Description

Technical Field

[0001] This application relates to the field of film manufacturing technology, and more specifically, to a high-efficiency injection molding film forming machine. Background Technology

[0002] With the rapid development of the manufacturing industry, production efficiency has become a key factor restricting the development of the plastics processing industry. Currently, while traditional injection molding technology meets basic needs to a certain extent in plastic film production, it still suffers from low production efficiency. For example, existing injection molding machines suffer from long injection cycles and high defect rates due to unreasonable machine design and slow material dissolution. These problems are particularly prominent in large-scale, high-precision film molding production, severely limiting its widespread application in high-end plastic packaging, electronic component protection, and other fields. Therefore, there is a need to develop a high-efficiency injection molding film molding machine. Utility Model Content

[0003] This application provides a high-efficiency injection molding film forming machine, including a feed barrel, a screw, a pusher barrel, and a reciprocating power mechanism. The feed barrel has a feed inlet, and the screw is coaxially mounted inside the feed barrel. The pusher barrel is located inside the feed barrel and is sleeved around the outer periphery of the screw. The reciprocating power mechanism is connected to the pusher barrel and is used to drive the pusher barrel to reciprocate along the axial direction of the screw, so that the pusher barrel can push the feed material in the feed inlet towards the discharge direction.

[0004] In some embodiments, the feed cylinder includes a first inner cylinder and a second inner cylinder connected axially, the second inner cylinder gradually tapering from one end near the first inner cylinder to the other end, the first inner cylinder being used to accommodate the feed cylinder, and the second inner cylinder being used to extrude feed.

[0007] In some embodiments, a protruding ring is formed on the feed cylinder, and an elastic element is provided between the protruding ring and the end face of the outer cylinder of the feeder cylinder. The elastic element is used to support the protruding ring so that the feed cylinder can spring back.

[0008] In some embodiments, a limiting element is provided between the propulsion cylinder and the feed cylinder to prevent the propulsion cylinder from rotating.

[0023] Please see Figure 1 This application provides a high-efficiency injection molding film forming machine 100, including a feed barrel 10, a screw 20, a pusher cylinder 30, and a reciprocating power mechanism 40. The feed barrel 10 is provided with a feed inlet 11. The screw 20 is coaxially installed inside the feed barrel 10. The pusher cylinder 30 is located inside the feed barrel 10 and is sleeved on the outer periphery of the screw 20. The reciprocating power mechanism 40 is connected to the pusher cylinder 30 and is used to push the pusher cylinder 30 to reciprocate along the axial direction of the screw 20, so that the pusher cylinder 30 can push the feed material in the feed inlet 11 to move in the discharge direction.

[0024] The film molding machine 100 of this application adopts an innovative design that uses a reciprocating power mechanism 40 to drive the feed cylinder 30 to reciprocate along the screw 20 axis. This enables rapid and continuous material propulsion within the feed cylinder 10, significantly improving injection speed and production efficiency, and effectively solving the problems of low injection efficiency and insufficient material utilization in traditional injection molding machines. This design not only greatly reduces energy consumption and raw material waste during the production process, but also significantly shortens the injection cycle and improves the overall flexibility of the production line.

[0025] Specifically, please refer to Figure 1 and Figure 2The film forming machine 100 mainly includes a feeding cylinder 10 and an extrusion cylinder 50, which are connected. The feeding cylinder 10 includes a first inner cylinder 12 and a second inner cylinder 13 connected together. The first inner cylinder 12 is used to accommodate the feed cylinder 30, and the second inner cylinder 13 is used for extrusion feeding. The second inner cylinder 13 gradually tapers from one end near the first inner cylinder to the other end. Then, the smaller end of the second inner cylinder 13 is connected to the extrusion cylinder 50. Multiple heating devices 51 are provided on the outside of the extrusion cylinder 50 for heating and dissolving the material into a glue. A discharge nozzle 52 is provided on the outside of the extrusion cylinder 50, and the nozzle 52 is connected to the forming mold (not shown). The screw 20 is connected to a drive device (not shown), and the drive device drives the screw 20 to rotate.

[0026] A limiting member 14 is provided on one end face of the feed cylinder 10 to restrict the radial rotation of the feed cylinder 30. In the embodiment of this application, a cylinder protrudes from one end face of the feed cylinder 10 to form the limiting member 14. A feed hopper 15 for receiving material is provided on the feed cylinder 10. During feeding, the design of the second inner cylinder 13 gradually narrowing can increase the feeding area and allow the material to smoothly enter the extrusion cylinder 50.

[0027] Please see Figure 3 The screw 20 is coaxially mounted inside the feed barrel 10. One end of the screw 20 protrudes from one end face of the feed barrel 10, while the other end face extends into the extrusion barrel 50. The inner diameter of the screw 20 gradually increases along the discharge direction, which significantly increases the extrusion volume. An extension 21 is provided on the screw 20 at a position corresponding to the feed port 11, from which the threads on the screw 20 extend in the discharge direction. During feeding, the extension 21 helps to guide the material into the pitch of the threads.

[0028] Please combine Figures 2 to 4 One end of the feed cylinder 30 extending out of the feed cylinder 10 has a wavy protrusion 31 along the axial direction. The other end of the feed cylinder 30 is a circular straight cylinder, used to push material from the first inner cylinder 12 into the second inner cylinder 13 and the extruder cylinder 50. One end of the feed cylinder 30 has a convex ring 32, and a recess 33 is formed on the convex ring 32 corresponding to the limiting member 14. When the feed cylinder 30 is installed inside the feed cylinder 10, the limiting member 14 can extend into the recess 33, thereby restricting the radial rotation of the feed cylinder 30. In the embodiment of this application, the recess 33 is a circular notch corresponding to the curved surface of the cylinder.

[0029] An elastic element 34 is provided between the convex ring 32 and the end face of the outer cylinder of the feed cylinder 10. The elastic element 34 is used to support the convex ring 32 so that the feed cylinder 30 can rebound. In the embodiment of this application, the elastic element 34 is a spring, which is sleeved on the outer periphery of the feed cylinder 30, and its two ends abut against the end faces of the convex ring 32 and the feed cylinder 10, respectively.

[0030] Please see Figure 1 and Figure 2 The reciprocating power mechanism 40 includes a collar 41 fixedly sleeved on the screw 20. The collar 41 has a notch 42 corresponding to the protrusion 31 in the axial direction. The screw 20 drives the notch 42 to rotate, and the notch 42 and the protrusion 31 cooperate to form a cam mechanism, causing the propulsion cylinder 30 to perform reciprocating motion. In other embodiments, other reciprocating power mechanisms 40 can also be used to realize the reciprocating motion of the propulsion cylinder 30, such as an eccentric reciprocating mechanism.

[0031] When the film forming machine 100 is working, the material enters the feed cylinder 10 through the feed hopper 15. The screw 20 rotates, driving the collar 41 to rotate. The notch 42 on the collar 41 engages with the protrusion 31 of the push cylinder 30. Under the action of the elastic element 34, the push cylinder 30 can reciprocate along the screw 20. The other end of the push cylinder 30 pushes the material towards the extrusion cylinder, thereby increasing the amount of material entering and improving the working efficiency of the film forming machine 100.
