Description

Technical Field

[0001] This utility model relates to the field of tire processing and manufacturing, and in particular to an automatic detection device for the stability of a tire semi-finished product extrusion line. Background Technology

[0002] A tire semi-finished product extrusion line is an automated production line for producing tire semi-finished products. Its operation includes the continuous and coordinated processing of plasticizing and extruding rubber, molding and shaping, cold bonding, and winding. During the production process, the stability of the extrusion line is a key factor in product quality and requires regular testing. Currently, the testing of extrusion line stability mainly relies on manual operation. Specifically, workers use a handheld punching device to punch holes in the product, and then measure the distance between the holes in each section to determine the shrinkage state of the extrusion line and whether there is any stretching.

[0003] Existing manual puncture inspection methods have several problems: First, when puncturing tires manually, the varying force, angle, and frequency of each person's operation can lead to inconsistencies in the depth and location of the punctures. Second, since tire products are cooled by water, it is difficult for humans to accurately measure the puncture location, resulting in inaccurate subsequent measurements and affecting the assessment of the stability of the production line. Third, workers need to operate on a high-speed production line where equipment operates at high speeds and some parts are exposed, posing a significant safety hazard as workers are easily injured or caught in the equipment. Fourth, manual inspection is inefficient, unable to monitor the stability of the production line in real time, and cannot promptly identify problems in the production process, potentially leading to a large number of defective products.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The present invention aims to address the shortcomings of the aforementioned technologies, to make the inspection of tire semi-finished product extrusion lines more intelligent, to improve inspection efficiency and accuracy, and to reduce safety hazards in the production process, by providing an automatic detection device for the stability of tire semi-finished product extrusion lines.

[0006] The specific technical solution provided by this utility model is as follows:

[0007] An automatic stability detection device for a tire semi-finished product extrusion line includes:

[0008] An automatic marking mechanism is installed at the receiving section of the extrusion line to automatically mark the products passing through the receiving section by printing marking dots with preset intervals.

[0009] The light detection assembly is set in multiple sets, which are installed at the rear end of each floating roller of the extrusion line. Each light detection assembly includes a light source and a photoelectric sensor. The light source shines on the product, and the photoelectric sensor detects the marked point under the action of the light source and transmits the signal.

[0010] The control mechanism is electrically connected to the automatic signage mechanism and the light detection component, and coordinates and controls the operation of the automatic signage mechanism and the light detection component through signal transmission.

[0011] Furthermore, the automatic marking mechanism includes a high-precision inkjet printer, which is fixed above the take-up section of the extrusion line by a bracket;

[0012] The inkjet printer is equipped with a printhead that faces the top surface of the product.

[0013] Furthermore, multiple sets of light detection components are respectively installed at any of the following locations or all of the following locations: after the forced shrinking device of the extrusion line, before and after the uphill transmission mechanism, the upper cooling device, the inflection point of the upper and lower cooling devices, before the downhill transmission mechanism, the downhill transmission mechanism, the blowing device, the rear end meter scale, the uphill device before winding, the first winding device, and the second winding device.

[0014] Furthermore, the light source is mounted on one side of the product via an adjustable bracket, and the light source emits parallel light that shines onto the product;

[0015] A photoelectric sensor is installed on the other side of the product, opposite to the light source, to receive light reflected or transmitted through the product.

[0016] Furthermore, the light source uses high-brightness LED lights.

[0017] Furthermore, the photoelectric sensor is electrically connected to the control mechanism, and the photoelectric sensor converts the detected light signal into an electrical signal and transmits it to the control mechanism.

[0018] Furthermore, the preset interval for the marking points is one marking point printed every 500mm.

[0019] Furthermore, it also includes a data processing terminal, which is electrically or signal-connected to the control mechanism, and is used to receive data transmitted by the control mechanism, and to store, analyze and display the data.

[0020] The automatic detection device for the stability of tire semi-finished product extrusion lines proposed in this utility model has the following beneficial technical effects compared with the prior art:

[0021] (1) The automatic marking mechanism is used for marking, which ensures the consistency of the interval and position of the marking points. The fixed length data is obtained by the light detection component and the control mechanism, which avoids the subjective error of manual measurement and improves the accuracy and intelligence of the detection.

[0022] (2) The automatic detection device can detect and process data of each section of the product in real time, without the need for manual measurement and recording, which greatly improves the detection efficiency and reduces labor costs.

[0023] (3) The entire testing process does not require manual operation at the production line. Workers only need to monitor the testing situation through the data processing terminal in the control room, which avoids the risk of workers being accidentally injured by the equipment and eliminates safety hazards.

[0024] (4) The data processing terminal can display the detection data in real time and store the data, which makes it convenient for staff to monitor the stability of the linkage line in real time. When the product has quality problems, the cause can be found by tracing historical data. Attached Figure Description

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0034] As attached Figure 1-2 As shown, an automatic stability detection device for a tire semi-finished product extrusion line includes:

[0035] Automatic marking mechanism 4 is set in the receiving section of extrusion line 110 to automatically mark products passing through the receiving section and print marking dots with preset intervals.

[0036] Multiple sets of light detection components 100 are provided and are installed at the rear end of each floating roller of the extrusion line 110. Each set of light detection components 100 includes a light source and a photoelectric sensor. The light source shines on the product, and the photoelectric sensor detects the marking point under the action of the light source and transmits the signal.

[0037] The control mechanism 130 is electrically connected to the automatic signage mechanism 4 and the light detection component 100 respectively, and coordinates and controls the operation of the automatic signage mechanism 4 and the light detection component 100 through signal transmission.

[0038] It should be further explained that the automatic marking mechanism 4 prints marking points, and the light detection component 100 monitors the product's operation on the extrusion line 110 by detecting these marking points. Specifically, the light detection component records the pulse signal time difference (Δt) between two adjacent marking points within the same detection section. 实 ), and combine the actual product speed (v) at that moment to calculate the actual interval distance (fixed length data) "L". 实 =v×Δt实 And compared with the theoretical interval L, the deviation value "ΔL=L" is obtained. 实 "-L" reflects the stability of the extrusion line 110 in real time through the calculated deviation value. If the extrusion line 110 experiences unstable conditions such as speed fluctuations or tension changes, the detection data at the marked points can be detected in a timely manner, allowing managers to take timely measures to adjust and ensure the quality of the semi-finished tire 120.

[0039] Obviously, through the coordinated operation of the automatic marking mechanism 4, the light detection component 100 and the control mechanism 130, this application can automatically detect the stability of the tire semi-finished product 120 extrusion line 110 without the need for frequent manual observation and measurement, thereby improving the efficiency and accuracy of detection and reducing errors caused by human factors.

[0040] As an embodiment of this application, the automatic marking mechanism 4 includes a high-precision inkjet printer, which is fixed above the take-up section of the extrusion line 110 by a bracket 150.

[0041] The inkjet printer is equipped with a printhead that faces the top surface of the product.

[0042] The automatic marking mechanism 4 is located at the receiving section of the extrusion line 110, that is, at the rear end of the extruder head 11, and marks the tire semi-finished product 120 extruded by the extruder 1 with inkjet printing.

[0043] Furthermore, the high-precision inkjet printer used in this application comprises a printhead, a printing media supply structure, a drive control module, and a bracket 150 for fixing. The printhead is the core execution component that is directly facing the upper surface of the product. It has a built-in fine nozzle that can accurately spray the printing media (ink or laser) onto the product surface, ensuring that the marking points are clear, accurate, and conform to the preset interval.

[0044] The inkjet printing media supply structure includes an ink tank, an ink pump, and a filter. The output end of the ink tank is connected to the filter through an ink output pipe. The filter is connected to the ink pump. The ink pump is connected to the filter at one end and to the nozzle at the other end through another ink output pipe. Under the operation of the filter, the inkjet printing media supply structure stably outputs clean ink with stable pressure.

[0045] The drive control module is connected to the control mechanism 130 by signal, and is used to receive the output signal of the control mechanism 130, control the printing timing and frequency of the printhead, match the running speed of the extrusion line 110, and ensure that the preset interval of the marking points is accurately achieved.

[0046] Furthermore, the bracket 150 serves as the load-bearing mounting structure for the inkjet printer, including a support portion and a mounting portion. The support portion supports the main structure of the inkjet printer, while the mounting portion is used for mounting and securing the inkjet printer. The bottom of the support portion can be fixed to a horizontal mounting platform or to the support frame of the extrusion line 110 take-up section (forced shrinkage device 2). Those skilled in the art can choose according to the actual situation, as long as the inkjet printer is fixed above the product and the relative position of the printhead and the upper surface of the product remains unchanged.

[0047] Furthermore, the bracket 150 can also be equipped with a position adjustment mechanism, which facilitates fine-tuning of the bracket 150 up and down and forward and backward, making it easy to calibrate the distance and facing angle between the nozzle and the product, and adapting to tire semi-finished products 120 of different thicknesses and widths.

[0048] The inkjet printer, fixed by bracket 150, can accurately print marking dots on the product, ensuring the accuracy of the marking dots. The working principle for achieving accurate inkjet printing is as follows:

[0049] The extrusion line 110 has a built-in meter counter encoder that records the distance in meters. The control mechanism 130 calculates the trigger time for each inkjet print based on the data (distance in meters) collected by the encoder and according to the preset marking point interval parameters (e.g., 500mm / marker), and then outputs a precise trigger command to the inkjet printer.

[0050] When the front end of the product passes the starting position sensor (such as a photoelectric switch) of the receiving section, the control mechanism 130 starts timing. Every time a Δt moment is reached (reaching a preset interval), an electrical signal is immediately sent to the inkjet printer of the automatic marking mechanism 4 to drive the printhead to print a marking point.

[0051] As an embodiment of this application, the light detection component 100 is provided with 10-15 sets. Multiple sets of light detection components 100 are respectively provided at any of the following locations or all of the following: after the forced shrinkage device 2 of the extrusion line 110, before and after the uphill transmission mechanism 5, the upper cooling device 7, the inflection point of the upper and lower cooling devices, before the downhill transmission mechanism 6, the downhill transmission mechanism 6, the blowing device 8, the rear end meter scale 9, the uphill device before winding, the first winding device 13, and the second winding device 14.

[0052] For example, the light detection assembly is provided with 12 groups, as shown in the attached diagram. Figure 2As shown, the positions of the 12 light detection components are as follows: a first light detection component 31 is set after the forced shrinkage device 2 of the extrusion line 110 (before the front end of the front end scale 3); a second light detection component 51 is set at the front end of the uphill transmission mechanism 5; a third light detection component 71 is set at the rear end of the uphill transmission mechanism 5 (the starting end of the upper cooling device 7); a fourth light detection component 72 is set on the upper cooling device 7; a fifth light detection component 121 is set at the inflection point between the upper cooling device 7 and the lower cooling device 12; and a sixth light detection component 122 is set at the end of the lower cooling device 12.

[0053] A seventh light detection component 61 is provided in the middle of the downhill transmission mechanism 6, an eighth light detection component 81 is provided at the beginning of the blowing device 8, a ninth light detection component 91 is provided at the beginning of the rear meter scale 9, a tenth light detection component 101 is provided on the uphill device 10 before winding, an eleventh light detection component 131 is provided on the first winding device 13 (winding section 1), and a twelfth light detection component 141 is provided on the second winding device 14 (winding section 2).

[0054] Light detection components are installed at many key locations, such as after the forced shrinkage device 2 of the extrusion line 110 of the tire semi-finished product 120 and before and after the uphill transmission mechanism 5. When the product carrying the marker passes through each detection point, the control mechanism 130 realizes quantitative monitoring of the extrusion stability of the production line through the signal feedback of the photoelectric sensor. It can comprehensively monitor the product at different stages of the extrusion line 110 and promptly detect problems in the operation stability of the extrusion line 110 caused by the operation of different equipment.

[0055] As an embodiment of this application, each light detection assembly 100 includes a light source and a photoelectric sensor. The light source is mounted on one side of the product via an adjustable bracket 150, and emits parallel light that illuminates the product. The photoelectric sensor is mounted on the other side of the product, opposite to the light source, and is used to receive light reflected or transmitted through the product.

[0056] Furthermore, the light source uses high-brightness LEDs, which provide stable and sufficiently intense light, ensuring that the photoelectric sensor can clearly receive the light reflected or transmitted through the product, thus improving the reliability of the detection.

[0057] Furthermore, the photoelectric sensor is electrically connected to the control mechanism 130, and the photoelectric sensor converts the detected light signal into an electrical signal and transmits it to the control mechanism 130.

[0058] The principle by which the aforementioned light source, photoelectric sensor, and control mechanism 130 work together to detect the stability of the extrusion line 110 is as follows:

[0059] The above-mentioned light source and photoelectric sensor are used to collect the signal of the marking point. The photoelectric sensor (e.g., reflective photoelectric switch) of each detection segment is aligned with the product surface. When the marking point passes by, the sensor outputs a pulse electrical signal to the control mechanism 130 due to the change in the intensity of reflected light (there is a color difference or reflectivity difference between the marking point and the product surface).

[0060] The control mechanism 130 records the pulse signal time difference (Δt) between two adjacent markers within the same detection segment. 实 ), and calculate the actual interval distance "L" by combining the actual product speed (v) at that moment. 实 =v×Δt 实 And compared with the theoretical interval L, the deviation value "ΔL=L" is obtained. 实 "-L" indicates the overall stability of extrusion line 110 based on the difference. Based on repeatability and overall data reliability, if the overall stretch (overall deviation value) from the forced shrinkage section to the winding section is ≤10mm and the difference between each section (deviation value between each section) is ≤5mm, then extrusion line 110 can be considered to be operating stably. Otherwise, it is considered that a production abnormality has occurred, and the corresponding abnormal equipment can be identified based on the source of the abnormal data.

[0061] As an embodiment of this application, the automatic stability detection device further includes a data processing terminal 140, which is electrically or signal-connected to the control mechanism 130. The data processing terminal 140 receives data transmitted by the control mechanism 130 and stores, analyzes, and displays the data. The data processing terminal 140 can be an industrial computer, capable of displaying the fixed length data (L) of each segment of the product in real time.

[0062] The working process of the automatic stability detection device for the 110 extrusion line of the 120 tire semi-finished product in this utility model is as follows:

[0063] Step 10: The automatic marking mechanism 4 is activated to automatically mark the products (tire semi-finished products 120) on the extrusion line 110;

[0064] Step 20: After the product passes through the receiving section (forced shrinkage device 2), the control mechanism 130 controls the inkjet printer to print marking dots on the surface of the product at preset intervals (e.g., 500mm).

[0065] Step 30: The light detection component 100 starts working, and the LED light shines on the product;

[0066] Step 40: The photoelectric sensor detects the change in light, converts the light signal into an electrical signal, and further transmits it to the control mechanism 130;

[0067] Step 50: The control mechanism 130 calculates the fixed length data of each segment and the deviation value between the received electrical signal time interval and the running speed of the linkage line.

[0068] In step 60, the control mechanism 130 transmits the data obtained in step 50 to the data processing terminal 140, displays the test results of each section of the tire semi-finished product 120 extrusion line 110, and judges whether there are any abnormalities in each section of the extrusion line 110.

[0069] It should be further explained that the control mechanism 130 has preset operating speed parameters for the product and theoretical interval distance between the marking points. When the product passes through the receiving section, the control mechanism 130 controls the automatic marking mechanism 4 to spray marking points on the product surface at set intervals. When the product runs to each section position, the light source in the light detection component 100 shines on the product. When the photoelectric sensor detects the marking point, it sends an electrical signal to the control mechanism 130.

[0070] For example, the preset interval of the marking points is one marking point printed every 500 mm, i.e., L=500 mm. Based on this theoretical data of marking point interval, the measured fixed length data of each stage of the extrusion line 110 are as follows. Figure 3 and attached Figure 4 .

[0071] According to the appendix Figure 3 The measurement results are normal, the linkage line shows no abnormal stretching, and the forced contraction to the pre-winding stretch is ≤5mm; (Attached) Figure 4 The measurement results show an abnormality, indicating abnormal stretching of the linkage line (blowing device 8 stretches 9mm > 5mm). Relevant management personnel can use this information to inspect and adjust the relevant equipment at this location.

[0072] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
