Description

Technical Field

[0001] The present application relates to the field of 3D printing technology, and in particular to a 3D printing wire production and blanking device. Background Art

[0002] Fused Deposition Modeling (FDM) is a major 3D printing technology. It heats and melts a hot-melt filament, extruding it from a nozzle and depositing it onto the print platform or a previously solidified layer of material. When the temperature drops below the filament's solidification temperature, it begins to solidify and form, ultimately creating a solid object.

[0003] The base color of the final molded product is determined by the color of the wire, so corresponding colored wires are required in some colored 3D printing products. In the production of colored 3D printing wires, masterbatches and raw materials are generally added to the extruder; the traditional method uses manual feeding, which is time-consuming and labor-intensive, and requires high labor costs; to address this problem, some automatic feeding machines have begun to appear on the market, which can realize timed automatic feeding and alleviate manpower pressure, but during use, it was found that the extrusion speed of the extruder and the feeding speed cannot maintain absolute synchronization. After a period of startup, there will be an error between the two, and the error will gradually increase with time. In one case, the extrusion speed of the extruder is too high, and the feeding cannot keep up. At this time, the extruder will have a raw material fault, affecting the normal production of the product. If the feeding speed is too fast, the material will accumulate at the feed port of the extruder and gradually accumulate, eventually affecting the normal feeding of the feeding machine. Utility Model Content

[0004] The purpose of this application is to provide a 3D printing wire production blanking device to solve at least one of the above technical problems.

[0005] In order to solve the above technical problems, the present application provides a 3D printing wire production unloading device, including a storage bin, a material distribution component, a leakage bin, a material guide component and an extruder;

[0006] The storage bin is used to store materials, the material dividing assembly is provided between the storage bin and the leakage bin and allows a quantitative amount of material in the storage bin to pass through and enter the leakage bin, and the material guiding assembly is provided between the leakage bin and the extruder feed port and is used to guide the material in the leakage bin to enter the extruder;

[0007] The material guide assembly includes a fixing base fixed on the extruder, a first mounting hole coaxially arranged with the extruder is provided on the fixing base, a first tube body is provided on the first mounting hole, and a first funnel is provided at one end of the first tube body close to the leakage bin;

[0008] The first tube is a transparent tube;

[0009] In the above implementation process, the staff can put more materials into the storage bin at one time, and the materials will be quantitatively leaked into the leakage bin through the dividing component, and the materials in the leakage bin will further enter the extruder through the guiding component; the guiding component includes a fixed seat and a first tube body, and the fixed seat keeps the first tube body stable, and the materials will quantitatively pass through the leakage bin and then enter the transparent first tube body, and the first tube body plays the role of material buffering. When the extruder is working, when the extrusion speed is slightly greater than the material discharge speed, the staff can observe through the transparent first tube body that the height of the material accumulated in the transparent tube body is getting lower and lower. When it reaches a certain height, the speed of the dividing component can be appropriately adjusted to improve the efficiency of the leakage, so that the materials buffered in the transparent first tube body can be kept at a certain height. The material height no longer decreases; similarly, when the leakage speed is high, the staff can observe through the transparent first tube that the height of the material is getting higher and higher. When it reaches a certain height, the staff can choose to adjust the efficiency of the material distribution component; it is understandable that this solution is based on the actual premise that there are working errors. The adjustment is made under the premise that there are working errors. That is, in actual applications, although a quantitative feeding device can be used to achieve timed and quantitative feeding, there will still be errors and the error accumulation will increase over time. This solution cleverly adds a material guide component to achieve material caching, so that the staff can observe the accumulated errors in time and make timely adjustments to avoid excessive material accumulation or insufficient material supply, thereby ensuring the smooth progress of the extrusion process.

[0010] Preferably, the material distribution assembly includes two material leakage plates, a turntable rotatably arranged between the two material leakage plates, and a rotary drive member for driving the turntable to rotate;

[0011] The leakage plate is provided with a first leakage hole group, which is provided with multiple groups and distributed at equal angles around its axis; the turntable is provided with a second leakage hole group, and when the through holes of the first leakage hole group are connected with the through holes of the second leakage hole group, the material is suitable for entering the leakage bin from the storage bin;

[0012] In the above implementation process, the turntable is rotatably set between the two leakage plates. Only when the second leakage hole group of the turntable is rotated to connect with the first leakage hole group of the upper and lower leakage plates, the material will enter the leakage bin from the storage bin. The rotation speed of the turntable is constant, so timed intermittent leakage can be achieved during the rotation process.

[0013] Preferably, the material storage bin is provided with a first material separator and a second material separator, the first material separator extends along the radial direction of the material storage bin and a plurality of the first material separators are distributed at equal angles, and the second material separator is annular and is divided into an inner ring area and an outer ring area;

[0014] Preferably, the inner ring area is used for loading masterbatch; the outer ring area is used for loading raw materials;

[0015] In the above implementation process, this solution utilizes the first material separator and the second material separator to separate the storage bin into multiple areas, wherein multiple areas are formed near the inner ring area under the separation effect of the first material separator for loading the same or different masterbatches, and multiple areas are formed in the outer ring area under the separation effect of the first separator for loading the same or different raw materials. In this way, the staff can fill appropriate materials in different areas according to actual needs to better adapt to the actual production situation.

[0016] Preferably, the number of the first leakage hole groups is the same as the number of the first separator plates;

[0017] The first leakage hole group includes a first through hole and a second through hole, the first through hole is located in the inner ring area, and the second through hole is located in the outer ring area;

[0018] The second leakage hole group includes a third through hole and a fourth through hole, the first through hole is located on the moving path of the third through hole, and the second through hole is located on the moving path of the fourth through hole;

[0019] Preferably, the first through hole and the second through hole are located on the same radial line of the leakage disk; the third through hole and the fourth through hole are not located on the same radial line of the rotating disk;

[0020] Wherein, when the third through hole is connected to the first through hole, the fourth through hole is not connected to the second through hole;

[0021] In the above implementation process, the third through hole and the fourth through hole on the turntable are staggered. When the turntable rotates, the first through hole is connected with the third through hole, and the masterbatch passes through the first through hole of the upper leakage disk and then enters the third through hole and then passes through the first through hole of the lower leakage disk into the leakage bin. It can be understood that at this time, the second through hole and the fourth through hole are not connected, so only the masterbatch completes the unloading; similarly, as the turntable rotates, the second through hole is connected with the fourth through hole. At this time, the raw material is unloaded, but the masterbatch cannot be unloaded, so that the sequential unloading of masterbatch and raw material can be achieved.

[0022] Preferably, the rotary drive member includes a first gear and a rotary motor suitable for driving the first gear to rotate, and teeth are provided on the outer periphery of the turntable, and the first gear meshes with the teeth to drive the turntable to rotate;

[0023] In the above implementation process, the rotating motor drives the first gear to rotate. Teeth are provided on the outer periphery of the turntable, and meshing with the first gear is achieved through the teeth. Therefore, when the first gear rotates, the turntable can be driven to rotate.

[0024] Preferably, the first tube body includes a first segment close to the leakage bin, a second segment close to the extruder, and a third segment located between the first segment and the second segment; the third segment is detachably connected to the first segment and the second segment respectively;

[0025] Preferably, the third segment is provided with multiple segments and is detachably connected;

[0026] In the above implementation process, the first tube body in this solution is detachably connected by a multi-section structure, so in actual application, the length of the first tube body can be adjusted according to actual needs; at the same time, in subsequent maintenance, if part of the tube body is damaged, the damaged part can be replaced without replacing the entire tube body, effectively reducing maintenance costs.

[0027] Preferably, the leakage bin is funnel-shaped;

[0028] In the above implementation process, the leakage bin is funnel-shaped, so that the leaked materials can be better concentrated at the inlet of the first tube body.

[0029] Compared with the prior art, the beneficial effect of the present application is that: this scheme is based on the actual premise that there are working errors for adjustment, that is, in actual applications, although a quantitative feeding device can be used to achieve timed quantitative feeding, there will still be errors and the errors will accumulate and increase over time. This scheme cleverly adds a material guide component to achieve material caching, so that the staff can observe the accumulated errors in time and make timely adjustments to avoid excessive material accumulation or insufficient material supply, thereby ensuring the smooth progress of the extrusion process.

[0039] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0040] Example: In some color 3D printing products, corresponding color lines are required. In the production of color 3D printing lines, masterbatches and raw materials are generally added to the extruder; the traditional method uses manual feeding, which is time-consuming and labor-intensive, and requires high labor costs; to address this problem, some automatic feeding machines have begun to appear on the market, which can realize timed automatic feeding and relieve manpower pressure, but during use, it is found that the extrusion speed of the extruder and the feeding speed cannot maintain absolute synchronization. After a period of startup, there will be an error between the two, and the error will gradually increase with time. In one case, the extruder extrusion speed is too high, and the feeding cannot keep up. At this time, the extruder will have a raw material fault, affecting the normal production of the product. If the feeding speed is too fast, the material will accumulate at the feed port of the extruder and gradually accumulate, eventually affecting the normal feeding of the feeding machine; in order to solve the above technical problems, this embodiment provides the following technical solutions:

[0041] For details, see Figure 1-4 , this embodiment provides a 3D printing wire production unloading device, including a storage bin 10, a material distribution component 20, a leakage bin 30, a material guide component and an extruder 50;

[0042] Specifically, the storage bin 10 is used to store materials, the material distribution component 20 is provided between the storage bin 10 and the leakage bin 30 and allows the material in the quantitative storage bin 10 to pass through to enter the leakage bin 30, and the material guide component is provided between the leakage bin 30 and the feed inlet of the extruder 50 to guide the material in the leakage bin 30 into the extruder 50;

[0043] Furthermore, the material guide assembly includes a fixing base 421 fixed on the extruder 50, a first mounting hole coaxially arranged with the extruder 50 is provided on the fixing base 421, a first tube 40 is provided on the first mounting hole, and a first funnel 411 is provided at one end of the first tube 40 close to the leakage bin 30;

[0044] Wherein, the first tube 40 is a transparent tube;

[0045] In the above scheme, the staff can put more materials into the storage bin 10 at one time, and the materials will be quantitatively leaked into the leakage bin 30 through the material dividing component 20, and the materials in the leakage bin 30 will further enter the extruder 50 through the material guiding component; the material guiding component includes a fixed seat 421 and a first tube body 40, and the fixed seat 421 keeps the first tube body 40 stable, and the materials will quantitatively pass through the leakage bin 30 and then enter the transparent first tube body 40, and the first tube body 40 plays the role of material buffering. When the extruder 50 is working, when the extrusion speed is slightly greater than the material discharge speed, the staff can observe through the transparent first tube body 40 that the height of the material accumulated in the transparent tube body is getting lower and lower. When it reaches a certain height, the speed of the material dividing component 20 can be appropriately adjusted to improve the efficiency of the leakage, so as to make the material flow smoothly. The height of the material cached in the transparent first tube body 40 no longer decreases; similarly, when the leakage speed is high, the staff can observe through the transparent first tube body 40 that the height of the material is getting higher and higher. When it reaches a certain height, the staff can choose to adjust the efficiency of the material distribution component 20; it is understandable that this solution is based on the actual premise that there are working errors. Adjustments are made, that is, in actual applications, although a quantitative feeding device can be used to achieve timed and quantitative feeding, there will still be errors and the errors will accumulate and increase over time. This solution cleverly adds a material guide component to achieve material caching, so that the staff can observe the accumulated errors in time and make timely adjustments to avoid excessive material accumulation or insufficient material supply, thereby ensuring the smooth progress of the extrusion process.

[0046] Specifically, the leakage bin 30 is funnel-shaped;

[0047] In the above solution, the leakage bin 30 is funnel-shaped, so that the leaked materials can be better concentrated at the inlet of the first tube body 40 .

[0048] For details, see Figure 2-3 The material distribution assembly 20 includes two material leakage plates 21, a turntable 22 rotatably arranged between the two material leakage plates 21, and a rotating driving member for driving the turntable 22 to rotate;

[0049] Furthermore, the leakage plate 21 is provided with a first leakage hole group, and the first leakage hole group is provided with multiple groups and is distributed at equal angles around its axis; the turntable 22 is provided with a second leakage hole group 212. When the through holes of the first leakage hole group are connected with the through holes of the second leakage hole group 212, the material is suitable for entering the leakage bin 30 from the storage bin 10;

[0050] In the above scheme, the turntable 22 is rotatably arranged between the two leakage plates 21. Only when the second leakage hole 212 group of the turntable 22 is rotated to connect with the first leakage hole group of the upper and lower leakage plates 21, the material will enter the leakage bin 30 from the storage bin 10. The rotation speed of the turntable 22 is constant, so timed intermittent leakage can be achieved during the rotation process.

[0051] For details, see Figure 4 The storage bin 10 is provided with a first material separator 11 and a second material separator 12. The first material separator 11 extends along the radial direction of the storage bin 10 and a plurality of first material separators 11 are distributed at equal angles. The second material separator 12 is annular and is divided into an inner ring area 13 and an outer ring area 14.

[0052] Furthermore, the inner ring area 13 is used for loading masterbatches; the outer ring area 14 is used for loading raw materials;

[0053] In the above scheme, this scheme utilizes the first material separator 11 and the second material separator 12 to separate the storage bin 10 into multiple areas, wherein multiple areas are formed near the inner ring area 13 under the separation action of the first material separator 11 for loading the same or different masterbatches, and multiple areas are formed in the outer ring area 14 under the separation action of the first separator for loading the same or different raw materials. In this way, the staff can fill appropriate materials in different areas according to actual needs to better adapt to the actual production situation.

[0054] Specifically, the number of the first leakage hole groups is the same as the number of the first separator plates 11;

[0055] Furthermore, the first leakage hole group includes a first through hole 211 and a second through hole, the first through hole 211 is located in the inner ring area 13, and the second through hole is located in the outer ring area 14;

[0056] Specifically, the second leakage hole group 212 includes a third through hole 221 and a fourth through hole 222. The first through hole 211 is located on the moving path of the third through hole 221, and the second through hole is located on the moving path of the fourth through hole 222.

[0057] Furthermore, the first through hole 211 and the second through hole are located on the same radial line of the leakage plate 21; the third through hole 221 and the fourth through hole 222 are not located on the same radial line of the rotating plate 22;

[0058] When the third through hole 221 is connected to the first through hole 211, the fourth through hole 222 is not connected to the second through hole.

[0059] In the above scheme, the third through hole 221 and the fourth through hole 222 on the turntable 22 are staggered. When the turntable 22 rotates, the first through hole 211 is connected to the third through hole 221, and the masterbatch passes through the first through hole 211 of the upper leakage disk 21 and then enters the third through hole 221 and then passes through the first through hole 211 of the lower leakage disk 21 into the leakage bin 30. It can be understood that at this time, the second through hole and the fourth through hole 222 are not connected, so only the masterbatch completes the unloading; similarly, as the turntable 22 rotates, the second through hole and the fourth through hole 222 are connected. At this time, the raw material is unloaded, but the masterbatch cannot be unloaded, so that the sequential unloading of masterbatch and raw material can be achieved.

[0060] Specifically, the rotary drive member includes a first gear 60 and a rotary motor suitable for driving the first gear 60 to rotate. A tooth 223 is provided on the outer periphery of the turntable 22. The first gear 60 meshes with the tooth 223 to drive the turntable 22 to rotate.

[0061] In the above solution, the rotating motor drives the first gear 60 to rotate. Teeth 223 are provided on the outer periphery of the turntable 22. The teeth 223 can be engaged with the first gear 60. Therefore, when the first gear 60 rotates, the turntable 22 can be driven to rotate.

[0062] Specifically, the first tube body 40 includes a first segment 41 close to the leakage bin 30, a second segment 42 close to the extruder 50, and a third segment 43 located between the first segment 41 and the second segment 42; the third segment 43 is detachably connected to the first segment 41 and the second segment 42 respectively;

[0063] Furthermore, the third segment 43 is provided with multiple segments and is detachably connected;

[0064] In the above solution, the first tube body 40 in this solution is detachably connected by a multi-section structure, so in actual application, the length of the first tube body 40 can be adjusted according to actual needs; at the same time, in subsequent maintenance, if part of the tube body is damaged, the damaged part can be replaced without replacing the entire tube body, effectively reducing maintenance costs.

[0065] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
