Abstract
The utility model relates to a tension supporting device of a tension roll of a wide belt sander. The tension roll is installed on a supporting beam connected with a stander via the tension supporting device. The tension supporting device comprises a central tension supporting mechanism and lateral tension supporting mechanisms. The central tension supporting mechanism is positioned at the middle part of the supporting beam. The lateral tension supporting mechanisms are installed at both sides of the central tension supporting mechanism and are symmetrically distributed. The central tension supporting mechanism adopts a hinged air cylinder or hinged shaft. The lateral tension supporting mechanisms at the both sides adopt flexible air cylinders or air chambers or mechanical springs. The central tension supporting mechanism and one pair or more than one pair of added lateral tension supporting mechanisms are tensioned synchronously. The force-bearing points of the supporting beam are added so as to fully solve the deformation problem of the supporting beam and efficiently improve the work precision and the service life of the sander.

Technical field
The utility model relates to a kind of wide-belt sander, relates in particular to the tensioning supporting arrangement of wide-belt sander idler roller, belongs to the sander technical field.
Background technology
Wide-belt sander mainly is made up of frame, motor, transmission device, sand roller, idler roller, abrasive band, feed mechanism etc.The sand roller is installed on the frame through bearing block; Idler roller is installed on the backbar through bearing block, and backbar is connected with frame through the tensioning supporting arrangement, and idler roller can parallelly along the vertical direction move by the tensioning supporting arrangement; Between sand roller and idler roller, be with the abrasive band, by moving of idler roller, can change and the sand roller between distance, thereby realize the loading and unloading and the tensioning in abrasive band.Other is provided with the tensioning pressure adjusting device, to regulate the abrasive band tensile force.Feed mechanism is sent workpiece to, and motor drives the abrasive band rotation, with the sand turning work piece through actuator drives sand roller or idler roller.
Prior art, the tensioning supporting arrangement of wide-belt sander idler roller is: the one, only by cylinder support and tensioning in the middle of the backbar; The 2nd, be the jointed shaft supporting in the middle of the backbar, only a pair of air bag tensioning is adopted at two ends.Its weak point is: during idler roller tensioning abrasive band, idler roller backbar force part only is a bit middle or two ends 2 points, and stress point is few, and backbar easily produces distortion, thereby influence the stationarity of idler roller running, finally reduce the operating accuracy and the service life of sander.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of tensioning supporting arrangement of wide-belt sander idler roller is provided, the problem on deformation that is intended to effectively solve the idler roller backbar, the operating accuracy and the service life of raising sander.
The purpose of this utility model is achieved through the following technical solutions:
The tensioning supporting arrangement of wide-belt sander idler roller, idler roller is installed on the backbar, the sand roller is installed on the frame, backbar adopts the tensioning supporting arrangement to be connected with frame, it is characterized in that: described tensioning supporting arrangement comprises center tensioning supporting device and side tensioning supporting device, described center tensioning supporting device is positioned at the middle part of backbar, and described side tensioning supporting device is arranged on the both sides of center tensioning supporting device and is symmetrical distribution.
Further, the tensioning supporting arrangement of above-mentioned wide-belt sander idler roller is provided with a pair or more of side tensioning supporting device in the bilateral symmetry of described center tensioning supporting device, and wherein an offside tensioning supporting device is distributed in the two ends of backbar.
Further, the tensioning supporting arrangement of above-mentioned wide-belt sander idler roller, described center tensioning supporting device adopts hinged cylinder or hinging supporting shaft.
Further, the tensioning supporting arrangement of above-mentioned wide-belt sander idler roller, described side tensioning supporting device adopts flexible cylinder or air bag or mechanical spring.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
Only adopt on the technical foundation of a pair of air bag tensioning at the idler roller backbar by middle cylinders tensioning or two ends, increase in center tensioning supporting device bilateral symmetry position a pair of or a pair of with the upside strainer, center tensioning supporting device and increase a pair of or a pair of with the tensioning simultaneously of upside tensioning supporting device.The backbar stress point increases to 3 or more, and along with stress point increases, the distortion that backbar produces correspondingly significantly reduces, and has fully solved the backbar problem on deformation, has effectively improved the operating accuracy and the service life of sander, has fabulous using value.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: structural representation of the present utility model.
The implication of each Reference numeral among the figure: 1-sand roller, 2-idler roller, 3-abrasive band, 4-frame, 5-center tensioning supporting device, 6-side tensioning supporting device, 7-backbar.
The specific embodiment
Wide-belt sander, mainly comprise sand roller 1, idler roller 2, abrasive band 3, frame 4, driving belt wheel apparatus and motor, sand roller 1 is a drive roll, idler roller 2 is a driven roll, between sand roller 1 and idler roller 2, be equipped with abrasive band 3, for guaranteeing the tensile force in abrasive band 3, between sand roller 1 and idler roller 2, be provided with tunable arrangement, to regulate the distance between two rollers easily.
The tensioning supporting arrangement of wide-belt sander idler roller as shown in Figure 1, sand roller 1 is installed on the frame 4 through bearing block, idler roller 2 is installed on the backbar 7 through bearing block, and the middle part of backbar is connected with center tensioning supporting device 5, and tensioning supporting device 5 in center is connected with frame 4.Be with abrasive band 3 between sand roller 1 and the idler roller 2.Also be arranged with a pair of in the both sides of center tensioning supporting device 5 or number offside tensioning supporting device 6, decide according to the working width of wide-belt sander.Be typically provided with two offside tensioning supporting devices, wherein an offside tensioning supporting device is distributed in the two ends of backbar.During specific design, center tensioning supporting device 5 adopts hinged cylinder or hinging supporting shaft, and the side tensioning supporting device 6 of tensioning supporting device both sides, center adopts flexible cylinder or air bag or mechanical spring.If center tensioning supporting device 5 adopts hinging supporting shaft, then have four supporting stress points on the backbar; If center tensioning supporting device 5 adopts hinged cylinder, then have five supporting stress points on the backbar.
The utility model the idler roller backbar only by the middle cylinders tensioning or only two ends adopt on the basis of a pair of air bag tensioning, hinged cylinder or hinging supporting shaft bilateral symmetry position increase a pair of or a pair of above flexible cylinder in the centre, when idler roller tensioning abrasive band, the backbar stress point increases to 3 or more.The backbar stress point increases, and then the distortion of Chan Shenging correspondingly significantly reduces.
Technical solutions of the utility model efficiently solve idler roller backbar problem on deformation, have significantly improved the operating accuracy and the service life of sander.For working width is 6 feet to 8 feet wide-belt sander, and effect of the present utility model is especially obvious, is worthy to be popularized.
