Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of consumables monitoring, in particular to a consumables monitoring component of a printer. Background Art
[0002] 3D printing, also known as additive manufacturing, is an advanced manufacturing process that uses digital technology to build objects layer by layer. The working principle of 3D printing technology is based on digital model files. Powdered metals, plastics and other bondable materials are stacked layer by layer through special 3D printers to eventually form a three-dimensional solid object.
[0003] During the 3D printing process, the material needs to be fed continuously to ensure the normal printing process. When the 3D printer is in use, the consumables are heated to a molten state and continuously accumulated to form a three-dimensional model. During this process, the consumables are extruded through the nozzle inside the printer.
[0004] Since the nozzle of a 3D printer is relatively precise, with a commonly used diameter of 0.4mm, when the consumables contain impurities or the temperature setting is inappropriate, the nozzle is easily blocked. At this time, the machine is still operating normally, but the consumables cannot be extruded normally, resulting in failure of the printing model. It is difficult for the staff to promptly learn of the abnormal delivery of the consumables, and it is inconvenient to adjust the current situation in time. Therefore, a consumables monitoring component for a printer is proposed. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a consumables monitoring component for a printer, aiming to solve the above problems.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A consumables monitoring component for a printer, comprising a printer feed port and a support platform, and further comprising:
[0008] The upper end of the support platform is fixedly connected to a support frame and a controller, the inner side of the support frame is rotatably connected to a consumable roller, the outer end of the support frame is fixedly connected to a discharging cylinder, three groups of limiting rollers and three groups of supporting rollers are arranged inside the discharging cylinder, an angular velocity sensor is installed at the outer end of the discharging cylinder, and a linear velocity sensor is installed at the outer side of the supporting roller.
[0009] Preferably, the limiting roller is located at the upper side of the inner end of the discharging cylinder, and the supporting roller is rotatably connected to the lower side of the inner end of the discharging cylinder.
[0010] Preferably, the input end of the angular velocity sensor is connected to a supporting roller thereof, and the angular velocity sensor is connected to a controller signal.
[0011] Preferably, the linear speed sensor is fixed to the lower side of the inner end of the discharge barrel through a mounting block, and the linear speed sensor is connected to the controller signal.
[0012] Preferably, the controller is located below the discharge barrel and fixedly connected to the upper end of the support platform.
[0013] Preferably, a buzzer is installed inside the controller, and the buzzer is electrically connected to the controller.
[0014] Preferably, an electric push rod is fixed to the upper end of the discharging cylinder, an output end of the electric push rod is connected to a lifting frame, and the limiting roller is rotatably connected to the inside of the lifting frame.
[0015] Preferably, limiting rods fixedly connected to the lifting frame are respectively installed on both sides of the electric push rod, and the limiting rods are slidably connected to the inner side of the discharge barrel.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] The utility model provides a consumables monitoring component for a printer. When the linear consumables are being transported, the linear speed sensor monitors the linear speed of the wire feeding. At the same time, the bottom wheel rotates driven by the consumables. In this process, the angular speed sensor monitors the angular speed of the roller rotation and transmits the two types of data to the control center for processing. The device collects data on the normal feeding speed of the consumables. When the feeding is abnormal, the feeding speed of the consumables is reduced. At this time, the control center compares the two types of data. If the data is less than the data interval of the normal feeding, the control center issues an alarm through a buzzer.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] A consumables monitoring component for a 3D printer includes a printer feed port 1 and a support table 2. By putting linear consumables into the printer feed port 1, and under the conditions of the prior art, the linear consumables entering the printer feed port 1 will be automatically collected by the 3D printer, and the consumables will be hot-melted and then ejected through the nozzle to perform 3D printing.
[0024] A support frame 3 is fixed to the upper end of the support platform 2, and a consumable roller 4 is rotatably connected to the inner side of the support frame 3. The linear consumables to be printed are bundled on the outer side of the consumable roller 4, and the consumables are supported by the consumable roller 4. A discharge cylinder 5 is fixed to the outer end of the support frame 3. After the linear consumables to be used are pulled out of the discharge cylinder 5, they are connected to the printer feed port 1. During this process, the consumable roller 4 rotates.
[0025] In this embodiment, please refer to Figure 1-3 Three groups of limiting rollers 7 are installed on the upper side of the inner end of the discharge cylinder 5, and three groups of supporting rollers 6 are rotatably connected to the lower side of the inner end of the discharge cylinder 5. The conveying of linear consumables can be limited by the limiting rollers 7 and the supporting rollers 6, so that the consumables can remain flat during conveying. An angular velocity sensor 10 is installed on the outer end of the discharge cylinder 5. The angular velocity sensor 10 is fixed to the discharge cylinder 5 with bolts, and the input end of the angular velocity sensor 10 is connected to one of the supporting rollers 6, so that the angular velocity of the supporting roller 6 during conveying can be measured by the angular velocity sensor 10 during the rotation process.
[0026] Furthermore, a linear speed sensor 9 is provided on the outer side of the support roller 6, and a mounting block 91 is fixed on the outer side of the linear speed sensor 9. The mounting block 91 is fixed on the lower side of the inner end of the discharge cylinder 5. The conveying speed of the linear consumable is detected by the linear speed sensor 9. At the same time, the linear speed sensor 9 and the angular velocity sensor 10 are connected to the controller 8 through a conveying cable for signal connection, so that the linear speed sensor 9 and the angular velocity sensor 10 can determine whether the conveying of the linear consumable is normal, and the controller 8 is located below the discharge cylinder 5 and fixed on the upper end of the support table 2.
[0027] The controller 8 has a built-in buzzer, which is electrically connected to the controller 8. When the data acquired by the controller 8 is abnormal, the buzzer is activated to sound an alarm to remind the staff.
[0028] For further examples, see Figure 1 and Figure 2 A lifting frame 71 is provided on the outer side of the limiting roller 7, and the limiting roller 7 is rotatably connected to the inside of the lifting frame 71. An electric push rod 11 is installed on the upper end of the lifting frame 71, and the electric push rod 11 is fixed to the upper end of the discharge cylinder 5, and the output end of the electric push rod 11 is connected to the lifting frame 71, so that the lifting frame 71 is controlled by the electric push rod 11 to drive the limiting roller 7 to rise and fall, and limiting rods 72 are respectively provided on both sides of the electric push rod 11, and the limiting rods 72 are slidably connected to the inner side of the discharge cylinder 5 and fixed to the lifting frame 71, so as to further improve the stability of the lifting frame 71 when rising and falling.
[0029] During use, the linear consumables are first bundled on the outside of the consumable roller 4, and one end of the consumable is pulled out of the discharge barrel 5 and connected to the printer feed port 1, and then the electric push rod 11 is started to lower the lifting frame 71 so that the limiting roller 7 and the support roller 6 are in close contact with the consumables.
[0030] When the 3D printer is in operation, the linear consumables are automatically collected by the 3D printer. Since the limit roller 7 and the support roller 6 are in close contact with the consumables, the support roller 6 is affected by the friction force to rotate. During the rotation of the support roller 6, the angular velocity sensor 10 detects the rotation speed of the support roller 6 and transmits it to the controller 8. At the same time, the linear velocity sensor 9 detects the conveying speed of the linear consumables and inputs it into the controller 8. When the nozzle of the 3D printer is blocked, the extrusion of the hot-melted consumables slows down, resulting in a decrease in the conveying speed of the consumables, thereby changing the rotation speed detected by the angular velocity sensor 10 and the conveying speed detected by the linear velocity sensor 9. After the angular velocity sensor 10 and the linear velocity sensor 9 input the data into the controller 8, the controller 8 compares the current data with the normal data and detects that the data at this time is abnormal, which is much smaller than the normal data range. The controller 8 then starts the buzzer to sound an alarm to remind the staff that the consumables feeding is abnormal at this time so that timely adjustments can be made.
