures 1 to 5An automatic plate adjustment structure of a packaging box printing device includes a machine platform 1, a printing mechanism 9, a printing plate 10, a positioning lamp, a high-precision camera and a control panel 15. The machine platform 1 is provided with a mobile mounting platform, and the mobile mounting platform is provided with a fixed platform 8. The printing mechanism 9 and the printing plate 10 are fixedly installed on the fixed platform 8, and the printing plate 10 is arranged below the printing mechanism 9. The machine platform 1 is provided with a displacement adjustment mechanism for adjusting the printing plate 10 on the mobile mounting platform in a horizontal linear direction.

[0041] The displacement adjustment mechanism includes a screw rod 3 and a first motor 4. A slide groove 2 is provided on the machine platform 1, and the screw rod 3 is arranged in the slide groove 2. The first motor 4 is fixedly mounted on the side wall of the machine platform 1. The output end of the first motor 4 is coaxially fixedly connected with the screw rod 3. A threaded hole matching the thread of the screw rod 3 is provided on the nut slider 14.

[0042] The effect of such arrangement is that, through the cooperation of the positioning light and the high-precision camera, the positioning light projects a positioning frame onto the position where the packaging box cardboard needs to be printed. Since a threaded hole compatible with the screw 3 is provided on the nut slider 14 at the bottom of the mobile mounting platform, the information feedback from the high-precision camera is received through the control board 15 to control the output end of the first motor 4 to work. When the output end of the first motor 4 drives the screw 3 to rotate, the nut slider 14 drives the mobile mounting platform to move horizontally on the machine 1, so that the printing plate 10 and the printing mechanism 9 on the mobile mounting platform are adjusted along the horizontal straight line direction to the position where the packaging box cardboard needs to be printed.

[0043] See also Figure 4 and Figure 5 The mobile mounting table is provided with an angle adjustment mechanism, which is used to adjust the horizontal angle of the printing plate 10, so as to facilitate adjusting the angle of the printing plate 10 to the required printing position of the packaging box paperboard to keep it parallel;

[0044] The angle adjustment mechanism includes a second motor 11, a worm 12 and a worm wheel 13. The second motor 11 is fixedly mounted on the outer wall of the fixed base 5. The worm 12 is arranged in the mounting cavity of the fixed base 5. The output end of the second motor 11 is coaxially fixedly connected with the worm 12. The worm wheel 13 is fixedly connected with the mounting body 6. The worm 12 and the worm wheel 13 are meshed for transmission.

[0045] The effect of such arrangement is that when it is necessary to print on the packaging box cardboard in an inclined direction, a positioning frame is projected by the positioning light, information feedback from the high-precision camera is received by the control board 15, and the output end of the second motor 11 is controlled by the control board 15 to drive the worm 12 and the worm wheel 13 to engage and transmit, so that the mounting body 6 rotates relative to the fixed base 5, so as to facilitate adjusting the angle of the printing plate 10 to keep it parallel to the required printing position of the packaging box cardboard.

[0046] See also Figure 4 and Figure 5The mobile mounting platform includes a fixed base 5 and a mounting body 6. A nut slider 14 is provided at the bottom of the fixed base 5. The mounting body 6 is arranged on the fixed base 5. A group of mounting blocks 7 are provided on the mounting body 6. The fixed platform 8 is fixedly connected to the mounting body 6 through the mounting blocks 7. A mounting cavity is provided in the fixed base 5.

[0047] The effect of such a setting is to facilitate the adjustment of the printing plate 10 on the mobile mounting table according to the required printing position of the packaging box cardboard. The operation is simple and convenient. Compared with the existing technology for assembly line batch manual adjustment, the printing efficiency of the packaging box cardboard is greatly improved.

[0048] See also Figure 1 A mounting frame is provided on the fixed platform 8, a positioning light is provided on the mounting frame, a steering servo is provided on the mounting frame, a control panel 15 is provided on the machine platform 1, and the control panel 15 is respectively connected with the high-precision camera, the positioning light, the first motor 4 and the second motor 11 by electrical signals;

[0049] With such an arrangement, the angle tracking of the positioning light is achieved through the steering servo, so that the positioning frame projected by the positioning light can be accurately projected to the position where the packaging box cardboard needs to be printed. At the same time, the control board 15 calculates the path of the printing plate 10 under the displacement adjustment mechanism and the angle adjustment mechanism to adjust the printing plate 10 to the position where the packaging box cardboard needs to be printed.

[0050] See also Figures 1 to 3 , a plurality of feet 16 and a plurality of universal wheels 17 are respectively provided at the bottom of the machine 1;

[0051] Such an arrangement facilitates maintaining the stability of the printing mechanism 9 in printing the packaging box cardboard, and at the same time facilitates the movement of the equipment by switching the universal wheels 17 and the feet 16.

[0052] From the above, we can see that the working principle of this application is as follows:

[0053] Through the cooperation of the positioning light and the high-precision camera, the positioning light projects the positioning frame on the position where the packaging box cardboard needs to be printed. Since the nut slider 14 at the bottom of the mobile mounting platform is provided with a threaded hole adapted to the screw 3, the control board 15 receives information feedback from the high-precision camera to control the output end of the first motor 4 to work. When the output end of the first motor 4 drives the screw 3 to rotate, the nut slider 14 drives the mobile mounting platform to move horizontally on the machine 1.

[0054] The output end of the second motor 11 is controlled by the control board 15 to drive the worm 12 and the worm wheel 13 to engage and transmit, so that the installation body 6 rotates relative to the fixed base 5, so as to adjust the angle of the printing plate 10 to the required printing position of the packaging box cardboard to keep it parallel. At the same time, the control board 15 calculates the path of the printing plate 10 under the displacement adjustment mechanism and the angle adjustment mechanism, so as to adjust the printing plate 10 to the required printing position of the packaging box cardboard.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
