Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor cleaning equipment, in particular to a belt conveyor cleaning device. Background Art

[0002] Belt conveyor is a machine that uses belt as carrier for transportation. It is widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing and food.

[0003] When a belt conveyor is transporting sticky materials, some of the materials will remain on the belt surface due to the strong adhesion of the materials. This part of the materials will adhere to the belt surface for a long time, which will not only lead to poor hygiene at the transportation site, but also the possibility of mold on the adhered materials. This part of the mold will contaminate the subsequently transported materials. Therefore, a cleaning device for a belt conveyor is proposed to solve the above-mentioned problems.

[0033] See also Figure 1-Figure 3 , a cleaning device for a belt conveyor, comprising:

[0034] A fixing seat 1, wherein the fixing seat 1 comprises a seat body 11, and an upper surface of the seat body 11 is provided with a mounting hole and a guide blind hole 12, wherein the guide blind hole 12 is a rectangular blind hole;

[0035] A movable frame 2 is arranged above the fixed seat 1 and extends to the inside of the fixed seat 1. The movable frame 2 includes a frame body 21. The frame body 21 is an L-shaped frame body. A movable vertical rod 22 is arranged at the bottom end of the frame body 21. The movable vertical rod 22 is a rectangular rod. The movable vertical rod 22 extends to the inside of the guide blind hole 12.

[0036] A support spring 6, which is arranged between the fixed seat 1 and the movable frame 2;

[0037] Based on the above, the fixed seat 1 can be fixed under the conveyor belt by screws. At this time, the movable frame 2 can move vertically along the direction of the guide blind hole 12, and the movable frame 2 makes the inner gear housing 4 fit tightly with the lower surface of the belt under the action of the elastic force of the supporting spring 6.

[0038] like Figure 2-Figure 5 as well as Figure 7 As shown, the planetary gear is arranged on the opposite side of the movable frame 2 and includes a fixed cover 3, an internal gear housing 4, a main gear 7, a connecting shaft 8 and a driven gear 9, wherein:

[0039] A fixed cover 3, which is arranged on the outside of the inner tooth housing 4, and the fixed cover 3 is arranged on the opposite side surface of the frame 21. A connecting shaft 8 is arranged on the opposite side surface of the fixed cover 3, and a driven gear 9 is arranged on the outside of the connecting shaft 8. The driven gear 9 is meshed with the inner tooth housing 4. The fixed cover 3 includes a hollow cover body 31, and a hemispherical groove is arranged on the inner wall of the hollow cover body 31. A ball 32 is arranged inside the hemispherical groove, and the ball 32 contacts the outer surface of the inner tooth housing 4;

[0040] The inner tooth housing 4 extends to the interior of the fixed cover 3, and the inner wall of the inner tooth housing 4 is provided with a toothed annular surface;

[0041] A driven gear 9 connected to the fixed cover 3 via a connecting shaft 8;

[0042] A main gear 7 is disposed between the driven gears 9. The main gear 7 includes a gear body 71. Two ends of the gear body 71 are respectively provided with a connecting hole 72 and a prism hole 73. The connecting hole 72 and the prism hole 73 are communicated with each other. The gear body 71 is meshed with the driven gear 9.

[0043] Based on the above, the planetary gear plays a role in transmission and changing the direction of movement. The fixed cover 3 and the frame 21 are fixed to each other, so the fixed cover 3 is always in a fixed state. The internal tooth housing 4 extends to the inside of the fixed cover 3 and contacts with the ball 32. At this time, the internal tooth housing 4 can rotate inside the fixed cover 3. When the internal tooth housing 4 rotates, it drives the driven gear 9 to rotate with the connecting shaft 8 as the center. When the driven gear 9 rotates, it drives the main gear 7 to rotate. At this time, the main gear 7 drives the cleaning roller 5 to rotate, and the direction of rotation of the cleaning roller 5 is opposite to the direction of rotation of the internal tooth housing 4.

[0044] like Figure 2 , Figure 3 as well as Figure 6 As shown, the cleaning roller 5 is arranged between the planetary gears and connected to the main gear 7 through a nut. The cleaning roller 5 includes a roller body 51. Both ends of the roller body 51 are provided with connecting columns 52, positioning prisms 53 and threaded columns 54 from near to far. The positioning prisms 53 match the prism holes 73. The roller body 51 includes a cylindrical roller body. The outer surface of the cylindrical roller body is provided with a cleaning scraper.

[0045] Based on the above, the cleaning roller 5 is connected to the main gear 7 through a nut. When the main gear 7 rotates, the cleaning roller 5 is driven to rotate. At this time, the cleaning scraper can scrape the material stuck on the belt surface. The positioning prism 53 and the prism hole 73 cooperate with each other, so that when the main gear 7 rotates, the cleaning roller 5 can be driven to rotate together. The setting of the threaded column 54 enables the cleaning roller 5 to be connected to the main gear 7 through a nut.

[0046] In actual use, the fixing seat 1 is fixed to the surface of the belt conveyor by screws, so that the device is located below the belt. The inner gear housing 4 is tightly fitted to the lower surface of the belt under the action of the upward elastic force through the cooperation between the fixing seat 1, the movable frame 2 and the supporting spring 6. When the belt conveyor is working, the belt drives the inner gear housing 4 to rotate.

[0047] When the inner gear housing 4 rotates, the driven gear 9 is driven to rotate. Since the driven gear 9 is connected to the fixed cover 3 through the connecting shaft 8, and the fixed cover 3 is connected to the movable frame 2, the fixed cover 3 is in a fixed state, so that the driven gear 9 can only rotate with the connecting shaft 8 as the center of the circle, and there is no possibility of circular motion. At this time, the driven gear 9 is meshed with the toothed annular surface inside the inner gear housing 4, so the rotation direction of the driven gear 9 is consistent with the rotation direction of the inner gear housing 4;

[0048] When the driven gear 9 rotates, it drives the main gear 7 to rotate. At this time, the rotation direction of the main gear 7 is opposite to that of the driven gear 9 and the inner gear housing 4, that is, the rotation direction of the main gear 7 is consistent with the movement direction of the belt. Since the main gear 7 is below the belt, the movement directions of the main gear 7 and the side close to the belt are opposite, that is, since the cleaning roller 5 rotates under the drive of the main gear 7, the rotation direction of the cleaning roller 5 is consistent with the direction of the main gear 7, so that the movement directions of the cleaning roller 5 and the contact surface of the belt are opposite, so that the cleaning scraper can reversely scrape the materials stuck to the belt surface;

[0049] The cleaning device drives the cleaning roller 5 to roll by utilizing the kinetic energy of the belt during transportation, and makes the cleaning roller 5 consistent with the movement direction of the belt under the action of the planetary gear, so that the movement direction of the cleaning roller 5 and the contact surface of the belt are opposite, thereby achieving the function of scraping off sticky materials and effectively avoiding the negative impact caused by material sticking.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
