Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a belt cleaning mechanism for belt conveyors. Background Art

[0002] During the material transportation process, there are often some residues attached to the conveyor belt, which will affect the transportation efficiency and the quality of the goods. Therefore, in order to reduce the adverse effects of these residues on the transportation of goods, the conveyor belt must be cleaned regularly.

[0003] The existing cleaning method is to install a scraper on the conveyor belt, drive the conveyor belt to move relative to the conveyor belt, and scrape off the dust adhering to the surface of the conveyor belt; however, since the scraper is fixed on the conveyor belt, its cleaning function can only be performed at a specific position, which requires the conveyor belt to rotate for multiple circles to ensure that the dust on the entire surface is removed, affecting the cleaning efficiency of the conveyor belt, and the residue on the scraper may re-adhere when it contacts the conveyor belt again, affecting the cleaning effect. In view of these problems, a belt cleaning mechanism for a belt conveyor is proposed. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a belt cleaning mechanism for a belt conveyor, which can fully abut against the surface of the conveyor belt, efficiently scrape the residues attached to the surface of the conveyor belt, improve the cleaning efficiency and optimize the cleaning effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A belt cleaning mechanism for a belt conveyor is provided, comprising a fixed frame, a positioning slide and a rotating seat, wherein the fixed frame is mounted on the outer side of the conveyor belt, the positioning slide is slidably mounted on the fixed frame, a rotating seat is rotatably mounted in the middle of the positioning slide, a second motor for driving the rotating seat to rotate is mounted on the positioning slide, and a plurality of brush bundles are connected to the bottom of the rotating seat.

[0007] Furthermore, an oscillating sleeve is rotatably mounted on the outer side of the rotating seat, a counterweight is detachably mounted on the side of the oscillating sleeve, and a plurality of plug posts are fixedly mounted on the inner side of the oscillating sleeve, and the plug posts pass through the gaps between the plurality of bristle bundles.

[0008] Furthermore, the fixing frame is mounted on the upper side or the lower side of the conveyor, and the conveyor belt is installed on the conveyor.

[0009] Furthermore, the length of the bristle bundle gradually shortens along the direction extending from the center of the rotating seat to the edge of the rotating seat.

[0010] Furthermore, a groove is provided on the side of the rotating seat, a spring is fixedly mounted on the counterweight, and the other end of the spring is plugged and fixedly connected in the groove.

[0011] Furthermore, the bristle bundle is formed by bundling a plurality of bristles together and bonding the rear ends thereof.

[0012] Furthermore, the cross-section of the bristle bundle is circular.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The belt cleaning mechanism for a belt conveyor of the utility model utilizes a rotating rotating seat to drive multiple brush bundles to sweep across the surface of the conveyor belt, and efficiently scrapes the residues attached to the surface of the conveyor belt, so that the residues are easily detached from the surface of the conveyor belt.

[0015] 2. The belt cleaning mechanism for the belt conveyor in the example of the utility model has an oscillating sleeve rotatably installed on the outer side of the rotating seat to control the reciprocating rotation of the rotating seat. At the moment when the rotating seat switches the rotation direction, the oscillating sleeve rotates relative to the rotating seat under the action of the deadweight and the moving inertia of the counterweight, and the multiple bristle bundles are vibrated by the plug-in column to make the residues easily detached from the bristle bundles, thereby maintaining the cleanliness of the bristle bundles.

[0016] 3. In the belt cleaning mechanism for a belt conveyor of the utility model, the length of the bristle bundle at the center of the rotating seat is longer than the length of the bristle bundle at the edge of the rotating seat, thereby improving the effect of cleaning the surface of the conveyor belt with a concave middle portion.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, this embodiment provides a belt cleaning mechanism for a belt conveyor, including a fixed frame 11, a positioning slide 12 and a rotating seat 21, the fixed frame 11 is mounted on the outside of the conveyor belt 1, the positioning slide 12 is slidably installed on the fixed frame 11, the rotating seat 21 is rotatably installed in the middle of the positioning slide 12, a second motor 24 for driving the rotating seat 21 to rotate is installed on the positioning slide 12, a plurality of bristle bundles 22 are connected to the bottom of the rotating seat 21, the cross-section of the bristle bundle 22 is circular, and the bristle bundle 22 is composed of a plurality of bristles bundled together and bonded at the rear ends.

[0033] A screw rod 13 is rotatably mounted on the fixing frame 11 . The screw rod 13 is connected to the positioning slide 12 via threaded transmission. A first motor 14 for driving the screw rod 13 to rotate is mounted on the fixing frame 11 .

[0034] When the surface of the conveyor belt 1 is cleaned, the first motor 14 and the second motor 24 are started at the same time to drive the rotating seat 21 to rotate, and the positioning slide 12 is controlled to slide on the fixed frame 11, so that the brush bundle 22 can efficiently scrape the residue attached to the surface of the conveyor belt, making it easy for the residue to detach from the surface of the conveyor belt.

[0035] In order to increase the cleanliness of the bristle bundles 22, an oscillation sleeve 31 is rotatably installed on the outer side of the rotating seat 21, and a counterweight 34 is detachably installed on the side of the oscillation sleeve 31, and a plurality of plug posts 32 are fixedly installed on the inner side of the oscillation sleeve 31, so that the plug posts 32 pass through the gaps between the plurality of bristle bundles 22 to control the reciprocating rotation of the rotating seat 21. At the moment when the rotating seat 21 switches the rotation direction, the oscillation sleeve 31 rotates relative to the rotating seat 21 under the action of its own weight and moving inertia of the counterweight 34, so that the plug posts 32 vibrate the plurality of bristle bundles 22, so that the residues can be easily detached from the bristle bundles 22, thereby maintaining the cleanliness of the bristle bundles 22 and preventing the residues from re-adhering to the surface of the conveyor belt 1.

[0036] Among them, the counterweight 34 can be set to two or more. When two counterweights 34 are used, the two counterweights 34 are symmetrically installed on the sides of the oscillation sleeve 31. By increasing the number of counterweights 34, the vibration effect of the plug 32 on multiple bristle bundles 22 is increased.

[0037] Since the pins 32 pass through the gaps at the roots of the bristle bundles 22 , the pins 32 will not slip out of the gaps of the bristle bundles 22 .

[0038] In order to increase the effect of the equipment on cleaning the surface of different types of conveyor belts 1, the length of the bristle bundle 22 is gradually shortened along the direction extending from the center of the rotating seat 21 to the edge of the rotating seat 21. In the process of surface cleaning the conveyor belt 1 with a concave middle part, the end of the bristle bundle 22 located at the edge of the rotating seat 21 can fully contact the edge of the conveyor belt 1 and efficiently scrape the residue attached thereon.

[0039] Embodiment 2:

[0040] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4-6 As shown, in this embodiment, a groove 23 is provided on the side of the rotating seat 21, and a spring 35 is fixedly installed on the counterweight 34. The other end of the spring 35 is inserted and fixedly connected in the groove 23 to control the reciprocating rotation of the rotating seat 21. At the moment when the rotating seat 21 switches the rotation direction, under the action of the deadweight 34 and the moving inertia, the oscillation sleeve 31 rotates relative to the rotating seat 21, and a bending force is applied to the spring 35. During the switching process of the rotation direction of the rotating seat 21, the spring is reset, and the oscillation sleeve 31 rotates in the opposite direction relative to the rotating seat 21. Through the above scheme, the driving effect of the plug 32 on the multiple bristle bundles 22 is further increased.

[0041] In order to increase the detachability of the spring, discs are fixedly connected at both ends of the spring 35, and the two discs are detachably fixedly connected to the counterweight 34 and the inner wall of the groove 23 via fasteners.
