Description

Technical Field

[0001] This application belongs to the field of cartoning machines, and in particular relates to a paper box liner taking, forming and boxing device. Background Technology

[0002] In the packaging industry, paper feeding and box placement for cardboard box liners are crucial production steps. Traditional manual operations are inefficient and lack precision, making them unsuitable for large-scale production. While existing cartoning machines can mechanically handle the feeding and placement of flat liners (i.e., flat paper or cardboard), folding the paper into a pre-defined three-dimensional shape and then boxing it still presents challenges due to the large number of interconnected components and low success rate and efficiency. Therefore, it is necessary to address these technical issues. Utility Model Content

[0003] The purpose of this application is to provide a paper box liner taking, forming and boxing device to solve the technical problem of low efficiency in the packaging of paper box liners in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a paper box liner taking, forming, and boxing device, comprising:

[0005] frame;

[0006] A hopper, connected to the frame and used to hold an inner liner die-cut sample, the inner liner die-cut sample comprising a body and a plurality of supporting edges connected to the edge of the body;

[0007] The transfer assembly includes a rotating shaft rotatably mounted on the frame and a connecting seat connected to the rotating shaft, as well as a suction cup and a cylinder and a plate frame respectively connected to the connecting seat. The suction cup is connected to the power end of the cylinder and can be driven by the cylinder. The plate frame is formed to fit the annular sidewall of the body. The axial direction of the annular sidewall is parallel to the moving direction of the suction cup and allows the suction cup to pass through.

[0008] A drive mechanism is connected to the rotating shaft and is used to drive the connecting seat to rotate so that the suction cup alternately faces the discharge port of the hopper and the loading opening of the target carton.

[0009] Optionally, the transfer assembly further includes a plurality of shaped guide plates arranged around the side of the plate frame opposite to the cylinder;

[0010] The forming guide plate is parallel to the moving direction of the suction cup, and all the forming guide plates cooperate to form a forming channel that is coaxial with the annular sidewall and whose shape is adapted to the body.

[0011] Optionally, the side of the forming guide plate away from the frame is formed with an arcuate portion for abutting against the support edge and facilitating the entry of the support edge into the forming channel.

[0012] Optionally, the forming guide plate has a set height in the axial direction of the forming channel so that the forming guide plate can form a gap with the filling opening of the target carton that is smaller than the width of the support edge.

[0013] Optionally, the transfer assembly further includes a movable plate whose shape is adapted to the forming channel and which is capable of passing through the forming channel;

[0014] Multiple suction cups are evenly arranged on the movable plate and connected to the cylinder through the movable plate.

[0015] Optionally, the transfer assembly further includes a gate-shaped support;

[0016] The bracket is connected to the cylinder, and the plate frame is connected to the bracket and connected to the connecting seat through the bracket and the cylinder.

[0017] Optionally, the transfer assembly further includes an ear plate;

[0018] The flap plate is connected to the opposite sides of the plate frame along the axis of rotation. The front end of the flap plate in the direction of rotation of the plate frame toward the target carton extends toward the center of the plate frame so that the flap plate can unfold the flaps on the target carton during rotation.

[0019] Optionally, a stop bar is provided at the discharge port of the hopper for abutting against the support edge, and the cross-sectional shape of the stop bar is set to be circular to facilitate the disengagement of the support edge from the hopper.

[0020] Optionally, the drive mechanism includes a servo motor and a sensor respectively connected to the frame;

[0021] The servo motor is driven and connected to the rotating shaft, and the sensor is communicatively connected to the servo motor and used to detect the rotation angle of the rotating shaft.

[0022] The beneficial effects of the paper box liner taking paper forming and boxing device provided in this application are as follows: Compared with the prior art, in the paper box liner taking paper forming and boxing device provided in this application, since the rotating shaft can drive the connecting seat to rotate when it rotates, the suction cup connected to the connecting seat can alternately face the discharge port of the hopper and the filling opening of the target paper box during the rotation of the rotating shaft. In this way, when the cylinder drives the suction cup to move, the suction cup can pick up the target paper box liner from the hopper and transfer it to the target paper box. Because the plate frame forms an annular sidewall for the suction cup to pass through, and because the shape of the annular sidewall is adapted to the body shape of the inner lining die-cut sample, when the suction cup drives the inner lining die-cut sample through the annular sidewall, the supporting edge on the inner lining die-cut sample will form a perpendicular posture to the body under the restriction of the annular sidewall, and the paper box die-cut sample will be formed into the target paper box lining. Thus, the paper box lining paper taking, forming and boxing device provided in this application can complete the steps of taking paper, forming and boxing the target die-cut sample in one go through the cooperation of the rotating shaft, cylinder and plate frame, which is far superior to the prior art.

[0035] Please refer to the following: Figures 1 to 6 This application provides a paper box liner feeding, forming, and loading device. The device includes a frame 101, a hopper 102, a transfer assembly, and a drive mechanism.

[0036] The hopper 102 is connected to the frame 101 and is used to accommodate the inner liner die-cut sample 200. The inner liner die-cut sample 200 includes a body 201 and a plurality of support edges 202 connected to the edge of the body 201. The transfer assembly includes a rotating shaft 103 rotatably mounted on the frame 101 and a connecting seat 104 connected to the rotating shaft 103. It also includes a suction cup 105 and a cylinder 106 and a plate frame 107 respectively connected to the connecting seat 104. The suction cup 105 is connected to the power end of the cylinder 106 and can be driven by the cylinder 106. The plate frame 107 forms an annular sidewall 108 whose shape is adapted to the body 201. The axial direction of the annular sidewall 108 is parallel to the moving direction of the suction cup 105 and allows the suction cup 105 to pass through. The drive mechanism is connected to the rotating shaft 103 and is used to drive the connecting seat 104 to rotate through the rotating shaft 103 so that the suction cup 105 alternately faces the discharge port of the hopper 102 and the loading opening of the target cardboard box 300.

[0037] According to the structure provided in this embodiment, in the paper box liner taking and forming device provided in this embodiment, since the rotating shaft 103 can drive the connecting seat 104 to rotate when it rotates, the suction cup 105 connected to the connecting seat 104 can alternately face the discharge port of the hopper 102 and the loading opening of the target paper box 300 during the rotation of the rotating shaft 103. In this way, when the cylinder 106 drives the suction cup 105 to move, the suction cup 105 can pick up the target paper box liner 204 from the hopper 102 and transfer it to the target paper box 300. Since the plate frame 107 forms an annular sidewall 108 for the suction cup 105 to pass through, and since the shape of the annular sidewall 108 is adapted to the shape of the body 201 of the inner lining die-cut sample 200, when the suction cup 105 drives the inner lining die-cut sample 200 through the annular sidewall 108, the supporting edge 202 on the inner lining die-cut sample 200 will form a posture perpendicular to the body 201 under the restriction of the annular sidewall 108, and the paper box die-cut sample will be formed into the target paper box lining 204. Thus, the paper box lining paper taking, forming and boxing device provided in this embodiment can complete the steps of taking paper, forming and boxing the target die-cut sample in one go through the cooperation of the rotating shaft 103, the cylinder 106 and the plate frame 107, which is far superior to the prior art.

[0038] Here, it is understood that when this paper box liner taking paper forming and boxing device is used, it is installed at the corresponding station on the cartoning machine. The target paper box 300 is transported by the conveying device of the cartoning machine to the set position of this paper box liner taking paper forming and boxing device, and can be held in that position to complete the insertion of the target paper box liner 204 into the target paper box 300.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The transfer assembly also includes several forming guide plates 109 arranged around the plate frame 107 on the side opposite to the cylinder 106. The forming guide plates 109 are parallel to the moving direction of the suction cup 105, and all the forming guide plates 109 cooperate to form a forming channel 110 coaxial with the annular sidewall 108 and adapted to the shape of the body 201. According to the structure provided in this embodiment, the forming channel 110 formed by the forming guide plates 109 can make the support edge 202 fold into place more stably, and can also provide good sliding guidance for the support edge 202. In this way, when the cylinder 106 drives the target paper box liner 204 to be loaded into the target paper box 300 through the suction cup 105, the support edge 202 can maintain a stable perpendicular state with the body 201, which is beneficial to further improve the boxing efficiency of the paper box liner taking paper forming and boxing device in this embodiment.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The forming guide plate 109 has an arc-shaped portion 111 on the side away from the frame 107 for abutting against the support edge 202 and facilitating the entry of the support edge 202 into the forming channel 110. According to the structure provided in this embodiment, the arc-shaped portion 111 formed on the forming guide plate 109 makes it easier to fold the support edge 202 and less prone to damage, which is beneficial to further improve the boxing efficiency of the paper box liner taking paper forming and boxing device in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The forming guide plate 109 has a set height in the axial direction of the forming channel 110 so that the forming guide plate 109 can form a gap with the loading opening of the target paper box 300 that is smaller than the width of the support edge 202. According to the structure provided in this embodiment, the gap between the forming guide plate 109 and the target paper box 300 that is smaller than the width of the support edge 202 can ensure that the support edge 202 remains stably perpendicular to the body 201 during the process of loading the target paper box liner 204 into the target paper box 300. The principle is that the outer contour dimension of the target paper box liner 204 after forming is usually slightly smaller than the inner cavity dimension of the target paper box 300. Thus, when the forming guide plate 109 is aligned with the loading opening of the target paper box 300, the gap from the lower edge of the forming guide plate 109 to the edge of the target paper box 300 is smaller than the width of the support edge 202. During the process of the target paper box liner 204 being pushed into the target paper box 300 by the cylinder 106, the rear section of the support edge 202 connected to the body 201 will always be located within the forming guide plate 109 before the front end of the support edge 202 enters the target paper box 300. This allows the support edge 202 to be held in the formed state under the restriction of the forming guide plate 109 (i.e., the support edge 202 always maintains a stable mutually perpendicular state with the body 201), so that the front end of the support edge 202 can smoothly enter the target paper box 300. This is beneficial to further improve the boxing success rate of the paper box liner taking paper forming and boxing device in this embodiment, thereby ensuring boxing efficiency.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The transfer assembly also includes a movable plate 112 whose shape is adapted to the forming channel 110 and can pass through the forming channel 110; multiple suction cups 105 are evenly arranged on the movable plate 112 and connected to the cylinder 106 through the movable plate 112. According to the structure provided in this embodiment, the movable plate 112 that can pass through the forming channel 110 can be used to connect multiple suction cups 105, so that the cylinder 106 can simultaneously drive multiple suction cups 105 to move through the movable plate 112, thereby significantly improving the suction stability of the suction cups 105 on the inner liner die-cut sample 200, which is also conducive to further improving the boxing efficiency of the paper box inner liner paper taking forming and boxing device in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The transfer assembly also includes a U-shaped bracket 113; the bracket 113 is connected to the cylinder 106, and the plate frame 107 is connected to the bracket 113 and connected to the connecting seat 104 through the bracket 113 and the cylinder 106. According to the structure provided in this embodiment, the bracket 113 connected to the cylinder 106 can significantly improve the connection stability between the plate frame 107 and the connecting seat 104, which is beneficial to further improve the boxing efficiency of the paper box liner taking paper forming and boxing device in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The transfer assembly also includes an extension plate 114; the extension plate 114 is axially connected to the opposite sides of the plate frame 107 along the pivot 103, and the front end of the extension plate 114 extends toward the center of the plate frame 107 in the direction of rotation of the plate frame 107 toward the target paper box 300 so that the plate frame 107 can unfold the folded ears 301 on the target paper box 300 through the extension plate 114 during rotation. According to the structure provided in this embodiment, the flap plate 114 provided on the plate frame 107 can unfold the flap 301 on the target paper box 300 in advance before the suction cup 105 and the loading opening of the target paper box 300 are directly aligned. This allows the plate frame 107 to be closer to the target paper box 300, and also allows the support edge 202 and the body 201 to maintain a more stable perpendicular state during the loading of the target paper box liner 204 into the target paper box 300, avoiding interference of the flap 301 on the target paper box 300 with the target paper box liner 204. This is beneficial to further improve the boxing efficiency of the paper box liner taking paper forming and boxing device in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 A stop bar 115 is provided at the discharge port of the hopper 102 for abutting against the support edge 202. The cross-sectional shape of the stop bar 115 is set to be circular to facilitate the support edge 202 to detach from the hopper 102. According to the structure provided in this embodiment, the stop bar 115 provided at the discharge port of the hopper 102 can both confine the inner liner die-cut sample 200 inside the hopper 102 and make the inner liner die-cut sample 200 detach from the hopper 102 more smoothly and less easily damaged during the process of the suction cup 105 picking up the inner liner die-cut sample 200. This is beneficial to further improve the boxing efficiency of the paper box inner liner taking paper forming and boxing device in this embodiment.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The drive mechanism includes a servo motor 116 and a sensor 117 respectively connected to the frame 101. The servo motor 116 is driven to the rotating shaft 103, and the sensor 117 is communicatively connected to the servo motor 116 and is used to detect the rotation angle of the rotating shaft 103. According to the structure provided in this embodiment, the sensor 117, which is communicatively connected to the servo motor 116, can control the servo motor 116 by detecting the rotation angle of the rotating shaft 103. This allows the rotating shaft 103 to rotate within a more precise angle range and makes the suction cup 105 better aligned with the hopper 102 or the target cardboard box 300, thereby further improving the boxing efficiency of the cardboard box liner paper taking, forming and boxing device in this embodiment.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
