[0002] During the forming process of the paper box, it is necessary to manually fold it side by side along the creases. Generally, for a paper box without a cover, it is necessary to fold the ears first, then fold one side, and finally fold the other side. After folding the paper box, the ears and one side are manually fixed and placed on the nailing mechanism for fixation. The whole process requires manual multi-step completion, the box folding efficiency is low, the folded paper box is not flat enough, the precision is low, and the quality is poor. At the same time, there are certain safety hazards in the process of manual nailing and fixing. Summary of the invention

In order to achieve the above functions, the above technical problems of the present invention are mainly solved by the following technical solutions:

The pushing mechanism is used to push the folded and fixed paper box out through the pushing channel.

[0007] This paper box folding forming machine, by respectively arranging a lifting mechanism and a pushing mechanism on the upper and lower sides of the folding mold, the upper and lower lifting mechanisms and the pushing mechanism cooperate with each other to improve the folding efficiency and quality of the paper box; by respectively arranging nailing mechanisms on the left and right sides of the folding mold, the folded paper box can be immediately fixed by the nailing mechanism; by arranging a pushing mechanism on the rear side of the folding mold and cooperating with a pushing channel, the folded and fixed paper box can be immediately pushed out.

[0008] This paper box folding and forming machine has a simple structure and ingenious design. The bottom plate of the folded paper box is straight, the folding efficiency is high, and the quality is good. The folded paper box can be fixed immediately and then pushed out immediately. The entire folding, fixing and pushing out action is fully automatic, orderly and continuous, which improves the production efficiency of the entire process, ensures the regularity and quality of the paper box, and reduces safety hazards.

The inclined folding plate two is fixedly connected to the left and right sides with vertical folding plates three that are perpendicular to the inclined folding plate two. The top of the vertical folding plate three is fixedly connected with an inclined folding plate three that is inclined outward and upward. The two vertical folding plates one and the two vertical folding plates two form a rectangular mold cavity. The two inclined folding plates one and the inclined folding plates two form a trumpet mouth that is inclined outward and upward. The four inclined folding plates three form a "V"-shaped mouth that is inclined outward and upward on the trumpet mouth. The vertical folding plate two is higher than the vertical folding plate one.

[0014] The ear folding assemblies are directly arranged on the front and rear folding plate assemblies, so that the whole mechanism is more compact, simple and has strong integrity. At the same time, the ear folding assemblies are directly arranged on the front and rear folding plate assemblies. The height of the ear folding assemblies is naturally higher than that of the front and rear folding plate assemblies, and the height of the front and rear folding plate assemblies is higher than that of the left and right folding plate assemblies, so that the order of folding the cardboard plates from top to bottom is folding the ears, the front and rear plates, and the left and right plates. The paper box is naturally formed from top to bottom. The different heights of the ear folding assemblies, the front and rear folding plate assemblies, and the left and right folding plate assemblies are cleverly used to determine the order of folding, thereby avoiding interference between the folding of the left and right plates when folding the ears, and there is no need to set ear folding action components and components specifically for preventing interference with other side panels when folding the ears. There is no need for matching related components, so that the structure of the whole machine is simpler.

[0015] The left and right folding plate components are composed of a vertical folding plate 1 and an inclined folding plate 1, and the front and rear folding plate components are composed of a vertical folding plate 2 and an inclined folding plate 2, so that when the cardboard is pressed in by the lifting cylinder, the cardboard is first inclined and folded and then vertically folded from the upper inclined folding plate 1 to the lower vertical folding plate pair in the left and right directions, and the setting of the inclined folding plate 1 has a certain buffering transition effect on the folding of the cardboard in the left and right directions, and the cardboard is first inclined and then vertically folded from the upper inclined folding plate 2 to the lower vertical folding plate 2 in the front and rear directions, and the setting of the inclined folding plate 2 has a certain buffering transition effect on the folding of the folding plate in the front and rear directions.

[0016] Since the height of the vertical folding plate 2 is higher than that of the vertical folding plate 1, and the vertical folding plate 3 is located on the inclined folding plate 2, the cardboard is folded from top to bottom according to the different heights of the folding ear assembly, the front and rear folding plate assembly, and the left and right folding plate assembly. The folding ears on both sides of the front and rear plates of the cardboard are folded in the left and right directions, and then the front and rear plates of the cardboard are folded in the front and rear directions. At this time, the folding ears are also turned over with the direction of the front and rear plates. Finally, the left and right plates are folded in the front and rear directions. In this way, during the folding process, the folding ears automatically overlap with the two sides of the front and rear plates, and the next step is to perform the nailing process, which completely restores the entire manual folding process.

[0019] The vertical folding plate 1 is composed of at least two vertical folding plate units 1 arranged side by side, and the inclined folding plate 1 is composed of at least two inclined folding plate units 1 arranged side by side. The vertical folding plate 1 and the inclined folding plate 1 of different lengths can be achieved by adjusting the gap between the at least two vertical folding plate units 1 and the at least two inclined folding plate units 1, and the distance between the front and rear at least two vertical folding plate 1 and the inclined folding plate 1 can also be adjusted by adjusting bolts; similarly, the vertical folding plate 2 is composed of at least two vertical folding plate units 2 arranged side by side, and the inclined folding plate 2 is composed of at least two inclined folding plate units 2 arranged side by side.

[0044] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0045] like Figure 1-6 As shown, the paper box folding forming machine in this embodiment includes a frame 1, a conveying mechanism 2 is horizontally arranged on the upper rear side of the frame 1, a lifting mechanism 3 is installed on the conveying mechanism 2, a suction cup 11 is arranged at the bottom of the lifting mechanism 3, a discharge bin 4 is arranged on the front right side of the frame 1, a folding mold 5 is arranged on the front left side of the frame 1, and the lifting mechanism 3 can be located directly above the discharge bin 4 or the folding mold 5 under the transportation of the conveying mechanism 2, nailing mechanisms are respectively arranged on the left and right sides of the folding mold 5, a pushing mechanism 10 is arranged on the rear lower side of the folding mold 5, a lifting mechanism 9 is arranged directly below the folding mold 5, a suction cup 12 is arranged on the top of the lifting mechanism 9, and a pushing channel 6 is arranged at the front of the lifting mechanism 9.

[0046] In this paper box folding forming machine, the lifting mechanism 3 and the pushing mechanism 9 are respectively located above and below the folding mold 5. The lifting mechanism 3 absorbs the upper surface of the paperboard through the suction cup 11, and the pushing mechanism 9 absorbs the lower surface of the paperboard through the suction cup 2 12, so that when the paperboard with creases is folded, the bottom plate 8.4 can be kept straight and fixed in all directions. The bottom plate 8.4 is straight and fixed, which makes it more convenient to fold the paperboard, and the folding is more regular, thereby improving the folding accuracy and quality, and ensuring the efficiency of folding paper boxes.

[0047] The left and right sides of the folding mold 5 are respectively provided with nailing mechanisms, so that the folded paper box can be immediately nailed by the nailing mechanism and fixed by the cooperation of the lifting mechanism, so that the folded paper box is finally fixed. The pushing mechanism 10 is set to push the folded and fixed paper box through the pushing channel 6.

[0048] This paper box folding forming machine, by respectively arranging a lifting mechanism 3 and a pushing mechanism 9 on the upper and lower sides of the folding mold 5, the upper and lower lifting mechanisms 3 and the pushing mechanism 9 cooperate with each other to improve the folding efficiency and quality of the paper box; by respectively arranging nailing mechanisms on the left and right sides of the folding mold 5, the folded paper box can be immediately fixed by the nailing mechanism; by arranging a pushing mechanism 10 on the rear side of the folding mold 5 and cooperating with the pushing channel, the folded and fixed paper box can be immediately pushed out.

[0049] This paper box folding and forming machine has a simple structure and ingenious design. The folded paper box bottom plate 8.4 is straight, the folding efficiency is high, and the quality is good. The folded paper box can be fixed immediately and pushed out immediately after being fixed. The entire folding, fixing, and pushing out action is automatically, orderly and continuously operated, which improves the production efficiency of the entire process, ensures the regularity and quality of the paper box 8, and reduces safety hazards.

[0050] The lifting mechanism 3 is a lifting cylinder, the pushing mechanism 10 is a pushing cylinder, and the ejecting mechanism 9 is a ejecting cylinder.

[0051] The conveying mechanism 2 includes a linear guide rail assembly installed on the crossbeam on the rear side of the frame 1, a lifting cylinder is fixed on the linear guide rail assembly, a suction cup 11 is fixed at the bottom of the lifting block 3.1 of the lifting cylinder, and sensors are respectively installed at the starting end and the tail end of the linear guide rail assembly.

[0052] The linear guide assembly comprises two linear guide mechanisms arranged in parallel on the crossbeam. Two sliders in the two linear guide mechanisms are fixedly connected with a connecting plate 2.1, and a lifting cylinder is fixedly installed on the connecting plate 2.1.

[0053] The linear guide assembly uses two parallel linear guide mechanisms, which makes the lifting cylinder move left and right more stable and stable, and can carry a larger load.

[0054] The folding mold 5 includes left and right folding plate components, front and rear folding plate components, and ear folding components are arranged on the front and rear folding plate components. The front and rear folding plate components are slightly higher than the left and right folding plate components. The left and right folding plate components include vertical folding plates 5.1 respectively arranged in the left and right directions, and the vertical folding plate 5.1 is fixedly connected with an inclined folding plate 5.2 inclined outwardly and upwardly; the front and rear folding plate components include vertical folding plates 5.3 respectively arranged in the front and rear directions, and the vertical folding plate 5.3 is fixedly connected with an inclined folding plate 5.4 inclined outwardly and upwardly; the ear folding components include vertical folding plates 5.5, The inclined folding plate three 5.6 and the inclined folding plate two 5.4 are fixedly connected on the left and right sides with vertical folding plates three 5.5 perpendicular to the inclined folding plate two 5.4, and the top of the vertical folding plate three 5.5 is fixedly connected with an inclined folding plate three 5.6 inclined outwardly and upwardly. The two vertical folding plates one 5.1 and the two vertical folding plates two 5.3 form a rectangular mold cavity, and the two inclined folding plates one 5.2 and the inclined folding plates two 5.4 form a trumpet mouth inclined outwardly and upwardly. The four inclined folding plates three 5.6 form a "V"-shaped mouth inclined outwardly and upwardly on the trumpet mouth, and the vertical folding plate two 5.3 is higher than the vertical folding plate one 5.1.

[0055] The ear folding assemblies are directly arranged on the front and rear folding plate assemblies, so that the whole mechanism is more compact, simple and has strong integrity. At the same time, the ear folding assemblies are directly arranged on the front and rear folding plate assemblies. The height of the ear folding assemblies is naturally higher than that of the front and rear folding plate assemblies, and the height of the front and rear folding plate assemblies is higher than that of the left and right folding plate assemblies, so that the order of folding the cardboard plates from top to bottom is the folding of the ear 8.1, the front and rear plates 8.2, and the left and right plates 8.3. From top to bottom, the paper box 8 is naturally formed. The different heights of the ear folding assemblies, the front and rear folding plate assemblies, and the left and right folding plate assemblies are cleverly used to determine the folding sequence, thereby avoiding interference between the folding of the left and right plates 8.3 when the ear 8.1 is folded, and there is no need to set the ear folding 8.1 action component and its special component for preventing interference with other side panels when folding the ear 8.1. There is no need for matching related components, so that the structure of the whole machine is simpler.

[0056] The left and right folding plate components are composed of a vertical folding plate 5.1 and an inclined folding plate 5.2, and the front and rear folding plate components are composed of a vertical folding plate 5.3 and an inclined folding plate 5.4, so that when the cardboard is pressed into the lifting cylinder, the left and right directions from the upper inclined folding plate 5.2 to the lower vertical folding plate 5.1 are first tilted and folded, and then folded vertically at 90 degrees. The setting of the inclined folding plate 5.2 has a certain buffering transition effect on the folding of the cardboard in the left and right directions, and the front and rear directions from the upper inclined folding plate 5.4 to the lower vertical folding plate 5.3 are first tilted and then folded vertically at 90 degrees. The setting of the inclined folding plate 2 5.4 has a certain buffering transition effect on the folding of the folding plate in the front-to-back direction. The vertical folding plate 3 5.5 and the inclined folding plate 3 5.6 arranged on the inclined folding plate 2 5.4 first tilt from the upper inclined folding plate 3 5.6 to the lower vertical folding plate folding ear 8.1 and then fold vertically at 90 degrees. The setting of the inclined folding plate 3 5.6 has a certain buffering transition effect on the 90-degree vertical folding of the folding ear 8.1 of the cardboard in the left and right directions, thereby reducing the impact of the folding of the cardboard on the cardboard, and further reducing the damage of the cardboard due to the folding impact that affects the strength and quality of the folded paper box.

[0057] Since the height of the second vertical folding plate 5.3 is higher than the first vertical folding plate 5.1, and the third vertical folding plate 5.5 is located on the second inclined folding plate 5.4, the folding ears 8.1 on both sides of the front and rear plates 8.2 of the cardboard are folded 90 degrees in the left and right directions according to the different heights of the folding ear components, the front and rear folding plate components, and the left and right folding plate components from top to bottom, and then the front and rear plates 8.2 of the cardboard are folded 90 degrees in the front and rear directions. At this time, the folding ears 8.1 are also turned 90 degrees along with the front and rear plates 8.2. Finally, the left and right plates 8.2 are folded 90 degrees in the front and rear directions. In this way, during the folding process, the folding ears 8.1 automatically overlap with the two sides of the front and rear plates 8.2, and wait for the next step of the nailing process, which completely restores the entire manual folding process.

[0058] This folding mold 5 is provided with front and rear folding plate assemblies and left and right folding plate assemblies, and ear folding assemblies are directly provided on the front and rear folding plate assemblies to realize the folding of the ear 8.1. According to the different heights of the ear folding assembly, the front and rear folding plate assembly, and the left and right folding plate assembly, the ear 8.1, the front and rear panels 8.2, and the left and right panels 8.3 are folded in sequence.

[0059] The vertical folding plate 5.1 is composed of at least two vertical folding plate units 5.1.1 arranged side by side, the inclined folding plate 5.2 is composed of at least two inclined folding plate units 5.2.1 arranged side by side, the vertical folding plate 5.3 is composed of at least two vertical folding plate units 5.3.1 arranged side by side, and the inclined folding plate 5.4 is composed of at least two inclined folding plate units 5.4.1 arranged side by side. Each vertical folding plate unit 1 5.1.1 and vertical folding plate unit 2 5.3.1 is respectively provided with an adjusting bolt 5.7. The vertical folding plate 3 5.5 is triangular, and the vertical folding plate unit 1 5.1 is provided with nailing holes in cooperation with the nailing mechanism 9.

[0060] The vertical folding plate 5.1 is composed of at least two vertical folding plate units 5.1.1 arranged side by side, and the inclined folding plate 5.2 is composed of at least two inclined folding plate units 5.2.1 arranged side by side. The vertical folding plate 5.1 and the inclined folding plate 5.2 of different lengths can be realized by adjusting the gap between the at least two vertical folding plate units 5.1.1 and the at least two inclined folding plate units 5.2.1. The distance between the front and rear at least two vertical folding plates 5.1 and the inclined folding plate 5.2 can also be adjusted by adjusting the bolts; similarly, the vertical folding plate 5.3 is composed of at least two vertical folding plate units 5.3.1. The inclined folding plate 2 5.4 is composed of at least two inclined folding plate units 2 5.4.1 arranged side by side. The vertical folding plate 2 5.3 and the inclined folding plate 2 5.4 of different lengths can be achieved by adjusting the gap between at least two vertical folding plate units 2 5.3.1 and at least two inclined folding plate units 2 5.4.1. The distance between at least two vertical folding plates 2 5.3 and the inclined folding plates 2 5.4 on the left and right can also be adjusted by adjusting the bolts, thereby realizing the adjustment of the folding size of paper boxes of different lengths and widths, and having a wider range of applications. The nailing holes on the vertical folding plate unit 1 5.1.1 are convenient for the nailing mechanism to pass through when nailing.

[0061] The two outer sides of the two nailing mechanisms are respectively connected through a synchronous chain transmission mechanism, the synchronous chain transmission mechanism is connected to a reduction chain transmission mechanism, and the reduction chain transmission mechanism is connected to a motor.

[0062] The two nailing mechanisms are connected on both sides by a synchronous chain transmission mechanism, thereby ensuring the synchronization of the two nailing mechanisms, thereby achieving synchronous nailing on the left and right sides.

[0063] The left and right side surfaces of the lifting block 3.1 are provided with concave grooves for fixing the nails to bend in cooperation with the nail holes, and the pushing channel 6 is a 90-degree bent plate similar to a "U".

[0064] The concave grooves provided on the lifting block 3.1 facilitate the nailing mechanism to automatically bend the nails after driving them into the paper box, so that the nails can completely fix the folded paper box.

[0065] Stacked cardboards are placed in the discharge bin 4. Positioning blocks 4.1 are respectively arranged on the front and rear inner walls of the discharge bin 4. The positioning blocks 4.1 cooperate with the cardboards for positioning. A finished product bin is arranged at the lower part of the rear side of the push-out channel 6.

[0066] Positioning blocks 4.1 are respectively arranged on the front and rear inner walls of the discharge bin 4 for positioning the cardboards placed in the discharge bin 4. Multiple layers of cardboards are stacked in the discharge bin 4, which saves time and improves feeding efficiency.

[0067] The control mechanism 7 is also included. The control mechanism 7 is connected to the conveying mechanism 2, the lifting mechanism 3, the pushing mechanism 10, and the material pushing mechanism 9 respectively. The suction cup 11 and the suction cup 2 12 are connected to the negative pressure gas source respectively.

[0068] The control mechanism 7 is used to connect and control the coordinated and orderly operation of the conveying mechanism 2 , the lifting mechanism 3 , the pushing mechanism 10 , and the ejecting mechanism 9 .

[0069] The working principle and process of the present invention.

[0070] like Figure 1-6 As shown, the main working process of this paper box folding forming machine.

[0071] First, adjust the size of the folding mold 5 according to the length and width of the paper box to be folded, and adjust the length of the vertical folding plate 5.1 and the inclined folding plate 5.2 by adjusting the gap between the vertical folding plate unit 1 5.1.1 and the inclined folding plate unit 1 arranged side by side, or adjust the distance between the two vertical folding plates 1 5.1 and the two inclined folding plates 1 5.2 by adjusting the bolts to adjust the front and back lengths; adjust the length of the vertical folding plate 2 5.3 and the inclined folding plate 2 5.4 by adjusting the gap between the vertical folding plate unit 2 5.3.1 and the inclined folding plate unit 2 5.4.1, or adjust the distance between the two vertical folding plates 2 5.3 and the two inclined folding plates 2 5.4 by adjusting the bolts to adjust the left and right lengths, so as to adapt to the length and width of the paper box.

[0072] After adjusting the length and width of the rectangular cavity of the folding die 5, the cardboard with creases is stacked and placed in the discharge bin 4. In the initial state, the lifting cylinder is located at the right end of the conveying mechanism 2. At this time, the lifting cylinder is located directly above the discharge bin 4, and the control mechanism 7 is started. The control mechanism 7 starts the lifting cylinder to descend and sucks the origami with creases directly below through the suction cup 11 at the bottom of the lifting block. The lifting cylinder rises, and then the conveying mechanism 2 is started by the control mechanism 7 to move the lifting cylinder horizontally to the right end. At this time, the lifting cylinder is located directly above the folding die 5. The control mechanism 7 controls the lifting cylinder to descend and press the cardboard with creases into the folding die 5. At the same time, the ejecting mechanism 9 rises upward, and the suction cup 2 at the top of the ejecting mechanism 9 sucks the bottom surface of the cardboard. At this time, the cardboard with creases is pressed flat from top to bottom without shaking, so that the cardboard remains flat and fixed, which is more convenient to fold, and the folding accuracy of the cardboard is guaranteed.

[0073] The paper box with creases is folded from top to bottom along the folding die 5. First, the folding ear 8.1 of the paperboard is automatically folded 90 degrees through the uppermost folding ear assembly, and then the front and rear boards 8.2 of the paperboard are folded 90 degrees through the front and rear folding plate assemblies. Finally, the left and right boards 8.3 of the paperboard are folded 90 degrees through the left and right folding plate assemblies. The paper box is automatically and completely formed in the process of the lifting cylinder pressing the paperboard from top to bottom. At this time, the nailing mechanism located in the folding die 5 nails both sides of the paper box in the length direction. Since the lifting block 3.1 of the lifting cylinder is provided with a concave point groove for bending the nail, the nail driven into the paper box by the nailing mechanism can be bent and fixed smoothly. The folding ear 8.1 and the left and right boards 8.3 are fixed. The control mechanism 7 controls the pushing cylinder to push the folded and fixed paper box forward into the pushing channel 6, and enters the discharge bin through the pushing channel 6.

[0074] This paper box folding and forming machine realizes automatic material suction, automatic conveying, automatic material pressing, automatic material pushing, automatic folding, automatic stapling and automatic pushing out in sequence. It has good folding efficiency and the folded paper boxes are flat and of good quality.

[0075] In this paper box folding forming machine, the lifting mechanism 3 and the pushing mechanism 9 are respectively located above and below the folding mold 5. The lifting mechanism 3 and the pushing mechanism 9 simultaneously suck and press the bottom plate 8.4 of the paperboard from top to bottom. The lifting mechanism 3 sucks the top of the paperboard through the suction cup 11, and the pushing mechanism 9 sucks the bottom of the paperboard through the suction cup 2 12. It can ensure that when the paperboard with creases is folded, the bottom plate 8.4 can be kept straight and fixed in all directions. The bottom plate 8.4 is straight and fixed, which makes it more convenient to fold the paperboard, and the folding is more regular, thereby improving the folding accuracy and quality, and ensuring the efficiency of folding paper boxes.

[0076] In this paper box folding forming machine, nailing mechanisms are respectively arranged on the left and right sides of the folding mold 5, so that the folded paper box can be immediately nailed by the nailing mechanism and fixed by the cooperation of the lifting mechanism 3, so that the folded paper box is finally fixed. The pushing mechanism 10 is arranged to push the folded and fixed paper box through the pushing channel 6.

[0077] This paper box folding and forming machine has a simple structure and ingenious design. The folded paper box bottom plate 8.4 is straight and folded more smoothly with high precision, good quality and high efficiency. The folded paper box can be fixed immediately and pushed out immediately after being fixed. The entire folding, fixing and pushing out action is fully automatic, orderly and continuous, which improves the production efficiency of the entire process, ensures the regularity and quality of the paper box 8 and has high safety.

[0078] The folding mold in this paper box folding forming machine has a simple structure, ingenious design and strong integrity. The folding sequence of the folding ears, front and rear panels, and left and right panels is limited by the different heights of the folding ears, front and rear folding plate components, and left and right folding plate components, thereby preventing the front and rear panels, and left and right panels from interfering with the folding ears when folding the ears. No additional supporting and related components are required, thereby simplifying the structure of the paper box forming machine corresponding to the folding mold.

[0079] The folding mold in the paper box folding forming machine has inclined folding plates in the left and right folding plate components, the front and rear folding plate components, and the folding ear components, which has a certain buffering transition effect on the folding of the folding plates, reduces the damage caused by the impact of folding on the cardboard, and improves the quality and strength of the paper box.

[0080] In this paper box folding forming machine, the front and rear folding plate components, left and right folding plate components, and folding ear components in the folding mold 5 are respectively designed with at least two pieces, so that the lengths of the front and rear folding plate components, left and right folding plate components, and folding ears 8.1 themselves can be adjusted. At the same time, the distance between the two folding plate components can also be adjusted, thereby realizing the adjustment of the folding plate modules for paper boxes of different lengths and widths, increasing the scope of application and practicality.

[0081] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
