Description

Technical Field

[0001] The utility model relates to polyester fiber testing, in particular to a device for crushing, blowing, collecting and preparing samples of polyester fibers. Background Art

[0002] When using XRF (X-ray fluorescence spectrometer) to semi-quantitatively test the element content in polyester fiber samples, since polyester fibers are filamentous samples with a certain length, in order to reduce the influence of the matrix effect of polyester fiber samples (the more uniform the test sample, the better) on the test results, the samples are processed and shredded (the smaller the better) before testing. The shredded polyester fibers are collected and tested after sample preparation.

[0003] Polyester fiber is widely used in textiles, industry and other fields. In order to conduct performance analysis and quality inspection on polyester fiber, it needs to be made into uniform small filament samples for testing. However, the traditional method of manual shredding and collection often has problems such as low efficiency, uneven samples, and easy contamination.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In response to the problems in the related art, the utility model proposes a device for crushing, blowing, collecting and sampling polyester fibers to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] The cam is fixedly connected to the rotating shaft of the L-shaped plate, and the top end of the L-shaped plate is provided with a sliding groove, and the sliding groove is slidably connected to the first cam, and the top end of the rotating shaft extends to the outside of the fixed frame and is connected to the output end of the rotating motor.

[0008] Furthermore, in order to transport the polyester fiber into the sample preparation cabinet, the sample delivery component includes a spiral rotating rod rotatably connected to the top end of the sample delivery pipe, the top end of the spiral rotating rod extends outside the sample delivery pipe and is connected to the output end of the sample delivery motor, and a sample delivery port is fixedly installed on the outer surface of the sample delivery pipe.

[0009] Furthermore, in order to facilitate the transportation of shredded samples to the bottom of the sample preparation cabinet for subsequent work, a purge machine is fixedly installed on the top of the sample preparation cabinet away from the end of the sample delivery pipe, and a purge pipe is fixedly provided at the output end of the purge machine. One end of the purge pipe extends into the sample preparation cabinet and is fixedly connected to a purge nozzle, and the purge nozzle is fixedly installed on the top of the inner surface of the sample preparation cabinet.

[0010] Furthermore, in order to filter the shredded samples, the inner surface of the sample preparation cabinet is rotatably connected to a filter shaft away from the bottom end of the fixed frame, and a second cam is symmetrically welded on the filter shaft. Grooves are provided on both ends of the inner surface of the sample preparation cabinet away from the top end of the filter shaft, and a first filter plate is slidably connected in the groove. A second filter plate is welded on the inner surface of the sample preparation cabinet away from the bottom end of the filter shaft.

[0011] Furthermore, in order to allow the first filter plate to move back and forth in the groove, fixing parts are welded on both ends of the inner surface of the sample preparation cabinet away from the top of the groove, and a second spring is symmetrically welded on the fixing parts, and the second spring is fixedly connected to the first filter plate.

[0012] Furthermore, in order to collect the filtered samples, a pull-out groove is provided on the inner surface of the sample preparation cabinet away from the bottom end of the filter shaft, and one end of the pull-out groove extends to the outside of the sample preparation cabinet and is slidably connected to the collection box.

[0013] Furthermore, in order to facilitate the rotation of the filter shaft, one end of the filter shaft extends outside the sample preparation cabinet and is connected to the output end of the filter motor. A controller is fixedly installed outside the sample preparation cabinet away from the top of the filter motor, and the controller is electrically connected to the filter motor.

[0014] Furthermore, in order to facilitate personnel to observe the working conditions in the sample preparation cabinet, an observation window is fixedly installed on one side of the outer surface of the sample preparation cabinet.

[0015] The beneficial effects of the utility model are:

[0016] 1. The polyester fiber is placed in the sample delivery pipe through the sample delivery port. The sample delivery motor starts working and drives the spiral rotating rod to rotate. The rotation of the spiral rotating rod causes the polyester fiber to flow along the sample delivery pipe into the sample preparation cabinet. By installing a light sensor, the sample feeding is automated, which saves manpower and further improves the test efficiency.

[0017] 2. The rotating motor works, driving the rotating shaft to rotate and causing the first cam to rotate in the side groove. The rotation of the first cam contacts the sliding groove, causing the L-shaped plates to approach each other and the first spring between the L-shaped plates to be in a compressed state. The L-shaped plates move relative to each other and the shear blades move accordingly. The movement of the shear blades shreds the polyester fibers, enabling the polyester fibers to be shredded into uniform samples for testing, thereby greatly improving the shredding efficiency.

[0018] 3. The blower works by blowing away the shredded samples through the blower nozzle. Blowing makes it easier to collect and clean the samples and eliminates the static adsorption of polyester fibers.

[0019] 4. The purge machine works and blows the shredded sample to the first filter plate through the purge nozzle. At this time, the filter motor works, and the filter motor drives the filter shaft to rotate, and the second cam rotates accordingly. Under the action of the second spring, the first filter plate is always in contact with the second cam. The rotation of the second cam makes the first filter plate slide back and forth in the groove, thereby filtering the sample on the first filter plate. The sample passing through the first filter plate falls onto the second filter plate, and the second filter plate filters the sample again, which can achieve multi-stage filtration of the sample, thereby effectively separating the sample and impurities, and at the same time, avoiding clogging of the first filter plate.

[0036] See also Figure 1 and Figure 2The filter housing 20 is provided with a filter shaft 20 which is rotatably connected to the filter housing 20 and is away from the bottom end of the fixing frame 10. A second cam 21 is symmetrically welded on the filter shaft 20. A groove 22 is provided on both ends of the inner surface of the sample preparation cabinet 1 away from the top end of the filter shaft 20. A first filter plate 23 is slidably connected in the groove 22. In order to enable the first filter plate 23 to move back and forth in the groove 22, a fixing piece 25 is welded on both ends of the inner surface of the sample preparation cabinet 1 away from the top end of the groove 22. A second spring 24 is symmetrically welded on the fixing piece 25. The second spring 24 has a certain elasticity. The second spring 24 is fixedly connected to the first filter plate 23. A second filter plate 30 is welded on the inner surface of the sample preparation cabinet 1 away from the bottom end of the filter shaft 20.

[0037] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0038] In actual application, first, the polyester fiber is placed in the sample delivery pipe 2 through the sample delivery port 5, and the controller 28 starts the sample delivery motor 4, which drives the spiral rotating rod 3 to rotate. The rotation of the spiral rotating rod 3 causes the polyester fiber to flow along the sample delivery pipe 2 to the sample preparation cabinet 1. The polyester fiber is between the receiver and the transmitter, causing the receiver to be unable to receive the light emitted by the transmitter. At this time, the controller 28 starts the rotating motor 16, which drives the rotating shaft 17 to rotate and causes the first cam 18 to rotate in the side groove 11. The rotation of the first cam 18 contacts the sliding groove 15, causing the L-shaped plates 13 to approach each other and the first spring 14 between the L-shaped plates 13 to be in a compressed state. The L-shaped plates 13 move relative to each other and cause the shear blade 12 to move accordingly. The movement of the shear blade 12 thereby cuts the polyester fiber. The shredding process is performed. Secondly, the controller 28 enables the blower 7 to work, and the shredded sample is blown to the first filter plate 23 through the blower nozzle 9. Then, the controller 28 enables the filter motor 19 to work, and the filter motor 19 drives the filter shaft 20 to rotate, and causes the second cam 21 to rotate accordingly. Under the action of the second spring 24, the first filter plate 23 is always in contact with the second cam 21. The rotation of the second cam 21 causes the first filter plate 23 to slide back and forth in the groove 22, thereby filtering the sample on the first filter plate 23. The sample passing through the first filter plate 23 falls onto the second filter plate 30, and the second filter plate 30 filters the sample again, which can enable the sample to achieve multi-stage filtration, thereby effectively separating the sample and impurities. Finally, the filtered sample falls into the collection box 27 for centralized collection.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
