Abstract
Description
Technical Field
[0001] The invention relates to the technical field of heat shrink tube processing, and more specifically to an extrusion device for heat shrink tube processing. Background Art
[0002] Heat shrink tubing is a special polyolefin material tube with high temperature shrinkage, soft flame retardant, insulation and corrosion resistance. When preparing the heat shrink tubing, the raw materials are first mixed and granulated into a masterbatch according to the formula, and then the masterbatch is added to the hopper of the extruder. After heating and melting by the extruder, it is extruded and molded, cooled in a water tank, blown dry and rolled, and then irradiated and shaped, and expanded into a finished product to complete the preparation of the heat shrink tubing.
[0003] When the heat shrink tube is extruded, the masterbatch needs to be added to the drying hopper. Since the masterbatch contains a certain amount of moisture, if the moisture content is not well controlled, water vapor will be formed during the extrusion process, causing the extruded tube to foam. Therefore, the masterbatch is dried in the drying hopper before entering the extruder. However, the current drying hopper has limited drying effect when drying a large amount of masterbatch, and impurities such as dust are easily dropped into the masterbatch during transportation, which also affects the product quality.

[0025] In the embodiment of the present application, the positions of the heating plate 2 and the support plate 4 are fixed to support the present application, and the heating plate 2 and the support plate 4 can be fixed on a bracket at the processing site. This is a conventional technical means in the field and the present application does not define it in detail. The support column 7 connects the heating plate 2 and the mixing mechanism 6, so that the support column 7 can support the heating plate 2 to ensure the stability of the heating plate 2. The interior of the heating plate 2 is provided with an installation hole and a connecting hole, and the connecting hole can be used for discharging. The installation hole and the loading plate 101 can receive the raw materials transported from the masterbatch loading machine 1.
[0026] Reference Figure 3 , Figure 4 as well as Figure 5 The drying and stirring mechanism 3 includes a rotating motor 301 that can provide power. The bottom end of the rotating motor 301 is fixedly connected to an output shaft 302. The bottom end of the output shaft 302 is fixedly connected to a feeding circular plate 303. The bottom end of the feeding circular plate 303 contacts the top end of the heating plate 2. The inside of the feeding circular plate 303 is provided with three storage grooves distributed at equal angles. The heating plate 2 seals the storage grooves of the feeding circular plate 303. The top of each storage groove in the feeding circular plate 303 is fixedly connected to a mesh plate 309. The bottom end of the side of the output shaft 302 is fixedly connected to a three-way plate 305. The side of the three-way plate 305 is provided with three angles distributed at equal angles, and the three angles of the three-way plate 305 are movable. It is movably connected with a rotating shaft 306, the top of which is fixedly connected with a connecting gear 308, the bottom of which is fixedly connected with a stirring blade 307, the rotating shaft 306 and the stirring blade 307 are both located in the storage groove of the feeding circular plate 303, the bottom end of the support plate 4 is fixedly connected with a fixed gear 310, a avoidance hole is provided in the fixed gear 310 for the output shaft 302 to rotate, and the output shaft 302 does not contact the fixed gear 310 when rotating, the side of the connecting gear 308 is meshed with the side of the fixed gear 310, the top of the rotating shaft 306 is movably connected with a limiting ring 311, and the bottom end of the support plate 4 is provided with a limiting groove matched with the limiting ring 311.
[0027] In the embodiment of the present application, when the rotating motor 301 drives the output shaft 302 to output, the output shaft 302 will drive the loading circular plate 303 and the three-way plate 305 to rotate synchronously. When the loading circular plate 303 rotates, the storage tank in the loading circular plate 303 passes through the masterbatch feeder 1 and the cleaning mechanism 5 in sequence. The loading work will be performed when passing through the masterbatch feeder 1, and the discharging work will be performed when passing through the cleaning mechanism 5. The heating plate 2 seals the loading circular plate 303 to prevent leakage of raw materials. When the raw materials pass through the heating plate 2, the heating plate 2 will dry the raw materials. During drying, the water vapor will move upward, so the water vapor can be discharged through the mesh plate 309, and the mesh plate 309 can prevent the raw materials from being thrown out when the loading circular plate 303 rotates. When the output shaft 302 drives the feeding circular plate 303 and the three-way plate 305 to rotate, the three-way plate 305 drives the connecting gear 308 to revolve around the fixed gear 310 through the rotating shaft 306. Since the position of the fixed gear 310 is fixed by the support plate 4, the fixed gear 310 cannot rotate, and the connecting gear 308 is meshed with the fixed gear 310, so the connecting gear 308 will drive the rotating shaft 306 and the stirring blade 307 to rotate. When the stirring blade 307 rotates, it stirs the raw materials in the storage tank to improve the drying effect. The upper part of the connecting gear 308 is connected to the limit ring 311, and the limit ring 311 can rotate under the support plate 4, thereby ensuring the stability of the connecting gear 308 during rotation.
[0028] Reference Figure 3 as well as Figure 6 The mixing mechanism 6 includes a mixing barrel 601 that can receive raw materials, the bottom end of the output shaft 302 is fixedly connected to the connecting shaft 304, the bottom end of the side of the connecting shaft 304 is fixedly connected to the mixing blade 603, the top of the mixing barrel 601 is fixedly connected to the sealing cover 602, the top of the sealing cover 602 is fixedly connected to the bottom end of the cleaning mechanism 5, the mixing blade 603 is located in the mixing barrel 601, and the mixing blade 603 is provided with four groups from top to bottom, the four groups of mixing blades 603 are equidistantly distributed inside the mixing barrel 601, and the inside of the feeding circular plate 303 is fixedly connected to the top of the connecting shaft 304.
[0029] In the embodiment of the present application, when the raw materials enter the hot melt extruder 8 for hot melt extrusion, the mixing blades 603 will mix the raw materials again to make the proportioned raw materials more uniform, thereby improving the quality of the heat shrink tube after extrusion. The sealing cover 602 can support the cleaning mechanism 5 and the support column 7, and the four groups of mixing blades 603 can make the raw materials mix better. The raw materials entering the mixing barrel 601 are dried and dust and impurities are removed to ensure the quality of the heat shrink tube finally produced.
[0030] Reference Figure 2 , Figure 7 as well as Figure 8 The cleaning mechanism 5 includes a filter cartridge 501 that can receive the dried raw materials, the side of the filter cartridge 501 is fixedly connected to a collection box 503, and a filter hole is provided on the side of the filter cartridge 501 close to the collection box 503, and the side of the filter cartridge 501 away from the collection box 503 is fixedly connected to the exhaust pipe 9, and the gas in the exhaust pipe 9 will enter the filter cartridge 501, and the interior of the collection box 503 is movably connected to a threaded rod 504, and the bottom end of the threaded rod 504 is fixedly connected to a servo motor 505, and the bottom end of the servo motor 505 is fixedly connected to the top end of the sealing cover 602 in the mixing mechanism 6, and the bottom end of the filter cartridge 501 is fixedly connected to a connecting cylinder 502, and the bottom end of the connecting cylinder 502 is fixedly connected to the inside of the sealing cover 602, and the raw materials in the filter cartridge 501 will pass through the connecting cylinder 502 and the sealing cover 602 into the mixing cylinder 601.
[0031] In the embodiment of the present application, the exhaust pipe 9 will pass gas into the filter cartridge 501. At this time, the raw material is blown to the filter holes of the filter cartridge 501. Under the continuous blowing of the gas, dust and impurities will pass through the filter holes into the collection box 503, and the clean raw material masterbatch will continue to fall and enter the filter cartridge 501 through the connecting tube 502. The servo motor 505 drives the threaded rod 504 to rotate. When the threaded rod 504 rotates, the brush plate 506 moves upward or downward, thereby cleaning the filter holes on the side of the filter cartridge 501 to avoid clogging of the filter holes. In addition, dry hot air can be passed into the gas in the exhaust pipe 9, which can have the effect of drying again. The side of the collection box 503 away from the filter cartridge 501 is connected with a gas exhaust pipe, thereby discharging the gas passed into the exhaust pipe 9 and the impurities in the raw material. Providing a gas exhaust pipe to discharge the gas is a conventional technical means in this field, and the present application does not make detailed limitations on its structure.
[0032] The working principle of the present invention is as follows: the masterbatch feeder 1 feeds the raw material masterbatch into the storage tank of the feeding circular plate 303. When a storage tank in the drying and stirring mechanism 3 moves to the top of the masterbatch feeder 1, the raw material will enter the storage tank. When the storage tank moves away, the next storage tank will move to the top of the masterbatch feeder 1 again, and the rotating motor 301 drives the feeding circular plate 303 to rotate through the output shaft 302 to perform the feeding work; When the storage tank is moved away from the top of the masterbatch feeder 1, the storage tank will move above the heating plate 2, and the heating plate 2 will dry the raw materials, and the water vapor during drying will be discharged through the mesh plate 309. When the storage tank is moved to the top of the cleaning mechanism 5, the heating plate 2 is provided with a connecting hole. At this time, the storage tank is connected to the filter cartridge 501 in the cleaning mechanism 5, and the raw materials will fall into the filter cartridge 501. The storage tank will be emptied, and the emptied storage tank will move to the top of the masterbatch feeder 1 again for continuous feeding. When the output shaft 30 When the output shaft 302 rotates, the three-way plate 305 is driven to rotate. When the three-way plate 305 rotates, the rotating shaft 306 and the connecting gear 308 above it are driven to revolve around the fixed gear 310. The position of the fixed gear 310 is fixed by the support plate 4. The connecting gear 308 is meshed with the fixed gear 310. Therefore, the connecting gear 308 drives the rotating shaft 306 to rotate in the storage tank. The rotating shaft 306 drives the stirring blade 307 to rotate in the storage tank. At this time, the raw materials in the storage tank are stirred to improve the drying efficiency. When the raw material falls into the filter cartridge 501, the exhaust pipe 9 will introduce gas into the filter cartridge 501, and the raw material will be blown to the filter hole of the filter cartridge 501. Under the continuous blowing of the gas, dust and impurities will pass through the filter hole and enter the collection box 503. Clean raw material masterbatch will continue to fall and enter the filter cartridge 501 through the connecting cylinder 502. The servo motor 505 drives the threaded rod 504 to rotate. When the threaded rod 504 rotates, the brush plate 506 moves upward or downward, thereby cleaning the filter hole on the side of the filter cartridge 501 to avoid clogging of the filter hole. When the clean raw materials enter the mixing barrel 601, the rotation of the output shaft 302 will synchronously drive the connecting shaft 304 to rotate. When the connecting shaft 304 rotates, it drives the mixing blades 603 to rotate in the mixing barrel 601. The mixing blades 603 will mix the raw materials entering the mixing barrel 601 again to ensure that the different raw materials are mixed evenly before entering the hot melt extruder 8, and the extrusion work is completed through the hot melt extruder 8.
[0033] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
