Description

Technical Field

[0001] The present application relates to the technical field of spinning, and specifically to a jet vortex spinning device. Background Art

[0002] Jet vortex spinning is developed on the basis of jet spinning. It uses the high-speed rotating air flow generated by compressed air in the nozzle to twist the sliver, abandoning the traditional way of twisting by spinning machinery, forming an air flow twisting area with a rotational speed of up to 300,000 revolutions per minute, which is the highest known new spinning technology at present. Jet vortex spun yarn has the advantages of less hairiness, less pilling of the fabric, good dyeing performance and wear resistance, smooth appearance of the fabric, as well as good hygroscopicity and quick drying. Therefore, jet vortex spun yarn has a wide range of application fields and is often used to make knitted sportswear, casual clothing and home textile products, etc. The vortex spinning equipment is more and more widely used.

[0003] At present, the structures of the vortex spinning devices in the market are similar. They all spin by controlling the opening and closing of the upper bracket and the lower bracket through solenoid valves. Among them, the cotton feeding channel for fiber transmission and the upper nozzle for generating vortex are installed on the upper bracket with screws. Due to the up-and-down installation method, there is interference with the position of the roller shaft after assembly. When the spinning machine is working normally, under the condition that each roller shaft rotates at a high speed, it is impossible to maintain the cotton feeding channel and the upper nozzle of the problematic spinning device, which affects the spinning efficiency. Chinese Patent (Publication No.: CN105239223B) discloses a jet vortex spinning device, which divides the upper bracket into two parts, namely a movable upper bracket and a fixed upper bracket, and installs the cotton feeding channel and the upper nozzle on the movable upper bracket. The movable upper bracket can be removed from the fixed upper bracket without any obstacle when the spinning machine is working normally, which is convenient for maintenance.

[0004] However, in the above document, the upper yarn forming assembly is fixed to the inner side of the movable upper bracket by screws, and the movable upper bracket is fixedly installed on the fixed upper bracket by positioning pins and screws. Since the disassembly operation of the movable upper bracket requires completely removing the screws and the positioning pins and placing them, it is easy to cause the loss of the screws and the positioning pins, which is not conducive to the installation of the movable upper bracket after maintenance. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present application provides a jet vortex spinning device, which has the advantages of being easy to disassemble, etc., and solves the problem of inconvenient disassembly.

[0006] To achieve the above object, the present application provides the following technical solution: An air-jet vortex spinning device, comprising a fixed upper bracket, a lower yarn-forming joint and an upper yarn-forming joint. A movable upper bracket is fixed to the right side of the upper yarn-forming joint. Connecting blocks are fixed to both the front and rear end walls of the movable upper bracket.

[0011] Further, positioning holes are opened at the top of the two plugging blocks, and the positioning blocks are located inside the positioning holes and are plugged with them.

[0012] Adopting the above technical solution, the positioning block can be located inside the plugging block.

[0013] Further, sliding grooves are opened on the front and rear walls of the inner cavity of the plug block, and the sliders are located inside the sliding grooves and are slidably connected to them.

[0014] Adopting the above technical solution can limit the range of up and down movement of the positioning block, so that the positioning block can be accurately moved into the plugging block.

[0015] Further, the moving structure includes two pulling blocks, two support rods, two return springs, and moving blocks fixedly installed on the opposite sides of the two pulling blocks. The return springs are sleeved on the outer surfaces of the support rods.

[0016] Adopting the above technical solution can drive the positioning block to move up or down.

[0017] Further, the end of the pressing rod far from the top of the cross plate is hinged to the lower end of the pulling block.

[0018] With the above technical solution, it is convenient to pull the pressure rod from an inclined state to a horizontal state or from a horizontal state to an inclined state.

[0019] Further, the support rod is fixed to the left and right walls of the inner cavity of the insertion block, and a circular hole for the pull block to slide on the outer surface of the support rod is provided on the right side of the pull block.

[0020] With the above technical solution, the pull block can move outside it.

[0021] Further, the moving block is in a T shape, and sliding holes for the moving block to penetrate out of their interiors are provided on the opposite sides of the two insertion blocks.

[0022] With the above technical solution, it is convenient to connect the moving block and the pull block, facilitating operation by the operator.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For this jet vortex spinning device, by providing a connecting block, an insertion block and a positioning component, it is beneficial to improve the convenience of disassembling and installing the movable upper bracket, and it can avoid the phenomenon that the bolts and positioning pins are lost and thus it is not conducive to fixing it to the fixed upper bracket. Moreover, there is no need to use external tools to disassemble and install the movable upper bracket, which can further improve the convenience during disassembly and installation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figures 1 to 2 , in this embodiment, an air-jet vortex spinning device includes a fixed upper bracket 11, a lower yarn-forming joint 13 and an upper yarn-forming joint 14. A movable upper bracket 12 is fixed to the right side of the upper yarn-forming joint 14. Connecting blocks 15 are fixed to both the front and rear end walls of the movable upper bracket 12. Insert blocks 16 are fixed to both the front and rear ends of the fixed upper bracket 11. A positioning component for fixing the two connecting blocks 15 to the left side thereof is provided inside the two insert blocks 16.

[0031] It should be noted separately that the lower yarn-forming joint 13 is fixed to the left side of the fixed upper bracket 11.

[0032] Please refer to Figures 2 to 3 , the positioning component in this embodiment includes two plug-in blocks 161, two positioning blocks 162, a cross plate 163 fixedly installed at the top end of the positioning block 162, sliders 164 fixedly installed at both the front and rear ends of the cross plate 163, a pressure lever 165 fixedly installed at the top end of the cross plate 163 and hinged thereto, and a moving structure fixedly installed at the top ends of the two pressure levers 165 for pulling them to move.

[0033] Among them, through holes are formed on the left sides of the two insert blocks 16. The plug-in blocks 61 are slidably connected to the inner sides of the through holes. The two plug-in blocks 161 are respectively fixed to the right side walls of the two connecting blocks 15, so that the plug-in blocks 161 can move into the insert blocks 16 through the through holes, thereby enabling the connecting blocks 15 to be plugged and connected to the insert blocks 16.

[0034] Moreover, positioning holes are formed at the top ends of the two plug-in blocks 161. The positioning blocks 162 are located inside the positioning holes and are plugged therewith. The positioning blocks 162 are moved into the positioning holes of the plug-in blocks 161 so as to fix the plug-in blocks 161 inside the insert blocks 16.

[0035] In addition, sliding grooves are formed on the front and rear walls of the inner cavity of the insert blocks 16. The sliders 164 are located inside the sliding grooves and are slidably connected thereto, enabling the cross plate 163 to move smoothly inside the insert blocks 16, and the movement range of the cross plate 163 can be limited by the two sliders 164 in the same group.

[0036] Please refer to Figure 3 , the moving structure in this embodiment includes two pull blocks 167, two support rods 168, two return springs 169, and moving blocks 166 fixedly installed on the opposite sides of the two pull blocks 167. The return springs 169 are sleeved on the outer surfaces of the support rods 168.

[0037] Secondly, the end of the pressure lever 165 far from the top end of the cross plate 163 is hinged to the lower end of the pull block 167. When the pressure lever 165 gradually moves to an inclined state, it can push the cross plate 163 to move downward. When the pressure lever 165 gradually moves to a horizontal state, it can pull the cross plate 163 to move upward.

[0038] In addition, the support rod 168 is fixed to the left and right walls inside the insertion block 16. A round hole for the slider 167 to slide on the outer surface of the support rod 168 is formed on the right side of the slider 167, so that the support rod 168 can support the slider 167 and the return spring 169.

[0039] Meanwhile, the moving block 166 is in a T shape. Slide holes for the moving block 166 to penetrate out of the inside are formed on the opposite sides of the two insertion blocks 16, so that the moving block 166 can move into the insertion block 16 through the slide holes, facilitating the connection between the moving block 166 and the slider 167.

[0040] It should be noted that the lower yarn forming assembly 13 and the upper yarn forming assembly 14 are both well-known to the public in the prior art. The control mode of the present embodiment is controlled by a controller. The electrical components appearing in the text are all connected to the controller and the power supply. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the well-known common knowledge in the art. Therefore, the control mode and the circuit connection of the present invention will not be explained in detail.

[0041] The working principle of the above embodiment is as follows:

[0042] During use, when maintenance personnel need to maintain the upper yarn forming assembly 14, they move the two moving blocks 166 to the right, so that the two moving blocks 166 can drive the two sliders 167 to move to the right inside the insertion block 16. While the slider 167 can move on the outer surface of the support rod 168, the slider 167 can squeeze the return spring 169. And while the slider 167 moves to the right, it can pull the pressure rod 165 from an inclined state to a horizontal state, so that the pressure rod 165 can pull the cross plate 163 upward, enabling the cross plate 163 to pull the positioning block 162 upward, and the positioning block 162 can be removed from the positioning hole of the insertion block 161, that is, the movable upper bracket 12 can be separated from the fixed upper bracket 11, so that it can be removed from the movable upper bracket 12 without any obstacles during the normal operation of the spinning machine, facilitating the maintenance of the upper yarn forming assembly 14;

[0043] When installing after maintenance, repeat the above steps to make the positioning block 162 located at the top inside the insertion block 16, so that the connecting block 15 can drive the insertion block 161 to be inserted into the inside of the insertion block 16, and release the moving block 166. The return spring 169 can push the slider 167 to move to the left, so that the slider 167 can push the positioning block 162 to move downward through the pressure rod 165, and the positioning block 162 can move into the positioning hole of the insertion block 161, thereby fixing the movable upper bracket 12 to the fixed upper bracket 11. This can avoid the phenomenon that the bolts and positioning pins are lost and are not conducive to fixing it to the fixed upper bracket 11, and there is no need to use external tools to disassemble and assemble the movable upper bracket 12, which can further improve the convenience during disassembly and assembly.
