Description

Double-cutting mechanism for ventilation strips

Technical Field

The utility model relates to an insulating stay technical field especially relates to a ventilation strip double-cutting mechanism.

Background

The air reactor adopts a multi-layer wire parallel structure, a plurality of insulating strips with different quantities are arranged between the wire envelopes along the radial direction, the materials are mainly unsaturated polyester, and insulation and heat dissipation air passages between the envelopes are formed, so that the air reactor is favorable for air convection heat dissipation, and the heat dissipation performance of the air reactor is good. The ventilation strip manufacturers generally form a long ventilation strip and then cut the ventilation strip, and the cutting machine in the prior art is large in size, cannot position the insulation strip, can cut the insulation strip only by holding the insulation strip by hands, and is low in working efficiency and high in labor cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a ventilation strip double-cutting mechanism.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a ventilation strip double-cutting mechanism which characterized in that: the cutting device comprises a support, a cylinder, a swing block, a rotating shaft and two sets of cutter mechanisms, wherein each cutter mechanism comprises a guide rod, a guide block, a pressing plate, a cutter rest and a cutter; the cylinder is fixed the top of support, the piston rod of cylinder with the upper portion of swing piece is articulated through the connecting block, the both ends of pivot are fixed on the support, the middle part of swing piece pass through the bearing with the pivot is connected, the both sides of swing piece respectively with cutter mechanism connects, the both sides of swing piece are equipped with the recess respectively, the guide arm is transversely arranged in the recess, the guide block sets up in the below of swing piece and fixed with the support, the both sides of guide block are equipped with the guide way, two the knife rest is arranged respectively in the guide way rather than sliding fit from top to bottom, the upper portion of knife rest is equipped with the engaging lug, the engaging lug with the both ends of guide arm are connected, the both ends of clamp plate are passed through the bolt fastening and are the guide way lock on the guide block, the cutter is fixed the bottom of knife rest.

Preferably, the swinging block is provided with a bearing inside and is connected with the rotating shaft through the bearing.

Compared with the prior art, the utility model, this device sets up in the top of conveyer belt, and the piston rod of this device cylinder moves forward once and cuts one section, cuts once again after withdrawing, has improved work efficiency greatly.

Detailed Description

Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1-2, a double cutting mechanism for a ventilation strip comprises a bracket 1, a cylinder 2, a swing block 3, a rotating shaft 4 and two sets of cutter mechanisms, wherein each cutter mechanism comprises a guide rod 5, a guide block 6, a pressing plate 7, a cutter rest 8 and a cutter 9; the air cylinder is fixed at the top of the support, a piston rod of the air cylinder is hinged with the upper part of the swing block through a connecting block, two ends of the rotating shaft are fixed on the support, the middle part of the swing block is connected with the rotating shaft through a bearing, two sides of the swing block are respectively connected with the cutter mechanism, two sides of the swing block are respectively provided with a groove 10, the guide rod is transversely arranged in the groove, when the swing block swings left and right, the guide rod can move in the groove to drive a cutter rest below to move up and down, the guide block is arranged below the swing block and is fixed with the support, two sides of the guide block are provided with guide grooves 11 which play a limiting role, two cutter rests are respectively arranged in the guide grooves to be in up-and-down sliding fit with the cutter rests, the upper part of the cutter rests is provided with connecting lugs which are connected with two ends of the guide rod, two ends of the pressing plate are fixed on the guide blocks through bolts to lock the guide grooves, the tool rest is limited through the pressing plate, and the tool rest is convenient to disassemble and assemble. The cutter is fixed at the bottom of the cutter rest. When the cylinder extends out, the cutter on the right side can cut downwards once, the cylinder retracts, and the cutter on the left side can cut downwards once.

When the device is used, the device is arranged above the conveying belt, the piston rod of the cylinder of the device moves forwards to cut one section at a time, and the piston rod is cut once after being withdrawn, so that the working efficiency is greatly improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
