Description

Technical Field

[0001] This utility model belongs to the field of feeding fixture technology, specifically relating to a feeding fixture for a film applicator. Background Technology

[0002] A screen protector applicator is a tool for applying screen protectors to mobile phones. Its structure is a square frame that resembles the outer contour of a mobile phone, with a cavity in the middle. When applying the screen protector, the mobile phone is placed inside the cavity to position and fix the phone.

[0003] In existing technology, the feeding process for packaging equipment for film applicators usually involves manually placing the film applicators into the material trough. Since the trough diameter must match the outer contour of the film applicator (i.e., the trough diameter of the packaging equipment is the same as the outer contour of the film applicator to allow for neat stacking and easy individual unloading during packaging), manual feeding is inconvenient (due to lack of hand space). This application provides a film applicator feeding clamp. The clamp extends into the cavity of the film applicator, extends out a hook to support the bottom of the film applicator, and one operation can clamp a stack of film applicators. Then, it extends into the material trough of the packaging equipment, releases the hook, and places the stack of film applicators into the trough. The clamp is then withdrawn from the cavity (material trough) of the film applicator, completing the film applicator feeding process. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding clamp for a film applicator. The clamp extends into the cavity of the film applicator, and the hook extends out to support the bottom of the film applicator. One operation can clamp a stack of film applicators. Then, it is inserted into the material trough of the packaging equipment, the hook is released, and the stack of film applicators is placed into the material trough. The clamp is then pulled out from the cavity (material trough) of the film applicator, completing the feeding and material addition process of the film applicator.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A film applicator feeding fixture includes a limiting frame and a telescopic hook assembly;

[0007] The limiting frame is a frame-shaped frame structure with a telescopic claw assembly in the middle.

[0008] Preferably, the limiting frame includes a front guide plate, a rear guide plate, a left guide plate, a right guide plate, and a crossbeam; the front guide plate, rear guide plate, left guide plate, and right guide plate are arranged vertically at intervals, and a horizontally arranged crossbeam is provided between the front guide plate, rear guide plate, left guide plate, and right guide plate, preferably, there are two crossbeams.

[0009] The telescopic claw assembly includes a handle, a push handle, a push rod, a push block, a swing arm, a return spring, and a spring stop. The handle is horizontally positioned, with both ends fixed to the left and right guide plates, and a through hole in its middle. The crossbeam has a bearing hole in its middle, and a linear bearing is installed inside the bearing hole. The through hole and the bearing hole are coaxially aligned. The push rod is vertically positioned, passing through the through hole and the linear bearing, with its top end connected to the horizontally positioned push handle and its bottom end connected to the horizontally positioned push block.

[0010] The bottom of the left guide plate and the right guide plate are respectively provided with horizontally arranged rotating shafts (the bottom left and right sides of the limiting frame are respectively provided with horizontally arranged rotating shafts); the bottom ends of the left guide plate and the right guide plate are respectively provided with hook claw clearance grooves.

[0011] The top of the swing arm is hinged to both sides of the push block, and the middle section of the swing arm is provided with a shaft hole, which is fitted onto the rotating shaft; the bottom of the swing arm is provided with a hook.

[0012] The spring stop is fixed on the push rod;

[0013] The reset spring is sleeved on the outer wall of the push rod and is located between the crossbeam and the spring stop.

[0014] Preferably, to facilitate the insertion of the limiting frame into the cavity of the film applicator, the bottom of the limiting frame is provided with an inwardly inclined guide plate. Specifically, the bottoms of the front guide plate, rear guide plate, left guide plate, and right guide plate are provided with inwardly inclined guide plates.

[0015] Briefly describe its working principle:

[0016] In use, insert the clamp of this application into the neatly stacked film applicators. When material needs to be lifted (clamped), grip the handle with your fingertips, press the push handle with your thumb and forefinger, causing the push rod to press down and push the pressure block down. The pressing block drives the swing arm to rotate, causing the hook to expand outward. The hook can support the bottom of the film applicator, lifting and stabilizing a stack of film applicators, and then feeding this stack of film applicators into the material trough of the packaging equipment. Release the push handle, the push rod returns to its original position, the hook retracts, and the clamp is pulled out from the upper end of the cavity of the film applicator, completing the separation of the film applicator from the clamp.

[0017] The beneficial effects of this utility model are as follows:

[0018] Its structural design is simple and reasonable, stable and reliable; it is convenient to use and easy to operate, with high material feeding efficiency; it can efficiently clamp stacked film applicators (mouth-shaped workpieces) and place them in the material trough of the packaging equipment.
