Description

Technical Field

[0001] The present invention belongs to the production equipment of vehicle interior accessories, and particularly relates to an intelligent vehicle-used roll material special-shaped cutting equipment with an indentation function. Background Art

[0002] At present, vehicle sunshade films or sun visors are all made by cutting roll materials. Among them (see Figures 9 - 10 ), for the cutting of a trapezoidal structure with rounded corners, it is cut by two groups of upper and lower cutting knives 91 and 92. Its disadvantages are as follows: First, the raw material utilization rate is low. Since this cutting method cuts one trapezoid by one, there is generally a certain distance between adjacent trapezoids during cutting, resulting in waste of raw materials. Especially between two trapezoids (such as between B1 and B2, between B2 and B3), due to the lower side of the trapezoid, relatively large triangular waste areas 94 and 95 are formed. This waste area accounts for about one-fifth of the trapezoid, that is to say, the waste of raw materials in the prior art is 20%; Second, the production efficiency is low. The prior art basically adopts manual operation. The accuracy of the operation is poor, the action is slow, and the two groups of cutting tools can only cut one trapezoidal plate (film) material once when moving up and down, so the production efficiency is low; Third, the degree of intelligence is low. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent vehicle-used roll material special-shaped cutting equipment with an indentation function, which has high raw material utilization rate, high production efficiency and high intelligence.

[0004] The purpose of the present invention is solved as follows:

[0005] An intelligent vehicle-used roll material special-shaped cutting equipment with an indentation function includes a roll material feeding mechanism, a roll material conveying mechanism and a roll material cutting mechanism arranged in sequence. The roll material feeding mechanism and the roll material cutting mechanism are both arranged on a frame. The roll material cutting mechanism includes an upper cutting knife and a lower cutting knife that cooperates with the upper cutting knife to cut the roll material. The upper cutting knife includes a first cutting knife and a second cutting knife that are spaced apart and arranged on the upper side of the frame;

[0006] The first cutting knife and the second cutting knife are inclined to form the two hypotenuses of an isosceles trapezoid and both have straight cutting knife segments. The upper ends of the two straight cutting knife segments both extend upward and outward to form a first "Y"-shaped cutting edge, and the lower ends of the two straight cutting knife segments both extend downward and outward to form a second "Y"-shaped cutting edge. One side of the first "Y"-shaped cutting edge is a first circular chamfering cutting edge with an included angle less than 90 degrees, and the other side is a second circular chamfering cutting edge with an included angle greater than 90 degrees. One side of the second "Y"-shaped cutting edge is a third circular chamfering cutting edge with an included angle greater than 90 degrees, and the other side is a fourth circular chamfering cutting edge with an included angle less than 90 degrees. The four circular chamfering cutting edges form the four bottom corners of the trapezoid for cutting the roll material;

[0007] Or, the first cutting knife and the second cutting knife are inclined to form two hypotenuses of an isosceles trapezoid, and both have a straight cutting knife section with double-sided blades. On the inner sides of the upper ends of the two straight cutting knife sections, first circular chamfered blades with an included angle less than 90 degrees extend inward along the inner blade towards the inner side.

[0009] As a further improvement of the present invention, the length of the intermittent movement of the coil is the sum of the lengths of the two horizontal centerlines between the first cutting knife and the second cutting knife and the thicknesses of the first cutting knife and the second cutting knife; or the length of the intermittent movement of the coil is the sum of the lengths of the two horizontal centerlines between the first cutting knife and the second cutting knife; the blades of the first cutting knife and the second cutting knife are both serrated blades.

[0010] As a further improvement of the present invention, an upper slide rail and a lower slide rail along the length direction of the frame are provided on the frame. A cylinder or an oil cylinder or a motor controlled by the controller is slidably disposed on the upper slide rail to drive the first cutting knife and the second cutting knife to move up and down to cooperate with the lower cutting knife to cut the coil, and a cylinder or an oil cylinder or a motor controlled by the controller is used to drive the first cutting knife or / and the second cutting knife to move along the length direction of the frame to adjust the width of the cut coil. A cylinder or an oil cylinder or a motor controlled by the controller is disposed on the lower slide rail to drive the lower cutting knife to move along the length direction of the frame to adjust the width of the cut coil.

[0011] As a further improvement of the present invention, on the frame at the shorter side of the distance between the first cutting knife and the second cutting knife, a third upper cutting knife is centrally arranged, and a third lower cutting knife that cooperates with the third upper cutting knife to cut a notch in the coil material; on one side of either the first cutting knife or the second cutting knife on the opposite side of the third upper cutting knife and the third lower cutting knife, a fourth upper cutting knife is arranged, and a fourth lower cutting knife that cooperates with the fourth upper cutting knife to cut a notch in the coil material.

[0012] As a further improvement of the present invention, an upper slide rail and a lower slide rail along the length direction of the frame are arranged on the frame. On the upper slide rail, a cylinder or an oil cylinder or a motor controlled by a controller is slidably arranged to drive the third upper cutting knife and the fourth upper cutting knife to move up and down to cooperate with the third lower cutting knife and the fourth lower cutting knife to cut a groove in the coil material, and a cylinder or an oil cylinder or a motor controlled by a controller is arranged to drive the third upper cutting knife or / and the fourth upper cutting knife to move along the length direction of the frame to adjust the position of the cutting groove. On the lower slide rail, a cylinder or an oil cylinder or a motor controlled by a controller is arranged to drive the third lower cutting knife or / and the fourth lower cutting knife to move along the length direction of the frame to adjust the position of the cutting groove.

On the frame opposite to the indentation forming strip, a backing plate for pressing the coil material tightly with a metal strip is arranged.

[0017] The prominent advantages and positive effects of the present invention compared with the prior art are:

[0018] 1. High raw material utilization rate: The first cutting knife 4 and the second cutting knife 5 of the present invention adopt double-sided blades. When cutting the first inverted trapezoid A1, the left side of the second regular trapezoid A2 is directly formed. By cutting in this way successively, an alternating arrangement of an inverted trapezoid A1, A3, A5 and a regular trapezoid A2, A4 is formed. Except for the waste formed by cutting the rounded corners, almost all of the raw materials are utilized, resulting in a high raw material utilization rate. Compared with the prior art, the raw material utilization rate is increased by 20%.

[0019] 2. High production efficiency: For each cut of an inverted trapezoid A1, A3, A5 in the present invention, a regular trapezoid A2, A4 is formed incidentally, or for each cut of a regular trapezoid A2, A4, an inverted trapezoid A1, A3, A5 is formed incidentally (see Figures 2 - 3 ), doubling the cutting efficiency; while the cutting tool in the prior art can only cut out one trapezoidal plate (film) material for each up and down movement, resulting in low production efficiency.

[0020] 3. The installation position of the cutting tool of the present invention is adjustable, and trapezoidal products with different widths can be processed.

[0021] 4. High degree of intelligence: The present invention uses a controller to control the movement of the cutting tool and the feeding length of the coil material, with high control accuracy, high cutting qualification rate, and high finished product rate. Description of the Drawings
