DETAILED DESCRIPTION

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

[0036] Example 1

[0037] like Figure 1 and Figure 2As shown, a preferred embodiment of the small glue binding machine of the present invention includes an inner page clamping mechanism 1 for clamping inner pages, a gluing mechanism 2 for gluing the inner pages, a cover clamping mechanism 3 for gluing the cover and the inner pages, and a frame 4 for mounting 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 mounted 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 mounted on the frame 4 via 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 or unused state, the telescopic rail 5 is in a retracted state. When the telescopic rail 5 is in the retracted state, the inner page clamping mechanism 1 is located above the cover clamping mechanism 3. During binding, the inner page clamping mechanism 1 moves horizontally, and the telescopic rail 5 gradually expands. When the inner page clamping mechanism 1 passes 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 retracts 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 of the inner page. The cover is then placed on the cover clamping mechanism 3, and the cover and inner page are glued together using the cover clamping mechanism 3. Two telescopic rails 5 are usually used to facilitate the stability of the inner page clamping mechanism 1 during movement. The use of a telescopic rail 5 can reduce the rail length, 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 does not deflect or skew when it is expanded or retracted. It should be noted that the telescopic rail 5 can also be installed on only one side; the telescopic rail 5 is a common component in daily life. The cross-section of the telescopic rail 5 is generally C-shaped and can be a two-stage or three-stage type. Those skilled in the art are familiar with the telescopic structure and principle, and the specific telescopic structure and principle are not detailed here.

[0038] The inner page clamping mechanism 1 is provided with a movable handle 6, which facilitates the movement of the inner page clamping mechanism 1 by pushing the movable handle 6; the movable handle 6 is provided vertically, which is convenient for gripping without interfering with other components. In other embodiments, it is also possible not to provide a movable 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 an existing manual inner page clamping mechanism 1, and the use of a 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, 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 binding 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, providing more glue on the inner pages and thus improving the binding effect. The paging function can be added as needed.

[0041] In order to reduce the number of parts, a linkage assembly 7 is provided for the linkage of 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 glue 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 provided 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 mounted on the rotating shaft 23. The linkage rack 73 is fixed on the inner page clamping mechanism 1. The intermediate gear 72 is engaged 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. The movement of the linkage rack 73 drives the intermediate gear 72 to rotate. The rotation of the intermediate gear 72 drives the linkage gear 71 to rotate. The rotation of the linkage gear 71 drives the rotation of the rotating shaft 23. The rotation of the rotating shaft 23 drives the rubber roller 22 to rotate, so that the rubber roller 22 is always attached with glue, 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. This ensures 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.

[0042] like Figures 5 to 8As shown, the cover clamping mechanism 3 includes two cover clamps 31 for clamping the cover, a carrier plate 32 for supporting the cover clamps 31, and a cover actuator 33 for lifting the carrier plate 32 and driving the two cover clamps 31 on the carrier plate 32. One side of the carrier plate 32 is hinged to the frame 4. The carrier plate 32 is initially tilted to avoid the movement of the inner pages by the inner page clamping mechanism 1. When the carrier plate 32 is raised to a horizontal position by the cover actuator 33, the cover and inner pages are attached. The carrier plate 32 is provided with two sets of slide grooves 321, and the cover clamps 31 slide in the corresponding set of these 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 corresponding to 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 clamp 31, and each transmission shaft 3314 is installed with a transmission gear 3315 and two said shift rods 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, which 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 lift the supporting plate 32 to a horizontal state, and then the transmission shaft 3314 drives the shift rod 3311 to contact the transmission member 34 of the cover clamp 31 to drive the two cover clamps 31 to move on the supporting plate 32. The handle 3316 is fixed to 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 to another transmission shaft 3314. The reset member 3312 is generally a spring, but 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 to the support plate 32. The two transmission shafts 3314 rotate synchronously in the forward and reverse directions, so that the two cover clamps 31 move in opposite directions.

[0044] like Figure 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 provided on the transmission member 34. 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, which rolls on the top plate 3313 to reduce friction. Figure 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 the gluing position, and the distance between any position of the walking surface 33132 and the rotating shaft 23 is the same, 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, with the surface formed by the thickness of the top plate 3313 serving as a side wall. The curved side wall of the top plate 3313 serves as a running surface 33132. A recess is provided on the linear side wall of the top plate 3313, forming a positioning notch 33131. To prevent the roller 35 from entering another linear side wall from the running surface 33132, the length of the running surface 33132 is greater than the movable length of the cover clamp 31 within the slide slot 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, the inner page is first clamped on the inner page clamping mechanism 1, and then the movable handle 6 is pushed back and forth so that the inner page is glued by the glue roller 22, and then the cover is placed on the carrier plate 32. The cover can also be placed on the carrier plate 32 when clamping the inner page; then the driving handle 3316 is rotated, and the driving handle 3316 drives the transmission shaft 3314 to rotate, so that the carrier plate 32 is first rotated to the horizontal. When the carrier plate 32 is rotated to the horizontal, the cover and the glued surface of the inner page are in contact, 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 rail. When not in use, it can save length without increasing width, reducing the occupied space.

[0047] Example 2

[0048] like Figure 11As shown, this embodiment differs 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 holding glue, a rubber roller 22 for applying glue to the inner pages, and a rotating shaft 23 for mounting the rubber roller 22. The rotating shaft 23 is rotatably mounted 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. 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 rotation of the rubber roller motor 24 drives the rotating shaft 23, which simultaneously drives the rubber roller 22 and the linkage gear 71. The rotation of the linkage gear 71 drives the rotation of the intermediate gear 72. The rotation of the intermediate gear 72 drives the linkage rack 73 to move. The movement of the linkage rack 73 drives the inner page clamping mechanism 1 to move. This achieves a single power device to simultaneously drive the rubber roller 22 and the inner page clamping mechanism 1.

[0050] The cover driver 33 includes two first nut sleeves 3321 for driving the corresponding transmission members 34, a first screw 3322 that simultaneously drives the two first nut sleeves 3321 to move toward or in opposite directions, a first drive motor 3323 for rotating the first screw sleeves 322, a drive wheel 3324 for lifting the carrier plate 32, and a second drive motor 3325 for driving the drive wheel 3324 to eccentrically rotate. The first drive motor 3323 can be mounted on the carrier plate 32. The first screw 3322 is connected to the output end of the first drive motor 3323. The first screw 3322 has two oppositely spiral threaded sections. The two first nut sleeves 3321 are respectively screwed onto different threaded sections of the first screw 3322. The first nut sleeves 3321 are also fixed to the corresponding transmission member 34, which 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 clamps 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 it from a horizontal state to an inclined state. The use of electric drive can reduce components such as transmission shafts and synchronous gears, making the mechanical structure simpler and easier to maintain.

[0051] The inner page clamping mechanism 1 includes an inner page clamping plate 11 for clamping the inner page, 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 bracket 13 for installing the electric driver. The inner page electric driver 12 includes two drive components 120, each drive component 120 corresponds to an inner page clamping plate 11, and the drive component 120 is used to drive the inner page clamping plate 11. Each drive 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 drive 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 bracket 13, and the second screw rod 122 is connected to the output end of the inner page drive motor 123. The inner page drive 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 drive motors 123 synchronously drive the corresponding second screw 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 drive motors 123 can rotate in opposite directions. Compared with the existing ones, the use of electric drive can reduce components such as chains and sprockets, and the mechanical structure becomes simpler and easier to maintain.

[0052] The use of electric drive can reduce manpower and make operation more convenient. In other embodiments, the cover drive 33 of the first embodiment can be combined with the inner page clamping mechanism 1 and the gluing mechanism 2 of this embodiment, or the gluing mechanism 2 and the inner page clamping mechanism 1 of the first embodiment can be combined with the cover drive 33 of this embodiment. That is, the inner page clamping mechanism 1, the cover drive 33 of the cover clamping mechanism 3, and the gluing mechanism 2 of this embodiment and the first embodiment can be combined in any way. 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 further 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, which is more convenient.

[0054] Example 3

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

[0056] like Figure 16 and Figure 17As shown, specifically, there are four guide posts 8, which are distributed at the four corners of the support plate 32. The lower ends of the guide posts 8 are bent and fixed to the frame 4. In other embodiments, the guide posts 8 can also be indirectly fixed to the frame 4 or fixed to the frame 4 in other ways. A top plate 3313 is provided on each transmission shaft 3314. The two top plates 3313 synchronously drive the support plate 32 to rise and fall along the guide posts 8. The support plate 32 is always in a horizontal state in this embodiment. It should be known that this embodiment can also be applied to the second embodiment, such as Figure 18 As shown, two second drive motors 3325 and drive wheels 3324 are used, one drive wheel 3324 corresponds to one second drive motor 3325, and the two drive wheels 3324 are distributed at both ends of the supporting plate 32. Of course, in other embodiments, they can also be distributed on both sides of the supporting plate 32.

[0057] The above is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
