Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, in particular to a cold-wrap waste edge winding device. Background Art

[0002] Cold wrapping tape refers to adhesive tape used for anti-corrosion wrapping. Cold wrapping tape is suitable for the anti-corrosion and repair of straight pipes, elbows, storage tanks, guides and other parts of oil, natural gas, chemical industry, water supply and drainage. When producing cold wrapping tape, it is generally necessary to carry out the extrusion and extension step of the mixed rubber, and extrude it through an extruder to achieve the required thickness and width. After extrusion and extension, the edges of the cold wrapping tape will be uneven. The uneven edges of the cold wrapping tape not only affect the appearance, but also easily curl up during storage or transportation, causing dust and impurities to enter and contaminate the adhesive surface of the tape, causing the adhesive surface to lose its stickiness.

[0003] Usually, when the cold wrap is extruded, a cutting knife is used to cut the two sides of the formed cold wrap. The cut waste edges need to be collected by the winding equipment to facilitate subsequent unified processing. In order to ensure uniform winding, traditional winding equipment generally uses a swing rod or other horizontal reciprocating moving mechanism to move the waste edges back and forth, and then evenly wind them on the winding drum. However, the width of the waste edges of the cold wrap is not fixed, and some are wide and some are narrow. When the width of the waste edges changes, the swing rod or other horizontal reciprocating moving mechanism also needs to adjust the size of the channel for the waste edges to ensure that the waste edges can be evenly wound on the winding drum. This kind of horizontal reciprocating moving mechanism needs to stop every time to adjust the channel size, which is inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a cold-wrap waste edge winding device to solve the problem that the transverse reciprocating moving mechanism on the traditional winding device needs to stop each time to adjust the channel size, which is troublesome to use.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A cold-wrap waste edge winding device comprises a frame, a reciprocating mechanism, a winding assembly and a cylinder. The reciprocating mechanism is mounted on the frame, the winding assembly is mounted on the movable end of the reciprocating mechanism, and the cylinder is symmetrically arranged and respectively mounted on the rotating ends of the winding assembly.

[0007] A further technical solution is: the reciprocating mechanism includes a first motor, a sector gear, a bar frame, a load-bearing plate and a slide, the first motor and the load-bearing plate are both installed on the frame, the slide is slidably installed on the load-bearing plate, the bar frame is installed on the bottom of the slide, the sector gear is installed on the output end of the first motor, and racks that are compatible with the sector gear are symmetrically arranged in the bar frame.

[0008] A further technical solution is that the arc length of the sector gear is consistent with the length of the cylinder.

[0009] A further technical solution is that the arc length of the sector gear does not exceed half of its circumference.

[0010] A further technical solution is: the winding assembly includes a second motor, a rotating shaft and a square shaft, the rotating shaft is rotatably mounted on the slide, the second motor is mounted on the slide, and the second motor drives the rotating shaft to rotate, the square shaft is respectively mounted at both ends of the rotating shaft, the cylinder is slidably mounted on the square shaft, and the cylinder 4 is locked with the square shaft 13 by bolts.

[0011] A further technical solution is that baffles are installed on both sides of the cylinder through bolts.

[0012] A further technical solution is: a sleeve is slidably mounted on the cylinder.
