Description

TECHNICAL FIELD

[0002] Currently, the FDM (Fused Deposition Modeling) technology has various types of equipment, aiming to meet the diversified needs of different industries for the molding size. The molding size of these devices ranges widely, from 100mm of small entry-level to 1000mm of large industrial level, fully adapting to various application scenarios from personal hobbyists to professional manufacturing fields.

[0003] Especially for those scenarios that require long-time continuous printing, the amount of material consumed in a single printing can reach 20 kilograms. In this case, since the nozzle of the 3D printer has a large moving distance on the X and Y axes, the requirement for printing speed is also increased. However, as the speed increases, the inertia problem caused by the rapid movement of the nozzle becomes particularly prominent, which easily causes excessive release of consumables, and further leads to the empty running of the material tray, which may cause the phenomenon of entanglement or knotting of consumables. These problems not only affect the uniform feeding of the extruder, but also directly interfere with the normal progress of the printing task, and in severe cases, may even cause the entire printing process to fail, negatively affecting the production efficiency of the user.

[0021] The utility model can be explained in detail through the following examples, the purpose of the utility model is disclosed to protect all technical improvements within the scope of the utility model, in the description of the utility model, it is understood that if there are terms "upper", "lower", "front", "rear", "left", "right" and so on indicate the orientation or positional relationship, only with the drawing of the application, in order to facilitate the description of the utility model, and not indicate or imply that the device or element must have a particular orientation.

[0022] Example 1, in combination with the attached Figs. 1-2 A 3D printing consumable support with damping, comprising a base 1, a damping plate 2 and a damping adjusting mechanism 3; the top of the base 1 is provided with a support 5 for supporting a tray 4. The tray 4 is connected with the support 5 through a rotating shaft 6, which makes the tray 4 freely rotate on the support 5, that is, in actual operation, the tray 4 can be erected on the top of the support 5 through the rotating shaft 6, so as to realize its rotating function.

[0023] Below the tray 4, a damping plate 2 capable of producing frictional contact with the outer edge of the tray 4 is arranged. One end of the damping plate 2 is hinged with the support 5, and a damping adjusting mechanism 3 is installed on the base 1 corresponding to the position of the other end of the damping plate 2. The function of this mechanism is to adjust the frictional force between the damping plate 2 and the tray 4. Specifically, when it is necessary to increase the rotational resistance to prevent the tray 4 from releasing too much material due to inertia, even the material is wound or knotted, the damping plate 2 is pulled upward by the damping adjusting mechanism 3, so that the damping plate 2 frictionally contacts the outer circle of the tray 4, and the rotational resistance of the tray 4 is increased.

[0024] The damping adjustment mechanism 3 comprises a door-shaped frame 3-1 fixed on the base 1, and a movable stud 3-2 inserted into a through hole at the top of the door-shaped frame 3-1. The lower end of the stud 3-2 is connected to the damping plate 2 through a tension spring 3-3, and the part of the stud 3-2 above the door-shaped frame 3-1 is connected to an adjusting nut 3-4 through threads. The user can control the length of the stud 3-2 extending out of the door-shaped frame 3-1 by rotating the adjusting nut 3-4, thereby adjusting the tension of the tension spring 3-3. As the tension spring 3-3 is gradually tightened, the damping plate 2 will be raised, resulting in an increase in the friction between the damping plate 2 and the outer edge of the tray 4; conversely, if the tension spring 3-3 is loosened, the friction will decrease accordingly. This mechanism not only has a simple design, but also is very convenient to operate.

[0025] In addition, in order to improve the convenience of adjustment, the adjusting nut 3-4 is replaced by a hand-tightening nut, so that the adjustment work can be easily completed without the aid of tools.

[0026] It is worth noting that when designing, the tension provided by the tension spring 3-3 should always be less than the weight of the tray 4, so as to avoid the tray 4 being lifted off the support 5 by the damping plate 2 due to excessive tension, thereby affecting normal use.

[0027] Embodiment 2, combined with the attached Fig. 3 A 3D printing material support with damping, which is different from embodiment 1 in that on the basis of embodiment 1, the shaft body of the rotating shaft 6 is designed with a necked part corresponding to the support 5 for rotary connection, i.e. a U-shaped notch is formed at the top of the support 5, and the necked part of the rotating shaft 6 is embedded into the corresponding U-shaped notch of the support 5. Such design not only ensures that the rotating shaft 6 can rotate freely on the support 5, but also effectively limits the axial movement of the rotating shaft 6, avoiding the risk of accidental disengagement of the rotating shaft 6 from the support 5.

[0028] In order to further enhance the stability of the tray 4, threaded limiting sleeves 7 are also provided on the shaft body of the rotating shaft 6 corresponding to the two sides of the tray 4. Through the two limiting sleeves 7, the sliding of the tray 4 along the direction of the shaft body of the rotating shaft 6 can be effectively prevented. In particular, the end of the limiting sleeve 7 facing the tray 4 is designed in a conical structure, which can tightly fit with the center hole of the tray 4, ensuring that the tray 4 and the rotating shaft 6 maintain good coaxiality, thereby significantly improving the stability of the tray 4 during rotation.

[0029] The utility model discloses the part of not detailed is prior art, for the person skilled in the art, apparently the utility model is not limited to the details of the above exemplary embodiments, and can realize the utility model with other specific forms without departing from the spirit or basic characteristics of the utility model, therefore, no matter from which point, should be regarded as exemplary, and is non - limitative, aims at including all changes in the meaning and range of equivalent elements in the utility model.
