Description

Film covering device of floor lock catch system

Technical Field

The invention relates to the technical field of film laminating equipment of a locking system of a wooden floor, in particular to a film laminating device of a locking system of the floor.

Background

The mounting system of wooden floors includes various kinds, and the locking system is one of them that the connection stability is relatively good and the mounting is more efficient. The processing and manufacturing of the locking system can form a larger open surface at the side edge of the wooden floor, namely a tenon structure surface and a groove structure surface of the locking system, and after the locking system is installed, the noise problem is caused by the running-in between the two surfaces. Although the prior art has the technical scheme of sealing the tenon structure surface and/or the groove structure surface by coating the molten paraffin, the effect is not good, and particularly on the tenon structure surface and/or the groove structure surface of the solid wood floor, the paraffin layer is easy to air-dry, abrade or fall off.

In the U.S. patent database, publication No. US2013/0008118a1 entitled "silent floor System and method for silencing the same" (Non-Squeaking Wood floor System and Methods), discloses a technical solution for preventing the floor board locking System from making a noise by attaching a protective film (e.g., OPP film) to the locking System, and also discloses a device for applying a film. The device presses and covers the protective film on the locking system by a plurality of press rollers which are arranged in different inclinations according to different inclinations of each surface of the locking system.

Chinese patent database, publication No. CN109624290A entitled "method for laminating film on wood floor, laminating apparatus and wood floor", discloses a technical solution for simultaneously attaching protective films (e.g. polyethylene film) to both sides of the floor, and also discloses a device for implementing the laminating. The device is characterized in that two groups of pressing wheels which are respectively arranged opposite to two side surfaces of the solid wood floor are used for pressing and covering the protective film on the locking system, and the requirements of floor covering films with different widths are met by the first slide rail and the second slide rail with adjustable intervals.

Disclosure of Invention

However, through the creative research and discovery of the inventor, the film covering device of the locking system of the first mode has the following defects:

the device coats the film on two sides (a tenon structure and a groove structure) of the floor block simultaneously, the surfaces of the tenon structure and the groove structure can be pressed on the protective film through the continuously arranged pressing wheels with different inclination angles, but in the concave position of the tenon structure and the groove structure, the protection film can be further inclined through the pressing wheels, but the protection film is preferably manually finished so as to adapt to the complex shape of the concave position of the tenon structure and the groove structure, and the protective film is ensured to be attached. Therefore, such a technique has a problem that the protective film is not sufficiently attached (which easily causes the protective film to fall off during transportation and storage), or has a problem that the production efficiency is low due to manual sticking.

Through creative research and discovery of the inventor, the film covering device of the locking system of the second mode has the following defects:

the width of the locking system of the floor block also changes along with the width change of the floor and shows slight difference in shape, but mainly due to the change of the width of the locking system, the distance adjustment of the first pressing wheel and the second pressing wheel can only adapt to the change of the width of different floor blocks, but can not adapt to the difference of the width and the shape of different locking systems. For example, after the width of the locking system is changed, the x-axis central line of the protection film unreeled by the unreeling mechanism and the x-axis central line of the tenon structure are not overlapped any more. The position of each first pressing wheel is manually adjusted by taking the x-axis central line of the unwinding mechanism as a reference, so that the x-axis central line of the tenon structure and the x-axis central line of the protective film can be coincided again according to the floor block placed at the limiting position formed by each first pressing wheel. Meanwhile, although the second pressing wheels only play a role in balancing the pressure of the first pressing wheels, the second pressing wheels are in one-to-one correspondence with the groove structures of the floor blocks (in the technical scheme, the purpose of design is to cover the groove structures at the same time), so that the second pressing wheels which change the position of the y axis direction cannot be limited and abutted again by the groove structures which change the width and the shape only by moving the second pressing wheels integrally. The position of each second pressure wheel needs to be manually adjusted, so that the second pressure wheels can be abutted against all the positions of the groove structures again and play a limiting role. However, the above-described operation is very complicated.

Meanwhile, in the technical scheme, although the first pressing wheel and the second pressing wheel are correspondingly arranged on the first side surface and the second side surface of the floor, no specific technical scheme is given.

The film covering is used for providing flexible isolation between a tenon structural surface and a groove structural surface of the locking system and avoiding noise generated by friction of the tenon structural surface and the groove structural surface. Through creative research and discovery of the inventor, the contact between the isolation tenon structure surface and the groove structure surface can be realized only by coating the film on the tenon structure, and the silencing effect is achieved. It makes no sense to coat the tongue structure with the groove structure at the same time and, possibly, in some cases, is detrimental. For example, the double-layer film can form excessive tight fit between the tenon structure and the groove structure, the difficulty of assembly and disassembly is increased, and noise can be generated due to the excessive tight fit.

That is, the distance between the seventh pressing portion and the reclining mechanism 6 is longer than the distance between the fourth pressing portion and the reclining mechanism 6. As viewed along the z-axis, the bottom of fifth puck 55 is at the same height as the bottom of third puck 53, and the bottom of sixth puck 56 is at a higher height than the bottom of eighth puck 58. That is, the fifth pressure applying portion is equal in height to the third pressure applying portion, and the sixth pressure applying portion is higher than the eighth pressure applying portion.

Preferably, the eighth pressing wheel 58 is a conical wheel, so the projection of the eighth pressing portion formed on the y-z plane is a convex arc, and the wheel body is made of an elastic material, so the pressing surface of the eighth pressing portion is an elastic surface.

The fifth to eighth pressing portions are provided to complete the conformable coating of the protective film 7.

Preferably, referring to fig. 14, a plurality of limiting pressing wheels 59 matched with the backer mechanism 6 are arranged behind the pressing mechanism 5, and the outer edges of the limiting pressing wheels 59 at least partially abut against the tongue side end surface 115.
