Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, specifically a quality inspection device for the production of rubber-coated narrow V-belts. Background Technology

[0002] In the production of rubber-coated narrow V-belts, surface flatness, tensile strength, and surface defects (such as scratches, missing rubber, and bubbles) are key indicators affecting product quality and service life, and must be strictly controlled through quality inspection. Currently, the industry's quality inspection of rubber-coated narrow V-belts mostly adopts a combination of manual inspection and single-equipment inspection: surface flatness inspection relies on manual visual inspection or simple measuring tools, which is not only inefficient (difficult to adapt to the high-speed inspection requirements of the production line), but also greatly affected by human subjective judgment, and is prone to missing even tiny protrusions and dents; tensile strength testing requires transferring the rubber belt to a dedicated tensile equipment, which can easily cause secondary damage to the rubber belt due to the transfer operation, and the inspection process is scattered, increasing time and labor costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a quality inspection device for the production of narrow V-belts in rubber assembly, which has the advantage of high-precision detection of surface defects in rubber belts and solves the problem of existing equipment easily missing the detection of minute curves.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A quality inspection device for the production of rubber band narrow V-belts includes a base, on which a transmission mechanism for driving the rubber belt is provided, and a detection mechanism for detecting the surface flatness of the rubber belt is also provided.

[0006] The detection mechanism includes a bracket fixed to a base, a support bar fixed to the bracket, a slide rod slidably connected to the support bar, a pressure strip that fits against the surface of a rubber strip fixed to the bottom end of the slide rod, a transmission disc fitted on the slide rod, a spring fixed between the transmission disc and the support bar, a stylus fixed to the top of the slide rod, and a touch panel corresponding to the stylus installed on the support bar.

[0007] Preferably, the transmission mechanism includes a motor one fixedly mounted on the base, a screw fixedly connected to the output end of the motor one, a transmission block threadedly connected to the screw, the transmission block being slidably connected to the base through a sliding groove, a support base fixedly mounted on the transmission block, a motor two fixedly mounted on the support base, a drive wheel fixedly connected to the output end of the motor two, a driven wheel rotatably mounted on the side of the base away from the drive wheel via a load-bearing frame, and a rubber belt sleeved between the drive wheel and the driven wheel.

[0008] Preferably, a touch switch is fixedly mounted on the bracket, and the touch switch is located below the pressure strip.

[0009] Preferably, a visual inspection camera is also installed on the bracket, and a display screen is fixed on the base.

[0010] Preferably, an elastic buffer layer is fixed to the side of the pressure strip facing the rubber belt, and the elastic buffer layer is made of silicone rubber.

[0011] Preferably, a data storage module is fixedly connected to the base. The data storage module is electrically connected to the touch panel and is communicatively connected to the display screen via a wire. It is used to store the surface flatness data of the rubber strip detected by the touch panel in real time.

[0012] By means of the above technical solution, this utility model provides a quality inspection device for the production of rubber-coated narrow V-belts, which has at least the following beneficial effects:

[0013] 1. This quality inspection device for producing narrow V-belts in rubber bands, by setting up a detection mechanism, can ensure that the pressure strip always fits against the surface of the rubber belt, converting surface protrusions or depressions into displacement signals of a stylus, thereby achieving automated and accurate detection of the flatness of the rubber belt surface, replacing manual visual inspection, and greatly improving detection accuracy and efficiency.

This quality inspection device for producing narrow V-belts with rubber bands, through the setting of a transmission mechanism, can drive the drive wheel to move and realize the automatic unfolding and tensioning of the rubber belt. In conjunction with the second motor to drive the rubber belt transmission to complete surface inspection, it can also perform tensile strength testing on the rubber belt by continuously moving the drive wheel outward, realizing the integration of "surface inspection + tensile testing" and reducing equipment investment costs.

[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] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a quality inspection device for the production of rubber-coated narrow V-belts.

[0026] Example 1:

[0027] Combination Figures 1-3 As shown, the present invention provides a quality inspection device for the production of rubber band narrow V-belts, including a base 100. The base 100 is provided with a transmission mechanism 200 for driving the rubber belt transmission and a detection mechanism 300 for detecting the surface flatness of the rubber belt. It eliminates the need for additional transfer of the rubber belt, which reduces manual intervention in the detection process, avoids secondary damage to the rubber belt caused by transfer, shortens the time of the quality inspection process, and improves the overall quality inspection efficiency. At the same time, the base 100 provides stable support for each component, ensuring the stability of the transmission and detection process and reducing detection errors caused by equipment shaking.

[0028] The testing mechanism 300 includes a bracket 301 fixed to a base 100, a support bar 303 fixed to the bracket 301, a slide rod 304 slidably connected to the support bar 303, a pressure strip 305 fixed to the bottom end of the slide rod 304 and conforming to the surface of the rubber belt, a transmission disc 306 mounted on the slide rod 304, a spring 307 fixed between the transmission disc 306 and the support bar 303, a stylus 308 fixed to the top of the slide rod 304, and a touch panel 309 corresponding to the stylus 308 mounted on the support bar 303. During the operation of the rubber belt, the spring 307 pushes the transmission disc 306 downward, and the slide rod 304... As the transmission disc 306 moves, the pressure strip 305 on the slide bar 304 comes into contact with the surface of the rubber belt. When there are protrusions and depressions on the surface of the rubber belt during transmission, the slide bar 304 will move up or down. The stylus 308 moves with the slide bar 304 and moves on the stylus 308, thereby indirectly detecting the surface condition of the rubber belt. The physical differences in the surface morphology of the rubber belt are converted into identifiable displacement signals, achieving accurate detection of surface flatness. Compared with manual visual inspection, it can not only capture minute defects, but also avoid subjective judgment errors and improve detection accuracy.

[0029] Specifically, a touch switch 310 is fixedly mounted on the bracket 301. The touch switch 310 is located below the pressure bar 305. When the rubber belt breaks due to excessive fatigue during transmission, the pressure bar 305 descends and contacts the touch switch 310, shutting off the second motor 207. The second motor 207 is shut off immediately through the switch signal, preventing the broken rubber belt from continuing to transmit disorderly under the drive wheel 205. This prevents the broken rubber belt from wrapping around equipment parts and causing mechanical damage, extending the service life of the equipment. It also prevents the broken end from splashing and causing safety hazards, improving operational safety. There is no need for real-time manual monitoring of the breakage, reducing the pressure of manual on-duty personnel.

[0030] Furthermore, a visual inspection camera 302 is also installed on the bracket 301, and a display screen 101 is fixed on the base 100. The visual inspection camera 302 can acquire real-time images of the rubber belt surface and capture surface defects other than flatness (such as scratches, missing glue, bubbles, uneven color, etc.), complementing the flatness detection to achieve full-dimensional detection of the rubber belt surface quality. The display screen 101 can simultaneously display the real-time images captured by the camera and the detection data, which makes it convenient for staff to observe the surface condition of the rubber belt intuitively without having to get close to the equipment, improving the convenience of operation. At the same time, it is convenient for multiple people to view the detection results at the same time, which is conducive to quality judgment and problem analysis. If a defect is found, the detection can be paused immediately to find the root cause of the problem in time.

[0031] An elastic buffer layer is fixed to the side of the pressure strip 305 facing the rubber belt. The elastic buffer layer is made of silicone rubber, which has good elasticity and wear resistance.

[0032] A data storage module is fixedly connected to the base 100. The data storage module is electrically connected to the touch panel 309 and is also communicatively connected to the display screen 101 via a wire. It is used to store the surface flatness data of the rubber strip detected by the touch panel 309 in real time.

[0033] As can be seen from the embodiment, the data storage module can store the flatness detection data transmitted by the touch panel 309 in real time, realizing the traceability of the detection data and facilitating subsequent querying of the detection records of a certain batch or a certain rubber belt. This provides data support for quality analysis and product traceability. When quality problems occur, anomalies in the production process can be investigated through historical data. At the same time, the data storage module is linked with the display screen 101, which can synchronize the stored data to the display screen 101 in real time. Staff can intuitively view the data change trend and quickly judge the overall condition of the rubber belt surface flatness without manual data recording, reducing the workload and recording errors of manual recording, improving data management efficiency, and providing data basis for subsequent production process optimization.

[0034] Example 2:

[0035] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, the transmission mechanism 200 includes a motor 201 fixedly mounted on the base 100. A screw 202 is fixedly connected to the output end of the motor 201. A transmission block 203 is threadedly connected to the screw 202. The transmission block 203 is slidably connected to the base 100 via a sliding groove. A support 204 is fixedly connected to the transmission block 203. A motor 207 is fixedly mounted on the support 204. A drive wheel 205 is fixedly connected to the output end of the motor 207. A driven wheel 206 is rotatably mounted on the side of the base 100 away from the drive wheel 205 via a load-bearing frame. A rubber belt is sleeved between the drive wheel 205 and the driven wheel 206. First, the rubber belt is sleeved between the drive wheel 205 and the driven wheel 206, then the motor 201 starts driving the screw 202. 2. Rotation of screw 202 drives the support seat 204 on transmission block 203 to move. Drive wheel 205 moves outward with support seat 204, causing the rubber belt to unfold. Then, motor 207 starts to drive drive wheel 205 to rotate, which can then drive the rubber belt for transmission. Alternatively, support seat 204 continues to move, continuously pulling the rubber belt through drive wheel 205, thereby enabling tensile strength testing of the rubber belt. Motor 207 driving drive wheel 205 to rotate can drive the rubber belt to transmit smoothly for surface inspection, while motor 1 201 continuously drives drive wheel 205 to move outward, which can apply a controllable tensile force to the rubber belt to complete the tensile strength test. No additional dedicated tensile testing equipment is required, which simplifies the testing process and reduces equipment costs.

[0036] As can be seen from the above embodiments: First, the narrow V-belt of the rubber band to be tested is smoothly fitted between the driving wheel 205 and the driven wheel 206. Then, motor 1 201 is started, which drives the screw 202 to rotate, causing the transmission block 203 to slide along the slide groove and drive the support seat 204, motor 207, and driving wheel 205 to move away from the driven wheel 206 until the rubber belt is fully unfolded and tensioned. Then, motor 1 201 is turned off, and then motor 207 is started. The driving wheel 205 rotates, driving the rubber belt and driven wheel 206 to transmit power. At this time, the spring 307 of the detection mechanism 300 pushes the transmission disc 306 and the slide bar 304 to move down, allowing the silicone rubber elastic buffer layer of the pressure strip 305 to contact the... The rubber belt surface is tightly fitted. When there are protrusions or depressions on the surface of the rubber belt during transmission, the pressure bar 305 will drive the slide bar 304 and the stylus 308 to move up and down. The touch panel 309 converts the displacement signal into an electrical signal and transmits it to the data storage module for real-time storage. At the same time, the data is transmitted to the display screen 101 for real-time display via wires. During the rubber belt transmission test, if the rubber belt breaks due to fatigue, the pressure bar 305 will lose support and move down to contact the touch switch 310, triggering the switch to control the motor 207 to shut down to avoid equipment damage. At the same time, the visual inspection camera 302 is activated to take real-time pictures of the rubber belt surface, and the image is transmitted to the display screen 101, allowing the operator to observe whether there are scratches, missing glue, or other defects. If tensile strength needs to be tested, after the rubber belt is unfolded, the motor 201 is activated again, allowing the drive wheel 205 to continuously pull the rubber belt away from the driven wheel 206 to apply tensile force until the rubber belt breaks or reaches a preset degree. The operator records the tensile strength information. After the test is completed, turn off motor 207 and the camera, start motor 1 201 in reverse so that the drive wheel 205 is close to the driven wheel 206 to loosen the rubber belt, and then remove the rubber belt after the test.
