Detailed Description
The utility model is further described below with reference to the accompanying drawings:
Referring to fig. 1-2: the automatic detection device for the clamping materials in the embodiment comprises a fixed plate 1, a movable plate 2 and a travel switch 3, wherein the travel switch 3 is fixedly arranged on the fixed plate 1 or the movable plate 2 and is positioned between the fixed plate 1 and the movable plate 2, a guide pillar 4 is fixedly arranged on the fixed plate 1, the guide pillar 4 is in sliding connection with a guide sleeve 5, the guide sleeve 5 is fixedly arranged on the movable plate 2, a bearing seat 6 is fixedly arranged on the right side of the movable plate 2, a rotating shaft 7 is rotatably arranged on the bearing seat 6 through a bearing, and a stable support and a stable rotating point are provided for the rotating shaft, so that the rotating shaft can still keep flexible rotation under the condition of stress, and smooth and efficient conveying of a material belt is ensured. A pressure spring 8 is arranged between the left side of the movable plate 2 and the fixed plate 1, the pressure spring 8 is fixedly arranged on the guide post 4, the travel switch 3 is electrically connected to an automatic motor start-stop circuit of the feeder 9 to control the power on-off of the feeder 9, and the feeder 9 is used for conveying a material belt 11 which is discharged from a damping discharge disc 10 and bypasses the transition of the rotating shaft 7. The design of the rotating shaft enables the material belt to smoothly transition from the damping discharging disc to the feeder, ensures the continuity and stability of material belt conveying, and simultaneously reduces the abrasion and damage possibly occurring in the transition process of the material belt. The travel switch plays a vital safety protection role in the system, and when the stress of the rotating shaft is detected to be too large, the travel switch can be rapidly disconnected, so that the scram of the feeder is realized, thereby preventing possible equipment damage and production accidents and improving the safety of the whole system.
The working principle of the automatic material clamping detection device is that the automatic monitoring and control of the material clamping condition of the feeder are realized through a series of carefully designed mechanical and electrical components. In a normal operating state, when the material belt 11 on the damping discharge tray 10 is knotted or the material cylinder cannot rotate normally, the abnormal state can cause the rotating shaft 7 to receive abnormal tensile force. At this time, the movable plate 2 is kept in place by being supported by the compression spring 8, and the sliding connection between the guide post 4 and the guide sleeve 5 allows the movable plate 2 to displace when being stressed. As the tension of the rotating shaft 7 increases, the bearing fixing plate (i.e., the movable plate 2) is pushed by the compression spring 8 until touching the travel switch 3. The contact of the travel switch 3 is opened immediately, so that the motor of the feeder 9 is automatically started to cut off the power supply circuit, and emergency stop control is realized. The design ensures that once the material is blocked in the material belt conveying process, the device can respond quickly, and further equipment damage and potential production safety accidents are prevented through an emergency stop mechanism. The pressure spring provides necessary buffering and supporting functions, when the material belt encounters resistance or other abnormal conditions in the conveying process, the pressure spring can absorb and buffer impact forces, the movable plate and other components are protected from being damaged, and meanwhile smooth transition of the material belt is ensured.
The automatic start-stop circuit of the motor is a common technical means in the field. The automatic starting and stopping circuit of the motor is started by the control switch, so that the contactor is attracted, and the motor power supply is switched on, so that the starting is realized. In the operation process, the travel switch monitors the mechanical position, and when the travel switch reaches a preset position, the travel switch is triggered to send a stop signal, so that the contactor is released, and the motor is powered off and stopped. The circuit not only realizes the basic start-stop control of the motor, but also increases the accuracy and the safety of the system through the position detection function of the travel switch.
The fixed plate 1, the movable plate 2 and the travel switch 3 are at least provided with two groups. Such a design means that the automatic jamming detection arrangement is structurally more redundant and reliable. By arranging a plurality of groups of identical components, the device can monitor the conveying state of the material belt 11 at different positions, thereby increasing the coverage range and the accuracy of detection. In actual operation, if one group of detection devices fails for some reasons or needs maintenance, the other groups of detection devices can still continue to work, so that the normal operation and safety of the whole feeding system are ensured. The multiple detection mechanism effectively reduces risks brought by a single fault point and improves the fault tolerance of the whole system. In addition, the setting of multiunit detection device can also make the material area 11 in the pay-off in-process any position all obtain timely control, in case detect card material or other abnormal conditions, corresponding travel switch 3 can act immediately, triggers the scram protection to ensure equipment and operating personnel's safety.
The lower part of the movable plate 2 is connected with a supporting plate 12 in a sliding way, and the supporting plate 12 is fixedly connected with the fixed plate 1. The supporting plate is used for stabilizing the movable plate, so that the movable plate is kept in a horizontal state in the working process, and inclination caused by rotation of the guide post is prevented, and the stability and reliability of the whole detection device are ensured.
The feeder 9 comprises a feeding frame, an upper pressing wheel, a lower pressing wheel and a motor, wherein the upper pressing wheel and the lower pressing wheel are rotatably arranged on the feeding frame, a material belt 11 is arranged between the upper pressing wheel and the lower pressing wheel, one end of the upper pressing wheel or one end of the lower pressing wheel is connected with the motor, and the motor is electrically connected with an automatic power-on/off circuit of the motor. The fixing plate is used as a key part connected with the feeder frame, provides a stable supporting foundation for the whole device, and ensures the stability and durability of the device in the operation process.
The structural design of the feeder 9 is designed to achieve efficient transport and control of the strip 11. The feeding frame serves as a base structure of the whole feeder, providing a stable support and enough space to accommodate the running track of the upper and lower pinch rollers and the material tape 11. The upper and lower pinch rollers are designed to provide the necessary pressure and guidance as the strip 11 passes, ensuring that the strip can pass through the feeder smoothly and accurately and be transferred to the next job.
During operation of the feeder 9, the strip 11 first comes out of the damping discharge tray 10 and then bypasses the spindle 7, passing between the upper pinch roller and the lower pinch roller. In the process, the upper pressing wheel and the lower pressing wheel are driven by a motor, one end of the motor is connected with the upper pressing wheel or the lower pressing wheel, and the pressing wheel is driven to rotate through the rotation of the motor, so that the conveying of a material belt is realized.
The design of the motor is a power source of the whole feeding system, and the motor is electrically connected with an automatic starting and stopping circuit of the motor, which means that the starting and stopping of the motor can be accurately controlled through an electric control system. When the automatic detection device for clamping materials detects abnormal conditions, such as clamping of the material belt 11 or overlarge pulling force, the travel switch 3 can trigger a sudden stop signal to cut off the power supply of the motor, so that the motor stops running, and further damage of the material belt and possible safety accidents are avoided.
The right end of the guide post 4 is provided with a pin hole, and a penetrating pin 13 is fixedly arranged on the pin hole. The existence of the penetrating pin ensures that the guide sleeve 5 and the movable plate 2 cannot slide out of the guide post 4 due to the jacking force of the pressure spring 8, thereby ensuring the stability and reliability of the whole device.
