Description
Technical Field
The invention relates to the technical field of glue guns, in particular to a glue discharging control method and device of a hot melt glue gun and the hot melt glue gun.
Background
The hot melt adhesive gun can melt the adhesive rod into fluid and push the adhesive rod to move forwards, so that the hot melt adhesive melted into the fluid flows out of the gun head, and the fluid hot melt adhesive is coated on an object to be adhered, so that the hot melt adhesive can be adhered to the object to be adhered, and is commonly used for operations such as joint filling, joint repairing and the like in industrial or household construction. The existing hot melt glue gun generally comprises a control circuit, a motor, a pushing device and a trigger switch, wherein when the trigger switch is triggered, the control circuit drives the motor to rotate in the positive direction, the motor drives the pushing device to move forwards, so that the pushing device pushes a glue stick to move, and when the trigger switch is continuously triggered, the motor continuously rotates; when the trigger switch is triggered, the motor stops rotating forwards, in order to prevent molten glue from overflowing the gun head, the control circuit drives the motor to rotate reversely, so that the pushing device retracts, when the pushing device retracts, the pressure between the pushing device and the glue stick is instantly reduced, the glue stick can automatically retract under the action of the internal pressure of the glue stick, and the motor stops rotating after continuously rotating backwards for a set time.
The hot melt glue gun has the advantages that as long as the trigger switch is triggered once, the motor continuously rotates reversely for a set time, so that the pushing device retreats for a set distance, and the time length of the trigger switch which is continuously triggered is irrelevant. If the trigger switch is continuously triggered in a certain operation for a time shorter than the time set by the continuous reverse rotation of the motor, the forward distance of the pushing device in the operation is shorter than the set backward distance of the pushing device, and when the pushing device is already retracted to the limit position, if the motor continuously rotates reversely to forcibly drive the pushing device to retract, the motor or the gun body of the hot melt glue gun is likely to be damaged. The hot melt glue gun is generally handheld, and sometimes the gun cannot be prevented from being operated by mistake, namely the trigger switch is inching (the duration of continuous triggering is extremely short), if the trigger switch is inching for many times due to misoperation, the probability of damage to the motor or the gun body of the hot melt glue gun is greatly increased.
