[0022] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-7 The embodiment provides a technical scheme: an automatic pressing equipment for high-strength refractory brick production, comprising a frame body 1, the front end of the frame body 1 is provided with a refractory brick pressing mold 2, the movable die plate of the refractory brick pressing mold 2 is arranged at the telescopic end terminal of the electro-hydraulic push rod on the upper end of the frame body 1, the fixed die plate of the refractory brick pressing mold 2 is arranged on the bottom wall of the frame body 1, and the automatic pressing equipment further comprises a self-discharging mechanism 3.

[0024] The self-discharging mechanism 3 comprises a rotating column 31, a moving frame 32 and a clamping plate 33. The rotating column 31 is rotationally connected between the upper and lower inner walls of the frame body 1. The outer arc surface of the rotating column 31 is uniformly provided with the moving frame 32. The three moving frames 32 are annularly distributed with the rotating column 31 as the center. The moving frame 32 is located on the upper surface of the fixed die plate of the refractory brick pressing die 2. The inner part of the moving frame 32 is slidably connected with the clamping plate 33. The rotating column 31 is in transmission connection with the movable die plate of the refractory brick pressing die 2. The high-strength refractory brick after pressing will enter between the two clamping plates 33 in the same moving frame 32 after being ejected. The high-strength refractory brick is clamped by the clamping plate 33. The moving frame 32 is rotated by the rotating column 31 to transfer the high-strength refractory brick to the discharging position. The self-discharging mechanism 3 further comprises a clamping assembly 34. The clamping assembly 34 comprises a sliding column 341, an adjusting plate 342 and a spring 343. The sliding column 341 is slidably connected in the sliding hole of the left and right inner walls of the moving frame 32, respectively. The clamping plate 33 is arranged at the end of the sliding column 341 close to the center of the adjacent moving frame 32. The end of the sliding column 341 away from the center of the adjacent moving frame 32 is provided with the adjusting plate 342. The spring 343 is arranged between the adjusting plate 342 and the moving frame 32. The spring 343 is movably sleeved on the outer arc surface of the sliding column 341. The self-discharging mechanism 3 further comprises a top column 344. The top column 344 is arranged on the lower surface of the movable die plate of the refractory brick pressing die 2. The lower end of the top column 344 penetrates through the accommodation hole on the surface of the moving frame 32 and is in cooperation with the inclined surface of the adjusting plate 342. Before the movable die plate moves downward into the moving frame 32, the top column 344 will penetrate through the accommodation hole on the surface of the moving frame 32. The semicircular end of the top column 344 applies a downward force to the inclined surface of the adjusting plate 342 to overcome the elastic force of the spring 343, thereby pushing the sliding column 341 to slide and driving the two clamping plates 33 in the same moving frame 32 to relatively separate from each other to provide space for the downward movement of the movable die plate. With the upward movement of the top column 344, the two clamping plates 33 in the same moving frame 32 are relatively close to each other under the elastic force of the spring 343 to clamp the high-strength refractory brick. The self-discharging mechanism 3 further comprises a transmission assembly 35.

The rear end of the rotating shaft of the half gear 353 is provided with the bevel gear two 352. The bevel gear two 352 is in meshing connection with the bevel gear one 351. The rack plate one 354 and the rack plate two 355 are arranged on the surface of the movable die plate of the refractory brick pressing die 2. The rack plate one 354 and the rack plate two 355 are in cooperation with the half gear 353. When the movable die plate moves upward, only the rack plate two 355 is in meshing connection with the teeth of the half gear 353. The tooth ratio of the rack plate two 355 and the half gear 353 is one to one. The half gear 353 and the bevel gear two 352 are driven to rotate half a circle under the influence of the tooth ratio of the rack plate two 355 and the half gear 353. The bevel gear two 352 is in meshing connection with the bevel gear one 351.The bevel gear two 352 and the bevel gear one 351 are affected by the tooth ratio of the bevel gear two 352 and the bevel gear one 351, and the tooth ratio of the bevel gear two 352 and the bevel gear one 351 is one to three, so that the bevel gear one 351 drives the rotating column 31 to rotate one sixth of a circle. When the movable die plate moves downward, only the rack plate one 354 and the half gear 353 are engaged, and the tooth ratio of the rack plate one 354 and the half gear 353 is one to one. Affected by the tooth ratio of the rack plate one 354 and the half gear 353, the half gear 353 and the bevel gear two 352 are driven to continue rotating half a circle, and the rotating column 31 continues to rotate one sixth of a circle, so that the moving frame 32 rotates 120 degrees in total, switches the next moving frame 32 to be vertically coincident with the mold, and at the same time, the pressed high-strength refractory bricks are transferred to the discharging position. The discharging mechanism 3 further comprises a limiting assembly 36, the limiting assembly 36 comprising a limiting groove 361, a limiting column 362 and a limiting spring 363. The limiting groove 361 is arranged on the outer arc surface of the rotating column 31, and the limiting column 362 is slidably connected to the middle part of the vertical plate two of the top wall of the frame body 1. The limiting spring 363 is arranged between the limiting disc at the end of the limiting column 362 and the vertical plate two of the frame body 1. The limiting spring 363 is movably sleeved on the outer arc surface of the limiting column 362. The semicircular end of the limiting column 362 is inserted into the adjacent limiting groove 361. During the rotating process of the rotating column 31, the elastic force of the limiting spring 363 is overcome, the limiting column 362 is pushed to slide, and the semicircular end of the limiting column 362 is separated from the inside of the limiting groove 361. When the rotating column 31 stops rotating, the semicircular end of the limiting column 362 is inserted into the limiting groove 361 under the action of the elastic force of the limiting spring 363, so as to limit the rotation of the rotating column 31 and keep the accuracy of the adjusting angle of the rotating column 31. The discharging mechanism 3 further comprises an unloading top column 37, which is arranged on the left end of the movable die plate of the refractory brick pressing mold 2. When the high-strength refractory bricks are transferred to the discharging position, when the movable die plate moves downward again, the unloading top column 37 applies a force to the inclined surface of the adjusting plate 342 to cancel the clamping of the high-strength refractory bricks. It also comprises a rubber pad 4, which is arranged on the opposite inner side of the two clamping plates 33 in the same moving frame 32. The friction force of the surface of the clamping plate 33 is increased, and the firmness of the clamping of the high-strength refractory bricks is improved.
