Description

Technical Field

[0001] This utility model relates to the field of ethylene-propylene copolymer granulation technology, and in particular to a granulation unit for ethylene-propylene copolymer modification. Background Technology

[0002] The granulation unit for ethylene propylene copolymer modification is a device used to process ethylene propylene copolymer (EPR) or its modified materials into granular products, and is widely used in the plastics, rubber and other industries.

[0003] When feeding ethylene-propylene copolymer raw materials, the raw materials themselves have certain fluidity differences and are affected by changes in ambient temperature and humidity, causing fluctuations in the bulk density of the raw materials. Traditional feeding structures cannot achieve real-time and precise control of the raw material feeding amount according to production process requirements. In addition, ethylene-propylene copolymer raw materials have a certain degree of viscosity, and during the feeding process, the raw materials easily adhere to key parts such as the feeding port, the inner wall of the conveying pipe, and the feeding valve. As the production process continues, the adhered raw materials will gradually accumulate, which will reduce the effective cross-sectional area of ​​the feeding channel, slow down the feeding speed, and even cause serious blockage problems, forcing production to be interrupted for manual cleaning. This not only reduces production efficiency but also increases the labor intensity of operators. Utility Model Content

[0035] Please see Figures 1-5 This utility model provides a granulation unit for modifying ethylene-propylene copolymer, including a granulation structure:

[0036] Feeding structure: The feeding structure is coaxially installed at the rear top of the granulation structure;

[0037] Granulation structure: The granulation structure includes a processing bed 11, an extruder 12, an inlet 13, a baffle 14, and a feed pipe 15;

[0038] The extruder 12 is fixedly connected to the top of the processing bed 11, the feeding port 13 is fixedly connected to the middle of the top of the extruder 12, the baffle 14 is fixedly connected to the outside of the front end of the extruder 12, and the feed pipe 15 is fixedly connected to the rear of the top of the extruder 12.

[0039] The granulation structure also includes a granulation tank 16 and an electric blade 17;

[0040] The granulation tank 16 is located at the front end of the extruder 12, and the electric blade 17 is rotatably connected to the middle of the front end of the granulation tank 16.

[0041] The feeding structure includes a feeding box 21, a feeding bin 22, a through slot 23, a protrusion 24, and a spring rod 25.

[0042] The feeding box 21 is fixedly connected to the top of the feeding pipe 15, the feeding bin 22 is fixedly connected to the top of the feeding box 21, the through groove 23 is opened on both sides of the outer wall of the feeding box 21, the protrusion 24 is rotatably connected to both sides of the outer wall of the feeding box 21, and the spring rod 25 is fixedly connected to one end of the protrusion 24.

[0043] The feeding structure also includes a transmission block 26, a storage box 27, a fixing block 28, a combination plate 29, an electric telescopic rod 210, and a feeding chute 211;

[0044] The transmission block 26 is fixedly connected to both sides of the outer wall of the feeding pipe 15, the storage box 27 is slidably connected to the inside of the feeding box 21, the fixing block 28 is fixedly connected to both ends of the storage box 27, the combination plate 29 is fixedly connected to the top of the storage box 27, the electric telescopic rod 210 is fixedly connected to the rear of the feeding box 21, and the feeding chute 211 is opened at the front end of the inside of the feeding box 21.

[0045] One side of the spring rod 25 is attached to the outside of the transmission block 26. The fixing block 28 passes through the outside of the feeding box 21 through the through slot 23. The feeding bin 22 and the storage box 27 are set on the same central axis. The storage box 27 and the discharge chute 211 are set on the same central axis. The connecting end of the electric telescopic rod 210 is fixedly connected to the storage box 27. The feeding box 21 is used to open the through slot 23.

[0046] With the auxiliary cooperation between the feeding box 21 and the feeding bin 22, when the storage box 27 slides inside the feeding box 21, the ethylene propylene copolymer raw material stored inside the storage box 27 can be discharged into the discharge pipe 15 through the discharge chute 211, and the spring rod 25 can repeatedly strike the transmission block 26.

[0047] Working principle: When the worker feeds the ethylene-propylene copolymer raw material;

[0048] First, the ethylene-propylene copolymer raw material is poured into the inside of the feeding hopper 22, which allows the ethylene-propylene copolymer raw material to be discharged into the inside of the storage box 27 through the feeding hopper 22. At the same time, the electric telescopic rod 210 is started to work, which allows the electric telescopic rod 210 to drive the storage box 27 to slide forward.

[0049] Next, when the storage box 27 slides above the discharge trough 211, the ethylene propylene copolymer raw material stored inside the storage box 27 can be discharged into the discharge pipe 15 through the discharge trough 211, and the combined plate 29 can block the discharge port of the feeding bin 22. At the same time, the fixed blocks 28 fixedly connected to both ends of the storage box 27 can squeeze the protrusion 24 through the through groove 23, thereby causing the spring rod 25 with the protrusion 24 fixedly connected to one end to rotate. When the storage box 27 is reset, the spring rod 25 can be reset under the influence of the elastic force and knock the outside of the transmission block 26. The vibration generated by the knocking can shake off the ethylene propylene copolymer raw material attached to the inner wall of the discharge pipe 15.

[0050] This step helps workers to uniformly feed the ethylene-propylene copolymer raw material while effectively preventing the raw material from adhering to the feeding point.

[0051] Please see Figure 2-5 As shown, this embodiment, based on the above embodiment, also includes a collection structure;

[0052] The collection structure includes a slide rail 31, a toothed block 32, a collection box 33, and a connecting groove 34;

[0053] The slide rail 31 is fixedly connected to the lower front end of the machining bed 11, the tooth block 32 is fixedly connected to both sides of the inner wall of the slide rail 31, the collection box 33 is slidably connected to the inside of the tooth block 32, and the connecting groove 34 is opened on both sides of the outer wall of the collection box 33.

[0054] The collection structure also includes a rotating gear 35, a threaded rod 36, a bolt 37, a connecting plate 38, and a cooler 39;

[0055] Rotating gear 35 is rotatably connected to the inside of collection box 33, threaded rod 36 is fixedly connected to the top of rotating gear 35, bolt 37 is threadedly connected to the top of threaded rod 36, connecting plate 38 is fixedly connected to the top of bolt 37, and cooler 39 is fixedly connected to the rear of collection box 33.

[0056] The collection box 33 is used to open the connecting groove 34. The toothed block 32 passes through the connecting groove 34 and enters the interior of the collection box 33. The cooler 39 is used to cool the ethylene propylene copolymer particles. The rotating gear 35 and the toothed block 32 are meshed.

[0057] With the auxiliary cooperation between the slide rail 31 and the toothed block 32, when the collection box 33 is pulled outward, the connecting plate 38 can be vertically raised inside the collection box 33.

[0058] Working principle: When workers collect ethylene-propylene copolymer particles;

[0059] First, pull out the collection box 33 inside the slide rail 31. Since the toothed block 32 passes through the inside of the collection box 33 through the connecting groove 34, the rotating gear 35 and the toothed block 32 can mesh and connect at the same time as the collection box 33 is pulled out.

[0060] Next, the rotating gear 35 can be rotated, which will drive the threaded rod 36 to rotate. At the same time, the bolt 37 can slide vertically upward along the threaded trajectory outside the threaded rod 36, so that the connecting plate 38, which is fixedly connected to the bottom with two sets of bolts 37, can slide upward. The connecting plate 38 can lift the ethylene propylene copolymer particles collected inside the collection box 33.

[0061] This step helps staff to quickly and easily handle ethylene-propylene copolymer granules, avoiding repeated bending and stooping movements and reducing the physical burden on staff.
