Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, the gear-driven double-saw-blade cutting device disclosed in this embodiment is used for solving the problem that, in the cutting tool with the existing double-saw-blade structure, two independent motors are mostly adopted to respectively drive and cut two sets of saw blades, which results in large energy consumption and noise.

The gear transmission double-saw-blade cutting device is provided with a motor 3, a driving wheel 4, a workbench 2 and a frame 1, wherein the workbench 2 is installed at the top of the frame 1, the motor 3 and the driving wheel 4 are arranged below the workbench 2, the driving wheel 4 is provided with a forward cutting saw blade 5 through a driving shaft, and the structure of the part is similar to that of the existing single-saw-blade cutting saw, and the detailed description is omitted.

Set up the saw bit mouth that corresponds with the saw bit on workstation 2, supply forward cutting saw bit 5, backward cutting saw bit 11 stretches out from the lower part, 2 workstation below of workstation is equipped with first from driving wheel 6, first from driving wheel 6 side is equipped with first gear 7, first from driving wheel 6 and first gear 7 all install on first driven shaft 8, 6 side of first gear sets up the second gear 9 of meshing, second gear 9 passes through the driven backward cutting saw bit 11 of second driven shaft 10 installation, the cover is equipped with belt 12 on action wheel 4 and the first driven wheel 7 of following, the height that the workstation was stretched out to forward cutting saw bit 5 is greater than the height that backward cutting saw bit 11 stretched out the workstation. And both are arranged in the same vertical plane.

Specifically, when the gear transmission double-saw-blade cutting device works, cutting materials such as a finish paint plate and the like are placed on the workbench 2 and then pushed to move towards the reverse cutting saw 11 and the forward cutting saw blade 5, the motor 3 works to drive the driving wheel 4 to rotate, and the driving wheel 4 drives the first driven wheel 6 and the first gear 7 to move through transmission parts such as a belt and the like.

Since the first gear 7 and the second gear 9 are engaged, the second gear 9 rotates in the opposite direction and synchronously drives the reverse cutting blade 11 to rotate.

The reverse cutting saw blade 11 firstly cuts the painted surface of the bottom surface of the material 19, and the painted surface faces the reverse cutting saw blade 11, so that the primer surface of the material 19 can be prevented from paint collapse, and meanwhile, the reverse cutting saw blade 11 cannot cut the painted surface of the material because the cutting height is lower than the thickness of the material; then, when the cutting material moves into contact with the forward cutting blade 5, the painted surface faces the forward cutting blade 5, so that the painted surface does not collapse.

Moreover, since the primer surface is cut first, the forward cutting saw blade 5 cannot cut the primer surface at this time, and finally, the paint can be prevented from being cracked on the upper paint surface and the primer surface of the cutting material 19, so that the cutting quality is improved. Because the motor 3 is used for driving the opposite cutting of the double saw blades, the device can reduce the power consumption, the volume and the weight and reduce the production cost.

The specific implementation materials and modes are selected by taking the drawing of the specification as a drawing, the implementation is carried out according to the proportion and the matching mode of each part in the drawing of the specification, the common connection modes such as strong adhesive connection, welding, riveting connection, integral forming type connection and the like are adopted, and the corresponding connection mode, the thickness and the strength of the connection point can be selected creatively according to the actual connection strength requirement during actual manufacture.

As shown in fig. 1, in the present embodiment, in order to save the equipment space at the lower part of the working table 2, facilitate the assembly of parts and safe use, the first gear 7 is disposed between the driving wheel 4 and the second gear 9. The first gear 9 is provided inside the first driven wheel 6. The first driven shaft 8 and the second driven shaft 10 are both installed on a vertical bottom plate or a workbench, and the vertical bottom plate is fixed with the rack.

As shown in fig. 2, the second driven shaft 10 is provided with an elevation adjustment mechanism according to the present embodiment. This lift adjustment mechanism includes guide holder 13, fixing base 14, screw rod 16 and lifting bolt 17, guide holder 13 is installed in frame 1, open the arc spout on the guide holder 13, middle part suit adjusting bearing behind the arc spout is passed to second driven shaft 10, adjusting bearing is connected with 16 upper ends of screw rod, fixing base 14 is passed to 16 lower extremes of screw rod, the fixing base is articulated with frame 1 through round pin axle 18, set up lifting bolt 17 on the screw rod 16, can adjust the position of second driven shaft 10 through lifting bolt 17, thereby it reciprocates to drive reverse cutting saw bit 5. Ensuring the driving force and the cutting effect of the second driven shaft 10 driving the backward cutting saw blade 11,

the technical contents not described in detail in the present invention are all known techniques.
