Description

Technical Field

[0001] This invention relates to the field of carton pressing machine technology, and more particularly to an automatic carton pressing machine. Background Technology

[0002] The top-and-bottom box is a classic packaging format, widely used for packaging various high-end products due to its elegant appearance and practical function. The top lid symbolizes "heaven," and the bottom box body symbolizes "earth," together forming a complete packaging box. This design is not only aesthetically pleasing but also provides excellent protection, making it suitable for the outer packaging of various goods such as gifts, cosmetics, and electronic products.

[0003] Pressing the box is an indispensable step in the production of top and bottom lid packaging boxes, and its main purposes include:

[0004] 1. Enhanced structural strength: Pressing the box tightly binds all components of the lid and top lid gift box together, improving the overall strength of the gift box and preventing deformation during transportation or handling.

[0005] 2. Improved appearance quality: After the box is pressed, the surface of the gift box is smoother and the lines are clearer and sharper, presenting a better visual effect and giving people a refined and high-end feeling.

[0006] 3. Ensure dimensional accuracy: By applying appropriate pressure to the gift box, its final size can be better controlled, ensuring that each finished product meets the design requirements and achieving the goal of standardized production.

[0007] Currently, the common practice is to use a box-pressing machine to press the lid and body of the box. Existing box-pressing machines typically consist of a belt conveyor, a cylinder, and a pressing plate. The workflow is as follows: First, the lid and body of the box are manually assembled. Then, the assembled box is placed on the belt conveyor, which transports it to the pressing plate. Subsequently, the cylinder drives the pressing plate to lift and lower, pressing the box. Finally, the pressed box is transported by the belt conveyor to the next process.

[0008] However, manually assembling the lid and body of the top and bottom lid packaging box one by one has the following drawbacks:

[0009] 1. High labor intensity: Workers need to spend a lot of time and energy to complete each product, which increases labor costs.

[0010] 2. Low efficiency: Manual assembly greatly reduces the speed of the production line, especially when facing large-volume orders, becoming a bottleneck in production. Summary of the Invention

[0011] The purpose of this invention is to provide an automatic box pressing machine capable of automatically assembling box lids and boxes in order to solve the above-mentioned problems.

[0012] To achieve the above objectives, the present invention adopts the following technical solution: an automatic box pressing machine, comprising a belt conveyor, a gantry frame connected to the right side of the belt conveyor body, a pressing mechanism for pressing down packaging boxes on the gantry frame, a belt conveyor second located to the left of the gantry frame mounted on the top of the belt conveyor body, and electric slide rails located inside the gantry frame mounted on both the front and rear sides of the belt conveyor body, with slide plates connected to the sliders of both electric slide rails, and a lid closing mechanism on both slide plates. The lid closing mechanism includes a lifting plate slidably connected to the slide plate via a guide rod first, and both the lifting plate and the slide plate are slidably connected via the guide rod second. The conveyor belt is connected to a sliding plate with a clamp. Both the lifting plate and the sliding plate are equipped with screw motors to drive the sliding plates to move back and forth. An electric push rod is mounted on the sliding plate, and its extension rod is connected to the lifting plate. Two connecting plates are connected to the upper sliding plate, and a support plate is rotatably connected between the two connecting plates via a rotating shaft to support the lid. The frame of the second conveyor belt has cavities on both the front and rear sides for the support plate to move. A drive assembly is located on the upper sliding plate to drive the rotating shaft to rotate the support plate up and down. A blocking mechanism is located on the right side of the frame of the second conveyor belt to prevent the lid and body from moving together.

[0013] Preferably, the blocking mechanism includes a mounting plate connected to the right side of the frame of the second belt conveyor. A double-headed cylinder is mounted on the right side of the mounting plate. Baffles are connected to the telescopic rods on both sides of the double-headed cylinder. Pressure sensors are mounted on the left side of both baffles.

[0014] Preferably, the clamp includes a bidirectional lead screw rotatably connected to the sliding plate, and two clamping plates are threadedly connected to the bidirectional lead screw. The clamping plates are slidably connected to the sliding plate via a slide rod. Push blocks are connected to the sides of the two clamping plates that are close to each other, and the sides of the clamping plates that are away from the sliding plate on the same side are bent outward.

[0015] Preferably, the drive assembly includes a guide rail and an L-shaped plate. Two guide rails are connected to the side of the upper sliding plate opposite to the lifting plate on the same side. An L-shaped plate is slidably connected inside the guide rails. A rack is connected to the L-shaped plate. A spring is connected between the upper sliding plate and the L-shaped plate on it. Two gear shafts are rotatably connected to the side of the upper sliding plate near the lifting plate on the same side. The gears on the gear shafts mesh with the rack on the same side. The gear shafts and the rotating shaft on the same side are connected by a transmission belt.

[0016] Preferably, the pressing mechanism includes a pressing plate that is slidably connected to the gantry frame via a slide rod. A drive cylinder is installed on the top of the gantry frame, and the telescopic rod of the drive cylinder is connected to the pressing plate to drive the pressing plate to move up and down to press down the packaging box.

[0017] Preferably, the pressure plate includes a connecting plate connected to the bottom end of a slide rod. A pressure plate is slidably connected to the connecting plate via a slide rod. A spring is spaced between the top of the pressure plate and the bottom of the connecting plate. An inverted U-shaped connecting block is connected to the middle of the top of the connecting plate. The telescopic rod of the driving cylinder is connected to the inverted U-shaped connecting block. A nut located inside the inverted U-shaped connecting block is embedded in the middle of the top of the connecting plate. An adjusting screw is threaded into the nut. The bottom end of the adjusting screw contacts the top of the pressure plate.

[0018] Preferably, the frame of the second belt conveyor is provided with an intermittent feeding mechanism. The intermittent feeding mechanism includes two rotating shafts, one upper and one lower, rotatably connected to the frame of the second belt conveyor. Each of the two rotating shafts is connected to a swing plate. Each of the two swing plates is hinged to a baffle plate on its front side. The baffle plate is located to the left of the clamp. The upper baffle plate is located on the upper side of the conveyor belt of the second belt conveyor, and the lower baffle plate is located on the upper side of the conveyor belt of the first belt conveyor. Each of the two baffle plates is hinged to a connecting rod on its rear side. The rear side of the connecting rod is hinged to the frame of the second belt conveyor. A stepper motor is installed on the frame of the second belt conveyor. The output shaft of the stepper motor is connected to the lower rotating shaft. The rear sides of the two swing plates are hinged together. A reflective photoelectric sensor is installed at the bottom of the lower baffle plate.

[0019] Preferably, the bottom of the pressure plate is connected to a rubber pad for cushioning and protecting the packaging box.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The invention achieves automatic assembly of the lid and body of the box through the lid closing mechanism and automatic pressing operation of the packaging box through the pressing mechanism. Thus, the invention realizes a fully automated process from the assembly of the lid and body of the box to the pressing operation, which not only reduces human intervention but also significantly improves production efficiency and ensures the consistency and stability of product quality.

[0022] 2. The height of the pressure plate on the pressure plate is adjustable to accommodate top and bottom lid packaging boxes of different heights. There is no need to adjust the stroke of the drive cylinder to accommodate top and bottom lid packaging boxes of different heights, making operation simpler, more convenient and faster.

[0023] 3. By intermittently swinging the upper and lower baffles, intermittent material feeding is achieved, ensuring that the box lid and box body enter the assembly position one by one in an orderly manner. This ensures the orderly assembly of the box lid and box body, thereby ensuring the smooth operation of the box pressing operation, effectively avoiding congestion on the production line, and ensuring that the entire production process is smoother, more efficient and safer.

Detailed Implementation

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] See Figure 1 An automatic box pressing machine includes a belt conveyor 1. A gantry frame 3 is connected to the right side of the body 11 of the belt conveyor 1. The gantry frame 3 is equipped with a pressing mechanism for pressing down the packaging box. A belt conveyor 2 is installed on the top of the body 11 of the belt conveyor 1, located to the left of the gantry frame 3. The belt conveyor is prior art and will not be described in detail here. The width of the conveyor belt 22 of the belt conveyor 2 is one-third of the width of the conveyor belt 12 of the belt conveyor 1. Electric slide rails 8 are installed on both the front and rear sides of the body 11 of the belt conveyor 1, located inside the gantry frame 3. Slide plates 5 are connected to the sliders of the two electric slide rails 8. A lid closing mechanism is provided on both slide plates 5. A blocking mechanism for blocking the lid 01 and the box body 02 is provided on the right side of the frame 21 of the belt conveyor 2.

[0037] See Figures 4-5The lid-closing mechanism includes four guide rods 61 connected to the top of the slide plate 5. A lifting plate 62 is slidably connected between the four guide rods 61. Two left and right guide rods 63 are connected to both the side of the lifting plate 62 facing the belt conveyor 2 and the side of the slide plate 5 facing the belt conveyor 1. A sliding plate 64 is slidably connected between the left and right guide rods 63. A clamp 65 is provided on the sliding plate 64. The upper and lower clamps 65 are used to clamp the lid 01 and the body 02, respectively. The clamp 65 includes a bidirectional lead screw 651 rotatably connected to the sliding plate 64. Two left and right clamping plates 652 are threaded onto the bidirectional lead screw 651. 2. Each side of the two adjacent plates is connected to a sliding rod 654, which is slidably connected to the sliding plate 64. Push blocks 653 are connected to the adjacent sides of the two clamping plates 652. The side of the clamping plate 652 away from the sliding plate 64 on the same side is bent outwards. Both the lifting plate 62 and the sliding plate 5 are equipped with screw motors 66. Screw motors 66 are existing technology and will not be described in detail here. The screw on the screw motor 66 is threadedly connected to the corresponding sliding plate 64, used to drive the sliding plate 64 on each to move back and forth. Two electric push rods 67 are installed on the side of the sliding plate 5 facing away from the belt conveyor 1. The telescopic rods of the electric push rods 67 are connected to the lifting plate 64. The upper sliding plate 64 is connected to a lowering plate 62. Two connecting plates 68 are connected to the upper sliding plate 64 on the side facing the belt conveyor 2. A rotating shaft 69 is rotatably connected between the two connecting plates 68. Two support plates 610 for supporting the lid 01 are connected to the rotating shaft 69. The side of the support plate 610 facing the belt conveyor 2 is inclined to allow it to move under the lid 01 and support it. The frame 21 of the belt conveyor 2 has two accommodating cavities 23 on the right side for the support plates 610 to move. A driving assembly is provided on the upper sliding plate 64 to drive the rotating shaft 69 to rotate the support plates 610 up and down. The moving assembly includes a guide rail 611 and an L-shaped plate 612. The upper sliding plate 64 is connected to two guide rails 611 on the side opposite to the lifting plate 62 on the same side. The L-shaped plate 612 is slidably connected inside the guide rail 611. A rack 613 is connected to the L-shaped plate 612. A spring 614 is connected between the upper sliding plate 64 and the L-shaped plate 612 on the same side. The upper sliding plate 64 is rotatably connected to two gear shafts 615 on the side near the lifting plate 62 on the same side. The gear on the gear shaft 615 meshes with the rack 613 on the same side. A transmission belt 616 is connected between the shaft of the gear shaft 615 and the rotating shaft 69 on the same side via a pulley.

[0038] See Figures 2-3 The blocking mechanism includes a mounting plate 71 connected to the right side of the frame 21 of the belt conveyor 2. A double-headed cylinder 72 is mounted on the right side of the mounting plate 71. Baffles 73 are connected to the telescopic rods on both sides of the double-headed cylinder 72. Pressure sensors 74 are mounted on the left side of both baffles 73.

[0039] See Figure 1 and Figure 8 The pressing mechanism includes four sliding rods 41 spaced and slidably connected to the top of the gantry frame 3. A pressing plate 43 is connected between the bottom ends of the four sliding rods 41. A drive cylinder 42 is installed on the top of the gantry frame 3 between the four sliding rods 41. The telescopic rod of the drive cylinder 42 is connected to the pressing plate 43 to drive the pressing plate 43 to move up and down to press down the packaging box. The pressing plate 43 includes a connecting plate 431 connected to the bottom ends of the four sliding rods 41. Sliding rods 433 are slidably connected to all four sides of the connecting plate 431. A pressing plate 434 is connected between the bottom ends of the four sliding rods 433. A spring 435 is fitted on each of the four sliding rods 433. The ends are respectively connected to the top of the pressure plate 434 and the bottom of the connecting plate 431. The top of the connecting plate 431 is connected to the middle of the inverted U-shaped connecting block 432. The telescopic rod of the drive cylinder 42 is connected to the inverted U-shaped connecting block 432. The top of the connecting plate 431 is embedded in the middle of the nut 436 located inside the inverted U-shaped connecting block 432. The nut 436 is connected to the adjusting screw 437 by its internal thread. The bottom end of the adjusting screw 437 contacts the top of the pressure plate 434. The bottom of the pressure plate 434 is connected to the rubber pad 10 to provide cushioning protection for the top and bottom lid packaging box, so as to prevent the pressure plate 434 from directly and rigidly squeezing the top and bottom lid packaging box, thereby protecting the top and bottom lid packaging box from damage.

[0040] Place the lid 01 on the conveyor belt 22 of the second belt conveyor 2, and place the box body 02 on the conveyor belt 12 of the first belt conveyor 1. Control the first belt conveyor 1 and the second belt conveyor 2 to work intermittently to transport the lid 01 and the box body 02 to the right intermittently, and make the first belt conveyor 1 and the second belt conveyor 2 run at the same speed to ensure that the lid 01 and the box body 02 are transported to the right synchronously. When the lid 01 and body 02 move to the right and come into contact with the baffle 73, they are blocked by the baffle 73 and cannot move further to the right. This allows the lid 01 and body 02 to be precisely aligned with the clamp 65. After being blocked by the baffle 73, the lid 01 and body 02 press the pressure sensor 74. The pressure sensor 74 senses that the pressure has reached the preset value and sends a signal to the controller (not shown in the figure, the controller is existing technology and will not be described here). After receiving the signal, the controller controls the lead screw motor 66 to work, so as to drive the sliding plate 64 to move its upper parts towards the baffle 73. The clamp 652 on the upper clamp 65 moves and fits on the outer wall of the lid 01. The clamp 652 on the lower clamp 65 moves and fits on the outer wall of the body 02. The support plate 610 moves to the lower side of the lid 01 to support the lid 01. Because the side of the clamping plate 652 away from the sliding plate 64 on the same side is bent outward, the clamping plate 652 can smoothly fit onto the outer wall of the lid 01 and the body 02, so as to avoid directly and rigidly squeezing the lid 01 and the body 02, which would cause damage to the lid 01 and the body 02. The push block 653 on the clamping fixture can push the lid 01 and the body 02 to be aligned in the front and back positions, thereby ensuring the accuracy of the subsequent assembly of the lid 01 and the body 02. The distance between the two clamping plates 652 can be adjusted by rotating the two-way screw 651 to accommodate lids 01 and bodies 02 of different sizes. After the lid 01 and body 02 are clamped by the clamp 65, the double-headed cylinder 72 is first controlled to drive the upper and lower baffles 73 to move closer together and disengage from the lid 01 and body 02. Then, the electric slide rail 8 is controlled to drive the slide plate 5 to move to the right, thereby driving the lifting plate 62 to move to the right synchronously through the guide rod 61, so that the four clamps 65 move to the right synchronously, and thus the lid 01 and body 02 move to the right synchronously. The lid 01 moves to the right and disengages from the belt conveyor 2. Subsequently, the electric push rod 67 is controlled to drive the lifting plate 62 to move the upper sliding plate 64 down, thereby driving the upper clamp 65, support plate 610 and L-shaped plate 612 down, thus causing the lid 01 to move down. When the L-shaped plate 612 moves down to contact the lower sliding plate 64, the L-shaped plate 612 and the rack 613 can no longer move down, so the upper sliding plate 64 continues to move down, stretching the spring 614.The rack 613 cannot move down, but the gear shaft 615 continues to move down following the upper sliding plate 64. Through the meshing of the rack 613 and the gear, the gear shaft 615 is driven to rotate. The rotation of the gear shaft 615 drives the rotating shaft 69 to rotate through the transmission belt 616. The rotation of the rotating shaft 69 drives the support plate 610 to rotate downward and release the box cover 01. The box cover 01 then moves down along the support plate 610 and closes on the box body 02, realizing the automatic assembly of the box cover 01 and the box body 02. This eliminates the need for manual assembly of the box cover 01 and the box body 02 one by one, reducing human intervention, reducing labor intensity, and improving production efficiency.

[0041] After assembly, the top and bottom lid packaging box continues to move to the right until it is directly below the pressing plate 43. At this time, the upper sliding plate 64 and its components move down to a position below the pressing plate 43, so they do not obstruct the pushing of the assembled top and bottom lid packaging box directly below the pressing plate 43. After the assembled top and bottom lid packaging box is pushed directly below the pressing plate 43, the control screw motor 66 is activated to drive the sliding plate 64 and its components to move away from the packaging box, thereby causing the clamp 65 to move away from the packaging box and disengage from it. Then, the control drive cylinder 42 drives the pressing plate 43 to move down and up reciprocally. When the pressing plate 43 moves down, it presses down on the packaging box through its upper pressing plate 434. Thus, this device realizes a fully automated process from the assembly of the lid 01 and the body 02 to the pressing of the box, which not only reduces human intervention but also significantly improves production efficiency and ensures the consistency and stability of product quality. While performing the pressing operation, the electric slide rail 8 is controlled to drive the slide plate 5 to move to the left and reset, thereby driving the clamp 65 to move to the left and reset. When the clamp 65 moves away from the pressing plate 43 to the left, the electric push rod 67 is controlled to drive the lifting plate 62 to drive the upper sliding plate 64 to move upward and reset, so as to drive the upper clamp 65, support plate 610 and L-shaped plate 612 to move upward and reset. At this time, under the reset action of the second spring 614, the L-shaped plate 612 drives the rack 613 to move downward and reset in the guide rail 611. The downward movement of the rack 613 pushes the gear shaft 615 to reverse. The reverse rotation of the gear shaft 615 drives the rotating shaft 69 to reverse through the transmission belt 616. The reverse rotation of the rotating shaft 69 drives the support plate 610 to rotate upward and reset. After the sliding plate 5 drives the lid-closing mechanism to move to the left and reset, the double-headed cylinder 72 drives the upper and lower baffles 73 to move away from each other, thus blocking the next lid 01 and body 02. Then, the belt conveyor 1 and belt conveyor 2 continue to work, conveying the next lid 01 and body 02 to the right, and conveying the pressed packaging box to the right to the next process. Rotating the adjusting screw 437 will cause the adjusting screw 437 to move down, pushing the pressure plate 434 down and stretching the spring 435. Reversing the adjusting screw 437 will cause the adjusting screw 437 to move up. Under the reset action of the spring 435, the pressure plate 434 can be pulled up. This allows for adjustment of the height of the pressure plate 434. The adjustable height of the pressure plate 434 can adapt to different heights of top and bottom lid packaging boxes without adjusting the stroke of the drive cylinder 42 to adapt to different heights of top and bottom lid packaging boxes, making the operation simpler, more convenient and faster.

[0042] See Figures 9-10The frame 21 of the belt conveyor 2 is equipped with an intermittent feeding mechanism. The intermittent feeding mechanism includes two rotating shafts 91, one upper and one lower, which are rotatably connected to the frame 21 of the belt conveyor 2. Each of the two rotating shafts 91 is connected to a swing plate 92. Each of the two swing plates 92 is hinged to a baffle plate 93 on its front side. The baffle plate 93 is located to the left of the clamp 65. The upper baffle plate 93 is located on the upper side of the conveyor belt 22 of the belt conveyor 2, and the lower baffle plate 93 is located on the upper side of the conveyor belt 12 of the belt conveyor 1. Each of the two baffle plates 93 is hinged to a connecting rod 94 on its rear side. The rear side of the connecting rod 94 is hinged to the frame 21 of the belt conveyor 2. A stepper motor 95 is installed on the frame 21 of the belt conveyor 2. The output shaft of the stepper motor 95 is connected to the lower rotating shaft 91. A connecting rod 97 is hinged between the rear sides of the two swing plates 92. A reflective photoelectric sensor 96 is installed at the bottom of the lower baffle plate 93.

[0043] The transmitter and receiver of the reflective photoelectric sensor 96 are located on the same side. It uses a reflector to reflect the light beam. The reflective photoelectric sensor 96 is existing technology and will not be described in detail here. When the box body 02 passes under the reflective photoelectric sensor 96, the light beam is blocked. When the box body 02 moves away from under the reflective photoelectric sensor 96, the light beam is not blocked, and the reflective photoelectric sensor 96 detects the light beam. The reflective photoelectric sensor 96 sends a signal to the controller. After receiving the signal, the controller controls the stepper motor 95 to drive the lower rotating shaft 91 to rotate, thereby causing the lower swing plate 92 to swing downward. The downward swing of the lower swing plate 92 drives the upper swing plate 92 to swing downward through the connecting rod 97, thereby causing the upper and lower baffles 93 to swing downward synchronously. The connecting rod 94 can stabilize the baffles 93, so that the baffles 93 always remain horizontal when swinging up and down, avoiding the baffles 93 from hitting the belt conveyor 1 and belt conveyor 2 when swinging up and down. The upper baffle 93, while maintaining a horizontal position, swings downward to block the next box cover 01, and the lower baffle 93, while maintaining a horizontal position, swings downward to block the next box body 02. This intermittent material feeding ensures that the box cover 01 and box body 02 enter the assembly position one by one in an orderly manner, thereby ensuring the orderly assembly of the box cover 01 and box body 02. This, in turn, ensures the smooth progress of the box pressing operation, effectively avoids congestion on the production line, and guarantees a smoother, more efficient, and safer production process. After the pressing operation of a top and bottom lid packaging box is completed, the stepper motor 95 is controlled to drive the lower rotating shaft 91 to reverse, thereby driving the lower swing plate 92 to swing upward. The upward swing of the lower swing plate 92 drives the upper swing plate 92 to swing upward through the connecting rod 97, so that the upper and lower baffles 93 swing upward synchronously to reset and disengage from the lid 01 and the box body 02, releasing the lid 01 and the box body 02. Then, the belt conveyor 1 and belt conveyor 2 continue to work, conveying the next lid 01 and box body 02 to the right to align with the clamp 65.

[0044] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
