Description

Technical Field

[0001] The present invention relates to a drip head sorting device, and in particular to an inlaid patch type drip head sorting device for drip irrigation tapes. Background Art

[0002] The inlaid patch type drip irrigation tape is an efficient irrigation tool. The inlaid patch type drip irrigation tape inlays the water dripping element (drip head) into the pipe and punches holes in the pipe. The impurities in the water are filtered through the filter window of the drip head, and it has good anti-blocking performance. The drip head is an important water control unit of the drip irrigation tape. At present, the drip head is produced by an injection molding method. The injection molding machine injects the melted liquid plastic into the drip head mold, and the liquid plastic cools and solidifies in the mold to form a solid drip head and a material handle with certain strength and toughness. Then, the drip head and the material handle are pushed out of the mold by the ejection device, fall into the hopper, and then the material handle is manually screened out for recycling, and the remaining finished drip heads are packaged and stored.

[0003] At present, the manual sorting of the drip head and the material handle not only increases the enterprise's investment in labor costs, is time-consuming and laborious, but also has the problem of incomplete sorting. The sorting quality is difficult to guarantee, seriously reducing the production efficiency of the drip head and affecting the production of the subsequent inlaid drip irrigation tape. Summary of the Invention

Embodiment 1

[0017] Refer to Figures 1 to 3The present invention provides a drip irrigation tape dripper sorting device, comprising a sorting roller 1, a transmission device, a dripper receiving hopper 2, a feeding hopper 3, a material handle discharge hopper 4 and a frame 5. The sorting rollers 1 are arranged in parallel with each other in a plurality of intervals (for example, four). Baffles 6 are arranged around the sorting roller 1 to prevent the dripper and the material handle from falling. The two ends of the sorting roller 1 are fixed to the sorting area on the top of the frame 5 through the first shaft seat bearing 7, one end of which is connected to the transmission device. The dripper receiving hopper 2 is fixed below the sorting roller 1. The dripper receiving hopper 2 is fixed to the bottom of the sorting roller 1. The hopper is funnel-shaped, and the drippers falling from the drop port of the sorting roller enter the dripper receiving hopper and are then sent to the collection device. The feeding hopper 3 and the material handle discharge hopper 4 are both integrated with the baffle 6. The feeding hopper is located on the right side of the sorting roller 1 on the far right, and the material handle discharge hopper 4 is located at the end of all the sorting rollers 1 away from the transmission device. The material handle discharge hopper is tilted downward (the feed port is higher than the discharge port position), and its feed port position is lower than the top of the sorting roller. The material handles sorted by the sorting rollers slide from the material handle discharge hopper into the material handle collection box.

[0018] See Figure 5 Each of the sorting rollers 1 includes a roller body 1-1, a spiral sheet 1-2, a rotating shaft 1-3 and a sorting roller sprocket 1-4. The spiral sheet 1-2 is spirally fixed to the outer surface of the roller body 1-1. The spiral direction of the spiral sheets 1-2 on all the sorting rollers 1 is the same (such as left-handed spiral sheets). The rotating shaft 1-3 axially passes through the center of the roller body 1-1, and both ends are fixed to the top of the frame 5 through the first shaft seat bearing 7. The sorting roller sprocket 1-4 is fixed to one end of the rotating shaft 1-3 and is located on the outside of the first shaft seat bearing 7. The sorting roller sprocket is connected to the transmission device.

[0019] The transmission device includes a motor 8, a main transmission shaft 9, a main transmission shaft sprocket 10, a transmission chain 11, a main transmission shaft pulley 12 and a motor pulley 13. The motor 8 is fixed to the frame 5, and the motor pulley 13 is fixed to the output shaft of the motor 8. The two ends of the main transmission shaft 9 are fixed to the top of the frame 5 through the second shaft seat bearing 14 and are located on the left side of the sorting roller 1. The main transmission shaft sprocket 10 and the main transmission shaft pulley 12 are respectively fixed to the two ends of the main transmission shaft 9 and are both located on the outside of the second shaft seat bearing 14. The main transmission shaft pulley 12 is connected to the motor pulley 13 through a belt. The main transmission shaft sprocket 10 is connected to several of the sorting roller sprockets 1-4 arranged in parallel through a transmission chain 11. Several sorting rollers are connected to the same main transmission shaft sprocket through the same chain to ensure that all sorting rollers rotate synchronously to avoid material jamming.

[0020] See Figure 4, the pitch L of the spiral fins on each sorting roller 1 is greater than the width B2 of the drip head 20. The spiral fins 1-2 on two adjacent sorting rollers 1 are arranged alternately. The gap between two alternately arranged spiral fins 1-2 is the material dropping port. The width B1 of the material dropping port is greater than the width B2 of the drip head, and the distance D1 between the front and rear spiral fins is greater than the thickness D2 of the drip head. Any two groups of sorting rollers are adjacent to each other. By adjusting the distance between the sorting rollers and the pitch of the spiral fins, it is possible to be applicable to the sorting of drip heads of different sizes. Embodiment 2

[0021] Based on Embodiment 1, a drip head conveying device is further provided, which is arranged directly below the drip head receiving hopper and includes a conveyor belt 15, a front conveyor belt roller 16, a rear conveyor belt roller 17 and a front conveyor roller pulley 18. The conveyor belt 15 bypasses the front conveyor belt roller 16 and the rear conveyor belt roller 17 and is horizontally arranged directly below the drip head receiving hopper 2. The two ends of the rotating shafts on the front conveyor belt roller 16 and the rear conveyor belt roller 17 are respectively fixed to both ends of the frame 5 through third shaft seat bearings 19. The front conveyor roller pulley 18 is fixed to one end of the rotating shaft on the front conveyor belt roller 16. The main drive shaft pulley 12 is a double pulley, and the front conveyor roller pulley 18 is connected to the main drive shaft pulley 12 by a belt. The motor drives the main drive shaft and the front conveyor belt roller to rotate simultaneously, so as to realize the simultaneous selection and drip head conveying.

[0022] Sorting process: The mixture of drip heads and shanks produced by the injection molding machine falls onto the feeding hopper of this device. Due to the action of gravity, the mixture of drip heads and shanks will slide onto the sorting rollers. The motor drives the main drive shaft to rotate, and at the same time drives the sorting rollers and the conveyor belt to rotate (front view). Under the action of the spiral fins on the sorting rollers, due to the shape difference between the drip heads and the shanks, the drip heads fall from the material dropping ports between the spiral fins, while the shanks will be driven by the spiral fins to move to the other side and be concentrated into the shank discharge hopper, thus realizing the separation of the drip heads and the shanks. The separated drip heads fall onto the conveyor belt below the receiving hopper, and are conveyed to the designated position for collection by the conveyor belt, for use in the production of drip irrigation tapes in the next process. The shanks fall into the collection container from the shank discharge hopper on the other side. After being centrally collected and processed, they can continue to be used as materials for drip head production. The entire sorting process has a high degree of automation and does not require manual participation, greatly improving the sorting efficiency and quality, and reducing the production cost. In addition, by adjusting the distance between the sorting rollers and the pitch of the spiral fins, it is possible to adapt to the sorting requirements of drip heads of different sizes, enhancing the applicability and flexibility of the present invention.
