Description

Technical Field

[0002] At present, most domestic rail vehicles use open corrugated tubes or open textile sleeves to wrap around the outside of the cables to protect them. The space under the Chongqing monorail vehicle is narrow, and the traction cables are not only rough and hard, but also transmit 1500V high voltage, which is easy to interfere with other equipment at the corners. During the operation of the vehicle, there is a risk of high voltage leakage caused by damage to the outer skin due to vibration. Therefore, the industry usually uses open thick-walled cloth-reinforced rubber tubes for protection.

[0003] Due to different vehicle models, thick-walled rubber tubes of different lengths are required to protect high-voltage cables, and the thick-walled rubber tubes need to be cut open in the axial direction. Currently, all rail vehicle manufacturers use manual cutting to operate. This method has the following problems: Since the wall of the thick-walled cloth-reinforced rubber tube is very thick, and the rubber material has a curtain interlayer, the manual use of wallpaper knives to cut it to the required length and the longitudinal cutting opening process is very inefficient, the cutting flatness is poor, and it is easy to slip, causing the operator to be cut by the wallpaper knife.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The core of the utility model is to provide an automatic cutting machine for cloth-reinforced rubber tubes, so as to improve the cutting efficiency of cloth-reinforced rubber tubes and enhance the safety during cutting.

[0043] Please refer to Figure 1-Figure 4 A cloth-reinforced rubber tube automatic cutting machine includes a frame 1, a limiting mechanism, a feeding mechanism 3 and a cutting mechanism 2. The limiting mechanism includes a plurality of limiting rollers 6 for limiting the rubber tube. The feeding mechanism 3 includes a clamping member 302 and a moving assembly 301 installed on the frame 1. The clamping member 302 is used to clamp the rubber tube. The moving assembly 301 is used to drive the clamping member 302 to move. The cutting mechanism 2 includes a first cutting knife 203 for cutting the rubber tube, and also includes a second cutting knife 4 for cutting the rubber tube along the axial direction.

[0044] When in use, the limit mechanism is installed on the frame 1, and the frame 1 is provided with basic structures for normal use of the machine, such as an electrical control cabinet, an air compressor, an operation controller, an equipment cabinet and a tool cabinet. Since the above structure is not a specific protection structure of the utility model, it is not repeated here. The unloading mechanism 3 includes a clamping member 302 and a moving assembly 301 installed on the frame 1. The clamping member 302 is used to clamp the rubber tube, and the moving assembly 301 is used to drive the clamping member 302 to move. Through the cooperation of the above clamping member 302 and the moving assembly 301, the rubber tube is driven to move, and the automatic unloading of the rubber tube is realized. Feeding and unloading, further, the cutting mechanism 2 includes a first cutting knife 203 for cutting the rubber tube, and also includes a second cutting knife 4 for cutting the rubber tube along the axial direction. Through the above-mentioned second cutting knife 4, the rubber tube is cut in the axial direction when the rubber tube is moved, and the rubber tube is cut under the action of the first cutting knife 203. That is to say, the cloth-reinforced rubber tube is automatically cut and split through the cooperation between the above-mentioned components, which greatly improves the cutting efficiency, improves the cutting smoothness, reduces the labor cost, and reduces the risk of cutting the cloth-reinforced rubber tube.

[0045] It should be noted that the embodiment of the utility model does not limit the specific installation method and position of the limiting roller 6. It only needs to be able to limit the cloth-reinforced rubber tube.

[0046] In addition, the embodiment of the utility model does not limit the specific structure of the clamping member 302 and the moving assembly 301. In some embodiments, the clamping member 302 can choose to use a clamping cylinder to achieve the clamping function of the rubber tube, and the moving assembly 301 can choose a cylinder or a screw 312.

[0047] In addition, the embodiment of the utility model does not limit the installation positions of the first cutting knife 203 and the second cutting knife 4. In some embodiments, the first cutting knife 203 is moved up and down by installing the moving assembly 301 to cut the rubber tube, and the second cutting knife 4 is installed on the frame 1 and located below the rubber tube to achieve the cutting operation of the rubber tube. At the same time, an adjustment mechanism is also provided to adjust the height of the second cutting knife 4 to achieve the cutting operation for rubber tubes of different sizes.

[0048] Please refer to Figure 1In order to further improve the smoothness of the rubber tube when it is cut, in some embodiments, it also includes an extrusion roller, which includes an extrusion roller 5 for flattening the rubber tube. There are two extrusion rollers 5. When the rubber tube passes between the two extrusion rollers 5, the rubber tube is flattened along the extension direction of the second cutting knife 4. That is to say, the extrusion rollers 5 are arranged in parallel with two axes, and the gap between the two extrusion rollers 5 is smaller than the diameter of the rubber tube. Therefore, when the rubber tube passes between the two extrusion rollers 5, the rubber tube is flattened. The flattened rubber tube is more conducive to cutting by the second cutting knife 4. At the same time, since the moving component 301 will drive the rubber tube to move, the extrusion rollers 5 will tighten the rubber tube at this time, which is conducive to improving the flatness of the rubber tube cut by the second cutting knife 4.

[0049] It should be noted that the embodiment of the utility model does not limit the way in which the two squeezing rollers 5 are installed on the frame 1. In some embodiments, a spacing adjustment structure can be provided to make the spacing between the two squeezing rollers 5 adjustable to adapt to the practical use of rubber tubes of more sizes, for example, a screw slider structure can be used. At the same time, anti-skid patterns can also be provided on the surfaces of the two squeezing rollers 5 to reduce the occurrence of slipping.

[0050] Please continue to refer to Figure 2 In some embodiments, a plurality of limiting rollers 6 are installed on the frame 1 in a crisscross pattern, that is, a plurality of limiting rollers 6 are installed in a crisscross pattern. When in use, the rubber tube passes through the gaps formed between the plurality of limiting rollers 6, thereby limiting the rubber tube and preventing it from warping during cutting.

[0051] It should be noted that the embodiment of the utility model does not limit the specific number of the limiting rollers 6. In some embodiments, at least four limiting rollers 6 are used.

[0052] Please refer to Figure 4In some embodiments, the unloading mechanism 3 further includes a first cylinder 303, and the clamping member 302 is two clamping plates. The first cylinder 303 can clamp or loosen the rubber tube by driving the two clamping plates to move closer or farther away. In other words, the two first cylinders 303 are used to drive the distance between the two clamping plates to be adjusted, thereby clamping or loosening the rubber tube. The moving component 301 is a motor 311, a screw 312 and a screw slide 313. The clamping member 302 is installed on the screw slide 313. When the motor 311 drives the screw 312 to rotate, the clamping member 302 drives the rubber tube to move. In other words, the two first cylinders 303 and the two clamping plates are installed. Installed on the screw slide 313, in the initial position, the screw slide 313 is located at the far right, at this time, the two clamping plates clamp the rubber tube, the motor 311 is started to rotate the screw 312, and the screw slide 313 moves to the set position along the axis of the screw 312, at this time the clamping plates are released, the motor 311 is reversed, and the screw slide 313 moves to the right, when it moves to the bottom of the first cutting knife 203, the clamping plates clamp the rubber tube, at this time the first cutting knife 203 cuts the rubber tube, after the cutting is completed, the clamping plates are released and the screw slide 313 moves to the initial position, repeating the above operations can realize the automatic cutting, splitting, loading and unloading of the rubber tube, which is more efficient.

[0053] It should be noted that the embodiment of the utility model does not limit the specific type of the motor 311. In some embodiments, it can adopt a stepper motor 311, a brushless motor 311, etc.

[0054] In addition, the embodiment of the utility model is not fixed to the first cylinder 303. In some embodiments, it can also use a hydraulic cylinder, etc., and can also use other structural methods that can drive the two clamping plates to move closer or farther away.

[0055] Please refer to Figure 1 In order to further prevent the rubber tube from warping when being cut by the first cutting knife 203, in some embodiments, a pressing roller 8 and an elastic component 9 are also included. The pressing roller 8 is used to press the rubber tube toward the second cutting knife 4 when the rubber tube passes through the second cutting knife 4, and the elastic component 9 is used to drive the pressing roller 8 to move toward the second cutting knife 4. That is, the pressing roller 8 is pressed down by the elastic component 9, so that the pressing roller 8 applies downward pressure to the rubber tube, thereby preventing the rubber tube from warping, which is beneficial to the cutting of the rubber tube and also improves the flatness of the rubber tube when it is cut by the second cutting knife 4.

[0056] It should be noted that the embodiment of the utility model does not specifically limit the elastic component 9. In some embodiments, the elastic component 9 can provide downward pressure for the pressing roller 8, for example, a spring or an elastic cylinder can be used.

[0057] Please refer to Figure 1 and Figure 2 In some embodiments, the cutting mechanism 2 also includes a second cylinder 201, and the first cutting knife 203 is installed at the protruding end of the second cylinder 201. When the second cylinder 201 drives the first cutting knife 203 to push toward the rubber tube, the rubber tube is cut off. In other words, the first cutting knife 203 is driven to cut off the rubber tube by the extension and contraction of the second cylinder 201.

[0058] It should be noted that the description of the second cylinder 201 in the embodiment of the utility model is not specifically limited. In some embodiments, other structures that can drive the first cutting knife 203 to move up and down can be adopted.

[0059] Please continue to refer to Figure 2 In order to further improve the efficiency of cutting the rubber tube, in some embodiments, the cutting mechanism 2 also includes a limit plate 202, which is installed on the protruding end of the first cylinder 303. The limit plate 202 has a U-shaped structure with an opening facing the rubber tube, and the first cutting knife 203 is installed on the limit plate 202. That is, through the limit plate 202 with a U-shaped structure, when the first cylinder 303 drives the limit plate 202 downward, the flattened rubber tube will be placed inside the U-shaped opening, thereby avoiding the problem of poor cutting efficiency caused by deformation of the rubber tube when the first cutting knife 203 cuts the rubber tube, and can also improve the flatness of the cut opening of the rubber tube by the first cutting knife 203.

[0060] Please refer to Figure 1 In order to further adapt to rubber tubes of different sizes and thicknesses, in some embodiments, it also includes: an adjusting plate 10, on which the second cutting knife 4 is installed, and the adjusting plate 10 is used to adjust the overlapping height between the second cutting knife 4 and the rubber tube. That is to say, the height of the second cutting knife 4 is adjusted by the adjusting plate 10, so that it can perform cutting operations on rubber tubes of different thicknesses, which is beneficial to improving the applicability of the device.

[0061] It should be noted that the description of the adjustment plate 10 in the embodiment of the utility model is not a limiting description. In some embodiments, other structural methods can be used to adjust the height of the second cutting knife 4, such as using bolts or telescopic rods.

[0062] Please refer to Figure 1 An infrared sensor 11 for detecting the rubber tube is provided between the squeezing roller and the limiting mechanism. That is to say, the infrared sensor 11 is provided to detect the rubber tube, and the infrared sensor 11 is connected to the operation controller of the equipment. When the infrared sensor 11 does not detect the rubber tube, the machine will not start, so as to avoid the danger caused by the misoperation of the cutting knife.

[0063] Please refer to Figure 1In order to prevent the rubber tube from moving in the opposite direction during the resetting process of the clamping member 302, in all embodiments, a one-way bearing is provided at the rotation connection between the squeezing roller 5 and the frame 1 to prevent the squeezing roller 5 from rotating in the opposite direction of the movement of the rubber tube. In other words, by providing a one-way bearing, the reverse movement of the rubber tube is avoided, which is beneficial to improve the control of the cutting length accuracy of the rubber tube.

[0064] When in use, the limiting mechanism is installed on the frame 1, and the frame 1 is provided with basic structures for normal use of the machine, such as an electrical control cabinet, an air compressor, an operating controller, an equipment cabinet and a tool cabinet. Since the above structure is not a specific protective structure of the utility model, it is not repeated here. The limiting mechanism includes a plurality of limiting rollers 6 for limiting the rubber tube to limit the rubber tube to avoid position deviation during cutting resulting in skewed cutting. The unloading mechanism 3 includes a clamping member 302 and a moving assembly 301 installed on the frame 1. The clamping member 302 is used to clamp the rubber tube, and the moving assembly 301 is used to drive the clamping member 302 to move. The cooperation of the parts 301 drives the rubber tube to move, thereby realizing automatic feeding and unloading of the rubber tube. Furthermore, the cutting mechanism 2 includes a first cutting knife 203 for cutting the rubber tube, and also includes a second cutting knife 4 for cutting the rubber tube along the axial direction. Through the above-mentioned second cutting knife 4, the rubber tube is cut in the axial direction when the rubber tube is moved, and the rubber tube is cut under the action of the first cutting knife 203. That is to say, the cloth-reinforced rubber tube is automatically cut and split through the cooperation between the above-mentioned parts, which greatly improves the cutting efficiency, improves the cutting smoothness, reduces the labor cost, and reduces the risk of cutting the cloth-reinforced rubber tube.

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
