Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and in particular to a punching device for a vacuum forming line. Background Technology

[0002] Vacuum-formed products are widely used in packaging, electronics, medical devices, and other fields. The production of vacuum-formed products typically involves two main processes: vacuum forming and die-cutting. In traditional production methods, these two processes are often performed separately: the sheet material is first formed on a vacuum forming machine, and then the formed sheet is transported to a die-cutting machine for separation. This process results in low production efficiency and can easily cause deformation or contamination of the sheet material during handling.

[0003] To improve production efficiency, some inline punching and cutting equipment has emerged, integrating the thermoforming and punching processes into a single production line. However, existing inline punching and cutting equipment still has shortcomings in terms of sheet material feeding, positioning accuracy, punching quality, and automation. For example, the sheet material is prone to shifting during feeding, affecting punching accuracy; the separation of finished products and waste after punching is not thorough enough, requiring manual assistance; and the equipment is complex to adjust, making it difficult to adapt to the production needs of products with different specifications.

[0004] Therefore, developing a compact, highly automated, precisely positioned, and easily adjustable thermoforming die-cutting line has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention aims to improve at least one technical problem in the prior art.

[0006] This invention provides a punching device for a vacuum forming line, comprising:

[0007] frame;

[0008] A film pulling machine, wherein the film pulling machine is mounted on the frame;

[0009] A cutting machine, located downstream of a sheet-pulling machine, is used to punch the sheet material fed in by the sheet-pulling machine.

[0010] A winding mechanism is used to wind up the cut sheet material.

[0011] The discharge mechanism is located between the winding mechanism and the cutting machine, and is used to output the punched parts.

[0012] The sheet pulling machine includes a feeding guide mechanism, which includes an upper guide plate, a lower guide plate, and a guide plate connecting assembly. The guide plate connecting assembly makes the distance between the upper guide plate and the lower guide plate adjustable.

[0013] The upper guide plate is fixed on the frame. The guide plate connecting assembly includes a height adjustment support block, a height adjustment screw, and a connecting post. The height adjustment support block is fixed on the frame and has a height adjustment screw hole that extends vertically through the support block. The middle part of the height adjustment screw is threadedly connected to the screw hole. The lower end of the screw has a T-shaped longitudinal section. The upper side of the connecting post has a T-shaped connecting hole. The lower end of the screw is rotatably accommodated in the connecting hole. The lower guide plate is mounted on the connecting post.

[0014] The beneficial effects of this invention: The vacuum forming line punching equipment of this invention, by configuring a sheet pulling machine, a cutting machine, a winding mechanism, and a discharge mechanism, conveniently realizes the separation of waste material and parts after vacuum forming. ， The upper and lower guide plates of the feeding guide mechanism effectively limit the entry position of the material belt. Each guide plate is connected to the frame via a guide plate connecting assembly, allowing for adjustment of the height difference between them to accommodate material belts of varying thicknesses. The guide plate connecting assembly comprises a height adjustment support block, a height adjustment screw, and a connecting column. Rotating the height adjustment screw easily moves the connecting column up and down, thus changing the position of the upper or lower guide plate, facilitating convenient adjustment.

[0015] As a sub-solution of the above technical solution, the strip pulling machine further includes a fixed clamping plate mechanism. This mechanism includes a fixed clamping plate driver, a lower fixed clamping plate, and an upper fixed clamping plate. The fixed clamping plate driver is mounted on the frame, the lower fixed clamping plate is fixed to the frame, and the upper fixed clamping plate is driven by the fixed clamping plate driver. The fixed clamping plate driver drives the upper and lower fixed clamping plates to move closer together. The fixed clamping plate mechanism reinforces the strip during punching. When the fixed clamping plate mechanism drives the upper fixed clamping plate towards the lower fixed clamping plate via the fixed clamping plate driver, the upper and lower fixed clamping plates jointly clamp the strip, effectively reducing the strip's deviation during punching, effectively improving the cutting accuracy of the cutting machine, and ultimately improving the precision of the finished product.

[0016] As a sub-solution of the above technical solution, the strip pulling machine includes a movable clamping plate mechanism. The movable clamping plate mechanism includes an upper movable clamping plate, a lower movable clamping plate, a movable clamping plate driver, a movable base plate, and a feeding mechanism. The feeding mechanism is mounted on the frame and drives the movable base plate to move. The movable clamping plate driver is mounted on the movable base plate and is connected to the upper movable clamping plate driver, causing the upper movable clamping plate to move towards the lower movable clamping plate. The lower movable clamping plate is fixed to the movable base plate. By setting the movable clamping plate mechanism to move the strip a certain distance and feed it into the cutting machine, it is beneficial to improve the positioning accuracy between the strip and the cutting machine, and also to improve the positioning accuracy between the strip and the punching machine, ultimately improving the accuracy of the finished parts after the strip is punched.

[0017] As a sub-solution of the above technical solution, the feeding mechanism includes a feeding drive motor, a conveyor belt, a feeding guide rail, and a clamping block. Both the feeding drive motor and the conveyor belt are mounted on the frame. The feeding drive motor drives the conveyor belt to rotate cyclically. The clamping block holds the conveyor belt and moves with it. The clamping block is fixedly connected to the movable base plate. The movable base plate is provided with a feeding slider, which is slidably connected to the feeding guide rail. The feeding mechanism operates by using a feeding drive motor to drive the conveyor belt, allowing for convenient feeding of the material strip into the punching machine. Furthermore, by controlling the feeding amount of the feeding drive motor, the feeding distance can be easily adjusted according to different material strips and punching machine dies. In addition, the feeding mechanism is also equipped with a feeding guide rail and a clamping block. The feeding guide rail provides stable support to the movable base plate, ensuring the stability of the material strip fed by the upper and lower movable clamping plates, further improving the accuracy of the material strip feeding.

[0018] As a sub-solution of the above technical solution, the sheet pulling machine further includes a horizontal adjustment mechanism. The horizontal adjustment mechanism includes a horizontal adjustment drive screw, a horizontal adjustment support plate, a horizontal adjustment sleeve, and a horizontal adjustment guide post. The horizontal adjustment guide post is fixed to the frame, and the horizontal adjustment support plate is slidably connected to the horizontal adjustment guide post. The fixed clamping plate driver, the lower fixed clamping plate, the feed drive motor, and the feed guide rail are all mounted on the horizontal adjustment support plate. The horizontal adjustment sleeve is fixedly connected to the horizontal adjustment support plate, and the horizontal adjustment drive screw is rotatably mounted on the frame and rotatably connected to the horizontal adjustment sleeve. By configuring the horizontal adjustment mechanism, the movable clamping plate mechanism and the fixed clamping plate mechanism can be adjusted to the same lateral position, thereby adapting to clamping strips of different widths.

[0019] As some sub-solutions of the above technical solution, both the upper fixed clamping plate and the lower fixed clamping plate are provided with a first guide angle on the side away from the punching machine, or both the upper movable clamping plate and the lower movable clamping plate are provided with a second guide angle on the side away from the punching machine. By configuring the guide angle, the material strip can enter more easily through the guide angle, improving the stability of the material strip conveying.

[0020] As a sub-solution of the above technical solution, the thermoforming inline punching equipment further includes a displacement sensor, which is located on the side of the sheet pulling machine away from the punching machine. By configuring the displacement sensor, the accuracy of the feeding mechanism in moving the material strip through the movable base plate, upper movable clamping plate, and lower movable clamping plate can be improved.

[0021] As a sub-solution of the above technical solution, the winding mechanism includes a winding motor and a winding component. The winding motor is mounted on the frame, and the winding component includes a base plate and support shafts. The support shafts are arranged in a circumferential array on the base plate, and the winding motor is drivenly connected to the base plate. By setting a winding mechanism composed of a support shaft array, the winding of the material strip can be conveniently and reliably achieved.

[0022] As a sub-solution of the above technical solution, the discharge mechanism includes a discharge longitudinal movement driver, a discharge lifting driver, and a suction cup assembly. The discharge longitudinal movement driver is mounted on the frame and is drivenly connected to the discharge lifting driver. The discharge lifting driver is also drivenly connected to the suction cup assembly. By setting up the discharge mechanism, the finished parts punched by the punching machine can be conveniently sent out. Attached Figure Description

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following is combined Figures 1 to 4 Embodiments of the present invention will be described.

[0036] The vacuum forming line punching equipment of this invention is mainly used for automated punching of vacuum-formed sheets, achieving efficient separation of finished products and waste. The core components of the equipment include a frame, a sheet pulling machine 1, a cutting machine 2, a winding mechanism 3, and a discharge mechanism 4. The sheet pulling machine 1 accurately transports the vacuum-formed sheets to the cutting station; the cutting machine 2 punches the sheets, separating the target parts; the winding mechanism 3 winds up the remaining waste sheets after punching; and the discharge mechanism 4 removes the finished parts from the equipment. The entire equipment achieves continuous production by coordinating the actions of each mechanism, which helps improve production efficiency and reduce manual intervention.

[0037] This embodiment of a vacuum forming line punching device includes:

[0038] frame;

[0039] A film pulling machine 1 is mounted on the frame;

[0040] Cutting machine 2, which is located downstream of sheet pulling machine 1, is used to punch the sheet fed in by sheet pulling machine 1.

[0041] The winding mechanism 3 is used to wind up the cut sheet material;

[0042] The discharge mechanism 4 is located between the winding mechanism 3 and the cutting machine 2, and is used to output the punched parts.

[0043] Specifically, a sheet-pulling machine 1, a cutting machine 2, a discharge mechanism 4, and a winding mechanism 3 are sequentially arranged on the frame along the sheet conveying direction. The cutting machine 2 is located downstream of the sheet-pulling machine 1 and receives the sheet fed by the sheet-pulling machine 1 for punching. The discharge mechanism 4 is located between the winding mechanism 3 and the cutting machine 2 and is used to remove the punched parts from the sheet and convey them to a designated position. The winding mechanism 3 is used to wind up the waste strip after punching (i.e., the cut sheet). To better coordinate the detection of the sheet conveying position with the control of the sheet-pulling machine 1's feeding rhythm, this invention also includes a displacement sensor 5. This displacement sensor 5 is installed on the side of the sheet-pulling machine 1 away from the cutting machine 2 and can detect the displacement information of the sheet entering the sheet-pulling machine 1 in real time. This displacement information allows for adjustment of the feeding amount of the sheet-pulling machine 1, helping to improve the accuracy of sheet feeding and reduce inaccurate punching positions caused by feeding amount deviations. In this embodiment, the displacement sensor 5 is a laser sensor.

[0044] The vacuum forming line punching equipment of the present invention, by configuring a sheet pulling machine 1, a cutting machine 2, a winding mechanism 3 and a discharge mechanism 4, conveniently realizes the separation of waste materials and parts after vacuum forming.

[0045] The sheet feeding machine 1, as the core actuator for sheet conveying, includes a feeding guide mechanism, a fixed clamping plate mechanism 11, a movable clamping plate mechanism 13, a feeding mechanism, and a horizontal adjustment mechanism. These mechanisms work together to achieve stable sheet feeding. The feeding guide mechanism includes an upper guide plate, a lower guide plate, and a guide plate connecting assembly 12. The upper and lower guide plates are arranged vertically opposite each other. The upper guide plate is fixedly connected to the frame, while the lower guide plate is connected to the frame via the guide plate connecting assembly 12. The guide plate connecting assembly 12 allows for adjustment of the distance between the upper and lower guide plates to accommodate sheets of different thicknesses. Specifically, the guide plate connecting assembly 12 includes a height adjustment support block 121, a height adjustment screw 122, and a connecting post 123. The height adjustment support block 121 is fixed to the frame by bolts or other fasteners. A vertically penetrating height adjustment screw hole is provided on the height adjustment support block 121. The external thread of the height adjustment screw 122 is compatible with the internal thread of the height adjustment screw hole, allowing the height adjustment screw 122 to be screwed into the height adjustment screw hole. A T-shaped connecting hole is provided on the upper side of the connecting post 123. The lower end of the height adjustment screw 122 has a T-shaped longitudinal section. The part is rotatably housed in the connecting hole. The longitudinal section of both the connecting hole and the height adjustment screw 122 is T-shaped and their shapes match each other. When the lower end of the height adjustment screw 122 is rotatably housed in the connecting hole, the height of the lower end of the height adjustment screw 122 can be changed by rotating through the internal thread of its external thread height adjustment support block. The rotational freedom of the lower end of the height adjustment screw 122 and the connecting hole can prevent the connecting column 123 from rotating. At the same time, the T-shaped structure of the lower end of the height adjustment screw 122 and the connecting hole can drive the connecting column 123 to move up and down.

[0046] The upper guide plate is fixedly connected to the connecting column 123 by bolts or other connecting parts. When it is necessary to adjust the distance between the upper and lower guide plates, the height adjustment screw 122 is rotated. Since the height adjustment screw 122 is threadedly engaged with the height adjustment support block 121, and the lower end of the height adjustment screw 122 is rotatably connected to the connecting hole of the connecting column 123, the rotation of the height adjustment screw 122 can drive the connecting column 123 to move vertically while avoiding driving the connecting column 123 to rotate, thereby driving the upper or lower guide plate to move, realizing the adjustment of the distance between them. Through the structural design of the above-mentioned guide plate connecting assembly 12, the present invention can flexibly adapt to the guiding requirements of various specifications of material plates, reducing the offset or jamming of the material plates during the guiding process.

[0047] The fixed clamping mechanism 11 includes a fixed clamping driver 113, a lower fixed clamping plate 112, and an upper fixed clamping plate 111. The fixed clamping driver 113 is mounted on the frame via a bracket. The lower fixed clamping plate 112 is fixed to the frame via bolts or other fasteners. The upper fixed clamping plate 111 is connected to the output end of the fixed clamping driver 113 and can move vertically under the drive of the fixed clamping driver 113. When the fixed clamping driver 113 is activated, it drives the upper fixed clamping plate 111 to move closer to the lower fixed clamping plate 112 until the upper fixed clamping plate 111 and the lower fixed clamping plate 112 jointly clamp the material sheet, thus fixing the material sheet at that position. When it is necessary to release the material sheet, the fixed clamping driver 113 drives the upper fixed clamping plate 111 to move away from the lower fixed clamping plate 112. The fixed clamping mechanism 11 can position the material sheet when the movable clamping mechanism 13 moves the material sheet, reducing the movement of the material sheet during the conveying process and helping to improve the stability of the material sheet conveying.

[0048] The movable clamping mechanism 13 includes an upper movable clamping plate 131, a lower movable clamping plate 132, a movable clamping plate driver 133, a movable base plate 134, and a feeding mechanism. The feeding mechanism is mounted on the frame and is used to drive the movable base plate 134 to move along the sheet conveying direction. The movable clamping plate driver 133 is mounted on the movable base plate 134, and its output end is connected to the upper movable clamping plate 131. The lower movable clamping plate 132 is fixed to the movable base plate 134 by fasteners such as bolts. The upper movable clamping plate 131 can move vertically under the drive of the movable clamping plate driver 133 to achieve clamping or separation from the lower movable clamping plate 132. When the movable clamping mechanism 13 needs to feed the sheet, the movable clamping driver 133 drives the upper movable clamping plate 131 to move down and clamp the sheet with the lower movable clamping plate 132. Then, the feeding mechanism drives the movable base plate 134 to move along the sheet feeding direction, driving the sheet to be fed towards the cutting machine 2. When the movable base plate 134 moves to the designated position, the movable clamping driver 133 drives the upper movable clamping plate 131 to move up and release the sheet. The feeding mechanism drives the movable base plate 134 to reset, waiting for the next feeding action. By alternating clamping and moving of the fixed clamping mechanism 11 and the movable clamping mechanism 13, continuous feeding of the sheet can be achieved, improving the continuity of sheet feeding.

[0049] The feeding mechanism includes a feeding drive motor 135, a conveyor belt 136, a feeding guide rail, and a clamping block. The feeding drive motor 135 is mounted on the frame via a motor mount. The conveyor belt 136 is mounted on the frame via a conveyor belt 136 pulley. The output shaft of the feeding drive motor 135 is connected to the conveyor belt 136 pulley via a coupling or belt drive, which can drive the conveyor belt 136 to rotate cyclically. The clamping block is fixed to the conveyor belt 136 by bolts and moves synchronously with the conveyor belt 136. At the same time, the clamping block is connected to the movable base plate 134 by bolts, which can drive the movable base plate 134 to move with the conveyor belt 136. A feeding slider is mounted on the bottom of the movable base plate 134 by bolts. The feeding guide rail is fixed to the frame by bolts, and the feeding slider slides in cooperation with the feeding guide rail. To make the movement of the movable substrate 134 smoother and reduce shaking during the movement, the present invention provides guidance for the movement of the movable substrate 134 by sliding the feeding slider and the feeding guide rail, which helps to improve the accuracy of the movement of the movable substrate 134 and thus improve the accuracy of the sheet feeding.

[0050] Furthermore, in one embodiment of the present invention, the sheet pulling machine 1 further includes a horizontal adjustment mechanism, which includes a horizontal adjustment drive screw 141, a horizontal adjustment support plate 142, a horizontal adjustment sleeve 143, and a horizontal adjustment guide post 144. The horizontal adjustment guide post 144 is fixed on the frame, and a horizontal adjustment sliding sleeve is installed at the bottom of the horizontal adjustment support plate 142. The horizontal adjustment sliding sleeve slides in cooperation with the horizontal adjustment guide post 144, so that the horizontal adjustment support plate 142 can move laterally along the horizontal adjustment guide post 144; the fixed clamping plate driver 113 and the lower fixed... The fixed clamping plate 112, the feed drive motor 135, and the feed guide rail are all bolted to the horizontal adjustment support plate 142 and move laterally synchronously with the horizontal adjustment support plate 142. The horizontal adjustment screw sleeve 143 is fixed to the side of the horizontal adjustment support plate 142 by bolts. The horizontal adjustment drive screw 141 is rotatably mounted on the frame through a bearing seat. The external thread of the horizontal adjustment drive screw 141 is compatible with the internal thread of the horizontal adjustment screw sleeve 143. One end of the horizontal adjustment drive screw 141 can be connected to a handwheel or a drive motor. When it is necessary to adjust the lateral position of the sheet pulling machine 1, the horizontal adjustment drive screw 141 is rotated. The thread engagement between the horizontal adjustment drive screw 141 and the horizontal adjustment screw sleeve 143 drives the horizontal adjustment screw sleeve 143 to move laterally, which in turn drives the horizontal adjustment support plate 142 to move laterally along the horizontal adjustment guide post 144, thereby realizing the adjustment of the overall lateral position of the sheet pulling machine 1. This structure can adapt to the feeding requirements of sheets of different widths or adjust the lateral alignment of the sheets, which helps to improve the positional accuracy of parts during punching.

[0051] To facilitate the entry of the sheet material between the clamping plates and reduce jamming during entry, a first guide angle is provided on the side of the upper fixed clamping plate 111 and the lower fixed clamping plate 112 away from the cutting machine 2. The first guide angle gradually narrows along the direction of sheet material entry, allowing the sheet material to smoothly enter between the upper fixed clamping plate 111 and the lower fixed clamping plate 112. Alternatively, a second guide angle is provided on the side of the upper movable clamping plate 131 and the lower movable clamping plate 132 away from the cutting machine 2. The structure of the second guide angle is similar to that of the first guide angle, which can also guide the sheet material smoothly into the space between the upper movable clamping plate 131 and the lower movable clamping plate 132. By setting the guide angle, the smoothness of sheet material entry can be improved, interruptions in the sheet material conveying process can be reduced, and processing efficiency can be improved.

[0052] The cutting machine 2 includes a blanking die, a blanking driver, and a mounting frame. The mounting frame is fixed to the machine frame. The blanking die includes an upper die and a lower die. The lower die is fixed to the bottom of the mounting frame, and the upper die is connected to the output end of the blanking driver. The blanking driver is mounted on the top of the mounting frame and can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. When the sheet pulling machine 1 feeds the sheet into the blanking die of the cutting machine 2, the blanking driver drives the upper die to move downward, cooperating with the lower die to blank the sheet into parts of a preset shape. The blanking die of the cutting machine 2 can be replaced according to the shape requirements of different parts, improving the versatility of the equipment. At the same time, the blanking action of the cutting machine 2 can be linked with the feeding rhythm of the sheet pulling machine 1 through the control system to achieve continuous blanking of the sheet, which helps to improve the continuity and efficiency of processing.

[0053] The winding mechanism 3 includes a winding motor and a winding component. The winding motor is mounted on the frame via a motor mount. The winding component includes a base plate 31 and a support shaft 32. The base plate 31 is connected to the output shaft of the winding motor via a coupling and can rotate around its own axis under the drive of the winding motor. The support shafts 32 are arranged in an array along the circumference of the base plate 31 on its end face. The support shafts 32 are perpendicularly connected to the base plate 31, forming a winding space for winding the waste strip. After the punched waste strip is output from the cutting machine 2, it is wound onto the support shafts 32. The winding motor drives the base plate 31 to rotate, which in turn drives the support shafts 32 to rotate synchronously, thereby winding the waste strip. The circumferential array of the support shafts 32 allows for more even stress distribution on the waste strip during winding, reducing wrinkles. After winding, the winding component with the waste strip can be removed from the winding motor, facilitating waste recycling and improving the convenience of waste disposal.

[0054] The discharge mechanism 4 includes a discharge longitudinal drive 42, a discharge lifting drive 41, and a suction cup assembly 43. The discharge longitudinal drive 42 is fixed on the frame by a mounting base. The output end of the discharge longitudinal drive 42 is connected to the discharge lifting drive 41, which can drive the discharge lifting drive 41 to move laterally. The output end of the discharge lifting drive 41 is connected to the suction cup assembly 43, which can drive the suction cup assembly 43 to move vertically. The suction cup assembly 43 includes a suction cup mounting plate and multiple suction cups. The suction cups are evenly distributed on the bottom of the suction cup mounting plate, and the suction cups are connected to a negative pressure device through air pipes. After the cutting machine 2 completes one punching cycle, the discharge longitudinal drive 42 drives the discharge lifting drive 41 and the suction cup assembly 43 to move above the punched part. The discharge lifting drive 41 drives the suction cup assembly 43 to move downward, so that the suction cup contacts the part. The negative pressure device works to create negative pressure on the suction cup to adsorb the part. Then, the discharge lifting drive 41 drives the suction cup assembly 43 to move upward, and the discharge longitudinal drive 42 drives the suction cup assembly 43 to move above the part collection position. The negative pressure device stops working, the suction cup releases the part, and the part is discharged. To make the suction cup assembly 43 adsorb the part more stably and reduce the part falling during the conveying process, this invention sets multiple evenly distributed suction cups, which can increase the contact area between the suction cup assembly 43 and the part and improve the adsorption stability. At the same time, the cooperation between the discharge longitudinal drive 42 and the discharge lifting drive 41 can realize the precise conveying of the part and help improve the orderliness of the part collection.

[0055] In actual operation, the sheet material enters from the side of the sheet pulling machine 1 away from the cutting machine 2. It first passes through the displacement sensor 5, which detects the initial position of the sheet material and transmits the signal to the control system. The sheet material continues to be conveyed, guided by the upper and lower guide plates of the feeding guide mechanism, and enters between the fixed clamping plate mechanism 11 and the movable clamping plate mechanism 13. The control system controls the fixed clamping plate driver 113 to drive the upper fixed clamping plate 111 downwards, clamping the sheet material together with the lower fixed clamping plate 112. Simultaneously, the movable clamping plate driver 133 drives the upper movable clamping plate 131 upwards, separating it from the lower movable clamping plate 132. The feeding drive motor 135 of the feeding mechanism drives the conveyor belt 136 to rotate. The conveyor belt 136, through the clamping blocks, drives the movable base plate 134 to reset along the feeding guide rail. After the movable base plate 134 resets, the movable clamping plate driver 133 drives the upper movable clamping plate 131 downwards, clamping the sheet material together with the lower movable clamping plate 132. The fixed clamping plate driver 113... The upper fixed clamping plate 111 is moved upward to release the sheet material; the feed drive motor 135 drives the conveyor belt 136 to run again, and the movable base plate 134 is moved along the feed guide rail towards the cutting machine 2 through the clamping block, thereby driving the sheet material to be conveyed to the cutting machine 2. The displacement sensor 5 detects the displacement of the sheet material in real time to ensure that the sheet material is fed into the preset punching position; after the sheet material reaches between the punching dies of the cutting machine 2, the feeding mechanism stops working, and the punching driver of the cutting machine 2 drives the upper die to move downward, and cooperates with the lower die to punch the sheet material; after punching, the discharge mechanism 4 is activated, and the suction cup assembly 43 adsorbs the punched parts and conveys them to the collection position; the punched waste strip continues to be conveyed to the winding mechanism 3, and the winding motor drives the winding part to rotate to wind up the waste strip; then the equipment repeats the above actions to realize the continuous feeding, punching, part discharge and waste winding of the sheet material. The whole processing process has a high degree of automation, and the cooperation of each mechanism helps to improve processing efficiency and processing accuracy.
