[0002] 3D printing is an advanced technology for manufacturing three-dimensional objects. Compared with traditional industrial manufacturing, it does not require molds or large production lines. Simply put, 3D printing is to build an object by stacking materials layer by layer on a machine according to a three-dimensional model generated by a computer. A 3D printing consumable testing device is a device used to detect and verify the performance of 3D printing materials. These devices can test various physical and mechanical properties of consumables, such as diameter, strength, elasticity, fluidity, etc., to ensure that they meet the printing requirements and standards.

[0003] If the diameter of the consumable is too large, it cannot be inserted into the 3D printing pen for use. Therefore, during the production process of 3D printing consumables, it is necessary to use a 3D printing consumable testing device to test the diameter of the consumables and pick out the consumables with too large diameters. The existing devices for detecting the diameter of 3D printing consumables have complex structures, cumbersome operations, and low detection efficiency. In view of the above problems, the inventor proposes a 3D printing consumable testing device to solve the above problems. Content of the Utility Model

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: As Figures 1-5As shown in the figure, the utility model provides a 3D printing consumable testing device, which includes an operation table 1. On the operation table 1, symmetrically distributed first fixing plates 2 and second fixing plates 3 are fixedly installed. Three equally spaced first sliding rods 6 are slidably inserted into the first fixing plate 2. One end of the three first sliding rods 6 is fixedly installed with a first limiting plate 4. First springs 7 are sleeved on the three first sliding rods 6. One end of one of the first sliding rods 6 is fixedly installed with a pull ring 18. Two symmetrically distributed second sliding rods 19 are slidably inserted into the second fixing plate 3. One end of the two second sliding rods 19 is fixedly installed with a second limiting plate 5, and the first limiting plate 4 and the second limiting plate 5 can be mutually attached. Second springs 8 are sleeved on the two second sliding rods 19. A limiting rod 10 is slidably installed in the second fixing plate 3. First, according to the diameter size of the qualified consumable, the position of the limiting rod 10 is slidably adjusted to limit the second limiting plate 5. Then, the first limiting plate 4 is pulled by the pull ring 18, and the first spring 7 is compressed, so that the first limiting plate 4 is separated from the second limiting plate 5. Then, the consumable is held by hand and placed between the first limiting plate 4 and the second limiting plate 5, and the pull ring 18 is released to make the first limiting plate 4 reset. The first limiting plate 4 and the second limiting plate 5 are used to clamp the consumable. The resilience of the first spring 7 is greater than the resilience of the second spring 8. While the first limiting plate 4 rebounds and resets to clamp the consumable, the second limiting plate 5 is pushed to move according to the diameter of the consumable. If the diameter of the consumable is greater than the set diameter size, the second limiting plate 5 will push the limiting rod 10 to move, so as to facilitate the detection of the diameter of the consumable and pick out the consumable with an oversize diameter.

[0021] A sliding plate 9 is slidably installed on the operation table 1. Two symmetrically distributed telescopic rods 15 are fixedly installed on one side of the sliding plate 9, and one end of the telescopic rods 15 is fixedly connected with one end of the limiting rod 10. Third springs 16 are sleeved on the two telescopic rods 15. A threaded rod 20 is rotatably installed in the operation table 1, and the threaded rod 20 is threadedly inserted into the bottom end of the sliding plate 9. One end of the threaded rod 20 is fixedly installed with a first knob 21.

[0022] By adopting the above technical solution, according to the diameter size of the qualified consumable, the first knob 21 is used to drive the threaded rod 20 to rotate, the threaded rod 20 drives the sliding plate 9 to move, and the sliding plate 9 drives the limiting rod 10 to slide and adjust the position through the telescopic rods 15 and the third springs 16, so that the limiting rod 10 limits the second limiting plate 5. The resilience of the third spring 16 is less than the resilience of the second spring 8. After the detection is completed, the first limiting plate 4 is pulled by the pull ring 18 to separate the first limiting plate 4 from the second limiting plate 5. At the same time, the resilience of the third spring 16 is used to reset the limiting rod 10 to separate it from the motor switch 17.

[0023] A motor switch 17 is fixedly installed on one side of the sliding plate 9, and one end of the limit rod 10 can contact the motor switch 17. A support plate 12 is fixedly installed on the operating table 1, and a turntable 13 is rotatably installed on the support plate 12. A collection box 14 is placed on the upper surface of the turntable 13. An opening groove 22 is opened on the operating table 1, and the collection box 14 is located below the opening groove 22. A servo motor 24 is fixedly installed on the lower surface of the support plate 12, and the output end of the servo motor 24 is fixedly connected to the center of the lower surface of the turntable 13. A connecting line 11 is fixedly installed between the servo motor 24 and the motor switch 17.

[0024] By adopting the above technical solution, the collection box 14 is divided into two collection bins, which respectively collect consumables with diameters less than or equal to the set diameter size and consumables with diameters greater than the set diameter size. The default state of the collection box 14 is that the collection bin for collecting consumables with diameters less than or equal to the set diameter size is aligned with the opening slot 22. If the diameter of the consumable is greater than the set diameter size, the second limit plate 5 will push the limit rod 10 to move, and the limit rod 10 touches the motor switch 17 to turn on (the motor switch 17 is a button switch, which is turned on by pressing and turned off by releasing. Each time the motor switch 17 is pressed, the servo motor 24 can be turned on by the connecting line 11 The motor switch 17 turns on the servo motor 24 through the connecting line 11, and the servo motor 24 drives the turntable 13 and the collection box 14 to rotate 180 degrees, so that the collection bin for collecting consumables with a diameter greater than the set diameter is aligned with the opening slot 22. After the detection is completed, the pull ring 18 is used to pull the first limit plate 4 to disengage the first limit plate 4 from the second limit plate 5. At the same time, the consumables after the detection fall into the corresponding collection bin in the collection box 14, and the motor switch 17 is manually pressed to cause the servo motor 24 to drive the turntable 13 and the collection box 14 to rotate and reset.

[0025] Two symmetrically distributed clamping plates 25 are slidably installed on the turntable 13, and the side of the two clamping plates 25 close to each other can fit with the collection box 14. A bidirectional screw rod 26 is rotatably installed in the turntable 13, and the bidirectional screw rod 26 is threadedly inserted in the two clamping plates 25, and a second knob 23 is fixedly installed on one end of the bidirectional screw rod 26.

[0026] By adopting the above technical solution, the second knob 23 is used to drive the bidirectional screw 26 to rotate, and the bidirectional screw 26 drives the two clamping plates 25 to move toward or away from each other, so as to clamp or release the collection box 14 in the center, thereby facilitating the placement and removal of the collection box 14.

[0027] Working principle: When the utility model is in use, first, according to the diameter size of the qualified consumables, the first knob 21 is used to drive the threaded rod 20 to rotate. The threaded rod 20 drives the sliding plate 9 to move. The sliding plate 9 drives the limiting rod 10 to slide and adjust the position through the telescopic rod 15 and the third spring 16, so that the limiting rod 10 limits the second limiting plate 5. Then, the first limiting plate 4 is pulled by the pull ring 18, and the first spring 7 is compressed, so that the first limiting plate 4 is separated from the second limiting plate 5. Then, the consumables are held by hand and placed between the first limiting plate 4 and the second limiting plate 5, and the pull ring 18 is released to reset the first limiting plate 4. The first limiting plate 4 and the second limiting plate 5 are used to clamp the consumables. The resilience of the first spring 7 is greater than that of the second spring 8. While the first limiting plate 4 rebounds and resets to clamp the consumables, the second limiting plate 5 is pushed to move according to the diameter of the consumables. If the diameter of the consumables is greater than the set diameter size, the second limiting plate 5 will push the limiting rod 10 to move, and the limiting rod 10 touches the motor switch 17 to turn it on. The motor switch 17 enables the servo motor 24 through the connecting wire 11. The servo motor 24 drives the turntable 13 and the collection box 14 to rotate 180 degrees, so that the collection bin for collecting consumables with a diameter greater than the set diameter size is aligned with the opening slot 22. After the detection is completed, the first limiting plate 4 is pulled by the pull ring 18, so that the first limiting plate 4 is separated from the second limiting plate 5. At the same time, the detected consumables fall into the corresponding collection bin in the collection box 14, thereby facilitating the detection of the diameter of the consumables, picking out the consumables with too large a diameter, and improving the detection efficiency.

Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model is also intended to include these changes and modifications.
