Description

Technical Field

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

[0002] For a long time, the test papers needed for the exams were printed in batches, sorted and bagged manually, and then transported to various test sites through logistics. In the past decade or so, information barcodes have begun to appear. Some exams require candidates to manually paste the distributed barcodes on fixed positions on the test papers, while some exam papers come with information barcodes.

[0003] It is obvious that the traditional test paper printing method consumes too much time from question preparation to printing, which leads to inevitable cost waste. The mistakes of manual sorting and the risk of candidates affixing barcodes by mistake also affect the overall efficiency and fairness of the examination work to a certain extent. Therefore, the development of an integrated equipment that integrates test paper printing, packaging and postal information affixing can realize the 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 a stamping method thereof, including a machine body, on which a test paper transport unit, a printing unit, and an information processing and control unit are provided. The test paper transport 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 transport unit transports the test paper bag to the bottom of the printing unit, and the printing unit prints the delivered test paper bag. The printing unit includes an upright light rod and a vertical screw rod. A linkage rod is sleeved on the light rod. The linkage rod and the vertical screw rod are threaded to form a screw nut mechanism. The vertical screw rod is driven by a vertical screw rod motor. A transverse reciprocating screw rod, a nozzle, and a hollowed-out seal template are provided on the linkage rod. The transverse reciprocating screw rod is driven by a transverse screw rod motor. The nozzle and the transverse reciprocating screw rod are threaded to cooperate. The seal template is located below the nozzle, and the hollowed-out part of the seal template is within the spraying range of the nozzle. It can be seen that the automatic stamping machine and the stamping method thereof have the following problems: Only the test paper bag stamping process in the test paper printing, sealing and mailing is controlled, and the degree of automation and intelligence of the overall process of test paper printing, sealing and mailing is low. Summary of the invention

[0005] To this end, the present invention provides an integrated device that integrates test paper printing, packaging and mailing information pasting, so as to overcome the problem that the prior art only controls a single process in test paper printing, packaging and mailing, and has a low degree of automation and intelligence for the overall process.

[0006] To achieve the above object, the present invention provides an integrated device for printing, packaging and pasting information on mailing envelopes, comprising: The detailed sheet printing and pasting station is located on the top of the envelope hinge mechanism and includes a thermal sheet, a sheet printer, a transmission roller, a receiving roller and a pressure roller, and is used to receive the mailing information of the test paper, print the detailed sheet and paste it on the envelope; A detection component connected to the detailed sheet printing and pasting station, used to obtain the conveying pressures and force angles of the pressure roller shafts according to the initial detection cycle, detect the rotation speeds of the conveying roller shaft and the receiving roller shaft, and store the moving speed of the print head; An analysis unit connected to the detection assembly, capable of determining the winding tension according to the stretching state of the thermal sheet, or evaluating the degree of consumption of the thermal sheet according to the tangent angle to adjust the criterion for determining the stretching state, or determining whether the rotation speed matches and determining the cause of the mismatch according to the linear speed difference, or determining the rotation speed, the print head movement speed and the initial detection period according to the fluctuation of the print head movement speed and the working state of the sheet printer; an adjustment unit connected to the analysis unit and capable of adjusting the winding tension, rotation speed and print head movement speed of the device according to the parameters determined by the analysis unit; A print head is arranged inside the label printer.

[0007] Furthermore, the analysis unit analyzes and compares the conveying pressure data acquired by the detection component to determine the stretching state of the thermal face sheet; The analysis unit compares the conveying pressure with a standard value, and determines whether the thermal surface sheet is in the first stretching state, the second stretching state, or the third stretching state according to the comparison result; When the analyzing unit determines that the heat-sensitive surface sheet is in the first stretching state or the second stretching state, the adjusting unit controls the adjusting unit to adjust the winding tension accordingly; The standard value is divided into a first standard value and a second standard value.

[0008] Furthermore, when determining that the thermal surface sheet is in the first stretched state, the analysis unit calculates the tangent angle of the thermal surface sheet relative to the pressure roller according to the force angle obtained by the detection component; The analysis unit compares the tangent angle with the fixed angle, and determines the degree of consumption of the cylinder formed by the thermal surface sheet on the conveying roller according to the comparison result. The analysis unit maintains the stretched state of the thermal surface sheet according to the degree of consumption, or adjusts the judgment standard of the stretched state to perform a secondary judgment on the stretched state of the thermal surface sheet.

[0009] Furthermore, the detection component obtains the rotation speeds of the transmission roller and the receiving roller, and the analysis unit can calculate the linear speed difference according to the rotation speeds when determining that the thermal surface sheet is in the third stretching state; The analysis unit compares the absolute value of the linear velocity difference with the difference evaluation value, and determines whether the rotation speeds of the transmission roller and the receiving roller match according to the comparison result; When determining that the rotation speeds of the conveying roller and the receiving roller do not match, the analyzing unit controls the adjusting unit to adjust the rotation speeds of the conveying roller and the receiving roller and determines the cause of the rotation speed mismatch.

[0010] Further, when the analyzing unit determines that the linear speed of the conveying roller is greater than the linear speed of the receiving roller, the adjusting unit is controlled to increase the rotation speed of the receiving roller according to the absolute value of the linear speed difference; When the analyzing unit determines that the linear speed of the conveying roller is lower than the linear speed of the receiving roller, the adjusting unit controls the adjusting unit to increase the rotation speed of the conveying roller according to the absolute value of the linear speed difference.

[0011] Further, the detection component obtains the rotation speeds of the transmission roller and the receiving roller according to the initial detection cycle, and the analysis unit calculates the increase ratio of the transmission roller rotation speed and the decrease ratio of the receiving roller rotation speed according to the rotation speed data; When the speed increase ratio is not equal to the speed decrease ratio, the analyzing unit determines that the reason why the speeds of the conveying roller and the receiving roller do not match is that the speed increase ratio does not match the speed decrease ratio.

[0012] Furthermore, the detection component acquires a plurality of movement speed data of the print head according to the initial detection cycle, and the analysis unit analyzes the acquired plurality of movement speed data when the thermal sheet is in the third stretching state and the rotation speeds of the transmission roller and the receiving roller match, and calculates the variance values ​​of the plurality of movement speeds; The analysis unit compares the variance value with the standard variance, and determines, according to the comparison result, that the volatility of the movement speed data of the print head exceeds a normal range, and the face sheet printer is in a first working state, or that the volatility of the movement speed data of the print head is within a normal range, and the face sheet printer is in a second working state; When the label printer is in the first working state, the analyzing unit controls the adjusting unit to reduce the rotation speeds of the conveying roller and the receiving roller according to the ratio of the standard deviation to the variance value, and reduces the initial detection period accordingly; 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 deviation to the variance value, and correspondingly increases the rotation speeds of the transmission roller and the receiving roller.

[0013] Furthermore, when the thermal face sheet is in the second stretched state, the analysis unit calculates an average pressure according to the conveying pressures of the two pressure rollers acquired by the detection component, and compares the average pressure with a critical value; The analysis unit determines whether the winding tension of the thermal sheet exceeds the tolerance range based on the comparison result of the average pressure and the critical value, whether the thermal sheet is at risk of being damaged or deformed and wrinkled, and determines the specific situation of adjusting the winding tension.

[0014] Furthermore, when the analysis unit determines that the winding tension of the thermal surface sheet is within the tolerance range, it draws a pressure change curve according to the average pressure and obtains the derivative function value of the pressure change curve; When the derivative function value is less than zero, the analyzing unit determines that the winding tension of the thermal surface sheet is decreasing after the winding tension is adjusted; When the derivative function value is greater than or equal to zero, the analysis unit determines that the winding tension of the thermal sheet remains unchanged or is increasing after the winding tension is adjusted, and the thermal sheet is jammed. The adjustment unit controls the indicator light to flash and send out a warning signal, and controls the equipment to stop urgently.

[0015] Furthermore, the integrated device also includes: The envelope loading box is a hollow structure used to place envelopes to be packaged; An envelope sending mechanism, which is connected to the envelope loading box and is used to send a plurality of envelopes to be packaged and used individually to the inner envelope waiting area; An envelope opening mechanism, connected to the envelope sending mechanism, for opening a single envelope in the envelope waiting area; A test paper loading mechanism, which is connected to the envelope opening mechanism and is used to perform double identification verification on the test paper and load it into the opened envelope after passing the verification; An envelope hinge mechanism, located on the side of the test paper loading mechanism, is used to tear off the offline paper on the envelope and seal the envelope hinge; A verification station, located on the side of the envelope hinge mechanism, for verifying the express number on the details sheet; A display, which is a data display of the integrated device, located on the top of the receiving box; A receiving box, located at the side of the verification station, for storing the packaged envelopes; A lifting mechanism, which is connected to the test paper loading mechanism and is used to transport the test paper to the test paper loading mechanism; A docking transition mechanism, which is connected to the lifting mechanism and is used to dock the test paper on the conveyor belt to the lifting elevator; A roller mechanism, which is located above the conveyor belt and is used to flatten the folded test paper; The conveying mechanism is used to connect the printed test paper to the conveyor belt and move the test paper through the conveyor belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are that the present invention is suitable for the needs of automatic packaging of test papers, and can realize the functions of confidential packaging, label printing, labeling, release paper recycling, etc. for test papers and mailing materials. Automated packaging equipment replaces manual packaging, which reduces the pressure of packaging work, improves work efficiency, and reduces the error rate; it has high integration, integrates test paper production and automatic mailing of test papers, has high operating efficiency, and the test paper production and packaging speed is ≧260 seals / hour, with high accuracy. The docking realizes full-process closed-loop precise printing, and realizes zero error in printing and packaging based on OCR and barcode dual recognition and verification technology; the present invention judges the stretching state of the thermal face sheet by the conveying pressure borne by several pressure rollers, avoids the thermal face sheet from being subjected to too high or too low winding tension, resulting in loosening or over-tension of the thermal face sheet, and increases the accuracy of the mailing information printing process.

[0017] Furthermore, as the thermal sheet is consumed, the angle between the thermal 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 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 determines the degree of consumption of the thermal sheet by the tangent angle, maintains a certain stretching state of the thermal 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 sheet, thereby increasing the accuracy and adaptability of judging the stretching state and avoiding inaccurate judgment that causes the thermal sheet to be in a poor stretching state for a long time.

[0018] Furthermore, in the application scenario of the present device, since the radius of the cylinder formed by the thermal face sheet 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 match. When the thermal face sheet is in an appropriately stretched state, the present invention determines whether the rotation speeds match by the linear speed difference between the conveying roller and the receiving roller, and correspondingly determines the cause of the rotation speed mismatch based on the increase ratio of the conveying roller and the decrease ratio of the receiving roller, thereby avoiding the stretching of the thermal face sheet or the loosening of the thermal face sheet due to linear speed mismatch, thereby affecting the printing process of the mailing information, and increasing the stability and accuracy of the equipment operation process.

[0019] Furthermore, the linear speed 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 the printing process. The print head needs to move quickly to ensure the continuity and clarity of the printed content. Therefore, when the thermal face sheet is thermally printed by the face sheet printer, the movement speed of the print head is affected by the movement speed of the thermal face sheet. The present invention reflects the working state of the printer through the volatility of the movement speed of the print head. When the volatility is large, the movement speed of the thermal face sheet is reduced to reduce the degree to which the movement speed of the print head is affected by the movement speed of the thermal face sheet, and the determination frequency of the working state of the printer and the stretching state of the thermal face sheet is increased, thereby increasing the monitoring intensity of the integrated equipment, more closely monitoring the printing and pasting process of the detailed face sheet, avoiding breakpoints or unclear situations during the printing process of the thermal face sheet, reducing the probability of inaccurate mailing information that may occur in the integrated equipment, and increasing the accuracy of the pasting of the oil seal information; at the same time, when the volatility is small, the maximum movement speed of the print head is determined under the premise of ensuring the volatility, matching the maximum rotation speed of the transmission roller and the receiving roller, and optimizing the printing efficiency of the face sheet printer.

[0020] Furthermore, the main function of the pressure roller is to ensure that the thermal paper can fit tightly to the print head during the printing process to avoid affecting the printing quality due to paper movement or wrinkling. When the thermal face sheet is in a tensioned state, the present invention judges the winding tension of the thermal face sheet according to the average speed of the pressure roller that bears the maximum conveying pressure, determines whether the winding tension causes the risk of damage to the thermal face sheet or the risk of deformation and wrinkling, issues a warning signal accordingly, and determines the specific circumstances of the winding tension adjustment according to the changing trend of the winding tension, thereby avoiding paper jams on the thermal face sheet and improving the adaptability of the equipment to risk judgment and the accuracy of adjusting equipment parameters.

[0027] The embodiment of the present invention provides an integrated device for printing, packaging and pasting information on a test paper, including: An envelope loading box 1, which is a hollow structure and is used to place envelopes to be packaged; An envelope sending mechanism 2, which is connected to the envelope loading box and is used to send a plurality of envelopes to be packaged and used individually to the envelope waiting area inside; An envelope opening mechanism 3, connected to the envelope sending mechanism, for opening a single envelope in the envelope waiting area; The test paper loading mechanism 4 is connected to the envelope opening mechanism and is used to perform OCR and barcode double recognition verification on the test paper, and put it into the opened envelope after passing the verification; An envelope hinge mechanism 5, which is located on the side of the test paper filling mechanism and is used to automatically tear off the offline paper on the envelope and seal the envelope hinge; The detailed sheet printing and pasting station 6 is located on the top of the envelope hinge mechanism, and includes a thermal sheet, a sheet printer 61, a transmission roller 62, a receiving roller 63 and a pressure roller 64, and is used to receive the mailing information of the test paper, print the detailed sheet and paste it on the envelope; Verification station 7, located on the side of the envelope hinge mechanism, is used to perform OCR photography verification on the express number on the details sheet; Display 8, which is a data display of the integrated device, is located on the top of the receiving box; A receiving box 9, which is located at the side of the verification station and is used to store the packaged envelopes; A lifting mechanism 10, which is connected to the test paper loading mechanism and is used to transport the test paper to the test paper loading mechanism; A docking transition mechanism 11, which is connected to the lifting mechanism and is used to dock the test paper on the conveyor belt to the lifting elevator; A roller mechanism 12, which is located above the conveyor belt and is used to flatten the folded test paper; A conveying mechanism 13, which is used to connect the printed test paper to a conveyor belt and move the test paper through the conveyor belt; A detection component connected to the detailed sheet printing and pasting station, used to obtain the conveying pressures and force angles of the pressure roller shafts according to the initial detection cycle, detect the rotation speeds of the conveying roller shaft and the receiving roller shaft, and store the moving speed of the print head; An analysis unit connected to the detection component, capable of determining a winding tension adjustment method according to the stretching state of the thermal sheet, or evaluating the degree of consumption of the thermal sheet according to the tangent angle to adjust the criterion for determining the stretching state, or determining whether the rotation speed matches and determining the cause of the mismatch according to the linear speed difference, or determining the rotation speed, the print head movement speed and the initial detection period according to the fluctuation of the print head movement speed and the working state of the sheet printer; an adjustment unit connected to the analysis unit and capable of adjusting the winding tension, rotation speed and print head movement speed of the device according to the parameters determined by the analysis unit; A print head is arranged inside the label printer.

[0028] In this embodiment, during the printing and pasting process of the detailed face sheet, the thermal face sheet is wound on the conveying roller in a cylindrical shape. The conveying roller outputs the thermal face sheet through two pressure rollers, enters the face sheet printer, and is printed by the print head. After printing, it is output through four pressure rollers to the receiving roller and wound into a cylindrical shape.

[0029] The detection component detects the conveying pressures borne by a plurality of pressure rollers according to the initial detection cycle, and the analysis unit compares any conveying pressure with a standard value, wherein 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; If any conveying pressure is less than the first standard value, the analyzing unit determines that the thermal surface sheet is in the first stretching state and the thermal surface sheet is loose, and controls the adjusting unit to adjust the winding tension; Specifically, the analysis unit increases the winding tension according to the ratio of the first standard value to the conveying pressure; 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 face sheet is in the third stretching state and the winding tension of the thermal face sheet is in an appropriate range; If any conveying pressure is greater than the second standard value, the analyzing unit determines that the thermal surface sheet is in the second stretching state, the thermal surface sheet is tensioned, and the adjusting unit is controlled to adjust the winding tension; 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; The standard value is a preset value set according to the material of the thermal sheet and the historical data of the conveying pressure borne by the pressure roller.

[0030] Specifically, the present invention is suitable for the demand of automatic packaging of test papers, and can realize functions such as confidential packaging, label printing, labeling, and release paper recycling of test papers and mailing materials. It replaces manual packaging with automated packaging equipment, reduces the pressure of packaging work, improves work efficiency, and reduces the error rate. It has high integration, integrates test paper production and automatic mailing of test papers, has high operating efficiency, and the test paper production and packaging speed is ≧260 seals / hour with high accuracy. It can achieve full-process closed-loop precise printing through docking, and realizes zero error in printing and packaging based on OCR and barcode dual recognition and verification technology. The present invention judges the stretching state of the thermal face sheet through the conveying pressure borne by several pressure rollers, so as to avoid the thermal face sheet being subjected to too high or too low winding tension, which may cause the thermal face sheet to become loose or over-tensioned, thereby increasing the accuracy of the mailing information printing process.

[0031] 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.

[0032] 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; 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; 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; Specifically, the analysis unit reduces the first standard value according to the ratio of the fixed angle to the tangent angle; The fixed angle can be set according to the tangent angle when the device is installed into the thermal surface monotube and specific needs.

[0033] 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.

[0034] 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.

[0035] 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; 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 rotation speeds of the transmission roller and the receiving roller match; If the absolute value of the linear speed difference is greater than the difference evaluation value, the analyzing unit determines that the rotation speeds of the conveying roller and the receiving roller do not match, controls the adjusting unit to adjust the rotation speeds of the conveying roller and the receiving roller, and determines the cause of the rotation speed mismatch; Specifically, if the speed of the transmission roller axis is greater than the speed of the receiving roller axis, the analysis unit controls the adjustment unit to increase the speed of the receiving roller axis according to the absolute value of the linear speed difference; If the axis speed of the conveying roller is lower than the axis speed of the receiving roller, the analyzing unit controls the regulating unit to increase the rotation speed of the conveying roller according to the absolute value of the linear velocity difference.

[0036] The detection component detects and records the rotation speeds of the transmission roller and the receiving roller in real time, and the analysis unit calculates the increase ratio of the transmission roller rotation speed and the decrease ratio of the receiving roller rotation speed according to the initial detection cycle. If the speed increase ratio is not equal to the speed decrease ratio, the analysis unit determines that the reason why the speeds of the conveying roller and the receiving roller do not match is that the speed increase ratio does not match the speed decrease ratio.

[0037] Specifically, in the application scenario of the present device, since the radius of the cylinder formed by the thermal face sheet 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 match. When the thermal face sheet is in an appropriately stretched state, the present invention determines whether the rotation speeds match by the linear speed difference between the conveying roller and the receiving roller, and correspondingly determines the cause of the rotation speed mismatch based on the increase ratio of the conveying roller and the decrease ratio of the receiving roller, thereby avoiding the stretching of the thermal face sheet or the loosening of the thermal face sheet due to linear speed mismatch, thereby affecting the printing process of the mailing information, and increasing the stability and accuracy of the equipment operation process.

[0038] In this embodiment, the print head is the core component of the label printer, responsible for printing text or patterns on thermal paper. Its working principle is to heat the coating of thermal paper through a heating element (such as a semiconductor) to cause a chemical reaction in the coating to form a visible pattern or text. The print head prints the information on the paper in the form of a dot matrix by precisely controlling the position and temperature of the heating point.

[0039] When the thermal sheet is in the third stretching state and the speeds of the transmission roller and the receiving roller match, 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 in the initial detection cycle and calculates the variance values ​​of the several moving speeds; If the variance value is greater than the standard variance, the analysis unit determines that the volatility of the movement speed data of the print head exceeds the normal range, and the label printer is in the first working state; 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 a normal range, and the label printer is in the second working state; When the label printer is in the first working state, the analysis unit controls the adjustment unit to reduce the rotation speeds of the transmission roller and the receiving roller according to the ratio of the standard deviation to the variance value, and reduces the initial detection period accordingly; When the sheet 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 deviation to the variance value, and correspondingly increases the rotation speeds of the transmission roller and the receiving roller.

[0040] The standard deviation is a preset value set according to the printing parameters of the label printer and the printing requirements of the oil seal information.

[0041] Specifically, the linear speed 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 the printing process. The print head needs to move quickly to ensure the continuity and clarity of the printed content. Therefore, when the thermal face sheet is thermally printed by the face sheet printer, the movement speed of the print head is affected by the movement speed of the thermal face sheet. The present invention reflects the working state of the printer through the volatility of the movement speed of the print head. When the volatility is large, the movement speed of the thermal face sheet is reduced to reduce the degree to which the movement speed of the print head is affected by the movement speed of the thermal face sheet, and the determination frequency of the working state of the printer and the stretching state of the thermal face sheet is increased, thereby increasing the monitoring intensity of the integrated equipment, more closely monitoring the printing and pasting process of the detailed face sheet, avoiding breakpoints or unclear situations during the printing process of the thermal face sheet, reducing the probability of inaccurate mailing information that may occur in the integrated equipment, and increasing the accuracy of the pasting of the oil seal information; at the same time, when the volatility is small, the maximum movement speed of the print head is determined under the premise of volatility, matching the maximum rotation speed of the transmission roller and the receiving roller, and optimizing the printing efficiency of the face sheet printer.

[0042] In this embodiment, two pressure rollers bear a greater pressure than other pressure rollers in the tensioned state. When the thermal sheet is in the second tensioned state, the detection component detects the conveying pressure of the two pressure rollers, and the analysis unit calculates the average pressure. If the average pressure is greater than the critical value, the analysis unit determines that the winding tension of the thermal sheet exceeds the tolerance range and the thermal sheet is at risk of being damaged, and controls the adjustment unit to control the indicator light to flash and send out an alarm signal, and controls the equipment to stop urgently; If the average pressure is less than the critical value, the analysis unit determines that the winding tension of the thermal sheet is within the tolerance range, and the thermal sheet has the risk of deformation and wrinkling, and determines the specific situation of the winding tension adjustment; The critical value is a preset value set according to the material of the thermal label.

[0043] When the winding tension of the thermal face sheet is within the tolerance range, the analysis unit draws a pressure change curve of the average pressure. If the derivative function value is less than zero, the analysis unit determines that the winding tension of the thermal surface sheet is gradually decreasing after adjusting the winding tension; If the derivative function value is greater than or equal to zero, the analysis unit determines that the winding tension of the thermal sheet remains unchanged or is gradually increasing after adjusting the winding tension, and the thermal sheet is jammed. The adjustment unit controls the indicator light to flash and send out a warning signal, and the control equipment stops suddenly.

[0044] Specifically, the main function of the pressure roller is to ensure that the thermal paper can fit tightly to the print head during the printing process to avoid affecting the printing quality due to paper movement or wrinkling.
