Description

Technical Field

[0001] This utility model belongs to the technical field of express document bag processing equipment, specifically relating to a folding processing device for express document bags. Background Technology

[0002] In existing technology, express delivery document bags are typically formed from sheet-like document bag materials. These sheets mainly consist of a main body and a back panel. The main body, except for the three perimeters that connect to the back panel, has adhesive application areas. During processing, workers fold the back panel over the main body and then apply glue to the adhesive application areas. This process of folding the adhesive application areas completes the processing of the express delivery document bag. The folding of the back panel over the main body is done manually, resulting in low processing efficiency.

[0003] Chinese patent publication number "CN217125307U" discloses a large-capacity packaging bag folding mechanism, comprising: a device base, which is placed on the ground via bottom support legs; a fixed frame, which is fixedly connected to the top of the device base, and an electric slide rail is installed on the inner side of the top of the fixed frame; a squeezing roller, which is rotatably mounted on the inner side of the bottom of a mounting frame, a slider is slidably mounted on the bottom of the electric slide rail, and a first hydraulic rod is fixedly mounted on the bottom of the slider, the movable end of the first hydraulic rod is fixedly connected to the mounting frame, and a connecting frame is slidably mounted up and down inside the mounting frame; wherein, springs are installed on both the front and rear sides inside the mounting frame to reset the connecting frame downwards.

[0004] The aforementioned folding mechanism can compress and shape the edges of the initially folded packaging bag, ultimately forming the desired packaging bag body. However, during processing, it is still necessary to manually fold the back of the packaging bag towards the main body, and then place each completed packaging bag individually into the folding mechanism for compression and folding. This process requires workers to spend a considerable amount of time performing the initial folding, individual placement, and final unloading steps, resulting in low processing efficiency and a heavy workload for the workers. Utility Model Content

[0005] To overcome the shortcomings of existing technology, this utility model provides a folding processing device for express delivery document bags, which solves the technical problem of low processing efficiency and heavy workload for workers when folding document bag sheets.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A folding processing device for express document bags includes a frame body, a directional transmission mechanism, a folding processing component, and two edge pressing output components mounted on the frame body.

[0007] The directional conveying mechanism has two conveying surfaces that fit together vertically to form a pressing conveying of the document bag sheet.

[0008] The folding processing assembly includes a guide conveying assembly and a guide rod assembly. The guide conveying assembly is installed outside the auxiliary conveying assembly, and its conveying surface gradually slopes in the conveying direction from the outside to the inside.

[0009] The guide rod assembly includes a limiting guide rod, a folding guide rod, and multiple support assemblies. The limiting guide rod and the folding guide rod are fixed to the machine tool body at intervals via corresponding support assemblies. The end of the folding guide rod near the input end of the guide conveying assembly is lower than the conveying surface of the guide conveying assembly. The folding guide rod gradually rises along the conveying direction of the auxiliary conveying assembly and moves closer to the limiting guide rod.

[0010] Furthermore, the guiding and conveying assembly includes a guide conveyor belt, an inclined guide member, a guide drive motor, and multiple guide rollers. The guide rollers are spaced apart on the frame body and are connected to each other via the guide conveyor belt. The output shaft of the guide drive motor is connected to the shaft of one of the guide rollers. The inclined guide member is located in the middle of the guide conveyor belt and has an inclined guide surface on its inner side. The inclined guide surface abuts against the guide conveyor belt, causing the guide conveyor belt to tilt and twist.

[0011] Furthermore, the folding guide rod is arranged along the conveying direction of the guide conveyor assembly and is sequentially divided into a support part, a folding part, and a pressing part. The support part is inclined, and its outer end is lower than the conveying surface of the guide conveyor belt input end. The starting end of the folding part is higher than the conveying surface of the guide conveyor belt and gradually rises along the conveying direction of the guide conveyor assembly. The folding part moves towards the limiting guide rod side in the direction from the outside to the inside. The pressing part gradually decreases along the conveying direction of the guide conveyor assembly, and the distance between its end and the two mating conveying surfaces in the directional conveying mechanism is the sum of the thickness of the main body and the back side of the document bag sheet.

[0012] Furthermore, the directional conveying mechanism includes a sheet conveying assembly, an auxiliary conveying assembly, a first limiting conveying assembly, and a second limiting conveying assembly; the first limiting conveying assembly and the second limiting conveying assembly are respectively arranged directly above the sheet conveying assembly and the auxiliary conveying assembly, and the conveying surfaces of the first and second limiting conveying assemblies are in contact with each other to form a pressing conveying of the document bag sheet.

[0013] Furthermore, the conveying length of the second limiting conveying component is half that of the first limiting conveying component. The starting end of the folded edge is flush with the conveying end of the second limiting conveying component.

[0014] Furthermore, the sheet conveying assembly and the auxiliary conveying assembly have the same structure, both including a sheet conveyor belt, a conveyor drive motor, and multiple conveyor rollers. Each conveyor roller is rotatably connected to the main frame and is connected to each other via the sheet conveyor belt. The conveyor drive motor is mounted on the main frame, and its output shaft is connected to one of the conveyor rollers.

[0015] Furthermore, the first limiting conveying assembly and the pressing output assembly have the same structure, both including a pressing conveyor belt, a pressing drive motor, and pressing rollers. Each pressing roller is rotatably connected to the frame body and is connected to each other via the pressing conveyor belt. The lower conveying surface of the pressing conveyor belt is in contact with the corresponding sheet conveyor belt. The pressing drive motor is mounted on the frame body, and its output shaft is connected to one of the pressing rollers.

[0016] Furthermore, the input end of the pressing conveyor belt is provided with an inlet guide. The inlet guide has an inwardly inclined guide slope on the side near the input end of the pressing conveyor belt.

[0017] Compared with the prior art, the present invention has the following advantages: This invention features a folding guide rod along the conveying path of the directional conveying mechanism. The end of the folding guide rod near the input of the guiding conveying component is lower than the conveying surface of the guiding conveying component. It gradually rises along the conveying direction of the auxiliary conveying component and moves towards the limiting guide rod. This allows the back side of the document bag sheet to automatically fold as it passes the folding guide rod during the directional conveying process, achieving automated folding of the document bag sheet without manual intervention, thus reducing the processing burden on workers.

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and 2 As shown, a folding processing device for express delivery document bags can fold the back side of the unfolded document bag sheet towards the main body to initially form the main structure of the document bag. The device includes a frame body 1, and a directional transmission mechanism 2, a folding processing component 3, and two edge pressing output components 4 mounted on the frame body 1.

[0023] like Figure 2 As shown, the directional conveying mechanism 2 includes a sheet conveying assembly 5, an auxiliary conveying assembly, a first limiting conveying assembly 6, and a second limiting conveying assembly 7. The sheet conveying assembly 5 and the auxiliary conveying assembly are arranged at intervals on the frame body 1, forming a conveying area for the document bag sheet. The first limiting conveying assembly 6 and the second limiting conveying assembly 7 are respectively positioned directly above the sheet conveying assembly 5 and the auxiliary conveying assembly, with their conveying surfaces in contact with each other, forming a pressing conveying effect on the document bag sheet.

[0024] like Figure 2 and 3As shown, the folding processing assembly 3 includes a guide conveying assembly 8 and a guide rod assembly 9. The guide conveying assembly 8 is installed outside the auxiliary conveying assembly to provide support for the back side of the document bag sheet. The conveying surface of the guide conveying assembly 8 gradually slopes in the conveying direction from the outside to the inside, thereby cooperating with the guide rod assembly 9 to guide the back side of the document bag sheet to fold and flip.

[0025] like Figure 3 and 4 As shown, the guide rod assembly 9 includes a limiting guide rod 10, a folding guide rod 11, and multiple support assemblies. The limiting guide rod 10 and the folding guide rod 11 are respectively fixed to the first limiting conveying assembly 6 and the guiding conveying assembly 8 via corresponding support assemblies. The end of the folding guide rod 11 near the input end of the guiding conveying assembly 8 is lower than the conveying surface of the guiding conveying assembly 8. The folding guide rod 11 gradually rises along the conveying direction of the auxiliary conveying assembly and moves closer to the limiting guide rod 10. The folding guide rod 11 gradually descends as it passes the middle region between the first limiting conveying assembly 6 and the guiding conveying assembly 8, enabling it to work with the guiding conveying assembly 8 to gradually lift, flip, and fold the back side of the document bag sheet during the conveying process.

[0026] Specifically, such as Figure 3 As shown, the guiding and conveying assembly 8 includes a guiding conveyor belt 12, an inclined guide member 13, a guiding drive motor, and multiple guide rollers. The guide rollers are spaced apart on the frame body 1 and are connected to each other via the guiding conveyor belt 12. The output shaft of the guiding drive motor is connected to the rotating shaft of one of the guide rollers.

[0027] An inclined guide 13 is disposed in the middle of the guide conveyor belt 12, and has an inclined guide surface on its inner side. The inclined guide surface abuts against the guide conveyor belt 12 and causes the guide conveyor belt 12 to tilt and twist, forming an inclined conveying surface, which can cause the document bag sheet to flip when it passes by.

[0028] In the actual processing, the guide drive motor drives the corresponding guide roller to rotate. Under the tension and cooperation of the guide conveyor belt 12 and the other guide rollers, the guide conveyor belt 12 is driven to move. When the guide conveyor belt 12 moves the document bag sheet to the position of the inclined guide 13, it will cause the bottom edge of the back part of the document bag sheet to flip upward.

[0029] like Figure 4 and 5As shown, the folding guide rod 11 is arranged along the conveying direction of the guide conveyor assembly 8, and is sequentially divided into a support part 11-1, a folding part 11-2, and a pressing part 11-3. The support part 11-1 is inclined, and its outer end is lower than the conveying surface of the input end of the guide conveyor belt 12. The distance between the support part 11-1 and the limiting guide rod 10 is greater than the width of the main body of the document bag sheet, but less than the combined width of the main body and the back side. When the back side of the document bag sheet passes the support part 11-1 under the conveying of the auxiliary conveyor assembly, it will gradually flip upwards through the support part 11-1. The folding part 11-2 has an arc-shaped structure, and its starting end is higher than the conveying surface of the guide conveyor belt 12. The folding part 11-2 gradually rises along the conveying direction of the guide conveyor assembly 8 and moves towards the limiting guide rod 10. During processing, the back side of the document bag sheet, guided upward by the support part 11-1, is gradually folded towards the main body of the document bag sheet under the guidance of the folding part 11-2. The pressing part 11-3 gradually decreases along the conveying direction of the guide conveying assembly 8, and the distance between its end and the auxiliary conveying assembly is the sum of the thicknesses of the main body and the back side of the document bag sheet, thereby achieving pressing treatment of the back side after folding.

[0030] In this embodiment, the conveying length of the second limiting conveying component 7 is half that of the first limiting conveying component 6. The starting end of the folded edge portion 11-2 is flush with the conveying end of the second limiting conveying component 7, ensuring that the folded edge portion 11-2 can be smoothly flipped when it moves the back side of the document bag sheet.

[0031] like Figure 6 As shown, the sheet conveying assembly 5 and the auxiliary conveying assembly have the same structure, both including a sheet conveyor belt 14, a conveyor drive motor, and multiple conveyor rollers 15. Each conveyor roller 15 is rotatably connected to the frame body 1 and is connected to each other via the sheet conveyor belt 14. The conveyor drive motor is mounted on the frame body 1, and its output shaft is connected to one of the conveyor rollers 15, driving it to rotate. This, in turn, drives the sheet conveyor belt 14 and the remaining conveyor rollers 15 to rotate, thus conveying the document bag sheet.

[0032] like Figure 6 As shown, the first limiting conveyor assembly 6 and the pressing output assembly 4 have the same structure, both including an inlet guide 16, a pressing conveyor belt 17, a pressing drive motor, and pressing rollers 18. Each pressing roller 18 is rotatably connected to the frame body 1 and is connected to each other via the pressing conveyor belt 17. The lower conveying surface of the pressing conveyor belt 17 is in contact with the corresponding sheet conveyor belt 14.

[0033] The edge-pressing drive motor is mounted on the frame body 1, and its output shaft is connected to one of the edge-pressing rollers 18. An inlet guide 16 is mounted on the input end of the edge-pressing conveyor belt 17, and an inwardly inclined guide ramp is provided on the side near the input end of the edge-pressing conveyor belt 17. The edge-pressing conveyor belt 17 is wrapped around the outer ring of the inlet guide 16 and fits against the guide ramp, thus guiding the document bag sheet and ensuring that the document bag sheet enters the limiting area formed between the edge-pressing conveyor belt 17 and the sheet conveyor belt 14.

[0034] In this embodiment, the only difference between the second limiting conveyor assembly 7 and the first limiting conveyor assembly 6 is that the length of the pressing conveyor belt 17 in the second limiting conveyor assembly 7 is half the length of the pressing conveyor belt 17 in the first limiting conveyor assembly 6. The rest are the same, so they will not be described in detail here.

[0035] The working principle of this utility model is as follows: The staff places the unfolded document bag sheets one by one into the input end of the directional conveying mechanism 2. The main body of the document bag sheets is pressed and conveyed by the two mating conveying surfaces formed between the sheet conveying assembly 5 and the first limiting conveying assembly 6, and between the auxiliary conveying assembly and the second limiting conveying assembly 7.

[0036] When the document bag sheet moves to the position of the guide conveyor assembly 8 under the drive of the directional conveyor mechanism 2, the back side of the document bag sheet comes into contact with the guide conveyor belt 12 in the guide conveyor assembly 8 and is supported by the guide conveyor belt 12. When the guide conveyor belt 12 moves the document bag sheet to the position of the inclined guide member 13, it will cause the bottom edge of the back side of the document bag sheet to flip upward.

[0037] Subsequently, the outer side of the back portion of the document bag sheet is positioned above and supported by the support portion 11-1 in the folding guide rod 11. Driven by the directional conveying mechanism 2 and the guide conveyor belt 12, the back portion of the document bag sheet gradually passes the folding portion 11-2 of the folding guide rod 11. During this process, as it passes the support portion 11-1 and the folding portion 11-2, it gradually flips from a flat position to a vertical position. The main body of the document bag sheet remains pressed and constrained by the directional conveying mechanism 2. When the back portion of the document bag sheet transitions from the folding portion 11-2 to the pressing portion 11-3, the back portion of the document bag sheet is positioned below the folding guide rod. Constrained by the pressing portion 11-3, the back portion of the document bag sheet is gradually pressed down, completing the initial fold.

[0038] The document bag sheet that has been initially folded is output to the edge pressing output component 4, and is further pressed with the cooperation of the two edge pressing output components 4, the sheet conveying component 5, and the auxiliary conveying component, thereby completing the folding process of the document bag sheet.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
