[0002] PVC hose is made of PVC resin with a large amount of plasticizer, a certain amount of stabilizer and other additives, and then extruded. Soft PVC tube has excellent chemical stability, excellent electrical insulation performance, good flexibility and colorability. This kind of tube is often used to replace rubber tubes to transport liquids and corrosive media, and is also used as cable sheaths and wire insulation.
[0003] In the process of manufacturing PVC hose, an extruder is used for manufacturing. After the hose is produced, it needs to be directly pulled into a cooling mechanism for cooling. However, due to its poor hardness and toughness after extrusion, the hose will be deformed and damaged if it is directly pulled and bent. In addition, the raw materials are easily blocked during input, resulting in discontinuity of production. For this reason, we propose a melt extruder for PVC hose production. Utility Model Content

[0017] See also Figure 1-Figure 3 The utility model provides a technical solution: a melt extruder for producing PVC hose, comprising a working frame 1, a driving box 2 is fixedly installed on the top of the working frame 1, a conveying barrel 3 is connected to one side of the driving box 2, a protective shell 4 is fixedly connected to the top of the working frame 1 and the outer surface of the conveying barrel 3, an extrusion head 5 is fixedly connected to one end of the conveying barrel 3, a feed bin 6 is fixedly connected to the top of the conveying barrel 3, an anti-blocking mechanism 7 for preventing the material from being stuck is arranged inside the feed bin 6, a receiving mechanism 8 for receiving the hose is fixedly installed on one side of the working frame 1 and corresponding to the position of the extrusion head 5, and an adjustment mechanism 9 for adjusting the upper and lower positions of the receiving mechanism 8 is fixedly installed on one side of the working frame 1.
[0018] Among them, by setting up a feed bin 6, the material can be put into the interior of the conveying barrel 3, and then it is extruded and formed by using the extruder head 5, and the anti-blocking mechanism 7 set inside the feed bin 6 can prevent the material from being blocked between the feed bin 6 and the conveying barrel 3, thereby ensuring the complete extrusion of the material. The material receiving mechanism 8 set after the hose extrusion is completed can support the hose, thereby preventing the material from being deformed and damaged when it is pulled and cooled, and the adjustment mechanism 9 set can adjust the upper and lower positions of the material receiving mechanism 8, so that it can effectively support it when using different mechanisms to extrude hoses of different specifications using extruder heads 5.
[0019] See also Figure 1 and Figure 2The material receiving mechanism 8 includes a slide rail 10, a slider 11, a connecting plate 12, a support frame 13, a bearing seat 14 and a material receiving roller 16. Two groups of slide rails 10 are fixedly installed on one side of the working frame 1. The slide rail 10 is slidably connected with a slider 11. The two groups of sliders 11 are fixedly connected through a connecting plate 12. One side of the connecting plate 12 is fixedly connected with two groups of support frames 13. The top of the support frame 13 is fixedly installed with a bearing seat 14. The inside of the bearing seat 14 is rotatably connected with a rotating shaft 15. The outer surface of the rotating shaft 15 is fixedly installed with a material receiving roller 16. The manufacturing material of the material receiving roller 16 is rubber material. The top of the material receiving roller 16 and the bottom of the extruder head 5 are located at the same horizontal plane.
[0020] After the extruder 5 extrude the hose, the hose is overlapped on the top of the receiving roller 16. Then, when the hose is pulled, the hose rotates along the receiving roller 16 and the rotating shaft 15, thereby preventing the hose from bending and deforming when being pulled.
[0021] See also Figure 1 and Figure 2 The adjustment mechanism 9 includes a first fixed plate 17, a second fixed plate 18, a screw sleeve 19 and a threaded rod 20. The first fixed plate 17 and the second fixed plate 18 are fixedly installed on one side of the work frame 1, and the screw sleeve 19 is fixedly installed on the second fixed plate 18. The internal thread of the screw sleeve 19 is connected with the threaded rod 20. The top of the threaded rod 20 is rotatably connected to the bottom of the first fixed plate 17.

The bottom of the threaded rod 20 is fixedly connected with a turning handle 21.
[0022] Among them, after the extrusion head 5 is replaced, because the size of the hose extruded by the extrusion head 5 is different, by rotating the handle 21, the handle 21 drives the threaded rod 20 to rotate along the screw sleeve 19, and then the rotating threaded rod 20 can be used to drive the slider 11, the connecting plate 12, the support frame 13, the bearing seat 14 and the material receiving roller 16 to move up and down along the slide rail 10, so that the top of the material receiving roller 16 can be supported by the corresponding hose.
[0023] See also Figure 1 , Figure 2 and Figure 3 The anti-blocking mechanism 7 includes a support plate 23 and a motor 24. The support plate 23 is fixedly installed on the top of the inner wall of the feed bin 6, and the motor 24 is fixedly installed on the support plate 23. The output end of the motor 24 is fixedly connected to a connecting rod 25, and the bottom of the outer wall of the connecting rod 25 and corresponding to the bottom of the feed bin 6 is fixedly connected to a swing rod 27 through a fixed block 26.
[0024] Among them, after the material is put into the feed bin 6, the motor 24 is started to rotate, and the motor 24 can drive the connecting rod 25, the fixed block 26 and the swing rod 27 to rotate eccentrically, so as to prevent the connection between the feed bin 6 and the conveying barrel 3 from being blocked.
[0025] When in use, first, by setting the feed bin 6, the material can be put into the inside of the conveying barrel 3, and then the extruder head 5 is used to extrude it into shape, and the anti-blocking mechanism 7 set inside the feed bin 6 can prevent the material from being blocked between the feed bin 6 and the conveying barrel 3, thereby ensuring the complete extrusion of the material, and the material receiving mechanism 8 set after the hose is extruded can support the hose, thereby preventing the material from being deformed and damaged when it is pulled and cooled, and the adjustment mechanism 9 set can adjust the upper and lower positions of the material receiving mechanism 8, so that when different mechanisms are used to extrude hoses of different specifications using the extruder head 5, it can effectively support it. After the extruder head 5 extrude the hose, the hose is overlapped on the top of the material receiving roller 16, and then when the hose is pulled, the hose moves along the material receiving roller 16 and the rotating shaft. 15 is rotated, thereby preventing the hose from bending and deforming when being pulled. After the extruder head 5 is replaced, because the size of the hose extruded by the extruder head 5 is different, by rotating the handle 21, the handle 21 drives the threaded rod 20 to rotate along the screw sleeve 19, and then the rotating threaded rod 20 can be used to drive the slider 11, the connecting plate 12, the support frame 13, the bearing seat 14 and the material receiving roller 16 to move up and down along the slide rail 10, so that the top of the material receiving roller 16 can be supported by the corresponding hose. After the material is placed in the feed bin 6, the motor 24 is started to rotate, and the motor 24 can drive the connecting rod 25, the fixed block 26 and the swing rod 27 to rotate eccentrically, so that the connection between the feed bin 6 and the conveying barrel 3 can be prevented from being blocked.
