[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0020] Please refer to the attached Figure 1 To Attachment Figure 8 The invention describes a glue coating structure, a veneer device and a control method.

[0021] A veneer device includes a gluing structure 1, a reeling structure 4 and a veneer structure 7. The reeling structure 4 is used to reel the veneer material. The reeling structure 4 is adjacent to a third connecting roller 15 of the gluing mechanism to transport the veneer material of the reeling structure 4 to the gluing mechanism. The veneer structure 7 is used to transport an object to be pasted, and then the veneer material coated with glue by the gluing structure 1 is pasted onto the object to be pasted of the veneer structure 7.

[0022] The specific number of the unwinding structure 4 and the gluing structure 1 is two groups. One group of the unwinding structure 4 and the gluing structure 1 constitutes an upper veneer system 5, which is located at the second direction B end of the veneer structure 7 to correspond to the upper surface of the object to be pasted on the veneer structure 7. The other group of the unwinding structure 4 and the gluing structure 1 constitutes a lower veneer system 6, which is located at the first direction A end of the veneer structure 7 to correspond to the lower surface of the object to be pasted on the veneer structure 7.

[0023] The object to be attached is preferably rock wool. In other embodiments of the present invention, it can also be VC board, wood board, glass, etc.

[0024] The glue coating structure 1 includes a body 11, which is provided with a glue groove for placing glue. The body 11 is provided with a glue coating roller 12, which can rotate relative to the body 11, and the first direction A end of the glue coating roller 12 is immersed in the glue in the glue groove to coat the veneer material with glue. The glue coating roller 12 is provided with a glue coating component so that the glue coating roller 12 evenly coats the glue on the veneer material. The body 11 is provided with a rubber coating roller 14, which conveys the veneer material to the rubber coating roller 12 through the rubber coating roller 14. The body 11 is provided with a connecting component, and the rubber coating roller 14 and the rubber coating roller 12 are connected through the connecting component so that the rotation rate of the rubber coating roller 14 is the same as the rotation rate of the rubber coating roller 12.

[0025] Specifically, a liquid level detection probe is provided in the glue tank, and a low liquid level detection point and a high liquid level detection point are also provided in the glue tank. When the liquid level detection probe detects that the glue in the glue tank is lower than the liquid level set by the low liquid level detection point, an alarm is started, and the signal is transmitted to the glue pump. The glue pump starts and discharges the glue into the glue tank through the glue pump. When the liquid level detection probe detects that the glue in the glue tank is higher than the liquid level set by the high liquid level detection point, an alarm is started, and the signal is transmitted to the glue pump. The glue pump stops running, and the glue pump stops delivering glue to the glue tank.

[0026] Specifically, the glue coating assembly includes a plurality of sets of ring grooves 121 , and the plurality of ring grooves 121 are all formed on the glue coating roller 12 with the same gap to increase the penetration of glue.

[0027] Specifically, the connecting assembly includes a first sprocket 24 and a second sprocket 25, the first sprocket 24 is connected to the coating roller through a rod body, the first sprocket 24 is coaxially connected to the coating roller, the second sprocket 25 is connected to the rubber-coated roller 14 through a rod body, the second sprocket 25 is coaxially connected to the rubber-coated roller 14, the first sprocket 24 and the second sprocket 25 are connected through a chain 26, the transmission radius of the first sprocket 24 and the transmission radius of the second sprocket 25 are the same, so that the rotation rate of the rubber-coated roller 14 is the same as the rotation rate of the rubber-coated roller 12, and the first sprocket 24 and the second sprocket 25 are driven by the same power source, which further ensures that the rotation rate of the rubber-coated roller 14 is the same as the rotation rate of the rubber-coated roller 12.

[0028] Preferably, a third sprocket 27 is provided on the body 11, a slide groove is opened on the body 11, the third sprocket 27 is slidably connected to the slide groove, the third sprocket 27 can rotate relative to the body 11, the third sprocket 27 is located between the first sprocket 24 and the second sprocket 25, the third sprocket 27, the first sprocket 24 and the second sprocket 25 are connected by a chain 26, and the third sprocket 27 can slide along the slide groove by setting the third sprocket 27, so that when the position of the paint roller changes, it can slide along the slide groove through the third sprocket 27.

[0029] The paint roller can slide relative to the machine body 11 to correspond to different usage conditions. After the position of the paint roller is determined, the paint roller is fixed by a locking member so that the paint roller cannot slide but can only rotate.

[0030] The positions of the coating roller and the second sprocket 25 in the upper veneer system 5 and the lower veneer system 6 are different. After the position of the second sprocket 25 is moved, the third sprocket 27 compensates for the movement of the coating roller and the second sprocket 25, so that the third sprocket 27, the first sprocket 24 and the second sprocket 25 can always be connected through the chain 26.

[0031] Specifically, a driving mechanism 2 is provided on the body 11, and the driving mechanism 2 includes a motor 21, which is fixedly connected to the body 11, and a first gear 22 is fixedly connected to the output end of the motor 21. The rubber-coated roller 14 is connected to the second gear 23 through a rod body, and the first gear 22 and the second gear 23 are meshed. By starting the motor 21, the first gear 22 rotates. Since the first gear 22 and the second gear 23 are meshed, the second gear 23 drives the rubber-coated roller 14 to rotate, and then drives the coating roller to rotate through the connecting component. In other embodiments of the present invention, the output end of the motor 21 can also be directly connected to the rod body of the rubber-coated roller 14, as long as it can be ensured that the rubber-coated roller 14 rotates when the motor 21 is started.

[0032] Furthermore, a pressing roller 13 is provided on the machine body 11, and the pressing roller 13 is located at the second direction B end of the glue coating roller 12. An electric push rod 3 is provided on the machine body 11, and the output end of the electric push rod 3 is connected to the pressing roller 13, so that the gap between the pressing roller 13 and the glue coating roller 12 can be controlled by the electric push rod 3. By setting the pressing roller 13, the effect of ensuring the uniformity of the glue on the glue coating roller 12 is achieved, and the friction with the veneer material is increased by the pressing roller 13. By setting the electric push rod 3, the gap between the pressing roller 13 and the coating roller is adjusted, and after the coating roller moves, the pressing roller 13 moves synchronously through the electric push rod 3. Specifically, the output end of the electric push rod 3 is fixedly connected with a connecting frame, and the connecting frame is rotatably connected to the rod body on the pressing roller 13. When the output end of the electric push rod 3 is extended or retracted, the connecting frame drives the pressing roller 13 to slide along the first direction A or the second direction B, and the pressing roller 13 can rotate relative to the connecting frame, so that when the veneer material is conveyed, the pressing roller 13 rotates under the influence of friction.

[0033] Furthermore, a connecting roller group is provided on the machine body 11, and the connecting roller group can rotate relative to the machine body 11. The connecting roller group includes a first connecting roller 17, a second connecting roller 16 and a third connecting roller 15. The first connecting roller 17 is located on the side of the glue coating roller 12 away from the rubber coating roller 14, the second connecting roller 16 is located between the glue coating roller 12 and the rubber coating roller 14, and the third connecting roller 15 is located on the side of the rubber coating roller 14 away from the glue coating roller 12. After the veneer material enters the glue coating structure 1, it passes through the third connecting roller 15, the rubber coating roller 14 and the second connecting roller 16 in sequence, and then passes through the glue coating roller 12 to be glued by the glue coating roller 12, and then the veneer material with glue is transported out of the glue coating structure 1 through the first connecting roller 17. In other embodiments of the present invention, a fourth connecting roller, a fifth connecting roller, etc. may also be provided, as long as the normal transportation of the veneer material can be guaranteed.

[0034] Preferably, the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 can all slide relative to each other, and sliding grooves corresponding to the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 are opened on the body 11, and the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 slide in their respective sliding grooves to adjust the positions of the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15. After the positions of the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 are adjusted, the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 are fixed by a locking member, so that the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 can only rotate relative to the body 11 and cannot slide.

[0035] After the coating roller moves, the first connecting roller 17, the second connecting roller 16 and the third connecting roller 15 can all move to correspond to the position of the coating roller.

[0036] Specifically, the unwinding structure 4 includes a guide rail and a plurality of unwinding vehicles 41. The plurality of unwinding vehicles 41 are arranged side by side, and the plurality of unwinding vehicles 41 are all slidably connected to the guide rail, so that the unwinding vehicles 41 are moved by the guide rail.

[0037] Preferably, the unwinding structure 4 includes three unwinding carts 41, two of which unwind trolleys 41 unwind veneer materials with a wider width, and one unwinding cart 41 unwinds veneer materials with a narrower width, so as to meet the replacement of veneer materials of different widths, and serve as a backup. When the remaining amount of veneer materials is less than the alarm warning value, the material is docked with the spare roll in advance to avoid production line shutdown; the three unwinding carts 41 are arranged side by side, and the unwinding cart 41 suitable for veneer materials with a narrow width is placed at the back, and guide rails are provided on the ground. When veneer materials with a narrow width are used, the moving position is determined according to the amount of the two unwinding carts 41 with a wider width at the front end, and the unwinding cart is docked with the exhausted roll. At the same time, the unwinding cart for veneer materials with a wider width is also provided with guide rails at the bottom. When the veneer materials are used up, they are moved out of the equipment area to facilitate the replacement of the veneer materials.

[0038] Each unwinding vehicle 41 is provided with an unwinding roller 42 for unwinding the veneer material. The unwinding vehicle 41 is also provided with an unwinding motor 43. When unwinding, the unwinding motor 43 is started to rotate the unwinding roller 42.

[0039] Specifically, the veneer structure 7 includes a conveyor belt for conveying the objects to be veneered, and the transmission rate of the conveyor belt is synchronized with the transmission rate of the veneer structure 7 in real time to ensure the continuity of the production process.

[0040] Preferably, the veneer equipment is controlled by Profinet communication technology, specifically controlling the transmission rate of the conveyor belt to be synchronized with the transmission rate of the veneer structure 7 in real time, controlling the rotation rate of the glue coating roller 12 to control the amount of glue coating, controlling the rotation rate of the rubber coating roller 14 to be the same as the rotation rate of the rubber coating roller 12, and at the same time controlling the rotation rate of the unwinding roller 42 to be the same as the rotation rates of the rubber coating roller 14 and the rubber coating roller 12.

[0041] A control method for controlling the above-mentioned veneer device comprises the following steps: Controlling the rotation speed of the glue coating roller 12 to control the amount of glue coating; Control the rotation speed of the rubber coating roller 14 to be the same as the rotation speed of the rubber coating roller 12; Control the rotation speed of the unwinding roller 42 to be the same as the rotation speed of the rubber coating roller 14 and the rubber coating roller 12; The transmission speed of the conveyor belt is controlled to be synchronized with the transmission speed of the veneer structure 7 in real time.

[0042] Preferably, the controller is controlled by Siemens 1500-PLC, which mainly collects signals to control the action of the actuator. The entire system is controlled by intelligent software, which can realize continuous operation and real-time status monitoring of each device, and has functions such as fault alarm, display and automatic interlocking shutdown.

[0043] The present invention realizes online veneer of products, thereby improving productivity. Previously, offline production could only reach 10 m / min, while online production can reach 22 m / min, and the speed and productivity are increased by 1 times; originally, 2-3 persons were required to assist in offline veneer, while online production only requires one person to assist in replacing veneer materials, thereby reducing labor costs.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
