Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a micro-power material guiding trough. Background Art

[0002] The guide trough is an instrument used for guiding materials on a belt conveyor. Its main function is to concentrate the materials falling from the funnel to the middle of the conveyor belt, so as to prevent the materials from being scattered and the dust from leaking out. The guide trough is widely used in various manufacturing industries, such as food processing, chemical industry, metallurgy, pharmaceutical industry and construction industry, and is also used to transport cloth. The guide trough in the prior art is equipped with multiple curtains along its own transportation direction to form a pressure-equalizing dust-sealing and dust-reducing system, so that the dust can be depressurized, decelerated and settled, so that the cleaner airflow can flow out at the outlet of the guide trough. The multiple curtains are usually detachably installed on the outer box of the guide trough in a plug-in manner. As the use time increases, the dust isolated by the curtains will also be adsorbed on the curtains. Such unclean curtains will make the internal environment of the guide trough dirty. When the cloth passes through the unclean curtains, the dust will adhere to the cloth and pollute the cloth, so the staff needs to take out the curtains regularly for cleaning. However, it is very troublesome to take out and clean the curtains frequently, which is labor-intensive, time-consuming and labor-intensive. Summary of the invention

[0029] The conveying mechanism 2 includes a conveyor belt 21, and the conveyor belt 21 is driven by a conveying roller 22 (the conveyor belt 21 of the material guide trough is a relatively mature existing technology, so it will not be described in detail here). The conveyor belt 21 includes a horizontal portion 211 and two inclined portions 212 arranged on both sides of the horizontal portion 211. The two inclined portions 212 are gradually inclined from close to the horizontal portion 211 to away from the horizontal portion 211, so that a concave accommodating space is formed between the two inclined portions 212 and the horizontal portion 211 to hold the material. The two anti-overflow skirts 4 are respectively arranged corresponding to the two inclined portions 212, and are used to limit the material in the accommodating space described above without overflowing. Each of the anti-overflow skirts 4 is arranged along the conveying direction of the conveyor belt 21 and each of the anti-overflow skirts 4 includes a connecting portion 41 connected to the upper end wall of the box body 1 and an abutting portion 42 located at the lower end of the connecting portion 41, please refer to Figure 2 The connecting portion 41 is in an inverted L-shape, and the horizontal portion 211 of the connecting portion 41 is in close contact with the upper end wall inside the box body 1, and is detachably connected to the box body 1 through a plurality of bolts 43. A plurality of the bolts 43 are evenly spaced between the connecting portion 41 and the box body 1 along the length direction of the anti-overflow skirt 4, so that the force between each of the bolts 43 is evenly applied, and the connection between the connecting portion 41 and the box body 1 is more stable. The abutting portion 42 is inclined from top to bottom, from away from the horizontal portion 211 to close to the horizontal portion 211, and the lower end of the abutting portion 42 contacts the upper surface of the corresponding inclined portion 212.

The dust shield mechanism 3 includes a curtain 31, the width of which matches the distance between the two anti-overflow skirts 4 and the curtain 31 is installed at the lower end of the first protrusion 14. The lateral sides of the curtain 31 are in contact with the opposite sides of the two anti-overflow skirts 4 respectively, and the lower end of the curtain 31 is processed with a bevel to match and fit with the surfaces of the abutment portion 42 and the inclined portion 212 respectively, and the bottom edge of the curtain 31 fits with the horizontal portion 211.

[0031] The dust blocking mechanism 3 further includes a cleaning member 32 for cleaning the curtain 31. The cleaning member 32 moves vertically along the curtain 31 to clean the curtain 31. The cleaning member 32 is mounted at the lower end of the second protrusion 15. The cleaning member 32 includes a brush 321 and a driving component 322 for driving the brush 321 to move vertically. Figure 5 and Figure 6The brush 321 faces the curtain 31 and includes a first segment 3211 and two second segments 3212 located at both ends of the first segment 3211, and the two second segments 3212 can be extended relative to the first segment 3211. When the first segment 3211 and the two second segments 3212 are extended, the sum of the lengths of the first segment 3211 and the two second segments 3212 matches the distance between the two anti-overflow skirts 4, and the length of the brush 321 in a fully retracted state matches the width of the horizontal portion 211. Specifically, the two second segments 3212 are respectively located at both ends of the first segment 3211 and are slidably connected to the first segment 3211, the outer diameter of each second segment 3212 is greater than the outer diameter of the first segment 3211, and the two second segments 3212 are both provided with a slide groove 3213 along the length direction. The slide groove 3213 penetrates the corresponding second segment 3212 in the direction close to the curtain 31, and the slide groove 3213 also penetrates the second segment 3212 in the direction close to the first segment 3211. The size of the slide groove 3213 matches the first segment 3211 so that the first segment 3211 can slide inside. A first limiting assembly is provided between each second segment 3212 and the first segment 3211. The first limiting assembly includes a first limiting groove 3214 and a first limiting block 3215. The first limiting block 3215 is T-shaped and is installed on the side of the first segment 3211 away from the curtain 31, and the first limiting block 3215 is located at a position on the first segment 3211 close to the end in the length direction. The first limiting groove 3214 is provided on a side wall of the slide 3213 away from the curtain 31, and the cross section of the first limiting groove 3214 is T-shaped to match the first limiting block 3215, and the first limiting block 3215 is slidably connected to the first limiting groove 3214. The first segment 3211 is provided with a groove, and the groove passes through the first segment 3211 in the direction close to the curtain 31. An air pump 3216 is provided in the groove, and the air pump 3216 is connected to a collection box (not shown in the figure) located outside the box body 1 through a hose. A card slot 3217 is recessed upward at the lower end of the second protrusion 15, and the card slot 3217 passes through the second protrusion 15 along the conveying direction of the conveyor belt 21. The width of the card slot 3217 matches the width of the brush 321 so that the brush 321 can be clamped therein. A second limiting component is provided between the brush 321 and the card slot 3217. The second limiting assembly includes a second limiting block 3218 and a second limiting groove 3219 .There are two second limit blocks 3218, and the two second limit blocks 3218 are respectively located on the end faces of the two second segments 3212 that are away from each other. The cross section of the second limit block 3218 is trapezoidal, that is, the outer diameter of the end of the second limit block 3218 close to the corresponding second segment 3212 gradually decreases. There are also two second limit grooves 3219, and the two second limit grooves 3219 are respectively opened on the two side walls of the slot 3217, that is, the two second limit grooves 3219 are respectively opened corresponding to the two second limit blocks 3218, and the second limit grooves 3219 are trapezoidal matching the second limit blocks 3218, and the second limit blocks 3218 are slidably connected to the corresponding second limit grooves 3219. The second limit assembly can make the brush 321 more stable in the slot 3217.

[0032] Please refer to Figure 7 The driving assembly 322 is arranged in the second protrusion 15, and includes a rotating motor 3221, a rotating shaft 3222 and a connecting rope 3223. The number of the rotating motors 3221 is two, and the two rotating motors 3221 are installed in the second protrusion 15. Specifically, the two rotating motors 3221 are respectively arranged at positions corresponding to the two second sections 3212. The output shafts of the rotating motors 3221 extend horizontally, and each output shaft is connected to a rotating shaft 3222, and a connecting rope 3223 is wound around each rotating shaft 3222. One end of the connecting rope 3223 is wound around the corresponding rotating shaft 3222, and the other end extends vertically downward and is fixedly connected to the end of the upper end surface of the corresponding second section 3212 away from the first section 3211.

[0033] One embodiment of a micro-powered material guide trough of the present invention works as follows: the material to be transported is put into the box 1 through the feed pipe 11, and the material falls onto the conveyor belt 21, and the conveyor belt 21 transports the material. In this process, the material will pass through the barrier curtain 31, and the barrier curtain 31 will block the dust raised by the material in the box 1 to prevent the dust from flying. At the same time, the barrier curtain 31 will brush off some of the dust on the material. After a period of time, dust will accumulate on the barrier curtain 31, and it needs to be cleaned.

[0034] It should be emphasized that if the conveying direction of the conveyor belt 21 is from the first side of the curtain 31 to the second side of the curtain 31, then each brush 321 is arranged on the first side of the curtain 31. In the initial state, the brush 321 is located at the highest point of its own travel, that is, the brush 321 is located in the card slot 3217, the two second limit blocks 3218 are respectively located in the two second limit slots 3219, and the two second sections 3212 are extended relative to the first section 3211. When cleaning is required, the rotary motor 3221 is started to rotate forward, and the two rotary motors 3221 in the same group of driving components 322 rotate synchronously, and the two connecting ropes 3223 are loosened at the same time, so that the brush 321 falls due to its own gravity, and the curtain 31 is continuously brushed and cleaned during the falling process. When the brush 321 falls to a position corresponding to the abutment portion 42, the two second sections move toward each other due to the influence of the inclined surfaces of the two abutment portions 42 on both sides, that is, the two second sections shrink toward the first section due to the contact of the two abutment portions 42. When the brush 321 falls to a position corresponding to the inclined section 212, the two second sections move toward each other due to the influence of the inclined surfaces of the two inclined sections 212 on both sides. That is, due to the sliding connection between the two second sections and the first section, the width of the brush 321 can change with the inclination of the overflow prevention skirt 4 and the conveyor belt 21, and the brush 321 can clean the entire curtain 31. Then the rotating motor 3221 is reversed, and at this time, the two connecting ropes 3223 are retracted at the same time, and the brush 321 is lifted upward. Since the two connecting ropes 3223 are connected to the ends of the second segments 3212 , when there is no longer abutment between the two ends of the two second segments 3212 by the abutment portions 42 or the inclined portions 212 , the two second segments 3212 will return to their initial positions under the pulling of the two connecting ropes 3223 .

[0035] During the movement of the brush 321, the air extractor 3216 is always in operation to suck out the dust swept by the brush 321. Under the operation of the cleaning member 32, the staff only needs to clean the dust collection box in time, and does not need to frequently take out the curtain 31 for cleaning. At the same time, the cleaning member 32 is arranged on the end cover 13 like the curtain 31, so that the staff can take it out for maintenance and other operations.
