Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a processing device for the outer ring of a triple-proof fabric air duct with a fixed-point cutting function. Background Art

[0002] The three-proof fabric duct is a pipe specially used for ventilation and exhaust, which is waterproof, oil-proof and corrosion-resistant. It is usually made of high-strength polyester fiber material, and the inner and outer layers are specially treated to effectively resist various harsh environments. Steel wire is wound around the outer ring to increase its strength. The three-proof fabric duct is waterproof, oil-proof, corrosion-resistant and high-temperature resistant. Compared with metal ducts, the three-proof fabric duct is lighter, has a certain degree of flexibility, and is easy to install and carry. Therefore, it has been widely used in many fields.

[0003] After the production of the three-proof cloth air duct is completed, it needs to be cut into several sections as required to facilitate subsequent packaging and transportation. However, the existing cutting method is generally to manually cut the steel wire of the outer ring of the air duct with a handheld hydraulic pliers, which has low work efficiency. In addition, when cutting the steel wire of the outer ring of the three-proof cloth air duct, if the cutting edge of the hydraulic pliers cannot be perpendicular to the steel wire, the cross section of the steel wire will form a sharp angle, which is easy to scratch the staff in the subsequent production process. Summary of the invention

[0004] The object of the present invention is to provide a processing device for the outer ring of a triple-proof fabric air duct with a fixed-point cutting function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the processing equipment for the outer ring of the triple-proof cloth air duct includes a frame, a supporting mechanism, a moving mechanism, a detecting mechanism, a cutting mechanism and a connecting seat, the supporting mechanism is tightly connected to the frame, the supporting mechanism is used to support the air duct, the moving mechanism is tightly connected to the frame, the connecting seat is tightly connected to the moving mechanism, the detecting mechanism and the cutting mechanism are tightly connected to the connecting seat respectively, the angle between the detecting mechanism and the cutting mechanism is ninety degrees, and the detecting mechanism is used to detect the inclination angle of the steel wire of the outer ring of the air duct.

[0006] The rack is placed on the ground to provide a stable working environment for each mechanism. After production, the three-proof cloth air duct needs to be cut into a suitable length to meet the subsequent packaging and transportation. The three-proof cloth air duct that needs to be cut is placed on the supporting mechanism. The supporting mechanism has the effect of restraining the three-proof cloth air duct to prevent it from shifting during the cutting operation. The mobile mechanism can drive the detection mechanism and the cutting mechanism to the position where it needs to be cut, so as to achieve fixed-point cutting of the three-proof cloth air duct. The connecting seat is used to connect the detection mechanism and the cutting mechanism. When the detection mechanism and the cutting mechanism are driven to the cutting position by the mobile mechanism, the detection mechanism first detects the inclination degree of the steel wire wrapped around the outer ring of the air duct, and adjusts the cutting mechanism according to the detection result. Then the mobile mechanism drives the connecting seat to rotate ninety degrees, rotates the cutting mechanism on one side to the cutting position, and cuts the steel wire.

[0007] The detection mechanism includes a detection cylinder, a guide seat, a cutter, a support spring and a varistor. The detection cylinder is tightly connected to the connecting seat, the output end of the detection cylinder is tightly connected to the guide seat, a guide groove is provided in the guide seat, the cutter is slidingly connected to the guide groove, one end of the support spring is tightly connected to the cutter, the other end of the support spring is tightly connected to the varistor, the varistor is tightly connected to the guide seat, the varistor is externally connected to a detection power supply, and the detection power supply and the varistor form a control system.

[0008] The detection cylinder is used to drive the guide seat to move toward the air duct, and then drive the cutter in the guide seat to insert into the cloth surface layer of the air duct, and then the support mechanism drives the air duct to rotate. As the air duct rotates, the cutter will cut the cloth surface layer of the air duct, so as to facilitate the subsequent cutting operation; and when the steel wire on the outer ring of the air duct contacts the cutter, because the steel wire is spirally wound on the outer ring of the air duct at a certain angle, when the cutter contacts the inclined steel wire, the steel wire will generate a force on the cutter. By decomposing this force, it can be seen that the greater the inclination angle of the steel wire, the greater the offset force of the steel wire on the cutter, and the more obvious the tendency of the cutter to deviate to one side along the guide groove, the cutter will deviate to one side, the support spring will be compressed, and the resistance value of the varistor will change due to the pressure, that is, the greater the inclination angle of the steel wire, the greater the pressure transmitted to the varistor, and the greater the pressure on the varistor, the smaller the resistance. The inclination angle of the steel wire can be known by detecting the change in the resistance value of the varistor through the control system. The smaller the resistance value of the varistor, the greater the inclination angle of the steel wire.

[0009] The cutter is divided into a tip portion, a blade portion and a connecting portion. The connecting portion is slidably connected with the guide groove. A pressure sensor is arranged on the connecting portion. The pressure sensor is electrically connected with the control system.

[0010] The force exerted by the steel wire on the outer ring of the air duct on the cutter is generated because the support mechanism drives the air duct to rotate. In order to ensure that the magnitude of this force remains consistent when testing different air ducts, when the control system detects that the pressure on the pressure sensor reaches the set value, it controls the support mechanism to stop, thereby ensuring that the force exerted by the steel wire on the outer ring of the air duct on the cutter remains consistent, so as to facilitate subsequent testing; the pointed part is used to pierce the cloth layer of the air duct so that the subsequent blade can cut the cloth layer; the connecting part can slide freely in the guide groove for testing.

[0011] The vertical cross section of the blade is rhombus-shaped.

[0012] The diamond-shaped cutting edge ensures sharpness and improves the processing efficiency when cutting the duct fabric surface layer.

[0013] The cutting mechanism includes an adjusting cylinder, a fixed disk, a rotating disk and a hydraulic clamp. The adjusting cylinder is tightly connected to the connecting seat, the output end of the adjusting cylinder is tightly connected to the fixed disk, the rotating disk is rotatably connected to the fixed disk, the hydraulic clamp is tightly connected to the rotating disk, and the hydraulic clamp is horizontally arranged.

[0014] When the detection mechanism detects the inclination angle of the steel wire, the control system controls the rotating disk to rotate a certain angle along the fixed disk, so that the horizontally arranged hydraulic pliers also rotate a corresponding angle, so that the cutting edge of the hydraulic pliers is perpendicular to the steel wire, which keeps the cross-section of the steel wire flat without sharp angles, thereby improving the safety of the air duct; after the angle adjustment of the hydraulic pliers is completed, the moving mechanism drives the connecting seat to rotate ninety degrees, so that the hydraulic pliers are facing the steel wire to be cut, and then the adjusting cylinder is started to drive the hydraulic pliers to approach the steel wire, and finally the hydraulic pliers are started to cut the steel wire.

[0015] An adjusting chamber and an arc groove are arranged in the fixed disk, and the cutting mechanism also includes a piston, a repelling magnet, an electromagnet and an arc spring. The piston is slidably connected to the adjusting chamber, the repelling magnet is firmly connected to the piston, the electromagnet is firmly connected to the inner wall of the adjusting chamber, the facing ends of the electromagnet and the repelling magnet are poles of the same name, the electromagnet is electrically connected to the control system, an arc slider and a rotating shaft are arranged on the rotating disk, the arc slider is slidably connected to the arc groove, the rotating shaft is rotatably connected to the fixed disk, one end of the arc spring is firmly connected to the arc slider, the other end of the arc spring is firmly connected to the inner wall of the arc groove, the adjusting chamber is communicated with the arc groove, and hydraulic oil is filled at the connection between the adjusting chamber and the arc groove.

[0016] In the initial state, under the support of the arc spring, the arc slider is in a horizontal state, that is, the hydraulic clamp on the rotating disk is in a horizontal state, and the rotating shaft on the rotating disk is inserted into the fixed disk as the rotation basis of the rotating disk; after the detection of the detection mechanism is completed, because the smaller the resistance of the varistor is, the larger the inclination angle of the steel wire is. When the control system detects the resistance of the varistor, the smaller the resistance of the varistor is, the larger the current transmitted to the electromagnet is. Under the action of like repulsion, the electromagnet will produce a repulsive force on the repelling magnet, thereby pushing the piston to move downward along the adjustment cavity, pressing the hydraulic oil in the adjustment cavity into the arc groove, and then driving the arc slider to slide upward along the arc groove, and the arc spring is compressed by force, so that the angle of the hydraulic clamp fixed on the rotating disk is adjusted; and the larger the inclination angle of the steel wire is, the larger the current transmitted to the electromagnet is, and the larger the angle of rotation of the rotating disk is, that is, the angle of the hydraulic clamp is automatically controlled according to the inclination angle of the steel wire wound around the outer ring of the air duct, so that the cutting edge of the hydraulic clamp is perpendicular to the steel wire, thereby ensuring the flatness of the cross section of the cut steel wire.

[0017] The supporting mechanism comprises a driving roller, a supporting roller and a driving motor. The driving roller and the supporting roller are rotationally connected to the frame. The driving motor is firmly connected to the frame. The output end of the driving motor is drivingly connected to the driving roller.

[0018] The drive motor is the main power source of the support mechanism. When the drive motor is started, it transmits torque to the drive roller, drives the drive roller to rotate on the frame, and then drives the air duct placed on the drive roller and the support roller to rotate, thereby facilitating detection by the detection mechanism.

[0019] The moving mechanism includes a fixed seat, a slide, a screw, a power motor, a column and a rotating motor. The fixed seat is tightly connected to the frame, a slide groove is provided on the fixed seat, the slide is slidably connected to the slide groove, the power motor is tightly connected to the fixed seat, the output end of the power motor is transmission connected to the screw rod, the screw rod is transmission connected to the slide, the column is tightly connected to the slide, the rotating motor is tightly connected to the column, and the output end of the rotating motor is tightly connected to the connecting seat.

[0020] When performing the cutting operation, the detection mechanism and the cutting mechanism are first driven to the working position through the moving mechanism. The power motor is the main power source of the moving mechanism. The power motor starts and transmits the torque to the screw rod, which then drives the screw rod to rotate, thereby driving the slide to slide along the slide groove on the fixed seat to the specified position. The column is used to provide an installation foundation for the rotating motor. When the detection mechanism is completed, the rotating motor starts and drives the connecting seat to rotate ninety degrees, so that the cutting mechanism is facing the air duct and cuts the steel wire on the outer ring of the air duct.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. The steel wire is spirally wound around the outer ring of the air duct at a certain angle, so when the cutter contacts the inclined steel wire, the steel wire will generate a force on the cutter. By decomposing this force, it can be seen that the greater the inclination angle of the steel wire, the greater the offset force of the steel wire on the cutter, and the more obvious the tendency of the cutter to deviate to one side along the guide groove. The cutter will deviate to one side, the supporting spring will be compressed, and the resistance value of the varistor will change due to the pressure. That is, the greater the inclination angle of the steel wire, the greater the pressure transmitted to the varistor, and the greater the pressure on the varistor, the smaller the resistance. The inclination angle of the steel wire can be known by detecting the change in the resistance value of the varistor through the control system. The smaller the resistance value of the varistor, the greater the inclination angle of the steel wire.

[0022] 2. After the control system detects the resistance value of the varistor, the smaller the resistance value of the varistor, the greater the current transmitted to the electromagnet. Under the effect of like-charge repulsion, the electromagnet will generate a repulsive force on the repelling magnet, thereby pushing the piston to move downward along the adjusting chamber, pressing the hydraulic oil in the adjusting chamber into the arc groove, and then driving the arc slider to slide upward along the arc groove. The arc spring is compressed by force, so that the angle of the hydraulic clamp fixed on the rotating disk is adjusted; and the greater the inclination angle of the steel wire, the greater the current transmitted to the electromagnet, and the greater the angle of rotation of the rotating disk, that is, the angle of the hydraulic clamp is automatically controlled according to the inclination angle of the steel wire wound on the outer ring of the air duct, so that the cutting edge of the hydraulic clamp is perpendicular to the steel wire, thereby ensuring the flatness of the cross section of the cut steel wire.

[0026] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution for processing equipment for the outer ring of a three-proof cloth air duct with a fixed-point cutting function. The processing equipment for the outer ring of the three-proof cloth air duct includes a frame 1, a supporting mechanism 2, a moving mechanism 3, a detecting mechanism 4, a cutting mechanism 5 and a connecting seat 6. The supporting mechanism 2 is tightly connected to the frame 1, and the supporting mechanism 2 is used to support the air duct. The moving mechanism 3 is tightly connected to the frame 1, and the connecting seat 6 is tightly connected to the moving mechanism 3. The detecting mechanism 4 and the cutting mechanism 5 are tightly connected to the connecting seat 6 respectively. The angle between the detecting mechanism 4 and the cutting mechanism 5 is ninety degrees. The detecting mechanism 4 is used to detect the inclination angle of the steel wire of the outer ring of the air duct.

[0027] The rack 1 is placed on the ground to provide a stable working environment for each mechanism. After production, the three-proof cloth air duct needs to be cut into a suitable length to meet the subsequent packaging and transportation. The three-proof cloth air duct that needs to be cut is placed on the supporting mechanism 2. The supporting mechanism 2 has the effect of restraining the three-proof cloth air duct to prevent it from deflecting during the cutting operation. The moving mechanism 3 can drive the detection mechanism 4 and the cutting mechanism 5 to the position where cutting is required to be performed, so as to achieve fixed-point cutting of the three-proof cloth air duct. The connecting seat 6 is used to connect the detection mechanism 4 and the cutting mechanism 5. When the detection mechanism 4 and the cutting mechanism 5 are driven to the cutting position by the moving mechanism, the detection mechanism 4 first detects the inclination degree of the steel wire wound around the outer ring of the air duct, and adjusts the cutting mechanism 5 according to the detection result. Then the moving mechanism 3 drives the connecting seat 6 to rotate ninety degrees, and rotates the cutting mechanism 5 on one side to the cutting position to cut the steel wire.

[0028] The detection mechanism 4 includes a detection cylinder 41, a guide seat 42, a cutter 43, a support spring 44 and a varistor 45.

[0029] The detection cylinder 41 is used to drive the guide seat 42 to move toward the air duct, and then drive the cutter 43 in the guide seat 42 to insert into the cloth surface layer of the air duct, and then the support mechanism 2 drives the air duct to rotate. As the air duct rotates, the cutter 43 will cut the cloth surface layer of the air duct, thereby facilitating the subsequent cutting operation; and when the steel wire on the outer ring of the air duct contacts the cutter 43, because the steel wire is spirally wound on the outer ring of the air duct at a certain angle, when the cutter 43 contacts the inclined steel wire, the steel wire will generate a force on the cutter 43. By decomposing this force, it can be seen that the steel wire The greater the inclination angle of the wire, the greater the offset force of the steel wire on the cutter 43, and the more obvious the tendency of the cutter 43 to deviate to one side along the guide groove 421. The cutter 43 will deviate to one side, and the support spring 44 will be compressed, and the resistance of the varistor 45 will change due to the pressure. That is, the greater the inclination angle of the steel wire, the greater the pressure transmitted to the varistor 45, and the greater the pressure received by the varistor 45, the smaller the resistance. The inclination angle of the steel wire can be obtained by detecting the change in the resistance value of the varistor 45 through the control system.

[0031] The force exerted by the steel wire on the outer ring of the air duct on the cutter 43 is generated because the support mechanism 2 drives the air duct to rotate. In order to ensure that the magnitude of this force remains consistent when testing different air ducts, when the control system detects that the pressure on the pressure sensor 46 reaches the set value, it controls the support mechanism 2 to stop, thereby ensuring that the magnitude of the force exerted by the steel wire on the outer ring of the air duct on the cutter 43 remains consistent, so as to facilitate subsequent testing; the pointed portion 431 is used to pierce the cloth layer of the air duct so that the subsequent blade 432 can cut the cloth layer; the connecting portion 433 can slide freely in the guide groove 421 for testing.

When the driving motor 23 is started, the torque is transmitted to the driving roller 21, driving the driving roller 21 to rotate on the frame 1, and then driving the air duct placed on the driving roller 21 and the supporting roller 22 to rotate, thereby facilitating the detection mechanism 4 to perform detection.

[0040] The moving mechanism 3 includes a fixed seat 31, a slide 32, a screw rod 33, a power motor 34, a column 35 and a rotating motor 36. The fixed seat 31 is tightly connected to the frame 1.

[0042] The working principle of the present invention is as follows: the support mechanism 2 drives the air duct to rotate, and as the air duct rotates, the cutter 43 will cut the cloth surface layer of the air duct, thereby facilitating the subsequent cutting operation; and when the steel wire on the outer ring of the air duct contacts the cutter 43, because the steel wire is spirally wound around the outer ring of the air duct at a certain angle, when the cutter 43 contacts the inclined steel wire, the steel wire will generate a force on the cutter 43. By decomposing this force, it can be seen that the greater the inclination angle of the steel wire, the greater the offset force of the steel wire on the cutter 43, and the more obvious the tendency of the cutter 43 to deviate to one side along the guide groove 421. The cutter 43 will deviate to one side, the support spring 44 is compressed, and the resistance value of the varistor 45 changes due to the pressure, that is, the greater the inclination angle of the steel wire, the greater the pressure transmitted to the varistor 45, and the greater the pressure on the varistor 45, the smaller the resistance. The varistor is detected by the control system The change in the resistance value of 45 can be used to know the inclination angle of the steel wire. The smaller the resistance value of the varistor 45, the larger the inclination angle of the steel wire. When the control system detects the resistance value of the varistor 45, the smaller the resistance value of the varistor 45, the larger the current transmitted to the electromagnet 57. Under the effect of like repulsion, the electromagnet 57 will generate a repulsive force on the repelling magnet 56, thereby pushing the piston 55 to move downward along the adjustment chamber 521, pressing the hydraulic oil in the adjustment chamber 521 into the arc groove 522, and then driving the arc slider 531 to slide upward along the arc groove 522. The arc spring is compressed by force, so that the angle of the hydraulic clamp 54 fixed on the rotating disk 53 is adjusted; and the larger the inclination angle of the steel wire, the larger the current transmitted to the electromagnet 57, and the larger the rotation angle of the rotating disk 53, that is, the angle of the hydraulic clamp 54 is automatically controlled according to the inclination angle of the steel wire wound around the outer ring of the air duct.
