Description

Technical Field

[0001] The invention relates to the technical field of transportation equipment, and in particular to a raw material conveying device for cardboard production. Background Art

[0002] Corrugated paperboard, also known as corrugated paperboard, is made of at least one layer of corrugated core paper and one layer of paperboard. This multi-layer structure makes the corrugated paperboard have good elasticity and extensibility.

[0003] Corrugated paper, also known as corrugated core paper, is the raw material paper used to form the corrugated core of corrugated board. It requires good fiber bonding strength, flat paper surface, good tightness and stiffness, and a certain degree of elasticity. In the production and processing of corrugated board, corrugated paper is usually rolled into a cylindrical paper roll structure with a diameter of up to 1-2m, so the paper roll itself is heavy. In the board production workshop, the paper roll is usually transported by forklifts and other transportation equipment.

[0004] A Chinese patent with authorization announcement number CN206901712U discloses a vertical paper roll handling forklift, which includes a vehicle body and a slide plate that slides up and down along a slide rail, the slide rail being fixed to the front end of the vehicle body; a pair of semicircular paper roll clamps are hinged on the slide plate, the paper roll clamps are driven by a hydraulic cylinder to rotate around a hinge axis, and the axis of the paper roll clamps is vertically arranged; a paper roll support plate is integrally arranged at the bottom end of the paper roll clamp, and the outer end surface of the paper roll support plate is an inclined surface.

[0005] The above patent provides a pair of semicircular paper roll clamps, and a paper roll support plate is integrally provided at the bottom of the paper roll clamps. The axis of the paper roll clamps is vertically arranged, which enables the forklift to easily clamp the vertically placed paper rolls. The paper roll clamps and the paper roll support plate cooperate to ensure that the paper roll is stable and safe.

[0006] However, due to the small space in some cardboard production workshops, it is difficult for large transportation equipment such as forklifts to move freely in the workshop, and paper rolls cannot be transferred by forklifts. At this time, the paper rolls are generally moved by pushing them to roll. However, the rolling of the paper rolls will cause stains on the outer layer of the paper roll, and will also cause damage to the outer layer of the paper roll. The damaged outer layer of the paper roll needs to be torn off before processing, which wastes raw materials. Summary of the invention

[0007] The present invention provides a raw material conveying device for paperboard production, aiming to solve the problem in the related art that when a paper roll cannot be transported by a forklift due to a narrow space, the paper roll will be damaged by pushing the paper roll to roll.

[0008] The raw material conveying device for cardboard production of the present invention comprises: a base, a running mechanism and a rotating disk;

[0009] A tray is provided on the base;

[0010] The running mechanism comprises a mounting seat and a running wheel, wherein the mounting seat is arranged on the base, and the running wheel is provided with a rotating shaft, and the rotating shaft is rotatably fitted in the mounting seat;

[0011] The tray is rotatably matched with the base, the rotating disk is located between the tray and the base, the rotating disk is rotatably matched with the base, a driving block is provided at the bottom of the tray, a driving groove is provided on the rotating disk, the driving block is slidably matched in the driving groove and can stop against the side wall of the driving groove, a rotating tooth groove is provided on the outer side of the rotating disk, a driving gear is fixedly connected to the mounting seat, and the driving gear is meshed with the rotating disk through the corresponding rotating tooth groove.

[0012] Beneficial effect: When the paper roll is carried by the pallet and the external force pushes the paper roll to move, the raw material conveying device for cardboard production will move synchronously with the paper roll. When the paper roll needs to turn, it only needs to apply corresponding thrust to both sides of the paper roll, and the paper roll can drive the pallet to rotate synchronously. The pallet drives the rotating disk to rotate through the driving block, and the rotation of the rotating disk drives the mounting seat to rotate through the driving gear, thereby realizing the rotation of the running wheel, so that the running wheel is always consistent with the forward direction of the paper roll.

[0013] Preferably, a first elastic member is provided at the bottom of the tray, the top of the first elastic member is fixedly connected to the tray, the bottom of the first elastic member is stopped at the base, a limit block is provided at the bottom of the tray, an avoidance groove is provided on the base, the limit block can extend into the avoidance groove, a limit hole is provided at the top of the avoidance groove, and the limit block can be engaged with the limit hole.

[0014] The effect is that the tray is elastically connected to the base, and the tray can bounce upward when it is empty. At this time, the limit block fits in the limit hole to prevent the tray from rotating so that the paper roll can be loaded on the tray. When the tray is loaded with paper rolls, the gravity of the paper rolls pushes the tray to move downward, so that the limit block extends into the avoidance groove, and the tray can rotate freely.

[0015] Preferably, a second elastic member is provided between the rotating disk and the base, the rotating disk can move up and down relative to the base, and the mounting seat and the base are frictionally matched.

[0016] The effect is that when unloaded, the rotating disk is disengaged from the driving gear under the action of the second elastic member, and the mounting seat remains stationary under the action of friction, thereby locking the mounting seat and preventing the mounting seat from rotating.

[0017] Preferably, both sides of the tray are provided with limit plates, and the limit plates can stop against the paper roll.

[0018] The effect is that when the paper roll is placed on the pallet, the limit plate can stop against both sides of the paper roll, thereby preventing the paper roll from leaving the pallet.

[0019] Preferably, inclined plates are provided on both sides of the base, and the paper roll can roll along the inclined plates onto the tray.

[0020] The effect is that the paper roll can be tilted and rolled upward along the inclined plate onto the tray, making it easier to load and unload the paper roll.

[0021] Preferably, a self-locking component is also provided, which includes a self-locking disk, a matching ring and a self-locking ring. The self-locking disk and the tray are rotationally matched through a third elastic member. The matching ring is arranged on the circumferential side of the self-locking disk. The self-locking ring is arranged on the mounting seat. A push block is provided on the self-locking ring. The push block is rotationally matched with the matching ring. The self-locking ring can push the rotating shaft to move along its axial direction. A slot is provided in the mounting seat, and the rotating shaft can extend into the slot and be clamped therewith.

[0022] Preferably, the limit plate is rotationally matched with the tray, a stop block is slidably matched on the tray, the bottom end of the stop block abuts against the self-locking disk, and the limit plate is meshed with the stop block.

[0023] Preferably, the base is further provided with a roller, the roller is rotatably matched with the base, and the base is further provided with a handle.

[0024] By adopting the above technical solution, the beneficial effects of the present invention are:

[0025] The raw material conveying device for cardboard production of the present invention carries paper rolls through a tray. When an external force pushes the paper roll to move, the raw material conveying device for cardboard production will move synchronously with the paper roll. When the paper roll needs to turn, it only needs to apply corresponding thrust to both sides of the paper roll, and the paper roll can drive the tray to rotate synchronously. The tray drives the rotating disk to rotate through the driving block, and the rotation of the rotating disk drives the mounting seat to rotate through the driving gear, thereby realizing the rotation of the running wheel, so that the running wheel is always consistent with the forward direction of the paper roll. The raw material conveying device for cardboard production of the present invention can realize the transportation of paper rolls, and at the same time, the paper rolls do not contact the ground to prevent damage to the paper rolls.

[0042] like Figure 2 , Figure 5 , Figures 7 to 9As shown, the base 1 is also provided with a self-locking assembly, which includes a self-locking disk 111, a matching ring 112 and a self-locking ring 113.

[0043] like Figure 1 , Figure 2 and Figure 5 As shown, limit plates 9 are further provided on both sides of the tray 2, and the limit plates 9 are rotatably matched with the tray 2. A stop block 15 is provided on the side wall of the tray 2, and the stop block 15 is slidably matched with the tray 2. The bottom end of the stop block 15 is stopped against the self-locking disk 111, and a tooth groove is provided on the stop block 15. The limit plate 9 can engage with the stop block 15. When the tray 2 moves up and down, the limit plate 9 moves up and down along the stop block 15 and rotates under the push of the tooth groove.

[0044] According to the raw material conveying device for cardboard production of the present invention, in the initial state, the first elastic member 4 is stretched, so that the tray 2 is located at the highest point, and the limit block 21 is matched in the limit hole 102, so that the tray 2 is engaged with the base 1 to prevent the tray 2 from rotating, and the limit plates 9 on both sides of the tray 2 are tilted downward and abutted against the base 1. The second elastic member 8 is stretched, so that the rotating disk 6 is located at the highest point, and the rotating disk 6 is out of contact with the driving gear 7, and the mounting seat 51 remains stationary under the action of friction to prevent it from rotating. The tray 2 is pulled to the highest point by the self-locking disk 111 through the third elastic member 12, at which time the connecting rod abuts against the top of the matching hole, the self-locking ring 113 is located above the rotating shaft 53, and the rotating shaft 53 extends out of the mounting seat 51 under the action of the fourth elastic member 14, and at the same time, the prismatic structure of the rotating shaft 53 is matched in the rectangular groove 511, thereby preventing the running wheel 52 from rotating, thereby locking the raw material conveying device for cardboard production to prevent it from moving. The raw material conveying device for paperboard production can be lifted by the handle 17, and at this time, the roller 16 is in contact with the ground, and the staff can move the raw material conveying device for paperboard production to the vicinity of the paper roll.

[0045] The paper roll can move upward along the inclined plate 10 under the push of external force, and finally fall on the tray 2. The weight of the paper roll exerts downward pressure on the tray 2, so that the tray 2 overcomes the elastic force of the first elastic member 4 and moves downward. The limit block 21 enters the avoidance groove 101, thereby unlocking the tray 2, and the tray 2 can rotate freely. When the tray 2 moves downward, the limit plate 9 moves along the stop block 15, so that the limit plate 9 rotates upward and stops with the paper roll. The limit plate 9 is used to prevent the paper roll from leaving the tray 2. The downward movement of the tray 2 can also make the driving block 3 gradually extend into the driving groove 61 until the driving block 3 stops with the bottom of the driving groove 61. At this time, the downward movement of the tray 2 will push the rotating disk 6 to overcome the elastic force of the second elastic member 8 and move downward, so that the rotating tooth groove is engaged with the driving gear 7. During the downward movement of the tray 2, the self-locking disk 111 is driven downward by the third elastic member 12, the matching ring 112 and the self-locking disk 111 are synchronously moved downward, the matching ring 112 pushes the self-locking ring 113 downward through the push block 114, the self-locking ring 113 moves downward and pushes the rotating shaft 53 into the mounting seat 51, so that the rotating shaft 53 is out of contact with the rectangular groove 511, the limit between the rotating shaft 53 and the mounting seat 51 is released, and the running wheel 52 can rotate. At this time, it is only necessary to apply a horizontal thrust to the center of the paper roll, and the raw material conveying device for paperboard production can move with the paper roll. When the paper roll needs to be turned, it is only necessary to apply a corresponding thrust to both sides of the paper roll, and the paper roll can drive the tray 2 to rotate synchronously, the tray 2 drives the rotating disk 6 to rotate through the driving block 3, and the rotation of the rotating disk 6 will drive the mounting seat 51 to rotate through the driving gear 7, thereby realizing the rotation of the running wheel 52, so that the running wheel 52 is always consistent with the forward direction of the paper roll.
