Device for manufacturing hollow filter stick

Abstract

The invention discloses a device for manufacturing a hollow filter stick with a special shape. A certain distance is spaced between a forming machine and an opener; a steam hardening device is mounted within the section of the distance and comprises a group of high pressure air nozzles, a forming tongue, a cloth band mechanism used for clamping a tow band to move forward, a cigarette gun passage and a steam generator, wherein the cloth band mechanism is connected with a host driving device; the high pressure air nozzles are connected with the opener and used for receiving the tow band conveyed by the opener while output ends of the high pressure air nozzles are communicated with the forming tongue; the tow band is conveyed into the forming tongue; and a strip-shaped hollow mould is fixed on the front end of the forming tongue. The invention has the advantage that a better hardening promoting effect can be obtained because the steam hardening device and a plasticizer heating device (the steam generator) are added. Moreover, in the product, the curing time of the filter stick is largely shortened by using modified glyceride.

Description

technical field [0001] The invention relates to a filter rod, in particular to a production device for manufacturing the filter rod. Background technique [0002] At present, it is generally used to add filter rods to cigarettes to reduce the harm of smoking to the human body. However, ordinary filter rods are only composed of tow and formed paper. The process of smoke passing through the filter rods is relatively common, and the filtering effect on harmful components such as smoke tar is limited. It can no longer meet the requirements of cigarette factories for cigarette products and consumers' increasing concern about smoking and health. Therefore, changing the original filter rod structure and further reducing harmful components in smoke has become a top priority. The hollow special-shaped filter rod production device was developed by MonTrade Srl in Italy, but its structure is relatively complicated and the price is very high, which is simply unacceptable to general manu...

[0002] At present, it is generally used to add filter rods to cigarettes to reduce the harm of smoking to the human body. However, ordinary filter rods are only composed of tow and formed paper. The process of smoke passing through the filter rods is relatively common, and the filtering effect on harmful components such as smoke tar is limited. It can no longer meet the requirements of cigarette factories for cigarette products and the increasing concern of consumers on smoking and health. Therefore, it has become an urgent task to change the original filter rod structure and further reduce the harmful components in the smoke.

The hollow special-shaped filter rod production device was developed by MonTrade Srl in Italy, but its structure is relatively complicated and the price is very high, which is unacceptable to general manufacturers.
