[0046] Figure 2 The present invention illustrates a rotary drive mechanism 1 in some embodiments. The rotary drive mechanism 1 is mounted on a frame 2 and includes a drive device 11, a transmission device 12, and at least one rotary device 13. The drive device 11 is mounted on the frame 2. The transmission device 12 is mounted on the frame 2 and is driven to the drive device 11.

[0047] like Figure 4 As shown, the rotating device 13 includes a rotating base 131 and a connecting component 132. The rotating base 131 is rotatably mounted on the frame 2. The rotating base 131 is driven to be connected to the transmission device 12. The connecting component 132 is connected to the rotating base 131 and the mold shell 3 respectively, forming a stable power transmission path.

[0048] like Figure 6 , Figure 7 As shown, the drive device 11 drives the rotating seat 131 to rotate via the transmission device 12, thereby connecting the assembly 132 to drive the mold shell 3 to rotate. Furthermore, the drive device 11 can be configured as a component with adjustable output speed, allowing the rotation speed of the rotating seat 131 to be adjusted via the drive device 11, achieving continuous uniform rotation or variable speed rotation of the mold shell 3. This facilitates uniform heating of all surfaces of the mold shell 3, improving drying quality and efficiency.

[0049] It should be noted that the rotary drive mechanism 1 can be configured to include a single rotating device 13 or multiple rotating devices 13 in different embodiments. Specifically, multiple rotating devices 13 can be driven to rotate simultaneously by a single drive device 11, or each rotating device 13 can be configured to be driven by a single drive device 11, depending on the actual design and application requirements. The specific number of rotating devices 13 can be adaptively adjusted according to actual production needs and equipment layout.

[0050] Understandably, the drive device 11 is used to connect to the transmission device 12 and provide driving force to the transmission device 12, and can be a power source such as an electric motor, hydraulic motor, or pneumatic motor; the transmission device 12 is used to connect to the rotating device 13 and transmit the power of the drive device 11 to the rotating device 13, and can be a transmission form such as gear transmission, chain transmission, or belt transmission; the rotating seat 131 of the rotating device 13 is used to receive the driving force transmitted from the transmission device 12 and generate rotational motion; the connecting component 132 is used to connect the rotating seat 131 and the mold shell 3, and transmit the rotational motion to the mold shell 3, ensuring that the mold shell 3 rotates synchronously with the rotating seat 131. Specifically, during the rotation process, each surface of the mold shell 3 can periodically face the drying air source. When combined with the drying source such as heating and blowing provided by the external drying system, the rotational motion can ensure that each surface of the mold shell 3 can obtain a basically consistent drying time, effectively avoiding the problem of uneven drying caused by fixed position. In this embodiment, by setting a rotary drive mechanism 1, the stable rotation of the mold shell 3 is achieved, which provides a basic guarantee for the uniform drying of the mold shell 3. When combined with an appropriate drying system, it can effectively improve the drying uniformity of the surface of the mold shell 3 and improve the drying efficiency.

[0051] like Figure 2 , Figure 4 As shown, in some embodiments of the rotary drive mechanism 1, the rotary drive mechanism 1 includes a plurality of rotary devices 13, each rotary device 13 further includes a support member 133, each support member 133 is respectively disposed on the frame 2, each rotary seat 131 is rotatably disposed on each support member 133 in a corresponding manner, and the transmission device 12 is driven and connected to each rotary seat 131.

[0052] like Figure 6 As shown, when the drive device 11 drives each rotating seat 131 to rotate through the transmission device 12, each rotating seat 131 drives each mold shell 3 to rotate in a corresponding manner.

[0053] It should be noted that each rotating seat 131 is individually mounted on a support member 133, forming an independent rotating support unit; the transmission device 12 is connected to each rotating seat 131 as a linkage mechanism, wherein the transmission device 12 can be a synchronous belt pulley system, a sprocket system or a gear system, etc., to ensure that each rotating seat 131 rotates synchronously; each rotating seat 131 drives each mold shell 3 to rotate one by one through its respective connecting component 132, that is, each rotating seat 131 specifically drives one mold shell 3, thereby forming an independent driving unit.

[0054] Understandably, the support member 133 is used to provide a stable mounting base and radial support for the rotating seat 131, ensuring the smooth rotation of the rotating seat 131; each rotating seat 131 drives its respective mold shell 3 to rotate synchronously through the connecting component 132, ensuring that each mold shell 3 can obtain rotational motion; by setting multiple rotating devices 13, a single drive device 11 can drive multiple mold shells 3 to rotate simultaneously, which significantly improves the equipment's processing capacity and space utilization, and improves production efficiency while reducing production energy consumption.

[0055] It should be noted that the transmission ratio between the transmission device 12 and each rotating seat 131 can be flexibly set, so that the rotational speed of each rotating seat 131 can be adjusted according to actual usage requirements. For example, the rotational speed of each rotating seat 131 can be configured to be the same; the rotational speeds of all rotating seats 131 can be configured to be different; or only some rotating seats 131 can be configured to have different rotational speeds.

[0056] like Figure 2 As shown, in some embodiments of the rotary drive mechanism 1, the drive end of the drive device 11 is provided with a drive wheel 111, which is driven and connected to the transmission device 12.

[0057] In one optional embodiment, please refer to the following: Figures 4 to 6 The drive wheel 111 is configured as a drive sprocket. The transmission device 12 includes a chain 122, and the drive sprocket is driven and connected to the chain 122 by tooth meshing. The rotating device 13 also includes a sprocket 134, which is disposed on the rotating base 131. The chain 122 is wound around the drive sprocket and the sprocket 134 to form a closed-loop transmission circuit, so that the chain 122 is driven to move by the drive sprocket, thereby driving the sprocket 134 and the rotating base 131 to rotate synchronously. The installation method of the sprocket 134 includes, but is not limited to, the following two implementation schemes: one is to manufacture the sprocket 134 and the rotating base 131 into an integral part by a one-piece molding process; the other is to manufacture the sprocket 134 and the rotating base 131 separately and then assemble and fix them.

[0058] Furthermore, please refer to the following: Figures 4 to 6In an embodiment where the number of rotating devices 13 is multiple, each rotating seat 131 is connected to a sprocket 134, and a chain 122 is wound around each sprocket 134, so that the sprocket can drive each sprocket 134 to rotate simultaneously through the chain 122, thereby driving each rotating seat 131 to rotate simultaneously.

[0059] In one optional embodiment, the drive wheel 111 is configured as a drive pulley, the transmission device 12 includes a belt, and the drive pulley is driven and connected to the belt by friction transmission. The rotating device 13 also includes a pulley, which is disposed on the rotating seat 131. The belt is wound around the drive pulley and the pulley to form a closed-loop transmission circuit, so that the drive pulley drives the belt to move, thereby driving the pulley and the rotating seat 131 to rotate synchronously. The installation method of the pulley includes, but is not limited to, the following two implementation schemes: one is to manufacture the pulley and the rotating seat 131 into a single component using an integral molding process; the other is to manufacture the pulley and the rotating seat 131 separately and then assemble and fix them.

[0060] Furthermore, in an embodiment where the number of rotating devices 13 is configured to be multiple, each rotating seat 131 is connected to a pulley, and a belt is wound around each pulley, so that the pulley can drive each pulley to rotate simultaneously through the belt, thereby driving each rotating seat 131 to rotate simultaneously.

[0061] Understandably, the drive wheel 111 receives and outputs power from the drive unit 11; the chain 122 or belt of the transmission unit 12 is used to transmit power; and the sprocket 134 or pulley of the rotating unit 13 transmits the rotational motion of the transmission unit 12 to the rotating seat 131. This transmission method has a simple structure, is easy to maintain, and is suitable for transmission requirements of various layout forms. By selecting sprockets with different numbers of teeth or pulleys with different diameters, specific transmission ratio requirements can also be achieved.

[0062] like Figure 2 , Figure 7 As shown, in some embodiments of the rotary drive mechanism 1, the transmission device 12 further includes a tensioning mechanism 121; the tensioning mechanism 121 includes a tensioning wheel 1211 and an adjusting bracket 1212, the adjusting bracket 1212 is movably mounted on the frame 2, the tensioning wheel 1211 is rotatably mounted on the adjusting bracket 1212, and the transmission device 12 is wound around the tensioning wheel 1211.

[0063] When the adjusting bracket drives the tensioning wheel 1211 to move, the tension of the transmission device 12 is adjusted through the tensioning wheel 1211.

[0064] It should be noted that the adjusting bracket 1212 is movably mounted on the frame 2 via a guide structure, and the tensioning wheel 1211 is rotatably mounted on the adjusting bracket 1212 via bearings and a pin. The chain 122 or belt of the transmission device 12 is wound around the tensioning wheel 1211. When the adjusting bracket 1212 is driven to slide along its movement trajectory by an external force, the adjusting bracket 1212 drives the tensioning wheel 1211 to move together, thereby changing the meshing position of the tensioning wheel 1211 and the transmission device 12, thus adjusting the tension of the transmission device 12.

[0065] By setting the tensioning mechanism 121, the tensioning wheel 1211 applies radial pressure to the chain 122 or belt, which can effectively compensate for the loosening or elongation deformation of the transmission device 12 caused by load and long-term use, keep the transmission system in the best tension state, eliminate transmission vibration and noise, ensure the reliability and stability of power transmission, and prevent slippage or chain derailment.

[0066] Understandably, the tensioning wheel 1211 acts as a driven wheel to apply radial pressure to the transmission device 12; the adjusting bracket 1212 is used to mount the tensioning wheel 1211 and provide guidance and support for its movement. By adjusting the movement of the bracket 1212, the tensioning wheel 1211 is displaced, thereby precisely adjusting the tension of the transmission device 12.

[0067] like Figure 3 , Figure 7 As shown, in some embodiments of the rotary drive mechanism 1, the frame 2 is provided with a tension adjustment hole 21, the adjustment bracket 1212 passes through the tension adjustment hole 21, and the adjustment bracket 1212 is configured to slide along the tension adjustment hole 21.

[0068] The tensioning mechanism 121 also includes a tensioning bolt 1213, which is screwed onto the frame 2 and the end of the tensioning bolt 1213 is movably held against the adjusting bracket 1212.

[0069] When the tension bolt 1213 rotates on the frame 2, the tension bolt 1213 moves relative to the frame 2, thereby adjusting the bracket 1212 to move along the tension adjustment hole 21 under the pressure of the tension bolt 1213.

[0070] It should be noted that when the tensioning bolt 1213 is rotated, the tensioning bolt 1213 moves axially relative to the frame 2 based on the thread transmission principle. Its end then pushes or releases the adjusting bracket 1212, forcing the adjusting bracket 1212 to slide along the tension adjustment hole 21 under the holding force, thereby driving the tensioning wheel 1211 to move, realizing fine adjustment of the tension force. The adjustment accuracy is high and the operation is simple.

[0071] Understandably, the tension adjustment hole 21 is preferably an oblong or strip-shaped hole, used to provide precise movement guidance for the adjustment bracket 1212. The cooperation between the tension adjustment hole 21 and the adjustment bracket 1212 constitutes a simple and reliable sliding guide mechanism; the tension bolt 1213 and the threaded hole on the frame 2 constitute a helical transmission mechanism, converting rotational motion into linear motion, thereby providing a precisely controllable adjustment force. This structure utilizes the self-locking characteristic of the thread, which can automatically lock the position after adjustment without the need for an additional locking device, making the tension adjustment operation both precise and convenient.

[0072] Specifically, in some embodiments of the rotary drive mechanism 1, the transmission device 12 includes a gear transmission structure that is driven and connected to the drive wheel 111, and the rotary device 13 also includes a rotary gear that is disposed on the rotary seat 131 and meshes with the gear transmission structure.

[0073] In this embodiment, the drive wheel 111 is preferably configured as a drive gear. The installation method of the rotating gear includes, but is not limited to, the following two implementation schemes: one is to manufacture the rotating gear and the rotating seat 131 into an integral part by means of an integral molding process; the other is to manufacture the rotating gear and the rotating seat 131 separately and then assemble and fix them.

[0074] Furthermore, gear drives can employ different tooth profiles, such as spur gears, helical gears, or bevel gears, to adapt to different spatial layouts and transmission requirements.

[0075] Understandably, the gear transmission structure is used to achieve a precise transmission ratio and efficient power transmission. A rotating gear meshes with the gear transmission structure to transmit power to the rotating base 131. The rotation of the drive gear drives the meshing gear transmission structure, which in turn drives the rotating gear and the rotating base 131 to rotate synchronously, ensuring that the speeds of all rotating devices 13 remain strictly synchronized, thus improving the stability and reliability of the equipment operation. At the same time, the gear transmission structure has a strong load-bearing capacity and a compact structure, making it suitable for applications requiring precise transmission and high torque output.

[0076] like Figure 5 As shown, in some embodiments of the rotary drive mechanism 1, the rotary seat 131 includes a bearing seat 1311, a bearing 1312, and a rotary shaft 1313. The bearing seat 1311 is fixedly mounted on the frame 2, and the bearing 1312 is mounted on the bearing seat 1311. The rotary shaft 1313 passes through the inner ring of the bearing 1312, and one end of the rotary shaft 1313 is driven to be connected to the transmission device 12, while the other end of the rotary shaft 1313 is connected to the connecting assembly 132.

[0077] In some embodiments, the connecting component 132 includes a hook that connects to the rotating base 131 and is used to attach the mold shell 3.

[0078] Understandably, the bearing housing 1311 is used to provide a stable support base; the bearing 1312 is used to realize the rotational connection between the rotating shaft 1313 and the bearing housing 1311. Furthermore, the setting of the bearing 1312 can make the rotation of the mold shell 3 smoother and more stable; the rotating shaft 1313 is used to connect the transmission device 12 and the connecting assembly 132, and is a key component for power transmission. The hook is used to provide the quick attachment and disassembly function of the mold shell 3, which is convenient for operation and maintenance. By setting the rotating seat 131, the stability and reliability of the rotational movement are ensured, while simplifying the installation process of the mold shell 3.

[0079] Figure 2 The present invention illustrates a drying apparatus 100 in some embodiments. The drying apparatus 100 includes a frame 2 and a rotary drive mechanism 1. The rotary drive mechanism 1 includes a drive device 11, a transmission device 12 and a plurality of rotary devices 13. The frame 2 is provided with a plurality of drying zones 22, and each drying zone 22 is provided with at least one rotary device 13. The drive device 11 and the transmission device 12 are respectively disposed on the frame 2, and the drive device 11 is driven to each rotary seat 131 through the transmission device 12.

[0080] like Figure 6 As shown, when the drive device 11 drives each rotating seat 131 to rotate through the transmission device 12, each rotating seat 131 drives each mold shell 3 to rotate.

[0081] It should be noted that the drying zones 22 can be arranged one by one in the longitudinal direction, or one by one in the transverse direction, or a combination of transverse and longitudinal extensions; the size and shape of each drying zone 22 can be customized according to the production process requirements.

[0082] The drive unit 11 of the drying equipment 100 can be flexibly configured according to production needs and spatial layout.

[0083] In one optional embodiment, the drying equipment 100 is configured in a zone-independent drive mode. Specifically, each drying zone 22 is independently equipped with a drive device 11 and a set of matching transmission devices 12. The rotating seats 131 of all rotating devices 13 within the drying zone 22 are driven and connected to this set of independent transmission devices 12. The drive end of the drive device 11 is directly driven and connected to the transmission device 12 of its respective drying zone 22.

[0084] As an exemplary implementation, when the transmission device 12 includes a chain 122 and the drive end of the drive device 11 is configured as a drive sprocket, the drive sprocket directly engages with the chain 122 of the corresponding drying zone 22.

[0085] As another exemplary implementation, when the transmission device 12 includes a belt and the drive end of the drive device 11 is configured as a drive pulley, the drive pulley is directly wound around the transmission belt of the corresponding drying zone 22.

[0086] As another exemplary implementation, when the transmission device 12 includes a gear transmission structure and the drive end of the drive device 11 is configured as a drive gear, the drive gear directly meshes with the gear transmission structure of the corresponding drying zone 22.

[0087] Thus, each drying zone 22 constitutes an independent drive unit. Operators can independently control the start, stop, speed, and direction of the drive unit 11 in any drying zone 22 without affecting the working status of other drying zones 22. This configuration allows for the simultaneous drying of mold shells 3 from different batches with different process requirements on the same equipment, greatly improving the flexibility and precision of equipment use.

[0088] In an alternative embodiment, the drying equipment 100 is configured in a centralized drive mode. Specifically, a drive unit 11 simultaneously drives multiple drying zones 22 via multiple transmission devices 12. Each drying zone 22 is provided with a corresponding set of transmission devices 12, and each set of transmission devices 12 drives all rotating seats 131 connected to the corresponding drying zone 22. The drive end of the drive unit 11 simultaneously drives these multiple sets of transmission devices 12 via a power distribution structure.

[0089] As an exemplary implementation, when the transmission device 12 includes a chain 122 and the drive wheel 111 is configured as a drive sprocket, the power distribution structure includes a main drive shaft driven by the drive device 11, and a plurality of drive sprockets are fixedly arranged on the main drive shaft, each drive sprocket meshing with the chain 122 of each drying zone 22 in a corresponding manner.

[0090] As another exemplary implementation, when the transmission device 12 includes a belt and the drive wheel 111 is configured as a drive pulley, the power distribution structure includes a main drive shaft driven by the drive device 11, and a plurality of drive pulleys are fixedly arranged on the main drive shaft, with each drive pulley corresponding to and wound around the transmission belt of each drying zone 22.

[0091] As another exemplary implementation, when the transmission device 12 includes a gear transmission structure and the drive wheel 111 is configured as a drive gear, the power distribution structure includes a main drive shaft driven by the drive device 11, a drive gear is fixedly mounted on the main drive shaft, the drive gear meshes with multiple driven gears at the same time, and each driven gear drives the gear transmission structure connected to each drying zone 22 in a one-to-one correspondence.

[0092] Therefore, a single drive unit 11 can synchronously drive all rotating devices 13 in multiple drying zones 22. This configuration unifies the power source of multiple drying zones 22, ensuring a high degree of consistency in the operating parameters of each drying zone 22. At the same time, it significantly reduces the number of drive units 11, lowers the manufacturing cost and overall energy consumption of the equipment, simplifies the control system, and is suitable for scenarios with high requirements for drying process consistency and no need for independent control.

[0093] Through the different drive configuration embodiments described above, the drying equipment 100 provided by this utility model can adapt to diverse production and process layout requirements, demonstrating good versatility and economy.

[0094] Understandably, the drying zone 22 is used to divide different drying areas to achieve zoned management. The rotary drive mechanism 1 is used to drive the mold shell 3 in each drying zone 22 to rotate. Through the zoned arrangement, different drying zones 22 can be independently controlled, improving the flexibility of the drying process and production efficiency.

[0095] like Figure 2 As shown, in some embodiments of the drying equipment 100, the drying equipment 100 includes a plurality of rotary drive mechanisms 1, each rotary drive mechanism 1 being disposed in a corresponding manner in each drying zone 22, and each drying zone 22 being provided with a plurality of rotary devices 13.

[0096] Each of the drive devices 11 is configured to drive each of the rotating seats 131 in the corresponding drying zone 22 to rotate via the transmission device 12.

[0097] Understandably, by setting multiple rotary drive mechanisms 1, the rotary drive mechanism 1 in each drying zone 22 independently drives the corresponding rotary device 13 in the drying zone 22 through the drive device 11. That is, the same drive device 11 drives each rotary seat 131 in the same drying zone 22 to rotate simultaneously through the same transmission device 12, thereby realizing independent control and refined management of each drying zone 22. Different rotary drying parameters can be set according to the process requirements of different products.

[0098] like Figure 6 , Figure 7 As shown, in some embodiments of the drying equipment 100, the drying equipment 100 further includes a plurality of blower mechanisms 4, each blower mechanism 4 being respectively disposed on the frame 2, and each blower mechanism 4 facing each mold shell 3 in a one-to-one correspondence.

[0099] It should be noted that each blower mechanism 4 of the drying equipment 100 includes a mounting base 41, a heating element 42 and a fan 43; the mounting base 41 is fixedly mounted on the frame 2, the heating element 42 and the fan 43 are respectively mounted on the mounting base 41, and a fan 43 is provided on each side of each heating element 42.

[0100] The blower mechanism 4 is arranged one-to-one with each drying zone 22. Each drying zone 22 is provided with multiple mounting seats 41, and each mounting seat 41 corresponds to the position of a mold shell 3. The heating element 42 faces the mold shell 3 and is used to generate heat to dry the mold shell 3 when it is powered on. The fan 43 is arranged one-to-one with and faces at least two surfaces of the mold shell 3 respectively, and is used to generate airflow to the mold shell 3 to dry the mold shell 3, so that the mold shell 3 in the drying zone 22 can be dried by any blower mechanism 4.

[0101] Of course, the assembly position and quantity of the heating element 42 and the fan 43 can be flexibly adjusted, depending on the product design structure and user needs, and the assembly method can be adapted accordingly.

[0102] Understandably, the blower mechanism 4 is used to provide directional hot airflow to the rotating mold shell 3. The heating element 42 is used to heat the air to provide the heat energy required for drying. The fan 43 is used to generate forced convection, which accelerates the hot air towards the surface of the mold shell 3. The directional hot airflow combined with the rotational motion of the mold shell 3 can cover the entire surface of the mold shell 3 without dead angles, which greatly accelerates the evaporation and diffusion of moisture on the surface of the mold shell 3, thereby achieving rapid and uniform drying of all surfaces of the mold shell 3 and significantly improving drying efficiency and quality.

[0103] Furthermore, such as Figure 3 As shown, the drying equipment 100 also includes a control unit 23, which is electrically connected to the drive unit 11 and the blower mechanism 4. The control unit 23 includes a control box 231 and an operating interface 232. Both the control box 231 and the operating interface 232 are fixedly mounted on the frame 2. The control box 231 houses control circuits such as a frequency converter, PLC controller, or microcontroller. The operating interface 232 is equipped with push-button switches, parameter adjustment knobs, and status indicator lights.

[0104] The control unit 23 is configured to: control the start and stop of the drive device 11 and the blower mechanism 4 in each drying zone 22 through the button switch of the operation interface 232; receive the user's adjustment command through the parameter adjustment knob to control the output speed of the drive device 11 and control the heating temperature and blowing intensity of the blower mechanism 4, thereby adjusting the rotation speed and drying time of each rotating device 13 and the mold shell 3.

[0105] Understandably, by setting up the control unit 23, centralized and precise control of the drying process is achieved. Operators can independently set the working status, rotation speed, and process parameters of each drying zone 22 according to the drying process requirements of different mold shells 3, including heating temperature, air blowing intensity, rotation speed, and working time, which greatly improves the convenience of equipment operation and process adaptability, ensures rapid response to different drying needs, and further guarantees the uniformity and consistency of the drying effect.

[0106] Specifically, the drying equipment 100 also includes a moving mechanism 24. The moving mechanism 24 includes multiple casters, each caster being fixedly mounted to the bottom of the frame 2 via a wheel frame. By providing casters, the drying equipment 100 has a moving function, facilitating adjustments to the equipment position according to production needs and improving the equipment's flexibility and site adaptability. Locking devices 241 on the casters 24 are used to fix their position during operation, ensuring operational stability and safety.
