Description

Technical Field

[0001] The utility model generally relates to the technical field of bookbinding, and particularly to a fine binding machine. Background Art

[0002] In the production process of hardcover books, after the spine paper and end papers are pasted on the spine, it is usually lightly pressed by a flat pressing plate to promote adhesion. However, after the book core is coated with glue, it runs on the clamping book chain, and the inconsistency of the ambient temperature may cause the glue to dry, thereby affecting the viscosity of the glue. Since the large-area pressing method of the pressing plate lacks pertinence, especially for the round spine, the arc-shaped sides may not receive effective pressure, which will further exacerbate the problem of the decrease in glue viscosity. As a result, the spine may come unglued, and at this time, manual glue filling is often required to ensure the firm adhesion of the spine. This process not only increases the production cost but also reduces the production efficiency.

[0042] The preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not intended to limit the present utility model.

[0043] Figure 1 A schematic diagram of a precision assembly machine 100 according to an embodiment of the present utility model is shown. The following will be described in detail in conjunction with Figure 1 this.

[0044] As Figure 1As shown in the figure, the precision binding machine 100 includes a conveying device 110, a feeding device 120, a hot air device 130, and a first pressing device 140. The conveying device 110 can convey the book core along a preset transmission path. Optionally, the conveying device 110 is a book clamping chain. When the book core is conveyed by the conveying device 110, the spine of the book core faces upward. Both the feeding device 120 and the hot air device 130 are arranged on the transmission path. Among them, the hot air device 130 is located upstream or downstream of the feeding device 120 (the upstream and downstream are distinguished by the conveying direction of the conveying device 110). The feeding device 120 can place the spine paper on the spine of the book core; the hot air device 130 can blow hot air to the book core to prevent or delay the drying of the glue, keep the viscosity of the glue in a good state, and thus reduce the adverse effect of the ambient temperature on the performance of the glue. The first pressing device 140 is arranged downstream of the feeding device 120 and the hot air device 130, and includes a pressing wheel 141 arranged above the transmission path. The pressing wheel 141 is used to press the spine to firmly bond the spine paper to the book core. Specifically, a pressing surface 1411 is arranged on the circumferential side of the pressing wheel 141, and the shape of the pressing surface 1411 is adapted to the shape of the spine to better fit the spine and ensure that each position of the spine can receive appropriate pressure. Optionally, Figure 2 shows a schematic diagram of the pressing wheel 141 according to an embodiment of the present invention, as Figure 2 shown, the pressing surface 1411 of the pressing wheel 141 can be a cylindrical surface. Such a pressing wheel 141 can fit the spine of a square-spine book core, ensuring that each position of the spine can receive appropriate pressure, thereby improving the bonding effect between the spine paper and the book core. Figure 3 shows a schematic diagram of the pressing wheel 141 according to an embodiment of the present invention, as Figure 3 shown, the pressing surface 1411 of the pressing wheel 141 can be a groove surface, and the cross-sectional contour of the groove surface is arc-shaped. Such a pressing wheel 141 can fit the spine of a round-spine book core, ensuring that each position of the spine can receive appropriate pressure, thereby improving the bonding effect between the spine paper and the book core.

[0045] According to an embodiment of the present invention, as Figure 1 shown, the pressing wheel 141 can be a solid wheel, an inflated wheel or a hollow wheel. Figure 4 shows an exploded view of a solid wheel according to an embodiment of the present invention, as Figure 4 shown, the solid wheel can include a wheel shaft 1412 and a wheel rim 1413. The wheel rim 1413 is connected to the wheel shaft 1412, and the wheel rim 1413 is an annular body made of metal or other materials. For square-spine book cores and round-spine book cores with a relatively small face width dimension (for example: square-spine book cores with a face width dimension of 10 - 30 mm and round-spine book cores with a face width dimension of 25 - 55 mm), a solid wheel can be used for pressing to ensure the bonding effect of the spine. Figure 5FIG. 4 shows an exploded view of an inflatable wheel according to an embodiment of the present utility model. Figure 5 As shown, the pneumatic wheel includes a first rim 1414, a first adhesive film 1415, two sealing pressing sheets 1416 and an air nozzle 1417, wherein the first adhesive film 1415 is sleeved on the first rim 1414, and the two sealing pressing sheets 1416 are respectively connected to the two ends of the first rim 1414 to compress and seal the first adhesive film 1415. An air-filling cavity is formed between the first adhesive film 1415 and the first rim 1414, and the air nozzle 1417 is installed on a sealing pressing sheet 1416 and communicated with the air-filling cavity, and air can be inflated into the air-filling cavity through the air nozzle 1417 to prop up the first adhesive film 1415. Figure 6 FIG. 4 shows an exploded view of a hollow wheel according to an embodiment of the present utility model. Figure 6 As shown, the hollow wheel may include a second rim 1418 and a second adhesive film 1419, the second rim 1418 is provided with a weight reduction structure, and the second adhesive film 1419 is sleeved on the second rim 1418. For round-spine book blocks with larger width dimensions (for example, round-spine book blocks with a width dimension greater than 55 mm), a hollow wheel may be used for compaction, and for square-spine book blocks with larger width dimensions (for example, square-spine book blocks with a width dimension greater than 30 mm), an inflatable wheel may be used. The hollow wheel and the inflatable wheel have the characteristics of light weight and easy rotation, thereby providing a more uniform and precise compaction effect, while avoiding the phenomenon of spine paper rubbing caused by excessive friction, thereby ensuring the bonding quality of spine paper and book blocks.

[0046] Figure 7 FIG. 1 shows a top view of a first pressing device 140 according to an embodiment of the present utility model. Figure 1 and Figure 7As shown in the figure, the first pressing device 140 may further include a column 142, a swing arm 143, a locking member 144, and a mounting arm 145. The column 142 is disposed on one side of the conveying device 110. The swing arm 143 is pivotally connected to the side of the column 142 close to the conveying device 110. The mounting arm 145 is connected to the free end of the swing arm 143 and is perpendicular to the swing arm 143. The pressing wheel 141 is detachably connected to the mounting arm 145. By rotating the swing arm 143, the height of the pressing wheel 141 can be easily adjusted to precisely adjust the pressing force applied by the pressing wheel 141 to the book core (spine paper). In addition, the adjustable height of the pressing wheel 141 also enables the pressing wheel 141 to adapt to book cores of different widths, meeting diverse binding requirements. The locking member 144 is connected to the swing arm 143 and functions to fix the position of the swing arm 143, thereby locking the height of the pressing wheel 141 to ensure the required pressing force is maintained during the binding process. Optionally, the locking member 144 is a nut. The column 142 is provided with a mounting hole. The swing arm 143 includes a first connecting section 1431 and a second connecting section 1432 that are perpendicular to each other. Among them, the first connecting section 1431 is connected to the mounting arm 145, and the second connecting section 1432 is provided with an external thread. The second connecting section 1432 passes through the column 142 from the mounting hole and is threadedly connected to the locking member 144. With the above design, the user can easily rotate the swing arm 143 after loosening the locking member 144 to adjust the height of the pressing wheel 141. After completing the adjustment of the height of the pressing wheel 141, the user can tighten the locking member 144 to fix the position of the swing arm 143 and thereby lock the height of the pressing wheel 141.

[0047] According to an embodiment of the present invention, as Figure 1 shown in the figure, the hot air device 130 may include an air duct 131. The air duct 131 is disposed above one side of the transmission path. A plurality of air outlets are spaced apart on the air duct 131, and the air outlets face the transmission path. The air duct 131 can be connected to a hot air source, and the hot air source provides hot air for the air duct 131. The air duct 131 guides the hot air to the book core, thereby preventing or delaying the drying of the glue and keeping the viscosity of the glue in a good state. Optionally, there are two hot air devices 130. Among them, one hot air device 130 is disposed upstream of the feeding device 120, and the other hot air device 130 is disposed downstream of the feeding to keep the viscosity of the glue in a good state. Optionally, the two hot air devices 130 can share a hot air source. In some embodiments, a heat source (such as a heater) and a air source (such as a blower) can also be integrated into the air duct 131.

[0048] According to an embodiment of the present invention, as Figure 1As shown, the fine binding machine 100 may further include a second pressing device 150. The second pressing device 150 is located downstream of the feeding device 120 and the hot air device 130, and also upstream of the first pressing device 140. The second pressing device 150 includes a pressing plate 151 and a lifting mechanism 152. The pressing plate 151 may be a flat plate, which is arranged directly above the conveying device 110 (transmission path). The lifting mechanism 152 is connected to the pressing plate 151 and is configured to drive the pressing plate 151 to rise and fall, so that the pressing plate 151 presses the book core and the spine paper. Optionally, the lifting mechanism 152 may be a linear actuator such as a cylinder, a hydraulic cylinder, or an electric push rod. By sequentially arranging the second pressing device 150 and the first pressing device 140 downstream of the feeding device 120 and the hot air device 130, multiple presses on the book core and the spine paper can be achieved, thereby improving the bonding effect between the book core and the spine paper and reducing the possibility of delamination.

[0049] According to an embodiment of the present invention, as Figure 1 shown, the fine binding machine 100 further includes an adhesive application wheel 160. The adhesive application wheel 160 is used to apply glue to the spine of the book core. Specifically, the adhesive application wheel 160 is arranged directly above the conveying device 110 and is located upstream of the feeding device 120 and the hot air device 130. When the book core passes under the adhesive application wheel 160, the adhesive application wheel 160 can apply the glue to the spine of the book core.

[0050] Compared with the prior art, the embodiment of the present invention provides a fine binding machine 100. By arranging the hot air device 130 upstream or downstream of the feeding device 120, hot air can be blown to the book core on the conveying device 110 to prevent or delay the drying of the glue, so that the viscosity of the glue remains in a good state, thereby reducing the adverse impact of the ambient temperature on the performance of the glue. By setting the pressing surface 1411 of the pressing wheel 141 as a cylindrical surface or a groove surface, the pressing wheel 141 can better fit the spine, ensuring that each position of the spine can receive appropriate pressure, thereby significantly improving the bonding effect between the spine paper and the book core and reducing the possibility of delamination.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
