[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] It should be noted that in current printing technology, in order to achieve the needs of curved surface printing, it is often necessary to use a specific mechanical structure, such as a rotating shaft, to fix and drive the product to be printed to rotate. This method does bring convenience and efficiency to curved surface printing, making the printing of various curved surface objects relatively simple.

[0040] However, the product to be printed is prone to deviation during the rotation process. This deviation will not only affect the yield of printing, but also lead to a decline in printing quality. Specifically, the rotating shaft is a key component that fixes and drives the product to be printed to rotate, and its fixing accuracy directly determines the stability and accuracy of the rotation. If the fixing accuracy of the rotating shaft itself is not high, then during the high-speed rotation process, even a small deviation will be magnified, causing the position of the product to be printed to shift. The impact of this deviation on printing is obvious. On the one hand, it may cause the misalignment of the printed pattern or text, making the final printing effect inconsistent with expectations; on the other hand, it may also cause uneven distribution of printing ink, resulting in a decline in the quality of the printed product. Especially in some fields that require extremely high printing accuracy, such as precision instruments, electronic products, etc., this deviation may cause serious quality problems and even affect the performance and use of the product.

[0041] Based on this, the present application improves the relevant curved screen printing device and printing equipment.
