Description

Technical Field

[0001] This application relates to the technical field of folding box devices, and in particular, to an accurate box buckling mechanism for folding boxes and a folding box device. Background Art

[0002] The cardboard used in the folding box equipment goes through a series of technological processes such as feeding, transfer, downward pressing and forming, front and back flanging and folding of the box, left and right edge pressing of the box, left and right edge buckling, and transfer and discharging to complete the processing and production of the paper box. During the processing of the paper box, due to the certain plasticity of the cardboard itself, the requirement of parallelism needs to be ensured during the production of the cardboard.

[0003] In the existing cardboard folding box equipment, due to the non - meeting of the cardboard parallelism requirement and the inaccurate positioning of the paper box, there are usually two problems: First, due to the plasticity of the cardboard, in the process of downward pressing and forming, the parallelism of the cardboard is poor, so that the preset forming effect cannot be fully achieved. At the same time, the positioning difference and the insufficient relative position accuracy between each folding box station result in that in the subsequent left and right edge buckling process, due to the inclination of the paper box or the insufficient relative parallelism between the left and right edge pressing folding box mechanism and the previous process mechanism, a large number of paper boxes cannot be buckled in place. Second, when folding, flanging and buckling the box, due to the inaccurate positioning of the paper box and the insufficient relative parallelism between the folding box mechanisms, the end box buckling process in the folding box process often fails to buckle the box in place, and the operator needs to manually buckle the box a second time to complete the forming of the paper box, resulting in a low fully - automated rate of the folding box equipment and being unable to be directly connected to the automated packaging production line.

[0004] Therefore, it is necessary to design an accurate box buckling mechanism for folding boxes to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0029] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the products of this application are usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0031] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0032] According to a first aspect of the present invention, a precise box-closing mechanism for a folding box is provided. As Figures 1 to 8 shown, the precise box-closing mechanism for a folding box is used for a folding box device, which can precisely fold a paper box 5 and ensure the folding accuracy, thereby enabling the subsequent box-closing process to be accurately in place. The folding box device may include a main frame 1 and a flanging and folding box mechanism 2. Here, it should be noted that the number of the flanging and folding box mechanisms 2 can be multiple, for example, a front-back flanging and folding box structure, a left-right edge-pressing and folding box mechanism, and a left-right box-closing mechanism, etc. Since the flanging and folding box mechanism 2 is a mechanism in the prior art and is known to those skilled in the art, its installation method, usage process, and principle will not be elaborated here.

[0033] The precise box-closing mechanism for a folding box includes a leveling component 3 and a transfer and positioning component 4. In the following description, reference will be made to Figures 1 to 8 specifically describe the detailed structures of the leveling component 3 and the transfer and positioning component 4 of the precise box-closing mechanism for a folding box.

[0034] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, in the embodiment, the main frame 1 includes a first frame 101 and a second frame 102, and the first frame 101 is disposed on the upper part of the second frame 102. Specifically, the first frame 101 and the second frame 102 can divide the main frame 1 into an upper layer and a lower layer. The formed two-layer main frame 1 can facilitate the separate installation of the leveling component 3 and the transfer and positioning component 4. Furthermore, by adjusting the parallelism of the leveling component 3 (the flanging and folding box mechanism 2 is installed on the leveling component 3), the parallelism of the flanging and folding box mechanism 2 can be adjusted, ensuring the parallelism of the production of the paper box 5 and avoiding the box-closing not being in place due to inclination. Here, the paper box 5 can be made of cardboard in the process of pressing and forming. Since the precise box-closing mechanism for a folding box is used for the flanging and folding box processes, the pressing and forming process is not shown. In addition, those skilled in the art can know the pressing and forming process, and can also know the production process from cardboard to the paper box 5, which will not be elaborated here.

[0035] As Figure 1 , Figure 3 , Figure 4 ,Figure 5 and Figure 7 As shown in Figure 7 , in the embodiment, the leveling assembly 3 is adjustably disposed on the first frame 101. The leveling assembly 3 can be understood as a frame body for assisting the installation of the flanging and folding carton mechanism 2. This frame body can adjust the levelness with the first frame 101, thereby realizing the adjustment of the levelness of the flanging and folding carton mechanism 2 and ensuring the levelness during the production process. The transfer and positioning assembly 4 is disposed on the second frame 102. The transfer and positioning assembly 4 is used to carry the carton 5. At the same time, the transfer and positioning assembly 4 is slidably disposed on the second frame 102 for transporting the carton 5. The carton 5 formed in the press-forming process is transported to the lower part of the flanging and folding carton mechanism 2 through the transfer and positioning assembly 4, and then the processes of flanging and folding the carton are carried out. The leveling assembly 3 faces the transfer and positioning assembly 4 so that the flanging and folding carton mechanism 2 can face the carton 5 on the transfer and positioning assembly 4.

[0036] In summary, through the cooperation of the leveling assembly 3, the transfer and positioning assembly 4 and the main frame 1 formed into a two-layer structure, the precision snap-in carton mechanism for carton folding can individually adjust the parallelism of the flanging and folding carton mechanism 2, thereby enabling the flanging and folding carton mechanism 2 to have sufficient parallelism and relative position accuracy, ensuring the production accuracy of the carton 5 during debugging or production, and solving the problem that the carton 5 is not snapped in place due to inclination.

[0037] Preferably, as Figure 3 and Figure 4 As shown in Figure 4 , in the embodiment, the leveling assembly 3 may include an installation part 301 and support feet 302. The installation part 301 is used for the installation of the flanging and folding carton mechanism 2. The installation part 301 may be composed of multiple laterally arranged steel materials. The flanging and folding carton mechanism 2 is detachably disposed on the installation part 301. The flanging and folding carton mechanism 2 can be detachably installed on the laterally arranged steel materials by using fastening bolts. The installation position can be selected according to needs or the specifications of the produced carton 5, and no limitation is made here. In addition, those skilled in the art can select a correspondingly matching flanging and folding carton mechanism 2 according to the specifications of the produced carton 5, and disassembly and replacement can be achieved through fastening bolts. The number of the support feet 302 is multiple, and the multiple support feet 302 are circumferentially arranged on the installation part 301. In the embodiment, the number of the support feet 302 is four, and the four support feet 302 are respectively disposed at the four corners of the installation part 301. Each support foot 302 is adjustably connected to the first frame 101 through an adjustment member 303. In the embodiment, the adjustment member 303 may be a leveling bolt, and the leveling bolt can realize the quick installation of the support feet 302 while being able to adjust the levelness.

[0038] Preferably, as Figure 7As shown, in the embodiment, the transfer and positioning assembly 4 may include a moving part, a supporting part, and a positioning part. The moving part is disposed on the second frame 102. The positioning part is slidably disposed on the moving part through the supporting part. The moving part is used to move the paper box 5. The supporting part can support the paper box 5 and can adjust the height of the paper box 5. The positioning part can position the paper box 5.

[0039] Preferably, as Figure 7 shown, in the embodiment, the positioning part may include a bearing bottom plate 401, positioning baffles 402, and a proximity member 403. The bearing bottom plate 401 is used to bear the paper box 5. The positioning baffles 402 are disposed at both ends of the bearing bottom plate 401 and can limit the paper box 5 from both ends in the length direction of the bearing bottom plate 401 to prevent the paper box 5 from moving or coming out. The proximity member 403 is disposed at the bottom of the bearing bottom plate 401. The proximity member 403 can detect the parallelism state of the paper box 5 at this time and promptly inform the user of the paper box 5 that does not meet the parallelism requirement.

[0040] Preferably, as Figure 7 shown, the number of the positioning parts may be multiple. The multiple positioning parts are arranged in sequence end to end on the supporting part. In the embodiment, the number of the positioning parts may be two. The two positioning parts can respectively bear a paper box 5, so that the two paper boxes 5 located on the positioning parts can perform operations of different processes. For example, one performs front and back flanging, and the other continues to perform left and right edge pressing.

[0041] Preferably, as Figure 5 and Figure 6 shown, in the embodiment, side baffles 404 are further disposed on both sides of the transfer and positioning assembly 4. The two side baffles 404 and the two positioning baffles 402 surround the four sides of the paper box 5. In the embodiment, the paper box 5 may be formed in an approximate cuboid shape. The approximate cuboid paper box 5 may include four faces. The limitation of these four faces can be respectively realized by the two side baffles 404 and the two positioning baffles 402. A contact support 405 is disposed on the end face of the side baffle 404 facing the transfer and positioning assembly 4. The contact support 405 can be used for the lapping of the paper box 5 and for supporting both ends of the paper box 5, thereby assisting the positioning part to move the paper box 5. The contact support 405 may be a U-shaped steel.

[0042] Preferably, as Figure 7As shown, in the embodiment, the moving part may include a mounting base plate 406, a sliding plate 407, a slide rail 408, a slider 409, and a sliding driving member 410. Specifically, the mounting base plate 406 is disposed on the second frame 102. The mounting base plate 406 is a fixed plate and is fixedly mounted on the second frame 102, which can play a role in supporting the transfer positioning assembly 4. The setting position of the mounting base plate 406 is lower than that of the side baffle 404 to avoid interference. The slide rail 408 is disposed on the mounting base plate 406, the slider 409 is disposed on the sliding plate 407, and the sliding plate 407 is slidably disposed on the mounting base plate 406 through the slider 409 and the slide rail 408, so as to realize the sliding of the sliding plate 407, and further drive the positioning part to move. The sliding driving member 410 is disposed on the side of the sliding plate 407 to drive the sliding plate 407 to slide, and the supporting part is disposed on the sliding plate 407. The sliding driving member 410 may be, for example, a cylinder. The cylinder block of the cylinder is fixedly mounted on the mounting base plate 406, and the output end of the cylinder is connected to the sliding plate 407 to realize the sliding of the sliding plate 407.

[0043] Preferably, as Figure 7 shown, in the embodiment, the supporting part may include a guiding telescopic member 411 and a lifting driving member 412. The lifting driving member 412 is disposed on the sliding plate 407. Two ends of the guiding telescopic member 411 are respectively connected to the bearing base plate 401 and the sliding plate 407. The driving end of the lifting driving member 412 is connected to the bearing base plate 401 to drive the bearing base plate 401 to lift. The guiding telescopic member 411 may be a telescopic rod, which plays a role in guiding and limiting. The lifting driving member 412 may be a cylinder.

[0044] Preferably, as Figure 8 shown, in the embodiment, the proximity member 403 may include a connecting plate 4031 and a proximity switch 4032. The middle part of the bearing base plate 401 is hollowed out. The proximity switch 4032 is disposed on the bearing base plate 401 through the connecting plate 4031, and the working end of the proximity switch 4032 is disposed in the middle of the bearing base plate 401.

[0045] Preferably, as Figure 8As shown, in the embodiment, the number of proximity switches 4032 is two. The two proximity switches 4032 are respectively arranged at both ends of the middle part of the hollowed-out carrier bottom plate 401. The two connecting plates 4031 are arranged at the bottom of the carrier bottom plate 401 through a supporting plate 4033. Since the paper box 5 is placed on the carrier bottom plate 401, the two proximity switches 4032 at the middle part of the hollowed-out carrier bottom plate 401 can detect the parallelism of the paper box 5. The specific detection process is as follows: The setting position of the first proximity switch 4032 is close to the front end of the paper box 5, and the setting position of the second proximity switch 4032 is close to the rear end of the paper box 5 (the front and rear here can be understood as the front and rear along the movement of the production line). The first proximity switch 4032 can detect the distance from the front end of the paper box 5 at this time, for example, 1 mm. The second proximity switch 4032 can detect the distance from the rear end of the paper box 5 at this time, for example, 1 mm. The difference between these two distances is within the range required for parallelism, for example, 1 - 3 mm (which can be adjusted according to different specifications of the paper box 5 and is not limited here). The proximity component 403 does not alarm and works normally. If the difference between these two distances exceeds the requirement for parallelism, an alarm signal is sent to prompt the user to check the production status at this time. The user can adjust the pressing and forming mechanism of the pressing and forming process to ensure the parallelism and proper pressing-in of the pressing and forming mechanism.

[0046] The working process of the precise box-closing mechanism for folding boxes is as follows: Since the leveling component 3 and the transfer and positioning component 4 are separately arranged, the parallelism of the two structures can be adjusted during use to ensure the parallelism requirement for the production of the paper box 5. First, through the proximity component 403 of the transfer and positioning component 4, the parallelism of the paper box 5 transferred from the pressing and forming process to the transfer and positioning component 4 is detected. If the parallelism does not meet the requirement, the user can adjust the pressing and forming mechanism of the pressing and forming process to ensure the parallelism and proper pressing-in of the paper box 5. If the parallelism meets the requirement, the next production step is carried out. At this time, the paper box 5 is located below the flanging and box-closing mechanism 2, and operations such as flanging and box-closing are performed. The user can observe the execution status of actions such as pushing the edge, pressing the edge, and closing the box of the paper box 5 at this time. When a situation where the execution cannot be in place due to insufficient parallelism occurs, the adjustment components 303 around the leveling component 3 can be adjusted to make the execution mechanism (such as the flanging and box-closing mechanism 2) parallel to the paper box 5. After all the box-folding actions are adjusted in place, the leveling component 3 is fixed to the main frame 1, thereby realizing precise box-closing of the box-folding equipment, efficient and automated box-folding, and meeting the production requirements of the paper box 5.

[0047] The precise box-closing mechanism for the folding box can realize the leveling adjustment at two places during the production process of the paper box by respectively installing the leveling component and the transfer and positioning component on the first frame and the second frame of the main frame, avoiding the problem of poor forming effect in the process of pressing and forming due to the plasticity of the cardboard. At the same time, in the process of folding and closing the box with the turned edge, the leveling of the turned edge and box-closing mechanism can be ensured, so that the box can be closed in place without manual secondary adjustment, improving the automation rate of the whole production line.

[0048] In addition, according to the second aspect of the present invention, a folding box device is provided, and the folding box device includes the precise box-closing mechanism for the folding box as described above. During the production process of the paper box 5, by installing the precise box-closing mechanism for the folding box, the forming effect of the paper box 5 can be ensured, and at the same time, the automation rate of the folding box production line can be improved.

[0049] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
