Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more specifically to a trimming device of a coating compound machine. Background Art

[0002] After the composite fabric is formed by compounding the fabric and the film, the positions on both sides of the fabric edge where the film is not compounded need to be trimmed.

[0003] When the existing edge cutting is performed by the cutting wheel, the two sides of the cutting position are pressed and limited by the guide wheel, so that the position of the composite fabric is not easily offset during the cutting process.

[0004] In order to cut composite fabrics of different thicknesses, the position of the cutting wheel needs to be adjusted according to the thickness of the fabric. At the same time, the position of the guide wheel also needs to be adjusted to ensure the pressure effect on the composite fabric while avoiding excessive squeezing of the fabric and reducing the probability of fabric deformation causing the cutting position to shift.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0011] The utility model is further configured as follows: the pressure wheel comprises a rubber portion and a support portion, the rubber portion is sleeved on the outside of the support portion, and the support portion and the rubber portion rotate relatively.

[0012] The utility model is further configured as follows: the support portion is provided with a sliding opening for the bracket to pass through, the bracket and the sliding opening are slidably connected, and a spring is arranged between the bracket and the sliding opening.

[0014] In summary, the utility model has the following beneficial effects:

At the same time, the height of the two cutting wheels can be adjusted at the same time using the base, and the two cutting wheels rotate at the same axis and speed, ensuring the accuracy of the cutting edge.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0023] like Figure 1 As shown, the present application provides a trimming device for a coating and laminating machine, comprising two bases 1, which are slidably arranged on the coating and laminating machine by means of a screw, and can change the distance between the base 1 and the composite fabric by rotating the screw, wherein the two bases 1 are fixedly connected with a connecting base, and the two bases 1 correspond to the two side edges of the composite fabric respectively.

[0024] like Figure 2 and Figure 3 As shown, two connecting seats are rotatably provided with a cutting wheel 3, and the cutting wheel 3 is located between the two pressure wheels, wherein the connecting seat includes two brackets 2, the brackets 2 are fixed to the base 1 by bolts, and the two brackets 2 are rotatably connected to the cutting wheel 3 by bearings 12, and the cutting wheel 3 is provided with spur holes, and the brackets 2 are penetrated with perforations, and spur columns 4 are rotatably provided in the perforations and spur holes, and the spur columns 4 are meshed with the spur holes, and one of the brackets 2 is fixedly installed with a motor 5 by bolts, and the output end of the motor 5 is fixedly connected to the spur column 4. When the motor 5 is powered on, the motor 5 will drive the two cutting wheels 3 to rotate together through the spur column 4, and the two cutting wheels 3 rotate coaxially and at the same speed, thereby ensuring the cutting speed on both sides of the composite fabric, and thus ensuring the accuracy of edge cutting.

[0025] like Figure 2 and Figure 3 As shown, two connecting seats are rotatably provided with two pressure wheels, and the two pressure wheels are rotatably provided on two brackets 2 respectively, and the cutting wheel 3 is located between the two pressure wheels. The pressure wheels can press and limit both sides of the cutting position of the composite fabric, so that when the composite fabric is cut by the cutting wheel 3, the position of the composite fabric is not easy to change, thereby ensuring the cutting accuracy.

[0026] like Figure 4As shown, the pressing wheel includes a rubber portion 6 and a supporting portion 7. The rubber portion 6 is sleeved on the outside of the supporting portion 7. The supporting portion 7 and the rubber portion 6 rotate relatively. When the composite fabric is pressed, the softness and anti-skid property of the rubber portion 6 can be used to increase the friction between the composite fabric and the rubber portion 6, thereby ensuring the rotation of the rubber portion 6 and increasing the deformation of the rubber portion 6 to avoid excessive pressing of the composite fabric by the pressing wheel.

[0027] like Figure 4 As shown, the support portion 7 is provided with a sliding opening 8 for the bracket 2 to pass through, the bracket 2 and the sliding opening 8 are slidingly connected, the length direction of the sliding opening 8 is consistent with the sliding direction of the base 1, and the side walls of the bracket 2 and the sliding opening 8 are respectively provided with a make way groove 10 and a make way groove 2 11, wherein a spring 9 is arranged between the bracket 2 and the sliding opening 8, and the two ends of the spring 9 are respectively located in the make way groove 10 and the make way groove 2 11.

[0028] Before trimming, it is necessary to rely on the thickness of the composite fabric, rotate the screw, change the distance between the base 1 and the composite fabric, and change the position of the cutting wheel 3, so that the cutting wheel 3 can cut fabrics of different thicknesses. By utilizing the elasticity of the spring 9, the pressing wheel and the cutting wheel 3 can slide relative to each other, ensuring that the cutting wheel 3 can cut fabrics of different thicknesses while ensuring the pressure of the pressing wheel on the composite fabric and the trimming accuracy.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
