Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thread-touching mechanisms, in particular to a thread-touching mechanism for an automatic box-stitching machine. Background Art
[0002] The crease-contacting mechanism of the carton stitching machine is a key part of the carton stitching machine. It is mainly responsible for performing precise creasing operations on the cardboard when it is conveyed to a specific area. The crease-contacting mechanism presses clear creases on the cardboard through its pressing plates or pressing wheels and other components, providing an accurate positioning reference for subsequent folding and forming.
[0003] The current automatic carton stitching machine's touch-line mechanism performs poorly in the cardboard creasing operation and has obvious defects. The mechanism fails to effectively pre-position the cardboard before creasing, which causes the cardboard to easily deviate during the creasing process. This deviation not only affects the accuracy and consistency of the creasing, but is also likely to cause defects or structural instability after the carton is formed. Due to the negligence of the touch-line mechanism in positioning the cardboard, it may also cause paper jams, shutdowns and other faults on the production line, seriously affecting production efficiency. Therefore, we propose a touch-line mechanism for an automatic carton stitching machine. Utility Model Content
[0004] The utility model aims to provide a line-touching mechanism for an automatic carton nailing machine to solve the problem in the above-mentioned background technology that the mechanism fails to effectively pre-position the cardboard before creasing, which causes the cardboard to easily deviate during the creasing process. This deviation not only affects the accuracy and consistency of the creasing, but is also likely to cause defects or structural instability after the carton is formed. Due to the negligence of the line-touching mechanism in positioning the cardboard, it may also cause paper jams, shutdowns and other faults on the production line, seriously affecting the production efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic box nailing machine line contact mechanism, including a conveyor belt, wherein the number of the conveyor belts is two, a support seat is fixedly installed between the two conveyor belts, a wire pressing groove is opened at the center of the top of the support seat, a first spring is fixedly connected to the bottom of the wire pressing groove, an ejection block is fixedly connected to the upper end of the first spring, the front and rear surfaces of the two conveyor belts are fixedly connected to a fixing frame, a lifting plate is arranged at a top position of the fixing frame, a cylinder is fixedly installed at the center of the top of the fixing frame, a connecting plate is arranged at the lower end of the lifting plate, and the connecting plate is fixedly connected to the bottom of the wire pressing groove. The front end and the rear end of both sides of the bottom of the connecting plate are fixedly installed with pressure rods, and positioning plates are provided on both sides of the lower end of the connecting plate, and a groove is opened in the center of the top of the positioning plate, and a wire pressing plate is fixedly installed at the center of the bottom of the lifting plate, and mounting tubes are fixedly installed at the two sides of the top of the lifting plate, and the top of the mounting tube is fixedly connected with a second spring, and the lower end of the second spring is fixedly connected with a movable block, and a ball is rollingly installed on the outer wall of the movable block, and a vertical rod is fixedly connected to the center of the bottom of the movable block, and the lower end of the vertical rod passes through the outside of the mounting tube and the lifting plate in sequence and is fixedly connected to the upper end of the connecting plate.
[0006] Compared with the prior art, the beneficial effects of the utility model are:
[0007] The line-touching mechanism of the automatic box nailing machine is designed with a connecting plate, a pressure rod, a positioning plate, a mounting tube, a second spring, a movable block, a ball and a vertical rod. When the cylinder drives the lifting plate to make the line-pressing plate indent the cardboard entering the line-touching area, since the heights of the positioning plates on both sides are lower than the line-pressing plate, the two positioning plates will contact the cardboard in advance to press the cardboard. Due to the existence of the second spring, the line-pressing plate is not restricted by the positioning plate and continues to move downward and indent the cardboard, so that the line-touching mechanism has the function of positioning the cardboard, ensuring the stability of the cardboard during the positioning process, thereby effectively avoiding the deviation of the cardboard before indentation, and improving the accuracy and consistency of the indentation. The design of the first spring and the ejection block plays a key role in preventing paper jams. During the cardboard indentation process, even if the cardboard is under pressure and tends to move downward, the elastic force of the first spring can timely push the ejection block upward to avoid the cardboard from being stuck in the line-pressing groove. This design effectively prevents transmission interruption or equipment damage caused by cardboard being stuck, and ensures the continuity and stability of the production line.

[0017] The cylinder 7 is fixedly connected with a piston rod through the output end at the bottom thereof, and the lower end of the piston rod is fixedly connected with the center of the top of the lifting plate 6. The lifting plate 6 is driven by the cylinder 7 to make the creasing plate 11 perform a creasing operation on the cardboard.
[0018] The lower ends of the four pressing rods 9 arranged on both sides are fixedly connected to the upper ends of the two positioning plates 10 respectively, and a buffer cushion is fixedly installed on the bottom of the positioning plate 10 to prevent the cardboard from being worn when positioning the cardboard.
[0019] The groove 19 is a rectangular structure, and the lower end of the wire pressing plate 11 passes through the outside of the groove 19. Due to the existence of the second spring 13 and the groove 19, the connection plate 8 will not be hindered from moving up and down.
[0020] The movable block 14 is a cylindrical structure, and a plurality of balls 15 are provided. The surfaces of the plurality of balls 15 are in contact with the inner wall of the mounting tube 12 , thereby ensuring the sliding property of the movable block 14 in the mounting tube 12 .
[0021] A feed port and a discharge port are respectively provided on both sides of the outer wall of the fixed frame 5 corresponding to the upper ends of the two conveyor belts 1. Cardboard is provided on the upper ends of the two conveyor belts 1. Both ends of the cardboard extend to the outside of the feed port and the discharge port respectively.

[0023] Working principle: The cardboard is transported through two conveyor belts 1. When the cardboard is transported to the top of the support seat 2 through the feed port, the cylinder 7 drives the lifting plate 6 to descend. At this time, the lifting plate 6 drives the two installation cylinders 12 at the top and the pressing plate 11 at the bottom to move downward. Since the position of the positioning plate 10 is lower than the pressing plate 11, the installation cylinder 12 drives the positioning plate 10 to contact the two sides of the cardboard in advance. Then, the cylinder 7 continues to drive the lifting plate 6 to descend, and the pressing plate 11 performs a creasing operation on the cardboard. At this time, the positioning plate 10 uses the vertical rod 16 to make the movable The moving block 14 slides upward in the mounting tube 12 and compresses the second spring 13. The pressing plate 11 moves downward to indent the cardboard. Through the characteristics of the second spring 13, the positioning plate 10 firmly fixes the cardboard to ensure that the cardboard will not move during the indentation process. At the same time, if the indentation of the cardboard is stuck in the pressing groove 3, the first spring 4 in the pressing groove 3 will push the ejection block 20 upward to prevent the cardboard from getting stuck. After the indentation is completed, the cylinder 7 drives the lifting plate 6 to rise, and the cardboard continues to be conveyed to the discharge port along the conveyor belt 1, completing the entire contact process.
[0024] In summary: the automatic box nailing machine line-touching mechanism, through the design of the connecting plate 8, the pressure rod 9, the positioning plate 10, the mounting tube 12, the second spring 13, the movable block 14, the ball 15 and the vertical rod 16, the cylinder 7 drives the lifting plate 6 to make the line-pressing plate 11 indent the cardboard entering the line-touching area. Since the height of the positioning plates 10 on both sides is lower than the line-pressing plate 11, the two positioning plates 10 will contact the cardboard in advance to press the cardboard. Due to the existence of the second spring 13, the line-pressing plate 11 is not restricted by the positioning plate 10 and continues to move downward and indent the cardboard, so that the line-touching mechanism It has the function of positioning the cardboard, ensuring the stability of the cardboard during the positioning process, thereby effectively avoiding the deviation of the cardboard before indentation, and improving the accuracy and consistency of the indentation. The design of the first spring 4 and the ejection block 20 plays a key role in preventing paper jams. During the cardboard indentation process, even if the cardboard is under pressure and tends to move downward, the elastic force of the first spring 4 can push the ejection block 20 upward in time to avoid the cardboard from being stuck in the crimping groove 3. This design effectively prevents transmission interruption or equipment damage caused by cardboard being stuck, and ensures the continuity and stability of the production line.
