DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] With reference to Figure 1 One Figure 3 The utility model provides a kind of printing roller balancing device for digital printing machine, including support frame 1, its main effect is to support and fix all relevant components, support frame 1 upper surface is fixedly connected with fixed frame 2, and fixed frame 2 is used to accommodate and support printing roller 3 and other components, the inner cavity of fixed frame 2 is a space that can accommodate printing roller 3, ensure that printing roller 3 can rotate freely in the process of operation, while avoiding unnecessary friction caused by axial misalignment, printing roller 3 is provided in the inside of fixed frame 2, it is transferred to the surface of cloth by rotating printing material such as ink, printing roller 3 outer wall is rotatably connected with bearing seat 4, printing roller 3 outer wall is connected with bearing seat 4, bearing seat 4 provides stable support for printing roller 3, ensure that it can keep steady rotation when working, bearing seat 4 bottom is provided with balancing component, and balancing component is used to effectively automatically adjust when printing roller 3 generates axial unbalanced force;

[0033] Balancing component includes disc spring 5, disc spring 5 one end is in contact with the lower surface of bearing seat 4, the other end is in contact with the inner wall of fixed frame 2, disc spring 5 can generate reaction force under the action of axial unbalanced force, play effective support effect, when the running state of printing roller 3 is unbalanced, disc spring 5 will change according to the size and direction of unbalanced force, adjust the stress state of printing roller 3, so as to achieve balancing effect, the lower surface of bearing seat 4 is fixedly connected with guide sleeve 6, and the action of guide sleeve 6 is to guide and balance the movement of guide column 7, ensure the movement of entire balancing system, guide sleeve 6 inner wall is slidably connected with guide column 7, one end of guide column 7 is fixedly connected in the inside of support frame 1, and buffer component is arranged on the bottom of support frame 1, and buffer component is used to reduce vibration force and noise generated in working equipment.

[0034] Specifically, when the printing roller 3 is installed on the bearing seat 4 of the digital printing machine, if the installation position deviates or the bearing is not installed properly, the original balance state of the printing roller 3 will be destroyed. The bearing seat 4 guides the movement direction of the printing roller 3 by driving the guide column 7 to slide inside the guide sleeve 6, thereby avoiding deviation or instability of the printing roller 3, so that the printing roller 3 always maintains a suitable axial position during operation, ensuring the accuracy and consistency of the printed pattern. Under the driving of the bearing seat 4, the disc spring 5 also plays a role. The main function of the disc spring 5 is to store and release the energy carried by the axial force through its elastic deformation. When the external axial force acts on the bearing seat 4, the disc spring 5 is elastically compressed, causing the distance between the discs to decrease. In this process, the applied axial force is converted into the elastic potential energy of the disc spring 5, enabling the entire system to maintain a certain balance and stability. However, when the axial force decreases or changes direction, the disc spring 5 relies on its elastic restoring force to rebound, releasing the stored elastic potential energy. At this time, the elastic rebound of the disc spring 5 pushes the bearing seat 4 and the printing roller 3 to move in the opposite direction, allowing the system to return to a relatively stable state, ensuring the long-term stable operation of the printing machine.

[0035] Referring to Figure 4 and Figure 5 , the buffer assembly includes a transmission disc 8 and a connecting disc 9. The upper surface of the transmission disc 8 is fixedly connected to the bottom of the support frame 1, and its upper surface is tightly connected to the support frame 1 through fixed connection, serving to transmit external vibrations and impact forces. The top of the connecting disc 9 is fixedly connected to the bottom of the transmission disc 8. The connecting disc 9 is rotatably connected with a collar 10 on both sides. These collars 10 support and guide the connecting disc 9. The inner wall of the collar 10 is slidably connected with a sliding column 11, which provides a smooth movement track to ensure smooth movement of the connecting disc 9 during the buffering process. The bottom of the connecting disc 9 is fixedly connected with a sliding shaft 12, which serves as a power transmission medium between the connecting disc 9 and the compression-resistant plate 14, and helps to alleviate the transmission of vibrations. The outer wall of the sliding shaft 12 is slidably connected with a connecting ring 13.

[0036] Specifically, when the printing roller 3 of the digital printing machine is in a high-speed rotating state, even if it has high manufacturing precision and accurate installation, it is still prone to vibration due to factors such as centrifugal force. The transmission disc 8 transmits external vibrations to the surface of the connecting disc 9, which further conducts and distributes forces. Through the movement of the connecting disc 9, the transmitted vibration force is conducted to the sliding shaft 12 and the elastic gasket 15. The sliding shaft 12 is driven to slide inside the connecting ring 13, allowing axial movement to occur. At the same time, the elastic gasket 15 deforms elastically under the action of external force, effectively absorbing vibration and dispersing energy, reducing the direct impact of vibration on other components.

[0037] Referring toFigure 4 And Figure 5 The bottom of the connecting disc 9 is fixedly connected with an elastic gasket 15, the elastic gasket 15 has a certain elasticity and buffering effect, can effectively reduce the influence of vibration and impact on other parts, ensure the stability of the whole system, the bottom end of the elastic gasket 15 is fixedly connected with a support column 16, the support column 16 provides vertical support force, ensures the stability of the elastic gasket 15, and prevents excessive deformation or tilting, the bottom end of the support column 16 is fixedly connected with a compression plate 14, the compression plate 14 can effectively disperse and transfer pressure, avoid excessive stress concentration in local area, the compression plate 14 is rotatably connected with one side of the sliding column 11, the bottom of the compression plate 14 is fixedly connected with an anti-pressure shaft 17, the anti-pressure shaft 17 enhances the compression strength of the structure, and the bottom end of the anti-pressure shaft 17 is fixedly connected with a bottom disc 18.

[0038] Specifically, at the same time, the movement of the connecting disc 9 is not only limited to pushing the sliding shaft 12 and the elastic gasket 15, but also cooperates with the sleeve ring 10, when the connecting disc 9 moves, the sleeve ring 10 on both sides also shrinks inward along the movement direction of the connecting disc 9 and slides into the inside of the sliding column 11, this shrinking action can further effectively absorb the remaining vibration force and slow down the transmission of vibration, so as to realize the second round of isolation and buffering of vibration, in addition, the whole system not only improves the balance of the equipment, but also significantly reduces the noise generated during work, since the vibration force is gradually converted into elastic potential energy and absorbed by each part, the system can maintain a more stable running state, thereby reducing the influence of the vibration source on the equipment.

[0039] Working principle: when using the device, the object to be processed is printed by the printing roller 3, when the printing roller 3 works and generates unbalanced axial force, the dynamic guide column 7 can be driven to slide in the guide sleeve 6 by the bearing seat 4, the cooperation of the guide sleeve 6 and the guide column 7 not only guides the movement direction, but also makes the bearing seat 4 and the printing roller 3 always maintain in the relatively accurate axial position, under the action of the bearing seat 4, the disc spring 5 is further driven to elastically deform, so that the distance between the discs becomes smaller, in this process, the energy carried by the axial force is converted into the elastic potential energy of the disc spring 5 and stored up, on the contrary, when the axial force decreases or changes direction, the disc spring 5 relies on its elastic restoring force to rebound, releases the stored elastic potential energy, pushes the bearing seat 4 and the printing roller 3 to move in the opposite direction, and restores to the relatively stable state, thereby ensuring that the digital printing machine can complete the printing work with high quality, when the machine operates and generates large centrifugal force, the vibration force can be transmitted to the surface of the connecting disc 9 through the transmission disc 8, the force is further brought to the sliding shaft 12 and the elastic gasket 15 through the action of the connecting disc 9, so as to make the sliding shaft 12 slide in the connecting ring 13, and the elastic gasket 15 elastically deform, thereby effectively absorbing and sharing a part of the vibration force, when the connecting disc 9 moves, the sleeve ring 10 on both sides will also shrink in the sliding column 11 under the driving of the connecting disc 9, thereby effectively absorbing and slowing down the remaining vibration force, further making the equipment keep balance when working, and reducing the noise generated in the working process of the equipment.

[0040] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
