Description

Technical Field

[0001] The invention relates to the technical field of bubble film production equipment, in particular to a bubble film bag production line and a method thereof. Background Art

[0002] Bubble film bags are mainly used for mailing packaging of products, especially for items that require shock-resistant cushioning and protection. Bubble film bags can prevent the items from being squeezed, vibrated, and rubbed during delivery, and have a certain protective effect on items that are afraid of squeezing and pressure. As people's demand for online shopping grows, the output of bubble film bags required by the express delivery industry is increasing. In the production process of bubble film bags, plastic particles are first added to the bubble film machine to produce bubble film, and the produced bubble film is rolled into a roll state, and then the rolled bubble film is transported to the bubble film bag production equipment, the rolled bubble film is installed on the bubble film bag production equipment, and then the bubble film is pulled out to produce the bubble film bag. There is a waste of storage and transportation in this process, which not only makes the production cycle long, but also requires manual transportation and installation of the bubble film, thus causing waste in production. If the bubble film production equipment and the bubble film bag production equipment can be connected to form the same production line, the bubble film can be cut into a roll, the rolled bubble film can be installed on the equipment, and the transportation process can be removed, which will reduce the production cycle of the entire production line and reduce the workload of the operators, which will play a very important role in the production of bubble film bags.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention, and are not used to limit the invention.

[0017] like Figures 1 to 18As shown, a bubble film bag production line includes a bubble film production component 1, a first buffer component 2, a second buffer component 3, a transition component 4 before folding, a folding component 5, and a pressing and cutting component 6 which are connected in sequence; the bubble film production component 1 is used to produce a piece of bubble film from plastic particles; when the first buffer component 2 detects that the bubble film is tightened, the pressing and cutting component 6 stops running, and the second buffer component 3 relaxes the bubble film, leaving a length for the pressing and cutting component 6 to pull the bubble film; therefore, the bubble film production process and the bubble film bag production process can be smoothly connected; the folding component 5 is used to fold the sheet of bubble film in half along the length direction of the bubble film, and the pressing and cutting component 6 The bubble film is pressed at regular intervals along the width direction, so that the folded bubble film is pressed into bag openings, and then the cutter 6063 of the pressing and cutting component 6 cuts the pressed bubble film along the indentation to form a bubble film bag. This production line links the bubble film production component 1 with the folding component 5 and the pressing and cutting component 6. The bubble film produced by the bubble film production component 1 can be input into the folding component 5 and the pressing and cutting component 6 to produce the bubble film bag, which saves the process of rolling the bubble film into a roll and installing the rolled bubble film on the bubble film bag production equipment, greatly improves the production efficiency of the bubble film bag, and saves human resources in the production workshop.

[0018] The bubble film production component 1 includes a bubble forming component 101, and the bubble forming component 101 includes a bubble roller body 1011. A water hole 10111 is arranged at the center of the bubble roller body 1011, and a plurality of air holes 10112 are arranged on the circumference of the bubble roller body 1011. A film hole 10113 is arranged on the curved surface of the bubble roller body 1011, and a film absorption hole 10114 is arranged on the bottom surface of the film hole 10113, and the film absorption hole 10114 is communicated with the air hole 10112; a first cooling component 103 is arranged on one side of the bubble roller body 1011, and the first cooling component 103 includes a tangent first cooling hollow roller 1031 and a second cooling hollow roller 1032, and the first cooling hollow roller 1031 is located between the bubble roller body 1011 and the second cooling hollow roller 1032; the first cooling hollow roller 1031 and the bubble roller body 1011 An extrusion head 109 is arranged just above the middle, and the extrusion head 109 is provided with two long extrusion ports; after the plastic particles are melted, they are extruded from the extrusion head 109, and when they are extruded, they are two sheets of uncured thin sheets, and then the two plastic sheets pass through the middle of the first cooling hollow roller 1031 and the bubble roller body 1011, at this time, the plastic sheet close to the side of the bubble roller body 1011 is sucked in by a row of membrane holes 10113 for ventilation of the bubble roller body 1011, and the other plastic sheet contacts the first cooling hollow roller 1031, and the first cooling hollow roller 1031 and the bubble roller body 1011 are both water-permeable, so they can be cooled quickly, and after the bubble of one of the plastic sheets is sucked out by the membrane hole 10113, the two plastic sheets are quickly bonded together, so that the air is wrapped in the bulging bubble, thereby forming a bubble film.

[0019] The two ends of the bubble roller body 1011 are connected to the first seat bearing 1014 and the first water pipe 1016, and a water pipe bearing 10161 is arranged inside the first water pipe 1016; therefore, when the bubble roller body 1011 rotates, the first water pipe 1016 will not rotate with it, thereby ensuring the stability of the connection between the two.

[0020] One end of the bubble roller body 1011 is rotatably connected to an adjusting gear plate 1012, on which an air connection hole 10122 is provided, which is connected to the first air pipe 1015, and a gear segment 10121 is provided on the periphery of the adjusting gear plate 1012; the angle adjustment shaft 1021 is connected to the angle adjustment gear 1022, which is meshingly connected to the gear segment 10121. When the bubble roller body 1011 rotates, only the row of membrane holes 10113 where the air holes 10112 of the bubble roller body 1011 connect with the air holes 10122 have adsorption force on the plastic film, and the adjusting gear plate 1012 is rotated by rotating the angle adjustment gear 1022 to determine the position of the air holes 10122 on the adjusting gear plate 1012. The position of the row of membrane holes 10113 that can adsorb the plastic film when the bubble roller body 1011 rotates can be adjusted by the position of the air holes 10122. Because different plastic films have different compositions, the time difference between bubble forming and bonding of two bubble films is different. By adjusting the position of bubble forming, the time interval between the two bubble films being bonded after bubble forming can be adjusted, thereby ensuring that the two plastic films in each bubble film can be firmly bonded together.

[0021] The bubble roller body 1011 is provided with an angle adjustment component 102 on one side away from the first cooling component 103. The angle adjustment component 102 includes an angle adjustment seat body 1023. The angle adjustment seat body 1023 is provided with a plurality of angle positioning holes 10231 distributed in an annular manner. The angle adjustment seat body 1023 is rotatably connected with an angle adjustment shaft body 1021. An adjustment disk 10211 is provided at one end of the angle adjustment shaft body 1021. The adjustment disk 10211 is movably plugged with an angle positioning pin 1024. The positioning pin 1024 is rotatably connected to the handshake outer ring 1025. The angle positioning pin 1024 is provided with a first retaining ring 10241 and a second retaining ring 10242. The handshake outer ring 1025 is located between the first retaining ring 10241 and the adjustment disk 10211, and the second retaining ring 10242 is located between the adjustment disk 10211 and the angle adjustment seat 1023. The angle adjustment gear 1022 is rotated by rotating the angle adjustment shaft 1021, thereby rotating the adjustment gear plate 1012. After determining the position of the adjustment gear plate 1012, the angle adjustment gear 1022 needs to be fixed so that it no longer rotates. Therefore, when rotating the angle adjustment gear 1022, the angle positioning pin 1024 is pulled out in a direction away from the angle adjustment gear 1022 so that the angle positioning pin 1024 is not inserted into the angle positioning hole 10231. Then, the handshake outer ring 1025 is grasped so that the adjustment disk 10211 moves along with the movement of the handshake outer ring 1025. After the wheel plate 1012 is positioned, the angle positioning pin 1024 is inserted into the corresponding angle positioning hole 10231 of the angle adjustment seat body 1023, so that the angle adjustment gear 1022 no longer rotates, and the first retaining ring 10241 can prevent the handshake outer ring 1025 from escaping from the angle positioning pin 1024, and the second retaining ring 10242 can limit the length of the angle positioning pin 1024 inserted into the angle positioning hole 10231, and can also limit the angle positioning pin 1024 from escaping from the adjustment disk 10211.

Therefore, the temperature of the plastic sheet will be quickly transferred to the bubble roller body 1011 and the first cooling hollow roller 1031 in contact with it, and the second cooling hollow roller 1032 rolls tangentially with the first cooling hollow roller 1031 to assist the first cooling hollow roller 1031 in taking away heat. The bubble roller body 1011, the first cooling hollow roller 1031 and the second cooling hollow roller 1032 all take away heat by passing water, which can not only take away the heat of the bubble film to quickly shape it, but also reduce the temperature of the bubble roller body 1011 and the first cooling hollow roller 1031 to avoid their thermal expansion and contraction affecting the molding thickness of the bubble film.

[0024] The cutting component 105 includes a cutting adjustment rod 105, on which a cutter 1052 is movably connected; the position of the cutter 1052 on the cutting adjustment rod 105 is adjustable.

The pre-tightening cylinder 1065 is initially in a contracted state. After the bubble film belt is wound around the equipment along each axis, the push rod of the pre-tightening cylinder 1065 is pushed out. At this time, the second pre-tightening roller 1064 pushes the bubble film toward the first pre-tightening roller 1062, so that the originally loose bubble film is tightened, which is more conducive to the transmission of the bubble film on the production line.

[0026] The first upper roller 201 and the second upper roller 202 are respectively provided at the two ends of the upper part of the first buffer component 2, and a stretching pre-tightening component 106 is provided on one side of the first upper roller 201, and a buffering sensing component 203 is provided between the stretching pre-tightening component 106 and the second upper roller 102. The buffering sensing component 203 includes a lifting sensing seat 2031, and a lifting sensor is provided on the upper end of the lifting sensing seat 2031. In this embodiment, the lifting sensor is a proximity sensor, and the lifting sensing seat 2031 is slidably connected with a lifting slider 2032, and the lifting slider 2032 is connected to the lifting roller 2033; when the second pre-tightening roller 1064 located in the first buffer component 2 pushes the bubble film toward the first pre-tightening roller 1062, the first pre-tightening roller 1062 rotates to transport the bubble film to the stretching pre-tightening component 106 and the buffering sensing component 203, when the production speed of the bubble film bag is slower than the production speed of the bubble film, the bubble film is accumulated on the stretching preload component 106 and the buffer sensing component 203, when the production speed of the bubble film bag is equivalent to the production speed of the bubble film, the lifting roller 2033 is repeatedly lifted and lowered in the lifting sensing seat 2031. When the lifting roller 2033 does not reach the top of the lifting sensing seat 2031 and triggers the lifting sensor, when the production speed of the bubble film bag is faster than the production speed of the bubble film, the lifting roller 2033 will reach the top of the lifting sensing seat 2031 because the bubble film is tightened, and when the lifting roller 2033 stays on the top of the lifting sensing seat 2031 for more than the set time, the lifting sensor will be triggered, thereby suspending the production of the bubble film bag to avoid breaking the bubble film.

Before the bubble film reaches the tail transition roller 304, the bubble film first passes downward under one of the lower swing rollers 3023, then passes upward over one of the upper pull rollers 303, then passes downward under the second lower swing roller 3023, then passes upward over the next upper pull roller 303, and so on, until the bubble film passes through all the upper pull rollers 303 and the lower swing rollers 3023. Due to the gravity of several lower swing rollers 3023, the bubble film is in a state of being pulled downward at this point. state, and because the other end of the bubble film extends to the next process through the tail end transition roller 304, when the next process pulls the bubble film forward, the bubble film pulls up the lower swing roller 3023, and the side rod body 3022 swings upward around the main swing rod body 3021. When the stretching pre-tightening component 106 continues to transport the bubble film from the first buffer assembly 2, the side rod body 3022 swings downward around the main swing rod body 3021. Therefore, the second buffer assembly 3 plays a buffering role for the bubble film during the production process, preventing the pressing and cutting assembly 6 from pulling the bubble film too much and touching the lifting sensor of the first buffer assembly 2 to cause shutdown.

The folding diagonal rod 505 plays a transitional role in the folding process of the bubble film, because at the pressing and cutting assembly 6, the bubble film is pulled forward a certain distance and then paused for pressing. Therefore, when the bubble film is pulled, the folding diagonal rod 505 swings up and down due to the push of the bubble film. At this time, the diagonal rod activity detector 508 detects the movement of the folding diagonal rod 505, and can record the signal that the bubble film is pushed a certain distance.

The outer side of the folding line of the bubble film is close to the folding line position detector 507 during the movement. If the folding line position detector 507 cannot detect the bubble film, it means that the bubble film has deviated from the predetermined route during the movement, and the bubble film needs to be corrected.

The degree remains unchanged, so the front end of the pressed part has an arched bubble film phenomenon, and when the pressure wheel 5103 is lifted upward, the arched part is released, and the bubble film at this part moves faster, so the bubble film originally deviated from the folding line position detector 507, but now moves more toward the folding line position detector 507, and when the first detector 5066 detects that the bubble film moves away from the side limit seat 504, the pressure wheel 5103 close to the side limit seat 504 presses down the bubble film, and the bubble film is corrected by the same principle as mentioned above, so that the bubble film can be kept in the middle position during the movement.
