Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to an integrated feeding and pressing device for an extruder. Background Technology

[0002] Extruders are industrial equipment widely used in industries such as plastics, rubber, food, metals, and pharmaceuticals. Their main function is to heat, plasticize, and pressurize materials to form continuous products of specific shapes through molds or orifices. However, current production processes typically involve multiple separate workstations performing a series of production operations. First, the raw material is transported from the outside to the extruder via a feeder. Then, the screw of the extruder rotates and heats the material, melting and plasticizing it. Finally, it is transported to a pressure platen for extrusion molding, ultimately forming the desired product shape. Because the raw material processing is completed in different machines, there is a lack of effective and controllable connection between these processes. The process also requires repeated material transport, which is time-consuming and labor-intensive, impacting production efficiency and quality. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an integrated feeding and pressing device for extruders. This device has a compact structure and a reasonable design.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, this utility model discloses an integrated feeding and pressing device for an extruder, comprising a feeding assembly 1, a pressing assembly 2 used in conjunction with the feeding assembly 1, and a feeding channel 3 disposed between the feeding assembly 1 and the pressing assembly 2. The feeding assembly 1 includes a drive shaft 11, a first motor 12 drivenly connected to the drive shaft 11, and a helical spring 13 disposed on the drive shaft 11. The pressing assembly 2 includes an output shaft 21, a second motor 22 drivenly connected to the output shaft 21, and a stirring body 23 disposed on the output shaft 21. The first motor 12 drives the helical spring 13 to rotate through the drive shaft 11, thereby pushing the material along the feeding channel 3 into the stirring body 23. The central axis of the helical spring 13 is perpendicular to the central axis of the stirring body 23.

[0028] During operation, raw materials (such as plastic granules, powders, or other materials) are conveyed to the feeding assembly 1, which is mainly used to transport the raw materials from the inlet to the outlet. Specifically, the first motor 12 drives the drive shaft 11 to rotate, which in turn drives the helical spring 13 to propel the raw materials forward along the length of the feeding channel 3, achieving horizontal conveying of the raw materials until they are conveyed into the mixing body 23. The second motor 22 drives the mixing body 23 to rotate via the output shaft 21. Because the central axis of the helical spring 13 is perpendicular to the central axis of the mixing body 23, the mixing body 23 compresses and squeezes the raw materials in the vertical direction. Finally, the mixing body 23 extrudes the raw material granules into shape through rotational motion, greatly saving floor space, exhibiting high structural compactness, and ensuring efficient and uninterrupted operation. This utility model has a compact structure and reasonable design. By concentrating the feeding assembly 1 and the pressing assembly 2 in one device, the corresponding processing and production operations of the raw materials are completed within one device, realizing automated extrusion molding and improving production efficiency and quality.

[0029] The pressing assembly 2 in this embodiment also includes a stand 24, a tank 25 sleeved on the outside of the mixing body 23, a connecting cylinder 26 disposed on the tank 25, a mounting base 27 disposed on the connecting cylinder 26, a screw 28 rotatably connected to the mounting base 27, a nut 29 disposed on the screw 28, and a groove 210 disposed on the stand 24. The connecting cylinder 26 is connected to the feeding channel 3. A pin 211 is provided at the connection between the screw 28 and the mounting base 27 so that the screw 28 protrudes into the groove 210 and is threadedly connected to the nut 29. A washer 212 is provided between the nut 29 and the groove 210. Specifically, the second motor 22 drives the agitator 23 to rotate inside the tank 25 via the output shaft 21, causing the raw materials to be extruded under high pressure within the enclosed space of the tank 25, resulting in high molding efficiency. The connecting cylinder 26 is detachably connected to the tank 25, and the mounting base 27 is located on the outer wall of the connecting cylinder 26. The screw 28 is rotatably connected to the mounting base 27 via the pin 211, so that the screw 28 protrudes into the groove 210 and is threadedly connected to the nut 29. Moreover, a washer 212 is provided between the nut 29 and the groove 210. The washer 212 can increase the contact area between the nut 29 and the groove 210, disperse local compressive stress, and play a mechanical locking role. By installing or removing the connecting cylinder 26, daily maintenance and repair are convenient, and the working status of the agitator 23 inside the tank 25 can be more directly observed, effectively detecting and dealing with any abnormalities in the working of the agitator 23.

[0030] The stirring body 23 in this embodiment includes a stirring shaft 231 and spiral blades 232 spirally surrounding the outside of the stirring shaft 231. The stirring body 23 is rotatably housed within the tank 25. Specifically, the stirring shaft 231 is connected to the output shaft 21 via a coupling. The spiral blades 232 spirally surround the outside of the stirring shaft 231. The stirring shaft 231 drives the spiral blades 232 to rotate at high speed, simultaneously performing the functions of stirring, mixing, and extruding raw materials, ensuring uniform extrusion molding of the raw materials and high molding efficiency.

[0031] In this embodiment, a discharge port 213 is provided at the end of the tank 25 away from the connecting cylinder 26. Specifically, the raw material is extruded and formed by the spiral blades 232 and squeezed downward along the tank 25 to the discharge port 213 for easy discharge and transportation.

[0032] The feeding assembly 1 in this embodiment further includes a stand 14, a cavity 15 disposed on the stand 14, and a hopper 16 disposed on the cavity 15. The first motor 12 is mounted on the outside of the stand 14, and the drive shaft 11 protrudes into the cavity 15 so that the helical spring 13 extends into the feeding channel 3. Specifically, the hopper 16 is disposed at the top of the cavity 15. Raw materials are input into the cavity 15 through the hopper 16. The first motor 12 drives the helical spring 13 to extend into the feeding channel 3 through the drive shaft 11. During the rotation of the helical spring 13, the raw materials are transported from the position of the hopper 16 to the position of the feeding channel 3, resulting in high feeding efficiency.
