Description

Technical Field

[0001] This utility model relates to the technical field of filter paper processing equipment, and specifically to a filter paper heating and forming device. Background Technology

[0002] Filter paper is a fibrous product that uses numerous tiny pores on its surface to perform filtration, achieving solid-liquid separation. During filter paper production, the headbox-produced filter paper contains a large amount of moisture and needs to be dried. Current technology uses multiple heated rollers to convey the filter paper for drying (to ensure drying efficiency, the heated rollers rotate slowly and the temperature is not too high). The heated rollers are driven by motors, with each roller corresponding to a separate motor. This minimizes structural complexity, facilitates maintenance, and minimizes transmission efficiency errors between the rollers, which is beneficial for filter paper transport. However, when one motor fails, the corresponding heated roller stops rotating. This causes the rolling friction between the filter paper and the heated roller to change to sliding friction as the paper passes over it. This not only reduces the heating and drying effect at this point but also increases the resistance experienced by the filter paper, making it prone to breakage. Utility Model Content

[0003] The purpose of this invention is to provide a filter paper heating and forming device to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter paper heating and forming device, comprising: a mounting frame, a heating roller rotatably mounted on the mounting frame, an inner ratchet fixedly connected to one end of the heating roller, a motor mounted on the mounting frame, the output shaft of the motor being connected to the heating roller via a ratchet mechanism, the ratchet mechanism including a ring, a ring fixedly sleeved on the output shaft of the motor, two mounting grooves symmetrically opened on the ring, a pawl rotatably mounted in the mounting groove for cooperating with the inner ratchet, the pawl being connected to the inner wall of the mounting groove via a torsion spring.

[0005] Furthermore, the mounting frame has two rows of heating rollers arranged at equal intervals, with each heating roller in the upper row located above the two heating rollers in the lower row. Filter paper is wrapped around the heating rollers in both rows, and the ratchet mechanism connected to the heating rollers in both rows has ratchet pawls in opposite directions.

[0006] Furthermore, a rectangular frame is fixedly connected to the mounting frame, and a mounting base is fixedly connected inside the rectangular frame. The two ends of the heating roller are connected to the mounting base through bearings.

[0007] Furthermore, a crossbar is fixedly connected to each side of the middle part of the mounting frame, and multiple round rods are arranged between the two crossbars. A scraper is fixedly connected to the round rod, and the scraper is in contact with the surface of the heating roller.

[0008] Furthermore, a rotating shaft is fixedly connected inside the mounting groove, the pawl is rotatably disposed on the outside of the rotating shaft, the torsion spring is sleeved on the outside of the rotating shaft, and one end of the torsion spring is inserted into the inner wall of the mounting groove, while the other end of the torsion spring is inserted into the pawl.

[0009] Furthermore, the motor is mounted on a mounting bracket.

[0010] The filter paper heating and forming device provided by this utility model has the following beneficial effects as described above:

[0011] This invention adds a ratchet mechanism at the connection point between the motor output shaft and the heating roller. When the motor is damaged, the motor output shaft and the heating roller are not locked together, which avoids the filter paper sliding and rubbing when passing the heating roller corresponding to the damaged motor. This ensures the heating effect of the heating roller and reduces the possibility of filter paper breakage.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0022] Please see Figures 1-4 A filter paper heating and forming device includes: a mounting frame 1, a heating roller 2 rotatably mounted on the mounting frame 1, an inner ratchet 6 fixedly connected to one end of the heating roller 2, a motor 3 mounted on the mounting frame 1, the output shaft of the motor 3 being connected to the heating roller 2 via a ratchet mechanism, the ratchet mechanism including a ring 7, the output shaft of the motor 3 being fixedly sleeved with the ring 7, two mounting grooves 71 being symmetrically opened on the ring 7, a pawl 72 rotatably mounted in the mounting groove 71 to cooperate with the inner ratchet 6, the pawl 72 being connected to the inner wall of the mounting groove 71 via a torsion spring 73.

[0023] For details, please refer to Figure 3 The output shaft of motor 3 drives ring 7 to rotate counterclockwise, which in turn causes pawl 72 to engage with the inner teeth of inner ratchet 6, thereby driving inner ratchet 6 to rotate synchronously. This enables motor 3 to drive heating roller 2 to rotate. When motor 3 fails and cannot provide power, the two adjacent heating rollers 2 drive filter paper 8 to move. The tension of filter paper 8 allows the heating roller 2 corresponding to the failed motor 3 to continue rotating. During this period, inner ratchet 6 rotates counterclockwise with heating roller 2. The inner teeth of inner ratchet 6 press against the back of pawl 72 to overcome the torque force of torsion spring 73 and rotate, so that pawl 72 no longer obstructs the rotation of heating roller 2.

[0024] Furthermore, two rows of heating rollers 2 are arranged at equal intervals within the mounting frame 1. Each heating roller 2 in the upper row is positioned above the two heating rollers 2 in the lower row. Filter paper 8 is wrapped around both rows of heating rollers 2. The ratchet mechanism connected to the upper and lower rows of heating rollers 2 has ratchet and pawl directions opposite. Because the upper and lower rows of heating rollers 2 rotate in opposite directions, it is necessary to adjust the arrangement of the ratchet and pawl inside the ratchet structure to ensure that the ratchet and pawl are used in the correct direction. (Refer to...) Figure 1 It can be seen that the inner side of the filter paper 8 is heated by the upper row of heating rollers 2 to remove moisture, and the outer side of the filter paper 8 is heated by the lower row of heating rollers 2 to remove moisture.

[0025] Furthermore, a rectangular frame 11 is fixedly connected to the mounting frame 1, and a mounting base 12 is fixedly connected inside the rectangular frame 11. Both ends of the heating roller 2 are connected to the mounting base 12 via bearings. The inner ring of the bearing is fixedly sleeved on the outer end of the heating roller 2, and the outer ring of the bearing is embedded in the mounting base 12. A crossbar 13 is fixedly connected to each side of the middle section of the mounting frame 1. Multiple round rods 4 are arranged between the two crossbars 13. Both ends of the round rods 4 are fixedly connected to the crossbars 13. A scraper 41 is fixedly connected to the round rod 4. The inclination direction of the scraper 41 depends on the rotation direction of the heating roller 2, i.e., the scraper 41 head strikes the heating roller 2 head-on. Figure 2 A scraper 41 is arranged next to the upper row of heating rollers 2, with the blade head facing to the right and tilted upward. A scraper 41 is arranged next to the lower row of heating rollers 2, with the blade head facing to the right and tilted downward. The scraper 41 contacts the surface of the heating roller 2 and scrapes off the fiber residue of the filter paper 8 adhering to the surface of the heating roller 2 to prevent the residue from affecting the subsequent conveying of the filter paper 8. A rotating shaft 74 is fixedly connected in the mounting groove 71. A pawl 72 is rotatably set on the outside of the rotating shaft 74. A torsion spring 73 is sleeved on the outside of the rotating shaft 74, with one end of the torsion spring 73 inserted into the inner wall of the mounting groove 71 and the other end of the torsion spring 73 inserted into the pawl 72.

[0026] Furthermore, the motor 3 is mounted on the mounting base 12.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
