Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, specifically a raw material screening device for producing cable insulation layer materials. Background Technology
[0002] Cable insulation is an indispensable component of cable structure. Its main function is to isolate the wires to prevent electric shock and ensure the safe transmission of electrical energy. It is typically made of specific insulating materials that are voltage-resistant, capable of withstanding various voltage levels that the cable may encounter during use.
[0003] Traditional raw material screening methods often have numerous drawbacks, failing to meet the demands of modern industry for high-precision and high-efficiency production. Many screening devices lack a precise and stable power transmission system to drive the screening components. This results in insufficient movement of raw materials within the screening container, often leading to accumulation and stagnation. Consequently, the raw materials cannot fully contact the screening structure, significantly impacting the comprehensiveness and accuracy of the screening. This can easily result in substandard raw materials being mixed into subsequent production stages, reducing product quality. Furthermore, most methods can only achieve simple, coarse screening, unable to perform detailed grading based on the precise particle size requirements of the raw materials. Utility Model Content
[0004] The purpose of this invention is to provide a raw material screening device for producing cable insulation materials, which solves the problem of accumulation and stagnation caused by the lack of a precise and stable power transmission system to drive the screening, and achieves the purpose of facilitating detailed screening.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for producing cable insulation layer materials, comprising a base plate, a side plate one and a side plate two fixedly installed on the top of the base plate, the side plate one and the side plate two being symmetrically arranged, a controller being arranged on the outer side of the side plate one, a receiving box being equidistantly arranged on the top of the base plate, a screening component being arranged between the side plate one and the side plate two, and a dust suction component being arranged on the top of the screening component.
[0006] Preferably, the screening component includes: a protective outer cylinder, fixedly installed between side plate one and side plate two; motor one, fixedly installed on the outside of side plate one; and motor two, fixedly installed on the outside of side plate two.
[0007] Preferably, a screening inner cylinder is movably arranged inside the protective outer cylinder. One end of the screening inner cylinder is connected to a connecting cylinder. The other end of the connecting cylinder movably passes through the inner wall of the protective outer cylinder and the inner side of the first side plate, and extends to the outer side of the first side plate. It is rotatably connected to the first side plate and the protective outer cylinder respectively through bearings. A feed pipe is rotatably connected inside the connecting cylinder through bearings. The feed pipe is connected to the screening inner cylinder. The feed pipe is fixedly connected to the first side plate through a fixing bracket. A gear is fixedly sleeved on the outer wall of the connecting cylinder.
[0008] The connecting cylinder is rotatably connected to the side plate and the protective outer cylinder through bearings. This stable connection method ensures the stability of the inner screening cylinder when screening raw materials at high speed.
[0009] Preferably, the output end of the motor is provided with a short shaft, which is rotatably connected to the side plate via a bearing. A gear is fixedly sleeved on the outside of the short shaft, and the gear meshes with the gear. A discharge funnel is uniformly connected to the bottom of the protective outer cylinder. The outer wall of the screening inner cylinder is provided with screening holes one, two, and three at equal intervals around its circumference. Screening hole one is smaller than screening hole two, and screening hole three is larger than screening hole two. The top of the discharge funnel is in contact with the outer wall of the screening inner cylinder.
[0010] The outer wall of the inner cylinder is equipped with three screening holes, namely screening hole one, screening hole two, and screening hole three, arranged in an orderly manner with varying diameters, thus constructing a multi-stage screening system.
[0011] Preferably, the output end of the second motor is provided with a long shaft, the other end of which movably passes through the outer side of the second side plate, the other side of the outer wall of the protective outer cylinder, the outer wall of the screening inner cylinder and extends into the interior of the screening inner cylinder, and is rotatably connected to the first side plate, the protective outer cylinder and the screening inner cylinder respectively through bearings. The outer wall of the long shaft is fixedly fitted with a spiral blade, which is disposed inside the screening inner cylinder.
[0012] The special design of the spiral blades makes the movement trajectory of the raw materials inside the screening cylinder more regular and controllable. Compared with simply relying on the rotation of the cylinder, it can guide the raw materials to pass through the screening holes of different diameters sequentially and evenly, ensuring that every grain of raw material has a sufficient opportunity to participate in the screening, and avoiding screening omissions or unevenness caused by poor local flow of raw materials.
[0013] Preferably, the dust collection assembly includes a dust collection hood, which is connected to the top of the protective outer cylinder.

[0015] The symmetrically connected suction pipes at the top of the dust hood, along with the connecting horizontal and vertical pipes, create a comprehensive and efficient dust collection network. This layout maximizes coverage of the raw material screening area, ensuring that dust generated during the screening process can be quickly captured regardless of its direction.
[0016] This utility model provides a raw material screening device for producing cable insulation materials. It has the following features:
[0017] Beneficial effects:
[0018] (1) When the motor is started, the short shaft rotates and the gear on the short shaft rotates accordingly. Since the gear is meshed with the gear on the outer wall of the connecting cylinder, the connecting cylinder rotates, which in turn drives the inner screening cylinder connected to it to rotate. The rotation of the inner screening cylinder causes the raw material to roll and move inside the cylinder, ensuring that the raw material can fully contact the cylinder wall, so as to ensure that the entire screening process can proceed in an orderly manner, prevent accumulation and blockage, and prepare for subsequent screening.
[0019] (2) This utility model starts the second motor, which drives the long shaft to rotate. The spiral blades on the long shaft rotate inside the screening cylinder, pushing the raw material to move towards the discharge end. During the movement, the smaller particles of raw material pass through screening hole one, screening hole two, and screening hole three in sequence according to their particle size. The raw material with a particle size smaller than screening hole one passes through first and falls into the corresponding discharge funnel. The raw material with a particle size between screening hole one and screening hole two passes through screening hole two and falls into the corresponding discharge funnel. This process is repeated to achieve the effect of accurately classifying and screening the raw material according to its particle size. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] Addressing the current problem of insufficient and unstable power transmission systems for driving the screening process, leading to accumulation and stagnation that prevent thorough screening, this invention provides a preferred embodiment of a raw material screening device for producing cable insulation materials. Figure 1-4As shown: A raw material screening device for producing cable insulation material includes a base plate 1, with side plates 2 and 3 fixedly installed on the top of the base plate 1. The side plates 2 and 3 are symmetrically arranged. A controller 4 is arranged on the outer side of side plate 2. A receiving box 5 is equidistantly arranged on the top of the base plate 1. A screening assembly 6 is arranged between side plates 2 and 3. A dust collection assembly 7 is arranged on the top of the screening assembly 6. The screening assembly 6 includes: a protective outer cylinder 611, fixedly installed between side plates 2 and 3; a motor 616, fixedly installed on the outer side of side plate 2; and a second motor 616. 6111 is fixedly installed on the outside of side plate 2 3; a screening inner cylinder 612 is movably arranged inside the protective outer cylinder 611. One end of the screening inner cylinder 612 is connected to a connecting cylinder 613. The other end of the connecting cylinder 613 movably passes through the inner wall of the protective outer cylinder 611 and the inner side of side plate 2, and extends to the outer side of side plate 2. It is rotatably connected to side plate 2 and protective outer cylinder 611 respectively through bearings. A feed pipe 614 is rotatably connected inside the connecting cylinder 613 through bearings. The feed pipe 614 is connected to the screening inner cylinder 612. The feed pipe 614 is connected to the side plate 2 through a fixing bracket. The first plate 2 is fixedly connected. Gear 615 is fixedly sleeved on the outer wall of the connecting cylinder 613. A short shaft 617 is provided at the output end of the motor 616. The short shaft 617 is rotatably connected to the side plate 2 through a bearing. Gear 618 is fixedly sleeved on the outer side of the short shaft 617. Gear 618 meshes with gear 615. The bottom of the protective outer cylinder 611 is uniformly connected with a discharge funnel 619. The outer wall of the screening inner cylinder 612 is provided with screening holes 1, 2, and 3 equidistantly spaced around the circumference. Screening hole 1 is smaller than screening hole 2, and screening hole 3 is larger than screening hole 3. Hole 2, the top of the discharge funnel 619 contacts the outer wall of the screening inner cylinder 612. The output end of motor 2 6111 is provided with a long shaft 6112. The other end of the long shaft 6112 movably passes through the outer side of side plate 2 3, the other side of the outer wall of the protective outer cylinder 611, and the outer wall of the screening inner cylinder 612 and extends into the interior of the screening inner cylinder 612. It is rotatably connected to side plate 1 2, protective outer cylinder 611 and screening inner cylinder 612 respectively through bearings. The outer wall of the long shaft 6112 is fixedly sleeved with a spiral blade 6113, which is located inside the screening inner cylinder 612.
[0031] Furthermore, in this embodiment, the motor 616 is started, driving the short shaft 617 to rotate. The gear 618 on the short shaft rotates accordingly. Since the gear 618 meshes with the gear 615 on the outer wall of the connecting cylinder 613, the connecting cylinder 613 rotates, which in turn drives the screening inner cylinder 612 connected to it to rotate. The rotation of the screening inner cylinder causes the raw material to tumble and move inside the cylinder, ensuring that the raw material can fully contact the cylinder wall to prepare for subsequent screening. As the screening inner cylinder 612 rotates, the screening holes of different diameters on its outer wall play their role. The motor 6111 operates synchronously, driving the long shaft 6112 to rotate. The spiral blades 6113 on the long shaft rotate inside the screening inner cylinder, pushing the raw material to move towards the discharge end. During the movement, smaller particles of raw material are screened sequentially through screening hole 1, screening hole 2, and screening hole 3 according to their particle size.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the raw material screening device for producing cable insulation layer materials provided by this utility model is as follows: Figure 1-4 As shown: The dust collection assembly 7 includes: a dust collection hood 711, which is connected to the top of the protective outer cylinder 611; a dust collection pipe 712 is symmetrically connected to the top of the dust collection hood 711, and a connecting horizontal pipe 713 is connected to the other end of the dust collection pipe 712. A connecting vertical pipe 714 is connected to the bottom of the connecting horizontal pipe 713, and a filter cylinder 715 is connected to the bottom of the connecting vertical pipe 714. A suction pump 717 is connected to the bottom of the filter cylinder 715 through a dust outlet pipe 716. The filter cylinder 715 has a filter layer 718, a fine filter layer 719, and an activated carbon base layer 7111 respectively. The fine filter layer 719 is located directly below the filter layer 718, and the activated carbon base layer 7111 is located directly below the fine filter layer 719.
[0034] Furthermore, in this embodiment, the suction pump 717 is activated to generate suction. Dust-laden air enters the filter cartridge 715 from the dust collection hood through the suction pipe 712, the connecting horizontal pipe 713, and the connecting vertical pipe 714. Inside the filter cartridge, the air first passes through the filter layer 718, which initially filters out larger dust particles. Then, the fine filter layer 719 further intercepts fine dust. Finally, the activated carbon base layer 7111 adsorbs residual odors and small harmful substances. The purified air is discharged from the bottom of the filter cartridge, while dust, impurities, etc., remain inside the filter cartridge and can be cleaned periodically. This effectively avoids dust pollution of the production environment and improves the purity of raw materials.
[0035] In use, the raw material is poured in through the feed pipe 614, which is stably fixed to the side plate 2 by a fixing bracket. The motor 616 starts, driving the short shaft 617 to rotate. The gear 618 on the short shaft rotates accordingly. Since the gear 618 meshes with the gear 615 on the outer wall of the connecting cylinder 613, the connecting cylinder 613 rotates, which in turn drives the connected inner screening cylinder 612 to rotate. The rotation of the inner screening cylinder causes the raw material to tumble and move inside the cylinder, ensuring that the raw material can fully contact the cylinder wall, preparing for subsequent screening. As the inner screening cylinder 612 rotates, the screening holes of different diameters on its outer wall come into play. The motor 6111 operates synchronously, driving the long... When shaft 6112 rotates, the spiral blades 6113 on the long shaft rotate inside the screening cylinder, pushing the raw material towards the discharge end. During the movement, smaller particles of raw material pass through screening hole one, screening hole two, and screening hole three in sequence according to their particle size. The raw material with a particle size smaller than screening hole one passes through first and falls into the corresponding discharge funnel 619. The raw material with a particle size between screening hole one and screening hole two passes through screening hole two and falls into the corresponding discharge funnel. This process is repeated to achieve precise grading and screening of raw materials according to particle size. Qualified raw materials of different specifications enter the corresponding collection box 5 from different discharge funnels and can be directly transported to the subsequent adaptation process.
[0036] During the screening process, the suction pump 717 is activated, generating suction. Dust-laden air enters the filter cartridge 715 from the dust hood through the suction pipe 712, the connecting horizontal pipe 713, and the connecting vertical pipe 714. Inside the filter cartridge, the air first passes through the filter layer 718, which initially filters out larger dust particles. Then, the fine filter layer 719 further intercepts fine dust. Finally, the activated carbon base layer 7111 adsorbs residual odors and small harmful substances. The purified air is discharged from the bottom of the filter cartridge, while dust, impurities, etc., remain inside the filter cartridge and can be cleaned periodically. This effectively avoids dust pollution of the production environment and improves the purity of raw materials.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
