Description

Technical Field

[0001] The utility model relates to the field of diamond film coating equipment for stone plates, in particular to a diamond film seamless automatic coating machine capable of splicing multiple rolls of films. Background Art

[0002] In stone processing factories, most precious natural marble slabs need to have a protective film called "diamond film" on their smooth surface to prevent breakage and scratches.

[0003] Existing equipment for diamond film coating of stone slabs, including the applicant's previous patent ZL 202323230960.0, still has some unsatisfactory features in use:

[0004] 1. The structure and manufacturing process of the existing laminating machine determine that its size and shape accuracy are not high, making it difficult to make the reels and laminating rubber rollers parallel to each other, which can easily cause the laminating to deviate and tilt, resulting in wrinkles, overlaps, leaks, hollow bubbles and other problems on the diamond film covered on the board surface.

[0005] 2. The existing commonly used laminating machines generally have only one diamond film hanging tube and one backing paper hanging tube. If you encounter a wider board, the width of one roll of diamond film is not enough. In this case, it is more difficult to deal with. It is impossible to complete the lamination of the entire board surface at one time. Generally, two or more rolls of splicing and laminating are required. Usually, the existing technical solution is: two or more rolls of film are put on the same axis and close together, and the film is laminated at the same time. Although the entire board surface can be laminated at one time, there are the following fatal defects: First, there is a gap between two adjacent rolls, and there must be a gap on the board surface where the coating is missed; second, the length, diameter, and adhesion between the diamond film and the backing paper of multiple rolls of film are different, which will inevitably lead to different forces required for pulling the film and collecting waste paper. The angular velocity provided by the same reel is the same but the linear velocity is different. In other words, the same axis cannot simultaneously meet the different forces and linear velocities required for film release and paper collection of different rolls, which also causes different degrees of tightness of film release and paper collection of several rolls, and ultimately leads to various quality problems such as lamination deviation, wrinkles, bubbles, etc.

[0006] 3. There is another defect, that is, as the diameter of the paper reel becomes larger and larger, the linear speed becomes larger, and the tension and relaxation force of the paper reel is adjusted by the friction force generated by the elastic round belt driven by the diamond film unwinding component, which is sometimes insufficient or too large;

[0007] 4. In addition, the diamond film hung on the diamond film unwinding assembly may sometimes rotate too fast due to inertia, causing the film that has been separated from the backing paper to become loose, and the film attached to the board is very likely to deflect and wrinkle.

[0008] In summary, it is an inevitable demand to develop a multi-roll film splicing and seamless diamond film automatic laminating machine that can solve the above problems. Utility Model Content

[0009] Therefore, based on the above conception, the utility model proposes a seamless automatic diamond film laminating machine that can splice multiple rolls of film, which solves the technical problem of unqualified film quality when multiple rolls of film are spliced ​​due to the deformation of the frame itself, the centering error of the hanging rod shaft, etc., which leads to the non-parallelism between the hanging rod and the die roller, resulting in film deviation, wrinkles, leaks, etc.

[0010] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a diamond film seamless automatic laminating machine capable of laminating multiple rolls of film, comprising a frame, a plate roller, a film pressing roller, a tensioning rod and an integral integrated winding and unwinding mechanism arranged on the frame, wherein a stone plate is placed above the plate roller during operation, the plate roller is used to support the moving stone plate, the film pressing roller is arranged above the plate roller and is connected to a cylinder, which is driven up and down by the cylinder, the integral integrated winding and unwinding mechanism is arranged above the film pressing roller, the integral integrated winding and unwinding mechanism comprises an integral integrated end plate, a diamond film hanging rod, a waste paper hanging rod, a winding motor, a winding driving wheel, a winding driven wheel, an O-belt, a one-way bearing, a friction plate, the integral integrated The end plates are fixedly arranged at both ends of the frame in the length direction, and the two integral integrated end plates are parallel to each other. The diamond film hanging rod is mounted on the side of the integral integrated end plate close to the stone plate, and the diamond film hanging rod is sleeved with a diamond film material cylinder. The integral integrated end plate is provided with a friction plate, and the friction plate is tightened and fitted to the diamond film hanging rod by a spring to apply friction force to it. The integral integrated end plate is provided with a one-way bearing, and the waste paper hanging rod is arranged on the one-way bearing. The integral integrated end plate is provided with a winding motor, the winding drive wheel is connected to the output shaft of the winding motor, and the winding driven wheel is arranged at one end of the waste paper hanging rod, and the O-belt is sleeved between the winding drive wheel and the winding driven wheel.

[0011] Furthermore, during operation, the film pressing roller is height-adjusted according to the thickness of different stone slabs.

[0012] Furthermore, the diamond film material barrel is fixed on the diamond film hanging rod by a clamp, and the diamond film material is stored in the diamond film material barrel.

[0013] Furthermore, the diamond film material includes diamond film and waste paper, and the waste paper is wound around the waste paper hanging rod during operation.

[0014] Furthermore, a tensioning rod is arranged on the frame, and the adhesive-free surface of the diamond film is placed on the tensioning rod, so that the diamond film is tensioned when the stone plate drives the diamond film to move.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] Through the technical solution proposed by the utility model, the parallelism error of the hanging rod can be eliminated to the greatest extent, and it is not limited by the accuracy error of the frame, ensuring that the diamond film remains parallel and does not deviate during film pasting; two sets of independent winding and unwinding devices are arranged on the integral integrated end plate, on which two rolls of diamond film materials can be placed to paste the film simultaneously, and both single-roll and double-roll film materials can be used, and the independent winding and unwinding device is adopted to solve the problem of unqualified film pasting quality caused by inconsistent tightness of film release and paper collection due to hanging multiple rolls of film on the same reel; the driving motor rotates continuously, and the rotation and stopping of the waste paper hanging rod are controlled by the friction between the O-belt and the winding driven wheel. When the plate is pasted with film, the diamond film will drive the diamond film hanging rod to release during the movement of the plate The waste paper hanging rod is rolled up and the continuously driven O-belt drives the waste paper hanging rod to roll up. When one plate is finished with film and is waiting for the next plate, the diamond film hanging rod stops rotating. At this time, the O-belt will be subject to resistance and slip between the winding driven wheel, which will not break the waste paper and can complete the winding work in time when waste paper is produced by unwinding. The waste paper hanging rod is placed on a one-way bearing so that the waste paper hanging rod can only rotate in the driving direction of the motor to prevent the waste paper hanging rod from reversing and causing the rolled up waste paper to loosen, thereby ensuring that the waste paper always remains taut. The friction plate arranged on the integral integrated end plate can apply friction to the diamond film hanging rod to prevent the diamond film from loosening due to the inertia force generated when the plate stops and starts, thereby ensuring that the diamond film remains taut.
