Description

Technical Field

[0001] This invention relates to the manufacture of articles made from materials processed in a paper, paperboard, or similar manner; the field of processing technology for materials processed in a paper, paperboard, or similar manner; and particularly to a correction component for a high-speed bag-making machine. Background Technology

[0002] Existing transport packaging bags are prone to deviation, causing the edges and corners of the bags to rub against the machine and break. Correction components are used to correct the deviation, but existing correction components limit and correct the bag workpiece by pushing it with baffles on both sides. Since the bag workpieces are made of relatively thin materials, they are prone to wrinkles. Furthermore, existing limit and correction mechanisms cannot automatically correct the deviation. Therefore, a correction component for a high-speed bag making machine is proposed. Summary of the Invention

[0003] To address at least one of the aforementioned technical shortcomings, the present invention provides a correction component for a high-speed bag-making machine, comprising: a support base, wherein the upper surface of the support base is sequentially provided with a limiting mechanism, a detection mechanism, a detection mechanism, a limiting mechanism, a correction mechanism, a limiting mechanism, a detection mechanism, a detection mechanism, and a limiting mechanism along the workpiece transmission direction; and a PLC controller is provided on one side of the support base for adaptively controlling the correction mechanism to perform correction, wherein the PLC controller automatically controls the correction mechanism based on the detection data of the detection mechanism.

[0004] Furthermore, several support rods are provided on both sides of the support base, and two through holes are provided on the side of each support rod. The limiting mechanism includes two rollers, and the shafts at both ends of the rollers are rotatably connected to the through holes of the support rods.

[0005] Furthermore, the testing mechanism includes a testing box fixed to the upper surface of the support base. The testing box has a through testing groove in the middle along the workpiece transport direction. A resistance groove is opened at the bottom of the testing groove, and a light source groove is opened at the top of the testing groove. A row of photoresistors perpendicular to the workpiece transport direction is provided at the bottom of the resistance groove, and a point light source corresponding to each photoresistor is provided at the top of the light source groove.

[0006] Furthermore, the correction mechanism includes two support blocks, the inner bottom sides of which are fixedly connected to both sides of the support base. A shaft is provided between the tops of the two support blocks, and several correction plates are arranged in a circle around the shaft. Adjacent correction plates are connected by elastic connecting pieces. Annular airbags are fixedly connected to both ends of the shaft. The outer wall of the airbag is fixedly connected to the inner surface of the correction plate. Air pumps are provided on the outer surface of the support blocks. The output end of the air pump is equipped with a solenoid valve, and the other end of the air pump is connected to the airbag.

[0007] Furthermore, the elastic coefficients on both sides of the airbag are less than the elastic coefficient of the outer wall of the airbag.

[0008] Furthermore, the elastic connecting piece is made of elastic rubber with an elastic coefficient greater than that of the outer wall of the airbag. A snap-fit ​​groove is provided in the middle of the surface where the correction plate connects with the elastic connecting piece. Snap-fit ​​blocks are provided at both ends of the elastic connecting piece. The cross-sections of the snap-fit ​​blocks and the snap-fit ​​grooves are T-shaped, and the snap-fit ​​blocks snap into the snap-fit ​​grooves.

[0009] Furthermore, the surface of the correction plate that contacts the workpiece is provided with a polytetrafluoroethylene layer.

[0010] Furthermore, the PLC controller includes control circuits for an air pump and a solenoid valve, as well as a detection circuit for a photoresistor.

[0011] Beneficial effects: 1. During correction, the front-end equipment transports the workpiece, and the rear-end equipment pulls the workpiece forward, causing it to move forward. The workpiece passes through the limit mechanism, detection mechanism, detection mechanism, limit mechanism, correction mechanism, limit mechanism, detection mechanism, detection mechanism, and limit mechanism in sequence. Two detection mechanisms in the same group measure the offset of the workpiece before and after, and then the PLC controller calculates the result. Finally, the PLC controller controls the correction mechanism to correct the offset of the workpiece, thus achieving automatic correction of the workpiece offset.

[0012] 2. During correction, the workpiece passes through the top of the correction plate. When the workpiece shifts to the right, the air pump on the right side operates, and the solenoid valve opens, causing the air pump to fill the air bladder on the right side. This inflates the air bladder, opening the right ends of several correction plates. At this time, the right side of the elastic connecting piece is stretched, and the correction plates form a frustum structure, with the right side larger than the left. This pushes the right edge of the workpiece upward from the lower right surface of the workpiece, increasing the stroke on the right side as the workpiece is conveyed forward. This corrects the part of the workpiece that has shifted to the right, thus completing the correction of the workpiece and preventing wrinkles from appearing after correction.

[0013] 3. The airbags at both ends of the correction component are constantly switching between inflating and deflating states, enabling continuous correction of the workpiece. Several correction plates continuously form a frustum structure with the left side larger than the right side, a frustum structure with the left side smaller than the right side, and a cylindrical structure with the same size on both sides, forming an automatic correction system. The system is automatically controlled by a PLC controller, and the offset is detected by two front-end detection mechanisms. The correction is then performed by the correction component, and the offset of the corrected workpiece is detected by two rear-end detection mechanisms.

[0014] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0027] Please refer to Figures 1 to 10 ;

[0028] This embodiment provides a correction component for a high-speed bag-making machine, referencing... Figure 1 and Figure 2The system includes: a support base 1, and a limit mechanism 2, a detection mechanism 3, a detection mechanism 3, a limit mechanism 2, a correction mechanism 4, a limit mechanism 2, a detection mechanism 3, a detection mechanism 3, and a limit mechanism 2 on the upper surface of the support base 1 along the workpiece conveying direction. A PLC controller 5 is provided on one side of the support base 1 for adaptive control of the correction mechanism 4. The PLC controller 5 automatically controls the correction mechanism 4 based on the detection data of the detection mechanism 3.

[0029] In specific implementation, at least one correction component consisting of limit mechanism 2, detection mechanism 3, detection mechanism 3, limit mechanism 2, correction mechanism 4, limit mechanism 2, detection mechanism 3, detection mechanism 3, limit mechanism 2 and PLC controller 5 shall be provided. Several correction components may be set up in the workpiece area to be corrected according to actual processing requirements.

[0030] Two detection mechanisms 3 form a group. The detection data of the same group of detection mechanisms 3 are calculated and processed by the PLC controller 5 to obtain the workpiece offset (offset angle, offset displacement).

[0031] The limiting mechanism 2 is used to ensure that the workpiece is on the same plane when it passes through the detection mechanism 3, the detection mechanism 3, and the correction mechanism 4.

[0032] During correction, the front-end equipment transports the workpiece, and the rear-end equipment pulls the workpiece forward, causing it to move forward. The workpiece passes through the following mechanisms in sequence: limit mechanism 2, detection mechanism 3, detection mechanism 3, limit mechanism 2, correction mechanism 4, limit mechanism 2, detection mechanism 3, detection mechanism 3, and limit mechanism 2. The two detection mechanisms 3 in the same group measure the offset of the workpiece before and after, and then calculate it through the PLC controller 5. Finally, the PLC controller 5 controls the correction mechanism 4 to correct the offset of the workpiece, realizing automatic correction of the workpiece offset.

[0033] Further reference Figure 2 The support base 1 has several support rods 101 on both sides, and each support rod 101 has two through holes on its side. The limiting mechanism 2 includes two rollers 201, and the shafts at both ends of the rollers 201 are rotatably connected to the through holes of the support rods 101.

[0034] In practice, during positioning, the workpiece is clamped by two rollers 201 to complete the positioning of the workpiece.

[0035] Further reference Figure 3 and Figure 4The detection mechanism 3 includes a detection box 301 fixed to the upper surface of the support base 1. The detection box 301 has a through detection groove 302 in the middle along the workpiece conveying direction. A resistance groove 303 is opened at the bottom of the detection groove 302. A light source groove 304 is opened at the top of the detection groove 302. A row of photoresistors 305 perpendicular to the workpiece conveying direction is provided at the bottom of the resistance groove 303. A point light source 306 corresponding to the photoresistors and parallel to each other is provided at the top of the light source groove 304.

[0036] In specific implementation, during the inspection, the two inspection mechanisms 3 in the same group measure the offset of the workpiece and obtain offset data one. The second inspection mechanism 3 then measures the offset of the workpiece and obtains offset data two. The distance between the two inspection mechanisms 3 is fixed. By calculating and comparing offset data one and offset data two, the offset of the workpiece during transportation can be calculated.

[0037] During inspection, the workpiece passes through the inspection groove 302, and the point light source 306 emits parallel light that shines on the photoresistor 305. The light from the point light source 306 in the area through which the workpiece passes is blocked by the workpiece, so that the photoresistor 305 in that area cannot receive light and its resistance changes. This allows the PLC controller 5 to obtain the width information and the boundary information on both sides of the workpiece, and then transmit the data to the PLC controller 5 for data calculation.

[0038] Further reference Figures 5 to 9 The correction mechanism 4 includes two support blocks 401. The bottom inner sides of the two support blocks 401 are fixedly connected to both sides of the support base 1. A shaft 402 is provided between the tops of the two support blocks 401. Several correction plates 403 are arranged in a circle around the shaft 402. Adjacent correction plates 403 are connected by elastic connecting pieces 404. Annular airbags 405 are fixedly connected to both ends of the shaft 402. The outer wall of the airbag 405 is fixedly connected to the inner surface of the correction plate 403. Air pumps 406 are provided on the outer surface of the support blocks 401. A solenoid valve 407 is provided at the output end of the air pump 406. The other end of the output end of the air pump 406 is connected to the airbag 405.

[0039] In practical implementation, during correction, the workpiece passes through the top of the correction plate 403. When the workpiece shifts to the right, the air pump 406 on the right side works, and the solenoid valve 407 opens, causing the air pump 406 to fill the airbag 405 on the right side with gas, causing the airbag 405 on the right side to expand and open the right end of the correction plates 403. At this time, the right side of the elastic connecting piece 404 is stretched, and the correction plates 403 form a frustum structure with the right side larger than the left side. The right edge of the workpiece is pushed up from the lower right surface of the workpiece, so that the right side stroke increases during the forward conveying of the workpiece, and the part of the workpiece that has shifted to the right is corrected, thus completing the correction of the workpiece and avoiding the appearance of wrinkles after the workpiece is corrected.

[0040] refer to Figure 11 The correction plate 403 lifts the left edge of the workpiece, which will slowly cause the workpiece to shift to the left. At this time, the two detection mechanisms 3 located at the rear end of the correction component 4 will detect the shift and enable the correction component 4 to automatically correct the workpiece shift. The air pump 406 slowly extracts the gas from the air bag 405 on the right side, causing the air bag 405 on the right side to extend and retract inward, causing several correction plates 403 to extend and retract inward, thus reducing the stroke of the right edge of the workpiece.

[0041] The airbags 405 at both ends of the correction component 4 are constantly switching between inflation and deflation, so as to realize the constant correction of the workpiece. Several correction plates 403 continuously form a frustum with a larger left side and a smaller right side, a frustum with a smaller left side and a larger right side, and a cylindrical structure with the same size on both sides, forming an automatic correction system. It is automatically controlled by a PLC controller, and the offset is detected by two front-end detection mechanisms 3. Then, the correction is performed by the correction component 4, and the offset of the corrected workpiece is detected by two rear-end detection mechanisms 3.

[0042] In practical use, at least one correction component needs to be set. The correction component can be used to perform step-by-step correction in several areas that need correction, or several correction components can be connected end to end for multi-level correction.

[0043] Furthermore, the elastic coefficients on both sides of the airbag 405 are less than the elastic coefficient of the outer wall of the airbag 405.

[0044] In practice, after the airbag 405 is inflated with gas, the outer wall of the airbag 405 will first expand outward, pushing the correction plate 403 to extend and retract inward.

[0045] Furthermore, the elastic connecting piece 404 is made of elastic rubber, and its elastic coefficient is greater than that of the outer wall of the airbag 405. A snap-fit ​​groove 431 is provided in the middle of the surface where the corrective plate 403 connects with the elastic connecting piece 404. Both ends of the elastic connecting piece 404 are provided with snap-fit ​​blocks 441. The cross-sections of the snap-fit ​​blocks 441 and the snap-fit ​​groove 431 are T-shaped, and the snap-fit ​​blocks 441 and the snap-fit ​​groove 431 snap-fit ​​together.

[0046] In practical implementation, the snap-fit ​​block 441 and snap-fit ​​groove 431 make it easy to replace the elastic connecting piece 404.

[0047] Furthermore, the surface of the correction plate 403 that contacts the workpiece is provided with a polytetrafluoroethylene layer;

[0048] In practice, the surface of the correction plate 403 is made smoother by adding a polytetrafluoroethylene layer.

[0049] Furthermore, the PLC controller 5 is equipped with a control circuit for the air pump 406 and the solenoid valve 407, and the PLC controller 5 is equipped with a detection circuit for the photoresistor 305.

[0050] In practical implementation, the air pump 406 and solenoid valve 407 are controlled by the PLC controller 5, and the PLC controller 5 receives data on whether the photosensitive motor 305 is illuminated, and obtains relevant data.
