Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a mattress compression and rolling device. Background Art

[0002] Mattress rolling and packaging is a modern technology used to facilitate the transportation and storage of mattresses. Through this technology, mattresses that were originally bulky and difficult to carry can be compressed, rolled up and packaged in a relatively small space, making them easier to store and transport, and providing consumers with a more convenient purchasing experience. In order to reduce the difficulty of rolling mattresses and improve the efficiency of mattress rolling processing, related technologies often use automated winding equipment to roll up the coated and compressed mattresses. For some larger mattresses, if they are directly rolled up by the winding equipment, the volume of the rolled mattress is still large. In order to further reduce the final volume of the mattress after rolling, related technologies will add folding equipment to the production line. The folding equipment is used to fold the mattress before rolling.

[0003] The patent document with authorization announcement number CN108423218B discloses a self-adjusting full-size mattress rolling machine, including a film covering machine, a transition waiting table, a compression packaging machine, a rotating table, a folding table and an automatic rolling machine. The film covering machine and the compression packaging machine are connected together through a transition waiting table. The right side of the compression packaging machine is connected to the rotating table, and the other side of the rotating table is connected to the folding table. The right side of the folding table is connected to the automatic rolling machine. The folding table includes a folding frame body, a folding table roller, a folding and pressing mechanism, a folding mechanism, a hot material mechanism and a patting mechanism. A folding table roller is provided at the center of the folding frame body, a folding and pressing mechanism is provided above the folding table roller, a vertical folding mechanism and a patting mechanism are provided on the horizontal plane where the folding table roller is located, and a hot material mechanism is provided above the folding table roller on the right side of the folding frame body. When the mattress needs to be folded, the mattress is centered in the middle of the folding table, and the folding mechanism automatically folds the mattress in half. While the mattress is transported to the next workstation, the ironing mechanism irons the folded mattress flat.

[0004] The self-adjusting, full-size mattress rolling machine described in the aforementioned patent document utilizes two separate steps for mattress folding and rolling. These steps require separate operations, increasing production time and reducing efficiency. Furthermore, the mattress folding process requires high precision in positioning and operation.

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 10 As shown, the mattress compression and packaging device of the present invention includes a frame body 1 and a conveying mechanism, a folding mechanism, and a winding mechanism disposed on the frame body 1. The conveying mechanism is used to convey a mattress 12 to be packaged onto the frame body 1 and position the mattress 12 opposite the folding mechanism and the winding mechanism. The conveying mechanism includes a plurality of conveying rollers 11, each of which is spaced apart along the length of the frame body 1. Both ends of each conveying roller 11 are rotatably connected to the frame body 1, and each conveying roller 11 is connected via a transmission structure. Any conveying roller 11 is connected to a motor, which is mounted on the frame body 1 and drives the conveying roller 11 connected thereto to rotate. The other conveying rollers 11 rotate synchronously via a transmission structure, wherein the transmission structure includes but is not limited to a rack and pinion drive and a belt drive. The folding mechanism is used to fold the mattress 12, and the winding mechanism is used to wind up the folded mattress 12.

[0041] like Figure 1 、 Figure 4 and Figure 7As shown, the folding mechanism includes a driving member 2, a movable arm 21 and a lifting roller 22. The driving member 2 is installed on the frame body 1. The driving member 2 can be a motor. There are two movable arms 21. The two movable arms 21 are respectively located on both sides of the length of the conveying roller 11. The two movable arms 21 are fixedly connected by a connecting seat 26. The connecting seat 26 is "U"-shaped and is located on the lower side of the conveying roller 11. The driving end of the driving member 2 is fixed to a movable arm 21. When the driving member 2 is working, it drives the two movable arms 21 to rotate at the same time. The lifting roller 22 is a cylinder. The two ends of the lifting roller 22 are respectively connected to the two movable arms 21.

[0042] The lifting roller 22 is connected to the two movable arms 21 through two sets of moving components. The moving components include a driving member 3 23, a screw 24 and a guide block 25. The screw 24 is parallel to the movable arm 21. The driving member 3 23 is installed on the connecting seat 26. The driving member 3 23 can be a motor. The driving end of the driving member 3 23 is fixed to one end of the screw 24. When the driving member 3 23 is working, it drives the screw 24 to rotate around its own axis. The movable arm 21 is provided with a guide groove 211 in its length direction. The guide block 25 is slidably assembled in the guide groove 211, and the guide groove 211 is threadedly connected to the screw 24. When the screw 24 rotates, it drives the guide block 25 to slide in the guide groove 211. The lifting roller 22 slides along the length direction of the movable arm 21. The lifting roller 22 is rotationally connected to the guide block 25. In the process of using two sets of moving components to drive the lifting roller 22 to slide relative to the movable arm 21, it is necessary to ensure that the driving members 3 23 in the two sets of moving components work synchronously.

[0043] In other embodiments, only one moving assembly may be provided, with one moving assembly provided on one movable arm 21 and a guide assembly provided on the other movable arm 21. The moving assembly includes a driving member 3 23, a screw 24 and a guide block 25. The screw 24 is parallel to the movable arm 21. The driving member 3 23 is mounted on the connecting seat 26. The driving member 3 23 may be a motor. The driving end of the driving member 3 23 is fixed to one end of the screw 24. When the driving member 3 23 is working, it drives the screw 24 to rotate around its own axis. The movable arm 21 is provided with a guide groove 211 in its length direction. The guide block 25 is slidably assembled in the guide groove 211, and the guide groove 211 is threadedly connected to the screw 24. When the screw 24 rotates, it drives the guide block 25 to slide in the guide groove 211. The lifting roller 22 slides along the length direction of the movable arm 21. The lifting roller 22 is rotatably connected to the guide block 25.

[0044] The guide assembly includes a guide rod and a guide slider. The guide rod is fixed relative to the movable arm 21 and arranged parallel to the movable arm 21. The guide slider is slidably connected to the guide rod, and the guide slider is slidably connected to the guide groove 211 on the movable arm 21. One end of the lifting roller 22 is rotatably connected to the guide slider. When the moving assembly drives the lifting roller 22 to slide along the guide groove 211 on one movable arm 21, the guide assembly guides the sliding of the lifting roller 22 relative to the other movable arm 21.

[0045] The winding mechanism includes a drive structure and two sets of clamping assemblies. The two sets of clamping assemblies are respectively arranged at the two ends of the length of the conveying roller 11. The clamping assemblies include a clamping member 1 3 and a clamping member 2 31. The clamping member 1 3 is rotatably connected to the frame body 1 along its length. Specifically, a connecting shaft can be fixed to the frame body 1, and one end of the clamping member is rotatably assembled with the connecting shaft. The clamping member 1 3 and the clamping member 2 31 are connected by an elastic telescopic structure 33, and the clamping member 2 31 rotates around its end adjacent to the clamping member 1 3. In the initial state, the lifting roller 22 is located on the lower side of the two clamping members 2 31. When the driving member 1 2 drives the movable arm 21 to rotate, the lifting roller 22 pushes the two clamping members 2 31 to flip upward and pushes the mattress 12 to fold. That is, the folding mechanism cooperates with the clamping assembly to fold the mattress 12. The clamping assembly clamps the end of the mattress 12 after folding. The two sets of moving components then work synchronously, with the lifting roller 22 rolling the folded mattress 12 to increase the flatness of the folded mattress 12. The drive structure is connected to a set of clamping components. After the lifting roller 22 has completed rolling the mattress 12, the drive structure drives the clamping components connected to it to rotate, thereby rewinding the mattress 12.

[0046] like Figure 9 and Figure 10 As shown, the elastic telescopic structure 33 includes a first connector 331 and a second connector 332. The first connector 331 is hingedly connected to the first clamping member 3, while the second connector 332 is hingedly connected to the second clamping member 31. The first connector 331 and the second connector 332 are slidably assembled and elastically connected. The first connector 331 and the second connector 332 may be connected by a spring. When the lifting roller 22 pushes the two second clamping members 31 to rotate and fold the mattress 12, the elastic telescopic structure 33 is located at the folded portion of the mattress 12, and the elastic telescopic structure 33 is adapted to the thickness of the folded portion of the mattress 12.

[0047] The driving structure includes a driving member 2 37, a connecting shaft 36, a connecting rod 1 34 and a connecting rod 2 35. The connecting rod 1 34 is hinged to the clamping member 1 3, the connecting rod 2 35 is hinged to the clamping member 2 31, the connecting rod 1 34 and the connecting rod 2 35 are hinged, and the hinged ends of the connecting rod 1 34 and the connecting rod 2 35 are slidingly connected to the connecting shaft 36 along the length direction of the connecting shaft 36. The driving end of the driving member 2 37 is fixed to one end of the connecting shaft 36. The driving member 2 37 is used to drive the connecting shaft 36 to rotate. The driving member 2 37 can be a motor. In order to ensure the stability of the mattress 12 during the folding process and prevent the mattress 12 from moving relative to the frame body 1 during the folding process, a stopper (not shown in the figure) can also be provided on the frame body 1, and the stopper is connected to the frame body 1 for lifting. Specifically, the stopper can be connected to the frame body 1 through a cylinder, one end of the cylinder is fixed to the frame body, and the protruding end of the cylinder is fixed to the stopper. After the mattress 12 is transported to the designated position, in order to prevent the mattress 12 from deflecting during the folding process, the cylinder is started to make the stopper rise to the upper side of the conveying roller 11 and abut against the end of the mattress 12, so that the mattress 12 maintains the stability of its relative position to the frame body 1 during the folding process.

[0048] After the mattress 12 is folded, the connecting shaft 36 rotates to a horizontal state, the driving member 2 37 is started and drives the clamping member 1 3 and the clamping member 2 31 to rotate in the horizontal direction through the connecting shaft 36, the connecting rod 1 34, and the connecting rod 2 35. The clamping member 1 3 and the clamping member 2 31 clamp the mattress 12 and roll it up while rotating.

[0049] To further ensure the stability of the second driver 37 during operation, the second driver 37 is connected to the frame body 1 via a limiting assembly. The limiting assembly includes a limiting plate 38, a limiting block 39, and a third driver 23. The limiting plate 38 is fixed to the second driver 37. The third driver 23 is mounted on the frame body 1 and is used to drive the limiting block 39 to move vertically. The limiting block 39 has a limiting slot defined therein, and the limiting plate 38 engages with the limiting slot after rotating to a vertical position. The third driver 23 can be a cylinder, and the extended end of the third driver 23 is connected to the limiting block 39. When the third driver 23 is in operation, it drives the limiting block 39 to move vertically. In other embodiments, the driving member three 23 can also be a motor. When the driving member three 23 is a motor, the driving member is connected to the limit block 39 through a screw, and the limit block 39 is threadedly connected to the screw. The limit block 39 is also slidably connected to a slide rod, and the slide rod is fixed to the frame body 1 and parallel to the screw. When the driving member three 23 drives the screw to rotate, it can drive the limit block 39 to slide vertically.

[0050] To enhance the stability of the clamping assembly's grip on the folded mattress 12 and ensure smooth retraction of the mattress 12, the clamping assembly is further connected via a blocking structure. This blocking structure prevents the second clamping member 31 from moving away from the first clamping member 3 due to deformation of the mattress 12 when the clamping assembly is gripping the mattress 12. The blocking structure comprises a blocking block 32 and a clamping portion 311. The blocking block 32 is slidably connected to the first clamping member 3 along the width of the first clamping member 3. The blocking block 32 is in the form of an elongated block and is elastically connected to the first clamping member 3. A plurality of blocking bars are spaced apart on the blocking block 32. The clamping portion 311 is fixed to the second clamping member 31. The clamping portion 311 is provided with a protruding bar that opposes the drag rod and the blocking bar. Both the protruding bar and the blocking bar have an oblique tooth shape and unidirectionally slide with the blocking bar. When the second clamping member 31 approaches the first clamping member 3 to clamp the mattress 12 , the clamping portion 311 slides relative to the blocking block 32 , and the one-way sliding fit between the blocking strip and the convex strip restricts the clamping portion 311 from separating from the blocking block 32 .

[0051] To prevent the mattress 12 from being affected by simultaneous clamping at both ends during winding, and to reset the clamping assembly after the mattress 12 is fully wound, a blocking block 32 is connected to the clamping member 1 3 via a cylinder. The extended end of the cylinder is elastically connected to the blocking block 32. Before the drive mechanism begins to wind the mattress 12, the blocking mechanism on the clamping assembly not connected to the drive mechanism is released. Specifically, the blocking block 32 is pulled away from the engaging portion 311 by controlling the extension and contraction of the cylinder, thereby reducing the clamping force of the clamping assembly. After the mattress 12 is fully wound, the folding mechanism is reactivated, causing the movable assembly on the folding mechanism to slide the lifting roller 22, pushing the mattress 12 out of the clamping assembly.

[0052] To further facilitate the return of the clamping assembly to its initial state, annular magnetic members 221 are fixed to each end of the lifting roller 22. Electromagnets 312 are embedded in the two second clamping members 31, and the magnetic members 221 and electromagnets 312 are magnetically connected. After the mattress 12 is unloaded, the electromagnets 312 on the two second clamping members 31 are energized, magnetically securing the second clamping members 31 and the lifting roller 22. The driver 1 then drives the movable arm 21 to rotate and reset, and the second clamping members 31 rotate synchronously with the movable arm 21 to reset.

[0053] The overall working process of the mattress compression and rolling device of the present invention is as follows: like Figures 1 to 3 As shown, the mattress 12 to be rolled after compression is first placed on the conveyor roller 11 of the conveyor mechanism, and the mattress 12 is conveyed along the length direction of the frame body 1 to the relative position of the folding mechanism and the winding mechanism. The driving member 12 of the folding mechanism is in the start-up state. In the initial state, the lifting roller 22 is located below the two clamping members 2 31. When the movable arm 21 rotates, the lifting roller 22 moves upward, pushing the two clamping members 2 31 to flip upward, and at the same time pushing the mattress 12 to fold. Figures 4 to 6 As shown, at this time, the elastic telescopic structure 33 is at the folding part of the mattress 12, and its elastic connection characteristics can adapt to the thickness of the folding part of the mattress 12 to ensure the smooth folding action. After the folding is completed, the clamping assembly clamps the end of the mattress 12 after folding, preparing for the subsequent rolling action.

[0054] Afterwards, the two groups of moving components work synchronously, lifting the roller 22 to fit the folded mattress 12 and rolling the mattress 12, as shown in FIG. Figures 7 to 9 As shown, the lifting roller 22 is driven by the moving assembly to roll along the surface of the folded mattress 12, thereby increasing the flatness of the folded mattress 12 and making the mattress 12 smoother during the subsequent rolling process.

[0055] Finally, driver 2 37 is activated, its driving end rotating connecting shaft 36. This, through the articulated connection of connecting rod 1 34 and connecting rod 2 35, drives clamp 1 3 and clamp 2 31 to rotate horizontally. Clamp 1 3 and clamp 2 31 grip one end of mattress 12 and rotate, thereby reeling mattress 12. During the reeling process, driver 3 23 of the limiter assembly controls the vertical movement of the limiter block 39 as needed to ensure the stability of driver 2 37 and smooth reeling.

[0056] After the mattress 12 is rolled up, the control cylinder's expansion and contraction pulls the blocking block 32 away from the engaging portion 311, releasing the blocking structure's positional restrictions on clamping element 1 3 and clamping element 2 31. The folding mechanism is activated again, and the movable assembly drives the lifting roller 22 to slide, pushing the mattress 12 out of the clamping assembly. After the mattress 12 is unloaded, the control electromagnet 312 is energized, magnetically securing clamping element 2 31 and lifting roller 22 relative to each other. Drive element 1 2 drives movable arm 21 to rotate and reset, and clamping element 2 31 rotates and resets synchronously with movable arm 21, returning to its initial state and preparing for the next mattress 12 roll-up process.
