Description

Technical Field

[0001] This utility model relates to the technical field of shot blasting machines, and in particular to a dynamic height measuring mechanism for a roller conveyor shot blasting machine. Background Technology

[0002] Roller shot blasting machine is a type of shot blasting machine. During the cleaning process, an electrically controlled adjustable speed conveyor roller conveyor sends steel structural parts or steel materials into the blasting zone inside the cleaning machine chamber. All surfaces of the parts are subjected to strong and dense shot impacts and friction from different coordinate directions.

[0003] Existing roller shot blasting machines, such as the roller conveyor shot blasting machine disclosed in utility model patent application number 202422515404.6, mainly include a shot blasting box. Conveyor roller frames are symmetrically fixedly installed on both sides of the shot blasting box. A partition is fixedly installed inside the shot blasting box. A treatment chamber is arranged along one side of the partition inside the shot blasting box. A water distributor is arranged inside the treatment chamber of the shot blasting box. In use, the plate enters the treatment chamber of the shot blasting box through the conveyor roller frames. First, water is sprayed by the water distributor in conjunction with the inclined nozzles to wash away the dust and impurities on the surface of the plate.

[0004] However, when existing thick plate shot blasting machines clean steel plate shot, most of them place photoelectric sensors for detecting height at fixed intervals. Because of the spacing and relatively fixed position, the measurement error is large, which affects work efficiency and increases equipment operating costs and maintenance time. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dynamic height measuring mechanism for a roller shot blasting machine. The steel plate is conveyed forward, and the photoelectric mechanism reciprocates to emit photoelectric signals. The reflector reflects the photoelectric signals. The height of the steel plate is determined by detecting the distance at which the photoelectric signals are blocked. This allows the PLC to control the lifting micro-brake motors of the cleaning roller brush and the shot collection spiral in the cleaning chamber based on the value, thus achieving more precise height adjustment.

[0006] This utility model discloses a dynamic height measuring mechanism for a roller conveyor shot blasting machine, including the shot blasting machine itself; it also includes a photoelectric mechanism and a reflective mechanism. The photoelectric mechanism is installed on the left side of the shot blasting machine and emits photoelectric signals, while the reflective mechanism is installed on the right side of the shot blasting machine and reflects the photoelectric signals. The steel plate is conveyed forward, and the photoelectric mechanism reciprocates to emit photoelectric signals. The reflective mechanism reflects the photoelectric signals. The height of the steel plate is determined by detecting the distance at which the photoelectric signals are blocked. This allows the PLC to control the lifting and lowering micro-brake motors of the cleaning roller brush and the shot collection spiral in the cleaning chamber based on this value, achieving relatively precise height adjustment.

[0007] Preferably, the shot blasting machine includes a conveyor roller and a steel plate. The conveyor roller is installed on the shot blasting machine, and the steel plate is placed on the conveyor roller. The conveyor roller drives the steel plate forward.

[0008] Preferably, the photoelectric mechanism includes a first detection base, a servo motor, a lead screw module, and a photoelectric switch base. The first detection base is installed on the ground and located on the left side of the conveyor roller conveyor. The servo motor is installed on the first detection base, and its output end is connected to the input end of the lead screw module. The photoelectric switch base is slidably installed on the first detection base and connected to the lead screw module via a threaded transmission. When the servo motor is started, it drives the photoelectric switch base to move up and down within its stroke range through the lead screw module. The photoelectric switch base emits a photoelectric signal, which is blocked by a steel plate.

[0009] Preferably, the reflection mechanism includes a second detection base and a reflector. The second detection base is installed on the ground and located on the right side of the conveyor roller conveyor, opposite to the first detection base. The reflector is installed on the second detection base. When the reflector is blocked by the steel plate, it cannot receive a photoelectric signal. After moving away from the height of the steel plate, the reflector reads the signal again and then dynamically feeds back the height information. The PLC obtains the distance value measured by the photoelectric switch base, that is, the height of the steel plate. The PLC controls the lifting micro-brake motor of the cleaning roller brush and the shot collection auger in the cleaning chamber according to the value to achieve a relatively precise height adjustment.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the steel plate is conveyed forward, the photoelectric mechanism reciprocates to emit photoelectric signals, the reflection mechanism reflects the photoelectric signals, and the height of the steel plate is determined by detecting the distance at which the photoelectric signals are blocked. This allows the PLC to control the lifting micro-brake motors of the cleaning roller brush and the shot collection auger in the cleaning chamber according to the value, thereby achieving more precise height adjustment.

The conveyor roller 11 is installed on the shot blasting machine, and the steel plate 12 is placed on the conveyor roller 11. The photoelectric mechanism 02 is equipped with a first detection base 21, a servo motor 22, a lead screw module 23, and a photoelectric switch base 24. The first detection base 21 is equipped with... On the ground and located to the left of the conveyor roller 11, a servo motor 22 is mounted on the first detection base 21. The output end of the servo motor 22 is connected to the input end of the lead screw module 23. The photoelectric switch base 24 is slidably mounted on the first detection base 21 and connected to the lead screw module 23 via a threaded transmission. When it is working, firstly, the conveyor roller 11 drives the steel plate 12 to be conveyed forward, and the servo motor 22 is started. The servo motor 22 drives the photoelectric switch base 24 to move up and down within the stroke range through the lead screw module 23. The photoelectric switch base 24 emits photoelectric signals, and the steel plate 12 blocks the photoelectric signals.

[0015] Example 2 like Figures 1 to 4 As shown, this utility model discloses a dynamic height measuring mechanism for a roller shot blasting machine, based on embodiment 1.

The servo motor 22 drives the photoelectric switch base 24 to move up and down within the stroke range through the lead screw module 23. The photoelectric switch base 24 emits a photoelectric signal. The steel plate 12 blocks the photoelectric signal. The reflector 32 cannot obtain the photoelectric signal under the obstruction of the steel plate 12. After moving a distance equal to the height of the steel plate 12, the reflector 32 rereads the signal and then dynamically feeds back the height information. The PLC obtains the distance value measured by the photoelectric switch base 24, which is the height of the steel plate. The PLC controls the lifting micro-brake motors of the cleaning roller brush and the shot collection spiral in the cleaning chamber according to this value to achieve a more precise height adjustment.
