Description

Technical Field

[0001] This application relates to the field of packaging barrel technology, specifically to a 200L packaging barrel clamping mechanism. Background Technology

[0002] 200L packaging drums can be galvanized steel drums, plastic-lined steel drums, or rotomolded drums. They are commonly used to hold liquid chemicals and may involve operations such as pouring, turning, removing residues, and handling during use.

[0003] The clamping mechanism enables the lifting or forklift handling of packaging drums. In existing technologies, the clamping mechanisms primarily function through gravity clamping and mechanical clamping. Gravity clamping works by the lower jaw support and upper jaw hook engaging the top flange of the packaging drum under the action of a lever. The clamping force obtained by the lever is provided by the weight of the packaging drum and its contents; the heavier the drum, the tighter it is clamped. Mechanical clamping can be achieved using a packaging drum tipping cart. The clamping part of the cart is located at the waist of the drum, and the device wraps circumferentially around the outer wall of the drum. Its clamping force is provided by hydraulic pressure or a cylinder and is independent of gravity.

[0004] However, gravity clamps can only move up and down, making them suitable only as auxiliary tools for handling operations. They are not suitable for applications involving barrel tipping and are difficult to apply in assembly line operations. Furthermore, the design of barrel tipping carts requires uniform clamping force distribution and a large effective area; otherwise, uneven force distribution can lead to barrel deformation or even bursting. This increases the difficulty of controlling the friction between the clamping force and the barrel, easily causing damage to the packaging barrels. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a 200L packaging drum clamping mechanism.

[0006] This application adopts the following technical solution: a 200L packaging barrel clamping mechanism, located on the outside of the barrel body, including an upper jaw hook, a lower jaw support and a cylinder, the middle part of the upper jaw hook is movably located on the top outside of the lower jaw support, one end of the upper jaw hook is provided with a hook groove, the cylinder is movably located on the lower outside of the lower jaw support, and the push rod of the cylinder is movably connected to the other end of the upper jaw hook;

[0007] The cylinder is used to push the upper jaw hook to rotate around the lower jaw support. When the cylinder push rod is in the retracted state, the hook groove is away from the flange of the barrel. When the cylinder push rod is in the extended state, the hook groove is engaged on the outside of the flange.

[0008] Optionally, the chin rest is detachably connected to the barrel body, and the top of the chin rest fits into the bottom of the flange.

[0009] Optionally, the top outer side of the lower jaw support is provided with a rotating shaft, the lower outer side of the lower jaw support is provided with a first fulcrum for mounting of the air cylinder, the upper jaw hook is provided with a second fulcrum for mounting of the air cylinder, the middle part of the upper jaw hook is sleeved on the rotating shaft, and the two ends of the air cylinder are connected with the lower jaw support and the upper jaw hook, so that the upper jaw hook can rotate around the rotating shaft when the air cylinder is extended or retracted.

[0010] Optionally, the upper jaw hook can rotate around the rotating shaft, and the rotation of the upper jaw hook around the rotating shaft is realized by extension or retraction of the air cylinder.

[0011] Optionally, the hook groove is adaptively clamped on the outer side of the flange of the barrel body, one end of the upper jaw hook provided with the hook groove is provided with a pressing head, and when the flange is clamped in the hook groove, the pressing head is pressed against the top of the barrel body.

[0012] Compared with the prior art, when the lower jaw support is close to the bottom of the flange of the barrel body, the air cylinder is extended to the end position, at this time, the upper jaw hook is downwardly clamped, so that the hook groove and the flange are in a tightly clamped state, and in the case that the air cylinder remains in the extended state, the upper jaw hook and the flange can remain in the clamped state, so that the clamping force is in an independent state and is not affected by gravity, that is, even if the barrel body has landed, the hook groove will not be loosened, and the clamping effect on the barrel body is significantly improved.

[0017] In the following, the present application is further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0018] As Figs. 1-3As shown, a 200L packaging barrel clamping mechanism is arranged outside the barrel body 1, which comprises an upper jaw hook 2, a lower jaw support 3 and a gas cylinder 4. The middle part of the upper jaw hook 2 is movably arranged outside the top of the lower jaw support 3. One end of the upper jaw hook 2 is provided with a hook groove 21. The gas cylinder 4 is movably arranged outside the lower part of the lower jaw support 3. The push rod of the gas cylinder 4 is movably connected to the other end of the upper jaw hook 2. The outer edge of the top of the barrel body 1 is provided with a flange 10. The gas cylinder 4 is used to push the upper jaw hook 2 to rotate around the lower jaw support 3. When the push rod of the gas cylinder 4 is in the retracted state, the hook groove 21 is away from the flange 10. When the push rod of the gas cylinder 4 is in the extended state, the hook groove 21 is clamped outside the flange 10.

[0019] In use, the lower jaw support 3 is first attached to and fixed to the outer wall of the barrel body 1, and then the push rod of the gas cylinder 4 is extended. In this way, under the pushing of the gas cylinder 4, the upper jaw hook 2 can rotate around the lower jaw support 3. When the push rod of the gas cylinder 4 is fully extended, the hook groove 21 of the upper jaw hook 2 can be reliably clamped outside the flange 10. In this way, as long as the push rod of the gas cylinder 4 remains extended, the upper jaw hook 2 and the flange 10 can remain clamped. This allows the clamping mechanism to reliably clamp the barrel body 1, and enables the barrel body 1 to reliably perform necessary actions such as rotation and automatic overturning during automated and intelligent conveying, residual removal and the like. The clamping force is independent of gravity, effectively improving the clamping effect and preventing damage to the barrel body 1.

[0020] The top of the lower jaw support 3 is attached to the bottom of the flange 10. In this way, under the action of the extension force of the gas cylinder, the lower jaw support 3 and the upper jaw hook 2 are in a biting state, which can ensure that the barrel body 1 and the clamping mechanism do not fall off during movement or overturning of the barrel body 1.

[0021] The top outside of the lower jaw support 3 is provided with a rotating shaft 31. The lower outside of the lower jaw support 3 is provided with a first fulcrum 32 for mounting the gas cylinder 4. The upper jaw hook 2 is provided with a second fulcrum 22 for mounting the gas cylinder 4. The middle part of the upper jaw hook 2 is sleeved on the rotating shaft 31. The two ends of the gas cylinder 4 are respectively connected to the first fulcrum 32 of the lower jaw support 3 and the second fulcrum 22 of the upper jaw hook 2. When the gas cylinder 4 is extended and retracted, the upper jaw hook 2 can rotate around the rotating shaft 31.

[0022] The upper jaw hook 2 can rotate around the rotating shaft 31 by the extension and retraction of the gas cylinder 4. In this way, the lower jaw support 3, the upper jaw hook 2 and the gas cylinder 4 can be linked, thereby ensuring that the upper jaw hook 2 can reliably rotate around the lower jaw support 3 under the pushing of the gas cylinder 4, and further forming a clamping action on the barrel body 1 through the interaction of the hook groove 21 and the flange 10.

[0023] According to the size of the flange 10, the size of the hook groove 21 can be reasonably set, so that the hook groove 21 can be adaptively clamped on the outside of the flange 10. One end of the upper jaw hook 2 provided with the hook groove 21 is provided with a pressing head 23. When the flange 10 is clamped into the hook groove 21, the pressing head 23 is pressed against the top of the barrel body 1. Under the pressing action of the pressing head 23, the upper jaw hook 2 and the barrel body 1 can be more reliably clamped, significantly improving the clamping effect of the clamping mechanism on the barrel body 1.

[0024] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
