Description

Technical Field

[0001] The present invention relates to the technical field of glass fiber production, and particularly to a multi-stage raw material crushing device applied to glass fiber production. Background Art

[0002] Glass fiber is an excellent inorganic non-metallic material with a wide variety of types. Its advantages are good insulation, high heat resistance, good corrosion resistance, and high mechanical strength. However, its disadvantages are brittleness and poor wear resistance. Many high-quality kaolin raw ore powders can be directly used in the glass fiber industry after grinding. In the process of glass fiber production, nano-level kaolin is required. When producing nano-level kaolin, the raw materials need to be purified and impurity-removed.

[0003] Publication No. CN117380332B discloses a kaolin crushing device for glass fiber production. Two crushing rollers crush the raw materials, and the crushed raw materials are collected by a collection cavity below the two crushing rollers. The filter holes on the rotating cylinder filter the raw materials. The raw materials with qualified particle sizes fall from the filter holes and are discharged from the discharge port of the processing box. The raw materials with unqualified particle sizes continue to be collected by the collection cavity below the crushing rollers until they are dropped from above the two crushing rollers again, so that the raw materials with unqualified particle sizes are continuously crushed until they are qualified, thereby improving the crushing effect of the raw materials, improving the utilization rate of the raw materials, and thus saving raw materials. As the rotating cylinder rotates, the crushed raw materials in the collection cavity are in a flowing state, thereby improving the filtering effect. However, the following problems still exist in the actual use of this patent: Although the kaolin crushing device for glass fiber production can use the crushing rollers to crush the raw materials, the crushed raw materials are collected by a collection cavity below the two crushing rollers, and the filter holes on the rotating cylinder filter the raw materials. The raw materials with qualified particle sizes fall from the filter holes and are discharged from the discharge port of the processing box. However, since the distance between the crushing rollers is fixed, the particle size of the crushed kaolin is certain. When the hardness and particle size of the kaolin change, it is easy to cause damage to the crushing rollers when using fixed crushing rollers to crush the kaolin. At the same time, hard kaolin will get stuck between the crushing rollers, thereby affecting the crushing effect of the crushing rollers.

[0004] Therefore, a multi-stage raw material crushing device applied to glass fiber production is proposed to solve the problems mentioned above. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For a multi-stage crushing device for raw materials used in fiberglass production, since the diameters of the first crushing roller and the second crushing roller are different, the crushed particle sizes are also different.

Moving the conveying pipe into the interior of the crushing box can achieve uniform feeding on the tops of the first crushing roller and the second crushing roller, thereby improving the crushing efficiency of the kaolin raw materials. The specific content is as follows: 1. By setting up a multi-stage crushing mechanism, not only can the crushing motor drive the crushing driving gear to rotate, but also, taking advantage of the meshing connection among the crushing driving gear, the crushing driven gear, and the meshing tooth ring, the self-rotation of the crushing driven gear can be realized.

Through the relative rotation of the first crushing roller and the second crushing roller, the crushing of the kaolin raw materials can be achieved. When the first locking rack is engaged with the engaging ring, the second locking rack is separated from the meshing tooth ring, and the fixation of the first rotating disk and the crushing driven gear can be realized. At the same time, the meshing tooth ring drives the first connecting rotating ring, the filter screen cylinder, and the second connecting rotating ring to rotate, which can tumble and stir the kaolin raw materials that have not passed through the filter screen cylinder. At the same time, by means of the support plate and the arc-shaped plate, part of the kaolin raw materials can be driven to fall back between the first crushing roller and the second crushing roller for repeated crushing, improving the crushing effect of the kaolin. By pressing the locking ring and taking advantage of the meshing connection between the locking gear and the first locking rack and the second locking rack, the relative movement of the first locking rack and the second locking rack can be realized. When the second locking rack is engaged with the meshing tooth ring, the fixation of the filter screen cylinder can be realized. At the same time, the first locking rack is separated from the engaging ring, and the revolution of the first rotating disk and the crushing driven gear can be realized, thereby adjusting the position between the first crushing roller and the second crushing roller. Since the diameters of the first crushing roller and the second crushing roller are different, the crushed particle sizes are also different. By gradually crushing large-particle-size kaolin raw materials, the crushing effect of the kaolin raw materials is improved. Utilizing the elastic force of the protective spring inside the protective chute, the sliding of the crushed blocks can be achieved, thereby protecting the crushed blocks and increasing the service life of the crushed blocks. The outer surface of the filter screen cylinder can be cleaned by the cleaning brush, thereby improving the filtering effect of the filter screen cylinder. By driving the blocking block to rotate with the rotating handle, the second rotating disk can be opened, and the crushed raw materials can be conveyed to the tops of the first crushing roller and the second crushing roller, facilitating the crushing of the raw materials; 2. By setting up the conveying and feeding mechanism, not only can the conveying motor drive the conveying rotating rod to rotate, so that the conveying rotating rod drives the conveying spiral blade to rotate, and through the structural characteristics of the conveying spiral blade, the conveying of raw materials can be realized. At the same time, the first roller at the bottom of the first support leg can be used to move the entire conveying pipe, move the conveying pipe into the interior of the crushing box, and can realize the uniform feeding on the tops of the first crushing roller and the second crushing roller, thereby improving the crushing efficiency of kaolin raw materials.

By driving the crushing driving gear 103 to rotate by the crushing motor 102, and using the meshing connection characteristics among the crushing driving gear 103, the crushing driven gear 104 and the meshing tooth ring 105, the self-rotation of the crushing driven gear 104 can be realized. The first rotating connecting shaft 111 and the first crushing roller 113 are driven to rotate by the crushing driving gear 103, and at the same time, the second rotating connecting shaft 112 and the second crushing roller 114 are driven to rotate by the crushing driven gear 104. By the relative rotation of the first crushing roller 113 and the second crushing roller 114, the crushing of kaolin raw materials can be realized.

[0020] A number of protective sliding grooves 115 are provided inside both the first crushing roller 113 and the second crushing roller 114. A number of protective springs 116 are fixedly installed inside the protective sliding grooves 115. Crushing blocks 117 are fixedly installed on the outer sides of the protective springs 116. The diameters of the first crushing roller 113 and the second crushing roller 114 are different. One end of the inside of the crushing box 101 away from the crushing motor 102 is rotatably connected with a second connecting rotating ring 118. A second rotating disc 119 is rotatably connected inside the second connecting rotating ring 118. A number of plugging blocks 120 are threadedly connected inside the second rotating disc 119.

A first locking rack 131 and a second locking rack 132 are meshingly connected to the top and bottom of the locking gear 130 respectively. Support sliders 133 are symmetrically installed inside the locking brackets 129. When the first locking rack 131 is in snap-fit connection with the engaging ring 107, the second locking rack 132 is separated from the meshing gear ring 105, and the fixation of the first rotating disc 108 and the crushing driven gear 104 can be realized. At the same time, the meshing gear ring 105 drives the first connecting rotating ring 106, the filter screen cylinder 123 and the second connecting rotating ring 118 to rotate, and the kaolin raw materials that have not passed through the filter screen cylinder 123 can be tumbled and stirred. At the same time, the support plates 127 and the arc-shaped plates 128 can drive some kaolin raw materials to fall back between the first crushing roller 113 and the second crushing roller 114 for repeated crushing, improving the effect of kaolin crushing. By pressing the locking ring 134, using the characteristic of the meshing connection between the locking gear 130 and the first locking rack 131 and the second locking rack 132, the relative movement of the first locking rack 131 and the second locking rack 132 can be realized. When the second locking rack 132 is in snap-fit connection with the meshing gear ring 105, the fixation of the filter screen cylinder 123 can be realized. At the same time, the first locking rack 131 is separated from the engaging ring 107, and the revolution of the first rotating disc 108 and the crushing driven gear 104 can be realized, so as to adjust the position between the first crushing roller 113 and the second crushing roller 114.Since the diameters of the first crushing roller 113 and the second crushing roller 114 are different, the particle sizes of the crushed materials are different. By gradually crushing the kaolin raw materials with large particle sizes, the crushing effect of the kaolin raw materials can be improved.

[0021] The supporting slider 133 is respectively slidably connected with the first locking rack 131 and the second locking rack 132. A locking ring 134 is fixedly installed on the outer side of the second locking rack 132. The first locking rack 131 is engaged with the engaging ring 107, and the first locking rack 131 is engaged with the meshing tooth ring 105.

A vacuum cleaner 137 is fixedly installed at the top of the crushing box 101. Stable brackets 138 are symmetrically installed on both sides of the bottom of the crushing box 101. By utilizing the elastic force of the protective spring 116 inside the protective chute 115, the sliding of the crushed block 117 can be realized, thereby protecting the crushed block 117 and improving the service life of the crushed block 117. The outer surface of the filter screen cylinder 123 can be cleaned by the cleaning brush 125, thereby improving the filtering effect of the filter screen cylinder 123. By driving the blocking block 120 to rotate by the rotating handle 121, the second rotating disk 119 can be opened, and the crushed raw materials can be conveyed to the tops of the first crushing roller 113 and the second crushing roller 114, facilitating the crushing of the raw materials.

[0022] The conveying and feeding mechanism 2 includes a conveying pipe 201. On one side inside the conveying pipe 201, a first bracket 202 is fixedly installed. At one end of the conveying pipe 201 away from the first bracket 202, a conveying motor 203 is fixedly installed. The output end of the conveying motor 203 is fixedly connected to a conveying rotating rod 204. On the outer side of the conveying rotating rod 204, a conveying spiral blade 205 is fixedly installed. On one side at the top of the conveying pipe 201, a feed pipe 206 is fixedly installed. At the top of the feed pipe 206, a feed hopper 207 is fixedly installed. At one end of the conveying pipe 201, a fixed support ring 208 is fixedly installed. On the bottom of the conveying pipe 201, first support legs 209 are symmetrically installed. At the bottom of the first support legs 209, first rollers 210 are fixedly installed. A support sliding ring 211 is slidably connected to the conveying pipe 201. At the bottom of the support sliding ring 211, second support legs 212 are fixedly installed. At the bottom of the second support legs 212, second rollers 213 are fixedly installed. By driving the conveying rotating rod 204 to rotate with the conveying motor 203, the conveying rotating rod 204 drives the conveying spiral blade 205 to rotate. Due to the structural characteristics of the conveying spiral blade 205, the conveying of raw materials can be achieved. At the same time, the movement of the entire conveying pipe 201 can be realized by using the first rollers 210 at the bottom of the first support legs 209. Moving the conveying pipe 201 into the interior of the crushing box 101 can achieve uniform feeding on the tops of the first crushing roller 113 and the second crushing roller 114, thereby improving the crushing efficiency of kaolin raw materials. By using the characteristic that the support sliding ring 211 is slidably connected to the conveying pipe 201, the movement of the support sliding ring 211 can be realized, which is convenient for inserting the conveying pipe 201 into the interior of the crushing box 101 for raw material feeding.

[0023] Working principle: Before using this multi-stage crushing device for raw materials applied to glass fiber production, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 11 As shown, first, drive the conveying rotating rod 204 to rotate with the conveying motor 203, so that the conveying rotating rod 204 drives the conveying spiral blade 205 to rotate. Due to the structural characteristics of the conveying spiral blade 205, the conveying of raw materials can be achieved. At the same time, the movement of the entire conveying pipe 201 can be realized by using the first rollers 210 at the bottom of the first support legs 209. Moving the conveying pipe 201 into the interior of the crushing box 101 can achieve uniform feeding on the tops of the first crushing roller 113 and the second crushing roller 114, thereby improving the crushing efficiency of kaolin raw materials. By using the characteristic that the support sliding ring 211 is slidably connected to the conveying pipe 201, the movement of the support sliding ring 211 can be realized, which is convenient for inserting the conveying pipe 201 into the interior of the crushing box 101 for raw material feeding.

[0024] Secondly, the crushing motor 102 is used to drive the crushing driving gear 103 to rotate. By virtue of the meshing connection among the crushing driving gear 103, the crushing driven gear 104 and the meshing tooth ring 105, the self-rotation of the crushing driven gear 104 can be realized. The first rotating connection shaft 111 and the first crushing roller 113 are driven to rotate by the crushing driving gear 103. At the same time, the second rotating connection shaft 112 and the second crushing roller 114 are driven to rotate by the crushing driven gear 104. The kaolin raw material can be crushed by the relative rotation of the first crushing roller 113 and the second crushing roller 114. When the first locking rack 131 is engaged with the engaging ring 107, the second locking rack 132 is separated from the meshing tooth ring 105, so that the first rotating disk 108 and the crushing driven gear 104 can be fixed. At the same time, the meshing tooth ring 105 drives the first connecting rotating ring 106, the filter screen cylinder 123 and the second connecting rotating ring 118 to rotate, so as to tumble and stir the kaolin raw material that has not passed through the filter screen cylinder 123. At the same time, the supporting plate 127 and the arc plate 128 can drive some kaolin raw materials to fall back between the first crushing roller 113 and the second crushing roller 114 for repeated crushing, improving the crushing effect of kaolin.

[0025] Finally, by pressing the locking ring 134, due to the meshing connection among the locking gear 130, the first locking rack 131 and the second locking rack 132, the relative movement of the first locking rack 131 and the second locking rack 132 can be realized. When the second locking rack 132 is engaged with the meshing tooth ring 105, the filter screen cylinder 123 can be fixed. At the same time, the first locking rack 131 is separated from the engaging ring 107, and the revolution of the first rotating disk 108 and the crushing driven gear 104 can be realized, thereby adjusting the position between the first crushing roller 113 and the second crushing roller 114. Since the diameters of the first crushing roller 113 and the second crushing roller 114 are different, the particle sizes of the crushed materials are different. By gradually crushing the kaolin raw materials with large particle sizes, the crushing effect of the kaolin raw materials can be improved. By virtue of the elastic force of the protective spring 116 inside the protective chute 115, the sliding of the crushing block 117 can be realized, thereby protecting the crushing block 117 and improving the service life of the crushing block 117. The outer surface of the filter screen cylinder 123 can be cleaned by the cleaning brush 125, thereby improving the filtering effect of the filter screen cylinder 123. By driving the blocking block 120 to rotate with the rotating handle 121, the second rotating disk 119 can be opened, and the crushed raw materials can be conveyed to the tops of the first crushing roller 113 and the second crushing roller 114, facilitating the crushing of the raw materials.

[0026] Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
