[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Reference Figs. 1-3 As shown in the figure, a color mold feeding and discharging mechanism, including a material cylinder assembly 11 for placing the color mold, a transplanting assembly 13 for taking and placing the color mold, and a receiving and transferring assembly 12 for adjusting the feeding height of the color mold; the material cylinder assembly 11 includes a rotating material cylinder 112, a material cylinder drive 111 for driving the rotating material cylinder 112 to rotate, a pushing rod 114 for pushing the color mold inside the rotating material cylinder 112, and a push rod module 113 for driving the pushing rod 114 to lift;

[0023] In the feeding action, the push rod module 113 drives the pushing rod 114 to extend into the rotating material cylinder 112, pushes the color mold to the specified position, the transplanting assembly 13 adsorbs the color mold and places it on the receiving and transferring assembly 12, and the receiving and transferring assembly 12 suspends the color mold at the specified height, waiting for the subsequent action; in the discharging action, the external assembly places the color mold on the receiving and transferring assembly 12, the receiving and transferring assembly 12 lifts the color mold to the working position of the transplanting assembly 13, the transplanting assembly 13 adsorbs the color mold and places it in the rotating material cylinder 112, and the push rod module 113 drives the pushing rod 114 to push against the color mold and gradually descend.

[0024] In practical use, this utility model can be freely selected for loading or unloading according to layout requirements. During the loading operation, the rotating material cylinder 112 serves as a temporary storage unit for the colored molds. The push rod module 113 is a linear motor used to drive the push rod 114 to extend into the rotating material cylinder 112, which can push the colored molds inside the rotating material cylinder 112 to rise, so that the uppermost colored mold is always located in the suction and transportation position of the transfer component 13. After the transportation component 13 picks up the colored mold from the rotating material cylinder 112, it is transported to the receiving and transfer component 12, which then moves the colored mold to an external production line or other turnover location. The components are matched in height; the overall feeding efficiency is improved, and the feeding stage can be adapted to various types of equipment layouts; during the unloading action, the overall process is that the color mold is collected into the rotating material cylinder 112. After the external production line or other turnover components place the color mold on the receiving and transfer component 12, the receiving and transfer component 12 moves the color mold to the working position height of the handling component 13. The handling component 13 then transports the color mold into the rotating material cylinder 112. During the color mold collection process, the push rod module 113 drives the push rod 114 to gradually descend, reserving placement space for each color mold that is about to be collected.

[0025] The loading and unloading mechanism of this optical mold has a simplified overall structure and can be functionally differentiated as needed to meet the requirements of loading and unloading operations. The cylindrical temporary storage of materials makes reasonable use of longitudinal space, reduces the equipment's footprint, and improves the overall efficiency of loading and unloading operations. In addition, it is equipped with a height adjustment structure to meet and adapt to various types of material conveying structures, thereby improving the overall adaptability of the loading and unloading mechanism.

[0026] In this embodiment, the rotating material cylinder 112 includes several material cylinder groups 1121, the bottom of which is mounted on a rotating base plate 1122. The material cylinder drive 111 drives the rotating base plate 1122 to rotate. This application adopts a double material cylinder group 1121 design, which is centrally symmetrically mounted on the rotating base plate 1122. When the colored mold in one material cylinder group 1121 is completely conveyed or the storage is full, the material cylinder drive 111 rotates the rotating base plate 1122 to rotate the other rotating material cylinder group 1121 back to the working position of the conveying structure 13, realizing the backup and use of the material cylinder group 1121. The material cylinder group 1121 can be adjusted in multiple groups according to the actual operation situation, thereby improving the capacity release of one-time loading and unloading and the adjustment of product storage capacity.

[0027] In this embodiment, the rotating base plate 1122 has a push rod through hole 1123 at the bottom of the material cylinder assembly 1121 to facilitate the push rod 114 to extend into the material cylinder assembly 1121. The diameter of the push rod through hole 1123 is smaller than the diameter of the color mold. The height of the material cylinder assembly 1121 matches the installation height of the transfer component 13. The push rod 114 enters the material cylinder assembly 1121 through the push rod through hole 1123. The color mold can be smoothly stored or removed in the material cylinder assembly 1121, which matches its size. The diameter of the push rod through hole 1123 is smaller than that of the color mold to prevent the color mold from falling out of the material cylinder assembly 1121. The push rod 114 is driven by the push rod module 113 to push the color mold up and down to meet the different height changes of the color mold material during the loading and unloading process.

[0028] In this embodiment, the transplanting assembly 13 includes a color mold suction cup 135, a material handling frame plate 132 for assembling the color mold suction cup 135, and a material handling drive 131 for driving the material handling frame plate 132. The color mold suction cup 135 is connected to the material handling frame plate 132 via a material handling guide rod 134. In this embodiment, the material handling frame plate 132 is also equipped with a suction cup push cylinder 133 for pushing the color mold suction cup 135 downward. The telescopic end of the suction cup push cylinder 133 passes through the material handling frame plate 132 and is connected to the color mold suction cup 135. The color mold suction cup 135 is connected to an external air source. The color mold suction cup 135 is a multi-head suction cup, connected to an external air source to adsorb the color mold. The suction cup push cylinder 133 is used to control the downward height of the color mold suction cup 135. The material handling guide rod 134 ensures that the color mold suction cup 135 can slide smoothly with the material handling frame plate 132, so as to ensure that the color mold suction cup 135 can completely adsorb the color mold.

[0029] In this embodiment, the material handling drive 131 is supported and installed by a material handling frame 136, and the transfer assembly 12 is installed on the material handling frame 136. In this embodiment, the transfer assembly 12 includes a height adjustment frame 121 for temporarily storing colored molds and a height adaptation drive 122 for driving the height adjustment frame 121 to rise and fall. The height adjustment frame 121 is installed on the moving end of the height adaptation drive 122, and the placement hole of the height adjustment frame 121 corresponds to the colored mold suction cup 135. The height adaptation drive 122 is a linear motor module installed on the material handling frame 126 and is used to drive the height adjustment frame 121 to rise and fall. The height adjustment frame 121 is movably installed on the moving end of the height adaptation drive 122 and can be quickly replaced as needed according to the colored mold suction cup 135 or the rear conveying equipment. This ensures that the colored mold can be quickly turned over between the handling assembly 13 and the conveying equipment. The transfer assembly 12 can adapt to more equipment layout types and various heights and sizes of conveying equipment.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
