Description

A Step Feeding Mechanism with Adjustable Stroke

technical field

The utility model relates to a feeding mechanism, in particular to a stepping feeding mechanism with adjustable stroke.

Background technique

The stepping feeding mechanism is widely used in heavy industry fields such as stamping dies, and the technology is relatively mature. However, because of its strong pertinence and the need to design corresponding structures and data according to specific situations, it is not widely used in some equipment in light industries such as animal husbandry and textiles, especially in small enterprises. This is because the feeding stroke on the production line of small enterprises often changes with the requirements of different periods, while the general stroke of the current stepping feeding mechanism is fixed, so its application field is limited.

Contents of the invention

The technical problem to be solved by the utility model is to provide a stepping feeding mechanism with adjustable feeding stroke and wide application fields.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a step-feeding mechanism with adjustable stroke, including a frame, a crank-rocker mechanism, a push rod slider mechanism and a mechanism fixed on the frame. A motor drive device, the motor drive device is connected to the crank rocker mechanism, and a stroke adjustment device is arranged between the push rod slider mechanism and the crank rocker mechanism. the

The crank-rocker mechanism includes a crank, a connecting rod, a rocker and a crankshaft, the lower end of the crank is fixedly connected to the crankshaft, and the crankshaft is connected to the frame. The motor driving device includes a motor and a coupling, the motor is fixedly installed on the side of the frame, the motor is fixedly connected to the crankshaft through the coupling, and the The upper end of the crank is hinged with the rear end of the connecting rod, the front end of the connecting rod is hinged with the upper end of the rocker, and the lower end of the rocker is hinged with the frame.

The push rod slider mechanism includes a push rod and a slider, the lower end of the push rod is hinged on the slider, the frame is provided with guide rails, and the lower surface of the slider is A chute is provided, and the chute is slidably matched with the guide rail.

The stroke adjustment device includes a hinge column, a blocking piece and a connecting screw, the rocker is provided with at least two first hinge holes arranged up and down, and the push rod is provided with a number equal to the first The hinge holes are equal to the second hinge holes arranged up and down, the hinge posts pass through the first hinge hole and the second hinge hole in turn, the catch is blocked on the push rod, the The connecting screw passes through the blocking piece and is screwed to the hinged column.

A first sliding groove is arranged between two adjacent first hinged holes, and a second sliding groove is arranged between two adjacent second hinged holes. the

Compared with the prior art, the utility model has the advantage that a stroke adjustment device is arranged between the push rod slider mechanism and the crank rocker mechanism, by adjusting the stroke adjustment device, the feeding stroke of the stepping feeding mechanism can be adjusted, so that The stepping feeding mechanism can meet the needs of equipment with different feeding strokes, expanding its application field.
