Description

An elastic pressing assembly and pressing mechanism for sheet cutting and wire drawing Technical Field

[0001] This utility model relates to the field of bamboo processing technology, and more specifically, to an elastic pressing component and pressing mechanism for bamboo cutting and drawing. Background Technology

[0002] Bamboo and wood materials, due to their natural flexibility and elasticity, are prone to vibration during cutting, carving, and other processing, which can affect processing accuracy and finished product quality. To ensure the stability and precision of the processing, a pressure arm is usually used to limit the material's movement.

[0003] However, the connection structure between the pressing arm and the frame in existing shaving and drawing equipment generally involves multiple nested components such as a rotating sleeve and a drive shaft (e.g., the pressing arm is fitted onto the drive shaft via a rotating sleeve). This results in cumbersome assembly steps. If the fit tolerance between the drive shaft and the rotating sleeve is not properly controlled, jamming or loosening can easily occur, affecting the stability of the pressing arm. Simultaneously, the connection between the drive shaft and the rotating sleeve requires regular lubrication, but dust (such as debris from bamboo and wood processing) can easily penetrate the joint gaps, accelerating bearing wear and requiring frequent shutdowns for cleaning and component replacement, increasing maintenance costs. The sleeved structure relies on the rotation of the drive shaft to transmit power, but after long-term operation, the increased wear clearance can lead to a decrease in transmission rigidity, fluctuations in pressing pressure, and affect the uniformity of bamboo and wood shaving and drawing. Summary of the Invention

[0004] In view of this, the present invention provides an elastic pressing component and pressing mechanism for sheet cutting and wire drawing, which aims to solve the above-mentioned technical problems.

[0005] In one aspect, this utility model proposes an elastic pressing assembly for slitting and drawing wire, including a pressing arm connected to a frame via a rotating shaft, one end of the pressing arm being fixed to one end of the rotating shaft, and the rotating shaft and the frame being connected by an elastic structure, the elastic structure forcing the free end of the pressing arm to have a tendency to move toward the material side on the frame.

[0006] In some embodiments of this application, one end of the pressure arm is fixedly connected to one end of the rotating shaft by a plurality of fasteners.

[0007] In some embodiments of this application, the elastic structure includes a power arm fixedly disposed at the other end of the rotating shaft and an elastic member disposed between the frame and the power arm, and at least a portion of the power arm is slidably disposed on the elastic member.

[0008] In some embodiments of this application, there is an inclined angle between the power arm and the pressure arm.

[0009] In some embodiments of this application, the power arm has a Z-shaped structure.

[0010] In some embodiments of this application, the elastic member includes a connector disposed on the frame and an elastic element disposed on the connector.

[0011] In some embodiments of this application, the direction in which the connector is positioned is perpendicular to the direction in which the rotating shaft is positioned.

[0012] In some embodiments of this application, limiting portions are provided at both ends of the connector.

[0013] In some embodiments of this application, at least a portion of the power arm is slidably disposed between the two limiting portions on the connector, and one end of the elastic member is connected to at least a portion of the power arm slidably disposed on the connector, and the other end is connected to a limiting portion near the pressing arm.

[0014] Compared with existing technologies, the advantages of this invention are as follows: by fixing the pressing arm to one end of the rotating shaft, compared with the traditional technology of using a rotating sleeve to fit onto the rotating shaft, a direct fixing method is adopted, which simplifies the structure, reduces maintenance requirements, extends the service life of the equipment, and avoids the decrease in transmission rigidity caused by improper control of the fit tolerance between the transmission shaft and the rotating sleeve or wear at the connection between the transmission shaft and the rotating sleeve, thus affecting the uniformity of bamboo processing. In addition, this invention uses an elastic structure to force the free end of the pressing arm to move towards the material side of the frame, so that the thickness direction of the bamboo is clamped by the material side of the frame and the pressing arm, avoiding the impact of vibration on processing accuracy during the bamboo processing.

[0015] On the other hand, this utility model proposes a pressing mechanism, including an elastic pressing component for sheet cutting and wire drawing, and a limiting structure fixedly set on the frame. A material passage space is formed between the limiting structure and the elastic pressing component, and at least a portion of the pressing arm has an acute angle with the limiting plate.

[0016] It is understood that the pressing mechanism in this embodiment has the same beneficial effects as the elastic pressing component for sheet cutting and wire drawing, and will not be described in detail here. Attached Figure Description

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] Referring to Figures 1, 2, and 3, this embodiment provides a bamboo sheeting and drawing device, including a frame, a conveying mechanism formed by several conveying components 11 along the conveying direction, a width-fixing mechanism 1, a thickness-fixing mechanism 2, and a drawing and forming mechanism 3 arranged sequentially along the conveying direction on the frame, a pressing mechanism located at the width-fixing mechanism 1 and elastically pressing the sheet bamboo material conveyed by the conveying mechanism in the thickness direction on the frame, and a power assembly on the frame. The first part of the power assembly drives the conveying components 11 to move, the second part of the power assembly drives the first power shafts 8 included in the width-fixing mechanism 1, the thickness-fixing mechanism 2, and the drawing and forming mechanism 3 to rotate in a first rotation direction, and the third part of the power assembly drives the second power shafts 9 included in the thickness-fixing mechanism 2 and the drawing and forming mechanism 3 to rotate in a second rotation direction. The first part, the second part, and the third part are respectively mounted on a lifting and adjusting assembly 7.

[0035] It is understood that the bamboo slicing and drawing equipment in this embodiment is mainly used for processing bamboo products, precisely controlling the width, thickness, and shape of the bamboo material to improve production efficiency and product quality. The slicing and drawing equipment is supported by a frame and connected to other mechanisms to ensure stable operation. The conveying mechanism consists of several conveying components 11 forming along the conveying direction, responsible for conveying the sheet bamboo material from one process to the next. The width-fixing mechanism 1 is used to adjust the width of the bamboo material to achieve the required size. The thickness-fixing mechanism 2 is used to adjust the thickness of the sheet bamboo material to ensure the consistency of the finished product. The drawing and forming mechanism 3 shapes the sheet bamboo material into the required fine filament shape. The power system consists of three parts, driving the first power shaft 8 of the conveying components 11, the width-fixing and thickness-fixing mechanisms 2, and the second power shaft 9 of the thickness-fixing and drawing and forming mechanism 3. These power components are all mounted on the lifting and adjusting assembly 7 for easy adjustment and maintenance.

[0036] Understandably, in this embodiment, the width-fixing mechanism 1 achieves width-fixing by cutting away excess waste material from both sides of the bamboo sheet. During the width-fixing process, the cutting operation applies pressure to the thickness direction of the bamboo sheet. Since the bamboo sheet is a flexible material, it vibrates under pressure, reducing the accuracy of the width-fixing process. This embodiment addresses this by incorporating a pressing mechanism at the width-fixing mechanism 1, which compresses the bamboo sheet in the thickness direction, preventing positional shifts due to vibration during the width-fixing process, thus improving the accuracy and production efficiency.

[0037] Specifically, in this embodiment, the frame of the bamboo slicing and drawing equipment is also equipped with a dust baffle 13 to prevent bamboo waste from splashing during the processing.

[0038] Referring to Figures 10 and 11, in one specific embodiment of this application, the pressing mechanism includes an elastic pressing component and a limiting structure disposed on the frame, and a material passage space for sheet bamboo material to pass through is formed between the elastic pressing component and the limiting plate 51 of the limiting structure.

[0039] Understandably, in this embodiment, the pressing mechanism achieves precise positioning and fixation of the sheet bamboo material by combining an elastic pressing component and a limiting structure. The elastic pressing component applies appropriate force to press the sheet bamboo material firmly within the material passage space, ensuring that the sheet bamboo material does not move or slide during processing. The limiting structure controls the position and range of motion of the sheet bamboo material, preventing it from exceeding the material passage space. The elastic pressing component provides the necessary pressure, while the limiting structure ensures the correct position and range of motion of the sheet bamboo material, which not only improves processing accuracy but also reduces material waste and the defect rate.

[0040] In one specific embodiment of this application, the elastic pressing assembly includes a pressing arm 42 connected to the frame via a rotating shaft 41. One end of the pressing arm 42 is fixed to one end of the rotating shaft 41, and the rotating shaft 41 and the frame are connected by an elastic structure. The elastic structure forces the free end 421 of the pressing arm 42 to abut against the sheet bamboo material passing through the material passage space, and at least a portion of the pressing arm 42 has an acute angle with the limiting plate 51.

[0041] Furthermore, in this embodiment, the portion of the pressing arm 42 with the inclined surface 423 has an acute angle with the limiting plate 51, and the free end 421 of the pressing arm 42 has a detour portion 422. The detour portion 422 and the inclined surface 423 form acute angles in opposite directions with the limiting plate 51, and the inclined surface 423 and the detour portion 422 of the pressing arm 42 are in point contact with the limiting plate 51.

[0042] It is understood that in this embodiment, the rotating shaft 41 is connected to the frame, and one end of the pressing arm 42 is fixed to one end of the rotating shaft 41. The movement of the pressing arm 42 is achieved by rotating the rotating shaft 41. Traditional pressing assemblies usually adopt a sleeve structure, but during long-term use, wear can easily lead to a decrease in transmission rigidity. The direct fixing method in this embodiment avoids the decrease in transmission rigidity caused by wear during movement in traditional sleeve structures, which affects the uniformity of the width of the sheet bamboo.

[0043] Understandably, in this embodiment, the elastic structure connects the rotating shaft 41 and the frame. The elastic structure forces the free end 421 of the pressing arm 42 to move towards the material side of the frame, causing the free end 421 of the pressing arm 42 to abut against the sheet bamboo passing through the material passage space, maintaining pressure on the sheet bamboo in the thickness direction and ensuring the stability of the sheet bamboo during processing. An acute angle exists between the inclined surface 423 of the pressing arm 42 and the limiting plate 51, so that when no sheet bamboo enters the material passage space, the pressing arm 42 and the limiting plate 51 form point contact. A portion of the material passing through the space between the inclined surface 423 and the limiting plate 51 forms a triangle. When the sheet bamboo is conveyed into the material passage space, the sheet bamboo is restricted by the triangular material passage space and moves upwards towards the limiting plate 51, improving the pressing effect. Simultaneously, the point contact formed between the pressing arm 42 and the limiting plate 51 when no sheet bamboo enters optimizes the contact method, reduces friction and wear, and improves transmission rigidity.

[0044] Specifically, in this embodiment, one end of the pressure arm 42 is fixedly connected to one end of the rotating shaft 41 by a plurality of fasteners 10. The fasteners 10 are preferably bolts, but any component that can achieve fastening can be selected, and this embodiment does not make a specific limitation.

[0045] Specifically, in this embodiment, the elastic structure includes a power arm 43 fixedly disposed at the other end of the rotating shaft 41 and an elastic member disposed between the frame and the power arm 43, and at least a portion of the power arm 43 is slidably disposed on the elastic member.

[0046] It is understood that in this embodiment, one end of the rotating shaft 41 is fixedly provided with a power arm 43, and the other end is fixedly connected to a pressing arm 42. At least part of the power arm 43 is slidably disposed on the elastic member, allowing the power arm 43 to adjust the contact point with the elastic member during the movement. The torque is transmitted and amplified by the rotation of the rotating shaft 41 driven by the sliding of the power arm 43 on the elastic member, so that the free end 421 of the pressing arm 42 abuts against the sheet bamboo material passing through the material passage space.

[0047] Specifically, in this embodiment, the elastic component includes a connector 44 disposed on the frame and an elastic component 45 disposed on the connector 44.

[0048] Specifically, in this embodiment, the connector 44 has limiting portions 441 at both ends. At least a portion of the power arm 43 is slidably disposed between the two limiting portions 441 on the connector 44, and one end of the elastic member 45 is connected to at least a portion of the power arm 43 slidably disposed on the connector 44, and the other end is connected to a limiting portion 441 near the pressing arm 42. The connecting member 44 is positioned perpendicular to the direction of the rotating shaft 41.

[0049] Understandably, in this embodiment, the other end of the power arm 43, which is fixedly connected to the rotating shaft 41, is slidably disposed between the two limiting portions 441 of the connecting member 44. The two limiting portions 441 limit the travel range of the power arm 43. At the same time, the elastic member 45 is disposed between at least the portion where the power arm 43 is slidably connected to the connecting member 44 and a limiting portion 441 near the pressing arm 42. The restoring force generated by the elastic member 45 ensures that the power arm 43 drives the pressing arm 42 to keep the sheet bamboo material in the space pressed firmly.

[0050] Specifically, in this embodiment, there is an inclined angle between the power arm 43 and the pressure arm 42. The power arm 43 has a Z-shaped structure.

[0051] It is understandable that the Z-shaped structure of the power arm 43 and the angle design between it and the pressure arm 42 in this embodiment optimize the power transmission path and improve transmission efficiency.

[0052] Specifically, the limiting structure also includes two limiting members 52 that are movably connected to the frame. A limiting width adjusting member 6255 is provided on the frame that is at least partially inserted between the two limiting members 52. The two limiting members 52 tend to move towards each other through an elastic pressure member 57.

[0053] Specifically, according to the conveying direction, the front end of the limiting plate 51 passes through the two limiting members 52 and is fixed to the frame. The rear end of the limiting plate 51 is fixed to the frame through the fine-tuning structure 53 and two limiting guide blocks 54 are provided at the rear end of the limiting plate 51. The space between the two limiting guide blocks 54 is formed for the width-fixing mechanism 1 to pass through after the sheet bamboo material is width-fixed.

[0054] It is understood that in this embodiment, the front end of the limiting plate 51 is located between the two limiting members 52 and the rear end is located between the two limiting guide blocks 54 according to the conveying direction. The sheet bamboo material passes through the two limiting members 52 and the two limiting guide blocks 54 in sequence. At the same time, the sheet bamboo material is pressed by the limiting plate 51 and the pressing arm 42 in the thickness direction.

[0055] It is understood that in this embodiment, the limiting width adjustment member 6255 between the two limiting members 52 is preferably a wedge-shaped structure. Since the elastic pressure member 57 makes the two limiting members 52 tend to move towards each other, the relative distance between the two limiting members 52 can be controlled by inserting the limiting width adjustment member 6255 between at least a portion of the two limiting members 52, thereby achieving the function of limiting and adjusting the width of the sheet bamboo material.

[0056] Specifically, in this embodiment, the fine-tuning structure 53 is preferably a right-angle bracket, one side of which is slidably mounted on the frame, and the two limiting guide blocks 54 are slidably mounted on the remaining side of the right-angle bracket.

[0057] It is understood that in this embodiment, the position adjustment of the fine-tuning structure 53 and the two limiting guide blocks 54 can be achieved by adjusting the relative position of the right-angle bracket and the frame, and the relative distance between the two limiting guide blocks 54 can be adjusted by sliding.

[0058] Specifically, each limiting member 52 is rotatably sleeved on the vertical shaft 56, and the two vertical shafts 56 are connected to the frame via the elastic pressure member 57 so that the two limiting members 52 tend to move in opposite directions. Each vertical shaft 56 is rotatably connected to the frame via the connecting arm 58.

[0059] Understandably, in this embodiment, the vertical shaft 56 is used to support and guide the opposing movement between the two limiting members 52. The vertical shaft 56 is rotatably connected to the frame via the connecting arm 58, allowing the vertical shaft 56 to rotate within a certain angle, thereby driving the limiting members 52 to move. The elastic pressure member 57 can provide automatic compensation and fine-tuning capabilities, so that the two limiting members 52 maintain balance and coordination.

[0060] Specifically, the limiting member 52 has a conical sleeve structure, and the outer diameter of the limiting member 52 gradually decreases from bottom to top.

[0061] It is understood that in this embodiment, the limiting member 52 has a conical sleeve structure and the outer diameter gradually decreases from bottom to top. Therefore, the material between the two limiting members 52 gradually increases from bottom to top in the vertical direction through the space, and the sheet bamboo material is forced to fit more tightly against the limiting plate 51, thereby improving the pressing effect.

[0062] Referring to Figures 1, 2, and 3, in one specific embodiment of this application, the power assembly includes a plurality of motors 71, and the first part, the second part, and the third part each include at least one motor 71, and the lifting adjustment assembly 7 is a motor 71 lifting adjustment assembly 7 for wire drawing. A motor 71 is installed on each motor 71 lifting adjustment assembly 7, and each motor 71 is connected to at least one power shaft that is rotatably connected to the frame through a belt drive structure. The power shaft includes a first power shaft 8 and a second power shaft 9, and the power shaft is one of a transmission shaft and a cutter shaft.

[0063] Specifically, in this embodiment, there are several sets of conveying components 11, and each conveying component 11 or two adjacent sets of conveying components 11 are connected to the corresponding motor 71 of the first part through a belt / chain drive structure; the first power shafts 8 included in the width fixing mechanism 1, the thickness fixing mechanism 2, and the wire drawing forming mechanism 3 are distributed adjacently, and each first power shaft 8 or two adjacent first power shafts 8 are connected to the corresponding motor 71 of the second part through a belt / chain drive structure; the second power shafts 9 included in the thickness fixing mechanism 2 and the wire drawing forming mechanism 3 are distributed adjacently, and each second power shaft 9 or two adjacent second power shafts 9 are connected to the corresponding motor 71 of the third part through a belt / chain drive structure.

[0064] It is understood that in this embodiment, at least one motor 71 is connected to two transmission components 11 or two power shafts with the same direction of rotation through a belt / chain drive structure, which reduces production costs and avoids the phenomenon of the power shaft spinning idly.

[0065] Specifically, there are five sets of conveying components 11 distributed in the conveying direction, and each conveying component 11 is a transmission gear assembly. At least some of the gears of the two sets of conveying components 11 closest to the discharge side of the conveying mechanism are respectively immersed in the lubricating oil in the corresponding lubricating oil tank 111.

[0066] Specifically, when there are three sets of conveying components 11 on the feeding side of the slitting and drawing equipment, two sets of conveying components 11 are connected to a corresponding motor 71 of a first part through a belt / chain drive structure, while the remaining set of conveying components 11 is connected to one of the two adjacent sets of conveying components 11 through a synchronous drive structure 12.

[0067] It is understood that in this embodiment, the motors 71 of the first, second, and third parts of the powertrain drive the power shafts included in the transmission assembly 11, the width-fixing mechanism 1, the thickness-fixing mechanism 2, and the wire drawing and forming mechanism 3 respectively through belt / chain drive structures. The power shaft included in the transmission assembly 11 is a transmission shaft, and the several first power shafts 8 and second power shafts 9 included in the width-fixing mechanism 1, the thickness-fixing mechanism 2, and the wire drawing and forming mechanism 3 achieve width-fixing processing, thickness-fixing processing, and wire drawing and forming processing by connecting to processing tools.

[0068] It is understood that in this embodiment, each motor 71 lifting adjustment assembly 7 is equipped with a motor 71, and each motor 71 is connected to the power shaft of the transmission assembly 11 or the power shaft of the width-fixing mechanism 1, the thickness-fixing mechanism 2, and the wire drawing and forming mechanism 3 through a belt / chain drive structure. The motor 71 lifting adjustment assembly 7 is used to adjust the height of the motor 71 to adapt to different working requirements. The motor 71 lifting adjustment assembly 7 ensures the smoothness of the lifting adjustment and further ensures the balance of the belt / chain drive structure during the lifting adjustment process.

[0069] Referring to Figure 6, in one specific embodiment of this application, the transmission gear assembly includes a plurality of meshing transmission gear sets disposed on a frame. At least a portion of the transmission gear sets is immersed in a lubricating oil tank 111. The lubricating oil tank 111 is provided with two oil-blocking connecting portions 112 fixed on the frame and located on the outer side of the rotation direction of the transmission gear sets.

[0070] It is understood that in this embodiment, the transmission gear set consists of multiple meshing gears used to transmit power. The lubricating oil in the lubricating oil groove 111 is evenly distributed onto the transmission gear assembly through the meshing of the gears, reducing friction between gears, minimizing wear, and extending equipment life. The oil-blocking connection 112 is located on the outer side of the transmission gear set in the direction of rotation, preventing lubricating oil from overflowing, maintaining the circulation of lubricating oil within the lubricating oil groove 111, and protecting the external environment from pollution.

[0071] Specifically, each oil-blocking connection 112 is provided with an oil return groove 113, and the oil return groove 113 is located on the inner side of the two oil-blocking connections 112 respectively. At least part of the transmission gear set is located in the oil return groove 113. The oil return groove 113 is interconnected with the lubricating oil groove 111, and the connection between the oil return groove 113 and the lubricating oil groove 111 is an arc-shaped connection structure.

[0072] It is understood that in this embodiment, an oil return groove 113 communicating with the lubricating oil groove 111 is provided on the oil-blocking connection 112. During the operation of the gear, the oil-blocking connection 112 can collect the lubricating oil splashed out by the gear rotation and reintroduce it into the lubricating oil groove 111, thereby optimizing the circulation path of the lubricating oil, improving the utilization rate of the lubricating oil, and reducing the risk of lubricating oil contamination.

[0073] Specifically, the depth of the lubricating oil groove 111 gradually increases from the connection point with the two return oil grooves 113 toward the middle to form an inverted trapezoidal groove structure.

[0074] It is understood that the inverted trapezoidal groove structure of the lubricating oil groove 111 in this embodiment, through the gradually increasing groove depth, enables the lubricating oil to maintain a stable flow state during the flow process and can effectively guide the lubricating oil to the key parts that need lubrication.

[0075] Specifically, the top of each oil baffle connection 112 is fixed to the frame by a connecting structure.

[0076] Specifically, the connection structure includes a connecting part and a plurality of fasteners 10, the connecting part being fixed to the frame by the plurality of fasteners 10. The fasteners 10 are preferably bolts.

[0077] It is understood that in this embodiment, the oil-blocking connecting part 112 is fixed to the frame by a connecting structure to ensure that it will not shift or loosen during operation. The connecting structure consists of a connecting part and a fastener 10, wherein the fastener 10 is preferably a bolt, which not only ensures the stability of the oil-blocking connecting part 112, but also facilitates maintenance and replacement.

[0078] Specifically, the oil-blocking connection 112 is positioned perpendicular to the lubricating oil groove 111. It is understood that in this embodiment, the oil-blocking connection 112 and the lubricating oil groove 111 are positioned perpendicular to each other, allowing splashed lubricating oil to quickly flow into the lubricating oil groove 111 via the return oil groove 113 under gravity, preventing lubricating oil loss.

[0079] Specifically, an oil drain hole 114 is provided on one side wall of the lubricating oil tank 111 to facilitate the replacement of lubricating oil.

[0080] Specifically, at least part of the lubricating oil tank 111 is made of transparent material, and an oil level indicator is provided on the lubricating oil tank 111 to facilitate observation of the lubricating oil level and condition, and to promptly detect problems such as insufficient lubricating oil or contamination.

[0081] Referring to Figures 4 and 5, in one specific embodiment of this application, the lifting adjustment component 7 includes a base 72 and a support platform 73. The support platform 73 is connected to the base 72 through a lifting drive component, and a limiting guide component is provided between the support platform 73 and the base 72. At least a portion of the limiting guide component is fixed to the base 72, and the remaining portion is fixed to the support platform 73. The at least portion and the remaining portion are slidably connected in the lifting direction.

[0082] Specifically, in this embodiment, the top surface of the support platform 73 is provided with a downwardly recessed upper recess 731, and the base 72 is provided with an upwardly protruding limiting protrusion 721. A limiting space 74 is formed between the limiting protrusion 721 and the upper recess 731, and a clearance space 75 is formed between the limiting protrusion 721 and the frame to accommodate at least a portion of the limiting guide component, wherein at least a portion of the limiting guide component is located within the limiting space 74, and the remaining portion is located within the clearance space 75.

[0113] Specifically, the working principle of a slitting and wire drawing device in this embodiment is as follows:

[0114] The bamboo sheet is fed into the feeding side of the splitting and drawing equipment with the green side facing up. The conveying mechanism first conveys the bamboo sheet to the width fixing mechanism 1 for width fixing.

In the thickness fixing mechanism 2, the green side and yellow side are successively cut and thickened by the green side jointing knife, the yellow side jointing knife, the green side thickness fixing knife, and the yellow side thickness fixing knife. After the jointing and thickness fixing is completed, the conveying mechanism sends the bamboo sheet to the drawing and shaping mechanism. In the drawing and shaping mechanism, the bamboo sheet is drawn and shaped by two staggered drawing and shaping knives. The bamboo sheet after the drawing and shaping is then conveyed to the discharge side.
