Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a roller-through type parts turning mechanism. Background Art

[0002] Shot blasting machine, also known as sandblasting machine, is a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. Shot blasting machines are divided into drum type, chain plate type, hanging type, turntable type, through type shot blasting machine, etc. according to the structure of the casting carrier. Its grinding methods include centrifugal grinding method, water vortex grinding method, rotary grinding method, etc., which are first used in the foundry industry to remove sand and oxide scale on the surface of cast steel and cast iron parts.

[0003] The through-type shot blasting machine is mainly composed of a horizontally placed machine base and a shot blasting chamber arranged on the machine base. The machine base is provided with a component for conveying materials, and a number of shot blasting machines are arranged outside the shot blasting chamber. When the conveying component conveys the material to the shot blasting chamber, the material is shot blasted by the cooperation of a number of shot blasting machines. At the same time, in order to improve the degree of automation, the common through-type shot blasting machine is also provided with a steel shot collection component, an elevator, a separator, a dust removal component, etc. In order to improve the shot blasting efficiency of the material, the through-type shot blasting machine usually sets upper and lower corresponding shot blasting machines on the shot blasting chamber to achieve the purpose of shot blasting the upper and lower surfaces of the material in one operation. However, this treatment method is not suitable for thin plate materials. Since such materials have a light weight, when the bottom surface is shot blasted from bottom to top, it is easy to cause material displacement, and even cause the material to flip in the shot blasting chamber, affecting the shot blasting effect. At the same time, there are certain safety hazards. For this reason, we propose a roller through-type part flipping mechanism to solve the above problems. Utility Model Content

[0026] See also Figure 3 , 5 6. The flip assembly 26 includes a mounting back plate 261, a driving assembly 262, a transmission shaft 263, a flip plate 264, an electromagnet 265, and a conductive slip ring 266. The mounting back plate 261 is fixedly mounted on the mounting frame 21 by bolts. The driving assembly 262 is fixedly mounted on the top of the mounting back plate 261. The driving assembly 262 is composed of a servo motor and a reducer, which can provide power for the rotation of the transmission shaft 263. The transmission shaft 263 is movably mounted on the mounting back plate 261. The driving assembly 262 and the transmission shaft 263 are transmitted through a sprocket structure. The driving assembly 262 can drive the corresponding transmission shaft 263 to rotate through the sprocket structure to realize the flipping of the material. The driving assembly 262 is electrically connected to the electric control cabinet 10. The electric control cabinet 10 can control the driving assembly 262 according to the detection signal of the induction switch 27, thereby realizing the flipping of the material.

[0027] The outside of the transmission shaft 263 is fixedly connected with a plurality of mirror-distributed flip plates 264, and the plurality of flip plates 264 are distributed in two groups. The flip plates 264 are driven by the transmission shaft 263 to rotate, so as to realize flipping of the material, and an electromagnet 265 is fixedly installed on one side of the flip plate 264. The flip plates 264 and the conveying rollers 22 are staggered to avoid interference between the flip plates 264 and the conveying rollers 22. A conductive slip ring 266 is mounted on one end of the transmission shaft 263 close to the mounting back plate 261. When the transmission shaft 263 rotates, the electromagnet 265 can always be powered by the conductive slip ring 266 to ensure the effectiveness of the electromagnet 265. The electromagnet 265 is electrically connected to the electric control cabinet 10 through the conductive slip ring 266 to ensure that the electric control cabinet 10 can control the start and stop of the electromagnet 265 according to the rotation state of the flip plate 264, thereby realizing the adsorption and release of the material.

[0028] The induction switch 27 is located between the feeding area 24 and the return area 25. The induction switch 27 is located at one end of the transmission shaft 263 away from the mounting back plate 261. When the induction switch 27 initially detects the material, the surface material moves to the position of the flip plate 264. When the detection signal of the induction switch 27 disappears, the surface material completely enters the position of the flip plate 264. The induction switch 27 is a photoelectric switch, which is a common existing technology at present. Schneider's products can be selected. The detection height of the induction switch 27 is 0.5-1 cm higher than one end of the inner side of the conveying roller 22, ensuring that the induction switch 27 can effectively detect the material on the feeding area 24 and ensure that the material can be completely moved to the flip plate 264 for flipping. The induction switch 27 is electrically connected to the electric control cabinet 10. The material on the feeding area 24 is detected by the induction switch 27, and the signal is transmitted to the electric control cabinet 10. When the induction switch 27 initially detects the material, the surface material moves to the position of the flip plate 264. When the detection signal of the induction switch 27 disappears, the surface material completely enters the position of the flip plate 264.

[0029] In summary, when the roller-through part turning mechanism is in use, during the shot blasting operation on the material, the power components 23 of the feed area 24 and the return area 25 drive the corresponding conveying rollers 22 to rotate through the sprocket structure to convey the material, and the conveying rollers 22 of the feed area 24 and the return area 25 rotate in opposite directions. The electric control cabinet 10 controls the loading and unloading manipulators 9 on one side of the feed area 24 to place the material to be processed on the feed area 24, and convey the material to the shot blasting chamber 3 along the feed area 24. The electric control cabinet 10 controls the shot blasting machine 4 to start the shot blasting on the front of the material during the material transportation. At the same time, during the shot blasting operation, the electric control cabinet 10 controls the dust removal component 8 to start to process the smoke generated by the shot blasting, and controls the steel shot collection component 7 to start to collect the steel shots, and controls the bucket elevator 5 and the steel shot separation component 6 to start. The bucket elevator 5 conveys the collected steel shots to the steel shot separation component 6. The steel shot separation component 6 The steel shot is separated from the impurities, and the steel shot is put back into the shot blasting machine 4 so that the steel shot can be recycled. The material position is detected by the induction switch 27, and the signal is transmitted to the electric control cabinet 10. When the induction switch 27 initially detects the material, the surface material moves to the position of the flip plate 264. When the detection signal of the induction switch 27 disappears, the surface material completely enters the position of the flip plate 264. At this time, the electric control cabinet 10 controls the electromagnet 265 to start adsorbing the material, and notifies the control drive component 262 to drive the transmission shaft 263 and the flip plate 264 to flip. After the flip is completed, the electric control cabinet 10 controls the electromagnet 265 to cut off the power, flip the material to the return material area 25, and the conveying roller 22 on the return material area 25 conveys the material to the shot blasting chamber 3 again, and the back of the material is shot blasted. The electric control cabinet 10 controls the loading and unloading manipulator 9 on one side of the return material area 25 to take out the material after the shot blasting.
