DETAILED DESCRIPTION

[0023] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0024] See Figures 1 to 4 As shown, a plate shearing and feeding guide mechanism includes a workbench 1, a guide platform 2 is installed on the front side of the workbench 1, and a guide unit is provided above the guide platform 2, and the plate is guided by the guide unit to ensure that the subsequent plate is in the middle position when cutting, thereby realizing symmetrical cutting of the plate, and the guide unit includes two slots 3 symmetrically opened on the left and right sides of the guide platform 2, and the inner cavities of the two slots 3 are penetrated by a first moving rod 6 and a second moving rod 15, and the first moving rod 6 and the second moving rod 15 move equidistantly in relative directions, and a first base 16 is fixedly installed on the second moving rod 15, and a second base 17 is fixedly installed on the first moving rod 6, and the second base 17 and the first base 17 are symmetrically arranged with respect to the left and right sides of the workbench 1, and guide plates 18 are respectively vertically and fixedly installed on the top ends of the first base 16 and the second base 17, and the first base 16 and the second base 17 move equidistantly relative to each other, thereby realizing precise centering guidance of plate feeding, thereby ensuring that the subsequent plate is cut in the center.

[0025] Specific reference Figure 3 and Figure 4 As shown, the first base 16 is slidably mounted on the first moving rod 6, and the second base 17 is slidably mounted on the second moving rod 15. When the first moving rod 6 moves, it can drive the second base 17 to slide along the outer wall of the second moving rod 15. When the second moving rod 15 moves, it can drive the first base 16 to move along the outer wall of the first moving rod 6. This ensures that when the first moving rod 6 and the second moving rod 15 respectively drive the second base 17 and the first base 16 to move, no interference will occur. When the first base 16 and the second base 17 move, they can drive the guide plates 18 connected to the top ends to move synchronously, thereby realizing the synchronous centering adjustment of the distance between the two guide plates 18.

[0026] See Figure 4As shown, a supporting plate 4 is installed on the right side wall of the guide platform 2, and a first cylinder 5 is installed on the supporting plate 4. The output end of the first cylinder 5 is connected to the first moving rod 6, and a first moving seat 7 is fixedly installed on the first moving rod 6. A second moving seat 14 is fixedly installed on the second moving rod 15. A fixed plate 8 is fixedly installed on the inner wall of the right side groove body 3, and a swing plate 9 is rotatably connected to the fixed plate 8. The outer wall of the swing plate 9 is respectively provided with a first through groove 10 and a second through groove 12. The first moving pin 11 is slidably embedded in the inner cavity of the first through groove 10, and the first moving pin 11 is connected to the first moving seat 7, and the second moving pin 13 is slidably embedded in the inner cavity of the second through groove 12, and the second moving pin 13 is connected to the second moving seat 14. The first cylinder 5 is driven by the opening The first moving rod 6 and the first moving seat 7 are moved synchronously to the left. At this time, the first moving pin 11 moves along the first through slot 10 and prompts the swing plate 9 to rotate clockwise, prompting the second moving pin 13 to move along the inner cavity of the second through slot 12, and the second moving pin 13 is driven to the right by the swing plate 9, that is, under the rotation of the swing plate 9, the second moving pin 13 and the first moving pin 11 are moved equidistantly in opposite directions, thereby realizing the equidistant movement of the second moving seat 14 and the first moving seat 7 in opposite directions, and then realizing the equidistant movement of the second moving rod 15 and the first moving rod 6 in opposite directions, and then realizing the synchronous equidistant movement between the two guide plates 18, and realizing the centered guided loading of the plate.

[0027] See Figure 4 The middle part of the swing plate 9 is rotatably connected to the fixed plate 8 through a pin shaft, and the first through slot 10 and the second through slot 12 are symmetrically arranged relative to the center of the swing plate 9, thereby ensuring that when the swing plate 9 rotates, it can drive the first movable pin 11 and the second movable pin 13 in the inner cavity of the first through slot 10 and the second through slot 12 to move equidistantly.

[0028] See Figure 1 and Figure 2 As shown, vertical plates 19 are symmetrically provided on the left and right sides of the upper surface of the workbench 1, and second cylinders 20 are respectively installed on the side walls of the two vertical plates 19. The output end of the second cylinder 20 is connected to a bracket 21, and a rotating shaft 22 is rotatably provided in the bracket 21. A cutting blade 23 is fixedly installed on the rotating shaft 22. A motor 24 is installed on the bracket 21, and the output end of the motor 24 is connected to the rotating shaft 22. The rotating shaft 22 and the cutting blade 23 are driven to rotate synchronously by the turned-on motor 24, and the turned-on second cylinder 20 drives the bracket 21 to move downward, so that the cutting blade 23 is prompted to gradually move downward toward the plate, thereby realizing centered cutting of the plate.

[0029] Specifically, the cutting blade 23 is located in the middle of the workbench 1, and the two guide plates 18 are symmetrically arranged relative to the cutting blade 23, thereby satisfying the equidistant movement of the first base 16 and the second base 17 in relative directions, ensuring that the first base 16 and the second base 17 are still symmetrical relative to the cutting blade 23 after the spacing is adjusted, and ensuring that the two guide plates 18 are still symmetrically arranged relative to the cutting blade 23 after the position is adjusted.

[0030] Columns 25 are installed at the four corners of the bottom end of the workbench 1, and universal wheels 26 are installed at the bottom ends of the columns 25. The columns 25 can support the entire workbench 1, and the universal wheels 26 can move and transport the entire equipment.

[0031] It is worth noting that the first cylinder 5 and the second cylinder 20 used in this application are self-locking cylinders commonly used on the market, and their output ends can stay at any position and be locked; the motor 24 adopts a self-locking motor with a locked output end commonly used on the market, and its output end can self-lock when it stops working and will not rotate under external force; the above-mentioned existing components will not be described in detail here.

[0032] The working principle of the plate shearing and feeding guide mechanism in this embodiment is as follows:

[0033] The plate is placed between the two guide plates 18, and the first cylinder 5 is turned on to drive the first moving rod 6 and the first moving seat 7 to move synchronously to the left. At this time, the first moving pin 11 moves along the first through slot 10, and prompts the swing plate 9 to rotate clockwise, prompting the second moving pin 13 to move along the inner cavity of the second through slot 12, and realizes that the second moving pin 13 moves to the right under the driving action of the swing plate 9, that is, under the rotation action of the swing plate 9, the second moving pin 13 and the first moving pin 11 are moved equidistantly in opposite directions, thereby realizing the equidistant movement of the second moving seat 14 and the first moving seat 7 in opposite directions, and then realizing the second moving rod 15 and the first moving rod 6 performs equidistant movement in opposite directions; since the second moving rod 15 is fixedly connected to the first base 16, and the first moving rod 6 is fixedly connected to the second base 17, the relative movement of the second moving rod 15 and the first moving rod 6 causes the second base 17 and the first base 16 to perform equidistant movement in opposite directions, thereby achieving the synchronous movement of the guide plates 18 respectively installed on the top ends of the first base 16 and the second base 17 toward the middle; since the second base 17 and the first base 16 are symmetrical relative to the cutting blade 23, the two guide plates 18 are arranged symmetrically relative to the cutting blade 23 after adjustment, ensuring that the plate can be loaded in the center under the guiding and limiting action of the two guide plates 18;

[0034] The plate moves backward under the restraining action of the two guide plates 18, and the motor 24 drives the rotating shaft 22 and the cutting blade 23 to rotate synchronously. The second cylinder 20 drives the bracket 21 downward, causing the cutting blade 23 to gradually move downward toward the plate, thereby achieving a centered cut on the plate.

[0035] The present invention can accurately guide the loading of the plate, ensure that the plate is symmetrical with respect to the cutting blade 23 when loading, realize the left-right symmetrical shearing of the plate, and do not require additional manual measurement and adjustment steps, ensuring that the symmetrical and centered cutting of the plate is carried out quickly and effectively. It is more suitable for the processing needs of batch centered cutting of plates, and can adjust the distance between the first base 16 and the second base 17, and flexibly adapt to the feeding and guiding needs of plates of different widths.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
