Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a manual leveling mechanism for a printing platform. Background Technology

[0002] In the 3D printing process, the flatness of the printing platform plays a crucial role in print quality. If the printing platform is not level, the printing material will not adhere evenly to the platform after extrusion, resulting in quality problems such as dimensional deviations, weak interlayer bonding, and rough surfaces in the printed object. In severe cases, it may even cause the printing job to fail.

[0003] Currently, most 3D printers on the market are equipped with manual leveling mechanisms, but these mechanisms often have some drawbacks. On the one hand, some traditional leveling mechanisms have four to five adjustment points, making leveling operations cumbersome and requiring numerous adjustments, consuming a significant amount of user time and effort and reducing the printing efficiency of the 3D printer. On the other hand, many leveling mechanisms lack clear leveling reference points, making it difficult for users to accurately determine the horizontal state of the printing platform during the leveling process. This leads to inconsistent leveling operations between different levels, affecting the stability of print quality.

[0004] Therefore, in order to improve the quality and efficiency of 3D printing, designing a manual leveling mechanism for the printing platform that is simple in structure, easy to level, and can ensure leveling consistency has become an urgent problem to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a manual leveling mechanism for a printing platform.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A manual leveling mechanism for a printing platform, comprising:

[0008] Printing platform;

[0009] The leveling base, located at the bottom of the printing platform, is used to support the printing platform;

[0010] There are three Z-axis adjusting bolts, which pass through the printing platform and are threaded to the three corner ends of the leveling base respectively; there are countersunk holes at the bottom of the printing platform corresponding to the Z-axis adjusting bolts.

[0011] There are three support springs, which are installed in three countersunk holes at the bottom of the printing platform.

[0012] The support boss is located at one corner of the leveling base where the Z-axis adjustment bolt is not installed. Its top contacts the printing platform and serves as a leveling reference point.

[0013] Preferably, connectors are installed at the four corners of the leveling base at the bottom of the printing platform; three connectors corresponding to the three Z-axis adjusting bolts are provided with strip slots, and the other connector is provided with a through hole. X-axis locking bolts that are threadedly connected to the leveling base are installed at the strip slots or through holes of the connectors.

[0014] Preferably, the threaded hole at the Z-axis adjusting bolt on the leveling base is a through hole, and both ends of the Z-axis adjusting bolt are provided with tightening grooves.

[0015] Preferably, the tightening groove at the bottom of the Z-axis adjusting bolt is an internal hexagonal groove.

[0016] Preferably, the Z-axis adjusting bolt is a flat-head screw.

[0017] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0018] (1) The leveling efficiency of this utility model is greatly improved. The leveling base has three Z-axis adjusting bolts and a support boss. With the support boss as the leveling reference point, leveling can be achieved by adjusting only the three Z-axis adjusting bolts. Compared with the traditional structure with multiple adjustment points and no reference, it reduces the number of adjustments, saves manual leveling time, improves leveling efficiency, and makes it easier for users to quickly complete the leveling operation.

[0019] (2) The leveling reference point of this utility model is preset at the factory, which ensures the consistency between multiple leveling operations. This allows the printing platform to maintain a relatively stable and uniform level when leveling operations are performed at different times and in different environments, which is conducive to improving the stability of printing quality and avoiding printing errors caused by inconsistent leveling.

[0020] (3) The threaded hole corresponding to the Z-direction adjusting bolt position on the leveling base of this utility model is a through hole, and the Z-direction adjusting bolt has tightening grooves at both ends. The operator can adjust it from the printing platform side or the bottom of the leveling base, providing multiple operation options and improving the flexibility and convenience of the adjustment operation. In particular, the internal hexagonal groove design at the bottom end allows the operator to adjust it from the bottom of the leveling base with the help of an internal hexagonal wrench, making the leveling operation more convenient.

[0021] (4) The Z-axis adjusting bolt of this utility model is a flat-head screw, the head of which can be hidden inside the printing platform. At the same time, it effectively limits the horizontal movement of the printing platform, preventing excessive displacement of the platform in the horizontal direction, ensuring stability during the printing process, and improving printing accuracy. In addition, support springs are installed in the countersunk holes at the bottom of the printing platform corresponding to the three Z-axis adjusting bolts. When adjusting the Z-axis adjusting bolts, the support springs can raise or lower the platform, providing support and elastic adjustment for the platform, further improving the stability and adaptability of the structure.

[0022] (5) Before the printing platform is leveled, the four X-direction locking bolts can be loosened for leveling. After leveling, the four X-direction locking bolts can be tightened to reliably lock the printing platform, ensuring that the printing platform has the corresponding load-bearing capacity, so that it can stably bear the printing material and printing parts during the printing process, meet the needs of 3D printing, and improve the reliability and safety of printing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] Example 1:

[0034] Combined with appendix Figures 1-6 A manual leveling mechanism for a printing platform includes a printing platform 1, a leveling base 2, a Z-axis adjusting bolt 3, and a support spring 4. Specifically, the leveling base 2 is located at the bottom of the printing platform 1, and its main function is to support the printing platform 1. In practical applications, the leveling base 2 needs to be installed on the power guide rail of the 3D printer to drive the printing platform 1 to move along the Y-axis.

[0035] There are three Z-axis adjusting bolts 3, which pass through the printing platform 1 and are threaded to the three corner ends of the leveling base 2. At the bottom of the printing platform 1, countersunk holes are provided corresponding to the positions of the Z-axis adjusting bolts 3, and support springs 4 are installed in each of these countersunk holes, as shown in the attached diagram. Figure 4 As shown. When the Z-axis adjusting bolt 3 is loosened, the corresponding support spring 4 will cause the printing platform 1 to rise; conversely, if the Z-axis adjusting bolt 3 is tightened, the printing platform 1 will fall, thereby compressing the support spring 4.

[0036] The corner end of the leveling base 2 that is not fitted with the Z-axis adjusting bolt 3 is provided with a support boss 5, as shown in the attached figure. Figure 5As shown, the top of the support boss 5 contacts the corresponding position of the printing platform 1, serving as a reference point during the leveling process. When adjusting the level of the printing platform 1, the support boss 5 is used as the leveling reference point, and this is achieved by adjusting the three Z-axis adjusting bolts 3. Compared to traditional structures with four to five adjustment points and lacking a leveling reference, the structure presented in this embodiment significantly reduces the number of adjustments, thereby saving time required for manual leveling. Furthermore, the leveling reference point is pre-set at the factory, ensuring consistency between multiple leveling operations.

[0037] Example 2:

[0038] See attached document Figure 3 To be continued Figure 5 The manual leveling mechanism for the printing platform shown differs from that in Embodiment 1. Specifically, connectors 6 are installed at the bottom of the printing platform 1, corresponding to the four corners of the leveling base 2. The three connectors 6 corresponding to the three Z-axis adjusting bolts 3 have strip-shaped slots, as shown in the attached diagram. Figure 4 As shown, the other connector 6 is provided with a through hole, as shown in the attached figure. Figure 5 As shown. At the slotted or through-hole position of the connector 6, an X-direction locking bolt 7 is fitted, corresponding to the leveling base 2 and threadedly connected. The slotted design on the connector 6 is primarily to allow for vertical adjustment margins for the printing platform 1 during leveling. At the leveling reference point, the through-hole on the connector 6 is for installing the corresponding X-direction locking bolt 7. Since this point is a leveling reference point, no vertical movement is required during leveling, therefore, there is no need to reserve vertical adjustment margins.

[0039] It is important to emphasize that before leveling the printing platform 1, the four X-direction locking bolts 7 must be loosened first. After the leveling work is completed, these four X-direction locking bolts 7 should be tightened to lock the printing platform 1 and ensure that the printing platform 1 has the corresponding load-bearing capacity.

[0040] Example 3:

[0041] Combined with appendix Figure 4 As can be seen, this manual leveling mechanism for the printing platform is an improvement upon either Embodiment 1 or Embodiment 2. The threaded hole corresponding to the Z-direction adjusting bolt 3 on the leveling base 2 is designed as a through hole, and both ends of the Z-direction adjusting bolt 3 are provided with tightening grooves. In this way, the operator can adjust the Z-direction adjusting bolt 3 from either the printing platform 1 side or from the bottom of the leveling base 2, greatly improving the flexibility and convenience of the adjustment operation.

[0042] Furthermore, the tightening groove at the bottom of the Z-axis adjusting bolt 3 is designed as an internal hexagonal socket, which allows the operator to adjust the Z-axis adjusting bolt 3 from the bottom of the leveling base 2 using an internal hexagonal wrench, making the leveling operation more convenient. In addition, the Z-axis adjusting bolt 3 is made of a flat-head screw, which not only allows the head of the Z-axis adjusting bolt 3 to be easily hidden inside the printing platform 1, but also effectively limits the horizontal movement of the printing platform 1.

[0043] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
