Description

Technical Field

[0001] The utility model relates to the technical field of gluing machines, in particular to an anti-blocking gluing machine. Background Art

[0002] The brake band is the main structure of the band brake. The rotating wheel or other rotating parts are clamped by controlling the brake band, so as to use the friction generated by the brake band to brake. During the production process of the brake band, the surface of the mesh cloth needs to be glued by a gluing machine. When some gluing machines are used, the mesh cloth of the brake band is firstly horizontally conveyed by a conveying device, and then the colloid is controlled by the pressure driving element to flow out along the pipeline through the glue nozzle, and the colloid falls to the surface of the mesh cloth, so as to glue the surface of the brake band mesh cloth. After the mesh cloth is glued, the control valve on the pipeline is closed to stop the flow of colloid in the glue nozzle. However, after the brake band mesh cloth is glued, colloid gathers at the outer edge of the glue nozzle. The colloid will gradually solidify after long-term contact with the external environment. With the increase of the number of uses, the solidified colloid at the glue nozzle will gradually increase, which is easy to cause blockage of the glue nozzle, which needs to be improved.

[0011] Furthermore, a spiral metal heating tube is provided in the wall of the gluing nozzle, and the input end of the spiral metal heating tube is electrically connected to the output end of the single-chip microcomputer to heat the colloid inside the gluing nozzle to prevent it from solidifying.

The anti-blocking mechanism 9 includes a cross 91, a telescopic column 92, a spring 93, a blocking seat 94 and a conical ring 95. The cross 91 is arranged inside the upper glue nozzle 8, and the lower side of the cross 91 is provided with a blocking seat 94 through a telescopic column 92 and a spring 93. The spring 93 is movably connected to the outer end of the adjacent telescopic column 92. The inner wall of the upper glue nozzle 8 is provided with evenly distributed sliding grooves, and a conical ring 95 is slidably connected between two adjacent sliding grooves. The blocking seat 94 is installed in cooperation with the conical ring 95, and the anti-blocking mechanism 9 also includes a telescopic column 96 and a spring Spring 2 97, telescopic column 2 96 and spring 2 97 are all arranged between the slide groove and the adjacent conical ring 95, spring 2 97 is movably sleeved with the outer end of the adjacent telescopic column 2 96, spiral metal heating tube 10 is arranged in the wall of glue nozzle 8, the input end of spiral metal heating tube 10 is electrically connected with the output end of single chip computer 2, the lower end of glue nozzle 8 is connected in series with solenoid valve 2 11, the input end of solenoid valve 2 11 is electrically connected with the output end of single chip computer 2, spring 1 93 is initially in a stretched state, spring 2 97 is always in a compressed state, and the stretching elastic force of spring 1 93 is much greater than the compressing elastic force of spring 2 97, when the mesh cloth of brake belt is glued, single chip computer 2 opens solenoid valve 1 6 and solenoid valve 2 11 to release the glue delivery pipe 5 respectively The first and second springs 93 and 94 are in a closed position, and the ... After the rubber is applied to the brake belt, the rubber is pulled back and the rubber is pulled back to the bottom of the rubber nozzle 8. The rubber is then pulled back and the rubber is pulled back to the bottom of the rubber nozzle 8. The rubber is then pulled back and the rubber is pulled back to the bottom of the rubber nozzle 8.Therefore, the pressure difference is used to make the colloid at the bottom and the outer end of the bottom of the gluing nozzle 8 flow back to the inner bottom of the gluing nozzle 8, so as to avoid the colloid aggregation and solidification blockage at the mouth of the gluing nozzle 8, which is convenient to use. Then the single chip computer 2 closes the electromagnetic valve 11 to seal the bottom of the gluing nozzle 8, and at the same time, the single chip computer 2 starts the spiral metal heating tube 10 to heat the colloid in the gluing nozzle 8 to avoid solidification. After the brake band mesh cloth is glued, the anti-blocking gluing machine uses the spring elastic force through negative pressure to make the colloid under the gluing nozzle 8 flow back to the inside of the glue nozzle, and heats the colloid in the glue nozzle, effectively avoiding the colloid solidification and blockage at the glue nozzle, which is convenient to use.

[0025] Among them: it also includes a single chip microcomputer 2, which is arranged on the right side of the upper glue shell 1, the input end of the single chip microcomputer 2 is electrically connected to the external power supply, and the output end of the single chip microcomputer 2 is electrically connected to the input end of the glue supply pump 7, which is convenient for controlling electrical components.

[0026] The working principle of the anti-blocking gluing machine provided by the utility model is as follows: the spring 1 93 is initially in a stretched state, the spring 2 97 is always in a compressed state, and the stretching elastic force of the spring 1 93 is much greater than the compressing elastic force of the spring 2 97. When the mesh cloth of the brake belt is glued, the mesh cloth is first neatly placed on the upper side of the conveyor 12, and then the single-chip microcomputer 2 starts the conveyor 12 to make it use the belt to glue the mesh cloth, and then the single-chip microcomputer 2 opens the solenoid valve 1 6 and the solenoid valve 2 11 to respectively release the closed limit of the glue delivery pipe 5 and the glue nozzle 8, and then the single-chip microcomputer 2 starts the glue supply pump 7, and the glue supply pump 7 is operated to transport the colloid in the glue storage box 4 to the glue nozzle 8. The spring 2 97 is initially in a compressed state. When the colloid pressure in the glue nozzle 8 reaches a certain level, it is limited by the initial stretching elastic force of the spring 1 93. The blocking seat 91 and the conical ring 95 are compressed and move vertically downward at the same time. The telescopic end of the telescopic column 1 92 and the spring 1 93 continue to stretch, and the telescopic end of the telescopic column 2 96 extends. The spring 2 97 elastically resets. When the conical ring 95 slides to the bottom of the slide groove, as the colloid pressure in the glue nozzle 8 continues to increase, the conical ring 95 is limited by the slide groove and no longer moves downward. The blocking seat 94 continues to move downward to The adjacent conical rings 95 are separated, and the spring 1 93 continues to stretch elastically. Then, the colloid in the gluing nozzle 8 passes through the middle groove of the conical ring 95 and falls to the upper side of the mesh cloth through the bottom of the gluing nozzle 8, thereby performing a gluing operation on the mesh cloth surface of the brake band. The compressed elastic force of the spring 2 97 ensures that the conical ring 95 is always located at the lower end of the slide groove when the brake band mesh cloth is glued, so as to prevent the conical ring 95 from moving vertically upward along the slide groove during the gluing process of the brake band mesh cloth. When the brake band mesh cloth is glued, the single chip computer 2 closes the solenoid valve 1 6, and then the tensile elastic force of the spring 1 97 causes the blocking seat 94 to move up and back. During the upward movement of the blocking seat 94, the conical ring 95 is driven to move upward synchronously along the slide groove through the conical surface. At this time, the space above the colloid below the blocking seat 94 in the glue nozzle 8 becomes larger, and the air pressure is reduced. The pressure difference is used to make the colloid at the bottom of the glue nozzle 8 and the outer end of the bottom flow back to the inner bottom of the glue nozzle 8, thereby avoiding the colloid aggregation, solidification and blockage at the mouth of the glue nozzle 8. It is easy to use. Then the single-chip microcomputer 2 closes the solenoid valve 11 to seal the bottom of the glue nozzle 8. At the same time, the single-chip microcomputer 2 starts the spiral metal heating tube 10 to heat the colloid in the glue nozzle 8 to avoid its solidification.
