DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Figure 1 1 is an overall schematic diagram of a discharge port docking device 20 of a baler 10 according to an embodiment of the present invention. The discharge port docking device 20 is disposed on one side of the baler 10 to remove tobacco leaves to be baled. Specifically, the discharge port docking device 20 includes a plurality of limiting plates 100, at least two first limiting assemblies 200, and at least one second limiting assembly 300.

[0033] A plurality of limiting plates 100 form a discharge port 101, and the tobacco leaves to be packaged are sent out from the discharge port 101. A plurality of limiting plates 100 can form a discharge port 101 with different cross-sectional shapes, such as a triangle, a quadrilateral or a pentagon, etc. In the present invention, the discharge port 101 adopts a quadrilateral.

[0034] Please also refer to Figure 1 and Figure 2At least two first limit assemblies 200 are respectively arranged on opposite sides of the plurality of limit plates 100. In a specific embodiment, two first limit assemblies 200 form a group and are respectively arranged on both sides of the discharge port 101. The first limit assemblies 200 may be multiple groups. Each first limit assembly includes a first guide plate 210, which is rotatably connected to the limit plate or the housing of the baler 10 through a fixing member 213. The specific connection method is described below.

[0035] Furthermore, the first guide plate 210 includes a guide portion 211 and a stopper portion 212. A gap is formed between the end of the guide portion 211 and the stopper plate 100. When the hard box is docked with the discharge port docking device 20, the gap gives way for the hard box to dock with the discharge port 101, so that the interface of the hard box can be easily and smoothly docked with the discharge port 101.

[0036] One end of the limiting part 212 is connected to the guide part 211, and the other end is rotatably connected to the fixing member. The fixing member 213 includes a rotating shaft 2131, and the end of the limiting part 212 is rotatably connected to the rotating shaft 2131 so that the limiting part 212 moves closer to or away from the limiting plate 100. Specifically, the fixed end 2121 of the limiting part 212 is fixed to the limiting plate 100 or the housing of the baler 10 through the fixing member 213, and the free end 2122 of the limiting part 212 is smoothly connected to the guide part 211. When the box is not pushed into the limiting part 212, the free end 2122 of the limiting part 212 is close to the limiting plate 100. Under the action of the box pushing pressure, the free end 2122 of the limiting part 212 gives way for the hard box to continue to move toward the inside of the discharge port 101. The free end 2122 of the limiting part 212 forces the fixed end 2121 to rotate on the fixing part, so that the free end 2122 is away from the limiting plate 100. After the hard box moves to the predetermined position, the limiting part 212 abuts against the outside of the hard box, so that the hard box and the limiting plate 100 are in close contact. When the tobacco leaves to be packaged are sent out from the discharge port 101, there is an outward impulse on the hard box. Due to the existence of the limiting part 212, the friction between the hard box and the limiting part 212 can be prevented from being greater than the outward impulse, so that the hard box can be firmly docked with the discharge port 101, ensuring that the tobacco leaves are smoothly and completely sent into the hard box.

[0037] In some preferred embodiments, the central axis of the first guide plate 210 coincides with the central axis of the limiting plate 100. When the central axes of the two coincide, the hard box and the discharge port 101 are accurately positioned in the transverse direction, so that when the hard box and the discharge port 101 are docked, deviation is not likely to occur, thereby reducing the probability of docking failure.

[0038] Furthermore, a first elastic member 220 is connected between the first limiting assemblies 200 that are arranged oppositely. One end of the first elastic member 220 is fixedly connected to a fixed end 2121 of a limiting portion 212 of a first guide plate 210 that is arranged oppositely, and the other end is fixedly connected to a fixed end 2121 of a limiting portion 212 of another first guide plate 210. The first elastic member 220 can be, but is not limited to, a spring. After the hard box moves to a predetermined position, the limiting portion 212 abuts against the outside of the hard box, and the first elastic member 220 is stretched. The resilience of the first elastic member 220 can make the limiting portion 212 apply more pressure to increase the friction between the limiting portion 212 and the box. When the box exits the discharge port 101, the first elastic member 220 returns to its original state, thereby driving the limiting portion 212 to rotate along the rotating shaft 2131 and then move closer to the limiting plate 100, so that the limiting portion 212 returns to its original state.

[0039] Please also refer to Figure 1 and Figure 3 , at least one second limiting assembly 300 is arranged at the discharge end of the discharge port 101, and at least one is arranged at the upper and lower parts of the discharge port 101. In a specific embodiment, the second limiting assembly 300 includes two, the two second limiting assemblies are arranged opposite to each other, the central axis coincides with the central axis of the limiting plate 100, and the hard box is accurately positioned in the longitudinal direction of the discharge. Each second limiting assembly includes a second guide plate 310 and a slide groove 320, the slide groove 320 is arranged on the side of the limiting plate 100 facing outward, one end of the second guide plate 310 moves in the slide groove 320; the other end protrudes out of the discharge port 101, and the other end is inclined toward the discharge port 101. The second guide plate 310 is connected to the end of the limiting plate 100 where it is located by a second elastic member 330. The second elastic member 330 can be, but is not limited to, a torsion spring.

[0040] The second guide plate 310 and the slide groove 320 are connected via a sliding plate 340 ; one side of the sliding plate 340 is rotationally connected to the second guide plate 310 , and the other side of the sliding plate 340 is slidingly connected to the slide groove 320 .

[0041] The front end of the second guide plate 310 is narrow in front and wide in the back. Before the hard box docks with the discharge port 101, the hard box may change from a folded state to a three-dimensional state, and the opening of the hard box may be concave, resulting in a cross-sectional area of ​​the opening being smaller than the cross-sectional area of ​​the discharge port 101. The end of the second guide plate 310 close to the discharge port 101 is tilted toward the discharge port 101, so that the hard box is opened by the second guide plate 310 before entering the discharge port 101. When the hard box moves toward the inner side of the discharge port 101, it first contacts the narrow surface, so that it is easier to prop up a gap at the end of the hard box. The end of the second guide plate 310 located on the upper side of the discharge port 101 moves in the Y direction under the action of the second elastic member 330 (the movement direction of the second guide plate 310 on the lower side of the discharge port 101 is opposite), and the sliding plate 340 drives the second guide plate 310 to move in the X direction. As the hard box moves inward, the contact area between the second guide plate 310 and the hard box becomes larger and larger, so the hard box is smoothly docked with the discharge port 101.

[0042] The present invention also provides a baler 10 , the side discharge port 101 of the baler 10 is provided with the above-mentioned discharge port docking device 20 , and the tobacco leaves packaged by the baler 10 are output from the discharge port 101 and enter into a hard box, and the hard box and the discharge port 101 are docked through the discharge port docking device 20 .

[0043] The discharge port docking device 20 and the baler 10 provided by the present invention can achieve accurate docking of the hard box with the discharge port 101 by using the first stopper assembly 200 and the second stopper assembly 300, and have a simple structure and are easy to operate. Furthermore, by using the stopper portion 212 of the first stopper assembly 200, the stability of the docking between the hard box and the discharge port 101 is achieved, thereby improving the packaging efficiency of the baler 10.

[0044] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
