Abstract

The invention relates to woodworking equipment and relates to the improvement of the feed mechanism of woodworking machines. The purpose of the invention is to improve the processing quality of different-thickness preforms. The feeding device is seated in the form of a driving feed conveyor 5 and a belt conveyor located above the conveyor 5. A chain roller support 12, consisting of a three-section role, is pressed to the belt 10.

with the location of the end sections under the rollers, plates located between the sections. Roller support 12 is adjusted and tensioned by a spring through levers 17, and is pressed against spring-loaded rollers to the supplied blanks.

The invention relates to woodworking equipment and relates to the improvement of the feed mechanism of woodworking machines, processing lumber, draft furniture blanks, slab materials, plywood.

The aim of the invention is to increase the processing quality of different-thickness blanks.

FIG. 1 shows the device, a general view; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2

The feeding device has a drive consisting of an electric motor 1, a coupling 2, a gearbox 3, a chain transmission 4 and a driving feeding conveyor 5 with removable easily removable stops. The clamping mechanism through the housing 6 is mounted on the conveyor through the bracket 7.

The belt conveyor is a flat endless belt tensioned on the bypass 8 and tension 9 pulleys 10. The belt conveyor has a tensioning device 1. The chain roller support 12, consisting of three-section rollers I3 with the location of the end sections under the rollers, is pressed to the belt 10 14, rollers 15 and plates 16 interposed between the sections. The location of the rollers at the roller supports is on the edges, and the plates inside ensure, with a minimum width of the roller supports, the contact of the rollers across the entire width of the belt. The roller supports 12 are adjusted and tensioned by spring 17 through the levers 18 and adjusting wines.

is conveyed on the conveyor 5 to the stops and fed to the pressing device. When the workpiece enters the nip, the belt 10 is driven into motion, the rollers and the spring loaded rollers, the latter being pressed, are pressed against the two lower rollers. The device provides a more reliable clamping of small and different thickness blanks in the processing area. 2 hp ff, 3 ill.

tami. Roller support 12 is pressed against spring blanks 20 to the blanks 20, consisting of a sleeve 21 of a vertically located rod 22 with a pin 23, springs 24 of screw 25, working parts 26, rollers on an axis 27 with a washer 28 and a retaining ring. The cutting tool 29 may be a saw, cutter, etc. Press down the spring 24 of the spring-loaded rollers is adjusted by the screw 25.

The pin 23 in the groove of the sleeve 21 protects the rollers 14 from turning and ensures that the rollers, rollers and belts are in the lowest position. If necessary, the width of the conveyor, the number of clamping devices, the location of the guide bar can be changed depending on the size of the workpiece, cutting tool, etc. The clamping device is adjustable in thickness and width of the workpiece. The guide bar 30 is set to process the workpiece at a predetermined size.

The device works as follows.

Conveyor 5 is driven by electric motor 1 through clutch 2, gearbox 3 and chain transmission 4. After adjusting the feed mechanism to a given size, the feed is turned on. In this case, the workpiece is mounted on the conveyor 5 to the stops and is fed to a pressing device. The workpiece, pressing against the flat belt 10, at the entrance to the pressure zone leads the belt, the rollers 13 and the spring-loaded rollers 14 into motion,

Under the influence of the supplied workpiece, the belt and the roller support are bent, and the rollers, when pressed, must be pressed against the two downstream rollers. This is provided by the shaped groove of the rod 22 allowing the rollers to move freely in the horizontal plane, which increases the reliability of operation.

The proposed device provides a more reliable clamping of small and different-thickness blanks in the processing zone, which increases the accuracy and quality of the processed blanks.

Claims (3)
