Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for stenters, and in particular to a device for testing the uniformity of air jet during the operation of a stenter. Background Technology

[0002] In the textile printing and dyeing industry, the uniformity of airflow from the hot air duct of a setting machine directly determines the quality of fabric setting. Traditional verification methods rely on manual cold-state testing, requiring operators to crawl into the hot air duct and use a combination of tools to insert metal probes one by one into the air outlets to measure the air velocity. This method has two major drawbacks: first, hand-held operation leads to inconsistent probe positions and insertion depths, resulting in distorted measurement data; second, it is completely impossible to conduct testing under high-temperature conditions such as 160℃~220℃, causing the uniformity of airflow in actual production to be measured blindly for a long time. To address these industry pain points, this patent proposes a device for detecting the uniformity of airflow during the operation of a setting machine, thereby achieving accurate and consistent measurement of the hot air duct outlets under all operating conditions. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the uniformity of airflow during the operation of a shaping machine.

[0004] The innovation of this utility model lies in the mechanical positioning of the probe through the groove on the slide rail, which enables the probe to be accurately inserted into the hot air pipe outlet, thereby achieving accurate detection of the uniformity of air spray in the hot air pipe of the shaping machine under all working conditions, and solving the positioning deviation and high temperature detection blind spot of traditional manual detection.

[0005] To achieve the aforementioned objectives, the technical solution of this utility model is as follows: A device for detecting the uniformity of airflow during the operation of a setting machine, comprising a hot air pipe, a plurality of air outlets on the top surface of the hot air pipe, a slide rail arranged along the length of the hot air pipe, a detection component that moves along the slide rail, a plurality of probes for detecting the uniformity of airflow from the air outlets on the detection component, and a plurality of grooves on the slide rail. When the detection component moves to a groove, the probe of the detection component is inserted into the air outlet; when the detection component moves out of the groove, a gap exists between the probe and the upper surface of the hot air pipe. By adding a grooved slide rail along the length of the hot air pipe, the probe can be accurately inserted into the air outlet under the positioning of the groove, overcoming the positioning deviation and high-temperature blind zone of manual handheld detection, realizing dynamic measurement of the uniformity of airflow across the entire pipe section under all operating conditions, and improving the consistency of the detection data; when the detection component moves out of the groove, a gap exists between the probe and the upper surface of the hot air pipe, ensuring that the probe maintains a safe distance from the hot air pipe when the detection component is not detecting the air outlet, thus improving the stability of the overall device.

[0006] Furthermore, the detection assembly includes a bracket positioned above the hot air duct, and the probe is mounted on the bracket.

[0007] Furthermore, the slide rails are two in number and symmetrically arranged on both sides of the hot air duct. This symmetrical arrangement of slide rails on both sides ensures balanced force on the detection component, eliminating the risk of jamming or tilting caused by single-track movement, guaranteeing stable movement of the detection component, and improving detection efficiency and accuracy.

[0008] Furthermore, the bracket is provided with several sets of bearing assemblies that match the slide rails on both sides of the hot air duct. Each bearing assembly includes a rolling shaft with a bearing on it, and one end of the rolling shaft is connected to the bracket.

[0009] Furthermore, the outer diameter of the first bearing is equal to the diameter of the groove. By ensuring that the outer diameter of the first bearing is equal to the diameter of the groove, an interference fit interface is formed after the first bearing is inserted, ensuring consistent probe insertion depth and avoiding errors from repeated measurements.

[0010] Furthermore, the support frame is equipped with several secondary bearing assemblies that slide on the side of the hot air duct to maintain stable operation of the support frame. The addition of these secondary bearing assemblies provides extra lateral support force during support frame movement, ensuring stable operation.

[0011] Furthermore, the bracket is also equipped with an adjustment groove that matches the second bearing assembly and is used to adjust the second bearing assembly to move closer to or further away from the hot air duct. By fine-tuning the position of the second bearing through the adjustment groove, the probe on the detection assembly can be positioned according to the air outlet under different operating conditions.

[0012] Furthermore, the second bearing assembly includes a second rolling shaft installed within an adjustment groove. One end of the second rolling shaft is provided with a locking nut for fixing its position within the adjustment groove. A second bearing is mounted on the second rolling shaft, and the outer ring of the second bearing abuts against the side wall of the hot air duct. This design, using a locking nut to fix the second rolling shaft, allows for quick disassembly and replacement of the second bearing. The contact between the outer ring of the second bearing and the side wall of the hot air duct prevents measurement trajectory drift caused by uneven wear, ensuring the stability of the support operation and the accuracy of the detection.

[0013] Furthermore, the probe is a high-temperature resistant metal probe. By using a high-temperature resistant metal probe, the probe can operate continuously in high-temperature airflow, ensuring detection efficiency in high-temperature environments.

[0014] Furthermore, the bracket has a C-shaped structure. By adopting an open structure spanning the hot air duct above the C-shaped bracket, the bracket opening span is adjustable to accommodate hot air ducts of different widths; the C-shaped structure has good bending resistance, suppresses high-temperature thermal deformation, and ensures the levelness error of the detection components; it also facilitates the installation of the probe and the fit between the lifting and sliding tracks.

[0015] The beneficial effects of this utility model are: the probe is precisely inserted into the hot air pipe outlet by mechanical positioning through the groove on the slide, so as to realize accurate detection of the uniformity of air spray in the hot air pipe of the shaping machine under all working conditions, and solve the positioning deviation and high temperature detection blind spot of traditional manual detection.

[0020] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0021] Example: Figure 1 , 2As shown in Figures 3 and 4, a device for detecting the uniformity of airflow during the operation of a setting machine includes a hot air pipe 1. The top surface of the hot air pipe 1 has several air outlets 2. A slide rail 3 is arranged along the length of the hot air pipe 1. A detection component 4, which moves along the slide rail 3, is provided on the slide rail 3. The detection component 4 has several probes 5 for detecting the uniformity of airflow from the air outlets 2. The slide rail 3 has several grooves 6. When the detection component 4 moves to a groove 6, the probes 5 of the detection component 4 are inserted into the air outlets 2. When the detection component 4 moves out of the groove 6, a gap exists between the probes 5 and the upper surface of the hot air pipe 1. The detection component 4 includes a bracket 7 positioned above the hot air pipe 1, and the probes 5 are mounted on the bracket 7. Two slide rails 3 are symmetrically arranged on both sides of the hot air pipe 1. The bracket 7 is located on both sides of the hot air duct 1 and is equipped with several sets of first bearing assemblies 8 that match the slide rails 3 on both sides of the hot air duct 1. Each first bearing assembly 8 includes a first rolling shaft 81, on which a first bearing 82 is mounted. One end of the first rolling shaft 81 is connected to the bracket 7. The outer diameter of the first bearing 82 is equal to the diameter of the groove 6. The bracket 7 is equipped with several second bearing assemblies 9 that slide on the side of the hot air duct 1 to maintain the stable operation of the bracket 7. The bracket 7 is also equipped with an adjustment groove 10 that matches the second bearing assembly 9 and is used to adjust the second bearing assembly 9's proximity to or distance from the hot air duct 1. The second bearing assembly 9 includes a second rolling shaft 91 installed in the adjustment groove 10. One end of the second rolling shaft 91 is equipped with a locking nut 92 for fixing the second rolling shaft 91 in position within the adjustment groove 10. A second bearing 93 is mounted on the second rolling shaft 91, and the outer ring of the second bearing 93 abuts against the side wall of the hot air duct 1. The probe 5 is a high-temperature resistant metal probe. The bracket 7 has a C-shaped structure.

[0022] The working principle of this utility model is as follows: First, the bracket 7 is driven to move along the double slide rails 3 of the hot air duct 1 by manual pushing, motor traction, or automatic cruise device. When the first bearing 82 on both sides of the bracket 7 rolls to the groove 6 of the slide rail 3, the outer diameter of the first bearing and the groove 6 form an interference fit, forcing the first bearing to accurately lock into the groove 6. Second, when the first bearing 82 rolls to the groove of the slide rail, the high-temperature resistant metal probe fixed on the detection component 4 is simultaneously inserted into the center of the corresponding air outlet 2 to collect wind speed data. The second bearing component 8 is pre-tightened by the adjustment groove and abuts against the side wall of the hot air duct 1 to ensure the stable operation of the bracket 7 while adjusting the fine adjustment of the probe position of the detection component 4 to ensure that the probe accurately enters the air outlet 2 during detection. Subsequently, the bracket is driven to continue moving manually or by motor so that the first bearing 82 slides out of the groove, and the probe 5 is lifted with the bracket 7 and disengaged from the air outlet 2, forming a safe gap with the upper surface of the hot air duct 1 to avoid scratch damage. The above process is repeated to complete the dynamic detection of the entire hot air duct group by group, realizing online monitoring of the uniformity of air spray in the entire pipe section under all working conditions.

[0023] In summary, the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
