Description
Technical Field
[0001] The present invention relates to a suction device for a hose. Background Art
[0002] Currently, when using hoses such as oxygen hoses by inserting and connecting, it is necessary to manually pick them up, resulting in low efficiency and easy contamination of the hoses. Therefore, it is very necessary to provide a suction device for hoses that can automatically pick up hoses, which can reduce the labor intensity of workers, achieve mechanized picking operations, improve efficiency, and reduce the contamination of hoses. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a suction device for a hose that can automatically pick up hoses, reduce the labor intensity of workers, achieve mechanized picking operations, improve efficiency, and reduce the contamination of hoses.
[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:
[0005] A suction device for a hose includes a suction device main body and a suction part. The bottom of the suction device main body is hermetically connected to the top of the suction part. Inside the suction device main body, there is one or more independent vacuum channels. Through holes are opened on the side wall of the suction device main body, and the through holes are connected to the upper part of the vacuum channels. The lower end of the vacuum channels penetrates through the bottom surface of the suction device main body. At the bottom of the suction part, there are one or more spaced suction grooves. Along the length direction of the bottom of the suction groove, there are two or more spaced through grooves, and the through grooves penetrate through the top surface of the suction part. The lower end of the vacuum channels is correspondingly connected to the through grooves of the suction grooves. On the outside of the suction grooves at the bottom of the suction part, there are guide grooves, and the suction grooves are connected to the guide grooves, and the guide grooves gradually narrow from the outside to the inside. With such a structure, the hose below the guide groove evacuates the vacuum channels through the through holes, sucking the hose into the suction grooves, preventing the hose from being sucked into the vacuum channels. Then, the suction device that has sucked the hose is moved to a set position, the vacuum pumping is stopped, and the vacuum channels are inflated through the through holes, releasing the adsorption state of the hose, and the hose falls from the suction grooves, thus completing the suction work of the hose and achieving mechanized suction operations.
[0006] As an improvement of the present invention, the vacuum channels include an upper vacuum channel and a lower vacuum channel that are connected. The vacuum channels are in a stepped shape with a smaller upper part and a larger lower part. The upper vacuum channel is connected to the through holes on the side wall, and the lower vacuum channel is correspondingly connected to the through grooves of the suction grooves. With such a structure, the suction area of the suction device for the hose can be increased, enhancing the adsorption ability.
[0007] As an improvement of the present invention, the suction groove includes two parallel side surfaces and a semi-circular bottom surface that is concave inward. The semi-circular bottom surface is connected to the two side surfaces. The distance between the two side surfaces is equal to the outer diameter of the suction hose, and the diameter of the semi-circular bottom surface is equal to the outer diameter of the suction hose. With such a structure, the suction area of the suction device on the hose can be increased, the adsorption capacity can be enhanced, the hose can be more closely fitted to the suction groove, and air leakage due to poor sealing can be prevented.
[0008] As an improvement of the present invention, the guiding groove is an inclined groove, the guiding angle of the guiding groove is 50 - 70°, and the depth of the guiding groove is equal to the outer diameter of the suction hose. With such a structure, the hose is easily sucked, ensuring the success rate of hose suction.
[0009] As an improvement of the present invention, the upper vacuum channel is a cylindrical hole, the lower vacuum channel is an oval hole, the diameter of the lower vacuum channel is larger than that of the upper vacuum channel, and the depth of the lower vacuum channel is 1.5 to 2 times the outer diameter of the suction hose. With such a structure, the suction speed and release speed of the hose are balanced, facilitating mechanized operation. When the depth of the lower vacuum channel is greater than 2 times the outer diameter of the suction hose, the release speed of the hose is slow. When the depth of the lower vacuum channel is less than 1.5 times the outer diameter of the suction hose, the suction speed of the hose is slow.
[0010] As an improvement of the present invention, the height of the two side surfaces of the suction groove is 0.3 - 0.7 times the outer diameter of the suction hose. With such a structure, the hose is easily sucked, ensuring the success rate of hose suction.
[0011] As an improvement of the present invention, two independent first vacuum channels and second vacuum channels are provided inside the main body of the suction device. First through holes and second through holes are opened on the side wall of the main body of the suction device. The upper part of the first vacuum channel is connected to the first through hole, the upper part of the second vacuum channel is connected to the second through hole. The first vacuum channel and the second vacuum channel are of the same shape and size, and are arranged side by side and parallel to each other in the main body of the suction device; two correspondingly spaced and parallel first suction grooves and second suction grooves are opened at the bottom of the suction part. Two spaced first through grooves are opened at the bottom of the first suction groove. The first through groove is an oval through groove. A first guiding groove is provided outside the first suction groove. Two spaced second through grooves are opened at the bottom of the second suction groove. The second through groove is an oval through groove. A second guiding groove is provided outside the second suction groove. With such a structure, the first suction channel composed of the first through hole, the first vacuum channel, the first suction groove, and the first guiding groove, and the second suction channel composed of the second through hole, the second vacuum channel, the second suction groove, and the second guiding groove can be used independently without interfering with each other. Any one of the suction channels can be selectively used, which can improve the efficiency of the suction device for sucking the hose.
[0012] As an improvement of the present invention, the suction device is in the shape of a cuboid, and the first through hole and the second through hole are arranged on opposite side walls of the main body of the suction device. With such a structure, the air connecting pipes cooperating with the first through hole and the second through hole can be arranged on the opposite side walls of the main body of the suction device, facilitating the connection of the air pipes and convenient for installation, operation and maintenance.
[0013] As an improvement of the present invention, the bottom of the main body of the suction device and the top of the suction part are welded or detachably connected.
[0014] As an improvement of the present invention, a first connection hole is formed in the middle of the top surface of the main body of the suction device, and the first connection hole is a blind hole. With such a structure, it is convenient to connect the suction device with other supporting equipment to achieve mechanized operation.
[0015] Compared with the prior art, the present invention at least has the following technical effects: A suction device for a hose according to the present invention can evacuate the vacuum channel through the through hole for the hose below the guiding groove, suck the hose into the suction groove, prevent the hose from being sucked into the vacuum channel, then move the suction device sucking the hose to a set position, stop evacuating, inflate the vacuum channel through the through hole, release the adsorption state of the hose, and let the hose fall from the suction groove, thus completing the suction work of the hose and achieving mechanized suction operation.
