[0004] However, the above-mentioned feeding device still has shortcomings. The tea leaves are directly poured from the hopper into the strip sorting machine without being dispersed in the hopper. This easily causes the tea leaves to be unevenly distributed in the strip sorting slot when pouring the tea leaves. Utility Model Content

[0005] The utility model aims to provide a feeding device for a tea stripping machine, which has the effect of improving the distribution uniformity of tea leaves in a stripping groove.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a feeding device for a tea stripping machine, comprising a frame, a stripping groove connected to the frame and a hopper slidably connected to the frame, the hopper slides close to or away from the stripping groove, an elastic bottom plate and a toggle shaft located below the elastic bottom plate are provided at the bottom of the hopper, a plurality of toggle cams are provided along the axial direction of the toggle shaft, the toggle cams rotate and contact the elastic bottom plate, a driving device for driving the hopper to approach or move away from the stripping groove and a vibration device for driving the toggle shaft to rotate are provided on the frame.

[0007] By adopting the above technical solution, a hopper is used to hold tea leaves, and a toggle shaft with multiple toggle cams is arranged under the hopper. The rotation of the toggle shaft drives the multiple toggle cams to collide with the elastic bottom plate located under the hopper respectively, thereby driving the elastic bottom plate to vibrate, thereby evenly distributing the tea leaves in the hopper, so that the tea leaves are more evenly distributed after being poured into the strip sorting groove.

[0008] The utility model is further configured as follows: two support frames are slidably connected to the frame body and are respectively located on both sides of the hopper; the hopper is rotatably connected to the support frames; a limit plate is provided on the support frames to limit the bottom of the hopper from rotating close to the strip sorting groove; when the hopper contacts the limit plate, the elastic bottom plate is located directly above the toggle shaft; a push rod is provided between the hopper and the strip sorting groove; the hopper is subjected to the thrust of the push rod so that the hopper rotates and tilts above the strip sorting groove.

[0009] By adopting the above technical solution, the support frame and the hopper are close to the strip sorting groove together. When the hopper contacts the pushing rod, the hopper continues to approach the strip sorting groove, so that the pushing rod pushes the hopper to rotate to dump the tea leaves in the hopper toward the top of the strip sorting groove. When the hopper is away from the strip sorting groove, the hopper is reset, and the limit plate limits the continued deflection of the hopper.

[0010] The utility model is further configured as follows: a pulling spring is connected between the hopper and the support frame, and the pulling spring pulls the hopper to rotate and fit with the limit plate.

[0011] By adopting the above technical solution, when the hopper is away from the strip sorting groove, the hopper is reset, and the pulling spring pulls the hopper to rotate and fit with the limit plate, thereby improving the stability of the hopper during movement.

[0012] The utility model is further configured as follows: the vibration device comprises a driving motor fixedly connected to the support frame, and the driving motor is fixedly connected to the toggle shaft to drive the toggle shaft to rotate.

[0013] The utility model is further configured as follows: the driving device comprises a transmission gear fixedly connected to the end of the shifting shaft and a transmission rack fixedly connected to the frame, and the transmission gear is meshed with the transmission rack.

[0014] By adopting the above technical solution, the driving motor drives the toggle shaft to rotate, and at the same time, the meshing of the transmission gear and the transmission rack is used to realize the reciprocating movement of the support frame together with the hopper on the frame body.

[0015] The utility model is further configured as follows: a material guide groove is fixedly connected to the push rod, and the material guide groove is inclined downward and points to the top of the strip sorting groove.

[0016] By adopting the above technical solution, the material guiding trough guides the tea leaves poured from the hopper, so that the tea leaves can slide stably into the tea sorting trough.

[0017] The utility model is further configured as follows: one end of the toggle cam in contact with the elastic bottom plate is rotatably connected to a rolling wheel.

[0018] By adopting the above technical solution, when the driving wheel and the elastic bottom plate move relative to each other, the rolling wheel converts the sliding friction between the driving cam and the elastic bottom plate into the rolling friction between the rolling wheel and the elastic bottom plate, thereby reducing the wear on the elastic bottom plate.

[0019] The utility model is further configured as follows: a connection port is provided on the bottom plate of the hopper, and connection grooves for inserting the elastic bottom plate are provided on both sides of the connection port.

[0020] By adopting the above technical solution, the elastic base plate is inserted from the end of the connecting groove to realize the connection of the elastic base plate.

[0021] The utility model is further configured as follows: a positioning screw for limiting the sliding movement of the elastic bottom plate in the connecting groove is threadedly connected to the end of the connecting groove.

[0022] By adopting the above technical solution, the positioning screw passes through the connecting groove and contacts the elastic bottom plate, thereby achieving the fixing of the elastic bottom plate in the connecting groove.

[0023] The utility model is further configured as follows: a pushing roller is rotatably connected to a side of the pushing rod close to the hopper.

[0024] By adopting the above technical solution, the contact and relative movement between the push rod and the hopper drive the push roller to rotate, thereby converting the sliding friction between the push rod and the hopper into the rolling friction between the roller rotation and the hopper, reducing the wear of the roller rotation and the hopper.

[0025] The beneficial effects of the utility model are:

[0026] 1. The rotation of the toggle shaft drives multiple toggle cams to collide with the elastic bottom plate under the hopper, thereby driving the elastic bottom plate to vibrate, thereby evenly distributing the tea leaves in the hopper, so that the tea leaves are more evenly distributed after being poured into the strip sorting groove;

[0027] 2. A transmission gear is arranged on the toggle shaft, and a transmission rack is arranged on the frame. When the driving motor drives the toggle shaft to rotate, the support frame and the hopper can move back and forth on the frame through the meshing of the transmission gear and the transmission rack.

DETAILED DESCRIPTION

[0033] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment, a feeding device for a tea stripping machine, such as Figure 1 , Figure 2As shown, it includes a frame 1, a strip sorting groove 2 connected to the frame 1, and a hopper 3 slidably connected to the frame 1. Two support frames 4 respectively located on both sides of the hopper 3 are slidably connected to the frame 1. The hopper 3 is rotatably connected to the support frames 4. An elastic bottom plate 31 and a toggle shaft 5 located below the elastic bottom plate 31 are provided at the bottom of the hopper 3. The toggle shaft 5 is provided with a plurality of toggle cams 51 along the circumferential direction. The toggle cam 51 rotates and contacts with the elastic bottom plate 31. One end of the toggle cam 51 in contact with the elastic bottom plate 31 is rotatably connected with a rolling wheel 52. When the rolling wheel and the elastic bottom plate 31 move relative to each other, the rolling wheel 52 converts the sliding friction between the toggle cam 51 and the elastic bottom plate 31 into the rolling friction between the rolling wheel 52 and the elastic bottom plate 31, thereby reducing the wear on the elastic bottom plate 31. The frame 1 is provided with a driving device for driving the hopper 3 to approach or move away from the strip sorting groove 2 and a vibration device for driving the toggle shaft 5 to rotate. The vibration device includes a driving motor 6 fixedly connected to the support frame 4. The driving motor 6 is fixedly connected to the toggle shaft 5 to drive the toggle shaft 5 to rotate. The driving device includes a transmission gear 7 fixedly connected to the end of the toggle shaft 5 and a transmission rack 11 fixedly connected to the frame 1. The transmission gear 7 is meshed with the transmission rack 11. The rotation of the driving motor 6 drives the toggle shaft 5 and the toggle cam 51 to rotate. Through the meshing of the transmission gear 7 and the transmission rack 11, the support frame 4 and the hopper 3 can reciprocate on the frame 1. The rotation of the toggle shaft 5 drives the multiple toggle cams 51 to collide with the elastic bottom plate 31 located below the hopper 3, respectively, thereby driving the elastic bottom plate 31 to vibrate, so that the tea leaves are evenly distributed in the hopper 3.

[0035] like Figure 1 , Figure 3 As shown, a limit plate 41 is provided on the support frame 4 to limit the bottom of the hopper 3 from rotating close to the strip sorting groove 2. A material blocking plate 35 is fixedly connected to the hopper 3. When the hopper 3 contacts the limit plate 41 through the material blocking plate 35, the elastic bottom plate 31 is located directly above the toggle shaft 5. A push rod 12 is provided between the hopper 3 and the strip sorting groove 2. The push rod 12 is rotatably connected to a push roller 13 on one side of the hopper 3. The hopper 3 is pushed by the push rod 12 so that the hopper 3 rotates and tilts above the strip sorting groove 2. A material guide groove 14 is fixedly connected to the push rod 12, and the material guide groove 14 is tilted downward and points above the strip sorting groove 2. A pulling spring 42 is connected between the hopper 3 and the support frame 4, and the pulling spring 42 pulls the hopper 3 to rotate and fit with the limit plate 41. The support frame 4 and the hopper 3 are close to the strip sorting groove 2. When the hopper 3 contacts the pushing rod 12, the hopper 3 continues to approach the strip sorting groove 2, so that the pushing rod 12 pushes the hopper 3 to rotate to dump the tea leaves in the hopper 3 toward the top of the strip sorting groove 2. When the hopper 3 leaves the strip sorting groove 2, the hopper 3 is reset, and the limit plate 41 limits the continued deflection of the hopper 3.

[0036] like Figure 2As shown, the bottom plate of the hopper 3 is provided with a connection port 32, and connection slots 33 for inserting the elastic bottom plate 31 are provided on both sides of the connection port 32. The ends of the connection slots 33 are threadedly connected with positioning screws 34 for limiting the elastic bottom plate 31 from sliding in the connection slots 33. The elastic bottom plate 31 is inserted from the ends of the connection slots 33 to achieve connection with the elastic bottom plate 31, and the positioning screws 34 pass through the connection slots 33 and contact the elastic bottom plate 31, thereby achieving the fixing of the elastic bottom plate 31 in the connection slots 33.

[0037] When the feeding device is used, the driving motor 6 drives the toggle shaft 5 to rotate so that the hopper 3 is close to or away from the strip sorting groove 2, and at the same time, the toggle cam 51 collides with the elastic bottom plate 31 located below the hopper 3, thereby driving the elastic bottom plate 31 to vibrate, thereby evenly distributing the tea leaves in the hopper 3. When the hopper 3 contacts the pushing rod 12, the hopper 3 continues to approach the strip sorting groove 2, so that the pushing rod 12 pushes the hopper 3 to rotate to dump the tea leaves in the hopper 3 onto the top of the strip sorting groove 2. When the hopper 3 is away from the strip sorting groove 2, the pulling spring 42 pulls the hopper 3 to rotate and fit with the limit plate 41 to achieve the resetting of the hopper 3.
