Description

Technical Field

[0001] This utility model relates to the field of sheet drilling technology, specifically to a drilling device for flexible sheets. Background Technology

[0002] Flexible sheets are thin-layer materials with good flexibility that can be folded, bent, and rolled. They are commonly found in various industries, such as fabrics and leather. Flexible sheets need to be customized according to different customer needs before leaving the factory.

[0003] Currently, utility model patent CN212763838U discloses a double-cylinder sheet punching machine, including a worktable, a support plate vertically fixed to the worktable, a crossbeam vertically fixed to the support plate, a first cylinder and a second cylinder fixedly connected to the crossbeam, a punch head fixedly connected to the output shaft of the first cylinder, an installation cavity on the worktable, a limiting component for limiting the sheet material vertically sliding within the installation cavity, and an elastic component for driving the limiting component to reset within the installation cavity. The output shaft of the second cylinder can drive the limiting component to move downwards. This utility model can enhance the stability of the punching machine during the sheet punching process, improve the accuracy of the hole position, and thus improve the punching quality.

[0004] In the prior art, when punching holes in flexible sheets, the punching method described above is mostly used. When it is necessary to change the diameter of the hole, only the punching head needs to be replaced. However, the existing method of changing the punching head to change the diameter of the hole is still cumbersome in actual operation and requires stopping the machine. In order to enable the punching device to directly open through holes of different diameters, this application provides a punching device for flexible sheets to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a punching device for flexible sheets to solve the problem in the prior art that it is inconvenient to directly open through holes of different diameters when punching flexible sheets.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A punching device for flexible sheet material includes a housing and a positioning platform for adsorbing and positioning the flexible sheet material, wherein the positioning platform is disposed on the top of the housing. It also includes an X-axis moving mechanism mounted on the housing, a Y-axis moving mechanism that can be driven to perform linear motion, and a punching module that can be driven to perform linear motion. The X-axis moving mechanism is located outside the positioning platform, and the Y-axis moving mechanism is located above the positioning platform; The punching module includes a reciprocating drive, a small motor, and a punching tool. The output shaft of the reciprocating drive is connected to the small motor, and the punching tool is mounted on the output shaft of the small motor.

[0007] Through the above technical solution, the driving method mainly based on the X-axis moving mechanism and the Y-axis moving mechanism can drive the punching module to move at any point on the plane, and thus the punching module can be used to perform hole processing of any diameter on the flexible sheet.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the X-axis moving mechanism includes two support plates disposed inside the housing, the support plates are provided with X-axis slide rails, and X-axis sliders are slidably connected on the X-axis slide rails; The support plate is rotatably connected to two support shafts via bearings. A synchronous pulley is sleeved on the outer side of the support shaft. A synchronous belt is engaged between the outer sides of the two synchronous pulleys on the same support plate. The outer side of the synchronous belt is connected to the corresponding X-axis slider. The X-axis slider is located between the two opposite sides of the synchronous belts.

[0010] Through the above technical solution, the synchronous belt can be driven by the two corresponding synchronous pulleys, thereby driving the X-axis slider to move on the outside of the corresponding X-axis slide rail.

[0011] Furthermore, the bottom end of the first support shaft penetrates through the corresponding support plate, and a driven bevel gear is sleeved on the outer side of the first support shaft on the left side, with the driven bevel gear located below the support plate; The housing is rotatably connected to a connecting shaft via bearings. The connecting shaft is located below the driven bevel gear, and two driving bevel gears are sleeved on the outside of the connecting shaft. A servo motor is located outside the housing.

[0012] Through the above technical solution, the connecting shaft can drive the driving bevel gear to rotate below the driven bevel gear.

[0013] Furthermore, the two driving bevel gears mesh with the outer sides of the two driven bevel gears respectively, and the two driving bevel gears are located between the opposite sides of the two driven bevel gears and are symmetrically distributed; The output shaft of the servo motor passes through the outside of the housing and is fixed to the end of the connecting shaft.

[0014] The above technical solution enables the servo motor to drive the connecting shaft to rotate; the two active bevel gears can drive the two driven bevel gears to rotate respectively.

[0015] Furthermore, the Y-axis moving mechanism includes a support frame mounted on the X-axis slider. The support frame has a support shell on its outer side and an inner plate inside the support shell. A second support shaft is rotatably connected to the inner plate via a bearing. A second servo motor is mounted at the bottom of one of the inner plates. The output shaft of the second servo motor passes through the corresponding inner plate and is connected to the end of the corresponding second support shaft. A second synchronous wheel is mounted on the outer side of the second support shaft.

[0016] The above technical solutions enable the support shell and inner panel to provide space for structural installation.

[0017] Furthermore, a synchronous belt is engaged between the outer sides of the two synchronous pulleys, and a crossbeam is provided between the opposite sides of the two inner plates, with two Y-axis slide rails on the crossbeam.

[0018] The above technical solution enables the synchronous belt 2 to be driven by the two synchronous pulleys 2 for transmission.

[0019] Furthermore, the punching module includes a housing, a fixing frame inside the housing, two Y-axis sliders at the bottom of the fixing frame, the two Y-axis sliders being slidably connected to the outside of two Y-axis slide rails respectively, and a fixing plate on the outside of the fixing frame being connected to the outside of the second synchronous belt.

[0020] The above technical solution enables the synchronous belt to drive the fixed plate to move synchronously during the second transmission, thereby driving the Y-axis slider to move on the outside of the corresponding Y-axis slide rail.

[0021] Furthermore, the reciprocating drive component is mounted on a fixed frame, and a through hole is provided at the bottom of the equipment housing for the punch to extend out.

[0022] The above technical solution uses a reciprocating drive component to drive a punch to perform reciprocating cutting motions.

[0023] Furthermore, the bottom end of the punch is conical, the punch has a sheet-like structure, and one side of the punch is the cutting edge.

[0024] The above technical solution allows the punch to easily pierce the flexible sheet material through its conical shape, while the sheet-like structure controls the friction of the punch during cutting, enabling it to perform smooth circumferential cutting.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. Through the cooperation of the X-axis and Y-axis moving mechanisms, the punching module can be driven to move to different positions in the plane, thereby completing circumferential motion of different diameters; through the cooperation of the reciprocating drive and the punching blade, the flexible sheet can be punctured and cut during circumferential motion of different diameters, thus meeting the opening requirements of different diameters and facilitating efficient and convenient processing. 2. By setting a punch that can be adjusted at multiple angles, it can cut the surrounding flexible sheet material normally when it is moving in a circular motion, so as to meet the cutting and opening requirements of the flexible sheet material.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] Example: Reference Figure 1 A punching device for flexible sheet material includes a housing 1 and a positioning platform 2 for adsorbing and positioning the flexible sheet material, the positioning platform 2 being disposed on the top of the housing 1; it also includes an X-axis moving mechanism 3 disposed on the housing 1, a Y-axis moving mechanism 4 disposed on the X-axis moving mechanism 3 and a punching module 5 disposed on the Y-axis moving mechanism 4 and a punching module 5 disposed on the Y-axis moving mechanism 4; the X-axis moving mechanism 3 is located outside the positioning platform 2, and the Y-axis moving mechanism 4 is located above the positioning platform 2; the punching module 5 includes a reciprocating drive 54, a small motor 56 and a punching cutter 55, the output shaft of the reciprocating drive 54 being connected to the small motor 56, and the punching cutter 55 being disposed on the output shaft of the small motor 56.

[0031] It should be noted that flexible sheets can be sheet-like flexible materials such as leather, denim, jersey fabric, and quilting.

[0032] refer to Figure 4 and Figure 5 The X-axis moving mechanism 3 includes two support plates 31 disposed inside the housing 1. An X-axis slide rail 32 is provided on the support plate 31, and an X-axis slider 33 is slidably connected to the X-axis slide rail 32. Two support shafts 34 are rotatably connected to the support plate 31 through bearings. Synchronous pulleys 35 are sleeved on the outer side of the support shafts 34. A synchronous belt 36 meshes between the outer sides of the two synchronous pulleys 35 on the same support plate 31. The outer side of the synchronous belt 36 is connected to the corresponding X-axis slider 33. The X-axis slider 33 is located between the two opposite sides of the two synchronous belts 36, so that the synchronous belt 36 can be driven by the two corresponding synchronous pulleys 35 to perform transmission, thereby driving the X-axis slider 33 to move on the outer side of the corresponding X-axis slide rail 32.

[0033] refer to Figure 5 and Figure 6The bottom end of the support shaft 34 passes through the corresponding support plate 31. A driven bevel gear 37 is sleeved on the outside of the support shaft 34 on the left side. The driven bevel gear 37 is located below the support plate 31. A connecting shaft 38 is rotatably connected to the housing 1 through a bearing. The connecting shaft 38 is located below the driven bevel gear 37, so that the connecting shaft 38 can drive the driving bevel gear 39 to rotate below the driven bevel gear 37.

[0034] refer to Figure 5 and Figure 6 Two active bevel gears 39 are sleeved on the outside of the connecting shaft 38, and a servo motor 310 is provided outside the housing 1. The two active bevel gears 39 mesh with the outer sides of the two driven bevel gears 37 respectively, so that the two active bevel gears 39 can drive the two driven bevel gears 37 to rotate respectively. The output shaft of the servo motor 310 passes through the outside of the housing 1 and is fixed to the end of the connecting shaft 38, so that the servo motor 310 can drive the connecting shaft 38 to rotate.

[0035] refer to Figure 5 and Figure 6 The two driving bevel gears 39 are located between the two driven bevel gears 37 on opposite sides and are symmetrically distributed, so that the two driving bevel gears 39 can drive the two driven bevel gears 37 to rotate in opposite directions. This makes the transmission directions of the two synchronous belts 36 on opposite sides the same, so that the two X-axis sliders 33 can be driven to move synchronously on the corresponding X-axis slide rails 32.

[0036] In use, the servo motor 310 drives the connecting shaft 38 to rotate, causing the two active bevel gears 39 to rotate and drive the two driven bevel gears 37 to rotate in opposite directions. This causes the synchronous pulleys 35 and synchronous belts 36 on both sides to rotate in opposite directions, thereby driving the two symmetrically arranged X-axis sliders 33 to slide on the corresponding X-axis slide rails 32.

[0037] refer to Figure 2 and Figure 4 The Y-axis moving mechanism 4 includes a support frame 41 mounted on the X-axis slider 33. When the X-axis slider 33 moves, it can drive the Y-axis moving mechanism 4 to move. The support frame 41 has a support shell 42 on its outer side and an inner plate 421 inside the support shell 42, so that the support shell 42 and the inner plate 421 can provide space for structural installation.

[0038] refer to Figure 2A second support shaft 43 is rotatably connected to the inner plate 421 via bearings. A second servo motor is located at the bottom of one of the inner plates 421. The output shaft of the second servo motor passes through the corresponding inner plate 421 and is connected to the end of the corresponding second support shaft 43. A second synchronous pulley 44 is sleeved on the outer side of the second support shaft 43. A second synchronous belt 45 meshes between the outer sides of the two second synchronous pulleys 44, so that the second servo motor can drive the corresponding second support shaft 43 to rotate. Then, through the transmission of the second synchronous belt 45, the two second synchronous pulleys 44 rotate synchronously, so as to achieve stable transmission of the second synchronous belt 45.

[0039] refer to Figure 2 and Figure 3 A crossbeam 46 is provided between the two inner plates 421 on opposite sides. Two Y-axis slide rails 47 are provided on the crossbeam 46. The drilling module 5 includes a housing 51. A fixing frame 52 is provided inside the housing 51. Two Y-axis sliders 53 are provided at the bottom of the fixing frame 52. The two Y-axis sliders 53 are slidably connected to the outside of the two Y-axis slide rails 47 respectively. A fixing plate 48 is provided on the outside of the fixing frame 52. The fixing plate 48 is connected to the outside of the second synchronous belt 45, so that the second synchronous belt 45 can drive the fixing plate 48 to move synchronously during transmission, thereby driving the Y-axis sliders 53 to move on the outside of the corresponding Y-axis slide rails 47.

[0040] refer to Figure 3 The reciprocating drive 54 is mounted on the fixed frame 52. The bottom of the equipment housing 51 has a through hole for the punch 55 to extend. The reciprocating drive 54 drives the small motor 56 and the punch 55 to perform reciprocating cutting action. The small motor 56 is equipped with an encoder. Through the control of the encoder, the small motor 56 can be adjusted in angle according to a specified preset path.

[0041] It should be noted that the reciprocating drive 54 can be a crank-connecting rod mechanism, driven by a motor, which can convert rotational motion into linear motion, thereby driving the punch 55 to perform linear cutting. Reciprocating drive equipment is commonly used in existing industrial technology. Any equipment that can meet the requirements of linear reciprocating drive can be used, so it will not be described in detail.

[0042] refer to Figure 3 The bottom of the punch 55 is tapered. The tapered design allows the punch to easily pierce the flexible sheet. The punch 55 has a sheet-like structure with one side being the cutting edge. The sheet-like structure can control the friction of the punch during cutting, enabling it to perform smooth circumferential cutting.

[0043] In use, the X-axis moving mechanism 3 and the Y-axis moving mechanism 4 drive the fixed frame to move in a ring with any diameter. The reciprocating drive component 54 drives the small motor 56 and the punch 55 to move up and down in a reciprocating motion, so that the punch 55 can pierce and enter the flexible sheet. Through the control of the small motor 56, the blade surface of the punch 55 can be matched with the cutting surface, so as to complete the ring cutting action.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
