[0029] Example 1: Refer to Figures 1-5This is the first embodiment of the present invention, which provides a 3D printed product post-processing polishing device. Most polishing devices on the market currently rely on operators manually holding the 3D printed product to polish it against a polishing roller. This manual method poses safety hazards, and existing polishing devices cannot collect the polishing debris, causing environmental pollution. The device includes a housing 1, with a U-shaped baffle 2 installed at the top. A mounting bracket 3 is installed on one side wall, and a drive assembly 301 is installed inside the mounting bracket 3.

[0030] Combination Figure 1 , Figure 2 and Figure 3 In this embodiment of the utility model, a sliding groove 501 is provided at the top of the U-shaped frame body 5, and a crossbar body 502 is fixedly installed on the side walls at both ends of the sliding groove 501. A handle body 503 is installed on one side wall of the U-shaped frame body 5, and a protective sleeve is installed on the outer wall of the handle body 503.

[0031] Combination Figure 1 , Figure 2 and Figure 3 In an embodiment of this utility model, the positioning and fixing mechanism 6 includes a mounting frame 601. A second mounting block 606 is mounted on the bottom end of the mounting frame 601, and the second mounting block 606 cooperates with the slide groove 501. The interior of the second mounting block 606 cooperates with the crossbar body 502. A slide rail 602 is mounted on the side wall of one end of the interior of the mounting frame 601, and a slider 603 is provided inside the slide rail 602. A pressing plate 604 is mounted on the end of the slider 603 away from the slide rail 602. The extrusion plate 604 has a first through hole 6041 and a threaded hole body 6042 respectively. An anti-slip pad 6043 is installed at one end of the extrusion plate 604 that is close to each other. The top of the mounting frame 601 is rotatably mounted with a bolt rod body 605 that passes through the threaded hole body 6042 via a bearing. The top and bottom of the mounting frame 601 are fixedly mounted with anti-slip pads 6043 that pass through the first through hole 6041, and the anti-slip pads 6043 and the first through hole 6041 cooperate with each other.

[0032] The specific working principle is as follows: When it is necessary to position and fix the 3D printed product, the bolt rod body 605 is first threadedly connected to the threaded hole body 6042, and the slide rail 602 and the slider 603 cooperate with each other, and the first through hole 6041 and the anti-slip pad 6043 cooperate with each other, so that when the bolt rod body 605 rotates, it can drive the two sets of extrusion plates 604 to rise and fall in opposite directions on the outer wall of the bolt rod body 605. This facilitates the positioning and fixing of the 3D printed product when the two sets of extrusion plates 604 rise and fall in opposite directions. At the same time, the second mounting block 606 cooperates with the crossbar body 502, so that the positioning and fixing mechanism 6 can slide on the outer wall of the crossbar body 502 through the second mounting block 606. At the same time, the rectangular groove 4 cooperates with the mounting block body 401, so that the sliding of the U-shaped frame body 5 can drive the mounting block body 401 to slide inside the rectangular groove 4. Thus, the 3D printed product and the grinding roller body 303 are ground by sliding the U-shaped frame body 5 and the positioning and fixing mechanism 6.

[0033] Example 2: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a 3D printed product post-processing polishing device, which can realize the problem that most polishing devices on the market currently rely on operators to hold the 3D printed product and polish it with the polishing roller during post-processing of 3D printed products. This manual method is prone to safety hazards. At the same time, existing polishing devices cannot collect the debris generated during polishing, thus causing pollution to the surrounding environment. The bottom end of the U-shaped baffle 2 is provided with a feeding hopper 201, and the bottom end of the feeding hopper 201 is equipped with a feeding pipe 202.

[0035] The specific working principle is as follows: when it is necessary to collect the debris generated during the grinding of 3D printed products, the design of the fan body 203 is used to generate suction in the hopper 201 by activating the fan body 203. At the same time, the design of the storage box 702 and the rectangular hole 7021 allows the debris generated during grinding to be sucked into the rectangular hole 7021 by the suction generated by the hopper 201. The design of the storage box 702 prevents the debris from splashing during collection. The storage box 702 and the storage slot 701 cooperate with each other, so that the storage box 702 can be taken out by opening the door panel body 7.
