Description

Technical Field

[0001] This utility model relates to the field of rubber belt production technology, specifically to an adaptive mold connection transmission mechanism. Background Technology

[0002] In the rubber belt manufacturing industry, the mold drive at the molding station is a crucial component. Due to the use of molds of varying diameters and the high frequency of mold clamping during production, the connection between the mold and the transmission mechanism faces significant challenges. Traditionally, the connection between the mold head and the transmission head relies on manual alignment to ensure a reliable connection. However, this manual alignment not only increases the workload of operators but is also prone to inaccurate alignment due to human factors, thus affecting production efficiency and product quality. Furthermore, frequent manual intervention reduces the level of automation, failing to meet the demands of modern industry for efficient and precise production. The current technology lacks a transmission mechanism that can automatically adapt to changes in the mold interface and achieve a fast and reliable connection, which has become a significant bottleneck restricting the improvement of production efficiency. Therefore, developing a transmission mechanism that can adapt to mold interfaces and achieve automatic connection is of great significance for improving the automation level and production efficiency of the rubber belt manufacturing industry. Utility Model Content

[0003] This invention addresses the problem of complex and inefficient manual alignment operations in the transmission drive of molds of different diameters at the molding station in the rubber belt manufacturing industry. To resolve this, an adaptive mold connection transmission mechanism is proposed. This mechanism achieves automatic connection between the mold and the transmission head through the cooperation of mechanical structure and spring force, avoiding manual intervention and improving production efficiency.

[0004] This utility model provides an adaptive mold connection transmission mechanism, including a drive spindle, a drive shaft connector, a drive pin, and related auxiliary components. The drive spindle, as the core component for power transmission, has a drive shaft connector at its front end for connecting to the mold interface. A drive pin is mounted on the drive shaft connector, which can move within a certain range and adaptively adjust itself through spring force. Furthermore, the mechanism internally includes a first slide groove and a second slide groove, respectively guiding the movement path of a sliding rod. The sliding rod is connected to the drive pin and fixed by a sliding seat, allowing it to slide stably within the slide groove. In particular, the cooperation between the rotating shaft and the clamping wheel enhances the flexibility and reset capability of the drive pin.

[0005] Furthermore, the specific operation process of the drive pin is as follows: S1, the drive spindle advances along the slide table under the action of external power; S2, when the drive pin fails to directly align with the mold drive notch, the drive pin is squeezed, the clamping wheel spring is compressed, and the drive pin retracts; S3, the spindle continues to rotate, and when the drive pin rotates to the position corresponding to the mold drive notch, under the action of spring force, the drive pin automatically springs into the mold notch, completing the drive connection. This operation process, through the synergistic action of spring force and mechanical structure, achieves precise positioning and automatic connection of the drive pin.

[0006] Specifically, the movement path of the drive pin is guided by both the first and second slide grooves. The sliding rod is connected to the drive pin and slides within the slide groove, ensuring the stability of the drive pin during movement. Furthermore, the design of the sliding seat makes the movement of the sliding rod within the slide groove smoother, avoiding offset or jamming caused by external force interference. In addition, the cooperation between the rotating shaft and the clamping wheel not only enhances the flexibility of the drive pin but also provides additional reset capability, allowing the drive pin to retract promptly and find a new alignment position if it is not aligned with the mold notch.

[0007] Furthermore, the spring force is specifically implemented as follows: the drive pin is connected to the sliding rod via a return spring, one end of which is fixed to the sliding seat, and the other end contacts the sliding rod. When the drive pin is compressed, the return spring is compressed, storing elastic potential energy; when the drive pin rotates to the position corresponding to the mold notch, the return spring releases the elastic potential energy, pushing the drive pin to automatically spring into the mold notch. The design of the return spring ensures that the drive pin has sufficient elasticity and sensitivity during operation.

[0008] In particular, the mechanism features a compact and reliable overall design, with all components working collaboratively to ensure the stability of the transmission connection. The drive spindle connects to the mold interface via a drive shaft connector, and the drive pin achieves adaptive adjustment through the combination of spring force and mechanical structure, eliminating the need for traditional manual alignment. Furthermore, the mechanism is suitable for molds of different diameters, meeting diverse production needs and exhibiting high versatility.

[0009] The beneficial effects of this invention are as follows: through the cooperation of spring force and mechanical structure, the drive pin can automatically adjust its position and complete the connection when the mold drive notch is not completely aligned, avoiding manual intervention and significantly improving operating efficiency. Furthermore, the overall design is compact and reliable, with all components working together to ensure the stability of the transmission connection. In addition, this mechanism is suitable for molds of different diameters, has high versatility, reduces manual operation, and lowers labor intensity and human error. In summary, the adaptive mold connection transmission mechanism provided by this invention, through ingenious design, achieves automatic connection between the mold and the transmission head, effectively improving production efficiency and operational convenience, and has broad application prospects.

[0010] Furthermore, the mechanism can be further optimized in practical applications through the following methods: the material selection and surface treatment process of the drive pin can further improve its wear resistance and fatigue resistance; the fit clearance between the sliding rod and the sliding seat can be precision machined to improve sliding accuracy; the elastic coefficient of the return spring can be adjusted according to actual needs to meet the connection requirements of different mold interfaces. These optimization measures can further improve the performance and reliability of the mechanism without changing the overall technical solution.

[0011] In particular, the structural design of the mechanism fully considers the specific needs of the rubber belt manufacturing industry. Through the adaptive adjustment function of the drive pin, it solves the problem of manual alignment after mold clamping. Furthermore, the automated connection function of the mechanism not only improves production efficiency but also reduces human error, thereby enhancing product quality and consistency. In addition, the versatility of this mechanism allows it to adapt to molds of different diameters, meeting diverse production needs.

[0012] In summary, this utility model, through detailed structural design and technical solution description, provides an adaptive mold connection transmission mechanism that solves the problems existing in the prior art and realizes the automatic connection between the mold and the transmission head. The innovation of this mechanism lies in achieving adaptive adjustment and precise positioning of the drive pin through the synergistic effect of spring force and mechanical structure. It also possesses advantages such as simple structure, high reliability, and wide applicability, and has significant industrial application value. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides an adaptive mold connection transmission mechanism with a compact structure and a clear operating principle, which can effectively solve the transmission drive problem of molds of different diameters at the molding station in the rubber belt manufacturing industry. The following is in conjunction with the appendix... Figure 1 To be continued Figure 4 The accompanying drawings include the specific reference numerals for each component, and a detailed explanation of the specific implementation method and operating principle of the mechanism.

[0022] The adaptive mold connection transmission mechanism mainly includes key components such as a drive spindle 1, a drive shaft connector 2, a drive pin 4, a sliding rod 6, a sliding seat 7, a return spring 8, a rotating shaft 9, a clamping wheel 10, and a slide rail 11. These components, through the coordinated operation of their mechanical structure, achieve the automatic adjustment and precise positioning of the drive pin 4. In practical applications, the drive spindle 1, as the core component for power transmission, has a drive shaft connector 2 at its front end for docking with the mold interface. The drive pin 4 is mounted on the drive shaft connector 2, and can move along a certain path under the guidance of the first slide rail 3 and the second slide rail 5, and completes adaptive adjustment through the elastic action of the return spring 8.

[0023] S1 drives the spindle 1 forward along the slide table under the action of an external power source, at which point the drive pin 4 is in its initial position. Due to potential deviations in the position of the mold interface, the drive pin 4 may not be able to directly enter the mold drive notch during its forward movement. When the drive pin 4 fails to align with the mold drive notch, it will be subjected to pressure from the mold surface, causing the top roller 10 to roll, compressing the return spring 8, and retracting the drive pin 4 to avoid a hard collision. During this process, the retraction of the drive pin 4 is stably achieved through the cooperation of the sliding rod 6 and the sliding seat 7, ensuring that the drive pin 4 always moves along the slide 11 without any deviation or jamming.

[0024] S2 drives the main shaft 1 to continue rotating, causing the drive pin 4 to rotate synchronously. During rotation, the drive pin 4 gradually approaches the corresponding position of the mold drive notch. When the drive pin 4 rotates to be completely aligned with the mold drive notch, the return spring 8 releases its stored elastic potential energy, pushing the drive pin 4 forward along the slide 11 and accurately embedding it into the mold drive notch, completing the drive connection. During this process, the cooperation between the rotating shaft 9 and the clamping wheel 10 enhances the flexibility of the drive pin 4, enabling it to quickly respond to changes in spring force and complete precise positioning.

[0025] After the drive pin 4 is engaged with the mold drive notch, the drive spindle 1 transmits power to the mold through the drive shaft connector 2, thereby achieving the rotational drive of the mold. At this time, the connection between the drive pin 4 and the mold drive notch is maintained by the elastic force of the return spring 8, ensuring the stability of the transmission process. Throughout the entire operation, the first slide groove 3 and the second slide groove 5 provide a precise guide path for the sliding rod 6, ensuring that the movement of the drive pin 4 remains within a predetermined range and avoiding deviations caused by external interference.

[0026] To further enhance the reliability of the mechanism, the design of the sliding rod 6 and the sliding seat 7 fully considers sliding accuracy and stability. The sliding rod 6 is connected to the drive pin 4, and its movement path is jointly controlled by the first slide groove 3 and the second slide groove 5, ensuring that the drive pin 4 remains stable during movement. The sliding seat 7 is fixed within the slide rail 11, serving as support and limiting, preventing the sliding rod 6 from shaking or deviating from its predetermined track during movement. In addition, one end of the return spring 8 is fixed to the sliding seat 7, and the other end contacts the sliding rod 6. Through elastic deformation, it realizes the retraction and reset action of the drive pin 4, thereby ensuring that the drive pin 4 can respond promptly to changes in the position of the mold drive notch.

[0027] In practical applications, this mechanism is suitable for molds of different diameters, meeting diverse production needs. While the position of the drive notch may vary slightly for molds of different diameters, this mechanism, through the adaptive adjustment function of drive pin 4, can automatically find and embed itself into the mold drive notch without manual intervention. This feature significantly improves production efficiency, reduces alignment time after mold clamping, and minimizes the impact of human error on product quality.

[0028] Furthermore, the mechanism boasts a compact and reliable overall design, with components working collaboratively to ensure stable transmission connections. The drive spindle 1 connects to the mold interface via the drive shaft connector 2, and the drive pin 4 achieves adaptive adjustment through the cooperation of the return spring 8 and the mechanical structure, eliminating the need for traditional manual alignment. The cooperation between the clamping wheel 10 and the rotating shaft 9 not only enhances the flexibility of the drive pin 4 but also provides additional reset capability, allowing the drive pin 4 to retract promptly and re-find its alignment position if it is misaligned with the mold notch. This design gives the mechanism high versatility when dealing with different molds and can adapt to various production scenarios.

[0029] In its implementation, the mechanism operates as follows: First, the drive spindle 1 advances along the slide under the action of an external power source, and the drive pin 4 moves forward accordingly. If the drive pin 4 fails to align directly with the mold drive notch, it is compressed by the mold surface, the return spring 8 is compressed, and the drive pin 4 retracts. Next, the drive spindle 1 continues to rotate, causing the drive pin 4 to rotate synchronously until it aligns with the mold drive notch. At this point, the return spring 8 releases its elastic potential energy, and the drive pin 4 automatically pops out and embeds itself into the mold drive notch, completing the drive connection. Finally, the drive spindle 1 transmits power to the mold through the drive shaft connector 2, realizing the rotation drive of the mold.

[0030] The operating principle and motion of this mechanism are achieved through the synergistic effect of spring force and mechanical structure, avoiding manual intervention and significantly improving operational efficiency. The overall design is compact and reliable, with all components working together to ensure the stability of the transmission connection. Furthermore, this mechanism is applicable to molds of different diameters, exhibiting high versatility, reducing manual operation, labor intensity, and human error. In summary, the adaptive mold connection transmission mechanism provided by this utility model achieves automatic connection between the mold and the transmission head through ingenious design, effectively improving production efficiency and operational convenience, and has broad application prospects.

[0031] In actual production, the performance of this mechanism can be further improved by optimizing material selection and processing technology. For example, the material of the drive pin 4 can be a high-strength, wear-resistant material, specifically high-manganese steel, to improve its service life and fatigue resistance. The clearance between the sliding rod 6 and the sliding seat 7 can be further reduced through precision machining to improve sliding accuracy and stability. The elastic coefficient of the return spring 8 can be adjusted according to actual needs to meet the connection requirements of different mold interfaces. These optimization measures can further improve the performance and reliability of the mechanism without changing the overall technical solution, meeting higher production demands.

[0032] In summary, this utility model, through detailed structural design and technical solution description, provides an adaptive mold connection transmission mechanism that solves the problems existing in the prior art and realizes the automatic connection between the mold and the transmission head. The innovation of this mechanism lies in achieving adaptive adjustment and precise positioning of the drive pin 4 through the synergistic effect of spring force and mechanical structure. It also possesses advantages such as simple structure, high reliability, and wide applicability, and has significant industrial application value.
