Vacuum vibration formation pressing machine producing quartzite

Abstract

The invention relates to a vacuum vibration formation pressing machine producing quartzite, which comprises a pressing machine and a feeding device, wherein the pressing machine comprises a machine base and a machine frame, the feeding device comprises a mould frame and a belt, and a vacuum vibration device is arranged on the machine frame. The vacuum vibration device is directly arranged in a mould cavity of the pressing machine and comprises a vacuum cover body connected with a vacuum pump, a pressing head provided with a vibration body and a power oil cylinder which can respectively enablethe vacuum cover body and the pressing head to rise and fall. Since the vacuum vibration device is adopted, the vacuum cover body and the pressing head descend to cover and close a mixed stone material after the mixed stone material which is put into a material frame is conveyed to the mould cavity by the belt, the tissue structure of the mixed stone material is mixed and firm and is evenly bondedby the operation of the vibration body and the vacuum pump, and water bubbles are discharged. Practice shows that the invention still can ensure that a product has better strength and hardness by thetechnical scheme under a condition that the resin content of the product is 7-9%, so that the production cost can be greatly lowered.

Description

technical field [0001] The invention relates to equipment for producing quartz stone, in particular to a vacuum vibration forming press for producing quartz stone. Background technique [0002] At present, the production of quartz stone mainly adopts two methods, one is manual production, this production method usually uses frame cloth, because the main raw material resin content of the cloth used is relatively random, usually the resin content is 28% Left and right, although the cost of the stone produced is low, its strength, hardness and other indicators often fail to meet the requirements for use. At the same time, manual production still has the disadvantages of low efficiency and high labor intensity. The second is mechanized automatic pouring production. Chinese patent CN1616201A discloses a "quartz stone production process and device". , The molding workshop includes two vacuum chambers, which can vibrate and squeeze the casting mold. The ingredients are fully stirr...
