Description

Winding apparatus with the tenslator for flat film

Technical field

The utility model belongs to food service industry, and more specifically belongs to the casing for sausage and meat products.Specifically, The utility model relates to the winding apparatus with tenslator with for will be intended to fill food flat tubulose casing into Row winding.

Background technique

During producing the casing or film based on fibrous type polymer material and especially in production for filling food During the tubular film of product, subsequent processing is carried out for its storage and is converted to the ruler suitable for heterogeneous expectations purposes The purpose of very little product unit, finished-product material are finally wound (winding).

By squeezing continuous and tubular the flexible pipe formed by means of such as example by motor actuated pairs of folder It holds axis direction of the tension force effect unit of roller when applying tension on the flexible pipe along the flexible pipe linearly to convey, tension is made Pipe is set to become flat when pipe passes through with unit, thus to provide in the flat pipe that becomes of flat strips or flat band forms Mouthful, the flat width of the outlet is identical as the half of the perimeter of the pipe of form cylindrical in shape.Film passes through the path along the film A series of tension of similar units is delivered to winder station, so that a series of tension are produced in film, and described a series of Power must be kept in a certain range, with will not stretched film will not make film become loose too much at any time.It is rolling up In region, the last tension element on film is volume itself, that is to say, that is the motor torsional moment applied by the axis rolled up.

The volume of material must be subjected to the regulating step in some opposite later periods for example sometimes before being converted into consumable unit To obtain its water content, perhaps it is subjected to other physical processes or is subjected to such as temperature adjustment processing.In other cases, material It rolls up before the unit for being converted to be handled by consumer, other than other processing, the volume of material must be printed, do Dry, coating, lamination, perforation.The unit almost always individuation section of production tube, these individuation sections may finally be by Suture, clamps, tying and is linked to be string, rolls up and substantially crimp and compress in a tubular manner bonding, to form small bar Shape part.

Therefore, the volume of material is the load-bearing part of material, and in some cases, the volume of material can be in the case where not unwinding Be subjected to some processing to it, and in other cases, the volume of material must unwinding will be received finally with supplying to material It the station of processing and even needs to rewind in the intermediate steps before it is typically converted into the final conversion of rod-like element.

In the case where directly handling volume, volume needs to have well-regulated shape (that is, shape is not eccentric Or the layer of material will not be moved relative to each other and form recessed volume or flexible volume), and it is multiple to constitute being divided into for volume The material of ring keeps uniform density.

Density is derived from the tightness degree between the layer of the coiling of central axis constituent material, and density must be uniform , allow any processing to be equally related to all winding materials.For example, if volume must be subjected to be heat-treated, Huo Zheru Fruit volume preferably must be held in for example to obtain a degree of moisture in specific atmosphere, then compactness degree is crucial.Similarly, If volume winds or is already coated with the material sensitive to excess pressure in a manner of with a degree of moisture, Non-uniform compactness, which will lead between the intensive or pantostrat of pressurized zone, there is bonding situation, this is in processing step later Suddenly, such as it will lead to many problems in unwinding.In addition, volume will the case where irregularly winding in a manner of aforementioned deformation In unwinding, for example to be printed, be coated or when lamination treatment leads to the problem of.

Winding tension is most critical, and reason is that material has its maximum cluster set or assembles close to its maximum at this time Value, and volume must correctly wind in order to carry out subsequent delivery and processing to it.

Unwinding and the tension rewound in region are very dynamic.The diameter of roller constantly changes, therefore motor Torque and speed must constantly be adjusted with the diameter change of roller.

If band becomes loose since tension is insufficient, band will wrinkle and may be snarled.If overtension, Stretch marks, gauffer and possible breakage will be then generated in band.In both cases, second-rate product can be produced simultaneously And machine efficiency is not high.

Therefore, it is necessary in view of control volume compactness, before being reeled up setting ensure density of material uniformity and The tension automatic control system of the film of the correct three-dimensional structure of volume is vital.

There is several methods to can be used for keeping constant tension.Most commonly: the follower of the diameter of volume calculates volume The forecasting system of diameter, float (bounce) roller and tension transducer (load transducer).

Motor torsional moment needed for providing the tension of certain level for band is the total tension measured by the radius of turn of band.This It is meant that in order to keep constant tension, by rewind axis promote torque in up- coiler must relative to roller diameter with Linear relationship increases, because the size for rewinding roller increases during the operation of machine.

The calculating of motor torsional moment is defined by expression formula TQ=R × T；The equation be it is linear, therefore, if tension (T) to be kept constant according to expression formula T=TQ/R, then motor torsional moment must be with half in the winding that the radius of volume increases Diameter (R) linearly increases.Therefore, if radius increases such as 10 times, torque will be also required to increase 10 times to keep tension permanent It is fixed.

However, when circumvolution around when, the tired compressing force of each lamination will lead to interior layer and fold to core.If these are compressed Power becomes much larger, then will generate corrugation and become flat core.It, can be in tension force in order to mitigate these compressing forces Some tension forces in execute the adjusting for being referred to as " taper tension ", taper tension enables the tension of band with the expansion of volume And reduce.The amount of taper tension is typically measured as the percentage of tension adjusted.For example, if taper tension is adjusted to 50%, then tension will linearly outward reduce from core, and therefore, the tension outside roller will reach the half of the tension of core.

It come the device for controlling tension is floating based on the actual tension in band in the above-mentioned device for keeping constant tension Dynamic (bounce) roller and load transducer.These are " closed loop " control.Closed-loop control is point-device, because closed-loop control is practical Upper measurement is the tension in and controls discoid pieces, to keep constant tension relative to the point established.Both types Device will compensate such as tension variation due to caused by the diameter change of roller when roller is rewound.The device of both types The tension variation due to caused by accessory, bearing, mechanical loss and appointing in the power of machine direction effect on tape will also be compensated Tension variation caused by He Li.Nevertheless, these control devices can not be in the case where no external entrance due to being closed loop The diameter of measuring roll, therefore, their own cannot provide taper tension for the application in wrapping range again.

Load transducer has converters.Converter in load transducer is mentioned based on existing mechanical force The detecting element of power supply signal.The power transmitting also included in the future other than supporting and protecting converter of the shell of load transducer To converters.Output signal is transferred to adjuster and is passed to observation device and tension-adjusting gear in the regulators (thus controlling motor or clutch).

Load transducer tension controller is measured due to tension using tensometer and other Weight-measuring devices and is applied " weight " on idler roller (not being pulled).The power on idler roller and the material are applied to due to the tension in material around the roller Circular angle it is proportional.Load transducer tension controller can work under at most 180 ° of any circular angle.Around making It cannot be changed according to the variation of the diameter of roller with the circular angle of the free roll of load transducer；Therefore, these controllers make With input deflector roll and output deflector roll.

The operator of machine establishes required tension.Based on the design of roller/load transducer --- roller/load transducer Design depends on the width for the band advanced in the machine again, can be in the two sides of idler roller or the generation measurement letter at a single point Number, and the signal is introduced into control unit or adjuster.Adjuster handles the signal together.By processing costs Output is compared and generated with the value established, and the output is sent to speed changer to keep constant tension.

The objective of the equipment of the utility model is the automatic control of the tension of finished film in winding steps, it is therefore an objective to be formed The complete concentric volume of certain compactness degree with the material for being suitable for manufacturing film.
