Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a pulp fiber setting device. Background Technology

[0002] In the paper towel production and processing industry, the pulp setting process usually involves conveying the pulp attached to the structural network to the setting area by conveying rollers, and then dewatering the pulp.

[0003] However, in the actual production process, the pulp is prone to local accumulation during the conveying process on the structural wire mesh. The existing process lacks effective pretreatment methods. After being squeezed, the accumulated pulp will form paper blanks with uneven thickness, which are difficult to correct in subsequent processing. This results in the finished paper towels having the disadvantages of large differences in thickness and poor feel.

[0004] Therefore, there is an urgent need to develop a pulp fiber setting device that can pre-treat and level the pulp to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing pulp setting devices in practical use, the technical problem to be solved is to provide a pulp fiber setting device with pretreatment and leveling functions.

[0006] The technical solution of this utility model is as follows: a pulp fiber setting device, including a frame, conveying rollers and a structural net. Two conveying rollers are arranged on the top of the frame, and the structural net is connected between the two conveying rollers. Pulp is adsorbed on the outer surface of the structural net. It also includes a positioning seat and a setting component. The positioning seat is arranged in the middle of the frame, and the setting component is arranged on the positioning seat for setting and drying the pulp. The setting component includes a slide, an electric extrusion roller and an electric bidirectional screw. Positioning grooves are opened on the front and rear sides of the positioning seat. A set of vertically adjustable slides is fitted in each positioning groove. An electric extrusion roller is rotatably arranged between two horizontally corresponding slides. An electric bidirectional screw is installed on one side of the positioning seat, and the two vertical slides on one side are threadedly connected to the electric bidirectional screw. By controlling the electric bidirectional screw, the slides are driven to move the electric extrusion rollers on them to adjust the distance between them, which is used to roll flatten the pulp.

[0007] Furthermore, the shaping assembly also includes connecting arms, slide rails, scrapers, and elastic elements. Connecting arms are respectively provided on the two upper slide blocks, and vertically distributed slide rails are respectively connected to the ends of the connecting arms. Scrapers are slidably arranged between the two slide rails. Elastic elements are respectively connected between the two ends of the scraper and the upper inner side of the slide rail, and the lower end surface of the scraper has a smooth structure.

[0008] Furthermore, the shaping component also includes a hot air blower and an air guide hood. A hot air blower is provided on the other side of the positioning seat, and an air guide hood is provided at the air outlet end of the hot air blower, with the air guide hood facing the pulp on the structural network.

[0009] Furthermore, a collection port is provided in the middle of the platform, and the collection port is located directly below the electric extrusion roller.

[0010] Furthermore, the electric extrusion roller has patterned grooves evenly distributed along the axial and circumferential directions.

[0011] Furthermore, it also includes a guide hopper, which is provided inside the collection port.

[0012] The beneficial effects of this utility model are as follows: The pulp on the structural mesh is conveyed to the shaping component by the conveying rollers. The slide is driven by the electric bidirectional screw, which simultaneously realizes the flexible adjustment of the distance between the two electric extrusion rollers and the position movement of the scraper. The scraper initially scrapes the pulp with the conveying of the structural mesh, avoiding local accumulation of pulp that leads to uneven forming thickness. The electric extrusion rollers press and dewater the pulp to achieve rapid forming. The forming pulp is dried by the hot air blower and the air guide hood, which accelerates the dewatering and shaping of the pulp and prevents it from sticking to the structural mesh. Finally, the pulp is continuously and stably shaped, which is conducive to improving the quality of tissue paper production. Attached Figure Description

In the description of the present invention, it should be understood that directional descriptions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] This utility model provides a pulp fiber setting device, see below. Figures 1 to 4 As shown, the device includes a frame 1, conveyor rollers 2, structural mesh 3, positioning seat 4, and a shaping assembly. Two conveyor rollers 2 are mounted on the top of the frame 1, and the structural mesh 3 is connected between the two conveyor rollers 2. Pulp 100 is adsorbed onto the outer surface of the structural mesh 3. A positioning seat 4 with an n-shaped structure is located in the middle of the frame 1. The shaping assembly is mounted on the positioning seat 4 for shaping and drying the pulp 100. The shaping assembly includes a slide 5, an electric pressure roller 6, and an electric bidirectional lead screw 7. Openings are located on the front and rear sides of the positioning seat 4. There are positioning grooves 40, and each positioning groove 40 is fitted with a set of vertically adjustable sliding seats 5. The sliding seats 5 have a T-shaped structure, and an electric extrusion roller 6 is rotatably arranged between two horizontally corresponding sliding seats 5. The electric extrusion roller 6 has patterned grooves 60 evenly distributed along the axial and circumferential directions, which is beneficial for roll forming of the pulp 100 and giving its surface a certain three-dimensional feel. An electric bidirectional lead screw 7 is installed on one side of the positioning seat 4, and the two vertical sliding seats 5 on one side are threadedly connected to the electric bidirectional lead screw 7. The electric bidirectional lead screw 7 drives the slide block 5 to move the electric pressing rollers 6 on it to adjust the spacing, which is used to roll and flatten the pulp 100. The shaping assembly also includes connecting arms 9, slide rails 10, scraper plates 11 and elastic elements 12. Connecting arms 9 are respectively provided on the two slide blocks 5 on the upper side. The ends of the connecting arms 9 are respectively connected to vertically distributed slide rails 10. Scraper plates 11 are slidably arranged between the two slide rails 10. The two ends of the scraper plates 11 are respectively connected to the upper inner side of the slide rails 10 and the elastic elements 12. The elastic element 12 is made of elastic rubber and is used to provide tension to the scraper 11. The lower end face of the scraper 11 is rounded, which is beneficial for the pre-scraping treatment of the pulp 100. The shaping component also includes a hot air blower 8 and an air guide hood 80. The hot air blower 8 is provided on the other side of the positioning seat 4. The air guide hood 80 is provided at the air outlet end of the hot air blower 8. The air guide hood 80 is directly facing the pulp 100 on the structural net 3, which is beneficial for the rapid air drying and dewatering treatment of the extruded pulp 100.

[0021] In addition, a collection port 13 is provided in the middle of the frame 1, and the collection port 13 is located directly below the electric extrusion roller 6; it also includes a guide hopper 14, which is provided inside the collection port 13 to collect the residual liquid of the extruded pulp 100 and avoid waste.

[0022] In the tissue paper production process, the pulp 100 attached to the structural mesh 3 is conveyed to the shaping component by the conveying roller 2. The position of the sliding block 5 is adjusted by controlling the electric bidirectional lead screw 7 to flexibly adjust the distance between the two electric extrusion rollers 6. At the same time, it can drive the scraper 11 to move synchronously. When the lower end face of the scraper 11 contacts the pulp 100 on the structural mesh 3, the continuous conveying of the pulp 100 by the structural mesh 3 enables the lower end face of the scraper 11 to initially level the pulp 100, avoiding local accumulation of the pulp 100 and causing uneven thickness in subsequent forming. In a uniform manner, when the pulp 100 on the structural mesh 3 is conveyed between the two electric extrusion rollers 6, the water contained in the pulp 100 is squeezed out by the rolling action of the two electric extrusion rollers 6, thereby achieving the purpose of rapid molding. Then, by starting the hot air blower 8 and cooperating with the directional airflow of the air guide hood 80, the molded pulp 100 can be dried, which is conducive to accelerating its dewatering and molding, and at the same time can prevent the molded pulp 100 from sticking to the structural mesh 3. In this way, the molding operation of the pulp 100 can be continuously and stably achieved, which is conducive to improving the quality of subsequent paper towel production.

[0023] This shaping device conveys the pulp 100 on the structural mesh 3 to the shaping component via the conveying roller 2. The electric bidirectional screw 7 drives the slide 5, simultaneously adjusting the distance between the two electric extrusion rollers 6 and moving the position of the scraper 11. The scraper 11 initially flattens the pulp 100 as it is conveyed along with the structural mesh 3, preventing uneven thickness caused by local accumulation of pulp 100. The electric extrusion rollers 6 roll and dewater the pulp 100 to achieve rapid shaping. The hot air blower 8, in conjunction with the air guide hood 80, directs the airflow to dry the shaped pulp 100, accelerating dewatering and shaping of the pulp 100 and preventing it from sticking to the structural mesh 3. Ultimately, this achieves continuous and stable shaping of the pulp 100, which is beneficial for improving the quality of tissue paper production.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
