[0002] As people's demand for clothing comfort continues to increase, more and more knitted fabrics, especially high-elastic fabrics such as Modal and Lycra, are being used in garment making. However, if these high-elastic fabrics are laid out by hand, the efficiency is low and the tension is difficult to control. Even with some common laying devices, it is difficult to achieve the ideal tension. Excessive tension on the fabric causes significant deformation, reducing the quality of the fabric laying. In severe cases, deformation of the warp and weft yarns can occur, affecting the quality of the finished garment. Summary of the Invention

They should not be construed as limiting the specific protection scope of this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this invention, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0023] Reference Figures 1 to 7 The present invention will be further described below.

[0024] A half-width tracked conveyor type fabric laying device includes a frame 1. The frame 1 is equipped with a walking mechanism 2, a fabric loosening mechanism 3, a tension adjustment mechanism, a conveying mechanism 5, a shearing mechanism 6, and a lifting mechanism 7. The conveying mechanism 5 includes a conveying support 51 and a conveying motor. The two ends of the conveying support 51 are respectively rotatably connected to a conveying drive roller 52 and a conveying driven roller 53. A conveying flat belt 54 is arranged between the conveying drive roller 52 and the conveying driven roller 53. The conveying motor is connected to the conveying drive roller 52. A vibrating support 55 is arranged on the conveying support 51. A vibrating motor 56 is arranged on the vibrating support 55. A vibrating roller 57 is rotatably connected to the conveying support 51. The vibrating roller 57 abuts against the lower part of the conveying flat belt 54. The cross-section of the vibrating roller 57 is polygonal. The vibrating roller 57 is connected to the vibrating motor 56.

[0025] Preferably, the frame 1 is provided with a cloth loosening groove 36, and the cloth loosening mechanism 3 is located in the cloth loosening groove 36.

[0026] like Figures 1 to 7 As shown, during fabric laying, the roll of fabric is placed in the loosening trough 36. The loosening mechanism 3 causes the roll of fabric to rotate and open. After passing through the tension adjustment mechanism, it moves to the conveyor belt 54. The conveyor motor starts and drives the conveyor drive roller 52 to rotate, causing the conveyor belt 54 to circulate. The fabric is then conveyed to the shearing mechanism 6 via the conveyor belt 54. At the same time, the frame 1 is moved by the walking mechanism 2. When the fabric has been laid to a certain length, it is cut by the shearing mechanism 6. Then, the shearing mechanism 6 is lifted by the lifting mechanism 7, and the frame 1 moves again to continue laying another layer of fabric on top of the already laid fabric, thus completing the laying of multiple layers of fabric.

[0027] Simultaneously with the start of the conveyor motor to transport the fabric, the vibrating motor 56 starts, driving the vibrating roller 57 to rotate. This causes the edges of the vibrating roller 57 to contact the conveyor belt at intervals. When the edges contact the conveyor belt, the surface of the conveyor belt bulges slightly. When the edges of the vibrating roller 57 separate from the conveyor belt, the conveyor belt returns to its original position. Thus, during the continuous and rapid rotation of the vibrating roller 57, the conveyor belt is rapidly raised and reset, achieving vibration of the conveyor belt. This releases the tension on the fabric during transport, thereby reducing the tension on the fabric during laying and improving the laying quality of the fabric.

[0028] Preferably, the cross-section of the vibrating roller 57 is square.

[0029] like Figure 6As shown in the preferred embodiment, the tension adjustment mechanism includes a tension roller 41. Connecting arms 42 are provided at both ends of the tension roller 41. The connecting arms 42 are rotatably connected to the frame 1, and a main drive gear 43 is provided on the rotating shaft of the connecting arm 42. A secondary drive gear 44 meshes with one side of the main drive gear 43. An angle sensor 45 is provided on the secondary drive gear 44. When the fabric is fed out from the transfer roller 34, it passes under the tension roller 41. When the tension on the fabric changes, the connecting arm 42 rotates, causing the secondary drive gear 44 to rotate via the active drive gear. This causes the angle sensor 45 to generate an angle signal, which is transmitted to the control system. The control system then controls the rotation of the fabric unwinding motor to control the unwinding speed of the rolled fabric. By controlling the unwinding speed, the tension on the fabric can be adjusted.

[0030] like Figure 4 As shown, in this preferred embodiment, the lifting mechanism 7 includes a lifting bracket 71, a lifting motor 72, a lifting drive sprocket 73, and a lifting driven sprocket 74. The lifting drive sprocket 73 and the lifting driven sprocket 74 are connected by a transmission chain 78. The lifting motor 72 is fixed to the frame 1. The lifting bracket 71 is connected to the transmission chain 78. The conveying drive roller 52 is rotatably connected to the lifting bracket 71. A support rod 75 is provided at one end of the conveying bracket 51 away from the lifting bracket 71. A support wheel 76 is rotatably connected to the frame 1, and a support plate 77 is provided on the frame 1. The support wheel 76 rolls on the support plate 77. The shearing mechanism 6 is located on the lifting bracket 71. When the lifting motor 72 is started, it drives the lifting drive sprocket 73 and the lifting driven sprocket 74 to rotate, causing the transmission chain 78 to move. This allows the lifting bracket 71 to move up and down with the transmission chain 78, thereby raising or lowering the shearing mechanism 6. At the same time, it changes the conveying angle of the conveying bracket 51, so that the conveyor belt 54 can follow the shearing mechanism 6 to be raised and then lowered.

[0031] When the conveying support 51 rotates, it can be supported by the support rod 75.

[0032] like Figure 4 As shown in this embodiment, preferably, a guide rod 79 is provided on one side of the lifting bracket 71 on the frame 1, and guide wheels 710 located on both sides of the guide rod 79 are rotatably connected to the lifting bracket 71. The guide wheels 710 are in rolling connection with the guide rod 79 to improve the stability of the lifting bracket 71 when it is raised or lowered.

[0033] like Figure 7As shown, in this preferred embodiment, the fabric loosening mechanism 3 includes a fabric loosening motor, a fabric loosening active roller 31, several fabric loosening auxiliary rollers 32, a one-way transmission gearbox 33, and a transfer roller 34. The fabric loosening motor is chain-driven to the fabric loosening active roller 31, the fabric loosening active roller 31 is chain-driven to the one-way gearbox, the transfer roller 34 is provided with a clutch mechanism 35, and the one-way transmission gearbox 33 is chain-driven to the clutch mechanism 35.

[0034] Preferably, there are two active fabric loosening rollers 31, and the two active fabric loosening rollers 31 are connected by chain drive. When laying the fabric, the roll of fabric is placed on the two active fabric loosening rollers 31. After starting the fabric loosening motor, the two active fabric loosening rollers 31 can be driven to rotate, thereby driving the roll of fabric to rotate and loosen the fabric. The auxiliary fabric loosening rollers 32 on both sides can block the roll of fabric and prevent it from separating from the active fabric loosening rollers 31.

[0035] Preferably, the one-way gearbox and clutch mechanism 35 enable the transfer roller 34 to always rotate in one direction when transferring the fabric, thus ensuring the stability of the fabric transfer.

[0036] like Figure 2 As shown in the preferred embodiment, the walking mechanism 2 includes a walking motor 21, a walking drive wheel 22, and a walking driven wheel 23. A linkage shaft 24 is provided between the walking motor 21 and the walking drive wheel 22. The walking motor 21 is chain-driven to the linkage shaft 24, and the linkage shaft 24 is chain-driven to the walking drive wheel 22. When laying the cloth, the walking motor 21 is started to drive the walking drive wheel 22 to rotate through the linkage shaft 24, so that the frame 1 moves on the platform. Moreover, through the linkage rotation, both walking drive wheels 22 on both sides of the frame 1 can receive the transmission force, thereby improving the stability of the frame 1 when moving.

[0037] like Figure 5 As shown in the preferred embodiment, the frame 1 is provided with a length measuring mechanism 8, which includes a length measuring bracket 81. One end of the length measuring bracket 81 is hinged to the frame 1. A length measuring wheel 82 and an encoder 83 are rotatably connected to the length measuring bracket 81. The length measuring wheel 82 and the encoder 83 are connected by a belt drive. A compression spring 84 is provided above the length measuring bracket 81. One end of the compression spring 84 abuts against the length measuring bracket 81, and the other end is connected to the frame 1. When the frame 1 moves, the length measuring wheel 82 rolls on the platform with the frame 1 and drives the encoder 83 to rotate. The encoder 83 can measure the moving speed and moving distance of the frame 1. The encoder 83 transmits the measured data to the control system, and the control system controls the walking motor 21 to ensure the accuracy of each cloth laying and improve the cloth laying quality.

[0038] The elastic force of the compression spring 84 can increase the friction between the measuring wheel 82 and the platform, reduce the mutual sliding between the measuring wheel 82 and the platform, and thus improve the measurement accuracy.

[0039] like Figure 3 and Figure 4 As shown in the preferred embodiment, the conveying support 51 is provided with an adjusting support 58, the conveying driven roller 53 is rotatably connected to the adjusting support 58, and the adjusting support 58 is threadedly connected to an adjusting screw 59. The adjusting screw 59 is rotatably connected to the conveying support 51, that is, by rotating the adjusting screw 59, the adjusting support 58 can be moved on the conveying support 51, thereby tensioning the conveying flat belt 54 through the conveying driven roller 53.

[0040] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
