Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a positioning paperboard pressing mechanism of a box nailing machine. Background Art

[0002] The box nailing machine is a special equipment for the automatic nailing and forming of cartons. When the equipment is working, two pieces of cardboard are first conveyed by two chains. After the cardboard passes through the folding mechanism, the cardboard can be driven to bend along the crease, and then the bent cardboard is sent to the nailing station, and the two cardboards are nailed together by the nail gun to realize the forming of the carton. In order to ensure the accuracy of the position of the cardboard during nailing, it is necessary to set a cardboard pressing mechanism to position and press the cardboard on the positioning piece. The cardboard pressing mechanism mainly includes a mobile frame, and a pressing wheel is arranged on the mobile frame. A corresponding small spring is arranged between each pressing wheel and the mobile frame. The defect of this pressing mechanism is that the pressure applied by each pressing wheel to the cardboard is applied by an independent small spring, and the pressure of each independent small spring is limited, and it is impossible to ensure that the cardboard is pressed on the positioning piece, especially when the cardboard is about to leave the nailing station, only the rear several pressing wheels are elastically pressed on the cardboard. At this time, it is difficult to ensure that the cardboard can be stably positioned and pressed, resulting in the possible deviation of the cardboard position, affecting the accuracy of the cardboard nailing.

[0025] Example

[0026] like Figure 1-5As shown, the utility model discloses a positioning cardboard pressing mechanism of a box nailing machine, including a swing plate 2, on which a pressing wheel 1 is arranged, and the middle part of the swing plate 2 is swingably arranged on a moving frame 3, and an elastic member is arranged between the moving frame 3 and the moving seat 10, and the moving seat 10 is connected to a moving driving assembly. The moving driving assembly includes a driving cylinder 7, and the piston rod of the driving cylinder 7 is connected to the moving seat 10. The moving seat 10 can be driven to move by controlling the driving cylinder 7. Of course, in addition to using the cylinder, a common linear driving mechanism such as a linear motor, a motor-driven cam structure, a gear rack structure, and a synchronous belt structure can also be used to drive the moving seat 10 to move. Furthermore, a limit assembly is provided corresponding to the moving frame 3, and the limit assembly can limit the moving stroke of the moving frame 3 to ensure that the moving frame 3 will not fall off. The limiting assembly includes a limiting column 11 arranged on the mobile frame 3, the limiting column 11 passes through the mobile seat 10, a first limiting block 13 is arranged at one end of the limiting column 11, and a limiting step 14 that can be abutted against the first limiting block is arranged on the mobile seat 10. When the limiting step 14 abuts against the first limiting block 13, it is the maximum movement range of the mobile seat 10. At this time, the mobile seat 10 is limited to ensure that the mobile seat 10 will not fall off. The elastic member is a spring 9, which is sleeved on the outside of the limiting column 11 and the mobile seat 10. The limiting column 11 is externally screwed with a first adjusting nut 21. The spring 9 is arranged between the first adjusting nut 21 and the mobile seat 10. The elastic force of the spring 9 can be adjusted by rotating the first adjusting nut 21. A guide column 4 is arranged on the mobile frame 3, and a guide seat 5 cooperating with the guide column 4 is arranged on the frame 6 to guide the movement of the mobile frame 3 and improve its movement stability. The movable frame 3 is provided with a limit rod 16, which can abut against the swing plate 2 to limit the swing angle of the swing plate 2, so as to ensure that the swing plate 2 will not be unable to stably press the cardboard on the positioning member due to excessive swing amplitude. It also includes swing seats 12 arranged on the swing plate 2, the pressure wheel 1 is arranged on the swing seats 12, and the middle part of the swing seat is rotatably arranged on the swing plate 2. By providing multiple swing seats 12, the flexibility of the pressure wheel 1 at different positions can be improved, and it can be further ensured that each part of the cardboard can be stably pressed on the positioning member. Example

[0027] like Figure 6As shown, the difference between this embodiment and embodiment 1 is that the limiting assembly can also be a second limiting block 17 set on the guide column 4, and the second limiting block 17 can be against the guide seat 5. When the mobile frame 3 drives the guide column 4 to move and makes the second limiting block 17 against the knife seat 5, the movement of the mobile seat 10 is limited to ensure that the mobile frame 3 will not fall off. In addition, a screw rod 18 is provided on the mobile seat 10, and a second adjusting nut 19 is screwed on the screw rod 18. The elastic member is a spring 9 sleeved outside the screw rod 18, and the spring 9 is located between the second adjusting nut 19 and the mobile frame 3. The elastic pressure of the spring 9 can be adjusted by rotating the second adjusting nut 19. Example

[0028] like Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the elastic member includes a pressure regulating cylinder 20 arranged on the moving seat 10, the piston rod of the pressure regulating cylinder 20 is connected to the moving frame 3, and the pressure regulating cylinder 20 is connected to the air pump through a pressure regulating valve. When the pressure regulating cylinder is used, the elastic pressure applied to the moving frame 3 can be adjusted by adjusting the pressure in the pressure regulating cylinder 20 through the pressure regulating valve, and this cylinder connection method no longer requires additional setting of a limit assembly to limit the displacement of the moving frame 3, and can directly ensure that the moving frame 3 will not fall out.

[0029] The working principle of the utility model is as follows: when the bent cardboard is sent to the nailing box station, the part of the cardboard to be pressed passes through the limit plate 22 and the support plate 23, the driving cylinder 7 drives the moving seat 10 to move, and the spring 9 (or the pressure regulating cylinder 20) drives the moving frame 3 to move toward the cardboard, so that the pressing wheel 1 on the swing plate 2 can press the cardboard on the support plate 23, and at this time the spring 9 (or the piston rod of the pressure regulating cylinder 20) is squeezed and compressed, so that the nailing end of the cardboard is elastically pressed on the support plate 23 of the nailing box station to achieve the positioning of the nailing, with the forward conveying of the cardboard, when the cardboard continues to move away from the nailing box station, the corresponding pressing wheel can still press the cardboard, and the swing plate 2 will also swing to a suitable angle accordingly, so that the pressing wheel 1 can press the cardboard on the positioning piece with a suitable pressure until the cardboard completely leaves the pressing wheel 1, ensuring that the cardboard always maintains an elastic positioning and pressing state from entering the nailing box station to leaving the nailing box station, thereby ensuring the accuracy of the nailing position.

[0030] The structure of the utility model is that the swing plate is rotatably arranged on the moving frame, the swing plate is rotatably arranged on the moving frame, the pressure wheel is arranged on the swing plate, and the elastic member is arranged between the moving frame and the moving seat, so that the elastic pressure applied by the elastic member can be completely transmitted to the swing plate, no matter how many pressure wheels on the swing plate are in contact and squeeze the paperboard, it can be ensured that the pressure wheels have sufficient elastic pressure applied to the paperboard, and at the same time, the swing plate can be adaptively swung according to the reverse force of the pressure wheels, so that the paperboard can be positioned and pressed at the nail box station to ensure the accuracy of the subsequent nailing position, and will not be deformed due to excessive pressure.
