Description

Technical Field

[0001] The utility model relates to the field of dyeing and finishing equipment, in particular to a soft finishing machine. Background Art

[0002] Softening finishing refers to the process in which textiles undergo wet heat treatment with various chemicals and are subjected to mechanical tension during the dyeing and finishing process, which not only causes the structure of the textile to deform, but also causes the hand to feel stiff and rough. Softening finishing is a processing process that compensates for this defect and makes the fabric feel soft.

[0003] The Aile Super Softening Machine, manufactured by Italy's Biancarani Textile Machinery Co., Ltd., is a world leader in this process. Its softening principle utilizes the pneumatic principle of a Venturi tube. A heated airflow is introduced into the tube, drawing the fabric in and kneading it under acceleration. The fabric then expands under decompression as it exits the Venturi tube. Finally, it is moderately impacted and tumbled upon impact with the grid. These three softening steps are accomplished instantaneously, with the fabric's movement driven entirely by the airflow, avoiding the compression and friction that might be caused by mechanical transmission. The boundary layer formed on the inner wall of the Venturi tube provides ample cushioning protection for the fabric, resulting in a powerful yet gentle treatment. However, each Venturi tube of the prototype requires a high-pressure blower (usually a Roots blower) to provide compressed air. The wind pressure and air volume of the (Roots) blower are limited by the large volume of the softener, resulting in the wind pressure and air volume being insufficient to achieve the technical effect that the prototype wants to achieve. In addition, the high-pressure blower has high power and high energy consumption, which also leads to high production costs and unsatisfactory and unsatisfactory effects, thus restricting the promotion of softening machines.

[0004] In view of the defects of the softening finishing machines currently on the market, it is urgent to develop a high-efficiency and energy-saving physical softening equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a soft finishing machine.

[0006] The technical solution for achieving the purpose of the utility model is: a soft finishing machine, which includes a positive and negative pressure generating unit and two cloth rolling bins, the two cloth rolling bins are arranged opposite to each other, and the cloth rolling bins are provided with bin doors; a reeling and unreeling mechanism is installed in each cloth rolling bin, and the reeling and unreeling mechanism includes a reel, and the two reels are arranged in parallel, and a cloth outlet is respectively provided on the opposite sides of the two cloth rolling bins along the axial direction of the cloth rolling bin, and the two cloth outlets are connected by a cloth passing channel, and the height of the cloth passing channel is limited to the fabric being able to hit the inner wall of the cloth passing channel under the disturbance of air; the positive and negative pressure generating unit includes a pressure generating cylinder, a piston and a rotating shaft, and the top of each cloth rolling bin is sealed and fixed with a pressure generating cylinder, and the pressure generating cylinder and the pressure generating cylinder are connected to the pressure generating cylinder. The cloth winding bins on the same side of the cylinder are connected, and a piston is installed in each of the pressure generating cylinders. The rotating shaft is installed between the two pressure generating cylinders, and an eccentric wheel is installed at each end of the rotating shaft. Each piston is connected to the eccentric wheel through a connecting rod. The eccentric wheel is eccentrically provided with a protrusion, and the two ends of each connecting rod are hinged to the piston and the protrusion on the same side. The initial positions of the protrusions of the two eccentric wheels are limited to the opposite running directions of the two pistons when the rotating shaft rotates. The rotating shaft is connected to the driving motor that drives the rotating shaft to rotate; a grid baffle is installed at each cloth outlet, and the length direction of the grid baffle is arranged parallel to the axial direction of the reel, and a cloth-passing gap is left between the grid baffle and the cloth outlet.

[0007] Furthermore, a plurality of protrusions are provided on the inner wall of the cloth passing channel.

[0008] Furthermore, the cloth passage has a meandering serpentine structure.

[0009] Furthermore, more than two positive and negative pressure generating units are installed between the two cloth winding bins, the positive and negative pressure generating units are arranged in parallel, and the rotating shafts are connected to the driving motor via a synchronous pulley assembly.

[0010] Furthermore, a cloth guide roller is installed in the cloth passing gap.

[0011] Furthermore, a centering device is installed between the reel and the cloth guide roller to assist the fabric in running flat.

[0012] Furthermore, the machine also includes a humidifier for generating high-temperature water mist. The humidifier comprises a housing and a heat source, a water mist nozzle mounted within the housing, and the housing is in communication with the fabric roll chamber. After being heated and humidified, the air is carried away by the air flow in the two cavities of the main unit. Fabric processed under certain temperature and humidity conditions achieves improved softness, while the effect lasts longer at room temperature.

[0013] Furthermore, the housing is located below the cloth rolling bin, and the cloth rolling bin is provided with a water mist through hole communicating with the interior of the housing. The humidifier is installed below the housing to prevent water vapor from forming droplets and flowing into the body, and is conducive to heating the heating tube.

[0014] Furthermore, a radiator is installed below the water mist nozzle, and the radiator is connected to the heat source; the heat source uses thermal oil or steam, which is heated by the radiator, and the temperature range is within 150°C. The humidity is humidified by spraying water mist on the radiator, which is connected to the main unit with multiple openings to provide humidity and temperature, and must be set at the bottom of the main unit with the nozzle facing downward to prevent water from directly wetting the cloth.

[0015] Furthermore, a sensor for detecting the temperature and / or humidity in the cloth rolling bin is installed in the cloth rolling bin.

[0016] Furthermore, an air filter tube is provided between the two cloth winding chambers, the air filter tube being in communication with the two cloth winding chambers, and an air filter and a one-way valve installed in the air filter tube. The one-way valve opens and closes according to the airflow in the chamber to filter out fluff and other fluff particles generated by friction of the fabric during operation of the softening machine.

[0017] Furthermore, two air filter tubes are arranged in parallel between the two cloth rolling bins, each of the air filter tubes is connected to the two cloth rolling bins respectively, and an air filter and a one-way valve are installed in the air filter tube, and the one-way valves of the two air filter tubes are in opposite directions.

[0018] Furthermore, a hook for hanging the cloth roll is installed in any one of the cloth rolling bins, and the hook is located above the reel to facilitate cloth loading.

[0019] The softening finishing machine realized by the present invention utilizes the positive and negative pressure generating unit connected to the cloth roll bin to truly realize the positive and negative pressure changes in the cloth roll bin. Since the volume of air directly driven to be compressed or negatively expanded inside the piston cylinder is very large relative to the working volume of the softening machine, the energy conversion rate is higher than that of other types of fans, so it can generate higher air pressure and wind speed that the Italian prototype cannot achieve, and the energy consumption is very low; the cloth roll bin and the flat cloth passing channel structure are smaller in size than the traditional finishing machine, which greatly saves heating energy; at the same time, there are more intense positive and negative pressures in the cloth passing gap The high wind speed increases the running speed of the fabric due to the narrow wind area. The fabric hits the grid fence and the friction with the inner wall of the cloth passage is high and frequent. The two cavities have two large-scale positive and negative pressure environments, one positive and one negative, to ensure the conversion of high and low pressure spaces of the fabric, which can meet the needs of airflow to achieve industrial purposes. The fabric is disturbed back and forth by the airflow generated by the piston, and the pressure on the fabric changes dramatically. The fabric is rubbed and hit by the grid baffle and the cloth passage, resulting in a loose and soft effect, which truly realizes the process effect proposed by the prototype.

[0025] Two positive and negative pressure generating units 1 are installed between the two cloth winding bins 2. The two positive and negative pressure generating units 1 are arranged in parallel. The positive and negative pressure generating units 1 include a pressure generating cylinder 11, a piston 12 and a rotating shaft 13. The top of each cloth winding bin 2 is sealed and fixed with a pressure generating cylinder 11. The pressure generating cylinder 11 is communicated with the cloth winding bin 2 on the same side of the pressure generating cylinder 11. A piston 12 is installed in each pressure generating cylinder 11. The rotating shaft 13 is installed between the two pressure generating cylinders 11. An eccentric wheel 14 is respectively installed at both ends of the rotating shaft 13, and each piston 12 is connected to the eccentric wheel 14 through a connecting rod 15. A protrusion 141 is eccentrically provided on the eccentric wheel 14, and the two ends of each connecting rod 15 are respectively hinged to the piston 12 and the protrusion 141 on the same side. The initial positions of the protrusions 141 of the two eccentric wheels 14 are limited to the opposite running directions of the two pistons 12 when the rotating shaft 13 rotates. The two rotating shafts 13 are connected to the drive motor 17 through a synchronous pulley assembly 16.

[0026] Furthermore, a humidifier 7 for generating high-temperature water mist is installed under any one of the cloth rolling bins 2. The humidifier 7 includes a shell 71 and a heat source (not shown). The shell 71 is spherical, and a water mist nozzle 72 and a radiator 73 are installed in the shell 71. The water mist nozzle 72 is located above the radiator 73. The heat source is connected to the radiator 73. A water mist through hole 25 communicating with the interior of the shell 71 is opened on the cloth rolling bin 2. A sensor 8 for detecting the temperature and humidity in the cloth rolling bin 2 is installed in the cloth rolling bin 2.

[0027] Furthermore, two air filter tubes 9 are arranged in parallel between the two cloth rolling bins 2, and each air filter tube 9 is connected to the two cloth rolling bins 2 respectively. A one-way valve 91 and an air filter 10 are installed in the air filter tube 9, and the one-way valves 91 of the two air filter tubes 9 are in opposite directions.

[0028] The working principle of the soft finishing machine implemented in this embodiment is as follows:

[0029] 1) Cloth loading: Open the warehouse door and transfer the cloth roll 100 to the hook 22. Then, pull the fabric 200 on the cloth roll 100 onto the reel 31 and start the reeling and unreeling mechanism 3 to wind the fabric 200 onto the reel. Then, pull the cloth head of the fabric 200 through the centering device 6, the cloth feeding gap between the cloth guide roller 5 and the grid baffle 4, the cloth feeding channel 24, and the cloth feeding gap of the cloth winding warehouse 2 at the other end, and then wind it onto the reel 31 of the cloth winding warehouse 2 at the other end. The length of the fabric between the two reels 31 exceeds the distance between the two reels 31 to form the stock of fabric, and the cloth loading is completed.

[0030] 2) Softening operation: start the drive motor 17, which drives the rotating shaft 13 to rotate through the synchronous pulley assembly 16, and then drives the eccentric wheels 14 at both ends of the rotating shaft 13 to rotate. The eccentric wheels 14 drive the piston 12 to reciprocate up and down along the axial direction of the pressure generating cylinder 11, thereby realizing the change of wind pressure in the two cloth winding bins 2; at the same time, the rewinding and unwinding mechanisms 3 in the two cloth winding bins 2 intermittently rotate forward and reverse, so that the fabric 200 reciprocates through the cloth channel 24. During the reciprocating motion, there is always enough cloth stock between the two reels 31. The fabric 200 repeatedly collides and beats on the inner wall of the cloth channel 24 and the grid baffle 4. During the softening process, the temperature range in the cloth winding bin is controlled within 150°C, and the water mist nozzle 72 sprays water mist on the radiator 73 to humidify the fabric, making it softer and fuller.

[0031] 3) Dust removal: During the operation of the positive and negative pressure generating units, the one-way valve 91 automatically opens and closes as the wind direction in the chamber changes. When the air flows through, the air filter 10 can filter out the short fluff and other feather particles generated by the friction of the fabric when the softening finishing machine is working.

[0032] 4) Fabric discharging: The fabric discharging operation is opposite to the fabric loading operation.

[0033] The inner wall of the cloth passage of the utility model is provided with protrusions or is provided as a serpentine channel as needed. As long as the height of the cloth passage is limited so that the fabric can hit the inner wall of the cloth passage under the disturbance of the air, the friction and hitting between the fabric in the cloth passage and the inner wall of the cloth passage can be achieved. However, a certain number of protrusions can increase the frequency of hitting and colliding between the fabric and the cloth passage, thereby improving the softening effect. Usually, the protrusions are made of plastic material, which can simulate the friction of the fabric to obtain a softening effect.

[0034] The number of the positive and negative pressure generating units can be customized according to production needs. The rotating shafts of each positive and negative pressure generating unit can be driven to rotate by a driving motor respectively, but the synchronization is better when each rotating shaft is driven to rotate by a driving motor through a synchronous pulley. This is a conventional technical means in the mechanical field and will not be elaborated here.

[0035] The cloth-passing gap can be equipped with a cloth guide roller as needed to guide the direction of the fabric and prevent high-pressure wind from blowing the fabric onto the slit wall below, causing it to run close to the wall and affect the shaking effect.

[0036] The centering device of the utility model can be installed as needed, and the centering device can play a role in assisting the fabric to run flat.

[0037] The humidifier is set according to needs. After the air is heated and humidified, it is carried away by the air flow in the two cavities of the main unit. The fabric processed under certain temperature and humidity conditions has better softness, and the effect is more lasting at normal temperature. The humidifier is installed under the shell to prevent water vapor from forming water droplets and flowing into the body, and is beneficial to the heating of the heating tube. The shell is spherical, which is conducive to bearing pressure without deformation. The heat source can be thermal oil or steam, which is heated by a radiator, or an electric heating tube can be installed in the shell.

[0038] The air filter tube and air filter are set as needed, and the one-way valve is opened and closed according to the air flow in the bin to filter and remove the short fluff and other feather particles generated by the friction of the fabric when the softening finishing machine is working; the number of air ducts is not limited, and when the directions of the one-way valves in different air ducts are opposite, air filtration in two directions can be achieved; the one-way valve is a conventional mechanical structure that is only conductive in one direction and cuts off in the reverse direction, and will not be described in detail here.

[0039] A hook for hanging a cloth roll is installed in any one of the cloth rolling bins, and the hook is located above the reel to facilitate cloth loading and unloading.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
