Description

Technical Field

[0001] This invention relates to the field of cable material mixing technology, specifically to an automatic cable material mixing machine. Background Technology

[0002] The cable material is mainly composed of polyvinyl chloride and other raw materials, which are mixed in a comprehensive ratio and put into the reactor for hot melting and stirring, and then coated on the outside of the cable.

[0003] Currently, the reactors used in cable material preparation are kept at high temperatures for extended periods, causing rust and corrosion on the inner walls. When polyvinyl chloride and other raw materials expand due to heat inside the reactor, the molten materials easily adhere to the inner wall of the reactor. When the molten materials need to be discharged, the material adhering to the inner wall of the reactor is difficult to remove. If the adhering material cannot be removed in time, it will damage the inner wall of the reactor.

[0004] The technical challenge that this invention aims to address is how to reduce interference with the mixing components during the hot-melting and stirring of cable materials in existing reactors, while preventing material adhesion to the inner wall of the reactor and maintaining a constant output of cable materials. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted in this invention is as follows: An automatic cable material mixing machine includes a melting mechanism, a stirring mechanism installed within the melting mechanism, and an electrothermal scraping mechanism installed within the melting mechanism. The melting mechanism includes a material holding assembly for holding cable material, a hydraulic component fixed to the material holding assembly by clamps, a protective cover located directly above the material holding assembly, a heat-spraying pipe fixedly installed on the protective cover, a linkage rack movably mounted on the material holding assembly, a transmission rocker arm movably mounted within the material holding assembly and driving the linkage rack, multiple sets of partitions located inside the material holding assembly, and a truss installed between the multiple sets of partitions. The material holding assembly includes a base, two pads mounted at both ends of the bottom of the base, a motor installed in a transverse hole inside the base, a track driven by an external shaft of the motor, a guide plate movably connected within the outer clamps of the base housing, and a movable... The base consists of a sealing pad movably installed inside the top housing of the base and a pin movably installed inside the base and penetrating into the sealing pad. The stirring mechanism includes a shaft movably installed inside the top housing of the base, three pressure-bearing outer rings installed outside the shaft, and multiple stirring rods evenly installed on the outer wall of the pressure-bearing outer rings. The electrothermal scraping mechanism includes two vertical frames installed at both ends of the truss, a horizontal bar bolted to the bottom of the vertical frame, a beam frame installed in the middle of the vertical frame, three heat-insulating ceramic buckles evenly installed on the beam frame, a positioning end rod movably installed inside the heat-insulating ceramic buckle, a plug inserted into the heat-insulating ceramic buckle and the positioning end rod, a heating coil connected inside the heat-insulating ceramic buckle and located outside the positioning end rod, wires connected to the three heating coils, and three springs evenly installed at three ends on the inner side of the horizontal bar.

[0007] In a preferred embodiment, the present invention can be further configured such that: trapezoidal slots are provided on both sides of the outer side of the base, and ventilation slots are provided on the inner wall of the trapezoidal slots; a rectangular groove is provided on the top of the guide plate, and the top of the guide plate is located directly below the hole in the base shell.

[0008] By adopting the above technical solution, the motor is fixedly installed in the horizontal hole on the outside of the base. The ventilation slots on the trapezoidal slots on both sides of the base are used to dissipate heat from the motor. When the fixed motor runs continuously and drives the track and shaft to rotate at high speed, it can be safely protected. At the same time, it can improve heat dissipation and ensure that the pressure-bearing outer ring on the shaft and the stirring rod can fully stir the cable material that is molten in the top shell of the base.

[0009] In a preferred embodiment, the present invention may be further configured such that: symmetrically distributed flow guide pipes are installed at both ends of the heat-spraying pipe fitting.

[0010] By adopting the above technical solution, the guide pipes at both ends of the heat-spraying pipe are inserted into the interior of the protective cover. When the external heat flow pipe transports the hot air along the heat-spraying pipe into the interior of the protective cover, the cable material stored in the top shell of the base will be continuously heated and softened in the encapsulated state.

[0011] In a preferred embodiment, the present invention can be further configured such that: the linkage rack is generally arc-shaped, a scraper is installed on the top of the linkage rack, and uniformly distributed tooth blocks are installed on the inner wall of the linkage rack; and two gear ends that mesh with the tooth blocks on the inner wall of the linkage rack are installed on the transmission rocker arm.

[0012] By adopting the above technical solution, the linkage rack is movably installed on the top shell of the base. When the control rocker arm is rotated, the gear end on the control rocker arm will drive the linkage rack to slide in a circle. The scraper installed on the linkage rack can effectively scrape off the material adhering to the inner wall of the top shell of the base.

[0013] In a preferred embodiment, the present invention may be further configured such that the heat-insulating ceramic buckle is made of ceramic material and the inner end of the heat-insulating ceramic buckle has a cylindrical hole.

[0014] By adopting the above technical solution, the heat-insulating ceramic buckle is installed on the beam frame, and the heating coil is fixed in conjunction with the heat-insulating ceramic buckle. At the same time, the scraper is fixed in conjunction with the positioning end rod. When the wire is energized, the heating coil can continuously release heat, and the heat energy radiated to the scraper can soften and scrape off the material adhering to the outside of the stirring rod.

[0015] In a preferred embodiment, the present invention may be further configured such that: a scraper is installed at the inner end of the positioning rod, and a trapezoidal pad is installed at the bottom of the scraper.

[0016] By adopting the above technical solution, after the cylindrical end of the positioning rod away from the heat insulation ceramic buckle is inserted into the inside of the scraper, the fixed scraper can stably scrape the stirring rod, and the spring installed on the trapezoidal pad at the bottom of the scraper can provide the scraper with the elasticity to return to its original position.

[0017] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention uses a traditional barrel-shaped reactor as a modular base and protective cover. After the hydraulic components are activated and extended, the operator needs to put the proportioned cable material into the slot at the top of the base. Then, the hydraulic components are lowered until the protective cover returns to its initial state. The proportioned cable material is continuously heat-melted by the hot air continuously discharged into the protective cover and the slot at the top of the base through the heat-spraying pipes. When the motor is activated and works with the track drive shaft, the pressure ring and multiple stirring rods installed outside the shaft will continuously stir the cable material in the slot at the top of the base. When the stirring rod passes through two symmetrically distributed scraper plates, the material adhering to the outside of the stirring rod will be scraped off by the scraper plates. When the wire is energized and the heating coil is heated, the scraper plates heated by the heat radiation will scrape off the material adhering to the outside of the stirring rod. This effectively avoids the interference of the heat-melted material with the material causing the rotation of the stirring rod, thus ensuring that the multiple stirring rods can rotate in a relatively clean state each time.

[0018] 2. This invention utilizes symmetrically distributed arc-shaped grooves on the outer wall of the top shell of the base. These grooves, in conjunction with the arc-shaped grooves on the top shell of the base, limit and clamp the linkage rack. At this time, the end of the linkage rack with the scraper installed on it will adhere and press against the inner wall of the slot on the top of the base. The outer arc-shaped rack of the linkage rack will rotate in a circular motion with the rotating transmission rocker. When the pin is removed, the fixed sealing pad will be withdrawn from the hole in the top shell of the base. At this time, the cable material that has been fully stirred in the slot on the top of the base will flow down the hole to the top of the guide plate and finally be discharged outward along the guide plate. As the transmission rocker rotates, the linkage rack driven by the transmission rocker can scrape off the material remaining on the inner wall of the shell, thereby effectively ensuring that the device will not cause the material to stick and interfere with the inner wall of the shell.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of an automatic cable material mixing machine provided by the present invention. Example 1:

[0024] Combination Figures 1-10 As shown, the present invention provides an automatic cable material mixing machine, including a melting mechanism 100, a stirring mechanism 200 installed in the melting mechanism 100, and an electric heating scraping mechanism 300 installed in the melting mechanism 100.

[0025] The melting mechanism 100 includes a material holding assembly 110, a hydraulic component 120, a protective cover 130, a heat-spraying pipe 140, a linkage rack 150, a transmission rocker arm 160, a partition 170, and trusses 180 and 190. The material holding assembly 110 also includes a base 111, a pad column 112, a motor 113, a track 114, a guide plate 115, a sealing pad block 116, and a pin 117. The stirring mechanism 200 includes a shaft 210, a pressure-bearing outer ring 220, and a stirring rod 230. The electric heating scraping mechanism 300 includes a vertical frame 310, a horizontal bar 320, a beam frame 330, a heat-insulating ceramic buckle 340, a positioning end rod 350, an insertion rod 360, a heating coil 370, a wire 380, and a spring 390.

[0026] Specifically, the hydraulic component 120 is fixed to the material holding assembly 110 using clamps; the protective cover 130 is located directly above the material holding assembly 110; the heat-spraying pipe 140 is fixedly installed on the protective cover 130; the linkage rack 150 is movably installed on the material holding assembly 110; the transmission rocker arm 160 of the transmission linkage rack 150 is movably installed inside the material holding assembly 110; multiple sets of partitions 170 are located inside the material holding assembly 110; the truss 180 is installed between the multiple sets of partitions 170; two pads 112 are installed at both ends of the bottom of the base 111; the motor 113 is installed in the transverse hole inside the base 111; the track 114 is driven by the shaft outside the motor 113; the guide plate 115 is movably connected to the clamps outside the housing of the base 111; the sealing pad 116 is movably installed inside the housing at the top of the base 111; and a pin 1 penetrates into the inside of the sealing pad 116. 17 is movably installed inside the base 111. The shaft 210 is movably installed inside the shell at the top of the base 111. Three pressure-bearing outer rings 220 are installed outside the shaft 210. Multiple stirring rods 230 are evenly installed on the outer wall of the pressure-bearing outer rings 220. Two vertical frames 310 are installed at both ends of the truss 180. The crossbar 320 is installed at the bottom of the vertical frame 310 with bolts. The beam frame 330 is installed in the middle of the vertical frame 310. Three heat-insulating ceramic buckles 340 are evenly installed on the beam frame 330. The positioning end rod 350 is movably installed inside the heat-insulating ceramic buckle 340. The insertion rod 360 is inserted into the heat-insulating ceramic buckle 340 and the positioning end rod 350. The heating coil 370 located outside the positioning end rod 350 is connected inside the heat-insulating ceramic buckle 340. The wire 380 is connected to the three heating coils 370. Three springs 390 are evenly installed at three ends on the inner side of the crossbar 320.

[0027] The proportioned cable material is fed into the slot at the top of the base 111. The hydraulic component 120 is then lowered until the protective cover 130 returns to its initial state. Hot air is continuously discharged through the heat pipe 140 into the protective cover 130 and the slot at the top of the base 111, continuously melting the proportioned cable material. When the motor 113 starts and works in conjunction with the drive shaft 210 via the track 114, the pressure-bearing outer ring 220 and multiple stirring rods 230 mounted outside the shaft 210 continuously stir the cable material in the slot at the top of the base 111. When the stirring rods 230 pass two symmetrically distributed scraper plates, the material adhering to the outside of the stirring rods 230 is scraped off. When the conductor 380 is energized and the heating coil 370 heats up, the scraper plates, heated by heat radiation, further remove the material adhering to the outside of the stirring rods 230. The material in the part is scraped off, which can effectively prevent the hot melted and sticky material from interfering with the rotation of the stirring rod 230. This ensures that the multiple stirring rods 230 can rotate in a relatively clean state each time. The outer arc-shaped rack of the linkage rack 150 will rotate in a circle with the rotating transmission rocker arm 160. When the pin 117 is removed, the fixed sealing pad 116 will be removed from the hole in the top shell of the base 111. At this time, the cable material that has been fully stirred in the top slot of the base 111 will flow down the hole to the top of the guide plate 115 and finally be discharged outward along the guide plate 115. As the transmission rocker arm 160 rotates, the linkage rack 150 driven by the transmission rocker arm 160 can scrape off the material remaining on the inner wall of the shell, which can effectively ensure that the device will not cause the material to stick and interfere with the inner wall of the shell. Example 2:

[0028] Combination Figures 3-9 As shown, based on Embodiment 1, trapezoidal slots are provided on both sides of the base 111, and ventilation slots are provided on the inner wall of the trapezoidal slots. A rectangular groove is provided on the top of the guide plate 115, and the top of the guide plate 115 is located directly below the hole in the shell of the base 111. The two ends of the heat spray pipe 140 are respectively equipped with symmetrically distributed flow guide pipes. The linkage rack 150 has an overall arc-shaped structure, and a scraper is installed on the top of the linkage rack 150. The inner wall of the linkage rack 150 is equipped with evenly distributed tooth blocks. Two gear ends that mesh with the tooth blocks on the inner wall of the linkage rack 150 are installed on the transmission rocker arm 160.

[0029] By fixing the motor 113 in the transverse hole on the outside of the base 111, and using the ventilation slots on the trapezoidal slots on both sides of the base 111 for heat dissipation of the motor 113, the fixed motor 113 can be safely protected when it runs continuously and drives the track 114 and shaft 210 to rotate at high speed. At the same time, it can also ensure that the pressure-bearing outer ring 220 on the shaft 210 and the stirring rod 230 can fully stir the cable material that has been molten in the top shell of the base 111, while the heat spray pipe 140 is also heated. Both ends of the guide pipe extend into the interior of the protective cover 130. When the external heat pipe delivers the hot air along the heat spray pipe 140 into the interior of the protective cover 130, the cable material stored in the top shell of the base 111 will be continuously heated until softened in the encapsulated state. As the transmission rocker arm 160 rotates, the gear end on the transmission rocker arm 160 will drive the linkage rack 150 to slide in a circle. The scraper installed on the linkage rack 150 can effectively scrape off the material adhering to the inner wall of the top shell of the base 111. Example 3:

[0030] Combination Figures 8-10 As shown, based on Embodiment 1, the heat-insulating ceramic buckle 340 is made of ceramic material, and the inner end of the heat-insulating ceramic buckle 340 is provided with a cylindrical hole. The inner end of the positioning rod 350 is equipped with a scraper, and the bottom of the scraper is equipped with a trapezoidal pad.

[0031] By installing the heat-insulating ceramic buckle 340 on the beam frame 330, and using the heat-insulating ceramic buckle 340 to fix the heating coil 370, and using the positioning end rod 350 to fix the scraper, when the wire 380 is energized, the heating coil 370 can continuously release heat. The heat energy radiated to the scraper can soften and scrape off the material adhering to the outside of the stirring rod 230. After the cylindrical end of the positioning end rod 350 away from the heat-insulating ceramic buckle 340 is inserted into the inside of the scraper, the fixed scraper can stably scrape the stirring rod 230. The spring 390 installed on the trapezoidal pad at the bottom of the scraper can provide the scraper with the elasticity to return to its original position.

[0032] The working principle and usage process of this invention are as follows: Multiple stirring rods 230 are pre-welded evenly to the outer wall of the pressure-bearing outer ring 220. At this time, the three pressure-bearing outer rings 220 are fixed at equal intervals to the outside of the shaft 210. Then, the positioning end rod 350 is movably installed inside the heat-insulating ceramic buckle 340 using the insertion rod 360 for positioning and insertion. The cylindrical end of the other end of the positioning end rod 350 presses against the scraper plate at the outer end of the heating coil 370. Next, the beam frame 330 is used to fix three adjacent heat-insulating ceramic buckles 340. At this time, the beam frame 330 is fixed by the vertical frame 310, and the horizontal rod 320 is fixed with bolts to the grooves at both ends of the bottom of the vertical frame 310. Three springs 3 are connected to the three ends on the inner side of the horizontal rod 320. 90, and the other end of the three springs 390 is fixedly connected to the bottom end of the three adjacent scraper plates. Then, the two assembled vertical frames 310 are respectively installed at both ends of the truss 180. Then, the linkage rack 150 is assembled along the sliding groove of the semi-circular shell at the top of the base 111 until the teeth on the bottom end of the linkage rack 150 mesh with the two gear ends on the transmission rocker arm 160. The transmission end of the shaft 210 that extends to the outside of the base 111 is connected to the auxiliary end of the motor 113 by the track 114. Then, the two guide rods at the top end of the guide plate 115 are movably installed in the clamp on the outer wall of the base 111. At this time, the guide plate 115 is supported by the top of the pad column 112, and the sealing pad Block 116 is assembled into the discharge slot inside the base 111 via pin 117. Three sets of partitions 170 are evenly installed on the outside of the shaft 210, and adjacent partitions 170 will position and clamp the pressure-bearing outer ring 220 and the combined multiple stirring rods 230. In use, the operator needs to control the hydraulic rod inside the hydraulic component 120 to lift upwards until the protective cover 130 and the material holding assembly 110 unfold. Then, PVC and other proportioned raw materials are put into the slot at the top of the base 111. Then, the hydraulic component 120 is controlled to return to the initial state. At this time, the protective cover 130 will seal the slot at the top of the base 111. As the hot air flows through the heat spray pipe 140 towards the protective cover 130 and the base... When the material is continuously conveyed within the cavity between 111, the raw material fed into the top slot of the base 111 will be melted. Then, the motor 113 is started and run. At this time, the shaft 210 driven by the track 114 will drive the pressure outer ring 220 and multiple stirring rods 230 to mix the melted raw material. Multiple scraper plates arranged in an array will continuously scrape off the material remaining on the multiple stirring rods 230. When the raw material is fully mixed, the operator can remove the pin 117. At this time, the sealing pad 116 will be removed from the inside of the base 111, and the raw material in the top slot of the base 111 can be transferred outward along the guide plate 115, thereby avoiding the cable material from sticking and interfering with the inner wall of the reaction equipment during the mixing process.

[0033] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
