Therefore, when the surface of the plastic product is uneven, a gap may be generated between the suction cup and the surface of the plastic product, resulting in insufficient suction between the suction cup and the plastic product, causing the plastic product to fall off easily. Therefore, a self-grabbing suction cup for a fully automatic high-speed blister machine is proposed to solve the above problem. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a self-grabbing suction cup of a fully automatic high-speed blister molding machine, comprising an inner plate 1, the inner plate 1 is in the shape of a circular ring, the outer wall of the inner plate 1 is slidably connected to the outer plate 2, and the shape setting of the inner plate 1 ensures that the gas between the bottom end of the inner plate 1 and the inner side of the outer plate 2 can be discharged through the hole in the middle of the inner plate 1, the shape of the outer plate 2 is annular, and the material of the outer plate 2 is set to rubber, and an annular protrusion is provided at the outer bottom end of the inner plate 1, and the setting of the annular protrusion ensures that the outer plate 2 can be moved to the lowest position relative to the inner plate 1 to be fixed.
[0032] Reference Figure 2 - Figure 4The outer disk 2 is provided with a welt assembly 3 inside the outer disk 2, and the welt assembly 3 includes a mounting chamber 31, which is opened on the lower surface of the outer disk 2, and the inner wall of the mounting chamber 31 is fixedly connected with a shaping plate 32. The shape of the shaping plate 32 is set to be annular, and the material of the shaping plate 32 is set to metal. Through the material setting of the shaping plate 32, it is ensured that the shape of the outer disk 2 can be controlled to a certain extent by the internal shaping plate 32, thereby ensuring that the outer disk 2 is not easily deformed with the increase of use time. The inner wall of the mounting chamber 31 is slidably connected with a movable plate 33, and the number of movable plates 33 is set to be multiple, and the multiple movable plates 33 are arranged in a ring array with the center of the outer disk 2 as the center. The shape formed by the multiple movable plates 33 is consistent with the shape of the shaping plate 32. Through the setting of multiple movable plates 33, it is ensured that the positions of the movable plates 33 in different positions in the up and down directions can be different, thereby facilitating contact with the surface of plastic products with uneven surfaces.
[0033] Reference Figure 2 - Figure 4 The upper end of the movable plate 33 is elastically connected to the lower end of the shaping plate 32 by a spring 1 34, one end of the spring 1 34 is fixedly connected to the upper end of the movable plate 33, and the other end of the spring 1 34 is fixedly connected to the lower end of the shaping plate 32. The lower end of the movable plate 33 is fixedly connected with a liquid bag 35, and the material of the liquid bag 35 is set to soft rubber, and the liquid bag 35 is only fixed to the middle part of the lower end of the movable plate 33. The material of the liquid bag 35 and the setting of the fixed position of the liquid bag 35 ensure that the liquid bag 35 can be deformed as needed. The top of the inner disk 1 is fixedly connected to a foldable hose 4, which can change the vertical position. The setting of the foldable hose 4 ensures that the gas storage capacity inside the foldable hose 4 and the inner disk 1 can be increased, thereby ensuring that when a heavier plastic product is sucked by the suction cup, the deformation of the foldable hose 4 can increase the air pressure inside the foldable hose 4 and the inner disk 1, thereby enhancing the suction force, so that the plastic product is not easy to fall off.
[0034] Reference Figure 1 - Figure 3 The inner wall of the foldable hose 4 is penetrated and fixedly connected with an air suction pipe 5, which is used to connect to the air pump. Through the setting of the air suction pipe 5, it is ensured that the gas below the inner disk 1 and inside the outer disk 2 can be sucked out. The outer wall of the inner disk 1 is fixedly connected with a positioning ring 6. The lower end of the positioning ring 6 and the upper end of the outer disk 2 are elastically connected by a spring 2 7. One end of the spring 2 7 is fixedly connected to the lower end of the positioning ring 6, and the other end of the spring 2 7 is fixedly connected to the upper end of the outer disk 2. The elastic force of the spring 2 7 is much greater than the elastic force of the spring 1 34.
[0035] Reference Figure 1 、 Figure 2 and Figure 4The lower end of the inner plate 1 is provided with a leveling component 8, which includes a connecting plate 81. The top of the connecting plate 81 is fixedly connected to the lower surface of the inner plate 1, and the lower end of the connecting plate 81 is fixedly connected to a buffer ball 82. The shape of the buffer ball 82 is hemispherical, and the material of the buffer ball 82 is set to soft rubber. The shape setting of the buffer ball 82 ensures that when the buffer ball 82 just contacts the plastic product, only the tip of the spherical surface contacts it, and it can increase the contact area with the plastic product as the inner plate 1 moves downward, thereby avoiding damage to the plastic product due to sudden contact with the suction cup and a large contact area. The interior of the buffer ball 82 is connected to the interior of the connecting plate 81.
[0036] Working principle: When in use, the staff pushes the inner plate 1 through external force. Since the outer plate 2 is at the lower end of the inner plate 1 and the elastic force of the spring 2 7 is greater than the elastic force of the spring 1 34, when the outer plate 2 is pushed, the liquid capsule 35 below the outer plate 2 first contacts the surface of the plastic product.
[0037] When the liquid capsule 35 contacts the surface of the plastic product, the surface of the liquid capsule 35 is subjected to force, so that the liquid capsule 35 can be deformed accordingly according to the shape of the surface of the plastic product, and the fluidity of the liquid makes the interior of the liquid capsule 35 stable. At the same time, when the liquid capsule 35 is subjected to force and deformed to a certain extent, the liquid capsule 35 is further subjected to force, which pushes the movable plate 33, so that the movable plate 33 moves toward the direction close to the shaping plate 32 after being subjected to force, until the movable plate 33 moves to a point where it cannot move.
[0038] Since there are multiple movable plates 33, the heights of different movable plates 33 can be at different positions, so it is not easy for gaps to be easily generated due to the plastic product being at a lower position and being subjected to less force, so that the fit between the plastic product and the liquid capsule 35 can be ensured to be better.
[0039] When the movable plate 33 cannot be displaced relative to the shaping plate 32, the staff continues to push the inner plate 1. At this time, the inner plate 1 moves downward relative to the outer plate 2. As the inner plate 1 moves, the outer wall of the buffer ball 82 can contact the surface of the plastic product.
[0040] Since the buffer ball 82 is spherical in shape, when the buffer ball 82 first contacts the surface of the plastic product, the contact surface is only one point where the plastic product and the buffer ball 82 contact each other. As the inner disk 1 moves, the contact surface between the buffer ball 82 and the plastic product gradually increases.
[0041] At the same time, in the process of moving the inner plate 1, the suction pump connected to the suction pipe 5 is started, so that the suction pipe 5 sucks the gas at the bottom of the inner plate 1 and the middle of the outer plate 2 outward. Since the contact area between the buffer ball 82 and the plastic product is gradually increased, it is not easy for some gas to not be sucked away. Therefore, it can ensure that the suction force between the suction cup and the plastic product is sufficient and it is not easy to fall off.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
