Description

Technical Field

[0001] The present invention relates to the field of feeding devices, and in particular to a feeding device for producing moisture-proof MDF boards and a use method thereof. Background Art

[0002] With the development of the board industry, various types of boards have emerged. Among them, MDF boards are often used in furniture manufacturing, construction, and interior decoration industries. MDF boards are density fiberboards, which are made of wood fiber or other plant fiber as raw materials, applied with urea-formaldehyde resin or other synthetic resins, and pressed under heating and pressure conditions. The density is in the range of 0.50 to 0.88 g / cm3.

[0003] In order to make MDF boards have various properties, various additives are often added during processing to improve the properties of the entire MDF board, such as adding moisture-proof agents to make the entire MDF board have good moisture-proof properties, or adding flame retardants to make the entire MDF board have better flame retardant properties.

[0004] However, in the existing process of adding moisture-proof agents, the commonly used processing and adding method is to apply a layer of moisture-proof agent or spray a layer of moisture-proof agent on the MDF board, so that the entire MDF board has better moisture-proof performance. The existing application is done manually, which is labor-intensive. Even if some application devices can be used for application, the moisture-proof agent on the application roller is not evenly distributed, resulting in uneven application of the moisture-proof agent. For this reason, we propose a moisture-proof MDF board production and adding device and a method for using the same. Summary of the Invention

[0005] The purpose of the present invention is to provide a moisture-proof MDF board production feeding device and a method of using the same. Through the feeding mechanism, the driving component can be conveniently used to drive the coating component to perform feeding processing. At the same time, the cloth pipe component and the feeding component can evenly distribute the moisture-proof agent on the coating component, thereby achieving uniform coating, and the cooperation of the extrusion component can enable the moisture-proof agent to quickly enter the coating velvet layer, avoiding the phenomenon of uneven coating caused by untimely filling of the moisture-proof agent.

[0006] To achieve the above object, the present invention provides the following technical solutions: In a first aspect, the present invention provides a feeding device for producing moisture-proof MDF boards, comprising a feeding machine body and a drive assembly located on top of the feeding machine body, wherein the feeding machine body is provided with a feeding mechanism, and the feeding mechanism comprises: The bracket assembly is arranged inside the feeding machine body, and the bracket assembly is provided with a locking assembly.

[0008] Preferably, the coating assembly includes a coating roller sleeved on the outer surface of the fabric tube assembly, a rotating sleeve fixedly connected to both ends of the coating roller, a plurality of discharge holes opened on the outer surface of the coating roller and a coating velvet layer fixedly arranged on the outside of the coating roller, and the coating roller is rotatably connected to the fabric tube assembly through the rotating sleeve.

[0009] Preferably, an extrusion assembly is provided below the fabric tube assembly, and the extrusion assembly includes two vertical rods fixedly connected to the bottom of the fabric tube assembly and an arc tube connected to the two vertical rods, and the arc tube is composed of two arc pieces symmetrically arranged up and down and side pieces fixedly connected to the ends of the two arc pieces.

[0010] Preferably, the bracket assembly includes a fixed sleeve fixedly connected to the end of the driving assembly, two movable rods inserted into the fixed sleeve, a mounting frame fixedly connected to the end of the movable rod and a mounting block fixedly connected to the end of the connecting circular tube, and each mounting frame is clamped with the corresponding mounting block.

[0011] Preferably, the feeding assembly includes a storage box located at the top of the feeding machine body, a delivery pump located inside the storage box, a feeding pipe fixedly connected to the output end of the delivery pump, two connecting hoses fixedly connected to the end of the feeding pipe, a connecting nozzle fixedly connected to the end of the connecting hose and a connecting cap sleeved on the outer surface of the connecting nozzle, and the connecting nozzle is plugged into one end of the corresponding connecting circular tube.

[0012] Preferably, the driving assembly includes a driving motor installed on the side of the feeding machine body, a driving threaded rod fixedly connected to the output end of the driving motor, a movable seat threadedly connected to the outer surface of the driving threaded rod, a telescopic cylinder fixedly connected to the bottom end of the movable seat, and two limit rods plugged into the middle of the movable seat, and the output end of the telescopic cylinder is fixedly connected to the middle of the fixed sleeve, and the two limit rods are both fixed on the feeding machine body.

[0013] Preferably, the number of the locking assemblies is set to two, and they are arranged at the ends of the corresponding movable rods. The locking assembly includes a locking sleeve fixedly connected to the end face of the movable rod, two movable columns plugged into the sides of the locking sleeve, an extrusion plate fixedly connected to one end of the movable column, a movable block fixedly connected to the other end of the movable column, an arc groove opened on the movable block, a conical block located between the two arc grooves, a locking threaded rod fixedly connected to the top of the conical block, a locking round block fixedly connected to one end of the locking threaded rod, and a sliding groove opened on the fixed sleeve.

[0015] In a second aspect, the present invention provides a method for using the aforementioned moisture-proof MDF board production feeding device, wherein the specific steps of the method are as follows: S1. Move the two movable rods along the inside of the fixed sleeve until the mounting block on the connecting round tube engages with the corresponding mounting frame. Then rotate the locking block to drive the locking threaded rod to rotate, thereby moving the tapered block downward, further squeezing the inner wall of the arc groove on the two movable blocks. This causes the movable column to drive the squeezing plate to squeeze the inner wall of the fixed sleeve, thereby installing the distribution pipe assembly and its application assembly: S2. The moisture-proofing agent is delivered by the delivery pump inside the storage box. The moisture-proofing agent enters the connecting hose through the feed pipe, then enters the connecting round pipe through the connecting nozzle, and then enters the discharge pipe. Due to the inclined setting of the discharge pipe and its trapezoidal profile, the moisture-proofing agent can quickly flow through the entire discharge pipe. The inner diameter of the discharge nozzle increases from both ends to the middle, which can also prevent the moisture-proofing agent from being completely discharged directly from the discharge nozzle at the end. It can be more evenly distributed throughout the entire discharge pipe. Then the moisture-proofing agent is discharged through the discharge nozzle and drips into the inside of the coating roller and passes through the discharge hole, thereby making the coating velvet layer moist as a whole: S3. The driving assembly drives the bracket assembly to move downward so that the smearing velvet layer contacts the plate. Then the driving assembly drives the bracket assembly to move horizontally, so that the smearing roller rotates, so that the smearing velvet layer evenly applies the moisture-proof agent to the plate, thereby achieving the purpose of adding material to the plate.

[0016] The technical effects and advantages of the present invention are as follows: The driving assembly drives the bracket assembly to move horizontally and downward at the same time, so that the bracket assembly drives the distribution pipe assembly and its coating assembly to move, so that the coating assembly contacts the MDF board, and the feeding assembly feeds the material, so that the distribution pipe assembly starts to discharge the material, so that the inner wall surface of the coating assembly is covered with the moisture-proof agent, so that the coating assembly can better evenly coat the MDF board, which not only saves manpower, but also evenly distributes the moisture-proof agent on the coating assembly, and the coating assembly itself is also more evenly coated, thereby improving the uniformity of adding the moisture-proof agent to the MDF board; By rotating the coating drum while the material dispensing tube assembly and its extrusion assembly do not rotate, the arc-shaped piece at the bottom of the arc-shaped tube is closer to the inner wall surface of the coating drum, so that the moisture-proof agent accumulated inside the coating drum can be quickly squeezed out from the discharge hole, thereby avoiding the moisture-proof agent from being unable to be discharged stably and continuously, resulting in uneven coating; By clamping the mounting block on the connecting round tube with the corresponding mounting frame, and then adjusting the extension length of the two movable rods, the fabric tube assembly is aligned with the MDF board, and then the locking block is rotated to make the locking block drive the locking threaded rod to rotate, so that the conical block squeezes the inner wall surface of the arc groove on the two movable blocks, thereby locking the position of the two movable rods, and then using the connection nozzle and the connecting cap to connect the connecting cap to the connecting round tube, thereby completing the assembly. For later disassembly, the reverse operation can be performed. This design makes it convenient for users to install or disassemble the fabric tube assembly and its application assembly, thereby facilitating the replacement of the fabric tube assembly and application assembly of appropriate sizes.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The present invention provides Figure 1-8The device for producing moisture-proof MDF boards shown in the figure comprises a feeding machine body 1 and a driving assembly 8 located on the top of the feeding machine body 1. The feeding machine body 1 is provided with a feeding mechanism, which comprises: a bracket assembly 2, which is arranged inside the feeding machine body 1, a locking assembly 3 is provided on the bracket assembly 2, and the bracket assembly 2 cooperates with the locking assembly 3 to change the overall length of the bracket assembly 2 by telescoping at both ends, and the driving assembly 8 can drive the bracket assembly 2 to move horizontally or vertically; a cloth pipe assembly 4, which is arranged below the bracket assembly 2, and the cloth pipe assembly 4 moves with the movement of the bracket assembly 2; a smearing assembly 5, which is rotatably arranged on the outside of the cloth pipe assembly 4, and the smearing assembly 5 can move the cloth pipe assembly 4 is applied with the moisture-proof agent discharged by the feeding component 7; the feeding component 7 is arranged above the smearing component 5, and the feeding component 7 can convey the moisture-proof agent to the dispensing pipe component 4; the driving component 8 drives the bracket component 2 to move horizontally and downward at the same time, so that the bracket component 2 drives the dispensing pipe component 4 and its smearing component 5 to move, so that the smearing component 5 contacts the MDF board, and the feeding component 7 feeds the material, so that the dispensing pipe component 4 starts to discharge the material, so that the inner wall surface of the smearing component 5 is covered with the moisture-proof agent, so that the smearing component 5 can better evenly apply the MDF board, which not only saves manpower, but also makes the moisture-proof agent evenly distributed on the smearing component 5, and the smearing component 5 itself is also more evenly applied, thereby improving the uniformity of adding the moisture-proof agent to the MDF board.

[0028] It should be further explained that the cloth pipe assembly 4 includes a discharge pipe 402 located at the bottom of the bracket assembly 2, two connecting circular tubes 401 fixedly connected to the end of the discharge pipe 402, a discharge protrusion 403 located at the bottom of the discharge pipe 402 and two groups of discharge nozzles 404 symmetrically arranged at the bottom end of the discharge pipe 402. The overall contour of the discharge pipe 402 is horizontally arranged in the middle and the two ends are inclined toward the middle, and the cross-sectional contour of the discharge pipe 402 is set to a trapezoid, the cross-sectional contour of the discharge protrusion 403 is set to an inverted V shape, and the overall contour of the discharge protrusion 403 changes with the overall contour of the discharge pipe 402, and the inner diameter size of each group of discharge nozzles 404 increases successively from the two ends to the middle; the combination of the trapezoidal discharge pipe 402 and its inverted V-shaped discharge protrusion 403 not only avoids the moisture-proof agent from being deposited in the discharge pipe 4 02 is accumulated at the bottom, resulting in waste. It is also for the convenience of setting up two sets of discharge nozzles 404, so that the moisture-proof agent can be evenly distributed on the coating component 5 regardless of whether the coating component 5 rotates forward or reversely. The overall contour of the discharge pipe 402 is horizontally set in the middle and the two ends are inclined toward the middle, and the inner diameter size of the discharge nozzle 404 increases successively from the two ends to the middle. This is to speed up the rapid flow of moisture-proof agent from the distribution pipe 402 from both ends to the middle, and at the same time avoid the moisture-proof agent being completely discharged from the discharge nozzle 404 at the end of the discharge pipe 402, resulting in the middle discharge nozzle 404 having no material to discharge. It can ensure that the discharge nozzles 404 at both ends can discharge material, and it is also convenient for the middle discharge nozzle 404 to discharge material smoothly, so that the entire distribution pipe component 4 is evenly distributed, so that the coating component 5 is evenly coated.

[0029] Furthermore, the coating assembly 5 includes a coating roller 501 sleeved on the outer surface of the fabric tube assembly 4, a rotating sleeve 504 fixedly connected to both ends of the coating roller 501, a plurality of discharge holes 502 opened on the outer surface of the coating roller 501 and a coating velvet layer 503 fixedly arranged on the outside of the coating roller 501, and the coating roller 501 is rotatably connected to the fabric tube assembly 4 through the rotating sleeve 504; the rotating sleeve 504 here can be embedded with a plurality of balls or directly installed with bearings, so as to facilitate the rotation of the rotating sleeve 504 along the connecting circular tube 401. When the discharge nozzle 404 discharges the moisture-proof agent, the moisture-proof agent is evenly distributed on the coating roller 501, and then comes to the coating velvet layer 503 from the discharge hole 502, so that the MDF board moisture-proof agent is added.

[0030] Furthermore, the feeding assembly 7 includes a storage box 701 located at the top of the feeding machine body 1, a conveying pump located inside the storage box 701, a feeding pipe 702 fixedly connected to the output end of the conveying pump, two connecting hoses 703 fixedly connected to the end of the feeding pipe 702, a connecting nozzle 704 fixedly connected to the end of the connecting hose 703 and a connecting cap 705 sleeved on the outer surface of the connecting nozzle 704, and the connecting nozzle 704 is plugged into one end of the corresponding connecting circular tube 401; through the operation of the conveying pump, the moisture-proof agent inside the storage box 701 is transported to the inside of the feeding pipe 702, and then transported to the inside of the connecting hose 703, and then enters the inside of the connecting circular tube 401 through the connecting nozzle 704, and finally quickly flows into the entire distribution pipe assembly 4.

[0031] It should be noted that an extrusion assembly 6 is provided below the fabric tube assembly 4, and the extrusion assembly 6 includes two vertical rods 601 fixedly connected to the bottom of the fabric tube assembly 4 and an arc tube 602 connected to the two vertical rods 601, and the arc tube 602 is composed of two arc pieces symmetrically arranged up and down and side pieces fixedly connected to the ends of the two arc pieces; when the coating roller 501 rotates, and the fabric tube assembly 4 and its extrusion assembly 6 do not rotate, the arc piece at the bottom of the arc tube 602 is closer to the inner wall surface of the coating roller 501, so that the moisture-proof agent accumulated inside the coating roller 501 can be quickly squeezed out from the discharge hole 502, thereby avoiding the inability to stably and continuously discharge the moisture-proof agent, resulting in uneven coating.

[0032] It should be noted that the bracket assembly 2 includes a fixed sleeve 201 fixedly connected to the end of the driving assembly 8, two movable rods 202 plugged into the fixed sleeve 201, a mounting frame 203 fixedly connected to the end of the movable rod 202, and a mounting block 204 fixedly connected to the end of the connecting circular tube 401, and each mounting frame 203 is snap-fitted to the corresponding mounting block 204; the number of locking assemblies 3 is set to two, and is arranged at the end of the corresponding movable rod 202, the locking assembly 3 includes a locking sleeve 301 fixedly connected to the end face of the movable rod 202, two movable columns 302 plugged into the side of the locking sleeve 301, The extrusion plate 303 is fixedly connected to one end of the movable column 302, the movable block 304 is fixedly connected to the other end of the movable column 302, the arc groove 305 is provided on the movable block 304, the tapered block 306 is located between the two arc grooves 305, the locking threaded rod 307 is fixedly connected to the top of the tapered block 306, the locking round block 308 is fixedly connected to one end of the locking threaded rod 307 and the sliding groove 309 is provided on the fixed sleeve 201; the inner arc profile of each arc groove 305 changes with the arc profile of the outer side of the tapered block 306, the cross-sectional profile of the locking sleeve 301 is set to H-shaped, and the locking threaded rod 307 is fixedly connected to the top of the tapered block 306. The outer surface of 7 is threadedly connected to the top of the locking sleeve 301; when the fabric tube assembly 4 needs to be assembled, the mounting block 204 on the connecting round tube 401 is clamped with the corresponding mounting frame 203. During the clamping process, the movable rod 202 will move along the fixed sleeve 201, and the locking threaded rod 307 will move along the inner part of the slide groove 309. When the mounting frame 203 and the mounting block 204 are clamped, the extension length of the two movable rods 202 is adjusted to align the fabric tube assembly 4 with the MDF board, and then the locking round block 308 is rotated so that the locking round block 308 drives the locking threaded rod 307 to rotate, so that the tapered block 306 rotates and moves downward, thereby squeezing the inner wall surface of the arc groove 305 on the two movable blocks 304, so that the movable column 302 drives the squeezing plate 303 to squeeze the inner wall surface of the fixed sleeve 201, thereby locking the position of the two movable rods 202, and then inserting the connecting nozzle 704 into the corresponding connecting circular tube 401, and then rotating the connecting cap 705 to connect the connecting cap 705 to the connecting circular tube 401, thereby completing the assembly. When disassembling later, the reverse operation can be performed. This design makes it convenient for users to install or disassemble the cloth tube assembly 4 and its smear assembly 5, thereby facilitating the replacement of the cloth tube assembly 4 and smear assembly 5 of appropriate sizes.

[0033] Furthermore, the driving assembly 8 includes a driving motor installed on the side of the feeding machine body 1, a driving threaded rod fixedly connected to the output end of the driving motor, a movable seat threadedly connected to the outer surface of the driving threaded rod, a telescopic cylinder fixedly connected to the bottom end of the movable seat, and two limit rods plugged into the middle of the movable seat, and the output end of the telescopic cylinder is fixedly connected to the middle of the fixed sleeve 201, and the two limit rods are both fixed on the feeding machine body 1; the driving motor rotates, driving the driving threaded rod to rotate, because the limit rod limits the movable seat, the movable seat will not rotate, thereby causing the movable seat to move horizontally, thereby causing the bracket assembly 2 to move horizontally, and the telescopic cylinder drives the bracket assembly 2 to move vertically. The driving assembly 8 can also be realized by other means of the existing technology, mainly to be able to realize horizontal and vertical movement of the bracket assembly 2.

[0034] The output pump, drive motor and telescopic cylinder mentioned above can be controlled by the control box on the feeding machine body 1. At the same time, a pressure sensor can be provided at the end of the telescopic cylinder to avoid crushing the MDF board. Other existing technologies can also be adopted, mainly to avoid the telescopic cylinder from moving downward, causing the coating component 5 to crush the MDF board.

[0035] A method for using a feeding device for producing moisture-proof MDF boards, the specific steps of the method are as follows: S1. Move the two movable rods 202 so that they move along the inside of the fixed sleeve 201 until the mounting block 204 on the connecting tube 401 is engaged with the corresponding mounting frame 203. Then, rotate the locking block 308 so that the locking block 308 drives the locking threaded rod 307 to rotate, thereby moving the tapered block 306 downward, further squeezing the inner wall surfaces of the arc grooves 305 on the two movable blocks 304. As a result, the movable column 302 drives the squeezing plate 303 to squeeze the inner wall surface of the fixed sleeve 201, thereby installing the dispensing pipe assembly 4 and its smearing assembly 5. S2. The moisture-proofing agent is delivered by the delivery pump inside the storage box 701. The moisture-proofing agent enters the interior of the connecting hose 703 through the feed pipe 702, and then enters the interior of the connecting circular tube 401 through the connecting nozzle 704, and then enters the interior of the discharge pipe 402. Due to the inclined setting of the discharge pipe 402 and its trapezoidal profile, the moisture-proofing agent can quickly circulate throughout the entire discharge pipe 402, and the inner diameter of the discharge nozzle 404 increases from both ends to the middle, which can also prevent the moisture-proofing agent from being completely discharged directly from the discharge nozzle 404 at the end, and can be more evenly distributed throughout the entire discharge pipe 402. Then the moisture-proofing agent is discharged through the discharge nozzle 404 and drips onto the interior of the coating roller 501, through the discharge hole 502, so that the coating velvet layer 503 is moistened as a whole: S3. The driving component 8 drives the bracket component 2 to move downward so that the smearing velvet layer 503 contacts the plate. Then the driving component 8 drives the bracket component 2 to move horizontally, so that the smearing roller 501 rotates, so that the smearing velvet layer 503 evenly applies the moisture-proof agent to the plate, thereby achieving the purpose of adding material to the plate.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.

The locking component (3) includes a locking sleeve (301) fixedly connected to the end face of the movable rod (202), two movable columns (302) plugged into the side of the locking sleeve (301), an extrusion plate (303) fixedly connected to one end of the movable column (302), a movable block (304) fixedly connected to the other end of the movable column (302), an arc groove (305) provided on the movable block (304), a conical block (306) located between the two arc grooves (305), a locking threaded rod (307) fixedly connected to the top of the conical block (306), a locking round block (308) fixedly connected to one end of the locking threaded rod (307), and a sliding groove (309) provided on the fixed sleeve (201).

9. A moisture-proof MDF board production feeding device according to claim 8, characterized in that: The inner arc profile of each arc groove (305) changes following the outer arc profile of the conical block (306), the cross-sectional profile of the locking sleeve (301) is set to be H-shaped, and the outer surface of the locking threaded rod (307) is threadedly connected to the top end of the locking sleeve (301).

10. A method for using a feeding device for producing moisture-proof MDF boards according to any one of claims 1 to 9, characterized in that: The specific steps of the method of use are as follows: S1. By moving the two movable rods (202), the two movable rods (202) move along the inside of the fixed sleeve (201) until the mounting block (204) on the connecting tube (401) is engaged with the corresponding mounting frame (203), and then rotating the locking round block (308) so that the locking round block (308) drives the locking threaded rod (307) to rotate, thereby causing the tapered block (306) to move downward, and further squeezing the inner wall surface of the arc groove (305) on the two movable blocks (304), so that the movable column (302) drives the squeezing plate (303) to squeeze the inner wall surface of the fixed sleeve (201), thereby installing the distribution pipe assembly (4) and its smearing assembly (5): S2. The moisture-proofing agent is delivered by the delivery pump inside the storage box (701). The moisture-proofing agent enters the inside of the connecting hose (703) through the feeding pipe (702), and then enters the inside of the connecting circular tube (401) through the connecting nozzle (704), and then enters the inside of the discharge pipe (402). Due to the inclined setting of the discharge pipe (402) and the trapezoidal setting of the profile, the moisture-proofing agent can quickly circulate throughout the discharge pipe (402), and the inner diameter of the discharge nozzle (404) increases from both ends to the middle, which can also prevent the moisture-proofing agent from being completely discharged directly from the discharge nozzle (404) at the end, and can be more evenly distributed throughout the inside of the discharge pipe (402). Then, the moisture-proofing agent is discharged through the discharge nozzle (404) and drips into the inside of the coating roller (501), through the discharge hole (502), thereby making the coating velvet layer (503) moist as a whole: S3, the driving assembly (8) drives the support assembly (2) to move downward, so that the smearing velvet layer (503) contacts the plate, and then the driving assembly (8) drives the support assembly (2) to move horizontally, so that the smearing roller (501) rotates, so that the smearing velvet layer (503) evenly smears the moisture-proof agent on the plate, thereby achieving the purpose of adding material to the plate.
