Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rubber plug vulcanization, and particularly relates to a silicone oil spraying device. BACKGROUND

[0002] Spraying silicone oil on the surface of vulcanized rubber can effectively reduce the adhesion of dust on the surface of rubber, reduce the friction loss between rubber and other objects, and enhance the resistance of rubber. Rubber plug manufacturers generally spray silicone oil on the rubber plug after vulcanization when the rubber plug is still relatively hot to facilitate the solidification of the silicone oil.

[0003] The rubber plugs are connected to each other after vulcanization, and the whole is a sheet-shaped rubber part. The traditional silicone oil spraying on the surface of the rubber plug after vulcanization is a manual operation. The operator holds a silicone oil spray head and sprays silicone oil uniformly on the surface of the rubber plug in all directions. The spraying effect and efficiency are highly dependent on the operator. Some manufacturers spray the rubber plug. First, place the rubber plug with the front face upward on the workbench, and then use a reciprocating automatic silicone oil spray head to uniformly spray silicone oil on the rubber plug. After the front face of the rubber plug is sprayed, the operator flips the rubber plug and completes the back face spraying of the rubber plug by using the automatic silicone oil spray head. The Chinese utility model patent with publication number CN213855267U discloses a hook type spraying machine. The spraying machine realizes full-automatic spraying of workpieces by a paint spraying gun arranged in a box body and a moving device capable of clamping workpieces and moving the workpieces up and down and rotating the workpieces by 360 degrees.

[0004] The rubber plug is flipped manually after the front face is sprayed, and then the back face is sprayed, which takes a long time. During the spraying of the front face of the rubber plug, the back face of the rubber plug is in contact with the workbench, which significantly reduces the temperature, which is not conducive to the solidification of the silicone oil sprayed on the back face of the rubber plug. The Chinese utility model patent with publication number CN213855267U uses a fixing device to suspend the workpiece in the case of fixedly arranging the paint spraying gun, and uses a moving mechanism connected with the fixing device to realize the rotation of the workpiece in the horizontal direction and the lifting of the workpiece in the plumb direction, so as to realize the full automation of the paint spraying of the workpiece. However, when this scheme is used to spray silicone oil on the sheet-shaped rubber part, the spraying of silicone oil on one side of the sheet-shaped rubber part will be accompanied by a significant temperature drop on the other side. The solidification temperatures of the silicone oil sprayed on the two sides of the sheet-shaped rubber part are quite different, which finally leads to a large difference in the solidification of the silicone oil on the front and back sides of the sheet-shaped rubber part. In addition, the sheet-shaped rubber part in the suspended state is easy to shake after being impacted by the silicone oil sprayed by the silicone oil spray head, which leads to uneven spraying of the silicone oil.

[0005] Therefore, it is necessary to improve the silicone oil spraying device in the prior art. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0028] The specific implementation of the utility model will be further described in combination with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0029] Example 1

[0030] like Figures 1-4 As shown, the silicone oil spraying device of Example 1 includes a chassis 1, a silicone oil nozzle 2, and a moving component. The silicone oil nozzle 2 is connected to the inner wall of the chassis 1, and the moving component is fixedly arranged on the inner top wall of the chassis 1. The moving component includes a driving mechanism 3 and a strip clamping mechanism 4. The strip clamping mechanism 4 is provided with a clamping interval. The driving mechanism 3 includes a connected lifting driving member 301 and a rotating driving member 302, and also includes a heating component 5. The heating component 5 is fixedly connected to the strip clamping mechanism 4, and the heating component 5 is located on one side of the clamping interval.

[0031] Specifically, in the silicone oil spraying device, the strip clamping mechanism 4 is used to clamp the sheet rubber part, the lifting drive member 301 and the rotating drive member 302 are used to drive the strip clamping mechanism 4 to move in the plumb direction and rotate in the horizontal direction, and the heating component 5 is located on one side of the clamping interval, which can heat the sheet rubber part fixed to the clamping mechanism 4 on one side. When the silicone oil spraying device is in use, the operator first places the edge of the sheet rubber member in the clamping interval of the clamping mechanism 4, and drives the strip clamping mechanism 4 through the lifting drive member 301 and the rotating drive member 302 to make the front side of the sheet rubber member perpendicular to the straight line in which the silicone oil is sprayed from the silicone oil nozzle 2. At this time, the heating component 5 facing the back side of the sheet rubber member heats the sheet rubber member. When the surface temperature of the sheet rubber member is appropriate, the silicone oil nozzle 2 is turned on to spray the front side of the sheet rubber member, and the lifting drive member 301 drives the sheet rubber member to move in the plumb direction to complete the spraying of the front side of the sheet rubber member. The heating component 5 keeps heating the sheet rubber member throughout the whole process. Finally, the rotating drive member 302 drives the sheet rubber member to turn over, and the lifting drive member 301 cooperates with the silicone oil nozzle 2 to complete the remaining spraying operation.

[0032] The heating component 5 can be optionally an infrared heating component. It should be noted that when the heating part of the heating component 5 is large in volume, the entire back side of the sheet heating element can be heated, but the energy consumption is high; when spraying the back side of the sheet heating element, it needs to be removed, which is cumbersome.

[0033] Preferably, the heating assembly 5 includes a heating element 501 and a heating driver 502. The heating driver 502 is fixedly connected to the strip clamping mechanism 4 and the heating element 501. The heating element 501 is a strip heating element 501 and is parallel to the strip clamping mechanism 4. The heating driver 502 is a lifting heating driver 502. This structural arrangement allows the strip heating element 501 and the lifting heating driver 502 to cooperate to heat the entire back surface of the sheet rubber member. The lifting heating driver 502 drives the strip heating element 501 to rise and fall, thereby preventing the strip heating element 501 from obstructing the spraying operation on the back surface of the sheet rubber member.

[0034] The heating member 501 is a strip-shaped heating member 501. When the lifting and heating driving member 502 drives the strip-shaped heating member 501, the heating of the sheet-shaped rubber member in the plumb direction is in sequence, and the surface of the sheet-shaped rubber member at different heights in the plumb direction is prone to temperature difference. To cooperate with this, the number of the silicone oil spray heads 2 is not less than 2, and the silicone oil spray heads 2 are arranged along the same horizontal straight line. In specific implementation, the lifting and heating driving member 502 uniformly drives the strip-shaped heating member 501 from a higher position to a lower position in the plumb direction, while the strip-shaped heating member 501 heats the sheet-shaped rubber member. The lifting driving member 301 drives the sheet-shaped rubber member to move from the lower position to the higher position in the plumb direction at the same speed as the lifting and heating driving member 502. At the same time, the heated area of the sheet-shaped rubber member is always at the lower position of the sprayed area in the plumb direction.

[0035] The rotating driving member 302 is connected with the lifting driving member 301 and is arranged at a higher position in the plumb direction of the lifting driving member 301. To complete the rotation of the sheet-shaped rubber member in the horizontal direction, the rotating driving member 302 needs to drive the lifting driving member 301 and the sheet-shaped rubber member at the same time when rotating. After the rotating driving member 302 turns over the sheet-shaped rubber member, because the lifting driving member 301 and the sheet-shaped rubber member have large weight, and are affected by inertia, a long time is needed for the sheet-shaped rubber member to reach a stable state. Preferably, the top of the rotating driving member 302 is connected with the bottom of the lifting driving member 301, and the bottom of the rotating driving member 302 is connected with the top strip-shaped clamp 401. At this time, the rotating driving member 302 only needs to drive the sheet-shaped rubber member, and the sheet-shaped rubber member can reach a stable state in a short time after being turned over.

[0036] The sheet-shaped rubber member has large mass, and when the strip-shaped clamping mechanism 4 clamps the sheet-shaped rubber member, the sheet-shaped rubber member should be relatively fixed in the plumb direction without sliding. Preferably, the strip-shaped clamping mechanism 4 includes a top strip-shaped clamp 401 and a top locking member 402 that is locked with the top strip-shaped clamp 401. The top strip-shaped clamp 401 is provided with a top clamping interval, and is fixedly connected with the driving mechanism 3 and arranged horizontally.

[0037] Embodiment 2

[0038] As shown in Figure 5 , 6 , the silicone oil spraying device of embodiment 2 is based on embodiment 1, and the difference lies in that the strip-shaped clamping mechanism 4 further includes a bottom strip-shaped clamp 403 and a bottom locking member 404 that is locked with the bottom strip-shaped clamp 403. The bottom strip-shaped clamp 403 is provided with a bottom clamping interval, and the top strip-shaped clamp 401 and the bottom strip-shaped clamp 403 are arranged with a clamping space therebetween.

[0039] Specifically, when the front surface of the sheet-shaped rubber piece is sprayed, the sheet-shaped rubber piece will shake, especially the spraying direction of the spray gun 2 will shake, which is not conducive to uniform spraying of the silicone oil. The bottom strip-shaped clamp 403 and the bottom locking piece 404 are arranged, when the front surface of the sheet-shaped rubber piece is sprayed, the shaking range of the sheet-shaped rubber piece is reduced under the influence of the gravity of the bottom strip-shaped clamp 403 and the bottom locking piece 404.

[0040] In order to further reduce the shaking range of the sheet-shaped rubber piece when it is sprayed, the inner bottom wall of the cabinet 1 is provided with a rotating piece 6 and a lifting piece 7, the top of the rotating piece 6 is connected with the bottom of the bottom strip-shaped clamp 403, the bottom of the rotating piece 6 is connected with the top of the lifting piece 7, and the bottom of the lifting piece 7 is fixedly connected with the inner bottom wall of the cabinet 1. At this time, the bottom strip-shaped clamp 403 can be linked with the top strip-shaped clamp 401, that is, through the cooperation of the lifting driving piece 301, the rotating driving piece 302, the rotating piece 6 and the lifting piece 7, the bottom clamping interval and the top clamping interval can always be in the same plane.

[0041] Embodiment 3

[0042] As shown in Figure 7 , the silicone oil spraying device of embodiment 3 is based on embodiment 1, and the difference lies in that the inner side wall of the cabinet 1 is further provided with a lifting base 8 which is slidingly connected with the cabinet 1, and the lifting base 8 is fixedly connected with the silicone oil spray head 2.

[0043] Specifically, when the spray gun 2 is fixedly arranged on the inner side wall of the cabinet 1 and cooperates with the lifting driving piece 301 to spray the sheet-shaped rubber piece, the lifting of the lifting driving piece 301 will cause the sheet-shaped rubber piece to shake, which affects the spraying effect; and when the position of the sheet-shaped rubber piece is kept fixed during spraying, only the lifting of the lifting base 8 can control the lifting of the spray head 2 to reduce the shaking range.

[0044] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the technical principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
