Description

Technical Field

[0001] This invention relates to the field of textiles, and more particularly to a setting device for cashmere knitted products. Background Technology

[0002] Cashmere knitted products, such as tops, cashmere sweaters, and scarves, are prone to wrinkles and deformation during production, processing, or use, which affects the appearance quality and lifespan of the cashmere knitted products. Traditional methods for setting cashmere knitwear mainly rely on manual surface treatment using ironing machines or steam ironing equipment. However, current setting methods have many problems. For example, traditional ironing requires manual operation on a piece-by-piece basis, necessitating the manual placement of frames or inserting setting boards inside the cashmere knitwear. This process is slow and cannot meet the needs of mass production. Furthermore, manual operation makes it difficult to ensure the uniformity of steam spray, easily leading to localized wrinkles and fiber damage. The drying process after ironing also lacks a scientific drying and cooling mechanism. Currently, natural hanging drying is more commonly used, which not only easily causes moisture from steam ironing to accumulate at the bottom of the cashmere knitwear, causing gravitational stretching, but also prevents the internal hydrogen bonds of the cashmere fibers from fully reorganizing. As a result, the setting effect weakens over time, leading to product shrinkage or re-wrinkling. When using current ironing methods, close contact and handling of cashmere knitwear by the hands can easily result in burns from high-temperature steam and hot irons.

[0003] Based on the above, it is necessary to develop a setting device for cashmere knitted products to solve the aforementioned problems. Summary of the Invention

Through the cooperation of a positioning mechanism, a pushing mechanism, a spreading mechanism, a steam injection mechanism, an output mechanism, a drying mechanism, and a detection mechanism, cashmere knitted products can undergo automated and safe steam shaping treatment. It can also perform timely and rapid drying and setting of cashmere knitted products after steam shaping treatment, achieving consistency in setting efficiency and quality, improving setting efficiency and quality, effectively eliminating wrinkles and preventing shrinkage, while avoiding manual contact with high-temperature components and ensuring operational safety.

[0006] As a further improvement of the present invention, the positioning mechanism includes an electric conveyor cylinder. An electric conveyor cylinder is installed on both the left and right sides of the upper side of the first support. A conveyor belt is installed between the electric conveyor cylinders. A guide plate is fixedly connected to the right rear side of the conveyor belt. Multiple sets of clamping plates are detachably and evenly arranged on the conveyor belt by fasteners. The number and size of the clamping plates are not unique.

[0007] As a further improvement of the present invention, the propulsion mechanism includes a first electric slide rail. The first electric slide rail is installed at the front and rear positions of the upper side of the moving part of the lifting electric slide rail. A propulsion frame is fixedly connected between the lower sides of the moving parts of the two first electric slide rails. Multiple second electric slide rails are detachably installed on the lower side of the propulsion frame. The number and size of the second electric slide rails are not unique. The expansion mechanism is detachably disposed on the lower side of the moving part of the second electric slide rail. The second electric slide rails are horizontally installed on the lower side of the propulsion frame in different orientations.

[0008] As a further improvement of the present invention, the expansion mechanism includes a displacement frame. The displacement frame is detachably connected to the lower side of the moving part of the second electric slide rail. The lower side of each displacement frame is fixedly connected to a mounting frame. The lower side of each mounting frame is fixedly connected to a rail. Each rail has a structure with two moving parts. The lower side of each moving part of each rail is fixedly connected to an expansion rod. The expansion rod is connected to the moving part of the rail. The length and number of the expansion rods are not unique. A first electric push rod is installed on both the front and rear sides of each rail. The first electric push rods at each rail are arranged in a horizontally opposed manner. The moving part of the first electric push rod at each rail is respectively connected to the upper side of the vertical rod of the expansion rod with the opposite position.

[0009] As a further improvement of the present invention, the steam injection mechanism includes a mechanical arm, which is installed at the upper front side of the second support. The mechanical arm is equipped with a steam injection pipe valve at its execution end. The steam injection pipe valve is used to connect to an external high-temperature saturated steam source and inject steam.

[0010] As a further improvement of the present invention, the output mechanism includes an electric output cylinder, and electric output cylinders are installed at both the front and rear positions on the upper side of the third bracket, and an output belt is installed between the electric output cylinders.

[0011] As a further improvement of the present invention, the drying mechanism includes a bearing seat. Bearing seats are fixedly connected to the rear positions on both sides of the third bracket. A rotating frame is rotatably connected between the two bearing seats. A drying cold air generating module is installed at the front right position of the rotating frame. The drying cold air generating module is connected to an external drying cold air generating source. An air outlet is installed on the front side of the rotating frame.

The detection mechanism includes a connecting rod, which is fixedly connected to the middle position of the third support. Multiple temperature and humidity sensors are installed on the upper side of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves rapid clamping, conveying and expansion of cashmere knitted products through the coordinated work of the positioning mechanism, the propulsion mechanism and the expansion mechanism. It eliminates the need for manual frame mounting or insertion of shaping plates, shortens the processing time of a single product, enables efficient and consistent shaping of large batches of cashmere knitted products, and reduces the intensity of manual operation and safety hazards.

[0014] 2. By employing a pre-programmable operation method for the steam injection mechanism and drying mechanism, along with various styles of detachable clamping plates and expansion frames, this invention enables the cashmere knitwear shaping device to adapt to the mass shaping needs of different styles and types of cashmere knitwear products, achieving continuous and batch cashmere knitwear product shaping work.

[0015] 3. This invention employs a steam jetting mechanism to rapidly penetrate cashmere fibers with high-temperature saturated steam, causing the hydrogen bonds in the fiber molecular chains to open and the internal stress to relax. This softens the cashmere knitted products, allowing wrinkles to be quickly eliminated under their own weight and slight external force. Furthermore, a drying mechanism rapidly cools the cashmere fibers with low-temperature drying air, causing the hydrogen bonds to recombine in a new, flat state and the molecular chains to freeze and fix. This enables the cashmere knitted products to maintain their shape and effectively prevents product shrinkage.

[0016] 4. By employing an expansion mechanism, this invention can expand and fix cashmere knitted products without human contact with them at high temperatures. It also eliminates the need for manual transfer of cashmere knitted products that have undergone high-temperature steam treatment, thus avoiding the risk of burns from direct human operation in a high-temperature steam environment. Furthermore, the addition of a robotic arm and steam injection valve enables remote control and automated operation, further ensuring the safety of operators. Attached Figure Description

Detailed Implementation

[0030] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] Example 1, as Figures 1-5As shown, a cashmere knitted product shaping device includes a first support 1, a lifting electric slide rail 2, a second support 3, a third support 4, a positioning mechanism 5, a pushing mechanism 6, a supporting mechanism 7, a steam injection mechanism 8, an output mechanism 9, and a drying mechanism 10. The first support 1 is a leg structure. The lifting electric slide rail 2 is installed at the front right side of the first support 1. The lifting electric slide rail 2 is a servo-controlled lift. The second support 3 is located at the rear right side of the first support 1. The second support 3 is a portal frame structure. The third support 4 is located in the hollow space inside the second support 3. The third support 4 is a leg structure. The first support 1, the second support 3, and the third support 4 are all used for installation on the workshop floor.The first support 1 is equipped with a positioning mechanism 5, which is used to clamp, position, and convey cashmere knitwear to the right, opening the bottom edge and cuffs of cashmere knitwear such as tops. The upper side of the moving part of the lifting electric slide rail 2 is equipped with a pushing mechanism 6, which drives the pushing mechanism 6 to move up and down. The pushing mechanism 6 is equipped with an expanding mechanism 7, which, in cooperation with the positioning mechanism 5, extends into the interior of the cashmere knitwear. This allows the expanding mechanism 7 to extend from the position where the bottom edge and cuffs of the cashmere knitwear, such as tops, are opened by the positioning mechanism 5. The expansion mechanism 7 is used to expand the cashmere knitwear inside, allowing it to unfold to the desired shaping and setting state, and to fix the edges of the cashmere knitwear to prevent curling. A steam injection mechanism 8 is located above the front of the second support 3. The steam injection mechanism 8 automatically injects saturated steam into the cashmere knitwear unfolded below, allowing the saturated steam to quickly penetrate the cashmere fibers. The steam injection mechanism 8 can also be manually operated to inject steam for extended periods into areas with more wrinkles on the surface of the cashmere knitwear, ensuring that the saturated steam is evenly sprayed onto the entire surface of the cashmere knitwear, filling the cashmere fibers. The fibers absorb heat and moisture, softening completely and effectively relaxing internal stress. Wrinkles are completely eliminated, making the fibers easier to stretch or change shape under external force. Then, a scraper can be used to gently smooth some of the wrinkles on the surface of the cashmere knitwear at the right side of the first support 1 to smooth out the wrinkles and restore smoothness. The steam jet mechanism 8 opens a large number of hydrogen bonds between cashmere fiber molecular chains, enhancing the mobility of macromolecular chains, reducing the rigidity and yield stress of the cashmere fibers, and putting them into a plastic state. This relaxes the internal stress of the cashmere knitwear, allowing the original wrinkles to... The edges of the cashmere knitwear can be easily smoothed out by its own weight and with the help of the expansion mechanism 7. This not only fixes the cashmere knitwear without requiring manual contact with the cashmere knitwear that has been exposed to high-temperature steam, thus avoiding burns and improving safety during the shaping process, but also prevents the edges of the cashmere knitwear from curling up during the shaping process. Compared with the traditional method of using an ironing machine to iron and shape the surface of cashmere knitwear, this method also reduces manual operation time and workload, and improves the processing speed and efficiency of cashmere knitwear.The third support 4 is equipped with an output mechanism 9. The pushing mechanism 6 can push the cashmere knitwear, after being shaped by the steam jet mechanism 8, to the output mechanism 9 without changing its flat state after shaping. The output mechanism 9 is used to continue transporting the shaped cashmere knitwear. The upper side of the third support 4 is equipped with a drying mechanism 10. The drying mechanism 10 is used to dry the cashmere knitwear after high-temperature steam shaping with low-temperature cold air for shaping. The drying mechanism 10 can spray low-temperature cold air onto the cashmere knitwear, so that the dry cold air can quickly remove the heat and moisture inside the cashmere knitwear after high-temperature steam shaping, causing the fiber temperature to drop sharply below its glass transition temperature. This causes the open hydrogen bonds inside the cashmere fibers to recombine in new and relaxed positions, the molecular chain segments are frozen and fixed, and new hydrogen bonds are formed. This allows the cashmere fibers to maintain a new shape in a relaxed and flat state, so that the flat and wrinkle-free state of the cashmere fibers can be permanently fixed, thereby achieving a long-lasting shaping effect and preventing the cashmere knitwear from shrinking.

[0032] like Figures 6-7As shown, the positioning mechanism 5 includes an electric conveyor cylinder 50, a conveyor belt 51, a guide plate 52, and a clamping plate assembly 53. Electric conveyor cylinders 50 are installed on both the left and right sides of the upper side of the first support 1. Each electric conveyor cylinder 50 is driven by a servo motor and controlled by a servo. A conveyor belt 51 is installed between the electric conveyor cylinders 50. The conveyor belt 51 has a smooth, flat structure and is used to flatten cashmere knitted products. Starting the electric conveyor cylinder 50 will cause the conveyor belt 51 to rotate, thus transporting the cashmere knitted products. A fixed section is located on the right rear side of the conveyor belt 51. A guide plate 52 is fixedly connected, and the upper side of the guide plate 52 has a smooth flat structure. The guide plate 52 is used for the transmission and conveying between the right side of the relay conveyor belt 51 and the output mechanism 9. Multiple sets of clamping plates 53 are detachably and evenly arranged on the conveyor belt 51 by fasteners. The number and size of the clamping plates 53 are not unique. For example, three clamping plates 53 can be used as a group to position a collection of cashmere knitted products. These three clamping plates 53 are used to position and open the bottom and two cuffs of cashmere knitted products such as a top. The clamping plates 53 have a low-clamping elasticity double-layer clamping structure. The elastic clip assembly 53 is designed for easy opening and closing. The interconnection of the double-layer clamping mechanism of the clip assembly 53 is a grooved arc-shaped structure. The expansion mechanism 7 can extend into the interior of the cashmere knitted product through the grooved structure of the arc-shaped structure of the clip assembly 53. The clip assembly 53 can be opened from the left side of the first bracket 1, and the bottom and lower layer of the cashmere knitted product are placed between the double-layer clamping structure of the clip assembly 53, so that the bottom and lower layer of the cuff are completely inserted into the arc-shaped structure of the clip assembly 53, and the upper layer of the bottom and upper layer of the cuff are located on the upper side of the arc-shaped structure of the clip assembly 53. The cashmere knitwear is placed in such a way that the bottom and cuffs are partially open. Depending on the style and type of cashmere knitwear to be shaped, different numbers and positions of clamping plates 53 can be installed on the conveyor belt 51 according to its structure and the required open position. This allows the cashmere knitwear to be quickly and accurately positioned on the conveyor belt 51, so that the expansion mechanism 7 can quickly extend and expand it. This method allows for flexible and adaptive adjustments to be made according to different styles and types of cashmere knitwear, thereby improving the applicability of the cashmere knitwear shaping device.

[0033] like Figures 8-9As shown, the propulsion mechanism 6 includes a first electric slide rail 61, a propulsion frame 62, and a second electric slide rail 63. The first electric slide rail 61 is installed at both the front and rear positions on the upper side of the moving part of the lifting electric slide rail 2. The first electric slide rail 61 consists of servo-controlled rails 73 arranged horizontally. The propulsion frame 62 is fixedly connected between the lower sides of the moving parts of the two first electric slide rails 61. The first electric slide rail 61 can drive the propulsion frame 62 to move back and forth. Multiple second electric slide rails 63 are detachably installed on the lower side of the propulsion frame 62. The number and size of the second electric slide rails 63 are not unique. The expansion mechanism 7 is detachably divided into... Located below the moving part of the second electric slide rail 63, the second electric slide rail 63 is horizontally installed on the lower side of the push frame 62 with different orientations, so that the moving part of the second electric slide rail 63 can be installed with the orientation corresponding to the oblique direction of the cuff of the top when the cuff of the top is obliquely positioned relative to the cashmere knitted product positioned on the conveyor belt 51. This allows the moving part of the second electric slide rail 63 to drive the expansion mechanism 7 provided below its moving part to move obliquely and extend into the cuff of the top through the clamping plate group 53 to expand the cuff of the top.

[0034] like Figures 9-11As shown, the expansion mechanism 7 includes a displacement frame 71, a mounting frame 72, a track 73, an expansion rod 74, and a first electric push rod 75. The displacement frame 71 is detachably connected to the lower side of the moving parts of the second electric slide rail 63. The mounting frame 72 is fixedly connected to the lower side of each displacement frame 71. Each mounting frame 72 is an inverted door frame structure. A track 73 is fixedly connected to the lower side of each mounting frame 72. Each track 73 has two moving parts. An expansion rod 74 is fixedly connected to the lower side of each moving part of each track 73. The expansion rod 74 is an L-shaped thin rod. The vertical rod structure of the expansion rod 74 is connected to the moving parts of the track 73. The horizontal parts of the expansion rod 74 have smooth surfaces and ball ends. The smooth surfaces and ball ends of the expansion rod 74 are used to prevent damage when it extends into the cashmere knitted product. In the case of snagging, the length and number of the expansion rods 74 are not unique, so as to be suitable for different styles and types of cashmere knitted products. Each track 73 has a first electric push rod 75 installed on both the front and rear sides. The first electric push rods 75 at each track 73 are arranged in a horizontally opposed layout. The moving parts of the first electric push rods 75 at each track 73 are respectively connected to the upper side of the vertical rod of the expansion rod 74 in the opposite position, so that the two first electric push rods 75 at each set of mounting frames 72 can drive the expansion rods 74 connected to them to move closer and further away from each other through the moving parts of the track 73. The second electric slide rail 63 can drive the two contact rods in the contact state through the displacement frame 71 and the mounting frame 72 to extend into the interior of the cashmere knitted product through the arc-shaped groove structure of the clamping plate group 53.When the positioning mechanism 5 transports a cashmere knitted product, such as a top, below the propulsion mechanism 6, and the multiple clamping groups 53 positioning the top are respectively located below each expansion rod 74, the lifting electric slide rail 2 can be controlled to drive the propulsion mechanism 6 downward, so that each expansion rod 74 moves downward until it is on the same horizontal line as the arc-shaped groove structure of the corresponding clamping group 53. At this time, the multiple second electric slide rails 63 can be controlled to drive the expansion rods 74 to move, so that each expansion rod 74 extends into the arc-shaped groove structure of the corresponding clamping group 53, and the expansion rod 74 passes through the opening of the top opened by the clamping group 53. The expansion rod 74 extends into the garment until it completely passes through the arc-shaped structure of the clip assembly 53. Then, multiple first electric push rods 75 can be controlled to operate, causing each push rod 75 to drive its connected expansion rod 74 in opposite directions. This ensures that the expansion rod 74 at each set of tracks 73 moves in opposite directions to contact the cuffs or bottom edges of the garment, expanding it and fixing its overall shape and edges. Afterward, the first electric slide rail 61 can be controlled to move the push frame 62 rearward, causing the multiple expansion frames to lift the garment out of the clip assembly 53. The garment is released from the clamping and contact of the clip assembly 53, and then the lifting electric slide rail 2 is finely adjusted so that the garment, supported by multiple expansion rods 74, is completely laid flat on the upper side of the conveyor belt 51. Except for the expansion rods 74 used for overall shape fixation and edge fixation, the garment can be in a flat state without a frame or shaping plate, saving the time of manually attaching the frame and inserting the shaping plate. The expansion amount driven by the first electric push rod 75 to expand the expansion rods 74 can be set according to the bottom edge and two cuffs of the cashmere knitted product to be shaped. When the first electric push rod 75 drives the expansion rods 74 to expand, it can avoid cashmere knitted products from being shaped. If the garment is excessively stretched or insufficiently expanded, it can then undergo high-temperature steam shaping treatment via the steam jet mechanism 8. After the steam shaping treatment is completed, the lifting electric slide rail 2 can be controlled to move the expansion rod 74 and the garment it supports upwards until they are no longer in contact with the conveyor belt 51. The first electric slide rail 61 can then be controlled to move the entire push frame 62 backwards, causing the garment supported by the expansion rod 74 to move backwards to the output mechanism 9. Afterwards, the first electric slide rail 61, the second electric slide rail 63, and the lifting electric slide rail 2 can be reset to allow for the same treatment of the next cashmere knitted product.

[0035] like Figure 4As shown, the steam injection mechanism 8 includes a robotic arm 81 and a steam injection valve 82. The robotic arm 81 is installed at the upper front position of the second support 3. The robotic arm 81 is a six-axis robotic arm system controlled by a servo system. The execution end of the robotic arm 81 is equipped with the steam injection valve 82, which is used to connect to an external high-temperature saturated steam source and inject steam. The movement process of the robotic arm 81 can be designed according to each batch of cashmere knitted products with consistent style and size, and the output status of the steam injection valve 82 and the external steam source can be automatically controlled simultaneously. After the robotic arm 81 and the steam injection valve 82 are opened, they can automatically perform steam shaping on the batch of cashmere knitted products. Manual operation can also be performed on the right side of the first support 1. The robotic arm 81 and steam injection valve 82 are individually controlled at a specific location on a cashmere knitted product to perform extended steam injection in an area with more wrinkles, while a hand scraper is used to gently smooth the wrinkles. The steam injection mechanism 8 reduces the rigidity and yield stress of the cashmere fibers, bringing them into a plastic state. This relaxes the internal stress of the cashmere knitted product, and the existing wrinkles can be easily eliminated by its own weight and gentle smoothing with tools. Alternatively, while the steam injection valve 82 is steaming the cashmere knitted product, the first electric push rod 75 can be controlled to drive the expansion rod 74 to retract inward, allowing the steam injection valve 82 to steam inject the edges of the cashmere knitted product.

[0036] like Figures 4-5 As shown, the output mechanism 9 includes an electric output cylinder 91 and an output belt 92. Electric output cylinders 91 are installed at both the front and rear positions on the upper side of the third bracket 4. Each electric output cylinder 91 is a transmission cylinder driven by a servo motor and controlled by a servo. An output belt 92 is installed between the electric output cylinders 91, and the output belt 92 has a smooth structure with dense perforations. Through the cooperation of the pushing mechanism 6 and the expanding mechanism 7, the first electric slide rail 61 is controlled to move the pushing frame 62 backward, causing the top supported by the expanding rod 74 to move backward above the output belt 92. Subsequently, the lifting electric slide rail 2 can be controlled to move the expanding frame downward. The mechanism moves the cashmere knitted product, which is being expanded at the expansion frame, downwards to a position on the upper side of the output belt 92. Then, it controls the two opposing expansion frames to retract and move forward to reset the second electric slide rail 63, causing the expansion frame to detach from the cashmere knitted product and place the cashmere knitted product flat on the upper side of the output belt 92. Then, it controls the push mechanism 6 and the lifting electric slide rail 2 to move forward to reset. At this time, it controls the output belt 92 to run until the cashmere knitted product on the output belt 92 continues to move backwards to a position below the drying mechanism 10 for drying.

[0037] like Figures 4-5As shown, the drying mechanism 10 includes a bearing 101, a rotating frame 102, a drying cold air generating module 103, an air outlet 104, and a second electric push rod 105. Bearings 101 are fixedly connected to the rear positions of both sides of the third bracket 4. The rotating frame 102 is rotatably connected between the two bearings 101. The drying cold air generating module 103 is installed at the front right side of the rotating frame 102 and is connected to an external drying cold air source. An air outlet 104 is installed on the front side of the rotating frame 102. The air inlet of the air outlet 104 is connected to the output of the drying cold air generator module. The drying cold air generator module receives drying cold air from the external drying cold air source and outputs it to the air outlet 105. Inside the third bracket 4, the exhaust 104 is used to diffuse the incoming dry, cold air downwards. Second electric push rods 105 are rotatably mounted at the center of both sides of the third bracket 4. These second electric push rods 105 are controlled by a servo system, and their extension / retraction components are rotatably connected to the left and right positions of the rotating frame 102. Activating the second electric push rod 105 causes its moving parts to extend or retract, thereby causing the rotating frame 102 to rotate via the bearing 101. This, in turn, causes the rotating frame 102 to rotate the dry, cold air generating module 103 and the exhaust 104 clockwise, until the exhaust 104 rotates until its bottom surface is aligned with the output belt 92. In a parallel configuration, the cashmere knitted products on the upper side of the output belt 92 are positioned directly below the air outlet 104. Then, the drying and cooling air generating module 103 is activated, inputting cold air into the air outlet 104. The air outlet 104 then outputs the dry, cold air downwards to the cashmere knitted products on the upper side of the output belt 92, which have undergone high-temperature saturated steam shaping. This allows the dry, cold air to quickly remove heat and moisture from the cashmere knitted products after high-temperature steam shaping. The dry, cold air blown into the cashmere knitted products passes through each fiber layer and exits downwards from the porous output belt 92, causing the fiber temperature to drop sharply below its glass transition temperature. This allows the hydrogen bonds within the cashmere fibers to open in new... The cashmere fibers recombine in their relaxed and stretched positions, freezing and fixing the molecular chain segments, and reforming new hydrogen bonds. This allows the cashmere fibers to maintain a new shape in a relaxed and flat state, permanently fixing the smoothness and wrinkle-free state of the cashmere fibers, thus achieving a lasting shaping effect and preventing the cashmere knitted products from shrinking. After the cashmere knitted product is shaped as described above, the second electric push rod 105 can be controlled to drive the rotating frame 102 to reset, thereby causing the drying cold air generating module 103 and the air outlet 104 to rotate counterclockwise to reset. Then, the output operation continues to be controlled, causing the output belt 92 to continue to transport the shaped cashmere knitted product on its upper side to the rear side, where it is then manually collected and sorted.

[0038] like Figure 12As shown, it also includes a detection mechanism 11, which includes a connecting rod 111 and a temperature and humidity sensor 112. The detection mechanism 11 is located in the middle of the third support 4, directly below the air outlet 104 after it has been rotated clockwise to be parallel to the output belt 92. The detection mechanism 11 is used to detect the moisture content and temperature of the dry cold air blown out of the air outlet 104 after it passes through the cashmere knitted product, so as to detect the state of the cashmere knitted product, which is at high temperature and high moisture after being treated by high temperature steam, when it is dried by dry cold air, so as to accurately control the drying time required for the cashmere knitted product. The connecting rod 111 is fixedly connected in the middle of the third support 4. Multiple temperature and humidity sensors 112 are installed on the upper side of the connecting rod 111. The temperature and humidity sensors 112 are used to detect the temperature and moisture content of the gas passing through it and output the temperature and moisture content data to the outside, so as to determine whether the moisture content and temperature in the cashmere knitted product dried by cold air meet the shaping standard.

[0039] Example 2, as Figures 1-12As shown, the working process of the cashmere knitwear shaping device is as follows: ① Connect the high-temperature saturated steam source of the steam injection mechanism 8 and the dry cold air source of the drying mechanism 10, and connect the power circuit and control circuit of the knitwear shaping device; ② According to the style and size of the cashmere knitwear to be processed, such as a top, pre-install the corresponding number and position of clamping plate groups 53 on the conveyor belt 51 of the positioning mechanism 5, such as three clamping plate groups 53 corresponding to the bottom edge and two cuffs of the top respectively; ③ The operator, positioned on the left side of the conveyor belt 51, inserts the lower layer of the cashmere knitwear, such as the bottom edge and cuffs of the top, between the double-layer clamping structure of the clamping plate group 53, so that the cuffs and bottom edge are partially open, and the upper layer is naturally laid flat on the arc-shaped structure of the clamping plate group 53. On the upper side; ④ Start the electric conveyor 50 to run intermittently, driving the conveyor belt 51 to intermittently transport the tops to the right, and as in the process described in "③" above, position multiple tops at multiple sets of clip groups 53 respectively; ⑤ When a top is transported to the right to a position directly below the propulsion mechanism 6, and the clip group 53 is aligned with the expansion rod 74 of the expansion mechanism 7; control the lifting electric slide rail 2 to drive the propulsion mechanism 6 to move down, so that each expansion rod 74 and the arc-shaped groove structure of the corresponding clip group 53 are on the same horizontal line, then start the second electric slide rail 63 to push the displacement frame 71 and the mounting frame 72, so that the expansion rod 74 extends into the inside of the top along the groove of the clip group 53 until the expansion frame completely passes through the clip. The first electric push rod 75 at each of the second electric tracks 73 is then controlled to move, causing the two oppositely positioned expansion rods 74 to move in opposite directions, opening the cuffs and bottom edges of the garment, making it fully unfolded to a flat state. Then, the first electric slide rail 61 is activated, driving the push frame 62 to move backward, so that the expansion rods 74, after being expanded and fixed to the garment, are released from the clamping of the clip group 53, and are lifted and laid flat on the conveyor belt 51. ⑥ The motion trajectory of the robotic arm 81 is preset, and the steam injection valve 82 is activated to evenly spray high-temperature saturated steam onto the cashmere knitted product below, allowing the steam to quickly penetrate the cashmere fibers, opening the hydrogen bonds of the molecular chains, softening the fibers into a plastic state, and making the inner... The stress in the area is relaxed, and the wrinkles initially unfold under their own weight. If there are stubborn wrinkles in a certain area, manual intervention can be used to control the robotic arm 81 to extend the steam spray time in a specific area and gently smooth the surface with a scraper to accelerate the elimination of wrinkles. ⑦ Control the lifting electric slide rail 2 to raise the expansion mechanism 7 so that the garment is removed from the conveyor belt 51. Start the first electric slide rail 61 to push the push frame 62 to move backward and transport the garment to the top of the output belt 92. Lower the expansion mechanism 7 so that the garment is placed flat on the top of the output belt 92. Then control the expansion rod 74 to retract and reset, detaching it from the inside of the cashmere knitted product. Start the electric output cylinder 91 to drive the output belt 92 to transport the garment backward until it is located directly below the drying mechanism 10.⑧ Activate the second electric push rod 105 to rotate the rotating frame 102 clockwise, aligning the bottom surface of the air outlet 104 with the output belt 92, and aiming it at the garment. Turn on the drying cold air generating module 103 to deliver low-temperature drying cold air to the air outlet 104, blowing it evenly onto the surface of the garment. The cold air penetrates the fiber layer, rapidly reducing temperature and humidity, causing the fiber hydrogen bonds to recombine in a new, flat state, freezing and fixing the molecular chains until the shaping is complete. Then, control the second electric push rod 105 to pull the rotating frame 102 counterclockwise to reset, restoring the drying mechanism 10 to its initial state. Afterward, control the output belt 92 to continue running, conveying the shaped garment to the end for manual collection and sorting.

[0040] In addition, for thick cashmere knitted products, after performing the above process once, the cashmere knitted product can be flipped over and fixed at positioning mechanism 5, and then the process can be repeated as described above to perform double-sided shaping and setting of the thick cashmere knitted product.

[0041] Through the coordination of positioning, propulsion, expansion, steam injection, output, drying, and detection mechanisms, cashmere knitted products can undergo automated and safe steam shaping treatment. Furthermore, the steam-shaped cashmere knitted products can be dried and set quickly and efficiently, achieving consistency in setting efficiency and quality. This improves setting efficiency and quality, effectively eliminates wrinkles and prevents shrinkage, while avoiding manual contact with high-temperature components, ensuring operational safety.
