[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] See also Figures 1-7 As shown, the present invention provides a visual deviation correction device for a dough roll. The main function of the forming and correcting machine 8 is to perform a series of operations such as feeding, position correction, detection, and folding and bending the dough roll to ensure that the dough roll reaches the required shape and position accuracy. The forming and correcting machine 8 includes a forming and correcting frame and a third chain transmission mechanism inside thereof for realizing the tilting and lifting of the dough roll from bottom to top. A dough roll feeding structure for feeding the dough roll is provided on one side of the bottom of the third chain transmission mechanism. A transition roller 806 is provided between the third chain transmission mechanism and the straightening belt 9. The function of the transition roller 806 is to smoothly transition the dough roll on the third chain transmission mechanism to the straightening belt 9 to ensure the continuity of the dough roll conveying. The third chain transmission mechanism is provided with a correction mechanism for correcting the position of the dough roll, and the forming correction frame is provided with a visual camera 805 for detecting the dough roll on the third chain transmission mechanism. The visual camera 805 is installed on the forming correction frame and is used to detect the dough roll on the third chain transmission mechanism. The visual camera 805 can detect the position, shape and other parameters of the dough roll and provide feedback information for the subsequent correction mechanism operation. A shifting claw assembly for realizing the folding and bending of the dough roll is provided above the transition roller 806.

[0032] The dough roll feeding structure includes a roller 813, one end of which is driven to rotate by a sixth motor 811 fixedly arranged on the forming correction frame. A plurality of groups of transition claws 808 are evenly distributed around the axis of the roller 813, and each group includes a plurality of transition claws 808 evenly distributed along the axial direction of the roller 813. When the roller 813 rotates, the transition claws 808 grab the dough roll and convey it to the dough roll lifting hanging plate 803 of the third chain transmission mechanism, thereby feeding the third chain transmission mechanism. The first gap groove 812 on the dough roll lifting hanging plate 803 matches the transition claws 808 one by one, so that the transition claws 808 can accurately place the dough roll on the dough roll lifting hanging plate 803.

[0033] There are two third chain drive mechanisms arranged in parallel. The third chain drive mechanism includes two third sprockets 801. A third chain 802 is meshed and drivingly connected between the two third sprockets 801. A number of chain follower plates 826 are evenly distributed between the two third chains 802 along their driving direction. A surface roll lifting hanging plate 803 capable of axially moving and adjusting along the third sprocket 801 under the drive of a correction mechanism is arranged on the chain follower plate 826 for hanging the surface roll. As the third chain 802 drives, it drives the surface roll to move. The cross-sectional shape of the surface roll lifting hanging plate 803 is J-shaped. A number of first clearance grooves 812 evenly distributed and in one-to-one cooperation with the transition claws 808 are axially formed in the surface roll lifting hanging plate 803 along the third sprocket 801;

[0034] The correction mechanism includes a lead screw 822 rotatably arranged between the two third sprockets 801. A lead screw nut 823 is arranged on the lead screw 822. A driving push plate 824 is fixedly arranged on the lead screw nut 823. Driven push plates 821 distributed on both sides of the driving push plate 824 are arranged on the surface roll lifting hanging plate 803. A shifting motor 804 is arranged on the forming and correcting frame. The output shaft end of the shifting motor 804 is connected to one end of the lead screw 822 through a gear transmission mechanism 820; Through the above specific structural design, the shifting motor 804 drives the lead screw 822 to rotate through the gear transmission mechanism 820. The lead screw nut 823 moves on the lead screw 822, driving the driving push plate 824 to move. The driven push plates 821 on both sides of the driving push plate 824 are arranged on the surface roll lifting hanging plate 803. When the driving push plate 824 moves, it will push the driven push plates 821, so that the surface roll lifting hanging plate 803 moves axially along the third sprocket 801, realizing the correction of the position of the surface roll and ensuring the accurate position of the surface roll on the third chain drive mechanism.

[0035] A fourth motor 807 for driving the transition roller 806 to rotate is arranged on the forming and correcting frame. The shifting claw assembly includes a claw 819 hinged on the forming and correcting frame, which can play a role of blocking and guiding when the surface roll passes through, and cooperate with the shifting claw 817 and others to realize the folding and bending operation of the surface roll. A second cylinder 818 for driving the claw 819 to be hingedly rotated is arranged on the forming and correcting frame;

[0036] On both sides of the retaining claw 819, there are two turntables 816 symmetrically distributed with it as the center. The two turntables 816 are arranged in an inclined V shape. On each turntable 816, there are two pawls 817 symmetrically distributed with its rotation axis as the center. The outer contour of the pawl 817 is in the shape of a J. On the back sides of the two turntables 816 facing away from each other, there are linear adjustment structures 809 for adjusting the distance between the two. The push rod head of the linear adjustment structure 809 is rotatably connected to the turntable 816 through a rotary joint 814. On the forming and correcting frame, there is a fifth motor 825 for driving the turntable 816 to rotate. The output shaft end of the fifth motor 825 is connected to the turntable 816 through a toothed belt drive structure, and a universal joint 815 is connected between the turntable 816 and the driven shaft end of the toothed belt drive structure; the fifth motor 825 drives the turntable 816 to rotate through the toothed belt drive structure. When the turntable 816 rotates, while applying a force to the facing roll, the pawls 817 will also approach each other, and cooperate with the retaining claw 819 to achieve the folding and bending of the facing roll. The linear adjustment structure 809 is used to adjust the distance between the two turntables 816 to meet the processing requirements of facing rolls of different sizes. The rotary joint 814 and the universal joint 815 ensure the flexibility and stability during the transmission process.

[0037] On both sides of the retaining claw 819, there are two arc-shaped guiding plates 810 symmetrically distributed with it as the center. The arc-shaped guiding plates 810 are fixedly arranged on the forming and correcting frame. The arc-shaped guiding plates 810 play a guiding role during the folding and bending of the facing roll, enabling the facing roll to move along a predetermined trajectory and ensuring the effect of folding and bending.

[0038] Working principle:

[0039] During use, the sixth motor 811 of the forming and correcting machine 8 drives the roller 813 to rotate. The transition claw 808 on the roller 813 supplies materials to the third chain drive mechanism composed of two third sprockets 801 and a third chain 802. The vision camera 805 detects the facing roll. The shifting motor 804 of the third chain drive mechanism drives the lead screw 822 to rotate through the gear drive mechanism 820. The lead screw nut 823 drives the active push plate 824 to move, and the driven push plate 821 moves accordingly to correct the position of the facing roll. The fourth motor 807 drives the transition roller 806 to rotate. The second cylinder 818 drives the retaining claw 819 to rotate. The fifth motor 825 drives the component composed of the turntable 816 and the pawl 817 to rotate through the toothed belt drive structure, and performs a W-shaped folding and bending on the facing roll passing through the transition roller 806. The arc-shaped guiding plate 810 assists the movement of the facing roll.

[0040] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
