Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery testing equipment, specifically an automatic force setting mechanism for a rubber ring frame. Background Technology

[0002] Rubber apron: A key component of spinning equipment. The rubber apron typically consists of two circular rubber aprons, one on top and one on the bottom, hence the name. Its main function is to stably guide the fiber sliver and apply necessary control forces. The tension of the rubber apron is a crucial factor affecting key quality indicators such as fiber control, evenness, and breakage rate; therefore, testing of the rubber apron is necessary.

[0003] In existing technologies, the force measurement and adjustment of rubber ring frames involves manually measuring the force of each frame using a force gauge on a force measuring platform. The force is then adjusted by manually rotating the force-measuring stud at the bottom according to the target value. If the desired force value is not achieved the first time, the operation must be repeated multiple times. This method is inefficient and lacks accuracy, severely impacting the production efficiency and delivery cycle of rubber ring frames. Therefore, we propose an automatic force measurement and adjustment mechanism for rubber ring frames. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic force measurement and adjustment mechanism for a rubber ring frame, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic force-measuring and adjusting mechanism for a rubber band frame includes a base;

[0007] The base is equipped with a pressure mechanism and a testing mechanism;

[0008] The pressure mechanism includes a support arm connected to a base, a pressure block rotatably connected to the support arm, the inner side of the pressure block having an arc-shaped structure, and a top block rotatably connected inside the support arm, the top block abutting against the end of the pressure block.

[0009] Preferably, a stepper motor is fixedly connected to the bottom of the base, a tightening screw is rotatably connected to the bottom of the base, the end of the output shaft of the stepper motor is fixedly connected to the tightening screw, and a screw sleeve that meshes with the tightening screw is fixedly connected to the bottom of the base.

[0010] Preferably, a drive seat is fixedly connected to the end of the tightening screw, a drive frame is connected to the inner side of the drive seat, and a one-way bearing is connected between the drive seat and the drive frame.

[0011] Preferably, a second threaded sleeve is fixedly connected to the bottom of the inner side of the support arm, a test stud is engaged with the inner side of the second threaded sleeve, a buffer spring is connected to the top of the test stud, and the end of the buffer spring abuts against the bottom of the top block.

[0012] Preferably, the top of the drive frame has a prism-shaped structure, and the bottom of the test stud has a drive groove corresponding to the structure of the drive frame. The drive frame and the test stud are slidably connected.

[0013] Preferably, the testing mechanism includes a cylinder, which is fixedly connected to the bottom of the base. The base has through holes corresponding to the positions of the cylinder. A pressure sensor is fixedly connected to the output end of the cylinder, and the pressure sensor corresponds to the position of the pressure block.

[0014] By employing the above technical solution, this utility model provides an automatic force-measuring and adjusting mechanism for a rubber band frame, which has at least the following beneficial effects:

[0015] (1) The present invention can automatically apply force to the rubber ring frame by setting the pressure block on the inner side of the arc, so that the rubber ring frame can be tested and adjusted, thereby reducing the tedious manual operation and improving the efficiency of testing and adjusting the rubber ring frame. At the same time, the bottom of the base is equipped with a stepper motor, and the shaft end of the stepper motor is connected to a self-designed tightening screw. The pressure of the rubber ring frame can be adjusted by rotating the force measuring stud at the bottom according to the measured pressure. There is no need to manually remove the rubber ring frame from the force measuring table, rotate the force measuring stud, and then put it back on the force measuring table for testing.

[0016] (2) The present invention can drive the drive frame in one direction through the one-way bearing structure, so that the pressure block can be continuously pressed down during the test. The one-way bearing on the inner side of the drive seat makes the top drive frame rotate synchronously when the tightening screw is tightened upward, and the force measuring stud will be tightened by force. When the tightening screw is loosened downward, the top drive frame will not rotate but will descend vertically, thereby increasing the stroke of the force measuring stud.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] An automatic force-measuring and adjusting mechanism for a rubber band frame, such as Figures 1-5 As shown, it includes a base 1; a pressure mechanism 2 is provided on the base 1. The pressure mechanism 2 can apply force to the test rubber ring frame, thereby detecting and adjusting the downward pressure of the rubber ring frame. At the same time, the automatic force application structure reduces the operation of the operator and improves the test accuracy.

[0027] Specifically, the pressure mechanism 2 includes a support arm 201, which is connected to the base 1. The support arm 201 is mounted on the base 1 with bolts and nuts, allowing for easy disassembly and replacement to accommodate testing needs of rubber ring frames of different diameters. The support arm 201 also supports the structure used for pressure testing. A pressure block 202 is rotatably connected to the support arm 201. The inner side of the pressure block 202 has an arc-shaped structure, allowing it to rotate and test the rubber ring frame. The arc-shaped structure of the pressure block 202 closely matches the curvature of the rubber ring frame, thus applying uniform force to the outer side of the frame during testing. A top block 203 is rotatably connected inside the support arm 201, abutting against the end of the pressure block 202. The top block 203 and the bottom of the pressure block 202 are in contact. Rotation of the top block 203 drives the pressure block 202, causing it to rotate and perform the testing operation on the rubber ring frame.

[0028] It is worth noting that a stepper motor 204 is fixedly connected to the bottom of the base 1. The stepper motor 204 provides power to the test structure and can provide accurate driving force. By controlling the number of rotations of the output shaft of the stepper motor 204, the test pressure of the pressure block 202 can be precisely adjusted. A tightening screw 205 is rotatably connected to the bottom of the base 1. The end of the output shaft of the stepper motor 204 is fixedly connected to the tightening screw 205. A threaded sleeve 206 that meshes with the tightening screw 205 is fixedly connected to the bottom of the base 1. The stepper motor 204 can control the tightening screw 205, and the tightening screw 205 can cooperate with the threaded sleeve 206 to control the lifting and lowering through the rotation of the tightening screw 205.

[0029] Based on this, a drive seat 207 is fixedly connected to the end of the tightening screw 205, and a drive frame 208 is connected to the inner side of the drive seat 207. A one-way bearing 209 is connected between the drive seat 207 and the drive frame 208. The structure of the drive seat 207 can rotate with the tightening screw 205 and drive the drive frame 208 through the one-way bearing 209. At the same time, the structure of the one-way bearing 209 can only drive the drive frame 208 in one direction by the drive seat 207. When rotating in the opposite direction, it can keep the drive frame 208 from rotating. Therefore, the stroke of the pressure block 202 can be increased by the stepper motor 204 that rotates alternately in the forward and reverse directions.

[0030] In addition, a second threaded sleeve 210 is fixedly connected to the bottom of the support arm 201. A test stud 211 is engaged with the inner side of the second threaded sleeve 210. A buffer spring 212 is connected to the top of the test stud 211. The end of the buffer spring 212 abuts against the bottom of the top block 203. The second threaded sleeve 210 can cooperate with the test stud 211, and the lifting and lowering of the test stud 211 can be conveniently controlled by rotating the test stud 211.

[0031] Furthermore, the top of the drive frame 208 has a prismatic structure, and the bottom of the test stud 211 has a drive groove corresponding to the structure of the drive frame 208. The drive frame 208 and the test stud 211 are slidably connected. The drive frame 208, which is slidably connected inside the test stud 211, can facilitate the motor's control of the pressure block 202 after the support arm 201 is installed. At the same time, the length of the drive frame 208 can be reduced through the one-way bearing 209, which facilitates the installation of the support arm 201 and avoids the inconvenience of installing the support arm 201 due to the drive frame 208 being too long.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on Embodiment 1, a testing mechanism 3 is provided on the base 1. The testing mechanism 3 can test the leather ring frame and output the test results to the outside through an electrical signal.

[0034] In this embodiment, the testing mechanism 3 includes a cylinder 301, which is fixedly connected to the bottom of the base 1. The base 1 has a through hole 302 corresponding to the position of the cylinder 301. A pressure sensor 303 is fixedly connected to the output end of the cylinder 301. The pressure sensor 303 is corresponding to the position of the pressure block 202. The cylinder 301 can drive the pressure sensor 303 to move up and down, thereby adapting to the testing requirements of rubber ring frames of different diameters.

[0035] In use, the automatic force measurement and adjustment mechanism for a rubber band frame of this utility model first places the rubber band frame to be tested inside the pressure block 202, and then starts the motor to test and adjust the downward pressure on the rubber band frame. During the test, the tightening screw 205 rotates one revolution at a time under the drive of the stepper motor 204. When the tightening screw 205 rotates in the forward direction, the drive frame 208 rotates synchronously with the drive seat 207, and drives the test stud 211 to rotate synchronously. When the test stud 211 rotates, it continues to rise due to the drive of the screw sleeve 210, and pushes the top block 203 to rotate upward through the buffer spring 212, thereby increasing the test pressure of the pressure block 202 on the rubber band frame. At this time, the pressure sensor 303 supports the rubber band frame from the other side of the rubber band frame and acquires the pressure test data of the rubber band frame, and then converts the test data into a data signal for transmission. When the drive seat 207 is driven, the drive seat 207 rotates periodically in the forward and reverse directions under the drive of the stepper motor 204. When the drive seat 207 rotates in the reverse direction, due to the characteristics of the one-way bearing 209, the drive seat 207 cannot drive the drive frame 208 to rotate. At this time, the tightening screw 205 drives the drive seat 207 and the drive frame 208 to descend after rotating in the reverse direction, thereby resetting the drive frame 208 and facilitating the drive frame 208 to drive the test stud 211 again.
