Description

Technical Field

[0001] This invention relates to stone processing equipment, specifically to an artificial stone pressing machine and method. Background Technology

[0002] Currently, artificial stone manufacturing generally employs two methods: pressing raw blocks and pressing slabs. Pressing slabs requires a pressing machine. Traditional pressing machines use sealing strips or air-sealed strips to seal the pressure head and outer frame. During the pressing process, these sealing strips are prone to wear due to vibration and leaks. After vacuuming, the connection between the pressure head, the pressing material, and the base becomes rigid, resulting in inefficient and uneven transmission of vibration force during the pressing process. These problems significantly impact the pressing efficiency and quality of the pressing machine. Summary of the Invention

[0003] In order to solve at least one of the technical problems existing in the background art, the present invention provides an artificial stone pressing machine and method, which has uniform and efficient vibration force transmission and good sealing performance.

[0004] This invention is achieved through the following technical solution:

[0005] In a first aspect, the present invention provides an artificial stone pressing machine, comprising a base, a conveying component, a sealing frame, a pressing head, a lifting device, and an annular sealing tape; wherein...

[0006] The conveying component is installed in the base; the pressure head is located above the conveying component and moves up and down by the drive of the lifting device; the sealing frame is set around the pressure head; the annular sealing tape is connected and installed between the sealing frame and the pressure head;

[0007] A sealing strip is provided at the bottom of the sealing outer frame;

[0008] An outer frame hook is also installed on the pressure head to drive the sealing outer frame to rise and fall together with the pressure head.

[0009] Furthermore, both the inner and outer rings of the annular sealing tape are provided with sealing tape pressure plates, which are used to connect to the pressure head and the sealing frame, respectively.

[0010] Furthermore, an elastic body is provided between the base and the base support surface.

[0011] Furthermore, the artificial stone pressing machine also includes a vacuum tube, which is connected to the sealing outer frame.

[0012] Furthermore, the artificial stone pressing machine also includes a pressing head pushing component, which includes a hydraulic cylinder bracket and a pushing hydraulic cylinder. The hydraulic cylinder bracket is mounted on the base, and the pushing hydraulic cylinder is mounted on the hydraulic cylinder bracket and positioned above the pressing head.

[0013] Furthermore, a vibration motor is installed on the upper end face of the pressure head, and the eccentric wheel of the vibration motor rotates to drive the pressure head to vibrate; a gravity hammer component is set above the pressure head, and the gravity hammer component jumps freely to hammer the pressure head during the vibration of the pressure head.

[0014] Furthermore, the gravity hammer component includes a gravity hammer bracket and a gravity hammer plate, with the gravity hammer bracket positioned above the pressure head and the gravity hammer plate placed on the gravity hammer bracket.

[0015] Furthermore, the lifting device is a lifting cylinder, and the pressure head is mounted on the lifting cylinder via a pressure head bracket.

[0016] Furthermore, an outer frame limiting seat is also provided on the base, with a gap between the outer frame limiting seat and the sealing outer frame to restrict the left-right and front-back translational movement of the sealing outer frame, so that the sealing outer frame can only move up and down.

[0017] Secondly, the present invention provides a method for pressing artificial stone, the method being based on the aforementioned pressing machine, the method comprising:

[0018] After the artificial stone material is mixed, it is loaded onto a pressing mold and placed at the feed inlet of the pressing machine.

[0019] The lifting cylinder rises, causing the pressure head to rise. After rising to a set distance, it drives the outer frame to rise via the outer frame hook. When the lifting cylinder extends to its maximum stroke, the outer frame and pressure head are separated from the conveyor belt by a certain height. The pressure plate mold is conveyed into the inner part of the outer frame via the conveyor belt, and the outer frame can surround the entire pressure plate mold and material. The lifting cylinder descends, and the outer frame first contacts the base and the conveyor belt. The sealing strip at the bottom of the outer frame ensures that there are no gaps between the outer frame and the base and belt, achieving a sealed state. The lifting cylinder continues to descend, causing the bottom of the pressure head to reach the top surface of the pressure plate material and move away by a certain distance.

[0020] Next, the vacuum system is activated to extract air between the sealing frame and the pressure head, as well as inside the material, through the vacuum tube. Once the set vacuum level is reached, the vacuum system continues to operate.

[0021] The lifting cylinder begins to descend until it reaches the lowest position and stops moving. At this point, the piston rod of the lifting cylinder is a certain distance away from the pressure head support. Even if the pressure head presses down on the base, the pressure head support will not touch the lifting cylinder.

[0022] Then the vibration motor is started, which makes the pressure head vibrate and extrude the die material. Combined with the vacuum negative pressure, the pressure head presses the material to the preset hardness and flatness. During the vibration of the pressure head, the gravity hammer plate hammers the pressure head as the pressure head vibrates. There is a gap between the pressure head and the sealing frame. The pressure head moves a certain distance in the horizontal direction. During the vibration process, the pressure head can not only move up and down, but also move left and right and back and forth.

[0023] If the pressure head deviates in height or the pressure head vibration force is insufficient during the pressing process of the mold material, the hydraulic cylinder extends to assist the pressure head in pressing the mold material, so as to ensure the thickness and flatness of the pressed part.

[0024] After the pressing head operates for a certain period of time, the material in the pressing mold reaches the preset shape and hardness. The vibration motor and vacuum system are then shut off, and the lifting cylinder rises. After rising a certain distance, the outer frame hook drives the sealing frame to rise. When the lifting cylinder extends its maximum stroke, the sealing frame and the pressing head are a certain height away from the base conveyor belt. The conveyor belt transports the pressing mold and material to the outside of the sealing frame, thus completing one pressing operation.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. Compared with the traditional method of installing a sealing strip between the inner side of the sealing frame and the outer side of the pressure head in a traditional pressure plate machine, the sealing between the sealing frame and the pressure head in this invention adopts an annular sealing tape, which solves the problems of air leakage during vibration and easy damage to the sealing strip, achieving complete air leakage. In addition, the good toughness of the sealing tape makes the sealing effect better and the service life longer.

[0027] 2. Traditional press machines have a sealing strip between the press head and the sealing frame, which restricts the movement of the press head during vibration. This invention uses an annular sealing tape, which allows the press head to move a certain distance from the sealing frame. During vibration, the press head can not only move up and down, but also left and right, and forward and backward, making the press head vibrate more freely. The pressed plates are more uniform and dense, thus improving the quality of the press.

[0028] 3. The present invention provides a gravity hammer component above the pressure head. During the vibration of the pressure head, the gravity hammer component jumps freely and hammers the pressure head, thereby increasing the density of the pressed part.

[0029] 4. An elastic body is placed between the pressing machine and the ground foundation of this invention. During the pressing process, the vibration of the base drives the mold to vibrate, which causes the bottom surface of the raw material in the mold to vibrate as well. By setting the elastic body, the vibration of the base can be reduced, so that the pressed plate is more uniform and dense, thus improving the pressing quality. Attached Figure Description

Detailed Implementation

[0034] Example:

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a signal connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The technical solution of this invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] See Figure 1-3 As shown, the artificial stone pressing machine provided in this embodiment mainly includes a base 01, a conveying component, a sealing frame 03, a pressing head 05, a lifting device, and an annular sealing tape 06.

[0037] In this embodiment, the conveying component uses a conveyor belt 02, which is installed in the middle of the base 01 to convey the mold 17. In other embodiments, the conveying component can also use other methods besides the conveyor belt 02, as long as it can convey the mold 17. The lifting device uses a lifting cylinder 04, which is installed on the base 01 and located on both sides of the conveyor belt 02. The pressing head 05 is installed on the lifting cylinder 04 through the pressing head lug 10 and is located directly above the conveyor belt 02. The pressing head 05 can move up and down on the conveyor belt 02 via the lifting cylinder 04 to press the stone material in the mold 17. An outer frame hook 09 is also installed on the pressing head 05 to drive the sealing outer frame 03 to rise and fall together with the pressing head 05. In other embodiments, the lifting device can also use other methods besides the lifting cylinder 04, as long as it can drive the pressing head to move up and down.

[0038] The sealing frame 03 is located around the pressure head 05, with a gap between them. This means that the pressure head 05 can move within the gap. When the pressure head 05 rises, it is lifted along with the sealing frame 03 via the outer frame hook 09. When the mold 17 reaches the processing position, it falls again with the pressure head 05, surrounding the entire mold 17. A sealing strip is installed at the bottom of the sealing frame 03. When the sealing frame 03 falls onto the conveyor belt 02, the surrounding air cannot enter the interior of the sealing frame 03 through the sealing strip. The vacuum tube 15 is connected to the sealing frame and is used to evacuate the sealed space inside the sealing frame 03.

[0039] An annular sealing tape 06 is provided between the pressure head 05 and the sealing outer frame 03, preventing air from entering the gap between the sealing outer frame 03 and the pressure head 05 through the annular sealing tape 06, or preventing air in the gap from flowing out through the annular sealing tape 06; this, combined with the vacuum tube 15, quickly extracts air from between the sealing outer frame 03 and the pressure head 05 and from inside the material. Compared with the traditional method of installing a sealing strip between the inner side of the sealing outer frame and the outer side of the pressure head in a press machine, the sealing between the sealing outer frame 03 and the pressure head 05 in this invention uses an annular sealing tape 06, which solves the problems of air leakage during vibration and easy damage to the sealing strip, achieving complete air leakage. In addition, the good toughness of the sealing tape makes the sealing effect better and the service life longer. Compared with traditional plate presses where a sealing strip is placed between the press head and the sealing frame, restricting the movement of the press head during vibration, this invention uses an annular sealing tape. The press head 05 can move a certain distance from the sealing frame 03. During vibration, the press head 05 can not only move up and down, but also left and right, and forward and backward, making the press head 05 vibrate more freely, and the pressed plate is more uniform and dense, thus improving the quality of the plate.

[0040] As a preferred embodiment, an elastic body is provided between the base 01 and the ground foundation. Since the base 01 vibrates during the pressing process, it causes the mold 17 to vibrate, which in turn causes the bottom surface of the mold material to vibrate. By providing an elastic body between the base 01 and the ground foundation, the vibration of the bottom surface of the mold material can be reduced, thereby making the pressed plate more uniform and dense, and improving the pressing quality.

[0041] As another preferred embodiment, a hydraulic cylinder bracket 12 is installed at each of the left and right ends of the base 01. The hydraulic cylinder bracket 12 is equipped with two pressing hydraulic cylinders 13, which are located above the pressing head. If the height difference of the pressing head 05 is significantly offset or the vibration force of the pressing head 05 is insufficient during the pressing process of the pressing head 05 pressing the material of the mold 17, the pressing cylinder 13 extends to assist the pressing head 05 in pressing the material of the mold 17, thereby ensuring the thickness and flatness of the pressed part.

[0042] In another preferred embodiment, an outer frame limiting seat 08 is provided on the base 01, with a gap between the outer frame limiting seat 08 and the sealing outer frame 03, to restrict the left-right and front-back translational movement of the sealing outer frame 03, so that the sealing outer frame 03 can only move up and down. By restricting the front-back and left-right movement of the sealing outer frame 03, the range of front-back and left-right movement of the pressure head 05 is also restricted accordingly, so that the pressure head will not run outside the mold 17 during vibration.

[0043] In one specific embodiment, both the inner and outer rings of the annular sealing tape 06 are provided with sealing tape pressure plates 07. The sealing tape pressure plate 07 on the inner ring is connected to the pressure head 05, and the sealing tape pressure plate 07 on the outer ring is connected to the sealing outer frame 03, so as to further prevent air from entering the gap between the sealing outer frame 03 and the pressure head 05 through the annular sealing tape 06 from the outside, or prevent the air in the gap from flowing out of the annular sealing tape 06.

[0044] Multiple vibration motors 12 are installed on the upper surface of the pressure head 05. During vibration, the vibration motors 12 drive the pressure head 05 to vibrate, causing the pressure head 05 to continuously compress the die material. In addition, a gravity hammer component is also provided above the pressure head 05. During the vibration of the pressure head, the gravity hammer component freely bounces and hammers the pressure head, thereby increasing the density of the pressed part. Specifically, the gravity hammer component includes a gravity hammer support 14 and a gravity hammer plate 15. The gravity hammer support 14 is positioned above the pressure head, and the gravity hammer plate 15 is placed on the gravity hammer support. During vibration, the gravity hammer plate 15 and the gravity hammer support 14 bounce up and down together, hammering the pressure head 05, thereby increasing the density of the pressed part.

[0045] Accordingly, this embodiment also provides a method for pressing artificial stone based on the above-mentioned pressing machine, which specifically includes the following steps:

[0046] After the artificial stone material is mixed, it is loaded onto a pressing mold 17 and placed at the feed inlet of the pressing machine.

[0047] The lifting cylinder 04 rises, causing the pressure head 05 to rise. After rising a certain distance, it drives the sealing outer frame 03 to rise via the outer frame hook 09. When the lifting cylinder 04 extends to its maximum stroke, the sealing outer frame 03 and the pressure head 05 are a certain height away from the conveyor belt 02. The pressure plate mold 17 is conveyed into the sealing outer frame 03 via the conveyor belt 02, and the sealing outer frame 03 can surround the entire pressure plate mold 17 and the material. The lifting cylinder 04 descends, and the sealing outer frame 03 first contacts the base 01 and the belt. The sealing strip at the bottom of the sealing outer frame 03 ensures that there are no gaps between the sealing outer frame 03 and the base 01 and the belt, achieving a sealed state. The lifting cylinder 04 continues to descend, causing the bottom of the pressure head 05 to reach the top surface of the pressure plate material and move away by a certain distance.

[0048] Next, the vacuum system is started, and the air between the sealing frame 03 and the pressure head 05 and inside the material is quickly extracted through the vacuum tube 16. After a certain vacuum degree is reached, the vacuum system continues to work.

[0049] The lifting cylinder 04 begins to descend until it reaches the lowest position and stops moving. At this time, the piston rod of the lifting cylinder 04 is a certain distance away from the pressure head support 10. Even if the pressure head 05 presses down on the base 01, the pressure head support 10 will not touch the lifting cylinder 04.

[0050] Then, the vibration motor 11 is started, causing the pressure head 05 to continuously vibrate and extrude the material of the die 17. Combined with the vacuum negative pressure, the pressure head 05 presses the material to the preset hardness and flatness. During the vibration of the pressure head 05, the gravity hammer plate 15 hammers the pressure head 05 along with the vibration of the pressure head 05. There is a gap between the pressure head 05 and the sealing frame 03, which can move a certain distance in the horizontal direction. During the vibration process, the pressure head 05 can not only move up and down, but also move left and right and back and forth, making the pressure head 05 vibrate more freely and the pressed plate more uniform and dense.

[0051] If the pressure head 05 experiences a significant height difference deviation or insufficient vibration force during the pressing process of the die 17, the pressing cylinder 13 extends to assist the pressure head 05 in pressing the material of the die 17, thereby ensuring the thickness and flatness of the pressed part.

[0052] After the pressing head operates for a certain period of time, the material in the pressing mold 17 reaches the preset shape and hardness. The vibration motor 11 and vacuum system are then turned off, and the lifting cylinder 04 rises. After rising a certain distance, it drives the sealing outer frame 03 to rise via the outer frame hook 09. When the lifting cylinder 04 extends to its maximum stroke, the sealing outer frame 03 and the pressing head 05 are separated from the base 01 conveyor belt by a certain height. The conveyor belt 02 transports the pressing mold 17 and the material to the outside of the sealing outer frame 03, thus completing one pressing action.

[0053] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
