Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a bubble bag cutting device. Background Technology

[0002] In the field of packaging material processing, bubble wrap is widely used for packaging protection of various products due to its excellent cushioning and shockproof properties.

[0003] Current bubble wrap cutting operations use a cutting mechanism that moves reciprocally in a fixed direction. However, the existing solution requires the operator to first compress the bubble wrap, and then move to another position to perform the cutting operation, or for two operators to perform the compressing and cutting operations sequentially. The process is cumbersome and inconvenient. Utility Model Content

[0004] This invention provides a bubble bag cutting device to solve the technical problems of cumbersome bubble bag cutting process and inconvenient operation.

[0005] This utility model provides a bubble bag cutting device, which includes: frame; A roller mechanism, mounted on the frame, is used to load bubble bags to be cut; A cutting mechanism, mounted on the frame, is used to cut bubble wrap. The cutting mechanism includes a cutting bracket, a blade holder assembly, a first driving member, and a second driving member. The blade holder assembly is movably mounted on the cutting bracket in a first direction and a vertical direction. The driving ends of the first and second driving members are respectively connected to the blade holder assembly to drive the blade holder assembly to move in the first and vertical directions. A sensor element is mounted on the cutting bracket, and the sensor element is electrically connected to the first and second driving members respectively. A pressure bar mechanism is mounted on the frame. The pressure bar mechanism is used to compress the bubble bag before cutting. The pressure bar mechanism includes a pressure bar bracket and a pressure bar. The pressure bar is positioned toward the cutting mechanism and can be tilted on the pressure bar bracket. The pressure bar can cooperate with the sensor element. When the pressure bar presses the bubble bag, it can cooperate with the sensor element and trigger the sensor element, so that the first drive member and the second drive member drive the cutter assembly to move along the first direction and the vertical direction to cut the bubble bag.

[0006] In one embodiment of this utility model, the pressure rod mechanism further includes a limiting component, which includes a locking member and a compression spring. The locking member is movably disposed on the frame along a second direction and can be locked to the frame by fasteners. The two ends of the compression spring are respectively connected to the locking member and the pressure rod. The locking member can lock the position of the pressure rod and tighten it. The locking member is movable, making the tension of the locking member on the pressure rod adjustable, thereby making the pressure force of the pressure rod on the bubble bag adjustable. When the locking member moves away from the pressure rod, the tension of the compression spring on the pressure rod increases, thereby increasing the pressure force of the pressure plate on the bubble bag and improving the tightening effect. When the locking member moves closer to the pressure rod, the tension of the compression spring on the pressure rod decreases, and the pressure rod can move away from the bubble bag to reset. After the locking member is in place, it can be locked to the frame by fasteners, so that the pressure rod can maintain the pressure on the bubble bag, replacing manual operation of the pressure rod and simplifying the operation.

[0007] In one embodiment of this utility model, the number of limiting components is two sets, and they are respectively located on both sides of the frame along the second direction. The two sets of limiting components correspond to the two ends of the pressure rod, so that both ends and the middle of the pressure rod can have a better pressing effect on the bubble bag, thereby improving the overall pressing effect of the pressure rod on the bubble bag.

[0008] In one embodiment of this utility model, the pressure bar mechanism is located between the roller mechanism and the cutting mechanism along the second direction. Cutting the bubble bag after it has been compressed improves the cutting effect.

[0009] In one embodiment of this utility model, the pressure bar mechanism is movably mounted on the frame along a second direction. The position of the pressure bar mechanism can be adjusted according to the required cutting length of the bubble bag. When it is necessary to increase the cutting length of the bubble bag, moving the pressure bar mechanism away from the roller mechanism can increase the pressing length of the bubble bag and facilitate operation.

[0010] In one embodiment of this utility model, the sensor element is a pressure sensor. When the pressure rod presses the bubble bag tightly, the outer periphery of the pressure rod can abut against the measuring end of the pressure sensor. Compared with other sensors, the pressure sensor can avoid the problem of the cutting mechanism being activated due to accidental contact by the pressure rod.

[0011] In one embodiment of this utility model, the blade holder assembly includes a blade holder and an annular cutter disposed on the blade holder. The annular cutter has a long blade length, enabling it to cut over a relatively large area. Even when the blade holder assembly fails to move into position for various reasons, it can still cut bubble wrap, making it convenient to use.

[0012] In one embodiment of this utility model, the blade holder assembly further includes a clamping unit for further compressing the bubble bag when the annular cutter cuts the bubble bag. The clamping unit is disposed on the blade holder and located on both sides of the annular cutter. The clamping unit includes a plurality of rolling bearings arranged along a first direction. The rolling bearings first clamp the bubble bag in the adjacent areas on both sides of the annular cutter, keeping the bubble bag flat and effectively eliminating wrinkles caused by uneven force during the cutting process. At the same time, the rolling bearings make rolling contact with the bubble bag, which, compared with the traditional fixed clamping method, reduces frictional damage to the surface of the bubble bag, ensuring that the cut bubble bag has neat edges and a flat surface, significantly improving the cutting quality and finished product qualification rate of the bubble bag.

[0013] In one embodiment of this utility model, the cutter support includes two opposing mounting plates and a guide shaft disposed between the two mounting plates. A linear bearing is sleeved on the guide shaft, and the cutter holder assembly is movably mounted on the linear bearing in a vertical direction. The linear bearing is capable of moving vertically on the cutter holder assembly, thereby enabling the cutter holder assembly to move vertically relative to the cutter support via the linear bearing.

[0014] In one embodiment of this utility model, the blade holder assembly is provided with a handle. This allows for manual operation of the blade holder assembly for cutting even in the event of a power outage, making it convenient to use.

[0015] The beneficial effects of this utility model are: 1. By setting up a pressure bar mechanism, the bubble bag can be pre-compressed before cutting, effectively preventing displacement and wrinkling of the bubble bag during the cutting process, thereby improving the cutting quality of the bubble bag; 2. The pressure bar, mounted on its support, can tilt and rotate to press the bubble wrap spread out on the frame. When the pressure bar rotates downwards to press the bubble wrap, it triggers a sensor element located on the cutter assembly. The sensor element drives a first and a second drive component, causing the cutter assembly to move downwards and along the cutting direction to cut the bubble wrap. Through the cooperation between the pressure bar and the sensor element, a single operator can complete the cutting operation by simply manipulating the pressure bar, eliminating the need for manual cutting and simplifying the bubble wrap cutting process, making the cutting operation much easier.

Detailed Implementation

[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] It's important to note that cutting bubble wrap differs from cutting ordinary packaging bags or plastic bags. Because of the numerous and dispersed air bubbles, bubble wrap is not perfectly flat even when laid out. During cutting, it's more prone to displacement and wrinkling; therefore, ordinary cutting equipment cannot be used for bubble wrap.

[0023] It should also be noted that the first direction refers to the axial direction of the roller mechanism 2, and the second direction refers to the unfolding direction of the bubble bag. The first and second directions are perpendicular to each other. The two sides of the frame 1 refer to the two sides of the frame 1 along the second direction, that is, the two sides of the frame 1 along the unfolding direction of the bubble bag.

[0024] Please see Figure 1 , Figure 1 A bubble bag cutting device provided in one embodiment of the present invention, such as Figure 1 As shown, it includes: Rack 1; Roller mechanism 2, mounted on frame 1, is used to load bubble bags to be cut; A cutting mechanism 3, mounted on the frame 1, is used to cut bubble wrap. The cutting mechanism 3 includes a cutting support 32, a blade holder assembly 31, a first driving member (not shown in the figure), and a second driving member (not shown in the figure). The blade holder assembly 31 is movably mounted on the cutting support 32 in a first direction and a vertical direction. The driving ends of the first driving member and the second driving member are respectively connected to the blade holder assembly 31 to drive the blade holder assembly 31 to move in the first direction and the vertical direction. A sensor element (not shown in the figure) is mounted on the cutting support 32, and the sensor element is electrically connected to the first driving member and the second driving member respectively. The pressure bar mechanism 4 is mounted on the frame 1. The pressure bar mechanism 4 is used to press the bubble bag before cutting. The pressure bar mechanism 4 includes a pressure bar bracket 42 and a pressure bar 41. The pressure bar 41 is positioned toward the cutter mechanism 3 and can be tilted on the pressure bar bracket 42. The pressure bar 41 can cooperate with the sensor element. When the pressure rod 41 presses the bubble bag, it can cooperate with the sensor element and trigger the sensor element, so that the first drive member and the second drive member drive the cutter assembly 31 to move along the first direction and the vertical direction to cut the bubble bag.

[0025] Specifically, the roller mechanism 2 includes a roller frame fixedly connected to both sides of the frame 1, a roller rotatably connected to the roller frame, and a bubble bag wrapped around the roller.

[0026] The first driving member drives the cutter assembly 31 to move along a first direction, and the second driving member drives the cutter assembly 31 to move along a second direction. The cutter assembly 31 moves vertically to reach the cutting height for cutting the bubble wrap, and then moves along the first direction to cut the bubble wrap. Both the first and second driving members can be motors, and they can be mounted on the frame 1 or the cutter support 32. The first and second driving members drive the cutter assembly 31 to move via transmission mechanisms, which can be gear, rack and pinion, or worm gear transmission structures, etc. Sensor elements are electrically connected to the first and second driving members, respectively, so that when the sensor elements are triggered, they can drive the first and second driving members to operate. The first and second driving members can operate sequentially or simultaneously, both of which can be achieved using existing technologies.

[0027] The opposite sides of the pressure rod bracket 42 are called the inner side, and the opposite sides are called the outer side. Two rotating plates are connected to both ends of the pressure rod 41, and these plates are hinged to the outer sides of the pressure rod bracket 42, allowing the pressure rod 41 to pitch and rotate on the bracket 42. The pressure rod 41 is positioned towards the cutter mechanism 3, and its pitch and rotation allow it to move closer to and further away from the cutter mechanism 3. The pressure rod 41 can cooperate with a sensor element; when the pressure rod 41 presses down on the bubble bag located on the frame 1, it triggers the sensor element. The sensor element can be a photoelectric sensor, a proximity sensor, or a pressure sensor, etc.

[0028] The beneficial effects of this embodiment: 1. By setting up the pressure bar mechanism 4, the bubble bag can be pre-compressed before cutting, which effectively prevents the bubble bag from shifting or wrinkling during the cutting process, thereby improving the cutting quality of the bubble bag; 2. The pressure rod 41, mounted on the pressure rod bracket 42, can tilt and rotate to press the bubble wrap spread on the frame 1. When the pressure rod 41 rotates downward to press the bubble wrap, it triggers a sensor element located on the cutter assembly 31. The sensor element drives the first and second drive components, causing the cutter assembly 31 to move downward and along the cutting direction to cut the bubble wrap. Through the cooperation between the pressure rod 41 and the sensor element, an operator can complete the cutting operation by simply operating the pressure rod 41, eliminating the need for manual cutting and simplifying the bubble wrap cutting process, making the bubble wrap cutting operation more convenient.

[0029] In some implementations, such as Figure 1 and Figure 2As shown, the pressure rod mechanism 4 also includes a limiting component 43, which includes a locking member 431 and a compression spring 432. The locking member 431 is movably disposed on the frame 1 along the second direction and can be locked on the frame 1 by fasteners. The two ends of the compression spring 432 are respectively connected to the locking member 431 and the pressure rod 41.

[0030] Specifically, the locking member 431 can move along the side of the frame 1 in the second direction and is secured to the frame 1 by fasteners after it is in place. The fasteners can be bolts, which are threadedly connected to the locking member 431 and cooperate with each other. The two ends of the compression spring 432 are respectively connected to the bottom ends of the pressure plate (not shown in the figure) on the locking member 431 and the pressure rod 41. The compression spring 432 can pull the locking member 431 and the pressure plate together, thereby pulling the pressure rod 41 so that the pressure rod 41 can press the bubble bag. The locking member 431 can lock the position of the pressure rod 41 and pull the pressure rod 41 tight. The locking member 431 can move, so that the pulling force of the locking member 431 on the pressure rod 41 is adjustable, thereby making the pressing force of the pressure rod 41 on the bubble bag adjustable. When the locking member 431 moves away from the pressure rod 41, the pulling force of the compression spring 432 on the pressure rod 41 increases, thereby increasing the pressing force of the pressure plate on the bubble bag and improving the pressing effect. When the locking element 431 approaches the pressure rod 41, the tension of the spring 432 on the pressure rod 41 decreases, and the pressure rod 41 can move away from the bubble bag and reset. After the locking element 431 is in place, it can be locked onto the frame 1 by fasteners, so that the pressure rod 41 can maintain the pressure on the bubble bag, which replaces manual operation of the pressure rod 41 and makes the operation simple.

[0031] In some embodiments, the number of limiting components 43 is two sets, and they are located on both sides of the frame 1 along the second direction.

[0032] The two sets of limiting components 43 respectively correspond to the two ends of the pulling rod 41, so that both ends and the middle of the rod 41 can have a better pressing effect on the bubble bag, thereby improving the overall pressing effect of the rod 41 on the bubble bag.

[0033] In some implementations, such as Figure 1 and Figure 2 As shown, the pressure bar mechanism 4 is located between the roller mechanism 2 and the cutter mechanism 3 along the second direction.

[0034] The pressure bar mechanism 4 is positioned between the roller mechanism 2 and the cutting mechanism 3, so that after the bubble bag is unfolded, it is first pressed tightly onto the frame 1 by the pressure bar mechanism 4, and then the cutting mechanism 3 cuts it. Cutting the bubble bag after it has been pressed tightly improves the cutting effect.

[0035] In some embodiments, the pressure bar mechanism 4 is movably mounted on the frame 1 along a second direction.

[0036] The position of the pressure bar mechanism 4 can be adjusted according to the required cutting length of the bubble bag. When it is necessary to increase the cutting length of the bubble bag, the pressure bar mechanism 4 can be moved away from the roller mechanism 2, which can increase the pressing length of the bubble bag and facilitate operation.

[0037] In some embodiments, the sensor element is a pressure sensor, and the outer periphery of the pressure rod 41 can abut against the measuring end of the pressure sensor when the pressure rod 41 presses the bubble bag.

[0038] When the pressure rod 41 compresses the bubble bag, its outer wall presses against the measuring end of the pressure sensor, triggering the sensor and driving the first and second driving components to operate. Compared to other sensors, the pressure sensor avoids the problem of the cutting mechanism 3 being activated due to accidental activation of the pressure rod 41.

[0039] In some implementations, such as Figures 1 to 3 As shown, the blade holder assembly 31 includes a blade holder 311 and an annular cutter 312 disposed on the blade holder 311.

[0040] The ring cutter 312 has a long blade, allowing it to cut over a wide area. Even when the cutter holder assembly 31 fails to move into position for various reasons, it can still cut bubble wrap, making it convenient to use.

[0041] In some implementations, such as Figures 1 to 3 As shown, the blade holder assembly 31 also includes a clamping unit for further compressing the bubble bag when the annular cutter 312 cuts the bubble bag. The clamping unit is disposed on the blade holder 311 and located on both sides of the annular cutter 312. The clamping unit includes a plurality of rolling bearings 313 arranged along a first direction.

[0042] Multiple rolling bearings 313 are located on both sides of the annular cutter 312 along its thickness direction, with each bearing 313 on the same side spaced apart. The rolling bearings 313 are vertically positioned, and their outer circumferences can contact and roll on the bubble bag. The bottom height of the rolling bearings 313 is higher than the bottom height of the annular cutter 312, allowing them to compress the bubble bag before the cutter contacts it. The rolling bearings 313 first compress the bubble bag in the adjacent areas on both sides of the annular cutter 312, keeping the bubble bag flat and effectively eliminating wrinkles caused by uneven force during cutting. Simultaneously, the rolling contact between the rolling bearings 313 and the bubble bag reduces frictional damage to the bubble bag surface compared to traditional fixed compression methods, ensuring neat edges and a smooth surface after cutting, significantly improving the cutting quality and finished product yield.

[0043] In some implementations, such as Figure 2As shown, the cutter holder 32 includes two oppositely arranged mounting plates and a guide shaft 321 disposed between the two mounting plates. A linear bearing 314 is sleeved on the guide shaft 321, and the linear bearing 314 is movably disposed on the cutter holder assembly 31 in the vertical direction.

[0044] The guide shaft 321 is arranged along a first direction, and the linear bearing 314 is slidable on the guide shaft 321 along its axial direction, thereby allowing the tool holder assembly 31 to slide on the guide shaft 321 along with the linear bearing 314. The linear bearing 314 is also slidable on the tool holder assembly 31 in a vertical direction, allowing the tool holder assembly 31 to move vertically relative to the cutter support 32 via the linear bearing 314.

[0045] In another implementation, such as Figure 3 As shown, a slider 316 is provided on the linear bearing 314, and a linear guide rail 315 extending in the vertical direction is provided on the tool holder 311. The slider 316 can slide within the linear guide rail 315.

[0046] In some embodiments (not shown in the figures), the sensor element can also be mounted on the cutter holder 311. The advantage of this arrangement is that when the pressure rod 41 presses down on the bubble bag, it directly abuts against the cutter holder 311, achieving close coordination between the pressure rod 41 pre-pressing the bubble bag and the cutting function. While applying pre-tension to flatten and fix the bubble bag, the pressure rod 41 also provides additional support and positioning for the cutter holder 311, effectively reducing the shaking of the cutter holder 311 during the cutting process and further enhancing the stability of the cutting process.

[0047] In some implementations, such as Figure 3 As shown, a handle 317 is provided on the cutter holder assembly 31. By providing the handle 317, the cutter holder assembly 31 can be manually operated for cutting even when the power is off, making it convenient to use.

[0048] In some implementations, such as Figure 1 As shown, the frame 1 is movable. Specifically, the frame 1 can be moved by providing casters 11 at the bottom. When needed, the frame 1 can be moved to any designated position, facilitating the use of this embodiment in conjunction with other equipment or mechanisms. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
