Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a 3D printer with a consumable material discharge fault diagnosis and repair function and a use method thereof. Background Art

[0002] A 3D printer, also known as a three-dimensional printer, is a rapid prototyping process equipment that can convert computer-generated design files into real products. A 3D printer is a device controlled by a high-speed computer. It uses printing materials (such as plastic, metal, ceramic, etc.) to stack layer by layer according to a preset digital model to ultimately construct a three-dimensional object.

[0003] When using an existing 3D printer, the consumables need to be transferred to the heated print head, and then the print head heats the printing consumables, the consumables in the print head melt, and then the melted consumables are squeezed downward through the feeding mechanism to squeeze out the melted consumables from the print nozzle for printing. However, when the consumables are being transported and discharged, the printer's feeding control system may have discharge failures due to circuit or aging problems, resulting in the consumables being discharged too quickly. When the problem of too fast discharge speed occurs, the staff may be unable to discover it in time due to operating other equipment or paying attention to other matters, and cannot make timely diagnosis and repairs, causing the faulty printer to continue to work, resulting in loose adhesion between printing layers, interlayer peeling, misalignment and other problems, thereby affecting the overall quality and accuracy of the print.

[0016] Compared with the prior art, the present invention provides a 3D printer with consumable material discharge fault diagnosis and repair function and a method of use, which has the following beneficial effects: 1.

[0017] 2. Through the setting of the cleaning protection mechanism, the reciprocating rotation and sweeping of the conical cover and the annular brush on its top, and the impact of the airflow ejected from the air jet pipe, the dust or protruding impurities on the outer surface of the consumable body can be cleaned to prevent impurities from entering the print head body together with the consumable body, and avoid the accumulation of dust and impurities in the print head body. This can not only reduce the doping of impurities in the printed parts and improve product quality, but also reduce the accumulation of impurities in the print head body, thereby increasing the service life of the print head body. Moreover, through the setting of the conical structure of the conical cover, the dust and impurities can slide along the conical inclined surface of the conical cover after being blown away, and diffuse outward, thereby avoiding falling into the outer surface of the consumable body for the second time, thereby improving the cleaning effect. Moreover, through the blown airflow, the outer surface of the consumable body can be prevented from being wet.

[0018] 3. By rotating the contact friction upward, the speed of the consumable body feeding downward is slowed down, so that the staff can properly control the speed of the consumable body discharging before rushing over, so that the discharging speed is reduced to a certain extent, further improving the safety of the printer body when using it and ensuring the quality of the printed product.

[0027] In the prior art, the feed control system of the printer may have a discharge failure due to circuit or aging problems, resulting in the consumables being discharged too quickly. When the problem of too fast discharge speed occurs, the staff may be unable to discover it in time due to operating other equipment or paying attention to other matters, and cannot make timely diagnosis and repairs, causing the faulty printer to continue to work, resulting in loose adhesion between the printed layers, interlayer peeling, misalignment and other problems, thereby affecting the overall quality and accuracy of the print.

[0028] For further examples, please refer to Figures 1 to 8 As shown: The cleaning and protection mechanism includes a rotating disk 401, which is rotatably connected to one side of the second mounting plate 302, one end of the rotating disk 401 passes through the second mounting plate 302 and is fixedly connected to one end of the driving wheel 304, an eccentric block 402 is fixedly connected to the outer surface of the rotating disk 401, a spring rod 403 is fixedly connected to one side of the first mounting plate 301, one end of the spring rod 403 is fixedly connected to a push rod 404, the push rod 404 is slidably connected to the first mounting plate 301, a connecting rod 405 is fixedly connected to one side of the push rod 404, a linkage sleeve 406 is fixedly connected to the side of the connecting rod 405 away from the push rod 404, and a support ring 407 is fixedly connected to one side of the first mounting plate 301.

[0029] The implementation of this embodiment can not only reduce the doping of impurities in the printed parts and improve product quality, but also reduce the accumulation of impurities in the print head body 11, thereby increasing the service life of the print head body 11. Moreover, through the setting of the conical structure of the conical cover 408, dust impurities can slide along the conical inclined surface of the conical cover 408 after being blown away, and diffuse outward, thereby avoiding falling onto the outer surface of the consumable body 21 for the second time, thereby improving the cleaning effect. Moreover, the blown airflow can prevent the outer surface of the consumable body 21 from becoming wet.

[0030] Embodiment 2: Method for using a 3D printer with consumable material discharge fault diagnosis and repair function: Step 1: Preparation and settings before printing; Step 2: Printing process and material output inspection; Step 1 includes: ensuring that the power cord of the printer body 1 is stably connected to prevent power failure during printing, checking whether the printing platform is level and stable to prevent displacement and tilting during printing, fixing the consumable body 21 required for printing to the side of the consumable roller 2, inputting data parameters corresponding to the appearance of the print according to the consumable body 21, and setting the temperature of the print head body 11 to 210°C; Step two includes: passing the consumable body 21 in step one through the detection protection mechanism and the cleaning protection mechanism, and then inserting it into the print head body 11, starting the printer body 1 and printing out the required printer shape. During the printing process, if there is no alarm sound, normal printing is performed. If an alarm sound is emitted by the alarm 316, the staff must immediately stop printing and inspect and repair the printer body 1.

[0031] Everything in the above example works like this: In the initial state: the consumable body 21 is inserted into the top feed port of the print head body 11, the connecting spring 312 is in a normal state, the sliding block 313 is located in the groove of the centrifugal wheel 307, and the airbag 411 is in a normal state.

[0032] The following is the working process of the detection and protection mechanism: When in use, the consumable body 21 passes between the limiting wheel 303 and the driving wheel 304. Due to the friction between the limiting wheel 303, the driving wheel 304 and the consumable body 21, when the consumable body 21 is fed into the print head body 11, the consumable body 21 moves downward to drive the limiting wheel 303 and the driving wheel 304 to rotate. When the driving wheel 304 rotates, it drives the first gear 305 to rotate. Since the first gear 305 and the second gear 306 are in a meshing state, the second gear 306 is driven to rotate at the same time. When the consumable body 21 is feeding at a normal speed, the speeds of the first gear 305, the second gear 306 and the centrifugal wheel 307 are normal. Therefore, the centrifugal force on the sliding block 313 is normal. When the sliding block 313 rotates to the bottom, the connecting spring 312 will only produce a slight stretch. Therefore, the electrical contact 314 and the magnetic strip 315 will not contact the electrical contact ring 310 and the magnetic ring 311. When the control system of the printer body 1 fails and the discharge speed of the consumable body 21 decreases too quickly, the friction force will drive the driving wheel 304 and the first gear 305 to speed up, thereby accelerating the rotation speed of the centrifugal wheel 307, increasing the centrifugal force on the sliding block 313, causing the electric contact 314 to approach the electric contact ring 310 and contact each other, the magnetic strip 315 to approach the magnetic ring 311 and adsorb each other, and the connecting spring 312 to stretch and become larger. The electric contact 314 and the electric contact ring 310 are electrically connected to control the opening and closing of the alarm 316. At this time, the alarm 316 is turned on and an alarm sound is issued. At this time, after hearing the alarm sound, the staff can promptly discover the fault and conduct inspection and repair.

[0033] At the same time, when the discharge speed of the consumable body 21 decreases too fast, under the action of the first gear 305 and the third gear 317, the centrifugal disk 318 will be driven to rotate faster, thereby increasing the centrifugal force on the friction block 320. The increased centrifugal force increases the distance the friction block 320 slides out, and the stretching distance of the tension spring 319 increases, thereby causing the friction block 320 to slide until it contacts the consumable body 21. Since the consumable body 21 is output downward, the third gear 317 and the centrifugal disk 318 are driven to rotate in the opposite direction to the driving wheel 304 and the first gear 305. Therefore, the friction block 320 rotates upward and contacts the outer surface of the consumable body 21. The upward rotation contact friction slows down the speed at which the consumable body 21 feeds downward, so that the staff can properly control the discharge speed of the consumable body 21 before arriving, so that the discharge speed is reduced to a certain extent, further improving the safety of the printer body 1 when in use and ensuring the quality of the printed product.

[0034] By setting up the detection protection mechanism, the friction force generated by the movement of the consumable body 21 when discharging the material is used to drive the driving wheel 304, the first gear 305 and the second gear 306 to rotate, so that the centrifugal force generated by the rotation is used to make the electric contact 314 and the electric contact ring 310 contact and sound an alarm, thereby reminding the staff to arrive in time and conduct inspection and repair, avoiding the situation where the staff cannot discover the problem in time due to operating other equipment or paying attention to other matters, ensuring the safety of the printer body 1 when in use, and improving the overall quality of the printout. Compared with the prior art, the friction force generated by the movement of the consumable body 21 is used as the power, and the magnitude of the centrifugal force is used to trigger the alarm, which not only saves the installation of an additional driving source, but also does not require the maintenance of power resources during the detection process, saving the detection cost.

[0035] It should be noted that, since the diameter of the first gear 305 is larger than that of the second gear 306, when the first gear 305 rotates one circle, the second gear 306 will rotate more than one circle. At this time, the rotation speed of the second gear 306 will be faster than that of the first gear 305, thereby ensuring the stability of the centrifugal force generated when the second gear 306 and the centrifugal wheel 307 rotate.

[0036] Please refer to the above working process Figures 1 to 8 .

[0037] The following is the working process of cleaning protection mechanism: When in use, when the consumable body 21 enters the print head body 11 for discharging, the consumable body 21 moves downward to drive the driving wheel 304 to rotate. When the driving wheel 304 rotates, it will also drive the rotating disk 401 to rotate. Because the eccentric block 402 is eccentrically arranged, the rotation of the rotating disk 401 drives the eccentric block 402 to approach the push rod 404, and pushes the push rod 404 to move in the opposite direction of the airbag 411. The spring rod 403 stretches. When the eccentric block 402 is away from the push rod 404, the spring rod 403 rebounds and resets the push rod 404. Therefore, under the rotation of the rotating disk 401 and the eccentric block 402, the push rod 404 can be moved along the first One side of the mounting plate 301 slides back and forth, thereby driving the connecting rod 405 and the linkage sleeve 406 to slide back and forth. The connecting column 410 slides in the linkage sleeve 406 under the thrust, thereby pushing the connecting column 410 and the conical cover 408 to rotate back and forth, so that the annular brush on the top of the conical cover 408 sweeps the outer surface of the consumable body 21. At the same time, the push rod 404 slides back and forth, which can make the airbag 411 continuously compressed and rebound to reset. With the cooperation of the one-way air outlet valve and the one-way air inlet valve on the top of the airbag 411, the outside air continuously enters the airbag 411 and then enters the conical cover 408 from the connecting hose 412, and finally sprays out from the top of the jet pipe 409.

[0038] By setting up the cleaning protection mechanism, through the reciprocating rotation and sweeping of the conical cover 408 and the annular brush on its top, and the impact of the airflow ejected from the air jet pipe 409, the dust or protruding impurities on the outer surface of the consumable body 21 can be cleaned to prevent impurities from entering the print head body 11 together with the consumable body 21, and avoid the problem of accumulation of dust and impurities in the print head body 11. This can not only reduce the doping of impurities in the printed parts and improve product quality, but also reduce the accumulation of impurities in the print head body 11, thereby increasing the service life of the print head body 11. Moreover, through the setting of the conical structure of the conical cover 408, the dust and impurities can slide along the conical inclined surface of the conical cover 408 after being blown away, and diffuse outward, thereby avoiding falling into the outer surface of the consumable body 21 for the second time, thereby improving the cleaning effect. Moreover, through the blown airflow, the outer surface of the consumable body 21 can be prevented from becoming wet.
