DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4The utility model provides a paper positioning device for book printing, including moving assembly, clamping assembly and bearing assembly, moving assembly includes support plate 1, first motor 2, threaded rod 3 and sliding block 4, the centre of support plate 1 is provided with slide hole, the sliding block 4 is slidably arranged in the slide hole, the threaded rod 3 is also arranged in the slide hole and penetrates the sliding block 4, the output end of first motor 2 penetrates support plate 1 and is connected with threaded rod 3, clamping assembly includes support frame 5, cover 6, worm 7, worm wheel 8, second motor 9, positive and negative tooth screw rod 10 and clamping plate 11, support frame 5 is connected with sliding block 4 below, is provided with positioning groove on support frame 5, is provided with two groups of slide grooves below positioning groove, is provided with cover 6 on one side of support frame 5, is provided with worm 7 and two groups of worm wheel 8 in cover 6, worm 7 is engaged with two groups of worm wheel 8, the output end of second motor 9 penetrates cover 6 and is connected with worm 7, is provided with positive and negative tooth screw rod 10 in slide groove, clamping plate 11 is inverted L shape, is provided with two groups of symmetrical clamping plate 11 on each slide groove, the lower part of clamping plate 11 extends into slide groove and is connected with positive and negative tooth screw rod 10, bearing assembly includes plug 12 and bearing frame 13, is provided with plug 12 below bearing frame 13, the lower part of plug 12 extends into positioning groove, is also provided with the clamping groove of adaptation with clamping plate 11 on plug 12.

[0023] When first motor 2 is started, the output end of first motor 2 drives threaded rod 3 to rotate, and the threaded rod 3 penetrates the sliding block 4, and the sliding block 4 slides in the slide hole in the center of the support plate 1, according to the screw transmission principle, the rotation of the threaded rod 3 will make the sliding block 4 move in the slide hole along the axial direction of the threaded rod 3, and the second motor 9 is started, and the output shaft of the second motor 9 drives the worm 7 to rotate. The worm 7 is engaged with the two groups of worm wheels 8 in the cover 6, and the rotation of the worm 7 drives the worm wheels 8 to rotate synchronously. The worm wheel 8 is connected with the positive and negative tooth screw rod 10, and the rotation of the worm wheel 8 drives the positive and negative tooth screw rod 10 to rotate in the slide groove. Since the lower part of the clamping plate 11 extends into the slide groove and is connected with the positive and negative tooth screw rod 10, when the positive and negative tooth screw rod 10 rotates, according to the screw transmission principle, the two groups of symmetrical clamping plates 11 will move towards or away from each other in the slide groove. In this way, the distance between the clamping plates 11 can be adjusted, so that the plug 12 of the bearing assembly can be clamped or released, and the stable clamping and positioning of the bearing frame 13 are realized.

[0024] The plug 12 below the bearing frame 13 is inserted into the positioning groove on the support frame 5, which provides preliminary positioning for the bearing frame 13. The clamping groove on the plug 12 is matched with the clamping plate 11 of the clamping assembly, when the clamping plate 11 moves towards each other under the drive of the positive and negative tooth screw rod 10, the clamping plate 11 will be embedded in the clamping groove, tightly clamping the plug 12, so as to fix the position of the bearing frame 13, and ensure that the bearing frame 13 remains stable during the printing process. The bearing frame 13 is used to place the paper required for book printing;

[0025] The load frame 13 provides a bearing platform for paper, and the supporting legs 14 are arranged at the four corners below the part of the supporting frame 5, and can support the load frame 13 after the load frame 13 is detached from the supporting frame 5. The supporting legs 14 are flush with the lower part of the insertion block 12, which can ensure that the load frame 13 is placed stably. The lower part of the supporting legs 14 is provided with a rounded part 15, which can prevent the supporting legs 14 from scratching the placing surface and also avoid scratching the personnel in the operation process.

[0026] The first motor 2 and the second motor 9 are both servo motors, which have precise control performance and can accurately control the rotation angle and speed of the threaded rod 3 and the positive and negative toothed screw rod 10. This can accurately control the movement of the sliding block 4 and the opening and closing of the clamping plate 11, and then realize the precise positioning and stable clamping of the load frame 13, which can ensure the position accuracy of the book paper in the printing process and improve the printing quality.

[0027] The wide opening 16 arranged in the clamping groove opening part can guide the installation of the load frame 13. The insertion block 12 is easier to align and insert into the clamping groove, which reduces the operation difficulty and improves the efficiency of installing the load frame 13.
