Description

Technical Field

[0001] The utility model relates to the technical field of two-for-one twisting machines, in particular to a twisting disc disassembly and assembly structure. Background Art

[0002] The two-for-one twister is a twisting device, which is essentially a doubling device, also called a doubling machine. It can achieve two twists in one turn, and the twisting efficiency is several times higher than that of traditional twisting equipment. The twisting disk is an important component structure on the twisting machine spindle.

[0003] For example, Chinese patent CN218910635U discloses a twisting disc that is easy to assemble, including a spindle rod, a twisting disc body and a connecting mechanism, wherein the outer side of the spindle rod is fixedly connected to the twisting disc body by a connecting mechanism.

[0004] The above-mentioned twisting disk which is easy to assemble still has certain shortcomings. It squeezes the spring to restore the connecting plate and drives the clamping block to restore, clamps the connecting block, and fixes the twisting disk body, thereby making the installation of the twisting disk more convenient and quick, saving installation time. At the same time, by pulling the sliding rod, the fixation of the connecting block is released, and the twisting disk body can be quickly disassembled. However, since the space under the twisting disk is small, the maintenance personnel need to pull the sliding rod in the narrow space under the twisting disk, and the disassembly method is relatively cumbersome. Therefore, the present application proposes a twisting disk disassembly and assembly structure to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a twisting disk disassembly and assembly structure, which has the advantages of easy disassembly and assembly of the twisting disk, and solves the problem that maintenance personnel need to pull the sliding rod in the narrow space below the twisting disk, and the disassembly method is relatively cumbersome.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a twisting disk disassembly and assembly structure, comprising a spindle rod, a tray welded to the outside of the spindle rod, an installation mechanism provided on the outside of the spindle rod, a twisting disk body provided on the upper surface of the tray, and four positioning blocks provided on the bottom of the twisting disk body.

[0007] Furthermore, the mounting mechanism includes a threaded sleeve welded to the outside of the spindle rod, the outer side of the threaded sleeve is threadedly connected to a sleeve, the outer side of the sleeve is welded with a fixing ring, the outer side of the sleeve is horizontally provided with a ring through a bearing, the outer side of the ring is hinged with four hinged rods through a hinge shaft, and four blocks are provided at the bottom of the tray.

[0008] Furthermore, the upper surface of the tray is provided with four positioning grooves extending to the bottom thereof, and the four positioning blocks are respectively fitted with clearances in the four positioning grooves.

[0009] Furthermore, the twisting disc body is in the shape of a disc, and a positioning hole extending to the bottom is provided at the center of the upper surface of the twisting disc body, and the spindle rod is movably fitted in the positioning hole.

[0010] Furthermore, the four hinged rods are hinged to opposite sides of the four clamping blocks through hinge shafts respectively.

[0011] Furthermore, four slides are provided at the bottom of the tray, and the four clamping blocks slide horizontally inside the four slides respectively.

[0012] Furthermore, one side opposite to the other of the four positioning blocks is provided with a clamping groove which is gap-matched with the clamping block.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] When the twisting disc is disassembled and assembled, the fixing ring is held and rotated, causing the sleeve to rotate and move upward. At this time, the sleeve will not rotate with the sleeve because it is rotatably connected to the sleeve through a bearing. At this time, the four hinged rods respectively drive the four clamping blocks to be respectively clamped into the inside of the four clamping grooves, limiting the twisting disc body, thereby facilitating the installation and disassembly of the twisting disc body.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 2A twisting disk disassembly and assembly structure in this embodiment includes a spindle rod 1, a tray 3 is welded to the outside of the spindle rod 1, a mounting mechanism 2 is provided on the outside of the spindle rod 1, a twisting disk body 4 is provided on the upper surface of the tray 3, and four positioning blocks 5 are provided at the bottom of the twisting disk body 4.

[0021] The upper surface of the tray 3 is provided with four positioning grooves 6 extending to its bottom, and the four positioning blocks 5 are respectively fitted with the four positioning grooves 6. The twisting disk body 4 is in the shape of a disc, and a positioning hole extending to its bottom is provided on the upper surface of the twisting disk body 4 and at its center. The spindle rod 1 is movably fitted with the positioning hole, and the twisting disk body 4 is sleeved on the outside of the spindle rod 1 and movably fitted with the upper surface of the tray 3. At the same time, the four positioning blocks 5 are respectively plugged into the four positioning grooves 6.

[0022] See also Figure 3 In this embodiment, the mounting mechanism 2 includes a threaded sleeve 201 welded to the outside of the spindle rod 1, the outer side of the threaded sleeve 201 is threadedly connected to a sleeve 202, the outer side of the sleeve 202 is welded with a fixing ring 203, and the outer side of the sleeve 202 is horizontally provided with a collar 204 through a bearing. Holding the fixing ring 203 and starting to rotate it causes the sleeve 202 to start rotating and move upward. The outer side of the collar 204 is hinged with four hinged rods 205 through a hinge shaft, and four blocks 206 are provided at the bottom of the tray 3.

[0023] The four hinged rods 205 are hinged on the opposite sides of the four blocks 206 through hinge shafts respectively. Four slides are provided at the bottom of the tray 3. The four blocks 206 slide horizontally inside the four slides respectively. The four positioning blocks 5 are provided on the opposite sides with grooves that match the gaps with the blocks 206. Since the ring 204 is connected to the sleeve 202 through a bearing for rotation, it will not rotate with the sleeve 202. At this time, the four hinged rods 205 respectively drive the four blocks 206 to be stuck into the inside of the four grooves, limiting the twisting disk body 4, so as to achieve the purpose of facilitating the installation and disassembly of the twisting disk body 4.

[0024] It can be understood that holding the fixing ring 203 and starting to rotate it causes the sleeve 202 to start rotating and move upward. At this time, the ring 204 is connected to the sleeve 202 through a bearing, so it will not rotate with the sleeve 202. At this time, the four hinged rods 205 respectively drive the four blocks 206 to be respectively stuck into the inside of the four slots, limiting the twisting disk body 4, so as to facilitate the installation and removal of the twisting disk body 4.

[0026] The working principle of the above embodiment is:

[0027] When it is necessary to use the twisting disk assembly and disassembly structure, the personnel in this technical field will sleeve the twisting disk body 4 on the outside of the spindle rod 1 and movably fit it with the upper surface of the tray 3 during assembly. At the same time, the four positioning blocks 5 are respectively plugged into the four positioning grooves 6. Then, the fixing ring 203 is held and started to rotate, so that the sleeve 202 starts to rotate and move upward. At this time, the ring 204 will not rotate with the sleeve 202 because it is connected to the sleeve 202 through a bearing. At this time, the four hinged rods 205 respectively drive the four clamping blocks 206 to be respectively clamped into the inside of the four clamping grooves, limiting the twisting disk body 4, so as to achieve the purpose of facilitating the installation and disassembly of the twisting disk body 4.
