[0029] Please refer to Figures 1-5 The utility model provides an embodiment:

[0030] A screw rod detachable double-screw extrusion puffing machine, it includes:

[0031] The top of the barrel 1 is provided with a top cover 2, the top cover 2 is fixedly inserted with a feed hopper 3 on one side of the top, the bottom of the top cover 2 is fixedly installed with symmetrically distributed positioning sliding plates 5, the top of the barrel 1 is provided with symmetrically distributed positioning sliding grooves 7, and the positioning sliding grooves 7 are slidably connected with the positioning sliding plates 5, the top cover 2 is provided with a fixing mechanism on one side of the top, one end of the barrel 1 is fixedly installed with a discharge pipe 6, and the discharge pipe 6 is provided with a die 17 at one end;

[0032] The other end of the barrel 1 is provided with symmetrically distributed external holes 9, and the barrel 1 is installed with driving shafts 11 through the external holes 9, and the barrel 1 is rotatably installed with spiral screws 12 inside, and the number of the spiral screws 12 is two, one end of the two spiral screws 12 is connected with one end of the two driving shafts 11 inside the barrel 1, and the other end of the two spiral screws 12 is rotatably connected with the bearing installed on one side of the inner wall of the barrel 1.

[0033] One end of the discharge pipe 6 is provided with symmetrically distributed limiting grooves 16, the outer surface of the die 17 is fixedly installed with symmetrically distributed limiting blocks 15, the limiting blocks 15 are matched with the limiting grooves 16, the end of the limiting blocks 15 away from the die 17 is fixedly installed with a fixing block 14, the outer wall of one end of the discharge pipe 6 is fixedly installed with positioning blocks 20 corresponding in position and number with the limiting grooves 16, the positioning blocks 20 are provided with clamping grooves 19, the side of the fixing block 14 close to the positioning blocks 20 is fixedly installed with a lead screw 13, and the outer wall of the lead screw 13 is threadedly connected with a butterfly nut 18.

[0034] In one embodiment, the outer diameter of the lead screw 13 is slightly smaller than the inner diameter of the clamping groove 19, so that the lead screw 13 can be easily inserted into the clamping groove 19, facilitating the installation operation of the mold 17.

[0035] In one preferred embodiment, the fixing mechanism includes a plurality of mounting holes 10, which are equidistantly arranged on one side of the top of the top cover 2, and the top of the barrel 1 is provided with mounting grooves 8 corresponding in position and number to the mounting holes 10, and the mounting holes 10 are threadedly connected with fixing bolts 4, which are threadedly connected with the mounting grooves 8.

[0036] In one embodiment, the structure of the positioning slide plate 5 is T-shaped, and the positioning slide plate 5 is adapted to the positioning slide 7, and the T-shaped structure increases the contact area between the positioning slide plate 5 and the positioning slide 7, improving the stability of their connection, and avoiding the shaking and displacement of the top cover 2 during sliding or working.

[0037] In one preferred embodiment, one end of the positioning slide 7 is in communication with one side of the barrel 1, and is not in communication with the other side of the barrel 1, ensuring the accuracy and stability of the disassembly and installation process of the top cover 2, avoiding the deviation of the top cover 2 from the predetermined path during sliding, and also limiting the sliding range of the top cover 2 to a certain extent.

[0038] In one embodiment, a sealing gasket is arranged at the connection between the bottom of the top cover 2 and the top of the barrel 1, which can enhance the sealing property of the device, prevent material leakage, ensure a clean working environment, and improve the utilization efficiency of the material.

[0039] The working principle of the utility model is as follows: the parts not mentioned in the device are consistent with the prior art or can be realized by means of the prior art. In the use process, if the screw rod 12 inside the barrel 1 needs to be disassembled, the fixing bolts 4 at the top of the top cover 2 are first disassembled by using tools, and the fixed connection between the top cover 2 and the barrel 1 is released. Then the top cover 2 is pulled to one side, and when the top cover 2 moves on the top of the barrel 1, the positioning slide plate 5 at the bottom of the top cover 2 forms sliding contact with the positioning slide 7 at the top of the barrel 1, until the positioning slide plate 5 is separated from the positioning slide 7, that is, the disassembly operation of the barrel 1 is completed. At this time, the top of the barrel 1 is completely open, providing a spacious operating space for the workers, facilitating them to quickly disassemble and assemble the screw rod 12 inside the barrel 1, and improving the use convenience. In addition, when the top cover 2 is installed on the top of the barrel 1, the sliding insertion of the positioning slide plate 5 and the positioning slide 7 ensures that the top cover 2 can be tightly closed on the top of the barrel 1, and the fixing of the barrel 1 and the top cover 2 is realized by using the fixing bolts 4 on one side of the top cover 2. This way of using a small number of fixing bolts 4 not only realizes the tight fixing of the top cover 2 on the top of the barrel 1, but also enables quick disassembly, avoiding the use of a large number of bolts to fix the top cover 2 on the top of the barrel 1, and having high practicality.

[0040] In use, in the working state, the two helical screws 12 will transport the material entering through the feed hopper 3, so that it is extruded through the die 17 on the discharge pipe 6. When it is necessary to replace different dies 17, the operator can manually turn the butterfly nut 18 on the outer wall of the lead screw 13, and unscrew it from the lead screw 13, and then directly pull out the two fixing blocks 14. The movement of the fixing blocks 14 will cause the lead screw 13 to be detached from the inside of the clamping groove 19, and at the same time, the limiting block 15 will also be detached from the inside of the limiting groove 16, so that the die 17 is directly detached from the port of the discharge pipe 6. The detachable function of the die 17 is realized, and the detachable structure of the die 17 is simple and convenient to operate, and the worker can complete the disassembly and assembly of the die 17 without the aid of any tool, which greatly facilitates the replacement of different specifications of the die 17.
