Description

Technical Field

[0001] The utility model relates to the technical field of canning tinplate technology, in particular to a printing positioning mechanism for a canning tinplate plate. Background Art

[0002] Printing is a technology that transfers ink from originals such as text, pictures, photos, anti-counterfeiting, etc. to the surface of paper, metal, fabric, plastic, leather and other materials through processes such as plate making, inking and pressurization, so as to batch copy the content of the original. Canning iron printing is mainly done on tinplate, so that exquisite patterns can be attached to the tinplate surface. In the canning process, the rolled iron sheet is cut into pieces, and then each piece of iron sheet is printed and dried. The iron sheet that can be made into multiple iron cans is cut into the corresponding size of a single can and then pressed into a can.

[0003] After searching, the announcement number CN207375433U is a printing device with an anti-biased printing function, including a conveying mechanism and a printing mechanism, the conveying mechanism is located at the input end of the printing mechanism, wherein the conveying mechanism is provided with at least two guide plates and a mounting seat, the mounting seat is provided with a driving rod and an auxiliary rod, the driving rod is provided with a driving wheel for conveying the printing material and a driving motor capable of rotating the driving rod, the auxiliary rod is provided with a signal output device for detecting the position of both sides of the printing material, the signal output device is connected with a detection rod, one end of the detection rod extends to the tail end of the conveying mechanism, the information output end of the signal output device is connected with a PLC controller, and the control end of the PLC controller is connected to the control end of the driving motor. The practical new beneficial effects are: 1. Its structure implements precision detection of the position of the printing material through the combination of the signal output device and the detection rod, which plays a role in avoiding the deviation of the printing material, thereby improving the printing accuracy. 2. Its structure controls the driving motor through a PLC controller. When the printing material is misaligned, the driving motor is stopped immediately to improve the quality of the finished product. Its defect is that when the equipment is positioning and guiding the plate, the positioning handle drives the adjustment side plate to cooperate with the operator to position and guide the printed plate to prevent deviation.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] The printing positioning mechanism for canning iron plate comprises a printing machine 1 and a conveyor belt 2, wherein the conveyor belt 2 is located inside the printing machine 1, and connecting seats 3 are arranged on the top of the printing machine 1 and at both ends of the conveyor belt 2, and two sets of connecting seats 3 are connected by a positioning assembly 4;

[0024] The positioning component 4 is used to automatically position the plate.

[0025] Furthermore, the positioning assembly 4 is composed of a limit plate 5, a rotating block 6, a rotating rod 7, a positive and negative screw rod 8, a connecting plate 9, a guide rod 10, a moving block 11, a connecting frame 12 and a suction cup 13. The two groups of limit plates 5 are respectively slidably connected to the inside of the two groups of connecting seats 3, the rotating block 6 is fixedly connected to the outside of the limit plate 5 and is located inside the connecting seat 3, the two groups of rotating rods 7 are both rotatably connected to the end of the rotating block 6 away from the limit plate 5, the positive and negative screw rod 8 is located at the end of the two groups of rotating rods 7 away from the rotating block 6, the connecting plate 9 is located at the bottom of the limit plate 5, the guide rod 10 is rotatably connected to the end of the connecting plate 9 away from the limit plate 5, the moving block 11 is located between the two groups of guide rods 10, the connecting frame 12 is located at the top of the moving block 11, and multiple groups of suction cups 13 are all located at the top of the connecting frame 12.

[0026] Among them, one end of the rotating rod 7 close to the forward and reverse screw rod 8 is rotatably connected with a driving block 14, and the driving block 14 and the forward and reverse screw rod 8 are threadedly connected. When the driving block 14 and the forward and reverse screw rod 8 are threadedly connected, when the forward and reverse screw rod 8 rotates, it can drive the driving block 14 to move, so that the rotating rod 7 can be moved, and the rotating block 6 can be moved, so that the limit plate 5 can be moved. The two sets of limit plates 5 can be used to position the plate to prevent the plate from being offset, which will affect the printing effect.

[0027] Secondly, moving grooves 15 are provided at both ends of the moving block 11 near the two groups of guide rods 10.

Through the linkage design, the two groups of guide rods 10 can be displaced synchronously, driving the moving block 11 to displace, preventing the two groups of guide rods 10 from being displaced asynchronously, driving and affecting the displacement of the moving block 11.

[0030] Furthermore, a guide groove is opened inside the connecting seat 3, and the internal structure size of the guide groove is designed to correspond to the external structure size of the limit plate 5 and the connecting plate 9. The connecting seat 3 is connected to the limit plate 5 and the connecting plate 9 through the guide groove, and the limit plate 5 and the connecting plate 9 are connected to the guide groove. When the limit plate 5 and the connecting plate 9 are displaced, they can be guided by the guide groove to prevent deviation, which affects the positioning of the plate.

[0031] In this embodiment, the implementation scenario is specifically as follows: in actual use, a plate is placed on the top of the conveyor belt 2, and the plate can be displaced to the inside of the printing machine 1 through the conveyor belt 2, and the driving motor is driven to drive the driving rod 20 to rotate, so that the first bevel gear 21 can be rotated, and the second bevel gear 22 is driven to rotate, so that the transmission rod 23 can be rotated, so that the two sets of driving rods 20 can be rotated, and the second driving wheel 19 is driven to rotate, so that the driving belt 18 can be displaced, and the first driving wheel 17 is driven to rotate, so that the forward and reverse screw rods 8 can be rotated, and when the forward and reverse screw rods 8 rotate, the driving block 14 can be displaced, so that the rotating rod 7 can be displaced, and the rotating block 6 can be displaced, so that the limit plate 5 can The plate can be displaced, and the plate can be positioned by two sets of limit plates 5 to prevent the plate from deflecting, which will affect the printing effect. When the limit plates 5 are displaced, the connecting plates 9 are driven to be displaced, so that the guide rods 10 can be displaced. The two sets of guide rods 10 are displaced inside the two sets of movable grooves 15. The inclined structure design of the movable grooves 15 enables the movable blocks 11 to be displaced, driving the connecting frames 12 to be displaced, thereby enabling multiple sets of suction cups 13 to be displaced and contact the plate. When the two sets of limit plates 5 limit the plate, the suction cups 13 contact the bottom of the plate and can adsorb it, thereby increasing the stability of the plate and preventing it from deflecting. Compared with the existing plate printing positioning, the utility model can improve the overall practicality of plate printing positioning through design.
