Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cord fabric production, specifically to a glue tank double liquid level alarm system. BACKGROUND

[0002] Cord fabric impregnation is a process that combines fabric with resin or adhesive, commonly used to produce cord fabric with specific properties or functions, such as cord or covering materials used in automotive, construction, industrial, and other fields. This process can enhance the strength, durability, and water resistance of the cord fabric.

[0003] Currently, a weighing type liquid level detection system is commonly used in the production process of cord fabric. However, this system uses four pressure sensors on a lifting platform to detect the liquid level. The existing shear support type lifting platform is prone to tilting during lifting, which can cause the sensor detection to fail, resulting in inaccurate detection. Once the detection is inaccurate, the liquid level of the glue tank will be out of control, and the fabric cannot be immersed in the glue solution, which poses a risk to product quality.

[0004] In addition, during the production of cord fabric, the liquid level of the glue tank is prone to fluctuation, and rubber can accumulate on the edge of the glue tank. After the liquid level fluctuates, the rubber on the original edge of the liquid surface can be brought into the glue solution in the glue tank, thereby sticking to the fabric and causing the product quality to decrease. The glue tank is filled from the top, and the fabric continuously consumes the glue solution at the top of the glue tank, causing the glue solution at the bottom of the glue tank to deposit and stagnate, resulting in uneven distribution of the glue solution at the top and bottom, which affects product quality. SUMMARY

[0005] The utility model aims to provide a glue tank double liquid level alarm system.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] The utility model discloses a glue tank double liquid level alarm system, which comprises a glue tank body provided with a notch in the top wall, a shearing telescopic device fixedly installed on the bottom wall of the glue tank body, a plurality of supporting rollers arranged at intervals above the glue tank body, wherein the supporting rollers are positioned and rotatably arranged, a curtain fabric is arranged on the outer wall of the supporting roller and vertically inserted into the notch, an overflow port is formed through the outer wall of the top wall of the glue tank body and communicates with the notch, a temporary storage bin is fixedly arranged around the outer wall of the bottom wall of the glue tank body, a circulating pump is fixedly arranged on the outer wall of the temporary storage bin and communicates with the notch, a backflow port is formed through the outer wall of the temporary storage bin and communicates with the circulating pump, the backflow port is arranged close to the bottom of the notch, and a filter screen is fixedly installed in the temporary storage bin and separates the temporary storage bin.

[0008] By adopting the technical scheme, when working, the carrier roller rotates to drive the canvas to advance and enter the dipping tank body in turn for dipping. When the glue solution in the slot fluctuates or is too much, the excess glue solution flows out directly from the overflow port, and the rubber on the edge of the liquid surface floats on the surface of the liquid due to the light weight after dehydration, and flows out from the overflow port with the glue solution, thereby achieving the effect of keeping the glue solution clean. The overflowed glue solution is collected in the temporary storage bin. When the height of the glue solution in the slot is lower than the set threshold, the circulating pump is started to supplement the glue solution in the slot. The filter screen is arranged to filter out the rubber and other hard impurities in the glue solution when the glue solution passes through. Meanwhile, the backflow port is close to the bottom of the slot, so that the glue solution in the slot is always kept highly clean and the overall glue solution is more uniform, thereby ensuring the quality of dipping.

[0009] Further, the slot inner wall is attached with an overflow baffle above the overflow port, and the overflow baffle is arranged to be inclined upward and inward.

[0010] By adopting the technical scheme, the arrangement of the overflow baffle can further block the liquid surface. When the liquid surface fluctuates too violently to be discharged from the overflow port in time, the overflow baffle can well block the fluctuating glue solution to prevent the glue solution from splashing out of the slot and causing waste, thereby having a good wave stabilizing effect.

[0011] Further, an ultrasonic liquid level meter is fixed above the top wall of the dipping tank body and aligned with the slot, and a weighing liquid level sensor is fixedly installed at the four corners of the dipping tank body. The ultrasonic liquid level meter and the weighing liquid level sensor are externally connected with an audible and visual alarm.

[0012] By adopting the technical scheme, the ultrasonic liquid level meter and the weighing liquid level sensor are double cooperated. When the dipping tank body is out of balance and the pressure values at the four corners of the weighing liquid level sensor are greatly different, and the liquid level of the glue solution exceeds the process control range, the ultrasonic liquid level meter and the weighing liquid level sensor detect and judge at the same time, and send an electric signal to the audible and visual alarm when confirming that the liquid surface state is not up to standard, so that the audible and visual alarm gives an audible and visual alarm to remind the on-site staff, thereby realizing a double error prevention effect.

[0013] Further, the temporary storage bin is a transparent shell, a plurality of scale lines are arranged on the outer wall of the temporary storage bin and are equally divided, and the scale lines are arranged around the outer wall of the bin body of the temporary storage bin.

[0014] By adopting the technical scheme, the temporary storage bin is arranged around the dipping tank body, the weight distribution is more uniform, and the overall state of the dipping tank body can be effectively avoided from being affected by the self-weight of the temporary storage bin and the overflowed glue solution. Meanwhile, the transparent shell combined with the scale lines has a good marking effect, and when the dipping tank body deviates, the deviation direction and the deviation degree can be intuitively displayed.

[0015] Further, the shearing and telescoping device comprises a folding frame hingedly folded in a z-shape from head to tail, the folding frames are arranged in pairs, a glue tank seat is fixedly connected to the upper end of the folding frame, the glue tank body is fixedly installed on the top wall of the glue tank seat, a base is fixedly connected to the lower end of the folding frame, the folding frame comprises a positioning frame and a sliding frame, the positioning frame is slidingly connected to the upper end of the glue tank seat, the lower end of the positioning frame is hingedly connected to the base, the sliding frame is hingedly connected to the upper end of the base, and the lower end of the sliding frame is slidingly connected to the base, a drive motor for driving the sliding frame to slide is fixedly arranged on the top wall of the base, a sliding plate is threadedly connected to the rotating shaft of the drive motor and arranged on the top wall of the base, the sliding plate is fixedly connected to the lower end of the sliding frame, a buffer tube is arranged between the glue tank seat and the base, the buffer tube comprises a positioning tube and an extension rod, the positioning tube is provided with a buffer cavity for slidingly connecting the extension rod, and the outer wall of the buffer tube is provided with buffer micro-holes communicating with the buffer cavity, and the extension rod is sealingly embedded in the buffer cavity.

[0016] By adopting the above technical scheme, the roller, the drive motor, the ultrasonic liquid level meter, the weighing liquid level sensor and the audible and visual alarm can be connected to the PLC control system and externally connected to the power supply, so that the intelligent control equipment operation effect is achieved, when the drive motor rotates, the sliding plate is pushed to reciprocatingly slide along the top wall of the base through the threaded cooperation, the sliding of the sliding plate drives the sliding frames at both ends to slide, when the sliding frames slide, the folding frame as a whole will be telescoped, so that the effect of controlling the height of the glue tank body is achieved, the buffer tube has good buffering effect, there is sufficient air in the buffer tube, when the extension rod moves, the air in the buffer tube will enter and exit from the buffer micro-holes, because the buffer micro-holes are small, when the shearing and telescoping device fails or suddenly and rapidly rises due to other reasons, the air in the buffer micro-holes cannot be quickly discharged or sucked in within a short time, which can effectively inhibit the rapid sliding of the extension rod.

[0017] In summary, the beneficial technical effects of the utility model are as follows:

[0018] 1. The overflow port, temporary storage bin, circulating pump, backflow port and filter screen are adopted, so that the cleanliness of the glue liquid is always maintained to ensure the glue dipping quality;

[0019] 2. The ultrasonic liquid level meter, weighing liquid level sensor and audible and visual alarm are adopted, so that the ultrasonic liquid level meter and the weighing liquid level sensor are double cooperated to remind the on-site staff, thereby realizing the double error prevention effect;

[0020] 3. The transparent shell and scale line are adopted, which can intuitively display the offset direction and offset degree, thereby achieving good identification effect. BRIEF DESCRIPTION OF DRAWINGS
