Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to an intermediate drive conveyor line. Background Technology

[0002] Intermediate drive belt conveyors mainly consist of a conveyor belt, drive unit, intermediate drive unit, support unit, idlers, and tensioning device. The intermediate drive unit applies driving force along the entire length of the conveyor belt, giving it stronger traction, thus improving conveying capacity and stability, reducing belt skipping, and effectively minimizing belt tension fluctuations due to the uniform and stable driving force applied. This reduces equipment failure rate and maintenance difficulty.

[0003] The existing intermediate drive belt conveyor has its drive roller located in the middle of the lower belt, which makes it inconvenient to bend the lower belt. When material falls to the inside of the lower conveyor belt due to its proximity to the edge of the conveyor belt, it is inconvenient for the conveyor belt to bend and shape the material directly to discharge it. As a result, the material will be carried by the lower conveyor belt to the roller, causing the material to get stuck between the roller and the conveyor belt, which will accelerate the wear of the conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide an intermediate drive conveyor line that prevents materials from getting stuck between the conveyor belt and the roller, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intermediate drive conveyor line, including a frame, a roller rotatably mounted on the frame, a conveyor belt fitted on the outer side of the roller, and a fan duct fixedly embedded in the frame, with the fan duct close to the roller. A conduit communicating with the fan duct is installed at the end of the fan duct away from the frame, and the end of the conduit away from the fan duct is fixedly connected to a vacuum cleaner; a cleaning structure for cleaning materials inside the frame, the cleaning structure being installed inside the frame and on the same horizontal line as the fan duct; and a scraping structure for cleaning materials adhering to the surface of the roller, the scraping structure being installed above the cleaning structure.

[0006] Preferably, the cleaning structure includes an impeller rotatably mounted inside the air duct, the impeller being able to rotate under the drive of airflow, and a rotating shaft being fixedly embedded at the end of the impeller away from the duct.

[0007] Preferably, the rotating shaft is rotatably connected to the frame via a bearing, the bearing reducing the friction between the rotating shaft and the frame, and a roller brush is fixedly sleeved on the outer side of the rotating shaft.

[0008] Preferably, the roller brush is in active contact with the inner wall of the conveyor belt, and the direction of rotation of the roller brush is opposite to that of the conveyor belt, so that the roller brush can prevent the material from being conveyed to the roller.

[0009] Preferably, the scraping structure includes a positioning rod that passes through the frame and is rotatably connected to the frame. The positioning rod has a circular cross-sectional shape, and an inclined scraper is fixedly embedded on the outer side of the positioning rod.

[0010] Preferably, the end of the inclined scraper away from the positioning rod is movably fitted with the roller, and two symmetrically distributed fixing blocks are fixedly embedded on the outer side of the positioning rod corresponding to the two ends of the inclined scraper, and the end of the inclined scraper near the roller is chamfered.

[0011] Preferably, an arc-shaped spring is fixedly installed on the outer side of the first fixing block, the arc-shaped spring can drive the positioning rod to rotate, and the end of the arc-shaped spring away from the first fixing block is fixedly connected to the second positioning block.

[0012] Preferably, the second positioning block is fixedly connected to the frame, and the inclined scraper is made of plastic. The inclined scraper can remove the material attached to the surface of the roller during the rotation of the roller.

[0013] Preferably, a knob is fixedly sleeved at the end of the positioning rod away from the air duct, and the knob is located on the outside of the frame. A bent connecting rod is movably embedded on the knob, and an anti-slip groove is provided on the outside of the knob.

[0014] Preferably, the connection between the bending link and the knob is a plug-in connection, and a pin is fixedly connected to one end of the bending link near the frame. The pin can prevent the bending link from disengaging from the knob, and the connection between the pin and the frame is a plug-in connection.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This utility model, through the installation of a blower, a cleaning structure, and a scraping structure, allows the roller brush in the cleaning structure to rotate and, in conjunction with the vacuum cleaner, sweep up and remove materials from the inside of the conveyor belt during vacuuming operation. The inclined scraper in the scraping structure can remove materials adhering to the surface of the roller during its rotation. The removed materials are also sucked away by the blower, which helps to prevent materials from falling between the roller brush and the roller. This effectively prevents some materials from getting stuck between the conveyor belt and the roller, thus effectively extending the service life of the conveyor belt.

[0017] 2. By installing a knob, bending connecting rod and pin, this utility model facilitates the rotation of the inclined scraper to move it away from the drum, thus avoiding severe wear caused by the inclined scraper being in contact with the drum for a long time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figure 1 , Figure 2 The diagram shows an intermediate drive conveyor line, including a frame 1, a roller 2 rotatably mounted on the frame 1, a conveyor belt 3 fitted to the outside of the roller 2, a duct 4 fixedly embedded in the frame 1 and close to the roller 2, a conduit 5 connected to the end of the duct 4 away from the frame 1, and a vacuum cleaner fixedly connected to the end of the conduit 5 away from the duct 4; a cleaning structure 6 for cleaning materials inside the frame 1, the cleaning structure 6 being installed inside the frame 1 and on the same horizontal line as the duct 4; and a scraping structure 7 for cleaning materials adhering to the surface of the roller 2, the scraping structure 7 being installed above the cleaning structure 6.

[0027] Please see Figure 3The cleaning structure 6 includes an impeller 601 rotatably mounted inside the air duct 4. The impeller 601 can rotate under the drive of airflow. A rotating shaft 602 is fixedly embedded at the end of the impeller 601 away from the duct 5.

[0028] Please see Figure 4 The rotating shaft 602 is rotatably connected to the frame 1 via a bearing. The bearing can reduce the friction between the rotating shaft 602 and the frame 1. A roller brush 603 is fixedly sleeved on the outer side of the rotating shaft 602. The roller brush 603 is in movable contact with the inner wall of the conveyor belt 3, and the rotation direction of the roller brush 603 is opposite to that of the conveyor belt 3. The roller brush 603 can prevent the material from being conveyed to the drum 2.

[0029] The working principle for preventing materials from getting stuck between the conveyor belt and the roller is as follows: When materials fall to the inside of the lower conveyor belt 3 due to their proximity to the edge of the conveyor belt 3, the airflow inside the air duct 4, connected to the vacuum cleaner via the conduit 5, drives the impeller 601 and the roller brush 603 to rotate. Since the roller brush 603 rotates in the opposite direction to the conveyor belt 3, it sweeps up the materials that have fallen to the inside of the conveyor belt 3. The swept-up materials are then sucked away by the air duct 4, thus effectively preventing the conveyor belt 3 from transporting the materials to the roller 2 and preventing the materials from getting stuck between the conveyor belt 3 and the roller 2. Example 2

[0030] Please see Figure 3 , Figure 5 This embodiment further explains Example 1. The scraping structure 7 includes a positioning rod 701 that passes through the frame 1 and is rotatably connected to the frame 1. The positioning rod 701 has a circular cross-sectional shape. An inclined scraper 702 is fixedly embedded on the outer side of the positioning rod 701. The end of the inclined scraper 702 away from the positioning rod 701 is movably attached to the roller 2. Two symmetrically distributed fixing blocks 703 are fixedly embedded on the outer side of the positioning rod 701 corresponding to the two ends of the inclined scraper 702. The end of the inclined scraper 702 near the roller 2 is chamfered.

[0031] Please see Figure 6 An arc spring 704 is fixedly installed on the outer side of the fixing block 703. The arc spring 704 can drive the positioning rod 701 to rotate. The end of the arc spring 704 away from the fixing block 703 is fixedly connected to the positioning block 705. The positioning block 705 is fixedly connected to the frame 1. The inclined scraper 702 is made of plastic. The inclined scraper 702 can remove the material attached to the surface of the roller 2 during its rotation.

[0032] In this embodiment: Since the inclined scraper 702 is in contact with the roller 2, the inclined scraper 702 will automatically remove the material falling on the roller 2 during the rotation of the roller 2. The scraped material will roll down along the inclined surface of the inclined scraper 702 and will be sucked away by the air duct 4 during the rolling process. This not only helps to remove the material attached to the roller 2, but also helps to prevent the material from falling between the roller brush 603 and the roller 2. Example 3

[0033] Please see Figure 5 This embodiment further illustrates other embodiments: a knob 8 is fixedly sleeved at the end of the positioning rod 701 away from the air duct 4, and the knob 8 is located on the outside of the frame 1. A bent connecting rod 9 is movably embedded on the knob 8, and an anti-slip groove is provided on the outside of the knob 8.

[0034] Please see Figure 5 The connection between the bending link 9 and the knob 8 is a plug-in connection. A pin 10 is fixedly connected to one end of the bending link 9 near the frame 1. The pin 10 can prevent the bending link 9 from disengaging from the knob 8, and the connection between the pin 10 and the frame 1 is a plug-in connection.

[0035] In this embodiment: when the conveyor belt 3 is conveying other items, the operator rotates the knob 8 to move the inclined scraper 702 away from the roller 2. Under the condition that the connection between the pin 10 and the frame 1 is a plug-in connection, the operator inserts the pin 10 into the frame 1 by bending the connecting rod 9 to position the inclined scraper 702. This can prevent the inclined scraper 702 from being in contact with the roller 2 for a long time and thus avoid severe wear.
