[0025] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] See also Figure 1-8 As shown, a tangent spacing control device for a wire cutting machine comprises a first spacing switching roller 1, a second spacing switching roller 2, a third spacing switching roller 3, two strip plates 4 distributed in an eight-shaped shape, an L-shaped plate 8, a slide seat 9, a first oil cylinder 10, a bearing 11, a guide rail 12 and a second oil cylinder 14. The first spacing switching roller 1, the second spacing switching roller 2 and the third spacing switching roller 3 are alternately arranged from left to right between the two strip plates 4 distributed in an eight-shaped shape, and one end of the two strip plates 4 is connected to each other through a second connecting rod 7. The first spacing switching roller 1, the second spacing switching roller 2 and the third spacing switching roller 3 are all in contact with a tangent 15 portion of a ray distribution area through an adjusting mechanism. The output end of the first oil cylinder 10 located in the adjusting mechanism is connected to a bearing 11 located on the second connecting rod 7. One end of the L-shaped plate 8 is rotatably mounted on the first connecting rod 6, and the first connecting rod 6 is mounted between the other ends of the two strip plates 4.

[0027] The adjustment mechanism also includes a guide rail 12 and a second oil cylinder 14. The two guide rails 12 are respectively connected to the two slide seats 9 located on the surface of the L-shaped plate 8. The output end of the second oil cylinder 14 is connected and fixed to the middle of the other end surface of the L-shaped plate 8, and a connecting piece 13 is installed on the cylinder body of the second oil cylinder 14.

[0028] The first oil cylinder 10 is extended and retracted to push and pull the second connecting rod 7 connected via the bearing 11, and the first connecting rod 6 located between the other ends of the two profile plates 4 is rotatably connected to the corresponding end of the L-shaped plate 8, so that the profile plate 4 and the first spacing switching roller 1, the second spacing switching roller 2 and the third spacing switching roller 3 connected thereto are all in a side rotation state, and at the same time, the second oil cylinder 14 is cooperated to tilt and move the connected L-shaped plates 8 up and down along the guide rail 12, thereby adjusting the horizontal movement position of each spacing switching roller, and providing an adjustable push-pull force for the corresponding intermediate ring groove on each spacing switching roller to contact the tangent 15 part.

[0029] The surfaces of the first spacing switching roller 1, the second spacing switching roller 2 and the third spacing switching roller 3 are respectively and equidistantly provided with the first inter-position annular groove 110, the second inter-position annular groove 210 and the third inter-position annular groove 310, and the distribution states of the first inter-position annular groove 110, the second inter-position annular groove 210 and the third inter-position annular groove 310 respectively correspond in sequence to the line spacings of the tangent 15 parts in the radial distribution area, thereby improving the accuracy of the adjustment position of the tangent 15 spacing and ensuring that each tangent 15 part is accurately located in the corresponding inter-position annular groove.

[0030] like Figure 8As shown, the spacing between the first inter-position annular grooves 110 is b, the spacing between the second inter-position annular grooves 210 is N•b, and the spacing between the third inter-position annular grooves 310 is N+1•b, where N is a number greater than 1. The difference in the inter-position annular grooves allows material slices of different thicknesses to be cut.

[0031] Most of the structure of the profile plate 4 is in the shape of a quarter arc, and short shafts 5 are distributed and fixedly installed on the profile plate 4. The quarter arc-shaped profile plate 4 ensures that the first spacing switching roller 1, the second spacing switching roller 2, and the third spacing switching roller 3 cut into or separate the tangent line 15 in an orderly manner.

[0032] The short shafts 5 are arranged in groups of two facing each other, and each group of two short shafts 5 are rotatably connected to be installed with spacing switching rollers of different specifications, so as to play a role of connecting the two ends of the spacing switching rollers.

[0033] Furthermore, two mounting holes 810 are symmetrically provided on the L-shaped plate 8 , and each mounting hole 810 is rotatably connected to the cylinder body of the first oil cylinder 10 via a rotating shaft.

[0034] Working principle: The line body part of the tangent line 15 leading into the end area and leading out of the end area is Figure 7 The distribution is in the form of ray distribution, and the tangent 15 of the ray distribution area is Figure 7 At A in Figure 7 The B in the figure is the linear body of the horizontal parallel slice; the first oil cylinder 10 is used to push and pull the second connecting rod 7 connected by the bearing 11, and the first connecting rod 6 located between the other ends of the two profile strips 4 is rotated and connected with the corresponding end of the L-shaped plate 8, so that the profile strip 4 and the first spacing switching roller 1, the second spacing switching roller 2 and the third spacing switching roller 3 connected thereto are all in a side rotation state, and at the same time, the second oil cylinder 14 is used to tilt the connected L-shaped plate 8 up and down along the guide rail 12, which plays a role in adjusting the horizontal movement position of each spacing switching roller, and provides an adjusting push-pull force for the corresponding intermediate ring groove on each spacing switching roller to contact the tangent 15 part;

[0035] Combination Figure 4 , Figure 5 and Figure 6 , respectively, the pitch adjustment of each pitch switching roller, which is not limited to the first pitch switching roller 1, the second pitch switching roller 2 and the third pitch switching roller 3 as a group, is performed on the tangent line 15 pitch, as follows:

[0036] by Figure 4Taking the initial state of the spacing adjustment of the tangent 15 as an example, when the tangent 15 needs to be switched from the third spacing switching roller 3 to each second intermediate ring groove 210 of the second spacing switching roller 2, the first oil cylinder 10 extends and pushes the profile plate 4 connected by the second connecting rod 7 to rotate downward, so that the third spacing switching roller 3 gradually separates from the tangent 15, the second spacing switching roller 2 gradually contacts the tangent 15, and the third spacing switching roller 3 and the tangent 15 are critically separated, and at the same time, the second spacing switching roller 2 and the tangent 15 are just critically contacted, until the tangent 15 is located in the corresponding second intermediate ring groove 210 on the second spacing switching roller 2;

[0037] When it is necessary to switch the tangent 15 from the second pitch switching roller 2 to each first intermediate ring groove 110 of the first pitch switching roller 1, the first oil cylinder 10 is in the extended state again, pushing the profile plate 4 connected by the second connecting rod 7 to rotate downward, so that the second pitch switching roller 2 gradually separates from the tangent 15, the first pitch switching roller 1 gradually contacts with the tangent 15, and the second pitch switching roller 2 and the tangent 15 are critically separated, and the first pitch switching roller 1 and the tangent 15 are just critically contacted, until the tangent 15 is located in the corresponding first intermediate ring groove 110 on the first pitch switching roller 1;

[0038] In summary: by matching the parts of the tangent 15 in the radial distribution area with the intermediate ring grooves on each spacing switching roller, and combining with the adjustment mechanism, the spacing of the tangent 15 can be adjusted accurately and quickly, which can meet the production and processing needs of slicing materials of different thicknesses, greatly shorten the operation time of the traditional method for arranging the position of the tangent 15, and has high efficiency. The spacing adjustment of the tangent 15 is completed by alternating with the critical cutting-in and separation of the tangent 15 between each spacing switching roller, and the distribution state of the first intermediate ring groove 110, the distribution state of the second intermediate ring groove 210 and the distribution state of the third intermediate ring groove 310 are respectively matched with the line spacing of the tangent 15 parts in the radial distribution area in sequence and in an orderly manner, thereby improving the accuracy of the tangent 15 spacing adjustment position, and ensuring that each tangent 15 part is accurately located in the corresponding intermediate ring groove.
