Description

Technical Field

[0001] This utility model relates to the field of plastic cup production technology, and in particular to a material feeding structure for an injection molding machine used in the production of plastic cups that facilitates material receiving. Background Technology

[0002] Plastic cup manufacturers often need to use injection molding machines to produce plastic cups. In order to facilitate the collection and transfer of plastic cups by workers, it is usually necessary to use robotic arms and suction cylinders installed in conjunction with the mold to pick up the plastic cups ejected by the ejection mechanism and then transfer them to the external worktable of the injection molding machine under the action of the robotic arms for stacking. The stacked plastic cups are then packaged and transferred.

[0003] A material feeding structure for an injection molding machine used in the production of disposable plastic cups, disclosed in Chinese Patent Publication No. CN221697688U, includes a conveyor belt with a receiving plate at one end and a receiving bucket at the bottom of the receiving plate. A limiting seat is installed at the bottom of the receiving bucket, and a conveyor belt is connected to the bottom of the limiting seat. A first positioning plate and a second positioning plate are symmetrically installed inside the limiting seat. A screw is installed at the end of the limiting seat near the first positioning plate. A telescopic cylinder is installed at the end of the limiting seat near the second positioning plate. A telescopic column is slidably connected inside the telescopic cylinder, with one end of the telescopic column mounted on the second positioning plate and a spring sleeved on the outside of the telescopic column.

[0004] In the above-mentioned device, the plastic cups are transported into the receiving bin and then conveyed by the conveyor belt to the next place for discharge. Because the plastic cups are inside the receiving bin, the subsequent discharge is inconvenient and increases the discharge time.

The material feeding structure of an injection molding machine for producing plastic cups with convenient material receiving includes: a cylinder 1, with several sets of support columns 2 installed at the bottom of the cylinder 1; an annular block 13 installed at the bottom inside the cylinder 1, with a groove at the top of the annular block 13; a cylinder 4 in contact with the top of the annular block 13; several sets of arc-shaped grooves 5 evenly distributed at the top of the cylinder 4, each set of arc-shaped grooves 5 penetrating the side wall of the cylinder 4; a circular cover 11 installed at the bottom of the cylinder 1; and a motor 10 installed at the bottom inside the circular cover 11. The output end of the second motor 10 extends into the inside of the cylinder 1, and the output end of the second motor 10 is fixedly connected to the bottom of the cylinder 4. A pushing assembly 6 is installed between the inside of the cylinder 4 and the inner wall of the arc groove 5. Two sets of guide plates 7 are installed on the right outer wall of the cylinder 1. The guide plates 7 are connected to the cylinder 1. A conveying assembly 8 is installed between the lower inner walls of the two sets of guide plates 7. One end of the conveying assembly 8 is located directly below the arc groove 5. A feeding pipe 3 is installed directly above one set of the arc groove 5. The other end of the feeding pipe 3 is connected to a discharge device.

[0024] The feeding assembly 6 includes a circular groove 61. Several sets of circular grooves 61 are evenly opened inside the cylinder 4. Each set of circular grooves 61 is connected to each set of arc grooves 5. An electric push rod 62 is installed on the inner wall of each set of circular grooves 61. The output end of each set of electric push rods 62 extends into the arc groove 5, and a push plate 63 is installed on the output end of the electric push rod 62. When the arc groove 5 moves the plastic cup to the guide plate 7, the output end of the electric push rod 62 pushes the plastic cup into the conveying assembly 8 through the push plate 63.

[0025] The conveying assembly 8 includes a motor 81, which is fixedly installed on the front outer wall of the guide plate 7. The output end of the motor 81 passes through the guide plate 7 and is connected to a drive shaft 83.

[0028] The outer wall of the circular cover 11 is provided with several sets of heat dissipation holes 12. The heat dissipation holes 12 facilitate the discharge of the high temperature generated by the motor 10 from the circular cover 11.

[0029] The working principle of the convenient material receiving structure for injection molding machines used in the production of plastic cups provided by this utility model is as follows: After the plastic cups produced by the feeding pipe 3 are automatically fed into a set of arc-shaped grooves 5, the output end of the motor 10 drives the cylinder 4 to rotate, turning the arc-shaped grooves 5 filled with plastic cups away from the bottom of the feeding pipe 3, while another set of arc-shaped grooves 5 come to the bottom of the feeding pipe 3 for feeding. When the arc-shaped grooves 5 filled with plastic cups move to the inlet end of the guide plate 7, the pushing component 6 will push the plastic cups from the inside of the arc-shaped grooves 5 onto the conveying component 8. Under the restriction of the guide plate 7, the conveying component 8 transports the plastic cups to the next station.

[0030] Compared with related technologies, the convenient material receiving structure for injection molding machines used in the production of plastic cups provided by this utility model has the following beneficial effects:

[0031] Through the interaction of components such as the feeding pipe 3, the arc-shaped groove 5, the motor 10, the cylinder 4, the guide plate 7, the pushing assembly 6, and the conveying assembly 8, the produced plastic cups can be automatically and orderly fed out and transported to the next station for processing.
