Description

Technical Field

[0001] This invention relates to the technical field of pulp board conveying devices, specifically a conveying device for automatic pulp board feeding. Background Technology

[0002] Pulp board is a type of paperboard made from pulp after dewatering and pressing. It typically weighs over 250 grams per square meter. In the paper industry, pulp boards are mainly produced for easy transportation. Since many paper mills do not have their own pulping production lines, they need to purchase pulp boards from pulp mills and then break them down into pulp themselves. The flexible pulp boards are wound on a rotating drum and transported by rotating the drum for subsequent processing.

[0003] Existing devices for conveying feed plates generally include a rotating drum for winding the feed plate, a mating drum, and a limiting rod located between the rotating drum and the mating drum. The rotating drum rotates, causing the feed plate to extend at an angle. Through the limitation of the limiting rod and the action of the mating drum, the conveying is completed. However, as the rotating drum continues to rotate, the thickness of the feed plate wound on the rotating drum gradually decreases, causing the tilt angle of the conveyed feed plate to change. This causes the angle and force of the limiting rod acting on the feed plate to change, affecting the feed plate and causing it to become loose and cracked.

[0004] Therefore, we propose a conveying device for automatic slurry feeding plates. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device for an automatic slurry feeder, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for an automatic feed plate, comprising a support frame and a rotating drum wound with the feed plate, wherein a mating cylinder and a limiting rod are rotatably connected to the support frame; further comprising inclined toothed plates; an adjusting component for moving the toothed plates to adjust the position of the rotating drum; a power component for moving the rotating drum one revolution while simultaneously moving the toothed plates to adjust the gap; and a connecting component for connecting the adjusting component and the power component.

[0007] Preferably, the adjusting assembly includes a connecting rod fixedly connected to the toothed plate, a sliding groove that slides with the toothed plate is provided on the inner side of the support frame, a limiting cylinder is fixedly connected to the other end of the connecting rod, a rotating rod is rotatably provided inside the limiting cylinder, and a first rotating plate is provided at one end of the rotating rod.

[0008] Preferably, a pressure plate is fixedly connected to the other end of the self-rotating rod, and the pressure plate is threadedly connected to the rotating drum via a threaded component.

[0009] Preferably, the power assembly comprises a motor fixedly connected with the support frame, an output shaft of the motor is fixedly connected with a rotating rod, an end of the rotating rod is fixedly connected with an incomplete gear, a gear meshing with the incomplete gear rotates in the support frame, and the gear is in meshing contact with the toothed plate.

[0010] Preferably, the power assembly further comprises a second rotating plate fixedly connected with the rotating rod, a groove is formed in the second rotating plate, the gear is fixedly connected with a plurality of connecting plates arranged in a circular matrix, and the connecting plates are in arc-shaped structure matched with the second rotating plate at the ends.

[0011] Preferably, the connecting assembly comprises a plurality of first rotating shafts and second rotating shafts distributed in a circle, the first rotating shafts are rotatably connected with the first rotating plate, the second rotating shafts are rotatably connected with the incomplete gear, the ends of the first rotating shafts are fixedly connected with sliding plates, the ends of the second rotating shafts are fixedly connected with limiting plates in sliding cooperation with the sliding plates, and one of the first rotating shafts penetrates through the first rotating plate and is fixedly connected with the rotating rod.

[0012] Preferably, the inclination angles of the limiting plates and the sliding plates are consistent with the inclination angle of the toothed plate, so that the moving direction of the first rotating plate is consistent with the direction of the sliding groove.

[0013] Preferably, a movable groove matched with the clamping teeth of the incomplete gear is formed in the middle of the toothed plate, so that the clamping teeth of the incomplete gear do not contact the toothed plate.

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1. With the rotation of the rotating drum and the incomplete gear by one revolution, the gear gap rotates by a certain angle, and the rotating drum remains stable after rotation. The gear rotating by a certain angle drives the toothed plate to move along the sliding groove by a fixed distance, thereby driving the connecting rod, the limiting cylinder, the first rotating plate and the rotating drum to move along the sliding groove by a fixed distance, so that the position of the rotating drum automatically changes with the decrease of the winding thickness of the feeding plate, the relative inclination angle of the feeding plate and the limiting rod remains unchanged, and the stress condition of the feeding plate remains consistent.

[0016] 2. The rotating drum always rotates after the position is adjusted, so that the feeding plate is always wound and stretched out. With the rotation of the rotating drum by one revolution, the gear gap moves by a fixed distance. This mode always cooperates with each other, and the position adjustment of the rotating drum is always related to the winding thickness of the feeding plate, regardless of the situation of stopping rotation, machine stop and the like at any position in the middle.

[0017] 3. When the incomplete gear rotates (i.e. the clamping teeth of the incomplete gear do not contact the gear), the gear does not rotate and remains in the original position stably through the action of the connecting plate and the second rotating plate, so that the gear gap moves by a fixed distance and remains stable in position.

Please refer to Figures 6-7 The power assembly 13 in the drawing further includes a second rotating plate 18 fixedly connected with the rotating rod 15, the second rotating plate 18 is provided with a groove 19, the gear 17 is fixedly connected with a plurality of connecting plates 20 arranged in a circular matrix, and the end of the connecting plate 20 is in an arc-shaped structure matched with the second rotating plate 18.

[0038] In the embodiment, the rotating drum 2 is attached to the pressing plate 12 through a threaded connection, and the flexible pulp feeding plate is inclined to pass through the limiting rod 4 and the matching wheel, and the end of the pulp feeding plate is connected with the traction device (conventional technology matched with the motor 14);

[0039] The rotating principle of the rotating drum 2: start the motor 14 to drive the rotating rod 15 to rotate, thereby driving the incomplete gear 16 to continuously rotate at the original position, under the action of the connecting assembly 21, the self-rotating rod 10 rotates synchronously with the incomplete gear 16, the self-rotating rod 10 drives the connecting rod 7 and the pressing plate 12 to rotate, thereby making the rotating drum 2 rotate, and the pulp feeding plate is wound and stretched out under the cooperation of the traction device;

[0040] The rotating principle of the rotating drum 2: start the motor 14 to drive the rotating rod 15 to rotate, thereby driving the incomplete gear 16 to continuously rotate at the original position, under the action of the connecting assembly 21, the self-rotating rod 10 rotates synchronously with the incomplete gear 16, the self-rotating rod 10 drives the connecting rod 7 and the pressing plate 12 to rotate, thereby making the rotating drum 2 rotate, and the pulp feeding plate is wound and stretched out under the cooperation of the traction device;

[0042] The principle of keeping the position of the tooth plate 5 stable after moving a distance in the gap is as follows: when the teeth of the incomplete gear 16 contact the gear 17, the connecting plate 20 is in position with the groove 19, and the other connecting plates 20 do not contact the second rotating plate 18, so that there is no interaction between the connecting plate 20 and the second rotating plate 18, and the gear 17 is kept stable in the original position when the incomplete gear 16 rotates a certain angle.
