Description

Technical Field

[0001] This utility model relates to the field of artificial stone processing technology, and in particular to a rapid demolding auxiliary device for an artificial stone press. Background Technology

[0002] Artificial stone, as a new type of material widely used in building decoration, kitchen and bathroom countertops, etc., usually includes key processes such as batching, mixing, pressing, curing, and polishing. Among them, the pressing process is completed in a large press, where the mixed raw materials are pressed into shape under high pressure. After pressing, the formed artificial stone slab needs to be removed from the press mold, a process called demolding.

[0003] Currently, in the artificial stone production industry, the traditional demolding method mainly relies on manual operation. Specifically, it usually involves two or more workers using simple tools such as crowbars and iron sheets to insert them into the gaps at the edge of the stone slab. Through leverage and vibration, the stone slab is forcibly pried out of the press body, or simple external auxiliary devices are used to demold the stone slab.

[0004] In most existing technologies, artificial stone is demolded manually or by some simple auxiliary equipment. The operation mode is mostly fixed, which makes it difficult to adapt to the production of artificial stone slabs of different specifications and shapes. When the production line needs to switch to produce products of different sizes or shapes, it often requires a major adjustment to the operation process, or even a complex mechanical modification or replacement of auxiliary equipment. This not only takes a long time, but also affects production efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a quick demolding auxiliary device for an artificial stone press, which can effectively solve the problems mentioned above. In most existing technologies, the manual demolding methods or some simple auxiliary equipment for artificial stone are mostly fixed in operation mode, which is difficult to adapt to the production of artificial stone slabs of different specifications and shapes. When the production line needs to switch to produce products of different sizes or shapes, it is often necessary to make significant adjustments to the operation process, or even to carry out complex mechanical modifications or replacements of auxiliary equipment. This not only consumes a lot of time, but also affects production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A quick demolding auxiliary device for an artificial stone press includes a press body, a stone slab on the inner surface of the press body, an adsorption mechanism at each of the four corners of the top of the stone slab, a telescopic adjustment mechanism installed on the opposite sides of several adsorption mechanisms, a front-to-back displacement mechanism installed at the opposite ends of several telescopic adjustment mechanisms, a vertical displacement mechanism installed at the rear end of the front-to-back displacement mechanism, and a drive component installed at the bottom of the vertical displacement mechanism.

[0008] Preferably, a movable component is installed at the bottom of the drive component, and a locking universal wheel is installed at each of the four corners of the bottom of the movable component.

[0009] Preferably, each of the adsorption mechanisms includes a negative pressure suction cup assembly, a negative pressure pump is installed on the top of each of the negative pressure suction cup assemblies, and a mounting plate is installed on the upper side of the outer surface of the negative pressure suction cup assembly.

[0010] Preferably, each of the telescopic adjustment mechanisms includes two mounting seats, and the electric telescopic rod assembly is mounted on the opposite sides of the two mounting seats located on the same side.

[0011] Preferably, the front-to-back displacement mechanism includes a mounting frustum, a fixed bracket is mounted on the top of the mounting frustum, a hydraulic telescopic cylinder is mounted on the rear end of the fixed bracket, and two mounting seats on the same side are respectively mounted to the mounting frame plate and the mounting frustum.

[0012] Preferably, the vertical displacement mechanism includes a limiting slide, the inner surface of which is provided with a movable seat, the movable seat is installed at the rear end of the hydraulic telescopic cylinder, and the inner surface of the movable seat is threadedly connected with a threaded rod.

[0013] Preferably, the drive assembly includes a rotating shaft mounted on the bottom of a threaded rod, a bevel gear set mounted on the bottom of the rotating shaft, a drive shaft mounted on the left end of the bevel gear set, and a drive motor mounted on the left end of the drive shaft.

[0014] Preferably, the moving component includes a base plate, with protective inclined blocks symmetrically installed on the top of the base plate. Two of the protective inclined blocks are respectively installed on the front and rear sides of the bottom of the limiting slide. The bottom of the drive motor is installed on the left side of the top of the base plate. A handle is installed on the right side of the top of the base plate near the protective inclined blocks. Several locking casters are respectively installed at the four corners of the bottom of the base plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device utilizes a designed adsorption mechanism that applies negative pressure to the stone slab. With the cooperation of front-to-back and up-and-down displacement mechanisms, the stone slab can be pulled out of the press body, achieving rapid demolding. This reduces the safety risks associated with workers using tools like pry bars for demolding, such as injuries from impacts, cuts, and muscle strains. Furthermore, the adsorption mechanism employs a matrix-type suction cup, allowing for adjustment of the adsorption area via a telescopic adjustment mechanism to accommodate artificial stone slabs of different sizes and even shapes. When producing products of different specifications, only simple adjustments to the operating parameters of the displacement mechanism in the control system are typically required, eliminating the need for complex mechanical modifications to the equipment and significantly shortening product changeover time.

[0017] 2. Through the design of the moving component and the combination of the moving component and the locking caster wheels, this device can be quickly transferred to different workstations in the production workshop. The 360° turning characteristic of the caster wheels ensures that the device can still flexibly adjust its position in narrow spaces or complex layouts, while the locking function can fix the device during operation to prevent displacement caused by vibration or external force, thus ensuring the stability of operation.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 As shown, a quick demolding auxiliary device for an artificial stone press includes a press body 1, a stone slab 2 on the inner surface of the press body 1, an adsorption mechanism 3 at each of the four corners of the top of the stone slab 2, a telescopic adjustment mechanism 4 installed on the opposite sides of the adsorption mechanisms 3, a front-to-back displacement mechanism 5 installed at the opposite ends of the telescopic adjustment mechanisms 4, a vertical displacement mechanism 6 installed at the rear end of the front-to-back displacement mechanism 5, and a drive assembly 7 installed at the bottom of the vertical displacement mechanism 6.

[0026] In this embodiment, the entire device is moved to the predetermined position of the press body 1 by means of the locking casters 9 at the bottom. After reaching the position, the locking casters 9 are locked to ensure that the device remains stable during operation and will not be displaced due to vibration or external force.

[0027] Using the adsorption mechanisms 3 distributed at the four corners of the top of the stone slab 2, the adsorption mechanisms 3 generate a strong adsorption force, thereby firmly grasping the upper surface of the stone slab 2. After firmly grasping the stone slab 2, the device simulates and optimizes the motion trajectory of manual demolding through the precise coordination of the front and rear displacement mechanism 5 and the up and down displacement mechanism 6. Its motion trajectory is "first pull vertically upward, then move horizontally backward", thereby demolding the stone slab 2. The design of the telescopic adjustment mechanism 4 makes the spacing between adsorption points adjustable, allowing this device to quickly adapt to the production needs of artificial stone slabs of different specifications and shapes.

[0028] For details, please refer to Figure 1 and Figure 3 In this embodiment, each of the adsorption mechanisms 3 includes a negative pressure suction cup assembly 301, a negative pressure pump 302 is installed on the top of each of the negative pressure suction cup assemblies 301, and an mounting plate 303 is installed on the upper side of the outer surface of the negative pressure suction cup assembly 301.

[0029] After the demolding device is moved to the work station and adjusted through various mechanisms, the adsorption mechanism 3 of the entire device is aligned with the four corners of the top of the stone slab 2. The negative pressure pump 302 is started, and the gas is drawn out through the connecting pipe of the negative pressure suction cup assembly 301, so that a negative pressure state is formed inside. The suction cup body of the negative pressure suction cup assembly 301 is tightly attached to the surface of the stone slab 2, and under the action of atmospheric pressure, the stone slab 2 is firmly adsorbed.

[0030] Further reference Figure 1 and Figure 3 In this embodiment, each of the telescopic adjustment mechanisms 4 includes two mounting seats 401, and the electric telescopic rod assembly 402 is installed on the opposite sides of the two mounting seats 401 located on the same side.

[0031] Further reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the front and rear displacement mechanism 5 includes a mounting frustum 501, a fixed bracket 502 is mounted on the top of the mounting frustum 501, and a hydraulic telescopic cylinder 503 is mounted on the rear end of the fixed bracket 502. Two mounting seats 401 on the same side are respectively mounted to the mounting frame plate 303 and the mounting frustum 501.

[0032] After the stone slab 2 is completely removed from the mold, the hydraulic telescopic cylinder 503 of the front and rear displacement mechanism 5 is activated. The piston rod of the hydraulic telescopic cylinder 503 retracts backward, driving the stone slab 2, the adsorption mechanism 3 and the telescopic adjustment mechanism 4 to slide horizontally backward. This action will smoothly remove the stone slab 2, which has been removed from the mold, from the inside of the press body 1, making it convenient for the subsequent robotic arm or conveyor belt to grab and transfer it.

[0033] Further reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the vertical displacement mechanism 6 includes a limiting slide 601, and a movable seat 602 is provided on the inner surface of the limiting slide 601. The movable seat 602 is installed at the rear end of the hydraulic telescopic cylinder 503, and a threaded rod 603 is threadedly connected to the inner surface of the movable seat 602.

[0034] Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, the drive assembly 7 includes a rotating shaft 701, which is mounted on the bottom of the threaded rod 603. A bevel gear set 702 is mounted on the bottom of the rotating shaft 701. A transmission shaft 703 is mounted on the left end of the bevel gear set 702, and a drive motor 704 is mounted on the left end of the transmission shaft 703.

[0035] After the stone slab 2 is adsorbed and fixed by the adsorption mechanism 3, the drive motor 704 of the drive assembly 7 is started. The drive motor 704 transmits power and reverses through the transmission shaft 703 and the bevel gear set 702, driving the rotating shaft 701 and its connected threaded rod 603 to rotate at high speed. The threaded rod 603 and the movable seat 602 in the up and down displacement mechanism 6 form a screw and nut transmission pair. Since the movable seat 602 is limited in the limiting slide 601 and cannot rotate, the rotational motion of the threaded rod 603 will be converted into the vertical linear motion of the movable seat 602.

[0036] The movable seat 602 drives the hydraulic telescopic cylinder 503, fixed bracket 502, mounting platform 501, and all telescopic adjustment mechanisms 4 and adsorption mechanisms 3 installed on it to move upward together. At this time, the stone slab 2 is smoothly and vertically "pulled" out of the mold of the press body 1 by the four negative pressure suction cups, completing the most critical demolding action.

[0037] Through the designed adsorption mechanism 3, the adsorption mechanism 3 applies negative pressure to the stone slab 2. With the cooperation of the front and rear displacement mechanism 5 and the up and down displacement mechanism 6, the stone slab 2 can be pulled out of the press body 1, thereby achieving the effect of quickly demolding the stone slab 2. This reduces the safety risks such as being hit, scratched, or having muscle strains when workers use tools such as crowbars for demolding. Moreover, the adsorption mechanism adopts a matrix suction cup, and the adsorption area can be adjusted by the telescopic adjustment mechanism 4 to adapt to artificial stone slabs 2 of different sizes and even different shapes. When it is necessary to produce products of different specifications, it is usually only necessary to simply adjust the operating parameters of the displacement mechanism in the control system, without the need for complex mechanical modifications to the equipment, which greatly shortens the product changeover time.

[0038] Example 2: Based on Example 1, this example adds a movable component 8 and a locking caster wheel 9 for convenient movement of the demolding auxiliary device. By setting the movable component 8 and the locking caster wheel 9, the device can be quickly transferred to different workstations in the production workshop.

[0039] For details, please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, a movable component 8 is installed at the bottom of the drive component 7, and a lockable universal wheel 9 is installed at each of the four corners of the bottom of the movable component 8.

[0040] Further reference Figure 1 , Figure 2 and Figure 4 In this embodiment, the moving component 8 includes a base plate 801, and protective inclined blocks 802 are symmetrically installed on the top of the base plate 801. The two protective inclined blocks 802 are respectively installed on the front and rear sides of the bottom of the limiting slide block 601. The bottom of the drive motor 704 is installed on the left side of the top of the base plate 801. A handle 803 is installed on the right side of the top of the base plate 801 near the protective inclined blocks 802. Several locking universal wheels 9 are respectively installed at the four corners of the bottom of the base plate 801.

[0041] When the stone slab 2 is moved to the designated position and material needs to be released, the control system shuts down the negative pressure pump 302, so that the internal pressure of the negative pressure suction cup assembly 301 returns to normal pressure, the stone slab 2 is safely released, the drive motor 704 and the hydraulic telescopic cylinder 503 move in opposite directions, respectively driving the adsorption mechanism 3 and the telescopic adjustment mechanism 4 back to the initial position, preparing for the next demolding cycle.

[0042] The design of the movable component 8, combined with the locking caster wheel 9, enables the device to be quickly moved to different workstations in the production workshop. The 360° steering characteristic of the caster wheel ensures that the device can still be flexibly adjusted in narrow spaces or complex layouts, while the locking function can fix the device during operation, preventing displacement due to vibration or external force and ensuring the stability of operation.

[0043] The press body (1) in this solution can be an existing artificial stone press; used to press stone slabs into shape;

[0044] The negative pressure suction cup assembly 301 in this solution includes a suction cup body, connecting pipes, and an external control system as in the prior art. When in use, the negative pressure suction cup assembly 301 achieves stable gripping and release of the stone slab by means of the coordinated action of the suction cup body, connecting pipes, negative pressure pump 302, and control system, using the principle of negative pressure adsorption. It has a simple structure, is easy to operate, and does not damage the surface of the stone slab. It is widely used in the handling and processing of artificial stone and other slabs.

[0045] The electric telescopic rod assembly 402 in this solution includes a spring and an electric telescopic rod as in the prior art. The electric telescopic rod is installed inside the spring, which can enable the spring to extend and retract in a straight line during extension and retraction, thus avoiding the spring from becoming skewed.

[0046] The locking caster wheel 9 in this solution can be a self-locking caster wheel in the prior art. It controls the locking pin or slot through its own spring, lever or electromagnetic device. When the wheel is subjected to a force in a specific direction, the locking mechanism is triggered, fixing the part of the wheel in contact with the ground and preventing rotation or slippage. The bearing of the caster wheel allows the wheel to rotate 360°, but in the locked state, the locking mechanism will restrict the rotational freedom of the bearing, so that the wheel can only maintain the current direction.

[0047] Since the above are all very mature products in the prior art, they will not be described in detail in this application.

[0048] It should be noted that the specific installation method, circuit connection method, and control method of the negative pressure pump 302 and drive motor 704 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
