Description

Technical Field

[0001] This application relates to the field of cable raw material processing equipment, and in particular to an easy-to-clean automatic push-pull type double cone feeder. Background Technology

[0002] In the cable manufacturing industry, the double cone feeder is a key piece of equipment in the mixing, proportioning, and conveying processes. It is mainly used to stably and uniformly supply various raw materials such as PVC plastic granules and masterbatches to the extruder. Existing double cone feeders typically include a hopper and two horizontally placed, rotating cones installed inside the hopper. The hopper is equipped with a motor that drives the cones to rotate. The helical surfaces of the cones push the material from the center of the hopper to both sides or from both sides to the center, thereby achieving uniform feeding.

[0003] However, because the two cones are horizontally fixed inside the material cart, the gap between the cones and the inner wall of the hopper, especially between the bottom of the cones and the bottom shell of the hopper, is extremely narrow. When changing material types or performing routine maintenance, residual material easily accumulates and adheres to this narrow area. Operators find it difficult to reach their arms or cleaning tools into this area for thorough cleaning, often requiring the use of long-handled tools for blind cleaning, which is ineffective and inefficient. In some cases, it even requires extensive disassembly of the entire equipment, which is time-consuming and labor-intensive, severely impacting production efficiency and operational continuity. Improvements are needed. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an easy-to-clean automatic push-pull type double cone feeder.

[0005] The automatic push-pull type double cone feeder that is easy to clean, as provided in this application, adopts the following technical solution: An easy-to-clean automatic push-pull type double cone feeder includes a main unit, a cone body, and a hopper. The main unit is equipped with a slide rail, and the hopper is slidably mounted on the slide rail and detachably connected to the main unit through a connecting component. The cone body is rotatably mounted on the main unit, and the main unit is equipped with a motor for driving the cone body to rotate. The hopper has an installation port on one side for inserting the cone body. When the connecting assembly is connected, the hopper is in the working position and the cone body extends into the hopper through the installation port. When the connecting assembly is released, the hopper can be pulled out along the slide rail away from the main unit, so that the cone body is separated from the inner cavity of the hopper.

[0006] By adopting the above technical solution, the hopper is pulled out entirely along the slide rail, completely separating it from the cone. This allows operators to access the inner wall of the hopper and the surface of the cone from all angles. Whether it's adhering residual material or clumps, they can be easily and thoroughly removed, solving the fundamental problem of traditional equipment arms and tools being unable to reach narrow, dead-end areas.

[0007] Optionally, the connecting assembly includes a bolt, the hopper has a first threaded hole, and the main unit has a second threaded hole that is directly opposite to the first threaded hole; the bolt engages with the first threaded hole and the second threaded hole, and the head of the bolt abuts against the outer wall of the hopper.

[0008] By adopting the above technical solution, the hopper and the main unit can be fixed by the cooperation of bolts and threaded holes. The structure is simple and easy for workers to assemble.

[0009] Optionally, the head of the bolt is provided with a rubber layer, which is used to abut against the outer wall of the hopper.

[0010] By adopting the above technical solution, the rubber layer can prevent the bolts from making hard contact with the surface of the silo, thus preventing wear on the silo.

[0011] Optionally, the connecting assembly includes a plug rod, a locking member, and a nut. The hopper and the main unit are respectively provided with a first positioning hole and a second positioning hole that are coaxially opposite each other. The plug rod is used to plug into the first positioning hole and the second positioning hole, and the locking member is used to fix the end of the plug rod to the main unit. The nut is sleeved on the outer wall of the plug rod, and the outer wall of the plug rod is provided with a threaded part for threaded engagement with the nut. When the locking member fixes the plug rod to the main unit, the nut initially abuts against the outer wall of the hopper.

[0012] By adopting the above technical solution, the plug-in rod can be quickly connected to the main unit through the locking component. At this time, the nut initially abuts against the outer wall of the hopper. Subsequently, the nut can be tightened to press the hopper and the main unit together, which can increase the stability of the connection between the main unit and the hopper. This structure can avoid tightening the connecting components multiple times, further improving the efficiency of disassembly and assembly.

[0013] Optionally, the locking component includes a positioning rod and a spring. The outer wall of the main unit has a movable groove that communicates with the second positioning hole. The positioning rod is movably installed in the movable groove. The plug-in rod has a positioning groove for the positioning rod to be inserted into. A mounting plate is provided at the end of the positioning rod away from the main unit. The spring is sleeved on the outer wall of the positioning rod. The two ends of the spring are respectively connected to the mounting plate and the main unit. The elastic force of the spring is used to drive the positioning rod to move toward one side of the second positioning hole.

[0014] By adopting the above technical solution, when it is necessary to connect the plug-in rod to the main unit, the operator inserts the plug-in rod into the first positioning hole and the second positioning hole, and then pulls the positioning rod to drive it to engage with the positioning groove, thereby improving the connection efficiency between the plug-in rod and the main unit and simplifying the operation steps.

[0015] Optionally, the outer wall of the plug rod is provided with a limiting block, and the inner wall of the first positioning hole is provided with a limiting groove for the limiting block to be inserted.

[0016] By adopting the above technical solution, the insertion and connection of the limiting block and the limiting groove can make the positioning rod and the positioning groove face each other, thereby improving the installation efficiency of the insertion rod and the main unit.

[0017] Optionally, a bellows is provided between the mounting plate and the main unit, and the spring is located inside the bellows.

[0018] By adopting the above technical solution, when a bellows is installed between the mounting plate and the main unit and the spring is located inside the bellows, the spring can be protected, preventing it from being damaged by external factors and extending its service life.

[0019] Optionally, a reinforcing block is provided on one side of the main unit, and the hopper has a reinforcing groove for the reinforcing block to be inserted.

[0020] By adopting the above technical solution, the reinforcing block is inserted into the reinforcing groove, which can enhance the stability of the connection between the hopper and the main unit, and further ensure the stability of the feeder during operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By pulling the hopper out along the slide rail as a whole, completely separating it from the cone, operators can easily clean the cone and the inside of the hopper. This avoids the problem of difficult cleaning due to the narrow gaps in traditional double cone feeders, improving cleaning efficiency and effectiveness, and reducing the workload of disassembling the equipment.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] Example 1: This application discloses an easy-to-clean automatic push-pull type double cone feeder.

[0025] Reference Figure 1 An easy-to-clean automatic push-pull type double cone feeder includes a main unit 1, a cone 2, and a hopper 3. The cone 2 is generally made of cast iron or cast steel, which has high strength and wear resistance. The spiral surface of the cone 2 is precision machined to ensure uniform material feeding.

[0026] Two sets of cone bodies 2 are provided, and the two sets of cone bodies 2 are rotatably mounted on the main unit 1. The main unit 1 is equipped with a motor, and gears are provided at the ends of the two cone bodies 2. The two gears mesh with each other. The motor is mounted on the main unit 1 and is used to drive one of the gears to rotate. When the motor is started, the two gears can be rotated, thereby enabling the two cone bodies 2 to rotate relative to each other.

[0027] A slide rail 11 is provided on one side of the main unit 1. The slide rail 11 is generally made of high-strength steel and its surface is treated with quenching to improve its wear resistance and hardness. A slide block 31 is provided at the bottom of the hopper 3, and the slide block 31 slides and engages with the slide rail 11. The slide block is fixed to the bottom of the hopper 3 by bolts or welding to ensure a firm connection between it and the hopper 3. The hopper 3 is detachably connected to the main unit 1 through a connecting component 4, so that the hopper 3 can be stably connected to the main unit 1 for operation, and can also be separated from the main unit 1 when needed.

[0028] Reference Figure 2 The hopper 3 has an installation port 33 on one side for inserting the cone 2. When the connecting component 4 is connected, the trolley is in the working position, and the cone 2 extends into the hopper 3 through the installation port 33. The cone 2 can then push materials in the hopper 3 to achieve uniform feeding. When the connecting component 4 is released, the hopper 3 can be pulled out along the slide rail 11 to the side away from the host 1, so that the cone 2 is separated from the inner cavity of the hopper 3.

[0029] Reference Figure 1 In this embodiment, the connecting component 4 includes a bolt. The head of the bolt can be a hexagonal head or a round head. A hexagonal head is convenient for tightening and disassembling with tools such as a wrench; a round head is more aesthetically pleasing and can prevent scratching operators in some cases.

[0030] The hopper 3 has a first threaded hole 32, and the main unit 1 has a second threaded hole 13 that is directly opposite to the first threaded hole 32; the bolt is engaged with the first threaded hole 32 and the second threaded hole 13, and the head of the bolt abuts against the outer wall of the hopper 3.

[0031] To increase the contact area and sealing between the bolts and the outer wall of silo 3, a rubber layer is provided on the bolt head. The rubber layer can be natural rubber or synthetic rubber. Natural rubber has better elasticity and flexibility, while synthetic rubber has better aging resistance and wear resistance. The rubber layer is fixed to the bolt head by means of adhesive or other methods. When the bolt is tightened, the rubber layer fits tightly against the outer wall of silo 3, preventing loosening and reducing the possibility of scratches on the outer wall of silo 3.

[0032] Reference Figure 2 In addition, a reinforcing block 16 is provided on one side of the main unit 1, and a reinforcing groove 36 is provided in the hopper 3 for the reinforcing block 16 to be inserted. The reinforcing block 16 and the reinforcing groove 36 can increase the stability of the connection between the main unit 1 and the hopper 3. The reinforcing block 16 is generally cuboid or cube-shaped and is made of high-strength materials such as steel.

[0033] The implementation principle of Embodiment 1 of this application is as follows: In operation, the hopper 3 is connected to the main unit 1 via bolts. The motor drives the cone 2 to rotate, and the spiral surface of the cone 2 pushes the material into the hopper 3, achieving uniform feeding. When cleaning is required, the bolts are loosened, and the hopper 3 can slide away from the main unit 1 along the slide rail 11, separating the cone 2 from the inner cavity of the hopper 3. This allows operators to easily clean the cone 2 and the inside of the hopper 3, avoiding the problem of difficult cleaning due to the narrow gap in traditional double cone feeders, improving cleaning efficiency and effectiveness, and reducing the workload of disassembling the equipment.

[0034] Example 2: This application discloses an easy-to-clean automatic push-pull type double cone feeder.

[0035] Reference Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that the connecting component 4 includes a plug rod 41, a locking member 42, and a nut 43. The plug rod 41 is generally made of aluminum alloy or steel. The plug rod 41 made of aluminum alloy is lightweight and corrosion resistant; the plug rod 41 made of steel has high strength. The hopper 3 has a first positioning hole 34, and the main unit 1 has a second positioning hole 14 that is directly opposite to the first positioning hole 34. The plug rod 41 is used to plug into and cooperate with the first positioning hole 34 and the second positioning hole 14, and the locking member 42 is used to fix the inner wall of the second positioning hole 14 at the end of the plug rod 41.

[0036] Reference Figure 4The locking component 42 includes a positioning rod 421 and a spring 422. The end of the positioning rod 421 away from the main unit 1 is provided with a mounting plate 423. The outer wall of the main unit 1 is provided with a movable groove 15 that communicates with the second positioning hole 14. The positioning rod 421 is movably installed in the movable groove 15. The plug rod 41 is provided with a positioning groove 46 for the positioning rod 421 to be inserted. The spring 422 is sleeved on the outer wall of the positioning rod 421. The two ends of the spring 422 are respectively connected to the mounting plate 423 and the main unit 1. The elastic force of the spring 422 is used to drive the positioning rod 421 to move toward one side of the second positioning hole 14.

[0037] To further ensure positioning accuracy, a limiting block 45 is provided on the outer wall of the plug-in rod 41, and a limiting groove 35 is provided on the inner wall of the first positioning hole 34 for the limiting block 45 to be inserted. The limiting block 45 and the limiting groove 35 can be rectangular, trapezoidal, or other shapes. Through the cooperation of the limiting block 45 and the limiting groove 35, the plug-in rod 41 can be prevented from rotating during insertion, ensuring accurate positioning.

[0038] To protect the spring 422, a bellows (not shown in the figure) is provided between the mounting plate 423 and the main unit 1, and the spring 422 is located inside the bellows. The bellows can be a metal bellows or a plastic bellows. Metal bellows have high strength; plastic bellows are lightweight and corrosion-resistant.

[0039] Nut 43 is sleeved on the outer wall of plug rod 41, and the outer wall of plug rod 41 is provided with threaded part 44 for threaded engagement with nut 43; when positioning rod 421 is inserted into positioning groove 46, nut 43 initially abuts against outer wall of hopper 3, and then nut 43 is rotated to make it abut against outer wall of hopper 3, thereby increasing the stability of hopper 3 and main unit 1 installation.

[0040] The implementation principle of Embodiment 2 of this application is as follows: By interlocking the positioning rod 421 with the positioning slot 46, the insertion rod 41 can be quickly connected to the main unit 1. At this time, the nut 43 initially abuts against the outer wall of the hopper 3. Subsequently, the nut 43 can be tightened to press the hopper 3 tightly against the main unit 1, which can increase the stability of the connection between the main unit 1 and the hopper 3. This structure further improves the disassembly efficiency of the hopper 3 and the main unit 1 and avoids repeatedly tightening the bolts to press the hopper 3 tightly against the main unit 1.

[0041] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
