Description

Technical Field

[0001] This utility model relates to the field of fiber tow technology, and in particular to a water bath drawing groove device for chemical fiber equipment. Background Technology

[0002] The water bath drawing tank is one of the important pieces of equipment in the post-processing unit, and it is generally located between the first drawing machine and the second drawing machine. The main drawing of the filament bundle takes place in the tank. It is a device that heats the undrawn filament bundle to the glass transition temperature in the water bath drawing tank for drawing.

[0003] Currently, after the water flows into the spray pipe through the water pump, it flows through the slot below the spray pipe into the spray tank below, and then sprays onto the filament bundle through the overflow port of the spray tank.

[0004] The above-mentioned existing technical solutions have the following defects: due to the attenuation of water pressure along the spray pipe, the water flow entering the spray pipe is large at the near end and small at the far end, resulting in uneven application of oil to the fiber bundle and inconsistent fiber stretching. Utility Model Content

[0005] The purpose of this invention is to provide a water bath drawing tank device for chemical fiber equipment, so as to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A water bath drawing tank device for chemical fiber equipment includes a tank body and a tank cover hinged to the top of the tank body. The tank body has a completely open top, with a feed inlet on the right top and a discharge outlet on the left top. The tank cover has a completely open bottom. The tank cover contains a spray pipe and a spray trough. The front and rear ends of the spray pipe are bolted to the inner wall of the tank cover via a first flange and a second flange, respectively. The first flange is a solid flange, and the second flange is a hollow flange. The rear end of the spray pipe passes through the tank cover and is connected to one end of a water pipe, the other end of which is connected to a water pump. The bottom end of the spray pipe has a vertically extending spray nozzle along its length. An adjusting rod assembly is installed inside the spray pipe. The spray trough is fixedly installed at the bottom end of the spray pipe.

[0008] By adopting the above technical solution, the undrawn filaments enter the device from the inlet at the top of the tank for water bath drawing. The front and rear ends of the spray pipe are connected to the inner wall of the tank cover via the first flange and the second flange, respectively. The rear end of the spray pipe is connected to the water pump via a water pipe. The bottom end of the spray pipe is provided with spray nozzles along its length. With the cooperation of the adjusting rod assembly, the water flow and pressure inside the spray pipe can be effectively adjusted to overcome the problem of water pressure attenuation along the flow path, making the water output from all parts of the spray pipe more uniform. This allows the oil sprayed on the undrawn filaments to be more even, avoiding inconsistent filament drawing due to water pressure difference. Furthermore, the spray tank is fixed at the bottom of the spray pipe, and the water flow it receives ensures that the filaments can fully receive uniform water bath drawing under the tank cover, resulting in consistent filament drawing and improved filament quality.

[0009] In a further embodiment, the adjusting rod assembly includes a round rod, a first adjusting block, a second adjusting block, a third adjusting block, and a fourth adjusting block. The first adjusting block, the second adjusting block, the third adjusting block, and the fourth adjusting block are respectively sleeved on the round rod from front to back at certain intervals. The front end of the round rod is fixedly connected to the flange.

[0010] In a further embodiment, the first adjusting block is a circular plate, and the periphery of the circular plate is provided with a plurality of centrifugal protrusions at equal intervals, and the area of ​​the first adjusting block, the second adjusting block, the third adjusting block and the fourth adjusting block decreases in sequence.

[0011] By adopting the above technical solution, the first, second, third and fourth adjusting blocks of different sizes form a stepped flow resistance in the spray pipe, which offsets the water pressure attenuation along the flow path. The first adjusting block, which is close to the water pump, can weaken the impact of the high pressure zone, and the fourth adjusting block, which is far from the water pump, can compensate for the pressure loss, so that the oil is evenly distributed in the spray tank.

[0012] In a further embodiment, the left side wall of the spray tank is provided with a leftward semi-circular flange, and the spray nozzle of the spray pipe is moved down to below the semi-circular flange.

[0013] By adopting the above technical solution, the height of the spray nozzle below the spray pipe is lower than the height of the highest semi-circular flange of the spray tank, thereby ensuring that the oil is evenly diffused in the spray tank. After the water flows through the semi-circular flange structure on the left side wall of the spray tank, it forms a uniformly diffused water curtain by utilizing the secondary distribution effect of the overflow weir, which in turn covers the stretching path of the chemical fiber bundle, making the oil finally sprayed on the bundle more uniform.

[0014] In a further embodiment, baffles are provided on both the front and rear sides of the spray tank. The baffles are snapped onto the spray pipes, and the top of the baffles fits into the inner top of the tank cover. The width of the baffles in the left-right direction is greater than the width of the spray tank in the left-right direction.

[0015] By adopting the above technical solution, the width of the baffle is greater than that of the spray tank, forming left and right side wings to block the water flow and thus effectively prevent water from splashing out.

[0016] In a further embodiment, a plurality of opening devices are provided at equal intervals from right to left on the rear side of the slot cover. Each opening device includes a base, a cylinder, and a connecting rod. The cylinder includes a movable end and a fixed end. The movable end of the cylinder is located at the top of the cylinder body. The cylinder is rotatably mounted on the top of the base. The movable end of the cylinder is fixedly connected to the rear end of the connecting rod, and the front end of the connecting rod is fixedly connected to the rear side of the slot cover.

[0017] By adopting the above technical solution, when it is necessary to open the tank cover, the tank cover is lifted by controlling the extension end of the cylinder to move downward and the connecting rod to move clockwise around the top of the cylinder. Similarly, the tank cover and the object are closed by controlling the extension end of the cylinder to move upward and the connecting rod to move counterclockwise around the top of the cylinder.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By setting up first, second, third, and fourth adjusting blocks of different sizes, a stepped flow resistance can be formed within the spray pipe to offset the attenuation of water pressure along the flow path. The first adjusting block, closer to the water pump, can weaken the impact of the high-pressure zone, while the fourth adjusting block, farther from the water pump, compensates for pressure loss, thus achieving the effect of uniformly distributing the oil agent within the spray tank. Furthermore, the height of the spray nozzle below the spray pipe is lower than the height of the highest semi-circular flange of the spray tank, thereby ensuring uniform diffusion of the oil agent within the spray tank. After the water flow is guided by the semi-circular flange structure on the left side wall of the spray tank, a uniformly diffused water curtain is formed by the secondary distribution effect of the overflow weir, which then covers the stretching path of the chemical fiber bundle, making the oil agent finally sprayed onto the bundle more evenly.

[0027] Example 1:

[0028] like Figures 1-4 As shown, a water bath drawing tank device for chemical fiber equipment includes a tank body 2 and a tank cover 1 hinged to the top of the tank body 2. The tank body 2 has a completely open top structure. A feed inlet is provided at the top right side of the tank body 2, and a discharge outlet is provided at the top left side of the tank body 2. The tank cover 1 has a completely open bottom structure. A spray pipe 3 and a spray tank 5 are provided inside the tank cover 1. The front end and rear end of the spray pipe 3 are bolted to the inner wall of the tank cover 1 through a first flange 8 and a second flange 9, respectively. The first flange 8 is a solid flange, and the second flange 9 is a hollow flange. The rear end of the spray pipe 3 passes through the tank cover 1 and is connected to one end of a water pipe. The other end of the water pipe is connected to a water pump 7. A vertically penetrating spray nozzle is provided at the bottom end of the spray pipe 3 along its length. An adjusting rod connector 4 is provided inside the spray pipe 3. The spray tank 5 is fixedly installed at the bottom end of the spray pipe 3.

[0029] The adjusting rod assembly 4 includes a round rod 41, a first adjusting block 42, a second adjusting block 43, a third adjusting block 44, and a fourth adjusting block 45. The first adjusting block 42, the second adjusting block 43, the third adjusting block 44, and the fourth adjusting block 45 are respectively fitted onto the round rod 41 at certain intervals from front to back. The front end of the round rod 41 is fixedly connected to the flange 8. The first adjusting block 42 is a round plate with multiple centrifugal protrusions evenly spaced along its periphery. The area of ​​the first adjusting block 42, the second adjusting block 43, the third adjusting block 44, and the fourth adjusting block 45 decreases sequentially. The left side wall of the spray tank 5 has a leftward curl. The spray nozzle of the spray pipe 3 is located below the curl; baffles 6 are provided on the front and rear sides of the spray tank 5. The baffles 6 are snapped onto the spray pipe 3. The top of the baffle 6 is attached to the inner top of the tank cover 1. The width of the baffle 6 in the left and right direction is greater than the width of the spray tank 5 in the left and right direction; multiple opening devices are provided at equal intervals from right to left on the rear side of the tank cover. The opening device includes a base, a cylinder and a connecting rod. The cylinder includes a movable end and a fixed end. The movable end of the cylinder is located at the top of the cylinder body. The cylinder is rotatably mounted on the top of the base. The movable end of the cylinder is fixedly connected to the rear end of the connecting rod. The front end of the connecting rod is fixedly connected to the rear side of the tank cover 1.

[0030] Specific implementation process: Undrawn filaments enter the device through the inlet. Then, water pump 7 is started, pumping water through the water pipe into spray pipe 3. Inside spray pipe 3, the adjusting rod assembly 4 functions. A first adjusting block 42, a second adjusting block 43, a third adjusting block 44, and a fourth adjusting block 45 are fitted onto the round rod 41 at certain intervals, with their areas decreasing sequentially. This adjusts the water flow, overcomes the pressure attenuation along the flow path, and ensures more uniform water output from each section of spray pipe 3. Then, water flows from the bottom of spray pipe 3 along its length... The oil flows out through the spray nozzle. Because the left side wall of the spray tank 5 is turned to the left semi-circular edge and the spray nozzle is moved down to the bottom of the curl, and the baffles 6 on the front and rear sides of the spray tank 5 are engaged with the spray pipe 3, the top of the baffle 6 is attached to the top of the inside of the tank cover 1, and the width is greater than the width of the spray tank 5, which can effectively prevent water from splashing out. Finally, the oil is evenly sprayed on the filament bundle, heating the undrawn filament bundle to the glass transition temperature for drawing, ensuring that the filament bundle is drawn evenly, improving the quality of the filament bundle, and finally coming out from the filament outlet.
