[0002] At present, flexible materials such as plastic films and cloths are indispensable materials in our daily life and production. After the existing cutting device cuts the rolled flexible materials, such as cloths and films, it is necessary to manually pull the head of the flexible material and pass it through the cutting assembly. On the one hand, there are great safety hazards in the process of repeated pulling. On the other hand, after manual pulling, the position of the flexible material and the tension of the flexible material need to be re-positioned, which is cumbersome. Summary of the invention

[0003] The invention provides a numerically controlled cutting device for flexible materials, which can overcome certain defects of the prior art.

[0004] According to the present invention, a numerical control cutting device for flexible materials comprises a device body, the device body comprises a machine body, a horizontally arranged mounting plate and a cutting assembly arranged above the mounting plate are arranged on the machine body, feeding assemblies are arranged at both ends of the mounting plate perpendicular to the cutting assembly, the feeding assembly comprises a conveyor belt and a plurality of positioning assemblies rotatably arranged on the outer wall of the conveyor belt, and the positioning assemblies are used to limit the two sides of the flexible material; A cutting area is formed between adjacent positioning components, and the mounting plate cooperates with the cutting component to cut the flexible material in the cutting area.

[0005] The present invention discloses a CNC cutting device for flexible materials. By setting a feeding component, both sides of the flexible material and both ends of the cutting area can be accurately limited. While ensuring the cutting accuracy, the conveyor belt can also be rotated to allow the positioning component close to one side of the discharge roller to be transported to the other side of the cutting component. There is no need to manually pull the head of the flexible material through the cutting component, which improves the safety of the cutting process and does not need to readjust the position of the flexible material and the tension of the flexible material, thereby improving work efficiency.

[0006] It can be understood that the setting of the positioning component ensures the stability and accuracy of the flexible material during the cutting process, and avoids cutting errors caused by the deviation or shaking of the flexible material.

[0007] In addition, the device can also cut flexible materials that are not rolled, thereby increasing the application range of the device.

[0008] Preferably, the positioning assembly includes a rotating seat rotatably arranged at the conveyor belt, an inwardly recessed slide groove is formed on the top wall of the rotating seat, a slider is slidably provided inside the slide groove, an adjusting piece is provided on the top wall of the slider, a fastener is rotatably provided on the adjusting piece, and the fastener is used to cooperate with the slider to limit the position of the adjusting piece.

[0009] By coordinating the slider and the slide groove, the slider can move flexibly in the slide groove, thereby adjusting the position of the adjusting member, so that the positioning component can limit flexible materials of different widths, and lock its position by rotating the fastener, ensuring that the positioning component remains stable during the cutting process, and can flexibly adapt to various cutting requirements, thereby improving the versatility and practicality of the entire cutting device.

[0010] Preferably, a positioning portion is formed at the end of the adjusting member, a socket recessed inwardly is formed at one end of the positioning portion away from the fastener, a matching portion is formed at the bottom wall of the socket, a vertically arranged sliding cavity and an installation cavity arranged perpendicular to the sliding cavity are formed inside the positioning portion, a clamping member is slidably provided in the sliding cavity, the clamping member is used to cooperate with the matching portion to limit the flexible material, and a locking assembly is slidably provided in the installation cavity, the locking assembly is used to limit the clamping member.

[0011] Through the coordination setting of the clamping piece and the mating part, when the clamping piece is pressed downward and coordinated with the mating part, the flexible materials of different thicknesses can be tightly fixed to prevent them from moving, and the clamping piece can be locked by cooperating with the locking assembly to ensure that the clamping piece will not move accidentally during the cutting process.

[0012] Preferably, the clamping member includes a handle sliding in the sliding cavity, a fixed portion is formed on the outer wall of the handle, a plurality of protrusions are arranged at intervals on the outer wall of the handle above the fixed portion, and an insertion groove is formed between adjacent protrusions, a first spring is arranged between the fixed portion and the sliding cavity, the first spring is used to maintain the elastic force for pressing the fixed portion upward, a pressure plate arranged parallel to the mating portion is formed at one end of the handle passing through the bottom wall of the sliding cavity, and a pressing block is formed at one end of the pressure plate passing through the top wall of the sliding cavity.

[0013] Through the above structure, the user can quickly compress or release the flexible material through the pressing piece, thereby improving the convenience and efficiency of the operation.

[0014] It is understandable that the first spring is arranged between the fixed portion and the sliding cavity, providing a continuous upward elastic force for the handle, ensuring that the handle can automatically return to the initial position when no external force is applied, that is, the pressure plate does not contact the flexible material.

[0015] Preferably, the locking assembly includes a positioning piece slidably arranged in the installation cavity, one end of the positioning piece extending through the installation cavity into the sliding cavity is formed with a snap-fitting portion cooperating with the plug-in slot, the other end of the positioning piece extending through the installation cavity and located outside the installation cavity is formed with a pull ring, a fixing plate is formed on the outer wall of the positioning piece, a second spring is provided between the fixing plate and the inner wall of the installation cavity, and the second spring is used to maintain the elastic force that presses the fixing plate toward the sliding cavity.

[0016] The locking assembly realizes the locking and unlocking functions of the pressing member, especially the handle, through the cooperation between the clamping part of the positioning member and the plug-in slot. When the clamping part is inserted into the plug-in slot, the positioning member prevents the handle from sliding, thereby locking the pressing state; when the clamping part is pulled out of the plug-in slot, the handle resumes free sliding, unlocking the pressing state.

[0017] It is understandable that the second spring is disposed between the fixing plate and the inner wall of the installation cavity, providing the positioning member with a continuous compressive elastic force in the direction of the sliding cavity, ensuring that when there is no external force, the clamping portion of the positioning member tends to be inserted into the insertion slot, that is, to maintain a locked state. At the same time, when unlocking is required, the user can overcome the elastic force of the second spring by pulling the pull ring to disengage the clamping portion from the insertion slot.

[0018] Preferably, a restoring member is detachably provided on the side wall of the machine body, and the restoring member is used to adjust the positioning assembly to be parallel to the conveyor belt. A blocking portion is formed on the restoring member, and the blocking portion is used to block and guide the positioning assembly. A through groove is formed between the restoring member and the blocking portion for the positioning assembly to pass through.

[0019] Through the above structure, the used positioning component is parallel to the conveyor belt under the blocking guidance of the recovery member, avoiding interference with the flexible material when the positioning component is in a vertical state with the conveyor belt, and no manual adjustment is required, thereby improving the practicality of the device.

[0020] Preferably, a guide roller and a discharge roller are provided at the machine body, the discharge roller is used to install the rolled flexible material, and the guide roller is used to guide the flexible material.

[0021] The above structure facilitates the installation and deployment of the rolled flexible material, thereby improving the application scope of the device.

[0023] By closely cooperating the first fixing part and the second fixing part with the cutting seat, effective secondary compression and limiting are implemented on the flexible material in the cutting area, further avoiding the movement or deformation of the material, thereby ensuring the precision and quality of cutting.

[0024] Preferably, the cutting seat and the matching part are arranged at the same level, a cutting knife groove is formed on the top wall of the cutting seat, a fixed cutting knife matching with the movable cutting knife is arranged in the cutting knife groove, and a corresponding groove connected with the cutting knife groove and matching with the movable cutting knife is formed on the top wall of the cutting seat.

[0025] The movable cutter and the fixed cutter are arranged in coordination, so that shear forces in both the upper and lower directions are provided during cutting, thereby reducing the driving or influence of the cutter on the flexible material and improving the cutting accuracy.

[0026] A working method of a numerical control cutting device for flexible materials, which is used in a numerical control cutting device for flexible materials in an embodiment, comprises the following steps: Install the flexible material roll at the unwinding roller, pass the head of the flexible material roll through the guide roller and the cutting assembly in sequence and pull it to the required length; The positioning assembly is rotated to be perpendicular to the conveyor belt, and the two sides of the flexible material in the cutting area are limited by the positioning assemblies on both sides of the cutting assembly; Cutting is performed by the cutting assembly, the first fixing part and the second fixing part first press and position the two ends of the flexible material located in the cutting area, and then the second cylinder drives the movable cutter to press down and cooperate with the fixed cutter to cut the flexible material; After cutting is completed, the cutting assembly is lifted to its original position, and the conveyor belt rotates so that the positioning assembly on the side close to the discharge roller is transported to the other side of the cutting assembly. The user then releases the cut material head and cuts the required length next time. The positioning assembly after use is blocked and guided to a state parallel to the conveyor belt by the recovery part, and the cycle is repeated in sequence.

[0027] Through the above, efficient and accurate cutting of flexible materials is achieved, which not only improves the cutting efficiency, but also ensures the cutting quality, provides great convenience for users, and at the same time, makes the entire cutting process more automated.

DETAILED DESCRIPTION

[0037] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0038] Example 1 See also Figure 1-8The present embodiment provides a numerical control cutting device for flexible materials, which includes a device body 100, the device body 100 includes a body 110, the body 110 is provided with a horizontally arranged mounting plate 120 and a cutting assembly 130 arranged above the mounting plate 120, and the mounting plate 120 is provided with feeding assemblies 140 at both ends perpendicular to the cutting assembly 130, the feeding assembly 140 includes a conveyor belt 340 and a plurality of positioning assemblies 350 rotatably arranged at the outer wall of the conveyor belt 340, and the positioning assemblies 350 are used to limit the two sides of the flexible material; A cutting area is formed between adjacent positioning components 350 , and the mounting plate 120 cooperates with the cutting component 130 to cut the flexible material in the cutting area.

[0039] The positioning assembly 350 can be rotated 90°, specifically, along the conveying direction of the conveyor belt 340 to a direction perpendicular to the conveyor belt 340 .

[0040] A scale is formed on the top wall of the mounting plate 120 .

[0041] The present invention discloses a CNC cutting device for flexible materials. By setting a feeding component 140, both sides of the flexible material and both ends of the cutting area can be accurately limited. While ensuring the cutting accuracy, the conveyor belt 340 can also be rotated so that the positioning component 350 on one side close to the discharge roller 220 is transported to the other side of the cutting component 130. There is no need to manually pull the head of the flexible material through the cutting component 130, which improves the safety of the cutting process and does not need to readjust the position of the flexible material and the tension of the flexible material, thereby improving work efficiency.

[0042] It can be understood that the arrangement of the positioning assembly 350 ensures the stability and accuracy of the flexible material during the cutting process, and avoids cutting errors caused by the deviation or shaking of the flexible material.

[0043] In addition, the device can also cut flexible materials that are not rolled, thereby increasing the application range of the device.

[0044] In this embodiment, the positioning assembly 350 includes a rotating seat 510 rotatably arranged at the conveyor belt 340, and an inwardly recessed sliding groove 511 is formed at the top wall of the rotating seat 510. A slider is slidably provided inside the sliding groove 511, and an adjusting member 520 is provided at the top wall of the slider. A fastener 530 is rotatably provided at the adjusting member 520, and the fastener 530 is used to cooperate with the slider to limit the position of the adjusting member 520.

[0045] By cooperating with the slide block and the slide groove 511, the slide block can be flexibly moved in the slide groove 511, thereby adjusting the position of the adjustment member 520, so that the positioning assembly 350 can limit the flexible materials of different widths, and lock its position by rotating the fastener 530, thereby ensuring that the positioning assembly 350 remains stable during the cutting process, can flexibly adapt to various cutting requirements, and improves the versatility and practicality of the entire cutting device.

[0046] In this embodiment, a positioning portion 540 is formed at the end of the adjusting member 520, and an inwardly recessed socket 550 is formed at the end of the positioning portion 540 away from the fastener 530, and a matching portion is formed at the bottom wall of the socket 550. A vertically arranged sliding cavity 610 and an installation cavity 670 arranged perpendicular to the sliding cavity 610 are formed inside the positioning portion 540. A clamping member 560 is slidably provided in the sliding cavity 610, and the clamping member 560 is used to cooperate with the matching portion to limit the flexible material. A locking assembly 570 is slidably provided in the installation cavity 670, and the locking assembly 570 is used to limit the clamping member 560.

[0047] Through the matching setting of the clamping piece 560 and the matching part, when the clamping piece 560 is pressed downward and matched with the matching part, it can tightly fix the flexible materials of different thicknesses to prevent them from moving, and the clamping piece 560 can be locked in conjunction with the locking assembly 570 to ensure that the clamping piece 560 does not move accidentally during the cutting process.

[0048] In this embodiment, the clamping member 560 includes a handle 620 that slides in the sliding cavity 610, and a fixed portion is formed on the outer wall of the handle 620. A plurality of protrusions 630 are arranged at intervals on the outer wall of the handle 620 located above the fixed portion, and an insertion groove 640 is formed between adjacent protrusions 630. A first spring 660 is provided between the fixed portion and the sliding cavity 610, and the first spring 660 is used to maintain the elastic force that provides upward pressure on the fixed portion. A pressure plate 650 arranged parallel to the mating portion is formed at one end of the handle 620 that passes through the bottom wall of the sliding cavity 610, and a pressing block is formed at one end of the pressure plate 650 that passes through the top wall of the sliding cavity 610.

[0049] Through the above structure, the user can quickly compress or release the flexible material through the pressing member 560, thereby improving the convenience and efficiency of the operation.

[0050] It is understandable that the first spring 660 is arranged between the fixed portion and the sliding cavity 610, providing a continuous upward elastic force for the handle 620, ensuring that the handle 620 can automatically return to the initial position when there is no external force, that is, the pressure plate 650 does not contact the flexible material.

[0051] In this embodiment, the locking assembly 570 includes a positioning member 680 slidably arranged in the installation cavity 670, and one end of the positioning member 680 that passes through the installation cavity 670 and extends into the sliding cavity 610 is formed with a clamping portion that cooperates with the plug-in groove 640, and the other end of the positioning member 680 that passes through the installation cavity 670 and is located outside the installation cavity 670 is formed with a pull ring, and a fixing plate is formed on the outer wall of the positioning member 680, and a second spring 690 is provided between the fixing plate and the inner wall of the installation cavity 670, and the second spring 690 is used to maintain the elastic force that presses the fixing plate toward the sliding cavity 610.

[0052] The locking assembly 570 realizes the locking and unlocking functions of the pressing member 560, especially the pull handle 620, through the cooperation between the clamping portion of the positioning member 680 and the insertion slot 640. When the clamping portion is inserted into the insertion slot 640, the positioning member 680 prevents the pull handle 620 from sliding, thereby locking the pressing state; when the clamping portion is pulled out of the insertion slot 640, the pull handle 620 resumes free sliding, unlocking the pressing state.

[0053] It is understandable that the second spring 690 is disposed between the fixing plate and the inner wall of the installation cavity 670, providing a continuous compressive elastic force for the positioning member 680 toward the sliding cavity 610, ensuring that when there is no external force, the clamping portion of the positioning member 680 tends to be inserted into the insertion slot 640, that is, to maintain the locked state. At the same time, when unlocking is required, the user can overcome the elastic force of the second spring 690 by pulling the pull ring to disengage the clamping portion from the insertion slot 640.

[0054] In this embodiment, a recovery member 710 is detachably provided at the side wall of the body 110, and the recovery member 710 is used to adjust the positioning assembly 350 to be parallel to the conveyor belt 340. A blocking portion 720 is formed at the recovery member 710, and the blocking portion 720 is used to block and guide the positioning assembly 350. A through groove 730 is formed between the recovery member 710 and the blocking portion 720 for the positioning assembly 350 to pass through.

[0055] Through the above structure, the positioning component 350 after use is parallel to the conveyor belt 340 under the blocking guidance of the recovery member 710, avoiding interference with the flexible material when the positioning component 350 is in a vertical state with the conveyor belt 340, and no manual adjustment is required, thereby improving the practicality of the device.

[0056] In this embodiment, a guide roller 210 and a discharge roller 220 are provided at the machine body 110 . The discharge roller 220 is used to install the rolled flexible material, and the guide roller 210 is used to guide the flexible material.

[0057] The above structure facilitates the installation and deployment of the rolled flexible material, thereby improving the application scope of the device.

[0058] In this embodiment, the cutting assembly 130 includes a fixing frame 310 arranged on the body 110, and two first cylinders 320 are arranged on the fixing frame 310, and a mounting seat 330 is arranged between the telescopic ends of the two first cylinders 320, and an inwardly recessed mounting groove 450 is formed at the bottom wall of the mounting seat 330, and a second cylinder 460 is arranged inside the mounting groove 450, and a cutting knife seat is arranged at the telescopic end of the second cylinder 460, and a movable cutter 470 is detachably provided on the cutting knife seat, and a first fixing portion 480 and a second fixing portion 490 extending downward along both sides of the movable cutter 470 are formed on the bottom wall of the mounting seat 330, and the first fixing portion 480 and the second fixing portion 490 are used to cooperate with the cutting seat 410 to form a compression limit on the flexible material in the cutting area.

[0059] By closely cooperating with the first fixing portion 480 and the second fixing portion 490 and the cutting seat 410, effective secondary compression and limiting are implemented on the flexible material in the cutting area, further avoiding movement or deformation of the material, thereby ensuring the accuracy and quality of cutting.

[0060] In this embodiment, the cutting seat 410 is arranged at the same level as the matching part, and a cutting groove 420 is formed on the top wall of the cutting seat 410. A fixed cutting knife 430 that matches with the movable cutting knife 470 is arranged in the cutting groove 420. A corresponding groove 440 that is connected to the cutting groove 420 and matches with the movable cutting knife 470 is formed on the top wall of the cutting seat 410.

[0061] The movable cutter 470 and the fixed cutter 430 are arranged in coordination, so that shear forces in both the upper and lower directions are provided during cutting, thereby reducing the driving or influence of the cutter on the flexible material and improving the cutting accuracy.

The first fixing part 480 and the second fixing part 490 first press and position the two ends of the flexible material in the cutting area, and then the second cylinder 460 drives the movable cutter 470 to press down and cooperate with the fixed cutter 430 to cut the flexible material. After the cutting is completed, the cutting assembly 130 is lifted to its original position, and the conveyor belt 340 rotates so that the positioning assembly 350 on the side close to the discharge roller 220 is transported to the other side of the cutting assembly 130, and then the user releases the cut material head and cuts the required length next time. The positioning assembly 350 after use is blocked and guided to a parallel state with the conveyor belt 340 by the recovery part 710, and the cycle is repeated in sequence.

[0063] Through the above, efficient and accurate cutting of flexible materials is achieved, which not only improves the cutting efficiency, but also ensures the cutting quality, provides great convenience for users, and at the same time, makes the entire cutting process more automated.
