Description

Technical Field

[0001] This invention belongs to the field of suspended conveying technology, specifically relating to a suspended conveying system and a large-volume intelligent suspended delivery process for powder materials. Background Technology

[0002] The overhead conveyor system transports ton bags containing powder via an overhead track. In use, hooks are typically used to hook the ton bags onto the lifting straps to suspend them, allowing the ton bags to move away from the ground.

[0003] In existing technologies, large quantities of powder need to be unloaded as soon as possible when they are fed. However, the powder is prone to bridging (caused by the cohesiveness of the powder) and wall adhesion (caused by the adhesiveness of the powder) in the ton bag, which affects the discharge efficiency of the powder in the ton bag. In addition, after the hook catches the lifting strap of the ton bag, the ton bag is prone to shaking during movement, especially during start-up and stop, which affects stability. Some overhead conveying systems reduce the speed of movement and start-up and stop in exchange for stability, but this method reduces the conveying efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a suspended conveying system and a large-volume intelligent suspended feeding process for powder materials. Through the lifting frame and rotating arm, the system can not only limit the position of the ton bags to improve the stability of the ton bag conveying, but also drive the ton bags to move up and down and tap them to reduce arching and hanging on the walls, thereby improving the discharge efficiency of powder materials in the ton bags.

[0009] In a preferred embodiment of the suspended conveying system of the present invention, the actuator includes a limiting plate disposed on the lower arm section, the limiting plate being fixedly connected to the lower arm section, and a plurality of action plates disposed on the limiting plate, the action plates being detachably installed together with the limiting plate.

[0010] In a preferred embodiment of the suspended conveying system of the present invention, the mobile frame is provided with a plurality of third telescopic rods, the third telescopic rods are fixedly connected to the mobile frame, the output end of the third telescopic rods is fixedly connected to the lifting frame, and the mobile frame is provided with a plurality of fourth telescopic rods, the fourth telescopic rods are fixedly connected to the mobile frame, and the output end of the fourth telescopic rods is fixedly connected to the lifting plate.

[0011] In a preferred embodiment of the suspended conveying system of the present invention, the hook is slidably connected to the lifting frame, the lifting frame is provided with a plurality of fifth telescopic rods, the number of the fifth telescopic rods is equal to the number of hooks and they correspond one-to-one, the fifth telescopic rods are fixedly connected to the lifting frame, and the output end of the fifth telescopic rods is fixedly connected to the hooks.

[0012] In a preferred embodiment of the suspended conveying system of the present invention, the lifting plate has a through hole, and a plurality of sixth telescopic rods are provided on the outside of the through hole. The sixth telescopic rods are fixedly connected to the lifting plate, and a clamping block is provided at the output end of the sixth telescopic rod. The clamping block is fixedly connected to the output end of the sixth telescopic rod.

[0013] As a preferred embodiment of the suspended conveying system of the present invention, the lifting frame is provided with a plurality of notches, the notches are located on the edge of the lifting frame near the rotating arm, the notches are recessed inward toward the side away from the rotating arm, and the number of notches is equal to that of the rotating arm and they correspond one-to-one.

[0014] The intelligent overhead conveying process for large-volume powder materials using an overhead conveying system comprises the following steps: S1: The ton bag containing powder is suspended on the lifting frame by the hook. After the moving component slides along the track, it drives the suspension structure and the ton bag to move. After the lifting frame slides upward along the moving frame, it drives the ton bag to move upward, so that the lifting plate limits the ton bag from above. After the lifting frame slides upward, it also drives the rotating arm to rotate, so that the rotating arm limits the ton bag from the side. S2: After the ton bag is moved to the unloading point, the moving component stops moving to unload the ton bag. The lifting frame moves back and forth downward and upward, causing the lower end of the rotating arm to rotate back and forth outward and inward to pat the ton bag. S3: After unloading is completed, the moving component slides along the track, causing the ton bag to leave the unloading point, thereby realizing the delivery of powder.

[0015] The technical effects achieved by this invention are as follows: This invention employs a lifting frame and a rotating arm design. When the lifting frame moves upward, it can not only lift the ton bag via the hook and increase the distance between the ton bag and the ground, but also drive the rotating arm to rotate after the lifting frame moves upward. This causes the lower end of the rotating arm to rotate inward and limit the ton bag, improving the stability of the ton bag during the conveying process along the track. Compared with the prior art, this reduces the swaying of the ton bag during movement, especially during start-stop, and also reduces the situation where the conveying efficiency is reduced by lowering the movement and start-stop speed in exchange for stability. This makes it easier to suspend and convey ton bags containing powder. This invention employs a lifting frame and a rotating arm design. After the lifting frame is raised and lowered, it not only moves the ton bag up and down, allowing it to move up and down during unloading to loosen the powder adhering to the inner wall of the ton bag and facilitate breaking the arch bridge structure formed in the powder, but also drives the rotating arm to rotate, causing the lower end of the rotating arm to pat the side wall of the ton bag to loosen the powder adhering to the inner wall of the ton bag and facilitate breaking the arch bridge structure formed in the powder. This reduces arch bridges and wall adhesion, and compared with the prior art, it is easier to improve the discharge efficiency of powder in the ton bag, thus facilitating the delivery of large quantities of powder. This invention employs a lifting frame and lifting plate design. The lifting plate not only limits the ton bag from above, improving stability during the transport of the ton bag along the track, but the lifting frame can also move upward along the moving frame, increasing the maximum distance the lifting frame can move the ton bag upward. This increases the maximum angle at which the lower end of the rotating arm rotates inward, facilitating the lower end of the rotating arm to pat the ton bag. Attached Figure Description

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0019] Example 1 like Figures 1 to 7 As shown, this is the first embodiment of the present invention. This first embodiment provides a suspended conveying system and a large-volume intelligent suspended feeding process for powder materials. It includes a conveying structure 10, which includes a track 11, on which a plurality of moving components 12 are slidably installed; and a suspension structure 20, which includes a plurality of suspension structures, all located on the conveying structure 10. The suspension structure 20 includes a moving frame 21 fixedly connected to the moving components 12. A lifting frame 22 and a lifting plate 23 are slidably installed on the moving frame 21. The lifting frame 22 is located above the lifting plate 23. A plurality of hooks 24 are installed on the lifting frame 22. A plurality of rotating arms 25 are rotatably connected to the moving frame 21. The upper ends of the rotating arms 25 are slidably installed together with the lifting frame 22.

[0020] It should be noted that this invention applies to ton bags, which are used to load powder (not shown in the figure). Ton bags are existing technology, also known as ton bags, and typically consist of a bag body and lifting straps. In this invention, a square bag body is preferred. There are four lifting straps, all sewn to the bag body. The straps are folded back at the top and securely sewn together to form a sturdy fabric loop. The four loops are located at the four corners of the top of the bag body, used by hooks 24 to hook onto the loops and lift the ton bag. A feed inlet is located at the top of the bag body for adding powder, and a discharge outlet is located at the bottom for discharging powder. Both the feed inlet and discharge outlet are tubular structures made of rolled fabric. After loading, they are closed by wrapping and securing with ropes (not shown in the figure). The ropes are loosened to open during unloading. 11 is existing technology, which is suspended from the top of the workshop (not shown) by connecting a base plate (not shown) and a hanging rod (not shown) to bear weight and provide a conveying path. The conveying structure 10 also includes a traction assembly, a drive assembly, a tensioning assembly, and a control assembly (all not shown) set on the track 11. The traction assembly, drive assembly, tensioning assembly, and control assembly are all existing technologies. The traction assembly includes a traction chain, which is pulled by the drive assembly and circulates within the track 11. The drive assembly includes a drive motor, a reducer, and a drive sprocket to drive the entire traction chain. The tensioning assembly includes a tensioning frame, a sliding frame, a tensioning sprocket, and a spring to adjust the tension of the traction chain, prevent excessive sag of the traction chain, and control the tension. The components include a programmable logic controller (PLC) and a safety controller for controlling the start, stop, and speed of the drive motor. The moving component 12 is existing technology. In this invention, the moving component 12 is preferably a carrying trolley. The moving component 12 is connected to a traction chain via a push rod, and is thus moved by the traction chain. The moving component 12 is equipped with wheels (not shown) to roll on the track 11. The moving component 12 and the track 11 are slidably mounted together via the traction chain and wheels. The number of hooks 24 is equal to the number of fabric rings. In this invention, four hooks 24 are preferred, and each hook 24 is used to hook one fabric ring. During use, to avoid uneven force on the sling causing the ton bag to tip over, the four hooks 24 simultaneously and evenly hook four fabric rings for easy suspension. The number of suspension structures 20 is not less than the number of ton bags being transported. One ton bag occupies one suspension structure 20 for transporting the ton bag. The cross-sectional shape of the moving frame 21 is an inverted "T" shape. The moving frame 21 includes a vertical column and a flat plate integrally connected to the lower end of the column. The top of the column of the moving frame 21 is fixedly connected to the moving assembly 12 by bolts (not shown in the figure). The flat plate of the moving frame 21 is rotatably connected to the rotating arm 25. The lifting frame 22 is located above the flat plate, and the lifting plate 23 is located below the flat plate. Four hooks 24 are located at the four corners of the lifting frame 22. The four corners of the flat plate and the four corners of the lifting plate 23 are designed with notches to leave space for the lifting of the hooks 24.To prevent the hook 24 from interfering with the flat plate and lifting plate 23 during lifting, the height of the rotating arm 25 where it is rotatably mounted with the lifting frame 22 is higher than the height of the rotating arm 25 where it is rotatably connected with the flat plate. Preferably, there are four rotating arms 25 in this invention. In the initial state, the ton bag is suspended on the suspension structure 20, with the four rotating arms 25 located on the four sides of the ton bag. The upper ends of the rotating arms 25 are inclined inwards (i.e., towards the side closer to the column), and the lower ends of the rotating arms 25 are inclined outwards (i.e., away from the ton bag).

[0021] In use, the movable component 12 slides along the track 11, causing the suspension structure 20 to move along the track 11. The ton bag containing powder is suspended on the lifting frame 22 via the hook 24. This allows the suspension structure 20 to move along the track 11, moving the ton bag along with it, facilitating batch transport of powder. During the process of suspending the ton bag on the lifting frame 22, the hook 24 passes through the cloth ring to hook the ton bag's strap. At this time, the ton bag body is below the lifting plate 23. The lifting frame 22 slides upward along the movable frame 21, causing the ton bag to move upward via the hook 24. As the lifting frame 22 slides upward, it also causes the upper end of the rotating arm 25 to rotate outward. Because the rotating arm 25 is rotatably connected to the movable frame 21, the lower end of the rotating arm 25... The rotating arm 25 rotates inward, bringing its lower end close to and in contact with the ton bag, thus limiting its movement from the side. The lifting plate 23 slides downward along the moving frame 21 and contacts the top of the ton bag, further limiting its movement from above. This improves the stability of the ton bag during movement and reduces swaying, especially during start-up and stop, compared to existing technologies. The upward movement distance of the lifting frame 22 and the downward movement distance of the lifting plate 23 are determined through pre-conveying adjustments. During adjustment, a ton bag containing powder is suspended on the lifting frame 22, and the lifting frame 22 is gradually moved upward until the lower end of the rotating arm 25 contacts the ton bag. The lifting frame 22 is moved upwards by a distance recorded and obtained. The lifting plate 23 is then moved downwards gradually until it contacts the top of the ton bag. The downward distance of the lifting plate 23 is recorded and obtained. Thus, when using ton bags of the same size to transport the same volume of powder, only the lifting frame 22 and the lifting plate 23 need to be moved the same distance to achieve the limit. This is a conventional design method in this field and will not be elaborated further here. When the ton bag moves to the unloading point (not shown in the figure) and needs to be unloaded, the lifting frame 22 slides up and down along the moving frame 21 and then moves the ton bag up and down via the hook 24 to loosen the powder adhering to the inner wall of the ton bag, making it easier to break the arch structure formed in the powder. When the lifting frame 22 slides up and down... It also drives the rotating arm 25 to rotate. When the lifting frame 22 moves downward, it drives the upper end of the rotating arm 25 to rotate inward, causing the lower end of the rotating arm 25 to rotate outward and move away from the ton bag. When the lifting frame 22 moves upward, it drives the upper end of the rotating arm 25 to rotate outward, causing the lower end of the rotating arm 25 to rotate inward and move closer to the ton bag. Thus, the lower end of the rotating arm 25 moves away from and closer to the ton bag as the lifting frame 22 moves up and down, achieving the effect of the lower end of the rotating arm 25 patting the ton bag to loosen the powder attached to the inner wall of the ton bag. This facilitates breaking the arch bridge structure formed in the powder. By moving the ton bag up and down and patting the ton bag, the arch bridge and wall hanging situation are reduced. Compared with the existing technology, it is easier to improve the discharge efficiency of powder in the ton bag. In this invention, the amplitude and frequency of the vertical movement of the lifting frame 22 are not fixedly limited, but their setting should follow the following principles: avoid using long-term, high-frequency, and large-amplitude violent movements to prevent the powder from being compacted due to excessive vibration; for ton bags with large load capacity, avoid moving the ton bags vertically at a large amplitude in the initial stage of unloading; the amplitude and frequency of moving the ton bags vertically and tapping the ton bags are preset by the operator based on experience and are adaptively adjusted according to the actual situation of the powder being transported. For example, for powders with poor flowability, a medium amplitude is used initially and then a small amplitude is used later. This is a conventional design method in the field and will not be elaborated here. Furthermore, due to the obstruction of the lifting plate 23 above the ton bag, the maximum distance that the lifting frame 22 can move the ton bag upward via the hook 24 is limited. This, in turn, limits the maximum angle at which the lower end of the rotating arm 25 can rotate inward. After the powder in the ton bag is unloaded, the side wall of the ton bag retracts inward, reducing the horizontal dimension of the ton bag. This may result in the lower end of the rotating arm 25 being unable to reach the ton bag during the tapping process. To reduce this, the lifting plate 23 moves upward along the moving frame 21, increasing the maximum distance that the lifting frame 22 can move the ton bag upward. This, in turn, increases the maximum angle at which the lower end of the rotating arm 25 can rotate inward, allowing the lower end of the rotating arm 25 to tap the ton bag. The amplitude and frequency of the lifting plate 23's rise are preset by the operator based on experience and adaptively adjusted according to the actual situation of the ton bag's side wall retracting inward. This is a conventional design method in the field and will not be elaborated further here.

[0022] Example 2 Reference Figures 1 to 10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0023] like Figure 7 and Figure 9 As shown, the lifting frame 22 is provided with a number of sliders 31, which are rotatably connected to the lifting frame 22. The number of sliders 31 is equal to that of the rotating arm 25 and they correspond one-to-one. The upper end of the rotating arm 25 is provided with a sliding rod 32, which is fixedly connected to the rotating arm 25. The sliders 31 and the sliding rod 32 are slidably connected together.

[0024] It should be noted that a linear bearing is fixedly connected inside the slider 31. The linear bearing is slidably engaged with the slide rod 32. The slider 31 and the slide rod 32 are slidably connected together through the linear bearing. The linear bearing is existing technology and is used to reduce the friction when the slide rod 32 moves relative to the slider 31. It will not be described in detail here. In this invention, the number of sliders 31 is preferably four.

[0025] According to the above structure, since the slider 31 is not only rotatably connected to the lifting frame 22, but also slidably connected to the slider 31, the lifting frame 22 drives the rotating arm 25 to rotate when it moves up and down. The center of rotation is the rotatable connection between the rotating arm 25 and the moving frame 21. When the lifting frame 22 moves upward, the lifting frame 22 drives the sliding rod 32 to rotate outward through the slider 31. In this process, the slider 31 not only rotates relative to the lifting frame 22, but also slides relative to the sliding rod 32. When the lifting frame 22 moves upward, the lifting frame 22 drives the sliding rod 32 to rotate inward through the slider 31. In this process, the slider 31 not only rotates relative to the lifting frame 22, but also slides relative to the sliding rod 32. This causes the lower end of the rotating arm 25 to rotate inward or outward, which facilitates the rotating arm 25 to limit or tap the ton bag.

[0026] like Figure 7 and Figure 8 As shown, the rotating arm 25 includes an upper arm section 41 mounted on a movable frame 21, which is rotatably connected to the movable frame 21. A middle arm section 42 is provided at the lower end of the upper arm section 41, and the middle arm section 42 is slidably mounted to the upper arm section 41. A lower arm section 43 is provided at the lower end of the middle arm section 42, and the lower arm section 43 is rotatably mounted to the middle arm section 42. An actuator 44 is mounted at the end of the lower arm section 43.

[0027] It should be noted that the slide bar 32 is located on the upper arm section 41 and is fixedly connected to the upper arm section 41. When the lower end of the rotating arm 25 limits or taps the ton bag, the part of the rotating arm 25 that contacts the side wall of the ton bag is the actuator 44.

[0028] According to the above structure, during the process of the lifting frame 22 moving up and down and driving the rotating arm 25 to rotate, the lifting frame 22 drives the upper arm section 41 to rotate along the moving frame 21. The upper arm section 41 drives the middle arm section 42, the lower arm section 43, and the actuator 44 to rotate, causing the actuator 44 to move away from or closer to the ton bag, thereby allowing the actuator 44 to limit or tap the ton bag. Specifically, after the middle arm section 42 slides along the upper arm section 41, the height of the actuator 44 increases or decreases, adjusting the relative position of the actuator 44 and the ton bag in the vertical direction. To facilitate adjustment of the position of the actuator 44 in limiting and striking the ton bag, the lower arm section 43 rotates along the middle arm section 42, thereby increasing or decreasing the relative angle between the lower arm section 43 and the middle arm section 42. By adjusting this angle, the contact area between the actuator 44 and the side wall of the ton bag can be increased when the actuator 44 limits and strikes the bag. When adjusting the position of the actuator 44 in limiting and striking the ton bag, adjusting this angle also facilitates increasing the contact area between the actuator 44 and the side wall of the ton bag when the actuator 44 limits and strikes the bag after adjustment.

[0029] like Figure 7 and Figure 8 As shown, the middle boom segment 42 is slidably connected to the upper boom segment 41. Several first telescopic rods 45 are provided on the upper boom segment 41. The first telescopic rods 45 are fixedly connected to the upper boom segment 41. The output end of the first telescopic rods 45 is fixedly connected to the middle boom segment 42. The lower boom segment 43 is rotatably connected to the middle boom segment 42. Several second telescopic rods 46 are provided between the lower boom segment 43 and the middle boom segment 42. One end of the second telescopic rod 46 is rotatably connected to the middle boom segment 42, and the other end of the second telescopic rod 46 is rotatably connected to the lower boom segment 43.

[0030] It should be noted that, in this invention, both the first telescopic rod 45 and the second telescopic rod 46 are preferably electric telescopic rods with a self-locking function. Electric telescopic rods are existing technology and will not be described in detail here. In this invention, the number of first telescopic rods 45 is preferably one, and the number of second telescopic rods 46 is preferably two.

[0031] According to the above structure, when the middle arm segment 42 needs to slide along the upper arm segment 41, the output end of the first telescopic rod 45 drives the middle arm segment 42 to move after it is working, so as to facilitate the middle arm segment 42 to slide along the upper arm segment 41. When the lower arm segment 43 needs to rotate along the middle arm segment 42, the output end of the second telescopic rod 46 extends or shortens after it is working. Since the two ends of the second telescopic rod 46 are rotatably connected to the middle arm segment 42 and the lower arm segment 43 respectively, it is convenient for the lower arm segment 43 to rotate along the middle arm segment 42.

[0032] like Figure 7 and Figure 8 As shown, the actuator 44 includes a limiting plate 47 disposed on the lower arm section 43. The limiting plate 47 is fixedly connected to the lower arm section 43. A plurality of action plates 48 are disposed on the limiting plate 47. The action plates 48 are detachably installed together with the limiting plate 47.

[0033] It should be noted that the limiting plate 47 is fixedly connected to the end of the lower arm section 43 away from the middle arm section 42. The number of actuating plates 48 is preferably three in this invention, and the three actuating plates 48 are evenly distributed on the lower edge of the execution part 44. The actuating plates 48 are made of an elastic material, preferably polyurethane in this invention. One end of the actuating plate 48 is a fixed end, which is detachably installed to the limiting plate 47 by bolts (not shown in the figure). The other end of the actuating plate 48 is a free end, which is used to contact and tap the ton bag.

[0034] According to the above structure, when it is necessary to limit the ton bag, the rotating arm 25 rotates so that the limiting plate 47 approaches and contacts the side wall of the ton bag, thereby limiting the ton bag through the limiting plate 47. When it is necessary to pat the ton bag, the lower end of the rotating arm 25 rotates outward so that the action plate 48 moves away from the ton bag, and the lower end of the rotating arm 25 rotates inward so that the action plate 48 approaches the ton bag, thereby making the free end of the action plate 48 contact and pat the ton bag.

[0035] like Figure 3 , Figure 9 and Figure 10 As shown, the movable frame 21 is provided with several third telescopic rods 51, which are fixedly connected to the movable frame 21. The output end of the third telescopic rod 51 is fixedly connected to the lifting frame 22. The movable frame 21 is provided with several fourth telescopic rods 52, which are fixedly connected to the movable frame 21. The output end of the fourth telescopic rod 52 is fixedly connected to the lifting plate 23.

[0036] It should be noted that, in this invention, both the third telescopic rod 51 and the fourth telescopic rod 52 are preferably electric telescopic rods with a self-locking function. Electric telescopic rods are existing technology and will not be described in detail here. In this invention, both the third telescopic rod 51 and the fourth telescopic rod 52 are preferably two in number. The lifting frame 22 has two first holes, which are located above the two fourth telescopic rods 52 respectively. These holes are used to prevent interference between the lifting frame 22 and the fourth telescopic rods 52 during the up-and-down movement of the lifting frame 22 along the moving frame 21. The lifting frame 22 also has a second hole for the column part of the moving frame 21 to pass through the lifting frame 22.

[0037] According to the above structure, when the lifting frame 22 needs to move up and down along the moving frame 21, the output end of the third telescopic rod 51 drives the lifting frame 22 to move, thus facilitating the lifting frame 22 to move up and down along the moving frame 21. When the lifting plate 23 needs to move up and down along the moving frame 21, the output end of the fourth telescopic rod 52 drives the lifting plate 23 to move, thus facilitating the lifting plate 23 to move up and down along the moving frame 21. Since both the lifting frame 22 and the lifting plate 23 can move up and down along the moving frame 21, when the lifting frame 22 suspends the ton bag through the hook 24 and limits the ton bag through the rotating arm 25, during the process of the lifting plate 23 moving down to limit the ton bag, the hook 24 moves down and adjusts the distance between the lifting plate 23 and the hook 24 to accommodate cloth rings of different lengths, thus facilitating the adaptation of ton bags of different specifications.

[0038] like Figure 9As shown, the hook 24 is slidably connected to the lifting frame 22. The lifting frame 22 is provided with a number of fifth telescopic rods 53. The number of fifth telescopic rods 53 is equal to that of the hook 24 and they correspond one-to-one. The fifth telescopic rods 53 are fixedly connected to the lifting frame 22. The output end of the fifth telescopic rod 53 is fixedly connected to the hook 24.

[0039] It should be noted that the fifth telescopic rod 53 is preferably an electric telescopic rod with a self-locking function in this invention. Electric telescopic rods are existing technology and will not be described in detail here. The lifting frame 22 has four sliding holes, and four hooks 24 are respectively slidably engaged with the four sliding holes. The hooks 24 and the lifting frame 22 are slidably connected together through the sliding holes, and the sliding direction is on the same straight line as the diagonal of the rectangular lifting frame 22. The extension and retraction direction of the output end of the fifth telescopic rod 53 is on the same straight line as the diagonal of the rectangular lifting frame 22.

[0040] According to the above structure, after the fifth telescopic rod 53 is working, the output end drives the hook 24 to slide along the lifting frame 22 to adjust the distance between the hooks 24, so as to adapt to square bags of different widths and to adapt to ton bags of different specifications.

[0041] like Figure 10 As shown, a through hole 54 is provided on the lifting plate 23, and several sixth telescopic rods 55 are provided on the outside of the through hole 54. The sixth telescopic rods 55 are fixedly connected to the lifting plate 23. A clamping block 56 is provided at the output end of the sixth telescopic rod 55, and the clamping block 56 is fixedly connected to the output end of the sixth telescopic rod 55.

[0042] It should be noted that the through hole 54 is used for the feed inlet of the ton bag to pass through the lifting plate 23, so as to avoid interference between the lifting plate 23 and the feed inlet during the up and down movement of the lifting plate 23. The sixth telescopic rod 55 is preferably an electric telescopic rod with a self-locking function in this invention. The electric telescopic rod is the prior art and will not be described in detail here. The number of sixth telescopic rods 55 is preferably two in this invention, and the two sixth telescopic rods 55 are symmetrically arranged on the outside of the through hole 54.

[0043] According to the above structure, when the ton bag is suspended, the lifting plate 23 moves down and contacts the top of the ton bag, so that the feed port of the ton bag passes through the through hole 54. After the sixth telescopic rod 55 works, the output end drives the clamping block 56 to move inward, so that the two clamping blocks 56 clamp and limit the feed port of the ton bag from the outside, which facilitates the improvement of the stability of the ton bag during the process of conveying the ton bag along the track 11.

[0044] like Figure 7 and Figure 9 As shown, the lifting frame 22 has several notches 57. The notches 57 are located on the edge of the lifting frame 22 near the rotating arm 25. The notches 57 are recessed inward toward the side away from the rotating arm 25. The number of notches 57 and the number of rotating arms 25 are equal and correspond one-to-one.

[0045] It should be noted that the width of notch 57 is greater than the width of rotating arm 25.

[0046] According to the above structure, the notch 57 is provided to prevent interference between the rotating arm 25 and the lifting frame 22 when the upper end of the rotating arm 25 rotates inward.

[0047] To enable those skilled in the art to further understand the suspended conveying system of the present invention, the present invention also provides a large-volume intelligent suspended feeding process for powder materials using the suspended conveying system. This process utilizes the aforementioned suspended conveying system, and the specific steps are as follows: S1: The ton bag containing powder is suspended on the lifting frame 22 by the hook 24. After the moving component 12 slides along the track 11, it drives the suspension structure 20 and the ton bag to move. After the lifting frame 22 slides upward along the moving frame 21, it drives the ton bag to move upward, so that the lifting plate 23 limits the ton bag from above. After the lifting frame 22 slides upward, it also drives the rotating arm 25 to rotate, so that the rotating arm 25 limits the ton bag from the side. S2: After the ton bag is moved to the unloading point, the moving component 12 stops moving to unload the ton bag. The lifting frame 22 moves back and forth downward and upward, causing the lower end of the rotating arm 25 to rotate back and forth outward and inward to pat the ton bag. S3: After unloading is completed, the moving component 12 slides along the track 11, causing the ton bag to leave the unloading point, thereby realizing the delivery of powder.

[0048] The working principle of this invention is as follows: The ton bag containing powder is suspended by the hook 24. After the moving component 12 slides, the ton bag moves along the track 11 through the suspension structure 20 to facilitate the batch conveying of powder. When the ton bag is suspended, the lifting frame 22 moves up and drives the rotating arm 25 to rotate, so that the rotating arm 25 limits the ton bag. The lifting plate 23 moves down and limits the ton bag, thereby improving the stability of the ton bag conveying. When the ton bag is unloaded, the lifting frame 22 moves up and down along the moving frame 21 and drives the ton bag to move up and down. The rotating arm 25 beats the ton bag to reduce arching and hanging. Compared with the prior art, it is easier to improve the discharge efficiency of powder in the ton bag.

[0049] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
