Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament production, in particular to a toughness detection device for polyester filament production. Background Technique

[0002] The characteristics of polyester filament are that it can withstand chemical substances and frequent washing, reducing the phenomenon of clothing fading and decolorization. Therefore, hotel uniforms, stone-washed blue denim clothes, sportswear or children's clothing are all made of polyester filament. Relatively speaking, polyester filament is tougher than rayon. When embroidering, the machine runs at high speed, and the polyester thread with high toughness can also withstand greater tensile force. Therefore, the toughness of polyester filament will be detected during the production of polyester filament.

[0003] When some existing detection devices are in use, they cannot well clamp and fix the polyester filament stably. The polyester filament is easy to fall off from the detection device, and the stability is poor, which greatly affects the accuracy during the test. Content of the Utility Model

[0004] The purpose of the utility model is to provide a toughness detection device for polyester filament production to solve the problems in the above background technique in view of the defects of the existing technology.

A connecting head is provided at the top of the tensile force sensor. The traction wire is wound on the wire reel and is guided through the top end of the motor and connected to the connecting head through the wire guiding wheel;

[0006] The fixing component includes a housing, an adjusting screw, a limiting block and a moving seat. A placing groove is formed in the middle of one end face of the housing. The adjusting screw is rotatably installed at one end of the housing. The moving seat slides in the housing and is rotatably connected to the end of the adjusting screw. The limiting block is installed at the other end of the housing and is correspondingly arranged at the opening of the moving seat.

[0007] By adopting the above technical solution, it is convenient to place the polyester filament and stably fix the polyester filament, avoiding the phenomenon of slipping off of the polyester filament during the detection process.

[0008] A lifting rod fixedly connected to the connecting head also vertically penetrates through the support.

[0009] By adopting the above technical solution, the vertical up-and-down movement of the fixing component is restricted.

[0010] The lowest horizontal plane of the placement groove is located on the horizontal plane at the middle and lower part of the opening of the moving seat.

Detailed implementation

[0022] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0023] Refer to Figures 1-3 , a toughness detection device for polyester filament production, including a support 1 and a detection mechanism installed on the support 1. The detection mechanism includes a motor 2, a wire take-up wheel 3, a wire guide wheel 4, a towing line 6, a tension sensor 7, and a fixing component 8. The motor 2 is installed at the top end of the support 1, the wire take-up wheel 3 is installed at the output end of the motor 2. There are two groups of fixing components 8, which are arranged in an up-and-down corresponding manner. The lower group of fixing components 8 is fixed to the bottom of the support 1 through a connecting frame 9, and the upper group of fixing components 8 is connected to the tension sensor 7 through a connecting frame 9. A connecting head 10 is provided at the top of the tension sensor 7. The towing line 6 is wound around the wire take-up wheel 3 and is guided through the top end of the motor 2 by the wire guide wheel 4 and connected to the connecting head 10;

[0024] The fixing component 8 includes a housing 801, an adjusting screw 802, a limiting block 803, and a moving seat 804. A placement groove 8011 is opened in the middle of one end face of the housing 801. The adjusting screw 802 is rotatably installed at one end of the housing 801. The moving seat 804 slides in the housing 801 and is rotatably connected to the end of the adjusting screw 802. The limiting block 803 is installed at the other end of the housing 801 and is correspondingly arranged with the opening of the moving seat 804.

[0025] The polyester filament can be first placed in the placement groove 8011 at the housing 801 of the upper group of fixing components 8. Then, the adjusting screw 802 can be rotated to push the moving seat 804 to move inside the housing 801, and the polyester filament is clamped by the moving seat 804 and the limiting block 803. And because the outer wall of the moving seat 804 is made of rubber, the polyester filament stuck between the outer wall of the moving seat 804 and the inner wall of the housing 801 can also be further limited by the moving seat 804 and the inner wall of the housing 801, so that the polyester filament can be more stably fixed and restricted in the fixing component 8; Similarly, the other end of the polyester filament is placed in the lower group of fixing components 8 for fixation, and the limitation of both ends of the polyester filament is completed;

[0026] At this time, the driving motor 2 can drive the wire winding wheel 3 to wind the traction wire 6. The traction wire 6 then pulls the tension sensor 7 to move upward through the connector 10. The tension sensor 7 synchronously drives the fixed component 8 to move. The toughness of the polyester filament is detected based on the data measured by the tension sensor 7.

[0027] The setting of the lifting rod 5 enables the upper set of fixed components 8 to move vertically upward, preventing the upper set of fixed components 8 from shaking.

[0028] The support 1 is also vertically penetrated by a lifting rod 5 fixedly connected to the connector 10. A fixing plate is installed on one side of the connector 10. One end of the lifting rod 5 is fixed to the fixing plate, and the other end penetrates the support 1. And a flange is integrally provided at the top end of the lifting rod 5. The diameter of the flange is larger than the diameter of the lifting rod 5 and the diameter of the through hole on the support 1 for the lifting rod 5 to penetrate.

[0029] The lowest horizontal plane of the placement groove 8011 is located on the horizontal plane at the middle and lower part of the opening of the moving seat 804. After the polyester filament is placed in the placement groove 8011, the moving seat 804 is pushed to move. The opening of the moving seat 804 can clamp the polyester filament until the polyester filament is restricted in the opening of the moving seat 804 through the cooperation of the limit block 803, that is, the restriction of the polyester filament is completed.

[0030] The two legs of the connecting frame 9 are located on both sides of the placement groove 8011 and are fixed to the housing 801, and the middle position of the connecting frame 9 is correspondingly arranged with the middle position of the placement groove 8011. A distance is left between the connecting frame 9 and the housing 801 to facilitate placing the polyester filament in the placement groove 8011 and stably limiting the polyester filament through the fixed component 8. The openings of the placement grooves 8011 of the two sets of fixed components 8 are arranged on the opposite side surfaces. It is convenient to place the polyester filament and stably fix the polyester filament.

[0031] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
