Description

Technical Field

[0001] This utility model relates to a dripper sorting device, and more particularly to a sorting device for embedded patch drippers suitable for drip irrigation tape. Background Technology

[0002] In-line drip tape is a highly efficient irrigation tool. It integrates the dripping element (driver) into a tube with perforations, allowing impurities in the water to be filtered through the dripper's filter window, resulting in good anti-clogging performance. The dripper is a crucial water control unit of the drip tape. Currently, drippers are manufactured using injection molding. An injection molding machine injects molten liquid plastic into a dripper mold, where it cools and solidifies to form a solid dripper and stalk with a certain strength and toughness. An ejector then pushes the dripper and stalk out of the mold, into a hopper. The stalks are then manually sorted for recycling, while the remaining finished drippers are packaged and stored.

[0003] Currently, manually sorting drippers and drip trays not only increases the company's labor costs, is time-consuming and labor-intensive, but also has the problem of incomplete sorting, making it difficult to guarantee sorting quality, which seriously reduces the production efficiency of drippers and affects the subsequent production of drip irrigation tape. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a sorting device suitable for drip irrigation tape drippers, which can automatically separate the dripper and the material handle, resulting in high sorting efficiency and more accurate sorting.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A sorting device for drip irrigation tape emitters includes sorting rollers, a transmission device, an emitter receiving hopper, a feeding hopper, a stalk discharge hopper, and a frame. Several sorting rollers are arranged side-by-side at intervals. Each sorting roller is surrounded by baffles. Both ends of each sorting roller are fixed to the sorting area at the top of the frame via first bearing seats, with one end connected to the transmission device. The emitter receiving hopper is fixed below the sorting rollers. The feeding hopper and the stalk discharge hopper are integrally formed with the baffles. The feeding hopper is located to the right of the rightmost sorting roller, and the stalk discharge hopper is located at the end of all the sorting rollers furthest from the transmission device.

[0007] The above-described sorting device for drip irrigation tape emitters includes a sorting roller comprising a roller body, a spiral blade, a rotating shaft, and a sorting roller sprocket. The spiral blade is spirally fixed to the outer surface of the roller body, and the spiral blades on all sorting rollers have the same spiral direction. The rotating shaft passes axially through the center of the roller body, and its two ends are respectively fixed to the top of the frame by the first bearing seat. The sorting roller sprocket is fixed to one end of the rotating shaft, located outside the first bearing seat.

[0008] The above-described sorting device for drip irrigation tape emitters includes a transmission device comprising a motor, a main drive shaft, a main drive shaft sprocket, a transmission chain, a main drive shaft pulley, and a motor pulley. The motor is fixed to the frame, and the motor pulley is fixed to the output shaft of the motor. The two ends of the main drive shaft are fixed to the top of the frame via second bearing seats and are located to the left of the sorting roller. The main drive shaft sprocket and the main drive shaft pulley are respectively fixed to the two ends of the main drive shaft, both located outside the second bearing seats. The main drive shaft pulley is connected to the motor pulley via a belt, and the main drive shaft sprocket is connected to the sorting roller sprocket via the transmission chain.

[0009] The above-mentioned sorting device for drip irrigation tape drippers has a screw pitch L on each sorting roller that is greater than the width B2 of the dripper. The screws on two adjacent sorting rollers are alternately arranged, and the gap between the two alternate screws is the discharge port. The width B1 of the discharge port is greater than the width B2 of the dripper, and the distance D1 between the front and rear screws is greater than the thickness D2 of the dripper.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model achieves automatic separation of the dripper and the material handle by driving the rotation of the main drive shaft and the sorting roller assembly by a motor, without the need for manual intervention, which greatly improves the sorting efficiency and sorting quality.

[0012] 2. The sorting roller assembly consists of several sorting rollers. Both ends of the sorting rollers are mounted on the frame through bearing seats. Each sorting roller assembly consists of a roller body and a spiral blade sleeved on the roller body. By adjusting the spacing between the sorting rollers and the pitch of the spiral blades, it can adapt to the sorting requirements of different sized droppers, thus enhancing the applicability and flexibility of this utility model.

[0013] 3. After separation, the drippers fall into the dripper receiving hopper for collection and are used in the production of drip irrigation tape in the next process. The stalks, on the other hand, fall from the stalk outlet hopper at one end of the sorting roller into a collection container. After collection and processing, they can be used as material for dripper production. The entire device is scientifically designed and rationally structured, achieving efficient collection and transportation of drippers and stalks. Attached Figure Description

[0023] See Figures 1 to 3This utility model discloses a sorting device for drip irrigation tape emitters, comprising a sorting roller 1, a transmission device, an emitter receiving hopper 2, a feeding hopper 3, a feed handle discharge hopper 4, and a frame 5. Several sorting rollers 1 are arranged side-by-side at intervals (e.g., four). Baffles 6 are provided around the sorting rollers 1 to prevent emitters and feed handles from falling off. Both ends of the sorting rollers 1 are fixed to the sorting area at the top of the frame 5 via first bearing seats 7, with one end connected to the transmission device. The emitter receiving hopper 2 is fixed below the sorting rollers 1. The head receiving hopper is funnel-shaped. The drippers falling from the discharge port of the sorting roller enter the dripper receiving hopper and fall into the collection device. The feeding hopper 3 and the material handle discharge hopper 4 are both integrally set with the baffle 6. The feeding hopper is located to the right of the rightmost sorting roller 1. 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 inclined downward (the inlet is higher than the outlet position). Its inlet position is lower than the top of the sorting roller. The material handles 16 after being sorted by the sorting roller slide down from the material handle discharge hopper into the material handle collection box.

[0024] See Figure 5 Each sorting roller 1 includes a roller body 1-1, a spiral blade 1-2, a rotating shaft 1-3, and a sorting roller sprocket 1-4. The spiral blade 1-2 is spirally fixed to the outer surface of the roller body 1-1. The spiral direction of the spiral blades 1-2 on all sorting rollers 1 is the same (e.g., left-hand spiral blade). The rotating shaft 1-3 passes axially through the center of the roller body 1-1, and its two ends are respectively fixed to the top of the frame 5 by the first bearing seat 7. The sorting roller sprocket 1-4 is fixed to one end of the rotating shaft 1-3 and is located outside the first bearing seat 7. The sorting roller sprocket is connected to the transmission device.

[0025] The transmission device includes a motor 8, a main drive shaft 9, a main drive shaft sprocket 10, a transmission chain 11, a main drive 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 drive shaft 9 are fixed to the top of the frame 5 via second bearing seats 14 and are located to the left of the sorting rollers 1. The main drive shaft sprocket 10 and the main drive shaft pulley 12 are respectively fixed to the two ends of the main drive shaft 9, both located outside the second bearing seats 14. The main drive shaft pulley 12 is connected to the motor pulley 13 via a belt. The main drive shaft sprocket 10 is connected to several sorting roller sprockets 1-4 arranged in parallel via a transmission chain 11. Several sorting rollers are connected to the same main drive shaft sprocket via the same chain, ensuring that all sorting rollers rotate synchronously and avoiding material jamming.

[0026] See Figure 4The pitch L of the spiral blades on each sorting roller 1 is greater than the width B2 of the dripper 15. The spiral blades 1-2 on two adjacent sorting rollers 1 are alternately arranged, and the gap between two alternating spiral blades 1-2 is the discharge port. The width B1 of the discharge port is greater than the width B2 of the dripper, and the distance D1 between two spiral blades is greater than the thickness D2 of the dripper. Any two sorting rollers are arranged adjacently. By adjusting the distance between the sorting rollers and the pitch of the spiral blades, it is possible to sort drippers of different sizes.

[0027] Sorting Process: The mixture of drippers and stalks produced by the injection molding machine falls onto the feeding hopper of this device. Due to gravity, the mixture slides onto the sorting roller. The motor drives the main drive shaft to rotate, simultaneously rotating the sorting roller (main view). Under the action of the spiral blades on the sorting roller, due to the difference in shape and size between the drippers and stalks, the drippers fall from the discharge port between the spiral blades, while the stalks are moved to the other side by the spiral blades and collected in the stalk discharge hopper, thus achieving the separation of drippers and stalks. The separated drippers fall into the collection container from the receiving hopper for use in the next process of drip tape production. The stalks fall into the collection container from the stalk discharge hopper on the other side, and after collection and processing, can continue to be used as material for dripper production. The entire sorting process is highly automated, requiring no manual intervention, greatly improving sorting efficiency and quality, and reducing production costs. Furthermore, by adjusting the spacing between the sorting rollers and the pitch of the spiral blades, the sorting requirements of different sized droppers can be met, enhancing the applicability and flexibility of this invention.
