Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a printing device which is convenient for positioning a carton. Background Art

[0002] Printing is a technology that allows the mass reproduction of original text, images, photos, and anti-counterfeiting materials by transferring ink onto surfaces such as paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressurization. Specifically, printing involves transferring approved printing plates onto substrates using printing machinery and specialized inks.

[0003] Carton printing devices typically feature a positioning assembly to position the carton and ensure stability during the printing process. However, existing positioning devices often only perform this single function and lack a crucial auxiliary component (a cleaning assembly) to automatically clean the carton after positioning. This results in an untidy carton surface, which in turn affects print quality and reduces the functionality and practicality of the device. To enhance its structure, a printing device that facilitates carton positioning is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-7 A printing device that facilitates carton positioning includes a box body 1, in which a printing component is provided. The specific structure and working principle of the printing component can be referred to the prior art and will not be repeated in this solution.

[0029] A support rod 3 is provided on the box body 1 through the opening, and a movable frame 2 is slidably mounted on the support rod 3. There is a certain friction between the movable frame 2 and the support rod 3 to ensure that the movable frame 2 will not slide on the support rod 3 without strong external force intervention.

[0030] The movable frame 2 is provided with two rotating grooves 11, a transmission chamber 15 is provided inside the movable frame 2, a first motor 16 is provided in the transmission chamber 15, a screw 12 extending into the transmission chamber 15 is rotatably provided in the two rotating grooves 11, the screw 12 is connected to the first motor 16 through a transmission mechanism, and a moving block 13 is provided on the two screws 12 through a first limiting mechanism threaded sleeve, a positioning plate 4 is installed on the moving block 13, and a moving groove 19 is provided on the two positioning plates 4. A reciprocating screw 20 is provided in the moving groove 19 through the second motor, and a connecting rod 8 is provided on the reciprocating screw 20 through a second limiting mechanism threaded sleeve, and a movable block 5 and a movable sleeve 6 are respectively provided on the two connecting rods 8, and a brush 7 is provided on the movable block 5 and the movable sleeve 6.

[0031] The transmission mechanism includes a driving gear 17 mounted on the output shaft of the first motor 16, and a transmission gear 18 mounted on the screw 12, and the driving gear 17 meshes with the transmission gear 18. Both the driving gear 17 and the transmission gear 18 are bevel gears, and the meshing mode is vertical meshing.

[0032] The first limiting mechanism includes a first limiting rod 14 mounted within the rotation slot 11. The first limiting rod 14 is parallel to the screw 12 and slides through the movable block 13. The second limiting mechanism includes a second limiting rod 21 mounted within the movement slot 19. The second limiting rod 21 is parallel to the reciprocating screw 20 and slides through the connecting rod 8. Both the first limiting rod 14 and the second limiting rod 21 function as limiting rods, respectively, for the movable block 13 and the connecting rod 8, preventing them from rotating with the screw 12 and the reciprocating screw 20.

[0033] The movable block 5 is a rectangular column, and the movable sleeve 6 is U-shaped. The two can be moved away from each other to form a longer cleaning component, or moved closer to each other to form a shorter cleaning component.

[0034] The hairbrush 7 on the movable block 5 is provided with one, and the hairbrush 7 on the movable cover 6 is provided with two. Only have such design, just can when movable block 5 and movable cover 6 move and form longer cleaning assembly, still have hairbrush 7 to carry out cleaning operation.

[0035] A plurality of buffer blocks 10 are provided on the vertical outer wall of the movable frame 2 near the box body 1. The buffer blocks 10 are made of rubber. The buffer blocks 10 prevent the movable frame 2 from moving and hitting the inner wall of the box body 1. They play a buffering role.

[0036] A fixing plate is provided on the plurality of support rods 3. The setting of the fixing plate prevents the movable frame 2 from being separated from the support rods 3. A handle 9 is provided on the vertical outer wall of the movable frame 2 away from the box body 1. The handle 9 is convenient for grasping, so that the movable frame 2 can be pushed and pulled.

[0037] When the utility model is used, the carton to be printed is placed above the movable frame 2. In the initial state, the movable block 5 and the movable sleeve 6 are away from the box body 1 and staggered with the above-mentioned carton. Then the second motor is started to drive the reciprocating screw 20 to rotate. At this time, the connecting rod 8 drives the movable block 5 and the movable sleeve 6 to move, and the wiping operation can be performed by moving back and forth on the surface of the carton.

[0038] When the first motor 16 is started, the first motor 16 can drive the screw 12 to rotate with the help of the driving gear 17 and the transmission gear 18. When the screw 12 rotates, the moving block 13 can drive the positioning plate 4 to move. The two positioning plates 4 move close to each other to achieve the positioning and clamping of the carton, ensuring its stability during cleaning and when entering the box body 1 for printing after cleaning.

[0039] The distance between the two positioning plates 4 is adjustable, so it can adapt to the positioning and clamping of cartons of different sizes within a certain range. When the distance between the positioning plates 4 is adjusted, the length of the cleaning assembly composed of the movable block 5 and the movable sleeve 6 will also change synchronously, ensuring the practicality of the device.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
