Description

Technical Field

[0001] The utility model belongs to the technical field of paper box forming, and in particular relates to a paper box forming machine. Background Art

[0002] A carton forming machine is a device that forms a flat carton through various operating steps to eventually form a three-dimensional carton. The conventional operating steps require that the flat carton be first adsorbed or grabbed by a suction or vacuum device, placed in the forming area, and the predetermined folding operation is completed within the set specifications of the machine.

[0003] However, due to the material of the paper box, it is easy to deviate during the adsorption or grabbing process, which causes the set value to be unable to effectively drive the machine to complete the precise folding action, which in turn causes the paper box to be damaged. Therefore, a forming machine is designed in combination with a visual locator to position the flat paper shell after adsorption, achieve precise folding, and avoid damage to the finished product.

[0022] The utility model realizes adsorption of the transmitted flat paper box by using the adsorption back plate 3, so that it is placed vertically, and then drives the folding plate 15 to slowly insert the flat paper box, while the guide inclined plate 14 is also slowly inserted to expand a part of the flat paper box in advance, thereby reducing the pressure generated by the flat paper box when it is pushed by the folding plate 15; then when the folding plate 15 rotates to open the left and right sides of the flat paper box, the conversion and forming of the flat paper box to the three-dimensional paper box can be completed, and the folding plate 15 is movably set, so that it can adapt to the forming of paper boxes of multiple specifications and lengths; not only that, the utility model also adds a visual locator 4, so that the visual locator 4 can capture and locate the placement of flat paper boxes of different specifications, thereby achieving more accurate forming.

[0023] Example 2

[0024] according to Figures 1 to 5 The forming machine shown is suitable for paper boxes of multiple specifications, which is mainly used to open the flat paper boxes after folding and pasting, and cooperate with the later forming; it includes a frame 1, which is used to undertake all the electronic mechanical equipment in the device and to carry out the opening work of the flat paper boxes. The rear side of the inner wall of the frame 1 is provided with a mounting frame 2, and the lower front side of the mounting frame 2 is connected to an adsorption back plate 3 for adsorbing the flat paper boxes transmitted by the conveyor belt. The flat paper boxes are irregular in shape from top to bottom. After unfolding from the upper and lower sides, the flat paper boxes can be opened and formed into a three-dimensional paper box.

[0025] In order to ensure that the flat paper box receives sufficient adsorption force and can be tightly attached to the adsorption back plate 3, while cooperating with the folding action, it is also necessary to avoid hard contact between the flat paper box and the adsorption back plate 3, which would damage the surface of the flat paper box. Therefore, a rubber layer 16 is provided on the front side of the adsorption back plate 3 to achieve soft contact with the flat paper box through soft materials. While avoiding damage, the friction of the rubber can also enhance the connection with the flat paper box. In addition, a plurality of adsorption holes 17 are provided on the rubber layer 16, so that the flat paper box can be firmly fixed on the front side of the adsorption back plate 3 through the air suction in the adsorption holes 17, so as to cooperate with the stable operation of the folding action.

[0026] Example 3

[0027] according to Figures 1 to 5 The forming machine for paper boxes of various specifications shown in the figure is different from the common folding steps. In this embodiment, a folding plate 15 is used to extend into the interior of a flat paper box, and then rotated and unfolded to support the inner wall of the flat paper box on both sides and unfold outward, and then the flat paper box is formed by hot pressing. Specifically, an auxiliary frame 5 is installed on the front side of the frame 1, and a guide rail 6 is provided on the top of the auxiliary frame 5. A first slider 7 and a second slider 8 are slidably provided on the guide rail 6, and the first slider 7 is located on the left side of the second slider 8; thereby, the forming of three-dimensional paper boxes of different lengths can be realized, and by installing the folding assembly 11 on the first slider 7 and the second slider 8, the folding assemblies 11 on both sides are driven to move inward or outward to adapt to different lengths of three-dimensional paper boxes.

[0028] The folding assembly 11 is connected to the first slider 7 and the second slider 8 via the first mounting seat 9 and the second mounting seat 10. It should be noted here that the first mounting seat 9 is directly mounted on the front side of the first slider 7, and the second mounting seat 10 is installed by extending the first slider 7 backward, that is, the second mounting seat 10 will span the entire guide rail 6 and the second slider 8 and be located on the rear side of the guide rail 6. The folding assembly 11 includes an electric push rod 12, an articulated seat 13, a guide inclined plate 14 and a folding plate 15. There are two electric push rods 12, which are respectively arranged on the first mounting seat 9 and the second mounting seat 10. The lower part of the electric push rod 12 is rotatably provided with an articulated seat 13, and the bottom of the articulated seat 13 is connected with a folding plate 15. Then, when the adsorption back plate 3 completes the adsorption of the flat paper box, the electric push rod 12 is driven to drive the articulated seat 13 and the folding plate 15 to move downward, so that they can be extended into the flat paper box. At the same time, the folding plate 15 is rotated to make it vertical and parallel to the wide side of the flat paper box, and then the electric push rod 12 is pushed to move the corresponding stroke on the guide rail 6 to realize the expansion limit of the three-dimensional paper box, so as to cooperate with the later hot pressing forming.

[0029] In order to prevent the folding plate 15 from being unable to open the flat paper box effectively due to the internal pressure of the flat paper box after entering and rotating in the flat paper box, a guide inclined plate 14 is provided between the folding plate 15 and the hinge seat 13, that is, when the electric push rod 12 is extended to drive the hinge seat 13 and the folding plate 15 to move downward, the guide inclined plate 14 will be slowly inserted into the flat paper box as the folding plate 15 is extended. Through the gradually expanding shape of the guide inclined plate 14, a part of the space of the flat paper box is slowly expanded in advance, thereby reducing the pressure generated by the flat paper box when being pushed by the folding plate 15.

[0030] In summary, after the adsorption back plate 3 completes the adsorption of the flat paper box, the folding plate 15 will move downward and extend into the flat paper box, that is, the folding plate 15 and the flat paper box need to be on almost the same horizontal line, and the present embodiment specially sets the guide inclined plate 14 to be opposite, so the guide inclined plate 14 on the second mounting seat 10 needs to be moved backward, that is, the second mounting seat 10 is installed to extend the first slider 7 backward.

[0031] Example 4

[0032] According to the content of Example 3, the conveyor belt will transfer the folded flat paper box backward to be adsorbed by the adsorbed back plate 3, and then the electric push rod 12 will stretch and drive its lower folding plate 15 to move into the flat paper box. During this period, affected by the guide inclined plate 14, the flat paper box will slowly open a part, and then the electric push rod 12 will move on the guide rail 6 until the folding plate 15 rotates to support the left and right inner walls of the three-dimensional paper box to cooperate with the subsequent hot pressing molding.

[0033] From now on, in order to further accurately realize the operation of the folding component 11 for flat cartons of different specifications, this embodiment is also provided with a visual locator 4 above the frame 1, located in front of all components, for positioning the electric push rod 12 in advance, quickly and accurately completing the opening of the flat cartons, and forming a three-dimensional carton. The visual locator 4 uses a device with image visual detection technology, which can analyze the position of the target object in real time through non-contact measurement. After combining with the utility model, that is, when the flat carton moves into the device via the conveyor belt, the visual locator 4 will capture the flat carton, and then obtain the final positioning point of the flat carton on the adsorption back plate 3. At this time, the two points on the front of the flat carton are pointed out, representing the length of the flat carton, and the calculation result is issued to make the slider move to the corresponding position on the slide rail, so that the folding plate 15 has reached the inner wall edge of the flat carton when it moves downward into the flat carton, without the need for excessive manual adjustments in the later stage. It is simple and fast and suitable for opening flat carton boxes of various sizes to complete the forming of a three-dimensional carton.
