The following further description is made with reference to the embodiments shown in the drawings.

Examples

As shown in figure 1, the plant fiber molding machine comprises a suction filtration molding device 1, a wet blank transfer device 2 and a frame (an upper frame 3, a lower frame 4 and a pull rod 5). The suction filtration forming device 1 comprises a suction filtration forming die 1.1 and a slurry tank 1.2, wherein the suction filtration forming die 1.1 sucks slurry in the slurry tank 1.2 in vacuum to prepare the slurry into a wet blank; the frame consists of a pull rod 5, a lower frame 4 and an upper frame 3, wherein the upper frame 3 is fixed on the lower frame 4 by the pull rod 5, so that the upper frame 3 and the lower frame 4 keep a certain distance; the suction filter forming device 1 is arranged in the lower frame 4, the wet blank transfer device 2 is positioned above the suction filter forming device 1, and the wet blank transfer die 2.1 of the wet blank transfer device 2 can vertically move up and down so as to move out the wet blank in the suction filter forming die 1.1 from the suction filter forming die 1.1. After the wet blank is manufactured in the suction filter forming die 1.1, the wet blank transfer die 2.1 vertically moves downwards to be accurately matched with the suction filter forming die 1.1, during die matching, the wet blank transfer die 2.1 is communicated with vacuum to generate negative pressure, the wet blank in the suction filter forming die 1.1 is sucked up, then the wet blank transfer die 2.1 drives the wet blank to vertically move upwards, the wet blank is moved out from the suction filter forming die 1.1 and is sent to the next procedure for drying or other treatment. Because the wet blank is not solidified and shaped, in the process of transferring the wet blank, if the mold closing precision of the wet blank transfer mold 2.1 and the suction filter forming mold 1.1 is not high or the wet blank transfer mold 2.1 is unstable in moving up and down, the wet blank is easy to damage and generate cracks. Therefore, the wet blank transfer die 2.1 moves up and down to accurately close the die 1.1 of the suction filter forming die 1 by moving the wet blank transfer die 2.1 vertically downwards; 2, the wet blank transfer die 2.1 vertically moves up and down stably, the displacement is accurate, and the speed switching is stable; 3, the sliding column 2.3 is fixed at the central position of the wet blank transfer mould 2.1, so as to avoid the phenomenon that the wet blank transfer mould is not parallel to the suction filter mould due to the unbalance of the wet blank transfer mould caused by the gravity center of the wet blank transfer mould deviating from the central line of the sliding column 2.3, and 4, the wet blank transfer mould 2.1 can stably and accurately stay at a certain specified position in the vertical direction. The performance of the green compact transfer apparatus 2 is in accordance with the above requirements.

As shown in fig. 1, 2 and 2.1, a slide column 2.3 is positioned on the upper frame 3 and right above the suction filter forming device 1, the slide column 2.3 can vertically slide up and down relative to the upper frame 3, a wet blank transfer mold 2.1 is fixed on a wet blank transfer mold mounting plate 2.2, a wet blank transfer mold mounting plate 2.2 for fixing the wet blank transfer mold 2.1 is fixed at one end of the slide column 2.3, and the wet blank transfer mold 2.1 can also be directly fixed at one end of the slide column 2.3 without the wet blank transfer mold mounting plate 2.2, but the gravity center of the wet blank transfer mold is coincident with the center line of the slide column 2.3.

As shown in fig. 1, 3 and 3.1, a transfer mold linear guide 2.4 capable of sliding up and down on a transfer slide block 2.5 is arranged on a slide column 2.3, and the transfer slide block 2.5 is fixed on an upper frame 3. The transfer die linear guide 2.4 is a linear guide, and the transfer slide block 2.5 and the transfer die linear guide 2.4 perform relative linear sliding. The sliding column 2.3 can move linearly up and down on a transfer slide block 2.5 fixed on the upper frame by a transfer mould linear guide rail 2.4. The sliding column 2.3 with good guidance quality ensures the movement precision of the wet blank transfer mould 2.1 when moving up and down, and the wet blank transfer mould 2.1 can stably vertically move up and down in a straight line under the guidance and the drive of the sliding column 2.3; the up-and-down linear sliding between the transfer mould linear guide rail 2.4 and the transfer slide block 2.5 reduces the friction resistance of the up-and-down motion of the wet blank transfer mould 2.1, and provides possibility for rapid and stable up-and-down motion.

As shown in fig. 3.3, the linear movement between the transfer slide 2.5 and the transfer mould linear guide 2.4 is relative. Conversely, the transfer die linear guide 2.4 is fixed on the upper frame 3, and the transfer slide block 2.5 is arranged on the slide column 2.3, so that the slide column 2.3 can move linearly up and down along the transfer die linear guide 2.4 through the transfer slide block 2.5.

In order to increase the guiding effect and stability of the sliding column 2.3, as shown in fig. 3, 3.1 and 3.3, the transfer sliders 2.5 are divided into two or more groups, the two or more groups of adjacent transfer sliders 2.5 are separated by a certain distance, and the transfer mold linear guide rails 2.4 fixed on the sliding column 2.3 slide up and down on the two or more groups of upper and lower transfer sliders 2.5 fixed on the frame; or, two or more groups of upper and lower transfer sliders 2.5 fixed on the sliding column 2.3 at a certain distance slide up and down on a transfer mold linear guide rail 2.4 fixed on the frame; therefore, the guidance of the sliding column 2.3 is greatly improved, and the stability of the up-and-down movement and the accuracy of up-and-down positioning of the wet blank transfer die 2.1 are realized.

The wet blank transfer mold 2.1 (or the wet blank transfer mold mounting plate 2.2 is added) has certain weight, the wet blank transfer mold 2.1 is driven to vertically move up and down by the sliding column 2.3 which is fixed with the transfer mold linear guide rail 2.4, the sliding column 2.3 is fixed at the central position of the wet blank transfer mold 2.1, the gravity center of the wet blank transfer mold does not deviate from the central line of the sliding column 2.3, the phenomenon that the wet blank transfer mold is not parallel to the suction filter mold due to the fact that the wet blank transfer mold loses balance because the gravity center deviates from the central line of the sliding column 2.3 is avoided, and therefore the parallelism of the wet blank transfer mold and the suction filter mold is fully ensured structurally. Therefore, the slide column 2.3 should be arranged directly above the suction mould.

The wet blank transfer die 2.1 (or the wet blank transfer die mounting plate 2.2 added) and the slide 2.3 have a certain weight, and the weight force generated by the weight is applied to the slide 2.3 and the wet blank transfer die 2.1 and becomes a resistance to the vertical upward movement of the wet blank transfer die 2.1. In order to overcome the gravity, a balance cylinder is specially arranged to balance the gravity of the wet blank transfer die, the wet blank transfer die mounting plate and the sliding column, as shown in fig. 1.1, a balance cylinder 2.13 is fixed on the upper frame 3, a piston rod of the balance cylinder 2.13 is connected with the sliding column 2.3, the axes of the piston rod and the sliding column are parallel, and the pulling force of the balance cylinder 2.13 is matched with the weight of the wet blank transfer die, the wet blank transfer die mounting plate and the sliding column. So as to realize the tension of the balance cylinder 2.13 to balance the gravity of the wet blank transfer die 2.1, the sliding column 2.3 and the wet blank transfer die mounting plate 2.2.

A transfer die weight counterbalance 2.6 may also be employed to balance the weight of the wet blank transfer die, wet blank transfer die mounting plate and slide post. As shown in fig. 1, 2 and 3, a set of fixed pulley (or sprocket) 2.10 is disposed above the strut 2.3, the fixed pulley (or sprocket) 2.10 is rotatably positioned on the upper frame, the strut 2.3 is positioned at one side of the fixed pulley (or sprocket) 2.10, a weight-transferring mold weight balance 2.6 is positioned at the other side of the fixed pulley (or sprocket) 2.10, as shown in fig. 3, a weight balance connecting line (or chain) 2.9 crosses the fixed pulley (or sprocket) 2.10 to connect the weight-transferring mold weight balance 2.6 and the strut 2.3 together, and the weight balance connecting line 2.9 is a flexible cable which can be a rope, a wire rope, a chain, etc. In this way, the weight balance connecting line (or chain) 2.9 respectively hangs the weight balance weight 2.6 of the transfer die and the sliding column 2.3 on two sides of the fixed pulley (or chain wheel) 2.10, the weight balance weight 2.6 of the transfer die pulls the sliding column 2.3 through the weight balance connecting line (or chain) 2.9 crossing the fixed pulley (or chain wheel) 2.10, so as to realize that the gravity of the weight balance weight 2.6 of the transfer die balances the gravity of the wet blank transfer die 2.1, the sliding column 2.3 and the mounting plate 2.2 of the wet blank transfer die, thus the weight balance weight of the wet blank transfer die 2.3 and the wet blank transfer die 2.1 can freely move up and down, the stability of the up and down movement of the sliding column 2.3 and the wet blank transfer die 2.1 is effectively increased, the weight balance weight of the wet blank transfer die 2.1 and the sliding column 2.3 can effectively balance the weight of the wet blank transfer die 2.1, the risk of the wet blank transfer die not only is eliminated, but also the load of the wet blank transfer die 2.1 when the wet blank transfer die. The weight balance connecting line (or chain) 2.9 and the fixed pulley (or chain wheel) 2.10 can adopt a chain and a chain wheel respectively, and can also be a rope or a steel cable with certain strength and a matched fixed pulley. The weight balance block 2.6 of the transfer mould, the balance linear guide rail 2.7, the balance slide block 2.8, the weight balance connecting line (or chain) 2.9 and the fixed pulley (or chain wheel) 2.10 can be a group or a plurality of groups.

When the wet blank transfer die 2.1 descends, the weight balance block 2.6 of the transfer die ascends under the pulling of the weight balance connecting line (or chain) 2.9; when the wet blank transfer mould 2.1 goes upwards, the weight balance block 2.6 of the transfer mould goes downwards by the self gravity.

As shown in fig. 1, 3, 3.1, 3.2, the up-and-down movement of the spool 2.3, which has achieved up-and-down sliding and is almost in a gravity equilibrium state, is achieved by a servo motor drive 2.11, said servo motor drive 2.11 comprising a rack 2.11-1, a gear 2.11-2, a servo motor 2.12. A rack 2.11-1 is fixed on the sliding column 2.3, a gear 2.11-2 is meshed with the rack 2.11-1, and the gear 2.11-2 is driven by a servo motor. The rotation of the servo motor drives the gear 2.11-2 to rotate so as to drive the rack 2.11-1 and the sliding column 2.3 to move up and down together; or the servo motor can realize the up-and-down movement of the sliding column 2.3 and the wet blank transfer die 2.1 through the transmission of a screw-nut pair; the servo motor can also realize the up-and-down movement of the slide column 2.3 and the wet blank transfer die 2.1 through the transmission of a synchronous belt.

Driven by a servo motor 2.12 and under the guiding action of a transfer die linear guide rail 2.4, the wet blank transfer die 2.1 can stably and accurately perform vertical up-and-down linear motion or stably and accurately stay at a certain specified position in the vertical direction.

As shown in fig. 3, in order to prevent the transfer mold weight balance 2.6 from swinging during the up-and-down movement, the transfer mold weight balance 2.6 is positioned on the balance linear guide 2.7 in a manner of moving up and down, and the up-and-down movement of the weight balance 2.6 is performed along the balance linear guide 2.7, so that the up-and-down linear movement of the weight balance 2.6 is ensured without swinging, and the stability of the weight balance 2.6 during the up-and-down movement is increased. Let transfer mould weight balancing piece 2.6 slide from top to bottom along balanced linear guide 2.7, be fixed with balanced slider 2.8 on transferring mould weight balancing piece 2.6, weight balancing piece 2.6 passes through balanced slider 2.8 and can fix a position on balanced linear guide 2.7 with reciprocating to guaranteed the up-and-down rectilinear movement of weight balancing piece 2.6, balanced linear guide 2.7 is also linear guide. The balance slide block 2.8 sliding relatively to the balance linear guide rail 2.7 is a linear slide block. Or the weight balance block 2.6 of the transfer die is sleeved on the linear track to slide up and down.

With the weight balance block 2.6 of the transfer die, the wet blank transfer die 2.1 can vertically move up and down under the driving of the servo motor 2.12 and the guiding action of the linear guide rail 2.4 of the transfer die, so that the requirements of rapidness, stability, accurate positioning and the like can be met.
