Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-cooled roller technology, specifically to a non-driven water-cooled roller mechanism. Background Technology
[0002] In the printing industry, cooling rollers play a crucial role in ensuring the quality of printed materials. With the continuous development of printing technology, the demands for printing speed and quality are increasing, making the performance of cooling rollers increasingly important. In traditional printing processes, such as offset and gravure printing, ink needs to dry and cure quickly after being printed onto paper or other substrates to avoid ink smudging and other problems, thus ensuring the clarity and vibrancy of the printed image. Cooling rollers, through close contact with the printed paper, remove heat from the ink, accelerating the drying process and improving the quality of the printed material. However, the application of traditional cooling roller mechanisms relying on external drive devices in the printing industry presents several problems. From the perspective of equipment cost and maintenance, the procurement, installation, and subsequent maintenance costs of components such as drive motors, transmission chains, and pulleys are high. Printing companies need to employ professional technicians to regularly inspect and maintain these drive components, such as replacing motor brushes and adjusting transmission chain tension. This undoubtedly increases the company's human and material costs. Moreover, if these drive components malfunction, such as motor burnout or chain breakage, it will lead to cooling roller failure. When the cooling roller stops working, it causes the entire printing production line to stagnate, severely impacting production progress and causing economic losses to the company. Regarding the working environment, the noise and vibration generated by the driven cooling roller mechanism cannot be ignored. Printing workshops typically require a relatively quiet environment so that operators can accurately judge the equipment's operating status and promptly identify problems during the printing process. However, the noise generated by the cooling roller drive components can interfere with the operator's auditory judgment, affecting work efficiency and quality. Simultaneously, vibrations may be transmitted to other components of the printing equipment, such as the plate cylinder and rubber cylinder, leading to misregistration and other printing quality problems, reducing the pass rate of printed products. Furthermore, for some small printing companies or printing workshops with special requirements for equipment layout, space is often limited. Traditional driven water-cooled roller mechanisms, due to their complex drive components, occupy a large amount of space, greatly restricting the installation and layout of the equipment. Companies may need to spend more time and effort planning the equipment placement, and may even be unable to select higher-performance cooling roller equipment due to insufficient space, thus restricting the company's production capacity and product quality improvement to a certain extent.

[0007] Preferably, the mounting plate is concentric with the water-cooled roller, and the mounting plate is hollow.
[0008] The above technical solution enables the mounting plate to rotate concentrically with the water-cooled roller.
[0009] Preferably, the guide plate has a spiral design, and the outer surface of the guide plate is in contact with the inner surface of the water-cooled roller.
[0010] By adopting the above technical solution, the guide plate can guide the cooling water in a spiral direction.
[0011] Preferably, the guide plate is hollow, and both ends of the guide plate are fixedly connected to the outer surfaces of the two mounting plates facing each other.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the non-driven water-cooled roller mechanism:
[0018] 1. By eliminating complex external drive devices, such as motors, transmission chains, and pulleys, the subsequent regular maintenance and repair costs of these components are avoided, while production downtime caused by drive component failures is reduced, thus improving production efficiency and economic benefits.
[0019] Furthermore, since there is no noise or vibration generated by the operation of driving components, noise pollution to workplaces such as printing workshops is greatly reduced, providing operators with a relatively quiet and comfortable working environment, allowing them to focus more on production operations. At the same time, it avoids the adverse effects of vibration on equipment stability and printing accuracy, which helps to improve product quality, reduce the defect rate caused by environmental factors, and improve the stability and reliability of production.
[0020] Furthermore, in application scenarios with limited space or high requirements for equipment simplicity, the driveless design makes its structure more compact and concise. It eliminates the need to consider the installation space and layout limitations of drive components, enabling it to adapt more flexibly to various complex work sites and production needs. This allows enterprises to quickly install and adjust the layout of equipment according to actual conditions, thereby improving the versatility and practicality of the equipment and providing more choices and convenience for enterprises' production planning and equipment upgrades.
[0021] 2. By directing the flow of cooling water into the water-cooled roller, the heat exchange efficiency between the cooling water and the inner surface of the water-cooled roller is increased during the flow of the cooling water in the water-cooled roller, thereby enabling the water-cooled roller to cool the product more effectively.

[0027] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-4 This utility model provides a technical solution: a non-driven water-cooled roller mechanism.
[0029] Example 1
[0030] This embodiment discloses: a water-cooled roller 1, with an inlet pipe 2 fixedly installed at one end of the water-cooled roller 1 and an outlet pipe 3 fixedly installed at the other end of the water-cooled roller 1. An installation plate 4 is provided at the end of the inlet pipe 2 and the outlet pipe 3 away from the water-cooled roller 1, and an installation hole 5 is provided at the upper end of the installation plate 4, and a bearing 6 is installed at the lower end of the installation plate 4.
[0031] The water-cooled roller 1 is connected to the bearing 6 through the water inlet pipe 2 and the water outlet pipe 3. The water-cooled roller 1, the water inlet pipe 2 and the water outlet pipe 3 are concentrically arranged, and the two ends of the water-cooled roller 1 are respectively connected to the water inlet pipe 2 and the water outlet pipe 3.
[0032] During use, the mounting plate 4 is fixedly installed to the frame of the printing equipment through the mounting holes 5. The water-cooled roller 1 comes into contact with the material and rotates relative to the mounting plate 4 through the bearing 6 driven by the material. Cooling water is injected into the water-cooled roller 1 through the water inlet pipe 2. The cooling water carries away the heat from the surface of the water-cooled roller 1 and is discharged through the water outlet pipe 3, thus achieving the cooling of the material.
[0033] Example 2
[0034] This embodiment discloses, based on embodiment 1, that: mounting plates 7 are fixedly installed inside both ends of the water-cooled roller 1, and a guide plate 8 is fixedly installed between the two mounting plates 7; a central rod 9 is fixedly installed in the middle of the guide plate 8; a central hole 10 is opened inside the central rod 9; and a connecting hole 11 is opened on the outer surface of the guide plate 8.
[0035] The mounting plate 7 is concentric with the water-cooled roller 1, and the mounting plate 7 is hollow.
[0036] The guide plate 8 has a spiral design, and the outer surface of the guide plate 8 is in contact with the inner surface of the water-cooled roller 1.
[0037] The guide plate 8 is hollow, and both ends of the guide plate 8 are fixedly connected to the outer surfaces of the two mounting plates 7 facing each other.
[0038] The center rod 9 is concentrically set with the guide plate 8 and the mounting plate 7. The two ends of the center hole 10 penetrate the outer surfaces of the two mounting plates 7 respectively, and the center hole 10 is not connected to the internal cavity of the mounting plate 7.
[0039] The connecting holes 11 are evenly distributed on the outer surface of the mounting plate 7, and the internal cavity of the mounting plate 7 is connected to the internal cavity of the guide plate 8. The connecting holes 11 penetrate the outer surfaces of both sides of the mounting plate 7.
[0040] As cooling water is injected, the cold water enters the interior of the mounting plate 7 and guide plate 8, as well as the spiral cavity between the outer surface of guide plate 8 and the inner surface of water-cooled roller 1, through the connecting hole 11 on the surface of mounting plate 7. At this time, the heat exchange area is increased by the full contact between the inner surface of mounting plate 7 and guide plate 8 and cooling water, so that the cooling water can fully absorb heat and ensure the cooling effect of water-cooled roller 1 on the material. At the same time, the water flow directly delivers cooling water through the central hole 10 in the middle of the central rod 9. The central hole 10 allows the cooling water injected into water-cooled roller 1 to flow out through the central rod 9 at an accelerated speed, avoiding the large pressure exerted by the cooling water on water-cooled roller 1 when the water flow is large, which would cause deformation and damage to water-cooled roller 1.
[0041] Meanwhile, when the cooling water flows in the cavity between the outer surface of the spiral guide plate 8 and the inner surface of the water-cooled roller 1, the water-cooled roller 1, which flows in the opposite direction, assists the water-cooled roller 1 in rotating with the material, thereby enabling the water-cooled roller 1 to maintain good rotation without a drive.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
