[0033] like Figure 3 As shown, in order to ensure the stability of the clamping transportation, the transportation mechanism 2 also includes a fixed ring 22 and a positioning tube 24. The fixed ring 22 is installed at the bottom of the transmission plate 21, and the positioning tube 24 is clamped inside the fixed ring 22. An annular groove is opened at the top of the positioning tube 24, and a transmission ring 23 is movably clamped inside the annular groove. A plurality of hinge blocks are installed on the side wall of the transmission ring 23, and a hinge shaft 231 is movably clamped on the hinge block. As the transmission ring 23 moves, the hinge shaft 231 can be driven to move, thereby controlling the movement of the positioning shaft 241 at the bottom;

[0034] A plurality of positioning shafts 241 are hinged on the outer wall of the positioning tube 24, and the hinge shaft 231 is clamped at the top of the positioning shaft 241.

[0037] A connecting ring is installed at the bottom of the transmission shaft 25, and a plurality of compression plates 26 are clamped inside the connecting ring. The cross-section of the compression plate 26 is "V"-shaped, and a support ring 261 is installed between the bent ends at the bottom of the compression plate 26. A plurality of combing shafts 28 are installed between the movable ends of the compression plate 26. The combing shaft 28 is arc-shaped and has a plurality of friction rings on the surface. The position of the combing shaft 28 corresponds to the conveying groove 251. A plurality of buffer pressure plates 27 are installed on the outer wall of the movable end of the compression plate 26. The buffer pressure plate 27 is made of rubber and can be deformed and fit on the annular injection molded part during the clamping process to ensure buffering. The buffer pressure plate 27 can be against the surface of the injection molded part during the clamping process. While ensuring the clamping stability, it can reduce the pressure on the injection molded part and reduce the accidental situation of changes and scratches during the clamping process or the self-fragmentation under pressure.

[0038] like Figure 6As shown, in order to facilitate the subsequent packaging of the injection molded parts, a pair of fixed shafts 331 are installed on one side of the storage rack 31. The fixed shafts 331 are arc-shaped, and a clamping plate 36 is movably provided on the fixed shafts 331. The clamping plate 36 is used to limit and clamp the packaging bag. A support shaft 37 is installed at one end of the bottom of the storage rack 31. A plurality of movable baffles 371 are rotatably provided on the support shaft 37. A connecting shaft is installed between the movable baffles 371. The movable baffles 371 are used for auxiliary support.

When the injection molded part moves under the action of the cylinder, it can be kept in a horizontal state with the help of impact, and the injection molded part can also slide smoothly into the packaging bag to ensure the stability of the equipment operation.

[0039] like Figure 7 As shown, there is a situation where plastic debris is easily left on the surface of the injection molded part, and a positioning frame 32 is installed on the top of the storage rack 31. A movable frame 33 is movable on the storage rack 31. The movable frame 33 can move along the direction of the storage rack 33. A plurality of reset shafts 34 are installed between the movable frame 33 and the positioning frame 32. The other end of the reset shaft 34 is installed on the positioning frame 32, and the reset shaft 34 is elastic. With the action of external force, it can be deformed, thereby pushing the movable frame 33 to move on the storage rack 31. The reset shaft 34 is used to support the injection molded part. An elastic limiting plate is installed on the top of the reset shaft 34. A limiting groove is provided on the storage rack 31, and the elastic limiting plate is clamped between the limiting grooves. The reset shaft can be reset under the action of the elastic limiting plate.

[0040] A cleaning shaft 332 is installed at the bottom of the movable frame 33, and a plurality of separation shafts 35 are installed at the bottom of the storage frame 31. The separation shaft 35 is elastic, and the bottom of the separation shaft 35 is against the cleaning shaft 332. It is clamped between the reset shaft 34 through a connecting ring. The transmission plate 21 can reciprocate within a certain distance, so that the bottom of the injection molded part and the separation shaft 35 are squeezed, reducing the plastic fragments remaining on the injection molded part or the edge. As the reset shaft 34 is reset, the cleaning shaft 332 and the separation shaft 35 can be squeezed and rubbed against each other, so that the plastic fragments clamped on the bottom separation shaft 35 can be cleaned, reducing the situation where the plastic fragments enter the packaging bag and cause it to be scratched.

[0041] like Figure 6 As shown, a pair of cylinders are installed on the top of the packaging table 3, and the cylinder conveying end is located inside the storage rack 31, which is used to assist in pushing the injection molded parts. After the cylinder is running, the injection molded parts can be pushed outward and pushed into the packaging bag clamped on the clamping plate 36.

[0042] like Figure 2As shown, a plurality of slide grooves are provided on the storage tray 42, and a support rod 43 is movably provided inside the slide groove, and the support rod 43 is used to limit the injection molded parts. A lifting rod is installed on the top of the storage tray 42, and the lifting rod is used for auxiliary transmission of the injection molded parts. The support rod 43 can play a limiting role, and the lifting rod can push the injection molded parts upward, so as to facilitate the transfer mechanism 2 to carry out adsorption and transportation.

[0043] Working principle: First, when the injection molded parts need to be transported and packaged, the injection molded parts to be packaged can be clamped on the top of the storage tray 42, and the transfer mechanism 2 can be operated to limit the position of the annular injection molded parts, and as the transmission plate 21 moves, the injection molded parts can be transported to the inside of the storage rack 31, and the cylinder can be operated to push the injection molded parts into the packaging bag sleeved on the clamping plate 36, which is convenient for operators to pack and process. During the packaging process of the equipment, the external air pressure equipment can be operated to form a negative pressure at the bottom of the transmission shaft 25, which can adsorb the injection molded parts and clamp them inside the connecting ring, and cooperate with the compression plate 26 to play a role in preventing The blocking effect is to clamp the injection molded part at the bottom of the transmission shaft 25, and the transmission ring 23 can move, thereby driving the positioning shaft 241 at the bottom to move, and the buffer ball 242 is pressed against the bottom of the injection molded part to ensure the stability of the clamping. At this time, the external air pressure equipment can be reversed, and the injection molded part can be blown to shake off the dust and debris adsorbed on its surface. Under the action of the airflow, the bottom of the injection molded part can be driven to press against the buffer ball 242, leaving transmission space for the debris, reducing the accidental blockage during the chip removal process, and facilitating the subsequent rapid discharge of excess debris on the surface during the blowing process, thereby reducing the situation of scratching the packaging bag during the subsequent packaging process;

[0044] Then, after the debris cleaning is completed, as the transmission ring 23 moves, the positioning shaft 241 can be controlled to reset, the bottom of the transmission shaft 25 maintains a negative pressure adsorption state, and the connecting ring can be clamped between the reset shafts 34. At this time, the injection molded part can still be adsorbed on the bottom of the transmission shaft 25 under the negative pressure state, and the injection molded part can be transferred to the storage rack 31, reducing the interference between the positioning shaft 241 and the storage rack 31. The transmission plate 21 can reciprocate within a certain distance to squeeze the bottom of the injection molded part and the separation shaft 35, reducing the situation where plastic fragments remain on the injection molded part or the edge, and after the cylinder is running, the injection molded part can be pushed outward and pushed into the packaging bag clamped on the clamping plate 36.

[0045] Finally, after the injection molded parts enter the packaging bag, the operator can carry out packaging processing. As the reset shaft 34 is reset, the cleaning shaft 332 and the separation shaft 35 can be squeezed and rubbed against each other, and the plastic fragments stuck on the bottom separation shaft 35 can be cleaned to reduce the possibility of entering the packaging bag and causing it to be scratched.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
