DETAILED DESCRIPTION
[0019] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work also belong to the protection scope of the present application.
[0020] The present application provides a cloth pre-shrinking machine, and the following embodiments will be described in detail.
[0021] The cloth pre-shrinking machine provided by the present embodiment, such as Figures 1 to 5As shown, the humidification mechanism 1 comprises a first centrifugal turntable 11 and a second centrifugal turntable 12; the first centrifugal turntable 11 and the second centrifugal turntable 12 are arranged in a first direction; one side of the first centrifugal turntable 11 is provided with a first supply pipe 13, and the liquid in the first supply pipe 13 can drop onto the first centrifugal turntable 11; one side of the second centrifugal turntable 12 is provided with a second supply pipe 15, and the liquid in the second supply pipe 15 can drop onto the second centrifugal turntable 12.
[0022] In the first direction, the first centrifugal turntable 11 and the second centrifugal turntable 12 are arranged in a first direction, and the cloth 8 is arranged between the first centrifugal turntable 11 and the second centrifugal turntable 12; the first centrifugal turntable 11 is arranged on the outside of the front of the cloth 8, and the second centrifugal turntable 12 is arranged on the outside of the back of the cloth 8.
[0023] The first centrifugal turntable 11 is driven by a driving device, and the first centrifugal turntable 11 can rotate around the axis of the first turntable under the driving of the driving device. The second centrifugal turntable 12 is driven by a driving device, and the second centrifugal turntable 12 can rotate around the axis of the second turntable under the driving of the driving device. The driving device can be a motor.
[0024] The liquid flowing out of the outlet of the first supply pipe 13 can drop onto the surface of the first centrifugal turntable 11, and the liquid flowing out of the outlet of the second supply pipe 15 can drop onto the surface of the second centrifugal turntable 12.
[0025] The humidification mechanism 1 adopts high-speed centrifugal turntable, and the liquid is passed through the fiber layer on the surface of the cloth 8 at a very high speed by the first centrifugal turntable 11 and the second centrifugal turntable 12, and is uniformly punched into the inside of the cloth 8. Since the liquid drops on the first centrifugal turntable 11 and the second centrifugal turntable 12 and is immediately thrown out by the centrifugal force, the first centrifugal turntable 11 and the second centrifugal turntable 12 can avoid accumulation of dirt and slurry, and avoid the problem of nozzle blockage, which has strong adaptability and low maintenance difficulty. It can improve the standard rate of the shrinkage rate of the cloth pre-shrinking machine and improve the stability of the cloth pre-shrinking machine.
[0026] Further, the first centrifugal turntable 11 is a plurality of first centrifugal turntables 11 arranged in a second direction; the second centrifugal turntable 12 is a plurality of second centrifugal turntables 12 arranged in a second direction; the first direction is perpendicular to the second direction.
[0027] A plurality of first centrifugal turntables 11 are arranged in a second direction in sequence, forming a row of first centrifugal turntables 11. A plurality of second centrifugal turntables 12 are arranged in a second direction in sequence, forming a row of second centrifugal turntables 12.
[0028] As shown in Figure 1 the first direction is shown along Figure 1 the left and right directions, and the second direction is shown along Figure 1The middle front-rear direction is shown.
[0029] The first centrifugal rotating disc 11 and the second centrifugal rotating disc 12 can humidify different positions of the cloth 8, so that each position of the cloth 8 is fully humidified.
[0030] Further, the first supply pipe 13 and the second supply pipe 15 are respectively provided with a metering valve.
[0031] The first supply pipe 13 and the second supply pipe 15 are respectively connected with the liquid supply device 14, the liquid supply of the first supply pipe 13 and the second supply pipe 15 is controlled through the metering valve, and the water content of the cloth 8 can be accurately controlled.
[0032] Further, the first supply pipe 13 can supply water, slurry and / or softener; and the second supply pipe 15 can supply water, slurry and / or softener.
[0033] The first supply pipe 13 can supply water, slurry and / or softener; and the second supply pipe 15 can supply water, slurry and / or softener.
[0034] The first supply pipe 13 and the second supply pipe 15 can supply water, slurry and softener, the first centrifugal rotating disc 11 and the second centrifugal rotating disc 12 can spin water, slurry and softener to the cloth 8, the slurry spraying process and the softener process can be simultaneously performed with the pre-shrinking process, so that the slurry spraying process, the softener process and the pre-shrinking process are integrated, compared with the traditional slurry washing which can only be performed in the garment stage, the work load and the energy consumption can be reduced, the defective products in the garment stage can be reduced, and the manufacturing cost can be reduced.
[0035] Further, the cloth pre-shrinking machine further comprises a pre-shrinking drying mechanism 2; the humidifying mechanism 1 and the pre-shrinking drying mechanism 2 are sequentially arranged along the conveying direction of the cloth 8; the pre-shrinking drying mechanism 2 comprises a roller assembly 21 and a transmission shaft 212; the roller assembly 21 comprises a plurality of rollers 211, and the plurality of rollers 211 are sequentially arranged along the conveying direction of the cloth 8; each roller 211 is drivingly connected with the transmission shaft 212 through a bevel gear.
[0036] The cloth enters the pre-shrinking drying mechanism 2 after being humidified by the humidifying mechanism 1.
[0037] The transmission shaft 212 is connected with a driving device, and the driving device drives the transmission shaft 212 to rotate around the axial direction of the transmission shaft 212. The driving device can be a motor. The axial direction of the driving shaft is parallel to the conveying direction of the cloth. The axial direction of each roller 211 is perpendicular to the conveying direction of the cloth.
[0038] The plurality of rollers 211 are arranged at intervals along the conveying direction of the cloth 8, and each roller 211 is provided with a first bevel gear 213 at one end thereof. A second bevel gear 214 is arranged on the transmission shaft 212, and the first bevel gear 213 is engaged with the second bevel gear 214, so that each roller 211 is in driving connection with the transmission shaft 212 through the bevel gears, and each roller 211 can rotate about its own axis.
[0039] The plurality of second bevel gears 214 are arranged at intervals along the axial direction of the transmission shaft 212, and the plurality of second bevel gears 214 are in one-to-one correspondence with the first bevel gears 213 on the plurality of rollers 211.
[0040] By changing the axial length of the transmission shaft 212, the length of the roller assembly 21 along the conveying direction of the cloth 8 can be changed. In the embodiment, the length of the roller assembly 21 along the conveying direction of the cloth 8 can reach 6 meters.
[0041] Each roller 211 is in driving connection with the transmission shaft 212 through the bevel gears to realize right-angle transmission. In this transmission mode, power transmission is relatively timely, so the speed between the front and rear rollers 211 along the conveying direction of the cloth 8 can be synchronized, avoiding the generation of pulling force when the cloth 8 is conveyed on the rollers 211, and allowing the cloth 8 to shrink more freely.
[0042] In the embodiment, the outer surface of the roller 211 is smooth, and therefore the speed between the front and rear rollers 211 along the conveying direction of the cloth 8 can be synchronized. The cloth 8 is in linear contact with the roller 211, which can reduce the friction area, thereby allowing the cloth 8 to better overcome the friction force to achieve the effect of free shrinkage, and maximize the guarantee of shrinkage rate and uniformity.
[0043] Further, the roller assembly 21 is multi-layered; the multi-layered roller assembly 21 is arranged at intervals along the vertical direction, and the rotating directions of the rollers 211 of adjacent roller assemblies 21 are opposite.
[0044] The roller assembly 21 is multi-layered, and the plurality of rollers 211 are arranged at intervals along the vertical direction, and the distance between adjacent layers of roller assemblies 21 is set according to specific conditions.
[0045] The rotating directions of the rollers 211 of adjacent layers of roller assemblies 21 are opposite, for example, from top to bottom, the rotating direction of the rollers 211 of the first layer is opposite to the rotating direction of the rollers 211 of the second layer, and the rotating direction of the rollers 211 of the second layer is opposite to the rotating direction of the rollers 211 of the third layer.
[0046] If the traditional machine wants to improve the speed, it must increase the length of the drying mechanism. This not only makes the machine more bulky, but also occupies more space, generates more heat loss, increases energy consumption, and has poorer economic benefits. In the embodiment, the rotation directions of the rollers 211 of the adjacent roller assemblies 21 are opposite, so that the cloth 8 is transported from the upper layer to the lower layer, the drying tunnel is longer, and the volume of the shrink drying mechanism 2 is smaller, which is more energy-saving.
[0047] Preferably, the feeding position and the discharging position of the shrink drying mechanism 2 are on the same side of the shrink drying mechanism 2, and the number of layers of the roller assembly 21 is an even number, so that the feeding position and the discharging position are on the same side of the shrink drying mechanism 2.
[0048] The cloth 8 enters the shrink drying mechanism 2 from one side of the first layer of roller assemblies 21, and the cloth 8 is transported from the upper layer to the lower layer until the last layer of cloth 8 is output from one side of the last layer of roller assemblies 21. Thus, the feeding and discharging positions are on the same side of the shrink drying mechanism 2, and workers do not need to walk back and forth on both sides of the shrink drying mechanism 2, thereby reducing the labor workload and improving the work efficiency.
[0049] The above structure makes the drying tunnel longer, smaller in volume, and more energy-saving. Compared with the traditional machine, the speed of the cloth shrinking machine provided by the embodiment reaches more than 3 times that of the traditional machine under the premise of the same volume and equivalent energy consumption, and the shrinkage rate is better and more stable. The length of the traditional machine is more than 10 meters, and the occupied area is large. The multi-layer back-and-forth transportation mode can greatly reduce the occupied area of the machine, place flexibly, and reduce the use cost of customers. The length of the traditional machine is more than 10 meters, and the cloth shrinking machine provided by the embodiment can realize the output of 3 traditional machines within a length of 5 meters.
[0050] Further, the distance between the adjacent rollers 211 is less than or equal to 0.5 mm along the conveying direction of the cloth 8.
[0051] The distance between the adjacent rollers 211 is less than or equal to 0.5 mm, so that the distance between the rollers 211 is close.
[0052] Further, a graphene heating plate is arranged above the roller assembly 21.
[0053] The heating and drying do not use large-area graphene infrared heating plates, and do not need high-pressure steam boilers. The graphene heating plate is arranged above the roller assembly 21 and directly above the cloth 8. Since the conveying mode is back-and-forth, one graphene heating plate can radiate the opposite side of the cloth 8 on the roller assembly 21 above it and the front side of the cloth 8 on the roller assembly 21 below it, so that the front and back sides of the cloth 8 are heated uniformly, greatly increasing the drying speed and the uniformity of the shrinkage.
[0054] The graphene heating plate is arranged above each layer of the roller assembly 21.
[0055] Due to the graphene infrared heating plate and the compact structure of the multi-layer roller assembly 21, the space occupation is small, the temperature rises quickly, and the heat loss is small. The power consumption is only one third of that of the traditional machine for the same output.
[0056] Further, the cloth pre-shrinking machine further comprises a cloth feeding roller mechanism; the cloth feeding roller mechanism, the humidifying mechanism 1 and the pre-shrinking drying mechanism 2 are sequentially arranged along the conveying direction of the cloth 8.
[0057] The cloth feeding roller mechanism comprises two feeding rollers 3 and two conveying rollers 4.
[0058] The two feeding rollers 3 are arranged in parallel and are connected with the driving device, which can drive the feeding rollers 3 to rotate around the axis of the feeding rollers 3. The cloth 7 is placed on the two feeding rollers 3. The rotating directions of the two feeding rollers 3 are opposite.
[0059] The two conveying rollers 4 are arranged in parallel and are connected with the driving device, which can drive the conveying rollers 4 to rotate around the axis of the conveying rollers 4. The rotating directions of the two conveying rollers 4 are opposite. The cloth 8 discharged from the cloth 7 is stretched into the two conveying rollers 4 and is conveyed to the humidifying mechanism 1 by the two conveying rollers 4.
[0060] One or two conveying rollers 4 can be arranged between the humidifying mechanism 1 and the roller conveying mechanism to convey the humidified cloth 8 to the pre-shrinking drying mechanism 2.
[0061] Further, the cloth pre-shrinking machine further comprises a cooling and shaping mechanism 5 and a folding and arranging mechanism 6; the cloth feeding roller mechanism, the humidifying mechanism 1, the pre-shrinking drying mechanism 2, the cooling and shaping mechanism 5 and the folding and arranging mechanism 6 are sequentially arranged along the conveying direction of the cloth 8.
[0062] The cloth 7 is placed on the two feeding rollers 3, is conveyed by the conveying rollers 4, is then subjected to two-side humidification by the humidifying mechanism 1, is conveyed to the pre-shrinking drying mechanism 2 after being humidified, is cooled and shaped by the cooling and shaping mechanism 5 when passing through the outlet slope, and finally falls on the folding and arranging mechanism 6.
[0063] The cloth pre-shrinking machine of the embodiment is made of aluminum alloy material, is resistant to high temperature, is not abraded, is not deviated, is not stained, and is low in maintenance difficulty. The cloth pre-shrinking machine is high in shrinkage rate and stability, is small in floor area, is low in maintenance, is high in efficiency, is low in energy consumption, and is various in functions.
