DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Embodiment 1

[0037] like Figure 1 and Figure 2As shown, a preferred embodiment of the small glue binder of the present invention comprises an inner page clamping mechanism 1 for clamping inner pages, a gluing mechanism 2 for gluing inner pages, a cover clamping mechanism 3 for gluing covers and inner pages, and a frame 4 for installing the inner page clamping mechanism 1, the gluing mechanism 2, and the cover clamping mechanism 3. The gluing mechanism 2 and the cover clamping mechanism 3 are both installed on the frame 4, and the gluing mechanism 2 and the cover clamping mechanism 3 are arranged side by side. The inner page clamping mechanism 1 is installed on the frame 4 through a telescopic rail, and the telescopic rail can be expanded and retracted. The frame 4 has an avoidance opening 41 to ensure that the telescopic rail can be expanded from the avoidance opening 41, so that the inner page clamping mechanism 1 is suspended. During the expansion or contraction of the telescopic rail, the inner page clamping mechanism 1 passes through the gluing device, and at this time, the gluing device will glue the inner pages on the inner page clamping mechanism 1. When in standby and unused state, the telescopic rail 5 is in a retracted state. When the telescopic rail 5 is in a retracted state, the inner page clamping mechanism 1 is located above the cover clamping mechanism 3; when binding, the inner page clamping mechanism 1 is translated, and the telescopic rail 5 is gradually expanded. When the inner page clamping mechanism 1 passes through the gluing mechanism 2, the gluing mechanism 2 glues the inner page clamped by the inner page clamping mechanism 1. After the telescopic rail 5 is fully expanded, it gradually shrinks until it is fully retracted, and the inner page clamping mechanism 1 returns to the top of the cover clamping mechanism 3, thus completing the gluing work of the inner page; then the cover is placed on the cover clamping mechanism 3, and the cover and the inner page are glued together by the cover clamping mechanism 3. The telescopic rail 5 usually adopts two, so that the inner page clamping mechanism 1 can remain stable during the movement. The telescopic rail 5 can reduce the length of the rail, thereby reducing the length of the entire horizontal binder, while not increasing the width. The entire horizontal binder occupies a small space. The telescopic rail 5 can ensure that the inner page clamping mechanism 1 carried by it will not deflect or skew when it is expanded or retracted. It should be known that the telescopic rail 5 can also be installed on only one side; the telescopic rail 5 is a common component in daily life, and the cross-section of the telescopic rail 5 is usually C-shaped, and can be a two-stage or three-stage type. Those skilled in the art are well aware of the telescopic structure and principle, and the specific telescopic structure and principle will not be repeated here.

[0038] The inner page clamping mechanism 1 is provided with a moving handle 6, which is convenient for pushing the moving handle 6 to drive the inner page clamping mechanism 1 to move; the moving handle 6 is arranged vertically, which is convenient for holding without interfering with other parts. In other embodiments, it is also possible not to provide a moving handle 6, and directly push the inner page or the inner page clamping mechanism 1 to move, so that the inner page clamping mechanism 1 can drive the inner page to move. The inner page clamping mechanism 1 in this embodiment adopts the existing manual inner page clamping mechanism 1, and the use of the manual inner page clamping mechanism 1 can reduce costs.

[0039] like Figure 3 and Figure 4As shown, the gluing mechanism 2 includes a glue box 21 for containing glue, a glue roller 22 for applying glue to the inner pages, and a rotating shaft 23 for installing the glue roller 22. The rotating shaft 23 is rotatably arranged on the glue box 21. The rotation of the rotating shaft 23 drives the glue roller 22 to rotate. The rotation of the glue roller 22 applies the glue in the glue box 21 to the inner pages passing through the glue roller 22.

[0040] In another embodiment, in order to better glue the inner pages, a paging mechanism for separating the inner pages can be provided between the gluing mechanism 2 and the cover clamping mechanism 3, or a glue roller 22 with a paging function can be used to further reduce the length. After the lower ends of the inner pages are separated, the glue roller 22 can apply glue to the sides of the inner pages, giving the inner pages more feet, thereby improving the binding effect, and the paging function can be increased as needed.

[0041] In order to reduce the number of parts, a linkage assembly 7 is also provided for the linkage between the inner page clamping mechanism 1 and the gluing mechanism 2. When the inner page clamping mechanism 1 is moving, the inner page clamping mechanism 1 drives the gluing mechanism 2 to gluing through the linkage assembly 7. Of course, in other embodiments, the linkage assembly 7 may not be used. The linkage assembly 7 includes a linkage gear 71 for connecting the gluing mechanism 2, a linkage rack 73 for connecting the inner page clamping mechanism 1, and an intermediate gear 72 connecting the linkage gear 71 and the linkage rack 73. The intermediate gear 72 is rotatably arranged on the frame 4. One end of the rotating shaft 23 of the gluing mechanism 2 extends to the outside of the glue box 21. The linkage gear 71 is installed on the rotating shaft 23. The linkage rack 73 is fixed on the inner page clamping mechanism 1. The intermediate gear 72 is meshed with the linkage rack 73 and the linkage gear 71 at the same time. When the inner page clamping mechanism 1 moves, it drives the linkage rack 73 to move, and the linkage rack 73 moves to drive the intermediate gear 72 to rotate, and the intermediate gear 72 rotates to drive the linkage gear 71 to rotate, and the linkage gear 71 rotates to drive the rotating shaft 23 to rotate, and the rotating shaft 23 rotates to drive the rubber roller 22 to rotate, so that the rubber roller 22 can always have glue attached to it, and the gluing effect of the inner pages is good. The transmission ratio of the intermediate gear 72 to the linkage gear 71 is greater than 1, so that it can ensure that the rotation speed of the rubber roller 22 is greater than the movement speed of the linkage rack 73, so that more glue can be applied to the inner pages. In another embodiment, it is also possible to not need to set the intermediate gear 72, and the height of the linkage rack 73 can be supported higher, so that the linkage rack 73 and the linkage gear 71 are meshed to achieve transmission.

[0042] like Figures 5 to 8As shown, the cover clamping mechanism 3 includes two cover clamping plates 31 for clamping the cover, a carrier plate 32 for carrying the cover clamping plates 31, and a cover driver 33 for lifting the carrier plate 32 and driving the two cover clamping plates 31 to move on the carrier plate 32. One side of the carrier plate 32 is hinged on the frame 4. The initial state of the carrier plate 32 is tilted to facilitate avoiding the inner page clamping mechanism 1 to drive the inner page to move. When the carrier plate 32 is lifted to a horizontal level by the cover driver 33, the cover and the inner page are attached. Two groups of slide grooves 321 are provided on the carrier plate 32, and the cover clamping plates 31 are slidably arranged in a corresponding group of the slide grooves 321. Two transmission parts 34 are installed on each of the cover clamps 31, and each group of slide grooves 321 includes two slide grooves 321. Each transmission part 34 is correspondingly provided with a slide groove 321. The cover driver 33 drives the transmission part 34 to drive the cover clamp 31 to move along the slide groove 321. When the two cover clamps 31 move toward each other on the supporting plate 32, the two cover clamps 31 will clamp the cover and the inner pages that are in contact with the inner pages, that is, clamp the cover on the inner pages to complete the binding.

[0043] The cover driver 33 includes a lever 3311 for driving the cover clamp 31 to move, a reset member 3312 for resetting the cover clamp 31, a top plate 3313 for lifting the supporting plate 32, a transmission shaft 3314 for driving the top plate 3313 and the lever 3311 to rotate, a transmission gear 3315 for driving another transmission shaft 3314 to rotate, and a driving handle 3316 for driving the transmission shaft 3314 to rotate. The transmission shaft 3314 is rotatably arranged on the frame 4. There are two transmission shafts 3314, one transmission shaft 3314 is arranged corresponding to a cover clamping plate 31, and each transmission shaft 3314 is installed with a transmission gear 3315 and two said levers 3311, the transmission gears 3315 on the two transmission shafts 3314 are meshed, and the top plate 3313 is installed on one of the transmission shafts 3314. It should be known that more top plates 3313 can be installed on the transmission shaft 3314 on which the top plate 3313 is installed, and it can be set according to needs; when the cover is glued, during the rotation of the transmission shaft 3314, the transmission shaft 3314 first drives the top plate 3313 to lift the supporting plate 32, and lifts the supporting plate 32 to a horizontal state, and then the transmission shaft 3314 drives the lever 3311 to contact the transmission member 34 of the cover clamping plate 31, so as to drive the two cover clamping plates 31 to move on the supporting plate 32. The handle 3316 is fixed on the transmission shaft 3314 near the hinged position between the support plate 32 and the frame 4. In other embodiments, the handle 3316 can also be fixed on another transmission shaft 3314. The reset member 3312 is usually a spring, and can also be other elastic members; one end of each reset member 3312 is connected to the corresponding transmission member 34. In other embodiments, the other end of the reset member 3312 can also be fixed on the support plate 32. Rotating the handle drives the corresponding transmission shaft 3314 to rotate, and the rotation of the transmission shaft 3314 simultaneously drives the corresponding gear to rotate, and the gear drives the gear on the other transmission shaft 3314 to rotate, thereby driving the other transmission shaft 3314 to rotate, that is, turning the handle, the two transmission shafts 3314 rotate synchronously in opposite directions; the rotation of the transmission shaft 3314 drives the corresponding lever 3311 and the top plate 3313 to rotate, and the top plate 3313 first lifts the supporting plate 32 to a horizontal state, the transmission shaft 3314 continues to rotate, and then the lever 3311 pushes the transmission member 34 to move in the slide groove 321, thereby pushing the cover clamping plate 31 to move along the slide groove 321. During this process, the reset member 3312 is stretched and stored force; since the two transmission shafts 3314 rotate synchronously in forward and reverse directions, the two cover clamping plates 31 move synchronously toward each other, thereby clamping the cover on the inner page to complete the binding.

[0044] like Fig. 9As shown, the transmission member 34 has a U-shaped accommodating cavity 340, and a shift rod 341 adapted to the shift rod 3311 is arranged in the U-shaped accommodating cavity 340. The shift rod 3311 pushes the shift rod 341, thereby pushing the transmission member 34 to move. Two connecting holes 342 for connecting the reset member 3312 are arranged on the transmission member 34, and each of the connecting holes 342 is connected to the U-shaped accommodating cavity 340. The connecting holes 342 are located on both sides of the transmission member 34 to ensure that the transmission member 34 moves smoothly.

[0045] The bearing plate 32 is provided with a roller 35, and the roller 35 rolls on the top plate 3313 to reduce friction. Fig.10 As shown, the top plate 3313 has a positioning notch 33131 and a walking surface 33132 connected to the positioning notch 33131; the positioning notch 33131 is used to position the roller 35, and when the roller 35 is located in the positioning notch 33131, the supporting plate 32 is in an inclined state, that is, the supporting plate 32 is in a low position; when the roller 35 is on the walking surface 33132, the supporting plate 32 is in a horizontal state, that is, the supporting plate 32 is in a gluing position, and any position of the walking surface 33132 is at the same distance from the rotating shaft 23, so that it can be ensured that when the roller 35 walks on the walking surface 33132, the supporting plate 32 is always in a horizontal state. The top plate 3313 is fan-shaped, and the surface formed by the thickness of the top plate 3313 is the side wall. The arc-shaped side wall of the top plate 3313 is the walking surface 33132. A depression is provided on the straight side wall of the top plate 3313, and the depression constitutes a positioning notch 33131. In order to prevent the roller 35 from entering another straight side wall from the walking surface 33132, the length of the walking surface 33132 is greater than the movable length of the cover clamping plate 31 in the slide groove 321.

[0046] When not in use, the inner page clamping mechanism 1 is placed above the cover clamping mechanism 3, that is, the inner page clamping mechanism 1 and the cover clamping mechanism 3 overlap in the vertical direction. When glue binding is required, first clamp the inner page on the inner page clamping mechanism 1, and then push the moving handle 6 back and forth to glue the inner page by the glue roller 22, and then place the cover on the carrier plate 32. The cover can also be placed on the carrier plate 32 when clamping the inner page; then turn the driving handle 3316, and the driving handle 3316 drives the transmission shaft 3314 to rotate, so that the carrier plate 32 first rotates to horizontal, and when the carrier plate 32 rotates to horizontal, the cover fits the glued surface of the inner page, and then the cover is clamped on the inner page by the cover clamping plate 31 to complete the glue binding. The inner page clamping mechanism 1 is installed on the frame 4 through a telescopic track, which can save length without increasing width when not in use, thereby reducing the occupied space.

[0047] Embodiment 2

[0048] like Fig.11As shown, the present embodiment is different from the first embodiment in that the structures of the gluing mechanism 2 and the inner page clamping mechanism 1 are different, and the structure of the cover driver 33 is different, as described below.

[0049] like Figures 12 to 15 As shown, the gluing mechanism 2 includes a rubber roller motor 24, a glue box 21 for containing glue, a rubber roller 22 for applying glue to the inner page, and a rotating shaft 23 for installing the rubber roller 22. The rotating shaft 23 is rotatably arranged on the glue box 21, one end of the rotating shaft 23 extends out of the glue box 21 and is connected to the output end of the rubber roller motor 24, and the other end of the rotating shaft 23 extends out of the glue box 21 and is fixed to the linkage gear 71 of the linkage assembly 7. The rubber roller motor 24 rotates to drive the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 simultaneously drives the rubber roller 22 and the linkage gear 71 to rotate, and the linkage gear 71 rotates to drive the intermediate gear 72 to rotate, and the rotation of the intermediate gear 72 drives the linkage rack 73 to move, and the movement of the linkage rack 73 drives the inner page clamping mechanism 1 to move. A power device is realized to simultaneously drive the rubber roller 22 and the inner page clamping mechanism 1 to move.

[0050] The cover driver 33 includes two first nut sleeves 3321 for driving the corresponding transmission member 34 to move, a first screw rod 3322 for driving the two first nut sleeves 3321 to move toward or in the opposite direction at the same time, a first driving motor 3323 for driving the first screw rod 322 to rotate, a driving wheel 3324 for lifting the carrier plate 32, and a second driving motor 3325 for driving the driving wheel 3324 to rotate eccentrically. The first driving motor 3323 can be installed on the carrier plate 32, the first screw rod 3322 is connected to the output end of the first driving motor 3323, the first screw rod 3322 has two oppositely spiral thread segments, the two first nut sleeves 3321 are respectively screwed on different thread segments of the first screw rod 3322, the first nut sleeve 3321 is also fixed to the corresponding transmission member 34, and the transmission member 34 is a bent plate. When the cover needs to be clamped, the first drive motor 3323 drives the first screw 3322 to rotate, and the first screw 3322 drives the two first nut sleeves 3321 to move toward each other, thereby driving the two cover clamping plates 31 to move toward each other to complete the clamping of the cover and the inner page. The first drive motor 3323 rotates in the opposite direction to loosen the cover. The drive wheel 3324 is eccentrically installed at the output end of the second drive motor 3325, so that the second drive motor 3325 drives the drive wheel 3324 to rotate, which can change the supporting plate 32 from an inclined state to a horizontal state. The second drive motor 3325 rotates the supporting plate 32 in the opposite direction to change the horizontal state to an inclined state. The use of electric drive can reduce components such as transmission shafts and synchronous gears, and the mechanical structure becomes simple and easy to maintain.

[0051] The inner page clamping mechanism 1 includes an inner page clamping plate 11 for clamping inner pages, an inner page electric driver 12 for driving the inner page clamping plate 11 to move toward or in the opposite direction, and a mounting frame 13 for installing the electric driver. The inner page electric driver 12 includes two driving components 120, each driving component 120 corresponds to an inner page clamping plate 11, and the driving component 120 is used to drive the inner page clamping plate 11. Each driving component 120 includes a second nut sleeve 121 for driving the inner page clamping plate 11 to move, a second screw rod 122 for driving the second nut sleeve 121 to move, and an inner page driving motor 123 for driving the second screw rod 122 to rotate, the second nut sleeve 121 is screwed on the second screw rod 122, the second nut sleeve 121 is also fixed to the mounting frame 13, and the second screw rod 122 is connected to the output end of the inner page driving motor 123. The inner page driving motor 123 drives the second screw 122 to rotate, and the rotation of the second screw 122 drives the second nut sleeve 121 to move, thereby driving the inner page clamping plate 11 to move. When the inner page needs to be clamped, the two inner page driving motors 123 synchronously drive the corresponding second screws 122 to move the inner page clamping plates 11 toward each other, thereby completing the clamping of the inner page. When the inner page needs to be released, the two inner page driving motors 123 can rotate in the opposite direction. Compared with the existing ones, the use of electric drive can reduce parts such as chains and sprockets, and the mechanical structure becomes simple and easy to maintain.

[0052] The use of electric drive can reduce the manpower operation and make the operation more convenient. In other embodiments, the cover driver 33 in the first embodiment can also be combined with the inner page clamping mechanism 1 and the gluing mechanism 2 in the first embodiment, or the gluing mechanism 2 and the inner page clamping mechanism 1 in the first embodiment can be combined with the cover driver 33 in the first embodiment, that is, the inner page clamping mechanism 1, the cover driver 33 of the cover clamping mechanism 3 and the gluing mechanism 2 in the first embodiment and the first embodiment can be arbitrarily combined. Generally speaking, when electric drive is used, all drives are usually electric, and when manual drive is used, all drives are manual.

[0053] The rack 4 is also provided with a book taking opening 42 for taking out books. The book taking opening 42 is located at one end of the rack 4 and is arranged opposite to the avoidance opening 41. In this way, the bound books can be taken out from the end of the rack 4, and the taking out is more convenient.

[0054] Embodiment 3

[0055] The difference between this embodiment and the first embodiment is that the bearing plate 32 is passed through the guide column 8 , and the guide column 8 is installed on the frame 4 .

[0056] like Fig.16 and Fig.17As shown, specifically, there are four guide posts 8, which are distributed at the four corners of the bearing plate 32, and the lower ends of the guide posts 8 are bent and fixed on the frame 4; in other embodiments, the guide posts 8 can also be indirectly fixed on the frame 4 or fixed on the frame 4 in other ways. A top plate 3313 is provided on each transmission shaft 3314, and the two top plates 3313 synchronously drive the bearing plate 32 to rise and fall along the guide posts 8, and the bearing plate 32 is always in a horizontal state in this embodiment.
