Description

Technical Field

[0001] This invention relates to the field of ironing technology for cigarette pack outer packaging film, specifically a dual-drive rapid clamping and ironing device for cigarette pack production. Background Technology

[0002] Tobacco manufacturers wrap cigarette packs in PVC transparent film. They then use heat shrinkage to reshape the exterior for a smoother, more aesthetically pleasing finish. However, current methods mostly involve simple machinery randomly ironing two parallel sides of the pack, or ironing the remaining two sides in stages. Most manufacturers can only iron all four sides, and some even still use manual methods with soldering irons.

[0003] The existing ironing methods have two main shortcomings:

[0004] First, the commonly used ironing method is a passive ironing method, which involves adding an ironing device downstream of the smoke bar outlet of the equipment and waiting for the smoke bar to be passively pushed into the ironing station. It is always in a passive waiting state. This commonly used method has strict requirements for the installation position of the ironing device. It must be an integer part of the width of the smoke bar to enter the ironing position. If the position is not accurate, the ironing device will collide and squeeze with the smoke bar. In severe cases, it may even damage the ironing device and the equipment. Therefore, it has flaws in terms of reliability and safety.

[0005] Secondly, existing ironing devices employ a step-by-step, progressive ironing process. During operation, the two parallel surfaces corresponding to the tobacco strip are ironed first, followed by the two parallel end faces. If ironing the remaining two vertical surfaces is required, an additional station must be added to rotate the device 90° to achieve full-range ironing. Even then, it remains a passive ironing method. Therefore, this method suffers from drawbacks such as cumbersome procedures, excessive station space requirements, and complex transmission mechanisms.

[0006] Third, the traditional method of manually ironing with a fixed soldering iron is a rather primitive method. It involves manually pressing each side of the cigarette pack against the heated soldering iron in turn. This method is inefficient, has a low safety factor, and is prone to burns if not handled properly. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a dual-drive rapid clamping and ironing device for cigarette bar production, which solves the aforementioned problems.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a dual-drive rapid clamping and ironing device for cigarette bar production, comprising a frame, a feeding conveying assembly disposed on one side of the frame for inputting cigarette bars, a placement mechanism for ironing the bottom and sides of the cigarette bars, a conveying mechanism for gripping the cigarette bars and ironing the top and sides, and an emptying conveyor belt for outputting the cigarette bars. The placement mechanism includes a placement seat rotatably disposed in the inner cavity of the frame and a drive cylinder rotatably disposed on the side of the frame. One end of the piston rod of the drive cylinder is rotatably connected to one side of the placement seat, and a soldering iron plate is fixedly connected to the top of the placement seat.

[0009] The handling mechanism includes a cam groove formed on the surface of the frame. A drive roller, driven by a drive assembly, is rotatably connected to the inner cavity of the cam groove to reciprocate along the cam groove. A connecting cylinder is inserted into the shaft end of the drive roller via a pin. A fixing frame is held by the piston rod end of the connecting cylinder. Side soldering irons, driven by double-rod cylinders, are provided on both sides of the fixing frame for heating the sides of the cigarette stick. An L-shaped soldering iron for heating the top and rear of the cigarette stick is fixed at the bottom of the fixing frame. The L-shaped soldering iron, side soldering irons, and receiving soldering iron plate combine to form a... The ironing assembly heats all six sides of the cigarette stick. When the cigarette stick enters the feeding conveyor assembly, the conveyor belt actively accelerates and transports it from the feeding conveyor assembly to the guide frame. Then, under the influence of gravity, it slides down to the placement seat. When an unsuitable cigarette stick is detected, the drive cylinder retracts, pulling the placement seat to the right and causing it to rotate 45° to the left. Under the influence of gravity, the cigarette stick falls and is removed. During this process, the upper and lower large surfaces are preheated. The receiving iron plate on the placement seat then irons the two lower vertical surfaces. Simultaneously, the fixed frame of the conveying mechanism... Figure 3 The vertical position shown indicates that the iron plate is rapidly lowered and pressed diagonally downwards to iron the two vertical surfaces of the upper part of the cigarette strip. At this time, the side irons on both sides of the conveying mechanism close under the action of the double-rod cylinder, completing the all-round ironing of the cigarette strip while clamping and transporting it to... Figure 3 Location, arrival Figure 3 The soldering irons on both sides of the position quick-transfer mechanism open and release smoke bars to the discharge conveyor belt, and the high-speed conveyor belt outputs the finished product.

[0010] As a further aspect of the present invention: the inner cavity of the frame is slidably connected to a longitudinal slide rail via a transverse slide rail, and one side of the connecting cylinder is slidably connected to the longitudinal slide rail. The longitudinal slide rail guides the connecting cylinder, enabling it to reciprocate more smoothly along the cam groove under the drive of the drive assembly.

[0011] As a further aspect of the present invention: the drive assembly includes a reciprocating gear rotatably mounted on the surface of the frame and driven by a motor to perform reciprocating motion. A drive rocker arm is fixedly connected to one side of the reciprocating gear. The inner cavity of the drive rocker arm is provided with a guide groove that is slidably connected to the drive roller. The reciprocating gear is driven to rotate left and right by the motor, which drives the drive rocker arm to swing left and right. When the drive roller moves along the cam groove, it moves up and down in the guide groove. This can precisely drive the drive roller to perform reciprocating motion, and iron the strip package delivered to the receiving soldering iron plate by the feeding conveyor assembly on all four sides during the clamping process. During the ironing process, the strip package is clamped and transported from the receiving soldering iron plate to the empty conveyor belt.

[0012] As a further aspect of the present invention: the feeding and conveying assembly includes a built-in conveyor belt and an electric heating plate disposed on the side of the conveyor belt, which preheats and irons the upper and lower surfaces of the strip package during the traction and conveying process to ensure the ironing quality of the overlapping surface.

[0013] As a further aspect of the present invention: a guide frame is fixedly connected to one side of the feeding and conveying assembly. When the placement seat is in the initial position, the guide frame and the surface of the placement seat form a straight line. The feeding and conveying assembly outputs the cigarette sticks to the guide frame via the conveyor belt, and then they slide down onto the placement seat under the action of gravity. When the cigarette sticks are detected to be unsuitable, the drive cylinder retracts and pulls the placement seat to the right, causing the placement seat to rotate 45° to the left. Under the action of gravity, the cigarette sticks fall down and are rejected.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention integrates the functions of ironing and handling cigarette strips, making the transmission more reliable, thereby improving the ironing speed and ironing efficiency per unit time, simplifying the ironing process, and better meeting the ironing needs of automated high-speed cigarette packing machines.

[0016] 2. In this invention, when the device detects defective products, the soldering iron is automatically rotated 45° under the action of the driving device to drop it and then reject it. Attached Figure Description
