[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a printing paper alignment mechanism, such as Figure 1-Figure 3 As shown, the alignment mechanism includes a base 1, a positioning plate 2 fixedly mounted on the base 1, a placement table 3 fixedly mounted at a side position of the base 1 corresponding to the positioning plate 2 for aligning the printed paper, and an alignment component 4 arranged at an upper position of the positioning plate 2 corresponding to the placement table 3 for aligning the printed paper left and right; the alignment mechanism also includes a knocking plate 5 which moves longitudinally at a lower position of the base 1 corresponding to the placement table 3, a driving component 6 arranged in the base 1 for driving the knocking plate 5 to move, and buffer members 7 arranged on both sides of the driving component 6.

[0031] When in use, the alignment mechanism is first moved to the output end of the printing paper production equipment, and then the alignment component 4 is adjusted according to the size of the printing paper, and the alignment component 4 can be used for left-right alignment of printing papers of different sizes. Then, the produced printing paper will be directly transmitted from the output end of the production equipment to the placement table 3. The printing paper transmitted to the placement table 3 can be naturally aligned under the limiting action of the positioning plate 2 and the alignment component 4. However, during the natural alignment of the printing paper, the driving component 6 can be started to drive the knocking plate 5 to move longitudinally. At this time, the knocking plate 5 moving longitudinally can vibrate and knock on the bottom of the placement table 3. Through the vibration and knocking of the knocking plate 5, the printing paper naturally aligned on the placement table 3 can further automatically adjust its position to improve the alignment effect of the printing paper.

[0032] Specifically, a receiving groove 11 for accommodating the driving assembly 6 is provided in the base 1; the driving assembly 6 includes a driving shaft 61 rotatably connected in the receiving groove 11 and horizontally passing through the base 1, a rotating wheel 62 rotatably arranged in the receiving groove 11 and fixedly connected to the driving shaft 61, an eccentric shaft 63 fixedly connected to the end of the rotating wheel 62 away from the driving shaft 61, a connecting block 64 fixedly connected to the end of the eccentric shaft 63 away from the rotating wheel 62, a connecting shaft 65 movably connected to the end of the connecting block 64 away from the eccentric shaft 63 and sequentially passing through the receiving groove 11 and the top surface of the base 1, and a speed regulating motor 66 fixedly connected to one side of the base 1 for driving the driving shaft 61 to rotate, the connecting shaft 65 is slidably connected to the base 1, and the end of the connecting shaft 65 away from the connecting block 64 is fixedly connected to the bottom surface of the knocking plate 5; when it is necessary to use the knocking plate 5 to knock on the bottom of the placement table 3, it can be started The speed regulating motor 66 rotates the driving shaft 61. At this time, the driving shaft 61 will synchronously drive the rotating wheel 62 to rotate. Then, under the eccentric connection of the eccentric shaft 63, the connecting block 64 can drive the connecting shaft 65 to move back and forth up and down on the base 1, and the connecting shaft 65 is fixedly connected to the knocking plate 5. Therefore, when the connecting shaft 65 reciprocates up and down, it can synchronously drive the knocking plate 5 to reciprocate up and down, so that the knocking plate 5 can knock the bottom of the placement table 3 back and forth. Among them, when the knocking plate 5 moves downward, the printed paper will be transferred from the output end cup of the production equipment to the placement table 3. When the printed paper is transferred to the placement table 3 and naturally aligned, the knocking plate 5 will knock the placement table 3 upward. However, when using the driving component 6, the frequency of the knocking of the knocking plate 5 can be controlled by adjusting the speed regulating motor 66 to adapt to different production needs.

[0033] Among them, in order to reduce the impact force received by the knocking plate 5, the buffer member 7 is a buffer spring, the buffer spring is movably arranged on the base 1, and the two ends of the buffer spring are respectively fixedly connected to the bottom surface of the knocking plate 5 and the bottom end of the accommodating groove 11; when the knocking plate 5 reciprocates up and down, the arranged buffer spring will also be compressed or stretched with the up and down reciprocating movement of the knocking plate 5. Through the elastic action of the buffer spring, the impact force received by the knocking plate 5 when knocking on the placement table 3 can be reduced, so as to improve the protection of the knocking plate 5.

[0034] Furthermore, the alignment component 4 includes limit plates 41 symmetrically arranged on the placement table 3, sliding blocks 42 respectively fixedly connected to the two limit plates 41 at the upper position on one side close to the positioning plate 2, and cylinders 44 respectively fixedly connected to the two sides of the positioning plate 2 for driving the two sliding blocks 42 to move closer or farther away. The limit plates 41 are slidably connected to the placement table 3; the alignment component 4 also includes a guide rod 43 fixedly connected to the positioning plate 2 and sequentially passing through the two sliding blocks 42, and the sliding blocks 42 are slidably sleeved on the guide rod 43; when the two cylinders 44 are respectively started to push the corresponding two sliding blocks 42, the two sliding blocks 42 can stably drive the two limit plates 41 to move closer or farther from each other under the guiding action of the guide rod 43, so that the left and right positioning of printed papers of different sizes can be adapted by adjusting the spacing between the two limit plates 41.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
