Description

Technical Field

[0001] The present invention relates to the field of wooden square production equipment, and specifically to a rapid glue injection device for composite wooden square production. Background Art

[0002] A composite wooden square is a new type of building material different from traditional building wooden squares. The composite wooden square has characteristics such as moisture resistance, corrosion resistance, antifungal, insect and termite prevention, and mildew prevention. The length of the composite wooden square can be arbitrarily customized according to needs. The composite wooden square is a substitute for traditional wooden squares and an optimized product of other formwork support rods. It can not only avoid material waste and environmental pollution of traditional wooden squares, but also save the use cost and improve the project quality.

[0003] When making a composite wooden square, glue needs to be coated on the bonding surface of the boards, and then the boards are pressed together. In the prior art, a glue injection machine is usually used to complete this step. However, when the existing glue injection machine applies glue to the boards, it cannot evenly coat the glue on the surface of the boards, resulting in a decrease in the adhesion degree of the boards, thereby affecting the product quality.

[0004] In view of the above problems, the Chinese invention patent with the authorization announcement number CN101862723B proposes a glue injection machine for coating glue on the surface of a substrate. In this patent, during the continuous rotation of the glue application roller, the concave grooves of the knurled roller are filled with glue and there is no excess glue on the glue application roller, so that the glue can be evenly coated on the surface of the board.

[0005] However, the above patent and the traditional glue injection machine still cannot perform the glue application operation on the glue application surfaces of the boards required for making composite wooden squares at the same time, so that the boards need to be glued sequentially, reducing the production efficiency. Moreover, the boards that have been glued first need to wait for the other boards to be glued before starting the assembly. During this process, the glue on the surface of the boards is prone to solidification, resulting in a decrease in the adhesion degree between the boards and affecting the product quality. In addition, in the prior art, the glued boards are usually stacked together manually, and then the pressed boards are cut into regular shapes. The manual stacking method is likely to make the boards uneven, so that all four sides of the boards need to be cut during cutting, resulting in waste of the boards and increasing the production cost. Summary of the Invention

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rapid glue injection device for composite wooden square production, including a bottom plate, an outer shell is arranged on the upper part of the bottom plate, and a glue application component for simultaneously applying glue to the boards required for making composite wooden squares is arranged in the middle of the inner side of the outer shell, and an assembly component for combining and pressing the boards after glue application is arranged in the front part of the inner side of the outer shell.

[0007] The glue - applying component includes three glue - applying racks arranged in sequence from front to back inside the outer shell. A number of glue - applying rollers are rotatably arranged at equal intervals up and down inside the glue - applying racks. A glue - applying brush is arranged on the outer side of the glue - applying rollers. A glue storage tank is arranged at the position corresponding to the glue - applying rollers at the rear side of the outer shell. A glue - discharging brush is arranged at the front part of the glue storage tank. Limiting rollers are rotatably arranged between the lower part of the front - and - rear glue - applying racks and the upper part of the middle glue - applying rack. The limiting rollers are used for limiting and fixing the plates that need to be coated on one side at the top and bottom positions.

[0008] The assembling component includes an assembling rack slidably arranged left and right at the front part of the outer shell. The assembling rack is arranged at equal intervals up and down corresponding to the positions of the glue - applying rollers. An assembling hydraulic cylinder for pressing the plates together is arranged at the upper side of the front part of the outer shell. An alignment conveyor belt is arranged at the upper side inside the assembling rack. Protrusions for pushing the plates to the left are spirally arranged on the alignment conveyor belt. A blocking plate is slidably arranged left and right at the right side of the outer shell. The blocking plate is arranged at equal intervals up and down corresponding to the position of the assembling rack. A blocking spring is arranged between the right side of the blocking plate and the outer shell. A pushing member is slidably arranged left and right at the lower - right side of the outer shell. A pushing spring is arranged between the right side of the pushing member and the outer shell.

[0009] A blanking hydraulic cylinder is installed on the upper part of the bottom plate. A blanking frame is installed on the upper part of the blanking hydraulic cylinder. A blanking conveyor belt is arranged inside the blanking frame.

[0010] During specific operation, first, rotate the glue - applying rollers so that the glue - applying brush and the glue - discharging brush are in contact with each other, and the glue inside the glue storage tank adheres to the outer side of the glue - applying rollers. After the glue - applying rollers rotate for a period of time, through the mutual contact of the glue - applying brushes of the adjacent left - and - right glue - applying rollers, the glue evenly adheres to the outer sides of all the glue - applying rollers. At this time, place the required plates from the rear side of the outer shell into the inside of the glue - applying racks, so that the plates are placed between the glue - applying rollers. While the glue - applying rollers drive the plates to move forward, the glue is evenly brushed on the surfaces of the plates. When the plates move to the corresponding assembling racks, the rotating alignment conveyor belt pushes the plates to move until they are tightly pressed against the front side and the left side of the outer shell. The bottom plates are synchronously pressed tightly through the blanking conveyor belt and the pushing of the pushing member. Move the assembling racks leftward one by one from top to bottom. The blocking plates synchronously extend leftward to support the right sides of the plates. After the assembling racks move until they are out of contact with the plates, the left sides of the plates first fall on the left sides of the lower - lying plates, so that the plates are stacked together in sequence with left - alignment and front - alignment during the falling process. Extend the assembling hydraulic cylinder to press the stacked plates tightly. Finally, lower the blanking frame to move out the assembled wooden squares.

[0011] As a preferred technical solution of the present invention, feeding plates are arranged at equal intervals up and down at the rear side of the outer shell.

[0012] As a preferred technical solution of the present invention, the glue applicator racks at the front and rear positions are fixedly installed inside the housing, and the glue applicator rack at the middle position is slidably arranged up and down inside the housing. A threaded rod is rotatably arranged on the upper part of the glue applicator rack in the middle, and the threaded rod penetrates upward to the upper part of the housing and is in threaded cooperation with it.

[0013] As a preferred technical solution of the present invention, the glue applicator roller and the limiting roller arranged on the same glue applicator rack are connected together by a belt on the left side. A glue application motor is installed on the upper part of the housing, a driving gear is rotatably arranged on the right side of the housing, a belt pulley is installed on the right side of the limiting roller at the middle position, and the output shaft of the glue application motor is connected to the belt pulley and the driving gear through a belt. A driven gear is rotatably installed on the right side of the glue applicator roller on the upper side of the glue applicator racks at the front and rear positions, and the driven gear meshes with the driving gear.

[0014] As a preferred technical solution of the present invention, a slope is arranged at the rear part of the pushing member.

[0015] As a preferred technical solution of the present invention, arc surfaces are arranged on both the upper and lower sides of the left side of the blocking plate.

[0016] As a preferred technical solution of the present invention, a rack is arranged at the front part of the assembly frame, a moving motor is arranged on the left side of the front part of the housing, moving gears are equidistantly sleeved on the output shaft of the moving motor, a dial rod is arranged at the lower right part of the upper assembly frame, and a dial plate is arranged at the upper left part of the lower assembly frame.

[0017] The beneficial effects of the present invention are as follows:

[0018] First, the present invention uses the glue applicator rollers in the three glue applicator racks to apply glue to the glue application surfaces of the plates simultaneously, thus improving the production efficiency; and the plates after glue application can immediately enter the interior of the assembly components for assembly, greatly reducing the waiting time of the plates, thereby ensuring the adhesion degree between the plates and ensuring the product quality.

[0019] Second, the present invention uses the alignment conveyor belt to push and press the upper plate against the left side and the front side of the housing, and uses the blanking conveyor belt and the pushing member to push the bottom plate to press against the left side and the front side of the housing, so that the left side and the front side of all the plates are in the same plane, so that the rear side and the right side of the cut wooden square can be regular, avoiding waste of the plates and saving the production cost.

[0020] Third, when the assembly frame moves to the left, the present invention uses the blocking plate to automatically extend and support the right side of the plate, so that the left side of the plate falls first when stacking the plates, and the plate moves to the left during the falling process, so as to facilitate the alignment of the left side of the plate.

[0021] IV. The glue - applying rack that adjusts the middle position in the present invention enables the glue - applying roller and the limiting roller to clamp plates with different thicknesses for glue - applying, increasing the applicability of the present invention.

[0022] V. In the present invention, all the glue - applying rollers and limiting rollers are connected by belts and gears to rotate synchronously, enabling the glue - applying operation of the plates to be carried out synchronously, reducing the waiting time of the plates, and ensuring the adhesion ability of the glue.

[0032] The embodiments of the present invention will be described in detail below. The following described embodiments are exemplary and are only used to explain the present invention, and cannot be understood as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in the field or according to the product instructions.

[0033] Refer to Figure 1 and Figure 2 A rapid glue injection device for the production of composite wooden square timbers, comprising a bottom plate. An outer shell 1 is arranged on the upper part of the bottom plate. A glue coating component 2 for simultaneously coating the required plates for making composite wooden square timbers is arranged in the middle of the inner side of the outer shell 1. An assembly component 3 for combining and compressing the plates after glue coating is arranged in the front part of the inner side of the outer shell 1. When processing the plates, first, the plates are fed into the inside of the glue coating component 2 from the rear of the outer shell 1. The glue coating component 2 performs a glue coating operation on the surfaces of the plates that need to be coated simultaneously. Then, the present invention automatically feeds the plates after glue coating into the inside of the assembly component 3. The assembly component 3 stacks and levels the plates and then compresses and assembles them to complete the processing of the wooden square timbers.

[0034] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The glue coating component 2 includes three glue coating racks 21 arranged in the outer shell 1 from front to back in sequence. The glue coating racks 21 at the front and rear positions are fixedly installed inside the outer shell 1. The glue coating rack 21 at the middle position is slidably arranged up and down inside the outer shell 1. A threaded rod 211 is rotatably arranged on the upper part of the glue coating rack 21 at the middle position. The threaded rod 211 penetrates upward to the upper part of the outer shell 1 and is in threaded cooperation with it. A plurality of glue coating rollers 22 are rotatably arranged at equal intervals up and down inside the glue coating rack 21. A glue coating brush 221 is arranged on the outer side of the glue coating roller 22. A glue storage tank 23 is arranged at the corresponding position of the glue coating roller 22 on the rear side of the outer shell 1. A glue outlet brush 231 is arranged at the front part of the glue storage tank 23. A limiting roller 24 is rotatably arranged between the lower part of the glue coating racks 21 at the front and rear positions and the upper part of the glue coating rack 21 at the middle position. The limiting roller 24 is used for limiting and fixing the plates that need to be coated on one side at the top and bottom positions. When processing the plates, first, rotate the threaded rod 211. The threaded rod 211 drives the glue coating rack 21 at the middle position to move up and down to a suitable position, so that the limiting roller 24 at the upper part can press the plate downward against the upper part of the glue coating roller 22, so that the surface of the plate that needs to be coated is in close contact with the glue coating roller 22. Then, rotate the glue coating roller 22 so that the glue coating brush 221 and the glue outlet brush 231 are in contact with each other, and the glue inside the glue storage tank 23 is adhered to the outer side of the glue coating roller 22. After the glue coating roller 22 rotates for a period of time, through the mutual contact of the glue coating brushes 221 of the adjacent glue coating rollers 22 on the left and right, the glue is evenly adhered to the outer sides of all the glue coating rollers 22.

[0035] Refer to Figure 1 The rear side of the outer shell 1 is provided with feeding plates 11 at equal intervals up and down; place the plates to be processed on the feeding plates 11 and then push them into the inside of the glue coating rack 21 simultaneously.

[0036] Refer to Figure 4 and Figure 5, the left sides of the glue - applying roller 22 and the limiting roller 24 arranged on the same glue - applying rack 21 are connected together by a belt. A glue - applying motor 25 is installed on the upper part of the housing 1. A driving gear 26 is rotatably arranged on the right side of the housing 1. A belt pulley 241 is installed on the right side of the limiting roller 24 at the middle position. The output shaft of the glue - applying motor 25 is connected to the belt pulley 241 and the driving gear 26 through a belt. A driven gear 222 is rotatably installed on the right side of the glue - applying roller 22 on the upper side of the front - and - rear glue - applying racks 21. The driven gear 222 meshes with the driving gear 26. When the glue - applying motor 25 is started, it drives the belt pulley 241 and the driving gear 26 to rotate. The belt pulley 241 drives the limiting roller 24 at the middle position to rotate. The limiting roller 24 at the middle position drives the glue - applying roller 22 at the middle to rotate. At the same time, the driving gear 26 drives the driven gear 222 to rotate, and the driven gear 222 drives the glue - applying roller 22 at the corresponding position to rotate, thereby driving all the glue - applying rollers 22 and the limiting rollers 24 to rotate, so that the pressed plate can be glued while being transported forward.

[0037] Specifically, when the plate needs to be processed, first, adjust the middle glue - applying rack 21 to a position where the surface of the plate to be glued can be in close contact with the glue - applying roller 22. Then start the glue - applying motor 25 to drive all the glue - applying rollers 22 and the limiting rollers 24 to rotate synchronously, so that the glue - applying roller 22 contacts the glue - discharging brush 231 through the glue - applying brush 221, and adheres the glue inside the glue storage tank 23 to the outer side of the glue - applying roller 22. After that, place the plate to be processed on the feeding plate 11 and push it into the glue - applying rack 21 at the same time. The rotation of the glue - applying roller 22 and the limiting roller 24 drives the plate to be transported forward simultaneously and evenly coats the glue on the plate.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7, the assembly component 3 includes an assembly frame 31 slidably arranged left and right at the front of the housing 1. The assembly frames 31 are arranged at equal intervals up and down corresponding to the position of the glue application roller 22. An alignment conveyor belt 33 is arranged on the upper side inside the assembly frame 31. Protrusions for pushing the plate to the left are spirally arranged on the alignment conveyor belt 33. A pushing member 36 is slidably arranged left and right on the right side of the lower part of the housing 1. A pushing spring is arranged between the right side of the pushing member 36 and the housing 1. A blanking hydraulic cylinder 4 is installed on the upper part of the bottom plate. A blanking frame 41 is installed on the upper part of the blanking hydraulic cylinder 4. A blanking conveyor belt 42 is arranged inside the blanking frame 41; after the glue application component 2 finishes applying glue to the plate, it transports the plate to the assembly frame 31 at the same time. Start the alignment conveyor belt 33 to rotate and drive the plate to move forward until it abuts against the front wall of the housing 1. When the alignment conveyor belt 33 rotates, the spirally arranged protrusions can push the plate to the left to abut against the left wall of the housing 1. The lowermost plate abuts against the front wall of the housing 1 through the blanking conveyor belt 42. At the same time, the pushing member 36 pushes the plate to the left to abut against the left wall of the housing 1 under the action of the elastic force of the pushing spring, so that the left sides and the front sides of all the plates are flush.

[0039] Refer to Figure 2 and Figure 7 , a slope is arranged at the rear of the pushing member 36. When the blanking conveyor belt 42 drives the plate to move forward, the right side of the plate contacts the slope of the pushing member 36 and pushes the pushing member 36 to the right. The elastic force of the pushing member 36 pushes the plate to the left until it abuts against the left wall of the housing 1.

[0040] Refer to Figure 2 and Figure 3, a rack 311 is provided at the front of the assembly frame 31, a moving motor 35 is provided on the left side of the front of the housing 1, moving gears 351 are sleeved on the output shaft of the moving motor 35 at equal intervals, and lower right parts of the right sides of the upper assembly frames 31 are provided with lever rods 312, and upper left parts of the left sides of the lower assembly frames 31 are provided with dial plates 313. A blocking plate 34 is slidably arranged left and right on the right side of the housing 1, and the blocking plate 34 is arranged at equal intervals up and down corresponding to the position of the assembly frame 31. A blocking spring is arranged between the right side of the blocking plate 34 and the housing 1. In the initial state, the rack 311 at the uppermost part is engaged with the moving gear 351 at the corresponding position, and the remaining racks 311 are located on the right side of the moving gears 351 at the corresponding positions. When all the plates are moved onto the assembly frames 31 at the corresponding positions, the moving motor 35 is started to drive the moving gear 351 to rotate. The moving gear 351 at the uppermost part drives the rack 311 at the corresponding position to move leftward. The rack 311 at the uppermost part drives the assembly frame 31 at the corresponding position to move leftward. At this time, the uppermost blocking plate 34 synchronously moves leftward to the lower part of the plate at the corresponding position to support the right end of the plate, so that after the assembly frame 31 moves to be disengaged from the plate, the left side of the plate first falls on the left side of the lower plate, thereby ensuring that the left sides are flush when the plates are stacked. When the assembly frame 31 drives the lever rod 312 to move leftward until it contacts the dial plate 313 of the lower assembly frame 31, the lower assembly frame 31 is pushed leftward to make the lower rack 311 engaged with the moving gear 351 at the corresponding position. Then, according to the above principle, all the plates are stacked together with their left ends and front ends aligned.

[0041] Refer to Figure 1 and Figure 2 , an assembly hydraulic cylinder 32 for pressing the plates together is provided on the upper side of the front of the housing 1; the piston rod of the assembly hydraulic cylinder 32 is extended to press the stacked plates tightly.

[0042] Continue to refer to Figure 1 and Figure 2 , arc surfaces are provided on both the upper and lower surfaces of the left side of the blocking plate 34; when the assembly hydraulic cylinder 32 moves downward and returns to the initial position, it contacts the arc surface of the blocking plate 34 and pushes the blocking plate 34 to the right side to prevent the blocking plate 34 from hindering the movement of the assembly hydraulic cylinder 32.

[0043] Specifically, after the plate is coated with glue, start the alignment conveyor belt 33 to rotate and drive the upper plate to move forward until it abuts against the front wall and the left wall of the housing 1. The lowermost plate is abutted against the front wall and the left wall of the housing 1 by the pushing of the blanking conveyor belt 42 and the pusher 36, so that the left sides and the front sides of all the plates are flush. Then, start the moving motor 35 to move the assembly frame 31 leftward successively from top to bottom. The corresponding baffle 34 extends leftward synchronously to support the right side of the plate. After the assembly frame 31 moves to be out of contact with the plate, the left side of the plate first falls on the left side of the lower plate, so that the plates are stacked together in a left-aligned and front-aligned manner by falling. Then, extend the assembly hydraulic cylinder 32 to compact the stacked plates. Finally, lower the blanking hydraulic cylinder 4 to drive the blanking frame 41 to take the assembled wooden square out of the housing 1, and move the wooden square forward through the blanking conveyor belt 42, thus completing the blanking.

[0044] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
