Description

Technical Field

[0001] This utility model relates to the field of steel plate cutting machine technology, and in particular to a feeding and conveying mechanism for a steel plate cutting machine. Background Technology

[0002] With the increasing automation in manufacturing, the application areas of steel plate cutting machines are constantly expanding. For example, the demand for steel plate cutting is increasing in industries such as automobiles, shipbuilding, construction, and steel. In order to improve production efficiency, reduce manual operation, and lower production costs, the feeding and conveying system of steel plate cutting machines has become particularly important.

[0003] Chinese patent CN213560639U discloses a feeding mechanism for a laser cutting machine. By rotating a knob, the mechanism sequentially drives the screw, the first gear, and the second gear to rotate, which in turn drives the first rack and the second rack to move the curved connecting rod and the C-shaped connecting rod. The first and second correction plates correct the material to prevent it from being cut without correction, which would lead to deviations in the work results and affect work efficiency.

[0004] However, the above technical solutions do not address the continuity of material conveying. That is, the steel plate loading method usually relies on manual labor or simple mechanical equipment to move the steel plates one by one to the cutting machine workbench, which results in low efficiency of steel plate loading and transmission. Therefore, the present invention solves the shortcomings of the above technical problems. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a feeding and conveying mechanism for a steel plate cutting machine.

[0006] This utility model proposes a feeding and conveying mechanism for a steel plate cutting machine, including a stacking frame for stacking steel plates. A support platform is fixedly connected to the lower surface of the stacking frame via a support plate. Support frames are symmetrically distributed and fixedly connected to the upper surface of the support platform. A conveying plate is fixedly connected to one side surface of the two support frames. A conveying mechanism is provided on the upper surface of the support platform. The conveying mechanism includes a pushing block. When the pushing block reciprocates horizontally on the lower surface of the stacking frame, it pushes the bottommost steel plate forward for conveying.

[0007] Preferably, the conveying mechanism further includes a linkage block fixedly connected to the lower surface of the push block, and a guide groove is provided inside the lower end of the palletizing frame, with the outer surface of the linkage block slidably connected to the inner surface of the guide groove.

[0008] With the above technical solution, the material dropping end of the conveyor plate extends to the material feeding end of the steel plate cutting machine. In order to transfer the stacked steel plates to the steel plate cutting machine for processing in sequence, the linkage block moves horizontally inside the guide slide, thereby causing the push block to push the bottom layer of steel plates forward and slide them from the conveyor plate to the steel plate cutting machine.

[0009] Preferably, the conveying mechanism further includes a mounting block fixedly connected to the upper surface of the support platform, a swing rod hinged to one side surface of the mounting block, a swing opening fixedly communicating with the lower surface of the guide groove on the lower surface of the stacking frame, the outer surface of the swing rod slidably connected to the inner wall of the swing opening, a movable groove on the lower surface of the linkage block, and the inner wall of the upper movable hole of the swing rod hinged to the inner wall of the movable groove through a connecting shaft.

[0010] In order to control the linkage block to drive the push block to move horizontally on the lower surface of the stacking frame, the swing rod is reciprocated in a fan shape between the swing openings, thereby driving the linkage block to move back and forth. This allows the push block to continuously push the stacked steel plates. In order to achieve continuous swing of the swing rod, the range of motion of the swing rod is increased by setting the movable groove and movable hole, so that its reciprocating motion is unrestricted.

[0011] Preferably, the conveying mechanism further includes a movable wheel rotatably connected to one side surface of the swing arm, crossbeam plates are symmetrically distributed and fixedly connected to the upper surface of the support platform, a drive shaft is rotatably connected to the surface of the crossbeam plates through a bearing, a cam is fixedly sleeved on the outer surface of the drive shaft, and the convex arc surface of the cam is slidably connected to the outer surface of the movable wheel.

[0012] With the above technical solution, in order to drive the swing arm to perform a reciprocating fan-shaped swinging action, the drive shaft on the crossbeam plate rotates, which drives the cam to rotate circumferentially. When the convex arc surface of the cam contacts the movable wheel, it will squeeze the swing arm to the left side of the swing opening. At this time, the push block is on one side of the bottom steel plate, so the swing arm cannot push the material. When the cam disengages from the movable wheel, that is, the cam can no longer squeeze the swing arm, causing the swing arm to swing to the right side of the swing opening. At this time, the linkage block drives the push block to move horizontally, thereby pushing and transmitting the bottom steel plate.

[0013] Preferably, the conveying mechanism further includes a connecting block fixedly connected to the lower surface of the palletizing frame, a return spring fixedly connected to one side surface of the connecting block, and the free end of the return spring fixedly connected to one side surface of the swing rod.

[0014] In order to control the swing arm to swing to the right side of the swing opening after the cam disengages from the movable wheel, the above technical solution is used to stretch the return spring when the cam contacts the movable wheel. After disengaging from the contact, the return spring resets, causing the swing arm to complete the swinging action.

[0015] Preferably, the conveying mechanism further includes a fixed block fixedly connected to the inner surface of the support frame and a sliding block slidably connected to the inner surface of the support frame. The inner surfaces of the sliding block and the fixed block are respectively rotatably connected to a transmission roller via a bearing. The upper surface of the fixed block and the inner top surface of the support frame are respectively fixedly connected to a buffer telescopic rod with a buffer spring. The telescopic ends of the buffer telescopic rod are respectively fixedly connected to the upper and lower surfaces of the sliding block.

[0016] Through the above technical solution, the steel plate is pushed forward and backward. In order to achieve the continuity of its transmission, the rotation of the transmission rollers is used to continue to transport the steel plate forward, so that the steel plate falls from the transmission plate to the steel plate cutting machine for processing. In order to realize the transmission function of the transmission rollers, the height of the upper transmission rollers can be adjusted under the action of the buffer telescopic rod. That is, after the steel plate is pushed forward, the upper transmission rollers are pushed upward. At this time, the upper and lower surfaces of the steel plate are in contact with the surfaces of the two transmission rollers respectively. Thus, when the lower transmission rollers rotate, the upper transmission rollers can be rotated through the squeezing action, thereby squeezing and transporting the steel plate.

[0017] Preferably, the conveying mechanism further includes a synchronous belt assembly installed on the outer surface of the drive shaft and the lower transmission roller, and a geared motor is fixedly connected to the upper surface of the support platform. The outer surface of the output shaft of the geared motor is fixedly connected to the outer surface of the lower transmission roller through a coupling.

[0018] In order to achieve the linkage between the push block and the transmission roller and enable it to continuously transport the steel plate, the synchronous belt assembly includes synchronous pulleys installed on the outer surface of the lower transmission roller shaft and the outer surface of the drive shaft, as well as a synchronous belt that drives the two synchronous pulleys. Thus, when the reduction motor controls the rotation of the lower transmission roller, the drive shaft can be rotated under the transmission of the synchronous belt assembly, thereby realizing the rotation of the cam.

[0019] The beneficial effects of this utility model are as follows:

[0020] By setting up a conveying mechanism, the material can be continuously conveyed to neatly stacked steel plates. During the adjustment process, after the cam disengages from the movable wheel, it can no longer squeeze the swing rod, causing the swing rod to swing to the right side of the swing opening. At this time, the linkage block drives the push block to move horizontally, thus pushing and conveying the bottom layer of steel plates. After the steel plates are pushed forward, they push the upper conveyor rollers upward. At this time, the upper and lower surfaces of the steel plates are in contact with the surfaces of the two conveyor rollers respectively. When the lower conveyor rollers rotate, the upper conveyor rollers can be rotated through the squeezing action, thereby squeezing and conveying the steel plates. Therefore, the reciprocating swing of the swing rod and the rotation of the conveyor rollers can realize the continuous conveying of steel plates, thereby improving work efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-4A feeding and conveying mechanism for a steel plate cutting machine includes a stacking frame 1 for stacking steel plates. A support platform 2 is fixedly connected to the lower surface of the stacking frame 1 via a support plate. Support frames 3 are fixedly connected to the upper surface of the support platform 2 in a symmetrical manner. A conveying plate 4 is fixedly connected to one side surface of the two support frames 3. A conveying mechanism is provided on the upper surface of the support platform 2. The conveying mechanism includes a pushing block 5. When the pushing block 5 moves horizontally back and forth on the lower surface of the stacking frame 1, it pushes the bottommost steel plate forward for conveying.

[0028] The material dropping end of the conveyor plate 4 extends to the material feeding end of the steel plate cutting machine. In order to transfer the stacked steel plates to the steel plate cutting machine for processing in sequence, the conveying mechanism also includes a linkage block 6 fixedly connected to the lower surface of the push block 5. The lower end of the stacking frame 1 is provided with a guide groove 7. The guide groove 7 moves horizontally, thereby causing the push block 5 to push the bottom layer of steel plate forward and slide it from the conveyor plate 4 to the steel plate cutting machine.

[0029] To control the linkage block 6 to drive the push block 5 to move horizontally on the lower surface of the stacking frame 1, the conveying mechanism also includes a mounting block 8 fixedly connected to the upper surface of the support platform 2. A swing rod 9 is hinged to one side surface of the mounting block 8. A swing opening 10 is opened on the lower surface of the stacking frame 1 and is fixedly connected to the lower surface of the guide slide 7. The outer surface of the swing rod 9 is slidably connected to the inner wall of the swing opening 10. The swing rod 9 swings back and forth in a fan shape between the swing openings 10, thereby driving the linkage block 6 to move back and forth, so that the push block 5 can continuously push the stacked steel plates. In order to realize the continuous swing of the swing rod 9, a movable groove 11 is opened on the lower surface of the linkage block 6. The inner wall of the upper movable hole of the swing rod 9 is hinged to the inner wall of the movable groove 11 through a connecting shaft. The movable groove 11 and the movable hole increase the range of motion of the swing rod 9, so that its reciprocating motion is unrestricted.

[0030] To drive the swing arm 9 to perform a reciprocating fan-shaped swing motion, the conveying mechanism also includes a movable wheel 12 rotatably connected to one side surface of the swing arm 9. A crossbeam plate 13 is symmetrically distributed and fixedly connected to the upper surface of the support platform 2. A drive shaft 14 is rotatably connected to the surface of the crossbeam plate 13 through a bearing. A cam 15 is fixedly sleeved on the outer surface of the drive shaft 14. The convex arc surface of the cam 15 is slidably connected to the outer surface of the movable wheel 12. The rotation of the drive shaft 14 on the crossbeam plate 13 drives the cam 15 to rotate circumferentially. When the convex arc surface of the cam 15 contacts the movable wheel 12, it will squeeze the swing arm 9 to the left side of the swing opening 10. At this time, the push block 5 is on one side of the bottom steel plate, and the swing arm 9 cannot push the material. When the cam 15 disengages from the movable wheel 12, that is, the cam 15 can no longer squeeze the swing arm 9, causing the swing arm 9 to swing to the right side of the swing opening 10. At this time, the linkage block 6 drives the push block 5 to move horizontally, thereby pushing and conveying the bottom steel plate.

[0031] In order to control the swing arm 9 to swing to the right side of the swing opening 10 after the cam 15 disengages from the movable wheel 12, the conveying mechanism also includes a connecting block 16 fixedly connected to the lower surface of the stacking frame 1. A return spring 17 is fixedly connected to one side surface of the connecting block 16. The free end of the return spring 17 is fixedly connected to one side surface of the swing arm 9. When the cam 15 contacts the movable wheel 12, it stretches the return spring 17. After disengaging from the contact, the return spring 17 resets, causing it to drive the swing arm 9 to complete the swinging action.

[0032] The steel plate is pushed forward and backward. To ensure continuous transmission, the conveying mechanism also includes a fixed block 18 fixedly connected to the inner surface of the support frame 3 and a sliding block 19 slidably connected to the inner surface of the support frame 3. The inner surfaces of the sliding block 19 and the fixed block 18 are respectively rotatably connected to a transmission roller 20 via bearings. The upper surface of the fixed block 18 and the inner top surface of the support frame 3 are respectively fixedly connected to a buffer telescopic rod 21 with a buffer spring. The telescopic ends of the buffer telescopic rod 21 are respectively fixedly connected to the upper and lower surfaces of the sliding block 19. The transmission roller 20 rotates... This allows the steel plate to continue being conveyed forward, falling from the conveyor plate 4 onto the steel plate cutting machine for processing. To achieve the conveying function of the conveyor roller 20, the upper conveyor roller 20 can be height-adjusted under the action of the buffer telescopic rod 21. That is, after the steel plate is pushed forward, the upper conveyor roller 20 is pushed upward. At this time, the upper and lower surfaces of the steel plate are in contact with the surfaces of the two conveyor rollers 20 respectively. Thus, when the lower conveyor roller 20 rotates, the upper conveyor roller 20 can be rotated through the squeezing action, thereby squeezing and conveying the steel plate.

[0033] To achieve linkage between the push block 5 and the transmission roller 20, enabling continuous conveying of the steel plate, the conveying mechanism also includes a synchronous belt assembly 22 installed on the outer surface of the drive shaft 14 and the lower transmission roller 20. A geared motor 23 is fixedly connected to the upper surface of the support platform 2. The outer surface of the output shaft of the geared motor 23 is fixedly connected to the outer surface of the lower transmission roller 20 through a coupling. The synchronous belt assembly 22 includes synchronous pulleys installed on the outer surface of the lower transmission roller 20 and the outer surface of the drive shaft 14, as well as a synchronous belt that drives the two synchronous pulleys. Thus, when the geared motor 23 controls the rotation of the lower transmission roller 20, the drive shaft 14 can be rotated under the transmission of the synchronous belt assembly 22, thereby realizing the rotation of the cam 15.

[0034] By setting up a conveying mechanism, the material can be continuously conveyed to neatly stacked steel plates. During the adjustment process, after the cam 15 disengages from the movable wheel 12, that is, the cam 15 can no longer squeeze the swing rod 9, causing the swing rod 9 to swing to the right side of the swing opening 10. At this time, the linkage block 6 drives the push block 5 to move horizontally, thereby pushing and conveying the bottom layer of steel plates. After the steel plate is pushed forward, it pushes the upper layer of conveying roller 20 upward. At this time, the upper and lower surfaces of the steel plate are in contact with the surfaces of the two conveying rollers 20 respectively. Thus, when the lower layer of conveying roller 20 rotates, the upper layer of conveying roller 20 can be rotated through the squeezing action, thereby squeezing and conveying the steel plate. Therefore, the reciprocating swing of the swing rod 9 and the rotation of the conveying roller 20 can realize the continuous conveying of steel plates, thereby improving work efficiency.

[0035] Working principle: In a specific embodiment of this utility model, steel plates are positioned and stacked in the stacking frame 1. When the steel plates are continuously fed, the reduction motor 23 works to control the rotation of the lower transmission roller 20. Under the transmission of the synchronous belt assembly 22, the rotation of the drive shaft 14 can be realized.

[0036] The drive shaft 14 on the crossbeam plate 13 rotates, causing the cam 15 to rotate circumferentially. When the convex arc surface of the cam 15 contacts the movable wheel 12, it will squeeze the swing rod 9 to the left side of the swing opening 10. At this time, the push block 5 is on the side of the bottom steel plate, so the swing rod 9 cannot push the material. When the cam 15 disengages from the movable wheel 12, that is, the cam 15 can no longer squeeze the swing rod 9, the reset spring 17 resets, causing it to drive the swing rod 9 to swing to the right side of the swing opening 10. At this time, the linkage block 6 drives the push block 5 to move horizontally in the guide groove 7, so that the bottom steel plate can be pushed and transmitted.

[0037] After the steel plate is pushed forward, it pushes the upper conveyor roller 20 upward. At this time, the upper and lower surfaces of the steel plate are in contact with the surfaces of the two conveyor rollers 20 respectively. Thus, when the lower conveyor roller 20 rotates, the upper conveyor roller 20 can be rotated through the squeezing action, thereby squeezing and conveying the steel plate.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
