Description

Technical Field

[0001] The utility model belongs to the technical field of fabric shaping, and particularly relates to a shaping device for fabric production. Background Art

[0002] There are various types of fabrics. However, from a macroscopic perspective, those high-quality and high-grade fabrics usually have several remarkable characteristics: comfortable to wear, sweat-absorbent and breathable, good drape and stiffness, visually noble, and soft to the touch. As one of the three major elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the expressiveness of clothing color and shape. During the production process, in order to improve the quality of fabrics, shaping treatment is usually required.

[0003] However, the current shaping devices have relatively complex structures, and the fabrics need to be continuously cross-wound inside the devices for shaping operations, which results in low operation efficiency and is prone to fabric damage. This not only increases the production cost but also reduces the production efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above-mentioned disadvantages of the prior art and provide a shaping device for fabric production.

[0005] The technical solution adopted to solve the above technical problem is: a shaping device for fabric production, including a first conveying rack, a smooth conveyor belt is rotatably connected inside the first conveying rack, two processing pads are arranged inside the smooth conveyor belt, the processing pads are fixedly connected with the first conveying rack, a first shaping mechanism and a second shaping mechanism are respectively installed on the top of the smooth conveyor belt, a fabric loosening mechanism is fixedly connected to one end of the first conveying rack, a second conveying rack is arranged at the end of the first conveying rack where the fabric loosening mechanism is installed, and a fabric placement basket is slidably connected to the end of the second conveying rack away from the first conveying rack.

[0006] Further, the two processing pads are respectively located at both ends of the first conveying rack, the top ends of the processing pads are slidably attached to the inner wall of the smooth conveyor belt, the two processing pads respectively correspond to the first shaping mechanism and the second shaping mechanism, hydraulic lifting columns are fixedly connected to the bottom ends on both sides of the processing pads, the telescopic ends of the hydraulic lifting columns penetrate and slide through the processing pads, and the telescopic ends of the hydraulic lifting columns are respectively fixedly connected to the first shaping mechanism and the second shaping mechanism.

[0007] Through the above technical solution, the processing pads are located inside the conveyor belt and correspond to the first shaping mechanism and the second shaping mechanism. When the first shaping mechanism and the second shaping mechanism descend through the hydraulic lifting columns to contact the smooth conveyor belt for work, they perform support and auxiliary work, thereby ensuring the fabric shaping effect.

[0008] Furthermore, the first shaping mechanism includes a first shaping frame, which is fixedly connected to the telescopic end of the hydraulic lifting column. A shaping roller is rotatably connected to the inner side of the first shaping frame, and the cylindrical surface of the shaping roller is in rotational contact with the smooth conveyor belt.

[0009] Through the above technical solution, when the fabric is conveyed by the smooth conveyor belt, the two shaping rollers in the middle of the first shaping frame continuously roll and extend the moving fabric, so as to achieve the shaping effect. The rotation direction of the shaping roller is consistent with the movement direction of the smooth conveyor belt, ensuring that the fabric will not be pulled or wrinkled unnecessarily during the shaping process.

[0010] Furthermore, the second shaping mechanism includes a second shaping frame, which is fixedly connected to the telescopic end of the hydraulic lifting column. A partition strip is fixedly connected to the middle of the second shaping frame. Fixed sliding rods are fixedly connected to both sides inside the second shaping frame. The middle of the fixed sliding rods is fixedly connected through both ends of the partition strip. A number of convex plates are arranged on both sides of the partition strip, and a shaping plate is fixedly connected to the bottom end of the convex plate.

[0011] Through the above technical solution, the second shaping mechanism can ensure the stability of the convex plates during the fabric shaping process through the structural design of the partition strip and the fixed sliding rods. At the same time, the shaping plates precisely shape the fabric, so that the fabric can be further finely shaped after the preliminary shaping by the first shaping mechanism, thus achieving a more perfect shaping effect.

[0012] Furthermore, both sides of the top end of the convex plate are respectively slidably connected through the fixed sliding rods. A second limiting sliding rod is arranged through between every two of the convex plates. One end of the second limiting sliding rod is fixedly connected through one of the convex plates, and the other end of the second limiting sliding rod is slidably connected through the other convex plate. The middle of the convex plate located outside the second shaping frame is slidably connected through a first limiting sliding rod. One end of the first limiting sliding rod away from the convex plate is fixedly connected to the second shaping frame. Two hydraulic push rods are fixedly connected to the top end of the second shaping frame, and the two hydraulic push rods are symmetrical to each other. The telescopic end of the hydraulic push rod is fixedly connected to a convex plate close to the partition strip.

[0013] Through the above technical solution, the sliding connection of the convex plates and the design of the limiting sliding rods ensure the precise position control of the convex plates during the fabric shaping process. By the telescopic action of the hydraulic push rods, an appropriate force can be applied to the convex plates. The setting of the second limit makes several convex plates contract successively, thus ensuring the uniformity and consistency of the fabric shaping.

[0014] Furthermore, the fabric loosening mechanism includes two fixed boxes. At the bottom ends of the two fixed boxes, there is a U-shaped fixing frame fixedly connected, and the U-shaped fixing frame is fixedly connected to the two side surfaces of the first conveyor frame. Between the two fixed boxes, there are two loosening frames slidably connected. The two loosening frames are arranged in an upper and lower array. Inside the loosening frame, there are two round-headed plates slidably connected symmetrically. On the mutually distant side surfaces of the round-headed plates, there are a number of sliding columns fixedly connected. The sliding columns penetrate and are slidably connected to the loosening frame. In the middle of the sliding columns, there are springs, and the springs are located between the round-headed plates and the loosening frame.

[0015] Through the above technical solution, the fabric loosening mechanism, through the combination of the loosening frame and the round-headed plate, can beat and loosen the shaped fabric, thereby eliminating any residual stress or wrinkles that may be generated during the shaping process of the fabric. The sliding connection of the round-headed plate and the elastic action of the spring make the loosening action softer and more uniform, avoiding damage to the fabric.

[0016] Furthermore, on one side of the fixed box, there is a motor fixedly connected. The power output end of the motor is located inside the fixed box. The power output end of the motor is fixedly connected to a rotating plate. At the end of the rotating plate away from the motor, there is a push column rotatably connected. The outside of the push column is slidably connected to an annular groove, and the annular groove is fixedly connected to one of the loosening frames. On the adjacent sides of the loosening frames, there are racks fixedly connected respectively. Between the racks, there is a gear meshing and driving connection, and the gear is rotatably connected to the fixed box.

[0017] Through the above technical solution, the introduction of the motor provides a power source for the fabric loosening mechanism. The cooperation of the rotating plate and the push column converts the rotational motion of the motor into the linear motion of the push column, and then pushes the annular groove to drive the loosening frame to perform a reciprocating beating action. The meshing and driving design of the rack and the gear enables the two loosening frames to perform a periodic reciprocating motion in opposite directions, making the loosening action uniform and efficient.

[0018] Furthermore, inside the second conveyor frame, there is an opening conveyor belt rotatably connected. The opening conveyor belt is inclined, and the raised end of the opening conveyor belt is located at the top of the fabric loosening mechanism. Exhaust fans are installed on both sides of the second conveyor frame.

[0019] Through the above technical solution, the design that the raised end is located at the top of the fabric loosening mechanism ensures that the fabric can smoothly transition to being loosened on the opening conveyor belt, avoiding the accumulation or blockage of the fabric. At the same time, the inclined opening conveyor belt, in cooperation with the exhaust fans installed on both sides of the second conveyor frame, helps to discharge the excess moisture or solvent on the fabric, thereby accelerating the drying process of the fabric and reducing the generation of wrinkles.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. Through the design of the hydraulic lifting columns, the processing backing plate of the present utility model can be precisely lifted or lowered as needed, thereby providing stable support for the fabric at different stages, ensuring the flatness of the fabric during the shaping process. The combined use of the first shaping mechanism and the second shaping mechanism enables the fabric to undergo a transverse shaping operation through the second shaping mechanism driven by a smooth conveyor belt after longitudinal shaping by the first shaping mechanism. Through the secondary shaping operation, the shape of the fabric becomes more precise, meeting the requirements for processing high-quality fabrics.

[0022] 2. Through the design of the fabric loosening mechanism and the introduction of the motor and transmission mechanism, the operation of the fabric loosening mechanism becomes more efficient and uniform. At the same time, it reduces the intensity and instability of manual operation, effectively eliminating the residual stress or wrinkles that may occur in the fabric during the shaping process, and ensuring the softness and comfort of the fabric.

Detailed Embodiments

[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] As Figures 1 to 5 shown, a shaping device for fabric production in this embodiment includes a first conveyor frame 1. Inside the first conveyor frame 1, a smooth conveyor belt 2 is rotatably connected. Inside the smooth conveyor belt 2, there are two processing pads 3. The processing pads 3 are fixedly connected to the first conveyor frame 1. On the top of the smooth conveyor belt 2, a first shaping mechanism 7 and a second shaping mechanism 8 are respectively installed. One end of the first conveyor frame 1 is fixedly connected to a fabric loosening mechanism 9. A second conveyor frame 4 is arranged at one end of the first conveyor frame 1 where the fabric loosening mechanism 9 is installed. A fabric placement basket 5 is slidably connected to the end of the second conveyor frame 4 away from the first conveyor frame 1. After the fabric is longitudinally shaped by the first shaping mechanism 7, it is then transversely shaped by the second shaping mechanism 8. Through two shaping operations in different directions, fine shaping can be achieved.

[0031] As Figures 1 to 2 shown, the two processing pads 3 are respectively located at both ends of the first conveyor frame 1. The top ends of the processing pads 3 are slidably fitted with the inner wall of the smooth conveyor belt 2. The two processing pads 3 respectively correspond to the first shaping mechanism 7 and the second shaping mechanism 8. At the bottom ends on both sides of the processing pads 3, hydraulic lifting columns 11 are fixedly connected. The telescopic ends of the hydraulic lifting columns 11 penetrate and slidably connect with the processing pads 3. The telescopic ends of the hydraulic lifting columns 11 are respectively fixedly connected to the first shaping mechanism 7 and the second shaping mechanism 8. When the first shaping mechanism 7 and the second shaping mechanism 8 descend through the hydraulic lifting columns 11 to contact the smooth conveyor belt 2 for work, they perform supporting and auxiliary work, thereby ensuring the fabric shaping effect.

[0032] As Figures 1 to 2 shown, inside the second conveyor frame 4, an open-hole conveyor belt 6 is rotatably connected. The open-hole conveyor belt 6 is inclined. The upturned end of the open-hole conveyor belt 6 is located on top of the fabric loosening mechanism 9, ensuring that the fabric can smoothly transition and be loosened on the open-hole conveyor belt 6. Exhaust fans 33 are installed on both sides of the second conveyor frame 4, which helps to discharge excess moisture or solvents on the fabric, thereby accelerating the drying process of the fabric and reducing the generation of wrinkles.

[0033] As Figure 2 shown, the first shaping mechanism 7 includes a first shaping frame 13. The first shaping frame 13 is fixedly connected to the telescopic end of the hydraulic lifting column 11. Inside the first shaping frame 13, a shaping roller 12 is rotatably connected. The cylindrical surface of the shaping roller 12 is in rotational contact with the smooth conveyor belt 2. The two shaping rollers 12 in the middle of the first shaping frame 13 continuously roll and extend the moving fabric, thereby achieving the shaping effect.

[0034] like Figure 3 As shown, the fabric loosening mechanism 9 includes two fixed boxes 14, the bottom ends of the two fixed boxes 14 are fixedly connected with U-shaped fixed frames 10, the U-shaped fixed frames 10 are fixedly connected to the two side surfaces of the first conveying frame 1, and two loosening frames 18 are slidably connected between the two fixed boxes 14. The two loosening frames 18 are arranged in an upper and lower array, and round head plates 16 are symmetrically slidably connected inside the loosening frames 18. The round head plates 16 are fixedly connected with a plurality of sliding columns 17 on the surface of the side away from each other, and the sliding columns 17 are slidably connected with the loosening frames 18. The fabric loosening mechanism 9 can beat and loosen the shaped fabrics through the combination of the loosening frames 18 and the round head plates 16. A spring 15 is arranged in the middle of the sliding column 17, and the spring 15 is located between the round head plates 16 and the loosening frames 18. The elastic effect of the spring 15 makes the loosening action softer and more uniform, thereby avoiding damage to the fabrics.

[0035] like Figure 4 As shown, a motor 19 is fixedly connected to one side of the fixed box 14, and the power output end of the motor 19 is located inside the fixed box 14. A rotating plate 23 is fixedly connected to the power output end of the motor 19. The rotating plate 23 is rotatably connected to a push column 22 at one end away from the motor 19. An annular groove 20 is slidably connected to the outer side of the push column 22. The annular groove 20 is fixedly connected to one of the loosening frames 18. Racks 24 are respectively fixedly connected to the adjacent sides of the loosening frames 18. Gears 21 are meshingly connected between the racks 24. The gears 21 are rotatably connected to the fixed box 14. The meshing transmission design of the racks 24 and the gears 21 enables the two loosening frames 18 to achieve periodic reciprocating motion in opposite directions, so that the loosening action is uniform and efficient.

[0036] like Figure 5 As shown, the second shaping mechanism 8 includes a second shaping frame 25, which is fixedly connected to the telescopic end of the hydraulic lifting column 11, a partition bar 26 is fixedly connected to the middle of the second shaping frame 25, and fixed slide bars 28 are fixedly connected to both sides of the inside of the second shaping frame 25. The middle part of the fixed slide bar 28 is penetrated and fixedly connected with both ends of the partition bar 26, and a plurality of convex plates 27 are arranged on both sides of the partition bar 26. A shaping plate 31 is fixedly connected to the bottom end of the convex plate 27. The sliding connection of the convex plate 27 and the design of the fixed slide bar 28 ensure the precise position control of the convex plate 27 during the fabric shaping process.

[0037] like Figure 5As shown, both sides of the top of the convex plate 27 are respectively and slidably connected through the fixed slide bar 28. A second limit slide bar 32 is arranged through between several convex plates 27 in pairs. One end of the second limit slide bar 32 is fixedly connected through one of the convex plates 27, and the other end of the second limit slide bar 32 is slidably connected through another convex plate 27. The middle part of the convex plate 27 located outside the second shaping frame 25 is slidably connected through the first limit slide bar 30. One end of the first limit slide bar 30 far from the convex plate 27 is fixedly connected to the second shaping frame 25. Two hydraulic push rods 29 are fixedly connected to the top of the second shaping frame 25. The two hydraulic push rods 29 are symmetrical to each other. The telescopic end of the hydraulic push rod 29 is fixedly connected to a convex plate 27 close to the partition strip 26. By the telescopic action of the hydraulic push rod 29, an appropriate force can be applied to the convex plate 27. The setting of the second limit slide bar 32 enables several convex plates 27 to shrink successively, thereby ensuring the uniformity and consistency of the fabric shaping.

[0038] The working principle of this embodiment is as follows:

[0039] The staff puts the preliminarily produced fabric into the fabric placement basket 5, and then places one end of the fabric on the perforated conveyor belt 6 on the surface of the second conveyor frame 4. The exhaust fans 33 installed on both sides of the second conveyor frame 4 help to discharge excess moisture or solvent on the fabric, thereby accelerating the drying process of the fabric. Since the raised end of the perforated conveyor belt 6 is located at the top of the fabric loosening mechanism 9, it ensures that the fabric can smoothly transition to the loosening treatment on the perforated conveyor belt 6, avoiding the accumulation or blockage of the fabric. When the fabric reaches the fabric loosening mechanism 9, the motor 19 drives the rotating plate 23 to rotate. The cooperation of the rotating plate 23 and the pushing column 22 converts the rotational motion of the motor 19 into the linear motion of the pushing column 22, and then drives the annular groove 20 to drive the loosening frame 18 to perform reciprocating beating action. At the same time, due to the meshing transmission design of the two racks 24 and the gear 21, the two loosening frames 18 can realize periodic reciprocating motion in opposite directions, thereby realizing continuous loosening of the fabric. Then the fabric falls onto the smooth conveyor belt 2, and the fabric is transported on the smooth conveyor belt 2 During the conveying, the two shaping rollers 12 in the middle of the first shaping frame 13 continuously roll and extend the moving fabric, so as to achieve the shaping effect. The rotation of the shaping rollers 12 is consistent with the movement direction of the smooth conveyor belt 2, ensuring that the fabric will not produce unnecessary pulling or wrinkles during the shaping process, and then arrive at the second shaping mechanism 8. The second shaping mechanism 8 can ensure that the convex plate 27 remains stable during the shaping process of the fabric through the structural design of the partition bar 26 and the fixed slide bar 28. At the same time, the sliding connection of the convex plate 27 and the design of the limiting slide bar ensure the precise position control of the convex plate 27 during the shaping process of the fabric. Through the telescopic action of the hydraulic push rod 29, appropriate force can be applied to the convex plate 27. The setting of the second limiting slide bar 32 makes several convex plates 27 shrink successively, so that the fabric is longitudinally shaped by the first shaping mechanism 7, and then the second shaping mechanism 8 performs a transverse shaping operation. Through the secondary shaping operation in different directions, further fine shaping can be obtained, thereby achieving a more perfect shaping effect.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
