Description

Technical Field

[0001] The present invention relates to the technical field of cable conduit sealing, and in particular to a tool and method for preparing a strippable variable-diameter module. Background Art

[0002] The peelable reducing module is a mechanical sealing component used to seal the openings where pipes and cables pass through. When it is necessary to seal the opening of a cable or pipe, the peelable reducing module is installed in the opening, and the cable or pipe passes through its center. The rubber part in the peelable reducing module is deformed by mechanical force, thereby pressing the cable or pipe passing through the rubber part to achieve a sealing effect. The core component of the peelable reducing module is the peelable reducing module. The peelable reducing module consists of a U-shaped base and a peelable sheet layer. This peelable reducing module can meet the needs of cooperating with different cable diameters.

[0003] The current method for preparing a peelable variable-diameter module is to prepare a rubber sheet, cut the rubber sheet into a set size, stick the cut rubber sheet layer by layer in a U-shaped frame, and place the frame in a curing tool for curing and molding. This production method requires cutting the rubber sheet into small pieces and then manually sticking them layer by layer in the frame. The production steps are cumbersome and the processing and production speed is slow. Summary of the Invention

[0004] In view of this, the present invention aims to propose a tool and method for preparing a peelable variable-diameter module to solve the problems of complicated production steps and slow processing and production speed of the peelable variable-diameter module in the prior art.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A tool for preparing a peelable variable-diameter module, comprising a bracket and a glue-brushing device, the bracket comprising a first vertical plate, a second vertical plate and a base, the first vertical plate and the second vertical plate being arranged on the base, the bracket being provided with a curling rod and a feed roller, one end of the curling rod being arranged on the first vertical plate, and the other end being arranged on the second vertical plate, one end of the feed roller being arranged on the first vertical plate, and the other end being arranged on the second vertical plate, the feed roller comprising a first feed roller and a second feed roller, the curling rod being arranged between the first feed roller and the second feed roller, the glue-brushing device being used for brushing glue on a rubber sheet, the curling rod being used for rolling the rubber sheet into a peelable variable-diameter module, and the feed roller being used for installing the rubber sheet and conveying the rubber sheet to the curling rod.

[0007] The tooling for preparing the peelable variable-diameter module in the present application is such that the curling rod and the feed roller are both detachably connected to the bracket, which is convenient for disassembly and assembly. When preparing the peelable variable-diameter module, the rubber sheet on the feed roller is wound around the curling rod layer by layer by rotating the curling rod, and glue is applied at the glue application device when the rubber sheet moves from the feed roller to the curling rod. This tooling is convenient for disassembly and assembly, has a fast processing speed and is easy to operate.

[0008] Furthermore, the curling rod includes a first coiling portion, a second coiling portion and a fixing portion, wherein the fixing portion is arranged between the first coiling portion and the second coiling portion, and the fixing portion is used to fix the rubber sheet, and the diameter difference between the first coiling portion and the second coiling portion is equal to the thickness of a single layer of rubber sheet.

[0009] When the diameter of the first roll portion is greater than the diameter of the second roll portion, this structure can ensure that the first layer of rubber sheet close to the first roll portion is the same as the second layer of rubber sheet close to the second roll portion; when the diameter of the second roll portion is greater than the diameter of the first roll portion, this structure can ensure that the second layer of rubber sheet close to the first roll portion is the same as the first layer of rubber sheet close to the second roll portion.

[0010] Furthermore, the fixing portion includes a first fixing portion and a second fixing portion, the first fixing portion is arranged on one side of the curling rod, and the second fixing portion is arranged on the other side of the curling rod.

[0011] This structure is convenient for fixing the rubber sheet.

[0012] Furthermore, the first fixing portion includes a first mounting groove and a first pressing piece, the first pressing piece is arranged in the first mounting groove, and the first pressing piece is detachably connected to the first mounting groove, and the second fixing portion includes a second mounting groove and a second pressing piece, the second pressing piece is arranged in the second mounting groove, and the second pressing piece is detachably connected to the second mounting groove.

[0013] The fixing portion adopts this structure to facilitate fixing the rubber sheet.

[0014] Furthermore, a cutting groove is provided on the curling rod, and the cutting groove includes a first cutting groove, a second cutting groove, a third cutting groove and a fourth cutting groove. The first cutting groove is provided on the left side of the first mounting groove, the second cutting groove is provided on the right side of the first mounting groove, the third cutting groove is provided on the left side of the second mounting groove, and the fourth cutting groove is provided on the right side of the second mounting groove.

[0015] By arranging the cutting groove on the curling rod, after the peelable variable-diameter module is manufactured, it is convenient to cut off the rubber sheet close to the curling rod, thereby taking out the curling rod.

[0016] Furthermore, the tooling also includes a driving portion, which is connected to the curling rod and is used to drive the curling rod to rotate.

[0017] This design has a simple structure and is easy to operate, while also significantly improving production efficiency.

[0018] Furthermore, it also includes a glue brushing device, which is arranged on the left side of the first feed roller or on the right side of the second feed roller.

[0019] During the process of rolling the peelable variable-diameter module with a curling rod, the surface of the rubber sheet is brushed with glue through a glue brushing device, which can make the adjacent rubber sheets in the peelable variable-diameter module fit tightly together and enhance the adhesion consistency between the adjacent rubber sheets in the peelable variable-diameter module.

[0020] Furthermore, a mounting portion is provided on the feed roller, and the mounting portion is used to install the rubber sheet. The mounting portion includes a first mounting portion and a second mounting portion. The first mounting portion is provided on the first feed roller, and the second mounting portion is provided on the second feed roller.

[0021] The diameter of the mounting portion is smaller than the diameter of the two ends of the feed roller. This structure facilitates the fixing of the rubber sheet. During the process of the feed roller feeding the material to the curling rod, the rubber sheet will not move toward the two ends of the feed roller, thereby ensuring that the feed roller can feed the material to the curling rod smoothly and improving the manufacturing accuracy of the peelable variable diameter module.

[0022] The present invention also provides a method for preparing a peelable variable-diameter module based on the above-mentioned tooling, comprising:

[0027] S5: After curing for t1, use a cutting tool to cut off the innermost layer of rubber sheet close to the curling rod through the cutting groove, and then take out the curling rod;

[0028] S6: Divide the peelable variable diameter module into a first peelable variable diameter module and a second peelable variable diameter module along the line connecting the upper and lower midpoints of the front end and the rear end of the curling rod, wherein the first peelable variable diameter module is located on one side of the first coiling part and the second peelable variable diameter module is located on one side of the second coiling part.

[0029] The method for preparing the peelable variable-diameter module in the present application is not only simple to operate but also has high production efficiency and can significantly reduce labor costs.

[0032] 1) The drive unit drives the curling rod to rotate, and the feed roller continuously feeds the material to the curling rod, which can greatly improve the processing efficiency and reduce labor costs;

[0033] 2) The difference in diameter between the first coiled portion and the second coiled portion is equal to the thickness of a single layer of rubber sheet, so as to facilitate the control of the first and second peelable variable diameter modules to have the same diameter and color;
