Abstract
An axial wobble adjusting and positioning device for sanding belt of wide-belt sanding machine is composed of a vertical shaft, an eccentric shaft, an adjusting handle, a frame, a disc and a control cylinder. The device is characterized in that a worm coaxial with the vertical shaft is arranged on the vertical shaft and is engaged with a worm wheel; the shaft of the worm wheel is connected with the frame through a bearing and a support; a pointer is arranged on the shaft of the worm wheel; and a dial disc is arranged at a position corresponding to the pointer. The axial wobble adjusting and positioning device has the advantages of convenient adjustment, reliable operation, short adjustment and control time and high accuracy, and can significantly improve the production efficiency without changing the original control system. The device can control the magnitude of axial wobble of the sanding belt of the wide-belt sanding machine within plus or minus 0.5 mm, improve the surface roughness of wood component from 5.19 mum to 2.21 mum, and improve the service life of sanding belt by twice or more, thereby making optimal workpiece grinding possible and greatly improving the grinding quality. The device has the advantages of simple structure, low cost, stable performance, long service life, etc., and has promotional value.
Description
Technical field
The utility model relates to the improvement of mechanism in the abrasive band axial wobble control system of wide-belt sander, is that positioner is regulated in a kind of abrasive band axial wobble of wide-belt sander specifically, belongs to the parts among the wood based panel manufacturing machinery.
Background technology
The control of the abrasive band axial wobble of wide-belt sander, directly technical indicators such as the service life in the grinding skin precision of the influence woodwork that processes, abrasive band and production efficiency.But the adjusting of the abrasive band axial wobble of wide-belt sander control at present is the control and regulation device that adopts the manual adjustment mode mostly.The structure of this control and regulation device is provided with control cylinder 6, the disk 5 that is connected with control cylinder piston rod contact, and the eccentric shaft 2 that is connected with a joggle of disk gap as shown in Figure 1 on the support 1 of wide-belt sander; Be provided with regulating handle 4 and vertical shaft 3 on eccentric shaft, the top of vertical shaft is connected with idler roller 01 contact; Driving mechanism drives idler roller and rotates, and rotates thereby drive abrasive band 02, and idler roller is bearing on the support through tensioning cylinder 03.The displacement of idler roller axial wobble, the axial wobble in abrasive band just is sent to control cylinder by vertical shaft, eccentric shaft, disk and piston rod, again by the control system control and regulation that are connected with control cylinder.(be that drawing is clear, do not draw the driving mechanism of wide-belt sander among Fig. 1, and the control system that is connected with control cylinder etc.)
Utilize regulating handle 4 manual adjustment control position of eccentric, can pass through control cylinder and control system thereof, reach the purpose of regulating the axial wobble of control idler roller, just regulate the axial wobble of having controlled the abrasive band, locking regulating handle after adjusting control is finished.
This axial wobble of regulating the control abrasive band with regulating handle, owing to there is not display unit, can only lean on people's experience to carry out, so regulating the amount of control is difficult to accomplish accurately, and need repeatedly to regulate repeatedly just can reach required state, inefficiency has influenced the crudy of woodwork and the functional reliability of wide-belt sander greatly.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, and cost is low, can accurately regulate the abrasive band axial wobble of the wide-belt sander of control abrasive band oscillating quantity and regulate positioner.
The technical scheme that realizes the utility model purpose is:
Positioner is regulated in the abrasive band axial wobble of this wide-belt sander, form by vertical shaft, eccentric shaft, regulating handle, support, disk and control cylinder, be characterized on vertical shaft, being provided with and the vertical shaft coaxial worm, the worm and wheel engagement, the worm-wheel shaft of worm gear is connected with support through bearing, support, is provided with pointer on the worm-wheel shaft of worm gear.
In order to regulate the more accurate of control, on the relative position of pointer, be provided with dial.
Regulate the pollution that positioner is not subjected to dust in the site environment etc. in order to make, it is more reliable to work, and is provided with outer cover and transparent window in the periphery of pointer and dial.
The utility model is simple in structure, can adopt general parts and processing method to make, and can be installed in easily in the abrasive band axial wobble control and regulation device of original wide-belt sander, implements easily.
Compare with original control and regulation device, have following advantage:
1, shortened the adjusting control time of wide-belt sander abrasive band axial wobble, regulated very conveniently, regulated quantity is accurate, and reliable operation significantly improves production efficiency;
2, regulate the control accuracy height, under the situation that does not change original control system, the amount of wide-belt sander abrasive band axial wobble is controlled at ± 0.5mm in;
3, improved the technical performance of wide-belt sander, can make the surface roughness on woodwork surface bring up to 2.21 μ m, improved the service life in abrasive band more than 2 times by 5.19 μ m;
4, whole apparatus structure is simple, and cost is low, stable performance, reliable operation, long service life.
Positioner is regulated in the abrasive band axial wobble of wide-belt sander of the present utility model, can regulate the axial wobble amount in control abrasive band efficiently, for the optimal process grinding work piece provides possibility, has greatly improved grinding quality, has promotional value.
