DETAILED DESCRIPTION
[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0018] The high-speed mixing device in the prior art generally uses a motor to drive the stirring blades to rotate at high speed in the stirring barrel to achieve the mixing effect of the materials. However, during the stirring process, the PVS resin particles will collide with each other and rub against each other under the drive of the stirring blades, and then quickly heat up and are prone to softening. In addition, during the stirring process, the materials will continuously collide with the inner wall of the stirring barrel under the action of centrifugal force, causing a large amount of material to stick to the side walls of the stirring barrel, which will affect the mixing effect of the materials.
[0019] In order to solve the above technical problems, the present application provides a high-speed mixing device for producing optical cable sheath materials.
[0020] See also Figure 2 A high-speed mixing device for producing optical cable sheath materials comprises: a stirring barrel 1, a stirring device 2, and a cleaning device 3; a cavity for containing materials is provided inside the stirring barrel 1; the stirring device 2 is rotatably arranged in the cavity for stirring materials; the cleaning device 3 comprises: a driving frame 31 and a scraper assembly 32; the driving frame 31 is rotatably arranged in the cavity; the driving frame 31 is connected to the scraper assembly 32 through a fixing rod 311; the scraper assembly 32 is in contact with the side wall of the stirring barrel 1.
[0021] In the specific implementation process, the stirring device 2 stirs the materials in the stirring barrel 1 to achieve the effect of mixing the various materials in the stirring barrel 1; since the raw material of the sheath is PVS resin, during the mixing process, the materials will rub and collide with each other and then quickly heat up, which is easy to cause the PVS resin particles to soften, and will stick to the side wall of the stirring barrel 1 under the action of centrifugal force. The driving frame 31 in the cleaning device 3 drives the scraper assembly 32 to rotate along the inner wall of the stirring barrel 1 through the fixed rod 311, which can effectively scrape off the materials stuck on the inner wall of the stirring barrel 1. After being scraped off, the materials will fall back into the stirring barrel 1 and continue to be stirred, so that the various materials in the stirring barrel 1 can be fully mixed, ensuring the mixing effect of the materials; and after the stirring is completed, it effectively avoids the problem that a large amount of materials will stick to the inner wall of the stirring barrel 1 and are difficult to discharge, thereby reducing the loss of materials and saving production costs.
[0022] It should be noted that a feed pipe 11 is provided at the top of the mixing barrel 1 to allow materials to be fed into the mixing barrel 1 ; a discharge pipe 12 is provided at the bottom of the mixing barrel 1 to allow materials to be discharged after mixing is completed.
[0023] See also Figure 2In the specific implementation process, the stirring device 2 includes: a stirring shaft 21 and a high-speed motor 22; the stirring shaft 21 is rotatably arranged in the cavity, and the stirring shaft 21 is provided with a plurality of stirring blades 211; the plurality of stirring blades 211 are arranged along the circumference of the stirring shaft 21; the high-speed motor 22 is arranged outside the stirring barrel 1, and the output shaft of the high-speed motor 22 penetrates the inner wall of the stirring barrel 1 and is transmission-connected with the stirring shaft 21. The high-speed motor 22 drives the plurality of stirring blades 211 to rotate at a high speed in the stirring barrel 1 through the stirring shaft 21, which can quickly stir the materials, so that all kinds of materials can be fully mixed in a short time. The high-speed motor 22 is arranged outside the stirring barrel 1, on the one hand, to avoid occupying the space of the cavity, so that the stirring barrel 1 can be put into more materials, and on the other hand, to prevent the materials from entering the high-speed motor 22 during operation, which may cause the high-speed motor 22 to burn out. In addition, after the high-speed motor 22 is connected to the stirring shaft 21, in order to avoid deviation of the axes of the two, which may cause severe shaking during high-speed operation, a universal head 221 is also provided on the output shaft of the high-speed motor 22 to be connected to the stirring shaft 21 for transmission. The universal head 221 can effectively prevent the stirring shaft 21 from shaking when rotating at high speed, thereby ensuring the stability of the device during operation.
[0024] It should be noted that since the stirring shaft 21 and the driving frame 31 are both arranged in the cavity, in order to avoid interference with each other during operation, in the specific implementation process, the stirring shaft 21 and the driving frame 31 are arranged relative to each other in the cavity. At the same time, since the materials will accumulate at the bottom of the mixing barrel 1 under the influence of gravity, in order to enable the stirring shaft 21 to stir more materials, it is more reasonable to arrange the stirring shaft 21 at the bottom of the mixing barrel 1, which can further improve the mixing efficiency; and the driving frame 31 is arranged at the top of the mixing barrel 1 to avoid interference with the stirring shaft 21 during operation.
[0025] See also Figure 2In the specific implementation process, the cleaning device 3 also includes: a low-speed motor 33, which is arranged outside the mixing barrel 1; the low-speed motor 33 penetrates the inner wall of the mixing barrel 1 and is in transmission connection with the driving frame 31. The low-speed motor 33 drives the scraper assembly 32 to rotate at a low speed along the inner wall of the mixing barrel 1 through the fixed rod 311 on the driving frame 31, so as to avoid severe friction between the scraper assembly 32 and the inner wall of the mixing barrel 1, so as to reduce the wear of the scraper assembly 32 and improve the service life of the scraper assembly 32. In addition, a support ring 13 is also provided in the mixing barrel 1, and the support ring 13 is rotatably connected to the inner wall of the mixing barrel 1; one end of the scraper assembly 32 is connected to the fixed rod 311, and the other end is connected to the support ring 13. During the operation of the scraper assembly 32, the fixed rod 311 and the support ring 13 support the scraper assembly 32 from both ends of the scraper assembly 32, so that the scraper assembly 32 can fully fit the inner wall of the mixing barrel 1, ensuring the scraper assembly 32 to scrape the material adhering to the inner wall of the mixing barrel 1. In order to prevent the support ring 13 from shifting during operation, an annular groove is provided on the inner wall of the mixing barrel 1, and the support ring 13 is rotatably installed in the annular groove, which can prevent the support ring 13 from shifting during rotation.
[0026] It should be noted that there is no requirement for the number of scraper assemblies 32, which can be one, two, three or more. The more the number, the higher the efficiency of scraping the material adhering to the inner wall of the mixing barrel 1, but it will not have a significant impact on the mixing effect of the material. At the same time, the more the number, the more complex the structure and the higher the production cost. In the specific implementation process, the number of scraper assemblies 32 is four; they are evenly distributed along the circumference of the mixing barrel 1, so that the design can evenly scrape the material.
[0027] See also Figure 2 and Figure 3In the specific implementation process, the scraper assembly 32 includes: a fixed plate 321 and a scraper strip 322; one end of the fixed plate is connected to the fixed rod 311, and the other end is connected to the support ring 13; the scraper strip 322 fits the side wall of the mixing barrel 1. The fixed rod 311 drives the fixed plate 321 to rotate, and supports the fixed plate 321 from both ends of the fixed plate 321 with the support ring 13, so that the scraper strip 322 can fully fit the side wall of the mixing barrel 1 to scrape and clean the material. In addition, the scraper strip 322 is made of rubber material. On the one hand, the rubber material is soft and easy to deform, so it can better fit the side wall of the mixing barrel 1; on the other hand, the hardness of the rubber material is low, and the mixing barrel 1 will not be scratched during operation. In addition, both ends of the scraper strip 322 are provided with a fastening mechanism 4; the fastening mechanism 4 is used to fix the scraper strip 322 to the fixed plate 321. Since the scraper bar 322 will constantly rub against the inner wall of the mixing barrel 1 during operation, the scraper bar 322 will be worn, causing the scraping and cleaning effect of the scraper bar 322 on the material to gradually decrease. Therefore, the fastening mechanism 4 can achieve the effect of detachable connection between the scraper bar 322 and the fixed plate 321, so that a new scraper bar 322 can be replaced on the fixed plate 321.
[0028] See also Figure 4 In the specific implementation process, the fastening mechanism 4 includes: a connecting rod 41, a nut 42, and a spring 43; one end of the connecting rod 41 is fixedly connected to the scraper strip 322, and the other end passes through the fixed plate 321; the nut 42 is connected to the connecting rod 41 by threaded fit. After the nut 42 on the connecting rod 41 is screwed out, the scraper strip 322 can be pulled out from the fixed plate 321 through the connecting rod 41, and then a new scraper strip 322 can be replaced, which is simple to operate and easy to maintain. In addition, the fastening mechanism 4 also includes: a spring 43; the spring 43 is sleeved on the connecting rod 41; the spring 43 is arranged between the fixed plate 321 and the scraper strip 322. By installing a spring 43 between the fixed plate 321 and the scraper bar 322, an elastic connection is formed between the two. On the one hand, the fitting effect of the scraper bar 322 can be improved, so that the scraper bar 322 can fit more closely to the side wall of the mixing barrel 1; on the other hand, driven by the spring 43, the worn scraper bar 322 will still fit closely to the side wall of the mixing barrel 1, extending the service life of the scraper bar 322, making the scraper bar 322 more durable and reducing the maintenance cost.
[0029] See also Figure 2 and Figure 3In the specific implementation process, the scraper assembly 32 further includes: a spoiler 323; the spoiler 323 is connected to the fixed plate 321. Since the stirring shaft 21 is driven by the high-speed motor 22, the material in the stirring barrel 1 will splash around at high speed under the driving of the stirring shaft 21, and the driving frame 31 is driven by the low-speed motor 33, so the spoiler 323 runs at a low speed, and the material in the stirring barrel 1 will continuously hit the spoiler to achieve the effect of breaking up the material, so that the material can be mixed more fully and the mixing effect of the material is improved.
[0030] It should be noted that when the material hits the spoiler 323, the material stuck on the spoiler 323 will be affected by the centrifugal force and thrown out of the spoiler 323, so during the operation, the material will not stick to the spoiler 323. In addition, the driving frame 31 and the stirring shaft 21 rotate in opposite directions. This design can speed up the relative speed between the material and the spoiler 323, so that the material can hit the spoiler 323 more violently, further improving the mixing effect of the material.
[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
