Structure Composition and Function of Slitting Machine
Slitting machine is a kind of equipment for longitudinal slitting of wide rolls of materials, which is widely used in paper, leather, cloth, plastic, film, metal coil and other industries.
This article mainly introduces the structure composition and function of metal coil slitting machine.
1. Storage Table: used for the raw material to be processed storage, also known as raw material standby place, generally customized 1-2.
2. Transporting Roll Cart: the raw materials stored in the storage table are transported into the uncoiler, through the function of rising, falling, moving back and forth, etc., the raw materials are put into the uncoiler, usually by visual / manual, etc., can also be made into a fully automatic "V" plane or roll plane.
3. Uncoiler: usually single cantilever type, such as the weight of raw materials, the need to add auxiliary support at the end of the unwind tube. Uncoiler seat usually has a single parallel direction along the back-and-forth movement function, can effectively and quickly complete the alignment of raw materials, generally using visual / after moving the way, can also be made fully automatic alignment, but need to increase the cost.
A. Cone head type uncoiling frame: cone head type uncoiling frame is suitable for cone head to cone tail range of any inner diameter of the raw material, but because it is easy to cause damage to the edge of the inner circle of raw materials, generally applicable to 3mm or more in the thick raw material.
B. Step type uncoiling frame: this way of uncoiling head is only applicable to multi-standard inner diameter raw materials, generally divided into 2~4 levels, but the operation is relatively no single-headed cantilever intuitive and convenient, and its front and rear movement is usually driven by oil cylinder.
4. Clamping, Leveling and Plate Head Shear.
Clamp to the wheel usually use hydraulic, pneumatic and electric lifting devices.

4. Clamping, Leveling and Plate Head Shear.
Clamp to the wheel usually use hydraulic, pneumatic and electric lifting devices.
Leveling machine usually adopts electric lifting and worm gear structure to ensure the stability of lifting and positioning.
Plate head shear usually adopts hydraulic shear bed to ensure that the raw material into the end of the disc shear flush, and its drive is generally driven by stepless speed control motor to ensure the smooth synchronization of the whole machine line speed.
5. Live Set Pit (Loop 1): also known as raw material storage buffer pit, usually 2 to 4 meters deep, 3 to 4 meters long, as raw materials in the clip feed and slitting shear between the speed matching buffer device, usually using hydraulic electric lifting the transition platform, the raw materials into the clip feed and side guide position device, the transition table plate generally uses rollers and anti-scratch material as raw materials contact transition surface.
6. Side Guide and Clamping Device: side guide is used as the raw material in the rapid advance of the lateral positioning device, usually using the vertical roller type or vertical plate structure, to ensure that the raw material in the longitudinal shear of the horizontal positioning, not to run edge and cause poor shear width of the finished product; clamping device is generally used on the roller type, to ensure the flatness of the material before shearing.
7. Disc Shear: disc shear, also known as longitudinal shear, slitting, the core device of this production line, through the different combinations of blades and spacers to achieve the degree of cutting different finished width. Slitting machine slitting knife shaft precision requirements are very high, its longitudinal runout, lateral deflection and its mechanical strength are determined by the accuracy of the finished slitting. Slitting machine auxiliary parts round blade, blade spacer and other precision requirements also determine the accuracy of the finished slit and row of knife time, directly affecting the processing output. The rejection of the general way there are rubber ring rejection and pressure plate rejection of two, blade and blade spacer positioning nut positioning and more expensive hydraulic shaft lock and other ways.
8. Transition platform: transition platform is to cut the finished product transition to the finished live set of buffer pit device, the requirements of its and disc shear near the part can be lifted up freely, to facilitate the blade row group and finished product quality measurement and other functions, in the fixed part of the tail material pressure plate device to prevent the finished product shear after falling into the live set of pits to form a mess with knots.
9. Waste Side Winding Machine: waste side winding machine using disc type receiving device, the material shear waste side winding into bundles, in order to facilitate the storage and transportation of waste side wire, generally supplemented by screw-type guide device or cam linkage type guide device, its drive using stepless variable speed and tension control motor drive, supplemented by emergency stop brake brakes, manual unloading and automatic unloading two ways.
10. Finished Product Buffer Pit: length about 3~4 meters, depth depending on the material thickness, slitting strips and raw material roll diameter and other parameters, but the usual depth of about 4~7 meters. In the slitting and cutting of multiple thin plate material, due to the thickness tolerance of the original material and the tension of the tension production station is not uniform and other factors that cause the finished products of different lengths and other phenomena, the live set pit to speed buffer and set the amount of storage and other functions.
11. Front Separation Device: the front separation device is the finished product into the tension production station to give pre-separation separation, so that the finished product in the tension extrusion will not appear cross belt, overlapping belt phenomenon, generally by the two separation positioning and anti-jump belt pressure wheel composition, the front section can be lifted by the separation axis, can prevent the pressed plate due to the plastic deformation caused by the pressure wheel, separation axis using movable guide can be convenient and flexible separation axis sliding pull out, so as to facilitate the separation of the group.
