[0036] 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.

[0037] refer to Figure 1-9 , including a workbench group 2 slidably arranged above a base 1, a conveyor belt 3 is arranged on the surface of the base 1 near the workbench group 2, the workbench group 2 includes a placement plate 21, a combination table 22 and a loading table 23, the loading table 23 is fixedly arranged on one side of the placement plate 21, one side of the bottom surface of the combination table 22 is movably arranged above the placement plate 21 through two groups of main unloading mechanisms 6, and the other side of the bottom surface of the combination table 22 is rotatably arranged above the placement plate 21 through an axle pin, and a buckle cover 4 is arranged on the top of the base 1 to move up and down through a grabbing and packaging mechanism 5, and the buckle cover 4 is located directly above the combination table 22, and an auxiliary unloading mechanism 9 is arranged on the surface of the combination table 22;

[0038] The active motor 61 drives the lead screw 64 to move horizontally on the surface of the placement plate 21 through the separation mechanism 7. Two sets of support plates 66 are movably provided on one side of the lead screw 64 through a slide plate. The top of the support plate 66 is movably connected to the bottom of the combined table 22 through a side plate.

[0039] The meshing slide 81 is slidably arranged on the side of the base 1. The meshing slide 81 is elastically connected to the base 1 through a spring rod 87. A meshing tooth set 82 is meshed on the top of the meshing slide 81. The meshing tooth set 82 is limited and movable on the surface of the placement plate 21 through a transmission rod 83. The meshing slide 81 is transmission-connected to the active motor 61 through the meshing tooth set 82 and the spline cylinder 77. One end of the transmission rod 83 is fixed to the spline cylinder 77.

[0040] The grabbing and packaging mechanism 5 includes an actuator electric cylinder 51 and an I-shaped frame 53. The actuator electric cylinder 51 is fixed to the I-shaped frame 53 by a sliding column 52. The sliding column 52 is sealed and telescopic with the top of the buckle cover 4. The I-shaped frame 53 is externally connected to a first suction pipe 54. A suction cup is arranged on the bottom surface of the I-shaped frame 53. A second suction pipe 55 is arranged on the surface of the buckle cover 4. The first suction pipe 54 and the second suction pipe 55 are respectively externally connected to vacuum components.

[0041] In this embodiment, the workbench group 2 is composed of a placement plate 21, a combined table top 22 and a loading table 23. Only the placement plate 21 and the loading table 23 slide with the base 1 through a sliding block. During the sliding process, the loading table 23 can send the top cover belt to the bottom of the buckle cover 4, and the buckle cover 4 is driven down by the grabbing and packaging mechanism 5 to fit with the surface of the loading table 23, so as to achieve the grabbing of the cover. At the same time, the placement plate 21 moves to the other side, and the combined table top 22 on its top can realize the placement of the packaging box. After moving back again, the packaging operation can be realized, and the loading table 23 can load the cover at this time. The overall continuous effect is strong, time is effectively used, and the packaging production efficiency is improved.

[0042] Specifically, after the execution electric cylinder 51 is started, the sliding column 52 drives the I-shaped frame 53 to descend, while the buckle cover 4 is not restricted and will also descend synchronously under the action of its own gravity until the bottom of the buckle cover 4 is in contact with the top of the combined table 22. At this time, the buckle cover 4 realizes air suction through the second suction pipe 55, and a closed cavity is formed between the buckle cover 4 and the combined table 22, and the internal pressure decreases. In this process, the bottom of the I-shaped frame 53 is in contact with the top surface of the cover through the suction cup, and the first suction pipe 54 realizes suction to generate negative pressure, effectively grabbing the cover. The continuous driving of the execution electric cylinder 51 cannot continue to drive the buckle cover 4 to descend at this time, so that the sealing slide between the sliding column 52 and the buckle cover 4 The first suction pipe 54 is then filled with air, and the buckle cover 4 is separated from the I-shaped frame 53. Then, the air pressure in the buckle cover 4 rises. The air pressure in the cover and the packaging box is in a negative pressure state due to the previous suction effect, so that the cover and the packaging box can be automatically closed and packaged. Compared with manual operation, it can effectively improve the packaging efficiency and reduce the packaging time. It is worth noting that the pressure drop threshold of the buckle cover 4 cannot be greater than the adsorption pressure threshold of the suction cup at the bottom of the I-shaped frame 53 and the surface of the buckle cover 4. This effect is achieved by adjusting the vacuum component externally connected to the first suction pipe 54 and the second suction pipe 55, which will not be elaborated here.

[0043] In addition, after the packaging is completed, the start of the active motor 61 can drive the lead screw 64 to move, thereby pulling the support plate 66. At this time, the combined table 22 is pulled by the support plate 66 to move downward on one side, thereby facilitating the unloading of products. At the same time, the auxiliary unloading mechanism 9 on the surface of the combined table 22 is driven to realize the specific unloading operation.

[0044] Although the meshing slide 81 is slidably set on the side of the base 1, under normal circumstances, it is stabilized by the elastic force of the spring rod 87. In this way, the active motor 61 can drive the meshing tooth group 82 to rotate normally through the connection of the spline cylinder 77 and the transmission rod 83 after being driven. In this way, when the meshing tooth group 82 rotates on the top of the meshing slide 81, it can drive the workbench group 2 as a whole to move horizontally, thereby achieving a displacement effect.

[0045] refer to Figure 4 , 5 , 8 and Fig. 9 The separation mechanism 7 includes an electric push rod 71, a first blocking plate 75 and a second blocking plate 76. The output end of the electric push rod 71 is fixedly connected to the connecting frame 72, and the connecting frame 72 is movably connected to the spline rod 74 through the bearing wheel 73. The first blocking plate 75 is fixed to one end of the spline rod 74, and the first blocking plate 75 and the second blocking plate 76 are slidably fitted. The spline rod 74 and one side of the spline cylinder 77 are telescopically movable. The surface of the spline cylinder 77 is connected to the output shaft of the active motor 61 through a bevel gear set. The rotation of the spline cylinder 77 drives the spline rod 74 to rotate.

[0046] After the cam 72 is in the state of rotation and the spring 76 is in the state of rotation, the spring 76 and the spring 77 are in the state of rotation, and the spring 76 and the spring 77 are in the state of rotation.

[0047] refer to Figure 4 and Figure 5 One side of the second blocking plate 76 is fixedly connected to the transmission gear set 62 through a coupling shaft. The transmission gear set 62 is composed of two sets of bevel gears and a single set of transmission teeth, and one side of the transmission teeth is meshed with a transmission gear 63. The second blocking plate 76 drives the transmission gear 63 to rotate through the transmission gear set 62. The transmission gear 63 is threadedly connected to the surface of the lead screw 64. The transmission gear 63 and the transmission gear set 62 are limited to rotate on the surface of the placement plate 21 through the side plate. The slide 65 is fixedly set on the surface of the placement plate 21. The slide plate on one side of the lead screw 64 is limited by sliding with the slide 65.

[0048] In this embodiment, the driving motor 61 drives the transmission gear 63 to rotate through the transmission gear set 62, and the effect is first achieved by the docking of the second blocking plate 76 of the first blocking plate 75, and the transmission gear set 62 is composed of two sets of bevel gears and a single set of transmission teeth, the two sets of bevel gears are meshed with each other and the sides are respectively connected to the single set of transmission teeth and the second blocking plate 76, and the single set of transmission teeth is directly meshed with the outside of the transmission gear 63, so that the transmission gear 63 rotates to a specified position above the placement plate 21, and under the influence of the threaded connection effect, the lead screw 64 will be driven by the transmission gear 63 to move to one side, thereby driving the combined table 22 to tilt or flush above the placement plate 21 through the support plate 66;

[0049] Reference may be made to the transmission effect of the screw-nut pair in the prior art, where the movement is transformed into the screw body.

[0050] refer to Figure 2 and Figure 3 , the base 1 is provided with a moving mechanism 8 on both sides, the moving mechanism 8 includes a meshing slide 81 and a meshing tooth set 82, the base 1 is fixedly provided with a first blocking protrusion 84 at the sliding extreme point position close to the meshing slide 81, and the meshing slide 81 and the first blocking protrusion 84 are in conflict with each other. The moving mechanism 8 also includes a blocking rod 86 and a second blocking protrusion 85, the blocking rod 86 is fixed at the bottom side position of the loading platform 23, the second blocking protrusion 85 is fixed at the side of the base 1 close to the moving track of the blocking rod 86, and the first blocking protrusion 84 and the second blocking protrusion 85 are both arranged at the same lateral position of the blocking rod 86 and the meshing slide 81.

[0051] In this embodiment, the moving mechanism 8 can play a stabilizing role in this device, combined with Figure 1 , two 3. It is necessary to interpret the transmission separation of the active motor 61 in cooperation with the separation mechanism 7 in four situations:

[0052] Case 1: That is Figure 3 In the situation in the figure, after the workbench group 2 as a whole moves to the specified position, the combined table surface 22 is aligned with the bottom of the buckle cover 4. At this time, the active motor 61 will continue to drive the meshing tooth group 82 to rotate, and the bottom of the loading platform 23 will contact the second blocking protrusion 85 on the side of the base 1 through the blocking rod 86, and the workbench group 2 as a whole can no longer continue to move, so that the rotation of the meshing tooth group 82 will drive the meshing slide 81 to move to the right, and at the same time squeeze the spring rod 87 under the meshing slide 81 to generate elastic potential energy. Therefore, at this time, the position of the workbench group 2 as a whole above the base 1 will be more stable under the action of elastic resistance, preventing left and right shaking from affecting the docking operation between the cover and the packaging box;

[0053] Case 2: The separation mechanism 7 achieves the connection between the active motor 61 and the transmission gear set 62 at this time, and the active motor 61 is then reversed. During the reversal process, the transmission gear set 62 and the meshing gear set 82 are synchronously driven to rotate. On the one hand, the rotation of the transmission gear set 62 realizes the tilting of the combined table 22, which is convenient for unloading. On the other hand, since the meshing slide 81 has elastic potential energy at this time, the rotation of the meshing gear set 82 realizes the movement of the meshing slide 81 to the left, releasing the elastic potential energy, but the overall position of the workbench group 2 does not move. At this time, the unloading operation can be realized through the auxiliary unloading mechanism 9 on the surface of the workbench group 2.

[0054] Case 3: After the material is unloaded, the separation mechanism 7 separates the active motor 61 and the transmission gear set 62, and the meshing slide 81 also completely releases the elastic potential energy of the spring rod 87. At this time, the meshing slide 81 will conflict with the first stop 84, and the meshing gear set 82 will rotate above the meshing slide 81. Under the meshing effect, the meshing gear set 82 can drive the workbench set 2 to move to the right above the base 1 as a whole until it moves to the specified position.

[0055] Case 4: the separation mechanism 7 realizes the docking of the active motor 61 and the transmission gear set 62 again, and the active motor 61 reverses again, and the meshing slide 81 does not move under the elastic force of the spring rod 87, so the workbench group 2 moves to the left as a whole, and the combination table 22 is also reset until it is flush with the placement plate 21. At this time, the loading table 23 is aligned with the bottom of the buckle cover 4, and the grabbing and packaging mechanism 5 realizes the grabbing operation of the cover;

[0056] Therefore, the purpose of automated packaging production can be achieved by reciprocating the above steps.

[0057] refer to Figure 6 and Figure 7 The auxiliary unloading mechanism 9 includes a pull rod 94 and an electromagnetic actuator 97. The pull rod 94 is elastically arranged on the top surface of the combined table 22 through two sets of tension springs 95. A built-in groove 96 is provided at the top of the combined table 22 near the electromagnetic actuator 97. The bottom of the electromagnetic actuator 97 is movably arranged in the built-in groove 96 through an electromagnetic push block. Two sets of winding wheels 93 are arranged on the top of the combined table 22. A pull wire is wound on the surface of the winding wheel 93, and one end of the pull wire is fixed to the pull rod 94. The bottom of the two sets of winding wheels 93 is connected to each other through a transmission belt 92. The bottom of the transmission belt 92 is connected to the output shaft of the driving motor 91 through a bevel gear group. The driving motor 91 is fixed to the bottom of the combined table 22.

[0058] In this embodiment, after starting, the driving motor 91 can drive the two sets of winding wheels 93 to rotate on the top of the combined table 22 through the transmission belt 92. The winding wheels 93 are connected to the pull rod 94 through a pull wire, so that the pull rod 94 will be displaced, pushing the packaged product to be unloaded until the product falls on the surface of the conveyor belt 3, thereby realizing the collection operation. After the driving motor 91 is driven in reverse, the pull rod 94 is pulled to reset under the elastic force of the tension spring 95.

[0059] Working principle: First, the active motor 61 in the main unloading mechanism 6 is started, and the spline cylinder 77 is driven to rotate through the bevel gear group, and the meshing tooth group 82 is driven to rotate through the transmission rod 83. The meshing slide 81 on one side of the base 1 is resisted by the elastic force of the spring rod 87 and the limiting resistance of the first stop convex 84, so that the meshing tooth group 82 rotates and drives the workbench group 2 to move to one side as a whole. Then the loading platform 23 moves to the bottom of the buckle cover 4, and the execution electric cylinder 51 in the grabbing and packaging mechanism 5 drives the work-shaped frame 53 and the buckle cover 4 to descend through the sliding column 52 until the buckle cover 4 is completely buckled with the top of the loading platform 23. At this time, the work-shaped frame 53 continues to descend, and its bottom suction cup is in contact with the top surface of the cover, and the grabbing is achieved under the suction of the first suction pipe 54. The movable cover and the buckle cover 4 rise, and the combination table 22 on the other side also completes the placement of the packaging box. When placing, the electromagnetic actuator 97 can be driven by the electromagnetic push block to rise in the built-in groove 96 to achieve positioning, and then the active motor 61 is reversed, and the combination table 22 returns to the bottom of the buckle cover 4 again, and the grabbing and packaging mechanism 5 drives the buckle cover 4 to descend again and snap-fit ​​and align with the surface of the combination table 22, until the cover under the I-shaped frame 53 is aligned with the packaging box on the top of the combination table 22, and then the second suction pipe 55 sucks the air inside the buckle cover 4 to make its interior present a certain negative pressure state, and then the I-shaped frame 53 continues to descend to achieve the buckle between the cover and the packaging box, and the air is released into the buckle cover 4 through the first suction pipe 54. Under the action of negative pressure, the cover and the packaging box are automatically sealed and docked;

[0060] Then, the electric push rod 71 in the separation mechanism 7 drives the spline rod 74 to move as a whole on one side of the spline cylinder 77 through the connection between the connecting frame 72 and the bearing wheel 73 until the first blocking plate 75 is connected with the second blocking plate 76. At this time, the active motor 61 drives the transmission gear set 62 and the transmission gear teeth 63 to rotate, and the lead screw 64 is forced to move horizontally and pull the combined table 22 through the support plate 66, so that the combined table 22 tilts. At the same time, the meshing slide 81 is forced to squeeze the spring rod 87;

[0061] Finally, the driving motor 91 is started to drive the two sets of reels 93 to rotate through the transmission belt 92, and the pull rod 94 is pulled to drive the product to fall on the surface of the conveyor belt 3 to realize unloading and collection, and reset under the elastic action of the tension spring 95. Repeat the above operation to realize automated production.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
