Description

Technical Field

[0001] This utility model belongs to the field of door panel edge banding technology, specifically relating to a door panel edge banding rolling structure. Background Technology

[0002] The door panel edge banding roll forming structure is a device used to firmly adhere the edge banding material to the edge of the door panel. It is commonly used in furniture manufacturing, automobile manufacturing and other fields. In the door panel edge banding process, the traditional roll forming structure has many shortcomings: on the one hand, its pressure is mostly fixed, which is difficult to adapt to the slight tolerance of the door panel thickness or the edge banding strips of different soft and hard materials. Insufficient pressure can easily lead to air bubbles and curling of the edge banding strip, or excessive pressure can cause cracking of the door panel substrate and deformation of the edge banding strip. On the other hand, the roll forming roller can only roll the side of the door panel, and cannot roll the corners or curved surfaces of the door panel. It is easy to have missed pressure or uneven local pressure, which affects the sealing and aesthetics of the edge banding. Therefore, we propose a door panel edge banding roll forming structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a door panel edge sealing rolling structure, including a base plate 1, a fixed platform 2 fixed to the top of the base plate 1, roller plates 3 evenly spaced at the top of the base plate 1, and electrically driven telescopic mechanisms 4 connected to the fixed platform 2 evenly spaced at the top of the base plate 1. A telescopic rod 5 is provided at the end of the electrically driven telescopic mechanism 4 relative to the interior of the fixed platform 2. An adaptive tensioning component is provided between the roller plates 3 and the electrically driven telescopic mechanism 4. The adaptive tensioning component includes sliding grooves 100 evenly spaced through the top of the fixed platform 2. A fixed seat 101 is fixed at the end of the telescopic rod 5 relative to the interior of the fixed platform 2. The interior of the fixed seat 101... An L-shaped connecting rod 102 is provided, which passes through the inside of the slide groove 100 and connects to the roller plate 3. A telescopic spring 103 connected to the L-shaped connecting rod 102 is provided inside the fixed seat 101. Through the adaptive tensioning assembly composed of the slide groove 100, fixed seat 101, L-shaped connecting rod 102 and telescopic spring 103, the tension during the rolling process can be dynamically compensated by the elastic potential energy of the telescopic spring 103 based on the adjustment of the electric drive telescopic machine 4. This ensures that the rolling roller and the edge of the door panel always maintain uniform contact pressure, avoids overpressure (substrate cracking) or underpressure (weak edge sealing) caused by fluctuations in door panel thickness or conveying deviation, and improves edge sealing stability.

[0020] In this embodiment, preferably, a swivel groove 200 is provided at the bottom end of the roller plate 3, and a swivel block 201 is fixed at the top end of the L-shaped connecting rod 102. The swivel block 201 is rotatably connected to the swivel groove 200. Universal ball grooves are symmetrically provided on the side of the swivel block 201. Universal balls 202 are provided inside the universal ball grooves. The universal balls 202 are in contact with the inner wall of the swivel groove 200. The swivel groove 200 at the bottom end of the roller plate 3 is rotatably connected to the swivel block 201 at the top end of the L-shaped connecting rod 102. With the rolling assistance of the universal balls 202, the roller plate 3 can adaptively rotate with the edge angle of the door panel (such as corners and curved surfaces), reducing jamming or frictional resistance during rolling, ensuring the fitting accuracy at complex edges, and reducing wear of parts.

[0021] In this embodiment, preferably, the top of the roller plate 3 is provided with an adjustable-spacing side rolling assembly. The adjustable-spacing side rolling assembly includes a rolling main roller 300 fixed to the top of the roller plate 3, and a side pressure roller 301 is sleeved on the top of the rolling main roller 300. The combination design of the rolling main roller 300 and the side pressure roller 301 forms an all-round rolling of the edge and side of the door panel. The rolling main roller 300 is responsible for the main pressure output, and the side pressure roller 301 assists in smoothing the edge banding strip, jointly eliminating air and avoiding air bubbles, and improving the flatness and firmness of the edge banding.

[0022] In this embodiment, preferably, the top of the rolling main roller 300 is provided with a docking groove 400, and the inside of the side roller 301 is fixed with a docking rod 401 embedded in the docking groove 400. The surface of the docking rod 401 is provided with a guide groove 402, and the inside of the docking groove 400 is fixed with a guide block 403 that passes through the guide groove 402. The guide block 403 is slidably connected to the docking groove 400. The docking groove 400 of the rolling main roller 300 cooperates with the docking rod 401 of the side roller 301. Combined with the sliding guidance of the guide block 403 and the guide groove 402, the height adjustment of the side roller 301 is more precise and stable, avoiding deviation during the adjustment process, ensuring the consistency of the spacing adjustment, and making it more reliable when adapting to door panels of different thicknesses.

[0023] In this embodiment, preferably, locking holes 500 are symmetrically provided through the surface of the side pressure roller 301, and locking rods 501 are provided on the surface of the side pressure roller 301 and screwed into the locking holes 500. The end of the locking rod 501 is pressed and fitted to the surface of the rolling main roller 300. The locking rod 501 is pressed and fitted to the rolling main roller 300 through the locking holes 500, which can firmly lock the adjustment position of the side pressure roller 301, prevent the spacing from changing due to vibration during the rolling process, ensure the structural stability during long-term use, and reduce the rework rate.

[0024] In this embodiment, preferably, a linkage plate 600 is provided at the top of the side pressure roller 301. The top of the linkage plate 600 has through holes 601 at equal intervals. A rotating shaft 602 is fixed at the top of the side pressure roller 301, passing through the inside of the through hole 601. The rotating shaft 602 is rotatably connected to the through hole 601. The linkage plate 600 connects multiple side pressure rollers 301 through the rotating shaft 602 to achieve synchronous adjustment, greatly improve the efficiency of spacing adjustment, and reduce the tediousness of operating one by one. The rotatable connection between the rotating shaft 602 and the through hole 601 ensures that each pressure roller independently adapts to the movement of the door panel during rolling, without interfering with the rolling accuracy.

[0025] In this embodiment, preferably, the side pressure roller 301 has a circular cross-section, and the cross-section of the side pressure roller 301 is equal to the cross-section of the roller plate 3. Rubber pads are fixed to the bottom end of the side pressure roller 301 and the top end of the roller plate 3. The rubber pads on the top end of the side pressure roller 301 and the roller plate 3 can buffer the rigid contact during rolling, avoid scratching the surface of the edge banding strip (especially soft materials such as PVC), and at the same time enhance the friction with the door panel, improve the tightness of the fit, and protect the appearance quality of the door panel and the edge banding strip.

[0026] The working principle and usage process of this utility model are as follows: When it is necessary to perform edge sealing and rolling on a door panel, the distance between the side pressure roller 301 and the roller plate 3 can be adjusted according to the thickness of the door panel, so that the door panel can be accurately embedded in the distance between the side pressure roller 301 and the roller plate 3 and closely connected with the rolling main roller 300. First, loosen the locking rod 501 on the surface of each side pressure roller 301, so that its end separates from the surface of the rolling main roller 300 and is screwed into the locking hole 500. This releases the positioning of the side pressure roller 301. Then, the linkage plate 600 lifts the side pressure roller 301 upwards, causing it to be on the surface of the rolling main roller 300. Sliding the rollers upwards will move all the side pressure rollers 301 upwards at once, and will also move the docking rod 401 inside the docking groove 400. Simultaneously, it will cause the guide groove 402 to slide on the surface of the guide block 403, providing a guiding function. This allows adjustment of the distance between the side pressure rollers 301 and the roller plate 3. Once the distance between the side pressure rollers 301 and the roller plate 3 is adjusted to the appropriate position, stop pulling the linkage plate 600. Then, tighten the pair of locking rods 501 on the surface of each side pressure roller 301 one by one, so that the ends of the locking rods 501 unscrew from the locking holes 500 and press against the surface of the main roller 300. Once the side pressure roller 301 is locked in place, the electric telescopic machine 4 extends the telescopic rod 5 to adjust the position of the roller plate 3 according to the usage requirements. After the roller plate 3 is adjusted to the appropriate position, it can be driven by the door panel on the edge banding machine. Then, the edge banding strip coated with glue adheres to the side of the door panel and enters the side pressure roller 301 and the inner side of the roller plate 3 together with the surface of the rolling main roller 300 for rolling. At the same time, the telescopic spring 103 pushes the L-shaped connecting rod 102 inside the fixed seat 101 to drive the roller plate 3 to dynamically compensate for the tension, ensuring that the rolling main roller 300 and the side of the door panel are in contact. Maintaining appropriate contact pressure, the roller plate 3, the main rolling roller 300, and the side pressure roller 301 rotate synchronously. The main rolling roller 300 rolls the edge banding strip on the side of the door panel, and the side pressure roller 301 rolls the edge banding strip on the roller plate 3 and the door panel edge together with the roller plate 3 and the edge banding strip on the door panel edge. This makes it fit tightly against the door panel edge. At the same time, the rolling process can also smooth the edge banding strip and remove air, making the edge banding effect more firm and flat.
