DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 、 2 As shown in Figures 3, 4, and 5, the present utility model provides a technical solution: a mud cake peeling mechanism for a mud press, including: there are two support slide rails 1, and an extrusion forming clip is slidably placed on the top of the two support slide rails 1. A moving support plate 2 for support is fixedly connected to the side of the support slide rail 1, and the moving support plate 2 is of a T-shaped structure; a moving box 3 is slidably placed outside the moving support plate 2, and a driving part is arranged inside the moving box 3 for driving the moving box 3 to move along the moving support plate 2. The top of the moving box 3 is symmetrically rotatably connected with a first arc-shaped push rod 11 and a second arc-shaped push rod 12. An expansion electromagnet 13 is embedded at the end of the second arc-shaped push rod 12 for reciprocating expansion and contraction to achieve knocking vibration; a peeling assembly is placed outside the moving box 3, and the peeling assembly includes a separating shovel plate 9 and a cylinder 8 for driving the separating shovel plate 9 to lift and lower.

[0023] It should be noted that the present utility model is equipped with a PLC controller, and the motor, sensor, and solenoid valve of the cylinder are all electrically connected to the PLC controller. During operation, the driving part drives the moving box 3 to move outward along the support slide rail 1 towards the second arc-shaped push rod 12. When the top of the second arc-shaped push rod 12 contacts the side of the clip, under the action of pressure, the second arc-shaped push rod 12 moves downward. When the second arc-shaped push rod 12 is misaligned with the side of the clip, the return spring 15 drives the second arc-shaped push rod 12 to reset, and the driving part drives the moving box 3 to move in the reverse direction. At this time, the second arc-shaped push rod 12 separates the clip from the other clips. When the second arc-shaped push rod 12 contacts the clip, the pressure sensor 14 transmits a signal to the controller, and the controller controls the power-on and power-off time and the number of cycles by cooperating with a timer, thereby controlling the expansion electromagnet 13 to be energized reciprocally, and hitting the clip through reciprocating expansion and contraction to achieve knocking vibration, thereby accelerating the detachment of the mud cake. When the pressure sensor 14 detects a pressure signal, the cylinder 8 drives the separating shovel plate 9 to move downward, and the mud cake is separated from the clip through the separating shovel plate 9. When the moving box 3 moves the clip to a specified position, the first arc-shaped push rod 11 is pressed down by the cleaned clip in front, and then according to the preset program, the driving part drives the moving box 3 to move towards the direction of the second arc-shaped push rod 12 again, and the cyclic peeling is completed in this way.

[0024] Please refer to Figure 3 、 4As shown, the driving part includes a driving motor 17 fixedly connected inside the moving box 3. The output end of the driving motor 17 is fixedly connected with a driving gear 18. The outside of the driving gear 18 is meshed with a fixed rack 19, and the fixed rack 19 is fixedly connected to the bottom of the moving support plate 2.

[0025] It should be noted that when the moving box 3 of the present utility model needs to move, the driving motor 17 drives the driving gear 18 to rotate. The driving gear 18 meshes with the fixed rack 19. Under the reaction force, the driving motor 17 drives the moving box 3 to slide outside the moving support plate 2.

[0026] Please refer to Figure 3 、 4 As shown, a pressure sensor 14 is fixedly connected to one side of the second arc-shaped push rod 12. Pulling components are arranged below the second arc-shaped push rod 12 and the first arc-shaped push rod 11. The pulling component includes a lifting pull rod 16 rotatably connected to the bottoms of the second arc-shaped push rod 12 and the first arc-shaped push rod 11 respectively. The top of the moving box 3 is provided with a long hole for cooperating with the lifting pull rod 16. A return spring 15 is sleeved outside the lifting pull rod 16 and above the moving box 3. A limiting piece 10 is fixedly connected to the outside of the lifting pull rod 16 and inside the moving box 3. An electric telescopic rod 20 is fixedly connected inside the moving box 3. The output end of the electric telescopic rod 20 is fixedly connected with a pressing rod for driving the return spring 15 to move downward.

[0027] It should be noted that the pressure sensor 14 of the present utility model is used to detect whether the second arc-shaped push rod 12 contacts the clamping piece. When the second arc-shaped push rod 12 is squeezed downward, the second arc-shaped push rod 12 moves downward. While the second arc-shaped push rod 12 drives the lifting pull rod 16 to move inside the moving box 3, the return spring 15 is compressed. When the second arc-shaped push rod 12 separates from the top contact object, the return spring 15 drives the second arc-shaped push rod 12 to reset. When it is necessary to pull both the first arc-shaped push rod 11 and the second arc-shaped push rod 12 back to the top of the moving box 3, the telescopic end of the second arc-shaped push rod 12 retracts inward. The electric telescopic rod 20 drives the pressing rod to contact the bottom of the lifting pull rod 16, thereby pulling the lifting pull rod 16 downward, so that the second arc-shaped push rod 12 and the telescopic electromagnet 13 can perform corresponding downward flips.

[0028] Please refer to Figure 1 、 2 As shown in FIGS. 、5, the peeling component further includes a support tube 4 fixedly connected to the outside of the moving box 3. A lifting rod 5 is detachably installed inside the support tube 4. The top of the lifting rod 5 is fixedly connected with a cross bar 6. An adjustment slider 7 is adjustably installed in the middle of the cross bar 6. A cylinder 8 is fixedly connected to the top of the adjustment slider 7. A separation shovel plate 9 is fixedly connected to the output end of the cylinder 8. The separation shovel plate 9 is of an L-shaped structure, and a sliding rod slidably connected to the adjustment slider 7 is fixedly connected to the top of the separation shovel plate 9.

[0029] It should be noted that the lifting rod 5 of the present utility model is fixedly connected to the end of the support pipe 4 through a fastening bolt. A chute is provided in the middle of the cross bar 6. The adjustment slider 7 is slidably installed in the chute and fixed at a specified position through a fastening bolt. The adjustment slider 7 is fixed directly above the clamping piece. When the pressure of the pressure sensor 14 reaches the preset value, the cylinder 8 drives the separating shovel plate 9 to move downward. The side of the separating shovel plate 9 is in contact with the clamping piece, so as to separate the mud cake from the clamping piece.
