Description

Technical Field

[0001] The utility model relates to the technical field of mattress packaging, and particularly relates to a mattress folding device. Background Art

[0002] Mattress folding devices generally include a material pressing mechanism and a folding mechanism. After the material pressing mechanism tightly presses the midline of the mattress, the folding mechanism bends one side of the mattress relative to the other side to achieve the folding of the mattress. Cooperating with a wrapping machine, the folded mattress can be wrapped into a strip-shaped cylinder to reduce the packaging volume and transportation volume of the mattress.

[0003] In the related art, after the folding mechanism of the mattress folding device folds the mattress, due to the loose folding of the mattress, the two sides of the folded mattress are likely to relatively flip and form a certain unfolding angle, that is, the folding effect of the mattress is not good, which is likely to affect the conveying and wrapping operations of the mattress. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a mattress folding device, which is beneficial to improving the folding effect of the mattress.

[0005] According to an embodiment of the utility model, the mattress folding device includes: a material supporting frame having a conveying surface for supporting the mattress; a folding assembly including a rotary driver, a folding rod, a displacement driver and a pressing block. The rotary driver is in transmission connection with the folding rod to drive the folding rod to flip relative to the material supporting frame. The displacement driver is connected to the folding rod, and the displacement driver is in transmission connection with the pressing block to drive the pressing block to move away from or close to the folding rod. Wherein, the mattress folding device is configured to have a contracted state and a folded state. The contracted state is that the rotary driver drives the folding rod to flip downwards below the conveying surface, and the displacement driver drives the pressing block to approach the folding rod. The folded state is that the rotary driver drives the folding rod to flip upwards, jack up one side of the mattress and bend it towards the other side to complete the folding, and the displacement driver drives the pressing block to move away from the folding rod, so that the pressing block applies pressure to the folding edge of the mattress.

[0006] The mattress folding device according to the embodiments of the present utility model has at least the following beneficial effects: The material supporting frame has a conveying surface for supporting the mattress. Under the conveying action of the conveying surface, the conveying of the mattress can be realized. The mattress folding device is configured to have a contracted state and a folded state. The contracted state is that the displacement driver drives the pressing block close to the folding rod to avoid the problem that the pressing block hinders the rotation of the folding rod. The rotation driver drives the folding rod to rotate forward to the lower side of the conveying surface, which is beneficial to avoid the problem that the folding rod hinders the conveying of the mattress. Under the conveying action of the conveying surface, the mattress can be conveyed above the folding rod. The folded state is that the rotation driver is in transmission connection with the folding rod to drive the folding rod to rotate reversely, so that at least part of the folding rod rotates above the conveying surface. The folding rod abuts against the lower end of one side of the mattress, so that one side of the mattress is lifted and bent towards the other side to realize the preliminary folding of the mattress. The displacement driver can be flipped above the folding edge of the mattress. The displacement driver drives the pressing block away from the folding rod, so that the pressing block applies pressure to the folding edge of the mattress, so that the two sides of the mattress are closer at the folding edge, which is beneficial to reduce the angle of the two sides of the mattress flipping and unfolding after the pressure of the folding assembly on the mattress is eliminated, so as to reduce the occupied space of the mattress in the height direction, that is, improve the folding effect of the mattress, so as to facilitate the subsequent conveying and wrapping operations of the mattress, and avoid the problems of conveying deviation or wrapping failure caused by the collision between the mattress and the input port of the external conveying mechanism or wrapping machine.

[0007] According to some embodiments of the present utility model, the folding rod includes a first sub-rod, a second sub-rod and a third sub-rod. One end of the first sub-rod is connected to the rotation driver, and the other end of the first sub-rod is connected to one end of the second sub-rod. The second sub-rod is arranged at an angle with the first sub-rod. The displacement driver is connected to the second sub-rod. The pressing block is configured to be able to move away from or close to the second sub-rod. In the folded state, the second sub-rod is configured to be able to flip above the folding edge; the other end of the second sub-rod is connected to the third sub-rod. The third sub-rod is arranged at an angle with the second sub-rod. The third sub-rod extends in a direction away from the rotation driver.

[0008] Specifically, the folding rod includes a first sub-rod, a second sub-rod, and a third sub-rod. One end of the first sub-rod is connected to the rotary drive, and the other end of the first sub-rod is connected to one end of the second sub-rod. The second sub-rod is arranged at an angle with the first sub-rod. The other end of the second sub-rod is connected to the third sub-rod, and the third sub-rod extends away from the rotary drive, that is, the second sub-rod is located between the first sub-rod and the third sub-rod. In the folded state, the rotary drive drives the first sub-rod to rotate, thereby driving the second sub-rod and the third sub-rod to rotate synchronously. At this time, the third sub-rod at the end far from the rotary drive first abuts against the mattress, so that the mattress is bent. When one side of the mattress is initially folded relative to the other side, the angle formed by the first sub-rod and the second sub-rod corresponds to the folded edge of the mattress, which is beneficial to controlling the folding position of the mattress. The second sub-rod is configured to be able to flip above the folded edge of the mattress. The displacement drive is connected to the second sub-rod, and the pressing block is configured to be able to move closer to or away from the second sub-rod. When the displacement drive drives the pressing block to move away from the second sub-rod, the pressing block can apply pressure to the folded edge of the mattress, so that the two sides of the mattress are closer at the folded edge, which is beneficial to suppressing the angle of flipping and unfolding of the two sides of the mattress after the pressure of the flipping assembly is eliminated.

[0009] According to some embodiments of the present invention, the displacement drive includes a fixed end and a movable end that can relatively expand and contract. The fixed end is connected to the second sub-rod, and the movable end is connected to the pressing block. The pressing block is configured to be able to reciprocate along the length direction of the first sub-rod.

[0010] The displacement drive includes a fixed end and a movable end that can relatively expand and contract. The fixed end is connected to the second sub-rod, and the movable end is connected to the pressing block. Under the driving action of the displacement drive, the movable end and the fixed end can relatively expand and contract. Under the driving action of the displacement drive, the pressing block is configured to be able to reciprocate along the length direction of the first sub-rod. In the folded state, the angle formed by the first sub-rod and the second sub-rod corresponds to the folded edge of the mattress, which is beneficial to controlling the folding position of the mattress. The displacement drive drives the pressing block to move away from the second sub-rod, and the pressing block can apply pressure to the folded edge of the mattress, so that the two sides of the mattress are closer at the folded edge, which is beneficial to suppressing the angle of flipping and unfolding of the two sides of the mattress after the pressure of the flipping assembly is eliminated.

[0011] According to some embodiments of the present invention, the folding assembly further includes a guide post and a guide sleeve. The guide sleeve is connected to the folding rod. The guide sleeve is provided with a guide hole. One end of the guide post is connected to the pressing block, and the other end of the guide post passes through the guide hole and is slidably connected to the guide sleeve.

[0012] To increase the stability of the displacement of the pressing block, the flipping assembly of the mattress folding device further includes a guide post and a guide sleeve. The guide sleeve is connected to the folding rod, and the guide sleeve is provided with a guide hole. One end of the guide post is connected to the pressing block so that the guide post moves synchronously with the pressing block. The other end of the guide post passes through the guide hole of the guide sleeve and is slidably connected to the guide sleeve. Through the sliding connection between the guide post and the guide sleeve, the guiding function of the displacement of the pressing block can be realized, making the displacement of the pressing block more stable, so as to ensure that the pressing block can apply pressure to the folded edge of the mattress according to the preset position and stroke, improve the folding effect of the mattress, and inhibit the flipping and unfolding angles of both sides of the mattress after the pressure of the folding assembly is eliminated.

[0013] According to some embodiments of the present invention, the second sub-rod is provided with a through hole, the displacement driver passes through the through hole and is connected to the pressing block, and the guide post passes through the through hole and is connected to the guide sleeve.

[0014] Specifically, the second sub-rod is provided with a through hole, the displacement driver passes through the through hole and is connected to the pressing block, that is, the displacement driver and the pressing block are respectively located on both sides of the through hole. In the contracted state, the pressing block can be closer to the second sub-rod, which is beneficial to avoiding the problem that the setting of the pressing block hinders the rotation of the folding rod. The guide post passes through the through hole and is connected to the guide sleeve. While ensuring the sliding connection between the guide post and the guide sleeve, the restriction of the second sub-rod on the movement of the guide post can be eliminated.

[0015] According to some embodiments of the present invention, the wall surface of the first sub-rod adjacent to the second sub-rod is provided with a receiving groove, and the pressing block is partially arranged in the receiving groove.

[0016] The wall surface of the first sub-rod adjacent to the second sub-rod is provided with a receiving groove, and the pressing block is partially arranged in the receiving groove. The setting of the receiving groove can increase the setting length of the pressing block. The receiving groove can be used for the displacement driver to drive the pressing block to move reciprocally, which is beneficial to increasing the contact area between the pressing block and the mattress. In the folded state, it can ensure that the pressing block can apply pressure to the folded edge of the mattress, which is beneficial to improving the folding effect of the mattress.

[0017] According to some embodiments of the present invention, the included angle between the second sub-rod and the first sub-rod is less than 90°, and the included angle between the third sub-rod and the second sub-rod is greater than or equal to 90°; and / or,

[0018] A roller is rotatably connected to the connection part between the third sub-rod and the second sub-rod.

[0019] Optionally, the included angle between the second sub-rod and the first sub-rod is less than 90°, while the included angle between the third sub-rod and the second sub-rod is greater than 90°. In the folded state, the rotary drive drives the first sub-rod to rotate, thereby driving the second sub-rod and the third sub-rod to rotate synchronously. At this time, the third sub-rod at the end far from the rotary drive first abuts against the mattress and drives the mattress to bend and fold. When one side of the mattress is initially folded relative to the other side, the included angle formed by the first sub-rod and the second sub-rod corresponds to the folding edge of the mattress, thereby controlling the folding position of the mattress. The second sub-rod can be flipped above the folding edge of the mattress. The displacement drive is connected to the second sub-rod, and the pressing block can move closer to or away from the second sub-rod. When the displacement drive drives the pressing block to move away from the second sub-rod, the pressing block can apply pressure to the folding edge of the mattress. The included angle between the second sub-rod and the first sub-rod is less than 90°, so that the pressing block applies pressure to the folding edge from the opening side of the mattress towards the folding edge of the mattress, which is beneficial to improving the folding effect of the mattress, making the two sides of the mattress closer at the folding edge, and is beneficial to suppressing the angle of flipping and unfolding of the two sides of the mattress after the pressure of the flipping assembly is eliminated; Optionally, a roller is rotatably connected to the connection between the third sub-rod and the second sub-rod. In the folded state of the mattress folding device, under the driving action of the rotary drive, as the third sub-rod flips, the third sub-rod first abuts against the mattress and then separates from the mattress. The roller can be in rolling connection with the mattress to drive the mattress to further bend to complete the folding, and is beneficial to reducing the lateral displacement of the mattress caused by the flipping of the folding assembly.

[0020] According to some embodiments of the present invention, the folding assembly further includes a connecting shaft. The folding rod, the pressing block, and the displacement drive together form a folding member. A plurality of folding members are provided, and the plurality of folding members are arranged at intervals along the length direction of the connecting shaft and are all connected to the connecting shaft. The rotary drive is in transmission connection with the connecting shaft.

[0021] Specifically, the folding rod, the pressing block, and the displacement drive together form a folding member. A plurality of folding members are provided, and the plurality of folding members are arranged at intervals along the length direction of the connecting shaft and are all connected to the connecting shaft. The rotary drive is in transmission connection with the connecting shaft to drive the connecting shaft to rotate forward or backward, thereby driving the plurality of flipping members to flip synchronously. The folding assembly folds the mattress at multiple locations simultaneously, which is beneficial to improving the success rate of folding the mattress. Moreover, the pressure exerted on the mattress main body and the folding edge of the mattress by the plurality of folding members is beneficial to improving the folding effect of the mattress, and is beneficial to reducing the angle of flipping and unfolding of the two sides of the mattress after the pressure of the folding assembly on the mattress is eliminated, so as to reduce the occupied space of the mattress in the height direction, that is, to improve the folding effect of the mattress, facilitating subsequent conveying and wrapping operations of the mattress, and avoiding problems such as conveying deviation or wrapping failure caused by the collision between the mattress and the input port of the external conveying mechanism or wrapping machine.

[0022] According to some embodiments of the present utility model, the present utility model further includes a pressing plate, a transfer mechanism, and at least two connecting components.

Specifically, the pressing plate is provided with at least two second connecting holes, and one end of the connecting seat is provided with a first connecting hole, and the first connecting hole is arranged opposite to the second connecting hole, and at least one of the first connecting hole and the second connecting hole is a horizontally arranged strip-shaped hole. The fastening member passes through the first connecting hole and the second connecting hole to fix the connecting seat and the pressing plate. By adjusting the position of the fastening member in the strip-shaped hole, the hole position deviation caused by assembly error or processing error can be compensated. The transfer mechanism is connected to the other end of the connecting seat, that is, through the connection of the connecting component, to realize the connection between the transfer mechanism and the pressing plate, which is beneficial to avoiding the problem of assembly failure caused by the pressing plate being stuck. The material supporting frame has a conveying surface for conveying the mattress. The pressing plate is located above the conveying surface and is arranged parallel to the conveying surface. Under the driving action of the transfer mechanism, the pressing plate is driven to approach or move away from the conveying surface relatively. When the pressing plate approaches the conveying surface relatively, the pressing plate can abut against the mattress on the conveying surface to realize the pressing of the mattress. Cooperating with the folding component, the folding of the mattress can be realized to reduce the packaging volume of the mattress. The flexible connection between the connecting component and the pressing plate of the mattress folding device is beneficial to reducing the assembly difficulty of the pressing plate, so as to facilitate the assembly of the pressing plate and the transfer mechanism.

[0024] According to some embodiments of the present utility model, second connecting holes are provided at both ends of the pressing plate along its length direction, and the length direction of the strip-shaped hole is consistent with the length direction of the pressing plate; and / or,

[0025] The pressing plate includes a plate body and connecting blocks. Connecting blocks are respectively connected to both ends of the plate body. The connecting blocks are provided with second connecting holes. The fastening member includes a connecting column and a limiting ring. The connecting column passes through the first connecting hole and the second connecting hole and is fixedly connected to the limiting ring.

[0026] Optionally, both ends of the pressing plate along its length direction are provided with second connection holes. The length direction of the strip-shaped hole is consistent with the length direction of the pressing plate, that is, the length direction of the strip-shaped hole is adapted to the length direction of the pressing plate. At least one of the first connection hole and the second connection hole is a strip-shaped hole to ensure that the first connection hole can be opposite and communicate with the second connection hole. After the fastener passes through the first connection hole and the second connection hole, the connecting seat and the pressing plate can be fixedly connected, that is, through the connection of the connecting component, the connection between the transfer mechanism and the pressing plate is realized, which is beneficial to avoiding the problem that the pressing plate is stuck due to the processing error in the length direction and the assembly fails. Optionally, the pressing plate includes a plate body and a connecting block. Connecting blocks are respectively connected to both ends of the plate body. The second connection hole is arranged on the connecting block. Through the connection between the connecting block and the plate body, it is beneficial to reduce the inconvenience of processing hole positions on the plate body, so as to facilitate the connection of plate bodies of different specifications or types with the connecting component. The fastener includes a connecting column and a limiting ring.

[0052] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0053] Reference Figures 1 to 11 As shown, a mattress folding device according to an embodiment of the present invention comprises: a support frame 100 and a folding assembly 200. The mattress folding device is used to fold a mattress with good flexibility and durability, such as a cotton mattress, a latex mattress, etc.

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, the support frame 100 has a conveying surface 110 for supporting a mattress. The folding assembly 200 includes a rotary driver 220, a folding rod 210, a displacement driver 230 and a pressing block 240. The rotary driver 220 is located below the conveying surface 110 and is in transmission connection with the folding rod 210 to drive the folding rod 210 to flip relative to the support frame 100. The displacement driver 230 is connected to the folding rod 210, and the displacement driver 230 is in transmission connection with the pressing block 240 to drive the pressing block 240 to move away from or close to the folding rod 210.

[0055] Reference Figure 1 , Figure 2 and Figure 3As shown, the mattress folding device is configured to have a contracted state and a folded state. In the contracted state, the rotary driver 220 drives the folding rod 210 to flip downward to below the conveying surface 110, and the displacement driver 230 drives the pressing block 240 to approach the folding rod 210; in the folding state, the rotary driver 220 drives the folding rod 210 to flip upward, lift up one side of the mattress and bend it toward the other side to complete the folding, and the displacement driver 230 drives the pressing block 240 away from the folding rod 210, so that the pressing block 240 applies pressure to the folded edge 800 of the mattress.

[0056] In the contracted state, the displacement driver 230 drives the pressing block 240 to approach the folding rod 210 to avoid the problem that the pressing block 240 hinders the rotation of the folding rod 210 and the problem that the pressing block 240 hinders the transportation of the mattress. The rotation driver 220 drives the folding rod 210 to flip forward to the bottom of the conveying surface 110, thereby avoiding the problem that the folding rod 210 hinders the transportation of the mattress. Under the conveying action of the conveying surface 110, the mattress can be transported to the top of the folding rod 210.

[0057] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the folded state, the rotary driver 220 is transmission-connected with the folding rod 210 to drive the folding rod 210 to reversely flip, so that the folding rod 210 is at least partially flipped to above the conveying surface 110, and the folding rod 210 abuts against the lower end of one side of the mattress, so that one side of the mattress is lifted and bent toward the other side, so as to achieve the preliminary folding of the mattress, and the displacement driver 230 can flip to above the folding edge 800 of the mattress, and the displacement driver 230 drives the pressing block 240 away from the folding rod 210, so that the pressing block 240 applies pressure to the folding edge 800 of the mattress, so that the two sides of the mattress are more tightly attached at the folding edge 800, which is conducive to reducing the angle at which the two sides of the mattress are flipped and unfolded after the pressure of the folding assembly 200 on the mattress is eliminated, so as to reduce the space occupied by the mattress in the height direction, that is, to improve the folding effect of the mattress, so as to facilitate the subsequent conveying and rolling operations of the mattress, and avoid the collision of the mattress with the external conveying mechanism or the input port of the rolling machine, resulting in conveying deviation or rolling failure.

[0058] It should be noted that the rotary driver 220 may be a forward and reverse motor. After one side of the mattress is folded relative to the other side, the folded mattress has an open side and a closed side, the closed side forms a fold, and the closed side of the mattress is the folded edge 800 mentioned above.

[0059] Reference Figure 1 , Figure 4 and Figure 5As shown, it can be understood that specifically, the folding rod 210 includes a first sub-rod 211, a second sub-rod 212, and a third sub-rod 213. One end of the first sub-rod 211 is connected to the rotary driver 220, and the other end of the first sub-rod 211 is connected to one end of the second sub-rod 212. The second sub-rod 212 is arranged at an angle with the first sub-rod 211. The other end of the second sub-rod 212 is connected to the third sub-rod 213. The third sub-rod 213 is arranged at an angle with the second sub-rod 212, and the third sub-rod 213 extends in a direction away from the rotary driver 220. That is, the second sub-rod 212 is located between the first sub-rod 211 and the third sub-rod 213.

[0060] Referring to Figure 1 , Figure 4 and Figure 5 As shown, the displacement driver 230 is connected to the second sub-rod 212. Under the driving action of the displacement driver 230, the pressing block 240 is configured to be able to move away from or close to the second sub-rod 212. In the folded state, under the driving action of the rotary driver 220, the second sub-rod 212 is configured to be able to flip above the folded edge 800 of the mattress.

[0061] Referring to Figure 1 , Figure 4 and Figure 5 As shown, in the folded state, the rotary driver 220 drives the first sub-rod 211 to rotate, thereby driving the second sub-rod 212 and the third sub-rod 213 to rotate synchronously. At this time, the third sub-rod 213 at the end far from the rotary driver 220 first abuts against the mattress and drives the mattress to bend and fold. When one side of the mattress is initially folded relative to the other side, the angle formed by the first sub-rod 211 and the second sub-rod 212 corresponds to the folded edge 800 of the mattress, so as to control the folding position of the mattress, so that the folding position of the mattress can be controlled at the midline of the mattress. The second sub-rod 212 is configured to be able to flip above the folded edge 800 of the mattress. The displacement driver 230 is connected to the second sub-rod 212, and the pressing block 240 can move close to or away from the second sub-rod 212. When the displacement driver 230 drives the pressing block 240 to move away from the second sub-rod 212, the pressing block 240 can apply pressure to the folded edge 800 of the mattress, so that the two sides of the mattress are closer at the folded edge 800, which is beneficial to suppressing the flipping and unfolding angle of the two sides of the mattress after the pressure of the flipping assembly is eliminated.

[0062] Referring to Figure 1 , Figure 4 and Figure 5As shown, under the driving action of the rotary drive 220, the third sub-rod 213 first abuts against the lower end of the mattress. As the mattress is gradually bent, the contact area between the third sub-rod 213 and the mattress gradually decreases, and the second sub-rod 212 gradually abuts against the mattress. The included angle between the second sub-rod 212 and the first sub-rod 211 is arranged. Through the limiting action of the second sub-rod 212 and the first sub-rod 211 on the mattress, it is beneficial to control the position of the folded edge 800 formed after the mattress is bent, so that the folded edge 800 of the mattress overlaps with the midline of the mattress, so as to realize the folding of one side of the mattress relative to the other side.

[0063] Referring to Figure 1 、 Figure 5 and Figure 6 As shown, it can be understood that the displacement drive 230 includes a fixed end 231 and a movable end 232 that can relatively expand and contract. The fixed end 231 is connected to the second sub-rod 212, and the movable end 232 is connected to the pressing block 240. The pressing block 240 is configured to be able to reciprocate along the length direction of the first sub-rod 211.

[0064] Referring to Figure 1 、 Figure 5 and Figure 6 As shown, specifically, the displacement drive 230 can be a cylinder. The cylinder is connected to the second sub-rod 212, and the movable end 232 of the cylinder is connected to the pressing block 240. Under the driving action of the displacement drive 230, the pressing block 240 is configured to be able to drive the pressing block 240 to reciprocate along the length direction of the first sub-rod 211. In the folded state, the included angle formed by the first sub-rod 211 and the second sub-rod 212 corresponds to the folded edge 800 of the mattress, so as to control the formation position of the folded edge 800 of the mattress. The displacement drive 230 drives the pressing block 240 to move away from the second sub-rod 212, and the pressing block 240 can apply pressure to the folded edge 800 of the mattress, so that the two sides of the mattress are closer at the folded edge 800, which is beneficial to suppressing the angle of the two sides of the mattress from flipping and unfolding after the pressure of the flipping assembly is eliminated.

[0065] Referring to Figure 1 、 Figure 5 and Figure 6 As shown, it can be understood that in order to enhance the stability of the displacement of the pressing block 240, the folding assembly 200 further includes a guide post 251 and a guide sleeve 252. The guide sleeve 252 is connected to the folding rod 210. The guide sleeve 252 is provided with a guide hole. One end of the guide post 251 is connected to the pressing block 240, and the other end of the guide post 251 passes through the guide hole and is slidably connected to the guide sleeve 252.

[0066] Referring to Figure 1 、 Figure 5 and Figure 6As shown, the guide post 251 is connected to the surface of the pressure block 240 close to the second sub-rod 212, while the guide sleeve 252 is fixedly connected to the second sub-rod 212. One end of the guide post 251 is fixedly connected to the pressure block 240, and the other end of the guide post 251 passes through the guide hole and is slidably connected to the guide sleeve 252. Through the sliding connection between the guide post 251 and the guide sleeve 252, it is beneficial to realize the guiding function of the displacement of the pressure block 240, making the displacement of the pressure block 240 more stable, so as to ensure that the pressure block 240 can apply pressure to the folded edge 800 of the mattress according to the preset position and stroke, so as to improve the folding effect of the mattress and inhibit the flipping and unfolding angles of both sides of the mattress after the pressure of the folding assembly 200 is eliminated.

[0067] It should be noted that the mattress folding device controls the stroke of the cylinder to realize the stroke control of the pressure block 240, which is beneficial to avoid the problem of the guide post 251 coming out of the guide hole.

[0068] Refer to Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that the second sub-rod 212 is provided with a through hole 2121, the displacement driver 230 passes through the through hole 2121 and is connected to the pressure block 240, and the guide post 251 passes through the through hole 2121 and is connected to the guide sleeve 252.

[0069] Refer to Figure 1 、 Figure 4 and Figure 5 As shown, specifically, in the folded state, the second sub-rod 212 has a first plane facing the mattress, and the second sub-rod 212 has a second plane facing away from the first plane. The fixed end 231 of the displacement driver 230 is connected to the second plane, and the movable end 232 passes through the through hole 2121 and is connected to the pressure block 240, that is, the displacement driver 230 and the pressure block 240 are respectively located on both sides of the through hole 2121. In the contracted state, it can make the pressure block 240 closer to the second sub-rod 212, which is beneficial to avoid the problem that the setting of the pressure block 240 hinders the rotation of the folding rod 210. The guide post 251 passes through the through hole 2121 and is connected to the guide sleeve 252. While ensuring the sliding connection between the guide post 251 and the guide sleeve 252, it can eliminate the restriction of the second sub-rod 212 on the reciprocating movement of the guide post 251.

[0070] Refer to Figure 1 、 Figure 4 and Figure 5As shown, specifically, each pressing block 240 is provided corresponding to two sets of guide posts 251 and guide sleeves 252. One set of guide posts 251 and guide sleeves 252 is connected to one end of the pressing block 240 close to the first sub-bar 211, and the other set of guide posts 251 and guide sleeves 252 is connected to one end close to the third sub-bar 213. The mattress folding device is provided with multiple sets of guide posts 251 and guide sleeves 252, which is beneficial to enhancing the guiding effect on the displacement of the pressing block 240 and restricting the rotation of the pressing block 240, making the displacement of the pressing block 240 more reliable and stable.

[0071] Referring to Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that a receiving groove 2111 communicating with the through hole 2121 is provided on the wall surface of the first sub-bar 211 adjacent to the second sub-bar 212, and a part of the pressing block 240 is arranged in the receiving groove 2111.

[0072] Referring to Figure 1 、 Figure 4 and Figure 5 As shown, a part of the pressing block 240 is arranged in the receiving groove 2111. The setting of the receiving groove 2111 can increase the setting length of the pressing block 240. The receiving groove 2111 can be used for the displacement driver 230 to drive the pressing block 240 to move reciprocally, which is beneficial to eliminating the gap between the end face of the first sub-bar 211 close to the second sub-bar 212 and the pressing block 240, and is beneficial to eliminating the problem that the first sub-bar 211 blocks the displacement of the pressing block 240, and is beneficial to increasing the contact area between the pressing block 240 and the mattress. In the folded state of the mattress folding device, it is ensured that the pressing block 240 can apply pressure to the folded edge 800 of the mattress, which is beneficial to improving the folding effect of the mattress.

[0073] Referring to Figure 1 、 Figure 4 and Figure 5As shown, it can be understood that the included angle between the second sub-rod 212 and the first sub-rod 211 is less than 90°, while the included angle between the third sub-rod 213 and the second sub-rod 212 is greater than 90°. In the folded state, the rotation driver 220 drives the first sub-rod 211 to rotate, thereby driving the second sub-rod 212 and the third sub-rod 213 to rotate synchronously. At this time, the third sub-rod 213 at the end far from the rotation driver 220 first contacts the mattress and drives the mattress to bend and fold. When one side of the mattress is initially folded relative to the other side, the included angle formed by the first sub-rod 211 and the second sub-rod 212 corresponds to the folding edge 800 of the mattress, so as to control the formation position of the folding edge 800 of the mattress. The second sub-rod 212 can be flipped above the folding edge 800 of the mattress. The displacement driver 230 is connected to the second sub-rod 212, and the pressing block 240 can move closer to or away from the second sub-rod 212. When the displacement driver 230 drives the pressing block 240 to move away from the second sub-rod 212, the pressing block 240 can apply pressure to the folding edge 800 of the mattress. The included angle between the second sub-rod 212 and the first sub-rod 211 is less than 90°, so that the pressing block 240 applies pressure to the folding edge 800 of the mattress from the opening side of the mattress towards the folding edge 800, which is beneficial to improving the folding effect of the mattress, making the two sides of the mattress closer at the folding edge 800, and is beneficial to suppressing the flipping and unfolding angles of the two sides of the mattress after the pressure of the flipping assembly is eliminated.

[0074] Referring to Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that a roller 270 is rotatably connected to the connection between the third sub-rod 213 and the second sub-rod 212. In the folded state of the mattress folding device, under the driving action of the rotation driver 220, as the third sub-rod 213 flips, the third sub-rod 213 first contacts and then separates from the mattress. The roller 270 can be in rolling connection with the mattress, so that the contact position between the folding assembly 200 and the mattress is transferred from the third sub-rod 213 to the second sub-rod 212, so as to drive the mattress to further bend to complete the folding, and is beneficial to reducing the lateral displacement of the mattress caused by the flipping of the folding assembly 200.

[0075] Referring to Figure 1 、 Figure 3 and Figure 5 As shown, it can be understood that the folding assembly 200 further includes a connecting shaft 260. The folding rod 210, the pressing block 240 and the displacement driver 230 together form a folding member. A plurality of folding members are arranged at intervals along the length direction of the connecting shaft 260 and are all connected to the connecting shaft 260. The rotation driver 220 is in transmission connection with the connecting shaft 260.

[0076] Referring to Figure 1 、 Figure 3 and Figure 5As shown, the rotary driver 220 is transmission-connected with the connecting shaft 260 to drive the connecting shaft 260 to rotate forward or reverse, thereby driving the multiple flipping components to flip synchronously. The folding component 200 folds multiple locations of the mattress synchronously, which is beneficial to improving the success rate of folding the mattress. The pressure applied to the mattress body and the folding edge 800 of the mattress by the multiple folding components is beneficial to improving the folding effect of the mattress, and is beneficial to reducing the flipping and unfolding angles of the two sides of the mattress after the pressure of the folding component 200 on the mattress is eliminated, so as to reduce the space occupied by the mattress in the height direction, that is, to improve the folding effect of the mattress, so as to facilitate the subsequent transportation and rolling operations of the mattress, and avoid the collision between the mattress and the external conveying mechanism or the input port of the rolling machine, resulting in conveying deviation or rolling failure.

[0077] It is understandable that the mattress folding device further includes: a connecting assembly 300 , a pressing plate 700 and a transfer mechanism 600 .

By adjusting the position of the fastener 320 in the strip hole, it is beneficial to compensate for the hole position deviation caused by assembly error or processing error. The transfer mechanism 600 is connected to the other end of the connecting seat 310, that is, through the connection action of the connecting component 300, the connection between the transfer mechanism 600 and the pressure plate 700 is realized, which is beneficial to avoid the problem of assembly failure caused by the pressing plate 700 getting stuck.

The pressing plate 700 is located above the conveying surface 110 and is arranged parallel to the conveying surface 110. Driven by the transfer mechanism 600, the pressing plate 700 is driven to approach or move away from the conveying surface 110. When the pressing plate 700 approaches the conveying surface 110, the pressing plate 700 can abut against the mattress on the conveying surface 110 to achieve pressing of the mattress. Cooperating with the folding assembly 200, the mattress can be folded in half to reduce the packaging volume of the mattress. The mattress folding device is flexibly connected to the pressing plate 700 through the connecting assembly 300, which is beneficial to reducing the assembly difficulty of the pressing plate 700 and facilitating the assembly of the pressing plate 700 and the transfer mechanism 600.

The lifting member 610 is slidably connected to the guide rail 623. Through the sliding connection between the lifting member 610 and the guide rail 623, in cooperation with the connection between the belt 622 and the lifting member 610, the stability of the transverse movement of the lifting member 610 can be ensured.

[0104] Referring to Figure 1 , Figure 9 and Figure 10As shown, specifically, the slide rail, the lifting member 610, the belt 622, and at least two pulleys 621 together form a transfer member. Both ends of the pressing plate 700 are connected with the transfer member, and the transfer members at both ends are respectively connected with the connecting seats 310 at both ends. The transverse movement member 620 further includes a transmission shaft 624, and both ends of the transmission shaft 624 are respectively connected with the pulley 621 in the front and the pulley 621 in the rear. Taking the example that two groups of transfer members are arranged at intervals front and rear, the lifting member 610 in the front is slidably connected with the front guide rail 623, and the lifting member 610 in the rear is slidably connected with the rear guide rail 623. The driving motor 625 is connected with the transmission shaft 624 to drive the transmission shaft 624 to rotate, thereby driving the two pulleys 621 in the front and the rear to rotate synchronously, that is, driving the two lifting members 610 in the front and the rear to move transversely synchronously.

[0105] Referring to Figure 1 , Figure 7 and Figure 8 As shown, it can be understood that specifically, a roller shaft 500 is rotatably connected to the pressing plate 700, and the upper end of the roller shaft 500 is located above the upper end of the pressing plate 700. Under the driving action of the transfer mechanism 600, the pressing plate 700 is tightly pressed against the midline of the mattress. Cooperating with the folding assembly 200, half of the mattress can be folded relative to the other half along the midline, that is, the mattress is folded in half. At this time, the pressing plate 700 is clamped in the middle of the folded mattress. Under the driving action of the lifting member 610, the pressing plate 700 can be separated from the mattress below, and the upper end of the roller shaft 500 is located above the upper end of the pressing plate 700, and the roller shaft 500 abuts against the upper mattress. Through the rolling connection between the roller shaft 500 and the mattress, under the driving action of the transverse movement member 620, the pressing plate 700 can be withdrawn from the middle of the folded mattress. The setting of the roller shaft 500 is beneficial to reducing the lateral displacement of the mattress caused by the transverse movement of the pressing plate 700.

[0106] In the traditional material pressing assembly, after the mattress is folded in half, due to the elastic action of the mattress itself, both sides of the mattress will produce a certain flip and form a certain unfolding angle, resulting in a relatively large occupied space in the height direction of the folded mattress. Therefore, the traditional material pressing assembly has a relatively large stroke in the height direction, and generally needs to be provided with multi-stage driving in the height direction, with a high cost. And because the stroke in the height direction is relatively large, for the pneumatically driven cylinder, it is difficult to ensure the parallelism of both sides of the pressing plate 700, and it is easy to cause problems such as jamming of the pressing plate 700 or the transfer mechanism 600.

[0107] The mattress folding device provided by the embodiment of the present utility model can improve the folding effect of the mattress through the structural improvement of the folding component 200, so that the occupied space of the folded mattress in the height direction is smaller, thereby reducing the stroke set by the lifting component 610 of the mattress folding device in the height direction. Only one-stage drive can meet the stroke requirement, and the cost is relatively low. Moreover, for the pneumatic cylinder of pneumatic drive, the pneumatic stroke is shortened, which is beneficial to ensuring the parallelism on both sides of the pressing plate 700. With the connection structure between the connecting seat 310 and the pressing plate 700, the fastener 320 can move to a certain extent in the strip-shaped hole, thus avoiding the problem of jamming of the pressing plate 700 or the transfer mechanism 600.

[0108] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
