Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe technology, and in particular to a raw material screening device for the production of PE water supply pipes. Background Technology

[0002] PE water supply pipes are water pipes injection molded from polyethylene as raw material. They have the characteristics of high strength and corrosion resistance. Different particle sizes of polyethylene raw materials are used to produce different types of PE water supply pipes, which need to be screened and distinguished before production.

[0003] Screening is required when producing different types of PE water supply pipes. However, polyethylene raw material particles are often of inconsistent size, which means that the screens of the screening device need to be replaced before adding raw materials. The larger diameter raw material particles left after screening also need to be removed from the screen, which is time-consuming and labor-intensive. In addition, some horizontal screens cannot fully screen polyethylene raw material particles according to their diameter, and secondary screening is required. This has certain limitations in actual use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material screening device for the production of PE water supply pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A raw material screening device for PE water supply pipe production includes a support frame and a first motor. An inclined mounting frame is fixedly installed on the top of the support frame, and the first motor is fixedly installed on the lower side wall of the mounting frame via a bracket. The output shaft of the first motor is fixedly connected to a rotating block, and a screening mechanism including an annular rotating block is provided on one side of the rotating block. The rotating block is fixedly connected to an inclined annular rotating block on the side away from the first motor. A spiral ring is movably arranged on the inner wall of the annular rotating block. The end of the annular rotating block is rotatably connected to the higher side wall of the mounting frame. The annular rotating block has several large holes on the side close to the first motor and several small holes on the side away from the first motor.

[0006] Preferably, the bottom end of the support frame is fixedly installed on the base, and two collection boxes are movably installed on the top end of the base.

[0007] Preferably, the mounting bracket has a feed inlet fixedly installed at the end away from the first motor, and the bottom of the feed inlet is connected to the annular rotating block.

[0008] Preferably, a first discharge port is fixedly installed on the bottom side of the mounting frame away from the first motor, and a second discharge port is fixedly installed on the bottom side of the mounting frame close to the first motor. The bottom openings of the first discharge port and the second discharge port correspond to two collection boxes, respectively.

[0009] Preferably, the top opening of the first discharge port corresponds to the small hole, and the top opening of the second discharge port corresponds to the large hole.

[0010] Preferably, a motor box is fixedly installed at the end of the rotating block away from the first motor, a second motor is fixedly installed inside the motor box, the output shaft of the second motor is fixedly connected to a rotating seat, four evenly distributed protrusions are fixedly connected to one side of the rotating seat, a sliding sleeve is slidably connected to the rotating seat on one side of the protrusions, four connecting rods are fixedly connected to the outer wall of the sliding sleeve, and the ends of the four connecting rods are fixedly connected to the inner wall of one side of the spiral ring.

[0011] Preferably, two electric telescopic rods are fixedly installed on both sides of the rotating seat, and the telescopic ends of the two electric telescopic rods are fixedly connected to the side wall of the sliding sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the setting of a screening mechanism, an inclined mounting frame, and an annular rotating block, allows polyethylene raw material particles to automatically flow downwards along the annular rotating block under the action of gravity. The screening mechanism, driven by a first motor, rotates the annular rotating block, thereby causing the polyethylene raw material particles to rotate. This allows the polyethylene raw material particles to be classified and collected according to their diameter, passing through small holes and large holes in sequence through the first and second discharge ports. This enables a batch of polyethylene raw material particles to be directly classified according to their diameter without the need for staff to change the screen. It also allows larger diameter polyethylene raw material particles to flow out through the large holes without the need for manual removal from the screen, saving manpower and simplifying the operation process.

[0013] This invention features a spiral ring. A second motor drives a rotating base to rotate in the opposite direction to the first motor. The rotating base, via a protrusion, drives the sliding sleeve, connecting rod, and spiral ring to rotate in the opposite direction. This causes the spiral ring to rotate in the opposite direction to the annular rotating block, facilitating the subsequent rotation and agitation of the polyethylene raw material particles. This allows for more thorough screening of the polyethylene raw material particles, preventing small particles from flowing into the large holes and preventing some particles from getting stuck in the small and large holes, thus affecting the screening process. When the second motor rotates, two electric telescopic rods are activated, causing the sliding sleeve and spiral ring to slide back and forth along the protrusion. This allows the spiral ring to reciprocate and push the polyethylene raw material particles while simultaneously agitating them in reverse, further achieving thorough screening of the polyethylene raw material particles.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-6 A raw material screening device for PE water supply pipe production includes a support frame 2 and a first motor 8. An inclined mounting frame 3 is fixedly installed on the top of the support frame 2. The first motor 8 is fixedly installed on the lower side wall of the mounting frame 3 through a bracket. The output shaft of the first motor 8 is fixedly connected to a rotating block 10. A screening mechanism 9 including an annular rotating block 11 is provided on one side of the rotating block 10. An inclined annular rotating block 11 is fixedly connected to the rotating block 10 on the side away from the first motor 8. A spiral ring 21 is movably arranged on the inner wall of the annular rotating block 11. The end of the annular rotating block 11 is rotatably connected to the higher side wall of the mounting frame 3. Several large holes 13 are opened on the side of the annular rotating block 11 close to the first motor 8, and several small holes 12 are opened on the side of the annular rotating block 11 away from the first motor 8. The inclined mounting frame 3 and the annular rotating block 11 allow the polyethylene raw material particles to flow automatically downward along the annular rotating block 11 under the action of gravity. The screening mechanism 9 drives the annular rotating block 11 to rotate through the first motor 8, thereby driving the polyethylene raw material particles to rotate. The polyethylene raw material particles are then classified and collected according to their diameter, passing through the small holes 12 and the large holes 13 in sequence through the first discharge port 5 and the second discharge port 6. This allows a batch of polyethylene raw material particles to be directly classified according to their diameter without the need for staff to change the screen. It also allows the larger diameter polyethylene raw material particles to flow out through the large holes 13 without the need for manual removal from the screen, saving manpower and simplifying the operation process.

[0018] As a technical optimization of this utility model, the bottom end of the support frame 2 is fixedly installed on the base 1, and two collection boxes 7 are movably installed on the top end of the base 1. The two collection boxes 7 are used to collect polyethylene raw material particles of different diameters.

[0019] As a technical optimization of this utility model, a feed inlet 4 is fixedly installed on the end of the mounting frame 3 away from the first motor 8, and the bottom of the feed inlet 4 is connected to the annular rotating block 11. The feed inlet 4 is used to inject polyethylene raw material particles to facilitate subsequent screening.

[0020] As a technical optimization of this utility model, a first discharge port 5 is fixedly installed on the bottom side of the mounting frame 3 away from the first motor 8, and a second discharge port 6 is fixedly installed on the bottom side of the mounting frame 3 close to the first motor 8. The bottom openings of the first discharge port 5 and the second discharge port 6 correspond to two collection boxes 7, respectively. The screened polyethylene raw material particles flow out through the first discharge port 5 and the second discharge port 6 according to their size for collection.

[0021] As a technical optimization of this utility model, the top opening of the first discharge port 5 corresponds to the small hole 12, and the top opening of the second discharge port 6 corresponds to the large hole 13. After being screened through the large hole 12 and the small hole 13, the materials are discharged and collected in batches for easy classification.

[0022] As a technical optimization of this utility model, a motor box 14 is fixedly installed at the end of the rotating block 10 away from the first motor 8. A second motor 15 is fixedly installed inside the motor box 14. The output shaft of the second motor 15 is fixedly connected to a rotating seat 16. Four evenly distributed protrusions 17 are fixedly connected to one side of the rotating seat 16. A sliding sleeve 18 is slidably connected to the rotating seat 16 on one side of the protrusions 17. Four connecting rods 20 are fixedly connected to the outer wall of the sliding sleeve 18. The ends of the four connecting rods 20 are fixedly connected to the inner wall of one side of the spiral ring 21. Before screening polyethylene raw material particles, the rotating block 10, motor box 14, rotating seat 16, and spiral ring 21 are driven by the first motor 8 to rotate. At this time, the second motor 15 is started to drive the rotating seat 16 to rotate in the opposite direction to the first motor 8. The rotating seat 16 drives the sliding sleeve 18, connecting rod 20, and spiral ring 21 to rotate in the opposite direction through the protrusion 17. This causes the spiral ring 21 to rotate in the opposite direction to the annular rotating block 11 on the inner wall of the annular rotating block 11. This facilitates the subsequent rotation of the polyethylene raw material particles while also agitating them, allowing the polyethylene raw material particles to move more fully and be screened more thoroughly. This prevents small polyethylene raw material particles from flowing out of the large hole 13 and also prevents some polyethylene raw material particles from getting stuck in the small hole 12 and the large hole 13, thus affecting the normal operation of the screening work.

[0023] As a technical optimization of this utility model, two electric telescopic rods 19 are fixedly installed on both sides of the rotating seat 16, and the telescopic ends of the two electric telescopic rods 19 are fixedly connected to the side wall of the sliding sleeve 18. When the second motor 15 rotates, the two electric telescopic rods 19 are activated to drive the sliding sleeve 18 and the spiral ring 21 to slide back and forth along the protrusion 17, so that the spiral ring 21 can push the polyethylene raw material particles back and forth while reversing and stirring, thereby further realizing the full screening of the polyethylene raw material particles.

[0024] In use, the first motor 8 is first started, which rotates the rotating block 10, causing the annular rotating block 11, motor box 14, and spiral ring 21 to rotate synchronously. Then, the second motor 15 is started, rotating in the opposite direction to the first motor 8. The second motor 15 rotates the rotating seat 16, protrusion 17, sliding sleeve 18, electric telescopic rod 19, and spiral ring 21 in the opposite direction to the annular rotating block 11. Simultaneously, the two electric telescopic rods 19 are started, causing them to cyclically extend and retract. This causes the sliding sleeve 18 to slide back and forth along the protrusion 17, which in turn causes the spiral ring 21 to rotate in the opposite direction while sliding back and forth along the inner wall of the annular rotating block 11. At this time, polyethylene... When polyethylene raw material particles are added to the feed inlet 4, the polyethylene raw material particles can flow into the annular rotating block 11. As the polyethylene raw material particles flow, the annular rotating block 11 rotates, and the spiral ring 21 stirs in the opposite direction, the smaller diameter polyethylene raw material particles will fall through the small hole 12 into the first discharge port 5 and flow into the collection box 7 below the first discharge port 5 for collection. However, the larger diameter polyethylene raw material particles cannot pass through the small hole 12. Under the stirring of the spiral ring 21 and the tilting state of the annular rotating block 11, the larger diameter polyethylene raw material particles gradually flow to the side of the large hole 13. At this time, the larger diameter polyethylene raw material particles will fall through the large hole 13 into the second discharge port 6 and flow into the collection box 7 below the second discharge port 6 for collection.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
