Detailed implementation mode

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. The implementation modes of the present utility model include but are not limited to the following embodiments.

[0025] First embodiment:

[0026] As Figure 1-2 shown, the adjustable feed valve for epoxy resin preparation provided by the present utility model includes: an adjustable feed valve mechanism 100 and a feed valve assembly 200. The feed valve assembly 200 includes a feed tank 201. The two side ends of the feed tank 201 are connected and fixed to a first gate 212 and a second gate 213 through rotating guide columns 209. The rotating guide columns 209 can rotate on both sides of the feed tank 201. One ends of the first gate 212 and the second gate 213 are connected and fixed to the rotating guide columns 209 by welding. The outer sides of the rotating guide columns 209 are connected and fixed to a first semi-circular gear 210 and a second semi-circular gear 211 by welding. The teeth of the first semi-circular gear 210 and the second semi-circular gear 211 are mutually butted. One ends of the first gate 212 and the second gate 213 are connected and fixed to a rolling bearing 208 by screws. A connecting guide column 207 is connected through the inside of the rolling bearing 208. The connecting guide column 207 can rotate inside the rolling bearing 208. One end of the connecting guide column 207 is connected and fixed to a lifting guide column 206 by welding. The lifting guide column 206 is installed inside a lifting cylinder 205. One end of the lifting cylinder 205 is connected and fixed to a fixed block 203 through a movable bolt 204. In actual use, when the staff pours epoxy resin raw material particles into the feed tank 201 and pours them into the inside of the production preparation tank 101 through the leakage holes 215 of the feed tank 201 for further processing. By driving the lifting cylinder 205 to move the lifting guide column 206, when the lifting guide column 206 moves backward, and the first gate 212 and the second gate 213 rotate through the first semi-circular gear 210 and the second semi-circular gear 211, then the first gate 212 and the second gate 213 are opened. When the first semi-circular gear 210 and the second semi-circular gear 211 are adjusted and rotated, the opening angle of the first gate 212 and the second gate 213 can be adjusted, and the amount of epoxy resin raw material particles poured into the inside of the production preparation tank 101 can be controlled to be too much or too little, reducing problems such as too much epoxy resin raw material particles being poured into the production preparation tank 101.

[0027] In this embodiment, by using the gate, the semi-circular gear, the lifting guide post 206, the lifting cylinder 205, the rolling bearing 208, and the connecting guide post 207, the opening angle of the two gates can be accurately controlled by adjusting the semi-circular gear, so as to control the amount of raw materials entering the production preparation box 101 each time, ensuring the consistency and accuracy of the amount of raw materials during the processing. By controlling the opening and closing degree of the gate, the situation of excessive or insufficient raw materials caused by operational errors can be reduced, thus avoiding waste or quality problems during the production process, reducing the need for manual operation, improving the efficiency and speed of the feeding process, and at the same time reducing the dependence on operators.

[0028] Second Embodiment:

Through the protective plate 214, the contact and collision between the first gate 212 and the second gate 213 can be avoided, reducing the wear and collision situation.

[0030] In this embodiment, by using the protective plate 214, the friction between the two gates during the opening and closing process is prevented, and the damage caused by collision is reduced, thus reducing the maintenance frequency and cost, avoiding the impact between the gates, and reducing the possible safety risks.

One end of the square box groove 219 is connected and fixed with a first hydraulic cylinder 216 and a second hydraulic cylinder 217 by screws. The first hydraulic cylinder 216 and the second hydraulic cylinder 217 are equipped with push rods 224. One end of the push rod 224 is connected and fixed with a first filter plate 220 and a second filter plate 221 by bolts. The first filter plate 220 can block large epoxy resin raw material particles, while the disinfection particles will enter the second filter plate 221, and then enter the internal leakage hole 215 of the feed box 201 from the second filter plate 221, and finally be poured into the production preparation box 101. One end of the first filter plate 220 and the second filter plate 221 is connected and fixed with a moving guide post 223 by bolts. The moving guide post 223 is installed inside a sleeve column 218. The sleeve column 218 is connected through penetration on both side ends of the square box groove 219. During actual use, when the epoxy resin raw material particles are poured into the inside of the feed box 201, the first hydraulic cylinder 216 and the second hydraulic cylinder 217 are driven to move the push rod 224 to move back and forth, further driving the first filter plate 220 and the second filter plate 221 to move. The first filter plate 220 can block large epoxy resin raw material particles, while the disinfection particles will enter the second filter plate 221, and then enter the internal leakage hole 215 of the feed box 201 from the second filter plate 221, and finally be poured into the production preparation box 101. Then, through the movement of the moving guide post 223 inside the sleeve column 218, the movement stability of the first filter plate 220 and the second filter plate 221 can be maintained.

Through the movement of the moving guide post 223 inside the sleeve column 218, the movement stability of the first filter plate 220 and the second filter plate 221 can be maintained.

[0036] Fifth Embodiment:

When the lifting guide column 206 is moved by driving the lifting cylinder 205, and when the lifting guide column 206 moves backward, and the first gate 212 and the second gate 213 rotate through the first semi-circular gear 210 and the second semi-circular gear 211, then the first gate 212 and the second gate 213 are opened. When the first semi-circular gear 210 and the second semi-circular gear 211 are adjusted to rotate, the opening angle of the first gate 212 and the second gate 213 can be adjusted, and the amount of epoxy resin raw material particles poured into the interior of the production preparation box 101 can be controlled to be too much or too little, reducing problems such as too much epoxy resin raw material particles being poured into the production preparation box 101. By driving the first hydraulic cylinder 216 and the second hydraulic cylinder 217 to move the push rod 224 back and forth, the first filter plate 220 and the second filter plate 221 are further driven to move. The first filter plate 220 can block large epoxy resin raw material particles, while the disinfection particles will enter the second filter plate 221, and then enter the leakage holes 215 inside the feed box 201 from the second filter plate 221, and finally be poured into the interior of the production preparation box 101. After that, the moving guide column 223 moves inside the sleeve column 218.
