Description

Technical Field

[0001] The utility model relates to the technical field of bamboo processing equipment, in particular to a bamboo node removal mechanism. Background Art

[0002] When making some bamboo products, the bamboo nodes need to be removed, leaving only the bamboo tubes between the nodes. The traditional way of removing the bamboo nodes is to use a saw blade to saw off both sides of the bamboo node separately, which is a method with low working efficiency.

[0003] A Chinese patent application with publication number CN109366651A discloses a bamboo node removal device, which uses two parallel saw blades with a gap to simultaneously saw off both sides of a bamboo node, thereby improving work efficiency. However, the bamboo node removal device of the patent has the following defects: the bamboo node after sawing is easily stuck between the two saw blades, and the work needs to be stopped and the stuck bamboo node needs to be manually removed before the next sawing operation can be carried out, which offsets part of the work efficiency improvement advantage.

[0004] A Chinese patent with authorization announcement number CN220922734U discloses a bamboo segment removal device, which fixes a bamboo segment clamping and pushing piece on a frame so that the bamboo segment clamping and pushing piece is located between two saw blades. Since the bamboo segment clamping and pushing piece is relatively stationary with the frame, the bamboo segment cannot be prevented from being stuck between the two saw blades in time during the bamboo segment cutting process. Instead, the bamboo segment can only be pushed out by using the bamboo segment clamping and pushing piece when the two saw blades have completed cutting and have returned. In actual operation, the rotation speed of the two saw blades is extremely fast. When cutting the bamboo segment, the saw blade needs to wait until the saw blade has completely cut off the bamboo before returning. Since the saw blades rotate at a high speed, the bamboo tube stuck between the two saw blades may be thrown out at high speed under the centrifugal force of the saw blades before the saw blades return, which is not only easy to injure surrounding staff or damage surrounding equipment, but also easy to damage the saw blades.

[0005] Therefore, there is an urgent need to provide a bamboo joint removal mechanism that can avoid adverse consequences caused by the bamboo joint being stuck between two saw blades during the bamboo joint cutting process. Utility Model Content

Since the pushing piece is connected to the moving mechanism through a transmission mechanism with a telescopic piece, the moving mechanism will synchronously drive the pushing piece and the two saw blades to move, and can push the bamboo node out from between the two saw blades as soon as the bamboo node is cut off, thereby avoiding the bamboo node staying between the two saw blades for too long and being thrown out by the centrifugal force of the saw blades, thereby improving the safety of the equipment.

[0040] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0041] Please refer to Figures 1 to 3 The specific implementation of the utility model relates to a bamboo node removal mechanism, comprising:

[0042] Rack 1;

[0043] A sawing device 2, the sawing device 2 is connected to the frame 1, and the sawing device 2 comprises two saw blades 21 arranged in parallel and spaced apart from each other, and a first driving mechanism 22 for driving the two saw blades 21 to rotate;

[0044] A moving mechanism, the moving mechanism is connected between the frame 1 and the sawing device 2, and the moving mechanism is used to drive the sawing device 2 to move relative to the frame 1;

[0045] The pusher is located between the two saw blades 21 of the sawing device 2 . The pusher is connected to the moving mechanism via a transmission mechanism 5 , so that when the moving mechanism drives the sawing device 2 to move, the pusher is also driven to move. The transmission mechanism 5 includes a telescopic member 51 .

[0046] In the above implementation mode, refer to Figure 1, and also includes a conveying mechanism for limiting the conveying of the bamboo tube. The bamboo tube is conveyed axially from the conveying mechanism to the position where the bamboo node is exactly between the two saw blades 21. The moving mechanism is controlled to drive the sawing device 2 to move, so that the two saw blades 21 contact the two sides of the bamboo node and cut the bamboo node at one time. In the process of cutting the bamboo node, the pushing piece is always against the bamboo node under the drive of the transmission mechanism 5 with the telescopic member 51; when the two saw blades 21 completely cut off the bamboo node, the moving mechanism controls the sawing device 2 to retract, and the pushing piece pushes the bamboo node out between the two saw blades 21 under the action of the telescopic member 51.

[0047] In this embodiment, there is no specific limitation on the shape of the moving mechanism and the trajectory of driving the sawing device 2 to move. The sawing device 2 can be driven by a variety of moving mechanisms, and the moving trajectory can be a straight line movement along the guide rail, or an arc movement driven by the rocker arm 3.

[0048] As a preferred embodiment, the moving mechanism comprises:

[0049] A swing rod 3, wherein the swing rod 3 is pivotally connected to the frame 1 via a first pivot point 31, and the sawing device 2 is connected to the swing rod 3;

[0050] A second driving mechanism 6, wherein the second driving mechanism 6 is connected between the frame 1 and the swing rod 3 and is used to drive the swing rod 3 to swing;

[0051] The pusher is connected to the swing rod 3 via a transmission mechanism 5 .

[0052] In the above embodiment, the sawing device 2 is driven to swing with the first pivot point 31 as the center by driving the swing rod 3 to swing. In this structure, when driving the swing rod 3 to swing, a lever can be used, which is more labor-saving and efficient when driving compared to the method of moving the sawing device 2 along a straight line.

[0053] As a preferred embodiment, the pushing member is a pushing rod 4, one end of which is pivotally connected to the frame 1 via a second pivot point 41, and the other end is located between the two saw blades 21. The transmission mechanism 5 includes a telescopic rod, which is pivotally connected to the pushing rod 4 via a third pivot point 52, and the telescopic rod is pivotally connected to the rocker arm 3 via a fourth pivot point 53.

[0054] In the above structural design, when the swing rod 3 is driven to swing, the push rod 4 can be driven to move synchronously through the telescopic rod.

[0055] Preferably, the third pivot point 52 is located between the second pivot point 41 and the other end of the push rod 4 .

[0056] Preferably, the fourth pivot point 53 is located between the sawing device 2 and the first pivot point 31 .

[0057] In the design of the above structure, each pivot point is cleverly designed to make the mechanism more labor-saving during operation.

[0058] Preferably, the second driving mechanism 6 comprises:

[0059] A reduction motor 61, wherein the reduction motor 61 is connected to the frame 1;

[0060] A crank-connecting rod mechanism 62 , one end of which is connected to the output shaft of the reduction motor 61 , and the other end of which is pivotally connected to the rocker 3 via a fifth pivot point.

[0061] In the above structure, it is only necessary to control the reduction motor 61 to rotate in one direction, so that the crank connecting rod mechanism 62 can drive the swing rod 3 to swing back and forth, which is more labor-saving than the method of driving the sawing device 2 to move in a straight line in the prior art.

[0062] As a preferred embodiment, the first pivot point 31 is located between the sawing device 2 and the fifth pivot point. This structure utilizes a lever structure to make the driving of the swing rod 3 more labor-saving.

[0063] As a preferred embodiment, the pusher is a pusher rod 4, one end of which is pivotally connected to the frame 1 through a second pivot point 41, and the other end of which is located between the two saw blades 21;

[0064] The telescopic member 51 includes a screw rod 511, a first nut 512, a second nut 513, a pivot rod 514 and a spring 515;

[0065] One end of the screw rod 511 is pivotally connected to the push rod 4 through the third pivot point 52, and the pivot rod 514 is rotatably connected to the fourth pivot point 53 of the rocker arm 3 through a bearing. The pivot rod 514 is provided with a through hole 5141 arranged along its radial direction, and the screw rod 511 is movably inserted into the through hole 5141. The first nut 512 is screwed on the screw rod 511, and the first nut 512 is located between the third pivot point 52 and the through hole 5141. The second nut 513 is screwed on the screw rod 511, and the through hole 5141 is located between the first nut 512 and the second nut 513; the spring 515 is sleeved on the screw rod 511, and one end of the spring 515 abuts against the first nut 512, and the other end abuts against the pivot rod 514.

[0066] In the above implementation mode, refer to Figure 3The telescopic rod is composed of components such as a screw rod 511, a first nut 512, a second nut 513 and a spring 515. On the one hand, it has the advantage of being easy to install components such as the screw rod 511 and the spring 515. On the other hand, the effective length of the telescopic rod can be adjusted by adjusting the connection position of the first nut 512 and the second nut 513 on the screw rod 511, thereby facilitating fine-tuning the position of the push rod 4, thereby adjusting the position of the push rod 4 between the saw blades 21, and facilitating on-site debugging of the equipment.

[0067] As a preferred embodiment, the pusher is a push rod 4, one end of which is pivotally connected to the frame 1 via a second pivot point 41, and the other end is located between two saw blades 21. The push rod 4 is a bent rod bent in the sawing direction of the saw blade 21.

[0068] Since the surface of the bamboo tube is in the shape of an arc, the push rod 4 is designed as a bent rod structure, which can be in more stable contact with the bamboo node when it abuts against and pushes out the bamboo node, ensuring that when the saw blade 21 retracts, the pusher can promptly and stably push the bamboo node out from between the two saw blades 21, further improving safety.

[0069] As a preferred embodiment, the third pivot point 52 is located above the second pivot point 41. The design of the pivot point can further improve the stability of the mechanism transmission.
