Description
Technical Field
[0001] The utility model relates to the technical field of cigarette machinery, and more specifically, particularly relates to an overload protection device for a cigarette strip push plate of a cigarette packaging device. Background Art
[0002] The YB95 (CV) strip transparent paper packaging machine, as a device widely used in the tobacco production field, is designed to efficiently and stably complete the further encapsulation process of cigarette strips (usually a set of already packaged cigarette sticks), that is, to wrap transparent paper on the outer layer to increase the aesthetic degree and protectiveness. In the entire technological process of the YB95 (CV) strip transparent paper packaging machine, it usually includes a cigarette strip output step, that is, the cigarette strip wrapped with transparent paper needs to be conveyed to the next process or collection area, and this step involves a cigarette strip output push plate that performs a horizontal reciprocating motion controlled by a cam. The push plate performs a horizontal reciprocating motion under the action of the cam, that is, first pushes the cigarette strip forward to make it leave the second lifter and enter the cigarette strip output channel, and then returns to the initial position to prepare for the next push.
[0003] During the operation of the device, due to equipment failures, poor cigarette strip forming and failure to rise in place, etc., cigarette clamping occurs during the process of pushing cigarettes horizontally. Since the equipment lacks safety overload detection and overload devices, the equipment will continue to operate, resulting in a large number of cigarette strips being damaged, and it is necessary to manually stop the machine, or the equipment will automatically stop only when the deformed cigarette strips affect the normal operation of other parts of the equipment, which poses potential hazards to safety, production consumption, and equipment damage. Summary of the Utility Model
[0004] An object of the utility model is to provide an overload protection device for a cigarette strip push plate of a cigarette packaging device to solve the above-mentioned problems that due to the lack of safety overload detection and overload devices in the equipment, the equipment will continue to operate, resulting in a large number of cigarette strips being damaged, and it is necessary to manually stop the machine, or the equipment will automatically stop only when the deformed cigarette strips affect the normal operation of other parts of the equipment, which poses potential hazards to safety, production consumption, and equipment damage.

[0031] The present utility model provides an embodiment of an overloading protection device for a cigarette bar push plate of a cigarette packaging equipment. Specifically, as Figure 1 shown, it includes:
[0032] The cigarette pushing plate 2 is fixedly connected to the guide rod 3 by screws; ensuring that the relative position between the two remains unchanged during the cigarette pushing process.
[0033] The guide rod 3 passes through the corresponding hole on the guide rod seat 4 and can slide freely in the hole; one end of the guide rod 3 is fixedly connected to the cigarette pushing plate 2, and the other end of the guide rod 3 is fixedly connected to the metal sheet 7 by screws; the guide rod 3 provides guidance and support for the cigarette pushing plate 2 to ensure that it can move smoothly along a predetermined path. The guide rod 3 is designed to be cylindrical. The guide rod 3 passes through the corresponding hole on the guide rod seat 4, and the inner wall of the hole is smooth to reduce friction and allow the guide rod 3 to slide freely in the hole.
[0034] The guide rod seat 4 has a hole inside for the guide rod 3 to pass through, and a permanent magnet 6 is fixedly connected (such as by welding, etc.) at the middle position of the guide rod seat 4; there is a hole inside the guide rod seat 4 that matches the guide rod 3, and the diameter of the hole is slightly larger than the outer diameter of the guide rod to allow the guide rod to slide freely. The magnetic pole of the permanent magnet 6 faces the metal sheet 7 and is used to trigger the protection mechanism through magnetic force during overload.
[0035] The proximity switch 5 is fixed to one end of the guide rod seat 4;
[0036] The metal sheet 7 is fixedly connected to the other end of the guide rod 3 by screws; the metal sheet 7 serves as the triggering component for overload protection and forms a magnetic force pair with the permanent magnet 6. When the cigarette pushing plate 2 is subjected to an overload resistance, the metal sheet 7 moves together with the guide rod 3, and the distance from the permanent magnet 6 changes.
[0037] The working end (i.e., the sensing surface) of the proximity switch 5 is aligned with the metal sheet 7 to ensure that the position change of the metal sheet 7 can be accurately sensed.
[0038] In the embodiment of the present utility model, two guide rods 3 are provided, and the guide rod seat 4 is correspondingly provided with a first hole and a second hole, and the two guide rods 3 respectively pass through the first hole and the second hole on the guide rod seat 4.
[0039] In the embodiment of the present utility model, at the middle position between the first hole and the second hole, a third hole is provided, and a permanent magnet 6 is fixedly connected in the third hole. The permanent magnet 6 is cylindrical. The permanent magnet 6 is fixed at the middle position of the guide rod seat 4 to ensure the correct relative position relationship with the metal sheet 7 in case of overload.
[0040] In the embodiment of the present utility model, the end face of the permanent magnet 6 is flush with one side plane of the guide rod seat 4. Since the end face of the permanent magnet 6 is flush with one side plane of the guide rod seat 4, the magnetic field lines are relatively evenly distributed in the gap between the permanent magnet 6 and the guide rod seat 4, which helps the metal sheet 7 to be stably adsorbed on the guide rod seat 4 under the action of magnetic force, forming a firm connection.
[0041] In the embodiment of the present utility model, the proximity switch 5 is electrically connected to the host control system. The proximity switch 5 is electrically connected to the host control system through wires and transmits the detected overload signal to the control circuit to trigger corresponding protection actions.
[0042] In the embodiment of the present utility model, following the sliding of the guide rod 3 in the guide rod seat 4, the metal sheet 7 approaches or moves away from the permanent magnet 6 to trigger the proximity switch 5.
[0043] In the embodiment of the present utility model, a connecting rod 1 is connected above the guide rod seat 4; the connecting rod 1 is a key component connecting the cigarette pushing mechanism and the host drive system, which can transmit the power of the host to the cigarette pushing plate 2 and drive it to perform horizontal reciprocating motion, thereby completing the cigarette pushing action.
[0044] In the embodiment of the present utility model, a dust-proof cover is installed outside the guide rod seat 4. The dust-proof cover can effectively prevent pollutants such as dust, tobacco debris, and grease in the air from entering the inside of the guide rod seat 4. If these pollutants accumulate on the surface of the guide rod seat 4 or the permanent magnet 6, it will affect the adsorption force of the permanent magnet 6 and even cause the metal sheet 7 to be unable to be magnetically attracted or disengaged normally. By reducing the erosion of pollutants on the guide rod seat 4 and its internal components, the dust-proof cover helps to extend the service life of these components and reduce the failure rate caused by wear or corrosion.
[0045] In the embodiment of the present utility model, the metal sheet is an iron sheet or a steel sheet.
[0046] Under normal conditions, the metal sheet 7 is magnetically attracted to the guide rod seat 4 by the permanent magnet 6 and is equivalent to being connected to the guide rod seat 4 as a fixed part (as Figure 1 shown in the left state), ensuring the relative position relationship among the cigarette pushing plate 2, the guide rod 3, the metal sheet 7, and the guide rod seat 4 is stable without overload resistance. When the cigarette packaging equipment is running, if the cigarette pushing plate 2 encounters abnormal resistance (such as cigarette bar blockage, mechanical failure, etc.) and cannot continue to smoothly push the cigarette bar, if the equipment still tries to push the cigarette pushing plate 2 forward through the motor or other power sources, then this overload force will be transmitted to the metal sheet 7 through the guide rod 3. As the overload resistance increases, the forward thrust received by the metal sheet 7 gradually increases until this thrust overcomes the magnetic attraction force of the permanent magnet 6 on the metal sheet 7. Once the metal sheet 7 overcomes the magnetic force, it will disengage from the guide rod seat 4 and is no longer restricted by the magnetic force. When the metal sheet 7 disengages from the guide rod seat 4 and moves away from the working end of the proximity switch 5, the magnetic field proximity sensed by the proximity switch 5 changes. The proximity switch 5 immediately converts this change into an electrical signal and transmits it to the host control system of the cigarette packaging equipment through the circuit. After receiving the shutdown signal sent by the proximity switch 5, the host control system will immediately perform corresponding protection actions, such as cutting off the power supply of the motor and stopping the further movement of the equipment, to prevent the equipment from continuing to operate in an overloaded state and causing more serious damage or safety accidents. At the same time, the host control system will also display corresponding fault prompt information on the display screen of the equipment to inform the operator that the current equipment is in a shutdown state.
[0047] After the operator understands the cause of the fault and eliminates the fault (such as clearing the blocked cigarette rod, repairing mechanical faults, etc.), it is necessary to manually push the cigarette pushing plate 2 to make it return to the normal position. When the cigarette pushing plate 2 drives the guide rod 3 and the metal sheet 7 to move together, the metal sheet 7 will approach the permanent magnet 6 again and be re-attracted by the magnetic force, and the metal sheet 7 is re-connected to the guide rod seat 4 to form a solid part, and the device returns to a state where it can work normally.
[0048] The utility model effectively prevents the cigarette pushing plate 2 and its connecting components from continuing to work under overload conditions, thereby avoiding possible damage caused by excessive stress. It ensures that the device can quickly stop running when a fault is detected, preventing the further expansion of the fault and potential safety risks. The stop signal not only stops the device from working, but also prompts the corresponding fault information on the main machine display screen. After the fault is cleared and the device returns to normal, the operator only needs to simply push the cigarette pushing plate 2 to make the metal sheet 7 be magnetically attracted to the guide rod seat 4 by the permanent magnet 6 again. This easy-to-recover design reduces the repair time and workload, and improves the overall reliability and production efficiency of the device.
[0049] The structure, features and function effects of the utility model have been described in detail based on the embodiments shown in the drawings above. However, the above are only the preferred embodiments of the utility model. It should be noted that for the technical features involved in the above embodiments and their preferred modes, those skilled in the art can reasonably combine and match them into a variety of equivalent solutions without departing from and changing the design concept and technical effects of the utility model; Therefore, the scope of implementation of the utility model is not limited by the drawings shown. Any changes made in accordance with the concept of the utility model, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and drawings, should be within the protection scope of the utility model.
