Description

Technical Field

[0001] The invention belongs to the technical field of knitted sweater production, in particular to a knitted sweater production device and a manufacturing process thereof. Background Art

[0002] Knitted sweaters are mostly made of wool, and their main features are strong extensibility and good elasticity, so they are comfortable to wear and have excellent wearing performance. When producing knitted sweaters, after the wool yarn raw materials enter the factory and are stored, the yarn count needs to be inspected for items such as the calibrated linear density and yarn uniformity. Only when they meet the requirements can they be put into production and use; after the wool yarn is tested and qualified, the hank yarn is first wound into a tube form by a yarn winding machine, and then the tube form of the wool yarn is knitted into semi-finished garment pieces by a knitting machine. After the knitted garment pieces are inspected and qualified, they are mechanically or manually sewn; the sewn knitted sweaters are shrinked by a shrinking machine, and the semi-finished knitted sweaters after shrinking are ironed and shaped by a steaming machine. The ironed knitted sweaters finally pass the manual garment inspection, and the knitted sweaters that pass the inspection become the final products.

[0003] Among them, the shrinking treatment of knitted sweaters is an important step in the feel and appearance of the final product. The shrinking treatment uses the shrinking characteristics of wool fibers to make the fibers expand and soften after being soaked in moisture and heat. Under the action of friction, they show advantages such as short nap, plump feel, and improved appearance. Small-scale knitted sweater manufacturers usually use shrinking machines to shrink knitted sweaters, and ordinary shrinking machines require resources such as steam, water and shrinking agents during their operation. These resources are also important factors affecting the shrinking effect of knitted sweaters.

[0004] When ordinary milling machines use tap water for milling, the tap water from the water plant is usually coagulated, precipitated, filtered, sent to the clean water tank and disinfected, and then input into the tap water pipe by the water pump at high pressure; since the carbonate and sulfate of Ca and magnesium ions contained in the water are not separated and removed, the hardness of the tap water is still very high and is hard water; and when it is necessary to mill the dyed knitted sweaters, the tap water itself contains more metal ions such as calcium and magnesium, and the metal ions attached to the knitted sweaters in the dyes make the wool in the knitted sweaters absorb a large amount of metal ions when the dyed knitted sweaters are milled with tap water, causing the wool in the knitted sweaters to harden, thereby reducing the effect of the knitted sweaters to have short pile under the action of friction, thereby affecting the milling performance of the knitted sweaters, and making the feel and appearance of the knitted sweaters after milling worse.

[0005] In view of this, the present invention proposes a knitted sweater production equipment and a manufacturing process thereof, which solves the problem that when using tap water to shrink the dyed knitted sweater, the metal ion content in the tap water is relatively high, causing the wool in the knitted sweater to absorb a large amount of metal ions, making the wool in the knitted sweater hard, thereby affecting the knitted sweater The effect of short pile under the action of friction is reduced, and further affecting the shrinkage performance of the knitted sweater, causing the feel and appearance of the knitted sweater after shrinkage to deteriorate. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that when a dyed knitted sweater is milled with tap water, the metal ion content in the tap water is relatively high, causing the wool in the knitted sweater to absorb a large amount of metal ions, making the wool in the knitted sweater hard, thereby reducing the effect of the knitted sweater to play the role of short pile under the action of friction, further affecting the milling performance of the knitted sweater, and making the feel and appearance of the knitted sweater after milling worse, the present invention proposes a knitted sweater production equipment and a manufacturing process thereof.

[0051] The knitted sweater production equipment of the present invention comprises a detection module, a knitting module, a sewing and patching module, a shrinking module, an ironing and shaping module, and a garment inspection module. The shrinking module performs shrinking treatment on the knitted sweater through a shrinking machine, and the shrinking machine comprises:

[0055] The motor 14 is installed between the surface of one side of the liquid storage tank 11 and the inner wall of the housing 1. The output end of the motor 14 is fixedly connected to one end of the shrinking cylinder 13, so that the motor 14 drives the shrinking cylinder 13 to rotate in the liquid storage tank 11;

[0056] The water softening mechanism 2 is installed in the housing 1 and is located above the liquid storage tank 11;

[0057] A No. 1 rod 15, the No. 1 rod 15 is evenly installed at the bottom of the water softening mechanism 2, the No. 1 rod 15 is connected to the surface of the water softening mechanism 2 through a return spring, one end of the No. 1 rod 15 is located in the water softening mechanism 2, and the other end is close to the rotating shaft 12;

[0058] The first block 16 is evenly fixed to the outer ring surface of the shrinking cylinder 13 close to the inner wall of the shell 1. One end of the first rod 15 contacts the surface of the first block 16. The movement of the first block 16 drives the first rod 15 to move linearly, thereby driving the water softening mechanism 2 to move.

[0059] A heating and temperature control component 17, which is installed in the liquid storage tank 11, and adjusts the temperature of the liquid in the liquid storage tank 11 by the heating and temperature control component 17;

[0060] The nozzle assembly 18 is installed in the liquid storage tank 11 near the top, and the nozzle assembly 18 is connected to the water softening mechanism 2 through a water pipe.

[0061] When producing knitted sweaters, after the wool yarn raw materials enter the factory and are stored, the testing and analysis department will promptly extract samples, and use the detection module to inspect the calibrated linear density, yarn uniformity and other items of the yarn count. Only when they meet the requirements can they be put into production and use. After the wool yarn passes the inspection, it enters the knitting module. First, the hank yarn is wound into a tube form by a yarn winding machine to make it a package suitable for knitting on a knitting machine; then the tube-form wool yarn is knitted into semi-finished garment pieces by a knitting machine, and the knitted semi-finished garment pieces finally enter the sewing and patching module after passing the inspection; the workshop sews the semi-finished garment pieces mechanically or manually according to the process requirements; the stitched semi-finished knitted sweater is shrunk by a shrinking machine to make the surface of the semi-finished knitted sweater have short nap and improve the appearance; the semi-finished knitted sweater after shrinking is ironed and shaped by a steaming machine, and the knitted sweater after ironing finally passes the manual garment inspection, and the knitted sweater that passes the inspection becomes the final product;

[0062] like Figures 1 to 5 As shown;

[0063] During use, after the knitted sweater is dyed, when the semi-finished knitted sweater after stitching is subjected to the shrinking treatment, a clothing door and a water outlet are provided on the shell 1 in the present application. The staff first opens the clothing door on the shell 1, puts the knitted sweater into the shrinking cylinder 13 and closes the clothing door, starts the shrinking machine and injects water into the water softening mechanism 2 through the water pump, the motor 14 drives the shrinking cylinder 13 to rotate, the shrinking cylinder 13 rotates with the support of the liquid storage tank 11 and the rotating shaft 12, the shrinking cylinder 13 drives the No. 1 block 16 and the sweater in the cylinder to rotate, the No. 1 block 16 contacts and squeezes the No. 1 rod 15, and the No. 1 rod 15 moves toward the direction close to the water softening mechanism 2 after being squeezed, The first rod 15 drives the components in the water softening mechanism 2 to move, and softens the water in the water softening mechanism 2, so that hard water is converted into soft water. Most of the water sources of factories come from water plants. The tap water contains more soluble calcium, magnesium and compounds, so the hardness is relatively large. After the tap water is softened, the metal ion content is reduced, and the amount of metal ions absorbed by the animal fiber in the sweater in the soft water is reduced, so that the hardness of the sweater after absorbing soft water is lower than that of the sweater after absorbing hard water, thereby improving the shrinking effect of the knitted sweater after dyeing, and then improving the finished appearance and feel of the knitted sweater, avoiding the reduction of the shrinking effect of the dyed sweater directly using tap water;

[0064] The water softening mechanism 2 discharges the soft water into the nozzle assembly 18 through the water pipe, and the nozzle assembly 18 sprays the soft water onto the sweater until the water stored in the liquid storage tank 11 contacts the sweater in the shrinking cylinder 13. After the sweater is fully moistened, the staff controls the water softening mechanism 2 to stop injecting water. The staff sets the temperature of the heating and temperature control assembly 17 so that the heating and temperature control assembly 17 heats the water in the liquid storage tank 11 to the shrinking temperature required for each batch of shrinking sweaters. After the sweater is fully moistened, the staff controls the water in the liquid storage tank 11 to be discharged from the water outlet through the controller in the shell 1, injects water into the liquid storage tank 11 again, and opens the clothing door at a fixed time and quantity to add shrinking agent into the liquid storage tank 11 to shrink the sweater. After the shrinking treatment of the sweater, the staff controls the motor 14 through the controller in the shell 1 to drive the shrinking cylinder 13 to rotate quickly to dehydrate the sweater in the cylinder. After the dehydration of the sweater is completed, it is taken out from the clothing door for subsequent treatment.

[0065] As an embodiment of the present invention, the water softening mechanism 2 includes:

[0066] The first box 21 is fixedly connected to the upper position of the liquid storage tank 11 in the housing 1, and the first rod 15 close to the rotating shaft 12 is connected to the first box 21 through a return spring;

[0067] The ion exchange resin membrane assembly 22 is fixedly connected to the No. 1 box 21 near the top, the top of the No. 1 box 21 is evenly fixedly connected with a water inlet pipe 23, and one side of the No. 1 box 21 is evenly fixedly connected with a group of water outlet pipes 24 below the horizontal position of the ion exchange resin membrane assembly 22;

[0068] The first plate 25 is slidably connected to the first box 21 near the bottom, and the bottom of the first plate 25 is fixedly connected to the first rod 15 near the rotating shaft 12.

[0069] like Figure 3 and Figure 6 As shown;

[0070] When in use, the shrinking cylinder 13 drives the No. 1 block 16 to rotate, the No. 1 block 16 contacts and squeezes the No. 1 rod 15, and the No. 1 rod 15 moves toward the No. 1 box 21 after being squeezed, and the No. 1 rod 15 drives the No. 1 plate 25 to move toward the ion exchange resin membrane assembly 22 in the No. 1 box 21. The contact part of the No. 1 rod 15 and the No. 1 box 21 is sealed by a sealing ring, and the edge of the No. 1 plate 25 and the inner wall surface of the No. 1 box 21 are sealed by a sealing strip. The No. 1 plate 25 squeezes the soft water in the No. 1 box 21, and the soft water is discharged through the outlet pipe 24 after being squeezed; when the No. 1 block 16 passes over the No. 1 rod 15, hard water is injected into the No. 1 box 21 through the water inlet pipe 23, and the No. 1 rod 15 is affected by the reset spring to move away from the No. 1 box 21 for reset, and the No. 1 rod 15 drives the No. 1 plate 25 to Move away from the ion exchange resin membrane assembly 22, so that the first box 21 is in a negative pressure state, forcing the hard water to pass through the ion exchange resin membrane assembly 22 from top to bottom. The ion exchange resin membrane assembly 22 softens the hard water located at the top of the ion exchange resin membrane assembly 22 in the first box 21 through the ion exchange technology. The softened hard water passes through the ion exchange resin membrane assembly 22 and becomes soft water, which is discharged from the outlet pipe 24 through the squeezing of the first plate 25. The metal ion content in the soft water is reduced. After the soft water is sprayed onto the sweater, the amount of metal ions absorbed by the animal fibers in the sweater in the soft water is reduced, so that the hardness of the sweater after absorbing soft water is reduced compared to the hardness of the sweater absorbing hard water, thereby improving the shrinkage effect of the knitted sweater after dyeing, and then improving the finished appearance and feel of the knitted sweater.

[0071] As an embodiment of the present invention, a partition plate 3 is fixedly connected between the horizontal position of the ion exchange resin membrane assembly 22 and the horizontal position of the water outlet pipe 24 in the first box 21, and a group of water filter holes 31 are evenly opened on the partition plate 3, and a plug 32 is slidably connected in the water filter hole 31, and the plug 32 is connected to the water filter hole 31 through a reset spring;

[0072] A frame 33 is fixedly connected to the top of the plug 32 , and the shape of the frame 33 matches the water filtering hole 31 .

[0073] like Figure 3 , Figure 7 and Figure 8 As shown;

[0074] When in use, through the cooperation between the partition 3, the water filter hole 31 and the plug 32, the plug 32 is a conventional corrosion-resistant rubber plug in the art. When the No. 1 plate 25 moves downward, a negative pressure is formed between the partition 3 and the No. 1 plate 25. The plug 32 is affected by the negative pressure between the partition 3 and the No. 1 plate 25 to open the water filter hole 31. At this time, the return spring on the plug 32 is stretched, and soft water flows from the water filter hole 31 into between the partition 3 and the No. 1 plate 25. When the No. 1 plate 25 moves upward, the No. 1 plate 25 squeezes the soft water. The plug 32 is reset by the reset spring to reclose the water filter hole 31, so that the soft water will not flow out through the water filter hole 31. The partition 3 and the No. 1 plate 25 squeeze each other, so that the soft water is discharged from the water outlet pipe 24, thereby isolating the soft water that passes through the ion exchange resin membrane component 22 and the hard water that does not pass through the ion exchange resin membrane component 22, and increasing the discharge amount of soft water in the No. 1 box 21, thereby increasing the amount of soft water sprayed by the nozzle assembly 18 onto the sweater, shortening the wetting time of the sweater, and further improving the shrinkage efficiency of the sweater.

[0075] As an embodiment of the present invention, a roller 34 is rotatably connected to the bottom of the No. 1 rod 15 .

[0076] like Fig. 9 As shown;

[0077] When in use, by setting the roller 34, when the No. 1 block 16 contacts and squeezes the bottom of the No. 1 rod 15, the No. 1 block 16 first contacts the roller 34, and the roller 34 rolls along the surface of the No. 1 block 16 and squeezes the No. 1 rod 15, so that the No. 1 rod 15 moves upward. When the No. 1 block 16 passes over the No. 1 rod 15, the roller 34 continues to roll along the surface of the No. 1 block 16, and the force applied to the No. 1 rod 15 by the reset spring on the No. 1 rod 15 causes the No. 1 rod 15 to move downward as it passes over the No. 1 block 16, thereby converting the sliding friction of the hard contact between the No. 1 rod 15 and the No. 1 block 16 into rolling friction, thereby reducing the frictional force between the No. 1 rod 15 and the No. 1 block 16, and preventing the No. 1 block 16 from rubbing against the No. 1 rod 15 for a long time and generating iron filings that fall into the shrinking cylinder 13 and damage the sweater.

[0078] As an embodiment of the present invention, the water softening mechanism 2 further includes:

[0079] The second box 4 is fixedly connected to one side of the first box 21, and the second box 4 is connected to the first box 21 through the outlet pipe 24, and the first rod 15 away from the rotating shaft 12 is connected to the second box 4 through a return spring;

[0080] A second plate 41, the second plate 41 is slidably connected in the second box 4, and the bottom of the second plate 41 is fixedly connected to the first rod 15 away from the rotating shaft 12;

[0081] The doser 42 is installed on the top of the No. 2 tank 4 and is connected to the No. 2 tank 4 through a solenoid valve;

[0082] The second block 43 is evenly fixed to the outer ring surface of the second box 4 corresponding to the shrinking cylinder 13.

[0083] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown;

[0084] When in use, when block 16 contacts and squeezes rod 15 close to rotating shaft 12, rod 15 far from rotating shaft 12 passes over block 23, rod 15 far from rotating shaft 12 is reset by reset spring, rod 15 in contact with box 4 is sealed by sealing ring, edge of plate 41 and inner wall surface of box 4 are sealed by sealing strip, rod 15 far from rotating shaft 12 drives plate 41 to move downward in box 4, so that box 4 is in negative pressure state when box 1 is drained, box 4 is in negative pressure water absorption state when box 1 is drained, thereby increasing the speed of soft water in box 1 21 flowing into box 2 4; when adding agent, controller in housing 1 controls doser 42 to inject shrinkage agent into box 2 4 through solenoid valve, so that soft water and agent are mixed in proportion and then discharged to nozzle assembly 18, thus optimizing the complexity of manual dosing work, thereby improving shrinkage processing efficiency of sweater;

[0085] When block No. 2 43 contacts and squeezes rod No. 1 15, rod No. 1 15 drives plate No. 2 41 to move, and there is a one-way valve in the water outlet pipe 24 connected between box No. 1 21 and box No. 2 4, so that plate No. 2 41 will not enter box No. 1 21 when squeezing the mixed medicine in box No. 2 4; plate No. 2 41 squeezes the medicine into the nozzle assembly 18, and the nozzle assembly 18 sprays the medicine onto the surface of the sweater and cooperates with the rotation of the shrinking cylinder 13 to shrink the sweater.

[0086] As an embodiment of the present invention, the second tank 4 is cylindrical, and the water inside the first tank 21 is tangentially passed into the second tank 4 through the outlet pipe 24;

[0087] The volume of the second box 4 is 2L, and the second box 4 is replaceable.

[0088] like Figure 2 , Figure 3 and Figure 5 As shown;

[0089] When in use, the second box 4 is set to be cylindrical, and the water in the first box 21 is tangentially passed into the second box 4 through the outlet pipe 24, so that after the first box 21 discharges the soft water into the second box 4, the soft water is affected by the annular inner wall of the second box 4 and flows along the inner wall of the second box 4, so that the soft water in the second box 4 is in a rotating state. When the agent is injected into the second box 4, the soft water in the moving state drives the agent to move, so that the soft water and the agent are fully mixed, and the uniformity of the mixing of the soft water and the agent during the shrinking treatment is improved, so as to avoid the phenomenon of uneven water-to-drug ratio at the first time after the agent is manually poured into the liquid storage tank 11, which affects the shrinking effect of the sweater;

[0090] By setting the volume of the No. 2 box 4 to 2L and making the No. 2 box 4 detachable and replaceable, when the staff controls the timing and quantity of adding chemicals to the liquid storage tank 11 through the dosing device 42, the water-to-drug ratio is changed according to the shrinkage requirements of the sweater based on a certain benchmark, thereby optimizing the complexity of manual dosing work and improving the shrinkage efficiency of the sweater. In the time interval when no chemicals are needed during the addition of chemicals, the controller in the shell 1 controls the solenoid valve of the dosing device 42 leading to the No. 2 box 4 to be closed, thereby blocking the flow of chemicals.

[0091] As an embodiment of the present invention, an electric push rod 44 is fixedly connected to the bottom of the No. 1 box 21 and the No. 2 box 4 near the No. 1 rod 15, so that when the output end of the electric push rod 44 is extended, it can clamp the bottom of the No. 1 rod 15 and restrict the No. 1 rod 15 from continuing to move.

[0092] like Figure 6 and Fig. 9 As shown;

[0093] When in use, by setting the electric push rod 44, when there is no need to inject water into the liquid storage tank 11, the staff controls the output end of the electric push rod 44 to extend through the controller in the shell 1, and when the No. 1 block 16 and the No. 2 block 43 respectively squeeze the No. 1 rod 15 close to the rotating shaft 12 and the No. 1 rod 15 away from the rotating shaft 12 to the output end passing through the electric push rod 44, the output end of the electric push rod 44 will clamp the bottom of the No. 1 rod 15 close to the rotating shaft 12 and the No. 1 rod 15 away from the rotating shaft 12, and limit the No. 1 rod 15 close to the rotating shaft 12 and the No. 1 rod 15 away from the rotating shaft 12 to continue to move under the influence of the reset spring, thereby achieving the purpose of closing the No. 1 box 21 and the No. 2 box 4, optimizing the complexity of the staff's operation, and thus improving the work efficiency of the sweater shrinkage process.

[0094] A process for making a knitted sweater, which is applicable to any of the above-mentioned knitted sweater production equipment, and comprises the following steps:

[0095] S1: When the wool yarn raw materials enter the factory and are stored, the testing and analysis department will promptly extract samples and use the testing equipment in the testing module to test the yarn count, linear density, yarn uniformity and other items. Only when they meet the requirements can they be put into production;

[0096] S2: After the wool yarn is tested and qualified, the hank yarn is firstly wound into a tube form by a yarn winder to make it a package suitable for knitting on a flat knitting machine; the tube-form wool yarn is then knitted into semi-finished garment pieces by a flat knitting machine, and the knitted semi-finished garment pieces are finally sent to the sewing and splicing module after passing the inspection, and the staff sews the semi-finished garment pieces mechanically or manually according to the process requirements;

[0097] S3: The semi-finished knitted sweater after stitching is subjected to a shrinking treatment by a shrinking machine, so that the surface of the semi-finished knitted sweater has short nap, thereby improving the appearance; the semi-finished knitted sweater after the shrinking treatment is ironed and shaped by a steaming machine, and the knitted sweater after ironing finally passes the manual garment inspection, and the knitted sweater that passes the inspection becomes the final product.

[0098] The specific workflow is as follows:

[0099] The staff first opens the clothing door on the housing 1, puts the knitted sweater into the shrinking cylinder 13 and closes the clothing door, starts the shrinking machine and injects water into the water softening mechanism 2 through the water pump, the motor 14 drives the shrinking cylinder 13 to rotate, the shrinking cylinder 13 drives the No. 1 block 16 to rotate, the No. 1 block 16 contacts and squeezes the No. 1 rod 15, and the No. 1 rod 15 moves toward the direction of the No. 1 box 21 after being squeezed, and the No. 1 rod 15 drives the No. 1 plate 25 to move toward the ion exchange resin membrane assembly 22 in the No. 1 box 21, and the No. 1 plate 25 squeezes the No. 1 box 21. The soft water is squeezed and discharged through the outlet pipe 24; when the No. 1 block 16 passes over the No. 1 rod 15, the hard water is injected into the No. 1 box 21 through the water inlet pipe 23, and the No. 1 rod 15 is affected by the reset spring to move away from the No. 1 box 21 to reset, and the No. 1 rod 15 drives the No. 1 plate 25 to move away from the ion exchange resin membrane assembly 22, so that the No. 1 box 21 is in a negative pressure state, forcing the hard water to pass through the ion exchange resin membrane assembly 22 from top to bottom. The ion exchange resin membrane assembly 22 uses ion exchange technology to The hard water at the top of the ion exchange resin membrane assembly 22 is softened, and the softened hard water passes through the ion exchange resin membrane assembly 22 to become soft water, and is discharged from the water outlet pipe 24 through the squeezing of the first plate 25; the water softening mechanism 2 discharges the soft water into the nozzle assembly 18 through the water pipe, and the nozzle assembly 18 sprays the soft water onto the sweater until the water stored in the liquid storage tank 11 contacts the sweater in the shrinking cylinder 13. After the sweater is fully moistened, the staff controls the water softening mechanism 2 to stop injecting water, and the staff sets the temperature of the heating and temperature control assembly 17 so that the heating and temperature control assembly 17 The water in the liquid storage tank 11 is heated to the shrinking temperature required for each batch of shrinking sweaters. After the sweaters are fully moistened, the staff controls the water in the liquid storage tank 11 to be discharged from the water outlet through the controller in the shell 1, and water is injected into the liquid storage tank 11 again, and the clothing storage door is opened at a regular and quantitative time to add shrinking agents into the liquid storage tank 11 to perform shrinking treatment on the sweaters. After the shrinking treatment of the sweaters, the staff controls the motor 14 through the controller in the shell 1 to drive the shrinking drum 13 to rotate rapidly to dehydrate the sweaters in the drum. After the sweaters are dehydrated, they are taken out from the clothing storage door for subsequent treatment.
