[0039] Reference Figures 1 to 7 The embodiment of the present invention provides a fixed-length pipe cutting mechanism, which includes a frame 100, and a pipe delivery assembly 200 and a pipe cutting assembly 300 both arranged on the frame 100. The pipe cutting assembly 300 and the pipe delivery assembly 200 are arranged in front and behind each other. The pipe cutting assembly 300 is provided with a pipe outlet hole 321 for the hose to pass through, wherein the pipe delivery assembly 200 can deliver the hose and move the hose forward through the pipe outlet hole 321 by a preset amount. The pipe cutting assembly 300 can cut the hose to obtain a hose of a preset length that moves forward through the pipe outlet hole 321.

[0040] Through the above structure, the pipe conveying assembly 200 can convey the hose, so that the hose moves forward by a preset amount through the pipe outlet hole 321, and the pipe cutting assembly 300 can cut the hose to obtain a hose of a preset length that moves forward through the pipe outlet hole 321. In other words, the pipe conveying assembly 200 and the pipe cutting assembly 300 set on the frame 100 can cooperate with each other to cut out a hose of a preset length, wherein the above-mentioned process of cutting to obtain a hose of a preset length does not require manual participation. Therefore, when it is necessary to cut out a large number of hoses of a preset length, the use of the fixed-length pipe cutting mechanism of the present application can greatly reduce the labor intensity of production personnel. Moreover, the mechanized fixed-length cutting action of the fixed-length pipe cutting mechanism of the present application can stabilize the floating amplitude of the length difference of the hoses cut from the same batch within a smaller range, so as to ensure that the specifications of the hoses cut from the same batch are close to the same.

[0041] The delivery pipe assembly 200 includes a first driving member 210 and a second driving member 220 .

[0042] Reference Figure 4 and Figure 5 The first driving member 210 is provided on the frame 100. The output end of the first driving member 210 is connected to the first rotating wheel 410. The first rotating wheel 410 is rotatably connected to the frame 100 and is provided with a first groove. The second driving member 220 is provided on the frame 100. The output end of the second driving member 220 is connected to the second rotating wheel 420. The second rotating wheel 420 is rotatably connected to the frame 100. The first rotating wheel 410 and the second rotating wheel 420 are arranged vertically. The second rotating wheel 420 is provided with a second groove. The second groove and the first groove are correspondingly arranged to form a channel S1 for the rubber hose to pass through. The first driving member 210 can drive the first rotating wheel 410 to rotate, and the second driving member 220 can drive the second rotating wheel 420 to rotate, so as to transport the rubber hose passing through the channel S1 and the pipe outlet 321.

[0043] It can be understood that the upper and lower sides of the hose passing through the channel S1 are respectively in contact with the first rotating wheel 410 and the second rotating wheel 420. When the first rotating wheel 410 and the second rotating wheel 420 rotate, the force exerted by the first rotating wheel 410 and the second rotating wheel 420 on the hose passing through the channel S1 can drive the hose passing through the channel S1 to move.

[0044] It is understandable that the hose of a corresponding preset length can be output by setting the rotation speed and rotation time of the first rotating wheel 410 and the second rotating wheel 420 .

[0045] In this embodiment, referring to Figure 4 and Figure 5There are two first wheels 410 and two second wheels 420, and the two first wheels 410 and the two second wheels 420 are arranged one-to-one up and down. The two first grooves and the two second grooves form two channels S1 in a one-to-one correspondence. The two channels S1 are both located in the front-to-back direction. The first driving member 210 can drive the two first wheels 410 to rotate, and the second driving member 220 can drive the two second wheels 420 to rotate.

[0046] In some embodiments, there are three first wheels 410 and three second wheels 420, and the three first wheels 410 and the three second wheels 420 are arranged one by one up and down, and the three first grooves and the three second grooves form three channels S1 one by one, and the three channels S1 are all located in the front and back directions. The first driving member 210 can drive the three first wheels 410 to rotate, and the second driving member 220 can drive the three second wheels 420 to rotate.

[0047] The second driving member 220 can drive the two second rotating wheels 420 to rotate. Figure 6 The second rotating wheel 420 is connected to the first gear 421. The frame 100 is rotatably connected to the second gear 130. The two first gears 421 are meshed with the second gear 130. The output end of the second driving member 220 is connected to one of the first gears 421. The second driving member 220 can drive one of the first gears 421 to rotate, thereby driving the two second rotating wheels 420 to rotate in the same direction. The second driving member 220 is configured as a motor.

[0048] In this embodiment, referring to Figure 5 The frame 100 is provided with a longitudinally movable mounting frame 510, the first driving member 210 and the first rotating wheel 410 are both provided on the mounting frame 510, and the frame 100 is rotatably connected with an adjusting member 520, which is threadedly connected to the mounting frame 510, wherein the adjusting member 520 can be rotated to drive the mounting frame 510 to rise and fall, so as to adjust the distance between the first rotating wheel 410 and the second rotating wheel 420.

[0049] Through the above structure, the distance between the first rotating wheel 410 and the second rotating wheel 420 can be adjusted so as to change the size of the channel S1 to accommodate the transportation of hoses with different diameters.

[0050] The first driving member 210 and the first rotating wheel 410 are both mounted on a mounting frame 510. The first driving member 210 is capable of driving the two first rotating wheels 410 to rotate. Specifically, the first rotating wheels 410 are connected to a third gear, and the mounting frame 510 is rotatably connected to a fourth gear. Both third gears are meshed with the fourth gear. The output end of the first driving member 210 is connected to one of the third gears. The first driving member 210 is capable of driving one of the third gears to rotate, thereby driving the two first rotating wheels 410 to rotate in the same direction. The first driving member 210 is configured as a motor.

[0051] It can be understood that the connection structure of the first driving member 210 driving the two first rotating wheels 410 to rotate is the same as the connection structure of the second driving member 220 driving the two second rotating wheels 420 to rotate. Therefore, the connection structure of the first driving member 210 driving the two first rotating wheels 410 to rotate can be compared with the connection structure of FIG. Figure 6 shown.

[0052] In order to avoid accidental contact with the adjusting member 520, the adjusting member 520 is rotated to lift the mounting frame 510. Figure 4 and Figure 5 The frame 100 is provided with a first connecting hole, the adjusting member 520 is provided with a second connecting hole, and the second connecting hole and the first connecting hole are detachably penetrated with a locking member 530 to limit the rotation of the adjusting member 520.

[0053] In order to make the hose pass straight into channel S1, refer to Figure 4 The frame 100 is provided with a first conduit member 110 for the hose to pass through, and the first conduit member 110 is located at the rear side of the channel S1.

[0054] The pipe cutting assembly 300 includes a support block 310 , a second guide tube member 320 , a tool holder member 330 and a third driving member 340 .

[0055] Reference Figure 2 、 Figure 4 as well as Figure 7 The supporting block 310 is arranged on the frame 100, and the supporting block 310 is provided with an avoidance hole 311. The second conduit member 320 is arranged on the front side of the supporting block 310, and the second conduit member 320 is provided with a pipe outlet hole 321. The tool holder member 330 can be longitudinally moved through the avoidance hole 311, and the tool holder member 330 is provided with a cutting knife 331. The third driving member 340 is arranged on the supporting block 310, and the output end of the third driving member 340 is connected to the tool holder member 330, wherein the third driving member 340 is configured as a cylinder member, etc. The third driving member 340 can drive the tool holder member 330 to move longitudinally, so that the cutting knife 331 cuts the hose supported on the supporting block 310.

[0056] In this embodiment, referring to Figure 4 The frame 100 is provided with a third conduit member 120, which abuts against the supporting block 310. A cutting gap S2 is provided between the third conduit member 120 and the second conduit member 320. The pipe assembly 200 is capable of conveying the hose, causing the hose to move forward through the third conduit member 120 and the pipe outlet hole 321 in sequence. The third driving member 340 is capable of driving the knife holder member 330 to move longitudinally, causing the cutting knife 331 to move through the cutting gap S2 to cut the hose.

[0057] It is understandable that the third conduit 120 abuts against the supporting block 310 , and the hose passing through the third conduit 120 is indirectly supported on the supporting block 310 .

[0058] It can be understood that the pipe outlet hole 321, the third conduit member 120, the channel S1 and the first conduit member 110 are all located in the front-to-back direction and are arranged in sequence from front to back. When the hose is passed through the first conduit member 110, the channel S1, the third conduit member 120 and the pipe outlet hole 321 in sequence, the hose is in a relatively straight state to facilitate the cutting action of the pipe cutting assembly 300.

[0059] In this embodiment, referring to Figures 1 to 3 The frame 100 is provided with a tube taking assembly 600, which can receive a hose of a preset length sent out from the tube outlet 321, and can bend the received hose into a U shape and then transport it to a preset position.

[0060] Through the above structure, the setting of the pipe assembly 600 can bend the cut preset length of the hose into a U shape and then transport it to a preset position, so that it can be received by other mechanisms of the hose installation equipment to achieve the connection between the gas pressure reducing valve body and the preset length of the hose.

[0061] The tube removal assembly 600 includes a fourth driving member 610 and a clamp assembly 620 .

[0062] Reference Figures 1 to 3 The fourth driving member 610 is arranged on the frame 100, and the fourth driving member 610 is set to two, and the clamp assembly 620 is set to two, and the two clamp assemblies 620 are respectively arranged on the two fourth driving members 610, wherein the fourth driving member 610 is set to a linear module, and the two fourth driving members 610 can respectively drive the two clamp assemblies 620 to move horizontally, and the two clamp assemblies 620 can respectively clamp and flip the two ends of the hose of a preset length to receive the hose of a preset length sent out from the pipe outlet 321, and bend the received hose into a U shape and then transport it to a preset position.

[0063] The clamp assembly 620 includes a clamp member 621 and a fifth driving member 622 .

[0064] Reference Figures 1 to 3The clamping member 621 is rotatably connected to the corresponding fourth driving member 610. The clamping member 621 is provided with a fifth gear 621A. The fifth driving member 622 is provided on the corresponding fourth driving member 610. The output end of the fifth driving member 622 is provided with a rack 622A. The rack 622A and the fifth gear 621A are engaged. The clamping member 621 can clamp the hose. The fifth driving member 622 can drive the rack 622A to move, thereby driving the clamping member 621 to flip via the fifth gear 621A. The clamping member 621 is configured as a pneumatic clamping jaw, etc., and the fifth driving member 622 is configured as a cylinder, etc.

[0065] It can be understood that the two fourth driving members 610 can respectively drive the two clamp assemblies 620 to move horizontally, and the two clamp assemblies 620 can respectively clamp and flip the two ends of the hose of preset length to receive the hose of preset length sent out from the pipe outlet 321, and bend the received hose into a U shape and then transport it to the preset position, that is, the receiving work and the bending and transfer work of the tube assembly 600 require the coordinated participation of the fourth driving member 610 and the clamp assembly 620.

[0066] Reference Figure 1 The receiving operation of the tube taking assembly 600 is specifically as follows: 1. The clamping member 621 located at the front side clamps one end of the hose delivered from the pipe outlet 321, and the corresponding fourth driving member 610 drives the clamping member 621 located at the front side to move forward to cooperate with the hose to move out of the pipe outlet 321; 2. After the hose moves out of the pipe outlet 321 to a certain length and the pipe delivery assembly 200 stops working, the clamping member 621 located at the rear side clamps the other end of the hose delivered from the pipe outlet 321; 3. After the pipe cutting assembly 300 cuts the hose, the two clamping members 621 respectively clamp and receive the hose of the preset length.

[0067] Reference Figure 2 The bending and transferring work of the tube assembly 600 is specifically as follows: 1. The two fourth driving members 610 drive the two clamp members 621 forward respectively; 2. During the forward movement of the two clamp members 621, the two fifth driving members 622 drive the two racks 622A to move, so as to drive the two clamp members 621 to flip, thereby driving the clamped rubber hose of the preset length to bend into a U shape. Among them, since the two fourth driving members 610 drive the two clamp members 621 forward respectively, the rubber hose of the preset length after being bent into a U shape will be transported to the preset position.

[0068] The present invention also provides a hose installation device, which includes the above-mentioned fixed-length pipe cutting mechanism. Through the above-mentioned structure, a hose of a preset length can be automatically cut and the connection between the gas pressure reducing valve body and the hose of the preset length can be automatically completed.

[0069] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
