Description
Technical Field
The utility model relates to an auxiliary device of UV printing equipment, in particular to a feeding tensioning device of the UV printing equipment.
Background
UV printing apparatus need material loading overspeed device tensioner to carry out tensioning treatment to the mantle at the course of the work, and current material loading overspeed device tensioner is four rubber roll step drive types. The four-rubber-roller stepping transmission type feeding tensioning device is simple in structure and easy to operate, but the tensioning force of the flexible films with various specifications cannot be well controlled in different flexible film printing processes. The control on the soft film is either too tight or too loose, which greatly influences the printing effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the feeding and tensioning device of the UV printing equipment can accurately control the tensioning force of the flexible films with different specifications in the printing process, and ensure that the best printing effect is kept.
In order to solve the technical problem, the feeding tensioning device of the UV printing equipment comprises parallel feeding supporting rollers, feeding air expansion rollers are arranged above the feeding supporting rollers, transition rollers are arranged obliquely above the feeding air expansion rollers, a printing platform is arranged on the same horizontal plane as the transition rollers, front driving rollers are arranged obliquely below the printing platform, driving lower compression rollers are arranged right below the front driving rollers, the front driving rollers and the driving lower compression rollers are attached in parallel, receiving air expansion rollers are arranged obliquely below the driving lower compression rollers, receiving supporting rollers are arranged in parallel below the receiving air expansion rollers, a balance weight plate is arranged below the feeding air expansion rollers, a feeding tensioning roller is arranged at one end of the balance weight plate, and a rotating shaft is arranged in the middle of the balance weight plate.
According to a further optimization scheme of the technical scheme, a counterweight groove is formed in the other end of the counterweight plate.
According to the further optimization scheme of the technical scheme, the first photoelectric sensor and the second photoelectric sensor are arranged between the discharging tensioning roller and the transition roller.
According to the further optimization scheme of the technical scheme, the lamp box is arranged between the driving lower pressing roller and the material receiving air expansion roller.
According to the further optimization scheme of the technical scheme, the number of the transition rollers is three, and the transition rollers are arranged in parallel with the horizontal plane.
The feeding tensioning device of the UV printing equipment can realize different tensioning forces for the soft films with different specifications, can keep the soft films in the optimal tensioning state all the time in the printing process, does not wrinkle or slip, and ensures the optimal printing effect.
Drawings
Fig. 1 is a schematic structural diagram of an overall feeding tensioning device of a UV printing device.
Detailed Description
Referring to fig. 1, the feeding tensioning device of the UV printing equipment comprises two parallel feeding supporting rollers 1, wherein a feeding air expansion roller 2 is arranged above the feeding supporting rollers 1, and the feeding air expansion roller 2 and the feeding supporting rollers 1 are arranged in parallel. Blowing air inflation roller 2 below is provided with counterweight 4, blowing tensioning roller 3 is installed to counterweight 4 one side tip, counterweight 4 middle part is provided with rotation axis 41. The weight plate 4 is rotatable by a rotation shaft 41. And a counterweight slot 42 is formed in the other side of the counterweight plate 4, and the counterweight slot 42 is used for placing a counterweight.
Three transition rollers 6 are arranged obliquely above the discharging air expansion roller 2, and a structure parallel to the horizontal plane is adopted between the transition rollers 6.
Be provided with print platform 7 with the horizontal plane at transition roller 6, the oblique below of 7 ejection of compact sides of print platform is provided with front driving roller 8, be provided with drive compression roller 9 down under front driving roller 8, laminating, parallel arrangement between front driving roller 8 and the drive compression roller 9 down, drive compression roller 9 oblique below is provided with receipts material inflatable roller 12 down, receipts material inflatable roller 12 below parallel arrangement has two receipts material backing rolls 11, receives parallel arrangement between material inflatable roller 12 and the receipts material backing roll 11. A lamp box 10 is arranged between the driving lower pressing roller 9 and the material receiving air expansion roller 12. The light box 10 can ensure that the effect of printing is observed in a dark environment. A first photosensor 51 and a second photosensor 52 are provided between the discharge tension roller 3 and the transition roller. The second photoelectric sensor 52 is arranged right above the first photoelectric sensor 51, and the soft film tension condition can be detected through the first photoelectric sensor 51 and the second photoelectric sensor 52.
The working principle of the scheme is that the soft film 13 to be printed is sequentially wound among the discharging air expansion roller 2, the discharging tensioning roller 3, the transition roller 6, the front driving roller 8, the driving lower pressing roller 9 and the receiving air expansion roller 12. The counterweight in the counterweight groove 42 is adjusted according to the soft films 13 with different specifications, the discharging tension roller 3 is adjusted to the optimal position by utilizing the lever principle, and the tension degree of the soft films 13 is detected in real time by the first photoelectric sensor 51 and the second photoelectric sensor 52, so that the optimal state is ensured all the time.
