Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an anti-clogging feeding device for a cable extruder. Background Technology

[0002] In the cable manufacturing industry, the cable extruder is one of the core pieces of equipment, and the performance of its feeding device directly affects the quality and production efficiency of the extruded cable. Traditional cable extruder feeding devices typically consist of a simple hopper and screw feeding structure.

[0003] In actual production, numerous problems arise. On the one hand, the form and properties of raw materials are quite complex and diverse; for example, some plastic granules may be uneven in size and irregular in shape. When these raw materials enter the feeding device, they are prone to accumulation and blockage at the bottom outlet of the hopper or the screw feed section. Once blockage occurs, it not only leads to interruption of material supply, forcing production to stop and causing a significant reduction in production efficiency, but also the process of clearing blockages is time-consuming and labor-intensive, increasing labor costs and equipment downtime for maintenance.

[0004] Therefore, there is an urgent need for a new type of anti-clogging feeding device for cable extruders, which can effectively solve the above problems, improve the quality and efficiency of cable production, and adapt to the development trend of the industry. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an anti-clogging feeding device for a cable extruder.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A clogging-proof feeding device for a cable extruder includes a hopper, an auxiliary hopper on the top of the side wall of the hopper, a support base on the top of the outer wall of the hopper, a support rod on the top wall of the support base, a connecting seat on the top wall of the support rod, a hydraulic telescopic cylinder on the right side of the outer wall of the connecting seat, a top seat on the driving bottom wall of the hydraulic telescopic cylinder, bases on both sides of the bottom wall of the top seat via connecting rods, a motor on the center of the top wall of the base, and a unclogging mechanism rotatably connected to the bottom wall of the base.

[0008] Furthermore, the unblocking mechanism includes a rotating rod, the outer wall of which is rotatably connected to the bottom wall of the base via a bearing, the top wall of which is fixedly connected to the output end of the motor via a coupling, a blade I is provided on the outer wall of the rotating rod, a baffle plate is provided on the outer wall of the rotating rod below the blade I, and a second blade is provided on the outer wall of the rotating rod below the baffle plate.

[0009] Furthermore, a through hole is provided on the outer wall of the blade.

[0010] Furthermore, the outer ring of the bearing is fixedly connected to the outer wall of the base through the bearing seat, and the inner ring of the bearing is interference-fitted to the outer wall of the rotating rod.

[0011] Furthermore, the inner cavities of the auxiliary hopper and the hopper are connected.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes a dredging mechanism installed inside the hopper, which uses a motor-driven rotating rod to rotate blades one and two, to stir and dredge materials with complex shapes and properties. This effectively prevents the accumulation and blockage of materials at the bottom outlet of the hopper or the screw feed section, greatly reducing the risk of material supply interruption, ensuring the continuity of the cable production process, significantly improving production efficiency, and reducing downtime and production delays caused by blockages.

[0014] By using a hydraulic telescopic cylinder to drive the baffle plate to move up and down, the distance between the baffle plate and the inner wall of the hopper can be flexibly and precisely controlled, thereby achieving precise control of the material feeding speed. This feature ensures that the raw materials enter the extruder at an accurate ratio and a stable speed under different production process requirements, especially when changing the cable raw material formula. This effectively improves the stability and consistency of cable product quality and reduces the risk of product quality defects caused by inaccurate raw material mixing ratios.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-2 As shown, an anti-clogging feeding device for a cable extruder includes a hopper 1, an auxiliary hopper 2 on the top of the side wall of the hopper 1, a support seat 3 on the top of the outer wall of the hopper 1, a support rod 4 on the top wall of the support seat 3, a connecting seat 5 on the top wall of the support rod 4, a hydraulic telescopic cylinder 6 on the right side of the outer wall of the connecting seat 5, a top seat 7 on the driving bottom wall of the hydraulic telescopic cylinder 6, bases 9 on both sides of the bottom wall of the top seat 7 via connecting rods 8, a motor 15 in the middle of the top wall of the base 9, and a dredging mechanism rotatably connected to the bottom wall of the base 9.

[0022] Furthermore, the unblocking mechanism includes a rotating rod 10. The outer wall of the rotating rod 10 is rotatably connected to the bottom wall of the base 9 via a bearing. The top wall of the rotating rod 10 is fixedly connected to the output end of the motor 15 via a coupling. A blade 11 is provided on the outer wall of the rotating rod 10. A baffle plate 13 is provided on the outer wall of the rotating rod 10 below the blade 11. A blade 14 is provided on the outer wall of the rotating rod 10 below the baffle plate 13. The motor 15 causes the rotating rod 10 to rotate, thereby rotating the blade 11, the baffle plate 13, and the blade 14. The rotation of the blade 11 and the blade 14 stirs and unblocks the material, preventing blockage during the material feeding process.

[0023] Furthermore, a through hole 12 is provided on the outer wall of the blade 11 to reduce the resistance when the blade 11 rotates, thereby reducing the load on the motor 15.

[0024] Furthermore, the outer ring of the bearing is fixedly connected to the outer wall of the base 9 through the bearing seat, and the inner ring of the bearing is interference-fitted to the outer wall of the rotating rod 10. The bearing fixes the rotating rod 10, making it easier for the rotating rod 10 to rotate through the bearing.

[0025] Furthermore, the inner cavities of the auxiliary hopper 2 and the feed hopper 1 are connected, and the unblocking mechanism occupies the space above the feed hopper 1. Materials can be added into the feed hopper 1 through the auxiliary hopper 2.

[0026] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0027] One specific application of this embodiment is:

[0028] In use, the specially designed unblocking mechanism is cleverly placed in the space above the hopper 1. When materials need to be added, various materials can be conveniently added into the feed hopper 1 through the auxiliary hopper 2. When the motor 15 is turned on, the power generated will cause the rotating rod 10 to rotate stably, which in turn drives the connected blade 11, baffle 13 and blade 2 14 to rotate synchronously. During this process, blade 11 and blade 2 14, with their unique shape and rotation, apply an effective stirring force to the materials in the hopper, so that the materials are always in a loose and smooth flow state, thus successfully preventing the accumulation and blockage of materials during the feeding process, and ensuring that the materials can be continuously and stably conveyed to the screw area of ​​the extruder.

[0029] The hydraulic telescopic cylinder 6 begins to perform its crucial driving function, precisely driving the top seat 7 to move linearly up and down. The top seat 7 is tightly connected to the base 9 via the connecting rod 8. The rotating rod 10, motor 15, blade one 11, baffle plate 13, and blade two 14 are all mounted on the base 9. Therefore, when the top seat 7 moves up and down, it drives this series of components to move synchronously up or down. When the baffle plate 13 is driven to move upward, the gap between the baffle plate 13 and the inner wall of the hopper 1 gradually increases. At this time, the channel through which the material passes under its own gravity widens, and the feeding speed will increase accordingly. Conversely, when the baffle plate 13 is driven to move downward, the distance between the baffle plate 13 and the inner wall of the hopper 1 gradually decreases, the channel through which the material passes narrows, and the feeding speed slows down accordingly. By precisely controlling the up and down position of the baffle plate 13, flexible and precise control of the material feeding speed can be achieved to meet the diverse needs of different production processes and material characteristics for feeding speed, providing a solid and reliable guarantee for the efficient and stable operation of the cable extrusion production process.

Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
