Description

Technical Field

[0001] This application relates to the field of packaging boxes, specifically to a packaging box support and a molding process for packaging boxes. Background Technology

[0002] Packaging boxes are widely used in all aspects of people's production and life. In order to improve the strength of packaging boxes, our company has applied for a base that can make the packaging box have higher strength in the patent "A Packaging Box Base with Flip Buckle" (application number 202220900421.X). This base can effectively fasten to the upper edge of the material board, improve the stress capacity of the material board, increase the stability of the product, and can also be used as a handle, thus improving the product's performance.

[0003] As the product is promoted and used, its weight is relatively heavy due to the large number of plastic parts. With the standardization of the market, many markets have set limits on the weight of packaging. If the weight of the packaging box exceeds the limit, it will not be allowed to enter the market for sale.

[0004] To better meet market demands while ensuring the strength of the packaging boxes, our company has further optimized the product and applied for an invention patent for "a support structure for stacked packaging boxes" (application number 202311160877.2). This invention uses plastic only in the support structure, which greatly reduces the weight of the finished packaging box and effectively prevents the weight of the packaging box from exceeding the limit.

[0005] However, in actual use, although the above-mentioned support structure meets market demand, its positioning during assembly is difficult, and it can only be assembled manually by workers. It is difficult to match with automated equipment, which greatly increases the assembly cost of the product. Summary of the Invention

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] like Figure 1-4 As shown, a packaging box support includes a crossbar 100 and two uprights 200 symmetrically arranged on the left and right sides of the crossbar 100; the uprights 200 are rotatable about the connection position between the crossbar 100 and the uprights 200; the crossbar 100 and the uprights 200 are respectively provided with positioning clips 105 and positioning holes 207 for mutual positioning.

[0042] The use of matching positioning clips and holes can better limit the rotation angle of the column when it rotates, preventing the angle between the column and the crossbar from changing before subsequent operations. This ensures the stability of the product during assembly and improves the assembly effect and efficiency.

[0043] The crossbar 100 consists of a strip 101, a slot block 102 located at the center of the front of the strip 101 and forming a slot with the strip 101, and column heads 103 symmetrically arranged on the left and right sides of the front of the strip; the number of positioning clips 105 is two and they are symmetrically arranged on the left and right sides of the front of the strip 101, with the two positioning clips 105 located below the two column heads 103 respectively.

[0044] The positioning clip is sloping, which allows the column to be lifted directly by its slope during rotation, ultimately allowing the positioning clip to directly enter the positioning hole. After the positioning clip is engaged in the positioning hole, its vertical wall effectively prevents the positioning clip from disengaging from the positioning hole. This eliminates the need to manually lift the column during assembly to engage the positioning clip, further reducing assembly difficulty, simplifying the assembly process, and ensuring the secure fixation between the positioning clip and the positioning hole, preventing them from disengaging during assembly.

[0045] The column head 103 is cylindrical, and a set of locking blocks 104 are symmetrically arranged on the upper side wall of the column head 103.

[0046] When setting up the locking blocks, the line connecting the two locking blocks is preferably at a 45° angle to the horizontal plane. This ensures that the uprights and crossbars do not detach from each other when they are kept horizontal or vertical.

[0047] The column 200 consists of a column body 201, a column head hole 206 that runs through the column body 201 from front to back and whose shape matches the combined structure of the column head 103 and the locking block 104, a side plate locking slot 202 vertically disposed on the column body 201 on the side opposite to the column head hole 206, and at least one side plate clip 203 disposed on the side wall of the side plate locking slot 202; the positioning hole 207 runs through the column body 201 from front to back and is located below the column head hole 206; the top of the column body 201 is provided with a positioning head 208, and the bottom of the column body 201 is provided with a limiting groove 209 whose position matches the positioning head 208.

[0048] The thickness of the column head hole and the distance between the bottom of the column head and the bottom surface of the locking block are the same, which ensures the firmness of the fit between the column and the crossbar.

[0049] In addition, since the product is made of plastic, it has a certain degree of deformation capability, which can effectively prevent the product from cracking or components from detaching during use due to the guidance of the slope structure.

[0050] Several clamping strips 205 are also provided on the side wall of the side plate slot 202; the clamping strips 205 are arranged opposite to the side plate clips 203; the front ends of the clamping strips 205 and the side plate clips 203 are both sloping.

[0051] The clamping strip makes it easier for the clips on the side panel to be pushed into the side panel clips, further improving the accuracy of assembly and ensuring the assembly effect.

[0052] The clamping bar and the front end of the side plate clip are designed with a slope, which reduces the difficulty of inserting the side plate and further reduces the assembly difficulty during automatic assembly.

[0053] Example 2

[0054] The only difference between this embodiment and embodiment 1 is that the front of the strip 101 is also provided with two mutually symmetrical guide inclined plates 106, which are respectively arranged on the left and right sides of the slot block 102; the two guide inclined plates 106 gradually approach each other from bottom to top.

[0055] Setting up guide ramps can reduce the alignment requirements of manual labor or equipment during product assembly. When the sheet metal and the bracket are mated, even if there is a deviation in the horizontal alignment between them, the corresponding structure of the sheet metal can smoothly enter the slot of the bracket, effectively improving the assembly efficiency and effect of the product.

[0056] Example 3

[0057] The only difference between this embodiment and embodiment 1 or 2 is that a positioning block 204 is also provided on the side wall of the side plate slot 202; the side of the positioning block 204 facing the opening direction of the side plate slot 202 is circular or triangular.

[0058] The positioning blocks can effectively cooperate with the positioning holes on the sheet metal, allowing the product to quickly and automatically adjust its position during assembly. This enables the side panel clips to accurately cooperate with the clips on the sheet metal, effectively improving assembly efficiency and effectiveness.

[0059] Example 4

[0060] like Figure 5-8 As shown, a packaging box forming process uses the packaging box bracket described in Example 3;

[0061] The specific process steps are as follows:

[0062] (1) Produce packaging box brackets and boards of the corresponding sizes according to demand;

[0063] The plate material must have at least a base plate, a front plate connected to the front of the base plate, a rear plate connected to the rear of the base plate, and side plates connected to the left and right sides of the base plate respectively.

[0064] The design of the board material needs to be adjusted according to the packaging box support. However, both board material design and production are mature technologies in the industry. Those skilled in the art can complete the design and production of the board material according to the assembly requirements of the packaging box. The biggest difference between different boards material is mainly the size and the requirements for fitting details. The specific structure of the board material is existing technology and will not be described in detail here.

[0065] A cover plate is also connected to the front of the rear plate of the board; the cover plate is provided with a through hole that matches the positioning head on the column; the left and right sides of the front plate and the rear plate are respectively provided with a latch corresponding to the clip on the side plate of the column; the left and right sides of the front plate and the rear plate are respectively provided with a positioning opening that corresponds to the shape and position of the positioning hole on the column.

[0066] The sheet material can be cardboard, plastic sheet, acrylic sheet, glass sheet, etc.

[0067] (2) Combine a horizontal bar with two symmetrical vertical columns to form a complete packaging box support;

[0068] (3) Insert the crossbars of the two packaging box brackets into the outer sides of the two side panels from the left and right sides respectively;

[0069] To improve positioning accuracy, each of the two side plates of the sheet metal is designed with a trapezoidal mating head that matches the shape of the slot and the guide ramp. This greatly reduces the difficulty of positioning, allowing the product assembly to better meet the needs of machine assembly and promoting the realization of mechanized and automated assembly.

[0070] (4) Rotate the two uprights on the packaging box bracket until the positioning clips are engaged in the positioning holes;

[0071] It is necessary to ensure that the side panels are located in front of the columns;

[0072] (5) Flip up the front panel and the back panel respectively;

[0073] (6) Flip up the two side panels respectively, so that the two sides of the front panel and the rear panel are inserted into the corresponding side panel slots of the column.

[0074] It is necessary to ensure that the side plate clips of the column engage with the clips on the front or rear plate respectively.

[0075] The positioning blocks on the column can effectively cooperate with the positioning holes on the plate, allowing the product to quickly and automatically adjust its position during assembly. This enables the side plate clips to accurately cooperate with the clips on the plate, effectively improving assembly efficiency and effectiveness.

[0076] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0077] Furthermore, the specific embodiments described above are exemplary.
