The feeding frame 4 is fixedly connected with the telescopic shaft of the electric push rod 3, and the feeding frame 4 is a rectangular frame matched with the forming hole plate 5.

The feeding frame 4 is located between the two far ends of the material blocking frame 8 and is in sliding contact with the two far ends of the material blocking frame 8.
[0035] Working principle: when the device is used for catalyst carrier forming, the raw material for catalyst carrier forming is first loaded into the feeding frame 4. Then the electric push rod 3 is started, the telescopic shaft of the electric push rod 3 is extended and pushes the feeding frame 4 to slide to the right. When the feeding frame 4 slides to the top of the forming hole plate 5, all the perforations on the forming hole plate 5 are filled with raw material. In this process, the inner wall of the perforation and the top end surface of the pressure rod on the lower mold 15 together form a slot upwardly, and the slot is filled with raw material.
[0036] Then the telescopic shaft of the electric push rod 3 is retracted and drives the feeding frame 4 to slide back. In this process, the feeding frame 4 pushes away the excess raw material on the top plane of the forming hole plate 5.
[0037] Then the hydraulic cylinder 2 is started, the telescopic shaft of the hydraulic cylinder 2 is extended downwardly and drives the mounting plate 10 to move downwardly, the mounting plate 10 drives the upper mold 14 to move downwardly, and the upper mold 14 drives the pressure rod at the bottom to be inserted into the perforation of the forming hole plate 5. In this process, the mounting plate 10 slides downwardly along the pull rod 9, and the pressure rod at the bottom of the upper mold 14 and the pressure rod on the top of the lower mold 15 extrude the raw material in the slot to form the catalyst carrier into a block.
[0038] After the extrusion is completed, the telescopic shaft of the hydraulic cylinder 2 is retracted upwards and drives the mounting plate 10 to move upwards, the mounting plate 10 drives the upper die 14 to move upwards, the upper die 14 drives the bottom pressing rod to move out of the perforation of the forming hole plate 5. With the continuous upward movement of the mounting plate 10, the mounting plate 10 gradually contacts and abuts against all the limiting caps 16. Then, the mounting plate 10 drives all the limiting caps 16 to move upwards synchronously, and each limiting cap 16 drives the corresponding pull rod 9 to move upwards. At this time, all the pull rods 9 simultaneously drive the lower die 15 to move upwards, and the lower die 15 stretches all the return springs 11. At the same time, the lower die 15 drives all the pressing rods at the top to push the formed catalyst carrier in the corresponding storage groove upwards. When the top end surface of the pressing rod at the top of the lower die 15 is flush with the top plane of the forming hole plate 5, the hydraulic cylinder 2 is stopped.
[0039] After that, the electric push rod 3 is started again, and the telescopic shaft of the electric push rod 3 drives the feeding frame 4 to slide close to the top opening of the flow channel 6. In this process, the right side frame of the feeding frame 4 gradually contacts and pushes the formed catalyst carrier to move to the top opening of the flow channel 6. The formed catalyst carrier moves to the top opening of the flow channel 6 and flows into the collection box 7 through the flow channel 6.
[0040] Then the telescopic shaft of the electric push rod 3 drives the feeding frame 4 to slide back. After the feeding frame 4 slides back, the hydraulic cylinder 2 is extended downwards again and drives the mounting plate 10 to move downwards. At this time, all the limiting caps 16 are relatively stationary with the mounting plate 10 under the elastic force of the return springs 11. At the same time, the lower die 15 moves downwards and drives the bottom limiting rod 12 to move downwards. When all the limiting rods 12 contact and abut against the groove bottom of the forming groove 13, the lower die 15, all the pull rods 9 and all the limiting caps 16 stop moving. At this time, the hydraulic cylinder 2 is stopped, and the electric push rod 3 is started again.
[0041] After that, the feeding frame 4 pushes the raw material into the perforation of the forming hole plate 5 again.
[0042] Finally, the above operation is repeated for uninterrupted production.
[0043] Finally, it should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
