Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a high-load, low-resistance electric cone roller. Background Technology

[0002] During material conveying, the conveyor rollers come into contact with the conveyed items or conveyor belts. Driven by a motor, the conveyor rollers rotate and the materials are conveyed through friction. When conveying materials through curves, tapered rollers are usually used. The tapered design of the tapered rollers results in different linear velocities at different positions, which can ensure that the materials transition smoothly at curves. In the use of existing tapered rollers, the bearings on both sides are usually installed in a suitable position through bearing seats, and then the roller of the tapered roller is installed between the two bearings through a roller shaft. During operation, the roller shaft is driven by a motor to rotate, causing the roller to rotate and directly transport items through friction or indirectly transport items through a conveyor belt. The following problems exist: When installing the tapered roller, it is necessary to reserve space for the installation stroke of the tapered roller shaft in advance. The installation of the tapered roller occupies a lot of space and has low installation efficiency, which is not convenient for dense installation. Therefore, we propose a high load-bearing, low-resistance electric tapered roller. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high load-bearing, low-resistance electric conical roller. By setting the adjustment mechanism, the roller shaft can be retracted into the inside of the roller cylinder. After the shaft is retracted, the overall length of the conical roller is shortened, and there is no need to reserve the installation stroke space of the roller shaft. This allows the conical roller to quickly align with the bearing seat, which can be adapted to narrow spaces and dense installations, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-load, low-resistance electric conical roller, including a roller cylinder, adjustable roller shafts on both the left and right sides inside the roller cylinder, and an adjustment mechanism; Adjustment mechanism: It includes a chamber, rib groove, rib, threaded groove, adjustment block, drive assembly, and fixing assembly. The roller has chambers on both the left and right sides. The inner wall of the chamber has evenly distributed rib grooves on the side near the center of the roller. The roller shaft is slidably connected to the inside of the chamber. The outer surface of the roller shaft has ribs on the side near the center of the roller. The ribs are slidably connected to the inside of the rib grooves on the same side. The outer surface of the roller shaft has threaded grooves. The outer surface of the threaded grooves is threadedly connected to the adjustment block through the drive assembly. The roller has fixing assembly on both the left and right sides. The adjustment mechanism allows the roller shaft to retract into the inside of the roller. After the shaft is retracted, the overall length of the tapered roller is shortened, eliminating the need to reserve installation stroke space for the roller shaft. This allows the tapered roller to quickly align with the bearing seat and is suitable for narrow spaces and dense installations.

[0005] Furthermore, the roller is shaped like a frustum with a larger diameter on the left than on the right, and the depth of the cavity at the large end of the roller is greater than the depth of the cavity at the small end of the roller. This ensures that the shaft is subjected to uniform force during extension and retraction, without affecting the load-bearing and guiding performance of the tapered roller.

[0006] Furthermore, the drive assembly includes a rotating seat, a clearance groove, and a sealed bearing. The side of the adjusting block away from the center of the roller is provided with a rotating seat, the outer surface of the rotating seat is provided with a clearance groove, and the interior of the clearance groove is provided with a sealed bearing. The rotating seats are rotatably connected to the interior of the chamber on the same side through the sealed bearing, which facilitates the extension and retraction of the drive roller.

[0007] Furthermore, the fixing component includes a fixing seat and studs. The outer surface of the rotating seat is provided with a fixing seat on the side away from the center of the roller. The screw holes on the upper and lower sides of the fixing seat are threaded with studs to facilitate the fixing of the rotating seat.

[0008] Furthermore, the fixing component also includes threaded holes and knobs. Threaded holes are provided on the upper and lower sides of both the left and right sides of the roller. The outer surface of the end of the stud closest to the center of the roller is threadedly connected to the corresponding threaded hole. A knob is provided on the end of the stud away from the center of the roller to facilitate fixing the rotating seat.

[0009] Furthermore, bearing seats are provided on both the left and right sides of the roller, and evenly distributed positioning holes are provided on the side of each bearing seat. A bearing is installed in the inner hole of the bearing seat. The outer diameter of the outer ring of the bearing is smaller than the inner diameter of the bearing seat, which facilitates the overall installation of the bearing into the bearing seat and ensures coaxiality during installation.

[0010] Furthermore, the outer surface of the roller shaft away from the center of the roller is fitted with a bearing on the same side. The diameter of the roller shaft is larger than the inner ring diameter of the bearing, which facilitates a tight fit through interference fit to transmit torque and load.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-load-bearing, low-resistance electric cone roller has the following advantages: Rotating the rotating seat drives the adjusting block to rotate. Under the guidance and limiting action of the rib groove and rib, the roller shaft moves along the cavity through the threaded groove, allowing the roller shaft to retract into the roller cavity. After the shaft retraction, the overall length of the tapered roller is shortened, eliminating the need to reserve installation stroke space for the roller shaft. This allows the tapered roller to quickly align with the bearing seat, making it suitable for narrow spaces and dense installations. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-6 This embodiment provides a technical solution: a high load-bearing, low-resistance electric conical roller, including a roller 1, with adjustable roller shafts 2 on both the left and right sides inside the roller 1, and also including an adjustment mechanism 3; Adjustment mechanism 3 includes a chamber 31, rib grooves 32, ribs 33, threaded grooves 34, adjusting blocks 35, a drive assembly 36, and a fixing assembly 37. Chambers 31 are provided on both the left and right sides of the roller 1. Ribs 32 are evenly distributed on the inner wall of each chamber 31 near the center of the roller 1. Roller shafts 2 are slidably connected inside each chamber 31. Ribs 33 are provided on the outer surface of each roller shaft 2 near the center of the roller 1, and each rib 33 is slidably connected to the rib grooves 32 on the same side. Threaded grooves 34 are provided on the outer surface of each roller shaft 2, and adjusting blocks 35 are threadedly connected to the outer surface of each threaded groove 34 via the drive assembly 36. Fixing assemblies 37 are provided on both the left and right sides of the roller 1, and a cone is installed. When rolling, first turn the knob 374 to drive the stud 372 to rotate, so that the stud 372 leaves the threaded hole 373, which can release the fixation of the rotating seat 361. Then, rotate the rotating seat 361. Under the restriction of the sealed bearing 363 in the clearance groove 362, the rotating seat 361 drives the adjusting block 35 to rotate. Under the guiding and limiting action of the rib groove 32 and rib 33, the rotation of the adjusting block 35 drives the roller shaft 2 to slide along the cavity 31 through the threaded groove 34 of the threaded connection, so that the roller shaft 2 retracts into the cavity 31 of the roller 1, aligning the roller shaft 2 with the central axis of the bearing 5 in the bearing seat 4. Rotate the rotating seat 361 in the opposite direction, so that the roller shaft 2 extends out of the roller 1 until the roller shaft 2 is inserted into the inner ring of the bearing 5. Roller 1 is shaped like a frustum with a diameter on the left side larger than that on the right side. The depth of the chamber 31 at the large end of roller 1 is greater than that at the small end of roller 1. This ensures that the roller shaft 2 is subjected to uniform force during extension and retraction, without affecting the load-bearing and guiding performance of the tapered roller, and ensuring the stability and force balance of the tapered roller during operation. The drive assembly 36 includes a rotating seat 361, a clearance groove 362, and a sealed bearing 363. The rotating seat 361 is located on the side of the adjusting block 35 away from the center of the roller 1. A sealing ring can be provided on the inner wall of the rotating seat 361. The outer surface of the sealing ring is in contact with the inner wall of the rotating seat 361, and the inner wall of the sealing ring is in contact with the outer surface of the roller 2. The sealing ring cooperates with the sealed bearing 363 to prevent dust and oil from entering the chamber 31, thus avoiding affecting the threaded transmission of the threaded groove 34 and the adjusting block 35. All outer surfaces of 361 are provided with clearance grooves 362, and all clearance grooves 362 are provided with sealed bearings 363. All rotating seats 361 are rotatably connected to the interior of the chamber 31 on the same side through the sealed bearings 363. The inner wall of the inner ring of the sealed bearing 363 is in contact with the inner wall of the clearance groove 362, and the outer surface of the outer ring of the sealed bearing 363 is in contact with the inner wall of the chamber 31. When rotating the rotating seat 361, under the restriction of the sealed bearings 363 in the clearance groove 362, the rotating seat 361 drives the adjusting block 35 to rotate. The fixing component 37 includes a fixing seat 371 and a stud 372. The outer surface of the rotating seat 361 is provided with a fixing seat 371 on the side away from the center of the roller 1. The stud 372 is threaded into the screw holes on the upper and lower sides of the fixing seat 371. The fixing component 37 also includes a threaded hole 373 and a knob 374. The upper and lower sides of the left and right sides of the roller 1 are provided with threaded holes 373. The outer surface of the end of the stud 372 near the center of the roller 1 is threaded into the corresponding threaded hole 373. The end of the stud 372 away from the center of the roller 1 is provided with a knob 374. At this time, the stud 372 on the fixing seat 37 corresponds to the threaded hole 373 on the roller 1. Then, the knob 374 is rotated in the opposite direction, and the stud 372 is screwed into the corresponding threaded hole 373 through thread engagement. The rotating seat 361 is fixed by the fixing seat 371 to prevent the roller shaft 2 from accidentally extending or retracting during operation. The roller 1 is provided with bearing seats 4 on both the left and right sides. The side of the bearing seats 4 is provided with evenly distributed positioning holes 6. The bearing 5 is provided in the inner hole of the bearing seat 4. The outer diameter of the outer ring of the bearing 5 is smaller than the inner diameter of the bearing seat 4, which makes it easy for the bearing 5 to be installed into the bearing seat 4 as a whole, while ensuring the coaxiality of the installation. The bearing seat 4 and the bearing 5 are installed together through the positioning holes 6 in a suitable position using fixing bolts. The outer surface of the roller 2, away from the center of the roller 1, is fitted with the bearing 5 on the same side. The diameter of the roller 2 is larger than the inner ring diameter of the bearing 5. The tight fit is achieved through interference fit to transmit torque and load.

[0016] The working principle of the high-load, low-resistance electric tapered roller provided by this utility model is as follows: The bearing housing 4, together with the bearing 5, is installed in a suitable position through the positioning hole 6 using fixing bolts. When installing the tapered roller, first rotate the knob 374 to drive the stud 372 to rotate, causing the stud 372 to leave the threaded hole 373, thus releasing the fixation on the rotating seat 361. Then, rotate the rotating seat 361. Under the restriction of the bearing 363 sealed in the clearance groove 362, the rotating seat 361 drives the adjusting block 35 to rotate. Under the guiding and limiting action of the rib groove 32 and the rib 33, the rotation of the adjusting block 35 drives the roller shaft 2 to slide along the cavity 31 through the threaded groove 34. This causes the roller shaft 2 to retract into the cavity 31 of the roller 1, aligning the roller shaft 2 with the central axis of the bearing 5 in the bearing housing 4. Rotating the rotating seat 361 in the opposite direction causes the roller shaft 2 to extend out of the roller 1 until it inserts into the inner ring of the bearing 5. Because the diameter of the roller shaft 2 is larger than the inner ring diameter of the bearing 5, a tight fit is achieved through interference, transmitting torque and load. At this time, the stud 372 on the fixed seat 37 corresponds to the threaded hole 373 on the roller 1. Then, rotating the knob 374 in the opposite direction causes the stud 372 to screw into the corresponding threaded hole 373 through thread engagement. The fixed seat 371 then secures the rotating seat 361, preventing the roller shaft 2 from accidentally extending or retracting during operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
