Description

Technical Field

[0001] The invention belongs to the technical field of glue coating equipment, and in particular relates to glue coating equipment with a pre-drying function. Background Art

[0002] Gluing is a process of applying glue evenly to the surface of an object to obtain a certain thickness of glue layer. Gluing can be done by using a brush, sprayer or other tools to evenly apply glue on the surface of an object to achieve the purpose of connection, fixation, sealing, etc. Gluing technology is widely used in the fields of construction, automobiles, electronics, furniture, etc., and is an indispensable part of modern industrial production.

[0003] The Chinese patent with publication number: CN215618719U discloses an efficient gluing device for solid wood splicing boards. Through the cooperation of gluing rollers, conveyors, driving gears, moving plates, forward and reverse motors, transmission gears, transmission toothed belts, limit plates, support rods and limit rollers, the solid wood splicing boards can be glued, which can meet the needs of use to a certain extent.

[0004] However, the gluing equipment can only apply glue to one solid wood board at a time, and there is a lack of immediate drying equipment for the solid wood board after gluing, resulting in the glue applied on the solid wood board not being able to cure quickly and being prone to fluidity, especially in cold seasons. The low temperature will slow down the solidification of the glue on the solid wood board, causing the staff to spend a longer time drying and curing, which can easily greatly reduce the gluing efficiency of the solid wood board.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a glue coating device with a pre-drying function.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0007] The object of the present invention is to provide a gluing device with a pre-drying function, which can solve the problem that the solid wood board cannot be dried immediately after the gluing is completed.

[0011] A pair of positioning plates are installed on the workbench and correspond to the dispensing valves, and a plurality of grooves are provided on the positioning plates;

[0012] The instant drying mechanism is installed on the Z-axis slide rail, and the instant drying mechanism includes a fixed plate, a glue discharge pipe is installed on the fixed plate, the glue discharge pipe is connected to the glue dispensing valve, an outer cover is installed on the fixed plate, the outer cover is arranged on the outside of the glue discharge pipe, a drying box is provided on one side of the outer cover, a controller and a mounting plate are installed in the drying box, a plurality of heating plates are installed on the mounting plate, the heating plates are electrically connected to the controller, and a avoidance groove is provided through the drying box.

[0013] In one or more embodiments of the present invention, the outer cover side wall is fixedly connected to a reinforcing rod, and the drying box side wall is fixedly connected to an adjusting rail. One end of the reinforcing rod is slidably disposed in the adjusting rail. By sliding the reinforcing rod in the adjusting rail, the relative height between the drying box and the glue dispensing valve can be adjusted, so that the heating plate in the drying box can be close to the solid wooden board fixed between a pair of positioning plates, so as to dry the glue coated on the solid wooden board and accelerate the curing speed of the glue.

[0014] In one or more embodiments of the present invention, a lifting motor is installed on the adjusting rail, and a screw is connected to the output end of the lifting motor. The screw is rotatably connected to the adjusting rail, and the screw is threadedly connected to the reinforcing rod. When the lifting motor is running, the lifting motor can drive the screw to rotate. Since the screw is threadedly connected to the reinforcing rod, the reinforcing rod is moved up and down in the adjusting rail by the action of the thread, thereby adjusting the relative height between the drying box and the dispensing valve.

[0015] In one or more embodiments of the present invention, a fixing ring is fixedly connected to the bottom wall of the fixing plate, a limiting plate is fixedly connected to the end of the outer cover, a rotating groove matching the limiting plate is provided in the fixing ring, and the outer cover and the fixing plate can be relatively rotated through the cooperation between the limiting plate and the rotating groove to adjust the position of the drying box so that the drying box is always on the moving rear side of the glue discharge pipe, so as to immediately dry the glue applied on the solid wood board.

[0016] In one or more embodiments of the present invention, the side wall of the outer cover is connected to an outer gear ring, the upper bottom wall of the Z-axis slide rail is connected to a mounting seat, a rotating motor is installed on the mounting seat, and the output end of the rotating motor is connected to a driving gear, and the driving gear is meshed with the outer gear ring.

[0017] In one or more embodiments of the present invention, a barrier curtain is installed in one of the avoidance grooves. The barrier curtain is arranged on a side of the drying box close to the dispensing valve. The barrier curtain is made of rubber. The barrier curtain can seal the avoidance groove to prevent hot air in the drying box from being discharged from the avoidance groove, thereby avoiding waste of thermal energy resources.

[0018] In one or more embodiments of the present invention, an air suction pump is installed on the side wall of the drying box, and the air suction end of the air suction pump is connected to a straight pipe. A plurality of evenly distributed air suction heads are installed on the straight pipe, and the air suction head corresponds to another avoidance groove. When the air suction pump is running, the air suction pump can form a negative pressure in the straight pipe through the air suction end, and the straight pipe can absorb the heat in the drying box through the plurality of air suction heads and the avoidance grooves so as to recycle the heat.

[0019] In one or more embodiments of the present invention, the air outlet of the suction pump is connected to an adsorption box, and the adsorption box is installed on the top wall of the drying box, and the gas sucked by the suction pump will be transported to the adsorption box;

[0021] In one or more embodiments of the present invention, the adsorption box is connected to a gas pipe, one end of which is disposed in the outer cover, and the gas in the adsorption box can enter the outer cover through the gas pipe. Since the gas carries heat, the glue flowing in the glue discharge pipe can be heated by thermal radiation to increase the temperature of the glue, which can not only improve the adhesion of the glue, but also avoid the problem of slow subsequent curing speed due to the low temperature of the glue;

[0022] A blocking plate is provided in the outer cover, and the blocking plate is provided on the lower side of the gas pipe. The blocking plate is fixedly connected to the side wall of the outer cover and is rotatably connected to the side wall of the glue discharge pipe. A plurality of through holes are provided on the blocking plate. The blocking plate can slow down the discharge speed of the gas between the outer cover and the glue discharge pipe so that the heat in the gas can be transferred to the glue discharge pipe for heating the glue flowing in the glue discharge pipe. At the same time, the flow direction of the gas can also be guided by the setting of the blocking plate and the through holes to form an air curtain between the outer cover and the glue discharge pipe. The air curtain can block the glue to avoid splashing when the glue is discharged through the glue discharge pipe, so as to ensure the coating effect of the glue on the solid wood board.

[0023] In one or more embodiments of the present invention, a branch pipe is connected to the gas supply pipe, an air duct is provided in the drying box, one end of the branch pipe is provided in the air duct, and part of the gas exhausted in the adsorption box will enter the air duct through the branch pipe, so as to accelerate the gas flow in the drying box, so that the heat generated by the heating plate can fully dry the glue coated on the solid wood board, so as to increase the curing speed of the glue.

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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 creative work should fall within the scope of protection of the present invention.

[0043] like Figures 1 to 14 As shown, a gluing device with a pre-drying function in one embodiment of the present invention includes a workbench 1, a pair of positioning plates 2 and an instant drying mechanism 3.

[0044] Among them, a pair of X-axis slide rails 101 are installed on the workbench 1, a Y-axis slide rail 102 is installed between the pair of X-axis slide rails 101, and a Z-axis slide rail 103 is installed on the Y-axis slide rail 102. Through the mutual cooperation of the X-axis slide rail 101, the Y-axis slide rail 102 and the Z-axis slide rail 103, the position of the dispensing valve 104 can be flexibly adjusted, so that the dispensing valve 104 can be used to apply glue to the solid wood board to meet the processing requirements of solid wood board gluing.

[0045] In addition, a glue dispensing valve 104 is installed on the Z-axis slide rail 103, and the glue dispensing valve 104 is used to apply glue to the solid wood board.

[0046] like Figures 1 to 14 As shown, a pair of positioning plates 2 are installed on the workbench 1 and correspond to the dispensing valve 104. A plurality of grooves are provided on the positioning plate 2. Multiple solid wood boards can be placed between the corresponding pair of grooves at one time, and then the dispensing valve 104 is used for gluing to improve the gluing efficiency of the solid wood boards.

[0047] like Figures 1 to 14 As shown, the instant drying mechanism 3 is installed on the Z-axis slide rail 103. The instant drying mechanism 3 is used to instantly dry the solid wood board after gluing. For example, after the glue dispensing valve 104 moves 5 cm, the drying box 304 immediately follows up to achieve gluing and drying at the same time, thereby avoiding the fluidity of the glue coated on the solid wood board. At the same time, in cold seasons, it can also speed up the curing speed of the glue on the solid wood board and shorten the solidification time of the glue on the solid wood board, so as to improve the gluing efficiency of the solid wood board.

[0048] The instant drying mechanism 3 includes a fixing plate 301, and the fixing plate 301 is used to fix a glue discharge pipe 302. The fixing plate 301 is provided with a glue discharge pipe 302, and the glue discharge pipe 302 is connected to the glue dispensing valve 104. The glue in the glue dispensing valve 104 will enter the glue discharge pipe 302, and then be discharged through the glue discharge pipe 302 to be coated on the solid wood board, so as to meet the processing requirements of gluing the solid wood board.

[0049] In addition, an outer cover 303 is installed on the fixed plate 301, and the outer cover 303 is arranged on the outside of the glue discharge pipe 302. The outer cover 303 is used to install a drying box 304 and is also used to temporarily store hot gas. The hot gas is used to heat the flowing glue in the glue discharge pipe 302 to increase the glue outlet temperature, which can not only improve the adhesion of the glue to the solid wood board, but also avoid the problem of slow curing speed and long solidification time due to the low internal temperature of the glue.

[0050] Preferably, the glue discharge pipe 302 is made of a heat-conducting material, such as copper alloy, and the outer cover 303 is made of a heat-insulating material, such as ceramic fiber. When the hot gas is temporarily stored between the glue discharge pipe 302 and the outer cover 303, the hot gas passes through the glue discharge pipe 302 to heat the glue flowing in the glue discharge pipe 302, so as to increase the glue outlet temperature, especially in cold seasons, to avoid the problem of poor adhesion and slow solidification speed caused by too low glue temperature, thereby improving the glue coating quality of the solid wood board.

[0051] Specifically, a drying box 304 is provided on one side of the outer cover 303 , a controller 305 and a mounting plate 306 are installed in the drying box 304 , a plurality of heating plates 307 are installed on the mounting plate 306 , and the heating plates 307 are electrically connected to the controller 305 .

[0052] The controller 305 can be used to control the operating state of the heating plate 307, including controlling the operating time and heating power of the heating plate 307. When the heating plate 307 is in operation, it can release heat to immediately dry the glue applied on the solid wood board to avoid the fluidity of the glue, especially in cold seasons, and can also improve the adhesion of the glue, thereby improving the gluing quality of the solid wood board.

[0053] Preferably, a temperature sensor is also provided in the drying box 304, and the temperature sensor is used to detect the temperature in the drying box 304 and send feedback data to the controller 305. The controller 305 can dynamically adjust the power of the heating plate 307 according to the curing temperature range of the glue (such as 50-80°C). If the hot melt temperature of the glue is greater than 100°C and the curing temperature is less than 80°C, when the temperature in the drying box 304 exceeds the set threshold, the controller 305 will reduce the power of the heating plate 307 to ensure that the temperature in the drying box 304 is stable within the range required for the curing of the glue, and to prevent the glue from entering the hot melt state, so as to ensure the quality of the glue coating of the solid wood board.

[0054] like Figures 1 to 14 As shown, the drying box 304 is provided with a avoiding groove 308, and the avoiding groove 308 can make the heating plate 307 close to the solid wood board. Figure 2 The state shown is used to improve the drying efficiency of the heating plate 307 on the glue on the solid wood board, thereby greatly improving the curing speed of the glue.

[0055] Among them, the side wall of the outer cover 303 is fixedly connected with a reinforcing rod 309, and the side wall of the drying box 304 is fixedly connected with an adjusting rail 310, and one end of the reinforcing rod 309 is slidably arranged in the adjusting rail 310. By sliding the reinforcing rod 309 in the adjusting rail 310, the relative height between the drying box 304 and the dispensing valve 104 can be adjusted, so that the heating plate 307 in the drying box 304 can be close to the solid wood board, so as to improve the drying efficiency of the heating plate 307 for the glue and accelerate the curing speed of the glue.

[0056] Preferably, the reinforcing rod 309 can also be replaced by an electric telescopic rod, and the drying box 304 and the dispensing valve 104 move synchronously through the electric telescopic rod. When the dispensing valve 104 completes the gluing of a certain section of the solid wood board, the drying box 304 immediately moves to the top of the section for drying. The controller 305 can automatically calculate the optimal moving interval between the drying box 304 and the dispensing valve 104 according to the length of the gluing path and the curing time of the glue, that is, automatically determine the telescopic length of the reinforcing rod 309 to ensure that the drying time does not occupy the gluing cycle.

[0057] In addition, a lifting motor 311 is installed on the adjustment rail 310 , and a screw rod 312 is connected to the output end of the lifting motor 311 . The screw rod 312 is rotatably connected to the adjustment rail 310 , and the screw rod 312 is threadedly connected to the reinforcing rod 309 .

[0058] When the lifting motor 311 is running, the lifting motor 311 can drive the screw rod 312 to rotate, and since the screw rod 312 is threadedly connected with the reinforcing rod 309, the reinforcing rod 309 is moved up and down in the adjusting rail 310 by the action of the thread, thereby adjusting the relative height between the drying box 304 and the dispensing valve 104.

[0059] like Figures 1 to 14 As shown, a fixing ring 313 is fixedly connected to the bottom wall of the fixing plate 301 , a limiting plate 314 is fixedly connected to the end of the outer cover 303 , and a rotating groove 315 matching the limiting plate 314 is provided in the fixing ring 313 .

[0060] Through the cooperation between the limit plate 314 and the rotating groove 315, the outer cover 303 and the fixed plate 301 can be relatively rotated to adjust the position of the drying box 304. The drying box 304 rotates 180° each time, so that the drying box 304 can always be on the moving rear side of the glue discharge pipe 302, so as to immediately dry the glue applied on the solid wood board to avoid the fluidity of the glue.

[0061] The outer cover 303 has a side wall connected to an outer gear ring 316 , the upper bottom wall of the Z-axis slide rail 103 has a mounting seat 317 , a rotary motor is mounted on the mounting seat 317 , and a driving gear 318 is connected to the output end of the rotary motor, which is meshed with the outer gear ring 316 .

[0062] When the rotary motor is running, the rotary motor can drive the driving gear 318 to rotate. Since the driving gear 318 is meshed with the outer gear ring 316, and the limit plate 314 rotates in the rotation groove 315, the outer gear ring 316 is meshed with the driving gear 318, and can drive the outer cover 303 and the fixed plate 301 to rotate relative to each other, that is, the drying box 304 can rotate 180 degrees with the outer cover 303, so that the drying box 304 is always at the moving rear side of the glue discharge pipe 302, so as to dry the glue applied on the solid wood board immediately.

[0063] In addition, a curtain 319 is installed in one of the avoidance grooves 308. The curtain 319 is arranged on the side of the drying box 304 close to the dispensing valve 104. The curtain 319 is made of rubber. The curtain 319 can block the avoidance groove 308 to prevent the hot air in the drying box 304 from being discharged from the avoidance groove 308, thereby avoiding the waste of heat energy resources.

[0064] Specifically, a blocking plate 320 is provided in the outer cover 303, and the blocking plate 320 is provided at the lower side of the gas delivery pipe 407. The blocking plate 320 is fixedly connected to the side wall of the outer cover 303 and is rotatably connected to the side wall of the rubber discharge pipe 302. The blocking plate 320 is provided with a plurality of through holes 321. The arrangement positions of the plurality of through holes 321 are as shown in FIG. Fig.13 As shown, when the gas is discharged through the through hole 321 , an air curtain can be formed on both sides of the solid wood board to block the glue and prevent the glue from splashing when it is discharged through the glue discharge pipe 302 .

[0065] The sealing plate 320 can slow down the discharge speed of the gas between the glue discharge pipe 302 and the outer cover 303 so that the heat in the gas can be transferred to the glue discharge pipe 302 to heat the glue flowing in the glue discharge pipe 302. At the same time, through the setting of the sealing plate 320 and the through hole 321, the flow direction of the gas can also be guided to form an air curtain between the outer cover 303 and the glue discharge pipe 302. The air curtain can block the glue to avoid splashing when the glue is discharged through the glue discharge pipe 302, so as to ensure the coating effect of the glue on the solid wood board.

[0066] Preferably, a control box is installed on the side wall of the workbench 1, and the control box is electrically connected to the controller 305, the lifting motor 311, the rotating motor and the suction pump 4, so as to facilitate the control of the operation of the controller 305, the lifting motor 311, the rotating motor and the suction pump 4.

[0067] like Figures 1 to 14 As shown, an air suction pump 4 is installed on the side wall of the drying box 304, and a straight pipe 401 is connected to the air suction end of the air suction pump 4. A plurality of evenly distributed air suction heads 402 are installed on the straight pipe 401, and the air suction heads 402 correspond to another avoidance groove 308.

[0068] When the suction pump 4 is running, the suction pump 4 can form a negative pressure in the straight pipe 401 through the suction end, and the straight pipe 401 can absorb the heat in the drying box 304 through a plurality of suction heads 402 and the avoidance grooves 308, so as to avoid the heat in the drying box 304 from being discharged through the avoidance grooves 308 when the drying box 304 moves, thereby avoiding the waste of heat and allowing the heat to be recycled.

[0069] The air outlet of the air suction pump 4 is connected to an adsorption box 403 , which is installed on the top wall of the drying box 304 . The gas sucked by the air suction pump 4 will be transported into the adsorption box 403 .

[0070] In addition, a plurality of grids 404 are provided in the adsorption box 403, and filter cotton 405 and activated carbon balls 406 are respectively provided between adjacent pairs of grids 404. The filter cotton 405 and activated carbon balls 406 can filter the gas in the adsorption box 403 to remove toxic and harmful substances in the gas and prevent toxic and harmful substances from polluting the environment.

[0071] Specifically, the adsorption box 403 is connected with an air pipe 407, one end of which is disposed in the outer cover 303. The gas in the adsorption box 403 can enter between the outer cover 303 and the glue discharge pipe 302 through the air pipe 407. Since the gas carries heat, the glue flowing in the glue discharge pipe 302 can be heated by thermal radiation to increase the glue outlet temperature, which can not only improve the adhesion of the glue, but also avoid the problem of slow subsequent curing speed due to the low glue temperature.

[0072] In addition, a branch pipe 408 is connected to the gas delivery pipe 407, and an air passage 322 is provided in the drying box 304, and one end of the branch pipe 408 is provided in the air passage 322. Part of the gas exhausted from the adsorption box 403 will enter the air passage 322 through the branch pipe 408, so as to accelerate the gas flow in the drying box 304, so that the heat generated by the heating plate 307 can fully dry the glue coated on the solid wood board, so as to increase the curing speed of the glue.

[0073] When in use, several solid wood boards are placed in the corresponding grooves of the positioning plate 2. Figure 1 The state shown can realize the fixing of the solid wood board.

[0074] Through the mutual cooperation of the X-axis slide rail 101, the Y-axis slide rail 102 and the Z-axis slide rail 103, the position of the dispensing valve 104 can be adjusted so that the dispensing valve 104 and the glue discharge tube 302 can be used to apply glue to the solid wood board to meet the processing requirements of solid wood board gluing.

[0075] When the glue discharge pipe 302 is applying glue to the solid wood board, the lifting motor 311 is controlled to operate, and the lifting motor 311 can drive the screw rod 312 to rotate. Since the screw rod 312 is threadedly connected to the reinforcing rod 309, the reinforcing rod 309 is moved downward in the adjustment rail 310 by the action of the thread, and then the height of the drying box 304 can be adjusted downward, so that the heating plate 307 in the drying box 304 is close to the solid wood board. When the solid wood board is engaged in the avoidance groove 308, that is, Figure 2 In the state shown, the lifting motor 311 is stopped.

[0076] The heating plate 307 is operated and can generate heat. Since the heating plate 307 is close to the solid wood board, the heat released by the heating plate 307 can dry the glue, thereby instantly drying the glue coated on the solid wood board to avoid the fluidity of the glue, especially in cold seasons. The curing speed of the glue can be accelerated to a certain extent, and the solidification time of the solid wood board glue can be shortened, so as to improve the gluing efficiency of the solid wood board.

[0077] When the heating plate 307 dries the glue, the suction pump 4 can also be operated. The suction pump 4 can form a negative pressure in the straight pipe 401 through the suction end. The straight pipe 401 can then absorb the heat in the drying box 304 through a plurality of suction heads 402 and the avoidance groove 308, so as to avoid the heat in the drying box 304 from being discharged through the avoidance groove 308 when the drying box 304 moves, thereby avoiding the waste of heat and recycling the heat. The gas absorbed by the suction pump 4 enters the adsorption box 403, and is used to remove toxic and harmful substances in the gas under the action of the filter cotton 405 and the activated carbon ball 406, so as to avoid toxic and harmful substances from polluting the environment.

[0078] The gas in the adsorption box 403 can enter between the outer cover 303 and the glue discharge pipe 302 through the gas pipe 407. Since the gas carries heat, the glue flowing in the glue discharge pipe 302 can be heated by thermal radiation to increase the temperature of the glue. This can not only improve the adhesion between the glue and the solid wood board, but also avoid the problem of slow subsequent curing speed due to the glue temperature being too low.

[0079] The blocking plate 320 between the glue discharge pipe 302 and the outer cover 303 can slow down the exhaust speed of the gas between the glue discharge pipe 302 and the outer cover 303, so that the heat in the gas can be transferred to the glue discharge pipe 302, which is used to heat the glue flowing in the glue discharge pipe 302. At the same time, through the setting of the blocking plate 320 and the through hole 321, the flow direction of the gas can also be guided to form an air curtain between the outer cover 303 and the glue discharge pipe 302. The air curtain can block the glue and avoid splashing when the glue is discharged through the glue discharge pipe 302, so as to ensure the coating effect of the glue on the solid wood board.

[0080] When the glue discharge hose 302 has finished gluing one of the solid wood boards, the lifting motor 311 is controlled to operate, thereby causing the drying box 304 to rise, so that the drying box 304 is away from the solid wood board. Then the rotating motor is controlled to operate, and the rotating motor can drive the driving gear 318 to rotate. Since the driving gear 318 is meshed with the outer gear ring 316, and the limit plate 314 rotates in the rotating groove 315. Therefore, the outer gear ring 316 is meshed with the driving gear 318, and can drive the outer cover 303 and the fixed plate 301 to rotate relative to each other, so as to realize the reversal of the drying box 304, that is, the drying box 304 can rotate 180° with the outer cover 303, so that the drying box 304 is always on the moving rear side of the glue discharge hose 302. The lifting motor 311 is controlled to operate, so that the drying box 304 descends, so that the heating plate 307 is close to the solid wood board.

[0081] The glue dispensing valve 104 and the glue discharge pipe 302 are then used to apply glue to the solid wood board. The heating plate 307 at the rear side of the movement can continue to dry the glue on the solid wood board immediately, which can accelerate the curing speed of the glue on the solid wood board to a certain extent and shorten the solidification time of the glue on the solid wood board to improve the gluing efficiency of the solid wood board. After all the solid wood boards are glued, they are finally dried to make the glue on the surface of the solid wood board completely dry.
