Description

Technical Field

[0001] This application relates to the technical field of conveyor belts, and particularly to a PVG flame-retardant solid-core conveyor belt. Background Art

[0002] PVG conveyor belts are often used for the mechanized transportation of agricultural products such as food due to their flexibility, tear resistance, and chemical corrosion resistance. In actual use, due to the uncertainty of the conveying distance, in some occasions with longer conveying distances, a single conveyor belt cannot meet the usage requirements due to length limitations. Therefore, joints are needed to connect multiple conveyor belts to form a stable closed-loop ring-shaped conveyor belt, and then the objects on the top of the conveyor belt are driven to move through the transmission of rollers.

[0003] As shown in the patent with the Chinese patent publication number CN215665380U, there are still the following deficiencies in actual use: When the joint of the PVG flame-retardant solid-core conveyor belt of the above patent is actually used, the conveyor belt is conveyed by two plate members to fix both ends of the conveyor belt. By the way of driving the plate members to move vertically by a rod member, the stress is mainly concentrated at the position where the plate member is away from the rod member, so that the clamping stress is too concentrated. And during the use of the conveyor belt, there is a pulling force at both ends on the clamping part, so that the end part during clamping breaks due to excessive tension during use, thus triggering a safety accident. When the conveyor belt suddenly breaks and is subjected to a pulling force, it will suddenly swing out, which is likely to cause harm to the surrounding staff or equipment. When the conveyor belt breaks, the staff cannot observe it in time to avoid or stop the machine for maintenance. Summary of the Invention

[0028] The following is a further detailed description of this application in combination with the attached Figures 1 - 12 drawings.

[0029] An embodiment of the present application discloses a PVG flame-retardant solid-core conveyor belt.

[0030] Refer to Figure 1 , a PVG flame-retardant solid-core conveyor belt includes a connecting bottom plate 1, side plates 11 are fixedly connected to the top of the connecting bottom plate 1, a safety warning mechanism 2 is arranged on the outer wall of the connecting bottom plate 1, the safety warning mechanism 2 includes a sliding block 211 arranged on the side wall of the side plate 11, a rope 219 is arranged on the outer wall of the sliding block 211, a connecting plate two 222 is arranged on the outer wall of the side plate 11, a trigger block 226 is arranged at the end of the rope 219, a driving member 231 is arranged on the top of the trigger block 226, a spring two 233 is fixedly arranged on the side wall of the driving member 231, a fixing strip 236 is arranged on one side of the connecting plate two 222, a connecting rod one 243 is arranged on the side wall of the sliding block 211, a sliding strip two 245 is arranged on the side of the connecting rod one 243 away from the sliding block 211, a connecting rod two 247 is arranged on the side wall of the sliding strip two 245, a warning board 249 is fixedly arranged on the top of the connecting rod two 247, the safety warning mechanism 2 further includes a lower pressing plate 21 attached to the inner wall of the side plate 11, a fixing plate 22 is fixedly connected to the top of the side plate 11, a first threaded hole is formed through the top of the fixing plate 22, a lower pressing screw 23 is threadedly penetrated through the first threaded hole, so that the lower pressing screw 23 is threadedly connected to the fixing plate 22, so that when a staff member rotates the fixing plate 22, the fixing plate 22 will drive the lower pressing plate 21 to move vertically downward, so as to squeeze the conveyor belt from the top of the conveyor belt.

[0031] The staff first turns the rotating plate 240 into a vertical state, and then passes the two ends of the conveyor belt through the square frame 252 so that the two ends are aligned on the top of the connecting bottom plate 1.

[0032] Refer to Figures 2 - 3, the first limiting plate 24 is fixedly connected to the outer wall of the side plate 11, the first limiting strip 25 is fixedly connected to the side of the first limiting plate 24 away from the side plate 11, the top of the first limiting strip 25 is at the same height as the top of the first limiting plate 24, the second limiting strip 26 is fixedly connected to the side of the first limiting plate 24 away from the side plate 11, and the bottom of the second limiting strip 26 is at the same height as the bottom of the first limiting plate 24. A horizontal sliding groove one is formed through the side wall of the first limiting plate 24, and the sliding cylinder 27 movably passes through the horizontal sliding groove one, so that the first limiting plate 24 is slidably connected to the sliding cylinder 27. A circular hole one is formed through the side wall of the first connecting plate 28, and the side wall of the sliding cylinder 27 fixedly passes through the circular hole one, so that the first connecting plate 28 is rotatably connected to the circular hole one. The limiting disc 29 is fixedly connected to the end of the sliding cylinder 27 away from the first limiting plate 24. A horizontal sliding groove two is formed through the side wall of the second limiting plate 210, and the outer wall of the sliding cylinder 27 movably passes through the horizontal sliding groove two, so that the sliding cylinder 27 is slidably connected to the second limiting plate 210. The side of the second limiting plate 210 close to the second limiting strip 26 is fixedly connected to the second limiting strip 26, and the side of the first limiting strip 25 away from the first limiting plate 24 is fixedly connected to the side wall of the second limiting plate 210.

[0033] The staff places the lower pressing plate 21 at the bottom of the fixing plate 22, rotates the lower pressing screw 23 to clamp the end of the conveyor belt, and then rotates the rotating plate 240 to further fix the conveyor belt through friction by the cushion block 241 to complete the end connection.

[0034] Refer to Figures 4 - 5, there is a certain space between the bottom of the second limiting strip 26 and the top of the first connecting plate 28, and there is also a certain space between the top of the first limiting strip 25 and the bottom of the first connecting plate 28. Thus, the first connecting plate 28 can drive the sliding cylinder 27 to rotate within a small range in the vertical direction, so as to adapt to the vibration of the conveyor belt and to adapt to the arc of the side wall of the roller when passing through the roller. A circular hole cavity one is provided in the inner wall of the sliding block 211, and the limiting disc 29 is clamped with the circular cavity one, so that the limiting disc 29 can rotate inside the sliding block 211. A non-through circular hole two is provided in the side wall of the sliding block 211, and the sliding cylinder 27 is inserted into the circular hole two, so that the sliding cylinder 27 is rotatably connected with the sliding block 211. The connecting component 212 is fixedly connected to the side wall of the second limiting plate 210, and the outer wall size of the connecting component 212 is the same as the outer wall size of the second limiting plate 210, thus forming a more stable whole. One end of the first spring 213 close to the inner wall of the connecting component 212 is fixedly connected to the inner wall of the connecting component 212, and the other end of the first spring 213 away from the connecting component 212 is fixedly connected to the side wall of the abutting plate 214. The side wall of the abutting plate 214 is attached to the side wall of the sliding block 211, the bottom of the abutting plate 214 is attached to the top of the inner wall of the connecting component 212, the bottom of the abutting plate 214 is fixedly connected to the top of the slider 215, and a dovetail groove one is provided in the inner wall of the connecting component 212. The slider 215 is slidably connected with the dovetail groove one, so that the slider 215 limits the abutting plate 214, and the abutting plate 214 can only slide horizontally.

[0035] When the conveyor belt operates, the first connecting plate 28 reduces the vibration impact through small-range rotation. Since the lower pressing plate 21 is rigidly fixed, the edge of the connecting bottom plate 1 is easily worn after long-term use, resulting in a risk of fracture between the rotating plate 240 and the connecting bottom plate 1.

[0036] Refer to Figure 6, the limit bar three 216 is fixedly connected to the top of the sliding block 211, so that the limit bar three 216 and the sliding plate one 217 can move horizontally synchronously, the sliding plate one 217 is slidably connected to the top of the sliding block 211, and the sliding range of the sliding plate one 217 is limited by the two limit bars three 216 fixedly connected to the top of the sliding block 211. The top of the sliding plate one 217 fits with the bottom of the limit plate three 218, so that the sliding plate one 217 and the sliding block 211 always keep fit, the limit plate three 218 is fixedly connected to the side wall of the limit plate two 210, so that the limit plate three 218 is fixed to the limit plate two 210, and the end of the rope 219 close to the sliding plate one 217 is fixedly connected to the side wall of the sliding plate one 217, so that The sliding block 211 can move horizontally by means of the sliding plate 1 217 to pull the rope 219, and the side wall of the rope 219 fits with the outer wall of the pulley 220, so that when the rope 219 is pulled, the pulling force direction can be changed with the help of the pulley 220 to form a pulley block, and a round hole 3 is penetrated through the side wall of the pulley 220, and the fixed cylinder 221 movably penetrates the round hole 3, so that the pulley 220 is rotatably connected with the fixed cylinder 221, and the fixed cylinder 221 is fixedly connected to the side wall of the limiting plate 210, so that the fixed cylinder 221 is fixed by the limiting plate 210, and the end of the connecting plate 1 28 away from the sliding cylinder 27 is fixedly connected to the end of the connecting plate 222 close to the connecting plate 1 28, so that the connecting plate 222 and the connecting plate 1 28 rotate synchronously.

[0037] When the break occurs, the conveyor belt on the rotating plate 240 drives the connecting plate 222 away from the connecting bottom plate 1, and the connecting plate 1 28 moves horizontally. The connecting plate 1 28 drives the sliding cylinder 27 to drive the sliding block 211 to move, and finally the limiting strip 3 216 drives the sliding plate 1 217 to slide horizontally.

[0038] Reference Figure 7, the frame plate 223 is fixedly connected to the side wall of the second connecting plate 222. The outer wall dimensions of the frame plate 223 are the same as those of the outer wall of the second connecting plate 222. A circular hole four is formed through the side wall of the connecting component 212, and the rope 219 movably passes through the circular hole four. A circular hole five is formed through the side wall of the frame plate 223, and the rope 219 movably passes through the circular hole five, so as to facilitate the extension of the rope 219 into the interior of the frame plate 223. One end of the rope 219 close to the pulling plate 224 is fixedly connected to the side wall of the pulling plate 224. The bottom of the pulling plate 224 is attached to the inner wall of the frame plate 223. The second sliding plate 225 is fixedly connected to the side wall of the pulling plate 224. The bottom of the second sliding plate 225 is attached to the inner wall of the frame plate 223. The bottom of the trigger block 226 is fixedly connected to the top of the second sliding plate 225. The side wall of the trigger block 226 is set as an inclined surface. The bottom of the clamping plate 227 is fixedly connected to the inner wall of the frame plate 223. The side wall of the clamping plate 227 is attached to one side of the synchronous plate 228 close to the clamping plate 227. The side wall of the synchronous plate 228 is fixedly connected to the side wall of the first linkage block 229. The bottom of the first linkage block 229 is attached to the top of the second sliding plate 225. One side of the first linkage block 229 close to the trigger block 226 is set as an inclined surface. The first linkage block 229 and the trigger block 226 are adaptable, so that when the trigger block 226 moves horizontally, it can drive the first linkage block 229 to move vertically. The top of the first linkage block 229 is fixedly connected to the bottom of the sliding rod 230. A circular hole six is formed through the bottom of the driving member 231 in a non-through manner, and the sliding rod 230 is slidably connected to the circular hole six, so that when the first linkage block 229 moves vertically, the sliding rod 230 will slide inside the circular hole six.

[0039] The first sliding plate 217 pulls the rope 219 to drive the pulling plate 224 to move towards the connecting bottom plate 1. The pulling plate 224 drives the second sliding plate 225 and the trigger block 226 to move horizontally. The trigger block 226 triggers the first linkage block 229 to rise vertically, and then drives the synchronous plate 228 to release the attachment to the clamping plate 227.

[0040] Refer to Figures 8 - 9, one end of the telescopic rod 232 close to the driving member 231 is fixedly connected to the side wall of the driving member 231, and one end of the telescopic rod 232 away from the driving member 231 is fixedly connected to the inner wall of the frame plate 223. The second spring 233 is sleeved on the outer wall of the telescopic rod 232. One end of the second spring 233 close to the driving member 231 is fixedly connected to the driving member 231, and one end of the second spring 233 away from the driving member 231 is fixedly connected to the inner wall of the frame plate 223. Thus, the horizontal movement of the driving member 231 will drive the telescopic movement of the telescopic rod 232 and the compression and release of the second spring 233. The side wall of the driving member 231 is set as an inclined surface, and the upper end of the second linkage block 234 is set as an inclined surface. The inclined surface of the driving member 231 is in contact with the inclined surface of the second linkage block 234. Thus, the horizontal movement of the driving member 231 can drive the vertical movement of the second linkage block 234. The first sliding bar 235 is fixedly connected to the side wall of the second linkage block 234. Thus, the vertical movement of the second linkage block 234 can drive the first sliding bar 235 to move vertically synchronously. One end of the fixed bar 236 close to the first sliding bar 235 is fixedly connected to the top of the first sliding bar 235. Thus, the fixed bar 236 moves synchronously with the first sliding bar 235. One side of the fixed bar 236 close to the frame plate 223 is in contact with the side wall of the frame plate 223. Thus, the frame plate 223 limits the fixed bar 236. The supporting square column 237 is fixedly connected to the side wall of the second connecting plate 222. The bottom of the supporting square column 237 is fixedly connected to the top of the fixed cross bar 238. Thus, the supporting square column 237 is fixed by the fixed cross bar 238 and the second connecting plate 222.

[0041] At this time, the second spring 233 releases the compressed elastic force, drives the horizontal movement of the driving member 231, and the driving member 231 drives the second linkage block 234, the first sliding bar 235, and the fixed bar 236 to press down vertically, realizing the emergency fixation of the broken conveyor belt and preventing the harm of flapping.

[0042] Refer to Figure 10, both ends of the supporting cylinder 239 are fixedly connected to the side walls of the second connecting plate 222. A seventh round hole is formed through the side wall of the rotating plate 240, and the outer wall of the supporting cylinder 239 movably penetrates through the seventh round hole, so that the supporting cylinder 239 is rotatably connected to the rotating plate 240. The cushion block 241 is fixedly connected to the outer wall of the rotating plate 240. The cushion block 241 is made of rubber and has a rough surface, so as to increase the friction force with the surface of the conveyor belt. When the conveyor belt is pulled to both sides, the pulling force of the conveyor belt is opposite to the rotation direction of the rotating plate 240, so that the cushion block 241 squeezes the side wall of the conveyor belt to further increase the friction. The first connecting seat 242 is fixedly connected to the side of the sliding block 211 away from the abutting plate 214. An eighth round hole is formed through one end of the first connecting rod 243 close to the first connecting seat 242, and the side wall of the first connecting seat 242 is rotatably connected to the eighth round hole, so that the first connecting rod 243 is rotatably connected to the first connecting seat 242. A ninth round hole is formed through the end of the first connecting rod 243 away from the first connecting seat 242, and the ninth round hole is rotatably connected to the second connecting seat 244, so that the second connecting seat 244 is rotatably connected to the first connecting rod 243. The side wall of the second sliding bar 245 is fixedly connected to one end of the second connecting seat 244 close to the second sliding bar 245.

[0043] Synchronously, when the sliding block 211 moves horizontally, it pulls the first connecting seat 242, so that the first connecting rod 243 rotates from an inclined state to a horizontal state. The first connecting rod 243 pulls the second sliding bar 245 to rise vertically, drives the second connecting rod 247 to turn into an inclined state, and the linkage warning plate 249 completes the warning action.

[0044] Refer to Figures 11 - 12, the outer wall of the second sliding bar 245 is slidably connected to the connecting member 212, the limiting long plate 246 is fixedly connected to the inner wall of the connecting member 212, and the limiting long plate 246 is in contact with the second sliding bar 245, so that the limiting long plate 246 is slidably connected to the second sliding bar 245, so that the second sliding bar 245 can only move vertically. A ninth circular hole is formed through the top of the second sliding bar 245. One end of the second connecting rod 247 close to the second sliding bar 245 is fixedly penetrated with a first shaft body. The first shaft body movably penetrates through the ninth circular hole, so that the second connecting rod 247 is rotatably connected to the second sliding bar 245. One end of the second connecting rod 247 far from the second sliding bar 245 is fixedly penetrated with a second shaft body. A third horizontal sliding groove is horizontally formed through the side wall of the limiting block 248. The second shaft body movably penetrates through the third horizontal sliding groove, so that one end of the second connecting rod 247 far from the second sliding bar 245 is slidably connected to the limiting block 248. The outer wall of the limiting block 248 is fixedly connected to the connecting member 212. The bottom of the warning board 249 is fixedly connected to the top of the second connecting rod 247, so that the second connecting rod 247 can drive the warning board 249 to move synchronously. The surface of the warning board 249 is coated with reflective paint. The model of the reflective paint can be selected from the Orange9000 series of high weather-resistant orange industrial paint. Therefore, when the warning board 249 changes from a horizontal state to an inclined state, the paint will be more eye-catching through different angles of light irradiation. The first cover plate 250 is fixedly connected to the outer wall of the frame plate 223, and the second cover plate 251 is fixedly connected to the outer wall of the connecting member 212, so as to shield the internal structure through the second cover plate 251 and the first cover plate 250. The square frame 252 is fixedly connected to the side of the frame plate 223 away from the first cover plate 250, so as to support the pulley 220 through the square frame 252. A first square groove is formed through the top of the frame plate 223. The top of the driving member 231 is fixedly connected to the bottom of the reset strip 253. The reset strip 253 is slidably connected to the first square groove, so as to facilitate the reset of the driving member 231.

[0045] The whole set of safety mechanism is through multi-stage mechanical linkage. The fracture end is fixed by the fixed strip 236. The second connecting plate 222 remains connected to the first connecting plate 28 to limit the swinging range, forming a full-process protection from physical restraint to visual warning, and significantly reducing the risk of secondary hazards of fracture accidents.

[0046] The implementation principle of a PVG flame-retardant solid-core conveyor belt in an embodiment of the present application is as follows: After the staff vertically flips the rotating plate 240, the conveyor belt is passed through the square frame 252 and aligned at the top of the connecting bottom plate 1. The lower pressing plate 21 is placed at the bottom of the fixing plate 22. After clamping the end of the conveyor belt with the pressing screw 23, the rotating plate 240 is rotated to make the cushion block 241 frictionally fix the conveyor belt. The first connecting plate 28 can buffer vibration during operation. When the edge of the conveyor belt wears and breaks, the broken end drives the second connecting plate 222 to move horizontally, linking the first connecting plate 28, the sliding cylinder 27, the sliding block 211, the third limiting strip 216, the first sliding plate 217, the rope 219, the pulling plate 224, the second sliding plate 225, and the trigger block 226 to form a chain reaction, causing the first linkage block 229 to drive the synchronous plate 228 to release the contact with the clamping plate 227. The second trigger spring 233 releases elastic force to drive the driving member 231, the second linkage block 234, the first sliding strip 235, and the fixing strip 236 to fix the broken conveyor belt downward. At the same time, the first connecting seat 242 drives the first connecting rod 243 to turn into a horizontal state, driving the second sliding strip 245 and the second connecting rod 247 to form an inclined angle, driving the warning plate 249 to complete safety warning, and realizing the functions of double fixing of the broken end and risk warning.

For those skilled in the art, the present disclosure can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
