Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a height-adjustable electric roller. Background Art

[0002] In the field of material transportation and processing, electric rollers are widely used. Traditional electric rollers are fixed in height and difficult to adapt to production lines or transportation scenarios of different heights. They often need to be adjusted with the help of complex external devices, which increases costs and space occupancy. In addition, most of the rollers are fixedly connected and sealed structures. When handling sticky and easily residual materials, dirt and impurities are easily accumulated inside, affecting the rotation balance and transportation efficiency of the roller, and even causing material contamination and equipment failure due to failure to clean in time;

[0003] However, with the improvement of industrial automation and the requirements for refined material handling, expectations for the flexibility and maintainability of electric rollers are rising. Therefore, it has become an urgent task to develop an electric roller that is highly adjustable and easy to open for internal cleaning, in order to meet the needs of modern industry for efficient, convenient and clean production and improve the overall performance and reliability of the material conveying process.

[0004] Chinese patent (publication number CN104555323B), this patented technology discloses an electric roller, which can rotate without an external motor and a reduction box, and is powered by a built-in electric motor.

[0034] Example 1: Please refer to Figure 1-2 In an embodiment of the present invention, a height-adjustable electric roller comprises two groups of conveying cylinders 1, the two groups of conveying cylinders 1 are symmetrically distributed, wherein the right end of the conveying cylinder 1 on the right side is fixedly installed with a first driving motor 9, and a conveying mechanism 301 for conveying materials is fixedly installed between the two groups of conveying cylinders 1, and the opposite ends of the two groups of conveying cylinders 1 are fixedly connected with a bellows 11, and the bellows 11 is made of rubber material, which has good elasticity, good high temperature resistance and corrosion resistance, and is durable. The two groups of bellows 11 are connected by a trigger closing mechanism 201, and the conveying direction of the conveying cylinder 1 is adjusted by adjusting the angle between the two groups of conveying cylinders 1, and the conveying cylinder 1 has a limiting function, and the outer wall of the right conveying cylinder 1 is fixedly connected with a feeding port 6, and the feeding port 6 is funnel-shaped, so that the feeding port 6 can better receive the material;

[0035] The bottom of the two groups of conveying cylinders 1 are both provided with a mounting base 5, and the internal threaded connection of the mounting base 5 is connected with a plurality of threaded nails 4. When it is necessary to limit the mounting base 5, it is only necessary to abut the mounting base 5 against the ground, and then limit and fix the mounting base 5 to the ground through the threaded nails 4. A weight reduction opening is also opened inside the mounting base 5, which effectively reduces the overall weight of the threaded nails 4. The upper end of the mounting base 5 is fixedly connected to the first electric telescopic rod 2, and the upper end of the mounting base 5 is rotatably connected to the second electric telescopic rod 3. The second electric telescopic rod 3 and the first electric telescopic rod 2 are symmetrically distributed on the upper end of the mounting base 5.

The outer wall of the abutting block 39 is provided with a curved surface, which can effectively reduce the friction between the abutting block 39 and the abutting ball 40.

[0042] The working principle of the present invention is:

[0043] When the present invention is used, the first drive motor 9 is started to drive the corresponding transmission shaft 8 to rotate, the transmission shaft 8 drives the first rotating block 12 to rotate through the second elastic telescopic tube 14, the first rotating block 12 drives the second rotating block 41 to rotate through the rotating rectangular block 15, the second rotating block 41 drives the first elastic telescopic tube 13 to rotate, the first elastic telescopic tube 13 can drive another group of transmission shafts 8 to rotate through the above working principle, and each group of transmission shafts 8 will drive the spiral piece 7 to rotate when it rotates. At this time, the material is poured into the conveying cylinder 1 through the feeding port 6, and the spiral piece 7 can guide the material;

[0044] When the angle of the conveying cylinder 1 needs to be adjusted, the second driving motor 23 is started, the second driving motor 23 will drive the recovery wire wheel 24 to rotate, and the recovery wire wheel 24 will release the pull on the contact rope 26. At this time, all the third elastic telescopic tubes 42 will drive the moving block 21 and the matching arm 44 to reset and move, and the matching arm 44 will drive the active air plug 30 to move, and the active air plug 30 will make a suction action inside the connecting air box 27, and the connecting air box 27 will drive the pneumatic telescopic tube 38 to extract air from the inside through the connecting air pipe 29, and the air The movable telescopic tube 38 drives the abutment block 39 to disengage from the abutment with the abutment ball 40, and the second spring 37 drives the latching teeth 36 to move. When all the latching teeth 36 are disengaged from the abutment with the limiting toothed ring 34, the second rotating arm 35 and the first rotating arm 31 are released from restriction. At this time, the first rotating arm 31 and the second rotating arm 35 can rotate, and the two groups of conveying cylinders 1 can be rotated. Since the two groups of conveying cylinders 1 are rotatably connected through multiple groups of first abutment rings 17 and second abutment rings 18, when one group of conveying cylinders 1 is rotated, it can be rotated at multiple angles.

[0045] For example, when one set of conveying cylinders 1 rotates upward, the first rotating arm 31 and the second rotating arm 35 at the bottom will be pulled and straightened, while the first rotating arm 31 and the second rotating arm 35 at the top will be bent, and when rotating to the left, the connecting ring 16 can be rotated and then rotated;

[0046] It is worth noting that when the two sets of conveying cylinders 1 change their angles, the distance between the two sets of transmission shafts 8 inside will increase accordingly. At this time, the first elastic telescopic tube 13 can be freely stretched according to the distance between the two sets without being affected in any way.

[0047] At the same time, when the moving block 21 drives the limiting block 19 to disengage from the clamping ring 22, the two sets of first abutting rings 17 and second abutting rings 18 can be moved, and the two sets of bellows 11 can be contracted, so that the spiral sheet 7 and the transmission shaft 8 inside the conveying cylinder 1 can be cleaned through the interval between the two sets of bellows 11;

[0048] When the adjustment and cleaning are completed, the first abutment ring 17 and the second abutment ring 18 need to be closed to each other, and the recovery wire wheel 24 only needs to be driven by the second driving motor 23 to rotate in the opposite direction, and the recovery wire wheel 24 will abut the rope 26 to pull, and the abutment rope 26 drives all the moving blocks 21 to move. When the moving block 21 is reset, the moving block 21 will drive the movable air plug 30 to reset through the matching arm 44. At this time, the connecting air box 27 will inflate the inside of the pneumatic telescopic tube 38, and the pneumatic telescopic tube 38 will drive all the clamping teeth 36 to reset and engage with the inner wall of the limiting tooth ring 34 through the abutment block 39, completing the limiting of the first rotating arm 31 and the second rotating arm 35, and the angle limit adjustment of the two groups of conveying cylinders 1 can be achieved. When the moving block 21 is reset, it will also drive the clamping of the limiting clamping block 19 and the clamping ring 22 to complete the limiting, which is convenient and quick;

[0049] When the second electric telescopic rod 3 and the first electric telescopic rod 2 cannot adjust the angle when the conveying cylinder 1 is rotated, the bolts can be removed and they can be limited by other means so that the conveying cylinder 1 can change more angles.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
