Description

Technical Field

[0001] This invention relates to the field of wrapping machine technology, and more particularly to an online bubble wrap wrapping machine. Background Technology

[0002] To prevent products stacked on pallets from collapsing or colliding during pallet transfer or storage, bubble wrap is typically used to wrap the stacked goods. However, existing bubble wrap wrapping machines lack a clamping structure when applying the tape, which can easily cause the bubble wrap to shift and result in misalignment of the tape. Therefore, we have designed an online bubble wrap wrapping machine.

[0003] Chinese invention patent CN201910080072.4 discloses a wrapping machine and a wrapping method, including a turntable, a wrapping device, and a corner protector feeding device for placing L-shaped corner protectors. A working area for the corner protector feeding device to operate is provided on the outer side of the turntable. The wrapping device is located on one side of the turntable and includes a column and a wrapping cylinder frame installed on the column. The working area has a center line passing through the center of the turntable and boundary lines on both sides of the center line that are parallel to the center line. The two boundary lines intersect the edge of the turntable at two points. Taking any one of the points as the starting point, two rays are drawn on both sides of the corresponding boundary line. One ray is located outside the working area and the angle between it and the corresponding boundary line is less than 40 degrees. The angle between the other ray and the corresponding boundary line is less than 80 degrees. The wrapping cylinder frame is located within the angle range formed by the two rays. The beneficial effects of the present invention are as follows: a wrapping machine is provided in which the working area of ​​the turntable, the corner protector feeding device and the wrapping device are set at a specific angle, which can safely and conveniently install corner protectors. However, the equipment has the following problems: firstly, the wrapping film does not have the function of smoothing and pressing the film during the wrapping process, so the adhesive tape cannot be accurately fixed after the film is cut. Secondly, it does not have the function of automatically transporting the stacked goods after the wrapping is completed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by incorporating a heating device, an ejector airbag, and a roller conveyor belt. This solves the technical problems of existing wrapping machines, such as the inability to automatically press the bubble film at the cut point, which easily leads to adhesive position misalignment, high energy consumption, and low wrapping efficiency due to the use of forklifts to handle and stack goods.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An online bubble wrap wrapping machine includes a lifting column, a support frame on the right side of the lifting column, a crossbar on the upper end of the support frame, a linear guide at the front end of the crossbar, two linear guide assemblies adapted to the surface of the linear guide, a cross connector at the front end of the right linear guide assembly, an automatic film cutting mechanism at the right end of the cross connector, and brush film covering mechanisms symmetrically arranged above and below the cross connector. An automatic pressure plate structure is located above the brush film covering mechanism, and a pneumatic actuator is located at the rear end of the automatic pressure plate structure.

[0007] As a preferred embodiment, the front end of the linear guide assembly on the left is provided with a rectangular connecting plate, and the upper and lower ends of the rectangular connecting plate are symmetrically provided with automatic adhesive tape mechanisms.

[0008] As a preferred embodiment, the automatic film-cutting mechanism includes a film-cutting frame, a film-coating roller shaft on the right side of the film-cutting frame, a heating wire at the front end of the film-cutting frame, a heating device at the upper end of the film-cutting frame, the heating device being electrically connected to the heating wire, and the rear end of the heating device abutting against the first gas chamber.

[0009] As a preferred embodiment, the pneumatic actuator includes a first gas chamber, with an inlet on the upper right side of the first gas chamber, an L-shaped isolation plate on the inner right side of the first gas chamber, air vents evenly distributed on the surface of the L-shaped isolation plate, and limestone in the space formed between the L-shaped isolation plate and the first gas chamber.

[0010] As a preferred embodiment, the front end of the first gas chamber is provided with two ejector air bladders, and a connecting pipe is provided between the ejector air bladders. The surface of the ejector air bladders is uniformly distributed with expansion and contraction corrugations, and the left end of the left ejector air bladder is connected to an exhaust pipe. The end of the exhaust pipe away from the ejector air bladder is provided with a first suction device, and the first suction device is connected to the second gas chamber.

[0011] As a preferred embodiment, the second gas chamber is provided with an outlet at its left end and a return pipe at its rear end. The end of the return pipe away from the second gas chamber is provided with a second suction device, and the right end of the second suction device is connected to the first gas chamber.

[0014] As a preferred embodiment, the lifting column is provided with a rotating disk at its front end, a transmission roller structure is provided at the upper end of the rotating disk, and roller transmission belts are symmetrically provided on the left and right sides of the rotating disk.

[0015] The beneficial effects of this invention are:

[0016] (1) In this invention, by setting up a heating device, on the one hand, the temperature of the heating wire is increased to realize the function of automatic heating wire membrane breaking, and on the other hand, the heat generated by its operation is transferred to the No. 1 gas chamber, which increases the temperature in the No. 1 gas chamber, thereby causing the carbon dioxide gas in the No. 1 gas chamber to expand due to heat, causing the limestone in the No. 1 gas chamber to decompose due to heat and produce carbon dioxide gas. The volume of carbon dioxide gas increases due to heat, causing the ejector airbag to fully expand, thereby causing the automatic pressure plate structure to be ejected, which plays the role of pressing the bubble membrane.

[0017] (2) In this invention, by setting telescopic corrugations on the ejector airbag, the expansion degree of the ejector airbag is increased, the ejection length of the ejector airbag is increased, and the possibility of damage to the ejector airbag is reduced, so that the automatic pressure plate structure has a good pressing effect.

[0018] (3) In this invention, by setting up a transmission roller structure and a roller conveyor belt, the automatic loading and unloading of stacked goods can be realized without the need to use a forklift for handling, thus speeding up the handling process.

[0019] In summary, this equipment has the advantages of simple structure, automatic pressing, and accurate adhesive application, and is especially suitable for the field of wrapping machine technology. Attached Figure Description

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1 to 6 As shown, this invention provides an online bubble wrap wrapping machine, including a lifting column 1, which provides installation space for the wrapping frame 13 and the control computer 12, and provides space for the wrapping frame 13 to move up and down. A support frame 2 is provided on the right side of the lifting column 1, increasing the height of the crossbeam 21 from the ground, so that the automatic film cutting mechanism 3, the brush film covering mechanism 4, and the automatic pressure plate structure 5 are at a suitable working height. A crossbeam 21 is provided at the upper end of the support frame 2, allowing the linear guide 22 to be installed stably and securely. The front end of the crossbeam 21 is provided with the linear guide 22, which is a linear guide rail controlled by the control computer 12. As a transmission element, it transmits motion and power, enabling different parts of the machine to work in coordination and complete various processing actions. It drives two linear guide assemblies 23 to move left and right. Two linear guide assemblies 23 are fitted onto the surface of the linear guide 22. A cross connector is provided at the front end of the right-side linear guide assembly 23. 24. The right end of the cross connector 24 is provided with an automatic film-cutting mechanism 3 to realize the function of automatic film cutting. The cross connector 24 is symmetrically provided with brush film-covering mechanisms 4. After the photoelectric detection of the goods is in place, the pneumatic actuator 10 moves forward, the automatic film-cutting mechanism 3 burns the bubble film, the brush film-covering mechanism 4 assists in wrapping the outer layer of broken film, the pneumatic actuator 10 performs film-adhesive action, the automatic adhesive tape mechanism 61 is pulled to the position, and the automatic adhesive tape mechanism 61 sticks the tape to the outer layer of bubble film and wraps the bubble film tightly. The brush film-covering mechanism 4 is provided with an automatic pressure plate structure 5 above it, which automatically presses the broken bubble film, so that the automatic adhesive tape mechanism 61 can accurately stick the tape at the broken film and prevent the bubble film from falling apart. The rear end of the automatic pressure plate structure 5 is provided with a pneumatic actuator 10, which drives the automatic pressure plate structure 5 to push forward to achieve the film-pressing effect.

[0030] Furthermore, such as Figure 3 As shown, the front end of the left-side linear guide assembly 23 is provided with a rectangular connecting plate 6, which fixes the linear guide assembly 23 and the automatic tape-adhesive mechanism 61 together. The upper and lower ends of the rectangular connecting plate 6 are symmetrically provided with the automatic tape-adhesive mechanism 61, which is a standard part. It automatically adheres the tape to the broken parts of the bubble wrap to prevent the bubble wrap from falling apart. The automatic tape-adhesive mechanism 61 is controlled by the control computer 12.

[0031] Furthermore, such as Figure 4As shown, the automatic film-cutting mechanism 3 includes a film-cutting frame 31, providing installation space for the coating roller 32, heating device 34, and heating wire 33. The coating roller 32 is located on the right side of the film-cutting frame 31. Bubble film conveyed from the wrapping film frame 13 is wound onto the coating roller 32 and then onto the stacked goods. The coating roller 32 serves to limit the position of the bubble film, ensuring it is within the effective range of the heating wire 33. The heating wire 33 is located at the front end of the film-cutting frame 31. The heating wire 33 generates high temperature under the action of the heating device 34, thereby achieving automatic film cutting. The heating device 34 is located at the upper end of the film-cutting frame 31. The heating device 34 is electrically connected to the heating wire 33. The operation of the heating device 34 enables the heating wire 33 to heat up rapidly. The heating device 34 is controlled by the control computer 12. The rear end of the heating device 34 abuts against the first gas chamber 35. The heat generated by the operation of the heating device 34 is transferred to the first gas chamber 35, causing the temperature inside the first gas chamber 35 to rise. The rear end of the first gas chamber 35 is provided with an oxygen pipe. The oxygen pipe is a one-way ventilation pipe. External oxygen enters the first gas chamber 35 through the oxygen pipe, which can promote the decomposition of limestone and also allow the carbon monoxide produced in the decomposition process to fully react with oxygen to form carbon dioxide.

[0032] Furthermore, such as Figure 5 As shown, the pneumatic actuator 10 includes a first gas chamber 35. An inlet 351 is located on the upper right side of the first gas chamber 35 to facilitate the addition of limestone. The first gas chamber 35 is filled with carbon dioxide gas, which exhibits thermal expansion and contraction. When the temperature inside the first gas chamber 35 rises, the volume of the carbon dioxide gas expands, causing the ejector airbag 36 to expand and eject. An L-shaped isolation plate 352 is located on the right side inside the first gas chamber 35, isolating a space for placing limestone. Ventilation holes 353 are evenly distributed on the surface of the L-shaped isolation plate 352, and limestone is placed in the space formed between the L-shaped isolation plate 352 and the first gas chamber 35. When the temperature inside the first gas chamber 35 rises, some of the limestone decomposes into carbon dioxide. This reaction is exothermic and is used to replenish the carbon dioxide gas consumed in the circulation, ensuring that the ejector airbag can fully expand and eject the pusher plate 51.

[0033] Furthermore, such as Figure 4As shown, the front end of the first gas chamber 35 is provided with two ejector air bladders 36. The carbon dioxide gas in the first gas chamber 35 increases in volume due to heating, and the limestone reacts with the limestone to produce carbon dioxide gas, further increasing the volume of carbon dioxide gas in the ejector air bladders 36. This causes the expansion and contraction corrugations 362 on the ejector air bladders 36 to expand, increasing the length of the ejector air bladders 36, thereby pushing the pusher plate 51 forward. A connecting pipe 361 is provided between the ejector air bladders 36 to ensure a balanced gas distribution between the two ejector air bladders 36, allowing the pusher plate 51 to be pushed out smoothly. Furthermore, the expansion and contraction corrugations 362 are evenly distributed on the surface of the ejector air bladders 36, increasing the expansion degree of the ejector air bladders 36 and enhancing their stability. The extended length reduces the possibility of damage to the ejector airbag 36, ensuring a good clamping effect for the automatic pressure plate structure 5. The left end of the ejector airbag 36 is connected to an air outlet pipe 37. An air extraction device 38 is located at the end of the air outlet pipe 37 furthest from the ejector airbag 36. This device is connected to a second gas chamber 39. The air extraction device 38 is controlled by the control computer 12, causing carbon dioxide gas inside the ejector airbag 36 to enter the second gas chamber 39 through the air outlet pipe 37. This reduces the amount of gas inside the ejector airbag 36, allowing the expansion and contraction corrugations 262 to recover, thus shortening the length of the ejector airbag 36. This resets the push plate 51, releasing the clamping device 52 from the pressure on the bubble film.

[0034] Furthermore, such as Figure 6 As shown, the second gas chamber 39 has an outlet 391 at its left end. The second gas chamber 39 serves to balance the gas balance between the first gas chamber 35 and the ejector airbag 36, acting as a transfer station. Excess carbon dioxide gas in the second gas chamber 39 is discharged through the outlet 391, ensuring that there is no excessive gas in the first gas chamber 35 and the ejector airbag 36, which could lead to an explosion. The second gas chamber 39 has a return pipe 392 at its rear end. The end of the return pipe 392 away from the second gas chamber 39 is equipped with a second suction device 310. The right end of the second suction device 310 is connected to the first gas chamber 35. Both the outlet pipe 37 and the return pipe 392 are equipped with venting valves. When the heating device 34 is working, the venting valves are closed, allowing the carbon dioxide gas in the first gas chamber 35 to flow as far as possible towards the ejector airbag 36, ensuring that the push plate 51 is pushed out, and enabling the pressing device 52 to automatically press the bubble film at the broken film.

[0035] Furthermore, such as Figure 4As shown, the automatic pressing plate structure 5 includes a push plate 51 for connecting the ejector airbag 36 and the pressing device 52, so that the expansion of the ejector airbag 36 can cause the pressing device 52 to be ejected, thereby achieving precise film pressing. The rear end of the push plate 51 is fixedly connected to the ejector airbag 36, and the front end of the push plate 51 is provided with two pressing devices 52, including a straight rod and a pressing plate, which play the role of pressing the broken position of the bubble film. The middle part of the pressing device 52 is adapted to provide a limiting plate 53 to limit the forward ejection distance of the pressing device 52.

[0036] Furthermore, such as Figure 1 As shown, the right end of the lifting column 1 is provided with an automatic slide rail 11, and the rear end of the lifting column 1 is provided with a control computer 12. The control computer 12 is the control center of the entire wrapping machine and controls the operation of the entire wrapping machine. The automatic slide rail 11 is fitted with a wrapping film frame 13. The wrapping film frame 13 is controlled by the control computer 12 and moves up and down along the automatic slide rail 11 to wrap the stacked goods on the conveyor roller structure 8 with bubble wrap.

[0037] Furthermore, the lifting column 1 is equipped with a rotating disk 7 at its front end. The rotating disk 7 rotates at a uniform speed under the control of the control computer 12, so that the stacked goods can be wrapped evenly. The upper end of the rotating disk 7 is equipped with a conveying roller structure 8, which is controlled by the control computer 12 to perform the conveying work, and transfers the wrapped stacked goods to the roller conveyor belt 9. The left and right sides of the rotating disk 7 are symmetrically equipped with roller conveyor belts 9, realizing automatic loading and unloading of stacked goods without the need for a forklift to handle them, thus speeding up the handling process.

[0038] Working process: First, the stacked goods on the right-side roller conveyor belt 9 are transferred to the conveyor roller structure 8. When the stacked goods are centered on the conveyor roller structure 8, the control computer 12 controls the conveyor roller structure 8 to stop working and controls the rotating disk 7 to rotate. The wrapping film frame 13 moves up and down to wrap the stacked goods. Further, after the wrapping is in place, the rotating disk 7 stops working under the control of the control computer 12 and controls the heating device 34 to work. On the one hand, this causes the heating wire 33 to heat up and automatically cut the film; on the other hand, it transfers heat to the first gas chamber 35, causing the temperature inside the first gas chamber 35 to rise. The carbon dioxide gas in the first gas chamber 35 expands due to heat, causing the limestone in the first gas chamber 35 to decompose and produce carbon dioxide gas. The volume of the carbon dioxide gas increases due to heat, causing the ejector airbag 36 to fully expand, thereby ejecting the automatic pressure plate structure 5 and pressing the bubble film. Furthermore, under the action of the rail 22, the automatic tape-adhesive mechanism (61) moves closer to the automatic pressure plate structure (5) to automatically apply tape. Furthermore, the control computer 12 controls the transmission roller structure 8 to work, conveying the film-coated stacked goods to the left roller transmission belt 9 to achieve automatic unloading.
