Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting machine. Background Art

[0002] The automatic cutting table is equipped with a negative pressure device at the bottom of the cutting table, and after the cloth is laid, a layer of film is artificially covered on the top of the cloth. The bottom of the cutting table is vacuumed to generate negative pressure. Because the top of the cloth is covered with an airtight film, the cloth can be well adsorbed on the cutting table, and the movement of the cutter will not cause the cloth to slide relative to each other. Another advantage of this operation method is that the force on each part of the cloth is uniform, and the cut cloth is exactly the same.

[0003] When the existing cutting machine film covering mechanism is used, such as the prior art with patent number: CN104942862B, it is usually installed on one side of the machine head, and uses its linkage with the machine head to cover the film material on the material to be cut. Because it is a single-layer film material, if the negative pressure is too large, it is easy to suck the film material to break, and if the negative pressure is too small, it cannot further reduce the thickness of the material to be cut.

DETAILED DESCRIPTION

[0023] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0024] See also Figure 1-7 The utility model provides an embodiment: a cutting machine, comprising a frame 1; a first head 3 and a second head 4 are provided on the frame 1; a first winding roller 6 is provided on a side of the first head 3 facing the second head 4, and a second winding roller 7 is provided on a side of the second head 4 facing the first head 3; one end of the film material is connected to the first winding roller 6, and the other end is connected to the second winding roller 7, when the exhaust port inside the frame 1 draws the air inside the frame 1, the film material between the first winding roller 6 and the second winding roller 7 is adsorbed onto the material to be cut.

[0025] To summarize, when the exhaust port inside the frame draws air inside the frame, the film material located between the first winding roller and the second winding roller can completely cover the material to be cut; to ensure that the material to be cut is adsorbed on the frame, which can reduce the thickness of the material after being attached; and improve the stability of the material on the frame, thereby facilitating the machine head to cut the material.

[0026] Furthermore, since the two winding rollers can automatically reel in and release the film material, when the two machine heads are moving, the film material on the two winding rollers will neither interfere with the movement of the machine heads nor be cut by the machine heads; at the same time, the film material between the two winding rollers can cover the material between the two machine heads, thereby further improving the sealing above the material to ensure that the volume of the material after being attached is further reduced and can be stably and reliably located on the frame.

[0027] Furthermore, since both ends of the first winding roller 6 and the second winding roller 7 are provided with lifting members 9, and the lifting members 9 are used to move the first winding roller 6 and the second winding roller 7, the lifting members 9 can be used to push the two winding rollers closer to or away from the material to be cut, which is convenient for covering the film material on the material to be cut; and also convenient for separating the film material from the material to be cut; wherein the lifting member 9 is preferably a cylinder. Specifically, the lifting member 9 is connected to the machine head through a mounting frame 10 provided.

[0028] In order to further improve the adsorption capacity of the equipment for materials, a first coating roller 5 is further provided on the side of the first head 3 away from the second head 4, and the first coating roller 5 is linked with the first head 3 to cover the film material on the first coating roller 5 on the surface of the material to be cut. Therefore, when the first head 3 moves, the first coating roller 5 can cover the film material on the material to be cut;

[0029] Similarly, a second coating roller 8 is provided on the side of the second head 4 away from the first head 3, and the second coating roller 8 is linked with the second head 4 to cover the film material on the second coating roller 8 on the surface of the material to be cut.

[0030] Based on this, by utilizing the cooperation between the two laminating rollers and the two winding rollers, the sealing performance of the film material to the material to be cut can be improved, so that when the material is adsorbed, its thickness can be further reduced.

[0031] On the basis of the above scheme, since the frame 1 is also provided with a feed guide roller frame 11, and the feed guide roller frame 11 is provided with a film material unwinding guide roller 14 and a material unwinding guide roller 13, the film material and the material can be parallel to the frame 1, so that the film material and the material can enter the frame 1 horizontally. Specifically, the film material unwinding guide roller 14 and the material unwinding guide roller 13 are both installed on the frame 1 through the first bracket 12 provided.

[0032] Furthermore, since the frame 1 is also provided with a discharge guide roller frame 2, wherein the discharge guide roller frame 2 is provided with a first residual material guide roller 20 and a second residual material guide roller 21, and both ends of the first residual material guide roller 20 and the second residual material guide roller 21 are connected to the frame 1 through a support frame 22. Therefore, the two residual material guide rollers can be used to guide the residual material to be stably and reliably wound up by the winding device on one side of the frame. For example, the first residual material guide roller 20 guides the film material after cutting to flow to the waste winding device on one side of the frame; the second residual material guide roller 21 guides the material after cutting to flow to the material collecting device on one side of the frame.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
