DETAILED DESCRIPTION
[0017] Referring to Figure 1 and 2 , the embodiment of the regular paper for regular printing is described in detail:
[0018] A printing machine paper tray, comprising a support plate 11 and a guide frame 12 fixedly connected to the bottom of the support plate 11, the support plate 11 is used for containing paper, both ends of the guide frame 12 are fixedly connected with cross bars 13, two cross bars 13 are rotatably connected with lead screws 14, the guide frame 12 and the support plate 11 are slidably connected with side plates 21, both sides of the side plates 21 are fixedly connected with transmission sleeves 22 driven by the lead screws 14, the lead screws 14 can rotate around their own axes, when the lead screws 14 rotate, the corresponding two transmission sleeves 22 slide through the screw drive, the two transmission sleeves 22 drive the two side plates 21 to slide on the guide frame 12 and the support plate 11, which can adjust the distance between the two side plates 21, so as to limit the paper of different sizes and realize the regularity of the paper, which is convenient for the flat and stable supply of the paper during printing.
[0019] Referring to Figure 2 , the embodiment of regularizing the paper from both sides of the support plate 11 and preventing the paper from being damaged is described in detail:
[0020] The two side plates 21 are respectively sleeved on both sides of the support plate 11, the sliding of the two side plates 21 can push the paper to be flat, the width of the two side plates 21 is less than the length of the corresponding paper, so as to avoid damaging the corners of the paper when the two side plates 21 slide, and also prevent the paper from being clamped in the gap of the sliding side plate 21 when pushing the paper, causing the paper to be jammed and damaged, and affecting the printing.
[0021] Referring to Figure 2 , the embodiment of driving the two side plates 21 to slide synchronously and reversely to adjust the paper is described in detail:
[0022] The screw rod 14 is opposite in screw direction on both sides, so that when the screw rod 14 rotates, the two transmission sleeves 22 are driven to synchronously slide reversely to adjust the paper.
[0023] With reference to Figure 2 , the embodiment of driving the screw rod 14 to rotate is described in detail.
[0024] One of the two cross rods 13 is fixedly connected with a speed reducer motor I 15 for driving the screw rod 14 to rotate. When the speed reducer motor I 15 is started, the speed reducer motor I 15 drives the screw rod 14 to rotate, so that the two transmission sleeves 22 are driven to synchronously slide reversely to adjust the paper. The number of rotations of the output shaft of the speed reducer motor I 15 in forward and reverse directions can be controlled by the controller, so that the fixed stop position of the two edge plates 21 during movement can be controlled, and the paper is adjusted.
[0025] With reference to Figure 1 and 3 , the embodiment of limiting the paper is described in detail.
