[0050] The graphite boat heat pressing feeding equipment is used for feeding powdery graphene into a mold 16 of a heat pressing equipment 1, and comprises a hopper 2 for storing powdery graphene and mounted on a support 201, the support 201 being formed by welding a metal frame, a lower end of the hopper 2 being formed with a lower discharging frame 22, an upper portion of the lower discharging frame 22 being in communication with an inside of the hopper 2 to form a discharging channel, the lower discharging frame 22 being provided with a through opening in a horizontal direction for feeding powdery graphene, and a guide groove 221 being formed at a bottom of the lower discharging frame 22 and in sliding fit with a material supporting plate 4; a standby material frame 3 being slid on the support plate 23 in a horizontal opening direction of the lower discharging frame 22, a positioning plate 231 being fixed at one end of the support plate 23 close to the heat pressing equipment 1, the positioning plate 231 being in contact with a side surface of a sliding seat 14 in a cooperation process of the feeding device and the heat pressing equipment 1, the standby material frame 3 being formed with a powdery graphene channel in a vertical direction, a top of the standby material frame 3 being in communication with the hopper 2 for feeding powdery graphene into the standby material frame 3, and a bottom of the standby material frame 3 being in communication with the mold 16 for feeding powdery graphene into the mold 16; an adjusting column 5 being in sliding fit through the standby material frame 3 for changing a loading capacity, the inside capacity of the standby material frame 3 being adjusted according to a required mass of powdery graphene corresponding to the mold 16 after the mold 16 is replaced, and flexibility and adaptability of use being significantly improved; a scraper 6 being horizontally slid in the standby material frame 3 and used for leveling powdery graphene in the mold 16, the scraper 6 ensuring that the powdery graphene can be evenly spread on the mold 16 and ensuring product quality of a graphite boat; and a driving mechanism 7 being mounted between the support 201 and the standby material frame 3 and driving the standby material frame 3 to reciprocally slide between the lower discharging frame 22 and the mold 16.

[0051] Specifically, in order to prevent powdery graphene in the standby material frame 3 from being raised when the standby material frame 3 is moved from a side of the lower discharging frame 22 and transported, a cover plate 24 is fixed at an upper end of an outwardly extending side of the hopper 2 close to the support plate 23, a sliding cover plate 241 is arranged on the cover plate 24, and the cover plate 24 and the cover plate 241 shield an upper end opening of the standby material frame 3 during transportation of the standby material frame 3 to the mold 16, so that dust raising during feeding is effectively inhibited, and a sliding groove and a sliding groove structure are arranged between the cover plate 24 and the cover plate 241 in the embodiment to ensure horizontal stable sliding of the cover plate 241 on the cover plate 24.

[0052] Further, in order to automatically cooperate sliding of the cover plate 241 with sliding of the standby material frame 3, an upper abutting plate 2411 is fixed at one side of the cover plate 241 downward in one direction and partially coincides with the standby material frame 3 in height, the upper abutting plate 2411 abuts against the standby material frame 3 when the standby material frame 3 moves toward the cover plate 241, that is, a state shown in FIG. 6, and the standby material frame 3 continues to slide to drive the cover plate 241 to slide out of the cover plate 24 and shield the upper end of the standby material frame 3, that is, a state shown in FIG. 7. Figure 5 Further, in order to automatically cooperate sliding of the cover plate 241 with sliding of the standby material frame 3, an upper abutting plate 2411 is fixed at one side of the cover plate 241 downward in one direction and partially coincides with the standby material frame 3 in height, the upper abutting plate 2411 abuts against the standby material frame 3 when the standby material frame 3 moves toward the cover plate 241, that is, a state shown in FIG. 6, and the standby material frame 3 continues to slide to drive the cover plate 241 to slide out of the cover plate 24 and shield the upper end of the standby material frame 3, that is, a state shown in FIG. 7. Figure 6The other direction, the cover plate 241 both ends are fixed with guide rod 2412 and sliding connection on the outside of the lower frame 22, the guide rod 2412 outside the sleeve with fixed between the cover plate 241 and the lower frame 22 spring 2413, when the material preparation frame 3 loading is completed, the material preparation frame 3 will be reset under the action of the drive mechanism 7 back into the lower frame 22, in the process, the cover plate 241 will be reset to coincide on the cover plate 24 under the action of the spring 2413, that is, the cover plate 241 is in the state shown in the figure. Figure 1 The other direction, the cover plate 241 both ends are fixed with guide rod 2412 and sliding connection on the outside of the lower frame 22, the guide rod 2412 outside the sleeve with fixed between the cover plate 241 and the lower frame 22 spring 2413, when the material preparation frame 3 loading is completed, the material preparation frame 3 will be reset under the action of the drive mechanism 7 back into the lower frame 22, in the process, the cover plate 241 will be reset to coincide on the cover plate 24 under the action of the spring 2413, that is, the cover plate 241 is in the state shown in the figure.

[0053] Further, in order to prevent the powder graphene in the hopper 2 from leaking during the loading of the material preparation frame 3, the material preparation frame 3 is fixed with a blocking plate 31 away from the mold 16, and the upper end of the blocking plate 31 is flush with the upper end of the material preparation frame 3. When the material preparation frame 3 moves horizontally to the side for loading, the blocking plate 31 at this time will slide into the lower frame 22 and block the passage between the upper end of the lower frame 22 and the hopper 2, so that the powder graphene in the hopper 2 will not be discharged.

[0054] Specifically, in order to ensure that the material preparation frame 3 is fully connected between the lower frame 22 and the mold 16, the material supporting plate 4 is fixed with a lower stop plate 41 on one side, which can abut against the side of the mold 16 during loading, and the material supporting plate 4 is flush with the upper surface of the mold 16. In this embodiment, the lower stop plate 41 abuts against the mold 16 to achieve the positioning purpose of the material supporting plate 4, and at the same time, it can build a smooth plane for the powder graphene in the material preparation frame 3 to enter the mold 16.

[0055] Further, in order to enable the material supporting plate 4 to slide horizontally on the lower frame 22, the lower end of the support plate 23 is fixed with a first electric push rod 42, and the output end is fixed with the lower stop plate 41. The abutting or disengaging of the lower stop plate 41 and the side of the mold 16 is realized by the extension or retraction of the first electric push rod 42.

[0056] More specifically, when the loading equipment is ready for loading, the first electric push rod 42 is started first, which abuts the lower stop plate 41 against the side of the mold 16, and then the drive mechanism 7 is started to drive the material preparation frame 3 to perform the loading action. After loading is completed, the material preparation frame 3 is reset. Before the hot pressing equipment 1 is started, in order to avoid interference between the lower stop plate 41, the material supporting plate 4 and the rising of the sliding seat 14, the first electric push rod 42 retracts the lower stop plate 41 and the material supporting plate 4, providing a space for the lifting of the sliding seat 14.

[0057] Further, the outer side of the adjusting column 5 away from the material preparation frame 3 is provided with a connecting plate 51, the number of adjusting columns 5 can be adjusted according to actual needs, all the adjusting columns 5 are fixed on the connecting plate 51, the connecting plate 51 is located outside the material preparation frame 3, the connecting plate 51 is fixedly connected with a threaded sleeve 52, the side of the material preparation frame 3 is rotatably connected with a screw rod 53 which is screw connected with the threaded sleeve 52, one end of the screw rod 53 is provided with a knob, and the lower side of the blocking plate 31 is provided with a window 311 for the rotation of the knob.

[0058] In use, the screw rod 53 is rotated by rotating the wheel, and the length of the adjusting column 5 in the material preparation frame 3 is adjusted through the screw of the screw rod 53 and the threaded sleeve 52.

[0059] The actual capacity of the material preparation frame 3 is calculated as follows: the diameter of the adjusting column 5 is constant, the internal capacity of the material preparation frame 3 is constant, the length of the adjusting column 5 entering the inside of the connecting plate 51 is adjusted, the capacity proportion of the adjusting column 5 in the material preparation frame 3 is calculated, and then the total capacity of the material preparation frame 3 is reduced by the proportion of the adjusting column 5, so as to obtain the capacity of the loadable powdered graphene.

[0060] More specifically, the surface of the adjusting column 5 can be provided with a scale, and the length of the adjusting column 5 entering the material preparation frame 3 can be directly obtained by observing the scale.

[0061] Further, the scraper 6 is fixed with a connecting rod 61 penetrating through the material preparation frame 3, and the blocking plate 31 is fixed with a second electric push rod 62 having an output end connected with the other end of the connecting rod 61, and the second electric push rod 62 works after the driving mechanism 7 drives the material preparation frame 3 to completely move to the upper side of the mold 16, and the scraper 6 is in the reset state as shown in the figure and is located on the right side of the material preparation frame 3.

[0062] When the material preparation frame 3 completes the feeding in use, there will be partial powder accumulated on the right side of the mold 16 and the material preparation frame 3, at this time the second electric push rod 62 is started to push the accumulated powder to the other side of the mold 16, and after the scraper 6 moves to the left side of the material preparation frame 3, the powder on the mold 16 is flattened at this time, and then the second electric push rod 62 is reversely started to reset the scraper 6 to the right side of the material preparation frame 3, at this time the whole feeding work is completed, the driving mechanism 7 is reversely started to reset the material preparation frame 3 to the discharging frame 22, and the material bin 2 automatically feeds the material preparation frame 3.

[0063] Specifically, the driving mechanism 7 includes a C-shaped plate 71 fixed to the side of the material preparation frame 3 and the blocking plate 31 and extending to the side, a rack 72 fixed to the lower end of the C-shaped plate 71, a driving gear 74 rotatably arranged on the bottom of the support plate 23 and engaged with the rack 72, an electric motor 73 fixed on the support 201, a driving gear 74 fixed to the output end of the electric motor 73 and engaged with the driving gear 74, and in order to ensure the stable movement of the material preparation frame 3, the C-shaped plate 71, the rack 72 and the electric motor 73 are symmetrically arranged in two groups, the two electric motors 73 are fixed through a connecting rod, the driving gear 74 is engaged with one of the electric motors 73, and then the two electric motors 73 are synchronously driven to engage with the rack 72 under the action of the connecting rod.

[0064] Further, in order to facilitate the feeding in the material bin 2, a spiral feeder 8 is arranged at the rear end of the material bin 2, the spiral feeder 8 includes a hopper 81, a conveying auger 82 connected to the hopper 81, a discharging pipe 83 connected to the upper end of the conveying auger 82 and communicated with the feeding port 21 on the material bin 2, and the discharging pipe 83 is arranged in a downward inclination.

[0065] Specifically, the total control box 9 is installed on the support 201, and the total control box 9 is connected with and controls the first electric push rod 42, the second electric push rod 62, the motor 73 and the motor on the conveying auger 82;

[0066] More specifically, in single feeding, the working sequence is that the first electric push rod 42 extends to abut the lower abutting plate 41 against the side of the mold 16, the motor 73 is started to push the material preparation frame 3 to coincide with the upper end of the mold 16, the second electric push rod 62 extends to push the scraper 6 to flatten the powder and then resets, the motor 73 is reversely started to reset the material preparation frame 3 to the discharging frame 22, and the first electric push rod 42 is reversely started to retract the lower abutting plate 41.

[0067] It should be clear that the first electric push rod 42 and the second electric push rod 62 are driven to extend and retract by the motor + mechanical structure (screw / nut) inside; meanwhile, the electric push rod motor, the driving mechanism motor and the spiral feeder motor are determined to rotate in a direction by the pulse direction instruction of the controller 9, and then rotate under the action of the special motor driver. In this process, the encoder feeds the position and speed information to the driver in real time.

[0068] It can be understood that the present application can quickly determine the mass of the powdery graphene by setting the upper and lower opening material preparation frame, and flexibly adjust the single hot pressing powder amount by the built-in adjusting column, and take into account the rapid quantitative feeding and process flexibility; the lower opening of the material preparation frame cooperates with the material supporting plate to automatically complete the feeding during sliding to the upper of the mold, and then the powder is flattened by the single reciprocating motion of the scraper, so as to realize the automatic feeding and flattening of the powdery graphene; the whole device adopts a closed design, and the feeding path from the stock bin to the material preparation frame is closed by the cover plate and the cover plate, so that the upper and lower openings of the material preparation frame are in a closed state during operation, thereby effectively suppressing dust and ensuring clean production.
