Description

Technical Field

[0001] The invention relates to the technical field of slitting processing equipment, and specifically designs a die-cutting and striping equipment based on PLC control. Background Art

[0002] In the cigarette production process, the coils for producing cigarette packaging need to be cut according to production needs. This step is not only related to the appearance quality of the finished cigarettes. Cigarette packaging coils, such as paper boxes or plastic films, are usually supplied in long rolls on the production line. In order to pack cigarettes neatly and tightly into these materials, the coils must first be accurately cut according to preset sizes and specifications. The cutting process is completed by slitting equipment to ensure the accuracy and consistency of each cut, thereby avoiding waste of packaging materials and improving overall production efficiency.

[0003] In most of the existing technologies of slitting and stripping equipment, in order to reduce the production of defective products due to different cutting widths or lengths, people make adjustments to the slitting part of the equipment, and press the cigarette packaging paper at the position of the corresponding slitting component to avoid the packaging paper from shifting during the slitting process. However, in actual applications, in addition to the material shifting at the slitting position due to lack of compression, the tension of the material during the transmission process will also affect the yield of material slitting and stripping. When the material transmission is too loose, it is easy to cause deviation and change the material conveying position, affecting the stability of the overall material transmission. When the material transmission is too tight, it is easy to cause the width of the material to change, which will also affect the width of the material after slitting and affect the yield.

DETAILED DESCRIPTION

[0021] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0022] like Figure 1 and Figure 2 As shown, a die-cutting and slitting device based on PLC control includes a frame body 1 and a first base 101 and a second base 102 arranged in sequence along the longitudinal direction of the frame body 1, a plurality of feeding rollers 2 are arranged at the upper station of the first base 101, a tensioning mechanism and a tensioning detection mechanism 5 are arranged on the end surface of the first base 101, and a feeding roller group 6 and a slitting device 7 are arranged on the end surface of the second base 102; The tensioning mechanism comprises a clamping roller set 1 3 and a clamping roller set 2 4 arranged at the front and rear ends of the first base 101 along the material transmission direction, and the frame body 1 is connected to the ends corresponding to the clamping roller set 1 3 and the clamping roller set 2 4 and is provided with an adjustment mechanism 8 for adjusting the rotation speed of the tensioning mechanism; like Figure 1 and Figure 5 As shown, the tension detection mechanism 5 includes a light refraction layer 501 coated on the top end surface of the first base 101, a light source component 502 disposed above the first base 101, and a light sensing component 503 receiving light reflected by the light source component 502; The frame body 1 is provided with a PLC controller for controlling the adjustment mechanism 8. The control signal input end and the control data output end of the PLC controller are connected to the control terminal, and the control signal output end and the control data input end of the PLC controller are connected to the light source component 502, the light sensing component 503 and the adjustment mechanism 8, and form a control loop with each other.

[0023] In the technical solution of the present invention, the control terminal is any one or more of a handheld key controller with a screen display, a fixed control box, a personal computer, and a personal handheld smart terminal. The control terminal is matched and connected with a PLC controller through wired control or wireless control, and the PLC controller receives control data and outputs control signals; Furthermore, the PLC controller structure involved in the present invention can actually be set up using the control module in the existing PLC control system. The PLC controller is selected to be able to obtain and meet the control signal input terminal, control data output terminal, control signal output terminal and control data input terminal ports required by the present invention, and support the ability of accessing the control terminal to be remotely controlled by the host computer. Generally speaking, most types of PLC controllers can meet this point, so the circuit control structure and basic control principle will not be described here. like Figure 1 As shown, in the technical solution of the present invention regarding the frame body 1, the material is conveyed along the length direction of the frame body 1, the feeding roller 2 and the frame body 1 are arranged with reference to the existing coil unwinding conveying mode, the frame body 1 can be arranged on both sides of the material width, and the material is conveyed between the frame bodies 1 on both sides, and the frame body 1 can also be arranged on one side of the material width, and the material is conveyed along any side of the frame body 1; Further, the feeding roller 2, the clamping roller group 1 3, the first base 101, the clamping roller group 2 4, and the second base 102 are arranged along the conveying direction of the material. When the frame body 1 is arranged on both sides of the material width, the two ends of the feeding roller 2, the clamping roller group 1 3, the clamping roller group 2 4 and the feed roller group 6 are respectively hinged to the frame body 1 on both sides. When the frame body 1 is arranged on one side of the material, the ends of the feeding roller 2, the clamping roller group 1 3, the clamping roller group 2 4 and the feed roller group 6 on the same side are hinged to the frame body 1, and the material bypasses the feeding roller 2, the clamping roller group 1 3, the clamping roller group 2 4 and the feed roller group 6 in sequence along the conveying direction; like Figure 1 As shown, in the technical solution of the present invention regarding the loading roller 2, the loading roller 2 includes a first loading roller 201 and a second loading roller 202, the first loading roller 201 is arranged below the second loading roller 202, and the horizontal height of the second loading roller 202 is aligned with the horizontal height of the end surface of the first base 101; When in use, the loading roller 2 is used to discharge the rolled material, and the rolled material passes around the first loading roller 201 and the second loading roller 202 in sequence. Generally speaking, whether the horizontal height of the first loading roller 201 is higher or lower than the horizontal height of the first loading roller 201 is determined by the horizontal height of the position of the rolled material. In a conventional setting, the first loading roller 201 and the second loading roller 202 are parallel, and the horizontal height of the second loading roller 202 is aligned with the horizontal height of the end face of the first base 101, so that the rolled material can be wound around the second loading roller 202 and transported to the fixed end face of the first base 101 in a relatively stable posture.

[0024] like Figures 1 to 5 As shown, in the technical solution of the tensioning mechanism of the present invention, the tensioning mechanism includes a clamping roller group 1 3 and a clamping roller group 2 4 arranged at the front end and the rear end of the first base 101 along the material transmission direction, the clamping roller group 1 3 and the clamping roller group 2 4 clamp the material along the material conveying direction for conveying, and the adjustment mechanism 8 adjusts the rotation speed between the clamping roller group 1 3 and the clamping roller group 2 4 to apply a tensile force to the length direction of the material, thereby changing the width of the material, so that the material is at a suitable tension and is transmitted to the subsequent slitting device 7; Specifically, the end of the feeding roller 2 is not applied with an external driving device for driving its self-rotation, and the material is fed on the feeding roller 2 by the traction force of the clamping roller group 3, and the end of the feeding roller group 6 is not applied with an external driving device for driving its self-rotation. In one embodiment, the feeding roller group 6 is connected to the clamping roller group 2 4 by a synchronous transmission structure, so that the rotation speed of the feeding roller group 6 is consistent with the rotation speed of the clamping roller group 2 4. Under the above premise, the rotation speed relationship between the clamping roller group 3 and the clamping roller group 2 4 determines the tension of the material surface; Specifically, along the clamping roller group 1 3 as a dividing line, the front station direction of the clamping roller group 1 3 is the first conveying section, and the rear station direction of the clamping roller group 2 4 is the second conveying section. When the rotation speed of the clamping roller group 1 3 is the same as the rotation speed of the clamping roller group 2 4, the material conveying speed of the first conveying section is the same as that of the second conveying section. When the rotation speed of the clamping roller group 1 3 is lower than the rotation speed of the clamping roller group 2 4, the material conveying speed of the first conveying section is lower than the material conveying speed of the second conveying section, and under the traction of different speeds, the material width of the second conveying section is smaller than the material width of the first conveying section; When the rotation speed of the clamping roller set 1 3 is greater than the rotation speed of the clamping roller set 2 4, the material conveying speed of the first conveying section is greater than the material conveying speed of the second conveying section. Under the traction of different speeds, the material width of the second conveying section gradually widens to be equal to the material width of the first conveying section. In the specific structure of the clamping roller set 3 of the present invention, the clamping roller set 3 includes a first clamping roller 301 and a second clamping roller 302, the first clamping roller 301 and the second clamping roller 302 are sequentially arranged from top to bottom along the height direction of the frame body 1, and the roller surfaces of the first clamping roller 301 and the second clamping roller 302 are in contact with each other; In the specific structure of the clamping roller group 2 4 of the present invention, the clamping roller group 2 4 includes a third clamping roller 401 and a fourth clamping roller 402, and the third clamping roller 401 and the fourth clamping roller 402 are sequentially arranged from top to bottom along the height direction of the frame body 1, and the roller surfaces of the third clamping roller 401 and the fourth clamping roller 402 are in contact with each other; The second clamping roller 302 and the fourth clamping roller 402 are arranged in parallel on the same horizontal plane, and one end on the same side is connected to the adjustment mechanism 8 through a helical gear.

[0025] Furthermore, in the above scheme, the other end on the same side of the first clamping roller 301 and the second clamping roller 302 is provided with a meshing connected spur gear 1 303 and a meshing connected spur gear 2 304, and the other end on the same side of the third clamping roller 401 and the fourth clamping roller 402 is provided with a meshing connected spur gear 3 403 and a meshing connected spur gear 4 404.

[0026] Furthermore, in the above solution, the end of the second clamping roller 302 connected to the adjustment mechanism 8 is provided with a first helical gear 305, a second helical gear 306 and a third helical gear 307 at equal intervals from the middle to the end; The end of the fourth clamping roller 402 connected to the adjustment mechanism 8 is provided with a fourth helical gear 405, a fifth helical gear 406 and a sixth helical gear 407 at equal intervals from the middle to the end; The first helical gear 305 has the same diameter as the sixth helical gear 407 , the second helical gear 306 has the same diameter as the fifth helical gear 406 , and the third helical gear 307 has the same diameter as the fourth helical gear 405 ; As an improvement of the above solution, the adjustment mechanism 8 includes a transmission shaft 801 staggered with the second clamping roller 302 and the fourth clamping roller 402, and a seventh helical gear 802 sleeved on the transmission shaft 801, and the seventh helical gear 802 is meshed with any one of the first helical gear 305 and the fourth helical gear 405, the second helical gear 306 and the fifth helical gear 406, and the third helical gear 307 and the sixth helical gear 407 along the axial direction of the transmission shaft 801; The adjusting mechanism 8 also includes a linear drive device and a rotation drive device. The output end of the rotation drive device is fixedly connected to the end of the transmission shaft 801. The output shaft of the linear drive device is aligned with the axis of the transmission shaft 801, driving the rotation drive device, the transmission shaft 801 and the seventh helical gear 802 to reciprocate along the axis direction of the transmission shaft 801.

[0027] The adjustment mechanism 8 of the present invention has three modes for adjusting the rotation speed of the clamping roller group 1 3 and the clamping roller group 2 4. In the first adjustment mode, the seventh helical gear 802 is meshed with the second helical gear 306 and the fifth helical gear 406, the rotation speeds of the second clamping roller 302 and the fourth clamping roller 402 are the same, the material conveying speeds of the first conveying section and the second conveying section are the same, and the material width of the first conveying section is the same as the material width of the second conveying section; In the second adjustment mode, the seventh helical gear 802 is connected to the first helical gear 305 and the fourth helical gear 405, and the diameter of the first helical gear 305 is larger than the diameter of the fourth helical gear 405, so that the rotation speed of the second clamping roller 302 is lower than the rotation speed of the fourth clamping roller 402. Under the action of the speed difference, traction force is generated between the clamping roller group 2 4 and the clamping roller group 1 3, so that the material width of the second conveying section is smaller than the material width of the first conveying section; In the third adjustment mode, the seventh helical gear 802 is connected to the third helical gear 307 and the sixth helical gear 407, and the diameter of the third helical gear 307 is smaller than the diameter of the sixth helical gear 407, so that the rotation speed of the second clamping roller 302 is lower than the rotation speed of the fourth clamping roller 402. Under the effect of the rotation speed difference, the traction force applied by the clamping roller group 2 4 on the clamping roller group 1 3 is reduced until the material width of the second conveying section gradually widens to be equal to the material width of the first conveying section. In the technical solution of the tension detection mechanism 5 of the present invention, the tension detection mechanism 5 includes a light refraction layer 501 coated on the top end surface of the first base 101, a light source component 502 arranged above the first base 101, and a light sensing component 503 receiving light reflected by the light source component 502; In the tension detection technical solution of the present invention, the width dimension of the light refraction layer 501 is larger than the width dimension of the material, and the light source component 502 emits light to illuminate the light refraction layer 501. The refracted light at the positions on both sides of the light refraction layer 501 that are not blocked by the material is received by the light sensing component 503, and an image is generated. The width dimension of the material can be obtained from the width dimension of the blocked shadow part in the corresponding image, and then compared with the ideal cutting width dimension of the comparison material to obtain the tension state of the material. When the width dimension of the blocked part is smaller than the ideal cutting width dimension of the material, the surface of the material is too tight, and the PLC controller controls the operation of the third adjustment mode to make the width dimension of the blocked part equal to the ideal cutting width dimension of the material; when the width dimension of the blocked part is larger than the ideal cutting width dimension of the material, the surface of the material is too loose, and the PLC controller controls the operation of the first adjustment mode to make the width dimension of the blocked part equal to the ideal cutting width dimension of the material; In the technical solution of the deflection correcting device 9 of the present invention, a deflection correcting device 9 is provided between the first base 101 and the second base 102, and the deflection correcting device 9 includes deflection correcting rollers arranged in pairs horizontally and a deflection correcting driving device arranged above the deflection correcting rollers to drive the ends of the deflection correcting rollers to swing in the height direction; the deflection correcting device 9 structure involved in the present invention can actually be arranged using the existing deflection correcting device 9, and the selection of the deflection correcting device 9 is to be able to obtain and meet the requirements of the present invention to drive the ends of the deflection correcting rollers to swing in the height direction to achieve the purpose of deflection correction. Generally speaking, most types of deflection correcting devices 9 can meet this point, so their specific structure and basic control principle will not be described here; When in use, the tension detection component can synchronously detect whether there is a deviation in the material transmission process. The light source component 502 emits light to illuminate the light refraction layer 501. The refracted light at the positions on both sides of the light refraction layer 501 that are not blocked by the material is received by the light sensing component 503 and an image is generated. The width size of the material can be obtained from the width size of the blocked shadow part in the corresponding image. By comparing whether the width sizes of the unblocked parts on both sides of the light refraction layer 501 in the image are equal, it can be determined whether the material is deviated to one side. Further, in the above scheme, the feed roller group 6 includes a first feed roller 601 and a second feed roller 602 arranged at the front end and the rear end of the second base 102 along the conveying direction, and the roller surfaces of the first feed roller 601 and the second feed roller 602 are both in contact with the top end surface of the second base 102, and a transmission belt 603 for synchronous rotation is connected to one end of the same side; like Figure 6 As shown, in one embodiment of the present invention, a synchronously rotating transmission belt 603 is also connected between the first feed roller 601 and the clamping roller group 2 4, and the transmission belt 603 synchronously drives the fourth clamping roller 402, the first feed roller 601 and the second feed roller 602 to rotate synchronously, ensuring that the width of the material will not change due to the speed difference between the rollers when it is conveyed along the second conveying section, and ensuring that the material is conveyed to the slitting device 7 with an ideal width size for slitting.

[0028] Furthermore, in the above scheme, the slitting device 7 is arranged in the middle of the top end face of the second base 102, including a fixed bracket 701 across the material conveying direction, a linear drive cylinder 702 fixedly arranged on the fixed bracket 701 with the output end vertically downward, and a cutting bracket 703 fixedly arranged at the output end of the linear drive cylinder 702, and a cutting shaft 704 is provided on the cutting bracket 703, and a plurality of circular knife discs 705 are evenly spaced along the width direction of the cutting shaft 704.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
