Description

Technical Field

[0001] This utility model belongs to the field of solid wood board production and processing technology, specifically referring to a glue application device for solid wood core boards. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesive. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneer layers glued perpendicular to each other. The multi-layered veneer in the center of the plywood is called the core board.

[0003] The manufacturing process of plywood requires applying glue to both sides of multi-layer core boards, and finally processing them into shape through bonding, hot pressing, and cutting. In the glue application process, traditional equipment does not have a glue collection system, causing excess glue on the rollers to drip onto the ground, thus forming a localized pollution area. This area is not only inconvenient for material transportation and personnel passage, but also causes waste of raw materials when processing plywood for a long time. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a solid wood core board glue application device, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a glue application device for solid wood core board, including a cleaning component and a glue application component, wherein the cleaning component is symmetrically arranged on both sides of the glue application component.

[0006] The cleaning component is used to collect and gather the glue dripping from the glue application component.

[0007] The cleaning component includes a touch rod and a mounting base plate. The mounting base plate has two sets of touch rods on both sides, and the two sets of touch rods are axially symmetrical about the center of the cleaning component.

[0008] The adhesive application assembly includes two sets of inclined base plates, and the two sets of inclined base plates are arranged in a mirror image.

[0009] Furthermore, the cleaning assembly also includes a base frame, connecting columns, mounting plates, and slide rails.

[0013] Furthermore, the cleaning assembly also includes a support column, a sliding rail, a sliding connecting seat, a spring, and a rotating connecting plate;

[0014] The sliding base has multiple sets of support columns fixedly connected to its rear. A mounting base plate is fixedly connected to the rear of each set of support columns. The connecting shaft passes through the mounting base plate and can rotate within it. The mounting base plate has a set of sliding rails at its upper and lower parts. Each set of sliding rails has a set of sliding connecting seats movably connected inside it. The two sets of sliding connecting seats are 180° axially symmetrical about the connecting shaft. The tail of the connecting shaft has two sets of rotating connecting plates, also 180° axially symmetrical about the connecting shaft. A set of springs is fixedly connected between each set of rotating connecting plates and its front sliding connecting seat.

[0015] Furthermore, the adhesive application assembly also includes a base, a motor, a power component, and a side sealing plate.

[0016] The base consists of two sets, which are arranged in a mirror image.

A set of side sealing plates is fixedly connected to both sides of the two sets of bases, and a set of inclined bottom plates is fixedly connected to the lower part of each set of side sealing plates.

[0017] Furthermore, the adhesive application assembly also includes a brush port, an auxiliary roller, a pouring port, an upper roller, and a lower roller.

[0018] Each set of side sealing plates has a brush movable opening in the middle, which is cut through the side sealing plate. The upper roller is rotatably connected to the upper part of the base, and the lower roller is rotatably connected to the lower part of the upper roller. Two sets of auxiliary rollers are rotatably connected to the bottom of the lower roller. Each set of inclined base plates has a tilting opening in the center, which is cut through the inclined base plate.

[0019] Furthermore, the two sets of inclined bottom plates are mirror images of each other with the central axis of the rollers above them as the reference point, and the part of the inclined bottom plate closest to the central axis of the rollers is the highest point.

[0020] Furthermore, the connecting shaft passes through the brush's movable opening, and the brush is located inside the space formed by the side sealing plate and the inclined bottom plate.

[0021] The beneficial effects of this utility model by adopting the above structure are as follows:

[0022] (1) The cleaning component can continuously clean the glue without manual intervention, which can meet the needs of continuous production lines, reduce downtime, and based on its movement process, it can ensure that the glue in the glue brushing component is always in a "flowing state", thereby ensuring that the glue in the glue brushing component will not solidify and stick.

[0023] (2) The glue application component achieves multiple optimizations in terms of glue uniformity, material saving, operation stability and easy maintenance through symmetrical structure, glue recycling and directional flow design. Its core advantage lies in the deep integration of mechanical design and glue characteristics, which solves common problems in high viscosity glue coating (such as waste, unevenness and cleaning difficulty).

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.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a glue application device for solid wood core board, including a cleaning component 2 and a glue application component 3, wherein the cleaning component 2 is symmetrically arranged on both sides of the glue application component 3;

[0037] The cleaning component 2 is used to collect and gather the glue dripping from the glue application component 3;

[0038] The cleaning component 2 includes a touch rod 204 and a mounting base plate 210. Two sets of touch rods 204 are provided on both sides of the mounting base plate 210, and the two sets of touch rods 204 are axially symmetrical about the center of the cleaning component 2.

[0039] The adhesive application assembly 3 includes two sets of inclined base plates 303, and the two sets of inclined base plates 303 are arranged in a mirror image.

[0040] Furthermore, the cleaning component 2 also includes a base frame 201, a connecting column 202, a mounting plate 203, and a slide rail 205;

[0041] The basic frame 201 is rectangular. Each of the four ends of the basic frame 201 is provided with a set of connecting columns 202. A set of mounting plates 203 is fixed to the rear of any set of connecting columns 202. The other set of mounting plates 203 are axially symmetrical about the center point of the basic frame 201. A set of contact rods 204 is fixed to the front of each set of mounting plates 203. A set of slide rails 205 is fixed between the two sets of connecting columns 202.

[0042] like Figure 4 and Figure 5 As shown, the cleaning component 2 further includes a brush 206, a connecting shaft 207, and a sliding base 208;

[0043] The sliding base 208 is movably connected to the slide rail 205, the connecting shaft 207 is rotatably connected to the middle of the sliding base 208, and a set of brushes 206 are fixedly connected to the front of the connecting shaft 207.

[0044] Furthermore, the cleaning assembly 2 also includes a support column 209, a sliding rail 211, a sliding connecting seat 212, a spring 213, and a rotating connecting plate 214;

[0045] The sliding base 208 has multiple sets of support columns 209 fixedly connected to its rear. A mounting base plate 210 is fixedly connected to the rear of each set of support columns 209. The connecting shaft 207 passes through the mounting base plate 210 and can rotate within it. The mounting base plate 210 has a set of sliding rails 211 at its upper and lower parts. Each set of sliding rails 211 has a set of sliding connecting seats 212 movably connected inside it. The two sets of sliding connecting seats 212 are axially symmetrical about the connecting shaft 207 at 180°. The tail of the connecting shaft 207 has two sets of rotating connecting plates 214, which are also axially symmetrical about the connecting shaft 207 at 180°. A set of springs 213 is fixedly connected between each set of rotating connecting plates 214 and its front sliding connecting seat 212.

[0046] In this embodiment, the basic frame 201 is rectangular, and each of the four ends of the basic frame 201 is provided with a set of connecting columns 202. A set of slide rails 205 is fixed between the two sets of connecting columns 202. Since the sliding base 208 is movably connected to the slide rails 205, the sliding base 208 can perform reciprocating cyclic motion on the slide rails 205 through other parts or through a PLC (programmable logic controller).

[0047] The rear of the sliding base 208 is fixedly connected to multiple sets of support columns 209, and the rear of the multiple sets of support columns 209 is fixedly connected to the mounting base plate 210. As the sliding base 208 performs reciprocating cyclic movement on the slide rail 205, the support columns 209 and the mounting base plate 210 can also perform reciprocating cyclic movement with the sliding base 208.

[0048] Subsequently, a set of sliding rails 211 are provided on the upper and lower parts of the mounting base plate 210. Each set of sliding rails 211 is movably connected to a set of sliding connecting seats 212. When the mounting base plate 210 moves, the two sets of sliding rails 211 and sliding connecting seats 212 connected to it will also move accordingly.

[0049] The two sets of sliding connecting seats 212 are 180° axially symmetrical with the connecting shaft 207 as the center. The tail of the connecting shaft 207 is provided with two sets of rotating connecting plates 214, which are also 180° axially symmetrical with the connecting shaft 207 as the center. A set of springs 213 is fixedly connected between each set of rotating connecting plates 214 and the sliding connecting seat 212 in front of it. As the above movement proceeds, the other parts connected to the sliding connecting seat 212 will also perform reciprocating cyclic movement.

[0050] When the sliding base 208 moves the upper part of it to near the connecting column 202, because a set of mounting plates 203 are fixed to the rear of any set of connecting columns 202, and another set of mounting plates 203 are axially symmetrical about the center point of the base frame 201, and a set of touch rods 204 are fixed to the front of each set of mounting plates 203, the sliding connecting seat 212, which is on the same horizontal plane as the touch rods 204, will be touched by the touch rods 204.

[0051] Subsequently, the sliding connecting seat 212 moves on the sliding track 211 and drives the rotating connecting plate 214 to move through the spring 213 connected to it. However, the rotating connecting plate 214 is restricted by the connecting shaft 207 and cannot move horizontally. At this time, it can only make the connecting shaft 207 flip. The rotating connecting plate 214 on the other side of the connecting shaft 207 will drive the spring 213 to move, and through the spring 213 on the other side, it will make the sliding connecting seat 212 on the other side move on the sliding track 211. Finally, the elastic force of the springs 213 on both sides will reach a balance, and the connecting shaft 207 will stop rotating.

[0052] The front of the connecting shaft 207 is connected to a brush 206. As the sliding base 208 can reciprocate on the slide rail 205 and touch the touch rods 204 on both sides respectively, the connecting shaft 207 can drive the brush 206 to gradually move horizontally and flip within the space formed by the side sealing plate 305 and the inclined bottom plate 303.

[0053] In summary, the automatic reciprocating motion of the sliding base 208 on the slide rail 205, combined with the triggering of the brush flipping by the touch rod 204, realizes the "horizontal cleaning-flipping reset" cycle of the brush 206, so that the cleaning component 2 can continuously clean the glue without manual intervention, adapt to the needs of continuous production lines, reduce downtime, and based on the above motion process, it can ensure that the glue in the glue brushing component 3 is always in a "flowing state", thereby ensuring that the glue in the glue brushing component 3 will not solidify and stick.

[0054] like Figure 6 As shown, the adhesive application assembly 3 further includes a base 301, a motor 302, a power assembly 304, and a side sealing plate 305;

[0055] The base 301 consists of two sets, which are arranged in a mirror image. A set of motors 302 is fixedly connected to the upper part of any set of bases 301, and the power assembly 304 is located at the lower part of the motors 302. A set of side sealing plates 305 are fixedly connected to both sides of the two sets of bases 301, and a set of inclined bottom plates 303 is fixedly connected to the lower part of each set of side sealing plates 305.

[0056] Furthermore, the glue application assembly 3 also includes a brush movement port 306, an auxiliary roller 307, a pouring port 308, an upper roller 309, and a lower roller 310;

[0057] Each set of side sealing plates 305 has a brush movable opening 306 in the middle. The brush movable opening 306 penetrates the side sealing plate 305 through a cutting process. The upper roller 309 is rotatably connected to the upper part of the base 301. The lower roller 310 is rotatably connected to the lower part of the upper roller 309. Two sets of auxiliary rollers 307 are rotatably connected to the bottom of the lower roller 310. Each set of inclined bottom plates 303 has a tilting opening 308 in the center. The tilting opening 308 penetrates the inclined bottom plate 303 through a cutting process.

[0058] Furthermore, the two sets of inclined base plates 303 are mirror images of each other with the central axis of the upper roller 309 as the reference point, and the part of the inclined base plate 303 near the central axis of the upper roller 309 is the highest point.

[0059] Furthermore, the connecting shaft 207 passes through the brush movable opening 306, and the brush 206 is located inside the space formed by the side sealing plate 305 and the inclined bottom plate 303.

[0060] In this embodiment, since the two sets of bases 301 are arranged in a mirror image and a set of motors 302 are fixedly connected to the upper part of any set of bases 301, the upper roller 309 can be fixed between the two sets of bases 301 and connected, so that when the motor 302 rotates, it can drive the upper roller 309 to rotate.

[0061] The lower roller 310 is rotatably connected to the lower part of the upper roller 309, and there is a certain gap between the upper roller 309 and the lower roller 310 to allow the core plate 1 to pass through. When the upper roller 309 rotates, it gradually conveys the core plate 1 and applies glue to the surfaces of the upper roller 309 and the lower roller 310. As the upper roller 309 and the lower roller 310 rotate, the two sides of the core plate 1 will be coated with glue for bonding.

[0062] Excess glue on the upper roller 309 and lower roller 310 will gradually drip off. Because the bottom of the lower roller 310 is rotatably connected to two sets of auxiliary rollers 307, the glue will first drip onto the auxiliary rollers 307. The auxiliary rollers 307 are connected to the power component 304, and the power component 304 is connected to the motor 302. When the motor 302 rotates, it will drive the power component 304 to rotate, and the power component 304 will drive the auxiliary rollers 307 to rotate.

[0063] As the auxiliary roller 307 rotates, the glue dripping onto it gradually adheres to its surface. As the auxiliary roller 307 comes into contact with the lower roller 310, the glue dripping onto the auxiliary roller 307 re-adheres onto the lower roller 310, ensuring the uniformity of the glue on the surface of the lower roller 310.

[0064] Both sides of the two sets of bases 301 are fixed with a set of side sealing plates 305. Each set of side sealing plates 305 is fixed with a set of inclined bottom plates 303 at the bottom, so that the side sealing plate 305 on one side and the inclined bottom plate 303 form a sealed space, and the sealed space can store the glue dripping from the auxiliary roller 307.

[0065] Furthermore, since the two sets of inclined base plates 303 are mirror images of the upper roller 309 with the central axis as the reference point, and the part of the inclined base plate 303 near the central axis of the upper roller 309 is the highest point, the glue dripping from the auxiliary roller 307 will slide to both sides from the part near the central axis of the upper roller 309 due to gravity.

[0066] Because the glue itself has very high viscosity, the dripping process is relatively slow. The connecting shaft 207 passes through the brush movement port 306. The brush 206 is located inside the space formed by the side sealing plate 305 and the inclined bottom plate 303. At this time, the brush 206 at the front of the cleaning component 2 will reciprocate inside the space formed by the side sealing plate 305 and the inclined bottom plate 303, and bring the glue inside the space closer to the pouring port 308, so that excess glue can be collected through the pouring port 308.

[0067] This adhesive application assembly 3 achieves multiple optimizations in terms of coating uniformity, material conservation, operational stability, and ease of maintenance through its symmetrical structure, adhesive recycling, and directional flow design. Its core advantage lies in the deep integration of mechanical design with adhesive properties, solving common problems in high-viscosity adhesive coating (such as waste, unevenness, and cleaning difficulties). Specific advantages are as follows:

[0068] First, considering the strong viscosity of the adhesive, the slope design of the inclined base plate 303 balances gravity guidance and adhesive flow resistance, preventing adhesive residue. Then, through the contact between the auxiliary roller 307 and the lower roller 310, the dripping adhesive is brought back to the surface of the lower roller 310. The power component 304 and the motor 302 are linked to achieve adhesive recycling, reducing material waste. Subsequently, the rotation of the auxiliary roller 307 ensures that the adhesive is evenly distributed on the surface of the lower roller 310, avoiding problems such as glue breakage or uneven thickness during the application process. Finally, the mirror tilt structure of the inclined base plate 303, combined with the pouring port 308, allows the adhesive to naturally collect at the designated collection point, facilitating centralized recycling or reuse.
