Description

Technical Field

[0001] The invention relates to the field of building materials or the field of building materials production and manufacturing, and in particular to a device and a production process for quickly sticking a cork pad on the back of a stone plastic floor. Background Art

[0002] Stone plastic floor is a new type of environmentally friendly floor developed based on high technology. Its main components are 70% to 80% stone powder and 20% to 30% polyvinyl chloride. SPC floor is a product made by extruding PVC base material through an extruder combined with a T-die, and then pressing and laminating the PVC wear-resistant layer, PVC color film and PVC base film at one time through a four-roll calender unit.

[0003] Stone plastic floor is an environmentally friendly floor that is 100% free of formaldehyde and heavy metals. It is non-toxic and odorless, not afraid of water, fire, or moisture, and has excellent stability and durability. Ordinary solid wood composite floor or laminate floor has certain formaldehyde problems, is not resistant to blisters, and will make noises after the size changes. Compared with solid wood composite floor, the advantages of stone plastic floor are low price, waterproof and fireproof, not easy to deform, and wear-resistant. However, stone plastic floor has high density, heavy weight, hard feeling underfoot, and thin overall thickness. For consumers in the interior home improvement market who are accustomed to wooden floors and tiles, the market has appeared a process of bonding stone plastic floor and cork layer together.

[0004] The traditional SPC floor back-pasted cork pad (ACE) uses cold glue to apply on the surface of the cork pad and use special equipment to stick it on the back of the SPC floor. The production efficiency is low, the linear speed of the conveyor belt is less than 12m / min, and the utilization efficiency is only 15%-20%. After long-term research, the inventor found that the main reason is that the anti-fracture force of the cork pad is only 10-11N. If the linear speed exceeds 12m / min, the cork pad will deviate or even be broken.

[0005] In order to increase the speed of cork pad pasting and expand production capacity, some international and domestic companies use a large-format SPC substrate board to cover the entire board with ACE cork pad, and then cut it into small boards before entering the slotting process. Although this film pasting method is efficient, the subsequent sawing and slotting are very difficult, and the defective rate is high. The reason for the high defective rate is that the SPC stone plastic floor pasted with cork pad will scratch the surface of the floor and ACE under the action of the transport roller and the pressure roller of the multi-blade saw when it enters the multi-blade saw to be cut into small boards. When slotting, due to the cork pad attached to the backboard, the pressure wheel belt of the slotting machine is not pressed tightly, and the slotting accuracy will be affected, resulting in a large number of defective products. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a device and a production process for quickly pasting a cork pad on the back of a SPC floor. By using an adhesive tape as traction, the film pasting line can paste and cut the film at a high speed; at the same time, the cork pad can maintain good passability under the auxiliary traction of the transparent tape; because the transparent tape is sticky, the cork pad and the tape are firmly adhered before entering the pressure roller at the same time, and will not cause deviation, thereby meeting the requirements of SPC stone plastic floor pasting.

[0007] The present invention achieves the above technical objectives through the following technical means.

[0008] A device for quickly attaching a cork mat to the back of a stone plastic floor, comprising a conveying device, a pressing roller device, an unwinding machine and an adhesive tape;

[0009] A cork pad is installed on the unwinder, and the tape is rotatably installed on the tape fixing frame. One end of the cork pad passes through the roller assembly, and the tape is bonded to the cork pad through the roller assembly and then enters the pressing roller device together; the pressing roller device is located on the conveying device and is used to press the cork pad and the tape tightly to the stone plastic floor; the conveying device is used to convey the stone plastic floor.

[0010] Furthermore, the roller assembly includes a plurality of rollers and a fixed bracket. A plurality of rollers are provided on the path between the cork pad and the pressure roller device for conveying one end of the cork pad to the pressure roller device. The adhesive tape is bonded to the cork pad through any one of the rollers.

[0011] Furthermore, the adhesive tape has a breaking resistance of not less than 30N, which can protect the cork pad from being broken at a high line speed.

[0012] Furthermore, it also includes a cutting device, which is installed on the conveying device and located at the rear end of the pressing roller device.

[0013] A production process for quickly attaching a cork pad to the back of a stone plastic floor comprises the following steps:

[0014] Install the cork mat in a roll with a fixed width on the unwinder, and install the tape on the tape fixing rack;

[0015] By using the device for quickly sticking the cork pad on the back of the stone plastic floor, the adhesive tape is made to pass through the roller assembly and adhere to the cork pad, and then enter the pressing roller device together;

[0016] The conveying device conveys the stone plastic floor to the pressing roller device, and the stone plastic floor is pressed and fitted tightly with the cork pad and the adhesive tape by the pressing roller device.

[0017] Further, the method further comprises the following steps:

[0018] The compacted and bonded stone plastic floor and cork mat are transported to the cutting device for cutting.

[0019] Furthermore, the transmission line speed of the conveying device is not less than 21 m / min.

[0020] The beneficial effects of the present invention are:

[0021] 1. The device for quickly sticking a cork pad on the back of a stone plastic floor of the present invention adheres the tape to the cork pad through a roller assembly, and uses the tape as a traction, so that the film sticking line can stick and cut the film at a high speed; at the same time, the cork pad can maintain good passability under the auxiliary traction of the transparent tape.

[0022] 2. The device for quickly sticking a cork pad on the back of the stone plastic floor of the present invention utilizes the stickiness of the transparent tape, so that the cork pad and the tape are firmly stuck before entering the pressing roller at the same time and will not cause deviation. In this way, the pressing roller device can ensure that the cork pad and the stone plastic floor will not deviate or be misaligned during the pressing process.

[0023] 3. The production process of quickly pasting cork pads on the back of the stone plastic floor described in the present invention uses an adhesive tape as a traction, which can improve the line speed of the conveyor belt while improving the quality of the film and reducing the unqualified rate.
