Abstract
Description
Technical Field
[0001] This utility model relates to a heat setting device, and more particularly to a heat setting device for papermaking blankets applied in the field of processing equipment. Background Technology
[0002] Heat setting equipment for papermaking felts is a specialized device used for heat setting of papermaking felts. It aims to improve the dimensional stability, flatness and other properties of papermaking felts through specific processes and structural designs. Most of these devices only focus on heat setting and lack effective means to deal with defects such as lint and fiber knots on the felt surface.
[0003] Chinese Patent CN103882650A discloses a papermaking felt setting machine, including a motor, a hot oil roller, a tension roller, and a cutting and polishing device. The motor drives the hot oil roller to rotate, and the papermaking felt is tensioned between the hot oil roller and the tension roller. The position of the cutting and polishing device is adjustable. When the cutting and polishing device is adjusted to contact the surface of the papermaking felt, it can cut and polish the surface of the papermaking felt. This invention's papermaking felt setting machine is designed with a cutting and polishing device, employing mechanical polishing to cut and smooth the uneven surface of the papermaking felt. The resulting papermaking felt setting machine is less likely to form felt marks on the paper surface during use, and the paper dewatering is more uniform, improving paper quality. This invention's papermaking felt setting machine has a simple structure, is easy to use, and can remove the hardened surface of the papermaking felt after being heated by the hot oil roller, improving the efficiency of paper dewatering.
[0004] The heat-setting equipment solution for papermaking felts mentioned above generates a large amount of lint and dust when removing the hardened, protruding lint from the papermaking felt after it has been heated by hot oil rollers. If this lint and dust is not cleaned up in time, it will fly around in the workshop environment, affecting not only the working environment but also potentially re-adhere to the papermaking felt, affecting product quality and even causing wear and malfunctions to other parts of the equipment. Utility Model Content
[0005] The technical problem to be solved by this utility model is that when papermaking felt is heated by hot oil rollers, a large amount of lint and dust will be generated when the felt is clumped and raised. If these lint and dust are not cleaned in time, they will fly in the workshop environment, which will not only affect the working environment, but may also re-adhere to the papermaking felt, affecting product quality, and may even cause wear and malfunctions to other parts of the equipment.
[0006] To solve the above problems, this utility model provides a heat-setting device for papermaking felt, including a heat-setting device base, a heat-setting device top frame fixedly connected to the upper end of the heat-setting device base, multiple sets of heat-setting horizontal rollers fixedly connected between the left and right inner walls of the heat-setting device top frame, a papermaking felt body wound around the heat-setting horizontal rollers, a side fixing plate fixedly connected to the left inner wall of the heat-setting device top frame, two sets of horizontally symmetrically arranged electric guide rails fixedly connected to the right end of the side fixing plate, a sliding inner block fixedly connected to the output end of the horizontal electric guide rails, a linkage horizontal plate fixedly connected to the output end of the sliding inner block, multiple lint processors fixedly connected to the end of the linkage horizontal plate away from the horizontal electric guide rails, the multiple lint processors being arranged horizontally, and each lint processor including an outer enclosure frame, with a motor fixedly connected to the inner side wall of the outer enclosure frame.
[0007] In the aforementioned heat setting equipment for papermaking felt, this solution adds a lint treatment step and adapts to an adaptive adjustment structure consisting of a circular working panel, side sliding vertical blocks, side sliding vertical grooves, and force-following springs. The matching pressure is generated by the elastic deformation of the springs to ensure that the adaptable circular working panel and the felt are tightly fitted.
[0008] As a further improvement of this application, an inner rotating spindle is fixedly connected to the output end of the motor, and multiple thickened steel cutting blades are fixedly connected to the outer end of the inner rotating spindle.
[0009] As a further improvement of this application, multiple thickened steel cutting blades are arranged in a ring at equal intervals, and the cutting blades are fixedly connected to the side of the thickened steel cutting blades closest to the papermaking felt body.
[0010] As a further improvement of this application, an adaptive circular working panel is installed at one end of the outer enclosure frame near the papermaking felt body, and the papermaking felt body and the adaptive circular working panel are slidably connected.
[0011] As another improvement of this application, the outer end of the adaptable circular work panel is provided with a number of circular openings, and the number of circular openings are evenly distributed.
[0012] As a further improvement to this application, the adaptable circular working panel is in contact with the outer wall of the papermaking blanket body, and the left and right ends of the outer enclosure frame are symmetrically fixedly connected with side sliding vertical blocks.
[0013] As a further improvement to this application, the left and right inner walls of the adaptable circular working panel are symmetrically provided with side sliding vertical grooves, and a force-following spring is fixedly connected between the side sliding vertical block and the corresponding side sliding vertical groove.
[0014] In summary, this solution utilizes a built-in heating device to ensure the heat-setting cross roller rotates stably and transfers heat evenly, allowing the papermaking felt to be uniformly heated within the top frame of the heat-setting equipment. This lays a solid foundation for subsequent processing. A lint removal stage is added, where a transverse electric guide rail drives a sliding inner block, causing the linkage plate and lint processor to move staggered across the felt surface. This, combined with a high-speed rotating, thickened steel cutting blade within the external enclosure frame, precisely removes lint. Simultaneously, an adaptive adjustment structure consisting of a circular working panel, side sliding vertical blocks, side sliding vertical grooves, and a force-following spring generates matching pressure through spring elastic deformation, ensuring a tight fit between the circular working panel and the felt. This guarantees stable and efficient operation of the lint processor, ultimately achieving high quality, high efficiency, and high stability in felt heat setting and lint removal, thus improving paper production quality.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0025] First implementation method:
[0026] Figures 1-5 A heat-setting device for papermaking felt is shown, comprising a heat-setting device base 1, a heat-setting device top frame 2 fixedly connected to the upper end of the heat-setting device base 1, multiple sets of heat-setting horizontal rollers 3 fixedly connected between the left and right inner walls of the heat-setting device top frame 2, a papermaking felt body 18 wound around the heat-setting horizontal rollers 3, a side fixing plate 4 fixedly connected to the left inner wall of the heat-setting device top frame 2, two sets of horizontally symmetrically arranged electric guide rails 5 fixedly connected to the right end of the side fixing plate 4, a sliding inner block 6 fixedly connected to the output end of the horizontal electric guide rail 5, a linkage horizontal plate 7 fixedly connected to the output end of the sliding inner block 6, multiple lint processors 8 fixedly connected to the end of the linkage horizontal plate 7 away from the horizontal electric guide rail 5, the multiple lint processors 8 being arranged horizontally, and the lint processor 8 including an outer enclosure frame 11, a motor fixedly connected to the inner side wall of the outer enclosure frame 11.
[0027] Figures 1-5 The output end of the motor is fixedly connected to an inner rotating spindle 9. The outer end of the inner rotating spindle 9 is fixedly connected to multiple thickened steel cutting blades 10. The multiple thickened steel cutting blades 10 are arranged in a ring at equal intervals. The side of the thickened steel cutting blades 10 near the papermaking felt body 18 is fixedly connected to a blade 17. The outer enclosure frame 11 near the papermaking felt body 18 is equipped with a matching circular working panel 12. The papermaking felt body 18 and the matching circular working panel 12 are slidably connected. The outer end of the matching circular working panel 12 is provided with several circular openings 13, and the several circular openings 13 are evenly distributed. The matching circular working panel 12 is in contact with the outer side wall of the papermaking felt body 18. The lower sides of the left and right ends of the outer enclosure frame 11 are symmetrically fixedly connected to side sliding vertical blocks 15. The left and right inner walls of the matching circular working panel 12 are symmetrically provided with side sliding vertical grooves 14. The side sliding vertical blocks 15 and the corresponding side sliding vertical grooves 14 are fixedly connected to a force-following spring 16.
[0028] Figures 2-5The papermaking felt body 18 enters the heat-setting equipment, extends into the top frame 2 of the heat-setting equipment, and is wound around multiple sets of heat-setting horizontal rollers 3. The heat-setting horizontal rollers 3 generate heat through a built-in oil-injection heating device, and the heat is evenly transferred to the surface of the papermaking felt body 18 in contact with it. Under the rotation of the heat-setting horizontal rollers 3, the felt gradually completes the heat-setting operation. During this process, the stable rotation and uniform heating of the heat-setting horizontal rollers 3 ensure that the papermaking felt body 18 is heated evenly, laying the foundation for subsequent lint treatment and overall setting effect. When the heat-set papermaking felt body 18 moves to the two transverse electrical... When the guide rails 5 are in contact, the lint treatment process begins. The transverse electric guide rails 5 serve as the power source, and the sliding inner block 6 at the control output end moves horizontally along the guide rail direction. The movement of the sliding inner block 6 drives the linkage horizontal plate 7 to move synchronously, thereby causing multiple lint processors 8 fixed on the linkage horizontal plate 7 to move in a staggered manner on the outer wall of the papermaking felt body 18 to cover all areas of the felt surface and avoid processing dead corners. Each lint processor 8 has a motor installed inside the outer enclosure frame 11. After the motor starts, it drives the inner rotating spindle 9 to rotate at high speed. Multiple thickened steel cutting blades 10 are fixed at the outer end of the inner rotating spindle 9. As the lint processor 8 operates, it undergoes circular motion. The adaptable circular working panel 12 is in close contact with the outer wall of the papermaking felt body 18. Several circular openings 13 at its outer end serve a positioning and guiding function, allowing protruding lint from the felt surface to enter the working range of the thickened steel cutting blade 10. When the protruding lint contacts the blade edge 17 at the outer end of the thickened steel cutting blade 10, the lint is cut off under the cutting force generated by the high-speed rotation of the blade. The structural design of the outer enclosure frame 11 ensures that the cut lint does not overflow and fall back onto the papermaking felt body 18. The cut lint is controlled by the cutting force and the equipment... Under the influence of natural airflow generated during operation, the material moves upward and is temporarily stored in the area above the outer enclosure frame 11. It can then be centrally processed by manual or automatic cleaning devices. In this solution, the heat-setting horizontal roller 3, through its built-in heating device, rotates stably and transfers heat evenly, so that the papermaking felt body 18 is evenly heated in the top frame 2 of the heat-setting equipment, laying a solid foundation for subsequent processing. A lint removal process is added, with the transverse electric guide rail 5 driving the sliding inner block 6, which in turn drives the linkage horizontal plate 7 and the lint processor 8 to move staggered and horizontally on the felt surface. In conjunction with the high-speed rotating thickened steel cutting blade 10 inside the outer enclosure frame 11, the lint is precisely removed.
[0029] Second implementation method:
[0030] Figures 6-7This invention discloses a heat-setting device for papermaking felt. Considering the possible thickness differences in the papermaking felt body 18 from different batches or of different specifications, the device is equipped with an adaptive adjustment structure. Specifically, the adaptable circular working panel 12 and the outer enclosure frame 11 are slidably engaged via a side sliding vertical block 15 and a side sliding vertical groove 14. A force-following spring 16 is connected between the two. When the thickness of the papermaking felt body 18 changes, the adaptable circular working panel 12 is compressed by the felt surface and slides relative to the outer enclosure frame 11 along the side sliding vertical groove 14. During this process, the force-following spring 16 is compressed or stretched, generating matching pressure through the elastic force of the spring. This ensures that no matter how the thickness of the papermaking felt body 18 changes, the adaptable circular working panel 12 can always be tightly fitted to the outside of the felt, thereby ensuring that the felt processor 8 can stably and efficiently cut the felt surface lint, maintaining the stability of the device and the consistency of the processing effect.
[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
