Description

Technical Field

[0001] The utility model relates to the technical field of folding box machines, and particularly relates to a flanging action component of an automatic folding box machine. Background Art

[0002] At present, many commodities are packaged in packing boxes and packaging boxes and then sold on the market as finished products. Especially for items that are easily damaged by bumps on the outside, they require the protection of packaging boxes. Currently, most packaging boxes are formed by folding cardboard after processing to form a space for accommodating items. With the increasing number of commodities, the demand for packaging boxes has also increased sharply. The traditional processing and production method of packaging boxes mainly involves manual participation, either through pure manual folding or through semi-automatic processing and production assisted by equipment. This has the problems of low efficiency, poor consistency of finished products, and high labor costs, and cannot meet the current growing demand.

[0003] It can be seen that the current folding box processing and production scheme still has room for improvement. It should be optimized to improve the degree of automation, so as to improve the efficiency of the entire production and processing, improve the accuracy of processed finished products, and reduce the overall cost. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the prior art. Summary of the Utility Model

[0004] To at least overcome one of the above-mentioned defects, the utility model provides a flanging action component of an automatic folding box machine, which folds and forms a paper box blank through the flanging action component, and cooperates with an automated conveying and processing device to fold and form the paper box blank in a specified direction after it is fed in. It not only has high efficiency, but also has good accuracy and consistency, and avoids many defects caused by manual operation.

[0005] To achieve the above purpose, the automatic folding box machine disclosed by the utility model can adopt the following technical solutions:

[0006] A flanging action component of an automatic folding box machine includes a flanging base, a folding arm is arranged on the flanging base in a matching manner, the folding arm rotates relative to the flanging base, and a flanging shaft is connected to the folding arm. The flanging shaft drives a flanging pressing plate to deflect between a flat position and a flanging position. When the flanging pressing plate is in the flat position, it is lower than the bottom of the paper box blank and allows the paper box blank to pass through from above. When the flanging pressing plate is in the flanging position, it drives the folding edge at the port of the paper box blank to be longitudinally folded. When adopting such a scheme, the sealing plate at the port of the paper box blank is driven to turn up by the flanging action component.

[0007] Furthermore, when the flanging base is in operation, it can be realized through various schemes. Here, one feasible option is optimized and proposed: a flanging driver is arranged on the flanging base, and the flanging driver cooperates with the folding arm and is used to drive the folding arm to deflect, thereby driving the flanging shaft to rotate so that the flanging pressing plate deflects.

[0008] Further, the structure of the flanging base can be configured in various forms. Here, it is optimized and one feasible option is proposed: An axle seat structure is provided on the flanging base, and a drive shaft that rotates relative to the flanging base is provided on the axle seat structure. The end of the flanging drive is connected and cooperates with the drive shaft.

[0009] Further, the structure of the drive shaft can be optimized. Here, one feasible option is proposed: A clamping groove is provided on the drive shaft, and a clamping plate is fixedly installed in the clamping groove. The flanging drive is fixedly connected to the clamping plate and rotates synchronously with the drive shaft. When such a solution is adopted, the clamping plate is embedded in the clamping groove, and when the drive shaft rotates, it drives the clamping plate to rotate synchronously.

[0010] Further, the flanging drive includes a telescopic cylinder.

[0011] Further, in order to make the folding arm drive the flanging shaft to move more smoothly, here it is optimized and one feasible option is proposed: A shaft hole is formed in the middle of the folding arm and is rotationally connected and cooperates with the folding base. The shaft hole extends towards the end of the folding arm to form a first extension section and is hinged and cooperates with the flanging drive; the shaft hole extends towards the front end of the folding arm to form a second extension section and is connected and cooperates with the flanging shaft. When such a solution is adopted, the first extension section and the second extension section of the folding arm are integrally formed.

[0012] Further, the structure of the flanging shaft is optimized. Here, one feasible option is proposed: A flanging connection seat for connecting the flanging pressing plate is provided on the flanging shaft. The flanging connection seat flips synchronously with the flanging shaft and drives the flanging pressing plate to deflect synchronously. When such a solution is adopted, the flanging connection seat adopts an integral connection block and is fixedly connected to the flanging shaft.

[0013] Further, in order to improve the protection effect on the carton blank, the structure at the flanging pressing plate is optimized, and the following feasible option is proposed: A flanging elastic sheet is provided between the flanging pressing plate and the flanging connection seat. When such a solution is adopted, the number of flanging elastic sheets is several, and metal elastic sheets can be used.

[0014] Further, the setting method of the flanging elastic sheet is optimized and one feasible option is proposed: The number of flanging elastic sheets is several and they are arranged at intervals along the length direction of the flanging connection seat.

[0015] Furthermore, the flanging elastic sheet includes a Z-shaped elastic sheet.

[0034] The following further explains the present utility model in conjunction with the drawings and specific embodiments.

[0035] In view of the many defects existing in manual operation in the prior art, the following embodiments are optimized to overcome the defects existing in the prior art.

[0036] Embodiment 1

[0037] An edge-folding action component of an automatic box folding machine can be constructed in various forms and is not uniquely limited. In this embodiment, optimization is carried out and one of the feasible options is adopted: The edge-folding action component includes an edge-folding base, on which a folding arm is cooperatively arranged. The folding arm rotates relative to the edge-folding base, and an edge-folding shaft is connected to the folding arm. The edge-folding shaft drives the edge-folding pressing plate to deflect between a flat position and an edge-folding position. When the edge-folding pressing plate is in the flat position, it is lower than the bottom of the paper box blank and allows the paper box blank to pass from above. When the edge-folding pressing plate is in the edge-folding position, it drives the folding edge of the port of the paper box blank to be longitudinally folded. When such a scheme is adopted, the sealing plate at the port of the paper box blank is driven to turn up by the edge-folding action component.

[0038] When the edge-folding base is in operation, it can be realized through various schemes. In this embodiment, optimization is carried out and one of the feasible options is adopted: A edge-folding driver is arranged on the edge-folding base. The edge-folding driver cooperates with the folding arm and is used to drive the folding arm to deflect, thereby driving the edge-folding shaft to rotate so that the edge-folding pressing plate deflects.

[0039] The structure of the edge-folding base can be constructed in various forms.

In this embodiment, one of the feasible options is adopted: A clamping groove is arranged on the driver shaft, a clamping plate is installed and fixed in the clamping groove, and the edge-folding driver is connected and fixed to the clamping plate and rotates synchronously with the driver shaft. When such a scheme is adopted, the clamping plate is embedded in the clamping groove, and when the driver shaft rotates, it drives the clamping plate to rotate synchronously.

[0041] Preferably, in this embodiment, the edge-folding driver includes a telescopic cylinder.

[0042] In order to make the folding arm drive the edge-folding shaft to act more smoothly, in this embodiment, optimization is carried out and one of the feasible options is adopted: A shaft hole is formed in the middle of the folding arm and is rotationally connected and cooperated with the edge-folding base. The shaft hole extends to the end of the folding arm to form a first extension section and is hinged and cooperated with the edge-folding driver; the shaft hole extends to the front end of the folding arm to form a second extension section and is connected and cooperated with the edge-folding shaft. When such a scheme is adopted, the first extension section and the second extension section of the folding arm are integrally formed.

[0043] The structure of the edge-folding shaft is optimized. In this embodiment, one of the feasible options is adopted: An edge-folding connection seat for connecting the edge-folding pressing plate is arranged on the edge-folding shaft. The edge-folding connection seat rotates synchronously with the edge-folding shaft and drives the edge-folding pressing plate to deflect synchronously. When such a scheme is adopted, the edge-folding connection seat adopts an integral connection block and is connected and fixed to the edge-folding shaft.

[0044] In order to improve the protection effect on the carton blank, the structure at the flanging pressure plate is optimized, and the following is a feasible option: a flanging elastic piece is arranged between the flanging pressure plate and the flanging connecting seat. When adopting such a scheme, the number of flanging elastic pieces is several, and metal elastic pieces can be used.

[0045] Optimize the setting method of the flanging elastic piece and adopt one of the feasible options: the number of the flanging elastic pieces is several and they are arranged at intervals along the length direction of the flanging connecting seat.

[0046] Preferably, in this embodiment, the flanging elastic piece includes a Z-shaped elastic piece.

[0047] Embodiment 2

[0048] As Figure 1 、 Figure 2 、 Figure 3 shown, this embodiment provides an automatic carton folding machine, which adopts the flanging action component in Embodiment 1 and includes:

[0049] A base mechanism, as Figure 4 、 Figure 5 shown, used to support the load and stabilize the entire carton folding machine structure;

[0050] A feeding mechanism, arranged on the base mechanism, used to adjust the carton blank and feed it into the flanging mechanism;

[0051] A transmission mechanism 9, as Figure 6 、 Figure 7 shown, continuously cooperates with the feeding mechanism and is used to drive the carton blank to move forward along the set direction. And when the carton blank moves to the flanging mechanism, the transmission mechanism 9 keeps the carton blank hovering through the synchronization mechanism 10. When the flanging is completed, the synchronization mechanism 10 releases the hovering of the carton blank and continues to move forward;

[0052] A flanging mechanism, as Figures 9 to 13 shown, includes a fixed-side operating mechanism 2 and a moving-side operating mechanism 4 arranged on the base mechanism. The fixed-side operating mechanism 2 and the moving-side operating mechanism 4 are arranged opposite to each other and are used to cooperate to fold the front and rear ends, left and right sides, and the top cover of the carton blank to form a complete box body.

[0053] The automatic box folding machine disclosed in this embodiment is loaded by a base mechanism. The carton blank is transported from the feeding mechanism to the transmission mechanism 9, and its multiple sides are folded through the folding mechanism. The long sides of the carton blank are folded at the folding position of the folding mechanism to form vertical side panels and a box cover on both sides, and the box cover is kept in an open state and continues to be transported backward; when transported to the first folding position, the front end of the carton blank is folded inward and turned up to complete the closure of the front end of the box body; when transported to the second folding position, the rear end of the carton blank is folded inward and turned up to complete the closure of the rear section of the box body. The opened box body can be obtained by continuing to transport it backward, and can be directly used as packaging.

[0054] The base mechanism can be in various forms, which are not limited to the only one. This embodiment optimizes and adopts one of the feasible options: the base mechanism includes a carrier frame 104, on which a plurality of drive motors 105 are arranged, and the drive motors 105 are coordinated to operate synchronously through a synchronization rod 106, and the synchronization rod 106 is used to cooperate with the feeding mechanism and the transmission mechanism 9 and provide driving force. When such a solution is adopted, the base mechanism can be formed by splicing steel columns and steel beams.

[0055] In order to ensure that the structure of the carton blank is more stable during the folding process and can be bonded simultaneously, the specific solution is not limited to the only one. This embodiment is optimized and adopts one of the feasible options: it also includes a glue dispensing mechanism, which is used to dispense glue on the carton blank to assist the carton blank in folding and bonding. When such a solution is adopted, the glue dispensing mechanism includes a glue dispensing head and dispenses glue on the corresponding veneer of the folded edge or the box body.

[0056] The feeding mechanism can be used for temporary storage of carton blanks, and provides a platform surface for guiding the carton blanks to cooperate with the transmission mechanism 9. The specific structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the feeding mechanism includes a feeding table 1 for placing carton blanks, and the front side of the feeding table 1 is aligned with the transmission mechanism 9 so that the carton blanks can move in coordination with the transmission mechanism 9; the front side of the feeding table 1 is also provided with a lifting component 103, and the lifting component 103 is used to lift the folding edge of the carton blank so as to cooperate with the folding mechanism. When such a solution is adopted, the lifting component 103 can use a pneumatic telescopic cylinder or a hydraulic telescopic cylinder as a power part to lift the front end of the carton blank so that it can be smoothly put on the transmission mechanism 9.

[0057] The structure of the re-feeding table 1 can adopt various forms and is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the feeding table 1 includes a feeding machine frame, the top of the feeding machine frame is connected with a top panel 101 and a connecting panel 102, and the side of the feeding machine frame is connected with a side panel; the lifting assembly 103 is arranged on the feeding machine frame and is located outside the connecting panel 102. When the carton blank reaches the edge of the connecting panel 102, it is lifted upward by the lifting assembly 103. When such a solution is adopted, the top panel 101 and the connecting panel 102 are made of metal plates, and the lifting assembly 103 is located at the edge of the connecting panel 102. When the carton blank reaches the edge of the connecting panel 102, it is lifted and thus smoothly reaches the transmission mechanism 9, and then is folded and formed by the folding mechanism.

[0058] The transmission mechanism 9 drives the carton blank to move forward, hovers for folding and then conveys it backward. The transmission mechanism 9 can be set in various forms and is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the transmission mechanism 9 includes a first transmission component 901 and a second transmission component 902. The first transmission component 901 and the second transmission component 902 are arranged in succession and are used to drive the carton blank to move along the folding mechanism and hover to complete folding; synchronization mechanisms 10 are arranged on both the first transmission component 901 and the second transmission component 902. When such a solution is adopted, the first transmission component 901 and the second transmission component 902 are arranged in parallel and have an overlapping section. When the carton blank reaches the overlapping section, it can transition from the first transmission component 901 to the second transmission component 902.

[0059] The structures of the first transmission component 901 and the second transmission component 902 can adopt various solutions and are not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: both the first transmission component 901 and the second transmission component 902 include synchronous belts, and the synchronous belts are driven by a drive motor 105 to move back and forth; the synchronous belts are connected to the synchronization mechanisms 10 and drive the synchronization mechanisms 10 to move back and forth synchronously. When such a solution is adopted, the drive motor 105 adopts a servo motor, and the synchronization mechanism 10 is used to connect the carton blank and keep it moving synchronously.

[0060] The synchronization mechanism 10 is used to carry the carton blank to move synchronously, which can be realized by a variety of schemes, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the synchronization mechanism 10 includes a synchronization base 1001, and a plurality of suction cups 1002 are arranged on the synchronization base 1001. The suction cups 1002 are connected to the suction cup air path and used to absorb the carton blank. When the carton blank reaches the transmission mechanism 9, the suction cups 1002 fit the carton blank and discharge air through the suction cup air path to form negative pressure absorption, thereby driving the carton blank to move synchronously, and the negative pressure absorption is released by introducing air through the suction cup air path. When such a scheme is adopted, the suction cups 1002 are arranged upward, and when the carton blank is located above the suction cups 1002, the two fit together. After the suction cup air path discharges the internal gas, the carton blank can be firmly absorbed, thereby driving the carton blank to move synchronously.

[0061] The structure of the synchronous base 1001 is optimized and one of the feasible options is adopted: an air cavity is formed in the synchronous base 1001 and connected to the suction cup installation port on its surface, the suction cup is connected to the suction cup installation port and connected to the air cavity; the air cavity is also connected to the air inlet and the air outlet on the synchronous base, and the air inlet and the air outlet are respectively provided with an air inlet control component and an air outlet control component. When such a solution is adopted, the air inlet control component and the air outlet control component on the synchronous base 1001 include a throttle valve.

[0062] When the transmission mechanism 9 drives the carton blank to move and transition, it maintains a smooth transition and avoids jamming or interference. Therefore, it can be achieved by adjusting the structure of the transmission mechanism 9, which is not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the transmission mechanism 9 also includes a transition support assembly 903, the transition support assembly 903 includes a column and a transition top plate on the column, the transition top plate extends from the first transmission assembly 901 to the second transmission assembly 902, and the transition top plate includes an upwardly inclined support surface. When such a solution is adopted, the transition support assembly 903 is arranged on the base mechanism, and is lifted up when the carton blank moves to the support assembly with the transmission mechanism 9.

[0063] In order to transport the carton blank backward, the present embodiment optimizes the transmission mechanism 9 and adopts one of the feasible options: the transmission mechanism 9 further includes a third transmission assembly 904, which is connected to the second transmission assembly 902 and is used to transport the carton blank backward, and a lever assembly 907 is provided on the third transmission assembly 904 to move the carton blank forward. When such a solution is adopted, the lever assembly 907 moves synchronously with the carton blank.

[0064] The lever assembly 907 can be configured in a variety of structures and is not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: the lever assembly 907 includes a lever arm disposed on the third transmission assembly 904 and traveling cyclically with the third transmission assembly 904. When the carton blank moves with the second transmission assembly 902 and reaches the third transmission assembly 904, it is toggled forward by the lever arm. When such a solution is adopted, the lever arm is hinged to the third transmission assembly 904 and can deflect within a certain longitudinal angle.

[0065] The specific installation structure of the transmission mechanism 9 is not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: the transmission mechanism 9 further includes a transmission frame body, which includes a transmission base 905 and a number of support frame groups 906 disposed on the transmission base 905. The first support frame group 906 disposed on the transmission base 905 is used to cooperate with and fix the first transmission assembly 901, the second support frame group 906 is used to cooperate with and fix the second transmission assembly 902, and the third support frame group 906 is used to cooperate with and fix the third transmission assembly 904. When such a solution is adopted, the first support frame group 906, the second support frame group 906, and the third support frame group 906 are all detachable structures.

[0066] The third transmission assembly 904 can adopt a variety of transmission structures and is not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: the third transmission assembly 904 includes a transmission chain plate that cooperates with and is fixed to the third support frame group 906. A chain that runs cyclically forward is provided on the transmission chain plate, and a third drive motor 105 for driving the chain to rotate forward is also connected to the transmission chain plate. When such a solution is adopted, the lever assembly 907 is disposed on the chain and moves cyclically synchronously with the chain.

[0067] During the process of the carton blank being transmitted forward, in order to keep the carton blank stable, the carton blank is limited and pressed. Specifically, a variety of methods can be adopted, which are not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: as Figure 8 shown, it further includes a middle-position pressing edge mechanism 3 for pressing down the carton blank to keep the carton blank in contact with the transmission mechanism 9. The middle-position pressing edge mechanism 3 includes a middle-position guide plate 302 disposed along the traveling direction of the carton blank. The middle-position guide plate 302 is horizontally arranged and the lower surface of the middle-position guide plate 302 forms a horizontal middle-position guide surface. The two sides of the middle-position guide plate 302 form laterally upwardly curved side-position guide surfaces. When such a solution is adopted, a traveling gap is formed between the middle-position guide plate 302 and the conveying surface of the transmission mechanism 9, and the carton blank enters the traveling gap to maintain stable conveying.

[0068] During the advancement of the paper box blank, it is also guided into the advancing gap. The specific structure is not uniquely defined. In this embodiment, optimization is carried out and one of the feasible options is adopted: the front end of the middle-position guiding plate 302 is connected to the feeding guiding plate 301. The width of the feeding guiding plate 301 is greater than the width of the middle-position guiding plate 302, and the lower surface of the feeding guiding plate 301 is a horizontal guiding surface. The two sides of the feeding guiding plate 301 form upwardly curved side-position guiding surfaces. When adopting such a scheme, the feeding guiding plate 301 and the middle-position guiding plate 302 can be integrally formed or can be connected and fixed by fasteners.

[0069] A guiding frame is arranged on the middle-position guiding plate 302, and a holding assembly 305 is arranged on the guiding frame.

[0070] The holding assembly 305 can adopt various structures. In this embodiment, optimization is carried out and one of the feasible options is adopted: the holding assembly 305 moves outwardly actively towards the two sides of the guiding frame and forms a tightening structure. When adopting such a scheme, the holding assembly 305 can help the guiding frame maintain an intermediate position between the fixed-side operating mechanism 2 and the moving-side operating mechanism 4.

[0071] The structure of the holding assembly 305 can be constructed in various forms and is not uniquely defined. In this embodiment, optimization is carried out and one of the feasible options is adopted: the holding assembly 305 includes a horizontally arranged X-shaped telescopic frame, and a tightening block is arranged on the X-shaped telescopic frame. When the X-shaped telescopic frame shortens, the tightening block moves outwardly actively towards the two sides of the guiding frame. When adopting such a scheme, the X-shaped telescopic frame can maintain stability by tightening the two sides.

[0072] In order to facilitate sliding and telescoping, in this embodiment, optimization is carried out and one of the feasible options is adopted: a slide rail is arranged on the guiding frame, and a number of sliders are cooperatively arranged on the slide rail. The X-shaped telescopic frame is at least cooperatively connected with two sliders, and when the two sliders approach each other, the X-shaped telescopic frame is pushed to shorten. When adopting such a scheme, the slide rail and the slider can be provided with a notch structure for preventing loosening and detachment.

[0073] The structure of the guiding frame can be constructed in various forms and is not uniquely defined. In this embodiment, optimization is carried out and one of the feasible options is adopted: the guiding frame includes a number of guiding columns 303 perpendicularly connected to the middle-position guiding plate 302. The upper ends of the guiding columns 303 are connected to a guiding cross beam 304, and the holding assembly 305 is cooperatively arranged on the guiding cross beam 304. When adopting such a scheme, the guiding cross beam 304 extends along the advancing direction of the paper box blank.

[0074] The fixed-side operating mechanism 2 and the moving-side operating mechanism 4 can be configured in various schemes, which are not uniquely limited. In this embodiment, optimization is carried out and one of the feasible options is adopted: the fixed-side operating mechanism 2 includes a fixed-side operating frame, and the fixed-side operating frame is fixedly connected to the base mechanism; the moving-side operating mechanism 4 includes a moving-side operating frame, and the moving-side operating frame is slidably connected to the base mechanism and is relatively close to or far from the fixed-side operating mechanism 2.
