With the vigorous development of automation and intelligent technology, industrialization is not only accelerating but also tends to be more intelligent. The market has therefore created an urgent need for advanced pressing equipment that can operate efficiently and accurately. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic dry powder conveying compression conveyor.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0005] An automated dry powder conveying and compression conveyor comprises: a hydraulic pressing device, a die pressing platform and an oil supply device, wherein the hydraulic pressing device can drive a pressing head to press the dry powder in a die pressing groove of the die pressing platform;

[0006] It is characterized by further comprising: a hydraulic lifting device and a film pressing table oil tank;

[0007] The die table is provided with a die table shell, a top pressing steel plate and at least one ejection device; the die table shell is provided with a top surface opening, the top pressing steel plate is slidably matched with the top surface opening of the die table shell, and the top pressing steel plate is provided with a top pressing steel plate through hole corresponding to each ejection device; the ejection device is composed of an ejection mold and a mounting base, the ejection mold is fixed in the die table inner cavity of the die table shell through the mounting base, and an oil clamping groove is provided on the side of the ejection mold; and each ejection mold is slidably matched with its corresponding top pressing steel plate through hole, so that the top pressing steel plate and the ejection mold close the top surface opening of the die table shell, and the inner cavity of the die table becomes a closed inner cavity;

[0008] The hydraulic lifting device can drive the top pressure steel plate to translate between the upper limit position and the lower limit position in the up-down direction, and, Figure 2 When the top pressing steel plate is translated to the upper limit position, the bottom surface of the top pressing steel plate is flush with the oil groove of the ejection mold, and the through hole of the top pressing steel plate and the top surface of the ejection mold form the film pressing groove; when the top pressing steel plate is translated to the lower limit position, the top surface of the top pressing steel plate is below the top surface of the ejection mold;

[0009] The circulating oil port of the film pressing table oil tank is connected to the inner cavity of the die pressing table; the oil supply device can supply oil to the hydraulic pressing device, the hydraulic lifting device and the film pressing table oil tank respectively.

[0010] Therefore, the automatic dry powder conveying and compression conveyor of the present invention can be used to press dry powder into dry powder pressed products, and in one of the links of pressing, that is, in the process of the top pressing steel plate being translated to the lower limit position, the oil in the oil slot is brought into the contact surface between the ejection mold and the through hole of the top pressing steel plate, so that the oil lubricates the top pressing steel plate through hole of the top pressing steel plate and the ejection mold; thereby, not only the wear of the top pressing steel plate and the ejection mold during operation is reduced, but also the adhesion between the dry powder pressed product and the through hole of the top pressing steel plate and the ejection mold can be reduced, so that the dry powder pressed product can be demolded more smoothly in step S5, thereby improving the demolding integrity and surface quality of the dry powder pressed product, solving the problem in the prior art that the edge of the dry powder pressed product is easily damaged during demolding, and ensuring the high efficiency and product quality of the dry powder pressed product production process.

[0011] Preferably: the automatic dry powder conveying compression conveyor further comprises a powder basket moving device and a control device;

[0012] The powder basket moving device can drive the powder basket to move in sequence between the loading position, the pressing position and the discharging position, and the bottom surface of the powder basket is provided with a bottom surface through hole corresponding to each through hole of the top pressing steel plate; and the loading position and the discharging position are respectively located on both sides of the outside of the die table, and when moving to the pressing position, each bottom surface through hole of the powder basket is located directly above the corresponding through hole of the top pressing steel plate;

[0013] The control device controls the operation of the automatic dry powder conveying compression conveyor in the following manner, including:

[0014] Step S1, controlling the oil supply device to supply oil, so that the oil flows into and fills the inner cavity of the die table through the die pressing table oil tank and the circulating oil port; wherein, when the top pressing steel plate descends, the excess oil in the inner cavity of the die pressing table flows back to the oil supply device through the circulating oil port and the die pressing table oil tank; and, using the oil supplied by the oil supply device, the hydraulic pressing device realizes hydraulic driving of the pressing head, and the hydraulic lifting device realizes hydraulic driving of the top pressing steel plate;

[0015] Step S2, see Figure 2 , control the powder basket moving device to drive the powder basket to move to the loading position, so as to load the dry powder into the powder basket; and reset, that is, control the hydraulic lifting device to drive the top pressing steel plate to move to the upper limit position, so that the through hole of the top pressing steel plate and the top surface of the ejection mold form the die pressing groove, and the oil in the inner cavity of the die pressing table flows into the oil clamping groove of the ejection mold;

[0016] Step S3, see Figure 3 , control the powder basket moving device to drive the powder basket to move from the loading position to the pressing position, so that the dry powder in the powder basket falls into the corresponding film pressing groove through the bottom through hole; then control the powder basket moving device to drive the powder basket to move from the pressing position back to the loading position to bring back the excess dry powder;

[0017] Step S4, see Figure 3 , controlling the hydraulic pressing device to drive the pressing head to press the dry powder in the corresponding film pressing groove to produce a dry powder pressed product;

[0018] Step S5, see Figure 4 , first control the hydraulic pressing device to drive the pressure head to reset, and then control the hydraulic lifting device to drive the top pressing steel plate to move horizontally to the lower limit position, so that the ejection device can eject the dry powder pressed product upward from the through hole of the top pressing steel plate to achieve demoulding;

[0019] Moreover, in the process of the top pressing steel plate being translated to the lower limit position, the oil in the oil slot is brought into the contact surface between the ejection mold and the through hole of the top pressing steel plate, so that the oil lubricates the top pressing steel plate through hole of the top pressing steel plate and the ejection mold; thereby, not only the wear of the top pressing steel plate and the ejection mold during operation is reduced, but also the adhesion between the dry powder pressed product and the through hole of the top pressing steel plate and the ejection mold can be reduced, so that the dry powder pressed product can be demolded more smoothly in step S5, thereby improving the demolding integrity and surface quality of the dry powder pressed product, solving the problem in the prior art that the edge of the dry powder pressed product is easily damaged during demolding, and ensuring the high efficiency of the dry powder pressed product production process and the product quality.

[0020] Step S6, controlling the powder basket moving device to drive the powder basket to move from the loading position to the pressing position to the discharging position, so that the powder basket pushes the demoulding dry powder pressed product to the product discharge port, so that the dry powder pressed product is transferred to the next process flow, such as being sent to the kiln receiving platform to wait for firing;

[0021] Step S7, loop through steps S2 to S6.
