[0018] For the convenience of understanding the utility model, the utility model will be described more comprehensively below with reference to relevant drawings, and several embodiments of the utility model are given in the drawings, but the utility model can be realized through different forms and is not limited to the embodiments described in the text, on the contrary, these embodiments are provided to make the disclosed content of the utility model more thorough and comprehensive.

[0019] Please refer to the drawings Figures 1-3 The utility model provides a technical scheme: corrugated paper anti -folding bulge groove device, including installation frame 10, two both ends of installation frame 10 are equipped with two mobile blocks 11 that are symmetrically arranged, two mobile blocks 11 all are equipped with the sliding slot 111 that is set up, two sliding slots 111 all are equipped with groove mechanism, and groove mechanism includes the support 20 of sliding installation in sliding slot 111, and the round axle end of support 20 is fixedly connected with groove roller 21 that is rotatably installed in support 20, and second motor 22 is fixedly installed on support 20, and the output of second motor 22 penetrates support 20 and is connected with the round axle end of groove roller 21.

[0020] Specifically, groove roller 21 directly contacts the second and fourth vertical pressing lines of the carton, and when the carton is folded to 90°, groove operation is performed on the vertical pressing line position, and through the rolling of the roller, uniform indentation can be formed on the vertical pressing line, so that when the carton is subsequently folded to 180°, the inner paper can be smoothly folded along the indentation, bulge is avoided, and the forming quality of the carton is ensured. The rotation of the groove roller 21 is driven by the second motor 22, so that the rotation speed of the groove roller 21 is consistent with the conveying speed of the carton at the pre-folding part. During the groove operation, the carton folding line position can be uniformly subjected to the groove force, so that the speed mismatch does not cause poor groove effect or carton damage.

[0021] In an embodiment of the utility model, as Figure 3 shown, the mobile block 11 is composed of a horizontal block and a vertical block, the sliding slot 111 is located in the vertical block, and the extension line of the center end of the sliding slot 111 and the horizontal line of the horizontal block form a 45° angle.

[0022] When the groove mechanism moves in the sliding slot 111, the 45° angle makes the pressure direction of the groove roller 21 on the carton vertical pressing line more reasonable. The pressure can be decomposed into horizontal and vertical components, and this angle setting can make the components better act on the carton vertical pressing line, so that the groove effect is more uniform and effective, which helps to avoid the situation that the groove is not uniform or the bulge problem is not completely solved due to uneven pressure distribution. At the same time, in the pre-folding part of the automatic stapling integrated machine, the second and fourth vertical pressing lines of the carton are subjected to groove in the process of folding to 90°, and the 45° angle setting can make the movement direction of the groove mechanism match the folding direction of the carton vertical pressing line, better adapt to the folding process of the carton, so that the groove operation and the folding action of the carton are coordinated, and the accuracy and reliability of the groove are improved.

[0023] In an embodiment of the utility model, as shown in Figure 2 And Figure 3 Fixedly connected with fixed block 201 on the side of support 20 far away from pressure groove roller 21, the upper end of moving block 11 is fixedly installed with air cylinder 24, the telescopic end of air cylinder 24 penetrates moving block 11 and is communicated with sliding groove 111, transmission rod 23 is hinged between the telescopic end of air cylinder 24 and fixed block 201, pressure display table 25 is arranged on air cylinder 24, and operating personnel can accurately adjust pressure groove pressure according to different carton materials and thicknesses by observing pressure display table 25.

[0024] When the telescopic end of air cylinder 24 does telescopic motion, transmission rod 23 will be moved, since the two ends of transmission rod 23 are hinged with the telescopic end of air cylinder 24 and fixed block 201 respectively, transmission rod 23 will convert the linear motion of air cylinder 24 into the pushing force or pulling force to support 20, and makes support 20 slide in sliding groove 111.In this way, pressure groove roller 21 installed on support 20 can move along with support 20, thereby adjusting the relative position of pressure groove roller 21 and carton vertical pressing line, and ensuring that the pressure groove operation to the carton vertical pressing line at different positions can be accurately performed.

[0025] In an embodiment of the utility model, as shown in Figure 2 Two-way screw rod 12 and limiting rod 13 are rotatably installed at the both ends of the inner wall of mounting frame 10 respectively, the two ends of two-way screw rod 12 are oppositely arranged in screw thread, and the horizontal block on moving block 11 is provided with sliding hole 112 and screw hole 113, two-way screw rod 12 and limiting rod 13 penetrate screw hole 113 and sliding hole 112 respectively, two-way screw rod 12 is screw-connected with screw hole 113, and limiting rod 13 is slidingly connected with sliding hole 112, and through the limiting rod 13 arranged, the shaking and deflection of moving block 11 during movement are avoided.

[0026] In an embodiment of the utility model, as shown in Figure 1 And Figure 2 First motor 14 is fixedly installed on mounting frame 10, the output end of first motor 14 penetrates mounting frame 10, bevel gear 15 is fixedly installed on the output end of first motor 14 and two-way screw rod 12, and the two bevel gears 15 are meshed with each other.

[0027] In detail, when the first motor 14 starts, the output end drives the bevel gear 15 connected therewith to rotate, power is transmitted to the bevel gear 15 on the bidirectional screw rod 12 through the meshing transmission of the two bevel gears 15, so as to drive the bidirectional screw rod 12 to rotate, the threads at the two ends of the bidirectional screw rod 12 are oppositely arranged, and are threadedly connected with the threaded holes 113 on the moving blocks 11. When the bidirectional screw rod 12 rotates, due to the opposite directions of the threads at the two ends of the bidirectional screw rod 12, the two moving blocks 11 move towards or away from each other along the bidirectional screw rod 12, the distance between the two moving blocks 11 is adjusted, so that the position of the pressing groove mechanism mounted on the moving blocks 11 is adjusted to adapt to paper boxes of different widths, and it is ensured that the pressing groove rollers 21 can accurately press the second and fourth vertical pressing lines of the paper box.

[0028] In an embodiment of the utility model, as shown in Figure 1 and Figure 2 , the mounting frame 10 is threadedly mounted on the fixed frame at the center of the automatic nailing and folding integrated machine through the screws 16, the pressing groove roller 21 has a metal shaft core inside, the metal shaft core has high strength and rigidity, can bear the pressure generated in the pressing groove process, ensures that the pressing groove roller 21 does not deform in the rotating process, thereby ensuring the precision and stability of the pressing groove, and is wrapped with wear-resistant rubber outside, the wear-resistant rubber has good elasticity and wear resistance, in the pressing groove process, on the one hand, the pressing groove roller 21 can avoid damaging the surface of the paper box, and the appearance quality of the paper box is protected, on the other hand, the elasticity of the rubber can make the pressing groove roller 21 better adhere to the vertical pressing line of the paper box, improve the quality of the pressing groove, make the pressed groove more uniform and smooth, and effectively prevent the paper in the paper box from bulging when folding.

[0029] The utility model has been described in detail in combination with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, as long as the method concept and technical scheme of the utility model are adopted for this non-essential improvement or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
