Description

Technical Field

[0001] The present invention relates to the technical field of decorative coil production, and particularly to a decorative coil production device. Background Art

[0002] In the production of decorative materials such as CPL decorative materials and melamine impregnated film decorative materials, it is necessary to thermally press the decorative materials onto a substrate to form a coil, so as to facilitate subsequent transfer to the covering production process.

[0003] Currently, the production method of the coil is to thermally press each decorative material onto the already unwound substrate one by one. After one thermal pressing, a section of the material is wound up, so that the substrate without the combined decorative material enters the thermal pressing working area, and then the decorative material is moved onto the substrate through the device. In this process, the distance between two adjacent decorative materials is controlled according to manual judgment, sometimes wide and sometimes narrow, and manual judgment control will result in a large distance between two adjacent decorative materials on the substrate, causing waste. If the distance between two adjacent decorative materials on the substrate is accurately controlled within a few millimeters, a large amount of substrate can be saved, but it is currently difficult to achieve.

[0004] It can be seen that the prior art still needs to be improved. Summary of the Invention

Detailed implementation

[0031] The present invention provides a production device for decorative coils. To make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present invention. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is more than two.

[0033] Please refer to Figures 1 - 3, the present invention provides a decorative coil production device, which includes, from front to back: an unwinding mechanism 11, a hot pressing section 12, a traction mechanism 13, an elastic mechanism 14, a coating mechanism 15, a deviation rectifying mechanism 16, and a winding mechanism 17; it further includes a mobile adsorption mechanism 4, the mobile adsorption mechanism 4 moves in the length direction of the hot pressing section 12 for moving the decorative material onto the base material in the hot pressing section 12; a visual sensor 5 is provided on the mobile adsorption mechanism 4.

[0034] Specifically, the mobile adsorption mechanism 4 is used to adsorb the decorative material to be fixed by hot pressing and transfer it onto the base material. During operation, after the first piece of decorative material is fixed, the base material is wound up a certain distance to make the hot-pressed base material leave the hot pressing section 12, and the next section of the base material enters the hot pressing section 12; the mobile adsorption mechanism 4 moves, and the boundary position between the hot-pressed base material and the non-hot-pressed base material is located through the visual sensor 5 (there is a color difference between the hot-pressed base material and the non-hot-pressed base material), and the position where the mobile adsorption mechanism 4 is located at this time is set as the reference point. Then the mobile adsorption machine obtains the decorative material to be hot-pressed from the fixed position and moves to a position at an arbitrary specific distance from the reference point (such as 1 mm or 3 mm can be set). After the hot pressing of a new piece of decorative material is completed, the above process is repeated to re-determine the new reference point. By continuously updating the reference point through the visual sensor 5, the mobile adsorption mechanism 4 can move based on a basis, so as to accurately control the distance between two adjacent pieces of decorative materials on the base material.

[0035] The coating mechanism 15 is used to coat the softening agent. After the decorative material is hot-pressed on the base material, since the decorative material is brittle and not easy to wind up, by coating the softening agent before winding, the decorative material can be softened to facilitate winding.

[0036] Specifically, the decorative coil production device of the present invention further includes a control device, the control device is electrically connected to the unwinding mechanism 11, the hot pressing section 12, the traction mechanism 13, the elastic mechanism 14, the coating mechanism 15, the deviation rectifying mechanism 16, the winding mechanism 17, and the visual sensor 5 respectively, and is used to control the operation of each mechanism through a program, and update the reference point according to the visual sensor 5 and calculate the moving distance of the mobile adsorption mechanism 4.

Specifically, the first adsorption mechanism 43 and the second adsorption mechanism 44 can adopt the same structure. During operation, the substrate is located between the two first guide rails 42. The first adsorption mechanism 43 and the second adsorption mechanism 44 can be controlled to move separately or synchronously according to needs. Before the first adsorption mechanism 43 adsorbs the decorative paper, it first moves, locates a new reference point through the vision sensor 5, and then performs the adsorption operation.

Specifically, an air pipe is respectively connected to each suction cup 432. When the suction cup 432 presses downwards, the decorative material is tightly adsorbed. When it is necessary to release the decorative material, the inside and outside of the suction cup 432 are communicated through the air pipe. When the pressure difference is not enough to support the gravity of the decorative material, the decorative material detaches from the suction cup 432.

[0039] Please refer to Figure 5 , in one embodiment, the mobile lifting frame 431 includes a horizontal support rod 4311 and two mobile lifting components; the two mobile lifting components are respectively arranged on the two first guide rails 42; the mobile lifting component includes a base 4312, a first telescopic cylinder 4313 vertically arranged on the base 4312, and a second guide rail 4314; both ends of the horizontal support rod 4311 are respectively connected to the two first telescopic cylinders 4313 and are respectively movably connected to the two second guide rails 4314; the first telescopic cylinder 4313 is used to move the horizontal support rod 4311 along the extending direction of the second guide rail 4314; the suction cups 432 and the vision sensor 5 are fixed on the horizontal support rod 4311. Specifically, the operation of the first telescopic cylinder 4313 and the movement of the base 4312 are controlled by a control device and driven by the driving mechanism 45. The bottom of the first telescopic cylinder 4313 is fixed on the base 4312, and its top is connected to the horizontal support rod 4311. During the telescopic process of the first telescopic cylinder 4313, the horizontal support rod 4311 moves up and down. The second guide rail 4314 plays a limiting role to ensure that the horizontal support rod 4311 moves in the vertical direction.

Specifically, the pressure roller 26 presses the base material against the traction roller 25 to increase the friction between the traction roller 25 and the base material. Under the action of elastic force, the first elastic roller 24 and the second elastic roller 27 can adaptively adjust their positions during the movement of the base material to keep the base material taut.
