The invention relates to a tool for testing bobbin coil binding power and a method therefor. The tool comprises a guide rail base (1), a first suspended rod (2), a first lock screw (3), a load (4), a bobbin coil (5), a central spindle (6), a second lock screw (7) and a second suspended rod (8). At the tangential direction of the outmost coil layer of the bobbin coil (5), the load (4) is hung on a self-adhesive varnished wire at an end of the bobbin coil (5), the weight of the load (4) is increased gradually until the self-adhesive varnished wire on which the load (4) is hung is separated from the bobbin coil (5), and then the weight of the load (4) is a binding power value of the outmost coil layer of the bobbin coil (5). Through results of coil binding power testing, heating temperature and heating time in heat bonding process parameters can be adjusted, and therefore binding power values of bobbin coils can be quantified and controlled.

An improved seal and stabilizing system for a piston head in a tank cylinder provides a better mechanism for discharging and wiping a cylinder when heavy liquids such as chocolate or peanut butter are being dispensed. The seal system now includes a free-floating block inside the seal and grooves in the inner lower part of the hollow seal. The block and grooves keep the upper, outer part of the seal from deforming away from the inner surface of the cylinder that facilitates complete discharging and wiping of the material from the cylinder tank. The tensioning mechanism of the seal is made from a unitary and annular ring T-ring that easily slides on the rear surface of the piston head. In order to stabilize the movement of the piston head down the cylinder, clockwise and counterclockwise springs are provided for the stabilizing shoes. The dual spring arrangement prevents coil binding of the springs. The springs and stabilizing shoes maintain the piston head cross section parallel to the cross section of the cylinder.

The invention discloses a coil car, comprising a car body, a walking mechanism, a lifting seat and a lifting cylinder, wherein the walking mechanism is arranged on the car body; the lifting seat is arranged above the car body; and the lifting cylinder is fixed at the middle of the car body and controls the lifting seat to lift. The coil car is characterized in that the top of the lifting seat is V-shaped; two lining boards are respectively fixed at two opposite V-shaped inclined planes; and a gap required by a coil binding strip is preserved between the two lining boards on the two inclined planes. A large lifting stroke of the V-shaped lifting seat can be achieved; and the arranged lining boards not only play a role of protecting the finished strip, but also are convenient to bind the coil or dismantle the binding strip. The whole coil car is easy to manufacture and install, hollow in foundation pit, suitable for hot rolling of the coil and cold rolling of the coil, suitable for production lines such as a pickling line, a cold mill unit and a rewinding unit, and wide in application; the foundation construction is reduced; and the cost is also reduced.

A book binding machine has a page-forming mode and a spiral-binding mode, where a curved inexpensive piece of binding spiral coil or a convex member form a collection of pages being bound into a concavity on the spine of the pages to be bound with a proper pitch angle to accept insertion of a plastic spiral binding coil. An optional pivoting page-forming carriage and an optional pivoting cutter / crimper are respectively movable between engaged and disengaged positions. The book forming bar is optionally moved out of the way in an intermediate position while the spiral is spun into the perforations. Then the brackets place the cutter bar in position. Pulsed air is preferably used to operate the vibrator and the exhaust pulsed air is fed to a page aerating manifold to keep pages from clinging to each other prior to the sheets being clamped before insertion of the plastic spiral coil.

The invention discloses a gradient coil design method combining functional and simulated annealing algorithm, which is characterized in that it includes the following steps: step 1: constructing the basis function of the flow function according to the skeleton shape of the gradient coil; step 2: according to the preset parameters Construct the functional, and solve the extremum of the functional to obtain the current density distribution; Step 3: Construct the objective function for the actual coil structure, and further optimize the initial solution obtained by solving the extremum of the functional using the simulated annealing algorithm, and the obtained The results are used as the basis for the final gradient coil wiring.
