Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a plastic particle conveying and unloading equipment for power pipeline production. Background Art

[0002] Recycled plastic granules are often used in the production of power pipes. These granules are formed by recycling used new materials or discarded plastic products and processing them. They are then packaged into bags and transported to factories for the manufacture of power pipes. Power pipes are made by extruders that heat and extrude recycled plastic granules, so it is necessary to use conveying equipment to transport the recycled plastic granules to the extruder.

[0003] In the production of power pipelines, screw feeders are commonly used in the industry to transport recycled plastic granules to the extruder. The current operating process relies on manual intervention: workers need to manually lift the packaging bags containing plastic granules above the hopper of the screw feeder and use a blade to cut the bag open so that the granules inside fall into the hopper. The screw feeder then transports these granules to the extruder. However, in the process of cutting the bag open with a blade, it is easy for the bag debris to mix with the plastic granules. Traditional screw feeders lack the function of cleaning these debris, resulting in the bag debris mixed in the plastic granules being fed into the extruder, which may have a negative impact on the quality of the power pipeline finally produced.

[0034] See also Figure 7-Figure 8, a lifting and loading mechanism is provided on the frame 1, and the lifting and loading mechanism includes a Z-axis movable platform 61 connected to the left side of the frame 1, and a lifting plate 62 for lifting the packaging bag is connected to the Z-axis movable platform 61, and the lifting plate 62 can be driven to rise and fall through the Z-axis movable platform 61, and the Z-axis movable platform 61 is a prior art and will not be described in detail here. A rotating roller 11 is provided at the top of the lifting plate 62 from left to right in an interval manner, and the front and rear sides of the top of the frame 1 are connected to an X-axis movable platform 63, and a blocking plate 64 is connected between the left sides of the slide rails of the two X-axis movable platforms 63. A movable plate 65 is connected to the slider of the X-axis movable platform 63, and the movable plate 65 can be driven to reciprocate left and right through the X-axis movable platform 63. The X-axis movable platform 63 is a prior art and will not be described in detail here. The two movable plates 65 are close to each other. A lifting plate 66 is provided on the upper part of one side in a sliding manner through a slide groove, and a screw motor 67 is provided on the upper part of the movable plate 65. The screw on the screw motor 67 is threadedly connected to the lifting plate 66 on the same side. The bottom of the lifting plate 66 is connected with insertion rods 68 for inserting into the packaging bag at intervals from left to right. The bottom end of the insertion rod 68 is sharp and can smoothly insert the packaging bag. The lower part of the side where the two movable plates 65 are close to each other is connected with a support plate 69 for holding the packaging bag. The left side of the support plate 69 is connected with a wedge-shaped top block 610 for lifting the packaging bag. The side where the two movable plates 65 are close to each other is connected with a baffle 611, which is located between the lifting plate 66 and the support plate 69. Through holes 612 matching the insertion rod 68 are spaced from left to right on the baffle 611 and the support plate 69 for the insertion rod 68 to move up and down.

[0035] See also Figure 7-Figure 9 A cutting mechanism for cutting the packaging bag is provided at the upper front side of the frame 1, and the cutting mechanism includes an electric push rod 71 installed at the upper front side of the frame 1, a connecting block 73 is connected to the telescopic rod of the electric push rod 71, and a cutting knife 74 for cutting the packaging bag is connected to the top of the connecting block 73. The frame 1, the hopper 2, the movable plate 65 and the support plate 69 are all provided with a through hole 75 for the connecting block 73 and the cutting knife 74 to slide forward and backward. The upper front side of the frame 1 is symmetrically slidably connected with two sliding rods 72 with the electric push rod 71 as the symmetry center. The rear end of the sliding rod 72 is connected to the connecting block 73 to guide the forward and backward movement of the connecting block 73.

[0036] First, place the packaging bag containing recycled plastic particles on the lifting plate 62, then control the Z-axis moving platform 61 to drive the lifting plate 62 to move upward to lift the packaging bag, and then control the X-axis moving platform 63 to drive the movable plate 65 to move leftward, thereby driving the insertion rod 68, the supporting plate 69 and the wedge-shaped top block 610 to move leftward. When the wedge-shaped top block 610 moves leftward until it contacts the packaging bag, the wedge-shaped top block 610 continues to move leftward through its upper inclined surface to lift the packaging bag upward, so as to ensure that the supporting plate 69 can smoothly move leftward to the lower side of the packaging bag and lift the packaging bag. The blocking plate 64 can block the limited packaging bag to prevent the packaging bag from being pushed leftward by the supporting plate 69 and sliding off the lifting plate 62, so as to ensure that the packaging bag can be smoothly lifted upward by the supporting plate 69. Then, the screw motor 67 is controlled to rotate to drive the lifting plate 66 to drive the insertion rod 68 to move downward to pierce the packaging bag. Subsequently, the X-axis moving platform 63 is controlled to drive the movable plate 65 to move to the right, thereby driving the packaging bag to move to the right to the top of the hopper 2 and aligning with the cutting knife 74 through the support plate 69 and the insertion rod 68. The friction between the lifting plate 62 and the packaging bag can be reduced by the rotating roller 11, which helps the insertion rod 68 to smoothly pull the packaging bag to the right and separate it from the lifting plate 62. At the same time, the Z-axis moving platform 61 is controlled to drive the lifting plate 62 to move downward in preparation for lifting the next packaging bag. After the packaging bag is aligned with the cutting knife 74 to the right, the electric push rod 71 is controlled to drive the connecting block 73 to move back and forth with the cutting knife 74. The cutting knife 74 moves backward to cut the bottom of the packaging bag, and the recycled plastic particles in the packaging bag fall into the hopper 2. In this way, the equipment can automatically lift the packaging bag and move it to the top of the hopper 2 through the lifting and feeding mechanism, and can automatically cut the packaging bag through the cutting mechanism. There is no need for manual lifting and cutting of the packaging bag, which improves the degree of automation, reduces labor intensity, and thus improves work efficiency.

[0037] The plastic particles in the hopper 2 then fall into the discharge channel 4, and are guided to the opening 511 by the guide plate 512. The plastic particles then enter the drum 51, and the air pump 52 is controlled to work to inject gas into the drum 51 through the air pipe 53. Under the blowing action of the airflow, the bag debris and dust mixed in the plastic particles are blown backwards into the discharge pipe 56, and then the bag debris and dust are discharged backwards into the cloth bag 59 through the connecting pipe 58 for collection, achieving the effect of effectively removing the bag debris and dust mixed in while conveying the plastic particles, thereby improving the quality of the power pipeline. Since the discharge pipe 56 is installed with a high front and a low back, the diameter of the discharge pipe 56 gradually decreases from the front to the back, so that the plastic particles can be blocked, so that the plastic particles blown into the discharge pipe 56 flow back into the drum 51 to avoid waste. The plastic particles after impurity removal are then discharged through the downward opening 511 on the rotating drum 51, and the plastic particles then enter the screw feeder 3, and are finally transported to the extruder by the screw feeder 3. The drive motor 54 is controlled to work, and the rotating drum 51 can be driven to rotate through the gear set 55. The rotating drum 51 can realize intermittent feeding through the opening 511 thereon to avoid excessive feeding affecting the efficiency and effect of impurity removal, so as to improve the efficiency and effect of impurity removal. After all the plastic particles in the packaging bag fall into the hopper 2, the screw motor 67 is controlled to reverse to drive the lifting plate 66 to drive the insertion rod 68 to move up and reset. The baffle 611 can block the empty packaging bag to push the empty packaging bag off the insertion rod 68 to avoid the empty packaging bag being stranded on the insertion rod 68, so as to facilitate the subsequent removal of the empty packaging bag. When it is necessary to clean the impurities in the cloth bag 59, the rubber band 510 is manually stretched and separated from the connecting tube 58, and then the cloth bag 59 can be removed from the connecting tube 58 to facilitate cleaning of the impurities in the cloth bag 59. After the impurities are cleaned, the cloth bag 59 is re-fixed on the connecting tube 58 by the rubber band 510. The operation of loading and unloading the cloth bag 59 is simple, convenient and fast, which can prevent impurities from flying around, so as to protect the working environment and the health of workers.

[0038] See also Figure 4 and Figure 6The unloading channel 4 is provided with an unblocking mechanism for unblocking the discharge port of the hopper 2. The unblocking mechanism includes two guide sleeves 81 respectively connected to the upper parts of the inner walls on both sides of the unloading channel 4. The guide sleeve 81 is located above the rotating drum 51 and between the two guide plates 512. A wedge block 83 is slidably connected in the guide sleeve 81. The rotating drum 51 can contact the inclined surface of the wedge block 83 and push the wedge block 83 upward when rotating. A unblocking rod 82 is connected to the top of the wedge block 83. The top of the unblocking rod 82 extends into the hopper 2. The top of the unblocking rod 82 A conical dredging block is connected to increase the dredging area and improve the dredging efficiency and effect. The dredging rod 82 is sleeved with a spring 85 located in the guide sleeve 81. The two ends of the spring 85 are respectively connected to the top of the wedge block 83 and the inner top of the guide sleeve 81. A telescopic sleeve 84 is connected between the top of the guide sleeve 81 and the dredging rod 82 to seal the gap between the guide sleeve 81 and the dredging rod 82 to prevent plastic particles from entering the guide sleeve 81 and causing blockage, ensuring that the inside of the guide sleeve 81 is unobstructed, thereby ensuring that the dredging rod 82 can perform dredging operations normally.

[0039] When the rotating drum 51 rotates to contact the inclined surface on the right side of the wedge block 83, the rotating drum 51 continues to rotate to push the wedge block 83 upward, compressing the spring 85. When the opening 511 on the rotating drum 51 rotates to align with the wedge block 83, under the restoring action of the spring 85, the wedge block 83 is pushed downward and reset, and the cycle is repeated. The wedge block 83 can drive the dredging rod 82 to move up and down, thereby realizing automatic dredging of the discharge port of the hopper 2, effectively avoiding blockage of the hopper 2, thereby maintaining the continuity and efficiency of the discharge process.

[0040] See also Fig.10 A knocking mechanism for knocking the packaging bag is provided in the opening 75 on the movable plate 65, and the knocking mechanism includes an electric rotating rod 91 arranged in the opening 75 on the movable plate 65. The electric rotating rod 91 includes a small motor and a rotating shaft.

The rotating shaft is connected to the output shaft of the small motor, and a knocking plate 92 for knocking the packaging bag is connected to the rotating shaft. A buffer pad located directly above the knocking plate 92 is connected to the bottom of the baffle 611, and the baffle 611 and the knocking plate 92 can be buffered and protected by the buffer pad to prevent the knocking plate 92 from being directly damaged by collision with the baffle 611, thereby extending the service life of the baffle 611 and the knocking plate 92.

[0041] The electric rotating rod 91 is controlled to drive the knocking plate 92 to swing back and forth downward and upward. The knocking plate 92 can knock the packaging bag when it swings downward, causing the packaging bag to vibrate and shake the plastic particles inside it into the hopper 2, thereby preventing the plastic particles from being retained in the packaging bag due to static friction and the like, and enabling the plastic particles to be transferred from the packaging bag to the hopper 2 as much as possible to reduce waste.

[0042] See also Figure 1 and Fig.11 A bag taking mechanism is provided at the upper right side of the frame 1, and the bag taking mechanism includes a mounting frame 101 connected to the upper right side of the frame 1, and two electric push rods 102 are symmetrically installed on the mounting frame 101 with the screw feeder 3 as the symmetry center. A finger cylinder 103 for clamping the packaging bag is installed on the telescopic rod of the electric push rod 102, and a conveyor belt 104 located at the lower side of the finger cylinder 103 is provided on the mounting frame 101.

[0043] After the insertion rod 68 moves up and disengages from the packaging bag, the electric push rod 102 is controlled to drive the finger cylinder 103 to move to the left to approach the packaging bag, and then the two claws on the finger cylinder 103 are controlled to move closer to each other to clamp the packaging bag. Subsequently, the electric push rod 102 is controlled to drive the finger cylinder 103 to move to the right, thereby moving the packaging bag to the right onto the conveyor belt 104. Finally, the two claws on the finger cylinder 103 are controlled to move away from each other to release the packaging bag. The packaging bag is then transported backwards by the conveyor belt 104, and there is no need for manual bag removal, which further improves the degree of automation, further reduces labor intensity, and can further improve work efficiency.
