Description

Technical Field

[0001] This utility model relates to an industrial paperboard forming production line equipment, and more particularly to a folding forming machine for continuous processing of packaging boxes. Background Technology

[0002] With the widespread application of membrane products in various modes of transportation, especially the rapidly increasing number of small motor vehicles, there is a growing demand for large-scale production and logistics of these products. Typically, membrane rolls are quite heavy and require packaging before entering the logistics process to reduce the risk of damage. In addition to outer plastic film protection, they also need to be boxed and sealed to meet stacking requirements during logistics and prevent accidental rolling damage.

[0003] However, the packaging boxes used for transporting roll-of-film products are typically quite large. Previously, cardboard sheets were pre-cut and crimped, then manually folded before being stapled at multiple points to create the packaging boxes for packing products. This method was not only inefficient but also resulted in inconsistent box forming, occasionally leading to situations where packaged products could not be filled. Summary of the Invention

[0004] The purpose of this invention is to propose a folding forming machine for continuous processing of packaging boxes, thereby solving the problems of efficiency and quality improvement in the batch production of packaging boxes.

[0005] The technical solution of this utility model to achieve the above-mentioned objectives is a folding forming machine for continuous processing of packaging boxes, which is designed for pre-cutting and creasing of cardboard flat sheets. It includes a support platform, a molding punch, a folding unit, and an assembly unit. The support platform has a pair of first folding stops in the middle corresponding to the width of the box bottom surface. The molding punch is suspended at the top of the support platform and presses down on the middle of the cardboard flat sheet under control. The folding mechanism has a set of identical folding components at each end corresponding to the length of the packaging box. Each folding component consists of a pair of first folding push rods that fold the wing plate inwards and a second folding push rod that folds the outer plate upwards and adheres to and covers the wing plate. The assembly unit is adjustable in position and is used to staple the overlapping part of the outer plate and the wing plate.

[0006] Furthermore, the spacing between the pair of said first folding stops is adjustable.

[0007] Furthermore, each of the first folding plate push rods is provided with a pusher plate that is parallel to the side wall of the packaging box. The pusher plate is driven to flip from bottom to top, contacting and pushing the wing plate to fold; the pusher plate is driven to flip from top to bottom, withdrawing from between the wing plate and the outer plate.

[0008] Furthermore, the second folding plate push rod is provided with a pusher head with a flat side wall. The pusher head is driven to lift and push the outer plate to fold towards the wing plate.

[0009] Furthermore, the mounting element is an enlarged version of the stapler, which is suspended and mounted. In the downward suspended state, the bottom plate of the stapler is pressed against the inner side of the wing plate, and the staple outlet of the stapler is driven from the outer side of the outer plate towards the bottom plate.

[0010] Furthermore, the pusher piece in the first folding pusher and the pusher head in the second folding pusher are both provided with rounded corners that guide the sliding of the corresponding part of the cardboard flat sheet.

[0011] The cardboard box forming machine of this utility model has the following technical effects and advantages: by utilizing the sequential coordination of the stop bar, the molding punch, and the folding plate mechanism, continuous folding forming from cardboard flat sheet to box is realized. Combined with the use of the packaging unit to solidify the box, the forming efficiency of the box is greatly improved and the consistency of the finished product is higher, which is conducive to maintaining the smooth flow of film roll production and logistics. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of a preferred embodiment of the cardboard sealing and forming machine of this utility model. Detailed Implementation

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master, and thus to make a clearer definition of the protection scope of this utility model.

[0014] like Figure 1 As shown in the figure, this utility model is a folding and forming machine for continuous processing of packaging boxes. It is mainly used for pre-cut and creasing paperboard flat sheets 8, which are continuously folded into open boxes. As can be seen from the figure, the folding and forming machine includes a support platform 1, a molding punch 2, a folding unit, and an assembly unit. The support platform 1 is provided with a pair of first folding stops 11 in the middle of the middle of the box bottom width, while the molding punch 2 is suspended at the top of the support platform 1 and presses down on the middle 81 of the paperboard flat sheet 8 under control. In this way, the first folding stops and the molding punch complete the first fold of the paperboard flat sheet. The above-mentioned folding mechanism is provided with a set of identical folding components 3 at each end of the packaging box along the length direction. Each folding component consists of a pair of first folding push rods 31 that fold the wing plate inward and a second folding push rod 32 that folds the outer plate upward and fits the shielding wing plate. In this way, the second and third folds of the paperboard flat sheet are completed successively, and the initial shaping of the shorter side wall of the box is completed. The assembly unit is adjustable in position and used for staple-like fixing of the overlapping part of the outer panel and the wing panel. Here, both the top of the assembly unit and the molding hammer are externally connected to a crane and driven for lifting and positioning.

[0015] It should be noted that lifting control via a hoisting mechanism combined with sensors and other auxiliary components is a well-known operation in the field of science. Furthermore, given the known height of the hoisting rod from the support platform, the amplitude and positioning of the lifting control are easily achieved; therefore, illustrations and descriptions are omitted. Similarly, the loading and unloading conveying devices and pushing and straightening mechanisms associated with this forming machine as part of the production line are also omitted from illustrations and descriptions. This box-sealing forming machine is specifically designed for continuously folding and binding flat sheets of cardboard that have accurately entered the processing station.

[0016] In the preferred embodiment illustrated, the support platform is further provided with a guide groove, allowing the spacing between a pair of first-fold stop rods mounted therein to be adjusted and positioned within a limited range to meet the specifications of different sealing products. This can be achieved by a long screw passing through the guide groove from the bottom of the support platform and connecting to the first-fold stop rod. Loosening the long screw allows for displacement adjustment along the guide groove, while tightening the long screw fixes the first-fold stop rod.

[0017] More specifically, each first folding push rod 31 is equipped with a pusher piece 311 that is parallel to the side wall of the packaging box. Each pusher piece is pivotally connected to the surface of the support platform via a connecting shaft and is driven to flip from bottom to top, contacting and pushing the wing plate to fold; the pusher piece is driven to flip from top to bottom and withdraw from between the wing plate and the outer plate. In the initial state, the pusher pieces are shown as the leftmost and rightmost ones in the figure. In this way, when the cardboard sheet is pressed down into the support platform by the molding hammer, it will not interfere with the first fold, and the side plates 82 of the larger surface area on both sides of the cardboard sheet, together with the wing plates 83 at their respective ends, will fold upwards accordingly. When the folding mechanism is in operation, the pusher piece is shown as one of the ones on the left side of the figure, which flips inwards under the upward push drive of the attached telescopic pressure rod 5. The drive cylinder of the telescopic pressure rod can be set at the bottom of the support platform and passes through the preset strip groove of the support platform to connect with the pusher piece. It can be understood that when the telescopic pressure rod retracts and resets, the pusher piece is also pulled and reset accordingly.

[0018] The aforementioned second folding plate push rod 32 is equipped with a push head 321 with a flat sidewall. This push head is driven to lift and push the outer plate to fold towards the wing plate. In the initial state, the push head is embedded in the surface of the support plate platform, so it does not interfere with the first fold. Only after both wing plates have been folded are they driven to lift upward, thereby pushing the outer plate 84 to flip. From the processing sequence, the aforementioned first folding plate push rod does not immediately reset the push plate after completing the wing plate folding, but keeps the wing plate in a stable initial positioning state; when the outer plate flips open and can limit the wing plate's rebound, the push plate can then be flipped to reset.

[0019] The aforementioned mounting element is an enlarged version of the stapler 4, which is suspended and attached. In the downward-suspended state, the base plate 41 of the stapler is pressed against the inner side of the wing plate, and the staple outlet 42 of the stapler drives the staples from the outer side of the outer plate towards the base plate. As shown in the figure, the stapler is formed with a binding groove for fitting and overlapping the outer plate and the wing plate. In actual use, the binding groove can be used to position the stapled part.

[0020] In addition to the above, as can be seen in the preferred embodiment illustrated, both the pusher piece 311 in the first folding pusher and the pusher head 321 in the second folding pusher are provided with rounded corners that guide the sliding of the corresponding parts of the cardboard sheet. This effectively prevents sharp parts from scratching the relevant parts of the cardboard sheet, maintains the integrity of the carton's appearance, and helps to increase the smoothness of folding and forming and processing efficiency.

[0021] In summary, the above description of the folding forming machine of this utility model demonstrates its substantial features and advancements: by utilizing the sequential coordination of the stop bar, the molding punch, and the folding mechanism, continuous folding forming from cardboard flat sheets to packaging boxes is achieved. Combined with the use of packaging unit-cured packaging boxes, the forming efficiency of packaging boxes is greatly improved, and the consistency of finished products is higher, which is conducive to maintaining smooth flow from film roll production to logistics.

[0022] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
