Description

Technical Field

[0001] This invention relates to the field of cardboard box processing equipment technology, and in particular to a cardboard box quick folding and creasing device. Background Technology

[0002] Cardboard boxes are currently the most widely used packaging product in the packaging industry. Corrugated cardboard boxes, with their advantages of being lightweight, compression-resistant, recyclable, and inexpensive, are widely used in logistics transportation, product packaging, and warehousing. In the cardboard box manufacturing process, edge folding and creasing are core processes that directly determine the box's forming precision, appearance flatness, and subsequent assembly and bonding effect.

[0003] However, current cardboard box folding and creasing equipment still has the following two shortcomings in use: First, most traditional creasing equipment adopts a fixed pressure creasing operation mode, which cannot adjust the creasing force and depth in real time according to the thickness and material hardness of the cardboard. It is easy to have creasing that is too shallow or too deep. It also lacks real-time monitoring and pressure self-adjustment mechanism, making it impossible to achieve full-process quality monitoring. When defects such as creasing edges, misalignment, and uneven depth occur, it is difficult to detect them in time, which can easily produce a large number of defective products. Meanwhile, the pressure rollers of existing indentation equipment mostly adopt a rigid one-piece wheel structure, which can only complete a simple single indentation operation during the rolling indentation process. It cannot achieve the step-by-step operation of initial indentation shaping and depth shaping. The indentation lines are prone to problems such as burrs and unevenness, and the edge forming effect is poor. Summary of the Invention

[0004] This invention relates to a rapid folding and creasing device for cardboard boxes, which solves the problems of traditional creasing equipment lacking real-time monitoring and pressure self-adjustment mechanisms, making it impossible to achieve full-process quality monitoring, making it difficult to detect defects such as lace, misalignment, and uneven depth of creasing in a timely manner, and the fact that the pressure rollers mostly adopt a rigid one-piece wheel structure, which cannot achieve the step-by-step operation of initial creasing shaping and depth shaping, and the creasing lines are prone to burrs and unevenness.

[0005] This invention provides a rapid folding and creasing device for cardboard boxes, specifically comprising: a base; an electric cylinder fixedly installed at the middle of the upper end face of the base, a pressure plate fixedly installed at the end face of the telescopic part of the electric cylinder, a pressure sensor installed at the middle of the lower end face of the pressure plate, a front plate fixedly installed at the front end of the base, and a rear plate fixedly installed at the rear end face of the base; a placement plate is provided directly below the base, a connecting groove is opened on the upper end face of the placement plate, and the pressure plate is snapped into the connecting groove on the upper end face of the placement plate; a controller and an alarm are installed on the upper end face of the front plate, and the controller and the alarm are electrically connected; a vision detector is fixedly installed on the lower end face of the rear plate, and the vision detector is electrically connected to the controller; a first hanger is fixedly installed in front of the lower end face of the placement plate, a first motor is installed on the outer end face of the first hanger, a first drive shaft is drivenly connected to the front end face of the first motor, and a front pressure wheel is fixedly installed on the surface of the first drive shaft; A second hanger is fixedly installed at the rear of the lower end face of the placement plate. A second motor is fixedly installed on the outer end face of the second hanger. A second drive shaft is drivenly connected to the front end face of the second motor. A shaping wheel is fixedly installed on the surface of the second drive shaft.

[0006] Furthermore, the controller is electrically connected to the electric cylinder, and the vision detector at the lower end of the rear panel is electrically connected to the controller.

[0007] Furthermore, the main bodies of the first and second hangers are inverted U-shaped structures, the end face of the first drive shaft is rotatably connected to the side plate of the first hanger, and the end face of the second drive shaft is rotatably connected to the side plate of the second hanger.

[0008] Furthermore, the front pressure roller has arc-shaped structures at both ends, and a groove is provided in the middle of the surface of the front pressure roller.

[0009] Furthermore, rubber strips are evenly installed on the outer circumference of the shaping wheel, and the lower end faces of the shaping wheel and the front pressure wheel are on the same horizontal line.

[0010] Furthermore, threaded holes are formed on the left and right ends of the base, and a connecting plate is provided on each of the left and right ends of the base. The main body of the connecting plate is U-shaped, and through holes are formed on the vertical plates at both ends of the connecting plate. The connecting plate is connected to the base by bolts.

[0011] Furthermore, the base has four through-holes on its surface, and four limiting rods are fixedly installed on the upper surface of the placement plate. The limiting rods are slidably engaged in the limiting holes on the surface of the base.

[0012] Furthermore, the pressure sensor is electrically connected to the controller, and the lower end face of the pressure plate is in contact with the lower end face of the connecting groove.

[0013] This invention provides a rapid folding and creasing device for cardboard boxes, which has the following beneficial effects: 1. The placement plate is equipped with a front pressure roller and a shaping roller. The front pressure roller will initially roll and squeeze the carton. The outer end face of the front pressure roller has a groove in the middle, which can make the crease lines more regular and avoid burrs. The shaping roller can deepen and correct the crease. At the same time, the rubber strips evenly installed on the outer circumference of the shaping roller can increase the contact friction with the carton board and buffer the squeezing force to ensure the crease shaping effect. The front pressure roller and the shaping roller work together to improve the crease quality.

[0014] 2. A rear plate is installed at the rear of the upper end of the base. A vision detector is installed on the lower end of the rear plate. The vision detector can monitor the indentation in real time. If the indentation is found to be too shallow or too deep, the vision detector can send an abnormal signal to the controller. After analysis and processing, the controller will send a command to the electric cylinder, so that the extension and retraction part of the electric cylinder can drive the pressure plate to move up or down, thereby ensuring that the depth of the indentation is within the set range.

[0015] 3. The pressure plate at the end of the electric cylinder telescopic part is engaged in the connecting groove on the upper surface of the placement plate, so that when the electric cylinder telescopic part drives the pressure plate to move up and down, the placement plate will also move up and down. Two sets of limit rods are fixedly installed on the upper surface of the placement plate, and limit holes are opened on the surface of the base. The limit rods are slidably connected in the limit holes, so that the placement plate will not wobble left and right when it moves up and down, ensuring the linear movement of the placement plate and ensuring that the pressure sensor can accurately measure the pressure of the pressure plate on the placement plate.

[0016] 4. A front plate is fixedly installed at the upper front of the base, and an alarm is fixedly installed on the upper surface of the front plate. When the visual detector detects that the indentation has a rough edge or cracks, the controller can make the alarm sound to remind the worker that there is a quality problem with the indentation operation, so that the worker can check and maintain it in time to ensure the quality of the indentation operation.

[0021] Example 1: Please refer to Figures 1 to 8 : This invention proposes a rapid folding and creasing device for cardboard boxes, comprising: a base 1; an electric cylinder 2 is fixedly installed at the middle position of the upper end face of the base 1, a pressure plate 201 is fixedly installed at the end face of the telescopic part of the electric cylinder 2, a pressure sensor 2011 is installed at the middle position of the lower end face of the pressure plate 201, a front plate 4 is fixedly installed at the front end of the base 1, a rear plate 5 is fixedly installed at the rear end face of the base 1, and a placement plate 3 is provided directly below the base 1. A connecting groove 301 is opened on the upper end face of the placement plate 3, and the pressure plate 201 is engaged in the connecting groove 301 on the upper end face of the placement plate 3, so that the placement plate 3 can move up and down after the electric cylinder 2 is started; A controller 401 and an alarm 402 are installed on the upper surface of the front plate 4. The controller 401 and the alarm 402 are electrically connected. The front plate 4 is fixedly installed in front of the upper surface of the base 1. The alarm 402 is fixedly installed on the upper surface of the front plate 4. When the visual detector 501 detects that the indentation has a rough edge or cracks, the controller 401 can make the alarm 402 sound an alarm to remind the worker that there is a quality problem in the indentation operation, so that the worker can inspect and maintain it in time to ensure the quality of the indentation operation. A vision detector 501 is fixedly installed on the lower end face of the rear plate 5, and the vision detector 501 is electrically connected to the controller 401; a first hanger 303 is fixedly installed in front of the lower end face of the placement plate 3, a first motor 7 is installed on the outer end face of the first hanger 303, a first drive shaft 701 is connected to the front end face of the first motor 7, and a front pressure wheel 8 is fixedly installed on the surface of the first drive shaft 701. A second hanger 304 is fixedly installed at the rear of the lower end face of the placement plate 3. A second motor 9 is fixedly installed on the outer end face of the second hanger 304. A second drive shaft 901 is connected to the front end face of the second motor 9. A shaping wheel 10 is fixedly installed on the surface of the second drive shaft 901.

The end face of the first drive shaft 701 is rotatably connected to the side plate of the first hanger 303, and the end face of the second drive shaft 901 is rotatably connected to the side plate of the second hanger 304.

[0022] The controller 401 is electrically connected to the electric cylinder 2. The vision detector 501 at the lower end of the rear plate 5 is electrically connected to the controller 401. The pressure sensor 2011 is electrically connected to the controller 401. The lower end face of the pressure plate 201 is in contact with the lower end face of the connecting groove 301. During use, the pressure sensor 2011 is electrically connected to the controller 401. The pressure sensor 2011 can transmit the monitored pressure value to the controller 401. The rear plate 5 is installed at the rear of the upper end face of the base 1. The vision detector 501 is installed at the lower end face of the rear plate 5. The vision detector 501 can monitor the indentation in real time. If the indentation is found to be too shallow or too deep, the vision detector 501 can send an abnormal signal to the controller 401. After analysis and processing, the controller 401 will send a command to the electric cylinder 2, so that the extension part of the electric cylinder 2 can drive the pressure plate 201 to move upward or downward, thereby ensuring that the depth of the indentation is within the set range.

[0023] The base 1 has threaded holes on its left and right ends, and a connecting plate 6 is provided on each of its left and right ends. The main body of the connecting plate 6 is U-shaped, and through holes are provided on the vertical plates at both ends of the connecting plate 6. The connecting plate 6 is connected to the base 1 by bolts. In use, the base 1 has two threaded holes on each of its left and right ends, and the connecting plate 6 has two through holes on its vertical plates. Workers can use bolts to fix the connecting plate 6 to the outside of the base 1, and the outer end of the connecting plate 6 can be connected to other components to fix the base 1.

[0024] The base 1 has four through-holes 101 on its surface. The upper end of the placement plate 3 is fixedly installed with four limiting rods 302. The limiting rods 302 are slidably engaged in the limiting holes 101 on the surface of the base 1. During use, the limiting holes 101 on the surface of the base 1 and the limiting rods 302 are slidably connected in the limiting holes 101, so that the placement plate 3 will not wobble left or right when it moves up and down, ensuring the linear up and down movement of the placement plate 3 and ensuring that the pressure sensor 2011 can accurately measure the pressure of the pressure plate 201 on the placement plate 3.

[0025] Example 2, based on Example 1, such as Figures 1-8 As shown, the front pressure roller 8 has arc-shaped structures at both ends, and a groove 801 is provided in the middle of the surface of the front pressure roller 8. Rubber strips 1001 are evenly installed on the outer circumference of the shaping roller 10. The lower end face of the shaping roller 10 and the front pressure roller 8 are on the same horizontal line.

[0026] The technical effects achieved by adopting the above solution are as follows: A first hanger 303 and a second hanger 304 are fixedly installed on the lower end face of the placement plate 3. A first motor 7 is installed on the outer end face of the first hanger 303, and a second motor 9 is fixedly installed on the outer end face of the second hanger 304. A front pressure roller 8 is fixedly installed on the surface of the first drive shaft 701 at the front end of the first motor 7, and a shaping roller 10 is fixedly installed on the surface of the second drive shaft 901 at the front end of the second motor 9. After the first motor 7 is started, the front pressure roller 8 will initially roll and squeeze the carton. A groove 801 is provided in the middle of the outer end face of the wheel 8, which can make the folding and crease lines more regular and avoid burrs. When the second motor 9 drives the shaping wheel 10 on the surface of the second drive shaft 901 to rotate, the shaping wheel 10 can deepen and correct the crease. At the same time, the rubber strips 1001 evenly installed on the outer circumference of the shaping wheel 10 can increase the contact friction with the carton board and buffer the squeezing force. This can not only ensure the folding and shaping effect, but also prevent the hard wheel from scratching the surface of the carton and improve the quality of the finished product.

[0027] The working principle of this embodiment: In this invention, two threaded holes are respectively opened at the left and right ends of the base 1, and two through-holes are opened on the vertical plate surface of the connecting plate 6. Workers can use bolts to fix the connecting plate 6 to the outside of the base 1, and one side of the connecting plate 6 can be connected to other components to fix the base 1. The pressure plate 201 at the end of the telescopic part of the electric cylinder 2 is engaged in the connecting groove 301 on the upper surface of the placement plate 3, so that when the telescopic part of the electric cylinder 2 drives the pressure plate 201 to move up and down, the placement plate 3 will also move up and down. Two sets of limiting rods 302 are fixedly installed on the upper surface of the placement plate 3. A limiting hole 101 is provided on the surface of the base 1, and a limiting rod 302 is slidably connected in the limiting hole 101, so that the placement plate 3 will not wobble left or right when moving up and down, ensuring the linear movement of the placement plate 3 and ensuring that the pressure sensor 2011 can accurately measure the pressure of the pressure plate 201 on the placement plate 3. When creasing the carton, the extension part of the drive electric cylinder 2 drives the pressure plate 201 to press down vertically. The front pressure roller 8 and the shaping roller 10 at the lower end of the placement plate 3 squeeze the carton in turn, thereby improving the work quality. The middle position of the lower end face of the pressure plate 201 is fixedly installed. Equipped with a pressure sensor 2011, when the pressure plate 201 presses against the placement plate 3, the pressure sensor 2011 can monitor the pressure value. The pressure sensor 2011 is electrically connected to the controller 401, and can transmit the monitored pressure value to the controller 401. A rear plate 5 is installed behind the upper end face of the base 1, and a vision detector 501 is installed on the lower end face of the rear plate 5. The vision detector 501 can monitor the indentation in real time. If the indentation is found to be too shallow or too deep, the vision detector 501 can send an abnormal signal to the controller 401. 01. After analysis and processing, the controller 401 sends a command to the electric cylinder 2, causing the extension and retraction part of the electric cylinder 2 to move the pressure plate 201 up or down, thereby ensuring that the depth of the indentation is within the set range. A front plate 4 is fixedly installed in front of the upper end of the base 1, and an alarm 402 is fixedly installed on the upper end of the front plate 4. When the visual detector 501 detects that the indentation has a frayed edge or a crack, the controller 401 can make the alarm 402 sound an alarm to remind the worker that there is a quality problem in the indentation operation, so that the worker can check and maintain it in time to ensure the quality of the indentation operation.
