Description

Technical Field

[0001] The utility model belongs to the technical field of external presses, and particularly relates to a new type of external press. Background Art

[0002] The external press is used for processing in an automatic production line for quartz stone pressing. The structure of this type of external press is simpler than that of traditional presses, the production cost is reduced, and the assembly accuracy is relatively reduced. At the same time, the external press avoids the transmission of the vibration force of the vibrating machine through the guide columns to the vibrating plate and the vacuum cover, which damages the internal structures of both, reduces the service life. The new structure of the vibrating plate and the vacuum cover are connected to the sealing leather, the vibration force transmission is small, the internal damage is reduced, and the maintenance rate is reduced. The internal sealed cavity is small, the time to form a vacuum is reduced, and the production efficiency is improved. 56 composite springs are used between the foundation and the base. When the vibrating machine vibrates, the vibration force transmitted to the base is reduced by the springs and cannot act on the ground. The existing external presses still have the following defects: (1) When the existing new type of external press is used for quartz stone pressing and processing, the quartz stone is placed on the base, a vacuum cavity is formed by covering it with a vacuum cover, and then the pressing and processing are carried out through the vibrating plate assembly. However, during the processing, when a vacuum cavity is generated by the cooperation of the vacuum cover and the vacuum control system, sundries in the cavity are easily sucked into the vacuum device system under the suction force, resulting in blockage and damage problems in the vacuum device system. For this reason, we propose a new type of external press. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a new type of external press to solve the problem that sundries easily enter the vacuum system when the new type of external press forms a vacuum cavity, resulting in blockage and damage of the vacuum system as mentioned in the above background art.

The vacuum suction nozzle is connected with the vacuum control mechanism through a pipeline. A filter screen plate is installed inside the vacuum suction nozzle. An installation frame is arranged on one side of the filter screen plate. A rotating column is inlaid on the installation frame through rotation. One end of the rotating column is connected with a turbine assembly, and the other end of the rotating column is connected with a brush board.

[0005] Preferably, a waste discharge cylinder is fixedly inlaid on the bottom surface of the vacuum suction nozzle, and a plug column is connected to the port of the waste discharge cylinder through a thread.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] (1) Through the designed mounting frame, turbine assembly, rotating column, brush plate and filter screen plate, a suction force is generated by the vacuum control mechanism. The gas in the vacuum chamber between the vacuum hood and the base is sucked out through the vacuum nozzle. During the suction process, the sundries in the vacuum chamber are filtered and blocked by the filter screen plate to prevent the sundries from entering the vacuum control mechanism of the utility model and causing blockage and damage. At the same time, the airflow generated by the suction force acts on the turbine assembly to drive the brush plate to rotate, and the brush plate timely clears the sundries intercepted on the surface of the filter screen plate to prevent the filter screen plate from being blocked, making the sundries filtration of the utility model stable and reliable. Through the designed waste discharge cylinder and plug column, the plug column is removed from the waste discharge cylinder to facilitate the discharge of the sundries cleaned from the vacuum nozzle. Through the designed sealing ring, the sealing at the plugging position of the plug column is sealed. Through the designed slideway, the sundries cleared from the filter screen plate by the brush plate are guided and slid under the action of the slideway, so that the sundries enter the waste discharge cylinder for convenient discharge and treatment later.

During the suction process, the sundries in the vacuum chamber are filtered and blocked by the filter screen board 16 to prevent the sundries from entering the vacuum control mechanism 7 of the present invention and causing blockage and damage. At the same time, the airflow generated by the suction acts on the turbine assembly 12 to drive the brush board 15 to rotate, and the brush board 15 timely clears the sundries intercepted on the surface of the filter screen board 16 to prevent the filter screen board 16 from being blocked, making the sundry filtration of the present invention stable and reliable.

[0021] In this embodiment, preferably, a waste discharge cylinder 9 is fixedly embedded on the bottom surface of the vacuum suction nozzle 8, and a plug 10 is threadedly connected to the port of the waste discharge cylinder 9. Through the designed waste discharge cylinder 9 and plug 10, the plug 10 is removed from the waste discharge cylinder 9 to facilitate the discharge of the debris cleaned from the vacuum suction nozzle 8. A sealing ring 11 is arranged between the plug 10 and the waste discharge cylinder 9. Through the designed sealing ring 11, the sealing of the plugging part of the plug 10 is achieved. The sealing ring 11 is sleeved on the outer wall of the plug 10. A slideway 17 is arranged at the port of the waste discharge cylinder 9. Through the designed slideway 17, the debris cleaned from the filter screen plate 16 by the brush plate 15 is guided to slide under the action of the slideway 17, so that the debris enters the waste discharge cylinder 9 for timely discharge and treatment later, and the slideway 17 is fixed on the surface of the filter screen plate 16.

[0022] In this embodiment, preferably, a ball groove is formed on the surface of the rotating column 18, and a ball 13 is embedded in the ball groove.

[0023] Working principle and usage process of the utility model: During the operation of the utility model, the hydraulic cylinder support assembly works to raise the vacuum hood 3, and the lifting hydraulic cylinder works to raise the vibrating plate assembly 4. Then, the template with raw materials is transported to the center position of the base 2. Subsequently, the vacuum hood 3 and the vibrating plate assembly 4 descend simultaneously. The vacuum hood 3 descends until it contacts the upper surface of the base 2, and there is a layer of silica gel between them. After the vacuum hood 3 is pressed tightly, there are no gaps at the four sides of the bottom surface. The vibrating plate assembly 4 descends to a certain height and stops, contacting the upper surface of the raw materials. Since there is a sealing skin at the four sides of the upper surface between the vibrating plate assembly 4 and the vacuum hood 3, connecting the two and pressing the sealing skin tightly, a sealed vacuum chamber is formed between the vacuum hood 3 and the vibrating plate assembly 4. The vacuum control mechanism 7 is activated to extract the air in the sealed vacuum chamber to form an internal vacuum. The vibration motor on the vibrating plate assembly 4 is started to drive the vibrating plate to shake, continuously squeezing the raw materials to extract the air and moisture between the raw materials, making the combination of the raw materials more compact. After squeezing for a period of time, the vibration stops, and the internal vacuum is broken. The vibrating plate assembly 4 and the vacuum hood 3 rise, and the raw materials are pushed out of the external press of the utility model. During the process of forming a vacuum chamber by the suction effect of the vacuum control mechanism 7 of the utility model, the gas in the vacuum chamber between the vacuum hood 3 and the base 2 is sucked out through the vacuum suction nozzle 8. During the suction process, the sundries in the vacuum chamber are filtered and blocked by the filter mesh plate 16 to prevent them from entering the vacuum control mechanism 7 of the utility model and causing blockage and damage. At the same time, the airflow generated by the suction acts on the turbine assembly 12 to drive the brush plate 15 to rotate, and the brush plate 15 timely clears the sundries intercepted on the surface of the filter mesh plate 16 to prevent the filter mesh plate 16 from being blocked, making the sundries filtration of the utility model stable and reliable.
