Description

Technical Field

[0001] This utility model relates to the field of powder injection production technology, and in particular to a capping mechanism for powder injection packaging equipment. Background Technology

[0002] When packaging powder injections, the powder is first injected into the packaging bottle, then sealed with a plastic cap, and then covered with an aluminum cap to ensure its airtightness.

[0003] The existing capping mechanism requires an additional power mechanism in addition to a hydraulic cylinder and rotary motor to push the pressure plate inward to tighten the bottom of the aluminum cap. Therefore, the capping mechanism has too many power components, and the coordination between them is prone to errors, which affects the smooth packaging of powder injections. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a capping mechanism for powder injection packaging equipment, which effectively solves the problem of misalignment that can easily occur when multiple power sources are involved.

[0005] The technical solution to the technical problem is: a capping mechanism for powder injection packaging equipment, including a fixed plate, a hydraulic cylinder fixed on the fixed plate, connecting plates spaced apart at the bottom of the fixed plate, a motor on the connecting plate, the telescopic rod of the hydraulic cylinder fixedly connected to the motor, the output shaft of the motor connected to a sleeve, a spinning mechanism telescopically arranged inside the sleeve, the spinning mechanism including a connecting block telescopically arranged inside the sleeve, a rotating plate rotatably arranged at the bottom of the connecting block, multiple connecting rods rotatably connected to the outside of the sleeve, multiple first pressure plates rotatably arranged on the outside of the connecting block, a second pressure plate hinged to the end of the first pressure plate, and one end of the second pressure plate movably connected to the connecting rod.

[0006] Preferably, the connecting plate is provided with a plurality of guide rods passing through the fixing plate.

[0007] Preferably, the sleeve has an internal cavity with a regular hexagonal cross-section, the top of the connecting block has a hexagonal prism that mates with the cavity, and a spring is provided between the top of the connecting block and the cavity.

[0008] Preferably, the sleeve has a first connecting lug on its outer side, and the connecting rod rotates within the first connecting lug.

[0009] Preferably, the first pressure plate and the connecting block, and the first pressure plate and the second pressure plate are rotatably connected by hinges.

[0010] Preferably, the middle part of the second pressure plate is hinged to the first pressure plate, and the end of the second pressure plate is provided with a second connecting lug that is rotatably connected to the connecting rod.

[0011] This utility model has a simple and ingenious structure and is easy to use. By connecting the connecting rod with the first pressure plate and the second pressure plate, the lower end of the aluminum cap can be spun, reducing the need for a power source and saving energy while achieving smooth and unified operation, thus ensuring the smooth packaging of powder injections.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It is known that a capping mechanism for a powder injection packaging device includes a fixed plate 1, a hydraulic cylinder 2 fixed on the fixed plate 1, connecting plates 3 spaced apart at the bottom of the fixed plate 1, a motor 4 mounted on the connecting plates 3, a telescopic rod of the hydraulic cylinder 2 fixedly connected to the motor 4, an output shaft of the motor 4 connected to a sleeve 5, a spinning mechanism telescopically mounted inside the sleeve 5, the spinning mechanism including a connecting block 6 telescopically mounted inside the sleeve 5, a rotating plate 7 rotatably mounted at the bottom of the connecting block 6, multiple connecting rods 8 rotatably connected to the outside of the sleeve 5, multiple first pressure plates 9 rotatably mounted on the outside of the connecting block 6, a second pressure plate 10 hinged to the end of the first pressure plate 9, and one end of the second pressure plate 10 movably connected to the connecting rod 8.

[0018] In practical use, this utility model

[0019] After the powder injection is filled and the plastic cap is fixed, the aluminum cap is placed on top and moved below the device. The hydraulic cylinder 2 moves downward, and the rotating plate 7 contacts the aluminum cap, pressing it firmly onto the packaging bottle. The motor 4 drives the device to rotate, and the first pressure plate 9 and the second pressure plate 10 rotate to press the aluminum cap. Due to the downward movement of the hydraulic cylinder 2, the sleeve 5 moves downward, causing the connecting rod 8 to push the second pressure plate 10 and the first pressure plate 9 to rotate. The first pressure plate 9 is in a vertical state, and the second pressure plate 10 is in a horizontal state after rotation, pressing the side and bottom edges of the aluminum cap onto the outside of the plastic cap, thus completing the packaging of the powder injection.

[0020] In this mechanism, hydraulic cylinder 2 controls lifting and motor 4 controls rotation. Only two power sources are used, eliminating the need for additional power sources and reducing the configuration of power sources, making the operation of the equipment more coordinated and unified.

[0021] The connecting plate 3 is provided with multiple guide rods 11 that pass through the fixed plate 1, so that the connecting plate 3 and the fixed plate 1 remain stable.

[0022] The sleeve 5 has a cavity 12 inside, and the cavity 12 has a regular hexagonal cross section. The top of the connecting block 6 has a hexagonal prism 13 that mates with the cavity 12. A spring 14 is provided between the top of the connecting block 6 and the cavity 12. When the rotating plate 7 contacts the plastic cover, the hydraulic cylinder 2 continues to push the sleeve 5 down, the connecting block 6 is inserted into the sleeve 5, the spring 14 is compressed, the sleeve 5 drives the connecting rod 8 down, and pushes the first pressure plate 9 and the second pressure plate 10 to complete the rotation, thereby spinning the aluminum cover.

[0023] The connecting block 6 and the sleeve 5 rotate synchronously, so that the first pressure plate 9, the second pressure plate 10 and the connecting rod 8 rotate synchronously without relative displacement.

[0024] The sleeve 5 is provided with a first connecting lug 15 on the outside. The connecting rod 8 rotates in the first connecting lug 15. The first pressure plate 9 and the connecting block 6, and the first pressure plate 9 and the second pressure plate 10 are rotatably connected by a hinge (the hinge is not shown). The middle part of the second pressure plate 10 is hinged to the first pressure plate 9. The end of the second pressure plate 10 is provided with a second connecting lug 16 that is rotatably connected to the connecting rod 8.

[0025] As the sleeve 5 moves down, the first connecting lug 15 pushes the connecting rod 8 to rotate the second pressure plate 10. The second pressure plate 10 then drives the first pressure plate 9 to rotate. The final configuration is that the first pressure plate 9 is vertical and the second pressure plate 10 is horizontal at the lower end of the first pressure plate 9. Under the drive of the motor 4, the aluminum cover is spun.

[0026] Compared with the prior art, this utility model has the following advantages: it reduces the configuration of the power source, makes the movement of the mechanism smoother, avoids errors in mutual coordination, and ensures the smooth packaging of powder injections.
