Description

TECHNICAL FIELD

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

[0002] The bubble film bag is mainly used for product mailing packaging, and can prevent extrusion, vibration and friction of the product during delivery, and has a certain protective effect on the product that is afraid of extrusion and compression. With the increasing demand for online shopping, the production of bubble film bags for the express industry is increasing. In the production process of the bubble film bag, plastic particles are first added to the bubble film machine to produce bubble film, and the produced bubble film is wound into a roll state. Then, the roll state bubble film is transported to the bubble film bag production equipment, the roll state bubble film is installed on the bubble film bag production equipment, and the bubble film is pulled out for the production of the bubble film bag. In this process, there is waste of storage and transportation, which not only makes the production cycle long, but also requires manual transportation and installation of the bubble film. Therefore, the production is wasted. If the bubble film production equipment and the bubble film bag production equipment are connected to form a same production line, the process of winding the bubble film into a roll, installing the roll state bubble film on the equipment and transporting the bubble film can be cut off, the production cycle of the whole production line can be reduced, and the workload of the operator can be reduced. This plays a very important role in the production of the bubble film bag.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN212737413U, patent name: bubble film production equipment) is that the equipment body includes a production box, supporting feet, a material receiving roller and a material feeding roller. The material feeding roller includes a base film feeding roller and a bubble film feeding roller. The production box is provided with a feeding box one, a feeding box two and a material receiving box one. The feeding box one is located below the feeding box two. The base film feeding roller and the bubble film feeding roller are respectively located inside the feeding box one and the feeding box two. The production box is provided with a heating roller, a transfer roller, a temperature sensor, a bubble roller, a glue roller, a fan, cooling ice blocks and a material discharging roller. The material receiving roller is located inside the material receiving box one. The supporting feet are provided with a storage rack in the middle part. The storage rack is provided with an air compressor in the upper part. The supporting feet are provided with a roller in the lower part. The top of the production box is provided with a control panel. The control panel includes a display and a control switch. The side of the production box is provided with a storage rack.

[0004] As can be seen from the above implementation plan, the bubble wrap production equipment is only used to produce bubble wrap. If the bubble wrap needs to be made into bubble wrap bags, the produced bubble wrap needs to be transported between two or more pieces of equipment. Before transporting, the bubble wrap also needs to be rolled up. Rolling and transporting the bubble wrap will take up most of the producer's time, thus affecting the production efficiency of the production workshop. Summary of the Invention

The second buffer component stretches the bubble wrap, reserving the length for the heat pressing and cutting component to stretch the bubble wrap.

[0048] C. The folding component folds the bubble wrap in half along its length.

[0049] D. The pressing part presses the folded bubble wrap in sections through the folding assembly, so that the two layers of bubble wrap stick together due to heat. The cutting part cuts the middle position of the sticking point of the two layers of bubble wrap, so that the bubble wrap forms a single bubble bag.

[0050] Compared with existing technologies, the beneficial effects of the invention are:

[0051] 1. By linking the bubble wrap production unit with the folding unit and the heat pressing and cutting unit, the bubble wrap produced by the bubble wrap production unit can be directly fed into the folding unit and the heat pressing and cutting unit for the production of bubble wrap bags. This saves the steps of rolling the bubble wrap into rolls and installing the rolls of bubble wrap onto the bubble wrap bag production equipment, greatly improving the production efficiency of bubble wrap bags and saving human resources in the production workshop.

[0052] 2. A first buffer component and a second buffer component are set up. When the first buffer component detects that the bubble wrap is stretched, the heat pressing and cutting component will stop operating, and the second buffer component will relax the bubble wrap belt to allow for the length of the heat pressing and cutting component to pull the bubble wrap. Therefore, the bubble wrap production process can be smoothly connected with the bubble wrap bag production process. Attached Figure Description

Detailed Implementation

[0073] The preferred embodiments of the invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the invention.

[0074] like Figures 1 to 18As shown, a bubble wrap bag production line includes a bubble wrap production assembly 1, a first buffer assembly 2, a second buffer assembly 3, a pre-folding transition assembly 4, a folding assembly 5, and a heat-pressing and cutting assembly 6 connected in sequence. The bubble wrap production assembly 1 is used to produce a sheet of bubble wrap from plastic granules. When the first buffer assembly 2 detects that the bubble wrap is stretched, the heat-pressing and cutting assembly 6 stops operating, and the second buffer assembly 3 relaxes the bubble wrap, reserving the length for the heat-pressing and cutting assembly 6 to pull the bubble wrap. Therefore, the bubble wrap production process can be smoothly connected to the bubble wrap bag production process. The folding assembly 5 is used to fold the sheet of bubble wrap along its length, and the heat-pressing and cutting assembly 6 folds the folded bubble wrap. Bubble wrap is pressed at regular intervals along its width, forming individual bag openings from the folded bubble wrap. Then, the second cutter 6063 of the pressing and cutting component 6 cuts the pressed bubble wrap along the indentation, forming bubble wrap bags. This production line links the bubble wrap production component 1 with the folding component 5 and the pressing and cutting component 6. The bubble wrap produced by the bubble wrap production component 1 can be directly fed into the folding component 5 and the pressing and cutting component 6 for bubble wrap bag production, saving the steps of rolling the bubble wrap into rolls and installing the rolls onto the bubble wrap bag production equipment. This greatly improves the production efficiency of bubble wrap bags and saves manpower in the production workshop.

[0075] The bubble wrap production assembly 1 includes a bubble forming component 101, which includes a bubble roller 1011. The bubble roller 1011 has a water passage hole 10111 at its center and several air passage holes 10112 on its circumference. A membrane hole 10113 is provided on the curved surface of the bubble roller 10111, and a suction hole 10114 is provided on the bottom surface of the membrane hole 10113, communicating with the air passage holes 10112. A first cooling component 103 is provided on one side of the bubble roller 1011. The first cooling component 103 includes a tangent first cooling hollow roller 1031 and a second cooling hollow roller 1032, with the first cooling hollow roller 1031 located between the bubble roller 1011 and the second cooling hollow roller 1032. The first cooling hollow roller 1031 and the bubble roller 1011... An extrusion head 109 is located at the top center, and the extrusion head 109 has two elongated extrusion nozzles. After the plastic granules are melted, they are extruded from the extrusion head 109 as two sheet-like, incompletely solidified thin sheets. The two plastic sheets then pass between the first cooling hollow roller 1031 and the bubble roller 1011. At this time, the plastic sheet closer to the bubble roller 1011 is sucked in by a row of membrane holes 10113 of the bubble roller 1011, while the other plastic sheet contacts the first cooling hollow roller 1031. Water flows through the first cooling hollow roller 1031 and the bubble roller 1011, so they can be cooled quickly. After one of the plastic sheets is sucked out of the bubble by the membrane hole 10113, the two plastic sheets quickly stick together. Therefore, the air is trapped inside the bulging bubble, thus forming a bubble film.

[0076] The bubble roller 1011 is connected to the first bearing 1014 and the first water pipe 1016 at both ends. The first water pipe 1016 is equipped with a water pipe bearing 10161. Therefore, when the bubble roller 1011 rotates, the first water pipe 1016 will not rotate with it, ensuring the stability of the connection between the two.

[0077] One end of the bubble roller 1011 is rotatably connected to an adjusting gear plate 1012. The adjusting gear plate 1012 is provided with an air inlet 10122, which is connected to the first air pipe 1015. A gear segment 10121 is provided on the outer periphery of the adjusting gear plate 1012. Angle adjusting shaft 1021 is connected to angle adjusting gear 1022, and angle adjusting gear 1022 is meshed with gear segment 10121. When the bubble roller 1011 rotates, only the row of film holes 10113 that align with the air vents 10112 and air inlets 10122 of the bubble roller 1011 have an adsorption force on the plastic film. The position of the air inlets 10122 on the adjusting gear plate 1012 is determined by rotating the angle adjustment gear 1022. The position of the air inlets 10122 can be adjusted to determine the position of the row of film holes 10113 that can adsorb the plastic film when the bubble roller 1011 rotates. Because different plastic films have different compositions, the time difference between bubble formation and bonding of two bubble films is different. By adjusting the position of bubble formation, the time interval between the two bubble films bonding after bubble formation can be adjusted, thereby ensuring that the two plastic films in each type of bubble film can be firmly bonded together.

[0078] An angle adjustment component 102 is provided on the side of the bubble roller 1011 away from the first cooling component 103. The angle adjustment component 102 includes an angle adjustment seat 1023, which has a plurality of angle positioning holes 10231 arranged in a ring. An angle adjustment shaft 1021 is rotatably connected to the angle adjustment seat 1023. An adjustment disc 10211 is provided at one end of the angle adjustment shaft 1021, and an angle positioning pin 1024 is movably inserted into the adjustment disc 10211. The positioning pin 1024 is rotatably connected to a handle outer ring 1025. The angle positioning pin 1024 is provided with a first retaining ring 10241 and a second retaining ring 10242. The handle outer ring 1025 is located between the first retaining ring 10241 and the adjusting disc 10211, and the second retaining ring 10242 is located between the adjusting disc 10211 and the angle adjusting seat 1023. Rotating the angle adjusting shaft 1021 causes the angle adjusting gear 1022 to rotate, thereby rotating the adjusting gear plate 1012. After determining the position of the adjusting gear plate 1012, the angle adjusting gear 1022 needs to be fixed so that it no longer rotates. Therefore, when rotating the angle adjusting gear 1022, pull the angle positioning pin 1024 away from the angle adjusting gear 1022 so that the angle positioning pin 1024 is not inserted into the angle positioning hole 10231. Then, grasp the outer ring of the handle 1025 so that the adjusting plate 10211 moves with the movement of the outer ring of the handle 1025 to determine the position of the adjusting gear. 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 1023, so that the angle adjustment gear 1022 no longer rotates. The first retaining ring 10241 can prevent the outer ring 1025 of the grip from coming out of the angle positioning pin 1024. 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 coming out of the adjustment plate 10211.

[0079] The bubble wrap production assembly 1 includes a frame 108, and a viewing platform 1081 is provided on one side of the frame 108. When it is necessary to observe the status of bubble wrap production or to perform maintenance on the equipment, the operator can stand on the viewing platform 1081 to observe and perform maintenance.

[0080] Both the bubble forming component 101 and the first cooling component 103 are mounted on the frame 108. A second cooling component 104 is also mounted on the side of the bubble forming component 101 away from the first cooling component 103. A cutting component 105 is mounted on the other side of the second cooling component 104, and a tensioning pre-tightening component 106 is mounted on the other side of the cutting component 105. Grandstand extension rollers 107 are mounted on both sides of the grandstand 1081. Both ends of the first cooling hollow roller 1031 and the second cooling hollow roller 1032 are connected to second bearings 1034, and one end of each roller is connected to a second sprocket 1033 and a second water pipe 1035. Because the plastic granules melt at high temperatures... The plastic sheet is not fully cured, so its temperature is still very high when it is extruded by the extruder head 109. Therefore, the temperature of the plastic sheet is quickly transferred to the bubble roller 1011 and the first cooling hollow roller 1031 that are in contact with it. The second cooling hollow roller 1032 rolls tangentially with the first cooling hollow roller 1031 to help the first cooling hollow roller 1031 remove heat. The bubble roller 1011, the first cooling hollow roller 1031, and the second cooling hollow roller 1032 all remove heat by passing water through them. This not only removes the heat of the bubble film and makes it set quickly, but also reduces the temperature of the bubble roller 1011 and the first cooling hollow roller 1031, preventing them from expanding and contracting due to heat and affecting the forming thickness of the bubble film.

[0081] The cutting component 105 includes a cutting adjustment rod 1051, on which a first cutter 1052 is movably connected. The position of the first cutter 1052 on the cutting adjustment rod 1051 is adjustable. In this embodiment, two first cutters 1052 are provided. The distance between the two first cutters 1052 is adjusted according to the width of the bubble film to be formed, and the two sides of the bubble film are cut off. The middle part continues to be conveyed to the next process. The two cut-off sides are conveyed to the crusher. After being crushed by the crusher, they are conveyed again to the plastic granule melting furnace for recycling.

[0082] The tensioning pre-tightening component 106 includes a pre-tightening slide 1061, a first pre-tightening roller 1062 rotatably connected to the pre-tightening slide 1061, a sprocket connected to the first pre-tightening roller 1062, a pre-tightening slider 1063 slidably connected to the pre-tightening slide 1061, and a second pre-tightening roller 1064 rotatably connected to the pre-tightening slider 1063. A pre-tightening cylinder 1065 is provided at one end of the pre-tightening slide 1061, and the output end of the pre-tightening cylinder 1065 is connected to the pre-tightening slider 1063. The pre-tightening cylinder 1065 is initially in a contracted state. After the bubble wrap is wound along each axis on the equipment, the push rod of the pre-tightening cylinder 1065 is pushed out. At this time, the second pre-tightening roller 1064 pushes the bubble wrap against the first pre-tightening roller 1062, so that the originally loose bubble wrap is tightened, which is more conducive to the transmission of bubble wrap on the production line.

[0083] The upper ends of the first buffer assembly 2 are respectively provided with a first upper roller 201 and a second upper roller 202. A tension pre-tightening component 106 is provided on one side of the first upper roller 201. A buffer sensing component 203 is provided between the tension pre-tightening component 106 and the second upper roller 202. The buffer sensing component 203 includes a lifting sensing seat 2031. A lifting sensor is provided at the upper end of the lifting sensing seat 2031. In this embodiment, the lifting sensor is a proximity sensor. The lifting sensing seat 2031 is slidably connected to a lifting slider 2032, and the lifting slider 2032 is connected to a lifting roller 2033. When the second pre-tightening roller 1064 located in the first buffer assembly 2 presses the bubble film against the first pre-tightening roller 1062, the first pre-tightening roller 1062 rotates and conveys the bubble film to the tension pre-tightening component 106 and the buffer sensing component. Between steps 203 and 204, when the production speed of the bubble wrap bag is slower than the production speed of the bubble wrap, the bubble wrap accumulates on the stretching pretensioning component 106 and the buffer sensing component 203. When the production speed of the bubble wrap bag is equal to the production speed of the bubble wrap, the lifting roller 2033 repeatedly rises and falls in the lifting sensing seat 2031. When the lifting roller 2033 does not reach the top of the lifting sensing seat 2031, the lifting sensor is triggered. When the production speed of the bubble wrap bag is faster than the production speed of the bubble wrap, the lifting roller 2033 will reach the top of the lifting sensing seat 2031 because the bubble wrap is stretched. When the lifting roller 2033 stays on the top of the lifting sensing seat 2031 for more than a set time, the lifting sensor is triggered, thereby pausing the production of the bubble wrap bag and preventing the bubble wrap from breaking.

[0084] The upper part of the second buffer assembly 3 is sequentially provided with a front transition roller group 301, a tension pre-tightening component 106, an upper pull roller 303, and a tail transition roller 304; a lower swing transition roller group 302 is provided below the upper pull roller 303; the front transition roller group 301 includes a lower pull roller body 3011, a first transition roller 3012, and a second transition roller 3013, the installation height of the lower pull roller body 3011 being lower than that of the first transition roller 3012 and the second transition roller 3013; the lower swing transition roller group 302 includes a main swing rod body 3021, with side rod bodies 3022 rotatably connected to both ends of the main swing rod body 3021, and several lower swing rollers 3023 rotatably connected along the longitudinal direction of the side rod bodies 3022, such as Figure 8As shown, after passing through the first transition roller 3012 and the second transition roller 3013, the bubble film is held by the tensioning pre-tensioning component 106 and conveyed towards the tail transition roller 304. Before reaching the tail transition roller 304, the bubble film first passes downwards under one of the lower swing rollers 3023, then upwards over one of the upper pull rollers 303, then downwards under the second lower swing roller 3023, then upwards over the next upper pull roller 303, and so on, until the bubble film passes through all the upper pull rollers 303 and lower swing rollers 3023. Due to the gravity of the lower swing rollers 3023, the bubble film is pulled downwards at this point. Since the other end of the bubble wrap extends to the next process via the tail transition roller 304, when the next process pulls the bubble wrap forward, the bubble wrap pulls up the lower swing roller 3023, and the side rod 3022 swings upward around the main swing rod 3021. When the tensioning pre-tightening component 106 continues to transport the bubble wrap from the first buffer component 2, the side rod 3022 swings downward around the main swing rod 3021. Therefore, the second buffer component 3 plays a buffering role for the bubble wrap during the production process, preventing the pressing and cutting component 6 from pulling the bubble wrap too much and triggering the lifting sensor of the first buffer component 2, thus causing the machine to stop.

[0085] The folding assembly 5 includes a folding platform 513, one end of which is hinged to a folding support plate 501. A lifting pole 502 is installed below the folding support plate 501. The upper end of the pre-folding transition assembly 4 is a downward sloping surface, and the upper end of the folding support plate 501 is lower than the lower end of the sloping surface of the pre-folding transition assembly 4. The folding support plate 501 mainly supports the bubble wrap coming down from the pre-folding transition assembly 4, so as to prevent the weight of the bubble wrap from being unsupported and affecting the subsequent folding process.

[0086] Both the folding receiving plate 501 and the folding platform 513 are equipped with limit adjustment components 503. The limit adjustment component 503 on the folding receiving plate 501 is connected to the correction movable pressure roller 510, and the limit adjustment component 503 on the folding platform 513 is connected to the crease pressure roller 511 and the lower edge pressure roller 512. The folding platform 513 is also equipped with a folding diagonal rod 505. One end of the folding diagonal rod 505 is hinged to the limit adjustment component 503 on the folding platform 513, and the other end of the folding diagonal rod 505 is equipped with a diagonal rod movement detector 508; Figure 10As shown, when the bubble wrap is conveyed to the folding platform 513, one side of the bubble wrap in the width direction begins to fold to the other side. The bubble wrap is input below the folding rod 505 in a folded manner. The folding rod 505 plays a transitional role in the folding process of the bubble wrap. Because at the heat pressing and cutting assembly 6, the bubble wrap is pulled forward a certain distance and then stops for heat pressing. Therefore, when the bubble wrap is pulled, the folding rod 505 shakes up and down due to the push of the bubble wrap. At this time, the rod movement detector 508 detects the movement of the folding rod 505 and can record the signal that the bubble wrap has been pushed forward a certain distance.

[0087] During the folding and movement of the bubble wrap, the crease roller 511 abuts against the folded edge of the bubble wrap. The crease roller 511 includes a first adjusting roller seat 5110, to which the crease roller 5111 is movably inserted. The first adjusting roller seat 5110 is threadedly connected to a positioning bolt handle 5112. Therefore, the distance between the crease roller 5111 and the first adjusting roller seat 5110 is adjustable. The folding line is where the end of the crease roller 5111 abuts against the bubble wrap, and this position can be adjusted to adjust the folded edge of the bubble wrap. The lower edge roller 512 flattens the unfolded lower edge of the bubble wrap, preventing the bottom layer from curling up during folding and affecting the folding accuracy.

[0088] A folding line position detector 507 is installed on the side of the folding platform 513 away from the inclined rod motion detector 508. The outer side of the bubble wrap fold line is close to the folding line position detector 507 during movement. If the folding line position detector 507 does not detect the bubble wrap, it indicates that the bubble wrap has deviated from its intended path during movement, and correction is required. A bottom edge detector 506 is also installed on the folding platform 513, and a side limiting seat 504 is located below the bottom edge detector 506. The bottom edge detector 506 includes a detection base 5061, an X-axis seat 5062 connected to the detection base 5061, a detection moving seat 5063 connected to the X-axis seat 5062, a Y-axis seat 5064 connected to the detection moving seat 5063, and a Z-axis seat 5065 connected to the detection moving seat 5063. The Z-axis seat 5065 connects to the first detector 5066. The position of the first detector 5066 can be adjusted in six directions: up, down, forward, backward, left, and right, to adapt to the detection requirements when forming bubble wrap bags of different sizes. In this embodiment, both the fold line position detector 507 and the first detector 5066 are infrared sensors. The side limiting seat 504 is provided with a detection hole 5041, which is located directly below the first detector 5066. The side limiting seat 504 abuts against the edge of the bottom layer of the bubble wrap to prevent it from deviating from the movement trajectory. The bottom edge detector 506 detects whether the edge of the bottom layer of the bubble wrap moves within a set range through the detection hole 5041. By monitoring the edge of the bottom layer of the bubble wrap and the position of the fold line of the bubble wrap, the accuracy of the bubble wrap fold is detected.

[0089] A pressure roller 509 is provided at the end of the folding platform 513 away from the folding receiving plate 501. The pressure roller 509 can prevent the folded bubble wrap from drifting upwards and affecting the initial folding accuracy.

[0090] The limiting adjustment component 503 includes a limiting base 5031, on which two or more limiting crossbars 5032 are arranged in parallel. The limiting crossbars 5032 are slidably connected to a first moving plate 5033 and a second moving plate 5034. The limiting base 5031 is rotatably connected to a first adjusting screw 5035 and a second adjusting screw 5036, both of which are connected to a screw adjusting handle 5037. The first adjusting screw 5035 is threadedly connected to the first moving plate 5033 and rotatably connected to the second moving plate 5034; therefore, the first adjusting screw 5035 is used to adjust the position of the first moving plate 5033. The second adjusting screw 5036 is threadedly connected to the second moving plate 5034 and rotatably connected to the first moving plate 5033; the second adjusting screw 5036 is used to adjust the threaded position of the second moving plate 5034.

[0091] In this embodiment, two corrective movable pressure rollers 510 are provided. Each corrective movable pressure roller 510 includes a movable pressure roller seat 5101, which is connected to a pressure roller drive cylinder 5102. The output end of the pressure roller drive cylinder 5102 is rotatably connected to a pressure roller 5103. During the movement of the bubble film, it is inevitable that it will deviate slightly. When the fold line position detector 507 detects that the bubble film is moving towards the side limit seat 504, the pressure roller 5103 on the side closer to the fold line position detector 507 presses down on the bubble film. At this time, the movement of the pressed bubble film slows down, while the movement of other points increases. Since the pressure remains constant, the front end of the pressed area exhibits an arching phenomenon of the bubble film. When the pressure roller 5103 is lifted upwards, the arching is released, causing the bubble film at that point to move faster. The bubble film, which was originally deviated from the fold line position detector 507, now moves more towards the fold line position detector 507. When the first detector 5066 detects that the bubble film is moving away from the side limit seat 504, the pressure roller 5103 on the side closer to the side limit seat 504 presses down on the bubble film, correcting the bubble film using the same principle as described above, so that the bubble film can remain in the middle position during its movement.

[0092] The heat-pressing and cutting assembly 6 includes a heat-pressing drive unit 601, a heat-pressing unit 605, and a cutting unit 606. The heat-pressing unit 605 and the cutting unit 606 are driven by the same motor. In this embodiment, six heat-pressing units 605 are provided. Therefore, when the bubble wrap is folded into a bubble bag, the edge of the bubble bag will be heat-pressed a total of six times. Through multiple heat-pressing, it is ensured that the two layers of bubble wrap can be firmly bonded together after heat-pressing. Because it is multiple heat-pressing, the time occupied by each heat-pressing can be reduced, which further improves the production efficiency of the production line.

[0093] The heat-pressing and cutting assembly 6 includes a rack 603 and a slide rail 604 arranged in parallel, and a plurality of heat-pressing parts 605 are disposed on the rack 603 and the slide rail 604; both ends of the heat-pressing and cutting assembly 6 are provided with heat-pressing driving parts 601, and heat-pressing limiting parts 602 are provided between the heat-pressing driving parts 601 and the heat-pressing parts 605; the heat-pressing part 605 includes a heat-pressing base 6051, the heat-pressing base 6051 is connected to a position adjusting rod 6052, and the position adjusting rod 6052 is connected to a position adjusting rack. The wheel 60521, the position adjustment gear 60521 and the rack 603 are meshed and connected. One end of the position adjustment rod 6052 is connected to the position adjustment handle 60522. By rotating the position adjustment handle 60522, the position adjustment gear 60521 and the rack 603 are meshed, thereby causing the pressing part 605 to move in the direction of the rack 603. The width of the final formed bubble wrap bag is set by setting the distance between every two pressing parts 605 and the speed of the bubble wrap movement.

[0094] A heat-pressing base 6051 is provided with a heat-pressing lower pad 60512. Upper product limit rods 60511 are provided on both sides of the heat-pressing lower pad 60512. A heat-pressing movable plate 6054 is provided above the heat-pressing base 6051. An upper spring 6056 is connected to the upper part of the heat-pressing movable plate 6054, and a lower spring 6057 is connected to the lower part. The upper spring 6056 and the lower spring 6057 are coaxially arranged. A heat-pressing sliding shaft 6055 is inserted into the center of the upper spring 6056 and the lower connecting spring 6057. The heat-pressing sliding shaft 6055 is movably inserted into the heat-pressing movable plate 6054 and the heat-pressing base 6051. A sliding upper baffle 60552 is provided at the upper end of the heat-pressing sliding shaft 6055. The lower end of the sliding shaft 6055 is rotatably connected to the heat-pressing roller 60551. The upper spring 6056 is located between the upper sliding baffle 60552 and the heat-pressing movable plate 6054. The lower spring 6057 is located between the heat-pressing movable plate 6054 and the heat-pressing base 6051. A compression block is also fixed to the heat-pressing sliding shaft 6055. The compression block is located below the heat-pressing base 6051. The distance between the compression block and the upper sliding baffle 60552 is less than the sum of the lengths of the upper spring 6056 and the lower spring 6057 in their natural state. The compression force of the upper spring 6056 is greater than the compression force of the lower spring 6057. Therefore, the heat-pressing plate 6058 is always in a downward pressing state.

[0095] The pressing plate 6054 is connected to several pressing plate leveling bolts 6059, and the lower end of the pressing plate leveling bolts 6059 is connected to the pressing plate 6058. The pressing plate leveling bolts 6059 can be used to adjust the pressing plate 6058 and the pressing pad 60512 to be parallel, so that when the pressing plate 6058 is pressed down, the lower surface of the pressing plate 6058 is in contact with the upper surface of the pressing pad 60512.

[0096] A pressing and lifting power unit 6053 is provided below the pressing base 6051. The pressing and lifting power unit 6053 includes a pressing and lifting drive shaft 60531, which is connected to a pressing and lifting drive sprocket 60532. The two ends of the pressing and lifting drive shaft 60531 are connected to a first eccentric wheel 60533, which is tangent to the pressing lower roller 60551. When the first eccentric wheel 60533 rotates, it lifts the pressing sliding shaft 6055, and the pressing plate 6058 is raised. At this time, the bubble wrap is pulled. Then the first eccentric wheel 60533 continues to rotate, and the pressing plate 6058 presses down the two layers of the bubble wrap, which are pressed together.

[0097] The slicing section 606 includes a slicing base 6061, a lower guide rod 60611 fixedly connected to the lower end of the slicing base 6061, a cutter mounting plate 6062 slidably connected above the slicing base 6061, a second cutter 6063 and a slicing sliding shaft 6064 connected below the cutter mounting plate 6062, the slicing sliding shaft 6064 slidably inserted into the slicing base 6061, and a slicing lifting plate 6066 connected to the lower end of the slicing sliding shaft 6064. A cutting spring 6065 is provided between the cutting base 6061 and the cutting lifting plate 6066, and a cutting drive shaft 6067 is also provided between the cutting base 6061 and the cutting lifting plate 6066. The cutting drive shaft 6067 is connected to a cutting drive sprocket 60671, and second eccentric wheels 60672 are connected to both ends of the cutting drive shaft 6067. The second eccentric wheels 60672 are tangential to the cutting lifting plate 6066, and the cutting base 6061 is fixed. Without moving, the second eccentric wheel 60672 rotates, pushing the cutting lifting plate 6066 to move up and down. The cutting lifting plate 6066 is connected to the cutting sliding shaft 6064, thereby driving the second cutter 6063 to move up and down to cut the bubble wrap bag into segments. The cutting spring 6065 connects the cutting lifting plate 6066 and the cutting sliding shaft 6064. When the second eccentric wheel 60672 is not in contact with the cutting lifting plate 6066 at its maximum position, the cutting lifting plate 6066 remains in an upward state due to the action of the cutting spring 6065, so that the second cutter 6063 is in an open state, facilitating the passage of the bubble wrap bag. Since the cutting drive sprocket 60671 and the heat pressing drive sprocket 60532 are both controlled by the same motor, it can be ensured that the side of the bubble wrap bag is being cut on the same line when it is being heat pressed, ensuring the synchronization of the entire process and preventing the bubble wrap bag cutting position from not overlapping with the heat pressing position, resulting in defective products.

[0098] The method for producing bubble wrap bags using a bubble wrap bag production line includes the following steps:

[0099] A. The extrusion head 109 of the bubble film production component 1 extrudes two unsolidified film sheets. The two film sheets pass through the middle of the first cooling hollow roller 1031 and the bubble roller body 1011. One of the film sheets is adsorbed by the membrane hole 10113 of the bubble roller body 1011 to generate a bubble shape. The two film sheets are bonded together to form a bubble film.

[0100] B. After passing through the first buffer component 2, the second buffer component 3, and the pre-folding transition component 4, the bubble wrap reaches the folding component 5. When the first buffer component 2 detects that the bubble wrap is stretched, the heat pressing and cutting component 6 will stop operating. The second buffer component 3 stretches the bubble wrap, reserving the length for the heat pressing and cutting component 6 to stretch the bubble wrap.

[0101] C. Folding component 5 folds the bubble wrap in half along its length.

[0102] D. The pressing part 605 presses the folded bubble wrap through the folding component 5 in sections, so that the two layers of bubble wrap stick together due to heat. The cutting part 606 cuts the middle position of the sticking point of the two layers of bubble wrap, so that the bubble wrap forms a single bubble bag.

[0103] Finally, it should be noted that the above are merely preferred embodiments of the invention and are not intended to limit the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
