Description

Technical Field

[0001] The present invention relates to a dispenser, and in particular to a combined micro-laminated dispenser with a superposition multiplication function. Background Art

[0002] At present, many thin film products require the compounding of multiple layers of raw materials to improve the barrier properties and physical properties of the thin film. The thin film belongs to a multi-layer co-extrusion compound product. During the compounding process, it is required to uniformly compound different raw materials together. Currently, the existing dispensers can only achieve uniform compounding of several layers or more than a dozen layers, and it is very difficult to achieve uniform compounding of dozens of layers or hundreds of layers. Summary of the Invention

[0003] In view of the above problems, the present invention aims to provide a combined micro-laminated dispenser with a superposition multiplication function, which has a novel structure and can achieve uniform compounding of dozens or even hundreds of layers of different raw materials of the product by increasing the number of flow channels.

[0004] The technical solution of the present invention is a combined micro-laminated dispenser, which includes a first feed plate, a first flow dividing plate, a compounding plate, a second flow dividing plate and a second feed plate connected in sequence. A raw material compounding area is arranged in the middle of the compounding plate, and a discharge channel connected to the raw material compounding area is arranged on the side of the compounding plate. A first feed port is arranged on the outer end face of the first feed plate, and a first main flow channel area is arranged on the inner end face of the first feed plate. A plurality of first branch channels along the axial direction are arranged on the first flow dividing plate at equal angles on the same circumference facing the first main flow channel area. A second feed port is arranged on the outer end face of the second feed plate, and a second main flow channel area is arranged on the inner end face of the second feed plate. A plurality of second branch channels along the axial direction are arranged on the second flow dividing plate at equal angles on the same circumference facing the second main flow channel area. A plurality of flow dividing channels are arranged on the compounding plate along the radial direction. The outer ends of the even-numbered flow dividing channels in the clockwise direction are correspondingly connected to the second branch channels one by one, and the outer ends of the odd-numbered flow dividing channels in the clockwise direction are correspondingly connected to the first branch channels one by one. The inner ends of all the flow dividing channels are located on the same circumference and are connected to the raw material compounding area. The compounded raw materials are extruded through the discharge channel.

[0005] Preferably, both the first main runner area and the second main runner area are fan-shaped concave groove structures. After the first feeding plate and the first flow dividing plate are connected, the first branch runner is located in the fan-shaped concave groove of the first main runner area. After the raw material flows in from the first feeding port, it diffuses through the fan-shaped concave groove and evenly flows into each first branch runner, and then enters the odd-numbered flow dividing runners on the composite plate in the clockwise direction; after the second feeding plate and the second flow dividing plate are connected, the second branch runner is located in the fan-shaped concave groove of the second main runner area. After the raw material flows in from the second feeding port, it diffuses through the fan-shaped concave groove and evenly flows into each second branch runner, and then enters the even-numbered flow dividing runners on the composite plate in the clockwise direction.

[0006] Preferably, the discharge channel is located at the front end of the raw material composite area and penetrates through the front side of the composite plate, and the flow dividing runners are arranged on the left side, right side and rear side of the raw material composite area and are arranged in a fan-shaped divergence.

[0007] Preferably, an arc section is provided for transition between the flow dividing runner located on the outermost edge side of the composite plate and the discharge channel.

[0008] The present invention can achieve uniform compounding of dozens or even hundreds of layers of different raw materials of the product by increasing the number of the first branch runners, the second branch runners and the flow dividing runners. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of axial first branch flow channels 10 arranged at equal angles on the same circumference are provided on the first diverter plate 2 facing the first main flow channel area 9. A second feed port 11 is provided on the outer end face of the second feed plate 5. A second main flow channel area 12 is provided on the inner end face of the second feed plate 5. A plurality of axial second branch flow channels 13 arranged at equal angles on the same circumference are provided on the second diverter plate 4 facing the second main flow channel area 12. A plurality of diverter flow channels 14 are provided on the composite plate 3 along the radial direction. The outer ends of the even-numbered diverter flow channels 14 in the clockwise direction are correspondingly connected to the second branch flow channels 13 one by one. The outer ends of the odd-numbered diverter flow channels 14 in the clockwise direction are correspondingly connected to the first branch flow channels 10 one by one. The inner ends of all the diverter flow channels 14 are located on the same circumference and are connected to the raw material composite area 6. The compounded raw materials are extruded through the discharge channel 7.

[0022] Preferably, both the first main runner area 9 and the second main runner area 12 are fan-shaped recessed groove structures. After the first feeding plate 1 and the first flow dividing plate 2 are connected, the first branch runner 10 is located in the fan-shaped recessed groove of the first main runner area 9. After the raw material flows in from the first feeding port 8, it diffuses through the fan-shaped recessed groove and then evenly flows into each first branch runner 10, and enters the odd-numbered flow dividing runners 14 on the composite plate 3 in the clockwise direction; after the second feeding plate 5 and the second flow dividing plate 4 are connected, the second branch runner 13 is located in the fan-shaped recessed groove of the second main runner area 12. After the raw material flows in from the second feeding port 11, it diffuses through the fan-shaped recessed groove and then evenly flows into each second branch runner 13, and enters the even-numbered flow dividing runners 14 on the composite plate 3 in the clockwise direction.

[0023] Preferably, the discharge channel 7 is located at the front end of the raw material composite area 6 and penetrates the front side of the composite plate 3, and the flow dividing runners 14 are arranged on the left side, right side and rear side of the raw material composite area 6 and are arranged in a fan-shaped divergence.
