[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] Figure 1 The structure of the book gluing and drying system 100 according to some embodiments of the present invention is shown below, in conjunction with... Figure 1 The book gluing and drying system 100 is described.
[0032] In this embodiment, the book drying system 100 is used to dry the glue applied to the inner pages of a book. The book is, for example, a already bound book, where glue is applied between the inner pages and then pasted. The book is, for example, a block book.
[0033] See Figure 1 The book gluing and drying system 100 includes a drying device 110 and a cooling device 120. The drying device 110 dries the books, reducing their moisture content and mitigating the risk of page deformation due to water absorption. The cooling device 120 cools the dried books to facilitate storage and reduce line occupancy, thus improving efficiency. In some embodiments, the drying device 110 and cooling device 120 are linearly arranged, with the cooling device 120 positioned downstream of the drying device 110 in the direction of movement of the first conveyor belt 111. After drying, the cooling device 120 rapidly lowers the book temperature, allowing for efficient storage and preventing fire hazards caused by residual heat from drying.
[0034] like Figure 1 As shown, the drying device 110 includes a first conveyor belt 111, a drying chamber 112, and a circulation device 113. Books can move along the first conveyor belt 111. For example... Figure 1 As shown, the first conveyor belt 111 is connected to the glue application device 130. After being glued, the books can enter the drying device 111 along the first conveyor belt 111 for drying. In some embodiments, the upstream of the first conveyor belt 111 in the direction of movement can also be a different production line, such as a production line for applying glue and pressing and pasting books. Alternatively, in some embodiments, books can also be transported upstream of the first conveyor belt 111 in the direction of movement. For example, after the books are processed in the previous process, they are transferred to the upstream of the first conveyor belt 111 in the direction of movement and move sequentially along the first conveyor belt 111. In some embodiments, books are moved along the first conveyor belt 111 in a flat position, one book at a time. The direction of movement of the first conveyor belt 111 is not limited to a single direction. In some embodiments, the first conveyor belt 111 has bends, and the direction of movement may be different at different positions on the first conveyor belt 111.
[0035] A drying chamber 112 is mounted on a first conveyor belt 111, and books move along the first conveyor belt 111 and pass through the drying chamber 112. In some embodiments, the drying chamber 112 includes multiple microwave generators 1121, which are arranged along the first conveyor belt 111. As the books move along the first conveyor belt 111 and pass through the drying chamber 112, the microwave generators 1121 heat the moisture in the books. Microwaves have strong penetrating power and have minimal impact on the inner pages of the books, resulting in high drying efficiency. In some embodiments, the drying chamber 112 can also perform drying by other methods, such as hot air, infrared, etc., or the drying chamber 112 can include multiple drying methods simultaneously, which helps to improve the applicability of the book gluing drying system 100.
[0036] See Figure 1The circulation device 113 is located on the side of the drying chamber 112 downstream of the direction of movement of the first conveyor belt 111. In some embodiments, the drying chamber 112 includes an outer cover that can suppress heat dissipation, improve drying efficiency, and reduce the impact on other equipment in the workshop. When drying books, the moisture in the books and glue evaporates, forming hot and humid air inside the outer cover. This hot and humid air may affect drying efficiency; for example, if the moisture content in the air is too high, the drying efficiency and drying effect will decrease.
[0037] The circulation device 113 is located on the downstream side of the drying chamber 112 near the direction of movement of the first conveyor belt 111. For example, the circulation device 113 is located downstream of the outer casing of the drying chamber 112 along the direction of movement of the first conveyor belt 111. It can condense the humid and hot air in the outer casing and transport the condensed dry air to the upstream side of the drying chamber 112 near the direction of movement of the first conveyor belt 111, thereby realizing air circulation inside the drying chamber 112, reducing air humidity, and improving drying efficiency and drying effect.
[0038] See Figure 1 In some embodiments, the circulation device 113 may include a fan 1131, a condenser 1132, a filter 1133, and a circulation air duct 1134. Air in the drying chamber 112 near the downstream side of the first conveyor belt 111 passes sequentially through the fan 1131, the condenser 1132, and the filter 1133 to form dry air. The dry air is then transported along the circulation air duct 1134 to the upstream side of the drying chamber 112 near the first conveyor belt 111.
[0039] The fan 1131 draws in humid, hot air from inside the drying chamber 112, passing the air sequentially through the condenser 1132 and the filter 1133. Further, the condenser 1132 includes, for example, an evaporator 1135 and a compressor 1136, which use a refrigerant to condense moisture in the humid, hot air, forming dry air. In some embodiments, the condenser 1132 also includes a water tank 1137 to receive condensate. The filter 1133 filters the condensate or air, reducing the risk of pipe blockage.
[0040] In some embodiments, the circulation device 113 may also dry the humid air using other methods. For example, the circulation device 113 includes a fan and a duct filled with a desiccant. The fan drives the humid air through the desiccant, which dries the humid air. The dried air then re-enters the drying chamber 112 to achieve air circulation. In some embodiments, the circulation device 113 may also dry the humid air using an electric heating device or other methods, which are not limited in this embodiment.
[0041] The cooling device 120 is located downstream of the drying device 110 along the direction of movement of the first conveyor belt 111. The cooling device 120 is used to cool the dried books to prevent heat buildup inside the books and the resulting fire hazard. See also... Figure 1 The cooling device 120 includes a second conveyor belt 121 and a cooling box 122. The second conveyor belt 121 is located downstream of the first conveyor belt 111 in its direction of movement and is connected to the first conveyor belt 111. In some embodiments, the first conveyor belt 111 and the second conveyor belt 121 can be directly connected. In some embodiments, the first conveyor belt 111 and the second conveyor belt 121 can be connected by a transfer mechanism. The first conveyor belt 111 and the second conveyor belt 112 are controlled separately; for example, the movement speeds of the first conveyor belt 111 and the second conveyor belt 112 can be different, or the first conveyor belt 111 or the second conveyor belt 112 can be paused or reversed to extend the drying or cooling time of the books and improve the drying or cooling effect.
[0042] The cooling chamber 122 is mounted on the second transmission belt 121, and the book enters the cooling chamber 122 along the second transmission belt 121. The cooling chamber 122 includes, for example, a cold air blower 123, which can deliver cold air into the interior of the cooling chamber 122 to cool the book.
[0043] In some embodiments, the cooling chamber 122 includes an outer casing, with a cooling fan 123 disposed inside or outside the casing. The outer casing can restrict the direction and range of cold air flow, improving the cooling effect. Furthermore, the cooling chamber 122 can also dry the cold air introduced into the outer casing, for example, by using a desiccant, reducing the risk of the books reabsorbing moisture during the cooling process.
[0044] In this embodiment, the drying device 110 and the cooling device 120 are connected in a line, which can improve the drying efficiency and shorten the drying time of the book. This helps reduce the risk of water absorption by the inner pages of the book, further improving the drying effect. The circulation device 113 can further reduce the moisture content of the air in the drying device 110, converting hot, humid air into dry air and achieving air circulation, further improving the drying efficiency and effect of the book. The book glue drying system in this embodiment significantly shortens the drying time of the book, reduces the risk of water absorption and deformation of the inner pages, and helps improve the quality of the book.
[0045] See Figure 1In some embodiments, the book gluing and drying system 100 further includes a gluing device 130. The gluing device 130 is located upstream of the drying device 110 along the movement direction of the first conveyor belt 111. After the book has been glued, it can enter the drying device 110 for drying. In some embodiments, the gluing device 130 can also perform adhesive processing on the book. For example, after applying glue to the inner pages of the book, the gluing device 130 can press the book together, for example, partially bonding and fixing adjacent inner pages to form a thicker, stronger, and less tear-resistant "board book".
[0046] In some embodiments, the glue application device 130 includes an anilox roller (not shown), which can form a uniform thickness of glue on the inner pages of the book. The glue application device 130 improves the uniformity of glue distribution by using the anilox roller, which helps avoid glue concentration in certain areas, improves bonding strength, and enhances drying efficiency. In some embodiments, the glue application device 130 can also apply glue using a sponge strip and utilize a scraper to evenly distribute the glue on the inner pages.
[0047] In some embodiments, the anilox roller has a pattern shape that is one or more of diamond, diagonal, or wavy. The pattern shape of the anilox roller can improve the uniformity of adhesive distribution on the inner pages. In some embodiments, the density of the anilox roller pattern can be selected according to the flowability of the adhesive used and its adhesion properties on the inner pages of the book, reducing adhesion and improving the uniformity of adhesive distribution on the inner pages.
[0048] In some embodiments, the amount of adhesive applied to the inner pages by the anilox roller is 5-15 grams per square meter. For example, the amount of adhesive applied to the inner pages may be 5 grams per square meter, 7 grams per square meter, 9 grams per square meter, 10 grams per square meter, 12 grams per square meter, or 15 grams per square meter. Specifically, the amount of adhesive applied to the inner pages can be controlled by adjusting the distance between the anilox roller and the inner pages. The amount of adhesive can be adjusted according to the bonding strength between the inner pages to ensure stable adhesion and prevent delamination. Furthermore, it reduces the porosity of the adhesive on the inner page surface, minimizing the risk of bulging due to air expansion within the pores during the book drying process.
[0049] In some embodiments, the drying efficiency of the drying device 110 can be adjusted according to the amount of glue. For example, when the amount of glue is large, the output power of the drying chamber 112 in the drying device 110 can be increased, or the movement speed of the first conveyor belt 111 can be reduced to prolong the time the book spends in the drying chamber 112 and ensure the drying effect. Conversely, when the amount of glue is small, the output power of the drying chamber 112 can be reduced, or the movement speed of the first conveyor belt 111 can be increased to avoid over-drying the book, which could cause the inner pages to become brittle and affect product quality.
[0050] join Figure 1 and Figure 2 In some embodiments, the drying device 110 further includes a first sensor 114. The first sensor 114 is disposed near the circulation device 113 and can acquire the temperature and / or humidity of the dry air output by the circulation device 113. The first sensor 114 may include, for example, an infrared thermometer, a thermocouple thermometer, a capacitive humidity detector, etc.
[0051] In some embodiments, the first sensor 114 may be disposed inside the outer casing of the drying chamber 112 to acquire the temperature and humidity of the air inside the casing. The temperature and humidity acquired by the first sensor 114 can indicate the drying effect on the books. Furthermore, in some embodiments, a display panel may be disposed on the outside of the drying chamber 112, which can display the data acquired by the first sensor 114, allowing the user to monitor the drying effect on the books.
[0052] In some embodiments, the drying chamber 112 includes a plurality of first sensors 114, which are distributed at different positions inside the outer cover of the drying chamber 112. Users can comprehensively analyze the drying effect on books based on the plurality of first sensors 114.
[0053] See Figure 1 and Figure 2 The cooling device 120 includes a second sensor 124. The second sensor 124 is located downstream of the cooling chamber 122 along the movement direction of the second conveyor belt 121 and can acquire the temperature and / or humidity of the books. The second sensor 124 may include, for example, an infrared thermometer, a thermocouple thermometer, or a capacitive humidity detector. The second sensor 124 can acquire the temperature and / or humidity of the books after drying and cooling, thereby obtaining the drying effect of the books after passing through the book resin drying system. In some embodiments, the second sensor 124 may be located at the book outlet position in the cooling chamber 122.
[0054] In some embodiments, the cooling device 120 may further include a display panel. The display panel can display the temperature and / or humidity of the book. The user can obtain the effect of the book after drying and cooling based on the display panel, and further, can guide adjustments to the book gluing and drying system 100. For example, adjusting the power of the drying chamber 112 or the movement speed of the first conveyor belt 111 and the second conveyor belt 121, so that the book meets the temperature and / or humidity requirements when it is output from the cooling chamber 122, wherein the temperature and / or humidity requirements can, for example, meet the conditions for the book to be directly stacked and stored.
[0055] See Figure 2The book gluing and drying system 100 also includes a processor 140. The processor 140 is signal-connected to a first sensor 114 and a second sensor 124. The processor 140 is also signal-connected to a first conveyor belt 111 and a microwave generator 1121. The processor 140 can receive signals output from the first sensor 114 and the second sensor 124, and control the speed of the first conveyor belt 111 and / or the output power of the microwave generator 1121 based on these signals.
[0056] The first sensor 114 and the second sensor 124 can acquire the drying effect on the book, and the processor 140 can realize automated control. For example, a temperature and / or humidity threshold for the book can be preset. When the temperature and / or humidity values acquired by the second sensor 124 meet the threshold, the book gluing and drying system 100 is controlled to operate stably. When the temperature and / or humidity acquired by the second sensor 124 exceeds the threshold, the speed of the first conveyor belt 111 and the power of the microwave generator 1121 are adjusted to make the temperature and / or humidity of the book meet the threshold.
[0057] Furthermore, the change in the signal between the first sensor 114 and the second sensor 124 can also indicate the working status of the book gluing and drying system 100. For example, if the humidity signal acquired by the second sensor 124 is significantly greater than the humidity signal acquired by the first sensor 114, it may indicate that the cooling device 120 is malfunctioning, causing secondary moisture contamination of the book.
[0058] See Figure 2 In some embodiments, the processor 140 may also be signal-connected to the cooling device 120, for example, controlling the speed of the second conveyor belt 121 and the power of the air cooler 123 based on signals from the first sensor 114 and the second sensor 124. This optimizes the cooling effect of the cooling device 120 on the book and improves the efficiency of cooling the book.
[0059] See Figure 1In some embodiments, the cooling box 122 includes an air inlet 1221 and an air outlet 1222. The air inlet 1221 is located upstream of the second conveyor belt 121 in the direction of movement, and a cooling fan 123 is connected to the air inlet 1221. The air inlet 1221 allows cold air to enter the interior of the cooling box 122's outer casing. Preferably, in some embodiments, the air inlet 1221 is located below the outer casing of the cooling box 122. The air outlet 1222 is located downstream of the second conveyor belt 121 in the direction of movement, and is used to expel hot air that has absorbed heat from the books. Preferably, the air outlet 1222 is located above the outer casing of the cooling box 122. The direction of movement of the second conveyor belt 121 is not limited to a single direction. In some embodiments, the second conveyor belt 121 has bends, and the direction of movement may differ at different locations on the second conveyor belt 121.
[0060] In some embodiments, the air cooler includes, for example, a surface cooler, an evaporator, a condenser, and a fan. Air is drawn from the outside and its temperature and humidity are reduced before being introduced into the outer casing of the cooling box 122 through the air inlet 1221.
[0061] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
