Description

Technical Field

[0001] This utility model relates to the field of document and book bag making machine technology, and in particular to a feeding structure for document and book bag making machine. Background Technology

[0002] Document and book bag making machines are automated devices specifically designed for producing paper or plastic packaging bags such as document bags, book bags, and file bags. Through a series of mechanical operations (such as feeding, folding, gluing, sealing, and cutting), they transform rolls or sheets of material into finished bags. Widely used in office, education, logistics, and record management fields, the feeding structure is one of the core components of the equipment, primarily responsible for the stable and precise delivery of raw materials (such as rolls of paper, plastic film, or non-woven fabric) to subsequent processing stages (such as printing, folding, and sealing).

[0003] However, the traditional feeding structure used in document bag making machines is relatively simple. During the rotation of the roller, the method of fixing the roll is not flexible enough and lacks certain size adjustment. It cannot adapt to plastic film rolls of different diameters and may not meet diverse production needs.

[0004] For example, in the traditional feeding structure used in document bag making machines, the plastic film roll needs to be rolled to feed the material. During the rolling process, the roll will rotate violently with the roller, and it needs to be simply fixed to prevent the rotation of the roll from affecting the feeding and causing damage to the material. Utility Model Content

[0005] This utility model discloses a feeding structure for a document bag making machine, aiming to solve the technical problem that the traditional feeding structure for document bag making machines is relatively simple in use, and the method of fixing the roll during the rotation of the roller is not flexible enough, lacks certain size adjustment, cannot adapt to plastic film rolls of different diameters, and may not meet the technical needs of diversified production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding structure for a document bag making machine includes a base frame and a roller disposed inside the base frame. An inner shaft body is disposed on the outer circumferential wall of the roller. The structure also includes:

[0008] Adjustment mechanism: The adjustment mechanism includes a fixed frame disposed inside the roller. A second gear is connected to one outer wall of the fixed frame via a bearing. Three arc-shaped grooves are formed on one outer wall of the second gear. Three telescopic plates are also disposed inside the fixed frame. Movable columns are provided on one outer wall of each of the three telescopic plates. The three movable columns are disposed inside the three arc-shaped grooves. A rotating rod is also disposed inside the roller. A first gear is provided on one outer wall of the rotating rod.

[0009] Fixing mechanism: The fixing mechanism is disposed on the inner shaft body;

[0010] Movable mechanism: The movable mechanism is mounted on the base frame.

[0011] In this solution, a fixed frame and a second gear are installed inside the roller, along with three arc-shaped grooves and movable columns on the telescopic plate and the second gear, all installed inside the fixed frame. The rotation of the first gear drives the rotation of the second gear, causing the movable columns to move within the arc-shaped grooves. This controls the extension and retraction of the three telescopic plates connected to the three movable columns, achieving flexible control of the drum fixing structure. The structure can be easily adjusted according to the inner shaft body of different diameters to meet diverse production needs.

[0012] In a preferred embodiment, the fixing mechanism includes a support plate disposed on the outer wall of one side of the three telescopic plates, all three support plates being arc-shaped and fitting against the inner circumferential wall of the inner shaft body.

[0013] By setting an arc-shaped support plate that fits against the inner circumference of the inner shaft body, and a flexible material on the outer wall of the support plate, the inner shaft body can be fixed, preventing the inner shaft body from rotating violently during the feeding process and causing damage to the feeding.

[0014] In a preferred embodiment, the movable mechanism includes a second side frame opened on the top of the base frame. A movable bearing and a movable frame are provided on the bottom outer wall of the second side frame. The two outer walls of the movable bearing are movably connected to the movable frame. A sliding groove is opened on the top outer wall of the base frame, and the movable frame is disposed inside the sliding groove.

[0015] By using the slide groove and the movable frame inside the slide groove, as well as the second side frame and movable bearing on the movable frame, when it is necessary to replace the inner shaft body and the material body, the movable frame can be moved backward to release the roller, and then the second side frame can be turned over for replacement.

An inner shaft body is disposed on the outer circumferential wall of the roller. The structure also includes: an adjustment mechanism: the adjustment mechanism includes a fixed frame disposed inside the roller. A second gear is connected to one outer wall of the fixed frame via a bearing. Three arc-shaped grooves are formed on one outer wall of the second gear. Three telescopic plates are also disposed inside the fixed frame. Movable columns are disposed on one outer wall of each of the three telescopic plates. The three movable columns are disposed within the three arc-shaped grooves. A rotating rod is also disposed inside the roller. A first gear is disposed on one outer wall of the rotating rod. A fixing mechanism: the fixing mechanism is disposed on the inner shaft body. A movable mechanism: the movable mechanism is disposed on the base frame. The feeding structure for a document / book bag making machine provided by this utility model has the technical effect of adding an adjustment mechanism, flexibly adjusting the size, and meeting diverse production needs.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The material feeding structure disclosed in this utility model for a document bag making machine is mainly applied to the traditional material feeding structure for document bag making machines. When in use, the structure is relatively simple, and the method of fixing the roll is not flexible enough during the rotation of the roller. It lacks certain size adjustment and cannot adapt to plastic film rolls of different diameters, which may not meet the diverse production needs of the scenario.

[0024] Reference Figure 1 , Figure 3 and Figure 4 A feeding structure for a document bag making machine includes a base frame 1 and a roller 8 disposed inside the base frame 1. An inner shaft body 9 is disposed on the outer circumferential wall of the roller 8. The machine also includes: an adjustment mechanism: the adjustment mechanism includes a fixed frame 13 disposed inside the roller 8. A second gear 17 is connected to one side of the outer wall of the fixed frame 13 via a bearing. Three arc-shaped grooves are formed on one side of the outer wall of the second gear 17. Three telescopic plates 16 are also disposed inside the fixed frame 13. Movable columns 18 are disposed on one side of the outer wall of each of the three telescopic plates 16. The three movable columns 18 are disposed inside the three arc-shaped grooves. A rotating rod 12 is also disposed inside the roller 8. A first gear 15 is disposed on one side of the outer wall of the rotating rod 12. A fixing mechanism: the fixing mechanism is disposed on the inner shaft body 9. A movable mechanism: the movable mechanism is disposed on the base frame 1.

[0025] The first gear 15 is used in conjunction with the second gear 17, and the second gear 17 is used in conjunction with the three telescopic plates 16.

[0026] Specifically, in this solution, the fixed frame 13 and the second gear 17 set inside the roller 8, as well as the telescopic plate 16 set inside the fixed frame 13, the three arc-shaped grooves on the second gear 17, and the movable column 18 inside, can drive the second gear 17 to rotate in conjunction with the rotation of the first gear 15, so that the movable column 18 can move inside the arc-shaped groove, thereby controlling the extension and retraction of the three telescopic plates 16 connected to the three movable columns 18. This achieves flexible control of the drum fixing structure, and can be easily adjusted according to the inner shaft body 9 of different diameter specifications to meet diverse production needs.

[0027] Reference Figure 1 and Figure 3 In a preferred embodiment, the fixing mechanism includes a support plate 14 disposed on the outer wall of one side of the three telescopic plates 16. The three support plates 14 are all arc-shaped and are in contact with the inner circumferential inner wall of the inner shaft body 9.

[0028] Among them, fixed disks 4 are symmetrically arranged on both sides of the inner shaft body 9. A cylindrical plug is provided on the outer wall of the opposite side of the two fixed disks 4. The two cylindrical plugs are in contact with the inner walls of both sides of the inner shaft body 9. An extension rod is also provided on the outer circumference of the two fixed disks 4. A material body 3 is wound on the outer circumference of the inner shaft body 9. The two extension rods are used in conjunction with the material body 3.

[0029] In practical use, the outer walls of the three support plates 14 are all provided with flexible material (not shown in the figure), which can enhance the fit with the inner circumference of the inner shaft body 9.

[0030] Specifically, by setting an arc-shaped support plate 14 that fits against the inner circumference of the inner shaft body 9, and a flexible material on the outer wall of the support plate 14, the inner shaft body 9 can be fixed to prevent the inner shaft body 9 from rotating violently during the rotation of the roller 8, thus affecting the feeding and causing damage.

[0031] Specifically, the fixing discs 4 on both sides of the inner shaft body 9 and the cylindrical plugs on one side of the fixing frame 13 that match the inner diameter of the inner shaft body 9 can be connected and fixed to the inner shaft body 9. The extension rod on the fixing disc 4 fits against the material body 3 that is wrapped around the circumference of the inner shaft body 9 for simple fixation, preventing the inner shaft body 9 from shaking and the material body 3 from scattering when the roller 8 rotates during the feeding process.

[0032] Reference Figure 1 and Figure 3 In a preferred embodiment, the movable mechanism includes a second side frame 5 opened on the top of the base frame 1. A movable bearing 6 and a movable frame 7 are provided on the bottom outer wall of the second side frame 5. The two outer walls of the movable bearing 6 are movably connected to the movable frame 7. A sliding groove is opened on the top outer wall of the base frame 1, and the movable frame 7 is disposed inside the sliding groove.

[0033] One outer wall of the second side frame 5 is movably connected to the roller 8.

[0034] Specifically, by means of the slide groove set on the top of the base frame 1 and the movable frame 7 inside the slide groove, as well as the second side frame 5 and the movable bearing 6 on the movable frame 7, when it is necessary to replace the inner shaft body 9 and the material body 3, the movable frame 7 can be moved backward to release the roller 8, and then the second side frame 5 can be turned over for replacement.

[0035] Reference Figure 1 and Figure 2 In a preferred embodiment, a first side frame 2 is also provided on the top outer wall of the base frame 1. One side outer wall of the first side frame 2 is movably connected to the roller 8. A square groove is provided on one side outer wall of the first side frame 2. A rotary switch 10 is provided inside the square groove. The rotary switch 10 is connected to the rotating rod 12. A fixing rod 11 is provided inside the rotary switch 10. Six equally spaced round holes are also provided on one side inner wall of the square groove. The fixing rod 11 is used in conjunction with the six round holes.

[0036] Specifically, by using a rotary switch 10 connected to a rotating rod 12 inside the first side frame 2, and a fixing rod 11 inside the rotary switch 10, and in conjunction with a round hole on one side of the square slot, the rotary switch 10 can be rotated to adjust to a suitable position, and the fixing rod 11 can be inserted into the round hole to fix the first gear 15.

[0037] Working principle: In use, first move the movable frame 7 backward to release the roller 8, then turn the second side frame 5 over to place the inner shaft body 9 and the material body 3, then place the two fixed plates 4, and then put the three support plates 14 into the inner shaft body 9. According to the inner diameter of the inner shaft body 9, use the rotary switch 10 to rotate the rotating rod 12, which drives the first gear 15 and the second gear 17 to rotate, so that the movable column 18 moves inside the arc groove, controlling the extension and retraction of the three telescopic plates 16 connected to the three movable columns 18. After adjusting to the appropriate size, insert the fixed rod 11 inside the rotary switch 10 into the round hole opened on one side of the square groove for fixing. Then insert the cylindrical plugs on the two fixed plates 4 into both sides of the inner shaft body 9 for fixing again. After fixing, the material feeding work begins.
