Description

Technical Field

[0001] The utility model relates to the technical field of cord fabric weaving, in particular to a cord fabric water circulation temperature control suction port device. Background Art

[0002] Cord fabric is a skeleton fabric for tires made of strong strands as warp and medium and fine single yarns as weft. The warp yarns are arranged closely and the weft yarns are arranged sparsely, resembling a cord. The warp yarns are also called cord yarns, which bear the load, and the weft yarns fix the position of the warp yarns, hence the name cord fabric. Cord fabric is used as the skeleton of rubber products such as tires, allowing them to withstand huge pressure, impact loads and strong vibrations.

[0003] Currently in the production process of cord fabric, the excess glue on the fabric surface after being dipped in glue needs to be sucked away by the negative pressure of the suction port and returned to the glue tank for recycling. The temperature changes affect the stability of production, especially in the extremely cold weather in winter. The suction port is prone to ice and blockage, causing the fabric surface to become sticky and spotted, affecting product quality. Utility Model Content

[0004] The utility model aims to provide a water circulation temperature control suction port device for cord fabric.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a shell, and a suction nozzle is connected to the outer wall of one side in the extension direction of the shell, and a suction port connected to the interior is opened on the outer wall of the suction nozzle. The bottom wall of the shell is connected to a reflux pipe of an external reflux system, and the outer side wall of the shell is connected to a negative pressure duct installed with an external negative pressure system. A hollow heating copper tube is arranged in the suction nozzle, and a water circulation heating device is externally arranged on the hollow heating copper tube. The hollow heating copper tube is folded back and forth in a U shape and buried in the shell.

[0007] By adopting the above technical scheme, when used in winter or in the north, a water channel is provided in the hollow heating copper tube, and the water circulation heating device can cyclically inject hot water into the hollow heating copper tube continuously to achieve the effect of quickly and efficiently heating the adsorption nozzle and the shell, which can effectively avoid the ice blockage at the suction port and the internal passage of the shell, and prevent the cloth surface from sticking or producing spots. At the same time, the contact area between the U-shaped reciprocating folded hollow heating copper tube and the shell and the adsorption nozzle is effectively increased, which can further improve the overall heat exchange rate. The hot water circulation heating method is used for the adsorption nozzle working close to the cloth, which has the advantages of safety and stability compared with electric heating.

[0008] Furthermore, the hollow heating copper tube passes through the outer wall of the adsorption nozzle and is fixedly provided with a water inlet pipe and a water outlet pipe. The water circulation heating device includes a water tank with a sufficient amount of aqueous solution inside. A circulation pump connected to the inside of the water tank is fixedly installed on the outer wall of the water tank. The water inlet pipe is connected to the circulation pump, and the water outlet pipe is connected to the water tank. A plurality of heating rods for an external power supply and a control system are vertically provided on the bottom wall of the water tank.

[0009] By adopting the above technical solution, when the equipment is working, the heating rod and the circulating pump are turned on at the same time. The heating rod can continuously heat the water in the water tank, and the circulating pump continuously pumps out the hot water in the water tank. The high-temperature water enters the hollow heating copper tube through the water inlet pipe, completes the heat exchange with the adsorption nozzle and the shell, and then cools down through the isomorphic water outlet pipe and flows back to the water tank. The adsorption nozzle and the shell are continuously and efficiently heated by the reciprocating cycle to ensure that they maintain a good working temperature to avoid ice blockage at the suction port and internal passages.

[0010] Furthermore, a water tank is provided on the top wall of the water tank, and the aqueous solution is stored in the water tank. A protective cover covering the water tank is hingedly provided on the outer wall of the water tank, and a buckle for locking the water tank is fixedly provided on the outer wall of the protective cover. A cotton porous filter is provided on the inner wall of the water tank, and a plurality of groups of limiting convex strips are extended from the inner wall of the water tank, and the limiting convex strips are arranged at intervals, and the cotton porous filter is arranged in an inlaid manner at the intervals of the limiting convex strips.

[0011] By adopting the above technical solution, the protective cover is combined with the buckle to effectively protect the internal structure of the water tank to prevent the invasion of foreign matter and impurities, while being easily opened for easy maintenance. The cotton porous filter that cuts off the inner wall of the water tank has a good adsorption effect. The aqueous solution must pass through the cotton porous filter during the circulation process, which can effectively adsorb impurities in the circulating water and ensure the long-term stable operation of the circulating water system. The cotton porous filter is embedded with the limiting convex strips and is locked at intervals. When it needs to be replaced, it can be pulled out from the locking position and reinserted into a new cotton porous filter.

[0012] Furthermore, a plurality of temperature sensors for external power supply and control system are fixedly arranged on the outer wall of the adsorption nozzle, and a temperature-sensitive color belt is arranged around the outer wall of the adsorption nozzle.

[0013] By adopting the above technical scheme, the temperature sensor combined with the control system can intelligently control the start and stop of the heating rod and the circulation pump. The temperature sensor converts the temperature information into an electrical signal for transmission to the control system. The control system can be a PLC or a single-chip microcomputer. When the temperature around the adsorption nozzle is too low and exceeds the low temperature threshold set by the control system, the control system starts the heating rod and the circulation pump for heating. After continuous heating, when the temperature around the adsorption nozzle is too high and exceeds the high temperature threshold set by the control system, the control system shuts down the heating rod and the circulation pump to stop heating, so that the adsorption nozzle and the shell are always kept in a good working temperature range. The temperature-sensitive color strip is drawn with waterproof temperature-sensitive paint, which can intuitively observe the temperature around the adsorption nozzle. If the water circulation heating device fails and causes the temperature of the adsorption nozzle to be abnormal, the color of the temperature-sensitive color strip can be clearly and intuitively understood by observing whether it is at the normal working temperature, which has a good auxiliary effect.

[0014] In summary, the beneficial technical effects of the utility model are:

[0015] 1. A U-shaped reciprocating folded hollow heating copper tube and a water circulation heating device are used. The contact area between the U-shaped reciprocating folded hollow heating copper tube and the shell and the adsorption nozzle is effectively increased. The adsorption nozzle close to the cloth is heated by hot water circulation, which effectively avoids ice blockage at the suction port and the internal passage of the shell;

[0016] 2. The cotton porous filter is used to effectively absorb impurities in the circulating water, ensuring the long-term stable operation of the circulating water system;

[0017] 3. Temperature sensors and temperature-sensitive ribbons are used to intelligently control the start and shut down of the heating rod and the circulation pump, so that the adsorption nozzle and the shell are always kept in a good working temperature range. BRIEF DESCRIPTION OF THE DRAWINGS
