Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a novel bagging device for packaging machines. Background Technology

[0002] Currently, when storing finished waterproof plugs, it is sometimes necessary to pack them into bags. In existing technologies, some waterproof plugs are packaged using a manual assembly line method. Specifically, the steps are as follows: Step 1: The waterproof plugs are manually counted and stacked, and then temporarily stored in the packaging area. Step 2: The waterproof plugs in the packaging area are transported to the bagging position. Step 3: The pre-processed packaging bags are taken, and the waterproof plugs are manually placed into the bags. Then, the bags are manually sealed.

[0003] In step three above, although unsealed packaging bags can be pre-processed, manual opening of the bag is required when manually filling the waterproof plugs, and manual assistance is needed to seal the bag after filling. This will affect the packaging efficiency of the waterproof plugs. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a novel bagging device for packaging machines to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A novel bag-filling device for a packaging machine includes a horizontally arranged frame. One end of the frame is detachably and rotatably connected to a bag-carrying shaft parallel to the width direction of the frame. The other end of the frame is equipped with two sets of oppositely arranged sealing, cutting, and supporting bag mechanisms that can move closer or further apart along the length direction of the frame. The frame is also equipped with a guide bag-feeding mechanism that can transport bags between the bag-carrying shaft and the two sets of sealing, cutting, and supporting bag mechanisms. Each sealing, cutting, and supporting bag mechanism includes a sealing assembly, a cutting assembly, and a supporting bag assembly.

[0006] Furthermore, each of the bag sealing assemblies includes a transverse plate parallel to the bag body bearing axis and mounted on the frame. A first heat-sealing knife is mounted on the opposite side of each of the two transverse plates, and a crossbar parallel to the first heat-sealing knife and mounted on the frame is provided above each of the transverse plates. Several second heat-sealing knives are equidistantly distributed and spaced apart along the length direction of the crossbar on the bottom surface of the crossbar.

[0007] Furthermore, each of the bag-supporting assemblies includes a support shaft that is parallel to the transverse plate and can reciprocate relative to the transverse plate along the length of the frame. The support shaft is located between the first heat-sealing knife and the second heat-sealing knife. Several rubber wheel shafts that are equidistantly distributed along the length of the support shaft and parallel to the support shaft are also installed on the opposite sides of the two support shafts. A support seat that is fixedly installed on the transverse plate is provided between every two adjacent rubber wheel shafts. The support seats are spaced apart from the support shafts, and a horizontally distributed movable plate that can be raised and lowered is provided above each support seat. The movable plates are located between two adjacent second heat-sealing knives, and vertically distributed bag-pressing plates are fixedly connected to the opposite ends of the movable plates.

[0008] Furthermore, each of the bag-cutting assemblies includes a cutting blade arranged parallel to the transverse plate and capable of reciprocating relative to the transverse plate along the length of the frame. The cutting blade is located between the second heat-sealing blade and the support shaft, and the cutting blade passes sequentially through the gap between the movable plate and the support seat.

[0009] Furthermore, one set of sealing and cutting bag-supporting mechanisms is fixedly installed on the frame, and another set of sealing and cutting bag-supporting mechanisms is slidably connected to the frame along the length of the frame. A telescopic component that can drive the sealing and cutting bag-supporting mechanism to reciprocate is connected to the other set of sealing and cutting bag-supporting mechanisms.

[0010] Furthermore, the telescopic assembly includes two fourth electric telescopic rods that can extend and retract synchronously. The two fourth electric telescopic rods are symmetrically installed on both sides of the frame along its length, and each fourth electric telescopic rod is parallel to the length of the frame. The telescopic end of each fourth electric telescopic rod is connected to the sealing and cutting bag support mechanism.

[0011] Furthermore, the frame is equipped with a limiting mechanism that restricts the extension length of the fourth electric telescopic rod.

[0012] Furthermore, the telescopic ends of the fourth electric telescopic rod are all connected to the sealing and cutting bag support mechanism through connecting plates. The limiting mechanism includes a threaded rod installed on the frame and arranged parallel to the fourth electric telescopic rod. The connecting plates are slidably sleeved on the threaded rods, and each threaded rod is threaded with a limiting block that can limit the extension length of the fourth electric telescopic rod.

[0013] Furthermore, the guiding bag conveying mechanism includes several guide shafts distributed along the length of the frame and capable of rotation. Each guide shaft is parallel to the bag body bearing shaft. One of the guide shafts is a drive shaft. A drive component is connected to the drive shaft. A bag clamping shaft is provided on the side of the drive shaft away from the bag body bearing shaft and is parallel to the drive shaft. Both ends of the bag clamping shaft are rotatably connected to the frame.

[0014] Furthermore, a ranging mechanism is installed on the frame located on the side of the drive shaft away from the bag clamping shaft. The ranging mechanism includes a U-shaped through-beam sensor and a ranging shaft installed on the frame. The ranging shaft is arranged parallel to the drive shaft, and one end of the ranging shaft is rotatably connected to the frame and driven by the drive shaft through a transmission mechanism. A ranging disk is coaxially installed on the other end of the ranging shaft. The edge of the ranging disk is located inside the U-shaped through-beam sensor, and multiple through holes are equally spaced along the circumference of the ranging disk at the edge position.

[0015] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, this invention guides and unwinds rolled bags via a bag-feeding mechanism until one end of the bag is positioned between two sets of sealing, cutting, and supporting bag mechanisms. Through the cooperation of these two mechanisms, the bag is first formed into a packaging bag using the sealing and cutting components. Then, the supporting bag component opens the bag until a set number of waterproof plugs are inserted. Finally, the sealing component closes the bag. This allows for automatic bag processing, as well as automatic bag opening and sealing, thus improving the packaging efficiency of waterproof plugs compared to manual methods.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figure 2 , Figures 12 to 19 As shown, this utility model provides a novel bagging device for packaging machines. Specifically, this utility model can be used as a component of an automatic packaging device. When the automatic packaging device is in use, a controller 1 and various sensors can be configured to automatically control the coordinated operation between the various mechanisms in the packaging device. Specifically, the controller 1 can be a PLC controller to realize the automatic packaging of waterproof plugs.

[0020] like Figures 1 to 19 As shown, the automatic packaging device includes a housing 5. Specifically, the housing 5 includes a load-bearing frame 51 with a frame structure, and multiple openable doors 52 are installed at various positions on the load-bearing frame 51. A horizontally arranged support platform 6 is installed inside the housing 5. A bagging device 2 is installed inside the housing 5 below the support platform 6. The bagging device 2 is the present invention. A conveying device 3 capable of transporting and counting materials horizontally is mounted on the top surface of the support platform 6. A receiving device 4 is provided below the discharge end of the conveying device 3 and between it and the bagging device 2. The receiving device 4 is vertically installed on the support platform 6 and passes through the support platform 6. The controller 1 is electrically connected to the bagging device 2, the conveying device 3, and the receiving device 4 respectively. Specifically, in use, the controller 1 can automatically control the coordinated operation between the bagging device 2, the conveying device 3, and the receiving device 4.

[0021] The receiving device 4 includes a receiving channel, on which an opening and closing mechanism 41 is installed, capable of automatically opening and closing the receiving channel. The opening and closing mechanism 41 is electrically connected to the controller 1. Specifically, in use, firstly, the waterproof plugs can be counted simultaneously while being transported to the packaging area by the conveying device 3; secondly, the receiving device 4 can temporarily store the counted waterproof plugs when the receiving channel is closed by the opening and closing mechanism 41; and when the number of waterproof plugs in the receiving channel reaches the set capacity value of the packaging bag, the conveying... Device 3 stops conveying; third, through the bagging device 2, when the receiving channel is opened by the opening and closing mechanism 41, the waterproof plug can be automatically put into the packaging bag and sealed to complete the packaging of the waterproof plug; thus, when the production volume of waterproof plugs is large, compared with the manual assembly line operation in the prior art, the automatic packaging device is more time-saving and labor-saving, thereby improving the packaging efficiency of waterproof plugs; in general, the automatic packaging device can realize the automatic packaging of waterproof plugs through the cooperation between various devices, so as to improve the packaging efficiency of waterproof plugs.

[0022] The specific configuration of the receiving device 4 is as follows: Figures 2 to 7As shown, the receiving device 4 penetrates the carrying platform 6 through the mounting port 61 opened on the carrying platform 6. The receiving device 4 includes a receiving hopper 42 that is vertically installed inside the machine housing 5 and has openings at both ends. The receiving hopper 42 is located below the discharge end of the conveying device 3, and the receiving hopper 42 has a receiving channel inside. The opening and closing mechanism 41 includes a first electric telescopic rod 411 and a first opening and closing plate 412. Specifically, the electric telescopic rod included in the automatic packaging device can be set as a telescopic cylinder. The first opening and closing plate 412 is located at the bottom opening of the receiving hopper 42 and is close to the receiving hopper 411. 2. A sliding connection is made, with the first electric telescopic rod 411 installed on the receiving hopper 42, and the telescopic end of the first electric telescopic rod 411 connected to the first opening and closing plate 412. The controller 1 is electrically connected to the first electric telescopic rod 411. Specifically, in the initial state, the telescopic end of the first electric telescopic rod 411 is in the extended state. At this time, the first opening and closing plate 412 can close the receiving channel in the receiving hopper 42. Then, when the telescopic end of the first electric telescopic rod 411 retracts, it can drive the first opening and closing plate 412 to move, so as to open the receiving channel in the receiving hopper 42.

[0023] Furthermore, such as Figure 2 , Figures 3 to 5 As shown, the bottom opening of the receiving hopper 42 is fixedly connected to a vertically distributed discharge pipe 43 to shorten the vertical distance between the bottom opening of the receiving hopper 42 and the opening of the packaging bag. A shaking mechanism capable of driving the receiving hopper 42 to rise and fall is installed inside the machine housing 5. Specifically, the shaking mechanism includes a support plate 44 horizontally installed on the discharge pipe 43. Both ends of the support plate 44 are connected to a second electric telescopic rod 45 vertically installed inside the machine housing 5 and capable of synchronous extension and retraction. The controller 1 is electrically connected to the second electric telescopic rod 45. Specifically, in the initial state, the telescopic end of the second electric telescopic rod 45 is in the extended state. When in use, after the receiving channel inside the receiving hopper 42 is opened by the opening and closing mechanism 41, the receiving hopper 42 can be shaken vertically by the repeated extension and retraction of the second electric telescopic rod 45, so that the waterproof plug inside the receiving hopper 42 can fall into the packaging bag through the discharge pipe 43.

[0024] Furthermore, such as Figure 3 and Figures 5 to 7As shown, a return pipe 46 with inclined distribution and open at both ends is provided on one side of the receiving hopper 42. The receiving device 4 also includes a bracket 47 installed in the housing 5. A distribution hopper 48 with vertical penetration through the bracket 47 and open at both ends is installed on the bracket 47. The distribution hopper 48 is located between the receiving hopper 42 and the discharge end of the conveying device 3. Two distribution plates 481 are provided at the bottom opening of the distribution hopper 48 to change the flow direction of the waterproof plug, whether it flows into the return pipe 46 or into the receiving hopper 42. The two distribution plates 481 are symmetrically distributed. All 1 are rotatably connected to the distribution hopper 48 via a horizontally set rotating shaft 482. The rotating shaft 482 is driven by a drive mechanism 49 mounted on the bracket 47 and electrically connected to the controller 1. The higher end of the return pipe 46 is connected to the distribution hopper 48. Specifically, in the initial state, when the bottoms of the two distribution plates 481 abut against each other, the bottom opening of the distribution hopper 48 can be closed. At the same time, one of the distribution plates 481 can close the opening of the higher end of the return pipe 46. At this time, when in use, the waterproof plugs after counting fall into the distribution hopper 48 for temporary storage.

[0025] While the conveying device 3 is conveying and counting the waterproof plugs, if the number of waterproof plugs falling into the distribution hopper 48 exceeds the set capacity of the packaging bag (e.g., the set capacity is 1000 plugs with an error margin of no more than 3 plugs), and the number of waterproof plugs falling into the distribution hopper 48 exceeds 1003 plugs, the distribution plate 481, which closes the higher end opening of the return pipe 46, can be rotated outward by the drive mechanism 49. After opening the higher end opening of the return pipe 46, another distribution plate can be used to... 481, the excess number of waterproof plugs flows into the return pipe 46 for return, and since the return pipe 46 is inclined, it is also convenient for the waterproof plugs to fall; if the number of waterproof plugs falling into the distribution hopper 48 is between 1000 and 1003, the drive mechanism 49 can rotate the other distribution plate 481 at the higher end of the unclosed return pipe 46 to make the waterproof plugs in the distribution hopper 48 fall into the receiving hopper 42, so that the number of waterproof plugs in each packaging bag can be controlled within the set error range.

[0026] The specific configuration of the drive mechanism 49 is as follows: Figure 3 , Figure 5 and Figure 6 As shown, each drive mechanism 49 includes a third electric telescopic rod 491 that is vertically mounted on the bracket 47 and electrically connected to the controller 1. The telescopic end of the third electric telescopic rod 491 is connected to one end of the rotating shaft 482 through a connecting rod structure 492. Specifically, in use, the telescopic movement of the third electric telescopic rod 491 can drive the rotating shaft 482 to rotate through the connecting rod structure 492, thereby driving the two material distribution plates 481 to rotate in both directions.

[0027] Furthermore, such as Figure 3 , Figure 5 and Figure 7 As shown, a second opening and closing plate 461 is slidably connected to the lower end of the return pipe 46. Specifically, in the initial state, the second opening and closing plate 461 can close the return channel inside the return pipe 46; while in use, by sliding the second opening and closing plate 461, the return channel inside the return pipe 46 can be opened so that the waterproof plug inside the return pipe 46 can drop material.

[0028] The specific configuration of conveyor device 3 is as follows: Figure 1 , Figure 2 , Figures 8 to 11 As shown, the conveying device 3 includes two sets of feed belt conveyors mounted side by side on the support platform 6. The two sets of feed belt conveyors have different widths. Specifically, since the feed belt conveyor with a larger width can convey a greater number of waterproof plugs within its width range than the feed belt conveyor with a smaller width, the feed belt conveyor with a smaller width is used as the fine-filling channel, and the other set of feed belt conveyors is used as the fast-feeding channel. Furthermore, each set of feed belt conveyors has a first baffle plate 33 installed on both sides along its length to prevent the waterproof plugs on the fine-filling channel and the fast-feeding channel from mixing together. The discharge end of each feeding belt conveyor is located above the receiving device 4. The other end of each feeding belt conveyor, i.e. the feeding end, is also equipped with vertically distributed material distribution plates 34. The two sides of the material distribution plate 34 are respectively connected to the first baffle plate 33, and the vertical distance between the bottom surface of the material distribution plate 34 and the top surface of the feeding belt conveyor is only allowed for one waterproof plug to pass through. Specifically, in use, when the waterproof plug passes through the gap between the material distribution plate 34 and the feeding belt conveyor, the waterproof plug can be spread out so that the waterproof plug is laid out in a single layer on the feeding belt conveyor.

[0029] A visual counting mechanism 39 is installed on the top surface of the support platform 6, opposite to the discharge end of the two sets of feeding belt conveyors. The controller 1 is electrically connected to the two sets of feeding belt conveyors and the visual counting mechanism 39. Specifically, the visual counting mechanism 39 can count the waterproof plugs that fall from the feeding belt conveyor after being laid out and unfolded by capturing images, and can transmit the image information to the controller 1. In use, assuming that the capacity of the packaging bag is set to 1000 pieces and the setting error is within 3 pieces, the relevant parameters can be set in the controller 1, and then the material is first fed by the fast feeding channel. It is assumed that the visual counting mechanism 39 counts the number of waterproof plugs falling from the conveyor. The number of waterproof plugs falling from the discharge end of position 3 is M. When M reaches about 800, the feeding speed of the fast feeding channel can be reduced, and feeding can continue. Then, when M reaches about 900, the feeding speed of the fast feeding channel is reduced again, and feeding continues until M reaches about 990, at which point the fast feeding channel stops. Then, the fine replenishment channel replenishes the material until M reaches the range of 1000 to 1003, at which point the fine replenishment channel stops. Compared with the manual counting method in the existing technology, this method not only facilitates the counting of waterproof plugs and improves counting efficiency, but also ensures that the number of waterproof plugs contained in each packaging bag is accurately controlled within the set error range.

[0030] Furthermore, such as Figure 8 , Figure 9 and Figure 11 As shown, the narrower feed belt conveyor is the first feed belt conveyor 31, and the other feed belt conveyor is the second feed belt conveyor 32. An adjustment mechanism 35 is installed above the first feed belt conveyor 31. The adjustment mechanism 35 includes a fixed plate 351 parallel to the width direction of the first feed belt conveyor 31. The fixed plate 351 is connected to the first baffle plate 33, and a slotted through hole 352 parallel to the fixed plate 351 is provided on the top surface of the fixed plate 351. Vertically distributed fastening bolts are also provided on the fixed plate 351. The fastening bolts slide through the slotted through hole 352 and pass through the fixed plate 351 before being threaded to a horizontal... Specifically, in the initial state, the top surface of the strip-shaped adjusting block 353 abuts against the bottom surface of the fixing plate 351, and the position of the strip-shaped adjusting block 353 can be fixed when the head of the fastening bolt abuts against the fixing plate 351. In use, one end of the strip-shaped adjusting block 353 abuts against the first baffle plate 33 located on one side of the first feeding belt conveyor 31, and there is a gap between the other end of the strip-shaped adjusting block 353 and the first baffle plate 33 located on the other side of the first feeding belt conveyor 31. At this time, the waterproof plug on the fine filling channel can only be fed through the gap between the strip-shaped adjusting block 353 and the first baffle plate 33.

[0031] When it is necessary to adjust the gap between the strip adjusting block 353 and the first baffle plate 33, after loosening the fastening bolt, the strip adjusting block 353 can be rotated and its position can be slid along the waist-shaped through hole 352 so that one end of the strip adjusting block 353 abuts against the first baffle plate 33 again. Then, the position of the strip adjusting block 353 is fixed by the fastening bolt. This allows the size of the gap between the strip adjusting block 353 and the first baffle plate 33 to be adjusted. For example, when the gap is large, two waterproof plugs can pass through the gap within the width range of the gap. When the gap is narrowed, the number of waterproof plugs that can pass through the gap within the width range is reduced to one. This allows the number of waterproof plugs that the fine-filling channel can deliver within the width range to be adjusted, making it easier to accurately count the waterproof plugs.

[0032] Furthermore, such as Figure 2 , Figure 8 and Figure 9 As shown, a recycling conveyor 36 is provided on the side of the first feeding belt conveyor 31 away from the second feeding belt conveyor 32. The recycling conveyor 36 serves as a recycling channel. The recycling conveyor 36 is arranged parallel to the feeding belt conveyor. A notch 331 is provided on the first baffle plate 33 to connect the first feeding belt conveyor 31 and the recycling conveyor 36. An adjusting mechanism 35 is installed at the notch 331. The controller 1 is electrically connected to the recycling conveyor 36. Specifically, the conveying direction of the recycling conveyor 36 is opposite to that of the feeding belt conveyor. In use, the waterproof plugs blocked by the strip adjusting block 353 on the fine filling channel can be guided by the strip adjusting block 353 and flow into the recycling channel through the notch 331. This not only prevents a large number of waterproof plugs from accumulating on the fine filling channel, but also facilitates the recycling of the waterproof plugs accumulated on the fine filling channel.

[0033] Furthermore, such as Figure 2 , Figure 8 and Figure 11 As shown, a feeding hopper 37 is installed above the feeding end of both sets of feeding belt conveyors. Specifically, the feeding hopper 37 can be vertically installed on the machine housing 5, and both the top and bottom ends of the feeding hopper 37 are open. The top opening of the feeding hopper 37 is also hinged with a hopper cover 371. In use, waterproof plugs can be added to both sets of feeding conveyor belts at the same time through the feeding hopper 37.

[0034] In addition, a return conveyor 38 is installed between the feed hopper 37 and the discharge end of the recycling belt conveyor 36. The return conveyor 38 is electrically connected to the controller 1. Specifically, the return conveyor 38 can be configured as an inclined belt conveyor, that is, the higher end of the return conveyor 38 is connected to the inside of the feed hopper 37. In addition, several partitions are evenly distributed along the length of the belt on the return conveyor 38. A guide plate 362 can be installed at the discharge end of the recycling channel so that the waterproof plugs passing through the discharge end of the recycling channel can flow into the return conveyor 38. This makes it easy to add the waterproof plugs on the recycling channel back into the feed hopper 37 for repackaging.

[0035] Furthermore, such as Figure 2 , Figure 8 and Figure 9 As shown, a second baffle plate 361 is installed on the side of the recycling belt conveyor 36 away from the first feeding belt conveyor 31. The second baffle plate 361 is parallel to the length direction of the recycling belt conveyor 36. Specifically, during use, the second baffle plate 361 can prevent the waterproof plug on the recycling channel from falling off during the conveying process.

[0036] The specific setup of the visual counting mechanism 39 is as follows: Figure 10 and Figure 11 As shown, the visual counting mechanism 39 includes an adjustment bracket mounted on the support platform 6. A counting camera 395 capable of adjusting the shooting angle is mounted on the adjustment bracket. The counting camera 395 can be set as an industrial camera of the existing technology, and is electrically connected to the controller 1. The counting camera 395 is positioned opposite to the discharge end of the two sets of feed belt conveyors, that is, the shooting direction of the counting camera 395 is towards the discharge end of the two sets of feed belt conveyors. In addition, a light source can also be set inside the housing 5 to ensure the brightness of the shooting environment in which the counting camera 395 is located.

[0037] The specific configuration of the adjusting bracket is as follows: The adjusting bracket includes a support 391 vertically mounted on the bearing platform 6. An arc-shaped through hole 392 is horizontally penetrating the support 391. A horizontally distributed pin 393 is mounted on the support 391 at the center of the arc-shaped through hole 392, and an adjusting plate 394 is rotatably connected to the pin 393. An adjusting bolt is provided between the side of the adjusting plate 394 away from the pin 393 and the support 391. The adjusting bolt passes through the arc-shaped through hole 392. The adjusting plate 394 is threadedly connected to the 1st adjustment bolt, and the counting camera 395 is mounted on the adjusting plate 394. Specifically, during use, when the head of the adjusting bolt is pressed against the support 391, the position of the adjusting plate 394 can be fixed on the support 391 to indirectly fix the position of the counting camera 395. After loosening the adjusting bolt, the adjusting plate 394 can be rotated around the pin 393 to adjust the shooting angle of the counting camera 395 to a suitable position. Then, the position of the counting camera 395 can be re-fixed using the adjusting bolt.

[0038] The specific configuration of the bagging device 2 is as follows: Figure 2 , Figures 12 to 19 As shown, the bagging device 2 includes a horizontally arranged frame 21. One end of the frame 21 is detachably and rotatably connected to a bag-carrying shaft 22 parallel to the width direction of the frame 21. Specifically, two supporting rollers 222 are rotatably connected to both ends of the frame 21 at the two ends of the bag-carrying shaft 22. An annular groove 221 is provided at each end of the bag-carrying shaft 22, and both ends of the bag-carrying shaft 22 abut against the two supporting rollers 222 respectively through the annular groove 221. The bag-carrying shaft 22 can be used to carry rolled bags, and the length direction of the bag... Both sides are enclosed; the other end of the frame 21 is located below the receiving device 4 and is equipped with two sets of sealing, cutting and supporting bag mechanisms that are arranged opposite to each other and can move closer or further apart along the length of the frame 21. The frame 21 is also equipped with a guide bag conveying mechanism 23 that can transport the bag between the bag body bearing shaft 22 and the two sets of sealing, cutting and supporting bag mechanisms. Each sealing, cutting and supporting bag mechanism includes a sealing assembly 24, a cutting assembly 25 and a supporting assembly 26. The controller 1 is electrically connected to the sealing assembly 24, the cutting assembly 25 and the supporting assembly 26 and the guide bag conveying mechanism 23 respectively.

[0039] Specifically, during use, the guide bag conveying mechanism 23 guides the rolled-up bag until one end of the bag is positioned between two sets of sealing, cutting, and supporting bag mechanisms. Through the cooperation of the two sets of sealing, cutting, and supporting bag mechanisms, the bag is first formed into a packaging bag using the sealing assembly 24 and the cutting assembly 25. Then, the supporting bag assembly 26 opens the bag opening until a set number of waterproof plugs are inserted into the bag. Finally, the sealing assembly 24 closes the bag opening. This not only automatically processes the packaging bag but also automatically opens and seals it, thus improving the packaging efficiency of waterproof plugs compared to manual operation. After the sealed bag falls under gravity, the guide bag conveying mechanism 23 can continue to transport the bag forward for the next bagging operation.

[0040] The specific setup method for the sealing assembly 24 is as follows: Figure 15 and Figure 16 As shown, each bag sealing assembly 24 includes a transverse plate 241 parallel to the bag body bearing shaft 22 and mounted on the frame 21. A first heat-sealing knife 242, parallel to the transverse plate 241, is mounted on opposite sides of each transverse plate 241. A crossbar 243, parallel to the first heat-sealing knife 242 and mounted on the frame 21, is mounted above each transverse plate 241. Several second heat-sealing knives, equidistantly distributed and spaced apart along the length of the crossbar 243, are mounted on the bottom surface of the crossbar 243. The blade 244 and the controller 1 are respectively connected to the second heat-sealing blade 244 and the first heat-sealing blade 242. Specifically, the second heat-sealing blade 244 and the first heat-sealing blade 242 can share a set of heating sources, but the second heat-sealing blade 244 and the first heat-sealing blade 242 can operate independently to heat and seal the bag. In addition, although two adjacent second heat-sealing blades 244 are spaced apart, multiple second heat-sealing blades 244 can perform multi-point heat sealing on the bag body, and can also completely seal the bag body during use.

[0041] The specific setup of the bag support assembly 26 is as follows: Figures 15 to 19 As shown, each of the bag support assemblies 26 includes a support shaft 261 that is parallel to the transverse plate 241 and can reciprocate relative to the transverse plate 241 along the length of the frame 21. The support shaft 261 is located between the first heat sealing blade 242 and the second heat sealing blade 244. Specifically, each support shaft 261 has two fifth electric telescopic rods 262 that are mounted on the frame 21 and can be extended and retracted synchronously at both ends. The fifth electric telescopic rods 262 are parallel to the length of the frame 21 and are electrically connected to the controller 1. In use, the extension and retraction of the fifth electric telescopic rods 262 can drive the support shaft 261 to reciprocate relative to the transverse plate 241 along the length of the frame 21.

[0042] In addition, several rubber wheel shafts 263 are also installed on opposite sides of the two supporting shafts 261, which are equidistantly distributed along the length direction of the supporting shafts 261 and parallel to the supporting shafts 261. Between each two adjacent rubber wheel shafts 263, a support seat 264 is fixedly installed on the transverse plate 241. The support seat 264 is spaced apart from the supporting shaft 261 to avoid affecting the movement of the supporting shaft 261 along the length direction of the frame 21. Above each support seat 264, there is a horizontally distributed movable plate 265 that can be raised and lowered. The movable plate 265 is located between two adjacent second heat sealing knives 244. The opposite ends of the movable plate 265 are fixedly connected to vertically distributed pressure plates 266. Specifically, the end of the movable plate 265 away from the pressure plate 266 is connected to a sixth electric telescopic rod 267 that is vertically installed on the transverse plate 241 and electrically connected to the controller 1. In use, the movable plate 265 can be raised and lowered by extending and retracting the sixth electric telescopic rod 267.

[0043] The specific setup of the bag cutting component 25 is as follows: Figures 15 to 16 As shown, each bag-cutting assembly 25 includes a cutting blade 251 arranged parallel to the transverse plate 241 and capable of reciprocating relative to the transverse plate 241 along the length direction of the frame 21. The cutting blade 251 is located between the second heat-sealing blade 244 and the support shaft 261, and the cutting blade 251 passes through the gap between the movable plate 265 and the support seat 264 in sequence. Specifically, the two ends of the cutting blade 251 are connected to two seventh electric telescopic rods 252 mounted on the frame 21 and capable of synchronous extension and retraction. The seventh electric telescopic rods 252 are parallel to the length direction of the frame 21 and electrically connected to the controller 1. In use, the extension and retraction of the seventh electric telescopic rods 252 can drive the cutting blade 251 to move relative to the transverse plate 241 along the length direction of the frame 21.

[0044] Specifically, in the initial state, the movable plate 265 is in the raised state to prevent the bag pressing plate 266 from affecting the movement of the cutting blade 251. When replacing a new roll of bag, if one end of the bag is between the two sets of sealing and cutting support mechanisms, the two sets of sealing and cutting support mechanisms can be brought closer together. Then, the second heat-sealing blade 244 can be used alone to seal the bag until the bottom of the packaged bag is formed. After that, the two sets of sealing and cutting support mechanisms are moved away from each other. Then, the bagging operation begins: First, the guide bag conveying mechanism 23 continues to drive the bag forward until the bag is in place, then the two sets of sealing and cutting support mechanisms are brought closer together. Second, the two support shafts 261 are brought closer together so that the rubber wheel shafts 263 are respectively bonded to both sides of the packaged bag. Then, the two cutting blades 251 are brought closer together to cut the bag body to form the bag opening. Then, the two cutting blades 251 are moved away from each other. Simultaneously, the second heat-sealing blade 244 can be used alone to seal the bag until the bottom of the packaged bag is formed. The second heat-sealing blade 244 seals the bottom of the next packaging bag; the third step: move the two support shafts 261 away from each other, and under the action of the rubber wheel shaft 263, make the two sides of the bag opening abut against the support seat 264 respectively. Then, after the two sets of sealing and cutting bag-supporting mechanisms move away from each other, the bag opening of the packaging bag can be fully opened. At this time, the movable plate 265 is lowered so that the bag-pressing plate 266 presses the bag opening to prevent the packaging bag from slipping during the filling process. Then, the waterproof plug can be poured into the packaging bag through the receiving device 4; the fourth step: after the waterproof plug is filled, move the two sets of sealing and cutting bag-supporting mechanisms closer to each other, and use the first heat-sealing blade 242 to seal the bag opening of the packaging bag alone. Then, while the two sets of sealing and cutting bag-supporting mechanisms move away from each other, make the bag-pressing plate 266 loosen the packaging bag. At this time, the sealed packaging bag falls under the action of gravity. By repeating the above steps one to four, the bag filling operation can be repeated.

[0045] Furthermore, such as Figure 13 and Figure 15As shown, one set of sealing and cutting bag-supporting mechanisms is fixedly installed on the frame 21, and the other set of sealing and cutting bag-supporting mechanisms is slidably connected to the frame 21 along the length direction of the frame 21 via guide rail mechanisms 20. Specifically, guide rail mechanisms 20 are installed on both sides of the frame 21 along its length direction. The guide rail mechanism 20 includes slide rails 201 parallel to the length direction of the frame 21, and a slider 202 is slidably connected to each slide rail 201. The slider 202 is connected to the sealing and cutting bag-supporting mechanism. Furthermore, a telescopic component 28 that can drive the sealing and cutting bag-supporting mechanism to reciprocate is connected to this set of sealing and cutting bag-supporting mechanisms. Specifically, the telescopic component 28 includes two fourth electric telescopic rods 282 that can be synchronously extended and retracted. The movable telescopic rods 282 are symmetrically installed on both sides of the frame 21 along its length, and each fourth electric telescopic rod 282 is parallel to the length of the frame 21. The telescopic end of each fourth electric telescopic rod 282 is connected to the sealing and cutting bag support mechanism. The controller 1 is electrically connected to two fourth electric telescopic rods 282 respectively. Specifically, when the telescopic end of the fourth electric telescopic rod 282 is in the extended state, the two sets of sealing and cutting bag support mechanisms are distributed at intervals. When the telescopic end of the fourth electric telescopic rod 282 is retracted, it can drive the sealing and cutting bag support mechanism slidably connected to the frame 21 to move closer to the other set of sealing and cutting bag support mechanisms, so as to realize that the two sets of sealing and cutting bag support mechanisms move closer or further away from each other along the length of the frame 21.

[0046] Furthermore, such as Figure 13 and Figure 15 As shown, a limiting mechanism 29 is installed on the frame 21 to restrict the extension length of the fourth electric telescopic rod 282. Specifically, the telescopic ends of the fourth electric telescopic rod 282 are connected to the sealing and cutting bag support mechanism through connecting plates 281. Each limiting mechanism 29 includes a threaded rod 292 installed on the frame 21 and arranged parallel to the fourth electric telescopic rod 282. The connecting plates 281 are slidably sleeved on the threaded rods 292, and each threaded rod 292 is threadedly connected with a limiting block 291 that can restrict the extension length of the fourth electric telescopic rod 282. Specifically, during use, when the telescopic end of the fourth electric telescopic rod 282 is extending, the limiting block 291 can block the connecting plates 281 to limit the extension length of the fourth electric telescopic rod 282. In addition, by rotating the limiting block 291 on the threaded rod 292, the position of the limiting block 291 can be adjusted along the length direction of the threaded rod 292. This also allows adjustment of the maximum extension length of the fourth electric telescopic rod 282, so as to adjust the spacing between the two sets of sealing and cutting bag support mechanisms when they are distributed at intervals.

[0047] The specific configuration of the guiding bag conveying mechanism 23 is as follows: Figure 13 and Figure 14As shown, the guiding bag conveying mechanism 23 includes several guide shafts 231 distributed along the length of the frame 21 and capable of rotation. Each guide shaft 231 is parallel to the bag-bearing shaft 22. One guide shaft 231 is a drive shaft 232, and a drive component electrically connected to the controller 1 is driven on the drive shaft 232. The drive component can be a drive motor. A bag-clamping shaft 233 is provided on the side of the drive shaft 232 away from the bag-bearing shaft 22, parallel to the drive shaft 232. Both ends of the bag-clamping shaft 233 are rotatably connected to the frame 21. Specifically, the bag-clamping shaft 23... 3 can rotate synchronously with the drive shaft 232, and the rotation directions are opposite. In use, after the bag body passes around the guide shaft 231 in sequence, the bag body passes around the drive shaft 232 from the top and is positioned between the drive shaft 232 and the clamping shaft 233. At this time, the drive shaft 232 and the clamping shaft 233 cooperate to apply a certain clamping force to the bag body. Then, when the drive shaft 232 is driven to rotate by the drive component, since the rotation directions of the drive shaft 232 and the clamping shaft 233 are opposite, the rolled bag body can be unwound and the bag body can be conveyed forward.

[0048] Furthermore, such as Figures 12 to 14 As shown, a ranging mechanism 27 is mounted on the frame 21 located on the side of the drive shaft 232 away from the bag clamping shaft 233. The ranging mechanism 27 includes a U-shaped through-beam sensor 271 mounted on the frame 21 and a ranging shaft 272. The ranging shaft 272 is parallel to the drive shaft 232, and one end of the ranging shaft 272 is rotatably connected to the frame 21 and driven by the drive shaft 232 via a belt drive mechanism or a chain drive mechanism. A ranging disk 273 is coaxially mounted on the other end of the ranging shaft 272. The edge of the ranging disk 273 is located inside the U-shaped through-beam sensor 271, and the ranging disk 273... Multiple through holes 274 are provided at equal intervals along the circumference of the measuring disk 273 at the edge position. The controller 1 is electrically connected to the U-shaped through-beam sensor 271. Specifically, in use, the measuring shaft 272 can rotate synchronously under the drive of the drive shaft 232 to drive the measuring disk 273 to rotate. During the rotation of the measuring disk 273, the multiple through holes 274 on the measuring disk 273 can pass through the U-shaped through-beam sensor 271 in sequence. This allows the rotation angle of the drive shaft 232 to be measured, so as to measure the distance the bag body moves forward in real time, thereby making it easier to ensure that each packaging bag has the same size specifications.
