Technical Field

[0001] This invention relates to the field of plastic materials, and more specifically to a process for preparing plastic granules. Background Technology

[0002] Plastic granules are small granular materials formed after plastic raw materials are melted, processed, and granulated. These granules are commonly used as raw materials for plastic products, and are processed into various plastic products such as plastic bags, bottles, containers, and pipes through processes such as heating and molding. There are many types of plastic granules, including polyethylene, polypropylene, polyvinyl chloride, and polystyrene granules, each with its own specific physical and chemical properties, which can be used to manufacture plastic products with different performance characteristics and applications. Currently, the plastic granule manufacturing process cannot change the diameter of the produced plastic granules. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a plastic granule preparation process, the beneficial effect of which is that it facilitates the switching of molding holes to manufacture plastic granules of different diameters.

[0004] A process for preparing plastic granules includes the following steps:

[0005] S1: Rotate the wheel of the preparation system to select forming holes of different diameters and change the position of the sealing plate in the forming tube;

[0006] S2: The plastic raw material is added from the injection funnel of the preparation system to the injection tube and the molding tube, and the molding box cools the plastic raw material;

[0007] S3: Start the rotary motor to drive the cutter to cut the solidified plastic into plastic granules, while driving the base plate to move repeatedly to screen the plastic granules;

[0008] S4: Start the hydraulic cylinder to push the slide plate upward, which in turn moves the push plate forward and pushes the plastic particles out from the rotating plate.

[0009] The preparation system includes a molding box, two molding tubes, two rotating wheels, and two round shafts. The two molding tubes are fixedly connected inside the molding box, the two round shafts are rotatably connected to both sides of the molding box, and the two rotating wheels are fixedly connected to the corresponding round shafts.

[0026] A process for preparing plastic granules includes the following steps:

[0027] S1: Rotate the wheel 201 of the preparation system, select molding holes 202 of different diameters and change the position of the sealing plate 109 in the molding tube 102;

[0028] S2: The plastic raw material is added from the injection funnel of the preparation system to the injection tube 108 and the molding tube 102, and the molding box 101 cools the plastic raw material.

[0029] S3: Start the rotary motor to drive the cutter 208 to cut the solidified plastic into plastic granules, while driving the base plate 401 to move repeatedly to screen the plastic granules;

[0030] S4: Start the hydraulic cylinder to push the slide plate 402 upward, which drives the push plate 409 to move forward and push the plastic particles out from the rotating plate 405.

[0031] like Figure 4-7 As shown, this example allows for easy switching of the forming hole 202 to manufacture plastic granules of different diameters.

[0032] The preparation system includes a molding box 101, two molding tubes 102, two rotating wheels 201, and two round shafts 203. The two molding tubes 102 are fixedly connected inside the molding box 101, and the two round shafts 203 are rotatably connected to both sides of the molding box 101. The two rotating wheels 201 are fixedly connected to the corresponding round shafts 203. Each rotating wheel 201 is provided with five molding holes 202 with different outlet diameters. The inlet position of the molding holes 202 is aligned with the molding tubes 102, so that the rotating wheels 201 can be rotated to align the molding holes 202 of different diameters with the molding tubes 102. Thus, when the plastic raw liquid flows from the molding tubes 102 into the molding holes 202, it can flow out from the outlets of different diameters, thereby producing plastic granules of different diameters. This achieves the effect of easily switching the molding holes 202 to produce plastic granules of different diameters.

[0033] like Figure 4-5 As shown, this example allows for easy repositioning of the sealing plate 109 within the forming tube 102.

[0034] The preparation system also includes a threaded rod I 104, a top plate 107, an injection tube 108, and two sealing plates 109. The threaded rod I 104 is rotatably connected to the top of the molding box 101, the top plate 107 is threadedly connected to the threaded rod I 104, the injection tube 108 is fixedly connected to the top plate 107, and an injection funnel is provided at the top of the injection tube 108. The two sealing plates 109 are respectively fixedly connected to the bottom of the injection tube 108 and are respectively slidably connected to the corresponding molding tubes 102. Plastic raw material can be added to the injection tube 108 through the injection funnel. When the threaded rod I 104 rotates, it can drive the top plate 107 to slide forward, thereby driving the injection tube 108 to push the two sealing plates 109 forward, thus achieving the effect of easily changing the position of the sealing plates 109 in the molding tube 102.

[0035] like Figure 4-7 As shown, this example can achieve the effect of making the sealing plate 109 slide when the wheel 201 rotates.

[0036] The preparation system also includes a bevel gear set I 103, a threaded rod II 105, and a rack I 106. One end of the bevel gear set I 103 is fixedly connected to the threaded rod I 104, and the other end is rotatably connected to the molding box 101. The rack I 106 is threadedly connected to the threaded rod II 105. The outer side of the rotating wheel 201 is provided with teeth. The rack I 106 is meshed with two rotating wheels 201 respectively for transmission. The molding box 101 is provided with coolant. Therefore, when the rotating wheel 201 rotates, it can drive the rack I 106 to move upward. The rack I 106 drives the threaded rod II 105 and the bevel gear set I 103 to rotate, which in turn drives the threaded rod I 104 to rotate, causing the sealing plate 109 to move. This changes the position of the sealing plate 109 in the molding tube 102, so that when manufacturing plastic granules of different diameters, the plastic raw material is cooled in the molding box 101 for different times. When the plastic granules are larger in diameter, the plastic raw material is cooled in the molding box 101 for a longer time, and vice versa. This achieves the effect of making the sealing plate 109 slide when the rotating wheel 201 rotates.

[0037] like Figure 4-7 As shown, this example demonstrates how driving the cutter 208 can cut solidified plastic into plastic granules.

[0038] The preparation system also includes two wheel frames 204, a fixed rod 205, a support 206, a rotating shaft 207, and a cutter 208. The fixed rod 205 is fixedly connected to the bottom of the molding box 101. The two wheel frames 204 are fixedly connected to the fixed rod 205 and rotatably connected to the outside of the two rotating wheels 201. The support 206 is fixedly connected between the two wheel frames 204. The rotating shaft 207 is rotatably connected to the support 206. The cutter 208 is fixedly connected to the rotating shaft 207. The output shaft of a rotary motor is fixedly connected to the rotating shaft 207. Thus, the two wheel frames 204 make the cutter 208 stably contact the two rotating wheels 201. Thus, the rotary motor can drive the rotating shaft 207 to rotate. Thus, the rotating shaft 207 drives the cutter 208 to rotate. Thus, the cutter 208 cuts the plastic column made from the molding hole 202 into plastic granules, thereby achieving the effect of driving the cutter 208 to cut solidified plastic into plastic granules.

[0039] like Figure 4-9 As shown, this example can achieve the effect of sieving plastic particles by moving the base plate 401.

[0040] The preparation system also includes a water tank 301, a push rod 302, and a base plate 401. The water tank 301 is fixedly connected to the bottom of the molding box 101. The push rod 302 is slidably connected to the water tank 301. Two grooves 307 are provided in the water tank 301. The base plate 401 is fixedly connected to the push rod 302. Two sliding rods are fixedly connected to the base plate 401. The two sliding rods are slidably connected to the two grooves 307 respectively. The base plate 401 is provided with sieve holes. The cut plastic particles fall into the base plate 401 and are immersed in the water tank for cooling. When the push rod 302 slides along the water tank 301, it can drive the base plate 401 to slide in the water tank 301. As a result, unqualified plastic particles will be screened out from the sieve holes of the base plate 401, thus achieving the effect of driving the base plate 401 to move and screen the plastic particles.

[0041] like Figure 4-9 As shown, this example allows for the simultaneous cutting and screening of plastic granules.

[0042] The fabrication system also includes a connecting rod 303, an eccentric wheel 304, and a bevel gear set II 305. One end of the bevel gear set II 305 is rotatably connected to the water tank 301, and a round shaft is fixedly connected to one end of the bevel gear set II 305. The round shaft and the rotating shaft 207 are connected by a rotating belt 306. The other end of the bevel gear set II 305 is rotatably connected to the water tank 301, and an eccentric wheel 304 is fixedly connected to the other end of the bevel gear set II 305. One end of the connecting rod 303 is rotatably connected to the push rod 302, and the other end of the connecting rod 303 is rotated... The eccentric wheel 304 is connected to the eccentric position. When the rotating shaft 207 drives the cutter 208 to cut plastic granules, the rotating belt 306 simultaneously drives one end of the bevel gear set II 305 to rotate, and the other end of the bevel gear set II 305 rotates together, causing the eccentric wheel 304 to rotate. The eccentric wheel 304 then drives the connecting rod 303 and the push rod 302 to reciprocate. The push rod 302 then drives the base plate 401 to move repeatedly, thus achieving the effect of cutting and screening plastic granules simultaneously.

[0043] like Figure 7-11 As shown, this example allows for easy removal of plastic granules from the water tank 301.

[0044] Since the preparation system also includes a slide plate 402, which is slidably connected to the base plate 401, a hydraulic cylinder is provided between the slide plate 402 and the base plate 401, cooling water is provided in the water tank 301, and sieve holes are provided on the slide plate 402, when plastic particles fall into the base plate 401, they will be placed above the slide plate 402. Thus, both the base plate 401 and the slide plate 402 are immersed in the cooling water in the water tank 301. After screening is completed, the hydraulic cylinder is driven to move the slide plate 402 upward, and the slide plate 402 carries the plastic particles out of the water tank 301, thereby achieving the effect of facilitating the removal of plastic particles from the water tank 301.

[0045] like Figure 10-11 As shown, this example can facilitate the outward rotation of the rotating plate 405.

[0046] Since the preparation system also includes two slide grooves 403, a slide shaft 404 and a rotating plate 405, the two slide grooves 403 are fixedly connected to the base plate 401, the rotating plate 405 is rotatably connected to the slide plate 402, and the slide shaft 404 is fixedly connected to the rotating plate 405. The two ends of the slide shaft 404 are slidably connected to the corresponding slide grooves 403. When the slide plate 402 moves upward, it drives the rotating plate 405 to move upward together. Then the rotating plate 405 pushes the slide shaft 404 to slide outward, and the slide shaft 404 causes the rotating plate 405 to flip outward, thereby achieving the effect of facilitating the rotation of the rotating plate 405 outward.

[0047] like Figure 4-11As shown, this example can achieve the effect of pushing the pusher plate 409 to push the plastic particles out from the rotating plate 405.

[0048] The preparation system also includes a gear 406, a rack II 407, a threaded rod III 408, and a push plate 409. The rack II 407 is fixedly connected to the base plate 401, the push plate 409 is slidably connected above the slide plate 402, the threaded rod III 408 is threadedly connected inside the push plate 409, and the gear 406 is fixedly connected to the threaded rod III 408. The gear 406 and the rack II 407 are meshed and connected for transmission. When the slide plate 402 moves upward, it drives the push plate 409 to move upward as well. The push plate 409 then drives the gear 406 and the threaded rod III 408 to move upward as well. The rack II 407 drives the gear 406 and the threaded rod III 408 to rotate as well. The threaded rod III 408 then drives the push plate 409 to move forward. The push plate 409 then pushes the plastic particles above the slide plate 402 out from the rotating plate 405, thus achieving the effect of pushing the plastic particles out from the rotating plate 405.
