[0045] As shown in the drawings, Figure 3 In the material collecting state, the cylinder piston rod extends upwards, drives the sliding block fixing seat 10, the funnel 2 and the guide groove plate 11 to move upwards, the cam 13 moves into the hook segment of the guide groove 12, the one end of the swing rod 14 hinged with the pull rod 15 is raised, and the pull rod 15 drives the hopper opening and closing mechanism 5 to close.

[0046] As shown in the drawings, Figure 4 In the material discharging state, the cylinder piston rod is retracted downwards, drives the sliding block fixing seat 10, the funnel 2 and the guide groove plate 11 to move downwards, the funnel 2 is lowered into the packaging bag, at this time, the cam 13 moves into the linear segment of the guide groove 12, the raised one end of the swing rod 14 is restored, and the pull rod 15 drives the hopper opening and closing mechanism 5 to open.

[0047] The material discharging device of the application further reduces the material falling distance by lowering the funnel 2 into the packaging bag during discharging, thereby reducing the waiting time of other stations and improving the production speed of the packaging machine.

[0048] When packaging bulk materials (especially when the length of the material is greater than the opening diameter of the bag), the cylinder piston rod can quickly and reciprocally move in a small range, drives the sliding block fixing seat 10, the funnel 2 and the guide groove plate 11 to vibrate upwards and downwards, at this time, the cam 13 always moves in the linear segment of the guide groove 12, ensures that the lower discharge port 4 of the buffer hopper is always closed, and the material in the funnel 2 is vibrated to avoid the material blocking phenomenon.

[0049] In further specific embodiments, as shown in the drawings, Figures 9-11As shown, the hopper opening and closing mechanism 5 comprises an opening and closing mechanism support 16 fixed to the buffer hopper 1 near the side of the mounting plate 3, and an opening and closing mechanism shell 17 fixed inside the opening and closing mechanism support 16, and the pull rod 15 extends into the opening and closing mechanism shell 17, and the opening and closing mechanism shell 17 is internally provided with a pull rod moving groove 18 for the up and down movement of the pull rod 15; the top end of the pull rod 15 is hingedly connected to one end of a hinge plate 19 arranged inside the opening and closing mechanism shell 17, the other end of the hinge plate 19 extends out of the opening and closing mechanism shell 17 and is hingedly connected to the middle section of a swing block 20, and the swing block 20 is provided with a hopper door plate 21 matched with the lower discharge port 4 of the buffer hopper 1 on the upper surface near the side of the buffer hopper 1, and the end of the swing block 20 away from the buffer hopper 1 is hingedly connected to the opening and closing mechanism support 16 through a rotating shaft 22.

[0050] In the present application, the pull rod 15 is a vertical inclined rod, and the pull rod 15 moves obliquely downward to drive the hinge plate 19 to move obliquely downward and pull the swing block 20 and the hopper door plate 21 to rotate along the rotating shaft 22 to open the hopper door plate 21 blocking the lower discharge port 4 of the buffer hopper. Conversely, the pull rod 15 moves obliquely upward to drive the hinge plate 19 to move obliquely upward and pull the swing block 20 and the hopper door plate 21 to rotate along the rotating shaft 22 to drive the hopper door plate 21 to block the lower discharge port 4 of the buffer hopper again.

[0051] In a further specific embodiment, the middle section of the hinge plate 19 is fixedly connected with a spring, and the upper end of the spring is fixedly connected with the opening and closing mechanism support 16, so that the spring can provide a rebound force to the hinge plate 19 when the hinge plate 19 moves obliquely upward, to ensure that the hopper door plate 21 can tightly block the lower discharge port 4 of the buffer hopper.

[0052] Further, as shown in Figure 3 , 4 the lower discharge port 4 of the buffer hopper is a beveled port, so that the hopper door plate 21 only needs to rotate an acute angle to open the lower discharge port 4 of the buffer hopper, so that the pull rod 15 does not need to move a long distance.

[0053] In a further specific embodiment, as shown in Figure 5 in order to ensure stable sliding of the sliding block fixing seat 10, two groups of guide rails 8 are oppositely arranged in the guide rail device 6, and the two sliding blocks 9 matched with the guide rails 8 are fixedly installed on the two sides of the sliding block fixing seat 10.

[0054] In a further specific embodiment, as shown in Figure 6 the sliding block fixing seat 10 is provided with an opening hole 23 for fixedly connecting the piston rod of the air cylinder and a sunken groove 24 for installing the guide groove plate 11.

[0055] In the present application, the funnel 2 and the corresponding side end of the sliding block fixing seat 10 extending out of the guide rail device 6 are detachably connected, and specifically, as shown in Figures 12-13As shown, the funnel connecting section 25 is integrally formed on one end of the sliding block fixing seat 10 close to the funnel 2, and vertical bolt holes 26 are formed on the funnel connecting section 25; the funnel welding handle 27 is fixedly connected to the side wall of the funnel 2, can be fitted and installed on the funnel connecting section 25, and a U-shaped opening 28 is formed on the upper plate surface of the side of the funnel welding handle 27 close to the funnel connecting section 25; the bolt one 29 passes through the U-shaped opening 28 from top to bottom and is screwed into the bolt hole 26, thereby locking the funnel welding handle 27 on the funnel connecting section 25.

[0056] Further, two parallel installation grooves 30 are formed on the side of the funnel connecting section 25 close to the funnel 2, a positioning block 31 is installed in cooperation with the funnel connecting section 25 through the two installation grooves 30, a positioning bolt hole one 32 is formed on the positioning block 31, a positioning bolt hole two 33 is formed on the funnel welding handle 27, and the hole diameter of the positioning bolt hole two 33 is greater than that of the positioning bolt hole one 32; the bolt two 34 passes through the positioning bolt hole two 33 and the positioning bolt hole one 32 from top to bottom in sequence, thereby locking the funnel welding handle 27 and the positioning block 31.

[0057] At the same time, the inner top surface of the funnel welding handle 27 is provided with a buffer pad 35 between the top surface of the positioning block 31 and the funnel connecting section 25.

[0058] Working principle of the present application:

[0059] At the beginning, the funnel opening and closing mechanism 5 is in a closed state, and the material falls into the buffer hopper 1 to collect the material. When the material needs to be discharged, the lifting cylinder 7 drives the funnel 2 to bag (i.e. the funnel 2 is lowered into the inside of the packaging bag), and at the same time, the cam 13 moves in the guide groove 12, thereby opening the funnel opening and closing mechanism 5 to discharge the material.

[0060] When producing large-volume materials (especially when the length of the material is greater than the opening diameter of the bag), the lifting cylinder 7 will quickly reciprocate in a small range during the discharging process, thereby driving the funnel 2 to vibrate to avoid the situation of material blockage. During the vibration process, since the cam 13 is in the straight section of the guide groove 12, the vibration of the funnel 2 will not affect the opening and closing of the funnel opening and closing mechanism 5.

[0061] When the funnel 2 needs to be replaced, the funnel 2 can be disassembled by loosening the bolt one 29 (only needs to be loosened, without disassembly), thereby saving time. The positioning block 31 below the funnel 2 is in a stop opening cooperation with the sliding block fixing seat 10, a large circular hole (the positioning bolt hole two 33) is formed on the funnel welding handle 27, and the positioning block 31 can move in any direction (within 3mm) relative to the funnel welding handle 27. After the funnel 2 is adjusted to the appropriate position, the bolt two 34 is tightened, and the position of the positioning block 31 is fixed, thereby realizing that the funnel 2 does not need to be repositioned after replacement, and avoiding the phenomenon of repositioning after replacement due to the machining error of each funnel 2.

[0062] Overall, the application improves the feeding speed of the packaging machine through the integrated linkage (one power drive) of the buffer and vibration functions, avoids the jamming of large-volume materials (such as cheese sticks), and uses one cylinder to realize the lifting and opening and closing functions, reduces the power source input, effectively reduces the maintenance cost of the mechanism in the later period, and can be suitable for various materials and bag types due to the replaceable lowermost funnel.

[0063] The various embodiments are described in the specification by way of progression, each building on the previous embodiment, but it is contemplated that one could implement or use the various embodiments individually or combine parts of the various embodiments.

[0064] The above description of disclosed embodiments enables a person skilled in the art to implement or use the application.
