Description

Technical Field

[0001] This utility model relates to the field of open mill technology, and in particular to a material scraping device for an open mill for low dielectric loss PVC cable material. Background Technology

[0002] In the industrial production of low dielectric loss PVC cable materials, in order to avoid the formation of "local impurity spots" when old material is not cleaned off the rollers and mixed with new material, which would lead to an increase in the dielectric loss of the cable insulation layer, a material scraping device is used to scrape off and clean the material adhering to the roller surface.

[0003] Existing scraping devices are typically fixed to both sides of the open mill rollers via brackets, with one set for the front roller and one for the rear roller. The distance between the scraping component and the roller surface is adjusted according to the roller diameter, usually leaving a margin of 0.1-0.2mm to ensure close contact without hard friction. When the open mill completes the mixing of a batch of materials, the operator uses the control panel to direct the scraping component to adhere to the roller surface at a set angle and pressure under the drive of a cylinder or motor, thereby scraping off the material from the roller surface.

[0004] Considering that the existing collection components are mostly fixed and can only collect from the processing area of ​​the roller, it is difficult to accurately collect from the scraping area when scraping, which makes it easy for the scraped cable material to scatter outside the equipment, resulting in material waste, equipment pollution, and increased difficulty in subsequent cleaning. Therefore, a material scraping device for a low dielectric loss PVC cable material open mill is proposed to solve the above problems. Utility Model Content

[0020] Reference Figures 1-3 A scraping assembly 3 is provided on the left side of the inner surface of the machine body 1. The scraping assembly 3 is used to scrape off the cable material attached to the open milling roller 2, thereby realizing the scraping function. The scraping assembly 3 includes a motor A302, which provides power for the rotation of the threaded rod 303 and is the power source for the entire scraping action. The outer surface of the motor A302 is fixedly connected to the left side of the inner surface of the machine body 1. The threaded rod 303 serves as a transmission component, converting the rotational motion of the motor A302 into the linear motion of the threaded component 304, thereby driving the scraper 301 to move. The output end of the motor A302 is fixedly connected to the threaded rod 303. The outer surface of the threaded rod 303 is threaded through and connected to the threaded component 304. The threaded component 304 is used to transmit the power of the threaded rod 303, driving the scraper 301 to approach or move away from the milling roller 2. The outer surface of the threaded rod 303 is fixedly connected to the scraper 301, which is used to contact the surface of the open milling roller 2 and scrape off the cable material attached to the open milling roller 2, thereby realizing the scraping function.

[0021] Reference Figure 3The outer surface of the threaded rod 303 is rotatably connected to the left side of the inner surface of the machine body 1, ensuring that the threaded rod 303 can rotate stably and providing a basis for thread transmission. The outer surface of the threaded component 304 is slidably connected to the left side of the inner surface of the machine body 1, restricting the movement of the threaded component 304 to linear motion, ensuring that the threaded component 304 can move in a straight line when the threaded rod 303 rotates, thereby driving the scraper 301 to move accurately. The outer surface of the scraper 301 is slidably connected to the inner surface of the machine body 1, so that the scraper 301 remains stable during movement, ensuring that the scraper 301 can make good contact with the surface of the open roller 2, and improving the stability and accuracy of scraping.

[0022] Reference Figures 1-2 The inner left side of the machine body 1 is rotatably connected to the smelting roller 2. The smelting roller 2 is the core component for smelting cable material. By rotating, the cable material is melted and mixed on its surface. The outer right side of the machine body 1 is fixedly connected to the motor B9. The motor B9 provides power for the rotation of the smelting roller 2, driving the smelting roller 2 to perform the smelting operation of the cable material. The output end of the motor B9 is fixedly connected to the outer right side of the smelting roller 2, transmitting the power of the motor B9 to the smelting roller 2, so that the smelting roller 2 obtains the power to rotate, thereby realizing the smelting of the cable material.

[0023] Reference Figures 1-2 , Figure 5 The outer surface of the scraper 301 is in contact with the outer surface of the sifting roller 2, which is the key contact part for realizing the scraping function. By contacting the surface of the sifting roller 2, the attached cable material is scraped off. There are two sets of sifting rollers 2, which are symmetrically distributed at the front and rear of the machine body 1, so as to facilitate the full sifting of the cable material and make the cable material melt and mix better between the two sets of sifting rollers 2, thereby improving the sifting effect. The front of the inner surface of the pull plate 6 is elastically connected to the handle 8 by the spring 11. The spring 11 makes the handle 8 elastically extendable and retractable. When not in use, it can be retracted into the pull plate 6 to save space. When in use, it can be popped out for gripping and pulling the pull plate. The outer surface of the handle 8 is slidably connected to the front end of the inner surface of the pull plate 6, which facilitates the extension and retraction of the handle 8 in the pull plate 6 and makes it easy to operate the pull plate 6 to be pulled out and pushed in.

[0024] Reference Figures 4-6One end of the spring 11 is fixedly connected to the front of the inner surface of the pull plate 6, and the other end of the spring 11 is fixedly connected to the rear of the outer surface of the handle 8. The spring 11 provides elastic support for the handle 8, enabling the handle 8 to automatically reset under the action of the spring 11, ensuring the convenience of using the handle 8. Two sets of guide grooves 10 and guide blocks 12 are provided, symmetrically distributed at the bottom of the pull plate 6, further enhancing the stability and guidance of the pull plate 6 during sliding, making the movement of the pull plate 6 more smooth and reliable. The cross-sections of both the guide grooves 10 and the guide blocks 12 are T-shaped. It can effectively prevent the pull plate 6 from detaching from the machine body 1 during the sliding process, and improve the stability of the connection. The outer surface of the scraper 301 is fixedly connected with a baffle 4. The baffle 4 is used to block the scraped material and prevent the material from falling from both sides of the scraper 301, ensuring that the material can fall accurately into the tray 5 below, and improving the integrity of material collection. There are two sets of baffles 4, which are symmetrically distributed on the left and right sides of the outer surface of the scraper 301, blocking the material from both sides, further ensuring that the material will not fall from the side of the scraper 301, and improving the material collection effect.

[0025] Working principle: When the cable material is being processed, motor B9 is first started, and through the synchronous regulator, it simultaneously drives two sets of processing rollers 2 to rotate inward. After the processing rollers 2 are heated to the specified temperature, the cable material is poured between the two processing rollers 2, allowing it to melt and adhere to one set of processing rollers 2. During processing, a special tool is used to manually move the cable material adhering to the processing rollers 2 to prevent it from shifting off the surface. When the base material is melted, specific additives are added to fuse with it. After processing is complete, the handle 8 is moved outward to extend... Pull the pull plate 6 outwards so that it can be gripped. Then, while holding the handle 8, pull it outwards to move the pull plate 6 outwards. This allows the center of the tray 5 at the top of the pull plate 6 to be aligned with the bottom of the scouring roller 2 located at the front of the machine body 1. Then, start the motor A302. When it drives the threaded rod 303 to rotate, the threaded connection between the threaded rod 303 and the threaded part 304 causes the scraper 301 fixed on the threaded part 304 to move closer to the surface of the scouring roller 2. The scraper 301 scrapes the cable material attached to the surface of the scouring roller 2 into the bottom tray 5, thereby completing the scouring and collection of the cable material.
