[0050] Ton-bag materials are often unloaded manually by hanging and unpacking them, a cumbersome and unsafe process. The bags must be opened and the contents emptied. Manual unpacking is inefficient and produces dust and fine impurities that are harmful to the human body. Furthermore, contaminants may adhere to the bag surface during transportation, posing a risk of contamination during unpacking. To address these issues, fully automatic unpacking machines have emerged to replace manual unpacking.
[0051] The present application provides a fully automatic bag unpacking machine, which aims to solve the problem that dust and fine impurities harmful to the human body are easily generated during the unpacking of ton bags, and there is a risk of contaminating materials.
[0052] As shown in Figures 1, 2, 3, 8, 10 and 17, in one embodiment of the present application, the fully automatic unpacking machine 100 includes a conveying device 1, a transfer and clamping device 3, a ton bag grabbing device 4 and a bag breaking device 5. The conveying device 1 is used to convey ton bags; the transfer and clamping device 3 includes a lower frame 31, a first drive mechanism 33 and two clamping slides 32. The lower frame 31 forms a conveying channel 371, and the conveying channel 371 has a first station and a second station. The two clamping slides 32 are arranged opposite to each other and are located on both sides of the conveying channel 371. The first station is docked with the conveying device 1. The first drive mechanism 33 is used to drive the two transfer and clamping devices 3 to transport the ton bags located at the first station to the second station; the ton bag grabbing device 4 includes a track mechanism, a second drive mechanism 420 and a grabbing mechanism. The bag-breaking device 5 comprises a discharge hopper 51 and a bag-breaking tool 52. The discharge hopper 51 has a discharge bin 511 and an inlet 512 and an outlet 513 which are connected to and opposite to the discharge bin 511. The bag-breaking tool 52 is arranged in the discharge bin 511, and the blade of the bag-breaking tool 52 is arranged upward. The second drive mechanism 420 is used to drive the grabbing mechanism to grab the ton bag located at the second station and move it to above the inlet 512. The grabbing mechanism is also used to move the ton bag down to contact with the bag-breaking tool 52.
[0053] In this embodiment, the conveyor device 1 is docked with external equipment to transport ton bags of material to the rear-end equipment. The ton bag is moved to the first station. At this point, the two transfer and clamping devices 3 approach each other to grip the ton bag and lift it off the first station. The first drive mechanism 33 moves the transfer and clamping devices 3 and the ton bag above the second station, where the two transfer and clamping devices 3 place the ton bag. A gripping mechanism grabs the ton bag at the second station. The second drive mechanism 420 moves on a track, driving the gripping mechanism and the ton bag above the feed port. The gripping mechanism lowers the ton bag, causing the bag-breaking tool 52 to pierce the bottom of the ton bag, creating an opening. The material in the ton bag flows through the bottom opening into the discharge bin 511 and out through the discharge port 513, completing a bag-breaking and unloading cycle. The entire bag-breaking and unloading process requires no human assistance, and the working environment poses no health risks to workers.
[0054] It can be understood that in this application, the next ton bag is not transported after completing a bag breaking and unloading cycle. Instead, when the ton bag moves from the first station to the second station, the conveying mechanism 1 conveys the next ton bag to the first station, thereby ensuring the continuous supply of materials and reducing waiting time.
[0055] In one embodiment, the fully automatic bag unpacking machine 100 further includes an air shower 2, mounted above the conveyor 1. Air shower 2 is used to clean contaminants from the surface of the ton bags. When the ton bags reach the air shower 2, the air shower 2 sweeps away contaminants from the bags, ensuring a clean surface for the bags destined for subsequent processes.
[0056] Air shower device 2 consists of hatch A, hatch B, a flexible rolling shutter, an air shower clamp, a lifting cylinder, a fan, an air duct, and air holes. The main function of the air shower device is to clean contaminants attached to the surface of the ton bag. The main operation is that the ton bag is transported from hatch A into the air shower chamber by a roller line. After reaching the predetermined position, the flexible rolling shutter of hatch A of the air shower chamber closes, the clamp picks up the ton bag, and the lifting cylinder lifts the clamp and the ton bag together. The air generated by the fan is blown into the air duct and air holes, sweeping away contaminants attached to the surface of the ton bag. A dust removal port is opened at the bottom of the air shower chamber, and the purged fly ash and dust are discharged from the cabin through the dust removal port. After the purge is completed, the clamp returns the ton bag to the pallet, and the flexible rolling shutter of hatch B opens. After the ton bag enters the next workstation, hatch B closes and hatch A opens, preparing for the next ton bag to enter the air shower chamber. The conveying device can be a roller line.
[0057] In other embodiments, the surface of the ton bag material can also be cleaned and pretreated by external equipment. The conveying device 1 transports the ton bags that have completed the cleaning and pretreatment, thereby ensuring that the surface of the ton bags flowing to the subsequent process is clean, thereby avoiding contamination of the material.
[0058] In one embodiment of the present application, as shown in Figures 3 to 7, the transfer and clamping device 3 includes a lower frame 31, a first drive mechanism 33 and two clamping slides 32. The lower frame 31 includes two first guide beams 311 spaced apart along a first direction, a transport channel 371 is formed between the two first guide beams 311, and the transport channel 371 has a first station and a second station spaced apart along a second direction; the two clamping slides 32 are arranged in a one-to-one correspondence with the two first guide beams 311; each clamping slide 32 includes a support frame 321, a first drive assembly 322, a second drive assembly 323 and a clamping fixture 324, and the support frame 321 is connected to the corresponding first guide beam 311 is a sliding connection; the first drive component 322 is connected to the support frame 321, and the output end of the first drive component 322 is connected to the second drive component 323; the output end of the second drive component 323 is connected to the clamping fixture 324; the first drive component 322 is used to drive the second drive component 323 and the clamping fixture 324 to move in the vertical direction, and the second drive component 323 is used to drive the clamping fixture 324 to move in the first direction; the first drive mechanism 33 is transmission-connected to the two support frames 321, and the first drive mechanism 33 is used to drive the two support frames 321 to move synchronously in the second direction; wherein the first direction, the second direction and the vertical direction are perpendicular to each other.
[0059] In this embodiment, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. A clamping slide 32 is provided on each side of the conveying channel 371. The first drive assembly 322, the second drive assembly 323, and the first drive mechanism 33 enable movement in three directions (X, Y, and Z). This allows for clamping, lifting, transferring, unclamping, and resetting of the ton bag material.
[0060] Among them, the second drive component 323 pushes the clamping fixture 324 back and forth to clamp and release the ton bag, and the first drive component 322 drives the second drive component 323 and the clamping fixture 324 to move up and down in the vertical direction to realize the up and down lifting of the clamped ton bag; both sides can be lifted and lowered at the same time, the clamping effect is more stable, and the deflection of the ton bag after it is in place is effectively prevented; the first drive mechanism 33 synchronously drives the left and right clamping slides 32 to move forward or backward horizontally synchronously. The synchronous movement can effectively avoid the problem of misalignment of the clamping slide 32 during movement caused by different moving distances or speeds, thereby damaging the ton bag or causing the ton bag material to fall off.
[0061] When the ton bag is transported to the first workstation, the two clamping slides 32 are located on both sides of the first workstation, and the second drive assembly 323 drives the corresponding clamping fixture 324 to move so that the two clamping fixtures 324 move relative to each other until the ton bag is clamped; after the clamping fixture 324 moves into place, the first drive assembly 322 drives the second drive assembly 323 and drives the clamping fixture 324 and the clamped ton bag to move upward. When the ton bag is suspended in the air, the first drive mechanism 33 drives the entire clamping slide 32 and the clamped ton bag to move forward to the top of the second workstation; at this time, the first drive assembly 322 drives the second drive assembly 323 and drives the clamping fixture 324 and the clamped ton bag to move downward until the ton bag falls into place (there is a supporting platform at the second workstation, and the ton bag falls into place when it contacts the supporting platform); then the second drive assembly 323 drives the two clamping fixtures 324 to release the ton bag. Thus, the transport of the ton bag is completed once, and then the clamping fixture 324 moves to both sides of the first workstation under the action of the first drive component 322, the second drive component 323 and the first drive mechanism 33 to transport the ton bag again.
[0062] In one embodiment, the transfer and clamping device 3 further includes a roller line 372, which has a first station. The preceding equipment conveys the ton bag onto the roller line 372 (the ton bag is placed on a pallet 373 and is transported along with the pallet 373). The roller line 372 can be equipped with a sensor switch. When the sensor switch senses that the ton bag is in place, the roller line 372 stops. A mechanical limit plate can also be provided on the roller line 372. After the sensor switch senses that the ton bag material is in place, when the clamping slides 32 on both sides are at the corresponding roller line 372 positions, the second drive head assembly pushes the clamping fixture 324 to clamp the ton bag material on the roller line 372. After checking that the clamping is in place, the vertical lifting cylinder of the first drive assembly 322 performs a lifting action to lift the ton bag off the pallet 373. After confirming that the lifting is in place, the first drive mechanism 33 drives the clamping slide 32 to transfer it to the second station. After confirming that it is in place, the lifting cylinder of the clamping slide 32 lowers to its position, and the second drive assembly 323 drives the clamping fixture 324 to retract and release the material. When the clamping slide 32 is completely out of the first station, the lifting mechanism of the roller line 372 rises and transfers the empty pallet 373 out of the roller line 372 station. After the sensor detects that the pallet 373 has completely left the roller line 372, the lifting mechanism of the roller line 372 returns to its original position, ready to receive the next pallet 373 and ton bag material. After the clamping slide 32 confirms that the clamping and unloading are completed, the clamping slide 32 returns to the roller line 372 station and resets to the initial state to prepare for clamping the next ton bag of material.
[0063] In other embodiments, the roller line may also be the output structure of the previous device, and the previous device is connected to the transfer and clamping device 3 in this application through the roller line.
[0064] In one embodiment, the first drive assembly 322 includes a first drive member, and the second drive assembly 323 includes a mounting bracket 3231 and a second drive member 3232. The output end of the first drive member is connected to the mounting bracket 3231, and the second drive member 3232 is mounted on the mounting bracket 3231. The output end of the second drive member 3232 is connected to the clamping fixture 324. The first and second drive members 3232 are connected by the mounting bracket 3231, which provides a mounting location for the second drive assembly 3233 and improves the connection strength. The mounting bracket 3231 is slidably connected to the support frame 321, thereby limiting the movement direction of the mounting bracket 3231 and improving the stability of the first drive member driving the second drive member 3232 and the clamping fixture 324.
[0065] In the first example of the aforementioned embodiment, the output end of the first drive member is connected to the mounting bracket 3231 via a floating joint 341. Because the movement direction of the first drive member is determined by the mounting position, the movement direction of the mounting bracket 3231 is also determined. Due to installation errors, when the movement direction of the output rod of the first drive member deviates from the movement direction of the mounting bracket 3231, the floating joint 341 can absorb the tolerance, ensuring that the first drive member can drive the mounting bracket 3231 to move smoothly. The floating joint 341 is a standard hardware component; it only needs to connect one end of the floating joint 341 to the output end of the first drive member and the other end to the mounting bracket 3231. The specific structure of the floating joint 341 is not described in this application.
[0066] In the second example of the above-described embodiment, the mounting frame 3231 is slidably connected to the support frame 321 via a guide rail slider mechanism 342; the guide rail slider mechanism 342 enables the sliding connection between the mounting frame 3231 and the support frame 321. The support frame 321 is provided with two guide rails, which extend vertically and are spaced apart in the front-to-back direction. The mounting frame 3231 is provided with at least two sliders, which are slidably connected to the two guide rails in a one-to-one correspondence. In one embodiment, the mounting frame 3231 may be provided with four sliders, with two sliders corresponding to each guide rail, to further improve stability during the sliding process.
[0067] In the third example of the above embodiment, similar to the above second embodiment, the clamping fixture 324 and the mounting frame 3231 are slidably connected via the guide rail slider mechanism 342 .
[0068] The first, second, and third examples described above can be implemented individually or in any combination. Of course, the mounting frame 3231 and the support frame 321 can also be guided and slid by linear bearings and guide rods; the clamping fixture 324 and the mounting frame 3231 can also be guided and slid by linear bearings and guide rods.
[0069] Mounting frame 3231 includes a top plate, a bottom plate, and two side plates. The top and bottom plates are spaced vertically apart, and the two side plates are connected between the bottom and top plates. A floating joint 341 is provided on the bottom plate, and the clamping fixture 324 is slidably connected to the bottom plate. Mounting frame 3231 also includes two connecting plates, each connected to the two side plates. Sliders are provided on the connecting plates to slidably connect to the guide rails on the support frame 321. Reinforcement plates can also be provided between the connecting plates and the side plates to further enhance the strength of the entire mounting frame 3231. Mounting frame 3231 also includes a baffle. One end of the second driving member 3232 is connected to the clamping fixture 324, and the other end is connected to the baffle. The extension or retraction of the second driving member 3232 drives the clamping fixture 324 to slide left and right on the bottom plate.
[0070] In one embodiment, a first roller 3251 and a second roller assembly are disposed at the bottom of the support frame 321. The first roller 3251 is in rolling contact with the top surface of the first guide beam 311. The second roller assembly includes two oppositely positioned second rollers 3252, which are in one-to-one rolling contact with opposite side walls of the first guide beam 311. The contact between the first rollers 3251 and the top surface of the first mounting beam converts sliding friction into rolling friction, reducing wear and increasing the service life of the transfer and clamping device 3. The two second rollers 3252 not only assist in sliding but also serve as limit guides to prevent the slide assembly from tilting.
[0071] In one embodiment, the transfer and clamping device 3 further includes an upper frame 35 spaced apart from the lower frame 31 in the height direction. The upper frame 35 includes two second guide beams 351 spaced apart along the first direction. The tops of the two support frames 321 are slidably connected to the two second guide beams 351 in a one-to-one correspondence. Specifically, the upper and lower ends of the support frames 321 are slidably connected to the upper frame 35 and the lower frame 31, respectively, and the support frames 321 can be limited in the left and right directions, thereby ensuring a more stable process of the first drive mechanism 33 driving the clamping slide 32.
[0072] A first roller 3251 and a second roller group can also be set on the top of the support frame 321. The first roller 3251 is in rolling contact with the bottom surface of the second guide beam 351. The second roller group includes two oppositely arranged second rollers 3252. The two second rollers 3252 are in rolling contact with the opposite side walls of the second guide beam 351 in a one-to-one manner.
[0073] In one embodiment, the first drive mechanism 33 includes a third drive member 331, a transmission chain 332, and two driven wheels 333. The two driven wheels 333 are spaced apart on the first guide beam 311 and rotatably connected to the first guide beam 311. The transmission chain 332 is wound around the outer periphery of the two driven wheels 333. The third drive member 331 drives the transmission chain 332 to rotate about the two driven wheels 333. The support frame 321 is connected to the transmission chain 332. The third drive member 331 drives the support frame 321 through the transmission chain 332, thereby driving the clamping slide 32. Chain drive eliminates elastic slip and slippage, resulting in a precise average transmission ratio, reliable operation, and high efficiency. It also features high power transmission, strong overload capacity, and compact transmission dimensions under the same operating conditions. It also requires low tension and exerts low pressure on the shaft. It can operate in harsh environments such as high temperature, humidity, dust, and pollution. It is well suited for applications where the combined weight of the clamping slide 32 and the ton bag is heavy.
[0074] In one embodiment, the first drive mechanism 33 further includes a synchronization shaft 334. Each of the two first guide beams 311 has a driven wheel 333 connected to the synchronization shaft 334. By using the synchronization shaft 334, a third drive member 331 can be used to simultaneously drive two transmission chains 332, thereby driving the movement of the two clamping slides 32. In this embodiment, the third drive member 331 is provided on the right side for illustration. The third drive member 331 directly drives the transmission chain 332 on the right side to move. During the movement of the transmission chain 332, the two driven wheels 333 are synchronously driven, thereby driving the synchronization shaft 334 to rotate. In one embodiment, the transmission shaft drives the driven wheel 333 on the left side to rotate, thereby driving the clamping slide 32 to move via the transmission chain 332.
[0075] Among them, the driven wheel 333 and the synchronization shaft 334 can be connected by key connection or bolt fastening, so that torque can be transmitted between the driven wheel 333 and the synchronization shaft 334, so that the transmission chains 332 on the left and right sides can rotate synchronously, thereby driving the clamping slides 32 on the left and right sides to move synchronously.
[0076] In other embodiments, the two transmission chains 332 on the left and right sides may also be respectively provided with a corresponding third driving member 331. One third driving member 331 drives the corresponding clamping slide 32 to move, thereby reducing the load on the third driving member 331.
[0077] In this application, the first drive member can be a pneumatic cylinder, the second drive member 3232 can be a pneumatic cylinder, and the third drive member 331 can be a motor. Using a motor for the second drive member 3232 allows for adjusting the clamping force of the clamping fixture 324 on the ton bag by adjusting the driving air pressure. In other embodiments, the first drive mechanism 33 can be a screw-nut transmission mechanism.
[0078] In one embodiment, the transfer and clamping device 3 further includes a protective cover 361, which is connected to the edge of the support frame 321. The support frames 321 form an installation space between the support frames 321, and the first drive assembly 322 and the second drive assembly 323 are located within the installation space. The protective cover 361 fully encloses the entire transmission structure of the clamping slide 32 (the first drive assembly 322 and the second drive assembly 323), preventing the transmission mechanism from being exposed and accumulating dust, which could affect the transmission effect, or the risk of fasteners on the transmission structure falling off and entering the material.
[0079] Protective covers 361 are provided on both sides of the support frame 321. The protective covers 361 are designed to accommodate the entire travel range of the first drive assembly 322. A flexible sheath 363 can be provided between the clamping fixture 324 and the support frame 321 to accommodate the travel range of the second drive assembly 323. When the second drive assembly 323 drives the clamping fixture 324 to retract, the flexible sheath 363 can fold and deform to avoid interference with the ton bag.
[0080] In one embodiment, an accordion cover 364 may be provided outside the transmission chain 332 to protect the transmission chain 332. The accordion cover 364 is divided into two sections, and the two sections of the accordion cover 364 are respectively connected to the front and rear ends of the clamping slide 32.
[0081] In one embodiment, one side of the protective cover 361 is rotatably connected to the support frame 321, and the other side of the protective cover 361 is connected to the support frame 321 via a buckle 362. That is, in this application, by unlocking the buckle 362, the protective cover 361 can be rotated to expose the internal transmission structure, which is convenient for inspection and maintenance.
[0082] In one embodiment of the present application, the clamping fixture 324 includes a base 3241 and at least two clamping rods 3242; at least two clamping rods 3242 are arranged on the base 3241 at intervals along the height direction, and each clamping rod 3242 has a clamping rod 32421 that is concave inward in the first direction, and each clamping rod 3242 forms a clamping surface on the side facing away from the base 3241, and the clamping surface of the clamping rod 3242 located on the lower side protrudes from the clamping surface of the clamping rod 3242 located on the upper side.
[0083] The clamping fixture 324 is driven by a drive assembly, and typically requires two opposing clamping fixtures 324 to clamp and transport the ton bag. In this embodiment, two clamping rods 3242 are used. These two clamping rods 3242 are spaced apart in height, and each clamping rod 3242 forms a clamping rod 32421. The concave structure of the clamping rod 32421 adapts to the bulge on the side of the ton bag, increasing the clamping contact area. Furthermore, the clamping surface of the lower clamping rod 3242 is slightly more convex than that of the upper clamping rod 3242, creating a V-shaped clamp between the ton bag and the clamping fixture 324, which enhances the clamping effect. This ensures effective clamping, regardless of whether the ton bag is packed with loose or compacted materials, with a high success rate and stable clamping during transport.
[0084] In addition, the middle of the clamping rod 3242 is concave, which is conducive to automatic centering after clamping when the position of the ton bag is offset relative to the transfer and clamping device 3, and effectively solves the problem of large eccentric load force after the clamping is lifted due to material offset; it makes the structure life longer, and the ton bag is not easy to be damaged due to excessive force on the eccentric load side caused by eccentric load.
[0085] In this embodiment, more clamping rods 3242 may be provided in the clamping fixture 324 , for example, 3, 4, or 5. This embodiment does not limit the number of the clamping rods 3242 .
[0086] In other embodiments, the transfer clamping device 3 can also be composed of a base and a clamping plate assembly, with the lower end of the clamping plate protruding toward the transport channel 371, thereby forming a V-shaped clamp when the two clamping plates cooperate to clamp the ton bag; the middle part of the clamping plate is concave inward in the direction away from the transport channel 371, thereby adapting to the bulging shape of the side of the ton bag and increasing the contact area of the clamping.
[0087] In one embodiment, the clamping fixture 324 further includes an abutment surface 32432 located behind the clamping surface, and its shape matches that of the clamping rod 32421. When the ton bag is deformed by the clamp, once the deformation reaches a certain level, the ton bag forms a low-pair contact with the abutment surface 32432, effectively controlling the ton bag's insertion depth and preventing damage. This also facilitates unloading during unclamping, preventing the ton bag from becoming lodged in the gap between the two clamping rods 3242.
[0088] In the first embodiment described above, the clamping fixture 324 further includes a shield plate 3243, which is disposed over the connection side between the base 3241 and the clamping rod 3242. The shield plate 3243 is provided with an abutting section 32431 corresponding to the clamping rod 32421, and the abutting section 32431 forms an abutting surface 32432. At least the clamping surface of the clamping rod 3242 is exposed to the shield plate 3243. In other words, the abutting surface 32432 is formed by the shield plate 3243. The shield plate 3243 is connected to the base 3241, and a through hole is formed in the shield plate 3243 for the clamping rod 3242 to pass through, thereby facilitating the connection between the clamping rod 3242 and the base 3241.
[0089] In other examples, the base 3241 may have a complete mounting surface, and the clamping rod 3242 is connected to the mounting surface. In this case, the mounting surface can serve as the abutment surface 32432.
[0090] Based on the above example, the top edge and the two opposite sides of the shield plate 3243 are connected with folding plates 3244, which are arranged at an angle. That is, the top of the shield plate 3243 adopts a bevel structure, which facilitates clamping and loosening and prevents damage to the ton bag caused by right-angle contact.
[0091] When the width of the passport plate is greater than the length of the clamping rod 3242, both sides of the shield plate 3243 are also set to be inclined structures, so as to avoid damage to the ton bag during the process of the clamping fixture 324 moving toward the ton bag.
[0092] Of course, the top of the shield plate 3243 can also be a curved surface, as long as the shield plate 3243 does not have sharp edges facing upwards to avoid damage to the ton bags.
[0093] In one embodiment, the base 3241 includes a mounting base 32411 and multiple connecting ribs 32412. The multiple connecting ribs 32412 are spaced along the length of the clamping rod 3242, and the clamping rod 3242 is fixedly connected to the multiple connecting ribs 32412. Specifically, the base 3241 is formed by splicing the top of the shield plate 3243. The multiple connecting ribs 32412 increase the number of connection points with the clamping rod 3242, ensuring overall connection strength. Furthermore, compared to a monolithic base 3241, this structure significantly reduces the overall weight of the clamping fixture 324.
[0094] In order to further reduce the overall weight of the clamp, weight-reducing holes can be opened on the mounting base plate 32411 and the connecting rib plate 32412 .
[0095] A strip hole is provided on the mounting base 32411, and a connecting protrusion is provided on the connecting rib 32412. By snapping the connecting protrusion into the strip hole, the installation position of the connecting rib 32412 can be limited. Then, the connecting rib 32412 and the mounting base 32411 are fixed together by welding or bolting, thereby ensuring the installation position accuracy of the connecting rib 32412 and ensuring that multiple connecting ribs 32412 can match the curvature of the clamping rod 3242.
[0096] Based on the above embodiment, the connecting ribs 32412 are provided with connecting grooves 32413, and the clamping rods 3242 are sequentially inserted into the connecting grooves 32413 on each connecting rib 32412. The provision of the connecting grooves 32413 on the connecting ribs 32412 increases the contact area between the clamping rods 3242 and the connecting ribs 32412, thereby further improving the connection strength.
[0097] The ends of the clamping rod 3242 are concave inward in the first direction to form an avoidance section. The ends of the clamping rod 3242 are bent backward, which facilitates the ton bag to enter the middle of the left and right clamps after the clamping clamp 324 is retracted, and prevents the ton bag from being damaged when the ends are squeezed in after the clamps are clamped;
[0098] The clamping rod 3242 and the base 3241 can be welded; the welded structure has strong overall integrity, high rigidity and high strength.
[0099] The clamping rod 3242 may be a hollow rod. To improve safety, sealing plates 3245 are provided at both ends of the clamping rod 3242 to prevent sharp edges from being formed at the ends of the clamping rod 3242 .
[0100] The base 3241 is provided with a mounting hole 32414 for a fastener to pass through for connection with an external drive assembly.
[0101] The clamping surface of the clamping rod 3242 is curved, creating a high-pitch contact between the clamping rod 3242 and the ton bag. This allows the clamping fixture 324 to easily squeeze and deform the ton bag, creating a sufficient support surface to support the ton bag's contents, especially for denser packaging. This effectively reduces the impact of the clamping fixture 324 on the ton bag. The clamping rod 3242 is formed from a bent circular tube, with the diameter of the upper clamping rod 3242 being smaller than that of the outer clamping rod 3242. The use of a large and a small arc column structure, used in pairs, creates a V-shaped clamping pattern during contact, enhancing the clamping effect.
[0102] In one embodiment, as shown in Figures 8 and 9, the ton bag grabbing device 4 includes a track mechanism, a second drive mechanism 420 and a grabbing mechanism, the grabbing mechanism includes a bracket 412, a bag shaking assembly 450, and a grabbing assembly 430, the second drive mechanism 420 is movably set on the track mechanism; the bracket 412 is set on the second drive mechanism 420, and the second drive mechanism 420 is used to drive the bracket 412 to move along a first direction, and the first direction is parallel to the extension direction of the track mechanism; the bag shaking assembly 450 is set on the bracket 412; the grabbing assembly 430 can be raised and lowered on the bag shaking assembly 450; the second drive mechanism 420 drives the bracket 412 to move to the loading station, the grabbing assembly 430 descends to grab the ton bag, and the grabbing assembly 430 rises to lift the ton bag; or the second drive mechanism 420 drives the bracket 412 to move to the unloading station, and the grabbing assembly 430 descends to release the ton bag.
[0103] Different workstations can be set along the path of the track mechanism, for example, a loading station is set at the starting end of the track mechanism, an unloading station is set at the end of the track mechanism, and other functional stations are set between the loading station and the unloading station.
[0104] The second drive mechanism 420 drives the carriage 412 along the track mechanism. When passing a loading station, the gripper assembly 430 grabs a ton bag from the loading station. The second drive mechanism 420 then drives the carriage 412 to move to other stations for further operations, ultimately driving it to the unloading station for unloading. When passing an unloading station, the bag shaking assembly 450 drives the gripper assembly 430 to shake, thereby discharging as much material as possible from the ton bag.
[0105] By integrating the bag shaking assembly 450 and the grabbing assembly 430 on the bracket 412, the footprint of the equipment is reduced.
[0106] This technical solution utilizes a shaking mechanism and a grabbing assembly 430 mounted on a bracket 412. The grabbing assembly 430 is used to grab the ton bag. After grabbing the ton bag, the second drive mechanism 420 transfers the ton bag. Once the ton bag reaches a designated location, the shaking mechanism shakes the material out. The overall structure is compact, highly integrated, and saves equipment floor space. The entire operation process is highly automated, improving production efficiency and reducing manual intervention.
[0107] In one embodiment, the track mechanism includes two guide rails 411 arranged opposite and in parallel; the second driving mechanism 420 includes a driver 421 and two transmission components 422, and the driver 421 is arranged on the bracket 412; the two transmission components 422 are arranged on both sides of the bracket 412 at intervals along the first direction, and the two transmission components 422 are both connected to the driver 421, and the two ends of the two transmission components 422 are respectively connected to the two guide rails 411.
[0108] The guide rail 411 is a linear guide rail 411. In view of different application scenarios, the guide rail 411 can be set as an arc guide rail 411 according to different environments to drive the bracket 412 to move in different directions.
[0109] During assembly, the two ends of the transmission assembly 422 are placed on the guide rails 411 on both sides. The two guide rails 411 support the two ends of the transmission assembly 422 to ensure the stability of the transmission assembly 422 and the bracket 412 during movement.
[0110] The driver 421 can be implemented in different ways, such as a motor, a cylinder, etc., to drive the bracket 412 to move.
[0111] As an embodiment, the transmission assembly 422 includes a main pulley 4223, a connecting shaft 4222 and two mounting plates 4221, the two mounting plates 4221 are arranged on both sides of the bracket 412 at intervals along the second direction, and the second direction is perpendicular to the first direction; the connecting shaft 4222 is passed through the two mounting plates 4221; a main pulley 4223 is provided at each end of the connecting shaft 4222, the rotating shaft of the main pulley 4223 is overlapped with the rotating shaft of the connecting shaft 4222, and the two main pulleys 4223 are respectively connected to the top surfaces of the two guide rails 411 in a rolling manner.
[0112] In this embodiment, the bracket 412 is rectangular or square. The direction of bracket 412 movement is defined as the front-to-back direction, with the side toward the feeding station being the front direction, also known as the first direction, and the side toward the feeding station being the rear direction. Furthermore, the direction perpendicular to the movement of bracket 412 is defined as the left-to-right direction, also known as the second direction.
[0113] To further enhance the stability of the bracket 412 during movement, two sets of transmission assemblies 422 are employed. Each transmission assembly 422 includes two main pulleys 4223, for a total of four main pulleys 4223. After the transmission assemblies 422 are installed, a main pulley 4223 is provided on each of the left and right edges of the bracket 412 in the front-to-back direction.
[0114] The two main pulleys 4223 on the left and right sides are connected by a connecting shaft 4222. When the driver 421 drives the connecting shaft 4222 to rotate, it can drive the two main pulleys 4223 on the left and right sides to rotate synchronously. This ensures that the movement speed of both sides of the bracket 412 is consistent, preventing the bracket 412 from deflecting during movement and ensuring the stability of the equipment operation.
[0115] As another embodiment, the driver 421 is driven by a motor 4211. A main gear 4212 is mounted on the output shaft of the motor 4211, and an auxiliary gear 4213 is provided on the connecting shafts 4222 on the front and rear sides of the bracket 412. The main gear 4212 and the two auxiliary gears 4213 are aligned in the first direction. A gear chain is simultaneously mounted on the three gears, and the gear chain is kept taut, thereby linking the three gears.
[0116] When the output shaft of the motor 4211 rotates, it can drive the front and rear connecting shafts 4222 to rotate synchronously at the same time, thereby ensuring that the speeds of the front and rear sides of the bracket 412 are consistent, further improving the stability of the overall structure during operation.
[0117] It should be noted that the motor 4211 can be installed in the front direction of the two connecting shafts 4222, in the rear direction of the two connecting shafts 4222, or between the two connecting shafts 4222. In the case of only one gear chain, the motor 4211 can be installed in the front direction of the two connecting shafts 4222 or in the rear direction of the two connecting shafts 4222 to ensure that the main gear 4212 can be stably connected to the gear chain.
[0118] As another embodiment, in order to prevent the gear in the middle position of the gear chain from being unable to be reliably connected to the gear chain, two main gears 4212 can be installed on the output shaft of the motor 4211.
[0119] Each auxiliary gear 4213 is in the same straight line with a main gear 4212 in the first direction, and two gear chains are set in total. Each gear chain connects the main gear 4212 and the auxiliary gear 4213 on the same straight line, so that when the output shaft of the motor 4211 rotates, the two connecting shafts 4222 can also rotate synchronously and maintain the consistency of the rotation frequency of the two connecting shafts 4222.
[0120] It can be understood that in this embodiment, the motor 4211 is installed between the two connecting shafts 4222, thereby saving the length of the gear chain, while also improving the compactness of the overall structure and reducing the floor space.
[0121] In one embodiment, the second driving mechanism 420 further includes a sliding assembly 423 , one end of which is disposed on a side wall of an edge of the bracket 412 , and the other end of the sliding assembly 423 is connected to a side surface of the guide rail 411 .
[0122] During the movement of the bracket 412 , in order to prevent contact and friction between the side walls of the bracket 412 and the guide rail 411 , sliding components 423 are further provided on the left and right side walls of the bracket 412 .
[0123] The left and right sliding assemblies 423 are connected to the two guide rails 411 respectively, which play a role in limiting the position of the bracket 412, preventing the side walls of the bracket from contacting and causing friction with the guide rails 411. At the same time, the sliding assemblies 423 can improve the flexibility of the bracket 412 during the sliding process. For example, it can play a role in assisting turning when dealing with curved tracks.
[0124] Specifically, the sliding assembly 423 includes a pulley bracket 4231 and an auxiliary pulley 4232. The pulley bracket 4231 is arranged on the side wall of the edge of the bracket 412; the auxiliary pulley 4232 is arranged on the pulley bracket 4231, and the auxiliary pulley 4232 is rollingly connected to the side of the guide rail 411, wherein the rotating axis of the auxiliary pulley 4232 is perpendicular to the rotation of the main pulley 4223.
[0125] The sliding bracket serves as a support member for the auxiliary pulley 4232 and can be fixed to the side wall of the bracket 412 by pins.
[0126] Auxiliary pulley 4232 is connected to the sliding bracket by a rotating shaft. The rotating shaft of auxiliary pulley 4232 is perpendicular to the rotating shaft of main pulley 4223, that is, main pulley 4223 slides on the top of guide rail 411, and auxiliary pulley 4232 slides on the side (left or right) of guide rail 411.
[0127] The guide rail 411 may be a quadrangular prism structure, with one edge facing the top and one edge facing the side. A groove is formed between the primary pulley 4223 and the secondary pulley 4232, and the groove is engaged with the edge of the guide rail 411, thereby limiting the pulleys and preventing them from shifting during movement.
[0128] In one embodiment, the grabbing assembly 430 includes a lifting member 431, a support frame 432, a pin arm 433 and a grabbing pin, the lifting member 431 is arranged at the top of the bracket 412; the support frame 432 is arranged at the bottom of the bracket 412, and the lifting member 431 is connected to the support frame 432; the bag shaking assembly 450 is arranged on the support frame 432, and the pin arm 433 is connected to the bag shaking assembly 450; the pin is arranged on the pin arm 433, and the pin arm 433 is used to drive the grabbing pin to be inserted into the ton bag to grab the ton bag.
[0129] The lifting member 431 can be driven by a cylinder to achieve a lifting effect.
[0130] In order to meet the rationality of the structural design, a supporting frame 432 is installed at the bottom of the bracket 412, and a pin arm 433 is installed at the bottom of the supporting frame 432 to facilitate grabbing the ton bag at the bottom.
[0131] During grabbing, the pin arm 433 drives the grabbing pin to be inserted into the ton bag to achieve connection with the ton bag. After the connection is completed, the ton bag is lifted by the lifting member 431 to achieve the grabbing effect.
[0132] In one embodiment, the grab assembly 430 further includes a plurality of hooks 440, which are disposed around the support frame 432. If the grab assembly 430 fails, the handles of the ton bag can be manually hung on the hooks 440 to ensure that production can continue normally.
[0133] The number of hooks 440 can be adjusted according to the size of the ton bag, for example, a hook 440 can be provided on each side of the support frame 432, or a hook 440 can be provided on each side of the support frame 432.
[0134] In one embodiment, the shaking bag assembly 450 includes a connecting sleeve 451, a connecting rod 452, and a buffer. The connecting sleeve 451 is set on the bracket 412; the connecting rod 452 is set in the connecting sleeve 451, and the bottom of the connecting rod 452 extends out of the connecting sleeve 451 and is connected to the grabbing assembly 430; the buffer is set in the connecting sleeve 451, one end of the buffer is connected to the inner wall of the connecting sleeve 451, and the other end is connected to the connecting rod 452.
[0135] The connecting sleeve 451 as a supporting structure can be welded or fixed to the bracket 412 by pins.
[0136] The connecting rod 452 passes through the connecting sleeve 451 and is connected to the buffer member in the connecting sleeve 451. The buffer member can be a spring.
[0137] The bottom of the connecting rod 452 is connected to the grabbing assembly, so that when shaking, the buffer member provides a rebound force to make the connecting rod 452 shake up and down, and drive the grabbing assembly 430 to shake up and down synchronously, thereby achieving a simulated shaking effect.
[0138] In one embodiment of the present application, as shown in Figures 10 to 12, the bag breaking device 5 includes a discharge hopper 51 and a bag breaking tool 52. The discharge hopper 51 has a discharge bin 511 and an inlet 512 and an outlet 513 that are connected to and opposite to the discharge bin 511. The discharge bin 511 includes a dust removal section 5111 and a blanking section 5112 that are sequentially arranged from the inlet 512 to the outlet 513. The blanking section 5112 is gradually arranged in a direction close to the outlet 513. A dust removal port 514 is provided on the side wall of the dust removal section 5111. The dust removal port 514 is used to connect with an external air source to form a negative pressure at the dust removal port 514. The bag breaking tool 52 is arranged in the discharge bin 511, and the blade of the bag breaking tool 52 is arranged toward the inlet 512.
[0139] In the above embodiment, the ton bag is moved to the top of the bag breaking device 5 and facing the feed port 512 by an external handling device, and falls to the bag breaking knife by a mechanical structure or the action of the ton bag's own gravity. The blade of the bag breaking knife 52 faces upward, and the bag breaking knife 52 can be inserted into the ton bag from the bottom of the ton bag, thereby forming an opening on the ton bag, so that the material in the ton bag falls from the opening into the blanking section 5112. During the blanking process, since the central area is blocked by the ton bag, dust can only escape from the gap between the ton bag and the inner wall of the unloading bin 511. This application provides a dust removal port 514 on the dust removal section 5111 above the blanking section 5112, and forms a negative pressure at the dust removal port 514 to perform dust removal operations, thereby preventing dust materials from escaping and polluting other parts of the equipment when the ton bag is broken and blanked.
[0140] Among them, the blanking section 5112 has a funnel-shaped structure that can play a role in diversion and concentration, and the dust removal port 514 can be connected to an external recovery system. The dust can be recovered by the recovery system and put into use again, thereby improving material utilization.
[0141] In one embodiment, the discharge bin 511 further includes an inlet section 5113 located at the end of the dust removal section 5111 away from the material discharge section 5112. The wall of the dust removal section 5111 is vertically arranged, and the inlet section 5113 is tapered toward the material discharge section 5112. Because the ton bag is flexible, increasing the downward movement distance of the ton bag can cause the ton bag to deform and rest on the inlet section 5113, reducing the escape of dust and material. Furthermore, the inner wall of the inlet section 5113 is inclined, with the entire inlet section 5113 having a wide top and narrow bottom structure. This prevents sharp edges from damaging the ton bag and increases the surface area between the ton bag and the inner wall of the inlet section 5113.
[0142] In one embodiment, the bag-breaking device 5 further includes a dust removal assembly 53, which includes a housing 531 and a duct 532. The edge of the housing 531 is connected to the discharge hopper 51 to form a negative pressure chamber 533 that communicates with the dust removal port 514. The duct 532 is connected to the housing 531 to connect the negative pressure chamber 533 with an external air source. The negative pressure chamber 533 provides a pressure equalization effect, making the negative pressure at the dust removal port 514 uniform, thereby ensuring better dust removal.
[0143] In one embodiment, the bottom wall of the negative pressure chamber 533 is tilted downward in a direction close to the dust removal port 514, and the lower edge of the bottom wall of the negative pressure chamber 533 is flush with the lower edge of the dust removal port 514. Dust in the negative pressure chamber 533 may adhere to the inner wall of the negative pressure chamber 533. By configuring the bottom wall as an inclined structure, dust materials adsorbed by the dust removal port 514 can be accumulated on the bottom wall and then slide down the bottom wall to the blanking section 5112 for recycling. The lower edge of the bottom wall of the negative pressure chamber 533 is flush with the lower edge of the dust removal port 514, which can avoid the formation of a step surface at the edge of the dust removal port 514 to block the accumulated dust materials, thereby partially recovering the dusted materials and reducing the material loss rate.
[0144] The housing 531 also includes a dust suction port connected to the negative pressure chamber 533, located on the same side as the duct 532. The dust removal assembly 53 also includes a cover plate 535, which is used to cover the dust suction port to block it. At regular intervals or when the negative pressure at the dust removal port 514 decreases, the cover plate 535 can be removed to open the dust suction port and clean the negative pressure chamber 533. The dust suction port and cover plate 535 facilitate subsequent cleaning and maintenance.
[0145] There can be multiple dust removal ports 514, which are spaced apart circumferentially along the inner wall of the dust removal section 5111. Each dust removal port 514 is provided with a corresponding dust removal assembly 53, thereby better ensuring that the dust removal negative pressure at each location is uniform and ensuring the dust removal effect.
[0146] In other embodiments, multiple dust removal ports 514 can share one negative pressure chamber 533 to reduce structural complexity.
[0147] In one embodiment, the bag breaking device 5 further includes a plurality of support bases 55, each of which is connected to the outer wall of the discharge hopper 51. The plurality of support bases 55 cooperate to secure the discharge hopper 51. The support bases 55 are connected to the bottom surface or the mounting platform, thereby securing the discharge hopper 51 and ensuring stability during the bag breaking and unloading process.
[0148] Based on the above embodiment, a weighing sensor 557 is provided on the support base 55. Since the discharge hopper 51 is supported by the support base 55, when a ton bag falls into the cutting hopper, the weight of the entire discharge hopper 51 increases significantly. When the weighing sensor 557 detects a significant increase in weight, the dust removal negative pressure is turned on. Therefore, the negative pressure can be turned off when not in use or between transports, saving energy.
[0149] In one embodiment, when the weighing sensor 557 senses that the material in the ton bag is basically unloaded, the ton bag can be shaken and swung if it has a mechanical structure to hang it, so as to shake out the material in the ton bag more thoroughly and minimize the residual material in the bag.
[0150] In one embodiment, the cross-section of the dust removal section 5111 is square, and the blanking section 5112 includes four connecting surfaces 51121, and the upper edges of the four connecting surfaces 51121 are connected to the four sides of the dust removal section 5111 in a one-to-one correspondence; the blanking section 5112 also includes a transition surface 51122, and any two adjacent connecting surfaces 51121 are connected by the transition surface 51122, and the lower edges of the four transition surfaces 51122 are connected in sequence to form a discharge port 513. In this application, by setting the transition surface 51122, the angle between the two adjacent connecting surfaces 51121 is converted into the angle between the two sides of the transition surface 51122 and the two connecting surfaces 51121. Obviously, the angle formed between the transition surface 51122 and the connecting surface 51121 is larger, thereby avoiding the accumulation of dust materials at the angle.
[0151] In other embodiments, the cross-section of the dust removal section 5111 may also be circular, and correspondingly, the cross-section of the discharge section 5112 may also be circular, so that the inner wall surface of the entire unloading bin 511 does not have an angular structure, and the material can slide out smoothly along the inner wall surface of the unloading bin 511.
[0152] In one embodiment of the present application, the bag breaking device 5 includes a discharge hopper 51, a bag breaking tool 52 and a plurality of fixed components 54. The discharge hopper 51 has a discharge bin 511 and an inlet 512 and an outlet 513 that are connected to and opposite to the discharge bin 511; the bag breaking tool 52 is arranged in the discharge bin 511, and the blade of the bag breaking tool 52 is set upward; a plurality of fixed components 54 are arranged at intervals along the outer periphery of the discharge hopper 51, and each fixed component 54 includes a pin drive 541 and a fixed pin 542. The fixed pin 542 can slide through the side wall of the discharge port, and the output end of the pin drive 541 is connected to the fixed pin 542. The pin drive 541 is used to drive the fixed pin 542 to extend into the discharge bin 511 and retract.
[0153] In this embodiment, the ton bag grabbing device carries the ton bag to the top of the bag-breaking device 5, facing the feed inlet 512. The ton bag then drops to the bag-breaking cutter 52, either mechanically or by its own gravity. With the blade of the bag-breaking cutter 52 facing upward, the cutter can penetrate the ton bag from the bottom, creating an opening in the bag, allowing the material inside to fall through the opening into the material-discharging section. When the ton bag contacts the bag-breaking cutter 52, the pin driver 541 extends the fixed pins 542, which then insert into the bottom of the ton bag to stabilize it. This secures the bottom of the bag and the opening, allowing for more thorough removal of the material inside and minimizing residual material. Furthermore, the opening remains fixed during unloading, preventing material spillage and reducing dust. After unloading is complete, the fixed pins 542 are withdrawn. This application utilizes the bottom fixed pins 542 to secure the ton bag, while the top bag-grabbing mechanism rises and falls to assist in unloading. This minimizes residual material in the waste bag, effectively improving customer efficiency.
[0154] The bag-breaking device 5 uses a weighing sensor 58 to detect whether the ton bag has been lowered into place. Similarly, the weighing sensor 58 can also detect whether the material in the ton bag has been discharged. When the ton bag is punctured by the bag-breaking tool 52 and contacts the wall of the discharge bin 511, the weight of the entire discharge hopper 51 will increase significantly. However, when the material in the ton bag has been discharged, the weight of the entire discharge hopper 51 will tend to a fixed value. Therefore, the change in the value detected by the weighing sensor 58 can be used to generate a signal for the pin driver 541 to drive the fixed pin 542 to extend or retract.
[0155] In other embodiments, detection may be performed through a distance sensor, a camera, etc., and a signal may be sent to cause the pin driving member 541 to drive the fixed pin 542 to extend or retract.
[0156] In one embodiment, the fixing assembly 54 further includes a guide sleeve 543 and a piston rod 544 disposed within the sleeve. The sleeve is connected to the discharge hopper 51, and the sleeve is slidably connected to the fixing pin 542. Specifically, the fixing pin 542 uses the guide sleeve 543 and the piston rod 544 to determine its movement trajectory, thereby ensuring smooth sliding of the fixing pin 542 and ensuring its effective fixation of the ton bag.
[0157] Based on the above embodiment, the fixing assembly 54 also includes a baffle 545, which is positioned transversely within the sliding sleeve, near the end of the sliding sleeve facing away from the discharge hopper 51. The sliding sleeve is positioned between the baffle 545 and the outer wall of the discharge hopper 51. The baffle 545 defines a through-hole 52111, into which the fixing pin 542 fits. The gap between the fixing pin 542 and the through-hole 52111 is very small, so when the fixing pin 542 is retracted, it remains partially inserted into the through-hole 52111, thereby preventing the powdered material from escaping.
[0158] In one embodiment, the bag-breaking device 5 further includes support bases 55, the number of which matches the number of fixing assemblies 54. The support bases 55 have support arms 551 connected to the sidewalls of the discharge hopper 51. Pin drivers 541 are disposed on the support bases 55 in a one-to-one correspondence. The support bases 55 are connected to the ground or mounting platform to secure the discharge hopper 51, thereby securing the entire bag-breaking device 5. The pin drivers 541 are disposed on corresponding support bases 55, enabling the support bases 55 to serve multiple purposes.
[0159] Two support arms 551 are provided on a support seat 55, and the two support arms 551 are arranged at intervals; a mounting platform 552 is formed between the two support arms 551, and the two support arms 551 are both connected to the outer wall of the discharge hopper 51, and the pin drive component 541 is installed on the mounting platform 552.
[0160] The pin drive member 541 can be a pneumatic cylinder, with a fixed plate connected to the piston rod of the cylinder. The end of the fixed pin 542 away from the needle tip is connected to the fixed plate, specifically by bolts. Thus, the cylinder drives the fixed pin 542 to move, and the cylinder and the fixed pin 542 are not on the same horizontal plane, but are connected by the fixed plate. This allows the cylinder's piston rod 544 to extend away from the discharge hopper 51, thereby driving the fixed pin 542 to retract. That is, the cylinder's extension drives the fixed pin 542 to retract, and the cylinder's retraction drives the fixed pin 542 to extend, thereby making more effective use of the installation space.
[0161] The weighing sensor 58 is also arranged on the support base 55. It can be understood that the support base 55 serves as a structure supporting the entire bag breaking device 5. The weight changes in the discharge hopper 51 can be immediately and accurately sensed by the weighing sensor 58 installed on the support base 55.
[0162] In one embodiment, the discharge hopper 51 is formed by splicing together multiple side panels. The number of fixing assemblies 54 matches the number of side panels and is arranged in a one-to-one correspondence. For example, if the discharge bin 511 has a square cross-section, the discharge hopper 51 has four side panels, and the corresponding number of fixing assemblies 54 is also four. The fixing pins 542 of the four fixing assemblies 54 are inserted into four positions of the ton bag, further ensuring that the bottom outlet is positioned correctly when the ton bag is discharged.
[0163] In other embodiments, the cross-sectional shape of the discharge hopper 51 may also be circular, and a plurality of fixing components 54 may be arranged at intervals along the circumference to fix the ton bags as required.
[0164] In one embodiment, the bag breaking device 5 further comprises an air hammer 56 which is fixedly mounted on the outer wall of the discharge hopper 51. During the material unloading process, air vibration devices are arranged around the bag breaking device 5 to assist the material in unloading smoothly and prevent the material from accumulating on the side wall of the discharge bin 511.
[0165] In one embodiment of the present application, as shown in Figures 13 to 16, the bag breaking tool 52 includes a tool seat 521 and a tool body 522; the tool body 522 is connected to the tool seat 521, and a notch 5221 is provided on one side of the tool body 522. The tool body 522 has at least three blade tops 5222 protruding in a direction away from the tool seat 521, and a blade bottom 5223 is provided at both ends of the tool and between any two blade tops 5222, which is concave in a direction close to the tool seat 521. A continuous blade 5224 is provided between the blade bottom 5223 and the adjacent blade top 5222.
[0166] The bag breaking tool 52 is applied to the bag breaking device 5 as shown in Figure 10. In this embodiment, in actual application, the bag breaking tool 52 is moved by a mechanical structure or the ton bag is transported by a mechanical structure to the top of the bag breaking tool 52 and falls to the bag breaking tool 52 under the action of the gravity of the ton bag. The bag breaking tool 52 is inserted into the ton bag from the bottom of the ton bag. Since there is a notch 5221 on one side of the tool body 522, that is, a part of the tool does not have a blade 5224, a C-shaped structure is formed. Part of the punctured hole of the ton bag is still connected to the ton bag and will not fall in and mix with the material. In addition, the blade top 5222 of the bag breaking tool 52 is not less than 3 points, and the 3 points support a plane. The blade top 5222 is inserted into the ton bag and supports it, so that the ton bag is not easy to deflect, and the ton bag is prevented from deflecting to form a dead zone of material accumulation, which is convenient for bag breaking and material dropping; the wavy arc blade 5224 is formed by the alternating blade top 5222 structure and the blade bottom 5223 structure, which is continuous and has no notches. When the bag is broken, it is not easy for the bottom of the ton bag to be fuzzy or produce foreign matter.
[0167] It can be understood that since the entire cutter body 522 has blade bottoms 5223 at both ends, the number of blade tops 5222 is N, and the number of blade bottoms 5223 is N+1. In actual use, the number of blade tops 5222 and blade bottoms 5223 can be greater, for example, the number of blade tops 5222 can be 4, 5, 6, etc. When the volume of a ton bag is large, increasing the number of blade tops 5222 can make it more convenient to break the bag and support the ton bag. This application does not limit the number of blade bottoms 5223.
[0168] The tool body 522 includes a plurality of blade groups 5225 connected in sequence, each blade group 5225 including a left blade 52251 and left and right blades 52252 symmetrically arranged. In a blade group 5225, the connection between the left blade 52251 and the left and right blades 52252 forms a blade top 5222; the connection between the left blade 52251 of a blade group 5225 and the left and right blades 52252 in the adjacent blade group 5225 forms a blade bottom 5223. That is, the tool body 522 is formed by a plurality of identical units (blade groups 5225) arranged in sequence, and the two blades of the same unit (left blade 52251 and left and right blades 52252) are symmetrical structures. Therefore, when the bag breaking tool 52 acts on the ton bag, it can ensure that the forces on the bottom 5223 of each blade tend to be consistent, further ensuring that the effects of each blade on the ton bag tend to be consistent, and at the same time maintaining the cutting effect of the bottom 5223 of the blade, ensuring the success rate of bag breaking, and making the entire bag breaking process start from the top 5222 of the blade, cutting the ton bag along the blade 5224 to the bottom 5223 of the blade, thereby ensuring the smoothness of the entire ton bag breaking operation and the stability and consistency of the bag breaking effect.
[0169] In one embodiment, the cutter body 522 projects onto the cutter holder 521 as an arc-shaped structure with a central angle of 270° to 350°. Specifically, the cutter body 522 is a monolithic C-shaped cutter, rolled integrally. This creates a generally circular opening in the ton bag, while retaining a certain connection to prevent the bag from falling into and mixing with the material. Furthermore, the generally circular opening lacks a corner structure, preventing the corner from tearing under stress and further expanding the opening. This ensures the structural stability of the ton bag opening, providing a clear location for the material to be dropped.
[0170] In other embodiments, the tool body 522 may be formed by splicing multiple single structures; or the tool body 522 may be formed by splicing multiple blade segments. This application does not limit whether the tool body 522 is a single piece or a spliced piece.
[0171] The blade holder 521 includes a base 5211 and a support member 5212. The positions of the cutter body 522 corresponding to the blade bottom 5223 are all connected to the base 5211 via the support member 5212. At least one position of the cutter body 522 corresponding to the blade top 5222 is also connected to the base 5211 via the support member 5212. The provision of the support member 5212 increases the number of connection points between the cutter body 522 and the blade holder 521, thereby increasing the strength of the connection. Furthermore, a certain distance is maintained between the blade bottom 5223 and the base 5211 of the cutter holder 521, allowing the entire cutter body 522 to extend into the ton bag, thereby ensuring that the airflow holes 5226 in the cutter body 522 have a fluidizing effect on the material.
[0172] In one embodiment, the cutter body 522 is provided with an air hole 5226. The air hole 5226 is connected to an external air source. When the bag breaking cutter 52 is inserted into the ton bag, the air hole 5226 can continuously ventilate the material to fluidize the material and improve the efficiency of the discharge.
[0173] In other embodiments, the base 5211 may be provided with air holes 5226, and the support 5212 may also be removable. This increases the number of air holes 5226 and further improves the fluidization efficiency of the material within the ton bag. The air holes 5226 disposed on the cutter body 522, support 5212, and base 5211 inflate the ton bag, allowing any remaining material in the ton bag to fall into the discharge hopper 51.
[0174] In one embodiment, the base 5211 is provided with a through hole 52111 for communicating with an external air source; a channel 52121 is formed within the support member 5212, and the support member 5212 is further provided with an air inlet 52122 and an air outlet 52123 communicating with the channel 52121. The air inlet is connected to the through hole 52111, and the air outlet 52123 is connected to the air flow hole 5226. In other words, the support member 5212 also serves as a connecting pipe, eliminating the need for a complex piping structure within the bag breaking device 5 and ensuring smooth material flow after the bag breaking device 5 opens the ton bag.
[0175] In one embodiment, a limiting notch 52124 is defined at the top of the support member 5212, and the air outlet 52123 is formed on the sidewall of the limiting notch 52124. The bottom wall of the limiting notch 52124 of the support member 5212 cooperates to support the tool body 522, and the tool body 522 contacts the sidewalls of each limiting notch 52124. The limiting notch 52124 serves as a limiter during installation of the tool body 522. The combination of the limiting notches 52124 on the support member 5212 can substantially secure the installation position of the tool body 522, thereby facilitating subsequent welding to secure the tool body 522 to the support member 5212. This allows the tool body 522 to be positioned prior to welding, ensuring that the air outlet 52123 aligns with the airflow hole 5226 after welding. Furthermore, the welded connection ensures a tight seal at the ends of the support member 5212.
[0176] In one embodiment, the top of the support member 5212 has two connected guide surfaces 52125. These guide surfaces 52125 are tilted downward, away from the limiting notch 52124. The junction of the two guide surfaces 52125 is coplanar with the blade top 5222 or blade bottom 5223. This means that the top of the support member 5212 has no sharp edges, preventing damage to the ton bag. Furthermore, the tilted top surface of the support member 5212 allows the material to slide down the guide surfaces 52125 during outflow, preventing accumulation.
[0177] In one embodiment, multiple blanking gaps are formed between the cutter body 522 and the cutter seat 521. The support member 5212 divides the gap between the cutter body 522 and the seat 5211 into multiple second blanking gaps 5232. The seat 5211 is annular, and the hollow portion of the seat 5211 forms the first blanking gap 5231. That is, after being opened by the bag-breaking cutter 52, the ton bag can fall directly through the first blanking gap 5231, or it can first pass through the second blanking gap 5232 and then enter the first blanking gap 5231, thereby improving blanking efficiency.
[0178] The base body 5211 can be connected to the discharge hopper 51 through a flange; in other embodiments, the base body 5211 can also be connected to the discharge hopper 51 through a triangular connecting plate 571, and the bag breaking tool 52 is set up in the discharge hopper 51 through four triangular connecting plates 571, thereby raising the position of the bag breaking tool 52, thereby increasing the depth of the bag breaking tool 52 inserted into the ton bag. Due to the overhead design, after the bag breaking tool 52 is inserted into the ton bag mouth, the material can fall through the gap more smoothly.
[0179] An air passage connected to the through hole 52111 is provided on the triangular connecting plate 571 , and the air passage is connected to an external air source, and a regulating valve 572 is provided on the connected pipe, so that the negative pressure at the dust removal port 514 can be conveniently adjusted.
[0180] In one embodiment, as shown in Figures 17 to 21, the bag squeezing device 6 includes a recovery frame 61, a swinging assembly 62, a first telescopic assembly 63 and a second telescopic assembly 64. The recovery frame 61 includes a shell, the shell includes a cavity 612, the cavity 612 is formed with a first opening and a second opening 611, the first telescopic assembly 63 is telescopically arranged in a horizontal direction, the swinging assembly 62 is installed on the shell, and the second telescopic assembly 64 is installed on the swinging assembly 62. The swinging assembly 62 can drive the second telescopic assembly 64 to extend into or retract from the cavity 612 toward the second opening 611, and the first telescopic assembly 63 can extend into or retract from the cavity 612 toward the first opening. When it is time to recycle a ton bag, the operator picks up the ton bag and drops it into the cavity 612 from the second opening 611. At this point, the bag squeezing device 6 is activated, and the swing assembly 62 drives the second telescopic assembly 64 toward the second opening 611. Once in position, the second telescopic assembly 64 extends toward the second opening 611 and into the inner cavity, squeezing the ton bag into the inner cavity for the first time. The second telescopic assembly 64 then retracts, and the first telescopic assembly 63 extends horizontally to squeeze the ton bag for the second time. Finally, the first telescopic assembly 63 retracts, and the above actions are repeated. Generally speaking, the swing assembly 62 and the first telescopic assembly 63 move back and forth 2 to 5 times to meet the squeezing requirements. After squeezing the ton bag to a certain size, the swing assembly 62 drives the second telescopic assembly 64 away from the second opening 611 and back to its original position. At this point, the next ton bag can be dropped in for squeezing. The above scheme simulates the folding of the waste ton bags by squeezing the waste ton bags from two directions, which is conducive to the ton bags entering the extrusion cavity 612, compressing the ton bags to the maximum extent, reducing the volume of the ton bags, and maximizing the use of the extrusion space. The number of extrusions of the ton bags can be set by setting the number of movements of the first telescopic component 63 and the swing component 62, thereby setting the size of the ton bags after extrusion.
[0181] In one embodiment, a transport device can be connected to the second opening 611, and the transport device can transport the ton bag to the second opening 611, so that there is no need to manually put the ton bag into the bag squeezing device 6. Furthermore, a control component and a detector can be set, and the detector is set at the second opening 611. The control component is respectively connected to the detector, the transport device, the swing component 62, the first telescopic component 63 and the second telescopic component 64 by signal. In this way, when the detector detects that there is a ton bag at the second opening 611, it sends a signal to the control component, and the control component controls the transport device to stop moving. When the squeezing is completed, the transport component resumes movement.
[0182] In one embodiment, the housing includes a baffle 613 and a bottom plate 614 connected perpendicularly to each other. A first opening is provided on the side of the cavity 612, opposite the baffle 613, and a second opening 611 is provided at the top of the cavity 612, opposite the bottom plate 614. The first and second openings 611 are arranged perpendicularly to each other, and the first and second telescopic assemblies 63 and 64 extend and retract perpendicularly to each other, thereby further enhancing the squeezing effect. By squeezing the ton bag multiple times in the vertical and horizontal directions, the ton bag can be squeezed to a certain size, further reducing the area occupied by the ton bag collection.
[0183] In one embodiment, the baffle 613 is detachable. When the ton bag inside is full, the baffle 613 can be removed, the ton bag inside can be moved out, and then the baffle 613 can be installed again until the ton bag is full next time.
[0184] The first telescopic assembly 63 includes a first frame 631 and a first telescopic cylinder 632. The first frame 631 is mounted on the side of the recovery frame 61 near the first opening. The first telescopic cylinder 632 is mounted on the first frame 631. The extension shaft of the first telescopic cylinder 632 can extend into or retract from the cavity 612 toward the first opening. When extrusion is required, the extension shaft of the first telescopic cylinder 632 is controlled to extend, squeezing the ton bag with the extension shaft of the first telescopic cylinder 632, causing the ton bag to be compressed and squeezed. After the extrusion is completed, the extension shaft of the first telescopic cylinder 632 is retracted. The ton bag is squeezed directly by the extension shaft of the first telescopic cylinder 632, reducing the manufacturing cost of the equipment.
[0185] In one embodiment, the recycling frame 61 also includes a pressure plate 633, which is slidably installed at the first opening. The protruding shaft of the first telescopic cylinder 632 is connected to the pressure plate 633, and the protruding shaft of the first telescopic cylinder 632 can be extended to drive the pressure plate 633 to move toward the baffle 613; when extrusion is required, the protruding shaft of the first telescopic cylinder 632 is controlled to extend, and at the same time, the protruding shaft of the first telescopic cylinder 632 pushes the pressure plate 633 to move, and compresses and squeezes the ton bag to move toward the baffle 613. After the compression and extrusion is completed, the protruding shaft of the first telescopic cylinder 632 pulls the pressure plate 633 back to its original position; by setting the pressure plate 633, the ton bag can be compressed and extruded more effectively.
[0186] In one embodiment, the second telescopic assembly 64 includes an end plate 641, a second frame 642, and a second telescopic cylinder 643. The second frame 642 includes a fixed plate 6421. The extension shaft of the second telescopic cylinder 643 is connected to the end plate 641, and the cylinder body of the second telescopic cylinder 643 is connected to the fixed plate 6421. The fixed plate 6421 is provided with a through hole. The end plate 641 is provided with an extrusion rod 6411. The extrusion rod 6411 passes through the through hole, allowing the extension shaft of the second telescopic cylinder 643 to extend into or retract from the cavity 612 toward the second opening 611. After the swing assembly 62 is activated to squeeze the ton bag into the second opening 611, when the ton bag enters a certain depth and the swing assembly 62 cannot reach the ton bag, the second telescopic cylinder 643 is activated to squeeze the ton bag. When there is no ton bag that needs to be squeezed, the second telescopic cylinder 643 is in an extended state. When squeezing is required, the extension shaft of the second telescopic cylinder 643 is controlled to retract. At the same time, the extension shaft of the second telescopic cylinder 643 pulls the end plate 641 toward the fixed plate 6421. At this time, the squeezing rod 6411 passes through the through hole and moves toward the bottom plate 614. In this process, the squeezing rod 6411 compresses and squeezes the ton bag. After the compression and extrusion are completed, the extension shaft of the second telescopic cylinder 643 extends and pushes the end plate 641 back to its original position. The squeezing rod 6411 follows and returns to its original position. Then the swing assembly 62 drives the second telescopic cylinder 643 away from the second opening 611 and returns to its original position. Such a structure can realize compression and squeezing of ton bags in the vertical direction.
[0187] In one embodiment, there are multiple extrusion rods 6411, and the multiple extrusion rods 6411 are distributed on the end plate 641. There are multiple through holes, and the multiple through holes are distributed on the fixed plate 6421. The multiple extrusion rods 6411 are arranged in a one-to-one correspondence with the multiple through holes. By setting multiple extrusion rods 6411, the contact surface with the ton bag is increased, which can further improve the efficiency of compression and extrusion.
[0188] In one embodiment, a plurality of extrusion rods 6411 are evenly distributed on the end plate 641, and a plurality of through holes are evenly distributed on the fixing plate 6421. In this way, during vertical extrusion, the ton bag is subjected to more uniform force, which is conducive to improving the extrusion effect.
[0189] In one embodiment, the swing assembly 62 includes a swing cylinder 621, a rotating shaft 622, and two bearing blocks 623. The two ends of the rotating shaft 622 are rotatably mounted on the two bearing blocks 623. A connecting piece 6221 is rotatably mounted on the rotating shaft 622. One end of the connecting piece 6221 is connected to the second frame 642, and the other end of the connecting piece 6221 is connected to the swing cylinder 621. When the swing cylinder 621 begins to swing, it drives the connecting piece 6221 to rotate about the rotating shaft 622. Simultaneously, the connecting piece 6221 drives the second frame 642 to swing up and down. This arrangement allows the ton bag to be compressed and squeezed without the second telescopic cylinder 643 being fully retracted.
[0190] In one embodiment, a threaded hole is provided on the protruding shaft of the swing cylinder 621, and the bag squeezing device 6 also includes a first locking rod 65, which is installed on the connecting piece 6221, and the first locking rod 65 is installed in the threaded hole; by adjusting the angle between the swing cylinder 621 and the connecting piece 6221, the range of the up and down swinging of the second frame 642 can be adjusted, so that the magnitude of the force for squeezing the ton bag can be adjusted.
[0191] In one embodiment, the cylinder body of the swing cylinder 621 is provided with a boss, and a first mounting hole is provided on the boss. The swing assembly also includes a screw and two mounting seats arranged at intervals, and each mounting seat is provided with a second mounting hole. The screw passes through the second mounting hole and the first mounting hole in sequence to rotatably install the cylinder body of the swing cylinder 621 on the two mounting seats arranged at intervals. In this way, when the swing cylinder 621 extends the driving rotating shaft and the connecting piece 6221 rotates, the cylinder body of the swing cylinder 621 can follow the rotation to prevent the cylinder body from being damaged due to excessive force of the extending shaft of the swing cylinder 621.
[0192] In one embodiment, the fixing plate 6421 is provided with two opposing connecting members 6421a, each of which is provided with a circular hole. The bag squeezing device 6 also includes a second locking rod 67. The cylinder body of the second telescopic cylinder 643 is provided with a third rotation hole. The second locking rod 67 passes through the third rotation hole and the circular hole to lock the cylinder body of the second telescopic cylinder 643 and the connecting member 6421a. When the second telescopic cylinder 643 requires maintenance, the second locking rod 67 is removed and the cylinder body of the second telescopic cylinder 643 is separated from the connecting member 6421a. The second telescopic cylinder 643 can then be repaired or replaced with a new one. After maintenance is complete, the third rotation hole on the cylinder body of the second telescopic cylinder 643 is aligned with the circular hole provided on the connecting member 6421a, and the second locking rod 67 is then inserted into the third rotation hole and locked with the circular hole. This structure allows for quick and easy disassembly and installation of the second telescopic cylinder 643, and is simple and convenient to operate.
[0193] In one embodiment, the extension shaft of the second telescopic cylinder 643 is provided with a fourth rotation hole, and the end plate 641 is provided with an elongated hole 6412. The bag squeezing device 6 also includes a fixing rod 66 and a third locking member 68. The extension shaft of the second telescopic cylinder 643 extends out of the elongated hole 6412, and the fixing rod 66 passes through the fourth rotation hole and abuts against the end plate 641. The fixing rod 66 is provided with a mounting hole, and the third locking member 68 is installed to the end plate 641 through the mounting hole. This structure can firmly fix the extension shaft of the second telescopic cylinder 643 to the end plate 641 and is easy to remove. The provision of the elongated hole 6412 facilitates the extension shaft of the second telescopic cylinder 643 to be inserted during installation, thus facilitating subsequent installation and allowing for easy adjustment of the position of the extension shaft of the second telescopic cylinder 643. It can also accommodate extension shafts of second telescopic cylinders 643 of different sizes.
[0194] In one embodiment, the second telescopic component 64 also includes a sleeve 644, which is installed on the fixed plate 6421, and the sleeve 644 is coaxially arranged with the through hole. The extrusion rod 6411 is telescopically sleeved on the sleeve 644 and extends out of the through hole; by setting the sleeve 644, it is equivalent to adding a track to the extrusion rod 6411, which can enable the extrusion rod 6411 to maintain linear motion at all times.
[0195] In one embodiment, please refer to Figure 22, the first telescopic component includes a first telescopic component and a second telescopic component connected to each other, the first telescopic component and the second telescopic component are both telescopically arranged at the first opening along the horizontal direction, and the extension axis of the first telescopic component can move toward the first opening to extend into or retract out of the cavity; the second telescopic component can extend to drive the first telescopic component to extend toward the third opening or retract into the cavity.
[0196] When the ton bag needs to be recycled, the operator picks up the ton bag and puts it into the cavity 612 from the second opening 611. At this time, the bag squeezing device 6 is started, the second telescopic component 64 is started, and the second telescopic component 64 moves toward the second opening 611. The extended shaft of the second telescopic component 64 extends into the cavity 612 to squeeze the ton bag into the cavity 612, and the ton bag is poked into the recycling frame 61. The ton bag is squeezed for the first time, and the first-level telescopic component 631 extends horizontally to drive the first-level telescopic component 631 to move toward the cavity 612, so that the first-level telescopic component 631 squeezes the ton bag and squeezes the ton bag that has not yet recovered for the second time, and so on. Generally speaking, the swing component 62 and the first telescopic component move back and forth 2 to 5 times to meet the squeezing needs. After the ton bag is squeezed to a certain size, when the last squeezing is just completed, the first-level telescopic component 631 is extended at this time, and the first-level telescopic component 631 is now close to the baffle 613. After the extrusion is completed, the secondary telescopic component 632 extends out to push the primary telescopic component 631 to make the extruded ton bag abut against the baffle 613, and drives the baffle 613 to rotate and open. The secondary telescopic component 632 pushes the extruded ton bag to the outside of the bag squeezing device 6 for the operator to collect. Then the primary telescopic component 631 and the secondary telescopic component 632 retract at the same time, and then the second telescopic component 64 rotates back to its original position. At this time, the next ton bag can be put in for extrusion. By setting the primary telescopic component 631 and the secondary telescopic component 632, not only can the ton bag be extruded, but also the extruded ton bag can be pushed to the outside through the secondary telescopic component 632 at the last moment of the extrusion. There is no need to stop the machine for the operator to take it out manually, which improves the working efficiency, achieves the effect of automatic discharging, and protects the safety of the operator.
[0197] In one embodiment, after the squeezed ton bags inside are piled up to a certain number, the ton bags are pushed out by the first telescopic component to achieve unified collection.
