Description

Technical Field

[0001] This utility model belongs to the technical field of rubber refining machines, and in particular relates to a longitudinal cutting mechanism used in the rubber refining process. Background Technology

[0002] Rubber refining is a very important step in the rubber manufacturing process. Its main purpose is to repeatedly process rubber raw materials through a refining machine to improve their processability, increase their uniformity, and enhance their physical properties. Rubber refining machines are usually equipped with refining rollers for calendering, mixing, and refining rubber materials.

[0003] However, it has been found through long-term production processes that during the rubber refining process, the refined rubber will take on a semi-fluid form and be in sheet shape. As refining continues, some rubber will overflow from both ends of the refining rollers. At this point, longitudinal cutting is required to facilitate subsequent processing or improve production quality. To this end, practitioners have designed a longitudinal cutting mechanism for the rubber refining process. Utility Model Content

[0004] The purpose of this invention is to provide a longitudinal cutting mechanism for the rubber refining process in order to solve the problem of excessive rubber overflowing from both ends of the refining roller during the existing rubber refining process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Combination Figure 1-3 The longitudinal cutting mechanism shown includes a rubber refining mill 1, and a longitudinal cutting mechanism 2 that cooperates with the refining roller of the rubber refining mill 1 for longitudinally cutting the ends of the refined rubber.

[0026] The core of the longitudinal cutting mechanism 2 consists of two sets of opposing support base plates 201. These two sets of support base plates 201 are fixed to the rubber refining mill 1 through precise structural design to ensure the stability and load-bearing capacity of the longitudinal cutting system. Between these two sets of support base plates 201, a bidirectional threaded rod 202 is rotatably installed. The rotation of the bidirectional threaded rod 202 is driven by an adjusting motor 203 installed at one end. This motor rotates the bidirectional threaded rod 202 through a transmission system, thereby driving two sets of ball nut bases 204 on it to slide in opposite directions along the bidirectional threaded rod 202. The ball nut bases 204 adopt a ball screw structure, which has high transmission accuracy and low frictional resistance, enabling the longitudinal cutting mechanism 2 to achieve fine adjustment and control. To ensure the precise guidance of the ball nut bases 204, the bidirectional threaded rod... Below 202, a guide rod 205 is also provided. The guide rod 205 is connected to two sets of guide blocks 206 through a stable mechanical structure, forming a precision guiding system. The guide blocks 206 slide on the guide rod 205 and are connected to the ball nut base 204 located on the same vertical plane through the connecting plate 207, ensuring the synchronization and stability of the longitudinal cutting mechanism 2. The connecting plate 207 plays a connecting and supporting role, enhancing the structural strength of the entire system. On the guide block 206, a cutter assembly 208 is installed. These cutter assemblies 208 can accurately cut the overflow ends of the rubber during the refining process according to the requirements. The design of the cutter assembly 208 not only considers the cutting requirements of the rubber material, but also ensures the smoothness and efficiency of the cutting process, avoiding possible obstruction or uneven cutting phenomena.

[0027] In this embodiment, a limit ring is provided in the middle of the bidirectional threaded rod 202. This is to limit the movement of the bidirectional threaded rod 202 during use and to avoid excessive sliding and collision between the two sets of ball nut bases 204. Specifically, the design of the bidirectional threaded rod 202 may involve rotation to realize the movement function of the two sets of ball nut bases 204. If no limit ring is set when the two sets of ball nut bases 204 are running relative to each other, wear will be caused between the running collisions.

[0028] In this embodiment, the cutter assembly 208 is a key component of the longitudinal cutting mechanism 2. Its design considers high-precision cutting and stable operation. The cutter assembly 208 includes a cutter base plate 2081 fixed to the guide block 206. The cutter base plate 2081 provides a stable foundation and support for the entire cutter system. A propulsion cylinder 2082 is installed inside its cavity. The propulsion cylinder 2082 uses air pressure to provide power, pushing the cylinder extension rod to move back and forth, thereby driving the movement of the cutter support 2083. The extension rod of the propulsion cylinder is connected to the cutter support 2083, enabling movement when needed. The cutter holder 2083, as the core component supporting the cutting process, precisely drives the cutter support to perform linear motion. The cutter support 2084 is installed within its cavity, serving as the tool for the actual cutting work. A cutter motor 2085 is installed on the side wall of the cutter support 2083. The function of the cutter motor 2085 is to drive the cutter 2084 to rotate within the cutter support 2083, achieving longitudinal cutting of the rubber. The cutter motor 2085 provides rotational power, ensuring that the cutter 2084 maintains a stable speed during the cutting process, thereby achieving efficient and uniform cutting results.

[0029] To control the range of motion of the cutter support 2083, a limiting groove 2086 is designed on the side wall of the cutter base plate 2081. The function of the limiting groove 2086 is to restrict excessive movement or misalignment of the cutter support 2083 during operation, ensuring that it moves normally within a specified distance. This design not only improves cutting accuracy but also effectively avoids mechanical damage or miscutting problems that may be caused by excessive movement.

[0030] In summary, the multiple designs of the 208 cutting assembly ensure cutting accuracy, stability, and operational safety during the rubber refining process. The precise coordination of each component makes the cutting process more efficient and precise, meeting the stringent requirements of the production line for rubber refining.

[0031] In this embodiment, the diameter of the cutter 2084 is greater than the height of the cutter base plate 2081, ensuring that it can cut deeper materials during actual operation. At the same time, the height of the cutter base plate 2081 is relatively small, mainly serving as support and fixation. Although the height of the cutter base plate 2081 is lower than the diameter of the cutter 2084, this design can effectively reduce the volume and weight of the overall structure, which is conducive to the compact layout of the system. The smaller height also helps to lower the overall center of gravity of the equipment, improving its stability and shock resistance during operation.

[0032] Example 2: The cutter assembly 208 in this example 2 is an improvement on the above example. The technical content disclosed in the above example will not be described again. The content of the above-disclosed example is also part of the content disclosed in this example 2.

[0033] One embodiment of the present invention, in conjunction with Figure 4 The cutter assembly 208 shown includes a cutter base plate 2081 fixed to a guide block 206. Several sets of propulsion cylinders 2082 are disposed within the cavity of the cutter base plate 2081. A cutter bracket 2083 is disposed on the telescopic rod of the propulsion cylinders 2082. Several sets of cutters 2084 are disposed within the cavity of the cutter bracket 2083. A cutter motor 2085 is disposed on the side wall of the cutter bracket 2083 to drive the rotation of the several sets of cutters 2084. Unlike Embodiment 1, Embodiment 2 adds multiple sets of propulsion cylinders 2082 and cutters 2084. This solution ensures that, due to the operation of one set of cutters 2084, some rubber may occasionally not be completely cut, causing a certain impact on the operation of subsequent equipment. However, the multiple sets also bring a new problem: increased manufacturing costs and difficulty in subsequent maintenance. Furthermore, it is impossible to add a limiting groove 2086 as in Embodiment 1 to simultaneously limit multiple sets of cutters 2084, and abnormal noise may occur during the propulsion and retraction process.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
