Description

A belt conveyor with a three-stage cleaning device

technical field

The utility model relates to the technical field of tobacco shred production and conveying equipment, in particular to a belt conveyor with a three-stage cleaning device.

Background technique

A large number of belt conveyors are used in the silk production line for material transportation. During use, due to the special properties of tobacco materials, the surface of the conveyor belt is prone to fouling, and the rollers are squeezed during operation to cause fouling, which makes the equipment wear and deform. , eventually lead to the deviation of the conveying belt, which is easy to cause the belt to wear and form sundries mixed into the material to cause quality accidents; in addition, during the cleaning process of the existing cleaning device, the material is affected by the cleaning device and leaks out of the equipment, resulting in production waste.

Contents of the invention

In view of the above-mentioned shortcomings of the prior art, the utility model provides a belt conveyor with a three-stage cleaning device, which can improve the performance of the belt conveyor body, and at the same time ensure that the material directly enters the next equipment to the production line during the cleaning process. Reduce material waste.

A belt conveyor with a three-stage cleaning device, including a driving roller installed on a discharge wallboard, a driven roller, a conveyor belt wound on the driving roller and a driven roller, and the discharge wallboard is installed on the On the outrigger, the discharge wallboard is divided into the discharge section wallboard, the middle section wallboard and the tail wallboard from front to back, and it is characterized in that: it is located under the conveyor belt at the discharge section wallboard from front to back. There are first-stage scraper, second-stage rotary roller brush and third-stage scraper, the ends of the first-stage scraper and third-stage scraper are in contact with the back of the conveyor belt above, and the second-stage rotary roller The brushes rotate in the opposite direction of the conveyor belt and the ends of the second stage rotating roller brushes contact the back of the conveyor belt above.

As mentioned above, the belt conveyor with three-stage cleaning device has the same structure of the first-stage scraper and the third-stage scraper, including a scraper, a chute, and a scraper seat fixed on the discharge wall. The plate base is provided with at least two vertical chutes, and the locking piece passes through the fixing hole on the scraper plate and is locked on the chute, so that the scraper is fixed on the scraper seat, and the end of the scraper is connected to the upper conveyor belt back contact.

As mentioned above, the belt conveyor with the three-stage cleaning device, the second-stage rotary roller brush includes a rotating shaft parallel to the roller shaft of the driving roller and a plurality of bristles extending outward along the circumferential direction of the rotating shaft. The ends contact the back of the conveyor belt above, and the bristles turn in the opposite direction of the conveyor belt.

The new model is reasonable in design, simple in structure and easy to implement. Through the combination of three-level cleaning working methods, it can effectively remove the adhesion and fouling on the belt surface, and can solve the problem of tobacco scaling on the belt surface of the conveyor belt; in addition, the first and third-level scrapers The second-stage roller brush is sealed to prevent material dust from flying and causing leakage when the roller brush is cleaning. The entire cleaning process is carried out in the discharge section, so that the scale is removed by the brush and directly falls into the next equipment and enters the production line to avoid material leakage. Drain waste.

Detailed ways

The technical solution in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model.

Fig. 1 shows the structural representation of the belt conveyor of the utility model with a three-stage cleaning device. The belt conveyor with a three-stage cleaning device includes a driving roller 1 and a driven roller installed on the discharge wallboard 6. Wind the conveying belt 2 arranged on the driving roller 1 and the driven roller 6, and install the discharge wallboard on the supporting leg 7. The discharge wallboard is divided into a discharge section wallboard 3, a middle section wallboard 4 and a tail wallboard 5 from front to back, the driving roller 1 is installed on the discharge section wallboard 3, and the driven roller 6 is installed on the tail wall There are 5 places on the board.

Below the conveying belt 2 at the wallboard 3 of the discharge section, there are first-stage scrapers 10 , second-stage rotary roller brushes 9 and third-stage scrapers 8 in sequence from front to back. Please refer to Fig. 2, the structure of the first-stage scraper 10 and the third-stage scraper 8 are the same, including a scraper 12, a scraper seat 11 and a chute 13, and the scraper seat 11 is provided with at least two slides in the vertical direction. Slot 13, the locking member (such as a screw) passes through the fixing hole on the scraper 12 and locks to the chute 13, thereby fixing the scraper 12 on the scraper seat 11, and the end of the scraper 12 and the driving roller 1 convey the belt 2 in order to achieve the purpose of scraping cleaning. When the scraper 12 is worn, the scraper 12 can be raised along the chute 13 according to the actual situation to prevent failure. The scraper seat 11 is fixed on the discharge wallboard.

Please refer to Fig. 3, described second stage rotary roller brush 9 comprises the rotating shaft 91 that is arranged in parallel with the roller shaft of driving roller 1 and a plurality of brush hairs 92 that extend outward along rotating shaft 91 circumferential direction, the end of brush hair 92 and driving roller The back side of the conveying belt 2 at one place is in contact, and the direction of rotation of the bristles 92 is opposite to that of the conveying belt 2 .

When the conveyor is working, the driving roller 1 drives the conveyor belt 2 to run; a three-stage cleaning device (namely, the first-stage scraper 10, the second-stage rotary roller brush 9 and the third-stage cleaning device) is fixedly installed on the wall panel 3 of the discharge section. Scraper 8); when the conveyor belt 2 is in operation, first pass through the gap between the drive roller 1 and the first-stage scraper 10, and through the action of the first-stage scraper 10, the larger and loose dirt on the belt surface is initially removed; When the conveyor belt runs to the top of the second-stage rotary roller brush 9, because the belt running direction is opposite to the direction of the roller brush, through the action of the bristles 92 of the second-stage rotary roller brush 9, the scale with strong adhesion on the belt surface will be removed. Brush off or be brushed loose; when the belt runs to the third-level scraper 8, under the action of the scraper, the accumulated scale is brushed off. The whole cleaning process is carried out in the discharge section, so that the accumulated scale is directly dropped into the next equipment and enters the production line after being brushed to avoid material leakage and waste.

The utility model has the following beneficial effects:

1. Through the combination of three-level cleaning work methods, the adhesion and fouling on the belt surface can be effectively removed;

2. The first and third-level scrapers seal the second-level roller brush to prevent material dust from flying and causing leakage when the roller brush is cleaning;

3. After the action of the cleaning device, the accumulated scale is directly used in the production line to avoid waste.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any skilled person in the technical field can easily think of changes within the technical scope disclosed in the utility model Or replacement, all should be covered within the scope of protection of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
