TECHNICAL FIELD
[0001] The utility model relates to tobacco packaging equipment technical field, concretely relates to a magnetic clutch protection device for cigarette rod lifting mechanism. BACKGROUND
[0002] As a key link in the tobacco manufacturing process, the mechanical automation degree of the cigarette rod packaging process is directly related to the production efficiency and product quality. The process mainly includes small box packaging, cigarette rod packaging and heat shrink film packaging. In the packaging process, the packaging equipment first packs the completed cigarette rod into a small box according to a predetermined number, then packs the small box according to a certain number, and finally performs heat shrink packaging through a heat shrink film. In this series of processes, the cigarette rod needs to be lifted from the bottom position to the high position by the lifting machine and enter the heat sealing channel.
[0003] The lifting machine used in the prior art mainly includes an electric push rod type lifting mechanism and a lifting plate. The cigarette rod is placed on the lifting plate, the ball screw of the electric push rod is driven by the servo motor to drive the lifting plate to vertically displace, so as to lift the cigarette rod from the end of the conveying belt (low position platform) to the high position heat sealing channel entrance.
[0004] However, on the high-speed running cigarette rod packaging production line, the cigarette rod may be blocked. However, the traditional lifting machine is almost not equipped with any protection device, so that when the cigarette rod is blocked, the cigarette rod packaging production line will continue to run at high speed until the lifting machine is seriously overloaded and stopped, and then the production line will be temporarily stopped according to the signal. This situation will cause a large amount of cigarette rod to be extruded, resulting in material waste. At the same time, the production line is temporarily stopped only when the lifting mechanism is seriously overloaded, which will cause great damage to the equipment and increase the maintenance cost. At the same time, the production line maintenance caused by overload shutdown will greatly reduce the production efficiency.
[0005] To solve the above problems, the utility model is proposed. UTILITY MODEL CONTENT
[0006] To solve the problems of the prior art, the purpose of the utility model is to provide a magnetic clutch protection device for a cigarette rod lifting mechanism. The device can send an alarm signal in time when the cigarette rod is blocked, and the packaging production line will immediately stop running after receiving the signal, thereby effectively avoiding the extrusion deformation of the cigarette rod, the overload of the equipment and the high maintenance cost. At the same time, the production line downtime caused by equipment failure is significantly reduced, and the overall production efficiency is improved.
[0007] The technical scheme adopted by the utility model is:
[0008] The application provides a magnetic clutch protection device for a cigarette rod lifting mechanism, which comprises a lifting plate 1, a supporting shaft 2, a base 3, a magnet 4, an adsorbing iron sheet 5 and a detector 6.
[0009] Preferably, the number of the supporting shafts 2 is two, and the two supporting shafts 2 are symmetrically arranged; two through holes 31 are formed in positions where the two supporting shafts 2 penetrate the base 3, and the diameters of the through holes 31 are slightly larger than the outer diameters of the two supporting shafts 2, so that the supporting shafts 2 can slide in the through holes 31.
[0010] Preferably, the detector 6 is an inductive proximity switch, and the detector 6 is connected with a control mainboard of a cigarette rod packaging production line; when the detector 6 detects that the lifting plate 1 approaches, the detector 6 can timely judge that the cigarette rod is blocked and control the production line to stop running.
[0011] Preferably, the detector 6 is connected with the side wall of the base 3 and located below the lifting plate 1.
[0012] Preferably, the top ends of the two supporting shafts 2 are symmetrically connected with the middle part of the lifting plate 1, and the bottom ends of the two supporting shafts 2 are symmetrically connected with the middle part of the adsorbing iron sheet 5.
[0013] During the operation of the packaging production line, when the cigarette rod is not blocked, the magnet 4 is in a magnetic attraction connection state with the adsorbing iron sheet 5, and the lifting plate 1 is located away from the detector 6; at this time, the control mainboard recognizes that the cigarette rod is not blocked, and the production line normally operates.
[0014] When the cigarette rod is blocked, the lifting plate 1 is subjected to a force opposite to the movement direction during the process of lifting the cigarette rod, and the force is greater than the gravity of the cigarette rod during the normal lifting process; finally, the magnetic attraction connection between the magnet 4 and the adsorbing iron sheet 5 is disconnected; at this time, the supporting shaft 2 slides downward along the through hole 31, the lifting plate 1 approaches the detector 6, the detector 6 senses the approach of the lifting plate 1 and transmits a signal to the control mainboard; the control mainboard immediately sends a signal to stop the operation of the production line, so as to avoid problems such as extrusion of the cigarette rod or overload of the lifting machine.
[0015] The application has the following beneficial effects:
[0016] 1. When the cigarette rod is blocked, the magnetic clutch protection device can quickly sense the blocking of the cigarette rod by the disconnection of the magnet and the adsorbed iron sheet, and the timely monitoring of the detector. After the main board receives the signal, the operation of the production line will be stopped immediately, thereby avoiding the continuous operation of the equipment under overload conditions and reducing the damage to the equipment caused by overload shutdown.
[0017] 2. By preventing the cigarette rod from being squeezed and deformed or the lifting mechanism from being overloaded, the device effectively protects the cigarette rod and equipment in the production line, reduces material waste, and avoids large-scale production line shutdown caused by equipment damage or failure, thereby reducing maintenance costs and downtime.
[0018] 3. By timely detecting and responding to the cigarette rod blocking problem, the production line can quickly stop when the blocking occurs, thereby preventing the extension of the production line downtime, which significantly improves the production efficiency and reduces the production stagnation caused by equipment failure or overload.
[0019] 4. The protection device is simple in design and adopts the combination of a magnetic clutch and an inductive proximity switch, which can quickly respond when an abnormality occurs, ensuring the safety and stability of the production process. Through the design of the sliding support shaft, the smooth movement of the lifting plate in normal operation is ensured, further enhancing the reliability of the device.

[0028] The present invention will be further described in detail below with reference to embodiments, but this is not intended to limit the present invention. Any modifications or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the field or in accordance with the product manual.
[0029] Example 1
[0030] As attached Figures 1-4 As shown, a magnetic clutch protection device for a cigarette bar lifting mechanism includes a lifting plate 1, a support shaft 2, a base 3, a magnet 4, an adsorption iron sheet 5, and a detector 6. The support shaft 2 passes through the base 3, and the two are clearance-fitted. The top end of the support shaft 2 is connected to the lifting plate 1, and the bottom end of the support shaft 2 is connected to the adsorption iron sheet 5. The magnet 4 is fixedly connected to the bottom end of the base 3 and is magnetically connected to the adsorption iron sheet 5. The detector 6 is connected to the side wall of the base 3 for monitoring the position of the lifting plate 1. Preferably, there are two support shafts 2, which are symmetrically arranged. Two through holes 31 are correspondingly opened at the positions where the two support shafts 2 pass through the base 3. The diameter of the through holes 31 is slightly larger than the outer diameter of the two support shafts 2, thereby allowing the support shafts 2 to slide in the through holes 31. The support shafts 2 are not cylindrical.
[0031] In a preferred embodiment, the lifting plate 1 comprises an upper rectangular plate and a lower rectangular block, with the outer edge of the upper rectangular plate chamfered. Chamfering the outer edge of the upper rectangular plate facilitates the feeding of the cigarette strip onto the lifting plate 1, while the design of the upper rectangular plate and the lower rectangular block allows for easy connection between the lifting plate 1 and the support shaft 2.
[0032] In a preferred embodiment, the base 3 has a groove at its bottom, and one end of the magnet 4 is fixed within the groove. The groove is located in the middle of the bottom of the base 3, allowing the magnet 4 to adhere to the center of the adsorption sheet 5. This design ensures a more stable position for the magnet, preventing displacement due to vibration or other external forces. The groove also helps protect the magnet from external impact damage. Positioning the groove in the middle of the base's bottom ensures that the magnet 4 can precisely adhere to the center of the adsorption sheet 5, thereby ensuring the uniformity and stability of the magnetic connection.
[0033] As a preferred embodiment of the present application, the base 3 is in the shape of a "convex" as a whole, and the two through holes 31 are arranged on the convex part of the base 3. The detector 6 is arranged on the concave part of the base 3 and connected to the side wall of the convex part of the base 3 by the "L" shaped bracket 61. This design can better integrate the components and effectively enhance the stability and reliability of the overall structure. The convex part is used to place the through holes to ensure that the support shaft can slide smoothly. The detector 6 is arranged on the concave part of the base 3 and connected to the side wall of the convex part of the base 3 by the "L" shaped bracket 61. This arrangement not only helps to maintain the appropriate distance between the detector and the lifting plate, but also prevents the detector from failing due to external interference, improving the adaptability and stability of the device.
[0034] The detector 6 is an inductive proximity switch. The detector 6 is connected to the control mainboard of the cigarette rod packaging production line. When the detector 6 detects that the lifting plate 1 is close, it can timely judge that the cigarette rod is blocked and control the production line to stop running.
[0035] The detector 6 is connected to the side wall of the base 3 and located below the lifting plate 1.
[0036] The two ends of the two support shafts 2 are symmetrically connected to the middle part of the lifting plate 1 and the middle part of the adsorbing iron sheet 5, respectively.
[0037] The lifting plate in the traditional lifting machine is replaced by the protection device. Specifically, the side wall of the base 3 is fixedly connected to the electric push rod type lifting mechanism of the existing lifting machine. During the operation of the packaging production line, as shown in Figure 3 , when no cigarette rod blockage occurs, the magnet 4 and the adsorbing iron sheet 5 are in a magnetic attraction connection state, and the lifting plate 1 is located away from the detector 6. At this time, the control mainboard recognizes that no blockage occurs, and the production line runs normally.
[0038] As shown in Figure 1 , when the cigarette rod is blocked, the lifting plate 1 will be subjected to a force opposite to the direction of motion during the process of lifting the cigarette rod. This force is greater than the weight of the cigarette rod during normal lifting. Finally, the magnetic attraction connection between the magnet 4 and the adsorbing iron sheet 5 is disconnected. At this time, the support shaft 2 will slide downward along the through hole 31, and the lifting plate 1 will approach the detector 6. The detector 6 senses the approach of the lifting plate 1 and transmits a signal to the control mainboard. The control mainboard immediately sends a signal to stop the production line from running, avoiding problems such as cigarette rod being squeezed or the lifting machine being overloaded.
[0039] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application. The dimensions described in the drawings and the embodiments are not related to specific objects and are not used to limit the protection scope of the present application. The dimensions of the objects can be selected and changed according to actual needs.
