Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane preparation technology, and in particular to a waterproof membrane edge trimming device. Background Technology

[0002] Waterproof membrane refers to a waterproof material product made by impregnating a base material with asphalt or polymer waterproof materials. Because it appears in the form of a roll, it is called waterproof membrane.

[0003] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up.

[0004] After the waterproof membrane is formed, burrs will remain on the edges, resulting in uneven dimensions. Generally, an edge trimming machine is used to trim the edges of the waterproof membrane.

[0005] In existing edge trimming machines, the cutting device has a fixed blade position. Usually, the blade tip or blade edge is fixed in position to cut the roll material. After long-term cutting, the corresponding part of the blade will wear, thus affecting the cutting performance. As for the blade, it is only a local part that is damaged, and directly discarding and replacing it would be a waste of resources. Utility Model Content

[0007] The technical solution of this utility model is as follows: A waterproof membrane edge trimming device includes a frame, a cutting assembly located at the upper middle part of the frame for cutting the edge of the waterproof membrane, a flattening unit located at the upper right side of the frame, and a winding unit located at the left side of the frame; the cutting assembly includes a support plate located at the middle part of the frame, a pair of slidably symmetrically arranged transverse columns at both ends of the support plate, a cutting unit correspondingly located inside each support plate, a transverse unit that drives the transverse columns to move synchronously, and a reciprocating unit that drives the cutting unit to reciprocate up and down; the transverse unit includes a drive rod arranged along the length direction of the support plate and rotatably connected to the two transverse columns, a handwheel located at one end of the drive rod and driving the drive rod to rotate, and a limiting seat correspondingly located on the frame; the drive rod can rotatably pass through the limiting seat, and two sections of external threads with opposite directions are distributed along the middle part of the outer periphery of the drive rod.

[0008] In the aforementioned waterproof membrane trimming device, the reciprocating unit includes a reciprocating motor, a cam connected to the output shaft of the reciprocating motor, a limiting post corresponding to one side of the reciprocating motor, and a lifting post that can be lifted and moved and sleeved in the limiting post; the cutting unit is detachably installed on the top of the lifting post.

[0009] In the aforementioned waterproof membrane trimming device, a reciprocating groove is provided on one side of the limiting column, and a reciprocating push rod that passes horizontally through the reciprocating groove is connected to one side of the lifting column; the reciprocating push rod abuts against the cam and is located above the cam.

[0011] In the aforementioned waterproof membrane trimming device, a spring plate is provided on the outside of the lifting column, a vertical slot corresponding to the spring plate is provided inside the limiting column, and a compression spring is provided inside the limiting column to abut against the top of the spring plate.

[0012] In the aforementioned waterproof membrane trimming device, the flattening unit includes a pair of mounting vertical plates and two corresponding horizontally rotating pressure rollers disposed between the mounting vertical plates; the pressure rollers include an upper pressure roller at the top and a corresponding lower pressure roller at the bottom, and there is a certain gap between the upper pressure roller and the lower pressure roller.

The cutting assembly includes a support plate, a drive rod, a transverse column that can be moved laterally on the drive rod, a cutting unit for cutting the roll material and a reciprocating unit for driving the cutting unit to move back and forth.
