Description

Technical Field

[0001] The utility model relates to the technical field of cutting tables, in particular to an unpowered secondary laminating device for a cutting table. Background Art

[0002] A cutting table is an automated cutting device widely used in the fabric cutting process. It uses a cutting head running on the cutting bed to cut the raw material spread on the cutting table body according to a preset cutting stroke. However, for some fluffy and elastic raw materials, large errors are prone to occur due to the looseness of the raw materials, especially when cutting multiple layers of raw materials. To this end, a common practice in the prior art is to use a negative pressure adsorption cutting table body. After the raw material is spread on the upper surface of the cutting table body, a layer of film is covered on the surface of the raw material. The air between the film and the cutting table body is extracted through the adsorption holes on the upper surface of the cutting table body, and the multiple layers of raw material are compacted using atmospheric pressure before cutting.

[0003] When the cutting machine subsequently cuts the fabric, it also cuts the film above the fabric, creating a cutting gap that penetrates the fabric layer, thus affecting the vacuuming effect of the vacuum device. Therefore, while the cutting machine is cutting the fabric, workers are required to simultaneously lay a layer of covering film behind the cutting machine, covering the cut areas with the covering film to reduce air leakage. The existing technology generally uses manual laminating, where the operator manually covers the raw material with film. This method of laminating is extremely inefficient, and the laminating speed cannot keep up with the cutting speed of the machine, affecting the cutting accuracy. Therefore, a non-powered secondary laminating device for the cutting table was designed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0023] See also Figure 1 The utility model provides a technical solution: a non-powered secondary laminating device for a cutting table, comprising a fixed plate 5 fixed on both ends of the cutting table beam, a rotating shaft 6 is fixed on the inner wall of the fixed plate 5 at both ends, a rotating plate 4 is rotatably connected to the rotating shaft 6, the rotating plate 4 is located on the inner side of the fixed plate 5, and a film roller 3 is connected between the rotating plates 4 on both sides, and the film roller 3 is located at the rear side of the cutter head. The cutter head is driven to move for cutting by the movement of the crossbeam. At the same time, the movement of the crossbeam will also drive the film roller 3 to move, so that the film roller 3 moves to the rear side of the cutter head, and the film on the film roller 3 is covered on the area cut by the cutter head to avoid air leakage and improve the vacuum degree.

[0024] It also includes two symmetrically distributed film roller supports 2 fixed at the tail of the cutting table, and a rear film roller 1 is arranged between the film roller supports 2. One end of the film is rolled on the film roller 3, and the other end of the film is rolled on the rear film roller 1. The film is opened or contracted by the movement of the film roller 3, and the film is covered on the area cut by the knife head to achieve secondary lamination, reduce air leakage of the film in the cut area, improve the vacuum degree, ensure the pressure on the cut fabric, and make the surface pressure of the fabric uniform.

[0025] like Figure 4As shown, the film roller 3 includes a coil spring 33, a roller 32 and a central shaft 31. The roller 32 is sleeved on the central shaft 31. The shaft heads at both ends of the central shaft 31 are square. The two ends of the central shaft 31 are respectively inserted into the rotating plates 4 on both sides. The height of the central shaft 31 is controlled by the rotating plates 4. The coil spring 33 is arranged between the central shaft 31 and the roller 32. One end of the coil spring 33 is connected to the central shaft 31, and the other end of the coil spring 33 is connected to the roller 32. When the film is released, the film will drive the film roller 3 to rotate, causing the roller 32 to rotate, and the coil spring 33 will be opened and tensioned. When the cutting is completed and the film roller 3 is reset, the coil spring 33 is no longer tensioned. The elastic force of the coil spring 33 will cause the roller 32 to reset and rotate, and the film will be rotated around the roller 32.

[0026] like Figure 2 As shown, a spring 7 is connected between the rotating plate 4 and the fixed plate 5. The spring 7 is used to apply tension to the rotating plate 4 so that the rotating plate 4 is always in the lowest position, further making the secondary coating on the film roller 3 close to the film on the upper surface of the fabric, reducing the gap between the secondary film and the film on the surface of the fabric, and reducing air leakage.

[0027] The fixed plate 5 is provided with a plurality of threaded holes 9 distributed up and down. The threaded holes 9 are internally threadedly connected to a limit pin 8. The limit pin 8 is located below the rotating plate 4. The limit pin 8 is used to limit the lower travel of the rotating plate 4 to prevent the film roller 3 from pressing on the fabric.

[0028] A rear film roller positioning hole 21 is provided on the film roller bracket 2. The rear film roller positioning hole 21 includes a vertical strip hole. Four inclined holes distributed up and down are provided on one side of the strip hole. The inclined holes are connected to the strip holes. The inclined holes are all distributed obliquely downward. The inclined holes can position the rear film roller 1, adjust the height of the rear film roller 1, and further adjust the height of the secondary coating, so that the height of the secondary coating can adapt to fabrics of different thicknesses.

[0029] The two ends of the rear film roller 1 are connected with shaft head stops 11, which are located on the outer side of the film roller bracket 2. The shaft head stops 11 limit the two ends of the rear film roller 1 to prevent the rear film roller 1 from sliding left and right.

[0030] like Figure 3 As shown, a bushing 61 and a pad 64 are sleeved on the rotating shaft 6, the bushing 61 is located on the pad 64, and the rotating plate 4 is sleeved on the bushing 61. A baffle 63 is fixed to the other end of the rotating shaft 6 by a screw 62. The diameter of the baffle 63 is larger than the aperture of the rotating plate 4. The baffle 63 limits the movement of the rotating plate 4 in the thickness direction to prevent the rotating plate 4 from moving in the axial direction of the rotating shaft 6.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
