Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fiber cement board production equipment, and in particular to a press machine. Background Technology
[0002] Currently, in the production equipment for calcium silicate boards both domestically and internationally, some production lines use presses to press two stacks of slabs at a time to improve production efficiency. However, to press two stacks of slabs simultaneously, two additional cranes and matching stack conveying equipment are typically required before and after the press. Before entering the press, one stack of slabs is lifted by a crane, and the next stack is placed on top of it. After the press finishes pressing, when both stacks arrive at the second crane, the upper stack is lifted, allowing the lower stack to move first, and then the upper stack is lowered. While this method results in a shorter production time compared to pressing a single stack, it adds two pieces of equipment, increases costs, increases potential points of failure for later maintenance, and requires a larger floor space. Utility Model Content
[0003] The main purpose of this utility model is to propose a press equipment that aims to solve the problems of high cost and large footprint when pressing two stacks of slabs simultaneously in existing press production lines.
[0004] To achieve the above objectives, this utility model proposes a press device, including a frame, a working platform, a pressing mechanism, and a lifting mechanism. The working platform and the pressing mechanism are arranged opposite to each other on the frame in the z-direction. The pressing mechanism includes a pressing part that can cooperate with the working platform to press the stacked slab blanks. The pressing part is movable in the z-direction and located directly above the working platform. The lifting mechanism includes a lifting component for lifting the stacked slab blanks. The lifting component is movable in the z-direction.
[0005] According to some embodiments of the present invention, there are two lifting components, which are arranged opposite each other in the x-direction and move synchronously in the z-direction.
[0006] According to some embodiments of the present invention, the lifting assembly includes at least two lifting parts, which are spaced apart in the y-direction.
[0007] According to some embodiments of the present invention, the lifting mechanism further includes four slide rails arranged opposite each other on the frame in the x direction, all four slide rails extending in the z direction, and the lifting assembly further includes movable seats, with both ends of each movable seat movably disposed on the corresponding two slide rails in the z direction, and the two lifting parts being installed at intervals on the movable seats in the y direction.
[0008] According to some embodiments of the present invention, the lifting part includes a support section, which is mounted on the movable seat and has a support surface that can support the stacked slab blanks.
[0009] According to some embodiments of the present invention, the pressing mechanism further includes a pressing cylinder for driving the pressing part to move in the z direction, and the lifting mechanism further includes at least two lifting cylinders, the telescopic end of each lifting cylinder being connected to the corresponding lifting component.
[0010] According to some embodiments of the present invention, the lifting mechanism further includes a hydraulic synchronous motor for controlling the hydraulic pressure to move the telescopic ends of the two lifting cylinders synchronously.
[0011] According to some embodiments of this utility model, it also includes at least four position switches spaced apart on the frame in the z-direction. The four position switches and the two lifting cylinders are all electrically connected to the controller. The four position switches are arranged from top to bottom as follows: one corresponds to the lifting component being raised to the top position, one corresponds to the lifting component being loaded with stacked slabs at the upper limit position, one corresponds to the lifting component being transported to the lowering position above another stacked slab, and one corresponds to the lifting component being lowered to the bottom position.
[0012] According to some embodiments of the present invention, it further includes at least two conveying mechanisms, which are respectively disposed on both sides of the working platform in the x direction, and each conveying mechanism extends along the material feeding direction of the stacked slab blank.

[0014] This utility model has at least the following beneficial effects:
[0015] In this invention, the first stack of slabs is first conveyed to the working platform. The lifting component of the lifting mechanism moves upward to lift the first stack of slabs. Then, the second stack of slabs is conveyed to the working platform, and the lifting component moves downward to lower the first stack of slabs, placing it on top of the second stack. The pressing part of the pressing mechanism then moves downward and cooperates with the working platform to press the two stacks of slabs. After pressing, the lifting component moves upward to lift the first stack of slabs. After the second stack of slabs is output, the lifting component moves downward to lower the first stack of slabs back onto the working platform for output. This invention integrates the function of lifting stacks of slabs using a crane into the press equipment, eliminating the need for two separate cranes on the incoming and outgoing sides of the press. This reduces costs and the footprint of the press equipment, while also reducing potential maintenance points. Attached Figure Description

[0027] This utility model provides a press device. Figures 1 to 4 This invention provides a specific embodiment of a press device.
[0028] like Figure 1 As shown, this utility model embodiment provides a press device 100, including a frame 1, a working platform 2, a pressing mechanism 3, and a lifting mechanism 4. The working platform 2 and the pressing mechanism 3 are arranged opposite to each other on the frame 1 in the z-direction. The pressing mechanism 3 includes a pressing part 31 that can cooperate with the working platform 2 to press the stacked blanks 200. The pressing part 31 is movable in the z-direction and is located directly above the working platform 2. The lifting mechanism 4 includes a lifting component 41 for lifting the stacked blanks 200. The lifting component 41 is movable in the z-direction.
[0029] In this invention, the first stack of slabs is first transported to the working platform 2. The lifting component 41 of the lifting mechanism 4 moves upward to lift the first stack of slabs. Then, the second stack of slabs is transported to the working platform 2. The lifting component 41 moves downward to lower the first stack of slabs, placing the first stack of slabs on top of the second stack. Then, the pressing part 31 of the pressing mechanism 3 moves downward and cooperates with the working platform 2 to press the two stacks of slabs 200. After pressing, the lifting component 41 moves upward to lift the first stack of slabs. After the second stack of slabs is output, the lifting component 41 moves downward to lower the first stack of slabs onto the working platform 2 for output. This invention integrates the function of lifting the stack of slabs 200 by a crane into the press equipment 100, eliminating the need for two additional cranes on the incoming and outgoing sides of the press. This reduces costs and the footprint of the press equipment 100, while also reducing potential maintenance points.
[0030] It should be noted that, as Figure 5 As shown, the stack of slab blanks 200 includes a slab body 210 and a pad 220, the bottom area of which is larger than the bottom area of the slab body 210. The lifting component 41 only contacts the pad 220. When the lifting component 41 moves downward, causing the first stack of slab blanks to descend and be placed on the second stack of slab blanks, the lifting component 41 will continue to move downward a certain distance, positioned between the pads 220 of the first stack of slab blanks and the pads 220 of the second stack of slab blanks. This prevents the pressure from the pressing part 31 pressing the stack of slab blanks 200 from being transmitted to the lifting component 41, which could damage the lifting component 41.
[0031] The number of lifting components 41 is not limited, as long as the lifting components 41 can drive the stack of blanks 200 to rise and fall. For example, in some embodiments, such as... Figure 1 As shown, two lifting components 41 are provided, arranged opposite each other in the x-direction and moving synchronously in the z-direction. This arrangement, with the two lifting components 41 working together to fix the pad 220 of the stack blank 200, and then moving the two lifting components 41 in the z-direction to lift and lower the stack blank 200, avoids the other side of the pad 220 scraping against the inner wall of the frame 1 during the lifting and lowering of the stack blank 200, and also provides a more secure fixation of the pad 220. Simultaneously, the synchronous movement of the two lifting components 41 prevents the stack blank 200 from tilting in the x-direction during lifting and lowering.
[0032] Furthermore, in some embodiments, such as Figure 1As shown, the lifting assembly 41 includes at least two lifting parts 411, which are spaced apart in the y-direction. The four lifting parts 411 of the two lifting assemblies 41 cooperate to fix the pad 220 of the stacked blank 200, thereby improving the stability of the stacked blank 200 during lifting.
[0033] To prevent the stacked slabs 200 from tilting in the y-direction during lifting and lowering, as follows: Figure 1 and Figure 3 As shown, the lifting mechanism 4 further includes four slide rails 42 arranged in pairs opposite to each other on the frame 1 in the x-direction. All four slide rails 42 extend along the z-direction. The lifting assembly 41 also includes movable seats 412. The two ends of each movable seat 412 are movably mounted on the corresponding two slide rails 42 in the z-direction. The two lifting parts 411 are spaced apart on the movable seats 412 in the y-direction. Since the distance between the two slide rails 42 is fixed, and the length of the movable seats 412 is fixed, when the lifting assembly 41 moves in the z-direction, the two ends of the movable seats 412 move synchronously on the two slide rails 42, causing at least two lifting parts 411 spaced apart on the movable seats 412 to move synchronously, thereby preventing the stacked slab blank 200 from tilting in the y-direction during lifting.
[0034] In some embodiments, such as Figure 2 and Figure 4 As shown, the lifting part 411 includes a support section 4111, which is mounted on the movable seat 412. The support section 4111 has a support surface for supporting the stacked blank 200. Because the stacked blank 200 is relatively heavy, the friction between the pad 220 and the support surface is relatively large. Fixing the stacked blank 200 can be achieved simply by supporting it. Compared to clamping, this support method is not only more stable but also applicable to stacked blanks 200 of different sizes.
[0035] In some embodiments, such as Figure 1 and Figure 3 As shown, the pressing mechanism 3 further includes a pressing cylinder 32 for driving the pressing part 31 to move in the z-direction, and the lifting mechanism 4 further includes at least two lifting cylinders 43, the telescopic end of each lifting cylinder 43 being connected to the corresponding lifting assembly 41. With this configuration, the pressing cylinder 32 and the lifting cylinder 43 can share a hydraulic system, reducing driving components, lowering production costs, and reducing potential points of failure for later maintenance.
[0036] Specifically, there are four lifting cylinders 43, and the four lifting cylinders 43 are respectively connected to the two ends of the two movable seats 412.
[0037] Furthermore, in some embodiments, such as Figure 1 As shown, the lifting mechanism 4 also includes a hydraulic synchronous motor 44 for controlling the hydraulic pressure to move the extension and retraction ends of the two lifting cylinders 43 synchronously. By controlling the hydraulic balance through the hydraulic synchronous motor 44, the extension and retraction ends of the two lifting cylinders 43 move synchronously, thus achieving synchronous movement of the two lifting components 41 in the z-direction. The hydraulic synchronous motor 44 is prior art, so its specific components will not be described in detail.
[0038] To prevent the lifting component 41 from moving excessively in the z-direction and colliding with the pressing part 31 of the pressing mechanism 3, in some embodiments, such as Figure 1 and Figure 2 As shown, the press equipment 100 also includes at least four position switches 5 spaced apart on the frame 1 in the z-direction. The four position switches 5 and the two lifting cylinders 43 are electrically connected to the controller. From top to bottom, the four position switches 5 are configured as follows: one corresponding to the lifting assembly 41 at its top position; one corresponding to the lifting assembly 41 at its maximum lifting limit position when loading the stack of slabs 200; one corresponding to the lifting assembly 41 at its lowering position when transporting the stack of slabs 200 above another stack of slabs 200; and one corresponding to the lifting assembly 41 at its bottom position. When the lifting assembly 41 moves to the position corresponding to each of the position switches 5, the position switch 5 sends a signal to the controller, which then controls each of the lifting cylinders 43 to stop operating, thereby preventing the lifting assembly 41 from moving excessively in the z-direction.
[0039] In some embodiments, such as Figure 1 As shown, the press equipment 100 also includes at least two conveying mechanisms 6, which are respectively arranged on both sides of the working platform 2 in the x-direction. Each conveying mechanism 6 extends along the material feeding direction of the stacked slab blank 200. With this arrangement, the stacked slab blank 200 is conveyed from the previous process to the working platform 2 via the conveying mechanisms 6. After the pressing mechanism 3 completes the pressing of the stacked slab blank 200, it is then conveyed to the next process, thereby achieving automated production of the stacked slab blank 200, reducing labor costs, and improving production efficiency. Specifically, the conveying mechanism 6 includes a conveyor belt.
[0040] To prevent the pad 220 of the stacked slab 200 from pressing against the conveying mechanism 6 when the pressing mechanism 3 presses down on the stacked slab 200, in some embodiments, such as... Figure 1 and Figure 3As shown, the press equipment 100 also includes two hydraulic cylinders 7 for driving the conveying mechanism 6 to move in the z-direction, each hydraulic cylinder 7 being drivenly connected to the corresponding conveying mechanism 6. With this configuration, when the stacked slab blank 200 needs to be conveyed, the hydraulic cylinder 7 drives the conveying mechanism 6 to rise above the working platform 2; when the pressing mechanism 3 presses down on the stacked slab blank 200, the hydraulic cylinder 7 drives the conveying mechanism 6 to descend below the working platform 2, preventing the pad 220 of the stacked slab blank 200 from pressing against the conveying mechanism 6.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
