Description

Technical Field

[0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a clamping and stabilizing mechanism and bamboo sawing equipment. Background Art

[0002] With the increasing demands for sawing quality and efficiency, mechanical clamping is now the most common method used for segmented bamboo cutting. Traditional clamping frames require adjusting the clamping opening to a size larger than the cross-sectional outer diameter of the bamboo to facilitate installation. Manual adjustment is then required to secure the bamboo to the clamping frame. While this method allows for secure clamping of the bamboo, it is labor-intensive and time-consuming. Therefore, rapidly clamping and unloading bamboo during the sawing process remains a key technical challenge.

[0003] Prior art, such as the Chinese invention patent with publication number CN114800699A, discloses a raw bamboo sawing device, which includes a workbench, a tip receiving platform for receiving the tip of the raw bamboo is provided on one side of the workbench, and a conveying device for conveying the raw bamboo is provided on the workbench and the tip receiving platform. The conveying device includes a conveying chain and a driving mechanism for driving the conveying chain to rotate, and a plurality of clamping mechanisms for fixing the raw bamboo are installed on the conveying chain. The workbench is provided with a plurality of sawing areas along the conveying direction of the raw bamboo, and a plurality of sawing machines are fixed in the sawing areas. Along the conveying direction of the raw bamboo, the projection of the sawing machine in the front sawing area of ​​two adjacent sawing areas on the rear sawing area is between the sawing machines on the rear sawing area. This invention uses a clamping mechanism to fix the raw bamboo on the conveyor chain to prevent the raw bamboo from moving during cutting, ensuring that the raw bamboo can be cut smoothly. At the same time, the sawing area is layered along the conveying direction of the raw bamboo to achieve staged cutting of the raw bamboo, reduce the impact of the raw bamboo bending on cutting, and improve the cutting quality of the raw bamboo.

[0004] Another example is a Chinese utility model patent with publication number CN217915809U, which discloses a clamping mechanism in a chain-driven bamboo segment clamping mechanism. The chain-driven bamboo segment clamping mechanism includes a chain and a clamping frame. The clamping frame includes a vertical rod and a horizontal rod. The horizontal rod is located above the chain. The top end of the vertical rod is fixedly connected to one end of the horizontal rod, and the bottom end of the vertical rod is mounted on the chain plate of the chain. A clamping space for clamping the bamboo segment is formed between the clamping frame and the chain. An opening is formed on one side of the clamping space for the bamboo segment to enter, and the direction of the opening is consistent with the transmission direction of the chain. This utility model patent achieves automatic clamping by installing the clamping frame on the chain. As the chain moves forward, the bamboo segment can enter through the opening of the clamping space. Two adjacent chain links can rotate relative to each other, so that the size of the clamping space formed by the clamping frame and the chain can change, thereby automatically adjusting to bamboo segments of different diameters and improving the applicability of the clamping frame to clamping bamboo segments.

[0005] The existing technology has the following problems: (1) The automatic clamping mechanism has limited clamping and fixing effect on bamboo with smaller diameters. The bamboo is prone to sliding and tilting during the sawing process, causing the saw blade to saw the bamboo at an angle or even damage the saw blade; (2) The clamping mechanism for firmly clamping the bamboo requires fine adjustment, which affects the realization of the automatic cycle of the sawing equipment. Summary of the Invention

[0006] The purpose of the present invention is to provide a clamping and stabilizing mechanism and a bamboo sawing device, which can firmly fix bamboos of different diameters during the sawing process, and can realize the automatic circulation of the sawing equipment without fine adjustment.

[0007] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is:

[0008] A clamping and stabilizing mechanism includes a frame, a chain carrier connected end to end and running reciprocatingly is provided on the frame, and a plurality of clamping components are provided on the chain carrier, and the clamping components include:

[0009] A fixed clamping member that maintains a constant relative position with the chain carrier;

[0010] A movable clamping member rotatably connected to the fixed clamping member, wherein the free end of the movable clamping member descends under the action of gravity and encloses the fixed clamping member and the chain carrier to form a clamping space adapted to the clamped member;

[0011] A rotation limiter provided between the fixed clamping member and the movable clamping member, the rotation limiter being used to enable the movable clamping member to rotate relative to the fixed clamping member only in the direction of movement of the chain carrier;

[0012] A material unloading auxiliary part is provided at the running end point of the chain carrier, and is used for temporarily releasing the restriction of the rotation limit part on the movable clamping part so that the clamped part can leave the clamping space.

[0013] The present invention comprises a fixed clamping member, a movable clamping member and a chain carrier, which together form a clamping space adapted to the clamped member. By controlling the movement direction of the free end of the movable clamping member, the movable clamping member cannot be reversed and can only move unidirectionally relative to the fixed clamping member toward the running direction of the chain carrier, thereby achieving clamping and fixing of clamped members of different diameters. At the same time, the unloading auxiliary member provided at the running end point of the chain carrier temporarily releases the free movement of the movable clamping member, breaking the restricted state of the clamping space. Combined with the position change of the chain carrier and the deadweight of the clamped member, the clamped member falls down by itself, completing the unloading of the clamped member.

[0014] By controlling the movement direction of the free end of the movable clamping part, it is ensured that the clamped parts of different diameters are firmly fixed and do not move, and the clamped parts can fall down by themselves during the blanking process. Without the need for fine adjustment, it saves time and effort and efficiently completes the firm clamping and release of clamped parts of different diameters.

[0015] In the above-mentioned clamping and stabilizing mechanism, one end of the fixed clamping member is detachably connected to the chain carrier, and the other end is provided with a connecting rod; the movable clamping member is rotatably connected to the connecting rod.

[0016] Since the movable clamping member and the fixed clamping member are axially connected via the connecting rod, the rotation limiting member controls the movement direction of the free end of the movable clamping member and thus controls the formation and opening of the clamping space.

[0017] The present invention controls the movement direction of the movable clamping member by switching the rotation limit member, thereby achieving stable clamping and release of the clamped member by the clamping assembly, thereby realizing the working cycle of the clamping and stabilizing mechanism.

[0018] In the above-mentioned clamping and stabilizing mechanism, the rotation limiting member includes:

[0019] A ratchet wheel connected to the movable clamping member, wherein the ratchet teeth on the outer periphery of the ratchet wheel are inclined toward a side opposite to the running direction of the chain carrier;

[0020] A pawl connected to a fixed clamp or connecting rod and interacting with the ratchet.

[0021] Furthermore, the pawl comprises a pawl body, which is detachably connected to the fixed clamp or the connecting rod via a shaft ring sleeved on the connecting rod; the pawl body is provided with a pawl portion that interacts with the ratchet.

[0022] The pawl body includes a short pawl portion that can interact with the ratchet and an open cavity with an open end. The disengagement of the short pawl portion from the ratchet is achieved by moving the tail hook away from the ratchet. The open cavity includes a first side wall with a longer length away from the ratchet and a second side wall with a shorter length close to the ratchet. The end of the first side wall is provided with a long pawl portion that interacts with the connecting rod and a movement gap between the pawl portion and the ratchet. The short pawl portion is formed at the end of the second side wall.

[0023] By setting an open cavity with an open end, a hollow structure is formed between the first side wall and the second side wall, so that the structure of the first side wall and the second side wall has a certain elasticity, so that the short claw portion can interact with or disengage from the ratchet; and the long claw portion that interacts with the connecting rod further ensures the stability of the ratchet rotation.

[0024] In the above-mentioned clamping and stabilizing mechanism, the tail end of the pawl body has a tail hook, the opening of which faces the chain carrier; the unloading auxiliary component includes an upper crossbar fixed to the frame, and the pawl has a clamping position in which the pawl is inserted into the ratchet gap to lock the ratchet wheel, and a unloading position in which the pawl is lifted by the upper crossbar to leave the ratchet gap and release the ratchet wheel;

[0025] The tail end of the claw portion is elastically connected to the pawl body, the head end of the claw portion extends toward the head end of the pawl body, and an escape space is left between the pawl body and the claw portion to facilitate elastic deformation of the claw portion.

[0026] The pawl at the pawl clamping position interacts with the ratchet, and the movable clamping part pushes the clamped part toward the fixed clamping part in an irreversible unidirectional movement on one side until it contacts the surface of the clamped part. After being blocked by the clamped part, the movable clamping part cannot continue to move forward. At this time, the clamped part, the movable clamping part, the fixed clamping part and the chain carrier form a stable dynamic balance, thereby the clamping assembly stably fixes the clamped part; during the unloading process, the pawl at the pawl unloading position disengages from the ratchet, and the movable clamping part rotates freely. The above-mentioned dynamic balance is broken, and the clamped part is able to fall to realize the unloading of the clamped part.

[0027] In the above-mentioned clamping and stabilizing mechanism, the frame is provided with an unlocking member on the rotating side of the chain carrier, which is used to temporarily release the restriction of the rotation limit member on the movable clamping member so that the free end of the movable clamping member drops under the action of gravity and thus opens the clamping space.

[0028] The fixed clamping member returns with the chain carrier, and the unlocking member releases the restriction of the rotation limit member on the movable clamping member, releasing the movable clamping member to move freely until the movable clamping member and the fixed clamping member form an angle of 180 degrees. The movable clamping member and the fixed clamping member forming the 180-degree angle and the return section together form the position where the clamped member is dialed in.

[0029] Furthermore, the unlocking member includes a lower cross bar fixed to the frame, and the pawl has a return position in which the pawl releases the ratchet due to the lower cross bar pressing down the tail hook so that the movable clamping member returns to its original position due to gravity.

[0030] The tail hook has an arc-shaped tail hook that interacts with the fixed blanking crossbar. When it touches the fixed blanking crossbar, the tail hook is lifted, which in turn drives the entire pawl, causing the short claw to separate from the ratchet, and the ratchet to resume free rotation. The lower crossbar interacts with the tail hook, exerting a force on the pawl to disengage the ratchet. The free movement of the ratchet is affected by the gravity of the movable clamping part. The movable clamping part and the fixed clamping part form a 180-degree angle, and the movable clamping part becomes straight. At this time, the pawl enters the recovery position, and the ratchet in the pawl clamping position can only move in one direction, thus forming the clamped part in the dial-in position, ready for dialing in the clamped part.

[0031] In the above-mentioned clamping and stabilizing mechanism, the tail hook has a guide portion that facilitates the upper cross bar or the lower cross bar to be inserted into or slid out.

[0032] The tail hook moves forward with the chain carrier until it connects with the auxiliary part, and the auxiliary part enters the guide part along the arc, driving the tail hook to move in the direction away from the ratchet, and the short claw part separates from the ratchet to form the ratchet lowering position; because the tail hook moves forward with the chain carrier, the auxiliary part leaves the guide part along the arc, and the tail hook moves in the direction close to the ratchet, the short claw part interacts with the ratchet again, and the ratchet enters the ratchet recovery position.

[0033] In the above-mentioned clamping and stabilizing mechanism, the movable clamping member has an anti-slip portion on a side facing the clamping space; or the movable clamping member is covered with an anti-slip sleeve;

[0034] The chain carrier comprises at least two parallel arranged ones, each clamping assembly comprises a fixed clamping piece corresponding to the chain carrier one by one, the fixed clamping pieces belonging to the same group are connected in series by a connecting rod, and at least one movable clamping piece is provided between adjacent fixed clamping pieces.

[0035] The movable clamping member is a counterweight block, which uses its own weight to limit the clamped member after contacting the clamped member. The counterweight block can be made of materials such as cast iron and lead.

[0036] By arranging corresponding movable clamping parts, rotation limiting parts and fixed clamping parts at both ends of a connecting rod, the clamping space of the clamping assembly of the clamping and stabilizing mechanism for sawing the clamped part is increased, and more resistance is provided for the stable clamping of the clamped part.

[0037] The movable clamping piece is provided with an anti-slip cover, and the surface of the anti-slip cover is provided with a plurality of anti-slip textures. The provision of the anti-slip cover prevents the anti-slip cover and the clamped piece from sliding after being stably connected, further improving the stability of the clamping mechanism.

[0038] Preferably, baffles are provided on both sides of the connecting rod to limit the axial movement of the movable clamping member.

[0039] A bamboo sawing device comprises a sawing mechanism for sawing a clamped piece, and a clamping and stabilizing mechanism for conveying the clamped piece to the sawing mechanism, wherein the clamping and stabilizing mechanism is the above-mentioned clamping and stabilizing mechanism;

[0040] There are at least two clamping and stabilizing mechanisms arranged in parallel.

[0041] The bamboo sawing equipment does not require human intervention, and can realize the clamping, unloading and loading of bamboos of different diameters, thereby realizing the automatic circulation of the bamboo sawing equipment.

[0042] Compared with the prior art, the beneficial effects of the present invention are embodied in:

[0043] (1) The present invention controls the movement direction of the free end of the movable clamping member, thereby ensuring that the clamped members of different diameters are firmly fixed and do not move, and also realizing that the clamped members fall down automatically during the blanking process. Without the need for fine adjustment, the present invention saves time and effort and efficiently completes the firm clamping and release of the clamped members of different diameters.

[0044] (2) The clamping assembly of the present invention controls the movement direction of the rotating limit member by switching the rotating guide member, thereby achieving the fixation, loosening and re-engagement of the clamped member to restore the working state of the clamped member, and the work of the clamping and stabilizing mechanism can be carried out in a cycle.

[0045] (3) The bamboo sawing equipment does not require manual intervention, and can clamp, unload and load bamboos of different diameters, thus realizing the automatic cycle of the bamboo sawing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Example 1

[0056] like Figure 2 and Figure 3 As shown, this embodiment provides a clamping and stabilizing mechanism 400, comprising a frame (not shown) on which is mounted a chain carrier 200 connected end to end and running in a reciprocating manner. In this embodiment, the chain carrier 200 is a chain. The chain carrier is provided with multiple clamping assemblies 100. A material unloading aid is provided at the end point of the chain carrier 200. In this embodiment, the material unloading aid is an upper crossbar 15 fixed to the frame. An unlocking member is provided on the rotating side of the chain carrier. In this embodiment, the unlocking member is a lower crossbar fixed to the frame.

[0057] The clamping assembly 100 includes a fixed clamping member 11, a movable clamping member 12, a rotation limiter 13, and a connecting rod 14. The connecting rod 14 is provided with corresponding fixed clamping members 11 at both ends. The movable clamping members 12 and the rotation limiter 13 are respectively sleeved on both ends of the connecting rod 14 and then connected to the fixed clamping member 11. The movable clamping member 12, the ratchet 132, the pawl 131, and the fixed clamping member 11 are all axially connected to the connecting rod 14. The movable clamping member 12 is axially connected to the top end of the fixed clamping member 11 through the mounting hole 122. Figure 4 As shown, baffles 141 are provided on both sides of the connecting rod 14 to limit the axial movement of the movable clamping member 12. The movable clamping member 12 is covered with an anti-slip sleeve 121. In this embodiment, the movable clamping member 12 is a counterweight. After contacting the clamped member 300, the counterweight uses its own weight to limit the position of the clamped member 300, i.e., the bamboo material. The counterweight can be made of materials such as cast iron and lead.

[0058] Combine Figure 7 As shown, the rotation limiting member 13 includes a pawl 131 and a ratchet 132 . The outer periphery of the ratchet 132 is provided with ratchet teeth 132 a inclined toward a side facing away from the running direction of the chain carrier 200 .

[0059] like Figure 5 and Figure 6As shown, the pawl 131 further includes a pawl body 133, which is detachably connected to the fixed clamp 11 via a connecting plate 134. The pawl body 133 is provided with a claw portion 135 that interacts with the ratchet 132. The tail end of the pawl body 133 has a tail hook 133a, the opening of which faces the chain carrier 200. The tail hook 133a is recessed inward to form an arc-shaped guide portion 133h that gradually curves toward the end of the tail hook 133a. The tail end of the claw portion 135 is elastically connected to the pawl body 133, and the head end of the claw portion 135 extends toward the head end of the pawl body 133. A clearance space is provided between the pawl body 133 and the claw portion 135 to facilitate elastic deformation of the claw portion 135. In this embodiment, the pawl body 133 is a curved hook-shaped structure with a cavity.

[0060] The pawl 131 has the following functions: the pawl portion 135 is inserted into the gap between the ratchet teeth 132a to lock the clamping position of the ratchet 132; the pawl portion 135 leaves the gap between the ratchet teeth 132a and releases the unloading position of the ratchet 132 due to the upper cross bar lifting the tail hook 133a; the pawl portion 135 is pressed down by the lower cross bar 16 to release the ratchet 132 so that the movable clamping member 12 descends due to gravity and returns to its original position.

[0061] Specifically, the pawl body 133 of the pawl 131 is positioned above the ratchet 132 and interacts with the ratchet 132. The pawl body 133 includes a short pawl portion 133e that interacts with the ratchet 132, an open cavity 133b with an open end, and a tail hook 133a. The open cavity 133b includes a first sidewall 133c that is longer away from the ratchet 132 and a second sidewall 133d that is shorter near the ratchet 132. The end of the first sidewall 133c is provided with a long pawl portion 133f that interacts with the connecting rod 14 and a clearance 133g between the pawl and the ratchet 132. The short pawl portion 133e is formed at the end of the second sidewall 133d. Disengagement of the short pawl portion 133e from the ratchet 132 is achieved by moving the tail hook 133a away from the ratchet 132. By setting an open cavity 133b with an end opening, a hollow structure is formed between the first side wall 133c and the second side wall 133d, so that the structure of the first side wall 133c and the second side wall 133d has a certain elasticity, so that the short claw portion 133e can interact with or disengage from the ratchet 132; and the long claw portion 133f that interacts with the connecting rod 14 further ensures the stability of the rotation of the ratchet 132. The pawl 131 enters the rotating side of the chain carrier 200 along with the chain carrier 200, and the tail hook 133a interacts with the unloading auxiliary part 15 to form the unloading position of the pawl 131: the tail hook 133a interacts with the upper cross bar 15, and when it touches the upper cross bar 15, the tail hook 133a is lifted, thereby driving the entire pawl 131, so that the short claw part 133e is separated from the ratchet 132, and the ratchet 132 resumes free rotation; after the pawl 131 is separated from the upper cross bar 15, the pawl 131 clamping position is formed again; the pawl 131 moves forward with the chain carrier 200, and the tail hook 133a interacts with the lower cross bar 16 to form the pawl 131 recovery position, the movable clamping part 12 rotates freely and forms an angle of 180 degrees with the fixed clamping part 11, and the pawl 131 is separated from the unloading auxiliary part 15 to form the pawl 131 clamping position again.

[0062] In this embodiment, during the sawing process, the fixed clamping member 11, the movable clamping member 12 and the chain carrier 200 jointly form a clamping position for the clamped member 300. Only by controlling the movement direction of the free end of the movable clamping member 12, it is impossible to reverse the direction and perform unidirectional rotation relative to the fixed clamping member toward the running direction of the chain carrier, thereby achieving clamping and fixing of bamboo segments of different diameters; at the same time, at the running end point of the chain carrier 200, that is, after the clamped member 300 completes sawing, the rotation limit member 13 releases the movable clamping member 12 for free movement, and the restricted state of the clamping position of the clamped member 300 is broken. Combined with the position change of the rotating side of the chain carrier 200 and the dead weight of the clamped member 300, the clamped member 300 falls down by itself, completing the unloading of the clamped member 300.

[0063] The working principle of this embodiment is as follows: the pawl 131 in the clamping position interacts with the ratchet 132, and the movable clamping member 12 cannot be reversed and pushes one side of the clamped member 300 toward the fixed clamping member 11 for unidirectional movement until it contacts the surface of the clamped member 300. After being blocked by the clamped member 300, the movable clamping member 12 cannot continue to move forward. At this time, the clamped member 300, the movable clamping member 12, the fixed clamping member 11 and the chain carrier 200 form a stable dynamic balance, thereby fixing the bamboo segment during the sawing process; during the cutting process, the pawl 131 in the released state disengages from the ratchet 132, and the movable clamping member 12 rotates freely. The aforementioned dynamic balance is broken, and the clamped member 300 is able to fall to realize the cutting of the clamped member 300. By controlling the movement direction of the movable clamping member 12, it is ensured that bamboo segments of different diameters are firmly fixed and do not move during the sawing process, and the clamped member 300 can fall down by itself during the cutting process. The entire sawing process does not require fine adjustment, and the clamped members 300 of different diameters are firmly clamped, fixed and released efficiently, saving time and effort.

[0064] Example 2

[0065] like Figure 1 and Figure 8 As shown, this embodiment provides a sawing device for a clamped part 300, including a sawing mechanism (not shown in the figure) for sawing bamboo materials, and a clamping and stabilizing mechanism 400 for conveying bamboo materials to the sawing mechanism, including a chain carrier 200 that reciprocates back and forth, and a plurality of clamping assemblies 100 are fixed on the chain carrier 200. In this embodiment, two clamping and stabilizing mechanisms 400 are arranged in parallel.

[0066] The working principle of this embodiment is as follows: Figure 7 As shown, the clamping assembly 100 is fixed on a reciprocating chain carrier 200 , which includes a chain carrier 200 , a rotating side of the chain carrier 200 and a chain carrier 200 . The fixed clamping member 11 is fixedly connected to the chain carrier 200 and moves with the chain carrier 200 .

[0067] ① Dial in bamboo materials: The rotating limiter 13 and the movable clamping member 12 dial in the bamboo materials from the feed port and are transmitted along with the chain carrier 200. The rotating limiter 13 restricts the movable clamping member 12 from reversing;

[0068] ②-③ Entering the sawing process: As the chain carrier 200 moves, the fixed clamping member 11 moves forward with the chain carrier 200, and the rotating limit member 13 controls the movable clamping member 12 to move unidirectionally clockwise. The movable clamping member 12 gradually presses the bamboo material and gradually presses the bamboo material downward under the action of gravity until it is completely in contact with the bamboo material. The fixed clamping member 11, the movable clamping member 12 and the chain carrier 200 together form a clamping space;

[0069] ④ Bamboo unloading: After the bamboo is sawn, the fixed clamping member 11 enters the rotating side of the chain carrier 200 with the chain carrier 200, the upper cross bar 15 toggles the tail hook 133a, the ratchet 131 is released, and the rotation limiter 13 releases the movable clamping member 12 to move freely and release the bamboo unloading. At this time, the bamboo is separated from the clamping mechanism under the action of its own weight.

[0070] ⑤~⑦ Bamboo material dialing in: In step ④, the lower cross bar 16 interacts with the tail hook 133a to give the pawl 131 a force to disengage the ratchet 132. The free movement of the ratchet 132 is affected by the gravity of the movable clamping member 12. The movable clamping member 12 and the fixed clamping member 11 form an angle of 180 degrees, and the movable clamping member 12 becomes straight. At this time, the pawl 131 enters the recovery position, and the pawl 131 controls the ratchet 132 to move in one direction, thereby forming the bamboo material dialing position, ready to dial in the bamboo material.

[0071] In this embodiment, by switching the rotation limiter 13 to control the movement direction of the free end of the movable clamping member 12, the clamping assembly 100 can fix, release and re-insert the bamboo material, thereby realizing the working cycle of the clamping assembly 100.

[0072] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
