Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a maintenance auxiliary tool for cigarette machines, specifically a drum assembly and disassembly device for a ZJ17 type cigarette machine. Background Technology

[0002] Cigarette rolling machines are an indispensable piece of equipment in the cigarette production process. Their main function is to process materials such as tobacco, filters, and cigarette paper into finished cigarettes. The ZJ17 type cigarette rolling machine is currently the most widely used model in cigarette manufacturing enterprises. Its structure can be divided into the following three parts: the YJ17 type feeding and forming machine, the YJ17 type rolling and forming machine, and the YJ27 type filter tip attaching machine. Among them, the YJ27 type filter tip attaching machine achieves its function through drum drives with different structures and functions.

[0003] In practical operation, drums inevitably experience wear, pore blockage, and surface stains, requiring equipment maintenance. This involves removing the drum from the equipment for cleaning or replacement before reinstallation. Currently, the common method for disassembly and reassembly is manual. Manual disassembly and reassembly cannot guarantee the parallelism between the drum and the machine's mounting shaft, easily causing the drum to become misaligned and unable to be removed. It also causes wear on the mounting shaft. Furthermore, during drum disassembly and reassembly, issues such as assembly precision and oxidation of the mounting shaft (oxidation of the drum mounting shaft surface increases friction between the mounting hole and the mounting shaft, making the drum impossible to remove) contribute to difficulties and low efficiency, which are problems that enterprises urgently need to solve. Summary of the Invention

[0004] To address the problems of difficult and inefficient manual disassembly and assembly of drums in current cigarette making machines, which are often carried out by hand due to the weight of the drum, the installation method, and oxidation of the shaft surface, this invention provides a drum disassembly and assembly device for the ZJ17 cigarette making machine.

[0005] This utility model is achieved using the following technical solution:

[0006] A drum assembly / disassembly device for a ZJ17 cigarette machine includes a base plate trolley. A frame is supported on the base plate trolley via a hydraulic lifting mechanism. The frame includes a horizontally arranged base plate and a side plate vertically fixed to one end of the base plate. A pair of support inclined plates are fixed on the base plate. The two support inclined plates are facing each other and are arranged at an angle. A horizontal screw is provided between the two support inclined plates. The screw is connected to a threaded hole in the center of the side plate, forming a threaded pair. The screw axially penetrates the side plate. A handle that rotates synchronously with the screw is fixed to the end of the screw located on the outside of the frame. A connecting block is installed on the end of the screw located on the inside of the frame via a bearing. An electromagnetic device for connecting or releasing the drum is fixed on the connecting block.

[0007] In implementation, the system includes a base trolley, which comprises a frame and wheels mounted on the bottom of the frame. A handle is fixed to the end of the frame furthest from the electromagnetic device, extending upwards from the frame to form a gripping area. The wheels are casters equipped with self-locking devices that can switch between a locked position (preventing wheel rotation) and a released position (allowing free wheel rotation) to prevent the trolley from moving during drum assembly / disassembly. A frame is supported on the base trolley via a hydraulic lifting mechanism. The frame includes a horizontally arranged base plate and a side plate vertically fixed to one end of the base plate. A pair of support ramps are fixed to the base plate, facing each other and inclined relative to each other. The upper surfaces of the support ramps together form an upward-opening V-shaped support structure for temporarily placing the drum after disassembly or before installation. The bottom ends of each support ramp are fixedly connected to… On the base plate, the fixed ends of two supporting inclined plates are spaced a predetermined distance apart and arranged parallel to each other. A horizontal screw is provided between the two supporting inclined plates. The screw is connected to the threaded hole in the center of the side plate of the frame, and the screw axially penetrates the side plate. The end of the screw located on the outside of the frame is fixed with a handle that rotates synchronously with the screw. The end of the screw located on the inside of the frame is equipped with a connecting block through a bearing. An electromagnetic device for connecting or releasing the drum is fixed on the connecting block. The electromagnetic device includes a magnetic core and an excitation coil arranged around the magnetic core. The magnetic core has an adsorption end face for adsorbing the drum. The adsorption end face is magnetized by the magnetic field generated when the excitation coil is energized, and magnetically adsorbs the drum made of ferromagnetic material. When the excitation coil is de-energized, the magnetic core demagnetizes and releases the adsorption on the drum. Specifically, the adsorption end face is a flat surface to ensure full contact with the corresponding surface of the drum and obtain the maximum adsorption force. The magnetic core is made of a soft magnetic material with high permeability and low remanence, and the excitation coil is wound with insulated wire.

[0008] As an alternative, the side panel of the frame is removed, and the screw is directly mounted on the base plate carriage via a height-adjustable bracket, which is fixed between the handle and the frame.

[0009] In use, the operator first pushes the handle of the base trolley, and moves the device to the vicinity of the drum position of the ZJ17 cigarette machine using the universal wheels equipped with self-locking devices. After positioning, the self-locking device is stepped on to lock the wheels in an anti-rolling state, ensuring the stability of the base trolley during subsequent operations. The hydraulic lifting mechanism is then activated, and the frame height is adjusted to the horizontal position of the drum's central axis, aligning the frame side plate with the drum's mounting surface. The handle is turned to drive the screw towards the drum, which moves the connecting block and electromagnetic device forward until the flat adsorption end face of the electromagnetic device is completely in contact with the drum surface. The excitation coil is energized, and the soft magnetic core is magnetized to generate a strong adsorption force, attracting the ferromagnetic drum. The drum is then removed, and the handle is turned in the opposite direction to retract the screw, smoothly moving the drum out until it falls into the V-shaped support structure of the supporting inclined plate.

[0010] Compared with the prior art, this application has the following advantages:

[0011] This utility model provides a drum wheel disassembly and assembly device for a ZJ17 cigarette machine. The device uses an electromagnetic mechanism to fix the drum wheel in place, and a coaxial screw rotation ensures parallelism between the drum wheel mounting shaft and the mounting hole during disassembly, thus guaranteeing smooth drum wheel assembly and disassembly. The device replaces the manual disassembly method of supporting the drum wheel vertically while moving it horizontally with an electromagnetic mechanism that provides vertical support and simultaneously shifts the axial force of the screw rotation horizontally, reducing the difficulty and improving efficiency. Furthermore, if impurities such as tobacco dust or oxide layers, which increase frictional resistance, are present on the drum wheel mounting shaft or in the mounting hole during disassembly, the device increases the torque of the screw mechanism, ensuring smooth drum wheel assembly and disassembly.

The adsorption end face is magnetized by the magnetic field generated when the excitation coil is energized, and the drum made of ferromagnetic material is magnetically adsorbed. When the excitation coil is de-energized, the magnetic core demagnetizes and releases the adsorption of the drum.

The hydraulic lifting mechanism 9 is activated, and the height of the frame 2 is adjusted to the horizontal position of the drum's central axis, so that the side plate of the frame 2 is aligned with the drum mounting surface. The handle 8 is turned to drive the screw 3 to move towards the drum, which drives the connecting block 5 and the electromagnetic device 6 forward until the flat adsorption end face of the electromagnetic device 6 is completely in contact with the drum surface. The excitation coil is energized, and the soft magnetic material core is magnetized to generate a strong adsorption force, which attracts the ferromagnetic drum. The drum is removed, and the handle 8 is turned in the opposite direction to retract the screw 3, so that the drum is moved out smoothly until it falls into the V-shaped support structure of the supporting inclined plate 4.
