Description

Technical Field

[0001] This utility model relates to the field of packaging container manufacturing technology, and more specifically to a film material conveying mechanism for injection molding machines used in the production of film-coated cylindrical barrels. Background Technology

[0002] In the packaging container manufacturing industry, laminated barrels (such as cosmetic packaging barrels and food containers) often require the simultaneous lamination of film materials during the injection molding process due to their surface decoration needs. These products typically employ a composite process of injection molding and film lamination, where a decorative film is pre-fixed within the injection mold, and then molten plastic is injected to bond it to the film, ultimately forming a barrel product with a patterned or functional coating on its surface.

[0003] Traditional film application involves manually placing the cylindrical container to be applied under a robotic arm. The robotic arm then places the film onto the surface of the container, where electrostatic forces cause the film to adhere. The container is then placed in a heating furnace to heat the outer wall, fixing the film to the surface. After heating, the container is removed and the next container to be applied is placed in for heating. This manual application method relies entirely on manual control for positioning accuracy, resulting in low precision and the need for repeated positioning. Consequently, the efficiency of film application is low, and the level of automation is also low, failing to meet the demands of high-efficiency production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a film material conveying mechanism for injection molding machines used in the production of film-coated cylindrical drums, which can automatically convey film material and simultaneously convey and pick up cylindrical drums, thereby improving the efficiency of film coating on cylindrical drums.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A film material conveying mechanism for an injection molding machine used to produce film-coated cylindrical drums includes a picking robot positioned next to a drum heating furnace; a crossbeam is provided between the drum heating furnace and the picking robot, and a lifting rod that moves along the crossbeam via a synchronous belt module is provided on the crossbeam; a cylindrical inner mold is provided on the side of the lifting rod facing the picking robot, and the cylindrical inner mold has several negative pressure holes for adsorbing film material, which are connected to a vacuum pump via air pipes; a picking mechanism for picking up finished cylindrical drums is provided on the outside of the lifting rod; an electrostatic discharge ring for releasing static electricity from the film material is provided on the crossbeam between the drum heating furnace and the picking robot; a finished drum conveyor belt for conveying finished drums is provided next to the drum heating furnace; the film material conveying mechanism also includes a PLC controller, the output of which is connected to the input of the picking robot, the synchronous belt module, the vacuum pump, and the picking mechanism.

[0007] To further optimize the technical solution, the picking mechanism includes a cylinder located on the outside of the lifting rod, a lifting block located at the end of the cylinder extension rod, an arc-shaped picking plate located on the lifting block via a rotating shaft, and several suction cups located on the inner side of the picking plate. The suction cups are connected to a vacuum pump via air pipes, and the input ends of the cylinder and vacuum pump rotation motors are respectively connected to the output ends of the PLC controller.

[0008] To further optimize the technical solution, a rotating motor for driving the arc-shaped pickup plate to rotate is provided on the side end of the lifting block, and the input end of the rotating motor is connected to the output end of the PLC controller.

[0009] To further optimize the technical solution, a transverse block is set on the crossbeam via a synchronous belt module, a longitudinal beam perpendicular to the crossbeam is set on the transverse block, a longitudinal block is set on the longitudinal beam via a synchronous belt module, and a lifting rod is set on the outside of the longitudinal block via a synchronous belt module. The input end of the synchronous belt module is connected to the output end of the PLC controller.

[0010] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0011] This utility model provides a film material conveying mechanism for injection molding machines used in the production of film-coated cylindrical barrels. By setting an inner film for the cylindrical barrel on a movable lifting plate, the film material is adsorbed by negative pressure and static electricity is applied to the film material, which is then moved into the cylindrical barrel heating furnace to heat and coat the outer wall of the cylindrical barrel. At the same time, the coated cylindrical barrel can also be transported out, which improves the positioning accuracy of the cylindrical barrel coating and also improves the efficiency of cylindrical barrel coating.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A film conveying mechanism for injection molding machines used in the production of film-coated drums, combined with... Figures 1 to 3 As shown, the device includes a cylindrical heating furnace 1, a picking robot 3, and a PLC controller. The cylindrical heating furnace 1 is used to fix the film material on the outer wall of the cylindrical furnace. The picking robot 3 is located next to the cylindrical heating furnace and is used to pick up the film material. The PLC controller is used to control the film material conveying. The output terminal of the PLC controller is connected to the input terminal of the cylindrical heating furnace and the picking robot respectively.

[0018] A crossbeam 2 is installed between the cylindrical heating furnace 1 and the picking robot 3. A transverse block 7 is mounted on the crossbeam 2 via a synchronous belt module 6. A longitudinal beam 8, perpendicular to the crossbeam 1, is mounted on the transverse block 7. A longitudinal block 9 is mounted on the longitudinal beam 8 via the synchronous belt module 6. A lifting rod 10 is mounted on the outer side of the longitudinal block 9 via the synchronous belt module 6. A cylindrical inner mold 16 is mounted on the lifting rod 10 facing the picking robot 3. Several negative pressure holes 17 are arranged around the cylindrical inner mold 16 to adsorb the film material. The negative pressure holes are connected to a vacuum pump via air pipes. The input terminals of the synchronous belt module and the vacuum pump are connected to the output terminal of a PLC controller. The synchronous belt module drives the cylindrical inner mold to move below the picking robot. The picking robot releases the film material, which is then adsorbed onto the surface of the cylindrical inner mold under the action of the negative pressure holes.

[0019] An electrostatic discharge ring 4 is installed on the crossbeam 2 between the cylindrical heating furnace 1 and the picking robot 3 to release static electricity from the film material. The input end of the electrostatic discharge ring is connected to the output end of the PLC controller. After the inner mold of the cylinder absorbs the film material below the picking robot, the synchronous belt module drives the inner mold of the cylinder to extend into the electrostatic discharge ring to release static electricity from the film material on the inner mold. When the synchronous belt module drives the inner mold of the cylinder to extend into the cylindrical heating furnace, the negative pressure hole on the inner mold of the cylinder no longer absorbs the film material. Under the action of static electricity, the film material is adsorbed onto the outer mold of the cylinder in the cylindrical heating furnace. The cylinder is then extended into the cylindrical heating furnace to heat the outer mold of the cylinder, so that the film material is fixed on the outer wall of the cylinder.

[0020] A picking mechanism is provided on the outer side of the lifting rod 10 to pick up the finished cylindrical barrels after film application. The picking mechanism includes a cylinder 11 located on the outer side of the lifting rod 10, a lifting block 12 at the end of the cylinder's telescopic rod, and an arc-shaped picking plate 13 mounted on the lifting block via a rotating shaft. Several suction cups 14 are provided on the inner side of the picking plate 13, and the suction cups 14 are connected to a vacuum pump via air pipes. The input terminals of the cylinder and vacuum pump's rotary motors are respectively connected to the output terminals of the PLC controller. A rotary motor 15 is provided on the side end of the lifting block 12 to drive the arc-shaped picking plate 13 to rotate. The input terminal of the rotary motor is connected to the output terminal of the PLC controller. When picking up the film-applied cylindrical barrels, the rotary motor drives the picking plate to a horizontal position with the suction cups of the picking plate facing downwards. The synchronous belt module drives the picking plate to move above the cylindrical barrel, where the negative pressure suction cups hold the barrel. The cylinder drives the cylindrical barrel to move upwards. After leaving the cylindrical barrel heating furnace, the rotary motor drives the picking plate to rotate 90°, making the cylindrical barrel vertical.

[0021] A finished product barrel conveyor belt 5 is provided on the side of the cylindrical heating furnace 1 to transport finished product barrels. The synchronous belt module drives the pickup plate to move above the finished product barrel conveyor belt. The suction cup releases the cylindrical barrel when it loses pressure and places it on the finished product barrel conveyor belt for transport.

[0022] In this invention, during the conveying of film material, a synchronous belt module drives the inner mold of the cylinder to move below the picking robot. The picking robot releases the film material, which falls onto the inner mold. Under the negative pressure of the negative pressure hole, the film material is adsorbed onto the inner mold. Then, the synchronous belt module drives the inner mold to move to the electrostatic release ring, which releases static electricity onto the film material. After the film material becomes electrostatically charged, the synchronous belt module drives the inner mold to move into the cylinder heating furnace. The negative pressure hole loses pressure, and the film material is adsorbed onto the outer mold of the cylinder inside the heating furnace under the action of static electricity. During the feeding process of the inner mold into the heating furnace, the picking plate picks up the finished cylinder behind it. During the movement of the inner mold, the cylinder on the picking plate moves outward, and the rotating motor rotates the cylinder to a vertical position. When the inner mold is adsorbing film material, it moves to the finished cylinder conveyor belt and places the finished cylinder on the finished cylinder conveyor belt for conveying. The inner mold continues to adsorb film material below the picking robot as it moves.
