Description

Technical Field

[0001] The present application relates to the field of cigarette making equipment, and in particular to a filter rod conveying and stabilizing device for an accelerating wheel position of a high-speed forming machine, a filter rod forming machine, and cigarette making equipment. Background Art

[0002] In cigarette making equipment, the manufacturing of filter rods for cigarettes is mainly achieved through filter rod forming machines. In the current filter rod forming machine design, the outlet end of the filter rod forming chamber is specially configured with two acceleration wheels. These two acceleration wheels effectively complete the transition and transportation task of the formed filter rods through their negative pressure adsorption function. Figure 1 As shown, in existing filter rod forming machines, the negative pressure air required by the acceleration wheel is supplied through a directly connected negative pressure air duct. However, this design has obvious limitations: the amount of negative pressure air it supplies cannot be adjusted. Furthermore, as the equipment operates, the negative pressure air volume provided by the negative pressure air duct may become insufficient due to wear or other factors. This insufficient negative pressure air volume can easily cause the formed filter rods to jump or slip during conveying, potentially causing the equipment to shut down and reducing its overall operating efficiency. Utility Model Content

Two acceleration wheels 10 are arranged at the outlet end of the filter rod forming cavity in the forming machine. The acceleration wheels have negative pressure adsorption holes for adsorbing the filter rods formed in the transition conveying forming cavity. The device includes: a joint 30 and a negative pressure compensation pipeline.

[0026] One end of the connector is connected to the negative pressure air duct 20 configured for the molding machine, and the other end of the connector has two negative pressure interfaces 31, and the two negative pressure interfaces are respectively connected to the two acceleration wheels through the air circuit pipe 32; a negative pressure compensation interface 32 is provided at the side wall end of the connector, and a vacuum generator and a throttle valve 41 are provided in the negative pressure compensation pipeline 40, and the negative pressure compensation pipeline near the end of the vacuum generator is connected to the air supply source air circuit; the negative pressure compensation pipeline near the end of the throttle valve is connected to the negative pressure compensation interface; the vacuum generator is used to convert the gas provided by the air source air circuit into negative pressure wind, and the throttle valve is used to adjust the amount of negative pressure wind output by the negative pressure compensation pipeline.

[0027] Furthermore, the connector is externally disposed on a filter rod forming cavity component in a forming machine, and the connector is provided on an outer wall of the filter rod forming cavity component; or, the connector is provided on an inner wall of a casing in a forming machine.

[0028] The proposed device for stabilizing filter rod conveying at the acceleration wheel position of a high-speed forming machine, introduced in this application, utilizes a negative pressure compensation pipeline mechanism to implement a precise negative pressure compensation strategy on the acceleration wheel. This ensures that the formed filter rods are subjected to stable negative pressure adsorption during conveyance, significantly reducing the risk of problems such as rod jitter and deviation during transport. Furthermore, this device innovatively utilizes an external connector design, which greatly optimizes the subsequent maintenance and servicing of the stabilizing device, improving the convenience and efficiency of overall operation.
