Description

Technical Field

[0001] The utility model relates to the field where raw materials or materials need to be conveyed by a belt, and more specifically to a cleaning device for cleaning the inner side of the conveyor belt of a belt conveyor with glass mixture. Background Art

[0002] In the field of glass production, the mixture required for glass production (including broken glass, so it is also called glass mixture) must be conveyed to the kiln by a belt conveyor. During this conveying process, often part of the mixture enters the inner side of the conveyor belt and enters the driven roller along with the conveyor belt. The mixture circulates and rolls between the driven roller and the belt. If these mixtures cannot be effectively cleaned, the mixtures will adhere to the surface of the driven roller, and finally may lead to: damage to the inner side of the conveyor belt, deviation of the conveyor belt from the set position due to caking on the surface of the driven roller, large leakage of the mixture, and direct reduction of the accuracy of the total amount of the mixture.

[0003] In the prior art, "V"-shaped rubber scrapers are usually arranged on the inner side of the conveyor belt. If the mixture falls into the inner side of the conveyor belt, the waste is discharged to both sides through the taper angle of the "V"-shaped rubber scraper.

[0004] However, due to the influence of the tensile forces on both sides of the conveyor belt, the actual working state of the conveyor belt is a curved surface, that is: convex in the middle and concave on both sides. The working surface of the "V"-shaped rubber scraper is a plane, so the scraper cannot be effectively attached to the conveyor belt. When the material passes through the position where the fit is not tight, the situation that the material cannot be cleaned thoroughly will occur.

[0005] The "V"-shaped rubber scraper is pressed onto the conveyor belt by its own weight, about 2 Kg. During the operation of the conveyor belt, there will be up and down fluctuations. The "V"-shaped rubber scraper will jump up and down with the conveyor belt. During the gap when the "V"-shaped rubber scraper jumps up and down, there will be a section of the conveyor belt that is not cleaned.

[0006] There is no stable fixed point at the front end of the taper angle of the "V"-shaped rubber scraper. The front end of the taper angle of the "V"-shaped rubber scraper is hung on the horizontal fixing rod by a hook. During the operation of the conveyor belt, the front end of the "V"-shaped rubber scraper will move left and right. When the front end of the "V"-shaped rubber scraper moves to one place, the "V"-shaped rubber scraper will give a reverse force to the conveyor belt, resulting in the situation of conveyor belt deviation. Content of the Utility Model

[0007] The purpose of the utility model is to provide a cleaning device for cleaning the inner side of the conveyor belt of a belt conveyor with glass mixture. The cleaning device uses two groups of roller brushes at an angle to perform the cleaning work, so as to achieve the purpose of automatically and effectively cleaning the mixture on the inner side of the conveyor belt.

[0008] According to one aspect of the present utility model, a cleaning device is provided. The cleaning device includes: a pulley unit, one end of which is connected to the main roller of a belt conveyor for obtaining power from the main roller; a power transmission unit, which is connected to the other end of the pulley unit and is used for transmitting the power from the pulley unit; a cleaning unit, which is connected to the power transmission unit and is used for cleaning the glass mixture by means of the power from the power transmission unit. Wherein, at the contact position between the cleaning unit and the conveyor belt, the moving direction of the cleaning unit is opposite to the moving direction of the conveyor belt of the belt conveyor to clean the glass mixture accumulated on the inner side of the conveyor belt.

[0009] According to this first aspect, the present utility model provides a novel device for cleaning the mixture on the inner side of the conveyor belt of a glass mixture belt conveyor, which can automatically clean the glass mixture entering the inner side of the conveyor belt.

[0010] According to an embodiment, the cleaning unit includes two brush rollers, which are attached to corresponding transmission shafts, and the rotation directions of the two brush rollers are the same. Through this embodiment, the glass mixture can be efficiently removed.

[0011] According to another embodiment, the two brush rollers partially overlap at one end close to each other in the transverse direction perpendicular to the running direction of the conveyor belt, and both extend beyond the conveyor belt at the end far from each other. According to this embodiment, the waste on the inner side of the conveyor belt can be completely removed. If a single brush roller is installed at an angle, such as a 45-degree angle, a force perpendicular to the moving direction of the conveyor belt will be given to the conveyor belt, causing the conveyor belt to deviate. To solve this problem, by adding a brush roller at a 45-degree angle in the opposite direction, the two brush rollers balance each other.

[0012] According to another embodiment, the power transmission unit includes two sets of bevel gears for power transmission, wherein the first set of bevel gears is used for transmitting power between the pulley unit and the cleaning unit, and the second set of bevel gears is used for transmitting power in the cleaning unit. By arranging components such as bevel gears, the two brush rollers are made to rotate in a direction opposite to the moving direction of the conveyor belt.

[0013] In another embodiment, the first set of bevel gears includes two bevel gears, one of which is connected to one end of the pulley unit, and the other is connected to one end of a transmission shaft of the cleaning unit. These two bevel gears mesh with each other to transmit power. The second set of bevel gears includes three bevel gears, one of which is connected to the other end of the said transmission shaft of the cleaning unit. This bevel gear meshes with another bevel gear serving as a common bevel gear to transmit power, and the common bevel gear meshes with a bevel gear on one end of another transmission shaft adjacent to the said transmission shaft of the cleaning unit, so as to transmit the power transmitted on the said transmission shaft to the said other transmission shaft. According to this arrangement, it is possible to make the two brush drums operate in cooperation through bevel gears, so that the rotational speeds and directions of the two brush drums are the same.

[0014] Preferably, the parameters of each bevel gear are the same, thus saving power.

[0015] In one embodiment, relative to the axis of the common bevel gear, the inclination angles of the two brush drums are the same but the inclination directions are opposite. By rotating the two brush drums in the direction of the conveyor belt, the waste falling inside the conveyor belt is swept out to both sides of the conveyor belt, thereby achieving the effect of automatically cleaning the conveyor belt.

[0016] In one embodiment, the inclination angles of the two brush drums are in the range of 30 degrees to 45 degrees, and preferably 45 degrees. By installing the brush drums at a certain angle, such as a 45-degree angle, the waste can be completely discharged.

[0017] In another embodiment, the cleaning device may include more than two cleaning units. Through this embodiment, the removal of glass mixed waste can be further improved.

[0018] In addition, the position of each brush drum on the corresponding transmission shaft can be adjusted, so that the influence on the conveyor belt can be balanced by adjusting the positions of the two sets of brush drums on the shaft.

[0019] According to the present utility model, the driving wheel can obtain kinetic energy by connecting to the main drum through a belt, and transmit the kinetic energy to the two sets of brush drums through components such as shafts and bevel gears, so that the two sets of brush drums obtain rotations in the direction opposite to the movement direction of the conveyor belt. By rotating the two sets of brushes in the direction of the conveyor belt, the waste falling inside the conveyor belt is swept out to both sides of the conveyor belt, thereby achieving the effect of automatically cleaning the conveyor belt.

[0024] Hereinafter, the technical solutions of the present invention will be further specifically described through embodiments in combination with the drawings. In the description, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the drawings is intended to explain the overall concept of the present invention and should not be construed as a limitation of the present invention.

[0025] Figure 1 The top view of an embodiment of a cleaning device for cleaning the glass mixture on the inner side of the conveyor belt of a cleaning belt conveyor is shown, where the inner side of the conveyor belt is the inner side of the return section of the conveyor belt.

[0026] The cleaning device 1 is used to clean the glass mixture 12 scattered on the inner side 10 of the conveyor belt of the cleaning belt conveyor (as shown in Figure 2 ), and includes a pulley unit 20, a power transmission unit 30, and a cleaning unit 40.

[0027] The pulley unit 20 includes two pulleys 21a, 21b and a belt 22 located between the two pulleys 21a, 21b. The first pulley 21a is attached to the main roller 11 of the conveyor belt and rotates together with the main roller 11 to obtain power from the main roller 11, and the other pulley 21b transmits the transmitted power to the power transmission unit 30.

[0028] One end of the power transmission unit 30 is connected to the pulley unit 20 for receiving and transmitting the power from the pulley unit 20.

[0029] Specifically, as shown in Figure 1 , the power transmission unit 30 includes two sets of bevel gears for power transmission.

[0030] The first set of bevel gears includes two bevel gears 31a and 31b. The first bevel gear 31a is rotatably and fixedly connected to the pulley unit 20 to receive power from the pulley unit 20. That is, the first bevel gear 31a has the same rotational angular velocity and rotational direction as the pulley unit 20. The second bevel gear 31b meshes with the first bevel gear 31a to receive power therefrom and is connected to one end of the first transmission shaft 42a of the cleaning unit 40. In this case, the rotational direction of the second bevel gear 31b and the first transmission shaft 42a is opposite to the rotational direction of the first bevel gear 31a.

[0031] The second set of bevel gears is used to transmit power in the cleaning unit 40. Specifically, in Figure 1 , the second set of bevel gears includes a third bevel gear 31c, a common gear 31d, and a fourth bevel gear 31e. The third bevel gear 31c is connected to the other end of the first transmission shaft 42a and transmits power to the common gear 31d. The common gear 31d meshes with the fourth bevel gear 31e connected to another transmission shaft of the cleaning unit 40, that is, the second transmission shaft 42b, to transmit the power from the first transmission shaft 42a to the second transmission shaft 42b, so that the transmission directions of two adjacent transmission shafts can be the same while transmitting power.

[0032] One end of the second transmission shaft 42b where no bevel gear is provided is connected to the bearing block 43, and the bearing block 43 is fixed to other parts of the cleaning device.

[0033] In addition, the parameters of each bevel gear are the same. By means of the coordinated operation of the bevel gear set, the rotational speeds and rotational directions of the two brush drums 41a and 41b are the same.

[0034] The cleaning unit 40 is connected to the power transmission unit 30 and is used to clean the glass mixture by means of the power from the power transmission unit 30. At the contact position between the cleaning unit 40 and the conveyor belt, the movement direction of the cleaning unit 40 (as shown by the curved arrow in Figure 1 ) is opposite to the movement direction T of the conveyor belt of the belt conveyor b to easily clean the glass mixture accumulated on the inner side of the conveyor belt.

[0035] The cleaning unit 40 may include two brush drums 41a and 41b and two transmission shafts 42a and 42b for fixing the brush drums 41a and 41b. The two brush drums 41a and 41b are both fixed to the two transmission shafts 42a and 42b by positioning bolts 44a and 44b.

[0036] As Figure 1As shown, the rotation directions of the two brush rollers 41a and 41b are the same, and at the contact positions of the two brush rollers 41a and 41b with the conveyor belt, they are b opposite to the movement direction T of the conveyor belt of the belt conveyor.

[0037] The two brush rollers 41a and 41b are inclined. Specifically, relative to the axis x where the common bevel gear 31d is located, the inclination angles of the two brush rollers 41a and 41b are the same but the inclination directions are opposite. As Figure 1 shown, the first brush roller 41a is located above the axis x, and the second brush roller 41b is located below the axis x.

[0038] Preferably, the inclination angles of the two brush rollers 41a and 41b are in the range of 30 degrees to 45 degrees, for example, preferably 45 degrees.

[0039] As Figure 1 shown, the two brush rollers 41a and 41b partially overlap at one end close to each other in the transverse direction perpendicular to the conveyor belt traveling direction T of the conveyor belt, and extend beyond the conveyor belt at the end far from each other. b And at the end far from each other, they both extend beyond the conveyor belt.

[0040] Figure 2 Shows Figure 1 a top view of the cleaning unit 40 of the cleaning device 1 shown in

[0041] As Figure 2 shown, the glass mixture 12 falling on the inner side 10 of the return conveyor belt can be accumulated into a material block 13 by the two brush rollers 41a and 41b. The material block 13 can be discharged outside the inner side 10 of the conveyor belt of the belt conveyor along the outer surfaces of the two inclined brush rollers 41a and 41b, so as to sweep the waste falling into the inner side 10 of the conveyor belt out of both sides of the conveyor belt, achieving the effect of automatically cleaning the conveyor belt.

[0042] Figure 3 Shows Figure 2 a cross-sectional view taken along line A-A in

[0043] As Figure 3 shown, the brush surfaces of the two brush rollers 41a and 41b are in close contact with the inner side 10 of the conveyor belt. The surfaces of the two brush rollers 41a and 41b are soft, so they can completely fit the uneven conveyor belt surface, eliminating the influence of the unevenness of the conveyor belt on the cleaning device. The brush roller surface has a certain elasticity, compensating for the up and down fluctuations during the operation of the conveyor belt, and can avoid the influence of the up and down fluctuations of the conveyor belt during operation on the cleaning device.

[0044] The first brush roller 41a includes a first roller body 411a and a first brush portion 412a attached to the first roller body 411a. The first brush portion 412a is made of materials known to those skilled in the art, such as felt, nylon, etc., to clean the glass mixture.

[0045] In addition, as Figure 3 shown, the first transmission shaft 42a has an elongated groove 45a on its surface, so that the position of the first brush roller 41a on the corresponding first transmission shaft 42a can be adjusted.

[0046] Although not shown in the figure, the second brush roller 41b and its corresponding second transmission shaft 42b are the same as Figure 3 shown. Therefore, the influence on the conveyor belt can be balanced by adjusting the positions of the two brush rollers 41a, 41b on the two transmission shafts 42a, 42b.

[0047] In addition, Figure 1 only one cleaning unit is shown in, however, it is known to those skilled in the art that the cleaning device 1 may include more than two cleaning units.

[0048] The component sizes and shapes in the embodiments are only exemplary, and those skilled in the art can think of setting them to other sizes or shapes.

[0049] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
