Description

Technical Field

[0001] This utility model relates to the field of sheet material processing and production, and in particular to a feeding platform with material positioning function. Background Technology

[0002] In the field of sheet material processing and production, the feeding table is a key piece of equipment that connects material storage with subsequent processing steps such as cutting, grinding, and assembly. Its operational stability and adaptability directly affect the overall production efficiency and processing quality.

[0003] However, existing feeding tables for sheet metal processing still have significant shortcomings: On the one hand, most feeding tables have fixed positioning structures, which can only adapt to sheet metal materials of a single width. When processing sheets of different widths, it is necessary to disassemble and replace the positioning components, which is cumbersome and time-consuming, seriously affecting the continuity of production. Even if some feeding tables have positioning adjustment functions, it is often necessary to readjust the entire feeding table to correct minor deviations in the material discharge position, further increasing the complexity of operation and time costs. On the other hand, the height of existing feeding tables is mostly fixed. When used with subsequent processing equipment with different entry heights, it is necessary to modify the height of the processing equipment or replace the feeding table with one of different height specifications. This not only increases the equipment investment cost but also significantly reduces the adaptability of the feeding table to different processing equipment, making it difficult to meet the needs of diverse processing scenarios.

[0004] Therefore, those skilled in the art have provided a feeding platform with material positioning function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a feeding table with material positioning function. With the provided adjustable positioning component, the front and rear distance of the positioning wheels can be flexibly adjusted to adapt to sheet materials of different widths and specifications. There is no need to replace the feeding table components, which greatly improves the compatibility with a variety of materials. Furthermore, deviation adjustment can be achieved by directly driving the positioning wheels to move laterally, without the need to readjust the entire feeding table, reducing operation time. With the provided height adjustment component, the hollow feeding table and the adjustable positioning component can be raised and lowered as a whole according to the entrance height of the subsequent processing equipment, without the need to modify the height of the processing equipment itself, which significantly improves the adaptability of the feeding table to different processing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A feeding platform with material positioning function includes a support base, and a hollow feeding platform is fixedly connected to the upper end of the support base through multiple positioning telescopic rods. An adjustable positioning component is provided on the hollow feeding platform, and a height adjustment component is provided between the support base and the hollow feeding platform.

[0008] The adjustable positioning assembly includes two bidirectional threaded rods and two movable seats. The two bidirectional threaded rods are rotatably connected between the front and rear inner walls of the hollow feeding platform. The two movable seats are slidably disposed inside the hollow feeding platform and threaded onto the two bidirectional threaded rods. Each movable seat has a calibration groove at its upper end. Calibration screws are rotatably connected to both sides of the front and rear inner walls of the two calibration grooves. Calibration sliders are slidably disposed inside each calibration groove and threaded onto corresponding calibration screws. Multiple positioning wheels are rotatably connected to the upper ends of each calibration slider. The hollow feeding platform has multiple adjustment grooves at its upper end and a drive groove inside. A first motor is fixedly disposed on one side of the hollow feeding platform. A drive box is fixedly connected to one end of one of the movable seats. A second motor is fixedly disposed on one side of the drive box. A controller is fixedly disposed at one end of the hollow feeding platform.

[0009] With the above technical solution, when the controller starts the first motor, the first motor drives the first worm gear in the drive slot to rotate. The two first worm wheels meshing with the first worm gear rotate synchronously, thereby driving the two bidirectional threaded rods to rotate synchronously between the front and rear inner walls of the hollow feeding table. This causes the two movable seats with threads on them to slide in opposite directions, realizing the adjustment of the front and rear distance of the positioning wheels to adapt to different widths of plates. When there is a slight deviation between the material discharge position and the inlet of the subsequent processing equipment, the controller starts the second motor. The second motor drives the second worm gear in the drive box to rotate. The two meshing second worm wheels drive the calibration screw to rotate, allowing the calibration slider with threads to slide along the calibration slot. This, in turn, drives the positioning wheel to move laterally to adjust the material discharge position. The whole system can not only adapt to materials of various widths without replacing parts, but also solves slight deviations through the lateral adjustment of the positioning wheels, reducing debugging time.

[0010] Furthermore, the height adjustment assembly includes two lifting threaded rods, both of which are rotatably connected to the support base. The outer walls of both lifting threaded rods are threaded with lifting sleeves, and both lifting sleeves are fixedly connected to the hollow feeding table. The support base has a transmission groove inside, and a third worm gear is rotatably connected between the inner walls of the two sides of the transmission groove. Two third worm wheels are rotatably connected between the upper and lower inner walls of the transmission groove. A third motor is fixedly installed on one side of the support base.

[0011] With the above technical solution, after the controller starts the third motor, the third motor will drive the third worm gear in the transmission groove of the support seat to rotate. The two third worm wheels meshing with the third worm gear will rotate synchronously, driving the two lifting threaded rods to rotate on the support seat. This will cause the threaded lifting sleeve to drive the hollow feeding table and the adjustable positioning component to rise and fall as a whole. Thus, the height of the feeding table can be flexibly adjusted according to the inlet height of the subsequent processing equipment without modifying the processing equipment, thereby improving adaptability.

[0012] Furthermore, two linkage shafts and linkage sleeves are rotatably connected to opposite ends of the two movable seats respectively. The two linkage shafts are slidably disposed in the corresponding linkage sleeves. One end of the two linkage shafts and linkage sleeves passes through the corresponding movable seat and is fixedly connected to the corresponding calibration screw. Two linkage blocks are fixedly connected to the outer walls of the two linkage shafts. Two linkage grooves are opened on the inner walls of the two linkage sleeves. Multiple linkage blocks are slidably disposed in the corresponding linkage grooves.

[0013] With the above technical solution, when the two moving seats slide along the bidirectional threaded rod to adjust the distance, the linkage shaft driven by one moving seat will slide axially in the linkage sleeve of the other moving seat, and the linkage block on the outer wall of the linkage shaft will always slide in the linkage groove on the inner wall of the linkage sleeve. This allows the linkage structure between the corresponding calibration screws to adapt to the distance adjustment of the moving seats. After the moving seats are adjusted, when the second worm gear controls the corresponding calibration screw to rotate, the other calibration screw can be rotated through the linkage structure.

[0014] Furthermore, a first worm is rotatably connected between the inner walls of both sides of the drive groove, and two first worm wheels are rotatably connected between the inner walls of the front and rear of the first worm. Both first worm wheels mesh with the first worm. One end of each of the two bidirectional threaded rods passes through the hollow feeding table and is fixedly connected to the corresponding first worm wheel. The output end of the first motor passes through the hollow feeding table and is fixedly connected to the first worm. The first motor and the controller are electrically connected.

[0015] With the above technical solution, the output end of the first motor passes through the hollow feeding table and is fixed to the first worm gear in the drive groove. After the first motor is started by the controller, the first worm gear drives the two meshing first worm wheels to rotate synchronously, thereby causing the two bidirectional threaded rods fixed to the first worm wheels to rotate synchronously.

[0016] Furthermore, a second worm gear is rotatably connected between the two inner walls of the drive box, and two second worm wheels are rotatably connected between the front and rear inner walls of the drive box. Both second worm wheels mesh with the second worm gear. One end of each of the two calibration screws near the drive box passes through the corresponding moving seat and the drive box and is fixedly connected to the corresponding second worm wheel. The output end of the second motor passes through the drive box and is fixedly connected to the second worm gear. The second motor and the controller are electrically connected.

[0017] With the above technical solution, the output end of the second motor passes through the drive box and is fixed to the second worm gear inside the box. After the second motor is started by the controller, the second worm gear drives the two meshing second worm wheels to rotate synchronously, causing the calibration screw fixed to the second worm wheels and close to the drive box to rotate.

[0018] Furthermore, both of the third worm gears mesh with the third worm, the lower ends of both of the lifting threaded rods pass through the support seat and are fixedly connected to the corresponding third worm gear, the output end of the third motor passes through the support seat and is fixedly connected to the third worm, and the third motor and the controller are electrically connected;

[0019] With the above technical solution, after the controller starts the third motor, the third worm can rotate, which in turn can rotate the two third worm wheels, thereby causing the corresponding lifting threaded rod to rotate.

[0020] Furthermore, each of the aforementioned positioning wheels is movably positioned within a corresponding adjustment groove;

[0021] With the above technical solution, when the moving seat is adjusted to the front and rear position or the calibration slider is adjusted to the lateral position, the positioning wheel connected to the two will move together. The positioning wheel always moves in the adjustment groove at the top of the hollow feeding table. The adjustment groove provides a stable movement path for the positioning wheel and avoids the positioning wheel being blocked by the feeding table body.

[0022] This utility model has the following beneficial effects:

[0023] 1. The present invention proposes a feeding table with material positioning function. Through the provided adjustable positioning component, it can flexibly adjust the front and rear distance of the positioning wheel by controlling the two moving seats to slide in opposite directions, so as to adapt to the sheet material of different width specifications. There is no need to replace the feeding table components, which greatly improves the compatibility with a variety of materials. Moreover, when there is a slight deviation between the material discharge position and the inlet of the subsequent processing equipment, the component can adjust the deviation by driving the positioning wheel to move laterally through the calibration screw and calibration slider, without the need to readjust the entire feeding table, thus reducing operation time.

[0024] 2. The present invention proposes a feeding platform with material positioning function. Through the provided height adjustment component, it can start the third motor through the controller according to the inlet height of the subsequent processing equipment, drive the third worm gear, the third worm wheel and the lifting threaded rod to work together, so that the lifting sleeve drives the hollow feeding platform and the adjustable positioning component to lift as a whole. There is no need to modify the height of the processing equipment itself, which significantly improves the adaptability of the feeding platform to different processing equipment.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-6This utility model provides a specific embodiment: a feeding platform with material positioning function, including a support base 1, a hollow feeding platform 3 fixedly connected to the upper end of the support base 1 by a plurality of positioning telescopic rods 2, an adjustable positioning component 4 provided on the hollow feeding platform 3, and a height adjustment component 5 provided between the support base 1 and the hollow feeding platform 3.

[0035] The adjustable positioning assembly 4 includes two bidirectional threaded rods 6 and two movable seats 7. The two bidirectional threaded rods 6 are rotatably connected between the front and rear inner walls of the hollow feeding table 3. The two movable seats 7 are slidably disposed inside the hollow feeding table 3 and threadedly fitted onto the two bidirectional threaded rods 6. Each movable seat 7 has a calibration groove 8 at its upper end. Calibration screws 9 are rotatably connected to both sides of the front and rear inner walls of the two calibration grooves 8. Calibration sliders 10 are slidably disposed inside each calibration groove 8 and threadedly fitted onto corresponding calibration screws 9. Multiple positioning wheels 11 are rotatably connected to the upper ends of each calibration slider 10. Multiple adjustment grooves 21 are provided at the upper end of the hollow feeding table 3, and the multiple positioning wheels 11 are positioned at the... The adjustment groove 21 is movable. When the moving seat 7 is adjusted forward and backward or the calibration slider 10 is adjusted laterally, the positioning wheel 11 connected to both will move accordingly. The positioning wheel 11 always moves within the adjustment groove 21 at the upper end of the hollow feeding table 3. The adjustment groove 21 provides a stable moving path for the positioning wheel 11, preventing the positioning wheel 11 from being blocked by the feeding table body. The hollow feeding table 3 has a drive groove 12 inside. A first motor 18 is fixedly installed on one side of the hollow feeding table 3. One end of one of the moving seats 7 is fixedly connected to a drive box 15. A second motor 19 is fixedly installed on one side of the drive box 15. A controller 20 is fixedly installed on one end of the hollow feeding table 3. A first worm gear 13 is rotatably connected between the inner walls of the two sides of the drive groove 12. Two first worm gears 14 are rotatably connected between the front and rear inner walls of the first worm 13. Both first worm gears 14 mesh with the first worm 13. One end of each of the two bidirectional threaded rods 6 passes through the hollow feeding table 3 and is fixedly connected to the corresponding first worm gear 14. The output end of the first motor 18 passes through the hollow feeding table 3 and is fixedly connected to the first worm 13. The first motor 18 is electrically connected to the controller 20. The output end of the first motor 18 passes through the hollow feeding table 3 and is fixed to the first worm 13 in the drive groove 12. After the first motor 18 is started by the controller 20, the first worm 13 drives the two meshing first worm gears 14 to rotate synchronously, thereby causing the two bidirectional threaded rods 6 fixed to the first worm gears 14 to rotate synchronously. When it is necessary to adjust the front and rear spacing of the positioning wheel 11... During adjustment, the controller 20 starts the first motor 18, which in turn drives the first worm gear 13 in the drive groove 12 to rotate. This causes the two first worm wheels 14 meshing with the first worm gear 13 to rotate synchronously, thereby driving the two bidirectional threaded rods 6 to rotate synchronously between the front and rear inner walls of the hollow feeding table 3. This causes the two movable seats 7 threaded on them to slide in opposite directions, adjusting the front and rear distance of the positioning wheels 11 to accommodate plates of different widths. When there is a slight deviation between the material discharge position and the inlet of the subsequent processing equipment, the controller 20 starts the second motor 19. The second motor 19 drives the second worm gear 16 in the drive box 15 to rotate. The two meshing second worm wheels 17 drive the calibration screw 9 to rotate, causing the calibration slider 10 threaded on it to slide along the calibration groove 8.This, in turn, drives the positioning wheel 11 to move laterally and adjust the material discharge position. The entire system can adapt to materials of various widths without requiring component replacement. Furthermore, the lateral adjustment of the positioning wheel 11 can resolve minor deviations, reducing debugging time. Two linkage shafts 29 and linkage sleeves 28 are rotatably connected to opposite ends of the two moving seats 7. Both linkage shafts 29 are slidably disposed within their respective linkage sleeves 28. One end of each linkage shaft 29 and linkage sleeve 28 passes through the corresponding moving seat 7 and is fixedly connected to the corresponding calibration screw 9. Two linkage blocks 31 are fixedly connected to the outer walls of both linkage shafts 29. Two linkage grooves 30 are formed on the inner walls of both linkage sleeves 28, and multiple linkage blocks 31 slide within their respective linkage grooves 30. When the two moving seats 7 slide along the bidirectional threaded rod 6 to adjust the spacing, the linkage shaft 29 driven by one moving seat 7 will slide axially within the linkage sleeve 28 of the other moving seat 7. The linkage blocks 31 on the outer wall of the linkage shaft 29 always slide within the linkage grooves 30 on the inner wall of the linkage sleeve 28, thus ensuring proper calibration. The linkage structure between the lead screws 9 can adapt to the adjustment of the spacing of the moving seat 7. After the moving seat 7 is adjusted, when the second worm gear 17 controls the rotation of the corresponding calibration lead screw 9, the linkage structure causes the other calibration lead screw 9 to rotate. A second worm gear 16 is rotatably connected between the inner walls of both sides of the drive box 15. Two second worm gears 17 are rotatably connected between the front and rear inner walls of the drive box 15. Both second worm gears 17 mesh with the second worm gear 16. One end of each of the two calibration lead screws 9 near the drive box 15 passes through the corresponding moving seat 7 and the drive box 15 and is fixedly connected to the corresponding second worm gear 17. The output end of the second motor 19 passes through the drive box 15 and is fixedly connected to the second worm gear 16. The second motor 19 is electrically connected to the controller 20. The output end of the second motor 19 passes through the drive box 15 and is fixed to the second worm gear 16 inside the box. After the controller 20 starts the second motor 19, the second worm gear 16 drives the two meshing second worm gears 17 to rotate synchronously, causing the calibration lead screw 9 fixed to the second worm gear 17 and near the drive box 15 to rotate.

[0036] Reference Figure 2 and Figure 3The height adjustment component 5 includes two lifting threaded rods 22, both of which are rotatably connected to the support base 1. Lifting sleeves 23 are threaded onto the outer walls of both lifting threaded rods 22, and both lifting sleeves 23 are fixedly connected to the hollow feeding table 3. A transmission groove 24 is provided inside the support base 1. A third worm gear 25 is rotatably connected between the inner walls of both sides of the transmission groove 24. Two third worm wheels 26 are rotatably connected between the upper and lower inner walls of the transmission groove 24. A third motor 27 is fixedly installed on one side of the support base 1. Both third worm wheels 26 mesh with the third worm gear 25. The lower ends of both lifting threaded rods 22 penetrate the support base 1 and are fixedly connected to the corresponding third worm wheel 26. The output end of the third motor 27 penetrates the support base 1 and is fixedly connected to the third worm gear 25. 7 is electrically connected to the controller 20. After the controller 20 starts the third motor 27, the third worm 25 will rotate, which will cause the two third worm wheels 26 to rotate, thereby causing the corresponding lifting threaded rod 22 to rotate. When it is necessary to adjust the height of the hollow feeding table 3, the controller 20 starts the third motor 27, which will drive the third worm 25 in the transmission groove 24 of the support seat 1 to rotate, thereby causing the two third worm wheels 26 meshing with the third worm 25 to rotate synchronously, driving the two lifting threaded rods 22 to rotate on the support seat 1, so that the threaded lifting sleeve 23 drives the hollow feeding table 3 and the adjustable positioning component 4 to rise and fall as a whole. Thus, the height of the feeding table can be flexibly adjusted according to the inlet height of the subsequent processing equipment without modifying the processing equipment, improving adaptability.

[0037] Working Principle: When using this feeding table with material positioning function, if it is necessary to adapt to materials of different widths, the first motor 18 can be started by the controller 20. The output end of the first motor 18 drives the first worm gear 13 in the drive groove 12 inside the hollow feeding table 3 to rotate. The two first worm wheels 14 meshing with the first worm gear 13 rotate synchronously, thereby driving the two bidirectional threaded rods 6 to rotate synchronously between the front and rear inner walls of the hollow feeding table 3. This causes the two moving seats 7, which are threaded on the bidirectional threaded rods 6, to slide towards or in opposite directions. The front and rear distance of the positioning wheel 11 at the upper end of the moving seat 7 is adjusted to fit the width of the material. During this process, the linkage shaft 29 at one end of the two moving seats 7 will slide axially in the linkage sleeve 28, and the linkage block 31 on the outer wall of the linkage shaft 29 will always slide in the linkage groove 30 on the inner wall of the linkage sleeve 28. This ensures that the linkage structure of the calibration screw 9 adapts to the changes when the distance between the moving seats 7 is adjusted. When there is a slight difference between the material outlet position and the inlet of the subsequent processing equipment... When a deviation occurs, the controller 20 starts the second motor 19, which drives the second worm 16 in the drive box 15 to rotate. The two meshing second worm wheels 17 drive the calibration screw 9 near the drive box 15 to rotate. Then, through the transmission of the linkage shaft 29 and the linkage sleeve 28, the other calibration screw 9 rotates synchronously, causing the calibration slider 10 threaded on the calibration screw 9 to slide along the calibration groove 8. This, in turn, drives the positioning wheel 11 to move laterally to adjust the material discharge position. If it is necessary to adapt to the inlet height of the subsequent processing equipment, the controller 20 starts the third motor 27, which drives the third worm 25 in the transmission groove 24 inside the support base 1 to rotate. The two third worm wheels 26 meshing with the third worm 25 rotate synchronously, driving the two lifting threaded rods 22 to rotate on the support base 1. This causes the lifting sleeve 23 threaded on the lifting threaded rods 22 to drive the hollow feeding table 3 and the adjustable positioning assembly 4 to rise and fall as a whole, ultimately achieving stable material conveying and equipment adaptation.
