Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing technology, and specifically to a detection device for the print head of a 3D printing equipment. Background Technology
[0002] 3D printing, also known as three-dimensional printing or additive manufacturing technology, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional CAD data.
[0003] Currently, the print head of 3D printing equipment is used to eject printing material. During subsequent use, as the number of uses increases, the melting and cooling of the printing material causes printing material to gradually adhere and accumulate inside the print head. If the excessive accumulation of printing material inside the print head is not detected in time, it can easily affect the uniformity of subsequent printing material ejection.
[0004] To address the aforementioned issues, this application proposes a detection device for the print head of a 3D printing equipment. Utility Model Content
[0005] This utility model addresses the technical problems existing in the prior art by providing a detection device for the printing nozzle of a 3D printing equipment.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a detection device for the printing nozzle of a 3D printing equipment, including a mounting shell, wherein a detection component is movably inserted into the mounting shell;
[0007] The testing component includes a plate, and colored cotton is installed on the inner side of the plate;
[0008] The detection component is movably inserted into the mounting housing;
[0009] The mounting housing is provided with a fixing component, which is used to compress and fix the test piece.
[0010] The fixing component includes a mounting groove formed in the top wall of the mounting housing. A fixing rod is mounted on the mounting housing through the mounting groove. A rotating plate is rotatably connected to the fixing rod. A spring is mounted on the mounting housing through the mounting groove. The bottom end of the spring is connected to the top of the rotating plate. By setting the fixing component, it is convenient to fix the test piece and convenient to remove the test piece.
[0011] A grip block is provided directly below the mounting shell, and a support rod is installed on the top of the grip block. The mounting shell is installed on the top of the support rod. By providing the grip block and the support rod, it is easy to hold the entire device in one's hand.
[0012] A hemispherical groove is provided at the center of the grip block, and a switch is installed at the center of the hemispherical groove on the grip block. A flashing light is installed on the grip block and is electrically connected to the switch. A ball bearing is placed in the hemispherical groove. By setting up the hemispherical groove, switch, flashing light and ball bearing, it is easy to keep the detection piece as level as possible.
[0013] The outer side of the hand grip is equipped with an anti-slip sleeve, which increases the friction between the hand and the device.
[0014] The hand grip block is fitted with a limit strip through a hemispherical groove. By setting the limit strip, the ball bearings are prevented from detaching from the hemispherical groove as much as possible.
[0015] The beneficial effects of this utility model are:
[0016] By setting up a detection device, inserting the detection device into the mounting shell, and then moving the colored cotton directly below the print head, maintaining a certain distance so that the printing material can be colored onto the colored cotton when it is sprayed out, you can directly observe whether the printing material on the colored cotton is uniform, thereby effectively judging whether the printing material inside the print head is seriously accumulated, and thus timely discovering the internal condition of the print head, and minimizing the unevenness of subsequent printing material spraying.
[0017] After moving the colored cotton directly below the print head, if the flashing light goes out, slightly adjust the hand grip to press the ball back onto the switch, causing the switch to turn on the flashing light. This ensures that the entire device is perpendicular to the print head's ejection end, helping to ensure the accuracy of the detection. Attached Figure Description

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0031] Reference Figure 1 and Figure 2A detection device for a 3D printing nozzle includes a mounting shell 1, with a detection component 2 movably inserted inside the mounting shell 1. The detection component 2 includes an insert plate 201, and a colored cotton 202 is installed on the inner side of the insert plate 201. The detection component 2 is movably inserted into the mounting shell 1. The color of the colored cotton 202 needs to be different from the color of the printing material. Specifically, by inserting the detection component 2 into the mounting shell 1 and keeping the printing nozzle vertically downward, the colored cotton 202 is moved directly below the printing nozzle, maintaining a certain distance so that the printing material can be colored onto the colored cotton 202 when it is ejected. At this time, it is possible to directly observe whether the printing material on the colored cotton 202 is uniform, thereby effectively judging whether the printing material inside the printing nozzle is seriously accumulated, and thus timely detecting the internal state of the printing nozzle, minimizing the unevenness of subsequent printing material ejection.
[0032] Reference Figure 2 and Figure 3 The mounting housing 1 is equipped with a fixing component 3, which is used to press and fix the test piece 2. The fixing component 3 includes a mounting groove 301 opened in the top wall of the mounting housing 1. The mounting housing 1 is equipped with a fixing rod 302 through the mounting groove 301. A rotating plate 303 is rotatably connected to the fixing rod 302. The mounting housing 1 is equipped with a spring 304 through the mounting groove 301. The bottom end of the spring 304 is connected to the top of the rotating plate 303. When the test piece 2 is inserted into the mounting housing 1, the insertion plate 201 presses the rotating plate 303 to make it retract into the mounting groove 301, thereby fixing the test piece 2 in the mounting housing 1 with the help of the elastic force of the spring 304. Similarly, it is easy to pull out the test piece 2.
[0033] Reference Figure 4 and Figure 5 A handle 4 is located directly below the mounting housing 1, and a support rod 5 is mounted on the top of the handle 4. The mounting housing 1 is mounted on the top of the support rod 5. A hemispherical groove 6 is formed in the center of the handle 4, and a switch 7 is installed in the center of the hemispherical groove 6. A flashing light 9 is installed on the handle 4, and the flashing light 9 is electrically connected to the switch 7. A ball bearing 8 is placed in the hemispherical groove 6. According to the above technical solution, specifically, by holding the handle 4 and moving the colored cotton 202 directly below the print head, if the flashing light 9 goes out, the hand slightly adjusts the handle 4 so that the ball bearing 8 presses back onto the switch 7, causing the switch 7 to control the flashing light 9 to light up. This makes the entire device perpendicular to the nozzle outlet, which helps to ensure the accuracy of the detection.
[0034] Reference Figure 2 An anti-slip sleeve 10 is installed on the outside of the grip block 4 to increase the friction between the hand and the grip block 4.
[0035] Reference Figure 4The hand-held block 4 is fitted with a limit bar 11 through the hemispherical groove 6 to prevent the ball 8 from dislodging from the hemispherical groove 6 as much as possible.
[0036] Working principle:
[0037] The 3D printing equipment's nozzle detection device works by holding the grip block 4 and moving the colored cotton 202 directly below the nozzle. If the flashing light 9 goes out, the hand slightly adjusts the grip block 4 so that the ball bearing 8 presses back onto the switch 7, causing the switch 7 to control the flashing light 9 to light up. This ensures that the entire device is perpendicular to the nozzle's ejection end, helping to ensure the accuracy of the detection.
[0038] The detection device for the printhead of this 3D printing equipment inserts the detection component 2 into the mounting shell 1 while keeping the printhead vertically downward. At this time, the colored cotton 202 is moved directly below the printhead, maintaining a certain distance so that the printing material can be colored onto the colored cotton 202 when it is ejected. Then, it is possible to directly observe whether the printing material on the colored cotton 202 is uniform, thereby effectively judging whether the printing material inside the printhead is seriously accumulated, and thus promptly discovering the internal state of the printhead, minimizing the unevenness of subsequent printing material ejection.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
