Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and in particular to a 3D printing equipment with a waste cleaning structure. Background Technology

[0002] 3D printing equipment is a device that creates three-dimensional objects by adding materials layer by layer. It uses a cumulative manufacturing technique, which means that materials are stacked one after another according to instructions in computer graphics data, ultimately forming a complete three-dimensional object.

[0003] A search revealed a utility model patent in China with patent publication number CN219769111U, disclosing a 3D printing device belonging to the field of printing technology. This 3D printing device includes a base, with a lifting mechanism fixedly installed above the base. The lifting mechanism includes a first motor fixedly installed above the base, a first lead screw connected to the bottom end of the first motor, a slide rod fixedly installed above the base, a threaded sleeve threadedly connected to the first lead screw, and a worktable slidably connected to the slide rod. This utility model achieves cooling of the feed pipe by using a cooling block installed above the feed pipe and a cooling pipe on its outer wall. The cooling block contains coolant, which flows into the cooling pipe and surrounds the outer wall of the feed pipe. By providing a detachable feed inlet and nozzle, when changing to other materials for 3D printing, the feed inlet and nozzle matching the material can be replaced individually, thus reducing the frequency of replacing the entire component.

[0004] The aforementioned patent addresses the cooling of the nozzle in 3D printing equipment, but it fails to clean the printing table. If there are residues on the printing table, such as plastic residue, glue, or other adhesives left from the previous print, they may interfere with the new printing task. These residues may affect the adhesion of the printing material, causing the printed part to move or deform during the printing process, thereby reducing the print quality. Utility Model Content

[0011] Preferably, a motor is fixedly connected to the side wall of the bracket, a rod is rotatably connected inside the bracket, the end of the rod is fixedly connected to the output end of the motor, and the rod is threadedly connected to the plate.

[0012] Preferably, a crossbar is fixedly connected inside the bracket, the crossbar is slidably connected through the plate, and two guide rods are slidably connected through the plate, the lower end of the guide rods being fixedly connected to the upper end of the movable plate.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. After the printed object is removed from the top of the printing table, because the material is heated and printed on the top of the printing table, some material will stick to the top of the printing table after printing. Before printing the next object, the residue on the top of the printing table needs to be cleaned. The screw is driven by a servo motor to rotate, causing the movable frame to slide back and forth. The movable frame drives the scraper to slide laterally, so that the lower end of the scraper contacts the top of the printing table. The scraper cleans the residue on the top of the printing table by sliding laterally, keeping the top of the printing table clean and avoiding problems such as uneven printing or printing failure caused by residue, thereby improving the printing quality.

[0015] 2. The residue scraped off the top of the printing table is pushed to the top of the slot by the scraper. The residue falls into the collection frame through the slot and is collected and processed in a centralized manner, which prevents the residue from accumulating on the top of the base, thus keeping the working area of ​​the 3D printing equipment clean and orderly.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A 3D printing device with a waste cleaning structure includes a base 001, a printing table 101 at the upper end of the base 001, two grooves 102 at the upper end of the base 001, a support 003 at the upper end of the base 001, the end of the support 003 being slidably connected to the grooves 102, and two sliding grooves 104 at the upper end of the base 001; a movable frame 002, located at the upper end of the base 001, with its lower end slidably connected to the sliding grooves 104, and a scraper 2 at the top of the movable frame 002. 01; Plate 004, plate 004 is located inside the upper end of the bracket 003. An electric actuator 401 is fixedly connected to the upper end of plate 004. A movable plate 403 is located at the lower end of plate 004. The upper end of the movable plate 403 is fixedly connected to the output end of the electric actuator 401. A print head 404 is located at the lower end of the movable plate 403. The bracket 003 drives plate 004 to slide back and forth, i.e., the print head 404 slides back and forth. The groove 102 guides and limits the sliding bracket 003, and then the plate 004 drives the movable plate 401 to slide back and forth. 3. The print head 404 slides left and right, while the movable plate 403 slides up and down via the electric actuator 401. When an object needs to be printed, material is fed into the print head 404. Based on the data and instructions of the 3D printing model, the movement trajectory and extrusion speed of the print head 404 are controlled to stack the material layer by layer on the printing table 101, ultimately constructing the desired 3D object. After the object is printed, the operator removes the printed object from the printing table 101. The top is removed because the material is heated and printed on the top of the printing table 101. Therefore, after the object is printed, some material will stick to the top of the printing table 101. Before printing the next object, the residue on the top of the printing table 101 needs to be cleaned. At this time, the movable frame 002 drives the scraper 201 to slide horizontally, so that the lower end of the scraper 201 contacts the top of the printing table 101. The scraper 201, which slides horizontally, cleans the residue on the top of the printing table 101, keeping the top of the printing table 101 clean.

[0024] A hydraulic cylinder 103 is fixedly connected inside the side wall of the base 001. The output end of the hydraulic cylinder 103 is fixedly connected to the side wall of the bracket 003. The bracket 003 is pushed or pulled back and forth by the hydraulic cylinder 103.

[0025] A servo motor 105 is fixedly connected to the side wall of the base 001. A screw 106 is rotatably connected inside the slide groove 104. The end of the screw 106 is fixedly connected to the output end of the servo motor 105. The screw 106 is threadedly connected to the movable frame 002. The servo motor 105 drives the screw 106 to rotate, causing the movable frame 002 to slide back and forth.

[0026] The upper end of the base 001 is provided with a slot 107, which is located on one side of the printing table 101. A collection frame 108 is slidably connected through one side of the base 001. The collection frame 108 is located below the slot 107. The residue scraped off the upper end of the printing table 101 is pushed to the upper part of the slot 107 by the scraper 201. The residue falls into the collection frame 108 through the slot 107 and is collected and processed centrally by the collection frame 108.

[0027] A motor 301 is fixedly connected to the side wall of the bracket 003. A rod 302 is rotatably connected inside the bracket 003. The end of the rod 302 is fixedly connected to the output end of the motor 301. The rod 302 is threadedly connected to the plate 004. The motor 301 drives the rod 302 to rotate, so that the plate 004 slides laterally left and right inside the upper end of the bracket 003.

[0028] A crossbar 303 is fixedly connected inside the bracket 003. The crossbar 303 is slidably connected to the plate 004. Two guide rods 402 are slidably connected inside the plate 004. The lower end of the guide rod 402 is fixedly connected to the upper end of the movable plate 403. The crossbar 303 guides and limits the left and right sliding plate 004, and the guide rods 402 guide and limit the longitudinally sliding movable plate 403.

[0029] In this invention, when an object needs to be printed, the material is fed into the print head 404. According to the data and instructions of the 3D printing model, the hydraulic cylinder 103 pushes or pulls the support 003 to slide back and forth, that is, the print head 404 slides back and forth. Then, the motor 301 drives the rod 302 to rotate, so that the plate 004 slides horizontally left and right inside the upper end of the support 003, that is, the print head 404 slides left and right. The electric push rod 401 pushes or pulls the movable plate 403 to slide up and down, that is, the print head 404 slides up and down. By controlling the movement trajectory and extrusion speed of the print head 404, the material is stacked layer by layer on the printing table 101, and finally the required 3D object is constructed.

[0030] After the object is printed, the operator removes the printed object from the top of the printing table 101. Because the material is heated before printing on the top of the printing table 101, some material will stick to the top of the printing table 101 after printing. Before printing the next object, the residue on the top of the printing table 101 needs to be cleaned. The servo motor 105 drives the screw 106 to rotate, causing the movable frame 002 to slide back and forth. The movable frame 002 drives the scraper 201 to slide laterally, so that the lower end of the scraper 201 contacts the top of the printing table 101. The scraper 201, which slides laterally, cleans the residue on the top of the printing table 101, keeping the top of the printing table 101 clean.

[0031] The residue scraped off the top of the printing table 101 is pushed to the top of the slot 107 by the scraper 201. The residue falls into the collection frame 108 through the slot 107 and is collected and processed in a centralized manner by the collection frame 108 to prevent the residue from accumulating on the top of the base 001.
