Description

Technical Field

[0001] The invention relates to the technical field of material flipping and conveying, and in particular to an automatic flanging and conveying device for a packaging box. Background Art

[0002] In the manufacturing and sales process of various products on the market, packaging boxes are inseparable. On the production line, packaging boxes are usually in the form of folded plates, which are folded and unfolded manually or automatically on the transmission equipment to make them appear block-shaped.

[0003] During the current packaging process, both sides of the packaging box need to be sealed with tape, so the packaging box also needs to be turned over and flanged. However, the traditional operation method is mostly manual turning or automatic clamping and turning, which wastes a lot of labor. On the other hand, the auxiliary turning of the mechanical clamping component may leave an imprint on the surface of the paper packaging box, affecting the aesthetic effect of the packaging box.

[0004] Therefore, how to provide a packaging box automatic flanging transmission device is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] One purpose of the present invention is to provide an automatic flanging transmission device for packaging boxes. The present invention provides a new flanging transmission effect for packaging boxes, which effectively replaces labor output, and compared with traditional mechanical automatic clamping devices, it can prevent marks from being left on the surface of the packaging box.

[0006] According to an embodiment of the present invention, an automatic flanging transmission device for a packaging box includes a transmission component, which includes a machine platform, a first conveyor belt, two sets of second conveyor belts and a discharge conveyor belt. The first conveyor belt and the second conveyor belt are both arranged on the machine platform for transmission in the same direction. The two sets of second conveyor belts are respectively located on both sides of the first conveyor belt. The length of the first conveyor belt is greater than the length of the second conveyor belt. The tops of the first conveyor belt and the second conveyor belt jointly support the main body of the packaging box. The discharge conveyor belt is located on a movable platform on one side of the machine platform. The movable platform drives the discharge conveyor belt to move left and right on one side of the machine platform and align with the bottom of the first conveyor belt.

[0007] A No. 1 air nozzle is movably arranged at the top of the machine near the first conveyor belt through two groups of belt separation mechanisms. The No. 1 air nozzle is connected to the blower through a connecting pipe to provide downward wind pressure for the main body of the packaging box;

[0008] A flipping mechanism is arranged on one side of the machine, and the flipping mechanism comprises a transmission motor and two sets of placement plates, and the two sets of placement plates are respectively fixed on both sides of the main connecting rod, and the main connecting rod is transmission-connected to the output shaft of the transmission motor, and the No. 2 air nozzle and the No. 3 air nozzle are respectively fixed on the upper and lower sides of the placement plate, and the No. 2 air nozzle and the No. 3 air nozzle are distributed at a right angle therebetween, and the transmission motor drives the No. 2 air nozzle and the No. 3 air nozzle to flip at right angles on both sides of the first conveyor belt.

[0009] Furthermore, the distance between the two groups of No. 3 air nozzles is relatively larger than the width of the packaging box body, and the horizontal height distance between the discharge conveyor belt and the first conveyor belt is larger than the length of the packaging box body.

[0010] Furthermore, the transmission motor is fixed on the surface of the machine platform, the output shaft of the transmission motor is fixed with a single tooth, the upper part of the single tooth is meshed with an engaging tooth, and the engaging tooth directly drives the placement plate to rotate above the machine platform through a main connecting rod.

[0011] Furthermore, one side of the engaging tooth engages the side tooth through a connecting tooth, a bevel gear group is fixed on the surface of the side tooth, and the side tooth is transmission-connected to the air distribution assembly through the bevel gear group, and the air distribution assembly is respectively connected to the blower, the second air nozzle and the third air nozzle.

[0012] Furthermore, the gas distribution assembly also includes a cylinder and a block. The block moves up and down inside the cylinder through the protruding pin blocks on both sides of the top. A conical opening is opened at the bottom of the inner surface of the cylinder, and a conical block is set at the bottom of the block. The oblique angle of the conical block matches the conical opening.

[0013] Furthermore, a transmission screw is connected to the upper inner part of the blocking block by a thread, the top of the transmission screw is fixed to the bevel gear group, the transmission screw is connected to the side gear transmission through the bevel gear group, a No. 3 air port is opened at the bottom of the cylinder, the No. 3 air port is connected to the No. 3 air nozzle through a connecting pipe, an air inlet is opened above the conical port, the air inlet is connected to the blower through a connecting pipe, a No. 2 air port is opened above the cylinder, and the No. 2 air port is connected to the No. 2 air nozzle through a connecting pipe.

[0014] Furthermore, the take-off mechanism includes an electric slider and a stand, the stand is fixed on the electric slider, the electric slider is slidably arranged on the surface of the slide rail, a limiting slide groove is provided inside the stand, the limiting slide slider slides up and down on the inner wall of the limiting slide groove, and the No. 1 air nozzle is fixedly connected to the limiting slide slider through a connecting rod.

[0015] Furthermore, one side of the limit slider is rotatably connected to a folding frame through a protruding pin, the top of the folding frame is movably connected to the limit slider, and the bottom of the folding frame is rotatably connected to one side of the electric slider through an axis hole.

[0016] Furthermore, a transmission tooth is fixed at the center of the rotation circle at the bottom of the folding frame, one side of the transmission tooth engages with the main tooth, the main tooth engages with the horizontal tooth rod on the surface of the machine, and there is a certain relative distance between the transmission tooth and the horizontal tooth rod.

[0017] Furthermore, the height of the inner wall of the limiting slide groove is greater than the height dimension of the packaging box body, and a damping plate is also arranged between the main teeth and the electric slider.

[0018] The beneficial effects of the present invention are:

[0019] The present invention sets up a transmission component, and the first conveyor belt and two groups of second conveyor belts respectively correspond to the middle position of the supporting packaging box body and the two side cover plates. When the packaging box body is taken away from the second conveyor belt by the first conveyor belt, one side of the packaging box body begins to separate from the first conveyor belt, thereby realizing a 90-degree flipping effect of the packaging box body at this point. Then the movable table drives the discharging conveyor belt close to the first conveyor belt, providing support at the bottom of the packaging box body, and utilizing the blowing effect of the No. 2 air nozzle to blow the area above the packaging box body, thereby realizing the automatic flipping operation of the packaging box body. Compared with traditional manual operation and mechanical clamping operation, it has the effect of reducing labor output and leaving no marks on the surface of the packaging box body.

[0020] The present invention provides a flipping mechanism. When one side of the packaging box body begins to separate from the first conveyor belt, the packaging box body will tend to fall downward under the action of gravity. At this time, the No. 3 air nozzle blows air into the cavity below the packaging box body to prevent the packaging box body from falling. After being driven, the transmission motor can drive the main connecting rod and the mounting plate to rotate through the engagement of the single tooth and the bite tooth. At the same time, the blowing direction of the No. 3 air nozzle changes, and the packaging box body slowly swings downward on one side of the first conveyor belt, thereby preventing the packaging box body from falling off the first conveyor belt at the moment of separation from the first conveyor belt.

[0021] The present invention provides an air distribution component, and the engaging teeth drive the main connecting rod to rotate, and at the same time drive the side teeth and the bevel gear group to rotate through the connecting teeth. The bevel gear group directly fixes the transmission screw. After the transmission screw rotates, the blocking block is restricted by the sliding of the convex pin block inside the cylinder and moves downward. At this time, the cone block and the conical mouth at the bottom of the blocking block are close to each other, and the gas pressure injected into the cylinder by the blower through the air inlet gradually decreases from the port of the No. 3 air port. In this way, the blowing pressure that the No. 3 air nozzle can provide to the packaging box body is gradually reduced, which prevents the No. 3 air nozzle from blowing too much and causing the packaging box body to separate from the first conveyor belt, effectively improving the practical effect.

[0022] The present invention provides a No. 2 air nozzle. When the No. 3 air nozzle is driven by the transmission motor to rotate to ninety degrees, the blowing port of the No. 2 air nozzle is directly opposite to the side panel above the packaging box body, and at the same time, the cone block is completely fitted with the cone-shaped opening, and the gas sent into the cylinder by the air inlet flows out from the No. 2 air port on the top. The instantaneous blowing effect of the No. 2 air nozzle will blow the entire flange of the packaging box body to fall on the discharge conveyor belt, thereby completing the overall flipping operation, thereby improving the reliability of the device.

[0023] The present invention provides a belt-off mechanism. When the packaging box body is about to separate from the first conveyor belt, the electric slider is driven to move to one side on the slide rail surface. At this time, the main meshing teeth on one side of the electric slider mesh with the horizontal meshing rod. The rotation effect will drive the folding frame to retract through the meshing of the transmission teeth. The limiting slider on the top of the folding frame slides downward in the limiting slide groove, and simultaneously drives the No. 1 air nozzle to move downward through the connecting rod, so that the No. 1 air nozzle is close to the side panel on one side of the packaging box body. This is because the No. 1 air nozzle blows air downward through the blower. Under the action of air pressure, the fitting effect of the packaging box body and the first conveyor belt can be effectively guaranteed, and the phenomenon of the packaging box body falling off the first conveyor belt due to the blowing of the No. 3 air nozzle can be further prevented.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0038] refer to Figure 1-Figure 9 , including a transmission component 1, the transmission component 1 includes a machine table 11, a first conveyor belt 12, two sets of second conveyor belts 13 and a discharge conveyor belt 14, the first conveyor belt 12 and the second conveyor belt 13 are both arranged on the machine table 11 for transmission in the same direction, the two sets of second conveyor belts 13 are respectively located on both sides of the first conveyor belt 12, the length of the first conveyor belt 12 is greater than the length of the second conveyor belt 13, the tops of the first conveyor belt 12 and the second conveyor belt 13 jointly support the packaging box body 3, the discharge conveyor belt 14 is located on a movable table 2 on one side of the machine table 11, and the movable table 2 drives the discharge conveyor belt 14 to move left and right on one side of the machine table 11 and align with the bottom of the first conveyor belt 12;

[0039] A first air nozzle 5 is movably provided at the top of the machine platform 11 near the upper position of the first conveyor belt 12 through two groups of belt separation mechanisms 4. The first air nozzle 5 is connected to the blower 69 through a connecting pipe to provide downward wind pressure to the packaging box body 3;

[0040] A flipping mechanism 6 is arranged on one side of the machine 11, and the flipping mechanism 6 includes a transmission motor 61 and two sets of placement plates 65. The two sets of placement plates 65 are respectively fixed on both sides of the main connecting rod 64, and the main connecting rod 64 is transmission-connected to the output shaft of the transmission motor 61. The No. 2 air nozzle 7 and the No. 3 air nozzle 8 are respectively fixed on the upper and lower sides of the placement plate 65, and the No. 2 air nozzle 7 and the No. 3 air nozzle 8 are distributed at a right angle thereto. The transmission motor 61 drives the No. 2 air nozzle 7 and the No. 3 air nozzle 8 to flip at right angles on both sides of the first conveyor belt 12.

[0041] In this embodiment, the first conveyor belt 12 is used to support the side panels at the middle section of the packaging box body 3 and the front and rear sides, and the second conveyor belt 13 is used to support the side panels on the left and right sides of the packaging box body 3. The first conveyor belt 12 and the second conveyor belt 13 move forward synchronously to realize the transmission of the packaging box body 3, and the length of the first conveyor belt 12 is greater than the length of the second conveyor belt 13. After reaching the specified position, the side panels on the left and right sides of the packaging box body 3 are separated from the second conveyor belt 13 and move forward under the support of other structures to prevent the two groups of side panels from sagging. This can be solved by setting convex warping structures on both sides of the first conveyor belt 12, and then After the packaging box body 3 reaches the maximum position on one side of the first conveyor belt 12, the first conveyor belt 12 continues to drive to cause the side plate in front of the packaging box body 3 to separate from the first conveyor belt 12, and then the internal cavity of the packaging box body 3 contacts the end position of the first conveyor belt 12, and the packaging box body 3 presents a flipping posture until the packaging box body 3 is completely vertical by 90 degrees. At this time, the movable platform 2 drives the top discharge conveyor belt 14 to move below the packaging box body 3 and fit the side plate below the packaging box body 3, and cooperates with the blowing of the No. 2 air nozzle 7 to realize the flipping and flanging operation of the packaging box body 3 on the surface of the discharge conveyor belt 14;

[0042] In order to improve the actual use effect, a No. 1 air nozzle 5 is arranged above the top of the machine 11 near the first conveyor belt 12, and the two groups of belt separation mechanisms 4 can drive the No. 1 air nozzle 5 to move up and down above the first conveyor belt 12, so that the No. 1 air nozzle 5 moves to the top of the packaging box body 3 until the packaging box body 3 is close to the end position of the first conveyor belt 12 and then moves downward to the side plate position behind the packaging box body 3. At this time, the No. 1 air nozzle 5 blows air to the side plate of the packaging box body 3, and the air pressure will make the side plate of the packaging box body 3 fit together with the surface of the first conveyor belt 12 to prevent the packaging box body 3 from falling off during the flipping process;

[0043] The blowing direction vectors of the No. 2 air nozzle 7 and the No. 3 air nozzle 8 form an angle of ninety degrees. In this way, when the blowing port of the No. 3 air nozzle 8 is facing upward, the blowing port of the No. 2 air nozzle 7 is aimed at the rear. At the moment when the front cavity of the packaging box main body 3 is separated from the first conveyor belt 12, the packaging box main body 3 has a tendency to flip downward. At this time, the No. 3 air nozzle 8 blows air to provide an air pressure support effect, and cooperates with the No. 1 air nozzle 5 to stabilize the shape of the packaging box main body 3. Then the transmission motor 61 drives the placement plate 65, the No. 2 air nozzle 7 and the No. 3 air nozzle 8 to flip at a low speed. The blowing direction of the No. 3 air nozzle 8 gradually changes, and the packaging box main body 3 also A low-speed flipping will occur, and the placement plate 65 will be flipped continuously to achieve a flipping angle of 180 degrees. At this time, the blowing port of the No. 2 air nozzle 7 is aligned with the two sides of the cavity above the packaging box body 3, and the blowing port of the No. 3 air nozzle 8 is downward, disconnecting the blowing effect of the No. 1 air nozzle 5. The belt-away mechanism 4 drives the No. 1 air nozzle 5 to move upward to prevent it from hindering the flipping of the packaging box body 3. Then the No. 2 air nozzle 7 blows air. The air pressure will cause a lateral force to be applied to the upper part of the packaging box body 3, thereby cooperating with the support of the discharge conveyor belt 14 to realize the flanging operation. The whole does not need to be mechanically clamped to prevent the occurrence of clamping marks.

[0044] refer to Figure 3 and Figure 8 The distance between the two groups of No. 3 air nozzles 8 is relatively larger than the width distance of the packaging box body 3 , and the horizontal height distance between the discharge conveyor belt 14 and the first conveyor belt 12 is larger than the length distance of the packaging box body 3 .

[0045] In this embodiment, the relative distance of the No. 3 air nozzle 8 is greater than the width of the packaging box body 3, which means that during the blowing process of the No. 3 air nozzle 8, most of the airflow will act on the side panels on the left and right sides of the packaging box body 3 to prevent the airflow from acting entirely on the cavity of the packaging box body 3 and causing the packaging box body 3 to move. The relative height dimension between the discharge conveyor belt 14 and the first conveyor belt 12 is greater than the length of the packaging box body 3, which means that the discharge conveyor belt 14 can move normally to the bottom of the packaging box body 3, and after the No. 2 air nozzle 7 is blown, the packaging box body 3 has a certain space for flipping activities.

[0046] refer to Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig. 9, the transmission motor 61 is fixed on the surface of the machine 11, the output shaft of the transmission motor 61 is fixed with a single tooth 62, the upper part of the single tooth 62 is meshed with a bite tooth 63, and the bite tooth 63 directly drives the placement plate 65 to rotate above the machine 11 through the main connecting rod 64. One side of the bite tooth 63 is meshed with the side teeth 66 through the connecting teeth, and the surface of the side teeth 66 is fixed with a bevel gear group 67, and the side teeth 66 are connected to the air distribution assembly 68 through the bevel gear group 67. The air distribution assembly 68 is connected to the blower 69, the second air nozzle 7 and the third air nozzle 8 respectively. The air distribution assembly 68 also includes a cylinder 681 and a block 682. The block 682 moves up and down inside the cylinder 681 through the convex pin blocks 686 on both sides of the top. A conical opening 684 is opened at the bottom of the inner surface of the cylinder 681, and a conical block 685 is set at the bottom of the block 682. The oblique angle of the conical block 685 matches the conical opening 684. The upper part of the blocking block 682 is threadedly connected to the transmission screw 683, the top of the transmission screw 683 is fixed to the bevel gear group 67, the transmission screw 683 is transmission-connected to the side gear 66 through the bevel gear group 67, a No. 3 air port 689 is provided at the bottom of the cylinder 681, the No. 3 air port 689 is connected to the No. 3 air nozzle 8 through a connecting pipe, an air inlet 688 is provided above the conical port 684, the air inlet 688 is connected to the blower 69 through a connecting pipe, a No. 2 air port 687 is provided above the cylinder 681, the No. 2 air port 687 is connected to the No. 2 air nozzle 7 through a connecting pipe.

[0047] In the present embodiment, when it is necessary to control the No. 2 air nozzle 7 and the No. 3 air nozzle 8, the transmission motor 61 is first started to drive the single tooth 62 to rotate normally through the connecting shaft, and the upper part of the single tooth 62 is meshed with the bite tooth 63, and the bite tooth 63 is directly connected to the two groups of mounting plates 65 through the main connecting rod 64, and the mounting plate 65 is connected to the No. 2 air nozzle 7 and the No. 3 air nozzle 8, so that the No. 2 air nozzle 7 and the No. 3 air nozzle 8 can be turned over normally. On the other hand, one side of the bite tooth 63 is meshed with the side tooth 66 through the connecting tooth. While driving the No. 3 air nozzle 8 to turn over, the side tooth 66 drives the transmission screw 683 to rotate through the bevel gear group 67. The lower part of the transmission screw 683 is threadedly connected to the block 682, and the two sides of the block 682 are limited and slid with the inner wall of the cylinder 681 through the convex pin block 686, so that the block 682 will move downward, so that the cone block 685 below the block 682 and the cone mouth 684 gradually approach each other. During the approaching process, the air inlet 688 enters the cylinder 68 1 The passage for the gas inside to flow to the No. 3 gas port 689 is gradually reduced, and the air pressure will also decrease accordingly. The No. 3 gas port 689 is directly connected to the No. 3 gas nozzle 8 through the connecting pipe, so that the blowing effect provided to the packaging box body 3 by the No. 3 gas nozzle 8 during the flipping process will gradually decrease. This effect can effectively cooperate to realize the flipping of the packaging box body 3 and prevent the No. 3 gas nozzle 8 from blowing a large amount of air for a long time, causing the packaging box body 3 to be offset and misaligned. When the placement plate 65 is flipped 180 degrees, the No. 2 gas nozzle 7 is now facing the upper part of the left and right side panels of the packaging box body 3. The No. 3 gas nozzle 8 is staggered from the packaging box body 3, and the cone block 685 is also completely fitted with the cone port 684. The air pressure entering the cylinder 681 from the air inlet 688 will be blown out from the No. 2 gas port 687. Here, the No. 2 gas port 687 can be provided with a one-way air valve to realize opening and closing. After the No. 2 gas nozzle 7 blows air, the flanging operation of the packaging box body 3 can be realized.

[0048] refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 The belt-off mechanism 4 includes an electric slider 42 and a stand 43. The stand 43 is fixed on the electric slider 42. The electric slider 42 is slidably arranged on the surface of the slide rail 41. A limit slide groove 44 is provided inside the stand 43. A limit slide groove 45 is provided on the inner wall of the limit slide groove 44 so as to slide up and down. The first air nozzle 5 is fixedly connected to the limit slide groove 45 through a connecting rod. A folding frame 46 is also rotatably connected to one side of the limit slide groove 45 through a convex pin. The top of the folding frame 46 is movably connected to the limit slide groove 45. The bottom of the folding frame 46 is rotatably connected to one side of the electric slider 42 through an axial hole. A transmission tooth 47 is also fixed at the rotation center of the bottom of the folding frame 46. One side of the transmission tooth 47 is meshed with a main meshing tooth 48. The main meshing tooth 48 is meshed with a horizontal meshing rod 49 on the surface of the machine table 11. There is a certain relative distance between the transmission tooth 47 and the horizontal meshing rod 49.

[0049] In this embodiment, in order to ensure that the No. 1 air nozzle 5 can normally provide a downward pressure force to the rear side plate of the packaging box body 3, the closer the No. 1 air nozzle 5 is to the side plate of the packaging box body 3, the better the effect. However, the first conveyor belt 12 will drive the packaging box body 3 to move forward. For this, the electric slider 42 will start to move backward on the surface of the slide rail 41. The movement effect will synchronously drive the No. 1 air nozzle 5 to move until the main gear 48 on one side of the electric slider 42 is engaged with the horizontal gear rod 49 at the specified position. At this time, the rotation of the main gear 48 will drive the transmission gear 47 to rotate. The transmission gear 47 is fixed to the bottom of the folding frame 46, so that the folding frame 46 can be unfolded, and the upper part thereof slides in the limiting slide groove 44 opened inside the vertical frame 43 through the limiting slider 45, and one side of the limiting slider 45 is directly fixed to the No. 1 air nozzle 5 through a connecting rod, so that the No. 1 air nozzle 5 will move upward until the No. 1 air nozzle 5 is located above the packaging box body 3, and then the packaging box body 3 is driven by the first conveyor belt 12 to move to the end, and the above steps are reversed. The No. 1 air nozzle 5 is close to the rear side panel of the packaging box body 3 to provide a blowing downward pressure effect.

[0050] refer to Figure 7 The inner wall height of the limiting slide groove 44 is greater than the height dimension of the packaging box body 3 , and a damping plate is also arranged between the main gear 48 and the electric slider 42 .

[0051] In the present embodiment, the inner wall height of the limiting slide groove 44 is greater than the height of the packaging box body 3 so that the No. 1 air nozzle 5 can move normally to the top of the packaging box body 3 to prevent the packaging box body 3 from colliding with the No. 1 air nozzle 5, and a damping plate is arranged between the main gear 48 and the electric slider 42. This damping plate can provide a certain damping effect to prevent the main gear 48 from rotating under force. Because when the No. 1 air nozzle 5 blows air normally, the air pressure will drive it to move upward, and the damping plate prevents the main gear 48 from rotating, thereby limiting the position of the No. 1 air nozzle 5.

[0052] Working principle: First, the first conveyor belt 12 and the second conveyor belt 13 on one side of the machine 11 move at the same speed, driving the packaging box body 3 on the top to move to one side until the left and right side panels of the packaging box body 3 are separated from the second conveyor belt 13, and move to one end of the first conveyor belt 12 under the support of the first conveyor belt 12, and then the electric slider 42 starts to slide on the surface of the slide rail 41 toward the discharge conveyor belt 14. While sliding, the main gear 48 engages with the horizontal gear rod 49 on the surface of the machine 11, and the main gear 48 rotates through the transmission gear 47 to drive the folding frame 46 to shrink, and the top of the folding frame 46 slides downward in the limiting slide groove 44 in the vertical frame 43 through the limiting slider 45, and synchronously drives the No. 1 gas nozzle 5 to move downward through the connecting shaft until the No. 1 gas nozzle 5 is No. 1 air nozzle 5 is aligned with the rear side panel of the packaging box body 3, and under the air supply of the blower 69, the No. 1 air nozzle 5 blows air to achieve the compression effect of the rear side panel of the packaging box body 3 and the first conveyor belt 12, and then the first conveyor belt 12 and the electric slider 42 continue to move. During this process, the front side panel of the packaging box body 3 is separated from the first conveyor belt 12, and the internal cavity of the packaging box body 3 is exposed. Then the blower 69 blows air to the air inlet 688 through the connecting pipe, and the gas enters the cylinder 681 and directly enters the No. 3 air nozzle 8 through the No. 3 air port 689.
