Description

Technical Field

[0001] This application relates to the field of product warranty technology, and in particular to a lifting spiral ton packaging device. Background Technology

[0002] A spiral ton packaging unit is a device used to package large quantities of powdery, granular, and other materials into ton bags. It can quickly and efficiently complete ton bag packaging, meeting the needs of large-scale production. For example, in large cement plants or chemical raw material processing plants, several bags of products need to be packaged every day. The spiral ton packaging unit can significantly improve production efficiency, shorten the production cycle, reduce manual intervention, and lower production costs. Therefore, it is widely used in many industries. The specific core automatic packaging principle is as follows: the bag opening is manually secured to the discharge pipe, and then the four corners of the bag are hung on the bag hanging mechanism. After the bag opening is clamped by the clamping mechanism, the material reaches the bag opening through the discharge pipe and enters the bag. When the weighing device detects that the weight of the material inside the bag reaches the set value, the feeding stops, completing the precise filling work. After filling, the restraints on the bag opening and four corners are released, and the bag automatically falls to the conveying device, completing the entire packaging process, as disclosed in the semi-automatic vertical spiral ton packaging equipment for powder with application number 202122060819.5.

[0003] However, while the aforementioned document includes a swing mechanism to drive the bag-hanging mechanism for easier bag hanging, the range of motion is fixed. If the bag size is too large, the swing range may still be insufficient for the operator to hang the bags at all four corners from the same position. The operator may still need to move their body, albeit within a smaller range than with traditional setups. Furthermore, a distance remains between adjacent bag-hanging mechanisms after the swing, and the bag is also affected by the preceding bag-hanging mechanism when hanging it between the inner and outer mechanisms. Therefore, this device requires a certain level of physical strength and operational skill from the operator, thus increasing labor costs. Summary of the Invention

[0004] One of the objectives of this application is to solve the problem that operators cannot operate from their original positions when the bag is suspended at the four top corners by the bag hanging mechanism in the current market lifting screw ton packaging device, and to provide a lifting screw ton packaging device.

[0008] Preferably, the clamping mechanism includes symmetrically arranged clamping arms, which are connected in the middle by a clamping cylinder, and a clamping block is provided at the top of the clamping arm for clamping the bag opening of the packaging bag to the outside of the dispensing component. Preferably, the feeding assembly includes a fixed plate and a feeding cylinder. The fixed plate is installed at the center above the top plate, and the feeding cylinder is arranged in the middle of the fixed plate. Four push cylinders are distributed in a rectangular shape at the bottom of the fixed plate. The receiving assembly includes a movable plate and a receiving pipe. The top of the movable plate is connected to the bottom of the push cylinders, and a receiving pipe is arranged at the top of the movable plate. The receiving pipe engages with the inside of the feeding cylinder, and a sealing rubber is detachably installed on the outside of the receiving pipe. The bottom of the receiving pipe is detachably installed with the top of the telescopic pipe.

[0009] Preferably, the discharge assembly includes a first connecting plate, a second connecting plate, and a discharge cylinder. The first connecting plate and the second connecting plate are arranged vertically and connected in the middle by the discharge cylinder. The bottom of the discharge cylinder protrudes from the second connecting plate. The top of the discharge cylinder is detachably installed from the bottom of the telescopic pipe. Tension sensors are installed at the four corners of the top of the first connecting plate, and the top of the tension sensors is installed at the bottom of the telescopic cylinder. The telescopic cylinder is installed on the outside of the fixed plate.

[0010] Preferably, a rotating assembly is provided on the outside of the feeding cylinder located between the first connecting plate and the second connecting plate. The rotating assembly includes a drive gear, a rotating gear, a rotating cylinder, and a rotating ring. The rotating gear is coaxially connected to the bottom of the rotating cylinder, and a rotating ring is provided at the bottom of the rotating gear and the top of the rotating cylinder. The rotating ring at the bottom of the rotating gear is connected to the upper bearing of the second connecting plate, and the rotating ring at the top of the rotating cylinder is connected to the bottom bearing of the first connecting plate. A drive gear is provided on the outside of the rotating gear to mesh with it, and the bottom of the drive gear is driven by a control motor.

[0011] Preferably, four rotating arm assemblies are distributed at equal angles on the outside of the rotating cylinder. Each rotating arm assembly includes a rotating arm rod, a reserved groove is provided at the top end of the rotating arm rod, and circular reserved holes are evenly distributed on the top side wall of the rotating arm rod. A locking pin is provided in the middle of the reserved hole.

[0012] Preferably, the sliding seat includes a connecting cover, a slider, a return spring, an intermediate plate, and a control cylinder. The connecting cover is U-shaped and engages with the outside of the rotating arm. A slider is provided in the middle of the connecting cover and slides in a reserved groove.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: (1) The rotating arm assembly can rotate to work. When the rotating arm assembly rotates, the hook assembly above it will also rotate. Therefore, when the operator rotates the four top corners of the packaging bag with the hook assembly, the operator does not need to frequently move his / her body position. He / she only needs to stand in a fixed position to hang the four top corners of the packaging bag on the hook assembly in turn. This greatly reduces the time for the operator to move and adjust his / her body during the hanging process, thereby significantly improving the hanging efficiency. It ensures that each hook assembly can be in the position closest to the operator to hang the packaging bag. Throughout the process, the operator is always in a relatively comfortable position, reducing the risk of occupational diseases caused by excessive labor intensity. The work is more relaxed and comfortable and safer.

[0015] (2) The hook assembly can also move on the rotating arm through the sliding seat. Therefore, when hanging packaging bags, the operator can move the hook assembly to a suitable position under the action of the sliding seat according to his height. This makes the operation of the equipment not limited by the height of the operator. As a result, when the equipment is used in the workshop, the personnel can move flexibly when the various devices are operated, which improves the versatility and mobility of the equipment, reduces the labor cost of workshop use, and makes the design of the whole device more humanized.

[0016] (3) A graded feeding assembly is set at the bottom of the feeding hopper. The design of multiple detachable cylinders makes it more convenient to clean and maintain the feeding assembly later. If a cylinder is damaged or malfunctions, it can be quickly replaced without replacing all the feeding assemblies. This not only reduces maintenance time and cost, but also improves the availability and reliability of the equipment. Attached Figure Description

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] One preferred embodiment of this application, such as Figures 1 to 12 As shown, a lifting spiral ton packaging device includes a conveying unit 1 for conveying packaging bags and packaged products. A support unit 2 is provided on one side of the conveying unit 1. A climbing ladder 3 is provided on one side of the conveying unit 1, and a work platform 4 is provided on the other side. A feeding bin 5 is provided at the top of the support unit 2, and a spiral conveying assembly is provided inside the feeding bin 5 for feeding. A grading and discharging assembly is provided at the bottom of the feeding bin 5 for continuous product discharging. The grading and discharging assembly includes a discharging assembly 8 connected to the bottom of the feeding bin 5, a receiving assembly 11 connected by a pushing cylinder 10, and a extending assembly 8. The air cylinder 9 is connected to the discharge assembly 13 and the telescopic pipe 12. The discharge assembly 8, receiving assembly 11, telescopic pipe 12 and discharge assembly 13 are arranged in order from top to bottom. The bottom of the discharge assembly 13 is provided with a clamping mechanism 6 for clamping the opening of the packaging bag. The middle of the discharge assembly 13 is also provided with a rotating arm assembly 15 connected by a rotating assembly 14. The outside of the rotating arm assembly 15 is provided with a hook assembly 18 connected by a sliding seat 17. The hook assembly 18 is used to suspend the hanging straps at the four top corners of the packaging bag. The outside of the feeding hopper 5 is also provided with a blower 7 for inflation.

[0034] This application provides a lifting spiral ton packaging device. Specifically, the packaging bag to be packaged is conveyed by the conveying unit 1. The operator stands above the work platform 4. When the packaging bag arrives at the operator's position with the conveying unit 1, the operator first clamps the bag opening with the bottom of the discharge component 13. Then, the clamping mechanism 6 clamps the bag opening with the bottom of the discharge component 13. After that, the control of the rotating component 14 can make the rotating arm component 15 rotate. When the rotating arm component 15 rotates, it can drive the hook component 18 connected to its bottom through the sliding seat 17 to rotate, thereby completing the purpose of rotating the four top corners of the packaging bag with the hook component 18. When rotating, the rotating component 14 can rotate in both directions. For example, when rotating in the forward direction, the two hook components 18 on one side are used to hang the packaging bag. When rotating in the reverse direction, the other two hook components 18 are used to hang the packaging bag, ensuring that the packaging bag is not excessively twisted. Next, the blower 7 is started, causing it to feed material into the packaging bag through the feeding hopper 5 and the grading and discharging assembly. Then, the external spiral feeding device tilts and transports the product into the feeding hopper 5. The spiral conveying assembly inside the feeding hopper 5 is then started to transport the product. During the product transport, the product passes through the grading and discharging assembly and finally reaches the inside of the packaging bag. When the product is being discharged, the telescopic cylinder 9 is activated, causing the loaded packaging bag to rise through the tension sensor 16. When the tension sensor 16 reaches a fixed value, feeding stops, and the telescopic cylinder 9 is controlled to descend, causing the loaded packaging bag to fall above the conveying unit 1. The above work is repeated, causing the hook assembly 18 and the clamping mechanism 6 to release the limits on the bag opening and the four sides of the packaging bag. Thus, the conveying unit 1 continues to start, transporting new packaging bags to the operator's position for bagging. The bagged packaging bags are then output, achieving the purpose of automated transportation.

[0035] When the material is fed through the graded feeding assembly, the cylinder 10 is first in a retracted state. At this time, the top of the receiving assembly 11 is connected to the bottom of the feeding assembly 8. Therefore, after the raw material inside the feeding hopper 5 falls, it enters the feeding assembly 8 and then reaches the receiving assembly 11. Since the bottom of the receiving assembly 11 is connected to the telescopic pipe 12, the product enters the telescopic pipe 12 and then reaches the discharge assembly 13. The product is then discharged through the discharge assembly 13 and enters the packaging bag.

[0036] Specifically, according to Figure 1As shown, the conveying unit 1 includes a support frame 101, conveying rollers 102 and a drive assembly 103. The top of the support frame 101 is evenly distributed with conveying rollers 102, and adjacent conveying rollers 102 are connected by chains and sprockets. The top of one of the conveying rollers 102 is driven and controlled by the drive assembly 103.

[0037] When the conveying unit 1 is working, the drive assembly 103 needs to be started so that it can drive a conveying roller 102 and its external sprocket to rotate. In conjunction with the chain conveying work, each conveying roller 102 will rotate. Thus, under the action of each rotating conveying roller 102, the continuous conveying of packaging bags can be completed.

[0038] Among them, according to Figure 1 and 3 As shown, the support unit 2 includes support rods 21, a top plate 22, and guardrails 23. There are four rectangular support rods 21. The top plate 22 is located slightly above the top of the four support rods 21. Guardrails 23 are provided on the top of the top of the top plate 22 in three directions for protection. The top of the top plate 22 is provided with a feeding hopper 5. The bottom of the feeding hopper 5 can be disassembled and installed with respect to the unloading assembly 8.

[0039] The guardrail 23 is designed to ensure the safety of operators when they climb ladder 3 to reach the top plate 22 for maintenance of the feed hopper 5.

[0040] Furthermore, according to Figure 5 and Figure 6 As shown, the clamping mechanism 6 includes symmetrically arranged clamping arms 63, and the middle of the symmetrically arranged clamping arms 63 is connected by a clamping cylinder 61. A clamping block 62 is provided at the top of the clamping arm 63 for clamping the bag opening of the packaging bag to the outside of the discharge component 13.

[0041] Specifically, when the bag opening is manually placed on the bottom of the discharge assembly 13, the clamping cylinder 61 is controlled to drive the five clamping arms 63 to move towards each other. This causes the clamping block 62 at the top of the clamping arm 63 to move towards the position of the discharge assembly 13. Then, through the engagement between the arc-shaped structure at its top and the outside of the discharge assembly 13, the bag opening can be clamped.

[0042] As a further preferred embodiment, according to Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the feeding assembly 8 includes a fixed plate 81 and a feeding cylinder 82. The fixed plate 81 is installed at the center above the top plate 22, and the feeding cylinder 82 is arranged in the middle of the fixed plate 81. Four push cylinders 10 are distributed in a rectangular shape at the bottom of the fixed plate 81. The receiving assembly 11 includes a movable plate 111 and a receiving pipe 112. The top of the movable plate 111 is connected to the bottom of the push cylinder 10, and the receiving pipe 112 is arranged at the top of the movable plate 111. The receiving pipe 112 is engaged with the inside of the feeding cylinder 82, and a sealing rubber is detachably installed on the outside of the receiving pipe 112. The bottom of the receiving pipe 112 is detachably installed with the top of the telescopic pipe 12.

[0043] The discharge assembly 13 includes a first connecting plate 131, a second connecting plate 132, and a discharge cylinder 133. The first connecting plate 131 and the second connecting plate 132 are arranged vertically and connected in the middle by the discharge cylinder 133. The bottom of the discharge cylinder 133 protrudes from the second connecting plate 132. The top of the discharge cylinder 133 is detachably installed from the bottom of the telescopic pipe 12. Tension sensors 16 are installed at the four corners of the top of the first connecting plate 131, and the top of the tension sensors 16 is installed with the bottom of the telescopic cylinder 9. The telescopic cylinder 9 is installed on the outside of the fixed plate 81.

[0044] Specifically, when the product inside the feeding hopper 5 is unloaded, it will fall into the receiving pipe 112 in the middle of the movable plate 111, and then through the receiving pipe 112 to the inside of the telescopic pipe 12. After that, it will reach the inside of the discharge cylinder 133 through the telescopic pipe 12 and then be discharged.

[0045] When the graded feeding component malfunctions or needs cleaning, the operator can activate the telescopic cylinder 9 and the push cylinder 10 as needed. When the telescopic cylinder 9 descends, it will drive the first connecting plate 131, the second connecting plate 132 and the discharge cylinder 133 to descend. When the push cylinder 10 descends, it will separate the receiving pipe 112 from the discharge cylinder 82, thereby causing the receiving pipe 112 and the telescopic pipe 12 to descend together. Once they have descended to the appropriate position, the operator can easily disassemble and clean them. Furthermore, in this application, the connection between the various cylinders can be a flange connection. At the same time, those skilled in the art can also make any selections according to their needs or convenience, and the present invention does not impose any restrictions on this.

[0046] As a further preferred embodiment, according to Figure 5 , Figure 7 , Figure 9 and Figure 11As shown, a rotating assembly 14 is provided on the outside of the feeding cylinder 82 located between the first connecting plate 131 and the second connecting plate 132. The rotating assembly 14 includes a drive gear 141, a rotating gear 142, a rotating cylinder 143, and a rotating ring 144. The rotating gear 142 is coaxially connected to the bottom of the rotating cylinder 143. A rotating ring 144 is provided at the bottom of the rotating gear 142 and at the top of the rotating cylinder 143. The rotating ring 144 at the bottom of the rotating gear 142 is connected to the upper bearing of the second connecting plate 132. The rotating ring 144 at the top of the rotating cylinder 143 is connected to the bottom bearing of the first connecting plate 131. The drive gear 141 is provided on the outside of the rotating gear 142 and meshes with it. The bottom of the drive gear 141 is driven by a control motor.

[0047] The rotating cylinder 143 has four rotating arm assemblies 15 distributed at equal angles on its exterior. Each rotating arm assembly 15 includes a rotating arm rod 151. A reserved groove 152 is provided at the top end of the rotating arm rod 151, and circular reserved holes 153 are evenly distributed on the top side wall of the rotating arm rod 151. A locking limit pin 154 is provided in the middle of the reserved hole 153.

[0048] The sliding seat 17 includes a connecting cover 171, a slider 172, a return spring 173, an intermediate plate 174, and a control cylinder 175. The connecting cover 171 is U-shaped and engages with the outside of the rotating arm 151. The slider 172 is provided in the middle of the cover and slides in the reserved groove 152. The return spring 173 is provided on the outside of the slider 172 and is connected to one side of the inner wall of the reserved groove 152. The intermediate plate 174 is fixed to one side of the bottom of the connecting cover 171, and the control cylinder 175 is provided on the inner side of the intermediate plate 174 and is connected to the hook assembly 18.

[0049] The hook assembly 18 includes a rotating shaft 181, a rotating hook 182, and a limiting block 183. The rotating shaft 181 is installed inside the connecting cover 171 at a slightly lower position, and is connected to the rotating hook 182 in the middle. The top end of the rotating hook 182 is axially connected to the top end of the control cylinder 175. The bottom end of the rotating hook 182 is restricted and closed by the limiting block 183, and the limiting block 183 is fixed to the bottom of the intermediate plate 174.

[0050] When the operator connects the four corners of the packaging bag to the hook assembly 18, for ease of operation, the control motor can be activated, causing the drive gear 141 at its top to rotate. The rotation of the drive gear 141 then drives the rotating gear 142 to rotate, which in turn causes the rotating cylinder 143 to rotate the rotating arm 151. This allows the rotating arm 151 to rotate to a position in front of the operator. Then, according to the operator's needs, the handle at the top of the connecting cover 171 can be grasped to control the connection. The connecting cover 171 slides outward under the action of the slider 172, thereby moving the hook assembly 18 connected to its bottom. When the hook assembly 18 moves to the appropriate position, the control cylinder 175 at the top of the intermediate plate 174 can be activated, causing the rotating hook 182 to rotate. When the rotating hook 182 rotates, it will separate from the limiting block 183. At this time, the hanging and detaching of the four top straps of the packaging bag can be performed. Afterward, the control cylinder 175 resets, so that the top tube of the rotating hook 182 is limited and sealed by the limiting block 183. Then, the operator releases the limiting of the connecting cover 171. At this time, the return spring 173 resets, causing the entire connecting cover 171 to move and reset inside the reserved groove 152. When it resets to the position blocked by the limiting pin 154, it reaches the initial position. Then, the limiting pin 154 limits the positions of the two sides of the slider 172.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
