Description

Technical Field

[0001] This utility model relates to the field of pulp shearing technology, and in particular to a dust removal shearing device for pulp shearing. Background Technology

[0002] In viscose staple fiber production, the main raw material is pulp. In order to reduce the packaging cost of pulp, a considerable portion of the purchased pulp is rolled into rolls, which can save on pulp packaging costs.

[0003] Existing dust-removing shearing devices for roll pulp shearing suffer from insufficient roll strength, making them prone to breakage and fragmentation during traction. Furthermore, the use of a striking shearing method results in significant vibration and noise, easy loosening and displacement of the blades, and easy deformation of the blade beam, leading to low shearing efficiency and poor mechanical efficiency.

[0004] Existing dust-removing shearing devices for roll pulp shearing generate a large amount of dust during shearing, which flies everywhere. After shearing, a large number of personnel are needed to collect and process the pulp, indicating a low level of mechanization. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient strength of the rolled pulp, easy breakage and fragmentation during traction, high vibration and noise from the slapping shearing method, easy loosening and displacement of the blade, easy deformation of the blade beam, and the generation of a large amount of dust during shearing that flies everywhere, requiring a large number of personnel to collect and sort the pulp after shearing, resulting in a low degree of mechanization. Therefore, this invention proposes a dust removal shearing device for rolling pulp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust-removing shearing device for shearing pulp rolls includes:

[0008] A support base, on the top of which is rotatably mounted a rotating frame, and four rotating disks are rotatably mounted inside the rotating frame;

[0009] A dust collection bin is located on one side of the support base, and a gantry shear is fixedly installed on its top. The cutter of the gantry shear is located above one of the rotating discs.

[0010] Multiple sets of intermittent components with the same structure are respectively set in the support base and four rotating disks. The intermittent components in the support base are used to drive the rotating frame to rotate 90 degrees intermittently, and the components in the rotating disks are used to drive the rotating disks to rotate 90 degrees intermittently.

[0011] The rotating disk is equipped with a clamping mechanism, which includes a rotatably mounted toothed disk that meshes with a rotatably mounted gear. The gear is driven by a second drive motor. The surface of the toothed disk is provided with four push grooves. Each push groove is connected to an L-shaped clamping plate through a connecting rod. The L-shaped clamping plate is slidably connected to a sliding groove on the inner wall of the rotating disk through a slider.

[0012] In one possible design, the intermittent assembly includes a dial and a grooved wheel, the output shaft of the dial being fixedly connected to the rotation shaft of the grooved wheel, the grooved wheel being fixedly mounted on the bottom of the rotating disk, and the dial being fixedly mounted inside the rotating frame and on the side wall of the dust collection bin.

[0013] In one possible design, a support mesh is fixedly installed on the top of the rotating disk, and a connecting groove is provided inside the mesh. The top of the connecting groove is aligned with the grid of the support mesh, and the bottom is connected to the opening at the top of the dust collection bin. A dust cover is fixedly installed inside the dust collection bin, and a fan is installed inside the dust cover. An exhaust window with a filter screen is opened on the side wall of the dust collection bin.

[0014] In one possible design, the gantry shear includes an L-shaped support frame, a drive cylinder, and a blade. The drive cylinder is fixedly mounted on the top of the L-shaped support frame, and the blade is fixedly mounted on the bottom of the output shaft of the drive cylinder. A dust cover is fixedly mounted on the bottom of the gantry shear, and the dust cover is located on both sides of the cutter and has ventilation windows.

[0015] In one possible design, the dust hood is an inverted trumpet-shaped structure with its bottom opening covering the cutting area. The airflow generated by the fan guides the shearing residue into the dust collection bin through the connecting groove. The filter screen uses HEPA high-efficiency filter material.

[0016] In one possible design, the toothed disc is driven by a second drive motor to rotate the gears, which in turn drives the four L-shaped clamping plates to move radially in sync to achieve automatic centering and clamping of the pulp roll. The intermittent assembly achieves 90-degree precise positioning of the rotating frame and the rotating disc through the cooperation of the dial and the grooved wheel.

[0017] In this application, the pulp roll is placed on a support mesh inside the rotating disc, and the pulp roll is placed between four L-shaped clamping plates. By starting the second drive motor, the output shaft of the second drive motor drives the gear to rotate. The gear meshes with the gear disc, thereby rotating the gear disc. The four push grooves inside the gear disc push the connecting rods to move. The four connecting rods correspondingly drive the four L-shaped clamping plates to move closer together to clamp the pulp roll. The first drive motor inside the support base is started, and the output shaft of the first drive motor drives the dial to rotate. The dial drives the grooved wheel to rotate intermittently by 90 degrees. When the grooved wheel rotates, it drives the rotating frame to rotate. The rotating disc containing the pulp roll rotates to the bottom of the gantry shear. The gantry shear cuts vertically through the blades below it. After cutting, the blades rise, and the first drive motor located on one side of the dust collection bin is powered on and started. The output shaft of the first drive motor drives the dial to rotate, and the dial pushes the grooved wheel. The grooved wheel drives the rotating disk to rotate 90 degrees within the rotating frame, thus cutting vertically again through the blades inside the gantry shear. During the cutting process, the dust hood covers the outside of the roll pulp, and at the same time, the fan used to cover the dust hood is started. The airflow generated by the fan carries the residue cut from the roll pulp through the support mesh into the connecting groove. The connecting groove then enters the dust collection bin through the connection port that connects with the dust collection bin. At the same time, the exhaust window on one side of the dust collection bin is used for ventilation.

[0018] Beneficial effects: The dust removal shearing device for rolling pulp shearing described in this utility model achieves precise 90-degree intermittent rotation of the rotating frame and rotating disk through a dual intermittent component design, ensuring that rolling pulp at multiple stations is cut sequentially, thereby improving the degree of automation and cutting accuracy; at the same time, the L-shaped clamping plate automatically centers through gear transmission, ensuring cutting stability and significantly improving production efficiency.

[0019] In this utility model, the dust removal shearing device for rolling pulp shearing has an integrated dust removal system that works in conjunction with a fan and a filter screen. During cutting, the dust removal hood prevents residue from being scattered, and the dust is guided into the dust collection bin through the connecting groove by the fan inside the dust hood, effectively avoiding dust diffusion, improving the working environment, reducing cleaning and maintenance costs, and taking into account both environmental protection and operational health.

[0020] This invention combines intermittent rotation with a dust removal system, achieving a dual improvement in both high-efficiency and precise cutting and environmental optimization. It features a compact structure, high degree of automation, significantly improved production efficiency and operational safety, and is both practical and environmentally friendly.
