Description

Technical Field

[0001] This utility model relates to the technical field of thin box opening equipment, specifically, to a box opening machine for foil thin boxes. Background Technology

[0002] Foil thin boxes are boxes used to hold foil sheets, which are typically 0.06mm to 0.2mm thick. For example, a box may contain 24 foil sheets, and the internal height of the thin box generally does not exceed 5mm. A box-opening machine is a device that unfolds a folded cardboard box blank into a box shape.

[0003] In existing technologies, the opening of tongue-and-groove boxes is generally accomplished using a push cylinder. However, foil-sheet boxes are mostly folded boxes, and the sealing strip of a folded box is in two sections. It is not possible to achieve precise folding of the two sections of the sealing strip by simply pushing. Therefore, manual opening is currently the preferred method for this type of box. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a box opening machine for foil thin boxes, which solves the technical problem that two-section sealed boxes are not easy to open in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a box-opening machine for foil thin boxes, comprising: The frame is equipped with an opening space, allowing the folded cardboard box blank to unfold after entering the opening space; The suction cup is mounted on the frame and is located at the bottom of the opening space. The suction cup can rise to adsorb the folded paper box blank and then descend into the opening space. There are several folding ear pushers, all of which are slidably disposed on the frame. Each of the several folding ear pushers corresponds one-to-one with a number of folding ears of the cardboard box. The folding ear pusher is used to push the folding ear to fold, and the folding ear can press against the section of the sealing sheet near the box body. The first pusher is lifted and installed on the frame. The first pusher is located on one side of the box opening space. The first pusher can rise and push the part of the sealing sheet away from the box to fold upward. The second pusher is lifted and installed on the frame. The second pusher is located on one side of the opening space and on the other side of the first pusher. The second pusher can rise and push the sealing plate near the box body upward after the folding ear pusher slides away from the folding ear.

[0006] For example, in at least one embodiment of the present invention, a foil thin box opening machine further includes: A limiting member is slidably mounted on the frame. The limiting member is located at the front end of the box opening. The limiting member can slide into the box and support the top of the box. The limiting member can prevent the sealing sheet from folding under the limiting member.

[0007] For example, in at least one embodiment of the present invention, a foil thin box opening machine further includes: A positioning plate is installed on this frame. A push plate is installed on the frame, and the opening space is formed between the push plate and the positioning plate. The push plate is used to push the side of the folded carton blank to unfold.

[0008] For example, in at least one embodiment of the present invention, a box-opening machine for foil thin boxes includes a pusher plate comprising: A limiting section is provided on the frame, and the limiting section is rectangular; A guide push section is located at the top of the limiting section. The top of the guide push section is longer than the bottom of the positioning plate in a vertical distance, so that the side of the folded carton blank can gradually unfold under the action of the guide push section.

[0009] For example, in at least one embodiment of the present invention, a foil thin box opening machine further includes: A storage box mechanism is installed on the frame. The storage box mechanism is used to store folded paper box blanks. The storage box mechanism is located above the opening space, and the bottom of the storage box mechanism is connected to the opening space so that the suction cup can rise and adsorb the folded paper box blank at the bottom of the storage box mechanism.

[0010] For example, in at least one embodiment of the present invention, a box-opening machine for foil thin boxes includes a box storage mechanism comprising: A support frame is provided on the top of the frame body, and there is a gap between the top surface of the support frame and the top of the frame body. The positioning plate and the push plate are both located within the gap. A plurality of limiting plates are provided on the support frame, and the plurality of limiting plates form a storage space, and the plurality of limiting plates respectively abut against the side of the folded cardboard box blank located in the storage space.

[0011] For example, in a foil-type box opening machine provided in at least one embodiment of the present invention, the suction cup can be lowered away from the opening space so that the paper box on the suction cup can leave the suction cup from the side.

[0012] For example, in a foil thin box opening machine provided in at least one embodiment of the present invention, the edges of the first pusher and the second pusher are both rounded.

[0013] For example, in at least one embodiment of the present invention, a box-opening machine for foil thin boxes further includes a driving mechanism, which includes: A first linear pusher is mounted on the frame, and the suction cup is connected to the telescopic end of the first linear pusher. A second linear jacking component is provided on the frame, and the limiting component is connected to the telescopic end of the second linear jacking component; The third linear jacking member is installed on the frame, and the first jacking member is connected to the telescopic end of the third linear jacking member; A fourth linear jacking member is installed on the frame, and the second jacking member is connected to the telescopic end of the fourth linear jacking member; There are several fifth linear jacking components, all of which are installed on the frame. Each of the fifth linear jacking components is connected to the folding lug jacking component in a one-to-one correspondence.

[0014] For example, in a foil thin box opening machine provided in at least one embodiment of the present invention, the third linear pusher and the fourth linear pusher operate alternately.

[0015] The beneficial effects of this utility model are as follows: In this invention, for a thin foil box with a two-section sealing sheet, the folding lugs are folded by pushing the lugs, and the first and second pushers push the two sections of the sealing sheet respectively, thus completing the opening of the two-section sealing sheet. When the folding lugs are pushed, they also press against the section of the sealing sheet closest to the box body. The first pusher first pushes the section of the sealing sheet away from the box body to fold, and then, after the folding lugs slide away from the lugs, the second pusher pushes the section of the sealing sheet closest to the box body to fold, thus achieving sequential folding of the two-section sealing sheet.

[0024] like Figures 1-3 The diagram illustrates a foil-type thin box opening machine according to one embodiment of the present invention, including a frame 100, suction cups 200, folding ear pushers 300, a first pusher 400, and a second pusher 500. The frame 100 is a frame structure welded from metal profiles, providing support for the entire box opening machine. The frame 100 has an opening space 110, the shape of which can be rectangular. The suction cups 200 can be made of rubber, possessing good elasticity and adsorption force, and their shape is preferably circular. Several suction cups 200 can be provided, forming a planar adsorption surface for the folded paper box blank. Alternatively, a single suction cup 200 can be used, its size selected according to the size of the folded paper box blank, allowing one suction cup 200 to stably adsorb the surface of the folded paper box blank. Regardless of whether a single suction cup 200 or several suction cups 200 are used, the suction cups 200 are all connected. Furthermore, the suction cup 200 is connected to the telescopic end of the first linear pusher 910 via a connecting frame. The connecting frame and the telescopic end of the first linear pusher 910 can be bolted together for easy replacement of the suction cup 200. The suction cup 200 has a hollow internal structure. When the suction cup 200 rises and contacts the folded cardboard box blank, a vacuum pump or negative pressure generator creates a negative pressure inside the suction cup 200, thereby adsorbing the folded cardboard box blank. Then, under the action of the first linear pusher 910, it descends into the opening space 110.

[0025] The first linear pusher 910 is preferably a cylinder, which is installed at the bottom of the frame 100 and connected to an air source through an air pipe. By controlling the on / off state and pressure of the air source, the suction cup 200 can be lifted and lowered.

[0026] The folding lug pusher 300 can be made of metal or plastic, and its shape is determined by the shape and position of the folding lug 02 of the cardboard box. It can be a rectangular block. The folding lug pusher 300 slides on the frame 100 via a fifth linear pusher 950. The fifth linear pusher 950 is preferably a cylinder, and its telescopic end is connected to the folding lug pusher 300. By controlling the telescopic extension of the cylinder, the sliding of the folding lug pusher 300 is achieved. The number of folding lug pushers 300 is set according to the number of folding lug 02 of the foil thin box. Generally, a foil thin box has 4 folding lug 02, so 4 folding lug pushers 300 are set, each corresponding to one of the 4 folding lug 02 of the cardboard box.

[0027] The first pusher 400 is a rectangular plate structure. It is connected to the telescopic end of the third linear pusher 930 via a connecting seat. The connecting seat and the first pusher 400 are connected by welding or bolts. The third linear pusher 930 is preferably a cylinder, installed on one side of the frame 100, and connected to an air source via an air pipe. The lifting and lowering of the first pusher 400 is achieved by controlling the air source. The first pusher 400 is located on one side of the opening space 110. Its length and height are determined according to the size of the foil-thin box sealing sheet 03. The length is less than the height of the section of the sealing sheet 03 away from the box body 01, ensuring that the first pusher 400 can push the section of the sealing sheet 03 away from the box body 01 upwards under the action of the third linear pusher 930.

[0028] The second pusher 500 is similar in structure to the first pusher 400, also being a rectangular plate. The second pusher 500 is connected to the telescopic end of the fourth linear pusher 940 via a connecting seat. The fourth linear pusher 940 is also a cylinder, installed on the side of the frame 100 adjacent to the first pusher 400, and its lifting and lowering are controlled by connecting to an air source via an air pipe. The second pusher 500 is located on one side of the first pusher 400, and its position must ensure that after the folding lug pusher 300 slides away from the folding lug 02, it can accurately push the end of the sealing plate near the box 01 to fold upwards.

[0029] Working principle: First, the folded carton blank is placed above the carton opener. The suction cup 200 rises under the action of the first linear pusher 910, adsorbing the folded carton blank, and then descends into the opening space 110. At this time, several folding ear pushers 300, pushed by the fifth linear pusher 950, slide along the guide rail, pushing the folding ears 02 of the carton, causing the folding ears 02 to fold and press against the section of the sealing plate 03 near the box body 01. Next, the first pusher 400 rises under the action of the third linear pusher 930, pushing the section of the sealing plate 03 away from the box body 01 to fold upwards. Afterwards, the folding ear pushers 300 slide away from the folding ears 02 under the action of the fifth linear pusher 950, and the second pusher 500 rises under the action of the fourth linear pusher 940, pushing the end of the sealing plate near the box body 01 to fold upwards, thus completing the opening process of the foil-sheet thin carton.

[0030] For a thin foil box with a two-section sealing sheet 03, the folding lug 02 is folded by pushing the folding lug 300, and the first pusher 400 and the second pusher 500 push the two sections of the sealing sheet 03 respectively, thus completing the opening of the two-section sealing sheet 03. When the folding lug 02 is pushed by the folding lug 300, it can also press on the section of the sealing sheet 03 closest to the box body 01. The first pusher 400 first pushes the section of the sealing sheet 03 away from the box body 01 to fold. Then, after the folding lug 300 slides away from the folding lug 02, the second pusher 500 pushes the section of the sealing sheet 03 closest to the box body 01 to fold, thus realizing the sequential folding of the two-section sealing sheet 03.

[0031] Furthermore, to prevent the head of the section of the sealing sheet 03 furthest from the box body 01 from failing to enter the box body 01 due to its height exceeding the top of the box body 01 when the second pusher 500 pushes the sealing sheet 03 closer to the box body 01 for folding, the foil thin box opening machine also includes a limiting member 600. The limiting member 600 is preferably a flat rectangular block, with a length slightly smaller than the width of the opening in the box body 01. The limiting member 600 is mounted on the telescopic end of the second linear pusher 920 via a connecting seat. The telescopic movement of the second linear pusher 920 allows the limiting member 600 to slide on the frame 100. The second linear pusher 920 is mounted on the frame 100 and is preferably a cylinder.

[0032] During the opening process of the foil-lined box, after the first pusher 400 pushes the section of the sealing sheet 03 away from the box body 01 to fold upwards, before the second pusher 500 prepares to push the section of the sealing sheet 03 closer to the box body 01 to fold, the limiting member 600, under the action of the second linear pusher 920, slides into the box body 01. The limiting member 600 supports the top of the box body 01, at which point the head of the section of the sealing sheet 03 away from the box body 01 is restricted below the limiting member 600. When the second pusher 500 rises to push the section of the sealing sheet 03 closer to the box body 01 to fold, due to the obstruction of the limiting member 600, the sealing sheet 03 can only fold below the limiting member 600. Thus, after the second pusher 500 folds the section of the sealing sheet 03 closer to the box body 01 into place, the section of the sealing sheet 03 away from the box body 01 enters the box body 01. This avoids the problem that the head of the section of the sealing sheet 03 away from the box body 01 cannot enter the box body 01 because its height exceeds the top of the box body 01. After the sealing sheet 03 is folded, the limiting member 600 slides out of the box body 01 under the action of the second linear pusher 920, and then the second pusher 500 descends away from the sealing plate, thus completing the opening of the entire folded carton blank.

[0033] Furthermore, the opening space 110 is formed by a positioning plate 710 and a push plate 720. The positioning plate 710 is rectangular and is firmly fixed to the frame 100 by bolts or welding to ensure that it will not shift during the opening process. The positioning plate 710 can abut against one long side of the folded carton blank, thereby serving as a reference for positioning. The push plate 720 is preferably a plate structure with a right-angled trapezoidal cross-section. The right-angled side of the push plate 720 is fixed to the frame 100 by welding or bolting. The opening space 110 is formed between the push plate 720 and the positioning plate 710. The push plate 720 not only supports the folded carton blank, but also pushes the folded carton blank to unfold as it descends under the suction of the suction cup 200. The specific working principle is that one end of the side of the folded carton blank abuts against the positioning plate 710, and the other end rests on the inclined side of the push plate 720. As the height decreases, the vertical distance between the surface of the push plate 720 and the surface of the positioning plate 710 decreases, so the folded carton blank will unfold during the descent.

[0034] The positioning plate 710 ensures the accurate position of the folded carton blank within the opening space 110, allowing the push plate 720 to push the side of the carton open under the action of the opposing force formed by the push plate 720 during the downward movement of the folded carton blank. This ensures the consistency of the opening position and guarantees that each foil thin box can be accurately opened in the predetermined manner, avoiding the inability to cooperate with the first pusher 400, the second pusher 500, the folding ear pusher 300, and other structures after opening due to inaccurate positioning.

[0035] Furthermore, the push plate 720 includes a limiting section 721 and a guide pushing section 722. The limiting section 721 is rectangular and preferably has a height not less than the height of the cardboard box. The limiting section 721 is fixed to the frame 100 by bolts or welding. The limiting section 721 works in conjunction with the positioning plate 710 to ensure that the cardboard box is aligned with the opening space 110, and also provides a mounting base for the guide pushing section 722. The guide pushing section 722 is fixed to the top of the limiting section 721 by welding, and the side of the guide pushing section 722 near the positioning plate 710 is smoothly connected to the side of the limiting section 721 near the positioning plate 710. Preferably, the guide pushing section 722 and the limiting section 721 are integrally formed, and the entire push plate 720 is manufactured through processes such as forging and machining. The guide and push section 722 has a right-angled trapezoidal structure, with the top being longer than the bottom in vertical distance from the positioning plate 710, forming an inclined guide surface. This inclined guide surface provides support for the folded carton blank and also uses the reaction force to push the folded carton blank open.

[0036] After the folded carton blank enters the opening space 110, the inclined guide surface of the guide push section 722 first contacts the side of the carton blank. As the folded carton blank moves downward, the contact point between the guide surface and the side of the carton gradually moves downward. Under the action of the guide surface, the side of the carton is subjected to a gradually increasing component force, which causes the side of the carton to gradually unfold. This method can guide the side of the carton to unfold in a predetermined manner.

[0037] refer to Figure 2 and Figure 3 In some embodiments, to achieve continuous box feeding, a foil thin box opening machine also includes a box storage mechanism 800. The frame of the box storage mechanism 800 is typically constructed from metal profiles, forming a rectangular frame structure with a certain height and width. Its height is determined based on the number of folded cardboard box blanks stored at one time and the height of the folded cardboard box blanks. Inside the frame, a cavity is formed for storing the folded cardboard box blanks. The inner wall of the cavity can be made of smooth sheet material, such as stainless steel, and is installed on the frame by welding or bolting to reduce friction between the cardboard box and the inner wall, facilitating smooth sliding of the cardboard box. The bottom of the cavity is open, communicating with the opening space 110. The opening size is slightly larger than the size of the folded cardboard box blank, ensuring that the cardboard box can pass through smoothly.

[0038] Furthermore, the storage box mechanism 800 includes a support frame 810 and a limiting plate 820. The support frame 810 is a rectangular frame with several support legs at its bottom. The support legs are fixed to the frame 100 by welding or bolting and are distributed around the opening space 110. The support legs form a gap between the support frame 810 and the surface of the frame 100. The positioning plate 710 and the push plate 720 are located within this gap. The folding pusher 300 and the limiting member 600 can both pass through this gap and contact the cardboard box in the opening space 110.

[0039] Based on the shape and size of the foil-sheet thin box, several limiting plates 820 are installed on the support frame 810, typically four, corresponding to the four sides of the folded cardboard box blank. These limiting plates 820 are fixed to the top of the support frame 810 by welding or bolting to provide height extension, facilitating the placement of stacked folded cardboard box blanks. The main function of the limiting plates 820 is to limit and guide the cardboard box blanks. When the cardboard box blanks are placed into the storage space, the limiting plates 820 restrict the lateral movement of the cardboard box blanks, ensuring they are neatly arranged. During the box retrieval process by the suction cup 200, the limiting plates 820 ensure the stability of the cardboard box blank's position, preventing it from shaking or tipping over within the storage mechanism 800, and ensuring that the suction cup 200 can accurately pick up the bottom cardboard box blank.

[0040] Furthermore, to achieve continuous unfolding of the folded carton blank, the suction cup 200 is connected to the telescopic end of the first linear pusher 910. The first linear pusher 910 needs to have sufficient stroke to ensure that the suction cup 200 can descend to a position far away from the carton space 110. This descent stroke needs to be determined based on the overall layout of the equipment and the space required for the carton to detach from the suction cup 200 from the side. Generally, the suction cup 200 needs to descend a certain distance below the bottom of the carton space 110, such as 100-200mm, to ensure that the carton has enough space to detach from the suction cup 200 from the side.

[0041] After completing the opening operation of a foil-sheet box, the suction cup 200 begins to descend under the action of the first linear pusher 910. As the suction cup 200 descends, it gradually moves away from the box space 110 and descends to a preset position. At this point, the suction cup 200 stops adsorbing, and the operator or other unloading mechanism removes the opened cardboard box from the bottom, making it easier for the suction cup 200 to continue rising to adsorb another folded cardboard box blank.

[0042] Furthermore, to prevent damage to the sealing plate caused by the pushing action when the first pusher 400 and the second pusher 500 come into contact with the sealing plate, both the first pusher 400 and the second pusher 500 have rounded edges.

[0043] Furthermore, the third linear jacking member 930 and the fourth linear jacking member 940 operate alternately. If the third linear jacking member 930 and the fourth linear jacking member 940 are in the form of cylinders, their alternating operation can be achieved using a single air pump, simplifying the control system. Similarly, using an electric cylinder can also simplify the control program.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
