Description
Technical Field
[0001] The utility model relates to the field of cutting machines, in particular to a double-beam multi-layer cutting machine. Background Art
[0002] When processing stacked raw materials such as fabrics and leather materials, taking fabrics as an example, multiple layers of fabrics need to be stacked together, and then a cutting machine is used to cut the multi-layer stacked structure, so as to improve the processing rate of the stacked raw materials.
[0003] The cutting machine includes a negative pressure device, a cutting bed body, and a cutting knife. The stacked raw materials to be cut are breathable materials, and an isolation film is covered above the outermost layer of the stacked raw materials. The isolation film covers the breathable holes of the stacked raw materials. When the negative pressure device in the cutting bed body is started, a closed space is formed between the isolation film and the edge of the stacked raw materials for the negative pressure device to form a negative pressure space state, so as to adsorb and fix the multi-layer stacked raw materials on the surface of the cutting bed body, prevent the situation that the multi-layer stacked raw materials slide and displace each other, and also prevent the situation that the stacked raw materials are displaced due to the downward pressure of the cutting knife.
[0004] In order to flatten the fabric for the cutting tool of the cutting machine to cut, a cutting bed body with a large support surface area needs to be set for placing the fabric. However, a large-area cutting bed body can only process the next piece of fabric after processing a complete piece of fabric, resulting in a slow processing rate. And due to site problems in some factories, only one cutting machine can be set, and the overall product is greatly affected by the processing rate of the cutting machine. Therefore, it is necessary to improve the cutting efficiency of the cutting machine to improve the production efficiency of the overall product. Summary of the Utility Model
[0005] In order to improve the overall cutting speed of the cutting machine, the utility model provides a double-beam multi-layer cutting machine.
[0006] The double-beam multi-layer cutting machine provided by the utility model adopts the following technical scheme:
[0007] A double-beam multi-layer cutting machine, characterized in that it includes
[0008] A cutting bed body;
[0009] A cutting knife assembly, slidably connected to the cutting bed body, and at least two groups of the cutting knife assemblies are provided;
[0010] A secondary film laminating device, which is used for winding the isolation film, and the isolation film is used for laminating a second layer of film on the first layer of film of the cut stacked raw materials, and the secondary film laminating device operates simultaneously with the cutting knife assembly;
[0011] A negative pressure device, arranged in the cutting bed body, and a ventilation part is opened on the upper surface of the cutting bed body.
[0012] Place the stacked multi-layer structure on the cutting bed body, and control the two cutting knife assemblies to slide along the length direction of the cutting bed body, so that the area of the raw material stack cut by the two cutting knife assemblies is half of the upper surface area of the raw material stack, thereby shortening the cutting time of the raw material stack on the cutting bed body, and then improving the overall processing speed of the raw material stack.
[0013] On the upper surface of the raw material stack cut by the cutting knife assembly, use the secondary film laminating device to perform secondary film lamination on the upper surface of the raw material stack cut by the cutting knife assembly. Although a layer of isolation film has been covered on the upper surface of the multi-layer raw material stack placed on the cutting bed body, when the cutting knife assembly cuts the multi-layer raw material stack, the isolation film has been synchronously cut out with through holes, resulting in "air leakage", which greatly weakens the adsorption force of the cut part by the negative pressure device. When the multi-layer raw material stack is adsorbed by the negative pressure device, the air in the space between adjacent raw material stacks can be squeezed out. When there is air leakage in the multi-layer raw material stack, the multi-layer raw material stack will bulge as a whole, resulting in easy dislocation and relative displacement between layers. Therefore, it is necessary to use the secondary film laminating device to perform secondary film lamination on the multi-layer raw material stack, reduce the possibility of relative sliding between layers, ensure the stable fixation of the multi-layer structure, and thus improve the stability of the cutting and processing operation of the cutting machine with double beam setting.
[0014] Preferably, slide rails are provided on both sides of the cutting bed body, the cutting knife assemblies are slidably connected to the slide rails, and the two cutting knife assemblies share a set of slide rails.
[0015] The setting that the two cutting knife assemblies share a set of slide rails improves the utilization rate of the slide rails of the cutting bed body, and at the same time, when the cutting machine increases the cutting knife assemblies, the overall structure of the cutting machine will not become more complex due to the increased cutting knife assemblies.
[0016] Preferably, there are two sets of the secondary film laminating devices. The two ends of the isolation film connected to the first set of secondary film laminating devices are respectively connected to the cutting bed body and the cutting knife assembly near the feeding end of the cutting bed body;
[0017] The two ends of the isolation film connected to the second set of secondary film laminating devices are respectively connected to the sides of the two cutting knife assemblies close to each other.
[0018] When operating the cutting knife assemblies to cut, move the first set of cutting knife assemblies to the feeding end of the cutting bed body, move the second set of cutting knife assemblies to the middle of the cutting bed body, and then start the two sets of cutting knife assemblies to cut. Set the second set of secondary film laminating devices between the two sets of cutting knife assemblies, and use the existing device to connect the isolation film of the second set of secondary film laminating devices, which can simplify the overall device.
[0019] Preferably, the secondary film laminating device includes a winding assembly and a film pressing assembly. The winding assembly fixes one end of the isolation film. The film pressing assembly is arranged on the cutting table body. The film pressing assembly includes a pressing roller. The pressing roller moves in a direction close to or away from the upper surface of the cutting table body. The pressing roller is rotatably connected to the cutting knife assembly. The isolation film is wound around the outer periphery of the pressing roller.
[0020] Fix one end of the isolation film to the winding assembly. When the cutting knife assembly cuts the raw material stack and then moves along the length direction of the cutting table body, the film pressing assembly arranged on the cutting knife assembly moves synchronously with the cutting knife assembly. The isolation film wound on the pressing roller is released. Before the cutting knife assembly moves, adjust the pressing roller so that the pressing roller presses on the isolation film tightened between the winding assembly and the pressing roller, so that the isolation film is pressed on the upper surface of the multi-layer structure on the cutting table body. The negative pressure device can suck the isolation film covered by the secondary film laminating device. When the cutting knife assembly moves, the isolation film is pulled out, and the isolation film is pressed by the pressing roller and covers the multi-layer structure cut by the cutting knife assembly, so as to achieve the purpose of secondary film lamination at the cutting place of the multi-layer structure.
[0021] Preferably, the winding assembly of one group of the secondary film laminating devices includes two support rods and a connecting rod. The support rods are used to support the connecting rod. The support rods are arranged at one end of the cutting table body;
[0022] The winding assembly of the other group of the secondary film laminating devices includes a film pulling roller. The film pulling roller and the pressing roller are respectively arranged on one side where two cutting knife assemblies are close to each other. The film pulling roller is movably connected to the cutting knife assembly close to the connecting rod. The pressing roller is movably connected to the cutting knife assembly away from the connecting rod; when the cutting knife assembly operates, the pressing roller and the film pulling roller respectively press on both ends of the secondary film between the two cutting knife assemblies, so that both ends of the isolation film are attached to the raw material stack. The rotating directions of the film pulling roller and the pressing roller are the same.
[0023] The winding assembly for fixing the end of the isolation film of the first group of secondary film laminating devices is arranged at one end of the cutting table body. When the cutting knife assembly close to the connecting rod moves, the pressing roller on the cutting knife assembly presses down and at the same time makes the pressing roller rotate, so that the isolation film on the pressing roller is released. The pressing roller presses the isolation film on the surface of the multi-layer structure, and cooperates with the negative pressure device to realize the secondary film lamination of the first section of the multi-layer structure.
[0024] For the second group of secondary film laminating devices, use the previous group of cutting knife assemblies as part of the winding assembly, set the film pulling roller for pulling the film on the previous group of cutting knife assemblies, and then release the isolation film by rotating the pressing roller. The film pulling roller moves in the same direction and winds the isolation film, so that the isolation film covered on the second section of the multi-layer structure avoids the movement of the first group of cutting knife assemblies, and avoids the situation that the secondary film lamination of the second section of the multi-layer structure hinders the cutting of the multi-layer structure by the first group of cutting knife assemblies.
[0025] The synchronous movement of the film pulling roller on the first set of cutting knife assemblies and the pressure roller on the second set of cutting knife assemblies can simultaneously straighten the separator film between the film pulling roller and the pressure roller, preventing the situation where air filling spaces occur at the folds due to the folds of the separator film, which further makes it difficult to tightly suck the multi-layer structure.
[0026] Preferably, both the pressure roller and the film pulling roller are provided with automatic winding components.
[0027] The automatic winding component can be a drive motor controlled by electricity or an ordinary mechanical structure such as a torsion spring. Since the separator film pressed on the multi-layer structure is affected by the adsorption of the negative pressure device, the pressure roller is difficult to rotate due to the resistance of the negative pressure, but instead unwinds the separator film under the driving movement of the cutting knife assembly. However, since the separator film in the secondary film covering is not cut by the cutting knife assembly, the separator film in the secondary film covering can be recycled. When the cutting knife assembly moves back to the initial processing station, the pressure roller automatically winds up the separator film pressed on the cutting bed body for subsequent recycling.
[0028] Preferably, the cutting knife assembly includes a sliding rail and a knife body. The sliding rail is perpendicular to the sliding rail. The knife body is slidably connected to the sliding rail. The knife body is movably connected to the side of the sliding rail close to the support rod. The knife body is arranged on the side of the pressure roller away from the winding assembly.
[0029] The knife body is arranged on the side of the pressure roller away from the winding assembly, which is beneficial to preventing the situation where the knife body cuts the secondary film covering. The knife body moves along the length direction of the cutting bed body on the sliding rail or moves along the width direction of the cutting bed body along the sliding rail to realize the overall cutting of the raw material stack.
[0030] Preferably, the film pressing assembly includes an extension arm. One end of the extension arm is rotatably connected to the sliding rail. The pressure roller is rotatably connected to the end of the extension arm away from the sliding rail.
[0031] The setting of the extension arm assists the pressure roller to be away from the knife body. When it is necessary to press down the separator film, rotate the extension arm so that the end of the extension arm away from the sliding rail abuts against the separator film on the multi-layer structure.
[0032] Preferably, an anti-collision device is provided between the two sets of cutting knife assemblies. The anti-collision device includes an infrared emitter and a receiver. The emitter and the receiver are respectively arranged on the sides of the two knife bodies close to each other.
[0033] When the receiver receives the infrared ray emitted by the emitter and thus senses that the distance between the two is too small, it transmits a signal to the control system of the cutting machine to separate the two sets of cutting knife assemblies that are too close to prevent the two sets of cutting knife assemblies from colliding, which is beneficial to protecting the cutting knife assemblies.
[0034] Preferably, the support rod is provided with a plurality of support points, and the plurality of support points are evenly distributed along the length direction of the support rod.
[0035] When the thicknesses of the multi-layer structures are different, the connecting rod can be fixed at a plurality of support points at different heights to adjust the height of the connecting rod, which is beneficial to improving the overall adaptability range of the device.
[0036] In summary, the utility model includes the following beneficial technical effects:
[0037] Place the stacked multi-layer structures on the cutting bed body, and control the two cutting knife assemblies to slide along the length direction of the cutting bed body, so that the areas of the raw material laminations cut by the two cutting knife assemblies are both one-half of the upper surface area of the raw material lamination, thereby shortening the cutting time of the raw material lamination on the cutting bed body, and further improving the overall processing speed of the raw material lamination.
[0038] On the upper surface of the raw material lamination cut by the cutting knife assembly, use the secondary film laminating device to perform secondary film lamination on the upper surface of the raw material lamination cut by the cutting knife assembly. Although a layer of isolation film has been covered on the upper surface of the multi-layer raw material laminations placed on the cutting bed body, when the cutting knife assembly cuts the multi-layer raw material laminations, through holes have been synchronously cut out in the isolation film, resulting in an "air leakage" situation. As a result, the adsorption force of the negative pressure device on the cut part is greatly weakened. When the multi-layer raw material laminations are adsorbed by the negative pressure device, the air in the space between adjacent raw material laminations can be squeezed out. When there is an air leakage situation in the multi-layer raw material laminations, the multi-layer raw material laminations will show an overall expansion situation, resulting in easy dislocation and relative displacement between layers. Therefore, it is necessary to use the secondary film laminating device to perform secondary film lamination on the multi-layer raw material laminations, reduce the possibility of relative sliding between layers, ensure the stable fixation of the multi-layer structure, and thus improve the stability of the cutting and processing operation of the cutting machine with a double-beam setting.

[0045] The following is a further detailed description of the present utility model in conjunction with the attached Figure 1-2 This utility model will be further described in detail.
[0046] An embodiment of the present utility model discloses a double-beam multi-layer cutting machine.
[0047] Referring to Figure 1 , a double-beam multi-layer cutting machine, characterized in that it includes
[0048] A cutting bed body 1;
[0049] A cutting knife assembly 2, which is slidably connected to the cutting bed body 1, and at least two groups of cutting knife assemblies 2 are provided;
[0050] A secondary film laminating device, which is used for winding the isolation film 4, and the isolation film 4 is used for laminating a second layer of film on the first layer of film of the cut raw material stack, and the secondary film laminating device operates simultaneously with the cutting knife assembly 2;
[0051] A negative pressure device, which is arranged in the cutting bed body 1, and a ventilation part is opened on the upper surface of the cutting bed body 1.
[0052] Place the stacked multi-layer structure on the cutting bed body 1, and control the two cutting knife assemblies 2 to slide along the length direction of the cutting bed body 1, so that the area of the raw material stack cut by the two cutting knife assemblies 2 is one-half of the upper surface area of the raw material stack, thereby shortening the cutting time of the raw material stack on the cutting bed body 1, and then improving the overall processing speed of the raw material stack.
[0053] On the upper surface of the raw material stack cut by the cutting knife assembly 2, use a secondary film laminating device to cover the upper surface of the raw material stack cut by the cutting knife assembly 2 with a second isolation film 4. Although the upper surface of the multi-layer raw material stack placed on the cutting bed body 1 is already covered with a first isolation film, when the cutting knife assembly 2 cuts the multi-layer raw material stack, it has simultaneously cut through the first isolation film to form through holes, resulting in "air leakage". As a result, the adsorption force of the cut part by the negative pressure device is greatly weakened. When the multi-layer raw material stack is adsorbed by the negative pressure device, it can squeeze out the air in the space between adjacent raw material stacks. When there is an air leakage situation in the multi-layer raw material stack, the multi-layer raw material stack will show an overall expansion situation, resulting in easy dislocation and relative displacement between layers. Therefore, it is necessary to use a secondary film laminating device to perform secondary film lamination on the multi-layer raw material stack, reduce the possibility of relative sliding between layers, ensure the stable fixation of the multi-layer structure, and thus improve the stability of the cutting and processing operation of the cutting machine with a double-beam setting.
[0054] Refer to Figure 1 And Figure 2 In this embodiment, slide rails are provided on both sides of the cutting bed body 1, and the cutting knife assemblies 2 are slidably connected to the slide rails. The two cutting knife assemblies 2 share a set of slide rails.
[0055] The setting that the two cutting knife assemblies 2 share a set of slide rails improves the utilization rate of the slide rails of the cutting bed body 1. At the same time, when the cutting machine increases the cutting knife assembly 2, the overall structure of the cutting machine will not become more complex due to the added cutting knife assembly 2.
[0056] There are two sets of the secondary film laminating devices. The two ends of the isolation film connected to the first set of secondary film laminating devices are respectively connected to the cutting bed body and the cutting knife assembly near the feeding end of the cutting bed body.
[0057] The two ends of the isolation film connected to the second set of secondary film laminating devices are respectively connected to the sides where the two cutting knife assemblies are close to each other.
[0058] When operating the cutting knife assembly for cutting, move the first set of cutting knife assemblies to the feeding end of the cutting bed body, move the second set of cutting knife assemblies to the middle of the cutting bed body, and then start the two sets of cutting knife assemblies for cutting. By setting the second set of secondary film laminating devices between the two sets of cutting knife assemblies and using the existing device to connect the isolation film of the second set of secondary film laminating devices, the overall device can be simplified.
[0059] Reference Figure 1 and Figure 2 , in this embodiment, one of the cutting knife assemblies 2 starts moving from one end of the cutting bed body 1, and the other cutting knife assembly 2 starts moving from the raw material stack. The moving directions of the two cutting knife assemblies 2 are the same.
[0060] One of the cutting knife assemblies 2 starts moving from the middle of the raw material stack, and the other cutting knife assembly 2 starts moving from the end of the raw material stack, which is beneficial to reducing the middle part where an avoidance structure needs to be set to assist in cutting the interference of the two cutting knife assemblies 2 in the movement, making it difficult to cut the raw material stack, and at the same time can avoid the situation where the two cutting knife assemblies 2 collide during the cutting process.
[0061] Reference Figure 1 and Figure 2 , in this embodiment, the secondary film laminating device includes a winding assembly and a film pressing assembly. The winding assembly fixes one end of the isolation film 4, and the film pressing assembly is arranged on the cutting bed body 1. The film pressing assembly includes a pressing roller 5, and the pressing roller 5 moves in a direction close to or away from the upper surface of the cutting bed body 1, so that the pressing roller 5 can press on the surface of the secondary film lamination or away from the raw material stack. The pressing roller 5 is rotatably connected to the cutting knife assembly 2, and the isolation film 4 is wound around the outer periphery of the pressing roller 5.
[0062] Fix one end of the isolation film 4 to the winding assembly. After the cutting knife assembly 2 cuts the raw material stack, the cutting knife assembly 2 continues to move along the length direction of the cutting bed body 1. At this time, the film pressing assembly arranged on the cutting knife assembly 2 moves synchronously with the cutting knife assembly 2, and the isolation film 4 wound on the pressing roller 5 is released. Before the cutting knife assembly 2 moves, adjust the pressing roller 5 so that the pressing roller 5 presses on the isolation film 4 tightened between the winding assembly and the pressing roller 5, so that the isolation film 4 is pressed on the upper surface of the multi-layer structure on the cutting bed body 1, and the negative pressure device can suck the isolation film 4 covered by the secondary film laminating device. When the cutting knife assembly 2 moves, the isolation film 4 is pulled out, and the isolation film 4 is pressed by the pressing roller 5 and covers the multi-layer structure cut by the cutting knife assembly 2, so as to achieve the purpose of secondary film lamination at the cutting place of the multi-layer structure.
[0063] Reference Figure 1 and Figure 2 , in this embodiment, there are two groups of secondary film laminating devices. The winding assembly of one group of secondary film laminating devices includes two support rods 31 and a connecting rod 32. The support rods 31 are used to support the connecting rod 32, and the support rods 31 are arranged at one end of the cutting bed body 1;
[0064] The winding assembly of another set of secondary film laminating devices includes a film pulling roller 33. The film pulling roller 33 and the pressure roller 5 are respectively arranged on one side close to each other of the two cutting knife assemblies 2. The film pulling roller 33 is movably connected to the cutting knife assembly 2 close to the connecting rod 32, and the pressure roller 5 is movably connected to the cutting knife assembly 2 far from the connecting rod 32. When the cutting knife assembly 2 operates, the pressure roller 5 and the film pulling roller 33 respectively press on both ends of the secondary film laminate between the two cutting knife assemblies 2. The rotating directions of the film pulling roller 33 and the pressure roller 5 are the same, so that both ends of the isolation film 4 are attached to the raw material laminate.
[0065] The winding assembly of the first set of secondary film laminating devices for fixing the end of the isolation film 4 is arranged at one end of the cutting bed body 1. When the cutting knife assembly 2 close to the connecting rod 32 moves, the pressure roller 5 on the cutting knife assembly 2 presses down, and at the same time makes the pressure roller 5 rotate, so that the isolation film 4 on the pressure roller 5 is released. The pressure roller 5 presses the isolation film 4 on the surface of the multi-layer structure, and cooperates with the negative pressure device to realize the secondary film lamination of the first section of the multi-layer structure.
[0066] For the second set of secondary film laminating devices, using the previous set of cutting knife assemblies 2 as part of the winding assembly, the film pulling roller 33 for pulling the film is arranged on the previous set of cutting knife assemblies 2, and then the isolation film 4 is released by the rotating pressure roller 5. The film pulling roller 33 moves in the same direction and winds up the isolation film 4, so that the isolation film 4 secondarily covered on the second section of the multi-layer structure avoids the movement of the first set of cutting knife assemblies 2, and prevents the secondary film lamination of the second section of the multi-layer structure from hindering the cutting of the multi-layer structure by the first set of cutting knife assemblies 2.
[0067] In this embodiment, the knife body 22 is selected as a pneumatic knife, which is relatively more stable.
[0068] In this embodiment, a driving cylinder 34 is arranged at the end of the film pulling roller 33. The film pulling roller 33 moves in the vertical direction under the drive of the driving cylinder 34.
[0069] Refer to Figure 1 and Figure 2 , in this embodiment, the connecting rod 32, the pressure roller 5 and the film pulling roller 33 are all provided with automatic winding parts.
[0070] The automatic winding part can be a driving motor controlled by electricity, or an ordinary mechanical structure such as a torsion spring. Since the isolation film 4 pressed on the multi-layer structure is affected by the adsorption of the negative pressure device, the pressure roller 5 is difficult to rotate due to the resistance of the negative pressure, but instead unwinds the isolation film 4 under the driving movement of the cutting knife assembly 2. However, since the isolation film 4 in the secondary film lamination is not cut by the cutting knife assembly 2, the isolation film 4 in the secondary film lamination can be recycled. When the cutting knife assembly 2 moves back to the initial processing station, the pressure roller 5 automatically winds up the isolation film 4 pressed on the cutting bed body 1 for subsequent recycling.
[0071] Refer toFigure 1 and Figure 2 In this embodiment, the cutting knife assembly 2 includes a sliding rail 21 and a knife body 22. The sliding rail 21 is perpendicular to the sliding rail, and the knife body 22 is slidably connected to the sliding rail 21. The knife body 22 is movably connected to one side of the sliding rail 21 close to the support rod 31, and the knife body 22 is arranged on the side of the pressure roller 5 away from the winding assembly.
[0072] The knife body 22 is arranged on the side of the pressure roller 5 away from the winding assembly, which is beneficial to preventing the knife body 22 from cutting the secondary coating film. The knife body 22 moves along the length direction of the cutting table body 1 on the sliding rail or moves along the width direction of the cutting table body 1 along the sliding rail 21 to realize the overall cutting of the raw material stack.
[0073] Refer to Figure 1 and Figure 2 In this embodiment, the film pressing assembly includes an extension arm 51. One end of the extension arm 51 is rotatably connected to the sliding rail 21, and the pressure roller 5 is rotatably connected to the end of the extension arm 51 away from the sliding rail 21.
[0074] The setting of the extension arm 51 assists the pressure roller 5 to be away from the knife body 22. When it is necessary to press down the isolation film 4, the extension arm 51 is rotated so that the end of the extension arm 51 away from the sliding rail 21 abuts against the isolation film 4 on the multi-layer structure.
[0075] In this embodiment, the extension arm 51 is driven to rotate by a motor. In other embodiments, the extension arm 51 can also be driven to rotate by a cylinder.
[0076] Refer to Figure 1 and Figure 2 In this embodiment, an anti-collision device is provided between the two cutting knife assemblies 2. The anti-collision device includes an infrared emitter and a receiver, and the emitter and the receiver are respectively arranged on the sides of the two knife bodies 22 close to each other.
[0077] When the receiver receives the infrared ray emitted by the emitter and thus senses that the distance between the two is too small, a signal is transmitted to the control system to separate the two cutting knife assemblies 2 that are too close to prevent the two cutting knife assemblies 2 from colliding, which is beneficial to protecting the cutting knife assembly 2.
[0078] Refer to Figure 1 and Figure 2 In this embodiment, the support rod 31 is provided with a plurality of support points 35, and the plurality of support points 35 are evenly distributed along the length direction of the support rod 31.
[0079] When the thickness of the multi-layer structure is different, the connecting rod 32 can be fixed at a plurality of support points 35 at different heights to adjust the height of the connecting rod 32, which is beneficial to improving the overall adaptation range of the device.
[0080] The cutting machine body 1 is provided with a conveyor belt, the surface of the conveyor belt is covered with supporting comb strips, the supporting comb strips are deformable, the supporting comb strips are used to support a multi-layer structure, the surface of the conveyor belt is hollowed out with air holes, and a negative pressure machine is arranged inside the conveyor belt.
[0081] When the knife body 22 presses down for cutting, in order to fully cut the multi-layer structure placed in a stacked manner, the knife body 22 needs to penetrate the multi-layer structure. If a traditional conveyor belt is used, the knife body 22 is likely to cut the surface of the conveyor belt. Therefore, the supporting comb strips can protect the conveyor belt.
[0082] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
