Description

Technical Field

[0001] This utility model relates to the field of correction equipment technology, and in particular to an automatic material shortage alarm correction device. Background Technology

[0002] When processing and cutting self-sealing plastic bags, it is necessary to maintain the position of the plastic bags to prevent them from shifting. Usually, a correction sensor is used to monitor the specific position of the plastic bags. Current correction sensors are mainly fixed to both sides of the cutting device using screws, bolts and other connectors. The position is fixed, which makes it difficult to install and disassemble. In addition, some wide paper bags may cover the installation position of the correction sensor, making it impossible for it to monitor in its original position.

[0003] The prior art disclosure number CN214495100U discloses an automatic material shortage alarm and correction device, including a workbench with an active rotating groove on the top and a baffle plate inside the active rotating groove. This automatic material shortage alarm and correction device, through the arrangement of a drive screw, a first drive block, a first carrier plate, a second drive block, a guide rod, a mounting groove, a mounting plate, a pull basket, a connecting rod, a push block, a locking rod, a lock hole, a spring, a limit rod, a pull handle, and a second carrier plate, allows the drive screw to be rotated so that the first and second carrier plates move closer and further apart, thereby adjusting the position of the two mounting grooves. The mounting grooves are used to install correction sensors, thus adjusting the position of the correction sensors. Pulling the two pull handles outward solves the problem that current correction sensors are difficult to install and remove, and that some wide paper bags may cover the installation position of the correction sensors, preventing them from monitoring in their original position.

[0004] However, in actual high-speed and continuous production operations, this solution still has obvious defects: it lacks an effective locking mechanism, and the drive screw is prone to loosening and self-rotation in the environment of continuous equipment vibration, which causes the adjusted sensor position to shift, seriously affecting the detection accuracy and product quality stability; the installation of individual sensors is still inconvenient. Although the mounting plate is easy to disassemble and assemble as a whole, the main body of the correction sensor still needs to be fixed to the mounting plate by bolts and other components. When replacing, calibrating or maintaining the sensor individually, the operation is still not convenient enough. Utility Model Content

[0005] The purpose of this invention is to provide an automatic material shortage alarm and correction device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution, which includes a main work platform, a pair of support plates symmetrically arranged at the bottom of the main work platform, an installation groove in the middle of the top of the main work platform, mounting frames symmetrically arranged on both sides of the main work platform, an adjustment component on the main work platform, a pair of quick-release components symmetrically arranged on the adjustment component, and an auxiliary installation component on each quick-release component.

[0007] In a preferred embodiment of this invention, the adjusting assembly includes a bidirectional lead screw, which is movably mounted in a mounting slot via a pair of bearing seats. A self-locking motor is mounted on one of the mounting brackets, and the transmission end of the self-locking motor is connected to one end of the bidirectional lead screw via a coupling. A pair of adjusting plates are symmetrically arranged on the main worktable, and a drive plate is mounted at the bottom of each adjusting plate. The drive plate is mounted in the mounting slot and has a nut threaded onto it.

[0008] As a preferred embodiment of this utility model, a pair of sliding grooves are symmetrically provided on the main work platform, and a slider is provided at the bottom of each adjustment plate corresponding to the position of the sliding groove, and the slider is movably disposed in the sliding groove.

[0009] As a preferred embodiment of this utility model, the quick assembly / disassembly assembly includes an assembly shell disposed on an adjustment plate, wherein several magnetic blocks are disposed on the inner top and inner bottom surfaces of the assembly shell, and a conduit is disposed on the upper back of the assembly shell.

[0010] As a preferred embodiment of this utility model, the auxiliary installation component includes several suction cups disposed on the inner wall of the mounting shell, each suction cup having a connecting pipe at its tail end, the connecting pipe passing through the mounting shell, and the tail ends of several connecting pipes simultaneously connected to a diversion pipe, the diversion pipe having a flexible hose, the other end of the flexible hose being disposed on a miniature negative pressure vacuum pump, the miniature negative pressure vacuum pump being disposed on the top of the mounting frame.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: The adjustment component of this utility model is driven by a self-locking motor to drive a bidirectional lead screw. The self-locking motor has a power-off self-locking function, which can effectively resist the vibration generated by long-term operation of the equipment and prevent the sensor position from shifting due to vibration rotation of the drive screw. With the guide and stabilizing structure of the slide and slider, it ensures that the sensor position is accurately locked after adjustment and always stays in the optimal monitoring position, which significantly improves the accuracy of monitoring the edge position of the plastic bag and ensures stable cutting processing quality.

[0012] This invention utilizes a combination of quick-assembly and disassembly components and auxiliary installation components. The magnetic block enables the sensor to be initially and quickly positioned, while the suction cup driven by the miniature negative pressure vacuum pump forms a secondary stable adsorption. Without the need for traditional connectors such as bolts, installation is completed quickly with double fixation. Disassembly only requires turning off the vacuum pump and removing the sensor, which greatly simplifies the operation process, reduces the time cost of sensor replacement and calibration, and improves equipment maintenance efficiency.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figures 1-5 As shown, the present invention proposes an automatic material shortage alarm and correction device, which includes a main work platform 1. A pair of support plates 10 are symmetrically fixed at the bottom of the main work platform 1 to provide stable support. An installation groove 11 is opened in the center of the top of the main work platform 1, and mounting brackets 12 are symmetrically arranged on both sides of it. The main worktable 1 is equipped with an adjustment component 2, and a pair of quick-release components 3 are symmetrically mounted on the adjustment component 2. Each quick-release component 3 is equipped with an auxiliary installation component 4. The adjustment assembly 2 is used to adjust the position of the correction sensor 5. It includes a bidirectional lead screw 20, which is movably installed in the mounting groove 11 through a pair of bearing seats 21. A self-locking motor 22 is fixedly installed on one of the mounting brackets 12. Its output shaft is connected to one end of the bidirectional lead screw 20 through a coupling 23. Two adjustment plates 24 are symmetrically arranged on the main worktable 1. A drive plate 25 is fixedly connected to the bottom of the adjustment plate 24. The drive plate 25 extends into the mounting groove 11 and is fixedly provided with a nut 26. The nut 26 is threadedly engaged with the bidirectional lead screw 20 to form a lead screw nut transmission pair. To ensure that the adjustment plate 24 moves smoothly, a pair of sliding grooves 13 are symmetrically opened on the main worktable 1. A slider 27 is provided at the corresponding position at the bottom of the adjustment plate 24. The slider 27 slides in the sliding groove 13. The quick-release assembly 3 is used to quickly install and remove the correction sensor 5. It includes a mounting shell 30 fixedly mounted on the adjustment plate 24 for housing the correction sensor 5. Multiple magnetic blocks 31 are embedded on the inner top and inner bottom surfaces of the mounting shell 30, and a conduit 32 is opened on the upper back of the shell for the sensor cable to pass through. The auxiliary mounting assembly 4 is used to enhance the stability of the sensor mounting. It includes multiple suction cups 40 fixed to the inner wall of the mounting housing 30. Each suction cup 40 is connected to a connecting pipe 41. The connecting pipe 41 extends through the mounting housing 30 to the outside. The outer ends of all the connecting pipes 41 are connected to a diverter pipe 42. A flexible hose 43 is connected to the diverter pipe 42. The other end of the flexible hose 43 is connected to a miniature negative pressure vacuum pump 44, which is fixedly mounted on the top of the mounting bracket 12.

[0017] During the sensor installation and fixing stage, the two correction sensors 5 are first placed into the two mounting shells 30 respectively. The magnetic force generated by the magnetic block 31 inside the mounting shell 30 is used for initial adsorption and positioning. Then, ensure that the back of the sensor is in close contact with the suction cup 40 on the inner wall of the mounting shell 30. Then, start the miniature negative pressure vacuum pump 44. The miniature negative pressure vacuum pump 44 draws air from the suction cup 40 through the hose 43, the diverter 42 and the connecting pipe 41, so that the suction cup 40 generates negative pressure suction, which together with the magnetic block 31 achieves double fixing of the sensor. During the width adjustment stage, according to the width of the material to be processed, the controller sends a forward or reverse rotation command to the self-locking motor 22. The self-locking motor 22 drives the bidirectional lead screw 20 to rotate. Through the threaded engagement between the lead screw nut 26 and the bidirectional lead screw 20, the two drive plates 25 and the adjustment plate 24 on both sides move in opposite directions along the slide groove 13. After the adjustment is in place, the self-locking function of the self-locking motor 22 can prevent it from rotating on its own when the equipment vibrates, thereby locking the sensor position. During the monitoring and alarm phase, after the device is started, the two correction sensors 5 monitor the edge position of the material in real time. When the material is detected to be deviating or interrupted, the sensor will feed the signal back to the control system. After receiving the signal, the control system will immediately issue an alarm and can link the material interruption device to perform corresponding operations.
