Description

Technical Field

[0001] This invention relates to the field of cutting bed equipment technology, and in particular to a vacuum adsorption structure for a cutting bed and the cutting bed itself. Background Technology

[0002] A cutting table is a device used for cutting materials such as leather, imitation leather, fabric, and cardboard. The quality of the cutting directly affects the quality of the finished product and its wearing effect. The cutting process involves laying one or more layers of material flat on the cutting table, then drawing lines on the surface of the top layer, and finally cutting along the drawn lines. The cutting table usually has air extraction holes for vacuum extraction, which firmly adheres the material to the worktable, preventing material shifting during cutting and thus affecting the accuracy of the cutting dimensions and the garment's pattern.

[0003] Currently, there are many types of vacuum adsorption modules for cutting beds on the market, but their structures are basically very similar with no significant changes, exhibiting a high degree of similarity. Furthermore, the commonly used forward and reverse air duct structures are evenly distributed under the cutting bed, with a distribution area larger than the cutting area, leading to problems such as severe air leakage and low vacuum adsorption negative pressure. They also suffer from high noise levels and insufficient airflow. Additionally, when blowing air onto the cutting bed in the reverse direction, the inflexible adjustment of the reverse airflow force can cause air to be blown onto the cut material. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a vacuum adsorption structure for a cutting bed and a cutting bed, so as to solve the problems in the prior art where the forward and reverse blowing structure of the cutting bed has serious air leakage, resulting in low vacuum adsorption negative pressure, high noise, and inflexible adjustment of the reverse air duct blowing force, which causes the cutting material to be blown by air.

The inlet pipe sealing assemblies are used to control the opening and closing of the inlet pipes. The inlet pipe sealing assemblies include an inlet pipe sealing cylinder and an inlet pipe plug. The inlet pipe sealing cylinder is disposed on the airbag shell, and the inlet pipe plug is disposed on the piston shaft of the inlet pipe sealing cylinder. The inlet pipe plug is located in the airbag cavity and can block the inlet pipe under the movement of the piston shaft of the inlet pipe sealing cylinder. The number of inlet pipes and inlet pipe sealing assemblies are the same and correspond one-to-one.

[0007] Preferably, the branch pipe includes several bends, one end of which is connected to several air inlet pipes, and the other end is located in an independent area below the honeycomb panel.

[0009] Preferably, the micro-blowing component silencer box includes a housing, a vacuum pump suction pipe, a vacuum pump outlet pipe, a silencer pipe, a return air pipe, and a return air pipe sealing component. The vacuum pump suction pipe and the vacuum pump outlet pipe are both disposed in the housing. One end of the vacuum pump suction pipe is connected to the main pipe, and the other end is connected to the vacuum pump. One end of the vacuum pump outlet pipe is connected to the vacuum pump, and the other end is connected to the return air pipe. The end of the return air pipe away from the vacuum pump outlet pipe is connected to the vacuum pump suction pipe. One end of the silencer pipe is connected to the vacuum pump outlet pipe, and the other end is open to the atmosphere.

[0010] Preferably, the silencer pipe includes a U-shaped pipe body and a silencer outlet. The U-shaped pipe body is disposed in the housing. One end of the U-shaped pipe body is connected to the vacuum pump outlet pipe, and the other end of the U-shaped pipe body is connected to the atmosphere through the silencer outlet.

[0014] As described above, the vacuum adsorption structure and cutting bed of the present invention have the following beneficial effects:

[0015] 1. The present invention relates to a vacuum adsorption structure for a cutting bed and the cutting bed itself, comprising a main pipe, several zoned air chambers, and several branch pipes. The main pipe is connected to the branch pipes via the zoned air chambers. The end of each branch pipe is located in an independent area below the honeycomb panel. Therefore, each zoned air chamber controls the adsorption pressure intensity in one or more independent areas. Each zoned air chamber has several air inlet pipes, and the branch pipes are connected to the air inlet pipes. An air inlet pipe sealing assembly is provided on the zoned air chamber to control the opening and closing of the air inlet pipes. Therefore, when the size of the material to be cut decreases, the air inlet pipes can be closed by the air inlet pipe sealing assembly, thereby closing the branch pipes, thus increasing the negative pressure value in the remaining branch pipes. When the size of the material to be cut changes further, all air inlet pipes on a certain zoned air chamber can be closed, thus increasing the negative pressure value in the remaining zoned air chambers. This makes the negative pressure control of the cutting bed more hierarchical and sequential, achieving synchronous improvement in gas control in the main pipe and branch pipes, with the negative pressure value increasing by approximately 20%.

[0016] 2. The vacuum adsorption structure of the cutting bed and the cutting bed involved in this invention, when the cutting blade cuts the material, the air inlet pipes on different independent areas can open and close accordingly with the movement of the cutting blade, thereby achieving a greater negative pressure adsorption force on the material at the cutting position of the cutting blade.

The micro-blowing component silencer box is provided with a silencer pipe, and the silencer pipe includes a U-shaped tube body and a silencer air outlet. The silencer pipe is wound in a spiral layout through the U-shaped tube body, which can reduce the noise by about 5%, improve the environment, and enhance the customer's experience of using the machine.

[0026] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0027] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0028] like Figures 1-5As shown, the present invention provides a vacuum adsorption structure for a cutting bed, which is applied in a cutting bed; the cutting bed includes a cutting table, which is composed of several honeycomb panels 1; several ventilation holes are opened on the honeycomb panels 1, and several partitions are arranged on the bottom surface of the honeycomb panels 1, which divide the honeycomb panels 1 into several independent areas; the vacuum adsorption structure includes a vacuum pump 2, a micro-blowing component silencer box 6, a main pipe 3, several partition air chambers 4, and several branch pipes 5. The vacuum pump 2 is connected to the main pipe 3 through the micro-blowing component silencer box 6, the several partition air chambers 4 are connected to the main pipe 3, one end of the several branch pipes 5 is respectively connected to the several partition air chambers 4, and the other end of the several branch pipes 5 is arranged in an independent area on the lower side of the honeycomb panels 1.

[0029] The vacuum adsorption structure of the cutting bed involved in this invention has several partitioned air chambers 4 connected to the main pipe 3, and one end of the branch pipe 5 connected to the partitioned air chambers 4, and the other end set in an independent area below the honeycomb plate 1. That is, the main pipe 3 passes through the partitioned air chambers 4 and then through the branch pipe 5 to achieve vacuum adsorption of the cut material on the honeycomb plate 1 in an independent area. If no material is cut in the honeycomb panel 1 of an independent area above a certain branch pipe 5 (or the material has been cut in that area, or the cutter is cutting other areas in that independent area but has not yet cut the material there), the branch pipe 5 of that independent area can be closed, thereby increasing the negative pressure value in the remaining areas; if no material is cut in the honeycomb panel 1 of an independent area above several branch pipes 5 on a certain partition air tank 4 (or the material in that independent area has been cut in all areas, or the cutter is cutting other independent areas but has not yet cut the material there), the partition air tank 4 can be closed, thereby increasing the negative pressure value in the remaining partition air tank 4. By using the partition air tank 4 and branch pipes 5, the negative pressure control of the cutting bed has a sense of hierarchy and order, achieving synchronous improvement of gas control in the main pipe 3 and branch pipes 5, which can effectively improve the negative pressure value.

[0030] Preferred, such as Figure 2 , Figure 3 , Figure 4As shown, the partitioned air tank 4 includes an outer shell 401, an inner cavity 402, an outlet pipe 403, several inlet pipes 404, and several inlet pipe sealing assemblies. The inner cavity 402 is disposed within the outer shell 401. The outlet pipe 403 and several inlet pipes 404 are fixed to the outer shell 401, and one end of the outlet pipe 403 and several inlet pipes 404 is connected to the inner cavity 402. The ends of several inlet pipes 404 away from the inner cavity 402 are connected to several branch pipes 5. The outlet pipe 403 is away from the inner cavity 402. One end is connected to the main pipe 3; the intake pipe blocking assembly is used to control the opening and closing of the intake pipe 404; the intake pipe blocking assembly includes an intake pipe blocking cylinder 405 and an intake pipe plug 406. The intake pipe blocking cylinder 405 is installed on the air bag shell 401, and the intake pipe plug 406 is installed on the piston shaft of the intake pipe blocking cylinder 405. The intake pipe plug 406 is located in the air bag inner cavity 402 and can move along the piston shaft of the intake pipe blocking cylinder 405 to block the intake pipe 404; the number of intake pipes 404 and intake pipe blocking assemblies are the same and correspond one-to-one.

[0031] Furthermore, such as Figures 1-4 As shown, in this embodiment, the cutting bed is composed of two honeycomb panels 1 connected together. The two honeycomb panels 1 are divided into a large honeycomb panel 101 and a small honeycomb panel 102. Both the large honeycomb panel 101 and the small honeycomb panel 102 contain three independent areas, for a total of six independent areas. Therefore, in this embodiment, the number of partition air bags 4 is three. Each partition air bag 4 has two air inlet pipes 404 and one air outlet pipe 403, for a total of six air inlet pipes 404, thereby realizing the control of the six independent areas.

[0032] For ease of description, only the structure of one partition gas reservoir 4 will be described in detail. The structures of the other partition gas reservoirs 4 are the same and will not be described again. The structure of one partition gas reservoir 4 is as follows:

[0033] like Figures 1-3As shown, the two air inlet pipes 404 on a partitioned air tank 4 are the first air inlet pipe and the second air inlet pipe, respectively. The first air inlet pipe is used to control an independent area below the large honeycomb panel 101, and the second air inlet pipe is used to control an independent area below the small honeycomb panel 102. An air outlet pipe 403 is connected to the main pipe 3. The air tank shell 401 is rectangular in shape. The first air inlet pipe and the second air inlet pipe are respectively located on opposite outer surfaces of the air tank shell 401. The air inlet pipe sealing cylinder 405, which controls the opening and closing of the first air inlet pipe, is located on the side of the air tank shell 401 opposite to the first air inlet pipe. The air inlet pipe sealing cylinder 405 drives the air inlet pipe plug 406 to seal the first air inlet pipe through a piston shaft. Similarly, the air inlet pipe sealing cylinder 405, which controls the opening and closing of the second air inlet pipe, is located on the side of the air tank shell 401 opposite to the second air inlet pipe. The air inlet pipe sealing cylinder 405 drives the air inlet pipe plug 406 to seal the second air inlet pipe through a piston shaft. When the first intake pipe is blocked, the negative pressure in the second intake pipe and the remaining partition air tank 4 increases; when the second intake pipe is blocked, the negative pressure in the first intake pipe and the remaining partition air tank 4 increases; when both the first and second intake pipes are blocked, the negative pressure in the remaining partition air tank 4 increases, thus achieving a sense of hierarchy and order in the negative pressure control of the main pipe 3 and the branch pipe 5.

[0034] Preferred, such as Figure 2 , Figure 3 As shown, the branch pipe 5 includes several bends 502, one end of which is connected to several air inlet pipes 404, and the other end is located in an independent area below the honeycomb panel 1. Furthermore, the branch pipe 5 also includes several multi-way connectors 501, through which the bends 502 can be connected to the air inlet pipes 404. The bends 502 are made of PVC flexible plastic tubing.

[0035] In this embodiment, since the first air inlet pipe is used to control an independent area below the large honeycomb panel 101, and the second air inlet pipe is used to control an independent area below the small honeycomb panel 102, and both the first and second air inlet pipes are connected to the same partitioned air bag 4, the negative pressure is the same. To ensure better adsorption in the independent area of ​​the large honeycomb panel 101, a multi-port connector 501 is connected to the first air inlet pipe, and several bends 502 are set on the multi-port connector 501, which expands the adsorption area of ​​the bends 502 and ensures the adsorption uniformity in the independent area of ​​the large honeycomb panel 101. Since the independent area below the small honeycomb panel 102 is smaller, only one bend 502 is needed to achieve adsorption uniformity in this independent area, so only one bend 502 is set on the second air inlet pipe. In this embodiment, the multi-way connector 501 is a tee connector, with two bends 502 connected to the tee connector. That is, there are a total of three bends 502 on one partitioned air chamber 4. Two bends 502 are located in an independent area below the large honeycomb panel 101, and the other bend 502 is located in an independent area below the small honeycomb panel 102. The three partitioned air chambers 4 have a total of nine bends 502. In other embodiments, the multi-way connector 501 can be determined based on the area of ​​the independent area below the honeycomb panel 1.

[0036] Preferred, such as Figure 2 , Figure 5 As shown, the micro-blowing component silencer box 6 includes a box body 607, a vacuum pump suction pipe 601, a vacuum pump outlet pipe 603, a silencer pipe 604, a return air pipe 605, and a return air pipe sealing component 606. The vacuum pump suction pipe 601 and the vacuum pump outlet pipe 603 are both installed in the box body 607. One end of the vacuum pump suction pipe 601 is connected to the main pipe 3, and the other end is connected to the vacuum pump 2. One end of the vacuum pump outlet pipe 603 is connected to the vacuum pump 2, and the other end is connected to the return air pipe 605. The end of the return air pipe 605 away from the vacuum pump outlet pipe 603 is connected to the vacuum pump suction pipe 601. One end of the silencer pipe 604 is connected to the vacuum pump outlet pipe 603, and the other end is open to the atmosphere. The return air pipe sealing component 606 is used to control the opening and closing of the return air pipe 605.

[0037] Preferred, such as Figure 5 As shown, the return air duct sealing assembly 606 includes a return air duct sealing cylinder and a return air duct plug. The return air duct sealing cylinder is installed on the vacuum pump outlet duct 603, and the return air duct plug is installed on the piston shaft of the return air duct sealing cylinder. The return air duct plug can block the return air duct 605 under the movement of the piston shaft of the return air duct sealing cylinder.

[0038] In this embodiment, as Figures 1-5As shown, the vacuum pump suction pipe 601 and the vacuum pump outlet pipe 603 are arranged parallel to each other in the housing 607, and the return air pipe 605 connects the vacuum pump suction pipe 601 and the vacuum pump outlet pipe 603.

[0039] When the return air duct 605 is blocked by the return air duct blocking component 606, the gas at the honeycomb panel 1 enters the vacuum pump suction pipe 601 through the branch pipe 5, the partition air manifold 4, and the main pipe 3, and then enters the vacuum pump outlet pipe 603 through the vacuum pump 2. After being silenced by the silencer pipe 604, it is discharged. At this time, the vacuum pump 2 is in the positive suction state.

[0040] When the return air duct 605 is not blocked by the return air duct sealing component 606, the gas at the honeycomb panel 1 enters the vacuum pump suction duct 601 through the branch pipe 5, the partition air manifold 4, and the main pipe 3, and then enters the vacuum pump outlet duct 603 through the vacuum pump 2. Part of it is discharged after being silenced by the silencer pipe 604, and the other part returns to the vacuum pump suction duct 601 through the return air duct 605. A part of the gas that returns to the vacuum pump suction duct 601 returns to the vacuum pump 2, and the other part of the gas that returns to the vacuum pump suction duct 601 cancels the negative pressure gas in the main pipe 3, the partition air manifold 4, and the branch pipe 5, thereby achieving back-blowing of the honeycomb panel 1.

[0041] Preferred, such as Figure 2 As shown, the silencer pipe 604 includes a U-shaped pipe body 6041 and a silencer outlet. The U-shaped pipe body 6041 is disposed in the housing 607. One end of the U-shaped pipe body 6041 is connected to the vacuum pump outlet pipe 603, and the other end of the U-shaped pipe body 6041 is connected to the atmosphere through the silencer outlet. In this embodiment, the U-shaped pipe body 6041 and the vacuum pump suction pipe 601 are perpendicular to each other in space, and the U-shaped pipe body 6041 is disposed above the vacuum pump suction pipe 601. The U-shaped pipe body 6041, the vacuum pump suction pipe 601, and the vacuum pump outlet pipe 603 are all integrated into the housing 607, reducing the space occupied by the equipment.

[0042] Preferred, such as Figure 5 As shown, the micro-blowing component silencer box 6 also includes a pressure relief valve assembly 602, which is disposed in the vacuum pump suction pipe 601 and is used to relieve the pressure of the gas in the vacuum pump suction pipe 601.

[0043] In this embodiment, when the vacuum pump 2 is working, a vacuum or negative pressure is formed in the vacuum pump suction pipe 601, and a slight positive pressure is formed in the vacuum pump outlet pipe 603.

[0044] After the forward suction process of vacuum pump 2 ends, it immediately reverses to start the reverse blowing process. The return air pipe 605 connects the vacuum pump outlet pipe 603 and the vacuum pump suction pipe 601. Because the main pipe 3, the partition air manifold 4, and the sub-pipes 5 are relatively long, the vacuum degree inside the pipes is still lower than the external air pressure, and the cut material will still be adsorbed on the honeycomb panel 1. After a period of return air, the slightly positive pressure gas enters the vacuum pump suction pipe 601 from the vacuum pump outlet pipe 603 to counteract the vacuum degree in the vacuum pump suction pipe 601. The vacuum degree inside the pipe will be equal to or slightly higher than the external air pressure, so that the cut material can be free from adsorption force on the honeycomb panel 1. The purpose of setting the pressure relief valve assembly 602 is to make the vacuum degree inside the pipe equal to the external air pressure quickly, thereby shortening the delay of the reverse blowing.

[0045] Additionally, in this application, the back-blowing air force can be controlled by adjusting the opening degree of the pressure relief valve assembly 602. When the pressure relief valve assembly 602 is not open, the vacuum degree in the vacuum pump suction pipe 601 is relatively high. The positive pressure gas in the vacuum pump outlet pipe 603 enters the vacuum pump suction pipe 601 through the return air pipe 605, mainly to balance the vacuum degree in the vacuum pump suction pipe 601, that is, to offset part of the adsorption force on the cut material. However, since the vacuum pump 2 is continuously working, it is possible that even if part of the adsorption force is offset, the cut material will still be adsorbed on the honeycomb panel 1, only the adsorption force is reduced.

[0046] When the pressure relief valve assembly 602 is partially opened, the vacuum degree in the vacuum pump suction pipe 601 decreases. The positive pressure gas in the vacuum pump outlet pipe 603 enters the vacuum pump suction pipe 601 through the return air pipe 605 to first balance the vacuum degree in the vacuum pump suction pipe 601. Then the remaining part will enter the independent area through the main pipe 3, the partition air bag 4, and the sub-pipe 5, completely canceling the adsorption force of the cut material. At this time, the cut material is neither subjected to suction nor blowing force on the honeycomb plate 1.

[0047] When the pressure relief valve assembly 602 is mostly open, the vacuum degree in the vacuum pump suction pipe 601 is further reduced. The positive pressure gas in the vacuum pump outlet pipe 603 enters the vacuum pump suction pipe 601 through the return air pipe 605 to first balance the vacuum degree in the vacuum pump suction pipe 601. Then the remaining part will enter the independent area through the main pipe 3, the partition air manifold 4, and the sub-pipe 5. The remaining positive pressure gas is greater than the adsorption force of the material. At this time, the material is only subjected to blowing force on the honeycomb plate 1.

[0048] When the pressure relief valve assembly 602 is fully open, the state is the same as when the pressure relief valve assembly 602 is mostly open, the only difference being that the material being cut experiences a greater blowing force. However, in this application, since a silencer pipe 604 is connected to the vacuum pump outlet pipe 603, the gas pressure in the return air pipe 605 is basically equal to the external pressure. That is, when the pressure relief valve assembly 602 is mostly open or fully open, the blowing force on the material will not be greater than the material's suction force. In other words, when the pressure relief valve assembly 602 is mostly open or fully open, the state of the material is basically the same as the state where it is neither subjected to suction nor blowing force.

[0049] In this embodiment, the honeycomb panel 1 is made of aluminum plate.

[0050] To achieve the above or other objectives, the present invention also discloses a cutting bed, including the vacuum adsorption structure of the cutting bed described above.

[0051] The vacuum adsorption structure and cutting bed of the present invention have the following working steps:

[0052] S1: According to the appendix Figures 1-5 The descriptions of the above-mentioned components are used to describe the production, manufacturing, and installation of each component.

[0053] S2: Place the cut material on the honeycomb panel 1, start the vacuum pump 2, and the vacuum pump 2 generates negative pressure suction. The negative pressure suction appears in an independent area below the honeycomb panel 1 through the vacuum pump suction pipe 601, the main pipe 3, several partition air bags 4, the branch pipes 5, and several bends 502, and then achieves negative pressure vacuum adsorption on the cut material on the honeycomb panel 1. The cut material is adsorbed on the honeycomb panel 1, which also realizes the positive air suction function of the vacuum pump 2. The air sucked in by the vacuum pump suction pipe 601 is transferred by the vacuum pump 2 and enters the vacuum pump outlet pipe 603. After being silenced by the silencer pipe 604, it is discharged into the atmosphere (at this time, the return air pipe 605 in the silencer box 6 of the micro-blowing component is in a blocked state). Then the cutting blade of the cutting bed cuts the cut material.

[0054] S3: When the size of the cut material changes (e.g., the size becomes smaller, and it is not necessary to vacuum all bends 502), the operator controls the air inlet pipe sealing cylinder 405 on a certain section air tank 4 to operate. The operation of the air inlet pipe sealing cylinder 405 drives the air inlet pipe plug 406 to seal the air inlet pipe 404 through the piston shaft. That is, the bend 502 connected to the air inlet pipe 404 is blocked. The independent area under the responsibility of the bend 502 does not perform vacuum adsorption on the cut material, and the negative pressure of the remaining independent area increases. When the size of the cut material is even smaller, the operator controls all the air inlet pipe sealing cylinders 405 on a certain section air tank 4 to operate. The independent areas under the responsibility of the section air tank 4 do not perform vacuum adsorption on the cut material, thereby increasing the negative pressure of the remaining independent areas. By controlling the opening and closing state of the air inlet pipe sealing cylinders 405, the negative pressure control in the main pipe 3 and the branch pipe 5 is made more hierarchical and orderly.

[0055] S4: After the cutting blades on the cutting bed finish cutting the material, the return air pipe sealing cylinder in the silencer box 6 of the micro-blowing component operates. The return air pipe sealing cylinder drives the return air pipe plug to open the return air pipe 605 through the piston shaft. The vacuum pump outlet pipe 603 is connected to the vacuum pump suction pipe 601 through the return air pipe 605. At this time, the gas at the honeycomb panel 1 enters the vacuum pump 2 through the branch pipe 5, the partition air bag 4, the main pipe 3, and the vacuum pump suction pipe 601. The air drawn in by the vacuum pump suction pipe 601 is transferred by the vacuum pump 2 and enters part of the vacuum pump outlet pipe 603. One portion of the gas is discharged into the atmosphere after being silenced by the silencer pipe 604, while the other portion returns to the vacuum pump suction pipe 601 through the return air pipe 605. Some of the gas that returns to the vacuum pump suction pipe 601 then returns to the vacuum pump 2. The other portion of the gas that returns to the vacuum pump suction pipe 601 cancels out the negative pressure gas in the main pipe 3, the partition air tank 4, and the sub-pipe 5, thus achieving back-blowing of the honeycomb panel 1. When the vacuum pump 2 achieves back-blowing of the honeycomb panel 1, the negative pressure adsorption force on the cut material on the honeycomb panel 1 decreases, and the operator can remove the cut material from the honeycomb panel 1.

[0056] Preferably, in step S4, when the vacuum pump 2 performs back-blowing, the pressure relief valve assembly 602 in the micro-blowing component silencer box 6 can be opened as needed, and the opening degree of the pressure relief valve assembly 602 can be adjusted as needed, thereby adjusting the back-blowing force through the opening degree of the pressure relief valve assembly 602.

[0057] Preferably, in this embodiment, the pressure relief valve assembly 602, the return air duct sealing cylinder, and the intake air duct sealing cylinder 405 can all be controlled by the control system. The control system can cooperate with the PC terminal to realize intelligent control by the operator, making the control more precise and intelligent. Thus, in step S2, when the cutter cuts the material, the control system can control the intake air duct sealing cylinder 405 to intelligently open and close following the movement trajectory of the cutter, ensuring that the material at the cutting point is subjected to a large negative pressure adsorption force.

[0058] The present invention relates to a vacuum adsorption structure for a cutting bed and a cutting bed in which multiple partitioned air chambers 4 are provided, each partitioned air chamber 4 is provided with several air inlet pipes 404, and each air inlet pipe 404 is provided with an air inlet pipe sealing component for controlling the opening and closing of the air inlet pipe 404; each air inlet pipe 404 is provided with several bends 502, and each bend 502 realizes negative pressure adsorption control of an independent area of ​​the honeycomb panel 1. In this way, the control of the gas in the main pipe 3 and the sub-pipes 5 by controlling the air inlet pipe sealing component is more hierarchical and orderly, and the gas in the main pipe 3 and the sub-pipes 5 is simultaneously increased, and the negative pressure value can be increased by about 20%. The silencer pipe 604 adopts a U-shaped pipe body 6041 with a winding layout, which can reduce the noise by about 5 decibels, improve the environment, and enhance the customer's experience of using the machine. The system is equipped with a return air duct 605 and a return air duct sealing component 606. The return air duct 605 is opened and closed by the return air duct sealing component 606, thereby realizing the back-blowing function of the vacuum pump 2. At the same time, a pressure relief valve component 602 is provided, which can control the strength of the back-blowing air by controlling the opening degree of the pressure relief valve component 602.

[0059] This invention can increase the gas value in the main pipe 3 (which includes three zoned air bags 4) and control the gas value in the sub-pipes 5, thereby increasing the negative pressure value of the gas. This solves the problem that non-breathable fabrics are difficult to absorb during customer cutting. Moreover, after zoned control, the gas can be concentrated in a specific area, and the maximum negative pressure value of this area can be increased, further enhancing the adsorption capacity.

[0060] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
