Description

Technical Field

In the industry, polypropylene granule molding production generally adopts mechanical extrusion and single-plane softening methods, which are inefficient and sometimes result in air bubbles within the molded product, affecting the quality of the granules. This device, by placing heating rods of varying sizes in the feeding box, ensures a high degree of fusion of the polypropylene material at the top, while the lower part continuously provides the required softness, hardness, and binding strength with a small amount of heat. Furthermore, pressure is applied from above by a pressurized air pump, resulting in more uniform pressure application than traditional physical pressurization, leading to a higher yield of finished products. The quick-disassembly assembly facilitates cleaning and significantly improves the ease of use of this device.

[0032] In use, the raw material is first fed into the discharge cylinder 3 through the feeding port. The first motor 401 is turned on, which drives the screw propeller 402 to rotate. The screw propeller 402 is equipped with a heating coil, which heats and melts the raw material and pushes it forward until it reaches the discharge hole at the front end of the discharge cylinder 3. The melted raw material is discharged in a long strip through the discharge hole and falls into the water cooling tank 2, which allows the raw material to cool and solidify quickly.

Under the action of the first and second rotating rods 502 and 503, the solidified long strip of material is driven into the cutting box 601.

The water is mixed with the cold water pre-stored in the cold water tank 508 and cooled down before being discharged into the water-cooled tank 2 through the outlet 505, so that the cooling water temperature inside the water-cooled tank 2 remains constant.

[0039] Specifically, the cutting assembly 6 includes a cutting box 601 and a connecting rod 603; the cutting box 601 is installed at the front end of the water-cooling tank 2; and the connecting rod 603 is located inside the cutting box 601.

[0040] Furthermore, the solidified elongated raw material enters the cutting box 601, and the third motor 604 is turned on, which in turn drives the connecting rod 603 to rotate.

[0041] Specifically, the cutting assembly 6 includes: a cutting blade 602 and a third motor 604; the cutting blade 602 is welded to the surface of the connecting rod 603; the third motor 604 is keyed to one end of the connecting rod 603.

The hot air blower 702 is turned on to dry the surface moisture of the granular raw materials. Since the filter plate 703 is inclined, the granular raw materials will slide down to the discharge port of the drying chamber 701 under the vibration of the vibrating motor 704.

Turning on the second motor 501 rotates the first rotating rod 502, which in turn rotates the first gear 509. The second gear 510 meshes with the first gear 509, causing the second gear 510 to rotate, which in turn rotates the second rotating rod 503. Under the action of the first and second rotating rods 502 and 503, the cured long strip of raw material is drawn into the cutting box 601. This invention also involves turning on the third motor 604, which rotates the connecting rod 603.
