Description

Technical Field

[0001] The present invention relates to the technical field of papermaking drying devices, in particular to a drying device for papermaking equipment. Background Art

[0002] Existing drying devices for drying paper generally include a roller that contacts and conveys the paper, and the roller is connected to a device with heated gas. The paper is dried through heat conduction from the roller. During the drying process, the motor rotates continuously, thereby driving the roller to keep it in a rolling state. The device does not have an intermittent pause mechanism, which cannot guarantee the drying time of the roller on the paper, resulting in poor drying effect. The roller needs to be set up for repeated drying, which affects efficiency and takes up a lot of space.

[0003] To this end, we propose a drying device for papermaking equipment. Summary of the Invention

[0009] Preferably, the connecting assembly includes an L-shaped plate, which is rotatably connected to a fixed rod passing through the gear via a torsion spring. The L-shaped plate is also rotatably connected to a clamping rod for clamping the paper. A first telescopic plate with an internal elastic member is fixedly connected to the support frame, the end of the first telescopic plate is fixedly connected to the L-shaped plate, and a limit plate that slides with the paper is fixedly connected to the fixed rod. Preferably, the connecting assembly also includes a fixed plate rotatably connected to the support frame, a second telescopic plate with an internal compression member is fixedly connected to the fixed plate, the end of the second telescopic plate is fixedly connected to a pressure tooth plate that meshes with the gear, and the fixed plate is fixedly connected to the pressure plate via a connecting rod.

[0010] Preferably, the movable component includes a limiting arc plate connected and fixed to the movable groove, the limiting arc plate is pressed and fitted with the bottom of the fan-shaped tooth plate, the top surface of the limiting arc plate is fixedly connected with a protruding rod, and the side of the arc gear is provided with a second sliding groove that slides with the arc limiting plate, and a limiting rod passing through the arc limiting plate is fixedly connected in the second sliding groove, and a compression spring is wound on the limiting rod, and both ends of the compression spring are respectively hung with the fan-shaped tooth plate and the arc limiting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention drives the gear plate through the continuously rotating motor. The gap of the gear plate drives the gap of the sector-shaped tooth plate to stop. Cooperating with the function of the sliding plate and the pressure rod, the roller performs an alternating rotation-stop motion.

On the other hand, the stopping of the rotating roller increases the drying time of the paper, thereby ensuring the drying effect.

[0014] 2. When the plurality of sector-shaped tooth plates of the present invention pass the uppermost position and stop, the continuously rotating cam causes the upper and lower moving limit plates to drive the paper on the non-rotating roller to move up and down, so that the paper moves away from the roller for a short time and then contacts the roller again, thereby preventing the paper from sticking to the fixed roller due to moisture on the paper.

[0015] 3. Through the limit plate and the torsion spring, the adsorption rod can absorb the residual moisture and water marks on the roller to prevent the water marks from being printed on the paper. On the other hand, it can press and limit the rolling to prevent the roller from resetting and rotating when the pressure rod and the sliding plate do not interact with each other.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-Figure 3 The drying device of a papermaking equipment shown in the figure includes a support frame 1, in which a roller 2 that is in contact with the paper is rotatably connected, and input pipes 3 that are connected to the heating device are rotatably connected on both sides of the roller; it also includes a gear plate 4 located at the end of the roller 2; a gap component 5, the gap component 5 is used to continuously rotate the gear plate 4 so as to drive the roller 2 to rotate through the gap; a matching component 13, the matching component 13 is used to connect the gear plate 4 and the roller 2; and a movable component 28, the movable component 28 is used to cooperate with the roller 2 with the gap stopped to make the paper move up and down.

[0030] See also Figure 3-5 The gap assembly 5 shown in the figure includes a motor 6 and a gear 7 fixedly connected to the support frame 1. The output shaft of the motor 6 is fixedly connected to a rotating rod 8 fixedly connected to the central axis of the gear plate 4. The rotating rod 8 rotates with the central axis of the roller 2. A plurality of movable grooves 9 are arranged in a circular matrix on the gear plate 4. The movable groove 9 is movably fitted with a fan-shaped tooth plate 10. The gear 7 is meshed with the gear plate 4 and the gear 7. The support frame 1 is also provided with a connecting assembly 19 that cooperates with the movement of the gear 7.

[0031] See also Figure 5 and Figure 9-10 The gap assembly 5 shown in the figure also includes an arc-shaped limit plate 11 connected to the sector tooth plate 10, the arc-shaped limit plate 11 penetrates into the gear plate 4, and a tension spring 12 hung on the gear plate 4 is fixedly connected to the arc-shaped limit plate 11.

[0032] See also Figure 6-Figure 9 The mating component 13 shown in the figure includes a pressure rod 14 and a pressure plate 15 connected and fixed to the roller 2, a first sliding groove 16 is opened on one of the sector-shaped tooth plates 10, a sliding plate 17 is slidably fitted in the first sliding groove 16 and pressed against the pressure rod 14, an elastic pull rope 18 is hung between the sliding plate 17 and the sector-shaped tooth plate 10, and the pressure plate 15 is pressed against the sliding plate 17.

[0033] See also Figure 2-Figure 4The connecting assembly 19 shown in the figure includes an L-shaped plate 20, which is rotatably connected to a fixed rod 21 passing through the gear 7 through a torsion spring. The L-shaped plate 20 is also rotatably connected to a clamping rod 22 for clamping the paper. A first telescopic plate 23 with an elastic member inside is fixedly connected to the support frame 1. The end of the first telescopic plate 23 is fixedly connected to the L-shaped plate 20. A limiting plate 24 that slides with the paper is fixedly connected to the fixed rod 21. The limiting plate 24 is provided with an adsorption rod 34 that movably cooperates with the roller 2.

[0034] In this embodiment, before the drying process, the end of the paper is first pulled so that the paper extends from the through slot provided on the limiting plate 24, adheres to the roller 2, and passes between the two clamping rods 22. Then, the end of the paper is connected to the external conveying device (the setting of the conveying device is conventional technology), and then the motor 6 is started;

[0035] The motor 6 drives the rotating rod 8 to rotate, thereby driving the gear plate 4 to rotate continuously. The gear plate 4 does not stop during the rotation process. Under the action of the tension spring 12 and the limit arc plate, the fan-shaped tooth plate 10 located in the movable groove 9 is tightly fitted with the gear plate 4. While the gear plate 4 rotates, it drives the gear 7 to rotate in the original position (under the action of the fixed rod 21). Under the action of the matching component 13, the gear plate 4 drives the roller 2 to rotate, thereby moving the paper. The rotating roller 2 continuously inputs heat into the inside of the roller 2 under the action of the input pipe 3 (the other one is the output pipe in the figure);

[0036] The gear plate 4 rotates continuously. When the position of the movable groove 9 on the gear plate 4 corresponds to the position of the gear 7, the gear 7 disengages from the meshing of the gear plate 4 and meshes with the sector gear 7. Under the action of the connecting component 19, the gear 7 remains stationary, so that the sector gear plate 10 remains stationary, and the gear plate 4 continues to rotate. The gear plate 4 rotates away from the sector gear plate 10, the arc-shaped limit plate 11 moves relative to the gear plate 4, and the tension spring 12 stretches. At the same time, under the action of the matching component 13, the drum 2 does not rotate, thereby realizing the continuous rotation of the motor 6 and the gear plate 4, and the drum 2 performs an alternating rotation-stop motion. This method ensures that the drum 2 dries the paper for a long time and ensures the drying effect.

[0037] The principle of the mating assembly 13 is as follows: when the gear plate 4 drives the sector tooth plate 10 to rotate together (the gear 7 does not contact the sector tooth plate 10), the sliding plate 17 presses the pressing rod 14, driving the pressing rod 14 and the roller 2 to rotate about the rotating rod 8. The continuously rotating gear plate 4 drives the roller 2 to rotate, thereby conveying the paper;

[0038] Just before the sector toothed plate 10 (with the sliding plate 17) contacts the gear 7, the sector toothed plate 10 is at the top, and the sliding plate 17 moves along the first sliding groove 16 through the action of the fixed pressure plate 15. The elastic pull rope 18 is pulled, and the sliding plate 17 is separated from the pressure rod 14. At this time, the drum 2 remains stationary. It is worth noting that the adsorption rod 34, on the one hand, absorbs the residual moisture on the drum 2, and on the other hand, presses to limit rolling, so as to prevent the drum 2 from resetting and rotating when the pressure rod 14 and the sliding plate 17 do not interact with each other.

[0039] After the sliding plate 17 rotates one circle, the sliding plate 17 contacts the pressing rod 14 again, thereby driving the roller 2 to rotate again, and the reciprocating motion cooperates with the action of the movable assembly 28 to prevent the paper from sticking to the fixed roller 2.

[0040] Example 2

[0041] See also Figure 5-Figure 6 The connecting assembly 19 shown in the figure also includes a fixed plate 25 rotatably connected to the support frame 1, and a second telescopic plate 26 with a compression member inside is fixedly connected to the fixed plate 25. The end of the second telescopic plate 26 is fixedly connected to a pressure tooth plate 27 engaged with the gear 7. The fixed plate 25 is fixedly connected to the pressure plate 15 through a connecting rod.

[0042] In this embodiment, when the gear plate 4 is in meshing contact with the gear 7, the gear 7 is driven to overcome the compression member in the second telescopic plate 26 and the action of the pressing gear plate 27, so that the gear 7 rotates in its original position;

[0043] When the sector tooth plate 10 contacts the gear 7 and does not rotate with the gear plate 4, the sector tooth plate 10 is located at the uppermost position through the first telescopic plate 23. At this time, the movable component 28 is cooperated to make the multiple sector tooth plates 10 move upward quickly for a certain distance and then drop, so that the gear 7, the fixed rod 21 and the fixed plate 25 move back and forth upward along the direction of the second telescopic plate 26. The limit plate 24 moves up and down and at the same time, it rotates adaptively under the action of the torsion spring, so that the adsorption rod 34 is always pressed against the roller 2. The limit plate 24 that moves up and down drives the paper on the non-rotating roller 2 to move up and down, so that the paper is away from the roller 2 for a short time and then contacts the roller 2 again, avoiding the paper sticking to the fixed roller 2 due to moisture on the paper.

[0044] Example 3

[0045] See also Figures 8-10The movable component 28 shown in the figure includes a limiting arc plate 29 connected and fixed to the movable groove 9, the limiting arc plate 29 is pressed and fitted with the bottom of the sector tooth plate 10, and a protruding rod 30 is fixedly connected to the top surface of the limiting arc plate 29. A second sliding groove 31 is provided on the side of the arc gear 7 to slide with the arc limiting plate 11. A limiting rod 32 passing through the arc limiting plate 11 is fixedly connected in the second sliding groove 31, and a compression spring 33 is wound on the limiting rod 32. The two ends of the compression spring 33 are respectively hung on the sector tooth plate 10 and the arc limiting plate 11. In this embodiment, when the sector tooth plate 10 (the sector tooth plate 10 that rotates with the gear plate 4 and is located at the highest point) contacts the gear 7, the gear plate 4 continues to rotate, driving the limiting arc plate 29 and the protruding rod 30 to rotate, and the protruding rod 30 presses the sector tooth plate 10, thereby causing the sector tooth plate 10 to move up and down, and at the same time, the arc limiting plate 11 slides and cooperates with the limiting rod 32, and the compression spring 33 cooperates.
