[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] When the shot blasting machine is in use, it needs the assistance of external equipment to complete the loading process of the workpiece and the unloading process after cleaning. However, the current equipment cannot perform loading and unloading operations at the same time. The workpiece on the material transport platform needs to be unloaded first. Only after unloading is completed can a new round of loading operation be carried out, and then the material transport platform is driven to transport the workpiece to the shot blasting machine. This process causes the shot blasting machine to be down for a long time, which is time-consuming and reduces production efficiency.

[0035] To solve the defects in the loading and unloading process of the above equipment, please refer to Figure 1-Figure 6 The utility model provides a loading and unloading structure for a shot blasting machine, which can simultaneously complete the loading and unloading operations of the workpiece, can effectively reduce the loading and unloading time of the workpiece, thereby reducing the downtime of the shot blasting machine during operation, thereby improving production efficiency. The device is based on a base 1, and a shot blasting machine body 2, a loading and unloading mechanism 3 and a material box 4 are sequentially arranged on the top of the base 1. The loading and unloading mechanism 3 can be used to load and unload the workpiece. The loading and unloading mechanism 3 includes a round table 31, and a bracket 32 ​​is rotatably installed on the top of the round table 31. A stepping motor (not shown in the figure) for driving the bracket 32 ​​to rotate is installed inside the round table 31. Material transporting parts 33 are arranged on both sides of the bracket 32, and a driving part 34 for driving the two groups of material transporting parts 33 to slide in opposite directions is arranged on the top of the bracket 32. The two groups of material transporting parts 33 are not at the same height. One group of material transporting parts 33 performs loading operation, and the other group of material transporting parts 33 performs unloading operation. The driving part 34 can drive the two groups of material transporting parts 33 to work alternately, which can effectively reduce the loading and unloading time of the workpiece, shorten the downtime of the shot blasting machine body 2, and improve production efficiency.

[0036] The support 331 is provided with a slide plate 331 which is slidably mounted on the side of the bracket 32, and a rotating shaft 332 is rotatably mounted inside the slide plate 331. The outside of the rotating shaft 332 is fixedly connected to a transport platform 333. The transport platform 333 is used to carry the workpiece. The outside of the bracket 32 ​​is symmetrically provided with blocking members 37 for controlling the tilting of the transport platform 333 at a specified height. When the transport platform 333 runs to the blocking member 37, the blocking member 37 can control the transport platform 333 to tilt gradually, so that the workpiece on the transport platform 333 can slide automatically. At this time, the workpiece to be processed on the high transport platform 333 can slide into the base 1, and the workpiece processed on the low transport platform 333 can slide into the material box 4, thereby realizing automatic loading and unloading of the workpiece.

[0037] In order to realize the reverse sliding of the two groups of material transport platforms 333, the following arrangement is specially made, wherein the two screw rods 341 are rotatably installed on both sides of the bracket 32 ​​respectively, the two slide plates 331 are threadedly installed on the outside of the two screw rods 341 respectively, and the two slide plates 331 are arranged in different horizontal planes, and the threads on the outside of the two screw rods 341 have the same rotation direction. When the two screw rods 341 rotate in opposite directions, the two slide plates 331 can be driven to slide in the opposite direction. When one material transport platform 333 rises, the other material transport platform 333 can fall, thereby realizing the alternating operation of the two material transport platforms 333.

[0038] In order to drive the two screw rods 341 to rotate in opposite directions, refer to Figure 2-Figure 4 As shown, the upper ends of the two screw rods 341 pass through the bracket 32 ​​and are fixedly connected to gear one 342. A bracket 345 is installed at the center of the top of the bracket 32. A servo motor 343 is installed on the top of the bracket 345. The output end of the servo motor 343 passes through the bracket 345 and is fixedly connected to gear two 344. Gear two 344 is meshed with the two gear ones 342. Driving the servo motor 343 can drive gear two 344 to rotate. The rotation of gear two 344 drives the two gear ones 342 to reverse. The reverse of the two gear ones 342 can drive the two screw rods 341 to reverse, thereby realizing the reverse sliding of the two material transport platforms 333.

[0039] When the two material transport platforms 333 slide to the specified height, it is necessary to load and unload the workpieces on the two material transport platforms 333 respectively. In order to realize automatic loading and unloading of the material transport platforms 333, a lower slide frame 371 and an upper slide frame 372 are set. The interior of the bracket 32 ​​is provided with a slide groove 375 for the lower slide frame 371 and the upper slide frame 372 to slide. The four corners of the lower slide frame 371 are fixedly connected to a rack 1 373, and the four corners of the upper slide frame 372 are fixedly connected to a rack 2 374. The teeth of the rack 1 373 and the rack 2 374 face opposite directions. Both ends of the rotating shaft 332 pass through the slide plate 331 and are fixedly connected to a spur gear 377. The spur gear 377, the rack 1 373, and the rack 2 374 are used in combination. When the slide plates 331 on both sides drive the two sets of spur gears 377 to slide to the rack 1 373 and the rack 2 374 respectively, When the rack 374 is at the position, due to the action of the rack 1 373 and the rack 2 374, as the slide plate 331 slides, the spur gear 377 can be driven to rotate, and the rotation of the two sets of spur gears 377 drives the rotating shaft 332 to rotate. The rotation of the rotating shaft 332 can drive the two transport platforms 333 to tilt to both sides, and then the workpiece can slide off the transport platform 333 by its own gravity. It should be noted that an elastic sleeve is arranged between the end of the rotating shaft 332 and the slide plate 331, and the elastic sleeve is used to increase the friction between the rotating shaft 332 and the slide plate 331, so as to improve the stability of the transport platform 333 and ensure that when the workpiece is placed on the transport platform 333, the transport platform 333 will not be tilted due to its gravity, and the rotating shaft 332 can be driven to rotate only through the meshing action of the rack 1 373, the rack 2 374 and the spur gear 377.

[0040] In actual processing, shot blasting machine bodies 2 of different specifications may need to be used, and the feed port heights of shot blasting machine bodies 2 of different specifications are also different. In order to make the loading and unloading mechanism 3 adapt to feed ports of different heights, it is necessary to adjust the height of the blocking member 37. Therefore, both ends of the lower sliding frame 371 and the upper sliding frame 372 are threadedly installed with fastening bolts, and the middle part of the bracket 32 ​​is provided with a plurality of mounting holes 376 for installing fastening bolts. The plurality of mounting holes 376 are equidistantly distributed longitudinally, so that the material transport platform 333 can be tilted to unload materials at a specified height.

[0041] Reference Figure 2 and Figure 5 As shown, a fall prevention bar 334 is fixedly installed on the top of the transport platform 333 to prevent the workpiece from falling, which can prevent the workpiece from falling from both sides of the transport platform 333. A telescopic leg 38 is installed at the bottom of the round table 31 to adjust the height of the round table 31, which is convenient for adjusting the overall height of the bracket 32 ​​and is suitable for shot blasting machine bodies 2 of different specifications.

[0042] The specific implementation process of this embodiment is as follows: when the shot blasting machine body 2 is working, the staff adds the workpiece to be processed to the low material transport platform 333 outside the shot blasting machine body 2. After the workpiece inside the shot blasting machine body 2 is processed, the driving member 34 drives the two material transport platforms 333 to slide in the opposite direction, and the outer material transport platform 333 drives the workpiece to rise, and drives the workpiece to be processed to a height close to the top of the material bin of the shot blasting machine body 2 to stop, and at the same time the inner material transport platform 333 descends, and the processed workpiece is sent from the shot blasting machine body 2 to the inner material transport platform 333, and the driving member 34 drives the two material transport platforms 333 to slide in the opposite direction. After the bracket 32 ​​rotates 180 degrees and the two sets of material transport platforms 333 exchange positions, the driving member 34 drives the two material transport platforms 333 to continue to slide in the opposite direction. Due to the action of the blocking member 37, the two material transport platforms 333 can be driven to tilt downward, so that the workpiece to be processed on the inner high material transport platform 333 falls into the shot blasting machine body 2, and at the same time, the processed workpiece on the outer low material transport platform 333 falls into the material box 4, so that the equipment can be loaded and unloaded at the same time. Such a cycle can effectively shorten the downtime of the shot blasting machine body 2 and improve production efficiency.

[0043] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
