Description

Technical Field

[0001] The present application relates to the technical field of carton production auxiliary equipment, and in particular to an auxiliary binding device for cartons. Background Art

[0002] When binding cartons, the staff folds the two sides of the cardboard towards each other until the edges overlap each other, and places the cardboard on the frame of the carton binding machine. At this time, the binding machine drives the cardboard to move to the lower side of the binding part through the conveyor belt. The binding machine drives the binding part to reciprocate in the vertical direction, thereby binding the nails at the overlap to complete the carton binding.

[0003] In the related art, the binding of the overlapping parts of the cartons is achieved by driving the binding part to move back and forth. When the moving speed of the carton driven by the conveyor belt does not match the moving speed of the binding part, the accuracy of the carton binding may be low, which in turn has an adverse effect on the quality of the carton. Summary of the invention

[0004] In order to improve the accuracy of carton binding and reduce the adverse effects on carton quality, the present application provides an auxiliary binding device for carton.

[0005] The present application provides an auxiliary binding device for carton using the following technical solution: An auxiliary binding device for cartons, comprising a baffle installed on the upper side of a conveyor belt and located at a binding part away from a feeding end, the baffle being rotatably connected to the frame, the frame being provided with a rotating component for driving the baffle to rotate, and the frame being provided with an adjusting component for adjusting the distance between the binding part and the baffle.

[0006] By adopting the above technical solution, the distance between the baffle and the binding part is adjusted by the adjustment component, so that the binding nails can be installed in the corresponding position. The conveyor belt on the frame drives the carton to move toward the baffle until it abuts against the lower side of the baffle. At this time, the binding part is driven to bind, and the rotating component drives the baffle to rotate, thereby lifting the lower side of the baffle, which is convenient for the carton to pass through the lower side of the baffle, thereby improving the accuracy of carton binding and reducing the adverse effects on carton quality without affecting work efficiency.

[0007] Optionally, the rotating assembly includes a driving frame located on the upper side of the baffle, the upper side of the baffle is rotatably connected to the end of the driving frame, the driving frame is slidably connected to the frame body, the end of the driving frame away from the baffle is hinged with a first hinged rod, the side of the baffle close to the first hinged rod is hinged with a second hinged rod, the ends of the first hinged rod and the second hinged rod close to each other are hinged to each other and rotatably connected with a third hinged rod, and the driving frame is provided with a rotating part for driving the third hinged rod to move.

[0008] By adopting the above technical solution, the rotating member drives the third hinged rod to move in the direction close to the second hinged rod, thereby driving the second hinged rod to move and rotate in the direction away from the first hinged rod, until the baffle is pushed to rotate to a direction perpendicular to the length direction of the frame, which is convenient for limiting the end of the carton. When the carton continues to move, the rotating member drives the third hinged rod to move in the direction away from the second hinged rod, thereby driving the end of the second hinged rod through the first hinged rod to pull the baffle to rotate in the direction close to the third hinged rod, which is convenient for lifting the lower side of the baffle, thereby improving the accuracy of carton binding and reducing the adverse effects on carton movement.

[0009] Optionally, the adjustment assembly includes a rotating screw passing through the drive frame and threadedly connected to the drive frame, the rotating screw is rotatably connected to the frame body, and a first motor rotatably connected to the frame body is installed at one end of the rotating screw.

[0010] By adopting the above technical solution, the first motor drives the rotating screw to rotate, thereby driving the driving frame to drive the baffle to move along the length direction of the rotating screw, which is convenient for adjusting the distance between the baffle and the binding part, thereby adapting to the binding requirements of cartons of different specifications and improving applicability.

[0011] Optionally, the rotating member includes a disk located at one end of the third hinged rod away from the second hinged rod and rotatably connected to the driving frame, and the end of the third hinged rod is hinged to the eccentric portion of the disk.

[0012] By adopting the above technical solution, when the baffle is driven to block the carton, the driving disc is rotated until the end of the third hinged rod is located on the lower side of the disc axis. At this time, the second hinged rod pushes the baffle to rotate perpendicular to the length direction of the frame, which is convenient for limiting the carton. When the carton continues to move, the disc is rotated until the upper end of the third hinged rod is located on the upper side of the disc axis, so that the baffle is driven to rotate and lift up through the first hinged rod and the second hinged rod, which facilitates the movement of the carton, thereby improving the accuracy of carton binding while reducing the adverse effects on carton movement.

[0013] Optionally, the lower side of the frame is rotatably connected to a rotating roller arranged along the width direction of the frame, and a control motor is installed at one end of the mounting roller. The frame is provided with an output end and a receiving end which are arranged along the height direction of the frame and cooperate with each other. The carton moves and passes through the gap between the output end and the receiving end. The receiving end is radio-connected to a control host, the control motor is radio-connected to the control host, and a connecting piece is provided between the control motor and the disc to connect the two.

[0014] By adopting the above technical solution, when the end of the carton moves to the upper side of the rotating roller, the receiving end blocks the signal from the output end. At this time, the control host drives the control motor to drive the rotating roller to rotate, and the control motor drives the disc to rotate through the connecting piece, so as to control the disc to rotate and drive the baffle to block the carton. At the same time, when the moving distance of the carton is adapted to the distance between two adjacent binding nails, the control motor drives the baffle to rotate through the connecting piece again and abuts against the carton, which is convenient for binding, further improving the accuracy of carton binding and reducing the adverse effects on carton quality.

[0015] Optionally, the connecting member includes a first gear fixedly connected to the end of the rotating roller, a second gear with a diameter larger than that of the first gear is meshed on one side of the first gear, and a first belt is installed between the second gear and the disc.

[0016] By adopting the above technical solution, the first gear and the second gear are meshed, and the diameter of the second gear is larger than the diameter of the first gear. Therefore, while the disc is driven to rotate by the first gear, the second gear and the first belt, the rotation speed of the rotating roller and the disc matches the moving speed of the carton, thereby further improving the accuracy of carton binding and reducing the adverse effects on the quality of the carton.

[0017] Optionally, both sides of the frame are provided with limit plates arranged along the height direction of the frame, the limit plates are located on the side of the rotating roller away from the baffle and are slidably connected to the frame in a direction approaching each other, and a sliding part is provided on the frame to drive the limit plates to slide.

[0018] By adopting the above technical solution, when the carton moves and passes between the limit plates, the sliding member drives the limit plates to move in the direction of approaching each other until they abut against the side walls of the carton, thereby facilitating the adjustment of the position of the carton so that the carton is located in the middle of the frame, reducing the possibility of the carton falling during the movement.

[0019] Optionally, the sliding member includes hydraulic cylinders installed on the frame and corresponding to the limit plates one by one, and the hydraulic cylinders are all located on the side of the limit plates that are away from each other.

[0020] By adopting the above technical solution, the limit plates are driven by the hydraulic cylinder to move in the direction of approaching each other and adjust the position of the carton. At the same time, it is convenient to adjust the moving distance of the limit plates according to cartons of different specifications, thereby further improving applicability.

[0021] Optionally, both sides of the frame are fixedly connected to fixed frames, one end of the hydraulic cylinder away from the limit plate is slidably connected to the corresponding fixed frame, the ends of the hydraulic cylinders away from each other are hinged with a fourth hinged rod, the end of the fourth hinged rod away from the hydraulic cylinder is hinged with a fifth hinged rod, the other end of the fifth hinged rod is inclined upward and hinged to the upper end of the fixed frame, the hinged ends between the fourth hinged rod and the fifth hinged rod are inserted and slidably connected with the same connecting rod slidably connected to the frame, and the frame is provided with a driving member that drives the connecting rod to move in a direction close to the limit plate.

[0022] By adopting the above technical solution, when the carton is not in contact with the rotating roller, the hydraulic cylinder drives the limit plate to move in the direction of approaching each other and adjusts the carton to be located on the center line of the frame. After the adjustment is completed, the hydraulic cylinder drives the limit plate to move in the direction of moving away from each other. At this time, the distance that the hydraulic cylinder drives the limit plate to move is adapted to the distance that the driving member drives the limit plate to move. When the baffle abuts against the upper side of the carton, the driving member drives the connecting rod to move upward and drives the limit plate through the fourth hinged rod, the fifth hinged rod and the hydraulic cylinder to move in the direction of approaching each other until it abuts against the side wall of the carton, which is convenient for binding, further improving the accuracy of carton binding and reducing the adverse effects on the quality of the carton.

[0023] Optionally, a driving rod is provided on the lower side of the connecting rod, and the lower end of the driving rod is bent into a right angle. The driving member includes a reciprocating screw that passes through one bent end of the driving rod and is threadedly connected to the driving rod. The reciprocating screw is rotatably connected to the frame body, and a first bevel gear is fixedly connected to the end of the reciprocating screw, a second bevel gear is meshed with one side of the first bevel gear, and a second belt is installed between the second bevel gear and the end of the rotating roller.

[0024] By adopting the above technical solution, when the rotating roller rotates, the second bevel gear is driven to rotate through the second belt. At this time, the first bevel gear rotates with the second bevel gear and drives the reciprocating screw to rotate, thereby driving the connecting rod to reciprocate through the driving rod, so that when the baffle plate abuts against the upper side of the carton, the limit plate is driven to contact the side wall of the carton, thereby further improving the accuracy of stapling and reducing the adverse effects on the quality of the carton.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the baffle is driven to block the carton, the driving disc rotates until the end of the third hinge rod is located at the lower side of the disc axis. At this time, the second hinge rod pushes the baffle to rotate perpendicular to the length direction of the frame, which is convenient for limiting the carton. When the carton continues to move, the disc rotates until the upper end of the third hinge rod is located at the upper side of the disc axis, so that the baffle is driven to rotate and lift up through the first hinge rod and the second hinge rod, which is convenient for moving the carton; 2. When the end of the carton moves to the upper side of the rotating roller, the receiving end blocks the signal of the receiving output end. At this time, the control host drives the control motor to drive the rotating roller to rotate, and the control motor drives the disc to rotate through the connecting piece, so as to control the disc to rotate and drive the baffle to block the carton. At the same time, when the moving distance of the carton is adapted to the distance between two adjacent binding nails, the control motor drives the baffle to rotate through the connecting piece again and abuts against the carton, which is convenient for binding, further improving the accuracy of carton binding and reducing the adverse effects on carton quality; 3. When the rotating roller rotates, the second bevel gear is driven to rotate through the second belt. At this time, the first bevel gear rotates with the second bevel gear and drives the reciprocating screw to rotate, thereby driving the connecting rod to reciprocate through the driving rod, so that when the baffle plate abuts against the upper side of the carton, the limit plate is driven to contact the side wall of the carton, thereby further improving the accuracy of stapling and reducing the adverse effects on the quality of the carton.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses an auxiliary binding device for cartons. Example 1

[0035] Reference Figure 1 and Figure 2 A carton auxiliary binding device includes a baffle plate 2 located on the upper side of a frame 1, a plurality of conveyor belts (not shown in the figure) arranged along the length direction of the frame 1 are installed on the upper side of the frame 1, and a binding part (not shown in the figure) located on the side of the baffle plate 2 close to the feeding end is installed on the upper side of the frame 1. The baffle plate 2 can rotate with its upper side edge as the axis, and a rotating component 3 for driving the baffle plate 2 to rotate and an adjusting component 4 for adjusting the distance between the baffle plate 2 and the binding part are provided on the frame 1.

[0036] Reference Figure 2 and Figure 3 The rotating assembly 3 includes a driving frame 31 located on the upper side of the baffle 2 and arranged along the length direction of the frame body 1. The upper side of the frame body 1 is provided with a stabilizing frame 11 arranged along the width direction of the frame body 1 and located on the side of the end of the driving frame 31 close to the baffle 2. Both ends of the stabilizing frame 11 are fixedly connected to the upper side of the frame body 1. The lower side of the stabilizing frame 11 does not contact the upper side of the frame body 1, and the end of the driving frame 31 close to the baffle 2 passes through the lower side of the stabilizing frame 11. The side of the stabilizing frame 11 close to the feeding end of the frame body 1 is fixedly connected with a mounting frame 12. Two guide rods 41 parallel to the length direction of the frame body 1 are penetrated and fixedly connected inside the mounting frame 12. The upper side of the driving frame 31 is simultaneously sleeved on the two guide rods 41 and slidably connected with the guide rods 41.

[0037] Reference Figure 2 and Figure 3The adjusting assembly 4 includes a rotating screw 42 located between the two guide rods 41 and passing through and threadedly connected to the upper side of the driving frame 31. The rotating screw 42 is rotatably connected to the mounting frame 12, and a first motor 43 fixedly connected to the mounting frame 12 is installed at one end of the rotating screw 42 close to the feeding end of the frame body 1.

[0038] The upper side of the baffle 2 is inserted into the end of the driving frame 31 and is rotatably connected to the driving frame 31. The driving frame 31 is hinged with a first hinge rod 32 at one end away from the baffle 2 and close to the baffle 2. The baffle 2 is hinged with a second hinge rod 33 located at the lower side of its own rotation axis at one side close to the first hinge rod 32. A hinge shaft 34 is provided between the first hinge rod 32 and the second hinge rod 33, which passes through one end of the first hinge rod 32 and the second hinge rod 33 that are close to each other. The first hinge rod 32 and the second hinge rod 33 are both rotatably connected to the hinge shaft 34. The end of the hinge shaft 34 is sleeved and rotatably connected with a third hinge rod 35 arranged in the vertical direction, and a rotating member 36 is provided on the driving frame 31 to drive the third hinge rod 35 to move and rotate in the vertical direction.

[0039] The first motor 43 drives the rotating screw 42 to rotate and causes the driving frame 31 to drive the baffle 2 to move along the length direction of the guide rod 41, so as to adjust the distance between the baffle 2 and the binding part. The conveyor belt on the frame 1 drives the carton to move in the direction close to the baffle 2. The rotating member 36 drives the third hinged rod 35 to move in the direction close to the second hinged rod 33, thereby driving the second hinged rod 33 to move and rotate in the direction away from the first hinged rod 32 until the baffle 2 is pushed to rotate vertically, so as to facilitate the carton to abut against the lower side of the baffle 2. At this time, the binding part is driven to bind. When the carton continues to move, the rotating member 36 drives the third hinged rod 35 to move in the direction away from the second hinged rod 33, thereby driving the end of the second hinged rod 33 through the first hinged rod 32 to pull the baffle 2 to rotate and lift in the direction close to the third hinged rod 35, so as to facilitate the passage of the carton.

[0040] The rotating member 36 includes a vertical disk 361 rotatably connected to the upper side of the driving frame 31, and the upper side of the third hinge rod 35 is hinged to the eccentric part of the disk 361. When the baffle 2 blocks the carton, the upper end of the third hinge rod 35 is located below the axis of the disk 361. When the lower side of the baffle 2 is tilted and lifted toward the direction close to the first hinge rod 32, the upper end of the third hinge rod 35 is located above the axis of the disk 361. In the embodiment of the present application, the upper side of the driving frame 31 is fixedly connected to a second motor 362 installed at the axis of the disk 361.

[0041] The second motor 362 drives the disk 361 to rotate until the end of the third hinged rod 35 is located on the lower side of the axis of the disk 361. At this time, the second hinged rod 33 pushes the baffle 2 to rotate vertically, which is convenient for limiting the carton. When the carton continues to move, the second motor 362 drives the disk 361 to rotate until the upper end of the third hinged rod 35 is located on the upper side of the axis of the disk 361, which is convenient for driving the baffle 2 to rotate and lift through the first hinged rod 32 and the second hinged rod 33, so as to facilitate the movement of the carton.

[0042] The implementation principle of Example 1 is: drive the carton to move in the direction close to the baffle 2, and push the baffle 2 to rotate to vertical through the first hinge rod 32, the second hinge rod 33 and the third hinge rod 35, so that the carton is convenient for abutting against the lower side of the baffle 2. At this time, the binding part is driven to bind. When the carton continues to move, the baffle 2 is driven to rotate and lift in the direction close to the third hinge rod 35, so as to facilitate the passage of the carton and improve the binding accuracy. Example 2

[0043] Reference Figure 4 and Figure 5 The difference between this embodiment and the embodiment 1 is that the upper side of the frame 1 is rotatably connected to a rotating roller 5 arranged along the width direction of the frame 1, and the end of the rotating roller 5 is installed with a control motor 51 fixedly connected to the frame 1. The upper side of the frame 1 is installed with an upward receiving end (not shown in the figure), and the lower side of the mounting frame 12 is installed with an output end (not shown in the figure) adapted to the receiving end, and the output end is radio-connected to a control host (not shown in the figure). The control motor 51 is radio-connected to the control host, and a connecting piece 6 connecting the control motor 51 and the disk 361 is provided between the control motor 51 and the disk 361.

[0044] Reference Figure 4 and Figure 5 The connecting member 6 includes a first gear 61 fixedly connected to the end of the rotating roller 5, a second gear 62 with a diameter larger than that of the first gear 61 is meshed on one side of the first gear 61, a connecting shaft 63 is fixedly connected to the axis of the disk 361 near the second gear 62, and a first belt 64 connecting the connecting shaft 63 and the second gear 62 is installed between the two.

[0045] When the end of the carton moves to the upper side of the rotating roller 5, the signal from the receiving end to the output end is blocked, and the control host drives the control motor 51 to drive the rotating roller 5 to rotate, and the control motor 51 drives the disc 361 to rotate through the first belt 64, the first gear 61, the second gear 62 and the connecting shaft 63, so as to control the rotation of the disc 361 and drive the baffle 2 to block the carton. At the same time, when the moving distance of the carton is adapted to the distance between two adjacent binding nails, the control motor 51 drives the baffle 2 to rotate again and abut against the carton, which is convenient for binding and improves the accuracy of carton binding.

[0046] The first gear 61 and the second gear 62 are meshed, and the diameter of the second gear 62 is larger than the diameter of the first gear 61. Therefore, while the disc 361 is driven to rotate by the first gear 61, the second gear 62 and the first belt 64, the rotation speed of the rotating roller 5 and the disc 361 matches the moving speed of the carton, further improving the accuracy of carton binding.

[0047] Reference Figure 5 and Figure 6 The upper side of the frame 1 is slidably connected to two vertical limit plates 7 which are arranged opposite to each other and are located on the side of the binding part close to the feeding end of the frame 1. The upper side of the frame 1 is provided with a sliding member for driving the limit plates 7 to move in a direction close to or away from each other. In the embodiment of the present application, a hydraulic cylinder 71 is arranged to correspond to the limit plates 7 one by one and is located on the side of the limit plates 7 which are away from each other. The telescopic rods of the hydraulic cylinder 71 are all facing the corresponding limit plates 7 and are fixedly connected to the limit plates 7.

[0048] Both sides of the frame 1 are fixedly connected with vertical fixing frames 72 corresponding to the limit plates 7, and the ends of the hydraulic cylinders 71 that are away from each other are slidably connected to the upper ends of the corresponding fixing frames 72. The lower sides of the ends of the hydraulic cylinders 71 that are away from each other are hinged with fourth hinged rods 73 that are tilted downward and away from each other, and the ends of the fourth hinged rods 73 that are away from the hydraulic cylinders 71 are hinged with fifth hinged rods 74 that are tilted upward and away from each other, and the ends of the fifth hinged rods 74 that are away from the fourth hinged rods 73 are hinged with the upper ends of the fixing frames 72 and the side away from the hydraulic cylinders 71.

[0049] The fourth hinge rod 73 and the fifth hinge rod 74 are sleeved and rotatably connected to the sliding seat 75 at one end close to each other. The sliding seat 75 is penetrated and slidably connected with the same horizontal connecting rod 76, which passes through the frame 1 and is slidably connected to the frame 1. A vertical driving rod 77 is fixedly connected to the middle part of the lower side of the connecting rod 76. The lower end of the driving rod 77 is bent at a right angle near the end of the rotating roller 5. The rotating roller 5 is provided with a driving member 78 that drives the driving rod 77 to move in the vertical direction.

[0050] When the carton is not in contact with the rotating roller 5, the hydraulic cylinder 71 drives the limit plate 7 to move in the direction of approaching each other and adjusts the carton to be located on the center line of the frame 1. At the same time, it is convenient to adjust the moving distance of the limit plate 7 to approach each other according to cartons of different specifications. After the adjustment is completed, the hydraulic cylinder 71 drives the limit plate 7 to move in the direction of moving away from each other. At this time, the distance that the hydraulic cylinder 71 drives the limit plate 7 to move is adapted to the distance that the driving member 78 drives the limit plate 7 to move. When the baffle 2 abuts against the upper side of the carton, the driving member 78 drives the connecting rod 76 to move upward and drives the limit plate 7 to move in the direction of approaching each other through the fourth hinged rod 73, the fifth hinged rod 74 and the hydraulic cylinder 71 until it abuts against the side wall of the carton for easy binding.

[0051] The driving member 78 includes a vertical reciprocating screw 781 that passes through one end of the bent driving rod 77 and is threadedly connected to the driving rod 77. The reciprocating screw 781 is rotatably connected to the frame 1. A horizontal first bevel gear 782 is fixedly connected to the end of the reciprocating screw 781. A vertical second bevel gear 783 rotatably connected to the frame 1 is meshed on one side of the first bevel gear 782. A horizontal driving shaft 784 is fixedly connected to the axis of the second bevel gear 783 away from the first bevel gear 782, and a second belt 785 is installed between the driving shaft 784 and the rotating roller 5.

[0052] When the rotating roller 5 rotates, the driving shaft 784 and the second bevel gear 783 are driven to rotate through the second belt 785. At this time, the first bevel gear 782 rotates with the second bevel gear 783 and drives the reciprocating screw 781 to rotate, thereby driving the connecting rod 76 to reciprocate through the driving rod 77, so that when the baffle 2 abuts against the upper side of the carton, the limit plate 7 is driven to contact the side wall of the carton, thereby further improving the accuracy of stapling.

[0053] When the carton is on the rotating roller 5, the control motor 51 is continuously rotated, so as to facilitate driving the rotating roller 5, the disk 361 and the reciprocating screw 781 to rotate continuously, thereby making the baffle 2 continuously swing along its own rotation axis, and the limit plate 7 reciprocates in the direction of approaching or moving away. After binding the first binding nail on the carton, when the moving distance of the carton is equal to the distance between two adjacent binding nails on the carton, the second binding nail needs to be bound. At this time, the baffle 2 is first rotated to vertical and then tilted, and the limit plate 7 is first moved to contact with the side wall of the carton and then reset, so as to facilitate binding and accurately control the distance between two adjacent binding nails on the carton until the binding is completed.

[0054] The implementation principle of Example 2 is: when the carton is not in contact with the rotating roller 5, the hydraulic cylinder 71 drives the limit plate 7 to move and adjust the carton to the center line of the frame 1. After the adjustment is completed, the hydraulic cylinder 71 drives the limit plate 7 to move in the direction away from each other. At this time, the distance that the hydraulic cylinder 71 drives the limit plate 7 to move is consistent with the distance that the driving member 78 drives the limit plate 7 to move. When the baffle 2 abuts against the upper side of the carton, the rotating roller 5 rotates and drives the baffle 2 to gradually rotate to vertical, and the connecting rod 76 moves upward and drives the limit plate 7 to move in the direction of approaching each other through the fourth hinged rod 73, the fifth hinged rod 74 and the hydraulic cylinder 71 until it abuts against the side wall of the carton for easy binding.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
