Description

Technical Field

[0001] This utility model belongs to the field of bamboo processing technology, and in particular relates to an automatic feeding device for milling bamboo strips using rollers. Background Technology

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

[0003] Generally, the feeding direction at the front end of the bamboo milling process is along the length of the bamboo strip. The bamboo strip passes through the milling station along its entire length, where various cutting tools arranged sequentially complete the aforementioned operations in one go. At the rear end of the bamboo milling process, multiple thinner or finer bamboo strips for further processing can be directly obtained.

[0004] Therefore, the feeding operation of the bamboo strip milling process should have at least the following three characteristics or functions:

[0005] First, ensure that the bamboo strips enter the milling station separately; otherwise, if two bamboo strips enter together, they are very likely to damage the various cutting tools in the milling station, which is extremely dangerous.

[0006] Secondly, the bamboo strips must have a certain speed when entering the milling station. Otherwise, the bamboo strips may stop before they reach the power input rollers of the milling process at their front end. In this case, all subsequent milling operations cannot be carried out, and the milling station can only idle, which is also not allowed.

[0007] For example, Chinese utility model patent with authorization announcement number CN213440118U and authorization announcement date of June 15, 2021, discloses an automatic wood feeding and fixed-length cutting device. Its structure includes a feeding device and a sawing device. The feeding device includes a feeding frame, a first pressing mechanism, a second pressing mechanism and a conveying mechanism. The first pressing mechanism includes a pressing frame, a pressing cylinder, a pressing guide rod, an upper pressing block and a pressing roller.

[0008] The advantages of the automatic feeding structure in this utility model patent are: the bamboo is clamped by a clamping device and cut by a cutting device, which realizes the effect of automatic feeding and automatic setting of cutting length during the bamboo cutting process.

[0009] However, in actual use, this automatic feeding structure still has at least the following shortcomings:

[0010] In order to achieve the goal of allowing the wood to enter individually and at a certain speed, the loading operation uses a clamping device to fully clamp and move the wood. However, this method requires repeated movement of the entire clamping device, resulting in high energy consumption, low efficiency, and high failure rate. Utility Model Content

[0011] This invention provides an automatic feeding device for milling bamboo strips using rollers. The technical problem it aims to solve is how to quickly and efficiently feed bamboo strips one by one to the milling station. This invention also provides a method for using the above-mentioned device.

[0012] The technical solution adopted by this utility model to solve the above problems is: a roller-type automatic feeding device for bamboo chip milling, the structure of which includes a lifting roller unit set below the bamboo chip conveyor belt and used to lift the bamboo chip on the bamboo chip conveyor belt, and a power roller unit set above the bamboo chip conveyor belt and used to feed the bamboo chip to the milling station by rotating itself and thus frictionally driving the bamboo chip.

[0013] A further preferred technical solution is that the lifting roller unit includes a lifting block for connecting a vertical cylinder, and a V-shaped wheel disposed on the lifting block for lifting the bamboo strip upward.

[0014] A further preferred technical solution is that the power roller unit includes a fixed column and a power wheel disposed on the fixed column and used for frictionally driving the bamboo strips.

[0015] A further preferred technical solution is that the lifting roller unit also includes a V-shaped positioning plate disposed on the lifting block and used to guide the bamboo strips to fall onto the V-shaped wheel.

[0016] A further preferred technical solution is that the power roller unit further includes a top plate disposed on the upper end face of the fixed column, and a motor disposed on the top plate for driving the power roller.

[0017] A further preferred technical solution is that the power roller unit further includes a positioning shaft disposed on the fixed column, and an inclined baffle for preventing the bamboo strips from falling and straightening them, with one end disposed on the positioning shaft and the other end used to block and straighten the bamboo strips as they rise.

[0018] A further preferred technical solution is that the power roller unit also includes an anti-overlapping inclined baffle with one end set on the positioning shaft and the other end blocking the upper bamboo strips from falling off, for separating the two bamboo strips that were originally stacked below the visual camera.

[0019] A further preferred technical solution is that: both the anti-falling and anti-stacking inclined baffles and the anti-stacking inclined baffles are provided with mounting rings for fitting the positioning shaft at their ends.

[0020] A further preferred technical solution is that the power roller unit also includes two connecting belts disposed on the top plate and used to suspend the anti-falling and anti-stacking inclined baffle and the anti-stacking inclined baffle, respectively.

[0021] A method of using a roller-type automatic feeding device for milling bamboo strips: The bamboo strip conveyor belt is also provided with conveying baffles. The number of bamboo strips between two adjacent conveying baffles is 1 or ≥2. The lifting roller unit moves upward only after the vision camera detects that the number of bamboo strips between two adjacent conveying baffles is 1, thereby lifting the bamboo strip.

[0022] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0023] First, the automatic feeding operation of this device only requires a lifting control roller unit and a drive power roller unit. The former is relatively small in weight, and the height at which the bamboo strips are lifted only needs to ensure that they leave the bamboo strip conveyor belt. Therefore, the overall energy consumption of this operation is relatively low, and it has the advantages of being simple and efficient.

[0024] Secondly, the device's top-feed operation has the advantage of a controllable switch, which can prevent the harmful phenomenon of two bamboo strips entering and damaging the milling station at the same time.

[0025] Third, the power roller unit can also block and protect the rising bamboo strips from falling off the lifting roller unit;

[0026] Fourth, the power roller unit can also prevent the two bamboo strips that were originally stacked from separating, providing an effective basis for the subsequent bamboo strip quantity detection mechanism, greatly reducing the probability of misjudgment by the bamboo strip quantity detection mechanism and indirectly protecting the milling station.

[0041] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0042] like Figures 1-9 As shown, an automatic feeding device for milling bamboo strips using rollers includes a lifting roller unit 1 located below the bamboo strip conveyor belt a and used to lift bamboo strips b on the bamboo strip conveyor belt a, and a power roller unit 2 located above the bamboo strip conveyor belt a and used to feed bamboo strips b to the milling station c by rotating itself and thus frictionally driving the bamboo strips b.

[0043] In this embodiment, the automatic feeding device is used in conjunction with a bamboo strip conveying device. The latter includes a bamboo strip conveyor belt a and a conveying baffle plate e. The general feeding method of the former is as follows: first, the bamboo strip b is lifted up, so that it is lifted away from the bamboo strip conveyor belt a, and its upper surface is appropriately pressed against the power roller unit 2. Then, the power roller unit 2 is opened, or the normally open power roller unit 2 is used to move the bamboo strip b along its length direction, so that the whole bamboo strip b enters and completely passes through the milling station c.

[0044] At this point, the entire feeding operation is complete. During this process, the power roller unit 2, which clamps the upper part of the bamboo strip b, does not need to move laterally or vertically, which is relatively labor-saving and energy-efficient. The lifting height of the lifting roller unit 1 on the bamboo strip b can be set to a relatively small value, ensuring that the bamboo strip b does not rub against the bamboo strip conveyor belt a as it moves along its length towards the feeder; for example, it can be set to 3-5 cm. Therefore, in summary, this automatic feeding device has the advantages of energy saving and high efficiency. The reason for this is that most of the energy consumption is used to drive the bamboo strip b, rather than moving any part of the device's own mechanism, which is direct and fast.

[0045] The bamboo strip conveyor belt a consists of two loops. Two bamboo strips b are positioned on the two conveyor belts a, respectively. The conveyor belt a is generally oblong in shape, with its long side running horizontally. Bamboo strips b are fed onto one side of the upper layer of the conveyor belt a, and this feeding operation is completed before the bamboo strips b fall. Conversely, if two bamboo strips b accidentally fall together between two adjacent conveyor baffles e, the feeding operation is not performed, and the two bamboo strips b fall together to the other end of the conveyor belt a, awaiting a subsequent feeding operation.

[0046] Furthermore, with the upper layer of the bamboo strip conveyor belt a as the boundary, the power roller unit 2 and the lifting roller unit 1 are arranged one above the other. There is one power roller unit 2, located between two loops of the bamboo strip conveyor belt a. There can be one or two lifting roller units 1. When there are two, one lifting roller unit 1 is generally located directly below the power roller unit 2, and the other lifting roller unit 1 can be located in the middle or on the outside of the two loops of the bamboo strip conveyor belt a. When there is only one lifting roller unit 1, it can be used directly with one V-shaped lifting plate 3, with both lifting synchronously. The sliding friction between the bamboo strip b and the V-shaped lifting plate 3 will not significantly affect the feeding effect of the bamboo strip b.

[0047] The lifting roller unit 1 includes a lifting block 101 for connecting a vertical cylinder, and a V-shaped wheel 102 disposed on the lifting block 101 for lifting the bamboo strip b upward.

[0048] In this embodiment, the two bamboo strip conveyor belts a, the milling station c, the vision camera d, and the vertical cylinder are all mounted on the main frame of the bamboo strip processing equipment. The vertical cylinder achieves a controllable and adjustable lifting effect through existing technology.

[0049] The upper surface of the lifting block 101 is provided with two bearing seats, and the V-shaped wheel 102 is installed on the bearing seats. The V-shaped wheel 102 is a commercially available product, and its main material is ordinary rubber. The V-shaped groove on its annular surface can accommodate and fix the bamboo strip b from left and right, so that after the bamboo strip b is lifted, it is already aligned with the feed port of the milling station c.

[0050] The power roller unit 2 includes a fixed column 201 and a power wheel 202 disposed on the fixed column 201 and used for friction driving of the bamboo strip b.

[0051] In this embodiment, the main body material of the power wheel 202 is also rubber, in order to obtain a larger coefficient of friction with the bamboo strip b. The power wheel 202 is normally open or controlled to open.

[0052] The lifting roller unit 1 also includes a V-shaped positioning plate 103 disposed on the lifting block 101 and used to guide the bamboo strip b to fall onto the V-shaped wheel 102.

[0053] In this embodiment, the inner bottom surface of the V-shaped positioning plate 103 is lower than that of the V-shaped wheel 102. The function of the former is that, during the process of the V-shaped wheel 102 rising and connecting with the bamboo strip b, the V-shaped positioning plate 103 first centers the bamboo strip b, so that when the V-shaped wheel 102 lifts the bamboo strip b, the two are in a fully aligned state, ensuring the safety and efficiency of the above-mentioned connection action.

[0054] On the other hand, when the V-shaped wheel 102 has docked and supported the bamboo strip b, the bamboo strip b does not contact the two sides and one inner bottom surface of the V-shaped positioning plate 103, so as to make the movement of the bamboo strip b more effortless and not increase unnecessary harmful frictional resistance.

[0055] Therefore, the V-shaped wheel 102 and the V-shaped positioning plate 103 are positioned in the conveying direction of the bamboo strip b, but are arranged on the left and right sides in the length direction of the bamboo strip b. The V-shaped positioning plate 103 and the lifting block 101 are welded or screwed together.

[0056] The power roller unit 2 also includes a top plate 203 disposed on the upper surface of the fixed column 201, and a motor 204 disposed on the top plate 203 for driving the power wheel 202.

[0057] In this embodiment, the top plate 203 is also fixed to the main frame. The motor 204 and the drive wheel 202 are provided with drive belts or drive chains. The motor 204 is a stepper motor, which is normally open or controlled to open.

[0058] The power roller unit 2 also includes a positioning shaft 205 disposed on the fixed column 201, and an inclined baffle 206 for preventing the bamboo strip b from falling and pressing down, with one end disposed on the positioning shaft 205 and the other end used to block the rising bamboo strip b.

[0059] In this embodiment, the side of the fixed column 201 is provided with two additional bearing seats for mounting the positioning shaft 205. The positioning shaft 205 itself can be rotated or not. The front and rear positions of the anti-fall and straightening inclined baffle 206 in the bamboo strip b conveying direction are consistent with and aligned with the V-shaped wheel 102 and the power wheel 202, that is, located on the lifting path of the bamboo strip b.

[0060] Correspondingly, since the V-shaped positioning plate 103 and the V-shaped wheel 102 both have open V-shaped grooves, when the lifting block 101 rises too fast, the bamboo strip b may jump off the lifting roller unit 1 and fall back onto the bamboo strip conveyor belt a. This phenomenon has many hazards, including: damaging the power wheel 202, damaging the bamboo strip conveyor belt a, jamming the bamboo strip conveyor belt a, squeezing the lifting block 101 and causing it to tilt, and breaking the bamboo strip b itself. Therefore, it must be avoided. This is the function of the anti-falling and straightening inclined baffle 206.

[0061] The anti-fall and straightening inclined baffle 206 is shaped as an inclined straight plate or a two-section folded plate. One end of it, which is connected to the positioning shaft 205, is the higher end, and the other end, which is used to block the bamboo strip b, is the lower end. The height of the lower end is slightly higher than the height of the lowest point of the power wheel 202 itself, so as to ensure that the anti-fall and straightening inclined baffle 206 effectively blocks and prevents the bamboo strip b from jumping, and does not rub against or hinder the sliding discharge action of the bamboo strip b. The height difference of "slightly higher" can be set to, for example, 2cm.

[0062] On the other hand, the first function of the anti-fall and straightening inclined baffle 206 is to "prevent falling" and the second function is to "straighten". That is, if the bamboo strip b is slightly bent, it can be lifted by the lifting roller unit 1 and the V-shaped lifting plate 3, and then be appropriately pressed down by the anti-fall and straightening inclined baffle 206, so that the bamboo strip b can achieve a certain straightening effect.

[0063] The power roller unit 2 also includes an anti-overlapping inclined baffle 207, which is mounted on the positioning shaft 205 at one end and blocks the upper bamboo strip b-1 from falling at the other end, for separating the two bamboo strips that were originally stacked below the visual camera d.

[0064] In this embodiment, when the bamboo strip b is conveyed forward, it passes in sequence below the anti-stacking inclined baffle 207, below the visual camera d, and between the V-shaped wheel 102 and the power wheel 202.

[0065] When bamboo strips b are stacked, existing common visual cameras d generally cannot distinguish them from single bamboo strips b being transported. Therefore, it will trigger the subsequent feeding operation to the milling station, which will transport and push the two bamboo strips b together into the feed port of the milling station. This is very dangerous, and it is precisely the function of the tilting baffle 207 for preventing stacking.

[0066] Correspondingly, the highest end of the anti-stacking inclined baffle 207 is connected to the positioning shaft 205, and the height of its lowest end coincides with the possible upper bamboo strip b-1. Therefore, the two stacked bamboo strips can be laid flat. The visual camera d detects downwards and can accurately distinguish between the effective state of single-strip conveying and the unexpected state of two strips being conveyed together. In the latter case, the power roller unit 2 is not triggered, and the two bamboo strips fall together at the end of the conveying direction of the bamboo strip conveyor belt a, waiting for the next conveying and feeding operation.

[0067] Similar to the shape of the anti-fall and anti-pressing inclined baffle 206, the shape of the anti-stacking inclined baffle 207 can also be an inclined straight plate or a two-section folded plate.

[0068] Both the anti-fall and anti-stacking inclined baffle 206 and the anti-stacking inclined baffle 207 are provided with mounting rings 208 for fitting the positioning shaft 205 at their ends.

[0069] In this embodiment, the tilt baffle 206 for preventing falling and pressing and the tilt baffle 207 for preventing stacking can be adjusted vertically. Since the height of the power wheel 202 is constant and the thickness of the bamboo strip b does not change much, both of them can be simply set to a fixed type.

[0070] The advantage of setting both of these to be vertically rotatable is:

[0071] First, for the anti-fall-and-press-straight inclined baffle 206, the small impact force caused by the bamboo strip b can be resolved by its own upward rotation, without having to be applied to the connection position between it and the positioning shaft 205, which greatly extends the effective service life of the anti-fall-and-press-straight inclined baffle 206.

[0072] Secondly, regarding the anti-stacking tilt baffle 207, its ability to rotate vertically makes its blocking action on the upper bamboo strip b-1 more precise, thus almost completely avoiding the phenomenon of stacked bamboo strips, meaning that the visual camera d will not misjudge.

[0073] Accordingly, one way to achieve vertically adjustable height for the anti-fall-and-press tilt baffle 206 and the anti-stacking tilt baffle 207 is to have both connected to the positioning shaft 205 via the mounting ring 208. Accordingly, the positioning shaft 205 needs to be of a sufficiently large length to provide enough installation space for the anti-stacking tilt baffle 207.

[0074] The power roller unit 2 also includes two connecting belts 209 disposed on the top plate 203 and used to suspend the anti-fall and anti-stacking inclined baffle 206 and the anti-stacking inclined baffle 207, respectively.

[0075] In this embodiment, after the anti-fall and anti-stacking inclined baffle 206 and the anti-stacking inclined baffle 207 are set to be vertically rotatable and adjustable, it is necessary to ensure that neither of them will rotate downwards during use. The former may only bounce slightly upwards after being hit by the bamboo strip b, while the latter will remain vertically stationary in principle.

[0076] Therefore, the function of the connecting belt 209 is to ensure that: firstly, the inclined baffle 206 for preventing falling and pressing and the inclined baffle 207 for preventing stacking have adjustable minimum height before use, that is, before the bamboo strip conveying operation begins; secondly, after the bamboo strip conveying and feeding operation begins, neither of them will rotate downwards.

[0077] The connecting belt 209 can be a chain, rope, or other similar material.

[0078] A method of using a roller-type automatic feeding device for milling bamboo strips includes: the bamboo strip conveyor belt a is further provided with a conveying baffle plate e, the number of bamboo strips b between two adjacent conveying baffle plates e is 1 or ≥2, and the lifting roller unit 1 moves upward only after the vision camera d detects that the number of bamboo strips b between two adjacent conveying baffle plates e is 1, thereby lifting the bamboo strip b.

[0079] In this embodiment, the vertical dimension of the conveying baffle plate e is relatively small. It is very rare for the number of bamboo strips between two adjacent conveying baffle plates e to be 3 or even more. However, even if it is, the anti-stacking tilting baffle plate 207 is more likely to push the upper bamboo strips off, and the visual camera d is more likely to identify them, so the power roller unit 2 will not be accidentally activated.

[0080] Furthermore, the lowest end of the anti-stacking inclined baffle 207 is also provided with a pushing-down horizontal plate 211. Its function is as follows: when the number of stacked bamboo strips is ≥3, that is, after the anti-stacking inclined baffle 207 has already blocked and pushed down the upper bamboo strips, if multiple bamboo strips still cannot be spread out in a single layer between the two conveying baffles e, then the upper bamboo strips b-1 can push against the pushing-down horizontal plate 211, causing the anti-stacking inclined baffle 207 to passively rotate and tilt upwards. At this time, at least two bamboo strips have been spread out, thus preventing the visual camera d from misjudging. For details, please refer to the appendix. Figure 9 .

[0081] Therefore, the ultimate function of the push-down horizontal plate 211 is to prevent a large number of stacked bamboo strips that cannot be pushed down and remain in the form of two layers of bamboo strips from getting stuck or breaking the anti-stacking inclined baffle 207.

[0082] Correspondingly, the general shape of the push-down horizontal plate 211 is triangular or inverted trapezoidal, in order to provide the upper bamboo strips with a passable, upward-pushing, inclined or curved edge.

[0083] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of this utility model.
