Problems solved by technology

When working, the filter rod forming machine pulls the tow and pulls it out of the tow bag. Since the tow must be arranged in a certain way in the tow bag, the distance from each point to the tow outlet is different. The direction of movement in the process is also changing at any time, resulting in unstable tow supply speed, which will cause fluctuations in the supply of tow; in addition, when packing, the top and bottom are under greater pressure and the compression is large, and the middle part It is relatively loose and has a small amount of compression, which will also lead to fluctuations in the suction resistance of the filter rods produced by the molding machine due to different traction forces during use

Embodiment 1

[0027] Such as figure 1 As shown, a tow supply device includes a tow buffer box. The left side of the tow buffer box is a guide chamber 1, and the right side is a storage chamber 2. The tow is first stored in the storage chamber 2, and then passes through the guide chamber. Provided to the tow filter rod forming machine 7, there are two pairs of guide plates 3 with adjustable gaps in the horizontal direction and opposite gaps in the vertical direction in the guide cavity. When the tow passes through the gap between each pair of guide plates 3, it is drawn The guide plate 3 adjusts the direction of transmission, and enters the filter rod forming machine at a fixed orientation, avoiding the fluctuation of the suction resistance value caused by the tow swing caused by directly extracting the tow from the tow bag, and at the same time, because the filter rod forming machine If the pulling force is constant and the amount of tow stored in the storage area is constant, the stability...

Embodiment 2

[0030] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that three material level monitors 4 are vertically arranged in the storage cavity, and the material level monitor 4 is a photoelectric sensor, and the transmitter and receiver of the photoelectric sensor Oppositely installed on the side wall of the storage cavity, a plurality of the photoelectric sensors are respectively electrically connected to a plurality of flow control input ends of each of the proportional valves, when a tow blocks the photoelectric sensor, the receiver cannot receive the signal , send a signal to the flow adjustment input end of the corresponding proportional valve to adjust the transmission speed of the main air conveyor. The lower end corresponds to the first gear slow flow adjustment input end; at the same time, each photoelectric sensor from bottom to top corresponds to different alarm signals, the lowest end is used as an early warning alarm, and the high...

Abstract

The invention provides a tow feeding device. The tow feeding device comprises a tow buffering box which is provided with a guiding cavity and a storing cavity, the lower portion of the guiding cavity is communicated with the lower portion of the storing cavity, at least one guiding mechanism is arranged in the guiding cavity in the vertical direction, and each guiding mechanism comprises a pair of guiding parts with the gap adjustable in the horizontal direction; a main air conveyor communicated with the storing cavity is arranged on the side wall of the upper portion of the tow buffering box. The tow feeding device has the advantages of being scientific in design and stable in tow feeding, and reducing fluctuation of suction resistance of a filter stick.

Description

technical field [0001] The invention relates to a filter rod forming equipment, in particular to a tow supply device. Background technique [0002] The existing tow package is generally a cuboid with a volume of 1000mm×800mm×1000mm (length×width×height), and enters the filter rod forming machine through a circular guide mechanism with a guide rod at the tow outlet. When working, the filter rod forming machine pulls the tow and pulls it out of the tow bag. Since the tow must be arranged in a certain way in the tow bag, the distance from each point to the tow outlet is different. The direction of movement in the process is also changing at any time, resulting in unstable tow supply speed, which will cause fluctuations in the supply of tow; in addition, when packing, the top and bottom are under greater pressure and the compression is large, and the middle part It is loose and has a small amount of compression, which will also lead to fluctuations in the suction resistance of ...
