Description

Technical Field

[0001] This utility model relates to the field of roller technology, specifically to a roller for pressing natural rubber into thin sheets. Background Technology

[0002] Natural rubber thinning is a crucial step in the initial processing of rubber. Its core task is to use mechanical extrusion to thin out latex lumps or clumps that are saturated with a large amount of water, and to effectively dehydrate them, thus laying a good foundation for subsequent drying and molding processes.

[0003] However, some existing rollers generate continuous and intense friction with the rubber during the thinning operation of natural rubber. This process generates a lot of heat, causing the roller temperature to rise sharply. Excessive temperature can easily cause the rubber to stick to the roller surface, affecting the normal thinning process, resulting in a significant reduction in production efficiency. At the same time, it will accelerate the aging of the rubber and reduce the quality of rubber products. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-4 As shown, a roller for thinning natural rubber includes a rotating shaft 1, with shaft heads on both sides of the rotating shaft 1, which facilitates the connection between the rotating shaft 1 and the transmission components, and also facilitates the subsequent thinning process of natural rubber.

[0016] A rolling shell 2 is fixedly connected to the surface of the rotating shaft 1. The rolling shell 2 is used to directly contact the natural rubber to compress the natural rubber.

[0017] The inner wall of the rolling shell 2 is provided with a circulation mechanism 3, which can perform preliminary cooling treatment on both sides of the surface of the rolling shell 2, thereby effectively reducing the temperature of the surface of the rolling shell 2.

[0018] The circulation mechanism 3 includes a first water inlet pipe 31 fixedly connected to the inner wall of the rolling shell 2. One end of the first water inlet pipe 31 is connected to a heat transfer pipe 32. There are two heat transfer pipes 32, and they are designed in a spiral shape. The heat transfer pipes 32 with special shape design can effectively increase the heat exchange area and improve the heat transfer efficiency.

[0019] One end of one heat transfer tube 32 is connected to a connecting tube 33, one end of the connecting tube 33 is connected to one end of another heat transfer tube 32, and one end of the other heat transfer tube 32 is connected to a first water outlet tube 34.

[0020] By connecting the pipe 33, the two originally independent heat transfer pipes 32 can be connected to form a continuous fluid channel, so that the heat transfer medium can flow through the two heat transfer pipes 32 in sequence, ensuring the orderly flow of the medium and realizing a complete heat exchange cycle.

[0021] Both the first inlet pipe 31 and the first outlet pipe 34 are provided with a first rotary joint 4. By setting the first rotary joint 4, the rolling shell 2 can maintain the sealed connection between the first inlet pipe 31, the first outlet pipe 34 and the subsequent water pipe while rotating freely, ensuring that the heat transfer medium can flow continuously and stably without affecting the normal operation of the rolling shell 2.

[0022] The inner wall of the rolling shell 2 is fixedly connected to a second water inlet pipe 5, and one end of the second water inlet pipe 5 is connected to a heat exchange pipe 6.

[0023] The heat exchange tube 6 has a spiral structure design, and its diameter is larger than that of the heat transfer tube 32. Since the heat exchange tube 6 is located in the critical area where the rolling shell 2 contacts the natural rubber, the larger diameter heat exchange tube 6 can concentrate and enhance the cooling of this high-temperature area. This allows the heat generated in the contact area to be quickly dissipated, reducing the possibility of excessively high local temperatures in the rolling shell 2 due to heat accumulation. This ensures that the natural rubber can be pressed thin under suitable temperature conditions, thus improving product quality.

[0024] One end of the heat exchange tube 6 is connected to a second water outlet tube 7, which facilitates the discharge of the water after heat exchange.

[0025] The surfaces of the second inlet pipe 5 and the second outlet pipe 7 are both provided with a second rotary joint 8. By setting the second rotary joint 8, the rolling shell 2 can maintain the sealed connection between the second inlet pipe 5, the second outlet pipe 7 and the subsequent water pipe while rotating freely.

[0026] The inner wall of the heat exchange tube 6 is provided with a flow turbulence mechanism 9. There are several flow turbulence mechanisms 9. By setting the flow turbulence mechanism 9, the water flow can fully contact the inner wall of the heat exchange tube 6, thereby effectively enhancing the heat exchange efficiency of the heat exchange tube 6, reducing the unnecessary energy loss, reducing operating costs, and making the heat exchange process more stable.

[0027] The turbulence mechanism 9 includes a connecting frame 91 fixedly connected to the inner wall of the heat exchange tube 6. There are three connecting frames 91, which facilitates the connection of subsequent components.

[0028] One end of the connecting frame 91 is fixedly connected to the connecting column 92, and the top of the connecting column 92 is fixedly connected to the guide block 93. The guide block 93 is designed with an inclined structure. Through the setting of the guide block 93 and the connecting column 92, a strong disturbance force can be generated to the water flow, breaking its laminar flow state and making it turbulent. This allows water flows of different layers to fully contact the inner wall of the heat exchange tube 6, effectively improving the heat exchange efficiency of the heat exchange tube 6.

[0029] It is worth noting that the technical features such as the first rotary joint 4 and the second rotary joint 8 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0030] Working principle: First, an external water source is connected to the first water inlet pipe 31 and the second water inlet pipe 5. At this time, the water in the inner cavity of the first water inlet pipe 31 will flow out from the first water outlet pipe 34 through the heat transfer pipe 32 and the connecting pipe 33, thereby cooling the two sides of the surface of the rolling shell 2 and effectively alleviating the rising trend of the temperature on both sides.

[0031] Meanwhile, the water flowing inside the second inlet pipe 5 will be discharged from the second outlet pipe 7 through the heat exchange pipe 6. When the water flows inside the heat exchange pipe 6, the specially shaped guide block 93 will generate a strong interference force on the water flow, breaking the laminar flow state and causing the water flow to generate strong turbulence. This allows water from different layers to come into contact with the inner wall of the heat exchange pipe 6, thereby improving the heat exchange efficiency, reducing the large temperature difference between the fluid near the pipe wall and the fluid at the center of the pipe, making the heat exchange process more stable, and thus effectively improving production efficiency. It also reduces the situation where natural rubber sticks to the surface of the rolling shell 2, making the production process smoother.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] 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.
