Description

Technical Field

[0001] The invention relates to the technical field of machine stone slabs and quartz stone slabs, and more specifically to a novel plate pressing and forming machine. Background Art

[0002] The current inorganic stone slab and quartz slab presses use a two-row vibrator structure. When the vibrator is working at a low frequency, the exciting force provided by the vibrator is not enough to overcome gravity and atmospheric pressure, and the pressure head cannot vibrate up and down as a whole. The actual state is that a certain position between the two rows of vibrators on the inorganic stone slab and quartz slab is used as the fulcrum. The two rows of vibrators vibrate in different directions, with the fulcrum as the center, causing the pressure head to vibrate like a seesaw. This vibration state will cause the resin and quartz sand near the fulcrum of the inorganic stone slab and quartz slab to be unevenly distributed, presenting an uncompacted state. In severe cases, color difference will occur, or the entire inorganic stone slab and quartz slab will crack along this position after curing. In addition, the current inorganic stone press and quartz press have the pressure head in direct contact with the material, and the vibration and downward pressure effects need to be improved. Summary of the invention

[0003] The main purpose of the present invention is to provide a new type of plate pressing and forming machine, which can roll and press the plate surface belt above the mold back and forth through its balanced pressure unit to improve the compaction effect of the material.

[0004] The technical solution adopted by the present invention is: a new type of sheet metal pressing and forming machine, including a pressure head unit, a belt conveyor and a base, wherein the base is arranged below the belt of the belt conveyor, and the pressure head unit can be raised and lowered and installed above the belt of the belt conveyor and facing the base, and is characterized in that: a balanced pressure unit is arranged at the bottom end of the pressure head unit, and the balanced pressure unit includes an intermediate plate movably installed on the pressure head unit, an upper ball assembly movably arranged above the intermediate plate, and a lower ball assembly movably arranged below the intermediate plate.

[0005] The upper ball assembly, the middle plate and the lower ball assembly are mounted around the bottom end of the pressure head unit through guide columns.

[0006] The upper ball assembly and the lower ball assembly both include a plurality of balls distributed at equal distances and a retaining frame for movably clamping each of the balls.

[0007] The pressure head unit comprises a surrounding frame, a pressure head which can be lifted and lowered in the middle of the surrounding frame, and a plurality of vibration motors which are installed on the upper surface of the pressure head.

[0010] A plurality of first hydraulic cylinders are arranged between the surrounding frame and the base.

[0011] A second hydraulic cylinder for raising the height of the pressure head is arranged between the pressure head and the surrounding frame.

[0012] A plurality of third hydraulic cylinders for pushing the middle plate to move are arranged around the surrounding frame.

[0013] The method for using the novel sheet material pressing and forming machine comprises the following steps: Step 1: transport the mold tray containing the material to the bottom of the enclosure frame by a belt conveyor; Step 2: Use a mechanical pressing device to press the frame downward toward the base to form a closed space inside the frame.

[0020] In order to facilitate the understanding of the invention, the invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the invention belongs. The terms used in the specification of the invention herein are only for the purpose of describing specific embodiments and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] like Figures 1 to 6 As shown, a novel sheet material pressing and forming machine provided by the present invention comprises a pressing head unit 10, a belt conveyor 20 and a base 30, wherein the base 30 is arranged below the belt of the belt conveyor 20, the pressing head unit 10 can be lifted and installed above the belt of the belt conveyor 20 and facing the base 30, and a balanced pressure unit 40 is arranged at the bottom end of the pressing head unit 10 (the end facing the belt of the belt conveyor), and the balanced pressure unit 40 comprises a middle portion movably installed on the pressing head unit 10 Plate 41, an upper ball assembly 42 movably arranged above the middle plate 31, and a lower ball assembly 43 movably arranged below the middle plate 41. When the pressure head unit 10 generates vibration force and presses downward, the middle plate 41 is evenly pressed down by the upper ball assembly 42, and the lower ball assembly 42 is pressed down by the middle plate 41, so that the lower ball assembly 42 can apply pressure to the plate belt B above the mold tray, and the lower ball assembly 42 can evenly apply pressure to the material in the mold tray to increase the compaction effect.

[0024] In this embodiment, the upper ball assembly 42, the middle plate 41 and the lower ball assembly 43 are installed on the bottom end of the pressure head unit 10 through guide columns 44 so that the upper ball assembly 42, the middle plate 41 and the lower ball assembly 43 can all move toward the pressure head unit 10 to ensure that the lower ball assembly 43 can evenly apply pressure to the board belt B.

[0025] In this embodiment, the upper ball assembly 42 and the lower ball assembly 43 both include a plurality of balls 421 (431) distributed at equal distances and a retaining frame 422 (432) for movably clamping each ball 421.

[0026] The pressure head unit 10 includes a frame 13, a pressure head 11 which can be lifted and lowered in the middle of the frame 13, and a plurality of vibration motors 12 installed on the upper surface of the pressure head 11. The vibration motors 20 in the length direction of the pressure head 11 are arranged side by side and every two adjacent vibration motors 12 are connected in series through a coupling A, so that all the vibration motors 12 in the length direction of the pressure head 11 rotate synchronously. Figure 1 The vibration motors 12 on the upper and lower sides of the pressure head 11 are arranged side by side and the spacing between every two adjacent vibration motors 12 is equal. The number of the vibration motors 12 in the width direction of the pressure head 11 is at least four, and the rotation directions of the two adjacent vibration motors 21 in the width direction of the pressure head 11 are opposite, so that when the vibration motors 12 cannot operate synchronously, the lateral forces generated by the vibration motors 12 in the width direction can offset each other or minimize the generated lateral forces.

[0027] It is worth mentioning that a number of mechanical pressing devices are provided between the frame 13 and the base 30. The mechanical pressing device is a hydraulic cylinder, a screw lifting mechanism or an electric control push rod. In this embodiment, it is a hydraulic cylinder. In order to distinguish it from other hydraulic cylinders, the mechanical pressing device in this article is a first hydraulic cylinder 50.

[0028] A second hydraulic cylinder 60 for raising the height of the pressing head 11 is disposed between the pressing head 11 and the surrounding frame 13 .

[0029] In this embodiment, a plurality of third hydraulic cylinders 70 for pushing the middle plate 41 to move are disposed around the surrounding frame 13 .

[0030] It is worth mentioning that in this embodiment, the pressure head 11 or the surrounding frame is installed with a vacuum device (not shown in the figure), which can evacuate the interior of the surrounding frame to a vacuum state so that the pressure head is pressed downward toward the base.

[0031] In this embodiment, the balanced pressure unit reciprocates in multiple directions by means of the first hydraulic cylinder and the third hydraulic cylinder around the frame 13, that is, the hydraulic cylinder provides downward pressure to press the pressure head unit as a whole toward the base, or the third hydraulic cylinder provides lateral driving force, and the upper ball assembly 42 and the lower ball assembly 43 of the balanced pressure unit can achieve the effect of reciprocating in multiple directions. The multiple directions are the width direction, length direction or diagonal direction of the base surface.

[0032] like Figure 2 The method of using the present invention includes the following steps: Step 1: transport the mold tray containing the material to the bottom of the enclosure 13 by a belt conveyor; Step 2: Use a mechanical pressing device to press the frame downward toward the base to form a closed space inside the frame. Step 3, vacuuming the interior of the surrounding frame 13 by a vacuuming device, so that the pressing head is pressed downward toward the base; Step 4, vibrating and pressing the mold tray through a vibration motor installed on the pressure head; Step 5: The material in the mold tray is pressed back and forth by a balanced pressure unit.

[0033] The balanced pressure unit in step five provides a driving force through the third hydraulic press to achieve a reciprocating motion effect.

[0034] What the present invention aims to achieve is that the pressure head unit of the present invention can evenly apply pressure to the middle plate through the upper ball assembly of the balanced pressure unit, and through the middle plate, it can ensure that while applying pressure to the lower ball assembly, the plate belt can be pressed down by rolling back and forth, that is, the plate belt is rolled back and forth and pressed down by several balls of the lower ball assembly to improve the material compaction effect.
