Description

Technical Field

[0001] This utility model relates to the field of flexible material processing technology, specifically to a negative pressure adsorption device for flexible material cutting equipment. Background Technology

[0002] Flexible materials mostly refer to fabrics, membranes, and woven materials, which need to be cut into specified sizes during processing to meet user requirements. When cutting these materials, in order to ensure the stability of the cutting, bottom openings are used, combined with negative pressure to position the flexible materials.

[0003] Currently, utility model patent CN209937007U discloses a CNC vibratory knife cutting machine for flexible materials with vacuum adsorption function, including: a machine tool body, an X-axis, a Y-axis, and a Z-axis; the Y-axis is fixedly installed on the machine tool body; the X-axis is slidably installed on the Y-axis above the machine tool body; the Z-axis is slidably installed on the X-axis above the machine tool body, used to complete the operation of cutting flexible products; the machine tool body includes: a frame, a vacuum adsorption table, a vacuum adsorption mechanism, and sheet metal parts set on the outer surface of the frame; the vacuum adsorption mechanism is installed on the frame, the vacuum adsorption table is installed on the frame above the vacuum adsorption mechanism, the Y-axis is installed parallel to the vacuum adsorption table on the machine tool, and the vacuum adsorption table is driven by the vacuum adsorption mechanism to achieve the operation of adsorbing products; the pressure is used to firmly adsorb the product on the vacuum adsorption table, ensuring that the product does not slip on the worktable, does not damage the product surface, and improves the product yield.

[0004] In existing cutting equipment, to ensure the stability of flexible materials, the adsorption and cutting platform is mostly a single unit, allowing the flexible material to be laid flat on the platform for cutting by the cutting blade. Since the flexible material adheres to the cutting plane during cutting, the stroke accuracy of the cutting blade needs precise control to prevent scratching the platform. While the above solutions, using a three-axis drive adjustment method and a vibrating blade cutting method, can avoid damaging the product surface, if the vertical adjustment device has a stroke error, it can still scratch the platform and even cause blade wear, affecting subsequent cutting quality. To address this issue, this application provides a negative pressure adsorption device for flexible material cutting equipment to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a negative pressure adsorption device for flexible material cutting equipment, in order to solve the problem that the cutting equipment in the prior art has high requirements for vertical driving accuracy during use, which easily leads to damage between the cutting tool and the adsorption plane due to friction.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a negative pressure adsorption device for a flexible material cutting device, including a housing with an open top, and a three-axis cutting mechanism that can move on the X, Y and Z axes on the housing; The casing is equipped with a sealing element, which forms a negative pressure space with only a top opening. An adsorption mechanism is provided on the outside of the casing, which is connected to the inside of the negative pressure space. A pressure relief element is also provided on the outside of the casing, which is connected to the inside of the negative pressure space. The housing is equipped with a drive mechanism, and the drive mechanism is equipped with several support members that are driven by the drive mechanism to move along a circular path. The support member is provided with a number of support rods, which are distributed in a dotted manner on the support member.

[0007] The above technical solution allows the flexible material placed on the support rod to achieve negative pressure adsorption and positioning through the gaps between the support components; and in the point-support state, it facilitates the normal cutting work of the three-axis cutting mechanism.

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

[0009] Furthermore, the adsorption mechanism includes two vacuum pumps located on the outside of the housing. Each vacuum pump has an extraction pipe, the end of which is fixed to the housing and connected to the interior of the negative pressure space.

[0010] The above technical solution enables the vacuum pump to perform vacuuming on the negative pressure space through the suction pipe.

[0011] Furthermore, the support member includes a support steel, a fixing plate abutting against the support steel, and a support rod fixed to the fixing plate in a point-like manner; The support steel is hollow, and a pad is slidably connected inside the support steel. Two locking plates are provided on the outside of the fixing plate. Several bolts are passed between the locking plates, the pad and the top of the support steel, and nuts are threaded on the outside of the bolts.

[0012] The above technical solution enables the locking plate, pad, and supporting steel to be connected and positioned.

[0013] Furthermore, the sealing element includes a sealing plate one and a sealing plate three fixed inside the housing, and a sealing plate two is fixed between the opposite sides of the sealing plate one and the sealing plate three. The space formed by the sealing plate 1, sealing plate 2, and sealing plate 3 with the interior of the casing is the negative pressure space.

[0014] The above technical solution enables the formation of a space inside the casing with an opening only at the top, facilitating subsequent negative pressure adsorption.

[0015] Furthermore, the drive mechanism is located between the opposite sides of sealing plate one and sealing plate three. The drive mechanism includes a drive component located on the outside of the housing, and two drive shafts rotatably connected to the inside of the housing via bearings. Two sprocket conveying modules are provided between the outer sides of the two drive shafts.

[0016] The above technical solution enables the drive mechanism to perform transmission work in a negative pressure space.

[0017] Furthermore, the driving component includes a servo motor and a reducer. The output shaft of the servo motor is connected to the input shaft of the reducer, and the output shaft of the reducer passes through the outside of the housing and is fixed to the end of the corresponding drive shaft.

[0018] The above technical solutions can achieve efficient power delivery.

[0019] Furthermore, each of the two sprocket conveying modules has several connecting plates on its opposite side, and the supporting steel is detachably connected between the tops of the corresponding two connecting plates.

[0020] The above technical solution enables the sprocket conveyor module to drive the support steel to move.

[0021] Furthermore, the pressure relief component includes several pressure relief pipes located outside the housing, which are connected to the interior of the negative pressure space, and are equipped with pressure relief valves that are connected to the interior of the pressure relief pipes.

[0022] The above technical solution enables the negative pressure space to be connected to the outside world through the pressure relief valve.

[0023] Furthermore, the fixing plate has several connecting holes, and the pad and the supporting steel both have several connecting openings, with the positions of the connecting openings corresponding to the connecting holes.

[0024] The above technical solution increases the number of negative pressure adsorption points, thereby producing a more stable adsorption and positioning effect on flexible materials.

[0025] Furthermore, the housing is provided with several crossbars, and several flow strips are provided between the tops of the crossbars, with the flow strips abutting against the bottom of the supporting steel.

[0026] Through the above technical solution, the smooth strip can provide auxiliary support to the supporting steel, enabling it to move smoothly.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The negative pressure space formed by the sealing plate 1, sealing plate 2, and sealing plate 3 and the housing enables the adsorption and positioning of the flexible material placed on the adsorption mechanism. The connecting holes and openings increase the space for communication, thereby further improving the stability of the negative pressure positioning. 2. By utilizing the principle of multi-point surface formation, the bottom of the flexible material can be supported at multiple points. This provides stable support while allowing the cutting tool of the triaxial cutting mechanism to pass through normally between the points, greatly reducing friction between the cutting tool and the support surface and protecting the structure. Through the cooperation of the pressure relief pipe and pressure relief valve, the negative pressure space can be quickly connected to the outside, allowing the internal and external air pressures to reach a balance quickly, thereby releasing the adsorption and positioning of the flexible material and improving overall efficiency.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Example: Reference Figure 1 A negative pressure adsorption device for flexible material cutting equipment includes a housing 1 with an open top, a three-axis cutting mechanism 3 that can move along the X, Y, and Z axes on the housing 1; a sealing element is provided inside the housing 1, forming a negative pressure space with only an open top; an adsorption mechanism 2 is provided on the outside of the housing 1, which is connected to the inside of the negative pressure space; a pressure relief element is also provided on the outside of the housing 1, which is connected to the inside of the negative pressure space; a driving mechanism is provided inside the housing 1, and several support members are provided on the driving mechanism to move along a circular path; several support rods 27 are provided on the support members, which are distributed in a point-like manner on the support members.

[0033] It should be noted that the three-axis cutting mechanism 3 is a commonly used cutting device in the prior art. It can move on the X, Y, and Z axes and can be controlled by linear drive components such as lead screws and hydraulic cylinders. It is a publicly available technology, so it will not be described in detail.

[0034] refer to Figure 2 and Figure 3 The adsorption mechanism 2 includes two vacuum pumps 21 located on the outside of the housing 1. Each vacuum pump 21 is equipped with a suction pipe 22. The end of the suction pipe 22 is fixed to the housing 1. The suction pipe 22 is connected to the inside of the negative pressure space, so that the vacuum pump 21 can perform vacuum treatment on the negative pressure space through the suction pipe 22, and then use the effect of negative pressure to adsorb and position the flexible material.

[0035] refer to Figure 4 and Figure 7The support includes a support steel 25, on which a fixed plate 26 abuts. Support rods 27 are fixed to the fixed plate 26 in a point-like manner. Through the point-like arrangement, the bottom of the flexible material can be supported by the multi-point surface support. This method allows the tool to pass over the point structure for cutting normally and ensures the stability of the support. The support steel 25 is hollow, and a pad 61 is slidably connected inside the support steel 25. Two locking pieces 62 are provided on the outside of the fixed plate 26. Several bolts are passed between the locking pieces 62, the pad 61 and the top of the support steel 25. Nuts are threaded on the outside of the bolts, so that the locking pieces 62, the pad 61 and the support steel 25 can be connected and positioned by bolts and nuts.

[0036] refer to Figure 2 The sealing components include a sealing plate 41 and a sealing plate 43 fixed inside the housing 1. A sealing plate 42 is fixed between the opposite sides of the sealing plate 41 and the sealing plate 43. The space formed by the sealing plate 41, the sealing plate 42 and the sealing plate 43 and the interior of the housing 1 is a negative pressure space, which allows a space with an opening only at the top to be formed inside the housing 1, facilitating subsequent negative pressure adsorption.

[0037] refer to Figure 3 The drive mechanism is located between the opposite sides of the sealing plate 41 and the sealing plate 43. The drive mechanism includes a drive component 51 located on the outside of the housing 1, and two drive shafts 52 rotatably connected to the housing 1 via bearings. Two sprocket conveying modules 53 are provided between the outer sides of the two drive shafts 52, so that the drive mechanism can perform transmission work in the negative pressure space and drive the support steel 25 to move in the negative pressure space, so that the flexible material can achieve effective adsorption and positioning effect.

[0038] refer to Figure 3 The drive unit 51 includes a servo motor and a reducer. The output shaft of the servo motor is connected to the input shaft of the reducer. The output shaft of the reducer passes through the outside of the housing 1 and is fixed to the end of the corresponding drive shaft 52, which can achieve a high-efficiency power supply effect.

[0039] refer to Figure 1 and Figure 3 Each of the two sprocket conveying modules 53 has several connecting pieces 54 on its opposite side. The support steel 25 is detachably connected between the tops of the corresponding two connecting pieces 54, so that the sprocket conveying module 53 can drive the support steel 25 to move.

[0040] It should be noted that the sprocket conveying module 53 is a conveying device for sprockets and chains. It is driven by the coaxial drive of the drive shaft 52, so that two corresponding sprockets drive one chain for transmission. This is a commonly used structure in existing transmission technology, and all of them are existing technologies, so we will not go into too much detail.

[0041] It should also be noted that the connecting piece 54 is located on the opposite side of the two chains, so that it can be moved by being driven by the chains.

[0042] In use, flexible materials are stacked between the tops of support rods 27, and a thin film is laid on top of the flexible materials. Vacuum pump 21 is started, and gas in the negative pressure space is extracted through suction pipe 22 to form a negative pressure space inside. The film is then adsorbed through the gaps between the structures. Under the action of negative pressure, the film presses down on the flexible materials, making them stably placed between the tops of support rods 27. The three-axis cutting mechanism 3 is started to cut the adsorbed and positioned flexible materials. The drive component 51 drives the support steel 25 to move through the sprocket conveying module 53, thereby conveying the flexible materials.

[0043] refer to Figure 3 The pressure relief component includes several pressure relief pipes 23 located outside the housing 1. The pressure relief pipes 23 are connected to the interior of the negative pressure space. The pressure relief pipes 23 are equipped with pressure relief valves 24 that are connected to the interior of the negative pressure space, so that the negative pressure space can be connected to the outside through the pressure relief valves 24.

[0044] When in use, opening the pressure relief valve 24 allows the negative pressure space to connect with the outside world, quickly bringing the internal and external pressures into a balanced state and improving the efficiency of releasing the positioning.

[0045] refer to Figure 5 and Figure 6 The fixed plate 26 has several connecting holes 28, and the pad 61 and the supporting steel 25 each have several connecting ports 29. The positions of the connecting ports 29 and the connecting holes 28 are corresponding. The connecting ports 29 and the connecting holes 28 allow airflow to pass through, thereby increasing the number of negative pressure adsorption points and producing a more stable adsorption and positioning effect on the flexible material.

[0046] refer to Figure 1 and Figure 3 The housing 1 is provided with several crossbars 71, and several smooth strips 72 are provided between the tops of the crossbars 71. The smooth strips 72 abut against the bottom of the support steel 25. The smooth strips 72 can provide auxiliary support for the support steel 25 and the flexible material placed on top of it, and the friction is small, so that the support steel 25 can move smoothly.
