[0030] The non-woven vest bag is a bag made of non-woven fabric and shaped like a vest. It is a new generation of environmentally friendly materials with the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable. The sewing device is mainly used for the hemming, welding, melting and embossing of synthetic fiber fabrics. The processed products have good water tightness, high production efficiency, no need for needle and thread accessories, smooth melting and cutting surface without burrs, and good hand feel.

[0031] However, when the current non-woven fabric sewing mechanism sews the edge of the vest bag, in order to facilitate the sewing operation of the sewing machine, the non-woven fabric bag needs to be transported. If the edge of the non-woven fabric bag is lifted during the conveying process, the sewing effect of the bag will be affected; and the conveying position of the bag is prone to deviation, which will cause the non-woven fabric bag to be misplaced. The operation of repositioning the non-woven fabric bag is cumbersome, which reduces production efficiency.

[0032] Based on this, the technical problems existing in the related art that when the sewing device is sewing, the edge of the bag is prone to warping or the sewing position of the bag is prone to deviation, which affects the sewing effect, can be improved. The embodiments of the present application provide the following solutions.

[0033] Please also read Figures 1 to 4 The embodiment of the present application provides a non-woven vest bag sewing device, including a frame 10, a sewing device 20, a conveying device 30, a rolling assembly 40, and a limiting assembly 50. The sewing device 20 and the conveying device 30 are both arranged on the frame 10. The frame 10 includes a fixed platform 11. The conveying device 30 includes a conveyor belt 31. The fixed platform 11 is provided with a groove 12 to install the conveyor belt 31.

[0034] The rolling assembly 40 includes a first pressing roller 41 and a second pressing roller 42 disposed on one side of the conveyor belt 31, wherein the first pressing roller 41 is disposed directly below the second pressing roller 42, the first pressing roller 41 is slidably mounted on the fixed platform 11 through a control assembly 60, and the second pressing roller 42 is rotatably mounted on the fixed platform 11, and the control assembly 60 is used to control the sliding position of the first pressing roller 41;

[0035] The limiting assembly 50 includes a fixed frame 51, a main pressure roller 52 and a plurality of telescopic members 53. The fixed frame 51 is arranged on the fixed platform 11. The fixed end of the telescopic member 53 is arranged on the fixed frame 51. The telescopic end is rotatably connected to the main pressure roller 52 through a rotating shaft. The main pressure roller 52 is against the top side wall of the conveyor belt 31.

[0036] As can be seen from the above, in a non-woven vest bag sewing device provided by an embodiment of the present application, when it is necessary to sew the bag, the control component 60 is started to move the first pressing roller 41 to a suitable position, the bag is placed on the conveyor belt 31, the conveying device 30 is started, and the bag is conveyed. The edge of the bag first passes through the gap between the first pressing roller 41 and the second pressing roller 42, and the side walls on both sides of the edge of the bag are respectively against the side walls of the first pressing roller 41 and the second pressing roller 42 for pressing and limiting processing; when the edge of the bag moves to the sewing device 20 for sewing, the main pressing roller 52 is rotated to the top of the bag through the telescopic member 53, and is against the top plate of the bag under the action of gravity. The bag is abutted between the conveyor belt 31 and the main pressing roller 52 as a whole, and its conveying position is difficult to deviate; therefore, the first pressing roller 41 and the second pressing roller 42 reduce the probability of the bag warping, and the setting of the fixed frame 51, the main pressing roller 52 and the plurality of telescopic members 53 reduces the probability of the bag conveying position deviation.

[0037] Optionally, in some embodiments, please read Figure 1 to Figure 2 The control assembly 60 includes a bracket 61, a slider 62 and a screw 63. The bracket 61 is set on the fixed platform 11. The bracket 61 is slidably installed with the slider 62 by opening a slide groove 611. The sliding direction of the slider 62 is perpendicular to the conveying direction of the conveyor belt 31. The screw 63 passes through the bracket 61 and is rotatably connected to the slider 62. The slider 62 is rotatably connected to the first pressure roller 41.

[0038] With such arrangement, when it is necessary to move the first pressure roller 41, the screw 63 is rotated, the screw 63 moves on the fixed frame 51, and drives the slider 62 to move in the slide groove 611, so that the first pressure roller 41 moves along a direction close to or away from the second pressure roller 42, thereby achieving the purpose of controlling the sliding position of the first pressure roller 41. After adjusting the moving position of the first pressure roller 41, the conveying device 30 is started to convey the bag, and the edge of the bag first passes through the gap between the first pressure roller 41 and the second pressure roller 42. The side walls on both sides of the edge of the bag respectively abut against the side walls of the first pressure roller 41 and the second pressure roller 42 for pressing and limiting processing; therefore, the arrangement of the bracket 61, the slider 62 and the screw 63 facilitates the staff to control the sliding position of the first pressure roller 41.

[0039] Optionally, in some embodiments, see Figure 3 The slider 62 is provided with a motor 64 , and the output end of the motor 64 passes through the slider 62 and is connected to the first pressing roller 41 .

[0040] With such arrangement, after adjusting the sliding position of the first pressing roller 41, when the bag needs to be sewn, the bag is placed on the conveyor belt 31, the conveying device 30 is started, the bag is conveyed, and the edge of the bag first passes through the gap between the first pressing roller 41 and the second pressing roller 42. The side walls on both sides of the edge of the bag respectively abut against the side walls of the first pressing roller 41 and the second pressing roller 42. The motor 64 is started, the first pressing roller 41 rotates, and the edge of the bag is conveyed. Therefore, the setting of the motor 64 is used to reduce the probability of folding due to the edge of the bag being stuck in the gap between the first pressing roller 41 and the second pressing roller 42, and the conveying speed of the first pressing roller 41 is the same as the conveying speed of the conveyor belt 31, which is used to reduce the probability of folding of the bag due to the first pressing roller 41 rotating too fast or too slow.

[0041] Optionally, in some embodiments, see Figures 2 to 3 The telescopic member 53 includes a fixed sleeve 531 and a slide rod 532 . The fixed sleeve 531 is arranged on the fixed frame 51 . One end of the slide rod 532 is slidably installed at the bottom of the fixed sleeve 531 , and the other end is rotatably connected to one end of the main pressure roller 52 .

[0042] With such arrangement, when the bag is conveyed to the main pressure roller 52, the main pressure roller 52 moves upward, and the slide bar 532 moves upward until the main pressure roller 52 slides and fits against the side wall of the bag. The main pressure roller 52 abuts against the top plate of the bag under the action of gravity, and the bag as a whole abuts between the conveyor belt 31 and the main pressure roller 52, so that its conveying position is unlikely to deviate. Therefore, the arrangement of the fixing sleeve 531 and the slide bar 532 facilitates the main pressure roller 52 to move to the top of the bag and fix the bag, so that its conveying position is unlikely to deviate.

[0043] Optionally, in some embodiments, see Figures 2 to 3 A contact plate 13 is disposed in the groove 12 , and the top of the conveyor belt 31 abuts between the contact plate 13 and the main pressure roller 52 .

[0044] With such arrangement, when the bag is conveyed to the main pressure roller 52, the main pressure roller 52 moves upward, and the slide bar 532 moves upward until the main pressure roller 52 slides and fits against the side wall of the bag, and the main pressure roller 52 abuts against the top plate of the bag under the action of gravity, and the bag as a whole abuts between the conveyor belt 31 and the main pressure roller 52, and the top of the conveyor belt 31 abuts between the abutment plate 13 and the main pressure roller 52. Therefore, the arrangement of the abutment plate 13 makes it difficult for the top of the conveyor belt 31 to dent when the main pressure roller 52 generates downward pressure on the conveyor belt 31, thereby reducing the probability of warping at the edge of the bag and improving the sewing effect of the bag.

[0045] Optionally, in some embodiments, see Figure 1 to Figure 2A limiting plate 14 is installed on the fixed platform 11 , and a moving groove is opened on the limiting plate 14 . The limiting plate 14 is arranged between the suturing device 20 and the rolling assembly 40 .

[0046] With such arrangement, after the edge of the bag is pressed and limited by the rolling assembly 40, it moves into the movable groove under the transmission of the conveyor belt 31, and is then transmitted to the sewing device 20 by the conveyor belt 31 for sewing; therefore, the arrangement of the limiting plate 14 and the movable groove can cooperate with the main pressure roller 52 to limit the bag, and make it difficult for the bag to be misplaced after passing through the rolling assembly 40.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
