Description

Technical Field

[0001] This invention relates to the field of mattress packaging technology, and more particularly to a folding mattress film-coating packaging device and method. Background Technology

[0002] A folding mattress is a type of mattress with folding function made of filling material. This type of mattress is portable, lightweight, durable, and provides comfortable softness and lasting elasticity, ensuring the user's comfort and health. In order to ensure that the mattress is not contaminated during transportation, a film wrapping process is usually required to wrap the mattress with a film.

[0003] In existing technologies, folding mattresses are often laminated using laminating equipment. To reduce dust and impurities on the mattress surface, it is generally necessary to clean the mattress before lamination. However, before entering the laminating equipment, the cleaned mattress is prone to secondary dust contamination due to the presence of many loose threads and other impurities in the factory, affecting quality. Furthermore, the mattress cannot be uniformly sterilized before lamination, allowing bacteria and mold to multiply rapidly after lamination, impacting the final product quality. Moreover, common laminating equipment does not readily expel air from the film during hot pressing and cannot smooth the film, resulting in poor lamination quality. To address these issues, this invention proposes a laminating and packaging device and method for folding mattresses. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies that commonly use laminating equipment to laminate folding mattresses. In order to reduce dust and impurities on the mattress surface, the mattress usually needs to be cleaned before lamination. However, after cleaning, the mattress is prone to secondary dust contamination due to the presence of many loose threads and other impurities in the factory before entering the laminating equipment, affecting quality. Furthermore, the lack of uniform sterilization before lamination allows bacteria and mold to multiply rapidly inside the mattress after lamination, impacting the quality of the finished product. Additionally, common laminating equipment does not readily expel air from the film during hot pressing and cannot smooth the film, resulting in poor lamination quality. Therefore, this invention proposes a laminating and packaging device and method for folding mattresses.

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

[0006] A folding mattress film-sealing packaging device includes a folding mattress packaging mechanism, wherein a mattress sealing mechanism is mounted on the folding mattress packaging mechanism;

[0014] A roller frame is fixedly connected to the pin shaft. Sliding sleeves are slidably connected to both ends of the roller frame. A roller body is rotatably installed between the two sliding sleeves. A third spring is fixedly connected to one side of the sliding sleeve. One end of the third spring is fixedly connected to the side wall of the roller frame.

[0015] Preferably, the dust removal component includes a dust collection chamber, which is installed on the film-coating packaging equipment. The dust collection chamber is connected to a vacuum cleaner, which is also installed on the film-coating packaging equipment. The vacuum cleaner is connected to a frame-shaped vacuum head, which is fixed at the feed inlet of the film-coating packaging equipment.

[0016] Preferably, the hot air assembly includes a hot air blower, which is fixedly installed above the film-coating packaging equipment. The air inlet of the hot air blower is equipped with a filter, and the hot air blower is connected to a flexible hose that extends downward into the film-coating packaging equipment.

[0017] Preferably, the adjustable heat output component includes four hot air heads, which are arranged to form a frame structure. The four hot air heads are located in the film-coating packaging equipment and are located at the feed inlet of the film-coating packaging equipment. The four hot air heads are connected to the four ends of the hose. The two sides of the lower hot air heads are fixedly connected to a striking frame. The two ends of the hot air heads are respectively fixedly connected to a connecting shaft and a movable frame. One end of the connecting shaft is fixedly connected to a telescopic rod, and the telescopic rod is fixedly connected to the inner wall of the film-coating packaging equipment.

[0018] The movable frame has two slanted openings, and a support shaft is slidably connected to the two slanted openings. The support shaft is mounted on the connecting shaft.

[0019] Preferably, the reciprocating motion component includes a motor, which is fixedly mounted on the bottom wall of the film-coating packaging equipment. The output shaft of the motor is rotatably mounted on a fixed seat via a bearing. The fixed seat is fixedly connected to the bottom wall of the film-coating packaging equipment. A cam is fixedly connected to the output shaft of the motor. A roller rod is attached to one side of the cam. The roller rod slides through a fixed plate. The fixed plate is fixedly connected to the bottom wall of the film-coating packaging equipment. A connecting strip is fixedly connected to one end of the roller rod. The connecting strip is fixedly connected to a hot air head below. A first spring is fixedly connected between the connecting strip and the fixed plate.

[0020] A method of using a folding mattress film-coating packaging device includes the following steps:

[0021] S1. When wrapping the folding mattress, first control the hot air blower to output high-temperature hot air through the hot air head. Then control the motor to drive the cam to rotate. The convex surface of the cam presses the roller rod to move, causing the roller rod to drive the first spring to deform through the connecting bar. When the convex surface of the cam moves away from the roller rod, the first spring drives the connecting bar to return to its original position until the cam presses the roller rod again, causing the cam to work with the first spring to drive the connecting bar to reciprocate. The connecting bar drives the hot air head below to reciprocate. At the same time, the hot air head below drives the tapping frame to reciprocate, causing the movable frames on both sides and the connecting shaft to follow the movement. Then, through the cooperation of the support shaft and the inclined plate, control the remaining hot air heads to reciprocate, so that multiple hot air heads can achieve reciprocating movement.

[0022] S2. Then, the folded mattress is fed into the inlet of the film packaging equipment, and the reciprocating hot air head performs uniform high-temperature sterilization on the folded mattress. At the same time, the folded mattress passes through the beating frame, which beats and vibrates the folded mattress. Meanwhile, the vacuum cleaner runs through the frame-shaped vacuum head to vacuum the dust, which is then collected in the dust collection chamber. After dust removal, the folded mattress is conveyed through the conveying mechanism in the film packaging equipment. During the conveying process, the folded mattress is laminated with a film. When the folded mattress is output from the outlet of the film packaging equipment, the heat sealing structure of the film packaging equipment seals the film.

[0023] S3. After the folding mattress is conveyed onto the conveyor structure, the electric push rod is controlled to move the heat sealing head, causing the support frame to follow the upper heat sealing head downwards. This causes the roller to contact the film outside the folding mattress. At this time, the connecting frame continues to move downwards, loosening the rope. The torque of the torsion spring then drives the rope disc to rotate and wind up the rope. The rope disc also drives the screw to rotate. The two screws drive the two threaded seats to move away from each other, causing the gear to follow and move. The gear meshes with the toothed plate, causing the gear to drive the roller frame to flip. The roller flips and the roller deforms by squeezing the third spring through the sliding sleeve, allowing the roller to flip smoothly to the other side. At this time, the roller continues to roll on the film, causing the film to unfold. When the connecting frame moves downwards, it causes the positioning port and the elastic buckle to squeeze and deform, causing the elastic buckle to contract and deform. The top of the elastic buckle passes through the positioning port and re-engages with the positioning port through deformation. When the upper and lower heat sealing heads move relative to each other, they perform heat sealing operations on the films on both sides.

[0024] S4. After the film is coated, control the electric push rod to retract, so that the heat sealing head is reset. When the movable rod contacts the bracket upward, the movable rod applies force downward to the connecting frame, so that the connecting frame applies force to the elastic buckle, so that the elastic buckle deforms and passes through the positioning hole. At the same time, the rope extends, so that the rope disc rotates and drives the threaded seat to reset through the screw, and then the two rollers flip and reset relative to each other, so as to carry out the next sealing operation.

[0025] Compared with the prior art, the present invention provides a folding mattress film-coating packaging device and method, which has the following beneficial effects:

[0026] 1. The folding mattress laminating and packaging equipment and method utilizes a motor-driven cam to press the roller rod in conjunction with the first spring. This allows the roller rod to rotate the hot air head via a connecting strip. Through the cooperation between the support shaft and the inclined opening, multiple hot air heads work together in a reciprocating motion. The hot air blower outputs hot air through these hot air heads. When the folding mattress enters the laminating and packaging process, the hot air head assembly outputs high temperatures through reciprocating motion, providing uniform high-temperature sterilization. Simultaneously, the folding mattress vibrates through the reciprocating impact of the striking frame, facilitating dust removal. Combined with a dust removal component, this further enhances the dust removal process, thereby improving the finished product quality of the folding mattress.

[0027] 2. The folding mattress laminating and packaging equipment and method utilizes a sealing assembly for the sealing process. The support frame moves downwards, bringing the rollers into contact with the film on the outside of the folding mattress. As the support frame continues to move downwards, the ropes loosen. The torque of the torsion spring then drives the rope disc and screw to rotate, which in turn drives the threaded seats. The two threaded seats move away from each other, causing two gears to move and mesh with the toothed plate, resulting in the two rollers rotating in opposite directions. This allows the rollers to roll and smooth the film from the center. After rotating, the rollers can continue to be pushed forward by the threaded seats, allowing them to roll to the edge of the folding mattress. This unfolds and smooths the wrinkles in the film, improving the quality of the folding mattress lamination. Furthermore, the smoothing process removes air from inside the film, preventing internal expansion from affecting the lamination quality.

[0028] 3. The folding mattress laminating and packaging equipment and method utilizes a hot air assembly in conjunction with an adjustable hot air output assembly to output hot air. Simultaneously, the adjustable hot air output assembly, in conjunction with a reciprocating motion assembly, causes the hot air head to reciprocate, thereby uniformly heating the folding mattress. The mattress is then heated to a higher temperature, and a sealing assembly performs the sealing process. A drive mechanism, in conjunction with a smoothing assembly, forces air out of the film, significantly reducing the amount of air inside. After successful sealing, the residual heat of the folding mattress cools down, and through the principle of thermal expansion and contraction, the film contracts and tightens onto the mattress, thus aiding in a tight lamination and improving the overall lamination effect.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] Example 1: Refer to Figure 1-2 and Figure 9-13A folding mattress laminating and packaging device includes a folding mattress packaging mechanism 100. The folding mattress packaging mechanism 100 includes a base 101. A conveying structure 104 and a laminating and packaging device 102 are fixedly installed above the base 101. The conveying structure 104 can output the laminating folding mattress, thus facilitating the unloading operation. A dust removal component 105 is provided on one side of the laminating and packaging device 102. The dust removal component 105 includes a dust collection chamber 1051, which is installed on the laminating and packaging device 102 and is connected to a vacuum cleaner 1052. The vacuum cleaner 1052 is installed on the laminating and packaging device 102. On the equipment 102, a vacuum cleaner 1052 is connected to a frame-shaped vacuum head 1053. The vacuum cleaner 1052 can perform vacuuming operations through the frame-shaped vacuum head 1053, while the dust flows back into the dust collection chamber 1051 for collection, preventing dust from spreading outward and thus improving the quality of the processing environment. The frame-shaped vacuum head 1053 is fixed at the feed inlet of the film packaging equipment 102. The film packaging equipment 102 is internally equipped with a reciprocating motion component 107 and an adjustable heat output component 106. The adjustable heat output component 106 includes four hot air heads 1066, which form a frame structure. After the components 66 are assembled to form a frame structure, they surround the perimeter of the folding mattress. Four hot air heads 1066 are located within the laminating and packaging equipment 102, positioned at the inlet of the equipment. The four hot air heads 1066 are connected to the four ends of a flexible hose 1032, which transmits heat and moves with the hot air heads 1066, allowing for smooth reciprocating motion. Striking frames 1065 are fixedly connected to both sides of the lower hot air head 1066. A connecting shaft 1067 and a movable frame 1061 are fixedly connected to both ends of the hot air head 1066. One end of the shaft 1067 is fixedly connected to a telescopic rod 1062. The telescopic rod 1062 can ensure the stable extension and retraction of the connecting shaft 1067 and the hot air head 1066. The telescopic rod 1062 is fixedly connected to the inner wall of the film packaging equipment 102. Two oblique openings 1064 are opened on the movable frame 1061. The support shaft 1063 is slidably connected in the two oblique openings 1064. The support shaft 1063 and the oblique openings 1064 perform a squeezing motion, which can link the other hot air heads 1066 to achieve the purpose of reciprocating motion, thereby facilitating the uniform heating of the folding mattress. The support shaft 1063 is installed on the connecting shaft 1067.

[0046] The adjustable heat output component 106 is connected to the reciprocating motion component 107 at its lower part. The reciprocating motion component 107 includes a motor 1071, which is fixedly mounted on the bottom wall of the film-coating packaging equipment 102. The output shaft of the motor 1071 is rotatably mounted on a fixed base 1073 via bearings. The fixed base 1073 is fixedly connected to the bottom wall of the film-coating packaging equipment 102. A cam 1072 is fixedly connected to the output shaft of the motor 1071. The cam 1072 is petal-shaped and has multiple protrusions, allowing the convex surface of the cam 1072 to move smoothly. The roller rod 1074 moves by squeezing, and the roller rod 1074 can reduce the frictional resistance between itself and the cam 1072. The roller rod 1074 overlaps one side of the cam 1072 and slides on the fixed plate 1075. The fixed plate 1075 is fixedly connected to the bottom wall of the film packaging equipment 102. A connecting strip 1077 is fixedly connected to one end of the roller rod 1074. The connecting strip 1077 is fixedly connected to the hot air head 1066 below. A first spring is fixedly connected between the connecting strip 1077 and the fixed plate 1075. 1076. When the convex surface of cam 1072 moves away from roller rod 1074, the resetting force of the first spring 1076 can drive the connecting bar 1077 to reset, thereby resetting the hot air head 1066. When the convex surface of cam 1072 presses the roller rod 1074 again, the hot air head 1066 moves again, thereby causing the first spring 1076 to cooperate with cam 1072 to realize the reciprocating motion of the hot air head 1066. The adjustable heat output component 106 is located at the inlet position of the film packaging equipment 102, and the adjustable heat output component 106 and the... The hot air assembly 103 is connected and includes a hot air blower 1031. The hot air blower 1031 is fixedly installed above the film packaging equipment 102. The air inlet of the hot air blower 1031 is equipped with a filter to filter the incoming air. The hot air blower 1031 can also generate heat, which can be output through the hot air head 1066 to heat the folding mattress at a high temperature, thereby facilitating the high-temperature sterilization of the folding mattress. The hot air blower 1031 is connected to a hose 1032, which extends downward into the film packaging equipment 102.

[0047] In this embodiment: the motor 1071 drives the cam 1072 to press the roller rod 1074 and the first spring 1076 to cooperate in operation, so that the roller rod 1074 can drive the hot air head 1066 to rotate through the connecting strip 1077. Through the cooperation between the support shaft 1063 and the inclined plate 1064, multiple hot air heads 1066 work together to achieve reciprocating motion. At this time, the hot air blower 1031 outputs hot air through the hot air head 1066. When the folded mattress enters the film packaging equipment 102 process, the hot air head 1066 group outputs high temperature through reciprocating motion to perform uniform high temperature sterilization on the folded mattress. At the same time, the folded mattress is also vibrated by the reciprocating tapping of the tapping frame 1065, which facilitates the removal of dust. With the help of the dust removal component 105, the dust removal operation of the folded mattress can be better performed, thereby improving the finished quality of the folded mattress.

[0048] Example 2: Refer to Figure 5-8 A folding mattress film-coating packaging device includes a sealing assembly 201, which includes two fixed brackets 2011. A conveying structure 104 is fixedly connected to the lower part of the two fixed brackets 2011. Electric push rods 2012 are fixedly connected to the upper and lower sides of the fixed brackets 2011. The heat sealing head 2013 can be heat-sealed by pushing the electric push rods 2012. One end of each pair of electric push rods 2012 is fixedly connected to the heat sealing head 2013. Two supports 2014 are fixedly connected to the upper part of the two fixed brackets 2011.

[0049] The positioning component 202 includes a support frame 2021, with both ends of the support frame 2021 fixedly connected to two heat-sealing heads 2013 above. Two positioning openings 2025 are provided on the support frame 2021. Two movable rods 2023 slide along the support frame 2021, and a connecting frame 2026 is fixedly connected to the bottom ends of the two movable rods 2023. Two second springs 2022 are fixedly connected between the top of the connecting frame 2026 and the support frame 2021. The elastic potential energy of the second springs 2022 allows for the positioning of the connecting frame 2026. To prevent movement, two elastic buckles 2024 are fixedly connected to the top of the connecting frame 2026. The top diameter of the elastic buckle 2024 is slightly larger than the diameter of the positioning port 2025. It has an annular opening at the bottom of its top and its top has elastic contraction, so that it can be deformed by squeezing and inserted into the positioning port 2025 until the top of the elastic buckle 2024 is out. At this time, the elastic buckle 2024 returns to its original position and can play the role of positioning the connecting frame 2026. This prevents the roller body 2041 from flipping relative to each other when the connecting frame 2026 is lifted again, which can easily lead to film wrinkles.

[0050] The smoothing component 204 includes a gear 2043, which is rotatably mounted below the threaded seat 2033 via a pin 2048. The gear 2043 can rotate smoothly via the pin 2048, thus ensuring stable meshing between the gear 2043 and the toothed plate 2046, allowing the roller frame 2042 to rotate smoothly. The gear 2043 meshes with the toothed plate 2046, and one side of the toothed plate 2046 is fixedly connected to the downward-extending end of the connecting frame 2026. Both sides of the toothed plate 2046 have sliding grooves, allowing it to slide along the guide rail 2047. The guide rail 2047 guides the toothed plate 2046, enabling it to move along the guide rail 2047 via the sliding grooves. 47. Smooth sliding: The guide rail 2047 is fixedly connected to the inner wall of the threaded seat 2033. The roller frame 2042 is fixedly connected to the pin 2048. Both ends of the roller frame 2042 are slidably connected to the sliding sleeves 2044. The sliding sleeves 2044 can slide on the roller frame 2042, allowing the roller body 2041 to rotate. The roller body 2041 can move through the sliding sleeves 2044, and the elastic force of the third spring 2045 can maintain the pre-tight force between the roller body 2041 and the film, so that the film can be smoothly spread from the middle. The roller body 2041 is rotatably installed between the two sliding sleeves 2044. The third spring 2045 is fixedly connected to one side of the sliding sleeve 2044, and one end of the third spring 2045 is fixedly connected to the side wall of the roller frame 2042.

[0051] The drive assembly 203 includes two screws 2031 with opposite threads. Rotation of the screws 2031 drives two threaded seats 2033 to move away from or towards each other. Both ends of the screws 2031 are rotatably mounted on the connecting frame 2026 via bearings. Threaded seats 2033 are threadedly connected to the screws 2031. Notches are provided on the upper two side walls of each threaded seat 2033. The two threaded seats 2033 are slidably connected to two guide bars 2034 through these notches. The guide bars 2034 guide the threaded seats 2033, allowing them to slide smoothly along the guide bars 2034 through the notches. The guide bars 2034 are fixedly connected to the connecting frame 2026. The two components are fixedly connected by a rope reel 2036. Both sides of the rope reel 2036 are fixedly connected to torsion springs 2035. The torque of the torsion springs 2035 can drive the automatic rotation, so that the rope reel 2036 can smoothly wind up the loose rope 2032. When the distance between the support frame 2021 and the connecting frame 2026 increases, the rope 2032 extends, thereby controlling the rope reel 2036 to drive the screw 2031 to rotate. Thus, the two threaded seats 2033 can move closer to each other, realizing the operation of the two smoothing components 204 flipping and resetting relative to each other. One end of the torsion spring 2035 is fixedly connected to the bearing near the rope reel 2036. The rope 2032 is wound around the outside of the rope reel 2036. The rope 2032 passes upward through the connecting frame 2026 and is fixedly connected to the support frame 2021.

[0052] In this embodiment: the sealing process is performed by the sealing assembly 201, causing the support frame 2021 to move downwards, so that the roller 2041 contacts the film outside the folded mattress. At this time, the support frame 2021 continues to move downwards, causing the rope 2032 to loosen. The torque of the torsion spring 2035 can then drive the rope disc 2036 and the screw 2031 to rotate, thereby causing the screw 2031 to drive the threaded seat 2033 to move. The two threaded seats 2033 move away from each other, causing the two gears 2043 to move and mesh with the toothed plate 2046, causing the two rollers 2041 to rotate in opposite directions. This allows the rollers 2041 to roll and smooth the film from the middle. After the rollers 2041 rotate, they can continue to be pushed forward by the threaded seats 2033, allowing the rollers 2041 to roll to the edge of the folded mattress. At this time, the wrinkled parts of the film can be unfolded and smoothed, improving the quality of the folded mattress film. The smoothing process can also expel the air inside the film, thereby preventing internal expansion from affecting the film quality again.

[0053] Example 3: Reference Figure 3-4 and Figure 6 A folding mattress laminating and packaging device includes a folding mattress packaging mechanism 100. The folding mattress packaging mechanism 100 includes a base 101. A conveying structure 104 and a laminating and packaging device 102 are fixedly installed on the top of the base 101. The laminating and packaging device 102 is internally provided with a reciprocating motion component 107 and an adjustable heat output component 106. The lower part of the adjustable heat output component 106 is connected to the reciprocating motion component 107. The adjustable heat output component 106 is located at the feed inlet of the laminating and packaging device 102 and is connected to a hot air component 103.

[0054] The mattress sealing mechanism 200 includes a sealing component 201, a positioning component 202 is disposed above the sealing component 201, a driving component 203 is disposed below the positioning component 202, and two smoothing components 204 are disposed below the driving component 203. The smoothing components 204 are located above the conveying structure 104. Folded mattresses are disposed above the conveying structure 104 and in the film packaging equipment 102.

[0055] In this embodiment: hot air is output by the hot air assembly 103 in conjunction with the adjustable hot air output assembly. At the same time, the adjustable hot air output assembly, in conjunction with the reciprocating motion assembly 107, enables the hot air head 1066 to reciprocate, thereby uniformly heating the folding mattress. The folding mattress is heated and then sealed by the sealing assembly 201. The drive can work with the smoothing assembly 204 to squeeze out the air inside the film, greatly reducing the air inside the film. After the sealing assembly 201 successfully seals the film, the residual heat of the folding mattress cools down. Through the principle of thermal expansion and contraction, the film shrinks and tightens onto the folding mattress, thereby helping to achieve a tight coating with the folding mattress and improving the coating effect of the folding mattress.

[0056] A method of using a folding mattress film-coating packaging device includes the following steps:

[0057] S1. When folding and wrapping the mattress, firstly, control the operation of the hot air blower 1031 so that it outputs high-temperature hot air through the hot air head 1066. Secondly, control the operation of the motor 1071. The motor 1071 drives the cam 1072 to rotate. The convex surface of the cam 1072 presses the roller rod 1074 to move, causing the roller rod 1074 to drive the first spring 1076 to deform through the connecting strip 1077. When the convex surface of the cam 1072 moves away from the roller rod 1074, the first spring 1076 drives the connecting strip 1077 to return to its original position until the convex surface... The wheel 1072 presses the roller rod 1074 again, causing the cam 1072 to work with the first spring 1076 to drive the connecting bar 1077 to reciprocate. The connecting bar 1077 drives the lower hot air head 1066 to reciprocate. At the same time, the lower hot air head 1066 drives the striking frame 1065 to reciprocate, causing the movable frames 1061 on both sides and the connecting shaft 1067 to follow the movement. Then, the support shaft 1063 works with the inclined plate 1064 to control the reciprocating movement of the remaining hot air heads 1066, so that multiple hot air heads 1066 can achieve reciprocating movement.

[0058] S2. Then, the folded mattress is fed into the inlet of the film packaging equipment 102, and the reciprocating hot air head 1066 performs uniform high-temperature sterilization on the folded mattress. At the same time, the folded mattress passes through the tapping frame 1065, which taps and vibrates the folded mattress. Meanwhile, the vacuum cleaner 1052 operates and performs dust collection through the frame-shaped dust suction head 1053, so that the dust enters the dust collection chamber 1051 for collection. After dust removal, the folded mattress is conveyed through the conveying mechanism in the film packaging equipment 102. During the conveying process, the folded mattress is filmed through a film. When the folded mattress is output from the outlet of the film packaging equipment 102, the heat sealing structure of the film packaging equipment 102 performs film sealing treatment.

[0059] S3. After the folded mattress is conveyed onto the conveyor structure 104, the electric push rod 2012 drives the heat sealing head 2013 to move, causing the support frame 2021 to follow the heat sealing head 2013 downwards, so that the roller 2041 contacts the film outside the folded mattress. At this time, the connecting frame 2026 continues to move downwards, causing the rope 2032 to loosen. The torque of the torsion spring 2035 then drives the rope disc 2036 to rotate and wind up the rope 2032. The rope disc 2036 also drives the screw 2031 to rotate. The two screws 2031 drive the two threaded seats 2033 to move away from each other, causing the gear 2043 to move accordingly. The gear 2043 meshes with the toothed plate 2046, causing the gear... 2043 drives the roller frame 2042 to flip, the roller body 2041 flips, and the roller body 2041 deforms by squeezing the third spring 2045 through the sliding sleeve 2044, so that the roller body 2041 can be smoothly flipped to the other side. At this time, the roller body 2041 continues to roll on the film, so that the film unfolds. When the connecting frame 2026 drives the positioning port 2025 to produce a squeezing motion with the elastic buckle 2024, the elastic buckle 2024 shrinks and deforms. The top of the elastic buckle 2024 passes through the positioning port 2025 and engages with the positioning port 2025 through deformation recovery. When the heat sealing heads 2013 on the upper and lower sides move relative to each other, they perform heat sealing operations on the films on both sides.

[0060] S4. After the film is coated, control the electric push rod 2012 to retract, so that the heat sealing head 2013 is reset. When the movable rod 2023 contacts the bracket 2014 upward, the movable rod 2023 applies force downward to the connecting frame 2026, so that the connecting frame 2026 applies force to the elastic buckle 2024, so that the elastic buckle 2024 deforms and passes through the positioning port 2025. At the same time, the rope 2032 extends, so that the rope disc 2036 rotates and drives the threaded seat 2033 to reset through the screw 2031, so that the two rollers 2041 flip and reset relative to each other, so as to carry out the next sealing operation.

[0061] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

When wrapping the folding mattress, firstly, control the operation of the hot air blower (1031) so that the hot air blower (1031) outputs high-temperature hot air through the hot air head (1066). Secondly, control the operation of the motor (1071). The motor (1071) drives the cam (1072) to rotate. The convex surface of the cam (1072) presses the roller rod (1074) to move, so that the roller rod (1074) drives the first spring (1076) to deform through the connecting strip (1077). When the convex surface of the cam (1072) moves away from the roller rod (1074), the first spring (1076) drives the connecting strip (1077) to return to its original position until the convex surface... The wheel (1072) presses the roller rod (1074) again, causing the cam (1072) to work with the first spring (1076) to drive the connecting bar (1077) to reciprocate. The connecting bar (1077) drives the lower hot air head (1066) to reciprocate.

S2. Then, the folded mattress is fed into the inlet of the film packaging equipment (102), and the reciprocating hot air head (1066) sterilizes the folded mattress evenly at high temperature. At the same time, the folded mattress passes through the tapping frame (1065), which taps and vibrates the folded mattress. Meanwhile, the vacuum cleaner (1052) runs through the frame-shaped vacuum head (1053) to vacuum the dust, so that the dust enters the dust collection chamber (1051) for collection. After dust removal, the folded mattress is conveyed through the conveying mechanism in the film packaging equipment (102). The folded mattress is covered with film during the conveying process. When the folded mattress is output from the outlet of the film packaging equipment (102), the heat sealing structure of the film packaging equipment (102) is sealed. S3. After the folding mattress is conveyed onto the conveying structure (104), the electric push rod (2012) is controlled to move the heat sealing head (2013), causing the support frame (2021) to follow the heat sealing head (2013) downwards, so that the roller (2041) contacts the film outside the folding mattress. At this time, the connecting frame (2026) continues to move downwards, causing the rope (2032) to loosen. At this time, the torque of the torsion spring (2035) drives the rope disc (2036) to rotate and wind up the rope (2032). The rope disc (2036) also drives the screw (2031) to rotate. The two screws (2031) drive the two threaded seats (2033) to move away from each other, causing the gear (2043) to move accordingly. The gear (2043) meshes with the toothed plate (2046), so that... The gear (2043) drives the roller frame (2042) to rotate, the roller body (2041) rotates, and the roller body (2041) deforms by squeezing the third spring (2045) through the sliding sleeve (2044), so that the roller body (2041) can be smoothly rotated to the other side. At this time, the roller body (2041) continues to roll on the film, so that the film unfolds. When the connecting frame (2026) drives the positioning port (2025) and the elastic buckle (2024) to compress, the elastic buckle (2024) contracts and deforms. The top of the elastic buckle (2024) passes through the positioning port (2025) and engages with the positioning port (2025) through deformation recovery. When the upper and lower heat sealing heads (2013) move relative to each other, they heat seal the film on both sides. S4. After the film is coated, control the electric push rod (2012) to retract, so that the heat sealing head (2013) is reset.
