[0031] The embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the 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.

[0032] Figure 1 The structure of the binding device 1 in some embodiments according to the present utility model is shown. The following will be combined with Figure 1 to describe the binding device 1.

[0033] As Figure 1As shown in the figure, the binding device 1 includes a binding table 11, a perforating device 12, a threading device 13, and a locking device 14. The binding table 11 can support and fix the book block 2. For example, the binding table 11 includes at least one flat surface, and the book block 2 can be placed above the binding table 11 in an unfolded form. The book block 2 refers to multiple printed pages folded and stacked in a stack according to the page number and layout order, and the edge positions can be cut, or can be cut after binding. The center seam position of the book block 2 refers to the middle line of the fold in the book block 2. After binding, the center seam is close to the spine position of the book.

[0034] In this embodiment, the binding table 11 is provided with a slit 111 at a preset position. When the book block 2 is placed on the binding table 11, the center seam position of the book block 2 covers the slit 111. According to some preferred embodiments of the present invention, the binding table 11 includes two support panels 112 forming a preset angle. The support panels 112 are, for example, flat surfaces, and one side of the two support panels 112 is close to each other and forms a preset angle. The preset angle is greater than 90° and less than 180°. Preferably, the angle between the two support panels 112 is approximately 130° - 150°. That is to say, the two support panels 112 are connected to each other at an obtuse angle. The slit 111 is located at the angle position between the two support panels 112. The unfolded angle of the book block 2 is equal to the angle between the two support panels 112 and is placed on the two support panels 112. The pages of the book block 2 are attached to the support panels 112, and the center seam position of the book block 2 is aligned with the angle position between the two support panels 112. In this embodiment, the two support panels 112 connected at an obtuse angle can improve the stability of the book block 2 placed on the support panels 112, reduce the risk of the book block 2 sliding laterally on the support panels 112, and provide space within the angle between the two support panels 112, facilitating the arrangement of the perforating device 12 and the locking device 14.

[0035] The perforating device 12 is arranged below the binding table 11, and the position of the perforating device 12 is aligned with the position of the slit 111. The perforating device 12 can penetrate the book block 2 from the position of the slit 111 to form binding holes 21 in the book block 2 (see Figure 2 ). Specifically, for example, the perforating device 12 includes a perforating needle 121. The perforating needle 121 can extend from the position of the slit 111 and penetrate the book block 2 at the center seam position of the book block 2 to form binding holes 21 in the book block 2.

[0036] The threading device 13 is arranged above the binding table 11, and the threading device 13 can drive the binding thread 131 to pass through the binding holes 21 on the book block 2. The threading device 13 includes, for example, a threading needle 132. A through hole is formed in the threading needle 132, and the binding thread 131 can pass through the through hole. When the threading needle 132 moves and passes through the binding hole 21, it drives the binding thread 131 to pass through the binding hole 21. A part of the binding thread 131 moves to the side of the book block 2 facing the gap 111 (the inner side when the book block 2 is opened), facilitating the locking device 14 to operate on the binding thread 131 and lock the binding thread 131 on the side of the book block 2 facing the gap 111.

[0037] The locking device 14 is arranged below the binding table 11 and corresponds to the position of the gap 111. In some embodiments, the positions of the punching device 12 and the locking device 14 may interfere with each other. Preferably, the punching device 12 and the locking device 14 are arranged to be relatively movable. For example, first control the punching device 12 to move to the position corresponding to the gap 111, form the binding holes 21 on the book block 2, then control the punching device 12 to move out of the way, and control the locking device 14 to move to the position corresponding to the gap 111 to lock the binding thread 131.

[0038] In different embodiments, the locking device 14 can fixedly connect the binding thread 131 and the book block 2 by pressing, pasting, hot melting, etc. Correspondingly, the binding thread 131 can be arranged to cooperate with the locking device 14. The binding thread 131 is, for example, a paper yarn or a hot melt thread, which will be specifically described in the subsequent embodiments.

[0039] The binding device 1 in this embodiment can bind the book blocks 2 together using the binding thread 131 without using galvanized iron nails, without scratching or damaging the book pages or having the risk of pricking, and the binding thread 131 can be recycled together with the book block, reducing the recycling cost.

[0040] Figure 2 The structure of the punching device 12 and the threading device 13 of the binding device 1 in some embodiments according to the present invention is shown. Figures 3A - 3F The process of mutual cooperation between the threading device 13 and the locking device 14 in some embodiments according to the present invention is shown. The following will be described in conjunction with Figures 2 - 3F for illustration.

[0041] As Figure 2 shown, according to the preferred embodiment of the present invention, the punching device 12 includes two punching needles 121, and the positions of the two punching needles 121 are relatively fixed. The needles of the two punching needles 121 face the book block 2 and pass through at the center seam position of the book block 2. After passing through the book block 2, two binding holes 21 with a fixed spacing are formed.

[0042] The threading device 13 includes a threading needle 132, preferably one threading needle 132. The threading needle 132 drives the binding thread 131 to pass through two threading holes 21 in sequence. For example Figures 3A - 3E As shown in, in an embodiment of the present utility model, the threading needle 132 is aligned with one of the two binding holes 21 (for example Figure 2 the left binding hole 21 in), and drives the binding thread 131 to pass through this binding hole 21. The locking device 14 retains a part of the binding thread 131 on the side of the book block 2 facing the binding table 11. The threading needle 132 is pulled out from this binding hole 21 and transferred to be aligned with the other binding hole 21, and drives the binding thread 131 to pass through the other binding hole 21. The locking device 14 retains the binding thread 131 at the position of the other binding hole 21, so that the binding thread 131 surrounds between the two threading holes 21, and locks the binding thread 131 to fix the book block 2. Taking two fixedly spaced binding holes 21 and the binding thread 131 surrounding between the two binding holes 21 as a group, in a preferred embodiment of the present utility model, multiple groups of binding holes 21 and corresponding binding threads 131 can be formed at different positions of the center seam of the book block 2 to improve the bonding strength between the binding thread 131 and the book block 2.

[0043] According to a preferred embodiment of the present utility model, as Figure 3A and Figure 3D shown, the locking device 14 includes a thread-hooking plate 141 and a pressing plate 142. The thread-hooking plate 141 is movable relative to the threading device 13. After the threading device 13 drives the binding thread 131 to pass through the binding hole 21, the thread-hooking plate 141 drives the binding thread 131 to move along a direction non-parallel to the binding hole 21.

[0044] For example Figure 3A and Figure 3B As shown in, the thread-hooking plate 141 has a groove. When the threading device 13 drives the binding thread 131 to move to the lower part of the book block 2, the binding thread 131 is bent in a U shape. The groove of the thread-hooking plate 141 hooks the U-shaped bending position of the binding thread 131, and drives the binding thread 131 to move horizontally (non-parallel to the vertical direction of the threading hole 21) from left to right, so as to pull a part of the binding thread 131 to a position in the center seam of the book block 2 where no binding hole 2 is formed.

[0045] The position of the pressing plate 142 corresponds to the position of the gap 111, and the pressing plate 142 is arranged to fix the binding thread 131 on the side of the book block 2 facing the binding table 11 (for example Figure 3DOn the side facing downward (towards the bottom). According to a preferred embodiment of the present invention, the binding thread 131 melts or becomes sticky after heating. One side of the pressing plate 142 facing the book block 2 includes a heater 143. The pressing plate 142 is arranged to press the binding thread 131 pulled by the thread-hooking plate 141 onto the book block 2 and heat the binding thread 131 using the heater 143 so that the binding thread 131 and the book block 2 are adhered together.

[0046] Specifically, the binding thread 131 is a nylon thread. When heated by the heater 143, the nylon thread melts and adheres to the book block 2. When the temperature drops, the binding thread 131 solidifies again and adheres to the book block 2. In some other embodiments, the binding thread 131 is, for example, a paper yarn. The paper yarn is made by impregnating plant fiber paper, cutting it into strips, and then twisting and forming. Glue is pre-coated on the paper yarn, and the glue restores its stickiness after being heated by the heater 143, bonding the paper yarn and the book block 2 together.

[0047] As Figure 3C shown, according to a preferred embodiment of the present invention, the locking device 14 further includes a wire cutter 144. The wire cutter 144 is arranged to cut the binding thread 131 at a preset position after the thread-hooking plate 141 drives the binding thread 131 to move a preset distance, so as to create a break in the binding thread 131 for facilitating subsequent operations. The position where the wire cutter 144 cuts the binding thread 131 is set such that after the binding thread 131 passes through the binding hole 21, a certain distance is reserved to facilitate the pressing plate 142 to fix the binding thread 131 and ensure sufficient bonding strength between the binding thread 131 and the book block 2.

[0048] In some embodiments, as Figure 1 shown, the locking device 14 includes two thread-hooking plates 141 and two pressing plates 142. Among them, the two thread-hooking plates 141 and the two pressing plates 142 respectively correspond to two threading holes 21. For example, the perforating device 12, as described in the foregoing embodiment, includes two perforating needles 121 with relatively fixed positions. The two thread-hooking plates 141 and the two pressing plates 142 respectively correspond to these two threading holes 21, and the binding thread 131 is wound around between the two threading holes 21.

[0049] For example, in some embodiments, as Figure 3A and Figure 3B shown, when the threading needle 132 drives the binding thread 131 through the left threading hole 21, the left thread-hooking plate 141 among the two thread-hooking plates 141 drives the binding thread 131 to move from left to right. As Figure 3D shown, the left pressing plate 142 among the two pressing plates 142 presses the binding thread 131 onto the book block 2 and makes the binding thread 131 fixedly connected to the book block 2.

[0050] As Figure 3EAs shown, when the thread-passing needle 132 drives the binding thread 131 through the right thread-passing hole 21, the right hook-shaped thread board 141 of the two hook-shaped thread boards 141 drives the binding thread 131 to move from right to left. As Figure 3F shown, the right pressing plate 142 of the two pressing plates 142 presses the binding thread 131 against the book block 2, and makes the binding thread 131 fixedly connected to the book block 2.

[0051] Furthermore, after the left hook-shaped thread board 141 drives the binding thread 131 to move a preset distance, the thread cutter 144 cuts the binding thread 131 to form a break. After the right hook-shaped thread board 141 drives the binding thread 131 to move a preset distance, the thread cutter 144 cuts the binding thread 131, and another break is formed on the binding thread 131. And both breaks of the binding thread 131 are located on the side of the book block 2 facing the binding table 11. As Figure 3F shown, the binding thread 131 forms a structure similar to a staple. After both ends of the binding thread 131 pass through the two binding holes 21, they are located on the side of the book block 2 facing the binding table 11 and surround between the two binding holes 21.

[0052] In some embodiments, both ends of the binding thread 131 are attached to the book block 2 between the two thread-passing holes 21, and both ends of the binding thread 131 are close to or overlap each other, which is beneficial to improving the bonding strength between the binding thread 131 and the book block 2.

[0053] As Figure 1 shown, according to a preferred embodiment of the present invention, the binding table 11 further includes a first limiting member 113. The first limiting member 113 is located above the gap 111 and is configured to press the book block 2 against the support panel 112. Specifically, for example, the first limiting member 113 can move relative to the support panel 112 so that the book block 2 can be placed between the support panel 112 and the first limiting member 113. When the book block 2 is unfolded and placed between the support panel 112 and the first limiting member 113, the first limiting member 113 presses against the book block 2. The first limiting member 113 can improve the stability of the book block 2 on the binding table 11, reduce the risk of driving the book block 2 to deviate from its position when the punching device 12, the thread-passing device 13 or the locking device 14 acts on the book block 2, and improve the binding quality of the book block 2.

[0054] Preferably, the first limiting member 113 is configured in the shape of a roller with a groove and presses against the back side of the middle seam of the book block 2. Furthermore, the binding table 11 includes two first limiting members 113, and the two first limiting members 113 respectively press against the positions near both ends of the middle seam of the book block 2.

[0055] As Figure 1As shown, according to a preferred embodiment of the present utility model, the binding table 11 further includes a second limiting member 114. When the book block 2 is placed on the binding table 11, at least one end of the center seam of the book block 2 abuts against the second limiting member 114. The second limiting member 114 can fix the book block 2. Preferably, there are two second limiting members 114 on the binding table 11, and both ends of the center seam of the book block 2 respectively abut against the two second limiting members 114.

[0056] Preferably, the position of the second limiting member 114 on the binding table 11 is adjustable. For example, the second limiting member 114 is detachably arranged on the support panel 112, and the position of the second limiting member 114 can be adjusted according to the size of the book block 2.

[0057] Finally, it should be noted that the above are only embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
