Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging material production equipment technology, and in particular to an integrated device for bubble wrap inflation and separation. Background Technology
[0002] Currently, the bubble wrap separator and the bubble wrap inflator are two separate machines. During operation, due to potential debugging factors, the production speeds of the two machines are highly likely to be asynchronous. Forcing them to operate together could cause the consumable material to break due to this speed discrepancy. Therefore, an additional mesh frame is needed to buffer the material during operation. Furthermore, to achieve continuous automatic operation, a material level sensor is required to detect whether the material level in the frame is too low or too high, thus controlling the operation and shutdown of the bubble wrap machine.
[0003] In this existing working method, the addition of the wire mesh frame system increases the overall size. Furthermore, since the wire mesh frame serves as a buffer for material storage, it typically requires a large floor area, making the entire system unsuitable for confined spaces. Additionally, the system's weight necessitates placing the bubble wrap inflator and separator at a high position above the wire mesh frame, resulting in a high center of gravity, insufficient stability, and potential safety hazards.
[0004] In addition, the additional wire mesh system and detection sensors will increase the production and assembly costs of the entire system, resulting in insufficient overall competitiveness of the equipment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides an integrated bubble wrap inflation and separation device. It integrates bubble wrap inflation and separation functions, eliminating the need for an additional mesh frame system for material storage, effectively reducing the production and assembly costs of the entire system. Furthermore, it avoids the safety hazards associated with placing the bubble wrap inflation machine and bubble wrap separation equipment at elevated positions in existing methods.
[0006] According to a first aspect of the present invention, a bubble film inflation and separation integrated device is provided, comprising:
[0007] A feeding module includes a feeding rod for holding consumable rolls;
[0008] An inflation module, including a blower module, is used to inflate the opening of a consumable to form a bubble film.
[0009] The heating module is used to heat seal the opening of the bubble wrap and to transport the bubble wrap downstream.
[0010] The separation module includes a conveyor belt assembly for conveying the bubble film toward the outside of the device's outlet;
[0011] The feeding module, inflation module, heating module, and separation module are arranged sequentially on the main body of the equipment.
[0012] This utility model's integrated bubble wrap inflation and separation device uses a feeding assembly to feed the material, followed by inflation using an inflation module to form bubble wrap. A heating module then heat-seals the openings of the bubble wrap, creating a complete and continuous bubble wrap product. When the separation process is initiated, such as by manually pressing a control button, the heating module stops to hold the bubble wrap, while the separation module continues operating, working in conjunction with the heating module to tear the bubble wrap. The torn, separated bubble wrap is then conveyed to the outlet. Because the separation module is integrated into the overall device, its conveying speed matches the overall feeding and bubble wrap production speed, eliminating the need for an additional wire mesh system for material storage. This utility model's integrated bubble wrap inflation and separation device combines bubble wrap inflation and separation functions. It cleverly employs the linkage between the heating module and the separation module used for conveying the bubble wrap, integrating the bubble wrap inflation and separation functions into the overall equipment. This effectively reduces the production and assembly costs of the entire system, while also avoiding the safety hazards caused by placing the bubble wrap inflation machine and bubble wrap separation equipment at a high position in existing working methods.
[0013] In some possible implementations, it also includes:
[0014] The detection module is used to determine the position where the bubble wrap needs to be torn and to control the operation of the entire device. The detection module is located between the heating module and the separation module.
[0015] Therefore, with this setup, the detection module can detect the end break of the bubble wrap and determine the position where the bubble wrap product needs to be torn. This allows it to work in conjunction with other modules of the equipment to automatically determine the position where the bubble wrap needs to be torn during operation and automatically start the separation process to tear the bubble wrap.
[0016] In some possible implementations, a clamping module is also included, comprising a clamping member and a clamping drive member, the clamping drive member being used to drive the clamping member to move in order to clamp the bubble film, the clamping module being disposed upstream of the separation module.
[0017] Therefore, with this configuration, in addition to the heating module clamping the bubble wrap, the clamping drive of the clamping module can also be controlled to move the clamping components to hold the bubble wrap. Furthermore, because of the additional clamping module, in other possible implementations, the bubble wrap can be clamped solely by the clamping module, thus avoiding continuous heating of the bubble wrap by the heating module, which could damage the bubble wrap and affect the quality of the produced bubble wrap.
[0018] In some possible implementations, the clamping member includes a pressure roller, and the lower part of the device body is provided with a platform for clamping bubble film that cooperates with the pressure roller. The platform is located on the feed port side of the separation module. The pressure roller is connected to a clamping link. One end of the clamping link is rotatably mounted on the device body via a rotating shaft, and the other side of the rotating shaft is connected to a clamping drive member.
[0019] Therefore, this configuration allows the bubble wrap to be clamped using a platform located at the bottom of the equipment body and pressure rollers forming the clamping components. The additional platform at the bottom of the equipment body not only serves to clamp the bubble wrap in conjunction with the clamping components but also acts as an auxiliary support structure before the bubble wrap enters the separation module. This ensures that the bubble wrap is more evenly distributed when entering the separation module, improving the product quality of the separated bubble wrap.
[0020] In some possible implementations, the heating module includes a heating wheel and a heat-sealing auxiliary wheel. The heat-sealing auxiliary wheel is configured to rotate actively. The wheel surface of the heating wheel abuts against the wheel surface of the heat-sealing auxiliary wheel to heat-seal the opening of the bubble film and drive the bubble film to be conveyed downstream.
[0021] Therefore, this design allows for the heat sealing of the openings in the inflated bubble wrap using heating wheels and heat-sealing auxiliary wheels. Simultaneously, the overall heating module also serves as the primary transmission structure for conveying consumables during equipment operation, driving the feeding of consumables. Since heat sealing is the final step in the initial inflation section of the overall equipment, this design allows for better control of the bubble wrap production speed. Furthermore, compared to existing bubble wrap inflators, which primarily use Teflon tape for indirect heat transfer during heat sealing (a method that limits production speed and leads to premature wear and breakage of the tape, affecting normal operation), this invention uses heating wheels instead of heating tapes for heat sealing. These wheels offer higher thermal conductivity, allowing for high-speed operation and increasing the overall production speed of the equipment.
[0022] In some possible implementations, the heating wheel is provided with a lifting drive, which is used to drive the heating wheel to move so that the wheel surface of the heating wheel separates from the wheel surface of the heat sealing auxiliary wheel.
[0023] Therefore, by setting it up in this way, the heating wheel can be raised during the separation process to avoid stopping the feeding and pausing the operation of the bubble wrap inflation function, thus preventing the heating wheel from continuously heating the bubble wrap and affecting the quality of the produced bubble wrap.
[0024] In some possible implementations, a sealing module is further provided between the inflation module and the heating module, the sealing module being used to clamp the opening of the sealing bubble film.
[0025] Therefore, by using this configuration, the sealing module can clamp and seal the opening of the inflated bubble film, and then transport it to the heating module for heat sealing. This effectively alleviates the air leakage that easily occurs before the inflated bubble film is transported to the heating module, thereby improving the quality of the produced bubble film.
[0026] In some possible implementations, the sealing module includes a row of first gear sets disposed on a first side of the bubble film and a row of second gear sets disposed on a second side of the bubble film. The first gear set includes at least one first gear disposed on the first side of the bubble film, and the second gear set includes at least one second gear disposed on the second side of the bubble film. The difference in the number of the first gear and the second gear is no more than 1. The first gears of the first gear set and the second gears of the second gear set are arranged at intervals, and adjacent first gears and second gears mesh with each other. The sealing module also includes a sealing drive for driving at least one first gear or at least one second gear to rotate.
[0027] Therefore, this configuration allows for the clamping and sealing of the bubble film opening through the meshing transmission between the first and second gear sets. Since both the first and second gear sets can contain multiple gears, each meshing with an adjacent set, this effectively ensures sealing stability during transport within the entire sealing module. Furthermore, this meshing arrangement means that only one sealing drive is needed to operate the multiple gears in the overall sealing module; the rotation of other gears is achieved through meshing transmission. This reduces the cost of installing drive components while effectively ensuring sealing performance during transmission.
[0028] In some possible implementations, the heating module includes a heating wheel and a heat-sealing auxiliary wheel, the heat-sealing auxiliary wheel is configured to rotate actively, and the heating wheel is provided with a lifting drive member, which is used to drive the heating wheel to move.
[0029] The heating wheel is provided with gear teeth. The heating wheel meshes with the first gear set or the second gear set through the drive gear. When the heating wheel is driven to move by the lifting drive, the movement path is set as an arc-shaped movement path with the rotation center of the drive gear as the reference. The sealing drive is set to drive the heating wheel to rotate by the heat sealing auxiliary wheel. The heating wheel then meshes with the drive gear to drive at least one first gear or at least one second gear to rotate.
[0030] Therefore, this design eliminates the need for a separate drive module for the sealing module, effectively reducing equipment costs and overall weight. It also saves space by eliminating the need for the drive module, thus reducing the overall size of the equipment. Simultaneously, when the heating wheel is lifted, the sealing module stops operating, providing a clamping effect on the bubble wrap and further securing it. Furthermore, the movement path of the heating wheel when lifted is designed as an arc formed around the rotation center of the drive gear. This prevents collisions between the teeth of the heating wheel and the drive gear during the resetting process, ensuring that the heating wheel remains engaged with the drive gear while lifted, thus avoiding potential safety hazards.
[0031] In some possible implementations, a consumable quantity detection module is further provided upstream of the inflation module. The consumable quantity detection module includes a paddle structure, one end of which is hinged to the main body of the device. The hinge rotation axis of the paddle structure is perpendicular to the consumable passing through the paddle structure. The paddle structure has a first position and a second position. The consumable quantity detection module also includes a counting unit. When the paddle structure is in the first position, it is paddled by the opening of the consumable being conveyed downstream to rotate through the second position. When the paddle structure passes through the second position, the counting unit is triggered. The consumable quantity detection module also includes a paddle reset drive for driving the paddle structure back to the first position.
[0032] Therefore, with this setup, when the consumables pass through the consumables quantity detection module, it will drive the paddle structure to rotate, thereby causing the paddle structure to rotate past the second position and triggering the counting unit to count. In this way, the consumables quantity detection module can count the number of consumables used, and combined with the machine's production speed, the actual operating position of the consumables can be clearly understood.
[0033] In some possible implementations, the upstream side of the paddle structure is further provided with an opening structure, the opening structure including an opening rod and a blade disposed on one side of the opening rod.
[0034] Therefore, this setup allows for the cutting of consumables with closed membrane structures using an open structure, creating open membranes that are then transported to the downstream inflation module for inflation to form bubble membranes. The open structure is positioned upstream of the consumable quantity detection module, enabling the quantity of consumables to be counted immediately after the closed membrane is cut via a paddle mechanism. This combines the two processes into one, simplifying the overall equipment structure.
[0035] In some possible implementations, the feeding module further includes a feeding drive for driving the feeding rod to rotate for active feeding.
[0036] Therefore, this design effectively mitigates the impact caused by the excessive weight of the consumable roll during feeding, preventing consumable breakage. In actual production, consumable rolls are typically very large, resulting in significant overall weight and making them difficult to pull and rotate. When the machine operates, pulling the consumable conveyor exerts an impact force on the roll, which can easily cause breakage—a problem typically found in large bubble wrap production equipment. This invention addresses this by adding an active feeding and rotating function to the feeding rod, providing the consumable roll with an active rotational speed, thus effectively preventing breakage during machine operation.
[0037] In some possible implementations, the downstream of the feeding module further includes a film buffer module, which includes a buffer roller. The consumable is conveyed downstream around the buffer roller. The buffer roller is configured to move relative to the main body of the device between a third position and a fourth position. The film buffer module also includes a detection unit, which is configured to control the feeding drive to increase the feeding speed when it detects that the buffer roller has moved to the fourth position. The film buffer module also includes a buffer reset drive for driving the buffer roller back to the third position.
[0038] Therefore, with this setup, the consumable material, after being released from the feeding module, first passes through the film buffer module for storage and buffering. It's understandable that because the consumable roll is very heavy and bulky, under a fixed rotation speed of the feeding drive, the outermost layer of consumable material gradually slows down during use, making it impossible to match the machine's bubble wrap conveying and production speeds, potentially leading to tearing. By adding a buffer roller to the film buffer module, as the outermost layer of the consumable roll slows down after passing over it, it presses against the buffer roller, causing it to move towards the fourth position. When the buffer roller reaches the fourth position, it triggers the detection unit, which then controls the feeding drive to increase the feeding speed, thus preventing the consumable material from tearing. When the feeding speed of the feeding drive increases, the buffer roller will gradually reset to the third position under the drive of the buffer reset drive, realizing material storage buffering, until the speed of the outermost layer of consumable roll is again slower than the machine's bubble wrap conveying speed and bubble wrap production speed, thus triggering the material storage buffering again. This utility model further incorporates a film buffer module for material storage buffering, thereby effectively preventing the consumable from tearing during machine operation and ensuring the normal operation of the equipment.
[0039] In some possible implementations, the downstream of the feeding module also includes a guide roller, around which the consumable is fed downstream in the direction required for feeding into the inflation module.
[0040] Therefore, by setting it up in this way, the direction of consumable delivery can be changed, allowing the consumable to enter the inflation module more effectively, preventing the consumable from shifting and affecting the normal operation of the inflation module. It also eliminates the need for a correction module, reducing the overall cost of the equipment.
[0041] In some possible implementations, the feeding module is located at the upper part of the equipment body, while the inflation module, heating module, and separation module are all located at the lower part of the equipment body.
[0042] Therefore, this design allows for a more rational arrangement of the various parts of the overall equipment, avoiding instability of the center of gravity. It also utilizes vertical space to reduce the overall length of the equipment and minimize its footprint. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0053] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0054] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising" or "including" include not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0055] The present invention will now be described in further detail with reference to the accompanying drawings.
[0056] Figure 1 and Figure 2 The schematic diagram illustrates the overall structure of the integrated bubble film inflation and separation device according to one embodiment of the present invention. (Refer to...) Figure 1 and Figure 2 As shown, the bubble wrap inflation and separation integrated device of this utility model includes a feeding module 1, an inflation module 2, a heating module 5, and a separation module 7. The feeding module 1, inflation module 2, heating module 5, and separation module 7 are arranged sequentially on the main body 9 of the equipment according to the order of process execution. Specifically, to make the overall layout of the equipment more reasonable and reduce the occupied area, the feeding module 1 can be set at the upper part of the main body 9, while the inflation module 2, heating module 5, and separation module 7 are all set at the lower part of the main body 9. Since the consumable rolls are usually very large in volume and weight, placing the feeding module 1 at the upper part can save more space in the overall equipment. At the same time, placing more modules at the lower part of the main body 9 can also effectively improve the stability of the overall equipment during installation.
[0057] The feeding module 1 is located on the upper part of the main body 9 of the equipment, as shown in the reference. Figure 3 and Figure 4As shown, the feeding module 1 includes a feeding rod 11 extending outward from the main body 9 of the equipment. One end of the feeding rod 11 is rotatably mounted on the main body 9 of the equipment. The consumable roll is wound up so that its center is placed on the feeding rod 11, so that it can rotate with the rotation of the feeding rod 11 to realize the feeding of consumables.
[0058] The inflatable module 2 is located at the lower part of the main body 9 of the equipment, as shown in the reference. Figure 4 and Figure 8 As shown, the inflation module 2 is positioned below the material feeding module 1. The inflation module 2 includes an air nozzle 21 and a blower module 22 connected to the air nozzle 21. The structures of the air nozzle 21 and the blower module 22 can be designed with reference to existing structures and modules in bubble wrap inflation machines; this invention does not limit these aspects. Specifically, refer to... Figure 5 As shown, the air nozzle 21 is set in an "L" shape with its end facing downstream. When the consumable is conveyed, its opening passes through the air nozzle 21, which in turn causes the consumable to be blown into the air to form a bubble film, and then continues to be conveyed downstream to enter the heating module.
[0059] In some possible implementations, a sealing module 3 may be provided between the inflation module 2 and the heating module 5 to clamp and seal the opening of the inflated bubble membrane, preventing gas leakage from the bubble membrane during its transition from leaving the inflation module 2 to entering the heating module 5. Specifically, the sealing module 3 may include a row of first gear sets 31 disposed on the first side of the bubble membrane and a row of second gear sets 32 disposed on the second side of the bubble membrane, to achieve conveying and clamping sealing of the bubble membrane through gear meshing and transmission. The first gear set 31 may include at least one first gear disposed on the first side of the bubble membrane, and the second gear set 32 may include at least one second gear disposed on the second side of the bubble membrane. The difference in the number of first gears and second gears is no more than one, and the first gears and second gears are arranged at intervals and mesh with each other. (Refer to...) Figure 4 and Figure 5 As shown, exemplarily, in Figure 3 and Figure 4 In the illustrated embodiment, the first gear is a gear disposed on the upper side of the bubble film, and the second gear is a gear disposed on the lower side of the bubble film. There are four first gears and four second gears, arranged at intervals, with adjacent first and second gears meshing with each other. The sealing module 3 also includes a sealing drive for driving at least one first gear or at least one second gear to rotate. Specifically, in some possible embodiments, the sealing drive can be configured to be directly connected to the first gear or the second gear to drive the operation of the first gear set 31 and the second gear set 32.
[0060] In addition, in some other possible embodiments, a consumable quantity detection module 4 may be provided upstream of the inflation module 2. The consumable quantity detection module 4 can count the number of consumables used and, combined with the machine's production speed, clearly indicate the actual operating position of the consumables. Specifically, the consumable quantity detection module 4 may include a lever structure 41, one end of which is hinged to the device body 9, and the hinge rotation axis 414 of the lever structure 41 is perpendicular to the consumables passing through the lever structure 41. The consumable quantity detection module 4 also includes a counting unit 415. The lever structure 41 has a first position 42 and a second position 43. When the lever structure 41 is in the first position 42, it is moved towards the opening of the downstream consumables to rotate through the second position 43, and when the lever structure 41 passes through the second position 43, the counting unit 415 is triggered. The consumable quantity detection module 4 also includes a lever reset drive for driving the lever structure 41 back to the first position 42. Specifically, the counting unit 415 can be located at the first position 42, so that counting is triggered when the paddle structure 41 is reset to the first position 42. Alternatively, the counting unit 415 can be located at the second position 43, so that counting is triggered when the paddle structure 41 is moved past the second position 43. For example, refer to... Figure 7 As shown, in Figure 7 In the illustrated embodiment, the paddle structure 41 includes a sheet-like paddle body 411 and a clamping block 412 connected to one side of the paddle body 411. The clamping block 412 is hinged to a connecting member 413 extending outward from the side of the device body 9 via a hinged rotation shaft 414, allowing the paddle body 411 to be held parallel to the horizontal plane and actuated by the opening of the conveyed consumables. The counting unit 415 can be a commonly used unit module such as a photoelectric sensor. A protrusion extends from one side of the clamping block 412, and the counting unit 415 is located at the position of the protrusion when the paddle structure 41 is in the first position 42. The reset drive can be a torsion spring mounted on the hinged rotation shaft 414, so that the paddle structure 41 can be reset to the first position 42 under the torsion of the torsion spring after being actuated. Alternatively, the reset drive can be a tension spring, so that the paddle structure 41 can be pulled back to the first position 42 under the tension of the tension spring after being actuated. The reset drive can also be other structures or modules that can drive the structure to rotate. This invention will not elaborate on this structure in detail and will not limit it.
[0061] Furthermore, in some possible implementations, the consumable may be a closed membrane structure, requiring the blade 442 to cut open the closed portion to form an open membrane before it can be conveyed to the inflation module 2 for inflation. Additionally, in the consumable quantity detection module 4, an open structure 44 may be provided upstream of the connector 413. (Refer to...) Figure 7 As shown, in Figure 7 In the embodiment shown, the opening structure 44 includes an opening rod 441 and a blade 442 disposed on the side of the opening rod 441 facing the device body 9. When the consumable is conveyed through the opening structure 44, it is first opened by the opening rod 441. Then, as the consumable is conveyed, the closed part of the consumable is cut by the blade 442 to form an opening membrane. Then, it is counted by the paddle structure 41 and finally conveyed to the inflation module 2 for inflation.
[0062] The heating module 5 is located at the lower part of the main body 9 of the equipment, as shown in the reference. Figure 3 As shown, the heating module 5 is located on the right side of the inflation module 2 and downstream of it. The heating module 5 includes a heating wheel 51 and a heat-sealing auxiliary wheel 52. The heat-sealing auxiliary wheel 52 is configured to rotate actively, and the surface of the heating wheel 51 abuts against the surface of the heat-sealing auxiliary wheel 52 to heat-seal the opening of the bubble film being held and conveyed between the surfaces of the heating wheel 51 and the heat-sealing auxiliary wheel 52, and to drive the bubble film downstream. The surface of the heating wheel 51 is provided with metal wires for heat-sealing the bubble film. The specific structure of the heating wheel 51 and the heat-sealing auxiliary wheel 52 can be referenced from the relevant structures and modules in existing bubble film inflators; this invention does not limit this. Specifically, the heat-sealing auxiliary wheel 52 is connected to a heating module drive component 54 for driving the heat-sealing auxiliary wheel 52 to rotate actively, thus serving as the main transmission structure for consumable material conveying during the operation of the overall equipment. (Refer to...) Figure 8 As shown, in Figure 8 In the illustrated embodiment, the heating module drive 54 is disposed within the main body 9 of the equipment to drive the rotation of the heat-sealing auxiliary wheel 52. The heating module drive 54 may include a drive motor and two pulleys, which rotate synchronously with the shaft of the drive motor and synchronously with the heat-sealing auxiliary wheel 52, respectively. The two pulleys are driven by a belt drive to achieve the driving of the heat-sealing auxiliary wheel 52. Other drive control methods may also be used for the heating module drive 54, which are not limited in this invention. The consumable material is continuously conveyed downstream under the drive of the heating module 5, inflated by the inflation module 2, and then heat-sealed by the heating module 5.
[0063] The separation module 7 is located at the lower part of the main body 9 of the equipment, as shown in the reference. Figure 3As shown, the separation module 7 is located to the right of the detection module 61 and downstream of it. The separation module 7 includes a conveyor belt assembly 71 with two conveyor belts arranged vertically and horizontally, spaced apart to allow the bubble wrap to pass between them. The separation module 7 has an inlet 72 and an outlet 73. The inlet 72 is located on the right side of the detection module 61, and the outlet 73 is on the other side. During operation, the separation module 7 continuously conveys the bubble wrap from the inlet 72 to the outlet 73 at a speed comparable to the conveying speed of the bubble wrap. When the separation process is initiated, the heating module 5 stops operating to clamp the bubble wrap, and the separation module 7 continues to operate, cooperating with the heating module 5 to tear the bubble wrap and convey the torn bubble wrap to the outlet 73.
[0064] In some possible implementations, a detection module 61 may also be provided between the heating module 5 and the separation module 7. The detection module 61 is located at the lower part of the device body 9, as shown in the reference diagram. Figure 1 As shown, the detection module 61 is located to the right of the heating module 5 and downstream of it. The detection module 61 can be a commonly used unit module such as a photoelectric sensor. Specifically, as one possible implementation, the detection module 61 can detect the position of the previously torn end of the passing bubble film. When the equipment receives the required length of bubble film to be separated, it determines the time required based on the current bubble film conveying speed, and then controls the operation of the heating module 5 and the separation module 7. After the separation process is completed, the length of the torn bubble film is the required length. Furthermore, after the detection module 61 detects the break at the end of the bubble film and a corresponding amount of time has elapsed, it can determine the position of the bubble film to be torn, and then controls the operation of the entire equipment to start the separation process, stopping the operation of the heating module 5 to hold the bubble film, and cooperating with the separation module 7 to achieve automatic tearing and separation of the bubble film. Alternatively, as another possible implementation, when the overall device is also equipped with a consumable quantity detection module 4, the length of the bubble wrap torn after the separation process at the current moment can be determined by combining the detection module 61 and the consumable quantity detection module 4. Specifically, since the consumable can be triggered when it passes through the consumable quantity detection module 4 to count the number of consumables used, after the detection module 61 detects the break at the end of the bubble wrap, based on the number of uses detected by the consumable quantity detection module 4, when the number detected by the consumable quantity detection module 4 reaches a certain value, the length of the bubble wrap torn after the separation process at the current moment can be determined, the position of the bubble wrap to be torn can be determined, and the heating module 5 can be controlled to stop to clamp the bubble wrap, thus cooperating with the separation module 7 to achieve automatic tearing and separation of the bubble wrap.
[0065] In some possible implementations, a clamping module 62 may also be provided between the separating module 7 and the heating module 5. (See reference...) Figure 3 and Figure 4 As shown, specifically, the clamping module 62 is located at the lower part of the equipment body 9. It can be positioned on the side of the discharge port 72 of the separation module 7 and above the detection module 61. The clamping module 62 includes a clamping member 63 and a clamping drive member 64. The clamping drive member 64 is used to drive the clamping member 63 to move, thereby controlling the clamping member 63 to clamp the bubble film and preventing the bubble film from moving back and forth. Specifically, the clamping member 63 can be configured as a clamp structure so that the clamping member 63 can clamp the bubble film independently. The clamping member 63 can also be configured as a structure that clamps the bubble film by cooperating with other structures on the equipment body 9, such as a pressure rod, pressure roller, etc. For example, see reference. Figure 3 and Figure 4 As shown, in Figure 3 and Figure 4 In the illustrated embodiment, the clamping member 63 is configured as a pressure roller, and a platform 91 for clamping bubble film, which cooperates with the pressure roller, is provided on the lower part of the device body 9 extending outward from the side of the device body 9. The platform 91 is located on the inlet 72 side of the separation module 7. One end of the clamping member 63 is connected to a clamping connecting rod 631, and one end of the clamping connecting rod 631 is rotatably mounted on the device body 9 via a rotating shaft. The other side of the rotating shaft is connected to a clamping drive member 64 to control the rotation of the rotating shaft, thereby controlling the clamping member 63 to swing with the clamping connecting rod 631 and abut against the platform 91 to clamp the bubble film. The clamping drive member 64 can be configured as a crank structure driven by a linear motor, thereby driving the rotating shaft to rotate. Once the detection module 61 determines the position where the bubble wrap needs to be torn, the clamping module 62, driven by the clamping drive 64, swings towards the platform 91. This allows it to cooperate with the platform 91 to clamp the bubble wrap, preventing it from moving back and forth, thus facilitating the separation module 7 to tear the bubble wrap and complete the bubble wrap separation process. In this embodiment, the addition of the clamping module 62, in conjunction with the heating module 5, improves the stability of the bubble wrap clamping.
[0066] Furthermore, since a clamping module 62 is additionally provided to clamp the bubble wrap, in other possible implementations, the bubble wrap can be clamped solely by the clamping module 62, thereby avoiding continuous heating of the bubble wrap by the heating module 5 while it is clamping, which could damage the bubble wrap and affect the quality of the produced bubble wrap. It is understood that when the detection module 61 is activated to execute the separation process, the entire equipment will stop operating to halt the continued conveying of the bubble wrap by the separation module 7, and the clamping module 62 will be controlled to clamp the bubble wrap. Then, the separation module 7 will resume operation independently, working in conjunction with the clamping module 62 to complete the separation of the bubble wrap. In this process, although the entire equipment stops conveying the bubble wrap, the heating module 5 cannot cool down immediately, and even if it could cool down immediately, it would take time to reheat to the operating temperature. Therefore, the heating wheel 51 of the heating module 5 needs to be continuously heated. When the entire device stops conveying bubble wrap, the heating wheel 51 will continue to heat the same position of the bubble wrap, which may damage the bubble wrap. Therefore, in some possible embodiments, the heating wheel 51 of the heating module 5 may be equipped with a lifting drive 53. The lifting drive 53 is used to drive the heating wheel 51 to move, so that the wheel surface of the heating wheel 51 and the wheel surface of the heat sealing auxiliary wheel 52 are separated, avoiding continuous heating of the same position of the bubble wrap. At this time, when the detection module 61 determines the position of the bubble wrap to be torn, it also controls the lifting drive 53 to move, so as to drive the heating wheel 51 to lift. It can be understood that, in this embodiment, since the heating wheel 51 is lifted, it cannot cooperate with the heating auxiliary wheel 52 to convey bubble wrap. Therefore, the heating auxiliary wheel 52 may or may not stop running. For example, refer to Figure 8 As shown, in Figure 8 In the embodiment shown, the shaft of the heating wheel 51 is connected to a lifting drive 53, which can be configured as a linear motor or a crank structure driven by a linear motor, thereby driving the heating wheel 51 to lift.
[0067] Furthermore, in this embodiment, the operation of the sealing module 3 can be configured to be driven by the heating module 5. Specifically, refer to... Figure 3 and Figure 4 As shown, in Figure 3 and Figure 4In the illustrated embodiment, a drive gear 33 is positioned above the first gear of the sealing module 3, meshing with the first gear. Simultaneously, the heating wheel 51 also has teeth that mesh with the drive gear 33. Thus, when the heating wheel 51 rotates, it drives the drive gear 33 to rotate, thereby operating the entire sealing membrane assembly 3. When the heating wheel 51 is lifted, the entire sealing module 3 immediately stops operating to hold the bubble wrap. This design eliminates the need for a separate drive structure to rotate the sealing module 3 itself. However, since the heating wheel 51 needs to move during the bubble wrap separation process, if it disengages from the drive gear 33 after moving, gear collisions can easily occur after the heating wheel 51 resets, potentially creating a safety hazard. Therefore, in this embodiment, the movement path of the heating wheel 51 can be set as an arc-shaped movement path based on the rotation center of the drive gear 33, so that when the heating wheel 51 is lifted, it moves in an arc around the rotation center of the drive gear 33, allowing the heating wheel 51 and the drive gear 33 to maintain a continuous meshing state, avoiding the safety hazard of gear collision. Specifically, refer to... Figure 4 and Figure 8 As shown, in addition to the movement of the rotating shaft of the heating wheel 51, an auxiliary slider 511 connected to the heating wheel 51 can also be provided for the movement of the heating wheel 51. The main body 9 of the device is also provided with a sliding groove 512 that cooperates with the auxiliary slider 511. The sliding groove 512 is also set in an arc shape to assist the movement of the heating wheel 51.
[0068] In actual production, the consumable rolls are usually very large, resulting in a significant overall weight that makes them difficult to pull and rotate. When the machine operates, pulling the consumable conveyor exerts an impact force on the roll, which can easily cause breakage – a problem typically found in large bubble wrap production equipment. Therefore, in some possible implementations, the feeding module 1 may further include a feeding drive 12 for actively feeding the consumable roll by rotating the feeding rod 11. The feeding drive 12 may consist of a drive motor and two pulleys, which rotate synchronously with the drive motor shaft and the feeding rod 11, respectively. A belt drive is used between the two pulleys to drive the feeding rod 11. Other drive control methods can also be used for the feeding drive 12, which are not limited in this invention. The active feeding setting of the feeding rod 11 provides the consumable roll with an active rotational speed, effectively preventing breakage of the consumable roll during machine operation.
[0069] Furthermore, due to the significant weight and volume of the consumable roll, even with a fixed rotation speed of the feeding drive 12, the outermost layer of consumable roll will gradually slow down during use. This makes it impossible to match the machine's bubble wrap conveying and production speeds, potentially leading to tearing of the consumable roll. In some possible implementations, a film buffer module 8 may also be included downstream of the feeding module 1. (Refer to...) Figure 3 and Figure 4 As shown, the film buffer module 8 is located on the upper part of the equipment body 9 and to the left of the feeding module 1. The film buffer module 8 includes a buffer roller 81, around which consumables are fed downstream. One end of the buffer roller 81 is located on the side of the equipment body 9, and the buffer roller 81 is configured to move relative to the equipment body 9 between a third position 82 and a fourth position 83. The film buffer module 8 also includes a detection unit 84, which is configured to trigger the feeding drive 12 to increase the feeding speed when the buffer roller 81 is detected to have moved to the fourth position 83. The film buffer module 8 also includes a buffer reset drive 85 for resetting the buffer roller 81 to the third position 82. Specifically, refer to... Figure 3 and Figure 4 As shown, one end of the buffer roller 81 is connected to a buffer link 811. One end of the buffer link 811 is rotatably mounted on the side of the device body 9 via a rotating shaft, allowing the buffer roller 81 to move relative to the device body 9 around the rotating shaft. The movement path is arc-shaped, with the upper end of the arc being the third position 82 and the lower end being the fourth position 83. A baffle 812 is provided on the buffer link 811. The detection unit 84 is located on the side of the device body 9 at the position where the buffer roller 81 is blocked by the baffle 812 when it is in the third position 82. The detection unit 84 can be a commonly used unit module such as a photoelectric sensor. The buffer reset drive 85 can be a tension spring with one end connected to the device body 9 and the other end connected to the buffer roller 81 or the buffer link 811. In actual operation, when the speed of the outermost layer of the consumable roll gradually slows down, it will squeeze the buffer roller 81 to move towards the fourth position 83. When the buffer roller 81 moves to the fourth position 83, the detection unit 84 is triggered to control the feeding drive 12 to increase the feeding speed, thereby preventing the consumable from being torn. As the feeding speed of the feeding drive 12 increases, the buffer roller 81 gradually resets to the third position 82 under the drive of the buffer reset drive 85, achieving material storage buffering. This continues until the speed of the outermost layer of consumable roll is again slower than the machine's bubble wrap conveying speed and bubble wrap production speed, triggering the material storage buffering again. This invention further incorporates a film buffer module 8 for material storage buffering, effectively preventing the consumable from tearing during machine operation and ensuring the normal operation of the equipment.
[0070] Additionally, in some possible implementations, a guide roller 86 is further included downstream of the feeding module 1. Specifically, refer to... Figure 4 As shown, the guide roller 86 is positioned below the film buffer module 8. After passing over the guide roller 86, the consumable material continues to be conveyed downstream in the direction required for feeding into the inflation module 2. In the overall equipment, after being guided by the guide roller 86, the output position of the guide roller 86, the input position of the consumable quantity detection module 4, the input position of the inflation module 2, the input position of the heating module 5, and the inlet 72 of the separation module 7 are all on the same plane. This ensures smoother operation of the consumable material during the overall equipment operation, prevents material deviation, avoids affecting the normal operation of subsequent modules, and eliminates the need for a correction module, thus reducing the overall equipment cost. It should be noted that "on the same plane" here does not refer to an absolute plane, but rather to an approximate plane, ensuring smoother operation of the consumable material during the overall equipment operation.
[0071] During operation, the consumable material is conveyed via the heating wheel 51 of the heating module 5. The consumable material is released from the feeding rod 11 of the feeding assembly, inflated by the inflation module 2, and then heat-sealed in the heating module 5. Afterward, it passes through the detection module 61 and enters the separation module 7, continuously being conveyed towards the outlet 73. When the detection module 61 determines the position where the bubble wrap needs to be torn, it controls the entire equipment to stop operating and controls the clamping module 62 to clamp the bubble wrap. Simultaneously, it controls the separation module 7 to continue operating after a preset interval. At this time, the bubble wrap between the clamping module 62 and the separation module 7 is torn apart by the pulling force of the separation module 7, completing the bubble wrap separation process.
[0072] When the equipment also includes a feeding drive 12, a lifting drive 53, a sealing module 3, a consumable quantity detection module 4, a film buffer module 8, and a guide roller 86, during operation, the consumable first bypasses the buffer roller 81 of the film buffer module 8, then bypasses the guide roller 86, passes through the opening structure 44 of the consumable quantity detection module 4, then through the paddle structure 41, enters the inflation module 2, then passes through the sealing module 3, then enters the heating module 5, and finally passes through the detection module 61 into the separation module 7, continuously being conveyed to the discharge port 73. When the detection module 61 and the consumable quantity detection module 4 work together to determine the position where the bubble wrap is to be torn, the entire equipment stops operating in conjunction with the lifting drive 53, lifts the heating roller 51, controls the clamping module 62 to clamp the bubble wrap, and simultaneously controls the separation module 7 to continue operating after a preset interval. At this time, the bubble wrap between the clamping module 62 and the separation module 7 will be torn off under the pulling of the separation module 7, completing the bubble wrap separation process.
[0073] This utility model's integrated bubble wrap inflation and separation device uses a feeding assembly to feed the material, followed by inflation of the material by the inflation module 2 to form bubble wrap. The heating module 5 then heat-seals the opening of the bubble wrap, creating a complete and continuous bubble wrap product. The bubble wrap product continues to be conveyed to the separation module 7 until the tearing position is determined. At this point, the clamping drive 64 of the clamping module 62 moves the clamping member 63 to clamp the bubble wrap. Simultaneously, the separation module 7 stops until the clamping module 62 has gripped the bubble wrap, then resumes operation, working in conjunction with the clamping module 62 to tear the bubble wrap. The torn and separated bubble wrap is then conveyed to the discharge port 73 as the separation module 7 operates. Furthermore, the inclusion of a thin film buffer module 8 and the active feeding configuration of the feeding module 1 effectively prevents the material from breaking during bubble wrap production. Because the separation module 7 is integrated into the overall equipment, its conveying speed can match the overall equipment's feeding speed and bubble wrap production speed, eliminating the need for an additional wire mesh system for material storage. This utility model's integrated bubble wrap inflation and separation device combines bubble wrap inflation and separation functions. It cleverly utilizes the coordinated operation of the detection module 61, clamping module 62, and separation module 7 to integrate the inflation and separation functions into the overall equipment. This effectively reduces the production and assembly costs of the entire system and avoids the safety hazards associated with placing the bubble wrap inflator and separator at high positions in existing systems.
