Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a high-twist flat double extruder with an anti-blocking hopper. Background Technique

[0002] According to the included angle between the material flow direction of the head and the center line of the screw, the head of the extruder can be divided into a right-angle head, an oblique-angle head, etc. The screw extruder relies on the pressure and shear force generated by the rotation of the screw, which can enable the material to be fully plasticized and evenly mixed, and formed through the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders.

[0003] In the process of plastic processing, an extruder is often needed. When the extruder is in use, raw materials need to be added into the extrusion barrel manually through the feed pipe. However, sometimes, due to excessive addition of raw materials, the feed pipe is prone to blockage, which in turn affects the subsequent extrusion efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-twist flat double extruder with an anti-blocking hopper to solve the problems existing in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-twist flat double extruder with an anti-blocking hopper, including a base, an extruder body and a motor respectively arranged on the top thereof, and a feeding hopper communicated with the top of the extruder body, further including:

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 As shown in the figure, a high-torque flat double extruder with a clogging-proof hopper includes a base 1. An extruder body 2 and a motor 3 are respectively arranged on the top of the base 1. The output end of the motor 3 is fixed to the rotating shaft of the extruder body 2. The top of the extruder body 2 is communicated with a feeding hopper 4. A fixing plate 5 is fixedly connected to the top of the feeding hopper 4. A rotating rod 6 is rotatably connected to the bottom of the fixing plate 5. A screw blade 7 is fixedly connected to the surface of the rotating rod 6. A transmission structure 8 for driving the rotating rod 6 to rotate is arranged on the left side of the feeding hopper 4. A folding plate 9 is fixedly connected to the left side of the feeding hopper 4. A movable rod 10 is movably connected inside the folding plate 9. One end of the movable rod 10 is fixedly connected to a knocking plate 11. The other end of the movable rod 10 is fixed with a pushing plate 12. A spring 13 is sleeved on the surface of the movable rod 10, and both ends of the spring 13 are fixedly connected between the pushing plate 12 and the folding plate 9. A force-applying structure 14 for applying force to push the pushing plate 12 is arranged on the left side of the folding plate 9.

[0022] The transmission structure 8 includes a driving wheel 81, a driven wheel 82, a transmission rod 83, a first bevel gear 84 and a second bevel gear 85. The driving wheel 81 is fixed on the surface of the rotating shaft of the extruder body 2. The driving wheel 81 is in transmission connection with the driven wheel 82 through a belt. The right side of the driven wheel 82 is fixed to one end of the transmission rod 83. The other end of the transmission rod 83 extends into the feeding hopper 4 and is fixed to one side of the first bevel gear 84. The other side of the first bevel gear 84 is meshed with the second bevel gear 85. The inside of the second bevel gear 85 is fixed to the surface of the rotating rod 6. In this way, with the drive of the motor 3, the driving wheel 81 can be driven to rotate, and at the same time, the driven wheel 82 is driven to rotate through the belt, then the transmission rod 83 and the first bevel gear 84 are driven to rotate, and the second bevel gear 85 and the rotating rod 6 are driven to rotate.

[0023] The force application structure 14 includes a third bevel gear 141, a fourth bevel gear 142, a long rod 143, and a cam 144. The third bevel gear 141 is fixed on the surface of the transmission rod 83. The bottom of the fourth bevel gear 142 meshes with the top of the third bevel gear 141. One end of the long rod 143 is fixed to the top of the fourth bevel gear 142, and the other end of the long rod 143 is fixed to one side of the cam 144. Thus, with the rotation of the transmission rod 83, the third bevel gear 141 will be driven to rotate, and at the same time, the fourth bevel gear 142, the long rod 143, and the cam 144 will be driven to rotate, so that the protruding part of the cam 144 rotates to the right, thereby facilitating the application of force to push the push plate 12.

[0024] A plurality of rollers 15 are rotatably connected to the left side surface of the push plate 12, and the surface of the rollers 15 is in rolling connection with the cam 144. Thus, the friction between the cam 144 and the push plate 12 can be reduced, facilitating better application of force to push the push plate 12.

[0025] A shielding plate 17 is fixedly connected to the surface of the rotating rod 6, and the shielding plate 17 is located above the first bevel gear 84. Thus, the first bevel gear 84 and the second bevel gear 85 can be shielded to prevent particles from entering the teeth of the first bevel gear 84 and the second bevel gear 85.

[0026] A support plate 16 is fixedly connected to the bottom of the folded plate 9, and the inside of the support plate 16 is rotatably connected to the surface of the transmission rod 83. Thus, the transmission rod 83 can be supported assistingly and its stability during rotation can be maintained.

[0027] It should be noted that: in this technical solution, technical features such as... should be regarded as the prior art. For the specific structures, working principles, and possible control methods and spatial arrangement methods involved in these technical features, the conventional selections in this field can be adopted, and this technical solution will not be further specifically elaborated.

[0028] Working principle: When in use, driven by the motor 3, the rotating shaft of the extruder body 2 will rotate. Then, plastic particles can be poured into the interior of the feeding hopper 4. As the rotating shaft of the extruder body 2 rotates, the rotating rod 6 and the auger blade 7 will be driven to rotate by the transmission structure 8, so that the plastic particles can be conveyed downward, thus avoiding particle blockage. At the same time, with the transmission of the transmission structure 8, the third bevel gear 141 will be driven to rotate, and at the same time, the fourth bevel gear 142, the long rod 143 and the cam 144 will be driven to rotate, so that the protruding part of the cam 144 rotates to the right, thus facilitating the application of force to push the push plate 12. When the push plate 12 moves to the right, it will drive the movable rod 10 and the knocking plate 11 to move together and squeeze the spring 13. At this time, the knocking plate 11 will knock on the feeding hopper 4. After the cam 144 rotates to the starting position, the spring 13 will apply force through its own elasticity and drive the push plate 12 back to the starting position again. Repeating this way to knock on the feeding hopper 4 can further improve the feeding rate.

Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
