Specific implementation

[0023] In order to make the technical means, creation features, achieve the purpose and effect of the utility model easy to understand, the following specific implementation is further described.

[0024] As Figures 1-3 Shown, a weaving bag reversing conveying device based on conveying belt, including conveyor 1, the conveyor 1 one end is provided with frame 2, frame 2 in both sides rotationally connected with roller body 302, frame 2 is fixed with first motor 301, the power output shaft of first motor 301 is fixedly connected with one of roller body 302, and the two roller bodies 302 are connected through a plurality of belts 303, frame 2 one side rotationally connected with rotating roller 4, still include second motor 8, the drive end of second motor 8 is fixedly connected with rotating roller 4, the rack 101 of conveyor 1 is fixed with swing down -pressing device 5 with rotating roller 4 position matching, swing down -pressing device 5 is used to be held weaving bag with rotating roller 4 cooperation to convey weaving bag to conveyor 1.

[0025] In the embodiment, as Figure 1 And Figure 2 Shown, swing down -pressing device 5 includes two vertical plates 504 opposite fixed on the rack 101 of conveyor 1, two vertical plates 504 are rotationally connected with pivot 506 between, one of vertical plates 504 is fixed with rotary cylinder 505, the drive end of rotary cylinder 505 is fixedly connected with pivot 506, pivot 506 is fixed with two connecting plates 503, two connecting plates 503 are rotationally connected with press roll 501 between.

[0026] When the first motor 301 works, it drives the roller body 302 connected therewith to rotate, thereby driving the other roller body 302 to rotate by means of the belt 303, and further realizing the transmission work of the belt 303. When the woven bag is placed on the belt 303, the belt 303 will drive the woven bag to move. When the woven bag moves to the feeding end of the conveyor 1, the first motor 301 stops working, and then the rotary cylinder 505 works, thereby driving the rotating shaft 506 to rotate, and further driving the compression roller 501 to swing by means of the connecting plate 503, so as to make the compression roller 501 press one side of the woven bag on the rotating roller 4. The rotating roller 4 is driven by the second motor 8. Therefore, when the woven bag is clamped by the compression roller 501 and the rotating roller 4 (the clamping force of the compression roller 501 and the rotating roller 4 on the woven bag is less than the conveying force of the rotating roller 4 on the woven bag), the rotating rotating roller 4 will exert force on the woven bag, thereby making the woven bag be conveyed to the conveyor 1 under force. The conveyor 1 works, and can continue to convey the woven bag, so as to complete the reversing conveying work of the woven bag.

[0027] As shown in Figure 2 , the compression roller 501 is fixed with a plurality of compression rings 502. The compression roller 501 presses the woven bag by means of the compression rings 502, so that the woven bag is in contact with the rotating roller 4. The contact area between the compression ring 502 and the woven bag is small, and the friction force is also small, thereby avoiding that the woven bag cannot be conveyed by the rotating roller 4 due to the large friction force.

[0028] One of the connecting plates 503 can also be provided with a third motor. The third motor is fixedly connected with the compression roller 501, and is used for driving the compression roller 501 to rotate. The rotating directions of the compression roller 501 and the rotating roller 4 are opposite, so as to cooperate with the rotating roller 4 to convey the woven bag.

[0029] As shown in Figure 1 , a plurality of bearing plates 7 are mounted on the top of the frame body 2. The top height of the bearing plate 7 is the same as the top height of the belt 303. Therefore, when the belt 303 conveys the woven bag, the bearing plate 7 can support the woven bag.

[0030] As shown in Figure 1 , the conveying path of the belt 303 is perpendicular to the conveying path of the conveyor 1, thereby realizing the vertical circular reversing work of the woven bag.

[0031] As shown in Figure 1 , a groove 6 for the woven bag to pass through is formed on the side of the top of the frame body 2 close to the conveyor 1. The inner bottom height of the groove 6 is the same as the top height of the rotating roller 4. Therefore, when the rotating roller 4 conveys the woven bag, the woven bag can more easily pass through the frame body 2 and move to the conveyor 1.

[0032] The working principle is that firstly, the first motor 301 and the second motor 8 are controlled to work, the first motor 301 works to drive the roller body 302 connected with the first motor 301 to rotate, thereby driving the other roller body 302 to rotate through the belt 303, and the transmission work of the belt 303 is realized, the second motor 8 works to drive the rotating roller 4 to work, then when the woven bag is placed on the belt 303, the belt 303 drives the woven bag to move, when the woven bag moves to the feeding end of the conveyor 1, the first motor 301 stops working, then the rotary cylinder 505 works, thereby driving the rotating shaft 506 to rotate, and the connecting plate 503 drives the pressing roller 501 to swing, so that the pressing roller 501 presses one side of the woven bag on the rotating roller 4, at this time, the rotating roller 4 exerts force on the woven bag, thereby driving the woven bag to be conveyed to the conveyor 1, the conveyor 1 works to continuously convey the woven bag, so that the reversing conveying work of the woven bag is completed.

[0033] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by the person skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only for illustrating the principle of the utility model, and the utility model can have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
