Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing equipment technology, and in particular to a folding machine for cardboard box processing. Background Art

[0002] In the cardboard box manufacturing industry, creases are an indispensable and important part of the cardboard box forming process. Traditional cardboard box crease processes mainly rely on manual operation, with workers using simple tools such as rulers and knives to manually crease the cardboard.

[0003] This method has many drawbacks. First, manual operation is extremely inefficient. In large-scale cardboard box production, it requires a large amount of manpower and a long time, severely restricting production speed and failing to meet the demands of the modern packaging industry for high-efficiency production. Second, the precision of manual folding is difficult to guarantee. Due to differences in the operating techniques and force applied by different workers, the depth, width, and straightness of the folds vary. This not only affects the appearance quality of the cardboard box but also causes deviations in subsequent folding and forming processes, reducing the product's pass rate. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional cardboard box creases rely mainly on manual creasing using simple tools. This method suffers from low efficiency, severely restricting production speed in large-scale cardboard box production and failing to meet the demands of the modern packaging industry for high-efficiency production. Furthermore, the precision of manual creases is difficult to guarantee; due to differences in the operating techniques and force applied by different workers, the depth, width, and straightness of the creases vary, affecting not only the appearance quality of the cardboard box but also causing deviations in subsequent folding and forming processes, thus reducing the product's pass rate. Therefore, this invention provides a crease machine for cardboard box processing.

[0005] This utility model achieves the above objectives through the following technical solutions:

A centering component is provided on both sides of the first conveying device on the upper surface of the work platform, a pressure roller assembly is provided between the first conveying device and the second conveying device, and a folding component is provided in the middle of the upper surface of the work platform.

[0007] Furthermore, the working platform is provided with a first groove and a second groove at both ends, the first conveying device is installed in the first groove, the second conveying device is installed in the second groove, the working platform is provided with rectangular holes on both sides of the first groove, and two sets of fixing plates are provided on the upper surface of the working platform for installing the pressure roller assembly.

[0008] Furthermore, the centering component includes a first mounting plate, on the upper surface of which a first cylinder is provided. The first cylinder is a bidirectional cylinder, and clamping elements are provided at both output ends of the first cylinder. A rectangular frame is provided at the lower end of the clamping element, and several rollers are rotatably connected within the rectangular frame.

[0009] Furthermore, the pressure roller assembly includes a rotating roller rotatably connected between the fixed plates. One end of the rotating roller passes through the fixed plate and is provided with a first transmission wheel. A first motor is provided on the upper surface of one of the fixed plates, and a second transmission wheel is provided at the output end of the first motor. The second transmission wheel is connected to one of the first transmission wheels by a transmission belt, and the two sets of first transmission wheels are connected by a transmission belt.

With the coordinated operation of the pressing component and the crease component, there is no need for frequent manual handling of cardboard, reducing manpower input, meeting the high-efficiency requirements of large-scale carton production, and solving the problem of low efficiency of traditional manual operation.

[0013] 2. The bidirectional first cylinder and the clamping parts at both ends of the centering component can accurately adjust the position of the cardboard. Through the rollers in the rectangular frame, the cardboard can be quickly centered to the ideal position without damaging it, ensuring the accuracy of subsequent creases and avoiding crease errors caused by cardboard position deviations, thus effectively improving the product qualification rate.

[0014] 3. The bidirectional lead screw of the crease assembly works in conjunction with the moving plate to flexibly adjust the position of the pressure roller according to the size of the cardboard. The second cylinder drives the horseshoe plate and pressure roller to press down, which can ensure that the depth, width and straightness of the crease are uniform and consistent. This overcomes the quality problems caused by differences in operation techniques and force in manual creases, and improves the appearance quality and forming effect of the carton.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Combination Figures 1 to 5 The folding machine shown for cardboard box processing includes a work platform 10. A first conveying device 20 and a second conveying device 30 are respectively provided at both ends of the work platform 10. It is equipped with a high-precision motor-driven transmission belt, which can realize the fast and stable conveying of cardboard, greatly improving production efficiency. Centering components 40 are provided on both sides of the first conveying device 20 on the upper surface of the work platform 10 to ensure the subsequent folding accuracy. A pressure roller assembly 50 is provided between the first conveying device 20 and the second conveying device 30 to ensure that the cardboard is flat when folding. A folding component 60 is provided in the middle of the upper surface of the work platform 10.

[0024] The working platform 10 has a first groove 101 and a second groove 102 at both ends. The first conveying device 20 is installed in the first groove 101 and the second conveying device 30 is installed in the second groove 102. The working platform 10 has rectangular holes 103 on both sides of the first groove 101. The upper surface of the working platform 10 has two sets of fixing plates 104 for installing the pressure roller assembly 50.

[0025] The centering assembly 40 includes a first mounting plate 401, which is tightly connected to the working platform 10 by bolts to ensure the stability of the entire centering assembly. A first cylinder 402 is provided on the upper surface of the first mounting plate 401. The first cylinder 402 is a bidirectional cylinder, and clamping parts 403 are provided at both output ends of the first cylinder 402. A rectangular frame 404 is provided at the lower end of the clamping parts 403. Several rollers 405 are rotatably connected inside the rectangular frame 404. When the cardboard is conveyed to the centering assembly position, the first cylinder 402 works, pushing the clamping parts 403 to move in opposite directions. The rollers 405 inside the rectangular frame 404 at the lower end of the clamping parts 403 contact the edge of the cardboard. The rollers 405 can rotate flexibly with the movement of the cardboard, which not only ensures the stable clamping of the cardboard, but also prevents scratches on the surface of the cardboard. This structural design can quickly and accurately center the cardboard to the predetermined position, ensuring the accurate position of the cardboard in the subsequent pressing and crease processes, improving the benchmark and quality of the creases, and reducing the scrap rate.

[0026] The pressure roller assembly 50 includes a rotating roller 501 rotatably connected between fixed plates 104. One end of the rotating roller 501 passes through the fixed plate 104 and is provided with a first transmission wheel 502. A first motor 503 is provided on the upper surface of one of the fixed plates 104, and a second transmission wheel 504 is provided at the output end of the first motor 503. The second transmission wheel 504 is connected to one of the first transmission wheels 502 by a transmission belt. The two sets of first transmission wheels 502 are connected by a transmission belt to ensure that the two rotating rollers 501 can rotate synchronously. When the cardboard passes through the rotating roller 501, the rotating roller 501 applies uniform pressure to the cardboard, making the cardboard flat and eliminating any possible wrinkles and unevenness. This lays a good foundation for the precise creases of the subsequent crease assembly 60, and improves the quality and effect of the creases.

[0027] The crease assembly 60 includes a second mounting plate 601, which is tightly connected to the work platform 10 by bolts. Both ends of the upper surface of the second mounting plate 601 are provided with baffles 602, and a lead screw 603 is rotatably connected between the two sets of baffles 602. The lead screw 603 is a bidirectional lead screw. A second motor 604 is provided on the outer side of one of the baffles 602, and the second motor 604 is connected to the lead screw 603. Moving plates 605 are respectively provided on the left and right sections of the lead screw 603. The 05 and the lead screw 603 are connected by a ball nut for transmission. The moving plate 605 is equipped with a second cylinder 606. The output end of the second cylinder 606 is equipped with a horseshoe plate 607. The pressure roller 608 is rotatably connected between the horseshoe plates 607. The second motor 604 drives the lead screw 603 to rotate. Since the lead screw 603 is a bidirectional lead screw, when it rotates, the left and right moving plates 605 can move synchronously in opposite directions, which makes it convenient to flexibly adjust the position of the pressure roller 608 according to the size of different cardboard.
