Description

Technical Field

[0001] This invention relates to the field of conveyor belt idler structure technology, and in particular to an idler device. Background Technology

[0002] When transporting objects, conveyor belts are often used. A typical conveyor belt consists of a main support frame, two drive rollers, several idlers, a motor, and a rubber belt. When it is working, the motor drives one of the drive rollers to rotate, which in turn drives the rubber belt. Several idlers support the middle section of the rubber belt.

[0003] However, existing conveyor belts experience thermal expansion and contraction in cold weather, causing the rubber belt to tighten. This can easily lead to cracking or even breakage when transporting heavy objects, especially in northern my country where winter temperatures can drop to below -40 degrees Celsius. When the conveyor belt is placed outdoors, the operator needs to heat the rubber belt before starting it. Since rubber belts are of a certain length, this requires the operator to spend a lot of time waiting for the conveyor belt to heat up, which affects the working efficiency of the conveyor belt. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a roller device, comprising,

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a roller device, including,

[0033] The support mechanism 100 includes a conveyor belt main frame 101, a first rotating roller 102 disposed on the top of one side of the conveyor belt main frame 101, a second rotating roller 103 disposed on the top of the other side of the conveyor belt main frame 101, a rubber belt 104 sleeved on the outer walls of the first rotating roller 102 and the second rotating roller 103, cams 105 disposed on both sides of the second rotating roller 103, and a transmission mechanism 200, including a support frame 201 and a support roller 202 rotatably connected to the outer wall of the support frame 201. The first rotating roller 102 is connected to a motor. During the transmission operation, the first rotating roller 102 rotates and drives the second transmission roller 103 to rotate through the rubber belt 104. At this time, the rubber belt 104 can move the object, and the support roller 202 will support the middle area of ​​the rubber belt 104 and give it sufficient support force.

[0034] The fixed compartment 203 is connected to the top of the support frame 201, the sliding plate 204 is slidably connected to the top of the fixed compartment 203, and the sliding rod 205 is connected to one side of the sliding plate 204. The sliding plate 204 has a C-shaped cross-sectional area and is located in the groove of the fixed compartment 203. Protrusions are provided on both sides of the fixed compartment 203 to restrict the sliding plate 204 from moving up and down. The top of the fixed compartment 203 and the sliding plate 204 are both made of hard alloy.

[0035] The outer walls of the sliding rod 205 are slidably connected to the inner walls of the fixed chamber 203 on both sides. Each inner wall of the fixed chamber 203 is provided with a first elastic component 206, which is a threaded spring. The other end of the first elastic component 206 is connected to one side of the sliding rod 205. A copper plate 207 is provided at the bottom of the fixed chamber 203. A heat-conducting pipe 208 is installed at the bottom of the copper plate 207, and a heat dissipation plate 209 is provided at the bottom of the heat-conducting pipe 208. Both the heat-conducting pipe 208 and the heat dissipation plate 209 are made of copper alloy. Plate 209 is located above rubber belt 104. Cam 105 is flower-shaped. The outer wall of rolling wheel 304 is in rolling connection with the outer wall of cam 105. Linkage mechanism 300 is connected to sliding plate 204. Linkage mechanism 300 includes a connecting seat 301 rotatably connected to one side of sliding plate 204, a limiting rod 302 rotatably connected to one side of connecting seat 301, a rotating rod 303 rotatably connected to one side of limiting rod 302, and a rolling wheel 304 rotatably connected to one end of rotating rod 303. When cam 105 rotates, it drives the rolling wheel 304. The rotating wheel 304 rolls, and the protruding part of the cam 105 pushes the rotating wheel 304 backward, causing the rotating rod 303 to move. This ultimately causes the sliding plate 204 to move, and the sliding plate 204 rubs against the top of the fixed chamber 203. When the groove of the cam 105 contacts the rotating wheel 304, the rotating rod 303 moves again, and the sliding plate 204 moves again. This back-and-forth friction between the sliding plate 204 and the fixed chamber 203 generates a large amount of heat. The heat will be conducted to the heat pipe 208 and the heat sink 209. Since the heat sink 209 is relatively close to the rubber strip 104, the rubber strip 104 can be baked through the heat sink 209 to heat the rubber strip 104. This eliminates the need for the user to heat the rubber strip 104. At the same time, multiple heat sinks 209 can heat the rubber strip 104 simultaneously, which can quickly heat the entire rubber strip 104, thereby accelerating the heating of the rubber strip 104 and reducing the heating time required for the rubber strip 104.

[0036] Example 2

[0037] Reference Figures 6-8This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a sliding cavity 210 is provided on the side of the fixed chamber 203 away from the first elastic component 206. The sliding cavity 210 is cylindrical in shape, and the width of the limiting rod 302 is the same as the diameter of the sliding cavity 210. A first sliding groove 211 is provided on one side of the sliding cavity 210. One side of the sliding plate 204 is slidably connected to the inner wall of the first sliding groove 211. A second sliding groove 212 is provided at the bottom of the sliding cavity 210. The first sliding groove 211 and the second sliding groove 212 are perpendicular to each other, and the width of the first sliding groove 211 is greater than the width of the second sliding groove 212. The connecting seat 301 and the limiting rod 302 are both located in the sliding cavity 210. The thickness of the limiting rod 302 is greater than the width of the first sliding groove 211 and less than the width of the second sliding groove 212. The rotating rod 303 is rotatably connected to the limiting rod 302 through a rotating shaft. At the same time, the two sides of the rotating shaft extend out from the two sides of the limiting rod 302.

[0038] A limiting mechanism 400 is provided on the outer wall of the limiting rod 302. The limiting mechanism includes a rotating seat 401 connected to one side of the rotating rod 303, a bolt 402 threadedly connected to the inner wall of the rotating seat 401, a limiting seat 403 threadedly connected to the bolt 402, limiting grooves 404 formed on both sides of the limiting seat 403, and threaded holes 405 formed on the upper and lower sides of the limiting seat 403. The inner wall of the limiting seat 403 is slidably connected to the outer wall of the limiting rod 302, and one side of the limiting seat 403 is connected to the rotating rod. 303 are in contact with each other on one side. Once the rubber belt 104 has finished heating, there is no need to continue heating the rubber belt 104. At this point, the conveyor belt can be stopped, the bolt 402 can be removed, and the limiting seat 403 can be moved away from the rotating seat 401. Then, the limiting rod 302 and the rotating rod 303 are rotated 90 degrees. Then, the limiting rod 302 and the rotating rod 303 are rotated again, and then the rotating rod 303 is rotated again, so that the limiting rod 302 and the rotating rod 303 form a whole. Figure 8 The shape of the middle part is made to form an L-shape. Then, the limiting seat 403 is pushed down so that the limiting groove 404 locks the rotating shaft on the rotating rod 303, so that the rotating rod 303 and the limiting rod 302 maintain an L-shape. At this time, the rotating rod 303 will contact the bottom of the rubber belt 104. In this way, when the rubber belt 104 moves, the rotating rod 303 can catch the debris on the rubber belt 104, making it convenient for the user to clean the surface of the rubber belt 104.

[0039] A triangular fixed seat is provided at the bottom of the limiting seat 403. After the limiting groove 404 locks the rotating shaft on the rotating rod 303, the fixed seat will contact the top of the rubber belt 104. In this way, the fixed seat and the rotating rod 303 can "support" the rubber belt 104, thereby preventing the rubber belt 104 from shifting when moving.

[0040] Example 3

[0041] Reference Figure 9 This is the third embodiment of the present invention. Based on the previous embodiment, the difference is that a lubrication mechanism 500 is provided on one side of the fixed chamber 203. The lubrication mechanism 500 includes a storage chamber 501 connected to the bottom of the fixed chamber 203, a rotating roller 502 rotatably connected to the bottom of the fixed chamber 203, and an inclined groove 503 formed on the surface of the rotating roller 502. To prevent overheating due to friction between the fixed chamber 203 and the sliding plate 204, the rotating roller 502 can be rotated when the sliding plate 204 moves and contacts it. The inclined groove 503 on the rotating roller 502 is inclined towards... The limiting mechanism 400 is inclined. When the sliding plate 204 moves in the direction of the limiting mechanism 400, the rotating roller 502 will also rotate toward the limiting mechanism 400. Since there is lubricating oil in the storage chamber 501, the inclined groove 503 can bring a small amount of lubricating oil into the fixed chamber 203 and the sliding plate 204 each time, providing a certain amount of lubrication for the fixed chamber 203 and the sliding plate 204. At the same time, the fixed chamber 203 is inclined as a whole, and the height of the side where the rotating roller 502 is set is greater than the height of the other side, so as to facilitate the flow of lubricating oil to other positions.
