DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figures 1 to 6 As shown, a multi-roller feeding mechanism of a horizontal bag throwing machine includes a frame 1 and an elastic traction member 2.

The middle position of the roller transmission device 3 is rotatably connected to the frame 1 through a bearing, the upper end of the roller transmission device 3 is connected to the upper end of the elastic traction member 2, and the lower end of the elastic traction member 2 is connected to the frame 1; the elastic traction member 2 maintains a downward pulling force on the upper end of the roller transmission device 3, so that the lower end of the roller transmission device 3 has a pressing force on the seasoning bag 6.

[0027] Specifically, Figure 2As shown, the driving device 4 includes a motor 401, a plurality of first gears 402, and a second gear 403; a third gear 404 is provided between adjacent first gears 402, and the third gear 404 is used for connecting transmission, mainly for transmitting power; the first gear 402 and the third gear 404 are both rotatably connected to the frame 1; the motor 401 is coaxially connected to the second gear 403, and the motor 401 directly drives the second gear 403 to rotate, and the second gear 403 is meshed and connected with the adjacent first gear 402, and the first gear 402 is meshed and connected with the third gear 404, that is, the second gear 403 will drive the first gear 402 and the third gear 404 to rotate. The third gear 404 is coaxially connected to a connecting shaft 405, and a first synchronous wheel 406 is connected to the connecting shaft 405, and the first synchronous wheel 406 is connected to a first belt 407, and the first belt 407 is connected to a second synchronous wheel 408, and the second synchronous wheel 408 is connected to the conveying device 5; finally, the power is transmitted from the second synchronous wheel 408 to the conveying device 5.

[0028] The roller transmission device 3 includes a main frame 307, on which a transmission shaft 305 and a clamping shaft 306 are rotatably arranged. The transmission shaft 305 and the clamping shaft 306 are both rotatably connected to the main frame 307 through bearings, that is, the power rotation of the transmission shaft 305 and the clamping shaft 306 will not cause the main frame 307 to move; the clamping shaft 306 is used to press on the surface of the seasoning bag 6; the transmission shaft 305 corresponds to the first gear 402 one by one; Figure 2 It can be seen that in this embodiment, the number of first gears 402 is four, the number of roller transmission devices 3 is also four, and the transmission shaft 305 of each roller transmission device 3 corresponds to the first gear 402; it also includes a first coupling 301, one end of the first coupling 301 is connected to the first gear 402, and the other end of the first coupling 301 is connected to the transmission shaft 305, and the other end of the transmission shaft 305 is rotatably connected to the frame 1 through the first bearing 7; therefore, the rotation of the first gear 402 will drive the transmission shaft 305 to rotate through the first coupling 301; the transmission shaft 305 is fixed with a third synchronous wheel 302, the third synchronous wheel 302 is connected to the second belt 303, the second belt 303 is connected to the fourth synchronous wheel 304, and the fourth synchronous wheel 304 is connected to the clamping shaft 306, that is, the rotation of the transmission shaft 305 will eventually drive the clamping shaft 306 to rotate. Therefore, the rotation of the four first gears 402 eventually drives the four clamping shafts 306 of the roller transmission device 3 to rotate simultaneously.

[0029] The main frame 307 includes a first plate body 3071 and a second plate body 3072, and the first plate body 3071 and the second plate body 3072 are connected to form a "7" shape; the transmission shaft 305 is rotatably connected to the upper part of the second plate body 3072, and the clamping shaft 306 is rotatably connected to the lower part of the second plate body 3072; the frame body 1 includes a side plate 101 and a support plate 102, and a cross plate 103 is arranged between the side plate 101 and the support plate 102; the first gear 402, the second gear 403 and the third gear 404 are rotatably arranged on the side plate 101, one end of the transmission shaft 305 is connected to the first coupling 301, and the other end of the transmission shaft 305 is rotatably arranged on the support plate 102 through the first bearing 7.

[0030] from Figure 6 It can be seen that the conveying device 5 includes a second coupling 501, one end of which is connected to the second synchronous wheel 408, and the second synchronous wheel 408 will rotate under the drive of the first synchronous wheel 406. The other end of the second coupling 501 is connected to the driving shaft 502, the driving shaft 502 is connected to the transmission belt 503, and the transmission belt 503 is connected to the driven shaft 504, so that the transmission belt 503 is finally driven to move. The simultaneous movement of the transmission belt 503 and the pressing shaft 306 transmits the seasoning bag 6. Among them, a plurality of auxiliary shafts 505 are rotatably arranged between the driving shaft 502 and the driven shaft 504, and the auxiliary shafts 505 have a load-bearing effect on the middle part of the transmission belt 503, thereby improving the load-bearing effect.

[0031] Combination Figure 5 It can be seen that a second connecting member 1021 is arranged above the support plate 102, and a first connecting member 3073 is arranged at the end of the first plate body 3071, and the number of the second connecting member 1021 and the first connecting member 3073 corresponds to the number of the elastic traction member 2; the upper end of the elastic traction member 2 is connected to the first connecting member 3073, and the lower end of the elastic traction member 2 is connected to the second connecting member 1021; the elastic traction member 2 has a downward pulling force on the first plate body 3071, so that the clamping shaft 306 is pressed on the surface of the conveyor belt 503; when the clamping shaft 306 enters the seasoning bag 6 between the surface of the conveyor belt 503, the clamping shaft 306 will be lifted up, but due to the elastic pulling force of the elastic traction member 2, the clamping shaft 306 will be tightly pressed against the surface of the seasoning bag 6 and rotate, and the transmission effect is good.

[0032] The working principle of the multi-roller feeding mechanism of the horizontal bag throwing machine is that the driving device can simultaneously drive the roller transmission device 3 and the conveying device 5 to rotate, thereby driving the seasoning bag 6 to carry out the transportation operation; the upper end of the main frame 307 of the roller transmission device is connected to an elastic traction member 2, and the elastic traction member 2 has a downward tightening effect on the upper end of the main frame 307. Before feeding, the clamping shaft 306 will be pressed on the surface of the conveyor belt 503, and when the seasoning bag 6 enters between the clamping shaft 306 and the surface of the conveyor belt 503, the clamping shaft 306 will be lifted up, and the main frame 307 will have a certain angle of rotation, but due to the elastic tension of the elastic traction member 2, the clamping shaft 306 will still be pressed against the surface of the seasoning bag 6 and rotate, and the transmission effect is good; when the seasoning bag 6 leaves, the main frame 307 will be reset under the pull of the elastic traction member 2, and return to being pressed on the surface of the conveyor belt 503, waiting for the next seasoning bag 6 to enter. This structure is compatible with the conveying of seasoning packets 6 with slightly different thicknesses, and can also have a better compression and conveying effect.
