Description

Technical Field

[0001] The invention relates to the technical field of artificial board preparation, and in particular discloses a multi-layer hot press rapid feeding device. Background Art

[0002] In the production and processing of medium-density fiberboard, the pre-pressed slabs need to be sent to the hot press for hot pressing after cutting. The high temperature and high pressure treatment of the hot press can allow the adhesive to fully penetrate between the fibers, forming a strong chemical bond, and improving the strength and stability of the board. In the industry, in order to improve the hot pressing efficiency of medium-density fiberboard, a multi-layer hot press is usually used to hot press a dozen slabs at a time. However, when using a multi-layer hot press to process the slabs, it is limited by the insufficiency of the feeding device, and the slabs need to be manually pushed into the hot pressing plate gap layer by layer, resulting in the loading process of the multi-layer hot press not only being time-consuming and labor-intensive, but also posing a safety hazard.

[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 plate transfer device and a unloading lifting platform arranged in sequence along a straight line. A multi-layer hot press is arranged between the plate transfer device and the unloading lifting platform. The plate transfer device includes a frame, a suction cup manipulator and a loading and unloading tray. 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. Although the automatic loading and unloading device disclosed in the invention realizes the automatic loading and unloading of the slabs in the multi-layer hot press, during the operation of the device, the lifting and lowering of the lifting platform layer by layer, combined with the grasping action of the suction cup type manipulator, can only realize the loading of the slabs layer by layer, and the number of slabs in the multi-layer hot press ranges from a dozen to thirty, resulting in low loading efficiency of the entire slab, and in the long time interval of loading, the heat loss in the hot pressing plate is serious, resulting in a large power loss of the entire multi-layer hot press. Therefore, in view of the above-mentioned deficiencies of the automatic loading and unloading device in the existing automatic loading and unloading system of the multi-layer hot press, the present application proposes a multi-layer hot press fast loading device that can quickly load all the slabs into the hot press at one time, so as to improve the hot pressing efficiency of the multi-layer hot press, reduce the heat loss during the loading and unloading process, and reduce the power loss of the hot pressing forming of the plate. Summary of the invention

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

[0005] The present invention is achieved through the following technical solutions: A multi-layer hot press rapid feeding device comprises a conveying unit, the tail end of the conveying unit is connected with a turning unit, and the side end of the turning unit is provided with a feeding unit; The flip unit comprises a fixed vertical plate, a rotating drum is rotatably arranged on the vertical plate, and one end of the rotating drum is connected to a power source, a plurality of radially arranged partitions are evenly arranged on the outer circumferential surface of the rotating drum, a supporting bar is rotatably connected to the lower end of the partition close to the side of the feeding unit, a guide block is arranged on the partition below the supporting bar, a pushing rod passes through the guide block, and an elastic member is connected between the pushing rod and the guide block, a connecting bar is arranged between one end of the pushing rod and the supporting bar, and an extrusion wheel extending out of the partition is arranged at the other end, a track ring which is concentrically arranged with the rotating drum and acts on the extrusion wheel is installed on the vertical plate, and a raised guide portion is arranged on the top of the track ring; The loading unit includes a fixed U-shaped seat, a flip seat is rotatably provided at one end of the U-shaped seat, and a driving assembly for driving the flip seat to rotate is provided on the U-shaped seat, a movable plate is provided for limited sliding in the flip seat, and a second rack is provided on the lower surface of the movable plate, a rotating rod is provided in the U-shaped seat, a second gear meshing with the second rack is provided on the rotating rod, a transmission assembly is provided between the rotating rod and the rotating drum, and rows of equally spaced spacing bars and a pushing mechanism are provided on the upper surface of the movable plate.

[0006] The multi-layer hot press quick feeding device disclosed by the present invention starts to feed the next batch of slabs while the hot press is hot pressing the slabs of the fiberboard. The specific feeding process is that the conveying unit conveys the slabs to the feeding unit one by one, and the feeding unit is driven by the power source to rotate the drum at a set speed during operation, so that the slabs are loaded one by one between two adjacent partitions, and the lower end of the slab is supported by the support bar during the rotation process. When the slab is rotated to a vertical state, the push rod moves to one side of the connecting bar due to the action between the extrusion wheel and the raised guide part, and then the support bar rotates toward the feeding unit through the action of the connecting bar. When the support bar rotates to a certain inclination angle, the slab will slide down from the support bar and fall into the gap between the two spacer bars, and when the support bar rotates to a vertical position, the inclined slab will stand directly on the moving plate between the two spacer bars due to the change of the center of gravity. At the same time, the action between the transmission assembly, the second gear and the second rack will make the moving plate gradually move toward one side of the multi-layer hot press, so that the slabs can be stood one by one in the gap between the spacer bars on the moving plate. When the number of slabs loaded on the movable plate reaches the set value, the operation of the flip unit is suspended, and then the driving component makes the entire flip seat carry the slabs and rotate toward the direction of the multi-layer hot press until the flip seat rotates to a vertical state. At this time, each slab is aligned with the gap between the hot pressing plates in the multi-layer hot press. After alignment, the pushing mechanism is started and all the slabs are pushed into the hot pressing gap at the same time. During the process of pushing the slabs in, the slabs of the previous batch will be ejected, and then all the slabs will be hot pressed by the multi-layer hot press at the same time.

[0007] As a further configuration of the above scheme, the driving assembly includes a first telescopic device, the end of the first telescopic device is connected to a first rack, the flip seat is rotatably connected to the U-shaped seat via a pin shaft, and the outer end of the pin shaft is connected to a first gear meshing with the first rack. The above is one of the specific design schemes of the driving assembly, the first rack is pushed by the first telescopic device, and the meshing transmission between the first rack and the first gear can make the flip seat connected to the pin shaft rotate and adjust from a horizontal state to a vertical state.

[0008] As a further configuration of the above scheme, the transmission assembly includes a connecting shaft connected to the rotating drum, a driving wheel is arranged at the end of the connecting shaft, a driven wheel is arranged at the end of the rotating rod, and a transmission member is arranged between the driving wheel and the driven wheel. The above is one of the specific design schemes of the transmission assembly. Through a reasonable transmission ratio design, each time the rotating drum rotates a certain angle, the moving plate can move a set distance in a straight line, so that the slabs on the flip unit can be loaded one by one between adjacent spacer bars.

[0009] As a further configuration of the above scheme, the driven wheel is connected to the rotating rod through a one-way transmission, a second telescopic device is provided at the end of the U-shaped seat, an electromagnet is connected to the end of the second telescopic device, and a magnetic block aligned with the electromagnet is provided on the movable plate. The above is a specific scheme design of the movable plate reset structure. When all the slabs on the movable plate are loaded into the hot press and rotated to a horizontal state and reset, the movable plate is moved and reset by the magnetic attraction force and the pullback action of the second telescopic device, and during the movement and reset process, due to the design of the one-way transmission, the drum will not rotate synchronously in the opposite direction.

[0010] As a further configuration of the above solution, the spacer bars on the movable plate are arranged in two rows, and the gap between two adjacent spacer bars is aligned with the top partition plate on the drum. The design of the two rows of spacer bars can ensure that the slab unloaded from the turning unit can stand stably on the movable plate.

[0011] As a further configuration of the above scheme, the pushing mechanism includes a strip-shaped receiving groove provided on the upper surface of the movable plate, a bidirectional screw is rotatably provided in the strip-shaped receiving groove, and one end of the bidirectional screw is connected to a screw motor, both ends of the strip-shaped receiving groove are provided with screw hole sliders that interact with the bidirectional screw, the screw hole sliders are connected with a support bar extending out of the strip-shaped receiving groove, and the ends of the two support bars are commonly connected with a pushing bar. The above is one of the specific design schemes of the pushing mechanism, which drives the bidirectional screw to rotate by the screw motor, so that the two screw hole sliders are close to each other, and in the process of the two screw hole sliders approaching each other, the push bar can be moved toward one side of the multi-layer hot press through the support bar, so that all the slabs mounted on the movable plate are pushed into the multi-layer hot press at the same time.

[0012] As a further configuration of the above scheme, linear slide rails are fixed on two opposite sides of the flip seat, and the moving plate is slidably connected to the two linear slide rails. The design of the linear slide rails can ensure that the moving plate can stably move linearly in the flip seat.

[0013] As a further configuration of the above scheme, the lower ends of the opposite sides of two adjacent spacer bars are connected with elastic limiting plates, the upper ends of the two elastic limiting plates are open, and the lower ends are linearly contracted. The design of the elastic limiting plates enables the slab unloaded from the flip unit to be stably limited in the gap between the two adjacent spacer bars, and ensures the stability of the slab during the subsequent rotation of the flip seat.

[0014] As a further configuration of the above scheme, a rotating rod is rotatably connected to the side of the U-shaped seat away from the flip unit, and strips are connected to the two ends of the rotating rod. The ends of the two strips are commonly connected to a correction push plate, and the rotating rod is connected to a hydraulic telescopic rod for self-rotation adjustment. The design of the above structure can move the correction push plate toward the side end of a row of slabs through the hydraulic telescopic rod after all the slabs are loaded into the loading unit, so that the row of slabs can be corrected and flushed, so that the slabs of a row of fiberboards can be neatly pushed into the hot press for hot pressing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The multi-layer hot press quick feeding device disclosed in the present invention receives the pre-pressed and cut slabs through a conveying unit, and then transfers them to a flip unit. The flip unit then transfers the slabs to the feeding unit one by one and puts them in an interval standing state, and then the feeding unit is rotated to a vertical state so that all the slabs are aligned with the hot pressing gaps in the multi-layer hot press one by one, and finally all the slabs are pushed into the hot pressing gaps at one time. The entire multi-layer hot press quick feeding device realizes the assembly line reception of the slabs in the fiberboard production line, and then pushes them all into the multi-layer hot press for processing at one time, without the need to transfer and stack the slabs, and then load them layer by layer. It not only simplifies the entire fiberboard production line, but also effectively improves the feeding efficiency during the operation of the multi-layer hot press, and reduces the heat loss on the hot pressing plate during loading and unloading.

[0016] The flipping unit in the present invention is improved and designed based on the flipping cooling machine, so that the flipping unit can, under the premise of carrying multiple slabs for transportation at the same time, also be able to directly enter the loading unit from the side end when the slabs are rotated and transported to a vertical state through the design of the pushing rod, extrusion wheel, connecting bar, supporting bar and track ring; at the same time, the moving plate in the loading unit is synchronized with the flipping action of the drum, so that the slabs unloaded from the flipping unit can stand one by one between the spacer bars, so that the slabs arranged in rows can be accurately aligned with the hot pressing gap of the multi-layer hot press after flipping; the structural design of the entire flipping unit is novel and ingenious, and with the function of the loading unit, the slabs pushed into the multi-layer hot press can be neatly arranged layer by layer, so that they can be pushed into the multi-layer hot press for processing at one time later, and have a better use effect.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 10 , and describes the application in detail with reference to embodiments. Example 1

[0021] Embodiment 1 discloses a multi-layer hot press rapid feeding device, refer to the attached Figure 1 and attached Figure 2, including a conveying unit 2 arranged on the ground 1, a turning unit 3 connected to the conveying unit 2 is arranged on the right side, a feeding unit 4 is arranged on the front side of the turning unit 3, and a multi-layer hot press (not shown in the figure) is arranged on the right side of the feeding unit 4. In addition, a control cabinet 5 for controlling the entire feeding device is arranged on the left side of the feeding unit 4. During operation, the fiberboard after pre-pressing and cutting is received by the conveying unit 2, and then sent to the turning unit 3, and the turning unit 3 turns the fiberboard from a horizontal state to a vertical state, and pushes it into the feeding unit 4 in the vertical state. When the fiberboards in the feeding unit 4 are received one by one and reach a set number, they stand up collectively, and finally are simultaneously pushed into the gap between the hot pressing plates of the multi-layer hot press.

[0022] The conveying unit 2 adopts a conventional roller conveyor and is connected to the tail end of the fiberboard pre-pressing and cutting production line. Figure 3 and attached Figure 4 The turning unit 3 includes a rotating drum 301 and a vertical plate 302. The vertical plate 302 is fixed on the ground 1, and then the roller on the rotating drum 301 is rotatably connected with the vertical plate 302, and a power source 303 for driving the rotating drum 301 to rotate is arranged on the vertical plate 302. A plurality of partitions 304 are evenly arranged circumferentially on the outer circumferential surface of the rotating drum 301, and the partitions 304 are arranged radially, and the partitions 304 at the horizontal position in the middle of the left end of the rotating drum 301 are flush with the conveying roller on the conveying unit 2, and an arc groove is opened on the ground 1 for the lower end partition 304 to rotate smoothly.

A support bar 308 is rotatably connected to the side of the partition 304 above the push rod 306, and the rotation connection between the support bar 308 and the partition 304 is set on the side close to the loading unit 4, and then a connecting bar 309 is rotatably connected between the support bar 308 and the end of the push rod 306, and the other end of the push rod 306 is extended out of the side end of the partition 304, and the extrusion wheel 310 is rotatably connected at its outer end. A track ring 311 that acts on the extrusion wheel 310 is coaxially fixed on the side of the vertical plate 302 facing the drum 301, and a protruding guide portion 312 extending to one side of the drum 301 is provided on the top of the track ring 311. When the extrusion wheel 310 rotates to interact with the raised guide portion 312, the push rod 306 can overcome the force of the elastic member 307 and move toward the side of the feeding unit 4, and then the connecting bar 309 can cause the support bar 308 to rotate toward the side of the feeding unit 4, thereby causing the fiberboard supported by the support bar 308 to rotate.

[0024] Reference Figures 5 to 8 The loading unit 4 includes a bottom box 401, a U-shaped seat 402 is fixed at the upper end of the bottom box 401, a flip seat 403 is arranged in the U-shaped seat 402, and the flip seat 403 is rotatably connected to the U-shaped seat 402 at one end close to the multi-layer hot press machine through a pin shaft, and the first gear 400 is connected to the outer end of the pin shaft extending out of the U-shaped seat 402. A first telescopic device 404 is fixedly installed on the U-shaped seat 402, and a first rack 405 meshing with the first gear 400 is connected to the telescopic end of the first telescopic device 404, so that the flip seat 403 can be rotated and adjusted between the horizontal and vertical states under the push of the first telescopic device 404 and the meshing of the gear and the rack.

[0025] Linear guide rails 406 are fixed on the front and rear opposite sides of the flip seat 403, a moving plate 407 is arranged between the two linear guide rails 406, and spacing bars 408 arranged in rows and at equal intervals are arranged at the front and rear ends of the upper surface of the moving plate 407, so that the fiberboard unloaded from the flip unit 3 can be placed between two adjacent spacing bars 408. A second rack 426 arranged parallel to the linear guide rail 406 is arranged on the lower surface of the moving plate 407, and then a rotating rod 427 arranged perpendicular to the second rack 426 is rotatably arranged in the U-shaped seat 402, and a second gear 428 meshing with the second rack 426 is arranged on the rotating rod 427. The outer end of the rotating rod 427 extending out of the U-shaped seat 402 is connected to a driven wheel 409 through a one-way transmission, and then a connecting shaft 410 is connected to the roller shaft of the rotating drum 301, which is provided with a driving wheel 411, and then a transmission member 412 is provided between the driven wheel 409 and the driving wheel 411. The specific driven wheel 409 and the driving wheel 411 can be selected from a sprocket wheel or a pulley, and the transmission member 412 can be selected from a transmission chain or a transmission belt accordingly. Through the above transmission design, the connecting shaft 410 will rotate during the rotation of the rotating drum 301, and then the rotating rod 427 will rotate synchronously, and then through the meshing transmission between the second gear 428 and the second rack 426, the movable plate 407 can be gradually moved along the linear slide rail 406, so that the fiberboards can be put into the gap between two adjacent spacer bars 408 one by one.

[0026] A second telescopic device 413 is provided at the end of the U-shaped seat 402 away from the multi-layer hot press, an electromagnet 414 is connected to the end of the first telescopic device 413, and a magnetic block 415 aligned with the electromagnet 414 is fixed on the lower surface of the movable plate 407. When the movable plate 407 needs to be pulled back to the initial state, current is passed through the electromagnet 414 so that the electromagnet 414 and the magnetic block 415 are adsorbed together, and then the second telescopic device 413 is controlled to retract to realize the movable plate 407 moving and resetting along the linear slide rail 406.

[0027] A strip receiving groove parallel to the linear guide rail 406 is provided on the upper surface of the moving plate 407, a bidirectional screw rod 416 is rotatably provided in the strip receiving groove, and a screw motor 417 for driving the bidirectional screw rod 416 is provided on the lower surface of the moving plate 407, and a bevel gear can be used for meshing transmission between the screw motor 417 and the bidirectional screw rod 416. Two screw hole sliders 418 are symmetrically provided at both ends of the strip receiving groove and are screwed to both ends of the bidirectional screw rod 416, and then a spreading strip 419 extending out of the strip receiving groove is rotatably connected to the screw hole slider 418, and the two spreading strips 419 are arranged in mirror symmetry, and finally a push strip 420 capable of simultaneously pushing all fiberboards to move is commonly connected to the movable ends of the two spreading strips 419.

[0028] During the operation of the multi-layer hot press fast feeding device disclosed in the embodiment 1, the conveying unit 2 conveys the fiberboards one by one to the turning unit 3, and each fiberboard is placed between two adjacent partitions 304. During the rotation of the partitions 304 from the horizontal state to the vertical state, the bottom of the fiberboard is supported by the corresponding support bar 308, and at the same time, due to the transmission effect of the transmission member 412, the second gear 428, the second rack 426 and other components, the moving plate 407 moves horizontally along the linear slide rail 406.

[0029] When the gap between the two spacer bars 408 on the movable plate 407 is aligned with the partition 304 in the upper vertical state, the action between the extrusion wheel 310 and the raised guide portion 312 will cause the push rod 306 to overcome the force of the elastic member 307 and move toward the upper material unit 4, and then the connecting bar 309 will cause the support bar 308 to move toward the gap between the spacer bars 408, and when the support bar 308 reaches a certain inclination angle, the fiberboard supported on the support bar 308 will slide into the gap between the spacer bars 408, until the support bar 308 rotates to a nearly vertical state, and the fiberboard that slides into the gap between the spacer bars 408 will stand in the gap between the spacer bars due to the offset of the center of gravity.

[0030] After repeating the above actions for several times, the movable plate 407 will move to the end near the multi-layer hot press, and a fiberboard will be installed in the gaps of all the spacer bars 408. Then the turning unit 3 will stop running, and the first telescopic device 404 will be started again, and the turning seat 403 will be rotated from the horizontal state to the vertical state through the meshing transmission between the rack and the gear. At this time, the multiple fiberboards received will also be in a horizontal state with equal intervals up and down, and aligned with the gaps between the hot pressing plates in the multi-layer hot press.

[0031] When the gaps between the multiple fiberboards and the multi-layer hot press plates are aligned, the screw motor 417 is started to rotate the bidirectional screw 416, and then the two screw hole sliders 418 are moved closer to each other by the action of the bidirectional screw 416, and then the push bar 420 is moved toward one side of the hot press by the action of the opening bar 419, thereby simultaneously pushing all the fiberboards into the gaps between the hot press plates of the hot press. Finally, the entire feeding unit 4 is controlled to reset, and after the reset, the flip unit 3 is started to repeat the above actions. Example 2

[0032] Example 2 discloses a multi-layer hot press rapid feeding device which is further optimized and improved based on the technical solution in Example 1. The similarities between the device and Example 1 will not be described again.

[0033] Reference Fig. 9 In this embodiment 2, on the one hand, elastic limit plates 421 are connected to the lower ends of the opposite sides of two adjacent spacer bars 408, and the two elastic limit plates 421 are arranged in a mirror-symmetrical manner, with an open design at the upper end and a linear shrinkage design at the lower end, so that when the flip unit 3 puts the fiberboard between the two spacer bars 408, it can pass through the gap between the elastic limit plates 421 and use the elastic force of the elastic limit plates 421 to clamp the fiberboard in the center, thereby avoiding the fiberboard from tilting during the flipping process of the flip seat 403 from a horizontal state to a vertical state, resulting in the inability to align with the hot pressing gap in the multi-layer hot press.

[0034] Secondly, in this embodiment 2, a rotating rod 422 is rotatably connected to the side of the U-shaped seat 402 away from the flip unit 3, and strips 423 are connected to both ends of the rotating rod 422, and then a correction push plate 424 acting on the side ends of the fiberboard is commonly connected to the ends of the two strips 423. Finally, a hydraulic telescopic rod 425 for driving the rotating rod 422 to rotate is also provided on the U-shaped seat 402 or the bottom box 401, so that when all the fiberboards are sequentially placed between the spacing strips 408, the hydraulic telescopic rod 425 is activated to rotate the correction push plate 424 toward the side ends of a row of fiberboards, thereby adjusting a row of fiberboards to be flush, ensuring that the fiberboards can be neatly pushed into the hot press for hot pressing.

[0035] The above are only 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 in the protection scope of the present invention.
