Description

Technical Field

[0001] This utility model relates to the field of stone plastic flooring production, and in particular to an adhesive applicator for stone plastic flooring production. Background Technology

[0002] A glue application device for SPC flooring production is a specialized piece of equipment used to achieve uniform glue application and interlayer bonding during the manufacturing process of SPC flooring. Its core functions include glue spraying, coating uniformity control, height adjustment, and excess glue recovery. This type of device typically consists of a glue application tank, spray nozzles, lifting and adjusting components, and rotating rollers. For example, it uses three sets of nozzles to spray the SPC flooring during transport, and then uses rotating rollers to spread the glue evenly.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN220514571U, a coating structure for stone plastic flooring is disclosed, which uses a spring to adjust the coating roller. However, in practical applications, it has been found that using only a spring for pressure application results in the pressure only compressing the spring when encountering a protrusion. The pressure of the coating roller on the protruding position increases, causing the glue to be squeezed out due to excessive force at the squeezed position. This results in uneven glue concentration on both sides, affecting the subsequent bonding effect. Utility Model Content

[0004] The purpose of this invention is to provide an adhesive applicator for the production of stone-plastic flooring in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A gluing device for producing stone plastic flooring includes a conveying mechanism for lifting and conveying and a gluing mechanism for spraying glue. The gluing mechanism is installed on the upper side of the conveying mechanism. It also includes a brushing mechanism for evenly applying glue, an adaptive mechanism for adjusting the brushing mechanism to adapt to the board material during gluing, and an adjusting mechanism for adjusting the hardness of the adaptive mechanism. The brushing mechanism is installed at the rear station of the gluing mechanism. The adaptive mechanism is connected to both ends of a protective cover on the brushing mechanism. The adjusting mechanism is connected to the pressure adjustment part of the adaptive mechanism.

[0007] The glue application mechanism includes a protective cover, and a glue application roller is installed inside the protective cover. The main shaft at one end of the glue application roller is connected to a glue application motor through a transmission component.

[0008] The adaptive mechanism includes an active pressure frame, which is bolted to the protective cover. One end of the active pressure frame is connected to the main shaft via a bearing seat, and the other end is connected to the middle section of the active adjusting cylinder via a stabilizer. The center of the active pressure frame is connected to the output end of the active piston rod via a pin. The active piston rod is mounted on the active adjusting cylinder. Buffer adjusting cylinders are provided on both sides of the active adjusting cylinder. One end of the piston rod of the buffer adjusting cylinder is connected to a swing frame. The bottom of the swing frame is connected to an auxiliary pressure frame via a pin. The bottom of the auxiliary pressure frame is connected to the position where the active pressure frame connects to the active piston rod via a pin.

[0009] Preferably, the adjusting mechanism includes a pressure cylinder, which is fixed to the upper end of the protective cover. The two ends of the oil chamber at the bottom of the pressure cylinder are connected to the buffer adjusting cylinder through pressure pipes. An elastic pressure component is provided inside the pressure cylinder. A screw is connected to the upper end of the elastic pressure component. A locking block is connected to the upper end of the screw. A handwheel is connected to the input shaft of the locking block.

[0010] With this configuration, rotating the handwheel adjusts the pressure of the elastic pressure component on the buffer adjustment cylinder, thereby adjusting the elastic adjustment capability of the buffer adjustment cylinder.

[0011] Preferably, the elastic pressure assembly includes a pressure regulating plate, a pressure applying plate, and a spring. The pressure regulating plate is threadedly connected to the screw, and the pressure applying plate is slidably connected to the outside of the pressure regulating plate. Both the pressure regulating plate and the pressure applying plate are concave cylinders and nested within each other. The spring is located at the lower part corresponding to the oil cavity of the pressure cylinder, and a spring is provided between the pressure regulating plate and the pressure applying plate.

[0012] Preferably, the two ends of the spring are fixedly connected to the pressure regulating plate and the pressure applying plate by snap fasteners, and the bounce range between the pressure regulating plate and the pressure applying plate is 0mm-10mm.

[0013] Preferably, the oscillation amplitude of the adhesive roller on one side is 0mm-10mm under the pressure adjustment of the buffer regulating cylinder.

[0014] This design utilizes the range of unilateral movement to adapt to the different protrusions on both sides of the floor, thereby ensuring the uniformity of the adhesive application.

[0015] Preferably, the active pressure frame, the swing frame, and the auxiliary pressure frame are all made of aluminum alloy, and the auxiliary pressure frame has an X-shaped structure.

[0016] This design utilizes aluminum alloy to reduce gravity and minimize influencing factors.

[0017] Preferably, the conveying mechanism includes a conveying roller, which is keyed to the power rod, and the conveying roller is a rubber roller.

[0018] This setup utilizes the frictional transmission effect between the conveyor rollers and the floor surface.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The adaptive mechanism provides an elastic range for the adjustment mechanism, and the damping of the buffer adjustment cylinder and the active adjustment cylinder are used simultaneously. When applying adhesive to the floor, if the floor has curvature or protrusions, the spindle can be lifted partly under the action of the adaptive mechanism. This avoids excessive pressure on the protruding part while the other side remains unchanged, which would cause the adhesive to overflow under pressure and result in uneven adhesive concentration on both sides. This avoids the reciprocating bounce caused by the lack of damping in conventional spring structures. Furthermore, the height of the pressure adjustment plate can be adjusted according to the adhesive concentration, thereby adjusting the bounce range and pressure, avoiding the limitations of using a single damping method.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-6As shown, a gluing device for producing stone plastic flooring includes a conveying mechanism 1 for lifting and conveying and a gluing mechanism 3 for spraying glue. The gluing mechanism 3 is installed on the upper side of the conveying mechanism 1. It also includes a brushing mechanism 2 for evenly brushing glue, an adaptive mechanism 5 for adjusting the brushing mechanism 2 to adapt to the board during gluing, and an adjusting mechanism 4 for adjusting the softness and hardness of the adaptive mechanism 5. The brushing mechanism 2 is installed on the rear station of the gluing mechanism 3. The adaptive mechanism 5 is connected to both ends of the protective cover 21 on the brushing mechanism 2. The adjusting mechanism 4 is connected to the pressure adjusting part of the adaptive mechanism 5.

[0034] The glue application mechanism 2 includes a protective cover 21, a glue application roller 23 is installed inside the protective cover 21, and the main shaft 24 at one end of the glue application roller 23 is connected to the glue application motor 22 through a transmission component.

[0035] The adaptive mechanism 5 includes an active pressure frame 53, which is fixedly connected to the protective cover 21 by bolts. One end of the active pressure frame 53 is connected to the main shaft 24 through a bearing seat, and the other end of the active pressure frame 53 is connected to the middle section of the active adjusting cylinder 51 through a stabilizer 531. The center position of the active pressure frame 53 is connected to the output end of the active piston rod 52 through a pin. The active piston rod 52 is mounted on the active adjusting cylinder 51. Buffer adjusting cylinders 54 are provided on both sides of the active adjusting cylinder 51. One end of the piston rod of the buffer adjusting cylinder 54 is connected to a swing frame 55. The bottom of the swing frame 55 is connected to an auxiliary pressure frame 56 through a pin. The bottom of the auxiliary pressure frame 56 is connected to the position where the active pressure frame 53 is connected to the active piston rod 52 through a pin.

[0036] In this embodiment, the adjustment mechanism 4 includes a pressure cylinder 43, which is fixed to the upper end of the protective cover 21. The two ends of the oil chamber at the bottom of the pressure cylinder 43 are connected to the buffer adjustment cylinder 54 through the pressure pipe 46. An elastic pressure component is provided inside the pressure cylinder 43. A screw 44 is connected to the upper end of the elastic pressure component. A locking block 42 is connected to the upper end of the screw 44. A handwheel 41 is connected to the input shaft of the locking block 42. By rotating the handwheel 41, the pressure of the elastic pressure component on the buffer adjustment cylinder 54 is adjusted, thereby adjusting the elastic adjustment capability of the buffer adjustment cylinder 54.

[0037] In this embodiment, the elastic pressure assembly includes a pressure regulating plate 451, a pressure applying plate 452, and a spring 453. The pressure regulating plate 451 is connected to the screw 44 by a thread, and the pressure applying plate 452 is slidably connected to the outside of the pressure regulating plate 451. Both the pressure regulating plate 451 and the pressure applying plate 452 are concave cylinders and nested with each other. The spring 453 is located in the lower part corresponding to the oil cavity of the pressure cylinder 43, and the spring 453 is provided between the pressure regulating plate 451 and the pressure applying plate 452.

[0038] In this embodiment, the two ends of the spring 453 are fixedly connected to the pressure regulating plate 451 and the pressure applying plate 452 by snap fasteners, and the bounce range between the pressure regulating plate 451 and the pressure applying plate 452 is 0mm-10mm.

[0039] In this embodiment, the oscillation amplitude of the glue roller 23 on one side is 0mm-10mm under the pressure adjustment of the buffer adjustment cylinder 54. By utilizing the range of unilateral oscillation, it adapts to the different protrusions on both sides of the floor, thereby ensuring the uniformity of glue application.

[0040] In this embodiment, the active pressure frame 53, the swing frame 55, and the auxiliary pressure frame 56 are all made of aluminum alloy. The auxiliary pressure frame 56 has an X-shaped structure, which uses aluminum alloy to reduce gravity and reduce influencing factors.

[0041] In this embodiment, the conveying mechanism 1 includes a conveying roller 11, which is keyed to the power rod 12. The conveying roller 11 is a rubber roller, and the transmission effect is achieved by the friction between the conveying roller 11 and the floor.

[0042] Working principle: When applying glue, the motor 14 drives the conveyor roller 11 through the gearbox 13 and the power rod 12, so that the conveyor roller 11 transports the floor. At the same time, the pump of the glue spraying mechanism 3 starts to evenly pour the glue onto the floor.

[0043] The glue-applying motor 22 drives the main shaft 24 and the glue-applying motor 22 to rotate through the sprocket set (not shown), which squeezes and grinds the glue on the floor surface evenly. During the rolling and squeezing, if there is a curved bulge on one side of the floor, the bulge will impact the glue-applying roller 23. After being impacted, the glue-applying roller 23 transmits the impact upward through the main shafts 24 on both sides and the active pressure frame 53. At this time, the auxiliary pressure frame 56 and the swing frame 55 transmit the pressure to the buffer adjustment cylinder 54 through their own rocker structure.

[0044] The oil pressure in the buffer regulating cylinder 54 is transmitted through the pressure pipe 46 to the oil chamber located below the pressure plate 452 inside the pressure cylinder 43. The pressure impacts the spring 453 inside the pressure plate 452 and the pressure regulating plate 451. Through the elasticity of the spring 453 and the damping of the oil pressure, the glue roller 23 will slowly rise, and the pressure change can be relatively slow. This ensures that the glue roller 23 rises adaptively while maintaining the pressure of the glue roller 23 on the floor. This avoids the reciprocating bounce caused by the lack of damping in conventional spring structures. Furthermore, the height of the pressure regulating plate 451 can be adjusted according to the concentration of the glue, thereby adjusting the bounce range and pressure, avoiding the limitations of using a single damping form.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
