Description

Technical Field

[0001] The utility model relates to the technical field of machine-made stone slabs and quartz stone slabs, and more specifically, it refers to a new type of plate pressing and forming machine. Background Art

[0002] At present, the inorganic stone slabs and quartz stone slab presses adopt a structure with two rows of vibrators. In the low-frequency working state of the vibrators, the exciting force provided by the vibrators is not enough to overcome the gravity and atmospheric pressure, and the pressing head cannot vibrate up and down as a whole. In the actual state, a certain position between the two rows of vibrators on the inorganic stone slab and quartz stone slab is used as a fulcrum, and the two rows of vibrators vibrate in different directions respectively, with the fulcrum as the center, causing the pressing head to vibrate like a seesaw. This vibration state will cause uneven distribution of resin and quartz sand near the fulcrum of the inorganic stone slab and quartz stone slab, showing an uncompacted state. In severe cases, color difference will occur, or the whole inorganic stone slab and quartz stone slab will crack along this position after curing. In addition, in the current technology, the inorganic stone press and quartz stone press directly contact the material with the pressing head, and the effects of vibration and downward pressure need to be improved.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

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

[0023] As Figures 1 to 6 shown, a new type of sheet pressing and forming machine provided by the present utility model includes a pressing head unit 10, a belt conveyor 20 and a base 30. The base 30 is arranged below the belt of the belt conveyor 20. The pressing head unit 10 is vertically installed above the belt of the belt conveyor 20 and faces the base 30. An equalizing pressure application unit 40 is arranged at the bottom end (the end facing the belt of the belt conveyor) of the pressing head unit 10. The equalizing pressure application unit 40 includes an intermediate plate 41 movably installed on the pressing head unit 10, an upper ball assembly 42 movably arranged above the intermediate plate 31, and a lower ball assembly 43 movably arranged below the intermediate plate 41. When the pressing head unit 10 generates a vibration force and presses down, the intermediate plate 41 is evenly pressed down through the upper ball assembly 42, and the lower ball assembly 42 is pressed down through the intermediate plate 41, so that the lower ball assembly 42 can apply pressure to the plate surface belt B above the mold tray, and the lower ball assembly 42 can evenly apply pressure to the material in the mold tray, increasing the compaction effect.

[0024] In this embodiment, the upper ball assembly 42, the intermediate plate 41 and the lower ball assembly 43 are installed at the bottom end of the pressing head unit 10 through guide posts 44 around them, so that the upper ball assembly 42, the intermediate plate 41 and the lower ball assembly 43 can all move towards the pressing head unit 10 to ensure that the lower ball assembly 43 can evenly apply pressure to the plate surface belt B.

[0025] In this embodiment, both the upper ball assembly 42 and the lower ball assembly 43 include a number of equally spaced balls 421 (431) and a cage 422 (432) for movably clamping each ball 421.

[0026] The indenter unit 10 includes a surrounding frame 13, an indenter 11 that is liftably disposed in the middle of the surrounding frame 13, and a plurality of vibration motors 12 mounted on the upper surface of the indenter 11. The vibration motors 12 in the length direction of the indenter 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 indenter 11 rotate synchronously. The vibration motors 12 on the upper and lower sides of the width direction ( Figure 1 of the indenter 101) are arranged side by side and the distance between every two adjacent vibration motors 12 is equal. The number of vibration motors 12 in the width direction of the indenter 11 is at least four. The rotation directions of two adjacent vibration motors 21 in the width direction of the indenter 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 cancel each other out or reduce the generated lateral force to the lowest level.

[0027] It is worth mentioning that a plurality of mechanical pressing devices are provided between the surrounding frame 13 and the base 30.

[0028] 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. To distinguish it from other hydraulic cylinders, the mechanical pressing device in this article is the first hydraulic cylinder 50.

[0029] A second hydraulic cylinder 60 for lifting the height of the indenter 11 is provided between the indenter 11 and the surrounding frame 13.

[0030] In this embodiment, a plurality of third hydraulic cylinders 70 for pushing the intermediate plate 41 to move are provided around the surrounding frame 13.

[0031] It is worth mentioning that in this embodiment, a vacuum pumping device (not shown in the figure) is installed and connected to the indenter 11 or the surrounding frame. Through the vacuum pumping device, the inside of the surrounding frame can be evacuated to a vacuum state, so that the indenter presses downward toward the base.

[0032] In this embodiment, the balanced pressure application unit relies on the first hydraulic cylinders and the third hydraulic cylinders around the surrounding frame 13 to reciprocate in multiple directions, that is, the hydraulic cylinders provide a downward pressure to press the entire indenter unit toward the base direction, or the third hydraulic cylinders provide a lateral driving force. The upper ball assembly 42 and the lower ball assembly 43 of the balanced pressure application unit can achieve the effect of reciprocating in multiple directions. The multiple directions are the width direction, the length direction or the diagonal direction on the surface of the base.

[0033] As Figure 2 shown, the usage method of the present utility model includes the following steps:

[0034] Step 1: Transport the mold tray loaded with materials to the lower part of the surrounding frame 13 through a belt conveyor;

[0035] Step 2: Press the surrounding frame downward toward the base through a mechanical pressing device to form a sealed space inside the surrounding frame.

[0036] Step 3: Evacuate the inside of the surrounding frame 13 through a vacuum pumping device to cause the pressing head to press downward toward the base;

[0037] Step 4: Vibrationally press the mold tray through the vibration motor installed on the pressing head;

[0038] Step 5: Press the materials in the mold tray back and forth through the balanced pressure application unit.

[0039] The balanced pressure application unit in the above Step 5 provides driving force through a third hydraulic press to achieve the effect of reciprocating motion.

[0040] What the present utility model aims to achieve is that the pressing head unit of the present utility model can evenly apply pressure to the intermediate plate through the upper ball assembly of the balanced pressure application unit, and through the intermediate plate, while ensuring pressure is applied to the lower ball assembly, the effect of rolling and pressing the belt on the plate back and forth can be achieved, that is, several balls of the lower ball assembly roll and press the belt on the plate back and forth to improve the material compaction effect.

[0041] The above are only embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. All equivalent structural or equivalent process transformations made using the content of the utility model's description and drawings, or directly or indirectly applied in other related technical fields, are similarly included within the patent protection scope of the utility model.
