Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging material production equipment technology, and in particular to a bubble film separation device. Background Technology
[0002] Currently, bubble wrap is frequently used for packaging various items and cartons. Existing bubble wrap requires workers to first tear off the appropriate number of sheets based on the size of the item before packing. Before tearing, workers must confirm the tear length. For larger items requiring more sheets, this necessitates considerable time and effort to accurately determine the required number of sheets. Furthermore, when using biodegradable paper-plastic film, the material's properties make it prone to tearing along the perforated lines, requiring extreme care and resulting in low packing efficiency.
[0003] At the same time, since the film is torn manually, the consistency of the number of film pieces torn off cannot be guaranteed. The number of film pieces will likely be too many or too few. Too many film pieces will lead to waste of film, while too few film pieces may result in inadequate packaging of goods, causing damage to goods during transportation and causing certain losses to customers.
[0004] Existing technologies include some bubble wrap separation devices, such as the device disclosed in patent US7571589B2. However, this device can only be used with bubble wrap the width of a single bubble. It is not suitable for bubble wrap with a wider width (such as four or more bubbles arranged side by side in a row). If the device needs to be modified, its overall width needs to be increased to accommodate larger bubble wrap sizes. To make the modified device suitable for more bubble wrap sizes, the overall width of the device must be increased as much as possible, ensuring that the width of the bubble wrap does not exceed the width of the device. This inevitably leads to an increase in the overall size of the device, which occupies a lot of space and also affects the stability of its use. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a bubble film separation device. It is applicable to bubble films of different widths and can significantly reduce the size of the equipment.
[0006] According to one aspect of the present invention, a shaped bubble film separation device is provided, comprising:
[0007] The frame has a feed inlet and a discharge outlet. A first transmission assembly and a second transmission assembly are arranged in the middle of the frame. The second transmission assembly is located downstream of the first transmission assembly. The frame is covered with an outer shell.
[0008] A support frame is installed on the outside of the feed inlet on the machine frame. The support frame includes a support part and is also provided with an adjustment structure for adjusting the width of the support part and the relative position between the support part and the feed inlet.
[0009] The first transmission component and the second transmission component have a first working condition and a second working condition. The first working condition is set such that the first transmission component and the second transmission component are configured to transmit the bubble film at the same speed along a first direction. The second working condition is set such that the first transmission component is configured to transmit the bubble film along a second direction, and the second transmission component is configured to transmit the bubble film along the first direction. The first direction is the direction from the inlet to the outlet, and the second direction is the direction from the outlet to the inlet.
[0010] The control module is used to control the operation of the first transmission component and the second transmission component.
[0011] This invention relates to a bubble wrap separation device. A control module controls a first and second transmission assembly on the frame to drive and tear the bubble wrap. A support frame is also provided on the frame, ensuring that the frame width does not need to exceed the width of the bubble wrap. Furthermore, in this invention, the control module controls the operation of the first and second transmission assemblies to tear the bubble wrap using a reverse tearing method, ensuring complete separation and preventing incomplete separation due to excessive bubble wrap width. Specifically, during operation, the upstream bubble wrap is supported by the support frame, keeping the bubble wrap near the inlet as parallel as possible to the bubble wrap inside the device, ensuring effective separation and preventing incomplete separation. Once the bubble wrap is torn, the bubble wrap near the outlet has already been separated and does not need to be torn again, allowing any excessively wide portion to hang freely without support. An outer shell is provided on the outside of the frame to protect the internal structure, thereby extending the device's lifespan.
[0012] In some embodiments, both the first transmission assembly and the second transmission assembly are configured as transmission belt assemblies including a first transmission belt and a second transmission belt, with portions of the first transmission belt and the second transmission belt abutting each other and their directions of movement being set to opposite for clamping the bubble film transmission.
[0013] Both the first transmission component and the second transmission component are disposed on one side of the frame, and the frame is also provided with an accommodating space.
[0014] Therefore, by setting it up in this way, the conveyor belt assembly only contacts the middle part of the bubble wrap to drive the bubble wrap. At the same time, the two conveyor belt parts of the conveyor belt assembly abut against each other, so as not to contact the bubble part in the bubble wrap. The excess bubble wrap can be placed in the accommodating space and move together with the part of the bubble wrap that contacts the conveyor belt assembly, thereby reducing the structural complexity of the conveyor belt assembly and effectively reducing the width of the conveyor belt assembly.
[0015] In some embodiments, the support frame includes a support body connected to the frame, a first support member is provided in the middle of the support body, and the adjustment structure includes a first stop and a second stop slidably disposed on the first support member, with a support portion formed at the position on the first support member between the first stop and the second stop.
[0016] Therefore, by using the first and second blocks, the portion of the first support member that contacts the bubble film can be adjusted, thereby limiting the width of the bubble film and limiting its position, ensuring that the bubble film's running path and position are correct, and thus ensuring the stability of the operation when separating the bubble film.
[0017] In some embodiments, the first support is a roller rotatably mounted on the support body.
[0018] Therefore, by using this configuration, the roller can be used to reduce the friction between the bubble wrap and the first support, thus avoiding affecting the integrity of the bubble wrap.
[0019] In some embodiments, the support body is further provided with a second support member arranged parallel to the first support member, and the first block and the second block are simultaneously slidably disposed on the first support member and the second support member.
[0020] Therefore, with this configuration, the second support can be used to further support the bubble film, so that the discharge direction of the bubble film production equipment can be opposite to the infeed direction of the equipment of this invention. At the same time, a gap can be formed between the second support and the first support to prevent the bubble film from piling up and entering the feed port of the equipment.
[0021] In some embodiments, a head-finding component is provided between the first transmission component and the second transmission component. The head-finding component is a photoelectric sensor and is oriented toward the bubble membrane to determine whether the end of the bubble membrane has been conveyed out of the first transmission component.
[0022] Therefore, with this setup, the end of the bubble membrane can be identified using a photoelectric sensor. Since the end of the bubble membrane will be conveyed towards the feed inlet during the second working condition, it is necessary to redetermine the position of the end of the bubble membrane in order to further determine the timing of the subsequent second working condition bubble membrane separation.
[0023] In some embodiments, an antistatic brush is provided at the discharge port.
[0024] Therefore, this setting can eliminate static electricity from the bubble wrap, preventing the separated bubble wrap from sticking to the equipment due to static electricity and not falling off.
[0025] In some embodiments, a stopping component is provided at the outlet, which is used to apply clamping pressure to the bubble film so that the bubble film is clamped and stopped at the outlet.
[0026] Therefore, this setup allows the stop-feed component to clamp the separated bubble wrap, preventing it from flying out of the equipment from the outlet and making it easier for users to pick up the separated bubble wrap.
[0027] In some embodiments, the stopping assembly includes a clamping plate and a brush assembly. The clamping plate is disposed on a first side of the discharge port and parallel to the discharge direction of the discharge port. The brush assembly is disposed on the side of the discharge port opposite to the first side. The distance between the end of the brush assembly facing the clamping plate and the clamping plate is not greater than the thickness of the bubble film.
[0028] Therefore, this setup allows the bubble wrap to be held in place by a brush and a clamping plate. The brush has good deformation properties and is less likely to affect the shape of the bubble wrap.
[0029] In some embodiments, one side of the support is flush with the same side of the frame, and the width of the support is set to be not less than the width of the frame and not more than twice the width of the frame.
[0030] Therefore, this configuration ensures that all bubble wrap placed in the equipment can be clamped and driven by the first and second transmission components, thus ensuring the stability of the equipment's operation. Attached Figure Description

[0040] 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.
[0041] The present invention will now be described in further detail with reference to the accompanying drawings.
[0042] Figure 1 and Figure 2 The schematic diagram illustrates the overall structural composition of the bubble film separation device according to one embodiment of the present invention, with reference to... Figure 1 and Figure 2As shown, the forming bubble film separating device of this utility model includes a frame 1, which has an inlet 11 and an outlet 12. A first transmission component 21 and a second transmission component 22 are arranged in the middle of the frame 1. The second transmission component 22 is located downstream of the first transmission component 21, and the end of the first transmission component 21 and the beginning of the second transmission component 22 are connected. This allows the bubble film to pass through the inlet 11, the first transmission component 21, the second transmission component 22, and the outlet 12 in sequence as it passes through the frame 1. The connection of the end of the first transmission component 21 and the beginning of the second transmission component 22 does not mean that the end of the first transmission component 21 and the beginning of the second transmission component 22 are completely seamlessly joined, but rather that they are arranged sequentially with appropriate gaps between them. The first transmission component 21 and the second transmission component 22 have a first working condition and a second working condition. The first operating condition is the conveying of bubble wrap. Both the first transmission assembly 21 and the second transmission assembly 22 are configured to convey the bubble wrap at the same speed along a first direction, which is from the inlet 11 to the outlet 12, thus achieving forward conveying of the bubble wrap. The second operating condition is the separation of bubble wrap. The first transmission assembly 21 is configured to convey the bubble wrap along a second direction, and the second transmission assembly 22 is configured to convey the bubble wrap along the first direction, which is from the outlet 12 to the inlet 11, thus achieving reverse conveying of the bubble wrap. When the first operating condition is achieved, the first transmission assembly 21 and the second transmission assembly 22 move synchronously at the same speed, enabling forward conveying of the bubble wrap. When the second operating condition is achieved, the first transmission assembly 21 moves in reverse, and the second transmission assembly 22 moves in forward, causing the bubble wrap to tear apart between the first transmission assembly 21 and the second transmission assembly 22, thereby achieving bubble wrap separation. The integrally formed bubble film separation device also includes a control module. The control module controls the operation of the first transmission component 21 and the second transmission component 22. It can be configured as a circuit board equipped with a control chip (such as a microcontroller chip). The control module is connected to the drive component that drives the first transmission component 21 and the second transmission component 22 to control their operation. (Refer to...) Figure 1 As shown, in some embodiments, the frame 1 may be provided with an outer shell 16 to protect the internal structure of the frame 1.
[0043] Reference Figure 1 and Figure 2As shown, the frame 1 is also equipped with a support frame 3, specifically located outside the feed inlet 11 on the frame 1. The support frame 3 is used to support the bubble film before it enters the frame 1. It includes a support portion 33, and the support frame 3 is also equipped with an adjustment structure 4 for adjusting the width of the support portion 33 and the relative position between the support portion 33 and the feed inlet 11. By providing the support frame 3, when it is necessary to separate a wider bubble film, as the bubble film passes through the frame 1, part of the bubble film will extend into the frame 1 and be driven by the first transmission component 21 and the second transmission component 22, while the other part of the bubble film will extend outside the frame 1 and be supported by the support frame 3, reducing the impact of the bubble film's own shape change during transmission and separation. By adjusting the width of the support portion 3 for supporting the bubble film, the width of the support portion 33 can be adaptively changed according to the different widths of bubble film to be separated. Adjusting the width of the support portion 33 to correspond to the width of the bubble film can limit the position of the bubble film, thereby preventing it from shifting when passing through the overall device and affecting the separation effect. At the same time, adjusting the relative position between the support portion 33 and the feed inlet 11 can adjust the size of the bubble film extending into the frame 1 and the size protruding from the frame 1.
[0044] The structure of the first transmission assembly 21 and the second transmission assembly 22 can be implemented as a conveyor belt assembly. The conveyor belt drives the movement of the bubble film, thus achieving bubble film transmission. The conveyor belt assembly includes a first conveyor belt 23 and a second conveyor belt 24, which are arranged opposite to each other and partially abut each other. Their directions of movement are set in opposite directions for clamping and transmitting the bubble film. Both the first conveyor belt 23 and the second conveyor belt 24 are driven by a combination of a drive wheel 25 and a driven wheel 26. Since the first conveyor belt 23 and the second conveyor belt 24 rotate synchronously, the conveyor belt assembly can achieve synchronous and same-speed rotation of the drive wheels 25 of the first conveyor belt 23 and the second conveyor belt 24 through the transmission between the drive motor, gears, pulleys, and belts. For specific details, refer to the structural settings of related transmission belt drive mechanisms in the prior art; this part will not be described in detail here.
[0045] In some possible implementations, both the first transmission assembly 21 and the second transmission assembly 22 are disposed on one side of the frame 1, and the frame 1 is also provided with an accommodating space 13. Specifically, refer to... Figure 4As shown, in this embodiment, the conveyor belt widths of the first transmission assembly 21 and the second transmission assembly 22 are set to be relatively small, such that the conveyor belt width is not greater than the spacing between adjacent bubbles in the width direction of the bubble film. This allows the abutting portions of the first conveyor belt 23 and the second conveyor belt 24 to clamp the spacing between adjacent bubbles in the width direction of the bubble film, thereby driving the bubble film to move. When the bubble film is clamped and moved, the portion of the bubble film facing inward towards the frame 1 can be placed within the receiving space 13 to prevent excessive sagging due to gravity, which would affect the transmission and separation of the bubble film. The portion of the bubble film facing outward towards the frame 1 can be supported by the support frame 3, ensuring that at least the section of the bubble film near the feed inlet 11 is supported, preventing any impact on the transmission and separation of the bubble film. (Refer to...) Figure 4 As shown, the accommodating space 13 is disposed inside the frame 1. An upper plate 14 and a lower plate 15 are disposed inside the frame 1. The upper plate 14 is disposed above the conveyor belt assembly, and the lower plate 15 is disposed below the conveyor belt assembly. The space between the upper plate 14 and the lower plate 15 forms the accommodating space 13. (Refer to...) Figure 2 As shown, the first transmission assembly 21 and the second transmission assembly 22 are disposed on one side of the frame 1, and the drive structure of the first transmission assembly 21 and the second transmission assembly 22 is disposed on opposite sides of the frame 1.
[0046] The support frame 3 may include a support body 34, which is connected to the frame 1 and disposed outside the feed inlet 11 on the frame 1. A first support member 31 is provided on the support body 34, forming a support portion 33 to support the bubble film. The adjustment structure 4 includes a first stop 41 and a second stop 42 slidably disposed on the first support member 31. The first stop 41 and the second stop 42, through their sliding arrangement on the first support member 31, limit the two sides of the portion of the first support member 31 used to support the bubble film, thereby forming the support portion 33 at the position on the first support member 31 between the first stop 41 and the second stop 42. Furthermore, to reduce the frictional impact on the bubble film when it passes through the first support member 31, thus preventing wear, the first support member 31 may be configured as a roller. (Refer to...) Figure 1 and Figure 2 As shown in the figure Figure 1 and Figure 2In the illustrated embodiment, the support body 34 forms a horizontal "C-shape," with one side flush with the same side on the frame 1. The first support member 31 is a roller, rotatably connected to both ends of the support body 34. A first stop 41 and a second stop 42 are slidably disposed on the first support member 31 to form a support portion 33. By dynamically adjusting the positions of the first stop 41 and the second stop 42, the width of the support portion 33 and its relative position to the feed inlet 11 can be adjusted. Additionally, the first support member 31 may be provided with graduations for user adjustment. Specifically, the width of the support portion 33 is set to be no less than the width of the frame 1 and no more than twice the width of the frame 1. This design ensures that regardless of the relative position of the support portion 33 to the feed inlet 11, the bubble wrap placed in the equipment can be clamped and driven by the first transmission component 21 and the second transmission component 22, ensuring the stability of the equipment operation.
[0047] Additionally, in some possible embodiments, the support body 34 may also be provided with a second support member 32 arranged parallel to the first support member 31, and the first stop block 41 and the second stop block 42 are configured to slide simultaneously on the first support member 31 and the second support member 32. Specifically, refer to Figure 2 As shown, in Figure 2 In the illustrated embodiment, the second support member 32 is disposed above the first support member 31 and is configured as a connecting rod, with both ends of the connecting rod fixedly mounted on the bracket body 34. The first stop block 41 and the second stop block 42 are simultaneously slidably disposed on the first support member 31 and the second support member 32, and clamping structures are provided at the connection points of the first stop block 41 and the second stop block 42 with the second support member 32 to fix their positions. At this time, a scale can be set on the second support member 32. Specifically, the clamping structure includes a first clamping block and a second clamping block, with the second support member 32 clamped between the first clamping block and the second clamping block. The first clamping block and the second clamping block are connected by bolts, and tightening the bolts clamps the second support member 32, thereby fixing the positions of the first stop block 41 and the second stop block 42. By adding a second support member 32, the bubble film can be further supported around the second support member 32. This ensures that the bubble film can be supported by the support frame 3 and fed into the inlet 11 of the bubble film separation equipment regardless of the direction or angle from which it exits during preparation. Simultaneously, a rectangular inlet structure 35 is formed between the first support member 31 and the second support member 32. This ensures that the bubble film must pass through this inlet structure 35 before entering the equipment from the inlet 11, thus preventing the bubble film from folding and affecting its entry into the equipment and its separation.
[0048] To better determine the length of the separated bubble film, a head-finding assembly 5 can be provided on the frame 1 to determine the current position of the bubble film within the frame 1. Specifically, the head-finding assembly 5 can be configured as a photoelectric sensor, positioned between the first transmission assembly 21 and the second transmission assembly 22, and facing the bubble film, to determine the length of the separated bubble film when the control device performs the second operating condition. For example, referring to... Figure 3 As shown, in Figure 3 In the illustrated embodiment, the head-finding component 5 is configured as a photoelectric sensor and positioned between the first transmission component 21 and the second transmission component 22. Since the device operates at a constant speed during the first working condition, the head-finding component 5 senses the end of the bubble membrane when transmission begins. Based on the transmission time and speed, the length traveled by the bubble membrane can be determined, thus enabling the determination of the length of the bubble membrane separated during the second working condition. Alternatively, the length of the bubble membrane separated during the second working condition can also be determined by monitoring the number of motor rotations and the length of the bubble membrane traveled per rotation.
[0049] Additionally, an antistatic brush 6 can be installed at the discharge port 12 of the frame 1. The antistatic brush 6 removes static electricity from the discharged bubble wrap, preventing the separated bubble wrap from adhering to the equipment due to static electricity and failing to fall off on its own. For details, refer to... Figure 1 As shown, in Figure 1 In the illustrated embodiment, the antistatic brush 6 is positioned above the outlet 12 with its bristles hanging down, allowing the bubble film exiting the outlet 12 to contact the antistatic brush and thus remove static electricity from the exiting bubble film. The length of the antistatic brush is the same as the width of the outlet 12, so that the bubble film exiting the outlet 12 can be removed from static electricity simultaneously.
[0050] In some possible implementations, a stopping component may also be provided at the discharge port 12 of the overall device. This stopping component applies clamping pressure to the bubble wrap, causing it to be clamped and stopped at the discharge port 12 for easy removal by the user. Specifically, the stopping component may include a clamping plate 72 and a brush assembly 71. The clamping plate 72 is disposed on the first side of the discharge port 12 and parallel to the discharge direction of the discharge port 12. The brush assembly 71 is disposed on the side of the discharge port 12 opposite to the first side, thus the clamping plate 72 and the brush assembly 71 are positioned opposite each other to clamp the bubble wrap exiting from the discharge port 12. (Refer to...) Figure 1 As shown, in Figure 1In the illustrated embodiment, the clamping plate 72 is located at the lower part of the discharge port 12, and its length is the same as the width of the discharge port 12. The brush assembly 71 is located at the upper part of the discharge port 12, and is only located at the position corresponding to the position of the second transmission assembly 22 at the discharge port 12, thereby reducing the number of brush assemblies 71. The distance between the end of the brush assembly 71 facing the clamping plate 72 and the clamping plate 72 is set to be no greater than the thickness of the bubble film, so that the good deformation performance of the bristles of the brush assembly 71 can be utilized to clamp the bubble film through the deformation of the bristles and the clamping plate 72. At the same time, since the bristles are relatively soft, they are less likely to affect the shape of the bubble film. The clamping plate 72 can be set as a collision protection plate made of polyurethane, which can alleviate the injury to the user when colliding with the clamping plate 72 during use, thereby improving the safety of the equipment. It is understood that the setting of the material stopping component and the setting of the electrostatic brush in this embodiment can be set simultaneously without affecting each other. The setting of the clamping plate 72 can also enable the electrostatic brush to make better contact with the bubble film and remove static electricity from the bubble film.
[0051] The bubble wrap separation device of this invention uses a first transmission component 21 and a second transmission component 22 on a frame 1 to drive and tear the bubble wrap. A support frame 3 is also provided on the frame 1, ensuring that the width of the frame 1 does not need to exceed the width of the bubble wrap. Furthermore, since this invention separates the bubble wrap by tearing in reverse, it ensures complete separation during tearing, preventing incomplete separation due to excessive bubble wrap width. Specifically, during operation, the upstream bubble wrap is supported by the support frame 3, allowing the bubble wrap near the inlet 11 to remain as parallel as possible to the bubble wrap inside the device, ensuring effective separation and preventing incomplete separation. Once the bubble wrap is torn, since the bubble wrap near the outlet 12 has already been separated, it does not need to be torn again, allowing any excessively wide portion to hang freely without support.
[0052] In use, the forming bubble film separating device of this utility model first adjusts the width of the support portion 33 on the support frame 3 according to the width of the bubble film to be separated. Then, the bubble film wraps around the first support member 31 and the second support member 32 on the support frame 3, passes through the inlet structure 35 formed between the first support member 31 and the second support member 32, and passes through the support portion 33 to be put into the feed port 11. When the equipment is started, the first working condition is executed first, so that the first transmission component 21 and the second transmission component 22 transmit the bubble film to the discharge port 12 at the same speed. During transmission, the bubble film passes between the first transmission component 21 and the second transmission component 22 and is detected by the head-finding component 5 to start calculating the length of the transmitted bubble film. When the preset threshold standard is reached, the head-finding component 5 will send a signal to control the operation of the equipment, so that the current working condition changes from the first working condition to the second working condition. After executing the second working condition, the first transmission component 21 and the second transmission component 22 will operate in opposite directions to tear and separate the bubble wrap. The separated bubble wrap on the second transmission component 22 side will continue to be conveyed to the outlet 12, while the bubble wrap on the first transmission component 21 side will be conveyed a distance towards the inlet 11. After the separated bubble wrap exits from the outlet 12, it will pass through the antistatic brush 6 for antistatic treatment and stop at the outlet 12 under the clamping of the brush component 71 and the clamping plate 72, which the user can directly pick up. When it is necessary to separate the bubble wrap again, the first working condition will be executed again, so that the bubble wrap is conveyed from the first transmission component 21 to the second transmission component 22 and conveyed towards the outlet 12. At this time, it will be detected again after passing through the head-finding component 5 to continue to calculate the length of the conveyed bubble wrap.
[0053] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
