Description

Technical Field

[0001] The invention relates to a cutting device, and in particular to a film slitting device and method. Background Art

[0002] With the continuous improvement of production technology, the width of the composite film produced is getting larger and larger. In the existing film processing equipment, the width of each device that can be fed is limited, resulting in the composite film with too large width cannot be directly fed into the film processing equipment. Therefore, it is necessary to configure additional unwinding, slitting, and winding equipment to achieve the slitting of the composite film produced before it can be transferred to the required film processing equipment. The entire production line occupies a large space volume, the equipment cost is high, and the entire operation process is time-consuming and cumbersome. Therefore, there is an urgent need for a device that can more conveniently slit the film to improve the overall production efficiency. Summary of the invention

[0003] The object of the present invention is to provide a film slitting device and method to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A film slitting device comprises: a slitting mechanism having a slitting knife for slitting film materials; a deviation corrector for deviating one slit film material from another slit film material; and a winding mechanism having a winding roller for winding up a plurality of the film materials respectively.

[0006] This technical solution has at least the following beneficial effects: after the external film material is processed and formed through processes such as lamination, it is led to the slitting knife in the slitting mechanism, and the slitting knife cuts the film material into two parts. At this time, the two cut film materials are close to each other. In order to facilitate direct winding, one of the film materials is led through the deflection corrector, and the deflection corrector makes the film material offset away from the other film material, so that the distance between the two film materials can be increased. At this time, the two film materials are led to the winding roller, and the winding roller directly winds up the two film materials. The obtained film roll can be directly transferred to the required film processing equipment for use. Therefore, the present invention directly cuts the processed film material and uses the deflection corrector to increase the distance between the two film materials, so as to directly wind the cut film material into two rolls, thereby reducing the equipment investment cost, and the operation is convenient and fast, which greatly improves the overall benefit.

[0007] As a further improvement of the above technical solution, the present invention also includes a first bow roller, which is located between the slitting mechanism and the deflection corrector. The two films separated by the slitting knife pass through the first bow roller, and the two films are respectively against the positions on both sides of the center of the first bow roller. The two films cut out by the slitting mechanism pass through the first bow roller before being conveyed to the deflection corrector. At this time, the two films are respectively against the positions on both sides of the center of the first bow roller. The arc-shaped bending characteristics of the first bow roller can be used to separate the two films in the direction away from the center of the first bow roller. In this way, the films can be pre-separated to form a certain distance before being conveyed to the deflection corrector, thereby improving the separation effect of the two films.

[0008] As a further improvement of the above technical solution, the present invention further includes a first guide roller, which is located between the first bow roller and the deflection corrector, and the two films passing through the first bow roller bypass the first guide roller. After passing through the first bow roller, the two films pass through the first guide roller, and the first guide roller flattens the two films, and then one of the films is guided to the deflection corrector and the other film is guided to the winding roller, so that the flatness of the film during transportation can be ensured, and the quality of slitting and winding of the film can be improved.

[0009] As a further improvement of the above technical solution, the present invention also includes a second guide roller and a third guide roller. One film material cut by the slitting knife bypasses the deflection corrector and is sent to the third guide roller. Another film material cut by the slitting knife bypasses the second guide roller and the third guide roller and is sent to the winding roller. One film material cut by the slitting knife is deflected by the deflection corrector and is guided to the third guide roller. The third guide roller is used to flatten and transition the film material. Another film material cut by the slitting knife bypasses the second guide roller, adjusts the guiding direction, and then is guided to the third guide roller and sent to the winding roller together with the deflection corrected film material. In this way, the two cut film materials can be guided and separated and then merged and transported together, and the flatness of the film material before winding is improved.

[0010] As a further improvement of the above technical solution, the present invention also includes a second bow roller, which is located between the third guide roller and the winding mechanism, and the two films passing through the third guide roller are respectively against the positions on both sides of the center of the second bow roller. After being separated by the deviation corrector, the two films are guided from the third guide roller to the second bow roller, so that the two films are respectively against the positions on both sides of the center of the second bow roller. By utilizing the bending characteristics of the second bow roller, the two films can be further separated in the direction away from the center of the second bow roller, so that the spacing can be further increased after the film is sent out of the deviation corrector, ensuring the separation effect of the two films.

[0011] As a further improvement of the above technical solution, the present invention also includes a tensioning assembly, which includes a base, a swing arm, a tensioning roller and a linear drive member. The middle part of the swing arm and the fixed end of the linear drive member are respectively rotatably connected to the base, the tensioning roller is rotatably connected to one end of the swing arm, and the movable end of the linear drive member is rotatably connected to the other end of the swing arm. The film material before bypassing the deviation corrector and the film material before bypassing the second guide roller pass through the tensioning roller respectively. The two films pass through the tensioning roller before being sent to the deviation corrector for cutting. The linear drive member can drive the swing arm to rotate, so that the tensioning roller is close to or away from the second guide roller, thereby providing sufficient tensioning force to the film material, thereby ensuring the effect of separating the deviation of the film material.

[0012] As a further improvement of the above technical solution, the slitting mechanism includes a first pressing roller and a second pressing roller, a film passing gap is provided between the first pressing roller and the second pressing roller, and the slitting knife is directly opposite to the film passing gap. When the processed and formed film material is guided to the slitting mechanism, the film material passes through the film passing gap formed between the first pressing roller and the second pressing roller, and the first pressing roller and the second pressing roller press the film material to be straight, and when the film material passes through the slitting knife, the film material can be separated, thereby realizing the slitting of the film material.

[0013] As a further improvement of the above technical solution, the slitting knife can be movable and positioned along the length direction of the first pressing roller. The position of the slitting knife can be adjusted according to the required width of the film material, so that the film material can be rolled into two rolls with different outer diameters, thereby improving the overall flexibility and convenience of use.

[0014] As a further improvement of the above technical solution, the winding mechanism includes a motor, the motor is connected to the winding roller, and at least two winding drums are detachably connected to the winding roller. The motor provides winding power to the winding roller, which can drive the winding roller to rotate, thereby realizing the winding of the film material, and the winding roller is connected to the winding drum, and different film materials can be wound onto different winding drums respectively. After the winding is completed, the winding drum can be disassembled and replaced from the winding roller. The overall structure is simple and easy to use.

[0015] A film slitting method, using the above-mentioned film slitting device, comprising:

[0016] Get the required width value of the membrane material;

[0017] Cutting the film material according to the width value to obtain two cut film materials;

[0018] Leading one of the slit films to pass through the deflection corrector so that the slit film after passing through the deflection corrector deviates from the other slit film;

[0019] The two slit films are rolled up respectively.

[0020] This technical solution has at least the following beneficial effects: when slitting the film material, the position of the slitting knife is adjusted according to the required width value of the film material, and then the film material is guided through the slitting knife to slitting the film material to obtain two slit film materials. At this time, one of the slit film materials is guided through the deflection corrector, and the deflection corrector causes the slit film material to deviate away from the other slit film material, thereby increasing the spacing between the two slit film materials, and the two film materials are guided to the winding roller, which directly winds up the two film materials. The obtained film roll can be directly transferred to the required film processing equipment for use. Therefore, the present invention can directly slit the processed film material and then wind it into two rolls, thereby reducing the equipment investment cost, and the operation is convenient and fast, which greatly improves the overall benefit.

[0029] Reference Figure 1 A film slitting device includes a slitting mechanism 100, a deviation corrector 200 and a winding mechanism, wherein the slitting mechanism 100 has a slitting knife 110, the slitting knife 110 is used to slit the film material; the deviation corrector 200 is used to deviate one slit film material from another slit film material, the deviation corrector 200 includes a wheel frame, an intermediate roller and a side roller, the intermediate roller and the side roller are both rotatably connected to the wheel frame, side rollers are respectively arranged on both sides of the intermediate roller, and the two side rollers are inclined upwardly extending away from the intermediate roller, and the film material The film can pass between the roller group formed by the two side rollers and the middle roller, and the offset distance of the film can be adjusted by adjusting the inclination angle of the two side rollers. When the two film materials are separated from each other, the deviation corrector 200 can only act on one film material to drive it to deviate from the other film material, or the deviation corrector 200 can act on two film materials. At this time, the deviation corrector 200 has two roller groups for the film materials to pass through respectively; the winding mechanism has a winding roller 310, and the winding roller 310 is used to wind up multiple film materials separately.

[0030] As can be seen from the above, after the external film material is processed and formed through processes such as lamination, it is led to the slitting knife 110 in the slitting mechanism 100, and the slitting knife 110 cuts the film material into two parts. At this time, the two cut film materials are close to each other. In order to facilitate direct winding, one of the film materials is led through the corrector 200, and the corrector 200 makes the film material offset away from the other film material, so that the distance between the two film materials can be increased. At this time, the two film materials are led to the winding roller 310, and the winding roller 310 directly winds up the two film materials. The obtained film roll can be directly transferred to the required film processing equipment for use. Therefore, the present invention directly cuts the processed film material and uses the corrector 200 to increase the distance between the two film materials, so as to directly wind the cut film material into two rolls, thereby reducing the equipment investment cost, and the operation is convenient and fast, which greatly improves the overall benefit.

[0031] After the film material is cut by the slitting knife 110, the two cut film materials are still close to each other. In order to improve the separation effect of the film materials, a method of gradually separating the film materials is adopted. Specifically, the present invention also includes a first bow roller 410. Of course, the first bow roller 410 is rotatably installed on a fixed structure. For example, the first bow roller 410 is installed on a frame through a bearing. The first bow roller 410 is located between the slitting mechanism 100 and the deviation corrector 200. The two film materials separated by the slitting knife 110 pass through the first bow roller 410, and the two film materials are respectively against the positions on both sides of the center of the first bow roller 410. The two film materials cut out by the slitting mechanism 100 first pass through the first bow roller 410 before being conveyed to the deflection corrector 200. At this time, the two film materials are respectively against the positions of the first bow roller 410 on both sides of the center. By utilizing the arc-shaped bending characteristics of the first bow roller 410, the two film materials can be separated in the direction away from the center of the first bow roller 410. In this way, the two film materials can be pre-separated to form a certain distance before being conveyed to the deflection corrector 200, thereby improving the separation effect of the two film materials.

[0032] The present invention also includes a first guide roller 420. Of course, the first guide roller 420 is rotatably mounted on a fixed structural member. For example, the first guide roller 420 is mounted on a frame through a bearing. The first guide roller 420 is located between the first bow roller 410 and the deflection corrector 200. The two films passing through the first bow roller 410 bypass the first guide roller 420. After passing through the first bow roller 410, the two films pass through the first guide roller 420 again. The first guide roller 420 flattens the two films, and then guides one of the films to the deflection corrector 200 and the other to the winding roller 310. In this way, the flatness of the film during transportation can be ensured, and the quality of slitting and winding of the film can be improved. In practical applications, there can be multiple first guide rollers 420. At this time, the two films passing through the first bow roller 410 bypass multiple first guide rollers 420 in sequence to achieve the guiding of the film and improve the flexibility of overall installation and use.

[0033] The present invention also includes a second guide roller 430 and a third guide roller 440. Naturally, the second guide roller 430 and the third guide roller 440 are rotatably installed on a fixed structure. For example, the second guide roller 430 and the third guide roller 440 are respectively installed on the frame through bearings. A film material cut by the slitting knife 110 bypasses the deviation corrector 200 and is sent to the third guide roller 440. Another film material cut by the slitting knife 110 bypasses the second guide roller 430 and the third guide roller 440 and is sent to the winding roller 310. One film material cut out by the slitting knife 110 is deflected by the deflection corrector 200 and then guided to the third guide roller 440, and the third guide roller 440 is used to flatten and transition the film material. The other film material cut out by the slitting knife 110 bypasses the second guide roller 430, adjusts the guiding direction, and then is guided to the third guide roller 440, and is sent to the winding roller 310 together with the deflected film material. In this way, the two cut film materials can be guided and separated and then reunited for transportation, and the flatness of the film material before winding is improved.

[0034] The present invention also includes a second bow roller 450. Of course, the second bow roller 450 is rotatably mounted on a fixed structure. For example, the second bow roller 450 is mounted on a frame through a bearing. The second bow roller 450 is located between the third guide roller 440 and the winding mechanism. The two films passing through the third guide roller 440 are respectively against the positions on both sides of the center of the second bow roller 450. After being separated by the deflection corrector 200, the two films are guided from the third guide roller 440 to the second bow roller 450, so that the two films are respectively against the positions on both sides of the center of the second bow roller 450. By utilizing the bending characteristics of the second bow roller 450, the two films can be further separated in the direction away from the center of the second bow roller 450. In this way, the distance can be further increased after the films are sent out of the deflection corrector 200, thereby ensuring the separation effect of the two films.

[0035] In order to flatten the two films passing through the second bow roller 450, a fourth guide roller may be provided between the second bow roller 450 and the winding roller 310, and the two films passing through the second bow roller 450 bypass the fourth guide roller. After passing through the second bow roller 450, the two films pass through the fourth guide roller, which flattens the two films, and then guides the two films to the winding roller 310, so that the films can be made flatter and the slitting and winding quality of the films can be further improved.

[0036] In order to ensure the tensioning force before the film material is offset, the present invention also includes a tensioning assembly, which includes a base, a swing arm 510, a tensioning roller 520 and a linear drive 530. The base can be fixed on a frame or a part of the frame. The middle part of the swing arm 510 and the fixed end of the linear drive 530 are respectively rotatably connected to the base, the tensioning roller 520 is rotatably connected to one end of the swing arm 510, and the movable end of the linear drive 530 is rotatably connected to the other end of the swing arm 510. The film material before bypassing the deviation corrector 200 and the film material before bypassing the second guide roller 430 first pass through the tensioning roller 520. In actual applications, the linear drive 530 is mainly used to provide a driving force for reciprocating swinging in a linear direction. There are various structural forms. For example, the linear drive 530 can adopt a cylinder, an electric screw or a hydraulic cylinder. The two films pass through the tensioning roller 520 before being sent to the deviation corrector 200 for cutting. The linear drive member 530 can drive the swing arm 510 to rotate, so that the tensioning roller 520 approaches or moves away from the second guide roller 430, thereby providing sufficient tensioning force for the film, thereby ensuring the effect of separating the deviated film.

[0037] As a specific structural embodiment of the slitting mechanism 100, Figure 2 As shown, the slitting mechanism 100 includes a first pressing roller 120 and a second pressing roller 130, a film passing gap is provided between the first pressing roller 120 and the second pressing roller 130, and the slitting knife 110 is directly opposite to the film passing gap. When the processed and formed film material is guided to the slitting mechanism 100, the film material passes through the film passing gap formed between the first pressing roller 120 and the second pressing roller 130, and the first pressing roller 120 and the second pressing roller 130 press the film material tightly and straighten it. When the film material passes through the slitting knife 110, the film material can be separated, and the slitting of the film material is realized.

[0038] In practical applications, according to the needs of different processing equipment, a longer film material can be divided into two parts of different widths. At this time, the position of the slitting knife 110 needs to be adjusted according to the position of the film material slitting. Specifically, the slitting knife 110 can be moved and positioned along the length direction of the first pressing roller 120. According to the required width of the film material slitting, the position of the slitting knife 110 can be adjusted, so that the film material can be rolled into two rolls with different outer diameters, thereby improving the overall flexibility and convenience of use. There are many structural methods for movably adjusting and positioning the slitting knife 110. For example, there is a fixed frame in the slitting mechanism 100, and a slide seat is slidably connected to the fixed frame. The slitting knife 110 is connected to the slide seat, and the slide seat can reciprocate along the length direction of the first pressure roller 120 to adjust the position. A locking screw is connected to the slide seat. When it is necessary to position the slitting knife 110, the locking screw is locked and fixed by pressing the end of the locking screw against the fixed frame; or an adjusting screw rod is connected to the fixed frame, and the slitting knife 110 is connected to the adjusting screw rod. The slitting knife 110 can be movably adjusted and positioned along the length direction of the first pressure roller 120 by adjusting the screw rod.

[0039] The winding mechanism has a driving force that can drive the winding roller 310 to rotate, and multiple film materials can be wound on the same winding roller 310. There are various structural forms. In this embodiment, the winding mechanism includes a motor, and the motor is connected to the winding roller 310. At least two winding drums are detachably connected to the winding roller 310. For example, there are two winding rollers 310. At this time, the two winding drums can be inserted into the winding roller 310 from both ends of the winding roller 310, or the two winding drums are inserted from one end of the winding roller 310. The motor provides the winding roller 310 with the power of winding, and can drive the winding roller 310 to rotate, so as to realize the winding of the film material. The winding roller 310 is connected with a winding drum, and different film materials can be wound on different winding drums respectively. After the winding is completed, the winding drum can be disassembled and replaced from the winding roller 310. The overall structure is simple and easy to use.

[0040] A film slitting method, using the above-mentioned film slitting device, includes but is not limited to the following steps:

[0041] Step S100, obtaining the required width value of the film material.

[0042] Step S200, the film material is cut according to the width value to obtain two cut film materials. The position of the cutting knife 110 can be adjusted to adjust the width of the cut film material.

[0043] Step S300, one of the slit films is guided through the deflection corrector 200, so that the slit film after passing through the deflection corrector 200 deviates from the other slit film. The deflection corrector 200 adjusts the position of one of the slit films to deviate from the other slit film.

[0044] Step S400, respectively rolling up the two slit films.

[0045] By using the above-mentioned film slitting method, when the film material is slitting, the position of the slitting knife 110 is adjusted according to the required width value of the film material, and then the film material is guided through the slitting knife 110 to slitting the film material to obtain two slitting film materials. At this time, one of the slitting film materials is guided through the corrector 200, and the corrector 200 causes the slitting film material to deviate from the other slitting film material, so that the distance between the two slitting film materials can be increased, and the two film materials are guided to the winding roller 310, and the winding roller 310 directly winds up the two film materials. The obtained film material roll can be directly transferred to the required film processing equipment for use. Therefore, the present invention can directly slitting the processed film material, and then wind it into two rolls, thereby reducing the equipment investment cost, and the operation is convenient and fast, which greatly improves the overall efficiency.
