Detailed Description
The idea of the invention is as follows: a sliding column 2.3 for fixing a linear guide rail 2.4 of the transfer mold is adopted to drive a wet blank transfer mold 2.1 to vertically move up and down, and the linear guide rail 2.4 of the transfer mold slides on a transfer slide block 2.5 to guide the up-and-down movement of the wet blank transfer mold; the linear guide rail of the transfer mold can be movably positioned on the transfer slide block 2.5 and can vertically and relatively slide up and down, the structure can ensure the up-and-down movement precision of the wet blank transfer mold, reduce the friction resistance of the up-and-down movement of the wet blank transfer mold 2.1, provide possibility for fast up-and-down movement, and simultaneously improve the up-and-down movement stability of the wet blank transfer mold 2.1 and the positioning precision. The linear guide rail 2.4 of the transfer mould fixed on the sliding column 2.3 is guided by 2 (or more) groups of transfer sliding blocks 2.5 which are vertically separated by a certain distance, so that the vertical movement precision and the operation stability of the sliding column 2.3 can be completely ensured, and the accuracy and the vertical movement stability of the mould closing of the wet blank transfer mould 2.1 and a hot-pressing mould are ensured. The servo motor drives the sliding column 2.3 and the wet blank transfer die 2.1 to move up and down through the transmission of a gear rack or the transmission of a screw pair of a lead screw, so that the up-and-down movement stability and the up-and-down positioning accuracy of the wet blank transfer die 2.1 are greatly improved; the drive of the servo motor can make the wet blank transfer mould 2.1 move accurately and quickly, shorten the period of wet blank transfer and greatly improve the product yield. And the quality of the product can be greatly improved; and the problem that the wet blank is polluted by hydraulic oil is also solved.
Because the wet blank transfer mould and the accessories thereof have certain weight to generate pull-down gravity, larger downward pull force can be generated, which is a power factor for the wet blank transfer mould to slide down out of control and becomes strong resistance for driving the wet blank transfer mould to move upwards by a servo motor. Therefore, the power factor that the wet blank transfer die is out of control and slides down due to the weight of the wet blank transfer die and accessories thereof is completely eliminated; the wet blank transfer die driven by the servo motor with the brake driving slide column 2.3 can completely ensure that the wet blank transfer die does not lose control and slide down.
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, 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 wet blank transfer mould 2.1 can stably and accurately stay at a certain designated 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. 3 and 3.1, the wet blank transfer device 2 includes a wet blank transfer die 2.1, a wet blank transfer die mounting plate 2.2, a slide column 2.3, and a servo motor driving device 2.11 for driving the wet blank transfer die 2.1 and the slide column 2.3 to move up and down.
As shown in fig. 1, 2 and 2.1, a slide column 2.3 is positioned on the upper frame 3 and can vertically slide up and down relative to the upper frame 3, a wet blank transfer die 2.1 is fixed on a wet blank transfer die mounting plate 2.2, a wet blank transfer die mounting plate 2.2 for fixing the wet blank transfer die 2.1 is fixed at one end of the slide column 2.3, and the wet blank transfer die 2.1 can also be directly fixed at one end of the slide column 2.3 without the wet blank transfer die mounting plate 2.2.
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 2.4 fixed on the sliding column 2.3 can slide up and down between the two or more groups of fixed transfer sliders 2.5 separated by a certain distance; or, two or more groups of upper and lower transfer sliders 2.5 fixed on the sliding column 2.3 at a certain distance can slide up and down on a transfer mould 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 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. To overcome this gravity, a transfer mold weight counterbalance 2.6 is provided. As shown in fig. 1, 2, and 3: a group of fixed pulleys (or chain wheels) 2.10 are arranged above the sliding column 2.3, the fixed pulleys (or chain wheels) 2.10 are rotatably positioned on the upper frame, the sliding column 2.3 is positioned on one side of the fixed pulleys (or chain wheels) 2.10, and a weight balance block 2.6 with certain weight for transferring the weight of the mold is positioned on the other side of the fixed pulleys (or chain wheels) 2.10. As shown in fig. 3: a weight balance connecting line (or chain) 2.9 crosses over the fixed pulley (or chain wheel) 2.10 to connect the weight balance weight 2.6 of the transfer mold with the sliding column 2.3, and the weight balance connecting line 2.9 is a flexible rope which can be a rope, a steel cable, a chain and the like. In this way, the weight balance connecting line (or chain) 2.9 hangs the transfer mold weight balance 2.6 and the strut 2.3 on both sides of the fixed pulley (or sprocket) 2.10, respectively, and the transfer mold weight balance 2.6 pulls the strut 2.3 through the weight balance connecting line (or chain) 2.9 across the fixed pulley (or sprocket) 2.10 to realize the gravity of the transfer mold weight balance 2.6 to balance the gravity of the green compact transfer mold 2.1, the strut 2.3 and the green compact transfer mold mounting plate 2.2. Therefore, the sliding column 2.3 and the wet blank transfer die 2.1 can move up and down freely, the up-and-down movement stability of the sliding column 2.3 and the wet blank transfer die 2.1 is effectively improved, the weight balance block of the transfer die can effectively balance the weight of the wet blank transfer die 2.1 and the sliding column 2.3, the risk of the wet blank transfer die 2.1 losing control and sliding down is eliminated, and the gravity load when the wet blank transfer die 2.1 moves up and down is almost eliminated. 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 slide column 2.3, which has been made to slide up and down and is almost in a state of gravity equilibrium, is made by a servomotor drive 2.11; the servo motor driving device 2.11 comprises a rack 2.11-1, a gear 2.11-2 and 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.
