[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] As shown in Figure 1 - Figure 4 The utility model provides a kind of technical scheme: box door seal strip production is with deburring mechanism, mounting bracket 1 and the edge cutting component 11 being set in the bottom of mounting bracket 1;

[0027] Drive assembly 2, drive assembly 2 is placed in the inner cavity of mounting bracket 1, and drive assembly 2 includes the limiting column 21 being rotatably connected in the bottom of the inner cavity of mounting bracket 1, the inner cavity of limiting column 21 is provided with support rod 26, the top of limiting column 21 is fixedly connected with first support plate 22, the bottom of first support plate 22 is rotatably connected with connecting rod 23, the top of connecting rod 23 is rotatably connected with first sliding rod 27, and the side of first sliding rod 27 is provided with second support plate 28;

[0028] The positioning assembly 3 is arranged on the top of the second supporting plate 28, the positioning assembly 3 comprises a fixed plate 31 fixedly connected to the top of the first sliding rod 27, the side of the fixed plate 31 away from the first sliding rod 27 is provided with a placing seat 32, the outer surface of the limiting column 21 is provided with a limiting groove 24, the inner cavity of the limiting groove 24 is slidably connected with a fixed block 25, the side of the fixed block 25 is fixedly connected with a supporting rod 26, one end of the supporting rod 26 away from the fixed block 25 is fixedly connected to the side of the trimming member 11, the top of the second supporting plate 28 is provided with a second sliding groove 211, the inner cavity of the second sliding groove 211 is slidably connected with a second sliding rod 210, the top of the second sliding rod 210 is fixedly connected with the bottom of the fixed plate 31, the bottom of the second supporting plate 28 is provided with a first sliding groove 29, one end of the first sliding rod 27 extends into the inner cavity of the first sliding groove 29, and one end of the first sliding rod 27 is slidably connected with the inner cavity of the first sliding groove 29. By arranging the mounting frame 1, the trimming member 11 can be supported. In use, first, the sealing strip to be deburred is placed on the top of the placing seat 32, and then the trimming member 11 is started, so that the trimming member 11 can move downward, and then the fixed block 25 can be driven to move downward through the supporting rod 26. When the fixed block 25 moves downward, the limiting groove 24 and the fixed block 25 cooperate, so that the limiting column 21 can move counterclockwise, and then the first supporting plate 22 can drive the connecting rod 23 to move counterclockwise. When the connecting rod 23 moves, the first sliding rod 27 can move along the inner cavity of the first sliding groove 29 to the middle of the placing seat 32, and then the fixed plate 31 can be driven to move. When the fixed plate 31 moves to a certain position, the inner wall of the fixed plate 31 is in contact with the side of the sealing strip, so that the position of the sealing strip can be positioned. At this time, the trimming member 11 continues to move downward, so that the outer edge of the sealing strip can be deburred, avoiding the deformation of the sealing strip when the trimming member 11 cuts off, causing damage. The working efficiency is effectively improved. When the fixed plate 31 moves, the second sliding rod 210 and the second sliding groove 211 cooperate, so that the movement track of the fixed plate 31 can be limited.

[0029] Further, as shown in Figure 3 and Figure 4 , the side of the fixed plate 31 is provided with a groove 33, the side of the fixed plate 31 is fixedly connected with an elastic sheet 34, one end of the elastic sheet 34 away from the fixed plate 31 is fixedly connected with a flexible clamping plate 35. By arranging the flexible clamping plate 35, the sealing strip can be pushed to move. By arranging the groove 33, the burr of the sealing strip can be cut off. When the trimming member 11 cuts off the burr, the elastic sheet 34 and the flexible clamping plate 35 cooperate, so that the stress area of the sealing strip can be adjusted, and the uniformity of stress distribution when cutting off the burr is effectively improved.

[0030] In the process of moving the fixed plate 31, due to the bottom of the sealing strip directly contacting the placing seat 32, friction is inevitably generated in the process of moving the sealing strip, and stress opposite to the moving direction of the fixed plate 31 is formed, as shown in Figure 4 In the present scheme, the bottom of the placing seat 32 is rotationally connected with the telescopic rod 36, one end of the telescopic rod 36 away from the placing seat 32 is rotationally connected to the bottom of the fixed plate 31, when the fixed plate 31 moves to the middle part of the placing seat 32, the telescopic rod 36 shrinks, thereby compensating the moving distance of the fixed plate 31, effectively improving the stability of the fixed plate 31 and reducing the positional error of the fixed plate 31 in the moving process.

[0031] As shown in Figures 1-4

[0032] In use: first, place the sealing strip to be deburred on the top of the placing seat 32, then start the edge cutting member 11, so as to drive the edge cutting member 11 to move downward, thereby achieving the effect of driving the fixed block 25 to move downward through the supporting rod 26, when the fixed block 25 moves downward, the limiting column 21 is driven to move counterclockwise through the cooperation of the limiting slot 24 and the fixed block 25, thereby achieving the effect of driving the connecting rod 23 to move counterclockwise through the first supporting plate 22, when the connecting rod 23 moves, the first sliding rod 27 is driven to move along the inner cavity of the first sliding slot 29 to the middle part of the placing seat 32, thereby achieving the effect of driving the fixed plate 31 to move, by setting the flexible clamping plate 35, the sealing strip is driven to move, by setting the groove 33, the edge of the sealing strip is cut off, when the edge cutting member 11 cuts off the edge, the stress area of the sealing strip is adjusted through the cooperation of the elastic sheet 34 and the flexible clamping plate 35, thereby effectively improving the uniformity of stress distribution when cutting off the edge, at this time, the edge cutting member 11 continues to move downward, thereby deburring the outer edge of the sealing strip.

[0033] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms, any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the present application.​
