Description

Technical Field

[0001] This utility model relates to a three-strand rope twisting machine, and more particularly to an ultra-long rope twisting machine with an adjustable yarn container diameter. Background Technology

[0002] In rural northern China, every household relies on three-strand ropes throughout the year for harvesting and planting crops. Three-strand ropes are not only widely used in rural areas, but also as brake ropes for agricultural machinery, film-pressing ropes for vegetable greenhouses, climbing ropes, tarpaulin binding ropes for large trucks, and industrial binding ropes.

[0003] Currently, most three-strand ropes on the market are produced by three-strand rope twisting machines with relatively simple structures. The three-strand rope twisting machines commonly used in rope workshops have the following disadvantages: when twisting ultra-long ropes exceeding two thousand meters, it is necessary to increase the yarn storage capacity. Existing technology basically increases the yarn storage capacity by increasing the diameter of the yarn container, but this will cause the large-diameter yarn container to intersect with the main shaft during machine operation, resulting in interference.

[0004] Furthermore, existing three-strand rope twisting machines use gear meshing transmission. To eliminate interference caused by increasing the diameter of the yarn container, the meshing gears must be disengaged, preventing them from meshing and thus disrupting the gear meshing transmission system. Therefore, it is difficult to increase the yarn storage capacity of a single existing three-strand rope twisting machine by increasing the diameter of the yarn container. Rope workshops often need to purchase multiple models of three-strand rope twisting machines to meet customers' needs for different lengths and sizes of three-strand ropes, resulting in excessive costs and large equipment footprints.

[0005] Therefore, there is an urgent need for a three-strand rope twisting machine that can freely change the diameter of the yarn container to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing three-strand rope twisting machines cannot increase the yarn storage capacity by increasing the diameter of the yarn container, thus making it impossible to twist ultra-long ropes.

A slider that engages with the lead screw helical drive and slides with the guide shaft; A wire spool shaft is vertically mounted on the slider, and a twisting grooved wheel is sleeved on the wire spool shaft and can rotate with it; the twisting grooved wheel is connected to a main shaft fixed wheel fixed on the main shaft axis via a belt; The yarn container is mounted on the yarn spool or the twisting grooved wheel.

[0008] In a preferred embodiment of the present invention, the yarn carrier includes a spindle base plate and a spindle mounted thereon; the spindle base plate is sleeved and fixed to the yarn reel shaft via a yarn reel seat.

[0009] In a preferred embodiment of this utility model, the yarn container is a yarn tray; the yarn tray is fixedly mounted on the twisting groove wheel via a yarn spool seat and rotates together with the twisting groove wheel.

[0010] In a preferred embodiment of the present invention, the transmission system includes a central grooved wheel connected to the drive pulley via a belt, the central grooved wheel being coaxially and fixedly connected to the central rotating disk for driving the central rotating disk to revolve.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figure 1The existing three-strand twisting machine specifically includes: a rotating disk 101, a fixed gear 102, an upper intermediate wheel shaft 103, a twisting disc intermediate gear 104, a twisting gear shaft 105, a spindle seat disk 106, a twisting gear 107, an intermediate gear 108, a first bearing 109, an intermediate shaft 110, a rotating disk intermediate gear 111, a lower intermediate wheel shaft 112, an upper bevel gear 113, a lower bevel gear 114, a power unit 115, a drive pulley 116, a take-up pulley 117, a drive gear 118, a lower disk 119, a spindle 120, a driven pulley 121, a bracket 122, a support column 123, and a main shaft 139. Its transmission mode is a traditional gear meshing transmission, and it is not possible to change the yarn container of different diameters according to production needs.

[0020] This invention provides an ultra-long rope twisting machine with an adjustable yarn container diameter.

[0021] First embodiment, such as Figures 2 to 5 As shown, the rope twisting machine includes a frame, which mainly consists of a horizontally arranged lower plate 119, a support 122 located above it, and several support columns 123 connecting the two. On the support 122, there is an active pulley 116 driven by a power unit 115 and a take-up pulley 117 for winding the final twisted rope.

[0022] The core improvement of this embodiment lies in the spindle seat moving device and rotating system. Specifically, a main shaft fixed wheel 134 is fixedly installed at the center of the frame, and a central grooved wheel 137 is connected to the drive pulley 116 via a belt. A central rotating disk 130 is coaxially and fastened below the central grooved wheel 137, so that the central rotating disk 130 can revolve around the main shaft fixed wheel 134 fixed on the axis of the main shaft 139 under the drive of the power device 115.

[0023] The ingot seat moving device is installed on the upper surface of the central rotating disk 130. It includes two lead screw bearings 127 fixed to the edge of the central rotating disk 130 by bolts 136. Between the two lead screw bearings 127, a lead screw 124 and two guide shafts 126 are mounted in parallel. The two ends of the lead screw 124 are supported on the lead screw bearings 127 by rolling bearings 129. One end of the lead screw 124 extends and is fixedly connected to a handwheel 128. The ends of the two guide shafts 126 are directly fixedly connected to the lead screw bearings 127 by bolts 136. A slider 125 forms a helical drive with the lead screw 124. At the same time, the guide hole on the slider 125 forms a sliding fit with the two guide shafts 126, ensuring that the slider 125 can only move smoothly along the axial direction of the guide shafts 126 (i.e., the radial direction of the central rotating disk 130).

[0024] A spool shaft 131 is vertically fixed to the bottom of the slider 125 by bolts 136. A twisting groove wheel 135 is fitted in the middle of the spool shaft 131. The twisting groove wheel 135 is connected to the fixed main shaft wheel 134 by an annular belt to form a planetary gear train.

[0025] In this embodiment, the yarn carrier container is a spindle 120 and a spindle base plate 106. Multiple spindles 120 (multiple are shown in the figure, but the actual number can be set as needed) are evenly installed on the spindle base plate 106. The center of the spindle base plate 106 is fitted and fixed to the top of the spindle shaft 131 through a spool seat 133, so that the entire yarn carrier container (spindle base plate 106 and spindle 120) together with the spindle shaft 131, the twisting groove wheel 135 and the slider 125 form a synchronously movable whole.

[0026] Working principle and adjustment process: During operation, the power unit 115 drives the central grooved wheel 137 via a belt, causing the entire central rotating disk 130 and all its components to revolve around the main shaft fixed wheel 134. At the same time, since the twisting grooved wheel 135 is connected to the fixed main shaft fixed wheel 134 via a belt, it will rotate on its own axis while revolving. This rotation is transmitted to the spindle seat disk 106 through the yarn reel shaft 131 and the yarn reel seat 133, driving the spindle 120 to rotate around its own axis, thereby twisting the yarn. When it is necessary to adjust the twist pitch or tension of the cable, the operator turns the handwheel 128. The handwheel 128 drives the lead screw 124 to rotate, driving the slider 125 to move linearly along the guide shaft 126. Since the yarn container (spindle seat disk 106 and spindle 120) is installed on the slider 125, its revolution radius changes accordingly. When moving forward (towards the center), the revolution radius decreases, and when moving backward (outwards), the revolution radius increases, realizing online stepless adjustment.

[0027] Second embodiment, such as Figure 6 , Figure 7 As shown, this embodiment provides an ultra-long rope twisting machine that uses a yarn tray 132 as a yarn container. Its overall frame, power transmission (power unit 115, drive belt pulley 116, take-up reel 117), driving method of the central rotating disk 130 (central grooved wheel 137), and specific composition of the spindle seat moving device (including lead screw shaft seat 127, lead screw 124, guide shaft 126, handwheel 128, bearing 129, slider 125, bolt 136, and yarn reel shaft 131) are all the same as those in Embodiment 1, so they will not be described again here.

[0028] The main difference between this embodiment and the first embodiment lies in the specific form and installation method of the yarn-carrying container.

[0029] In this embodiment, the yarn container is a yarn tray 132 that directly supports the yarn bobbin. The yarn tray 132 is directly fixed to the upper surface or side of the twisting groove wheel 135 through a spool seat 133 and rotates synchronously with the twisting groove wheel 135. That is, the yarn tray 132, the spool seat 133 and the twisting groove wheel 135 are fixed together as a rotating body. The rotating body is sleeved on the spool shaft 131 through its central hole and can rotate freely around the spool shaft 131, but its radial position is determined by the slider 125.

[0030] Working principle and adjustment process: The basic twisting and adjustment principle of the second embodiment is the same as that of the first embodiment. The power device 115 drives the central rotating disk 130 to revolve. The belt drive between the fixed main shaft fixed wheel 134 and the twisting groove wheel 135 drives the yarn carrier disk 132 to rotate, completing the twisting process. When the handwheel 128 is turned, the slider 125 is driven to move radially through the lead screw 124. The yarn spool shaft 131 installed on the slider 125 moves accordingly. The revolving radius of the twisting groove wheel 135 on the yarn spool shaft 131 and the yarn carrier disk 132 fixed thereon are also adjusted synchronously and precisely.

[0031] The parts not covered in this utility model are the same as or can be implemented using existing technologies.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
