Description

Technical Field

[0001] This utility model relates to the field of mattress packaging technology, and in particular to an automatic mattress packaging machine. Background Technology

[0002] After the mattress is finished, it usually needs to be compressed and packaged before leaving the factory due to its large size. However, the existing automatic mattress packaging machine has a relatively simple overall structure, and it is quite laborious to change the film roll.

[0003] The technical solution disclosed in Chinese Patent No. CN222022970U involves setting up two sets of support plates. On the support plates, guide rollers that are controlled by a bidirectional module A to move closer or further away from the film, as well as a heat-sealing plate B13, are set up. When the film on the current film roll is not used up, the guide rollers on both sides will not interfere with the film conveying while maintaining the clamping state of the film. At the same time, the heat-sealing plate B will not come into contact with the film. After the film on the current film roll is used up, the end of the old film roll is heat-sealed to the front end of the new film through the heat-sealing plate B, which can realize the film replacement operation, saving time and efficiency.

[0004] However, the device still has shortcomings: it requires manual adjustment of the mattress position so that both sides can be wrapped by the film, which is time-consuming. In addition, the device lacks a structure for positioning the packaging film, which makes it easy for the packaging film to slide laterally along the roller during release, which can easily cause wrinkles on the surface of the mattress and affect the appearance after compression packaging.

[0028] like Figures 1-6As shown, this utility model proposes an automatic mattress packaging machine, including a frame 1, a support 6, a fixing frame 13, a clamping plate 16, a drive assembly D, and a sealing mechanism. A support plate 2 is mounted on the frame 1, and a conveyor belt 4 is mounted on the support plate 2. A drive assembly A is mounted on the frame 1 to drive the conveyor belt 4. The drive assembly A includes a transmission roller 3 and a motor 5. The transmission roller 3 includes a driving roller and a driven roller, which are located on opposite sides of the support plate 2 and rotatably connected to the frame 1. The driving roller and the driven roller are connected via the conveyor belt 4. The motor 5 is connected to the frame 1, and its output end is connected to the roller shaft of the driving roller. A movable frame 7 is slidably mounted on the support 6. Two heat-sealing plates A11 are symmetrically and slidably mounted on the movable frame 7. Two sets of sliders 9 are symmetrically and slidably mounted on the movable frame 7, with two sliders in each set. Spring rods A10 are mounted on the sliders 9, and each heat-sealing plate A11 is connected to the movable end of the corresponding two spring rods A10. The movable frame 7 is equipped with a drive assembly B that drives the heat-sealing plates A11 on both sides to move synchronously closer or further away. The drive assembly B includes two bidirectional modules A12, and the two sets of sliders 9 are respectively connected to the corresponding output ends on the corresponding bidirectional modules A12. The support 6 is equipped with a drive assembly C that drives the movable frame 7 to rise and fall. The drive assembly C includes, but is not limited to, a hydraulic cylinder A8. The body of the hydraulic cylinder A8 is connected to the support 6, and the output end of the hydraulic cylinder A8 is connected to the movable frame 7. The fixed frame 13 is connected to the loading end of the frame 1. The fixed frame 13 is equipped with several guide rollers A20, and two sets of slots A131 are arranged in parallel on the fixed frame 13. Each set of slots A131 contains two slots, and the two sets of slots A131 are located on the upper and lower sides of the bearing surface of the conveyor belt 4, respectively. A support roller 15, which is at the same height as the bearing surface of the conveyor belt 4, is rotatably mounted on the fixed frame 13. Two clamping plates 16 are symmetrically arranged on the support roller 15 and slidably connected to it. A set of clamping rollers 17 are rotatably arranged on the side of the clamping plates 16 that are close to each other. The distance between the clamping rollers 17 on both sides is less than the width of the film roll. A turntable 19 for adjusting the centering of the film roll is provided on the clamping plates 16. A U-shaped plate 161 is connected to each end of the clamping plate 16. The opening of each U-shaped plate 161 is consistent with the opening of the corresponding slot A131. The turntable 19 is rotatably connected to the U-shaped plate 161. A slot B191 that matches the opening of the U-shaped plate 161 is provided on the turntable 19. When the film roll slides into place in the slot A131, the film roll is coaxial with the turntable 19. A counterweight 192 is provided on the arc surface of the turntable 19. The drive assembly D includes, but is not limited to, a bidirectional module B18. The body of the bidirectional module B18 is connected to the fixing frame 13. The two output ends of the bidirectional module B18 are connected to a slide block. The two slide blocks are connected to the clamping plates 16 on the corresponding sides. The edge sealing mechanism is connected to the fixed frame 13. The edge sealing mechanism includes a support base 21, a movable plate 23, a cutter 24, a heat-sealing plate B26, and a hydraulic cylinder B28.A support base 21 is mounted on a fixed frame 13, with its upper surface flush with the bearing surface of the conveyor belt 4. A guide roller B22 is rotatably connected to the support base 21. A mounting base 27 is mounted on the fixed frame 13 above the support base 21, with a guide rod slidably connected to the mounting base 27. A movable plate 23 is connected to the lower end of the guide rod, and a cutter 24 is connected to the movable plate 23. Two sets of spring rods B25 are arranged parallel to each other on the movable plate 23, and two heat-sealing plates B26 are respectively connected to the movable ends of the corresponding spring rods B25, with the two heat-sealing plates B26 located on either side of the cutter 24. The body of a hydraulic cylinder B28 is connected to the mounting base 27, and the output end of the hydraulic cylinder B28 is connected to the movable plate 23. In operation, the sealing mechanism fuses the film at both ends of the mattress and cuts it at the middle of the interface.

[0029] In this embodiment, the film roll is first installed. During operation, the two ends of the two film rollers are respectively inserted into the corresponding slots A131. Since the turntable 19 is equipped with a counterweight 192, the orientation of the slot B191 of the turntable 19 is the same as the orientation of the slot A131 in the initial state, and the film rollers are naturally inserted into the slots B191. Then, the bidirectional module B18 is activated. The bidirectional module B18 drives the clamping plates 16 on both sides to move closer to each other until the turntable 19 presses against the two ends of the film roll. The ends of the film on the upper and lower film rolls are then pulled around the guide rollers A20. The end of the lower film is pulled around the guide roller B22 and brought to fit against the upper surface of the support 21, while the upper film is pulled to fit against the upper surface of the lower film. Then, the hydraulic cylinder B28 is activated, and the hydraulic cylinder B28 presses down the movable plate 23, so that the hot-welding plate B26 performs two-stage fusion welding on the upper and lower films. The cutter 24 cuts off the fusion parts at both ends from the middle, thus completing the fusion welding of the upper and lower films. Activate the bidirectional module A12 to adjust the spacing of the two heat-sealing plates A11 to match the packaging film and mattress. Then, place one end of the mattress on the support roller 15 and between the two clamping rollers 17. The clamping rollers 17 slide and limit the two ends of the mattress. Then, the front end of the mattress contacts the packaging film and slides along the conveyor belt 4 after sliding onto the conveyor belt 4. At this time, the top, bottom, and front end of the mattress are covered with the packaging film. Activate the hydraulic cylinder B28 again to seal the ends of the top and bottom films at the rear. Then, the mattress is transported to the processing station below the movable frame 7. Activate the hydraulic cylinder A8 to press down the movable frame 7. The bottom plane of the movable frame 7 compresses the mattress. The heat-sealing plate A11 contacts the support plate 2 during the downward pressure from above the film. Then, the movable frame 7 continues to lower its height, and the spring rod A10 retracts adaptively. After the mattress is compressed to the correct position, the heat-sealing plates A11 on both sides seal the edges of the top and bottom films on both sides of the mattress.

[0030] Example 2

[0031] like Figure 1 and Figure 3As shown, the automatic mattress packaging machine proposed in this utility model, compared with the first embodiment, has a damped sliding blocking block 14 on the fixed frame 13. The blocking block 14 is inserted into the corresponding side slot A131 and slidably connected to the fixed frame 13. Each blocking block 14 is provided with a lever that is slidably connected to the fixed frame 13.

[0032] In this embodiment, the blocking block 14 is used to block and limit the roller shaft of the film roll, so that it always remains coaxial with the turntable 19. When the film roll needs to be replaced, the pull plate is pulled up, and the pull plate drives the blocking block 14 to slide, so that the opening of the slot A131 is opened. At this time, the film roll can be freely replaced along the slot A131.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
