Description

Technical Field

[0001] This utility model relates to a spinneret top rod, specifically a punching top rod with a pressure sensor. Background Technology

[0002] The spinneret is a crucial component in spinning equipment within the field of spinning technology. Its function is to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores, which are then solidified by a solidification medium such as air or a solidification bath to form filaments. A key piece of equipment used to manufacture the micropores of the spinneret is the punching machine, which can be manual or automatic. The ejector pin is a vital component on the punching machine used to transmit the punching force to the punch. A typical ejector pin is merely an actuator used to transmit force and stroke, ensuring that the force and stroke are executed according to the output of the power source. In actual production, due to the anisotropy of spinneret materials, increasingly smaller orifices, and higher consistency in length-to-diameter ratios, the higher the dimensional accuracy of the spinneret's spinneret surface within its thickness, the higher the manufacturing cost. Ordinary ejector pins, combined with existing equipment, cannot meet the current requirements for micropore dimensional accuracy and the high dimensional accuracy of the spinneret blanks within its thickness, resulting in high production costs and low orifice precision. Therefore, a new type of pressure-sensing punching ejector pin is needed to solve these problems. Utility Model Content

[0003] The technical problem this invention aims to solve is: how to make the numerous holes on the spinneret as uniform in size as possible, maintain a highly consistent length-to-diameter ratio, and ensure that the size and quality of the extruded filaments are highly consistent.

[0004] To address the aforementioned problems, the technical solution proposed by this utility model is: a punching top rod with a pressure sensor, comprising a punch rod, a pressure sensor, and a top block, wherein one end of the pressure sensor is connected to the punch rod, and the other end of the pressure sensor is connected to the top block; a data line is provided on the pressure sensor, and the other end of the data line is connected to the equipment control system.

[0005] Preferably, the rear end of the pressure sensor is provided with a rear connecting rod, and the rear end of the rear connecting rod is connected to the front end of the punch.

[0006] Preferably, the rear end of the rear connecting rod is provided with an external thread, and the front end of the punch has an internal thread hole that matches the external thread of the rear connecting rod. The rear end of the rear connecting rod and the front end of the punch are connected by a threaded engagement.

[0007] Preferably, the front end of the pressure sensor is provided with a front connecting rod, and the front end of the front connecting rod is connected to the rear end of the top block.

[0008] Preferably, the front end of the front connecting rod is provided with an external thread, and the rear end of the top block is provided with an internal thread hole that matches the external thread of the front connecting rod. The front end of the front connecting rod and the rear end of the top block are connected by a threaded engagement.

[0009] Preferably, nuts are installed on both the front and rear connecting rods. Tightening the nuts on the front and rear connecting rods causes the nuts to abut against the front end of the punch and the rear end of the top block, respectively.

[0010] The beneficial technical effects of this utility model are:

[0011] By installing a pressure sensor in front of the push rod and a top block in front of the pressure sensor, the working pressure value of the punch can be detected when the punch pushes the punch to punch the spinneret. At the same time, the measured data is fed back to the equipment control system. Based on the feedback value, the force and displacement of the power source on the push rod are adjusted, so that the punching depth is controlled and punches of consistent size can be produced, thereby ensuring that the size and quality of the filaments produced are highly consistent.

[0013] In the diagram: 1. Punch rod; 2. Pressure sensor; 3. Top block; 4. Rear link; 5. Front link; 6. Data cable. Detailed Implementation

[0014] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1

[0015] like Figure 1 As shown, the push rod in this embodiment includes a punch rod 1, a pressure sensor 2, and a push block 3. A front connecting rod 5 is provided at the front end of the pressure sensor 2, and a rear connecting rod 4 is provided at the rear end of the pressure sensor 2. The front end of the front connecting rod 5 has an external thread, and the rear end of the push block 3 has an internal threaded hole that matches the external thread of the front connecting rod 5. The front end of the front connecting rod 5 and the rear end of the push block 3 are connected by a threaded engagement. The rear end of the rear connecting rod 4 has an external thread, and the front end of the punch rod 1 has an internal threaded hole that matches the external thread of the rear connecting rod 4. The rear end of the rear connecting rod 4 and the front end of the punch rod 1 are connected by a threaded engagement.

[0016] To prevent the connection between pressure sensor 2 and punch rod 1 and top block 3 from loosening during operation, nuts are installed on the threads of the front end of the front connecting rod 5 and the rear end of the rear connecting rod 4. After pressure sensor 2 and top block 3 are installed on punch rod 1 in sequence, the nuts on the front connecting rod 5 and the rear connecting rod 4 are tightened so that the nuts abut against the front end of punch rod 1 and the rear end of top block 3, thereby securing punch rod 1, pressure sensor 2 and top block 3 together.

[0017] In this embodiment, both the punch rod 1 and the top block 3 are prismatic, while the front connecting rod 5 and the rear connecting rod 4 are cylindrical. After the top rod is installed, the punch rod 1, the top block 3, the front connecting rod 5, and the rear connecting rod 4 are coaxial. A data cable 6 is also provided on the pressure sensor 2, with the other end of the data cable 6 connected to the equipment control system. During actual operation, a power source, which can be a hydraulic cylinder, is located behind the punch rod 1, and a punch is located in front of the top block 3. The power source sequentially drives the punch rod 1, the pressure sensor 2, the top block 3, and the punch to strike the spinneret, punching holes in the spinneret.

[0018] During punching, pressure sensor 2 can dynamically measure the load working pressure value of the punch in real time and feed the measured data back to the equipment control system. Based on the feedback value, the power source adjusts the force and displacement of the push rod, so that the punching depth is controlled and punches of consistent size can be produced, thereby ensuring that the size and quality of the ejected wire are highly consistent.

[0019] Obviously, any improvements or modifications made without departing from the principles described in this utility model should be considered within the scope of protection of this utility model.
