Description

TECHNICAL FIELD

[0001] The present application relates to the field of hoisting and lifting, in particular to a round belt winding machine and a winding method. BACKGROUND

[0002] Rigging is mainly divided into metal material rigging and fiber soft rigging according to materials. The round belt is a widely used fiber soft rigging mainly used for hoisting and lifting, and the main manufacturing materials include polyester and polypropylene fiber filaments. The round belt is made by winding one or more fiber filaments in N turns to form a round shape, and then wrapping a protective layer of belt skin outside the round fiber. This soft rigging has many advantages such as light weight, soft texture, wear resistance, corrosion resistance, easy storage and easy maintenance, and has a wide application market.

[0003] Generally, the production principle of the round belt includes a driving pulley and a driven pulley. A bundle of fiber filaments is wound on the two pulleys, and the filament ring is threaded on a cylindrical belt sheath. The two pulleys are rotated to drive the filament to be wound in N turns to form a ring.

[0004] In fact, the above process has the following problems: as the number of winding turns increases, the fiber filaments are stacked layer by layer on the two pulleys, so that the length of the inner layer of filaments wound on the pulley is less than the length of the outer layer of filaments wound on the pulley, resulting in inherent errors between the inner and outer layers. As the number of winding layers increases, the error range becomes larger and larger. Some filaments gradually tighten due to position changes, and the tension becomes larger. Some filaments appear obvious relaxation. Finally, although the amount of material wound increases, the breaking tension does not improve, and the material utilization rate is low. At present, only round belts below 3 tons are suitable for the above production method. Round belts above 3 tons have the problem of low material utilization rate, and as the number of winding turns of the round belt increases, the utilization rate shows an accelerating downward trend. Therefore, in the production of round belts above 20 tons, only manual winding can be used. SUMMARY

DETAILED DESCRIPTION

[0028] In the following, in order to facilitate the understanding of the technical scheme of the application by those skilled in the art, further description will be made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the application.

[0029] In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the application. However, it is apparent that one or more embodiments can be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessary confusion of the concept of the application.

[0030] As Figure 1As shown, the circular band winding machine provided by the present application comprises a rack 1, a driving I-beam 2 and a driven I-beam 3 are installed on the rack 1 in parallel, the driving I-beam 2 is fixedly connected to one end of the rack 1, the driven I-beam 3 is positioned on the rack 1 through a positioning pin, and the driven I-beam 3 is in sliding connection with the rack 1 for adjusting the size of the circular sleeve to be produced. The driven I-beam 3 is connected with a spring advancing and retreating device 4, a bundle splitting device 5 is symmetrically arranged on the driving I-beam 2 and the driven I-beam 3, a wire bundle 6 is split and wound in the bundle splitting device 5 to form a plurality of wire bundles with the same diameter, so that in the production process of the large-tonnage circular band, the wire bundles with the same diameter are continuously produced and wound.

[0031] As shown in the figure, Figure 2 The bundle splitting device 5 is a multi-layer winding groove 51 arranged at intervals on the driving I-beam 2 and the driven I-beam 3, which divides the driving I-beam 2 and the driven I-beam 3 into multiple parts to form a "tower-like" shape. The width of the winding groove 51 is equal, and the driven I-beam will displace a certain distance X under the action of the spring advancing and retreating device 4 after being bound by the pressing force of the wire bundle, so that the center distance between the driving I-beam and the driven I-beam is reduced. Therefore, in order to make the length of the second winding adjacent to the first winding infinitely close to the actual length of the first winding, the diameter of the second winding adjacent to the first winding needs to be increased to compensate for the shrinkage caused by the displacement X of the driven I-beam. The diameter of the winding groove 51 increases from inside to outside, and the diameter increase Y is equal to the displacement X of the driven I-beam 3 driven by the spring advancing and retreating device 4, that is, equal to the length of the center distance reduction between the driving I-beam and the driven I-beam, so as to ensure that the actual length of the wire bundle 66 wound in each layer of the winding groove 51 is consistent. At the same time, the diameters of the winding grooves 51 on each layer of the driving I-beam 2 and the driven I-beam 3 are equal, which ensures the uniform distribution of the wire bundle before and after.

[0032] The driving I-beam 2 and the driven I-beam 3 are wound with a plurality of wire bundles 6 on the same layer of the winding groove 51, and the number of wire bundles 6 in each layer of the winding groove 51 is the same, which ensures that the circular band is always under constant tension control during the winding process, so that the diameters of the small-tonnage wire bundles formed are equal and the stress is uniform.

[0033] As shown in the figure, Figure 3As shown, the spring advance / retreat device 4 includes a motor 41, a chain drive mechanism 42, a screw 43, a connecting block 44, a right-angled curved arm 45, a horizontally arranged connecting shaft 46, a spring 47, a guide rail 48, and a mounting positioning plate 49. The motor 41 is connected to the screw 43 via the chain drive mechanism 42. One end of the connecting shaft 46 passes through the connecting block 44 and is connected to one end of the curved arm 45. The other end of the connecting shaft 46 is fitted with a washer 40 and locked with a nut. The front side of the other end of the curved arm 45 is fixed to the axle of the driven I-beam wheel 3. The mounting positioning plate 49 is connected to the frame 1. The rear side of the guide rail 48 is fixed to the mounting positioning plate 49. The curved arm 45 is slidably connected to the guide rail 48. The spring 47 is fitted onto the connecting shaft 46. One end of the spring 47 abuts against the washer 40, and the other end of the spring 47 abuts against the end face of the connecting block 44. The motor of the driven I-beam 3 drives the screw 43 to rotate through the chain transmission mechanism 42, which in turn drives the connecting block 44 to move left and right. The driven I-beam 3 is integrated with the crank arm 45 and the spring 47 and moves along the guide rail 48. When the driven I-beam 3 is subjected to force and the connecting block 44 is stationary, the spring 47 is compressed, and only the crank arm 45 and the driven I-beam 3 move to the left.

[0034] like Figure 2 As shown, in this device, a counting device 7 and a winding device 8 are sequentially arranged on the base 1 near the driving I-beam 2. The counting device 7 is electrically connected to a PLC, which is used to count the number of turns of the incoming wire bundle 6. When the counting device 7 senses the magnetic sheet, it transmits a signal to the PLC program to record it as one turn. The winding device 8 includes a cycloidal I-beam 81 and a stepper drive device 82. The cycloidal I-beam 81 is threaded onto the stepper drive device 82, which is electrically connected to the PLC. In the initial state, the cycloidal I-beam 81 is parallel to the innermost winding groove 51 of the driving I-beam. When winding begins, the incoming wire bundle 6 passes through the counting device 7 and the cycloidal I-beam 81 in sequence and enters the winding groove 51 of the driving I-beam 2 and the driven I-beam 3 for winding. When the number of winding turns reaches the predetermined number N, the PLC program sends a signal, and the PLC controls the stepper drive device to start, driving the cycloidal I-beam 81 to move the incoming wire bundle 6 to change the winding groove. The number of winding turns N is set according to the number of winding wheel grooves evenly distributed throughout the entire annular belt. For example, assuming the total number of winding turns required for the annular belt is 500 turns and the winding wheel groove 51 is set to a 5-layer structure, then the predetermined number of turns N in each layer of winding wheel groove 51 is 100 turns.

[0035] The present application is a circular band winding machine. The present application is characterized in that the symmetrically arranged filament stock device 5 in the prior art active I-beam 2 and driven I-beam 3 is used to wind the incoming filament 6. The large tonnage circular band is decomposed into multiple small tonnage filament rings with the same diameter through continuous production, which reduces the number of winding layers and the diameter error caused by the increase of the number of winding layers. On the other hand, the circular band is always under constant tension control during the winding process, and the stress of the small tonnage filament ring is uniform, thereby improving the overall strength of the circular band and reducing the obvious relaxation of the partial filament. The present application can significantly reduce the cost and increase the benefit for the production of circular bands with a length of more than 5 tons, especially for the production of large tonnage circular bands with a length of 20 to 50 tons. The diameter of the winding wheel groove 51 increases from inside to outside, and the diameter increase is compensated by the displacement of the driven I-beam 2 under the drive of the spring advancing and retreating device 4, which ensures the consistency of the actual length of the filament wound in each layer of the winding wheel groove 51, improves the material utilization rate, and reduces the production cost of the product. The present application realizes automatic counting and automatic filament control, reduces labor intensity, saves labor, and is suitable for popularization and use.

[0036] The present application also provides a circular band filament winding method using the present circular band winding machine, comprising the following steps:

[0037] Step one: pass the incoming filament 6 through the sheath 9 in the laminated state, and wind it around the innermost winding wheel groove 51 of the active I-beam 2 and the driven I-beam 3 respectively for one turn, and finally tie the end of the incoming filament 6 to the filament ring at the innermost winding wheel groove 51;

[0038] Step two: move the driven I-beam 3 to the right to form a tight filament ring;

[0039] Step three: start the drive motor of the active I-beam 2, and the incoming filament 6 is continuously wound to form a filament ring. During rotation, the inner circle of the filament ring rubs in the winding wheel groove 51 of the active I-beam 2 and the driven I-beam 3, respectively, and the friction force drives the incoming filament 6 to continuously wind;

[0040] Step four: after winding N turns, the counting device 7 monitors the number of winding turns to reach the predetermined value, and the PLC drives the cycloid I-beam 81 to move the incoming filament 6, which enters the next layer of winding wheel groove 51 of the active I-beam 2 and the driven I-beam 3 to continue winding N turns to form a new filament ring;

[0041] Step five: repeat S4 operation until the incoming wire bundle 6 enters the outermost winding groove 51 of the driving spool 2 and the driven spool 3 and is wound N turns, then cut the incoming wire bundle 6 and tie it in the layer of wire bundle ring;

[0042] Step six: pull the sheath 9 apart and sew together the wire bundle rings wound in each layer of winding groove together with the processed, the toroidal tape processing is completed;

[0043] Step seven: move the driven spool 3 to the left, remove the toroidal tape, and complete the production process.

[0044] The present application adopts the winding method of the toroidal tape winding machine, and the incoming wire bundle 6 is wound in the corresponding winding groove 51 of the driving spool 2 and the driven spool 3. In the large-tonnage toroidal tape production process, a plurality of small-tonnage wire bundle rings of the same diameter are continuously produced, so that the length of each turn of the wire bundle is the same, the comprehensive utilization rate of the wire bundle is improved, the product cost is reduced, and the production efficiency is improved.

[0045] The above embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application.
