Description

Technical Field

[0001] This invention relates to the field of biomass virgin fiber processing technology, specifically to a high-speed, low-damage combing device and method for biomass virgin fibers. Background Technology

[0002] Biomass virgin fibers, as a renewable and biodegradable green material, are increasingly widely used in textiles, papermaking, composite materials, and other fields. During processing, the carding process is a crucial step in determining fiber quality. It requires mechanical action to separate fiber bundles into individual fibers, remove impurities, and straighten the fiber orientation, providing high-quality raw materials for subsequent processing.

[0003] Biomass virgin fiber raw materials are often mixed with impurities such as mud, short fibers, and hard shells. The screening mechanism of existing equipment is mostly a fixed screen, which has low screening efficiency and cannot be linked with the subsequent carding process. The residue of impurities can easily aggravate the wear of carding parts and lead to insufficient purity of the carded fiber. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed, low-damage combing device and method for biomass virgin fibers to solve the problems mentioned in the background art.

A first U-shaped plate is fixedly connected to the bottom of the connecting rod, and a fixed rod is rotatably connected to the inner side of the first U-shaped plate. A first arc-shaped plate is fixedly connected to the front and rear sides of the fixed rod, and a screening plate is fixedly connected to the bottom of the first arc-shaped plate. A second arc-shaped plate is fixedly connected to the top right side of the screening plate, and a linkage rod is fixedly connected to the inner side of the second arc-shaped plate.

[0007] Preferably, there are two slide rods, which are fixedly connected to the left and right sides of the top of the linkage plate, and are slidably connected to the inside of the support frame. The slide rods can limit the movement of the linkage plate, making the linkage plate more stable during the lifting and lowering process.

[0008] Preferably, there are two electric telescopic rods, which are fixedly connected to the front and rear sides of the bottom of the linkage plate, respectively. The electric telescopic rods can drive the second U-shaped plate and the rotating plate to move downward.

A vertical rod is fixedly connected to the left side of the connecting plate, and an insert plate is rotatably connected to the periphery of the vertical rod.

[0010] Preferably, the inner side of the card plate has a slot corresponding to the position of the insert plate, and the insert plate is inserted into the slot. By using the card plate and the insert plate together, the dust collection drawer is not easy to slide out when the screening box is in use.

[0011] Preferably, the combing mechanism includes a support frame, which is fixedly connected to the top of the conveyor table. A second hydraulic cylinder is fixedly connected to the top of the support frame, and a lifting seat is fixedly connected to the bottom of the second hydraulic cylinder.

[0013] The operation method of the high-speed, low-damage combing device for biomass virgin fibers includes the following steps:

[0014] S1. Raw material screening

[0015] The biomass virgin fiber is placed inside the screening box. The first hydraulic cylinder drives the linkage plate, connecting rod and electric telescopic rod to move up and down. The connecting rod drives the first arc plate and fixed rod to move up and down through the first U-shaped plate. The electric telescopic rod drives the second U-shaped plate, rotating plate, linkage rod and second arc plate to move up and down. The first arc plate and the second arc plate drive the screening plate to move up and down, so that the screening plate can screen the biomass virgin fiber raw material.

[0016] S2, Principle of material discharge

[0017] When it is necessary to discharge the screened biomass virgin fiber raw material, the electric telescopic rod drives the second U-shaped plate and the rotating plate to move downward, so that the rotating plate drives the second arc plate to move downward through the linkage rod, so that the second arc plate pushes the screening plate to rotate downward, allowing the biomass virgin fiber raw material on the top of the screening plate to slide down to the top of the conveyor table.

[0018] S3, Dust Collection Treatment

[0019] After the screened impurities fall into the dust collection drawer, the staff reverses the rotating plate to move it away from the inside of the U-shaped plate. The staff then pulls the pull plate to move the dust collection drawer, allowing it to slide from the inside of the screening box and thus process the impurities inside.

[0020] S4. Raw Material Sorting

[0021] The second hydraulic cylinder drives the lifting seat, drive motor and carding roller to rise and fall, so that the carding roller moves to the appropriate position. The operator turns on the drive motor, so that the drive motor drives the carding roller to rotate, so that the carding roller can card the biomass virgin fiber raw material conveyed on the top of the conveyor.

[0024] 2. In the high-speed, low-damage combing device and method for biomass virgin fibers, in the dust collection mechanism, the operator reverses the rotation plate to move it away from the inner side of the U-shaped plate, and then pulls the pull plate to move the dust collection tray, allowing it to slide from the inside of the screening box, so that the operator can process the impurities inside the dust collection tray.

[0025] 3.

[0046] The operation method of the high-speed, low-damage combing device for biomass virgin fibers includes the following steps:

[0047] S1. Raw material screening

[0048] The biomass virgin fiber is placed inside the screening box 3. The first hydraulic cylinder 43 drives the linkage plate 45, the connecting rod 41 and the electric telescopic rod 46 to move up and down. The connecting rod 41 drives the first arc plate 49 and the fixed rod 47 to move up and down through the first U-shaped plate 48. The electric telescopic rod 46 drives the second U-shaped plate 402, the rotating plate 403, the linkage rod 405 and the second arc plate 404 to move up and down. The first arc plate 49 and the second arc plate 404 drive the screening plate 401 to move up and down, so that the screening plate 401 can screen the biomass virgin fiber raw material.

[0049] S2, Principle of material discharge

[0050] When it is necessary to discharge the screened biomass virgin fiber raw material, the electric telescopic rod 46 drives the second U-shaped plate 402 and the rotating plate 403 to move downward, so that the rotating plate 403 drives the second arc plate 404 to move downward through the linkage rod 405, so that the second arc plate 404 pushes the screening plate 401 to rotate downward, so that the biomass virgin fiber raw material on the top of the screening plate 401 can slide down to the top of the conveyor table 1.

[0051] S3, Dust Collection Treatment

[0052] After the screened impurities fall into the dust collection tray 21, the staff reverses the rotating plate 403 to move it away from the inside of the U-shaped plate. The staff then pulls the pull plate 25 to move the dust collection tray 21, allowing it to slide from the inside of the screening box 3, so that the staff can process the impurities inside the dust collection tray 21.

[0053] S4. Raw Material Sorting

[0054] The second hydraulic cylinder 56 drives the lifting seat 54, drive motor 53 and carding roller 52 to rise and fall, so that the carding roller 52 moves to a suitable position. The operator turns on the drive motor 53, so that the drive motor 53 drives the carding roller 52 to rotate, so that the carding roller 52 can card the biomass virgin fiber raw material conveyed on the top of the conveyor table 1.

[0055] In actual operation, when this device is used, the biomass virgin fiber is put into the screening box 3. The first hydraulic cylinder 43 drives the linkage plate 45, the connecting rod 41 and the electric telescopic rod 46 to move up and down. The connecting rod 41 drives the first arc plate 49 and the fixed rod 47 to move up and down through the first U-shaped plate 48. The electric telescopic rod 46 drives the second U-shaped plate 402, the rotating plate 403, the linkage rod 405 and the second arc plate 404 to move up and down. The first arc plate 49 and the second arc plate 404 drive the screening plate 401 to move up and down, so that the screening plate 401 can screen the biomass virgin fiber raw material. The screened impurities fall into the dust collection drawer 21.

[0056] When the screened biomass virgin fiber raw material needs to be discharged, the electric telescopic rod 46 drives the second U-shaped plate 402 and the rotating plate 403 to move downward. The rotating plate 403 drives the second arc plate 404 to move downward through the linkage rod 405. The second arc plate 404 pushes the screening plate 401 to rotate downward, so that the biomass virgin fiber raw material on the top of the screening plate 401 can slide down to the top of the conveyor table 1. The second hydraulic cylinder 56 drives the lifting seat 54, the drive motor 53 and the carding roller 52 to move up and down, so that the carding roller 52 moves to the appropriate position. The operator turns on the drive motor 53, so that the drive motor 53 drives the carding roller 52 to rotate, so that the carding roller 52 can card the biomass virgin fiber raw material conveyed on the top of the conveyor table 1.

[0057] When it is necessary to clean the impurities inside the dust collection tray 21, the operator reverses the rotation plate 403 to move it away from the inside of the U-shaped plate. The operator then pulls the pull plate 25, which moves the dust collection tray 21 so that it can slide from the inside of the screening box 3, allowing the operator to process the impurities inside the dust collection tray 21.
