Description

TECHNICAL FIELD

[0001] The application relates to the technical field of air automatic feeders, in particular to an adjustable clamp plate assembly and an air automatic feeder. BACKGROUND

[0002] An air automatic feeder, also known as a pneumatic feeder or an air feeder, is a device that uses the principle of air dynamics to transport materials through a pipeline to a designated location. It is commonly used to feed punch presses and has the function of feeding. The structure of the air automatic feeder includes a feeding pipe, a pneumatic motor, a speed reducer, a rotary joint and other parts. Its working principle is that the pneumatic motor drives the speed reducer to rotate, thereby driving the rotary joint to rotate, and the materials are transported from the feeding port to the discharging port. The air automatic feeder has many advantages, such as environmental protection (using air power, not producing any waste gas or noise, and not polluting the environment), wide application range (can be applied to metal, paper, plastic and other materials), high feeding accuracy, simple operation, easy maintenance, etc.

[0003] The fixed clamp plate of the air automatic feeder is an important component of the feeder, which works with the movable clamp plate to clamp and transport materials. During the feeding process, the fixed clamp plate and the movable clamp plate work alternately. When the movable clamp plate clamps the material and moves forward, the fixed clamp plate releases the material; when the movable clamp plate reaches the designated position and releases the material, the fixed clamp plate clamps the material to keep the material stable. In this way, through the alternating work of the fixed clamp plate and the movable clamp plate, the material can be fed into the punch press or other processing equipment in a step-by-step manner.

[0004] During the clamping process of the fixed clamp plate, the material is fixed by extrusion. When the material is soft, the force generated by the extrusion of the fixed clamp plate will extrude marks on the surface of the material, resulting in defects on the surface of the material. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide an adjustable clamp plate assembly and an air automatic feeder to solve the problem of defects on the surface of the material caused by the extrusion of the fixed clamp plate when the material is soft.

[0007] By adopting the technical scheme, the spring can be used to perform the extrusion work in the vertical direction.

[0008] Preferably, the adjustable clamp plate mechanism further comprises a limiting plate welded at the top end of the spring and a connecting rod welded above the limiting plate, the spring is arranged in the through hole of the fixed clamp plate, and a threaded hole is formed in the connecting rod.

[0010] Preferably, the adjustable clamp plate mechanism further comprises a sleeve welded above the fixed clamp plate and a connecting block rotatably connected in the sleeve.

[0011] By adopting the technical scheme, the structure arranged in the sleeve can be stably rotated.

[0012] Preferably, the adjustable clamp plate mechanism further comprises a lead screw vertically welded above the connecting block, and the lead screw is connected in the threaded hole of the connecting rod.

[0013] By adopting the technical scheme, the structure on the rod can be stably rotated during rotation.

[0014] Preferably, the adjustable clamp plate mechanism further comprises a handle fixedly clamped at the top end of the lead screw.

[0015] By adopting the technical scheme, the handle can be conveniently held and rotated, so that the connected structure can be synchronously rotated.
