[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] A multimedia information box forming production line, the production line includes a conveyor belt 4 for discharging the main body of the information box. One end of the conveyor belt 4 is provided with a slitter 1. The slitter 1 cuts the formed main body of the information box. After the information box is conveyed and leveled from the raw material coil, it is input to a punching machine, and holes are punched in the material in sequence by the punching machine. These holes are used for the incoming and outgoing lines of the information box. After the punching operation, the material is sent to a bending device to be bent into a U-shaped main body of the information box, and then enters the slitter 1 for processing.

[0041] As Figures 1 - 5 shown, a mounting plate 11 is fixedly provided on the slitter 1. The mounting plate 11 is vertically fixed on the slitter 1. An installation groove 13 is formed on one side of the slitter 1, and a guide table 5 is fixedly provided on the other side. The guide table 5 feeds the U-shaped main body of the information box into the slitter 1 and passes through a U-shaped groove 20 provided on the slitter 1 to above the conveyor belt 4. The installation groove 13 is inclined, and guide plates 12 are fixedly provided on both sides of the installation groove 13. A limiting block 31 is slidably installed between the two guide plates 12. The front side of the limiting block 31 faces the conveyor belt 4, and the rear side faces the installation groove 13. A cutter 2 is provided between the installation groove 13 and the limiting block 31.

[0042] A through groove 14 is fixedly provided in the installation groove 13 on the mounting plate 11. Both the through groove 14 and the U-shaped groove 20 penetrate the mounting plate 11. Guide wheels 130 are rotatably provided on both sides of the installation groove 13. The guide wheels 130 are attached to the front side of the cutter 2. The cutter 2 moves along the installation groove 13. Both sides of the cutter 2 are attached to the inner wall of the installation groove 13. The guide wheels 130 guide the movement of the cutter 2 so that the cutter 2 will not deviate in the horizontal direction.

[0043] A main cylinder 15 is fixedly installed on the slitter 1. The output end of the main cylinder 15 is fixedly installed with a connecting plate 16. A supporting claw 17 is fixedly provided on one side of the connecting plate 16. A pressing claw 18 is fixedly provided on the connecting plate 16. The pressing claw 18 and the supporting claw 17 are arranged alternately. The connecting plate 16 is fixedly connected to the cutter 2. The connection methods include welding fixation, connection by bolts, rivets, etc. A cylinder 10 is fixedly installed on the rear side of the mounting plate 11. The output end of the cylinder 10 is fixedly connected to a V-shaped block 101.

[0044] The output direction of the cylinder 10 is parallel to the through groove 14. The V-shaped block 101 is pushed obliquely upward by the output end of the cylinder 10.

[0045] As Figure 9 、 Figure 10As shown in the figure, a side roller 19 is rotatably arranged inside the guide plate 12. The side roller 19 is attached to the side wall of the limit block 31 to limit the movement of the limit block 31. By using the side roller 19, it is ensured that the moving direction of the limit block 31 is the same as that of the cutting knife 2. A mounting block 3 is fixedly connected to the top of the limit block 31. The U-shaped groove 20 penetrates through the cutting knife 2 and the mounting block 3. A sliding rod is fixedly connected to the top of the mounting block 3, and the sliding rod is slidably connected to the top of the slitter 1. A fitting groove 36 is formed on one side of the mounting block 3, and the fitting groove 36 is arranged on the upper and lower sides of the mounting block 3.

[0046] The fitting groove 36 located on the upper side is arranged in alignment with the pressing claw 18. The pressing claw 18 moves downward to be connected to the fitting groove 36, pressing down on the mounting block 3, so that the mounting block 3 and the limit block 31 move together with the cutting knife 2. If the fitting groove 36 located on the lower side is arranged in alignment with the supporting claw 17, the supporting claw 17 is clamped with the fitting groove 36 to keep the positions of the cutting knife 2 and the mounting block 3 stable. At this time, the U-shaped grooves 20 on both of them are aligned, facilitating the subsequent information box body to pass through the U-shaped grooves 20 on both of them to reach the corresponding length for cutting.

[0047] A support block 32 is fixedly arranged at the bottom of the limit block 31. One side of the support block 32 is fixedly connected to the limit block 31, and a cross bar 34 is fixedly arranged on the other side. The cross bar 34 passes through the through groove 14 and is located on the V-shaped block 101. When the device is not working, at this time, the output end of the first cylinder 10 extends to lift the limit block 31 by the cross bar 34 to ensure the structural stability of the limit block 31 when it is not working.

[0048] A groove 33 is formed on the support block 32, and the groove 33 is arranged corresponding to the cutting knife 2. When the cutting knife 2 works and moves downward into the groove 33, at this time, the cutting of the information box body has been completed, and the pressing claw 18 is connected to the fitting groove 36 on the mounting block 3. Continuing to move the cutting knife 2 downward, a driving force is applied to the entire limit block 31 by the pressing claw 18 and the cutting knife 2, so that the limit block 31 moves together with the cutting knife 2 until the main cylinder 15 moves the cutting knife 2 and the limit block 31, and the information box body cut from the limit block 31 is placed on the conveyor belt 4 to send out the information box.

[0049] A first spring 35 is fixedly arranged at the lower end of the limit block 31, and the first spring 35 is fixedly connected to the mounting groove 13 to support the limit block 31 and facilitate the reset movement of the limit block 31.

[0050] As Figures 6 - 8 shown, a fixed block 7 is fixedly arranged at the rear side of the mounting plate 11 and above the guiding table 5. A second cylinder 71 is tightly mounted on the fixed block 7. The output end of the second cylinder 71 is fixedly connected to a pushing block 73. Oblique sliding surfaces 74 are formed on both sides of the pushing block 73. A fixed rod 72 is fixedly arranged on one side of the fixed block 7.

[0051] On one side of the pushing block 73, a third cylinder 78 is fixedly installed. The output end of the third cylinder 78 is fixedly connected with a pressing shaft 781. Below the pushing block 73, a cross plate 75 is fixedly connected. On the cross plate 75 and located at the position of the pushing block 73, a slide rail 76 is fixedly installed. On the slide rail 76, a second spring 77 is installed. On the slide rail 76, a mounting bracket 79 is slidably connected. The second spring 77 is fixedly connected between the mounting bracket 79 and the pushing block 73. At the bottom of the pushing block 73, a pressure roller 751 is rotatably installed. The pressure roller 751 positions the information box body in a limited way, so that it slides on the feeding table 5.

[0052] On the mounting bracket 79, a support roller 791 is rotatably installed. The support roller 791 is located inside the U-shaped information box body. In order to support the U-shaped structure of the information box body and reduce the friction between the information box body and the U-shaped groove 20 on the mounting plate 11, on one side of the mounting bracket 79, a support rod 70 is fixedly connected. On the support rod 70, an inclined block 701 is fixedly installed. The support rods 70 on the two mounting brackets 79 are arranged staggeredly, and the inclined surfaces of the two inclined blocks 701 are arranged crosswise.

[0053] The pressing shaft 781 is located above the two inclined blocks 701 and is slidably connected with the two inclined blocks 701 at the same time. When the pressing shaft 781 moves downward, the two inclined blocks 701 move in opposite directions, so that the distance between the two mounting brackets 79 is reduced. On the contrary, when the pressing shaft 781 moves upward, then the two mounting brackets 79 are pushed by the elastic force of the second spring 77, and the distance between the two mounting brackets 79 becomes larger.

[0054] The above adjustment of the distance between the mounting brackets 79 is to change the distance between the support rollers 791 on both sides. For the information box body with a relatively thick plate, such as a wall thickness of 1 - 1.5 mm, it is necessary to reduce the support distance of the support rollers 791. For the information box body with a relatively thin plate, such as a wall thickness of 0.6 - 0.8 mm, it is necessary to increase the distance of the support rollers 791 to support the U-shaped information box body.

[0055] As Figure 11 、 Figure 12 shown, at the rear side of the mounting plate 11 and on both sides of the feeding table 5, bases 6 are fixedly installed. On the side of the base 6 facing the feeding table 5, a telescopic tube 61 is fixedly installed. One end of the telescopic tube 61 is fixedly connected to the base 6, and the other end is fixedly connected to a side plate 62. On both sides of the side plate 62, adjustment rollers 63 are rotatably installed. When the telescopic tube 61 extends or contracts, the horizontal position of the adjustment rollers 63 can be improved, so that the adjustment rollers 63 on both sides of the information box body move horizontally to adjust the distance between the adjustment rollers 63 and the information box body.

[0056] Two columns 67 are fixedly arranged on the side plate 62. A third spring 68 is fixedly arranged at the top of the column 67. A moving frame 69 is slidably arranged on the column 67. The top of the moving frame 69 is fixedly connected to the third spring 68. A push rod 690 is rotatably arranged between the two moving frames 69. A roller 691 is rotatably installed below the moving frame 69. The roller 691 is located on the top of the information box body to limit and guide the information box body.

[0057] On the side of the side plate 62 away from the roller 691, a supporting and fixing plate 623 is fixedly arranged. A top rod 692 is rotatably arranged on the supporting and fixing plate 623. One end of the top rod 692 away from the supporting and fixing plate 623 is rotatably connected to the top rod 692. A sliding groove 693 is formed on the top rod 692. A sliding block 695 is slidably arranged in the sliding groove 693. One end of the sliding block 695 is rotatably provided with a moving block 694. A motor 621 is fixedly arranged on one side of the side plate 62. The housing of the motor 621 is installed between the side plate 62 and the top rod 692 through bolts. And the output end of the motor 621 is fixedly installed with a lead screw 622. The lead screw 622 penetrates through and is threadedly connected to the moving block 694.

[0058] The motor 621 drives the lead screw 622 to rotate. The lead screw 622 controls the movement of the moving block 694 on the lead screw 622 through a threaded driving method. Its moving direction is controlled by the forward and reverse rotation of the lead screw 622. If the moving block 694 moves towards the side plate 62, the top rod 692 is pulled to rotate through the sliding block 695. During this process, the sliding block 695 slides in the sliding groove 693. The top rod 692 rotates clockwise, which will control the push rod 690 to move upward, and then control the adjustment to raise the height of the moving frame 69 and the roller 691. On the contrary, the height of the roller 691 will be reduced.

[0059] A driven rod 64 is fixedly arranged on the top of the side plate 62. A horizontal groove 65 is horizontally arranged in the driven rod 64. A fourth spring 66 is fixedly arranged at one end of the horizontal groove 65 away from the side plate 62. The driven rods 64 on the two bases 6 are symmetrically arranged on one side of the fixed block 7. The fixed rod 72 is slidably connected to the horizontal groove 65. One end of the fourth spring 66 abuts against the fixed rod 72. The inclined sliding surface 74 is located below the driven rod 64.

[0060] When the push block 73 moves upward under the driving action of the second cylinder 71, it moves upward through the inclined sliding surface 74. The inclined sliding surface 74 is slidably connected to the end of the driven rod 64. As the inclined sliding surface 74 moves upward, the driven rod 64 gradually moves away from the push block 73 to control the positions of the two side plates 62 away from the information box. On the contrary, when the push block 73 moves downward, the elastic force of the fourth spring 66 is released, and the two side plates 62 approach the information box.

[0061] The working process is as follows:

[0062] During the processing, the information box is initially formed through production and processing to obtain the box body structure of the main body, and then it is sent to the material guiding table 5. It is input into the U-shaped groove 20 of the mounting plate 11 from the material guiding table 5, and then passes through the U-shaped groove 20 of the cutting knife 2 and the limiting block 31. When the length extending into the limiting block 31 reaches the required specified length, the connecting plate 16 is controlled by the main cylinder 15 to move obliquely downward. The wall of the U-shaped groove 20 on the cutting knife 2 is the cutting edge. When the cutting knife 2 moves obliquely downward, it will contact at least two surfaces of the main body plate of the information box, increasing the shearing force on the plate. Using this method of cutting can improve the cutting effect and avoid problems such as plate depression and bending caused by cutting the plate vertically.

[0063] After cutting the plate, the cutting knife 2 presses down on the limiting block 31, and the clamping claw 18 is connected to the mating groove 36 on the mounting block 3, driving the limiting block 31 to move downward. The cut main body of the information box is placed on the conveyor belt 4, and the conveyor belt 4 operates to convey the main body of the information box for discharging. Then, the cutting knife 2 and the limiting block 31 on the device are reset. The main body of the information box produced by cutting and riveting with the produced end plate can obtain the required high-strength multimedia information box. This device quickly cuts the main body of the information box. The produced main body of the information box is an integral structure with high strength, and there is no need for assembly operations of redundant plates.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
