Description

Technical Field

[0001] This utility model relates to the technical field of rubber band processing, and in particular to a rubber band locking device. Background Technology

[0002] In the final stage of bundling plastic bags, elastic bands need to be attached to the outside of the bundled plastic bags. Due to the need for automated production, the existing technology involves placing a large number of elastic bands in a vibratory feeder, causing the elastic bands to vibrate sequentially along the feeder to the upper end. Then, a robotic arm grabs the elastic bands and transports them to the expansion position in the next step. However, the robotic arm is expensive and prone to failure during long-term reciprocating motion. When using a hook solution to rotate or push the elastic bands out of the vibratory feeder, the elasticity of the elastic bands makes them easy to fall off the hooks. In addition, when setting up this component, it is necessary not only to remove the elastic bands from the vibratory feeder, but also to be able to place the elastic bands onto the expansion device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rubber band locking device in view of the above-mentioned technical deficiencies. The device uses a locking member on the hook. When the hook is inside the vibrating plate, the locking member is attached to the outside of the vibrating plate or the baffle, so that the hook can hook the rubber band out of the vibrating plate. When the hook is removed from the vibrating plate, the lower side of the locking member is attached to the hook to form a limiting space, so that the rubber band can be limited to that position.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a frame and a vibratory plate with a notch at the upper end. A hook for conveying rubber bands is provided at the position corresponding to the notch of the vibratory plate. The hook is driven by a drive mechanism to move back and forth at the notch. A locking member is also rotatably provided on the hook. When the hook is outside the vibratory plate, the lower side of the locking member rests on the hook, and the locking member and the hook form a space for limiting the rubber band.

[0005] To further optimize this technical solution, the hook includes a push arm for pushing the rubber band out of the notch, and a hanging arm for placing the pushed rubber band on it and conveying it outward; the locking member includes a rotating arm whose upper end is rotatably connected to the push arm and a stop arm connected to the lower end of the rotating arm; the stop arm extends toward the hanging arm, and when the hook is outside the vibrating plate, the stop arm rests on the hanging arm to form a closure.

[0006] To further optimize this technical solution, when the hook is located inside the vibrating plate, the locking member is placed on the outside of the vibrating plate on one side of the notch.

[0007] To further optimize this technical solution, an extension plate is provided on the frame extending to one side of the vibratory feed notch; when the hook is located inside the vibratory feed, the locking member is placed on the outside of the extension plate.

[0008] To further optimize this technical solution, the hook is rotatably mounted on the frame, and a cylinder is provided between the hook and the frame; the two ends of the cylinder are rotatably connected to the frame and the hook respectively; used to push the hook to rotate through the notch of the vibratory plate.

[0009] To further optimize this technical solution, the driving mechanism is a push cylinder; the push cylinder is mounted on the frame, and the telescopic end of the push cylinder is provided with a hook for the telescopic hook to pass through the notch of the vibratory plate.

[0010] Compared with the prior art, the present invention has the following advantages: a locking member is set on the hook. When the hook is inside the vibrating plate, the locking member is attached to the outside of the vibrating plate or the baffle, so that the hook can hook the rubber band out of the vibrating plate. When the hook is removed from the vibrating plate, the lower side of the locking member is attached to the hook, so as to form a limiting space, so that the rubber band can be limited to that position.

Example

[0017] Combination Figure 1-3 As shown, the difference from Embodiment 1 is that an extension plate 10 is provided on one side of the notch 2 extending to the vibratory feeder 3 on the frame 1; when the hook 4 is located inside the vibratory feeder, the locking member 5 is placed on the outside of the extension plate 10. Example

[0018] Combination Figure 1-3 As shown, the device includes a frame 1 and a vibratory plate 3 with a notch 2 at the top.

A locking member 5 is also rotatably provided on the hook 4. When the hook 4 is outside the vibratory plate 3, the lower side of the locking member 5 rests on the hook 4, and the locking member 5 and the hook 4 form a space for limiting the rubber band. The hook 4 includes a push arm 6 for pushing the rubber band out of the notch 2, and a hanging arm 7 for placing the pushed rubber band on it and conveying it outward; the locking member 5 includes a rotating arm 8 whose upper end is rotatably connected to the push arm 6 and a stop arm 9 connected to the lower end of the rotating arm 8; the stop arm 9 extends toward the hanging arm 7, and when the hook 4 is outside the vibrating plate 3, the stop arm 9 rests on the hanging arm 7 to form a closure; when the hook 4 is inside the vibrating plate, the locking member 5 rests on the outside of the vibrating plate 3 on one side of the notch 2; the driving mechanism is a push cylinder (not shown in the figure); the push cylinder is mounted on the frame 1, and the extension end of the push cylinder is provided with a hook 4 for extending and retracting the hook 4 through the notch 2 of the vibrating plate 3.
