[0016] Compared with the prior art, the present invention provides an adaptive adjustment device applied to a shuttle-type energy-saving rotational molding machine, which has the following beneficial effects:

[0017] 1. The device uses an annular sliding design of the guide plate and the support plate to allow the staff to freely adjust the spacing between the auxiliary plate and the mold box according to specific needs to adapt to molds of different sizes and shapes. This highly versatile and flexible design enables the device to better adapt to different working scenarios and process requirements, improves production efficiency and product quality.

This design not only improves work efficiency, but also facilitates maintenance work, reduces production costs and downtime.

[0019] 3. This device significantly enhances the stability of the connection between the main connecting arm and the auxiliary connecting arm through the stress plate. As a reinforcement element of the connection part, the stress plate disperses the external force or load efficiently and evenly, avoiding excessive concentration of stress in a local area, thereby effectively preventing structural fatigue and damage caused by long-term uneven force. This design not only constructs a more secure connection method, but also realizes a higher structural strength and a larger load-bearing capacity of the device, so that it can maintain excellent stability and reliability when bearing heavy loads.

[0020] 4. This device achieves a stable connection with the external rotating device through the close cooperation between the outer clamping block and the inner clamping ring of the connecting shaft.

[0034] The guide rail assembly 6 includes an inner guide rail 601, an outer guide rail 602, a guide slide 603, and a support plate 604. The inner guide rail 601 is provided at the top of the grid 5, and the outer guide rail 602 is provided on the outer side of the top of the grid 5 away from the inner guide rail 601. Guide slides 603 are provided on the inner sides of the inner guide rail 601 and the outer guide rail 602 through sliding grooves, and support plates 604 are provided on the tops of the guide slides 603. A plurality of groups of inwardly recessed positioning holes are equidistantly provided around the outer sides of the inner guide rail 601 and the outer guide rail 602.

[0035] An annular equidistant outer clamp block 201 is provided around the outer left side of the connecting shaft 2, and an inner clamp ring 202 is provided on the inner side of the outer clamp block 201. The right side of the inner clamp ring 202 is fixedly connected to the connecting shaft 2, and the outer side of the inner clamp ring 202 presents a T-shaped structure extending outward, which realizes a quick and stable connection with the mold box 9 or other connecting components, and also greatly improves work efficiency and safety. The close fit between the outer clamp block 201 and the inner clamp ring 202 ensures the stability and reliability of the connecting shaft when bearing heavy loads. At the same time, this design is also convenient for disassembly and maintenance, reducing production costs and downtime. The outer side design of the T-shaped structure of the inner clamp ring 202 not only increases the connection area and improves the stability of the connection, but also facilitates precise docking with the mold box or other connecting components. This design makes the connection process simpler and faster, reduces the complexity and time cost of manual operation, thereby improving the overall production efficiency.

[0036] The connecting seat 3 and the external ring 4 are connected by a rod body, and the rod body is located at the bottom of the grid 5. The bottom of the connecting seat 3 and the output end of the bidirectional motor 103 are fixedly connected through a coupling. This design is not only stable and reliable, but also convenient for daily maintenance and inspection, ensuring a firm connection between the connecting seat 3 and the external ring 4, and maintaining a stable connection state even under extreme working conditions. The bidirectional motor 103 is fixedly connected to the connecting seat through a coupling, ensuring the accuracy and stability of power transmission, so as to facilitate accurate adjustment of the mold box 9.

[0037] The grid 5 is a circular plate with a regular grid structure, and the grid as a whole is a regular rectangle, which improves the overall strength and stability and makes the installation and adjustment of the mold box 9 more convenient. The grid as a whole is a regular rectangle, which not only facilitates the precise positioning of the mold box 9, but also improves space utilization and mold diversity. At the same time, the structural optimization of the grid also reduces production costs and processing difficulty, and improves production efficiency.

[0038] Both sides of the top of the support plate 604 are provided with inwardly recessed mounting holes, and the interior of the mounting holes adopts a threaded structure, and the top of the support plate 604 is respectively provided with an auxiliary connecting plate 7 and a mold box 9 through preset mounting holes. The auxiliary connecting plate 7 and the mold box 9 are staggered for installation, which is convenient for the fixed installation of the auxiliary connecting plate and the mold box, and also improves the accuracy and stability of the installation. The auxiliary connecting plate 7 and the mold box 9 are staggered for installation. This installation method not only improves the space utilization rate, but also enables the mold box 9 to be flexibly adjusted at different positions, and at the same time, improves the production efficiency. By adjusting the relative position of the auxiliary connecting plate 7 and the mold box 9, it can easily adapt to molds of different sizes and shapes to meet diverse production needs. This flexibility not only improves the adaptability of the production line, but also reduces the downtime and adjustment cost when changing the mold. It not only improves the accuracy and stability of the installation, but also enhances the flexibility and adaptability of the production line, reduces the production cost and processing difficulty, and improves the production efficiency.

[0039] A fixing seat 8 is provided at both ends of the top of the auxiliary connecting plate 7. An inwardly recessed hexagonal groove is provided on the top of the fixing seat 8, and an inwardly recessed mounting hole is provided inside the groove. A threaded structure is adopted inside the mounting hole, which is convenient for quick connection and fixation with other components, and also improves the accuracy and stability of the connection. The hexagonal structure is easy to rotate with tools such as wrenches, so the disassembly and reinstallation of the fixing seat 8 becomes simpler and faster. The design of the hexagonal groove makes the fixing seat 8 more stable and reliable when bearing heavy loads, avoiding production accidents caused by loose connections. At the same time, this design is also convenient for disassembly and maintenance, reducing production costs and downtime.

[0040] Both sides of the mold box 9 are provided with inner grooves 10, and push plates 11 are provided inside the inner grooves 10 through the slide grooves. The inner grooves 10 are provided with through holes. The top sides of the mold box 9 are provided with inwardly recessed sealing grooves 12, and the sealing grooves 12 are overall inverted trapezoidal structures. The top of the mold box 9 is provided with a top cover 13, which is convenient for placing and adjusting the mold, and also improves the speed and flexibility of mold replacement. The design of the inner groove enables the mold to be stably placed in the mold box, avoiding production accidents caused by mold shaking. The design of the push plate 11 enables the worker to quickly install and adjust the mold box 9 and the top cover 13. The disassembly of the mold box 9 improves the production efficiency. At the same time, the design of the through hole provides convenient conditions for the movement of the push plate, making the adjustment of the mold more precise and efficient. The operator can easily place, adjust or replace the mold without disassembling the entire mold box 9, which also reduces labor intensity and improves work efficiency. The presence of the sealing groove 12 effectively prevents the interaction between the inside of the mold box and the external environment, and avoids the influence of impurities such as dust and moisture on the mold and the production process. At the same time, the design of the inverted trapezoidal structure enables the top cover to fit the mold box more closely when closed, further improving the sealing effect.

[0041] A cylindrical protrusion is provided on the inner side of the push plate 11, and the protrusion is adapted to the through hole inside the inner groove 10, ensuring the stability and accuracy of the push plate 11 during movement, and avoiding damage to the mold caused by the shaking of the push plate. The close fit between the cylindrical protrusion and the through hole enables the push plate to move the mold smoothly without any deviation or shaking. At the same time, this design also reduces production costs and processing difficulty and improves production efficiency.

[0042] The top cover 13 is provided with connecting plates 14 on both sides of the bottom, and cylindrical grooves that are concave inward are provided on both sides of the inner part of the connecting plate 14, and spring members 15 are provided inside the cylindrical grooves, and a clamping rod 16 is provided at one end of the spring member 15. Sealing pads 17 are provided at both ends of the bottom of the top cover 13. The sealing pad 17 is an inverted trapezoidal structure as a whole, and the sealing pad 17 can be tightly fitted with the sealing groove 12, thereby achieving a tight connection and fixation with the mold box 9. The design of the connecting plate 14 enables the top cover 13 to be firmly installed on the mold box 9 to avoid material leakage caused by loosening of the top cover 13. The design of the spring member 15 and the clamping rod 16 enables the top cover to automatically adjust its position when subjected to external force to maintain a close fit with the mold box, thereby effectively preventing material leakage during rotational molding, thereby improving product quality and production efficiency. Secondly, it is convenient for staff to quickly separate the top cover 13 from the mold box 9. At the same time, this design is also convenient for disassembly and maintenance, reducing production costs and downtime.

[0043] The clamping rod 16 is cut obliquely from the center line of one end, and the section formed is an ellipse. The complete cylindrical part and the wedge-shaped part formed by the section make the clamping rod 16 smoother when inserted and removed, reduce friction and resistance, and improve the stability and firmness of the connection between the clamping rod 16 and the mold box 9. The elliptical section design enables the clamping rod 16 to automatically adjust its direction to adapt to the mold 9 when inserted, and avoids the problem of loose connection caused by deviation of the mounting hole. At the same time, the complete cylindrical part and the wedge-shaped part formed by the section further enhance the connection strength between the clamping rod 16 and the mold box 9, making the entire device more stable and reliable when bearing heavy loads.

[0044] Working principle: First, the connecting shaft 2 is fully engaged with the external rotating device connection structure through the cooperation of the external engaging block 201 and the internal engaging ring 202. This engaging method can not only provide a more secure connection, reduce the risk of loosening or slipping of the connecting shaft 2 during rotation, and ensure the overall stability of the device, but also effectively transmit torque, so that the power of the external rotating device is smoothly transmitted to the connecting shaft 2, thereby ensuring the normal operation of the mold adaptive adjustment device. During the rotation process, the full engagement can also prevent the connecting shaft 2 from sliding relative to or disengaging from the external structure, further ensuring the safety and stability of the device. At the same time, the rotation of the connecting shaft 2 will drive the entire device to rotate. At this time, the stress plate 101 can be used to adjust the main connecting arm 1 is fixed to the connection part with the auxiliary connecting arm 102, and the external force or load on it is dispersed, so that these forces can be dispersed to a larger area, reducing local stress concentration, helping to prevent excessive deformation of key components such as the main connecting arm 1, and maintaining the shape and dimensional stability of the device. In addition, the increased overall structural strength of the device enables it to withstand greater force and pressure, thereby improving the durability and reliability of the device. When the mold needs to be replaced or maintained, the staff can push the push plate 11 inward to make it move horizontally. During the horizontal movement of the push plate 11, its cylindrical protrusion will squeeze the clamping rod 16 inward. After being squeezed, the clamping rod 16 will move inward horizontally and squeeze the spring member 15. When one end of the clamping rod 16 moves to the connecting plate 14 When the internal hole is in a horizontal position, the staff can quickly separate the top cover 13 from the mold box 9. This design not only improves work efficiency, but also facilitates maintenance work. At the same time, it increases production flexibility and ensures the safety of operation. The staff can also fix and install different molds through the cooperation of the auxiliary connecting plate 7 and the fixing seat 8. This design can adapt to molds of different types and sizes, increasing the versatility and flexibility of the device. In this way, the production downtime caused by mold replacement and installation can be reduced, and the continuity and efficiency of production can be improved. After the mold is installed, the staff can drive the auxiliary connecting plate 7 and the mold box 9 on the inner guide rail 601 and the outer guide rail 602 through the cooperation of the guide slide plate 603 and the support plate 604. The inner side performs circular sliding. This function allows the staff to freely adjust the spacing distance between the auxiliary connecting plate 7 and the mold box 9 according to specific needs, which means that it can adapt to molds of different sizes and shapes, increasing the versatility of the device. Secondly, the staff can achieve the required spacing by fine-tuning the position of the guide plate 603 and the support plate 604 to ensure more accurate installation and operation of the mold. In addition, according to different mold sizes and work requirements, adjusting the spacing distance can optimize the use of the working space, better arrange and arrange the molds, and improve the neatness and organization of the working area. Accurate mold installation and appropriate spacing distance help improve production quality, ensure the stability and accuracy of the mold, thereby improving the consistency and precision of the product. Finally,The operation of the bidirectional motor 103 can drive the connection seat 3 and the overall structure to rotate bidirectionally. This function enables the mold to be better heated and the material to be better attached to the inside of the mold. The bidirectional rotation increases the flexibility and diversity of the operation, allowing the device to better adapt to different working scenes and process requirements. In general, the device provides a more secure connection, higher structural strength, more convenient operation and maintenance, better versatility and flexibility, and higher production efficiency and quality through the connection of the connecting shaft 2 with the external rotating device, the fixation and dispersion of external force of the connection part by the stress plate 101, the cooperation of the push plate 11 and the clamping rod 16 to achieve rapid separation, the fixed installation of different molds by the auxiliary connecting plate 7 and the fixed seat 8, the cooperation of the guide plate 603 and the support plate 604 to adjust the spacing distance, and the bidirectional motor 103 to drive the overall structure to rotate bidirectionally.
