Description

Technical Field

[0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a bamboo chip identification, separation, rough milling and automatic feeding method and equipment. Background Art

[0002] The common existing bamboo chip identification and separation rough milling system mainly consists of a conveyor belt, a visual recognition camera, and a rough milling unit. The visual recognition camera is used to find unqualified bamboo chips, and when the visual recognition camera detects that the qualified bamboo chips continue to be conveyed forward and align with the rough milling unit, the rough milling unit can obtain them, and then perform a series of subsequent milling operations, and finally divide the bamboo chips into multiple pieces, obtaining multiple thinner and / or finer bamboo strips.

[0003] Correspondingly, the above-mentioned word "separation" mainly refers to separating unqualified bamboo pieces from qualified bamboo pieces, and when the former is aligned with the rough milling parts, the above-mentioned acquisition action is not triggered, and the unqualified bamboo pieces directly fall at the end point of the conveying direction of the conveyor belt.

[0004] Therefore, the function of the above-mentioned automatic feeding equipment is mainly to ensure that the bamboo pieces can fall steadily at the starting point of the conveying direction of the conveyor belt to avoid the following phenomena: first, the bamboo pieces bounce up and fall when they fall; second, the bamboo pieces bounce up when they fall, although they do not fall, but they are tilted and located on two non-corresponding conveyor belt push plates.

[0005] The second phenomenon mentioned above may not be detected by the visual recognition camera, and the acquisition action may still be triggered, resulting in the rough milling parts being stuck, which is very dangerous. In addition, it is also possible that the bamboo pieces, which are unstable in themselves, fall before being transported to the position of the visual recognition camera, which will greatly reduce the efficiency of the bamboo piece recognition and separation rough milling system, which also needs to be avoided.

[0006] For example, a Chinese utility model patent with authorization announcement number CN212355551U and authorization announcement date 2021.01.15 discloses a bamboo strip intelligent identification and flipping device, whose structure includes: a frame, a conveyor belt, an L-shaped pushing frame unit, a flip panel unit and an arc-shaped guide plate unit.

[0007] The advantages of the bamboo chip intelligent identification and turning over device in this utility model patent are mainly: the bamboo chip turning over structure is reasonable and effective, the structure itself has high stability, is easy to disassemble and repair, and the turning over operation is simple and quick.

[0008] However, in actual use, the device still has at least the following shortcomings, namely: Its loading position lacks the necessary protective structure for bamboo chip loading, which causes the bamboo chips to easily bounce, fall, and deflect when they fall on its L-shaped pushing frame unit. At this time, the bamboo chips still remaining on its conveyor belt are no longer perpendicular to the conveyor belt, and are no longer aligned with subsequent turning stations, milling stations and other operating positions, making it difficult to perform subsequent bamboo processing operations. Summary of the invention

[0009] The present invention provides a bamboo chip identification, separation and rough milling automatic feeding device, and the technical problem to be solved is: how to achieve a stable drop-type feeding effect at the feeding position of the bamboo chip identification, separation and rough milling system to ensure that the automatic feeding function is sufficiently safe and orderly.

[0010] In addition, the present invention also provides a method for using the automatic feeding device.

[0011] The technical solution adopted by the present invention to solve the above-mentioned problem is: automatic feeding equipment for bamboo chip identification, separation and rough milling, the structure of which includes a lifting chain, and also includes a top plate located above the conveyor belt, an elastic sheet unit arranged on the top plate and used to laterally block the bamboo chips, an anti-drop inclined plate unit arranged below the elastic sheet unit and used to vertically block the bamboo chips, and an active baffle unit arranged on the top plate and slidably placed on the anti-drop inclined plate unit to block the obtained bamboo chips.

[0012] A further preferred technical solution is that the elastic sheet unit includes a transverse adjustment plate arranged on the top plate, and a vertical elastic sheet arranged on the transverse adjustment plate and used for transversely blocking the bamboo sheets.

[0013] A further preferred technical solution is that the elastic sheet unit further includes an inclined reinforcement plate which is arranged on the transverse adjustment plate and is used to connect the vertical elastic sheet.

[0014] A further preferred technical solution is that the anti-fall inclined plate unit includes an inclined plate for supporting the bamboo pieces sliding downward.

[0015] A further preferred technical solution is that the anti-drop inclined plate unit also includes an arc-shaped mounting plate which is arranged at the upper end of the inclined plate, connected to the lifting chain bearing seat, and used to cover the lifting chain shaft.

[0016] A further preferred technical solution is that the anti-fall inclined plate unit further comprises an L-shaped mounting plate, in which a transverse plate is arranged on the inclined plate and a vertical plate is arranged on the top plate, and is used to allow bamboo pieces to pass through.

[0017] A further preferred technical solution is that the active baffle unit includes a vertical mounting plate arranged on the lower surface of the top plate, a transverse cylinder arranged on the vertical mounting plate, and a transverse sliding baffle arranged on the transverse cylinder and located above the conveyor belt and used to block the bamboo pieces from sliding down the inclined plate.

[0018] A further preferred technical solution is that the active baffle unit also includes an inclined baffle plate which is arranged on the vertical mounting plate and is opposite to the inclined direction of the inclined plate and is used to protect the transverse cylinder from impact by blocking bamboo pieces.

[0019] A further preferred technical solution is that the active baffle unit further includes a transverse track plate arranged on the vertical mounting plate, and a limiting sliding block arranged on the side of the transverse sliding baffle and used for engaging the transverse track plate.

[0020] A method for using a bamboo chip identification, separation and rough milling automatic feeding device, comprising: the transverse cylinder performs an extension and retraction operation only after receiving an impact signal of the bamboo chip at the transverse sliding baffle, so as to lower the bamboo chip supported by the inclined plate and the transverse sliding baffle onto the conveyor belt.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects: First, the automatic feeding device has a sufficient and appropriate blocking effect during the falling of bamboo chips, so that the automatic feeding mode of bamboo chips on the conveyor belt is to put them down instead of throwing them out, thus avoiding the harmful phenomenon of bamboo chips bouncing up on the conveyor belt; Second, indirectly, the automatic feeding equipment allows the lifting chain to have a large height difference, so that the lifting chain has sufficient bamboo slices to rise, greatly reducing the occurrence of harmful phenomena such as accidental stacking of two bamboo slices; Third, indirectly, it allows the lifting chain to have a higher running speed, ensuring that the harmful phenomenon of accidental stacking of two bamboo pieces can be further reduced, while not affecting the stable feeding effect of the bamboo pieces on the conveyor belt; Fourth, the original way of transferring bamboo pieces from the lifting chain to the conveyor belt is to throw them down. During this process, the elastic sheet unit can first block the bamboo pieces and reduce their kinetic energy, ensuring that most of the bamboo pieces first fall on the anti-fall inclined plate unit instead of the active baffle unit, thereby providing sufficient anti-impact protection for the electrical structure on the active baffle unit. Fifth, the anti-drop inclined plate unit and the active baffle unit together form a roughly "V-shaped" structure for receiving falling bamboo pieces, ensuring that all bamboo pieces fall within the "V-shaped" structure and cannot fall directly on the conveyor belt, thereby avoiding the occurrence of harmful phenomena such as bamboo pieces bouncing up significantly and the conveyor belt being damaged.

DETAILED DESCRIPTION

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0032] like Figure 1-Figure 8As shown, the automatic feeding equipment for identifying, separating and rough milling bamboo chips comprises a lifting chain 11, a top plate 1 located above the conveyor belt a, an elastic sheet unit 2 arranged on the top plate 1 and used for laterally blocking the bamboo chips b, an anti-drop inclined plate unit 3 arranged below the elastic sheet unit 2 and used for vertically blocking the bamboo chips b, and an active baffle unit 4 arranged on the top plate 1 and slidably placed on the anti-drop inclined plate unit 3 to block the obtained bamboo chips b.

[0033] In this embodiment, the bamboo chip identification and separation rough milling system and the automatic feeding device are part of the entire bamboo processing line. Generally, a whole bamboo with branches and leaves removed is placed at one end of the bamboo processing line, and thin and fine bamboo chips are finally output at the other end for subsequent production of bamboo mats, bamboo baskets and other bamboo products.

[0034] The bamboo pieces b can be transported one by one on or before the lifting chain 11 to ensure that the bamboo pieces b are thrown from the push plate 12 to the elastic sheet unit 2 one by one. Therefore, the lifting chain 11 needs to have a sufficient height difference to ensure that the above-mentioned control operation of transporting one by one has sufficient operation time.

[0035] However, the conveyor belt a and subsequent structures such as the bamboo green / yellow side turning station and the cutting station do not need to be arranged at a higher position. If the height of the above structure is too high, it will affect the stability of its installation and use.

[0036] Therefore, there must be a relatively large height difference between the highest point of the lifting chain 11 and the conveyor belt a. According to the prior art, the bamboo piece b falls directly on the height difference, and it is easy to bounce and fall, and the conveyor belt a is also frequently hit, which greatly shortens the effective service life of the conveyor belt a.

[0037] Therefore, the elastic sheet unit 2 is used to block the bamboo piece b thrown out by the push plate 12 running to the top, or to allow the bamboo piece b to push the elastic sheet unit 2 while being thrown down, thereby also reducing the kinetic energy of the bamboo piece b.

[0038] Afterwards, the lateral distance that the bamboo piece b is thrown out is greatly shortened. Generally, it first falls on the anti-drop inclined plate unit 3, then slides downward to abut against the active baffle unit 4, and finally the active baffle unit 4 moves in the direction away from the anti-drop inclined plate unit 3, and a feeding port is opened between the anti-drop inclined plate unit 3 and the active baffle unit 4, so that the bamboo piece b is placed on the conveyor belt a relatively slowly and with low kinetic energy, so that the entire automatic feeding operation is finally made safe and stable enough to protect the bamboo piece b and the conveyor belt a.

[0039] The elastic sheet unit 2 includes a transverse adjustment plate 201 disposed on the top plate 1 , and a vertical elastic sheet 202 disposed on the transverse adjustment plate 201 and used for transversely blocking the bamboo sheet b.

[0040] In this embodiment, the top plate 1 and the transverse adjustment plate 201 are both made of steel plates, which are screwed together to adjust the transverse distance between the vertical elastic sheet 202 and the highest point of the lifting chain 11, so as to ensure that the vertical elastic sheet 202 has sufficient and appropriate blocking force on the bamboo sheet b.

[0041] Correspondingly, on the vertical plane perpendicular to the lifting chain axis d, the lateral projections of the vertical elastic sheet 202 and the lifting chain 11 may be partially overlapped or appropriately separated.

[0042] In addition, the material of the vertical elastic sheet 202 is an elastic steel sheet, which, together with the anti-drop inclined plate unit 3 and the active baffle unit 4, are all located on the conveying path of the bamboo piece b. The number of the conveyor belt a and the lifting chain 11 are both 2 circles, and the bamboo piece b is roughly aligned in the center of both. Therefore, when the bamboo piece b is automatically fed, both ends of it will be subject to synchronous and symmetrical blocking and protection effects, ensuring that the bamboo piece b is always horizontal.

[0043] The elastic sheet unit 2 further includes an inclined reinforcing plate 203 which is disposed on the lateral adjustment plate 201 and is used to connect the vertical elastic sheet 202 .

[0044] In this embodiment, the inclined reinforcement plate 203 is made of steel plate and is rectangular or L-shaped. Its upper end is hinged to the lateral adjustment plate 201, and its lower end is fixed or blocked to the vertical elastic sheet 202, so that the actual blocking strength of the vertical elastic sheet 202 on the bamboo sheet b is flexibly adjustable.

[0045] Generally, if the relative lower end of the inclined reinforcing plate 203 is lower, the effective elasticity of the vertical elastic sheet 202 is smaller, and vice versa.

[0046] Furthermore, when the speed of the lifting chain 11 is faster, the bamboo piece b may be thrown obliquely upward. At this time, the inclined reinforcement plate 203 made of hard steel plate replaces the vertical elastic piece 202 to withstand the impact force of the bamboo piece b being thrown quickly, thereby protecting the relatively soft and fragile vertical elastic piece 202. This is very efficient and practical.

[0047] The anti-fall inclined plate unit 3 includes an inclined plate 301 for supporting the bamboo pieces b sliding downward.

[0048] In this embodiment, the inclined plate 301 is laterally farther away from the lifting chain 11 than the vertical elastic plate 202, but the inclined plate 301 is still within the operating area of ​​the bamboo piece b, that is, the distance between the two inclined plates 301 is less than the length of the bamboo piece b.

[0049] The function of the inclined plate 301 is to block the falling bamboo piece b and decelerate the sliding bamboo piece b by friction, thereby greatly reducing the kinetic energy of the bamboo piece b and causing it to hit the active baffle unit 4 at a relatively low speed to avoid damaging the active baffle unit 4.

[0050] The anti-fall inclined plate unit 3 further includes an arc-shaped mounting piece 302 which is arranged at the upper end of the inclined plate 301, connected to the lifting chain bearing seat c, and used to cover the lifting chain shaft d.

[0051] In this embodiment, the arc-shaped mounting piece 302 is the first mounting method of the inclined plate 301. Another function of the arc-shaped mounting piece 302 is to cover and protect the shaft body above the lifting chain shaft d to prevent it from being damaged or contaminated by dust, thereby ensuring the long-term and effective operation of the lifting chain 11.

[0052] The anti-fall inclined plate unit 3 further includes an L-shaped mounting plate 303 in which a transverse plate is arranged on the inclined plate 301 and a vertical plate is arranged on the top plate 1 and is used to allow the bamboo pieces b to pass through.

[0053] In this embodiment, the L-shaped mounting plate 303 is the second mounting method of the inclined plate 301. However, it should be noted that the L-shaped mounting plate 303 needs to avoid the running area of ​​the bamboo piece b. Therefore, the vertical plate body part of the L-shaped mounting plate 303 is relatively outside, that is, the distance between the two vertical plate body parts is greater than the length of the bamboo piece b. For details, please refer to the attached Figure 6 .

[0054] The active baffle unit 4 includes a vertical mounting plate 401 arranged on the lower surface of the top plate 1, a transverse cylinder 402 arranged on the vertical mounting plate 401, and a transverse sliding baffle 403 arranged on the transverse cylinder 402 and located above the conveyor belt a and used to block the bamboo pieces b sliding down on the inclined plate 301.

[0055] In this embodiment, also on the vertical plane perpendicular to the lifting chain axis d, the lateral projections of the inclined plate 301 and the lateral sliding baffle 403 have overlapping parts, ensuring that each bamboo piece b will be blocked by the lateral sliding baffle 403 when sliding down.

[0056] The transverse sliding baffle 403 is also located within the moving area of ​​the bamboo pieces b, and the active baffle unit 4 can be located between or outside the two conveyor belts a.

[0057] Specifically, the transverse sliding baffle 403 is generally rectangular in shape, the transverse cylinder 402 is higher than the transverse sliding baffle 403, and a vertical connecting plate is provided between the two to ensure that the transverse sliding baffle 403 can approach or move away from the inclined plate 301 as needed.

[0058] The active baffle unit 4 also includes an inclined baffle plate 404 which is arranged on the vertical mounting plate 401 and is opposite to the inclined direction of the inclined plate 301 and is used to protect the horizontal cylinder 402 from impact by blocking the bamboo piece b.

[0059] In this embodiment, also on the vertical plane perpendicular to the lifting chain axis d, the lateral projections of the inclined plate 301 and the inclined material baffle plate 404 do not overlap, and the overall height of the inclined material baffle plate 404 is higher than the lateral sliding baffle plate 403. Its function is to prevent the bamboo piece b from directly impacting the lateral sliding baffle plate 403, thereby protecting the lateral cylinder 402.

[0060] Correspondingly, after the bamboo piece b pushes past the vertical elastic piece 202, there are mainly three different falling positions: First, the speed of the bamboo piece b after passing over the vertical elastic piece 202 is relatively slow, and the bamboo piece b falls directly onto the inclined plate 301 , which is the most common. Second, the speed of the bamboo piece b after passing over the vertical elastic piece 202 is moderate, and it first falls on the inclined material blocking plate 404 and then falls on the inclined plate 301, which is relatively rare; Third, the speed of the bamboo piece b after passing over the vertical elastic piece 202 is relatively fast, first directly hitting the vertical mounting plate 401, and then falling on the inclined plate 301 or the inclined material blocking plate 404, which is the rarest.

[0061] In order to protect the horizontal cylinder 402, the second and third phenomena mentioned above need to be avoided as much as possible. Therefore, the blocking strength of the vertical elastic sheet 202 on the bamboo sheet b needs to be adjusted to be sufficient and appropriate, so as to increase the occurrence ratio of the first phenomenon mentioned above as much as possible. The active baffle unit 4 further includes a transverse track plate 405 disposed on the vertical mounting plate 401 , and a limiting slider 406 disposed on a side of the transverse sliding baffle 403 and used for engaging with the transverse track plate 405 .

[0062] In this embodiment, the transverse track plate 405 is fixedly connected to the vertical mounting plate 401, the transverse sliding baffle 403 is fixedly connected to the limiting slider 406, and the transverse track plate 405 and the limiting slider 406 are snap-connected, so that: 1. The sliding mode of the transverse sliding baffle 403 is more stable; 2. The impact strength of the transverse cylinder 402 subjected to the bamboo piece b is lower, thereby protecting the transverse cylinder 402 itself.

[0063] A method for using a bamboo chip identification, separation and rough milling automatic feeding device, comprising: the transverse cylinder 402 performs an extension and retraction operation only after receiving an impact signal from a bamboo chip b at the transverse sliding baffle 403, so as to lower the bamboo chip b supported by the inclined plate 301 and the transverse sliding baffle 403 onto the conveyor belt a.

[0064] In this embodiment, a conventional impact sensor is installed on the vertical mounting plate 401 and / or the transverse sliding baffle 403 , and the sensor is connected to and controls the switching action of the transverse cylinder 402 .

[0065] The cylinder shaft of the horizontal cylinder 402 is extended to open an opening with a sufficient width between the inclined plate 301 and the horizontal sliding baffle 403 for lowering the bamboo piece b. The moving speed of the conveyor belt a also matches the opening action of the horizontal cylinder 402, so that the bamboo piece b is lowered between two adjacent partition plates e, and does not fall directly on the partition plates e.

[0066] Therefore, the conveyor belt a can achieve the effect of conveying bamboo chips one by one without falling, ensuring that the subsequent workstations matched on the conveyor belt a can be carried out safely and orderly, and the harmful phenomenon of two bamboo chips b being loaded at the subsequent workstation together will not occur.

[0067] 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.
