Description

Technical Field

[0001] This invention relates to the field of bagged cement palletizing, and specifically provides a palletizing device for processing bagged cement. Background Technology

[0002] Bagged cement is a commonly used building material in the construction industry. After packaging, it needs to be neatly stacked on pallets using palletizing equipment for storage and transportation. Currently, the industry generally uses high-level palletizers or robotic palletizing equipment to automatically palletize bagged cement. These devices typically consist of a conveying mechanism, a bag pressing and shaping mechanism, a grouping and pushing mechanism, a clamping and gripping mechanism, a lifting and palletizing mechanism, and a control system. They can realize the conveying, shaping, grouping, gripping, and layer-by-layer stacking of cement bags.

[0003] Patent CN 114644210 B discloses a palletizing device for bagged cement processing, belonging to the field of bagged cement palletizing technology. The device includes a processing platform and a palletizing apparatus. The processing platform is placed horizontally on the ground, and the palletizing apparatus is located on top of the processing platform. The palletizing apparatus includes a feeding component, a conveying component, a leveling component, a dust cover, a conveyor belt, and a palletizing frame. The dust cover is fixedly installed on top of the processing platform. The feeding component and the conveying component are both located on top of the processing platform. The conveyor belt and the leveling component are both located on top of the feeding component. The palletizing frame is located on top of the processing platform. This invention, by conveying and moving the bagged cement using the palletizing apparatus, shakes off dust from the outer surface of the bagged cement, thus preventing dust dispersion during palletizing and isolating the dust on the surface of the bagged cement within the dust cover.

[0004] This application improves the palletizing equipment used for cement processing. When the palletizing device transports and moves the bagged cement, it can shake off the dust on the outer surface of the bagged cement, thus preventing dust dispersion during palletizing. The dust on the surface of the bagged cement is isolated inside the dustproof box. However, after the surface dust is shaken off, cement dust inside the cement bag will still come out from the gaps in the cement bag during the palletizing process. At the same time, the cement bags are prone to breaking, falling out, or not being clamped securely when clamping. Furthermore, there is no positioning of the pallet during palletizing, which will lead to skewed stacks, uneven stacks, and inconsistent layer heights. Therefore, we propose a palletizing equipment for bagged cement processing. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a clamping mechanism to clamp the cement bag body on the surface of the first conveyor belt and place it above the stacking pallet for stacking bagged cement. After the cement bag body is conveyed to the clamping position above the first conveyor belt, the rotating device is moved above the cement bag body by a folding rod. The set limiting baffle first limits the cement bag body and straightens it. When the clamping mechanism moves downward, the set limiting baffle is pushed upward under the action of the clamping mechanism moving downward. When the limiting baffle moves to the top, it is pulled and flipped onto the upper surface of the sliding plate by the pull of the tie rod. At the same time, the push spring is compressed. When the cement bag is lowered, the limiting baffle is first pushed forward by the push of the push spring, and then pushed downward by the push of the positioning and fixing rod. Thus, the cement bag body can continue to be limited before clamping the cement bag body. The hydraulic pull rod pulls the pulling rod and clamping rod towards the center, clamping the cement bag body. Simultaneously, as the pulling rod moves inward, it pushes the second toothed rod inward, which in turn drives the transmission gear to rotate. When the transmission gear rotates, it pulls the first toothed rod and the sliding support plate inward. The sliding support plate, moving to the bottom of the cement bag body, protects it from falling during clamping and conveying. A dust-collecting baffle collects dust generated during clamping. As the clamping rod moves towards the center, the rotating wheel slides on the upper surface of the first conveyor belt, and the sliding plate lifts both sides of the cement bag body. The clamping rod inserts below the cement bag body. During clamping, the sliding plate lifts both sides of the cement bag body, preventing scratches on the surface of the cement bag body when clamping it.

[0017] 2. This invention uses a dust-proof limiting mechanism to limit the position of the pallet and remove floating dust during the palletizing of bagged cement. When the pallet is conveyed by the second conveyor belt, it moves in front of the positioning limiting plate and is blocked by the positioning limiting plate. At the same time, the side limiting plates on both sides limit the pallet on both sides, thereby conveying the pallet to a fixed position. When the bagged cement is palletized by the clamping mechanism, the dust generated is extracted through the dust suction port. Then, the dust suction motor is started and the dust is extracted into the dust collection box through the dust suction pipe and connecting pipe for filtration and collection.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous 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 therefore the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-10The palletizing equipment for processing bagged cement shown includes a main support frame 1, a cement bag body 5, a first conveying frame 6, a second conveying frame 8, and a palletizing tray 16. A transverse support frame 12 is fixedly connected to the upper surface of the main support frame 1. A flattening mechanism 2 for compacting and flattening the cement bag body 5 is provided inside the main support frame 1. A clamping mechanism 3 for clamping and conveying the cement bag body 5 is provided above the main support frame 1. A dustproof limiting mechanism 4 for limiting the palletizing tray 16 and collecting the generated dust is provided on the left side of the main support frame 1.

[0023] The clamping mechanism 3 includes a movable plate 301 slidably connected to the upper surface of the transverse support frame 12. A control motor 302 is fixedly connected to the upper surface of the movable plate 301. A folding rod 303 is rotatably connected to the lower surface of the movable plate 301. A rotating device 304 is rotatably connected to the bottom end of the folding rod 303. A fixed base plate 305 is fixedly connected to the bottom end of the rotating device 304. A sliding groove 306 is provided inside the fixed base plate 305. A hydraulic pull rod 307 is fixedly connected to the upper surface of the fixed base plate 305. Pulling rods 308 are fixedly connected to both ends of the hydraulic pull rod 307. A clamping rod 309 is fixedly connected to the lower surface of the pulling rod 308. A rotating wheel 310 is rotatably connected to the bottom end of the clamping rod 309. A fixed top plate 311 is fixedly connected to the inside of the clamping rod 309. A second telescopic rod 312 is fixedly connected to one side of the fixed top plate 311. A telescopic spring 313 is sleeved on the outer surface of the second telescopic rod 312. A sliding plate 314 is sleeved on the outer surface of the bottom end of the second telescopic rod 312. The clamping rod 309 is slidably connected to the inside of the slide groove 306. The sliding plate 314 is slidably connected to the upper surface of the clamping rod 309. The fixed top plate 311 and the sliding plate 314 are fixedly connected through the second telescopic rod 312. The two clamping rods 309 are connected by a hydraulic pull rod 307.

[0024] Furthermore, a clamping mechanism is used to clamp the cement bag body on the surface of the first conveyor belt and place it above the stacking pallet for stacking the bagged cement. After the cement bag body on the first conveyor belt is transported to the clamping position, the rotating device is moved above the cement bag body by the folding rod. The limiting baffle 324 serves to first limit the cement bag body 5 and simultaneously straighten it. When the clamping mechanism 3 moves downward, the limiting baffle 324 is pushed upward under the action of the clamping mechanism 3 moving downward. When the limiting baffle 324 moves to the top, it is pulled and flipped onto the upper surface of the sliding plate 314 by the pull of the tie 326. At the same time, the push spring 328 is compressed. When the cement bag is lowered, the limiting baffle 324 is first pushed forward by the push of the push spring 328, and then pushed downward by the push of the positioning and fixing rod 330. Thus, the cement bag body 5 can continue to be clamped before being placed. The system first limits the movement of the cement bag, then uses a hydraulic lever to pull the pulling rod and clamping rod towards the center. The clamping rod then clamps the cement bag body. Simultaneously, when the pulling rod 308 moves inward, it pushes the second toothed rod 322 inward, which in turn drives the transmission gear 318 to rotate. When the transmission gear 318 rotates, it pulls the first toothed rod 319 and the sliding support plate 315 inward. The sliding support plate 315 moves to the bottom of the cement bag body 5 to protect it and prevent it from falling during clamping and conveying. The dust suction baffle 323 collects the dust generated during clamping and placement. As the clamping rod moves towards the center, the rotating wheel slides on the upper surface of the first conveyor belt. The sliding plate drags the two sides of the cement bag body up, and the clamping rod inserts below the cement bag body. During the clamping process, the sliding plate lifts the two sides of the cement bag body, thus preventing the surface of the cement bag body from being scratched when clamping it.

[0025] The dustproof limiting mechanism 4 includes a second lifting frame 401 slidably connected inside the main support frame 1. A lifting outer frame 402 is fixedly connected to one side of the second lifting frame 401. A dust suction port 403 is provided inside the lifting outer frame 402. A dust suction pipe 404 is fixedly connected to the side surface of the lifting outer frame 402. A dust suction chamber 405 is fixedly connected to the other side of the second lifting frame 401. A vacuum motor 406 is fixedly connected inside the vacuum chamber 405. An air outlet pipe 407 is fixedly connected to one side of the vacuum motor 406.

A limit spring 412 is sleeved on the outer surface of the third telescopic rod 411. A position positioning limit plate 413 is fixedly connected to one end of the third telescopic rod 411. A side limit plate 414 is rotatably connected to the side surface of the second fixing plate 410. An internal limiting groove 416 is provided. Connecting rods 415 are fixedly connected to both ends of the position positioning limiting plate 413. The dust suction pipe 404 and the dust suction chamber 405 are connected through a connecting pipe 409. The dust collection box 408 is located below the air outlet pipe 407. The dust collection box 408 has filter screen material on both sides. Ventilation openings are provided on both sides of the dust suction chamber 405. The limiting spring 412 is located between the position positioning limiting plate 413 and the second fixed plate 410. The position positioning limiting plate 413 and the second fixed plate 410 are fixedly connected through a third telescopic rod 411. The connecting rod 415 is slidably connected inside the limiting groove 416. The side limiting plates 414 are located on both sides of the palletizing pallet 16.

[0026] Furthermore, the dustproof limiting mechanism 4 is used to limit the pallet 16 and remove floating dust when palletizing bagged cement. When the pallet 16 is conveyed by the second conveyor belt 11, it moves in front of the position positioning limiting plate 413 and is blocked by the position positioning limiting plate 413. At the same time, the side limiting plates 414 on both sides limit the pallet 16 on both sides, so that the pallet 16 can be conveyed to a fixed position. When the bagged cement is palletized by the clamping mechanism 3, the generated dust is extracted through the dust suction port 403. Then, the dust suction motor 406 is started and the dust is extracted into the dust collection box 408 through the dust suction pipe 404 and the connecting pipe 409 for dust filtration and collection.

[0027] The flattening mechanism 2 includes a flattening fixing rod 201 fixedly connected inside the main support frame 1. A first fixing plate 202 is fixedly connected to one side of the flattening fixing rod 201. A threaded rod 203 is threadedly connected inside the first fixing plate 202. A limit block 205 is slidably connected inside the first fixing plate 202. A first lifting frame 204 is fixedly connected to one side of the limit block 205. A first telescopic rod 206 is fixedly connected to the bottom end of the first lifting frame 204. A flattening spring 207 is sleeved on the outer surface of the first telescopic rod 206. A fixing frame 208 is fixedly connected to the bottom end of the first telescopic rod 206. A rotating roller 209 is rotatably connected inside the fixing frame 208. The threaded rod 203 is rotatably connected to the upper surface of the first lifting frame 204. The fixing frame 208 and the first lifting frame 204 are connected in series. 04 is fixedly connected by the first telescopic rod 206, the rotating roller shaft 209 is set above the cement bag body 5, the first conveyor frame 6 is internally connected to the first conveyor belt 7, the second conveyor frame 8 is internally rotatably connected to the first conveyor shaft 9 and the second conveyor shaft 14, the outer surface of the first conveyor shaft 9 is fixedly connected to the first conveyor wheel 10, the outer surface of the first conveyor wheel 10 is internally connected to the second conveyor belt 11, the outer surface of the second conveyor shaft 14 is fixedly connected to the second conveyor wheel 15, the side surface of the second conveyor frame 8 is fixedly connected to the conveyor motor 13, the second conveyor wheel 15 and the first conveyor wheel 10 are connected by the second conveyor belt 11, the second conveyor shaft 14 is fixedly connected to the output shaft of the conveyor motor 13, and the pallet 16 is placed above the second conveyor belt 11.

[0028] Furthermore, during the conveying of the cement bag body 5, the set flattening mechanism 2 is used to flatten and compact the cement bag body 5. When the cement bag body 5 passes under the rotating roller shaft 209, the upper surface of the cement bag body 5 is flattened and compacted by the rotating limit block 205, thereby preventing the phenomenon of skewed stacking, stacking deviation, and uneven layer height during the subsequent stacking process.

[0029] Working principle: First, the cement bag body 5 is conveyed to the palletizing equipment's gripping position via the first conveyor belt 7. During conveying, the cement bag body 5 is flattened and compacted by the flattening mechanism 2. When the cement bag body 5 passes below the rotating roller 209, the rotating limit block 205 flattens and compacts the upper surface of the cement bag body 5, thus preventing uneven stacking, misalignment, and inconsistent layer heights during subsequent palletizing. After reaching the gripping position, the rotating device 304 is moved above the cement bag body 5 via the folding rod 303. The limiting baffle 324 serves to first limit the position of the cement bag body 5 and simultaneously straighten it. When the clamping mechanism 3 moves downward, the limiting baffle 324 is pushed upward by the downward movement of the clamping mechanism 3. When the limiting baffle 324 reaches its uppermost position, it is pulled and flipped onto the upper surface of the sliding plate 314 by the pull of the tie rod 326, while the push spring 328 is compressed. When the cement bag is lowered, the limiting baffle 324 is first pushed forward by the push spring 328, and then pushed by the positioning and fixing rod 330. 324 is pushed downwards, thus continuing to limit the cement bag body 5 before clamping it. Then, the hydraulic pull rod 307 pulls the pulling rod 308 and the clamping rod 309 towards the center, clamping the cement bag body 5 through the clamping rod 309. Simultaneously, when the pulling rod 308 moves inwards, it pushes the second toothed rod 322 inwards, which in turn drives the transmission gear 318 to rotate. When the transmission gear 318 rotates, it pulls the first toothed rod 319 and the sliding support plate 315 inwards, moving them to the cement bag body through the sliding support plate 315. The bottom of 5 can protect the cement bag body 5 to prevent it from falling during clamping and conveying. The dust suction baffle 323 set during clamping and placement collects the generated dust. When the clamping rod 309 moves to the middle, the rotating wheel 310 slides on the upper surface of the first conveyor belt 7. The sliding plate 314 drags the two sides of the cement bag body 5 to lift up. The clamping rod 309 is inserted under the cement bag body 5. During the clamping process, the sliding plate 314 lifts the two sides of the cement bag body 5, thereby preventing the surface of the cement bag body 5 from being scratched when clamping the cement bag body 5.After the cement bags 5 are fully stacked on the pallet 16, the empty pallet 16 is transported by the second conveyor belt 11. When the pallet 16 is transported by the second conveyor belt 11, it moves in front of the positioning limit plate 413 and is blocked by the plate. Simultaneously, the side limit plates 414 on both sides limit the pallet 16, thus transporting it to a fixed position. When the bagged cement is stacked by the clamping mechanism 3, the generated dust is extracted through the suction port 403. Then, the suction motor 406 is activated, and the dust is extracted through the suction pipe 404 and connecting pipe 409 into the dust collection box 408 for filtration and collection.
