Description

Technical Field

[0001] The present invention relates to the technical field of box pressing machines, in particular to an automatic box pressing machine. Background Art

[0002] The box with lid and top is a classic packaging form, which is widely used in the packaging of various high-end products with its elegant appearance and practical functions. It consists of the upper lid symbolizing "sky" and the lower body symbolizing "earth", which combine to form a complete packaging box. This design is not only beautiful, but also provides good protection performance, suitable for the outer packaging of gifts, cosmetics, electronic products and other commodities.

[0003] Pressing is an indispensable step in making lid packaging boxes. Its main purposes include:

[0004] 1. Enhance structural strength: Pressing the box can make the various components of the top and bottom lid gift box tightly combined, improve the overall strength of the gift box, and prevent deformation during transportation or handling.

[0005] 2. Improve appearance quality: After the box pressing process, the surface of the gift box is smoother and smoother, the lines are clearer and sharper, which can present a better visual effect and give 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 to ensure that each finished product meets the design requirements and achieve the purpose of standardized production.

[0007] At present, the box pressing operation is generally performed on the top and bottom lid packaging boxes through a box pressing machine. The existing box pressing machine is usually composed of a belt conveyor, a cylinder and a box pressing plate. The working process is as follows: first, the lid and the box body of the top and bottom lid packaging box are manually assembled together, and then the assembled top and bottom lid packaging box is placed on the belt conveyor, and the belt conveyor conveys the assembled top and bottom lid packaging box to the bottom of the box pressing plate, and then the cylinder drives the box pressing plate to rise and fall to perform the box pressing operation on the top and bottom lid packaging box. The pressed top and bottom lid packaging box is finally conveyed to the next process by the belt conveyor.

[0038] See also Figure 2-Figure 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 installed 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, and pressure sensors 74 are installed on the left sides of the two baffles 73.

[0039] See also Figure 1 and Figure 8 The pressing mechanism includes four sliding bars 41 connected to the top of the gantry 3 in an interval sliding manner, a box pressing plate 43 is connected between the bottom ends of the four sliding bars 41, a driving cylinder 42 is installed on the top of the gantry 3 and is located between the four sliding bars 41, and the telescopic rod of the driving cylinder 42 is connected to the box pressing plate 43 to drive the box pressing plate 43 to move up and down to press the packaging box, and the box pressing plate 43 includes a connecting plate 431 connected to the bottom ends of the four sliding bars 41, and sliding bars 433 are slidably connected to the four sides of the connecting plate 431, and a pressing plate 434 is connected between the bottom ends of the four sliding bars 433, and a spring 435 is sleeved on the four sliding bars 433, and the two ends of the spring 435 are The ends are respectively connected to the top of the pressing plate 434 and the bottom of the connecting plate 431. The middle of the top of the connecting plate 431 is connected with an inverted U-shaped connecting block 432. The telescopic rod of the driving cylinder 42 is connected to the inverted U-shaped connecting block 432. A nut 436 located on the inner side of the inverted U-shaped connecting block 432 is embedded in the middle of the top of the connecting plate 431. The inner thread of the nut 436 is connected with an adjusting screw 437. The bottom end of the adjusting screw 437 contacts the top of the pressing plate 434. The bottom of the pressing plate 434 is connected with a rubber pad 10 to provide buffering protection for the top and bottom cover packaging box to prevent the pressing plate 434 from directly and rigidly squeezing the top and bottom cover packaging box, thereby protecting the top and bottom cover packaging box from damage.

[0040] Place the box cover 01 on the conveyor belt 22 of belt conveyor 2, and place the box body 02 on the conveyor belt 12 of belt conveyor 1, control belt conveyor 1 and belt conveyor 2 to work intermittently, so as to convey the box cover 01 and the box body 02 to the right intermittently, and make belt conveyor 1 and belt conveyor 2 run at the same speed to ensure that the box cover 01 and the box body 02 are conveyed to the right synchronously. When the box cover 01 and the box body 02 move to the right and contact the baffle 73, they are blocked by the baffle 73 and cannot move further to the right, so that the box cover 01 and the box body 02 can be accurately aligned with the clamp 65. After the box cover 01 and the box body 02 are blocked by the baffle 73, the pressure sensor 74 is squeezed. The pressure sensor 74 senses that the pressure reaches a preset value, and the pressure sensor 74 sends a signal to the controller (the controller is not shown in the figure, the controller is prior art, and is not repeated here). After receiving the signal, the controller controls the screw motor 66 to work to drive the sliding plate 64 to drive its upper component to move in the direction close to the baffle 73, and the clamp 652 on the upper clamp 65 moves accordingly and is sleeved on the outer wall of the box cover 01, and the clamp 652 on the lower clamp 65 moves accordingly and is sleeved on the outer wall of the box body 02, and the support plate 610 moves to the lower side of the box cover 01 to support the box cover 01. Since the side of the clamp 652 is bent outward away from the sliding plate 64 on the same side, the clamp 652 can be smoothly mounted on the outer wall of the box cover 01 and the box body 02 to avoid direct hard squeezing of the box cover 01 and the box body 02, which would cause damage to the box cover 01 and the box body 02. The push block 653 on the clamp 65 can push the box cover 01 and the box body 02 to be centered in the front and back directions, thereby ensuring the accuracy of the subsequent assembly of the box cover 01 and the box body 02. The distance between the left and right clamps 652 can be adjusted by rotating the bidirectional screw rod 651 to accommodate box covers 01 and box bodies 02 of different sizes. After the box cover 01 and the box 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 approach each other and separate from the box cover 01 and the box body 02, and then the electric slide rail 8 is controlled to drive the slide plate 5 to move rightward, thereby driving the lifting plate 62 to move rightward synchronously through the guide rod 1 61, so that the four clamps 65 move rightward synchronously, and then the box cover 01 and the box body 02 move rightward synchronously, and the box cover 01 moves rightward and separates from the belt conveyor 2 2. Then the electric push rod 67 is controlled to drive the lifting plate 62 to drive the upper sliding plate 64 to move downward, so as to drive the upper clamp 65, the support plate 610 and the L-shaped plate 612 to move downward, so that the box cover 01 moves downward. When the L-shaped plate 612 moves downward to contact the lower sliding plate 64, the L-shaped plate 612 and the rack 613 cannot move downward further, so that the upper sliding plate 64 continues to move downward to stretch the spring 2 614.The rack 613 cannot move downward while the gear shaft 615 continues to move downward with the upper sliding plate 64, and the gear shaft 615 is driven to rotate through the meshing action of the rack 613 and the gear. The rotation of the gear shaft 615 drives the rotating shaft 69 to rotate through the transmission belt 616, and the rotation of the rotating shaft 69 drives the support plate 610 to rotate downward to loosen the box cover 01, and the box cover 01 then moves down along the support plate 610 and covers the box body 02, thereby realizing automatic assembly of the box cover 01 and the box body 02, thereby eliminating the need for manual assembly of the box cover 01 and the box body 02 of the top and bottom cover packaging box one by one, thereby reducing human intervention, reducing labor intensity, and improving production efficiency.

[0041] The assembled top and bottom cover packaging box continues to move rightward to just below the box pressing plate 43, and at this time, the upper sliding plate 64 and its upper parts all move down to be located below the box pressing plate 43, so there will be no obstruction in pushing the assembled top and bottom cover packaging box to just below the box pressing plate 43. After the assembled top and bottom cover packaging box is pushed to just below the box pressing plate 43, the screw motor 66 is controlled to work to drive the sliding plate 64 to drive its upper parts to move away from the packaging box, thereby driving the clamp 65 to move away from the packaging box and disengage from the packaging box, and then the driving cylinder 42 is controlled to drive the box pressing plate 43 to move back and forth downward and upward. When the box pressing plate 43 moves down, it presses down the packaging box through its upper pressing plate 434, so that the device realizes a fully automated process from the assembly of the box cover 01 and the box body 02 to the box pressing, which not only reduces human intervention, but also significantly improves production efficiency and ensures the consistency and stability of product quality. While the box pressing operation is being performed, 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 to the left away from the box pressing plate 43, the electric push rod 67 is controlled to drive the lifting plate 62 to drive the upper sliding plate 64 to move up and reset, so as to drive the upper clamp 65, the support plate 610 and the L-shaped plate 612 to move up and reset. At this time, under the reset action of spring 2 614, the L-shaped plate 612 drives the rack 613 to move down and reset in the guide rail 611, and the rack 613 moves downward to push the gear shaft 615 to reverse. The gear shaft 615 reverses and drives the rotating shaft 69 to reverse through the transmission belt 616. The reversal of the rotating shaft 69 drives the support plate 610 to rotate upward and reset. When the slide plate 5 drives the cover closing mechanism to move to the left and reset, the double-headed cylinder 72 is controlled to drive the upper and lower baffles 73 to move away from each other to block the next box cover 01 and the box body 02, and then the belt conveyor 1 and the belt conveyor 2 continue to work, convey the next box cover 01 and the box body 02 to the right, and convey the box after pressing to the right to the next process. The adjusting screw 437 is turned to move the adjusting screw 437 downward to push the pressing plate 434 downward, stretch the spring 1 435, reverse the adjusting screw 437 to move the adjusting screw 437 upward, and under the reset action of the spring 1 435, the pressing plate 434 can be pulled upward, so that the height of the pressing plate 434 can be adjusted. The height of the pressing plate 434 is adjustable to adapt to the top and bottom lid packaging boxes of different heights, and there is no need to adjust the stroke of the driving cylinder 42 to adapt to the top and bottom lid packaging boxes of different heights, and the operation is simpler, more convenient and faster.

[0042] See also Figure 9-10An intermittent unloading mechanism is provided on the frame 21 of the belt conveyor 2, and the intermittent unloading mechanism includes two upper and lower rotating shafts 91 rotatably connected to the frame 21 of the belt conveyor 2, and the two rotating shafts 91 are connected with swing plates 92, and the front sides of the two swing plates 92 are hinged with baffles 93, and the baffles 93 are located on the left side of the clamp 65. The upper baffle 93 is located on the upper side of the conveying belt 22 of the belt conveyor 2, and the lower baffle 93 is located on the upper side of the conveying belt 12 of the belt conveyor 1. The top rear sides of the two baffles 93 are hinged with connecting rods 94, and the rear side of the connecting rods 94 is hinged on the frame 21 of the belt conveyor 2, and a stepper motor 95 is installed on the frame 21 of the belt conveyor 2, and the output shaft of the stepper motor 95 is connected to the lower rotating shaft 91, and a connecting rod 97 is hinged between the rear sides of the two swing plates 92, and a reflective photoelectric sensor 96 is installed at the bottom of the lower baffle 93.

[0043] The transmitter and receiver of the reflective photoelectric sensor 96 are located on the same side, and the light beam is reflected by a reflective plate. The reflective photoelectric sensor 96 is a prior art 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 the bottom of 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 2 91 to rotate, thereby driving the lower swing plate 92 to swing downward. The lower swing plate 92 swings downward and drives the upper swing plate 92 to swing downward through the connecting rod 2 97, thereby driving the upper and lower baffles 93 to swing downward synchronously. The baffle 93 can be stabilized by the connecting rod 1 94, so that the baffle 93 always remains in a horizontal state when swinging up and down, avoiding the baffle 93 from hitting the belt conveyor 1 and the belt conveyor 2 2 when swinging up and down. The upper baffle plate 93 keeps the horizontal state and swings downward to block the next box cover 01, and the lower baffle plate 93 keeps the horizontal state and swings downward to block the next box body 02, thereby realizing intermittent material discharge to ensure that the box cover 01 and the 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 the box body 02 one by one, and then ensuring the smooth progress 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. After completing the box pressing operation of a top and bottom cover packaging box, control the stepper motor 95 to drive the lower rotating shaft 2 91 to reverse, thereby driving the lower swing plate 92 to swing upward, and the lower swing plate 92 swings upward to drive the upper swing plate 92 to swing upward through the connecting rod 2 97, so that the upper and lower baffles 93 swing upward synchronously to reset and disengage from the box cover 01 and the box body 02, and then the box cover 01 and the box body 02 are released, and then the belt conveyor 1 and the belt conveyor 2 continue to work to convey the next box cover 01 and the box body 02 to the right to align with the clamp 65.

[0044] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
