Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a raw material crushing mechanism for the production of plastic rattan. Background Technology

[0002] Plastic rattan is a type of artificial woven material widely used in the manufacture of furniture, decorations and handicrafts. Its raw materials are usually recycled or new plastic granules, sheet scraps and long plastic strips and plastic film rolls. Before entering the extrusion or wire drawing process, these raw materials often need to be crushed to obtain small particles that are uniform in size and easy to melt and plasticize.

[0003] Traditional raw material crushing mechanisms for plastic rattan production often involve directly feeding the material into a high-speed crusher or shredder. However, plastic rattan is prone to tangling, clumping, or uneven feeding during the feeding process, leading to blockages at the equipment inlet and requiring frequent shutdowns for cleaning. This severely impacts production continuity. Furthermore, long strips of material entering the crushing chamber directly can easily become entangled on the high-speed rotating cutter shaft, increasing the instantaneous load and causing equipment instability. Additionally, the pulling and tearing action, rather than effective cutting, exacerbates abnormal wear on the crushing blades and shortens their lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a raw material crushing mechanism for the production of plastic rattan. This addresses the problem that traditional raw material crushing mechanisms for plastic rattan production often involve directly feeding materials into a high-speed crusher or shredder. However, during the feeding process, plastic rattan is prone to entanglement, clumping, or uneven feeding, leading to blockage at the equipment inlet and requiring frequent shutdowns for cleaning, severely impacting production continuity. Furthermore, long strips of material directly entering the crushing chamber easily become entangled on the high-speed rotating cutter shaft, increasing the instantaneous load and causing equipment instability. Additionally, the pulling and tearing action, rather than effective cutting, exacerbates abnormal wear on the crushing blades, shortening their lifespan.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a raw material crushing mechanism for the production of plastic rattan, comprising a support frame, a housing fixedly mounted on the upper surface of the support frame, a feeding port mounted on the upper surface of the housing, a discharge port mounted on the lower surface of the housing, a crushing mechanism mounted inside the housing, a pre-compression mechanism mounted inside the housing, the pre-compression end of the pre-compression mechanism being positioned above the crushing mechanism, a cutting mechanism mounted inside the housing, the cutting end of the cutting mechanism being positioned between the crushing mechanism and the pre-compression mechanism, a limiting plate fixedly mounted on the inner wall of the housing, a cutting groove being formed on one side of the limiting plate, the position of the cutting groove corresponding to the cutting end of the cutting mechanism.

[0006] Furthermore, the pre-compression mechanism includes a second rotating shaft, which is rotatably connected to the inner wall of the housing, and the number of the second rotating shafts is fixed to two. Each of the outer surfaces of the second rotating shafts is fixedly mounted with a pressure roller. Each of the two second rotating shafts is fixedly mounted with a second gear at one end, and the two second gears are meshed with each other. A second motor is fixedly mounted on the outer surface of the housing, and the output end of the second motor is fixedly connected to one end of one of the second rotating shafts.

[0007] Furthermore, the cutting mechanism includes a mounting plate, on the upper surface of which a third motor is fixedly mounted, and at the output end of the third motor, a turntable is fixedly mounted.

[0008] Furthermore, two sliding sleeves are fixedly installed on one side of the housing, and sliding rods are slidably connected inside each sliding sleeve. Both sliding rods extend into the interior of the housing, and a fixing plate is fixedly installed at one end of each sliding rod. A cutting blade is fixedly installed on one side of the fixing plate. The cutting blade is located below the pressure roller and corresponds to the position of the cutting groove.

[0009] Furthermore, a connecting plate is fixedly installed at the other end of the two slide rods, and a connecting rod is rotatably connected to the outer surface of the connecting plate. One end of the connecting rod is rotatably connected to the lower surface of one end of the turntable.

[0010] Furthermore, the crushing mechanism includes a first rotating shaft, which is fixedly installed inside the housing and the number of the first rotating shafts is fixedly two. A plurality of crushing blades are fixedly installed on the outer surface of each of the first rotating shafts. A first motor is fixedly installed on the outer surface of the housing. The output end of the first motor is fixedly connected to one end of one of the crushing blades. A first gear is fixedly installed on the outer surface of one end of each of the first rotating shafts, and the two first gears mesh with each other.

[0011] This utility model has the following beneficial effects: (1) This utility model uses a pre-pressing mechanism to flatten and arrange the raw materials so that they can enter the cutting process evenly, effectively avoiding material entanglement and accumulation. Combined with a reciprocating cutting mechanism, the raw materials are pre-cut into short segments, making the subsequent crushing process smoother and more efficient, reducing the wear of the crushing blades, and improving the overall processing quality.

[0012] (2) The limiting plate fixed to the inner wall of the housing and the cutting groove thereon provide precise hard guidance and support for the reciprocating motion of the cutting blade. The cutting blade moves along the trajectory of the cutting groove, ensuring that it is always in contact with the raw material on the predetermined path, avoiding incomplete cutting or blade wobble caused by uneven force or raw material deviation, thereby ensuring that each cutting action can effectively cut the pre-compressed raw material, providing a regular-sized raw material segment for the subsequent crushing process.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The pre-compression mechanism 6 includes a second rotating shaft 601, which is rotatably connected to the inner wall of the housing 2. The number of second rotating shafts 601 is fixed to two. Pressure rollers 602 are fixedly installed on the outer surface of each second rotating shaft 601. A second gear 603 is fixedly installed at one end of each of the two second rotating shafts 601. The two second gears 603 are meshed with each other. A second motor 604 is fixedly installed on the outer surface of the housing 2. The output end of the second motor 604 is fixedly connected to one end of one of the second rotating shafts 601. Specifically, the pre-compression mechanism 6 is activated, and the second motor 604 drives the second rotating shaft 601 to drive the two pressure rollers 602 to rotate in opposite directions, so as to initially flatten and sort the plastic rattan raw material, making it more evenly enter the next process.

[0019] The cutting mechanism 7 includes a mounting plate 701, on the upper surface of which a third motor 702 is fixedly mounted, and at the output end of the third motor 702 a turntable 703 is fixedly mounted. Two sliding sleeves 704 are fixedly installed on one side of the housing 2. Sliding rods 705 are slidably connected inside the sliding sleeves 704. Both sliding rods 705 extend into the interior of the housing 2. A fixing plate 706 is fixedly installed at one end of the two sliding rods 705. A cutting blade 707 is fixedly installed on one side of the fixing plate 706. The cutting blade 707 is located below the pressure roller 602 and corresponds to the position of the cutting groove 9. A connecting plate 708 is fixedly installed at the other end of the two slide rods 705. A connecting rod 709 is rotatably connected to the outer surface of the connecting plate 708. One end of the connecting rod 709 is rotatably connected to the lower surface of one end of the turntable 703. Specifically, the third motor 702 drives the turntable 703 to rotate, and pushes the connecting plate 708 through the connecting rod 709, causing the slide bar 705 to slide back and forth in the sliding sleeve 704, thereby driving the cutting blade 707 on the fixed plate 706 to reciprocate cutting at the cutting groove 9, cutting the pre-compressed raw material into short segments, and the cut raw material falls into the crushing mechanism 5 area.

[0020] The crushing mechanism 5 includes a first rotating shaft 501, which is fixedly installed inside the housing 2 and the number of the first rotating shaft 501 is fixedly two.

A first gear 504 is fixedly installed on the outer surface of one end of the first rotating shaft 501. The two first gears 504 are meshed with each other. Specifically, the first motor 503 drives the first rotating shaft 501 to drive the crushing blade 502 to rotate at high speed. At the same time, the two first gears 504 mesh to ensure that the two shafts rotate in opposite directions, thereby achieving efficient crushing of the raw materials. Finally, the crushed material is discharged through the discharge port 4, completing the entire processing flow.

[0021] Working principle: In use, the plastic rattan is first fed into the housing 2 through the feeding port 3. It first passes through the pre-compression mechanism 6. When the pre-compression mechanism 6 is activated, the second motor 604 drives the second rotating shaft 601 to drive the two pressure rollers 602 to rotate in opposite directions, which initially flattens and arranges the plastic rattan raw material, making it more evenly enter the next process. Subsequently, the cutting mechanism 7 works. The third motor 702 drives the turntable 703 to rotate, which pushes the connecting plate 708 through the connecting rod 709, causing the slide bar 705 to slide back and forth in the sliding sleeve 704. This drives the cutting blade 707 on the fixed plate 706 to reciprocate and cut at the cutting groove 9, cutting the pre-compressed raw material into short segments. The cut raw material falls into the crushing mechanism 5 area. The first motor 503 drives the first rotating shaft 501 to drive the crushing blade 502 to rotate at high speed. At the same time, the two first gears 504 mesh to ensure that the two shafts rotate in opposite directions, realizing efficient crushing of the raw material. Finally, the crushed material is discharged through the discharge port 4, completing the entire processing process.
