Description

Technical Field

[0001] This invention relates to the field of material cutting technology, and in particular to a feeding device and feeding method for a cutting machine. Background Technology

[0002] Cutting machines are widely used for cutting and shearing fabrics, leather, and flexible composite materials. Before cutting, the material needs to be laid flat on the cutting machine. However, for materials that are relatively soft or thin, wrinkles or bubbles are very likely to appear. This requires interrupting the fully automated feeding and cutting process of the cutting machine, which not only consumes labor costs but also reduces the efficiency of material cutting. Summary of the Invention

[0003] The purpose of this invention is to provide a feeding device and feeding method for a cutting bed, which can automatically lay materials on the cutting bed without wrinkles or bubbles, thereby reducing labor costs while ensuring cutting accuracy and efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a feeding device for a cutting machine, including a cutting machine, a beam assembly, a roller and a main controller;

[0005] The upper surface of the cutting bed is provided with multiple sets of suction holes arranged sequentially along a first direction; each set of suction holes includes multiple suction holes arranged along a second direction; wherein the first direction is a direction parallel to the first end to the second end of the cutting bed, and the second direction is perpendicular to the first direction; each set of suction holes can be activated independently.

[0006] The crossbeam assembly is used to connect to the first end of the material to be cut, so as to pull the first end of the material to be cut to the first end of the cutting bed and fit it against the first end of the cutting bed;

[0007] The roller is located at the second end of the cutting bed, and the second end of the material to be cut is wound around the roller. The roller is used to tilt and straighten the material to be cut relative to the cutting bed when rotating in the reverse direction, and to release the material to be cut when rotating in the forward direction, so that it falls and is laid on the cutting bed.

[0008] The main controller is used to control the roller to rotate in the opposite direction to straighten the material to be cut; to control each of the air suction hole groups to start suction sequentially from the first end to the second end of the cutting bed; and to control the roller to rotate in the forward direction to gradually release the material to be cut.

[0009] In one optional embodiment of this application, the roller is positioned above the upper surface of the cutting bed, and the height difference between the roller and the cutting bed is a set height difference, so that when the material to be cut is tilted and straightened relative to the cutting bed, the included angle between the material to be cut and the cutting bed is 10° to 20°.

[0010] In one optional embodiment of this application, the reel is connected to the shaft of the drive motor, and the drive motor is used to drive the reel to rotate in the forward and reverse directions;

[0011] The main controller is used to alternately control the intake port group to start intake and control the drive motor to drive the reel to rotate forward by a set rotation angle.

[0012] In an optional embodiment of this application, the cutting bed includes adsorption strips arranged sequentially along the first direction; each adsorption strip has a set of air suction holes on its upper surface;

[0013] The adsorption strip is a hollow strip with an internal cavity; and each adsorption strip has an air intake hole on its lower surface; each air intake hole is connected to an air extraction device through an airflow pipe; each airflow pipe is equipped with an electrically controlled valve; and each electrically controlled valve is independently adjustable.

[0014] In an optional embodiment of this application, a barometer that is communicatively connected to the main controller is further provided in the cavity of each adsorption strip.

[0015] In one optional embodiment of this application, each of the air intake holes includes a combination of one or more through holes such as round holes, linear holes, and X-shaped holes.

[0016] In one optional embodiment of this application, the air intake hole is a through hole that is inclined relative to the upper surface of the adsorption strip.

[0017] A feeding method for a cutting machine, the feeding method for the cutting machine comprising:

[0018] Lay the material to be cut on the cutting table;

[0019] Keep the first end of the material to be cut in contact with the first end of the cutting bed, and pull the second end of the material to be cut straight upward so that the material to be cut is tilted relative to the upper surface of the cutting bed;

[0020] The air intake holes on the upper surface of the cutting bed are controlled to gradually start air intake from the first end to the second end, and the material to be tested is gradually released from the first end to the upper surface of the cutting bed so that the material to be cut is laid flat from the first end to the second end of the cutting bed.

[0021] In an optional embodiment of this application, controlling the air suction hole group on the upper surface of the cutting bed to gradually start suction from the first end to the second end, and controlling the material to be tested to be gradually released from the first end to the upper surface of the cutting bed, includes:

[0022] Control the current intake port group to start intake;

[0023] Control the material to be cut to release a material segment into the area where the air suction hole group is located on the cutting bed;

[0024] When the air pressure of the current air intake group reaches the set air pressure, it is determined whether the current air intake group is the last air intake group. If so, the material to be cut is laid. If not, the next adjacent air intake group is taken as the new current air intake group, and the operation of controlling the current air intake group to start air intake is executed again.

[0025] In an optional embodiment of this application, after the material to be cut is laid out segment by segment from the first end to the second end of the cutting bed, the method further includes:

[0026] The two end air intake groups located at the outermost end of the cutting bed are controlled to maintain the air intake state, and all air intake groups other than the end air intake groups are controlled to close.

[0027] The material to be cut is then cut.

[0028] The present invention provides a feeding device and method for a cutting bed equipment. The cutting bed equipment includes a cutting bed, a crossbeam assembly, a roller, and a main controller. The upper surface of the cutting bed is provided with multiple sets of suction holes arranged sequentially along a first direction. Each suction hole set includes multiple suction holes arranged along a second direction. The first direction is parallel to the direction from the first end to the second end of the cutting bed, and the second direction is perpendicular to the first direction. Each suction hole set can be activated independently. The crossbeam assembly is used to connect to the first end of the material to be cut. Next, the first end of the material to be cut is pulled to the first end of the cutting bed and made to fit against the first end of the cutting bed; the winding wheel is set at the second end of the cutting bed, and the second end of the material to be cut is wound on the winding wheel; the winding wheel is used to straighten the material to be cut relative to the cutting bed when rotating in the reverse direction, and to release the material to be cut when rotating in the forward direction, so that it falls and is laid on the cutting bed; the main controller is used to control the winding wheel to rotate in the reverse direction to straighten the material to be cut; and to control each air suction hole group to start suction sequentially from the first end to the second end of the cutting bed, and to control the winding wheel to rotate in the forward direction to gradually release the material to be cut.

[0029] In this application, a cutting bed is provided with multiple sets of suction holes arranged sequentially from the first end to the second end of the cutting bed, each capable of independent suction. Furthermore, the winding wheel for winding the material to be cut can rotate forward and reverse, thereby straightening and releasing the material. Thus, by utilizing the reverse rotation of the winding wheel in conjunction with the pressing action of the crossbeam assembly on the free end of the material to be cut, the material can be tilted and straightened above the cutting bed. Furthermore, by utilizing the cooperative action between the winding wheel and the suction hole sets on the cutting bed, the suction hole sets are controlled group by group from the first end to the second end of the cutting bed. The adsorption process is initiated group by group, and the rollers are controlled to rotate forward step by step to remove the material to be cut segment by segment. This allows the material to be adsorbed onto the surface of the cutting bed without air bubbles or wrinkles, ultimately achieving a flat and smooth surface for the material. Furthermore, the suction from the air holes on the cutting bed prevents the laid-out material from shifting again, thus avoiding wrinkles and air bubbles and effectively ensuring the stability of the flat and smooth surface. Therefore, this application achieves automated and flat material laying on the cutting bed, reducing manual labor and ensuring subsequent cutting accuracy. Attached Figure Description

Detailed Implementation

[0044] The core of this invention is to provide a feeding device and a feeding method for a cutting bed, which can automatically lay materials flat on the cutting bed without wrinkles or bubbles, providing support for the subsequent precise cutting of materials.

[0045] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the feeding device of the cutting equipment provided in the embodiments of this application; Figure 2 for Figure 1 Top view; Figure 3 Another schematic diagram of the feeding device of the cutting equipment provided in the embodiments of this application; Figure 4 for Figure 3 A top-view structural diagram. (Reference) Figure 1 and Figure 3The basic structure of the feeding device of the cutting machine in this application includes a cutting bed 1, a crossbeam assembly 2, and a roller 3; wherein, the cutting bed 1 is a horizontally arranged flat structure, mounted on a support structure 4; a roller 2 is provided at the second end of the cutting bed 1, and the material to be cut 100 not laid on the cutting bed 1 is wound around the roller 3; in addition, on the support structure 4, slide rails 5 for supporting the crossbeam assembly 2 are provided on both sides of the cutting bed 1, the crossbeam assembly 2 is located directly above the cutting bed 1 and both ends are mounted on the slide rails 5, thereby allowing the crossbeam assembly 2 to slide above the cutting bed 1, such as... Figure 1 and Figure 3 The diagrams shown are schematics of the beam assembly 2 sliding to the middle position of the cutting bed 1 and sliding to the first end of the cutting bed 1, respectively.

[0047] During the process of laying the material to be cut 100 onto the cutting table 1, the crossbeam assembly 2 first slides to a position close to the second end of the cutting table 1 and connects with the free end of the material to be cut 100 on the roller 3. The crossbeam assembly 2 drives the free end of the material to be cut 100 to slide towards the first end of the cutting table 1. At the same time, the roller 3 rotates in the forward direction to release the material to be cut 100 until the crossbeam assembly 2 moves to the first end of the cutting table 1. Obviously, at this time the material to be cut 100 can be laid on the upper surface of the cutting table 1.

[0048] Obviously, the material 100 to be cut is laid freely on the cutting table 1 without tension at both ends, which makes it easy for wrinkles or air bubbles to appear on the surface of the cutting table 1. If the material 100 is cut directly, it will obviously cause a large cutting error. Currently, it is mainly smoothed and flattened by hand, which requires dedicated manpower. Moreover, because the material is soft, even after manual smoothing, slight disturbances in the environment (such as airflow or vibration) may cause the material 100 to wrinkle again.

[0049] Based on this, combined Figures 1 to 7 , Figure 5 This is a schematic diagram of the cutting bed structure provided in an embodiment of this application; Figure 6 A schematic diagram of the material release section where the reel rotates in the forward direction, as provided in an embodiment of this application; Figure 7 This is a schematic diagram of the first structure of the adsorption strip provided in the embodiments of this application.

[0050] In one specific embodiment of this application, the feeding device of the cutting machine may include:

[0051] Cutting bed 1, crossbeam assembly 2, roller 3, and main controller;

[0052] The upper surface of the cutting bed 1 is provided with multiple sets of suction holes arranged sequentially along a first direction; each set of suction holes includes multiple suction holes 10 arranged along a second direction; the first direction is a direction parallel to the first end to the second end of the cutting bed 1, and the second direction is perpendicular to the first direction; each set of suction holes can be activated independently.

[0053] The crossbeam assembly 2 is used to connect to the first end of the material to be cut 100 so as to pull the first end of the material to be cut 100 to the first end of the cutting bed 1 and fit it against the first end of the cutting bed 1;

[0054] The roller 3 is located at the second end of the cutting bed 1, and the second end of the material to be cut 100 is wound on the roller 3. The roller 3 is used to tilt and straighten the material to be cut 100 relative to the cutting bed 1 when rotating in the reverse direction, and to release the material to be cut 100 when rotating in the forward direction, so that it falls and is laid on the cutting bed 1.

[0055] The main controller is used to control the roller 3 to rotate in the opposite direction to straighten the material to be cut 100; to control each air suction hole group to start suction sequentially from the first end to the second end of the cutting bed 1, and to control the roller 3 to rotate in the forward direction to gradually release the material to be cut 100.

[0056] like Figure 5 and Figure 7 As shown, Figure 7 The diagram shows a partial structural schematic of a set of suction hole groups on the cutting bed 1. In this application, multiple sets of suction hole groups are sequentially arranged on the cutting bed 1 from the first end to the second end (i.e., along the first direction), and the suction holes 10 in the same set are arranged sequentially along the second direction. The first and second directions are perpendicular to each other, meaning that a large number of suction holes 10 are provided and covered on the entire upper surface of the cutting bed 1. Based on this, the suction activation of each suction hole group is independent and controllable, meaning that along the first direction, which section of the cutting bed 1 begins to absorb the material 100 to be cut is independently controllable, thus providing the possibility for segment-by-segment absorption of the material 100 to be cut in the first direction. Furthermore, the crossbeam assembly 2 also includes a pressure strip 21, which can press the end of the material 100 to be cut, which is connected to the crossbeam assembly 2, onto the upper surface of the cutting bed 1. Moreover, the roller 3 in this embodiment can not only rotate forward to release the material 100 to be cut, but also rotate in the reverse direction to retract and straighten the material 100 to be cut.

[0057] Based on this, after the material to be cut 100 is initially laid on the cutting bed, the free end of the material to be cut (i.e., the end connected to the crossbeam assembly) is pressed against the first end of the cutting bed by the pressure strip 21 in the crossbeam assembly 2. Then, the material to be cut is retracted by the reversing motion of the roller 3, thus straightening the material to be cut 100. Furthermore, in order to allow the material to be cut 100 to be inclined above the cutting bed 1, the roller 3 can be positioned above the upper surface of the cutting bed 1, so that the height difference between the roller 3 and the cutting bed 1 is a predetermined height difference; and as... Figure 3 As shown, this height difference allows the angle α between the material to be cut 100 and the upper surface of the cutting bed 1 to be between 10° and 20° when the material to be cut 100 is straightened; for example, the angle between the material to be cut 100 and the upper surface of the cutting bed 1 can be 15°. In short, this angle should not exceed 30° to minimize the difficulty of adsorbing the thick material to be cut 100. Of course, in practical applications, a crossbar parallel to the roller 3 can also be set between the roller 3 and the cutting bed 1. If the roller is higher than the crossbar, the material to be cut 100 will pass under the crossbar and then extend onto the cutting bed 1; if the roller 3 is lower than the crossbar, the material to be cut 1 will pass over the crossbar and then extend onto the cutting bed 1. As long as the crossbar is higher than the upper surface of the cutting bed 1, it can also be ensured that when the material to be cut 100 is straightened, the section above the cutting bed 1 is inclined relative to the cutting bed 1.

[0058] Once the material 100 to be cut is tilted and straightened, the suction holes can be activated one by one. The main controller can first control the first group of suction holes at the first end of the cutting bed 1 to start suction. This suction group can generate a downward suction force on the material section directly above it. Then, the roller 3 is controlled to rotate forward at a certain angle, so that the section of material 100 to be cut that is suctioned adheres to the area where the suction hole group is located due to the suction force. It can be understood that the length of the material 100 to be cut released by the forward rotation angle of the roller 3 should be exactly equal to the width of the material section of the material 100 to be cut covering the group of suction holes in the first direction. This ensures that the section of the material 100 not being suctioned remains straight, thereby ensuring to a certain extent that the material 100 to be cut can be suctioned by the suction hole group without wrinkles. Meanwhile, because the suction hole group sucks away the air in the gap between the material to be cut 100 and the cutting bed 1, thus preventing air bubbles from being generated when the material to be cut 100 is adsorbed on the surface of the cutting bed 1; when the first group of suction holes has finished adsorbing the material to be cut 100, the main controller can control the adjacent second group of suction holes to start adsorption, and then control the roller 2 to rotate forward at a certain angle, so that the roller 3 releases a certain section of the material to be cut 100 again, so that the second group of suction holes also finishes adsorbing the material to be cut 100 directly above it. The main controller can then control the third group of suction holes to start suction again. By repeatedly and alternately controlling the suction hole group to start suction and controlling the roller 3 to rotate forward at the set rotation angle, the material to be cut 100 can be adsorbed segment by segment onto the upper surface of the cutting bed 1.

[0059] like Figure 6 As shown, the angle of each forward rotation of the drive motor driving the reel 3 by the main controller should meet the following requirements: ,in, The angle of positive rotation, and The width of the material segment that a single set of suction holes can adsorb in the first direction. This refers to the winding diameter of the outermost layer of material 100 currently wound on the winding wheel 3. When the thickness of the material wound on the winding wheel 3 does not change significantly, the width of the material segment released each time in the first direction is the same; that is, the arc length of the material released from the winding wheel is basically the same. Therefore, the angle of forward rotation required each time should also be basically the same. Of course, in practical applications, the angle of forward rotation required for the winding wheel 3 when each set of adsorption holes begins adsorption can be pre-calibrated.

[0060] Based on the above discussion, in order to achieve the forward and reverse rotation of the reel 3, in practical applications, the reel 3 can be connected to a drive motor, specifically connected to the shaft of the drive motor. The main controller controls the forward and reverse rotation of the drive motor, thereby causing the reel 3 to rotate in the forward and reverse directions accordingly. Furthermore, the main controller in this application can be a PLC controller.

[0061] Based on this, such as Figure 5 As shown, in another optional embodiment of this application, the cutting bed may further include:

[0062] The cutting bed 1 includes adsorption strips 11 arranged sequentially along a first direction; each adsorption strip 11 has a set of air suction holes on its upper surface.

[0063] The adsorption strip 11 is a hollow strip with an internal cavity; and each adsorption strip 11 has an air intake hole on its lower surface; each air intake hole is connected to an air extraction device through an airflow pipe 12; each airflow pipe 12 is equipped with an electric control valve 13; each electric control valve 13 is independently adjustable.

[0064] like Figure 5 As shown, the cutting bed 1 in this embodiment can be formed by splicing together several hollow strips. The interior of each hollow strip is equivalent to an airflow channel. Each air intake 10 of the same group of air intake holes is set on the upper surface of the hollow strip. An air intake through hole is opened on the lower surface of the hollow strip, which is connected to the air extraction device through the airflow pipe 12. Each airflow pipe 12 is equipped with an electric control valve 13. Thus, when each group of air intake holes starts to extract air, the air extraction device is first controlled to start to extract air. Then, the electric control valves 13 on each airflow channel are sequentially controlled to be adjusted from the closed state to the open state. When the corresponding electric control valve is opened, the group of air intake holes can start to extract air. Conversely, when the corresponding electric control valve 13 is closed, the group of air intake holes can stop to extract air.

[0065] also, Figure 5 To facilitate understanding of the air intake structure of the cutting bed 1, the airflow duct 12 and the electrically controlled valve 13 are shown in perspective; however, it is understandable that in practical applications, from Figure 5 From the perspective shown, the airflow duct 12 and the solenoid valve 13 should be located below each adsorption strip 11 and not visible.

[0066] In addition, to facilitate the main controller in further determining whether the suction hole group currently initiating suction has completely adsorbed the material segment above it, a barometer can be installed in each suction strip 11. When the material segment completely adheres to and covers the surface of the suction strip 11, the suction holes on the suction strip 11 are covered and sealed by the material segment, and the internal air pressure will quickly stabilize. The air pressure should be equivalent to the negative pressure of the suction device. This can be used as a basis for judging whether the material segment corresponding to each suction strip 11 has been successfully adsorbed. If the suction time of the suction strip 11 exceeds a certain time threshold, and the negative pressure measured by the barometer does not reach the negative pressure of the suction device, it is very likely that the adsorption process of the material to be cut 100 has malfunctioned. At this time, the main controller can activate an alarm to remind the staff to check in time.

[0067] Of course, the cutting bed 1 in this application is not necessarily formed by splicing together various adsorption strips 11. It can also be a complete plate-like structure with multiple independent airflow pipes 12. Each airflow pipe 12 is independently connected to the air extraction device, which can also achieve the technical solution of this application.

[0068] Further optional, such as Figures 7 to 9 As shown, the air suction holes provided on the cutting bed 1 of this application can be a combination of one or more through holes, such as round holes, linear holes, X-shaped holes, etc. Figure 7 Taking the suction hole 10 as an example, multiple circular holes can be evenly arranged in an array across the entire adsorption strip to ensure the adsorption effect of the adsorption strip on the material in the designated area. Figure 8 As shown, taking the suction hole 10 as an example, multiple parallel linear holes can be arranged sequentially along the second direction on the adsorption strip 11. And as... Figure 9 As shown, taking the suction hole 10 as an example, multiple X-shaped holes can be sequentially set on the adsorption strip 11.

[0069] Furthermore, to prevent the suction holes 10 on the suction strip 11 from causing depressions on the upper surface of the suction strip 11, thus affecting the flatness of the upper surface of the cutting bed, and to prevent the flexible material to be cut 100 from being recessed into the suction holes 10 due to the suction effect of the suction holes 10, thereby interfering with the subsequent cutting process, such as... Figure 10 As shown, each suction hole 10 can be further configured as a through hole extending obliquely relative to the upper surface of the adsorption strip 11; that is, the depth of the recessed structure formed by each suction hole 10 on the upper surface of the cutting bed 1 is reduced, so as to ensure the flatness of the material to be cut 100 on the upper surface of the cutting bed 1 as much as possible, thereby ensuring the subsequent cutting accuracy.

[0070] In addition, it should be noted that the size of the suction hole 10 in this application can be determined based on the softness of the material to be cut 100. The softer the material to be cut 100 is, the smaller the suction hole 10 should be. Conversely, if the material to be cut 100 is less soft, the size of the suction hole 10 can be appropriately increased. The area covered by each group of suction holes on the cutting bed 1 can also be appropriately increased.

[0071] Based on the above discussion, this application provides a cutting bed with multiple sets of suction holes arranged sequentially from the first end to the second end of the cutting bed. The winding wheel used to wind the material to be cut can rotate forward and backward, thereby straightening and releasing the material. Thus, during the actual process of laying the material to be cut onto the upper surface of the cutting bed, the interaction between the winding wheel and the suction holes on the cutting bed allows the material to be released segment by segment onto the cutting bed from the first end to the second end, ensuring that the material is laid segment by segment on the cutting bed. During the process, the suction effect of the air inlet effectively prevents the formation of air bubbles, and the unlaid sections are always kept straight, thus avoiding wrinkles. This achieves a wrinkle-free and bubble-free flat laying of the material to be cut on the upper surface of the cutting bed. Furthermore, when the material to be cut is completely laid on the cutting bed, the adsorption force of the cutting bed also prevents it from moving and causing wrinkles to reappear, effectively ensuring the stability of the flat laying of the material to be cut. The entire process requires no manual intervention, reducing manual labor while ensuring the overall cutting accuracy.

[0072] Based on any of the above embodiments, this application also provides an embodiment of a feeding method for a cutting bed equipment. It is understood that the feeding method for the cutting bed equipment in this embodiment can be applied to the feeding device of the cutting bed equipment described in any of the above embodiments.

[0073] like Figure 11 As shown, in an optional embodiment of this application, the feeding method of the cutting machine may include:

[0074] S1: Lay the material to be cut on the cutting bed;

[0075] S2: Keep the first end of the material to be cut in contact with the first end of the cutting bed, and pull the second end of the material to be cut straight up so that the material to be cut is tilted relative to the upper surface of the cutting bed;

[0076] S3: Control each air intake group on the upper surface of the cutting bed to gradually start air intake from the first end to the second end, and control the material to be tested to be gradually released from the first end to the upper surface of the cutting bed so that the material to be cut is laid flat from the first end to the second end of the cutting bed.

[0077] As described above, the free end of the material to be cut is pulled from the second end to the first end of the cutting bed by the crossbeam assembly in the cutting bed equipment. Simultaneously, the rollers are controlled to rotate forward to release the material, thus initially laying it on the cutting bed. Then, the pressure strips in the crossbeam assembly press the free end of the material against the first end of the cutting bed, and the rollers are rotated in the opposite direction, thus tilting and straightening the material above the cutting bed, with the free end adhering to the first end. At this point, by controlling the sequential activation of the suction holes on the cutting bed and simultaneously controlling the rollers to rotate in the opposite direction at set angles, the material is gradually adsorbed onto the surface of the cutting bed. The specific process of adsorbing the material can include:

[0078] S31: Controls the current intake port group to start intake;

[0079] S32: Controls the release of material from the material to be cut onto the area where the suction holes are located on the cutting bed;

[0080] S33: If the air pressure of the current air intake group reaches the set air pressure, determine whether the current air intake group is the last air intake group. If yes, the material to be cut is laid. If no, the next adjacent air intake group is taken as the new current air intake group, and proceed to S31.

[0081] like Figure 12 As shown, the main controller can be a PLC controller, which can alternately control the suction hole group to start suction and control the roller to rotate forward to set the rotation angle, so as to gradually achieve the adsorption and spreading of the material in the section.

[0082] Further, optionally, when the portion of the material to be cut completely covers the cutting bed, it may further include:

[0083] S41: Control the two end air intake groups located at the outermost end of the cutting bed to maintain the air intake state, and control all air intake groups except the end air intake groups to close.

[0084] S42: Cut the material to be cut.

[0085] During the cutting process, the two sets of end suction holes located at the outermost end of the cutting bed maintain a suction state, which can, to some extent, prevent the material to be cut from moving during the cutting process, thereby ensuring cutting accuracy. At the same time, closing the suction hole group in the middle area can reduce adsorption energy consumption to some extent. Of course, considering the problem that the end material and the middle area material are separated during the cutting process, resulting in no fixed force on the middle area material, some suction hole groups can be kept in a suction state at intervals while others are stopped, or all can be kept in a suction state, all of which can achieve the technical solution of this application.
