[0051] Embodiment 1

[0052] The present embodiment provides a plate passing device, as shown in Figure 1 and Figure 2 It comprises a temporary storage tank 1 and two sets of rotating opening and closing mechanisms 2. Among them, the top and the front and rear ends of the temporary storage tank 1 are open; the two sets of rotating opening and closing mechanisms 2 are arranged along the length direction of the temporary storage tank 1, and the two sets of rotating opening and closing mechanisms 2 and the tank wall of the temporary storage tank 1 form a liquid storage cavity; any rotating opening and closing mechanism 2 comprises two sets of oppositely arranged roller transmission mechanisms 21, any roller transmission mechanism 21 comprises a driving mechanism, a first rotating shaft 212 and a roller assembly; wherein the driving mechanism is arranged on the temporary storage tank 1, the roller assembly is arranged in the temporary storage tank 1, the driving end of the driving mechanism is connected with the first rotating shaft 212, the first rotating shaft 212 is connected with the roller assembly, and the driving mechanism drives the two sets of opposite roller assemblies to rotate towards each other and contact and extrude to form a sealing surface, or makes the two sets of opposite roller assemblies rotate away from each other to form a plate passing gap.

[0053] The end first reached when the workpiece is moved is defined as the front end, and the end reached last is defined as the rear end.

[0054] When the plate passing device is used, it is installed at the front end of the work tank body 3 of the workpiece processing system. The workpiece is moved to the rotating opening and closing mechanism 2 at the front end of the temporary storage tank 1 by the transmission belt. The driving mechanism of the two sets of opposite roller transmission mechanisms 21 simultaneously drives the first rotating shaft 212 on both sides of the temporary storage tank 1 to rotate. The first rotating shaft 212 drives the roller assemblies on both sides to rotate away from each other to form a first plate passing gap between the two sets of roller assemblies. The workpiece is driven by the transmission belt to pass through the first plate passing gap and enter the liquid storage cavity. The driving mechanism at the front end drives the first rotating shaft 212 to rotate in the opposite direction to drive the roller assemblies on both sides to rotate towards each other and form a sealing surface. The workpiece is moved to the rotating opening and closing mechanism 2 at the rear end of the temporary storage tank 1. The driving mechanism at the rear end drives the roller assemblies on both sides of the temporary storage tank 1 to rotate away from each other to form a second plate passing gap. The workpiece passes through the second plate passing gap and enters the work tank body 3. The driving mechanism at the rear end drives the roller assemblies on both sides of the temporary storage tank 1 to rotate towards each other and form a sealing surface. In this process, a small amount of liquid flowing out of the work tank body 3 through the second plate passing gap is stored in the temporary storage tank 1 through the sealing action of the two sets of roller assemblies to prevent the working liquid in the work tank body 3 from flowing out of the temporary storage tank 1.

[0055] When the workpiece passes through the plate, it does not contact the roller assemblies, effectively ensuring the surface quality of the workpiece. At the same time, the workpiece does not contact the plate passing, and the resistance during plate passing is small, which can quickly pass through the plate and improve the production efficiency. In addition, the workpiece moves horizontally into the work tank body 3, which does not need to set up a lifting mechanism compared with the lifting mechanism lifting across the tank, and does not occupy the height space of the factory building, so the required height space of the factory building is small.

[0056] Referring to Figures 3 to 5 The driving mechanism includes a driving source 2111 and a transmission mechanism. The driving source 2111 is arranged on the temporary storage tank 1. One end of the transmission mechanism is connected to the driving end of the driving source, and the other end is connected to the first rotating shaft 212. The driving source 2111 drives the first rotating shaft 212 to rotate through the transmission mechanism.

[0057] Optionally, the driving source 2111 is a linear actuator. The transmission mechanism includes a rack 21121 and a first gear 21122. The rack 21121 is connected to the driving end of the linear actuator. The first gear 21122 is arranged on the first rotating shaft 212 and is engaged with the first rack 21121. The first rotating shaft 212 is driven to rotate through the gear and rack 21121, and then drives the roller assembly to rotate around the first rotating shaft 212. For example, the linear actuator is a pneumatic cylinder, which is fixed on the top surface of the temporary storage tank 1. A connecting plate is arranged at the front end of the cylinder driving shaft. The rack 21121 is embedded in the connecting plate.

[0058] Any one of the roller transmission mechanism 21 further comprises an upper connecting arm 214 and a lower connecting arm 215 which are spaced apart on the first rotating shaft 212; the roller assembly comprises a second rotating shaft 2131 and a roller 2132 which is arranged outside the second rotating shaft 2131, and the upper connecting arm 214 and the lower connecting arm 215 are connected to the upper and lower ends of the second rotating shaft 2131 respectively. When the first rotating shaft 212 rotates, the upper connecting arm 214 and the lower connecting arm 215 rotate to drive the second rotating shaft 2131 and the roller 2132 to stably rotate around the first rotating shaft 212. The two rollers 2132 on the opposite sides rotate towards each other to form a sealing surface, or rotate away from each other to form a gap between the plates.

[0059] Optimally, the second rotating shaft 2131 is rotatably arranged on the upper connecting arm 214 and the lower connecting arm 215. The roller is made of soft material, such as sponge. While the second rotating shaft 2131 revolves around the first rotating shaft 212, it can also rotate itself to drive the roller 2132 to rotate, thereby changing the circumferential pressing position of the two opposite rollers 2132, preventing the roller 2132 from being pressed for a long time at a fixed position and being damaged or deformed, and preventing the sealing of the roller 2132 from failing.

[0060] Referring to Figure 5 and Figure 6 , any one of the roller transmission mechanism 21 further comprises a one-way rotating mechanism, which comprises a second gear 2161, a rotating support assembly and a third gear 2163. The second gear 2161 is fixedly arranged on the second rotating shaft 2131; the rotating support assembly is arranged on the temporary storage tank 1 and is sleeved outside the first rotating shaft 212; the rotating support assembly can rotate in one direction relative to the first rotating shaft 212; and the third gear 2163 is fixedly arranged on the rotating support assembly and is in mesh with the second gear 2161. The cylinder drives the first rotating shaft 212 to rotate, and the upper connecting arm 214 and the lower connecting arm 215 drive the second rotating shaft 2131 and the second gear 2161 to revolve around the first rotating shaft 212, and the rotating support assembly can rotate to make the second gear 2161 drive the third gear 2163 to rotate, and the third gear 2163 drives the second gear 2161 to rotate to drive the second rotating shaft 2131 and the roller 2132 to rotate, so as to change the circumferential position of the roller 2132 when it is pressed. Without the need to additionally provide a self-rotation driving device for the second rotating shaft 2131, the roller 2132 can be driven to rotate, and the plate passing device has a simple structure and low manufacturing cost. When the first rotating shaft 212 and the roller 2132 revolve around the first rotating shaft 212 to reset, the rotating support assembly cannot rotate in the opposite direction to fix the third gear 2163, and the second gear 2161 does not rotate by itself but revolves around the first rotating shaft 212 to reset, so as to keep the roller 2132 at the required circumferential position.

[0061] The rotating support assembly comprises a first fixed plate 21621, a first bearing sleeve 21622 and a first one-way bearing 21623. The first fixed plate 21621 is arranged on the temporary storage groove 1 and extends towards the first rotating shaft 212. The first bearing sleeve 21622 is arranged on the first fixed plate 21621 and is sleeved on the outside of the first rotating shaft 212. The first one-way bearing 21623 is arranged on the outside of the first bearing sleeve 21622. The third gear 2163 is fixedly arranged on the outside of the first one-way bearing 21623. The arrangement of the first one-way bearing 21623 enables the third gear 2163 to rotate in only one direction, so that the roller 2132 can remain in the required circumferential position after rotation.

[0062] Optionally, one end of the first fixed plate 21621 is fixed on the temporary storage groove 1, and the other end is sleeved on the outside of the first rotating shaft 212. The first bearing sleeve 21622 is fixedly arranged on the bottom of the first fixed plate 21621 by bolts to axially position the first one-way bearing 21623. The first fixed plate 21621, the first bearing sleeve 21622 and the first rotating shaft 212 all have gaps in the circumferential direction, which do not hinder the rotation of the first rotating shaft 212. The second one-way bearing is arranged on the first rotating shaft 212 at the bottom of the third gear 2163. The second bearing sleeve is arranged on the outside of the second one-way bearing. The top surface of the second bearing sleeve supports the third gear 2163 to axially position the third gear 2163 and the second one-way bearing.

[0063] Referring to Figure 7 The front side of the rotating opening and closing mechanism 2 located at the front end of the temporary storage groove 1 is provided with a guide piece 22. The guide piece 22 extends along the height direction of the temporary storage groove 1. The guide piece 22 has a guide opening in communication with the liquid storage cavity. The guide opening is flared, i.e., the opening is larger at the front and smaller at the back, to guide the workpiece to pass through the plate gap between the rollers. The guide piece 22 comprises guide plates oppositely arranged on both sides of the bottom of the temporary storage groove 1. The guide plates are inclined towards the middle part of the temporary storage groove 1.

[0064] The bottom of the temporary storage groove 1 at the front end of any roller 2132 is provided with a water baffle 23. The shape of the side of the water baffle 23 facing the roller 2132 is adapted to the outer circumferential wall of the roller 2132. In the closed state of the roller 2132, the bottoms of the rollers 2132 on both sides abut against the water baffles 23 respectively. The roller 2132 is tightly sealed with the water baffles 23, and the sealing effect is good.

[0065] Preferably, the bottom plate of the temporary storage groove 1 between the two groups of rotating opening and closing mechanisms 2 is provided with a first liquid discharge opening. The liquid in the liquid storage cavity is discharged through the first liquid discharge opening.

[0066] Referring to Figure 4, the top of the roller 2132 is provided with a cylinder mounting plate, the bottom of the roller 2132 is provided with a second fixed plate, the cylinder mounting plate is fixed on the top surface of the temporary storage tank 1, the cylinder is fixed on the cylinder mounting plate, and the first rotating shaft 212 is rotatably arranged on the cylinder mounting plate and the second fixed plate at the upper and lower ends. The first fixed plate 21621 and the second fixed plate are provided with a support column 217 to support the first fixed plate 21621 and the structure above it.

[0067] Best, see Figure 5 , the front end of the rack 21121 is provided with a limiting plate 24. The limiting plate 24 is fixed on the cylinder mounting plate to limit the linear motion distance of the rack 21121, to limit the opening angle of the roller 2132, and to prevent the roller 2132 from opening too large to cause a large amount of liquid to flow out of the working tank.

[0068] As a first alternative embodiment of embodiment 1, the rotating support assembly described above can also include a first fixed plate 21621 and a support shaft sleeve rotatably arranged on the first fixed plate 21621, and the third gear 2163 is arranged on the support shaft sleeve. When the third gear 2163 does not need to rotate, the support shaft sleeve is locked on the first fixed plate 21621 by the rotation locking structure. The rotating support assembly can rotate when the roller 2132 is opened, and can also rotate when the roller 2132 is closed, as long as it is one-way rotation, which can make the roller 2132 rotate and maintain at the required circumferential position.

[0069] As a second alternative embodiment of embodiment 1, the driving source 2111 can also be a rotary driving mechanism, and the transmission mechanism can be a speed reducer. The speed reducer is connected to the driving end of the rotary driving mechanism, and the output shaft of the speed reducer is connected to the first rotating shaft 212. The driving end of the rotary driving mechanism can also be directly connected to the first rotating shaft 212 without a transmission mechanism.

The workpiece moves horizontally into the working tank body 3, which does not need to set up a lifting mechanism and does not occupy the height space of the factory building compared with the lifting mechanism lifting across the tank.

[0073] Optionally, the working tank body 3 is provided with a plate passing device at both ends, and the workpiece processing device includes a plurality of working tank bodies 3, and adjacent working tank bodies 3 are communicated through the temporary storage tank 1.
