Description

Technical Field

[0001] The utility model relates to a mechanical structure, more specifically, to a printing platform connection structure of a printer. Background Art

[0002] There is a printing platform inside the printer, which supports the paper during printing. The printing platform needs to be preheated during printing so that the printed ink can dry quickly, the printing point will be accurate, and the final printing quality will be improved. However, in actual use, it is found that the printing platform in the existing technology is usually made of aluminum, which will deform when heated. The hard connection method causes the printing platform to drive the frame to deform when heated, thus creating a vicious cycle and causing the platform deformation to increase significantly. Therefore, a printer printing platform connection structure is needed. This structure uses a soft connection method, which can reduce the deformation of the printing platform due to heat and improve the printing quality.

[0003] Considering the above reasons, how to use a soft connection method to reduce the deformation amplitude of the printing platform due to heat is exactly the issue considered in this application. Utility Model Content

[0004] In response to the shortcomings of the existing technology, a printer printing platform connection structure is provided. The structure adopts a soft connection method, which can reduce the deformation of the printing platform due to heat and improve the printing quality.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: a printer printing platform connection structure, comprising a frame, a support assembly, a soft connection assembly and a platform assembly, wherein the support assembly is mounted on the frame, and two ends of the soft connection assembly are respectively connected to the support assembly and the platform assembly;

[0006] When the platform assembly expands due to heat, the platform assembly moves toward the support assembly and the flexible connection assembly deforms.

[0007] In summary, the above technical solution has the following beneficial effects: the printing platform material is usually made of aluminum alloy, which will physically expand due to the thermal expansion coefficient when heated. In addition, the printing platform is usually heated by hot air, resulting in uneven heating of the actual printing platform. Different parts expand unevenly, which will cause slight deformation. This slight deformation is acceptable. However, in the prior art, because the printing platform is rigidly constrained by screws or other fixing methods, that is, a hard connection method, its expansion is restricted when heated, which will generate internal stress, resulting in a deeper degree of deformation. The deeper degree of deformation will lead to increased internal stress, which ultimately leads to warping or distortion.

[0008] The soft connection method is a flexible fixed connection. It introduces elastic components to allow the platform to expand or contract freely when heated, thereby avoiding stress accumulation and deformation caused by rigid constraints. When the printing platform expands due to heat, the soft connection component will absorb or compensate for the thermal expansion displacement of the printing platform material through its own elastic deformation. That is, when the printing platform is heated, it moves slightly toward the support component, causing the soft connection component to deform, avoiding stress concentration caused by rigid fixation. At the same time, it reduces the mechanical constraints between the printing platform and the support component, and the deformation amplitude is greatly reduced.

[0009] In addition, the flexible connection method allows the print platform to locally fine-tune its position when heating is uneven. For example, when the center area expands, the elastic fixings at the edge can adaptively adjust to reduce overall warping caused by temperature differences. By releasing thermal stress, the warping and distortion of the print platform when heated are greatly reduced. This is particularly suitable for large-scale or high-precision printing scenarios. It also avoids metal fatigue or material cracking caused by long-term thermal stress. It allows the print platform to stretch naturally, reducing local temperature differences caused by stress at fixed points, and indirectly improving heating uniformity.

[0010] The utility model reduces the deformation of the printing platform from the perspective of reducing stress accumulation by providing a soft connection component instead of a hard connection, and the printing quality is also significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0021] Reference Figure 1-4 As shown, the printer printing platform connection structure includes a frame 1, a support component 2, a flexible connection component 3 and a platform component 4. The support component 2 is installed on the frame 1, and the two ends of the flexible connection component 3 are respectively connected to the support component 2 and the platform component 4;

[0022] When the platform assembly 4 expands due to heat, the platform assembly 4 moves toward the support assembly 2 and the flexible connection assembly 3 is deformed.

[0023] The print platform is typically made of aluminum alloy, which physically expands when heated due to its thermal expansion coefficient. Furthermore, the print platform is typically heated using hot air, resulting in uneven heating of the print platform and uneven expansion of different parts, which can lead to slight deformation. While this slight deformation is acceptable, in existing technologies, the print platform is rigidly constrained by screws or other fixing methods, i.e., a hard connection. This restricts expansion when heated, generating internal stress that increases the degree of deformation. This increased deformation in turn increases the internal stress, ultimately leading to warping or distortion.

[0024] The soft connection method is a flexible fixed connection. It introduces elastic components to allow the platform to expand or contract freely when heated, thereby avoiding stress accumulation and deformation caused by rigid constraints. When the printing platform expands due to heat, the soft connection component 3 will absorb or compensate for the thermal expansion displacement of the printing platform material through its own elastic deformation. That is, the printing platform moves slightly toward the support component 2 when heated, causing the soft connection component 3 to deform, avoiding stress concentration caused by rigid fixation. At the same time, it reduces the mechanical constraints between the printing platform and the support component 2, and the deformation amplitude is greatly reduced.

[0025] In addition, the flexible connection method allows the print platform to locally fine-tune its position when heating is uneven. For example, when the center area expands, the elastic fixings at the edge can adaptively adjust to reduce overall warping caused by temperature differences. By releasing thermal stress, the warping and distortion of the print platform when heated are greatly reduced. This is particularly suitable for large-scale or high-precision printing scenarios. It also avoids metal fatigue or material cracking caused by long-term thermal stress. It allows the print platform to stretch naturally, reducing local temperature differences caused by stress at fixed points, and indirectly improving heating uniformity.

[0026] The present invention provides a soft connection component 3 instead of a hard connection, thereby reducing the deformation degree of the printing platform from the perspective of reducing stress accumulation, and the printing quality is also significantly improved.

[0027] Furthermore, the soft connection component 3 includes a spring 31 , and two ends of the spring 31 are respectively in contact with the support component 2 and the platform component 4 .

[0028] Furthermore, the soft connection assembly 3 also includes a bolt 32 and a nut 33, the support assembly 2 includes a lower support member 21, the platform assembly 4 includes an upper support member 41, the lower support member 21 is provided with a lower through hole 22, and the upper support member 41 is provided with an upper through hole 42. The bolt 32 passes through the lower through hole 22 and the upper through hole 42, the head of the bolt 32 abuts against the upper support member 41, the nut 33 is threadedly connected to the bolt 32, the nut 33 abuts against the lower support member 21, and the two ends of the spring 31 abut against the lower support member 21 and the upper support member 41 respectively.

[0029] The bolt 32 and the nut 33 are mainly used as the maximum spacing limiter between the lower support member 21 and the upper support member 41. The head of the bolt 32 is arranged on the side of the upper support member 41 away from the lower support member 21, and the nut 33 is arranged on the side of the lower support member 21 away from the upper support member 41, so that the head of the bolt 32 and the nut 33 form a clamping structure to prevent the lower support member 21 and the upper support member 41 from being excessively separated. At the same time, since the position of the lower support member 21 is fixed, the upper support member 41 can be limited to move in the vertical direction along the bolt 32 when it moves due to thermal expansion, thereby preventing the upper support member 41 from causing the entire platform assembly 4 to tilt and affecting the printing quality.

[0030] Furthermore, the spring 31 is sleeved on the bolt 32 .

[0031] Furthermore, the support assembly 2 further includes a lower buffer plate 23 , which is fixedly connected to the lower support member 21 . The lower buffer plate 23 is provided with a receiving hole 24 , and the spring 31 abuts against the inner wall of the receiving hole 24 .

[0032] Furthermore, the platform assembly 4 further includes an upper buffer plate 43 , and the spring 31 abuts against the upper buffer plate 43 .

[0033] Since the spring 31 is the main medium of the soft connection, the compression and extension of the spring 31 also need to be maintained in the vertical direction, so the spring 31 is sleeved on the bolt 32, which can also prevent the spring 31 from being compressed and extended laterally and causing it to be unable to be used normally. At the same time, since the position of the lower support member 21 is fixed, a receiving hole 24 is provided on the lower buffer plate 23 to limit the movement of the spring 31. In addition, the spring 31 is a consumable component, and the contact surface with the spring 31 is also easily damaged due to friction. Therefore, the spring 31, the upper buffer plate 43 and the lower buffer plate 23 are all separated to facilitate subsequent replacement and maintenance.

[0034] Furthermore, the platform assembly 4 also includes a printing support member 44 . The printing support member 44 is provided with a plurality of vent holes 45 . The printing support member 44 is fixedly connected to the upper support member 41 .

[0035] Since the printing paper needs to be sucked by negative pressure during printing to prevent the printing paper from shifting during the printing operation, a vent hole 45 needs to be provided on the printing support member 44 used to support the printing paper so that the negative pressure operation can operate normally.

[0036] Furthermore, the upper buffer sheet 43 , the printing support member 44 and the upper support member 41 form a protection space, and the head of the bolt 32 is disposed in the protection space.

[0037] Furthermore, a mounting hole 46 is provided on the printing support 44 . The mounting hole 46 is provided above the upper through hole 42 , and the inner diameter of the mounting hole 46 is larger than the outer diameter of the bolt 32 .

[0038] In order to prevent the bolt 32 from loosening due to accidental impact or other reasons during the printing process, a protective space is provided to protect the head of the bolt 32. At the same time, for the convenience of installation, a mounting hole 46 is provided on the printing support 44 so that the bolt 32 and the screwdriver can directly pass through the mounting hole 46.

[0039] Furthermore, a plurality of cover plates 11 are provided on the frame 1 , and the cover plates 11 are used to protect the support assembly 2 , the soft connection assembly 3 and the platform assembly 4 .

[0040] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
