Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a continuous forming equipment for the production of ceramic plates. Background Technology

[0002] A ceramic brick press is a device that uses a pressure system to press ceramic powder into shape. Currently, most ceramic manufacturers use traditional ceramic brick presses, which are mainly divided into the following types: beam-column type, wire-wound type, and plate-frame type. The traditional production mode of a ceramic brick press often involves first feeding the powder, then pushing it into the mold frame, and finally, the moving beam pressing the powder. In this case, the ceramic brick press needs to wait for the feeding to complete before each pressing operation, making it an intermittent production method, which is not conducive to improving production efficiency. Furthermore, these types of ceramic brick presses are all based on Pascal's principle. During operation, oil is first poured into the main cylinder, then the main piston rod moves, driving the moving beam, which has the mold core installed, to apply downward pressure. At this time, the mold core contacts the powder inside the mold frame and gradually increases pressure, forming the powder. In this mode, to ensure sufficient forming pressure for the ceramic bricks, the main piston rod needs to continuously apply pressure to the moving beam; therefore, the machine frame often needs to withstand the enormous pressure generated by the oil cylinder. Therefore, the frame of a ceramic brick press needs to withstand enormous alternating stress during operation, making it prone to stress fatigue. Furthermore, as the forming pressure of the ceramic brick press increases, the corresponding volumes of the frame, main cylinder, and main piston need to be increased, which brings certain challenges to production, processing, transportation, and maintenance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a continuous forming equipment for ceramic plate production, which can realize continuous production, improve production efficiency, and obtain a large pressing force with a small driving force, thereby reducing the stress on the frame and extending the service life.

[0004] In addition, a single active drive device can be used to achieve the simultaneous movement of multiple rollers, thereby achieving uniform pressure and cost savings.

[0005] To solve the above-mentioned technical problems, the present invention provides a continuous forming equipment for ceramic slab production, which is used to continuously form powder, including a frame, a conveying device and a pressing device. The conveying device includes a conveying component, which runs between the feeding station, the pressing station and the discharging station of the continuous forming equipment for ceramic slab production, and the powder is placed on the conveying component.

[0006] The pressing device is located above the powder. The pressing device includes a support frame, a front pressing mechanism, a rear pressing mechanism, and a lever pressing mechanism connected sequentially to the support frame along the conveying direction of the conveyor. The vertical distance from the front pressing mechanism to the conveyor is greater than the vertical distance from the rear pressing mechanism to the conveyor. When the conveyor moves the powder, the front pressing mechanism and the rear pressing mechanism can press and shape the powder. The front pressing mechanism is connected to the frame. The movable end of the lever pressing mechanism can drive the support frame to swing up and down around the front pressing mechanism and drive the rear pressing mechanism to move up and down.

[0007] As an improvement to the above solution, the front pressure mechanism is located at one end of the support frame near the feeding station, the lever pressure mechanism is located at the other end of the support frame, and the rear pressure mechanism is located between the front pressure mechanism and the lever pressure mechanism.

[0008] As an improvement to the above solution, the front pressure mechanism includes a front bearing housing and a low-pressure roller. The front bearing housing is connected to the frame, the support frame is hinged to the front bearing housing, the support frame can swing around the front bearing housing, the low-pressure roller is hinged to the front bearing housing, and the bottom of the low-pressure roller can apply pressure to the powder.

[0009] As an improvement to the above solution, the pressure application device further includes a height adjustment mechanism, which is connected to the front pressure application mechanism and the lever pressure application mechanism respectively. The height adjustment mechanism is respectively located between the front bearing housing and the frame and between the lever pressure application mechanism and the frame. The height adjustment mechanism can adjust the vertical distance between the front bearing housing and the transmission component and the vertical distance between the lever pressure application mechanism and the transmission component.

[0010] As an improvement to the above solution, the height adjustment mechanism includes an adjustment seat and an adjustment rod. The front bearing seat and the lever pressure mechanism are fixed on the adjustment seat, and the adjustment rod is vertically arranged on the frame. The adjustment seat can be connected to the frame through the adjustment rod, and the adjustment rod can adjust the vertical distance between the front bearing seat and the transmission component, as well as the vertical distance between the lever pressure mechanism and the transmission component.

[0011] As an improvement to the above solution, the lever pressure mechanism includes a driving component and a transmission component. The movable end of the driving component is connected to the transmission component. The driving component is fixed on the adjusting seat. One end of the support frame is hinged to the transmission component. The driving component can drive the transmission component to raise or lower the support frame. The adjusting rod can adjust the vertical distance between the driving component and the transmission component.

[0012] As an improvement to the above solution, the lever pressure mechanism includes a first rear magnetic plate and a second rear magnetic plate. One end of the support frame is hinged to the first rear magnetic plate, and the second rear magnetic plate is disposed on the adjustment seat. The second rear magnetic plate is provided with an energized coil. After being energized, the first rear magnetic plate can move closer to the second rear magnetic plate, and the adjustment rod can adjust the vertical distance between the second rear magnetic plate and the transmission component.

[0013] As an improvement to the above solution, the rear pressure mechanism includes at least one pressure roller and a corresponding rear bearing seat. The pressure roller is hinged to the rear bearing seat, and the rear bearing seat is connected to the support frame. The rear bearing seat can move with the support frame. The vertical distance from the pressure roller to the conveying component is less than the vertical distance from the low-pressure roller to the conveying component. The pressure roller can press the powder.

[0014] As an improvement to the above solution, there are multiple pressure rollers, which are sequentially fixed to the support frame via the rear bearing seat. Among two adjacent pressure rollers, the vertical distance from the pressure roller closer to the lever pressure mechanism to the conveyor is not greater than the vertical distance from the pressure roller closer to the front pressure mechanism to the conveyor.

[0015] As an improvement to the above scheme, the number of pressure rollers is two, namely a medium-pressure roller and a high-pressure roller. The medium-pressure roller and the high-pressure roller are respectively hinged to the rear bearing seat. The medium-pressure roller and the high-pressure roller are located between the low-pressure roller and the lever pressure mechanism. The medium-pressure roller is located between the low-pressure roller and the high-pressure roller.

[0016] As an improvement to the above solution, the pressure applying device further includes a linkage mechanism, which includes a drive roller, a linkage belt, and a pressure wheel. The drive roller is connected to the support frame. The linkage belt is wound around the sides of the drive roller, the low-pressure roller, and the pressure applying roller, with its ends touching the ground. The pressure wheel abuts against the linkage belt to tension the linkage belt. The drive roller can drive the low-pressure roller and the pressure applying roller to rotate cyclically through the linkage belt.

[0017] As an improvement to the above solution, the continuous forming equipment for ceramic plate production further includes a side baffle device. The side baffle device includes a side baffle mechanism, which includes a side baffle frame and a side baffle cylinder. The side baffle cylinder is vertically hinged to the side baffle frame and is distributed on both sides of the conveyor. The side baffle cylinder can apply pressure to the powder from both sides of the conveyor. When the powder moves with the conveyor, the side baffle cylinder can rotate.

[0018] As an improvement to the above solution, the side guard device further includes a connecting mechanism, which includes a first gear and a second gear that mesh with each other. The first gear is connected to the side guard cylinder, and the second gear is connected to the pressure roller. When the pressure roller rolls, it can drive the side guard cylinder to roll.

[0019] As an improvement to the above solution, the continuous forming equipment for ceramic plate production further includes a pressure holding device. The pressure holding device is located between the rear pressure applying mechanism and the discharge station. The pressure holding device includes an upper clamping plate, a lower clamping plate, and an adjusting screw. The upper clamping plate, the lower clamping plate, and the conveying component are arranged in parallel. A pressure holding channel is formed between the upper clamping plate and the lower clamping plate, through which the powder can pass. The pressure holding channel can maintain pressure on the powder. The lower clamping plate is fixed to the frame. The adjusting screw is vertically connected between the upper clamping plate and the lower clamping plate, and can adjust the distance between the upper clamping plate and the lower clamping plate.

[0020] Implementing this invention has the following beneficial effects:

[0021] The present invention provides a continuous forming equipment for ceramic slab production, which includes a conveying device and a pressing device. The conveying device includes a conveyor, in which the powder is placed. The conveyor can transport the powder from the feeding station to the discharging station. During the transport process, the front pressing mechanism and the rear pressing mechanism of the pressing device can respectively roll the powder, thereby pressing the powder into shape. During the production process, the powder can be continuously added from the feeding station, enabling the continuous forming equipment for ceramic slab production to continuously press the powder, thereby achieving continuous production and improving production efficiency.

[0022] Furthermore, since the front pressure mechanism is located at one end of the support frame near the feeding station, the lever pressure mechanism is located at the other end of the support frame, and the rear pressure mechanism is located between the front pressure mechanism and the lever pressure mechanism, the front pressure mechanism, the rear pressure mechanism, the support frame, and the lever pressure mechanism form a force-saving lever structure. When applying downward pressure to the powder, the lever pressure mechanism only needs to apply a small force to obtain a large pressing force in the rear pressure mechanism, thereby reducing the stress on the frame and reducing the power consumption of the lever pressure mechanism, saving energy, and reducing the cylinder volume.

[0023] Furthermore, the rear pressing mechanism includes at least one pressing roller. Among two adjacent pressing rollers, the vertical distance from the pressing roller closer to the lever pressing mechanism to the conveying component is not greater than the vertical distance from the pressing roller closer to the front pressing mechanism to the conveying component. This allows multiple pressing rollers to gradually apply high pressure to the powder. By reasonably setting the vertical distance from the pressing roller to the conveying component, the pressure of each pressing roller on the powder can be controlled, thereby ensuring the pressing effect of the entire continuous pressing process.

[0024] In addition, the pressure application device also includes a linkage mechanism. The linkage mechanism uses the active roller to drive the entire low-pressure roller and the pressure roller. The linkage belt makes the low-pressure roller and the pressure roller rotate together, which can accurately and stably ensure that the linear speed between each roller is consistent, so that the transmission process speed is consistent, ensuring the uniformity and high efficiency of pressing.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0032] See Figure 1The first embodiment of this invention discloses a continuous forming equipment for ceramic slab production, used for continuously forming powder 6. The continuous forming equipment for ceramic slab production includes a frame 5, a conveying device 4, and a pressing device 1. The conveying device 4 and the pressing device 1 are fixed to the frame 5. The conveying device 4 includes a conveyor 41, which can be a conveyor plate, conveyor belt, etc., with material transport characteristics. In this embodiment, the conveyor 41 is preferably a circulating conveyor belt. The conveyor 41 runs between the feeding station 7, the pressing station 9, and the discharging station 8 of the continuous forming equipment for ceramic slab production. The powder 6 is placed on the conveyor 41. The powder 6 is fed from the feeding station 7 onto the conveyor 41, and can follow the conveyor 41 sequentially from the feeding station 7 to the pressing station 9 for pressing, and then from the pressing station 9 to the discharging station 8, finally being discharged from the discharging station 8. During the operation of the powder 6, the pressing device 1 can roll the powder 6 to compress it into shape.

[0033] Specifically, the pressing device 1 is located above the powder 6 and above the pressing station 9. The pressing device 1 includes a support frame 16, a front pressing mechanism 11, a rear pressing mechanism 12, and a lever pressing mechanism 13 sequentially connected to the support frame 16 along the conveying direction of the conveyor 41. The front pressing mechanism 11 and the rear pressing mechanism 12 are used to press the powder 6, and the lever pressing mechanism 13 is used to provide the driving force required for the roller pressing of the front pressing mechanism 11 and the rear pressing mechanism 12. The front pressing mechanism 11 is close to the feeding station 7, and the rear pressing mechanism 12 is close to the discharging station 8. Therefore, the powder... The powder 6 first passes through the front pressing mechanism 11 and then the rear pressing mechanism 12. The vertical distance from the front pressing mechanism 11 to the conveyor 41 is greater than the vertical distance from the rear pressing mechanism 12 to the conveyor 41. Therefore, the front pressing mechanism 11 applies a lower degree of pressure to the powder 6, while the rear pressing mechanism 12 applies a higher degree of pressure. During pressing, the front pressing mechanism 11 applies less pressure to the powder 6, which can squeeze out the air between the powder particles. After squeezing out the air, the rear pressing mechanism 12 applies more pressure to the powder 6, which can further press the powder 6 and finally shape it. Therefore, when the conveyor 41 moves the powder 6, the front pressing mechanism 11 and the rear pressing mechanism 12 can continuously press and shape the powder 6. During production, the powder 6 can be continuously fed into the feeding station 7, and the conveyor 41 can continuously deliver the powder 6 to the front pressing mechanism 11 and the rear pressing mechanism 12 for pressing. The entire process is uninterrupted, thus achieving continuous pressing. The front pressing mechanism 11 is connected to the frame 5 and can perform pre-pressing. The movable end of the lever pressing mechanism 13 can drive the support frame 16 to swing up and down around the front pressing mechanism 11 and drive the rear pressing mechanism 12 to move up and down. While moving up and down, the rear pressing mechanism 12 can increase or decrease the roller pressure, thereby achieving pressurization or depressurization of the powder 6.

[0034] The beneficial effects of the first embodiment of the present invention are as follows:

[0035] The first embodiment of the present invention provides a continuous forming equipment for ceramic slab production, which includes a conveying device 4 and a pressing device 1. The conveying device 4 includes a conveying component 41. During operation, the powder 6 is first placed in the conveying component 41, and then the conveying component 41 can transport the powder 6 from the feeding station 7 to the discharging station 8. During the transportation process, the front pressing mechanism 11 and the rear pressing mechanism 12 of the pressing device 1 can respectively roll the powder 6, thereby pressing the powder 6 into shape. During the production process, the powder 6 can be continuously added from the feeding station 7, so that the continuous forming equipment for ceramic slab production can continuously press the powder 6, thereby realizing continuous production and improving production efficiency.

[0036] The front pressure mechanism 11 is located at one end of the support frame 16 near the feeding station 7, the lever pressure mechanism 13 is located at the other end of the support frame 16, and the rear pressure mechanism 12 is located between the front pressure mechanism 11 and the lever pressure mechanism 13. The lever pressure mechanism 13, the support frame 16, the front pressure mechanism 11, and the rear pressure mechanism 12 form a lever structure. The front pressure mechanism 11 acts as a fulcrum, and the rear pressure mechanism 12 bears the reaction force from the powder 6, thus creating resistance to the support frame 16. The lever pressure mechanism 13 can apply power to the support frame 16. Since the front pressure mechanism 11, the rear pressure mechanism 12, and the lever pressure mechanism 13 are arranged sequentially, the distance from the lever pressure mechanism 13 to the front pressure mechanism 11 is greater than the distance from the rear pressure mechanism 12 to the front pressure mechanism 11. This results in a power arm that is greater than the resistance arm, forming a force-saving lever structure. This structure can obtain a larger pressing force with a smaller driving force, thereby reducing the stress on the frame 5 and reducing the power consumption of the lever pressure mechanism 13, saving energy, reducing the cylinder volume, and reducing processing difficulty.

[0037] The front pressure mechanism 11 includes a front bearing seat 111 and a low-pressure roller 112. The front bearing seat 111 is connected to the frame 5, and the low-pressure roller 112 is hinged to the front bearing seat 111 via a bearing. The support frame 16 is hinged to the bearing seat. The front bearing seat 111 serves as the "fulcrum" in the aforementioned force-saving lever structure, and the support frame 16 can swing around the front bearing seat 111. As the powder 6 follows the conveyor 41 toward the discharge station 8, the bottom of the low-pressure roller 112 can roll and press the powder 6, squeezing out the air from the powder 6. While rolling and pressing the powder 6, the low-pressure roller 112 can roll, and under the action of friction, it will assist the conveyor 41 in pushing the powder 6 backward, thereby facilitating the pushing of the powder into the rear pressure mechanism with higher pressure.

[0038] The pressure application device 1 further includes a height adjustment mechanism 14, which is connected to the front pressure application mechanism 11 and the lever pressure application mechanism 13. The height adjustment mechanism 14 can be used to adjust the height of the front pressure application mechanism 11 and the lever pressure application mechanism 13, thereby adjusting the front compression amount and the rear compression amount of the powder 6, and can compress different powders 6. The height adjustment mechanism 14 is respectively located between the front bearing seat 111 and the frame 5 and between the lever pressure application mechanism 13 and the frame 5. The height adjustment mechanism 14 can adjust the vertical distance between the front bearing seat 111 and the conveyor 41, thereby adjusting the compression amount of the front pressure application mechanism 11. The height adjustment mechanism 14 can also adjust the vertical distance between the lever pressure application mechanism 13 and the conveyor 41, thereby adjusting the compression amount of the rear pressure application mechanism 12.

[0039] The height adjustment mechanism 14 includes an adjustment seat 141 and an adjustment rod 142. The front bearing seat 111 is fixed on the adjustment seat 141, and the adjustment rod 142 is vertically arranged on the frame 5. The adjustment rod 142 can be a threaded long rod. The adjustment seat 141 can be connected to the frame 5 through the adjustment rod 142. By rotating the thread, the adjustment rod 142 can adjust the distance between the adjustment seat 141 and the frame 5, thereby changing the height of the front bearing seat 111 and the lever pressure mechanism 13, and changing the height of the low-pressure roller 112.

[0040] In the first embodiment, the lever pressure mechanism 13 includes a driving member 131 and a transmission member 132. The movable end of the driving member 131 is connected to the transmission member 132. The driving member 131 can be a mechanism or device with linear reciprocating motion characteristics, such as a motor, hydraulic cylinder, or pneumatic cylinder. In this embodiment, the driving member 131 is preferably a hydraulic cylinder. The driving member 131 is fixed on the adjusting seat 141. By rotating the adjusting rod 142, the adjusting seat 131 can move up and down to change the distance between the adjusting seat 131 and the frame 5, that is, to change the height of the hinged end of the support frame 16, thereby changing the compression amount of the rear pressure mechanism 12. One end of the support frame 16 is hinged to the transmission member 132. The driving member 131 can drive the transmission member 132 to raise or lower the support frame 16, thereby controlling the rear pressure mechanism 12 to pressurize or depressurize the powder 6. In this embodiment, the fixed position of the driving member 131 is located below the driving member 131, and the driving member 131 can drive the transmission member 132 to move above the driving member 131.

[0041] The rear pressing mechanism 12 includes at least one pressing roller 124 and a corresponding rear bearing seat 123. The pressing roller 124 is hinged to the rear bearing seat 123, and the rear bearing seat 123 is connected to the support frame 16. The rear bearing seat 123 can move with the support frame 16. The vertical distance from the pressing roller 124 to the conveying member 41 is less than the vertical distance from the low-pressure roller 112 to the conveying member 41. The pressing roller 124 can press the powder. Since the height of the pressing roller 124 is lower than the height of the low-pressure roller 112, the pressing roller 124 can apply higher pressure to the powder 6 during pressing, thereby enabling the powder 6 to complete the process from low-pressure pressing to high-pressure pressing. To make the pressing process more precise and controllable, there can be multiple pressing rollers 124. Multiple pressing rollers 124 are fixed to the support frame 16 in sequence through the rear bearing seat 123. During the entire conveying process, multiple pressing rollers 124 can continuously and uniformly press the powder 6, thereby achieving a better continuous pressing and forming effect. In two adjacent pressure rollers 124, the vertical distance from the pressure roller 124 closer to the lever pressure mechanism 13 to the conveyor 41 is not greater than the vertical distance from the pressure roller 124 closer to the front pressure mechanism 11 to the conveyor 41. That is, in the direction from the front pressure mechanism 11 to the lever pressure mechanism 13, the height of the previous pressure roller 124 is not lower than the height of the next pressure roller 124. By reasonably setting the pressure rollers 124, the pressing pressure can be gradually increased. In combination with the conveying speed of the conveyor 41, the pressure change of the powder 6 during continuous pressing can be controlled, thereby accurately controlling the continuous pressing process.

[0042] In the first embodiment, there are two pressure rollers 124, namely a medium-pressure roller 121 and a high-pressure roller 122. That is, the rear pressure mechanism 12 includes a medium-pressure roller 121, a high-pressure roller 122, and a rear bearing seat 123. The medium-pressure roller 121 and the high-pressure roller 122 divide the rolling process of the rear pressure mechanism 12 into two processes. The medium-pressure roller 121 is responsible for outputting a larger pressure, and the high-pressure roller 122 is responsible for outputting the maximum pressure. The medium-pressure roller 121 and the high-pressure roller 122 are respectively hinged to the rear bearing seat 123, and the rear bearing seat 123 is connected to the support frame. On the support frame 16, the rear bearing seat 123 can move along with the support frame 16. Therefore, the support frame 16 can simultaneously drive the intermediate pressure roller 121 and the high pressure roller 122. During the process of the support frame 16 driving the intermediate pressure roller 121 and the high pressure roller 122 to press downwards, the bottom of the intermediate pressure roller 121 and the high pressure roller 122 can roll the powder 6. Moreover, the lever pressing mechanism 13 can continuously apply pressure through the support frame 16, so that the intermediate pressure roller 121 and the high pressure roller 122 continuously press the powder 6, ultimately pressing the powder 6 into a ceramic tile blank. When the powder 6 moves with the conveyor 41, the intermediate pressure roller 121 and the high pressure roller 122 will roll. Therefore, under the action of friction, the powder 6 can move more easily, which is beneficial to the subsequent rolling process.

[0043] The intermediate-pressure roller 121 is located between the low-pressure roller 112 and the high-pressure roller 122. The vertical distance from the intermediate-pressure roller 121 to the conveyor 41 is smaller than the vertical distance from the low-pressure roller 112 to the conveyor 41, and the vertical distance from the high-pressure roller 122 to the conveyor 41 is smaller than the vertical distance from the intermediate-pressure roller 121 to the conveyor 41. Therefore, by controlling the vertical distances from the low-pressure roller 112, the intermediate-pressure roller 121, and the high-pressure roller 122 to the conveyor 41, the pressing force of the powder 6 can be controlled. The low-pressure roller 112 is higher and has a lower pressing force, the intermediate-pressure roller 121 is lower and has a higher pressing force, and the high-pressure roller 122 is the lowest and has the highest pressing force. During operation, the powder 6 is sequentially pressed by the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122, achieving a continuous pressing process from low pressure to medium pressure and then to high pressure. This enables continuous production and ensures that the powder 6 can be properly pressed and shaped. In other embodiments, the post-pressing mechanism 12 may further include multiple rollers with different heights distributed on the support frame 16 to achieve a more refined and smoother pressure transition effect.

[0044] See Figure 2The continuous forming equipment for ceramic slab production also includes a pressure holding device 3, which is located between the post-pressing mechanism 12 and the discharge station 8. The pressure holding device 3 is used to hold pressure on the ceramic tile blank pressed from the high-pressure roller 122 to ensure the pressing effect. The pressure-holding device 3 includes an upper clamping plate 31, a lower clamping plate 32, and an adjusting screw 33. The upper clamping plate 31, the lower clamping plate 32, and the conveying member 41 are arranged in parallel. A pressure-holding channel 34 is formed between the upper clamping plate 31 and the lower clamping plate 32. The powder 6 can pass through the pressure-holding channel 34. During the process of the powder 6 passing through the pressure-holding channel 34, the pressure-holding channel 34 can maintain the pressure of the powder 6. The lower clamping plate 32 is fixed on the frame 5. The adjusting screw 33 is vertically connected between the upper clamping plate 31 and the lower clamping plate 32. By rotating the adjusting screw 33, the distance between the upper clamping plate 31 and the lower clamping plate 32 can be adjusted, thereby controlling the pressure of the powder 6. In other embodiments, a pressure sensor and a displacement sensor can be provided on the upper clamping plate 31. During the pressure holding process, the pressure sensor and the displacement sensor can respectively detect the pressure on the powder 6 and the height of the pressure holding channel 34. By adjusting the control system, the upper clamping plate 31 can be moved to coordinately control the height of the pressure holding channel 34 and the pressure holding pressure of the powder 6, thereby achieving the effect of intelligent pressure holding.

[0045] To uniformly control the rolling of the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122, and to ensure continuous pressing, the pressing device 1 further includes a linkage mechanism 15. The linkage mechanism 15 includes a drive roller 153, a linkage belt 151, and a pressure wheel 152. The drive roller 153 is externally driven, and the linkage belt 151 can be a transmission chain, transmission belt, or other components with transmission functions. The drive roller 153 is connected to the support frame 16. When the support frame 16 swings up and down, it drives the drive roller 153 to move. The linkage belt 151 is connected end-to-end. The pressure roller 152 simultaneously wraps around the sides of the active roller 153, the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122. The pressure roller 152 abuts against the linkage belt 151 to tension the linkage belt 151. When the active roller 153 rolls, it can drive the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122 to rotate in a cycle through the linkage belt 151. This can accurately and stably ensure that the linear speed between each roller is consistent, so as to assist the conveyor 41 in feeding the powder 6 into each pressing mechanism to ensure the uniformity and high efficiency of pressing. Simultaneously, the linkage belt 151 can continuously press the powder 6 in place of the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122. Between the low-pressure roller 112, the medium-pressure roller 121, and the high-pressure roller 122, under the pressing action of the pressure roller 152, the linkage belt 151 can continuously apply pressure to the powder 6, allowing the powder 6 to maintain its shape after pressing, thus achieving a pressure-holding effect after pressing. The cooperation of the active roller 153, the linkage belt 151, the medium-pressure roller 121, and the high-pressure roller 122 enables continuous pressing of the powder 6 during continuous feeding. Furthermore, by utilizing the gradual pressure increase effect of the medium-pressure roller 121 and the high-pressure roller 122, the effect of maintaining a consistent rotational linear speed of each roller by the active roller 153 and the linkage belt 151, and the effect of continuous pressure holding after pressing, continuous and uniform pressure pressing can be achieved, resulting in high pressing efficiency and pressing quality.

[0046] See Figure 3To prevent the powder 6 from collapsing and overflowing towards both sides of the conveyor 41 during pressing and to ensure the pressing effect, the continuous forming equipment for ceramic plate production also includes a side baffle device 2. The side baffle device 2 includes a side baffle mechanism 21, which includes a side baffle frame 211 and a side baffle cylinder 212. The side baffle frame 211 is used to fix the side baffle cylinder 212. The side baffle cylinder 212 is vertically hinged to the side baffle frame 211. The side baffle cylinder 212 is distributed on both sides of the conveyor 41. The side baffle cylinder 212 can roll the powder 6 from both sides of the conveyor 41. The outer layer of the side baffle cylinder 212 is preferably an inflatable rubber layer, which can flexibly block the sides of the powder 6. When the powder 6 moves with the conveyor 41, the side baffle cylinder 212 can roll with the powder 6 due to friction. There can be multiple side-blocking mechanisms 21, which are distributed at any position on both sides of the powder 6, and can block the powder 6 at multiple positions. In this embodiment, there is only one side-blocking mechanism 21.

[0047] See Figure 4 The present invention also discloses a second embodiment, which differs from the first embodiment in that the driving component 131 is suspended on the frame 5, the fixed position of the driving component 131 is located above the driving component 131, and the driving component 131 can drive the transmission component 132 to move below the driving component 131.

[0048] See Figure 5The present invention also discloses a third embodiment. Unlike the first embodiment, the second embodiment adds a connecting mechanism 22 to the first embodiment. The connecting mechanism 22 enables the rear pressure mechanism 12 to be linked with the side stop mechanism 21. The connecting mechanism 22 includes a first gear 221 and a second gear 222 that mesh with each other. The first gear 221 is connected to the side stop cylinder 212, and the second gear 222 is connected to the pressure roller 124. In this embodiment, the second gear 222 is connected to the intermediate pressure roller 121 or the high pressure roller 122. Since the side stop cylinder 212 is vertically hinged to the side stop frame 211, and the intermediate pressure roller 121 or the high pressure roller 122 is horizontally hinged to the support frame 16, and the axes of the side stop cylinder 212 and the intermediate pressure roller 121 or the high pressure roller 122 are perpendicular to each other, the first gear 221 and the second gear 222 are perpendicularly connected to each other. The first gear 221 and the second gear 222 can be bevel gears to achieve a vertical connection. As the powder 6 moves with the conveyor 41, the medium-pressure roller 121 or the high-pressure roller 122 will roll along with it. At the same time, under the transmission action of the first gear 221 and the second gear 222, the rolling of the medium-pressure roller 121 or the high-pressure roller 122 can drive the side-block cylinder 212 to roll, thereby reducing the relative displacement between the powder 6 and the side-block cylinder 212.

[0049] See Figure 6 The present invention also discloses a fourth embodiment. The height adjustment mechanism 14 of the third embodiment is different from the lever pressure mechanism 13 of the first embodiment. Specifically, the lever pressure mechanism 13 includes a first rear magnetic plate 133 and a second rear magnetic plate 134. One end of the support frame 16 is hinged to the first rear magnetic plate 133. The second rear magnetic plate 134 is disposed on the adjustment seat 141. The adjustment seat 141 can adjust the height of the second rear magnetic plate 134, thereby adjusting the compression amount of the rear pressure mechanism 12. In order to drive the rear pressure mechanism 12, a gap is provided between the second rear magnetic plate 134 and the first rear magnetic plate 133. The second rear magnetic plate 134 is provided with an energized coil, which can be connected to an external power source to be energized. After being energized, a magnetic field can be generated between the first rear magnetic plate 133 and the second rear magnetic plate 134, so that an attraction is generated between the second rear magnetic plate 134 and the first rear magnetic plate 133, thereby driving the second rear magnetic plate 134 to move closer to the first rear magnetic plate 133 to generate a pressing force. By changing the current of the energized coil, the magnitude of the magnetic field force between the first rear magnetic plate 133 and the second rear magnetic plate 134 can be changed, thereby changing the pressing force.

[0050] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
