[0002] During the processing of plastic raw materials, plastic raw material molding equipment is needed to cut the plastic raw material strips into granules, and then receiving equipment is used to collect the granules. However, in actual use, the existing plastic raw material receiving equipment still has the following shortcomings: First, in order to adapt to the dynamic granulation requirements, eliminate material accumulation, and improve the granulation rate, different models of plastic raw material molding equipment have different discharge port positions, including vertical discharge ports and inclined discharge ports at 15-60°. However, the inlet position of the existing plastic raw material receiving equipment is constant and cannot be adapted to use with both vertical and inclined discharge ports, resulting in poor applicability. Second, since crushed material, powder, and other scraps are inevitably generated during the cutting of plastic raw material strips, the existing plastic raw material receiving equipment cannot screen out crushed material, powder, and other scraps in the plastic raw materials during the receiving process. Therefore, a separate screening device is required to remove them, which increases production costs and extends the processing cycle of plastic raw materials. Utility Model Content

Detailed Implementation
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-station plastic raw material receiving device includes a base 1, a receiving box 2 disposed on the base 1, a screen tube 3 with one end extending into the receiving box 2, a feed pipe 4 disposed at the top of the receiving box 2, an angle adjustment mechanism 5 for adjusting the feeding direction of the feed pipe 4, the bottom end of the feed pipe 4 being connected to the screen tube 3, the screen tube 3 having a plurality of screen holes 31 radially opened on it, the screen tube 3 being provided with a spiral feeding mechanism, and the screen tube 3 having a discharge port 32 after extending out of the receiving box 2.
[0021] In use, the feeding direction of the feed pipe 4 is adjusted by the angle adjustment mechanism 5, making it suitable for use in plastic raw material molding equipment with inclined and vertical discharge ports. During the process of the spiral feeding mechanism driving the plastic raw material particles to move in the screen pipe 3, the crushed material, powder and other scraps pass through the screen holes 31 on the screen pipe 3 and enter the receiving box 2. The screened plastic raw material is discharged through the discharge port 32. This utility model is applicable to plastic raw material molding equipment with both inclined and vertical discharge ports, with better applicability. It can also automatically screen out crushed material, powder and other scraps in the plastic raw material, eliminating the need for separate screening equipment, reducing production cost investment, and shortening the processing cycle of plastic raw materials.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the feed pipe 4 includes an inlet pipe 41, a telescopic corrugated pipe 42, and an outlet pipe 43. The inlet pipe 41 is installed at the output end of the angle adjustment mechanism 5, and the bottom end of the outlet pipe 43 is fixed in the receiving box 2. The top end of the outlet pipe 43 and the bottom end of the inlet pipe 41 are connected by the telescopic corrugated pipe 42. In this embodiment, the angle of the inlet pipe 41 is adjusted by the angle adjustment mechanism 5, and the telescopic corrugated pipe 42 deforms, so that the plastic raw material particles entering the inlet pipe 41 can always be discharged from the outlet pipe 43.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the angle adjustment mechanism 5 includes a back plate 51 fixed to the top of the receiving box 2, an adjustment plate 52 rotatably connected to the bottom of the back plate 51, a U-shaped groove 53 fixed to the back plate 51, a slider 54 slidably connected to the U-shaped groove 53, an adjustment motor 55 fixed at the opening of the U-shaped groove 53, a lead screw 56 driven by the output shaft of the adjustment motor 55, an internal threaded hole on the slider 54 opposite to the lead screw 56, and through grooves 531 symmetrically arranged on the vertical part of the U-shaped groove 53, with a sliding connection within the through groove 531. A sliding column 57 is provided, with one end fixed to a slider 54 and the other end rotatably connected to a connecting rod 58. The end of the connecting rod 58 away from the sliding column 57 is rotatably connected to the adjusting plate 52. The inlet pipe 41 is fixed to the adjusting plate 52. In this embodiment, during the rotation of the lead screw 56 driven by the adjusting motor 55, the lead screw 56 drives the slider 54 to slide along the slider 54 through the internal threaded hole. The slider 54 adjusts the pitch angle of the adjusting plate 52 through the sliding column 57 and the connecting rod 58, thereby adjusting the pitch angle of the inlet pipe 41 to make it suitable for use with inclined and vertical discharge ports.
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the inlet pipe 41 is provided with a funnel-shaped feed port; in this embodiment, the funnel-shaped feed port makes it easier for the top of the inlet pipe 41 to abut against the discharge port of different models of plastic raw material molding equipment.

The conveying motor 62 drives the rotating shaft 61, and a spiral feeding channel is formed between the rotating shaft 61, the conveying vane 63, and the inner wall of the screen tube 3. In this embodiment, plastic raw material particles enter the spiral feeding channel through the feed pipe 4. The conveying motor 62 drives the rotating shaft 61 to rotate the conveying vane 63, so that the plastic raw material particles are conveyed along the spiral feeding channel to the discharge port 32. The crushed material, powder, and other scraps in the conveying process are screened out through the screen holes 31 on the screen tube 3. No additional screening equipment is required, which reduces production cost and shortens the processing cycle of plastic raw materials.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, four cylinders 7 are equidistantly arranged on the base 1. The cylinders 7 are fixed on the base 1, and the piston rod head of the cylinder 7 extends vertically upward to drive the material receiving box 2. In this embodiment, the feeding height of the feed pipe 4 can be adjusted by extending and retracting the piston rod head of the cylinder 7, which improves its applicability.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the receiving box 2 has an opening on one side, and a pull-out drawer 8 is provided at the opening. In this embodiment, the crushed material, powder, and other scraps that are screened out by the screen tube 3 fall into the pull-out drawer 8 under the action of gravity. Pulling out the drawer 8 makes it easier to take out the crushed material, powder, and other scraps.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a controller 9 installed on one side of the receiving box 2. The angle adjustment mechanism 5 and the screw feeding mechanism are both electrically connected to the controller 9. In this embodiment, the angle adjustment mechanism 5 and the screw feeding mechanism can be adjusted by the controller 9.
