Description

Technical Field

[0001] This invention relates to the field of texturing machine technology, and more specifically, to a pneumatic automatic tube rack device for a texturing machine. Background Technology

[0002] Texturing machines are the core equipment in the chemical fiber textile industry for processing POY (pre-oriented yarn) into DTY (drawn textured yarn). The bobbin holder, as a key auxiliary component for bearing, positioning, and changing full / empty bobbins, directly affects the production efficiency and product quality of the texturing machine.

[0003] Traditional texturing machines mostly use tool-type bobbin holders, which have the following core pain points: they rely on manual or semi-mechanized operation, the bobbin clamping and replacement process is cumbersome, and the replacement of a single bobbin is time-consuming, which cannot match the high-speed continuous production rhythm of the texturing machine; at the same time, the manual labor intensity is high, and human error can easily lead to bobbin positioning deviation, causing production problems such as wire breakage and poor winding. Therefore, those skilled in the art have provided a pneumatic automatic bobbin holder device for texturing machines to solve the above-mentioned problems. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a pneumatic automatic tube rack device for a texturing machine. This device solves the problems of long tube changing time, high labor intensity, and easy positioning deviation caused by the reliance on manual or semi-mechanized operation of traditional texturing machine tube racks. It has the advantages of automatic synchronous opening and closing of the clamping arm through pneumatic drive and synchronous linkage mechanism, which shortens tube changing time, improves production efficiency, ensures safety, and has low maintenance cost and is easy to upgrade and modify.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A pneumatic automatic tube rack device for a texturing machine includes a frame body, on which a cylinder body is mounted. A solenoid valve is adapted to the cylinder body. Clamping arms are hinged to both the left and right sides of the frame body. Clamping wheels are mounted on opposite sides of the two clamping arms. A synchronous connecting rod is connected to the piston rod of the cylinder body. The synchronous connecting rod is connected to the two clamping arms. The cylinder body drives the two clamping arms to open and close through the movement of the piston rod and the synchronous connecting rod.

[0007] Two spring-loaded feet are installed at the bottom of the frame body. The top of the spring-loaded feet extends through and to the top of the clamping arm. The spring-loaded feet are elastic and can achieve flexible buffering and adaptive tension when clamping the tube.

[0008] A brake pad is hinged inside the clamping arm, and a spring is installed on the frame body. The end of the spring away from the frame body is connected to the brake pad. When the clamping arm opens, the spring pulls the brake pad to rotate, causing the brake pad to contact and brake the clamping wheel.

[0009] As a further description of the above technical solution: the main body of the frame is formed by high-strength die-cast aluminum alloy bolt connection as the load-bearing foundation, and the main body of the frame is provided with uniformly distributed installation interfaces for direct connection with the texturing machine station.

[0010] As a further description of the above technical solution: a hinge seat is installed on the frame body, and the cylinder body is installed on the top of the hinge seat.

[0011] As a further description of the above technical solution: a rack arm is installed on the clamping arm, and the rack arm is located at the bottom of the clamping wheel.

[0012] As a further description of the above technical solution: the clamping arm is provided with an installation through groove, and the clamping wheel is installed inside the installation through groove by bolts.

[0013] As a further description of the above technical solution: the solenoid valve is connected to the PLC controller of the texturing machine, and the PLC controller of the texturing machine can realize remote control.

[0014] Compared with the prior art, the advantages of this invention are:

[0015] This invention achieves automatic and synchronous opening and closing of the clamping arm through pneumatic drive and synchronous linkage mechanism, which can quickly complete the automatic clamping and replacement of tubes, significantly shortening the tube changing operation time and accurately matching the high-speed continuous production rhythm of the texturing machine, thereby effectively improving equipment utilization and overall production efficiency. At the same time, this automated operation mode replaces the traditional manual disassembly or tooling docking, significantly reducing the labor intensity of operators, reducing errors that may be caused by repetitive labor and human intervention, and improving the safety of the operation process.

[0016] In terms of structural design, the core of the device adopts mature and reliable pneumatic components and a simple mechanical linkage mechanism. The overall structure is compact and the manufacturing cost is low. The pneumatic system is easy to maintain and the vulnerable parts are easy to replace, which ensures the long-term stable operation of the equipment and low maintenance costs. In addition, the device frame has a specially reserved standardized installation interface with the original workstation of the texturing machine, which makes the upgrade and transformation process of the equipment simple and quick. No adjustment is required to the main structure of the texturing machine, which greatly reduces the difficulty and cycle of production line technical transformation and realizes efficient and low-cost production automation upgrade.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please see Figures 1-3 In this invention, a pneumatic automatic tube rack device for a texturing machine includes a frame body 1, a cylinder body 2 mounted on the frame body 1, an electromagnetic valve 3 adapted to the cylinder body 2, the electromagnetic valve 3 being connected to the texturing machine PLC controller, which enables remote control; clamping arms 4 are hinged to both sides of the frame body 1, and clamping wheels 5 are mounted on opposite sides of the two clamping arms 4; a synchronous connecting rod 6 is connected to the piston rod of the cylinder body 2, and the synchronous connecting rod 6 is connected to the two clamping arms 4; the cylinder body 2 drives the two clamping arms 4 to open and close through the movement of the piston rod and the synchronous connecting rod 6; a brake pad 8 is hinged inside the clamping arm 4; a spring 9 is mounted on the frame body 1, and the end of the spring 9 away from the frame body 1 is connected to the brake pad 8; when the clamping arm 4 opens, the spring 9 pulls the brake pad 8 to rotate, causing the brake pad 8 to contact and brake the clamping wheel 5.

[0024] Two spring-loaded feet 7 are installed at the bottom of the frame body 1. The top of the spring-loaded feet 7 extends through and to the top of the clamping arm 4. The spring-loaded feet 7 are elastic and can achieve flexible buffering and adaptive tension when clamping the tube. The frame body 1 is formed by high-strength die-cast aluminum alloy bolt connection as the load-bearing foundation. The frame body 1 has evenly distributed installation interfaces 101 for direct connection with the texturing machine station. The frame body 1 is equipped with a hinge seat 10, and the cylinder body 2 is installed on the top of the hinge seat 10.

[0025] In use, the entire device is stably supported by the frame body 1 made of high-strength die-cast aluminum alloy, and is reliably connected to the texturing machine station through the mounting interface 101. When the texturing machine needs to replace or load the tube, the operator sends a command remotely or locally through the texturing machine PLC controller to control the solenoid valve 3 to move, thereby driving the piston rod of the cylinder body 2 to extend or retract. The movement of the piston rod is transmitted to the two hinged clamping arms 4 through the synchronous connecting rod 6, forcing the two clamping arms 4 to move synchronously opening or closing around the hinge point with the frame body 1.

[0026] During the process of clamping arm 4 closing to clamp the tube, the spring-loaded foot 7 installed on the top of clamping arm 4 will first undergo a certain degree of bending deformation due to its elasticity. This deformation generates an elastic force opposite to the direction of cylinder closing. In the normal clamping state, that is, when clamping arm 4 is closed, this elastic force is converted into a pre-tightening force on clamping arm 4, so that the clamping wheel 5 clamps the tube not as a rigid impact, but achieves flexible contact and buffering, and can adapt to the slight differences of tubes with different diameters, ensuring that the clamping is stable and does not damage the surface of the tube.

[0027] When the cylinder needs to be released, the piston rod of the cylinder body 2 drives the clamping arm 4 to open. During this opening action, the spring 9 connected between the frame body 1 and the brake pad 8 is stretched. The tension of the spring 9 will pull the brake pad 8 hinged in the clamping arm 4 to rotate, so that the brake pad 8 contacts and rubs against the clamping wheel 5, thereby achieving rapid braking of the clamping wheel 5, preventing it from continuing to spin freely under inertia, and ensuring that the device operates accurately and responds quickly.

[0028] Insert a standard bobbin, check the limiting effect to ensure that the center of the bobbin is aligned with the winding center of the texturing machine wire, and then control the piston rod of the cylinder body 2 to retract and drive the clamping arm 4 to reset, and achieve effective clamping of the bobbin through the clamping wheel 5.

[0029] Please see Figure 1 and 2 The clamping arm 4 is equipped with a rack arm 401, which is located at the bottom of the clamping wheel 5.

[0030] In this invention, the rack arm 401 located at the bottom of the clamping wheel 5 can engage with the toothed groove at the end of the tube during the clamping process, providing additional circumferential positioning and anti-rotation functions, and further ensuring the stability of the tube during high-speed operation.

[0031] Please see Figure 1 The clamping arm 4 has an installation slot 402, and the clamping wheel 5 is installed inside the installation slot 402 by bolts.

[0032] In this invention, the clamping wheel 5 is bolted into the mounting groove 402 of the clamping arm 4, which facilitates adjustment or replacement according to the specifications of the tube.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
