The pressing positioning platform 43 is fixedly connected in a horizontal direction on the moving part 421 of the pressing electric cylinder 42; the pressing plate 44 is slidably connected in a horizontal direction on the pressing positioning platform 43 through a pressing horizontal slide rail 46; the pressing plate 44 can ensure that the workpiece 1 is not in direct hard contact with the sand belt paper during the pressing process, can provide a certain buffer sliding action for the workpiece 1, can prevent the workpiece 1 from being directly in contact with the rapidly rotating sand belt paper, can ensure that the workpiece 1 is slowly pressed to the sand belt paper for grinding, can prevent the workpiece 1 from being damaged during grinding, can ensure the grinding accuracy, and can make the overall structure more simple and reasonable. The pressing limiting part 45 is arranged on the side of the pressing positioning platform 43 away from the conveying belt mechanism, and the pressing limiting part 45 is used to block the pressing plate 44 during edge grinding. In this embodiment, the pressing limiting part 45 is a pressing line limiting block, and a left-right direction pressing limiting column is arranged on the pressing line limiting block to realize limiting. A plurality of pressing guide wheels 47 are arranged on one side of the pressing plate 44 close to the conveying belt mechanism, and the pressing guide wheels 47 are arranged in a horizontal direction and are flush with each other. The pressing electric cylinder 42 in the pressing assembly drives the pressing plate 44 on the pressing positioning platform 43 to press against the workpiece 1, and can press the workpiece 1 against the sand belt paper, and through the pressing guide wheels 47, the workpiece 1 can be continuously conveyed to the discharge end during grinding, which greatly improves the grinding efficiency and can also be conveyed to the specified position and stopped for workpiece grinding before conveying.

[0046] As shown in the figure, Figure 6 A gap baffle 48 is arranged between the two adjacent pressing guide wheels 47 on the pressing plate 44; the gap baffle 48 is used to prevent the workpiece 1 from being clamped into the gap between the two adjacent pressing guide wheels 47; through the gap baffle 48, it can prevent the end of the workpiece 1 from being clamped into the gap between the two adjacent pressing guide wheels 47 during pressing and grinding, ensure that the workpiece 1 is horizontally and stably conveyed and ground, and ensure the grinding effect. All the gap baffles 48 are in the same plane, and the gap baffles 48 are located inside the contact end of the pressing guide wheels 47. The same plane can ensure the flatness between the gap baffles 48, and also ensure that the workpiece 1 is in contact with the pressing guide wheels 47, ensuring the stability during conveying and the accuracy of grinding.

[0047] The device works, the workpiece 1 is conveyed to the first edge grinding device by artificial or mechanical hand, the conveying belt motor 222 of the edge grinding conveying belt mechanism 2 drives the conveying belt driving roller 223 to rotate, and the conveying belt driven roller 224 cooperates to realize the circulation of the conveying belt 21, so that the workpiece 1 on the conveying belt 21 is conveyed to the discharge end, between the abrasive belt grinding assembly 3 and the edge grinding pressure assembly 4 of the first edge grinding assembly, the positioning motor 37 of the edge positioning unit in the abrasive belt grinding assembly 3 drives the positioning lead screw 38 to rotate, and the positioning slide block drives the edge driving unit on the positioning slide 39 to gradually approach the conveying belt 21 until it moves to the specified position, after edge positioning, the driving motor 32 of the edge driving unit drives the driving roller 33 to rotate, and the driven roller 34 cooperates to realize the circulation of the edge grinding belt paper 30, and waits for the workpiece 1 to be pressed to grind the thickness direction; when the abrasive belt grinding assembly 3 acts, the edge grinding pressure assembly 4 drives the pressing plate 44 on the pressing positioning platform 43 through the pressing cylinder 42 to resist the workpiece 1, so that the pressing guide wheel 47 on the pressing plate 44 presses the workpiece 1 to the edge grinding belt paper 30 of the abrasive belt grinding assembly 3, when the workpiece 1 contacts the edge grinding belt paper 30, continue to push the pressing plate 44, make the pressing plate 44 slide on the pressing positioning platform 43 until it is blocked on the pressing limiting part 45, so as to ensure that the workpiece 1 is pressed between the pressing guide wheel 47 and the edge grinding belt paper 30, and the workpiece 1 is ground in the thickness direction through the rotation of the edge grinding belt paper 30, the workpiece 1 is conveyed with the conveying belt 21, and the conveying is completed at the same time, which greatly improves the grinding efficiency. After grinding, the abrasive belt grinding assembly 3 and the edge grinding pressure assembly 4 move away from both sides respectively, the conveying belt 21 continues to convey the workpiece 1 to the abrasive belt grinding assembly 3 and the edge grinding pressure assembly 4 between the second edge grinding assembly, and the other side of the workpiece 1 in the thickness direction is ground through the same action, and finally the edge grinding of the workpiece 1 in the thickness direction is realized.

[0048] After the thickness direction grinding is completed, the workpiece 1 is rotated horizontally by the rotating mechanical hand, and the edge grinding of the workpiece 1 in the width direction is realized by the same edge grinding method, after the width direction grinding is completed, the workpiece 1 is rotated vertically by the rotating mechanical hand, and the edge grinding of the workpiece 1 in the length direction is realized by the same edge grinding method, finally, the workpiece 1 is sent to the abrasive belt chamfering assembly 6 and the chamfering pressure assembly 7 for inspection, the workpiece 1 is pressed on the inclined surface 601 of the chamfering abrasive belt paper 60 to realize chamfering, and four chamfering mechanisms are used to complete four times of chamfering processing, so as to realize the chamfering processing of two angles on the two sides of the workpiece 1 in the length direction.

[0049] Example two

[0050] As Figures 2 to 10As shown, in Embodiment 2, the only difference from Embodiment 1 is the order of the chamfering device. It has been moved from the last station to the second station. The length grinding and chamfering are performed first, followed by the width grinding, and finally the thickness grinding. The structure and operation of the grinding and chamfering are the same.

[0051] Example 3

[0052] like Figures 2 to 9 as well as Figure 11 As shown, compared with Example 1, Example 3 has an additional beveling device but no additional grinding device, and the order of their positions is different. Grinding and beveling are performed first along the length, followed by grinding and beveling along the width. The structure and operation of the grinding and beveling processes are the same.

[0053] This invention only illustrates three embodiments. In practical applications, different solutions can be arranged and combined according to the site conditions, which will not be elaborated here.

[0054] The advantages of this invention are that the equipment connects the edge grinding conveyor belt mechanism 2 in the edge grinding device and the edge rewinding conveyor belt mechanism 5 in the edge rewinding device, enabling the workpiece 1 to be transported on both devices, replacing manual transfer, saving transfer time, and improving conveying efficiency. The edge grinding mechanism uses the edge grinding clamping component 4 to press the workpiece 1 against the sanding belt edge grinding component 3 on the other side to achieve edge grinding; the edge rewinding mechanism uses the edge rewinding clamping component 7 to press the workpiece 1 against the sanding belt edge rewinding component 6 on the other side to achieve edge rewinding. During the processing, there is no need for manual clamping of the workpiece 1, and the grinding work can be completed during the conveying process, greatly improving the smoothness and connectivity of the entire equipment, as well as the convenience of grinding, ultimately ensuring grinding accuracy while greatly improving the overall processing efficiency.
