[0029] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0030] See also Figure 1 , Figure 2 As shown, the present invention provides a plate rib positioning and dotting device, comprising: two rollers 1 arranged in parallel, the middle parts of the two rollers 1 are connected by a synchronous shaft 11; a positioning plate 2, coaxially fixed on the synchronous shaft 11; an ink sac 21, fixed on the positioning plate 2, an ink supply tube 22 is provided on the ink sac 2, a first end of the ink supply tube 22 is connected to the ink sac 22, and a dotting portion 23 is connected to the second end of the ink supply tube 22; a swing arm 24, a first end of the swing arm 24 is hinged on the positioning plate 2, and the dotting portion 23 connected to the ink supply tube 22 is fixed on the second end of the swing arm 24, the outer edge of the dotting portion 23 coincides with the circumference of the roller 1, and limit plates 25 for limiting the swing amplitude of the swing arm 24 are respectively provided on opposite sides of the first end of the swing arm 24 on the positioning plate 2.

[0031] In the embodiment of the present invention, the circumference of the roller 1 is twice the spacing between the plate ribs, and the corresponding number of the swing arms 24 is two, and the two swing arms 24 are centrally symmetrical. Generally, the spacing between the plate ribs is 10 to 20 centimeters, and two can basically meet the requirements; when the circumference of the roller 1 is three times the spacing between the plate ribs, the number of the swing arms 24 is 3, which are evenly spaced on the positioning plate 2, and the circumference of the roller 1 and the number of the swing arms 24 are set accordingly; preferably, the roller 1 is a rubber roller to prevent the roller 1 from slipping during the advancement process and affecting the accuracy of the dot position.

[0032] Preferably, a dotting position mark A is also provided on the roller 1. When the roller 1 rotates to the position of the dotting position mark A, the dotting part 23 performs dotting. The setting of the dotting position mark A can play a role in identification and correction, so that inaccurate dotting positions can be discovered in time; preferably, a starting point mark B is also provided at a position 5 cm away from the dotting position mark A. When in use, the lifting mark B is aligned with the edge of the beam and the dotting is performed at a uniform speed in a straight line direction. This can ensure that the starting point of the dotting device's travel route is the same each time, thereby improving the accuracy of the dotting position.

[0033] like Figure 2 As shown, the axial direction of the synchronization shaft 11 is provided with a convex strip 111, and the inside of the roller 1 is formed with a groove that matches the convex strip 111. By setting the convex strip 111 to engage with the groove inside the roller 1, the synchronization shaft 11 can rotate synchronously with the roller 1, so that the rotation radius of the roller 1 is the same as the rotation radius of the dotting portion 23.

[0034] In the embodiment of the present invention, the ink bag 22 contains ink, and the color of the ink is adjusted according to the color of the template.

[0035] In the embodiment of the present invention, the dotting portion 23 is a sponge strip, and the second end of the swing arm 24 is provided with a first receiving groove for embedding the sponge strip, and the sponge strip partially extends out of the receiving groove so as to contact with the template surface for dotting, and the second end of the swing arm 24 is also provided with a second receiving groove for the ink delivery tube 22 to pass through, and the second receiving groove is connected to the first receiving groove. Furthermore, a receiving frame for wrapping the sponge strip is also embedded in the first receiving groove.

[0036] In an embodiment of the present invention, the swing arm 24 is an arc-shaped swing arm, and the arc-shaped concave surface of the swing arm 24 is arranged toward the positioning plate 2; the shape of the swing arm 24 is not limited to an arc-shaped swing arm, and can also be a linear swing arm. The setting of the swing arm 24 is based on the rotation radius during the rotation process being the same as the rotation radius of the dotting part 23.

[0037] Preferably, in order to adjust the swing amplitude of the swing arm 24 so that the rotation radius of the swing arm 24 is adjustable, thereby being applicable to the dotting of plate ribs with different spacings, the limit plate 25 is configured as a position-adjustable limit plate 25; specifically, a bolt (not shown) is fixed on the limit plate 25, and a plurality of adjustment holes for the bolts to pass through are respectively opened on the positioning plate 2 on opposite sides of the first end of the swing arm 24.

[0038] In the embodiment of the present invention, in order to conveniently control the rolling of the roller 1, a connecting rod 3, a cross beam 31 and a handle 32 for controlling the rolling of the roller 1 are also provided; specifically, the two ends of the synchronization shaft 11 respectively pass through the middle of the two rollers 1, and the two ends of the synchronization shaft 11 are respectively movably connected with the connecting rod 3 located on the outside of the roller 1, and a cross beam 31 is connected between the two connecting rods 3, and a handle 32 is fixed on the cross beam 31. The setting of the handle 32 can make the rotation of the roller 1 more convenient and improve the user's comfort. Preferably, the handle 32 can be set as a telescopic handle with adjustable length according to the height of the user.

[0039] Preferably, if Figure 3 As shown, the first end of the connecting rod 3 is detachably connected to the synchronization shaft 11, and the second end of the connecting rod 3 is fixed to the crossbeam 31; specifically, the first end of the connecting rod 31 is a clamp structure, and the first end of the connecting rod 31 can be easily separated from the end of the synchronization shaft 11 through the setting of the clamp structure, so as to facilitate the replacement of rollers 1 of different directions.

[0040] The structure of the plate reinforcement positioning and dotting device of the present invention is specifically described above, and its working principle is described below.

[0041] like Figure 4 As shown, the circumference of the roller 1 is a fixed value, which is twice the plate rib spacing, and the dotting device is symmetrically arranged with the dotting portion 23 at the upper and lower centers. Figure 4 As shown in the middle right figure, when the dotting part 23 rolls downward and is acted upon by gravity, the swing arm hangs downward, and the dotting part 23 below contacts the template surface to dot, and continues to move along the horizontal arrow. Figure 4 In the middle left figure, the upper dotting portion 23 rolls to contact the template surface to dot, and reciprocates to leave marking points on the template surface.
