Abstract
Description
Technical Field
[0001] This utility model relates to the field of bread processing technology, specifically to a visual correction device for dough rolls. Background Technology
[0002] In the processing of rolled dough, operations such as feeding, position correction, inspection, and folding / bending are required to ensure that the dough achieves the desired shape and positional accuracy. Roll processing has strict requirements for positional accuracy. Visual inspection can accurately capture the actual position of the dough and, after comparison with a standard position, adjust it through a correction mechanism to ensure that the dough is in the accurate position in subsequent processing stages. This avoids shape and size discrepancies due to positional deviations, reducing the generation of defective and scrap products. For example, if the initial position is inaccurate when folding and bending the dough, the shape will be distorted after folding, affecting product quality. Current technology cannot achieve precise correction of the rolled dough. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] See Figures 1-7 As shown, this utility model provides a visual correction device for dough rolls. The main function of the forming and correcting machine 8 is to perform a series of operations on the dough rolls, including feeding, position correction, detection, and folding and bending, to ensure that the dough rolls achieve the required shape and positional accuracy. The forming and correcting machine 8 includes a forming and correcting frame and an internal third chain drive mechanism for lifting the dough rolls from bottom to top. A dough roll feeding structure is provided on one side of the bottom of the third chain drive mechanism for feeding it. A transition roller 806 is provided between the third chain drive mechanism and the straightening belt 9. The function of the transition roller 806 is to smoothly transition the dough rolls on the third chain drive mechanism to the straightening belt 9, ensuring the continuity of dough roll conveying. The third chain drive mechanism is equipped with a correction mechanism for correcting the position of the roll on it. The forming correction frame is equipped with a vision camera 805 for detecting the roll on the third chain drive mechanism. The camera is mounted on the forming correction frame and is used to detect the roll on the third chain drive mechanism. It can detect parameters such as the position and shape of the roll and provide feedback information for subsequent correction mechanism operations. Above the transition roller 806, there is a deflector claw assembly for realizing the folding and bending of the roll.
[0032] The dough roll feeding structure includes a rotating roller 813. One end of the rotating roller 813 is driven to rotate by a sixth motor 811 fixedly mounted on the forming and correcting frame. Several sets of transition claws 808 are evenly distributed around the central axis of the rotating roller 813 on its outer side. Each set includes several transition claws 808 evenly distributed along the axial direction of the rotating roller 813. When the rotating roller 813 rotates, the transition claws 808 grab the dough roll and convey it to the dough roll lifting plate 803 of the third chain drive mechanism, thus feeding the dough roll to the third chain drive mechanism. The first gap groove 812 on the dough roll lifting plate 803 engages with each transition claw 808, facilitating accurate placement of the dough roll onto the dough roll lifting plate 803 by the transition claws 808.
[0033] The third chain drive mechanism comprises two parallelly distributed third sprockets 801, which are meshed and connected by a third chain 802. A plurality of chain driven plates 826 are evenly distributed between the two third chains 802 along their transmission direction. Each chain driven plate 826 has a roll lifting hanger 803 that can be adjusted and moved axially along the third sprockets 801 under the drive of a correction mechanism. This hanger is used to mount the roll and, with the transmission of the third chain 802, drives the roll to move. The roll lifting hanger 803 has a J-shaped cross-section and a plurality of evenly distributed first clearance grooves 812 that mate with transition claws 808 along the axial direction of the third sprockets 801.
[0034] The correction mechanism includes a lead screw 822 rotatably mounted between two third sprockets 801, a lead screw nut 823 mounted on the lead screw 822, an active push plate 824 fixedly mounted on the lead screw nut 823, driven push plates 821 distributed on both sides of the active push plate 824 mounted on the roll lifting hanger 803, and a positioning motor 804 mounted on the forming correction frame. The output shaft of the positioning motor 804 is connected to one end of the lead screw 822 via a gear transmission mechanism 820. Through the above specific structural design, the positioning motor 804 drives the lead screw 822 to rotate via the gear transmission mechanism 820, and the lead screw nut 823 moves on the lead screw 822, thereby driving the active push plate 824 to move. The driven push plates 821 on both sides of the active push plate 824 are set on the roll lifting hanger 803. When the active push plate 824 moves, it will push the driven push plates 821, thereby causing the roll lifting hanger 803 to move along the axial direction of the third sprocket 801, realizing the correction of the roll position and ensuring the accurate position of the roll on the third chain drive mechanism.
[0035] The forming and correcting frame is equipped with a fourth motor 807 for driving the transition roller 806 to rotate. The deflector assembly includes a deflector 819 hinged to the forming and correcting frame, which can block and guide the roll as it passes by, and work with the deflector 817 to achieve the folding and bending operation of the roll. The forming and correcting frame is equipped with a second cylinder 818 for driving the deflector 819 to rotate hingedly.
[0036] Two turntables 816 are symmetrically distributed on both sides of the stop pawl 819, with the stop pawl 819 as the center. The two turntables 816 are arranged in an inclined V-shape. Each turntable 816 is provided with two pawls 817 symmetrically distributed with the rotation axis as the center. The pawls 817 have a J-shaped outline. On the opposite side of each turntable 816, there is a linear adjustment structure 809 for adjusting the distance between them. The push rod head of the linear adjustment structure 809 is rotatably connected to the turntable 816 through a rotary joint 814. A fifth motor 825 is installed on the forming and correcting frame to drive the turntable 816 to rotate. The output shaft of the fifth motor 825 is connected to the turntable 816 via a toothed belt drive structure, and the turntable 816 and the driven shaft of the toothed belt drive structure are connected by a universal joint 815. The fifth motor 825 drives the turntable 816 to rotate via the toothed belt drive structure. When the turntable 816 rotates, the pawls 817 apply force to the roll and move closer together, cooperating with the stop pawls 819 to achieve the folding and bending of the roll. A linear adjustment structure 809 is used to adjust the distance between the two turntables 816 to adapt to the processing requirements of rolls of different sizes. The rotary joint 814 and the universal joint 815 ensure flexibility and stability during the transmission process.
[0037] Two arc-shaped guide plates 810 are symmetrically distributed on both sides of the stop claw 819, with the arc-shaped guide plates 810 fixedly mounted on the forming and correction frame. The arc-shaped guide plates 810 play a guiding role during the folding and bending process of the roll, so that the roll moves along a predetermined trajectory and ensures the folding and bending effect.
[0038] Working principle:
[0039] In operation, the sixth motor 811 of the forming and straightening machine 8 drives the rotating roller 813 to rotate. The transition claw 808 on the rotating roller 813 feeds material to the third chain transmission mechanism, which consists of two third sprockets 801 and a third chain 802. The vision camera 805 detects the roll, and the shifting motor 804 of the third chain transmission mechanism drives the lead screw 822 to rotate through the gear transmission 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 roll. The fourth motor 807 drives the transition roller 806 to rotate, the second cylinder 818 drives the stop claw 819 to rotate, and the fifth motor 825 drives the component consisting of the turntable 816 and the shift claw 817 to rotate through the toothed belt transmission structure, performing a W-shaped folding bend on the roll that has passed through the transition roller 806. The arc-shaped guide plate 810 assists in the movement of the roll.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
