It should be noted that: the ejection rod 3 is arranged in various modes, and the end part of the ejection rod can partially extend into the through hole 2 and is not level with the bottom surface of the formed panel; or not extend into the through hole 2, but correspond to the through hole 2 and are flush with the top of the through hole 2, so that the end surface of the ejector rod 3 just shields the top surface of the through hole 2, and the solidified material is prevented from entering the upper part of the molding panel 1, as shown in fig. 2.
Further, another setting mode of the ejection rod is as follows: the ejector rod 3 of the ejector member extends into the through hole 2 and is flush with the surface of the panel 1, as shown in fig. 13, in which the end surface of the ejector rod 3 is flush with the bottom surface of the panel 1. The end face of the ejector rod 3 is separated from the product by lifting the ejector member, and then the ejector member is pressed to cause the ejector rod 3 to pass through the through hole 2 to separate the product from the molded panel 1.
Referring to fig. 1-13, the invention further discloses a device applied to the 3D printer for taking materials, which comprises a forming panel 1, wherein an outer cover 4 is arranged above the forming panel 1, the outer cover 4 and the forming panel 1 are fixed through bolts, ejection members are arranged in the outer cover 4, each ejection member comprises a discharge plate 5 parallel to the forming panel 1, a plurality of ejection rods 3 are arranged on the discharge plates 5 in a penetrating manner, the ejection rods 3 correspond to the through holes 2 in the forming panel 1 one by one, and driving members for starting the ejection members are arranged on the outer cover 4. It should be noted that: the stripper plate 5 is arranged in the housing 4 parallel to the profiled panel and has an area smaller than the profiled panel 1. The ejection rod 3 can be directly fixed on the bottom surface of the discharging plate 5 and can also penetrate through the discharging plate 5, and the ejection rod can be specifically arranged according to actual conditions. In the invention, in order to facilitate installation, the ejection rod 3 adopts a bolt, a hole on the discharging plate is a screw hole, the ejection rod 3 is fixedly connected with the discharging plate 5 through a thread, meanwhile, the side wall of the ejection rod 3 extending out of the lower part of the discharging plate 5 is a smooth surface and is matched with the through hole 2, namely, the ejection rod 3 can just extend into the through hole 2, and the inner wall of the through hole 2 and the outer wall of the ejection rod 3 are polished, so that the gap between the ejection rod and the through hole after the ejection rod extends into the through hole is reduced. Of course, it is understood that the length of the ejector rod is greater than the thickness of the molding panel.
Further, be connected through several connecting rod 6 between top and the shaping panel 1 in the dustcoat 4, connecting rod 6 all runs through stripper 5 to make stripper 5 slide from top to bottom along connecting rod 6. It should be noted that: one end of the connecting rod 6 is fixed on the inner top of the outer cover 4, and the other end can be selectively fixed (can be fixed or can not be fixed) on the top surface of the molded panel 1. The connecting rods 6 are arranged at the four corners close to the discharging plate 5, and the discharging plate can slide up and down along the connecting rods.
Furthermore, a first spring 7 is fixedly sleeved on the connecting rod 6 between the top of the outer cover 4 and the discharging plate 5, and/or a second spring 8 is sleeved on the connecting rod 6 between the discharging plate 5 and the forming panel 1. It should be noted that: the fixed interior top of dustcoat 4 of one end of first spring 7, the other end is fixed on stripper 5, and when setting up of first spring 7 made the stripper move towards the shaping panel, first spring was in by tensile state, when unclamping the external force to the stripper, first spring can take the stripper to reset. And/or, the second spring 8 sleeve is established on the connecting rod between stripper and the shaping panel, and is not fixed with stripper and shaping panel, and certainly also can be fixed, set up according to actual installation condition can. The second spring 8 is compressed when the stripper plate is moved towards the profiled panel and returns with it when the external force on the stripper plate is released. Fig. 2 is a view of the first and second springs in a natural state. As for the arrangement of the first spring and the second spring, only one of them may be arranged, or both of them may be arranged, and it is of course understood that: if two all set up for the ability that the stripper resets is strengthened, can increase the life of spring, avoids long-time the use back, and the elasticity of spring receives the influence, thereby can't make the fine reseing of stripper.
Further: the driving piece is including setting up in dustcoat 4 and the actuating block 9 that corresponds with stripper 5, and the top center department of actuating block 9 is provided with actuating lever 10, and actuating lever 10 stretches out the top of dustcoat 4 and is fixed with fixed head 11, is located dustcoat 4 outside, the cover is equipped with third spring 12 on the actuating lever 10. It should be noted that: a plurality of driving blocks 9 can be arranged according to the size of the outer cover or the molded panel, in the invention, two driving blocks 9 are symmetrically arranged, a fixed shaft 24 of the printer is fixed at the center of the outer cover 4 through a bolt, and the driving blocks 9 are distributed at two sides of the fixed shaft 24. The size of the drive block 9 is set according to the stripper plate 5, which is in principle: the larger the contact surface of the driving plate 9 with the stripper plate 5 or the head of the ejector rod 3, the more stable the stripper plate 5 is moving towards the profiled panel 1, but on the contrary the weight of the driving block 9 increases, which puts a burden on the first spring and/or the second spring, which of course can be solved by changing the material of the driving block 9. Therefore, the material and size of the driving block 9 may be set according to actual conditions. The driving rod 10 and the driving block 9 can be fixed through threaded connection, namely a threaded blind hole is formed in the top of the driving block 9, and the driving rod 10 does not penetrate through the driving block 9. Therefore, the fixing head 11 and the driving rod 10 may be replaced with bolts. The drive rod 10 is arranged at a distance from the housing 4. The third spring 12 can be directly sleeved on the driving rod 10, and both ends of the third spring are not fixed and only contact with the bottom ends of the outer cover and the fixing head. Of course, the fixing can be realized, and the setting mode can be selected according to actual needs.
In use, the third spring 12 is compressed only by pressing the fixed head 11, and the driving rod 10 carries the driving block 9 to move towards the stripper plate 5 until the driving block contacts with the stripper plate 5 or the head of the ejection rod 3; then, the fixing head 11 is continuously pressed, so that the driving block drives the stripper plate to move towards the formed panel until the ejector rod extends into the through hole and extends out of the through hole, and a product on the formed panel is separated from the formed panel.
Further, in order to increase the stability of the driving block when the driving block moves towards the discharging plate, a fixed cylinder 13 matched with the driving block 9 is arranged at the inner top of the outer cover 4, an opening of the fixed cylinder 13 is arranged towards the discharging plate 5, the driving block 9 is positioned in the fixed cylinder 13, the driving rod 10 penetrates through the fixed cylinder 13 and extends out of the outer cover 4, similarly, the driving rod 10 and the fixed cylinder 13 are arranged in a separated mode, a sliding groove 14 is formed in the inner wall of the fixed cylinder 13, and a sliding block 15 matched with the sliding groove 14 is arranged on the side wall of the driving block 9. The slide blocks 15 are arranged on the side wall of the driving block 9 near the top surface thereof, and the number of the slide grooves 14 and the number and size of the slide blocks 15 are determined according to the size of the fixed cylinder 13 and the driving block 9. As shown in fig. 6 and 7, the sliding grooves may be disposed at positions of the fixed cylinder 13 near both ends thereof, and similarly, the sliding blocks 15 are disposed at positions near both ends of the driving block 9, corresponding to and fitting with the sliding grooves. The sliding grooves may be provided on four inner side walls of the fixed cylinder 13, and may be provided only on two corresponding side walls. Therefore, the function of the sliding groove and the sliding block is only to limit the driving block 9 to move up and down along the sliding groove, and the driving block 9 is prevented from inclining during movement. When the driving block 9 is located in the fixed cylinder 13, the bottom surface of the driving block 9 is flush with the bottom surface of the fixed cylinder 13.
Furthermore, in order to limit the travel distance of the driving block towards the stripper plate, an adjusting piece for adjusting the travel of the driving block 9 is arranged on the driving block 9, the adjusting piece comprises a travel cavity 16 arranged in the driving block 9, a first through hole 18 communicated with the travel cavity 16 is arranged at the bottom of the travel cavity 16, a limiting plate 19 with a T-shaped cross section is arranged on the stripper plate 5, and the transverse part of the limiting plate 19 extends into the travel cavity 16 through the first through hole 18. It should be noted that: the vertical part of the limit plate 19 is fixed on the stripper plate 5, and the transverse part is positioned in the running cavity 16 and is in contact with the bottom surface of the running cavity 16, so that the distance between the top of the running cavity 16 and the transverse part of the limit plate 19 is the maximum distance that the driving block 9 can run towards the stripper plate 5. As for the size of the limiting plate 19 and the first through hole 18, there are two setting manners, which can be specifically shown in fig. 8 and 10, and the setting may be specifically performed according to actual needs.
Furthermore, in order to enable the maximum distance of the driving block to run to be adjustable, a threaded hole 17 communicated with the running cavity 16 is formed in the top of the driving block 9, a second through hole 20 communicated with the threaded hole 17 is formed in the outer cover 4 and the fixing cylinder 13 in a penetrating mode, a bolt 21 is arranged in the threaded hole 17, the end portion of the bolt 21 extends into the running cavity 16 and is fixed with a baffle plate 22, the diameter of the second through hole 20 is larger than that of the head portion of the bolt 21, and when the driving block 9 runs towards the discharging plate 5, the bolt 21 can freely move up and down in the second through hole 20. The maximum distance traveled by the driving block 9 is adjusted by screwing the bolts 21 and thus adjusting the position of the baffle 22 projecting into the travel chamber 16, as will be understood: the distance between the baffle plate 22 and the transverse part of the limit plate 19 is the maximum distance for the driving block 9 to run. Therefore, the length of the lateral portion of the stopper plate 19 is required to be set to a certain level. Referring to fig. 9, the length of the lateral portion of the retainer plate 19 is greater than the distance between the two baffles 22, so as to ensure that the lateral portion of the retainer plate 19 contacts the bottom surfaces of the baffles 22 when the drive block moves toward the stripper plate. Referring to fig. 11, the lateral portion of the stopper plate 19 corresponds to the stopper plate 22, so that the lateral portion of the stopper plate 19 contacts the bottom surface of the stopper plate 22 when the driving block is driven toward the stripper plate.
Furthermore, in order to ensure that the two driving rods can simultaneously drive the driving blocks to move towards the stripper plate, the two fixing heads 11 are connected with a connecting frame 23, the shape and the size of the connecting frame 23 are set according to actual needs, and of course, the installation space of the fixing shaft 24 is reserved when the connecting frame 23 is arranged.
When the forming device is used, after a product is formed on the forming panel, a driving mechanism on a printer drives the forming panel and the product on the panel to be separated from the material in the material groove, then the connecting frame 23 is pressed, the third spring 12 is compressed, the two driving blocks 9 simultaneously move towards the discharging plate 5 until the two driving blocks are contacted with the discharging plate 5 or the top end of the ejection rod 3, then the discharging plate is pressed, the first spring is stretched, and/or the second spring 8 is compressed until the ejection rod 3 extends into the through hole 2 and extends out of the through hole 2, and the product is separated from the forming panel.
If the end face of the ejector pin 3 is flush with the bottom surface of the profiled panel 1, the connecting bracket 23 needs to be moved away from the housing 4 to separate the product from the end face of the ejector pin 3, and then the connecting bracket 23 is pressed to separate the product from the profiled panel in the same manner as described above. At this time, it should be noted that: referring to fig. 13, there is a gap between the inner top surface of the fixed cylinder 13 and the top surface of the driving block 9, and the height of the gap is the height at which the driving block 9 can lift the discharging plate 5.
