[0020] The following will further describe the technical solution of the utility model in conjunction with the drawings of the embodiments of the utility model, and the utility model is not limited to the following specific implementation methods. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] like Figures 1 to 3 As shown, a novel T-type rubber extruder head comprises: a mounting plate 100, an extrusion channel 200, a diverter mechanism and a head body; a connecting port is opened on the mounting plate 100, the extrusion channel 200 is arranged on the mounting plate 100, and the extrusion channel 200 is connected with the connecting port, the diverter mechanism is arranged on the mounting plate 100, and the diverter mechanism is located on the outside of the extrusion channel 200; the head body is arranged on the mounting plate 100, and the head body is located on the outside of the diverter mechanism.

[0022] Specifically, the mounting plate 100 is provided with a plurality of mounting holes 101, and the mounting plate 100 is connected to the outside through the plurality of mounting holes 101. An extrusion port is provided at one end of the extrusion flow channel 200, and the extrusion port is communicated with the extrusion flow channel 200. The diversion mechanism includes a fixed seat 310, a plurality of first diversion blocks 320, and a plurality of second diversion blocks 330. The fixed seat 310 is used to be connected to the mounting plate 100, and the plurality of first diversion blocks 320 and the plurality of second diversion blocks 330 are all arranged on the fixed seat 310. Each of the first diversion blocks 320 is arranged at intervals with a second diversion block 330. The fixed seat 310 is provided with a plurality of diversion channels 340, and each of the first diversion blocks 320 has a diversion channel 340 on both sides, and each of the second diversion blocks 330 has a diversion channel 340 on both sides. That is to say, by setting a plurality of first diverter blocks 320 and a plurality of second diverter blocks 330, the special rubber flowing through can be diverted, that is, the special rubber can flow to each diverter channel 340. A glue inlet is provided on the fixing seat 310, and the glue inlet is connected to each of the diverter channels 340. Each of the diverter channels 340 is opened at an angle. A first curved surface 321 is provided on one surface of each of the first diverter blocks 320, and each of the first curved surfaces 321 can allow rubber to flow through. A second curved surface 331 is provided on one surface of each of the second diverter blocks 330, and each of the second curved surfaces 331 can allow rubber to flow through. By setting the first curved surface 321 and the second curved surface 331, the special rubber flowing through can be more uniform, so the problem of forming a connection mark at the connection of the rubber after extrusion can be better avoided.

[0023] That is to say, by installing this new T-shaped rubber extruder head on an external rubber extruder, through the coordination between the mounting plate 100, the extrusion flow channel 200, the diversion mechanism and the head body, the problem of the extruded rubber forming a connection mark at the connection point, which may lead to unqualified products after molding, is effectively avoided, thereby improving the product quality rate and reducing the overall processing cost.

[0024] It is worth mentioning that by setting up a diversion mechanism, that is, forming a diversion and flow resistance area on the die head, the diversion and flow resistance area can well target the fluidity of the T-type die head, that is, make the flow uniform. Furthermore, when the melt flows through this part, the middle part is higher than the flow channels on both sides, and the melt flows slowly in the fan-shaped flow channel, thereby improving the overall flow uniformity and facilitating the overall molding.

[0025] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
