Description

Technical Field

[0001] This utility model relates to the field of adhesive coating device technology, specifically a device for uniformly coating transparent PVC edge banding strips. Background Technology

[0002] PVC edge banding is an edge banding material made primarily of polyvinyl chloride (PVC) through processes such as mixing, calendering, and vacuum forming. Its main components include PVC and appropriate additives. It is manufactured through processes such as extrusion, calendering, printing, and sealing. PVC edge banding is widely used in furniture, office furniture, kitchenware, teaching equipment, and laboratory equipment. It not only protects the cross-sections of furniture boards from environmental and usage-related damage such as moisture, but also prevents the volatilization of formaldehyde from within the boards, achieving a decorative and aesthetically pleasing effect. Furthermore, PVC edge banding is environmentally friendly, containing no harmful substances and is harmless to the human body.

[0003] As disclosed in the authorization announcement number CN221311226U, an edge banding adhesive applicator includes a base, a slot is provided at the middle of the upper end of the base, a bidirectional screw is rotatably connected to the middle of the inside of the slot, limit rods are fixedly connected to the front and rear sides of the inside of the slot, and limit components are provided on the left and right sides of the upper end of the slot.

[0004] Although it achieves the adjustment of the spacing between the limiting components through the set second servo motor, bidirectional screw and limiting rod, it can be used to limit and clamp edge banding strips of different widths. The set limiting components can clamp the two sides of the edge banding strip through multiple limiting plates. The set support plate and pressing shell can support the upper and lower sides of the edge banding strip respectively. The spacing between the pressing shell and the support plate can be adjusted by the locking screw and adjusting nut, which can be used for edge banding strips of different thicknesses.

[0005] However, this does not solve the problem that existing adhesive application devices of this type are generally not conducive to convenient air blowing for cleaning and adhesive application of transparent PVC edge banding strips. Dirt on the surface of transparent PVC edge banding strips affects the quality of adhesive application, and it is not convenient to easily tension, compact, drive, and move transparent PVC edge banding strips, thus affecting the efficiency of adhesive application of transparent PVC edge banding strips. Utility Model Content

[0006] The purpose of this utility model is to provide a device for uniformly applying adhesive to transparent PVC edge banding strips, so as to solve the problems mentioned in the background art, such as the inconvenience of convenient air blowing to clean and apply adhesive to transparent PVC edge banding strips, the presence of dirt on the surface of transparent PVC edge banding strips affecting the quality of adhesive application, and the inconvenience of convenient tensioning, compaction and driving movement of transparent PVC edge banding strips, which affect the efficiency of adhesive application to transparent PVC edge banding strips.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a transparent PVC edge banding strip uniform adhesive application device, comprising a base plate and a support frame. The support frame is installed at the top of the base plate, and a movable plate is slidably installed at the top of the base plate near the support frame. Support seats are symmetrically installed at the top of the movable plate, and a servo motor is installed on the outer wall of one set of support seats. A rotating shaft is installed at the output end of the servo motor, and the rotating shaft is movably connected to another set of support seats. The surface of the rotating shaft is fitted with the edge banding strip body. A first rotating roller is installed inside the support frame, and a second rotating roller is installed on the side of the support frame away from the first rotating roller. An air nozzle is provided inside the support frame above the first rotating roller, and a glue gun is provided inside the support frame above the second rotating roller. Stepper motors are installed on the outer walls of the support frames on the sides of the air nozzle and the glue gun, and a first threaded rod is installed at the output end of each stepper motor.

[0008] Preferably, the surface of the first threaded rod is fitted with a first threaded sleeve, and one set of first threaded sleeves is connected to the air nozzle, and another set of first threaded sleeves is connected to the glue gun.

[0009] Preferably, a limiting rod is movably installed inside the first threaded sleeve below the first threaded rod, and the limiting rod extends to the outside of the first threaded sleeve, and the limiting rod is connected to the support frame.

[0010] Preferably, a power motor is installed on the outer wall of the support frame near the glue gun, and a power shaft is installed at the output end of the power motor, with the power shaft extending to the outside of the support frame.

[0011] Preferably, a power roller is fitted onto the surface of the power shaft, and a tensioning shaft is movably installed inside a support frame on one side of the power roller.

[0012] Preferably, a tensioning roller is fitted onto the surface of the tensioning shaft, and sliders are movably mounted at both ends of the tensioning shaft.

[0013] Preferably, the support frame on one side of the slider is provided with a sliding groove, and the slider is slidably connected to the sliding groove. A connecting block is fixed inside the sliding groove, and a spring is installed at the end of the connecting block near the slider, and the spring is connected to the slider.

[0014] Preferably, slide rails are symmetrically installed on the top of the base plate below the movable plate, and limit blocks are slidably installed on the top of each slide rail, with the limit blocks connected to the movable plate. A movable motor is installed on the top of the base plate near the limit block.

[0015] Preferably, the output end of the mobile motor is equipped with a second threaded rod, and a second threaded sleeve is fitted onto the surface of the second threaded rod.

[0016] Preferably, a connecting bushing is symmetrically installed on the top end of the base plate near the second threaded sleeve, and the second threaded rod is movably connected to the connecting bushing, and the second threaded sleeve is connected to the movable plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the glue application device not only realizes the convenient air blowing cleaning and glue application of the transparent PVC edge banding strip, removing dirt from the surface of the transparent PVC edge banding strip and improving the quality of the glue application, but also facilitates the convenient tensioning and compaction of the transparent PVC edge banding strip by the glue application device.

[0018] The edge banding strip is manually placed on the surface of the rotating shaft and then manually pulled into the support frame. The edge banding strip is then pulled to the surfaces of the first and second rotating rollers. A servo motor drives the rotating shaft to rotate, releasing the edge banding strip. As the edge banding strip passes the first rotating roller, a stepper motor drives the first threaded rod to rotate, which in turn moves the first threaded sleeve. The first threaded sleeve then moves the air nozzle. A limiting rod slides inside the first threaded sleeve to provide sliding support. When the air nozzle moves above the edge banding strip, it is opened to clean the dust from the surface. When the edge banding strip passes the second rotating roller, a stepper motor drives the glue gun to a suitable position, and the glue gun is opened to apply glue to the edge banding strip. This device enables convenient air-blowing cleaning and glue application of transparent PVC edge banding strips, removing dirt from the surface and improving the quality of the glue application.

[0019] As the edge banding strip passes the power roller, the power motor drives the power shaft to rotate, which in turn drives the power roller to rotate. The power roller then moves the edge banding strip. Supported by the connecting block, the spring provides elastic support to the slider, which slides inside the groove. The slider drives the tensioning shaft and tensioning roller to move elastically, facilitating the tensioning roller and power roller to press the edge banding strip firmly. This prevents slippage when the power roller drives the edge banding strip to move, thus enabling the adhesive applicator to conveniently tension and compact the transparent PVC edge banding strip and prevent slippage during its movement.

[0020] The moving motor drives the second threaded rod to rotate, and the second threaded rod drives the second threaded sleeve to move under the movable support of the connecting bushing. The second threaded sleeve drives the moving plate to move, and the limiting block slides on the surface of the slide rail to provide sliding support for the moving plate. The moving plate drives the support base, servo motor, rotating shaft, and edge banding strip body to move, which facilitates the adjustment of the position of the edge banding strip body. This enables the glue applicator to conveniently adjust the position of the transparent PVC edge banding strip and improves the convenience of position adjustment when releasing the transparent PVC edge banding strip roll.

It is then pulled to the surfaces of the first rotating roller 28 and the second rotating roller 29. The servo motor 5 is activated, and under the movable support of the support base 4, the servo motor 5 drives the rotating shaft 6 to rotate.
