Description

Technical Field

[0001] The present invention relates to the technical field of raw material barrel feeding and conveying, and specifically relates to a cleaning, feeding and conveying device for chemical raw material barrels. Background Art

[0002] In the process of chemical production, bagged raw materials are usually stored and transported in standardized barrel containers. Currently, when loading bagged raw materials into barrel containers, a conveying device is often used. However, the traditional conveying device has a relatively single function and can only achieve a simple barrel conveying function. Most barrels are initially sealed with barrel lids, resulting in the need to additionally set up manual lid-opening and lid-closing stations in the actual production process, which not only increases the labor intensity of operators but also reduces the overall work efficiency. At the same time, existing conveying devices generally lack an automatic barrel cleaning function and cannot effectively remove residues inside the barrel, seriously affecting the storage quality of subsequent bagged raw materials. Therefore, we propose a cleaning, feeding and conveying device for chemical raw material barrels that integrates functions of automatic lid removal, barrel cleaning, precise feeding and intelligent lid closing. Summary of the Invention

[0003] The purpose of the present invention is to provide a cleaning, feeding and conveying device for chemical raw material barrels to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A cleaning, feeding and conveying device for chemical raw material barrels includes a frame, and also includes a first conveying mechanism, a second conveying mechanism, a third conveying mechanism, a flipping mechanism, a cleaning mechanism, a lid-removing mechanism, a lid-closing mechanism, a feeding mechanism and a side-pushing mechanism arranged on the frame; The first conveying mechanism is used for conveying the barrel to the flipping mechanism. The lid-removing mechanism is used for transferring the barrel lid on the first conveying mechanism to the second conveying mechanism. The flipping mechanism is used for clamping the barrel and driving it to flip to an inverted state or a normal state. The second conveying mechanism is used for conveying the barrel lid. The cleaning mechanism is used for cleaning the inside of the barrel in the inverted state. The side-pushing mechanism is used for driving the barrel to move from the first conveying mechanism to the third conveying mechanism after the barrel is cleaned and reset to the normal state. The third conveying mechanism is used for conveying the cleaned barrel. The feeding mechanism is used for putting the bagged raw materials into the barrel when the third conveying mechanism conveys the barrel to a preset position. The lid-closing mechanism is used for transferring the barrel lid on the second conveying mechanism to the barrel being fed to close the barrel.

[0005] Further improvement lies in that the lid-removing mechanism and the lid-closing mechanism have the same structure; among them, the lid-removing mechanism includes a horizontal moving device connected to the frame and located above the second conveying mechanism. A carrier is arranged at the output end of the horizontal moving device. A first telescopic device is arranged on the carrier. A negative pressure suction head for adsorbing the barrel lid is arranged at the output end of the first telescopic device.

[0006] A further improvement lies in that the flipping mechanism includes a lifting mechanism provided on the frame, a movable seat driven by the lifting mechanism to move up and down, two groups of clamping arms symmetrically provided on one side of the movable seat, a driving device one provided on the movable seat for driving the two clamping arms to approach or move away from each other, a clamping head rotatably provided on the clamping arm for contacting the outer wall of the barrel, a driving device two provided on one clamping arm for driving the corresponding clamping head to rotate, and a counterweight provided on the other clamping head for keeping the clamping head balanced.

[0007] A further improvement lies in that the first conveying mechanism is a roller conveyor, and the cleaning mechanism includes a telescopic device two provided on the frame and below adjacent rollers in the first conveying mechanism, and a blowing device provided at the output end of the telescopic device two and connected to an external air source. The blowing device is driven by the telescopic device two to enter the barrel to clean the inner cavity of the barrel.

[0008] A further improvement lies in that the feeding mechanism includes a feeding mechanism provided on the frame and above the third conveying mechanism, a guiding hopper provided at the tail end of the feeding mechanism, a pressing plate provided above the guiding hopper, and a driving device seven for driving the pressing plate to move up and down; The guiding hopper is used to receive the bagged raw materials conveyed by the feeding mechanism and enable the bagged raw materials to enter the barrel on the third conveying mechanism. The driving device seven is used to drive the pressing plate to pass through the guiding hopper and enter the barrel to extrude the bagged raw materials in the barrel.

[0009] A further improvement lies in that the feeding mechanism further includes arc-shaped plates symmetrically provided above both sides of the third conveying mechanism and a driving device six for driving the arc-shaped plates to move. The driving device six is used to drive the two arc-shaped plates to approach each other to extrude the bagged raw materials on the third conveying mechanism.

[0010] A further improvement lies in that the device further includes a clamping mechanism one and a clamping mechanism three with the same structure. The clamping mechanism one and the clamping mechanism three are respectively located at the tail ends of the second conveying mechanism and the third conveying mechanism and are both on the moving path of the upper cover mechanism; Among them, the clamping mechanism three includes a second bracket, two groups of movable blocks two slidably provided on the second bracket, a driving device five provided on the second bracket for driving the two movable blocks two to approach or move away from each other, two rotating rods two symmetrically and rotatably inserted on both sides of the second bracket. One end of the rotating rod two is connected with a clamping roller two for contacting the outer wall of the barrel / barrel cover through a connecting arm two. The other ends of the two rotating rods two on the same side are respectively rotatably connected to the movable block two on the same side through a connecting rod group two. The connecting rod group two drives the rotating rod two to rotate when the movable block two moves.

[0011] A further improvement lies in that the conveying mechanism III is a roller conveyor, and the device further includes a clamping mechanism II. Among them, the clamping mechanism II includes a bracket I, two groups of movable blocks I slidably arranged on the bracket I, a driving device III arranged on the bracket I for driving the two movable blocks I to approach or move away from each other, two rotating rods I symmetrically and rotatably inserted on both sides of the bracket I, one end of each rotating rod I is connected with a clamping roller I for contacting the outer wall of the barrel through a connecting arm I, the other ends of the two rotating rods I on the same side are respectively rotatably connected with the movable block I on the same side through a connecting rod group I, and the connecting rod group I drives the rotating rod I to rotate when the movable block I moves. Driving devices IV are arranged on both sides of the bracket I, and a top plate is arranged at the output end of the driving device IV. The top plate is driven by the driving device IV to pass through the roller of the conveying mechanism III and push the barrel on the conveying mechanism III upward to be butted with the discharging end of the feeding mechanism.

[0012] A further improvement lies in that the device further includes a clamping mechanism on the moving path of the cover removing mechanism. The clamping mechanism is used to clamp the barrel when the barrel moves to a preset position on the conveying mechanism I. The clamping mechanism includes two groups of clamping plates symmetrically arranged at the conveying mechanism I and a telescopic device III connected to the frame and used to drive the two clamping plates to approach or move away from each other. The clamping plate is also connected to the frame through a guiding member.

[0013] A further improvement lies in that the side pushing mechanism includes a side pushing plate arranged on the conveying mechanism I and a telescopic device IV for driving the side pushing plate to move. The telescopic device IV is connected to the frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: During the process of the cover removing mechanism of the present invention conveying the barrel, the barrel cover is automatically removed and transferred to the conveying mechanism II for temporary storage. When the barrel is conveyed to the flipping station, the flipping mechanism precisely clamps the barrel and drives it to flip to an inverted state, so that the cleaning mechanism can clean the inner wall of the barrel. After the cleaning is completed, the flipping mechanism returns the barrel to the upright state, and then the side pushing mechanism immediately pushes it onto the conveying mechanism III for conveying. During the conveying process, the feeding mechanism puts the bagged raw materials into the barrel, and then the cover putting mechanism transfers and seals the barrel cover temporarily stored on the conveying mechanism II to the barrel that has completed the feeding. This integrated design not only ensures the storage quality of the bagged raw materials, eliminates the pollution risk brought by manual intervention, but also integrates multiple processes such as cover removing, cleaning, feeding, and cover sealing into a continuous automated process, significantly reducing the labor intensity of the operators and improving the overall work efficiency.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1 Please refer to the attached Figures 1-7 , a cleaning, feeding and conveying device for a barrel for chemical raw materials, including a frame 1; It further includes a first conveying mechanism 2, a second conveying mechanism 3, a third conveying mechanism 7, a flipping mechanism 6, a cleaning mechanism 13, a lid removing mechanism 4, a lid covering mechanism 12, a feeding mechanism 11 and a side pushing mechanism arranged on the frame 1; For example, the second conveying mechanism 3 and the third conveying mechanism 7 are both vertically on one side of the first conveying mechanism 2, the flipping mechanism 6 is arranged at the end of the first conveying mechanism 2, and the cleaning mechanism 13 corresponds to the flipping mechanism 6; The barrel body (including the barrel lid) is conveyed by the first conveying mechanism 2. The first conveying mechanism 2 is used to convey the barrel body to the flipping mechanism 6. The lid removing mechanism 4 is used to transfer the barrel lid on the barrel body on the first conveying mechanism 2 to the second conveying mechanism 3. Before the barrel body is conveyed to the flipping mechanism 6, the barrel lid on the barrel body will be transferred by the lid covering mechanism 12 first. The flipping mechanism 6 is used to clamp the barrel body and drive it to flip to an inverted state or a right-side-up state. When the barrel body is in the right-side-up state, the barrel opening of the barrel body faces upward. When the barrel body is in the inverted state, the barrel opening of the barrel body faces downward. The second conveying mechanism 3 is used to convey the barrel lid. The cleaning mechanism 13 is used to clean the inside of the barrel body in the inverted state. Because the barrel opening of the barrel body faces downward when the barrel body is in the inverted state, the impurities or particles removed from the inside of the barrel body by the cleaning mechanism 13 can be separated from the barrel body. The side pushing mechanism is used to drive the barrel body to move from the first conveying mechanism 2 to the third conveying mechanism 7 after the barrel body is cleaned and reset to the right-side-up state. The reset of the barrel body after cleaning is driven by the flipping mechanism 6. The third conveying mechanism 7 is used to convey the cleaned barrel body. The conveying directions of the third conveying mechanism 7 and the second conveying mechanism 3 are the same. The feeding mechanism 11 is used to put the bagged raw materials into the barrel body when the third conveying mechanism 7 conveys the barrel body to a preset position. This preset position is where the barrel body corresponds exactly to the discharging end of the feeding mechanism 11. The lid covering mechanism 12 is used to transfer the barrel lid on the second conveying mechanism 3 to the barrel body to be fed to seal the barrel body.

[0019] Preferably, both the third conveying mechanism 7 and the first conveying mechanism 2 in this embodiment are roller conveyors, while the second conveying mechanism 3 can adopt a belt conveyor. Roller conveyors and belt conveyors are both conventional mechanisms in the art and will not be described in detail here.

[0020] Preferably, the lid removing mechanism 4 and the lid covering mechanism 12 in this embodiment have the same structure; Among them, the lid unloading mechanism 4 includes a horizontal moving device 41 connected to the frame 1 and located above the second conveying mechanism 3. The horizontal moving device 41 is, for example, a chain drive device or an electric guide rail device, etc. A carrier 42 is provided at the output end of the horizontal moving device 41. A first telescopic device 43 (such as a hydraulic cylinder, etc.) is provided on the carrier 42. A negative pressure suction head 44 for adsorbing the bucket lid is provided at the output end of the first telescopic device 43. The negative pressure suction head 44 is connected to an external negative pressure device, such as a vacuum suction cup; Taking the lid unloading mechanism 4 as an example, during use, the horizontal moving device 41 drives the carrier 42 to move to the first conveying mechanism 2. The first telescopic device 43 drives the negative pressure suction head 44 to move downward to adsorb the bucket lid on the bucket body of the first conveying mechanism 2. Subsequently, the first telescopic device 43 drives the negative pressure suction head 44 to move upward so that the bucket lid is separated from the bucket body. Then, the horizontal moving device 41 drives the carrier 42 to move back to above the second conveying mechanism 3. The first telescopic device 43 drives the negative pressure suction head 44 to move downward again. The negative pressure suction head 44 stops adsorbing and the bucket lid falls onto the second conveying mechanism 3; Taking the lid covering mechanism 12 as an example, during use, the first telescopic device 43 drives the negative pressure suction head 44 to move downward to adsorb a bucket lid on the second conveying mechanism 3. Subsequently, the horizontal moving device 41 drives the carrier 42 to move to the third conveying mechanism 7. Then, the first telescopic device 43 drives the negative pressure suction head 44 to move downward so that the bucket lid covers the top of the bucket body on the third conveying mechanism 7. Then, the negative pressure suction head 44 stops adsorbing and moves upward. Then, the horizontal moving device 41 drives the carrier 42 to reset.

[0021] Preferably, the tipping mechanism 6 of this embodiment includes a lifting mechanism 61 (such as a chain drive device or an electric guide rail device, etc.) provided on the frame 1, a movable seat 62 driven by the lifting mechanism 61 to move up and down, two groups of clamping arms 63 symmetrically provided on one side of the movable seat 62, a first driving device 64 (such as two groups of hydraulic cylinders provided on the movable seat 62 and respectively connected to the two groups of clamping arms 63, etc.) provided on the movable seat 62 for driving the two clamping arms 63 to approach or move away from each other, a clamping head 65 (such as an arc-shaped clamping block or a mounting seat with an arc-shaped groove, and a roller structure for contacting the outer wall of the bucket is rotatably provided in the mounting seat, etc.) rotatably provided on the clamping arm 63 through a rotating shaft for contacting the outer wall of the bucket, a second driving device 67 (such as a rotating motor and a reducer, or including a hydraulic cylinder, a rack provided at the output end of the hydraulic cylinder, and a gear sleeved on the rotating shaft end of the clamping head 65 and meshing with the rack, etc.) provided on one clamping arm 63 for driving the corresponding clamping head 65 to rotate, and a counterweight 66 provided on the rotating shaft of the other clamping head 65 for keeping the clamping head 65 balanced. The counterweight 66 is, for example, a counterweight block to keep the clamping head 65 in a parallel state when not rotating; The working principle of the flipping mechanism 6 is as follows: when the barrel is conveyed to the flipping mechanism 6 by the first conveying mechanism 2, the lifting mechanism 61 drives the movable seat 62 downward to the required position. Subsequently, the first driving device 64 drives the two clamping arms 63 to approach each other to clamp the barrel through the clamping head 65. Then, the lifting mechanism 61 drives the movable seat 62 upward to the preset position. At the same time, the second driving device 67 drives one clamping head 65 to rotate 180 degrees, so that the barrel rotates from the upright state to the inverted state. After the barrel is cleaned by the cleaning mechanism 13, the flipping mechanism 6 rotates the barrel from the inverted state to the upright state, and then controls the flipping mechanism 6 to reset and separate from the barrel.

[0022] Preferably, the cleaning mechanism 13 of this embodiment includes a second telescopic device (such as a hydraulic cylinder, etc.) provided on the frame 1 and below the adjacent rollers in the first conveying mechanism 2, and a blowing device (such as an air outlet nozzle, etc., of course, it is not limited to this one) provided at the output end of the second telescopic device and connected to an external air source. The blowing device is driven by the second telescopic device to enter the barrel to clean the inner cavity of the barrel. The working principle of the cleaning mechanism 13 is as follows: when the barrel rotates to the inverted state, control the second telescopic device to drive the blowing device upward. Then, the blowing device passes through the position between the adjacent rollers in the first conveying mechanism 2 and enters the inner cavity of the barrel. Then, an external air source supplies gas to the blowing device, and the blowing device cleans the inner cavity of the barrel to remove sundries, particles, etc. in the inner cavity of the barrel.

[0023] Preferably, the feeding mechanism 11 of this embodiment includes a feeding mechanism 111 (preferably a belt conveyor) provided on the frame 1 and above the third conveying mechanism 7, a guiding hopper 114 provided at the tail end of the feeding mechanism 111 (one end of the guiding hopper 114 is provided with an opening connected to the tail end of the feeding mechanism 111), a pressing plate 115 provided above the guiding hopper 114, and a seventh driving device 116 (such as a hydraulic cylinder, etc.) for driving the pressing plate 115 to move up and down. The seventh driving device 116 can be connected to the frame 1 through a mounting bracket. The guiding hopper 114 is used to receive the bagged raw materials conveyed by the feeding mechanism 111 and make the bagged raw materials enter the barrel on the third conveying mechanism 7. The seventh driving device 116 is used to drive the pressing plate 115 to pass through the guiding hopper 114 and enter the barrel to squeeze the bagged raw materials in the barrel. Because the top of the bagged raw materials may be higher than the opening plane of the barrel after the bagged raw materials enter the barrel, which will affect the subsequent capping. Therefore, after the bagged raw materials enter the barrel, the seventh driving device 116 drives the pressing plate 115 to squeeze the bagged raw materials to ensure that the top of the squeezed bagged raw materials is completely below the opening plane of the barrel, avoiding the situation that the subsequent barrel lid cannot be normally closed due to the too high bagged raw materials.

[0024] The working principle of the feeding mechanism 11 is as follows: When the side-pushing mechanism pushes the barrel from the conveying mechanism 1 to the conveying mechanism 3, the conveying mechanism 3 transports the barrel to the lower part of the feeding hopper 114. Subsequently, the feeding mechanism 111 transports the bagged raw materials to the feeding hopper 114. Under the action of gravity, the bagged raw materials slide down along the inner wall of the feeding hopper 114 and accurately fall into the barrel. Then, the driving device 7 drives the pressing plate 115 to move downward in the vertical direction, so that the pressing plate 115 passes through the internal space of the feeding hopper 114 and the opening of the barrel in sequence and enters the barrel to axially extrude the bagged raw materials. After extrusion, the pressing plate 115 resets upward, and the conveying mechanism 3 continues to convey the barrel.

[0025] Preferably, the side-pushing mechanism of this embodiment includes a side-pushing plate 14 provided on the conveying mechanism 1 (the side-pushing plate 14 can be placed above the roller of the conveying mechanism 1 or movably sleeved on the roller of the conveying mechanism 1), and a telescopic device 4 (such as a hydraulic cylinder, etc.) for driving the side-pushing plate 14 to move. The telescopic device 4 is connected to the frame 1. The moving direction of the side-pushing plate 14 is the same as the conveying direction of the conveying mechanism 3 and is exactly corresponding to the conveying mechanism 3.

[0026] Embodiment 2 Please refer to the appendix Figures 1-7 On the basis of Embodiment 1, the feeding mechanism 11 further includes arc-shaped plates 112 symmetrically arranged above both sides of the conveying mechanism 3 and a driving device 6 for driving the arc-shaped plates 112 to move. The driving device 6 is preferably two groups of hydraulic cylinders independently connected to the two arc-shaped plates 112 respectively. The hydraulic cylinders are fixedly installed on the conveying frame of the conveying mechanism 3. The driving device 6 is used to drive the two arc-shaped plates 112 to approach each other to squeeze the bagged raw materials on the conveying mechanism 3 to deform and enter the feeding hopper 114 and the barrel. Because the bagged raw materials are usually flat after being filled with raw materials, by driving the two arc-shaped plates 112 to approach each other to squeeze the bagged raw materials, they can be squeezed into an oval shape, thereby effectively reducing the lateral dimension of the bagged raw materials and making them enter the channel of the feeding hopper 114 and the barrel more smoothly. At the same time, through the shape change of ovalization, it is ensured that the bagged raw materials can stably slide down along the inner wall of the feeding hopper 114 and accurately fall into the barrel under the action of gravity.

[0027] Embodiment 3 Please refer to the appendix Figures 8-10 On the basis of Embodiment 1, the device further includes a clamping mechanism 1 5 and a clamping mechanism 3 9 with the same structure. The clamping mechanism 1 5 and the clamping mechanism 3 9 are respectively located at the tails of the conveying mechanism 2 and the conveying mechanism 3 and are both on the moving path of the upper cover mechanism 12. The clamping mechanism 1 5 and the clamping mechanism 3 9 are used to position the barrel cover and the barreled body after feeding respectively. Among them, the clamping mechanism III 9 includes a bracket II 91 fixedly installed on the frame 1 or the conveying frame of the conveying mechanism III 7 (the bracket II 91 of the clamping mechanism I 5 can be connected to the frame 1 or the conveying frame of the conveying mechanism II 3), two groups of movable blocks II 96 slidably arranged on the bracket II 91, a driving device V 95 arranged on the bracket II 91 for driving the two movable blocks II 96 to approach or move away from each other. The above driving device V 95 is, for example, a rhombic block driven to rotate by a hydraulic cylinder and a connecting rod I, and connecting rods II respectively rotatably connected to the rhombic block and the movable block II 96. Of course, the driving device V 95 is not limited to this type. Two rotating rods II 92 are symmetrically and rotatably inserted on both sides of the bracket II 91. One end of the rotating rod II 92 is connected through a connecting arm II 93 with a clamping roller II 94 for contacting the outer wall of the barrel body / barrel cover. The other ends of the two rotating rods II 92 on the same side are respectively rotatably connected to the movable block II 96 on the same side through a connecting rod group II 97 (two rotatably connected connecting rod members). The connecting rod group II 97 on the same side is used to drive the two rotating rods II 92 on the same side to rotate in opposite directions respectively when the movable block II 96 moves; Taking the clamping mechanism I 5 clamping the barrel cover as an example, the working principle is as follows: when the barrel cover is conveyed to the end of the conveying mechanism II 3, the driving device V 95 drives the two movable blocks II 96 to move. Then, the two movable blocks II 96 make the two rotating rods II 92 on the same side rotate in opposite directions through the connecting rod group II 97, thereby driving the clamping roller II 94 to contact and clamp the barrel cover, clamping and positioning the barrel cover on the conveying mechanism II 3. The same working principle applies to the positioning and clamping of the barrel body after feeding by the clamping mechanism III 9; It should be noted that after the upper cover mechanism 12 adsorbs the barrel cover, it is necessary to control the clamping mechanism I 5 to release the clamping of the barrel cover. After the upper cover mechanism 12 installs the barrel cover on the barrel body, the clamping mechanism III 9 can be controlled to release the clamping of the barrel body, and the barrel body is conveyed by the conveying mechanism III 7.

[0028] Preferably, the device of this embodiment further includes a second clamping mechanism 8, which is used to ensure the stable feeding of the barrel through the feeding mechanism 11; wherein, the second clamping mechanism 8 includes a first bracket 81 fixedly connected to the frame 1 or the conveying frame of the third conveying mechanism 7, two groups of first movable blocks 86 slidably arranged on the first bracket 81, and a third driving device 85 (having the same structure as the fifth driving device 95) arranged on the first bracket 81 for driving the two first movable blocks 86 to approach or move away from each other. Two first rotating rods 82 are symmetrically and rotatably inserted on both sides of the first bracket 81. One end of the first rotating rod 82 is connected with a first clamping roller 84 for contacting the outer wall of the barrel through a first connecting arm 83. The other ends of the two first rotating rods 82 on the same side are respectively rotatably connected with the first movable block 86 on the same side through a first connecting rod group 87 (two rotatably connected connecting rod members). The first connecting rod group 87 on the same side is used to drive the two first rotating rods 82 on the same side to rotate in opposite directions when the first movable block 86 moves. On both sides of the first bracket 81, there are fourth driving devices 89 (such as hydraulic cylinders, etc.). The output end of the fourth driving device 89 is provided with a top plate 88, and the top plate 88 is driven by the fourth driving device 89 to pass through the roller in the third conveying mechanism 7 and push the barrel corresponding to the feeding mechanism 11 on the third conveying mechanism 7 upward to be butted against the discharging end of the feeding mechanism 11. The working principle of the second clamping mechanism 8 is as follows: when the third conveying mechanism 7 conveys the barrel to the feeding mechanism 11, the fourth driving device 89 drives the top plate 88 upward. Then, the top plate 88 rises through the gap between the rollers in the third conveying mechanism 7 to push the barrel upward, so that the barrel contacts the bottom end of the feeding hopper 114 in the feeding mechanism 11. Subsequently, the third driving device 85 drives the two first movable blocks 86 to move, and then drives the two first rotating rods 82 on the same side to rotate in opposite directions through the first connecting rod group 87, and clamps the barrel through the first clamping roller 84 to ensure that the barrel remains stable and does not shift during the feeding process. After the feeding is completed, the third driving device 85 and the fourth driving device 89 are reset in sequence, so that the barrel falls back onto the third conveying mechanism 7 to continue conveying.

[0029] It should be noted that the first clamping rollers 84 / the second clamping rollers 94 in the above-mentioned first clamping mechanism 5, second clamping mechanism 8 and third clamping mechanism 9 are all above the corresponding feeding mechanisms.

[0030] Embodiment 4 Please refer to the appendix Figure 2On the basis of Example 1, the device further includes a clamping mechanism 10 located on the moving path of the lid removal mechanism 4. The clamping mechanism 10 is used to clamp the barrel body when the barrel body moves to a preset position on the conveying mechanism 2, so that the lid removal mechanism 4 can stably absorb the barrel cover and will not cause the barrel body to separate from the conveying mechanism 2. The clamping mechanism 10 includes two groups of symmetrically arranged clamping plates 101 located at the conveying mechanism 2, and a telescopic device 3 (for example, two groups of hydraulic cylinders) connected to the frame 1 and used to drive the two clamping plates 101 to move closer to or away from each other. The clamping plates 101 are also guided by guide members. 102 is connected to the frame 1. The guide member 102 includes, for example, a mounting frame detachably fixed to the conveying frame of the conveying mechanism 1-2, a guide sleeve fixedly inserted on the mounting frame, and a guide rod connected to the clamping plate 101 and slidingly fitted in the guide sleeve. When the barrel reaches the preset position, the telescopic device 3 pushes the two clamping plates 101 to move synchronously toward each other along the guide direction of the guide member 102, firmly clamping the barrel from both sides, providing a stable working reference for the unloading operation. After the unloading is completed, the telescopic device 3 drives the clamping plate 101 to reset and release the barrel, so that the conveying process continues; Preferably, the conveying device can be equipped with multiple position sensors at key positions of the frame 1 (such as installing a photoelectric sensor or proximity switch at the position corresponding to the clamping mechanism 10 on the conveying frame of the conveying mechanism 2). When the position sensor detects that the barrel body moves to the predetermined position, it will immediately send a trigger signal to the external PLC or central controller, and the controller will coordinate and control the orderly operation of each actuator according to the preset program logic, including but not limited to controlling the clamping mechanism 10 to clamp the barrel body, instructing the unloading mechanism 4 to perform the lid removal operation, synchronously pausing the operation of the conveying mechanism 2, and restarting the conveying process after the loading is completed, etc. A series of automated operations, thereby realizing intelligent control of the entire conveying process and precise coordination of the actions of each station.
