Description

Technical Field

[0001] This utility model belongs to the field of monofilament polyester production technology, and specifically relates to a melt pressure measuring device for a spinning box. Background Technology

[0002] In the production process of monofilament polyester, the measurement of melt pressure inside the spinning box is a crucial step. Precise melt pressure control is essential to ensuring the consistency of fiber quality. The melt pressure sensor inside the spinning box determines whether the filter needs to be replaced based on the pressure difference before and after the pre-filter. The post-filter pressure sensor also plays a role in controlling the screw speed and ensuring stable melt pressure.

[0003] Existing melt pressure measuring devices for spinning boxes are installed inside the spinning box by tightening bolts with external tools. The melt pipes on both sides of the tee pipe transport the spinning melt, and the melt pressure sensor on the upper side of the tee pipe detects the pressure of the spinning melt transported between the two melt pipes inside the tee pipe to ensure stable melt pressure. However, in actual use, the height of the transport pipes of different spinning boxes is different, which makes it difficult and unsuitable to customize different pressure measuring devices according to different transport pipes. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a spinning box melt pressure measuring device. By moving the melt tube upward or downward, the height of the central axis of the melt tube is adjusted so that the melt tube can adapt to the conveying pipeline in different spinning boxes, and the pressure of the spinning melt conveyed in the conveying pipeline is measured.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a spinning box melt pressure measuring device, including a mounting base, a guide frame is provided in the middle of the lower surface of the mounting base, a sliding platform is slidably provided on the guide frame, an installation tube is detachably installed in the middle of the sliding platform, a T-shaped seat is provided at the lower end of the installation tube, and melt tubes are provided on both sides of the T-shaped seat. An adjustment mechanism for adjusting the height of the melt tubes is also provided on the mounting base and the sliding platform; multiple U-shaped mounting plates are fixedly provided on the mounting base; each U-shaped mounting plate has symmetrically distributed mounting holes.

[0006] As a further improvement of this utility model, the adjustment mechanism includes a rotating seat 1 disposed on both sides of the sliding table. The mounting seat is provided with symmetrically distributed guide grooves. A drive seat is slidably disposed inside each guide groove. A rotating seat 2 is disposed on the lower surface of each drive seat. A rotating rod is rotatably disposed on the outer side of each rotating seat 2. The end of the rotating rod away from the rotating seat 2 is rotatably connected to the rotating seat 1.

[0007] As a further improvement of this utility model, a bidirectional lead screw is rotatably provided in the middle of the mounting base, and each drive seat is provided with a threaded groove, which is threadedly connected to the bidirectional lead screw; a knob is fixedly provided at the end of the bidirectional lead screw.

[0008] As a further improvement of this utility model, a melt pressure sensor is provided between the mounting tube and the tee seat, and the melt pressure sensor is installed in conjunction with the central axis of the two melt tubes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, rotating the knob causes the connected bidirectional lead screw to rotate, which in turn causes the sliding table to move the mounting tube up or down. This, in turn, causes the mounting tube to move the melt tube up or down via the tee, thus adjusting the height of the melt tube's central axis.

[0011] Secondly, when the conveying pipeline inside the spinning box that the melt tube needs to adapt to is high, the operator turns the knob to drive the bidirectional lead screw connected to it to rotate, so that the rotating seats on both sides pull the sliding table on the guide frame to slide upward through the rotating rod, so that the installation tube drives the melt tube to move upward through the tee seat.

[0012] Thirdly, when the conveying pipeline in the spinning box that the melt tube needs to adapt to is low, the thread relationship between the bidirectional screw and the drive seat drives the drive seats on both sides to move closer together, so that the rotating seats on both sides push the sliding table to slide down on the guide frame through the rotating rod, so that the installation tube drives the melt tube to move down through the tee seat.

[0013] Fourth, it allows the melt tube to adapt to different conveying pipelines inside the spinning box, and to measure the pressure of the spinning melt conveyed in the conveying pipeline. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a mounting base 101, a guide frame 102 is provided in the middle of the lower surface of the mounting base 101, a sliding table 103 is slidably provided on the guide frame 102, an installation tube 104 is detachably installed in the middle of the sliding table 103, a tee seat 105 is provided at the lower end of the installation tube 104, and melt tubes 106 are provided on both sides of the tee seat 105. The mounting base 101 and the sliding table 103 are also provided with adjustment mechanisms for adjusting the height of the melt tubes 106.

[0022] like Figure 2 , 3 As shown, the adjustment mechanism includes a first rotating seat 201 disposed on both sides of the sliding table 103. The mounting seat 101 has symmetrically distributed guide grooves 202. A drive seat 203 is slidably disposed inside each guide groove 202. A second rotating seat 204 is disposed on the lower surface of each drive seat 203. A rotating rod 205 is rotatably disposed on the outer side of each second rotating seat 204. The end of the rotating rod 205 away from the second rotating seat 204 is rotatably connected to the first rotating seat 201. A bidirectional lead screw 206 is rotatably disposed in the middle of the mounting seat 101. A threaded groove is disposed on each drive seat 203. The threaded groove is threadedly connected to the bidirectional lead screw 206. A knob 207 is fixedly disposed at the end of the bidirectional lead screw 206.

[0023] like Figure 2 , 4 As shown, a melt pressure sensor 107 is provided between the mounting pipe 104 and the tee seat 105. The melt pressure sensor 107 is installed in conjunction with the central axis of the two melt pipes 106.

[0024] like Figure 1 , 2As shown, multiple U-shaped mounting plates 301 are fixedly mounted on the mounting base 101; each U-shaped mounting plate 301 has symmetrically distributed mounting holes 302. (The melt pressure sensor 107 is an ACK-RT-04 type melt pressure sensor with a range of 0–2MPa to 0–150MPa.)

[0025] In use, the U-shaped mounting plate 301 is fixed to a suitable position on the spinning box by tightening the bolts inserted into the mounting hole 302 using external tools.

[0026] Then, the operator rotates knob 207, causing knob 207 to drive the bidirectional lead screw 206 connected to it to rotate. Through the threaded relationship between the bidirectional lead screw 206 and the drive seat 203, the drive seats 203 on both sides move towards each other or away from each other. During the movement of the drive seats 203, the rotating seat 204 rotates with the rotating rod 205, and the rotating rod 205 rotates with the rotating seat 201. This causes the drive seat 203 to drive the sliding table 103 where the rotating seat 201 is located to slide on the guide frame 102 through the rotating rod. This causes the sliding table 103 to drive the mounting tube 104 to move up or down. This causes the mounting tube 104 to drive the melt tube 106 to move up or down through the tee seat 105, thereby adjusting the height of the central axis of the melt tube 106.

[0027] When the conveying pipeline inside the spinning box that the melt tube 106 needs to adapt to is high, the operator turns the knob 207 to drive the bidirectional lead screw 206 connected to it to rotate. This, in turn, through the threaded relationship between the bidirectional lead screw 206 and the drive seat 203, causes the drive seats 203 on both sides to move in opposite directions. At this time, the rotating seat 204 rotates with the rotating rod 205, and the rotating rod 205 rotates with the rotating seat 201. The rotating rod 205 acts as a pull rod, causing the rotating seats 204 on both sides to pull the sliding table 103 upwards on the guide frame 102 via the rotating rod 205. This causes the mounting tube 104 to drive the melt tube 106 upwards through the tee seat 105. When the melt tube 106... 6. When the conveying pipeline inside the spinning box needs to be lower, the threaded relationship between the bidirectional screw 206 and the drive seat 203 drives the drive seats 203 on both sides to move closer together. At this time, the rotating seat 204 rotates with the rotating rod 205, and the rotating rod 205 rotates with the rotating seat 201. The rotating rod 205 is equivalent to a push rod, so that the rotating seats 204 on both sides push the sliding table 103 to slide downward on the guide frame 102 through the rotating rod 205, so that the mounting tube 104 drives the melt tube 106 to move downward through the three-way seat 105. In this way, the melt tube 106 can adapt to the conveying pipeline inside different spinning boxes and the pressure of the spinning melt conveyed in the conveying pipeline can be measured.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
