[0002] 3D printers construct three-dimensional models through additive manufacturing methods. Wax-type 3D printers are a type of additive manufacturing equipment. They use phase-change wax as the printing material, spray high-temperature heated wax onto the printing platform, and build the model by stacking layer by layer. After the wax-type 3D printer finishes printing, there is residual waste wax left in the wax cavity and nozzle of the nozzle, which needs to be collected and stored by a collection device to reduce pollution to the table.

[0033] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the collecting mechanism 3 includes a mounting bracket 303, and the bottom of one end of the table panel 2 is slidably connected to the mounting bracket 303, and a collection box 302 is slidably connected to the mounting bracket 303. A through slot 301 is provided on the top side of one end of the table panel 2, and the through slot 301 is located at the top of the collection box 302. The installation of the mounting bracket 303 is conducive to the connection of the collection box 302, and the cooperation of the through slot 301 is conducive to the waste on the head 7 to enter the collection box 302 for storage, thereby realizing waste storage. The sliding connection between the mounting bracket 303 and the bottom of the table panel 2 is conducive to the subsequent cleaning. The mounting bracket 303 drives the collection box 302 to slide out, which is convenient for the staff to pull out the collection box 302 for cleaning, and the operation is more convenient and safe.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, a cylinder 305 is detachably connected to the bottom of one end of the table panel 2, and the output shaft of the cylinder 305 is connected to the center of one end of the mounting bracket 303. Through the installation of the cylinder 305, the cylinder 305 is facilitated to drive and control the mounting bracket 303, so that the mounting bracket 303 can carry the collection box 302 to slide out and retract, which is convenient for waste collection and quick removal and recycling by staff.

[0035] Specifically, such as Figure 4 As shown, symmetrical guide grooves 306 are respectively provided on the inner and outer sides of the top of the mounting frame 303. The mounting frame 303 is slidably connected to the bottom of the table panel 2 through the two guide grooves 306, and the collection box 302 is slidably connected to the inner side of the mounting frame 303 through the two guide grooves 306. The opening of the two groups of guide grooves 306 is beneficial to guiding and positioning the mounting frame 303 and the bottom of the table panel 2, and makes the collection box 302 and the mounting frame 303 slide smoothly and stably.

[0036] Specifically, such as Figure 4 and Figure 5As shown, a handle 304 is installed on the outer wall of one end of the collection box 302, and the inner side of the collection box 302 is a "concave" shaped structure. The width of the top end of the collection box 302 is smaller than the width of the bottom end of the collection box 302. The installation of the handle 304 facilitates the collection box 302 to be taken out and inserted, and the operation is convenient. It is also beneficial to the large space inside the bottom, so that waste is not easily splashed out after entering.

[0037] Specifically, such as Figure 3 、 Figure 5 and Figure 6 As shown, the heating mechanism 4 includes a heating rod 401, and a plurality of equidistantly distributed heating rods 401 are slidably connected to the inner side of the bottom of the collecting box 302, and one end of the plurality of heating rods 401 extends to the outside of the collecting box 302, and the outer wall of one end of the heating rod 401 is threadedly connected to the collecting box 302, and a plurality of equidistantly distributed forming grooves 402 are provided on the inner side of the bottom of the collecting box 302, and the plurality of forming grooves 402 are semicircular structures, and the plurality of forming grooves 402 are arc-shaped structures. The opening of the plurality of forming grooves 402 is conducive to the reception and storage of waste materials, and the operation of the plurality of heating rods 401 is used to heat the bottom of the collecting box 302, which is conducive to the melting of the wax inside the forming groove 402. When the amount of waste materials received increases, the melted wax is formed inside the forming groove 402, which is convenient for subsequent recycling.

[0038] Specifically, such as Figure 5 、 Figure 6 、 Figure 7 and Figure 9As shown, the collection box 302 is provided with a shaking mechanism 5, and the shaking mechanism 5 includes a push plate 501, and the inner side of the other end of the collection box 302 is slidably connected to the push plate 501, and the push plate 501 is slidably connected to the inside of multiple forming grooves 402. Two return springs 503 are connected between one side of the push plate 501 and the inside of the collection box 302, and two ejector rods 502 are vertically connected to one side of the push plate 501. The ejector rods 502 pass through the return springs 503 and extend to the outside of the collection box 302 and contact the mounting frame 303. The ejector rods 502 are slidably connected to the collection box 302. Through the installation of the push plate 501, under the pull of the return springs 503 , causing the baffle to shrink, and when the collection box 302 is inserted into the interior of the mounting frame 303, the push rod 502 on the collection box 302 contacts the inner side of the mounting frame 303, so that the push rod 502 drives the push plate 501 to slide out. When the wax is formed inside the molding groove 402, the collection box 302 is pulled out, and the push rod 502 is separated from the mounting frame 303. At this time, the push plate 501 slides under the pull of the reset spring 503, so that the push plate 501 is separated from the end of the wax mold. By repeatedly sliding and colliding the collection box 302 and the mounting frame 303, the push plate 501 is repeatedly loosened against the wax mold for easy recovery.

[0039] Specifically, such as Figure 4 、 Figure 6 and Figure 8 As shown, a locking mechanism 6 is installed on the collection box 302, and the locking mechanism 6 includes a locking slot 601. A locking slot 601 is provided at the bottom of one end of the mounting frame 303. A limiting rod 602 is installed at the inner midline of one end of the collection box 302. The limiting rod 602 is slidably connected to the inner side of the collection box 302 through two compression springs 603. The bottom of the limiting rod 602 extends to the outside of the collection box 302 and engages with the locking slot 601. The top of the limiting rod 602 extends to the outside of the top of the collection box 302 and contacts the bottom of the table panel 2. Through the installation of the limiting rod 602, under the contact of the table panel 2, the limiting rod 602 The positioning rod 602 breaks away from the elastic force of the compression spring 603 and slides down, and the limiting rod 602 is inserted into the locking groove 601 to limit the collection box 302 and the mounting bracket 303, so that the collection box 302 does not fall when the mounting bracket 303 slides. After the collection box 302 is pushed out by the mounting bracket 303, the top of the limiting rod 602 on the collection box 302 is separated from the table panel 2, and the limiting rod 602 rises under the resistance of the compression spring 603 without external force, thereby separating from the locking groove 601 and releasing the limit, making it easy to extract and recycle the collection box 302.

[0040] Specifically, such as Figure 8As shown, the top of the limiting rod 602 is rotatably connected to a pressure wheel 604, and the pressure wheel 604 is in conflict with the bottom of the table panel 2. The bottom of the limiting rod 602 is a trapezoidal structure. Through the installation of the pressure wheel 604, it is beneficial to guide and reduce wear when the limiting rod 602 conflicts with the table panel 2, and it is convenient for the limiting rod 602 to be smoothly inserted into the lock slot 601.

[0041] When the present invention is in use, first, the installation of the mounting frame 303 is facilitated to connect the collection box 302, and the cooperation of the through slot 301 is facilitated to enable the waste on the head 7 to enter the collection box 302 for storage, realizing waste storage, and the sliding connection between the mounting frame 303 and the bottom of the table panel 2 is facilitated for subsequent cleaning, and the mounting frame 303 drives the collection box 302 to slide out, which is convenient for the staff to pull out the collection box 302 for cleaning, and the operation is more convenient and safe. The installation of the cylinder 305 is conducive to the cylinder 305 driving the mounting frame 303, so that the mounting frame 303 carries the collection box 302 to slide out and retract, which is convenient for waste collection and the staff to quickly take out and recycle. The opening of the handle 304 is conducive to guiding and positioning the mounting frame 303 and the bottom of the table panel 2, and makes the collection box 302 and the mounting frame 303 slide smoothly and stably. The installation of the handle 304 is conducive to taking out and inserting the collection box 302, which is easy to operate and has a large space inside the bottom, so that waste is not easy to splash out after entering. The opening of multiple molding grooves 402 is conducive to receiving and storing waste, and the operation of multiple heating rods 401 can achieve heating of the bottom of the collection box 302, which is conducive to melting the wax inside the molding groove 402. When the amount of waste received increases, the melted wax is formed inside the molding groove 402, which is convenient for subsequent recycling. The installation of the push plate 501 is conducive to the reset spring The push plate 501 is pulled out by the spring 503 to shrink the baffle. When the collection box 302 is inserted into the mounting bracket 303, the top rod 502 on the collection box 302 conflicts with the inner side of the mounting bracket 303, causing the top rod 502 to drive the push plate 501 to slide out. When the wax is formed inside the molding groove 402, the collection box 302 is pulled out and the top rod 502 is separated from the mounting bracket 303. At this time, the push plate 501 slides under the pull of the return spring 503, causing the push plate 501 to separate from the end of the wax mold. By repeatedly sliding and colliding the collection box 302 and the mounting bracket 303, the push plate 501 is repeatedly loosened against the wax mold for easy recovery. By installing the limit rod 602, the limit rod 602 is freed from the compression spring under the conflict of the table panel 2. The elastic force of 603 slides down, and the limit rod 602 is inserted into the lock groove 601 to limit the collection box 302 and the mounting bracket 303, so that the collection box 302 does not fall when the mounting bracket 303 slides. After the collection box 302 is pushed out with the mounting bracket 303, the top of the limit rod 602 on the collection box 302 is separated from the table panel 2. The limit rod 602 rises under the resistance of the compression spring 603 without external resistance, and is separated from the lock groove 601 to release the limit, which is convenient for extracting and recycling the collection box 302. The installation of the pressure wheel 604 is beneficial to the conflict between the limit rod 602 and the table panel 2, which plays a role of guiding and reducing wear, and facilitates the smooth insertion of the limit rod 602 into the lock groove 601.
