[0043] Please also read Figure 1 and Figure 2 The energy-saving ceramic powder dry pressing molding equipment includes a supporting platform 1, multiple sliding seats 2, a sliding drive mechanism, multiple molding molds 3, a molding drive mechanism and a feeding mechanism 5, wherein the supporting platform 1 is provided with an annular slideway 101, multiple sliding seats 2 are slidably arranged on the slideway 101, the sliding drive mechanism is arranged on the supporting platform 1, the sliding drive mechanism is connected to the sliding seat 2, multiple molding molds 3 correspond to the sliding seat 2 one by one, the molding mold 3 is arranged on the top of the corresponding sliding seat 2, the molding drive mechanism is arranged on the supporting platform 1, and a molding block is provided at the power output end of the molding drive mechanism. The sliding drive mechanism can drive the sliding seat 2 to move along the slideway 101, so that different molding molds 3 are arranged below the molding block. The molding drive mechanism is used to drive the molding block to be pressed into the molding mold 3 below. The feeding mechanism 5 comprises a silo 501, a quantitative component 503 and a guide pipe 502. The silo 501 is arranged on one side of the support platform 1. The quantitative component 503 is rotatably arranged on one side of the discharge port of the silo 501. The quantitative component 503 is provided with two symmetrically arranged quantitative grooves 508. One of the quantitative grooves 508 is received below the discharge port, and one side wall of the quantitative groove 508 received below the discharge port is vertically arranged, and the other side wall is inclinedly arranged, so that the quantitative component 503 can rotate under the action of the gravity of the material and the quantitative grooves can be interchanged. One end of the guide pipe 502 is received on one side of the quantitative component 503, and the other end of the guide pipe 502 is arranged above one of the molding molds 3. The sliding drive mechanism can drive the sliding seat 2 to rotate along the slideway 101 so that different molding molds 3 are received below the guide pipe 502.

[0044] The energy-saving ceramic powder dry pressing molding equipment provided by the present embodiment has the following beneficial effects: compared with the prior art, the energy-saving ceramic powder dry pressing molding equipment provided by the present embodiment is provided with a rotating quantitative component 503, and two symmetrically arranged quantitative grooves 508 are provided on the quantitative component 503, wherein one quantitative groove 508 is received below the discharge port, and one side wall of the quantitative groove 508 received below the discharge port is vertically arranged, and the other side wall is inclined. When the material enters the quantitative groove 508, the gravity of the material will act on the inclined side wall of the quantitative groove 508. As the material accumulates, when the gravity of the material reaches the expected value, it will push the quantitative component 503 to rotate, so that the two quantitative grooves 508 exchange positions, and the material in the quantitative groove 508 that originally received the material enters the molding mold 3 through the material guide pipe 502 to complete the quantitative loading. Compared with the prior art, the scheme of the present invention does not require the use of external electric drive, is more energy-saving, clean and environmentally friendly, and has a simple structure and convenient maintenance, which greatly improves the working efficiency of dry pressing molding.

[0045] In this embodiment, the quantitative component 503 includes a quantitative shaft 504, two fixed plates 505, two first side plates 506 and two second side plates 507. The two fixed plates 505 are arranged at intervals, and the quantitative shaft 504 is rotatably arranged between the two fixed plates 505. The first side plate 506 and the second side plate 507 correspond to each other one by one. The two first side plates 506 are symmetrically arranged on the quantitative shaft 504. The corresponding first side plates 506, the second side plates 507 and the two fixed plates 505 enclose a quantitative groove 508. The first side plate 506 and the second side plate 507 both extend along the diameter of the quantitative shaft 504. The length of the first side plate 506 is greater than the length of the second side plate 507. In the initial state, The first side plate 506 is arranged vertically, and the second side plate 507 is arranged obliquely, a connecting plate 509 is provided between the fixed plates 505, and a limiting plate 510 is provided on the connecting plate 509, the limiting plate 510 is made of elastic material, and the distance from the top of the limiting plate 510 to the center of the quantitative shaft 504 is greater than the distance from the top of the second side plate 507 to the center of the quantitative shaft 504, and the distance from the top of the limiting plate 510 to the center of the quantitative shaft 504 is less than the distance from the top of the first side plate 506 to the center of the quantitative shaft 504. In the initial state, the lower first side plate 506 abuts against the limiting plate 510, and the limiting plate 510 can be deformed and reset due to the rotation of the quantitative shaft 504.

[0046] The setting of the limiting plate 510 ensures that only when the material in the quantitative slot 508 reaches a preset weight and the force acting on the second side plate 507 is greater than the force required for the deformation of the limiting plate 510, the limiting plate 510 deforms, and the gravity of the material can drive the quantitative shaft 504 to rotate, thereby achieving the purpose of quantitative feeding. In addition, it is worth noting that when the material in the quantitative slot 508 is completely discharged and the quantitative shaft 504 continues to rotate due to inertia, the limiting plate 510 can block the first side plate 506 to ensure that the quantitative slot 508 at the top is received below the discharge port.

[0047] Combination Figure 3 and Figure 4As shown, a driving cavity 511 is provided inside the first side plate 506, and mercury 512 is filled in the driving cavity 511, and the volume of the mercury 512 is equal to half of the volume of the driving cavity 511, and the mercury 512 can flow in the driving cavity 511 due to the rotation of the quantitative shaft 504. When the force required for the deformation of the limit plate 510 is small, that is, when the feed amount required is small, the force exerted on the second side plate 507 by the gravity of the material will not be too large, and it will be difficult to achieve a 180-degree rotation of the quantitative shaft 504 simply by relying on inertia. The drive chamber 511 and the mercury 512 are arranged such that when the first side plate 506 at the top rotates to below the horizontal line under the action of the gravity of the material, the mercury 512 in the drive chamber 511 moves to an end away from the center of the quantitative shaft 504. At this time, the other first side plate 506 is above the horizontal line, and the mercury 512 in its drive chamber 511 moves to an end close to the quantitative shaft 504. At this time, the mercury 512 in the drive chamber 511 of the first side plate 506 below the horizontal line drives the quantitative shaft 504 to rotate by gravity until it abuts against the limit plate 510.

[0048] like Figure 5 , a sealing plate 513 is provided on the quantitative shaft 504, and the sealing plate 513 can rotate with the rotation of the quantitative shaft 504. Two through holes 514 are provided on the sealing plate 513. The two through holes 514 are symmetrically arranged with the quantitative shaft 504 as the axis. The through holes 514 correspond to the quantitative slots 508 one by one. In the initial state, a certain amount of slots 508 are connected to the bottom of the discharge port, and the through holes 514 corresponding to the quantitative slots 508 are connected to the discharge port. When the two quantitative slots 508 are not connected to the bottom of the discharge port due to the rotation of the quantitative shaft 504, the sealing plate 513 blocks the discharge port. The setting of the sealing plate 513 makes it possible for the quantitative shaft 504 to rotate, and when the quantitative slots 508 are not connected to the bottom of the discharge port, the sealing plate 513 will block the discharge port to prevent the material from falling into the quantitative slots 508 and causing waste.

[0049] like Figure 1 and Figure 2 As shown, the top of the guide tube 502 is an arc-shaped port. When the quantitative shaft 504 rotates, the first side plate 506 abuts against the arc-shaped port of the guide tube 502. Each fixed plate 505 is provided with a fixed rod 515, and the other end of the fixed plate 505 is connected to the side wall of the silo 501. The setting of the arc-shaped port can not only facilitate the material to enter the guide tube 502, but also prevent the guide tube 502 and the first side plate 506 from interfering with each other.

[0050] like Figure 6 and Figure 7As shown, the support platform includes a support plate 102 and a support leg 103 at the bottom of the support plate 102. The support plate 102 is provided with an annular slideway 101. The slideway 101 divides the support plate 102 into a circular inner plate 104 and an annular outer plate 105. The inner wall of the outer plate 105 is provided with a first guide groove 106, and the outer wall of the inner plate 104 is provided with a second guide groove 107. The sliding seat 2 is inserted into the slideway 101, and the outer wall of the sliding seat 2 is provided with a first slide plate 201, and the inner wall of the sliding seat 2 is provided with a second slide plate 202. The first slide plate 201 is inserted into the first guide groove 106, and the second slide plate 202 is inserted into the second guide groove 107. The provision of the first guide groove 106, the second guide groove 107, the first slide plate 201 and the second slide plate 202 can facilitate the sliding of the sliding seat 2 along the slideway 101 on the one hand, and can also play an auxiliary supporting role for the inner plate 104 on the other hand.

[0051] In this embodiment, the sliding drive mechanism includes a stepper motor 4, an output shaft 401, a plurality of driving rods 402 and a pad 403. The stepper motor 4 is arranged at the bottom of the inner plate 104, and the output end is connected to the power output end of the stepper motor 4. The driving rods 402 correspond to the sliding seats 2 one by one. One end of the driving rod 402 is connected to the output shaft 401, and the other end of the driving rod 402 is connected to the corresponding sliding seat 2. The pad 403 is arranged on the ground, and a bearing 404 is arranged on the pad 403. The bottom end of the output shaft 401 is connected to the bearing 404. The arrangement of the stepper motor 4 and the driving rod 402 can facilitate driving the sliding seat 2 to rotate an angle each time, so that the material guide tube 502 can feed different molding molds 3.

[0052] Combination Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a slide groove 203 is provided on the top of the sliding seat 2, and a plurality of vibration plates 204 are provided on the relatively arranged side walls of the slide groove 203. A plurality of vibration grooves 301 are provided on the side walls of the molding mold 3. The vibration grooves 301 correspond to the vibration plates 204 one by one. The vibration plates 204 are made of elastic material. The vibration plates 204 can be deformed under the push of the sliding seat 2, and when the projection of the vibration plate 204 on the side wall of the slide groove 203 is covered by the projection of the vibration groove 301 on the side wall of the slide groove 203, the vibration plate 204 is reset and hits the side wall of the vibration groove 301.

[0053] In addition, a return spring 206 is provided at the bottom of the slide groove 203, and the top of the return spring 206 is connected to the bottom of the molding mold 3. When the return spring 206 is in a natural state, the bottom of the molding mold 3 is arranged above the vibration plate 204, and a guide groove 207 is provided on the side wall of the slide groove 203. A guide block 302 is provided on the side wall of the molding mold 3, and the guide block 302 is inserted into the guide groove 207.

[0054] like Figure 8 When the return spring 206 is in a natural state, the bottom plate of the molding die 3 is above the vibration plate 204. Fig. 9 As the forming block applies pressure to the forming mold 3, the forming mold 3 moves downward, pushing the vibration plate 204 downward. Fig.10 Until the molding die 3 moves down to the bottom of the slide groove 203 at the top of the sliding seat 2, the projection of the vibration plate 204 on the side wall of the slide groove 203 is covered by the projection of the vibration groove 301 on the side wall of the slide groove 203. At this time, the vibration plate 204 can be reset. Fig.11 As shown, the vibration plate 204 is reset and hits the top side wall of the vibration groove 301, so that the molding die 3 vibrates, and the bubbles between the materials in the molding die 3 are discharged, thereby improving the yield rate of the finished product. When the molding block no longer applies pressure to the molding die 3, the reset spring 206 drives the molding die 3 to reset.
