[0020] As a preferred solution of the present invention, air guiding patterns are opened at the bottom of the guiding pad.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this solution, the raw materials of artificial quartz stone plates are evenly distributed on the top of the transmission belt. The first motor is powered on and started. The raw materials of artificial quartz stone plates are moved between the vibrating plate and the vacuum pressing block. The second motor is powered on and started. The output end of the second motor drives the lead screw to rotate. The lead screw pushes the slider to reciprocate between the inner walls of the hollow frame through the sliding cooperation with the slider. At the same time, the sliding cooperation between the guide post and the infrared laser emitter guides one end of the guiding pad. Then the slider unfolds the guiding pad in the hollow frame by unidirectional pulling, so that the guiding pad is located between the vacuum pressing block and the transmission belt. The pattern on the lower side of the guiding pad fits the raw materials of the artificial quartz stone plate. At the same time, when the guiding pad moves, the servo motor is powered on and slightly starts to rotate the reel to slightly tighten the guiding pad. The two shrinkage cylinders are powered on and started. The two shrinkage cylinders press down the vacuum pressing block, so that the guiding pad under the vacuum pressing block fits the transmission belt and the vibrating plate. The negative pressure pump externally connected to the vacuum pressing block is powered on and started, so that the space between the vacuum pressing block, the vibrating plate and the transmission belt is in a negative pressure state. At the same time, the vibrating plate is powered on and started. The vibrating plate performs high-frequency vibration on the raw materials of the artificial quartz stone plates on the transmission belt, extrudes the air between the particles of the raw materials of the artificial quartz stone plates, and at the same time, the air guiding patterns on the lower side of the guiding pad guide the extruded air to both sides and are exhausted by negative pressure. By guiding and exhausting the gas between the particles of the raw materials of the artificial quartz stone plates, the small holes in the artificial quartz stone plates are reduced, and the structural strength of the artificial quartz stone plates is improved.

[0023] 2. In this solution, during the unfolding process of the guiding pad, the output end of the electric push rod pushes the pawl away from the ratchet wheel, releasing the engagement between the pawl and the ratchet wheel, enabling the ratchet wheel to rotate synchronously with the reel. At the same time, by using the power-on micro-start of the servo motor, the guiding pad is slightly tightened, so that after the guiding pad is unfolded, it can fit the artificial quartz stone plate material on the transmission belt. After the guiding pad is wound up, the output end of the electric push rod contracts to pull the pawl to engage with the ratchet wheel, effectively locking the rotation of the reel, preventing the guiding pad from rolling from the winding sleeve to between the vacuum pressing block and the transmission belt, avoiding the guiding pad from unfolding an excessive length and forming a fold on the top of the artificial quartz stone plate material, preventing mechanical fracture of the guiding pad, extending the service life of the guiding pad, and reducing the maintenance and use cost of the artificial quartz stone press.

[0024] 3. In this solution, when pulling one end of the guiding pad, the output end of the second motor drives the lead screw to rotate. The lead screw pushes the slider to reciprocate between the inner walls of the hollow frame through the sliding fit with the slider. At the same time, the sliding fit between the guide post and the infrared laser emitter guides one end of the guiding pad. Then the slider unfolds the guiding pad in the hollow frame by unidirectional pulling, so that the guiding pad is located between the vacuum pressing block and the transmission belt, and the pattern on the lower side of the guiding pad fits the artificial quartz stone plate material. By pulling one end of the guiding pad, the guiding pad can be accurately laid flat on the top of the artificial quartz stone plate material, and the gas can overflow evenly during the pressing process of the artificial quartz stone plate material, effectively improving the uniformity of the internal structure distribution of the artificial quartz stone plate.

[0025] 4. In this solution, when pressing and shaping the artificial quartz stone plate material, the output ends of the two retractable air cylinders press down the vacuum pressing block to fit the transmission belt. The two springs play a buffering role to offset the impact between the vacuum pressing block and the transmission belt or the vibrating plate, reducing the collision damage between the vacuum pressing block and the transmission belt or the vibrating plate, and achieving an improvement in the service life of the artificial quartz stone press.

There are two rollers 5, and the two rollers 5 are rotatably connected between the inner walls of the two shaft grooves 4, and the rotating shaft of one of the two rollers 5 extends to the other side end of the table board 2. The first motor 6 is fixedly connected to the side end of the table board 2, and the output end of the first motor 6 is fixedly connected to the extended shaft of the roller 5. The transmission belt 8 is sleeved on the circumferential surfaces of the vibrating plate 7 and the two rollers 5.

[0062] In the present invention, the mounting groove 3 is used to accommodate the vibration plate 7, and the vibration plate 7 is used to support part of the transmission belt 8. The top of the vibration plate 7 is lower than the top of the table plate 2. The vibration plate 7 and the top of the table plate 2 have a height difference to accommodate the artificial quartz stone plate material, and the vibration plate 7 is separated by the transmission belt 8 to apply high-frequency vibration to the artificial quartz stone plate material on the top of the transmission belt 8 to shake out the gas in the artificial quartz stone plate material. The two shaft grooves 4 are used to accommodate two rollers 5, and the two rollers 5 are used to tighten the transmission belt 8 and roll it. The first motor 6 is used to drive one of the two rollers 5 to rotate, and the transmission belt 8 is used to drive the artificial quartz stone plate material to move horizontally, so as to achieve rapid and smooth entry and exit of the artificial quartz stone plate.

[0063] A sealing strip 12 is fixedly connected to the bottom of the vacuum pressing block 11 .

[0064] In the present invention, the sealing strip 12 is used to fill the gap between the vacuum pressing block 11 and the transmission belt 8 or the guide pad 22, forming a sealed space between the vacuum pressing block 11 and the transmission belt 8 or the guide pad 22, thereby improving the vacuuming effect of the vacuum pressing block 11 on the artificial quartz stone plate raw material.

[0065] An air guide pattern 36 is formed at the bottom of the guide pad 22 .

[0066] In the present invention, the air guide pattern 36 can be customized with different patterns according to actual needs to meet the needs of pressing artificial quartz stones of different specifications. The air guide pattern 36 is opened to guide the force applied by the vacuum pressing block 11 to press down the artificial quartz stone plate material, so that the gas generated at the top of the artificial quartz stone plate material is quickly guided to both sides, thereby accelerating the gas discharge speed in the artificial quartz stone plate material.

[0067] The working process of an artificial quartz stone press provided by the present invention is as follows:

[0068] The raw materials of artificial quartz stone plates are evenly distributed on the top of the transmission belt 8. The first motor 6 is powered on and started, and the raw materials of artificial quartz stone plates are moved between the vibrating plate 7 and the vacuum pressing block 11. The second motor 19 is powered on and started. The output end of the second motor 19 drives the lead screw 18 to rotate. The lead screw 18 pushes the slider 16 to reciprocate between the inner walls of the hollow frame 13 through the sliding fit with the slider 16. At the same time, the sliding fit between the guide post 14 and the infrared laser emitter 17 guides one end of the guiding pad 22. Then the slider 16 unfolds the guiding pad 22 in the hollow frame 13 by unidirectionally pulling the guiding pad 22, so that the guiding pad 22 is located between the vacuum pressing block 11 and the transmission belt 8. The pattern on the lower side of the guiding pad 22 fits the raw materials of the artificial quartz stone plate. At the same time, when the guiding pad 22 moves, the servo motor 32 is powered on and slightly starts to rotate the winding wheel 23 to slightly tighten the guiding pad 22. Then the electric push rod 26 is powered on and started. The output end of the electric push rod 26 contracts and pulls the ratchet pawl 27 to engage and lock with the ratchet wheel 28 to limit the rotation of the winding wheel 23 and restrict the unfolding length of the guiding pad 22. Two shrinkage cylinders 10 are powered on and started. The two shrinkage cylinders 10 press down the vacuum pressing block 11, so that the guiding pad 22 under the vacuum pressing block 11 fits the transmission belt 8 and the vibrating plate 7. The negative pressure pump connected to the vacuum pressing block 11 is powered on, so that the space between the vacuum pressing block 11, the vibrating plate 7 and the transmission belt 8 is in a negative pressure state. At the same time, the vibrating plate 7 is powered on and started. The vibrating plate 7 performs high-frequency vibration on the raw materials of artificial quartz stone plates on the transmission belt 8, extruding the air between the particles of the raw materials of artificial quartz stone plates. At the same time, the air guiding pattern 36 on the lower side of the guiding pad 22 guides the extruded air to both sides and is exhausted by negative pressure. By guiding and exhausting the gas between the particles of the raw materials of artificial quartz stone plates, the small holes in the artificial quartz stone plates are reduced, and the structural strength of the artificial quartz stone plates is improved;

[0069] After the gas of the raw materials of artificial quartz stone plates is exhausted, the output ends of the two shrinkage cylinders 10 contract and pull the vacuum pressing block 11 to lift. Then the output end of the second motor 19 drives the lead screw 18 to rotate. The lead screw 18 pushes the pull rod 15 to reset through the sliding fit with the slider 16. The output end of the electric push rod 26 pushes the ratchet pawl 27 away from the ratchet wheel 28 to release the rotation restriction of the winding wheel 23. At the same time, the servo motor 32 is powered on and started. The output end of the servo motor 32 drives the driving gear 31 to rotate, so that the winding wheel 23 winds and wraps the other end of the guiding pad 22 through rotation until the guiding pad 22 is pulled out from between the vacuum pressing block 11 and the transmission belt 8. Then the two shrinkage cylinders 10 are powered on and started again. The two shrinkage cylinders 10 press down the vacuum pressing block 11, so that the vacuum pressing block 11 presses the raw materials of artificial quartz stone plates again to extrude and smooth the pattern scratches on the raw materials of artificial quartz stone plates, realizing the molding of the raw materials of artificial quartz stone plates.
