Description

Technical Field

[0001] The utility model belongs to the technical field of leveling machines and relates to a feeding head of a leveling machine. Background Art

[0002] The leveler is a machine that flattens uneven metal sheets by squeezing them into a certain thickness through upper and lower rollers. The feeder head of the leveler usually uses upper and lower transfer rollers to transport the coiled material.

[0003] The transmission method used by the upper and lower leveling wheels of commonly used leveling feeders is mostly the mutual meshing transmission of gear sets. Due to the large number of upper and lower leveling wheels, many gears need to be meshed with each other. During the transmission process of numerous gear meshing, some metal debris and other debris will be generated. As the use time increases, the metal debris and debris inside will increase, which will affect the leveling effect.

[0004] Chinese patent CN207386384U discloses a liftable leveler feeder. The leveler feeder consists of a base and an upper head, secured to the upper side panels. A pneumatic cylinder controls the lifting and closing of the upper head. The upper head is secured to the left and right upper side panels, and the cylinder allows it to be easily lifted, making it easier for workers to clean out metal debris and debris, improving work efficiency.

[0005] The leveling feeder uses a cylinder to control the lifting and closing of the upper head of the leveling feeder. After lifting, one end of the upper head of the leveling feeder rotates upward, and the other end is still located at the lower side plate, which makes the gap at the hinge of the lower side plate smaller, which is not conducive to cleaning by the staff.

[0006] A leveling machine that is easy to clean is disclosed in Chinese patent CN212857190U. The leveling machine has an internally arranged snap-fit cleaning module that contacts the roller. The driving device drives the roller to rotate and generates friction with the cleaning module to clean the dust on the roller. At the same time, the nozzle arranged inside can flush the roller to enhance the cleaning effect.

[0007] After the leveling machine completes the cleaning of the rollers through the engaging cleaning module, metal debris will accumulate on the engaging cleaning module. It is still necessary to disassemble the multiple cleaning modules separately for cleaning and then reinstall them.

[0053] A first motor 15 is fixedly connected to one side of the lower side plate 6 , and the first motor 15 drives a lower conveying roller 13 located at the end to rotate.

[0054] The same end of the plurality of lower conveying rollers 13 rotates and penetrates the lower side plate 6 , and the ends of the plurality of lower conveying rollers 13 extending outward from the lower side plate 6 are fixedly sleeved with the first gear 11 .

[0055] Several lower transmission gears 12 are arranged at intervals on one side of the lower side plate 6. The rotation axes of the several lower transmission gears 12 are on the same horizontal plane. The lower transmission gears 12 are respectively located between the two first gears 11 and are meshed with the first gears 11 on both sides.

[0056] Driving mechanisms are provided on both sides of the box body 1 , and the driving mechanisms drive the top plate 8 to move vertically up and down above the box body 1 .

[0057] The driving mechanism includes a hydraulic telescopic rod 3 . The top ends of the corresponding two sides of the box body 1 are fixedly connected with lower fixed plates 2 , and the top of each lower fixed plate 2 is fixedly connected with a hydraulic telescopic rod 3 .

[0058] Upper fixed plates 9 are fixedly connected to both sides of the top plate 8 , and the output ends of the hydraulic telescopic rods 3 are fixedly connected to the bottom ends of the corresponding upper fixed plates 9 .

[0059] The box body 1 and the top plate 8 are connected via a connecting mechanism.

[0060] The connecting mechanism includes a lower connecting plate 4 and an upper connecting plate 7. Both ends of the lower side plate 6 are fixedly connected to the lower connecting plate 4.

[0061] The bottom end of the upper connecting plate 7 is fixedly connected with a screw 5, and a chute is provided on the lower connecting plate 4, and the screw 5 passes through the corresponding chute.

[0062] Both ends between the two lower side plates 6 are rotatably connected to lower rotating rollers 24 , and the plurality of lower conveying rollers 13 are located between the two lower rotating rollers 24 .

[0063] Both ends between the two upper side plates 21 are rotatably connected with upper rotating rollers 10, and several upper conveying rollers 14 are located between the two upper rotating rollers 10. The lower rotating rollers 24 and the upper rotating rollers 10 located at the same end correspond to each other up and down.

[0064] Working principle:

[0065] When in use, the hydraulic telescopic rod 3 is started to move the upper fixed plate 9 up and down, and the top plate 8 and the upper side plate 21 are moved up and down, driving the upper rotating roller 10 and the upper conveying roller 14 to move up and down, changing the distance between the upper rotating roller 10 and the lower rotating roller 24, so that the corresponding gap between the upper rotating roller 10 and the lower rotating roller 24 is adapted to the thickness of the coil to be conveyed.

[0066] When the upper side plate 21 moves, it drives the upper connecting plate 7 to slide on one side of the lower connecting plate 4, causing the screw 5 to slide in the corresponding slot. After adjustment, the nut is rotated onto the screw 5 so that the nut abuts against one side of the lower connecting plate 4, fixing the upper connecting plate 7 and increasing stability.

[0067] When feeding, the first motor 15 and the second motor 16 are started respectively.

[0068] The first motor 15 drives a lower conveying roller 13 connected to it to rotate, so that the first gear 11 at the end of the lower conveying roller 13 rotates, and the lower transmission gear 12 meshing with it rotates. Through transmission, all the first gears 11 and the lower transmission gear 12 rotate, so that all the lower conveying rollers 13 rotate.

[0069] Similarly, the second motor 16 drives an upper conveying roller 14 connected thereto to rotate, causing a second gear 23 at the end of the upper conveying roller 14 to rotate. Through transmission, all the second gears 23 and the upper transmission gear 22 rotate, causing all the upper conveying rollers 14 to rotate.

[0070] The coil first passes through a set of upper rotating rollers 10 and lower rotating rollers 24, which correspond to each other vertically. Then, it is transported by upper conveying rollers 14 and lower conveying rollers 13, and finally discharged by another set of upper rotating rollers 10 and lower rotating rollers 24, which correspond to each other vertically. The purpose of flattening the coil is achieved by the two sets of upper rotating rollers 10 and lower rotating rollers 24.

[0071] After long-term use, it is necessary to clean the upper conveying mechanism and the lower conveying mechanism. First, the nut on the screw 5 is turned out.

[0072] Start the hydraulic telescopic rod 3 to push the upper fixed plate 9 upward, move the entire upper conveying mechanism upward, increase the gap between the upper conveying mechanism and the lower conveying mechanism, and make it easier for staff to clean the upper conveying mechanism and the lower conveying mechanism respectively.

[0073] After cleaning is completed, the upper conveying mechanism is moved downward to a suitable position by the hydraulic telescopic rod 3 and then fixed with nuts. Example 2

[0074] like Figure 5-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that:

[0075] The drive mechanism includes a third motor 18. The lower fixed plate 2 is fixedly connected to the corresponding sides of the housing 1. The top of the lower fixed plate 2 is fixedly connected to the fixed frame 17. The third motor 18 is fixedly connected to one side of the top of the fixed frame 17. The output shaft of the third motor 18 rotates and passes through the fixed frame 17. The end of the output shaft of the third motor 18 is fixedly connected to a spiral drive block 19. The spiral drive block 19 and the fixed frame 17 are both tilted, so that the top of the spiral drive block 19 is constantly engaged with the rack 20. The spiral drive block 19 has a spiral line structure, and the rotation and engagement of the spiral drive block 19 drives the movement of the rack 20.

[0076] Both sides of the top plate 8 are fixedly connected to the upper fixed plate 9, and the bottom end of each upper fixed plate 9 is fixedly connected to a rack 20, which is engaged with the corresponding spiral drive block 19. The bottom end of the rack 20 slides through the corresponding lower fixed plate 2.

[0077] The connecting mechanism includes a lower connecting plate 4 and an upper connecting plate 7. Both ends of the lower side plate 6 are fixedly connected to the lower connecting plate 4, and both ends of the upper side plate 21 are fixedly connected to the upper connecting plate 7, which is slidably arranged on one side of the corresponding lower connecting plate 4.

[0078] A positioning groove is provided on one side of the lower connecting plate 4 close to the upper connecting plate 7 , and a positioning bar is fixedly connected to one side of the upper connecting plate 7 close to the lower connecting plate 4 , and the positioning bars are slidably arranged in the corresponding positioning grooves.

[0079] Working principle:

[0080] When adjusting the distance between the upper conveying mechanism and the lower conveying mechanism, the third motor 18 is started to drive the spiral drive block 19 to rotate forward. The top end of the rotating spiral drive block 19 will engage with the rack 20, and the spiral drive block 19 outside the engagement will not contact the rack 20, thereby driving the rack 20 to move upward, driving the upper fixed plate 9 and the top plate 8 to move upward.

[0081] On the contrary, the third motor 18 is started to drive the spiral driving block 19 to rotate in the opposite direction, so that the spiral driving block 19 drives the rack 20 to move downward, and drives the upper fixing plate 9 and the top plate 8 to move downward.

[0082] Then, the top plate 8 drives the upper conveying mechanism to move up and down through the forward and reverse rotation of the third motor 18 .

[0083] When the top plate 8 drives the upper side plate 21 to move up and down, the upper connecting plate 7 moves up and down on one side of the lower connecting plate 4, causing the positioning bar to slide inside the positioning groove, so that the top plate 8 moves smoothly. Due to the cooperation between the spiral drive block 19 and the rack 20, the top plate 8 has a self-locking effect when moving, and does not need to be fixed with a nut, making adjustment more convenient.

[0084] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
