Description

[0001] This patent application claims priority to the Chinese utility model patent application with application number "2024200062505", title "A forming base for artificial stone slabs" and application date "2024.1.3". Technical Field

[0002] The utility model belongs to the technical field of artificial stone plate forming equipment, and in particular relates to a plate pressing base for artificial stone plates and a plate pressing device with the base. Background Art

[0003] In the prior art, artificial quartz panels are widely used and are often used to make cabinet countertops. Quartz countertops are highly popular because they are high hardness, high temperature resistance, acid and alkali resistance, impact resistance, and easy to clean. They do not contain any radioactive elements that are harmful to the human body. When making quartz countertops, the mixed fine powder and granular materials need to be evenly spread in the mold, and then pressed and formed by a press. The formed artificial stone panels can be sawed according to the corresponding product specifications.

[0004] Patents with announcement numbers CN208263468U and CN210617346U are both molding devices currently used by the applicant, and the effects are quite significant, but the above patents all have certain shortcomings.

[0005] Specifically, the mold is placed on a flat base, and the material in the mold is pressed by the press machine above. After pressing, the conveyor belt on the base can output it. The structure of the base is only a flat structure. This method can easily cause the upper layer of the material to be obviously compacted during pressing, but the material on the lower layer is not compacted obviously and is relatively loose. That is, the material cannot achieve a consistent compaction effect in the thickness direction, but a layered pressing effect with poor pressing uniformity. This will cause a more obvious difference in the effect of the top and bottom surfaces of the sheet after forming. More importantly, it will have a greater impact on the strength of the sheet and its service life will also be restricted. Utility Model Content

[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following Figures 1 to 8 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Reference Figures 3 to 7The utility model provides a plate pressing base, comprising a base 1, on which a supporting plate 3 for placing a mold is provided. The pressing mechanism is arranged directly above the supporting plate, so as to facilitate pressing of the material in the mold. Of course, in order to realize automatic transmission, a conveyor belt can also be arranged on the base. The top surface of the supporting plate 3 can be attached to the bottom surface of the conveyor belt located at the upper layer, so that the pressed mold can achieve the purpose of automatic transmission.

[0036] That is to say, there is a conveyor belt between the mold and the supporting plate 3. Since the conveyor belt is soft, even if the supporting plate 3 vibrates up and down, it will not cause interference. After pressing, the conveyor belt outputs the mold and synchronously inputs a new mold to achieve the purpose of automatic transmission.

[0037] The support plate 3 in the present invention is connected to at least one vibration device (in practice, a vibrator 44 can be selected as the power source of the vibration device, and it can be arranged on the bottom surface of the support plate 3). When the vibration device vibrates, it can drive the support plate 3 to vibrate up and down in the height direction. Of course, it is not a completely absolute up and down vibration, as long as the support plate 3 can be moved back and forth in the height direction in a horizontal state. Figure 8 The material in the mold 7 is vibrated by a certain frequency of the vibrator 44, so that the material is spread evenly during pressing, and the density of the plate after pressing is more consistent.

[0038] In addition to the above structure, the vibration device can also achieve vibration in an eccentric transmission manner, specifically: the support plate 3 is transmission-connected with at least one power shaft 2, and the power shaft 2 is axially rotated by a driving component (such as a driving motor or a hydraulic motor), thereby driving the linkage mechanism to transmit. In practice, two mutually horizontal and parallel corresponding power shafts 2 are mostly used, or four power shafts 2 can be used, which can provide better support for the stable up and down vibration of the support plate 3. The two power shafts 2 can be transmission-connected with the driving component respectively, or they can be transmission-connected with one driving component together. One driving component can be set, and components such as a transmission belt, a chain or a gear can be used to achieve synchronous and unidirectional transmission of the two power shafts 2. Two driving components can also be set, which is more expensive, but regardless of the increase or decrease in number, as long as the synchronous and unidirectional transmission of the two power shafts 2 can be achieved.

[0039] Of course, the power shafts 2 are preferably parallel to each other, and the rotation speed and direction are completely consistent. The power shaft 2 is connected to the base 1 through the bearing seat 21 to realize its own axial rotation.

[0040] For example, when producing a small-sized pressing base, only one vibrator or hydraulic motor can be provided, which saves costs and can also achieve a vibration effect on the height of the supporting plate 3. Of course, the power shaft 2 can also drive the linkage mechanism to drive only one.

[0041] It should be noted that when using a vibration device or a power shaft 2, it is best to use a limiting structure to further ensure that the supporting plate 3 performs reciprocating motion in the height direction in a horizontal state to prevent excessive pressure from tilting and warping in the horizontal direction, thereby ensuring that the thickness of the pressed plate is uniform.

[0042] In this embodiment, the support plate 3 is respectively connected to the power shaft 2 through a linkage mechanism, and is driven by the driving component to perform lifting and lowering motion in the height direction in a horizontal state, that is, the support plate 3 can form a vibration effect in the height direction, so that the material in the mold will be evenly spread and the density will be more consistent. This is consistent with the effect of vibrating the concrete with a vibrating rod after pouring the concrete, thereby ensuring that the density of the material after pressing is consistent and more durable.

[0043] This is significantly different from the traditional structure in which materials are compacted only by the pressing mechanism above. Through this structure, the material can be pressed from top to bottom and vibrated and spread at the bottom at the same time. The density of the material is guaranteed after pressing, and the service life of the board is longer.

[0044] The linkage mechanism in the utility model includes a fixed rotating disk 41 fixedly connected to the support plate 3, which is located on the bottom surface of the support plate 3. The fixed connection method can achieve the effect of integrated vibration of the two. The fixed rotating disk 41 is provided with an eccentric wheel 14 rotatably connected thereto. The two are rotatably connected, and a rotating bearing can also be installed between the two to achieve a smoother rotation effect. The eccentric wheel 14 is mutually connected to the power shaft 2. In this way, the power of the power shaft 2 will drive the eccentric wheel 14 to rotate eccentrically, and the fixed rotating disk 41 will also move eccentrically together.

[0045] Of course, in order to realize the vertical movement of the support plate 3 in a horizontal posture, it is preferable to set two fixed rotating disks 41 and eccentric wheels 1 4 on each power shaft 2, and the orientation and rotation speed of the eccentric wheels 1 should be consistent. In this way, the four eccentric wheels 1 4 are evenly arranged on the bottom surface of the support plate 3, and the horizontal posture of the support plate 3 can be vibrated up and down when rotating.

[0046] During the vibration process, the support plate 3 does not move in the up and down direction. Due to the use of the eccentric wheel, the vibration trajectory of the support plate 3 is consistent with the rotation trajectory of the eccentric wheel 1 4, and can move in a circular or elliptical motion trajectory. As for the frequency of the vibration, it can be adjusted by controlling the speed of the driving component or the size of the eccentric wheel 1.

[0047] The top surface of the base 1 is provided with a notch 11 for placing the support plate 3, that is, the support plate 3 can vibrate in the notch 11. This structure is also easy to process, that is, the top surface of the base can directly cut out the support plate 3, and the cut notch also forms the notch 11. Of course, the size of the notch 11 needs to be adjusted according to the vibration track of the support plate 3. The size of the notch 11 is larger than the size of the support plate 3, because when the eccentric wheel 4 is used to achieve vibration, there will also be a vibration track in the lateral direction. The notch 11 can adapt to the vibration track of the support plate 3 to prevent touching.

[0048] Reference Figure 1 to Figure 2 The utility model provides a plate pressing device, which includes the plate pressing base mentioned above, and a pressing mechanism is arranged above the plate pressing base. The pressing mechanism moves closer to the mold 7 on the plate pressing base or away from the mold 7 on the plate pressing base through a lifting component 52 (preferably a hydraulic cylinder). That is, the lifting component 52 can drive the pressing mechanism to press the material in the mold 7, thereby achieving the pressing of the plate. After pressing, the lifting is convenient for the mold to be replaced in and out.

[0049] In this embodiment, the pressing mechanism includes a housing 51, which is connected to a lifting component 52 to realize the lifting action of the housing 51. The housing 51 is provided with a pressing plate 53 located above the mold 7, and the pressing plate 53 is used to press the material in the mold 7. The pressing plate 53 is movably connected to the driving end of the pressing component 54 (preferably a hydraulic cylinder) and realizes the lifting action under the drive of the pressing component 54. The reason for adopting the movable connection is to provide a good activity space to prevent stress fracture damage caused by hard contact.

[0050] As a further improvement of this embodiment, a friction mechanism is also included, and this structure can apply linear reciprocating motion to the pressure plate 53.

[0051] Specifically, the friction mechanism includes a power component 61 (preferably a motor), and the driving end of the power component 61 is connected to the eccentric wheel 62 by transmission. Of course, the transmission connection is preferably a belt drive, or a chain or gear drive. The eccentric wheel 62 drives the pressure plate 53 to move linearly in the horizontal direction through the movable connecting rod 63. That is, one end of the movable connecting rod 63 is sleeved on the eccentric wheel 62 and is rotatably connected thereto, and the other end is hinged to the pressure plate 53 (see Figure 1 and Figure 2 ). When the eccentric wheel 2 62 rotates, it drives the movable connecting rod 63 to rotate. Since both ends of the movable connecting rod 63 are movably connected, the pressing plate 53 can perform reciprocating motion accordingly. At the same time, the pressing plate 53 is also pressed by the pressing component 54, so the pressing plate 53 can only perform linear reciprocating motion in the horizontal direction in a horizontal posture. While the material is pressed, it is also paved by friction in the horizontal direction.

[0052] Reference Figure 1 to Figure 2 Due to the adoption of this structure, the pressing plate 53 can be movably connected to the driving end of the pressing component 54 through the closing-shaped limit piece 531. As can be seen from the figure, the closing-shaped structure is to ensure that the pressing plate 53 is movably connected to the driving end and can also rise and fall with the driving end.

[0053] In the above structure, in order to achieve the deceleration effect, the driving end of the power component 61 is connected to the reduction wheel 64 by transmission. Of course, the transmission connection mode is preferably belt transmission, and it can also be chain or gear transmission. The transmission shaft 65 coaxially driven with the reduction wheel 64 is connected to the eccentric wheel 2 62, so as to achieve the purpose of deceleration transmission. Of course, the power component 61 can also be changed to a motor with a deceleration function.

[0054] The utility model adopts vibration in the height direction to realize the uniform spreading of the material in the mold, especially making the bottom flow of the material more uniform during pressing, the pressing effect of the material in the thickness direction is uniform and without difference, the density of the plate after final forming is consistent, and the support and strength are further guaranteed.

[0055] In actual use, eccentric wheels are set at both ends of each power shaft, and four eccentric wheels are set on the two power shafts. These four eccentric wheels rotate synchronously in the same direction, so that the supporting plate can be lifted and lowered in the height direction in a horizontal state. That is, the mold can be placed horizontally and vibrated rapidly in height, so that the material in the mold can be evenly spread during the pressing process, the layered flow of the material is more uniform and dense, and the plate can be evenly pressed and formed.
