Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a device for removing impurities from shoe mold 3D printing consumables. Background Art

[0002] A 3D printer is a machine using rapid prototyping technology. It is a technology that uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer based on digital model files. In terms of shoe mold making, 3D printing technology breaks the limitations of design and can quickly and easily print fine and complex patterns and curved surfaces with obvious details, higher precision and better surface finish. When printing shoe mold parts, it reduces labor costs, improves mold making efficiency, and can produce complex structures that traditional processes cannot produce. It can be formed in one piece, and even small batches can be produced with high quality and speed.

[0003] When performing 3D printing of shoe molds, it is necessary to remove impurities from the raw materials to obtain materials that can be used for printing. Nowadays, the raw materials commonly used for 3D printing shoe molds are powdered raw materials and fibrous raw materials. When the raw materials are fed into the 3D printer, there will be large impurities in the raw materials. Fibers and powdered raw materials are easy to adhere, which can easily cause the machine to jam during printing. The existing device sets a filter and uses gravity to make the raw materials pass through the filter to remove impurities. However, this method of screening and removing impurities takes a long time, and the impurities after the raw materials adhere to the raw materials are large in volume and easily block the filter holes, affecting the efficiency of raw material filtration. In order to solve this problem, we propose a shoe mold 3D printing consumables impurity removal device. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In the existing device, after the user pours the raw materials required for shoe mold 3D printing into the screening box, under the action of gravity, the raw materials move downward on the filter screen inside the screening box, metal powder and plastic fiber parts pass through the filter holes, and impurities are excluded on the filter screen.

[0040] The related technology sets a filter and uses gravity to make the raw materials pass through the filter to remove impurities. However, this method takes a long time to screen and remove impurities, and the impurities attached to the raw materials are large in volume and easily block the filter holes, affecting the efficiency of raw material filtration.

[0041] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a shoe mold 3D printing consumables impurity removal device. When it is needed, the raw materials only need to be poured into the interior of the box body 11 from the feed port 13, and then the motor 22 is turned on to make the shift block 221 push the top plate 222, so that the filter screen 15 vibrates synchronously, and the initial screening work of the filter screen 15 is accelerated. The screened metal powder and plastic fiber parts slide on the filter screen 241. Because the filter holes of the filter screen 241 can only pass metal powder, the plastic fiber parts can be discharged directly, and the metal powder falls onto the slide plate 25 and then is discharged from the discharge port 14.

[0042] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0043] Combination Figure 1-Figure 4 The embodiment of the present application provides a shoe mold 3D printing consumables impurity removal device, including an impurity removal device 1; the impurity removal device 1 includes: a universal wheel 12 is arranged at the bottom of a box body 11; a feed port 13 is arranged on the box body 11; a discharge port 14 is arranged on the box body 11; a filter screen 15 is arranged inside the box body 11 and the filter screen 15 and the box body 11 are slidably connected; a screening device 2 is arranged on the impurity removal device 1, and the screening device 2 includes: a box body 21 is arranged on the box body 11, a motor 22 is arranged on the box body 21, a shift block 221 is fixedly connected to the output end of the motor 22, and the shift block 221 and the filter screen 15 are movably connected through a top plate 222; a frame 24 is arranged at the bottom of the filter screen 15, and a filter screen 241 is arranged on the frame 24; a slide plate 25 is arranged at the bottom of the filter screen 241.

[0044] 3D printing shoe molds require screening of raw materials. The raw materials of the shoe molds contain metal powder, plastic fiber parts and other impurities. The user pours the raw materials from the feed port 13. After the raw materials reach the filter screen 15, the motor 22 is started. The output end of the motor 22 is fixedly connected to the shift block 221. The shift block 221 is a fixed block with a protrusion at one end. The shift block 221 pushes the top plate 222. The top plate 222 has a groove that matches the shift block 221. Therefore, the top plate 222 is controlled by the shift block 221 to vibrate up and down. Through the vibration of the top plate 222, the filter screen 15 vibrates synchronously, so that larger impurities remain on the filter screen 15. A block is set on the filter screen 15. During the vibration of the filter screen 15, the block will block the gap at the connection between the filter screen 15 and the top plate 222 to prevent impurities from entering the gap and vibrating. The metal powder and plastic fiber pieces required for shoe mold production are filtered out from the filter screen 15 and fall into the filter screen 241, completing the preliminary separation of the raw materials. After the initial screening, the box door behind the box body 11 can be opened to clean the filter screen 15. The metal powder and plastic fiber pieces after the initial screening will be mixed together on the filter screen 241. Under the action of gravity, the metal powder and plastic fiber pieces slide on the filter screen 241. Through the action of friction, the metal powder passes through the filter screen 241 and falls onto the slide plate 25, and is finally discharged from the discharge port 14. The plastic fiber pieces move along the filter screen 241 to the baffle 26 under the action of gravity. The plastic fiber pieces can be discharged by opening the baffle 26. The specific mesh number and filter hole size of the filter screen 15 and the filter screen 241 are customized according to the on-site material rules.

[0045] In some embodiments, a spring 23 is provided on the top plate 222, and a damping pad 231 is provided on the spring 23. When the shift block 221 pushes the top plate 222, vibration is generated. The spring 23 and the damping pad 231 are provided to reduce the vibration of the box body 11, thereby improving the stability of the top plate 222 during vibration and extending the service life of the entire device.

[0046] In some embodiments, the second filter screen 241 and the slide plate 25 are inclined. After the initial separation, the raw materials fall onto the second filter screen 241 and the slide plate 25, and slide downward along the inclined surface under the action of gravity. The inclined surface can accelerate the discharge process of the entire device.

[0047] In some embodiments, the filter holes of the second filter 241 are smaller than those of the first filter 15. The raw materials for making the shoe mold include plastic fiber parts and metal powder, both of which have different volumes and can pass through the first filter 15. The plastic fiber parts are too large to pass through the second filter 241, and the metal powder can pass through the second filter 241 to the slide plate 25.

[0048] In some embodiments, the frame 24 is provided with a pulley 242, the box 11 is provided with a slide 245, and the pulley 242 and the slide 245 are slidably connected. The plastic fiber piece is relatively large and is easily stuck when sliding on the second filter screen 241. The user can pull out the frame 24 by a handle to expose the second filter screen 241. The height of the frame 24 is higher than the second filter screen 241, so the plastic piece on the second filter screen 241 will not splash out of the second filter screen 241 into the slide 245 to get stuck on the pulley 242, so that the plastic fiber piece stuck on the second filter screen 241 can be processed and the device can continue to work.

[0049] In some embodiments, a magnetic block 243 is provided at the connection between the frame 24 and the back of the box 11. The magnetic block 243 is divided into two pieces, positive and negative, one piece is at the back of the frame 24, and the other piece is at the back of the box 11. Under the action of magnetic attraction, the frame 24 and the box 11 are connected together. The magnetic attraction force is smaller than the user's manpower, and the frame 24 can be pulled out quickly.

[0050] In some embodiments, a limit block 244 is provided on the frame 24. The limit block 244 is provided at the rear end of the frame 24 and moves with the frame 24. A stop block is provided on the box body 11. The limit block 244 abuts against the stop block when the frame 24 is pulled out to the maximum distance to prevent the frame 24 from dislocating.

[0051] In some embodiments, a baffle 26 is rotatably connected to the box body 11. The box body 11 at the outlet of the second filter screen 241 is an empty slot, and a rotating shaft is provided on the top thereof, and the baffle 26 is rotatably connected to the rotating shaft, so that the user can pull the baffle 26 open through the handle on the baffle 26. When it is not necessary to take out the plastic fiber piece, the baffle presses against the outlet of the second filter screen 241 under the action of gravity, so that the outlet is isolated to prevent impurities from being blown into the box body 11 from the outside.
