Description

Technical Field

[0001] This utility model relates to the field of toothed rollers, and specifically to a toothed roller with a high-efficiency cooling system. Background Technology

[0002] Toothed rollers are high-efficiency industrial devices typically used for material crushing, calendering, or conveying under high-temperature or high-friction conditions. Their core feature is the integrated circulating cooling channel (such as a water-cooling or air-cooling system) within the roller. This fluid circulation removes heat generated during operation, effectively preventing overheating and deformation, material performance degradation, or lubrication failure. The cooling system provides precise temperature control, ensuring the toothed roller maintains stable mechanical strength and wear resistance during continuous operation, extending its service life. This makes them suitable for harsh production environments in metallurgy, mining, and building materials industries.

[0003] Chinese patent CN211964369U discloses a special toothed roller for granulation, comprising two roller bodies, namely a first toothed roller and a second toothed roller used in cooperation with each other. The first roller surface teeth of the first toothed roller are arranged parallel to the first drive shaft, and the second roller surface teeth of the second toothed roller are arranged perpendicular to the second drive shaft. The teeth on both the first and second toothed rollers are through teeth, and the roller surface material of both the first and second toothed rollers is gear-type wear-resistant material. This utility model achieves cross-cutting and crushing of materials by changing the arrangement and shape of the teeth on existing rollers, resulting in good particle morphology and improved yield. However, this device still has the following problems:

[0004] 1. During the crushing process, the toothed roller wears unevenly, with the teeth in the middle section typically wearing more wear than those on the sides. Once the teeth of this device wear out, the entire toothed roller needs to be replaced, which is costly.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A toothed roller with a high-efficiency cooling system includes a roller 1 and a rotating frame 5. The two ends of the roller 1 are rotatably connected between the tops of the two rotating frames 5. The roller 1 is equipped with multiple modular and convenient replacement mechanisms 2 for quick replacement of worn teeth on the toothed roller. The multiple modular and convenient replacement mechanisms 2 are arranged in a ring array. The roller 1 is equipped with a self-lubricating mechanism 3 for lubricating the rotation of the toothed roller. The roller 1 is equipped with a water-cooling mechanism 4 for cooling the toothed roller and the self-lubricating mechanism 3.

[0037] The modular and easy-to-change mechanism 2 includes a modular component 21 and a fixed component 22; the modular component 21 is connected to the roller 1, and both the roller 1 and the modular component 21 are connected to the fixed component 22; the modular component 21 is used to divide the teeth into areas of equal size; the fixed component 22 is used to fix the modular component 21.

[0038] In this invention, the roller 1 is lubricated by the self-lubricating mechanism 3 during rotation, while the water-cooling mechanism 4 cools the self-lubricating mechanism 3 and the roller 1 to prevent the roller body from overheating and deforming, the material properties from deteriorating, or the lubrication from failing during operation. When wear occurs on the modular component 21, the corresponding area of ​​the modular component 21 can be quickly removed and replaced by the fixing component 22 to avoid replacing the entire toothed roller.

[0039] In some embodiments, the modular component 21 includes a toothed plate 211 and a dovetail block 213. The outer side of the toothed plate 211 is fixedly connected to multiple sets of teeth arranged in a circumferential array, and multiple teeth in each set are equally spaced. Multiple dovetail grooves 212 are arranged in a circumferential array on the outer side wall of the roller 1. The inner side of the toothed plate 211 is fixedly connected to the outer side of the dovetail block 213, and the dovetail block 213 is slidably connected to the roller 1 through the dovetail grooves 212.

[0040] The fixing component 22 includes a fixing plate 221, screws 222 and fixing blocks 223; multiple fixing blocks 223 are fixedly arranged in a circumferential array at both the front and rear ends of the roller 1. The fixing blocks 223 have slots. One end of the fixing plate 221 is inserted into the slot and plugged in. The other end of the fixing plate 221 is sealed at the port of the dovetail groove. Both the fixing plate 221 and the roller 1 have screw holes. The screws 222 are threadedly connected to the fixing plate 221 and the roller 1 through the screw holes.

[0041] In this invention, when a tooth needs to be replaced due to wear, the side screw 222 of the dovetail groove 212 where the tooth 211 corresponding to the tooth to be replaced is located is unscrewed. Then, one end of the fixing plate 221 is slid out of the slot. At this time, the fixing plate 221 no longer blocks the dovetail clip 213 from sliding out. The tooth 211 to be replaced is removed and replaced with a new tooth 211 through the dovetail groove 212 and the dovetail clip 213. Then, one end of the fixing plate 221 is inserted into the slot to reset it. The screw 222 is tightened to fix the position of the fixing plate 221, thus completing the replacement of the tooth at the required position. This avoids replacing the tooth roller and reduces the overall cost.

[0042] In some embodiments, the self-lubricating mechanism 3 includes a bearing assembly 31 and a self-lubricating assembly 32; both the bearing assembly 31 and the self-lubricating assembly 32 are connected to the roller 1, and the bearing assembly 31 is connected to the self-lubricating assembly 32; the bearing assembly 31 is used to rotatably connect the roller 1 to the rotating frame 5; the self-lubricating assembly 32 is used to self-lubricate the rotating ring 312.

[0043] Specifically, the bearing assembly 31 includes a fixed ring 311, a rotating ring 312, and a rotor 313; the rotating frame 5 has a rotating hole, the fixed ring 311 is fixedly installed in the rotating hole of the rotating frame 5, and rotating shafts are fixedly installed on both the front and rear sides of the roller 1; the two rotating rings 312 are respectively fixedly connected to the rotating shafts on both sides of the roller 1, the rotating rings are rotatably arranged inside the fixed ring 311, and multiple rotors 313 are arranged in a circumferential array inside the fixed ring 311. The rotors 313 are rolledly connected to the fixed ring 311 and rotatably connected to the rotating ring 312; both the fixed ring 311 and the rotors 313 are connected to the self-lubricating assembly 32.

[0044] The self-lubricating component 32 includes a lubricating block 321, a flow channel 322, a lubricating oil filling chamber 323, and a transparent monitoring plate 324. The lubricating block 321 is fixedly connected to the bottom side of the inner side of the fixing ring 311, and the lubricating block 321 is tumblingly connected to the rotor 313. The lubricating block 321 is made of sponge material, and a flow channel 322 is provided on the inner side of the fixing ring 311. The front end of the flow channel 322 is connected to the inside of the lubricating oil filling chamber 323, and the lubricating oil filling chamber 323 is fixedly connected to the side of the fixing ring 311. The transparent monitoring plate 324 is fixedly installed on the side of the lubricating oil filling chamber 323 away from the fixing ring 311.

[0045] In this invention, the operator adds lubricating oil to the lubricating oil filling chamber 323. The lubricating oil flows into the flow channel 322 through the lubricating oil filling chamber 323 and comes into contact with the lubricating block 321. After the lubricating block 321 absorbs the lubricating oil, the rotor 313 rolls over the lubricating block 321 and is coated with lubricating oil, thus ensuring the lubrication effect. At the same time, excess lubricating oil flows back into the lubricating block 321 through the flow channel 322. The state of the lubricating oil in the lubricating oil filling chamber 323 and the flow channel 322 can be observed from the outside through the transparent monitoring plate 324.

[0046] In some embodiments, the water cooling mechanism 4 includes a water inlet / outlet assembly 41 and a water cooling assembly 42; both the water inlet / outlet assembly 41 and the water cooling assembly 42 are connected to the roller 1. The water inlet / outlet assembly 41 is connected to the water cooling assembly 42. The water inlet / outlet assembly 41 is used for water inlet and water outlet of the water cooling assembly 42. The water cooling assembly 42 is used to cool the roller 1, the rotating ring 312 and the fixed ring 311.

[0047] The water inlet / outlet assembly 41 includes a water-passing slip ring 411; two water-passing slip rings 411 are sleeved on the front and rear ends of the roller 1 and are symmetrically arranged. The rotor of the water-passing slip ring 411 is fixedly connected to the rotating shaft at the front and rear ends of the roller 1. The stators of the two water-passing slip rings 411 are fixedly connected to the water inlet pipe and the water outlet pipe, respectively. The water-passing slip ring 411 is connected to the water cooling assembly 42.

[0048] The water-cooling assembly 42 includes a water-cooling pipe 421; multiple water-cooling pipes 421 are arranged in a circumferential array inside the roller 1; the water-cooling pipes 421 are fixedly connected to the inner wall of the roller 1; and the two ends of the water-cooling pipes 421 are fixedly connected to the rotors of two water-passing slip rings 411 respectively.

[0049] In this invention, the water inlet pipe delivers cold water to the inside of the water cooling pipe 421 through the water slip ring 411 at one end, and then delivers it to the water outlet pipe through the water cooling pipe 421 and the water slip ring 411 at the other end to cool the roller 1. At the same time, the cooling water passing through the water slip ring 411 simultaneously cools the rotating shaft of the roller 1, so as to avoid the rotating shaft temperature from being too high and causing lubrication failure and wear.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
