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 refer to bamboos cut into bamboo skins or thin bamboo strips of certain specifications, which are usually used to weave various bamboo products. Bamboo strips are often used to make the frame of furniture or for surface decoration, such as bamboo chairs, bamboo tables, bamboo beds, etc. These furniture are not only beautiful and generous, but also light and durable, and are deeply loved by consumers. In agricultural production, bamboo strips are also used to make tool handles, sheaths and other parts of agricultural tools, which increases the durability and comfort of agricultural tools. After being cut by the slitting machine, the bamboo strips need to be transported for subsequent processing. Before transportation, they need to be sorted for transportation and reprocessing.

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 arranged on the frame, a limit groove is arranged on the limit mounting plate, and a guide opening device is also arranged 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, the transmission gear assembly is meshed with the chain for transmission, and the material clamping assembly is fixed on the chain and driven by the chain to rotate cyclically along the annular channel.

DETAILED DESCRIPTION

[0027] Embodiment 1, as Figure 1-Figure 2As shown, the present invention proposes a material sorting device for slitting bamboo strips, comprising a material receiving frame 1, a cutting material sorting frame 2 and a cleaning material sorting frame 3. The material 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 material sorting frame 2 is located on the discharge end of the material 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 deformable and rotatable clamping end, and the clamping end is set to a circular shape before cutting, and after cutting. It is set to an ellipse; 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 material 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 cleaning material sorting rack 3 is provided with an inclined material sorting surface to align the bamboo strips, and the cleaning material sorting rack 3 is provided with a negative pressure chamber to remove dust from the bamboo strips 4.

[0028] Suspension conveying is an efficient material handling method, which uses a suspension conveyor to suspend materials in the air for transportation. The suspension structure in the present invention is mainly composed of a traction chain, a slide, a hanger, etc., which is a common conveying structure, so it is not drawn in the figure. By suspending the docking rack 1 and the cutting and sorting rack 2 in the air, the material receiving rack 1 is matched with the cutting position of different bamboo strip cutting machines. At the same time, a certain height difference can be formed with the cleaning and sorting rack 3 for 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 that is elevated from 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 cylindrical under the push of the cutting and enter the cutting and sorting rack 2 along the arc-shaped material connection surface.

[0032] like Figure 4-Figure 6As shown in the figure, the cutting and sorting rack 2 includes a second rack body 201 located between the receiving rack 1 and the cleaning and sorting rack 3; on the second rack body 201, there are left and right installation grooves 20101.

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

[0034] It should be further noted that the connecting frame 206 is located on the cylinder body of the telescopic cylinder 20501, and a double-headed two-way cylinder 207 is arranged along the conveying direction.

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

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

[0037] By rotating the first lead screw 20503, the installation block 20502 is driven to move horizontally, and the cutting and sorting structure can move as a whole to transport the bamboo strips 4 between the receiving rack 1 and the cleaning and sorting rack 3. By adjusting the distance between the cutting assembly 203 and the in - place assembly 204 through the double-headed two-way cylinder 207, it is made to match the length of the bamboo strips 4 to be cut. Through the action of the telescopic end of the telescopic cylinder 20501, the clamping ends of the clamping assembly 202 are deformed to adjust the clamping effect. Through the action of the rotating end of the rotating seat 20504, the clamping ends of the clamping assembly 202 rotate to realize the transfer of the bamboo strips 4 to the cleaning and sorting rack 3.

[0038] As 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, which are rotated up and down between the clamping seats 20201 on both sides, and finally form 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, and inflates and deflates 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 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 to be close, 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 is inflated 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, 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 a mounting frame 20301 which is mounted on a telescopic rod at one end of a double-headed bidirectional cylinder 207 and is provided with two groups, one on the left and one on the right; the cutting knife 20302 is slidably provided on the two groups of mounting frames 20301, one up and one down.

[0044] like Figure 6 As shown, the positioning assembly 204 includes two mounting frames 20401 which are mounted on the telescopic rod at the other end of the double-headed bidirectional cylinder 207 and are 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 position plate 20402 .

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

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

In addition, by moving the in-place plate 20402, 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 to enter the cleaning material handling rack 3 later.

[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, and a negative pressure chamber connected to the negative pressure device 307 is arranged inside, the top end is open for feeding, an alignment plate 304 is arranged at the bottom end, and a cleaning port 306 connected to the negative pressure chamber and with a filter is arranged on the inclined material sorting surface.

[0050] After the bamboo strips 4 are cut, they are fastened by the clamping airbag ring 20203, and the cutting components 203 and the positioning components 204 on both sides are separated, and then the clamping seat 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 on the surface and the cut debris are adsorbed and removed, and finally the bottom is against 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.
