Description

Raw material belt winding drum

Technical Field

The invention relates to the technical field of raw material tape winding equipment, in particular to a raw material tape winding drum.

Background

The raw material belt is an auxiliary article commonly used in liquid pipeline installation, is used for pipeline joints, and enhances the tightness of the pipeline joints. In the prior art, the process of winding the raw material tape to the pipe fitting joint is often manually completed, that is, the raw material tape is gripped and tensioned by hands and then wound on the pipe fitting joint circle by circle, so that an operator is required to have certain operation experience, and obviously the proficiency of the operator can directly influence the quality of the winding process. In other words, the installation quality of the tape is different between different operators and between multiple operations of the same operator, so that the winding consistency of the raw material tape is difficult to guarantee. Meanwhile, professional pipeline maintenance personnel are needed to ensure good pipeline tightness, so that the pipeline maintenance personnel are not beneficial to popularization to common users, and inconvenience is caused to daily use of the common users.

In addition, the raw material belt is of a strip-shaped structure, if the raw material belt is kept smooth in the winding process so as to improve the tightness of the wound raw material belt, the positions gripped by hands are required to be changed alternately along with the winding process, and the continuous reversing of the hands is bound to have pause, which is obviously not beneficial to keeping the tightness of the winding process of the raw material belt; if the raw material belt is required to be continuously wound without stopping after being gripped by hands, the raw material belt can be folded once when rotating for one circle. Obviously, the sealing performance of the raw material tape in a folded state is necessarily reduced. Therefore, the raw material tape of the prior art is wound by a bare-handed method, which inevitably has the technical problems mentioned above, and therefore, the raw material tape of the prior art is installed by a bare-handed winding method, which inevitably has poor tightness.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the utility model provides a raw material area winding cylinder, it can be so that the continuous winding of raw material area is on treating the winding work piece to the raw material area of winding on the work piece is continuous level and smooth, therefore raw material area winding process easy operation, leakproofness are good, the user of being convenient for oneself operates.

The technical scheme adopted by the invention is as follows: the utility model provides a raw material area winding cylinder, including the coiling dish that has central through-hole, be equipped with the annular groove who is used for rolling raw material area on the lateral wall of coiling dish, its characterized in that: the utility model discloses a raw material belt winding device, including annular groove, support ring, coiling disc, raw material belt, material belt head, annular groove endotheca is equipped with two annular support rings, support ring and coiling disc normal running fit, and two support rings set up along the axial interval of coiling disc, the position that lies in between two support rings in the annular groove is equipped with a punishment in advance passageway, punishment in advance passageway and coiling disc's central through-hole intercommunication, the raw material belt is along self length direction rolling on the support ring in the annular groove, just the material of raw material belt head inner circle extends. The common user only needs to overlap the central through hole of coil stock dish on treating the winding work piece, then rotates whole coil stock dish and can make the interior unsintered material area of coil stock dish stretch out and twine in treating the winding work piece from the punishment in the passageway, and whole process need not the taut unsmooth raw material area of gripping that the people's hand lasts to the rotation process of coil stock dish also can keep not stopping in succession, therefore twine the raw material area leakproofness on the work piece well.

The elastic friction block can enable the raw material belt to be tightly attached to a workpiece, and meanwhile, the raw material belt is stretched through the friction resistance between the raw material belt and the elastic friction block, so that the best winding effect is achieved. And increase along with the raw material area number of turns and lead to the increase of external diameter, consequently frictional force between elasticity clutch blocks and the raw material area lasts and risees, and the pivot rotates when frictional force is greater than the static friction between pivot and the coiling dish to make the cutter rotate to the notch position of mounting groove, the knife tip of cutter is located outside the mounting groove from this, and accomplishes the cutting off of raw material area with the contact of raw material area.

And bearings are arranged between the inner side wall of each support ring and the groove bottom of the annular groove, and the support rings are in running fit with the coil trays through the corresponding bearings. The sliding friction of the groove bottom of the annular groove of the winding disc of the inner ring part of the raw material belt can be reduced by arranging the bearing, so that the raw material belt is stretched excessively, and the quality of the raw material belt is influenced.

The bearing is a one-way bearing, and the turnover directions of the two support rings are the same, so that the raw material belt wound on the support rings is continuously conveyed into the central through hole through the material channel. The one-way bearing is arranged, so that a user can rotate towards the correct direction when using the adhesive tape, and the phenomenon that the tape head of the raw material tape is wound in the annular groove due to the fact that the tape head rotates reversely to influence the use of the user is avoided.

The friction force formed by mutually extruding the elastic layers on the two roll shafts can enable the raw material belt to form reverse resistance when being wound on a workpiece to be wound at the same speed, so that the raw material belt always keeps a certain tensioning and stretching state, and the raw material belt wound on the workpiece is enabled to be tighter.

The flexible block is arranged on the rotating shaft, the flexible block is coated outside the cutter, and the elastic friction block and the flexible block are spliced along the circumferential direction of the rotating shaft to form an annular structure. When the rotating shaft is driven to rotate by the friction force between the elastic friction block and the raw material belt, the flexible block coated outside the cutter is in contact with the raw material belt, the elastic force of the flexible block is smaller than that of the elastic friction block on the basis of the same compression amount, so that the tension force on the raw material belt can be reduced, the raw material belt is prevented from being excessively stretched or even broken, and the cutter point of the cutter is sprayed out along with the continuous compression of the flexible block to finish cutting. In the process, the flexible block can prevent the tool nose of the cutter from damaging the raw material belt wound on the workpiece, and the straight raw material belt is compressed by the flexible block in one step to achieve the compression limit position, so that the cutter is cut off the raw material belt, the cutter is prevented from touching the raw material belt along with the rotation of the rotating shaft, and the notch is smooth. The cutting can be performed manually when the user thinks the winding number is enough in daily use. Therefore, the cutter can be used as a standby protection measure to avoid the phenomenon that the coil stock tray is blocked due to the fact that the raw material belt is wound for too many turns.

The elastic friction block and the flexible block are both of fan-shaped structures, and the central angles of the elastic friction block and the flexible block are both 180 degrees.

And the tape head at the outermost ring of the raw material tape is fixedly connected with the adjacent part of the raw material tape.

After adopting the structure, compared with the prior art, the raw material belt winding drum has the following advantages: at first, the central through-hole cover of coiling dish can make the raw material area twine on the work piece through the rotation coiling dish at the uniform velocity on treating the winding work piece, therefore easy operation, the staff of being convenient for uses, and the raw material area is even and be the horizontality at winding in-process, consequently, the raw material area seal after the winding is good, secondly, can make the raw material area receive frictional resistance and stretch at the winding in-process through the roller, consequently, the winding is effectual, at last, support through flexible assembly to lean on can make hugging closely on the surface of work piece that the raw material area can be better, consequently, it is effectual to twine.
