Detailed Description

In order that the objects and advantages of the invention will be more clearly understood, the following description is given in conjunction with the accompanying examples. It is to be understood that the following text is merely illustrative of one or more specific embodiments of the invention and does not strictly limit the scope of the invention as specifically claimed.

The embodiment of the application provides an equipment for flattening wide bamboo board of production, has solved the bamboo section that appears among the prior art and has cracked easily and can not adapt to the not problem of unidimensional bamboo section exhibition demand at the exhibition in-process.

In order to solve the problem of the above troubles, the technical scheme in the embodiment of the application has the following general idea:

as shown in fig. 1 to 7, the apparatus includes a housing 700, and the housing 700 is provided with: the material guide mechanism 100 is used for guiding and conveying the bamboo sections with the cutting seams along the length direction of the bamboo sections, and in the guiding and conveying process of the bamboo sections, the seams on the bamboo sections are arranged upwards; the spreading mechanism 200 is arranged behind the material guiding mechanism 100 along the length direction of the bamboo segments, and comprises two spreading parts which are arranged oppositely and a supporting part 210 for supporting the bamboo segments, wherein the two spreading parts press the inner walls of the bamboo segments by extending downwards and spread the bamboo segments on the supporting part 210 into bamboo boards by separating from each other; and a shaping and conveying mechanism 300, one end of which is intersected with the spreading mechanism 200, for receiving and conveying the bamboo boards moved out of the supporting part 210 and cooling and shaping the bamboo boards in the conveying process.

According to the device for flattening and producing the wide bamboo boards, the material guide mechanism 100 is arranged, and bamboo sections with cutting seams are guided and sent along the length direction of the bamboo sections; the bamboo section is flattened into the bamboo board by the two spreading parts in a way of being far away from each other through the spreading mechanism 200 comprising the supporting part 210 and the two spreading parts which are oppositely arranged, the supporting part 210 provides a supporting function for the bamboo section with the upward cutting seam, and the two spreading parts extend downwards to press the inner wall of the bamboo section; the shaping conveying mechanism 300 is used for achieving the purposes of conveying bamboo boards and cooling and shaping the bamboo boards in the conveying process; through the arrangement, the bamboo section flattening device not only can adapt to flattening requirements of bamboo sections with various sizes, but also is favorable for reducing the cracking rate of the bamboo sections in the flattening process.

As shown in fig. 2 to 4, in order to make the posture of the bamboo section when feeding the bamboo section consistent with the posture of the bamboo section to be spread on the spreading mechanism 200, the feeding posture of the bamboo section needs to be adjusted and positioned, and the preferred solution of the embodiment of the present application is: the material guiding mechanism 100 comprises a material guiding shaft 110 inserted into the bamboo section and a shell 120 fixedly arranged on the periphery of the material guiding shaft 110, wherein the material guiding shaft 110 is horizontally arranged and fixedly arranged on the rack 700 through a hanging rod; the inner diameter of the shell 120 is matched with the maximum outer diameter of the bamboo section to be flared, and the material guide shaft 110 and the spreading part are arranged along the same direction. A guiding cavity for the bamboo sections to pass through is formed between the shell 120 and the guiding shaft 110, the cross section of the guiding cavity is matched with the radial size range and the thickness range of the bamboo sections to be spread, and the requirement that the bamboo sections cannot be shifted too far along the radial direction in the guiding and conveying process is met, so that the problem that the guiding and conveying path of the bamboo sections cannot correspond to the spreading part due to large positioning deviation is avoided.

As shown in fig. 1 to 4, although the bamboo segments are cut in advance along the length direction before being spread, some bamboo segments may not be smoothly moved into the bamboo segments due to relatively small cross-sectional size, and if the cutting seams are small, the time required for spreading the bamboo segments is increased, which also affects the production efficiency of the bamboo panel. Therefore, in order to improve the spreading efficiency of the bamboo segments, the embodiment of the present application further provides the following solutions: the device further comprises a flaring mechanism 400 which is fixedly arranged on the path of the guiding mechanism 100 for guiding the bamboo sections and is used for performing the flaring treatment on the cutting seams on the passing bamboo sections. The principle is as follows: in the process of guiding and conveying the bamboo sections by the material guide mechanism 100, the cutting seams on the bamboo sections are expanded by the flaring mechanism 400, so that the cutting seams are increased, and the unfolding part is favorably placed in the bamboo sections and the unfolding efficiency of the bamboo sections is improved.

Specifically, as shown in fig. 2 to 4, the flaring mechanism 400 may be a wedge block 410, the wedge block 410 is arranged corresponding to the cutting seam of the bamboo segment on the guiding mechanism 100, the section width of the wedge block 410 is increased along the guiding direction of the bamboo segment, and the wedge block 410 is installed on the top of the guiding shaft 110.

As shown in fig. 3 and 4, for the expanding manner of the cutting seam, an optional embodiment may be adopted in which the cross section of the material guiding shaft 110 gradually increases along the guiding direction of the bamboo segments, and the minimum outer diameter of the material guiding shaft 110 is adapted to the maximum inner diameter of the bamboo segments to be flared. Through passing through the bamboo section guide shaft 110, can be with the inner chamber increase of bamboo section, can also play the purpose with the cutting seam enlarges simultaneously. Of course, this embodiment can also be used in combination with the wedge block 410, which not only can achieve the purpose of expanding the cutting seams, but also can expand the inner cavity of the bamboo section, thereby being more convenient for the subsequent spreading part to spread the bamboo section.

As shown in fig. 1 to 4, when the guide shaft 110 is provided with the enlarged cross section, the rear end of the casing 120 is not easily arranged flush with the rear end of the guide shaft 110, because the bamboo section is gradually enlarged by the guide shaft 110, the bamboo section at the rear end of the guide shaft 110 is likely to be caught by the inner wall of the casing 120, which makes it difficult to further guide the bamboo section forward, and thus the normal operation of the production process is affected. Therefore, the further preferable scheme of the embodiment is as follows: the tail end of the guide shaft 110 extends to the outside of the housing 120. More specifically, if the guide shaft 110 and the head end of the housing 120 are flush, the axial length of the guide shaft 110 is greater than the length of the housing 120 in the axial direction of the guide shaft 110. The specific length of the guide shaft 110 extending from the tail end to the outside of the shell 120 may be set according to the size range of the bamboo segments to be spread and the size of the cavity between the shell 120 and the guide shaft 110.

Since the guiding shaft 110 is mounted on the frame 700 through the suspension rod, if the guiding shaft 110 is axially displaced during the guiding process of the bamboo segments, the corresponding relationship between the bamboo segments and the spreading portion will be affected, and therefore, in this case, the axial degree of freedom of the guiding shaft 110 is further restricted. The embodiment of the application further preferably adopts the following scheme: the end part of the guide shaft 110 close to the spreading mechanism 200 is connected with the frame 700 through a limiting suspension rod, one end of the limiting suspension rod is connected with the guide shaft 110, the other end of the limiting suspension rod is fixed on the frame 700, and the limiting suspension rod is used for limiting the guide shaft 110 to axially shift in the process of pushing the bamboo section along the guide shaft 110. The principle is as follows: one end of the limiting suspension rod is fixedly connected/abutted with the end part of the guide shaft 110, and the other end of the limiting suspension rod is fixed on the rack 700, so that the purpose of further restricting the axial degree of freedom of the guide shaft 110 is achieved, and the guide shaft 110 is effectively prevented from axially shifting in the guide and conveying process of the bamboo section.

Of course, if the connection structure between the wedge block 410 and the guide shaft 110 is stable enough, the wedge block 410 can be fixed on the frame to fix the guide shaft 110, as long as the guide shaft 110 can be stable in structure in the using process.

When adorning the bamboo section on guide axle 110, in order to carry out quick location to the cutting seam of bamboo section, can extend to set up the location arch at guide axle 110 head end surface upside, perhaps, set up the location arch at casing 120 head end internal surface upside to carry out quick location to the bamboo section, be favorable to the quick material loading of bamboo section.

In order to enable the spread bamboo boards to keep the shape in the conveying process and to be naturally cooled and shaped, the preferable scheme of the embodiment of the application is as follows: as shown in fig. 1 to 4, the shaping conveying mechanism 300 includes a plurality of sets of conveying rollers arranged on the rack 700 in an arrangement shape along the moving direction of the bamboo boards, each conveying roller 310 is composed of conveying rollers 310 arranged up and down correspondingly, the upper and lower conveying rollers 310 are rotatably mounted on the rack 700, the axial direction of each conveying roller 310 is consistent with the length direction of the bamboo section on the material guiding mechanism 100, the upper and/or lower conveying rollers 310 are rotated to drive the bamboo boards to move, and the roller surfaces of the upper and lower conveying rollers 310 are in contact with the board surfaces of the bamboo boards. The principle is as follows: through carrying the bamboo clapper from between the conveying roller 310 that two rows of upper and lower correspondences were arranged, be favorable to the bamboo clapper to keep the form in transportation process, moreover in transportation process, because there is the space between the conveying roller 310, be favorable to the heat dissipation and the cooling of bamboo clapper, and then make the bamboo clapper can fix a shape.

Referring to fig. 2, in order to make the conveying roller pair capable of adapting to the conveying of bamboo boards with different thicknesses, the preferred embodiment of the present embodiment is that the conveying roller 310 positioned on the upper side is installed on the frame 700 in a floating manner along the vertical direction; the lower conveying roller 310 is vertically mounted to the frame 700 in a limited manner. The principle is as follows: through with the spacing installation of downside conveying roller 310 along the vertical direction on frame 700, with the unsteady installation of upside conveying roller 310 along the vertical direction to the interval between the roll surface of upside conveying roller 310 can be adjusted according to the thickness adaptability of bamboo clapper, in order to reach the purpose that adapts to different thickness bamboo clappers and carry.

Specifically, the upper conveying roller 310 may be mounted on one a frame 320, the a frame 320 may be vertically slidably mounted on the frame 700, the lower conveying roller 310 may be mounted on the frame 700 via the B frame 330, a compression spring that extends and contracts in the vertical direction may be mounted between the upper side of the a frame 320 and the frame 700, or a tension spring that extends and contracts in the vertical direction may be mounted between the lower side of the a frame 320 and the B frame 330.

Further, the sliding guide assembly of the a frame 320 and the rack 700 may be configured such that a guide post is fixedly disposed on the B frame 330, a guide hole is formed on the a frame 320 to be engaged with the guide post, and the guide post may be disposed concentrically with the compression spring/extension spring.

In order to drive the bamboo boards to move between the conveying rollers 310 on the upper side and the lower side, the device further comprises a C adjusting mechanism which is used for adjusting the conveying rollers 310 on the lower side to synchronously rotate in the same direction. The C adjusting mechanism may drive all the lower conveying rollers 310 to rotate, or drive the spaced conveying rollers 310 to rotate, as long as the stable conveyance of the bamboo boards can be achieved.

In a specific implementation, the C adjusting mechanism is composed of a chain transmission assembly connected between two adjacent conveying rollers 310 on the lower side. Of course, the shaft ends of two adjacent conveying rollers 310 may be connected in a transmission manner by means of a synchronous belt transmission.

As shown in fig. 5 to 7, an embodiment of the present application further provides a spreading mechanism for spreading bamboo segments, which includes a rack 700, where the rack 700 is provided with: a support portion 210 for placing the bamboo section to be spread and arranging the cutting seam on the bamboo section upward; and the spreading part and the rack 700 form sliding assembly along the vertical direction, the spreading part is provided with two parts and is arranged oppositely, and the two parts gradually spread the bamboo sections into the bamboo boards by pressing the inner walls of the bamboo sections downwards and keeping away from each other.

In the spreading mechanism for spreading bamboo sections provided by this embodiment, the supporting portion 210 is provided to support the bamboo sections to be spread, and then two opposite spreading portions are provided, and the two spreading portions are assembled on the rack 700 in a sliding manner along the vertical direction, so that the two spreading portions can gradually spread the bamboo sections into bamboo boards by pressing the inner walls of the bamboo sections downwards and keeping away from each other; the bamboo section flattening device can meet the flattening requirements of bamboo sections with various sizes, and can effectively prevent the bamboo sections from cracking in the flattening process.

In specific implementation, as shown in fig. 5 and 7, the rack 700 is further provided with a movable frame 230 and two connecting arms 240 arranged oppositely, the movable frame 230 is slidably assembled on the rack 700 along the vertical direction, first ends of the two connecting arms 240 are movably installed on the movable frame 230, second ends of the two connecting arms 240 are respectively assembled and connected with one spreading portion, the movable frame 230 enables the spreading portion to press the inner wall of the bamboo segment through downward movement, and the two connecting arms 240 enable the two spreading portions to be away from each other through posture change.

The two connecting arms 240 may be horizontally slidably mounted on the movable frame 230, or rotatably mounted on the movable frame 230. In order to adjust the postures of the two connecting arms 240, in the preferred embodiment, as shown in fig. 5 and 7, the first end of the connecting arm 240 is rotatably mounted on the movable frame 230, the two connecting arms 240 make the two spreading parts move away from each other by rotating in opposite directions relative to the movable frame 230, and the two connecting arms 240 are in two states, one of which is: the two connecting arms 240 are vertically arranged, and the two spreading parts can be accommodated in the bamboo sections to be spread; the second is as follows: the two connecting arms 240 are gradually turned to be arranged in a horizontal state, the two spreading parts gradually spread the bamboo sections into a bamboo board shape, and the two spreading parts are pressed against the bamboo board in a pressure-sharing manner. The first end of the connecting arm 240 refers to the upper end of the connecting arm 240 when the connecting arm 240 is vertically disposed, and the second end of the connecting arm 240 refers to the lower end of the connecting arm 240 when the connecting arm 240 is vertically disposed. The principle of the scheme is that when the two connecting arms 240 are arranged in the vertical posture, the distance between the two spreading parts is the closest, and at the moment, the bamboo sections with the cutting seams can be sleeved on the peripheries of the two spreading parts, or the spreading parts can be moved downwards to extend into the bamboo sections under the condition that the cutting seams are large enough; after the two spreading parts press the inner walls of the bamboo sections, the two connecting arms 240 are rotated reversely relative to the movable frame 230, so that the two spreading parts move in directions away from each other along the inner walls of the bamboo sections, and the bamboo sections are gradually flattened.

In order to realize that the two connecting arms 240 can make the lower ends of the two connecting arms 240 move away from each other in the process of moving down along with the movable frame 230, in the preferred embodiment, the frame 700 is further provided with an a adjusting mechanism, and the a adjusting mechanism is used for adjusting the second ends of the two connecting arms 240 to move away from each other in the process of moving down the movable frame 230.

As shown in fig. 5 to 7, the preferred scheme of the a adjustment mechanism provided in this embodiment is: the adjusting mechanism a is composed of two triggering guide parts 500 fixedly arranged on the frame 700, and the two triggering guide parts 500 are respectively used for forming guiding cooperation with the two spreading parts, so that the two spreading parts are far away from each other in the process of moving downwards.

Specifically, the triggering guide part 500 may be formed by two guide surfaces, the two guide surfaces are symmetrically arranged about a plane a, and the height of the guide surfaces gradually decreases from one end close to the plane a to one end far away from the plane a, which is a symmetrical surface of the two connecting arms 240.

Further, the triggering guide part 500 and the end of the spreading part far from the feeding of the bamboo sections along the length direction of the bamboo sections form a guiding fit to prevent the feeding operation of the bamboo sections on the spreading part from being affected.

As shown in fig. 5 to 7, in order to reduce the resistance applied to the spreading portion during the process of flattening the bamboo segments, the preferred scheme of the present embodiment is that the spreading portion has a spreading roller 220, the spreading roller 220 is rotatably mounted at the second end of the connecting arm 240, the axial direction of the spreading roller 220 is consistent with the length direction of the bamboo segments to be spread on the supporting portion 210, and the two spreading rollers 220 press the inner walls of the bamboo segments and roll in the direction away from each other to spread the bamboo segments; the two triggering guides 500 are respectively in guiding engagement with one end of the two spreader rolls 220 along the axial direction thereof. The principle of the scheme is that the spreading roller 220 rotatably mounted at the lower end part of the connecting arm 240 is used as a spreading part, so that the spreading roller 220 moves along the inner wall of the bamboo section in a rolling manner in the spreading process of the bamboo section, the resistance borne by the spreading part in the spreading process is effectively reduced, and the spreading efficiency is improved; in addition, because the spreading rollers 220 spread the bamboo sections in a rolling manner, the friction between the spreading parts and the inner walls of the bamboo sections is reduced, so that the damage to the inner walls of the bamboo sections in the spreading process can be reduced, and the bamboo boards with better quality can be obtained.

Referring to fig. 5 to 7, since the sectional sizes of the bamboo segments at different positions on the same bamboo are different and the thicknesses of the different bamboos are different, the widths of the bamboo segments are necessarily different after the bamboo segments are spread, and the size range of the bamboo segments is smaller if only one spreading roller 220 is provided at each position. Therefore, in order to be able to meet the flattening requirement of bamboo segments with a wide size range, the preferred solution of the embodiment is as follows: the two ends of the spreading roller 220 are rotatably provided with roller seats 250, the spreading rollers 220 are arranged on the roller seats 250 in an arrangement manner, and the roller seats 250 are rotatably arranged on the connecting arm 240; when the connecting arm 240 is vertically arranged, the spreading rollers 220 located at the same position are arranged along the arm length direction of the connecting arm 240, when the connecting arm 240 is gradually turned over to be arranged in a horizontal state, the spreading rollers 220 located at two positions are gradually turned over to be arranged along the horizontal direction, and at least one of the spreading rollers 220 located at the same position keeps contact with the edge of the bamboo board.

Further, as shown in fig. 5 to 7, two spreading rollers 220 are mounted on each roller base 250, and the two spreading rollers 220 are respectively located at two sides of the connection position of the roller base 250 and the connecting arm 240.

When the bamboo segments are flattened into bamboo boards by the spreader roll 220, if the bamboo boards are manually removed from between the spreader roll 220 and the supporting portion 210, the efficiency is low, and the bamboo boards are not easy to maintain the board-shaped form during the removal process. Therefore, in order to improve the efficiency of removing the bamboo boards and maintain the shape of the bamboo boards, the preferred scheme of the embodiment is as follows: the apparatus further comprises a B adjusting mechanism for adjusting the two spreading rollers 220 to rotate synchronously and in the same direction when the bamboo segments are completely spread into a bamboo board shape, so that the bamboo board is moved out to the side of the supporting portion 210. Wherein, the moving direction of the bamboo board is consistent with the moving direction of one of the spreading rollers 220 in the process of spreading the bamboo sections.

As shown in fig. 1 to 7, the embodiment of the B adjustment mechanism specifically provided in this example is: the B adjusting mechanism comprises a driving unit 610, a B1 transmission unit is arranged between the driving unit 610 and one of the spreading rollers 220 and/or a B2 transmission unit is arranged between the driving unit 610 and the other spreading roller 220, the B1 transmission unit is the same as the B2 transmission unit, the B1 transmission unit comprises a clutch component 621, the clutch component 621 is in a transmission disconnection state before the bamboo section is completely spread into a bamboo board, a trigger 640 is arranged on the rack 700, the trigger 640 is positioned on the moving path of the clutch component 621 and is used for triggering the clutch component 621 to be in a transmission connection state when the bamboo section is completely spread into the bamboo board shape, so that the driving unit 610 and the spreading rollers 220 form transmission connection; when the clutch 621 is in transmission connection, the driving unit 610 adjusts the two spreader rolls 220 to rotate synchronously in the same direction. The principle is as follows: before the bamboo segments are completely spread into the bamboo boards, the clutch component 621 is in a transmission disconnection state, the rolling directions of the two spreading rollers 220 along the inner walls of the bamboo segments are opposite, until the bamboo segments are completely spread, the clutch component 621 is in a transmission connection state, and the two spreading rollers 220 synchronously rotate in the same direction under the driving of the driving unit 610 to move out the bamboo boards.

It should be noted that there are two ways of synchronously rotating the two spreading rollers 220 in the same direction, one of them is: when the driving unit 610 adjusts one of the spreading rollers 220 to rotate, the spreading roller 220 at the position plays a role of pulling the bamboo board to move out, while the other spreading roller 220 rotates along with the movement of the bamboo board in the process of moving out the bamboo board, and the rotating directions of the two spreading rollers 220 are consistent and synchronous; the other is as follows: when the driving unit 610 adjusts the two spreading rollers 220 to rotate synchronously in the same direction, the two spreading rollers 220 both play a role in pulling the bamboo boards, so that the bamboo boards are more smoothly moved out, and the mode is the preferred mode in the practical application environment, and the condition that the bamboo boards cannot be smoothly moved out due to insufficient pulling force of one spreading roller 220 can be effectively avoided.

As shown in fig. 2 to 7, in order to realize that the two spreading rollers 220 are driven by the driving unit 610 to synchronously rotate in the same direction, the embodiment preferably has a B1 transmission unit and a B2 transmission unit respectively disposed between the driving unit 610 and the two spreading rollers 220.

The scheme specifically provided by the embodiment is as follows: the upper end of the connecting arm 240 is rotatably connected with the movable frame 230 through the rotating shaft A260, and the spreading roller 220 is rotatably installed at the lower end of the connecting arm 240; the driving unit 610 includes a driving shaft 611, and the axial direction of the driving shaft 611 is parallel to the axial direction of the a rotating shaft 260 and the axial direction of the spreading roller 220, respectively; the B1 driving unit comprises a B11 driving assembly 622 arranged between the a rotating shaft 260 and the driving shaft 611 and a B12 driving assembly 623 arranged between the a rotating shaft 260 and the spreading roller 220; the B12 transmission component 623 is provided with a clutch component 621, and the clutch component 621 is used for adjusting the transmission connection state of the B12 transmission component 623; when the clutch component 621 is in a transmission connection state, the rotating shaft a 260 and the spreading rollers 220 form a transmission connection, and the rotating driving shaft 611 adjusts the two spreading rollers 220 to synchronously rotate in the same direction.

The B11 transmission assembly 622 can be composed of a driving gear 622a mounted on the driving shaft 611 and a transmission gear 622B mounted on the a rotation shaft 260, wherein the driving gear 622a is engaged with the transmission gear 622B, and the rotation shaft 611 is rotated to drive the a rotation shaft 260 to rotate.

Regarding the implementation of the B12 transmission assembly 623, there are two types:

referring to fig. 1 to 7, one is: when the spreading rollers 220 are arranged on the roller base 250, the roller base 250 is rotatably mounted at the lower end of the connecting arm 240 through the B rotating shaft 280, and the axial direction of the B rotating shaft 280 is parallel to the axial direction of the driving shaft 611; the B12 transmission component 623 comprises a B121 sub transmission component arranged between the A rotating shaft 260 and the B rotating shaft 280 and a B122 sub transmission component arranged between the B rotating shaft 280 and each spreading roller 220, and the clutch component 621 adjusts the transmission connection state of the B12 transmission component 623 by adjusting the transmission connection state of the B121 sub transmission component and the B122 sub transmission component.

Specifically, an A chain wheel 623a1 arranged on the A rotating shaft 260 and a B chain wheel 623a2 arranged on the B rotating shaft 280 form the B121 sub-transmission assembly, and the A chain wheel 623a1 is in chain transmission connection with the B chain wheel 623a 2; the A belt wheel 623B1 which is rotatably arranged on the B rotating shaft 280 and the B belt wheel 623B2 which is concentrically arranged at the shaft end part of the spreading roller 220 form the B122 sub transmission assembly, and the A belt wheel 623B1 is respectively connected with the B belt wheels 623B2 on the same roller seat 250 in a synchronous and same-direction transmission manner through a transmission belt; the clutch pack 621 is used to adjust the transmission connection state between the B sprocket 623a2 and the a pulley 623B 1.

Secondly, when only one of the spreader rolls 220 is directly and rotatably mounted at the lower end of the connecting arm 240, the a sprocket 623a1 mounted on the a rotating shaft 260 and the B sprocket 623a2 coaxially mounted with the spreader roll 220 constitute a B12 transmission assembly 623.

The clutch component 621 provided by this embodiment is implemented in such a way that the clutch component 621 is formed by a sliding sleeve slidably guided and assembled along the axial line of the B sprocket 623a2, the B sprocket 623a2 is synchronously and unidirectionally connected with the sliding sleeve, and the sliding sleeve is in two states, one of which is: the sliding sleeve is in contact with the A belt wheel 623B1 in a transmission connection position, so that the B chain wheel 623a2 and the A belt wheel 623B1 can synchronously rotate in the same direction; the second is as follows: the transmission disconnection position that the sliding sleeve is separated from the A belt wheel 623B1 disconnects the transmission connection of the B chain wheel 623a2 and the A belt wheel 623B 1; the sliding sleeve is connected with an A reset piece, and the A reset piece is used for driving the sliding sleeve to move to a transmission disconnection position separated from the A belt wheel 623b 1.

During specific implementation, the A reset piece can be a tension spring or a compression spring.

As shown in fig. 5, the trigger 640 of the above embodiment may be formed by a trigger ramp that drives the sliding sleeve to move into a driving connection with the a pulley 623b1 by forming a ramp with the sliding sleeve.

As shown in fig. 3, the driving shaft 611 is connected to a motor, and the driving shaft 611 can be driven to rotate by starting the motor.

If the spreading roller 220 is assembled on the connecting arm 240 through the roller seat 250, after the bamboo sections are spread, the connecting arm 240 moves upward along with the movable frame 230 and gradually returns to the standing posture under the action of gravity, and the roller seat 250 may not be automatically reset when the connecting arm 240 returns to the standing posture due to the inertia effect, in this case, the posture of the roller seat 250 needs to be manually adjusted, so that the next bamboo section is spread again, and then the manual reset not only affects the production efficiency, but also increases the workload. In order to solve this problem, the preferred solution of this embodiment is: a B reset member is connected between the roller base 250 and the connecting arm 240, and the B reset member is used for driving the roller base 250 to turn over to a state that the arrangement direction of each spreading roller 220 is consistent with the arm length direction of the connecting arm 240.

During specific implementation, the B reset piece can adopt a clamp spring or a torsion spring.

As shown in fig. 4 to 6, in order to reduce the resistance force applied when the bamboo board is removed from the supporting portion 210, the bamboo board is removed more smoothly. In specific implementation of the supporting portion 210 provided in this embodiment, the supporting portion 210 has a plurality of a-axis rollers 211 arranged in an array, each of the a-axis rollers 211 is rotatably mounted on the frame 700, an axial direction of the a-axis roller 211 is identical to an axial direction of the spreading roller 220, and the a-axis roller 211 is used for supporting the bamboo segments on the supporting portion 210 and rolling along with movement of the bamboo segments after the bamboo segments are completely spread into the bamboo boards.

Referring to fig. 6, if the spreader roller 220 is mounted on the connecting arm 240 through the roller base 250, the roller base 250 and the trigger guide 500 form a guiding fit, and the trigger guide 500 functions as a guide rail in actual use.

As shown in fig. 1 to 5 and 7, the movable frame 230 is connected to an expansion rod of an air cylinder, the air cylinder is disposed above the movable frame 230, and the air cylinder is fixedly mounted on the frame 700.
