Description

Technical Field

[0001] This utility model relates to the field of luggage processing equipment technology, and in particular to a cutting device for producing travel luggage. Background Technology

[0002] Travel bags have become an essential item for travel. Their production involves multiple processes such as blow molding, fabric cutting, sewing, and assembly. Edge trimming is a key post-processing step that determines the neatness of the appearance, assembly accuracy, and yield rate. It is mainly used to remove burrs from the shell molding, excess fabric, and rough edges from splicing seams, ensuring uniform dimensions, smooth edges, and easy assembly of components such as pull rods, wheel seats, and corner protectors.

[0003] Most common edge trimming equipment consists of a linear guide rail and a circular synchronous cutting mechanism. The bag shell is fed along the fixed linear guide rail, and the cutting blade moves in a closed loop with the guide rail, completing the edge trimming in one pass without the need for manual adjustment.

[0004] However, during the cutting process, when the bag is attached to the support frame on the guide rail, external clamping can easily cause deformation and displacement of the shell. Without external clamping, the edges are prone to warping during cutting, which affects the processing quality. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the prior art. However, in the cutting process, when the bag is attached to the support frame on the guide rail, the external clamping can easily cause the shell to deform and shift. Without external clamping, the edge is easy to curl during the cutting process, which affects the processing quality. Therefore, a cutting device for the production of travel bags is proposed.

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

[0007] A cutting device for producing travel bags, comprising:

[0008] A frame and a guide rail, wherein the guide rail is mounted on the frame, a mounting plate is slidably connected to the guide rail, a support box is fixedly connected to the mounting plate, and multiple through holes are provided on the upper surface of the support box;

[0009] Multiple fixing components and square boxes are provided. The square boxes are fixedly connected to the upper surface of the mounting plate and are located below the through holes.

[0010] Preferably, a rotating shaft is rotatably connected to the square box, and horizontal plates are fixedly connected to both ends of the rotating shaft. A sliding groove is provided on the horizontal plate, and a slider is slidably connected in the sliding groove. A support rod is rotatably connected to the slider.

[0011] Preferably, the fixing component includes a suction cup, a cylinder, a metal block, and an electromagnetic block. The cylinder is rotatably connected between two support rods. The suction cup is fixedly connected to the upper end of the cylinder. The metal block is fixedly connected to the end of the cylinder away from the suction cup. The electromagnetic block is fixedly connected to the mounting plate and is disposed on the lower side of the metal block.

[0012] Preferably, a cam is fixedly connected to the rotating shaft, the cam is disposed inside a square box, and a movable plate is slidably connected inside the square box. The movable plate is hinged to the end of the cam away from the rotating shaft.

[0013] Preferably, a pull plate is slidably connected inside the square box, and a second spring is fixedly connected between the pull plate and the movable plate.

[0014] Preferably, an airbag is fixedly connected to the bottom wall of the square box, the upper end of the airbag is fixedly connected to the pull plate, and a connecting pipe is fixedly connected between the airbag and the cylinder.

[0015] Preferably, a fixing block is fixedly connected to one side of the square box. The fixing block is T-shaped. Protrusions are provided at both ends of the rotating shaft. A first spring is fixedly connected between each end of the fixing block and the protrusion.

[0016] Preferably, a cutter is mounted on the frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses multiple suction cups to adsorb and fix the inner wall of the bag shell, eliminating the need for external clamps to clamp the bag from the outside. This avoids the problem of deformation of the bag shell during clamping and firmly attaches the four corners of the bag shell to the surface of the support box. It effectively solves the problem of edge warping and displacement during edge cutting, ensuring the accuracy and yield of edge cutting processing.

[0019] 2. After processing is completed and the structure is reset, the cylinder and suction cup move upward to push the processed bag shell upward to a certain height, making it easy to remove the processed bag. The operation is convenient and the fixation is stable, which can effectively prevent the bag edge from curling or shifting during the cutting process, thus improving the accuracy and quality of the cutting process.

[0028] Reference Figure 1 A cutting device for producing travel bags, comprising:

[0029] The frame 1 and guide rail 6 are mounted on the frame 1. A mounting plate 3 is slidably connected to the guide rail 6. The guide rail 6 is a linear guide rail, and the mounting plate 3 is a block. The guide rail 6 is a common type of guide rail, suitable for: edge trimming machine tool holders, movable machine heads, and lateral movement assemblies. A support box 5 is fixedly connected to the mounting plate 3. The upper surface of the support box 5 has multiple through holes. A cutter 2 is mounted on the frame 1. The cutter 2 is controlled by a CNC system and moves along the trajectory of the outer contour of the bag, thereby achieving the cutting effect on the edge of the bag shell.

[0030] Reference Figures 2-4 Multiple fixed components and square boxes 9, cam 19, moving plate 20, pull plate 21, airbag 14 and other structures are installed in the square boxes 9. Multiple square boxes 9 are fixedly connected to the upper surface of the mounting plate 3 and are located below the through holes. Multiple through holes are respectively set at the four corners of the support box 5, so as to attract the four corners of the bag shell and prevent the bag shell from warping when cutting. A rotating shaft 15 is rotatably connected to the square box 9. A horizontal plate 10 is fixedly connected to both ends of the rotating shaft 15. A sliding groove is opened on the horizontal plate 10. A slider 11 is slidably connected in the sliding groove. A support rod 18 is rotatably connected to the slider 11. The support rod 18 is rotatably connected to the cylinder 7. Therefore, when the horizontal plate 10 moves in a fan shape, it does not affect the vertical downward movement of the cylinder 7.

[0031] Reference Figures 2-3 Multiple fixing components are installed on one side of the square box 9. The fixing components include a suction cup 4, a cylinder 7, a metal block 13, and an electromagnetic block 8. The cylinder 7 is rotatably connected between two support rods 18. The suction cup 4 is fixedly connected to the upper end of the cylinder 7. When the outer shell of the bag is placed on the suction cup 4, the suction cup 4 can adsorb the inner wall of the outer shell of the bag. The metal block 13 is fixedly connected to the end of the cylinder 7 away from the suction cup 4. The electromagnetic block 8 is fixedly connected to the mounting plate 3 and is located on the lower side of the metal block 13. The fixing components are used to fix the bag placed on the support box 5.

[0032] Reference Figures 3-4A cam 19 is fixedly connected to the rotating shaft 15. The cam 19 is located inside the square box 9. A movable plate 20 is slidably connected inside the square box 9. The movable plate 20 is hinged to the end of the cam 19 away from the rotating shaft 15. A pull plate 21 is slidably connected inside the square box 9. A second spring 22 is fixedly connected between the pull plate 21 and the movable plate 20. An airbag 14 is fixedly connected to the bottom wall of the square box 9. The upper end of the airbag 14 is fixedly connected to the pull plate 21. A connecting pipe 12 is fixedly connected between the airbag 14 and the cylinder 7. When the movable plate 20 moves upward, the pull plate 21 is pulled upward by the second spring 22, thereby stretching the airbag 14. The second spring 22 is used to stretch the airbag 14, which is not a hard pull, so as to avoid damage to the airbag 14 due to excessive force. A fixing block 16 is fixedly connected to one side of the square box 9. The fixing block 16 is T-shaped. Protrusions are provided at both ends of the rotating shaft 15. A first spring 17 is fixedly connected between the two ends of the fixing block 16 and the protrusions.

[0033] In this invention, the suitcase shell is first placed upside down on the support box 5. At this time, the inside of the shell is not in contact with the outer surface of the support box 5, but is supported and attracted by the suction cup 4, which is higher than the support box 5. Then, the electromagnetic block 8 is driven. After the electromagnetic block 8 is energized, it generates an attraction force on the metal block 13, which can attract the metal block 13 and the cylinder 7 to move down. After the cylinder 7 moves down, it drives the horizontal plate 10 to rotate around the pivot 15, and stretches the first spring 17. When the horizontal plate 10 rotates, the slider 11 slides in the groove, and at the same time pushes the support rod 18 to rotate, so that the cylinder 7 can move vertically downward. At this time, the pivot 15 rotates with the rotation of the horizontal plate 10. When the pivot 15 rotates, it drives the cam 19 to rotate. The rotation of the cam 19 pulls the moving plate 20 inside the square box 9. Sliding upwards, the moving plate 20 pulls the pull plate 21 upwards via the second spring 22. After the pull plate 21 moves upwards, it stretches the airbag 14. The airbag 14 expands and generates negative pressure. Through the connecting pipe 12, the air in the cylinder 7 and the suction cup 4 is drawn into the airbag 14, so that negative pressure is formed inside the suction cup 4. This firmly adsorbs and fixes the bag shell that is in contact with the suction cup 4 onto the multiple suction cups 4, without the need for external clamps to clamp from the outside of the bag, thus avoiding the bag shell being clamped and deformed. During the process of the suction cup 4 moving downwards into the through hole, it can pull the bag shell downwards to fit against the outer surface of the support box 5, ensuring the stability of the adhesion and adsorption. Then, the mounting plate 3 slides horizontally on the guide rail 6, which, together with the closed-loop movement of the cutter 2, achieves a stable cutting effect on the edge of the bag shell.

[0034] After the edge trimming is completed, the power supply to the electromagnetic block 8 is disconnected, and the attraction force of the electromagnetic block 8 on the metal block 13 disappears. The first spring 17 elastically resets and pulls the rotating shaft 15 and the horizontal plate 10 to reset. The cam 19 rotates in the opposite direction and pushes the moving plate 20 down. The pull plate 21 moves down and squeezes the airbag 14, forcing the air in the airbag 14 back into the suction cup 4. The negative pressure disappears, and at the same time, the cylinder 7 and the suction cup 4 move up, which can push the processed bag shell upward to a certain height. The processed bag can then be easily removed. The operation is convenient and the fixation is stable. It can effectively prevent the edges of the bag from curling or shifting during the edge trimming process, and improve the accuracy and quality of the edge trimming.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
