Description

Technical Field

[0001] The invention relates to the technical field of hose production equipment, in particular to a double-belt driven full-automatic hose cutting machine. Background Art

[0002] In the production process of hydraulic hoses, it is usually necessary to cut the semi-finished hoses to length, clean the inner channel, assemble the joints and wrap the protective sleeves. Except for some products that can be made into caps without cutting, most of the other products need to cut off the excess material at both ends to make the length of the entire hose meet the requirements of the drawings. The existing cutting method is mainly manual saw blade cutting.

[0003] The existing publication number is CN110065101B, which is a plastic pipe cutting machine. It includes a frame, a mounting plate is provided on the frame, a mounting hole is provided on the mounting plate, a rotating disk is rotatably connected in the mounting hole, and a through hole is provided in the rotating disk for the pipe to pass through; a cutting device for cutting the pipe is also provided on the rotating disk, and the cutting device includes a cutting knife for cutting the pipe, a first connecting rod, a second connecting rod, a counterweight block and a hinge shaft; a limit block is provided on the rotating disk, and a reset device is also correspondingly provided on the rotating disk, and the reset device includes a mounting block provided on the rotating disk and a reset spring provided on the limit block; a driving motor for driving the rotating disk is also provided on the frame. By providing the cutting device, the pipe is cut by circular cutting, which reduces the situation where the cutter is interfered by the side wall of the pipe during the cutting process, thereby making the cut end surface of the pipe more flat; The traditional cutting device has the following main disadvantages: When cutting the hose, the length is measured manually with a ruler, and the length is often unqualified due to negligence and other reasons; The cutting process requires manual use of the handle to push the hose into the cutter. Thicker hoses require a lot of strength and skill to complete the cutting work, which reduces production efficiency and increases work intensity. When cutting the hose, high-speed friction between the hose and the cutter will generate high temperature, and impurities with low ignition points on the surface of the hose will burn, posing a threat to production safety.

[0012] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: The conveying direction of the hose is limited by the limit rod. At the same time, the hose generates friction on the meter wheel encoder due to the pressure of the upper limit roller. As a result, the meter wheel encoder is driven to rotate by the friction when the hose is conveyed, so that the length of the conveyed hose can be calculated, and the meter wheel encoder transmits the length to the PLC, so that the entire device has a high pass rate when cutting the hose. After the preset cutting length is reached, the conveying component 3 stops working, the pressing component squeezes the hose downward to bend it, and the cutting component moves upward to cut the hose. During cutting, due to the bending of the hose, the cutting edge will be broken apart, thereby preventing the incision from cutting the component. After the cutting is completed, the pressing part is lifted, and the hose continues to be conveyed for the next conveying work.

[0013] When it is necessary to cut the hose, the tensioning cylinder pushes the sliding plate, so that the slider 2 slides on the guide rail and moves toward the middle position, thereby making the synchronous wheel, the rack and the synchronous belt move toward the middle position. The above structure is symmetrically arranged about the middle position, so when the rack moves toward the middle position, the meshing action between the rack and the gear drives the rack symmetrically arranged with it to move toward the middle position, thereby making the symmetrically arranged synchronous belt and the synchronous wheel move toward the middle position together, and the hose is tightened by the synchronous belt, so that friction is generated between the synchronous belt and the hose, and the synchronous wheel is driven to rotate by the servo motor. The hose is transported by the transmission action of the synchronous belt, which makes the production efficiency higher and the work intensity of the workers greatly reduced.

[0014] The hose passes through the feed port and the gear ring, and spring 1 is squeezed. When the connecting plate moves back and forth, push rod 1 slides on the arc-shaped slide rail. During the sliding process, push rod 2 is pushed out, and spring 2 is compressed. Through the meshing action of rack 2 and the gear ring, the gear ring rotates and drives the dust removal brush slidably connected to it to rotate to clean the surface of the hose, avoiding the safety hazard caused by the burning of impurities on the surface of the hose due to the high temperature generated by the friction between the hose and the cutting saw blade.

[0020] One end of the hose passes through the dust removal component 52 and enters the conveying component 3 in an unwinding manner, slides in the guide groove, and is conveyed to the counting component 4 through the conveying component 3. During the continued unwinding process, the counting component 4 calculates the unwinding length and transmits the length to the PLC. The PLC then calculates the conveying length of the hose and controls the conveying component 3. After reaching the preset cutting length, the conveying component 3 stops working, the pressing component 21 squeezes the hose downward to bend it, and the cutting component 22 moves upward to cut the hose. After the cutting is completed, the pressing part is lifted, and the hose continues to be conveyed for the next conveying work.

[0024] While the hose is squeezed downward by the pressing block 213, the cylinder pushes the slider 222 to slide upward, so that the cutting motor 224 drives the cutting saw blade 225 to move upward together to cut the hose. During the cutting process, the friction will cause the cut part of the hose to generate smoke in the smoke collection chamber 226 due to the high temperature, and the debris generated by the cutting will be discharged through the smoke purifier 227.
