Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, and more specifically, to an automatic cutting machine with an adjustable cutting angle. Background Technology

[0002] Carbon fiber has been increasingly widely used due to its superior properties. When molding carbon fiber products, the product shape is typically pre-formed using carbon fiber prepreg, and then the pre-formed semi-finished product is placed in a corresponding mold and heated and pressed to form the final product. Carbon fiber prepreg is usually wound into rolls for easy transportation and storage. When using pre-formed products from carbon fiber prepreg, the prepreg in the roll needs to be unwound and cut into larger sheets for later cutting into smaller pieces as needed. Carbon fiber prepreg is cut using a cutting machine, but existing cutting machines cannot adjust the cutting angle, failing to meet the cutting requirements of different angles and shapes.

[0003] In view of this, the inventors of this application have invented an automatic cutting machine with an adjustable cutting angle. Summary of the Invention

The rubber wheels are located on the fixed conveying seat and the sliding conveying seat. The working platform is provided with a conveying shaft that extends to the left and right. The conveying rope of the conveying assembly passes around the conveying shaft. The rotation of the conveying shaft drives the conveying rope to move.

[0014] Furthermore, the working platform is provided with a limiting slide rail arranged in the front-to-back direction and a limiting slider that slides with the limiting slide rail.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0052] It should be noted that in this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element of this invention must have a specific orientation, and therefore should not be construed as a limitation of this invention. Example

[0053] Cooperate Figures 1 to 9 As shown, this invention discloses an automatic cutting machine with an adjustable cutting angle, mainly used for cutting carbon fiber prepreg fabric into the required shapes and sizes. Its cutting angle is adjustable, allowing it to cut carbon fiber yarn sheets of different shapes, such as rectangles, parallelograms (non-rectangular), trapezoids, etc. Furthermore, the interior angles of each shape are adjustable, thus meeting the needs for carbon fiber yarn sheets of different shapes. Of course, this cutting machine can also be used to cut other suitable roll materials, and this is not a limitation.

[0054] Cooperate Figures 1 to 9 As shown, an automatic cutting machine with an adjustable cutting angle includes:

[0055] The feeding mechanism 10 includes a feeding seat 11 and a conveying roller group 14. The feeding seat 11 holds a material roll 50, and the conveying roller group 14 is located behind the material roll 50. The conveying roller group 14 rotates to output the material 52 on the material roll 50 to the rear.

[0056] The conveying mechanism 20 includes a working platform 21, which is located behind the conveying roller group 14. The working platform 21 is provided with a conveying component 22 for conveying the material 52 to the rear of the working platform 21.

[0057] Angle adjustment mechanism 30 includes a rotary seat 31 rotatably connected to the working platform 21 and a rotary drive assembly 32 that drives the rotary seat 31 to rotate.

[0058] The cutting mechanism 40 is mounted on the rotating seat 31. The cutting mechanism 40 includes a lifting knife seat 41, a cutting knife 42 mounted on the lifting knife seat 41, and a transverse drive assembly 43 that drives the cutting knife 42 to move left and right.

[0059] Of course, the cutting machine also includes a control system that controls the automatic operation of the entire equipment, but this part is not the focus of this application and will not be described in detail here.

[0060] Cooperate Figures 1 to 4As shown, the material roll 50 includes a central roller 51 and material 52 (carbon fiber prepreg or other suitable material) wound on the roller 51. The feeding mechanism 10 is used to place the material roll 50 and unfold and send out the material 52. The conveying mechanism 20, the angle adjustment mechanism 30, and the cutting mechanism 40 constitute a cutting angle adjustment device, which realizes the cutting of the material 52 and can adjust the cutting angle according to the needs.

[0061] The material roll 50 is placed on the feeding seat 11. The material 52 in the material roll 50 is output to the rear (conveying mechanism 20) by the rotation of the conveying roller group 14. The conveying mechanism 20 continues to output the material 52 to the cutting mechanism 40. The cutting mechanism 40 drives the cutting blade 42 to move left and right (lateral movement) to cut the material 52. The conveying mechanism 20 continues to convey the cut material 52 to the rear of the working platform 21 (a collection device for collecting the cut material 52 can be designed at the rear of the working platform 21). When it is necessary to cut materials 52 of different shapes and angles, the rotating seat 31 drives the cutting mechanism 40 to rotate to the required angle. Then the cutting mechanism 40 cuts to obtain the material 52 of the required shape.

[0062] The feeding mechanism 10 includes a frame, a feeding seat 11 and a conveying roller assembly 14, both mounted on the frame. The feeding seat 11 is located at the front end of the frame. The feeding seat 11 includes a base 111, a left fixed seat 112 and a right fixed seat 113 that respectively fix the left and right ends of the material roll 50. The left fixed seat 112 and the right fixed seat 113 are both mounted on the base 111. The roll 51 is rotatably fixed between the left fixed seat 112 and the right fixed seat 113. When the material 52 is output, the roll 51 rotates between the left fixed seat 112 and the right fixed seat 113. Specifically, the spool 51 is hollow at both ends, and the inner sides of the left fixing seat 112 and the right fixing seat 113 are respectively provided with a fixing boss 115. The fixing boss 115 is respectively engaged with the two ends of the spool 51 to fix the material roll 50. The maximum outer diameter of the fixing boss 115 is smaller than the inner diameter of the end of the spool 51. The spool 51 can rotate relative to the fixing boss 115.

[0063] The feeding seat 11 is equipped with a width adjustment component 12 for adjusting the distance between the left fixed seat 112 and the right fixed seat 113, and a left-right adjustment component 13 for adjusting the left and right positions of the material roll 50. By setting the width adjustment component 12 and the left-right adjustment component 13, the loading and unloading of the material roll 50 becomes more flexible and convenient. In order to adapt to the width adjustment component 12 and the left-right adjustment component 13, the left fixed seat 112 and the right fixed seat 113 are both slidably engaged with the base 111 to achieve the above-mentioned functions of width adjustment and left-right position adjustment.

[0064] Cooperate Figures 2 to 4As shown, by setting the width adjustment component 12, the distance between the left fixing seat 112 and the right fixing seat 113 can be adjusted, which makes it easy to place the material roll 50 between the left fixing seat 112 and the right fixing seat 113 for fixing, and to take the empty roll 51 out from the left fixing seat 112 and the right fixing seat 113. In addition, the adjustable distance between the left fixing seat 112 and the right fixing seat 113 also makes it suitable for rolls 51 of different lengths, and thus also suitable for material rolls 50 of different widths, making it flexible and convenient to use.

[0065] An adjusting seat 114 is provided on the base 111. The adjusting seat 114 is located between the left fixed seat 112 and the right fixed seat 113. The width adjusting assembly 12 includes a width adjusting screw 121 that rotates with the adjusting seat 114. The width adjusting screw 121 includes a left helical segment 122 that rotates with the left fixed seat 112 and a right helical segment 123 that rotates with the right fixed seat 113 (the left helical segment 122 is on the left side of the adjusting seat 114, and the right helical segment 123 is on the right side of the adjusting seat 114). The helical directions of the threads of the left helical segment 122 and the right helical segment 123 are opposite.

[0066] At least one end of the width adjusting screw 121 is provided with an adjusting handle (not shown in the figure). Rotating the adjusting handle in both directions causes the width adjusting screw 121 to rotate in both directions relative to the adjusting seat 114, thereby causing the left fixed seat 112 and the right fixed seat 113 to move towards each other, thus reducing the distance between them; or causing the left fixed seat 112 and the right fixed seat 113 to move away from each other, thus increasing the distance between them.

[0067] By setting the left and right adjustment component 13, the left and right positions of the left fixed seat 112 and the right fixed seat 113 on the base 111 can be adjusted, thereby changing the left and right position of the material roll 50 as it enters the subsequent rear conveyor roller group 14.

[0068] The adjusting seat 114 is slidably engaged with the base 111. The left and right adjusting assembly 13 includes a left and right adjusting screw 131, a left and right adjusting nut 132 that engages with the left and right adjusting screw 131, and a left and right adjusting motor 133 that drives the left and right adjusting screw 131 to rotate. The left and right adjusting screw 131 extends left and right, and the left and right adjusting nut 132 is fixedly connected to the adjusting seat 114.

[0069] The left and right adjustment motor 133 drives the left and right adjustment screw 131 to rotate, which in turn drives the left and right adjustment nut 132 to move left and right, thereby causing the adjustment seat 114, width adjustment screw 121, left fixed seat 112, and right fixed seat 113 to slide left and right relative to the base 111.

[0070] Cooperate Figures 2 to 3As shown, the conveyor roller assembly 14 is mounted on the frame and located behind the feeding seat 11. The conveyor roller assembly 14 rotates to push the material 52 on the material roll 50 backward (output onto the working platform 21). The conveyor roller assembly 14 includes a feeding roller 141, a guide roller 142, and a pressure regulating roller arranged sequentially from front to back. The material 52 passes through the feeding roller 141, the guide roller 142, and the pressure regulating roller in sequence and is output backward. The feeding roller 141 and the guide roller 142 ensure that the material 52 is effectively output under a certain tension, and the pressure regulating roller can further adjust the pressure of the material 52 when it is output, ensuring the effective and accurate output of the material 52.

[0071] The pressure regulating roller includes an upper regulating roller 143 and a lower conveying roller 144 located below the upper regulating roller 143. The upper regulating roller 143 is mounted on a lifting base 145, which is connected to a lifting drive unit for driving its lifting and lowering. The lifting drive unit is preferably an electric cylinder. The lifting drive unit drives the upper regulating roller 143 to move up and down, thereby adjusting the distance between the upper regulating roller 143 and the lower conveying roller 144, thus adjusting the pressure on the material 52 between the upper regulating roller 143 and the lower conveying roller 144.

[0072] In addition, a tension roller 146 is provided between the feeding roller 141 and the guide roller 142. The material 52 passes sequentially below the feeding roller 141, above the tension roller 146, and above the guide roller 142 before entering the pressure regulating roller. The tension roller 146 further ensures the tension of the material 52. The material 52 output from the guide roller 142 enters between the upper regulating roller 143 and the lower conveying roller 144 and is output backward. The lower conveying roller 144 is connected to a motor that drives its rotation.

[0073] The feeding mechanism 10 also includes a receiving assembly 15 located behind the feeding seat 11. The receiving assembly 15 includes a receiving shaft 151 and a receiving motor 152 that drives the receiving shaft 151 to rotate. Carbon fiber prepreg is usually wound with a layer of anti-stick film attached. When cutting the carbon fiber prepreg, sometimes this anti-stick film needs to be removed directly. Therefore, the receiving assembly 15 was designed to wind and recycle the anti-stick film. Of course, when the anti-stick film does not need to be removed, or for some materials 52 without an anti-stick film, the receiving assembly 15 may not be used during equipment operation. The receiving assembly 15 is located at the front end of the frame and above the conveyor roller group 14. The receiving motor 152 drives the receiving shaft 151 to rotate and wind and recycle the anti-stick film.

[0074] Cooperate Figure 1 , Figure 5As shown, the working platform 21 is located at the rear of the frame. The material 52 output by the conveying assembly 22 and the conveying roller group 14 is conveyed from the front end of the working platform 21 to the rear end of the working platform 21. The angle adjustment mechanism 30 and the cutting mechanism 40 are located in the middle of the working platform 21 to realize the cutting of the material 52 and the adjustment of the cutting angle.

[0075] Cooperate Figures 5 to 8 As shown, the angle adjustment mechanism 30 includes a rotating seat 31 located above the middle of the working platform 21. The middle part of the rotating seat 31 is rotatably connected to the working platform 21 via a rotating shaft 312. The rotation drive assembly 32 drives the rotating seat 31 to rotate horizontally relative to the working platform 21 via the rotating shaft 312.

[0076] The rotary drive assembly 32 includes an angle adjusting screw 321, an angle adjusting nut 322 cooperating with the angle adjusting screw 321, and an angle adjusting motor 323 driving the angle adjusting screw 321 to rotate. The angle adjusting screw 321 extends from front to back, and the angle adjusting nut 322 is rotatably connected to the rotary seat 31. The angle adjusting nut 322 is rotatably connected to the bottom surface of the left or right end of the rotary seat 31. The angle adjusting motor 323 drives the angle adjusting screw 321 to rotate, thereby driving the angle adjusting nut 322 to move back and forth relative to the angle adjusting screw 321, and thus driving the rotary seat 31 to rotate relative to the working platform 21.

[0077] The working platform 21 is provided with a front-to-back limiting slide rail 23 and a limiting slider 231 that slides with the limiting slide rail 23. The limiting slider 231 is connected to the rotating seat 31 through a connecting shaft 232, and the connecting shaft 232 is slidably connected to the rotating seat 31 through a connecting slider 233 (the connecting slider 233 can slide left and right relative to the rotating seat 31).

[0078] The bottom surfaces at both ends of the rotating base 31 are equipped with the aforementioned connecting shaft 232, limiting slider 231, and limiting slide rail 23. When the rotation drive assembly 32 drives the rotating base 31 to rotate, the rotating base 31 can rotate relative to the connecting shaft 232, while the connecting shaft 232 can slide left and right (laterally) relative to the rotating base 31 to ensure that the rotating base 31 can rotate smoothly. In addition, to make the structural design simpler and more compact, the angle adjusting nut 322 is fixedly connected to one of the limiting sliders 231.

[0079] When the movement trajectory of the cutting blade 42 is perpendicular to the material conveying direction (from front to back), the cutting angle is 0 degrees. The angle at which the rotating seat 31 rotates relative to the working platform 21 is the cutting angle. In this embodiment, the cutting angle is specifically 0-40 degrees. The actual cutting angle can be flexibly adjusted within this range according to the requirements.

[0080] Cooperate Figure 7 As shown, the rotating seat 31 has a cutting platform 311, and the cutting mechanism 40 is disposed on the cutting platform 311. The material 52 passes through the cutting platform 311 and is cut by the cutting mechanism 40 on the cutting platform 311. The cutting mechanism 40 rotates with the rotating seat 31 (the material 52 does not rotate), thereby realizing the adjustment of the cutting angle. Among them, the width of the cutting platform 311 and the cutting stroke of the cutting blade 42 need to be designed to be large, greater than the width of the material 52 to be cut, so that the material 52 can be successfully cut when the rotating seat 31 (cutting platform 311) rotates to different angles.

[0081] The lifting blade holder 41 is vertically mounted on the cutting platform 311. A lifting motor is installed on the rotating base 31 to drive the lifting blade holder 41 up and down. The bottom surface of the cutting blade 42 is flat; when it moves downwards to abut against the cutting platform 311, it can press the material 52 firmly onto the cutting platform 311. The cutting blade 42 is located on the rear side of the lifting blade holder 41, and its position is lower than the bottom surface of the lifting blade holder 41. The cutting platform 311 has left-right extending clearance grooves 313 corresponding to the position of the cutting blade 42. When the cutting blade 42 moves left and right to cut, it extends into the clearance grooves 313.

[0082] The transverse drive assembly 43 includes a timing belt that moves laterally left and right, a cutting blade plate fixed on the timing belt, and a cutting blade 42 fixed on the cutting blade plate. The timing belt drives the cutting blade plate and the cutting blade 42 to reciprocate left and right.

[0083] The conveying assembly 22 conveys the material 52 before cutting to the cutting platform 311, and conveys the material 52 after cutting from the position of the cutting platform 311 to the rear of the working platform 21. At the same time, it must ensure that the material 52 is effectively conveyed before and after cutting when the rotating seat 31 rotates to different positions.

[0084] The working platform 21 is equipped with a guide rail 24 arranged in the front-to-back direction and a guide slider 241 that slides in cooperation with the guide rail 24. The rotation of the rotating seat 31 drives the guide slider 241 to slide back and forth. The conveying assembly 22 is mounted on the guide slider 241. The guide slider 241 moves back and forth as the rotating seat 31 rotates, thus ensuring that there is no relative movement between the conveying assembly 22 on the guide slider 241 and the rotating seat 31, and ensuring the effective conveying of the material 52.

[0085] Specifically, the working platform 21 is provided with a fixed conveyor seat 25, the guide slider 241 is provided with a sliding conveyor seat 26, and the rotating seat 31 is provided with sliding conveyor seats 26 on both its front and rear sides. The conveying assembly 22 is disposed on the fixed conveyor seat 25 and the sliding conveyor seat 26. The fixed conveyor seat 25 is fixed to the working platform 21 and remains stationary, while the sliding conveyor seat 26 and the guide slider 241 move back and forth as the rotating seat 31 rotates, thus ensuring that the relative position of the sliding conveyor seat 26 and the rotating seat 31 remains unchanged. In this embodiment, a set of conveying assemblies 22 includes two sliding conveyor seats 26 located on the front and rear sides of the rotating seat 31, and two fixed conveyor seats 25 located at the front and rear ends of the working platform 21, respectively.

[0086] Cooperate Figures 5 to 9 As shown, the conveying assembly 22 includes multiple rubber wheels 221 and a conveying rope 224 that is driven and engaged with each of the rubber wheels 221. The rubber wheels 221 are located on the fixed conveying seat 25 and the sliding conveying seat 26. The casters are made of rubber and have annular grooves along their circumferences that engage with the conveying rope 224. The conveying rope 224 is also made of rubber and engages with the annular grooves on the outer circumference of the rubber wheels 221. Rotation of the rubber wheels 221 drives the conveying rope 224 to move, and vice versa. Rubber wheels 221 are provided on the fixed conveying seat 25 at the front end of the work platform 21, the sliding conveying seat 26 in the middle of the work platform 21, and the fixed conveying seat 25 at the rear end of the work platform 21. The conveying rope 224 engages with the rubber wheels 221 sequentially from front to back.

[0087] In this embodiment, there are multiple sets of conveying components 22, arranged sequentially along the left and right directions of the working platform 21. Each set of conveying components 22 has the same structural dimensions, and all the conveying ropes 224 form a horizontal conveying surface for the material 52. When the material 52 is conveyed, it falls on the conveying ropes 224 (i.e., the horizontal conveying surface), and all the ropes are synchronously driven (similar to the drive of a conveyor belt) to drive the material 52 from front to back.

[0088] In this embodiment, the working platform 21 is provided with a conveyor shaft 211 extending to the left and right. The conveyor ropes 224 of the conveying components 22 all pass around the conveyor shaft 211. The conveyor shaft 211 (connected to a motor that drives its rotation) rotates, driving the conveyor ropes 224 to move. The conveyor shaft 211 is located at the front end of the working platform 21, corresponding to the position of the pressure regulating roller. All the conveyor ropes 224 in the conveying components 22 must pass around the conveyor shaft 211 at the front end of the working platform 21. This also corresponds to the entrance position of the material 52 after it is output from the pressure regulating roller and enters the working platform 21. The rotation of the conveyor shaft 211 drives the conveyor ropes 224 to move, which in turn drives the rubber wheel 221 to rotate. All the conveyor ropes 224 are driven by the same conveyor shaft 211, ensuring that the movement of all the conveyor ropes 224 is synchronized, ensuring the stability and accuracy of conveying the material 52.

[0089] In this embodiment, the rubber wheel 221 includes a conveying rubber wheel 222 and a guide rubber wheel 223 disposed on the sliding conveyor seat 26. The conveying rubber wheel 222 is located at one end of the sliding conveyor seat 26 near the rotating seat 31, and the guide rubber wheel 223 is disposed at one end of the sliding conveyor seat 26 away from the rotating seat 31. The position of the guide rubber wheel 223 is lower than the position of the conveying rubber wheel 222.

[0090] In a set of conveying components 22, there are two sliding conveying seats 26 (front sliding conveying seat 261 and rear sliding conveying seat 262) located at the front and rear sides of the rotating seat 31, and two fixed conveying seats 25 (front fixed conveying seat 251 and rear fixed conveying seat 252) located at the front and rear ends of the working platform 21, respectively. The front sliding conveying seat 261 and the rear sliding conveying seat 262 are symmetrically arranged front and rear. The end of the sliding conveying seat 26 closest to the rotating seat 31 is provided with a conveying rubber wheel 222, and the position of the conveying rubber wheel 222 is slightly lower than the position of the cutting platform 311; the end of the sliding conveying seat 26 away from the rotating seat 31 is provided with a guide rubber wheel 223, and the position of the guide rubber wheel 223 is lower than the position of the conveying rubber wheel 222. In the front sliding conveying seat 261, the conveying rubber wheel 222 is located behind the guide rubber wheel 223.

[0091] The guide roller 223 allows the conveyor rope 224 to pass under the cutting platform 311, thus ensuring the continuity and synchronization of the conveyor rope 224 at the front and rear sides of the rotating seat 31. In this embodiment, there is a gap between the bottom of the rotating seat 31 and the working platform 21 (due to the installation of structures such as the limiting slide rail 23 and the limiting slider 231), and the conveyor rope 224 passes through this gap.

[0092] Cooperate Figure 9As shown, in a set of conveying components 22, the cooperation between the conveying rope 224 and the rubber wheel 221 is as follows: (one) conveying rope 224 passes sequentially through the conveying shaft 211, the conveying rubber wheel 222 of the front sliding fixed seat, the guide rubber wheel 223 of the front sliding fixed seat, the guide rubber wheel 223 of the rear sliding fixed seat, the conveying rubber wheel 222 of the rear sliding fixed seat, the rubber wheel 221 of the rear fixed conveying seat 252, the rubber wheel 221 of the front fixed seat, and finally returns to the conveying shaft 211.
