For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or connected through an intermediate medium, and can be internally connected and communicated between two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] As Figures 1 to 3 shown, an automatic sheet feeding device includes a frame body 10, a chain lifting device, a lifting suction plate device 30, and a push-pull cylinder 11.

[0030] The frame body 10 is a cubic frame structure. A pressure roller sheet discharging device 40 is arranged on the frame body 10 for docking with the conveyor belt of a sheet washing machine. The pressure roller sheet discharging device 40 is specifically arranged on the side surface of the frame body 10.

[0031] The chain lifting device is arranged inside the frame body 10. An elevating conveyor frame 20 that moves up and down inside the frame body 10 is provided in the chain lifting device. The elevating conveyor frame 20 is used for placing partition plates stacked together.

[0032] The lifting suction plate device 30 is slidably connected inside the frame body 10 through a mounting bracket 31, and is located on one side of the feeding end of the pressure roller sheet discharging device 40 and above the elevating conveyor frame 20. A suction cup 322 assembly 32 is provided in the lifting suction plate device 30 for sucking up the partition plates stacked in the elevating conveyor frame 20. Among them, the sliding between the mounting bracket 31 and the frame body 10 is realized through the connection of a guide rail and a slider.

[0033] The push-pull cylinder 11 is arranged on the frame body 10, specifically on the frame body 10 above the pressure roller sheet discharging device 40. The end of the piston rod of the push-pull cylinder 11 is connected to the mounting bracket 31 for driving the mounting bracket 31 to slide on the frame body 10.

[0034] In specific implementation, stack multiple partition boards on the lifting and conveying rack 20. The lifting and conveying rack 20 rises to the height at which the sucker 322 of the assembly 32 can suck the partition board and then stops. After sucking the partition board stacked on the top layer by the sucker 322 assembly 32, the push-pull air rod operates, pulling the mounting bracket 31 to move towards the pressure roller plate discharging device 40, so that one end of the partition board adsorbed by the sucker enters the pressure roller plate discharging device 40. At this time, the sucker 322 assembly 32 stops sucking, and the pressure roller plate discharging device 40 feeds the partition board onto the conveyor belt of the plate washing machine. The plate feeding process does not require manual intervention and has a high degree of automation.

[0035] In this embodiment, the chain type lifting device includes a lifting and conveying rack 20, two groups of transmission sprocket sets, two transmission chains 27, a synchronous transmission shaft 28 and a driving motor 29.

[0036] Lifting mounting plates 201 are vertically arranged on both sides of the lifting and conveying rack 20. Two groups of transmission sprocket sets are symmetrically arranged on the lifting mounting plates 201 on both sides of the lifting and conveying rack 20 and on both sides of the frame body 10 respectively. Two transmission chains 27 are symmetrically wound around the two groups of transmission sprocket sets. The driving motor 29 is connected to the frame body 10 above the lifting and plate sucking device 30. The driving shaft end of the driving motor 29 is connected with a speed reducer 291. The synchronous transmission shaft 28 is in transmission connection with the speed reducer 291. The two ends of the synchronous transmission shaft 28 are respectively connected with the sprockets in the two groups of transmission sprocket sets arranged on the frame body 10. The driving motor 29 cooperates with the speed reducer 291 to synchronously drive the transmission chain 27 to drive the lifting and conveying rack 20 to rise or fall smoothly through the synchronous transmission shaft 28.

[0037] Specifically, a fixing plate 202 is arranged on one side of the lifting mounting plate 201 on the frame body 10. The transmission sprocket set includes a first sprocket 21, a second sprocket 22, a third sprocket 23, a fourth sprocket 24, a fifth sprocket 25 and a sixth sprocket 26. The first sprocket 21 and the second sprocket 22 are symmetrically arranged above and below the fifth sprocket 25 and the sixth sprocket 26 on the outside of the lifting mounting plate 201. The third sprocket 23 is arranged inside the fixing plate 202 and is located obliquely below the second sprocket 22. The third sprocket 23 is arranged vertically opposite to the second sprocket 22 and is connected to the synchronous transmission shaft 28. The transmission chain 27 is sequentially wound around the first sprocket 21, the second sprocket 22, the third sprocket 23, the fourth sprocket 24, the fifth sprocket 25 and the sixth sprocket 26 in sequence, and the two ends that are vertically opposite are respectively fixed on the fixing plate 202 and the frame body 10.

[0038] Through the above-mentioned way of winding the transmission chain 27 around the sprockets, the tension of the transmission chain 27 wound around the sprockets can be always maintained, and the lifting and conveying rack 20 can also be stably lifted and lowered.

[0039] In addition, in order to make the lifting and conveying frame 20 more stable during the lifting process, sliders are provided on the lifting mounting plate 201, and guide rails connected to the sliders are provided in the vertical direction of the frame body 10 near the lifting mounting plate 201.

[0040] In this embodiment, a chain conveyor belt 203 is provided on the lifting and conveying frame 20, which is convenient for saving effort when placing the partition board. It only needs to place part of it on the chain conveyor belt and then it can all be moved in.

[0041] As Figures 1 to 4 shown, in this embodiment, the lifting suction plate device 30 includes a mounting bracket 31 and a suction cup 322 assembly 32. A cross bar 311 connected to the end of the piston rod of the push-pull cylinder 11 is provided on the mounting bracket 31, and the suction cup 322 assembly 32 is connected to both sides of the mounting bracket 31.

[0042] The suction cup 322 assembly 32 includes a mounting rod 321, a suction cup 322, and a suction cup cylinder 323. The end of the piston rod of the suction cup cylinder 323 is vertically perpendicular to the mounting rod 321 and connected. An L-shaped connecting piece 324 fixedly connected to the mounting bracket 31 is provided on the suction cup cylinder 323. The suction cup 322 is connected to the mounting rod 321 through a connecting rod 325 and is located below the mounting rod 321. A suction cup 322 buffer spring is sleeved on the connecting rod 325.

[0043] During specific implementation, the suction cup 322 connected to the mounting rod 321 is driven by the suction cup cylinder 323 to move up and down, so that the suction cup 322 adsorbs the partition board on the lifting and conveying frame 20.

[0044] Among them, at least two suction cups 322 are arranged at intervals in the length direction of the mounting rod 321, which is convenient for stably sucking and lifting the partition board.

[0045] As Figures 1 to 3 and Figure 5 shown, in this embodiment, the pressure roller plate discharging device 40 includes a roller frame 41, an upper pressure roller 42, and a lower pressure roller 43. The roller frames 41 are symmetrically arranged on the frame body 10. A pressing cylinder 45 connected to the bearing slider at the end of the upper pressure roller 42 is vertically provided on the roller frame 41. The two ends of the upper pressure roller 42 and the lower pressure roller 43 are connected to the roller frame 41 through bearing sliders, and a pressure roller driving motor 44 is connected to one end of the lower pressure roller 43.

[0046] During specific implementation, the upper pressure roller 42 is controlled by the pressing cylinder 45 to move up and down, which is convenient for the end of the partition board to enter. After the partition board enters, it is pressed tightly to prevent the partition board from slipping or running off during feeding.

[0047] An automatic sheet feeding device provided by the present utility model, compared with the prior art, stacks partition boards on the lifting and conveying rack 20 in the chain type lifting device. The lifting and conveying rack 20 rises in the frame body 10 to the height where the suction cup 322 component 32 can pick up. After the suction cup 322 component 32 adsorbs the partition board stacked on the top layer, the installation bracket 31 is pulled by the push-pull cylinder 11 to slide, so that one end of the partition board adsorbed by the suction cup 322 component 32 is sent into the pressure roller sheet discharging device 40 for automatic sheet feeding. The sheet feeding process does not require manual intervention, has a high degree of automation, and can adapt to large-scale sheet feeding, which can reduce the labor intensity of workers, lower the labor cost, and improve the production efficiency.

[0048] In the case of no conflict, the above embodiments and the features in the embodiments can be combined with each other.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
