[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1:

[0031] Please combine Figures 1-10 The squirrel-cage screw roller of this embodiment includes a rotating body 1, a receiving mechanism 2 arranged inside the rotating body 1, and a cleaning mechanism 3 arranged outside the rotating body 1;

[0032] The rotating body 1 includes a cylindrical body 11 with an annular structure. The cylindrical body 11 is penetrated by an array of channels 12. A front cover plate 13 is fixedly connected to the inner ring of one end of the cylindrical body 11. A screw 14 is fixedly sleeved on the end cover plate 13. A rear cover plate 15 is fixedly sleeved on the screw 14 at the other end of the cylindrical body 11. A propulsion blade 16 with a spiral structure is fixedly sleeved on the outer ring of the screw 14 and is provided between the rear cover plate 15 and the front cover plate 13.

[0033] The receiving mechanism 2 includes a baffle 21 that is rotatably sleeved on the outer ring of the rear end cover plate 15, and the baffle 21 is rotatably connected to the inner ring of the cylinder 11. A receiving plate 23 with an arc-shaped structure is fixedly connected to the side of the baffle 21 close to the front end cover plate 13. A discharge channel 22 passes through the bottom of the receiving plate 23. The side of the receiving plate 23 away from the supporting plate 23 is fixedly connected to an array of overlapping plates 24 for fixing the receiving mechanism 2 and for fixing the cleaning mechanism 23.

[0034] The cleaning mechanism 3 includes a rear end baffle 31 sleeved with the overlapping plate 24 and a front end baffle 34 provided on the front side of the front cover 13. A scraper 32 is fixedly connected between the rear end baffle 31 and the front end baffle 34 and contacts the outside of the cylinder 11. A guide plate 33 is provided at the bottom of the scraper 32 and contacts the outside of the cylinder 11. The guide plate 33 is fixedly connected to the rear end baffle 31 and the front end baffle 34. A connecting plate 35 for maintaining the state of the cleaning mechanism 3 is detachably connected to one side of the front end baffle 34.

[0035] When using the roller, the screw 14 is connected to the frame of the conveying equipment through the bearing seat and is connected to the motor that drives it to rotate. The lap plate 24 is fixed to the frame of the conveying equipment by means of mounting bolts. When fixing, the state of the receiving plate 23 is adjusted so that the receiving plate 23 opens upward, and then the cleaning mechanism 3 is installed on the outside of the cylinder 11. When the motor is started, it drives the screw 14 to rotate, and then the rotating body 1 rotates as a whole. At this time, the rotating body 1 can drive the conveyor belt sleeved on the outside thereof to move, thereby realizing the material conveying operation. Since the lap plate 24 is fixed to the frame, the rotating body 1 rotates relative to the receiving mechanism 2, and the conveyed bagged material is removed from the packaging bag. After leakage, the material falls into the cylinder 11 from the channel 12 of the cylinder 11, preventing the material from adhering to the inner side of the conveyor belt, and also preventing the material from adhering to the outer surface of the cylinder 11, causing caking on the surface of the cylinder 11, thereby affecting the force transmission between the cylinder 11 and the conveyor belt, and also avoiding damage to the conveyor belt. The material entering the cylinder 11 from the channel 12 is received by the receiving plate 23, and the receiving plate 23 collects the material. At the same time, as the screw 14 rotates, the pushing blade 16 moves accordingly, and the pushing blade 16 moving relative to the receiving plate 23 pushes the material to the side of the discharge channel 22, thereby pushing the collected material out of the cylinder 11, which is convenient for the subsequent re-collection operation of the material.

[0036] At the same time, when the cylinder 11 moves relative to the cleaning mechanism 3, the scraper 32 can scrape off the material on the surface of the cylinder 11 that has not completely entered the interior of the cylinder 11. The material scraped off from the outer surface of the cylinder 11 is further guided to the surface of the cylinder 11 by the guide plate 33 and enters the cylinder 11 along the channel 12, thereby realizing the complete cleaning and collection operation of the material on the outer surface of the cylinder 11.

[0037] Example 2:

[0038] Based on Example 1, this embodiment has further improvements in that: the rear end baffle 31 is penetrated by a docking groove 311 which is sleeved with the lap plate 24, and the rear end baffle 31 is provided with a threaded hole connected to the docking groove 311, and the threaded hole is threaded with a locking screw to facilitate the connection between the lap plate 24 and the rear end baffle 31.

[0039] A groove 1 351 with an arc-shaped structure is provided on one side of the connecting plate 35 close to the front end baffle 34, and plug-in plates 352 fixed to the front end baffle 34 are installed on both sides of the opening of the groove 1 351. A groove 2 341 with an arc-shaped structure is provided on one side of the front end baffle 34 close to the connecting plate 35, and an extension groove 342 located at the end of the front end baffle 34 is provided on both sides of the opening of the groove 2 341, and the extension groove 342 is docked with the plug-in plate 352. The inner concave surfaces of the groove 2 341 and the groove 1 351 are both slidably sleeved with balls distributed in an array along their axes. The connecting plate 35 is sleeved on the outer ring of the screw 14 close to the front end baffle 34, thereby ensuring that the scraper 32 and the guide plate 33 of the cleaning mechanism 3 are in contact with the outer surface of the cylinder 11.

[0040] Both sides of the inner concave surface of the receiving plate 23 are provided with inclined guide grooves, and the diameter of the receiving plate 23 is consistent with the diameter of the pushing blade 16.

[0041] The lap plate 24 is provided with a fixing hole for installation and connection, and the fixing hole is threadedly sleeved with a mounting bolt, and the receiving plate 23 is slidably sleeved with the inner wall of the cylinder 11.

[0042] An annular slot is formed on the outer ring of the rear end cover 15 , and a retaining spring is connected to the slot to limit the relative sliding of the receiving mechanism 2 .

[0043] The side of the rear end cover plate 15 close to the front end cover plate 13 and the side of the baffle plate 21 close to the front end cover plate 13 are located on the same plane. The distance between the front end cover plate 13 and the rear end cover plate 15 is consistent with the length of the connecting plate 23, and the end of the connecting plate 23 is in conflict with the side of the front end cover plate 13.

[0044] The channels 12 distributed along the circumferential direction of the cylinder 11 are staggered front to back, and the channels 12 are distributed between the front cover plate 13 and the rear cover plate 15 .

[0045] The present invention adopts a combined design with a simple structure and easy installation and operation. It can use the power of the cylinder's rotation to clean the material deposited on the cylinder surface, avoid the material adhering to the outer surface of the cylinder and the material agglomeration, thereby reducing the probability of material adhering to the inner side of the conveyor belt, reducing the damage of the roller to the conveyor belt, ensuring smooth and efficient transmission between the roller and the conveyor belt, and can push and collect the material entering the interior of the roller, making it convenient for operators to collect leaked materials.

[0046] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
