Description

A kind of heating slot of ironing machine

The present invention relates to a kind of heating slot of ironing machine, especially comprise the boiling hot groove structure of bridge floor hot type.

The industry ironing machine is used for occasions such as hotel, hotel, hospital, social laundry, is used to press the ironing equipment of cloth grass such as sheet, the tablecloth, bedcover (the laundry industry is to the general name of fabric).The structure of scalding groove and bridge floor hot type ironing machine is: comprise cylinder, scald groove (comprising preceding groove, bridge floor, pit), feeding, drawing mechanism.It generally is the structure of two cylinders.The cloth grass is sent into preceding groove by feed arrangement, after scalding through the pressure of first cylinder and preceding groove, is driven through Crossing the bridge noodles by guidance tape, scalds the back through the pressure of pit again and is sent by drawing mechanism.Preceding groove, bridge floor, pit are welded as a whole, T shape of its section constitution, and the cross section of bridge floor is the top of this T shape.The industry ironing machine is divided into the slot type heating and cartridge type heats two kinds.Slot type heating ironing machine is divided into vertical and horizontal two kinds again.Be meant that mainly scalding groove has vertical and horizontal branch.Vertical and horizontal ironing machine is compared, owing to scald the structure difference of groove, the ironing machine of same hot exchange power, the floor space of vertical ironing machine is much smaller than horizontal ironing machine.Boiling hot groove is a heater, by steam or initiatively heating of electricity.The position of the boiling hot groove of vertical ironing machine is higher, and the cloth grass is sent into when scalding groove, overcome gravity and frictional force moves upward; And the position of the boiling hot groove of horizontal ironing machine is lower, and the cloth grass is sent into when scalding groove, is to move downward under the gravity effect.Therefore, vertical ironing machine is compared with horizontal ironing machine, and easier appearance ironing defective is had higher requirement on boiling hot groove design, processing and complete machine structure.

Overwhelming majority hotel, hotel and other society's laundry occasions all use steam to be thermal source.At present, domestic steam pressure is generally at 0.4.7Mpa, even lower.The operation principle of slot type heating ironing machine is: the cloth grass is subjected to three power effects after entering boiling hot groove: the one, and the frictional force that the cylinder surface felt makes progress to the cloth grass, the 2nd, scald rooved face to the downward frictional force of cloth grass, the 3rd, the deadweight of cloth grass.When cylinder to the frictional force of cloth grass greater than scalding groove to the frictional force of cloth grass during with cloth grass deadweight sum, the cloth grass just can be continuously, normally press; Otherwise the cloth grass can not normally move upward along scalding groove, and follow-up cloth grass is continued to carry by input unit, and the situation of clot will appear in cloth grass front end, promptly so-called " volume is single " defective.When serious, the cloth grass will be rolled into the rod shape, even tear.Groove type ironing machine can operate as normal, mainly be rely on to scald groove enough temperature are arranged, when the cloth grass that contains moisture enter scald groove after, between boiling hot rooved face and cloth grass, form one deck steam blanket immediately, reduced the frictional force of the careless and boiling hot rooved face of cloth.After moisture cloth grass entered boiling hot groove continuously, the temperature of scalding the groove porch can sharply descend, and after temperature was lower than 100 ℃, the cloth grass can not form steam blanket immediately after entering boiling hot groove, and the frictional force between cloth grass and the boiling hot groove sharply increases, and causes above-mentioned ironing defective.When steam pressure was low, the ironing defective of horizontal wrinkle also can appear at the postmedian of cloth grass sometimes.

The boiling hot groove of traditional vertical groove type ironing machine, forward and backward groove adopts same heating arrangement, and bridge floor does not have heater, the heat radiation of groove before and after utilizing fully.And in separating draining experiment (test of condensed water discharge capacity), the displacement of preceding groove accounts for 65% of total displacement, bridge floor accounts for 10%, pit accounts for 25%, before the displacement of groove inlet (before accounting for 25% of the groove heated length) account for 40% of total displacement, therefore be not difficult to find out that the cloth grass is in the process process of whole boiling hot groove, transpiring moisture is very uneven.The heat exchange amount of preceding groove is about 2.5 times of pit, and it obviously is irrational that the front and back groove adopts identical heating arrangement.In addition, bridge floor does not have heating arrangement, the heat conduction of complete forward back groove face obtains heat, in the experiment of light groove thermometric, under the 0.4Mpa steam pressure, bridge deck temperature has only 105 ℃, when pressing continuously, heat conduction velocity is far smaller than the lost speed of bridge floor heat, makes bridge deck temperature far below 100 ℃, does not have effect substantially for the moisture in the evaporation cloth grass.In addition, cross when low, can increase the resistance of cloth grass, the ironing defective occurs from the bridge floor process when bridge deck temperature.And the heated length of bridge floor accounts for 1/3 of whole heated length, and therefore, increasing heater on bridge floor is heated length, the raising ironing speed of effectively utilizing bridge floor, the effective ways that improve bridge floor ironing effect.The thermal design that adds that horizontal groove type ironing machine scalds groove also has similar defective, porch heat supply deficiency.

The objective of the invention is: a kind of heating slot of ironing machine is provided, makes ironing machine adapt to the condition of work of low vapor pressure, volume list, horizontal wrinkle etc. do not occur and press defectives, and work under the condition of cloth natural plant height moisture content can adapt to low vapor pressure the time in when work.The present invention also aims to further improve ironing speed, improve the ironing effect, further improve the ability to work of slot type (especially vertical) ironing machine under low vapor pressure.

The object of the present invention is achieved like this: a kind of heating slot of ironing machine, and groove and bridge floor are formed before and after comprising, and front and back groove and bridge floor are one, and by steam heating, it is characterized in that the thermal conduction plate that adds with the independent steam supply heating of being provided with of preceding groove porch.

Further improvement of the present invention is: for overcome when steam pressure lower, when cloth grass moisture content was higher, the too late situation of heat supplement still can appear in preceding groove porch, the result of performance rolls up list exactly.The cross sectional shape of vertical heating slot of ironing machine constitutes a T shape.Therefore, further improving in the design, two of preceding groove porch are being added thermal conduction plate carried out further reinforcement heat supply and improve.With two original guide plate one tunnel admission, change the admission respectively of two guide plates into, porch first guide plate steam inlet pipe dimension D N25, the steam inlet pipe dimension D N20 of second guide plate.

Further improvement of the present invention also comprises: the heated length of bridge floor accounts for and scalds 1/3 of the total heated length of groove, therefore, has increased on bridge floor and adds thermal conduction plate, effectively utilize bridge floor heated length, improve ironing speed, improve bridge floor ironing effect.

Characteristics of the present invention are: adopt the present invention to scald the ironing machine of groove, can ironing defectives such as volume list, horizontal wrinkle can not occur in operate as normal under the low vapor pressure (less than 0.4Mpa).Work under the condition of cloth natural plant height moisture content when also adapting to low vapor pressure.Improve ironing speed, improved the ironing effect, further improved the ability to work of groove type ironing machine under low vapor pressure.The main improvement according to being the cloth grass when scalding groove, the lack of uniformity of transpiring moisture has been carried out the lack of uniformity design to the heating arrangement that scalds groove is corresponding.
