Description

Technical Field

[0001] The utility model relates to the technical field of nose bridge strip clamping equipment, in particular to a material taking device for grasping double-branch nose bridge strips. Background Art

[0002] In order to facilitate the wearing of masks, masks are usually equipped with nose bridge strips. In the past, during the mask production process, the nose bridge strips were manually cut and then manually assembled onto the masks, with a slow assembly speed. Therefore, at present, automatic nose bridge strip cutting equipment is used in mask production equipment. For example, the nose bridge strip mechanism disclosed in Chinese Patent CN214161638U. However, such equipment unwinds the nose bridge strip through a rotating motor, which is prone to inertia, resulting in excessive unwinding of the nose bridge strip and insufficient stability. Moreover, when dealing with relatively wide types of nose bridge strips such as double-branch nose bridge strips, it cannot be effectively fixed, easily causing the double-branch nose bridge strips to fall off. In view of this, the inventor has made a new invention. Summary of the Utility Model

Detailed implementation mode

[0020] The following combines the attached Figures 1 to 6 to elaborate on the present utility model in detail.

[0021] A material picking device for grasping double - branch nose bridge strips of the present utility model includes a drive belt 1 and a material picker 2. A connecting block 11 is arranged on the drive belt 1. The material picker 2 is provided with a positioning part 21 connected to the connecting block 11 and a movable part 22 movably connected to the positioning part 21. The positioning part 21 and the movable part 22 cooperate with each other to form a clamp shape. A limiting plate 2101 is arranged at the top of the positioning part 21. The limiting plate 2101 is in an inverted L shape. A movable rod 221 passing through the positioning part 21 is arranged above the movable part 22. A first elastic part 2102 is arranged between the limiting plate 2101 and the top of the movable rod 221. A support rod 222 is arranged below the movable part 22. A ball 223 is arranged at the bottom of the support rod 222. A support disk 3 is arranged below the drive belt 1. The support disk 3 is provided with a chassis 31. A heightening block 32 is arranged on the chassis 31. The ball 223 can move on the chassis 31 and the heightening block 32 to make the movable part 22 lift and move. Specifically, the structure of the support disk 3 is as Figure 5As shown, the support block 32 is arranged above a part of the chassis 31, and the transmission belt 1 drives the material picker 2 to move. During this process, the ball 223 rolls on the chassis 31, the movable part 22 sinks, and there is a large gap between the movable part 22 and the positioning part 21. At this time, the material picker 2 is in an open state. After the ball 223 moves to the top of the support block 32, the height of the support block 32 supports the movable part 22, so that the movable part 22 closes to the positioning part 21. The movable part 22 and the positioning part 21 cooperate with each other to clamp the double nose bridge strips. At this time, the first elastic part 2 102 is squeezed and begins to accumulate elastic force, and then the material picker 2 continues to move. When the ball 223 moves from the support block 32 to the chassis 31, the first elastic member 2102 releases the elastic force to open the movable rod 221 and the limit plate 2101, and applies a downward force to the movable rod 221, so that the movable member 22 moves downward, thereby opening the material picker 2, thereby completing the operation of grabbing and placing the double-branch nose bridge strip. The material picking device of the utility model has high precision, greatly reduces the impact of equipment jitter and moving inertia, and has a fast material picking speed and high stability. More specifically, the positioning member 21 is provided with a feed trough 2103, and the movable member 22 is provided with a feed trough 224 that cooperates with the feed trough 2103. Figure 2 As shown, both sides of the upper material trough 2103 and the lower material trough 224 are grooves for positioning the two sides of the double-branch nose bridge strip, the middle parts of the upper material trough 2103 and the lower material trough 224 are convex, which are used to clamp and fix the middle part of the double-branch nose bridge strip, and extension blocks 2104 are arranged on both sides of the positioning member 21, and an airway 2105 is arranged in the extension block 2104, and an airway 2105 is arranged at one end of the airway 2105. A trachea 2106 is arranged, and a retractable and movable push plate 23 is arranged at the other end of the airway 2105. After the material picker 2 grabs the cut double-branch nose bridge strip and moves it to a specified position, the movable part 22 sinks, the upper material trough 2103 and the lower material trough 224 move away from each other, and then the trachea 2106 provides air pressure to push the push plate 23 out, and the push plate 23 pushes the double-branch nose bridge strip placed on the lower material trough 224 out to complete the material discharge operation, and finally the trachea 2106 provides negative pressure to reset the push plate 23.

[0022] The transmission belt 1 is provided with four rollers 12, which support the transmission belt 1 so that the transmission belt 1 forms a rounded rectangle. The rounded rectangular transmission belt 1 allows the picker 2 to move horizontally to grab and place the double nose bridge strips. After the picker 2 grabs the double nose bridge strips, it can move to another direction to place the double nose bridge strips.

[0023] Slopes 33 are provided at both ends of the support block 32. The angle between the slope 33 and the chassis 31 is less than 20 degrees, the process of the ball 223 from the chassis 31 to the support block 32 is smooth, and the lifting process of the movable part 22 is gentle and stable.

[0024] A guiding groove 13 is provided on the connecting block 11, and a guiding strip 2107 matching with the guiding groove 13 is provided on the positioning member 21. This structure enables the positioning member 21 to slide up and down, and the height of the positioning member 21 can be finely adjusted, facilitating the gripper 2 to grasp double-branch nose bridge strips with different thicknesses.

[0025] A more specific adjusting structure of the positioning member 21 includes 2108. A limiting block is provided above the connecting block 11. 2108 is threadedly connected to the limiting block, and one end of the 2108 is movably connected to the positioning member 21. The position of the positioning member 21 can be finely adjusted by screwing the bolt.

[0026] A receiving groove 225 for accommodating the ball 223 is provided in the support rod 222, and a second elastic member 226 is provided in the receiving groove 225. The ball 223 and the support rod 222 are supported by the second elastic member 226, enabling the ball 223 to have a buffering capacity, reducing the wear speed of the ball 223, and extending the service life.

[0027] Air holes 2109 are provided on the limiting plate 2101, and the air pipe 2106 is fixedly connected to the air holes 2109. The push plate 23 is provided with a push rod 24 that can move in the air passage 2105. The air holes 2109 can be externally connected to an air pump. When the air pump blows air into the air pipe 2106 to increase the air pressure, the pressure in the air passage 2105 extrudes the push rod 24, pushing out the push plate 23; when the air pump sucks air from the air pipe 2106 to reduce the air pressure, the negative pressure in the air passage 2105 sucks the push rod 24 in, resetting the push plate 23.

[0028] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
