[0002] Conveyor belts are essential equipment in tobacco processing, used to transport tobacco to various processing stations. After prolonged use, a mixture of tobacco debris and oil can easily accumulate on the idler rollers. This accumulated dirt can affect the shape and profile of the idler rollers, causing the conveyor belt to run unevenly, or leading to belt misalignment and damage due to changes in the diameter at both ends of the idler rollers.

[0003] Currently, the cleaning and maintenance of conveyor belt idlers mainly relies on manual labor, with maintenance personnel using small shovels, iron bars, and other tools to remove surface dirt. However, due to the large width of some conveyor belts, cleaning tools are difficult to reach the middle of the idlers, and the tools lack a point of leverage, making them difficult to control, resulting in poor cleaning effectiveness.

[0025] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In existing technology, the conveyor belts used in tobacco production lines mainly consist of a frame, idlers, a belt, and a power system. The idlers are rotatably mounted on the frame at both ends. Several idlers are spaced apart along the extension direction of the frame, with the belt pressing against them. Because the idlers are located below the belt, and the conveyor belt frame is on both sides of the idlers, cleaning the idlers requires very little operating space, making the traditional manual hand-held tool operation extremely cumbersome.

[0027] To address the aforementioned problems, this utility model provides a cleaning device for tobacco conveyor belt idlers. The cleaning device includes two fixed bases 3, one on the left and one on the right. A drive mechanism is mounted on each of the two fixed bases at both ends. A scraper 5 is mounted on the drive mechanism for cleaning the idlers. The fixed bases 3 can be detachably mounted on the conveyor belt frame at both ends of the idlers.

[0028] The driving mechanism includes a lead screw 6, a guide rod 7, and a crank handle 1. The two ends of the lead screw 6 are rotatably mounted on two fixed bases 3. A crank handle 1 is provided at the end of the lead screw 6 to drive its rotation. The scraper 5 includes a threaded portion and is screwed onto the lead screw 6. The guide rod 7 is arranged parallel to the lead screw 6. The two ends of the guide rod 7 are mounted on two fixed bases 3. The scraper 5 has a through hole, and the guide rod 7 passes through the through hole of the scraper 5.

[0029] The fixed base 3 is used to stably mount the entire cleaning device on the frame. The drive mechanism is located between the two fixed bases 3. In use, the drive mechanism is set parallel to the idler roller, and the drive mechanism drives the scraper 5 to move along the axis of the idler roller. One side of the scraper 5 is mounted on the drive mechanism, and the other side has a blade that is in contact with the idler roller. In conjunction with the rotation of the idler roller itself, the blade can be used to scrape away dirt on the idler roller.

[0030] The drive mechanism includes a lead screw 6 and a guide rod 7. The guide rod 7 serves as a guide, being parallel to the idler roller, thus guiding the scraper 5 to move along the idler roller. The lead screw 6 drives the scraper 5 to move; the scraper 5 has a threaded hole that mates with the lead screw, or a lead screw nut that mates with the lead screw 6 is fixedly mounted on the scraper 5. A crank handle 1 is provided at the operating end or both ends of the lead screw 6 for driving its rotation.

[0031] The fixed base 3 serves as a support for mounting the drive mechanism, and its specific structure is a metal bracket. The fixed base 3 can be fixed to the conveyor belt frame and can be removed and reinstalled.

[0032] The fixed base 3 is equipped with a clamping and fixing mechanism, which can be detachably connected to the conveyor belt frame. The fixed base 3 includes a top plate, a side plate, and a bottom plate connected in sequence. The fixed base 3 is C-shaped. The fixed base 3 has a groove in the middle, which can be locked onto the conveyor belt frame. By using the groove on the fixed base 3 to lock onto the frame, the stability of the fixed base 3 during installation can be improved, and the cleaning effect of the scraper 5 can be avoided due to the shaking of the fixed base 3.

[0033] The clamping and fixing mechanism is used to lock the fixed base 3 to the frame. The clamping and fixing mechanism can be disassembled when needed. This application provides the following specific solutions for the clamping and fixing mechanism: (a) magnetic base, (b) clamp that can be locked to the frame, and (c) bolt that can mate with screw holes on the frame.

[0034] This utility model also proposes a preferred embodiment of the clamping and fixing mechanism, such as... Figure 1 As shown, the clamping and fixing mechanism includes a fixing bolt 4 mounted on the base plate. A threaded hole is formed in the base plate of the fixing base 3. The fixing bolt 4 is screwed into the threaded hole. The top of the fixing bolt 4 presses upward against the conveyor belt frame. In use, simply tighten the fixing bolt 4 so that its top presses against the frame, thereby forcing the top plate of the fixing base 3 to press downward against the frame, using friction to lock the fixing base 3 onto the frame.

[0035] When the idler roller cleaning device is working, in order to better control the distance between the scraper 5 and the idler roller and the downward pressure between the scraper 5 and the idler roller, the scraper 5 is set to be movable. In this way, by controlling one side of the scraper blade, it can be brought closer to or away from the idler roller, as well as the pressure between the scraper blade and the idler roller.

[0036] This utility model proposes a specific implementation method for controlling the blade of the scraper 5 using a rotating mechanism, as follows: A rotating mechanism is provided on the fixed base 3, and both ends of the guide rod 7 are mounted on the rotating mechanism. The rotating mechanism drives the guide rod 7 to rotate around the axis of the lead screw 6. The side of the scraper 5 away from the blade is mounted on the lead screw 6, and the rotating mechanism controls the scraper 5 to rotate around the lead screw 6. When the scraper 5 rotates, one side of its blade can move, thereby moving closer to or away from the idler roller.

[0037] The rotating mechanism includes two rocker arms 2, left and right. One end of each rocker arm 2 is fixedly connected to the end of the guide rod 7, and the other end is rotatably mounted on the fixed base 3. The rotation axis of the rocker arm 2 coincides with the rotation axis of the lead screw 6. The rotation of the rocker arm 2 will cause the guide rod 7 to rotate around the lead screw 6, and the rotation of the guide rod 7 will cause the scraper 5 to rotate.

[0038] A first bearing 8 is mounted on the fixed base 3. Both ends of the lead screw 6 are rotatably mounted on the first bearing 8. A second bearing is provided at the end of the rocker arm 2 away from the guide rod 7. The second bearing is mounted on the lead screw 6. The second bearing and the first bearing 8 are tightly abutted together by bushings. The two rocker arms 2 are located inside the two first bearings 8. The middle portion of the lead screw 6 is threaded, and the second bearing is sleeved on the unthreaded end of the lead screw 6.

[0039] A mounting base is provided on the fixed base 3, and the first bearing 8 is mounted on the mounting base. The lead screw 6 has a shoulder on the inner side of the second bearing, and the second bearing is positioned by the shoulder and the bushing.

[0040] The first bearing 8 is detachably connected to the fixed base 3, such as... Figure 1 As shown, the mounting base is installed on the fixed base 3 by bolts. The mounting base and the first bearing 8 can be removed together by removing the bolts.

[0041] The installation and use of idler roller cleaning devices includes the following processes:

[0042] a. Install the two fixed bases 3 into place respectively, and keep the fixing bolts 4 loose.

[0043] b. Connect both ends of the drive mechanism to the two fixed bases 3 respectively, and adjust the position of the fixed bases 3 at the same time.

[0044] c. Tighten the fixing bolts 4 on the fixed base 3 to fix the fixed base 3 to the frame.

[0045] d. Rotate rocker arm 2 to drive scraper 5 to move, so that the blade of scraper 5 is in close contact with the idler roller.

[0046] e. Turn the crank handle 1 to drive the lead screw 6 to rotate. When the lead screw 6 rotates, it drives the scraper 5 to move along the extension direction of the idler roller. Keep the idler roller in a rotating state, and the blade of the scraper 5 can gradually scrape off the dirt on the idler roller.

[0047] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0048] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately. Furthermore, various different embodiments of this utility model can also be combined arbitrarily, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
