Description

Technical Field

[0001] This invention relates to the field of engineered wood panel manufacturing technology, and specifically discloses a rapid feeding device for a multi-layer hot press. Background Technology

[0002] In the production and processing of medium-density fiberboard (MDF), the pre-pressed blanks are cut and then sent to a hot press for hot pressing. The high temperature and pressure of the hot press allow the adhesive to fully penetrate between the fibers, forming strong chemical bonds and improving the strength and stability of the board. In the industry, to improve the hot pressing efficiency of MDF, multi-layer hot presses are typically used to process a dozen or more blanks at a time. However, when using multi-layer hot presses, limitations in the feeding device mean that the blanks must be manually pushed into the gaps between the hot press plates layer by layer. This process is not only time-consuming and labor-intensive but also poses safety hazards.

[0003] The invention patent with application number 201510497756.6 discloses an automatic loading and unloading system for a multi-layer hot press, including a control system and an automatic loading and unloading device. The automatic loading and unloading device includes a loading lifting platform, a sheet material transfer device, and an unloading lifting platform arranged sequentially at intervals along a straight line. A multi-layer hot press is arranged between the sheet material transfer device and the unloading lifting platform. The sheet material transfer device includes a frame, a suction cup manipulator, and loading and unloading trays. The frame includes a tray lifting mechanism. The loading and unloading tray includes a tray base and a loading and unloading push rod mechanism arranged thereon. The suction cup manipulator is fixed on the loading and unloading tray or the tray lifting mechanism. While the automatic loading and unloading device disclosed in this invention achieves automatic loading and unloading of slabs in a multi-layer hot press, its operation relies on the lifting of the platform layer by layer, combined with the gripping action of the suction cup robotic arm. This allows for only layer-by-layer loading of slabs, which can range from a dozen to thirty sheets in a multi-layer hot press. This results in low loading efficiency and significant heat loss during the long loading intervals, leading to substantial energy consumption for the entire multi-layer hot press. Therefore, to address the aforementioned shortcomings of existing automatic loading and unloading devices in multi-layer hot press systems, this application proposes a rapid loading device for multi-layer hot presses that can quickly load all slabs into the hot press in one go. This improves the hot pressing efficiency of the multi-layer hot press, reduces heat loss during loading and unloading, and lowers the energy consumption of hot pressing. Summary of the Invention

[0004] The present invention aims to provide a rapid feeding device for a multi-layer hot press, so as to realize the rapid loading of all slabs into the hot press in one go, thereby improving the hot pressing efficiency of the multi-layer hot press, reducing heat loss during the loading and unloading process, and reducing the power consumption of hot pressing of the slabs.

[0005] This invention is achieved through the following technical solution:

[0006] A rapid feeding device for a multi-layer hot press includes a conveying unit, a flipping unit connected to the tail end of the conveying unit, and a feeding unit provided on the side end of the flipping unit.

[0007] The flipping unit includes a fixed upright plate, on which a rotating drum is rotatably mounted. One end of the rotating drum is connected to a power source. Multiple radially arranged partitions are evenly arranged on the outer surface of the rotating drum. A support strip is rotatably connected to the lower end of the partition near the feeding unit. A guide block is provided on the partition below the support strip. A push rod passes through the guide block, and an elastic element is connected between the push rod and the guide block. A connecting strip is provided between one end of the push rod and the support strip, and a pressing wheel extending out of the partition is provided at the other end. A track ring is installed on the upright plate, which is concentrically arranged with the rotating drum and interacts with the pressing wheel. A protruding guide part is provided on the top of the track ring.

[0008] The feeding unit includes a fixed U-shaped seat, a flipping seat rotatably mounted at one end of the U-shaped seat, and a driving component for driving the flipping seat to rotate on the U-shaped seat. A movable plate is slidably mounted in the flipping seat, and a second rack is mounted on the lower surface of the movable plate. A rotating rod is mounted in the U-shaped seat, and a second gear meshing with the second rack is mounted on the rotating rod. A transmission component is mounted between the rotating rod and the drum. A row of equally spaced spacers and a pushing mechanism are mounted on the upper surface of the movable plate.

[0009] This invention discloses a rapid feeding device for a multi-layer hot press, which allows for the simultaneous feeding of the next batch of fiberboard blanks while the hot press is hot-pressing them. Specifically, the feeding process involves a conveying unit transporting the blanks one by one to a feeding unit. During operation, the feeding unit is driven by a power source to rotate a drum at a set speed, thus loading the blanks one by one between adjacent partitions. During rotation, the lower end of the blank is supported by a support strip. When the blank rotates to a vertical position, the action between the extrusion roller and the protruding guide causes the push rod to move towards the connecting strip. The connecting strip then causes the support strip to rotate towards the feeding unit. When the support strip rotates to a certain angle, the blank slides down from the support strip and falls into the gap between the two partitions. As the support strip rotates closer to vertical, the tilted blank, due to the change in its center of gravity, stands directly on the moving plate between the two partitions. Simultaneously, the action between the transmission assembly, the second gear, and the second rack causes the moving plate to gradually move towards one side of the multi-layer hot press, thus allowing the blanks to stand one by one in the gaps between the partitions on the moving plate. Once the number of slabs loaded onto the moving plate reaches the set value, the operation of the flipping unit is paused. Then, the drive assembly causes the entire flipping seat to rotate along with the slabs toward the multi-layer hot press until the flipping seat rotates to a vertical position. At this point, each slab is aligned with the gap between the hot press plates in the multi-layer hot press. After alignment, the pushing mechanism is started to push all the slabs into the hot press gap simultaneously. During the process of pushing the slabs in, the slabs from the previous batch will be pushed out. Then, the multi-layer hot press will simultaneously perform hot pressing on all the slabs.

[0010] As a further provision of the above solution, the drive assembly includes a first telescopic device, the end of which is connected to a first rack. The tilting seat is rotatably connected to a U-shaped seat via a pin, and the outer end of the pin is connected to a first gear that meshes with the first rack. This is one specific design scheme for the drive assembly. By pushing the first rack with the first telescopic device, and then through the meshing transmission between the first rack and the first gear, the tilting seat connected to the pin can be rotated from a horizontal state to a vertical state.

[0011] As a further provision of the above scheme, the transmission assembly includes a connecting shaft connected to the drum. A driving wheel is located at the end of the connecting shaft, and a driven wheel is located at the end of the rotating rod. A transmission component is provided between the driving wheel and the driven wheel. The above is one specific design scheme for the transmission assembly. Through a reasonable transmission ratio design, the moving plate can move a set distance linearly for each rotation of the drum by a certain angle, thereby allowing the blanks on the flipping unit to be loaded one by one between adjacent spacers.

[0012] As a further feature of the above scheme, the driven wheel is connected to the rotating rod via a one-way transmission device. A second telescopic device is provided at the end of the U-shaped seat, and an electromagnet is connected to the end of the second telescopic device. A magnetic block aligned with the electromagnet is provided on the moving plate. The above is a specific design scheme for the moving plate reset structure. After all the blanks on the moving plate are loaded into the hot press and rotated to a horizontal position for reset, the moving plate is reset by magnetic attraction and the pull-back action of the second telescopic device. Furthermore, due to the design of the one-way transmission device, the drum will not rotate synchronously in the opposite direction during the reset process.

[0013] As a further feature of the above design, the moving plate has two rows of spacers arranged front and back, and the gap between two adjacent spacers is aligned with the topmost partition on the drum. This design of two rows of spacers ensures that the slab unloaded from the flipping unit can stand stably on the moving plate.

[0014] As a further provision of the above solution, the pushing mechanism includes a strip-shaped receiving groove formed on the upper surface of the moving plate. A bidirectional lead screw is rotatably mounted in the strip-shaped receiving groove, and one end of the bidirectional lead screw is connected to a lead screw motor. Both ends of the strip-shaped receiving groove are provided with screw-hole sliders that interact with the bidirectional lead screw. A supporting bar extending out of the strip-shaped receiving groove is connected to the screw-hole slider, and the ends of the two supporting bars are connected to a pushing bar. The above is one specific design scheme of the pushing mechanism. By driving the bidirectional lead screw to rotate through the lead screw motor, the two screw-hole sliders are brought closer together. During the process of the two screw-hole sliders approaching each other, the supporting bar can move the pushing bar towards one side of the multi-layer hot press, thereby simultaneously pushing all the slabs mounted on the moving plate into the multi-layer hot press.

[0015] As a further feature of the above solution, linear slide rails are fixed on both opposite sides of the flipping base, and the moving plate is slidably connected to the two linear slide rails. The design of the linear slide rails ensures stable linear movement of the moving plate within the flipping base.

[0016] As a further feature of the above scheme, elastic limiting plates are connected to the lower ends of the opposite sides of two adjacent spacers. The upper ends of the two elastic limiting plates are open, and the lower ends are straight and narrow. The design of the elastic limiting plates ensures that the slab unloaded from the flipping unit can be stably limited in the gap between the two adjacent spacers, and ensures the stability of the slab during the subsequent rotation of the flipping seat.

[0017] As a further feature of the above scheme, a rotating rod is rotatably connected to the side of the U-shaped seat away from the flipping unit. Strips are connected to both ends of the rotating rod, and a correction push plate is connected to the ends of the two strips. A hydraulic telescopic rod is connected to the rotating rod to achieve its own rotation adjustment. With this structural design, after all the slabs are loaded into the feeding unit, the hydraulic telescopic rod can move the correction push plate towards the side of a row of slabs, thereby aligning the row of slabs and allowing them to be neatly pushed into the hot press for hot pressing.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The multi-layer hot press rapid feeding device disclosed in this invention receives pre-pressed and cut slabs through a conveying unit, then transfers them to a flipping unit. The flipping unit then transfers the slabs one by one to the feeding unit, where they are spaced upright. The feeding unit then rotates the slabs to a vertical position, aligning all slabs with the hot pressing gaps in the multi-layer hot press. Finally, all slabs are pushed into the hot pressing gaps all at once. This rapid feeding device achieves a streamlined receiving process for slabs in the fiberboard production line, allowing them to be pushed into the multi-layer hot press for processing all at once. It eliminates the need for intermediate stacking and layer-by-layer feeding of slabs, simplifying the entire fiberboard production line and effectively improving the feeding efficiency of the multi-layer hot press while reducing heat loss on the hot pressing plates during loading and unloading.

[0020] The flipping unit in this invention is an improved design based on a flip-plate cooler. While simultaneously conveying multiple slabs, the flipping unit, through the design of push rods, extrusion rollers, connecting strips, support strips, and track rings, allows the slabs, when rotated and conveyed to a vertical position, to directly enter the feeding unit from the side. Simultaneously, the moving plate in the feeding unit synchronizes with the flipping action of the drum, ensuring that the slabs unloaded from the flipping unit stand upright between the spacers, thus enabling the rows of slabs to precisely align with the hot pressing gaps of the multi-layer hot press after flipping. The entire flipping unit's structural design is novel and ingenious, and in conjunction with the feeding unit, it neatly arranges the slabs pushed into the multi-layer hot press layer by layer, allowing them to be pushed into the multi-layer hot press for processing in one go, resulting in excellent performance.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-10 This application will be described in detail with reference to the embodiments. Example 1

[0034] Example 1 discloses a rapid feeding device for a multi-layer hot press, as shown in the attached figure. Figure 1 and attached Figure 2The system includes a conveying unit 2 mounted on the ground 1, a flipping unit 3 connected to the right side of the conveying unit 2, a feeding unit 4 in front of the flipping unit 3, and a multi-layer hot press (not shown in the figure) located to the right of the feeding unit 4. Additionally, a control cabinet 5 for controlling the entire feeding device is located to the left of the feeding unit 4. During operation, the pre-pressed and cut fiberboard is received by the conveying unit 2 and then fed to the flipping unit 3. The flipping unit 3 flips the fiberboard from a horizontal to a vertical position and pushes it into the feeding unit 4 in the vertical position. When the fiberboard in the feeding unit 4 has received a set number of pieces, they are all erected and then simultaneously pushed into the gap between the hot plates of the multi-layer hot press.

[0035] Conveying unit 2 uses a conventional roller conveyor and connects to the tail end of the fiberboard pre-pressing and cutting production line. (See attached reference.) Figure 3 and attached Figure 4 The flipping unit 3 includes a rotating drum 301 and a vertical plate 302. The vertical plate 302 is fixed on the ground 1. The roller shaft on the rotating drum 301 is rotatably connected to the vertical plate 302, and a power source 303 for driving the rotating drum 301 to rotate is provided on the vertical plate 302. A plurality of partitions 304 are evenly arranged circumferentially on the outer circumferential surface of the rotating drum 301. The partitions 304 are arranged radially, and the partition 304 at the middle horizontal position of the left end of the rotating drum 301 is flush with the conveying roller on the conveying unit 2. At the same time, an arc-shaped groove is provided on the ground 1 to allow the lower partition 304 to rotate smoothly.

[0036] Reference Appendix Figure 10 A guide block 305 is provided at the lower end of the partition 304, through which a horizontally arranged push rod 306 passes. An elastic element 307, which can be a spring, connects the push rod 306 and the guide block 305. A support strip 308 is rotatably connected to the side of the partition 304 above the push rod 306, and the rotatable connection between the support strip 308 and the partition 304 is located on the side near the feeding unit 4. A connecting strip 309 is rotatably connected between the support strip 308 and the end of the push rod 306. The other end of the push rod 306 extends out of the side of the partition 304, and an extrusion wheel 310 is rotatably connected to its outer end. A track ring 311 that interacts with the extrusion wheel 310 is concentrically fixed on the side of the upright plate 302 facing the drum 301, and a protruding guide portion 312 extending toward the drum 301 is provided on the top of the track ring 311. When the extrusion roller 310 rotates to interact with the protruding guide part 312, the push rod 306 can overcome the force of the elastic element 307 and move to the side of the feeding unit 4. Then, through the action of the connecting strip 309, the support strip 308 will rotate towards the side of the feeding unit 4, thereby causing the fiberboard supported on the support strip 308 to rotate.

[0037] Reference Appendix Figures 5-8 The feeding unit 4 includes a base box 401, with a U-shaped seat 402 fixed to the upper end of the base box 401. A tilting seat 403 is provided in the U-shaped seat 402, and the end of the tilting seat 403 near the multi-layer hot press is rotatably connected to the U-shaped seat 402 via a pin. A first gear 400 is connected to the outer end of the pin extending out of the U-shaped seat 402. A first telescopic device 404 is fixedly installed on the U-shaped seat 402. The telescopic end of the first telescopic device 404 is connected to a first rack 405 that meshes with the first gear 400, so that the tilting seat 403 can be rotated and adjusted between horizontal and vertical states under the push of the first telescopic device 404 and the meshing of the gear and rack.

[0038] Linear slide rails 406 are fixed on the front and rear opposite sides of the flipping base 403. A movable plate 407 is provided between the two linear slide rails 406, and spacer strips 408 are provided at equal intervals in rows at both ends of the upper surface of the movable plate 407, so that fiberboard removed from the flipping unit 3 can be placed between two adjacent spacer strips 408. A second rack 426 is provided on the lower surface of the movable plate 407, parallel to the linear slide rails 406. A rotating rod 427 is rotatably provided in the U-shaped base 402, perpendicular to the second rack 426. A second gear 428 is provided on the rotating rod 427, meshing with the second rack 426. The rotating rod 427 extends outward from the U-shaped seat 402 and is connected to a driven wheel 409 via a one-way transmission. A connecting shaft 410, penetrating the bottom box 401, is connected to the roller shaft of the drum 301. A driving wheel 411 is located at the end of the connecting shaft 410, and a transmission component 412 is positioned between the driven wheel 409 and the driving wheel 411. Specifically, the driven wheel 409 and the driving wheel 411 can be either sprockets or pulleys, and the transmission component 412 can be either a transmission chain or a transmission belt. Through this transmission design, the connecting shaft 410 rotates during the rotation of the drum 301, causing the rotating rod 427 to rotate synchronously. Then, through the meshing transmission between the second gear 428 and the second rack 426, the moving plate 407 moves progressively along the linear slide rail 406, allowing the fiberboard to be inserted one by one into the gap between two adjacent spacer bars 408.

[0039] A second telescopic device 413 is provided at the end of the U-shaped base 402 on the side away from the multi-layer hot press. An electromagnet 414 is connected to the end of the first telescopic device 413. A magnetic block 415 aligned linearly with the electromagnet 414 is fixed on the lower surface of the moving plate 407. When it is necessary to pull the moving plate 407 back to its initial state, current is passed through the electromagnet 414 so that the electromagnet 414 and the magnetic block 415 attract each other. Then, the second telescopic device 413 is retracted to move the moving plate 407 along the linear slide rail 406 to reset.

[0040] A strip-shaped storage groove parallel to the linear slide rail 406 is formed on the upper surface of the moving plate 407. A bidirectional lead screw 416 is rotatably mounted in the strip-shaped storage groove, and a lead screw motor 417 for driving the bidirectional lead screw 416 is provided on the lower surface of the moving plate 407. The lead screw motor 417 and the bidirectional lead screw 416 can be driven by bevel gears. Two screw-hole sliders 418 are symmetrically arranged at both ends of the strip-shaped storage groove and are screwed to both ends of the bidirectional lead screw 416. Then, a support bar 419 extending out of the strip-shaped storage groove is rotatably connected to the screw-hole slider 418, and the two support bars 419 are mirror-symmetrically arranged. Finally, a push bar 420 capable of simultaneously pushing all the fiberboards is connected to the movable ends of the two support bars 419.

[0041] In the operation of the multi-layer hot press rapid feeding device disclosed in Embodiment 1, the conveying unit 2 conveys the fiberboards one by one onto the flipping unit 3, ensuring that each fiberboard is positioned between two adjacent partitions 304. As the partitions 304 rotate from a horizontal to a vertical state, the bottom of the fiberboard is supported by the corresponding support strips 308. Simultaneously, due to the transmission action of components such as the transmission component 412, the second gear 428, and the second rack 426, the moving plate 407 moves horizontally along the linear slide rail 406.

[0042] When the gap between the two spacer bars 408 on the moving plate 407 is aligned with the partition 304 in the vertical state at the top, the push rod 306 will move towards the material unit 4 side due to the action between the extrusion wheel 310 and the protruding guide part 312. Then, through the action of the connecting bar 309, the support bar 308 will move towards the gap of the spacer bar 408. When the support bar 308 reaches a certain tilt angle, the fiberboard supported on the support bar 308 will slide into the gap of the spacer bar 408. Until the support bar 308 rotates to a near vertical state, the fiberboard that has slid into the gap of the spacer bar 408 will stand upright in the gap of the spacer bar due to the offset of the center of gravity.

[0043] After repeating the above actions multiple times, the moving plate 407 will move to the far end near the side of the multi-layer hot press, and a fiberboard will be installed in the gaps between all the spacers 408. Then the flipping unit 3 will pause operation and the first telescopic device 404 will be activated. Through the meshing transmission between the rack and pinion, the flipping seat 403 will rotate from a horizontal state to a vertical state. At this time, the multiple fiberboards will also be in a horizontal state with equal vertical spacing and aligned with the gaps between the hot press plates in the multi-layer hot press.

[0044] Once the gaps between multiple fiberboards and the multi-layer hot press plates are aligned, the lead screw motor 417 is activated to rotate the bidirectional lead screw 416. The bidirectional lead screw 416 then causes the two screw-hole sliders 418 to move closer together. The spreading bar 419 then moves the pushing bar 420 towards one side of the hot press, simultaneously pushing all the fiberboards into the gaps between the hot press plates. Finally, the entire feeding unit 4 is reset. After reset, the flipping unit 3 is activated to repeat the above actions. Example 2

[0045] Example 2 discloses a multi-layer hot press rapid feeding device that is further optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0046] Reference Appendix Figure 9 In this embodiment 2, on the one hand, elastic limiting plates 421 are connected to the lower ends of the opposite sides of two adjacent spacers 408, and the two elastic limiting plates 421 are arranged in a mirror symmetrical manner, with an open design at the upper end and a straight constricted design at the lower end. This allows the flipping unit 3 to pass through the gap between the elastic limiting plates 421 when placing the fiberboard between the two spacers 408, and to use the elastic force of the elastic limiting plates 421 to hold the fiberboard in the center. This prevents the fiberboard from tilting during the flipping process of the flipping seat 403 from a horizontal state to a vertical state, which would cause it to be unable to align with the hot pressing gap in the multilayer hot press.

[0047] Secondly, in this embodiment 2, a rotating rod 422 is rotatably connected to the side of the U-shaped seat 402 away from the flipping unit 3. Strips 423 are connected to both ends of the rotating rod 422, and a correction push plate 424 acting on the side of the fiberboard is connected to the ends of the two strips 423. Finally, a hydraulic telescopic rod 425 for driving the rotating rod 422 to rotate is provided on the U-shaped seat 402 or the base box 401. This allows the hydraulic telescopic rod 425 to be activated after all the fiberboards are sequentially placed between the spacers 408, causing the correction push plate 424 to rotate towards the side of a row of fiberboards, thereby aligning the row of fiberboards and ensuring that the fiberboards can be neatly pushed into the hot press for hot pressing.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
