Description

TECHNICAL FIELD

[0001] The present application relates to an extrusion die distributor, in particular to a color strip solar film co-extrusion distributor. BACKGROUND

[0002] The production of color strip solar film is intended to achieve special physical properties of the film. Currently, color strip solar film is mainly realized by die plus combiner. The structure is complex, the cost is high, and the function is single. Only fixed width ratio of solar film can be extruded. When the width ratio of multiple raw materials in the film changes greatly or the product needs to be produced by stacking up and down, a new whole die set must be replaced to meet the production needs, resulting in high use cost.

[0003] The conventional distributor realizes the up and down composite of the raw materials, and it is difficult to realize the uniform composite in the width direction. SUMMARY

[0004] In view of the above problems, the present application aims to provide a color strip solar film co-extrusion distributor, which has a novel structure and can realize the composite of different materials of color strip solar film in the width direction, and cooperate with the conventional single-layer extrusion die to realize the normal extrusion of color strip solar film.

[0005] The technical scheme of the present application is a color strip solar film co-extrusion distributor, which comprises a main body one, a main body two, a flow dividing insert and a discharge plate arranged from top to bottom. A B material inlet is arranged on the main body one. An A material inlet is arranged on the side surface of the main body two. A B material channel is vertically arranged in the middle of the main body two and penetrates the upper and lower surfaces thereof. A composite channel is arranged in the middle of the flow dividing insert corresponding to the B material channel. An A material flow channel is arranged on the main body two and extends to the left and right sides and then penetrates the main body two downward. An A material flow dividing channel is arranged on the upper surface of the flow dividing insert and located on the left and right sides of the composite channel. The A material flow dividing channel is divided in the flow dividing insert and then gathered in the width direction on the left and right sides of the composite channel. A discharge port is arranged on the discharge plate corresponding to the bottom of the composite channel. The A material and the B material are combined through the composite channel to form an ABA structure of the raw material which is extruded from the discharge port.

[0006] Preferably, the A-material diversion channel includes a horizontal section and a vertical section. The horizontal section extends smoothly from the outside to the inside and back to both sides of the composite channel. When it reaches the front and back positions of the composite channel, it enters the vertical section. A conical diversion block with a larger top and a smaller bottom is provided on the top surface of the vertical section for guiding the flow. A conical baffle with a larger top and a smaller bottom is provided between the upper part of the vertical section and the composite channel. The bottom end of the conical baffle terminates at the lower part of the vertical section. The A-material contacts and combines with the B-material in the composite channel at the lower part of the vertical section to form a composite raw material with an ABA structure in the width direction.

[0007] Preferably, the A material inlet and A material flow channel are located at the junction of main body one and main body two. Half of the inlet and the flow channel are respectively opened on the bottom surface of main body one and the top surface of main body two. After main body one and main body two are assembled vertically, a complete A material inlet and A material flow channel are formed.

[0008] Preferably, the diversion insert is provided with insert cover plates on the left and right outer sides, and the insert cover plates are connected to the main body and the discharge plate by screws.

[0009] Preferably, the B material inlet is located on the top surface of the main body.

[0010] This invention can achieve the composite of different raw materials in the width direction of the colored strip solar film, and can change the width of the A layer raw material by changing the flow channel of the splitting insert. By replacing different distributors, it can be used with the same extrusion die to extrude colored strip solar films with different A raw material width ratios. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] like Figures 1 to 8 As shown, this invention provides a co-extrusion distributor for colored striped solar films, comprising a main body 1, a second main body 2, a diverter block 3, and a discharge plate 4 arranged from top to bottom. The main body 1 is provided with a B material inlet 5, the second main body 2 is provided with an A material inlet 6 on its side, the second main body 2 is provided with a B material channel 7 vertically arranged in the middle of its upper and lower surfaces, the diverter block 3 is provided with a composite channel 8 in the middle corresponding to the B material channel 7, the second main body 2 is provided with an A material flow channel 9 extending to the left and right sides and then penetrating the second main body 2, the diverter block 3 is provided with A material diverter channels 10 on the upper surface of the diverter block 3 located on the left and right sides of the composite channel 8, the A material diverter channels 10 are diverted in the diverter block 3 and then converge in the width direction of the front and rear sides of the composite channel 8 at the lower part of the composite channel 8, and the discharge plate 4 is provided with a discharge port 11 corresponding to the bottom of the composite channel 8. The raw material formed by the A material and B material after being combined in the composite channel 8 is extruded from the discharge port 11.

[0022] Based on the above technical solution, the A material diversion channel 10 includes a horizontal section channel 101 and a vertical section channel 102. The horizontal section channel 101 extends smoothly from the outside to the inside and front and back sides of the composite channel 8. When it reaches the front and back positions of the composite channel 8, it enters the vertical section channel 102 downward. A conical diversion block 12 with a larger top and a smaller bottom is provided on the top surface of the vertical section channel 102 for guiding the flow. A conical baffle 13 with a larger top and a smaller bottom is provided between the upper part of the vertical section channel 102 and the composite channel 8. The bottom end of the conical baffle 13 terminates at the lower part of the vertical section channel 8. The A material contacts and combines with the B material in the composite channel 8 at the lower part of the vertical section channel 102 to form a composite raw material with an ABA structure in the width direction.

[0023] The A material inlet 6 and A material flow channel 9 are located at the junction of main body 1 and main body 2. Half of the inlet and the flow channel are respectively opened on the bottom surface of main body 1 and the top surface of main body 2. After the main body 1 and main body 2 are assembled, the complete A material inlet 6 and A material flow channel 9 are formed.

[0024] In addition, the shunt insert 3 is provided with insert cover plates 14 on the left and right outer sides, which are connected to the main body two 2 and the discharge plate 4 by screws.

[0025] Further, the B material feeding port 5 is arranged on the top surface of the main body one 1.

[0026] The working process of the present application is as follows: first, the B raw material enters the main body one 1 from the B material feeding port 5 on the top of the main body one 1, and then enters the composite channel 8 after passing through the main body one 1 and the main body two 2. The A raw material enters from the A material feeding port 6, and flows to the left and right sides of the B material channel 7 along the A material flow channel 9 in the main body two 2, and then vertically passes through the main body two 2 to reach the A material shunt channel 10 on the shunt insert 3. The A material first reaches the horizontal section flow channel 101, and then flows from the outside to the inside to the tapered shunt block 12 on the front and rear sides of the composite channel 8. After being guided by the tapered shunt block 12, the A material enters the vertical section flow channel 102. At this time, the A material and the B material are separated by the tapered baffle 13, and the A material flows downward along the tapered baffle 13 until it disappears at the bottom end of the tapered baffle 13, and then directly contacts and composites with the B material on the two sides of the B material in the width direction at the lower part of the composite channel 8, forming ABA composite raw material in the width direction, and then being extruded from the discharge port 11 of the discharge plate 4. Finally, the ABA composite raw material in the width direction is extruded through the extrusion die to form a fixed-width and proportion color strip solar film.

[0027] The above is only a preferred embodiment of the present application, and does not limit the application in any form. Any simple modification, equivalent change or modification made according to the technical principles of the present application to the above embodiment still falls within the scope of the technical solutions of the present application.
