Description

Technical Field

[0001] This invention relates to the field of plywood processing technology, specifically to a pressing and processing equipment for producing curved plywood. Background Technology

[0002] Before hot-pressing curved plywood, multiple layers of boards need to be stacked sequentially. When stacking, the edges of the boards need to be aligned and the surface of the boards needs to be cleaned. Then, glue needs to be applied to the surface of the boards. If the surface of the boards is dirty, it will affect the adhesion between the boards.

[0003] For example, a pressing device for plywood production and processing, as disclosed in announcement number CN219311521U, includes a worktable and a placement plate set on the worktable for placing plywood. A spring is fixed between the worktable and the placement plate to drive the placement plate to rotate. A steering block is symmetrically arranged on the worktable, and connecting ropes passing through the steering blocks are fixed on both sides of the placement plate. This device, by setting a spring between the worktable and the placement plate to drive the placement plate to rotate, allows the processed plywood to slide down along the inclined surface of the placement plate, thereby achieving automated unloading. Simultaneously, the support plate, in conjunction with the device, supports the placement plate, improving the stability of the placement plate during the pressing process and ensuring the alignment of the two sides of the plywood, preventing positional shifts.

[0004] However, during the plywood gluing process, it is necessary to control the distance between the gluing roller and the board to ensure uniform gluing and compliance with process requirements. When applying glue evenly to curved or twisted plywood, traditional flat gluing equipment cannot guarantee uniform glue distribution on the curved surface. Therefore, an adhesive with moderate fluidity should be selected, and the amount of glue applied should be strictly controlled. The glue layer thickness should be controlled between 0.08 and 0.15 mm. An excessively thick glue layer will increase curing shrinkage stress and exacerbate deformation. For porous substrates, an excessively thin glue layer may affect the bonding effect of the board and reduce the quality of plywood pressing. Summary of the Invention

[0005] The purpose of this invention is to provide a pressing and processing equipment for the production of curved plywood, so as to solve the problem that traditional flat gluing equipment cannot guarantee the uniform distribution of glue on the curved surface for curved and twisted plywood, which reduces the quality of plywood pressing and processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressing and processing equipment for producing arc-shaped plywood, comprising a column, an oil pump, an arc-shaped slide rail and uniformly arranged placement plates, wherein a V-shaped groove is provided on the top of the placement plates; Also includes: The outer side of the placement plate is uniformly provided with clamping assemblies, the top of the arc-shaped slide rail is slidably mounted with a bottom plate, the top of the bottom plate is slidably mounted with an upper plate, and the top of the upper plate is provided with an adhesive applicator. The adhesive application assembly includes a vertical plate fixedly connected to a top plate, a side plate slidably mounted on one side of the vertical plate, an mounting plate rotatably mounted on the side of the side plate away from the vertical plate, an adhesive application roller vertically rotatably connected inside the mounting plate, a pump body fixedly mounted on the top of the upper plate, a discharge pipe connected to the outlet end of the pump body, and a connecting pipe fixedly connected to the end of the discharge pipe away from the pump body.

[0007] Preferably, a glue tank is fixedly connected to one side of the vertical plate, and a feeding port is fixedly installed on the top of the glue tank. A lead screw is rotatably connected to the other side of the vertical plate, and a sleeve is threaded to the outer side of the lead screw. The sleeve is fixedly connected to the side plate. A fixed plate is fixedly connected to the outer side of the lead screw. A fixed rod is also fixedly connected to one side of the vertical plate. A sliding sleeve is slidably connected to the outer side of the fixed rod. The sliding sleeve is fixedly connected to the side plate. A spring is sleeved on the outer side of the fixed rod. The two ends of the spring are fixedly connected to the vertical plate and the sliding sleeve, respectively. A feed pipe is connected to the outlet end of the pump body. The feed pipe is connected to the glue tank. A lower plate is fixedly connected between the connecting pipe and the mounting plate.

[0008] By adopting the above technical solution, the cooperation of the arc-shaped guide rail and hydraulic rod facilitates the sliding of the arc-shaped plate and maintains a stable fit with the arc-shaped plate, achieving stable glue application. At the same time, as the glue application roller rotates, it is easy to intermittently replenish the material on the outside of the glue application roller and drive the smearing rollers on both sides to swing and smear evenly. This avoids excessive material replenishment by the glue application roller, which would increase the curing shrinkage stress, and can maintain stability and uniformity, thereby reducing the deformation of the arc-shaped plate in the later stage and improving the quality of the pressing process.

[0009] Preferably, the connecting pipe has two symmetrically formed inner grooves inside, a sealing sleeve is slidably connected to the outside of the connecting pipe, a second spring is sleeved on the outside of the connecting pipe, the two ends of the second spring are fixedly connected to the sealing sleeve and the lower plate respectively, a slider is fixedly connected inside the sealing sleeve, the slider is slidably connected to the inner groove, and an inner plate is vertically fixedly installed inside the mounting plate.

[0010] By adopting the above technical solution, the coating roller drives the lower push rod to rotate, and the lower push rod will intermittently squeeze the trapezoidal block. The trapezoidal block drives the sealing sleeve to slide, and the sealing sleeve drives the slider and sliding plate to slide. The slider slides inside the inner groove, which facilitates the subsequent replenishment of the coating roller.

[0011] Preferably, a sliding plate is fixedly connected to the inner side of the slider, and a through hole is opened inside the sliding plate. A fixing plate is fixedly connected to the inside of the connecting tube. The fixing plate is located on the side of the through hole away from the vertical plate. A material hole is fixedly connected inside the fixing plate. The through hole and the material hole are staggered. A trapezoidal block is fixedly connected to the top of the first spring. A push rod is fixedly connected to the bottom end of the glue roller through the mounting plate.

[0012] By adopting the above technical solution, when the sliding plate and the fixed plate separate, the glue flows from the through hole into the material hole, and then is replenished into the inner plate through the auxiliary tube, which facilitates intermittent replenishment of the glue coating roller.

[0013] Preferably, an auxiliary pipe is fixedly connected to the end of the connecting pipe away from the discharge pipe, the auxiliary pipe is connected to the inner plate, the inner plate has discharge ports evenly opened on the side near the coating roller, the top of the coating roller is fixedly connected to an upper push rod through the mounting plate, and side rods are fixedly connected to both sides of the mounting plate.

[0014] By adopting the above technical solution, the evenly spaced discharge ports facilitate the uniform replenishment of material to the coating roller.

[0015] Preferably, a connecting plate is rotatably connected to the outer side of the side rod, a spring is fixedly connected between the connecting plate and the mounting plate, a mounting frame is fixedly connected to one side of the connecting plate, a smoothing roller is rotatably connected inside the mounting frame, and a bending rod is fixedly connected to the top of the mounting frame.

[0016] By adopting the above technical solution, the coating roller will also drive the upper push rod to rotate, the upper push rod will squeeze the bending rod, the bending rod will drive the mounting frame to rotate, the connecting plate will rotate around the side rod as the axis, and the connecting plate will stretch the third spring. When the upper push rod and the bending rod are separated, the elastic force of the third spring will drive the connecting plate and the mounting frame to reset, so that the spreading roller will swing back and forth and spread evenly.

[0017] Preferably, the clamp assembly includes a first clamp plate, a second clamp plate, and a pressure plate. Two bonding plates are fixedly connected to one side of the bottom of the first clamp plate. The bonding plates are fixed to the second clamp plate by bolts. Slots are evenly provided inside the first clamp plate and the bonding plates.

[0018] By adopting the above technical solution, clamp plate one is attached to one side of the arc plate, clamp plate two is attached to the other side of the arc plate, clamp plate two is fixed with bolts, and then pressure plate is put on the outside of clamp plate one and clamp plate two to facilitate pressing and fixing the stacked arc plates.

[0019] Preferably, the pressure plate has a sliding groove inside, and the clamping plate and the bonding plate are slidably connected to the sliding groove. The slot has an insert block and a wedge block slidably connected inside.

[0020] By adopting the above technical solution, clamping plates one and two are kept in the slide groove, and then the insert and wedge are inserted into the nearest slot above the pressure plate, so that the insert presses the pressure plate, thereby pressing and fixing the stacked arc plates.

[0021] Preferably, a hydraulic rod is fixedly installed on the top of the base plate, and the telescopic end of the hydraulic rod is fixedly connected to the top plate. A vertical rod is fixedly connected to the bottom of the upper plate, and the vertical rod is slidably connected to the top plate. A spring four is sleeved on the outside of the vertical rod, and the two ends of the spring four are fixedly connected to the top plate and the upper plate, respectively.

[0022] By adopting the above technical solution, the hydraulic rod drives the top plate to rise and fall, which can be adjusted over a wide range. The upper plate can slide inside the top plate through the vertical rod. The spring four works in conjunction with the rise and fall of the upper plate to stretch or contract accordingly, which is convenient for adapting to the vertical height of the curved plate and allowing for autonomous small-range adjustment.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up an adhesive application assembly, the cooperation of the arc-shaped guide rail and hydraulic rod facilitates the sliding of the curved plate along its trajectory and maintains a stable fit with the curved plate, achieving stable adhesive application. Simultaneously, as the adhesive application roller rotates, it facilitates intermittent replenishment of material on the outer side of the roller and drives the smearing rollers on both sides to oscillate and spread the adhesive evenly. This avoids excessive material replenishment from the adhesive application roller, which increases curing shrinkage stress, and maintains stable and uniform adhesive application, thereby reducing subsequent deformation of the curved plate and improving the quality of the pressing process. By setting up a positioning assembly, the curved plates are stacked on a placement plate by hoisting and pressed by an oil pump. The stacked curved plates are fixed by uniformly arranged clamping plates one, two, and pressure plates, further assisting in achieving stable pressing of the curved plates. The specific details are as follows: 1. By setting up the glue application assembly, the hydraulic rod drives the top plate to rise and fall, allowing for a wide range of height adjustment. The upper plate can slide inside the top plate via a vertical rod. Spring 4, in conjunction with the rising and falling of the upper plate, stretches or contracts accordingly, facilitating independent small-range adjustment of the vertical height to accommodate the curved plate. The operator rotates the fixed plate, which drives the lead screw to rotate. The lead screw rotation moves the sleeve and side plate, which in turn moves the sliding sleeve. The sliding sleeve slides on the fixed rod and stretches spring 1, thereby adjusting the distance between the glue application roller and the curved plate, facilitating subsequent glue application operations. The mounting plate is rotatably connected to the side plate, and an auxiliary spring is set between the mounting plate and the side plate to facilitate sliding on the curved surface of the curved plate. The pump body draws glue from inside the glue tank through the feed pipe. The glue enters the connecting pipe and is applied as the glue application roller rolls. The lower push rod rotates, intermittently pressing the trapezoidal block. The trapezoidal block causes the sealing sleeve to slide, which in turn causes the slider and sliding plate to slide. The slider slides inside the inner groove, causing the sliding plate to separate from the fixed plate. Glue flows from the through hole into the material hole and then from the auxiliary tube into the inner plate, facilitating intermittent replenishment of the coating roller. The coating roller also drives the upper push rod to rotate, pressing the bending rod. The bending rod causes the mounting bracket to rotate, and the connecting plate rotates around the side rod as an axis. The connecting plate also stretches the third spring. When the upper push rod separates from the bending rod, the elasticity of the third spring causes the connecting plate and mounting bracket to reset, causing the sizing roller to oscillate back and forth and sizing evenly. This avoids excessive replenishment of the coating roller, which increases curing shrinkage stress, and maintains stable and uniform coating, thereby reducing subsequent deformation of the curved plate and improving the quality of the pressing process. 2. By setting up a clamping assembly, the hoisting device installed on the column stacks the arc-shaped plates in the V-shaped groove on top of the placement plate. After applying glue, the operator uses an oil pump to press and fix the stacked arc-shaped plates. Then, clamp plate one is attached to one side of the arc-shaped plate, and clamp plate two is attached to the other side of the arc-shaped plate. Clamp plate one and clamp plate two are fixed with bolts. Then, the pressure plate is placed on the outside of clamp plate one and clamp plate two, so that clamp plate one and clamp plate two are located in the sliding groove. Then, the insert block and wedge block are inserted into the nearest slot above the pressure plate, so that the insert block presses the pressure plate, thereby pressing and fixing the stacked arc-shaped plates, improving the positioning stability and reducing the pressing deviation.

The fixing rod 78 and the sliding sleeve 79 limit the side plate 77 and are used to maintain the stable lateral movement adjustment of the side plate 77.

[0032] The sliding sleeve 79 is fixedly connected to the side plate 77. A spring 710 is sleeved on the outside of the fixing rod 78. The two ends of the spring 710 are fixedly connected to the vertical plate 71 and the sliding sleeve 79, respectively. The outlet end of the pump body 711 is connected to the feed pipe 712. The feed pipe 712 is connected to the glue tank 72. The connecting pipe 716 is fixedly connected to the mounting plate 714 with the lower plate 717.

[0033] The connecting pipe 716 has two symmetrically formed inner grooves 718. A sealing sleeve 719 is slidably connected to the outside of the connecting pipe 716. A sealing layer is provided between the sealing sleeve 719 and the connecting pipe 716 to improve the sealing performance. A spring 720 is sleeved on the outside of the connecting pipe 716. The two ends of the spring 720 are fixedly connected to the sealing sleeve 719 and the lower plate 717, respectively. A slider 721 is fixedly connected inside the sealing sleeve 719. The slider 721 is slidably connected to the inner grooves 718. An inner plate 729 is vertically fixedly installed inside the mounting plate 714.

[0034] A sliding plate 722 is fixedly connected to the inner side of the slider 721. A through hole 723 is opened inside the sliding plate 722. A fixing plate 724 is fixedly connected inside the connecting tube 716. The fixing plate 724 is located on the side of the through hole 723 away from the vertical plate 71. A material hole 725 is fixedly connected inside the fixing plate 724. The through hole 723 and the material hole 725 are staggered. A trapezoidal block 726 is fixedly connected to the top of the spring 710. A lower push rod 727 is fixedly connected to the bottom end of the glue roller 715 through the mounting plate 714.

[0035] An auxiliary pipe 728 is fixedly connected to the end of the connecting pipe 716 away from the discharge pipe 713. The auxiliary pipe 728 is connected to the inner plate 729. The inner plate 729 has discharge ports 730 evenly distributed on the side near the coating roller 715. Glue flows into the material hole 725 from the through hole 723 and is then replenished into the inner plate 729 through the auxiliary pipe 728, which facilitates replenishment of the coating roller 715. The top of the coating roller 715 is fixedly connected to the upper push rod 731 through the mounting plate 714. Side rods 732 are fixedly connected to both sides of the mounting plate 714.

[0036] A connecting plate 733 is rotatably connected to the outer side of the side rod 732. A spring 734 is fixedly connected between the connecting plate 733 and the mounting plate 714.

A bending rod 737 is fixedly connected to the top of the mounting bracket 735.

[0037] Example 1: As Figure 3 - Figure 11As shown, the hydraulic rod 8 drives the top plate 9 to rise and fall, allowing for a wide range of height adjustment. The upper plate 10 can slide inside the top plate 9 via the vertical rod 11. The spring 12 works in conjunction with the rise and fall of the upper plate 10 to stretch or contract accordingly, facilitating the independent small-range adjustment of the vertical height of the curved plate. The operator rotates the fixed plate 76, which drives the lead screw 74 to rotate. The rotation of the lead screw 74 drives the sleeve 75 and the side plate 77 to move. The side plate 77 drives the sliding sleeve 79 to move. The sliding sleeve 79 slides on the fixed rod 78 and stretches the spring 710, thereby adjusting the distance between the glue roller 715 and the curved plate, facilitating subsequent glue application. The mounting plate 714 is rotatably connected to the side plate 77. An auxiliary spring is set between the mounting plate 714 and the side plate 77 to facilitate the sliding of the curved plate.

[0038] Pump body 711 draws glue from inside glue tank 72 through feed pipe 712. The glue enters connecting pipe 716. As the glue coating roller 715 rolls to apply glue, the glue coating roller 715 drives the lower push rod 727 to rotate. The lower push rod 727 intermittently squeezes trapezoidal block 726. Trapezoidal block 726 drives sealing sleeve 719 to slide. Sealing sleeve 719 drives slider 721 and sliding plate 722 to slide. Slider 721 slides inside inner groove 718, causing sliding plate 722 to separate from fixed plate 724. Glue flows from through hole 723 into feed hole 725, and then is replenished to inner plate 729 from auxiliary pipe 728, which facilitates intermittent replenishment of glue coating roller 715.

[0039] The coating roller 715 also drives the upper push rod 731 to rotate. The upper push rod 731 squeezes the bending rod 737, which drives the mounting frame 735 to rotate. The connecting plate 733 rotates around the side rod 732, and the connecting plate 733 stretches the spring 734. When the upper push rod 731 separates from the bending rod 737, the elastic force of the spring 734 drives the connecting plate 733 and the mounting frame 735 to reset, so that the spreading roller 736 will swing back and forth and spread evenly.

[0040] This invention relates to the use of piano wire springs for all springs, which have a large spring force coefficient, and rubber pads are provided at both ends of the spring to reduce the reciprocating extension and contraction of the spring.

[0041] like Figure 1 and Figure 12 - Figure 13 As shown, clamping assemblies 3 are evenly arranged on the outer side of the placement plate 2. The clamping assembly 3 includes clamping plate 1 31, clamping plate 2 33 and pressure plate 35. Two bonding plates 32 are fixedly connected to one side of the bottom of clamping plate 1 31. The bonding plates 32 and clamping plate 2 33 are fixed by bolts. Slots 34 are evenly opened inside clamping plate 1 31 and bonding plate 32.

[0042] The pressure plate 35 has a sliding groove 36 inside, and the clamping plate 31 and the bonding plate 32 are all slidably connected to the sliding groove 36. The slot 34 has a sliding block 37 and a wedge 38 inside.

[0043] Example 2: Figure 12 - Figure 13 As shown, the hoisting device installed on column 1 stacks the arc-shaped plates in the V-shaped groove on top of the placement plate 2. After applying glue, the operator uses oil pump 4 to press and fix the stacked arc-shaped plates. Then, clamp plate 31 is attached to one side of the arc-shaped plate, and clamp plate 33 is attached to the other side of the arc-shaped plate. Clamp plate 31 and clamp plate 33 are fixed with bolts. Then, pressure plate 35 is placed on the outside of clamp plate 31 and clamp plate 33, so that clamp plate 31 and clamp plate 33 are located in the sliding groove 36. Then, insert block 37 and wedge block 38 are inserted into the nearest slot 34 above pressure plate 35, so that insert block 37 presses pressure plate 35, thereby pressing and fixing the stacked arc-shaped plates, improving positioning stability and reducing pressing deviation.

[0044] Working principle: When using this device, firstly, as... Figure 1 - Figure 13As shown, the hoisting device installed on column 1 stacks the arc-shaped plates in the V-shaped groove on top of the placement plate 2. The operator rotates the fixed plate 76, which drives the lead screw 74 to rotate, adjusting the distance between the glue application roller 715 and the arc-shaped plates to facilitate subsequent glue application. The pump body 711 draws glue from the inside of the glue tank 72 through the feed pipe 712. The glue enters the connecting pipe 716. As the glue application roller 715 rolls to apply glue, the glue application roller 715 drives the lower push rod. When 727 rotates, the lower push rod 727 intermittently presses the trapezoidal block 726. The trapezoidal block 726 drives the sealing sleeve 719 to slide, which in turn drives the slider 721 and the sliding plate 722 to slide. The slider 721 slides inside the inner groove 718, causing the sliding plate 722 to separate from the fixed plate 724. Glue flows from the through hole 723 into the material hole 725, and then is replenished into the inner plate 729 through the auxiliary tube 728, facilitating intermittent replenishment of the glue-applying roller 715 for glue application. Roller 715 also drives the upper push rod 731 to rotate. The upper push rod 731 presses against the bending rod 737, which in turn drives the mounting bracket 735 to rotate. The connecting plate 733 rotates around the side rod 732, and the connecting plate 733 stretches the spring 734. When the upper push rod 731 separates from the bending rod 737, the elastic force of the spring 734 causes the connecting plate 733 and the mounting bracket 735 to reset, causing the smoothing roller 736 to oscillate back and forth for smoothing. The operator uses oil pump 4 to press and fix the stacked arc plates. Then, clamp plate 31 is attached to one side of the arc plate and clamp plate 33 is attached to the other side of the arc plate. Clamp plate 31 and clamp plate 33 are fixed with bolts. Then, pressure plate 35 is placed on the outside of clamp plate 31 and clamp plate 33. Then, insert block 37 and wedge block 38 are inserted into the nearest slot 34 above pressure plate 35, so that insert block 37 presses pressure plate 35, thereby pressing and fixing the stacked arc plates.
