For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0024] Please refer to Figures 1 to 5 The utility model provides a kind of 4-row pressing wheel device for narrow plate edge sealing, including first pressing plate 1 and second pressing plate 2 being arranged mutually parallel, the outside of first pressing plate 1 is equipped with several first outer pressing wheel 3, and the inside is equipped with several first inner pressing wheel 4;The outside of second pressing plate 2 is equipped with several second outer pressing wheel 5, and the inside is equipped with several second inner pressing wheel 6;The first inner pressing wheel 4 and the second inner pressing wheel 6 are alternately arranged.
[0025] In the existing edge banding machine, a single row of pressure wheels is usually adopted, and a row of pressure wheels is arranged to press the surface of the plate to stabilize the conveying of the plate and perform gluing and edge banding during the conveying process. However, in order to adapt to most plates, the single row of pressure wheels is usually arranged at the center position of the conveying path, so that it is difficult to process narrow plates with small edge width, because the small-size narrow plate is difficult to be stably conveyed after being pressed against the edge, and the top surface of the small-size narrow plate is small or difficult to touch the single row of pressure wheels, so that the small-size narrow plate can only be manually pressed and fed for edge banding.
[0026] In the embodiment of the utility model, 4 rows of pressure wheels are adopted, and correspondingly, the equipment conveying the plate below the 4 rows of pressure wheels can use a caterpillar conveyor or a belt conveyor to convey the plate. In the embodiment, a plurality of first outer pressure wheels 3 and first inner pressure wheels 4 are arranged on both sides of the first pressing plate 1, and a plurality of second outer pressure wheels 5 and second inner pressure wheels 6 are arranged on both sides of the second pressing plate 2; the plurality of first outer pressure wheels 3, first inner pressure wheels 4, second outer pressure wheels 5 and second inner pressure wheels 6 along the length direction respectively form 4 rows of pressure wheel structures, and the following will be described by taking the position of the second pressing plate 2 as the inner side of the edge banding machine as an example: when the narrow plate is pressed against the inner side, the edge banding equipment works on the narrow plate on the outer side of the edge banding machine. At this time, the narrow plate can be conveyed in the 4 rows of pressure wheel structures. When the width of the narrow plate is small, the narrow plate can be conveyed under the simultaneous pressing of the second outer pressure wheels 5 and the second inner pressure wheels 6; when the width of the narrow plate increases, the narrow plate can be conveyed under the common pressing of the second outer pressure wheels 5, the second inner pressure wheels 6 and the first inner pressure wheels 4; when the width of the narrow plate continues to increase, the narrow plate can be conveyed under the common pressing of the second outer pressure wheels 5, the second inner pressure wheels 6, the first inner pressure wheels 4 and the first outer pressure wheels 3. The 4 rows of pressure wheels work cooperatively to stably press the edge of the narrow plate. In the continuous edge banding process, the efficient pressing process can speed up the conveying speed of the plate and reduce the time required for edge banding, thereby improving the overall edge banding efficiency and meeting the efficiency requirements of large-scale production.
[0027] The embodiment adopts a plurality of first outer pressure wheels 3, first inner pressure wheels 4, second outer pressure wheels 5 and second inner pressure wheels 6 to respectively form 4 rows of pressure wheel structures, and the multi-pressure wheel design disperses the pressure, so that the load borne by each pressure wheel is relatively reduced, and the possibility of damage of a single pressure wheel due to excessive stress is reduced. Moreover, even if a certain pressure wheel fails, other pressure wheels can still maintain the pressing action on the narrow plate to a certain extent, so that the entire edge banding work is not immediately interrupted, the downtime of the equipment caused by the pressure wheel failure is reduced, and the stability and reliability of the equipment operation are improved.
[0028] Further, the structure of the utility model discloses, through adjusting the distance between the first pressing plate 1 and the second pressing plate 2, and the size, quantity and mounting position of each pressing wheel, different width and thickness narrow plate can be flexibly adapted, and the versatility and practicality of the device are improved.
[0029] Preferably, the first outer pressing wheel 3 outside the first pressing plate 1 and the second outer pressing wheel 5 outside the second pressing plate 2 are symmetrically arranged. Two rows of symmetrically arranged outer pressing wheels make the plate receive uniform lateral force during the edge sealing process, avoid the plate from being offset and deformed due to excessive pressure on one side, ensure that the plate keeps linear motion during the edge sealing process, thereby improving the linearity and precision of edge sealing, and make the edge sealing strip be uniformly and smoothly pasted on the edge of the narrow plate.
[0030] Preferably, the axis of the first inner pressing wheel 4 coincides with the center line between the axis of the two closest first outer pressing wheels 3 to the first inner pressing wheel 4, and the axis of the second inner pressing wheel 6 coincides with the center line between the axis of the two closest second outer pressing wheels 5 to the second inner pressing wheel 6. Through the above structure, when the first inner pressing wheel 4 and the second inner pressing wheel 6 are alternately arranged, the distance between them can be kept fixed, the axis of the inner pressing wheel coincides with the center line between the axis of the two closest outer pressing wheels, and the pressure can be more uniformly transmitted from the outer pressing wheel to the inner pressing wheel through the plate, or from the inner pressing wheel to the outer pressing wheel through the plate.
[0031] Preferably, the distance between the axis of the two adjacent first outer pressing wheels 3, the distance between the axis of the two adjacent second outer pressing wheels 5 and the distance between the axis of the first inner pressing wheel 4 and the second outer pressing wheel 5 are equal. In the embodiment, the equal axis distance makes the pressing wheels form uniform pressure point distribution on the plate, so that the plate conveying is more stable, and the plate shaking condition is avoided.
[0032] Preferably, the structure of the first pressing plate 1 is the same as that of the second pressing plate 2, the first pressing plate 1 is composed of a plurality of cross plates 11, the cross section of the cross plate 11 is in a convex structure, the two ends of the cross plate 11 are respectively provided with connecting ends 111, and the connecting ends 111 are provided with mounting holes 112. In the embodiment, the first pressing plate 1 and the second pressing plate 2 have the same structure, and unified molds and process flows can be used for manufacturing in the production process, so that the production complexity and cost are reduced. At the same time, the standardized pressing plate is convenient for interchanging in the installation process, the installation and debugging time is reduced, and the equipment assembly efficiency is improved. The first pressing plate 1 is composed of a plurality of cross plates 11, each cross plate 11 is provided with connecting ends 111 and mounting holes 112 at both ends, and the cross plates 11 can be quickly spliced through bolts and other connecting members, without complex welding or other processing technology, so that the assembly difficulty is greatly reduced, and the equipment installation period is shortened.
[0033] Preferably, the first outer pressing wheel 3, the first inner pressing wheel 4, the second outer pressing wheel 5 and the second inner pressing wheel 6 are all deep groove ball bearings. In the present embodiment, the friction coefficient between the rolling elements and the raceway of the deep groove ball bearings is small, and the deep groove ball bearings can rotate with low resistance, which makes the plate material move quickly and smoothly under the action of the pressing wheels, and the stability of the moving process is good, and the friction damage to the surface of the plate material is reduced.
[0034] Preferably, a connecting plate is arranged between the first pressing plate 1 and the second pressing plate 2, one side of the connecting plate is connected with the inner side of the first pressing plate 1, and the other side is connected with the inner side of the second pressing plate 2. Through the above structure, the connecting plate connects the first pressing plate 1 and the second pressing plate 2 together, so that they form a stable overall structure, which ensures that the two pressing plates can work cooperatively and maintain the stability of the relative position when performing edge sealing and other operations on the plate material, thereby ensuring that the pressure applied to the plate material is uniform and consistent.
[0035] Preferably, the lower end surface of the first outer pressing wheel 3, the lower end surface of the first inner pressing wheel 4, the lower end surface of the second outer pressing wheel 5 and the lower end surface of the second inner pressing wheel 6 are located on the same plane. When the lower end surfaces of these pressing wheels are on the same plane, the entire edge region of the plate material can be ensured to receive uniform pressure from each pressing wheel when the plate material is pressed.
[0036] Preferably, an adjusting mechanism is arranged between the first pressing plate 1 and the second pressing plate 2, and the adjusting mechanism is used to adjust the distance between the first pressing plate 1 and the second pressing plate 2. By arranging the adjusting mechanism, the distance between the first pressing plate 1 and the second pressing plate 2 can be adjusted conveniently, so that the equipment can be suitable for edge sealing operation of plate materials with different thicknesses. Whether it is a thinner plate material or a thicker plate material, the distance between the first pressing plate 1 and the second pressing plate 2 can be adjusted to ensure that each pressing wheel applies appropriate pressure to the plate material, so that the plate material can be stably conveyed.
[0037] Preferably, the adjusting mechanism comprises a screw rod assembly and a plurality of mutually parallel sliding rails, the sliding rails are arranged perpendicularly to the first pressing plate 1 and the second pressing plate 2, the sliding rails are provided with a first sliding block and a second sliding block, the first sliding block is connected with the first pressing plate 1, and the second sliding block is connected with the second pressing plate 2; the screw rod assembly comprises a bidirectional screw rod, the bidirectional screw rod is provided with a first nut seat and a second nut seat, the first nut seat is connected with the first pressing plate 1, and the second nut seat is connected with the second pressing plate 2; one end of the bidirectional screw rod is provided with an adjusting hand wheel, and the adjusting hand wheel is used for driving the bidirectional screw rod to rotate. Through the above structural arrangement, the bidirectional screw rod has two sections of threads with opposite rotation directions, when the adjusting hand wheel drives the bidirectional screw rod to rotate, the first nut seat and the second nut seat move in opposite directions along the screw rod. This design enables the first pressing plate 1 and the second pressing plate 2 to be synchronously and accurately close to or away from each other, so that the distance between the two can be accurately adjusted. For example, when processing plates of different thicknesses, the distance between the first pressing plate 1 and the second pressing plate 2 can be adjusted to an appropriate range according to the actual thickness of the plate by rotating the adjusting hand wheel, so that each pressing wheel can cover the surface of the plate, thereby ensuring the stable conveying of the plate.
