A high-speed cutting device includes a mounting frame, a feeding mechanism, a linear chasing-cutting mechanism, an electrode guide plate, and an acceleration driving mechanism, the acceleration driving mechanism is provided on the discharging side of the electrode guide plate, and configured to perform acceleration driving on a material tape. The acceleration driving mechanism is provided behind the linear chasing-cutting mechanism to realize the acceleration driving of the material tape.

A cutting device includes a drum section that rotates to convey a continuous body, and a cutting section that cuts the continuous body into multiple individual works. The drum section includes multiple holding heads that move while holding the respective works. The cutting section includes a cutter unit that moves together with multiple holding heads and that is smaller in number than the holding heads, and a cutter drive unit that moves the cutter unit independently of multiple holding heads. The cutter unit moves alongside of the continuous body from a certain cutting start position to cut the continuous body. The cutter drive unit returns the cutter unit that has cut the continuous body, to the cutting start position.

A blade driving apparatus configured to drive a blade of a cutting device to cut a web and includes an anvil and a slide assembly. The slide assembly includes a slide rail and a slide block that are slidably connected to each other. The slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of the web. At least one of the slide rail or the slide block is made of a non-metallic material.

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 cutting unit in a packaging machine for separating a series of finished packages containing a predetermined number of products from a continuous packaging or bundle advancing on a conveyor, comprising a frame, which supports a pair of side cutting blades and a pair of upper cutting and lower cutting blades arranged facing four sides of the continuous bundle, wherein the two pairs of blades can be alternately moved forward and backward between a rest position separated from the continuous bundle, and an engagement position on the continuous bundle containing groups of the products arranged on two flanked rows and wrapped in a film of extendable plastic material, each pair of blades being driven in an alternating forward and backward movement for engagement with and disengagement from the continuous bundle by a double crank actuated by a single motor.

The invention relates to a connecting cut assembly for producing connecting cuts in a material web being conveyed. The connecting cut assembly comprises at least one knife device with a cutting knife for cutting engagement with the material web to produce a connecting cut in the material web. Moreover, the at least one knife device has an actuatable cutting knife angle adjusting device for setting a respective cutting knife angle of the cutting knife to the material web. The connecting cut assembly comprises at least one presetting unit for actuating the respective cutting knife angle adjusting device.

A processing apparatus is disclosed comprising a shearing unit that receives the material to be processed from a conveying device upstream and surrenders it to a conveying device downstream, in which the material to be sheared advances with a continuous supply motion, in which each conveying device comprises a variable geometry closed loop slidable flexible element, in which the shearing unit is constrained to move with alternating motion together with two movable portions of the two conveying devices. The apparatus can process web-shaped material for the production of electrical energy storage devices.

Disclosed is a cutting device and a method for cutting-off a length of a continuous strip to form a tire component, wherein the cutting device includes a cutting member for cutting the continuous strip at a cutting position and a feeding member that is movable in a feeding direction for feeding the length of the continuous strip in the feeding direction past said cutting position, wherein the feeding member is retractable in a retraction direction. The cutting device further includes a manipulator for retaining the length as the feeding member is retracted in the retraction direction, wherein the cutting position is located on the manipulator and wherein the cutting member and the manipulator are movable together in the feeding direction to cut-off of the length of the continuous strip at the cutting position on the manipulator while moving the length of the continuous strip in the feeding direction.

A device for cutting sheet metal plates out of a sheet metal strip includes a laser cutting device moving back and forth in a transport direction of the sheet metal strip and a y-direction running perpendicular to the transport direction, a first conveyor belt having first end moving back and forth together with the laser cutting device in the transport direction, a second conveyor belt having a second end opposite the first end and moving back and forth in the transport direction. The first and second ends are moved such that a laser beam generated by the laser cutting device is directed towards a gap formed between the first and second ends and extending in the y-direction. In order to avoid adhesions to an underside of the sheet metal strip, at least one support strip and/or the dust discharge shaft is provided with a ventilation device for ventilating the gap.
