Description

Technical Field

[0001] The utility model relates to the technical field of packaging paperboard processing, in particular to a packaging press strip mechanism. Background Art

[0002] Packaging refers to the general name for containers, materials and auxiliary materials used according to certain technical methods to protect products during circulation, facilitate storage and transportation, and promote sales. Currently, the most commonly used packaging method on the market is paper box packaging.

[0003] In the production process of packaging cartons, flat cardboard needs to be glued to form cartons. Before gluing, the cardboard needs to be rolled to form creases to facilitate subsequent folding. Therefore, it is necessary to use a beading device to perform the beading operation. For example, the Chinese utility model patent with announcement number CN219338758U specifically discloses a double-sided beading mechanism for creases of packaging cartons.

[0004] However, during actual use of the above packaging press stripping mechanism, people will find that the device performs press stripping operations on the packaging cardboard through a press roller. However, when performing the press stripping operation, the packaging paper does not restrict it. When the press roller rolls the packaging cardboard, it is easy for the packaging cardboard to curl up, thereby affecting subsequent processing. Utility Model Content

A driving motor is arranged on the end of the slide rail, and the driving shaft of the driving motor is connected to the screw rod. A screw rod slider is threadedly connected to the screw rod, and a pressure strip plate is arranged under the screw rod slider. After the packaging cardboard is pressed by using the limiting pressure plate, the telescopic motor continuously outputs and the spring is compressed at the same time until the pressure strip plate contacts the packaging cardboard to perform the pressure strip operation. Before pressure stripping, the driving motor can be started to drive the screw rod to rotate, and the position of the pressure strip plate can be adjusted to realize the pressure strip operation at different positions.

[0008] Preferably, a baffle is provided on the side of the workbench, and the baffle serves to limit the side of the packaging cardboard.

[0009] Preferably, a rubber pad is provided on the limiting pressure plate, and the rubber pad is mainly used to play a buffering role to prevent the packaging cardboard from being crushed.

[0010] Preferably, a through long waist groove is provided on the upper surface of the U-shaped bracket at the side of the telescopic motor.

[0011] Preferably, a second positioning rod is symmetrically fixed on the pressure strip plate, the second positioning rod passes through the long waist groove and is fixed with a second positioning block, and the second positioning block is provided to limit the pressure strip plate. When the screw rod drives the pressure strip plate to move, the second positioning rod will slide in the long waist groove.

[0012] Preferably, the side edge of the slider is in contact with the inner wall of the slide rail, and a sliding connection is adopted between the slider and the slide rail, so as to restrict the slider and prevent the slider from rotating with the screw rod.

[0014] The utility model provides a limiting pressure plate to press the packaging cardboard on the workbench, and the telescopic motor continuously outputs to push the slide rail downward, and the spring is squeezed during the process, so that the pressure plate continuously descends and performs a pressure stripping operation on the packaging cardboard. During the process, since the packaging cardboard is pressed tightly by the limiting pressure plate, the phenomenon of edge warping of the packaging cardboard can be effectively avoided. Before the pressure stripping operation is performed, the driving motor can be used to drive the screw rod to rotate, so that the screw rod drives the slide block to move, and drives the pressure strip plate to move, so that the position of the pressure strip plate is adjusted, which effectively improves the practicability of the device.

[0022] See also Figure 1-3, the present utility model provides a technical solution: a pressing strip mechanism for packaging, including a bottom plate 1, a slide rail 7 and a limiting pressing plate 8. Above the bottom plate 1, there is a U-shaped bracket 4. In the middle of the bottom plate 1, there is a workbench 2. In the middle of the U-shaped bracket 4, there is a telescopic motor 6. The output end of the telescopic motor 6 is connected to the slide rail 7. Symmetrically fixed at positions near both ends on the side of the slide rail 7 are connecting blocks 10. A vertical first positioning rod 11 passes through the connecting block 10. At the end of the first positioning rod 11, there is a horizontal limiting pressing plate 8. At the top of the first positioning rod 11, there is a first positioning block 13. A spring 12 is sleeved outside the first positioning rod 11 between the limiting pressing plate 8 and the connecting block 10. Both ends of the spring 12 are fixed to the limiting pressing plate 8 and the connecting block 10 respectively. By placing the packaging cardboard on the workbench 2 and pushing the slide rail 7 down by the telescopic motor 6, the limiting pressing plate 8 is driven to descend and press the packaging cardboard tightly.

[0023] Furthermore, a lead screw 16 is arranged inside the slide rail 7. The end of the lead screw 16 is rotatably connected to the slide rail 7. At the end of the slide rail 7, there is a driving motor 17. The driving shaft of the driving motor 17 is connected to the lead screw 16. A lead screw slider 18 is threadedly connected to the lead screw 16. Below the lead screw slider 18, there is a pressing strip plate 9. After using the limiting pressing plate 8 to press the packaging cardboard tightly, the telescopic motor 6 continues to output, and at the same time, the spring 12 is compressed until the pressing strip plate 9 contacts the packaging cardboard for pressing strip operation. Before pressing the strip, the driving motor 17 can be started to drive the lead screw 16 to rotate to adjust the position of the pressing strip plate 9 so as to realize the pressing strip operation at different positions.

[0024] Furthermore, a baffle 3 is arranged on the side of the workbench 2, and the baffle 3 serves to limit the side of the packaging cardboard.

[0025] Furthermore, a rubber pad is arranged on the limiting pressing plate 8, and the arranged rubber pad mainly serves to play a buffering role to avoid damaging the packaging cardboard.

[0026] Furthermore, a through long waist groove 5 is opened on the upper surface of the U-shaped bracket 4 on the side of the telescopic motor 6.

[0027] Furthermore, symmetrically fixed on the pressing strip plate 9 are second positioning rods 14. The second positioning rods 14 pass through the long waist groove 5 and are fixed with second positioning blocks 15. The arranged second positioning blocks 15 serve to limit the pressing strip plate 9. When the lead screw 16 drives the pressing strip plate 9 to move, the second positioning rods 14 will slide in the long waist groove 5.

[0028] Furthermore, the side of the slider 18 is in contact with the inner wall of the slide rail 7, and the slider 18 and the slide rail 7 adopt a sliding connection to limit the slider 18 and prevent the slider 18 from rotating with the lead screw 16.

[0029] In summary, when the device is in use, it is only necessary to place the packaging cardboard on the workbench 2, use the side guard to limit the side of the packaging cardboard, and then start the telescopic motor 6, so that the telescopic motor 6 pushes the slide rail 7 downward, so that the slide rail 7 drives the limiting pressure plate 8 and the pressure strip plate 9 to descend. Since the limiting pressure plate 8 is lower than the pressure strip plate 9, the pressure strip plate 9 makes contact with the packaging cardboard first, and the telescopic motor 6 continues to output, so that the connecting block 10 compresses the spring 12, and the elastic force of the spring 12 is used to support the limiting pressure plate 8 and press the packaging cardboard. During the process, the pressure strip plate 9 continues to descend, and the pressure strip plate 9 is used to squeeze the packaging cardboard for indentation. After the pressure strip is completed, the telescopic motor 6 can be used to output in the reverse direction to pull the slide rail 7 upward, so that the limiting pressure plate 8 and the pressure strip plate 9 move upward, and the packaging cardboard can be removed. Before performing the layering operation, the device can also start the drive motor 17, and use the drive motor 17 to drive the screw rod 16 to rotate, so that the screw rod 16 drives the slider 18 to move, and the slider 18 drives the layering plate 9 to move, thereby adjusting the position of the layering plate 9 and changing the indentation position.

[0030] It is worth noting that the entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
