Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of trademark printing, especially relates to a trademark machine automatic feeding deviation rectifying device. BACKGROUND

[0002] In the field of trademark printing production, the material feeding link is a basic and key step. During the feeding process, the accuracy of material conveying is related to the yield. During traditional feeding, the material often deviates, and even if there is only a slight deviation, the key content such as patterns and characters will deviate from the standard position after continuous conveying into the printing link. Therefore, in order to meet the growing market demand, a device capable of automatic feeding and real-time deviation rectification is needed to realize high-speed and efficient trademark printing production. However, the existing trademark machine automatic feeding deviation rectification mechanism faces many challenges in actual application. For example, the patent with publication number CN214878927U discloses a roll material automatic feeding deviation rectification device, which uses ball screw transmission for the deviation rectification assembly and the driving assembly. The surface wear of the screw rod increases the transmission gap, and dust, debris, etc. are extremely easy to enter the ball circulation channel to hinder the normal rolling of the balls, causing poor transmission, thereby reducing the overall response speed and deviation rectification accuracy. Moreover, during operation, dust is easy to adhere or accumulate on the surface of the material and the sensor, which will change the refraction, reflection, etc. of light, thereby causing misjudgment and affecting the deviation rectification accuracy. SUMMARY

[0003] (I) Technical problems solved

[0004] In view of the limitations of existing automatic feeding deviation rectification devices, the utility model aims to provide a trademark machine automatic feeding deviation rectification device, which uses an ion wind curtain generator to generate an ion wind curtain, which is concentrated and uniformly blown to the material through a wind concentrating and guiding cover and guiding vanes, effectively removing dust and other impurities on the surface of the material, reducing the adhesion or accumulation of dust on the surface of the material, and avoiding misjudgment of the sensor due to changes in the refraction and reflection characteristics of light caused by dust. The "V"-shaped air flow collecting groove can effectively collect the air flow containing dust, which is introduced into a cyclone dust collector through a pipeline for further separation and collection of dust, preventing the spread of dust in the device and reducing the impact of dust on the sensor and other components.

Subsequently, material enters detection area from ion wind curtain dust removal area, photoelectric sensor detects the position of material in real time by emitting light, when photoelectric sensor detects that material deviates, signal is transmitted to control system, control system controls the drive motor connected with two deviation rectifying rollers to work according to the signal transmitted by photoelectric sensor, deviation rectifying roller is rotated by drive motor, rubber protrusion on the surface of deviation rectifying roller generates certain friction force with material, lateral force is exerted on material, so that material returns to correct conveying position, thereby deviation rectification is realized, that is, if material deviates to the left is detected, right deviation rectifying roller is driven to rotate quickly by drive motor, so that material deviates slightly to the right and finally returns to correct conveying position, otherwise, left deviation rectifying roller is driven to rotate quickly, so that material deviates slightly to the left and finally returns to correct conveying position. Fan symmetrically arranged on the two sides of photoelectric sensor is also driven by control system, which can further blow dust and other impurities that may be attached to the surface of material or sensor, ensure the accuracy of photoelectric sensor detection, avoid misjudgment caused by dust and other impurities, and influence rectification accuracy. The specific connection of drive motor and deviation rectifying roller, the specific connection of control system and drive motor, fan and the like all adopt existing technology, so detailed description is not made.

[0007] Preferably, the middle two sides of the ion wind curtain dust removal area are symmetrically provided with two first conveying rollers, the middle two sides of the detection area are symmetrically provided with two second conveying rollers, and the two deviation correction rollers are arranged between the two second conveying rollers. Each of the first conveying roller, the second conveying roller and the deviation correction roller is connected with a driving motor. The first conveying rollers are symmetrically arranged in the middle of the ion wind curtain dust removal area, so that the material is uniformly conveyed on both sides when passing through the ion wind curtain dust removal area, that is, the two first conveying rollers are arranged at the front end and the rear end of the material conveying direction in the ion wind curtain dust removal area, respectively, to ensure stable conveying of the material. Similarly, the second conveying rollers symmetrically arranged in the detection area are also arranged at the front end and the rear end of the material conveying direction in the detection area, respectively, to ensure stable conveying of the material. The rubber roller set, the first conveying roller, the second conveying roller and the deviation correction roller are arranged on the same horizontal line, and each rubber roller, the first conveying roller, the second conveying roller and the deviation correction roller are connected with a specific driving motor, that is, each rubber roller, the conveying roller and the deviation correction roller can be independently controlled by driving the driving motor through the control system. The specific connection mode adopts conventional technology, and therefore will not be described in detail.

[0008] Preferably, the surface of each of the first conveying roller, the second conveying roller and the deviation correction roller is uniformly provided with a plurality of rubber protrusions. The surface of each of the first conveying roller, the second conveying roller and the deviation correction roller is provided with rubber protrusions. In the material conveying process, the rubber protrusions directly contact the material, so that the material and the roller form multi-point and large-area contact, generate stronger friction, and make the material steadily advance with the rotation of the roller, avoiding the risk of slipping. Especially after the material enters the detection area, once the photoelectric sensor captures the signal of the position deviation of the material and transmits it to the control system, the control system immediately drives the corresponding driving motor of the deviation correction roller to respond. At this time, the deviation correction roller cleverly applies a lateral force to the material by means of the friction between the rubber protrusions and the material. Due to the increase of the contact area and the gripping force of the rubber protrusions, the lateral force can accurately and effectively push the material back to the correct conveying path, realize high-precision deviation correction, and ensure that the material always advances along the preset track.

[0009] Preferably, each rubber roller group is composed of four evenly arranged rubber rollers, and the surface of each rubber roller is evenly provided with a plurality of rubber protrusions. The material is conveyed between the upper and lower rubber roller groups, and the rubber rollers roll the conveyed material while smoothing it. The four evenly arranged rubber rollers form a stable and uniform support structure, and when the material enters the smoothing area, it is subjected to uniform and moderate pressure under the combined action of the four rubber rollers, which means that the force acting on each part of the material at the same time is nearly the same, thereby effectively avoiding wrinkles, stretching deformation and other problems caused by uneven stress, and ensuring the flatness and smoothness of the material. The rubber protrusions on each rubber roller, on the one hand, greatly enhance the friction between the roller and the material. When the driving motor drives the rubber roller group to rotate, the rubber protrusions pull the material forward with strong friction, making the material fully straightened before entering the ion wind curtain dust removal area, avoiding adverse conditions such as edge curling and curling, and laying a solid foundation for accurate dust removal and subsequent deviation correction.

[0010] On the other hand, for materials with relatively smooth surfaces, the rubber protrusions can increase the actual contact area with the material by moderate compression, thereby ensuring sufficient friction; and for materials with slightly rough surfaces or even containing fine particles, the rubber protrusions can also achieve close and stable contact through elasticity, ensuring that the smoothing effect is not compromised.

[0011] Preferably, the ion wind curtain generator is provided with an air outlet on the side facing the material, and a air volume adjusting valve is arranged at the air outlet. The ion wind curtain generator is fixed in the middle of the top inner wall of the ion wind curtain dust removal area, i.e. at the top end of the material, and the air outlet of the ion wind curtain generator faces the material. The wind curtain generated by the ion wind curtain generator can be directly delivered to the surface of the material, and the wind curtain can cover the entire surface of the material, i.e. the air outlet of the ion wind curtain generator cannot be too narrow, and the air outlet is arranged along the transportation direction of the material. The air volume adjusting valve can adjust the amount of wind curtain generated by the generator, thereby adjusting the air volume blowing to the surface of the material. The air volume adjusting valve is connected with the control system, and the size of the air volume adjusting valve can be controlled by the control system, thereby adjusting the air volume. The specific setting and connection method adopts conventional technology, and therefore will not be described in detail.

[0012] Preferably, the wind gathering dome is gradually unfolded downward, and the inner wall of the wind gathering dome is uniformly provided with diagonal lines. When the ion wind curtain generator generates a wind curtain and blows it outward, the wind curtain is initially in a relatively concentrated airflow beam state, the shape of the gradually unfolded downward wind gathering dome is similar to a "horn" that expands outward to guide the wind curtain airflow to gradually spread out, the wind curtain flows downward along the inner wall of the wind gathering dome, and the coverage area continuously increases. It should be noted that, in order to ensure that the entire material surface can be blown by the wind curtain, the wind gathering dome can cover the entire material surface, that is, the largest outer circle of the wind gathering dome is attached to the inner wall of the ion wind curtain dust removal area, so that the wind gathering dome can completely cover the material.

[0013] Preferably, the cyclone dust collector is fixed to the outer wall surface of the ion wind curtain dust removal area. The cyclone dust collector is externally hung on one side of the outer wall of the ion wind curtain dust removal area, and the cyclone dust collector is fixedly connected with the airflow collecting groove through a pipeline. The airflow collecting groove is arranged in a "V" shape, and the airflow carrying dust is guided to the bottom end to be deposited into the pipeline, and finally transported to the cyclone dust collector through the pipeline, so as to avoid further diffusion of dust in the device, pollution of other components or reattachment to the material surface.

[0014] (Three) beneficial effects

[0015] (1) The rubber roller group is composed of four rubber rollers arranged uniformly, and the surface is covered with rubber protrusions.

[0016] (2) The ion wind curtain dust removal area is provided with an ion wind curtain generator facing the material and along the transportation direction, and cooperates with the air volume adjusting valve to accurately adjust the air volume according to the material characteristics, so that the wind curtain fully covers the surface of the material, strongly removes dust and impurities, ensures that the wind curtain acts uniformly and stably on the material, and improves the dust removal effect.

Detailed Implementation

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1 - Appendix Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1: As Figure 1 As shown, the first specific embodiment of this utility model provides an automatic feeding and correction device for a trademark machine, including a frame 1. A smoothing zone 2, an ion curtain dust removal zone 3, and a detection zone 4 are sequentially fixed on the frame 1. The smoothing zone 2 includes symmetrically arranged rubber roller sets 21. The ion curtain dust removal zone 3 includes an ion curtain generator 31 fixed to the inner wall of the top of the dust removal zone. An air-gathering guide hood 32 is fixedly connected to the side of the ion curtain generator 31 facing the material. Several guide vanes 33 are arranged on the inner wall of the air-gathering guide hood 32. The guide vanes 33 are distributed and staggered along the inner wall of the air-gathering guide hood 32. The guide vanes 33 are arc-shaped. An airflow collection trough 34 is fixedly connected to the bottom of the ion curtain dust removal zone 3. The airflow collection trough 34 is arranged in a "V" shape. A cyclone dust collector 35 is fixedly connected to its bottom through a pipe. The detection zone 4 includes two symmetrically arranged correction rollers 41 in the middle of the detection zone 4. A photoelectric sensor 42 is fixedly connected to the middle of the inner wall of the top of the detection zone 4. Fans 43 are symmetrically arranged on both sides of the photoelectric sensor 42. The upper and lower symmetrical rubber roller groups 21 of the smoothing zone 1 are driven by the drive motor 5. By using the rubber protrusions on the surface of the rubber rollers 210 to contact the material, just the right pressure and friction can be applied to effectively smooth the material, eliminate defects such as wrinkles and curled edges, and allow the material to smoothly transition to the subsequent process in an ideal flat state, laying a solid foundation for accurate correction.

[0026] The ion wind curtain generator 31 is arranged in the middle of the inner wall of the top end of the ion wind curtain dust removal area 3, accurately faces the material, and has an air outlet arranged along the material conveying direction, which is matched with the air volume adjusting valve 311 to flexibly adjust the wind curtain strength for different materials and thicknesses, ensure complete dust removal, and make the wind curtain cover the material in all directions to strongly clean the dust and impurities.

[0027] The polytropic fairing 32 is in a downward unfolding shape and has staggered arc-shaped guide vanes 33 on the inner wall, so that the wind curtain airflow is more evenly distributed. The guide vanes disturb the airflow, make the dust particles more easily be wrapped and carried, and enhance the dust capturing capacity; at the same time, the guide vanes guide the wind curtain to stably blow to the material, ensure the stable and reliable dust removal effect, and greatly improve the accuracy and comprehensiveness of dust removal.

[0028] The "V"-shaped airflow collection groove 34 efficiently collects the dust-containing airflow, rapidly guides the dust-containing airflow into the externally-hung cyclone dust collector through the pipeline, and the cyclone dust collector 35 uses centrifugal force to throw the dust to the cylinder wall and collect it, and the purified air is discharged, which effectively prevents the dust from circulating and polluting in the device and always maintains a clean environment for material processing.

[0029] The ion wind curtain dust removal area 3 is symmetrically provided with two first conveying rollers 36 between the middle of the two sides, the detection area 4 is symmetrically provided with two second conveying rollers 44 between the middle of the two sides, and two deviation correcting rollers 41 are arranged between the two second conveying rollers 44. Each of the first conveying roller 36, the second conveying roller 44 and the deviation correcting roller 41 is connected with a driving motor 5. The two first conveying rollers 36 and the two second conveying rollers 44 enable the material to be stably conveyed between the two rollers, enable the wind curtain to comprehensively and uniformly act on the surface of the material, effectively remove the dust and impurities, improve the dust removal effect, ensure the uniform conveying of the material in the dust removal area, avoid the material from being stagnant or shaken, ensure the continuity and stability of the dust removal process, and improve the production efficiency. The deviation correcting roller 41 can monitor and correct the conveying position deviation of the material in real time, ensure that the material is always on the correct conveying path in the detection area 4, improve the detection accuracy, and reduce the detection errors and misjudgments caused by the deviation of the material. In addition, the deviation correcting roller 41 can timely adjust the position of the material to avoid the material from colliding with, rubbing against or other actions with the detection equipment or other components due to the deviation, reduce the defects such as scratches and deformation on the surface of the material, and improve the yield of the product.

[0030] The surface of each of the first conveying roller 36, the second conveying roller 44 and the deviation correcting roller 41 is uniformly provided with a plurality of rubber protrusions. The rubber protrusions can increase the friction between the roller surface and the material, prevent the material from slipping during the conveying process, ensure the stable conveying of the material in the ion wind curtain dust removal area 3 and the detection area 4, and be beneficial to improving the accuracy of dust removal and detection. In addition, for the deviation correcting roller 41, greater friction can make the deviation correction action more effective, more accurately control the position of the material, timely correct the deviation of the material, and ensure that the material is always conveyed along the correct path.

[0031] In addition, for some soft or easily deformed materials, the rubber protrusions can disperse the pressure, so that the materials are subjected to more uniform pressure, reducing the risk of deformation of the materials due to excessive local stress. At the same time, during the conveying process, the rubber protrusions can absorb and buffer the vibration and impact force between the rollers and the materials and between the rollers, reducing the noise generated during the operation of the equipment and improving the working environment.

[0032] The rubber roller set 21 is composed of four rubber rollers 210 arranged uniformly, and the surface of each rubber roller 210 is uniformly provided with a plurality of rubber protrusions. The four rubber rollers 210 are arranged uniformly to disperse the weight of the materials, so that the overall load-bearing capacity of the rubber roller set 21 is improved, and the equipment can be adapted to convey heavier and larger materials, thereby expanding the application range of the equipment. At the same time, the uniform distribution of the four rubber rollers 210 forms a stable support structure, which can better maintain the balance of the materials during the conveying process, reduce the shaking and deviation of the materials during the conveying process, and improve the stability of the conveying, especially for long-size or high-barycenter materials.

[0033] The ion wind curtain generator 31 is provided with an air outlet 310 facing the material measuring side, and an air volume adjusting valve 311 is arranged at the air outlet 310. The air volume adjusting valve 311 can accurately adjust the air volume of the ion wind curtain according to the characteristics of the materials and the actual dust removal demand. For materials with more dust on the surface or strong dust adhesion, the air volume can be increased to enhance the blowing capacity of the wind curtain on the dust, ensuring complete removal of the dust; for materials with a sensitive surface or easy to be damaged, the air volume can be reduced to ensure the dust removal effect while avoiding damage to the materials caused by excessive pressure of the wind curtain.

[0034] The wind collecting and guiding cover 32 is gradually unfolded downward, and the inner wall of the wind collecting and guiding cover 32 is uniformly provided with diagonal stripes. From the propagation path of the wind curtain, when the ion wind curtain generator 31 generates the wind curtain and blows it outwards, the wind curtain is initially in a relatively concentrated airflow beam state. The shape of the wind collecting and guiding cover 32 gradually unfolding downward can skillfully guide the wind curtain airflow to gradually diffuse. As the wind curtain flows downward along the inner wall of the wind collecting and guiding cover 32, its coverage area continuously increases, ensuring that the wind curtain can accurately and uniformly cover the surface of the materials of different widths below. This shape design avoids the problems of energy concentration and uneven coverage caused by direct blowing of the wind curtain, allowing the wind curtain to act on the materials in a softer and more comprehensive manner, improving the uniformity and effectiveness of dust removal.

[0035] The oblique stripes on the inner wall of the wind deflector 32 can effectively disrupt the regular flow of the air current, causing more tiny eddies and turbulence when the air current flows through the stripes, greatly enhancing the wind curtain's ability to capture dust particles. On the other hand, the oblique stripes also serve to strengthen the wind curtain's guiding nature. Since the stripes have a certain angle of inclination, they can provide an additional tangential force for the wind curtain air current, guiding the wind curtain to blow more accurately along the predetermined direction towards the material surface. This is particularly important during high-speed transportation of the material. Even if the material is subject to some shaking or speed variation, the wind curtain can still be guided by the oblique stripes to act stably and accurately on the material, ensuring that the dust removal work is not disturbed and always maintains efficient operation.

[0036] The cyclone dust collector is fixed to the outer wall surface of the ion wind curtain dust removal area. The ion wind curtain mainly blows dust away from the material surface through ionized air flow, while the cyclone dust collector separates dust from gas using centrifugal force. The combination of the two can form a more comprehensive and efficient dust removal system. After the ion wind curtain raises the dust, the cyclone dust collector can quickly collect and separate the dust-containing gas, further reducing the dust content in the air and improving the overall dust removal effect, ensuring the cleanliness of the material surface. For some small particles or heavy dust particles that the ion wind curtain cannot completely remove, the cyclone dust collector can take advantage of its strengths to deeply purify these dusts. It can capture the remaining impurities in the dust blown out by the ion wind curtain, effectively reducing the residue of dust in the ion wind curtain dust removal area, making the dust removal effect more thorough.

[0037] Working principle: After the material enters the device, it first passes through the flattening area 2. The control system controls the driving motor to drive the upper and lower symmetrically arranged rubber roller group 21 to flatten the material. After passing through the four evenly arranged rubber rollers 210, the material is effectively flattened under the extrusion and friction of the upper and lower rubber roller group 21. The wrinkles or bends on the surface of the material are eliminated. The flattened material enters the ion wind curtain dust removal area 3 and contacts the first conveying roller 36 on both sides, completely entering the ion wind curtain dust removal area 3. Then, the control system controls the ion wind curtain generator 31 to start, blowing out the ion wind curtain through the air outlet 310. The air volume regulating valve 311 at the air outlet 310 can adjust the air volume of the wind curtain according to the material condition and dust removal demand. The blown wind curtain is gathered and directed to the material surface by the wind gathering guide 32. The diagonal lines on the inner wall help guide the airflow to act more evenly on the material surface. At the same time, the arc-shaped guide vanes 33 arranged alternately on the inner wall of the wind gathering guide 32 further make the airflow uniformly distributed and change the airflow direction, making the wind curtain more comprehensive and effective in blowing off the dust and other impurities on the material surface. The dust and other impurities blown off the material surface move downward with the airflow into the "V"-shaped airflow collection groove 34 at the bottom of the ion wind curtain dust removal area 3 and deposit at the bottom of the "V"-shaped airflow collection groove 34. These dust-containing airflows are then transported through the pipeline to the cyclone dust collector 35 fixed on the outer wall surface of the ion wind curtain dust removal area 3. The cyclone dust collector 35 separates the dust from the airflow using centrifugal force, achieving efficient collection and treatment of dust. The purified airflow can be discharged or subjected to subsequent treatment. The control system drives the driving motor connected to the first conveying roller 36 and the second conveying roller 44 to rotate, causing the material to be further conveyed to the detection area 4. At this time, the two deviation correction rollers 41 located in the middle of the detection area 4 work cooperatively with the two second conveying rollers 44 under the action of the driving motor connected to the deviation correction rollers. The photoelectric sensor 42 simultaneously detects the position information of the material in real time. When the material deviates is detected, the photoelectric sensor 42 transmits the signal to the control system, which controls the driving motor connected to the deviation correction roller 41 to adjust the speed and direction of the deviation correction roller 41, so that the deviation correction roller 41 applies appropriate force to the material to correct it to the correct position, ensuring that the material is always conveyed along the set path. At the same time, the control system controls the fans 43 symmetrically arranged on both sides of the photoelectric sensor 42 to rotate, which helps to blow off the remaining dust and also helps to maintain air flow in the detection area, reducing the influence of dust accumulation on detection accuracy.
