Description

Technical Field

[0001] This invention relates to the field of mattress packaging technology, and in particular, to a mattress packaging device. Background Technology

[0002] Mattresses need to be packaged during the manufacturing and transportation process to protect them.

[0003] Currently, mattresses are typically packaged manually. However, the large size of mattresses makes it inconvenient for workers to flip them over, resulting in low packaging efficiency. When using a packaging machine to wrap the mattresses with plastic film, after one mattress is wrapped, the plastic film is cut with a cutter. Workers then need to reprocess the cut plastic film, clamping it back onto the clamping assembly before packaging the next mattress.

[0004] To facilitate mattress storage, after the mattress is wrapped in plastic film, it is transported to a vacuum compressor for compression and vacuuming to reduce its volume and facilitate transportation. The plastic film packaging machine and the vacuum compressor need to be placed in sequence, occupying considerable space, and the use of two sets of equipment also increases the overall cost.

[0005] Therefore, how to design a packaging device for wrapping and compressing mattresses with plastic film has become a technical problem that urgently needs to be solved by people in this field. Summary of the Invention

[0006] In order to solve at least one of the technical problems mentioned in the background art, the present invention aims to provide a mattress packaging device that solves the problem of occupying a large space when two sets of devices are used at the same time, while reducing the equipment cost for manufacturers.

[0013] Furthermore, the bottom positive pressure plate is provided with a cutting groove for inserting a cutting blade. The bottom positive pressure plate also includes a third positive pressure plate and a fourth positive pressure plate, which are located on both sides of the cutting groove. The length of the cutting blade and the cutting groove is greater than the width of the plastic film.

[0014] Furthermore, the pressing area is provided with an upper frame fixed on the base, and also includes a top pressing module. The top pressing module includes a pusher frame, a pusher cylinder, and a top pressing roller. The pusher cylinder is fixedly installed on the upper frame, and the cylinder rod of the pusher cylinder is fixedly connected to the pusher frame. The pressing base is provided with a vertical clearance groove. The pusher frame extends downward through the clearance groove, and the top pressing roller is rotatably installed on the pusher frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a feeding drive mechanism to move the mattress from the feeding area to the pressing area. During the movement of the mattress, the plastic film between the push pressing seat and the mounting seat is folded in half and covers the upper and lower sides of the mattress. Then, the lifting mechanism moves the pressing seat downward to compress the mattress and reduce its thickness. At the same time, the push mechanism pushes the first hot pressing plate group downward to abut against the second hot pressing plate group, realizing the hot pressing and sealing of the plastic film at the three openings of the mattress. At the same time, the cutting knife cuts the plastic film sealed at the positive pressing plate. At this time, the waste material winding module winds up the plastic film to prevent the hot-pressed plastic film from being used for sealing the next mattress, thus improving the aesthetics of the mattress sealing. This equipment integrates the mattress compression and sealing functions, reducing the initial investment cost of the production line and reducing the space occupied by the production line equipment.

[0019] The top pressure plate, bottom pressure plate, cutting blade, and waste winding module enable continuous feeding of plastic film, saving the manual clamping process after cutting the plastic film and improving the packaging efficiency of mattresses. Attached Figure Description

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This embodiment provides a mattress packaging equipment that simplifies the mattress packaging production line, reduces mattress packaging costs, and improves mattress packaging efficiency.

[0039] like Figure 1 and Figure 2 As shown, the device includes a base 1, on which a feeding drive mechanism for moving the mattress 8 is provided. An upper frame 15 is fixedly mounted on the top of the base 1, forming a pressing area with the base 1. The area in front of the upper frame 15 serves as the feeding area. The upper frame 15 is equipped with a pressing seat 3 and a lifting mechanism for driving the pressing seat 3 to rise and fall. The pressing seat 3 is equipped with a C-shaped first hot press plate assembly 361, and the base 1 is equipped with a second hot press plate assembly 43 adapted to the first hot press plate assembly 361. Figure 5 and Figure 12 As shown, the pressing base 3 has a vertically penetrating clamping groove 31 on the side near the feeding area. A mounting base 2 is located on the base 1 directly below the clamping groove 31. The mounting base 2 has a vertically penetrating feeding groove 21. A waste material winding module is also located on the top of the pressing base 3. A plastic film roll 9 is rotatably mounted on the base 1. The plastic film 91 on the plastic film roll 9 passes through the feeding groove 21 and the clamping groove 31 and is fixed to the waste material winding module. Specifically, the first hot press plate assembly 361 includes a top side pressure plate 3611 and a top positive pressure plate 3612. The top side pressure plate 3611 is located on the first hot press plate. The two sides of the assembly 361 are used to heat-press and seal the plastic film 91 on both sides of the mattress 8. The top positive pressure plate 3612 is connected to the top side pressure plates 3611 on both sides to seal the plastic film 91 at the ends of the mattress 8. The second heat-pressing plate assembly 43 includes a bottom side pressure plate 431 and a bottom positive pressure plate 432. The bottom side pressure plate 431 is aligned with the top side pressure plate 3611, and the bottom positive pressure plate 432 is aligned with the top positive pressure plate 3612. Specifically, one of the top positive pressure plate 3612 or the bottom positive pressure plate 432 is provided with a cutting blade 3613 for cutting the plastic film 91.

[0040] With the above setup, initially, the plastic film 91 on the plastic film roll 9 passes through the feeding groove 21 and the clamping groove 31 and is fixed on the waste winding module; the mattress 8 is placed on the feeding area of ​​the base 1, and then the feeding drive mechanism is driven to make the mattress 8 move backward. Figure 9As shown, as the mattress 8 moves, its end begins to abut against the plastic film 91 between the mounting base 2 and the pressing base 3, pushing against the plastic film 91. Under the action of the feeding drive mechanism, the mattress 8 moves to directly below the pressing base 3 in the pressing area. At this time, as... Figure 11 As shown, the plastic film 91 is folded in half and wrapped around the upper and lower sides of the mattress 8. At this time, the operation of the feeding drive mechanism is stopped. Then, the lifting mechanism drives the pressing seat 3 to move downward, and the pressing seat 3 compresses the mattress 8, thereby reducing the thickness of the mattress 8. When the pressing seat 3 is lowered to a certain distance, the first hot press plate group 361 on the pressing seat 3 and the second hot press plate group 43 on the base 1 perform hot press sealing on the three openings of the mattress 8. Figure 12 As shown, at the same time, the cutting blade 3613 cuts the plastic film 91 near the feeding area, separating the plastic film 91 wrapped around the mattress 8 from the plastic film 91 on the plastic film roll 9. At this time, the plastic film 91 on the waste winding module near the feeding area and the plastic film 91 on the plastic film roll 9 are pressed together by the top positive pressure plate 3612 and the bottom positive pressure plate 432. The waste winding module rotates a certain number of times to wind up the pressed position of the two. Then, the lifting mechanism drives the pressing seat 3 to move upward. At this time, the waste winding module stops winding, the plastic film 91 on the plastic film roll 9 is unloaded, the feeding drive mechanism runs, and drives the mattress 8 that has been pressed in the pressing area to move backward and then drives the mattress 8 on the feeding area to move to the pressing area again, so as to package and press the next mattress 8. In this solution, the plastic film wrapping process of mattress 8 and the compression process of mattress 8 are processed simultaneously, which reduces the space occupied by the mattress 8 packaging equipment, reduces equipment costs, and improves the packaging efficiency of mattress 8.

[0041] In order to drive the mattress 8, in this embodiment, as follows: Figure 1 and Figure 2 As shown, the feeding drive mechanism includes a first conveying roller group 11 and a second conveying roller group 12. Specifically, the first conveying roller group 11 is installed on the feeding area of ​​the base 1, and the second conveying roller group 12 is installed on the pressing area of ​​the base 1. Specifically, adjacent rollers of the first conveying roller group 11 are driven by a chain, and adjacent rollers of the second conveying roller group 12 are driven by a chain. The feeding drive mechanism also includes a first motor 102, wherein the output shaft of the first motor 102 is fixedly connected to the rotating shaft of any roller in the first conveying roller group 11. The first conveying roller group 11 and the second conveying roller group 12 are connected by a transmission mechanism 103, which enables the synchronous rotation of the first conveying roller group 11 and the second conveying roller group 12.

[0042] Specifically, such as Figure 2As shown, in this embodiment, the transmission mechanism between the first conveyor roller group 11 and the second conveyor roller group 12 uses a belt drive to transmit power. However, the transmission mechanism 103 is not limited to belt drive; it can also use chain drive or gear drive to achieve synchronous rotation of the first conveyor roller group 11 and the second conveyor roller group 12.

[0043] Because the feeding drive mechanism moves the mattress 8 from the loading area to the pressing area, when the mattress 8 enters the pressing area, it needs to stay there for a period of time to allow the pressing seat 3 to compress the mattress 8 and perform heat pressing on the plastic film 91; in order to stop the mattress 8 at a designated position in the pressing area, in this embodiment, as Figure 2 and Figure 16 As shown, a position sensor 105 is fixedly installed on the side of the pressing area base 1 away from the feeding area. A central control unit 100 is also provided on the base 1. The position sensor 105 and the first motor 102 are electrically connected to the central control unit 100.

[0044] With the above settings, the first motor 102 rotates to provide power to the first conveying roller group 11 and the second conveying roller group 12, which facilitates the movement of the mattress 8 in the loading area to the pressing area. When the mattress 8 enters the designated position in the pressing area, the position sensor 105 detects that the mattress 8 has reached the position and transmits a signal to the central control unit 100 to stop the rotation of the first motor 102, thereby controlling the mattress 8 to continue moving and achieving precise positioning of the mattress 8.

[0045] In order to achieve the lifting and lowering of the pressing seat 3, in this embodiment, the lifting mechanism includes a hydraulic cylinder 6, an oil supply line and a solenoid valve for driving the extension and retraction of the hydraulic rod in the hydraulic cylinder 6. The solenoid valve is electrically connected to the central control unit 100. The central control unit 100 controls the movement of the valve core of the solenoid valve, thereby controlling the extension and retraction of the hydraulic rod in the hydraulic cylinder 6, and thus controlling the lifting and lowering of the pressing seat 3. Specifically, the hydraulic cylinder 6 is fixed on the upper frame 15, and the hydraulic rod of the hydraulic cylinder 6 is fixedly connected to the pressing seat 3.

[0046] To achieve stable lifting and lowering of the pressing seat 3, in this embodiment, as follows: Figure 1 , Figure 2 and Figure 9 As shown, the upper frame 15 is provided with a guide hole 151 that runs vertically through it. A guide rod 61 is slidably connected in the guide hole 151. The guide rod 61 is vertically arranged and has two sets located on both sides of the hydraulic cylinder 6. The ends of the guide rods 61 are fixedly connected to the top wall of the pressing seat 3.

[0047] In order to achieve the installation of the plastic film roll 9, in this embodiment, as follows: Figure 1 and Figure 2As shown, the bottom wall of the base 1 of the feeding area is fixed with a downwardly extending feeding rack 101, wherein the feeding rack 101 is provided with an upwardly inclined feeding groove 1011. The plastic film roll 9 is installed on the rotating shaft, and then the rotating shaft slides down to the bottom through the opening of the feeding groove 1011 and abuts against the bottom wall of the feeding groove 1011. When the mattress 8 moves forward, it can push the plastic film 91 between the clamping groove 31 and the mounting base 2 to extend to the pressing area side, thereby covering the upper and lower sides of the mattress 8. At the same time as the mattress 8 moves, the rotating shaft of the plastic film roll 9 starts to rotate to feed the plastic film 91.

[0048] It is worth noting here that setting the feeding trough 1011 to an inclined state can solve the problem of the plastic film roll 9 detaching from the feeding trough 1011 during rotation.

[0049] To achieve the installation of mounting base 2, in this embodiment, as follows: Figure 2 As shown, a positioning groove 13 is provided between the first conveying roller group 11 and the second conveying roller group 12 of the base 1. The mounting seat 2 is installed in the positioning groove 13, and the top wall of the mounting seat 2 is flush with the height of the rollers in the first conveying roller group 11 and the second conveying roller group 12.

[0050] In order to install the second hot-press plate assembly 43 on the base 1, in this embodiment, as follows: Figure 2 and Figure 14 As shown, the base 1 of the pressing area is provided with a mounting groove 14 arranged along the length of the base 1. A mounting bracket 16 is fixedly installed inside the mounting groove 14. The top wall of the mounting bracket 16 is provided with a downwardly oriented groove. Specifically, the mounting groove 14 has two sets located on both sides of the second conveyor roller group 12. The groove of the mounting bracket 16 is used to place the bottom side pressure plate 431 of the second hot press plate group 43. Figure 4 As shown, the top wall of the mounting base 2 is provided with a downwardly recessed hot press groove 22, wherein the bottom positive pressure plate 432 of the second hot press plate group 43 is installed in the hot press groove 22.

[0051] In order to connect the bottom side pressure plate 431 and the bottom positive pressure plate 432 to achieve closure during the hot pressing process of the plastic film 91, in this embodiment, as follows: Figure 4 As shown, the mounting base 2 is also provided with a connecting groove 23 that connects the hot pressing groove 22 with the groove on the mounting bracket 16. The bottom side pressure plate 431 extends through the connecting groove 23 into the hot pressing groove 22 and is connected to the bottom positive pressure plate 432.

[0052] In this embodiment, a cutting blade 3613 for cutting the plastic film 91 is mounted on the first hot press plate assembly 361. In order to cut the plastic film 91, such as... Figure 8 , Figure 12 and Figure 13As shown, the bottom positive pressure plate 432 is provided with a cutting groove 433 for the cutting blade 3613 to be inserted. When the cutting blade 3613 cuts the plastic film 91 between the top positive pressure plate 3612 and the bottom positive pressure plate 432, the cutting blade 3613 is inserted into the cutting groove 433.

[0053] To prevent the cutting blade 3613 from contacting the bottom wall of the hot press groove 22 and damaging the blade, in this embodiment, as follows: Figure 4 As shown, the bottom wall of the hot pressing groove 22 is provided with a downwardly recessed shearing clearance groove 221, wherein, after the second hot pressing plate group 43 is installed, the cutting groove 433 and the shearing clearance groove 221 are aligned vertically.

[0054] In this embodiment, in order to ensure that the plastic film 91 is completely cut, the length of the bottom positive pressure plate 432 is greater than the width of the plastic film 91. Similarly, the lengths of the cutting blade 3163 and the cutting groove 433 are both greater than the width of the plastic film 91.

[0055] To facilitate the installation of the plastic film 91, the plastic film 91 is guided. In this embodiment, for example... Figure 1 , Figure 5 , Figure 7 and Figure 9 As shown, a third guide roller 901 is rotatably mounted on the base 1 directly below the feeding trough 21, a first guide roller 201 is rotatably mounted inside the feeding trough 21, and a second guide roller 301 is rotatably mounted inside the clamping groove 31. The top wall of the first guide roller 201 is flush with the top wall of the mounting base 2. When the mattress 8 pushes the plastic film 91 forward and presses the plastic film 91 under the mattress 8, it can minimize the friction between the plastic film 91 and the edge of the feeding trough 21, thereby reducing the occurrence of damage to the plastic film 91.

[0056] With the above setup, the plastic film 91 on the plastic film roll 9 passes sequentially around the third guide roller 901, the first guide roller 201 and the second guide roller 301, and is then fixed on the waste material winding module.

[0057] Specifically, in this embodiment, such as Figure 5 , Figure 7 and Figure 9As shown, the waste material winding module includes a waste material winding frame 40, a waste material winding roller 41, and a second motor 42. The waste material winding frame 40 is fixed to the top wall of the pressing base 3. The waste material winding roller 41 is rotatably mounted on the waste material winding frame 40. The second motor 42 is fixed to the waste material winding frame 40, and its output shaft is fixedly connected to the waste material winding roller 41. The plastic film 91 is fixed to the waste material winding roller 41. The second motor 42 is electrically connected to the central control unit 100, which controls the rotation of the second motor 42 to wind up the waste material cut from the hot-pressed plastic film 91.

[0058] To prevent the waste material winding module from colliding with the upper frame 15 during the rising of the pressing seat 3, in this embodiment, as follows: Figure 5 As shown, the waste winding frame 40 is located on both sides of the clamping groove 31, and the end of the waste winding frame 40 extends obliquely upward to the upper side of the feeding area. At this time, the waste winding roller 41 is located directly above the feeding area, thereby preventing the waste winding module from touching the upper frame 15.

[0059] When the mattress 8 moves from the loading area to the pressing area, the lifting mechanism moves the pressing seat 3 to its highest position, facilitating the movement of the mattress 8 into the pressing area. At this time, the mattress 8 pushes against the plastic film 91, causing the plastic film 91 on the upper side of the mattress 8 to tilt. Figure 9 As shown by the dotted line, the upper plastic film 91 does not adhere to the upper surface of the mattress 8. When the mattress 8 is compressed, a large number of air bubbles will exist in the gap between the upper plastic film 91 and the mattress 8, resulting in poor compression effect of the mattress 8.

[0060] Therefore, in this embodiment, as Figure 3 , Figure 9 and Figure 11 As shown, the upper frame 15 is provided with a top pressing module 5 for pushing the plastic film 91 on the upper side of the mattress 8. The top pressing module 5 includes a top pushing frame 51, a top pushing cylinder 52, and a top pressing roller 53. Specifically, the top pressing module 5 is located near the pressing area and downstream of the mounting base 2. Here, downstream is relative to the flow direction of the mattress 8. Specifically, the top pushing frame 51 is installed on the upper frame 15, the top pushing cylinder 52 is fixedly installed on the top wall of the upper frame 15, the cylinder rod of the top pushing cylinder 52 is fixedly connected to the top pushing frame 51, and the top pressing roller 53 is rotatably installed on the top pushing frame 51. When the mattress 8 is packaged, the top pressing roller 53 abuts against the top wall of the mattress 8.

[0061] With the above setup, during the packaging of the mattress 8, the height of the push-up frame 51 is adjusted by the push-up cylinder 52, thereby adjusting the height of the top pressure roller 53. This allows the top pressure roller 53 to be suitable for mattresses 8 of different thicknesses. When the mattress 8 moves onto the pressing area, as... Figure 11As shown, the top pressure roller 53 pushes the plastic film 91 on the upper side of the mattress 8, so that the plastic film 91 adheres to the top wall of the mattress 8, reducing the gap between the plastic film 91 and the top wall of the mattress 8.

[0062] To further accommodate mattresses 8 of different thicknesses, in this embodiment, such as Figure 3 As shown, the side wall of the pusher 51 is provided with an adjustment groove 511 arranged longitudinally. The adjustment groove 511 is provided with an adjustment block 531 that slides up and down. The side wall of the adjustment block 531 is slidably connected to the side wall of the adjustment groove 511. The top pressure roller 53 is installed on the adjustment block 531. The adjustment groove 511 also includes a fourth spring 54. One end of the fourth spring 54 is fixedly connected to the bottom wall of the adjustment groove 511, and the other end of the fourth spring 54 is fixedly connected to the adjustment block 531.

[0063] With the above settings, when the thickness of the mattress 8 is large, exceeding the gap between the top pressure roller 53 and the top wall of the base 1, as the mattress 8 enters, the mattress 8 abuts against the bottom wall of the top pressure roller 53 and pushes the top pressure roller 53 and the adjusting block 531 to slide upward along the adjusting groove 511 and stretch the fourth spring 54, so as to meet the problem of packaging mattresses 8 of different thicknesses.

[0064] To prevent the top pressing module 5 from contacting the pressing seat 3, in this embodiment, as follows: Figure 6 and Figure 9 As shown, the pressing seat 3 is provided with a vertically penetrating relief groove 32. When the top pressing module 5 is installed, the top pushing frame 51 extends vertically downward through the relief groove 32.

[0065] If the first hot-pressing plate group 361 is directly installed on the bottom wall of the pressing seat 3, when the pressing seat 3 presses the mattress 8, the first hot-pressing plate group 361 can come into contact with the plastic film 91 on the mattress 8. At this time, the first hot-pressing plate group 361 can easily damage the plastic film 91. Therefore, before hot-pressing the plastic film 91, it is necessary to hide the first hot-pressing plate group 361 and the second hot-pressing plate group 43 to prevent the hot-pressing plate group from coming into contact with the plastic film 91 in advance.

[0066] Specifically, in this embodiment, when installing the second hot press plate group 43, since the bottom side pressure plate 431 and the bottom positive pressure plate 432 are located in the groove of the mounting frame 16 and the hot press groove 22 respectively, the top wall of the second hot press plate group 43 is lower than the bottom wall of the first conveying roller group 11 and the second conveying roller group 12, preventing the plastic film 91 from contacting the second hot press plate group 43 in advance.

[0067] In order to achieve the installation of the first hot-press plate assembly 361, in this embodiment, as follows: Figure 6As shown, the top wall of the pressing seat 3 is provided with a downwardly recessed C-shaped groove 33. Specifically, the C-shaped groove 33 includes a first groove chamber 331 for the installation of the top side pressure plate 3611 and a second groove chamber 332 for the installation of the top positive pressure plate 3612. The first groove chamber 331 has two chambers, both of which are connected to the second groove chamber 332. The bottom wall of the C-shaped groove 33 is also provided with a slot for the first hot pressure plate group 361 to pass through downward. The first hot pressure plate group 361 is installed in the C-shaped groove 33. When the pressing seat 3 stops compressing the mattress 8, the first hot pressure plate group 361 is stored in the C-shaped groove 33. When the pressing seat 3 moves to the bottom limit position and completes the pressing of the mattress 8, the first hot pressure plate group 361 moves downward and adapts to the second hot pressure plate group 43 to heat press the plastic film 91, sealing the mattress 8 in the cavity formed by the plastic film 91.

[0068] In order to enable the first hot press plate group 361 to pass through the slot and cooperate with the second hot press plate group 43 to hot press the plastic film 91, the pressing base 3 is also provided with a third slot 34 that connects the two first slots 331 on both sides. The third slot 34 is parallel to the second slot 332. Push plates 35 are fixedly installed on the two top side pressure plates 3611 on both sides, and a second spring 342 is also included. Figure 6 , Figure 9 and Figure 14 As shown, one end of the second spring 342 is fixedly connected to the bottom wall of the third chamber 34, and the other end of the second spring 342 is fixedly connected to the bottom wall of the push plate 35. The side wall of the pressing seat 3 is also provided with an installation slot 341 aligned with the third chamber 34. A push rod 39 is rotatably installed in the installation slot 341. Specifically, the push rod 39 is L-shaped. One end of the push rod 39 abuts against the top wall of the push plate 35, and the other end of the push rod 39 extends to the bottom wall of the pressing seat 3 and continues to extend downward. An extension frame plate 104 suitable for the push rod 39 is also fixedly provided on the base 1 of the pressing area.

[0069] With the above settings, as Figure 9 and Figure 11 As shown, when the hydraulic cylinder 6 is in the retracted state, the pressing seat 3 is located above the mattress 8. At this time, the second spring 342 pushes the push plate 35 upward, so that the first hot pressing plate assembly 361 is inside the C-shaped groove 33. After the hydraulic cylinder 6 pushes the pressing seat 3 downward to complete the compression of the mattress 8, as shown... Figure 12 and Figure 14 As shown, at this time, the end of the push rod 39 abuts against the extension plate 104, thereby causing the push rod 39 to rotate around its own rotation center, so that the other end of the push rod 39 moves downward and pushes the push plate 35 downward, compressing the second spring 342. At this time, the first hot press plate group 361 extends out of the slot and cooperates with the second hot press plate group 43 to realize the pressing of the plastic film 91.

[0070] To achieve the installation of push rod 39, specifically, as follows: Figure 14 As shown, the push rod 39 includes a first push rod 391, a second push rod 392, and a rotating shaft 393. One end of the first push rod 391 is fixedly connected to one end of the second push rod 392 to form an L-shape. The rotating shaft 393 is installed at the connection between the first push rod 391 and the second push rod 392 and is rotatably connected to the side wall of the mounting slot 341. The second push rod 392 abuts against the top wall of the push plate 35. The first push rod 391 extends outward and extends to the lower side of the bottom wall of the pressing seat 3.

[0071] With the above settings, after the mattress 8 is compressed, the first push rod 391 abuts against the extension frame plate 104, causing the first push rod 391 to rotate around the rotation axis 393. At this time, the second push rod 392 pushes downward, thereby compressing the second spring 342 and completing the downward movement of the first hot press plate group 361, thus completing the hot pressing and sealing operation of the plastic film 91. When the hydraulic cylinder 6 drives the pressing seat 3 to rise, the first push rod 391 gradually disengages from the extension frame plate 104. At this time, the second spring 342 pushes the push plate 35 upward, thereby causing the first hot press plate group 361 to retract back into the C-shaped groove 33.

[0072] Specifically, the pressing seat 3 is also equipped with a sealing cover 38 to seal the C-shaped groove 33.

[0073] Since the cutting blade 3613 is mounted on the first hot press plate assembly 361, and the bottom positive pressure plate 432 of the second hot press plate assembly 43 includes a third positive pressure plate 4321 and a fourth positive pressure plate 4322, in order to align the top positive pressure plate assembly 3612 with the bottom positive pressure plate 432, in this embodiment, as follows: Figure 15 As shown, the top positive pressure plate assembly 3612 includes a first positive pressure plate 36121 and a second positive pressure plate 36122. A cutting blade 3613 is fixedly connected to the two top side pressure plates 3611, and the second positive pressure plate 36122 is fixedly mounted on the cutting blade 3613. The second positive pressure plate 36122 and the fourth positive pressure plate 4322 are aligned for heat-sealing the plastic film 91 at the end of the mattress 8. The first positive pressure plate 36121 is positioned relative to the second positive pressure plate 36122 at the cutting blade. The other side of the cutter 3163 is aligned with the third positive pressure plate 4321 to stick the plastic film 91 on the waste take-up roller 41 to the plastic film 91 on the plastic film roll 9, preventing the cut plastic film 91 from breaking. Here, breaking refers to the plastic film 91 on the side of the cutter 3613 near the feeding area breaking, which facilitates the waste take-up roller 41 to take up the waste. The first positive pressure plate 36121 can move up and down relative to the second positive pressure plate 36122.

[0074] After the cutting blade 3613 finishes cutting the hot-pressed parts of the top positive pressure plate 3612 and the bottom positive pressure plate 432, the waste material needs to be wound up by the waste material winding roller 41 to prevent the first positive pressure plate 36121 and the third positive pressure plate 4321 from being hot-pressed together and then sealed to the next mattress 8.

[0075] To address the issue of the impact of the pressing of the first positive pressure plate 36121 and the third positive pressure plate 4321 on the waste material recovery by the waste material take-up roller 41, in this embodiment, as follows: Figure 12 , Figure 13 and Figure 15 As shown, a positioning seat 3614 is also provided in the second chamber 332, wherein a first positive pressure plate 36121 is fixed on the bottom wall of the positioning seat 3614, and a longitudinally arranged insertion groove 36141 is provided on the side wall of the positioning seat 3614. An insertion block 36131 is fixedly provided on the side wall cut to 3613 and inserted into the insertion groove 36141. The side wall of the insertion block 36131 is slidably connected to the side wall of the insertion groove 36141. A third spring 36142 is also provided in the insertion groove 36141. The bottom of the third spring 36142 is fixedly connected to the bottom wall of the insertion groove 36141, and the top of the third spring 36142 is fixedly connected to the bottom wall of the insertion block 36131.

[0076] like Figure 12 As shown, the third spring 36142 is a compression spring. Under normal conditions, the third spring 36142 pushes the top wall of the insertion block 36131 to abut against the top wall of the insertion groove 36141. When the push plate 35 drives the cutting plate 3613 and the second positive pressure plate 36122 to move downward, since the insertion block 36131 is inserted into the insertion groove 36141 and pushed by the third spring 36142, it can synchronously drive the positioning seat 3614 and the first positive pressure plate 36121 to move downward and cooperate with the third positive pressure plate 4321 on the bottom positive pressure plate 432 to heat press the plastic film 91.

[0077] The top wall of the positioning seat 3614 is fixedly installed with an armature 372, the bottom wall of the sealing cover 38 is provided with an electromagnet 371 adapted to the armature 372, the bottom wall of the third slot 34 is also installed with a touch button 7, and the base 1 is also installed with a delay module. The touch button 7, the electromagnet 371, the delay module and the second motor 42 are all electrically connected to the central control unit 100.

[0078] Specifically, such as Figure 16 As shown, the delay module is connected in series between the touch button 7 and the central control unit 100. The signal from the touch button 7 is delayed for a period of time by the delay module before being transmitted to the central control unit 100.

[0079] like Figure 16As shown, with the above settings, after the pressing seat 3 completes the compression of the mattress 8, the first hot pressing plate group 361 and the second hot pressing plate group 43 come into contact and heat-press the plastic film 91, as follows: Figure 12 As shown, at this time, the cutting blade 3613 cuts the plastic film 91 between the third positive pressure plate 4321 and the fourth positive pressure plate 4322. At this time, as... Figure 14 As shown, at this time, the push plate 35 presses the touch button 7 on the bottom wall of the third chamber 34. The touch button 7 sends an electrical signal to the delay module. After a delay, the signal is transmitted to the central control unit 100. After receiving the electrical signal, the central control unit 100 supplies power to the second motor 42 and the electromagnet 371. At this time, the electromagnet 371 is energized, changing the surrounding magnetic field, which in turn attracts the armature 372 to move upward and further compresses the third spring 36142. Figure 15 As shown, at this time, the positioning seat 3614 and the first positive pressure plate 36121 are moved upward, and the first positive pressure plate 36121 and the third positive pressure plate 4321 are disconnected. At this time, the second motor 42 drives the waste material winding roller 41 to wind up the cut plastic film 91, so that the part where the first positive pressure plate 36121 and the third positive pressure plate 4321 are pressed together is wound onto the waste material winding roller 41, preventing the heat-pressed part from being used for the sealing of the next mattress 8.

[0080] When the pressing seat 3 rises, the waste take-up roller 41 needs to take up the plastic film 91 on the plastic film roll 9, so that the plastic film roll 9 can be unloaded. In order to prevent the plastic film 91 from causing the waste take-up roller 41 to rotate in the opposite direction, in this embodiment, as follows: Figure 12 and Figure 13 As shown, the clamping groove 31 is also provided with a clamping mechanism for clamping and fixing the plastic film 91. When the pressing seat 3 is at the bottom and compressing the mattress 8 and hot pressing the plastic film 91, the clamping mechanism releases the clamping of the plastic film 91 inside the clamping groove 31. After the pressing seat 3 disengages from the base 1, the clamping mechanism begins to clamp the plastic film 91 inside the clamping groove 31, so that the mattress 8 pushes the plastic film 91, and the plastic film roll 9 is stably unloaded.

[0081] Specifically, such as Figure 12 and Figure 13As shown, the clamping mechanism includes a sliding groove 303 formed on the side wall of the pressing seat 3 and communicating with the clamping groove 31, and also includes a clamping opening 302, a clamping push block 305, a first spring 3055, a pushing inclined surface 3052, and a pushing column 24. The clamping opening 302 is provided on the side wall of the clamping groove 31, the sliding groove 303 is provided on the side wall of the pressing seat 3 near the feeding area, the clamping push block 305 is slidably installed in the sliding groove 303, the pushing column 24 is fixedly installed on the mounting base 2 and extends vertically upward, the pushing inclined surface 3052 is provided on the clamping push block 305 to abut against the pushing column 24, and the first spring 3055 is sleeved on the clamping push block 305. One end of the first spring 3055 is fixedly connected to the clamping push block 305, and the other end of the first spring 3055 is fixedly connected to the pressing seat 3.

[0082] Specifically, the first spring 3055 is a tension spring. When the first spring 3055 is in its original length state, such as... Figure 11 As shown, the end of the clamping push block 305 is inserted into the clamping port 302. The clamping push block 305 and the clamping port 302 are used to clamp the plastic film 91 inside the clamping groove 31. When the pressing seat 3 completes the compression of the mattress 8, as shown... Figure 12 and Figure 13 As shown, at this time, the push column 24 abuts against the push inclined surface 3052 and pushes the clamping push block 305 to move away from the clamping port 302 and stretches the first spring 3055. At this time, the clamping push block 305 releases the clamping port 302 from the plastic film 91.

[0083] Specifically, in this embodiment, such as Figure 13 As shown, the clamping push block 305 includes a clamping rod 3051, a clamping head 3053, and a limiting plate 3054. The clamping rod 3051 is slidably connected to the sliding groove 303. The clamping head 3053 is located on the side of the clamping rod 3051 near the clamping opening 302. When clamping the plastic film 91, the clamping head 3053 is inserted into the clamping opening 302, causing the plastic film 91 to bend, thereby strengthening the fixation of the plastic film 91. The limiting plate 3054 is located at the end of the clamping rod 3051 away from the clamping opening 302. A first spring 3055 is sleeved on the clamping rod 3051. One end of the first spring 3055 is fixed on the limiting plate 3054, and the other end is fixed on the side wall of the pressing seat 3.

[0084] Specifically, such as Figure 13 As shown, the clamping rod 3051 is provided with a push-up groove with a longitudinal section of parallelogram, wherein the push-up inclined surface 3052 is one of the inclined surfaces in the push-up groove, and the bottom wall of the pressing seat 3 is provided with an insertion hole 304 communicating with the sliding groove 303, wherein the insertion hole 304 is aligned with the push-up groove for the insertion of the push-up column 24.

[0085] With the above settings, when the lifting mechanism drives the pressing seat 3 to be above the mattress 8 and not in contact with the mattress 8, the push column 24 is located outside the push groove, and the clamping head 3053 cooperates with the clamping port 302 to clamp the plastic film 91. When the pressing seat 3 compresses the mattress 8, the push column 24 passes through the insertion hole 304 and enters the push groove and abuts against the push inclined surface 3052, thereby pushing the clamping rod 3051 to move away from the clamping port 302 and releasing the clamping of the plastic film 91.

[0086] The mattress packaging equipment handles the entire mattress packaging process as follows:

[0087] Let the initial situation be as follows: Figure 3 or Figure 9 As shown, at this time, the pressing seat 3 is at the top of the pressing area under the action of the hydraulic cylinder 6.

[0088] The central control unit 100 controls the first motor 102 to drive the first conveyor roller group 11 and the second conveyor roller group 12 to rotate synchronously, thereby moving the mattress 8 from the feeding area to the pressing area. At this time, the mattress 8 pushes the vertical plastic film 91 between the pressing seat 3 and the mounting seat 2 to extend towards the pressing area, which will drive the plastic film roll 9 to unload the material from the pressing area. Figure 9 Moved to Figure 11 The position sensor 105 detects that the mattress 8 has moved to the pressing position of the pressing area and transmits an electrical signal to the central control unit 100. This causes the central control unit 100 to send a stop drive signal to the first motor 102, stopping the mattress 8 at the pressing position of the pressing area. Then, the central control unit 100 controls the solenoid valve to change the flow direction of the hydraulic oil, causing the hydraulic rod of the hydraulic cylinder 6 to extend and push the pressing seat 3 downward. Figure 12 As shown, during this process, as the pressing seat 3 moves downward, the pressing seat 3 completes the compression of the mattress 8, and simultaneously, as... Figure 14 As shown, the first push rod 391 on the pressing seat 3 abuts against the extension plate 104 on the base 1, causing the first push rod 391 to rotate around the rotation axis 393, thereby driving the end of the second push rod 392 to push downward, thus pushing the push plate 35 to move downward. At this time, the push plate 35 pushes the first hot pressing plate group 361 to extend out of the C-shaped groove, and makes the first hot pressing plate group 361 cooperate with the second hot pressing plate group 43 on the base 1 to heat-press and seal the plastic film 91 on the side of the mattress 8. At the same time, the cutting blade 3613 on the first hot pressing plate group 361 is inserted into the cutting groove 433 between the third positive pressure plate 4321 and the fourth positive pressure plate 4322, as shown. Figure 12As shown, the plastic film 91 is cut at this time; simultaneously, the push post 24 on the mounting base 2 passes through the insertion hole 304 and extends into the push groove, abutting against the push slope 3052, thereby pushing the clamping rod 3051 to move away from the clamping opening 302 and stretching the first spring 3055. The clamping head 3053 releases the clamping opening 302 from the plastic film 91 in the clamping groove 31. When the pressing seat 3 completes the compression of the mattress 8, as shown... Figure 14 As shown, at this time, the push plate 35 presses the touch button 7. The touch button 7 transmits a signal to the delay module, which delays for a period of time before transmitting the signal to the central control unit 100. After receiving the signal from the delay module, the central control unit 100 energizes the electromagnet 371 and the second motor 42. After the electromagnet 371 is energized, it changes the surrounding magnetic field, such as... Figure 15 As shown, this attracts the armature 372 to move upward, which in turn drives the positioning seat 3614 and the first positive pressure plate 36121 to move upward and further compress the third spring 36142. At this time, the first positive pressure plate 36121 and the third positive pressure plate 4321 disengage, stopping the hot pressing of the plastic film 91. The second motor 42 drives the electric waste winding roller 41 to rotate, thereby winding up the plastic film 91 hot-pressed by the first positive pressure plate 36121 and the third positive pressure plate 4321, preventing the plastic film 91 here from being used for the hot pressing and sealing of the next mattress 8, which would affect the aesthetics of the mattress 8 sealing. After the second motor 42 drives for a period of time, the central control unit 100 provides an electrical signal to the solenoid valve, changing the position of the valve core and changing the flow direction of the hydraulic oil, thereby causing the hydraulic cylinder 6 to drive the pressing seat 3 to move upward. During this process, the push column 24 disengages from the push inclined surface 3052. When the first spring 3055 moves the clamping rod 3051 towards the clamping opening 302, the clamping head 3053 inserts into the clamping opening 302 to clamp the plastic film 91 in the clamping groove 31. As the pressing seat 3 moves upward, the pressing seat 3 drags the plastic film roll 9 to release the material. When the pressing seat 3 moves upward, the first push rod 391 gradually disengages from the extension frame plate 104. At this time, the second spring 342 pushes the push plate 35 upward, thereby retracting the first hot pressing plate group 361 into the C-shaped groove 33. At this time, the central control unit 100 continues to control the first motor 102 to rotate, thereby driving the first conveying roller group 11 and the second conveying roller group 12 to rotate. The second conveying roller group 12 outputs the sealed and compressed mattress 8 outward, and the first conveying roller group 11 continues to convey the next mattress 8 to be packaged to the pressing area, thereby realizing the continuous packaging of the mattress 8.

[0089] Specifically, in this embodiment, the hot-pressing time of the plastic film 91 can be set to ten seconds, the delay time of the delay module is five seconds, and the energizing time of the electromagnet 371 and the second motor 42 is defined as five seconds. It is worth noting that the five-second delay of the delay module mainly utilizes the cooperation of the first positive pressure plate 36121 and the third positive pressure plate 4321 to hot-press the plastic film 91, thereby connecting the plastic film 91 held by the clamping mechanism with the plastic film 91 on the plastic film roll 9, facilitating the unloading of the plastic film roll 9.

[0090] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
