Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and particularly relates to an unwinding device for producing art cardboard. Background Art

[0002] The production process of art cardboard is a complex and delicate process, which involves multiple links to ensure the quality and aesthetics of the final product. The production process of art cardboard first involves waste paper treatment and pulping, and then the prepared pulp is sent to a paper machine for papermaking. On the paper machine, the pulp will go through multiple processes such as pressing, drying, and coating to form the base paper of the cardboard. In order to increase the texture and beauty of the art cardboard, embossing treatment may be carried out. Through an embossing machine or by hand, various patterns, patterns or textures are pressed on the cardboard. The art cardboard may also need to be coated to enhance its gloss, water resistance or wear resistance. At the same time, it may also be colored by printing or hand painting on the cardboard to achieve a specific artistic effect.

[0003] After the base paper is produced and wound into a cylinder, unwinding will be involved in subsequent processes. The current unwinding devices, such as the wrapping paper unwinding device with the publication number of CN111099070A, will all generate lateral displacement during high-speed unwinding. After the lateral displacement, there will be a phenomenon of paper folding and deviation, which directly affects the quality of the product and increases the defective rate of the product. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an unwinding device for producing art cardboard aiming at the above-mentioned existing technical problems, achieving the effect of ensuring product quality.

[0005] In view of this, the utility model provides an unwinding device for producing art cardboard, including:

[0006] An unwinding rack for placing paper rolls;

[0007] Tension rollers, both ends of which are arranged on two parallel side plates of the frame, and multiple tension rollers are arranged along the paper transmission direction;

[0008] A deviation rectifying mechanism for rectifying the lateral position of the paper during transmission.

[0009] In this technical solution, the deviation rectifying mechanism can prevent the paper from deviating excessively during transmission, ensuring product quality.

[0010] Further, the deviation rectifying mechanism includes:

[0011] A deviation rectifying shaft, one end of which is hinged to one side plate of the frame, and the other end is arranged on a deviation rectifying seat. A sliding groove is formed on the other side plate of the frame, and the deviation rectifying seat is slidably arranged in the sliding groove;

[0012] An induction switch, which is used to sense the position of one end of the paper on the deviation correction shaft;

[0013] A deviation correction power assembly, which is controlled by a controller. The controller is electrically connected to the induction switch. The controller can receive the signal of the induction switch and control the deviation correction power assembly to drive one end of the deviation correction shaft to slide in the chute.

[0014] Further, the induction switch includes at least two probes. The two probes are arranged along the length direction of the deviation correction shaft and are close to the end of the deviation correction shaft. The distance between the two probes is the allowable deviation range of the paper.

[0015] In this technical solution, when both probes can sense the paper or when neither of the two probes can sense the paper, it means that the deviation of the paper exceeds the preset allowable range. At this time, the signal is transmitted to the controller, and the controller controls the deviation correction power assembly to move the deviation correction shaft forward or backward along the chute, so that the paper gradually returns to the normal position, thereby realizing automatic dynamic deviation correction.

[0016] Further, the deviation correction power assembly includes:

[0017] A rotating rod, the middle section of which is rotatably arranged on the side plate;

[0018] A connecting seat, which is slidably arranged in the chute and is fixedly connected to the deviation correction seat;

[0019] A deviation correction cylinder, which is hinged on the side plate. The piston end of the deviation correction cylinder is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is rotatably connected to the connecting seat.

[0020] In this technical solution, the controller controls the piston rod of the deviation correction cylinder to extend or retract, causing the rotating rod to rotate, thereby driving the connecting seat and the deviation correction seat to slide in the chute, so as to move one end of the deviation correction shaft forward or backward.

[0021] Further, the induction switch is a diffuse reflection photoelectric switch.

[0022] Further, a dust - patting assembly is arranged on the outer side of the unwinding rack for patting the dust on the unwound paper.

[0023] In this technical solution, the paper roll may experience a period of storage before unwinding. Inevitably, dust will accumulate on the paper roll. By using the dust - patting assembly to pat the dust on the unwound paper, the paper can enter the next process cleanly and neatly.

[0024] Further, the dust - patting assembly includes:

[0025] Dust - beating base, the dust - beating base is fixedly connected to the side plate. Two parallel convex blocks extend upward from the top of the dust - beating base, and fixing holes are provided on the convex blocks;

[0026] Dust - beating rod, the dust - beating rod is arranged between the two convex blocks. Extension shafts extend outward from both sides of the dust - beating rod. At one end of the extension shaft close to the dust - beating rod, the two extension shafts are respectively inserted into the fixing holes of the convex blocks on both sides and are rotatably connected to the convex blocks,

[0027] Dust - beating power assembly, the dust - beating power assembly is arranged at one end of the dust - beating rod close to the extension shaft. The dust - beating power assembly is used to drive the dust - beating rod to rotate around the axis direction of the extension shaft.

[0028] Further, the dust - beating power assembly includes:

[0029] Dust - beating motor, the dust - beating motor is fixedly arranged on the dust - beating base;

[0030] Turntable, the turntable is connected to the output end of the dust - beating motor, and a first pin shaft is arranged at a position deviating from the center of the turntable end face;

[0031] Fixed shaft, one end of the dust - beating rod close to the extension shaft is in a notch shape, the fixed shaft is fixedly arranged in the notch, and a rotating block is rotatably and slidably arranged on the fixed shaft;

[0032] Connecting rod, one end of the connecting rod is rotatably connected to the first pin shaft, and the other end is rotatably connected to the rotating block.

[0033] In this technical solution, when the dust - beating motor is started, the turntable rotates, driving the connecting rod to move. Then, the rotating block at the other end of the connecting rod slides and rotates, causing the dust - beating rod to swing reciprocally around the axis of the extension shaft, so that the rod body between the end of the dust - beating rod far from the dust - beating base and the extension shaft beats the surface of the paper for dust - beating.

[0034] Further, the dust - beating rod sleeve and an elastic rod detachably connected to the rod sleeve.

[0035] In this technical solution, the elastic rod can be detachably replaced, which can reduce the overall replacement cost of the dust - beating rod.

[0036] Further, the unwinding method of the unwinding device includes the following steps:

[0037] S1: Loading, installing the paper roll onto the unwinding rack;

[0038] S2: Unwinding, unwinding the paper roll. During the unwinding process, the deviation - correcting mechanism continuously corrects the lateral position of the paper, and the dust - beating assembly beats the paper for dust - removal.

[0039] The beneficial effects of the present utility model are:

[0040] 1. The deviation correction mechanism can prevent the paper from being excessively offset during transmission, ensuring product quality.

[0041] 2. Before the paper roll is unwound, it may experience a period of storage, which will inevitably accumulate dust on the paper roll. By using the dust - patting component to pat the dust on the unwound paper, the paper can enter the next process cleanly and neatly.

[0042] 3. The elastic rod is detachable and replaceable, which can reduce the overall replacement cost of the dust - patting rod. Description of the Drawings
