Description

Technical Field

[0001] The invention relates to the field of bamboo product processing, and in particular to a material sorting device and a material sorting method for cutting bamboo strips. Background Art

[0002] Bamboo strips are thin bamboo strips cut into thin strips or strips of bamboo skin of a specific size. These strips are commonly used to weave a variety of bamboo products. They are often used to make the frames or surface decorations of furniture such as bamboo chairs, tables, and beds. These furniture are not only beautiful and elegant, but also lightweight and durable, making them popular with consumers. In agricultural production, bamboo strips are also used to make handles and sheaths for farm tools, increasing their durability and comfort. After being cut by a slitting machine, the bamboo strips need to be transported for subsequent processing. Before transportation, the strips need to be sorted to facilitate transportation and further processing.

[0003] The Chinese patent document with authorization announcement number CN213059246U discloses a material sorting mechanism for bamboo strip woven fabrics after slitting, including a frame, a motor is provided on the frame, and a chain-type circulating clamping component is also provided on the frame. The chain-type circulating clamping component includes a chain, a limit mounting plate, a transmission gear assembly, and a material clamping assembly. The limit mounting plate is provided on the frame, a limit groove is provided on the limit mounting plate, and a guide opening device is also provided on the limit mounting plate. The limit groove and the guide opening device form an annular channel. The motor is connected to the transmission gear assembly, and the transmission gear assembly is engaged with the chain for transmission. The material clamping assembly is fixed on the chain and driven by the chain to rotate cyclically along the annular channel.

[0004] The above-mentioned material sorting device for bamboo strips has the following shortcomings: First, all the bamboo strips need to be cut before sorting, and then the bamboo strips need to be manually fed into the device in batches for sorting. Therefore, a certain amount of preparatory time is required, and the operation is time-consuming and labor-intensive. Second, the main method of sorting is to clamp the ends of the bamboo strips, move them to the same position, and then release the bamboo strips to allow them to fall. If there are too many bamboo strips piled up during the movement, they are easy to slide, and the position of the bamboo strips will deviate during the falling process, and the alignment effect after landing cannot be guaranteed. Third, the bamboo strips need to be manually removed after sorting, and the bamboo strips are easily messed up during the movement, resulting in ineffective material sorting.

[0027] Example 1, as Figure 1-Figure 2As shown, the present invention proposes a material sorting device for slitting bamboo strips, comprising a receiving frame 1, a cutting and sorting frame 2, and a cleaning and sorting frame 3. The receiving frame 1 is adjusted to the discharge port of the bamboo strip slitting machine through a suspension structure, and is used to transfer the slit bamboo strips 4; the cutting and sorting frame 2 is located on the discharge end of the receiving frame 1, and comprises a clamping component 202 and a cutting component 203 and a positioning component 204 respectively located on both sides of the clamping component 202, and the three can be synchronously translated along the feeding direction; wherein the clamping component 202 is provided with a clamping end that can be deformed and rotated, and the clamping end is set to be circular before slitting, and is set to be circular after slitting. It is set to an elliptical shape; the distance between the cutting component 203 and the positioning component 204 is adjustable; the cleaning material sorting rack 3 is located on the discharge end of the cutting and sorting rack 2; the cut bamboo strips 4 are transferred to the cleaning material sorting rack 3 by the movement of the clamping component 202, the cutting component 203 and the positioning component 204 and the rotation of the clamping end; the bamboo strips are aligned by setting an inclined material sorting surface on the cleaning material sorting rack 3, and the bamboo strips 4 are dust-removed and sorted by setting a negative pressure chamber in the cleaning material sorting rack 3.

[0028] Suspended conveying is a highly efficient material handling method that utilizes a suspended conveyor to suspend materials mid-air for transport. The suspension structure in this invention, primarily composed of a traction chain, carriage, and sling, is a common conveying structure and is therefore not shown in the figure. By suspending the docking rack 1 and the cutting and sorting rack 2 overhead, the docking rack 1 can be aligned with the slitting positions of different bamboo strip cutting machines. This also creates a certain height difference with the cleaning and sorting rack 3, allowing the bamboo strips 4 to slide down.

[0029] like Figure 3 As shown, the material receiving frame 1 includes a frame body 101 located between the cutting and sorting frame 2 and the bamboo strip slitting machine; multiple groups of support frames 102 are arranged on the frame body 101 at intervals along the feeding direction; multiple groups of support rods 103 are set on the multiple groups of support frames 102, forming an arc-shaped material receiving surface with the same height as the discharge port of the bamboo strip slitting machine.

[0030] It should be further explained that the support frame 102 is semi-annular; multiple groups of support frames 102 are horizontally mounted on the concave surface of the support frame 102 .

[0031] When the head end of the bamboo passes through the slitting machine, the end of the bamboo strips 4 directly enters the arc-shaped material connection surface. Since the rear end is still being cut, the bamboo strips 4 are pushed by the cutting to become cylindrical and enter the cutting and sorting rack 2 along the arc-shaped material connection surface.

[0032] like Figure 4-Figure 6As shown, the cutting and sorting rack 2 includes a second frame 201 positioned between the receiving rack 1 and the cleaning and sorting rack 3. The second frame 201 is provided with two mounting slots 20101 on either side. The driving member 205 includes mounting blocks 20502 slidably mounted in the corresponding mounting slots 20101. Telescopic cylinders 20501 are mounted on the mounting blocks 20502. The telescopic ends of the two sets of telescopic cylinders 20501 face each other and are connected to respective rotating seats 20504.

[0033] It should be further explained that a motor 1 and a lead screw 1 20503 driven to rotate by the motor 1 are arranged in the installation groove 20101; the installation block 20502 is connected to the lead screw 1 20503 through a thread and moves horizontally along the installation groove 20101.

[0034] It should be further explained that the connecting frame 206 is located on the cylinder body of the telescopic cylinder 20501, and a double-headed bidirectional cylinder 207 is set along the feeding direction.

[0035] It should be further explained that the connecting frame 206 is a "mouth"-shaped structure, the center of which is connected to the cylinder body of the telescopic cylinder 20501 and is penetrated by its telescopic end; the double-headed bidirectional cylinder 207 is respectively arranged on the upper and lower horizontal sections.

[0036] It should be further explained that the clamping assembly 202 is connected to the rotating seats 20504 on both sides and is located between the two sets of connecting frames 206; the cutting assembly 203 and the positioning assembly 204 are connected to the telescopic end of the double-headed bidirectional cylinder 207 to form a "sun" shaped cutting and sorting structure with the clamping assembly 202.

[0037] By rotating screw 1 20503, mounting block 20502 moves horizontally, allowing the cutting and sorting mechanism to move as a whole, transporting the bamboo strips 4 between the receiving rack 1 and the cleaning and sorting rack 3. A double-ended, bidirectional cylinder 207 adjusts the spacing between the cutting assembly 203 and the positioning assembly 204 to match the length of the bamboo strips 4 to be cut. The telescopic end of telescopic cylinder 20501 deforms the clamping end of clamping assembly 202 to adjust the clamping effect. The rotating end of rotating seat 20504 rotates the clamping end of clamping assembly 202, transferring the bamboo strips 4 to the cleaning and sorting rack 3.

[0038] like Figure 5As shown, the clamping assembly 202 includes two groups of clamping seats 20201 respectively connected to the corresponding side rotating seats 20504; two groups of two-section rotating frames 20202 are arranged, one up and one down, rotating between the clamping seats 20201 on both sides, and finally forming a deformable hexagonal clamping structure; the clamping airbag ring 20203 is located in the hexagonal clamping structure and is connected to all six sides; the air pump 20204 is located on the clamping seat 20201, inflating and deflating the clamping airbag ring 20203; the clamping airbag ring 20203 is the clamping end.

[0039] Bamboo is relatively long. In order to improve the efficiency of processing, the present invention arranges for slitting and sorting to be carried out simultaneously. Due to the partial slitting, the bamboo strips 4 entering the material sorting device still maintain a cylindrical shape. At this time, the telescopic cylinder 20501 pushes the two groups of clamping seats 20201 closer together, and the clamping airbag ring 20203 maintains a circular shape under the pull of the hexagonal clamping structure, covering the cylindrical bamboo strips 4. The air pump 20204 inflates to strengthen the clamping force on the bamboo strips 4. When cutting, the telescopic cylinder 20501 pushes the two groups of clamping seats 20201 away from each other, and the clamping airbag ring 20203 becomes an ellipse under the pull of the hexagonal clamping structure, and the cylindrical structure of the bamboo strips 4 is deformed and becomes close to each other. After being inflated and tightened again, the clamping seat 20201 rotates to guide the bundled cut bamboo strips 4 into the cleaning material sorting rack 3.

[0040] like Figure 6 As shown, the cutting assembly 203 includes two mounting frames 20301 mounted on a telescopic rod at one end of a double-headed bidirectional cylinder 207 and arranged on the left and right; the cutting blades 20302 are slidably arranged on the two mounting frames 20301.

[0041] It should be further explained that a mounting cavity 1 is provided on the mounting frame 1 20301; a lead screw 2 driven to rotate by a motor 2 is rotatably provided in the mounting cavity 1; and two sets of cutting knives 20302 are connected to both ends of the lead screw 2 by threads to realize reverse up and down movement.

[0042] It should be further explained that the second screw is provided with reverse threads.

[0043] When the bamboo strips 4 are clamped and in place, the two sets of cutting knives 20302 move relative to each other to cut the cylindrical bamboo strips 4.

[0044] like Figure 6 As shown, the positioning assembly 204 includes two mounting frames 20401 mounted on the telescopic rod at the other end of the double-headed bidirectional cylinder 207 and arranged in two groups, one on the left and one on the right; the positioning plate 20402 is slidably arranged on the two groups of mounting frames 20401, one up and one down.

[0045] It should be further explained that a pressure sensor is provided on the positioning plate 20402 .

[0046] It should be further explained that a mounting cavity 2 is provided on the mounting frame 2 20401; a lead screw 3 driven to rotate by a motor 3 is rotated and provided in the mounting cavity 2; and two sets of positioning plates 20402 are connected to both ends of the lead screw 3 by threads to realize reverse up and down movement.

[0047] It should be further explained that the lead screw 3 is provided with reverse threads.

[0048] When the bamboo strips 4 move to contact with the plate 20402 in place, it can be judged that they are in place. In addition, by moving the plate 20402 in place, the bamboo strips 4 can also be positioned. In particular, the ends of the dispersed bamboo strips 4 after cutting are clamped to assist them in entering the cleaning material handling rack 3.

[0049] like Figure 7-Figure 8 As shown, the cleaning material sorting rack 3 includes a material sorting box 301 located at the discharge end of the cutting material sorting rack 2; the material sorting box 301 is an inclined U-shaped structure, with a negative pressure cavity connected to the negative pressure device 307 arranged inside, the top opening for feeding, an alignment plate 304 arranged at the bottom, and a cleaning port 306 connected to the negative pressure cavity and with a filter screen arranged on the inclined material sorting surface.

[0050] After the bamboo strips 4 are cut and fastened by the clamping airbag ring 20203, the cutting components 203 and the positioning components 204 on both sides are separated, and then the clamping base 20201 is rotated to guide the bundled cut bamboo strips 4 into the sorting box 301. The bamboo strips 4 slide along the inclined sorting surface, and the dust and cut debris on the surface are absorbed and removed, and finally the bottom of the bamboo strips rests on the alignment plate 304.

[0051] It should be further explained that a detachable box plate 305 is provided at the bottom of the material sorting box 301; the garbage in the negative pressure chamber can be collected and removed by regularly removing the box plate 305.

[0052] like Figure 9 As shown, a U-shaped bundling groove 302 is provided on the inclined material sorting surface of the material sorting box 301; an adsorption hole 308 connected to the negative pressure chamber is provided in the bundling groove 302; a storage rack 309 located on one side of the bundling groove 302 is also provided on the material sorting box 301; and a bundling belt 303 is wrapped around the storage rack 309.

[0053] Pull out the strapping belt 303 in advance, make it pass through the strapping groove 302, and be adsorbed and fixed in the strapping groove 302. When all the bamboo strips 4 are aligned, the worker closes the negative pressure device 307, pulls out the strapping belt 303 behind the bamboo strips 4 and can strap it.

[0054] Example 2: This example is based on the material sorting device for cutting bamboo strips described in Example 1, and proposes a material sorting method for cutting bamboo strips. The material sorting steps are as follows:

[0055] S1. Adjust the material receiving rack 1 to the discharge port of the bamboo strip slitting machine through the suspension structure; after the bamboo is slit by the bamboo strip slitting machine, the ends of the first slit bamboo strips 4 first enter the material receiving rack 1. Under the push of the slitting, the bamboo strips 4 become cylindrical and enter the cutting and sorting rack 2 along the curved material receiving surface;

[0056] S2. The distance between the cutting assembly 203 and the positioning assembly 204 is adjusted by the double-headed bidirectional cylinder 207 to match the length of the bamboo strips 4 to be cut; at the same time, the bamboo strips 4 move through the two sets of cutting knives 20302 and through the clamping airbag ring 20203 until they come into contact with the positioning plate 20402, which indicates that they are in position.

[0057] S3. The telescopic cylinder 20501 pushes the two sets of clamping seats 20201 closer together. The clamping airbag ring 20203 maintains a circular shape under the pull of the hexagonal clamping structure, covering the cylindrical bamboo strips 4. At the same time, the air pump 20204 is inflated to clamp the bamboo strips 4.

[0058] S4. The two sets of cutting knives 20302 move relative to each other to cut the cylindrical bamboo strips 4. During the cutting process, as the bamboo strips 4 are cut, the telescopic cylinder 20501 pushes the two sets of clamping seats 20201 away from each other. The clamping airbag ring 20203 becomes elliptical under the pull of the hexagonal clamping structure, and the cylindrical structure of the bamboo strips 4 is deformed and becomes close to each other.

[0059] S5, the cutting and sorting structure moves toward the cleaning and sorting rack 3, the cutting components 203 and the positioning components 204 on both sides are separated, and then the clamping seat 20201 rotates to guide the bundled cut bamboo strips 4 into the sorting box 301;

[0060] S6, the bamboo strips 4 slide along the inclined material processing surface, the dust and broken debris on the surface are absorbed and removed, and finally the bottom is against the alignment plate 304;

[0061] S7, pull out the strapping belt 303 in advance, pass it through the strapping groove 302, and be adsorbed and fixed in the strapping groove 302; when all the bamboo strips 4 are aligned, the worker turns off the negative pressure device 307, pulls out the strapping belt 303 behind the bamboo strips 4 to strap them;

[0062] S8, the cutting and sorting structure moves toward the material receiving rack 1 to sort the subsequently cut bamboo strips 4.

[0063] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
