Detailed implementation mode

[0028] The present utility model will be further described below with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] Please refer to Figure 1 , the spine clamping structure of the present utility model is used to be installed on the operating table of a bookbinding machine to clamp the book pages and the cover to form a spine. It includes two clamping plates for clamping the book pages, a guiding unit for defining the moving directions of the two clamping plates, and a driving mechanism 5 for driving the two clamping plates to open and close. The two clamping plates are arranged on the upper end surface of the operating table 6 for clamping the book pages and the cover, the guiding unit is arranged between the clamping plates and the operating table 6, and the driving mechanism 5 is arranged on the lower end surface of the operating table 6 to cooperate with the guiding unit to realize the opening and closing movement of the two clamping plates.

[0031] Please refer to Figure 2, for ease of description, the two clamping plates are respectively defined as a first clamping plate 1 and a second clamping plate 2. The first clamping plate 1 and the second clamping plate 2 are symmetrically arranged and the long sides of the first clamping plate 1 and the second clamping plate 2 are opposite to each other. The first clamping plate 1 has a first abutting surface 11. Specifically, the side surface of the first clamping plate 1 close to the second clamping plate 2 is the first abutting surface 11, and the first abutting surface 11 is a vertical surface. The first clamping plate 1 is also processed with a first inclined surface 12. One side of the first inclined surface 12 is connected to the upper end surface of the first clamping plate 1, and the other side is connected to the first abutting surface 11. The first inclined surface 12 gradually decreases from the upper end surface of the first clamping plate 1 to the first abutting surface 11. The first clamping plate 1 is provided with a first cavity 13 penetrating along its own length. The second clamping plate 2 has a second abutting surface 21. Specifically, the side surface of the second clamping plate 2 close to the first clamping plate 1 is the second abutting surface 21, and the second abutting surface 21 is a vertical surface. In this way, the second abutting surface 21 and the first abutting surface 11 cooperate to clamp the book pages and the cover into an appropriate spine shape. The second clamping plate 2 is also processed with a second inclined surface 22. One side of the second inclined surface 22 is connected to the upper end surface of the second clamping plate 2, and the other side is connected to the second abutting surface 21. The second inclined surface 22 gradually decreases from the upper end surface of the second clamping plate 2 to the second abutting surface 21. The second clamping plate 2 is provided with a second cavity 23 penetrating along its own length. The settings of the first cavity 13 and the second cavity 23 reduce the materials required for processing the first clamping plate 1 and the second clamping plate 2, and reduce the processing cost.

[0032] Please refer to Figure 3 , Figure 4 and Figure 5, there are two sets of the orientation units. For the convenience of description, the two sets of orientation units are respectively defined as the first orientation unit 3 and the second orientation unit 4. The first orientation unit 3 and the second orientation unit 4 are symmetrically arranged at both ends of the first clamping plate 1 and the second clamping plate 2 in the length direction. The first orientation unit 3 includes two first sliders 31 and a first chute 32 opened on the operation table 6. The first chute 32 is opened along the opening and closing direction of the first clamping plate 1 and the second clamping plate 2 (that is, the first chute 32 is opened along the width direction of the first clamping plate 1 and the second clamping plate 2) and vertically penetrates the operation table 6. Each of the first sliders 31 includes a first part 311 and a second part 312 arranged at the lower end of the first part 311. One of the first sliders 31 is installed on the lower end surface of the first clamping plate 1 and this first slider 31 is arranged along the width direction of the first clamping plate 1. The first part 311 of this first slider 31 is fixedly connected to the lower end surface of the first clamping plate 1, and the width of the first part 311 is the same as the width of the first chute 32 to be slidably arranged in the first chute 32. The width of the second part 312 is greater than the width of the first part 311 and the upper end surface of the second part 312 contacts the lower end surface of the operation table 6, so that the first clamping plate 1 will not generate displacement in the vertical direction. The other first slider 31 is installed on the lower end surface of the second clamping plate 2 and this slider is arranged along the width direction of the second clamping plate 2. The first part 311 of this first slider 31 is fixedly connected to the lower end surface of the second clamping plate 2, and the width of the first part 311 is the same as the width of the first chute 32 to be slidably arranged in the first chute 32. The width of the second part 312 is greater than the width of the first part 311 and the upper end surface of the second part 312 contacts the lower end surface of the operation table 6, so that the second clamping plate 2 will not generate displacement in the vertical direction.

[0033] The second orientation unit 4 includes two second sliders 41 and a second chute 42 opened on the operation table 6. The second chute 42 is arranged in the same way as the first chute 32. The structures of the two second sliders 41 are the same as the structures of the two first sliders 31. The assembly relationship between the second slider 41 and the second chute 42 is also the same as the assembly relationship between the first slider 31 and the first chute 32, so it will not be elaborated here.

[0034] Please refer to Figures 4 to 7, the driving mechanism 5 includes two first link rods 51, two second link rods 52 and a driving part, and the driving part is used to connect with the two first link rods 51 to drive the ends of the two first link rods 51 to open and close. The two first link rods 51 are located at one end in the length direction of the first clamping plate 1 and the second clamping plate 2. Specifically, they are arranged corresponding to the first orientation unit 3. One end of each of the two first link rods 51 serves as a first pivoting end and is pivotally connected to the first clamping plate 1 and the second clamping plate 2 respectively. Specifically, the two first link rods 51 are pivotally connected to the first clamping plate 1 and the second clamping plate 2 through the two first sliding platforms 31, that is, the two first link rods 51 are respectively rotatably connected to the two first sliding platforms 31, and the two first link rods 51 are respectively rotatably connected to the ends of the two first sliding platforms 31 that are away from each other. The connection method is as follows: first pivot holes 511 are provided in the vertical direction at the first pivoting ends of the two first link rods 51, and a first pivot shaft 512 is rotatably connected in each first pivot hole 511. The upper ends of the two first pivot shafts 512 are respectively fixedly connected to the lower end surfaces of the two first sliding platforms 31. The other ends of the two first link rods 51 are both configured as second pivoting ends, and a second pivot hole 513 is respectively provided in the two second pivoting ends. A second pivot shaft 514 is commonly passed through the two second pivot holes 513, and the second pivot shaft 514 is rotatably connected to both of the two second pivot holes 513.

[0035] The two second link rods 52 are located at the other end in the length direction of the first clamping plate 1 and the second clamping plate 2. Specifically, they are arranged corresponding to the second orientation unit 4. One end of each of the two second link rods 52 serves as a fourth pivoting end and is pivotally connected to the first clamping plate 1 and the second clamping plate 2 respectively. Specifically, the two second link rods 52 are pivotally connected to the first clamping plate 1 and the second clamping plate 2 through the two second sliding platforms 41, that is, the two second link rods 52 are respectively rotatably connected to the two second sliding platforms 41, and the two second link rods 52 are respectively rotatably connected to the ends of the two second sliding platforms 41 that are away from each other. The connection method is as follows: third pivot holes 521 are provided in the vertical direction at the fourth pivoting ends of the two second link rods 52, and a third pivot shaft 522 is rotatably connected in each third pivot hole 521. The two third pivot shafts 522 are respectively fixedly connected to the lower end surfaces of the two second sliding platforms 41. The other ends of the two second link rods 52 are both configured as fifth pivoting ends, and a fourth pivot hole 523 is respectively provided in the two fifth pivoting ends. A fourth pivot shaft 524 is commonly passed through the two fourth pivot holes 523, and the fourth pivot shaft 524 is rotatably connected to both of the two fourth pivot holes 523.

[0036] The two sets of orientation units symmetrically arranged, as well as the first link 51 and the second link 52, make the force on the first clamping plate 1 and the second clamping plate 2 more uniform, and make the movement of the first clamping plate 1 and the second clamping plate 2 more stable.

[0037] The driving part includes a driving rod 53a. One end of the driving rod 53a is configured as a third pivoting end that is pivotally connected to both of the second pivoting ends. A guiding groove 531 is vertically and penetratingly formed in the third pivoting end. The guiding groove 531 is elongated and has a width matching the diameter of the second pivot 514. The lower end of the second pivot 514 extends out of the two second pivot holes 513 and extends into the guiding groove 531. The second pivot 514 can slide along the length direction of the guiding groove 531 in the guiding groove 531. A rotating shaft 532 is provided on the lower end surface of the operating table 6. A rotating hole 533 is provided at the middle section of the driving rod 53a corresponding to the position of the rotating shaft 532. The rotating hole 533 is sleeved outside the rotating shaft 532 to use it as a lever fulcrum. One end of the driving rod 53a far from the third pivoting end is defined as a holding end 534. The holding end 534 forms an angle greater than ninety degrees on the horizontal plane with the middle section, so that it is more convenient for the user to apply force to the driving rod 53a through the holding end 534.

[0038] The driving mechanism 5 further includes a linkage rod 535. The linkage rod 535 is used to link the two first links 51 and the two second links 52, that is, transfer the power brought by the driving rod 53a to the two first links 51 to the two second links 52. The linkage rod 535 is arranged along the length direction of the first clamping plate 1 and the second clamping plate 2. The lower end of the second pivot 514 extends out of the guiding groove 531 and is fixedly connected to the linkage rod 535. The lower end of the fourth pivot 524 extends out of the two fourth pivot holes 523 and is fixedly connected to the linkage rod 535.

[0039] The working mode of the first embodiment of the spine clamping structure of the present invention is as follows: In the initial state, the third pivoting end of the driving rod 53a is located at the position farthest from the first pivoting ends of the two first links 51 in its own stroke. At this time, both of the two first links 51 form a certain inclination angle with the length direction of the first clamping plate 1 and the second clamping plate 2.

[0040] When processing the book pages, move the driving rod 53a, so that the third pivoting end of the driving rod 53a moves towards the direction close to the first pivoting ends of the two first connecting rods 51. At this time, the first pivoting ends of the two first connecting rods 51 will move away from each other, driving the two first sliding platforms 31 to move away from each other. At the same time, the movement of the first pivoting end drives the fourth pivoting end to move in the same direction through the linkage rod 535, so that the fourth pivoting ends of the two second connecting rods 52 will move away from each other. In such a case, the first clamping plate 1 and the second clamping plate 2 will move away from each other, and a gap will appear between the first clamping plate 1 and the second clamping plate 2.

[0041] Lay the cover flat on the first clamping plate 1 and the second clamping plate 2, adjust the position of the cover to be appropriate, place the book pages to be processed on the cover and press down the cover, so that a part of the book pages and a part of the cover move down into the gap between the first clamping plate 1 and the second clamping plate 2. At this time, move the driving rod 53a in the opposite direction to the above. At this time, the two first pivoting ends move towards each other, and the two fourth pivoting ends also move towards each other, so that the first clamping plate 1 and the second clamping plate 2 move towards each other to clamp the book pages and the cover and squeeze them to form a spine. The settings of the first inclined surface 12 and the second inclined surface 22 can provide a supporting and protecting effect on the cover. The first inclined surface 12 provides a transition between the first abutting surface 11 and the upper end surface of the first clamping plate 1. The connection between the first inclined surface 12 and the first abutting surface 11 and the connection between the first inclined surface 12 and the upper end surface of the first clamping plate 1 can provide a two-stage support for the cover. The same is true for the second inclined surface 22.

[0042] After the processing is completed, move the driving rod 53a to make the first clamping plate 1 and the second clamping plate 2 move away from each other, and then take out the processed book.

[0043] Embodiment 2:

[0044] This embodiment has the first clamping plate 1, the second clamping plate 2, the positioning unit, the first connecting rod 51, the second connecting rod 52, the first pivot 512, the second pivot 514, the third pivot 522 and the fourth pivot 524 which have the same structures and functions as those in Embodiment 1. Please refer to Figure 8, in this embodiment, the driving part includes a driving rod 53b, a plurality of convex teeth 54, a rotating rod 55 and a gear 56. The driving rod 53b is arranged along the length direction of the first clamping plate 1 and the second clamping plate 2. One end of the driving rod 53b is configured as a third pivoting end that is pivotally connected to the second pivoting ends of the two first connecting rods 51, and the third pivoting end is fixedly connected to the lower end of the second pivot shaft 514. One end of the driving rod 53b far from the third pivoting end is defined as a sixth pivoting end, and the sixth pivoting end is fixedly connected to the lower end of the fourth pivot shaft 524. A plurality of the convex teeth 54 are all arranged on the lower end surface of the driving rod 53b, and a plurality of the convex teeth 54 are evenly spaced along the length direction of the driving rod 53b. The rotating rod 55 is arranged along the width direction of the driving rod 53b, and the rotating rod 55 is rotatably arranged at a position corresponding to the lower part of the driving rod 53b on the operating table 6. A gear 56 is provided at a position corresponding to the driving rod 53b on the rotating rod 55 (that is, at the position where the rotating rod 55 and the driving rod 53b intersect on the horizontal projection plane), and the gear 56 is meshed and matched with a plurality of the convex teeth 54.

[0045] The working mode of the second embodiment of the book spine clamping structure of the present utility model is as follows: In the initial state, the third pivoting end of the driving rod 53b is located at the position farthest from the first pivoting ends of the two first connecting rods 51 in its own stroke. At this time, both of the two first connecting rods 51 form a certain inclination angle with the length direction of the first clamping plate 1 and the second clamping plate 2.

[0046] When the book pages need to be processed, rotate the rotating rod 55 to drive the gear 56 to rotate. The rotation of the gear 56 drives the driving rod 53b to move along the length direction of the first clamping plate 1 and the second clamping plate 2 through a plurality of the convex teeth 54 that are meshed therewith, so as to drive the first pivoting ends of the two first connecting rods 51 to move in the same direction. During this process, the two first sliding platforms 31 move towards or away from each other, and the two second sliding platforms 41 also move towards or away from each other. In such a case, the first clamping plate 1 and the second clamping plate 2 will move towards or away from each other.
