DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0017] like Figure 1-2 A carton printing deviation correction device shown in the figure comprises a plurality of rollers 1 arranged evenly for conveying cartons, support members are installed at both ends of the rollers 1, upright plates 2 extending upward are arranged on the support members, a top plate 3 is connected between the top ends of the upright plates 2 on both sides of the rollers 1, the top plate 3 is made of a transparent material, the top plate 3 is located above the rollers 1, a plurality of groups of deviation correction mechanisms are symmetrically installed at the bottom of the top plate 3, and the bottom ends of the plurality of groups of deviation correction mechanisms are sequentially inserted between two adjacent rollers 1;

[0018] During operation, the cartons are transported along a plurality of rollers 1, and the correction mechanism on the top plate 3 corrects and adjusts the direction of the cartons. The top plate 3 made of transparent material does not affect the observation of the direction of the carton from above, thereby obtaining the actual effect of the carton correction.

[0019] The support member includes a shaft 4 connected to the end of the roller shaft 1, a first bearing 5 is sleeved on the other end of the shaft 4, a support frame 6 is fixedly sleeved outside the first bearing 5, a bottom plate 7 is installed at the bottom end of the support frame 6, and the bottom end of the vertical plate 2 is fixed on the bottom plate 7;

[0020] Both ends of the roller shaft 1 are installed on the support frame 6 through the shaft rod 4 and the first bearing 5. The roller shaft 1 and the shaft rod 4 rotate on the first bearing 5, and the support frame 6 and the bottom plate 7 play a supporting role.

[0021] A positioning plate 8 extending downward is installed in the middle of the bottom surface of the top plate 3, and a plurality of sets of deviation correction mechanisms are connected between the positioning plate 8 and the vertical plate 2 and are symmetrically arranged through the positioning plate 8;

[0022] The positioning plate 8 acts as a dividing line at the bottom of the top plate 3. Several groups of correcting mechanisms are located on both sides of the positioning plate 8 and are symmetrically arranged through the positioning plate 8 so that the correcting mechanisms on both sides can adjust the two sides of the carton during transportation to change the angle of transportation on the roller 1.

[0023] The deviation correction mechanism includes a second bearing 9 fixed on the outer walls of both sides of the positioning plate 8 and a rotating shaft 10 passing through the vertical plate 2, one end of the rotating shaft 10 is inserted into the second bearing 9 and the other end extends to the outside of the vertical plate 2, and a knob 11 is installed at the end of the rotating shaft 10 located on the outside of the vertical plate 2;

[0024] A thread is provided on the outer wall of the rotating shaft 10, and a threaded tube 12 matching the thread is sleeved on the outside of the rotating shaft 10, and a downwardly extending correction rod 13 is installed at the bottom end of the threaded tube 12, and the bottom end of the correction rod 13 extends between two adjacent rollers 1, and a rotating sleeve 14 is sleeved on the outside of the lower half of the correction rod 13;

[0025] A connecting rod 15 is fixed to the top of the threaded tube 12 . The connecting rod 15 extends upward, and a limiting plate 16 that fits with the top plate 3 is installed on the top of the connecting rod 15 .

[0026] On the basis of the above, several groups of deviation correction mechanisms are symmetrically arranged through the positioning plate 8. When the user turns the knob 11, the rotating shaft 10 will be driven to rotate on the second bearing 9 and the vertical plate 2. The outer wall of the rotating shaft 10 has threads adapted to the threaded tube 12. The threaded tube 12 is limited by the connecting rod 15 and the limiting plate 16. When the rotating shaft 10 rotates, the threaded tube 12 will be driven by the threads to slide left and right along the extension direction of the rotating shaft 10. The directional movement of the threaded tube 12 and the deviation correction rod 13 can be achieved by controlling the rotation direction of the rotating shaft 10.

[0027] Furthermore, several groups of correcting mechanisms are arranged along the extension direction of the roller 1, and the positions of the threaded tube 12 and the correcting rod 13 in each correcting mechanism are adjusted in turn by the knob 11, and the position of the correcting rod 13 on the roller 1 is adjusted so that the correcting rods 13 in several groups of correcting mechanisms form a path to correct and adjust the carton.

[0028] Among them, after the position of the deflection correction rod 13 is adjusted, the distance between the deflection correction rods 13 on both sides of the upstream conveying direction of the roller 1 is the largest, and then the distance between the deflection correction rods 13 in the downstream direction is gradually reduced until it is the same as the width of the carton;

[0029] Furthermore, a rotating sleeve 14 is provided on the outside of the correcting rod 13. When the carton is transported on the roller 1, it will fit with the sleeve 14 on the outside of the correcting rod 13. The rotation of the sleeve 14 can achieve a direction adjustment and correction effect, so that the carton can achieve directional correction adjustment along the correcting rod 13 and the sleeve 14 arranged in sequence.

[0030] On the basis of the above, the deflection correction rod 13 and the sleeve 14 are used so that the bottom ends of the deflection correction rod 13 and the sleeve 14 can be inserted into the area between two adjacent rollers 1, and the bottom ends of the deflection correction rod 13 and the sleeve 14 are lower than the top of the roller 1, so that the deflection correction rod 13 and the sleeve 14 can completely fit with the surface of the carton when correcting the carton, thereby improving the effect of correction and angle adjustment, and the deflection correction rod 13 symmetrically arranged on both sides and freely adjustable can be suitable for cartons of various sizes and specifications for correction, thereby improving practicality.

[0031] Furthermore, the adjustment method of the knob 11 and the rotating shaft 10 can realize the size adjustment of the correction mechanism without stopping the equipment during operation, thereby improving practicality.
