Description

Technical Field

[0001] The utility model relates to the technical field of folding box machines, and particularly relates to a folding edge 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 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 through 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 processing 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 there is still room for improvement in the current folding box processing and production solutions, and optimization should be carried out to improve the degree of automation, so as to improve the efficiency of the entire production and processing, 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 proposes a folding edge action component of an automatic folding box machine, which realizes inward folding through automatic actions, and cooperates with automated conveying and processing devices. After the paper box blank is fed in, it can be folded and formed in a set direction. It not only has high efficiency, but also has good accuracy and consistency, and avoids many defects caused by manual operation.

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

[0006] A folding edge action component of an automatic folding box machine includes a first folding edge seat and a second folding edge seat. The second folding edge seat is slidably arranged on the first folding edge seat, and a first folding edge driver is provided between the first folding edge seat and the second folding edge seat to control relative movement; a third folding edge seat is arranged on the second folding edge seat, and a folding edge fork is arranged on the third folding edge seat. The folding edge fork is controlled to deflect by a second folding edge driver. When adopting such a scheme, the first folding edge driver controls the front and back movement of the second folding edge seat, and the second folding edge driver controls the horizontal deflection of the folding edge fork on the third folding edge seat, thereby realizing the lateral folding of the folding edge at the port of the paper box blank.

[0007] Furthermore, the structure of the first hemming seat is not uniquely defined. Here, an optimization is carried out and one feasible option is proposed: the first hemming seat includes a support frame and a mounting plate. The mounting plate is fixed on the support frame. The second hemming seat cooperates with the mounting plate, and a slide rail structure is provided between the second hemming seat and the mounting plate. When adopting such a scheme, the second hemming seat reciprocally slides relative to the first hemming seat through the slide rail structure.

[0008] Furthermore, the structure and installation method of the first hemming driver are not uniquely defined. Here, an optimization is carried out and one feasible option is proposed: the first hemming driver includes a telescopic cylinder. One end of the telescopic cylinder is fixedly cooperated on the mounting plate, and the other end is connected to the second hemming seat and drives the second hemming seat to reciprocally slide along the slide rail structure. When adopting such a scheme, the first hemming driver can also adopt an electric telescopic cylinder and a hydraulic telescopic cylinder.

When adopting such a scheme, the entire L-shaped plate reciprocally slides on the first hemming seat and drives the third hemming seat to move synchronously.

[0010] Furthermore, the structure of the second hemming driver can be constructed in various forms and is not uniquely defined. Here, an optimization is carried out and one feasible option is proposed: the second hemming driver includes a telescopic cylinder. One end of the telescopic cylinder is cooperated with the second hemming seat, and the other end is cooperated with a hemming fork. The telescopic cylinder drives the hemming fork to deflect during the process of extension or shortening.

[0011] Furthermore, when the second hemming driver adopts a telescopic cylinder, the setting method of the telescopic cylinder is not uniquely defined. Here, an optimization is carried out and one feasible option is proposed: the number of the telescopic cylinders is two and they are arranged at intervals longitudinally. The two telescopic cylinders are respectively cooperated with the upper surface and the lower surface of the third hemming seat. When adopting such a scheme, the two telescopic cylinders extend and contract synchronously. Due to the symmetric setting on the upper and lower sides of the third hemming seat, the stability of the deflecting hemming process can be improved.

[0012] Furthermore, when connecting the telescopic cylinder to the L-shaped plate, it can be realized through various schemes and is not uniquely defined. Here, an optimization is carried out and one feasible scheme is proposed: a connecting vertical plate is provided on the L-shaped plate. The end of the telescopic cylinder is horizontally hinged to the connecting vertical plate, and the front end of the telescopic cylinder is horizontally hinged to the hemming fork. When adopting such a scheme, the connecting vertical plate can be integrally formed with the L-shaped plate, or welded and fixed, or connected and formed through fasteners.

[0013] Further, the structure of the third hemming seat is not limited to a single one, and an optimization is made here and one of the feasible options is proposed: the third hemming seat includes a fork connecting plate and a height adjustment block, and the fork connecting plate is connected to the second hemming seat through the height adjustment block and slides synchronously with the second hemming seat. When such a solution is adopted, the hemming fork includes at least two toggle rods.

[0047] Example 2

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides an automatic box folding machine, using the folding action component disclosed in Example 1, including:

[0049] Base mechanism, such as Figure 4 , Figure 5 As shown, it is used to support the load and stabilize the entire box folding machine structure;

[0050] A feeding mechanism, arranged on the base mechanism, for adjusting the carton blank and feeding it into the folding mechanism;

[0051] Transmission mechanism 9, such as Figure 6 , Figure 7 As shown, it 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 folding mechanism, the transmission mechanism 9 keeps the carton blank suspended through the synchronization mechanism 10, and when the folding is completed, the synchronization mechanism 10 releases the carton blank from suspension and continues to move;

[0052] Folding mechanism, such as Figures 9 to 13 As shown, it includes a fixed side operating mechanism 2 and a movable side operating mechanism 4 arranged on the base mechanism. The fixed side operating mechanism 2 and the movable side operating mechanism 4 are arranged opposite to each other and are used to cooperate in folding the front and rear ends, left and right sides and the top cover of the paper box 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 temporarily storing the paper box blanks and providing a platform surface for guiding the cooperation between the paper box blanks and the transmission mechanism 9. Its specific structure is not uniquely defined. In this embodiment, it is optimized and one feasible option is adopted: the feeding mechanism includes a feeding table 1 for placing the paper box blanks. The front side edge of the feeding table 1 is aligned with the transmission mechanism 9 so that the paper box blanks can move in cooperation with the transmission mechanism 9; a lifting assembly 103 is also provided on the front side edge of the feeding table 1, and the lifting assembly 103 is used to lift the folding edge of the paper box blanks so as to cooperate smoothly with the edge folding mechanism. When adopting such a scheme, the lifting assembly 103 can use a pneumatic telescopic cylinder or a hydraulic telescopic cylinder as the power component to lift the front end of the paper box blanks so as to smoothly reach the transmission mechanism 9.

[0057] The structure of the feeding table 1 can adopt various forms and is not uniquely defined. 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 part 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 paper box blanks reach the edge of the connecting panel 102, they are lifted upward by the lifting assembly 103. When adopting such a scheme, 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 paper box blanks reach the edge of the connecting panel 102, they are lifted and then smoothly reach the transmission mechanism 9, and then are folded and formed by the edge folding mechanism.

[0058] The transmission mechanism 9 drives the paper box blanks to move forward, hover for edge folding and then convey them backward after forming. The transmission mechanism 9 can be set in various forms and is not uniquely defined. 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 paper box blanks to move along the edge folding mechanism and hover to complete edge folding; synchronous mechanisms 10 for cooperating with the paper box blanks are arranged on both the first transmission component 901 and the second transmission component 902. When adopting such a scheme, the first transmission component 901 and the second transmission component 902 are arranged in parallel and have an overlapping section. When the paper box blanks reach the overlapping section, they 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, which are not uniquely defined. In this embodiment, optimization is carried out and one feasible option is adopted: both the first transmission component 901 and the second transmission component 902 include synchronous belts, which are driven by the drive motor 105 and travel reciprocally; the synchronous belts are connected to the synchronization mechanism 10 and drive the synchronization mechanism 10 to travel synchronously and reciprocally. When adopting such a solution, the drive motor 105 is a servo motor, and the synchronization mechanism 10 is used to connect the paper box blank and keep it moving synchronously.

[0060] The synchronization mechanism 10 is used to carry the paper box blank and move synchronously, which can be realized by various solutions and is not uniquely defined. In this embodiment, optimization is carried out and one feasible option is adopted: the synchronization mechanism 10 includes a synchronization base 1001, and a number of sucker components 1002 are arranged on the synchronization base 1001. The sucker components 1002 are connected to the sucker air circuit and are used to adsorb the paper box blank. When the paper box blank reaches the transmission mechanism 9, the sucker components 1002 are attached to the paper box blank and discharge air through the sucker air circuit to form negative pressure adsorption, thereby driving the paper box blank to travel synchronously, and the negative pressure adsorption is released by introducing air into the sucker air circuit. When adopting such a solution, the sucker components 1002 are arranged upward. When the paper box blank is located above the sucker components 1002, the two are attached. After the sucker air circuit discharges the internal gas, the paper box blank can be firmly adsorbed, thereby driving the paper box blank to move synchronously.

[0061] Optimize the structure of the synchronization base 1001 and adopt one feasible option: an air cavity is formed inside the synchronization base 1001 and is connected to the sucker mounting openings on its surface. The suckers are connected to the sucker mounting openings and communicate with the air cavity; the air cavity also communicates with the air inlet and the air outlet on the synchronization base, and an air inlet control component and an air outlet control component are respectively arranged at the air inlet and the air outlet. When adopting such a solution, the air inlet control component and the air outlet control component on the synchronization base 1001 include throttle valves.

[0062] When the transmission mechanism 9 drives the paper box blank to travel 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 uniquely defined. In this embodiment, optimization is carried out and one feasible option is adopted: the transmission mechanism 9 further includes a transition support component 903. The transition support component 903 includes a column and a transition top plate on the column. The transition top plate extends from the first transmission component 901 to the second transmission component 902, and the transition top plate includes an upwardly inclined support surface. When adopting such a solution, the transition support component 903 is arranged on the base mechanism, and the paper box blank is lifted up when it travels to the support component along with the transmission mechanism 9.

[0063] In order to convey the carton blank backward, in this embodiment, the transmission mechanism 9 is optimized, and one feasible option is adopted: the transmission mechanism 9 further includes a third transmission component 904, which is connected to the second transmission component 902 and is used to convey the carton blank backward. A lever component 907 is arranged on the third transmission component 904 to push the carton blank forward. When such a solution is adopted, the lever component 907 moves forward synchronously with the carton blank.

[0064] The lever component 907 can be set in various structures and is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the lever component 907 includes a lever arm arranged on the third transmission component 904 and moving cyclically with the third transmission component 904. When the carton blank moves with the second transmission component 902 and reaches the third transmission component 904, it is pushed forward by the lever arm. When such a solution is adopted, the lever arm is hinged to the third transmission component 904 and can deflect within a certain angle in the longitudinal direction.

[0065] The specific installation structure of the transmission mechanism 9 is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the transmission mechanism 9 further includes a transmission frame body, which includes a transmission base 905 and several support frame groups 906 arranged on the transmission base 905. The first support frame group 906 arranged on the transmission base 905 is used to cooperate with and fix the first transmission component 901, the second support frame group 906 is used to cooperate with and fix the second transmission component 902, and the third support frame group 906 is used to cooperate with and fix the third transmission component 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 component 904 can adopt various transmission structures and is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the third transmission component 904 includes a transmission chain plate fixed in cooperation with the third support frame group 906. A chain that circulates and moves forward is arranged on the transmission chain plate, and a third drive motor 105 used to drive the chain to rotate and move forward is also connected to the transmission chain plate. When such a solution is adopted, the lever component 907 is arranged on the chain and moves synchronously and cyclically 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, various methods can be adopted and it is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: such as Figure 8As shown in the figure, it further includes a middle-position pressing edge mechanism 3 for using the following 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 guiding plate 302 arranged along the advancing direction of the carton blank. The middle-position guiding plate 302 is horizontally arranged, and the lower surface of the middle-position guiding plate 302 forms a horizontal middle-position guiding surface. Both sides of the middle-position guiding plate 302 form laterally upwardly curved guiding surfaces. When adopting such a scheme, a traveling gap is formed between the middle-position guiding plate 302 and the conveying surface of the transmission mechanism 9, and the carton blank enters the traveling gap to maintain smooth conveying.

[0068] During the traveling process of the carton blank, it is also guided into the traveling gap. The specific structure is not uniquely defined. In this embodiment, it is optimized and one feasible option is adopted: The front end of the middle-position guiding plate 302 is connected with a 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. Both sides of the feeding guiding plate 301 form laterally upwardly curved guiding surfaces. When adopting such a scheme, the feeding guiding plate 301 and the middle-position guiding plate 302 can be integrally formed or 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, it is optimized and one feasible option is adopted: The holding assembly 305 moves outwardly actively towards both sides of the guiding frame to form a pressing 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, it is optimized and one feasible option is adopted: The holding assembly 305 includes a horizontally arranged X-shaped telescopic frame, and a pressing block is arranged on the X-shaped telescopic frame. When the X-shaped telescopic frame shortens, the pressing block moves outwardly actively towards both sides of the guiding frame. When adopting such a scheme, the X-shaped telescopic frame can maintain stability by pressing on both sides.

[0072] For the convenience of sliding and telescoping, in this embodiment, it is optimized and one feasible option is adopted: A slide rail is arranged on the guiding frame, and several sliders are arranged in cooperation with the slide rail. The X-shaped telescopic frame is at least connected in cooperation 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 to prevent loosening and detachment.
