Description

Technical Field

[0001] This utility model relates to the field of impregnated paper, specifically a dual-purpose glue coating machine. Background Technology

[0002] Impregnated paper is made from a mixture of nonwoven wood pulp, PE, and plant-based binders. It is widely used in the veneer of cabinet and wardrobe bases. To facilitate the veneer process, a glue coater is used during impregnation. Existing glue coaters are mostly single-function, capable of either double-sided or single-sided glue application. To improve the utilization rate of glue coaters, a dual-purpose glue coater capable of both single-sided and double-sided application has been developed. Utility Model Content

[0003] The purpose of this invention is to provide a dual-purpose glue applicator to solve one or more of the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model discloses a dual-purpose glue applicator, which includes a frame, a first glue applicator assembly, and a second glue applicator assembly, both of which are mounted on the frame.

[0005] The first adhesive application assembly includes a correction roller, an upper adhesive application device, a lower adhesive application device, and a smoothing assembly. The smoothing assembly includes an upper smoothing assembly and a lower smoothing assembly. Both the upper adhesive application device and the upper smoothing assembly can move up and down. The first adhesive application assembly forms a first channel for material transmission.

[0006] The second adhesive application assembly includes a steering assembly and an adhesive application device. The steering assembly is configured correspondingly to the first adhesive application assembly and the adhesive application device. The second adhesive application assembly forms a second channel for material transport.

[0007] In some implementations,

[0008] The straightening roller, upper gluing device, lower gluing device, upper smoothing component, and lower smoothing component are sequentially arranged to form the first channel for material transport;

[0009] The frame includes an upper frame, a lower frame, and an auxiliary frame. The auxiliary frame is positioned corresponding to the upper and lower frames. The upper frame is located above the lower frame, and one end of the upper frame is hinged to the auxiliary frame. The upper glue-applying device is mounted on the upper frame. The auxiliary frame is equipped with a first lifting assembly and a second lifting assembly. One end of the first lifting assembly is hinged to the upper frame, and the first lifting assembly controls the lifting and lowering of the upper glue-applying device. The second lifting assembly is connected to an upper smoothing assembly, and the second lifting assembly controls the lifting and lowering of the upper smoothing assembly. The straightening roller, the lower glue-applying device, the lower smoothing assembly, and the second glue-applying assembly are all mounted on the lower frame. The heights of the upper glue-applying device and the upper smoothing assembly are adjusted by the first and second lifting assemblies to ensure their normal operation when the first glue-applying assembly is in operation. When the second glue-applying assembly is in operation, the height of the upper glue-applying device and the upper smoothing assembly is increased to prevent them from affecting the material being transported in the second channel.

[0010] In some implementations,

[0011] The frame is provided with two feed inlets and one discharge outlet. The two feed inlets are arranged on the same side of the frame. The discharge outlet and one feed inlet are located between the upper frame and the lower frame. The discharge outlet is corresponding to the steering assembly. The other feed inlet corresponds to the steering assembly and is located at the lower part of the lower frame.

[0012] The first lifting component controls the upper frame and the upper glue application device to rotate around the position on the upper frame that is hinged to the auxiliary frame, thereby achieving the purpose of controlling the lifting of the upper glue application device.

[0013] The dual-purpose glue applicator also includes a blower nozzle, which is mounted on the lower frame and is positioned corresponding to the discharge port.

[0014] In some implementations,

[0015] The steering assembly includes a first steering roller group, a second steering roller, and a third steering roller. The first steering roller group includes several first steering rollers, at least one of which is located on the outside of the frame and is positioned corresponding to the feed inlet. The third steering roller is located between the correction roller and the upper gluing device. The third steering roller is connected to a third lifting assembly, which controls the lifting of the third steering roller. The third lifting assembly raises the height of the material conveying in the second channel during use, preventing the bottom of the material from contacting the lower gluing device, the lower smoothing assembly, etc., and thus avoiding contamination. This ensures the gluing effect of the second gluing assembly.

[0016] The first steering roller group, the second steering roller, and the glue application device are all located below the first glue application assembly. The glue application device includes a glue application roller, a wire scraper, and pressure rollers located on both sides of the glue application roller. The first steering roller group, pressure roller, glue application roller, wire scraper, second steering roller, and third steering roller are arranged in sequence to form a second channel for material transmission.

[0017] In some implementations, the pressure roller is connected to a first auxiliary steering mechanism, which drives the pressure roller to rotate, thereby adjusting the force applied by the pressure roller to the material below and adjusting the distance between the pressure roller and the coating roller, so as to better ensure the coating effect of the coating roller on the material.

[0018] In some embodiments, the lower smoothing assembly includes an inner lower smoothing assembly and an outer lower smoothing assembly, with a blower nozzle disposed between the inner lower smoothing assembly and the outer lower smoothing assembly.

[0019] In some implementations, both the inner and outer lower smoothing components include a lower smoothing roller. In the outer lower smoothing component, the lower smoothing roller is connected to a second auxiliary steering mechanism. The second auxiliary steering mechanism is used to control the rotation of the corresponding lower smoothing roller, further reducing the impact of the lower smoothing roller at the end of the material conveying process on the material at the end of the second channel.

[0020] In some implementations, a glue container is provided below the glue-applying roller, and the amount of glue in the glue container is set corresponding to the lower part of the glue-applying roller.

[0021] In some implementations, a glue-receiving container is provided below both the upper and lower glue-applying devices to collect glue dripping from them.

[0022] Compared with the prior art, the beneficial effects of this utility model are: it can form a first channel and a second channel as needed; the use of the first channel can achieve double-sided coating of materials, and the use of the second channel can achieve single-sided coating of materials; in addition, this dual-purpose coating machine also has the advantages of easy operation and good coating effect.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0026] Figure 1 and Figure 2 Solid lines and arrows indicate the direction of movement of the corresponding components; dashed lines and arrows indicate the direction of material transport.

[0027] Please see Figure 1 and Figure 2 The figure shows a preferred embodiment of the present invention, which discloses a dual-purpose glue applicator. The dual-purpose glue applicator includes a frame, a first glue applicator assembly, a second glue applicator assembly, and a blower nozzle 9. The first glue applicator assembly and the second glue applicator assembly are both disposed on the frame, and the blower nozzle 9 is disposed on the lower frame 1, and the blower nozzle 9 is disposed corresponding to the discharge port.

[0028] The frame is provided with two feed inlets and one discharge outlet. The two feed inlets are located on the same side of the frame and are designated as the first feed inlet and the second feed inlet. The frame includes an upper frame 2, a lower frame 1, and an auxiliary frame. The discharge outlet and the first feed inlet are located between the upper frame 2 and the lower frame 1. The second feed inlet is located at the lower part of the lower frame 1. The auxiliary frame is provided corresponding to the upper frame 2 and the lower frame 1. The upper frame 2 is located above the lower frame 1, and one end of the upper frame 2 is hinged to the auxiliary frame. The auxiliary frame is provided with a first lifting assembly and a second lifting assembly. One end of the first lifting assembly is hinged to the upper frame 2.

[0029] The first adhesive application assembly includes a straightening roller 3, an upper adhesive application device 4, a lower adhesive application device 5, and a smoothing assembly. The straightening roller 3 is positioned corresponding to the first feed inlet and is used to introduce material between the upper adhesive application device 4 and the lower adhesive application device 5 through the first feed inlet, and can also pre-correct the material. The upper adhesive application device 4 is mounted on the upper frame 2. The smoothing assembly includes an upper smoothing assembly 6 and a lower smoothing assembly. The upper smoothing assembly 6 is connected to the second lifting assembly. The straightening roller 3, the lower adhesive application device 5, the lower smoothing assembly, and the second adhesive application assembly are all mounted on the lower frame 1. The lower smoothing assembly is positioned corresponding to the discharge port and includes an inner lower smoothing assembly 7 and an outer lower smoothing assembly 8. The height of the upper adhesive application device 4 and the upper smoothing assembly 6 is adjusted by the action of the first and second lifting assemblies, ensuring the normal operation of the upper adhesive application device 4 and the upper smoothing assembly 6 when the first adhesive application assembly is in operation, and raising the height of the upper adhesive application device 4 and the upper smoothing assembly 6 when the second adhesive application assembly is in operation.

[0030] The second coating assembly includes a steering assembly and a coating device. The steering assembly is positioned corresponding to the second inlet and outlet, and is also positioned corresponding to the first coating assembly and coating device. The steering assembly includes a first steering roller group, a second steering roller 11, and a third steering roller 14. The first steering roller group, the second steering roller 11, and the coating device are all positioned below the first coating assembly. The coating device includes a coating roller 15, a scraper bar 13, and pressure rollers 12 positioned on both sides of the coating roller 15. A glue container 20 is provided below the coating roller 15. The amount of glue in the glue container 20 corresponds to the lower part of the coating roller 15 to ensure that the surface of the coating roller 15 passes through the glue during rotation, thereby carrying the glue to the material surface. The pressure rollers 12 are positioned below the coating roller 15. Above the glue roller 15, the first steering roller group includes several first steering rollers 10, at least one of which is located on the outside of the frame and is located corresponding to the second feed inlet. The first steering roller group guides the material to the top of the glue coating roller 15 and the wire scraper 13. The third steering roller 14 is located between the correction roller 3 and the upper glue coating device 4. The third steering roller 14 is connected to the third lifting assembly 16. The third lifting assembly 16 controls the lifting of the third steering roller 14. The third lifting assembly 16 increases the height of the material transmission when the second glue coating assembly is in use, avoiding contact between the bottom of the material and the lower glue coating device 5, the lower smoothing assembly, etc., which would cause contamination and ensure the glue coating effect of the second glue coating assembly. The aforementioned pressure roller 12 can be connected to the first auxiliary steering mechanism 17. The first auxiliary steering mechanism 17 may include a first connecting arm and a telescopic mechanism. One end of the first connecting arm is connected to the pressure roller 12, and the other end of the first connecting arm is hinged to the telescopic mechanism. Any point between the two ends of the first connecting arm (this point can be set as needed) is sleeved on the connecting shaft, and the two ends of the connecting shaft are fixed to the lower frame 1. The telescopic mechanism drives the first connecting arm and the pressure roller 12 on it to rotate through telescopic movement, so as to adjust the force applied by the pressure roller to the material below, and adjust the distance between the pressure roller 12 and the coating roller 15, so as to better ensure the coating effect of the coating roller 15 on the material, and also facilitate the introduction of material between the pressure roller 12 and the coating roller 15.

[0031] The upper glue-applying device 4 and the lower glue-applying device 5 can meter and apply glue to both sides of the material. Other components controlling the operation of the first and second glue-applying components are not the focus of this invention and can be directly implemented using existing technology; therefore, they will not be described in detail here.

[0032] When the first gluing assembly is in use, the second gluing assembly is not operating. The straightening roller 3, upper gluing device 4, lower gluing device 5, inner lower smoothing assembly 7, upper smoothing assembly 6, blower nozzle 9, and outer lower smoothing assembly 8 are arranged along the material conveying direction, forming a structure as shown above. Figure 1The first material transport channel shown in the diagram allows for double-sided adhesive application of the material during transport. The bottom of the material contacts the alignment roller 3, the lower adhesive applicator 5, the inner lower smoothing assembly 7, and the outer lower smoothing assembly 8, while the upper surface contacts the upper adhesive applicator 4 and the upper smoothing assembly 6. This first channel enables double-sided adhesive application, and the inner lower smoothing assembly 7, the upper smoothing assembly 6, and the outer lower smoothing assembly 8 smooth the material surface and the adhesive on it. When the first adhesive applicator is not in use, the first lifting assembly controls the upper frame 2 and the upper adhesive applicator 4 to rotate around the hinged position on the upper frame 2 connected to the auxiliary frame, thus controlling the upper adhesive applicator 4 to rise. The second lifting assembly controls the upper smoothing assembly 6 to rise.

[0033] When the second gluing assembly is in use, the first gluing assembly is not in operation. The first lifting assembly can control the upper frame 2 and the upper gluing device 4 to rotate around the hinged position on the upper frame 2 with the auxiliary frame, thereby controlling the upper gluing device 4 to rise. The second lifting assembly controls the upper smoothing assembly 6 to rise to a preset position, and the third lifting assembly 16 controls the third steering roller 14 to rise to a preset position. At this time, the apex of the third steering roller 14 is higher than the height of the straightening roller 3, the lower gluing device 5, the inner lower smoothing assembly 7, and the outer lower smoothing assembly 8. The first steering roller group, pressure roller 12, gluing roller 15, pressure roller 12, wire scraper 13, second steering roller 11, third steering roller 14, and blower nozzle 9 are arranged in sequence as shown in the figure. Figure 2 The second material transport channel shown has a first steering roller group that introduces the material above the coating roller 15 and the squeegee 13. Two first auxiliary steering mechanisms 17 control the pressure roller 12 to press down on the material so that the lower surface (back side) of the material adheres to the coating roller 15. Then the material continues to be transported along the second channel. During the transport process, the squeegee 13 can measure and control the amount of adhesive applied to the lower surface of the material. The material is flipped by the subsequent second steering roller 11 and third steering roller 14. The air nozzle 9 blows air onto the upper surface (front side) of the material to form the material and prevent the material from falling onto the inner lower smoothing component 7 and the outer lower smoothing component 8 and being contaminated.

[0034] As described above, both the inner lower smoothing assembly 7 and the outer lower smoothing assembly 8 include a lower smoothing roller. The lower smoothing roller in the outer lower smoothing assembly 8 can be connected to a second auxiliary steering mechanism 18. The structure of the second auxiliary steering mechanism 18 can be the same as or similar to the structure of the first auxiliary steering mechanism 17, and can be implemented using existing structures; therefore, it will not be described in detail here. The second auxiliary steering mechanism 18 is used to control the corresponding lower smoothing roller to rotate a certain angle in the up and down directions without affecting the self-rotation of the lower smoothing roller. This angle can be set as needed, further reducing the impact of the lower smoothing roller at the end of the material conveying process on the material at the end of the second channel.

[0035] Below the upper glue coating device 4 and the lower glue coating device 5, there are respectively a first glue receiving container 191 and a second glue receiving container 192. The height of the top of the first glue receiving container 191 and the second glue receiving container 192 is less than the height of the top of the straightening roller 3, the top of the lower glue coating device 5, the top of the inner lower smoothing component 7, and the top of the outer lower smoothing component 8. This can effectively prevent the normal transmission of materials in the first channel and the second channel on the first glue receiving container 191 and the second glue receiving container 192. In addition, the first glue receiving container 191 and the second glue receiving container 192 can receive glue dripping from the upper glue coating device 4 and the lower glue coating device 5.

[0036] The above materials can be impregnated paper.

[0037] The first lifting assembly, the second lifting assembly, the third lifting assembly 16, and the telescopic mechanism can all be existing telescopic structures controlled by one or more of the following methods: electric, pneumatic, and hydraulic. Therefore, they will not be described in detail here.

[0038] All of the above-mentioned undisclosed matters can be implemented using existing technologies, so they will not be elaborated here.

[0039] The structure of the dual-purpose glue applicator described above can also be applied to other applications with the same or similar gluing (or printing) requirements.

[0040] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
