Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital printing, and in particular to an integral welded steel frame shell structure for a digital printing machine. Background Technology
[0002] In existing technologies, the frame structure of digital printing machines mostly adopts bolted connections or partial welding assembly methods. This non-integrated structure has inherent weaknesses: First, multiple independent components are assembled by bolts, and there are gaps between the connection points. Under the vibration load of long-term operation of the equipment, loosening is likely to occur, resulting in insufficient overall rigidity and stability. It is difficult to ensure the long-term parallelism and perpendicularity between the transmission side plates, which directly affects the running accuracy of the guide belt and the printing quality.
[0003] Secondly, traditional designs often mount heat source components such as heating devices directly near or fixed to the transmission side plate. The thermal expansion and contraction generated during operation will be directly transmitted to the precision transmission components, causing thermal deformation of the frame and further impairing the dynamic accuracy of the equipment.
[0004] Furthermore, the dispersed components require individual processing and adjustment, resulting in cumbersome production processes, long assembly cycles, and reliance on the technical skills of assembly workers, making it difficult to effectively guarantee the consistency and assembly accuracy of the entire machine. Utility Model Content
[0005] The purpose of this utility model is to provide an integral welded steel frame shell structure for a digital printing machine to solve the problems mentioned in the background art.
[0006] The technical problem solved by this utility model is achieved through the following technical solution:
[0007] A digital printing machine has an integral welded steel frame shell structure, including a bottom frame, side plates, and a heating device mounting bracket. At least two support frames are fixedly installed on the bottom frame, and fixed brackets are fixedly installed on the support frames. Side plates for mounting transmission components are installed on the fixed brackets located at the outermost ends of the bottom frame. A first crossbar is fixedly installed between the fixed brackets, and the heating device mounting bracket is fixedly installed between the first crossbar and the side of the bottom frame.
[0008] Preferably, the heating device mounting bracket includes an outer frame rod, a second crossbar, and a short rod support. The outer frame rod is fixedly connected to the support frame on which the side plate is installed, and the second crossbar is installed across the outer frame rod.
[0009] Preferably, a short rod support is fixedly connected between the outer frame rod and the first crossbar.
[0010] Preferably, a fixing connecting piece 2 is fixedly connected between the upper end of the outer frame rod and the side plate.
[0011] Preferably, the side plate is provided with several pivot grooves, and the side plate is provided with a long sliding groove on the end face near the outer frame rod.
[0012] Preferably, a triangular reinforcing rib is fixedly installed between the side plate and the fixing frame.
[0013] The advantages and positive effects of this utility model are:
[0014] This utility model utilizes an integral welded steel frame shell structure to construct a high-rigidity, deformation-resistant, and stable foundation by welding the core load-bearing components such as the bottom frame, support frame, fixing frame, and side plates as a whole. This not only greatly enhances the mechanical strength and structural stability of the equipment but also enables modular installation and effective isolation of key components such as transmission, heating, and washing through precisely positioned installation points. This avoids the impact of thermal deformation and vibration on transmission accuracy, significantly reduces processing and assembly costs, and shortens debugging time. Thus, while ensuring the long-term operational accuracy and reliability of the equipment, it also improves the overall assembly efficiency, safety protection, and maintenance convenience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in an illustrative manner. Therefore, they only show the components related to the present invention.
[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.
[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "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 mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:
[0023] Please see Figure 1-3This utility model provides an embodiment of an integral welded steel frame shell structure for a digital printing machine, including a base frame 10. The integrally welded base frame forms a solid "foundation" that can effectively resist torsion and deformation, providing a reliable reference surface for the upper structure. Two support frames 11 are fixedly installed on the base frame 10, and the two support frames 11 are symmetrically distributed about the center line of the base frame 10. Each support frame 11 is fixedly installed with a fixing frame 12, and a side plate 16 is fixedly installed on the fixing frame 12. The side plate 16 is divided into left and right sides. The fixing frame serves as the mounting base for the side plate, and its key function is to "extend" the mounting surface of the side plate from the support frame, providing a mounting surface for the transmission of the side plate. The moving components provide a wider installation and operating space. Some components driven by the digital printing machine are installed between the left and right side plates. It should be noted that, in this embodiment, the side plate 16 is provided with several shaft grooves 21, and the side plate 16 is provided with a long strip groove 22 on the end face near the outer frame rod 18. The shaft grooves 21 are used to install transmission components such as drive shafts, while the long strip groove 22 is used to install washing cloth roller components, providing adjustment margins and facilitating installation, tensioning and maintenance. A first crossbar 15 is fixedly installed between the fixed frames 12, and a heating device mounting bracket for the heating device of the digital printing machine is installed between the first crossbar 15 and the side of the bottom frame 10.
[0024] It should be noted that, in this embodiment, the heating device mounting bracket includes an outer frame rod 18, a second crossbar 17, and a short rod support 19. The outer frame rod 18 is fixedly connected to the support frame 11 on which the side plate 16 is mounted. The second crossbar 17 is installed across the outer frame rods 18. The short rod support 19 is fixedly connected between the outer frame rod 18 and the first crossbar 15. A fixing connecting piece 20 is fixedly connected between the upper end of the outer frame rod 18 and the side plate 16. This avoids the weight and vibration of the heating device being directly transmitted to the precision transmission side plate, preventing the heating device from undergoing thermal expansion and contraction. This independent mounting bracket can absorb some thermal deformation without directly applying stress to the core transmission components, thus helping to maintain transmission accuracy.
[0025] It is worth mentioning that, in this embodiment, in order to make the side plate 16 more stable, a triangular reinforcing rib 13 is fixedly connected between the side plate 16 and the fixing frame 12 for support, and a fixing connecting piece 14 is also distributed and fixed on the fixing frame 12. Adding a triangular reinforcing rib at the connection between the side plate and the fixing frame can greatly enhance the bending and torsional resistance of the connection point and prevent the side plate from shaking or deforming under long-term stress. This is a key detail to ensure transmission accuracy.
[0026] In practice, key components of the digital printing equipment, such as the "washing device," "sheet metal shell," "heating device," and "transmission components," are installed on the aforementioned welded steel frame shell structure. This reduces processing costs and time during manufacturing and installation. The relative positions of each installation point are precisely determined upon completion of welding, thus saving significant debugging time during manual assembly and further accelerating the assembly progress of the entire machine. It also improves the overall assembly accuracy and integrity of the equipment, providing a strong guarantee for its stable operation. This structure has significant advantages in mechanical strength and structural stability, providing a solid and reliable load-bearing foundation for the subsequent installation of various functional devices. The water washing device is used to clean residual ink from the guide belt, ensuring its cleanliness. The sheet metal casing enhances the overall aesthetics, making the equipment look neater and more professional. It also provides protection, isolating critical internal components from the outside environment to prevent dust and debris from entering the equipment. Furthermore, it prevents operators from accidentally contacting the moving parts, greatly increasing operational safety. The heating device heats the adhesive on the guide belt, increasing its adhesion through precise temperature control, allowing the fabric to adhere more smoothly and pass more evenly through the nozzles. The transmission components provide power and tension to the guide belt. Ensuring the stable and reliable performance of these components is crucial to maintaining appropriate tension and stable movement of the guide belt, guaranteeing smooth operation of the entire processing flow.
[0027] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
