Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, and in particular to a device for cleaning residues on electronic belt scales. Background Technology

[0002] In the cigarette manufacturing industry, tobacco leaf (shredded tobacco) flow control is fundamental to the control of tobacco temperature, flavoring, and moisture. Instability in flow will lead to abnormal water (drying), flavoring, and temperature control, thus affecting product quality. Tobacco leaf (shredded tobacco) flow control includes two aspects: continuous control and uniformity control, which is mainly achieved through metering and control using electronic belt scales.

[0003] When weighing tobacco leaves or shredded tobacco on an electronic belt scale, the flexible stop prevents some tobacco leaves and shredded tobacco from falling off the side of the conveyor belt. However, some tobacco leaves or shredded tobacco will accumulate on the flexible stop. Over time, the tobacco leaf or shredded tobacco residue will accumulate more and more, which will make the measurement results inaccurate. Therefore, a cleaning device is needed to clean the residue on the flexible stop in a timely manner. Utility Model Content

[0004] In view of this, the present application proposes a device for cleaning residue on an electronic belt scale, which removes residue from the electronic belt scale by moving a cleaning structure on a flexible stop.

The electronic belt scale includes a conveyor belt and baffles disposed on both sides of the conveyor belt. A flexible stop is provided at the lower end of the baffle. The flexible stop contacts both sides of the conveyor belt. The cleaning structure can move on the flexible stop to remove residue on the flexible stop.

[0006] Furthermore, the baffle is provided with strip-shaped holes, and the cleaning structure can move on the strip-shaped holes.

[0007] Furthermore, the cleaning structure is a nozzle with a hose through which compressed air is introduced and ejected from the nozzle to clean up residue.

[0008] Furthermore, the cleaning structure is a brush, one end of which contacts the flexible stop, and the other end is fixedly connected to a connecting rod, which moves within the strip hole.

[0009] Furthermore, the upper end of the strip hole is provided with a placement groove communicating with the strip hole, and the connecting rod is placed in the placement groove, so that the bottom of the brush is lifted away from the flexible stop.

[0010] Furthermore, the placement slot is inverted L-shaped.

[0011] Furthermore, it also includes a controller, which is disposed on the outer wall of the baffle and is electrically connected to the connecting rod to control the movement of the connecting rod.

[0012] Furthermore, a receiving box is provided at the bottom of the conveyor belt.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0020] refer to Figures 1 to 3 This application discloses a device for cleaning residue from an electronic belt scale, comprising an electronic belt scale and a cleaning structure 2 disposed on the electronic belt scale. The electronic belt scale includes a conveyor belt 11 and baffles 12 disposed on both sides of the conveyor belt 11. A flexible stop 13 is provided at the lower end of each baffle 12. One end of the flexible stop 13 is disposed on the baffle 12, and the other end contacts both sides of the conveyor belt 11. This arrangement is to prevent tobacco shreds or leaves from falling off the sides of the conveyor belt 11 when they fall onto it, thus preventing inaccurate data measured by the electronic belt scale. The flexible stop 13 is typically made of rubber and is arc-shaped, so that it does not obstruct the conveyor belt 11's rotation when in contact with it. While the flexible stop 13 is in contact with the conveyor belt 11, it prevents tobacco shreds or leaves from falling off the sides of the conveyor belt 11, thus preventing inaccurate data measured by the electronic belt scale. The system will stop some tobacco leaves and shreds from falling off the side of the conveyor belt 11. However, some tobacco leaves or shreds will accumulate on the flexible stop 13. Over time, the tobacco leaf or shred residue will accumulate more and more, making the measurement results inaccurate. Therefore, the cleaning structure 2 can move on the flexible stop 13 to clean the tobacco leaf or shred residue on the flexible stop 13. The cleaning structure 2 works after the electronic belt scale has finished weighing the tobacco leaves or shreds. That is, when the cleaning structure 2 cleans the tobacco leaf or shred residue on the flexible stop 13, the electronic belt scale does not perform instantaneous weighing. Some residue will be transferred to the conveyor belt 11 by the cleaning action of the cleaning structure 2. Therefore, the conveyor belt 11 continues to operate so that the residue transferred to the conveyor belt 11 will leave the conveyor belt 11 as the conveyor belt 11 rotates.

[0021] The baffle 12 is provided with a strip hole 14, and the cleaning structure 2 can move on the strip hole 14, thereby realizing the movement of the cleaning structure 2 on the flexible stop part 13.

[0022] The cleaning structure 2 is a nozzle 22 with a flexible hose 21. The nozzle 22 faces downward and is a certain distance away from the flexible stop part 13. Compressed air is introduced into the flexible hose 21 and then sprayed out from the nozzle 22, which can clean the residue below the nozzle 22. The nozzle 22 moves on the strip hole 14 to achieve the function of cleaning the tobacco leaf or tobacco residue on the flexible stop part 13.

[0023] The cleaning structure 2 can also be a brush 31. One end of the brush 31 contacts the flexible stop part 13 so as to remove the residue on the flexible stop part 13. The other end of the brush 31 is fixedly connected to a connecting rod 32. The connecting rod 32 moves in the strip hole 14 to drive the brush 31 to move on the flexible stop part 13 and clean the residue on the flexible stop part 13.

[0024] The upper end of the strip hole 14 is provided with a placement groove 15 that communicates with the strip hole 14. The connecting rod 32 is moved and placed in the placement groove 15, so that the bottom of the brush 31 is lifted away from the flexible stop part 13. The placement groove 15 is provided so that after the brush 31 cleans the residue on the flexible stop part 13, the bottom of the brush 31 is lifted away from the flexible stop part 13, so as not to affect the stopping function of the flexible stop part 13 and the conveying function of the conveyor belt 11.

[0025] Preferably, the placement slot 15 is inverted L-shaped.

[0026] This application also includes a controller 4, which is disposed on the outer wall of the baffle 12. The controller 4 is electrically connected to the connecting rod 32 to control the movement of the connecting rod 32. That is, when the flexible stop part 13 needs to be cleaned, the controller 4 controls the connecting rod 32 to move on the flexible stop part 13 to clean the residue on the flexible stop part 13. After the residue is cleaned, the controller 4 controls the movement of the connecting rod 32 again, so that the connecting rod 32 moves into the placement groove 15, so that the bottom of the brush 31 is lifted away from the flexible stop part 13, so as not to affect the stopping function of the flexible stop part 13 and the conveying function of the conveyor belt 11.

[0027] The bottom of the conveyor belt 11 is provided with a receiving box to receive tobacco leaf or tobacco residue cleaned off from the flexible stop 13.
