Description

Technical Field

[0001] The present invention relates to the technical field of test paper packaging, and particularly to an integrated device for test paper printing, packaging, and postal envelope information pasting. Background Art

[0002] For a long time, test papers required for examinations have been printed in batches by offset printing and manually sorted and bagged, and then transported to various test centers and examination rooms through logistics. In the past ten-odd years, information barcodes have emerged. In some examinations, candidates need to manually paste the distributed barcodes to fixed positions on the test papers, and in some examinations, the test papers come with information barcodes.

[0003] Obviously, the traditional test paper printing method consumes too much time from question making to printing and production, which in turn causes inevitable cost waste. Accidents such as mistakes in manual sorting and the risk of candidates mis-pasting barcodes also affect the overall efficiency and fairness of examination affairs to a certain extent. Therefore, developing an integrated device for test paper printing, packaging, and postal envelope information pasting can achieve full automation from test paper production to packaging and mailing, greatly improving efficiency and ensuring data security.

[0004] Chinese Patent Publication No.: CN106739573A discloses an automatic stamping machine and its stamping method, including a machine body. A test paper transportation unit, a printing unit, and an information processing and control unit are provided on the machine body. The test paper transportation unit and the printing unit are respectively connected to the information processing and control unit. Under the control of the information processing and control unit, the test paper transportation unit transports the test paper bag to below the printing unit, and the printing unit prints the transported test paper bag. The printing unit includes a vertically arranged optical rod and a vertical lead screw. A linkage rod is sleeved on the optical rod. The linkage rod is in threaded cooperation with the vertical lead screw to form a lead screw-nut mechanism. The vertical lead screw is driven by a vertical lead screw motor. A horizontal reciprocating lead screw, a nozzle, and a hollow stamp template are provided on the linkage rod. The horizontal reciprocating lead screw is driven by a horizontal lead screw motor. The nozzle is in threaded cooperation with the horizontal reciprocating lead screw. The stamp template is located below the nozzle, and the hollow part of the stamp template is within the spraying range of the nozzle. It can be seen that the automatic stamping machine and its stamping method have the following problems:

[0005] It only controls the stamping process of the test paper bag in the test paper printing, packaging, and postal envelope, and has a low degree of automation and intelligence for the overall process of test paper printing, test paper packaging, and postal envelope. Summary of the Invention

[0006] Therefore, the present invention provides an integrated device for test paper printing, packaging, and postal envelope information pasting to overcome the problems in the prior art that only controls a single process in test paper printing, packaging, and postal envelope, and has a low degree of automation and intelligence for the overall process.

[0007] To achieve the above object, the present invention provides an integrated device for printing, encapsulating test papers and pasting postal envelope information, including:

[0008] A detailed waybill printing and pasting station, which is located on the top of the envelope hinge mechanism, includes a thermal waybill, a waybill printer, a conveying roller shaft, a receiving roller shaft and a pressure roller shaft, and is used to receive the mailing information of the test paper, print the detailed waybill and paste it on the envelope;

[0009] A detection component, which is connected to the detailed waybill printing and pasting station, is used to obtain the conveying pressure borne by several of the pressure roller shafts and the force angle of the pressure roller shaft according to the initial detection period, detect the rotation speeds of the conveying roller shaft and the receiving roller shaft, and store the moving speed of the print head;

[0010] An analysis unit, which is connected to the detection component, can determine the winding tension according to the stretching state of the thermal waybill, or evaluate the consumption degree of the thermal waybill according to the tangent angle to adjust the determination standard of the stretching state, or judge whether the rotation speeds match according to the linear velocity difference and determine the reason for the mismatch, or determine the rotation speed, the moving speed of the print head and the initial detection period according to the volatility of the moving speed of the print head and the working state of the waybill printer;

[0011] An adjustment unit, which is connected to the analysis unit, can adjust the winding tension, rotation speed and moving speed of the print head of the device according to the parameters determined by the analysis unit;

[0012] A print head is arranged inside the waybill printer.

[0013] Further, the analysis unit analyzes and compares the conveying pressure data obtained by the detection component to determine the stretching state of the thermal waybill;

[0014] The analysis unit compares the conveying pressure with the standard value, and judges whether the thermal waybill is in the first stretching state, the second stretching state or the third stretching state according to the comparison result;

[0015] When the analysis unit determines that the thermal waybill is in the first stretching state or the second stretching state, it controls the adjustment unit to adjust the winding tension accordingly;

[0016] The standard value is divided into a first standard value and a second standard value.

[0017] Further, when the analysis unit determines that the thermal waybill is in the first stretching state, it calculates the tangent angle of the thermal waybill relative to the pressure roller shaft according to the force angle obtained by the detection component;

[0018] The analysis unit compares the tangent angle with a fixed angle, and determines the consumption degree of the cylinder formed by the thermal sensitive surface sheets on the conveying roller shaft according to the comparison result. The analysis unit maintains the tensile state of the thermal sensitive surface sheets according to the consumption degree, or adjusts the determination criterion of the tensile state to perform a secondary determination on the tensile state of the thermal sensitive surface sheets.

[0019] Further, the detection component obtains the rotation speeds of the conveying roller shaft and the receiving roller shaft. When the analysis unit determines that the thermal sensitive surface sheets are in the third tensile state, it can calculate the linear velocity difference according to the rotation speeds.

[0020] The analysis unit compares the absolute value of the linear velocity difference with a difference evaluation value, and determines whether the rotation speeds of the conveying roller shaft and the receiving roller shaft match according to the comparison result.

[0021] When the analysis unit determines that the rotation speeds of the conveying roller shaft and the receiving roller shaft do not match, it controls the adjustment unit to adjust the rotation speeds of the conveying roller shaft and the receiving roller shaft and determines the reason for the non-matching rotation speeds.

[0022] Further, when the analysis unit determines that the linear velocity of the conveying roller shaft is greater than the linear velocity of the receiving roller shaft, it controls the adjustment unit to increase the rotation speed of the receiving roller shaft according to the absolute value of the linear velocity difference.

[0023] When the analysis unit determines that the linear velocity of the conveying roller shaft is less than the linear velocity of the receiving roller shaft, it controls the adjustment unit to increase the rotation speed of the conveying roller shaft according to the absolute value of the linear velocity difference.

[0024] Further, the detection component obtains the rotation speeds of the conveying roller shaft and the receiving roller shaft according to an initial detection period. The analysis unit calculates the rotation speed increase ratio of the conveying roller shaft and the rotation speed decrease ratio of the receiving roller shaft according to the rotation speed data.

[0025] When the rotation speed increase ratio is not equal to the rotation speed decrease ratio, the analysis unit determines that the reason for the non-matching rotation speeds of the conveying roller shaft and the receiving roller shaft is that the rotation speed increase ratio and the rotation speed decrease ratio do not match.

[0026] Further, the detection component obtains a plurality of moving speed data of the print head according to an initial detection period. When the thermal sensitive surface sheets are in the third tensile state and the rotation speeds of the conveying roller shaft and the receiving roller shaft match, the analysis unit analyzes the obtained plurality of moving speed data and calculates the variance value of the plurality of moving speeds.

[0027] The analysis unit compares the variance value with the standard variance, and determines based on the comparison result that the volatility of the moving speed data of the print head exceeds the normal range, the label printer is in the first working state, or the volatility of the moving speed data of the print head is within the normal range, and the label printer is in the second working state;

[0028] When the label printer is in the first working state, the analysis unit controls the adjustment unit to reduce the rotation speeds of the conveying roller shaft and the receiving roller shaft according to the ratio of the standard variance to the variance value, and correspondingly reduce the initial detection period;

[0029] When the label printer is in the second working state, the analysis unit controls the adjustment unit to increase the moving speed of the print head according to the ratio of the standard variance to the variance value, and correspondingly increase the rotation speeds of the conveying roller shaft and the receiving roller shaft.

[0030] Further, when the thermal label is in the second stretching state, the analysis unit calculates the average pressure according to the conveying pressures of the two pressure roller shafts obtained by the detection assembly, and compares the average pressure with the critical value;

[0031] The analysis unit determines, based on the comparison result of the average pressure and the critical value, whether the winding tension borne by the thermal label exceeds the bearing range, whether there is a risk of damage or deformation and wrinkling of the thermal label, and determines the specific situation of the winding tension adjustment.

[0032] Further, when the analysis unit determines that the winding tension borne by the thermal label is within the bearing range, it draws a pressure change curve according to the average pressure and calculates the derivative function value of the pressure change curve;

[0033] When the derivative function value is less than zero, the analysis unit determines that the winding tension borne by the thermal label is decreasing after adjusting the winding tension;

[0034] When the derivative function value is greater than or equal to zero, the analysis unit determines that the winding tension borne by the thermal label remains unchanged or is increasing after adjusting the winding tension, the thermal label is jammed, and controls the adjustment unit to control the indicator light to flash to emit a warning signal and control the device to stop urgently.

[0035] Further, the integrated device further includes,

[0036] An envelope loading box, which is a hollow structure and is used to place envelopes to be used for encapsulation;

[0037] An envelope sending mechanism, which is connected to the envelope loading box and is used to send several envelopes to be used for encapsulation to the internal envelope waiting area one by one;

[0038] An envelope opening mechanism, which is connected to the envelope sending mechanism and is used to open a single envelope in the envelope waiting area;

[0039] A test paper loading mechanism, which is connected to the envelope opening mechanism and is used for double recognition verification of the test paper. After the verification is passed, the test paper is loaded into the opened envelope.

[0040] An envelope hinge mechanism, which is located on the side of the test paper loading mechanism and is used for tearing the off-line paper on the envelope and sealing the envelope hinge.

[0041] An inspection station, which is located on the side of the envelope hinge mechanism and is used for verifying the express waybill number on the detail list.

[0042] A display, which is a data display of an integrated device and is located on the top of the receiving box.

[0043] A receiving box, which is located on the side of the inspection station and is used for storing the sealed envelopes.

[0044] A lifting mechanism, which is connected to the test paper loading mechanism and is used for transporting the test paper to the test paper loading mechanism.

[0045] A docking transition mechanism, which is connected to the lifting mechanism and is used for docking the test paper on the conveyor belt to the lifting elevator.

[0046] A roller mechanism, which is located above the conveyor belt and is used for flattening the folded test paper.

[0047] A conveying mechanism, which is used for accessing the printed test paper to the conveyor belt and moving the test paper through the conveyor belt.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows. The present invention is applicable to the need for automatic packaging of test papers, and can realize functions such as sealed packaging, label printing, labeling, and release paper recycling of test papers and mailing materials. It replaces manual packaging with an automated packaging device, reduces the workload of packaging, improves work efficiency, and reduces error rates; it has a high degree of integration, integrating test paper production and automatic test paper mailing. It has a high operating efficiency, and the test paper production and packaging speed is ≥260 envelopes / hour. It has a high degree of accuracy, and the docking realizes a full-process closed-loop accurate printing and packaging. Based on the OCR and barcode double recognition verification technology, zero errors occur in printing and packaging; the present invention judges the stretching state of the thermal sensitive label by the conveying pressure borne by several pressure rollers, avoiding the situation that the thermal sensitive label is loosened or over-tensioned due to too high or too low winding tension, and increasing the accuracy of the mailing information printing process.

[0049] Furthermore, as the thermal label is consumed, the angle between the thermal label and the adjacent pressure roller changes accordingly. Therefore, the pressure value borne by the adjacent pressure roller is also constantly changing. Moreover, due to the angle of the thermal label, the conveying pressure borne by the adjacent pressure roller is the smallest. According to this application scenario of the mailing station, the present invention determines the consumption degree of the thermal label through the tangent angle, maintains a determined stretching state of the thermal label according to the consumption degree, or adjusts the determination criterion of the stretching state to perform a secondary determination on the stretching state of the thermal label, increasing the accuracy and adaptability of determining the stretching state and avoiding inaccurate determination resulting in the thermal label being in a poor stretching state for a long time.

[0050] Furthermore, in the application scenario of this device, since the radius of the cylinder formed by the thermal label on the conveying roller and the receiving roller changes continuously with consumption, the linear speeds of the conveying roller and the receiving roller need to be matched. When the thermal label is in an appropriate stretching state, the present invention determines whether the rotational speeds are matched by the difference in the linear speeds of the conveying roller and the receiving roller, and correspondingly determines the reason for the unmatched rotational speeds according to the rising ratio of the rotational speed of the conveying roller and the falling ratio of the rotational speed of the receiving roller, avoiding the thermal label being stretched or loosened due to unmatched linear speeds, which affects the printing process of the mailing information, and increasing the stability and accuracy during the operation of the device.

[0051] Furthermore, when the difference in linear speeds is less than the difference evaluation value but not equal to zero, the print head is in direct contact with the thermal paper during printing, and the print head needs to move quickly to ensure the continuity and clarity of the printed content. Therefore, when the thermal label is thermally printed by the label printer, the moving speed of the print head is affected by the moving speed of the thermal label. The present invention reflects the working state of the printer through the volatility of the moving speed of the print head. When the volatility is large, it reduces the moving speed of the thermal label to reduce the degree to which the moving speed of the print head is affected by the moving speed of the thermal label, and increases the determination frequency of the working state of the printer and the stretching state of the thermal label, thereby increasing the monitoring intensity of the integrated device, more closely monitoring the details of the label printing and pasting process, avoiding breakpoints or unclear situations during the thermal label printing process, reducing the probability of inaccurate mailing information that may occur in the integrated device, and increasing the accuracy of the oil seal information pasting; at the same time, when the volatility is small, it ensures the maximum moving speed of the print head under the premise of volatility, matches the maximum rotational speeds of the conveying roller and the receiving roller, and optimizes the printing efficiency of the label printer.

[0052] Furthermore, the main function of the pressure roller shaft is to ensure that the thermal paper can be closely attached to the print head during the printing process, avoiding affecting the printing quality due to paper movement or wrinkling. When the thermal label is in a tensioned state, the present invention determines the winding tension borne by the thermal label according to the average speed of the pressure roller shaft that bears the maximum conveying pressure, determines that there is a risk of damage or deformation and wrinkling of the thermal label caused by the winding tension, and accordingly issues a warning signal, and determines the specific situation of the winding tension adjustment according to the change trend of the winding tension, avoiding the phenomenon of thermal label jamming, and improving the adaptability of the device to risk judgment and the accuracy of adjusting device parameters.

[0063] An embodiment of the present invention provides an integrated device for printing, packaging and pasting postal envelope information, including:

[0064] An envelope loading box 1, which is a hollow structure and is used to place envelopes to be used for packaging;

[0065] An envelope sending mechanism 2, which is connected to the envelope loading box and is used to send several envelopes to be used for packaging to the internal envelope waiting area one by one;

[0066] An envelope opening mechanism 3, which is connected to the envelope sending mechanism and is used to open a single envelope in the envelope waiting area;

[0067] A test paper loading mechanism 4, which is connected to the envelope opening mechanism and is used to perform double recognition verification of OCR and barcodes on the test paper. After the verification is passed, the test paper is loaded into the opened envelope;

[0068] An envelope hinge mechanism 5, which is located on the side of the test paper loading mechanism and is used to automatically tear the off-line paper on the envelope and seal the envelope hinge;

[0069] The detailed waybill printing and pasting station 6 is located at the top of the envelope hinge mechanism and includes a thermal waybill, a waybill printer 61, a conveying roller shaft 62, a receiving roller shaft 63 and a pressure roller shaft 64, which are used to receive the mailing information of the test papers, print the detailed waybills and paste them onto the envelopes;

[0070] The verification station 7 is located on the side of the envelope hinge mechanism and is used to perform OCR photo verification on the express waybill numbers on the detailed waybills;

[0071] The display 8 is a data display of the integrated device and is located on the top of the receiving box;

[0072] The receiving box 9 is located on the side of the verification station and is used to store the sealed envelopes;

[0073] The lifting mechanism 10 is connected to the test paper loading mechanism and is used to transport the test papers to the test paper loading mechanism;

[0074] The docking and transition mechanism 11 is connected to the lifting mechanism and is used to dock the test papers on the conveyor belt to the lifting elevator;

[0075] The roller mechanism 12 is located above the conveyor belt and is used to flatten the folded test papers;

[0076] The conveying mechanism 13 is used to access the printed test papers onto the conveyor belt and move the test papers through the conveyor belt;

[0077] The detection component is connected to the detailed waybill printing and pasting station and is used to obtain the conveying pressures borne by several of the pressure roller shafts and the stress angles of the pressure roller shafts at the initial detection period, detect the rotation speeds of the conveying roller shaft and the receiving roller shaft, and store the moving speed of the print head;

[0078] The analysis unit is connected to the detection component and can determine the winding tension adjustment method according to the stretching state of the thermal waybill, or evaluate the consumption degree of the thermal waybill according to the tangent angle to adjust the judgment standard of the stretching state, or judge whether the rotation speeds match according to the linear velocity difference and determine the reasons for the mismatch, or determine the rotation speed, the moving speed of the print head and the initial detection period according to the volatility of the moving speed of the print head and the working state of the waybill printer;

[0079] The adjustment unit is connected to the analysis unit and can adjust the winding tension, rotation speed and moving speed of the print head of the equipment according to the parameters determined by the analysis unit;

[0080] A print head is arranged inside the waybill printer.

[0081] In this embodiment, during the process of printing and pasting the detailed waybill, the thermal waybill is wound around the conveying roller shaft in a cylindrical shape. The conveying roller shaft outputs the thermal waybill through two pressure roller shafts and enters the waybill printer for printing by the print head. After printing, it passes through four pressure roller shafts and is output to the receiving roller shaft to be wound into a cylindrical shape.

[0082] The detection component detects the conveying pressure borne by several pressure roller shafts according to the initial detection period. The analysis unit compares any conveying pressure with the standard value, and the standard value is divided into a first standard value and a second standard value, and the second standard value is greater than the first standard value.

[0083] If any conveying pressure is less than the first standard value, the analysis unit determines that the thermal waybill is in the first stretching state, the thermal waybill is loose, and controls the adjustment unit to adjust the winding tension.

[0084] Specifically, the analysis unit increases the winding tension according to the ratio of the first standard value to the conveying pressure.

[0085] If any conveying pressure is greater than the first standard value and less than the second standard value, the analysis unit determines that the thermal waybill is in the third stretching state, and the winding tension borne by the thermal waybill is in an appropriate range.

[0086] If any conveying pressure is greater than the second standard value, the analysis unit determines that the thermal waybill is in the second stretching state, the thermal waybill is taut, and controls the adjustment unit to adjust the winding tension.

[0087] Specifically, the analysis unit controls the adjustment unit to reduce the winding tension according to the ratio of the second standard value to the conveying pressure.

[0088] Among them, the standard value is a preset value set according to the material of the thermal waybill and the historical data of the conveying pressure borne by the pressure roller shaft.

[0089] Specifically, the present invention is applicable to the need of automatically encapsulating test papers, and can realize functions such as the secure encapsulation, label printing, labeling, and release paper recycling of test papers and mailing materials. It replaces manual encapsulation with an automated encapsulation device, reduces the workload of encapsulation, improves work efficiency, and reduces the error rate; it has a high degree of integration, integrating test paper production and automatic postal sealing of test papers, with high operating efficiency, a test paper production and sealing speed of ≧260 envelopes per hour, high precision, realizing a full-process closed-loop precise printing and packaging through docking, and achieving zero errors in printing and packaging based on OCR and barcode dual recognition verification technology; the present invention judges the stretching state of the thermal waybill by the conveying pressure borne by several pressure roller shafts, avoiding the situation that the thermal waybill is loose or over-tightened due to too high or too low winding tension, and increasing the accuracy of the postal envelope information printing process.

[0090] In this embodiment, as the thermal sheet is output and printed, the radius of the cylinder formed by the thermal sheet on the conveying roller decreases, and the angle of the thermal sheet on the pressure roller adjacent to the conveying roller changes accordingly; at the same time, the radius of the cylinder formed by the thermal sheet on the receiving roller increases, and the angle of the thermal sheet on the pressure roller adjacent to the receiving roller changes accordingly.

[0091] When the thermal face sheet is in the first stretched state, the detection component detects the conveying pressure and the force angle borne by the pressure roller near the conveying roller, and the analysis unit calculates the tangent angle of the thermal face sheet perpendicular to the force angle according to the force angle;

[0092] If the tangent angle relative to the horizontal plane is less than the fixed angle, the analysis unit determines that the cylinder formed by the heat-sensitive sheet on the conveying roller is at a first consumption level, and the stretching state of the heat-sensitive sheet remains unchanged;

[0093] If the tangent angle is greater than the fixed angle, the analysis unit determines that the cylinder formed by the heat-sensitive sheet on the conveying roller is at a second consumption level, adjusts the first standard value, and performs a second determination on the stretching state of the heat-sensitive sheet after the adjustment;

[0094] Specifically, the analysis unit reduces the first standard value according to the ratio of the fixed angle to the tangent angle;

[0095] The fixed angle can be set according to the tangent angle when the device is installed into the thermal surface monotube and specific needs.

[0096] Specifically, as the thermal face sheet is consumed, the angle between the thermal face sheet and the adjacent pressure roller changes accordingly, so the pressure value borne by the adjacent pressure roller is also constantly changing, and due to the angle of the thermal face sheet, the conveying pressure borne by the adjacent pressure roller is the smallest; according to this application scenario of the mailing station, the present invention judges the degree of consumption of the thermal face sheet by the tangent angle, maintains a certain stretching state of the thermal face sheet according to the degree of consumption, or adjusts the judgment standard of the stretching state, and performs a secondary judgment on the stretching state of the thermal face sheet, thereby increasing the accuracy and adaptability of judging the stretching state, and avoiding the thermal face sheet being in a bad stretching state for a long time due to inaccurate judgment.

[0097] In this embodiment, the angular velocity of the conveying roller increases continuously as the radius of the cylinder decreases, and the roller rotates faster and faster, while the angular velocity of the receiving roller decreases continuously as the radius of the cylinder decreases, and the roller rotates slower and slower.

[0098] When the thermal face sheet is in the third stretching state, the detection component detects the rotation speed of the transmission roller and the receiving roller in real time, and the analysis unit calculates the linear velocity difference between the transmission roller and the receiving roller according to the linear velocity = angular velocity × radius, angular velocity = 2Π × rotation speed;

[0099] If the absolute value of the linear velocity difference is less than or equal to the difference evaluation value, the analysis unit determines that the rotational speeds of the conveying roller shaft and the receiving roller shaft match;

[0100] If the absolute value of the linear velocity difference is greater than the difference evaluation value, the analysis unit determines that the rotational speeds of the conveying roller shaft and the receiving roller shaft do not match, controls the adjustment unit to adjust the rotational speeds of the conveying roller shaft and the receiving roller shaft, and determines the reason for the non-matching rotational speeds;

[0101] Specifically, if the linear velocity of the conveying roller axis is greater than the linear velocity of the receiving roller axis, the analysis unit controls the adjustment unit to increase the rotational speed of the receiving roller shaft according to the absolute value of the linear velocity difference;

[0102] If the linear velocity of the conveying roller axis is less than the linear velocity of the receiving roller axis, the analysis unit controls the adjustment unit to increase the rotational speed of the conveying roller shaft according to the absolute value of the linear velocity difference.

[0103] The detection component detects and records the rotational speeds of the conveying roller shaft and the receiving roller shaft in real time. The analysis unit calculates the rotational speed increase ratio of the conveying roller shaft and the rotational speed decrease ratio of the receiving roller shaft according to the initial detection period.

[0104] If the rotational speed increase ratio is not equal to the rotational speed decrease ratio, the analysis unit determines that the reason for the non-matching rotational speeds of the conveying roller shaft and the receiving roller shaft is that the rotational speed increase ratio and the rotational speed decrease ratio do not match.

[0105] Specifically, in the application scenario of this device, since the radius of the cylinder formed by the thermal-sensitive surface sheets on the conveying roller shaft and the receiving roller shaft changes continuously with consumption, the linear velocities of the conveying roller shaft and the receiving roller shaft need to match. In the present invention, when the thermal-sensitive surface sheet is in an appropriate stretched state, it is determined whether the rotational speeds match based on the linear velocity difference between the conveying roller shaft and the receiving roller shaft, and the reason for the non-matching rotational speeds is determined according to the rotational speed increase ratio of the conveying roller shaft and the rotational speed decrease ratio of the receiving roller shaft, avoiding the stretching or loosening of the thermal-sensitive surface sheet caused by the non-matching linear velocities, which affects the printing process of the postal envelope information, and increasing the stability and accuracy of the device operation process.

[0106] In this embodiment, the print head is the core component of the label printer, responsible for printing text or patterns on the thermal paper. Its working principle is to heat the coating of the thermal paper through a heating element (such as a semiconductor), causing a chemical reaction in the coating to form visible patterns or text. The print head prints the information in a dot matrix form on the paper by precisely controlling the position and temperature of the heating points.

[0107] When the thermal-sensitive surface sheet is in the third stretched state and the rotational speeds of the conveying roller shaft and the receiving roller shaft match,

[0108] The detection component records the moving speed of the print head in the label printer in real time, and the analysis unit analyzes a number of moving speed data of the print head within the initial detection period and calculates the variance value of the number of moving speeds;

[0109] If the variance value is greater than the standard variance, the analysis unit determines that the volatility of the moving speed data of the print head exceeds the normal range, and the label printer is in the first working state;

[0110] If the variance value is less than the standard variance, the analysis unit determines that the volatility of the moving speed data of the print head is within the normal range, and the label printer is in the second working state;

[0111] When the label printer is in the first working state, the analysis unit controls the adjustment unit to reduce the rotation speeds of the conveying roller shaft and the receiving roller shaft according to the ratio of the standard variance to the variance value, and correspondingly reduce the initial detection period;

[0112] When the label printer is in the second working state, the analysis unit controls the adjustment unit to increase the moving speed of the print head according to the ratio of the standard variance to the variance value, and correspondingly increase the rotation speeds of the conveying roller shaft and the receiving roller shaft.

[0113] Among them, the standard variance is a preset value set according to the printing parameters of the label printer and the printing requirements of the oil seal information.

[0114] Specifically, the linear velocity difference is less than the difference evaluation value but not equal to zero. The print head is in direct contact with the thermal paper during printing, and the print head needs to move quickly to ensure the continuity and clarity of the printed content. Therefore, in the case of thermal printing of the thermal label through the label printer, the moving speed of the print head is affected by the moving speed of the thermal label; the present invention reflects the working state of the printer through the volatility of the moving speed of the print head. When the volatility is large, the moving speed of the thermal label is reduced, thereby reducing the degree to which the moving speed of the print head is affected by the moving speed of the thermal label, and increasing the determination frequency of the printer working state and the stretching state of the thermal label, thereby increasing the monitoring intensity of the integrated device, more closely monitoring the details of the label printing and pasting process, avoiding breakpoints or unclear situations during the thermal label printing process, reducing the probability of inaccurate postal seal information that may occur in the integrated device, and increasing the accuracy of oil seal information pasting; at the same time, when the volatility is small, the maximum moving speed of the print head is determined under the premise of ensuring volatility, matching the maximum rotation speeds of the conveying roller shaft and the receiving roller shaft, and optimizing the printing efficiency of the label printer.

[0115] In this embodiment, there are two pressure roller shafts that bear greater pressure under the tensioned state than other pressure roller shafts. When the thermal label is in the second stretching state, the detection component detects the conveying pressure of the two pressure roller shafts, and the analysis unit calculates the average pressure;

[0116] If the average pressure is greater than the critical value, the analysis unit determines that the winding tension borne by the thermal sensitive surface sheet exceeds the bearing range, and there is a risk of damage to the thermal sensitive surface sheet. The regulating unit is controlled to make the indicator light flash to emit an alarm signal, and the device is controlled to stop urgently.

[0117] If the average pressure is less than the critical value, the analysis unit determines that the winding tension borne by the thermal sensitive surface sheet is within the bearing range, and there is a risk of deformation and wrinkling of the thermal sensitive surface sheet, and determines the specific situation of the winding tension adjustment.

[0118] Wherein, the critical value is a preset value set according to the material of the thermal sensitive surface sheet.

[0119] When the winding tension borne by the thermal sensitive surface sheet is within the bearing range, the analysis unit draws a pressure change curve of the average pressure.

[0120] If the derivative value is less than zero, the analysis unit determines that the winding tension borne by the thermal sensitive surface sheet is gradually decreasing after adjusting the winding tension.

[0121] If the derivative value is greater than or equal to zero, the analysis unit determines that the winding tension borne by the thermal sensitive surface sheet remains unchanged or is gradually increasing after adjusting the winding tension, and the thermal sensitive surface sheet is jammed. The regulating unit is controlled to make the indicator light flash to emit a warning signal, and the device is controlled to stop urgently.

[0122] Specifically, the main function of the pressure roller shaft is to ensure that the thermal sensitive paper can be closely attached to the print head during the printing process, and to avoid affecting the printing quality due to paper movement or wrinkling. In the present invention, when the thermal sensitive surface sheet is in a tensioned state, the winding tension borne by the thermal sensitive surface sheet is judged according to the average speed of the pressure roller shaft that bears the maximum conveying pressure, and it is determined that there is a risk of damage or deformation and wrinkling of the thermal sensitive surface sheet caused by the winding tension. Accordingly, a warning signal is issued, and the specific situation of the winding tension adjustment is determined according to the change trend of the winding tension, so as to avoid the phenomenon of paper jamming of the thermal sensitive surface sheet, and improve the adaptability of the device to risk judgment and the accuracy of adjusting the device parameters.
