Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box shaping auxiliary device. Background Technology

[0002] Different beverages have different packaging sizes and appearances. Therefore, when a factory develops a new beverage, it needs to produce corresponding packaging boxes. The development process for these packaging boxes involves prototyping, small-batch trial production, and mass production.

[0003] Tetra Pak is a series of packaging products developed by the Swedish company Tetra Pak for liquid foods. Tetra Pak's "brick-shaped" and "pillow-shaped" cartons are common paper packaging for milk and beverages. Among them, such as... Figures 1-2 As shown, the Tetra Pak type of packaging box 7 has folding wings 71.

[0004] In existing technology, when the packaging box 7 is in the small-batch trial production stage, glue needs to be manually applied to the glue dots at the packaging ends of the packaging box 7. Then, the operator needs to apply pressure to the folding flap 71 to make the glue adhere. However, during this process, fluctuations in the force applied by hand cause uneven glue penetration, resulting in weak adhesion under light pressure and material deformation under heavy pressure. There is no quantitative feedback, and the operator cannot determine whether the actual pressure has reached the glue curing threshold. The work efficiency is low, requiring repeated adjustments to the pressing position, which can easily cause glue dot misalignment. Since there may be many debugging issues in the small-batch trial production stage, the structure of the mass-produced packaging box 7 may differ from the initial trial production structure. Using an automated packaging mechanism in the small-batch trial production stage would be too costly. If the packaging mechanism is not suitable for the final mass-produced packaging box 7, it will be idle, resulting in wasted resources. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging box shaping auxiliary device to meet the needs of small-batch physical sample production of packaging boxes, improve work efficiency, and reduce costs.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A packaging box shaping auxiliary device includes a box body with an opening at the top and a pressure plate that is slidably assembled inside the box body;

[0008] The box body has a first side plate and a second side plate that are disposed opposite to each other;

[0009] A pressure sensor is provided on the inner wall of the first side plate; a shaping cavity is formed between the pressure plate and the pressure sensor; the shaping cavity is used to shape the flaps of the packaging box;

[0010] The second side plate is provided with a screw for adjusting the distance between the pressure plate and the pressure sensor; the first end of the screw is rotatably connected to the pressure plate, and the second end is threaded to the second side plate and extends out of the box body. Through the cooperation of the box body, pressure plate, pressure sensor and screw, the shaping cavity can effectively apply pressure and shape the flaps of packaging boxes of different sizes.

[0011] Furthermore, the first side plate, the second side plate, and the pressure plate are arranged in parallel. This design allows the pressure plate to slide smoothly within the box, effectively shaping the folds of the packaging box.

[0015] Furthermore, a counterweight is provided at the bottom of the box. This design lowers the box's center of gravity, preventing accidental tipping.

[0016] Furthermore, the packaging box shaping auxiliary device also includes a controller and an early warning device;

[0017] The early warning device and the pressure sensor are respectively electrically connected to the controller;

[0018] The controller is adapted to trigger an overpressure warning device when the pressure value sensed by the pressure sensor exceeds a certain threshold. This approach aims to alert workers to apply excessive pressure to the packaging box.

[0019] Furthermore, the shaping threshold is 5N to 20N. This method is used to prevent excessive pressure on the packaging box.

[0020] Furthermore, the packaging box shaping auxiliary device also includes a display device for displaying the pressure value sensed by the pressure sensor;

[0021] The display device is connected to the pressure sensor; the display device can be a pressure gauge or a monitor. This design allows staff to view the sensed pressure value.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] A packaging box shaping aid is provided for shaping the flaps 71 of a packaging box 7. In this embodiment, the packaging box shaping aid is applied after the flaps 71 are coated with adhesive to apply pressure to the flaps 71 so that the flaps 71 are effectively adhered to the packaging box 7.

[0041] like Figures 3-5 As shown, the packaging box shaping auxiliary device includes a box body 1, a pressure plate 2, and a pressure sensor 3. The box body 1 is open at the top and sealed at the bottom. The box body 1 has a first side plate 11 and a second side plate 12 arranged opposite to each other. The pressure sensor 3 is disposed on the inner wall of the first side plate 11. The pressure plate 2 is slidably assembled inside the box body 1, and a shaping cavity with an open top is formed between the pressure plate 2 and the pressure sensor 3. The shaping cavity is used to shape the flaps 71 of the packaging box 7. A screw 4 is provided on the second side plate 12. The first end of the screw 4 is rotatably connected to the pressure plate 2, and the second end of the screw 4 is threadedly connected to the second side plate 12 and extends to the outside of the box body 1. The screw 4 is used to adjust the distance between the pressure plate 2 and the pressure sensor 3.

[0042] When the operator rotates the screw 4, the pressure plate 2 is slidably assembled inside the box 1, and the screw 4 is rotatably connected to the pressure plate 2, so the pressure plate 2 moves along the axial direction of the screw 4.

[0043] This invention utilizes the cooperation of the box body 1, pressure plate 2, pressure sensor 3, and screw 4 to enable the shaping cavity to effectively apply pressure and shape the flaps 71 of packaging boxes 7 of different specifications.

[0044] In this embodiment, the box 1 is a rectangular structure, including four side plates and a bottom plate.

[0045] Furthermore, the first side plate 11, the second side plate 12, and the pressure plate 2 are arranged in parallel to allow the pressure plate 2 to slide smoothly within the box body 1, thereby effectively shaping the folds 71 ​​of the packaging box 7. The axis of the screw 4 is perpendicular to the pressure plate 2, and the screw 4 is located in the middle of the pressure plate 2.

[0046] Furthermore, a guide groove 13 is provided on the inner wall of the box body 1. The pressure plate 2 is provided with a sliding protrusion that cooperates with the guide groove 13. The guide groove 13 includes, but is not limited to, rectangular grooves, dovetail grooves, etc.

[0047] In this embodiment, guide grooves 13 are formed on the bottom plate of the housing 1. There are two guide grooves 13. The length direction of the guide grooves 13 is parallel to the axial direction of the screw 4.

[0048] Furthermore, the second side plate 12 and the pressure plate 2 are connected by a guide post 5 and a guide sleeve 6. The guide sleeve 6 passes through the second side plate 12. The guide post 5 is placed inside the guide sleeve 6, and one end of it is fixedly connected to the pressure plate 2. The axis of the guide post 5 is parallel to the axis of the screw 4. The cooperation of the guide post 5 and the guide sleeve 6 effectively guides and limits the pressure plate 2.

[0049] In this embodiment, there are two guide posts 5 and two guide sleeves 6, which correspond one-to-one.

[0050] Furthermore, to prevent the packaging box shaping aid from tipping over, such as... Figure 6 As shown, a counterweight 14 is provided at the bottom of the box 1 to lower the center of gravity of the box 1.

[0051] Furthermore, to facilitate the rotation of the screw 4, a handle 41 is provided at the second end of the screw 4. The handle 41 is located outside the housing 1.

[0052] Furthermore, in order to facilitate observation of the glue penetration near the glue dots on the packaging box 7, both the box body 1 and the pressure plate 2 are made of transparent material.

[0053] In some embodiments, such as Figure 7 As shown, a removable transparent film 21 may be provided on the side of the pressure plate 2 near the first side plate 11. Specifically, one side of the transparent film 21 is provided with self-adhesive. The transparent film 21 is attached to the pressure plate 2 by self-adhesive. When glue from the packaging box 7 overflows onto the pressure plate 2, the transparent film 21 can be replaced to ensure the cleanliness of the pressure plate 2, thereby preventing glue residue on the pressure plate 2 from contaminating the next packaging box 7 to be shaped.

[0054] In some embodiments, such as Figure 8 As shown, a detachable pull-out plate 22 may be provided on the side of the pressure plate 2 near the first side plate 11. Specifically, a slot is provided on the side of the pressure plate 2 near the first side plate 11, and the pull-out plate 22 is inserted into the slot. The pull-out plate 22 is made of transparent material. When the glue from the packaging box 7 overflows onto the pressure plate 2, the cleanliness of the pressure plate 2 can be ensured by replacing the transparent film 21.

[0055] Furthermore, the detection end of the pressure sensor 3 is located on the side of the pressure sensor 3 away from the first side plate 11. In some embodiments, the detection end of the pressure sensor 3 is provided with a connecting plate, which is arranged parallel to the second side plate 12.

[0056] Furthermore, the packaging box shaping auxiliary device also includes a display device (not shown in the attached diagram). The display device is connected to the pressure sensor 3 and is used to display the pressure value sensed by the pressure sensor 3. The display device can be a pressure gauge or a monitor. Operators can determine whether to continue rotating the screw 4 based on the sensed pressure value displayed on the display device. The display device can be installed on the outer wall of the box body 1.

[0057] In this embodiment, the working principle of the packaging box shaping auxiliary device is as follows:

[0058] After applying glue to the glue dots on the folding 71, the staff inserted the packaging box 7 into the shaping cavity (e.g. Figure 3 (as shown);

[0059] Rotate screw 4 so that the flaps 71 at both ends of the packaging box 7 are pressed by pressure sensor 3 and pressure plate 2 respectively; when the sensing pressure value displayed by the display device is 5N to 20N, stop rotating screw 4. At this time, the distance between pressure sensor 3 and pressure plate 2 remains unchanged; after maintaining the pressure for 3 to 5 seconds, remove the packaging box 7.

[0060] Place each of the packaging boxes 7 into the molding cavity, press them together for 3 to 5 seconds, and then remove them.

[0061] This embodiment utilizes the combination of the box body, pressure plate, pressure sensor, and screw to enable the shaping cavity to effectively apply pressure and shape the flaps of packaging boxes of different sizes.

[0062] Example 2

[0063] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the packaging box shaping auxiliary device also includes a controller and an early warning device.

[0064] The warning device and pressure sensor 3 are electrically connected to the controller. The controller is adapted to control the warning device to issue an overpressure warning when the pressure value sensed by the pressure sensor 3 exceeds a predetermined threshold.

[0065] In this embodiment, the shaping threshold is 5N to 20N.

[0066] In this embodiment, the warning device includes, but is not limited to, a buzzer, a photoelectric alarm, etc. The warning device and controller can be installed on the housing 1.

[0067] Furthermore, the controller is also adapted to control the early warning device to issue a safety warning when the pressure value sensed by the pressure sensor 3 is greater than 0N and less than or equal to the set threshold.

[0068] This embodiment uses a controller, an early warning device, and a pressure sensor to prompt workers to rotate the screw to apply pressure to the packaging box or to stop applying pressure.

[0069] The above provides a detailed description of two embodiments of this utility model. However, the description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent protection scope of this utility model.
