Heating device for use in spray of tire leakproof glue

Abstract

The invention provides a heating device for use in the spray of tire leakproof glue. The heating device comprises a leakproof glue liquid tube; an oil delivery tube for heating is arranged beside theleakproof glue liquid tube; the outer surfaces of the leakproof glue liquid tube and the oil delivery tube are sleeved with an outer sleeve tube capable of forming a closed cavity, the back end of theouter sleeve tube is provided with an oil inlet and an oil outlet, and the oil inlet is directly connected with the back end of the oil delivery tube in the outer sleeve tube; and the oil outlet at the front end of the oil delivery tube is arranged in the closed cavity of the outer sleeve tube on the side of a threading connector of a nozzle of the leakproof glue liquid tube. With a built-in oildelivery tube, the heating device has skillful design and compact structure, lowers energy consumption, improves heating efficiency, greatly reduces the volume of a heater, avoids the collision scratch between the heater and the inner edge of the rotating tire, and improves the safety of production personnel and equipment. When the heater works, the oil delivery tube for filling oil in the cavityis always immersed in the flowing high-temperature oil, so the constant temperature of the high-temperature oil, namely the process temperature of the leakproof liquid, is ensured.

Description

【Technical field】 [0001] The invention belongs to a heater, in particular to a heater used when tires are coated with anti-leakage glue. 【Background technique】 [0002] In the equipment for producing anti-leakage tires by coating the inner wall of tires with anti-leak tape layer, the oil delivery pipe used for heating in the original heating device for spraying tire anti-leak adhesive adopts an external method, that is, the oil inlet is designed in the On the casing at the front end of the heating device, the oil outlet is designed on the casing at the rear of the heating device. This structure increases the volume of the parts because the oil inlet and the oil delivery pipe are installed outside the casing near the nozzle. Large, when processing tires, they often scrape against the inner edge of the tire, causing damage to other parts, thus affecting the coating effect of the leak-proof glue, and the energy consumption is large, and the heating efficiency is low. 【Content...
