Description

Technical Field

[0001] This utility model relates to the field of roll material winding technology, specifically a high-efficiency cutting and winding device for waterproof roll materials. Background Technology

[0002] Waterproof membrane refers to a waterproof material product made by impregnating a base material with asphalt or polymer-based waterproofing materials. It is supplied in roll form and is called waterproof membrane. It is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. It is a flexible building material that can be rolled up and serves as a leak-proof connection between the foundation and the building. It is the first line of defense for waterproofing the entire project and plays a vital role in the overall project.

[0003] As indicated in announcement number CN 215159508 U, a waterproof membrane production winding device is described. This device includes a winding side plate, a support plate provided on the lower middle part of the winding side plate, and a compression spring installed above the support plate. A compression plate is fixed above the compression spring and simultaneously compresses the waterproof membrane during winding to prevent large gaps from forming between rolls during the winding process, which would cause the membrane to loosen. The device can also cut the waterproof membrane as needed.

[0004] When the above-mentioned device is in use, the roll material needs to be cut after it is wound up, and then the take-up roller is replaced for rewinding. At this time, the cut end of the roll material is prone to shifting or loosening, which makes it inconvenient for workers to rewind. The take-up roller is also not easy to pick up and replace. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency cutting and winding device for waterproof membranes, so as to solve the problem in the background art that after the membrane is wound up, it needs to be cut and then rewound with a winding roller. At this time, the cut end of the membrane is prone to shifting or loosening, which makes it inconvenient for workers to rewind it, and the winding roller is also inconvenient to pick up and replace.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cutting and winding device for waterproof membrane, including a side frame, and two sets of side frames are symmetrically arranged;

[0007] Also includes:

[0008] A take-up roller is installed between two side frames. Clamping plates are installed on the inner sides of the two side frames, and two sets of clamping plates are symmetrically arranged. The inner surface of the clamping plate away from the take-up roller has a flat surface, and the two flat surfaces are parallel to each other. The inner surface of the clamping plate near the take-up roller has an inclined surface. A cutting blade is provided on the inner side of the clamping plate near the take-up roller, and the cutting blade is located at one end of the inclined surface. The surface of the side frame is provided with a sliding groove, and the sliding groove connects the inner and outer sides of the side frame. Slider blocks are symmetrically arranged on the outer side of the clamping plate, and the sliders slide and engage inside the sliding groove.

[0009] Preferably, two sets of fixing brackets are symmetrically arranged at both ends of the outer side of the slide groove. A bidirectional screw is installed between one set of fixing brackets, and the slider at the corresponding position is threadedly connected to the bidirectional screw through a threaded hole on the surface. One end of the bidirectional screw is connected to a second motor, and the second motor is located at the upper end of the fixing bracket at the corresponding position.

[0010] Preferably, a sliding rod is provided between the other set of fixing frames, and the slider at the corresponding position is slidably engaged with the sliding rod through a round hole on the surface.

[0011] Preferably, a rotating disk is provided on the inner side of one of the side frames, and a first motor is provided on the outer side of the corresponding side frame, and the first motor is connected to the rotating disk. A first engaging groove is provided on the inner side of the rotating disk, and a first connecting block is provided at one end of the take-up roller near the rotating disk, and the first connecting block is movably engaged inside the first engaging groove.

[0012] Preferably, a limiting plate is provided on the inner side of the other side frame, and a second engaging groove is provided on the inner side of the limiting plate. A second connecting block is provided at one end of the take-up roller near the limiting plate, and the second connecting block is movably engaged inside the second engaging groove.

[0013] Preferably, a rotating rod is provided on the inner side of the side frame, and the rotating rod rotates on the inner side of the side frame via a rotating shaft. A movable groove is provided on the side of the limiting plate near the rotating rod, and the front end of the rotating rod is movably engaged inside the movable groove. A limiting piece is provided on the rear end surface of the rotating rod, and a spring is provided on the surface of the rotating rod, with the two ends of the spring abutting between the limiting piece and the limiting plate, respectively.

[0014] Preferably, a limiting roller is provided on one side of the two side frames near the flat surface, and the limiting roller rotates via a rotating shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Through the clamping structure, the end of the roll material passes through the clamping plates and is wound around the surface of the take-up roller. The take-up roller is driven by a motor to rotate and take up the roll material. After the take-up roller has finished taking up the roll material, the motor drives the bidirectional screw to rotate and drive the two clamping plates to close at the same time. The flat surfaces of the clamping plates are used to clamp the roll material. When the clamping plates are closed, the cutting blade can cut the roll material. At this time, the take-up roller can be taken out and replaced. The cut roll material is fixed inside by the clamping plates. After replacing the take-up roller, the clamping plates are raised. The operator can take out the subsequent roll material from the inclined surface and extend the roll material to rewind it onto the take-up roller for subsequent winding work. The clamping plates can clamp the roll material behind while cutting the roll material, which is convenient to prevent the roll material from shrinking or shifting when replacing the take-up roller.

[0017] (2) When it is necessary to remove the take-up roller, press the take-up roller forcefully towards the limiting plate, so that the limiting plate slides towards the rotating rod. At this time, the first connecting block at the other end of the take-up roller will slide out from the first engaging groove in the rotating plate, so that the take-up roller can be picked up and quickly replaced. The method for installing the take-up roller is the same. The limiting plate is held in place by the spring, and the engaged take-up roller is limited. This method can quickly install and remove the take-up roller without affecting the rotation of the take-up roller. Attached Figure Description
