Description

Technical Field

[0001] This utility model belongs to the field of spinning-related technology, and in particular relates to a special tool for disassembling the reaction chamber of a spinning machine. Background Technology

[0002] Continuously spun viscose filament is a high-performance fiber. In recent years, with breakthroughs in spinning technology and increased market demand, its production capacity and product quality have been significantly improved. Traditional continuous spinning machines have a spinning speed of 142 m / min, but with technological upgrades, the spinning speed of viscose filament spinning machines can now be increased to 180 m / min or even higher. When the filament's travel speed in the acid bath increases, to meet the process forming parameters required for viscose cellulose filament, the acid bath flow rate must be increased to match the high spinning speed of the filament, in order to achieve the ideal quality requirements of the spun product. The filament is processed in the acid bath reaction chamber, but the following drawbacks still exist in the cleaning process after the reaction chamber is used:

[0003] Currently, in the continuous filament spinning process, residues easily accumulate in the inlet of the spinning machine's reaction chamber, affecting production efficiency and product quality. The inlet is located inside the inlet tube and is blocked by rubber plugs. Because the inlet inside the inlet tube is an embedded design, the inlet is quite deep inside the tube, making it difficult to manually remove or install the rubber plugs. Therefore, the disassembly and cleaning of the inlet on the spinning machine's reaction chamber is quite difficult and requires special tools to assist in removing the rubber plugs inside the inlet.

[0004] Because the rubber stopper and drainage port are located deep inside, it is impossible to directly reach in to disassemble and install them. Tools are required for assistance. However, when using tools to assist in disassembly and installation, it is difficult to ensure stable clamping of the rubber stopper. If the force position is not stable enough, it is easy for the rubber stopper and drainage port to be difficult to align. Utility Model Content

[0005] The purpose of this utility model is to provide a special tool for disassembling the reaction chamber of a spinning machine. By setting up a sleeve, control lever, handle, slot, groove, pressure plate, and rubber pad, it solves the problems of high difficulty in disassembling and cleaning the inlet of the reaction chamber of the spinning machine, and insufficient stability of the connection between the tool and the rubber plug when disassembling and installing the rubber plug inside the inlet.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a special tool for disassembling the reaction chamber of a spinning machine, including a sleeve, a pressure plate and a calibration plate. Two symmetrically arranged arc plates are fixed to the upper end of the sleeve, and a strip plate is fixed to the upper end of the two arc plates. A control rod is fixed at the center of the top surface of the strip plate, and a handle is fixed to the top of the control rod. The calibration plate is movably sleeved on the outer periphery of the control rod.

[0008] The lower part of the sleeve is symmetrically provided with slots, and each slot is provided with a groove on the side of the sleeve above it, and the two sides of the groove are covered with a rubber sleeve.

[0009] Furthermore, the bottom of the slot is rounded, and the width of the slot is three times that of the slot.

[0010] Furthermore, a pressure plate is also provided inside the sleeve. A rubber pad is fixed to the bottom surface of the pressure plate, and a screw is rotatably connected to the center of the top surface of the pressure plate. The diameter of the pressure plate is smaller than the inner diameter of the sleeve.

[0011] Furthermore, two symmetrically distributed arc plates are fixed to the upper end of the sleeve, and a strip plate is fixed between the opposite faces of the top of the two arc plates. The upper part of the screw threaded upward through the strip plate and a handwheel is fixed thereon.

[0012] Furthermore, the height of the first arc plate is lower than the height of the second arc plate, and the handwheel is located between the first and second strip plates. The first and second strip plates are arranged in a crisscross pattern when viewed from above.

[0013] Furthermore, the bottom surface of the calibration plate is provided with an annular groove, the diameter of the calibration plate is smaller than the length of the handle, and the diameter of the calibration plate is larger than the diameter of the sleeve.

[0014] This utility model has the following beneficial effects:

[0015] This invention solves the problem of difficult disassembly and cleaning of the drainage port on the reaction chamber of a spinning machine by setting up a sleeve, control lever, handle, slot, and groove. When removing the rubber plug inside the drainage port, the sleeve is inserted into the ear plate of the rubber plug through the groove at its bottom, so that the ear plate on the rubber plug enters the slot. At this time, the upper part of the rubber plug enters the sleeve, and the ear plate is in the slot. Slightly rotate the sleeve so that the ear plate contacts the side wall of the slot. Then, rotate the control lever by the handle. The control lever, together with the second strip plate and the second arc plate, rotates, which in turn rotates the sleeve, causing the rubber plug to rotate and be removed. The whole process does not require manual insertion into the drainage tube, which solves the problem of inconvenient disassembly of the rubber plug inside the drainage port in a confined space and facilitates subsequent cleaning operations.

[0016] This invention solves the problem of insufficient stability in the connection between the tool and the rubber plug when disassembling and installing the plug inside the drainage port by setting a pressure plate and a rubber pad. Before installing the plug, insert the upper part of the plug into the sleeve and rotate the sleeve slightly so that the ear plate contacts the side wall of the slot. Then, rotate the handwheel to lower the screw and pressure plate until the plug is pressed tightly and cannot move. At this time, the connection between the tool and the plug is relatively stable and will not easily shake, which makes it easier to align the plug with the drainage port for screwing and installation. Secondly, because the handwheel is positioned high, close to the upper end of the drainage tube, during disassembly, you only need to insert your finger to turn the handwheel to release the pressure plate and remove the plug.

[0017] This invention uses a calibration plate to ensure that the threads on the rubber plug are accurately aligned with the threads inside the drainage port when installing the plug, thus guaranteeing precise installation positioning. The annular groove at the bottom of the calibration plate is fitted over the upper end of the drainage tube. At this time, the control lever and the center of the sleeve holding the rubber plug are on the same center line, so the external threads on the rubber plug can be accurately aligned with the internal threads inside the drainage port, enabling a quick and accurate connection.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Please see Figure 1-10 As shown, this utility model is a special tool for disassembling the reaction chamber of a spinning machine, including a sleeve cylinder 1, a pressure plate 2, and a calibration plate 3;

[0033] First, this special tool is used to disassemble and assemble the rubber plug in the drainage port of the drainage tube on the reaction chamber of the spinning machine. The drainage port in the drainage tube is an embedded design, and the drainage port is relatively deep inside the drainage tube. The drainage port is provided with internal threads (the structure of the drainage tube and the drainage port is as follows). Figure 5 , 6 As shown), it connects to the threaded post at the bottom of the rubber stopper. The upper part of the rubber stopper is a cylindrical structure with two lugs on its circumference for screwing. The diameter of the upper part of the rubber stopper is larger than its lower diameter (e.g., Figure 9 (as shown)

[0034] Two symmetrically arranged arc plates 102 are fixed at the upper end of the sleeve 1, and a strip plate 1021 is fixed at the upper end of the two arc plates 102. A control lever 104 is fixed at the center of the top surface of the strip plate 1021. A handle 105 is fixed at the top of the control lever 104, and a calibration plate 3 is movably sleeved on the outer periphery of the control lever 104.

[0035] The sleeve 1, as the main auxiliary component, is fitted over the rubber plug that needs to be removed and installed on the drainage port. The upper part of the sleeve 1 is equipped with a strip plate 1021 via an arc plate 102, and a control lever 104 is installed on the strip plate 1021. The top of the control lever 104 extends out of the drainage tube and is equipped with a handle 105. Therefore, it is not necessary to put your hand into the drainage tube for removal and installation. The sleeve 1 can be rotated by operating the control lever 104 through the handle 105 outside the drainage tube, and the rubber plug will be rotated for removal and installation.

[0036] The lower part of the sleeve 1 is symmetrically provided with slots 103, and each slot 103 is provided with a slot 106 on the side of the sleeve 1 above the sleeve 1, and the two sides of the slot 106 are covered with rubber sleeves 107.

[0037] The slot 103 is designed to allow the ear plate on the rubber plug to pass through, so that the ear plate enters the slot 106 and the upper part of the rubber plug enters the sleeve 1. With the design of the rubber sleeve 107, when the ear plate is in close contact with the edge of the slot 106, it will not be worn by the ear plate under external force rotation.

[0038] The bottom of slot 103 is rounded, and the width of slot 106 is three times that of slot 103; this provides sufficient space for the ear plate to limit movement and prevent displacement.

[0039] The sleeve 1 is also equipped with a pressure plate 2. A rubber pad 203 is fixed on the bottom surface of the pressure plate 2, and a screw 201 is rotatably connected at the center of the top surface of the pressure plate 2. The diameter of the pressure plate 2 is smaller than the inner diameter of the sleeve 1.

[0040] When the rotating screw 201 presses the pressure plate 2 against the upper part of the rubber stopper, the rubber pad 203 contacts the top surface of the rubber stopper, preventing wear on the rubber stopper and increasing friction during subsequent force application.

[0041] The upper end of the sleeve 1 is also fixed with two symmetrically distributed arc plates 101, and a strip plate 1011 is fixed between the opposite faces of the top of the two arc plates 101. The upper part of the screw 201 is threaded upward through the strip plate 1011 and a handwheel 202 is fixed thereon.

[0042] By using two arc plates 101 to install a strip plate 1011, the screw 201 passes through. When the handwheel 202 is rotated, the screw 201 moves up and down within the strip plate 1011, thereby controlling the lifting and lowering of the pressure plate 2.

[0043] The height of the first arc plate 101 is lower than the height of the second arc plate 102, and the handwheel 202 is located between the first strip plate 1011 and the second strip plate 1021. The first strip plate 1011 and the second strip plate 1021 are arranged in a crisscross pattern when viewed from above.

[0044] The rotation of the screw 201 does not affect the overall rotation of the tool.

[0045] The bottom surface of the calibration plate 3 is provided with an annular groove 301. The diameter of the calibration plate 3 is smaller than the length of the handle 105, and the diameter of the calibration plate 3 is larger than the diameter of the sleeve 1. The thickness of the annular groove 301 is equal to the thickness of the upper end of the drainage tube, and the size of the annular groove 301 matches the size of the upper end of the drainage tube, so that the control lever 104 and the sleeve 1 are centered.

[0046] The specific working principle of this utility model is as follows: the drainage port inside the drainage tube is an embedded design, the drainage port is deep inside the drainage tube, and a rubber plug is installed inside the drainage port for sealing. The upper part of the rubber plug is a cylindrical structure with two ear plates on its periphery, and the lower part of the rubber plug is a threaded post that is screwed into the drainage port for sealing.

[0047] When installing the rubber stopper, first insert the sleeve 1 through the slot 103 at its bottom into the ear plate of the rubber stopper, so that the ear plate on the rubber stopper enters the slot 106. At this time, the upper part of the rubber stopper enters the sleeve 1, and the ear plate is in the slot 106. Slightly rotate the sleeve 1 so that the ear plate contacts the rubber sleeve 107 on the side wall of the slot 106. Then, rotate the handwheel 202 to lower the screw 201 and the pressure plate 2 until the pressure plate 2 and the rubber pad 203 at its bottom press the rubber stopper so that it cannot move. At this time, the connection between the tool and the rubber stopper is relatively stable and will not easily shake. Then, insert the sleeve 1 along with the rubber stopper into the drainage tube, and then cover the drainage tube with the calibration plate 3. At the top, the annular groove 301 at the bottom of the calibration plate 3 is fitted onto the upper port of the drainage tube. At this time, the center of the control lever 104 and the sleeve 1 holding the rubber plug are on the same center line, so that the external thread on the rubber plug is precisely aligned with the internal thread in the drainage port. Then, by rotating the control lever 104 through the handle 105, the control lever 104 rotates along with the strip plate 1021 and the arc plate 102, which in turn rotates the sleeve 1, causing the rubber plug to rotate into the drainage port and complete the installation. Afterwards, because the handwheel 202 is positioned high and close to the upper port of the drainage tube, when removing the tool, you only need to insert your finger into the handwheel 202 to release the rubber plug from the pressure plate 2, and then you can remove the tool.

[0048] When removing the rubber stopper, follow the above operating direction. The difference is that there is no need for the positioning of the calibration plate 3, nor is there a need for the pressure plate 2 to press the rubber stopper. Simply put the sleeve 1 over the rubber stopper and rotate to remove it.

[0049] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
