[0023] Please see Figure 1-3 This utility model provides a technical solution: a plate feeding mechanism for a plate rolling machine, including a left roller conveyor belt, a right roller conveyor belt and a limiting component 8;

[0024] The left roller conveyor belt includes a left frame 1 and a left roller 2. Several left bearing seats 3 are symmetrically arranged on the upper surfaces of both sides of the left frame 1. There are several left rollers 2, and each of them is connected to the corresponding left bearing seat 3.

[0025] The right-side roller conveyor belt includes a right-side frame 4 and a right-side roller 5. Several right-side bearing seats 6 are symmetrically arranged on the upper surfaces of both sides of the right-side frame 4. There are several right-side rollers 5, each of which is connected to the corresponding right-side bearing seat 6. The right-side frame 4 and the left-side frame 1 are connected to each other by several connecting frames 7. The horizontal height of the top of the left-side roller 2 and the right-side roller 5 is greater than the horizontal height of the top of the left-side bearing seat 3 and the right-side bearing seat 6, so as to ensure that the left-side bearing seat 3 and the right-side bearing seat 6 should not be conveyed to the plate.

[0026] There are four limiting components 8, which are welded to the left frame 1 and the right frame 4 respectively. The limiting components 8 are arranged symmetrically in pairs, with two limiting components 8 connected to the ends of the left frame 1 and the right frame 4 respectively. Each limiting component 8 includes a housing 801, a first motor 802, a guide rod 803, a lead screw 804, a slider 805, and a push-limiting wheel 806. The upper surface of the housing 801 is open, and the first motor 802 is set at the outer end of the housing 801. Two guide rods 803 and one lead screw 804 are set inside the housing 801. The outer end of the lead screw 804 is connected to the output shaft of the first motor 802. The slider 805 is guided and engaged with the guide rod 803. The slider 805 is also engaged with the lead screw 804 through a lead screw nut pair. Two push-limiting wheels 806 are set on the upper surface of the slider 805. A second motor 1 is set inside the left frame 1 and the right frame 4 respectively. 0. The output shaft of the second motor 10 is equipped with a drive sprocket 11. One end of the left roller 2 and the right roller 5 is equipped with a double-row sprocket 9. The adjacent left roller 2 and the adjacent right roller 5 are linked together by the double-row sprocket 9 and the chain. The drive sprocket 11 of the second motor 10 located in the left frame 1 is connected to the double-row sprocket 9 of the corresponding left roller 2 through the chain. The drive sprocket 11 of the second motor 10 located in the right frame 4 is connected to the double-row sprocket 9 of the corresponding right roller 5 through the chain. The drive sprocket 11 of the second motor 10 and the chain drive the corresponding left roller 2 or right roller 5 to rotate. Then, through the cooperation of the double-row sprocket 9 and the chain, the left roller 2 and the right roller 5 are rotated, thereby realizing the conveying of the plate. The height of the shell 801 is the same as the height of the left frame 1 and the right frame 4 to ensure that the shell 801 does not affect the conveying of the plate.

[0027] The horizontal height of the top of the left roller 2 and the right roller 5 is greater than the horizontal height of the bottom of the push-limit wheel 806, and the horizontal height of the top of the left roller 2 and the right roller 5 is less than the horizontal height of the top of the push-limit wheel 806. This ensures that after the board is supported on the left roller 2 and the right roller 5, the push-limit wheel 806 can smoothly abut against the edge of the board, thereby realizing the adjustment of the angle and position of the board.

[0028] Both the left frame 1 and the right frame 4 are composed of a long side plate 12, a middle side plate 13, a short side plate 14, and several connecting rods 15. The long side plate 12 is connected to the middle side plate 13 and the short side plate 14 through the connecting rods 15. The middle side plate 13 and the short side plate 14 are located on the same vertical plane. The two sides of one of the housings 801 are respectively connected to the middle side plate 13 and the short side plate 14. The left frame 1 and the right frame 4 of this structure can realize the installation of a limiting component 8 between the middle side plate 13 and the short side plate 14, thereby facilitating the adjustment of the plate.

[0029] Installation method and operating principle: Connect the slider 805 with the push-limit wheel 806 to the two guide rods 803 and the lead screw 804 respectively. Install the guide rods 803 and the lead screw 804 inside the housing 801 of the limiting assembly 8. Install the first motor 802 at one end of the housing 801 and connect it to the lead screw 804 through a coupling. The other end of the lead screw 804 is supported inside the housing 801 by a lead screw seat, thus completing the assembly of the limiting assembly 8. Connect the long side plate 12 to the middle side plate 13 and the short side plate 14 through the connecting rod 15. Weld the housing 801 of one of the limiting assemblies 8 to the middle side plate 13 and the short side plate 14 respectively. Weld the housing 801 of the other limiting assembly 8 to the other end of the short side plate 14, thus completing the connection between the limiting assembly 8 and the left and right roller conveyor belts. Finally, connect the left roller 2 to the left frame 1 via the left bearing seat 3, and connect the right roller 5 to the right frame 4 via the right bearing seat 6. At the same time, connect adjacent left rollers 2 to each other via double-row sprockets 9 and chains, and connect adjacent right rollers 5 to each other via double-row sprockets 9 and chains. Install the two second motors 10 in the left frame 1 and the right frame 4 respectively, and connect the drive sprockets 11 on the output shaft of the second motors 10 to the double-row sprockets 9 of the left roller and the double-row sprockets 9 of the right roller respectively via chains. Finally, connect the left frame 1 and the right frame 4 via the connecting frame 7 to complete the installation. In use, the first motor 802 drives the lead screw 804 to rotate. The lead screw 804 engages with the lead screw nut of the slide block, causing the slide block to move to the outer end. The sheet material is placed on the left roller 2 and the right roller 5. Through the synchronous drive of the two second motors 10, the sheet material moves backward along the left roller 2 and the right roller 5. When the sheet material reaches the end, the pushing and limiting wheels 806 of the four limiting components 8 push against each other to determine the feeding position and angle of the sheet material, thereby realizing the feeding of the sheet material. Figure 4 As shown, after the rhomboid sheet reaches the end, its angle and position are adjusted by four sets of push-limiting wheels 806. The solid line in the figure represents the position of the sheet when it reaches the end, and the dashed line represents the feeding state of the sheet after the position is adjusted. This utility model has a reasonable structure. The sheet is supported and conveyed by the left roller 2 of the left roller conveyor belt and the right roller 5 of the right roller conveyor belt. The limiting components 8 connected to the left frame 1 and the right frame 4, and the push-limiting wheels 806 of each limiting component 8, realize the lateral positioning and angle adjustment of the sheet. Even for non-rectangular sheet materials, the angle can be adjusted smoothly before feeding, greatly improving flexibility and applicability.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
