Description

Technical Field

[0001] The invention relates to the technical field of publication gluing, in particular to a gluing device for publication printing. Background Art

[0002] In the prior art, publications refer to printed materials with a certain material form for the purpose of storing and disseminating knowledge and information. A gluing device is required in the printing of publications, but the current gluing device has the problem of uneven glue coating, which causes the inner pages of the publication to easily fall off and the bonding to be loose.

[0003] Chinese Patent Publication No.: CN106004150A discloses a gluing machine, including a base, a cleaning device, a gluing device, and a host computer. The base includes a base, a stepper motor, and a conveyor belt. The stepper motor is connected to the conveyor belt to control the conveying speed of the conveyor belt. The cleaning device and the gluing device are connected to the base in sequence. The cleaning device includes a cleaning chamber, an exhaust fan, a drive motor, and a rolling brush located in the cleaning chamber. The exhaust fan is provided with a pipeline connected to the top of the cleaning chamber. The rolling brush is connected to the drive motor and is used for surface cleaning of printed materials. The gluing device includes a gluing chamber, an extruder, and a composite roller group. The extruder is located above the gluing chamber, and the outlet of the extruder corresponds to the composite roller group. It can be seen that the gluing machine has the problem that part of the glue solidifies in the glue delivery pipeline, causing the delivery pipeline to be blocked, thereby causing insufficient glue coating thickness, and part of the hydraulic oil leaks from the connection, resulting in insufficient clamping force of the clamping plate when clamping bulk publications, thereby causing the stability and accuracy of the gluing process to decrease. Summary of the invention

[0004] To this end, the present invention provides a gluing device for publication printing, which is used to overcome the problems in the prior art that part of the glue solidifies in the glue delivery pipeline, causing the delivery pipeline to be blocked, thereby resulting in insufficient glue coating thickness and part of the hydraulic oil leaking from the connection, resulting in insufficient clamping force of the clamping plate when clamping bulk publications, thereby causing a decrease in the stability and accuracy of the gluing process.

[0005] To achieve the above-mentioned purpose, the present invention provides a gluing device for publication printing, comprising: a conveying module, used to convey bulk publications to an area to be glued, comprising a clamping assembly for clamping the bulk publications and a moving assembly connected to the clamping assembly for changing the horizontal position of the clamping assembly; a gluing module, which is connected to the conveying module, comprising a cutting assembly arranged below the clamping assembly for cutting the bulk publications to output the publications to be glued and a gluing assembly connected to the cutting assembly for applying glue to the publications to be glued to output the inner page glued publications; a drying module, which is connected to the gluing module for sequentially performing cover glue binding and wind binding on the inner page glued publications Drying operation to output finished publications; a control module, which is respectively connected to the conveying module, the gluing module and the drying module, and is used to determine the corresponding working mode of the gluing component according to the variance of the thickness of the glue-bound side of the same finished publication, or, to determine the corresponding operating mode of the clamping component according to the variance of the thickness of the glue-bound side of the same finished publication and the protruding area of ​​the pages of the non-glue-bound edge of the finished publication, and, to determine the first corresponding air-drying height according to the protruding area of ​​the pages of the non-glue-bound edge of the finished publication and the average hardness of the glue-bound edge of the finished publication, and, to determine the second corresponding air-drying height according to the temperature rise rate of the cover glue-bound area; wherein, the first corresponding air-drying height is greater than the second corresponding air-drying height.

[0006] Furthermore, the clamping assembly comprises:

[0007] A control valve for adjusting the clamping pressure by changing the hydraulic delivery flow;

[0008] A hydraulic delivery pipeline connected to the control valve for delivering hydraulic oil to a position for clamping bulk publications;

[0009] A hydraulic oil tank connected to the hydraulic delivery pipeline and used to store hydraulic oil;

[0010] A hydraulic cylinder connected to the hydraulic delivery pipeline to provide clamping pressure;

[0011] A clamping plate is connected to the hydraulic cylinder and is used for clamping bulk publications.

[0012] Furthermore, the control module obtains the thickness of the binding side of a plurality of identical finished publications, and calculates the variance of the thickness of the binding side of the identical finished publications.

[0013] If the variance of the thickness of the binding side of the same finished publication is greater than the preset second variance, the control module controls the gluing component to apply glue to the binding publication in the corresponding working mode.

[0014] Furthermore, the corresponding working mode is that the gluing component applies glue to the publication to be bound at a corresponding supply speed, and the corresponding supply speed is determined by the difference between the variance of the thickness of the binding side of the same finished publication and a preset second variance.

[0015] Further, if the variance of the thickness of the perfect-bound side of the same finished publication is greater than the preset first variance and less than or equal to the preset second variance, the control module obtains the protruding area of ​​the page of the non-perfect-bound edge of the finished publication,

[0016] If the protruding area of ​​the pages of the non-binding edge of the finished publication is greater than the preset first area and less than or equal to the preset second area, the control module controls the clamping assembly to clamp the bulk publication in the corresponding operation mode.

[0017] Furthermore, the corresponding operation mode is that the clamping assembly clamps the bulk publication at a corresponding conveying rate, and the corresponding conveying rate is determined by the difference between the protruding area of ​​the pages of the non-binding edge of the finished publication and a preset first area.

[0018] Furthermore, if the protruding area of ​​the book pages of the non-binding edge of the finished publication is greater than the preset second area, the control module obtains the hardness of several sampling points of the binding edge of the finished publication, and calculates the average hardness of the binding edge of the finished publication.

[0019] If the average hardness of the edge of the finished publication binding is less than the preset hardness, the control module controls the drying module to air-dry the glue of the finished publication at the first corresponding air-drying height.

[0020] Furthermore, the first working mode is that the first corresponding air-drying height is determined by the difference between a preset hardness and an average hardness of the edge of the finished publication binding.

[0021] Furthermore, the control module obtains the temperature of the cover binding area in a single cycle under the condition that the drying module air-dries the glue liquid of the finished publication at the first corresponding air-drying height, and calculates the temperature increase rate of the cover binding area.

[0022] If the temperature increase rate of the cover binding area is greater than the preset increase rate, the control module controls the drying module to air-dry the glue of the finished publication at the second corresponding air-drying height.

[0023] Furthermore, the second corresponding air-drying height is determined by the difference between the temperature increase rate of the cover binding area and a preset increase rate.

[0024] Compared with the prior art, the beneficial effect of the present invention lies in that the device of the present invention adjusts the supply speed of the glue according to the variance of the thickness of the glue-bound side of the same finished publication by setting a conveying module, a gluing module, a drying module and a control module, thereby reducing the influence of part of the glue solidifying in the pipeline for conveying the glue due to the inability of all the glue to flow back into the glue storage tank after each operation of the device, resulting in partial blockage of the pipeline, and then resulting in insufficient coating thickness during the process of coating the glue on the finished publication, resulting in a decrease in the accuracy of the gluing process. By adjusting the hydraulic conveying rate during clamping according to the protruding area of ​​the pages at the non-binding edge of the finished publication, the aging of the material at the connection between the hydraulic conveying pipeline and the hydraulic cylinder is reduced. , causing part of the hydraulic oil to leak from the connection, resulting in insufficient clamping force of the clamping plate when clamping bulk publications, causing the stability of the gluing process to decrease. By adjusting the first corresponding air-drying height according to the average hardness of the edge of the finished publication binding, the influence of the reduced drying effect and the reduced accuracy of the gluing process caused by the thinning of the heating wire in the hot air blower due to long-term use is reduced. By adjusting the second corresponding air-drying height according to the temperature rise rate of the cover binding area, the influence of the excessively high vertical height of the hot air blower, which causes the temperature of the cover placement platform to rise too quickly, thereby causing the glue to be dried too quickly and causing the stability of the gluing process to decrease is reduced, thereby achieving improvement in the stability and accuracy of the gluing process.

[0025] Furthermore, the device of the present invention adjusts the supply speed of the glue solution by setting the difference between the variance of the thickness of the glue-bound side of the same finished publication and a preset second variance, thereby reducing the effect of part of the glue solution solidifying in the pipeline for conveying the glue solution, causing partial blockage of the pipeline, and further resulting in insufficient coating thickness during the process of coating the finished publication with glue, resulting in a decrease in the accuracy of the gluing process, thereby further improving the stability and accuracy of the gluing process.

[0026] Furthermore, the device of the present invention adjusts the hydraulic delivery rate during clamping by setting the difference between the protruding area of ​​the pages of the non-glued edge of the finished publication and the preset first area, thereby reducing the impact of aging of the material at the connection between the hydraulic delivery pipeline and the hydraulic cylinder, which causes part of the hydraulic oil to leak from the connection, resulting in insufficient clamping force of the clamping plate when clamping bulk publications, and causing a decrease in the stability of the gluing process, thereby further improving the stability and accuracy of the gluing process.

[0027] Furthermore, the device of the present invention adjusts the first corresponding air-drying height by setting the difference between a preset hardness and the average hardness of the edge of the finished publication binding, thereby reducing the impact of the accuracy of the gluing process caused by the heating wire in the hot air blower becoming thinner due to long-term use, thereby reducing the drying effect, thereby reducing the impact, and further improving the stability and accuracy of the gluing process.

[0028] Furthermore, the device of the present invention adjusts the second corresponding air-drying height by setting the difference between the temperature rise rate of the cover binding area and the preset rise rate, thereby reducing the impact of the vertical height of the hot air blower being too high, which causes the temperature of the cover placement platform to rise too quickly, thereby causing the glue to dry too quickly and causing the stability of the gluing process to decrease, thereby further improving the stability and accuracy of the gluing process.

[0043] Wherein, the first corresponding air-drying height is greater than the second corresponding air-drying height.

[0044] Specifically, the variance of the thickness of the glue-bound side of the same finished publication is the variance of the thickness of the glue-bound side of several same finished publications. The calculation method of the variance of the thickness of the glue-bound side of the same finished publication is a conventional technical means well known to those skilled in the art. Therefore, the calculation process of the variance of the thickness of the glue-bound side of the same finished publication will not be repeated here.

[0045] Specifically, the average hardness of the edge of the finished publication binding is calculated as follows:

[0047] Where Z is the average hardness of the edge of the finished publication binding, X a is the hardness of the ath sampling point on the edge of the finished publication binding, n is the number of sampling points, and n is a natural number greater than or equal to 1.

[0048] Specifically, the temperature rise rate of the cover binding area is calculated as follows:

[0049]

[0050] Wherein, G is the temperature increase rate of the cover binding area, K1 is the temperature of the cover placement platform 13 at the initial moment of a single cycle, K2 is the temperature of the cover placement platform 13 at the end moment of a single cycle, and T is the duration of a single cycle.

[0051] Specifically, the publications to be bound refer to the bulk publications that have been subjected to a cutting operation on the binding side thereof but have not yet been subjected to a glue coating operation.

[0052] Specifically, the inner page binding publication refers to the publication to be bound after the glue liquid coating operation has been performed on the publication to be bound but the cover has not yet been bound.

[0053] Specifically, the protruding area of ​​the pages at the non-binding edge of the finished publication means the total area of ​​the pages that fall off from the three sides of the finished publication that are not bound and exceed the edge area of ​​the finished publication.

[0054] Specifically, the mobile components include:

[0055] A slide rail 7, which is arranged below the clamping plate 4 and is used to define a moving path of the clamping plate 4;

[0056] The slide rail motor 14 is connected to the slide rail 7 to provide power for the clamping plate 4 to move.

[0057] Specifically, the cutting components include:

[0058] A milling cutter 6, which is arranged below the clamping plate 4 and is used to cut the binding side of the bulk publications;

[0059] A transmission shaft 24, which is connected to the milling cutter 6 and is used to transmit cutting power to the milling cutter 6;

[0060] The electric motor 23 is connected to the transmission shaft 24 to provide cutting power.

[0061] Specifically, the gluing components include:

[0062] A side glue wheel 8, which is arranged above the electric motor 23 and is used to apply glue to the side of the spine of the publication to be bound;

[0063] A glue storage tank 20, which is arranged below the side rubber wheel 8 and is used to store glue;

[0064] A glue delivery pipeline 22, which is connected to the glue storage tank 20 and is used to deliver glue;

[0065] A glue extraction pump 21, which is connected to the glue delivery pipeline 22, and is used to provide a delivery power for the glue;

[0066] A main glue wheel 9, which is arranged above the glue storage tank 20 and is used to apply glue to the binding side of the publication to be bound;

[0067] The scraper 10 is arranged above the glue storage tank 20 to scrape off the excess glue of the publication to be bound.

[0068] Specifically, the drying module includes:

[0069] A hot air blower 18, which is arranged below the control valve 1, to provide drying wind;

[0070] A cover placement platform 13, which is arranged above the hot air blower 18 and is used to place the finished publication cover;

[0073] Specifically, the gluing device for publication printing also includes:

[0075] A visual sensor 11, which is arranged above the cover placement platform 13, and is used to detect the protruding area of ​​the pages of the non-binding edge of the finished publication;

[0077] The hardness tester 16 is arranged above the hot air blower 18 and is used to detect the hardness of the edge of the finished publication binding.

[0078] Specifically, in the structural diagram of the present invention, the dotted line structure is arranged inside the gluing device, and the solid line structure is arranged on the surface of the device.

[0079] Specifically, the cover binding area means an area on the cover placement platform where the cover is bound.

[0080] It can be understood by those skilled in the art that the power providing mechanism of the clamping plate 4 provided in the present invention is a preferred embodiment. Under the premise of not affecting the movement trajectory of the clamping plate 4, the power providing mode of the control valve 1, the hydraulic delivery pipeline 3, the hydraulic oil tank 2 and the hydraulic cylinder 5 can be adaptively adjusted within the basic framework.

[0081] In practice, the device of the present invention is provided with a conveying module, a gluing module, a drying module and a control module, and the supply speed of the glue is adjusted according to the variance of the thickness of the glue-bound side of the same finished publication, thereby reducing the influence of the glue being unable to flow back to the glue storage tank 20 after each operation of the device, resulting in part of the glue solidifying in the pipeline for conveying the glue, causing partial blockage of the pipeline, and then resulting in insufficient coating thickness during the process of coating the glue on the finished publication, resulting in reduced accuracy of the gluing process. By adjusting the hydraulic conveying rate during clamping according to the protruding area of ​​the pages at the non-glue-bound edge of the finished publication, the aging of the material at the connection between the hydraulic conveying pipeline 3 and the hydraulic cylinder 5, resulting in partial hydraulic blockage, is reduced. Oil leaks from the connection, resulting in insufficient clamping force of the clamping plate 4 when clamping bulk publications, which causes a decrease in the stability of the gluing process. By adjusting the first corresponding air-drying height according to the average hardness of the edge of the finished publication binding, the influence of the reduced drying effect and the reduced accuracy of the gluing process caused by the thinning of the heating wire in the hot air blower 18 due to long-term use is reduced. By adjusting the second corresponding air-drying height according to the temperature rise rate of the cover binding area, the influence of the excessive vertical height of the hot air blower, which causes the temperature of the cover placing platform 13 to rise too quickly, thereby causing the glue to be dried too quickly and causing a decrease in the stability of the gluing process is reduced, thereby achieving improvement in the stability and accuracy of the gluing process.

[0082] Specifically, the clamping assembly comprises:

[0083] A control valve 1, for adjusting the clamping pressure by changing the hydraulic delivery flow;

[0084] A hydraulic delivery pipeline 3, which is connected to the control valve 1 and is used to deliver hydraulic oil to the position for clamping bulk publications;

[0085] A hydraulic oil tank 2, which is connected to the hydraulic delivery pipeline 3 and is used to store hydraulic oil;

[0086] A hydraulic cylinder 5 connected to the hydraulic delivery pipeline 3 to provide clamping pressure;

[0087] The clamping plate 4 is connected to the hydraulic cylinder 5 and is used for clamping bulk publications.

[0088] Specifically, the hydraulic cylinder 5 includes a piston rod, and the opening and closing of the clamping plate 4 are controlled by the movement of the piston rod.

[0089] Specifically, the control module obtains the thickness of the binding side of a plurality of identical finished publications, and calculates the variance of the thickness of the binding side of the identical finished publications.

[0090] If the thickness of the binding side of the same finished publication is greater than a preset first variance, the control module determines that the stability of the gluing process is lower than an allowable range;

[0091] If the thickness of the binding side of the same finished publication is greater than the preset first variance and less than or equal to the preset second variance, the control module preliminarily determines that the validity of the binding of the finished publication is lower than the allowable range, and performs a secondary determination on the validity of the binding of the finished publication based on the protruding area of ​​the pages of the non-binding edge of the finished publication;

[0092] If the variance of the thickness of the binding side of the same finished publication is greater than the preset second variance, the control module controls the gluing component to apply glue to the binding publication in the corresponding working mode.

[0093] Optionally, the preferred embodiment of the preset first variance Q1 is Q1=1.5 cm 2 The preferred embodiment of the preset second variance Q2 is Q2=2cm 2 .

[0094] Specifically, the variance of the thickness of the same finished publication on the binding side is recorded as Q, and the difference between the variance of the thickness of the same finished publication on the binding side and the preset second variance is recorded as ΔQ, and ΔQ=Q-Q2 is set.

[0095] In implementation, the device of the present invention determines the stability of the gluing process by setting a preset first variance and a preset second variance, thereby reducing the impact of the reduced accuracy of the gluing process due to inaccurate judgment of the stability of the gluing process, and further improving the stability and accuracy of the gluing process.

[0096] Specifically, the corresponding working mode is that the gluing component applies glue to the publication to be bound at a corresponding supply speed, and the corresponding supply speed is determined by the difference between the thickness variance of the binding side of the same finished publication and a preset second variance.

[0097] Specifically, the specific process of determining the corresponding feeding speed by the difference between the variance of the thickness of the perfect binding side of the same finished publication and the preset second variance is as follows:

[0098] The control module adjusts the supply speed of the glue solution to the first supply speed using a preset first supply speed adjustment coefficient under a preset first variance difference condition; the preset first variance difference condition is that the difference between the variance of the thickness of the binding side of the same finished publication and the preset second variance is less than or equal to the preset variance difference;

[0099] The control module adjusts the supply speed of the glue solution to the second supply speed using a preset second supply speed adjustment coefficient under a preset second variance difference condition; the preset second variance difference condition is that the difference between the variance of the thickness of the binding side of the same finished publication and the preset second variance is greater than the preset variance difference;

[0100] Wherein, the preset first supply speed adjustment coefficient is smaller than the preset second supply speed adjustment coefficient.

[0101] Specifically, the corresponding supply speed includes a first supply speed and a preset second supply speed.

[0102] Specifically, the preset variance difference is recorded as △Q0, and △Q0=0.5cm 2 The preset first supply speed adjustment coefficient is denoted as α1, and α1 is set to 1.2. The preset second supply speed adjustment coefficient is denoted as α2, and α2 is set to 1.4. The supply speed of the glue is denoted as V, wherein 1<α1<α2. The corresponding supply speed is denoted as V', and V' is set to V×(1+αi) / 2, wherein αi is the preset i-th supply speed adjustment coefficient, and i is set to 1, 2.

[0103] In practice, the device of the present invention adjusts the supply speed of the glue solution by setting the difference between the variance of the thickness of the glue-bound side of the same finished publication and the preset second variance, thereby reducing the effect of part of the glue solution solidifying in the pipeline for conveying the glue solution, resulting in partial blockage of the pipeline, and further resulting in insufficient coating thickness during the process of coating the finished publication with glue, causing a decrease in the accuracy of the gluing process, thereby further improving the stability and accuracy of the gluing process.

[0104] Specifically, if the variance of the thickness of the perfect-bound side of the same finished publication is greater than the preset first variance and less than or equal to the preset second variance, the control module obtains the protruding area of ​​the page of the non-perfect-bound edge of the finished publication,

[0105] If the protruding area of ​​the pages of the non-binding edge of the finished publication is greater than the preset first area, the control module secondly determines that the validity of the binding of the finished publication is lower than the allowable range;

[0106] If the protruding area of ​​the pages of the non-binding edge of the finished publication is greater than the preset first area and less than or equal to the preset second area, the control module controls the clamping assembly to clamp the bulk publication in the corresponding operation mode;

[0107] If the protruding area of ​​the pages of the non-binding edge of the finished publication is greater than the preset second area, the control module preliminarily determines that the operating stability of the hot air blower 18 is lower than the allowable range, and makes a secondary determination on the operating stability of the hot air blower 18 based on the average hardness of the binding edge of the finished publication.

[0108] Optionally, the preferred embodiment of the preset first area P1 is P1=1 cm 2 The preferred embodiment of the preset second area P2 is P2 = 2 cm 2 .

[0109] Specifically, the protruding area of ​​the page of the non-binding edge of the finished publication is recorded as P, and the difference between the protruding area of ​​the page of the non-binding edge of the finished publication and the preset first area is recorded as ΔP, and ΔP=P-P1 is set.

[0110] In implementation, the device of the present invention performs a secondary judgment on the effectiveness of the binding of the finished publication by setting a preset first area and a preset second area, thereby reducing the impact of the stability of the gluing process caused by inaccurate secondary judgment on the effectiveness of the binding of the finished publication, and further improving the stability and accuracy of the gluing process.

[0111] Specifically, the corresponding operation mode is that the clamping assembly clamps the bulk publication at a corresponding conveying rate, and the corresponding conveying rate is determined by the difference between the protruding area of ​​the pages of the non-binding edge of the finished publication and a preset first area.

[0112] Specifically, the specific process of determining the corresponding conveying rate by the difference between the protruding area of ​​the book page of the non-binding edge of the finished publication and the preset first area is as follows:

[0113] The control module adjusts the hydraulic conveying rate during clamping to the first conveying rate using a preset first conveying rate adjustment coefficient under a preset first area difference condition; the preset first area difference condition is that the difference between the protruding area of ​​the pages of the non-binding edge of the finished publication and the preset first area is less than or equal to the preset area difference;

[0114] The control module adjusts the hydraulic conveying rate during clamping to a second conveying rate using a preset second conveying rate adjustment coefficient under a preset second area difference condition; the preset second area difference condition is that the difference between the protruding area of ​​the page of the non-binding edge of the finished publication and the preset first area is greater than the preset area difference;

[0115] Wherein, the preset first delivery rate adjustment coefficient is smaller than the preset second delivery rate adjustment coefficient.

[0116] Specifically, the corresponding delivery rates include a first delivery rate and a second delivery rate.

[0117] Specifically, the preset area difference is recorded as △P0, and △P0=0.5cm 2 The preset first conveying rate adjustment coefficient is recorded as β1, and β1 is set to 1.1. The preset second conveying rate adjustment coefficient is recorded as β2, and β2 is set to 1.3. The hydraulic conveying rate during clamping is recorded as H, where 1<β1<β2. The corresponding conveying rate is recorded as H', and H' is set to H×(1+2βj) / 3, where βj is the preset j-th conveying rate adjustment coefficient, and j is set to 1, 2.

[0118] The device of the present invention adjusts the hydraulic delivery rate during clamping by setting the difference between the protruding area of ​​the pages of the non-binding edge of the finished publication and the preset first area, thereby reducing the impact of aging of the material at the connection between the hydraulic delivery pipeline 3 and the hydraulic cylinder 5, which causes part of the hydraulic oil to leak from the connection, resulting in insufficient clamping force of the clamping plate 4 when clamping bulk publications, thereby reducing the stability of the gluing process. This further improves the stability and accuracy of the gluing process.

[0119] Specifically, if the protruding area of ​​the book page of the non-binding edge of the finished publication is greater than the preset second area, the control module obtains the hardness of several sampling points of the binding edge of the finished publication, and calculates the average hardness of the binding edge of the finished publication.

[0120] If the average hardness of the edge of the finished publication is less than the preset hardness, the control module determines for the second time that the operating stability of the hot air blower 18 is below the allowable range, and controls the drying module to air-dry the glue of the finished publication at the first corresponding air-drying height.

[0121] Optionally, a preferred embodiment of the preset hardness Y0 is Y0=30 Shore A.

[0122] Specifically, the average hardness of the edge of the finished publication is recorded as Y, the difference between the preset hardness and the average hardness of the edge of the finished publication is recorded as △Y, and △Y=Y0-Y is set.

[0123] In practice, the device of the present invention performs a secondary judgment on the operating stability of the hot air blower 18 by setting a preset hardness, thereby reducing the impact of the reduced accuracy of the gluing process due to inaccurate secondary judgment on the operating stability of the hot air blower 18, and further improving the stability and accuracy of the gluing process.

[0124] Specifically, the first corresponding air-drying height is determined by the difference between the preset hardness and the average hardness of the edge of the finished publication binding.

[0125] Specifically, the specific process of determining the first corresponding air-drying height by the difference between the preset hardness and the average hardness of the edge of the finished publication binding is as follows:

[0126] The control module adjusts the vertical height of the hot air blower to the first air-drying height using a preset first air-drying height adjustment coefficient under a preset first hardness difference condition; the preset first hardness difference condition is that the difference between the preset hardness and the average hardness of the edge of the finished publication binding is less than or equal to the preset hardness difference;

[0127] The control module adjusts the vertical height of the hot air blower to the second air-drying height using a preset second air-drying height adjustment coefficient under a preset second hardness difference condition; the preset second hardness difference condition is that the difference between the preset hardness and the average hardness of the edge of the finished publication binding is greater than the preset hardness difference;

[0128] Wherein, the preset first air-drying height adjustment coefficient is smaller than the preset second air-drying height adjustment coefficient.

[0129] Specifically, the first corresponding air-drying height includes a first air-drying height and a second air-drying height.

[0130] Specifically, the preset hardness difference is recorded as △Y0, and △Y0 is set to 5Shore A. The preset first air-drying height adjustment coefficient is recorded as γ1, and γ1 is set to 1.15. The preset second air-drying height adjustment coefficient is recorded as γ2, and γ2 is set to 1.25. The vertical height of the hot air blower is recorded as L, wherein 1<γ1<γ2. The first corresponding air-drying height is recorded as L', and L'=L×(1+3γm) / 4, wherein γm is the preset mth air-drying height adjustment coefficient, and m=1,2.

[0131] The device of the present invention adjusts the first corresponding air-drying height by setting the difference between the preset hardness and the average hardness of the edge of the finished publication binding, thereby reducing the influence of the electric heating wire in the hot air blower 18 becoming thinner due to long-term use, thereby reducing the drying effect and causing the accuracy of the gluing process to decrease, and further improving the stability and accuracy of the gluing process.

[0132] Specifically, the control module obtains the temperature of the cover binding area in a single cycle under the condition that the drying module air-dries the glue liquid of the finished publication at the first corresponding air-drying height, and calculates the temperature increase rate of the cover binding area.

[0133] If the temperature increase rate of the cover binding area is greater than the preset increase rate, the control module determines that the environmental stability of the cover binding process is lower than the allowable range, and controls the drying module to air-dry the glue of the finished publication at the second corresponding air-drying height.

[0134] Optionally, a preferred embodiment of the preset increase rate R0 is R0=3°C / h.

[0135] Specifically, the temperature increase rate of the cover binding area is recorded as R, and the difference between the temperature increase rate of the cover binding area and the preset increase rate is recorded as ΔR, and ΔR=R-R0 is set.

[0136] The device of the present invention determines the environmental stability of the cover binding process by setting a preset rising rate, thereby reducing the impact of the stability of the gluing process caused by inaccurate judgment of the environmental stability of the cover binding process, and further improving the stability and accuracy of the gluing process.

[0137] Specifically, the second corresponding air-drying height is determined by the difference between the temperature increase rate of the cover binding area and a preset increase rate.

[0138] Specifically, the specific process of determining the second corresponding air-drying height by the difference between the temperature increase rate of the cover binding area and the preset increase rate is as follows:

[0139] The control module uses a preset fourth air-drying height adjustment coefficient to adjust the first corresponding air-drying height to a third air-drying height under a preset first increase rate difference condition; the preset first increase rate difference condition is that the difference between the temperature increase rate of the cover binding area and the preset increase rate is less than or equal to the preset increase rate difference;

[0140] The control module uses a preset third air-drying height adjustment coefficient to adjust the first corresponding air-drying height to a fourth air-drying height under a preset second increase rate difference condition; the preset second increase rate difference condition is that the difference between the temperature increase rate of the cover binding area and the preset increase rate is greater than the preset increase rate difference;

[0141] Among them, the preset third air-drying height adjustment coefficient is smaller than the preset fourth air-drying height adjustment coefficient.

[0142] Specifically, the second corresponding air-drying height includes a third air-drying height and a fourth air-drying height.

[0143] Specifically, the preset rising rate difference is recorded as △R0, and △R0 is set to 0.5℃ / h. The preset third air-drying height adjustment coefficient is recorded as γ3, and γ3 is set to 0.8. The preset fourth air-drying height adjustment coefficient is recorded as γ4, and γ4 is set to 0.9, wherein 0<γ3<γ4<1. The second corresponding air-drying height is recorded as L", and L" is set to L'×(1+3γw) / 4, wherein γw is the preset wth air-drying height adjustment coefficient, and w is set to 3, 4.

[0144] The device of the present invention adjusts the second corresponding air-drying height by setting the difference between the temperature rise rate of the cover binding area and the preset rise rate, thereby reducing the impact of the vertical height of the hot air blower being too high, which causes the temperature of the cover placement platform 13 to rise too quickly, thereby causing the glue to dry too quickly and causing the stability of the gluing process to decrease, and further improves the stability and accuracy of the gluing process.

[0147] In this embodiment 1, ΔQ=3 μm 2 The control module determines that △Q>△Q0 and uses the preset first supply speed adjustment coefficient to adjust the supply speed of the glue solution to the second supply speed, and calculates that V'=20mL / min×(1+1.2) / 2=22mL / min.
