In actual production, there are multiple printing platens 100 on the transmission line 1, and the operator loads and unloads materials at a certain station. When the loaded printing platen 100 moves and leaves the loading station, the operator The printing medium that has just been printed can be removed, and then reloaded on the printing platen 100 after being removed. Therefore, the entire production process is a closed-loop circulation system. Since the printing platen 100 can move in the upper and lower layers, the length of the jet printing machine is shortened and the occupied area is reduced. More importantly, each transmission body 2 and the printing processing device connected to it are independent entities, and enterprise users can freely dock the transmission body 2 according to their own needs.

Drive device 44 .

As shown in Figures 6 and 7, the drive device 44 includes a horizontal shaft 441 arranged on the lifting bracket 41, the horizontal shaft 441 is provided with a rotating sprocket 442, and the rotating sprocket 442 is provided with There is a chain 443 matched with it, one end of the chain 443 is connected with the lifting platform 42 , and the other end of the chain 443 is connected with the piston rod of the driving cylinder 444 arranged on the lifting bracket 41 . When a printing platen 100 carries the printing medium from the lower layer 22 of a transmission body 2 to the lifting platform 42, the piston rod of the driving cylinder 444 is retracted, thereby pulling the chain 443, and then pulling the lifting platform 42 through the chain 443 Ascending, when the lifting receiving platform 42 is aligned with the upper layer 21 of the machine body, the conveying belt 43 on the lifting receiving table 42 will transport the printing platen 100 to the upper layer 21 of the machine body. When the printing platen 100 is about to move from the upper layer 21 of the body to the lower layer 22 of the body, the piston rod of the driving cylinder 444 is slowly extended, and the lifting receiving table 42 is then slowly lowered due to gravity, and then the conveying belt 43 on the lifting receiving table 42 will move The platen 100 is transported onto the lower floor 22 of the machine body. The design of the entire lifting structure is simple and ingenious, and the operation is very reliable.

As shown in Figures 2 to 5, the positioning device 5 includes positioning cylinders 51 respectively located on the left and right sides of the upper layer 21 of the body and the left and right sides of the lower layer 22 of the body, and the piston rod of the positioning cylinder 51 is provided with a positioning cylinder. For the chuck 52 , the left and right sides of the printing platen 100 are provided with positioning slots 100 c that can engage with the positioning chuck 52 .

As shown in FIG. 3 , the front end of the positioning clip 52 is narrow and the rear end is wide, and the opening of the positioning slot 100c is wide and the bottom is narrow. When the platen 100 with the printing medium arrives at the location of a certain printing processing device, the piston rod of the positioning cylinder 51 is extended, and the positioning chuck 52 on it is snapped into the positioning slot 100c, thereby completing the positioning. Because the front end of the positioning clip 52 is narrow and the rear end is wide, the opening width of the positioning clip 100c is narrow at the bottom, so when the positioning clip 52 cooperates with the positioning clip 100c, the positioning clip 52 can be easily snapped into the positioning slot. It does not matter even if the printing platen 100 is slightly inclined.

As shown in Figures 2 to 6, the front and rear limiting slots 100a and rear limiting slots 100b are respectively provided on the front and rear sides of the platen 100, and the upper blocking device 61 includes The upper layer blocking cylinder 611 of the upper layer 21, the piston rod of the upper layer blocking cylinder 611 is connected with the upper blocking member 612 that can cooperate with the front limit card slot 100a to block the movement of the printing platen 100 on the upper layer 21 of the machine body; The lower blocking device 62 includes a lower blocking cylinder 621 vertically arranged on the lower layer 22 of the machine body. Lower stop 622 for movement. When multiple printing plates 100 are running on the upper layer 21 of the machine body, in order to avoid that the printing medium in the previous process has not been processed, and the rear printing platen 100 moves forward and hits the front printing platen 100, it can pass through the upper layer The blocking device 61 blocks and limits the rear printing platen 100 , and when the front printing platen 100 leaves, the rear printing platen 100 is released by the upper blocking device 61 . When blocking the printing platen 100, the piston rod of the upper blocking cylinder 611 is stretched out, and the upper stopper 612 on the piston rod cooperates with the front limit slot 100a to block the forward movement of the printing platen 100; when the printing platen 100 is in the body When the lower layer 22 is running, the piston rod of the lower blocking cylinder 621 is stretched out, and the lower blocking member 622 on the piston rod cooperates with the rear limiting slot 100b to block the forward movement of the printing platen 100 . The whole structure is simple and the design is ingenious, which well solves the problem of the limit of the printing platen 100 during operation.

As shown in FIGS. 4 to 6 , the upper blocking member 612 is a roller connected to the piston rod of the upper blocking cylinder 611 , and the lower blocking member 622 is a roller connected to the piston rod of the lower blocking cylinder 621 .

The supporting rollers 8 and the endless belt 3 cooperate with each other to complete the transportation of the printing platen 100. The supporting rollers 8 play a supporting role to prevent the gravity of the printing platen 100 from being concentrated on the endless belt 3. Therefore, during the movement of the printing platen 100 Among them, there is rolling friction between the printing platen 100 and the support roller 8 , and there is sliding friction between the printing platen 100 and the endless belt 3 . Therefore, the combination of rolling friction and sliding friction reduces the friction compared to the sliding friction generated by the entire gravity of the printing platen 100 concentrated on the endless belt 3, and therefore, the electric energy consumed for driving the endless belt 3 to rotate is saved. Reduced costs. In addition, due to the support of the supporting rollers 8, the service life of the endless belt 3 is also extended, avoiding frequent replacement of components.

As shown in FIG. 1 , the printing processing device includes a spraying device 71 capable of spraying the printing medium on the printing platen 100 , and a drying device 72 capable of drying the printing medium on the printing platen 100 , a squeegee device 73 capable of squeegeeing the printing medium on the printing platen 100 and an inkjet device 74 capable of jetting ink to the printing medium on the printing platen 100 .

Since the transmission body 2 is a separate entity, enterprise users can freely adjust the transmission assembly line 1 according to their own needs. For example, when printing on a certain printing medium, some stations on the transmission line 1 can be selected, and unnecessary stations can be removed by removing the transmission body 2, so that the length of the transmission line 1 becomes shorter , improve the operation efficiency of the printing platen 100 on the transmission line 1, improve the production efficiency and reduce the cost. When it is necessary to add a process to a certain printing medium, it is only necessary to insert the transmission body 2 with the printing processing device into the original transmission line 1 . Therefore, by adding or subtracting the transmission body 2 or changing the arrangement order of the transmission body 2, the required printing machine stations can be easily established, and the free combination of the actual required functions of the printing machine can be realized, the production efficiency can be improved, the space can be saved, and the cost can be reduced.
