Description

Technical Field

[0001] This utility model relates to the field of processing and production equipment, and in particular to a feeding device for a double-roller plasticizer. Background Technology

[0002] With the improvement of automation level in manufacturing, the plastics processing industry is also developing towards automation and intelligence. In the plastics processing process, various raw materials such as plastic granules, powders, and additives need to be added to a two-roller plasticizer for plasticizing or mixing. A continuous, efficient, and stable feeding device can ensure a continuous supply of materials and make the plasticizing process run smoothly.

[0003] Most existing technologies use screw conveyor feeding devices, which mainly consist of a motor, reducer, screw shaft, conveying pipe and feed hopper. The motor drives the screw shaft to rotate through the reducer. The screw shaft is equipped with screw blades. After the material enters the conveying pipe from the feed hopper, when the screw blades rotate, the blade surface contacts the material and generates friction. This friction overcomes the resistance between the material and the inner wall of the conveying pipe, allowing the material to move forward gradually along the conveying pipe and finally be pushed into the barrel of the plasticizer, thus achieving stable material conveying.

[0004] Regarding the aforementioned technologies, in actual operation, the screw conveyor feeding device has a fixed outlet position. After the material is pushed to a fixed position by the screw conveyor, it can only be placed into the designated feeding area of ​​the plasticizer. Different plasticizers may require different feeding positions, and the fixed feeding position cannot meet the needs of such dynamic changes, resulting in poor flexibility. Utility Model Content

[0005] To improve the flexibility of the feeding device, this application provides a feeding device for a twin-roll plasticizer.

[0006] This application provides a feeding device for a twin-roll plasticizer, which adopts the following technical solution: A feeding device for a double-roller plasticizer includes a base, a plasticizer body fixed to the upper end of the base, and material collection boxes on both sides of the plasticizer body. Each material collection box has a feed inlet at its upper end and a stirring assembly inside. The stirring assembly is used to stir the material in the material collection box. A pump is located on one side of the material collection box to extract material from the box. A connecting pipe is connected to one side of the pump, and a discharge head is connected to the side of the connecting pipe away from the pump. A bracket is fixed to the upper end of the base, and two cylinders are located on the upper end of the bracket. A connecting frame is fixed to the output end of each cylinder, and the connecting frame is slidably connected to the bracket along its width. A connecting block is located on one side of the connecting frame, and a moving component is located inside the connecting frame to drive the connecting block to move laterally. A clamping block is located inside the connecting block and is rotatably connected to the connecting block. A positioning groove is opened on the surface of the clamping block, and the discharge head is located in the positioning groove and engaged with the clamping block. A rotating block is fixed to one end of the clamping block, and a limiting element is provided on the rotating block for positioning.

[0007] By adopting the above technical solution, the base supports the plasticizer body and the collection box. The material enters the collection box through the feed inlet. The stirring component is activated to stir the material, reducing the probability of material agglomeration. The pump draws the material out of the collection box and flows to the connecting pipe, and then out from the discharge head. The bracket supports the connecting block. The cylinder is activated to drive the connecting frame to slide along the width of the bracket. The sliding of the connecting frame drives the connecting block to move. The movement of the connecting block drives the clamping block to move. The movement of the clamping block drives the discharge head to move, which facilitates the adjustment of the discharge position of the discharge head. The moving component drives the moving block to move laterally. The movement of the moving block drives the clamping block to move laterally. The movement of the clamping block drives the discharge head to move laterally, so that the discharge head feeds the plasticizer evenly. The rotating block rotates, which drives the clamping block to rotate. The rotation of the clamping block drives the discharge head to rotate, thereby adjusting the angle of the discharge head and thus adjusting the feeding position of the plasticizer, improving the flexibility of the feeding device.

[0008] Optionally, the moving component includes a motor, a lead screw, and a positioning rod. The motor is fixed to one side of the connecting frame, the lead screw is located inside the connecting frame and is rotatably connected to the connecting frame, and the output shaft of the motor is fixed coaxially with the lead screw. The connecting block is threadedly connected to the lead screw, the positioning rod passes through the connecting block and is fixedly connected to the connecting frame, and the connecting block is slidably connected to the positioning rod along the length of the positioning rod.

[0009] By adopting the above technical solution, when the motor starts, it drives the lead screw to rotate. The positioning rod limits the connecting block. The rotation of the lead screw drives the connecting block to move laterally. The lateral movement of the connecting block drives the clamping block to move laterally. The lateral movement of the clamping block drives the discharge head to move laterally, so that the discharge head moves along the length of the plasticizer to gradually feed the material, thereby improving the uniformity of the feeding device.

[0010] Optionally, the mixing assembly includes a second motor, a rotating rod, and two mixing rods. The second motor is fixed at the upper end of the collection box, the rotating rod is located inside the collection box, and the output shaft of the second motor is coaxially fixed with the rotating rod. The two mixing rods are fixed at both ends of the rotating rod. The mixing rods are arranged vertically, and a number of mixing blades are fixed on the surface of the mixing rods. The number of mixing blades are evenly distributed along the length of the mixing rods.

[0011] By adopting the above technical solution, the second motor starts and drives the rotating rod to rotate, which in turn drives the stirring rod to rotate, which in turn drives the stirring blades to rotate. This allows the stirring blades to fully stir the material in the collection box, reducing the probability of material clumping and sedimentation, ensuring uniform mixing of the material, and facilitating subsequent feeding.

[0012] Optionally, the plasticizing machine body includes a housing, two rotating rollers, two gears, and a motor. The housing is fixed to the upper end of the base. The two rotating rollers are located inside the housing and are rotatably connected to the housing. The gears correspond one-to-one with the rotating rollers. The gears are fixed to one end of the rotating rollers and mesh with each other. The motor is fixed to one side of the housing. The output shaft of the motor is fixed to the shaft of any gear cylinder. A collection box is provided below the two rotating rollers. The collection box is slidably connected to the housing along the width direction of the housing.

[0013] By adopting the above technical solution, the motor starts three times to drive the connected gears to rotate, thereby driving the two gears to rotate simultaneously. The rotation of the two gears drives the two rotating rollers to rotate in opposite directions, realizing the plasticizing process of the material. The collection box collects the processed material. The collection box can slide along the width of the box to facilitate the collection of material falling from the rotating rollers, which is convenient for subsequent cleaning and recycling.

[0014] Optionally, the collection box is equipped with two scrapers, which are located directly below the two rotating rollers. The scrapers are used to scrape the material on the surface of the rotating rollers.

[0015] By adopting the above technical solution, while the rotating roller is rotating, the scraper scrapes the material on the rotating roller, reducing the material residue on the surface of the rotating roller and improving the stability of the plasticizing machine body.

[0016] Optionally, two sliding rods are provided on both sides of the clamping block. The two sliding rods are located at both ends of the clamping block respectively. The sliding rods are slidably connected to the clamping block in the lateral direction. A groove is opened on the surface of the discharge head. The sliding rod is inserted into the groove and is engaged with the inner wall of the groove. A fixing nut is provided at one end of the sliding rod. The fixing nut is threadedly connected to the sliding rod.

[0017] By adopting the above technical solution, after the discharge head enters the positioning groove, it slides the slide rod horizontally, so that the slide rod is inserted into the groove and engaged with the inner wall of the groove. By rotating the fixing nut, the fixing nut and the clamping block cooperate to limit the slide rod, thereby improving the connection stability between the discharge head and the clamping block, reducing the separation of the discharge head from the clamping block during use, and ensuring stable material conveying.

[0018] Optionally, the limiting component includes several limiting rods, elastic elements, and a locking block. Several limiting rods are fixed on the side of the rotating block near the connecting block, and the limiting rods are evenly distributed along the circumference of the rotating block. The locking block is fixed on the side of the connecting block near the rotating block, and the locking block is slidably connected to the connecting block in the transverse direction. A locking groove is opened on the surface of the locking block, and any limiting rod is inserted into the locking groove.

[0019] By adopting the above technical solution, when it is necessary to adjust the angle of the discharge head, push the locking block. At this time, the elastic element is compressed, causing the locking block to separate from the limit rod. Rotate the rotating block, which drives the clamping block to rotate, and the clamping block drives the discharge head to rotate. After the adjustment is completed, release the locking block. Under the action of the elastic element, the locking block engages with the corresponding limit rod, reducing the probability of accidental rotation and improving the stability of the device.

[0020] Optionally, a filter screen is provided at the feed inlet, and the filter screen is detachably connected to the collection box.

[0021] By adopting the above technical solution, the filter screen filters impurities in the material entering the collection box, reducing the impact of impurities on the plasticizing quality. The detachable connection makes it easy to clean or replace the filter screen, improving the convenience of using the filter screen.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Rotate the rotating block, which in turn drives the clamping block to rotate, which in turn drives the discharge head to rotate. Adjust the angle of the discharge head to adjust the feeding position of the plasticizer and improve the flexibility of the feeding device. 2. The second motor starts and drives the rotating rod to rotate, which in turn drives the stirring rod to rotate, which in turn drives the stirring blades to rotate. This allows the stirring blades to fully mix the material in the collection box, reducing the probability of material clumping and sedimentation, ensuring uniform mixing of the material, and facilitating subsequent feeding. 3. When it is necessary to adjust the discharge head angle, push the locking block. At this time, the elastic element is compressed, causing the locking block to separate from the limit rod. Rotate the rotating block, which drives the clamping block to rotate, and the clamping block drives the discharge head to rotate. After the adjustment is completed, release the locking block. Under the action of the elastic element, the locking block engages with the corresponding limit rod, reducing the probability of accidental rotation and improving the stability of the device.

[0033] Reference Figure 1 and Figure 2A feeding device for a double-roller plasticizer includes a base 1, with a plasticizer body 11 fixedly mounted on the upper end of the base 1. The base 1 supports the plasticizer body 11. The plasticizer body 11 includes a housing 111, two rotating rollers 1112, two gears 1113, and a motor 1114. The housing 111 is fixedly mounted on the upper end of the base 1. The two rotating rollers 1112 are located inside the housing 111 and are rotatably connected to the housing 111.

The motor 1114 is fixed on one side of the housing 111, and the output shaft of the motor 1114 is fixed to the shaft of any of the gears 1113.

[0034] Reference Figure 2 and Figure 3 When the motor 1114 starts, it drives the connected gear 1113 to rotate, thereby driving the two gears 1113 to rotate simultaneously. The rotation of the two gears 1113 drives the two rotating rollers 1112 to rotate in opposite directions, realizing the plasticizing process of the material. A collection box 1115 is provided below the two rotating rollers 1112. The collection box 1115 is slidably connected to the box 111 along the width direction of the box body 111, which facilitates the collection of the material processed from the rotating rollers 1112, making it convenient for subsequent cleaning and recycling.

[0035] Reference Figure 4 Two collection boxes 12 are fixedly installed on the upper end of the base 1. The two collection boxes 12 are located on both sides of the plasticizing machine body 11. The upper end of the collection box 12 is provided with a feed inlet 121. The material enters the collection box 12 through the feed inlet 121. A filter screen 126 is provided at the feed inlet 121. The filter screen 126 filters impurities in the material entering the collection box 12, reducing the impact of impurities on the plasticizing quality. The filter screen 126 is detachably connected to the collection box 12, which facilitates the cleaning or replacement of the filter screen 126 and improves the convenience of using the filter screen 126.

[0036] Reference Figure 4 A second motor 1221 is fixedly installed at the upper end of the collection box 12. A rotating rod 1222 is fixedly installed on the output shaft of the second motor 1221. When the second motor 1221 starts, it drives the rotating rod 1222 to rotate. A stirring rod 1223 is fixedly installed at both ends of the rotating rod 1222. The rotation of the rotating rod 1222 drives the stirring rod 1223 to rotate. Several stirring blades 1224 are fixedly installed on the surface of the stirring rod 1223. The stirring blades 1224 are evenly distributed along the length of the stirring rod 1223. The rotation of the stirring rod 1223 drives the stirring blades 1224 to rotate, so that the stirring blades 1224 can fully stir the material in the collection box 12, reduce the probability of material clumping, and make the material evenly mixed, which is beneficial to the subsequent feeding work.

[0037] Reference Figure 1 and Figure 5A material pump 125 is provided on one side of the collection box 12. A connecting pipe 1251 is connected to one side of the material pump 125. The material pump 125 draws material from the collection box 12 and flows to the connecting pipe 1251. The connecting pipe 1251 is a flexible hose. The end of the connecting pipe 1251 away from the material pump 125 is connected to a discharge head 1252. The material flowing to the connecting pipe 1251 then flows out from the discharge head 1252. The two discharge heads 1252 correspond to the two rotating rollers 1112 and respectively convey material to the two rotating rollers 1112. A bracket 13 is fixedly provided at the upper end of the base 1. Two cylinders 124 are fixedly provided at the upper end of the bracket 13. A connecting frame 1241 is fixedly installed at the output end of cylinder 124. A motor 1231 is fixedly installed on one side of the connecting frame 1241. A lead screw 1232 is installed inside the connecting frame 1241. The lead screw 1232 is coaxially fixed with the output shaft of the motor 1231. When the motor 1231 starts, it drives the lead screw 1232 to rotate. A connecting block 1242 is installed at one end of the lead screw 1232. The connecting block 1242 is threadedly connected to the lead screw 1232. A positioning rod 1233 is fixedly installed inside the connecting frame 1241. The positioning rod 1233 passes through the connecting block 1242, and the connecting block 1242 is slidably connected to the positioning rod 1233 along the length direction of the positioning rod 1233.

[0038] Reference Figure 5 The positioning rod 1233 limits the connection block 1242. The screw 1232 rotates and drives the connection block 1242 to move laterally. The connection block 1242 is provided with a clamping block 1243. The clamping block 1243 is rotatably connected to the connection block 1242. The connection block 1242 moves laterally and drives the clamping block 1243 to move laterally. The surface of the clamping block 1243 is provided with a positioning groove 1244. The discharge head 1252 is located in the positioning groove 1244. The clamping block 1243 moves laterally and drives the discharge head 1252 to move laterally, so that the discharge head 1252 feeds material evenly along the length of the rotating roller 1112, thereby improving the uniformity of feeding by the feeding device.

[0039] Reference Figure 2 When the cylinder 124 is started, it drives the connecting frame 1241 to slide along the width of the bracket 13. The sliding of the connecting frame 1241 drives the connecting block 1242 to move. The movement of the connecting block 1242 drives the clamping block 1243 to move. The movement of the clamping block 1243 drives the discharge head 1252 to move, which facilitates the adjustment of the discharge position of the discharge head 1252 and improves the flexibility of the device.

[0040] Reference Figure 6 and Figure 7Two sliding rods 1245 are provided on both sides of the clamping block 1243. The two sliding rods 1245 are located at both ends of the clamping block 1243 respectively. The sliding rods 1245 are slidably connected to the clamping block 1243 in the transverse direction. The surface of the discharge head 1252 is provided with a groove 1246. After the discharge head 1252 enters the positioning groove 1244, the sliding rod 1245 slides in the transverse direction, so that the sliding rod 1245 is inserted into the groove 1246 and engaged with the inner wall of the groove 1246. One end of the sliding rod 1245 is provided with a fixing nut 1247. The fixing nut 1247 is threadedly connected to the sliding rod 1245. Then, the fixing nut 1247 is rotated. The fixing nut 1247 cooperates with the clamping block 1243 to limit the sliding rod 1245, thereby improving the connection stability between the discharge head 1252 and the clamping block 1243, reducing the separation of the discharge head 1252 from the clamping block 1243 during use, and ensuring stable material conveying.

[0041] Reference Figure 6 and Figure 7 A rotating block 1248 is fixedly provided at one end of the clamping block 1243. Several limiting rods 127 are fixedly provided on the side of the rotating block 1248 near the connecting block 1242. The limiting rods 127 are evenly distributed around the circumference of the rotating block 1248. A locking block 1272 is provided on the side of the connecting block 1242 near the rotating block 1248. The locking block 1272 is slidably connected to the connecting block 1242 in the transverse direction. A locking groove is opened on the surface of the locking block 1272. When it is necessary to adjust the angle of the discharge head 1252, the locking block 1272 is pushed. At this time, the elastic element 1271 is compressed, so that the locking block 1272 is separated from the limiting rods 127. The rotating block 1248 is rotated, which drives the clamping block 1243 to rotate. The rotation of the clamping block 1243 drives the discharge head 1252 to rotate, thereby adjusting the angle of the discharge head 1252, thereby adjusting the feeding position of the plasticizer and improving the flexibility of the feeding device. After adjustment, release the locking block 1272. Under the action of the elastic element 1271, the locking block 1272 engages with the corresponding limit rod 127, reducing the probability of accidental rotation and improving the stability of the device.

[0042] Reference Figure 2 The collection box 1115 is equipped with two scrapers 1116, which are located directly below the two rotating rollers 1112. While the rotating rollers 1112 are rotating, the scrapers 1116 scrape the material on the rotating rollers 1112 to reduce the material residue on the surface of the rotating rollers 1112 and improve the stability of the plasticizer body 11.

[0043] The implementation principle of the feeding device for a double-roller plasticizer in this application embodiment is as follows: the cylinder 124 starts and drives the connecting frame 1241 to move, the connecting block 1242 moves and drives the clamping block 1243 to move, the clamping block 1243 moves and drives the discharge head 1252 to move, thereby changing the position of the discharge head 1252 above the rotating roller 1112. When it is necessary to adjust the angle of the discharge head 1252, the locking block 1272 is pushed. At this time, the elastic element 1271 is compressed, causing the locking block 1272 to separate from the limiting rod 127. The rotating block 1248 is rotated, and the rotating block 1248 rotates and drives the clamping block 1243 to rotate. The rotation of the clamping block 1243 drives the discharge head 1252 to rotate, thereby adjusting the angle of the discharge head 1252, thereby adjusting the feeding position of the plasticizer, adapting to the feeding needs of more plasticizers, and improving the flexibility of the feeding device.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
