It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1-3, the present application relates to a heated gear type metering device. The heating gear type metering device includes: a servo motor 1; the servo motor 1 is a motor capable of controlling position, speed and acceleration; the motor control system is characterized by comprising a motor and a feedback device, wherein the feedback device can measure the motion state of the motor and transmit information to the control system, and the control system adjusts a control signal of the motor by comparing the difference between the actual position and the target position according to the required motion parameters, so that the motor moves according to a preset track, and a high-precision control mode can be ensured. Meanwhile, by adopting the control design of the servo motor 1, the accurate control of the metering device can be realized, the overall precision of the metering device is improved, and the waste of materials can be reduced; and, can make the overall accuracy of the metering device reach + -1%.
The speed reducer 2 is connected with the output end of the servo motor 1; the speed reducer 2 is a mechanical transmission device for reducing the output speed of a motor or other driving apparatus and increasing the output torque. It does this by converting high-speed rotational motion on the input shaft into low-speed high-torque motion on the output shaft. It will be appreciated that the main components of the speed reducer 2 include an input shaft, an output shaft, a gear set and a housing 3. The input shaft is typically connected to the drive means and the output shaft is connected to the driven means. The gear set consists of a group of gears, wherein the gears comprise gears with different sizes and types, and the power transmission and the speed reduction are realized through the meshing between the gears; the speed reducer 2 can realize different reduction ratios, namely, the number of turns of the output shaft is correspondingly reduced when the input shaft rotates once. The reduction ratio determines the speed and torque of the output shaft in relation to the input shaft. In general, a larger reduction ratio may provide a higher output torque, but a reduced speed.
The coupler 15 is connected with the output end of the speed reducer 2; the coupling 15 is a mechanical device for connecting two shafts or between a shaft and a rotating device. Its main function is to transmit rotational motion and torque while allowing a degree of axial, radial and angular misalignment.
The coupling 15 is usually composed of two interconnected parts, each fixed to the shaft to be connected. These parts may be gears, elastic elements (e.g. springs, rubber) or similar members. When one shaft rotates, rotational moment is transmitted to the other shaft through the coupling 15, so that synchronous motion of the two shafts is realized, and the effects of convenient coupling and decoupling, vibration absorption and impact and torque transmission are achieved.
The gear pump 4 is connected with the output end of the coupler 15; the gear pump 4 is a conventional positive pressure centrifugal pump that utilizes a pair of intermeshing gears to transfer liquid or fluid. It mainly consists of a driving gear and a driven gear, and the two gears are meshed to form a sealed cavity to suck liquid or fluid from an inlet and push the liquid or fluid to an outlet.
The working principle of the gear pump 4 is based on the change of volume, and when the driving gear rotates, the driven gear also rotates. Due to the meshing of the gears, the volume of the seal cavity gradually decreases, so that liquid or fluid is sucked into the seal cavity. As the gear continues to rotate, the volume of the sealed cavity increases pushing out the liquid or fluid. In this way, the rotation of the gears can continuously suck and discharge liquid or fluid, and the functions of conveying and increasing pressure are realized. Meanwhile, the gear pump 4 has more specifications to be selected, so that the flow of the metering device can be improved, and the applicability of the metering device is wider. Such as: the gear pump 4 has a selectable specification of 0.05cc/rev to 100cc/rev, and the rotation speed of the gear pump 4 is in the range of 5-200rpm, so that the range of glue amount of 0.25-20,000 cc/min can be realized.

A heating member 5 provided on one side of the connection block 16; good heating effect can be realized to ensure good circulation of glue, and then avoid the runner to take place the condition of jam, finally influence the effect of play glue. Meanwhile, the problems that the gear pump 4 is easy to power and not stop when conveying materials with high viscosity, the service life is shortened and the flow channel is blocked can be solved, the temperature of the gear pump 4 and the flow channel thereof is controlled by adopting a heating rod and a temperature sensor 6 to monitor, so that the viscosity of conveying fluid is reduced, the viscosity of the fluid is lowered, the power burden on the gear pump 4 is small, the service life of a metering device can be prolonged, the condition of the flow channel blockage is reduced, and the glue within the range of 0-1,000,000 cps can be conveyed.
A first mounting plate 10 provided adjacent to the heating member 5 on the connection block 16 side; good fixing and mounting effects can be achieved, thereby ensuring good component assembly effects.
A distribution valve 9 penetrating the first mounting plate 10 in a first direction and communicating with the gear pump 4; the problem that when the gear pump 4 is used as a metering device, a switch valve is not installed at the outlet of the gear pump 4 to control the on-off of the whole metering device can be solved. It will be appreciated that the dispensing valve 9 is a device for controlling the flow direction and dispensing of a fluid (liquid or gas) in different pipes or systems. The valve is generally composed of a valve, an actuating mechanism and a controller, and the position or the opening degree of the valve can be manually or automatically changed to realize the distribution and the control of fluid; has the effects of fluid diversion, fluid conversion and flow regulation. The first direction refers to the Y-axis direction in a two-coordinate system, i.e. the vertical direction. By fixedly mounting the distribution valve on the first mounting plate 10 in the vertical direction, a good assembly effect can be achieved. At the same time, the dispensing valve communicates with the gear pump 4, which ensures a good circulation of glue. Meanwhile, a high-precision switch valve is arranged at the outlet of the gear pump 4, and the switch valve is used for controlling the on-off and the back suction of the whole metering device, so that the phenomenon of dripping and hanging of fluid materials with low metering viscosity can be avoided.
A solenoid valve 7 electrically connected to the distribution valve 9; the solenoid valve 7 is a device for controlling the flow of liquid or gas using electromagnetic principle. The electromagnetic valve consists of an electromagnetic exciter and a valve body, wherein the opening and closing of the valve body are controlled by changing the energizing state of the exciter; the method has the effects of quick response, high reliability and accurate control. By electrically connecting the electromagnetic valve 7 with the distribution valve 9, a good electric control effect on the distribution valve 9 can be realized, thereby realizing a precise control effect on the distribution valve 9; it can be understood that by electrically controlling the switching air passage of the electromagnetic valve, the change of the air passage changes the on-off of the distribution valve.
The servo motor 1 provides driving force to drive the speed reducer 2, the coupler 15 and the gear pump 4 to act in sequence, so that the gear pump 4 measures and conveys glue, and the electromagnetic valve 7 controls the distributing valve 9 to open and close so as to enable the glue to be discharged or closed. The servo motor 1, the speed reducer 2, the coupler 15 and the gear pump 4 are assembled and connected in sequence, so that a complete driving structure can be realized, and the effect of metering the glue by the gear pump 4 is ensured; at the same time, the electromagnetic valve 7 controls the distribution valve 9 to be opened or closed, so that the effect of opening or closing the glue can be controlled, and a good control effect is realized.
