Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting, in particular to a hose cutting machine and method with a hose cutting surface that does not deform. Background Art

[0002] Plastic pipes are widely used in life. With the development of the industry, the requirements for hose cutting are getting higher and higher. Not only the size is required to be precise, but also the cutting deformation and end face accuracy of the cutting surface are also very high. This is especially true for the cutting of unvulcanized hoses, which have low strength and are easy to deform.

[0003] When the cutting machine cuts the rubber tube, the force on both ends is uneven, and the cut is generally uneven. At the same time, the notch is easily deformed by pulling, affecting the overall aesthetics of the processing. The cut surface formed by the general punching method is easy to deform, affecting the product quality, causing a large number of rubber hoses to be unqualified, and greatly increasing the processing cost.

[0004] Therefore, we propose a hose cutting machine and method with no deformation of the hose cutting surface to solve the above problems. The deformation of the hose cutting surface is reduced by heating the cutting knife to a certain extent. At the same time, the cutting debris on the cutting knife can be cleaned by a cleaning brush. The operation is simple, the deformation of the hose is reduced, and the processing efficiency is improved. Summary of the invention

[0005] In order to achieve the above-mentioned purpose of simple operation, reducing the deformation of the hose and improving the processing efficiency, the present invention provides the following technical solutions: a hose cutting machine with a non-deformed cross-section of the hose, comprising a chassis, the inside of which is movably connected to the hose to be cut, a warning light fixedly installed on the top of the chassis, a conveying platform fixedly installed on the left side of the chassis, a fixed base fixedly installed inside the chassis, a support column fixedly installed on the top of the fixed base, a fixed platform fixedly connected to the top of the support column, a slide groove opened inside the fixed platform, a slider movably connected inside the fixed platform, a heat conductive layer fixedly connected to the bottom of the slider, and a heat conductive layer fixedly connected to the bottom of the heat conductive layer A cutting knife, a heating wire is fixedly installed inside the slider, a semiconductor refrigeration plate is fixedly installed inside the slider, a resistor is fixedly installed inside the fixed platform, a movable rod is fixedly installed outside the fixed platform, an electric push rod is movably connected inside the movable rod, a control valve is fixedly installed inside the movable rod, a cleaning brush is also movably connected to the outside of the movable rod, a piston is fixedly connected to the bottom of the movable rod, a sealing tube is fixedly installed inside the fixed base, a connecting spring is movably connected inside the sealing tube, an extrusion rod is movably connected outside the connecting spring, a fixed plate is fixedly connected to the outside of the extrusion rod, and the sealing tube is filled with a balancing liquid.

[0006] As an optimization, a transmission belt is provided on the top of the conveying platform, a warning light is fixedly installed inside the fixed platform, and a support column is perpendicular to the horizontal plane.

[0007] As an optimization, both sides of the slider are provided with protrusions and movably connected with the slide groove. The cutting knife is made of stainless steel. When the device is working, the hose to be cut is placed inside the chassis, and the hose to be cut is placed on the top of the fixed table. At this time, the machine is started and the slider moves downward inside the slide groove.

[0008] As an optimization, the cold end of the semiconductor refrigeration plate is connected to the fixed platform, and the hot end of the semiconductor refrigeration plate is connected to the heating wire. The heating wire heats the cutting knife. As the slider moves downward, the movable rod moves downward to push the piston to squeeze the balancing liquid, so that the extrusion rod pushes the fixed plate inward, and the connecting spring is stretched at this time.

[0009] As an optimization, the resistor is connected to the output end of the semiconductor refrigeration plate, and the resistor is electrically connected to the warning light. When the temperature is too high, the temperature difference between the hot end and the cold end of the semiconductor refrigeration plate is large, and the generated working voltage is greater than the minimum path voltage of the resistor. The resistor is connected, and the warning light lights up to remind the operator to take action. The operation is simple and the safety performance is good.

[0010] As an optimization, the interior of the movable rod is filled with cleaning liquid, the diameter of the electric push rod is equal to the diameter of the movable rod, and the movable rod is perpendicular to the fixed base. After the cutting is completed, the slider moves upward, and the movable rod moves upward, so that the piston moves upward, the connecting spring returns to its original length, and the extrusion rod returns to its original state. At this time, the control valve opens, and the electric push rod extends to squeeze the cleaning liquid inside the movable rod into the interior of the cleaning brush. The cleaning brush cleans the debris on the cutting knife to prevent adhesion, which causes the cutting knife to overheat.

[0011] As an optimization, the piston is located inside the sealing tube, and the diameter of the piston is equal to the sealing tube.

[0012] As an optimization, the outer diameter of the extrusion rod is equal to the sealing tube, and limiting devices are set on both sides of the fixed plate. The fixed plate fixes the hose.

After the cutting is completed, the slider moves upward, the movable rod moves upward, the piston moves upward, the connecting spring returns to its original length, and the extrusion rod returns to its original state. At this time, the control valve opens, and the electric push rod extends to squeeze the cleaning liquid inside the movable rod into the interior of the cleaning brush;

[0018] S5. Use a cleaning brush to clean the debris on the cutting knife to prevent adhesion, which will cause the temperature of the cutting knife to be too high. When the temperature is too high, the temperature difference between the hot end and the cold end of the semiconductor refrigeration piece is large, and the generated working voltage is greater than the minimum path voltage of the resistor, and the resistor is connected;

[0019] S6. At this time, the warning light is on to remind the operator to handle it. The operation is simple and the safety performance is good.

[0020] The beneficial effects of the present invention are: the hose cutting machine and method with no deformation of the cross-section of the hose, the downward movement of the slider drives the movable rod to move, so that the balancing liquid pushes the fixed plate to move to fix the hose to be cut, and at the same time, the hose is cut by heating the electric heating wire to prevent the hose from being deformed. At the same time, the semiconductor cooling plate and the warning light are used in conjunction to prevent the temperature of the cutting knife from being too high, causing the hose and the cutting knife to stick together.
