The flipping drive is used to drive the flipping bracket to rotate forward or backward; a transition assembly, with the front end connected to the lower conveying mechanism and the rear end connected to the rolling and wrapping mechanism. The transition assembly includes a transition belt, a first roller shaft and a second roller shaft. The transition belt is wound between the first roller shaft and the second roller shaft. Wherein, the mattress rolling and wrapping machine has a rolling and wrapping state, and the rolling and wrapping state is that both the first conveying surface and the second conveying surface are arranged at an angle with the transition belt.
[0006] The mattress wrapping machine according to the embodiments of the present invention has at least the following beneficial effects: The lower conveying mechanism is connected to the upper end of the lower frame and has a first conveying surface. The wrapping mechanism and the frame enclose a wrapping space. Under the action of the lower conveying mechanism, the mattress gradually penetrates into the wrapping space. Under the action of the wrapping mechanism, the wrapping operation of the mattress is realized.

That is, the transition component is arranged at the connection between the lower conveying mechanism and the wrapping mechanism, and the transition belt is wound between the first roller shaft and the second roller shaft. The mattress wrapping machine has a wrapping state, in which the second conveying surface flips and approaches relative to the first conveying surface, and both the first conveying surface and the second conveying surface are arranged at an angle to the transition belt. The setting of the transition component is beneficial to making the rotation angle of the first conveying surface relative to the second conveying surface smoother, so that the transition of the mattress between the lower conveying mechanism and the wrapping mechanism is smoother. The mattress can flip upward along the slope of the transition belt and the slope of the second conveying surface, so as to facilitate the wrapping of the mattress and improve the success rate of mattress wrapping, and is beneficial to avoiding the problem of wrapping failure caused by the mattress being folded in half.
[0007] According to some embodiments of the present invention, the lower conveying mechanism includes a first drive, a first belt, and a plurality of rotating shafts arranged front and rear. The first belt is wound between the front rotating shaft and the rear rotating shaft. The first drive is used to drive the rotating shaft to rotate. The first conveying surface is the upper surface of the first belt, and the rotating shaft located at the rear is the first roller shaft.
[0008] Specifically, the lower conveying mechanism includes a first drive and a plurality of rotating shafts arranged front and rear. Under the driving action of the first drive, the plurality of rotating shafts rotate. The first belt is wound between the front rotating shaft and the rear rotating shaft. The first conveying surface is the upper surface of the first belt. The setting of the first belt is beneficial to increasing the contact area between the lower conveying mechanism and the mattress. When the mattress is placed on the lower conveying mechanism, under the conveying action of the rotating shaft and the first belt, it is beneficial to convey the mattress from front to back. The rotating shaft located at the rear is the first roller shaft, that is, the transition component shares a rotating shaft with the lower conveying mechanism, so that the front end of the transition component is connected to the lower conveying mechanism, and the connection between the first belt and the transition belt is more compact. When the mattress is conveyed along the lower conveying mechanism to the transition component, following the rotation angle between the transition belt and the first conveying surface, it can assist in completing the upward flipping of the mattress, that is, assist in realizing the wrapping operation of the mattress, which is beneficial to improving the success rate of mattress wrapping.
[0009] According to some embodiments of the present invention, a plurality of first belts are provided, and the plurality of first belts are arranged at intervals left and right. A first distance is formed between the left and right adjacent first belts, and the front end of the transition belt is opposite to the first distance.
[0010] The lower conveying mechanism further includes a plurality of first belts arranged at intervals left and right. The first belts are wound between the front end rotating shaft and the rear end rotating shaft. Under the rotating action of the first belts, the mattress is conveyed from front to back. A first spacing is formed between two adjacent first belts left and right. The front end of the transition belt faces the first spacing, so that the rear end rotating shaft simultaneously connects the first belts and the transition belt, and the rear end of the first belt is connected to the front end of the transition belt to jointly guide the mattress. Along the corner angle between the transition belt and the lower conveying mechanism, the upward flipping of the mattress can be assisted, that is, the rolling and wrapping operation of the mattress is assisted, which is beneficial to improving the success rate of mattress rolling and wrapping.
[0011] According to some embodiments of the present invention, the rolling and wrapping mechanism further includes a second drive and a second belt. The second belt is arranged around a plurality of rollers. The second drive is used to drive the rollers to rotate. The second conveying surface is the plane of the second belt close to the upper frame. The roller close to the lower conveying mechanism is the second roller shaft.
[0012] Specifically, the second belt is arranged around a plurality of rollers. The arrangement of the second belt is beneficial to increasing the contact area between the rolling and wrapping mechanism and the mattress. The rotation of the rollers can drive the second belt to rotate. Under the rotating action of the second belt, the mattress is flipped from bottom to top. The roller close to the lower conveying mechanism is the second roller shaft, that is, the transition assembly and the rolling and wrapping mechanism share a roller, so that the rear end of the transition assembly is connected to the rolling and wrapping mechanism, and the connection between the transition belt and the second belt is more compact. When the mattress is conveyed along the rolling and wrapping mechanism to the transition assembly, along the corner angle between the transition belt and the first conveying surface, the mattress is conveyed to the rolling and wrapping mechanism. Under the action of the flipping drive, the flipping bracket can rotate forward or backward relative to the lower conveying mechanism, that is, adjust the corner angle between the flipping bracket and the lower conveying mechanism. Along the corner angle between the flipping bracket and the transition belt and the rotation of the rollers on the flipping bracket, the upward flipping of the mattress can be assisted, that is, the rolling and wrapping operation of the mattress is assisted, which is beneficial to improving the success rate of mattress rolling and wrapping.
[0013] According to some embodiments of the present invention, a plurality of second belts are provided. The plurality of second belts are arranged at intervals left and right. A second spacing is formed between two adjacent second belts left and right. The rear end of the transition belt faces the second spacing.
[0014] The rolling and wrapping mechanism further includes a plurality of second belts arranged at intervals left and right. A second spacing is formed between two adjacent second belts left and right. The rear end of the transition belt faces the second spacing, so that the roller close to the lower conveying mechanism simultaneously connects the second belt and the transition belt, and the rear end of the second belt is connected to the transition belt to jointly guide the mattress. Along the corner angle between the transition belt and the rolling and wrapping mechanism, the upward flipping of the mattress can be assisted, that is, the rolling and wrapping operation of the mattress is assisted, which is beneficial to improving the success rate of mattress rolling and wrapping.
[0015] According to some embodiments of the present invention, the transition assembly further includes a rotating sleeve, which includes an inner ring and an outer ring that are rotatably connected to each other. The inner ring is sleeved on the first roller shaft or the second roller shaft, and the outer ring is connected to the transition belt.
[0016] Considering that the rotational drive of the lower conveying mechanism and the rotational drive of the wrapping mechanism are independent of each other, in order to realize the rotation of the transition belt, the transition assembly further includes a rotating sleeve, which includes an inner ring and an outer ring arranged inside and outside. The inner ring and the outer ring are rotatably connected, the inner ring is sleeved on the first roller shaft or the second roller shaft, and the outer ring is connected to the transition belt, which is beneficial to realize the rotation of the transition belt relative to the rotating roller or the rotating shaft, so that the rotation of the transition belt is independent of the rotation of the lower conveying mechanism or the wrapping mechanism, thereby realizing the rotation of the transition belt. Moreover, the transition belt is arranged at an angle with the first conveying surface and the second conveying surface, which is beneficial to make the rotation angle of the flipping bracket relative to the lower conveying mechanism smoother, so that the transition of the mattress between the lower conveying mechanism and the wrapping mechanism is smoother, and thus the mattress can be flipped upward along the slope of the transition belt and the slope of the second conveying surface, so as to facilitate the wrapping of the mattress and improve the success rate of mattress wrapping, and is beneficial to avoid the problem of wrapping failure caused by the mattress being folded in half.
[0017] According to some embodiments of the present invention, the present invention further includes an unwinding mechanism connected to the frame. The wrapping mechanism and the frame enclose a wrapping space, and a film inlet is provided in the wrapping space. The unwinding mechanism includes a driving assembly, a film bracket, a first unwinding roller and a guiding roller. The film bracket, the first unwinding roller and the guiding roller are all rotatably connected to the frame and are parallel to each other. The film bracket is used for releasing the film. The guiding roller is arranged between the film inlet and the first unwinding roller. A conveyor belt is wound between the first unwinding roller and the guiding roller. The conveyor belt is used for conveying the released film to the film inlet. The driving assembly is used for driving the first unwinding roller or the guiding roller to rotate.
[0018] The wrapping mechanism is connected to the frame and encloses a wrapping space. The mattress is transported to the wrapping space. Under the action of the wrapping mechanism, the mattress is wrapped in the wrapping space. At the same time, the unwinding mechanism operates. Through the driving action of the driving component, the first unwinding roller or the guide roller can be rotated. A conveyor belt is arranged between the first unwinding roller and the guide roller. That is, the first unwinding roller and the guide roller are transmission-connected so that the first unwinding roller and the guide roller rotate synchronously. The film holder gradually releases the film. The guide roller is arranged between the first unwinding roller and the film inlet. The released film can abut against the conveyor belt. The use of the conveyor belt can enhance the guiding effect on the film conveyance and make the film conveyed straight to the film inlet, which is beneficial to the alignment of the film and the film inlet, and the film passes through the film inlet into the winding space, so that the film can be rolled together with the mattress in the winding space, and the mattress can be packed. The mattress rolling machine uses the guide roller and the conveyor belt arranged between the guide roller and the first unwinding roller, which is beneficial to enhance the guiding and conveying effect on the film, reduce the influence of viscosity and static electricity on the film, and ensure that the film can pass through the film inlet and enter the winding space, so as to realize the normal operation of mattress rolling and packaging.
[0019] According to some embodiments of the present invention, the present invention also includes an upper conveying mechanism, a lifting drive and a guide assembly. The lifting drive is connected to the upper frame and is transmission-connected to the upper conveying mechanism to drive the upper conveying mechanism to lift and lower. The guide assembly includes a guide column and a plurality of guide wheels. The guide column is extended up and down and is connected to the upper end of the upper conveying mechanism. The plurality of guide wheels are rotatably connected to the upper frame and are arranged around the guide column. The guide wheels are rollingly connected to the guide column.
[0020] The upper conveying mechanism is movably connected to the upper frame, and the lower conveying mechanism is connected to the lower frame. The upper frame and the lower frame are arranged opposite to each other to jointly form an input channel for the mattress. When the mattress is transported between the upper conveying mechanism and the lower conveying mechanism, the mattress is gradually transported into the rolling space under the conveying action of the upper conveying mechanism and the lower conveying mechanism to realize the rolling operation of the mattress. The lifting drive is connected to the upper frame and is transmission-connected with the upper conveying mechanism to drive the upper conveying mechanism to lift and lower, that is, the upper conveying mechanism is closer to or farther away from the lower conveying mechanism. The guide column is extended up and down and connected to the upper end of the upper conveying mechanism. The guide column rises and falls with the lifting and lowering of the upper conveying mechanism. A plurality of guide wheels are hinged to the upper frame and arranged around the guide column. In the process of lifting and lowering the upper conveying mechanism, the guide column can slide up and down relative to the plurality of guide wheels, and the guide wheel is rollingly connected to the guide column. The limiting action of the plurality of guide wheels on the guide column is conducive to guiding the lifting and lowering of the upper conveying mechanism, so that the lifting and lowering of the upper conveying mechanism remains stable, so that after the upper conveying mechanism moves downward, it can fully fit with the upper end of the mattress to maintain the conveying action on the mattress.
[0021] According to some embodiments of the present invention, two guide wheels are provided, one of which is a limiting wheel and the other is a roller, the roller is fitted with the side surface of the guide column, and the limiting wheel is embedded and connected with the side surface of the guide column.
[0022] In order to further enhance the limiting effect of the guide wheel on the guide post, two guide wheels are arranged, one is the limiting wheel and the other is the roller, and the roller is kept in contact with the side of the guide post, that is, the roller is rollingly connected to the side of the guide post, thereby realizing the limiting effect of the roller on the guide post, and the limiting wheel is embedded in the side of the guide post to enhance the limiting effect of the limiting wheel on the guide post. Through the cooperation of the limiting wheel and the guide post, it is beneficial to guide and limit the lifting and lowering of the guide post from multiple directions, thereby making the lifting and lowering of the upper conveying mechanism more stable, so that after the upper conveying mechanism moves downward, it can fully fit with the upper end of the mattress to maintain the conveying effect on the upper end of the mattress, so that the mattress can be gradually conveyed into the rolling space to realize the mattress rolling operation.
[0023] According to some embodiments of the present invention, the present invention also includes a rotating motor, a driving wheel, a driven wheel and a transmission chain. The upper frame is slidingly connected to the lower frame, the driving wheel and the driven wheel are both rotatably connected to the lower frame, the rotating motor is transmission-connected to the driving wheel, and the transmission chain is wound between the driving wheel and the driven wheel and connected to the upper frame to drive the upper frame to move closer to or away from the lower frame.
[0024] The mattress rolling machine also includes a rotating motor, a driving wheel, a driven wheel and a transmission chain. The upper frame is slidingly connected to the lower frame, the driving wheel and the driven wheel are both rotatably connected to the lower frame, the rotating motor is transmission-connected to the driving wheel, and the transmission chain is wound between the driving wheel and the driven wheel. Under the driving action of the rotating motor, the transmission chain rotates forward or reversely. The transmission chain is connected to the upper frame to drive the upper frame to slide relative to the lower frame. When the upper frame moves away from the lower frame, the rolling space between the upper frame and the lower frame is increased to adapt to the gradually increasing outer diameter of the mattress. When the mattress is rolled and packaged, the mattress can be taken out of the rolling space. Under the driving action of the rotating motor, the upper frame and the lower frame are driven to approach each other, thereby reducing the rolling space between the upper frame and the lower frame to prepare for the next mattress rolling operation.

[0055] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.
[0056] Referring to Figures 1 to 13 As shown, a mattress rolling and packaging machine according to an embodiment of the present invention includes: a frame, a lower conveying mechanism 200, an upper conveying mechanism 700, a rolling and packaging mechanism 300, and a transition component 400.
[0057] Referring to Figure 1 , Figure 2 and Figure 3 As shown, the frame includes an upper frame 110 and a lower frame 120 spaced apart vertically. The upper conveying mechanism 700 is connected to the lower end of the upper frame 110, and the lower conveying mechanism 200 is connected to the upper end of the lower frame 120, so that the upper conveying mechanism 700 and the lower conveying mechanism 200 are arranged opposite to each other. The upper conveying mechanism 700 and the lower conveying mechanism 200 together enclose a conveying channel. When the mattress is placed at the conveying channel, under the conveying action of the upper conveying mechanism 700 and the lower conveying mechanism 200, the mattress can be conveyed towards the rolling and packaging mechanism 300. The rolling and packaging mechanism 300 and the frame together enclose a rolling and packaging space, and the rolling and packaging space is communicated with the conveying channel. Under the conveying action of the upper conveying mechanism 700 and the lower conveying mechanism 200, the mattress gradually penetrates into the rolling and packaging space, and under the action of the rolling and packaging mechanism 300, the rolling and packaging operation of the mattress is realized. The lower conveying mechanism 200 has a first conveying surface.
[0058] Referring to Figure 3 and Figure 4 As shown, specifically, the rolling and packaging mechanism 300 includes a flipping drive 340, a flipping bracket 310, and a plurality of rollers 320. One end of the flipping bracket 310 is rotatably connected to the lower frame 120 and is arranged behind the lower conveying mechanism 200. The plurality of rollers 320 are arranged vertically and are all rotatably connected to the flipping bracket 310. The plurality of rollers 320 together form a second conveying surface. The flipping drive 340 can drive the flipping bracket 310 to rotate forward or backward to drive the flipping bracket 310 to approach or move away from the lower conveying mechanism 200, that is, to adjust the angular position between the flipping bracket 310 and the lower conveying mechanism 200.
[0059] Referring to Figure 4 and Figure 12 As shown, the transition component 400 includes a transition belt 430, a first roller shaft 410, and a second roller shaft 420. The first roller shaft 410 and the second roller shaft 420 both extend horizontally, and the transition belt 430 is wound between the first roller shaft 410 and the second roller shaft 420.
[0060] Referring to Figure 3 , Figure 4 and Figure 6As shown, the transition component 400 is arranged at the junction of the lower conveying mechanism 200 and the wrapping mechanism 300, and the transition belt 430 is wound between the first roller 410 and the second roller 420. The setting of the transition component 400 is conducive to making the turning angle of the flip bracket 310 relative to the lower conveying mechanism 200 smoother, so that the transition of the mattress between the lower conveying mechanism 200 and the wrapping mechanism 300 is smoother, so that the mattress can be flipped upward along the inclination of the transition belt 430 and the inclination of the flip bracket 310, so as to realize the wrapping of the mattress, improve the success rate of the mattress wrapping, and help avoid the problem of the mattress folding in half and causing the wrapping failure.
[0061] The flipping drive 340 can be a gas cylinder or an oil cylinder. The fixed end of the flipping drive 340 is connected to the lower frame 120. The movable end of the flipping drive 340 is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to the flip bracket 310. The flip bracket 310 is driven forward or reversely by the extension and contraction of the movable end relative to the fixed end to adjust the rotation angle of the flip bracket 310 relative to the lower conveying mechanism 200. When the mattress is rolled and packaged, the mattress rolling machine can drive the flip bracket 310 to flip away from the lower conveying mechanism 200 through the flipping drive 340, so that the rear end of the rolling space is opened to allow the rolled mattress to exit the rolling space.
[0062] The mattress rolling and packaging machine has a rolling and packaging state, in which the flip bracket 310 is flipped and moved closer to the first conveying surface, and the first conveying surface and the second conveying surface are arranged at an angle with the transition belt 430. That is, the height of the flip bracket 310 is higher than the height of the lower conveying mechanism 200, and the transition belt 430 is arranged between the lower conveying mechanism 200 and the rolling and packaging mechanism 300. The transition belt 430 plays a receiving and transition role, so that the mattress can be more smoothly transferred from the lower conveying mechanism 200 to the rolling and packaging mechanism 300. Under the guidance of the rolling and packaging mechanism 300, the mattress can be rolled and packaged in cooperation with the driving action of the lower conveying mechanism 200 and the upper conveying mechanism 700. The angle arrangement means that the angle between the first conveying surface or the second conveying surface and the transition belt 430 is greater than 0° and less than 180°
[0063] The corner between the wrapping mechanism 300 and the lower conveying mechanism 200 of the conventional wrapping machine is straight, and the mattress is easily folded or wrinkled when being conveyed from the lower conveying mechanism 200 to the wrapping mechanism 300, thereby causing the mattress to fail to be wrapped. The mattress wrapping machine provided by the embodiment of the present invention also includes a transition component 400, the front end of the transition component 400 is connected to the lower conveying mechanism 200, and the rear end of the transition component 400 is connected to the flip bracket 310. The wrapping state is that the first conveying surface and the second conveying surface are arranged at an angle with the transition belt 430, so as to achieve a smooth transition of the mattress from the lower conveying mechanism 200 to the flip bracket 310.
[0064] ReferenceFigure 3 As shown, it can be understood that specifically, the lower conveying mechanism 200 includes a first belt 220, a first drive, and a plurality of rotating shafts 210 arranged front and rear. The rotating shafts 210 are rotatably connected to the lower frame 120. Under the driving action of the first drive, the plurality of rotating shafts 210 rotate, and the first belt 220 is wound between the front rotating shaft 210 and the rear rotating shaft 210, that is, the lower conveying mechanism 200 is a belt conveying mechanism. The setting of the first belt 220 is beneficial to increasing the contact area between the lower conveying mechanism 200 and the mattress. The rotation of the rotating shafts 210 can drive the first belt 220 to rotate. The first conveying surface is the upper surface of the first belt 220.
[0065] When the mattress is placed on the lower conveying mechanism 200, under the conveying action of the rotating shafts 210, it is beneficial to convey the mattress from front to back. The first roller 410 is the rotating shaft 210 located at the rear end of the lower conveying mechanism 200, that is, the transition assembly 400 and the lower conveying mechanism 200 share a rotating shaft 210, so that the front end of the transition assembly 400 is connected to the lower conveying mechanism 200, and the connection between the first belt 220 and the transition belt 430 is more compact. When the mattress is conveyed along the lower conveying mechanism 200 to the transition assembly 400, following the corner angle between the transition belt 430 and the lower conveying mechanism 200, the upward flipping of the mattress can be assisted, that is, the roll-packing operation of the mattress can be assisted, which is beneficial to improving the success rate of mattress roll-packing.
[0066] Refer to Figure 6 As shown, a plurality of first belts 220 are provided, and the plurality of first belts 220 are arranged at intervals left and right. A first spacing 230 is formed between two adjacent first belts 220 left and right. The front end of the transition belt 430 faces the first spacing 230, so that the rear rotating shaft 210 simultaneously connects the first belt 220 and the transition belt 430, and the rear end of the first belt 220 is connected to the front end of the transition belt 430 to jointly guide the mattress. Following the corner angle between the transition belt 430 and the lower conveying mechanism 200, the upward flipping of the mattress can be assisted, that is, the roll-packing operation of the mattress can be assisted, which is beneficial to improving the success rate of mattress roll-packing.
[0067] Refer to Figure 1 and Figure 3 As shown, it can be understood that the roll-packing mechanism 300 further includes a second drive and a second belt 330. The second belt 330 is wound between the lower roller 320 and the upper roller 320. The setting of the second belt 330 is beneficial to increasing the contact area between the roll-packing mechanism 300 and the mattress. The rotation of the roller 320 can drive the second belt 330 to rotate. Under the rotating action of the second belt 330, the mattress is rolled up from bottom to top. The second conveying surface is the plane of the second belt 330 close to the upper frame 110.
[0068] Refer to Figure 4and Figure 12 As shown in the figure, the second roller shaft 420 is the roller 320 close to the lower conveying mechanism 200, that is, the transition assembly 400 and the wrapping and packaging mechanism 300 share a roller 320, so that the rear end of the transition assembly 400 is connected to the wrapping and packaging mechanism 300, and the connection between the second belt 330 and the transition belt 430 is more compact. When the mattress is conveyed along the wrapping and packaging mechanism 300 to the transition assembly 400, along the corner angle between the transition belt 430 and the wrapping and packaging mechanism 300, the mattress is conveyed towards the wrapping and packaging mechanism 300. Under the action of the flipping drive 340, the flipping bracket 310 can rotate forward or backward relative to the lower conveying mechanism 200, that is, adjust the corner angle between the flipping bracket 310 and the lower conveying mechanism 200. Along the corner angle of the flipping bracket 310 and the rotation of the roller 320 rotatably connected to the flipping bracket 310, the upward wrapping of the mattress can be assisted, that is, the wrapping operation of the mattress can be assisted, which is beneficial to improving the success rate of the mattress wrapping.
[0069] Refer to Figure 4 and Figure 6 As shown in the figure, a plurality of second belts 330 are provided, and the plurality of second belts 330 are arranged at intervals left and right. A second spacing 350 is formed between two adjacent second belts 330 on the left and right. The rear end of the transition belt 430 is opposite to the second spacing 350, so that the lower roller 320 simultaneously realizes the connection of the second belt 330 and the transition belt 430, and the lower end of the second belt 330 is connected to the rear end of the transition belt 430 to jointly realize the guiding of the mattress. Along the inclination angle between the transition belt 430 and the wrapping and packaging mechanism 300, the upward wrapping of the mattress can be assisted, that is, the wrapping operation of the mattress can be assisted, which is beneficial to improving the success rate of the mattress wrapping.
[0070] Refer to Figure 6 As shown in the figure, it can be understood that specifically, the transition assembly 400 is provided with two transition belts 430, and the two transition belts 430 are arranged at intervals left and right. Appropriately, the lower conveying mechanism 200 is provided with three first belts 220, and the three first belts 220 are arranged at intervals left and right. Two first spacings 230 are formed between the three first belts 220 at intervals. The front end of each transition belt 430 is arranged opposite to a first spacing 230 to avoid the problem that the arrangement of the transition belt 430 hinders the front and rear arrangement of the first belt 220. The flipping bracket 310 is provided with three second belts 330, and the three second belts 330 are arranged at intervals left and right. Two second spacings 350 are formed between the three second belts 330 at intervals. The rear end of each transition belt 430 is arranged opposite to a second spacing 350 to avoid the problem that the arrangement of the transition belt 430 hinders the up and down arrangement of the second belt 330.
[0071] The flipping mechanism is provided with two rollers 320. Both of the two rollers 320 extend left and right, and the two rollers 320 are arranged vertically, while the second belt 330 is wound between the two rollers 320.
[0072] Referring to Figure 3 、 Figure 4 and Figure 12 As shown, it can be understood that considering that the rotational drive of the lower conveying mechanism 200 and the rotational drive of the wrapping mechanism 300 are independent of each other, in order to realize the rotation of the transition belt 430, the transition assembly 400 further includes a rotating sleeve 500. The rotating sleeve 500 includes an inner ring and an outer ring arranged inside and outside. The inner ring is rotatably connected to the outer ring, the inner ring is sleeved with the first roller shaft 410 or the second roller shaft 420, and the outer ring is connected to the transition belt 430, which is beneficial to realizing the rotation of the transition belt 430 relative to the roller 320 or the rotating shaft 210.
[0073] The rotation of the transition belt 430 is relatively independent of the rotational drive of the lower conveying mechanism 200 or the wrapping mechanism 300, so as to realize the rotation of the transition belt 430. Moreover, the transition belt 430 is arranged at an angle with the lower conveying mechanism 200 and the wrapping mechanism 300, which is beneficial to making the rotation angle of the flipping bracket 310 relative to the lower conveying mechanism 200 smoother, so that the transition of the mattress between the lower conveying mechanism 200 and the wrapping mechanism 300 is smoother. The mattress can be flipped upward along the slope of the transition belt 430 and the slope of the flipping bracket 310, so as to facilitate the wrapping of the mattress and improve the success rate of mattress wrapping, and is beneficial to avoiding the problem of wrapping failure caused by the mattress being folded in half.
[0074] Specifically, rotating sleeves 500 are sleeved on both the first roller shaft 410 and the second roller shaft 420, and the rotating sleeve 500 is a bearing. The bearing is embedded and connected to the outer surface of the rotating shaft 210 or the roller 320 and is rotatably connected to the rotating shaft 210 or the roller 320 to realize the rotational movement of the transition belt 430, which is beneficial to avoiding the problem that the transition belt 430 cannot rotate due to different rotation directions or speed differences of the roller 320 or the rotating shaft 210.
[0075] Specifically, the rotating shaft 210 or the roller 320 may include multiple sub-rods. The multiple sub-rods are arranged left and right and connected. The rotating sleeve 500 is arranged at the connection of the left and right adjacent sub-rods to realize the sleeving and rotational connection of the rotating sleeve 500 with the rotating shaft 210 or the roller 320, and is beneficial to realizing the arrangement of multiple first belts 220 or second belts 330.
[0076] It should be noted that both the first drive and the second drive are rotating motors to drive the rotation of the rotating shaft 210 or the roller 320, and then drive the first belt 220 or the second belt 330 to rotate.
[0077] Referring to Figure 3 、Figure 4 and Figure 5 As shown, it can be understood that the coiling and packaging mechanism 300 further includes an upper guiding assembly and an upper turning assembly. The upper turning assembly and the upper guiding assembly are both connected to the upper frame 110. The upper conveying mechanism 700, the upper turning assembly, and the upper guiding assembly are arranged in sequence from front to back. The lower conveying mechanism 200, the flipping bracket 310, the upper guiding assembly, and the upper turning assembly jointly enclose a coiling and packaging space.
[0078] The upper conveying mechanism 700 and the lower conveying mechanism 200 can jointly enclose an input channel. The mattress is conveyed between the upper conveying mechanism 700 and the lower conveying mechanism 200. Under the conveying action of the upper conveying mechanism 700 and the lower conveying mechanism 200, the mattress passes through the input channel and enters the coiling and packaging space. The flipping bracket 310 is arranged at an angle with the lower conveying mechanism 200, and a transition assembly 400 is further provided between the flipping bracket 310 and the lower conveying mechanism 200 to gradually coil the mattress upwards. The upper turning assembly and the upper guiding assembly are arranged at an angle. The upwards flipped mattress first abuts against the upper guiding assembly. Under the guiding action of the upper guiding assembly, the end of the mattress gradually flips forwards. Under the angular guiding action of the upper turning assembly, the end of the mattress flips downwards, so that the mattress is coiled into a cylindrical shape to gradually realize the coiling and packaging operation of the mattress.
[0079] Specifically, the upper guiding assembly, the upper conveying mechanism 700, and the lower conveying mechanism 200 are all belt conveying mechanisms; the upper turning assembly includes a plurality of roller bars arranged vertically to realize the angular guiding of the mattress. Through the angular arrangement of the flipping bracket 310 and the lower conveying mechanism 200, and the angular arrangement of the upper turning assembly and the upper guiding assembly, the coiling and packaging operation of the mattress is realized.
[0080] Referring to Figure 5 、 Figure 8 and Figure 9 As shown, it can be understood that the mattress coiling and packaging machine further includes an unwinding mechanism 600. A film inlet 111 is provided between the upper guiding assembly and the upper turning assembly. Under the action of the unwinding mechanism 600, the film 690 can enter the coiling and packaging space from the film inlet 111, so that the film 690 and the mattress are coiled and packaged together. Then, through the welding and slitting of the film 690, the packaging of the mattress by the film 690 is realized.
[0081] Referring to Figure 5 、 Figure 10 and Figure 11 As shown, specifically, the unwinding mechanism 600 includes a driving assembly, a film bracket 610, a first unwinding roller 630, a second unwinding roller 620, and a guiding roller 640. Among them, the film bracket 610, the first unwinding roller 630, the second unwinding roller 620, and the guiding roller 640 are all rotatably connected to the bracket and are parallel to each other.
[0082] The film support 610 is wound with a bundle of film 690. The film support 610 can release the film 690 by rotating the film support 610. The first unwinding roller 630 and the second unwinding roller 620 are arranged side by side. The film 690 released by the film support 610 can bypass the gap between the first unwinding roller 630 and the second unwinding roller 620. The first unwinding roller 630 and the second unwinding roller 620 are both in contact with the film 690 to clamp the film 690. Compared with the first unwinding roller 630, the guide roller 640 is arranged at one end close to the film inlet 111, that is, the guide roller 640 is arranged between the first unwinding roller 630 and the film inlet 111, and a conveyor belt 650 is wound between the first unwinding roller 630 and the guide roller 640. The conveyor belt 650 is in contact with the released film 690 to convey the released film 690 to the film inlet 111.
[0083] Among them, the driving component includes a driving motor, and the output shaft of the driving motor is transmission-connected to the first unwinding roller 630 to drive the first unwinding roller 630 to rotate clockwise. Under the connection action of the conveyor belt 650, the first unwinding roller 630 and the guide roller 640 rotate synchronously. The first unwinding roller 630, the guide roller 640 and the conveyor belt 650 all rotate clockwise, and the first unwinding roller 630 and the second unwinding roller 620 are squeezed against each other to make the second unwinding roller 620 rotate counterclockwise, so that a pulling force can be applied to the film 690 clamped between the first unwinding roller 630 and the second unwinding roller 620, which is beneficial to the rotation of the film support 610, thereby increasing the length of the film 690 released by the film support 610. After the released film 690 bypasses the first unwinding roller 630 and the second unwinding roller 620, it can contact the conveyor belt 650. Under the rotation of the conveyor belt 650, the guiding and conveying effect on the film 690 can be enhanced, and the film 690 can be conveyed straight to the film inlet 111, which is conducive to the alignment of the film 690 and the film inlet 111, and the film 690 passes through the film inlet 111 into the winding space, so that the film 690 can be rolled together with the mattress in the winding space, that is, the mattress is packaged.
[0084] The wrapping machine of the related art has poor guidance and conveying performance for the film 690, and is overly dependent on the gravity of the film 690, which easily causes the film 690 to be unable to penetrate into the wrapping space to be wrapped. The mattress wrapping machine provided by the embodiment of the present invention is conducive to enhancing the guiding and conveying function of the film 690 through the guide roller 640 and the conveyor belt 650 provided between the guide roller 640 and the first unwinding roller 630, so as to realize the straight conveying of the film 690, reduce the influence of the film 690 on the viscosity and static electricity, and ensure that the film 690 can pass through the film inlet 111 and enter the wrapping space, so as to realize the normal operation of the mattress wrapping and packaging, which is conducive to improving the success rate of the mattress wrapping.
[0085] ReferenceFigure 5 , Figure 10 and Figure 11 As shown in Figure 11 , it can be understood that the unwinding device for roll packaging further includes a third unwinding roller 660. The third unwinding roller 660, the second unwinding roller 620, and the first unwinding roller 630 are arranged in sequence from top to bottom, so that the film 690 released by the film bracket 610 sequentially bypasses the third unwinding roller 660, the second unwinding roller 620, and the first unwinding roller 630, which is beneficial to increasing the contact area between the film 690 and the third unwinding roller 660, the second unwinding roller 620, or the first unwinding roller 630, and is also beneficial to keeping the film 690 flat during the conveying process. Specifically, the film bracket 610 is located behind the third unwinding roller 660. The rotation of the first unwinding roller 630 or the second unwinding roller 620 is transmitted to the film 690, thereby realizing the unwinding of the film 690. The film 690 bypassing the first unwinding roller 630 and the second unwinding roller 620 is conveyed to the film inlet 111 under the conveying action of the conveyor belt 650 to ensure that the film 690 can pass through the film inlet 111 and enter the roll packaging space, so as to realize the normal operation of mattress roll packaging and packaging.
[0086] Referring to Figure 3 , Figure 4 and Figure 5 As shown in Figure 5 , it can be understood that the unwinding device for roll packaging further includes two driven rollers 670 rotatably connected to the frame. The driven rollers 670 are all in rolling connection with the film bracket 610. The left end and the right end of the frame are both provided with chutes extending vertically. The left end of the film bracket 610 is inserted into the left chute, and the right end of the film bracket 610 is inserted into the right chute. That is, while the film bracket 610 is rotatably connected to the frame, the film bracket 610 can slide up and down relative to the frame.
[0087] The driven rollers 670 are arranged below the film bracket 610. The upper end of the driven roller 670 is in rolling connection with the lower end of the film bracket 610, and the film bracket 610 is supported between multiple driven rollers 670.
[0088] Under the action of the self-weight of the film bracket 610, the film bracket 610 is kept in contact with the driven rollers 670. As the film 690 wound on the film bracket 610 decreases, the film bracket 610 can slide downward relative to the chute, and the driven rollers 670 can always keep in contact with the film bracket 610, which is beneficial to driving the film bracket 610 to rotate synchronously to assist in realizing the release of the film 690 by the film bracket 610, is beneficial to reducing the tension applied to the film 690, thereby avoiding the problem of film 690 breakage, and is beneficial to increasing the release speed of the film 690 to meet the use requirements of mattress roll packaging.
[0089] The film support 610 is disposed between two driven rollers 670, and the upper ends of the two driven rollers 670 are in abutting and rolling connection with the lower end of the film support 610. The driving assembly further includes a transmission belt 680 which is wound between the first unwinding roller 630 and the driven roller 670 in front.
[0090] Under the connecting action of the transmission belt 680, the first unwinding roller 630 and the driven roller 670 in front rotate synchronously. When the driving motor drives the first unwinding roller 630 to rotate, the first unwinding roller 630 can drive the driven roller 670 in front to rotate through the transmission belt 680, and the rotation directions of the first rotating shaft 210 and the driven roller 670 are the same. Through the rolling connection between the driven roller 670 and the film support 610, the film support 610 is driven to rotate synchronously, and the film support 610 rotates reversely, so that the film support 610 can release the film 690 to the third unwinding roller 660, which helps to realize the release of the film 690 by the film support 610, is beneficial to reducing the tension applied to the film 690, thus avoiding the problem of film 690 breakage, and is beneficial to improving the release speed of the film 690 to meet the use requirements of mattress rolling and packaging. The rear driven roller 670 rotates as the film support 610 rotates. Through the rolling connection between the two driven rollers 670 and the film support 610, the rotation of the film support 610 is assisted to make the film 690 on the film support 610 gradually released to the third unwinding roller 660.
[0091] It can be understood that the mattress rolling and packaging machine further includes a chain drive 1000. The upper frame 110 and the lower frame 120 are slidably connected in an inclined direction. The chain drive 1000 can be used to drive the upper frame 110 to slide relative to the lower frame 120, so that the upper frame 110 moves away from the lower frame 120, thereby increasing the rolling and packaging space between the upper frame 110 and the lower frame 120 to adapt to the gradually increasing outer diameter of the rolled mattress. The lifting drive 800 is connected to the upper frame 110 and is in transmission connection with the upper conveying mechanism 700 to drive the upper conveying mechanism 700 to lift.
[0092] After the chain drive 1000 drives the upper frame 110 to move away from the lower frame 120, the lifting drive 800 can drive the upper conveying mechanism 700 to move downward, so that the upper conveying mechanism 700 approaches the lower conveying mechanism 200, thereby compensating for the upward movement stroke of the upper frame 110, so that the upper conveying mechanism 700 and the lower conveying mechanism 200 jointly realize the fitting and conveying of the mattress to ensure that the mattress is gradually conveyed into the rolling and packaging space. Under the action of the rolling and packaging mechanism 300, the complete rolling and packaging of the mattress is realized. The lower end of the lifting drive 800 can be hinged to the upper end of the upper conveying mechanism 700.
[0093] Considering that when the upper conveying mechanism 700 is lifted or lowered, it is prone to shaking or skewing, resulting in the upper conveying mechanism 700 being unable to remain in contact with the upper end of the mattress. The mattress wrapping machine further includes a guiding assembly 900. The guiding assembly 900 includes a guide post 910 and a plurality of guiding wheels. The two ends of the guide post 910 extend vertically, and the guide post 910 is connected to the upper end of the upper conveying mechanism 700. The guiding wheels are hinged to the upper frame 110 and can rotate relative to the upper frame 110. The plurality of guiding wheels are arranged around the guide post 910 and maintain a rolling connection with the guide post 910.
[0094] The lifting drive 800 is connected to the upper frame 110 and is in transmission connection with the upper conveying mechanism 700 to drive the upper conveying mechanism 700 to lift or lower, so that the upper conveying mechanism 700 approaches or moves away from the lower conveying mechanism 200. The guide post 910 rises and falls with the lifting and lowering of the upper conveying mechanism 700. The plurality of guiding wheels are hinged to the upper frame 110 and are arranged around the guide post 910. During the lifting and lowering of the upper conveying mechanism 700, the guide post 910 can slide up and down relative to the plurality of guiding wheels, and the guiding wheels are in rolling connection with the guide post 910. The limiting effect of the plurality of guiding wheels on the guide post 910 is beneficial to guiding the lifting of the upper conveying mechanism 700, so that the lifting of the upper conveying mechanism 700 remains stable. After the upper conveying mechanism 700 moves down, it can be in full contact with the upper end of the mattress to maintain the conveying effect on the mattress.
[0095] Refer to Figure 8 , Figure 9 and Figure 13 As shown in
[0096] Refer to Figure 13 As shown, specifically, the limiting wheel 920 is provided with an annular groove 921, and the side of the guide post 910 is provided with a convex strip 911 extending vertically. The convex strip 911 is embedded and connected in the annular groove 921. The limiting wheel 920 is in rolling connection with the convex strip 911. During the rotation of the limiting wheel 920, the convex strip 911 is always embedded and connected in the annular groove 921. By the abutment of the outer surface of the convex strip 911 and the inner surface of the annular groove 921, the limiting effect of the limiting wheel 920 on the guide post 910 is enhanced, so that the lifting of the upper conveying mechanism 700 is more stable. After the upper conveying mechanism 700 moves down, it can be in full contact with the upper end of the mattress to maintain the conveying effect on the upper end of the mattress, so that the mattress can be gradually conveyed into the wrapping space to realize the wrapping operation of the mattress.
[0097] Refer to Figure 8 , Figure 9 and Figure 13As shown, another guide wheel is the roller 930. The roller 930 is in contact with the side surface of the guide post 910, thereby realizing the limiting function of the roller 930 on the guide post 910. The roller 930 and the limiting wheel 920 are arranged on two adjacent side surfaces of the guide post 910. Cooperating with the limiting function and guiding function of the limiting wheel 920 on the guide post 910 is beneficial to guiding and limiting the lifting of the guide post 910 from multiple directions, thereby making the lifting of the upper conveying mechanism 700 more stable. After the upper conveying mechanism 700 moves downward, it can be fully attached to the upper end of the mattress to maintain the conveying function of the upper end of the mattress, enabling the mattress to be gradually conveyed into the wrapping space and realizing the wrapping operation of the mattress.
[0098] Referring to Figure 8 and Figure 9 As shown, it can be understood that two sets of guiding components 900 are provided, and the two sets of guiding components 900 are arranged at intervals front and back. This is beneficial to making the front end and the rear end of the upper conveying mechanism 700 more balanced during lifting, beneficial to avoiding the problem that the upper conveying mechanism 700 tilts forward or backward, resulting in the inability to keep in contact with the mattress after the upper conveying mechanism 700 moves downward, beneficial to improving the stability of the lifting of the upper conveying mechanism 700, and beneficial to enhancing the guiding effect on the lifting of the upper conveying mechanism 700.
[0099] The mattress wrapping machine further includes a connecting rod 940. The two ends of the connecting rod 940 extend front and back. The front end of the connecting rod 940 is connected to the front guide post 910, and the rear end of the connecting rod 940 is connected to the rear guide post 910, that is, the front and rear guide posts 910 are connected as a whole, which is beneficial to maintaining the synchronization of the front and rear guide posts 910, beneficial to making the front end and the rear end of the upper conveying mechanism 700 more balanced during lifting, beneficial to avoiding the problem that the upper conveying mechanism 700 tilts forward or backward, resulting in the inability to keep in contact with the mattress after the upper conveying mechanism 700 moves downward, beneficial to improving the stability of the lifting of the upper conveying mechanism 700, and beneficial to enhancing the guiding effect on the lifting of the upper conveying mechanism 700.
[0100] Referring to Figure 8 and Figure 9As shown, it can be understood that specifically, in order to achieve the synchronous operation of the left and right lifting drives 800, two lifting drives 800 are provided, and the two lifting drives 800 are arranged at intervals left and right. The mattress wrapping machine further includes a coupling shaft 1130 and two groups of synchronous components 1100 arranged at intervals left and right. Each group of synchronous components 1100 is correspondingly arranged for one lifting drive 800. The synchronous component 1100 includes a rack 1110 and a gear 1120. The gear 1120 is hinged to the upper frame 110. The rack 1110 extends vertically and is connected to the upper end of the upper conveying mechanism 700. When the upper conveying mechanism 700 lifts and lowers, the rack 1110 can slide relative to the gear 1120 and be meshed and connected. One end of the coupling shaft 1130 is connected to the left gear 1120, and the other end of the coupling shaft 1130 is connected to the right gear 1120. Under the connection action of the coupling shaft 1130, the synchronous operation of the left and right synchronous components 1100 can be realized, which is beneficial to the synchronous operation of the left and right lifting drives 800, so that the left end and the right end of the upper conveying mechanism 700 remain balanced when lifting and lowering, which is beneficial to avoiding the problem that the upper conveying mechanism 700 cannot be attached to the mattress after tilting to the left or right when moving downward, which is beneficial to improving the smoothness of the lifting of the upper conveying mechanism 700 and is beneficial to enhancing the guiding effect on the lifting of the upper conveying mechanism 700.
[0101] It should be noted that the lifting drive 800 can be a linear drive mechanism such as a cylinder, an oil cylinder, a screw slider mechanism, etc.
[0102] Refer to Figure 6 and Figure 7 As shown, it can be understood that inclined slide rails 121 are provided at both the left end and the right end of the lower frame 120, and the left end and the right end of the upper frame 110 are respectively slidably connected to the two slide rails 121. Two chains 1010 are arranged in a transmission manner, and the chain 1010 transmissions are arranged in one-to-one correspondence with the slide rails 121.
[0103] The chain drive 1000 includes a sprocket 1020, a chain 1010 and a counterweight 1030. Two sprockets 1020 are provided, and the two sprockets 1020 extend vertically and are both rotatably connected to the lower frame 120. The chain 1010 is wound between the two sprockets 1020 and is meshed and connected with the sprockets 1020. The counterweight 1030 is connected to one side of the chain 1010 so that the sprocket 1020 has a tendency to rotate forward.
[0104] The sprocket 1020 is rotatably connected to the lower frame 120, and the upper sprocket 1020 is coaxially connected with a driving wheel. The driving wheel is arranged at one end of the slide rail 121, and the other end of the slide rail 121 is rotatably connected with a driven wheel. A transmission chain is wound between the driving wheel and the driven wheel, and the transmission chain is connected to the upper frame 110.
[0105] Refer to Figure 6 andFigure 7 As shown, the mattress wrapping machine further includes a rotating motor and a transmission shaft. The left end of the transmission shaft is connected to the sprocket 1020 of the left chain drive 1000, and the right end of the transmission shaft is connected to the sprocket 1020 of the right chain drive 1000. The rotating motor is in transmission connection with the transmission shaft to drive the transmission shaft to rotate forward or backward. When the rotating motor drives the transmission shaft to rotate forward, the sprocket 1020 is driven to rotate forward. Under the connection of the chain 1010, the two sprockets 1020 are driven to rotate synchronously. The driving wheel is coaxially arranged with one of the sprockets 1020, so that the driving wheel rotates forward, and then the transmission chain rotates forward. The upper frame 110 slides upward along the slide rail 121, and the upper frame 110 and the lower frame 120 move away from each other, so that the wrapping space gradually increases. The setting of the counterweight 1030 is beneficial to balancing the weight of the upper frame 110 and reducing the load of the rotating motor, which is beneficial to cost saving.
[0106] The rotating motor can drive the transmission shaft to rotate reversely. Under the transmission of the chain drive 1000, the upper frame 110 slides downward relative to the lower frame 120, so that the upper frame 110 and the lower frame 120 approach each other, and the wrapping space gradually decreases, preparing for the wrapping operation of the next mattress.
