Description

Technical Field

[0001] The utility model relates to the field of tire vulcanizing equipment, in particular to a device for automatically spraying and sweeping an upper mold of a tire vulcanizing machine. Background Art

[0002] As we all know, the process of tire vulcanization is to place the raw tire in a heated mold, and the inside of the mold is filled with a vulcanizing medium by a capsule installed in the central mechanism to provide pressure and heat. In order to prevent the finished vulcanized tire from sticking to the upper mold, and the tire cannot stay in the lower mold normally after the mold is opened for automatic unloading, it is necessary to spray a release agent on the upper mold. Among them, the pattern block area of ​​the upper mold requires a larger amount of spraying, and the more complex the pattern, the larger the amount of spraying.

[0003] At present, the automatic release agent spraying device commonly used by various tire manufacturers has a nozzle that runs to the central axis below the upper mold, and the spray angle is scattered upward to spray the release agent to the relevant parts. Due to the long distance and the oblique spray angle, it is difficult to spray the release agent evenly to each part of the pattern block. For molds with complex patterns such as snow tires, manual spraying is often required. This manual spraying requires frequent interruption of continuous automatic production of tires. After the shutdown, the spraying is carried out manually, which not only affects production efficiency, but also increases the workload of operators. Due to the high temperature of the relevant parts of the tire vulcanizer, there are safety hazards. On the other hand, the above-mentioned spraying, whether automatic or manual, does not have the function of blowing and drying. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a device for automatically spraying the upper mold of a tire vulcanizer, which solves the problem that manual spraying of capsules requires interrupting the continuous automatic production of tires, which not only affects production efficiency, but also increases the workload of operators and poses safety hazards to operations.

[0005] The utility model adopts the following technical solution to solve the technical problem: a device for automatically spraying and sweeping the upper mold of a tire vulcanizer, which is provided with a base, on which an upper mold, a lower mold and a main machine column are arranged, and the upper mold can be lifted and lowered along the main machine column. The utility model is characterized in that a spraying and sweeping column is vertically installed at the left rear of the base, a swing arm is installed on the spraying and sweeping column via a lifting and swinging driving device, a sprayer is arranged at the end of the swing arm, and the sprayer consists of a rotary arm, a rotating driving device, a horizontal nozzle and an angled nozzle, the rotating driving device is installed at the end of the swing arm, the rotary arm is installed at the end of the rotating shaft of the rotating driving device, the horizontal nozzle and the angled nozzle are installed at the end of the rotary arm, and are respectively connected with a release agent hose and a compressed air hose.

[0006] The beneficial effect of the utility model is that the relevant parts of the upper mold are sprayed forward at a close distance, which is a good substitute for manual spraying, and the mold is purged with compressed air to ensure the cleanliness of the mold and thus the appearance quality of the tire, thereby achieving the purpose of improving efficiency and safety and reducing workload, and it is possible to choose to spray the relevant parts of the upper mold separately, spray and blow dry, or blow away the debris on the upper mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] In the figure, the utility model is provided with a base 1, on which an upper mold 4, a lower mold 2 and a main machine column 3 are arranged, the upper mold 4 can be raised and lowered along the main machine column 3, a spray column 5 is vertically installed at the left rear of the base 1, a swing arm 6 is installed on the spray column 5 through a lifting and swinging driving device, the swing arm 6 can be raised and lowered along the spray column 5, and reciprocate with it as an axis. A sprayer 7 is arranged at the end of the swing arm 6, and the sprayer 7 is composed of a rotary arm 72, a rotary driving device 71, a horizontal nozzle 73, and an angle nozzle 74, the rotary driving device 71 is installed at the end of the swing arm 6, the rotary arm 72 is installed at the end of the rotating shaft of the rotary driving device 71, the horizontal nozzle 73 and the angle nozzle 74 are installed at the end of the rotary arm 72, and are respectively connected to a mold release agent hose and a compressed air hose.

[0012] During the automatic production process of the vulcanizer, once it is necessary to spray the release agent or blow the upper mold 4, the upper mold 4 is lowered to a certain height. The lowered height in this embodiment is the automatic loading height. The sprayer 7 is lowered to the transfer height below the upper mold 4, and the swing arm 6 is swung in from the left rear of the vulcanizer to make the rotary drive device 71 of the sprayer 7 coincide with the center line of the upper mold 4; the swing arm 6 rises, so that the rotary arm 72 of the sprayer 7 is raised to the horizontal center line height of the upper mold 4. The rotary arm 72 rotates circumferentially with the rotating shaft of the rotary drive device 71 as the center under the drive of the rotary drive device 71. At the same time, the horizontal nozzle 73 and the angled nozzle 74 spray compressed air on the relevant parts of the upper mold 4 separately or simultaneously as needed to blow or spray the release agent. The release agent sprayed to the mold is connected end to end as a circle. The rotary arm 72 rotates in the opposite direction to return to its original position. According to the setting of the control program, multiple circles of operation can be performed. After the operation is completed, the sprayer 7 is lowered, swung out, and raised to Figure 1 In the position shown, the vulcanizing press continues to load and produce.

[0013] The horizontal nozzle and the angled nozzle can be used separately or simultaneously to spray or purge the relevant parts of the upper mold at a close distance, or to blow dry the liquid sprayed on the mold during the spraying process. Preferably, the release agent sprayed on the mold can be blown dry during the spraying to prevent it from flowing or dripping.
