Description

Technical Field

[0001] This invention belongs to the field of bagging machine technology, specifically relating to an automatic aluminum-shell bagging machine. Background Technology

[0002] Aluminum shell bagging machines are automated or semi-automated equipment specifically designed for packaging aluminum shells. These machines include fully automatic models that integrate feeding, bagging, and sealing, as well as semi-automatic models that require manual assistance in bagging and are filled by the equipment. They mainly serve the downstream packaging process in industries such as electronic components and hardware products.

[0003] Current bagging machines have complex overall structures, with intricate interrelationships between their transmission, control, and execution modules. This places high demands on processing precision and assembly techniques, significantly increasing manufacturing difficulty. Due to this complexity, material and processing costs are high. During operation, if a malfunction occurs, maintenance personnel struggle to quickly locate the problem, and disassembly and replacement of parts are difficult, often requiring extended downtime for repairs, severely impacting production efficiency. Furthermore, in the aluminum shell pushing and packaging stage, existing equipment typically uses a pushing mechanism to directly insert the aluminum shell into the heat shrink bag. During this process, the edges of the aluminum shell easily scrape against the bottom opening of the heat shrink bag. Given the soft material of the heat shrink bag, the bottom opening is prone to curling, folding, or even flipping under the pushing force, causing the heat shrink bag to lose its normal opening shape. This results in the aluminum shell failing to be inserted smoothly or the bag opening being uneven after insertion, ultimately leading to packaging failure. Therefore, the overall adaptability is poor, and the limitations are significant.

[0004] Therefore, it is necessary to provide an automatic aluminum-shell bagging machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic aluminum shell bagging machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic aluminum shell bagging machine, comprising a support plate and a feeding plate; a pusher is provided on the support plate to horizontally push the aluminum shell towards the feeding plate; a spreading assembly is provided on both sides of the support plate to limit the aluminum shell and spread the heat shrink bag; a pressing assembly is also provided between the support plate and the feeding plate to press down and limit the end of the heat shrink bag; a pressing component is also provided on the feeding plate; and a sliding hot pressing component is provided on the outer side of the support plate and the feeding plate.

[0007] As a preferred technical solution of the present invention, two sets of lead screw slides are symmetrically distributed on both sides of the material support plate, and each lead screw slide has a slider. The spreading component is installed on the slider of the lead screw slide and moves synchronously with the slider.

[0008] As a preferred technical solution of the present invention, the spreading assembly includes a double-rod cylinder mounted on the slider and a support plate fixed to the inner side of the double-rod cylinder. Two support plates are provided and arranged vertically. The double-rod cylinder adjusts the vertical width of the support plate by extending and retracting.

[0009] As a preferred technical solution of the present invention, the pressing assembly is disposed between two sets of support plates. The pressing assembly includes a pressing plate for pressing and limiting the lower side of the port of the heat shrink bag after it is opened, and a pressing cylinder for driving the pressing plate to rise and fall. The two ends of the pressing plate are respectively attached to the opposite side surfaces of the two sets of support plates. The bottom end of the pressing plate is inclined towards the feeding plate and presses and limits the lower side of the heat shrink bag on the feeding plate after it is opened.

[0010] As a preferred technical solution of the present invention, a transmission assembly is provided on both sides of the bagging position of the feeding plate. The transmission assembly includes a rotating wheel 1 and a rotating wheel 2 respectively disposed on the outer side of the two side support plates. A shaft extending downward and penetrating the feeding plate is fixed at the center of the rotating wheel 1 and the rotating wheel 2. A horizontal elongated hole for the shaft to pass through is opened on the feeding plate. The inner width of the elongated hole is equal to the outer diameter of the shaft, and the shaft can slide horizontally along the elongated hole.

[0011] As a preferred technical solution of the present invention, a servo motor is installed below the feeding plate, and a drive wheel is installed at the output end of the servo motor. Synchronous wheels are provided on both sides of the drive wheel. A synchronous belt is sleeved between the drive wheel and the synchronous wheels. The synchronous wheel on one side drives the rotating wheel to rotate through the shaft, while a columnar body is fixed on the top surface of the synchronous wheel on the other side. A drive gear is fixed on the columnar body. A transmission gear is fixed at the bottom end of the shaft of the rotating wheel and meshes with the drive gear.

[0012] As a preferred technical solution of the present invention, bearings are sleeved on the shaft of the rotating wheel and on the synchronous wheel with the columnar body, and an adjusting rod extending horizontally toward the servo motor is fixed outside the bearing; a push plate is provided above the synchronous belt, and the two sides of the push plate abut against the ends of the two adjusting rods.

[0013] As a preferred technical solution of the present invention, a connecting plate is fixed on the corresponding adjusting rod, passing over the drive gear plate and sleeved on the rotating wheel shaft through the bearing at its end. The side of the push plate that contacts the adjusting rod is an inclined surface, and the adjusting rod moves outward when the push plate pushes towards the outer end of the feeding plate. A transverse groove is opened on the adjusting rod, and a rod body moves through the transverse groove. The top of the rod body is fixed to the bottom end face of the feeding plate.

[0014] As a preferred technical solution of the present invention, a tensioning wheel for tensioning the synchronous belt is rotatably connected below the push plate. When the push plate moves the adjusting rod outward, the tensioning wheel moves inward to the inside of the synchronous belt to increase the horizontal length of the synchronous belt, thereby compensating for the displacement of the synchronous pulleys on both sides. Conversely, when the push plate returns to its original position, the tensioning wheel pulls the synchronous belt back, shortening the horizontal length of the synchronous belt and pulling the synchronous pulleys on both sides back, ensuring that the adjusting rod is always in close contact with the inclined surface of the push plate.

[0015] As a preferred technical solution of the present invention, a vertical plate is fixed below the feeding plate, and a tension spring is fixed between the vertical plate and the push plate. A moving groove is provided on the push plate, and a slot is provided on the inner wall of one side of the moving groove. A drive shaft is connected to the output end of the servo motor, and a slot is provided at an equal angle on the outer wall of the drive shaft. A locking block connected to the slot is provided in the slot, and a spring is fixed between the locking block and the slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, an automated bagging process for aluminum shells is achieved through a simplified mechanical structure, significantly reducing the number of overall parts and clarifying the linkage between various actuators. This reduces the processing and assembly difficulty of the entire machine, ensuring consistency and stability of the equipment. Simultaneously, material and processing costs are effectively controlled, and the assembly and debugging cycle is shortened. During equipment operation, the simple structure and clearly defined functions of each component significantly reduce potential failure points. Even if an anomaly occurs, maintenance personnel can quickly identify the problem and disassemble or replace it, effectively shortening downtime for maintenance. In the aluminum shell pushing and packaging stage, this invention clamps and limits the opening of the heat-shrink bag, ensuring the bag opening remains stably open during aluminum shell insertion. The bag opening position does not shift with the pushing action, preventing scratching or pulling due to contact between the aluminum shell and the bag opening. This effectively prevents curling, folding, or flipping of the bottom opening of the heat-shrink bag, maintaining flatness under clamping and limiting action. Overall, the reliability of operation is high, and the packaging effect is stable. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see Figures 1 to 4 This invention provides an automatic aluminum shell bagging machine, which mainly achieves automatic bagging of aluminum shells through a simplified mechanical structure, reducing the processing and assembly difficulty of the whole machine. The automatic aluminum shell bagging machine includes a support plate 1 and a feeding plate 5. A pusher 2 is provided on the support plate 1 to horizontally push the neatly stacked aluminum shells towards the feeding plate 5. Simultaneously, a spreading assembly 4 is provided on both the left and right sides of the support plate 1 to limit the aluminum shells and open the heat shrink bags. After feeding, the spreading assembly 4 retracts horizontally away from the feeding plate 5 along the support plate 1. A pressing assembly is also provided between the support plate 1 and the feeding plate 5 to press down and limit the ends of the heat shrink bags before pushing the material. The pressing assembly also guides the aluminum shells transferred from the support plate 1 to the feeding plate 5. A pressing component 3 is also provided on the feeding plate 5, which can press down the heat shrink bags after aluminum shell packaging and facilitate sealing. A hot pressing component 6, which slides in the left-right direction, is provided on the outer sides of the support plate 1 and the feeding plate 5 to seal the ends of the packaged heat shrink bags.

[0045] In the above structure, the pusher 2 includes a long-stroke cylinder and a plate installed at the end of the long-stroke cylinder, so as to ensure that the aluminum shell is pushed into the heat shrink bag; the pressing component 3 includes a support frame plate fixed on the feeding plate 5, a short-stroke cylinder on the support frame plate, and a plate at the end of the short-stroke cylinder to press the port of the heat shrink bag.

[0046] Furthermore, refer to Figure 1 Two sets of screw slides 101 are fixedly installed on the left and right sides of the material support plate 1, and each screw slide 101 has a slider. The expansion assembly 4 is installed on the slider of the screw slide 101 and moves synchronously with the slider.

[0047] Furthermore, after the aluminum shell completes the automatic bagging, the expansion assembly 4 retracts entirely onto the receiving plate 1. At this time, the pressing component 3 activates to press the ends of the heat shrink bag, and then the heat pressing component 6 works to seal the ends of the heat shrink bag; whereby... Figure 1 The hot press component 6 is operated manually. In practical applications, the hot press component 6 can also be changed to automatic operation. The hot press component 6 is an existing mature technology and will not be described in detail here.

[0048] In the above structure, refer to Figure 2 The expansion assembly 4 includes a double-rod cylinder 402 fixedly mounted on the slider, and a support plate 401 fixed on the inner side of the double-rod cylinder 402. There are two support plates 401 arranged vertically. When the double-rod cylinder 402 retracts, the two support plates 401 move in opposite directions. At this time, the vertical width of the two support plates 401 narrows, which facilitates the placement of the heat shrink bag. After the heat shrink bag reaches the designated position, the vertical width of the two support plates 401 widens by extending the double-rod cylinder 402, thus expanding the heat shrink bag.

[0049] Furthermore, refer to Figures 1 to 3 The edge pressing assembly is set between the left and right support plates 401. The edge pressing assembly includes a pressure plate 501 and an edge pressing cylinder 502 that drives the pressure plate 501 to rise and fall. The pressure plate 501 is used to press down the lower side of the port after the heat shrink bag is opened. A support block (not shown in the figure) is also fixed below the feeding plate 5 to support the edge pressing cylinder 502.

[0050] It is important to note that the left and right ends of the pressure plate 501 are respectively attached to the opposite surfaces of the left and right sets of support plates 401, ensuring that the opening of the heat shrink bag is horizontally and vertically aligned, thus enabling the aluminum shell to be stably pushed into the packaging. Simultaneously, to prevent the pressure plate 501 from obstructing the aluminum shell and affecting its normal pushing, the horizontal plane of the support plate 1 should be higher than the horizontal plane of the loading plate 5, and there should be a height difference between the two, with them being separate. When the heat shrink bag is not pressed down, the top of the pressure plate 501 is higher than the top horizontal plane of the support plate 1. After the heat shrink bag is pressed down and limited, one side of the top of the pressure plate 501 is flush with and overlaps the end of the support plate 1, while the other side is attached to the top of the loading plate 5. At this time, the aluminum shell can be smoothly moved into the opened heat shrink bag via the support plate 1 and the pressure plate 501. (Refer to...) Figure 4 The bottom end of the pressure plate 501 is tilted towards the feeding plate 5, and the lower side of the heat shrink bag on the feeding plate 5 is pressed down and limited. The pressure plate 501 converts the height difference between the supporting plate 1 and the feeding plate 5 into a smooth slope, ensuring that the normal pushing of the aluminum shell is not affected.

[0051] During the feeding of the heat shrink bag, the heat shrink bag is manually pulled to fit onto the support plate 401. Then the support plate 401 opens the heat shrink bag, and the heat shrink bag is continuously pulled toward the pressure plate 501. At this time, there is a gap between the pressure plate 501 and the support plate 1, which allows the heat shrink bag to fit. When the lower side of the heat shrink bag moves into the gap between the two after it is opened, the lower side of the heat shrink bag is clamped by pressing down with the pressure plate 501.

[0052] In summary, in the automatic bagging of aluminum shells, the heat shrink bag is first manually placed on the support plate 401, and then the support plate 401 opens the heat shrink bag. At the same time, the support plate 401 can also position the aluminum shell. Then, the pressure plate 501 presses down and flattens the lower side of the opened heat shrink bag. Next, the pusher 2 pushes the aluminum shell into the heat shrink bag. After packaging, the opening component 4 is returned, and the heat shrink bag is first limited by the pressing component 3. Then, the sealing operation is achieved by the heat pressing component 6. In this process, the number of parts is small, and the linkage between each actuator is clear, which reduces the processing and assembly difficulty of the whole machine and helps to ensure the consistency and stability of the equipment.

[0053] Example 2:

[0054] Please see Figure 1 , Figure 3 , Figure 5 Based on Embodiment 1, in order to realize the automatic feeding of heat shrink bags to the pressing assembly, the position near the end of the feeding plate 5 is improved: a transmission assembly 7 is added on both sides of the bag-covering position of the feeding plate 5. When the heat shrink bag is covered on the support plate 401 of the spreading assembly 4, the transmission assembly 7 rotates and contacts both sides of the heat shrink bag. Through the friction generated between the two, the heat shrink bag is transmitted between the pressing assembly and the feeding plate 5. Then, with the help of the pressing assembly, the lower end of the heat shrink bag is limited.

[0055] Furthermore, refer to Figure 5 The transmission component 7 includes a first rotating wheel 701 and a second rotating wheel 704 respectively disposed on the outer sides of the left and right support plates 401. When the heat shrink bag is fitted onto the support plate 401, the first rotating wheel 701 is located on the left side of the heat shrink bag, while the second rotating wheel 704 is located on the right side of the heat shrink bag. The outer walls of both have uneven points or are fitted with rough rubber sleeves to ensure friction with the heat shrink bag and realize the transmission of the heat shrink bag (the specific roughness setting can be adjusted according to the actual transmission effect). The center of the first rotating wheel 701 and the second rotating wheel 704 is fixed with a shaft extending downward and penetrating through the feeding plate 5. A horizontal elongated hole is opened on the feeding plate 5 for the shaft to pass through. The inner width of the elongated hole is equal to the outer diameter of the shaft, and the shaft can slide horizontally along the elongated hole.

[0056] Furthermore, refer to Figure 3 and Figure 5A servo motor 707 is fixedly installed below the feed plate 5, and a drive wheel 708 is fixedly installed at the output end of the servo motor 707. Synchronous pulleys 702 are provided on both the left and right sides of the drive wheel 708. A synchronous belt 703 is sleeved between the drive wheel 708 and the synchronous pulleys 702. The synchronous belt 703 enables the synchronous rotation of the drive wheel 708 and the synchronous pulleys 702. The synchronous pulley 702 on the left side is fixedly connected to the shaft of the rotating wheel 701. When the synchronous pulley 702 at this position rotates, it will drive the rotating wheel 701 to rotate in the same direction. The top surface of the synchronous wheel 702 on the right side is fixedly connected to the drive gear 706 via a columnar body (not shown in the figure). At the bottom end of the shaft of the second rotating wheel 704, a transmission gear 705 is fixed and meshes with the drive gear 706. When the synchronous wheel 702 on the right side rotates, it will drive the drive gear 706 to rotate in the same direction, while the drive gear 706 will drive the transmission gear 705 to rotate in the opposite direction. This makes the rotation direction of the second rotating wheel 704 opposite to that of the first rotating wheel 701, thus realizing the transmission of the heat shrink bag.

[0057] In the above structure, the timing pulley 702 and the drive pulley 708 must be sprockets, and the inner wall of the timing belt 703 has a groove for the sprockets to engage.

[0058] Compared to Embodiment 1, the transmission gear 705, drive gear 709, and synchronous wheel 702 enable the rotating wheel 701 and rotating wheel 704 to rotate in opposite directions. After the heat shrink bag is placed on the support plate 401, there is no need to manually pull the heat shrink bag to the edge pressing assembly. The frictional transport of rotating wheel 701 and rotating wheel 704 directly transfers the heat shrink bag to the edge pressing assembly, and the edge pressing assembly presses down below the opening of the heat shrink bag to achieve a limit, thereby improving work efficiency and avoiding potential safety hazards when manually pressing the edge of the heat shrink bag.

[0059] Example 3:

[0060] Please see Figures 6 to 10 Based on Embodiment 2, in order to make it easier to put the heat shrink bag onto the spreading assembly 4 in the early stage, the rotating wheel 1 701 and the rotating wheel 2 704 are configured to have the function of lateral adjustment; during the early bag putting process, the distance between the rotating wheel 1 701 and the support plate 401, and between the rotating wheel 2 704 and the support plate 401 are increased to facilitate the putting of the heat shrink bag. After the heat shrink bag is put on, the rotating wheel 1 701 and the rotating wheel 2 704 are adjusted back to their original positions to contact and drive the heat shrink bag.

[0061] Furthermore, refer to Figure 6 and Figure 7Bearings (not shown in the figure) are fitted on the shaft of the rotating wheel 701 and on the cylindrical body of the synchronous wheel 702 on the right side. The bearings are divided into inner and outer rings. The inner ring is fixed on the shaft of the rotating wheel 701 and the cylindrical body of the synchronous wheel 702 on the right side. The outer ring of the bearings at both locations is fixed with adjusting rods 801 that extend horizontally toward the servo motor 707. At the same time, due to the restriction of the bearings, the adjusting rods 801 will not be displaced in the vertical direction. In addition, a push plate 802 is provided above the synchronous belt 703. The two sides of the push plate 802 abut against the ends of the two adjusting rods 801, so that the synchronous wheel 702 is pressed against the inner wall of the synchronous belt 703, which not only satisfies the stable transmission between the synchronous wheel 702 and the synchronous belt 703, but also prevents the other synchronous wheel 702 from falling off.

[0062] Furthermore, a connecting plate 801a is fixed on the corresponding adjusting rod 801, passing over the drive gear 706 and sleeved on the shaft of the rotating wheel 704 via a bearing at its end (see details). Figure 6 and Figure 7 The side of the push plate 802 that contacts the adjusting rod 801 is an inclined surface. When the push plate 802 is pushed toward the outer end of the feeding plate 5, the adjusting rod 801 is moved outward. Continue to refer to Figure 6 and Figure 7 A transverse groove is provided on the adjusting rod 801, and a rod body (not shown in the figure) moves through the transverse groove. The top of the rod body is fixed to the bottom end face of the feeding plate 5. The rod body restricts the adjusting rod 801 to move outward in a horizontal direction only. When the adjusting rod 801 moves outward, one side of the adjusting rod 801 directly drives the rotating wheel 701 to move laterally to the outside of the feeding plate 5 through the bearing, while the other side of the adjusting rod 801 drives the rotating wheel 704 to move laterally to the outside of the feeding plate 5 through the connecting plate 801a. The shaft is restricted by the elongated hole to ensure that the rotating wheel 701 and the rotating wheel 704 move horizontally, thereby realizing the spacing adjustment.

[0063] Furthermore, refer to Figure 8 To ensure that the synchronous belt 703 always maintains transmission with the synchronous pulley 702, a tensioning pulley 805 for tensioning the synchronous belt 703 is rotatably connected below the push plate 802. When the push plate 802 moves the adjusting rod 801 outward, the tensioning pulley 805 moves inward to increase the horizontal length of the synchronous belt 703, thereby compensating for the displacement of the synchronous pulleys 702 on both sides. Conversely, when the push plate 802 returns to its original position, the tensioning pulley 805 also moves and pulls the synchronous belt 703 back, shortening its horizontal length and pulling the synchronous pulleys 702 on both sides back. This also ensures that the adjusting rod 801 is always in close contact with the inclined surface of the push plate 802.

[0064] Furthermore, refer to Figure 6 and Figure 9 Below the feeding plate 5, a vertical plate 503 is fixed. A tension spring 803 is fixed between the vertical plate 503 and the push plate 802. The tension spring 803 always provides a force that pulls the push plate 802 back toward the vertical plate 803. In order to push the adjusting rod 801 outward by the push plate 802, a moving groove 802a is provided on the push plate 802. A slot 802b is provided on the inner wall of one side of the moving groove 802a. A drive shaft 707a is connected to the output end of the servo motor 707 through a coupling (not shown in the figure). The outer wall of the drive shaft 707a has a slot at an equal angle (not shown in the figure). A locking block 707b connected to the slot 802b is provided in the slot. A spring 707c is fixed between the locking block 707b and the slot.

[0065] In the above structure, refer to Figure 10 The locking block 707b is tilted on one side. When the servo motor 707 rotates counterclockwise, it will drive the drive shaft 707a to rotate synchronously. The drive shaft 707a will push the locking block 707b against the slot 802b with its straight edge, and push the push plate 802 away from the vertical plate 503. When the servo motor rotates clockwise, the tilted surface of the locking block 707b will abut against the slot 802b. At this time, the locking block 707b will be squeezed into the slot and the spring 707c will be compressed. Before this, the locking block 707b will also provide some force to return the push plate 802. Under the action of the tension spring 803, the push plate 802 will be quickly brought back to its original position. After the push plate 802 returns to its original position, all the locking blocks 707b will no longer be in contact with the slot 802b, and the locking blocks 707b will be in an idle state, so they will not drive the push plate 802 to continue to push back.

[0066] It should be noted that the bagging process begins only after the servo motor 707 rotates counterclockwise and adjusts the first rotating wheel 701 and the second rotating wheel 702 laterally to increase the distance between the first rotating wheel 701 and the left support plate 401, and between the second rotating wheel 702 and the right support plate 401. After bagging is completed, the servo motor 707 rotates clockwise to decrease the distance between the first rotating wheel 701 and the left support plate 401, and between the second rotating wheel 702 and the right support plate 401, and the heat shrink bag is then transferred through the first rotating wheel 701 and the second rotating wheel 702.

[0067] Compared to Implementation 2, in the initial application of the heat shrink bag, the counterclockwise rotation of the servo motor 707 drives the push plate 802 and the adjusting rod 801 to move, thereby causing the rotating wheels 701 and 702 to move in opposite directions (i.e., increasing the distance between rotating wheel 701 and the left support plate 401, and between rotating wheel 702 and the right support plate 401). This avoids the problem of the distance between rotating wheel 701 and the left support plate 401, and between rotating wheel 702 and the right support plate 401 being too small, making it inconvenient to apply the heat shrink bag and improving the overall convenience of the operation.

[0068] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The automatic aluminum shell bagging machine according to claim 2, characterized in that: The opening assembly includes a double-rod cylinder mounted on a slider and a support plate fixed to the inner side of the double-rod cylinder. There are two support plates arranged vertically. The double-rod cylinder adjusts the vertical width of the support plate by extending and retracting.

4. The automatic aluminum shell bagging machine according to claim 3, characterized in that: The edge pressing assembly is disposed between two sets of support plates. The edge pressing assembly includes a pressure plate that presses down and limits the lower side of the port of the heat shrink bag after it is opened, and an edge pressing cylinder that drives the pressure plate to rise and fall. The two ends of the pressure plate are respectively attached to the opposite side surfaces of the two sets of support plates. The bottom end of the pressure plate is inclined towards the feeding plate and presses down and limits the lower side of the heat shrink bag on the feeding plate after it is opened.

5. An automatic aluminum-shell bagging machine according to claim 4, characterized in that: The feeding plate is equipped with a transmission assembly on both sides of the bagging position. The transmission assembly includes a rotating wheel 1 and a rotating wheel 2 respectively set on the outer side of the two side support plates. A shaft extending downward and penetrating the feeding plate is fixed at the center of the rotating wheel 1 and the rotating wheel 2. A horizontal elongated hole is opened on the feeding plate for the shaft to pass through. The inner width of the elongated hole is equal to the outer diameter of the shaft, and the shaft can slide horizontally along the elongated hole.

6. An automatic aluminum-shell bagging machine according to claim 5, characterized in that: A servo motor is installed below the feeding plate, and a drive wheel is installed at the output end of the servo motor. Synchronous wheels are provided on both sides of the drive wheel. A synchronous belt is sleeved between the drive wheel and the synchronous wheels. The synchronous wheel on one side drives the rotating wheel to rotate through the shaft, while a columnar body is fixed on the top surface of the synchronous wheel on the other side. A drive gear is fixed on the columnar body. A transmission gear is fixed at the bottom end of the shaft of the rotating wheel and meshes with the drive gear.

7. An automatic aluminum-shell bagging machine according to claim 6, characterized in that: Bearings are fitted on the shaft of the rotating wheel and on the synchronous wheel with the columnar body. Adjusting rods extending horizontally toward the servo motor are fixed outside the bearings. A push plate is provided above the synchronous belt, and the two sides of the push plate abut against the ends of the two adjusting rods.

8. An automatic aluminum-shell bagging machine according to claim 7, characterized in that: A connecting plate is fixed on the corresponding adjusting rod, passing over the drive gear plate and sleeved on the rotating wheel shaft by the bearing at its end. The side of the push plate that contacts the adjusting rod is an inclined surface. When the push plate is pushed toward the outer end of the feeding plate, the adjusting rod is moved outward. A transverse groove is opened on the adjusting rod, and a rod body moves through the transverse groove. The top of the rod body is fixed to the bottom end face of the feeding plate.

9. An automatic aluminum-shell bagging machine according to claim 7, characterized in that: Below the push plate, a tensioning wheel for tensioning the synchronous belt is rotatably connected. When the push plate moves the adjusting rod outward, the tensioning wheel moves inward to increase the horizontal length of the synchronous belt, thereby compensating for the displacement of the synchronous pulleys on both sides. Conversely, when the push plate returns to its original position, the tensioning wheel pulls the synchronous belt back, shortening its horizontal length and pulling the synchronous pulleys on both sides back, ensuring that the adjusting rod is always in close contact with the inclined surface of the push plate.
