Description

Technical Field

[0001] This invention relates to the field of coil shearing technology, and in particular to a fully automatic edge shearing machine for metal coils. Background Technology

[0002] The edge material of metal coils is usually cut to the required length using a shearing machine, and the straightness of the cut edge material affects its accuracy in use.

[0003] For example, patent document CN207464303U discloses a shearing device for a slitting machine, including a conveying platform with multiple parallel guide rollers. A flattening assembly is provided at one end of the conveying platform's feed inlet, used to flatten the metal coil to be slit on the conveying platform. The flattening assembly includes an upper pressure roller and a lower pressure roller. However, after flattening the metal coil edge material using this flattening assembly, the internal stress of the metal coil edge material is not completely eliminated, and elastic recovery still causes curling, resulting in poor flattening effect. Summary of the Invention

[0004] Therefore, it is necessary to provide a fully automatic metal coil edge shearing machine to address the technical problem of poor flattening effect of current shearing devices on metal coil edge material.

[0005] The above objectives are achieved through the following technical solutions:

[0006] An automatic edge shearing machine for metal coils includes a shearing box. Inside the shearing box, a flattening assembly and a shearing assembly are arranged sequentially from front to back. The flattening assembly includes a feeding roller group and at least four rotating roller groups arranged sequentially from front to back. The feeding roller group includes an upper feeding roller and a lower feeding roller that rotate synchronously in opposite directions, and the upper and lower feeding rollers are corresponding and in contact in the vertical direction. Each rotating roller group includes an upper rotating roller and a lower rotating roller that rotate synchronously in opposite directions, and the upper and lower rotating rollers are corresponding and in contact in the vertical direction. The interval between the upper and lower rollers in each roller group gradually decreases from front to back, thereby flattening the edge material of the metal coil. The length of the upper roller in each roller group gradually decreases from front to back. The lengths of the upper feed roller, lower feed roller, upper roller, and lower roller all extend in the left-right direction. The upper feed roller rotates synchronously with each upper roller and in the same direction, and the lower feed roller rotates synchronously with each lower roller and in the same direction. The shearing assembly is used to segment the edge material of the metal coil.

[0007] Furthermore, the shearing box is provided with an upper support plate and a lower support plate distributed in the vertical direction. Both the upper support plate and the lower support plate are inclined. Multiple upper limit plates are arranged at intervals in the front-back direction on the upper support plate. Each upper roller can extend downward from the interval between two adjacent upper limit plates. Multiple lower limit plates are arranged at intervals in the front-back direction on the lower support plate. Each lower roller can extend upward from the interval between two adjacent lower limit plates.

[0008] Furthermore, the shearing box is also equipped with a drive mechanism, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, and a fourth transmission mechanism. The upper feed roller and the lower feed roller are driven together by the first transmission mechanism. The upper rotating roller and the lower rotating roller in the same rotating roller group are driven together by the second transmission mechanism. The lower feed roller and the adjacent lower rotating roller are driven together by the third transmission mechanism. The two adjacent lower rotating rollers are driven together by the fourth transmission mechanism. The drive mechanism can drive the upper feed roller to rotate.

[0009] Furthermore, the number of roller sets is seven.

[0010] Furthermore, the four roller groups located at the rear include at least two roller brush groups and at least one flattening roller group. The upper and lower rollers in the roller brush group are both roller brushes, which can guide the metal coil edge material to move backward through friction. The upper and lower rollers in the flattening roller group are both steel rollers, which can flatten the metal coil edge material.

[0011] Furthermore, the first, second, third, and fourth transmission mechanisms are all gear transmission mechanisms. The first transmission mechanism includes a first gear and a second gear, with the first gear coaxially located at the right end of the upper feed roller and the second gear coaxially located at the right end of the lower feed roller, and the first gear meshing with the second gear. The second transmission mechanism includes a third gear and a fourth gear, with the third gear coaxially located at the right end of the upper rotating roller and the fourth gear coaxially located at the right end of the lower rotating roller, and the third gear meshing with the fourth gear. The third transmission mechanism includes a fifth gear and a sixth gear, with the fifth gear coaxially located at the left end of the lower feed roller and the sixth gear coaxially located at the left end of the lower rotating roller, and the fifth gear meshing with the sixth gear. The fourth transmission mechanism includes a seventh gear, which is located between two adjacent sixth gears and meshes with both adjacent sixth gears simultaneously.

[0012] Furthermore, the four rear roller groups are all rubber roller groups, and the upper and lower rollers in the rubber roller groups are both rubber rollers; the second transmission mechanism between the upper and lower rollers in the same rubber roller group is a first conical wheel transmission mechanism, and the fourth transmission mechanism between the lower rollers of two adjacent rubber roller groups is a second conical wheel transmission mechanism. The first conical wheel transmission mechanism includes a first speed regulating structure, which can adjust the difference in linear speed between the upper and lower rollers in the same rubber roller group. The second conical wheel transmission mechanism includes a second speed regulating structure, which can adjust the difference in linear speed between the lower rollers in two adjacent rubber roller groups.

[0013] Furthermore, from front to back, the four rubber roller groups are the first rubber roller group, the second rubber roller group, the third rubber roller group, and the fourth rubber roller group. The linear velocity of the lower roller in the first rubber roller group, the second rubber roller group, and the third rubber roller group gradually increases. The linear velocity of the lower roller in the fourth rubber roller group is greater than or equal to the linear velocity of the lower roller in the third rubber roller group. Moreover, the linear velocities of the upper roller and the lower roller in the same rubber roller group are the same.

[0014] Furthermore, from front to back, the four rubber roller groups are the first rubber roller group, the second rubber roller group, the third rubber roller group, and the fourth rubber roller group. The linear velocities of the lower rollers in the first, second, and third rubber roller groups are the same and all less than the linear velocities of the lower rollers in the fourth rubber roller group. The linear velocities of the upper rollers in the first rubber roller group are greater than the linear velocities of the lower rollers. The linear velocities of the upper rollers in the second rubber roller group are less than the linear velocities of the lower rollers. The linear velocities of the upper rollers and lower rollers in the third and fourth rubber roller groups are the same.

[0015] Furthermore, the first conical gear transmission mechanism includes a first conical gear and a second conical gear. The first conical gear is coaxially disposed at the right end of the upper rotating roller, and the second conical gear is coaxially disposed at the right end of the lower rotating roller. The conical base surfaces of the first and second conical gears face opposite directions. The first speed regulating structure is located between the first and second conical gears. The first speed regulating structure includes a first screw, which is threadedly connected to the shear box. Two first speed regulating wheels are rotatably disposed at the end of the first screw. The two first speed regulating wheels are radially distributed along the first screw and are in frictional transmission engagement with each other. One of the first speed regulating wheels is in frictional transmission with the first conical gear. In conjunction with this, another first speed-regulating wheel engages with the second conical wheel through friction transmission; the second conical wheel transmission mechanism includes a third conical wheel and a fourth conical wheel, with the third conical wheel coaxially disposed at the left end of the lower rotating roller; the fourth conical wheel is located between two adjacent third conical wheels, with the conical bottom surfaces of the third and fourth conical wheels facing opposite directions, and the second speed-regulating structure is located between the adjacent third and fourth conical wheels; the second speed-regulating structure includes a second screw, which is threadedly connected to the shear box, and a second speed-regulating wheel is coaxially rotatably disposed at the end of the second screw, which simultaneously engages with both the third and fourth conical wheels through friction transmission.

[0016] The beneficial effects of this invention are:

[0017] The fully automatic metal coil edge shearing machine provided by the present invention allows the metal coil edge material to enter between the upper and lower feed rollers, and then move from front to back between the upper and lower rotating rollers. As the interval between the upper and lower rotating rollers gradually decreases, the metal coil edge material is gradually flattened, which can improve the flattening effect of the metal coil edge material.

[0018] Secondly, the four rear roller groups are all configured as rubber roller groups. Through a first speed control structure and a second speed control structure, the four rear rubber roller groups can operate in either a first speed mode or a second speed mode. The first speed mode causes the metal coil edge material to be stretched multiple times along the moving direction, while the second speed mode allows the metal coil edge material to be concave and convex, and stretched. Both modes can eliminate the internal stress memory of the metal coil edge material, further improving the flattening effect of the metal coil edge material. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0042] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] like Figures 1 to 10 As shown, an embodiment of the present invention provides a fully automatic metal coil edge shearing machine, including a shearing box 300. Inside the shearing box 300, a flattening assembly 100 and a shearing assembly 200 are arranged sequentially from front to back. The flattening assembly 100 includes a feeding roller group and at least four rotating roller groups arranged sequentially from front to back. The feeding roller group includes an upper feeding roller 101 and a lower feeding roller 102 that rotate synchronously in opposite directions. The upper feeding roller 101 and the lower feeding roller 102 are corresponding and contacting each other in the vertical direction, thereby guiding the metal coil edge material into each rotating roller group. Each rotating roller group includes an upper rotating roller 103 and a lower rotating roller 104 that rotate synchronously in opposite directions. The upper rotating roller 103 and the lower rotating roller 104 are corresponding and spaced apart in the vertical direction. The interval between the upper rotating roller 103 and the lower rotating roller 104 in each rotating roller group gradually decreases from front to back, thereby enabling the flattening of the metal coil edge material. The upper feed roller 101, lower feed roller 102, upper rotating roller 103, and lower rotating roller 104 all extend in the left-right direction. The length of the upper rotating roller 103 in each roller group gradually decreases from front to back, thus guiding the centering of the metal coil edge material. The upper feed roller 101 rotates synchronously with each upper rotating roller 103 in the same direction, and the lower feed roller 102 rotates synchronously with each lower rotating roller 104 in the same direction. The shearing assembly 200 is used to segment and cut the metal coil edge material.

[0045] With this setup, the metal coil edge material enters between the upper feed roller 101 and the lower feed roller 102, and then moves from front to back between the upper rotating roller 103 and the lower rotating roller 104. At the same time, as the interval between the upper rotating roller 103 and the lower rotating roller 104 gradually decreases, the metal coil edge material is gradually flattened, which can improve the flattening effect of the metal coil edge material.

[0046] like Figure 5 As shown, the shearing box 300 has two side plates 305 inside, and the upper feed roller 101, lower feed roller 102, upper rotating roller 103, and lower rotating roller 104 are all rotatably mounted on the side plates 305. The shearing box 300 has an inlet and an outlet. The inlet corresponds to the space between the upper feed roller 101 and the lower feed roller 102, and the outlet corresponds to the space between the upper rotating roller 103 and the lower rotating roller 104.

[0047] like Figure 3 and Figure 4 As shown, the shearing assembly 200 includes a shearing blade 204 and a shearing motor 201. The output end of the shearing motor 201 is provided with a coupling sleeve 202. The coupling sleeve 202 is engaged with the shearing blade 204 through a key 205 to prevent rotation, so that the rotation of the shearing motor 201 drives the shearing blade 204 to rotate. The coupling sleeve 202 is rotatably mounted on the shearing box 300 through a bearing 203.

[0048] like Figure 10 As shown, the shearing box 300 is provided with an upper support plate 301 and a lower support plate 302 distributed along the vertical direction. Both the upper support plate 301 and the lower support plate 302 are inclined. Multiple upper limit plates 303 are spaced apart along the front-back direction on the upper support plate 301, and each upper roller 103 can extend downward from the gap between two adjacent upper limit plates 303. Multiple lower limit plates 304 are spaced apart along the front-back direction on the lower support plate 302, and each lower roller 104 can extend upward from the gap between two adjacent lower limit plates 304. This arrangement facilitates control of the interval between the upper roller 103 and the lower roller 104 in each roller group.

[0049] Furthermore, the shearing box 300 is also provided with a drive mechanism, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, and a fourth transmission mechanism. The upper feed roller 101 and the lower feed roller 102 are driven together by the first transmission mechanism. The upper rotating roller 103 and the lower rotating roller 104 of the same rotating roller group are driven together by the second transmission mechanism. The lower feed roller 102 and the adjacent lower rotating roller 104 are driven together by the third transmission mechanism. The two adjacent lower rotating rollers 104 are driven together by the fourth transmission mechanism. The drive mechanism can drive the upper feed roller 101 to rotate.

[0050] Furthermore, the number of roller groups is seven. In other embodiments, five, eight, etc., may be provided.

[0051] Furthermore, the four rear roller groups include at least two brush groups and at least one flattening roller group. The upper roller 103 and lower roller 104 in the brush groups are both brushes, which guide the metal coil edge material backward through friction. The upper roller 103 and lower roller 104 in the flattening roller group are both steel rollers, which flatten the metal coil edge material. This ensures the flattening of the metal coil edge material and facilitates its smoother movement.

[0052] When there are seven roller sets, except for the four roller sets at the rear, the remaining roller sets are all flattening roller sets, thus ensuring the pressing effect on the edge material of the metal coil.

[0053] like Figures 5 to 9As shown, the first, second, third, and fourth transmission mechanisms are all gear transmission mechanisms. The first transmission mechanism includes a first gear 105 and a second gear 106. The first gear 105 is coaxially located at the right end of the upper feed roller 101, and the second gear 106 is coaxially located at the right end of the lower feed roller 102. The first gear 105 meshes with the second gear 106. The second transmission mechanism includes a third gear 110 and a fourth gear 111. The third gear 110 is coaxially located at the right end of the upper rotary roller 103, and the fourth gear 111... 11 is coaxially located at the right end of the lower roller 104, and the third gear 110 meshes with the fourth gear 111; the third transmission mechanism includes a fifth gear 107 and a sixth gear 108, the fifth gear 107 is coaxially located at the left end of the lower feed roller 102, and the sixth gear 108 is coaxially located at the left end of the lower roller 104, and the fifth gear 107 meshes with the sixth gear 108; the fourth transmission mechanism includes a seventh gear 109, the seventh gear 109 is located between two adjacent sixth gears 108, and meshes with two adjacent sixth gears 108 simultaneously.

[0054] Specifically, a rotating rod 116 is provided between two adjacent lower rotating rollers 104. The rotating rod 116 is arranged parallel to the lower rotating rollers 104 and is rotatably positioned between the left and right side plates 305, thereby supporting the left and right side plates 305. The seventh gear 109 is coaxially located at the left end of the rotating rod 116.

[0055] The shearing box 300 is also equipped with a drive mechanism, which is a drive motor (not shown in the figure). The drive motor is in transmission cooperation with the left end of the upper feed roller 101.

[0056] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows:

[0057] The drive motor is controlled to rotate, causing the upper feed roller 101 to rotate. The upper feed roller 101 then drives the lower feed roller 102 to rotate synchronously in the opposite direction. The lower feed roller 102 drives each lower rotating roller 104 to rotate synchronously in the same direction. Simultaneously, the lower rotating roller 104 drives the upper rotating roller 103 of the same roller group to rotate synchronously in the opposite direction. Then, the shearing motor 201 is turned on, causing the shearing blade 204 to rotate. Simultaneously, the metal coil edge material enters between the upper feed roller 101 and the lower feed roller 102, moving from front to back between the upper rotating roller 103 and the lower rotating roller 104. During this movement, it gradually centers itself and is flattened by the upper rotating roller 103 and the lower rotating roller 104, thus straightening the metal coil edge material. When it reaches the position of the shearing blade 204, the shearing blade 204 cuts the metal coil edge material to the required length.

[0058] like Figures 11 to 20 As shown, another embodiment of the present invention provides a fully automatic edge shearing machine for metal coils, which differs from the above embodiment in that:

[0059] The four roller groups located at the rear are all rubber roller groups, and the upper roller 103 and the lower roller 104 in the rubber roller group are both rubber rollers. The second transmission mechanism between the upper roller 103 and the lower roller 104 in the same rubber roller group is a first conical wheel transmission mechanism, and the fourth transmission mechanism between the lower rollers 104 of two adjacent rubber roller groups is a second conical wheel transmission mechanism. The first conical wheel transmission mechanism includes a first speed regulating structure 500, which can adjust the difference in linear speed between the upper roller 103 and the lower roller 104 in the same rubber roller group. The second conical wheel transmission mechanism includes a second speed regulating structure 400, which can adjust the difference in linear speed between the lower rollers 104 in two adjacent rubber roller groups.

[0060] Specifically, in the first speed mode, from front to back, the four rubber roller groups are the first rubber roller group, the second rubber roller group, the third rubber roller group, and the fourth rubber roller group. The linear speed of the lower roller 104 in the first rubber roller group, the second rubber roller group, and the third rubber roller group gradually increases. The linear speed of the lower roller 104 in the fourth rubber roller group is greater than or equal to the linear speed of the lower roller 104 in the third rubber roller group. In the same rubber roller group, the linear speed of the upper roller 103 and the lower roller 104 is the same.

[0061] The linear velocity of the lower roller 104 in the fourth rubber roller group is proportional to the rotational speed of the shearing blade 204, thereby ensuring that the required length can be cut.

[0062] When the metal coil edge material enters the second rubber roller group from the first rubber roller group, the linear velocity of the lower roller 104 in the second rubber roller group is greater than that in the first rubber roller group. Therefore, the second rubber roller group stretches the metal coil edge material along its length, allowing it to eliminate its own stress. Similarly, the third rubber roller group also stretches the metal coil edge material along its length. When the linear velocity of the lower roller 104 in the fourth rubber roller group is greater than that in the third rubber roller group, the fourth rubber roller group also stretches the metal coil edge material along its length. When the linear velocity of the lower roller 104 in the fourth rubber roller group is equal to that in the third rubber roller group, the fourth rubber roller group does not stretch the metal coil edge material. This allows the metal coil edge material to be stretched multiple times along its length, thereby eliminating the internal stress memory in the metal coil edge material, making it less prone to rebound, and resulting in a better flattening effect. The first speed mode is suitable for metal coil edge materials that can be stretched.

[0063] Specifically, in the second speed mode, from front to back, the four rubber roller groups are the first rubber roller group, the second rubber roller group, the third rubber roller group, and the fourth rubber roller group. The linear speed of the lower roller 104 in the first rubber roller group, the second rubber roller group, and the third rubber roller group is the same and is all less than the linear speed of the lower roller 104 in the fourth rubber roller group. The linear speed of the upper roller 103 in the first rubber roller group is greater than the linear speed of the lower roller 104. The linear speed of the upper roller 103 in the second rubber roller group is less than the linear speed of the lower roller 104. The linear speeds of the upper roller 103 and the lower roller 104 in the third rubber roller group and the fourth rubber roller group are the same.

[0064] When the metal coil edge material enters the first rubber roller group, the linear velocity of the upper roller 103 in the first rubber roller group is greater than that of the lower roller 104, causing the upper surface of the metal coil edge material to elongate relative to the lower surface. According to the bending principle in material mechanics, the metal coil edge material will bend towards the side with less elongation, thus bending downwards (i.e., concave). When the metal coil edge material enters the second rubber roller group from the first rubber roller group, the linear velocity of the upper roller 103 in the second rubber roller group is less than that of the lower roller. The linear speed of 104 causes the metal coil edge material to bend upwards (i.e., convex upwards), thereby eliminating the internal stress memory of the metal coil edge material. It then enters the third and fourth rubber roller groups. Because the linear speeds of the upper roller 103 and lower roller 104 in the third and fourth rubber roller groups are the same, and the linear speed of the lower roller 104 in the fourth rubber roller group is greater than that in the third rubber roller group, the metal coil edge material can be flattened, further improving the flattening effect. This second speed mode is suitable for situations where the metal coil edge material itself is difficult to stretch, or where it is necessary to maintain the thickness or width of the metal coil edge material.

[0065] like Figure 11 As shown, the first conical wheel transmission mechanism includes a first conical wheel 112 and a second conical wheel 113. The first conical wheel 112 is coaxially disposed at the right end of the upper rotating roller 103, and the second conical wheel 113 is coaxially disposed at the right end of the lower rotating roller 104. The conical bottom surfaces of the first conical wheel 112 and the second conical wheel 113 face opposite directions.

[0066] like Figures 18 to 20The first speed regulating structure 500 is located between the first conical wheel 112 and the second conical wheel 113. The first speed regulating structure 500 includes a first screw 501, which is threaded onto the shear box 300. Two first speed regulating wheels 503 are rotatably mounted at the end of the first screw 501. These two wheels are radially distributed along the first screw 501 and engage in frictional transmission. One wheel engages with the first conical wheel 112, and the other engages with the second conical wheel 113. The first screw 501 has an axially extending locking groove 504. A locking screw 505 engages with the locking groove 504, locking the first screw 501 onto the shear box 300 and preventing rotation. The first screw 501 also has a first handwheel 502 for convenient rotation.

[0067] When it is necessary to adjust the linear speed difference between the upper roller 103 and the lower roller 104 in the same rubber roller group, pull out the locking screw 505 from the locking groove 504, and then rotate the first screw 501 to adjust the position of the two first speed regulating wheels 503 between the first cone wheel 112 and the second cone wheel 113.

[0068] like Figure 16 and Figure 17 As shown, the second conical gear transmission mechanism includes a third conical gear 114 and a fourth conical gear 115. The third conical gear 114 is coaxially disposed at the left end of the lower rotating roller 104; the fourth conical gear 115 is located between two adjacent third conical gears 114, and is coaxially disposed on the rotating rod 116. The conical base surfaces of the third conical gear 114 and the fourth conical gear 115 face opposite directions. Figures 12 to 15 As shown, the second speed regulating structure 400 is located between the adjacent third cone wheel 114 and fourth cone wheel 115; the second speed regulating structure 400 includes a second screw 401, which is threadedly connected to the shear box 300, and a second speed regulating wheel 403 is coaxially rotatably provided at the end of the second screw 401, which simultaneously engages with the third cone wheel 114 and the fourth cone wheel 115 through friction transmission.

[0069] The second screw 401 is also equipped with a second handwheel 402, which facilitates the rotation of the second screw 401. A locking nut 404 is threaded onto the second screw 401, which locks the second screw 401 onto the shear box 300. The second speed regulating wheel 403 is rotatably mounted on the second screw 401 via a fixing screw 405.

[0070] A compression spring 600 is provided between the first cone wheel 112, the fourth cone wheel 115 and the wall of the shearing box 300. Since the conical bottom surfaces of the first cone wheel 112 and the fourth cone wheel 115 face the wall of the shearing box 300, the compression spring 600 makes it difficult for the first cone wheel 112 and the fourth cone wheel 115 to move in the left and right directions, so as not to squeeze the wall of the shearing box 300.

[0071] like Figure 16 The diagram shows the first state of the flattening assembly 100. When it is necessary to adjust the linear velocity difference between the lower rotating rollers 104 in the third and fourth rubber roller groups, the second screw 401 between the lower rotating rollers 104 of the third and fourth rubber roller groups can be rotated. Figure 17 The diagram shows the second state of the flattening assembly 100. The second screw 401, located at the rear, moves to a position where the third cone wheel 114 and the fourth cone wheel 115 are close to the wall of the shearing box 300. The second speed regulating wheel 403 corresponds to the large end of the fourth cone wheel 115 and the small end of the third cone wheel 114, thereby reducing the transmission ratio between the fourth cone wheel 115 and the third cone wheel 114, which in turn reduces the linear velocity difference between the lower roller 104 of the fourth rubber roller group and the lower roller 104 of the third rubber roller group.

[0072] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows:

[0073] First, the linear velocity difference between the upper roller 103 and the lower roller 104 in the four rubber roller groups behind are adjusted by rotating the first screw 501 and the second screw 401 respectively, as well as the linear velocity difference between the lower roller 104 in two adjacent rubber roller groups.

[0074] Then, control the drive motor to rotate, so that the upper feed roller 101, the lower feed roller 102, and each upper rotating roller 103 and lower rotating roller 104 rotate synchronously, so that the four rubber roller groups behind are in the first speed mode or the second speed mode.

[0075] Then, the shearing motor 201 is turned on, causing the shearing blade 204 to rotate. At the same time, the metal coil edge material enters between the upper feed roller 101 and the lower feed roller 102, and moves from front to back between the upper rotating roller 103 and the lower rotating roller 104. During the movement, the metal coil edge material gradually centers itself, and when it passes through the four rubber roller groups, the metal coil edge material can be concave, convex and stretched, thereby eliminating the internal stress memory of the metal coil edge material, thus achieving the straightening of the metal coil edge material. When it moves to the position of the shearing blade 204, the shearing blade 204 automatically cuts the metal coil edge material to the required length.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
