Description

Technical Field

[0001] This utility model belongs to the field of screw extruders, specifically relating to a screw extruder for the production of long-fiber TPU composite materials. Background Technology

[0002] Screw extruders are divided into two types: cold-feed screw extruders and hot-feed screw extruders. Both are used for extruding rubber semi-finished products and finished products. Cold-feed screw extruders can feed unprocessed rubber compounds, which are then plasticized by the screw through extrusion, shearing, and mixing, and continuously extruded through the die. Hot-feed screw extruders, on the other hand, require the feeding of hot-processed rubber compounds, which are then further plasticized and continuously extruded through the screw through extrusion, shearing, and mixing. When extruding long-fiber TPU composite materials, excessive raw material is often added to the hopper at one time, which can easily cause blockages in the hopper, affecting the normal extrusion operation of the screw extruder. This issue urgently needs improvement.

[0003] This invention seeks to mitigate or at least alleviate such problems or defects by providing a new or otherwise improved screw extruder. Utility Model Content

It includes a workbench 1 with a mounting plane; a screw extrusion component 2, which includes a base plate 21 detachably mounted on the mounting plane; an extrusion cylinder 22 with a detachably mounted feeding hopper 23, and a sleeve seat 24 slidably mounted on the outside of the extrusion cylinder 22, and the sleeve seat 24 is connected to the base plate 21; a first drive motor 25 detachably mounted on the base plate 21, and a screw 29 detachably mounted at the output end of the first drive motor 25, and the screw 29 can penetrate into the extrusion cylinder 22; a first flange 26 detachably mounted on one end of the extrusion cylinder 22; a discharge cylinder 28 with a detachably mounted second flange 27, and the second flange 27 is detachably connected to the first flange 26; and a material outlet unblocking component 3 detachably mounted on the feeding hopper 23.

[0020] The overall concept of this utility model is as follows: the raw material is placed into the feed hopper 23 through the screw extrusion component 2. By turning on the first drive motor 25, the screw 29 can be rotated to extrude the raw material and make it flow out from the discharge cylinder 28. Through the feed port unblocking component 3, the operator can drive the drive wheel 34 to rotate by turning on the second drive motor 33. When the drive wheel 34 rotates, it can drive the driven wheel 36 and the unblocking rod 35 to rotate. At the same time, it can sequentially drive the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39 to rotate. By gradually decreasing the length of the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39, the blockage of the raw material in the feed hopper 23 can be further prevented, and the extrusion operation of the raw material by the screw extrusion component 2 can be accelerated.

[0022] In some embodiments, more specifically, a discharge port is provided inside the discharge cylinder 28, and the diameter of the discharge port is adapted to the diameter of the discharge cylinder 28.

[0023] In some embodiments, more specifically, the size of the screw 29 is adapted to the size of the extrusion barrel 22, and the screw 29 and the interior of the extrusion barrel 22 form an extrusion cavity.

[0024] In some embodiments, in order to facilitate quick insertion and disassembly between the hopper 23 and the extrusion cylinder 22, an insertion cavity is provided at the top of the extrusion cylinder 22, and an insertion tube is removably inserted through the bottom of the hopper 23, and the insertion tube can be inserted into the insertion cavity.

[0025] Next, a more specific structure and construction of the material inlet unblocking component 3 will be given for further explanation. The material inlet unblocking component 3 includes a connecting plate 31, which is detachably installed on the upper hopper 23, and a side lug 32 is detachably installed on it; a second drive motor 33, which is detachably arranged on the side lug 32, and a drive wheel 34 is detachably installed at the output end of the second drive motor 33; an unblocking rod 35, which is rotatably arranged on the connecting plate 31, and the unblocking rod 35 can pass into the upper hopper 23; a driven wheel 36, which is detachably installed at the top of the unblocking rod 35, and the driven wheel 36 meshes with the drive wheel 34; an upper unblocking impeller 37, which is detachably installed on the unblocking rod 35; a middle unblocking impeller 38, which is detachably installed on the unblocking rod 35; and a lower unblocking impeller 39, which is detachably installed on the unblocking rod 35. Next, the working principle and effect of the material outlet unblocking component 3 will be further explained. When the operator turns on the second drive motor 33, the drive wheel 34 can be driven to rotate. When the drive wheel 34 rotates, it can drive the driven wheel 36 and the unblocking rod 35 to rotate. At the same time, it can drive the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39 to rotate in sequence. By gradually reducing the length of the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39, the blockage of raw materials in the feed hopper 23 can be further prevented, and the extrusion operation of raw materials by the screw extrusion component 2 can be accelerated.

[0026] In some embodiments, more specifically, the length of the upper dredging impeller 37 is greater than the length of the middle dredging impeller 38, and the length of the middle dredging impeller 38 is greater than the length of the lower dredging impeller 39.

[0027] In some embodiments, more specifically, a bottom cleaning impeller 391 is detachably installed on the cleaning rod 35, and the bottom cleaning impeller 391 is located below the bottom cleaning impeller 39, and the length of the bottom cleaning impeller 391 is less than the length of the bottom cleaning impeller 39.

[0028] In summary, the raw material is placed into the feed hopper 23 through the screw extrusion component 2. By turning on the first drive motor 25, the screw 29 can be rotated to extrude the raw material and make it flow out from the discharge cylinder 28. Through the feed port unblocking component 3, the operator can drive the drive wheel 34 to rotate by turning on the second drive motor 33. When the drive wheel 34 rotates, it can drive the driven wheel 36 and the unblocking rod 35 to rotate. At the same time, it can drive the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39 to rotate in sequence. By gradually decreasing the length of the upper unblocking impeller 37, the middle unblocking impeller 38, and the lower unblocking impeller 39, it is possible to further prevent the raw material from clogging in the feed hopper 23 and speed up the extrusion operation of the raw material by the screw extrusion component 2.
