Description

Technical Field

[0001] The utility model relates to a cutting device, more particularly to a cutting device for a surface film of an artificial board. Background Art

[0002] In order to improve the smoothness and aesthetics of the surface of the artificial board, a special artificial board surface film is laid on the surface of the artificial board, and then hot pressing is performed by a hot press so that the artificial board surface film is tightly attached to the artificial board. The artificial board surface film is rolled when it is received, so it needs to be cut by a cutting device. The existing cutting device mainly consists of a frame, a cutting mechanism and an unwinding roller. After the unwinding roller unwinds the artificial board surface film to an appropriate length, the cutting blade of the cutting mechanism is lowered to cut the artificial board surface film. However, since the length of the artificial board is generally more than 2 meters, the artificial board surface film required to be cut is also long. Therefore, when the unwinding roller unwinds the artificial board surface film during actual operation, a worker needs to hold the artificial board surface film end and move it to the appropriate position to cut it. Although this can ensure the cutting quality, it is indeed impossible to achieve the automation of cutting, and the working efficiency is not high. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments, but this does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0019] See Figures 1-4 The utility model provides a cutting device for the surface film of an artificial board, comprising a frame 1, a cutting mechanism 2 installed in the frame 1, and a reeling roller 3 installed at one end of the frame 1. A conveying roller pair 5 is installed on the frame 1 on the side of the cutting mechanism 2 close to the reeling roller 3. The conveying roller pair consists of two active rollers that rotate relative to each other, forming a conveying mechanism for the surface film 10 of the artificial board. Two tensioning rollers 4 are installed on the frame 1 between the conveying roller pair 5 and the reeling roller 3. The two tensioning rollers 4 are staggered up and down to form tension on the surface film 10 of the artificial board being conveyed, thereby reducing the risk of deviation during the conveying process. A bracket 6 is installed on the frame 1 on the side of the cutting mechanism 2 away from the reeling roller 3, and a transverse movement mechanism 7 is installed on the bracket 6. The transverse movement mechanism can use an electric slide rail to achieve transverse movement of the film transfer disk 9. The driving end of the transverse movement mechanism 7 is equipped with a lifter 8. The end of the lifter 8 is equipped with a mounting plate. Two film transfer trays 9 are mounted on the mounting plate. The two film transfer trays 9 are respectively used to absorb the two end corners of the artificial board surface film 10, achieving reliable and stable film transfer. The film transfer tray 9 is equipped with two film stripping sub-discs 90, and a film suction sub-disc 91 is located between the two film stripping sub-discs 90. The film suction sub-disc 91 and the film stripping sub-disc 90 operate at staggered times. That is, when the film suction sub-disc 91 is adsorbing the artificial board surface film 10, the film stripping sub-disc 90 is inactive. When the film suction sub-disc 91 releases its adsorption on the artificial board surface film 10, the film stripping sub-disc 90 operates, allowing the film transfer tray 9 to separate from the artificial board surface film 10 more quickly. Through the above design, the cutting device of the utility model can achieve automatic movement of the end of the artificial board surface film 10, thereby solving the problem of manually moving the end of the artificial board surface film 10 in the prior art, realizing the automation of the artificial board surface film 10 cutting and greatly improving work efficiency.

[0020] In this embodiment, the bottom end surfaces of the film stripping sub-disc 90 and the film absorbing sub-disc 91 are flush, which is conducive to better adsorption of the surface film 10 of the artificial board.

[0021] The film-absorbing sub-disc 91 has multiple suction cups 92 mounted therein. The suction cups 92 are connected to the vacuum pump air circuit via an exhaust hose, and the end faces of the suction cups 92 are flush with the end faces of the film-absorbing sub-disc 91. The film 10 on the surface of the artificial board is absorbed by evacuating the interior of the suction cups 92.

[0022] like Figure 3 and Figure 4As shown, the demolding disc 90 has multiple piston holes 94, with air supply hoses mounted at the upper ends of these holes. Below these holes are positioning holes 95 of the same diameter as the piston holes 94. The sidewalls of these positioning holes 95 are provided with multiple venting slots 96, which extend through the demolding disc 90 along the axis of the positioning holes 95. A resilient piston assembly is movably mounted within the piston holes 94, extending into the positioning holes 95. A push-up block 93 is mounted at the distal end of the resilient piston assembly. Initially, the push-up block 93 is located within the positioning holes 95 and flush with the bottom of the demolding disc 90. The portion of the resilient piston assembly located within the piston holes 94 blocks the venting slots 96. When high-pressure gas is introduced into the piston holes 94, the pressure of the gas causes the resilient piston assembly to move downward, causing the push-up block 93 to extend from the positioning holes 95, pushing downward the artificial board surface film 10 in contact with the demolding disc 9, creating a gap between the artificial board surface film 10 and the demolding disc 9. As the air is continued to be added, the elastic piston assembly continues to move downward. When the piston body 97 of the elastic piston assembly completely enters the positioning hole 95, the piston hole 94 is connected to the exhaust groove 96. At this time, the gas in the piston hole 94 can pass through the exhaust groove 96 and enter the gap, forming a blowing of the artificial board surface film 10, further accelerating the separation speed of the artificial board surface film 10 and the transfer disc 9, thereby achieving rapid separation of the two and avoiding the problem of the artificial board surface film 10 self-adhering to the transfer disc 9 and following the transfer disc 9 to move upward.

[0023] The elastic piston assembly includes a piston body 97 and a spring 99. A stopper 100 is fixed to the wall of the piston hole 94 between the two ends of the exhaust groove 96. The piston body 97 is inserted into the piston hole 94 and fixedly connected to the top block 93 via a connecting rod 98. The spring 99 is sleeved on the connecting rod 98, and the two ends of the spring 99 are respectively in contact with the stopper 100 and the piston body 97. In the initial state, the spring 99 is in a freely extended state. When the air supply to the piston hole 94 is stopped, the piston body 97 can be reset under the spring force of the spring 99, forming a seal on the exhaust groove 96, and the top block 93 can also be reset.

[0024] The operating principle of the present utility model is as follows: first, one end of the artificial board surface film 10 is sequentially passed over two tensioning rollers 4 and placed between the pair of conveyor rollers 5. Simultaneously, the end of the artificial board surface film 10 is passed through the cutting mechanism 2 and placed below the transfer plate 9. Next, the transfer plate 9 is lowered by the lifter 8, making contact with the artificial board surface film 10. The vacuum pump is activated to evacuate the suction cup 92, causing the artificial board surface film 10 to adhere to the bottom of the transfer plate 9. To facilitate the transfer plate 9's movement of the artificial board surface film 10, the transfer plate 9 is slightly raised so that the end of the artificial board surface film 10 does not contact the surface of the frame 1. Then, the unwinding roller 3, the pair of conveyor rollers 5, and the transverse mechanism 7 are simultaneously activated, moving them in a synchronized manner, to move the end of the artificial board surface film 10 to a predetermined position. The cutting mechanism 2 is then activated to cut the artificial board surface film 10. Once cutting is complete, the transverse mechanism 7 is activated again to move the artificial board surface film 10 out of the frame 1 to the storage area. When the artificial board surface film 10 is located in the placement area, the vacuuming of the suction cup 92 is stopped, and then air is supplied to the piston hole 94, so that the top block 93 is moved out of the positioning hole 95, and air is blown into the gap between the artificial board surface film 10 and the transfer plate 9, so that the artificial board surface film 10 is quickly separated from the transfer plate 9. Finally, the transfer plate 9 is reset and can be controlled again to suck the end of the artificial board surface film 10 to cut the next piece of artificial board surface film 10.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
