Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a tube belt conveyor with a self-cleaning roller. Background Art

[0002] A pipe belt conveyor is a tubular belt conveyor. It is a belt conveyor with a conveyor belt curled into a tube shape. The conveyor belt is surrounded by rollers and curled into a tube shape. The conveyor belt is overlapped and spliced ​​to achieve tubular closure, thereby ensuring that materials will not be scattered on the conveying line and will not be affected by the external environment due to wind or rain, achieving leak-free and closed transportation.

[0003] As attached Figure 6 The figure shows a cross-sectional drawing of the middle tubular section of the currently used pipe belt conveyor. The equipment includes a frame 1, a roller body 2, a roller bracket 3 and a tubular belt 4; the roller body 2 is installed on the roller bracket 3, and is used to position and support the tubular belt 4 to move on the roller body 2. During the operation of the equipment, since the outer wall of the tubular belt 4 and the outer wall of the roller body 2 have a small contact area, it is necessary to rely on the roller body 2 and the outer wall of the tubular belt 4 to maintain good friction, so as to ensure that the rolling speed of each roller body 2 is consistent, thereby reducing the probability of torsional deflection of the tubular belt 4.

[0004] However, it is found in actual work that the tubular belt 4 is often used to transport materials such as granular powder. During the transportation process, the area around the roller body 2 is inevitably filled with floating dust, which adheres and accumulates on the surface of the roller body 2 to form a smooth covering layer, isolating the friction contact of the rubber surface of the roller body 2, thereby reducing the contact friction between the roller body 2 and the tubular belt 4, indirectly affecting the operating stability of the tubular belt 4.

[0005] Based on this, the utility model designs a tube belt conveyor with self-cleaning rollers to solve the above problems. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0025] See also Figure 1-3 The accompanying drawings of this embodiment show the middle section of a pipe belt conveyor; the utility model provides a technical solution:

[0026] A self-cleaning roller pipe belt conveyor includes a frame mounting plate 10, a through-hole 20 formed on the frame mounting plate 10, a tubular conveyor belt 30 extending through the through-hole 20, and three sets of belt roller assemblies 40 disposed on the front and back sides of the frame mounting plate 10, respectively. The outer wall of the tubular conveyor belt 30 abuts between the three sets of belt roller assemblies 40, and the three sets of belt roller assemblies 40 on the front and the three sets of belt roller assemblies 40 on the back of the frame mounting plate 10 are staggered. The complete tubular conveyor belt 30 is an annular structure, one end of which is provided with a belt drive device, which drives the tubular conveyor belt 30 in a circular motion. The tubular conveyor belt 30 is partially unfolded at both ends. When it reaches the middle section, the edges on both sides gradually reel in toward the middle until it forms a circular tube, which facilitates the placement and scattering of conveyed materials.

[0027] like Figure 4 As shown, the belt roller assembly 40 includes a roller bracket 41 and a roller body 42 , and a reel-type flexible dust removal brush 43 is detachably provided on the roller bracket 41 .

[0028] Specifically, such as Figure 5 As shown, the roller bracket 41 includes a U-shaped bottom plate 411, and side plates 412 are symmetrically arranged on both sides of the U-shaped bottom plate 411. An open groove 413 is arranged at the top of the side plate 412, and a limiting pressure plate 414 is arranged on the outer side of the side plate 412, which is connected and locked with the side plate 412 by bolts; a roller shaft 421 is arranged inside the roller body 42, and both ends of the roller shaft 421 are inserted into the open grooves 413 of the side plates 412 on both sides; bearings are provided inside the roller body 42, and after the two ends of the roller shaft 421 are fixedly installed, the roller body 42 is supported to roll freely. When loading and unloading the roller body 42, it is only necessary to remove the limiting pressure plate 414 to directly remove the roller body 42 along the direction of the open groove 413; further, the open groove 413 is facing the central axis direction of the tubular conveyor belt 30, thereby ensuring that the loading and unloading operation of the roller body 42 is not affected by the position interference of the tubular conveyor belt 30, and facilitating the maintenance of the roller body 42.

[0029] Specifically, such as Figure 5 As shown, the roller bracket 41 includes a U-shaped base plate 411, with external hexagonal columns 415 fixedly provided on both sides of the U-shaped base plate 411, and fixing nuts 416 are screwed to the ends of the external hexagonal columns 415; the reel-type flexible dust removal brush 43 includes a flexible elastic cloth belt 431, such as an elastic band with a built-in rubber band, and flexible bristles 432 are densely distributed on the flexible elastic cloth belt 431. The ends of the flexible bristles 432 are respectively clamped and fixed on a reel barrel 433. The reel barrel 433 has an internal hexagonal hole 434 extending through the inner cavity thereof and matching the external hexagonal column 415.

[0030] The reel-type flexible dust removal brush 43 is actually a brush row structure arranged on the outside of the roller body 42. It is characterized by its soft elasticity. When installing the reel-type flexible dust removal brush 43, first remove the fixing nut 416 and stretch the flexible elastic cloth belt 431 so that the spacing between the inner hexagonal holes 434 on both sides is consistent with the spacing between the outer hexagonal columns 415 on both sides. Then, the reel tube 433 can be put on the outer hexagonal columns 415 and locked with the fixing nut 416.

[0031] After installation, the reel-type flexible dust removal brush 43 is located at the bottom of the roller body 42, and the top of the flexible bristles 432 is in contact with the roller body 42. When the roller body 42 rolls, the flexible bristles 432 can use the contact friction to remove dust from the surface of the roller body 42, so that the reel-type flexible dust removal brush 43 and the wall of the roller body 42 can maintain good friction, ensuring that the rolling speed of each roller body 42 is consistent, thereby reducing the probability of twisting and deflection of the tubular conveyor belt 30; in order to ensure cleaning efficiency, the top surface of the flexible bristles 432 on the flexible elastic cloth belt 431 is a circular arc groove surface structure that matches the wall of the roller body 42, which improves the cleaning effect by increasing the contact surface.

[0032] Since the flexible elastic cloth belt 431 is an elastic structure, and the tension of the flexible elastic cloth belt 431 can be changed by changing the tensioning length during installation, when implementing the plan in practice, the tension of the flexible elastic cloth belt 431 can be adjusted according to the equipment use environment, the hardness of the flexible bristles 432, the vibration amplitude frequency required for its own dust removal, and the contact size between the flexible bristles 432 and the outer wall of the roller. When adjusting, the flexible elastic cloth belt 431 can be wound or released by using the reel 433.

[0033] Since the individual reel-type flexible dust removal brushes 43 are arranged below the roller body 42, the dust falling from the roller body 42 falls directly on the flexible elastic cloth belt 431, and dust accumulation is formed over time. In the present embodiment, since the flexible elastic cloth belt 431 is an elastic structure, further, the wall surface of the roller body 42 is provided with a fishing net-like anti-slip ridge 422. In addition to increasing the contact friction, since the bristles at the top of the flexible brush 432 abut against the outer wall of the roller body 42 when working, the fishing net-like anti-slip ridge 422 can further cause the flexible elastic cloth belt 431 to generate a certain frequency of vibration, thereby shaking off the dust falling on the flexible elastic cloth belt 431, thereby realizing automatic dust removal.

[0034] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
