Description

Tensioning wheel cleaning device

Technical Field

The utility model relates to a tobacco production equipment technical field, concretely relates to take-up pulley cleaning device.

Background

In the tobacco production equipment field, the drive belt is by extensive application, and the drive belt is often used with the take-up pulley collocation in the use. The tensioning wheel presses on the transmission belt, plays the effect of tensioning the transmission belt, makes the transmission belt keep certain tensile force all the time.

FIG. 1 is a schematic illustration of a prior art belt tensioner in a high position. As shown in fig. 1, the tension pulley 10 presses on the belt 100, and the belt 100 moves from left to right, thereby rotating the tension pulley 10 counterclockwise. Although the use of the tensioning wheel 10 serves to maintain the belt under tension at all times, problems which are difficult to overcome in the actual tobacco production process still occur. The problems are that: when smoke or other fine powder falls between the belt 100 and the pulley 10, the smoke may adhere to the surface of the pulley 10 by the rolling action therebetween, which may cause the belt 100 to be rapidly elongated or to come off the pulley 10. In order to solve the problem, a cleaning device with a scraper knife is often adopted in the prior art to clean the attached smoke on the surface of the tension pulley in time.

However, the cleaning device with the attached blade is often adopted in the prior art, and the displacement factor of the tension wheel 10 is not fully considered in design, so that the cleaning device with the attached blade in the prior art is limited in use. When the new belt 100 is not stretched, the tensioner 10 need only be in the high position as shown in fig. 1 to tension the belt. However, when the belt 100 is running for a certain period of time, the belt 100 will naturally stretch, and the idler 10 needs to be in the low position as shown in fig. 2 to maintain the original tension of the belt. As the belt 100 is elongated, the tensioner 10 position is displaced a greater amount. Since the cleaning apparatus with the blade of the related art can perform only the cleaning task when the tension pulley is at a specific position, the cleaning task is often not sufficiently performed when the tension pulley 10, which is moved stepwise and can move a large distance, is aimed at.

Therefore, there is an urgent need to design a tensioner cleaning device that can accommodate the change in the position of the tensioner.

In view of the above-mentioned drawbacks, the authors of the present invention have finally obtained the present invention through long-term research and practice.

The eccentric shovel blade holder 3 is internally provided with a rotating shaft, and the axis of the rotating shaft does not coincide with the axis of the eccentric shovel blade holder 3 body.

When the rotation lock is in an unlocked state, the eccentric blade holder 3 and the blade 2 can rotate together along the rotation axis.

The scraper knife 2 can change the effective length and can rotate along an eccentric rotating shaft. The beneficial effects are that: the moving range of the scraper knife 2 is enlarged, and even if the tensioning wheel 10 has large displacement, the position of the scraper knife head of the scraper knife 2 can be well matched with the position of the tensioning wheel 10, so that the cleaning task can be fully completed.

The tensioning wheel cleaning device can well clean smoke on the surface of the tensioning wheel no matter the tensioning wheel is in a high position state or a low position state. Even if the tensioning wheel has large displacement, the tensioning wheel cleaning device can still be well applied.

Example two

The difference between the present embodiment and the first embodiment is:

Preferably, the outer cylindrical surface of the eccentric blade holder 3 is cut, so that a concave land 7 is created, which concave land 7 is a square concave land. The square concave table has the beneficial effects that: the installation of the scraper knife 2 is convenient.

The concave platform 7 is provided with a threaded hole 8 for installing the scraper knife 2. The shovel blade 2 can be installed in the concave platform 7 through the matching of the first threaded connector 1 and the threaded hole 8.

FIG. 6 is a schematic view of the position of the blade when the tensioner is in the high position in this embodiment; fig. 7 is a schematic view of the position of the blade when the tensioner is in the low position state in this embodiment. As shown in fig. 6 and 7, it can be seen from the two figures that the position of the protruding concave platform of the eccentric blade seat 3 of the blade 2 is different from the circumferential position of the eccentric blade seat 3. I.e. the eccentric blade holder 3 is rotated circumferentially and the effective length of the blade 2 is adjusted.

step S1, setting the position of the tension pulley 10;

and step S2, loosening the first threaded connecting piece 1 and the second threaded connecting piece 5, and adjusting the position of the scraper knife 2 relative to the concave platform 7 and the circumferential position of the eccentric seat 3 to ensure that the cleaning cutting edge of the scraper knife 2 is positioned at the tangential position of the outer circumferential surface of the tension wheel 10.

And step S3, screwing the first threaded connector 1 and the second threaded connector 5.

Step S4, the conveyor belt is started, and the tensioning wheel cleaning device cleans the tensioning wheel 10.

The beneficial effects are that: the first threaded connecting piece 1 can be conveniently inserted into the waist-shaped adjusting hole 12 to tightly press the scraper knife 2.

The length of the waist-shaped adjusting hole 12 is designed according to the displacement which needs to be adjusted.

Clean blade 11 adopts 45 chamfer blades, and the blade parallel and level and sharpness, its beneficial effect lies in: can effectively clean the surface smoke of take-up pulley 10.

The overall length of the blade 2 is also specifically set according to the actual eccentric blade holder 3 and tensioning wheel 10 position.

Preferably, the overall width of the blade 2 is 1mm wider than the overall width of the tension wheel 10, which has the following beneficial effects: the soot over the entire width of the outer circumferential surface of the tensioner 10 can be cleaned.

The scraper knife 2 is made of harder steel materials, and has the beneficial effects that: the steel shovel blade has high wear resistance.
