The driving gear 502 is meshed with a driven gear 503. The driven gear 503 is fixedly connected to a blocking ball 505 through a rotating rod 504. The blocking ball 505 is arranged at the bottom position of the inner cavity of the dispensing tube 3. The blocking ball 505 is provided with a diversion hole 506. By setting the blocking ball 505 at the bottom end position of the inner cavity of the dispensing tube 3 and providing the diversion hole 506 on the blocking ball 505, whether the dispensing liquid can pass through the diversion hole 506 is controlled by the rotation of the blocking ball 505, so as to prevent the overflow of the dispensing liquid. Compared with the prior art, it does not require continuous operation of electrical appliances, reduces power consumption, and the structure is relatively simple.
[0035] Specifically, the conveying platform 2 includes a second-stage motor 201. The second-stage motor 201 is connected to a driving roller 202 through a motor shaft. The driving roller 202 is connected to a driven roller 204 through a conveyor belt 203.
[0036] Further, the conveyor belt 203 is provided with equidistantly arranged placement grooves 205. The positions of the placement grooves 205 are vertically corresponding to the position of the dispensing tube 3.
[0037] Still further, an arc-shaped section 301 matching the blocking ball 505 is provided at the bottom end position of the dispensing tube 3. The blocking ball 505 abuts against the inner wall of the arc-shaped section 301. The bottom of the arc-shaped section 301 is connected to a glue outlet 302.
[0038] It should be noted that the rubber strip conveying assembly 6 includes a fixed housing 601. The fixed housing 601 fixedly connects the dispensing tube 3 and the connecting block 8. There are two correspondingly arranged conveying wheels 602 in the fixed housing 601. One end of the conveying wheel 602 is connected with a gear 603 through a rotating rod. The gears 603 are meshed with each other. One of the gears 603 is connected with a three-stage motor 604 through a motor shaft. The motor is used to drive the two conveying wheels 602 to convey the rubber strip. Compared with the spring structure in the prior art, it is easier to control the conveying speed of the rubber strip and the conveying is more stable.
[0039] It should be noted that a through hole 11 matching the rubber strip is provided at the top of the fixed housing 601, and the position structure of the conveying wheel 602 matches the rubber strip.
[0040] It is worth introducing that the fixed housing 601 is fixedly connected with a fixing bracket 12 corresponding to the three-stage motor 604, and the three-stage motor 604 is installed on the fixing bracket 12.
[0041] It should be emphasized that a protective housing 13 is fixedly connected to one side of the dispensing tube 3. The driving gear 502 and the driven gear 503 are arranged in the protective housing 13, and the first-stage motor 501 is installed on the protective housing 13.
[0042] Among them, the second-stage motor 201, the heater 4, the first-stage motor 501, the three-stage motor 604, and the electric push rod 9 are prior arts and will not be elaborated here. At the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.
[0043] Working principle and process: The rubber strip is wound around the rubber strip turntable 7. One end of the rubber strip passes through the through hole 11, passes between the two conveying wheels 602, and then extends into the dispensing tube 3. The three-stage motor 604 of the rubber strip conveying assembly 6 is started. Then, the two gears 603 rotate relative to each other, and then the two conveying wheels 602 rotate relative to each other, so as to convey the rubber strip into the dispensing tube 3. At the same time, the heater 4 is started to heat the rubber strip in the dispensing tube 3 to melt it into a liquid and store it in the dispensing tube 3. The high-frequency transformer is placed in the placement groove 205 on the conveying platform 2. The secondary motor 201 of the conveying platform 2 is started. Then, the driving roller 202 drives the conveyor belt 203 to rotate through the driven roller 204, so as to convey the high-frequency transformer to the lower part of the dispensing tube 3. At this time, the conveying platform 2 pauses operation. The electric push rod 9 is started. The electric push rod 9 extends to make the dispensing tube 3 close to the dispensing position on the high-frequency transformer. The primary motor 501 of the dispensing liquid anti-overflow assembly 5 is started. Then, the driving gear 502 drives the driven gear 503 to rotate, so as to drive the plugging ball 505 to rotate through the rotating rod 504, so that the diversion hole 506 allows the dispensing liquid in the dispensing tube 3 to pass through. Then, the dispensing liquid drips on the dispensing position on the high-frequency transformer under the action of gravity. When dispensing is not required, the primary motor 501 is started again. The plugging ball 505 rotates to make the diversion hole 506 in the side position to block the diversion hole 506, so that the dispensing liquid in the dispensing tube 3 will not overflow, so as to reduce the waste of the dispensing liquid and the impact on the product quality caused by dripping on the high-frequency transformer.
[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
