Description

Technical Field

[0001] The utility model relates to the field of mechanical saws, in particular to a mechanical saw with a saw blade that is convenient for replacement. Background Art

[0002] Existing mechanical saws use multiple saw blades to saw at the same time, and can cut a large-sized plate into multiple narrow plates or strips of preset width at one time. Such multi-blade saws generally require relatively economical plate materials, and have the characteristics of small saw paths, thin saw blades, and high smoothness. For example, a device for quickly replacing a multi-blade saw spindle sleeve with publication number CN218947922U includes: a spindle support seat, a spindle and a driving device; the spindle support seat is used to support the spindle, one end of the spindle is rotatably connected to the spindle support seat, and the other end is transmission-connected to the driving device; a spindle sleeve is detachably mounted on the spindle, and a plurality of saw blades are detachably mounted on the spindle sleeve; the spindle is anti-torsionally connected to the spindle sleeve, and the spindle transmits torque to the spindle sleeve.

[0003] When the above device changes the spacing of the saw blades, instead of removing the spindle band saw blades from the machine, the position of each saw blade on the spindle can be directly adjusted according to the width of the floor strip, thereby simplifying the steps. However, if there are too many or too few saw blades on the spindle and it is necessary to reduce or increase the saw blades, the spindle still needs to be disassembled. For this reason, we propose a mechanical saw that is easy to replace saw blades. Utility Model Content
