If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1 to 4, the pretreatment device for yarn knitting according to the present embodiment includes: a bracket 100; a heating means 110 provided at an upper end of the supporter 100; the first fan 140 is arranged at the lower end of the bracket 100, and the air outlet direction of the first fan 140 faces the heating device 110; a first front roller 120 rotatably connected to the bracket 100, the first front roller 120 being located between the heating device 110 and the first fan 140; a first rear roller 180 rotatably connected to the bracket 100, the first rear roller 180 being positioned between the heating device 110 and the first fan 140, the first rear roller 180 being positioned at the rear side of the first front roller 120; and a driving device disposed on the bracket 100, the driving device being configured to drive the first front roller 120 and the first rear roller 180 to rotate.

The driving device may drive the first front roller 120 and the first rear roller 180 to rotate in multiple ways, for example, a plurality of motors are disposed on the bracket 100 to respectively drive the first front roller 120 and the first rear roller 180 to rotate, or a pneumatic motor or a hydraulic motor is used to drive the first front roller 120 and the first rear roller 180 to rotate, or a single motor is used to cooperate with the transmission mechanism to simultaneously drive the first front roller 120 and the first rear roller 180 to rotate.

In the present embodiment, the first rear roller 180 is located between the heating device 110 and the first fan 140, which means that the height of the first rear roller 180 is higher than that of the first fan 140, and the height of the first rear roller 180 is lower than that of the heating device 110, and the first rear roller 180 is not necessarily located right below the heating device 110; the following similar expressions should be understood broadly by reference.

After most of the yarn is wound on the first rear roller 180, the first front roller 120 and the first rear roller 180 can be controlled to rotate reversely, so that the yarn is wound on one of the front rollers, the processed yarn is convenient to recover, the yarn is convenient to process repeatedly, and fluff on the yarn is fully removed.

It can be understood that, since the first front roller 120 is located between the heating device 110 and the first fan 140, during the production process, the heat generated by the heating device 110 flows upwards under the action of the wind blown by the fan, the yarn itself under the heating device 110 is rarely radiated by the heat of the heating device 110, and the fluff on the yarn is heated and shrunk only when directly contacting the heating device 110 itself under the action of the upward air flow, thereby further reducing the damage to the yarn itself.

Wherein, the heating device 110 can perform heating in various ways, for example, by the electric heating device 110, or the hot water circulation heating device 110, etc.; in order to avoid the yarn body from contacting the heating device 110 under the action of the ascending air current, thin heat insulation gaskets may be arranged between the yarn and the heating device 110 at intervals, so as to prevent the yarn body from contacting the heating device 110 while ensuring that fluff can contact the heating device 110.

As shown in fig. 4, the driving device includes at least two external rotor motors for driving the first front roller 120 and the first rear roller 180 to rotate, a stator 210 of the external rotor motor is disposed on the bracket 100, and a rotor 220 of the external rotor motor is disposed on the first front roller 120 and the first rear roller 180; all the rollers including the first front roller 120 and the first rear roller 180 are driven by an independent outer rotor motor, so that the rollers can rotate forward and backward independently.

As shown in fig. 4, the first front roller 120 and the first rear roller 180 are detachably and rotatably connected to the rotor 220 of the outer rotor motor; after production is finished, the first front roller 120 wound with the silk threads can be directly detached, the whole body is placed into weaving equipment for weaving, and the stator 210 and the rotor 220 can be conveniently separated due to the fact that the rotor 220 of the outer rotor motor is arranged on the outer side of the stator 210, and the first front roller 120 can be conveniently detached; similarly, the first rear roller 180 may also be directly removed after the last debulking to wind the yarn onto the first rear roller 180.

The pretreatment device for yarn weaving further comprises: a cooling device 160 disposed at the rear side of the supporter 100; the second fan 150 is arranged at the rear side of the bracket 100, and the air outlet direction of the second fan 150 is upward; the cooling device 160 is positioned below the first rear roller 180, and the second fan 150 is positioned below the cooling device 160; in the middle of the production process, the yarn is under the drive of first back gyro wheel 180, through cooling device 160 top, and the air that second fan 150 blown is behind cooling device 160, and its vapor that contains meets the condensation knot for it is lower to blow the air humidity on the yarn, can play the effect of dry yarn when cooling for the yarn.

The cooling device 160 may cool the air blown by the second fan 150 in various ways, so that the water vapor is condensed, for example, by a water-cooled heat exchange device to cool the air.

As shown in fig. 1, the pretreatment device for yarn weaving further includes a compressor 190, the cooling device 160 is an evaporator, the heating device 110 is a condenser, and the compressor 190, the evaporator and the condenser form a refrigerant loop; the heat absorbed by the evaporator can be used for heating the condenser, and the overall energy efficiency of the equipment is improved.

Wherein, an electric heating wire can be arranged on the condenser; at the beginning of starting the equipment, the temperature of the condenser of the heat pump system is slowly increased, and at the moment, the temperature can be quickly increased through the electric heating wire, so that the equipment can reach the production condition as soon as possible.

Specifically, the refrigerant in the refrigerant circuit is carbon dioxide; compared with the common R32 and R410, the carbon dioxide belongs to a natural refrigerant, the harm to human bodies is small after leakage, more importantly, the carbon dioxide heat pump belongs to supercritical circulation, and the exhaust temperature is higher, so that compared with a heat pump system using R32 and R410, the condenser can achieve a higher problem, and the shrinking effect is better when fluff contacts the surface of the condenser.

On the other hand, besides the heat pump system, a semiconductor heat exchange element may be used, where the heating device 110 is the hot end of the semiconductor heat exchange element, and the cooling device 160 is the cold end of the semiconductor heat exchange element; compared with a heat pump system, the semiconductor heat exchange element has small vibration noise and small influence on the field environment.

As shown in fig. 3, the method further includes: a second front roller 130 rotatably connected to the bracket 100, the second front roller 130 being located between the heating device 110 and the first fan 140; a second rear roller 170 rotatably coupled to the bracket 100, the first rear roller 180 being positioned between the heating device 110 and the first fan 140, the second rear roller 170 being positioned at a rear side of the second front roller 130; the driving device is used for driving the second front roller 130 and the second rear roller 170 to rotate; at this time, the two sets of rollers rotate simultaneously, so that at least two sets of yarns can be subjected to a pretreatment process.

Specifically, all gyro wheels are independently driven by single external rotor motor, when needs handle many coils of yarn simultaneously, can increase the quantity of preceding gyro wheel and back gyro wheel, improve production efficiency.

The embodiment also provides a pretreatment method for yarn weaving, which applies the pretreatment device for yarn weaving, and comprises the following steps: a loading step of winding the yarn to be processed around the first front roller 120 and fixing one end of the yarn to the first rear roller 180; and a processing step, controlling the driving device to drive the first rear roller 180 to rotate, so that the yarn is gradually wound on the first rear roller 180, and simultaneously starting the first fan 140 and the heating device 110 to blow the fluff on the yarn upwards, so that the fluff is heated and shrunk after contacting with the heating device 110.

In this embodiment, the up-down direction shown in fig. 1 is the plumb direction, and the horizontal plane is the plane in which the front-back direction and the left-right direction are located.
