Description

Technical Field

[0001] The utility model relates to the technical field of spraying and printing equipment, in particular to a carton spraying and printing device. Background Art

[0002] For the convenience of identification, barcodes and product models are required to be set on the surface of the product outer packaging box. The product model is generally fixed on the packaging box by manual pasting. Since the incoming materials for model marking are paper printed products, the cost is high, and a large amount of garbage is generated after pasting. Moreover, one person is required to complete the pasting action, resulting in a large labor cost. In addition, there are problems such as incoming material errors, manual pasting errors, and manual pasting inclinations in manual pasting. Therefore, the existing barcodes and product models on the surface of the packaging box are generally sprayed and printed by a spraying and printing device; a carton inkjet printer, as the name implies, is a mechanical device used to spray and print information on cartons in the carton packaging industry.

[0003] The current carton inkjet device mostly combines a conveyor and a packaging inkjet printer. When using the conveyor to transport the carton, the packaging inkjet printer sprays and prints information on the carton. In order to ensure that the packaging inkjet printer can effectively spray and print information on the carton, a limiting structure is often required for linear guidance during the transportation of the carton. This structure and usage method are inconvenient when calibrating cartons of different sizes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a carton spraying and printing device to overcome the above defects in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A carton spraying device according to the present utility model includes a workbench, on which there is a lifting table capable of moving up and down. The lifting table is located at the mid-position of the workbench in the left-right direction. The left and right ends of the workbench are hinged with transport plates. The front and rear ends of the lifting table are provided with sliding grooves, which are slidably matched with the transport plates. Electric rollers evenly distributed in the front and rear directions are rotatably connected in the transport plates. The hinged ends of the lifting table are higher than the hinged ends of the workbench. The transport plates are inclined. There are lifting mechanisms evenly distributed in the front and rear directions on the workbench. The lifting mechanism includes a cylinder fixed on the workbench. The upper end of the cylinder is connected with a telescopic air rod, and the upper end of the telescopic air rod is fixedly connected with the lower end of the lifting table. Two support plates distributed left and right are fixedly arranged on the upper end surfaces of the two transport plates. A control end is fixedly arranged on the upper end of the lifting table. Detection mechanisms are fixedly embedded on two support plates close to each other. Spraying mechanisms are fixedly arranged on two support plates far from each other. The spraying mechanisms are electrically connected to the control end and the detection mechanisms through transmission lines. The spraying mechanisms, the detection mechanisms and the detection mechanisms are all located at the mid-position of the workbench in the front-rear direction. Extension plates capable of sliding up and down are connected to two support plates far from each other. Ball bearings are rotatably connected to the mutually close ends of the support plates and the extension plates. A positioning rod is inserted into the support plates and the extension plates. The extension plates are provided with insertion openings evenly distributed up and down that can abut against the positioning rod. Two symmetric fixing blocks and fixing plates are fixedly arranged on the front part of the workbench and on the upper surface of the workbench. Hinged plates are hinged to the upper ends of the two fixing blocks. The hinged plates can abut against the adjacent fixing plates. Baffles are fixedly arranged on the front end surfaces of the two support plates. Elastic pieces are connected between the baffles and the hinged plates.

[0007] The beneficial effects of the present utility model are as follows:

[0008] By arranging a hinged plate, a baffle and an elastic piece at the front end of the support plate, when the carton is transferred to the transport plate, buffer work is carried out during the inclination of the carton, so as to maintain the stability of the carton during inclination. The elastic force of the elastic piece keeps the hinged plate in contact with the fixing plate, so that the hinged plate can repeatedly contact the carton for buffer work.

[0009] By means of the lifting mechanism supporting the lifting table, the height position of the lifting table is adjusted between the workbench and the lifting table with a vertical height difference, so as to change the inclination of the transport plate connected between the workbench and the lifting table. The transportation of cartons of different sizes is realized by the inclination of the transport plate, and there is no need to use an adjustment mechanism to adjust cartons of different sizes.

[0010] Through the up-and-down sliding of the extension plate within the support plate and the ball bearings connected to the support plate and the extension plate, the support plate and the extension plate can assist in transporting packaging boxes of different sizes, while maintaining the stability of the packaging boxes during transportation and reducing the friction force at the fitting part.

[0021] Embodiment 1:

[0022] Referring to Figures 1-6 , a carton spraying device according to an embodiment of the present invention includes a workbench 10. There is a lifting table 27 that can move up and down on the workbench 10. The lifting table 27 is located at the middle position in the left-right direction of the workbench 10. The left and right ends of the workbench 10 are hinged with a transport plate 14. Sliding grooves are provided at the front and rear ends of the lifting table 27, and the sliding grooves are in sliding fit with the transport plate 14. Electric rollers 20 evenly distributed in the front-rear direction are rotatably connected inside the transport plate 14. The hinged end of the lifting table 27 is higher than the hinged end of the workbench 10. The transport plate 14 is inclined. Lifting mechanisms 24 evenly distributed in the front-rear direction are provided on the workbench 10. The lifting mechanism 24 includes a cylinder 25 fixed on the workbench 10. The upper end of the cylinder 25 is connected with a telescopic air rod 26. The upper end of the telescopic air rod 26 is fixedly connected with the lower end of the lifting table 27. Two support plates 11 distributed left and right are fixedly provided on the upper end surfaces of the two transport plates 14. A control end 22 is fixedly provided at the upper end of the lifting table 27. Detection mechanisms 23 are fixedly embedded on two support plates 11 close to each other. Spraying mechanisms 21 are fixedly provided on two support plates 11 far from each other. The spraying mechanisms 21 are electrically connected to the control end 22 and the detection mechanisms 23 through transmission lines. The spraying mechanisms 21, the detection mechanisms 23 and the detection mechanisms 23 are all located at the middle position in the front-rear direction of the workbench 10. Extension plates 12 that can slide up and down are connected to both support plates 11 far from each other. Ball bearings 13 are rotatably connected to the mutually close ends of the support plates 11 and the extension plates 12. A positioning rod 28 is inserted into the support plates 11 and the extension plates 12. Insertion ports evenly distributed up and down are provided on the extension plate 12 and can abut against the positioning rod 28. Two fixing blocks 15 and fixing plates 16 that are symmetric left and right are fixedly provided at the front part of the workbench 10 and on the upper end surface of the workbench 10. Hinged plates 17 are hinged to the upper ends of the two fixing blocks 15. The hinged plates 17 can abut against the adjacent fixing plates 16. Baffles 18 are fixedly provided on the front end surfaces of the two support plates 11. Elastic sheets 19 are connected between the baffles 18 and the hinged plates 17.

[0023] The working process of this solution is as follows:

[0024] Put the packing box into the front end of the workbench 10. The packing box abuts against the transport plate 14 and moves from front to back under the rotation of the electric rollers 20 on the transport plate 14. When the packing box passes through the spraying mechanism 21, the spraying mechanism 21 sprays and prints one side of the packing box. Then, it moves backward through the transport of the electric rollers 20 and is transported out from the rear end of the transport plate 14.

[0025] When the packing box is transported from front to back to the transport plate 14 by the plane transport mechanism, the packing box moves to the upper part of the transport plate 14. The transport plate 14 is inclined under the action of the lifting mechanism 24. One end of the packing box abuts against the transport plate 14, and the end face on the other side abuts against the vertically arranged hinge plate 17. Under the action of gravity, the lower end face of the packing box gradually fits against the upper end face of the transport plate 14. The pressure received at the hinge plate 17 swings towards the end close to the baffle 18 after being buffered by the elastic sheet 19 to buffer the packing box. The packing box moves backward under the rotation of the electric rollers 20. The end of the packing box close to the support plate 11 and the extension plate 12 abuts against the ball 13. The rolling of the ball 13 reduces the friction between the packing box and the support plate 11 and the extension plate 12, so that the packing box runs smoothly on the transport plate 14. The control end 22 on the lifting mechanism 24 is powered on to supply power to the detection mechanism 23 through the connection of the transmission line, so that the detection mechanism 23 emits detection light. When the packing box is transported to the detection mechanism 23, after the detection mechanism 23 detects the presence of the packing box through the detection light, it is transmitted to the control end 22 in the form of an electrical signal through the transmission line. The control end 22 controls the spraying mechanism 21 to work. The control end 22 is connected to the external paint box through a connecting pipe, and the spraying mechanism 21 sprays and prints at the position of the packing box.

[0026] During operation, the lifting mechanism 24 is started to power on the cylinder 25. The cylinder 25 drives the telescopic air rod 26 connected to the upper end to stretch up and down, thereby adjusting the up and down height of the lifting platform 27, and further adjusting the inclination of the transport plate 14 through the lifting platform 27. The user pulls out the positioning rod 28 at the extension plate 12. After the positioning rod 28 is disengaged from the abutment at the extension plate 12, the extension plate 12 can slide up and down in the support plate 11, thereby adjusting the overall length of the support plate 11 and the extension plate 12. After the adjustment of the extension plate 12 is completed, the positioning rod 28 is reinserted so that the positioning rod 28 is clamped and matched with the insertion interfaces at different positions in the extension plate 12 to realize the adjustment of the extension plate 12.

[0027] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
