[0043] It can be understood that the roll-feeding device includes a feed roller group and a slitting end, and the feed roller group includes at least two roller strips extending left and right, and the two roller strips are arranged front to back, and an upward feed port is formed between the two roller strips, so that the lower packaging film is unrolled to the feed port, and in conjunction with the conveying action of the conveying device 100, the lower packaging film can be unrolled onto the conveying surface of the conveying device 100.

[0044] When the length of the lower packaging film unwound onto the conveying surface of the conveying device 100 reaches a set threshold, the worker can load the sofa onto the conveying device 100, and the sofa is pressed on top of the lower packaging film. As the conveying device 100 conveys, the lower packaging film and the sofa are conveyed forward together, and the lower packaging film is wrapped under the entire sofa.

[0045] The slitting end can be a cutter, and the roll feeding device can drive the cutter to slide left and right through a linear drive device, and the cutter abuts against the lower packaging film to achieve the slitting of the lower packaging film. After the slitting is completed, the lower packaging film and the sofa are transported forward together. The linear drive device can be an oil cylinder, an air cylinder, a belt conveyor mechanism, etc.

[0046] Understandably, see Figure 1 and Figure 2 The left moving assembly is located on the left side of the conveying device 100, and the right moving assembly is located on the right side of the conveying device 100. The left moving assembly and the right moving assembly are arranged opposite to each other on the left and right sides.

[0047] The left moving assembly includes a first sewing end 210 movable in the front-to-back direction, a first pressing end 220 capable of approaching or moving away from the conveying device 100, and a horizontal pushing component 230.

The front end and rear end of the first transmission rod 421 are both connected to the first transmission wheel, and the first transmission wheel is rotatably connected to the crossbeam frame 410. The right ends of the first crossbeam and the second crossbeam are both rotatably connected to the second transmission wheel. A first transmission belt 422 is arranged around the first transmission wheel and the second transmission wheel. The front end of the first sliding block 423 is connected to the first transmission belt 422 in the front, and the rear end of the first sliding block 423 is connected to the first transmission belt 422 in the rear. The first motor drives the first transmission rod 421 to rotate, thereby driving the front and rear first transmission belts 422 to rotate synchronously, thereby causing the first sliding block 423 to slide left and right to realize left and right driving of the clamp 430.

[0058] The movable mechanism also includes a second motor, a second transmission rod 426, a transmission gear 424, a rack 425 and a connecting rod 427. The two ends of the second transmission rod 426 are extended forward and backward. The second motor and the second transmission rod 426 are both connected to the first sliding block 423. The second motor is used to drive the second transmission rod 426 to rotate forward or flip. The front end and the rear end of the second transmission rod 426 are both connected to the transmission gear 424, and the front end and the rear end of the connecting rod 427 are both connected to the rack 425 extending upward. The rack 425 corresponds to the transmission gear 424 one by one and is meshed for transmission. A plurality of clamps 430 are provided, and the plurality of clamps 430 are all connected to the connecting rod 427 and are arranged at intervals along the connecting rod 427.

[0059] When it is necessary to clamp and stretch the unrolled packaging film, the first motor operates to drive the first transmission rod 421 to rotate. The first transmission rod 421 rotates through the first transmission wheels at the left and right ends, thereby driving the first transmission belt 422 wound between the first transmission wheel and the second transmission wheel to rotate forward or reverse. Since the front end of the first sliding block 423 is connected to the first transmission belt 422, and the rear end of the first sliding block 423 is connected to the second transmission belt, the first sliding block 423 can be driven to move to the right. When the first sliding block 423 approaches the right motion component. The second motor operates and drives the second transmission rod 426 to rotate. The second transmission rod 426 is driven by the meshing transmission of the transmission gear 424 and the rack 425 at the left and right ends, thereby driving the connecting rod 427 to descend to the side close to the unwinding component 330. The clamping claw 430 can clamp the upper packaging film unwound at the unwinding component 330, and then the connecting rod 427 moves upward and resets to the left, so that the upper packaging film and the lower packaging film together form a cavity for the sofa to penetrate, and cooperate with the left motion component and the right motion component to realize the packaging of the sofa by the upper packaging film and the lower packaging film.

[0060] Understandably, see Figure 1 and Figure 2 In order to improve the packaging efficiency of the sofa, the sofa packaging device also includes a limit assembly 600, and the limit assembly 600 is arranged on the left side of the unwinding component 330. The limit assembly 600 includes a front column, a rear column, a baffle and a second lifting drive. The front column and the rear column are respectively located in front of and behind the unwinding component 330. The front end and the rear end of the baffle are respectively movably connected to the front column and the rear column. The front end and the rear end of the baffle slide along the up and down directions with the front column and the rear column respectively. The second lifting drive is transmission-connected to the baffle to drive the baffle to move up and down.

[0061] When in use, after the clamping claw 430 of the covering component 400 clamps the unrolled upper packaging film, the upper packaging film can be moved upward so that the upper packaging film passes through between the baffle and the unwinding component 330. The second lifting drive can drive the baffle to move upward synchronously with the upper packaging film. Then the covering component 400 can drive the upper packaging film to move right. Under the limiting action of the baffle, the upper packaging film is set in an L shape, so that the upper packaging film and the lower packaging film together form a rectangular cavity. With the operation of the conveying device 100, the sofa is inserted into the rectangular cavity, and the upper packaging film and the lower packaging film can wrap the sofa.

[0062] If the covering component 400 is moved before the sofa is in place, the upper packaging film will sag due to its own gravity, and the drooping packaging film will be located on the conveying track of the sofa, thereby affecting the conveying of the sofa. The sofa packaging device, through the setting of the limiting component 600, limits the upper packaging film through the baffle, thereby increasing the cavity surrounded by the upper packaging film and the lower packaging film. In conjunction with the conveying function of the conveying device 100, the sofa can be inserted between the upper packaging film and the lower packaging film, thereby saving waiting time and improving the packaging efficiency of the sofa.

[0063] If the covering assembly 400 is activated after the sofa is in place, the upper packaging film can cover the upper part of the sofa, but it will inevitably prolong the packaging time of the entire sofa, which is not conducive to improving the efficiency of sofa packaging.

[0064] It can be understood that the second lifting drive may include a driving motor, a belt and a transmission wheel, at least two transmission wheels are rotatably connected to the upper and lower ends of the front column, the belt is wound between the upper and lower transmission wheels, the driving motor can drive the belt to rotate forward or reverse, and the front end of the baffle is connected to the belt, so that the baffle can be driven to rise and fall, providing a support point for the upper packaging film close to the right moving component, so that the upper packaging film and the lower packaging film together form a cavity for the sofa to penetrate.

[0065] Understandably, see Figure 3 and Figure 4 , considering that some sofas have corners, when the packaging film is closely attached to the contour of the sofa, the edges of the cut upper packaging film are not flush, which is not conducive to the clamping and packaging of the upper packaging film next time. For example, some sofas are L-shaped, and when the sofa is placed on the conveying device 100, the length direction of the sofa is generally consistent with the conveying direction of the conveying device 100. If the upper packaging film and the lower packaging film are tightened along the contour of the sofa, the sofa can be tightly packaged, but the edges of the upper packaging film after cutting are not flush, and it is difficult for the covering component 400 to clamp the upper packaging film. Therefore, the sofa packaging device also includes a suspension component 500. The suspension component 500 includes a suspension rod 530 that can be telescopically extended forward. The suspension rod 530 abuts against the upper packaging film to compensate for the gap of the sofa, so that the edges of the upper packaging film after cutting are more flush.

[0066] Specifically, the suspension assembly 500 includes a frame, a first telescopic drive 510, a first lifting drive 520 and a suspension rod 530. The suspension rod 530 is extended forward and backward. The first telescopic drive 510 and the first lifting drive 520 are both connected to the frame. The frame includes a first column and a second column extending up and down. The first column and the second column are arranged with a front-to-back interval.

[0067] The first lifting drive 520 includes a third motor, a third transmission rod 522, a second transmission chain 521, a first sprocket and a connecting plate 523. The front end and rear end of the third transmission rod 522 are rotatably connected to the first column and the second column respectively, the front end and rear end of the third transmission rod 522 are both connected to the first sprocket, the lower ends of the first column and the second column are both rotatably connected to the first sprocket, the second transmission chain 521 is wound between the upper and lower first sprockets, and the front end and rear end of the connecting plate 523 are respectively connected to the front and rear second transmission chains 521. Under the driving action of the third motor, the front and rear second transmission chains 521 can be made to rotate synchronously, thereby driving the connecting plate 523 to move up and down, and the suspension rod 530 is connected to the connecting plate 523 to realize the lifting and lowering drive of the suspension rod 530.

[0068] The first telescopic drive 510 includes a fourth motor, a first transmission chain 511, a second sprocket and a second sliding block 512. The left surface of the connecting plate 523 is rotatably connected to two second sprockets, the two second sprockets are arranged in a front-to-back interval, and the first transmission chain 511 is wound between the two second sprockets. The fourth motor is connected to one of the second sprockets to drive the first transmission chain 511 to rotate forward or reverse. The second sliding block 512 is connected to the first transmission chain 511 to drive the second sliding block 512 to move forward and backward. The rear end of the suspension rod 530 is connected to the second sliding block 512, thereby driving the suspension rod 530 to telescope forward and backward.

[0069] The first lifting drive 520 can be used to drive the suspension rod 530 to move up and down to adjust the height position of the suspension rod 530, and the first telescopic drive 510 can be used to drive the suspension rod 530 to move forward and backward, so that the suspension rod 530 can be placed between the left moving component and the right moving component. When the covering component 400 stretches the unrolled upper packaging film, the suspension rod 530 can compensate for the cavity existing at the corner of the sofa, which is beneficial for the upper packaging film and the lower packaging film to form a wrapping cavity with consistent front and back volumes, thereby making the edges of the upper packaging film after cutting more flush, so that the covering component 400 can continuously clamp and stretch the upper packaging film for multiple times, which is beneficial for improving the efficiency of sofa packaging.

[0070] Understandably, see Figure 1 and Figure 2 In order to further improve the stability and flatness of the sealing part of the packaging bag, the first sewing end 210 and the second sewing end 310 both include a front-to-back translation drive, a loading platform, a hemming cylinder and a sewing machine. The hemming cylinder and the sewing machine are both connected to the loading platform, the hemming cylinder is located behind the sewing machine, and the front-to-back translation drive is used to drive the loading platform to slide forward and backward.

[0071] The folding cylinder and the sewing machine are both connected to the loading platform. The folding cylinder is located at the rear of the sewing machine. The front and rear translation drive can drive the loading platform to move backward, so that the upper packaging film and the lower packaging film are inserted into the folding cylinder together. Under the guidance of the folding cylinder, the upper packaging film and the lower packaging film are folded in half together. Under the sewing action of the sewing machine, the folded upper packaging film and the lower packaging film are sewn together as one, which is beneficial to enhance the stability of the packaging bag at the sealing part. Moreover, by folding the upper packaging film and the lower packaging film in the folding cylinder, the left edge and the rear edge of the packaging bag are kept flat, so as to facilitate the later transportation.

[0072] The folding cylinder comprises a cylinder body and a first guide member, wherein a first cavity and a second cavity are arranged in an up-and-down manner in the cylinder body, wherein the first cavity is arranged to penetrate from front to back, and the first cavity is opened to the left, and the edges of the upper packaging film and the lower packaging film can penetrate into the first cavity from the rear end and the left end of the cylinder body, and the right end of the first cavity is connected with the right end of the second cavity, and the first guide member extends from back to front and from top to bottom, and under the guiding action of the first guide member, the upper packaging film and the lower packaging film can be folded from the first cavity to the second cavity, and the first cavity extends from back to front and from right to left, and the upper packaging film and After the lower packaging film passes through the second cavity, under the guiding action of the first guide member, the edges of the upper packaging film and the lower packaging film can be gradually folded in half, so as to achieve the sealing of the packaging bag under the binding of the sewing machine. Compared with the simple superposition of two layers of packaging film, the folding tube can be used to fold the upper packaging film and the lower packaging film, which is beneficial to enhance the connection stability of the packaging bag at the sealing point by cooperating with the sealing of the sewing machine. Moreover, through the width limitation of the first cavity, the edge of the folded packaging film can be made smoother, so as to enhance the packaging effect of furniture such as sofas.

[0073] The front and rear translation drive includes a guide rail, a drive motor, a belt and a roller. The belt is wound around the front and rear rollers, and the drive motor is used to drive the rollers to rotate, thereby driving the belt to rotate forward or reverse. The two ends of the guide rail are extended forward and backward, the rollers are rotatably connected to the guide rails, the stage is slidably connected to the guide rails, and the lower end of the stage is connected to the belt. With the forward or reverse rotation of the belt, the stage can realize reciprocating motion in the front and rear directions.

[0074] The second sewing end 310 of the right moving assembly also includes a cutter, which is connected to the stage and located behind the folding tube, that is, when the stage moves backward, the cutter first abuts against the upper packaging film to achieve slitting of the upper packaging film.

[0075] Understandably, see Figure 2Considering the difference in width of different sofas, the conveying device 100 includes a first conveying end 110 and a second conveying end 120 extending forward and backward, and the first conveying end 110 and the second conveying end 120 are arranged at a left-right interval. The left motion component includes a first fixed frame 240, a first sliding frame 250 and a left-right sliding drive, and the left-right sliding drive is used to drive the first sliding frame 250 to slide left and right relative to the first fixed frame 240. The first conveying end 110, the first sewing end 210, the first clamping end 220 and the horizontal pushing component 230 are all connected to the first sliding frame 250.

[0076] The first conveying end 110 and the second conveying end 120 are both belt conveying mechanisms, and the first conveying end 110 and the second conveying end 120 are both extended forward and backward. Under the synchronous conveying action of the first conveying end 110 and the second conveying end 120, the sofa can be conveyed from back to front. The first conveying end 110 and the second conveying end 120 are arranged at intervals from left to right, and the first conveying end 110 is connected to the first sliding frame 250. The left and right sliding drive can drive the first sliding frame 250 to slide left and right relative to the first fixed frame 240, thereby adjusting the distance between the first conveying end 110 and the second conveying end 120, so that the sofa packaging device can be suitable for the packaging of various sofas.

[0077] The first sewing end 210, the first pressing end 220 and the horizontal pushing component 230 are all connected to the first sliding frame 250 to ensure that the first sewing end 210 can achieve the sealing of the upper packaging film and the lower packaging film, the first pressing end 220 can achieve the fitting of the upper packaging film and the lower packaging film, and the horizontal pushing component 230 can push the sofa to the right to tighten the gap between the packaging bag and the sofa, so that the packaging bag is more closely attached to the surface of the sofa.

[0078] Specifically, the left and right sliding drive can be a linear drive mechanism such as an oil cylinder, an air cylinder, or a linear motor.

[0079] It can be understood that, similarly, the right motion assembly includes a second fixed frame, a second sliding frame and a left-right sliding drive, the left-right sliding drive is used to drive the second sliding frame to slide left-right relative to the second fixed frame, and the second conveying end 120, the second sewing end 310, the second pressing end 320 and the unwinding component 330 are all connected to the second sliding frame. The left-right sliding drive can drive the second sliding frame to slide left-right relative to the second fixed frame, thereby adjusting the distance between the first conveying end 110 and the second conveying end 120, so that the sofa packaging device can be applied to the packaging of various sofas.

[0080] Understandably, see Figure 2In order to achieve the clamping and stretching of the upper packaging film by the covering component 400, the unwinding component 330 also includes a fixed plate, a clamping plate and a clamping drive. The clamping drive is connected to the clamping plate transmission. The winding roller can unwind the upper packaging film between the fixed plate and the clamping plate. The clamping drive is used to drive the clamping plate and the fixed plate to move closer or farther away.

[0081] The winding roller can unwind the upper packaging film between the fixed plate and the clamping plate, and the clamping drive can drive the clamping plate and the fixed plate to approach each other to clamp the upper packaging film between the fixed plate and the clamping plate to fix the position of the upper packaging film, so that the clamping claw 430 can clamp the upper packaging film after moving into position at a fixed point to ensure that the upper packaging film can cover the top of the sofa, and the upper packaging film and the lower packaging film can wrap the sofa together.

[0082] It is understandable that in order to facilitate the clamping jaws 430 to clamp the upper packaging film, notches are opened on the front sides of the fixed plate and the clamping plate, and multiple notches are arranged at intervals along the front and rear directions on the fixed plate and the clamping plate. The clamping jaws 430 face the fixed plate and are connected to the movable mechanism.

[0083] The unwinding component 330 can unwind the upper packaging film between the fixed plate and the clamping plate, and the clamping drive drives the clamping plate to be pressed down onto the fixed plate to clamp the upper packaging film in place, and the movable mechanism drives the clamping jaws 430 to approach the upper packaging film clamped between the fixed plate and the clamping plate, and the clamping jaws 430 grab the upper packaging film, and then the clamping drive drives the clamping plate to move up and away from the fixed plate. At this time, the movable mechanism can drive the clamping jaws 430 to bypass the baffle and reach the top of the conveying device 100, and lay the upper packaging film on the top side of the sofa for wrapping protection. When the first pressing end 220 presses the upper packaging film, the clamping jaws 430 return to reset.

[0084] It can be understood that there are multiple unwinding parts 330, and the multiple unwinding parts 330 are arranged at intervals in the vertical direction. Different unwinding parts 330 can be equipped with packaging bags of different widths. In actual applications, the fixed plate, the clamping plate and the clamping drive are a group, and multiple groups are arranged in the vertical direction on the second fixed frame where the right motion component is located. Multiple winding rollers are respectively unwound between multiple groups of fixed plates and clamping plates. When the upper packaging film is selected to package the sofa, the clamping claw 430 can be moved to different unwinding parts 330 for clamping as needed, thereby improving the flexibility of use.

[0085] Understandably, see Figure 2 The first clamping end 220 and the second clamping end 320 both include a pressing plate 321, a connecting rod mechanism 322 and a linear drive 323. The pressing plate 321 is rotatably connected to the connecting rod mechanism 322. The linear drive 323 is used to drive the connecting rod mechanism 322 to unfold or fold so that the pressing plate 321 moves closer to or away from the conveying surface of the conveying device 100.

[0086] When the linear drive 323 can drive the connecting rod mechanism 322 to unfold, the pressure plate 321 can be moved closer to the conveying surface of the conveying device 100, so that the pressure plate 321 can press down the upper packaging film and the lower packaging film, and the pressure plate 321 can limit the position of the sofa, so that the upper packaging film and the lower packaging film are in close contact with the sofa. The linear drive 323 can drive the connecting rod mechanism 322 to fold, so that the baffle is away from the conveying device 100, thereby avoiding the problem that the baffle hinders the conveying of the sofa.

[0087] Taking the left motion assembly as an example, the linear drive 323 and the connecting rod mechanism 322 are both connected to the first sliding frame 250, and the pressure plate 321 and the linear drive 323 are both connected to the connecting rod mechanism 322. The connecting rod mechanism 322 includes at least three connecting rods, two of which are parallel to each other, and one end of each connecting rod is rotatably connected to the first fixed frame 240, and the other end of each connecting rod is rotatably connected to the third connecting rod, and the pressure plate 321 is connected to the bottom end of the third connecting rod. The linear drive 323 transmits power to any connecting rod. The connecting rod mechanism 322 can be unfolded and folded for storage. The linear drive 323 drives the connecting rod mechanism 322 to unfold, and at this time, it can drive the pressure plate 321 to move to the first conveying end 110, and press the upper packaging film located on the upper side of the sofa down on the lower packaging film located on the bottom side of the sofa. When the first sewing end 210 sews the upper packaging film and the lower packaging film together, the linear drive 323 drives the connecting rod mechanism 322 to fold, and at this time, it can drive the pressure plate 321 to move and retract to the first sliding frame 250.

[0088] The structure of the second clamping end 320 of the right moving assembly is the same as that of the first clamping end 220, and will not be described in detail here.

[0089] It can be understood that in order to make the lower packaging film close to the conveying surface of the conveying device 100 and convey it forward, the roll feeding device also includes a pressure roller group and a blowing end, the feeding roller group has an upward discharge port, the pressure roller group and the blowing end are both located above the feeding roller group, and the pressure roller group and the blowing end can move up and down.

[0090] When the pressure roller group and the blowing end move down to the end close to the discharge port, the pressure roller group and the blowing end are respectively located in front of and behind the discharge port, and the blowing port of the blowing end is arranged toward the pressure roller group. Under the action of the blowing end, the lower packaging film sent out from the discharge port is made to approach the pressure roller group, and the lower packaging film is made to be tightly attached to the pressure roller group. Under the rotation of the pressure roller group, the lower packaging film can be unwound onto the conveying surface of the conveying device 100, thereby avoiding the problem of wrinkles and accumulation of the lower packaging film on the conveying surface of the conveying device 100, which is conducive to keeping the lower packaging film flat and conveying it forward.

[0091] The pressure roller group includes a gantry, a roll feeding lifting drive, a roll feeding lifting frame and a lower pressure roller. The gantry is connected to the top side of the roll feeding roller group, the roll feeding lifting drive is connected to the gantry, the roll feeding lifting frame is connected to the roll feeding lifting drive, the roll feeding lifting drive can drive the roll feeding lifting frame to move up and down, and the lower pressure roller is connected to the roll feeding lifting frame with a rotation axis rotating in the left and right directions.

[0092] The outer periphery of the lower pressure roller is provided with an annular groove, and a plurality of annular grooves are arranged in the left-right direction. The blowing end includes an air blowing pipe connected to the roll feeding lifting frame, and a plurality of air blowing pipes are arranged at intervals in the left-right direction.

[0093] In practical applications, multiple blowing pipes can be connected to different air supply sources or the same air supply source through pipelines. The air supply source can be an air pump, a blowing valve, etc. The multiple blowing pipes are respectively opposite to the multiple annular grooves, and one end of the blowing pipe opposite to the annular groove is the blowing end. The lower packaging film is continuously fed out at the discharge port. When the roll-feeding lifting drive drives the roll-feeding lifting frame to move downward, the lower packaging film is further flattened and conveyed by the lower pressure roller. During the conveying process, the airflow blown out from the blowing end can also pass through the annular groove to blow the lower packaging film at the discharge port to the side away from the conveying device 100, so that the lower packaging film can be smoothly conveyed to the left transfer end and the right transfer end, which is helpful to prevent the lower packaging film from folding when moving to the first conveying end 110 and the second conveying end 120.

[0094] It can be understood that, considering the problem of inaccurate alignment of the sofa being fed, the sofa packaging device also includes a feeding device, and the roll feeding device is located between the feeding device and the conveying device 100. The feeding device includes a roller drive, a left limit plate, a right limit plate and an adjustable translation drive. The roller drive is located below the left limit plate and the right limit plate. The conveying direction of the roller drive is from back to front, and the adjustable translation drive is used to drive the left limit plate and the right limit plate to move closer or farther away.

[0095] When the sofa is loaded to the roller drive, the sofa can be transported between the left limit plate and the right limit plate. The adjustment of the translation drive can drive the left limit plate and the right limit plate to approach each other, so that the sofa is clamped between the left limit plate and the right limit plate. Under the abutment of the left limit plate and the right limit plate, the placement of the sofa can be corrected so that the sofa can cooperate with the subsequent left motion assembly and the right motion assembly to realize automatic packaging of the sofa. The adjustment of the translation drive can be a linear drive mechanism such as an oil cylinder or a pneumatic cylinder.

[0096] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.

[0097] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
