Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a novel bamboo chip feeding mechanism. Background Art

[0002] Most of the existing fine planer feeding mechanisms are too inefficient, and can only feed about 20 bamboo strips per minute. In addition, there are situations where empty materials or multiple pieces enter the feeding trough. To solve the above problems, the feeding mechanisms currently on the market all adopt the method of accelerating the feeding speed so that the frequency of single-piece material can be roughly equal to the fine planing frequency of the fine planer, thereby meeting production needs. This method usually requires adding signals to monitor empty materials and multiple materials, which undoubtedly increases equipment costs. Utility Model Content

Under the action of the pushing assembly, the bamboo pieces at the bottom of the feeding channel enter the feeding channel, and the bamboo pieces in the feeding channel are arranged side by side. The pushing assembly pushes the bamboo pieces in the feeding channel outward, and cooperates with the conveying assembly to feed the outermost bamboo pieces into the fine planer. When the outermost bamboo piece has not yet completely entered the fine planer, the next bamboo piece has been pushed out and contacts the side of the previous bamboo piece. When the end of the current bamboo piece exceeds the front end of the next bamboo piece, the side end of the second bamboo piece contacts the conveying assembly again due to the thrust of the pushing assembly, driving the bamboo strips forward. This feeding method can realize the bamboo pieces entering the fine planer end to end, greatly improving production efficiency.

[0030] 2. Since the air pressure of the second cylinder is low, when it touches the bamboo piece and the bamboo piece touches the roller, the second cylinder acts as a buffer to prevent the friction between the bamboo piece and the roller from driving the bamboo piece into the planer. In addition, the second cylinder can also adapt to bamboo strips of different widths. When the bamboo strips are wider, the bamboo strips touch the roller before the narrow bamboo strips. After the touch, due to the high air pressure of the first cylinder, the second cylinder will retreat and adjust to the state of pressing the bamboo strips but will not lock the bamboo strips and make them unable to move. When the bamboo strips are narrow, after the first cylinder reaches the movement stroke, the second cylinder will continue to move forward and gradually push the bamboo strips to gradually touch the roller. When a piece of bamboo strips in contact with the roller moves forward and enters the planer, the cylinder can retreat for the next push, thereby meeting the orderly movement of bamboo strips of different widths.

[0051] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0052] Please refer to Figures 1 to 6 The utility model provides a feeding mechanism of a bamboo chip planer 8, comprising a frame 1, a baffle 5, a hopper 2, a pushing assembly 3 and a conveying assembly 4;

[0053] There are two groups of silos 2, which are respectively arranged on the surface of the frame 1 near both ends. The silos 2 include a left material plate 21, a right material plate 22 and a blanking plate 23.

[0054] The left material plate 21 and the right material plate 22 are arranged opposite to each other, and a vertical material discharge channel is formed between the left material plate 21 and the right material plate 22;

[0055] The blanking plate 23 is arranged below the left material plate 21 and the right material plate 22, and a feeding channel is formed between the blanking plate 23 and the left material plate 21. The feeding channel only allows a single piece of bamboo to pass along the length direction of the feeding channel, and the feeding channel can accommodate at least two pieces of bamboo side by side. One end of the feeding channel is connected to the blanking channel, forming an L-shaped channel with the blanking channel.

[0056] The conveying assembly 4 is arranged on the frame 1 at the opening of the feeding channel of the silo 2 at one end of the fine planer 8, and is used to convey the first bamboo piece at the opening of the feeding channel toward the fine planer 8;

[0057] The baffle 5 is fixed on the frame 1 and is used to block the second bamboo piece in the feeding channel from being transported toward the fine planer 8;

[0058] The pushing assembly 3 is installed on the frame 1 and is used to push the bamboo chips in the discharge channel toward the feeding channel;

[0059] When in use, the bamboo strips are stacked and placed in the feeding channel. Under the action of the pushing component 3, the bamboo strips at the bottom of the feeding channel enter the feeding channel, and the bamboo strips in the feeding channel are arranged side by side. The pushing component 3 pushes the bamboo strips in the feeding channel outward, and cooperates with the conveying component 4 to send the outermost bamboo strips into the fine planer 8. When the outermost bamboo strip has not completely entered the fine planer 8, the next bamboo strip has been pushed out and contacts the side of the previous bamboo strip. After the end of the current bamboo strip exceeds the front end of the next bamboo strip, due to the thrust of the pushing component 3, the side end of the second bamboo strip contacts the conveying component 4 again to drive the bamboo strips forward. This feeding method can realize the bamboo strips entering the fine planer 8 in a head-to-tail manner, which greatly improves production efficiency.

[0060] In this embodiment, the pusher assembly 3 includes a guide rail 31, a first cylinder 34, a second cylinder 35, a first slider 32, a second slider 33 and a pusher plate 36;

[0061] The guide rail 31 is fixed on the frame 1;

[0062] The first slider 32 and the second slider 33 are both slidably mounted on the guide rail 31;

[0063] The first cylinder 34 is mounted on the guide rail 31 , and the piston rod of the first cylinder 34 is connected to the first slider 32 ;

[0064] The second cylinder 35 is a low-pressure cylinder. The second cylinder 35 is mounted on the first slider 32 , and the piston rod of the second cylinder 35 is connected to the second slider 33 .

[0065] The push plate 36 is installed on the surface of the second slider 33;

[0066] The air pressure of the second cylinder 35 is lower than that of the first cylinder 34. Due to the low air pressure of the second cylinder 35, when it touches the bamboo piece and the bamboo piece contacts the roller 41, the second cylinder 35 plays a buffering role, thereby preventing the friction between the bamboo piece and the roller 41 from being able to drive the bamboo piece into the fine planer 8. In addition, the second cylinder 35 can also adapt to bamboo strips of different widths. When the bamboo strips are wider, the bamboo strips touch the roller 41 before the narrow bamboo strips. At this time, after touching, due to the high air pressure of the first cylinder 34, the second cylinder 35 will retreat and adjust to the state of pressing the bamboo strips but will not lock the bamboo strips and cannot move. When the bamboo strips are narrow, after the first cylinder 34 reaches the movement stroke, the second cylinder 35 will continue to move forward and gradually push the bamboo strips to gradually touch the roller 41. When a piece of bamboo strips in contact with the roller 41 moves forward and enters the fine planer 8, the cylinder can retreat for the next push, thereby meeting the orderly movement of bamboo strips of different widths.

[0067] In this embodiment, the height of the plane on which the upper surface of the pushing plate 36 is located is 2-4 mm higher than the height of the plane on which the upper surface of the blanking plate 23 is located, which enables the pushing plate 36 to effectively push the bamboo slices at the bottom of the feeding channel. In addition, since the pushing plate 36 is 2-4 mm higher, after the pushing plate 36 pushes out the bottom bamboo slice, the remaining bamboo slices in the hopper 2 are raised as a whole by 2-4 mm under the support of the pushing plate 36, further preventing the second-to-last bamboo slice from being brought out of the hopper 2. After the pushing plate 36 retracts, the bamboo slices in the hopper 2 fall as a whole and return to their original positions.

[0068] In this embodiment, the conveying assembly 4 includes a motor 45, a reducer 44, a bearing seat 43, a rotating shaft 42 and a roller 41;

[0069] The bearing seat 43 is mounted on the frame 1;

[0070] The rotating shaft 42 is installed in the bearing seat 43, and the top end of the rotating shaft 42 is connected to the roller 41, and the bottom end of the rotating shaft 42 is connected to the reducer 44 and the motor 45 in sequence; when in use, the motor 45 drives the rotating shaft 42 to rotate through the reducer 44, and the rotating shaft 42 drives the roller 41 to rotate. The bamboo pieces in contact with the roller 41 cooperate with the thrust of the pushing assembly 3, thereby driving the bamboo pieces to move forward.

[0071] In this embodiment, an optical axis 6 is also included. The optical axis 6 is arranged at the opening of the material feeding channel of the hopper 2 on the frame 1 away from the end of the fine planer 8. The rear end of the bamboo strip is limited by the optical axis 6. When the front and rear ends of the bamboo strip are simultaneously thrust by the cylinder and contact the roller 41, the bamboo strip cannot move forward to enter the fine planer 8. After many tests, it was found that the bamboo strip can smoothly enter the fine planer 8 without the roller 41 at the rear end.

[0072] In this embodiment, the left material plate 21 is connected to the height adjustment component 9, and the height adjustment component 9 includes an adjustment rail 91 and an adjustment slider 92. The adjustment rail 91 is vertically arranged, and the adjustment slider 92 is slidably installed on the adjustment rail 91 and fixed by bolt fasteners. The left material plate 21 is fixedly installed on the adjustment slider 92. By adjusting the height of the left material plate 21, bamboo pieces of different thicknesses can enter the feeding channel.

[0073] In this embodiment, an L-shaped supporting plate 7 is further included. The L-shaped supporting plate 7 is arranged on the frame 1 and located between the two groups of silos 2 to prevent the tail of the bamboo strips from swinging or sagging when entering the fine planer 8.

[0074] The working principle of this utility model is as follows:

[0075] The bamboo strips are stacked and placed in the feeding channel. Under the action of the pushing component 3, the bamboo strips at the bottom of the feeding channel enter the feeding channel, and the bamboo strips in the feeding channel are arranged side by side. The pushing component 3 pushes the bamboo strips in the feeding channel outward, and cooperates with the conveying component 4 to send the outermost bamboo strips into the fine planer 8. When the outermost bamboo strip has not completely entered the fine planer 8, the next bamboo strip has been pushed out and contacts the side of the previous bamboo strip. After the end of the current bamboo strip exceeds the front end of the next bamboo strip, the side end of the second bamboo strip contacts the conveying component 4 again due to the thrust of the pushing component 3, driving the bamboo strips forward. This feeding method can realize the bamboo strips entering the fine planer 8 in a head-to-tail manner, which greatly improves production efficiency.
