DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0024] like Figures 1 to 6 The automatic feeding device for mechanical processing shown in the figure comprises a bottom plate 1 and a transport frame 13, the transport frame 13 is rotatably connected with a transmission roller assembly 14, two groups of transmission roller assemblies 14 are provided, the two groups of transmission roller assemblies 14 are respectively located on the left and right sides of the transport frame 13, the two groups of transmission roller assemblies 14 are commonly connected with a transmission belt, the transport frame 13 is connected with a driving motor 21, the output shaft of the driving motor 21 is connected with the left transmission roller assembly 14, and the bottom plate 1 is connected with a bearing foot 2;

The base plate 1 is rotatably connected with a threaded rod 11. Two threaded rods 11 are provided. The two threaded rods 11 are respectively threadedly connected with the front and rear sides of the mounting frame 12. The threaded rod 11 is connected with a worm gear 9. The worm gear 9 is located on the inner side of the mounting groove 6. The base plate 1 is rotatably connected with a worm 8. The base plate 1 is connected with a servo motor 22. The output shaft of the servo motor 22 is connected with the worm gear 8, and the worm gear 8 is meshed with the worm gear 9. The lifting device is provided with two groups. The two groups of mounting frames 12 are rotatably connected with the left and right sides of the transport frame 13 respectively. The bottom right side of the transport frame 13 is connected with a fixed plate 18, and the fixed plate 18 is connected with an auxiliary sliding rod 19. The auxiliary sliding rod 19 is slidably connected with a movable square plate 20. The movable square plate 20 is in conflict with the fixed plate 18. The two groups of mounting frames 12 are respectively hinged with the transport frame 13 and the movable square plate.

[0026] The transport frame 13 is rotatably connected to an auxiliary roller 16, and the transmission belt is in conflict with the auxiliary roller 16. The bottom of the transport frame 13 is connected to a cleaning scraper 17, and the cleaning scraper 17 is in conflict with the transmission belt. The base plate 1 is detachably connected to a receiving hopper 7, and the receiving hopper 7 is located on the lower side of the cleaning scraper 17. The receiving hopper 7 can be directly placed on the base plate 1. The base plate 1 is connected to a cylinder 5, and the cylinder 5 is connected to a connecting plate 4, and the connecting plate 4 is connected to a universal wheel 3; the base plate 1 is connected to a protective frame 10, and the mounting frame 12 is slidably connected to the protective frame 10.

[0027] The specific implementation process is as follows:

[0028] The driving motor 21 drives the transmission roller assembly 14 to rotate, and then drives the transmission belt to rotate. The material transportation and loading can be completed through the transmission belt. The principle of the transmission roller assembly 14 driving the transmission belt to rotate is the principle of the transmission belt conveyor. This principle is an existing technology well known to practitioners in this field and will not be repeated here.

[0029] The following describes the lifting and lowering of the mounting bracket 12. The servo motor 22 drives the worm 8 to rotate, and the worm 8 drives the two sets of worm wheels 9 to rotate simultaneously, thereby causing the two threaded rods 11 to rotate simultaneously. The protection frame 10 limits the rotation of the mounting bracket 12 and protects the threaded rod 11 at the same time, thereby allowing the mounting bracket 12 to move upward or downward along the threaded rod 11 as the threaded rod 11 rotates.

[0030] When in use, the supporting foot 2 is grounded, and then the device is stably placed on the ground for use, and the driving motor 21 is started to drive the transmission belt to rotate to complete the transportation and loading of materials. While the transmission belt rotates, the impurities on the transmission belt are scraped off by the cleaning scraper 17 and collected in the receiving hopper 7, and the receiving hopper 7 can be directly lifted up later to complete the centralized processing of impurities; when it is necessary to adjust the transportation and loading height, the corresponding servo motor 22 can be controlled to adjust the height of the corresponding support frame to complete the adjustment of the height of the transport frame 13; the following is an explanation of the state of adjusting the transport frame 13 to the left lower and the right higher. First, the servo motor 22 on the right is controlled to drive the support frame on the right to move up. At this time, the support frame on the left The frame is fixed, and the upward movement of the right support frame will resist the moving square plate 20 and then the right side of the moving frame, thereby lifting the right side of the moving frame upward, so that the moving frame rotates counterclockwise with the hinge point between the left side of the moving frame and the left mounting frame 12 as the axis. The right mounting frame 12 is hinged to the moving block, so it can adapt to the rotation of the moving frame. At the same time, the moving block is slidably connected to the auxiliary slide bar 19. In conjunction with the rotation of the moving frame, the moving square plate 20 will slide along the auxiliary slide bar 19, thereby completing the adjustment of the left high and right low of the moving frame; similarly, the servo motors 22 at the corresponding positions can be started to adjust the heights of the left and right sides of the moving frame respectively, so as to use different loading and unloading heights to improve the practicality of the device.

[0031] When the device needs to be moved, the cylinder 5 is started to drive the connecting plate 4 to move downward, thereby making the universal wheel 3 grounded, and then the device can be quickly pushed to other positions for work, which is convenient to use.

[0032] The technical solution is provided with two sets of lifting devices. By rotating the worm 8, the height of the transmission belt 15 can be adjusted, thereby adjusting the height of the loading and transportation, which is convenient for the device to automatically load materials for workbenches or machines at different heights, thereby improving the flexibility of the device; a movable square plate 20 is slidably provided at one end of the transport frame 13, and one set of lifting devices is hinged to the movable square plate 20, so that the cooperation of the two sets of lifting devices can not only adjust the overall height of the loading device but also adjust the feeding angle of the loading device, that is, the device can complete inclined transportation, so that the loading device can be lower on one side and higher on the other side, thereby adapting to different loading heights and different unloading heights, greatly improving the applicability and practicality of the device, with a simple structure and easy operation; a cleaning scraper 17 is provided , the garbage attached to the transmission belt 15 can be scraped off and collected in a centralized manner through the material receiving hopper 7, so as to keep the transmission belt 15 clean and improve the use effect without frequent manual cleaning; the auxiliary roller 16 can improve the stability of the material moving on the transmission belt 15; the protection frame 10 can effectively protect the threaded rod 11 to prevent the threaded rod 11 from being exposed and easily deformed by external impact and affecting subsequent use; the cylinder 5 can control the lifting and lowering of the universal wheel 3, and the bearing foot 2 is grounded when the device is used normally, which improves the placement stability of the device and avoids the situation where the universal wheel 3 is easily damaged due to long-term grounding, so that the device can be stably placed and used, and is easy to move to adapt to different production lines, further improving the applicability of the device.

[0033] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
