Description

Technical Field

[0001] The present invention relates to the technical field of palletizing machine conveying devices, and more specifically, to a palletizing machine for inorganic fertilizer production and its usage method. Background Art

[0002] A palletizing machine is an automated device specifically used for stacking products on pallets in a certain arrangement; with the expansion of agricultural production scale and the development of industrial automation, the traditional manual palletizing mode has been difficult to meet the requirements of efficiency, cost, and safety. The collaborative operation of the palletizing machine and the conveying device has become a key link in large-scale production, and its core goal is to achieve an automated palletizing process with high efficiency, low loss, and high compatibility.

[0003] In the existing inorganic fertilizer production line, the palletizing machine usually needs to cooperate with the conveying device during the process of loading bagged inorganic fertilizers into the freight car compartment. During the conveying process, when the bagged fertilizers are sent to the clamping area for palletizing, if the bags shift in position during the conveying process, it may cause the palletizing machine to fail to clamp, or even break the packaging bags, affecting production efficiency and causing material waste.

[0004] Currently, most of the deviation rectification devices used for the problem of bag deviation during the conveying process are in a continuous operation state. This working mode not only causes unnecessary energy consumption during the period when there is no bag passing through, increasing the operating cost, but also from the perspective of structural design, in order to achieve a more effective deviation rectification effect, the deviation rectification device is usually set in the middle position area of the bag height, which has a certain risk of interference with the clamping operation space of the subsequent palletizing manipulator, thus being unfavorable for the stable grasping and precise stacking of the palletizing equipment.

[0005] Based on this, the present invention discloses a palletizing machine for inorganic fertilizer production and its usage method. Summary of the Invention

[0006] To solve the problems in the background art that the deviation rectification device on the inorganic fertilizer production line causes unnecessary energy consumption and cost increase due to continuous operation, and its working position set in the middle position area of the bag has a space interference with the subsequent palletizing clamping operation, which is unfavorable for efficient and precise stacking operations, the present invention provides a palletizing machine for inorganic fertilizer production, which includes a conveying line and a supporting palletizing machine. The conveying line is divided into a conveying area, an acceleration area, and a clamping area; the conveying area includes the conveying device body and a driving device for driving the conveying device body to operate. The output end of the driving device is provided with a conveying roller, and the conveying device body realizes operation through the conveying roller; the acceleration area and the clamping area are arranged on the mounting frame, and the mounting frame is provided with an arc-shaped connecting plate. The acceleration area is connected to the conveying device body through the connecting plate;

[0007] When the product is conveyed to the clamping area, the product has no driving force. At the same time, in order to make the product in a relatively open position in the clamping area to facilitate the palletizing machine to clamp the product, before the product enters the clamping area, it is necessary to accelerate and push the product, and at the same time pre-lift the product by a certain height. In this technical solution, the acceleration area includes a chain conveyor and a number of push components arranged at equal intervals. The chain conveyor is arranged on the mounting frame, and the push components are connected to each other through the chain conveyor. A belt drive is arranged on the push component adjacent to the conveyor roller. The acceleration area is connected to the conveyor roller through the belt conveyor, and the acceleration drive of the push roller is realized by changing the size of the drive wheel.

[0008] On this basis, since the product is prone to deviation during transportation, which affects the subsequent clamping of the product by the palletizing machine, it is necessary to correct the deviation of the product. However, the existing deviation correction devices work continuously, which is not conducive to reducing energy consumption and is not convenient for the subsequent clamping of the palletizing machine. Therefore, in order to realize that the deviation correction device participates in the work only when the product enters the clamping area;

[0009] As a further improvement of this technical solution, the acceleration area and the clamping area are connected by a connecting roller. The clamping area is provided with a fishbone support component, and deviation correction components are symmetrically arranged on both sides of the fishbone support component. Lifting components are symmetrically arranged on both sides of the connecting roller. The connecting roller is connected to the deviation correction component through the lifting component. Telescopic components and clutch components are also symmetrically arranged on both sides of the connecting roller; Among them, the connecting roller realizes automatic up and down reset through the telescopic component. When the product passes through the connecting roller after acceleration, the connecting roller realizes intermittent transmission connection with the driving device through the clutch component.

[0010] As a further improvement of this technical solution, the telescopic component includes a support plate. A through hole is opened in the support plate. First chutes are opened on both sides of the through hole on the support plate. Sliders are slidably connected to the first chutes. The sliders are rotationally connected to the connecting roller. Springs are symmetrically arranged in the through hole. The sliders are connected to the support plate through the springs; In the initial state, the connecting roller is located at the top of the through hole through the slider.

[0011] As a further improvement of this technical solution, the clutch component includes a driving bevel gear rotatably connected to the mounting frame. The clutch component also includes a driven bevel gear, and the driven bevel gear is fixed at both ends of the connecting roller; A belt drive is arranged at the output end of the driving bevel gear. The driving bevel gear is connected to the output end of the push roller through the belt drive; In the initial state, the driven bevel gear is located directly above the driving bevel gear, and the driven bevel gear is disengaged from the driving bevel gear.

[0012] When the product is in the clamping area, traditionally, several rotating rods are used to support the product. In order to facilitate the product to fall into the clamping area and at the same time facilitate the clamping of the gripper of the palletizer;

[0013] As a further improvement of the technical solution, the fishbone support assembly includes a mounting rod fixed on the mounting frame, and several rotating rods are evenly and rotatably connected to the mounting rod along the product conveying direction; a baffle for preventing the product from falling off is arranged at the end of the mounting frame in the clamping area.

[0014] In another solution, since the traditional rectifying device often makes hard contact with the product during operation, on the one hand, it is not conducive to protecting the product, and secondly, the traditional hard contact. When the product falls into the clamping area, if the product falls on the rectifying rod, it will lead to low rectifying efficiency in the early stage of the product, or even rectifying failure;

[0015] As a further improvement of the technical solution, the rectifying assembly includes a mounting plate fixed on the mounting frame. A first telescopic rod is fixed at the center position of the mounting plate. The telescopic end of the first telescopic rod is rotatably connected with only a driving rod. Reciprocating lead screws are symmetrically fixed at both ends of the driving rod. The thread directions of the two reciprocating lead screws are opposite. A rectifying plate is threadedly connected to the reciprocating lead screw. Elastic telescopic rods corresponding to the rotating rods are fixed on the opposite sides of the two rectifying plates; a limiting rod for rotating and limiting the rectifying plate is fixed at the bottom of the rectifying plate. Second chutes are symmetrically opened at both ends of the mounting plate. The limiting rod is movably connected in the second chute; in the initial state, the distance between the ends of the two elastic telescopic rods arranged oppositely is greater than the width of the product, and the rectifying plate is in contact with the top of the mounting rod.

[0016] On this basis, since the traditional rectifying device is always located at the middle height of the product and continuously performs rectifying work, it is not conducive to the subsequent clamping of the palletizer;

[0017] As a further improvement of the technical solution, the rectifying assembly moves up and down in the opposite direction to the connection roller through the lifting assembly; that is to say, during the downward displacement of the connection roller, the entire rectifying assembly moves upward from the upper surface of the rotating rod to the middle of the product. When the connection roller resets, the rectifying assembly moves downward and resets, which will not cause movement interference to the palletizer. Moreover, the position of the elastic telescopic rod is arranged adjacent to the rotating rod, and the gripper of the palletizer is located in the gap between the rotating rods, which will further reduce movement interference.

[0018] Secondly, since the rectifying assembly and the connection roller move in the opposite direction up and down;

[0019] As a further improvement of the technical solution, a transmission component is provided on the deviation rectifying component. When the product passes through the connecting roller, the deviation rectifying component is in transmission connection with the driving device through the transmission component; the transmission component includes a transmission shaft, and transmission boxes are arranged at both ends of the transmission shaft. The transmission boxes are respectively rotatably connected to the output ends of the connecting roller and the driving rod. A transmission bevel gear set is arranged in the transmission box, and the output end of the connecting roller realizes variable-angle power output to the driving rod through the transmission bevel gear set and the transmission shaft.

[0020] As a further improvement of the technical solution, the lifting component includes two sliding rods. One of the sliding rods is rotatably arranged on the transmission box at the output end of the connecting roller and is located on the side far from the connecting roller, and the other sliding rod is fixedly arranged on the side of the deviation rectifying plate away from the elastic telescopic rod; the lifting component further includes a limiting plate and a seesaw structure. The limiting plate is fixedly arranged on the mounting frame. Among them, the sliding rod near the connecting roller is slidably connected to the limiting plate, and the seesaw structure is rotatably connected to the mounting frame. The two ends of the seesaw structure are respectively rotatably connected to the deviation rectifying plate and the transmission box on the connecting roller through the sliding rods; when the product is located on the connecting roller, the connecting roller slides in the first chute through the slider, the driven bevel gear meshes with the driving bevel gear, and at this time the elastic telescopic rod rises to the middle height of the product, and the connecting roller drives the deviation rectifying plate to reciprocate on the reciprocating screw rod through the transmission component.

[0021] The second object of the present invention is to provide a method for using a palletizer for inorganic fertilizer production, and the specific steps are as follows:

[0022] S1. Send the product to the conveying device body, convey the product to a high position through the conveying device body, and send the product to the pushing component in the acceleration area for acceleration through the connection of the connecting plate;

[0023] S2. After the product enters the pushing component in the acceleration area, after being accelerated by a number of pushing components, and at the same time raising the product by a height through the convex block, the end of the product is smoothly sent onto the connecting roller;

[0024] S3. When the product passes through the connecting roller, under the action of gravity, the connecting roller slides down through the slider in the first chute, and the driven bevel gear and the driving bevel gear come into contact and mesh;

[0025] S4. The connecting roller realizes rotation through the meshing of the driven bevel gear and the driving bevel gear, and further conveys the product to the rotating rod in the clamping area with the cooperation of the convex block and the friction pad;

[0026] S5. During the process of the product gradually entering the clamping area, the reciprocating lead screw is driven by the connecting roller through the transmission component, so that the deviation rectifying plate continuously corrects the deviation of the product through the elastic telescopic rod. Finally, after the product completely enters the clamping area, the product disengages from the connecting roller. After the connecting roller resets, the deviation rectifying plate stops working, and the palletizer starts to clamp the product.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. In this palletizer for inorganic fertilizer production, by setting the connecting roller between the acceleration area and the clamping area and its linkage structure, the operation of the deviation rectifying device is automatically triggered when the product reaches the clamping area, and it does not start when the product has not arrived, avoiding the energy waste and unnecessary cost increase caused by the continuous operation of the traditional deviation rectifying device, thereby achieving energy conservation and consumption reduction and improving the economic operation of the equipment.

[0029] 2. In this palletizer for inorganic fertilizer production, through the lifting linkage structure between the connecting roller and the deviation rectifying component, that is, the seesaw structure, the deviation rectifying component only rises to the middle of the bag for deviation rectifying operation when the product enters the clamping area, and automatically resets and descends after the product leaves, not only improving the deviation rectifying efficiency, but also effectively avoiding the clamping area of the palletizing manipulator, thereby reducing spatial interference and facilitating the stability and accuracy of subsequent clamping operations.

[0030] 3. In this palletizer for inorganic fertilizer production, by adopting the deviation rectifying plate structure with an elastic telescopic rod, it can provide buffer protection when correcting the deviation of bagged inorganic fertilizer, avoiding damage to the packaging bag or deviation rectifying failure caused by hard contact. At the same time, combined with the reciprocating lead screw drive to realize the reciprocating clamping action of the deviation rectifying plate, further improving the deviation rectifying response speed and accuracy, thereby ensuring the product quality and palletizing stability.

[0050] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] The deviation rectifying device on the existing inorganic fertilizer production line causes unnecessary energy consumption and cost increase due to continuous operation, and there is a spatial interference between its working position in the middle area of the bag and the subsequent palletizing clamping operation, which is not conducive to efficient and precise stacking operations.

[0052] For this reason, the present invention provides a palletizing machine for inorganic fertilizer production. See Figures 1-4 As shown in the figure, it includes a conveyor line and a palletizing machine used in conjunction. The conveyor line is divided into a conveying area, an acceleration area, and a clamping area; the conveying area includes a conveying device body 1 and a driving device 2 for driving the conveying device body 1 to operate. A transmission roller 3 is provided at the output end of the driving device 2, and the conveying device body 1 is operated through the transmission roller 3; the acceleration area and the clamping area are arranged on the mounting frame 15, and a connecting plate 4 with an arc-shaped structure is arranged on the mounting frame 15. The acceleration area is connected to the conveying device body 1 through the connecting plate 4.

[0053] During operation, the product, that is, the inorganic fertilizer bag, is sent onto the conveying device body 1, and the product is sent to a high place through the conveying device body 1, so as to facilitate the subsequent palletizing machine to clamp the product and put it into the freight car compartment for stacking; after the product enters the conveying device body 1, it rises to the top of the conveying device body 1 and then smoothly enters the acceleration area through the connection of the connecting plate 4. The product is lifted again through the acceleration area, so as to facilitate subsequent falling into the clamping area. Since there is no driving force in the clamping area to convey the product, the product is accelerated through the acceleration area, so that the product has a certain inertia and is convenient to smoothly enter the clamping area.

[0054] Specifically, see Figures 2-5 As shown in the figure, when the product is conveyed to the clamping area, the product has no driving force. At the same time, in order to make the product in a relatively empty position in the clamping area to facilitate the palletizing machine to clamp the product, before the product enters the clamping area, it is necessary to accelerate and push the product, and at the same time, the product is pre-lifted by a certain height; the acceleration area includes a chain conveyor 5 and a number of push components 6 arranged at equal intervals. The chain conveyor 5 is arranged on the mounting frame 15, and the push components 6 are connected through the chain conveyor 5. A belt transmission device is arranged on the push component 6 adjacent to the transmission roller 3. The acceleration area is connected to the transmission roller 3 through the belt transmission device, and the acceleration transmission of the push roller 61 is realized by changing the size of the transmission wheel.

[0055] During operation, after the product enters the acceleration area, the product gradually contacts the friction pad 63. On the basis of increasing the friction force of the friction pad 63, the product is gradually pushed and accelerated. At the same time, the height of the convex block 62 is higher than that of the connecting plate 4, so the product also achieves the effect of pre-lifting.

[0056] Furthermore, see Figure 5 、 Figure 8 and Figure 9As shown in the figure, since the product is prone to deviation during transportation, which affects the subsequent clamping of the product by the palletizer, it is necessary to correct the deviation of the product. However, the existing deviation correction devices work continuously, which is not conducive to reducing energy consumption and is also not convenient for the subsequent clamping of the palletizer. Therefore, in order to correct the deviation of the product when it enters the clamping area, the deviation correction device will participate in the work. In the present invention, the acceleration area and the clamping area are connected by a connecting roller 7. A fishbone support assembly 13 is provided in the clamping area. Deviation correction assemblies 11 are symmetrically arranged on both sides of the fishbone support assembly 13. Lifting assemblies 10 are symmetrically arranged on both sides of the connecting roller 7 and the connecting roller 7 is connected to the deviation correction assemblies 11 through the lifting assemblies 10. Telescopic assemblies 8 and clutch assemblies 9 are also symmetrically arranged on both sides of the connecting roller 7. Among them, the connecting roller 7 realizes automatic up and down reset through the telescopic assembly 8. When the product passes through the connecting roller 7 after acceleration, the connecting roller 7 realizes intermittent transmission connection with the driving device 2 through the clutch assembly 9;

[0057] Specifically, the telescopic assembly 8 includes a support plate 81. A through opening 82 is formed in the support plate 81. First sliding grooves 85 are formed on the support plate 81 on both sides of the through opening 82. Sliders 83 are slidably connected to the first sliding grooves 85. The sliders 83 are rotatably connected to the connecting roller 7. Springs 84 are symmetrically arranged in the through opening 82. The sliders 83 are connected to the support plate 81 through the springs 84. In the initial state, the connecting roller 7 is located at the top of the through opening 82 through the sliders 83;

[0058] Secondly, the clutch assembly 9 includes a driving bevel gear 91 rotatably connected to the mounting frame 15. The clutch assembly 9 also includes a driven bevel gear 92 which is fixedly arranged at both ends of the connecting roller 7. A belt transmission device is arranged at the output end of the driving bevel gear 91. The driving bevel gear 91 is connected to the output end of the pushing roller 61 through the belt transmission device. In the initial state, the driven bevel gear 92 is located directly above the driving bevel gear 91 and the driven bevel gear 92 is disengaged from the driving bevel gear 91.

[0059] During operation, when the product is lifted through the acceleration and gradual advancement of the bumps 62 and the friction pads 63, the product contacts the connecting roller 7 and presses down the connecting roller 7 under the action of gravity, causing the connecting roller 7 to slide down through the slider 83 in the first chute 85. During this process, the driven helical gear 92 will engage with the driving helical gear 91. It should be noted that the elastic force of the spring 84 is much smaller than the gravity of the product. Therefore, after a small part of the product enters onto the connecting roller 7, it will press the connecting roller 7 to displace downward. When the driven helical gear 92 engages with the driving helical gear 91, the driving helical gear 91 itself is connected to the pushing roller 61 through belt transmission. Therefore, it will drive the driven helical gear 92 to rotate, thereby driving the connecting roller 7 to rotate, enabling the product to continuously advance towards the clamping area under the combined action of inertia, the connecting roller 7, and the pushing assembly 6. At the same time, since the connecting roller 7 starts to rotate at this time and drives the deviation rectifying assembly 11 to start working. When the product completely falls into the clamping area, the product disengages from the connecting roller 7. Then the connecting roller 7 also disengages from the engagement with the driving helical gear 91 through the driven helical gear 92, and the connecting roller 7 stops working, and the deviation rectifying assembly 11 then stops working, achieving energy savings. At the same time, after the deviation rectifying assembly 11 stops working, the product deviation rectification is completed, facilitating the subsequent work of the palletizer.

[0060] Furthermore, as shown in Figure 6 As shown, when the product is in the clamping area, traditionally, several rotating rods are used to support the product. To facilitate the product to fall into the clamping area and for the gripper of the palletizer to grip, the fishbone support assembly 13 includes a mounting rod 131 fixedly arranged on the mounting frame 15. A number of rotating rods 132 are evenly rotatably connected to the mounting rod 131 along the product conveying direction; a baffle 14 for preventing the product from falling off is arranged at the end of the mounting frame 15 in the clamping area.

[0061] Secondly, since the traditional correction device often has hard contact with the product when working, it is not conducive to protecting the product. Secondly, the traditional hard contact will cause the product to fall into the clamping area. If the product falls on the correction rod, it will lead to low efficiency of product correction in the early stage, or even correction failure. Therefore, the present invention adopts a correction component 11 including a mounting plate 111 fixed on the mounting frame 15, a first telescopic rod 112 is fixed at the center of the mounting plate 111, and the telescopic end of the first telescopic rod 112 rotates only the driving rod 113, and the two ends of the driving rod 113 are symmetrically fixed with reciprocating screws 118, and the two reciprocating screws The thread directions of 118 are opposite, and a correcting plate 114 is threadedly connected to the reciprocating screw 118. An elastic telescopic rod 115 corresponding to the rotating rod 132 is fixedly arranged on the opposite side of the two correcting plates 114; a limiting rod 116 for limiting the rotation of the correcting plate 114 is fixedly arranged at the bottom of the correcting plate 114, and second sliding grooves 117 are symmetrically opened at both ends of the mounting plate 111, and the limiting rod 116 is movably connected in the second sliding groove 117; in the initial state, the distance between the ends of the two elastic telescopic rods 115 arranged opposite to each other is greater than the width of the product, and the correcting plate 114 is in contact with the top of the mounting rod 131.

[0062] When working, refer to Figure 3 As shown by the middle dotted line, the dotted part is a schematic diagram of the product. When the connecting roller 7 moves downward, the driving rod 113 is driven to rotate through the transmission. The correcting plate 114 is under the limiting action of the limiting rod 116, and the threaded areas of the two reciprocating screws 118 arranged in opposite directions are in opposite directions. Therefore, the correcting plate 114 realizes relative reciprocating motion, and the elastic telescopic rod 115 is elastically retractable. In this way, in the process of the correcting plate 114 driving the elastic telescopic rod 115 to reciprocate and continuously clamp and correct the deviation, the product is protected by the elastic telescopic buffer. Secondly, because the elastic telescopic rod 115 is elastically retractable, when the product just enters the clamping area for correction, even if the product presses the elastic telescopic rod 115, then in the process of the reciprocating of the elastic telescopic rod 115, combined with the elastic force and the back-and-forth friction at the end of the elastic telescopic rod 115, the efficiency of product correction will be accelerated. Compared with the traditional non-elastic correcting rod, it is easy to cause the correcting rod to move back and forth under the product all the time, and the correction effect cannot be achieved.

[0063] In addition, refer to Figure 7 and Figure 10As shown, since the traditional deflection correction device is always located at the middle height of the product and the continuous deflection correction work is not conducive to the subsequent clamping of the palletizer, the present invention adopts the deflection correction component 11 to realize the up-down opposite movement of the connecting roller 7 through the lifting component 10; that is, during the downward displacement of the connecting roller 7, the entire deflection correction component 11 starts to move upward from the upper surface of the rotating rod 132 to the middle of the product, and when the connecting roller 7 is reset, the deflection correction component 11 moves downward and resets, which will not cause motion interference to the palletizer, and the position of the elastic telescopic rod 115 is set adjacent to the rotating rod 132, and the clamping claw of the palletizer is located in the gap between the rotating rods 132, which will further reduce motion interference;

[0064] In addition, since the correcting component 11 and the connecting roller 7 realize opposite movements up and down, which is similar to the seesaw principle, in order to realize power transmission during the opposite movements of the correcting component 11 and the connecting roller 7, a transmission component 12 is provided on the correcting component 11. When the product passes through the connecting roller 7, the correcting component 11 is connected to the driving device 2 through the transmission component 12.

[0065] Specifically, the transmission assembly 12 includes a transmission shaft 121, and transmission boxes 122 are provided at both ends of the transmission shaft 121. The transmission box 122 is rotatably connected to the output ends of the connecting roller 7 and the driving rod 113 respectively. A transmission bevel gear set 123 is provided in the transmission box 122. The output end of the connecting roller 7 realizes the power output of the driving rod 113 with a changeable angle through the transmission bevel gear set 123 and the transmission shaft 121.

[0066] Secondly, the lifting assembly 10 includes two slide bars 101, one of which is rotatably arranged on a transmission box 122 on the output end of the connecting roller 7 and is located on a side away from the connecting roller 7, and the other slide bar 101 is fixedly arranged on a side of the correction plate 114 away from the elastic telescopic rod 115;

[0067] The lifting assembly 10 further includes a limit plate 102 and a seesaw structure 103, wherein the limit plate 102 is fixedly mounted on the mounting frame 15, wherein a slide bar 101 adjacent to the connecting roller 7 is slidably connected to the limit plate 102, and the seesaw structure 103 is rotatably connected to the mounting frame 15, and both ends of the seesaw structure 103 are rotatably connected to the correction plate 114 and the transmission box 122 on the connecting roller 7 through the slide bar 101;

[0068] When the product is located on the connecting roller 7, the connecting roller 7 slides in the first slide groove 85 through the slider 83, the driven bevel gear 92 engages with the driving bevel gear 91, and at this time the elastic telescopic rod 115 rises to the mid-height of the product, and the connecting roller 7 drives the correcting plate 114 to reciprocate on the reciprocating screw 118 through the transmission assembly 12.

[0069] During operation, when the connecting roller 7 starts to move downward, the seesaw structure 103 drives the entire deviation correction plate 114 to move upward. During the upward movement of the deviation correction plate 114, the first telescopic rod 112 provides support, and the first telescopic rod 112 is telescopic. At the same time, the length of the limit rod 116 is such that the limit rod 116 does not disengage from the second sliding groove 117 during the up and down movement in the second sliding groove 117, ensuring that the limit rod 116 always limits the deviation correction plate 114; in this way, through the existing mature structure of the seesaw structure 103, the effect of opposite displacement directions of the connecting roller 7 and the deviation correction plate 114 is achieved; and during the displacement of the connecting roller 7 and the driving rod 113, it is ensured that power is always transmitted. By borrowing the transmission principle of an automobile chassis, that is, the structural characteristics of the transmission shaft 121, it is ensured that power can still be transmitted when the connecting roller 7 and the driving rod 113 move up and down. This is an existing mature technology, and the specific structural features will not be elaborated too much;

[0070] It should be noted that the sliding rod 101 on the connecting roller 7 is slidably connected to the limiting plate 102 to prevent the rotation of the connecting roller 7 from interfering with the seesaw structure 103. At the same time, the length of the sliding rod 101 on the deviation correction plate 114 is relatively long to ensure that the sliding rod 101 does not disengage from the contact with the seesaw structure 103 during the reciprocating movement of the deviation correction plate 114.

[0071] In summary, by optimizing the partition structure of the conveyor line, introducing a linkage deviation correction control mechanism and a flexible deviation correction actuator; thus effectively solving the problems that the deviation correction device on the existing inorganic fertilizer production line causes unnecessary energy consumption and cost increase due to continuous operation, and its working position set in the middle area of the bag has a spatial interference with the subsequent palletizing clamping operation, which is not conducive to efficient and accurate stacking operations.
