Description

Technical Field

[0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a roller-type bamboo chip milling automatic feeding method and device. Background Art

[0002] The specific operations of the bamboo chip milling process mainly include removing burrs, removing the bamboo green layer, and evenly cutting the bamboo chips in the thickness direction or width direction.

[0003] Generally, the feeding direction of the front end of the bamboo milling process is the length direction of the bamboo. The bamboo passes through the milling station along its length, and the various types of tools arranged in sequence on the latter can complete the above operations at one time. At the back end of the bamboo milling process, multiple thinner or finer bamboo deep-processing materials can be directly obtained.

[0004] Therefore, for the feeding operation of the bamboo chip milling process, it needs to have at least the following three characteristics or functions: First, ensure that the bamboo pieces enter the milling station alone. Otherwise, if two bamboo pieces enter together, it is very easy to damage various tools in the milling station, which is very dangerous. Second, the bamboo piece must have a certain speed when entering the milling station. Otherwise, the bamboo piece may have stopped before its front end hits the power input roller of the milling process. At this time, all subsequent milling operations cannot be carried out and the milling station can only run idle, which is also not allowed to happen.

[0005] For example, a Chinese utility model patent with authorization announcement number CN213440118U and authorization announcement date 2021.06.15 discloses an automatic feeding and fixed-length cutting device for wood, whose structure includes a feeding device and a sawing device. The feeding device includes a feeding frame, a first clamping mechanism, a second clamping mechanism and a conveying mechanism. The first clamping mechanism includes a clamping frame, a clamping cylinder, a clamping guide rod, an upper clamping block and a clamping roller.

[0006] The automatic feeding structure in this utility model patent has the main advantages of: the bamboo is clamped by a clamping device and cut by a cutting device, thereby achieving the effects of automatic feeding and automatic setting of the cutting length during the bamboo cutting process.

[0007] However, the automatic feeding structure still has at least the following shortcomings in actual use, namely: In order to achieve the purpose of individual wood entry at a certain speed, the feeding operation adopts a clamping device to fully clamp the wood and move it together. However, this method requires repeated movement of the entire clamping device, so there are problems such as high energy consumption, low efficiency and high failure rate. Summary of the invention

[0008] The present invention provides a roller-type automatic feeding device for milling bamboo chips, and the technical problem to be solved is how to quickly and efficiently transport bamboo chips one by one to a milling station. The present invention also provides a method for using the device.

[0009] The technical solution adopted by the present invention to solve the above-mentioned problem is: a roller-type automatic feeding device for bamboo chip milling, the structure of which includes a lifting roller unit arranged below the bamboo chip conveyor belt and used to lift the bamboo chips on the bamboo chip conveyor belt, and a power roller unit arranged above the bamboo chip conveyor belt and used to convey the bamboo chips to the milling station by rotating itself and then frictionally driving the bamboo chips.

[0010] A further preferred technical solution is that the lifting roller unit includes a lifting block for connecting to a vertical cylinder, and a V-shaped wheel arranged on the lifting block and used for lifting the bamboo piece upward.

[0011] A further preferred technical solution is that the power roller unit includes a fixed column and a power wheel arranged on the fixed column and used for frictionally driving the bamboo pieces.

[0012] A further preferred technical solution is that the lifting roller unit further comprises a V-shaped positioning plate which is arranged on the lifting block and is used to guide the bamboo pieces to fall onto the V-shaped wheel.

[0013] A further preferred technical solution is that the power roller unit also includes a top plate arranged on the upper end surface of the fixing column, and a motor arranged on the top plate and used for driving the power wheel.

[0014] A further preferred technical solution is that the power roller unit also includes a positioning shaft arranged on the fixed column, and an anti-falling and straightening inclined baffle plate with one end arranged on the positioning shaft and the other end used to block and straighten the rising bamboo pieces.

[0015] A further preferred technical solution is that the power roller unit also includes an anti-stacking inclined baffle, one end of which is arranged on the positioning shaft and the other end blocks the pushing down of the upper bamboo piece so as to separate the two originally stacked bamboo pieces below the visual camera.

[0016] A further preferred technical solution is that: the ends of the anti-dropping and straightening inclined baffles and the anti-stacking inclined baffles are both provided with mounting rings for sleeve-engaging the positioning shaft.

[0017] A further preferred technical solution is that the power roller unit also includes two connecting belts arranged on the top plate and used to suspend the anti-drop straightening inclined baffle and the anti-stacking inclined baffle respectively.

[0018] A method for using a roller-type bamboo chip milling automatic feeding device: the bamboo chip conveyor belt is also provided with a conveying baffle plate, the number of bamboo chips between two adjacent conveying baffle plates is 1 or ≥2, and the lifting roller unit moves upward only after the visual camera detects that the number of bamboo chips between two adjacent conveying baffle plates is 1, thereby lifting the bamboo chip.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: First, the automatic feeding operation of the device only requires lifting and controlling the lifting roller unit and the driving power roller unit, and the weight of the former is relatively small, and the height of the bamboo pieces being lifted only needs to ensure that they leave the bamboo piece conveyor belt, so the overall energy consumption of the operation is relatively low, which has the advantages of simplicity and high efficiency; Second, the jacking feeding operation of the device has the advantage of a controllable switch, which can avoid the harmful phenomenon of two bamboo pieces entering together and damaging the milling station; Third, the power roller unit can also block and prevent the rising bamboo pieces from falling off the lifting roller unit; Fourthly, the power roller unit can also block and separate the two originally stacked bamboo pieces, providing an effective basis for the subsequent bamboo piece quantity detection mechanism, greatly reducing the probability of misjudgment of the above-mentioned bamboo piece quantity detection mechanism, and indirectly protecting the milling station.

DETAILED DESCRIPTION

[0030] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0031] like Figure 1-Figure 9 As shown, a roller-type automatic feeding device for bamboo chip milling includes a lifting roller unit 1 arranged below a bamboo chip conveyor belt a and used to lift bamboo chips b on the bamboo chip conveyor belt a, and a power roller unit 2 arranged above the bamboo chip conveyor belt a and driven by friction through its own rotation to convey bamboo chips b to a milling station c.

[0032] In this embodiment, the automatic feeding device is used in conjunction with a bamboo chip conveying device. The latter's structure includes a bamboo chip conveyor belt a and a conveying baffle e, and the general feeding method of the former is: first lift the bamboo chip b to lift it away from the bamboo chip conveyor belt a, and its upper surface appropriately presses the power roller unit 2, and then turns on the power roller unit 2, or cooperates with the normally open power roller unit 2, so that the bamboo chip b moves along its length direction, enters and completely passes through the milling station c.

[0033] At this point, the complete feeding operation is all over. In this process, the power roller unit 2, which is the upper part of the clamping bamboo piece b, does not need to move horizontally or vertically, which is relatively labor-saving and energy-saving. The lifting height of the bamboo piece b by the lifting roller unit 1 can be set to be relatively small to ensure that the bamboo piece b will not rub against the bamboo piece conveyor belt a during the process of moving away from the bamboo piece b along its length toward the feeding. For example, it can be set to 3-5 cm. So in summary, the automatic feeding device has the advantages of energy saving and high efficiency. The reason is that most of the energy consumption is used to drive the bamboo piece b, rather than moving part of the device itself, which is direct and fast.

[0034] The number of the bamboo conveyor belts a is 2, and the two ends of the bamboo piece b are respectively located on the two bamboo conveyor belts a. The general shape of the bamboo conveyor belt a is an oblong, and the long side direction is horizontal. The bamboo piece b is loaded on one side of the upper belt body of the bamboo conveyor belt a, and the above-mentioned feeding operation is completed before the bamboo piece b falls. Correspondingly, if two bamboo pieces b are accidentally located between two adjacent conveying baffles e, the feeding operation is not performed, and the two bamboo pieces b fall together at the other end of the bamboo conveyor belt a to wait for the subsequent feeding operation of another conveying process.

[0035] In addition, with the upper belt body of the bamboo conveyor belt a as the boundary, the power roller unit 2 and the lifting roller unit 1 are arranged one above and one below. The number of the power roller unit 2 is 1, which is located between the two circles of the bamboo conveyor belt a. The number of the lifting roller units 1 is 1 or 2. When there are 2, one of the lifting roller units 1 is roughly located directly below the power roller unit 2, and the other lifting roller unit 1 is located in the middle or outside of the two circles of the bamboo conveyor belt a. When there is 1 lifting roller unit 1, it can be directly used with one V-shaped lifting plate 3, and the two are lifted and lowered synchronously. The sliding friction between the bamboo piece b and the V-shaped lifting plate 3 will not significantly affect the moving feeding effect of the bamboo piece b.

[0036] The lifting roller unit 1 includes a lifting block 101 for connecting to a vertical cylinder, and a V-shaped wheel 102 disposed on the lifting block 101 and used to lift the bamboo piece b upward.

[0037] In this embodiment, the two circles of bamboo chip conveyor belts a, the milling station c, the visual camera d, and the vertical cylinder are installed together on the main frame of the bamboo chip processing equipment. The vertical cylinder achieves a controllable and adjustable lifting effect through the existing technology.

[0038] Among them, two bearing seats are provided on the upper end surface of the lifting block 101, and the V-shaped wheel 102 is installed on the bearing seat. The V-shaped wheel 102 is a commercially available product, and its main material is ordinary rubber. The V-shaped ring groove on its annular surface can accommodate and fix the bamboo piece b on the left and right, so that after the bamboo piece b is lifted up, it is aligned with the feed port of the milling station c.

[0039] The power roller unit 2 includes a fixed column 201 and a power wheel 202 disposed on the fixed column 201 and used for frictionally driving the bamboo pieces b.

[0040] In this embodiment, the main material of the power wheel 202 is also rubber, in order to obtain a larger friction coefficient with the bamboo piece b, and the power wheel 202 is normally open or controlled to be open.

[0041] The lifting roller unit 1 further includes a V-shaped positioning plate 103 which is arranged on the lifting block 101 and is used to guide the bamboo pieces b to fall onto the V-shaped wheel 102 .

[0042] In this embodiment, the inner bottom surface height of the V-shaped positioning plate 103 is lower than that of the V-shaped wheel 102. The function of the former is that when the V-shaped wheel 102 rises and then docks with the bamboo piece b, the V-shaped positioning plate 103 first centers the bamboo piece b, so that when the V-shaped wheel 102 lifts up the bamboo piece b later, the two must be in a fully aligned state, thereby ensuring the safety and efficiency of the above-mentioned docking action.

[0043] On the other hand, when the V-shaped wheel 102 has been docked and supports the bamboo piece b, the bamboo piece b does not contact the two side surfaces and one inner bottom surface of the V-shaped positioning plate 103, so that the movement operation of the bamboo piece b is more labor-saving and does not increase unnecessary harmful friction resistance.

[0044] Therefore, the V-shaped wheel 102 and the V-shaped positioning plate 103 overlap in the conveying direction of the bamboo piece b, but are arranged on the left and right in the length direction of the bamboo piece b, and the V-shaped positioning plate 103 and the lifting block 101 are welded or screwed.

[0045] The power roller unit 2 further includes a top plate 203 disposed on the upper end surface of the fixing column 201 , and a motor 204 disposed on the top plate 203 and used for driving the power wheel 202 .

[0046] In this embodiment, the top plate 203 is also fixedly connected to the main frame. The motor 204 and the power wheel 202 are provided with a driving belt or a driving chain. The motor 204 is a stepping motor, which is normally open or controlled to be open.

[0047] The power roller unit 2 further comprises a positioning shaft 205 disposed on the fixing column 201, and an anti-dropping and straightening inclined baffle 206 which has one end disposed on the positioning shaft 205 and the other end used to block the rising bamboo piece b.

[0048] In this embodiment, two other bearing seats for mounting the positioning shaft 205 are provided on the side of the fixing column 201. The positioning shaft 205 itself can rotate or not. The front and rear positions of the anti-drop straightening inclined baffle 206 in the conveying direction of the bamboo piece b are also consistent and aligned with the V-shaped wheel 102 and the power wheel 202, that is, they are located on the lifting path of the bamboo piece b.

[0049] Correspondingly, because the V-shaped annular grooves of the V-shaped positioning plate 103 and the V-shaped wheel 102 are both open at the top, when the lifting block 101 rises too fast, the bamboo piece b may first jump up from the lifting roller unit 1, then fall down, and fall back onto the bamboo piece conveyor belt a. This phenomenon has many hazards, including: damaging the power wheel 202, smashing the bamboo piece conveyor belt a, jamming the bamboo piece conveyor belt a, squeezing the lifting block 101 and making it skewed, and breaking the bamboo piece b itself, etc., so it must be avoided. This is the role of the anti-drop straightening inclined baffle 206.

[0050] Among them, the anti-dropping and straightening inclined baffle 206 is in the shape of an inclined straight plate or a two-section folding plate, the end connected to the positioning shaft 205 is the higher end, and the end used to block the bamboo piece b is the lower end, and the height of the lower end is slightly higher than the height of the lowest end of the power wheel 202 itself, to ensure that the anti-dropping and straightening inclined baffle 206 is effective in blocking and preventing the bamboo piece b from bouncing, and will not frictionally hinder the sliding and discharging action of the bamboo piece b. The above-mentioned "slightly higher" height difference can be set to 2 cm, for example.

[0051] On the other hand, the first function of the anti-drop and straightening inclined baffle 206 is to "prevent dropping", and the second function is to "straighten", that is: if the bamboo piece b itself is slightly bent, it will be lifted up by the lifting roller unit 1 and the V-shaped lifting plate 3, and then it can be pressed down appropriately by the anti-drop and straightening inclined baffle 206, so that the bamboo piece b can obtain a certain straightening effect.

[0052] The power roller unit 2 also includes an anti-stacking inclined baffle 207, one end of which is disposed on the positioning shaft 205 and the other end of which blocks the upper bamboo piece b-1 from being pushed down, so as to separate two originally stacked bamboo pieces under the visual camera d.

[0053] In this embodiment, when the bamboo pieces b are transported forward, they sequentially pass through: below the anti-stacking inclined baffle 207 , below the visual camera d , and between the V-shaped wheel 102 and the power wheel 202 .

[0054] When the bamboo pieces b are stacked, the existing common visual cameras d are generally unable to distinguish them from the single bamboo piece b being transported, and thus the subsequent feeding operation to the milling station is also triggered, and the two bamboo pieces b are transported together and pushed into the feed port of the milling station, which is very dangerous and is the role of the anti-stacking inclined baffle 207.

[0055] Correspondingly, the highest end of the anti-stacking inclined baffle 207 is connected to the positioning shaft 205, and the height position of its lowest end coincides with the possible upper bamboo piece b-1, so that the two stacked bamboo pieces can be laid flat. The visual camera d detects downward and can accurately distinguish the effective state of single bamboo conveying and the unexpected state of two bamboo pieces being conveyed together. The latter does not trigger the power roller unit 2, and the two bamboo pieces fall together at the end point of the conveying direction of the bamboo conveyor belt a to wait for the next conveying and loading operation.

[0056] Similar to the shape of the anti-dropping and straightening inclined baffle plate 206, the shape of the anti-stacking inclined baffle plate 207 may also be an inclined straight plate, or a two-section folding plate.

[0057] The ends of the anti-dropping and straightening inclined baffle 206 and the anti-stacking inclined baffle 207 are both provided with mounting rings 208 for sleeve-engaging the positioning shaft 205 .

[0058] In this embodiment, the anti-dropping and straightening inclined baffle 206 and the anti-stacking inclined baffle 207 can be rotated and adjusted in the vertical direction. Because the height of the power wheel 202 is constant and the thickness of the bamboo piece b does not change much, both of them can be simply set to be fixed.

[0059] The advantages of both of the above being set as vertically rotatable are: First, for the anti-dropping and straightening inclined baffle 206, the small impact force caused by the bamboo piece b can be resolved by its own upward rotation action, and does not need to be applied to the connection position between it and the positioning shaft 205, which greatly extends the effective service life of the anti-dropping and straightening inclined baffle 206; Second, the anti-stacking inclined baffle 207 can be adjusted to rotate vertically, so that its blocking action on the upper bamboo piece b-1 is more precise, so that the phenomenon of stacking bamboo pieces can be almost completely avoided, that is, the visual camera d will not make a misjudgment.

[0060] Accordingly, one way to realize the vertically rotatable height adjustment of the anti-dropping and straightening inclined baffles 206 and the anti-stacking inclined baffles 207 is that they are respectively connected to the positioning shaft 205 through the mounting rings 208. Accordingly, the length of the positioning shaft 205 needs to be appropriately larger, thereby leaving enough installation space for the anti-stacking inclined baffles 207.

[0061] The power roller unit 2 further includes two connection belts 209 which are arranged on the top plate 203 and are used to suspend the anti-dropping and straightening inclined baffle 206 and the anti-stacking inclined baffle 207 respectively.

[0062] In this embodiment, after the anti-dropping and straightening inclined baffle 206 and the anti-stacking inclined baffle 207 are set to be vertically rotatable and adjustable, it is necessary to ensure that both will not rotate downward during use. The former may only bounce upward slightly after being hit by the bamboo piece b, and the latter will not move vertically in principle.

[0063] Therefore, the function of the connecting belt 209 is to ensure that: first, the anti-dropping and straightening inclined baffle 206 and the anti-stacking inclined baffle 207 have the function of adjustable lowest point height before use, that is, before the bamboo chip conveying operation starts; second, after the bamboo chip conveying and feeding operation starts, the two will not rotate downward.

[0064] The connecting belt 209 may be a chain, a rope, or the like.

[0065] A method for using a roller-type automatic feeding device for milling bamboo chips, comprising: the bamboo chip conveyor belt a is also provided with a conveying baffle plate e, the number of bamboo chips b between two adjacent conveying baffle plates e is 1 or ≥2, and the lifting roller unit 1 moves upward only after the visual camera d detects that the number of bamboo chips b between two adjacent conveying baffle plates e is 1, thereby lifting the bamboo chip b.

[0066] In this embodiment, the vertical dimension of the conveying baffle e is relatively small, and it is very rare that the number of bamboo pieces between two adjacent conveying baffles e is 3 or even more. However, even if it does happen, the anti-stacking inclined baffle 207 can more easily push down the upper bamboo pieces, and the visual camera d can more easily identify it, so the power roller unit 2 will not be opened by mistake.

[0067] Furthermore, the push-down horizontal plate 211 is also provided at the lowest end of the anti-stacking inclined baffle 207, and its function is: when the number of stacked bamboo pieces is ≥ 3, that is, after the anti-stacking inclined baffle 207 has blocked and pushed down the bamboo pieces above, and multiple bamboo pieces still cannot be spread out in a single layer between the two conveying baffle plates e, the upper bamboo piece b-1 can push the push-down horizontal plate 211, so that the anti-stacking inclined baffle 207 is passively rotated upward. At this time, at least 2 bamboo pieces have been spread out, so the visual camera d will not make a misjudgment. For details, please refer to the attached Fig. 9 .

[0068] Therefore, the ultimate function of the push-down horizontal plate 211 is to prevent a group of large amounts of stacked bamboo pieces that cannot be pushed down and are still in the form of two layers of bamboo pieces from getting stuck or breaking the anti-stacking inclined baffle 207.

[0069] Correspondingly, the push-down horizontal plate 211 is generally in the shape of a triangle or an inverted trapezoid, so as to provide an oblique side or an arc side for the upper bamboo pieces to pass through and push upward.

[0070] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
