Abstract
The invention belongs to the technical field of machinery, and relates to a compression roller capable of rotating only in one direction. The bobbin paper supply system of the cigarette making machine set is provided with the compression roller rotating in one direction for preventing the paper tape from reversely returning when the paper tape is fed, when the compression roller works, the paper tape can feed in the forward direction and enter the paper supply channel of the cigarette making machine set, and when the front tension is loose, the paper tape can be prevented from reversely returning. The rollers can only rotate in one direction under the action of the one-way backstop, the rollers rotate normally when supplying paper, the paper tape tends to return when the front tension is relaxed, but the compression rollers cannot rotate in the opposite direction to prevent the paper tape from reversely returning so as to ensure stable and smooth paper supply.
Description
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to a compression roller only capable of rotating in a single direction.
Background
Most of the cigarette making and connecting units of the existing tobacco machinery use a full-automatic bobbin paper supply system, and the cigarette paper and the tipping paper can be supplied in a full-automatic manner. In the process, the phenomenon that the paper tape tension in front is loosened when the paper tape enters a paper feeding channel of the cigarette making and tipping machine set occasionally, the paper tape tends to return, if the paper tape is easy to shake and even break, a compression roller which can only rotate in one direction is configured for preventing the paper tape from returning, and stable and smooth paper feeding can be ensured.
Disclosure of Invention
The invention relates to a compression roller capable of rotating only in one direction, which comprises a mandrel, a bearing, a roller, a one-way backstop and a check ring. The rollers can only rotate in one direction under the action of the one-way backstop, the rollers rotate normally when supplying paper, the paper tape tends to return when the front tension is relaxed, but the compression rollers cannot rotate in the opposite direction to prevent the paper tape from reversely returning so as to ensure stable and smooth paper supply.
The invention has the following beneficial effects:
the invention has the beneficial effects that:
due to the action of the one-way backstop, the paper tape can be effectively prevented from returning, stable and smooth paper tape supply is ensured, and the paper tape feeding device is simple in structure and convenient to install.
Drawings
FIG. 1 is a general schematic view of a roll capable of rotating only in one direction according to the present invention;
in the figure: 01 mandrel, 02 bearing, 03 roller, 04 one-way backstop and 05 retaining ring.
Detailed Description
The present invention will be further described with reference to the following examples, but the present invention is not limited to the following examples.
Referring to fig. 1, a press roll capable of rotating only in one direction includes a mandrel (01), a bearing (02), a roller (03), a one-way check device (04), and a retainer ring (05).
And a bearing (02), a roller (03), a one-way backstop (04) and a check ring (05) are arranged on the mandrel (01). The inner rings of the two bearings (02) are matched with the mandrel (01), and the outer rings are matched with the roller (03). The inner ring of the one-way backstop (04) is matched with the mandrel (01), and the outer ring is matched with the roller (03). The retainer ring (05) is arranged at one end of the mandrel (01) and plays a role in axially positioning the roller (03) under the combined action of a shaft shoulder of the mandrel (01) and a step of the roller (03). The one-way backstop (04) is exemplified here by F4-HF 1216.
The working principle is as follows: firstly, the mandrel (01), the bearing (02), the roller (03), the one-way backstop (04) and the retainer ring (05) are assembled according to the drawing, the installation direction of the one-way backstop (04) is determined according to the paper feeding direction during assembly, and the rotatable direction of the roller is determined to be consistent with the paper feeding direction. The mandrel (01) is then mounted as required at the desired location of the apparatus. The initial paper tape bypasses the compression roller and is pressed on the corresponding guide roller, when the equipment runs to feed paper, the paper tape runs along the paper feeding direction and the compression roller can rotate along with the paper tape, and when the tension of the front square paper tape is loose and the paper tape has a retraction trend, the compression roller can not rotate reversely, so that the paper tape is prevented from retracting.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention, the technical solutions and their concepts equivalent to or modified by the present invention within the technical scope of the present invention.
