Description

Technical Field

[0001] This utility model relates to the technical field of textile thread support for large circular knitting machines, specifically a support for textile threads on large circular knitting machines with adjustable height. Background Technology

[0002] In the textile industry, circular knitting machines are commonly used equipment. Traditional textile thread supports suffer from problems such as inconvenient height adjustment and poor precision. Different textile processes have different requirements for the height of textile threads. If the height cannot be adjusted precisely, it will easily lead to uneven tension of the textile threads, affecting the quality of the fabric and thus limiting production efficiency and product diversification. Therefore, we propose a textile thread support with precise height adjustment for circular knitting machines.

[0003] The existing technology still has the following drawbacks in its use:

[0004] The height of the adjustable textile thread support on the existing circular knitting machine is not convenient to adjust. Due to the small installation spacing between the supports and the dense installation of the supports on the circular knitting machine, the supports cannot be adjusted manually. In addition, the traditional threaded adjustment method has wear problems and has large errors after a long period of use.

[0005] In existing circular knitting machines, the height-adjustable support for the spinning thread can only be adjusted in a simple way. As the spinning thread is output, the outer diameter of the roller that winds the thread changes, which causes the center position of the roller to change. Traditional supports cannot make corresponding correction adjustments for the displacement of the roller, which reduces the output accuracy of the spinning thread of the circular knitting machine.

[0006] In view of this, we propose a height-adjustable support for textile threads on a large circular knitting machine to solve the existing problems. Utility Model Content

[0007] The purpose of this invention is to provide a support for textile threads with adjustable height on a large circular knitting machine, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a support for a precisely adjustable height textile thread on a large circular knitting machine, comprising a fixed frame, a mounting sleeve and a telescopic rod, wherein a hydraulic actuator is fixedly installed on the top left side of the mounting sleeve, a main control box is fixedly installed on the top right side of the mounting sleeve, and two connecting plates are fixedly installed on the bottom of the mounting sleeve.

[0009] A fixing frame is installed on the left side of the mounting sleeve. The fixing frame is an L-shaped plate, and two sets of fixing bolts are installed inside the fixing frame through a threaded structure. A connecting frame is installed on the top of the fixing frame through a hinge, and the right side of the connecting frame is fixedly connected to the mounting sleeve.

[0010] The mounting sleeve has a telescopic rod extending to the right side of the mounting sleeve. A rotating shaft is fixedly installed on the right side of the telescopic rod near the bottom. An active frame is fixedly installed on the right side of the rotating shaft. The active frame has a V-shaped structure, and two pneumatic push rods are mounted on the left side of the active frame via pins. One end of each pneumatic push rod is fixedly connected to the telescopic rod. A second support roller is mounted on the inner side of the active frame near the top via a bearing. A level sensor is fixedly installed on the top of the active frame, and a limit rod is fixedly installed inside the active frame. A driven frame is slidably installed on the other side of the limit rod. A distance sensor is installed on the top of the active frame near the driven frame, and propulsion cylinders are fixedly installed on both the front and back of the distance sensor on the top of the active frame.

[0011] Preferably, the mounting sleeve is a hollow cylindrical object with a triangular cross-section, and a triangular opening is provided on the right side of the mounting sleeve, while the left side of the mounting sleeve is a solid structure.

[0012] Preferably, a hydraulic push rod is installed on the right side of the fixing frame via two contact plates and a through shaft, and the other end of the hydraulic push rod is connected to the connecting plate shaft at the bottom of the mounting sleeve.

[0013] Preferably, a first support roller is mounted on the inner side of the driven frame via a bearing, and the first support roller and the second support roller are on the same horizontal plane.

[0014] Preferably, one end of the propulsion cylinder is fixedly connected to the driving frame, and the other end of the propulsion cylinder is fixedly connected to the driven frame.

[0015] Preferably, the telescopic rod is a triangular rod-shaped object, and the surface of the telescopic rod is provided with three sets of limiting grooves, which are engaged with the mounting sleeve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention employs a retractable and flip-up bracket structure to install the first and second support rollers. This allows the roller with the woven yarn wound on it to autonomously adjust its height and tilt angle when placed between the first and second support rollers. This replaces manual adjustment of the horizontal and vertical positions of the bracket, placing the roller with the woven yarn wound in the optimal working position. This improves the support effect of the bracket on the woven yarn roller, avoids the wear problems of traditional adjustment structures, and ensures the accuracy of the bracket adjustment structure.

[0018] This invention connects the active frame and the driven frame using a limiting rod and a propulsion cylinder, allowing the driven frame to move to one side of the active frame. This adjusts the distance between the first and second support rollers, ensuring that as the amount of textile thread on the outer side of the drum gradually decreases, the center of the drum remains in the same position by adjusting the distance between the first and second support rollers. This keeps the output angle of the textile thread consistent and improves the output accuracy of the circular knitting machine. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, the present invention proposes a support for a precisely adjustable height textile thread on a large circular knitting machine, comprising a fixed frame 1, a mounting sleeve 2 and a telescopic rod 3. A hydraulic actuator 202 is fixedly installed on the top left side of the mounting sleeve 2, and a main control box 201 is fixedly installed on the top right side of the mounting sleeve 2. Two connecting plates are fixedly installed on the bottom of the mounting sleeve 2. The hydraulic actuator 202 can provide a power source for the telescopic movement of the telescopic rod 3, and the main control box 201 is used to control and coordinate the operation of the entire support.

[0027] A fixing frame 1 is installed on the left side of the mounting sleeve 2. The fixing frame 1 is an L-shaped plate, and two sets of fixing bolts are installed inside the fixing frame 1 through a threaded structure. A connecting frame 101 is installed on the top of the fixing frame 1 through a hinge, and the right side of the connecting frame 101 is fixedly connected to the mounting sleeve 2. The fixing frame 1 is convenient for installation and fixing with equipment such as large circular knitting machines. The two sets of fixing bolts can ensure the firmness of the connection between the fixing frame 1 and other components. The connecting frame 101 can rotate, and the right side of the connecting frame 101 is fixedly connected to the mounting sleeve 2, thereby realizing a stable connection between the fixing frame 1 and the mounting sleeve 2.

[0028] The mounting sleeve 2 has a telescopic rod 3 extending to its right side. A rotating shaft 301 is fixedly mounted near the bottom of the right side of the telescopic rod 3. An active frame 304 is fixedly mounted on the right side of the rotating shaft 301. The active frame 304 has a V-shaped structure, and two pneumatic push rods 307 are mounted on its left side via pins. One end of each pneumatic push rod 307 is fixedly connected to the telescopic rod 3. A second support roller 306 is mounted on the inner side of the active frame 304 near the top via a bearing. A horizontal sensor 309 is fixedly installed on the top of the active frame 304, and a limit rod 310 is fixedly installed inside the active frame 304. A driven frame 302 is slidably installed on the other side of the limit rod 310. A distance sensor 308 is installed on the top of the active frame 304 near the driven frame 302. A propulsion cylinder 303 is fixedly installed on both the front and back of the distance sensor 308 on the top of the active frame 304. The telescopic rod 3 can cooperate with the mounting sleeve 2 to adjust the overall length of the support, thereby allowing the support to be raised to a certain angle. After adjustment, the height of the support can be adjusted within a certain range. The rotating shaft 301 can rotate the active frame 304 to facilitate angle adjustment of the active frame 304 and the driven frame 302. The pneumatic push rod 307 can push the active frame 304 to rotate around the rotating shaft 301. The second support roller 306 cooperates with the first support roller 305 to place the roller wound with the textile thread on top of the support, thereby facilitating the winding and unwinding of the textile thread on the outside of the roller. The horizontal sensor 309 adopts the GUD360 type and is a horizontal sensor. Device 309 can detect the tilt angle of the active frame 304, thereby facilitating the leveling of the active frame 304. Distance sensor 308 can detect the position of the roller, and then adjust the distance between the first support roller 305 and the second support roller 306 by controlling the extension and retraction of the propulsion cylinder 303, thereby achieving fine adjustment of the roller. Limiting rod 310 can limit the active frame 304 and the driven frame 302, so that the driven frame 302 can remain stable when it is pushed by the propulsion cylinder 303.

[0029] Furthermore, the mounting sleeve 2 is a hollow cylindrical object with a triangular cross-section, and a triangular opening is provided on the right side of the mounting sleeve 2. The left side of the mounting sleeve 2 is a solid structure, and the right side of the mounting sleeve 2 is provided with a triangular opening to facilitate the extension and retraction of the telescopic rod 3.

[0030] Furthermore, a hydraulic push rod 102 is installed on the right side of the fixed frame 1 via two contact plates and a through shaft, and the other end of the hydraulic push rod 102 is connected to the connecting plate shaft at the bottom of the mounting sleeve 2. The hydraulic push rod 102 pushes the mounting sleeve 2 to rotate around the fixed frame 1, thereby realizing the height adjustment of the bracket within a certain range.

[0031] Furthermore, a first support roller 305 is mounted on the inner side of the driven frame 302 via a bearing, and the first support roller 305 and the second support roller 306 are on the same horizontal plane. The first support roller 305 and the second support roller 306 are on the same horizontal plane, and together they support the roller that winds the textile thread, ensuring that the textile thread remains stable during operation.

[0032] Furthermore, one end of the propulsion cylinder 303 is fixedly connected to the active frame 304, and the other end of the propulsion cylinder 303 is fixedly connected to the driven frame 302. By extending and retracting the propulsion cylinder 303, the distance between the active frame 304 and the driven frame 302 can be precisely adjusted, so as to adjust the distance between the first support roller 305 and the second support roller 306, thereby keeping the rollers placed on top of the first support roller 305 and the second support roller 306 in the same position to output the textile thread.

[0033] Furthermore, the telescopic rod 3 is a triangular rod-shaped object, and three sets of limiting grooves are opened on the surface of the telescopic rod 3. The limiting grooves are engaged with the mounting sleeve 2. The three sets of limiting grooves on the surface of the telescopic rod 3 and the engaging connection between the limiting grooves and the mounting sleeve 2 can ensure the stability and accuracy of the telescopic rod 3 during the extension and retraction process and prevent shaking and other situations.

[0034] Working principle: During textile operations, the hydraulic push rod 102 is activated via the main control box 201. The hydraulic push rod 102 then pushes the mounting sleeve 2 to rotate around the hinge at the top of the fixed frame 1, thereby allowing the overall support to make a preliminary height adjustment within a certain range. After the preliminary height adjustment is completed, if a more precise height fine-tuning is required, the hydraulic actuator 202 is controlled via the main control box 201. The hydraulic actuator 202 drives the telescopic rod 3 to extend and retract within the mounting sleeve 2, thus completing the height fine-tuning. The water level of the active frame 304 is monitored in real time by the level sensor 309. When the active frame 304 tilts, the main control box 201 controls the pneumatic push rod 307 to extend and retract, changing the angle of the active frame 304 and restoring it to a horizontal state. At the same time, the distance sensor 308 monitors the distance from the bottom rollers of the first support roller 305 and the second support roller 306 to the distance sensor 308 in real time and feeds the data back to the main control box 201. When the textile thread gradually decreases, it is necessary to adjust the distance between the active frame 304 and the driven frame 302 to ensure that the center of the roller is always in the same position.

[0035] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
