The bamboo chip node removing and sorting device comprises an inner node removing device and a sorting device which are arranged in tandem along an axis, wherein a clamping and conveying device is arranged between the inner node removing device and the sorting device or in front of the sorting device,
the inner section removing device comprises a conical cylinder with a small back and a large front, at least two compression half rings are arranged in the circumferential direction of the conical cylinder, the compression half rings are connected with a compression power device which drives the compression half rings to move along the radial direction of the conical cylinder, and scraping rings are arranged on the periphery of the large end of the conical cylinder;
the pressing semi-ring is driven by a pressing power device to tightly press the bamboo chips passing through the space between the conical cylinder and the pressing semi-ring on the scraping ring;
the sequencing device comprises a sleeve and two shifting forks positioned at two ends of the sleeve; the sleeve becomes e shape, has inner tube, urceolus, forms bilayer structure, and clearance t between inner tube and the urceolus satisfies: h is less than t and less than 2h, the thickness of the bamboo chips is h, the shifting forks comprise a plurality of shifting forks extending along the radial direction of the sleeve, and the two shifting forks are connected with a shifting fork driving device which drives the shifting forks to rotate around the axis and is positioned in the sleeve; a transverse outlet is arranged between the side edge of the inner cylinder far away from the axis and the side edge of the outer cylinder;
when the bamboo chips axially penetrate through a gap between the inner cylinder and the outer cylinder, two ends of each bamboo chip are positioned between two adjacent shift levers of the two shift forks, and the shift forks rotate to push the bamboo chips to move to the transverse outlet along the gap in the circumferential direction of the sleeve and to come out from the transverse outlet;
the clamping and conveying device is used for clamping bamboo chips in the radial direction and conveying the bamboo chips along the axial direction and comprises an inner ring moving on the axial line, at least two clamping half rings are arranged in the circumferential direction of the inner ring and connected with a clamping power device driving the clamping half rings to move along the radial direction of the inner ring, and the clamping power device is connected with a conveying power device driving the clamping half rings to move axially;
the clamping semi-ring is driven by the clamping power device to clamp the bamboo chips on the inner ring, and the conveying power device drives the clamping power device, the clamped bamboo chips and the inner ring to move along the axial direction.
The beneficial effect of this patent: the original bamboo with the small head end at the front and the large head end at the back axially moves from the back to the front under the pushing of the collision pushing device, and the splitting knife ring gradually splits the original bamboo from the small head end to the original bamboo, so that the original bamboo is split into bamboo chips with equal width in the circumferential direction.
When the bamboo chips arranged in the annular shape pass through the conical cylinder and the compressing semi-rings, the compressing semi-rings compress the bamboo chips on the scraping rings under the driving of the compressing power device, and the scraping rings scrape the inner sections of the bamboo chips.
When the clamping and conveying device is arranged in front of the sequencing device, under the power of the collision pushing device, the bamboo chips which are arranged in a forward annular mode penetrate through the gap between the inner cylinder and the outer cylinder of the sleeve, the front ends of the bamboo chips extend into the space between the inner ring and the clamping half ring, and when the power of the collision pushing device is lost, the clamping half ring clamps the front ends of the bamboo chips between the inner ring and the clamping half ring under the driving of the clamping power device. And then the conveying power device acts to drive the bamboo chips to axially move until the rear ends of the bamboo chips with the inner sections removed come out of the inner section removing device, the two ends of the bamboo chips are positioned between two adjacent shift levers on the two shift forks, at the moment, the conveying power device can stop acting, the bamboo chips do not axially move any more, and the half clamping rings clamp the bamboo chips to release the bamboo chips.
When the clamping conveying device is arranged between the inner section removing device and the sequencing device, bamboo chips extending out of the inner section removing device firstly extend into a gap between the inner ring and the clamping semi-ring and then enter the e-shaped cylinder gap, and when the bamboo chips lose collision thrust, the clamping semi-ring clamps the bamboo chips between the inner ring and the clamping semi-ring under the driving of the clamping power device. Then the conveying power device acts to drive the bamboo chips to move axially until the rear ends of the bamboo chips with the inner sections removed come out of the inner section removing device, meanwhile, the front ends of the bamboo chips move forwards to penetrate through a gap between the inner barrel and the outer barrel of the sleeve, so that the two ends of the bamboo chips are located between two adjacent shift levers on the two shift forks, at the moment, the conveying power device can stop acting, the bamboo chips do not move axially any more, and the clamping half rings loosen the bamboo chips.
After the bamboo chips are loosened by the clamping half rings, the clamping half rings move under the driving of the conveying power device (when the clamping conveying device is arranged in front of the sorting device, the clamping half rings move forwards; when the clamping conveying device is arranged between the inner joint removing device and the sorting device, the clamping half rings move backwards), so that the end parts of the bamboo chips are separated from the clamping half rings in the axial direction. Of course, when the clamping and conveying device is arranged between the inner joint removing device and the sequencing device, if the axial distance between the inner joint removing device and the sequencing device is short, and the clamping half rings move backwards to the limit position (the distance between the clamping half rings and the sequencing device is the largest), the opening distance of the clamping half rings in the radial direction is large, and the opening position and the opening size between the clamping half rings cannot prevent the bamboo chips from moving to the transverse outlet along the gap in the circumferential direction of the sleeve under the pushing of the shifting fork.
At the moment, because the two ends of the bamboo chips are positioned between two adjacent shift levers on the two shift forks, when the shift fork driving device acts, the shift forks can push the bamboo chips to move along the gap in the circumferential direction of the sleeve to the transverse outlet. Because the clearance t between the inner cylinder and the outer cylinder meets the condition that h is less than t and less than 2h, the bamboo chips cannot turn over in the circumferential movement process of the sleeve, only the posture that the tabasheer surfaces face the inner cylinder of the sleeve can be kept in the clearance, and the condition that the tabasheer surfaces face the outer cylinder can not occur, so that the tabasheer surfaces or the tabasheer surfaces of the bamboo chips are sequentially arranged in one direction. The bamboo chips are pushed by the shifting fork to sequentially come out from the transverse outlet of the sleeve.
The process realizes the splitting of the original bamboo into the bamboo chips, removes the inner joints of the bamboo chips, and simultaneously realizes the purpose of sequencing the green surfaces and the yellow surfaces of the bamboo chips towards one direction, thereby avoiding manual sorting and sequencing, and having high automation degree and high operation efficiency.
The shifting fork driving device is positioned in the sleeve, and can prevent the shifting fork driving device from interfering the axial movement and the circumferential movement of the bamboo chips. For example, the shifting fork driving device is arranged inside the inner cylinder and is connected with the shifting fork through an axially extending slender shaft so as to drive the shifting fork to rotate. Of course, the fork driving device belongs to the prior art and is not described again.
As a further improvement of the bamboo chip node removing and sorting device, a plurality of elastic pieces are arranged in the gap, the inner ends of the elastic pieces are connected to the inner cylinder wall in the radial direction of the sleeve, the outer ends of the elastic pieces extend towards the outer cylinder wall to form a tilting shape, and the bamboo chips in the gap are pressed on the outer cylinder wall through the tilting outer ends of the elastic pieces; in the axial direction of the sleeve, the elastic pieces are in an inclined and tilting state, and the inner end close to the inner cylinder wall is behind the outer end close to the outer cylinder wall, so that the bamboo chips can move forwards into the gap from back to front along the axial direction; in the circumferential direction of the sleeve, one side of the elastic sheet close to the transverse outlet of the sleeve is a near side, one side of the elastic sheet far away from the transverse outlet of the sleeve is a far side, and for the far side of one elastic sheet and the near side of the other elastic sheet adjacent to the circumferential direction of the sleeve, the far side of the elastic sheet is closer to the axis of the sleeve, so that the bamboo sheet can move towards the transverse outlet under the pushing of the shifting fork. At the adjacent flexure strip far side of sleeve circumference and flexure strip near side limit, the flexure strip far side limit is more close to the sleeve axis, and the flexure strip near side limit is far away from the sleeve axis, that is to say, the flexure strip that is close to the horizontal export of sleeve can not block the lateral shifting of bamboo chip, and the bamboo chip can smoothly move to the horizontal export.
Preferably, a plurality of groups of elastic pieces are arranged in the sleeve, and the elastic pieces in each group are spirally arranged; the elastic pieces of each group are arranged at intervals in the axial direction of the sleeve. For example, there are three sets of elastic pieces in total, one set at each end and the middle in the axial direction of the sleeve.
Preferably, a plurality of groups of elastic sheets are arranged in the sleeve, the elastic sheets in each group are arranged in a ring shape, and the elastic sheets in each group are arranged at intervals in the axial direction of the sleeve. The sleeve is provided with three groups of elastic sheets in total, and the middle part and two ends of the sleeve in the axial direction are respectively provided with one group.
The purpose of setting up the flexure strip is with the bamboo chip compress tightly on the urceolus for the bamboo chip can laminate with the urceolus wall all the time when removing in the clearance, that is to say, makes the bamboo chip form tangent state with the urceolus wall basically, prevents that bamboo chip and urceolus wall from forming the looks cutting state and fold each other and press, like this, forms butt joint contact between the adjacent bamboo chip of circumference basically, and is more smooth and easy when promoting the bamboo chip and removing.
However, the elastic pieces cannot hinder the bamboo chips from moving forward into the gap from back to front along the axial direction of the sleeve, so that the inner ends of the elastic pieces connected to the inner cylinder wall are behind (close to the rear end of the sleeve), the tilting outer ends extending towards the outer cylinder wall are in front (close to the front end of the sleeve), and an inclined state that the inner ends at the rear part are low (close to the axis of the sleeve) and the outer ends at the front part are high (far away from the axis of the sleeve) is formed, so that the bamboo chips can smoothly move into the gap along the axial direction.
In addition, the elastic sheets cannot hinder the bamboo sheets from moving to the transverse outlet of the sleeve in the gap along the circumferential direction of the sleeve, so that for the far side edge of one elastic sheet and the near side edge of the other elastic sheet which are adjacent in the circumferential direction, the far side edge is closer to the axis of the sleeve than the near side edge, namely, the near side edge is higher (far away from the axis of the sleeve), and the far side edge is lower (close to the axis of the sleeve), so that in two elastic sheets which are adjacent in the circumferential direction of the sleeve, the near side edge is above the far side edge, and the side edges of the elastic sheets which are adjacent in the circumferential direction in each group of elastic sheets form a pressing state, so that the bamboo sheets move along the circumferential direction of the sleeve in the laminating gap, and the bamboo sheets can move smoothly towards the transverse outlet direction from the previous elastic sheet to the next elastic sheet.
The multi-group elastic pieces arranged at intervals in the axial direction of the sleeve can integrally press and attach the bamboo chips warped and bent in the length direction (some bamboo chips are far away from the axis and some bamboo chips are close to the axis at different positions in the axial direction) on the outer cylinder wall to prevent the bamboo chips from warping and bending, so that the bamboo chips are in a straight state and can be guaranteed to smoothly move along the circumferential direction. For example, referring to fig. 11, the warped and bent bamboo strips represented by the dotted lines are pressed and adhered to the outer cylindrical wall of the outer cylinder 42 as a whole by the elastic strips 6 of the three sets of elastic strips 60, and are shown as the bamboo strips 101 in a flat state and shown as solid lines.
As a further improvement of the bamboo chip de-knotting and sorting device, the bamboo chip de-knotting and sorting device is also positioned at the transverse outlet of the sleeve and is used for bearing a support plate of the bamboo chips coming out from the transverse outlet, and the support plate is butted with the side edge of the outer cylinder. The support plate receives bamboo chips coming out from the transverse outlet of the sleeve for subsequent operation.
Preferably, an elastic pressing plate for pressing the bamboo chips coming out from the transverse outlet onto the support plate is arranged at the upper opening position of the transverse outlet of the sleeve.
Preferably, the elastic pressing plates are arranged on the side edge of the inner cylinder at the transverse outlet of the sleeve at intervals. The bamboo chip support plate also comprises a flat plate positioned above the support plate, and the distance between the flat plate and the support plate is slightly larger than the thickness of the bamboo chips.
In order to prevent the bamboo chips coming out from the transverse outlet from turning over and causing the green bamboo surface or the yellow bamboo surface of the bamboo chips not to face one direction, an elastic pressing plate for pressing the bamboo chips on the support plate is arranged. The elastic pressing plate not only facilitates the bamboo chips to move transversely, but also prevents the bamboo chips from overturning on the support plate.
As a further improvement of the bamboo chip knot removing and sorting device, the inner cylinder and the outer cylinder are both in a net shape with holes. The inner cylinder and the outer cylinder with the net structure are convenient for discharging small scraps and the like in the processing process.
As a further improvement of the bamboo chip joint removing and sequencing device, each shifting fork comprises 3-4 shifting rods which are uniformly distributed in the circumferential direction. The number of the deflector rods should not be too large to prevent collision with the bamboo chips moving axially.
As a further improvement of the bamboo chip knot removing and sorting device, the compression half rings are staggered in the axial direction. The interference between the compression semi-rings is prevented when the compression semi-rings compress the bamboo chips.
As a further improvement of the bamboo chip de-knotting and sequencing device, the periphery of the conical cylinder is provided with at least one annular groove. The annular groove can play the effect of scraping to the inner segment of bamboo chip.
As a further improvement of the bamboo chip node removing and sorting device, the pressing half ring is semicircular.
As a further improvement of the bamboo chip joint removing and sequencing device, the pressing power device is a pressing air cylinder.
As a further improvement of the bamboo chip joint removing and sequencing device, the clamping power device is a clamping cylinder.
As a further improvement of the bamboo chip joint removing and sorting device, the conveying power device is a conveying oil cylinder or a mechanical conveying power device comprising a motor.
As a further improvement of the bamboo chip knot removing and sorting device, the clamping half rings are staggered in the axial direction. The interference between the clamping semi-rings is prevented when the clamping semi-rings clamp the bamboo chips.
As a further improvement of the bamboo chip joint removing and sorting device, the inner ring is connected with an inner ring moving power device which drives the inner ring to move along the axis. Preferably, the clamping and conveying device is positioned between the inner-section removing device and a shifting fork in the sequencing device, and the inner ring moving power device is arranged inside a conical cylinder in the inner-section removing device. The inner ring moving power device is an inner ring driving oil cylinder.
The inner ring is connected with the inner ring movement power device, so that the axial position can be adjusted actively, and the inner ring is not only clamped by the clamping half rings and is moved passively along with the axial movement of the clamping half rings. When the clamping and conveying device is positioned between the inner section removing device and the shifting fork at the rear part of the sequencing device, the bamboo chips can be better conveyed, and particularly when the bamboo chips cannot completely pass through the gap of the sleeve only by being pushed by the collision pushing device, the clamping and conveying device can convey the bamboo chips with the inner sections removed in a relay mode, so that the whole bamboo chip can smoothly complete the inner section removing and can pass through the sleeve. The inner ring moving power device is positioned inside the conical cylinder and is used for preventing the inner ring moving power device from interfering the axial moving of the bamboo chips, for example, the inner ring moving power device positioned inside the conical cylinder is connected with the inner ring through a slender rod so as to drive the inner ring to move axially. The inner ring moving power device belongs to the prior art and is not described again.
As a further improvement of the bamboo chip joint removing and sorting device, the gap t between the inner cylinder and the outer cylinder is smaller than the width of the bamboo chips.

The conveying power device acts to drive the bamboo chips to move axially, so that the whole original bamboo is completely split into the annularly arranged bamboo chips through the splitting cutter ring, the inner sections on the bamboo chips are removed through scraping of the scraping ring, meanwhile, the bamboo chips enter the gap in the e-shaped sleeve until the rear ends of the bamboo chips come out of the inner section removing device, the two ends of the bamboo chips are located between two adjacent shift levers on the two shift forks, the conveying power device can stop, the bamboo chips do not move axially any more, the clamping half rings loosen the bamboo chips, then the clamping half rings move under the driving of the conveying power device, and the rear ends of the bamboo chips are separated from the clamping half rings in the axial direction. Then the shifting fork driving device acts, and the shifting fork pushes the bamboo chips to move towards the transverse outlet along the gap in the circumferential direction of the sleeve. Because the gap height t satisfies h < t < 2h and is smaller than the bamboo chip wide band, the bamboo chips can not turn over in the circumferential moving process, only the posture that the tabasheer surface faces the inner cylinder of the sleeve in the gap of the sleeve can be kept, and the condition that the tabasheer surface faces the outer cylinder of the bamboo chips can not occur, so that the tabasheer surface or the tabasheer surface of each bamboo chip can be sequentially arranged in one direction. The bamboo chips are pushed by the shifting fork to sequentially come out from the transverse outlet of the sleeve and enter between the carrier plate and the flat plate.
Example 2:
the bamboo chip de-node sequencing device of the embodiment 2 is mainly different from the sequencing device of the embodiment 1.
The sorting apparatus 4 of example 2 has an additional elastic sheet 6 and an additional elastic pressing plate 7 compared to example 1. Of course, since the elastic pieces 6 are provided in the gap 44 between the inner and outer cylinders in embodiment 2, the height of the gap 44 between the inner and outer cylinders in embodiment 2 may be larger than that in embodiment 1 as long as the distance (distance in the radial direction of the sleeve) j of the elastic pieces 6 in the free state for pressing the outer ends 62 of the bamboo chips against the outer cylinder wall satisfies: j is more than or equal to 0.5h and less than or equal to 0.7h, and the average thickness of the bamboo chips is h. Thus, after the bamboo chips enter the gap 44, the bamboo chips 101 are pressed and attached to the outer cylindrical wall by the elastic sheet 6, and are not turned over. At this time, the height t of the gap 44 between the inner cylinder and the outer cylinder has no special requirement, and t is more than or equal to 2 h.
The different points are explained in detail below.
On the inner cylinder side at the transverse outlet 43 of the sleeve, a plurality of elastic pressing plates 7 are arranged at intervals for pressing the bamboo chips coming out from the transverse outlet on the carrier plate.
The elastic pieces 6 in the gap 44 have 3 groups, each group of elastic pieces is spirally arranged, and a group of elastic pieces 60 are respectively arranged at the middle part and two ends of the sleeve in the axial direction.
In the radial direction of the sleeve, the inner end 61 of the elastic sheet 6 is connected to the inner cylinder wall, the outer end 62 extends towards the outer cylinder wall, and the bamboo chips 101 in the gap are pressed on the outer cylinder wall of the outer cylinder 42 through the outer end 62 of the elastic sheet; in the sleeve axial direction, the elastic sheet inner end 61 is behind the outer end 62, so that the bamboo sheets can advance into the gap from the back in the axial direction; in the circumferential direction of the sleeve, the side of the elastic sheet close to the lateral outlet of the sleeve is a proximal side 64, and the side of the elastic sheet far away from the lateral outlet of the sleeve is a distal side 63. For two circumferentially adjacent panels, the distal edge 63 of the first panel 65 is closer to the sleeve axis 49 than the proximal edge 64 of the second panel 66, i.e. the proximal edge is above the distal edge in two circumferentially adjacent panels of the sleeve, the circumferentially adjacent panels in each set forming a stacked condition such that the bamboo panels can move smoothly in the circumferential direction of the sleeve in the gap in the transverse outlet direction. So that the bamboo chips can move towards the transverse outlet under the pushing of the shifting fork.
When the device in the embodiment 2 is used, because the distance j (the distance in the radial direction of the sleeve) between the outer end 62 of the elastic sheet 6 in the free state and the wall of the outer cylinder for pressing the bamboo sheets satisfies 0.5h and j is not more than 0.7h, after the bamboo sheets enter the gap 44, the bamboo sheets 101 are pressed and attached to the wall of the outer cylinder by the elastic sheet 6, and can not turn over, and only the posture that the tabasheer surface faces the inner cylinder of the sleeve in the gap can be kept, but the tabasheer surface of the bamboo sheets faces the outer cylinder, so that the tabasheer surfaces or the tabasheer surfaces of the bamboo sheets are sequentially arranged in one direction.
Example 3:
referring to fig. 15 to 19, the embodiment 3 is different from the embodiment 2 mainly in the shape of the elastic sheet, the specific connection structure with the inner cylinder, and the arrangement on the inner cylinder, which will be described in detail below.
In the radial direction of the sleeve, the inner end 61 of the elastic sheet 6 is indirectly connected to the inner cylinder wall through the twisting block 8 and the arc plate 9, the arc plate 9 is attached to the circumferential direction of the inner cylinder 41, the rear end of the twisting block 8 is connected with the front end of the arc plate 9, and one end, close to the inner cylinder, of the front end of the twisting block 8 is connected with the inner end 61 of the elastic sheet 6 (the connection of the twisting block and the arc plate is shown in a figure 16 mode). The front end of the twisting block 8 is far away from the inner cylinder, namely, the twisting block 8 is in an inclined state in the axial direction of the sleeve, so that the bamboo chips cannot be prevented from moving forwards from the back to the front along the axial direction of the sleeve to enter a gap of the sleeve; meanwhile, the front end of the twisting block is twisted in the circumferential direction of the inner cylinder to a certain degree relative to the rear end. Referring to fig. 20, the width of the torsion block 8 in the circumferential direction of the sleeve is smaller than that of the arc-shaped plate 9 and the elastic piece 6.
The elastic pieces 6 are 3 groups in total, and the middle part and two ends of the sleeve in the axial direction are respectively provided with one group. The elastic sheets in the same group, the twisting blocks 8 connected to the elastic sheets in the same group and the arc-shaped plates 9 are all annularly arranged in the circumferential direction of the inner cylinder.
In the circumferential direction of the sleeve, the flexible tabs are substantially arcuate, with the side of the flexible tabs adjacent the lateral outlet of the sleeve being a proximal edge 64 and the side of the flexible tabs remote from the lateral outlet of the sleeve being a distal edge 63. For two circumferentially adjacent panels, the distal edge 63 of the first panel 65 is closer to the sleeve axis 49 than the proximal edge 64 of the second panel 66, i.e. the proximal edge is above the distal edge in two circumferentially adjacent panels of the sleeve, the circumferentially adjacent panels in each set forming a stacked condition such that the bamboo panels can move smoothly in the circumferential direction of the sleeve in the gap in the transverse outlet direction. So that the bamboo chips can move towards the transverse outlet under the pushing of the shifting fork.
The beneficial effect of this patent:
the patent designs a bamboo chip node removing and sequencing method which can simultaneously arrange the green surfaces and the yellow surfaces of bamboo chips in sequence after the original bamboo is split.
The conventional bamboo chip processing sequence is as follows: the raw bamboo is cut into bamboo pieces (also called as split pieces) by a cutting machine, and the bamboo pieces are sent into a slicing machine to remove bamboo green and bamboo yellow to obtain the bamboo strip product.
The bamboo chip processing sequence of the invention is as follows: the raw bamboo is cut into bamboo chips by a splitting knife ring, the bamboo chips which are arranged in a ring shape (in the splitting process) remove bamboo joints on the bamboo yellow wall surface through a scraping ring on a conical cylinder under the condition of keeping the mutual positions and the states unchanged, and the bamboo chips enter the gap of the double-layer e-shaped sleeve in the same state and are arranged well; the clamping and conveying device further pulls out all the bamboo chips from the conical cylinder, so that the bamboo chips enter the gap of the double-layer e-shaped sleeve in the same state, the length of the double-layer e-shaped sleeve growing at the two ends of the bamboo chips is basically equal, the bamboo chips in the gap of the e-shaped sleeve are stirred by a shifting fork (shown in figure 4) to move to the transverse outlet end of the e-shaped sleeve, and the bamboo chips are sequentially arranged regularly under the action of an elastic pressure plate at the transverse outlet end and enter the next process or are stored.
This patent can set up the toper drum behind the subdivision sword ring of former bamboo cutting machine (slicer), and the tip of toper drum central axis keeps on a straight line with subdivision sword ring central axis. The diameter of the outer wall of the small end of the conical cylinder is about 10cm larger than the outer diameter of the inner ring of the splitting knife, and because the bamboo chips split by the original bamboo through the ring of the splitting knife are in a conical opening state, the bamboo chips split by the original bamboo can smoothly reach the outer wall of the conical cylinder. The outer periphery of the large end of the conical cylinder is provided with a circular convex scraping ring, two opposite compression half rings capable of performing closing motion are arranged on the outer side of the circular convex scraping ring, the two opposite compression half rings capable of performing simultaneous closing motion are respectively connected with a compression cylinder, and the movable compression half rings can be opened or closed simultaneously under the control of the two compression cylinders. And when the bamboo chips pass through the raised scraping rings on the outer wall of the conical cylinder, bamboo joints on the tabasheer surfaces are scraped off.
The large end of the conical cylinder is opposite to one end of the double-layer e-shaped sleeve, and the central axes of the conical cylinder and the double-layer e-shaped sleeve are kept on the same straight line. The double-layer e-shaped sleeve is arranged to realize that the bamboo chips are transferred from longitudinal (axial) conveying to transverse (circumferential) conveying, and also realize that the bamboo chips are arranged in the uniform direction of the surf green surface or the surf green surface. The double-layer e-shaped sleeve is of a net structure and facilitates discharging processing scraps, the bottom of the circumferential side part of the e-shaped sleeve is open, a sleeve transverse outlet is formed, and bamboo chips are conveniently discharged from the sleeve transverse outlet at the bottom of the e-shaped sleeve. For example 1, the distance between the inner cylinder and the outer cylinder (gap height t) of the double-layer sleeve is generally 12-15mm, is larger than the thickness h (h is generally 7-10 mm) of the bamboo chips after the inner sections are removed, and is smaller than the width of the bamboo chips (generally, the width of the bamboo chips is 22-24 mm), and the gap layer between the inner cylinder and the outer cylinder of the double-layer sleeve is a path for conveying the bamboo chips. The outer diameter of the inner cylinder is basically consistent with that of the scraping ring, so that bamboo chips can smoothly enter the clearance layer of the double-layer sleeve in an annular arrangement under the pressing of the pressing cylinder and the guiding of the conical cylinder, and the size of the clearance between the inner cylinder and the outer cylinder of the e-shaped double-layer sleeve can ensure that the bamboo chips can smoothly move sideways in the clearance but cannot roll.
The clamping and conveying device can be arranged at the front end of the double-layer sleeve, when the front end of the bamboo chip is discharged from the front end of the double-layer sleeve to enter the clamping and conveying device, the clamping half ring firstly clamps the bamboo chip and pulls the bamboo chip to walk for a certain distance along the axial direction after the collision thrust is lost, and the bamboo chip is completely separated from the conical cylinder. The clamping and conveying device consists of a clamping mechanism and a conveying mechanism, wherein the clamping mechanism consists of an inner ring, two clamping semi-rings capable of performing clamping movement and two clamping cylinders; each clamping half ring is correspondingly connected with one clamping cylinder, and the two clamping half rings push the bamboo chips to be tightly pressed on the inner ring under the pressure of the clamping cylinder so as to clamp the bamboo chips. The horizontal movement of the inner ring and the clamping device is completed by a conveying mechanism. The conveying mechanism consists of 3 horizontal rails (a central slide bar and two edge slide bars), a conveying power device and the like; the movable inner ring is fixed on the central slide bar, and the clamping cylinders are respectively arranged on two different edge slide bars. The clamping mechanism and the inner ring are driven to move horizontally along the sliding rod under the action of the conveying power device. Because the original bamboo is changed into the bamboo chips when passing through the splitting knife ring under the action of the impact force of the impact pushing device, the bamboo chips can pass through the splitting knife ring but generally can not pass through the conical cylinder in full length, and because the bamboo chips are subjected to the thrust action of the impact pushing device, the thrust is stopped after reaching the splitting knife ring, even if the original bamboo has backward inertia force, the bamboo chips can not pass through the conical cylinder in full length, so that when the bamboo chips lose the thrust force and the inertia, the bamboo chips need to be pulled out from the conical cylinder by a clamping and conveying device. The clamping and conveying device pulls the bamboo chips which do not pass through the conical cylinder completely away from the large end of the conical cylinder.
The bamboo chips penetrate the sleeve, two ends of the bamboo chips are exposed outside the sleeve, and the middle part of the bamboo chips is arranged in the gap of the e-shaped double-layer sleeve.
The two ends of the double-layer sleeve are provided with shifting forks, the shifting forks consist of 3-4 shifting levers, the two shifting forks can be connected to one shaft, a shifting fork driving device such as a motor drives the rotary shifting forks to rotate, each shifting lever drives a plurality of bamboo chips to transversely (circumferentially) move along the gap of the sleeve in the double-layer sleeve, and the shifting fork is noticed to rotate in the direction of pushing the bamboo chips to transversely move towards the transverse outlet direction of the sleeve along the side direction of the bamboo chips. The bamboo chips entering the gap of the e-shaped double-layer sleeve are shifted to the transverse outlet of the sleeve, the elastic chips in the gap of the double-layer sleeve are arranged in a manner that the bamboo chips cannot roll and be overlapped and can only be arranged side by side, the elastic pressing plate is arranged at the transverse outlet of the tail of the e-shaped sleeve, and when the bamboo chips are shifted to the elastic pressing plate by the shifting fork, the bamboo chips are sequentially arranged in parallel under the action of the elastic pressing plate. In order to ensure that the bamboo chips are not hindered by the clamping and conveying device when coming out of the transverse outlet of the e-shaped sleeve, when the driving lever drives the bamboo chips to move in the gap, the clamping and conveying devices such as the clamping semi-rings can axially move, so that the bamboo chips are separated from the clamping and conveying device.
Because the e-shaped double-layer sleeve is long round, the length of the bamboo chips is longer than that of the double-layer sleeve, the two ends of each bamboo chip can be exposed out of the double-layer sleeve, the shifting forks are rotated at the two ends of the e-shaped double-layer sleeve, the bamboo chips are arranged in the gap layers of the double-layer sleeve, the shifting forks drive the shifting rods to shift the bamboo chips when rotating, and the bamboo chips are driven by the shifting rods to reach the transverse outlet at the tail of the sleeve. Because every driving lever has stirred several bamboo chips, these several bamboo chips may appear the condition of overlapping and pile together when horizontal migration in the double-deck sleeve, so set up 3-4 driving levers, reduce the bamboo chips and appear piling up together when horizontal migration, resistance when also can reduce and fluctuate, set up the elastic sheet in the e type sleeve and suppress every bamboo chip simultaneously, different thickness bamboo chips can both be suppressed by the elastic sheet, make every bamboo chip paste the outer cylinder wall tightly, even there is the phenomenon of piling up to take place, the possibility of piling up is just smaller. As described above, in the embodiment 1, the distance (gap height t) between the inner cylinder and the outer cylinder is 12-15mm, and the width of the normal bamboo chips is 22-24mm, so that the bamboo chips cannot be turned in the sleeve, and because the thicknesses of the bamboo chips produced by different raw bamboos are different, in order to adapt to the gap that the bamboo chips with different thicknesses can pass through the e-shaped cylinder, a larger gap t needs to be arranged, so the possibility that the bamboo chips with thin thicknesses are overlapped together exists. However, if the elastic pieces are arranged in the gap, the elastic pieces press the bamboo pieces against the outer cylinder wall, which is equal to the size of the gap t which is dynamically controlled, and the bamboo pieces are basically impossible to be superposed in thickness, so that the bamboo pieces are led out from the transverse outlet of the sleeve one by one. The reason why the inner cylinder and the outer cylinder of the double-layer sleeve are arranged in a net structure is that when bamboo chips transversely move in a gap layer of the sleeve, the bamboo chips collide with each other, burrs are generated, and the bamboo chips fall down from meshes.
The transverse outlet at the tail part of the e-shaped sleeve is connected with a production conveying line, and the orderly arranged bamboo chips are conveyed to a slicing machine or a special storage device by the conveying line.
