Description

Technical Field

[0001] This utility model relates to the field of through shot blasting machine technology, specifically a workpiece flipping mechanism for through shot blasting machines. Background Technology

[0002] Through-feed shot blasting machine is a continuous conveying surface treatment equipment, mainly used for surface cleaning and strengthening of metal materials such as steel, castings, and forgings. Its core working principle is to remove oxide scale, rust layer and impurities from the surface of the workpiece by high-speed shot impact, while achieving surface strengthening.

[0003] The workpiece tilting mechanism used in a through-feed shot blasting machine is a key component of the shot blasting machine system. During operation, the material to be tilted is first placed into the machine body, and then the tilting device is rotated by a mechanical arm or hydraulic device to tilt the material to the tilting position. The material is unloaded by vibration, and finally, a safety protection device is used to achieve stable tilting. However, when using the existing workpiece tilting mechanism, the workpiece is not fully unloaded during unloading, and some workpieces fall into the rear half of the tilting hopper. As the tilting hopper returns to its original position, the workpieces are poured back into the material box. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece flipping mechanism for a through shot blasting machine, so as to solve the problem that when the workpiece flipping mechanism mentioned in the background art is used, the workpiece is not fully unloaded during unloading, and some workpieces fall into the rear half of the flipping hopper and are poured back into the material box as the flipping hopper returns to its original position.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A workpiece flipping mechanism for a through-feed shot blasting machine includes:

[0027] The frame includes a workpiece flipping assembly 1, and a hopper 11 is provided on the surface of the workpiece flipping assembly 1. Both the workpiece flipping assembly 1 and the hopper 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0028] The tilting unloading mechanism includes a protective groove 2, which is fixedly connected to the surface of the tilting hopper 11 to protect the internal structure. A drive cylinder 21 is installed inside the protective groove 2 to drive the rack plate 22 to move. The rack plate 22 is fixedly connected to the surface of the drive cylinder 21 to drive the sector-shaped toothed plate 24 to rotate. A first fixed shaft 23 is fixedly connected to the surface of the tilting hopper 11 to connect to a first connecting shaft 25. The sector-shaped toothed plate 24 is meshed with the surface of the rack plate 22 to connect to the first connecting shaft 25. The first connecting shaft 25 is fixedly connected to the surface of the sector-shaped toothed plate 24 to drive the unloading plate 26 to rotate. The unloading plate 26 is fixedly connected to the surface of the first connecting shaft 25 for rapid and sufficient unloading of the workpiece.

[0029] Furthermore, the rack plate 22 is internally connected to the protective groove 2 via the drive cylinder 21. When the drive cylinder 21 is activated, it drives the rack plate 22 to move, thereby causing the sector-shaped rack plate 24 to rotate.

[0030] Furthermore, the sector-shaped toothed plate 24 is rotatably connected to the surface of the rack plate 22 and the first fixed shaft 23. The sector-shaped toothed plate 24 rotates on the surface of the first fixed shaft 23 as the rack plate 22 moves, thereby driving the first connecting shaft 25 to rotate.

[0031] Furthermore, the first fixed shaft 23 is symmetrically distributed in two sets on the surface of the workpiece flipping assembly 1. The first connecting shaft 25 is rotatably connected to the surface of the first fixed shaft 23 through the sector tooth plate 24. The two sets of first fixed shafts 23 are respectively connected to the two ends of the first connecting shaft 25. The first connecting shaft 25 rotates on the surface of the first fixed shaft 23 as the sector tooth plate 24 rotates.

[0032] Furthermore, the feeding plate 26 is rotatably connected to the surface of the tilting hopper 11 via the first connecting shaft 25. The feeding plate 26 rotates on the surface of the tilting hopper 11 as the first connecting shaft 25 rotates, thereby enabling the subsequent workpieces to be fed quickly and fully.

[0033] Furthermore, the discharge guiding mechanism includes an adjusting groove 3, which is fixedly connected to the surface of the unloading plate 26 to protect the internal structure. An adjusting knob 31 is rotatably connected to the surface of the adjusting groove 3 to drive the worm gear 32 to rotate. The worm gear 32 is fixedly connected to the surface of the adjusting knob 31 to drive the worm wheel 34 to rotate. A second connecting shaft 33 is fixedly connected inside the adjusting groove 3 to connect the worm wheel 34. The worm gear 32 is meshed with the worm wheel 34 to drive the worm rack 35 to move. The worm rack 35 is meshed with the surface of the worm wheel 34 to drive one end of the retractable guide plate 36 to move by its own movement. The retractable guide plate 36 is hinged to the surface of the worm rack 35 to guide the discharged workpiece. A second fixing shaft 37 is fixedly connected to the surface of the unloading plate 26 to fix the other end of the retractable guide plate 36.

[0034] Furthermore, the worm 32 is rotatably connected to the inside of the adjusting knob 31 and the adjusting groove 3, and the worm wheel 34 is rotatably connected to the surface of the worm 32 and the second connecting shaft 33. Rotating the adjusting knob 31 drives the worm 32 to rotate, thereby driving the worm wheel 34 to rotate on the surface of the second connecting shaft 33. The worm 32 and the worm wheel 34 have a self-locking structure and will not rotate without the action of external force.

[0035] Furthermore, the worm gear 35 is movably connected to the surface of the worm wheel 34 and the adjusting groove 3, and the telescopic guide plate 36 is rotatably connected to the surface of the worm gear 35 and the second fixed shaft 37. The worm gear 35 moves on the surface of the adjusting groove 3 as the worm wheel 34 rotates, thereby pushing one end of the telescopic guide plate 36 to move, so that the entire telescopic guide plate 36 rotates on the surface of the second fixed shaft 37, thereby changing the workpiece discharge distance and preventing the workpiece from falling to the outside of the subsequent conveying structure.

[0036] Working principle: When using the workpiece flipping assembly 1, firstly, rotating the adjustment knob 31 drives the worm gear 32 to rotate, thereby driving the worm wheel 34 to rotate on the surface of the second connecting shaft 33. The worm gear 32 and worm wheel 34 are self-locking structures and will not rotate without external force. The worm rack 35 moves on the surface of the adjustment groove 3 following the rotation of the worm wheel 34, thereby pushing one end of the telescopic guide plate 36 to move, so that the telescopic guide plate 36 rotates on the surface of the second fixed shaft 37, thereby changing the workpiece discharge distance and preventing the workpiece from falling outside the subsequent conveying structure. After most of the workpieces are discharged, the drive cylinder 21 is activated to drive the rack plate 22 to move. The sector toothed plate 24 rotates on the surface of the first fixed shaft 23 following the movement of the rack plate 22. The first connecting shaft 25 rotates on the surface of the first fixed shaft 23 following the rotation of the sector toothed plate 24. The feeding plate 26 rotates on the surface of the flipping hopper 11 following the rotation of the first connecting shaft 25, thereby enabling the subsequent workpieces to be discharged quickly and fully.
