Description

Technical Field

[0001] This utility model relates to, specifically to, a roller support device and a conveyor. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, postal services, printing, and food for the assembly, testing, debugging, packaging, and transportation of goods. Belt conveyors feature high conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. They utilize the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100 kg or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can convey materials uphill and downhill.

[0003] After a period of use, the conveyor belt of a belt conveyor may deform due to prolonged pressure. In this case, a support structure is usually installed under the conveyor belt to make full use of the conveyor belt and extend its service life.

[0004] However, the existing support structure is fixed, while the deformation of the conveyor belt is continuous. This fixed support structure is not easy to adjust and cannot effectively cope with the continuous deformation of the conveyor belt. When the conveyor belt is transporting different materials, it is sometimes necessary to adjust the support structure, and the fixed support structure is not convenient for adjustment in this case.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem of fixed support structures being difficult to adjust, this invention provides a roller support device that allows for flexible adjustment of the roller position, thereby achieving better support for the conveyor belt.

[0027] Please see Figure 1 and Figure 2 , Figure 1 This is a side view of the roller support device provided in an embodiment of the present utility model; Figure 2 This is a partial front view of the roller support device provided in an embodiment of the present invention. The roller support device includes a telescopic mechanism 1, a rotating mechanism 2, and a roller mechanism 3.

[0028] The telescopic mechanism 1 is arranged on the side of the conveyor belt 4, and the telescopic direction of the telescopic mechanism 1 is perpendicular to the conveyor belt 4.

[0029] The rotating mechanism 2 includes a first part 21, a second part 22 and a locking member 23. The first part 21 and the second part 22 are rotatable relative to each other. The locking member 23 is detachably connected to the first part 21 and the second part 22 to fix the relative position of the first part 21 and the second part 22. The first part 21 is fixedly connected to the telescopic end of the telescopic mechanism 1.

[0030] The roller mechanism 3 includes a roller 31 and a roller 32. The roller 31 is eccentrically connected to the second part 22. At least one roller 32 is rotatably connected to the roller 31. The roller 32 abuts against the lower surface of the conveyor belt 4 to support the conveyor belt 4.

[0031] The telescopic mechanism 1 can adjust the position of the roller 32 over a wide range with low precision, while the rotating mechanism 2 can adjust the position of the roller 32 over a small range with high precision. By using the telescopic mechanism 1 and the rotating mechanism 2, the position of the roller 32 can be easily adjusted, thereby providing better support for the conveyor belt 4 according to the actual situation.

[0032] In some embodiments, the telescopic mechanism 1 includes a mounting tube 11 and a telescopic rod 12. The mounting tube 11 has a threaded through hole perpendicular to the conveyor belt 4. The outer surface of the telescopic rod 12 has a corresponding external thread. The telescopic rod 12 passes through the threaded through hole and engages with it threadedly. One end of the telescopic rod 12 is connected to the rotating mechanism 2. The other end of the telescopic rod 12 can be provided with a rotating handle 13, thereby facilitating the rotation of the telescopic rod 12 and realizing its telescopic function.

[0033] The rotating mechanism 2 includes a first part 21, a second part 22, and a locking member 23. In some embodiments, the first part 21 includes a first disk 211 with a plurality of first through holes evenly distributed along its circumference. The second part 22 includes a second disk 221 with a plurality of second through holes evenly distributed along its circumference. The first disk 211 and the second disk 221 are coaxially arranged, with the first through holes corresponding one-to-one with the second through holes. The locking member 23 is detachably inserted into the first and second through holes. By removing the locking member 23, manually rotating the second disk 221 to a suitable position, and then inserting the locking member 23 again, the rotation adjustment can be completed. It is easy to understand that multiple locking members 23 can be used for a stable connection.

[0034] Please see Figure 3 , Figure 3 yes Figure 2A cross-sectional view at point A. In some embodiments, the first part 21 further includes a first connecting part 212, which is fixedly connected to the first disk 211. The first connecting part 212 also forms an annular groove 212A, and one end of the telescopic rod 12 forms a corresponding protrusion 12A. The protrusion 12A is embedded in the annular groove 212A so that the telescopic rod 12 rotatably abuts against the first connecting part 212. The telescopic rod 12 rotates during extension and retraction. The connection between the protrusion 12A and the annular groove 212A provides the degree of freedom of rotation, so that the telescopic rod 12 only transmits linear motion to the rotating mechanism 2.

[0035] In some embodiments, the second part 22 further includes a second connecting portion 222, which is fixedly connected to the second disk 221 and detachably connected to the roller 31, such as by a threaded connection or a pin connection. The axis of the roller 31 is parallel to but eccentrically arranged with respect to the axis of the second disk 221. When the second disk 221 rotates, the position of the roller 32 can be changed.

[0036] Please see Figure 4 , Figure 4 yes Figure 2 A cross-sectional view at point B. In some embodiments, the roller mechanism 3 further includes a bearing 33, through which the roller 32 is rotatably mounted on the roller shaft 31. The bearing reduces friction between the roller and the roller shaft.

[0037] Based on the aforementioned embodiments, the roller mechanism 3 further includes a fixing member 34. The surface of the roller 31 has an external thread, and the fixing member 34 has a corresponding threaded hole. The fixing member 34 can be sleeved onto the roller 31 and engaged with the thread. A gap is formed between the bearing 33 and the roller 31, and the fixing member 34 can be partially inserted into the gap to securely connect the roller 31 and the bearing 33. By providing the fixing member 34, the roller 32 can be easily and quickly disassembled and replaced to meet a wider range of application scenarios.

[0038] In some embodiments, a roller 32 is sleeved on a roller 31 via two bearings 33. The roller 31 has at least one pair of external threads with opposite directions of rotation. Two fasteners 34 are respectively engaged with the roller and correspond to the two bearings 33.

[0039] In a preferred embodiment, the conveyor belt 4 drives the roller 32 to rotate in the same direction as the two fixing members 34 rotate when they come together. This ensures that the fixing members 34 will gradually tighten during use, preventing them from automatically coming loose.

[0040] In some embodiments, the roller support device includes two telescopic mechanisms 1, two rotating mechanisms 2, and a roller mechanism 3. The two telescopic mechanisms 1 and the two rotating mechanisms 2 are symmetrically arranged on both sides of the tree hole belt 4 and connected to both ends of the roller 31. The roller 31 is provided with a plurality of rollers 32, each roller 32 corresponding to two bearings 33 and two fixing members 34.

[0041] Please see again Figure 1 This utility model also provides a conveyor, including a roller support device, a conveyor belt 4, and a frame 5. The telescopic mechanism 1 is fixedly connected to the frame 5, specifically, the mounting pipe 11 is fixedly connected to the frame 5, and the connection method can be screws or welding. The rollers 32 abut against the lower surface of the material-carrying part of the conveyor belt 4, thereby supporting the conveyor belt 4.
