The end of the first mandrel and the end of the first outer shaft are each provided with a first transmission part coupled to a drive device; the blades are respectively arranged in the shaft assembly and perpendicular to the rotating shaft assembly; one blade is coupled to the first mandrel, and the other is coupled with the first outer shaft, so that the blades can be driven by the rotating shaft assembly to rotate in two opposite directions at the same time. The fruit and vegetable cutter includes a fruit and vegetable cavity, the cutter assembly and a driving device for driving the cutter assembly.

A cutting device for cutting an initial product into a plurality of products comprises a base, a cutter seat and a cutter. The initial product includes an insulator and a plurality of groups of terminals fixed on the insulator. The base of the cutting device includes a plurality of slots arranged side by side, and a first positioning slot formed on an inner sidewall of each of the slots of the base and adapted to position one of the terminals of the initial product. The cutter seat is inserted into one of the plurality of slots and defines a blade slit. The cutter is adapted to be inserted into the blade slit to cut off the insulator of the initial product to form the product.

Existing blade assemblies for cutting complex three-dimensional shapes such as twisted shapes are typically slow and suffer from frequent breakdowns. Disclosed herein is a stationary blade assembly for cutting food products into complex shapes as the food products are directed along a direction of flow at the blade assembly, wherein the blade assembly comprises a plurality of blades, each of the plurality of blades having a length, wherein the length of the blade is oriented along the direction of flow and the blade is twisted along its length, whereby the food products are rotated by the blade during cutting.

A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a moveable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

A drag knife apparatus for cutting stencil patterns in sheet material comprises a drag knife holder biased downwardly into cutting position by a variable tension spring and lifted out of cutting position by a relay-controlled solenoid. The knife holder is counterweighted through a lever arm. The apparatus can be used to form a sandblasting stencil from material adhesively held in position on the face of a monument during the stencil cutting process. The stencil is removed after the sandblasting step.

The invention relates to a perforating device for thermoplastic plates, which relates to the technical field of a plate processing device. The device includes an electromagnetic chuck, one side of the electromagnetic chuck is connected with the driving member, the other side of the electromagnetic chuck is connected with a mounting plate and a spike. When the electromagnetic chuck is powered on, the spike is attracted below the mounting plate by an electromagnetic force generated by the electromagnetic chuck. A damper is arranged below the mounting plate, the thermoplastic plate is fixed by the damper, and a heating system is also provided to heat the thermoplastic plate. As the electromagnetic chuck is powered on or off, the spike can be attracted in or separated from the mounting plate, respectively. Therefore, the perforating device can make a new plate be pierced during the cooling and curing process of the perforated plate.

This application relates to a fixed blade monitoring structure and a cutting device used for lithium battery manufacturing. The fixed blade monitoring structure includes: an anvil, fixed blade die set, and a fixed blade monitoring assembly. A sliding sleeve is disposed on the anvil. The fixed blade die set includes a fixed blade holder and a fixed blade mounted on the fixed blade holder. An end of the fixed blade holder is slidably mounted in the sliding sleeve. The fixed blade monitoring assembly is mounted in the sliding sleeve and connected to the fixed blade holder, and configured to render status of the fixed blade by monitoring a relative force received by the fixed blade holder. Through the above structure, manpower and time consumption in the tuning process is reduced. The status monitoring of a first cutter and a second cutter can be implemented during the cutting.

A cartridge adapted to secure reciprocating bread slicer blades including a rectangular frame having a planar surface, the frame having a plurality of pairs of opposed holders, each pair of the opposed holders adapted to releasably secure opposed ends of a corresponding bread slicer blade. The frame is adapted to secure a plurality of aligned bread slicer blades defining a plane offset from the frame planar surface. The frame is adapted to selectively maintain each of the plurality of aligned bread slicer blades in tension.

A food product slicing apparatus is configured to slice food products into slices. A load assembly pivotally is mounted on a frame and a food product is positioned thereon. A drive assembly on the frame receives the food product from the load assembly and moves the food product relative to the frame. The load assembly can be positioned in at a first, lowered position relative to the drive assembly, a second, partially raised position relative to the drive assembly and a third, fully raised position relative to the drive assembly. The drive assembly engages the food product when the load assembly is in the third, fully raised position.
