Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to a moving mechanism for 3D printed plastic products. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology that creates three-dimensional objects by stacking materials layer by layer. Based on digital model files, it builds solid objects by layering materials (such as plastics, metals, resins, etc.), which is in stark contrast to traditional "subtractive manufacturing".

[0003] Among the 3D printing technologies using plastics as raw materials, the following three are common: 1. Fused Deposition Modeling (FDM): The nozzle is heated to melt the filament, which is then extruded and stacked layer by layer. Filament materials include PLA, ABS, PETG, TPU, and nylon. It has advantages such as low cost and simple operation, but the layer texture is obvious, the precision is low, and the support structure needs to be manually removed; 2. Selective Laser Sintering (SLS): Powder particles are sintered by laser and melted layer by layer. Materials include nylon PA12 powder, PA11 powder, and TPU powder. It has advantages such as no need for support structure, ability to manufacture complex geometries, and high strength, but the equipment is expensive, the surface is rough and requires post-processing, and powder recycling is complicated; 3. Multi-Jet Melting: The inkjet head sprays flux, and an infrared lamp heats and melts the powder as a whole. Materials include nylon powder, etc. It has advantages such as fast printing speed, smoother surface, and uniform mechanical properties, but the material selection is limited and the equipment cost is high. Plastic products manufactured through additive manufacturing are generally complex in shape and difficult to move. If operators hold the printed products directly with their hands, they may damage some small parts on the outside of the printed products. In addition, some materials are toxic, and long-term contact with such base products can cause certain harm to the operator's health. Furthermore, some printed products, such as plastic products made by selective laser sintering, are still at a high temperature after processing. In order to continue production, operators need to remove the hot plastic products, which also poses a certain degree of danger. Utility Model Content

[0004] To address the problems of easy damage to 3D printed products during movement and the potential safety hazards to operators in existing technologies, this invention provides a moving mechanism for 3D printed plastic products.

A set of length clamping structures is respectively installed at the head of the first power arm 1 and the second power arm 2. Several clamping protection structures are installed on the inner wall surfaces of both sets of length clamping structures. A limiting structure is provided at the tail of the two grip handles 3. The structure includes: a length adjusting sub-rod 4, a length adjusting main rod 5, a length fixing screw 6, and a clamping mounting plate 7; the length adjusting sub-rod 4 is installed at the head of the first power arm 1, and the upper wall surface of the length adjusting sub-rod 4 has several mounting holes; the length adjusting main rod 5 is movably fitted outside the length adjusting sub-rod 4, and the upper wall surface of the length adjusting main rod 5 has a threaded through hole, the threaded through hole of the length adjusting main rod 5 is aligned with the mounting hole of the length adjusting sub-rod 4; the length fixing screw 6 is installed in the threaded through hole of the length adjusting main rod 5 through the thread, and the length fixing screw 6 passes through the mounting hole of the length adjusting sub-rod 4; the clamping mounting plate 7 is installed at the tail of the length adjusting main rod 5, and the inner wall surface of the clamping mounting plate 7 has several clearance holes.

[0019] As a preferred embodiment, further, the clamping protection structure includes: a protective moving rod 8, a protective return spring 9, a protective baffle 10, and a protective clamping pin 11; the protective moving rod 8 is movably installed in the clearance hole of the clamping mounting plate 7, the protective baffle 10 is installed on the inner wall surface of the protective moving rod 8, the two ends of the protective return spring 9 are respectively installed on the inner wall surface of the clamping mounting plate 7 and the inner wall surface of the protective baffle 10, and the protective return spring 9 is located outside the protective moving rod 8, and the protective clamping pin 11 is installed on the outer wall surface of the protective baffle 10.

[0020] As a preferred embodiment, the limiting structure further includes: two limiting baffles 12 and a limiting spring 13; the two limiting baffles 12 are respectively installed at the tail of the two grip handles 3, and the limiting spring 13 is installed between the two limiting baffles 12.

[0021] As a preferred option, the two grip handles 3 are further provided with an anti-slip rubber layer 14 on the outside.

[0022] As a preferred option, the tail end of the protective clamping pin 11 is further equipped with a soft protective ball 15.

[0023] As a preferred option, the tail end of the protective moving rod 8 is provided with an anti-jamming chamfer.

[0024] Working principle:

[0025] 1. Moving and Printing Plastic Products: The operator holds the two handles 3 with both hands on the outside. The handles 3 are equipped with an anti-slip rubber layer 14 to prevent slippage due to sweaty hands. The operator pulls the handles 3 outwards, increasing the angle between the first power arm 1 and the second power arm 2 about their mounting axes. This also increases the angle between the two sets of length adjusting sub-rods 4 and length adjusting main rods 5, and the distance between the two clamping mounting plates 7. The operator then moves the device to position the printed plastic product between the two clamping mounting plates 7. Finally, the operator pulls their hands inwards... As force is applied, the distance between the two clamping mounting plates 7 decreases until the protective clamping pins 11 and the soft protective balls 15 contact the printed product. The present invention adapts to its shape. The protective clamping pins 11 and the soft protective balls 15 that first contact the product will drive the protective moving rod 8 to move within the clearance hole of the clamping mounting plate 7, and the protective return spring 9 will be compressed. At this point, clamping is completed until most of the protective clamping pins 11 and the soft protective balls 15 can contact the product. The operator can then move the product to the designated position and pull the two gripping handles 3 outward with both hands to place the present invention.

[0026] II. Special Adjustments: According to the size, shape, and material of the printed plastic product, the corresponding parameters of this utility model can be adjusted. When the temperature of the printed product is too high, the size is too large, or the material is toxic, the printed product should be moved as far away from the operator as possible. The operator can move the length adjustment main rod 5 outward to increase the total length of the length adjustment sub-rod 4 and the length adjustment main rod 5, which can protect the operator to a certain extent. When the material density or overall mass of the printed plastic product is too high, the operator can replace the limit spring 13. The larger the elastic coefficient of the limit spring 13, the greater the supporting force it can provide for this utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
