[0026] Referring to the accompanying drawings, the feeding mechanism of this rod-shaped material has a feed turntable 1, a transverse feeding belt 3, a longitudinal feeding belt 5, a frame 2 and a discharge pallet 4, the transverse feeding belt 3 is provided with a fixed material entry section 45, and a swingable feeding track 8 is provided on the transverse feeding belt 3, the swingable feeding track 8 is hinged to the material entry section 45 through a hinge shaft 6, and a swing cylinder 7 is installed on the frame of the transverse feeding belt 3, and the push rod of the swing cylinder 7 is fixedly connected to the swingable feeding track 9, so that when the swing cylinder 7 is working, the feeding track 8 can be driven to swing back and forth. At least two dividing channels 16 are provided at the end of the swingable feeding track 9. In the present embodiment, three dividing channels 16 are provided. The number of the longitudinal feeding 5 corresponds to the dividing channels 16. Therefore, after the rod-shaped materials are transported by the swingable feeding track 8, they can enter each dividing channel 16 and the corresponding longitudinal feeding belt 5 respectively; wherein the longitudinal feeding belt 5 has a slow feeding belt 10 and a fast feeding belt 9. The purpose of setting the feeding belts with different speeds is to separate the distances between the materials to facilitate subsequent operations. The frame 2 is provided with a feeding rack 15, and the fast feeding belt 9 is adjacent to the feeding rack 15, so that the material on the fast feeding belt 9 can be pushed onto the feeding rack 15, and the feeding rack 15 is provided with an uphill section 11 and a stable section 12, and the feeding rack 15 of the uphill section 11 and the stable section 12 is provided with a circulating transmission belt, and the circulating transmission belt is two parallel chains 13, and the two parallel chains 13 are connected with a baffle plate 14, and the height of the baffle plate 14 is roughly equivalent to the diameter of the rod-shaped material. In order to make the drawings simple, only part of the chain is shown in the figure. The number of the circulating transmission belts corresponds to the material distribution channel 16, that is, the number of the longitudinal feeding belts 5. When the material is sent to the feeding rack 15 through the fast feeding belt 9, the circulating transmission chain 13 with the baffle plate 14 will carry the rod-shaped plastics one by one from the uphill section 11, and then smoothly transport through the stable section 12. A first material receiving hopper 17 is provided on the feeding rack 15 at the end of the stable section 12, a counting electric eye 19 is provided between the stable section 12 and the first material receiving hopper 17, a second material receiving hopper 18 is provided below the first material receiving hopper 17, and the discharge ports of the first material receiving hopper 17 and the second material receiving hopper 18 are both provided with openable and closable baffles 21 and 22, a material trough 35 is provided above the discharge support plate 4, a radially movable valve plate 36 is provided in the material trough 35, and an axially movable first material leveling plate is provided in the material trough 36, a push plate 26 is provided on the discharge support plate 4, and a movable second material leveling plate 29 is provided in the second material receiving hopper 18.After the rod-shaped material is conveyed through the stable section 12, it falls into the first receiving hopper 17 and is counted by the counting electric eye 19. When the set number is reached, the baffle 21 at the discharge port of the first receiving hopper 17 is opened, and a certain amount of material falls into the second receiving hopper 18. At this time, the second material leveling plate 29 in the second receiving hopper 18 moves to push the rod-shaped material falling into the second receiving hopper 18, and then the baffle 22 at the discharge port of the second receiving hopper 18 is opened, and the rod-shaped material falls into the material trough 35. After the first axially moving material leveling plate pushes it neatly, the valve plate 36 is opened, and the rod-shaped material falls onto the discharge support plate 4, and is pushed to the next bagging process by the push plate 26, wherein the push plate 26 is installed on the chain and moves with the chain.

[0027] Among them, the baffles 21 and 22 that can be opened and closed at the discharge ports of the first and second receiving hoppers are operated as follows: the baffle 22 at the discharge port of the second receiving hopper 18 is connected to the first cylinder 24, and the baffle 22 at the discharge port of the second receiving hopper 18 is linked with the baffle 21 at the first receiving hopper 17 through a connecting rod structure 23. This connecting rod structure 23 is a commonly used technical means, which is formed by multiple hinged connecting rods and will not be repeated. When the first cylinder 24 is operated to open the baffle 22 at the discharge port of the second receiving hopper 18, the baffle 21 at the discharge port of the first receiving hopper 17 is in a closed state; when the first cylinder 24 is operated to close the baffle 22 at the discharge port of the second receiving hopper 18, the baffle 21 at the discharge port of the first receiving hopper 17 is in an open state.

[0028] The second receiving hopper 18 is provided with a movable second material leveling plate 29 which is moved in the following manner: a material leveling cylinder 46 is mounted on the frame 2, and a push rod of the material leveling cylinder 46 is connected to the second material leveling plate 29. Therefore, when the material leveling cylinder 46 is working, it pushes the second material leveling plate 29 to move and align the materials.

[0029] The frame 2 is provided with a second cylinder 44 , which is connected to the valve plate 36 . The movement of the second cylinder 44 can pull the valve plate 36 to drop the material in the trough 35 onto the discharge support plate 4 .

[0030] In this embodiment, a mobile frame 30 is arranged above the discharging support plate 4, and the material trough 35 is arranged on the mobile frame 30. The material trough 35 and the first material leveling plate constitute a material bin, and the rod-shaped material dropped from the second receiving hopper 18 falls into the material bin. The number of the material bins corresponds to the number of the material distribution channels 16. A guide rod 28 is installed on the mobile frame 30, and the first material leveling plate is sleeved on the guide rod 28, and the outermost first material leveling plate is connected to the third cylinder 31. There are three material bins in this embodiment, so there are six first material leveling plates 32a, 32b, 32c, 32d, 32e, and 32f, that is, each material bin has two left and right first material leveling plates, and the shaft sleeves 33 constituting the first material leveling plates of each material bin are in contact with each other, and a spring 34 is sleeved on the guide rod 28 between the first material leveling plates between two adjacent material bins. Therefore, in this embodiment, there are two outermost third cylinders, namely third cylinders 31 and 38. When the third cylinders are working, they can simultaneously push the first material alignment plates 32a, 32b, 32c, 32d, 32e, and 32f to achieve the sorting and alignment of the rod-shaped materials. When the third cylinders 31 and 38 return to their original positions, they all return to their original positions due to the action of the spring 34.

[0031] A servo motor 27 and a synchronous wheel 43 are provided on the frame 2, a synchronous belt 32 is wound around the synchronous wheel 43, one of the synchronous wheels is connected to the servo motor 27 in driving connection, the mobile frame 30 is connected to the synchronous belt 32, and the mobile frame 30 is installed on the slide rail 42 through a slider. The servo motor 27 and the synchronous wheel 43 are arranged so that after the materials in the silo are pushed neatly and before the valve plate 36 is actuated, the neatened materials are pushed forward for a distance, so that after the valve plate 36 is opened, the rod-shaped materials can fall between the corresponding push plates 26 on the discharge tray 4, so that the rod-shaped materials are pushed by the push plate on the discharge tray to enter the next process.
