This utility model relates to the field of filter screen processing technology, and more particularly to a water pump filter screen manufacturing equipment. The technical solution includes: a feeding mechanism, with a guiding mechanism movably mounted on the top of the feeding mechanism via a longitudinal telescopic rod, and a cutting mechanism fixedly mounted on the top of the guiding mechanism; the feeding mechanism includes a base frame, with drive rollers rotatably mounted at the front and rear ends of the top of the base frame, and a first guide frame movably mounted on one side of the two drive rollers opposite each other; support plates are movably mounted on both sides inside the base frame; the guiding mechanism includes a top frame, with driven rollers rotatably mounted at the front and rear ends of the bottom of the top frame, and a second guide frame movably mounted on one side of the two driven rollers opposite each other. This utility model solves the problem that the filter screen blank, due to its hard texture, bulges in the middle during conveying, making it difficult to accurately control the cutting depth during laser cutting.

A robot for body painting is provided, which keeps the pressure of paint flowing in a circulation passage of a paint supply device and the pressure of paint present inside a painting head within a proper pressure range by suppressing the posture change of a multi-axis arm as much as possible. The robot for body painting includes a painting head, a storage portion that stores paint, a supply device that can control the pressure of paint flowing in a circulation passage provided between the painting head and the storage portion, and an arm having the painting head and the supply device, the arm being a multi-axis arm that includes a plurality of arm members and movable shaft portions that link the arm members to each other. The robot has a posture control unit that controls the postures of the plurality of arm members to keep the relative position of the painting head and the supply device fixed or suppress the change in the relative position within a prescribed allowable range when the painting head is painting a body, and a moving mechanism that moves the multi-axis arm in a painting direction when the painting head is painting the body.

This utility model proposes a suspended platform for bridges, comprising: a platform body, a swing arm, a damping wheel, and a spring rod. The platform body is suspended from the lower part of the bridge by steel cables. A guardrail is provided around the outer perimeter of the platform body, and a mounting base and an extension rod are provided on the guardrail. One end of the swing arm is hinged to the mounting base, and the damping wheel is mounted on the other end of the swing arm. One end of the spring rod is hinged to the end of the extension rod. This utility model, by setting a swing arm on the guardrail, presses the damping wheel against the bottom of the bridge under the action of the spring rod. When the platform body sways, the damping wheel rotates. The damper can resist the rotation of the damping wheel, converting kinetic energy into internal energy, allowing the platform body to quickly eliminate swaying. The swing arm's swing allows the damping wheel to adjust itself according to the curvature of the bridge bottom, adapting to different bridge types. The pressure of the damping wheel on the bridge is controlled by the spring rod to maintain appropriate pressure, preventing swaying while avoiding excessive pressure that could cause safety hazards.
