Description

Technical Field

[0001] This invention relates to the field of slitting equipment technology, specifically to a PLC-controlled die-cutting and slitting equipment. Background Technology

[0002] In the cigarette production process, the cigarette packaging materials need to be cut according to production needs. This step is not only related to the appearance quality of the finished cigarettes, but also to the fact that cigarette packaging materials, such as paper boxes or plastic films, are usually supplied in long rolls on the production line. In order to neatly and tightly package the cigarettes into these materials, the materials first need to be precisely cut according to the preset size 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 existing slitting and cutting equipment, to reduce the occurrence of defective products due to differences in cut width or length, adjustments are made to the slitting section of the equipment. This involves pressing the cigarette packaging paper firmly at the corresponding slitting components to prevent misalignment during the slitting process. However, in practical applications, besides misalignment at the slitting position due to insufficient pressing, the tension of the material during transport also affects the yield rate of the slitting and cutting process. When the material transport is too loose, misalignment and changes in the material's conveying position can easily occur, affecting the overall stability of the material transport. Conversely, when the material transport is too tight, changes in the material's width can easily occur, affecting the width of the cut material and thus the yield rate. Summary of the Invention

[0007] The tension detection mechanism includes a light refraction layer coated on the top end face of the first base, a light source assembly disposed above the first base, and a light sensing assembly that receives the light reflected from the light source assembly.

[0008] The main frame is equipped with a PLC controller for controlling the adjustment mechanism.

[0011] As an improvement to the above solution, the clamping roller group includes a first clamping roller and a second clamping roller, which are arranged sequentially from top to bottom along the height direction of the main frame body, and the roller surfaces of the first clamping roller and the second clamping roller are in contact with each other;

[0012] The second clamping roller group includes a third clamping roller and a fourth clamping roller. The third clamping roller and the fourth clamping roller are arranged sequentially from top to bottom along the height direction of the main frame body, and the roller surfaces of the third clamping roller and the fourth clamping roller are in contact with each other.

[0013] The second clamping roller and the fourth clamping roller are arranged parallel to each other on the same horizontal plane, and their ends on the same side are connected to the adjustment mechanism through a helical gear.

[0014] As an improvement to the above scheme, the other end of the first clamping roller and the second clamping roller on the same side is provided with a meshing spur gear one and a spur gear two, and the other end of the third clamping roller and the fourth clamping roller on the same side is provided with a meshing spur gear three and a spur gear four.

[0015] As an improvement to the above solution, the end of the second clamping roller connected to the adjustment mechanism is provided with a first helical gear, a second helical gear and a third helical gear at equal intervals from the middle to the end.

[0016] The fourth clamping roller is connected to the adjustment mechanism at one end, from the middle to the end, where a fourth spiral gear, a fifth spiral gear, and a sixth spiral gear are provided at equal intervals.

[0017] The first helical gear and the sixth helical gear have the same diameter, the second helical gear and the fifth helical gear have the same diameter, and the third helical gear and the fourth helical gear have the same diameter.

[0018] As an improvement to the above solution, the adjustment mechanism includes a transmission shaft that is alternately arranged with the second clamping roller and the fourth clamping roller, and a seventh helical gear sleeved on the transmission shaft. The seventh helical gear meshes with any one of the following groups along the axial direction of the transmission shaft: the first helical gear and the fourth helical gear, the second helical gear and the fifth helical gear, and the third helical gear and the sixth helical gear.

[0023] The beneficial effects of this invention are as follows: the device has a good PLC control foundation, and through the good cooperation between the control terminal and the PLC controller, the tensioning mechanism in the control device can be kept in a state that can be reasonably controlled. By adding light sensing components and other related structures to the tension detection mechanism, the width change of the material under tension during the transmission process is judged by light refraction, and transmitted to the control terminal for processing in real time. In other words, the whole device solves the problems of correction and real-time control of material tension while reducing the intensity of manual detection operations. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0032] like Figure 1 and Figure 2 As shown, a PLC-controlled die-cutting and slitting equipment includes a frame body 1 and a first base 101 and a second base 102 arranged sequentially along the longitudinal direction of the frame body 1. The first base 101 has a plurality of feeding rollers 2 at the upper station. The end face of the first base 101 is provided with a tensioning mechanism and a tension detection mechanism 5. The end face of the second base 102 is provided with a feeding roller group 6 and a slitting device 7.

[0033] The tensioning mechanism includes a clamping roller group 3 and a clamping roller group 4 arranged at the front and rear ends of the first base 101 along the material conveying direction. The frame body 1 is provided with an adjustment mechanism 8 for adjusting the speed of the tensioning mechanism at the ends of the clamping roller group 3 and the clamping roller group 4.

[0034] like Figure 1 and Figure 5 As shown, the tension detection mechanism 5 includes a light refraction layer 501 coated on the top end face of the first base 101, a light source assembly 502 disposed above the first base 101, and a light sensing assembly 503 that receives the light reflected by the light source assembly 502.

[0035] The frame body 1 is equipped with a PLC controller for controlling the adjustment mechanism 8. The control signal input terminal and control data output terminal of the PLC controller are connected to the control terminal, while the control signal output terminal and control data input terminal 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.

[0036] In the technical solution of the present invention, the control terminal is any one or more of the following: a handheld button controller with screen display, a fixed control box, a personal computer, and a personal handheld smart terminal. The control terminal is matched and connected to the PLC controller through wired or wireless control. The PLC controller receives control data and outputs control signals.

[0037] Furthermore, the PLC controller structure involved in this 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 requirements of this invention, such as control signal input terminal, control data output terminal, control signal output terminal and control data input terminal, and support the ability to be remotely controlled by the host computer via the control terminal. Generally speaking, most types of PLC controllers can meet this requirement, so their circuit control structure and basic control principle will not be described here.

[0038] 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 roll unwinding and conveying mode. The frame body 1 can be set on both sides of the material width, and the material is conveyed between the two frame bodies 1. Alternatively, the frame body 1 can be set on one side of the material width, and the material is conveyed along either side of the frame body 1.

[0039] Furthermore, the feeding roller 2, clamping roller group 1 3, first base 101, clamping roller group 2 4, and second base 102 are arranged along the material conveying direction. When the frame body 1 is arranged on both sides of the material width, the two ends of the feeding roller 2, clamping roller group 1 3, clamping roller group 2 4, and 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, one end of the feeding roller 2, clamping roller group 1 3, clamping roller group 2 4, and feed roller group 6 on the same side is hinged to the frame body 1. The material passes over the feeding roller 2, clamping roller group 1 3, clamping roller group 2 4, and feed roller group 6 in sequence along the conveying direction.

[0040] like Figure 1 As shown, in the technical solution of the present invention regarding the feeding roller 2, the feeding roller 2 includes a first feeding roller 201 and a second feeding roller 202. The first feeding roller 201 is disposed below the second feeding roller 202, and the horizontal height of the second feeding roller 202 is aligned with the horizontal height of the end face of the first base 101.

[0041] In use, the feeding roller 2 is used to feed the rolled material. The rolled material passes around the first feeding roller 201 and the second feeding roller 202 in sequence. Generally, the horizontal height of the first feeding roller 201 is higher or lower than the horizontal height of the rolled material, which is determined by the horizontal height of the position of the rolled material. In a conventional setting, the first feeding roller 201 and the second feeding roller 202 are parallel to each other, and the horizontal height of the second feeding roller 202 is aligned with the horizontal height of the end face of the first base 101. This allows the rolled material to be conveyed to the fixed end face of the first base 101 in a relatively stable posture after passing around the second feeding roller 202.

[0042] 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 3 and a clamping roller group 4 arranged at the front end and rear end of the first base 101 along the material conveying direction. The clamping roller group 3 and the clamping roller group 4 clamp and convey the material along the material conveying direction. The adjusting mechanism 8 adjusts the rotation speed between the clamping roller group 3 and the clamping roller group 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 conveyed to the subsequent slitting device 7 under appropriate tension.

[0043] Specifically, the end of the feeding roller 2 is not subject to an external drive device for its rotation. The material is fed onto the feeding roller 2 by the traction force of the clamping roller group 3. The end of the feeding roller group 6 is not subject to an external drive device for its rotation. In one embodiment, the feeding roller group 6 and the clamping roller group 4 are connected by a synchronous transmission structure, so that the rotation speed of the feeding roller group 6 is the same as that of the clamping roller group 4. Under the above conditions, the rotation speed relationship between the clamping roller group 3 and the clamping roller group 4 determines the tension of the material surface.

[0044] Specifically, along the dividing line of the clamping roller group 3, the front position direction of the clamping roller group 3 is the first conveying section, and the rear position direction of the clamping roller group 4 is the second conveying section. When the rotation speed of the clamping roller group 3 is the same as that of the clamping roller group 4, the material conveying speed of the first conveying section and the second conveying section is the same.

[0045] When the rotational speed of the clamping roller group 3 is lower than that of the clamping roller group 4, the material conveying speed of the first conveying section is lower than that of the second conveying section. Under the traction of different speeds, the material width of the second conveying section is smaller than that of the first conveying section.

[0046] When the rotational speed of the clamping roller group 3 is greater than that of the clamping roller group 4, the material conveying speed of the first conveying section is greater than that of the second conveying section. Under the traction of different speeds, the material width of the second conveying section gradually widens until it is equal to the material width of the first conveying section.

[0047] In the specific structure of the clamping roller group 3 of the present invention, the clamping roller group 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 arranged sequentially 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.

[0048] 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. The third clamping roller 401 and the fourth clamping roller 402 are arranged sequentially 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.

[0049] The second clamping roller 302 and the fourth clamping roller 402 are arranged parallel to each other on the same horizontal plane, and their ends on the same side are connected to the adjustment mechanism 8 through a helical gear.

[0050] Furthermore, in the above scheme, the other end of the first clamping roller 301 and the second clamping roller 302 on the same side is provided with a meshing spur gear 303 and a spur gear 304, and the other end of the third clamping roller 401 and the fourth clamping roller 402 on the same side is provided with a meshing spur gear 403 and a spur gear 404.

[0051] Furthermore, in the above scheme, 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.

[0052] The fourth clamping roller 402 is connected to the adjustment mechanism 8 at one end, from the middle to the end, a fourth spiral gear 405, a fifth spiral gear 406 and a sixth spiral gear 407 are provided at equal intervals.

[0053] 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.

[0054] As an improvement to the above solution, the adjustment mechanism 8 includes a transmission shaft 801 that is alternately arranged with the second clamping roller 302 and the fourth clamping roller 402, and a seventh helical gear 802 sleeved on the transmission shaft 801. The seventh helical gear 802 meshes with any one of the following groups along the axial direction of the transmission shaft 801: 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.

[0055] The adjustment mechanism 8 further includes a linear drive device and a rotary drive device. The output end of the rotary 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 rotary drive device, the transmission shaft 801, and the seventh helical gear 802 to reciprocate along the axis of the transmission shaft 801.

[0056] The adjustment mechanism 8 of the present invention has three modes for adjusting the rotational speed of the clamping roller group 3 and the clamping roller group 4. In the first adjustment mode, the seventh helical gear 802 meshes with the second helical gear 306 and the fifth helical gear 406, the rotational speed of the second clamping roller 302 and the fourth clamping roller 402 is the same, the material conveying speed of the first conveying section and the second conveying section is the same, and the material width of the first conveying section is the same as the material width of the second conveying section.

[0057] In the second adjustment mode, the seventh helical gear 802 is connected to the first helical gear 305 and the fourth helical gear 405. The diameter of the first helical gear 305 is larger than that of the fourth helical gear 405, so that the rotational speed of the second clamping roller 302 is lower than that of the fourth clamping roller 402. Under the action of the speed difference, a 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 that of the first conveying section.

[0058] In the third adjustment mode, the seventh helical gear 802 is connected to the third helical gear 307 and the sixth helical gear 407. The diameter of the third helical gear 307 is smaller than that of the sixth helical gear 407, so that the rotational speed of the second clamping roller 302 is lower than that of the fourth clamping roller 402. Under the action of the speed difference, the traction force applied by the clamping roller group 2 4 to 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.

[0059] 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 face of the first base 101, a light source assembly 502 disposed above the first base 101, and a light sensing assembly 503 for receiving the light reflected by the light source assembly 502.

[0060] In the tension detection technology of the present invention, the width of the light refraction layer 501 is greater than the width of the material. When the light source assembly 502 emits light that irradiates the light refraction layer 501, the light refracted at the unobstructed positions on both sides of the light refraction layer 501 is received by the light sensing assembly 503 and an image is generated. The width of the material can be obtained from the width of the shaded portion corresponding to the shading in the image. This width is then compared with the ideal cutting width of the material to determine the tension state of the material. When the width of the shading portion is less than the ideal cutting width of the material, the material surface is too tense, and the PLC controller controls the operation of the third adjustment mode to make the width of the shading portion equal to the ideal cutting width of the material. When the width of the shading portion is greater than the ideal cutting width of the material, the material surface is too loose, and the PLC controller controls the operation of the first adjustment mode to make the width of the shading portion equal to the ideal cutting width of the material.

[0061] In the technical solution of the correction device 9 of the present invention, a correction device 9 is provided between the first base 101 and the second base 102. The correction device 9 includes a pair of horizontally arranged correction rollers and a correction drive device arranged above the correction rollers to drive the ends of the correction rollers to swing along the height direction. The structure of the correction device 9 involved in the present invention can actually be set up using existing correction devices 9. The selection of the correction device 9 is to obtain and meet the requirement of the present invention to drive the ends of the correction rollers to swing along the height direction to achieve the purpose of correction. Generally speaking, most types of correction devices 9 can meet this requirement, so their specific structure and basic control principle will not be described here.

[0062] In use, the tension detection component can simultaneously detect whether there is any deviation in the material transmission process. When the light source component 502 emits light and shines on the light refraction layer 501, the light refracted by the unobstructed parts on both sides of the light refraction layer 501 is received by the light sensing component 503 and an image is generated. The width of the material can be obtained by corresponding to the width of the shadowed part in the image. By comparing whether the width of the unobstructed parts on both sides of the light refraction layer 501 in the image is equal, it can be determined whether the material has shifted to one side.

[0063] Furthermore, in the above scheme, the feed roller group 6 includes a first feed roller 601 and a second feed roller 602 disposed at the front end and rear end of the second base 102 along the conveying direction. The roller surfaces of the first feed roller 601 and the second feed roller 602 are both in contact with the top end face of the second base 102, and a transmission belt 603 for synchronous rotation is connected to one end on the same side.

[0064] 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 4. 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 the material is conveyed along the second conveying section, and ensuring that the material is conveyed to the slitting device 7 for slitting with the ideal width size.

[0065] Furthermore, in the above scheme, the cutting device 7 is located in the middle of the top end face of the second base 102, including a fixed bracket 701 spanning the material conveying direction, a linear drive cylinder 702 fixedly mounted on the fixed bracket 701 with its output end pointing vertically downward, and a cutting bracket 703 fixedly mounted on the output end of the linear drive cylinder 702. The cutting bracket 703 is provided with a cutting shaft 704, and a plurality of circular cutter discs 705 are provided at equal intervals along the width direction of the cutting shaft 704.

[0066] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
