DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with specific implementation methods and with reference to the accompanying drawings. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present invention and its applications.

[0027] like Figure 1 The above-mentioned embodiment provides a high-temperature resistant grease dispensing device for a silencer sheet, which includes a base 1, a conveying mechanism 6, a dispensing mechanism 7 and a control mechanism 15.

[0028] A grease preparation mechanism is provided on the base 1 , and the grease preparation mechanism includes a grease preparation barrel 2 , through which the required grease is prepared.

[0029] The conveying mechanism 6 is an existing traditional transmission mechanism, which is located on one side of the base 1 and is used to transport the silencer sheet. It cooperates with the dispensing mechanism 7 and the control mechanism 15 to realize automatic transportation and dispensing of the silencer sheet.

[0030] The dot coating mechanism 7 is located on one side of the conveying mechanism 6. The dot coating mechanism 7 can be on the same side or different side as the base 1. In this embodiment, the former is preferred. The dot coating mechanism 7 includes a limit component and a quantitative oil outlet component. The limit component includes a distance sensor 8 and a positioning telescopic rod 9. In this embodiment, the distance sensor 8 and the positioning telescopic rod 9 are preferably fixed on the side of the conveying mechanism 6, and the positioning telescopic rod 9 is arranged downstream of the distance sensor 8. Figure 2-3 As shown, of course, in other embodiments of the present application, the distance sensor 8 and the positioning telescopic rod 9 can also be fixed at other feasible and reasonable positions. The distance sensor 8 is an infrared sensor, which is used to sense the position of the silencer on the conveying mechanism 6. The positioning telescopic rod 9 is an electric telescopic cylinder. The positioning telescopic rod 9 can be extended when the silencer moves to the specified position to block and position it. In this embodiment, the distance sensor 8 and the positioning telescopic rod 9 preferably form a positioning circuit. Specifically, the distance sensor 8 senses whether the silencer reaches the specified position through an infrared signal. If it senses that the silencer reaches the specified position, the positioning telescopic rod 9 is started to extend to block the silencer that is about to pass through. The positioning telescopic rod 9 can automatically retract after being extended for a preset time. It can be understood that the positioning telescopic rod 9 does not retract after it retracts. It affects the normal operation of the silencer on the conveying mechanism 6. Moreover, it is understandable that the distance between the positioning telescopic rod 9 and the upper end face of the conveying mechanism 6 should be less than the thickness of the silencer, so that the blocking and limiting of the silencer can be achieved; the quantitative oil discharge assembly includes a column 10 and an L-shaped crank arm 11. The L-shaped crank arm 11 includes a horizontal arm and a vertical wall. The horizontal arm is movably mounted on the upper end of the column 10 through a driving mechanism 14. One end of the vertical arm is equipped with a quantitative oil discharge valve 13 located above the conveying mechanism 6 and connected to the grease preparation barrel 2 through an oil inlet pipe 12. The movement of the L-shaped crank arm 11 can drive the quantitative oil discharge valve 13 to move and then position it directly above the silencer for spot coating. It is understandable that the oil outlet of the quantitative oil discharge valve 13 should be opposite to the required coating part of the silencer to ensure accurate and quantitative coating.

[0031] It can be understood that the equipment of this embodiment should include a control mechanism 15, which is electrically connected to the conveying mechanism 6, the limiting component, the quantitative oil outlet component and the driving mechanism 14. The control mechanism 15 serves as a control terminal and can receive and issue instructions to control the corresponding actuator action. It should be noted that this embodiment adopts conventional control circuits and principles. At the same time, the improvement is not in the control method. Therefore, this embodiment omits the description of the specific electrical connection between the control mechanism 15 and the conveying mechanism 6, the limiting component, the quantitative oil outlet component and the driving mechanism 14.

[0032] In this embodiment, in order to ensure the normal use of the quantitative oil outlet valve 13 without interference from the distance sensor 8 and the positioning telescopic rod 9, the quantitative oil outlet valve 13 is preferably located between the distance sensor 8 and the positioning telescopic rod 9.

[0033] In this embodiment, the driving mechanism 14 is fixed to the top of the column 10 through the support base 19. The driving mechanism 14 includes a driving motor 18 and a transmission member. The driving motor 18 is connected to the L-shaped turning arm 11 through the transmission member, thereby driving the L-shaped turning arm 11 to move.

[0034] In this embodiment, the transmission member is a transmission shaft 16 or a conveyor belt 17.

[0035] When it is a transmission shaft 16, the driving motor 18 is connected to the L-shaped crank arm 11 through the transmission shaft 16, and drives the L-shaped crank arm 11 to drive the quantitative oil outlet valve 13 to move in an arc trajectory. Specifically, the driving motor 18 is fixed on the support seat 19, and its power shaft is connected to the transmission shaft 16 and is arranged in the vertical direction. The horizontal arm of the L-shaped crank arm 11 is vertically docked with the transmission shaft 16. When the driving motor 18 drives the transmission shaft 16 to rotate, it will drive the L-shaped crank arm 11 to rotate and then drive the quantitative oil outlet valve 13 to move in an arc trajectory. When running along the arc trajectory, the quantitative oil outlet valve 13 can approach or move away from the conveying mechanism 6. When spot coating is required, the driving motor 18 drives the quantitative oil outlet valve 13 to approach the conveying mechanism 6 and move it above the conveying mechanism 6 to face the required coating position of the silencer. When coating is completed, the driving motor 18 drives the quantitative oil outlet valve 13 away from the conveying mechanism 6 and returns to its position. Figure 1 or Figure 4 As shown; adopting this structure can reduce the volume of the driving mechanism 14, thereby reducing the weighing weight of the column 10.

[0036] When it is a conveyor belt 17, the conveyor belt 17 is fixed on the support seat 19, and its travel direction is perpendicular to the axial direction of the conveying mechanism 6. The horizontal arm of the L-shaped turning arm 11 is fixed on the conveyor belt 17 and can move synchronously with the conveyor belt 17. When the driving motor 18 drives the conveyor belt 17 to move, it can drive the L-shaped turning arm 11 and the quantitative oil outlet valve 13 thereon to move in a straight line, such as Figure 5-6 As shown; specifically, the travel direction of the conveyor belt 17 is perpendicular to the axial direction of the conveying mechanism 6, and the travel path of the conveyor belt 17 extends along the width direction of the conveying mechanism 6. When coating is required, the conveyor belt 17 drives the L-shaped turning arm 11 and the quantitative oil outlet valve 13 thereon to move toward the conveying mechanism until reaching the specified position. After coating is completed, the conveyor belt 17 drives the L-shaped turning arm 11 and the quantitative oil outlet valve 13 thereon to move away from the conveying mechanism until they are reset. Although this structure increases the volume of the driving mechanism 14, it is convenient to adjust the position of the quantitative oil outlet valve 13 in the linear direction.

[0037] In this embodiment, during the coating process, coating can be performed only at designated points, or the quantitative oil outlet valve 13 can be moved intermittently to perform multi-point coating, depending on actual needs.

[0038] In this embodiment, in order to facilitate adaptation to silencers of different thicknesses, the column 10 is preferably an electric telescopic cylinder, so that the height distance of the quantitative oil outlet valve 13 relative to the conveying mechanism can be adjusted according to the thickness of the silencer.

[0039] In this embodiment, the grease preparation mechanism also includes a telescopic bracket 3, which is fixed on the base 1, and a stirring mechanism is mounted on the telescopic bracket 3. The stirring mechanism includes a stirring motor 4 and a stirring blade 5. The stirring blade 5 extends into the grease preparation barrel 2. When in use, the stirring blade 5 can accelerate the preparation of the grease, ensure that the grease is evenly prepared, and improve the efficiency of the grease preparation.

[0040] The telescopic bracket 3 is composed of a plurality of electric telescopic cylinders. By adjusting the height of the telescopic bracket 3, the position of the stirring blade 5 relative to the grease preparation barrel 2 can be adjusted according to the grease dosage, ensuring that the stirring blade 5 effectively stirs.

[0041] In this embodiment, the liquid inlet pipe arranged between the quantitative oil outlet valve 13 and the grease preparation barrel 2 is fixed by a telescopic bracket 3. By adjusting the height of the telescopic bracket 3, the position (depth) of the liquid inlet pipe in the grease preparation barrel 2 can be adjusted to ensure effective liquid suction; it can be understood that a grease supply pump should be provided on the liquid inlet pipe.

[0042] In this embodiment, the quantitative oil outlet valve 13 may be an existing conventional regulating valve, which can adjust the liquid outlet volume by controlling the valve opening.

[0043] The operating principle of this embodiment includes: first, the required coating grease is prepared through the grease preparation barrel 2, and then the conveying mechanism 6 is started to convey the silencer. At the same time, the distance sensor 8 senses the position of the silencer on the conveying mechanism 6 in real time through infrared rays. When the silencer is sensed to move to the specified position, the positioning telescopic rod 9 extends to block the currently sensed silencer. At this time, the driving mechanism 14 is started to drive the L-shaped crank arm 11 to move and then drive the quantitative oil outlet valve 13 to move to the top of the required coating part of the silencer, and the quantitative oil outlet valve 13 is started to discharge oil to complete the coating; after the coating is completed, the positioning telescopic rod 9 is retracted and reset, and the silencer continues to move with the conveying mechanism to the specified position.

[0044] In summary, the device of this embodiment can realize automatic spot application of grease to the silencer plate, reducing labor and labor costs. In addition, the quantitative oil outlet valve 13 can provide the required amount of grease to the silencer plate, which not only improves the grease utilization rate, but also improves the grease coating quality and efficiency of the silencer plate; and solves the existing deficiencies.

[0045] The above is only an embodiment of the present invention. The commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims. The specific implementation methods and other records in the specification can be used to interpret the content of the claims.
