Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a machine tool fault detection and shutdown device. Background Technology

[0002] Testing and packaging machines are devices used for automated product testing and packaging, widely used in electronics, food, pharmaceuticals, and many other industries. In modern industrial production, packaging machines serve as the final crucial step before products leave the factory, and their performance directly impacts packaging quality, production efficiency, and corporate image. With increasingly demanding packaging quality from consumers and rising labor costs, automated and intelligent packaging equipment has become a significant trend in the industry.

[0003] Typically, a testing packaging machine includes a machine base and a branding device. The branding device includes a drive unit and a soldering iron. The material to be branded is placed on the machine base, and the drive unit drives the soldering iron to move up and down on the machine base, causing the soldering iron to press down and brand the material, creating a brand mark on the material. This causes the materials to stick together and form a sealed packaging bag.

[0004] However, in actual operation, if the soldering iron presses down too frequently, such as exceeding the rated operating frequency of the equipment, it may cause machine overload or even equipment failure, affecting production efficiency and product yield.

[0005] Based on this, the present invention designs a machine tool fault detection and shutdown device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A detection device is provided on one side of the lifting rod. The detection device includes a connecting plate, a connecting disk, a gear, a laser emitter, and a receiver. The connecting plate is fixedly mounted on the lifting rod. A strip-shaped through hole is opened on the connecting plate. A slider is slidably mounted on the strip-shaped through hole. The slider is fixedly connected to the connecting disk. A protrusion is fixedly mounted on the side of the connecting disk. A gear is fixedly mounted on the base. The protrusion meshes with the gear. A notch is provided on the gear. The laser emitter and receiver are located on opposite sides of the gear. When the notch rotates to the connection line between the laser emitter and the laser receiver, the light signal emitted by the laser emitter is received by the receiver. The receiver is electrically connected to a control module. The control module is used to count the number of light signals received per minute and control the machine to stop and trigger an alarm when the number exceeds a set threshold.

[0007] By adopting the above technical solution, after the lifting rod extends and retracts once, it drives the connecting plate to rotate once, so that the protrusion and the gear mesh once, driving the gear to rotate. When the notch on the gear rotates to the space between the laser transmitter and the receiver, the control module determines the number of times the lifting rod has risen and fallen based on the light signal received by the receiver, so that each downward movement of the lifting rod is accurately recorded. Through the pre-set threshold, the control module can stop the machine in time and trigger an alarm when it detects that the machine is overloaded, thus realizing automated counting and shutdown control.

[0008] Preferably, the number of teeth of the gear and the meshing of the cam are set in a fixed ratio, and the gear rotates once when the lifting rod completes one extension and retraction movement.

[0009] By adopting the above technical solution, the counting logic is simplified, ensuring that the signal is triggered only once for each pressure, avoiding repeated counting, reducing the failure rate, and improving system stability.

[0010] Preferably, the gear includes gear teeth and a rotating plate. The rotating plate has several connecting holes on its side ring. A connecting rod is fixedly installed on the gear teeth and inserted into the connecting holes. The connecting plate also has several connecting holes on its side. The gear teeth are detachably installed on the connecting plate.

[0011] By adopting the above technical solution, the gear adopts a split design, which allows the gear teeth to be disassembled and installed through the connecting rod and connecting hole, making it easy to replace or repair the gear. The rotating plate can be adapted to gear teeth with different numbers of teeth, and the counting threshold can be flexibly adjusted.

[0012] Preferably, the connecting rod and the connecting hole are connected by magnetic means.

[0013] By adopting the above technical solutions, gear assemblies can be quickly disassembled and assembled, improving maintenance efficiency.

[0014] Preferably, the control module includes a counter for recording the number of optical signals received by the receiver per minute.

[0015] By adopting the above technical solution, the number of times the pressure is applied per minute is recorded to ensure that the production rhythm is controllable.

[0016] Preferably, the control module includes an audible and visual alarm for issuing an alarm when the machine stops.

[0017] By adopting the above technical solutions, multi-sensory warnings (sound + light) ensure that operators can detect abnormalities in a timely manner, making it suitable for noisy industrial environments and improving the effectiveness of alarms.

[0018] Preferably, the control module further includes a delayed reset function.

[0019] By adopting the above technical solution, forced manual intervention is required to prevent automatic resumption of operation when the fault has not been resolved.

[0020] In summary, this application has the following beneficial technical effects: After the lifting rod extends and retracts once, it drives the connecting plate to rotate once, causing the protrusion to mesh with the gear once, driving the gear to rotate. When the notch on the gear rotates between the laser transmitter and the receiver, the control module determines the number of times the lifting rod has risen and fallen based on the light signal received by the receiver, so that each downward movement of the lifting rod is accurately recorded. Through the pre-set threshold, the control module can stop the machine and trigger an alarm in time when it detects that the machine is overloaded, thus realizing automated counting and shutdown control.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] A machine fault detection and shutdown device includes a branding device, which comprises a base 1, a lifting rod 2, a mounting platform 3, and a soldering iron 5. Two lifting rods 2 are symmetrically arranged on the base 1. The mounting platform 3 is fixedly positioned above the lifting rods 2, and the soldering iron 5 is fixedly positioned at the bottom of the mounting platform 3. A cylinder 4 for driving the extension and retraction of the lifting rods 2 is mounted on the mounting platform 3. A detection device is located on one side of the lifting rod 2. The detection device includes a connecting plate 6, a connecting disk 8, a gear 13, a laser emitter 11, and a receiver 16. The connecting plate 6 is fixedly positioned on the lifting rod 2 and has a strip-shaped through hole 7. A slider 10 is slidably mounted on the strip-shaped through hole 7 and is fixedly connected to the connecting disk 8. A protrusion 9 is fixedly mounted on the side of the connecting disk 8. The gear 13 is fixedly mounted on the base 1, and the protrusion 9 meshes with the gear 13. A notch 14 is provided on the gear 13. The laser emitter 11 and the receiver 16 are located on opposite sides of the gear 13, and the receiver 16 is electrically connected to a control module 15.

[0027] In use, the branding device operates, and the cylinder 4 drives the lifting rod 2 to extend and retract, causing the branding iron 5 to press down and then rise, completing one branding cycle for packaging. During the lifting and lowering process, the lifting rod 2 drives the connecting plate 6 to move downward and then rise, causing the slider 10 to begin sliding in the strip-shaped through hole 7. The connecting plate 8 rotates accordingly. When the lifting rod 2 completes one lifting and lowering cycle, the connecting plate 8 completes one revolution. When the connecting plate 8 rotates, the protrusion 9 rotates to mesh with the tooth groove on the gear 13, causing the gear 13 to rotate one tooth 19 arc. When the notch 14 on the gear 13 rotates between the laser emitter 11 and the receiver 16, the receiver 16 receives the light signal emitted by the laser emitter 11. The receiver 16 transmits a signal to the control module 15, which counts the number of light signals received per minute and controls the machine to stop and triggers an alarm when the number exceeds a set threshold.

[0028] The number of teeth of gear 13 and the meshing of protrusion 9 are set in a fixed ratio. Gear 13 includes gear teeth 19 and rotating plate 20. The side of rotating plate 20 is provided with several connecting holes 18. A connecting rod 17 is fixedly installed on gear teeth 19 and is inserted into the connecting hole 18. The side of connecting plate 8 is also provided with several connecting holes 18. Gear teeth 19 can be detachably installed on connecting plate 8. A magnetic block 1 is provided on connecting rod 17 and a magnetic block 2 is provided in the connecting hole 18.

[0029] By disassembling and assembling the tooth groove on gear 13, the number of teeth 19 on gear 13 can be quickly changed, which facilitates the adjustment of the number of times the branding device presses down per minute. The removed teeth 19 can be directly inserted into the connecting plate 8 and fit into the protrusion 9 on the connecting plate 8, so that the width of the protrusion 9 plus the teeth 19 can adapt to the width of the adjusted tooth groove, ensuring that after the connecting plate 8 rotates one revolution, gear 13 can rotate one tooth 19 angle.

[0030] The control module 15 includes a counter, an audible and visual alarm 12, and a controller. The controller is electrically connected to the cylinder 4. The counter is used to record the number of light signals received by the receiver 16 per minute and then transmits the recorded data to the controller. When the set threshold is exceeded, the controller controls the audible and visual alarm 12 to emit an alarm sound and light and controls the cylinder 4 to stop running. The control module 15 also includes a delayed reset function to force manual intervention and prevent automatic resumption of operation if the fault is not eliminated.

[0031] The implementation principle of this embodiment is as follows: When in use, the branding device operates, and the cylinder 4 drives the lifting rod 2 to extend and retract, so that the branding iron 5 is pressed down and then raised, completing one branding of the packaging. During the lifting and lowering process, the lifting rod 2 drives the connecting plate 6 to move downward and then rise, so that the slider 10 begins to slide in the strip-shaped through hole 7, and the connecting plate 8 rotates accordingly. When the lifting rod 2 completes one lifting and lowering, the connecting plate 8 completes one revolution. When the connecting plate 8 rotates, the protrusion 9 rotates to mesh with the tooth groove on the gear 13, so that the gear 13 rotates one tooth 19 arc. When the notch 14 on the gear 13 rotates between the laser emitter 11 and the receiver 16, the receiver 16 receives the light signal emitted by the laser emitter 11 and receives it. The receiver 16 transmits the signal to the control module 15. The counter is used to record the number of light signals received by the receiver 16 per minute, and then transmits the recorded data to the controller. When the set threshold is exceeded, the controller controls the sound and light alarm 12 to emit an alarm sound and light and controls the cylinder 4 to stop running.
