The metal plate is arranged on the side close to the pressing plate, and the tetrafluoroethylene plate is arranged on the side away from the pressing plate.

[0010] Preferably, in the pressing plate structure of the discharging machine, the thickness of the metal plate is 5-8 mm.

[0011] Preferably, in the pressing plate structure of the discharging machine, the thickness of the tetrafluoroethylene plate is 15-30 mm.

[0012] Advantages of the utility model:

[0013] The pressing plate structure of the discharging machine of the present utility model can effectively reduce material accumulation by arranging a material plate on the surface of the pressing plate. At the same time, it can reduce the contact between the material and the pressing plate to prevent material contamination. After adding the material plate structure to the pressing plate, it can not only meet the requirements of the hygiene grade in the pharmaceutical and food industries, but also avoid the rapid temperature change of the material after contacting the metal pressing plate, which affects the flow performance of the material.

[0017] The present utility model will be further described below in conjunction with specific drawings and embodiments.

[0018] As Figures 1-3 , a pressing plate structure of a discharging machine includes a container 6. A pressing plate 2 with a clearance fit is arranged at the top of the container 6. A hydraulic cylinder 1 and an exhaust valve 3 are arranged on one surface of the pressing plate 2 away from the container 6. A material plate 5 is arranged on one surface of the pressing plate 2 close to the container 6.

[0019] A sealing ring 4 is arranged between the container 6 and the pressing plate 2; a groove matching with the sealing ring 4 is arranged on the outer periphery of the pressing plate 2; studs 7 are arranged on the material plate 5, and the studs 7 pass through the pressing plate 2 and the material plate 5 and the pressing plate 2 are fixed by nuts 8; the material plate 5 includes a metal plate 51 and a tetrafluoroethylene plate 52 arranged on the surface of the metal plate 51. The metal plate 51 is arranged on the side close to the pressing plate 2, and the tetrafluoroethylene plate 52 is arranged on the side away from the pressing plate 2; the thickness of the metal plate 51 is 5 - 8 mm, and the thickness of the tetrafluoroethylene plate 52 is 15 - 30 mm.

[0020] The studs welded on the material plate 5 pass through the pressing plate 2 and are locked with cap nuts on the upper surface of the pressing plate 2, which can effectively avoid material residue and foreign objects from entering the pressing plate structure; grooves are opened on the periphery of the pressing plate 2, and an O-ring 2 is placed to achieve a tight fit with the container 6, and the discharging is cleaner; inside the material plate 5 is a metal plate 51, and studs 7 are welded on the periphery to increase the strength and play a role in closely matching with the pressing plate; outside the material plate 5 is a tetrafluoroethylene plate 52 wrapped on the metal plate 51. The material of the metal plate 51 is 304 stainless steel. When discharging, the tetrafluoroethylene plate 52 contacts the material, which can meet the requirements of food hygiene grade; at the same time, it can effectively isolate the heat loss of the material caused by the contact between the metal pressing plate and the material, affecting the physical properties of the material.

[0021] Working principle of the utility model: The hydraulic cylinder 2 converts the potential energy of the hydraulic oil into kinetic energy to push the pressure plate 3 to move downward. There is a clearance fit between the pressure plate 2 and the container 6, and it is sealed by the sealing ring 4. After the sealing ring 4 contacts the container 6, the air inside the container 6 is discharged through the exhaust valve 3. The material plate 5 is installed on the lower surface of the pressure plate 2, contacts the material, and isolates the pressure plate from the material.
